+/*
+ * The Lazy Doctor.
+ *
+ * This tool automatically builds up-to-date class documentation for all classes
+ * that derive from LazyJsonMapper, and documents their virtual properties and
+ * functions by adding "@property" and "@method" declarations to their class
+ * PHPdoc blocks. That documentation is necessary for things like code analysis
+ * tools and IDE autocomplete for all of your virtual properties/functions!
+ *
+ * LazyDoctor also performs class diagnostics: It compiles the class property
+ * maps of _all_ of your LazyJsonMapper-based classes, which means that you can
+ * be 100% sure that all of your maps are valid if this tool runs successfully.
+ *
+ * To see all available options, type "./vendor/bin/lazydoctor --help".
+ *
+ * To begin, simply point the "--composer" option at the "composer.json" file
+ * for your project. Just be aware that your project MUST be based on PSR-4
+ * autoloading, with ONE OR MORE defined autoload-namespaces in "composer.json".
+ *
+ * You can read more about PSR-4 autoloading at the official Composer site:
+ *
+ * https://getcomposer.org/doc/04-schema.md#autoload
+ *
+ * This tool will ONLY parse classes that properly follow PSR-4 autoloading!
+ *
+ * In addition to the composer-file, you'll also have to specify whether you
+ * want to document virtual "--properties", virtual "--functions", or BOTH.
+ * Note that we'll ONLY document them when the individual classes support that
+ * kind of access (when it hasn't disabled its class-option for that feature).
+ *
+ * If you don't provide any documentation flags, we'll instead REMOVE all of
+ * the current class "virtual @property/@method" documentation. That can be
+ * useful for restoring your files if you don't want to document them anymore.
+ *
+ * You should also be aware of "--document-overridden", which will document
+ * virtual properties or functions even if they're already manually defined
+ * (overridden) by the class or its parents. That can be useful if you want to
+ * ensure that you ALWAYS document the virtual properties/functions in all of
+ * your class files even when it has been overridden somewhere. In that case,
+ * you should ensure that your overridden properties/functions have the SAME or
+ * a COMPATIBLE signature & return value, so their auto-docs are still correct.
+ *
+ * Tip: You can use the "--validate-only" param to check docs without writing to
+ * disk. That can be useful when making a non-destructive Git "pre-commit hook"
+ * to validate your repo and ensure that all files have updated documentation!
+ *
+ * This script always uses exit codes to indicate success. A non-zero exit code
+ * indicates that some files needed new class docs (in "--validate-only" mode),
+ * or that there was a general problem while processing.
+ *
+ * Lastly, you may appreciate the ability to silence all unimportant status
+ * messages! To do so, simply use ">/dev/null" to send STDOUT to the void...
+ * That way you'll ONLY see critical status messages during the processing.

+
+This package provides an asynchronous MQTT client built on the [React socket](https://github.com/reactphp/socket) library. All client methods return a promise which is fulfilled if the operation succeeded or rejected if the operation failed. Incoming messages of subscribed topics are delivered via the "message" event.
+
+## Install
+
+Via composer:
+
+``` bash
+$ composer require binsoul/net-mqtt-client-react
+```
+
+## Example
+
+Connect to a public broker and run forever.
+
+``` php

+  ```
+
+## 1.0.0 (2017-06-10)
+
+* First stable release, now following SemVer
+
+> Contains no other changes, so it's actually fully compatible with the v0.3.2 release.
+
+## 0.3.2 (2017-06-10)
+
+* Fix: Fix rejecting invalid URIs and unexpected URI schemes
+  (#13 by @clue)
+
+* Fix HHVM build for now again and ignore future HHVM build errors

+  (#11 by @clue)
+
+## 0.3.1 (2017-05-10)
+
+* Feature: Forward compatibility with upcoming Socket v1.0 and v0.8
+  (#10 by @clue)
+
+## 0.3.0 (2017-04-10)
+
+* Feature / BC break: Replace deprecated SocketClient with new Socket component
+  (#9 by @clue)
+
+  This implies that the `ProxyConnector` from this package now implements the
+  `React\Socket\ConnectorInterface` instead of the legacy
+  `React\SocketClient\ConnectorInterface`.
+
+## 0.2.0 (2017-04-10)
+
+* Feature / BC break: Update SocketClient to v0.7 or v0.6 and
+  use `connect($uri)` instead of `create($host, $port)`
+  (#8 by @clue)
+
+  ```php
+  // old
+  $connector->create($host, $port)->then(function (Stream $conn) {
+      $conn->write("…");
+  });
+
+  // new
+  $connector->connect($uri)->then(function (ConnectionInterface $conn) {
+      $conn->write("…");
+  });
+  ```
+
+* Improve test suite by adding PHPUnit to require-dev
+  (#7 by @clue)
+
+
+## 0.1.0 (2016-11-01)

+# clue/http-proxy-react [![Build Status](https://travis-ci.org/clue/php-http-proxy-react.svg?branch=master)](https://travis-ci.org/clue/php-http-proxy-react)
+
+Async HTTP proxy connector, use any TCP/IP-based protocol through an HTTP
+CONNECT proxy server, built on top of [ReactPHP](https://reactphp.org).
+
+HTTP CONNECT proxy servers (also commonly known as "HTTPS proxy" or "SSL proxy")
+are commonly used to tunnel HTTPS traffic through an intermediary ("proxy"), to
+conceal the origin address (anonymity) or to circumvent address blocking
+(geoblocking). While many (public) HTTP CONNECT proxy servers often limit this
+to HTTPS port `443` only, this can technically be used to tunnel any
+TCP/IP-based protocol (HTTP, SMTP, IMAP etc.).
+This library provides a simple API to create these tunneled connection for you.
+Because it implements ReactPHP's standard
+[`ConnectorInterface`](https://github.com/reactphp/socket#connectorinterface),
+it can simply be used in place of a normal connector.
+This makes it fairly simple to add HTTP CONNECT proxy support to pretty much any
+existing higher-level protocol implementation.
+
+* **Async execution of connections** -
+  Send any number of HTTP CONNECT requests in parallel and process their
+  responses as soon as results come in.
+  The Promise-based design provides a *sane* interface to working with out of
+  bound responses and possible connection errors.
+* **Standard interfaces** -
+  Allows easy integration with existing higher-level components by implementing
+  ReactPHP's standard
+  [`ConnectorInterface`](https://github.com/reactphp/socket#connectorinterface).
+* **Lightweight, SOLID design** -
+  Provides a thin abstraction that is [*just good enough*](http://en.wikipedia.org/wiki/Principle_of_good_enough)
+  and does not get in your way.
+  Builds on top of well-tested components and well-established concepts instead of reinventing the wheel.
+* **Good test coverage** -
+  Comes with an automated tests suite and is regularly tested against actual proxy servers in the wild

+### Quickstart example
+
+The following example code demonstrates how this library can be used to send a
+secure HTTPS request to google.com through a local HTTP proxy server:
+
+```php
+$loop = React\EventLoop\Factory::create();
+
+$proxy = new ProxyConnector('127.0.0.1:8080', new Connector($loop));
+$connector = new Connector($loop, array(
+    'tcp' => $proxy,
+    'timeout' => 3.0,
+    'dns' => false
+));
+
+$connector->connect('tls://google.com:443')->then(function (ConnectionInterface $stream) {
+    $stream->write("GET / HTTP/1.1\r\nHost: google.com\r\nConnection: close\r\n\r\n");
+    $stream->on('data', function ($chunk) {

+
+## Usage
+
+### ProxyConnector
+
+The `ProxyConnector` is responsible for creating plain TCP/IP connections to
+any destination by using an intermediary HTTP CONNECT proxy.
+
+```
+[you] -> [proxy] -> [destination]
+```
+
+Its constructor simply accepts an HTTP proxy URL and a connector used to connect
+to the proxy server address:
+
+```php
+$connector = new Connector($loop);
+$proxy = new ProxyConnector('http://127.0.0.1:8080', $connector);
+```
+
+The proxy URL may or may not contain a scheme and port definition. The default
+port will be `80` for HTTP (or `443` for HTTPS), but many common HTTP proxy
+servers use custom ports (often the alternative HTTP port `8080`).
+In its most simple form, the given connector will be a
+[`\React\Socket\Connector`](https://github.com/reactphp/socket#connector) if you
+want to connect to a given IP address as above.
+
+This is the main class in this package.
+Because it implements ReactPHP's standard
+[`ConnectorInterface`](https://github.com/reactphp/socket#connectorinterface),
+it can simply be used in place of a normal connector.
+Accordingly, it provides only a single public method, the
+[`connect()`](https://github.com/reactphp/socket#connect) method.
+The `connect(string $uri): PromiseInterface<ConnectionInterface, Exception>`
+method can be used to establish a streaming connection.
+It returns a [Promise](https://github.com/reactphp/promise) which either
+fulfills with a [ConnectionInterface](https://github.com/reactphp/socket#connectioninterface)
+on success or rejects with an `Exception` on error.
+
+This makes it fairly simple to add HTTP CONNECT proxy support to pretty much any
+higher-level component:
+
+```diff
+- $client = new SomeClient($connector);
++ $proxy = new ProxyConnector('http://127.0.0.1:8080', $connector);
++ $client = new SomeClient($proxy);
+```
+
+#### Plain TCP connections
+
+HTTP CONNECT proxies are most frequently used to issue HTTPS requests to your destination.
+However, this is actually performed on a higher protocol layer and this
+connector is actually inherently a general-purpose plain TCP/IP connector.
+As documented above, you can simply invoke its `connect()` method to establish
+a streaming plain TCP/IP connection and use any higher level protocol like so:
+
+```php
+$proxy = new ProxyConnector('http://127.0.0.1:8080', $connector);
+
+$proxy->connect('tcp://smtp.googlemail.com:587')->then(function (ConnectionInterface $stream) {
+    $stream->write("EHLO local\r\n");
+    $stream->on('data', function ($chunk) use ($stream) {
+        echo $chunk;
+    });
+});
+```
+
+You can either use the `ProxyConnector` directly or you may want to wrap this connector
+in ReactPHP's [`Connector`](https://github.com/reactphp/socket#connector):
+
+```php
+$connector = new Connector($loop, array(
+    'tcp' => $proxy,
+    'dns' => false
+));
+
+$connector->connect('tcp://smtp.googlemail.com:587')->then(function (ConnectionInterface $stream) {
+    $stream->write("EHLO local\r\n");
+    $stream->on('data', function ($chunk) use ($stream) {
+        echo $chunk;
+    });
+});
+```
+
+Note that HTTP CONNECT proxies often restrict which ports one may connect to.
+Many (public) proxy servers do in fact limit this to HTTPS (443) only.
+
+#### Secure TLS connections
+
+This class can also be used if you want to establish a secure TLS connection
+(formerly known as SSL) between you and your destination, such as when using
+secure HTTPS to your destination site. You can simply wrap this connector in
+ReactPHP's [`Connector`](https://github.com/reactphp/socket#connector) or the
+low-level [`SecureConnector`](https://github.com/reactphp/socket#secureconnector):
+
+```php
+$proxy = new ProxyConnector('http://127.0.0.1:8080', $connector);
+$connector = new Connector($loop, array(
+    'tcp' => $proxy,
+    'dns' => false
+));
+
+$connector->connect('tls://smtp.googlemail.com:465')->then(function (ConnectionInterface $stream) {
+    $stream->write("EHLO local\r\n");
+    $stream->on('data', function ($chunk) use ($stream) {
+        echo $chunk;
+    });
+});
+```
+
+> Note how secure TLS connections are in fact entirely handled outside of
+  this HTTP CONNECT client implementation.
+
+#### Connection timeout
+
+By default, the `ProxyConnector` does not implement any timeouts for establishing remote
+connections.
+Your underlying operating system may impose limits on pending and/or idle TCP/IP
+connections, anywhere in a range of a few minutes to several hours.
+
+Many use cases require more control over the timeout and likely values much
+smaller, usually in the range of a few seconds only.
+
+You can use ReactPHP's [`Connector`](https://github.com/reactphp/socket#connector)
+or the low-level
+[`TimeoutConnector`](https://github.com/reactphp/socket#timeoutconnector)
+to decorate any given `ConnectorInterface` instance.
+It provides the same `connect()` method, but will automatically reject the
+underlying connection attempt if it takes too long:
+
+```php
+$connector = new Connector($loop, array(
+    'tcp' => $proxy,
+    'dns' => false,
+    'timeout' => 3.0
+));
+
+$connector->connect('tcp://google.com:80')->then(function ($stream) {
+    // connection succeeded within 3.0 seconds
+});
+```
+
+See also any of the [examples](examples).
+
+> Note how connection timeout is in fact entirely handled outside of this
+  HTTP CONNECT client implementation.
+
+#### DNS resolution
+
+By default, the `ProxyConnector` does not perform any DNS resolution at all and simply
+forwards any hostname you're trying to connect to the remote proxy server.
+The remote proxy server is thus responsible for looking up any hostnames via DNS
+(this default mode is thus called *remote DNS resolution*).
+
+As an alternative, you can also send the destination IP to the remote proxy
+server.
+In this mode you either have to stick to using IPs only (which is ofen unfeasable)
+or perform any DNS lookups locally and only transmit the resolved destination IPs
+(this mode is thus called *local DNS resolution*).
+
+The default *remote DNS resolution* is useful if your local `ProxyConnector` either can
+not resolve target hostnames because it has no direct access to the internet or
+if it should not resolve target hostnames because its outgoing DNS traffic might
+be intercepted.
+
+As noted above, the `ProxyConnector` defaults to using remote DNS resolution.
+However, wrapping the `ProxyConnector` in ReactPHP's
+[`Connector`](https://github.com/reactphp/socket#connector) actually
+performs local DNS resolution unless explicitly defined otherwise.
+Given that remote DNS resolution is assumed to be the preferred mode, all
+other examples explicitly disable DNS resoltion like this:
+
+```php
+$connector = new Connector($loop, array(
+    'tcp' => $proxy,
+    'dns' => false
+));
+```
+
+If you want to explicitly use *local DNS resolution*, you can use the following code:
+
+```php
+// set up Connector which uses Google's public DNS (8.8.8.8)
+$connector = Connector($loop, array(
+    'tcp' => $proxy,
+    'dns' => '8.8.8.8'
+));
+```
+
+> Note how local DNS resolution is in fact entirely handled outside of this
+  HTTP CONNECT client implementation.
+
+#### Authentication
+
+If your HTTP proxy server requires authentication, you may pass the username and
+password as part of the HTTP proxy URL like this:
+
+```php
+$proxy = new ProxyConnector('http://user:pass@127.0.0.1:8080', $connector);
+```
+
+Note that both the username and password must be percent-encoded if they contain
+special characters:
+
+```php
+$user = 'he:llo';
+$pass = 'p@ss';
+
+$proxy = new ProxyConnector(
+    rawurlencode($user) . ':' . rawurlencode($pass) . '@127.0.0.1:8080',
+    $connector
+);
+```
+
+> The authentication details will be used for basic authentication and will be
+  transferred in the `Proxy-Authorization` HTTP request header for each
+  connection attempt.
+  If the authentication details are missing or not accepted by the remote HTTP
+  proxy server, it is expected to reject each connection attempt with a
+  `407` (Proxy Authentication Required) response status code and an exception
+  error code of `SOCKET_EACCES` (13).
+
+#### Advanced secure proxy connections
+
+Note that communication between the client and the proxy is usually via an
+unencrypted, plain TCP/IP HTTP connection. Note that this is the most common
+setup, because you can still establish a TLS connection between you and the
+destination host as above.
+
+If you want to connect to a (rather rare) HTTPS proxy, you may want use the
+`https://` scheme (HTTPS default port 443) and use ReactPHP's
+[`Connector`](https://github.com/reactphp/socket#connector) or the low-level
+[`SecureConnector`](https://github.com/reactphp/socket#secureconnector)
+instance to create a secure connection to the proxy:
+
+```php
+$connector = new Connector($loop);
+$proxy = new ProxyConnector('https://127.0.0.1:443', $connector);
+
+$proxy->connect('tcp://smtp.googlemail.com:587');
+```
+
+#### Advanced Unix domain sockets
+
+HTTP CONNECT proxy servers support forwarding TCP/IP based connections and
+higher level protocols.
+In some advanced cases, it may be useful to let your HTTP CONNECT proxy server
+listen on a Unix domain socket (UDS) path instead of a IP:port combination.
+For example, this allows you to rely on file system permissions instead of
+having to rely on explicit [authentication](#authentication).
+
+You can simply use the `http+unix://` URI scheme like this:
+
+```php
+$proxy = new ProxyConnector('http+unix:///tmp/proxy.sock', $connector);
+
+$proxy->connect('tcp://google.com:80')->then(function (ConnectionInterface $stream) {
+    // connected…
+});
+```
+
+Similarly, you can also combine this with [authentication](#authentication)
+like this:
+
+```php
+$proxy = new ProxyConnector('http+unix://user:pass@/tmp/proxy.sock', $connector);
+```
+
+> Note that Unix domain sockets (UDS) are considered advanced usage and PHP only
+  has limited support for this.
+  In particular, enabling [secure TLS](#secure-tls-connections) may not be
+  supported.
+
+> Note that the HTTP CONNECT protocol does not support the notion of UDS paths.
+  The above works reasonably well because UDS is only used for the connection between
+  client and proxy server and the path will not actually passed over the protocol.
+  This implies that this does not support connecting to UDS destination paths.
+
+## Install
+
+The recommended way to install this library is [through Composer](https://getcomposer.org).

+* If you want to learn more about processing streams of data, refer to the
+  documentation of the underlying
+  [react/stream](https://github.com/reactphp/stream) component.
+* As an alternative to an HTTP CONNECT proxy, you may also want to look into
+  using a SOCKS (SOCKS4/SOCKS5) proxy instead.
+  You may want to use [clue/socks-react](https://github.com/clue/php-socks-react)
+  which also provides an implementation of the same
+  [`ConnectorInterface`](https://github.com/reactphp/socket#connectorinterface)
+  so that supporting either proxy protocol should be fairly trivial.
+* If you're dealing with public proxies, you'll likely have to work with mixed
+  quality and unreliable proxies. You may want to look into using
+  [clue/connection-manager-extra](https://github.com/clue/php-connection-manager-extra)
+  which allows retrying unreliable ones, implying connection timeouts,
+  concurrently working with multiple connectors and more.
+* If you're looking for an end-user HTTP CONNECT proxy server daemon, you may
+  want to use [LeProxy](https://leproxy.org/).

+    $promise = $proxy->connect('imap.example.com:143');
+    $promise->then(null, function (Exeption $e) {
+        if ($e->getCode() === SOCKET_EACCES) {
+            echo 'Failed to authenticate with proxy!';

+## 0.8.1 (2017-04-21)
+
+*   Update examples to use URIs with default port 1080 and accept proxy URI arguments
+    (#54 by @clue)
+
+*   Remove now unneeded dependency on `react/stream`
+    (#55 by @clue)
+
+## 0.8.0 (2017-04-18)
+
+*   Feature: Merge `Server` class from clue/socks-server
+    (#52 by @clue)
+
+    ```php
+    $socket = new React\Socket\Server(1080, $loop);
+    $server = new Clue\React\Socks\Server($loop, $socket);
+    ```
+
+    > Upgrading from [clue/socks-server](https://github.com/clue/php-socks-server)?
+      The classes have been moved as-is, so you can simply start using the new
+      class name `Clue\React\Socks\Server` with no other changes required.
+
+## 0.7.0 (2017-04-14)
+
+*   Feature / BC break: Replace depreacted SocketClient with Socket v0.7 and
+    use `connect($uri)` instead of `create($host, $port)`
+    (#51 by @clue)
+
+    ```php
+    // old
+    $connector = new React\SocketClient\TcpConnector($loop);
+    $client = new Client(1080, $connector);
+    $client->create('google.com', 80)->then(function (Stream $conn) {
+        $conn->write("…");
+    });
+
+    // new
+    $connector = new React\Socket\TcpConnector($loop);
+    $client = new Client(1080, $connector);
+    $client->connect('google.com:80')->then(function (ConnectionInterface $conn) {
+        $conn->write("…");
+    });
+    ```
+
+*   Improve test suite by adding PHPUnit to require-dev
+    (#50 by @clue)
+
+## 0.6.0 (2016-11-29)
+
+* Feature / BC break: Pass connector into `Client` instead of loop, remove unneeded deps
+  (#49 by @clue)
+
+  ```php
+  // old (connector is create implicitly)
+  $client = new Client('127.0.0.1', $loop);
+
+  // old (connector can optionally be passed)
+  $client = new Client('127.0.0.1', $loop, $connector);
+
+  // new (connector is now mandatory)
+  $connector = new React\SocketClient\TcpConnector($loop);
+  $client = new Client('127.0.0.1', $connector);
+  ```
+
+* Feature / BC break: `Client` now implements `ConnectorInterface`, remove `Connector` adapter
+  (#47 by @clue)
+
+  ```php
+  // old (explicit connector functions as an adapter)
+  $connector = $client->createConnector();
+  $promise = $connector->create('google.com', 80);
+
+  // new (client can be used as connector right away)
+  $promise = $client->create('google.com', 80);
+  ```
+
+* Feature / BC break: Remove `createSecureConnector()`, use `SecureConnector` instead
+  (#47 by @clue)
+
+  ```php
+  // old (tight coupling and hidden dependency)
+  $tls = $client->createSecureConnector();
+  $promise = $tls->create('google.com', 443);
+
+  // new (more explicit, loose coupling)
+  $tls = new React\SocketClient\SecureConnector($client, $loop);
+  $promise = $tls->create('google.com', 443);
+  ```
+
+* Feature / BC break: Remove `setResolveLocal()` and local DNS resolution and default to remote DNS resolution, use `DnsConnector` instead
+  (#44 by @clue)
+
+  ```php
+  // old (implicitly defaults to true, can be disabled)
+  $client->setResolveLocal(false);
+  $tcp = $client->createConnector();
+  $promise = $tcp->create('google.com', 80);
+
+  // new (always disabled, can be re-enabled like this)
+  $factory = new React\Dns\Resolver\Factory();
+  $resolver = $factory->createCached('8.8.8.8', $loop);
+  $tcp = new React\SocketClient\DnsConnector($client, $resolver);
+  $promise = $tcp->create('google.com', 80);
+  ```
+
+* Feature / BC break: Remove `setTimeout()`, use `TimeoutConnector` instead
+  (#45 by @clue)
+
+  ```php
+  // old (timeout only applies to TCP/IP connection)
+  $client = new Client('127.0.0.1', …);
+  $client->setTimeout(3.0);
+  $tcp = $client->createConnector();
+  $promise = $tcp->create('google.com', 80);
+
+  // new (timeout can be added to any layer)
+  $client = new Client('127.0.0.1', …);
+  $tcp = new React\SocketClient\TimeoutConnector($client, 3.0, $loop);
+  $promise = $tcp->create('google.com', 80);
+  ```
+
+* Feature / BC break: Remove `setProtocolVersion()` and `setAuth()` mutators, only support SOCKS URI for protocol version and authentication (immutable API)
+  (#46 by @clue)
+
+  ```php
+  // old (state can be mutated after instantiation)
+  $client = new Client('127.0.0.1', …);
+  $client->setProtocolVersion('5');
+  $client->setAuth('user', 'pass');
+
+  // new (immutable after construction, already supported as of v0.5.2 - now mandatory)
+  $client = new Client('socks5://user:pass@127.0.0.1', …);
+  ```
+
+## 0.5.2 (2016-11-25)
+
+* Feature: Apply protocol version and username/password auth from SOCKS URI
+  (#43 by @clue)
+
+  ```php
+  // explicitly use SOCKS5
+  $client = new Client('socks5://127.0.0.1', $loop);
+
+  // use authentication (automatically SOCKS5)
+  $client = new Client('user:pass@127.0.0.1', $loop);
+  ```
+
+* More explicit client examples, including proxy chaining
+  (#42 by @clue)
+
+## 0.5.1 (2016-11-21)
+
+* Feature: Support Promise cancellation
+  (#39 by @clue)
+
+  ```php
+  $promise = $connector->create($host, $port);
+
+  $promise->cancel();
+  ```
+
+* Feature: Timeout now cancels pending connection attempt
+  (#39, #22 by @clue)
+
+## 0.5.0 (2016-11-07)
+
+* Remove / BC break: Split off Server to clue/socks-server
+  (#35 by @clue)
+
+  > Upgrading? Check [clue/socks-server](https://github.com/clue/php-socks-server) for details.
+
+* Improve documentation and project structure
+
+## 0.4.0 (2016-03-19)
+
+* Feature: Support proper SSL/TLS connections with additional SSL context options
+  (#31, #33 by @clue)
+
+* Documentation for advanced Connector setups (bindto, multihop)
+  (#32 by @clue)
+
+## 0.3.0 (2015-06-20)
+
+* BC break / Feature: Client ctor now accepts a SOCKS server URI
+  ([#24](https://github.com/clue/php-socks-react/pull/24))
+  
+    ```php
+// old
+$client = new Client($loop, 'localhost', 9050);
+
+// new
+$client = new Client('localhost:9050', $loop);
+```
+
+* Feature: Automatically assume default SOCKS port (1080) if not given explicitly
+  ([#26](https://github.com/clue/php-socks-react/pull/26))
+
+* Improve documentation and test suite
+
+## 0.2.1 (2014-11-13)
+
+* Support React PHP v0.4 (while preserving BC with React PHP v0.3)
+  ([#16](https://github.com/clue/php-socks-react/pull/16))
+
+* Improve examples and add first class support for HHVM
+  ([#15](https://github.com/clue/php-socks-react/pull/15) and [#17](https://github.com/clue/php-socks-react/pull/17))
+
+## 0.2.0 (2014-09-27)
+
+* BC break / Feature: Simplify constructors by making parameters optional.
+  ([#10](https://github.com/clue/php-socks-react/pull/10))
+  
+  The `Factory` has been removed, you can now create instances of the `Client`
+  and `Server` yourself:
+  
+  ```php
+  // old
+  $factory = new Factory($loop, $dns);
+  $client = $factory->createClient('localhost', 9050);
+  $server = $factory->createSever($socket);
+  
+  // new
+  $client = new Client($loop, 'localhost', 9050);
+  $server = new Server($loop, $socket);
+  ```
+
+* BC break: Remove HTTP support and link to [clue/buzz-react](https://github.com/clue/php-buzz-react) instead.
+  ([#9](https://github.com/clue/php-socks-react/pull/9))
+  
+  HTTP operates on a different layer than this low-level SOCKS library.
+  Removing this reduces the footprint of this library.
+  
+  > Upgrading? Check the [README](https://github.com/clue/php-socks-react#http-requests) for details.  
+
+* Fix: Refactored to support other, faster loops (libev/libevent)
+  ([#12](https://github.com/clue/php-socks-react/pull/12))
+
+* Explicitly list dependencies, clean up examples and extend test suite significantly
+
+## 0.1.0 (2014-05-19)
+
+* First stable release
+* Async SOCKS `Client` and `Server` implementation
+* Project was originally part of [clue/socks](https://github.com/clue/php-socks)
+  and was split off from its latest releave v0.4.0
+  ([#1](https://github.com/clue/reactphp-socks/issues/1))
+
+> Upgrading from clue/socks v0.4.0? Use namespace `Clue\React\Socks` instead of `Socks` and you're ready to go!
+
+## 0.0.0 (2011-04-26)
+
+* Initial concept, originally tracked as part of
+  [clue/socks](https://github.com/clue/php-socks)

+## Quickstart example
+
+Once [installed](#install), you can use the following code to create a connection
+to google.com via a local SOCKS proxy server:
+
+```php
+$loop = React\EventLoop\Factory::create();
+$client = new Client('127.0.0.1:1080', new Connector($loop));
+
+$client->connect('tcp://www.google.com:80')->then(function (ConnectionInterface $stream) {
+    $stream->write("GET / HTTP/1.0\r\n\r\n");
+});
+
+$loop->run();
+```
+
+If you're not already running any other [SOCKS proxy server](#servers),
+you can use the following code to create a SOCKS
+proxy server listening for connections on `localhost:1080`:
+
+```php
+$loop = React\EventLoop\Factory::create();
+
+// listen on localhost:1080
+$socket = new Socket('127.0.0.1:1080', $loop);
+
+// start a new server listening for incoming connection on the given socket
+$server = new Server($loop, $socket);
+
+$loop->run();
+```
+
+See also the [examples](examples).
+
+## Usage
+
+### ConnectorInterface
+
+The `ConnectorInterface` is responsible for providing an interface for
+establishing streaming connections, such as a normal TCP/IP connection.
+
+In order to use this library, you should understand how this integrates with its
+ecosystem.
+This base interface is actually defined in React's
+[Socket component](https://github.com/reactphp/socket) and used
+throughout React's ecosystem.
+
+Most higher-level components (such as HTTP, database or other networking
+service clients) accept an instance implementing this interface to create their
+TCP/IP connection to the underlying networking service.
+This is usually done via dependency injection, so it's fairly simple to actually
+swap this implementation against this library in order to connect through a
+SOCKS proxy server.
+
+The interface only offers a single method:
+
+#### connect()
+
+The `connect(string $uri): PromiseInterface<ConnectionInterface, Exception>` method
+can be used to establish a streaming connection.
+It returns a [Promise](https://github.com/reactphp/promise) which either
+fulfills with a [ConnectionInterface](https://github.com/reactphp/socket#connectioninterface) or
+rejects with an `Exception`:
+
+```php
+$connector->connect('tcp://google.com:80')->then(
+    function (ConnectionInterface $stream) {
+        // connection successfully established
+    },
+    function (Exception $error) {
+        // failed to connect due to $error
+    }
+);
+```
+
+### Client
+
+The `Client` is responsible for communication with your SOCKS server instance.
+Its constructor simply accepts an SOCKS proxy URI and a connector used to
+connect to the SOCKS proxy server address.
+
+In its most simple form, you can simply pass React's
+[`Connector`](https://github.com/reactphp/socket#connector)
+like this:
+
+```php
+$connector = new React\Socket\Connector($loop);
+$client = new Client('127.0.0.1:1080', $connector);
+```
+
+You can omit the port if you're using the default SOCKS port 1080:
+
+```php
+$client = new Client('127.0.0.1', $connector);
+```
+
+If you need custom connector settings (DNS resolution, timeouts etc.), you can explicitly pass a
+custom instance of the [`ConnectorInterface`](https://github.com/reactphp/socket#connectorinterface):
+
+```php
+// use local DNS server
+$dnsResolverFactory = new DnsFactory();
+$resolver = $dnsResolverFactory->createCached('127.0.0.1', $loop);
+
+// outgoing connections to SOCKS server via interface 192.168.10.1
+// this is not to be confused with local DNS resolution (see further below)
+$connector = new DnsConnector(
+    new TcpConnector($loop, array('bindto' => '192.168.10.1:0')),
+    $resolver
+);
+
+$client = new Client('my-socks-server.local:1080', $connector);
+```
+
+This is the main class in this package.
+Because it implements the the [`ConnectorInterface`](#connectorinterface), it
+can simply be used in place of a normal connector.
+This makes it fairly simple to add SOCKS proxy support to pretty much any
+higher-level component:
+
+```diff
+- $client = new SomeClient($connector);
++ $proxy = new Client('127.0.0.1:1080', $connector);
++ $client = new SomeClient($proxy);
+```
+
+#### Plain TCP connections
+
+The `Client` implements the [`ConnectorInterface`](#connectorinterface) and
+hence provides a single public method, the [`connect()`](#connect) method.
+Let's open up a streaming TCP/IP connection and write some data:
+
+```php
+$client->connect('tcp://www.google.com:80')->then(function (ConnectonInterface $stream) {
+    echo 'connected to www.google.com:80';
+    $stream->write("GET / HTTP/1.0\r\n\r\n");
+    // ...
+});
+```
+
+You can either use the `Client` directly or you may want to wrap this connector
+in React's [`Connector`](https://github.com/reactphp/socket#connector):
+
+```php
+$connector = new React\Socket\Connector($loop, array(
+    'tcp' => $client,
+    'dns' => false
+));
+
+$connector->connect('tcp://www.google.com:80')->then(function (ConnectonInterface $stream) {
+    echo 'connected to www.google.com:80';
+    $stream->write("GET / HTTP/1.0\r\n\r\n");
+    // ...
+});
+
+```
+
+See also the [first example](examples).
+
+The `tcp://` scheme can also be omitted.
+Passing any other scheme will reject the promise.
+
+Pending connection attempts can be canceled by canceling its pending promise like so:
+
+```php
+$promise = $connector->connect($uri);
+
+$promise->cancel();
+```
+
+Calling `cancel()` on a pending promise will cancel the underlying TCP/IP
+connection to the SOCKS server and/or the SOCKS protocol negotiation and reject
+the resulting promise.
+
+#### Secure TLS connections
+
+If you want to establish a secure TLS connection (such as HTTPS) between you and
+your destination, you may want to wrap this connector in React's
+[`Connector`](https://github.com/reactphp/socket#connector) or the low-level
+[`SecureConnector`](https://github.com/reactphp/socket#secureconnector):
+
+```php
+$connector = new React\Socket\Connector($loop, array(
+    'tcp' => $client,
+    'dns' => false
+));
+
+// now create an SSL encrypted connection (notice the $ssl instead of $tcp)
+$connector->connect('tls://www.google.com:443')->then(function (ConnectionInterface $stream) {
+    // proceed with just the plain text data
+    // everything is encrypted/decrypted automatically
+    echo 'connected to SSL encrypted www.google.com';
+    $stream->write("GET / HTTP/1.0\r\n\r\n");
+    // ...
+});
+```
+
+See also the [second example](examples).
+
+If you use the low-level `SecureConnector`, then the `tls://` scheme can also
+be omitted.
+Passing any other scheme will reject the promise.
+
+Pending connection attempts can be canceled by canceling its pending promise
+as usual.
+
+> Also note how secure TLS connections are in fact entirely handled outside of
+  this SOCKS client implementation.
+
+You can optionally pass additional
+[SSL context options](http://php.net/manual/en/context.ssl.php)
+to the constructor like this:
+
+```php
+$connector = new React\Socket\Connector($loop, array(
+    'tcp' => $client,
+    'tls' => array(
+        'verify_peer' => false,
+        'verify_peer_name' => false
+    ),
+    'dns' => false
+));
+```
+
+#### HTTP requests
+
+HTTP operates on a higher layer than this low-level SOCKS implementation.
+If you want to issue HTTP requests, you can add a dependency for
+[clue/buzz-react](https://github.com/clue/php-buzz-react).
+It can interact with this library by issuing all
+[http requests through a SOCKS server](https://github.com/clue/php-buzz-react#socks-proxy).
+This works for both plain HTTP and SSL encrypted HTTPS requests.
+
+#### Protocol version
+
+This library supports the SOCKS4, SOCKS4a and SOCKS5 protocol versions.
+
+While SOCKS4 already had (a somewhat limited) support for `SOCKS BIND` requests
+and SOCKS5 added generic UDP support (`SOCKS UDPASSOCIATE`), this library
+focuses on the most commonly used core feature of `SOCKS CONNECT`.
+In this mode, a SOCKS server acts as a generic proxy allowing higher level
+application protocols to work through it.

+  </tr>
+</table>
+
+Note, this is __not__ a full SOCKS5 implementation due to missing GSSAPI
+authentication (but it's unlikely you're going to miss it anyway).
+
+By default, the `Client` communicates via SOCKS4a with the SOCKS server
+– unless you enable [authentication](#authentication), in which case it will
+default to SOCKS5.
+This is done because SOCKS4a incurs less overhead than SOCKS5 (see above) and
+is equivalent with SOCKS4 if you use [local DNS resolution](#dns-resolution).
+
+If want to explicitly set the protocol version, use the supported values URI
+schemes `socks4`, `socks4a` or `socks5` as part of the SOCKS URI:
+
+```php
+$client = new Client('socks5://127.0.0.1', $connector);
+```
+
+As seen above, both SOCKS5 and SOCKS4a support remote and local DNS resolution.
+If you've explicitly set this to SOCKS4, then you may want to check the following
+chapter about local DNS resolution or you may only connect to IPv4 addresses.
+
+#### DNS resolution
+
+By default, the `Client` does not perform any DNS resolution at all and simply
+forwards any hostname you're trying to connect to to the SOCKS server.
+The remote SOCKS server is thus responsible for looking up any hostnames via DNS
+(this default mode is thus called *remote DNS resolution*).
+As seen above, this mode is supported by the SOCKS5 and SOCKS4a protocols, but
+not the SOCKS4 protocol, as the protocol lacks a way to communicate hostnames.
+
+On the other hand, all SOCKS protocol versions support sending destination IP
+addresses to the SOCKS server.
+In this mode you either have to stick to using IPs only (which is ofen unfeasable)
+or perform any DNS lookups locally and only transmit the resolved destination IPs
+(this mode is thus called *local DNS resolution*).
+
+The default *remote DNS resolution* is useful if your local `Client` either can
+not resolve target hostnames because it has no direct access to the internet or
+if it should not resolve target hostnames because its outgoing DNS traffic might
+be intercepted (in particular when using the
+[Tor network](#using-the-tor-anonymity-network-to-tunnel-socks-connections)).
+
+As noted above, the `Client` defaults to using remote DNS resolution.
+However, wrapping the `Client` in React's
+[`Connector`](https://github.com/reactphp/socket#connector) actually
+performs local DNS resolution unless explicitly defined otherwise.
+Given that remote DNS resolution is assumed to be the preferred mode, all
+other examples explicitly disable DNS resoltion like this:
+
+```php
+$connector = new React\Socket\Connector($loop, array(
+    'tcp' => $client,
+    'dns' => false
+));
+```
+
+If you want to explicitly use *local DNS resolution* (such as when explicitly
+using SOCKS4), you can use the following code:
+
+```php
+// set up Connector which uses Google's public DNS (8.8.8.8)
+$connector = new React\Socket\Connector($loop, array(
+    'tcp' => $client,
+    'dns' => '8.8.8.8'
+));
+```
+
+See also the [fourth example](examples).
+
+Pending connection attempts can be canceled by canceling its pending promise
+as usual.
+
+> Also note how local DNS resolution is in fact entirely handled outside of this
+  SOCKS client implementation.
+
+If you've explicitly set the client to SOCKS4 and stick to the default
+*remote DNS resolution*, then you may only connect to IPv4 addresses because
+the protocol lacks a way to communicate hostnames.
+If you try to connect to a hostname despite, the resulting promise will be
+rejected right away.
+
+#### Authentication
+
+This library supports username/password authentication for SOCKS5 servers as
+defined in [RFC 1929](http://tools.ietf.org/html/rfc1929).
+
+On the client side, simply pass your username and password to use for
+authentication (see below).
+For each further connection the client will merely send a flag to the server
+indicating authentication information is available.
+Only if the server requests authentication during the initial handshake,
+the actual authentication credentials will be transmitted to the server.
+
+Note that the password is transmitted in cleartext to the SOCKS proxy server,
+so this methods should not be used on a network where you have to worry about eavesdropping.
+
+You can simply pass the authentication information as part of the SOCKS URI:
+
+```php
+$client = new Client('username:password@127.0.0.1', $connector);
+```
+
+Note that both the username and password must be percent-encoded if they contain
+special characters:
+
+```php
+$user = 'he:llo';
+$pass = 'p@ss';
+
+$client = new Client(
+    rawurlencode($user) . ':' . rawurlencode($pass) . '@127.0.0.1',
+    $connector
+);
+```
+
+> The authentication details will be transmitted in cleartext to the SOCKS proxy
+  server only if it requires username/password authentication.
+  If the authentication details are missing or not accepted by the remote SOCKS
+  proxy server, it is expected to reject each connection attempt with an
+  exception error code of `SOCKET_EACCES` (13).
+
+Authentication is only supported by protocol version 5 (SOCKS5),
+so passing authentication to the `Client` enforces communication with protocol
+version 5 and complains if you have explicitly set anything else:
+
+```php
+// throws InvalidArgumentException
+new Client('socks4://user:pass@127.0.0.1', $connector);
+```
+
+#### Proxy chaining
+
+The `Client` is responsible for creating connections to the SOCKS server which
+then connects to the target host.
+
+```
+Client -> SocksServer -> TargetHost
+```
+
+Sometimes it may be required to establish outgoing connections via another SOCKS
+server.
+For example, this can be useful if you want to conceal your origin address.
+
+```
+Client -> MiddlemanSocksServer -> TargetSocksServer -> TargetHost
+```
+
+The `Client` uses any instance of the `ConnectorInterface` to establish
+outgoing connections.
+In order to connect through another SOCKS server, you can simply use another
+SOCKS connector from another SOCKS client like this:
+
+```php
+// https via the proxy chain  "MiddlemanSocksServer -> TargetSocksServer -> TargetHost"
+// please note how the client uses TargetSocksServer (not MiddlemanSocksServer!),
+// which in turn then uses MiddlemanSocksServer.
+// this creates a TCP/IP connection to MiddlemanSocksServer, which then connects
+// to TargetSocksServer, which then connects to the TargetHost
+$middle = new Client('127.0.0.1:1080', new Connector($loop));
+$target = new Client('example.com:1080', $middle);
+
+$connector = new React\Socket\Connector($loop, array(
+    'tcp' => $target,
+    'dns' => false
+));
+
+$connector->connect('tls://www.google.com:443')->then(function ($stream) {
+    // …
+});
+```
+
+See also the [third example](examples).
+
+Pending connection attempts can be canceled by canceling its pending promise
+as usual.
+
+Proxy chaining can happen on the server side and/or the client side:
+
+* If you ask your client to chain through multiple proxies, then each proxy
+  server does not really know anything about chaining at all.
+  This means that this is a client-only property.
+
+* If you ask your server to chain through another proxy, then your client does
+  not really know anything about chaining at all.
+  This means that this is a server-only property and not part of this class.
+  For example, you can find this in the below [`Server`](#server-proxy-chaining)
+  class or somewhat similar when you're using the
+  [Tor network](#using-the-tor-anonymity-network-to-tunnel-socks-connections).
+
+#### Connection timeout
+
+By default, the `Client` does not implement any timeouts for establishing remote
+connections.
+Your underlying operating system may impose limits on pending and/or idle TCP/IP
+connections, anywhere in a range of a few minutes to several hours.
+
+Many use cases require more control over the timeout and likely values much
+smaller, usually in the range of a few seconds only.
+
+You can use React's [`Connector`](https://github.com/reactphp/socket#connector)
+or the low-level
+[`TimeoutConnector`](https://github.com/reactphp/socket#timeoutconnector)
+to decorate any given `ConnectorInterface` instance.
+It provides the same `connect()` method, but will automatically reject the
+underlying connection attempt if it takes too long:
+
+```php
+$connector = new Connector($loop, array(
+    'tcp' => $client,
+    'dns' => false,
+    'timeout' => 3.0
+));
+
+$connector->connect('tcp://google.com:80')->then(function ($stream) {
+    // connection succeeded within 3.0 seconds
+});
+```
+
+See also any of the [examples](examples).
+
+Pending connection attempts can be canceled by canceling its pending promise
+as usual.
+
+> Also note how connection timeout is in fact entirely handled outside of this
+  SOCKS client implementation.
+
+#### SOCKS over TLS
+
+All [SOCKS protocol versions](#protocol-version) support forwarding TCP/IP
+based connections and higher level protocols.
+This implies that you can also use [secure TLS connections](#secure-tls-connections)
+to transfer sensitive data across SOCKS proxy servers.
+This means that no eavesdropper nor the proxy server will be able to decrypt
+your data.
+
+However, the initial SOCKS communication between the client and the proxy is
+usually via an unencrypted, plain TCP/IP connection.
+This means that an eavesdropper may be able to see *where* you connect to and
+may also be able to see your [SOCKS authentication](#authentication) details
+in cleartext.
+
+As an alternative, you may establish a secure TLS connection to your SOCKS
+proxy before starting the initial SOCKS communication.
+This means that no eavesdroppper will be able to see the destination address
+you want to connect to or your [SOCKS authentication](#authentication) details.
+
+You can use the `sockss://` URI scheme or use an explicit
+[SOCKS protocol version](#protocol-version) like this:
+
+```php
+$client = new Client('sockss://127.0.0.1:1080', new Connector($loop));
+
+$client = new Client('socks5s://127.0.0.1:1080', new Connector($loop));
+```
+
+See also [example 32](examples).
+
+Simiarly, you can also combine this with [authentication](#authentication)
+like this:
+
+```php
+$client = new Client('sockss://user:pass@127.0.0.1:1080', new Connector($loop));
+```
+
+> Note that for most use cases, [secure TLS connections](#secure-tls-connections)
+  should be used instead. SOCKS over TLS is considered advanced usage and is
+  used very rarely in practice.
+  In particular, the SOCKS server has to accept secure TLS connections, see
+  also [Server SOCKS over TLS](#server-socks-over-tls) for more details.
+  Also, PHP does not support "double encryption" over a single connection.
+  This means that enabling [secure TLS connections](#secure-tls-connections)
+  over a communication channel that has been opened with SOCKS over TLS
+  may not be supported.
+
+> Note that the SOCKS protocol does not support the notion of TLS. The above
+  works reasonably well because TLS is only used for the connection between
+  client and proxy server and the SOCKS protocol data is otherwise identical.
+  This implies that this may also have only limited support for
+  [proxy chaining](#proxy-chaining) over multiple TLS paths.
+
+#### Unix domain sockets
+
+All [SOCKS protocol versions](#protocol-version) support forwarding TCP/IP
+based connections and higher level protocols.
+In some advanced cases, it may be useful to let your SOCKS server listen on a
+Unix domain socket (UDS) path instead of a IP:port combination.
+For example, this allows you to rely on file system permissions instead of
+having to rely on explicit [authentication](#authentication).
+
+You can use the `socks+unix://` URI scheme or use an explicit
+[SOCKS protocol version](#protocol-version) like this:
+
+```php
+$client = new Client('socks+unix:///tmp/proxy.sock', new Connector($loop));
+
+$client = new Client('socks5+unix:///tmp/proxy.sock', new Connector($loop));
+```
+
+Simiarly, you can also combine this with [authentication](#authentication)
+like this:
+
+```php
+$client = new Client('socks+unix://user:pass@/tmp/proxy.sock', new Connector($loop));
+```
+
+> Note that Unix domain sockets (UDS) are considered advanced usage and PHP only
+  has limited support for this.
+  In particular, enabling [secure TLS](#secure-tls-connections) may not be
+  supported.
+
+> Note that SOCKS protocol does not support the notion of UDS paths. The above
+  works reasonably well because UDS is only used for the connection between
+  client and proxy server and the path will not actually passed over the protocol.
+  This implies that this does also not support [proxy chaining](#proxy-chaining)
+  over multiple UDS paths.
+
+### Server
+
+The `Server` is responsible for accepting incoming communication from SOCKS clients
+and forwarding the requested connection to the target host.
+It also registers everything with the main [`EventLoop`](https://github.com/reactphp/event-loop#usage)
+and an underlying TCP/IP socket server like this:
+
+```php
+$loop = \React\EventLoop\Factory::create();
+
+// listen on localhost:$port
+$socket = new Socket($port, $loop);
+
+$server = new Server($loop, $socket);
+```
+
+#### Server connector
+
+The `Server` uses an instance of the [`ConnectorInterface`](#connectorinterface)
+to establish outgoing connections for each incoming connection request.
+
+If you need custom connector settings (DNS resolution, timeouts etc.), you can explicitly pass a
+custom instance of the [`ConnectorInterface`](https://github.com/reactphp/socket#connectorinterface):
+
+```php
+// use local DNS server
+$dnsResolverFactory = new DnsFactory();
+$resolver = $dnsResolverFactory->createCached('127.0.0.1', $loop);
+
+// outgoing connections to target host via interface 192.168.10.1
+$connector = new DnsConnector(
+    new TcpConnector($loop, array('bindto' => '192.168.10.1:0')),
+    $resolver
+);
+
+$server = new Server($loop, $socket, $connector);
+```
+
+If you want to forward the outgoing connection through another SOCKS proxy, you
+may also pass a [`Client`](#client) instance as a connector, see also
+[server proxy chaining](#server-proxy-chaining) for more details.
+
+Internally, the `Server` uses the normal [`connect()`](#connect) method, but
+it also passes the original client IP as the `?source={remote}` parameter.
+The `source` parameter contains the full remote URI, including the protocol
+and any authentication details, for example `socks5://user:pass@1.2.3.4:5678`.
+You can use this parameter for logging purposes or to restrict connection
+requests for certain clients by providing a custom implementation of the
+[`ConnectorInterface`](#connectorinterface).
+
+#### Server protocol version
+
+The `Server` supports all protocol versions (SOCKS4, SOCKS4a and SOCKS5) by default.
+
+If want to explicitly set the protocol version, use the supported values `4`, `4a` or `5`:
+
+```PHP
+$server->setProtocolVersion(5);
+```
+
+In order to reset the protocol version to its default (i.e. automatic detection),
+use `null` as protocol version.
+
+```PHP
+$server->setProtocolVersion(null);
+```
+
+#### Server authentication
+
+By default, the `Server` does not require any authentication from the clients.
+You can enable authentication support so that clients need to pass a valid
+username and password before forwarding any connections.
+
+Setting authentication on the `Server` enforces each further connected client
+to use protocol version 5 (SOCKS5).
+If a client tries to use any other protocol version, does not send along
+authentication details or if authentication details can not be verified,
+the connection will be rejected.
+
+Because your authentication mechanism might take some time to actually check
+the provided authentication credentials (like querying a remote database or webservice),
+the server side uses a [Promise](https://github.com/reactphp/promise) based interface.
+While this might seem complex at first, it actually provides a very simple way
+to handle simultanous connections in a non-blocking fashion and increases overall performance.
+
+```PHP
+$server->setAuth(function ($username, $password, $remote) {
+    // either return a boolean success value right away
+    // or use promises for delayed authentication
+
+    // $remote is a full URI à la socks5://user:pass@192.168.1.1:1234
+    // or socks5s://user:pass@192.168.1.1:1234 for SOCKS over TLS
+    // useful for logging or extracting parts, such as the remote IP
+    $ip = parse_url($remote, PHP_URL_HOST);
+
+    return ($username === 'root' && $ip === '127.0.0.1');
+});
+```
+
+Or if you only accept static authentication details, you can use the simple
+array-based authentication method as a shortcut:
+
+```PHP
+$server->setAuthArray(array(
+    'tom' => 'password',
+    'admin' => 'root'
+));
+```
+
+See also [example #12](examples).
+
+If you do not want to use authentication anymore:
+
+```PHP
+$server->unsetAuth();
+```
+
+#### Server proxy chaining
+
+The `Server` is responsible for creating connections to the target host.
+
+```
+Client -> SocksServer -> TargetHost
+```
+
+Sometimes it may be required to establish outgoing connections via another SOCKS
+server.
+For example, this can be useful if your target SOCKS server requires
+authentication, but your client does not support sending authentication
+information (e.g. like most webbrowser).
+
+```
+Client -> MiddlemanSocksServer -> TargetSocksServer -> TargetHost
+```
+
+The `Server` uses any instance of the `ConnectorInterface` to establish outgoing
+connections.
+In order to connect through another SOCKS server, you can simply use the
+[`Client`](#client) SOCKS connector from above.
+You can create a SOCKS `Client` instance like this: 
+
+```php
+// set next SOCKS server example.com:1080 as target
+$connector = new React\Socket\Connector($loop);
+$client = new Client('user:pass@example.com:1080', $connector);
+
+// listen on localhost:1080
+$socket = new Socket('127.0.0.1:1080', $loop);
+
+// start a new server which forwards all connections to the other SOCKS server
+$server = new Server($loop, $socket, $client);
+```
+
+See also [example #21](examples).
+
+Proxy chaining can happen on the server side and/or the client side:
+
+* If you ask your client to chain through multiple proxies, then each proxy
+  server does not really know anything about chaining at all.
+  This means that this is a client-only property and not part of this class.
+  For example, you can find this in the above [`Client`](#proxy-chaining) class.
+
+* If you ask your server to chain through another proxy, then your client does
+  not really know anything about chaining at all.
+  This means that this is a server-only property and can be implemented as above.
+
+#### Server SOCKS over TLS
+
+All [SOCKS protocol versions](#server-protocol-version) support forwarding TCP/IP
+based connections and higher level protocols.
+This implies that you can also use [secure TLS connections](#secure-tls-connections)
+to transfer sensitive data across SOCKS proxy servers.
+This means that no eavesdropper nor the proxy server will be able to decrypt
+your data.
+
+However, the initial SOCKS communication between the client and the proxy is
+usually via an unencrypted, plain TCP/IP connection.
+This means that an eavesdropper may be able to see *where* the client connects
+to and may also be able to see the [SOCKS authentication](#authentication)
+details in cleartext.
+
+As an alternative, you may listen for SOCKS over TLS connections so
+that the client has to establish a secure TLS connection to your SOCKS
+proxy before starting the initial SOCKS communication.
+This means that no eavesdroppper will be able to see the destination address
+the client wants to connect to or their [SOCKS authentication](#authentication)
+details.
+
+You can simply start your listening socket on the `tls://` URI scheme like this:
+
+```php
+$loop = \React\EventLoop\Factory::create();
+
+// listen on tls://127.0.0.1:1080 with the given server certificate
+$socket = new React\Socket\Server('tls://127.0.0.1:1080', $loop, array(
+    'tls' => array(
+        'local_cert' => __DIR__ . '/localhost.pem',
+    )
+));
+$server = new Server($loop, $socket);
+```
+
+See also [example 31](examples).
+
+> Note that for most use cases, [secure TLS connections](#secure-tls-connections)
+  should be used instead. SOCKS over TLS is considered advanced usage and is
+  used very rarely in practice.
+
+> Note that the SOCKS protocol does not support the notion of TLS. The above
+  works reasonably well because TLS is only used for the connection between
+  client and proxy server and the SOCKS protocol data is otherwise identical.
+  This implies that this does also not support [proxy chaining](#server-proxy-chaining)
+  over multiple TLS paths.
+
+#### Server Unix domain sockets
+
+All [SOCKS protocol versions](#server-protocol-version) support forwarding TCP/IP
+based connections and higher level protocols.
+In some advanced cases, it may be useful to let your SOCKS server listen on a
+Unix domain socket (UDS) path instead of a IP:port combination.
+For example, this allows you to rely on file system permissions instead of
+having to rely on explicit [authentication](#server-authentication).
+
+You can simply start your listening socket on the `unix://` URI scheme like this:
+
+```php
+$loop = \React\EventLoop\Factory::create();
+
+// listen on /tmp/proxy.sock
+$socket = new React\Socket\Server('unix:///tmp/proxy.sock', $loop);
+$server = new Server($loop, $socket);
+```
+
+> Note that Unix domain sockets (UDS) are considered advanced usage and that
+  the SOCKS protocol does not support the notion of UDS paths. The above
+  works reasonably well because UDS is only used for the connection between
+  client and proxy server and the path will not actually passed over the protocol.
+  This implies that this does also not support [proxy chaining](#server-proxy-chaining)
+  over multiple UDS paths.
+
+## Servers
+
+### Using a PHP SOCKS server
+
+* If you're looking for an end-user SOCKS server daemon, you may want to use
+  [LeProxy](https://leproxy.org/) or [clue/psocksd](https://github.com/clue/psocksd).
+* If you're looking for a SOCKS server implementation, consider using
+  the above [`Server`](#server) class.
+
+### Using SSH as a SOCKS server
+
+If you already have an SSH server set up, you can easily use it as a SOCKS
+tunnel end point. On your client, simply start your SSH client and use
+the `-D <port>` option to start a local SOCKS server (quoting the man page:
+a `local "dynamic" application-level port forwarding`).
+
+You can start a local SOCKS server by creating a loopback connection to your
+local system if you already run an SSH daemon:
+
+```bash
+$ ssh -D 1080 localhost
+```
+
+Alternatively, you can start a local SOCKS server tunneling through a given
+remote host that runs an SSH daemon:
+
+```bash
+$ ssh -D 1080 example.com
+```
+
+Now you can simply use this SSH SOCKS server like this:
+
+```PHP
+$client = new Client('127.0.0.1:1080', $connector);
+```
+
+Note that the above will allow all users on the local system to connect over
+your SOCKS server without authentication which may or may not be what you need.
+As an alternative, recent OpenSSH client versions also support
+[Unix domain sockets](#unix-domain-sockets) (UDS) paths so that you can rely
+on Unix file system permissions instead:
+
+```bash
+$ ssh -D/tmp/proxy.sock example.com
+```
+
+Now you can simply use this SSH SOCKS server like this:
+
+```PHP
+$client = new Client('socks+unix:///tmp/proxy.sock', $connector);
+```
+
+### Using the Tor (anonymity network) to tunnel SOCKS connections
+
+The [Tor anonymity network](http://www.torproject.org) client software is designed
+to encrypt your traffic and route it over a network of several nodes to conceal its origin.
+It presents a SOCKS4 and SOCKS5 interface on TCP port 9050 by default
+which allows you to tunnel any traffic through the anonymity network.
+In most scenarios you probably don't want your client to resolve the target hostnames,
+because you would leak DNS information to anybody observing your local traffic.
+Also, Tor provides hidden services through an `.onion` pseudo top-level domain
+which have to be resolved by Tor.
+
+```PHP
+$client = new Client('127.0.0.1:9050', $connector);
+```
+
+## Install

+
+This will install the latest supported version:
+
+```bash
+$ composer require clue/socks-react:^0.8.7
+```
+
+See also the [CHANGELOG](CHANGELOG.md) for details about version upgrades.
+
+## Tests
+
+To run the test suite, you first need to clone this repo and then install all
+dependencies [through Composer](https://getcomposer.org):
+
+```bash
+$ composer install
+```
+
+To run the test suite, go to the project root and run:
+
+```bash
+$ php vendor/bin/phpunit
+```

+* As an alternative to a SOCKS (SOCKS4/SOCKS5) proxy, you may also want to look into
+  using an HTTP CONNECT proxy instead.
+  You may want to use [clue/http-proxy-react](https://github.com/clue/php-http-proxy-react)
+  which also provides an implementation of the
+  [`ConnectorInterface`](#connectorinterface) so that supporting either proxy
+  protocol should be fairly trivial.
+* If you're dealing with public proxies, you'll likely have to work with mixed
+  quality and unreliable proxies. You may want to look into using
+  [clue/connection-manager-extra](https://github.com/clue/php-connection-manager-extra)
+  which allows retrying unreliable ones, implying connection timeouts,
+  concurrently working with multiple connectors and more.
+* If you're looking for an end-user SOCKS server daemon, you may want to use
+  [LeProxy](https://leproxy.org/) or [clue/psocksd](https://github.com/clue/psocksd).

+## Synopsis
+
+```php
+use GetOptionKit\OptionCollection;
+use GetOptionKit\OptionParser;
+use GetOptionKit\OptionPrinter\ConsoleOptionPrinter;
+
+$specs = new OptionCollection;
+$specs->add('f|foo:', 'option requires a value.' )
+    ->isa('String');

+    ->isa('Number');
+
+$specs->add('ip+', 'Ip constraint' )

+
+$specs->add('email+', 'Email address constraint' )
+    ->isa('Email');
+

+    ->isa('Boolean');
+
+$specs->add('file:', 'option value should be a file.' )
+    ->isa('File');
+

+    }
+
+    $opt = $result->keys['foo']; // return the option object.

+}
+```
+
+
+## Documentation
+
+See <https://github.com/c9s/GetOptionKit/wiki> for more details.
+
+### Option Value Type
+
+The option value type help you validate the input,
+the following list is the current supported types:
+
+- `string`
+- `number`
+- `boolean`
+- `file`
+- `date`
+- `url`
+- `email`
+- `ip`
+- `ipv4`
+- `ipv6`
+- `regex`
+
+And here is the related sample code:
+
+```php
+$opt->add( 'f|foo:' , 'with string type value' )
+    ->isa('string');
+
+$opt->add( 'b|bar+' , 'with number type value' )
+    ->isa('number');
+
+$opt->add( 'z|zoo?' , 'with boolean type value' )
+    ->isa('boolean');
+
+$opt->add( 'file:' , 'with file type value' )
+    ->isa('file');
+
+$opt->add( 'date:' , 'with date type value' )
+    ->isa('date');
+
+$opt->add( 'url:' , 'with url type value' )
+    ->isa('url');
+
+$opt->add( 'email:' , 'with email type value' )
+    ->isa('email');
+
+$opt->add( 'ip:' , 'with ip(v4/v6) type value' )
+    ->isa('ip');
+
+$opt->add( 'ipv4:' , 'with ipv4 type value' )
+    ->isa('ipv4');
+
+$opt->add( 'ipv6:' , 'with ipv6 type value' )
+    ->isa('ipv6');
+
+$specs->add('r|regex:', 'with custom regex type value')
+      ->isa('Regex', '/^([a-z]+)$/');
+```
+
+> Please note that currently only `string`, `number`, `boolean` types can be validated.
+
+### ContinuousOptionParser
+
+```php
+$specs = new OptionCollection;
+$spec_verbose = $specs->add('v|verbose');
+$spec_color = $specs->add('c|color');
+$spec_debug = $specs->add('d|debug');
+$spec_verbose->description = 'verbose flag';
+
+// ContinuousOptionParser
+$parser = new ContinuousOptionParser( $specs );
+$result = $parser->parse(explode(' ','program -v -d test -a -b -c subcommand -e -f -g subcommand2'));
+$result2 = $parser->continueParse();
+```
+
+### OptionPrinter
+
+GetOptionKit\OptionPrinter can print options for you:
+
+    * Available options:
+                  -f, --foo   option requires a value.
+                  -b, --bar   option with multiple value.
+                  -z, --zoo   option with optional value.
+              -v, --verbose   verbose message.
+                -d, --debug   debug message.
+                     --long   long option name only.
+                         -s   short option name only.
+
+
+## Command-line app with subcommands
+
+For application with subcommands is designed by following form:
+
+
+    [app name] [app opts] 
+                 [subcommand1] [subcommand-opts]
+                 [subcommand2] [subcommand-opts]
+                 [subcommand3] [subcommand-opts]
+                 [arguments]
+
+You can check the `tests/GetOptionKit/ContinuousOptionParserTest.php` unit test file:
+
+```php
+// subcommand stack
+$subcommands = array('subcommand1','subcommand2','subcommand3');
+
+// different command has its own options
+$subcommandSpecs = array(
+    'subcommand1' => $cmdspecs,
+    'subcommand2' => $cmdspecs,
+    'subcommand3' => $cmdspecs,
+);
+
+// for saved options
+$subcommandOptions = array();
+
+// command arguments
+$arguments = array();
+
+$argv = explode(' ','program -v -d -c subcommand1 -a -b -c subcommand2 -c subcommand3 arg1 arg2 arg3');
+
+// parse application options first
+$parser = new ContinuousOptionParser( $appspecs );
+$app_options = $parser->parse( $argv );
+while (! $parser->isEnd()) {
+    if (@$subcommands[0] && $parser->getCurrentArgument() == $subcommands[0]) {
+        $parser->advance();
+        $subcommand = array_shift( $subcommands );
+        $parser->setSpecs( $subcommandSpecs[$subcommand] );
+        $subcommandOptions[ $subcommand ] = $parser->continueParse();
+    } else {
+        $arguments[] = $parser->advance();
+    }
+}
+```
+
+## Todo
+
+* Option Spec group.
+* option valid value checking.
+* custom command mapping.
+
+## Command Line Utility Design Concept
+
+* main program name should be easy to type, easy to remember.
+* subcommand should be easy to type, easy to remember. length should be shorter than 7 characters.
+* options should always have long descriptive name
+* a program should be easy to check usage.
+
+## General command interface
+
+To list usage of all subcommands or the program itself:
+
+	$ prog help
+
+To list the subcommand usage
+
+	$ prog help subcommand subcommand2 subcommand3

+# Événement
+
+Événement is a very simple event dispatching library for PHP.
+
+It has the same design goals as [Silex](http://silex-project.org) and
+[Pimple](http://pimple-project.org), to empower the user while staying concise
+and simple.
+
+It is very strongly inspired by the EventEmitter API found in
+[node.js](http://nodejs.org).
+
+[![Build Status](https://secure.travis-ci.org/igorw/evenement.png?branch=master)](http://travis-ci.org/igorw/evenement)
+
+## Fetch
+
+The recommended way to install Événement is [through composer](http://getcomposer.org).
+
+Just create a composer.json file for your project:
+
+```JSON
+{
+    "require": {
+        "evenement/evenement": "^3.0 || ^2.0"
+    }
+}
+```
+
+**Note:** The `3.x` version of Événement requires PHP 7 and the `2.x` version requires PHP 5.4. If you are
+using PHP 5.3, please use the `1.x` version:
+
+```JSON
+{
+    "require": {
+        "evenement/evenement": "^1.0"
+    }
+}
+```
+
+And run these two commands to install it:
+
+    $ curl -s http://getcomposer.org/installer | php
+    $ php composer.phar install
+
+Now you can add the autoloader, and you will have access to the library:
+
+```php
+<?php
+require 'vendor/autoload.php';
+```
+
+## Usage
+
+### Creating an Emitter
+
+```php
+<?php
+$emitter = new Evenement\EventEmitter();
+```
+
+### Adding Listeners
+
+```php
+<?php
+$emitter->on('user.created', function (User $user) use ($logger) {
+    $logger->log(sprintf("User '%s' was created.", $user->getLogin()));
+});
+```
+
+### Emitting Events
+
+```php
+<?php
+$emitter->emit('user.created', [$user]);
+```
+

+# Introduction
+
+Événement is is French and means "event". The événement library aims to
+provide a simple way of subscribing to events and notifying those subscribers
+whenever an event occurs.
+
+The API that it exposes is almost a direct port of the EventEmitter API found
+in node.js. It also includes an "EventEmitter". There are some minor
+differences however.
+
+The EventEmitter is an implementation of the publish-subscribe pattern, which
+is a generalized version of the observer pattern. The observer pattern
+specifies an observable subject, which observers can register themselves to.
+Once something interesting happens, the subject notifies its observers.
+
+Pub/sub takes the same idea but encapsulates the observation logic inside a
+separate object which manages all of its subscribers or listeners. Subscribers
+are bound to an event name, and will only receive notifications of the events
+they subscribed to.
+
+**TLDR: What does evenement do, in short? It provides a mapping from event
+names to a list of listener functions and triggers each listener for a given
+event when it is emitted.**
+
+Why do we do this, you ask? To achieve decoupling.
+
+It allows you to design a system where the core will emit events, and modules
+are able to subscribe to these events. And respond to them.

+# API
+
+The API that événement exposes is defined by the
+`Evenement\EventEmitterInterface`. The interface is useful if you want to
+define an interface that extends the emitter and implicitly defines certain
+events to be emitted, or if you want to type hint an `EventEmitter` to be
+passed to a method without coupling to the specific implementation.
+
+## on($event, callable $listener)
+
+Allows you to subscribe to an event.
+
+Example:
+
+```php
+$emitter->on('user.created', function (User $user) use ($logger) {
+    $logger->log(sprintf("User '%s' was created.", $user->getLogin()));
+});
+```
+
+Since the listener can be any callable, you could also use an instance method
+instead of the anonymous function:
+
+```php
+$loggerSubscriber = new LoggerSubscriber($logger);
+$emitter->on('user.created', array($loggerSubscriber, 'onUserCreated'));
+```
+
+This has the benefit that listener does not even need to know that the emitter
+exists.
+
+You can also accept more than one parameter for the listener:
+
+```php
+$emitter->on('numbers_added', function ($result, $a, $b) {});
+```
+
+## once($event, callable $listener)
+
+Convenience method that adds a listener which is guaranteed to only be called
+once.
+
+Example:
+
+```php
+$conn->once('connected', function () use ($conn, $data) {
+    $conn->send($data);
+});
+```
+
+## emit($event, array $arguments = [])
+
+Emit an event, which will call all listeners.
+
+Example:
+
+```php
+$conn->emit('data', [$data]);
+```
+
+The second argument to emit is an array of listener arguments. This is how you
+specify more args:
+
+```php
+$result = $a + $b;
+$emitter->emit('numbers_added', [$result, $a, $b]);
+```
+
+## listeners($event)
+
+Allows you to inspect the listeners attached to an event. Particularly useful
+to check if there are any listeners at all.
+
+Example:
+
+```php
+$e = new \RuntimeException('Everything is broken!');
+if (0 === count($emitter->listeners('error'))) {
+    throw $e;
+}
+```
+
+## removeListener($event, callable $listener)
+
+Remove a specific listener for a specific event.
+
+## removeAllListeners($event = null)
+
+Remove all listeners for a specific event or all listeners all together. This
+is useful for long-running processes, where you want to remove listeners in
+order to allow them to get garbage collected.

+# Example: Plugin system
+
+In this example I will show you how to create a generic plugin system with
+événement where plugins can alter the behaviour of the app. The app is a blog.
+Boring, I know. By using the EventEmitter it will be easy to extend this blog
+with additional functionality without modifying the core system.
+
+The blog is quite basic. Users are able to create blog posts when they log in.
+The users are stored in a static config file, so there is no sign up process.
+Once logged in they get a "new post" link which gives them a form where they
+can create a new blog post with plain HTML. That will store the post in a
+document database. The index lists all blog post titles by date descending.
+Clicking on the post title will take you to the full post.
+
+## Plugin structure
+
+The goal of the plugin system is to allow features to be added to the blog
+without modifying any core files of the blog.
+
+The plugins are managed through a config file, `plugins.json`. This JSON file
+contains a JSON-encoded list of class-names for plugin classes. This allows
+you to enable and disable plugins in a central location. The initial
+`plugins.json` is just an empty array:
+```json
+[]
+```
+
+A plugin class must implement the `PluginInterface`:
+```php
+interface PluginInterface
+{
+    function attachEvents(EventEmitterInterface $emitter);
+}
+```
+
+The `attachEvents` method allows the plugin to attach any events to the
+emitter. For example:
+```php
+class FooPlugin implements PluginInterface
+{
+    public function attachEvents(EventEmitterInterface $emitter)
+    {
+        $emitter->on('foo', function () {
+            echo 'bar!';
+        });
+    }
+}
+```
+
+The blog system creates an emitter instance and loads the plugins:
+```php
+$emitter = new EventEmitter();
+
+$pluginClasses = json_decode(file_get_contents('plugins.json'), true);
+foreach ($pluginClasses as $pluginClass) {
+    $plugin = new $pluginClass();
+    $pluginClass->attachEvents($emitter);
+}
+```
+
+This is the base system. There are no plugins yet, and there are no events yet
+either. That's because I don't know which extension points will be needed. I
+will add them on demand.
+
+## Feature: Markdown
+
+Writing blog posts in HTML sucks! Wouldn't it be great if I could write them
+in a nice format such as markdown, and have that be converted to HTML for me?
+
+This feature will need two extension points. I need to be able to mark posts
+as markdown, and I need to be able to hook into the rendering of the post body
+and convert it from markdown to HTML. So the blog needs two new events:
+`post.create` and `post.render`.
+
+In the code that creates the post, I'll insert the `post.create` event:
+```php
+class PostEvent
+{
+    public $post;
+
+    public function __construct(array $post)
+    {
+        $this->post = $post;
+    }
+}
+
+$post = createPostFromRequest($_POST);
+
+$event = new PostEvent($post);
+$emitter->emit('post.create', [$event]);
+$post = $event->post;
+
+$db->save('post', $post);
+```
+
+This shows that you can wrap a value in an event object to make it mutable,
+allowing listeners to change it.
+
+The same thing for the `post.render` event:
+```php
+public function renderPostBody(array $post)
+{
+    $emitter = $this->emitter;
+
+    $event = new PostEvent($post);
+    $emitter->emit('post.render', [$event]);
+    $post = $event->post;
+
+    return $post['body'];
+}
+
+<h1><?= $post['title'] %></h1>
+<p><?= renderPostBody($post) %></p>
+```
+
+Ok, the events are in place. It's time to create the first plugin, woohoo! I
+will call this the `MarkdownPlugin`, so here's `plugins.json`:
+```json
+[
+    "MarkdownPlugin"
+]
+```
+
+The `MarkdownPlugin` class will be autoloaded, so I don't have to worry about
+including any files. I just have to worry about implementing the plugin class.
+The `markdown` function represents a markdown to HTML converter.
+```php
+class MarkdownPlugin implements PluginInterface
+{
+    public function attachEvents(EventEmitterInterface $emitter)
+    {
+        $emitter->on('post.create', function (PostEvent $event) {
+            $event->post['format'] = 'markdown';
+        });
+
+        $emitter->on('post.render', function (PostEvent $event) {
+            if (isset($event->post['format']) && 'markdown' === $event->post['format']) {
+                $event->post['body'] = markdown($event->post['body']);
+            }
+        });
+    }
+}
+```
+
+There you go, the blog now renders posts as markdown. But all of the previous
+posts before the addition of the markdown plugin are still rendered correctly
+as raw HTML.

+## 6.0.2 - 2015-07-04
+
+* Fixed a memory leak in the curl handlers in which references to callbacks
+  were not being removed by `curl_reset`.
+* Cookies are now extracted properly before redirects.
+* Cookies now allow more character ranges.
+* Decoded Content-Encoding responses are now modified to correctly reflect
+  their state if the encoding was automatically removed by a handler. This
+  means that the `Content-Encoding` header may be removed an the
+  `Content-Length` modified to reflect the message size after removing the
+  encoding.
+* Added a more explicit error message when trying to use `form_params` and
+  `multipart` in the same request.
+* Several fixes for HHVM support.
+* Functions are now conditionally required using an additional level of
+  indirection to help with global Composer installations.
+
+## 6.0.1 - 2015-05-27
+
+* Fixed a bug with serializing the `query` request option where the `&`
+  separator was missing.
+* Added a better error message for when `body` is provided as an array. Please
+  use `form_params` or `multipart` instead.
+* Various doc fixes.
+
+## 6.0.0 - 2015-05-26
+
+* See the UPGRADING.md document for more information.
+* Added `multipart` and `form_params` request options.
+* Added `synchronous` request option.
+* Added the `on_headers` request option.
+* Fixed `expect` handling.
+* No longer adding default middlewares in the client ctor. These need to be
+  present on the provided handler in order to work.
+* Requests are no longer initiated when sending async requests with the
+  CurlMultiHandler. This prevents unexpected recursion from requests completing
+  while ticking the cURL loop.
+* Removed the semantics of setting `default` to `true`. This is no longer
+  required now that the cURL loop is not ticked for async requests.
+* Added request and response logging middleware.
+* No longer allowing self signed certificates when using the StreamHandler.
+* Ensuring that `sink` is valid if saving to a file.
+* Request exceptions now include a "handler context" which provides handler
+  specific contextual information.
+* Added `GuzzleHttp\RequestOptions` to allow request options to be applied
+  using constants.
+* `$maxHandles` has been removed from CurlMultiHandler.
+* `MultipartPostBody` is now part of the `guzzlehttp/psr7` package.
+
+## 5.3.0 - 2015-05-19
+
+* Mock now supports `save_to`
+* Marked `AbstractRequestEvent::getTransaction()` as public.
+* Fixed a bug in which multiple headers using different casing would overwrite
+  previous headers in the associative array.
+* Added `Utils::getDefaultHandler()`
+* Marked `GuzzleHttp\Client::getDefaultUserAgent` as deprecated.
+* URL scheme is now always lowercased.
+
+## 6.0.0-beta.1
+
+* Requires PHP >= 5.5
+* Updated to use PSR-7
+  * Requires immutable messages, which basically means an event based system
+    owned by a request instance is no longer possible.
+  * Utilizing the [Guzzle PSR-7 package](https://github.com/guzzle/psr7).
+  * Removed the dependency on `guzzlehttp/streams`. These stream abstractions
+    are available in the `guzzlehttp/psr7` package under the `GuzzleHttp\Psr7`
+    namespace.
+* Added middleware and handler system
+  * Replaced the Guzzle event and subscriber system with a middleware system.
+  * No longer depends on RingPHP, but rather places the HTTP handlers directly
+    in Guzzle, operating on PSR-7 messages.
+  * Retry logic is now encapsulated in `GuzzleHttp\Middleware::retry`, which
+    means the `guzzlehttp/retry-subscriber` is now obsolete.
+  * Mocking responses is now handled using `GuzzleHttp\Handler\MockHandler`.
+* Asynchronous responses
+  * No longer supports the `future` request option to send an async request.
+    Instead, use one of the `*Async` methods of a client (e.g., `requestAsync`,
+    `getAsync`, etc.).
+  * Utilizing `GuzzleHttp\Promise` instead of React's promise library to avoid
+    recursion required by chaining and forwarding react promises. See
+    https://github.com/guzzle/promises
+  * Added `requestAsync` and `sendAsync` to send request asynchronously.
+  * Added magic methods for `getAsync()`, `postAsync()`, etc. to send requests
+    asynchronously.
+* Request options
+  * POST and form updates
+    * Added the `form_fields` and `form_files` request options.
+    * Removed the `GuzzleHttp\Post` namespace.
+    * The `body` request option no longer accepts an array for POST requests.
+  * The `exceptions` request option has been deprecated in favor of the
+    `http_errors` request options.
+  * The `save_to` request option has been deprecated in favor of `sink` request
+    option.
+* Clients no longer accept an array of URI template string and variables for
+  URI variables. You will need to expand URI templates before passing them
+  into a client constructor or request method.
+* Client methods `get()`, `post()`, `put()`, `patch()`, `options()`, etc. are
+  now magic methods that will send synchronous requests.
+* Replaced `Utils.php` with plain functions in `functions.php`.
+* Removed `GuzzleHttp\Collection`.
+* Removed `GuzzleHttp\BatchResults`. Batched pool results are now returned as
+  an array.
+* Removed `GuzzleHttp\Query`. Query string handling is now handled using an
+  associative array passed into the `query` request option. The query string
+  is serialized using PHP's `http_build_query`. If you need more control, you
+  can pass the query string in as a string.
+* `GuzzleHttp\QueryParser` has been replaced with the
+  `GuzzleHttp\Psr7\parse_query`.
+
+## 5.2.0 - 2015-01-27
+
+* Added `AppliesHeadersInterface` to make applying headers to a request based
+  on the body more generic and not specific to `PostBodyInterface`.
+* Reduced the number of stack frames needed to send requests.
+* Nested futures are now resolved in the client rather than the RequestFsm
+* Finishing state transitions is now handled in the RequestFsm rather than the
+  RingBridge.
+* Added a guard in the Pool class to not use recursion for request retries.
+
+## 5.1.0 - 2014-12-19
+
+* Pool class no longer uses recursion when a request is intercepted.
+* The size of a Pool can now be dynamically adjusted using a callback.
+  See https://github.com/guzzle/guzzle/pull/943.
+* Setting a request option to `null` when creating a request with a client will
+  ensure that the option is not set. This allows you to overwrite default
+  request options on a per-request basis.
+  See https://github.com/guzzle/guzzle/pull/937.
+* Added the ability to limit which protocols are allowed for redirects by
+  specifying a `protocols` array in the `allow_redirects` request option.
+* Nested futures due to retries are now resolved when waiting for synchronous
+  responses. See https://github.com/guzzle/guzzle/pull/947.
+* `"0"` is now an allowed URI path. See
+  https://github.com/guzzle/guzzle/pull/935.
+* `Query` no longer typehints on the `$query` argument in the constructor,
+  allowing for strings and arrays.
+* Exceptions thrown in the `end` event are now correctly wrapped with Guzzle
+  specific exceptions if necessary.
+
+## 5.0.3 - 2014-11-03
+
+This change updates query strings so that they are treated as un-encoded values
+by default where the value represents an un-encoded value to send over the
+wire. A Query object then encodes the value before sending over the wire. This
+means that even value query string values (e.g., ":") are url encoded. This
+makes the Query class match PHP's http_build_query function. However, if you
+want to send requests over the wire using valid query string characters that do
+not need to be encoded, then you can provide a string to Url::setQuery() and
+pass true as the second argument to specify that the query string is a raw
+string that should not be parsed or encoded (unless a call to getQuery() is
+subsequently made, forcing the query-string to be converted into a Query
+object).
+
+## 5.0.2 - 2014-10-30
+
+* Added a trailing `\r\n` to multipart/form-data payloads. See
+  https://github.com/guzzle/guzzle/pull/871
+* Added a `GuzzleHttp\Pool::send()` convenience method to match the docs.
+* Status codes are now returned as integers. See
+  https://github.com/guzzle/guzzle/issues/881
+* No longer overwriting an existing `application/x-www-form-urlencoded` header
+  when sending POST requests, allowing for customized headers. See
+  https://github.com/guzzle/guzzle/issues/877
+* Improved path URL serialization.
+
+  * No longer double percent-encoding characters in the path or query string if
+    they are already encoded.
+  * Now properly encoding the supplied path to a URL object, instead of only
+    encoding ' ' and '?'.
+  * Note: This has been changed in 5.0.3 to now encode query string values by
+    default unless the `rawString` argument is provided when setting the query
+    string on a URL: Now allowing many more characters to be present in the
+    query string without being percent encoded. See http://tools.ietf.org/html/rfc3986#appendix-A
+
+## 5.0.1 - 2014-10-16
+
+Bugfix release.
+
+* Fixed an issue where connection errors still returned response object in
+  error and end events event though the response is unusable. This has been
+  corrected so that a response is not returned in the `getResponse` method of
+  these events if the response did not complete. https://github.com/guzzle/guzzle/issues/867
+* Fixed an issue where transfer statistics were not being populated in the
+  RingBridge. https://github.com/guzzle/guzzle/issues/866
+
+## 5.0.0 - 2014-10-12
+
+Adding support for non-blocking responses and some minor API cleanup.
+
+### New Features
+
+* Added support for non-blocking responses based on `guzzlehttp/guzzle-ring`.
+* Added a public API for creating a default HTTP adapter.
+* Updated the redirect plugin to be non-blocking so that redirects are sent
+  concurrently. Other plugins like this can now be updated to be non-blocking.
+* Added a "progress" event so that you can get upload and download progress
+  events.
+* Added `GuzzleHttp\Pool` which implements FutureInterface and transfers
+  requests concurrently using a capped pool size as efficiently as possible.
+* Added `hasListeners()` to EmitterInterface.
+* Removed `GuzzleHttp\ClientInterface::sendAll` and marked
+  `GuzzleHttp\Client::sendAll` as deprecated (it's still there, just not the
+  recommended way).
+
+### Breaking changes
+
+The breaking changes in this release are relatively minor. The biggest thing to
+look out for is that request and response objects no longer implement fluent
+interfaces.
+
+* Removed the fluent interfaces (i.e., `return $this`) from requests,
+  responses, `GuzzleHttp\Collection`, `GuzzleHttp\Url`,
+  `GuzzleHttp\Query`, `GuzzleHttp\Post\PostBody`, and
+  `GuzzleHttp\Cookie\SetCookie`. This blog post provides a good outline of
+  why I did this: http://ocramius.github.io/blog/fluent-interfaces-are-evil/.
+  This also makes the Guzzle message interfaces compatible with the current
+  PSR-7 message proposal.
+* Removed "functions.php", so that Guzzle is truly PSR-4 compliant. Except
+  for the HTTP request functions from function.php, these functions are now
+  implemented in `GuzzleHttp\Utils` using camelCase. `GuzzleHttp\json_decode`
+  moved to `GuzzleHttp\Utils::jsonDecode`. `GuzzleHttp\get_path` moved to
+  `GuzzleHttp\Utils::getPath`. `GuzzleHttp\set_path` moved to
+  `GuzzleHttp\Utils::setPath`. `GuzzleHttp\batch` should now be
+  `GuzzleHttp\Pool::batch`, which returns an `objectStorage`. Using functions.php
+  caused problems for many users: they aren't PSR-4 compliant, require an
+  explicit include, and needed an if-guard to ensure that the functions are not
+  declared multiple times.
+* Rewrote adapter layer.
+    * Removing all classes from `GuzzleHttp\Adapter`, these are now
+      implemented as callables that are stored in `GuzzleHttp\Ring\Client`.
+    * Removed the concept of "parallel adapters". Sending requests serially or
+      concurrently is now handled using a single adapter.
+    * Moved `GuzzleHttp\Adapter\Transaction` to `GuzzleHttp\Transaction`. The
+      Transaction object now exposes the request, response, and client as public
+      properties. The getters and setters have been removed.
+* Removed the "headers" event. This event was only useful for changing the
+  body a response once the headers of the response were known. You can implement
+  a similar behavior in a number of ways. One example might be to use a
+  FnStream that has access to the transaction being sent. For example, when the
+  first byte is written, you could check if the response headers match your
+  expectations, and if so, change the actual stream body that is being
+  written to.
+* Removed the `asArray` parameter from
+  `GuzzleHttp\Message\MessageInterface::getHeader`. If you want to get a header
+  value as an array, then use the newly added `getHeaderAsArray()` method of
+  `MessageInterface`. This change makes the Guzzle interfaces compatible with
+  the PSR-7 interfaces.
+* `GuzzleHttp\Message\MessageFactory` no longer allows subclasses to add
+  custom request options using double-dispatch (this was an implementation
+  detail). Instead, you should now provide an associative array to the
+  constructor which is a mapping of the request option name mapping to a
+  function that applies the option value to a request.
+* Removed the concept of "throwImmediately" from exceptions and error events.
+  This control mechanism was used to stop a transfer of concurrent requests
+  from completing. This can now be handled by throwing the exception or by
+  cancelling a pool of requests or each outstanding future request individually.
+* Updated to "GuzzleHttp\Streams" 3.0.
+    * `GuzzleHttp\Stream\StreamInterface::getContents()` no longer accepts a
+      `maxLen` parameter. This update makes the Guzzle streams project
+      compatible with the current PSR-7 proposal.
+    * `GuzzleHttp\Stream\Stream::__construct`,
+      `GuzzleHttp\Stream\Stream::factory`, and
+      `GuzzleHttp\Stream\Utils::create` no longer accept a size in the second
+      argument. They now accept an associative array of options, including the
+      "size" key and "metadata" key which can be used to provide custom metadata.
+
+## 4.2.2 - 2014-09-08
+
+* Fixed a memory leak in the CurlAdapter when reusing cURL handles.
+* No longer using `request_fulluri` in stream adapter proxies.
+* Relative redirects are now based on the last response, not the first response.
+
+## 4.2.1 - 2014-08-19
+
+* Ensuring that the StreamAdapter does not always add a Content-Type header
+* Adding automated github releases with a phar and zip
+
+## 4.2.0 - 2014-08-17
+
+* Now merging in default options using a case-insensitive comparison.
+  Closes https://github.com/guzzle/guzzle/issues/767
+* Added the ability to automatically decode `Content-Encoding` response bodies
+  using the `decode_content` request option. This is set to `true` by default
+  to decode the response body if it comes over the wire with a
+  `Content-Encoding`. Set this value to `false` to disable decoding the
+  response content, and pass a string to provide a request `Accept-Encoding`
+  header and turn on automatic response decoding. This feature now allows you
+  to pass an `Accept-Encoding` header in the headers of a request but still
+  disable automatic response decoding.
+  Closes https://github.com/guzzle/guzzle/issues/764
+* Added the ability to throw an exception immediately when transferring
+  requests in parallel. Closes https://github.com/guzzle/guzzle/issues/760
+* Updating guzzlehttp/streams dependency to ~2.1
+* No longer utilizing the now deprecated namespaced methods from the stream
+  package.
+
+## 4.1.8 - 2014-08-14
+
+* Fixed an issue in the CurlFactory that caused setting the `stream=false`
+  request option to throw an exception.
+  See: https://github.com/guzzle/guzzle/issues/769
+* TransactionIterator now calls rewind on the inner iterator.
+  See: https://github.com/guzzle/guzzle/pull/765
+* You can now set the `Content-Type` header to `multipart/form-data`
+  when creating POST requests to force multipart bodies.
+  See https://github.com/guzzle/guzzle/issues/768
+
+## 4.1.7 - 2014-08-07
+
+* Fixed an error in the HistoryPlugin that caused the same request and response
+  to be logged multiple times when an HTTP protocol error occurs.
+* Ensuring that cURL does not add a default Content-Type when no Content-Type
+  has been supplied by the user. This prevents the adapter layer from modifying
+  the request that is sent over the wire after any listeners may have already
+  put the request in a desired state (e.g., signed the request).
+* Throwing an exception when you attempt to send requests that have the
+  "stream" set to true in parallel using the MultiAdapter.
+* Only calling curl_multi_select when there are active cURL handles. This was
+  previously changed and caused performance problems on some systems due to PHP
+  always selecting until the maximum select timeout.
+* Fixed a bug where multipart/form-data POST fields were not correctly
+  aggregated (e.g., values with "&").
+
+## 4.1.6 - 2014-08-03
+
+* Added helper methods to make it easier to represent messages as strings,
+  including getting the start line and getting headers as a string.
+
+## 4.1.5 - 2014-08-02
+
+* Automatically retrying cURL "Connection died, retrying a fresh connect"
+  errors when possible.
+* cURL implementation cleanup
+* Allowing multiple event subscriber listeners to be registered per event by
+  passing an array of arrays of listener configuration.
+
+## 4.1.4 - 2014-07-22
+
+* Fixed a bug that caused multi-part POST requests with more than one field to
+  serialize incorrectly.
+* Paths can now be set to "0"
+* `ResponseInterface::xml` now accepts a `libxml_options` option and added a
+  missing default argument that was required when parsing XML response bodies.
+* A `save_to` stream is now created lazily, which means that files are not
+  created on disk unless a request succeeds.
+
+## 4.1.3 - 2014-07-15
+
+* Various fixes to multipart/form-data POST uploads
+* Wrapping function.php in an if-statement to ensure Guzzle can be used
+  globally and in a Composer install
+* Fixed an issue with generating and merging in events to an event array
+* POST headers are only applied before sending a request to allow you to change
+  the query aggregator used before uploading
+* Added much more robust query string parsing
+* Fixed various parsing and normalization issues with URLs
+* Fixing an issue where multi-valued headers were not being utilized correctly
+  in the StreamAdapter
+
+## 4.1.2 - 2014-06-18
+
+* Added support for sending payloads with GET requests
+
+## 4.1.1 - 2014-06-08
+
+* Fixed an issue related to using custom message factory options in subclasses
+* Fixed an issue with nested form fields in a multi-part POST
+* Fixed an issue with using the `json` request option for POST requests
+* Added `ToArrayInterface` to `GuzzleHttp\Cookie\CookieJar`
+
+## 4.1.0 - 2014-05-27
+
+* Added a `json` request option to easily serialize JSON payloads.
+* Added a `GuzzleHttp\json_decode()` wrapper to safely parse JSON.
+* Added `setPort()` and `getPort()` to `GuzzleHttp\Message\RequestInterface`.
+* Added the ability to provide an emitter to a client in the client constructor.
+* Added the ability to persist a cookie session using $_SESSION.
+* Added a trait that can be used to add event listeners to an iterator.
+* Removed request method constants from RequestInterface.
+* Fixed warning when invalid request start-lines are received.
+* Updated MessageFactory to work with custom request option methods.
+* Updated cacert bundle to latest build.
+
+4.0.2 (2014-04-16)
+------------------
+
+* Proxy requests using the StreamAdapter now properly use request_fulluri (#632)
+* Added the ability to set scalars as POST fields (#628)
+
+## 4.0.1 - 2014-04-04
+
+* The HTTP status code of a response is now set as the exception code of
+  RequestException objects.
+* 303 redirects will now correctly switch from POST to GET requests.
+* The default parallel adapter of a client now correctly uses the MultiAdapter.
+* HasDataTrait now initializes the internal data array as an empty array so
+  that the toArray() method always returns an array.
+
+## 4.0.0 - 2014-03-29
+
+* For more information on the 4.0 transition, see:
+  http://mtdowling.com/blog/2014/03/15/guzzle-4-rc/
+* For information on changes and upgrading, see:
+  https://github.com/guzzle/guzzle/blob/master/UPGRADING.md#3x-to-40
+* Added `GuzzleHttp\batch()` as a convenience function for sending requests in
+  parallel without needing to write asynchronous code.
+* Restructured how events are added to `GuzzleHttp\ClientInterface::sendAll()`.
+  You can now pass a callable or an array of associative arrays where each
+  associative array contains the "fn", "priority", and "once" keys.
+
+## 4.0.0.rc-2 - 2014-03-25
+
+* Removed `getConfig()` and `setConfig()` from clients to avoid confusion
+  around whether things like base_url, message_factory, etc. should be able to
+  be retrieved or modified.
+* Added `getDefaultOption()` and `setDefaultOption()` to ClientInterface
+* functions.php functions were renamed using snake_case to match PHP idioms
+* Added support for `HTTP_PROXY`, `HTTPS_PROXY`, and
+  `GUZZLE_CURL_SELECT_TIMEOUT` environment variables
+* Added the ability to specify custom `sendAll()` event priorities
+* Added the ability to specify custom stream context options to the stream
+  adapter.
+* Added a functions.php function for `get_path()` and `set_path()`
+* CurlAdapter and MultiAdapter now use a callable to generate curl resources
+* MockAdapter now properly reads a body and emits a `headers` event
+* Updated Url class to check if a scheme and host are set before adding ":"
+  and "//". This allows empty Url (e.g., "") to be serialized as "".

+* Curl classes now properly throw AdapterExceptions
+* Various performance optimizations
+* Streams are created with the faster `Stream\create()` function
+* Marked deprecation_proxy() as internal

+
+## 3.8.1 - 2014-01-28
+
+* Bug: Always using GET requests when redirecting from a 303 response
+* Bug: CURLOPT_SSL_VERIFYHOST is now correctly set to false when setting `$certificateAuthority` to false in

+* Bug: RedirectPlugin now uses strict RFC 3986 compliance when combining a base URL with a relative URL
+* Bug: The body of a request can now be set to `"0"`
+* Sending PHP stream requests no longer forces `HTTP/1.0`
+* Adding more information to ExceptionCollection exceptions so that users have more context, including a stack trace of
+  each sub-exception
+* Updated the `$ref` attribute in service descriptions to merge over any existing parameters of a schema (rather than
+  clobbering everything).
+* Merging URLs will now use the query string object from the relative URL (thus allowing custom query aggregators)
+* Query strings are now parsed in a way that they do no convert empty keys with no value to have a dangling `=`.
+  For example `foo&bar=baz` is now correctly parsed and recognized as `foo&bar=baz` rather than `foo=&bar=baz`.
+* Now properly escaping the regular expression delimiter when matching Cookie domains.
+* Network access is now disabled when loading XML documents
+

+  (see https://github.com/aws/aws-sdk-php/issues/147)
+* Bug fix: Cleaned up and fixed URL dot segment removal to properly resolve internal dots
+* Minimum PHP version is now properly specified as 5.3.3 (up from 5.3.2) (#420)
+* Updated the bundled cacert.pem (#419)
+* OauthPlugin now supports adding authentication to headers or query string (#425)
+
+## 3.7.3 - 2013-09-08

+  See https://github.com/guzzle/guzzle/issues/371
+* Bug fix: Cookie domains are now matched correctly according to RFC 6265
+  See https://github.com/guzzle/guzzle/issues/377
+* Bug fix: GET parameters are now used when calculating an OAuth signature

+
+## 3.7.0 - 2013-06-10
+
+* See UPGRADING.md for more information on how to upgrade.
+* Requests now support the ability to specify an array of $options when creating a request to more easily modify a
+  request. You can pass a 'request.options' configuration setting to a client to apply default request options to
+  every request created by a client (e.g. default query string variables, headers, curl options, etc.).
+* Added a static facade class that allows you to use Guzzle with static methods and mount the class to `\Guzzle`.
+  See `Guzzle\Http\StaticClient::mount`.
+* Added `command.request_options` to `Guzzle\Service\Command\AbstractCommand` to pass request options to requests
+      created by a command (e.g. custom headers, query string variables, timeout settings, etc.).
+* Stream size in `Guzzle\Stream\PhpStreamRequestFactory` will now be set if Content-Length is returned in the
+  headers of a response
+* Added `Guzzle\Common\Collection::setPath($path, $value)` to set a value into an array using a nested key
+  (e.g. `$collection->setPath('foo/baz/bar', 'test'); echo $collection['foo']['bar']['bar'];`)
+* ServiceBuilders now support storing and retrieving arbitrary data
+* CachePlugin can now purge all resources for a given URI
+* CachePlugin can automatically purge matching cached items when a non-idempotent request is sent to a resource
+* CachePlugin now uses the Vary header to determine if a resource is a cache hit
+* `Guzzle\Http\Message\Response` now implements `\Serializable`
+* Added `Guzzle\Cache\CacheAdapterFactory::fromCache()` to more easily create cache adapters
+* `Guzzle\Service\ClientInterface::execute()` now accepts an array, single command, or Traversable
+* Fixed a bug in `Guzzle\Http\Message\Header\Link::addLink()`
+* Better handling of calculating the size of a stream in `Guzzle\Stream\Stream` using fstat() and caching the size
+* `Guzzle\Common\Exception\ExceptionCollection` now creates a more readable exception message
+* Fixing BC break: Added back the MonologLogAdapter implementation rather than extending from PsrLog so that older
+  Symfony users can still use the old version of Monolog.
+* Fixing BC break: Added the implementation back in for `Guzzle\Http\Message\AbstractMessage::getTokenizedHeader()`.
+  Now triggering an E_USER_DEPRECATED warning when used. Use `$message->getHeader()->parseParams()`.
+* Several performance improvements to `Guzzle\Common\Collection`
+* Added an `$options` argument to the end of the following methods of `Guzzle\Http\ClientInterface`:
+  createRequest, head, delete, put, patch, post, options, prepareRequest
+* Added an `$options` argument to the end of `Guzzle\Http\Message\Request\RequestFactoryInterface::createRequest()`
+* Added an `applyOptions()` method to `Guzzle\Http\Message\Request\RequestFactoryInterface`
+* Changed `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $body = null)` to
+  `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $options = array())`. You can still pass in a
+  resource, string, or EntityBody into the $options parameter to specify the download location of the response.
+* Changed `Guzzle\Common\Collection::__construct($data)` to no longer accepts a null value for `$data` but a
+  default `array()`
+* Added `Guzzle\Stream\StreamInterface::isRepeatable`
+* Removed `Guzzle\Http\ClientInterface::setDefaultHeaders(). Use
+  $client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`. or
+  $client->getConfig()->setPath('request.options/headers', array('header_name' => 'value'))`.
+* Removed `Guzzle\Http\ClientInterface::getDefaultHeaders(). Use $client->getConfig()->getPath('request.options/headers')`.
+* Removed `Guzzle\Http\ClientInterface::expandTemplate()`
+* Removed `Guzzle\Http\ClientInterface::setRequestFactory()`
+* Removed `Guzzle\Http\ClientInterface::getCurlMulti()`
+* Removed `Guzzle\Http\Message\RequestInterface::canCache`
+* Removed `Guzzle\Http\Message\RequestInterface::setIsRedirect`
+* Removed `Guzzle\Http\Message\RequestInterface::isRedirect`
+* Made `Guzzle\Http\Client::expandTemplate` and `getUriTemplate` protected methods.
+* You can now enable E_USER_DEPRECATED warnings to see if you are using a deprecated method by setting
+  `Guzzle\Common\Version::$emitWarnings` to true.
+* Marked `Guzzle\Http\Message\Request::isResponseBodyRepeatable()` as deprecated. Use
+      `$request->getResponseBody()->isRepeatable()` instead.
+* Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use
+  `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
+* Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use
+  `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
+* Marked `Guzzle\Http\Message\Request::setIsRedirect()` as deprecated. Use the HistoryPlugin instead.
+* Marked `Guzzle\Http\Message\Request::isRedirect()` as deprecated. Use the HistoryPlugin instead.
+* Marked `Guzzle\Cache\CacheAdapterFactory::factory()` as deprecated
+* Marked 'command.headers', 'command.response_body' and 'command.on_complete' as deprecated for AbstractCommand.
+  These will work through Guzzle 4.0
+* Marked 'request.params' for `Guzzle\Http\Client` as deprecated. Use [request.options][params].
+* Marked `Guzzle\Service\Client::enableMagicMethods()` as deprecated. Magic methods can no longer be disabled on a Guzzle\Service\Client.
+* Marked `Guzzle\Service\Client::getDefaultHeaders()` as deprecated. Use $client->getConfig()->getPath('request.options/headers')`.
+* Marked `Guzzle\Service\Client::setDefaultHeaders()` as deprecated. Use $client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`.
+* Marked `Guzzle\Parser\Url\UrlParser` as deprecated. Just use PHP's `parse_url()` and percent encode your UTF-8.
+* Marked `Guzzle\Common\Collection::inject()` as deprecated.
+* Marked `Guzzle\Plugin\CurlAuth\CurlAuthPlugin` as deprecated. Use `$client->getConfig()->setPath('request.options/auth', array('user', 'pass', 'Basic|Digest');`
+* CacheKeyProviderInterface and DefaultCacheKeyProvider are no longer used. All of this logic is handled in a
+  CacheStorageInterface. These two objects and interface will be removed in a future version.
+* Always setting X-cache headers on cached responses
+* Default cache TTLs are now handled by the CacheStorageInterface of a CachePlugin
+* `CacheStorageInterface::cache($key, Response $response, $ttl = null)` has changed to `cache(RequestInterface
+  $request, Response $response);`
+* `CacheStorageInterface::fetch($key)` has changed to `fetch(RequestInterface $request);`
+* `CacheStorageInterface::delete($key)` has changed to `delete(RequestInterface $request);`
+* Added `CacheStorageInterface::purge($url)`
+* `DefaultRevalidation::__construct(CacheKeyProviderInterface $cacheKey, CacheStorageInterface $cache, CachePlugin
+  $plugin)` has changed to `DefaultRevalidation::__construct(CacheStorageInterface $cache,
+  CanCacheStrategyInterface $canCache = null)`
+* Added `RevalidationInterface::shouldRevalidate(RequestInterface $request, Response $response)`
+
+## 3.6.0 - 2013-05-29
+
+* ServiceDescription now implements ToArrayInterface
+* Added command.hidden_params to blacklist certain headers from being treated as additionalParameters
+* Guzzle can now correctly parse incomplete URLs
+* Mixed casing of headers are now forced to be a single consistent casing across all values for that header.
+* Messages internally use a HeaderCollection object to delegate handling case-insensitive header resolution
+* Removed the whole changedHeader() function system of messages because all header changes now go through addHeader().
+* Specific header implementations can be created for complex headers. When a message creates a header, it uses a
+  HeaderFactory which can map specific headers to specific header classes. There is now a Link header and
+  CacheControl header implementation.
+* Removed from interface: Guzzle\Http\ClientInterface::setUriTemplate
+* Removed from interface: Guzzle\Http\ClientInterface::setCurlMulti()
+* Removed Guzzle\Http\Message\Request::receivedRequestHeader() and implemented this functionality in
+  Guzzle\Http\Curl\RequestMediator
+* Removed the optional $asString parameter from MessageInterface::getHeader(). Just cast the header to a string.
+* Removed the optional $tryChunkedTransfer option from Guzzle\Http\Message\EntityEnclosingRequestInterface
+* Removed the $asObjects argument from Guzzle\Http\Message\MessageInterface::getHeaders()
+* Removed Guzzle\Parser\ParserRegister::get(). Use getParser()
+* Removed Guzzle\Parser\ParserRegister::set(). Use registerParser().
+* All response header helper functions return a string rather than mixing Header objects and strings inconsistently
+* Removed cURL blacklist support. This is no longer necessary now that Expect, Accept, etc. are managed by Guzzle
+  directly via interfaces
+* Removed the injecting of a request object onto a response object. The methods to get and set a request still exist
+  but are a no-op until removed.
+* Most classes that used to require a `Guzzle\Service\Command\CommandInterface` typehint now request a
+  `Guzzle\Service\Command\ArrayCommandInterface`.
+* Added `Guzzle\Http\Message\RequestInterface::startResponse()` to the RequestInterface to handle injecting a response
+  on a request while the request is still being transferred
+* The ability to case-insensitively search for header values
+* Guzzle\Http\Message\Header::hasExactHeader
+* Guzzle\Http\Message\Header::raw. Use getAll()
+* Deprecated cache control specific methods on Guzzle\Http\Message\AbstractMessage. Use the CacheControl header object
+  instead.
+* `Guzzle\Service\Command\CommandInterface` now extends from ToArrayInterface and ArrayAccess
+* Added the ability to cast Model objects to a string to view debug information.
+
+## 3.5.0 - 2013-05-13
+
+* Bug: Fixed a regression so that request responses are parsed only once per oncomplete event rather than multiple times
+* Bug: Better cleanup of one-time events across the board (when an event is meant to fire once, it will now remove
+  itself from the EventDispatcher)
+* Bug: `Guzzle\Log\MessageFormatter` now properly writes "total_time" and "connect_time" values
+* Bug: Cloning an EntityEnclosingRequest now clones the EntityBody too
+* Bug: Fixed an undefined index error when parsing nested JSON responses with a sentAs parameter that reference a
+  non-existent key
+* Bug: All __call() method arguments are now required (helps with mocking frameworks)
+* Deprecating Response::getRequest() and now using a shallow clone of a request object to remove a circular reference
+  to help with refcount based garbage collection of resources created by sending a request
+* Deprecating ZF1 cache and log adapters. These will be removed in the next major version.
+* Deprecating `Response::getPreviousResponse()` (method signature still exists, but it's deprecated). Use the
+  HistoryPlugin for a history.
+* Added a `responseBody` alias for the `response_body` location
+* Refactored internals to no longer rely on Response::getRequest()
+* HistoryPlugin can now be cast to a string
+* HistoryPlugin now logs transactions rather than requests and responses to more accurately keep track of the requests
+  and responses that are sent over the wire
+* Added `getEffectiveUrl()` and `getRedirectCount()` to Response objects
+
+## 3.4.3 - 2013-04-30

+Guzzle, PHP HTTP client
+=======================
+
+[![Latest Version](https://img.shields.io/github/release/guzzle/guzzle.svg?style=flat-square)](https://github.com/guzzle/guzzle/releases)
+[![Build Status](https://img.shields.io/travis/guzzle/guzzle.svg?style=flat-square)](https://travis-ci.org/guzzle/guzzle)
+[![Total Downloads](https://img.shields.io/packagist/dt/guzzlehttp/guzzle.svg?style=flat-square)](https://packagist.org/packages/guzzlehttp/guzzle)
+
+Guzzle is a PHP HTTP client that makes it easy to send HTTP requests and
+trivial to integrate with web services.
+
+- Simple interface for building query strings, POST requests, streaming large
+  uploads, streaming large downloads, using HTTP cookies, uploading JSON data,
+  etc...
+- Can send both synchronous and asynchronous requests using the same interface.
+- Uses PSR-7 interfaces for requests, responses, and streams. This allows you
+  to utilize other PSR-7 compatible libraries with Guzzle.
+- Abstracts away the underlying HTTP transport, allowing you to write
+  environment and transport agnostic code; i.e., no hard dependency on cURL,
+  PHP streams, sockets, or non-blocking event loops.
+- Middleware system allows you to augment and compose client behavior.
+
+```php
+$client = new \GuzzleHttp\Client();
+$response = $client->request('GET', 'https://api.github.com/repos/guzzle/guzzle');
+
+echo $response->getStatusCode(); # 200
+echo $response->getHeaderLine('content-type'); # 'application/json; charset=utf8'
+echo $response->getBody(); # '{"id": 1420053, "name": "guzzle", ...}'
+
+# Send an asynchronous request.
+$request = new \GuzzleHttp\Psr7\Request('GET', 'http://httpbin.org');
+$promise = $client->sendAsync($request)->then(function ($response) {
+    echo 'I completed! ' . $response->getBody();
+});
+
+$promise->wait();
+```

+- [Stack Overflow](http://stackoverflow.com/questions/tagged/guzzle)
+- [Gitter](https://gitter.im/guzzle/guzzle)
+
+
+## Installing Guzzle
+
+The recommended way to install Guzzle is through
+[Composer](http://getcomposer.org).
+
+```bash
+# Install Composer
+curl -sS https://getcomposer.org/installer | php
+```
+
+Next, run the Composer command to install the latest stable version of Guzzle:
+
+```bash
+composer require guzzlehttp/guzzle
+```
+
+After installing, you need to require Composer's autoloader:
+
+```php
+require 'vendor/autoload.php';
+```
+
+You can then later update Guzzle using composer:
+
+ ```bash
+composer update
+ ```
+

+Guzzle Upgrade Guide
+====================
+
+5.0 to 6.0
+----------
+
+Guzzle now uses [PSR-7](http://www.php-fig.org/psr/psr-7/) for HTTP messages.
+Due to the fact that these messages are immutable, this prompted a refactoring
+of Guzzle to use a middleware based system rather than an event system. Any
+HTTP message interaction (e.g., `GuzzleHttp\Message\Request`) need to be
+updated to work with the new immutable PSR-7 request and response objects. Any
+event listeners or subscribers need to be updated to become middleware
+functions that wrap handlers (or are injected into a
+`GuzzleHttp\HandlerStack`).
+
+- Removed `GuzzleHttp\BatchResults`
+- Removed `GuzzleHttp\Collection`
+- Removed `GuzzleHttp\HasDataTrait`
+- Removed `GuzzleHttp\ToArrayInterface`
+- The `guzzlehttp/streams` dependency has been removed. Stream functionality
+  is now present in the `GuzzleHttp\Psr7` namespace provided by the
+  `guzzlehttp/psr7` package.
+- Guzzle no longer uses ReactPHP promises and now uses the
+  `guzzlehttp/promises` library. We use a custom promise library for three
+  significant reasons:
+  1. React promises (at the time of writing this) are recursive. Promise
+     chaining and promise resolution will eventually blow the stack. Guzzle
+     promises are not recursive as they use a sort of trampolining technique.
+     Note: there has been movement in the React project to modify promises to
+     no longer utilize recursion.
+  2. Guzzle needs to have the ability to synchronously block on a promise to
+     wait for a result. Guzzle promises allows this functionality (and does
+     not require the use of recursion).
+  3. Because we need to be able to wait on a result, doing so using React
+     promises requires wrapping react promises with RingPHP futures. This
+     overhead is no longer needed, reducing stack sizes, reducing complexity,
+     and improving performance.
+- `GuzzleHttp\Mimetypes` has been moved to a function in
+  `GuzzleHttp\Psr7\mimetype_from_extension` and
+  `GuzzleHttp\Psr7\mimetype_from_filename`.
+- `GuzzleHttp\Query` and `GuzzleHttp\QueryParser` have been removed. Query
+  strings must now be passed into request objects as strings, or provided to
+  the `query` request option when creating requests with clients. The `query`
+  option uses PHP's `http_build_query` to convert an array to a string. If you
+  need a different serialization technique, you will need to pass the query
+  string in as a string. There are a couple helper functions that will make
+  working with query strings easier: `GuzzleHttp\Psr7\parse_query` and
+  `GuzzleHttp\Psr7\build_query`.
+- Guzzle no longer has a dependency on RingPHP. Due to the use of a middleware
+  system based on PSR-7, using RingPHP and it's middleware system as well adds
+  more complexity than the benefits it provides. All HTTP handlers that were
+  present in RingPHP have been modified to work directly with PSR-7 messages
+  and placed in the `GuzzleHttp\Handler` namespace. This significantly reduces
+  complexity in Guzzle, removes a dependency, and improves performance. RingPHP
+  will be maintained for Guzzle 5 support, but will no longer be a part of
+  Guzzle 6.
+- As Guzzle now uses a middleware based systems the event system and RingPHP
+  integration has been removed. Note: while the event system has been removed,
+  it is possible to add your own type of event system that is powered by the
+  middleware system.
+  - Removed the `Event` namespace.
+  - Removed the `Subscriber` namespace.
+  - Removed `Transaction` class
+  - Removed `RequestFsm`
+  - Removed `RingBridge`
+  - `GuzzleHttp\Subscriber\Cookie` is now provided by
+    `GuzzleHttp\Middleware::cookies`
+  - `GuzzleHttp\Subscriber\HttpError` is now provided by
+    `GuzzleHttp\Middleware::httpError`
+  - `GuzzleHttp\Subscriber\History` is now provided by
+    `GuzzleHttp\Middleware::history`
+  - `GuzzleHttp\Subscriber\Mock` is now provided by
+    `GuzzleHttp\Handler\MockHandler`
+  - `GuzzleHttp\Subscriber\Prepare` is now provided by
+    `GuzzleHttp\PrepareBodyMiddleware`
+  - `GuzzleHttp\Subscriber\Redirect` is now provided by
+    `GuzzleHttp\RedirectMiddleware`
+- Guzzle now uses `Psr\Http\Message\UriInterface` (implements in
+  `GuzzleHttp\Psr7\Uri`) for URI support. `GuzzleHttp\Url` is now gone.
+- Static functions in `GuzzleHttp\Utils` have been moved to namespaced
+  functions under the `GuzzleHttp` namespace. This requires either a Composer
+  based autoloader or you to include functions.php.
+- `GuzzleHttp\ClientInterface::getDefaultOption` has been renamed to
+  `GuzzleHttp\ClientInterface::getConfig`.
+- `GuzzleHttp\ClientInterface::setDefaultOption` has been removed.
+- The `json` and `xml` methods of response objects has been removed. With the
+  migration to strictly adhering to PSR-7 as the interface for Guzzle messages,
+  adding methods to message interfaces would actually require Guzzle messages
+  to extend from PSR-7 messages rather then work with them directly.
+
+## Migrating to middleware
+
+The change to PSR-7 unfortunately required significant refactoring to Guzzle
+due to the fact that PSR-7 messages are immutable. Guzzle 5 relied on an event
+system from plugins. The event system relied on mutability of HTTP messages and
+side effects in order to work. With immutable messages, you have to change your
+workflow to become more about either returning a value (e.g., functional
+middlewares) or setting a value on an object. Guzzle v6 has chosen the
+functional middleware approach.
+
+Instead of using the event system to listen for things like the `before` event,
+you now create a stack based middleware function that intercepts a request on
+the way in and the promise of the response on the way out. This is a much
+simpler and more predictable approach than the event system and works nicely
+with PSR-7 middleware. Due to the use of promises, the middleware system is
+also asynchronous.
+
+v5:
+
+```php
+use GuzzleHttp\Event\BeforeEvent;
+$client = new GuzzleHttp\Client();
+// Get the emitter and listen to the before event.
+$client->getEmitter()->on('before', function (BeforeEvent $e) {
+    // Guzzle v5 events relied on mutation
+    $e->getRequest()->setHeader('X-Foo', 'Bar');
+});
+```
+
+v6:
+
+In v6, you can modify the request before it is sent using the `mapRequest`
+middleware. The idiomatic way in v6 to modify the request/response lifecycle is
+to setup a handler middleware stack up front and inject the handler into a
+client.
+
+```php
+use GuzzleHttp\Middleware;
+// Create a handler stack that has all of the default middlewares attached
+$handler = GuzzleHttp\HandlerStack::create();
+// Push the handler onto the handler stack
+$handler->push(Middleware::mapRequest(function (RequestInterface $request) {
+    // Notice that we have to return a request object
+    return $request->withHeader('X-Foo', 'Bar');
+}));
+// Inject the handler into the client
+$client = new GuzzleHttp\Client(['handler' => $handler]);
+```
+
+## POST Requests
+
+This version added the [`form_params`](http://guzzle.readthedocs.org/en/latest/request-options.html#form_params)
+and `multipart` request options. `form_params` is an associative array of
+strings or array of strings and is used to serialize an
+`application/x-www-form-urlencoded` POST request. The
+[`multipart`](http://guzzle.readthedocs.org/en/latest/request-options.html#multipart)
+option is now used to send a multipart/form-data POST request.
+
+`GuzzleHttp\Post\PostFile` has been removed. Use the `multipart` option to add
+POST files to a multipart/form-data request.
+
+The `body` option no longer accepts an array to send POST requests. Please use
+`multipart` or `form_params` instead.
+
+The `base_url` option has been renamed to `base_uri`.
+
+4.x to 5.0
+----------
+
+## Rewritten Adapter Layer
+
+Guzzle now uses [RingPHP](http://ringphp.readthedocs.org/en/latest) to send
+HTTP requests. The `adapter` option in a `GuzzleHttp\Client` constructor
+is still supported, but it has now been renamed to `handler`. Instead of
+passing a `GuzzleHttp\Adapter\AdapterInterface`, you must now pass a PHP
+`callable` that follows the RingPHP specification.
+
+## Removed Fluent Interfaces
+
+[Fluent interfaces were removed](http://ocramius.github.io/blog/fluent-interfaces-are-evil)
+from the following classes:
+
+- `GuzzleHttp\Collection`
+- `GuzzleHttp\Url`
+- `GuzzleHttp\Query`
+- `GuzzleHttp\Post\PostBody`
+- `GuzzleHttp\Cookie\SetCookie`
+
+## Removed functions.php
+
+Removed "functions.php", so that Guzzle is truly PSR-4 compliant. The following
+functions can be used as replacements.
+
+- `GuzzleHttp\json_decode` -> `GuzzleHttp\Utils::jsonDecode`
+- `GuzzleHttp\get_path` -> `GuzzleHttp\Utils::getPath`
+- `GuzzleHttp\Utils::setPath` -> `GuzzleHttp\set_path`
+- `GuzzleHttp\Pool::batch` -> `GuzzleHttp\batch`. This function is, however,
+  deprecated in favor of using `GuzzleHttp\Pool::batch()`.
+
+The "procedural" global client has been removed with no replacement (e.g.,
+`GuzzleHttp\get()`, `GuzzleHttp\post()`, etc.). Use a `GuzzleHttp\Client`
+object as a replacement.
+
+## `throwImmediately` has been removed
+
+The concept of "throwImmediately" has been removed from exceptions and error
+events. This control mechanism was used to stop a transfer of concurrent
+requests from completing. This can now be handled by throwing the exception or
+by cancelling a pool of requests or each outstanding future request
+individually.
+
+## headers event has been removed
+
+Removed the "headers" event. This event was only useful for changing the
+body a response once the headers of the response were known. You can implement
+a similar behavior in a number of ways. One example might be to use a
+FnStream that has access to the transaction being sent. For example, when the
+first byte is written, you could check if the response headers match your
+expectations, and if so, change the actual stream body that is being
+written to.
+
+## Updates to HTTP Messages
+
+Removed the `asArray` parameter from
+`GuzzleHttp\Message\MessageInterface::getHeader`. If you want to get a header
+value as an array, then use the newly added `getHeaderAsArray()` method of
+`MessageInterface`. This change makes the Guzzle interfaces compatible with
+the PSR-7 interfaces.
+
+3.x to 4.0
+----------
+
+## Overarching changes:
+
+- Now requires PHP 5.4 or greater.
+- No longer requires cURL to send requests.
+- Guzzle no longer wraps every exception it throws. Only exceptions that are
+  recoverable are now wrapped by Guzzle.
+- Various namespaces have been removed or renamed.
+- No longer requiring the Symfony EventDispatcher. A custom event dispatcher
+  based on the Symfony EventDispatcher is
+  now utilized in `GuzzleHttp\Event\EmitterInterface` (resulting in significant
+  speed and functionality improvements).
+
+Changes per Guzzle 3.x namespace are described below.
+
+## Batch
+
+The `Guzzle\Batch` namespace has been removed. This is best left to
+third-parties to implement on top of Guzzle's core HTTP library.
+
+## Cache
+
+The `Guzzle\Cache` namespace has been removed. (Todo: No suitable replacement
+has been implemented yet, but hoping to utilize a PSR cache interface).
+
+## Common
+
+- Removed all of the wrapped exceptions. It's better to use the standard PHP
+  library for unrecoverable exceptions.
+- `FromConfigInterface` has been removed.
+- `Guzzle\Common\Version` has been removed. The VERSION constant can be found
+  at `GuzzleHttp\ClientInterface::VERSION`.
+
+### Collection
+
+- `getAll` has been removed. Use `toArray` to convert a collection to an array.
+- `inject` has been removed.
+- `keySearch` has been removed.
+- `getPath` no longer supports wildcard expressions. Use something better like
+  JMESPath for this.
+- `setPath` now supports appending to an existing array via the `[]` notation.
+
+### Events
+
+Guzzle no longer requires Symfony's EventDispatcher component. Guzzle now uses
+`GuzzleHttp\Event\Emitter`.
+
+- `Symfony\Component\EventDispatcher\EventDispatcherInterface` is replaced by
+  `GuzzleHttp\Event\EmitterInterface`.
+- `Symfony\Component\EventDispatcher\EventDispatcher` is replaced by
+  `GuzzleHttp\Event\Emitter`.
+- `Symfony\Component\EventDispatcher\Event` is replaced by
+  `GuzzleHttp\Event\Event`, and Guzzle now has an EventInterface in
+  `GuzzleHttp\Event\EventInterface`.
+- `AbstractHasDispatcher` has moved to a trait, `HasEmitterTrait`, and
+  `HasDispatcherInterface` has moved to `HasEmitterInterface`. Retrieving the
+  event emitter of a request, client, etc. now uses the `getEmitter` method
+  rather than the `getDispatcher` method.
+
+#### Emitter
+
+- Use the `once()` method to add a listener that automatically removes itself
+  the first time it is invoked.
+- Use the `listeners()` method to retrieve a list of event listeners rather than
+  the `getListeners()` method.
+- Use `emit()` instead of `dispatch()` to emit an event from an emitter.
+- Use `attach()` instead of `addSubscriber()` and `detach()` instead of
+  `removeSubscriber()`.
+
+```php
+$mock = new Mock();
+// 3.x
+$request->getEventDispatcher()->addSubscriber($mock);
+$request->getEventDispatcher()->removeSubscriber($mock);
+// 4.x
+$request->getEmitter()->attach($mock);
+$request->getEmitter()->detach($mock);
+```
+
+Use the `on()` method to add a listener rather than the `addListener()` method.
+
+```php
+// 3.x
+$request->getEventDispatcher()->addListener('foo', function (Event $event) { /* ... */ } );
+// 4.x
+$request->getEmitter()->on('foo', function (Event $event, $name) { /* ... */ } );
+```
+
+## Http
+
+### General changes
+
+- The cacert.pem certificate has been moved to `src/cacert.pem`.
+- Added the concept of adapters that are used to transfer requests over the
+  wire.
+- Simplified the event system.
+- Sending requests in parallel is still possible, but batching is no longer a
+  concept of the HTTP layer. Instead, you must use the `complete` and `error`
+  events to asynchronously manage parallel request transfers.
+- `Guzzle\Http\Url` has moved to `GuzzleHttp\Url`.
+- `Guzzle\Http\QueryString` has moved to `GuzzleHttp\Query`.
+- QueryAggregators have been rewritten so that they are simply callable
+  functions.
+- `GuzzleHttp\StaticClient` has been removed. Use the functions provided in
+  `functions.php` for an easy to use static client instance.
+- Exceptions in `GuzzleHttp\Exception` have been updated to all extend from
+  `GuzzleHttp\Exception\TransferException`.
+
+### Client
+
+Calling methods like `get()`, `post()`, `head()`, etc. no longer create and
+return a request, but rather creates a request, sends the request, and returns
+the response.
+
+```php
+// 3.0
+$request = $client->get('/');
+$response = $request->send();
+
+// 4.0
+$response = $client->get('/');
+
+// or, to mirror the previous behavior
+$request = $client->createRequest('GET', '/');
+$response = $client->send($request);
+```
+
+`GuzzleHttp\ClientInterface` has changed.
+
+- The `send` method no longer accepts more than one request. Use `sendAll` to
+  send multiple requests in parallel.
+- `setUserAgent()` has been removed. Use a default request option instead. You
+  could, for example, do something like:
+  `$client->setConfig('defaults/headers/User-Agent', 'Foo/Bar ' . $client::getDefaultUserAgent())`.
+- `setSslVerification()` has been removed. Use default request options instead,
+  like `$client->setConfig('defaults/verify', true)`.
+
+`GuzzleHttp\Client` has changed.
+
+- The constructor now accepts only an associative array. You can include a
+  `base_url` string or array to use a URI template as the base URL of a client.
+  You can also specify a `defaults` key that is an associative array of default
+  request options. You can pass an `adapter` to use a custom adapter,
+  `batch_adapter` to use a custom adapter for sending requests in parallel, or
+  a `message_factory` to change the factory used to create HTTP requests and
+  responses.
+- The client no longer emits a `client.create_request` event.
+- Creating requests with a client no longer automatically utilize a URI
+  template. You must pass an array into a creational method (e.g.,
+  `createRequest`, `get`, `put`, etc.) in order to expand a URI template.
+
+### Messages
+
+Messages no longer have references to their counterparts (i.e., a request no
+longer has a reference to it's response, and a response no loger has a
+reference to its request). This association is now managed through a
+`GuzzleHttp\Adapter\TransactionInterface` object. You can get references to
+these transaction objects using request events that are emitted over the
+lifecycle of a request.
+
+#### Requests with a body
+
+- `GuzzleHttp\Message\EntityEnclosingRequest` and
+  `GuzzleHttp\Message\EntityEnclosingRequestInterface` have been removed. The
+  separation between requests that contain a body and requests that do not
+  contain a body has been removed, and now `GuzzleHttp\Message\RequestInterface`
+  handles both use cases.
+- Any method that previously accepts a `GuzzleHttp\Response` object now accept a
+  `GuzzleHttp\Message\ResponseInterface`.
+- `GuzzleHttp\Message\RequestFactoryInterface` has been renamed to
+  `GuzzleHttp\Message\MessageFactoryInterface`. This interface is used to create
+  both requests and responses and is implemented in
+  `GuzzleHttp\Message\MessageFactory`.
+- POST field and file methods have been removed from the request object. You
+  must now use the methods made available to `GuzzleHttp\Post\PostBodyInterface`
+  to control the format of a POST body. Requests that are created using a
+  standard `GuzzleHttp\Message\MessageFactoryInterface` will automatically use
+  a `GuzzleHttp\Post\PostBody` body if the body was passed as an array or if
+  the method is POST and no body is provided.
+
+```php
+$request = $client->createRequest('POST', '/');
+$request->getBody()->setField('foo', 'bar');
+$request->getBody()->addFile(new PostFile('file_key', fopen('/path/to/content', 'r')));
+```
+
+#### Headers
+
+- `GuzzleHttp\Message\Header` has been removed. Header values are now simply
+  represented by an array of values or as a string. Header values are returned
+  as a string by default when retrieving a header value from a message. You can
+  pass an optional argument of `true` to retrieve a header value as an array
+  of strings instead of a single concatenated string.
+- `GuzzleHttp\PostFile` and `GuzzleHttp\PostFileInterface` have been moved to
+  `GuzzleHttp\Post`. This interface has been simplified and now allows the
+  addition of arbitrary headers.
+- Custom headers like `GuzzleHttp\Message\Header\Link` have been removed. Most
+  of the custom headers are now handled separately in specific
+  subscribers/plugins, and `GuzzleHttp\Message\HeaderValues::parseParams()` has
+  been updated to properly handle headers that contain parameters (like the
+  `Link` header).
+
+#### Responses
+
+- `GuzzleHttp\Message\Response::getInfo()` and
+  `GuzzleHttp\Message\Response::setInfo()` have been removed. Use the event
+  system to retrieve this type of information.
+- `GuzzleHttp\Message\Response::getRawHeaders()` has been removed.
+- `GuzzleHttp\Message\Response::getMessage()` has been removed.
+- `GuzzleHttp\Message\Response::calculateAge()` and other cache specific
+  methods have moved to the CacheSubscriber.
+- Header specific helper functions like `getContentMd5()` have been removed.
+  Just use `getHeader('Content-MD5')` instead.
+- `GuzzleHttp\Message\Response::setRequest()` and
+  `GuzzleHttp\Message\Response::getRequest()` have been removed. Use the event
+  system to work with request and response objects as a transaction.
+- `GuzzleHttp\Message\Response::getRedirectCount()` has been removed. Use the
+  Redirect subscriber instead.
+- `GuzzleHttp\Message\Response::isSuccessful()` and other related methods have
+  been removed. Use `getStatusCode()` instead.
+
+#### Streaming responses
+
+Streaming requests can now be created by a client directly, returning a
+`GuzzleHttp\Message\ResponseInterface` object that contains a body stream
+referencing an open PHP HTTP stream.
+
+```php
+// 3.0
+use Guzzle\Stream\PhpStreamRequestFactory;
+$request = $client->get('/');
+$factory = new PhpStreamRequestFactory();
+$stream = $factory->fromRequest($request);
+$data = $stream->read(1024);
+
+// 4.0
+$response = $client->get('/', ['stream' => true]);
+// Read some data off of the stream in the response body
+$data = $response->getBody()->read(1024);
+```
+
+#### Redirects
+
+The `configureRedirects()` method has been removed in favor of a
+`allow_redirects` request option.
+
+```php
+// Standard redirects with a default of a max of 5 redirects
+$request = $client->createRequest('GET', '/', ['allow_redirects' => true]);
+
+// Strict redirects with a custom number of redirects
+$request = $client->createRequest('GET', '/', [
+    'allow_redirects' => ['max' => 5, 'strict' => true]
+]);
+```
+
+#### EntityBody
+
+EntityBody interfaces and classes have been removed or moved to
+`GuzzleHttp\Stream`. All classes and interfaces that once required
+`GuzzleHttp\EntityBodyInterface` now require
+`GuzzleHttp\Stream\StreamInterface`. Creating a new body for a request no
+longer uses `GuzzleHttp\EntityBody::factory` but now uses
+`GuzzleHttp\Stream\Stream::factory` or even better:
+`GuzzleHttp\Stream\create()`.
+
+- `Guzzle\Http\EntityBodyInterface` is now `GuzzleHttp\Stream\StreamInterface`
+- `Guzzle\Http\EntityBody` is now `GuzzleHttp\Stream\Stream`
+- `Guzzle\Http\CachingEntityBody` is now `GuzzleHttp\Stream\CachingStream`
+- `Guzzle\Http\ReadLimitEntityBody` is now `GuzzleHttp\Stream\LimitStream`
+- `Guzzle\Http\IoEmittyinEntityBody` has been removed.
+
+#### Request lifecycle events
+
+Requests previously submitted a large number of requests. The number of events
+emitted over the lifecycle of a request has been significantly reduced to make
+it easier to understand how to extend the behavior of a request. All events
+emitted during the lifecycle of a request now emit a custom
+`GuzzleHttp\Event\EventInterface` object that contains context providing
+methods and a way in which to modify the transaction at that specific point in
+time (e.g., intercept the request and set a response on the transaction).
+
+- `request.before_send` has been renamed to `before` and now emits a
+  `GuzzleHttp\Event\BeforeEvent`
+- `request.complete` has been renamed to `complete` and now emits a
+  `GuzzleHttp\Event\CompleteEvent`.
+- `request.sent` has been removed. Use `complete`.
+- `request.success` has been removed. Use `complete`.
+- `error` is now an event that emits a `GuzzleHttp\Event\ErrorEvent`.
+- `request.exception` has been removed. Use `error`.
+- `request.receive.status_line` has been removed.
+- `curl.callback.progress` has been removed. Use a custom `StreamInterface` to
+  maintain a status update.
+- `curl.callback.write` has been removed. Use a custom `StreamInterface` to
+  intercept writes.
+- `curl.callback.read` has been removed. Use a custom `StreamInterface` to
+  intercept reads.
+
+`headers` is a new event that is emitted after the response headers of a
+request have been received before the body of the response is downloaded. This
+event emits a `GuzzleHttp\Event\HeadersEvent`.
+
+You can intercept a request and inject a response using the `intercept()` event
+of a `GuzzleHttp\Event\BeforeEvent`, `GuzzleHttp\Event\CompleteEvent`, and
+`GuzzleHttp\Event\ErrorEvent` event.
+
+See: http://docs.guzzlephp.org/en/latest/events.html
+
+## Inflection
+
+The `Guzzle\Inflection` namespace has been removed. This is not a core concern
+of Guzzle.
+
+## Iterator
+
+The `Guzzle\Iterator` namespace has been removed.
+
+- `Guzzle\Iterator\AppendIterator`, `Guzzle\Iterator\ChunkedIterator`, and
+  `Guzzle\Iterator\MethodProxyIterator` are nice, but not a core requirement of
+  Guzzle itself.
+- `Guzzle\Iterator\FilterIterator` is no longer needed because an equivalent
+  class is shipped with PHP 5.4.
+- `Guzzle\Iterator\MapIterator` is not really needed when using PHP 5.5 because
+  it's easier to just wrap an iterator in a generator that maps values.
+
+For a replacement of these iterators, see https://github.com/nikic/iter
+
+## Log
+
+The LogPlugin has moved to https://github.com/guzzle/log-subscriber. The
+`Guzzle\Log` namespace has been removed. Guzzle now relies on
+`Psr\Log\LoggerInterface` for all logging. The MessageFormatter class has been
+moved to `GuzzleHttp\Subscriber\Log\Formatter`.
+
+## Parser
+
+The `Guzzle\Parser` namespace has been removed. This was previously used to
+make it possible to plug in custom parsers for cookies, messages, URI
+templates, and URLs; however, this level of complexity is not needed in Guzzle
+so it has been removed.
+
+- Cookie: Cookie parsing logic has been moved to
+  `GuzzleHttp\Cookie\SetCookie::fromString`.
+- Message: Message parsing logic for both requests and responses has been moved
+  to `GuzzleHttp\Message\MessageFactory::fromMessage`. Message parsing is only
+  used in debugging or deserializing messages, so it doesn't make sense for
+  Guzzle as a library to add this level of complexity to parsing messages.
+- UriTemplate: URI template parsing has been moved to
+  `GuzzleHttp\UriTemplate`. The Guzzle library will automatically use the PECL
+  URI template library if it is installed.
+- Url: URL parsing is now performed in `GuzzleHttp\Url::fromString` (previously
+  it was `Guzzle\Http\Url::factory()`). If custom URL parsing is necessary,
+  then developers are free to subclass `GuzzleHttp\Url`.
+
+## Plugin
+
+The `Guzzle\Plugin` namespace has been renamed to `GuzzleHttp\Subscriber`.
+Several plugins are shipping with the core Guzzle library under this namespace.
+
+- `GuzzleHttp\Subscriber\Cookie`: Replaces the old CookiePlugin. Cookie jar
+  code has moved to `GuzzleHttp\Cookie`.
+- `GuzzleHttp\Subscriber\History`: Replaces the old HistoryPlugin.
+- `GuzzleHttp\Subscriber\HttpError`: Throws errors when a bad HTTP response is
+  received.
+- `GuzzleHttp\Subscriber\Mock`: Replaces the old MockPlugin.
+- `GuzzleHttp\Subscriber\Prepare`: Prepares the body of a request just before
+  sending. This subscriber is attached to all requests by default.
+- `GuzzleHttp\Subscriber\Redirect`: Replaces the RedirectPlugin.
+
+The following plugins have been removed (third-parties are free to re-implement
+these if needed):
+
+- `GuzzleHttp\Plugin\Async` has been removed.
+- `GuzzleHttp\Plugin\CurlAuth` has been removed.
+- `GuzzleHttp\Plugin\ErrorResponse\ErrorResponsePlugin` has been removed. This
+  functionality should instead be implemented with event listeners that occur
+  after normal response parsing occurs in the guzzle/command package.
+
+The following plugins are not part of the core Guzzle package, but are provided
+in separate repositories:
+
+- `Guzzle\Http\Plugin\BackoffPlugin` has been rewritten to be much simpler
+  to build custom retry policies using simple functions rather than various
+  chained classes. See: https://github.com/guzzle/retry-subscriber
+- `Guzzle\Http\Plugin\Cache\CachePlugin` has moved to
+  https://github.com/guzzle/cache-subscriber
+- `Guzzle\Http\Plugin\Log\LogPlugin` has moved to
+  https://github.com/guzzle/log-subscriber
+- `Guzzle\Http\Plugin\Md5\Md5Plugin` has moved to
+  https://github.com/guzzle/message-integrity-subscriber
+- `Guzzle\Http\Plugin\Mock\MockPlugin` has moved to
+  `GuzzleHttp\Subscriber\MockSubscriber`.
+- `Guzzle\Http\Plugin\Oauth\OauthPlugin` has moved to
+  https://github.com/guzzle/oauth-subscriber
+
+## Service
+
+The service description layer of Guzzle has moved into two separate packages:
+
+- http://github.com/guzzle/command Provides a high level abstraction over web
+  services by representing web service operations using commands.
+- http://github.com/guzzle/guzzle-services Provides an implementation of
+  guzzle/command that provides request serialization and response parsing using
+  Guzzle service descriptions.
+
+## Stream
+
+Stream have moved to a separate package available at
+https://github.com/guzzle/streams.
+
+`Guzzle\Stream\StreamInterface` has been given a large update to cleanly take
+on the responsibilities of `Guzzle\Http\EntityBody` and
+`Guzzle\Http\EntityBodyInterface` now that they have been removed. The number
+of methods implemented by the `StreamInterface` has been drastically reduced to
+allow developers to more easily extend and decorate stream behavior.
+
+## Removed methods from StreamInterface
+
+- `getStream` and `setStream` have been removed to better encapsulate streams.
+- `getMetadata` and `setMetadata` have been removed in favor of
+  `GuzzleHttp\Stream\MetadataStreamInterface`.
+- `getWrapper`, `getWrapperData`, `getStreamType`, and `getUri` have all been
+  removed. This data is accessible when
+  using streams that implement `GuzzleHttp\Stream\MetadataStreamInterface`.
+- `rewind` has been removed. Use `seek(0)` for a similar behavior.
+
+## Renamed methods
+
+- `detachStream` has been renamed to `detach`.
+- `feof` has been renamed to `eof`.
+- `ftell` has been renamed to `tell`.
+- `readLine` has moved from an instance method to a static class method of
+  `GuzzleHttp\Stream\Stream`.
+
+## Metadata streams
+
+`GuzzleHttp\Stream\MetadataStreamInterface` has been added to denote streams
+that contain additional metadata accessible via `getMetadata()`.
+`GuzzleHttp\Stream\StreamInterface::getMetadata` and
+`GuzzleHttp\Stream\StreamInterface::setMetadata` have been removed.
+
+## StreamRequestFactory
+
+The entire concept of the StreamRequestFactory has been removed. The way this
+was used in Guzzle 3 broke the actual interface of sending streaming requests
+(instead of getting back a Response, you got a StreamInterface). Streaming
+PHP requests are now implemented through the `GuzzleHttp\Adapter\StreamAdapter`.
+
+3.6 to 3.7
+----------
+
+### Deprecations
+
+- You can now enable E_USER_DEPRECATED warnings to see if you are using any deprecated methods.:
+
+```php
+\Guzzle\Common\Version::$emitWarnings = true;
+```
+
+The following APIs and options have been marked as deprecated:
+
+- Marked `Guzzle\Http\Message\Request::isResponseBodyRepeatable()` as deprecated. Use `$request->getResponseBody()->isRepeatable()` instead.
+- Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
+- Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
+- Marked `Guzzle\Http\Message\Request::setIsRedirect()` as deprecated. Use the HistoryPlugin instead.
+- Marked `Guzzle\Http\Message\Request::isRedirect()` as deprecated. Use the HistoryPlugin instead.
+- Marked `Guzzle\Cache\CacheAdapterFactory::factory()` as deprecated
+- Marked `Guzzle\Service\Client::enableMagicMethods()` as deprecated. Magic methods can no longer be disabled on a Guzzle\Service\Client.
+- Marked `Guzzle\Parser\Url\UrlParser` as deprecated. Just use PHP's `parse_url()` and percent encode your UTF-8.
+- Marked `Guzzle\Common\Collection::inject()` as deprecated.
+- Marked `Guzzle\Plugin\CurlAuth\CurlAuthPlugin` as deprecated. Use
+  `$client->getConfig()->setPath('request.options/auth', array('user', 'pass', 'Basic|Digest|NTLM|Any'));` or
+  `$client->setDefaultOption('auth', array('user', 'pass', 'Basic|Digest|NTLM|Any'));`
+
+3.7 introduces `request.options` as a parameter for a client configuration and as an optional argument to all creational
+request methods. When paired with a client's configuration settings, these options allow you to specify default settings
+for various aspects of a request. Because these options make other previous configuration options redundant, several
+configuration options and methods of a client and AbstractCommand have been deprecated.
+
+- Marked `Guzzle\Service\Client::getDefaultHeaders()` as deprecated. Use `$client->getDefaultOption('headers')`.
+- Marked `Guzzle\Service\Client::setDefaultHeaders()` as deprecated. Use `$client->setDefaultOption('headers/{header_name}', 'value')`.
+- Marked 'request.params' for `Guzzle\Http\Client` as deprecated. Use `$client->setDefaultOption('params/{param_name}', 'value')`
+- Marked 'command.headers', 'command.response_body' and 'command.on_complete' as deprecated for AbstractCommand. These will work through Guzzle 4.0
+
+        $command = $client->getCommand('foo', array(
+            'command.headers' => array('Test' => '123'),
+            'command.response_body' => '/path/to/file'
+        ));
+
+        // Should be changed to:
+
+        $command = $client->getCommand('foo', array(
+            'command.request_options' => array(
+                'headers' => array('Test' => '123'),
+                'save_as' => '/path/to/file'
+            )
+        ));
+
+### Interface changes
+
+Additions and changes (you will need to update any implementations or subclasses you may have created):
+
+- Added an `$options` argument to the end of the following methods of `Guzzle\Http\ClientInterface`:
+  createRequest, head, delete, put, patch, post, options, prepareRequest
+- Added an `$options` argument to the end of `Guzzle\Http\Message\Request\RequestFactoryInterface::createRequest()`
+- Added an `applyOptions()` method to `Guzzle\Http\Message\Request\RequestFactoryInterface`
+- Changed `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $body = null)` to
+  `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $options = array())`. You can still pass in a
+  resource, string, or EntityBody into the $options parameter to specify the download location of the response.
+- Changed `Guzzle\Common\Collection::__construct($data)` to no longer accepts a null value for `$data` but a
+  default `array()`
+- Added `Guzzle\Stream\StreamInterface::isRepeatable`
+- Made `Guzzle\Http\Client::expandTemplate` and `getUriTemplate` protected methods.
+
+The following methods were removed from interfaces. All of these methods are still available in the concrete classes
+that implement them, but you should update your code to use alternative methods:
+
+- Removed `Guzzle\Http\ClientInterface::setDefaultHeaders(). Use
+  `$client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`. or
+  `$client->getConfig()->setPath('request.options/headers', array('header_name' => 'value'))` or
+  `$client->setDefaultOption('headers/{header_name}', 'value')`. or
+  `$client->setDefaultOption('headers', array('header_name' => 'value'))`.
+- Removed `Guzzle\Http\ClientInterface::getDefaultHeaders(). Use `$client->getConfig()->getPath('request.options/headers')`.
+- Removed `Guzzle\Http\ClientInterface::expandTemplate()`. This is an implementation detail.
+- Removed `Guzzle\Http\ClientInterface::setRequestFactory()`. This is an implementation detail.
+- Removed `Guzzle\Http\ClientInterface::getCurlMulti()`. This is a very specific implementation detail.
+- Removed `Guzzle\Http\Message\RequestInterface::canCache`. Use the CachePlugin.
+- Removed `Guzzle\Http\Message\RequestInterface::setIsRedirect`. Use the HistoryPlugin.
+- Removed `Guzzle\Http\Message\RequestInterface::isRedirect`. Use the HistoryPlugin.
+
+### Cache plugin breaking changes
+
+- CacheKeyProviderInterface and DefaultCacheKeyProvider are no longer used. All of this logic is handled in a
+  CacheStorageInterface. These two objects and interface will be removed in a future version.
+- Always setting X-cache headers on cached responses
+- Default cache TTLs are now handled by the CacheStorageInterface of a CachePlugin
+- `CacheStorageInterface::cache($key, Response $response, $ttl = null)` has changed to `cache(RequestInterface
+  $request, Response $response);`
+- `CacheStorageInterface::fetch($key)` has changed to `fetch(RequestInterface $request);`
+- `CacheStorageInterface::delete($key)` has changed to `delete(RequestInterface $request);`
+- Added `CacheStorageInterface::purge($url)`
+- `DefaultRevalidation::__construct(CacheKeyProviderInterface $cacheKey, CacheStorageInterface $cache, CachePlugin
+  $plugin)` has changed to `DefaultRevalidation::__construct(CacheStorageInterface $cache,
+  CanCacheStrategyInterface $canCache = null)`
+- Added `RevalidationInterface::shouldRevalidate(RequestInterface $request, Response $response)`
+
+3.5 to 3.6
+----------
+
+* Mixed casing of headers are now forced to be a single consistent casing across all values for that header.
+* Messages internally use a HeaderCollection object to delegate handling case-insensitive header resolution
+* Removed the whole changedHeader() function system of messages because all header changes now go through addHeader().
+  For example, setHeader() first removes the header using unset on a HeaderCollection and then calls addHeader().
+  Keeping the Host header and URL host in sync is now handled by overriding the addHeader method in Request.
+* Specific header implementations can be created for complex headers. When a message creates a header, it uses a
+  HeaderFactory which can map specific headers to specific header classes. There is now a Link header and
+  CacheControl header implementation.
+* Moved getLinks() from Response to just be used on a Link header object.
+
+If you previously relied on Guzzle\Http\Message\Header::raw(), then you will need to update your code to use the
+HeaderInterface (e.g. toArray(), getAll(), etc.).
+
+### Interface changes
+
+* Removed from interface: Guzzle\Http\ClientInterface::setUriTemplate
+* Removed from interface: Guzzle\Http\ClientInterface::setCurlMulti()
+* Removed Guzzle\Http\Message\Request::receivedRequestHeader() and implemented this functionality in
+  Guzzle\Http\Curl\RequestMediator
+* Removed the optional $asString parameter from MessageInterface::getHeader(). Just cast the header to a string.
+* Removed the optional $tryChunkedTransfer option from Guzzle\Http\Message\EntityEnclosingRequestInterface
+* Removed the $asObjects argument from Guzzle\Http\Message\MessageInterface::getHeaders()
+
+### Removed deprecated functions
+
+* Removed Guzzle\Parser\ParserRegister::get(). Use getParser()
+* Removed Guzzle\Parser\ParserRegister::set(). Use registerParser().
+
+### Deprecations
+
+* The ability to case-insensitively search for header values
+* Guzzle\Http\Message\Header::hasExactHeader
+* Guzzle\Http\Message\Header::raw. Use getAll()
+* Deprecated cache control specific methods on Guzzle\Http\Message\AbstractMessage. Use the CacheControl header object
+  instead.
+
+### Other changes
+
+* All response header helper functions return a string rather than mixing Header objects and strings inconsistently
+* Removed cURL blacklist support. This is no longer necessary now that Expect, Accept, etc. are managed by Guzzle
+  directly via interfaces
+* Removed the injecting of a request object onto a response object. The methods to get and set a request still exist
+  but are a no-op until removed.
+* Most classes that used to require a `Guzzle\Service\Command\CommandInterface` typehint now request a
+  `Guzzle\Service\Command\ArrayCommandInterface`.
+* Added `Guzzle\Http\Message\RequestInterface::startResponse()` to the RequestInterface to handle injecting a response
+  on a request while the request is still being transferred
+* `Guzzle\Service\Command\CommandInterface` now extends from ToArrayInterface and ArrayAccess
+
+3.3 to 3.4
+----------
+
+Base URLs of a client now follow the rules of http://tools.ietf.org/html/rfc3986#section-5.2.2 when merging URLs.
+
+3.2 to 3.3
+----------
+
+### Response::getEtag() quote stripping removed
+
+`Guzzle\Http\Message\Response::getEtag()` no longer strips quotes around the ETag response header
+
+### Removed `Guzzle\Http\Utils`
+
+The `Guzzle\Http\Utils` class was removed. This class was only used for testing.
+
+### Stream wrapper and type
+
+`Guzzle\Stream\Stream::getWrapper()` and `Guzzle\Stream\Stream::getStreamType()` are no longer converted to lowercase.
+
+### curl.emit_io became emit_io
+
+Emitting IO events from a RequestMediator is now a parameter that must be set in a request's curl options using the
+'emit_io' key. This was previously set under a request's parameters using 'curl.emit_io'
+
+3.1 to 3.2
+----------
+
+### CurlMulti is no longer reused globally
+
+Before 3.2, the same CurlMulti object was reused globally for each client. This can cause issue where plugins added
+to a single client can pollute requests dispatched from other clients.
+
+If you still wish to reuse the same CurlMulti object with each client, then you can add a listener to the
+ServiceBuilder's `service_builder.create_client` event to inject a custom CurlMulti object into each client as it is
+created.
+
+```php
+$multi = new Guzzle\Http\Curl\CurlMulti();
+$builder = Guzzle\Service\Builder\ServiceBuilder::factory('/path/to/config.json');
+$builder->addListener('service_builder.create_client', function ($event) use ($multi) {
+    $event['client']->setCurlMulti($multi);
+}
+});
+```
+
+### No default path
+
+URLs no longer have a default path value of '/' if no path was specified.
+
+Before:
+
+```php
+$request = $client->get('http://www.foo.com');
+echo $request->getUrl();
+// >> http://www.foo.com/
+```
+
+After:
+
+```php
+$request = $client->get('http://www.foo.com');
+echo $request->getUrl();
+// >> http://www.foo.com
+```
+
+### Less verbose BadResponseException
+
+The exception message for `Guzzle\Http\Exception\BadResponseException` no longer contains the full HTTP request and
+response information. You can, however, get access to the request and response object by calling `getRequest()` or
+`getResponse()` on the exception object.
+
+### Query parameter aggregation
+
+Multi-valued query parameters are no longer aggregated using a callback function. `Guzzle\Http\Query` now has a
+setAggregator() method that accepts a `Guzzle\Http\QueryAggregator\QueryAggregatorInterface` object. This object is
+responsible for handling the aggregation of multi-valued query string variables into a flattened hash.
+
+2.8 to 3.x
+----------
+
+### Guzzle\Service\Inspector
+
+Change `\Guzzle\Service\Inspector::fromConfig` to `\Guzzle\Common\Collection::fromConfig`
+
+**Before**
+
+```php
+use Guzzle\Service\Inspector;
+
+class YourClient extends \Guzzle\Service\Client
+{
+    public static function factory($config = array())
+    {
+        $default = array();
+        $required = array('base_url', 'username', 'api_key');
+        $config = Inspector::fromConfig($config, $default, $required);
+
+        $client = new self(
+            $config->get('base_url'),
+            $config->get('username'),
+            $config->get('api_key')
+        );
+        $client->setConfig($config);
+
+        $client->setDescription(ServiceDescription::factory(__DIR__ . DIRECTORY_SEPARATOR . 'client.json'));
+
+        return $client;
+    }
+```
+
+**After**
+
+```php
+use Guzzle\Common\Collection;
+
+class YourClient extends \Guzzle\Service\Client
+{
+    public static function factory($config = array())
+    {
+        $default = array();
+        $required = array('base_url', 'username', 'api_key');
+        $config = Collection::fromConfig($config, $default, $required);
+
+        $client = new self(
+            $config->get('base_url'),
+            $config->get('username'),
+            $config->get('api_key')
+        );
+        $client->setConfig($config);
+
+        $client->setDescription(ServiceDescription::factory(__DIR__ . DIRECTORY_SEPARATOR . 'client.json'));
+
+        return $client;
+    }
+```
+
+### Convert XML Service Descriptions to JSON
+
+**Before**
+
+```xml

+
+### Guzzle\Service\Description\ServiceDescription
+
+Commands are now called Operations
+
+**Before**
+
+```php
+use Guzzle\Service\Description\ServiceDescription;
+
+$sd = new ServiceDescription();
+$sd->getCommands();     // @returns ApiCommandInterface[]
+$sd->hasCommand($name);
+$sd->getCommand($name); // @returns ApiCommandInterface|null
+$sd->addCommand($command); // @param ApiCommandInterface $command
+```
+
+**After**
+
+```php

+
+$sd = new ServiceDescription();
+$sd->getOperations();           // @returns OperationInterface[]
+$sd->hasOperation($name);
+$sd->getOperation($name);       // @returns OperationInterface|null
+$sd->addOperation($operation);  // @param OperationInterface $operation
+```
+
+### Guzzle\Common\Inflection\Inflector
+
+Namespace is now `Guzzle\Inflection\Inflector`
+
+### Guzzle\Http\Plugin
+
+Namespace is now `Guzzle\Plugin`. Many other changes occur within this namespace and are detailed in their own sections below.
+
+### Guzzle\Http\Plugin\LogPlugin and Guzzle\Common\Log
+
+Now `Guzzle\Plugin\Log\LogPlugin` and `Guzzle\Log` respectively.
+
+**Before**
+
+```php
+use Guzzle\Common\Log\ClosureLogAdapter;
+use Guzzle\Http\Plugin\LogPlugin;
+
+/** @var \Guzzle\Http\Client */
+$client;
+
+// $verbosity is an integer indicating desired message verbosity level
+$client->addSubscriber(new LogPlugin(new ClosureLogAdapter(function($m) { echo $m; }, $verbosity = LogPlugin::LOG_VERBOSE);
+```
+
+**After**
+
+```php
+use Guzzle\Log\ClosureLogAdapter;
+use Guzzle\Log\MessageFormatter;
+use Guzzle\Plugin\Log\LogPlugin;
+
+/** @var \Guzzle\Http\Client */
+$client;
+
+// $format is a string indicating desired message format -- @see MessageFormatter
+$client->addSubscriber(new LogPlugin(new ClosureLogAdapter(function($m) { echo $m; }, $format = MessageFormatter::DEBUG_FORMAT);
+```
+
+### Guzzle\Http\Plugin\CurlAuthPlugin
+
+Now `Guzzle\Plugin\CurlAuth\CurlAuthPlugin`.
+
+### Guzzle\Http\Plugin\ExponentialBackoffPlugin
+
+Now `Guzzle\Plugin\Backoff\BackoffPlugin`, and other changes.
+
+**Before**
+
+```php
+use Guzzle\Http\Plugin\ExponentialBackoffPlugin;
+
+$backoffPlugin = new ExponentialBackoffPlugin($maxRetries, array_merge(
+        ExponentialBackoffPlugin::getDefaultFailureCodes(), array(429)
+    ));
+
+$client->addSubscriber($backoffPlugin);
+```
+
+**After**
+
+```php
+use Guzzle\Plugin\Backoff\BackoffPlugin;
+use Guzzle\Plugin\Backoff\HttpBackoffStrategy;
+
+// Use convenient factory method instead -- see implementation for ideas of what
+// you can do with chaining backoff strategies
+$backoffPlugin = BackoffPlugin::getExponentialBackoff($maxRetries, array_merge(
+        HttpBackoffStrategy::getDefaultFailureCodes(), array(429)
+    ));
+$client->addSubscriber($backoffPlugin);
+```
+
+### Known Issues
+
+#### [BUG] Accept-Encoding header behavior changed unintentionally.
+
+(See #217) (Fixed in 09daeb8c666fb44499a0646d655a8ae36456575e)
+
+In version 2.8 setting the `Accept-Encoding` header would set the CURLOPT_ENCODING option, which permitted cURL to
+properly handle gzip/deflate compressed responses from the server. In versions affected by this bug this does not happen.
+See issue #217 for a workaround, or use a version containing the fix.

+# Features
+
+- [Promises/A+](https://promisesaplus.com/) implementation.
+- Promise resolution and chaining is handled iteratively, allowing for
+  "infinite" promise chaining.
+- Promises have a synchronous `wait` method.
+- Promises can be cancelled.
+- Works with any object that has a `then` function.
+- C# style async/await coroutine promises using
+  `GuzzleHttp\Promise\coroutine()`.
+
+
+# Quick start
+
+A *promise* represents the eventual result of an asynchronous operation. The
+primary way of interacting with a promise is through its `then` method, which
+registers callbacks to receive either a promise's eventual value or the reason
+why the promise cannot be fulfilled.
+
+
+## Callbacks
+
+Callbacks are registered with the `then` method by providing an optional 
+`$onFulfilled` followed by an optional `$onRejected` function.
+
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise->then(
+    // $onFulfilled
+    function ($value) {
+        echo 'The promise was fulfilled.';
+    },
+    // $onRejected
+    function ($reason) {
+        echo 'The promise was rejected.';
+    }
+);
+```
+
+*Resolving* a promise means that you either fulfill a promise with a *value* or
+reject a promise with a *reason*. Resolving a promises triggers callbacks
+registered with the promises's `then` method. These callbacks are triggered
+only once and in the order in which they were added.
+
+
+## Resolving a promise
+
+Promises are fulfilled using the `resolve($value)` method. Resolving a promise
+with any value other than a `GuzzleHttp\Promise\RejectedPromise` will trigger
+all of the onFulfilled callbacks (resolving a promise with a rejected promise
+will reject the promise and trigger the `$onRejected` callbacks).
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise
+    ->then(function ($value) {
+        // Return a value and don't break the chain
+        return "Hello, " . $value;
+    })
+    // This then is executed after the first then and receives the value
+    // returned from the first then.
+    ->then(function ($value) {
+        echo $value;
+    });
+
+// Resolving the promise triggers the $onFulfilled callbacks and outputs
+// "Hello, reader".
+$promise->resolve('reader.');
+```
+
+
+## Promise forwarding
+
+Promises can be chained one after the other. Each then in the chain is a new
+promise. The return value of a promise is what's forwarded to the next
+promise in the chain. Returning a promise in a `then` callback will cause the
+subsequent promises in the chain to only be fulfilled when the returned promise
+has been fulfilled. The next promise in the chain will be invoked with the
+resolved value of the promise.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$nextPromise = new Promise();
+
+$promise
+    ->then(function ($value) use ($nextPromise) {
+        echo $value;
+        return $nextPromise;
+    })
+    ->then(function ($value) {
+        echo $value;
+    });
+
+// Triggers the first callback and outputs "A"
+$promise->resolve('A');
+// Triggers the second callback and outputs "B"
+$nextPromise->resolve('B');
+```
+
+## Promise rejection
+
+When a promise is rejected, the `$onRejected` callbacks are invoked with the
+rejection reason.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise->then(null, function ($reason) {
+    echo $reason;
+});
+
+$promise->reject('Error!');
+// Outputs "Error!"
+```
+
+## Rejection forwarding
+
+If an exception is thrown in an `$onRejected` callback, subsequent
+`$onRejected` callbacks are invoked with the thrown exception as the reason.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise->then(null, function ($reason) {
+    throw new \Exception($reason);
+})->then(null, function ($reason) {
+    assert($reason->getMessage() === 'Error!');
+});
+
+$promise->reject('Error!');
+```
+
+You can also forward a rejection down the promise chain by returning a
+`GuzzleHttp\Promise\RejectedPromise` in either an `$onFulfilled` or
+`$onRejected` callback.
+
+```php
+use GuzzleHttp\Promise\Promise;
+use GuzzleHttp\Promise\RejectedPromise;
+
+$promise = new Promise();
+$promise->then(null, function ($reason) {
+    return new RejectedPromise($reason);
+})->then(null, function ($reason) {
+    assert($reason === 'Error!');
+});
+
+$promise->reject('Error!');
+```
+
+If an exception is not thrown in a `$onRejected` callback and the callback
+does not return a rejected promise, downstream `$onFulfilled` callbacks are
+invoked using the value returned from the `$onRejected` callback.
+
+```php
+use GuzzleHttp\Promise\Promise;
+use GuzzleHttp\Promise\RejectedPromise;
+
+$promise = new Promise();
+$promise
+    ->then(null, function ($reason) {
+        return "It's ok";
+    })
+    ->then(function ($value) {
+        assert($value === "It's ok");
+    });
+
+$promise->reject('Error!');
+```
+
+# Synchronous wait
+
+You can synchronously force promises to complete using a promise's `wait`
+method. When creating a promise, you can provide a wait function that is used
+to synchronously force a promise to complete. When a wait function is invoked
+it is expected to deliver a value to the promise or reject the promise. If the
+wait function does not deliver a value, then an exception is thrown. The wait
+function provided to a promise constructor is invoked when the `wait` function
+of the promise is called.
+
+```php
+$promise = new Promise(function () use (&$promise) {
+    $promise->resolve('foo');
+});
+
+// Calling wait will return the value of the promise.
+echo $promise->wait(); // outputs "foo"
+```
+
+If an exception is encountered while invoking the wait function of a promise,
+the promise is rejected with the exception and the exception is thrown.
+
+```php
+$promise = new Promise(function () use (&$promise) {
+    throw new \Exception('foo');
+});
+
+$promise->wait(); // throws the exception.
+```
+
+Calling `wait` on a promise that has been fulfilled will not trigger the wait
+function. It will simply return the previously resolved value.
+
+```php
+$promise = new Promise(function () { die('this is not called!'); });
+$promise->resolve('foo');
+echo $promise->wait(); // outputs "foo"
+```
+
+Calling `wait` on a promise that has been rejected will throw an exception. If
+the rejection reason is an instance of `\Exception` the reason is thrown.
+Otherwise, a `GuzzleHttp\Promise\RejectionException` is thrown and the reason
+can be obtained by calling the `getReason` method of the exception.
+
+```php
+$promise = new Promise();
+$promise->reject('foo');
+$promise->wait();

+
+## Unwrapping a promise
+
+When synchronously waiting on a promise, you are joining the state of the
+promise into the current state of execution (i.e., return the value of the
+promise if it was fulfilled or throw an exception if it was rejected). This is
+called "unwrapping" the promise. Waiting on a promise will by default unwrap
+the promise state.
+
+You can force a promise to resolve and *not* unwrap the state of the promise
+by passing `false` to the first argument of the `wait` function:
+
+```php
+$promise = new Promise();
+$promise->reject('foo');
+// This will not throw an exception. It simply ensures the promise has
+// been resolved.
+$promise->wait(false);
+```
+
+When unwrapping a promise, the resolved value of the promise will be waited
+upon until the unwrapped value is not a promise. This means that if you resolve
+promise A with a promise B and unwrap promise A, the value returned by the
+wait function will be the value delivered to promise B.
+
+**Note**: when you do not unwrap the promise, no value is returned.
+
+
+# Cancellation
+
+You can cancel a promise that has not yet been fulfilled using the `cancel()`
+method of a promise. When creating a promise you can provide an optional
+cancel function that when invoked cancels the action of computing a resolution
+of the promise.
+
+
+# API
+
+
+## Promise
+
+When creating a promise object, you can provide an optional `$waitFn` and
+`$cancelFn`. `$waitFn` is a function that is invoked with no arguments and is
+expected to resolve the promise. `$cancelFn` is a function with no arguments
+that is expected to cancel the computation of a promise. It is invoked when the
+`cancel()` method of a promise is called.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise(
+    function () use (&$promise) {
+        $promise->resolve('waited');
+    },
+    function () {
+        // do something that will cancel the promise computation (e.g., close
+        // a socket, cancel a database query, etc...)
+    }
+);
+
+assert('waited' === $promise->wait());
+```
+
+A promise has the following methods:
+
+- `then(callable $onFulfilled, callable $onRejected) : PromiseInterface`
+  
+  Appends fulfillment and rejection handlers to the promise, and returns a new promise resolving to the return value of the called handler.
+
+- `otherwise(callable $onRejected) : PromiseInterface`
+  
+  Appends a rejection handler callback to the promise, and returns a new promise resolving to the return value of the callback if it is called, or to its original fulfillment value if the promise is instead fulfilled.
+
+- `wait($unwrap = true) : mixed`
+
+  Synchronously waits on the promise to complete.
+  
+  `$unwrap` controls whether or not the value of the promise is returned for a
+  fulfilled promise or if an exception is thrown if the promise is rejected.
+  This is set to `true` by default.
+
+- `cancel()`
+
+  Attempts to cancel the promise if possible. The promise being cancelled and
+  the parent most ancestor that has not yet been resolved will also be
+  cancelled. Any promises waiting on the cancelled promise to resolve will also
+  be cancelled.
+
+- `getState() : string`
+
+  Returns the state of the promise. One of `pending`, `fulfilled`, or
+  `rejected`.
+
+- `resolve($value)`
+
+  Fulfills the promise with the given `$value`.
+
+- `reject($reason)`
+
+  Rejects the promise with the given `$reason`.
+
+
+## FulfilledPromise
+
+A fulfilled promise can be created to represent a promise that has been
+fulfilled.
+
+```php
+use GuzzleHttp\Promise\FulfilledPromise;
+
+$promise = new FulfilledPromise('value');
+
+// Fulfilled callbacks are immediately invoked.
+$promise->then(function ($value) {
+    echo $value;
+});
+```
+
+
+## RejectedPromise
+
+A rejected promise can be created to represent a promise that has been
+rejected.
+
+```php
+use GuzzleHttp\Promise\RejectedPromise;
+
+$promise = new RejectedPromise('Error');
+
+// Rejected callbacks are immediately invoked.
+$promise->then(null, function ($reason) {
+    echo $reason;
+});
+```
+
+
+# Promise interop
+
+This library works with foreign promises that have a `then` method. This means
+you can use Guzzle promises with [React promises](https://github.com/reactphp/promise)
+for example. When a foreign promise is returned inside of a then method
+callback, promise resolution will occur recursively.
+
+```php
+// Create a React promise
+$deferred = new React\Promise\Deferred();
+$reactPromise = $deferred->promise();
+
+// Create a Guzzle promise that is fulfilled with a React promise.
+$guzzlePromise = new \GuzzleHttp\Promise\Promise();
+$guzzlePromise->then(function ($value) use ($reactPromise) {
+    // Do something something with the value...
+    // Return the React promise
+    return $reactPromise;
+});
+```
+
+Please note that wait and cancel chaining is no longer possible when forwarding
+a foreign promise. You will need to wrap a third-party promise with a Guzzle
+promise in order to utilize wait and cancel functions with foreign promises.
+
+
+## Event Loop Integration
+
+In order to keep the stack size constant, Guzzle promises are resolved
+asynchronously using a task queue. When waiting on promises synchronously, the
+task queue will be automatically run to ensure that the blocking promise and
+any forwarded promises are resolved. When using promises asynchronously in an
+event loop, you will need to run the task queue on each tick of the loop. If
+you do not run the task queue, then promises will not be resolved.
+
+You can run the task queue using the `run()` method of the global task queue
+instance.
+
+```php
+// Get the global task queue
+$queue = \GuzzleHttp\Promise\queue();
+$queue->run();
+```
+
+For example, you could use Guzzle promises with React using a periodic timer:
+
+```php
+$loop = React\EventLoop\Factory::create();
+$loop->addPeriodicTimer(0, [$queue, 'run']);
+```
+
+*TODO*: Perhaps adding a `futureTick()` on each tick would be faster?
+
+
+# Implementation notes
+
+
+## Promise resolution and chaining is handled iteratively
+
+By shuffling pending handlers from one owner to another, promises are
+resolved iteratively, allowing for "infinite" then chaining.
+
+```php
+<?php
+require 'vendor/autoload.php';
+
+use GuzzleHttp\Promise\Promise;
+
+$parent = new Promise();
+$p = $parent;
+
+for ($i = 0; $i < 1000; $i++) {
+    $p = $p->then(function ($v) {
+        // The stack size remains constant (a good thing)
+        echo xdebug_get_stack_depth() . ', ';
+        return $v + 1;
+    });
+}
+
+$parent->resolve(0);
+var_dump($p->wait()); // int(1000)
+
+```
+
+When a promise is fulfilled or rejected with a non-promise value, the promise
+then takes ownership of the handlers of each child promise and delivers values
+down the chain without using recursion.
+
+When a promise is resolved with another promise, the original promise transfers
+all of its pending handlers to the new promise. When the new promise is
+eventually resolved, all of the pending handlers are delivered the forwarded
+value.
+
+
+## A promise is the deferred.
+
+Some promise libraries implement promises using a deferred object to represent
+a computation and a promise object to represent the delivery of the result of
+the computation. This is a nice separation of computation and delivery because
+consumers of the promise cannot modify the value that will be eventually
+delivered.
+
+One side effect of being able to implement promise resolution and chaining
+iteratively is that you need to be able for one promise to reach into the state
+of another promise to shuffle around ownership of handlers. In order to achieve
+this without making the handlers of a promise publicly mutable, a promise is
+also the deferred value, allowing promises of the same parent class to reach
+into and modify the private properties of promises of the same type. While this
+does allow consumers of the value to modify the resolution or rejection of the
+deferred, it is a small price to pay for keeping the stack size constant.
+
+```php
+$promise = new Promise();
+$promise->then(function ($value) { echo $value; });
+// The promise is the deferred value, so you can deliver a value to it.
+$promise->resolve('foo');
+// prints "foo"
+```

+# Change Log
+
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
+and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html).
+
+
+## [Unreleased]
+
+
+## [1.6.0]
+
+### Added
+
+- Allowed version `^3.0` of `ralouphie/getallheaders` dependency (#244)
+- Added MIME type for WEBP image format (#246)
+- Added more validation of values according to PSR-7 and RFC standards, e.g. status code range (#250, #272)
+
+### Changed
+
+- Tests don't pass with HHVM 4.0, so HHVM support got dropped. Other libraries like composer have done the same. (#262)
+- Accept port number 0 to be valid (#270)
+
+### Fixed
+
+- Fixed subsequent reads from `php://input` in ServerRequest (#247)
+- Fixed readable/writable detection for certain stream modes (#248)
+- Fixed encoding of special characters in the `userInfo` component of an URI (#253)
+
+
+## [1.5.2] - 2018-12-04
+
+### Fixed
+
+- Check body size when getting the message summary
+
+
+## [1.5.1] - 2018-12-04
+
+### Fixed
+
+- Get the summary of a body only if it is readable
+
+
+## [1.5.0] - 2018-12-03
+
+### Added
+
+- Response first-line to response string exception (fixes #145)
+- A test for #129 behavior
+- `get_message_body_summary` function in order to get the message summary
+- `3gp` and `mkv` mime types
+
+### Changed
+
+- Clarify exception message when stream is detached
+
+### Deprecated
+
+- Deprecated parsing folded header lines as per RFC 7230
+
+### Fixed
+
+- Fix `AppendStream::detach` to not close streams
+- `InflateStream` preserves `isSeekable` attribute of the underlying stream
+- `ServerRequest::getUriFromGlobals` to support URLs in query parameters
+
+
+Several other fixes and improvements.
+
+
+## [1.4.2] - 2017-03-20
+
+### Fixed
+
+- Reverted BC break to `Uri::resolve` and `Uri::removeDotSegments` by removing
+  calls to `trigger_error` when deprecated methods are invoked.
+
+
+## [1.4.1] - 2017-02-27
+
+### Added
+
+- Rriggering of silenced deprecation warnings.
+
+### Fixed
+
+- Reverted BC break by reintroducing behavior to automagically fix a URI with a
+  relative path and an authority by adding a leading slash to the path. It's only
+  deprecated now.
+
+
+## [1.4.0] - 2017-02-21
+
+### Added
+
+- Added common URI utility methods based on RFC 3986 (see documentation in the readme):
+  - `Uri::isDefaultPort`
+  - `Uri::isAbsolute`
+  - `Uri::isNetworkPathReference`
+  - `Uri::isAbsolutePathReference`
+  - `Uri::isRelativePathReference`
+  - `Uri::isSameDocumentReference`
+  - `Uri::composeComponents`
+  - `UriNormalizer::normalize`
+  - `UriNormalizer::isEquivalent`
+  - `UriResolver::relativize`
+
+### Changed
+
+- Ensure `ServerRequest::getUriFromGlobals` returns a URI in absolute form.
+- Allow `parse_response` to parse a response without delimiting space and reason.
+- Ensure each URI modification results in a valid URI according to PSR-7 discussions.
+  Invalid modifications will throw an exception instead of returning a wrong URI or
+  doing some magic.
+  - `(new Uri)->withPath('foo')->withHost('example.com')` will throw an exception
+    because the path of a URI with an authority must start with a slash "/" or be empty
+  - `(new Uri())->withScheme('http')` will return `'http://localhost'`
+
+### Deprecated
+
+- `Uri::resolve` in favor of `UriResolver::resolve`
+- `Uri::removeDotSegments` in favor of `UriResolver::removeDotSegments`
+
+### Fixed
+
+- `Stream::read` when length parameter <= 0.
+- `copy_to_stream` reads bytes in chunks instead of `maxLen` into memory.
+- `ServerRequest::getUriFromGlobals` when `Host` header contains port.
+- Compatibility of URIs with `file` scheme and empty host.
+
+
+## [1.3.1] - 2016-06-25
+
+### Fixed
+
+- `Uri::__toString` for network path references, e.g. `//example.org`.
+- Missing lowercase normalization for host.
+- Handling of URI components in case they are `'0'` in a lot of places,
+  e.g. as a user info password.
+- `Uri::withAddedHeader` to correctly merge headers with different case.
+- Trimming of header values in `Uri::withAddedHeader`. Header values may
+  be surrounded by whitespace which should be ignored according to RFC 7230
+  Section 3.2.4. This does not apply to header names.
+- `Uri::withAddedHeader` with an array of header values.
+- `Uri::resolve` when base path has no slash and handling of fragment.
+- Handling of encoding in `Uri::with(out)QueryValue` so one can pass the
+  key/value both in encoded as well as decoded form to those methods. This is
+  consistent with withPath, withQuery etc.
+- `ServerRequest::withoutAttribute` when attribute value is null.
+
+
+## [1.3.0] - 2016-04-13
+
+### Added
+
+- Remaining interfaces needed for full PSR7 compatibility
+  (ServerRequestInterface, UploadedFileInterface, etc.).
+- Support for stream_for from scalars.
+
+### Changed
+
+- Can now extend Uri.
+
+### Fixed
+- A bug in validating request methods by making it more permissive.
+
+
+## [1.2.3] - 2016-02-18
+
+### Fixed
+
+- Support in `GuzzleHttp\Psr7\CachingStream` for seeking forward on remote
+  streams, which can sometimes return fewer bytes than requested with `fread`.
+- Handling of gzipped responses with FNAME headers.
+
+
+## [1.2.2] - 2016-01-22
+
+### Added
+
+- Support for URIs without any authority.
+- Support for HTTP 451 'Unavailable For Legal Reasons.'
+- Support for using '0' as a filename.
+- Support for including non-standard ports in Host headers.
+
+
+## [1.2.1] - 2015-11-02
+
+### Changes
+
+- Now supporting negative offsets when seeking to SEEK_END.
+
+
+## [1.2.0] - 2015-08-15
+
+### Changed
+
+- Body as `"0"` is now properly added to a response.
+- Now allowing forward seeking in CachingStream.
+- Now properly parsing HTTP requests that contain proxy targets in
+  `parse_request`.
+- functions.php is now conditionally required.
+- user-info is no longer dropped when resolving URIs.
+
+
+## [1.1.0] - 2015-06-24
+
+### Changed
+
+- URIs can now be relative.
+- `multipart/form-data` headers are now overridden case-insensitively.
+- URI paths no longer encode the following characters because they are allowed
+  in URIs: "(", ")", "*", "!", "'"
+- A port is no longer added to a URI when the scheme is missing and no port is
+  present.
+
+
+## 1.0.0 - 2015-05-19
+
+Initial release.
+
+Currently unsupported:
+
+- `Psr\Http\Message\ServerRequestInterface`
+- `Psr\Http\Message\UploadedFileInterface`

+# PSR-7 Message Implementation
+
+This repository contains a full [PSR-7](http://www.php-fig.org/psr/psr-7/)
+message implementation, several stream decorators, and some helpful
+functionality like query string parsing.
+
+
+[![Build Status](https://travis-ci.org/guzzle/psr7.svg?branch=master)](https://travis-ci.org/guzzle/psr7)
+
+
+# Stream implementation
+
+This package comes with a number of stream implementations and stream
+decorators.
+
+
+## AppendStream
+
+`GuzzleHttp\Psr7\AppendStream`
+
+Reads from multiple streams, one after the other.
+
+```php
+use GuzzleHttp\Psr7;
+
+$a = Psr7\stream_for('abc, ');
+$b = Psr7\stream_for('123.');
+$composed = new Psr7\AppendStream([$a, $b]);
+
+$composed->addStream(Psr7\stream_for(' Above all listen to me'));
+
+echo $composed; // abc, 123. Above all listen to me.
+```
+
+
+## BufferStream
+
+`GuzzleHttp\Psr7\BufferStream`
+
+Provides a buffer stream that can be written to fill a buffer, and read
+from to remove bytes from the buffer.
+
+This stream returns a "hwm" metadata value that tells upstream consumers
+what the configured high water mark of the stream is, or the maximum
+preferred size of the buffer.
+
+```php
+use GuzzleHttp\Psr7;
+
+// When more than 1024 bytes are in the buffer, it will begin returning
+// false to writes. This is an indication that writers should slow down.
+$buffer = new Psr7\BufferStream(1024);
+```
+
+
+## CachingStream
+
+The CachingStream is used to allow seeking over previously read bytes on
+non-seekable streams. This can be useful when transferring a non-seekable
+entity body fails due to needing to rewind the stream (for example, resulting
+from a redirect). Data that is read from the remote stream will be buffered in
+a PHP temp stream so that previously read bytes are cached first in memory,
+then on disk.
+
+```php
+use GuzzleHttp\Psr7;
+
+$original = Psr7\stream_for(fopen('http://www.google.com', 'r'));
+$stream = new Psr7\CachingStream($original);
+
+$stream->read(1024);
+echo $stream->tell();
+// 1024
+
+$stream->seek(0);
+echo $stream->tell();
+// 0
+```
+
+
+## DroppingStream
+
+`GuzzleHttp\Psr7\DroppingStream`
+
+Stream decorator that begins dropping data once the size of the underlying
+stream becomes too full.
+
+```php
+use GuzzleHttp\Psr7;
+
+// Create an empty stream
+$stream = Psr7\stream_for();
+
+// Start dropping data when the stream has more than 10 bytes
+$dropping = new Psr7\DroppingStream($stream, 10);
+
+$dropping->write('01234567890123456789');
+echo $stream; // 0123456789
+```
+
+
+## FnStream
+
+`GuzzleHttp\Psr7\FnStream`
+
+Compose stream implementations based on a hash of functions.
+
+Allows for easy testing and extension of a provided stream without needing
+to create a concrete class for a simple extension point.
+
+```php
+
+use GuzzleHttp\Psr7;
+
+$stream = Psr7\stream_for('hi');
+$fnStream = Psr7\FnStream::decorate($stream, [
+    'rewind' => function () use ($stream) {
+        echo 'About to rewind - ';
+        $stream->rewind();
+        echo 'rewound!';
+    }
+]);
+
+$fnStream->rewind();
+// Outputs: About to rewind - rewound!
+```
+
+
+## InflateStream
+
+`GuzzleHttp\Psr7\InflateStream`
+
+Uses PHP's zlib.inflate filter to inflate deflate or gzipped content.
+
+This stream decorator skips the first 10 bytes of the given stream to remove
+the gzip header, converts the provided stream to a PHP stream resource,
+then appends the zlib.inflate filter. The stream is then converted back
+to a Guzzle stream resource to be used as a Guzzle stream.
+
+
+## LazyOpenStream
+
+`GuzzleHttp\Psr7\LazyOpenStream`
+
+Lazily reads or writes to a file that is opened only after an IO operation
+take place on the stream.
+
+```php
+use GuzzleHttp\Psr7;
+
+$stream = new Psr7\LazyOpenStream('/path/to/file', 'r');
+// The file has not yet been opened...
+
+echo $stream->read(10);
+// The file is opened and read from only when needed.
+```
+
+
+## LimitStream
+
+`GuzzleHttp\Psr7\LimitStream`
+
+LimitStream can be used to read a subset or slice of an existing stream object.
+This can be useful for breaking a large file into smaller pieces to be sent in
+chunks (e.g. Amazon S3's multipart upload API).
+
+```php
+use GuzzleHttp\Psr7;
+
+$original = Psr7\stream_for(fopen('/tmp/test.txt', 'r+'));
+echo $original->getSize();
+// >>> 1048576
+
+// Limit the size of the body to 1024 bytes and start reading from byte 2048
+$stream = new Psr7\LimitStream($original, 1024, 2048);
+echo $stream->getSize();
+// >>> 1024
+echo $stream->tell();
+// >>> 0
+```
+
+
+## MultipartStream
+
+`GuzzleHttp\Psr7\MultipartStream`
+
+Stream that when read returns bytes for a streaming multipart or
+multipart/form-data stream.
+
+
+## NoSeekStream
+
+`GuzzleHttp\Psr7\NoSeekStream`
+
+NoSeekStream wraps a stream and does not allow seeking.
+
+```php
+use GuzzleHttp\Psr7;
+
+$original = Psr7\stream_for('foo');
+$noSeek = new Psr7\NoSeekStream($original);
+
+echo $noSeek->read(3);
+// foo
+var_export($noSeek->isSeekable());
+// false
+$noSeek->seek(0);
+var_export($noSeek->read(3));
+// NULL
+```
+
+
+## PumpStream
+
+`GuzzleHttp\Psr7\PumpStream`
+
+Provides a read only stream that pumps data from a PHP callable.
+
+When invoking the provided callable, the PumpStream will pass the amount of
+data requested to read to the callable. The callable can choose to ignore
+this value and return fewer or more bytes than requested. Any extra data
+returned by the provided callable is buffered internally until drained using
+the read() function of the PumpStream. The provided callable MUST return
+false when there is no more data to read.
+
+
+## Implementing stream decorators
+
+Creating a stream decorator is very easy thanks to the
+`GuzzleHttp\Psr7\StreamDecoratorTrait`. This trait provides methods that
+implement `Psr\Http\Message\StreamInterface` by proxying to an underlying
+stream. Just `use` the `StreamDecoratorTrait` and implement your custom
+methods.
+
+For example, let's say we wanted to call a specific function each time the last
+byte is read from a stream. This could be implemented by overriding the
+`read()` method.
+
+```php
+use Psr\Http\Message\StreamInterface;
+use GuzzleHttp\Psr7\StreamDecoratorTrait;
+
+class EofCallbackStream implements StreamInterface
+{
+    use StreamDecoratorTrait;
+
+    private $callback;
+
+    public function __construct(StreamInterface $stream, callable $cb)
+    {
+        $this->stream = $stream;
+        $this->callback = $cb;
+    }
+
+    public function read($length)
+    {
+        $result = $this->stream->read($length);
+
+        // Invoke the callback when EOF is hit.
+        if ($this->eof()) {
+            call_user_func($this->callback);
+        }
+
+        return $result;
+    }
+}
+```
+
+This decorator could be added to any existing stream and used like so:
+
+```php
+use GuzzleHttp\Psr7;
+
+$original = Psr7\stream_for('foo');
+
+$eofStream = new EofCallbackStream($original, function () {
+    echo 'EOF!';
+});
+
+$eofStream->read(2);
+$eofStream->read(1);
+// echoes "EOF!"
+$eofStream->seek(0);
+$eofStream->read(3);
+// echoes "EOF!"
+```
+
+
+## PHP StreamWrapper
+
+You can use the `GuzzleHttp\Psr7\StreamWrapper` class if you need to use a
+PSR-7 stream as a PHP stream resource.
+
+Use the `GuzzleHttp\Psr7\StreamWrapper::getResource()` method to create a PHP
+stream from a PSR-7 stream.
+
+```php
+use GuzzleHttp\Psr7\StreamWrapper;
+
+$stream = GuzzleHttp\Psr7\stream_for('hello!');
+$resource = StreamWrapper::getResource($stream);
+echo fread($resource, 6); // outputs hello!
+```
+
+
+# Function API
+
+There are various functions available under the `GuzzleHttp\Psr7` namespace.
+
+
+## `function str`
+
+`function str(MessageInterface $message)`
+
+Returns the string representation of an HTTP message.
+
+```php
+$request = new GuzzleHttp\Psr7\Request('GET', 'http://example.com');
+echo GuzzleHttp\Psr7\str($request);
+```
+
+
+## `function uri_for`
+
+`function uri_for($uri)`
+
+This function accepts a string or `Psr\Http\Message\UriInterface` and returns a
+UriInterface for the given value. If the value is already a `UriInterface`, it
+is returned as-is.
+
+```php
+$uri = GuzzleHttp\Psr7\uri_for('http://example.com');
+assert($uri === GuzzleHttp\Psr7\uri_for($uri));
+```
+
+
+## `function stream_for`
+
+`function stream_for($resource = '', array $options = [])`
+
+Create a new stream based on the input type.
+
+Options is an associative array that can contain the following keys:
+
+* - metadata: Array of custom metadata.
+* - size: Size of the stream.
+
+This method accepts the following `$resource` types:
+
+- `Psr\Http\Message\StreamInterface`: Returns the value as-is.
+- `string`: Creates a stream object that uses the given string as the contents.
+- `resource`: Creates a stream object that wraps the given PHP stream resource.
+- `Iterator`: If the provided value implements `Iterator`, then a read-only
+  stream object will be created that wraps the given iterable. Each time the
+  stream is read from, data from the iterator will fill a buffer and will be
+  continuously called until the buffer is equal to the requested read size.
+  Subsequent read calls will first read from the buffer and then call `next`
+  on the underlying iterator until it is exhausted.
+- `object` with `__toString()`: If the object has the `__toString()` method,
+  the object will be cast to a string and then a stream will be returned that
+  uses the string value.
+- `NULL`: When `null` is passed, an empty stream object is returned.
+- `callable` When a callable is passed, a read-only stream object will be
+  created that invokes the given callable. The callable is invoked with the
+  number of suggested bytes to read. The callable can return any number of
+  bytes, but MUST return `false` when there is no more data to return. The
+  stream object that wraps the callable will invoke the callable until the
+  number of requested bytes are available. Any additional bytes will be
+  buffered and used in subsequent reads.
+
+```php
+$stream = GuzzleHttp\Psr7\stream_for('foo');
+$stream = GuzzleHttp\Psr7\stream_for(fopen('/path/to/file', 'r'));
+
+$generator = function ($bytes) {
+    for ($i = 0; $i < $bytes; $i++) {
+        yield ' ';
+    }
+}
+
+$stream = GuzzleHttp\Psr7\stream_for($generator(100));
+```
+
+
+## `function parse_header`
+
+`function parse_header($header)`
+
+Parse an array of header values containing ";" separated data into an array of
+associative arrays representing the header key value pair data of the header.
+When a parameter does not contain a value, but just contains a key, this
+function will inject a key with a '' string value.
+
+
+## `function normalize_header`
+
+`function normalize_header($header)`
+
+Converts an array of header values that may contain comma separated headers
+into an array of headers with no comma separated values.
+
+
+## `function modify_request`
+
+`function modify_request(RequestInterface $request, array $changes)`
+
+Clone and modify a request with the given changes. This method is useful for
+reducing the number of clones needed to mutate a message.
+
+The changes can be one of:
+
+- method: (string) Changes the HTTP method.
+- set_headers: (array) Sets the given headers.
+- remove_headers: (array) Remove the given headers.
+- body: (mixed) Sets the given body.
+- uri: (UriInterface) Set the URI.
+- query: (string) Set the query string value of the URI.
+- version: (string) Set the protocol version.
+
+
+## `function rewind_body`
+
+`function rewind_body(MessageInterface $message)`
+
+Attempts to rewind a message body and throws an exception on failure. The body
+of the message will only be rewound if a call to `tell()` returns a value other
+than `0`.
+
+
+## `function try_fopen`
+
+`function try_fopen($filename, $mode)`
+
+Safely opens a PHP stream resource using a filename.
+
+When fopen fails, PHP normally raises a warning. This function adds an error
+handler that checks for errors and throws an exception instead.
+
+
+## `function copy_to_string`
+
+`function copy_to_string(StreamInterface $stream, $maxLen = -1)`
+
+Copy the contents of a stream into a string until the given number of bytes
+have been read.
+
+
+## `function copy_to_stream`
+
+`function copy_to_stream(StreamInterface $source, StreamInterface $dest, $maxLen = -1)`
+
+Copy the contents of a stream into another stream until the given number of
+bytes have been read.
+
+
+## `function hash`
+
+`function hash(StreamInterface $stream, $algo, $rawOutput = false)`
+
+Calculate a hash of a Stream. This method reads the entire stream to calculate
+a rolling hash (based on PHP's hash_init functions).
+
+
+## `function readline`
+
+`function readline(StreamInterface $stream, $maxLength = null)`
+
+Read a line from the stream up to the maximum allowed buffer length.
+
+
+## `function parse_request`
+
+`function parse_request($message)`
+
+Parses a request message string into a request object.
+
+
+## `function parse_response`
+
+`function parse_response($message)`
+
+Parses a response message string into a response object.
+
+
+## `function parse_query`
+
+`function parse_query($str, $urlEncoding = true)`
+
+Parse a query string into an associative array.
+
+If multiple values are found for the same key, the value of that key value pair
+will become an array. This function does not parse nested PHP style arrays into
+an associative array (e.g., `foo[a]=1&foo[b]=2` will be parsed into
+`['foo[a]' => '1', 'foo[b]' => '2']`).
+
+
+## `function build_query`
+
+`function build_query(array $params, $encoding = PHP_QUERY_RFC3986)`
+
+Build a query string from an array of key value pairs.
+
+This function can use the return value of parse_query() to build a query string.
+This function does not modify the provided keys when an array is encountered
+(like http_build_query would).
+
+
+## `function mimetype_from_filename`
+
+`function mimetype_from_filename($filename)`
+
+Determines the mimetype of a file by looking at its extension.
+
+
+## `function mimetype_from_extension`
+
+`function mimetype_from_extension($extension)`
+
+Maps a file extensions to a mimetype.

+
+# Additional URI Methods
+
+Aside from the standard `Psr\Http\Message\UriInterface` implementation in form of the `GuzzleHttp\Psr7\Uri` class,
+this library also provides additional functionality when working with URIs as static methods.
+
+## URI Types
+
+An instance of `Psr\Http\Message\UriInterface` can either be an absolute URI or a relative reference.
+An absolute URI has a scheme. A relative reference is used to express a URI relative to another URI,
+the base URI. Relative references can be divided into several forms according to
+[RFC 3986 Section 4.2](https://tools.ietf.org/html/rfc3986#section-4.2):
+
+- network-path references, e.g. `//example.com/path`
+- absolute-path references, e.g. `/path`
+- relative-path references, e.g. `subpath`
+
+The following methods can be used to identify the type of the URI.
+
+### `GuzzleHttp\Psr7\Uri::isAbsolute`
+
+`public static function isAbsolute(UriInterface $uri): bool`
+
+Whether the URI is absolute, i.e. it has a scheme.
+
+### `GuzzleHttp\Psr7\Uri::isNetworkPathReference`
+
+`public static function isNetworkPathReference(UriInterface $uri): bool`
+
+Whether the URI is a network-path reference. A relative reference that begins with two slash characters is
+termed an network-path reference.
+
+### `GuzzleHttp\Psr7\Uri::isAbsolutePathReference`
+
+`public static function isAbsolutePathReference(UriInterface $uri): bool`
+
+Whether the URI is a absolute-path reference. A relative reference that begins with a single slash character is
+termed an absolute-path reference.
+
+### `GuzzleHttp\Psr7\Uri::isRelativePathReference`
+
+`public static function isRelativePathReference(UriInterface $uri): bool`
+
+Whether the URI is a relative-path reference. A relative reference that does not begin with a slash character is
+termed a relative-path reference.
+
+### `GuzzleHttp\Psr7\Uri::isSameDocumentReference`
+
+`public static function isSameDocumentReference(UriInterface $uri, UriInterface $base = null): bool`
+
+Whether the URI is a same-document reference. A same-document reference refers to a URI that is, aside from its
+fragment component, identical to the base URI. When no base URI is given, only an empty URI reference
+(apart from its fragment) is considered a same-document reference.
+
+## URI Components
+
+Additional methods to work with URI components.
+
+### `GuzzleHttp\Psr7\Uri::isDefaultPort`
+
+`public static function isDefaultPort(UriInterface $uri): bool`
+
+Whether the URI has the default port of the current scheme. `Psr\Http\Message\UriInterface::getPort` may return null
+or the standard port. This method can be used independently of the implementation.
+
+### `GuzzleHttp\Psr7\Uri::composeComponents`
+
+`public static function composeComponents($scheme, $authority, $path, $query, $fragment): string`
+
+Composes a URI reference string from its various components according to
+[RFC 3986 Section 5.3](https://tools.ietf.org/html/rfc3986#section-5.3). Usually this method does not need to be called
+manually but instead is used indirectly via `Psr\Http\Message\UriInterface::__toString`.
+
+### `GuzzleHttp\Psr7\Uri::fromParts`
+
+`public static function fromParts(array $parts): UriInterface`
+
+Creates a URI from a hash of [`parse_url`](http://php.net/manual/en/function.parse-url.php) components.
+
+
+### `GuzzleHttp\Psr7\Uri::withQueryValue`
+
+`public static function withQueryValue(UriInterface $uri, $key, $value): UriInterface`
+
+Creates a new URI with a specific query string value. Any existing query string values that exactly match the
+provided key are removed and replaced with the given key value pair. A value of null will set the query string
+key without a value, e.g. "key" instead of "key=value".
+
+### `GuzzleHttp\Psr7\Uri::withQueryValues`
+
+`public static function withQueryValues(UriInterface $uri, array $keyValueArray): UriInterface`
+
+Creates a new URI with multiple query string values. It has the same behavior as `withQueryValue()` but for an
+associative array of key => value.
+
+### `GuzzleHttp\Psr7\Uri::withoutQueryValue`
+
+`public static function withoutQueryValue(UriInterface $uri, $key): UriInterface`
+
+Creates a new URI with a specific query string value removed. Any existing query string values that exactly match the
+provided key are removed.
+
+## Reference Resolution
+
+`GuzzleHttp\Psr7\UriResolver` provides methods to resolve a URI reference in the context of a base URI according
+to [RFC 3986 Section 5](https://tools.ietf.org/html/rfc3986#section-5). This is for example also what web browsers
+do when resolving a link in a website based on the current request URI.
+
+### `GuzzleHttp\Psr7\UriResolver::resolve`
+
+`public static function resolve(UriInterface $base, UriInterface $rel): UriInterface`
+
+Converts the relative URI into a new URI that is resolved against the base URI.
+
+### `GuzzleHttp\Psr7\UriResolver::removeDotSegments`
+
+`public static function removeDotSegments(string $path): string`
+
+Removes dot segments from a path and returns the new path according to
+[RFC 3986 Section 5.2.4](https://tools.ietf.org/html/rfc3986#section-5.2.4).
+
+### `GuzzleHttp\Psr7\UriResolver::relativize`
+
+`public static function relativize(UriInterface $base, UriInterface $target): UriInterface`
+
+Returns the target URI as a relative reference from the base URI. This method is the counterpart to resolve():
+
+```php
+(string) $target === (string) UriResolver::resolve($base, UriResolver::relativize($base, $target))
+```
+
+One use-case is to use the current request URI as base URI and then generate relative links in your documents
+to reduce the document size or offer self-contained downloadable document archives.
+
+```php
+$base = new Uri('http://example.com/a/b/');
+echo UriResolver::relativize($base, new Uri('http://example.com/a/b/c'));  // prints 'c'.
+echo UriResolver::relativize($base, new Uri('http://example.com/a/x/y'));  // prints '../x/y'.
+echo UriResolver::relativize($base, new Uri('http://example.com/a/b/?q')); // prints '?q'.
+echo UriResolver::relativize($base, new Uri('http://example.org/a/b/'));   // prints '//example.org/a/b/'.
+```
+
+## Normalization and Comparison
+
+`GuzzleHttp\Psr7\UriNormalizer` provides methods to normalize and compare URIs according to
+[RFC 3986 Section 6](https://tools.ietf.org/html/rfc3986#section-6).
+
+### `GuzzleHttp\Psr7\UriNormalizer::normalize`
+
+`public static function normalize(UriInterface $uri, $flags = self::PRESERVING_NORMALIZATIONS): UriInterface`
+
+Returns a normalized URI. The scheme and host component are already normalized to lowercase per PSR-7 UriInterface.
+This methods adds additional normalizations that can be configured with the `$flags` parameter which is a bitmask
+of normalizations to apply. The following normalizations are available:
+
+- `UriNormalizer::PRESERVING_NORMALIZATIONS`
+
+    Default normalizations which only include the ones that preserve semantics.
+
+- `UriNormalizer::CAPITALIZE_PERCENT_ENCODING`
+
+    All letters within a percent-encoding triplet (e.g., "%3A") are case-insensitive, and should be capitalized.
+
+    Example: `http://example.org/a%c2%b1b` → `http://example.org/a%C2%B1b`
+
+- `UriNormalizer::DECODE_UNRESERVED_CHARACTERS`
+
+    Decodes percent-encoded octets of unreserved characters. For consistency, percent-encoded octets in the ranges of
+    ALPHA (%41–%5A and %61–%7A), DIGIT (%30–%39), hyphen (%2D), period (%2E), underscore (%5F), or tilde (%7E) should
+    not be created by URI producers and, when found in a URI, should be decoded to their corresponding unreserved
+    characters by URI normalizers.
+
+    Example: `http://example.org/%7Eusern%61me/` → `http://example.org/~username/`
+
+- `UriNormalizer::CONVERT_EMPTY_PATH`
+
+    Converts the empty path to "/" for http and https URIs.
+
+    Example: `http://example.org` → `http://example.org/`
+
+- `UriNormalizer::REMOVE_DEFAULT_HOST`
+
+    Removes the default host of the given URI scheme from the URI. Only the "file" scheme defines the default host
+    "localhost". All of `file:/myfile`, `file:///myfile`, and `file://localhost/myfile` are equivalent according to
+    RFC 3986.
+
+    Example: `file://localhost/myfile` → `file:///myfile`
+
+- `UriNormalizer::REMOVE_DEFAULT_PORT`
+
+    Removes the default port of the given URI scheme from the URI.
+
+    Example: `http://example.org:80/` → `http://example.org/`
+
+- `UriNormalizer::REMOVE_DOT_SEGMENTS`
+
+    Removes unnecessary dot-segments. Dot-segments in relative-path references are not removed as it would
+    change the semantics of the URI reference.
+
+    Example: `http://example.org/../a/b/../c/./d.html` → `http://example.org/a/c/d.html`
+
+- `UriNormalizer::REMOVE_DUPLICATE_SLASHES`
+
+    Paths which include two or more adjacent slashes are converted to one. Webservers usually ignore duplicate slashes
+    and treat those URIs equivalent. But in theory those URIs do not need to be equivalent. So this normalization
+    may change the semantics. Encoded slashes (%2F) are not removed.
+
+    Example: `http://example.org//foo///bar.html` → `http://example.org/foo/bar.html`
+
+- `UriNormalizer::SORT_QUERY_PARAMETERS`
+
+    Sort query parameters with their values in alphabetical order. However, the order of parameters in a URI may be
+    significant (this is not defined by the standard). So this normalization is not safe and may change the semantics
+    of the URI.
+
+    Example: `?lang=en&article=fred` → `?article=fred&lang=en`
+
+### `GuzzleHttp\Psr7\UriNormalizer::isEquivalent`
+
+`public static function isEquivalent(UriInterface $uri1, UriInterface $uri2, $normalizations = self::PRESERVING_NORMALIZATIONS): bool`
+
+Whether two URIs can be considered equivalent. Both URIs are normalized automatically before comparison with the given
+`$normalizations` bitmask. The method also accepts relative URI references and returns true when they are equivalent.
+This of course assumes they will be resolved against the same base URI. If this is not the case, determination of
+equivalence or difference of relative references does not mean anything.

+# LazyJsonMapper
+
+## Advanced, intelligent & automatic object-oriented JSON containers for PHP.
+
+Implements a highly efficient, automatic, object-oriented and lightweight
+(memory-wise) JSON data container. It provides intelligent data conversion
+and parsing, to give you a nice, reliable interface to your JSON data,
+without having to worry about doing any of the tedious parsing yourself.
+
+### Features:
+
+- Provides a completely object-oriented interface to all of your JSON data.
+
+- Automatically maps complex, nested JSON data structures onto real PHP
+  objects, with total support for nested objects and multi-level arrays.
+
+- Extremely optimized for very high performance and very low memory usage.
+  Much lower than other PHP JSON mappers that people have used in the past.
+
+  For example, normal PHP objects with manually defined `$properties`, which
+  is what's used by _other_ JSON mappers, will consume memory for every
+  property even if that property wasn't in the JSON data (is a `NULL`). Our
+  system on the other hand takes up ZERO bytes of RAM for any properties
+  that don't exist in the current object's JSON data!
+
+- Automatically provides "direct virtual properties", which lets you
+  interact with the JSON data as if it were regular object properties,
+  such as `echo $item->some_value` and `$item->some_value = 'foo'`.
+
+  The virtual properties can be disabled via an option.
+
+- Automatically provides object-oriented "virtual functions", which let you
+  interact with the data in a fully object-oriented way via functions such
+  as `$item->getSomeValue()` and `$item->setSomeValue('foo')`. We support a
+  large range of different functions for manipulating the JSON data, and you
+  can see a list of all available function names for all of your properties
+  by simply running `$item->printPropertyDescriptions()`.
+
+  The virtual functions can be disabled via an option.
+
+- Includes the `LazyDoctor` tool, which _automatically_ documents all of
+  your `LazyJsonMapper`-based classes so that their virtual properties and
+  functions become _fully_ visible to your IDE and to various intelligent
+  code analysis tools. It also performs class diagnostics by compiling all
+  of your class property maps, which means that you can be 100% sure that
+  all of your maps are valid (compilable) if this tool runs successfully.
+
+- We provide a complete, internal API which your subclasses can use to
+  interact with the data inside of the JSON container. This allows you to
+  easily override the automatic functions or create additional functions
+  for your objects. To override core functions, just define a function with
+  the exact same name on your object and make it do whatever you want to.
+
+  Here are some examples of function overriding:
+
+    ```php
+    public function getFoo()
+    {
+        // try to read property, and handle a special "current_time" value.
+        $value = $this->_getProperty('foo');
+        if ($value === 'current_time') { return time(); }
+        return $value;
+    }
+    public function setFoo(
+        $value)
+    {
+        // if they try to set value to "md5", we use a special value instead
+        if ($value === 'md5') { $value = md5(time()); }
+        return $this->_setProperty('foo', $value);
+    }
+    ```
+
+- All mapping/data conversion is done "lazily", on a per-property basis.
+  When you access a property, that specific property is mapped/converted to
+  the proper type as defined by your class property map. No time or memory
+  is wasted converting properties that you never touch.
+
+- Strong type-system. The class property map controls the exact types and
+  array depths. You can fully trust that the data you get/set will match
+  your specifications. Invalid data that mismatches the spec is impossible.
+
+- Advanced settings system. Everything is easily configured via PHP class
+  constants, which means that your class-settings are stateless (there's no
+  need for any special "settings/mapper object" to keep track of settings),
+  and that all settings are immutable constants (which means that they are
+  reliable and can never mutate at runtime, so that you can fully trust that
+  classes will always behave as-defined in their code).
+
+  If you want to override multiple core settings identically for all of your
+  classes, then simply create a subclass of `LazyJsonMapper` and configure
+  all of your settings on that, and then derive all of your other classes
+  from your re-configured subclass!
+
+- The world's most advanced mapper definition system. Your class property
+  maps are defined in an easy PHPdoc-style format, and support multilevel
+  arrays (such as `int[][]` for "an array of arrays of ints"), relative
+  types (so you can map properties to classes/objects that are relative to
+  the namespace of the class property map), parent inheritance (all of your
+  parent `extends`-hierarchy's maps will be included in your final property
+  map) and even multiple inheritance (you can literally "import" an infinite
+  number of other maps into your class, which don't come from your own
+  parent `extends`-hierarchy).
+
+- Inheriting properties from parent classes or importing properties from
+  other classes is a zero-cost operation thanks to how efficient our
+  property map compiler is. So feel free to import everything you need.
+  You can even use this system to create importable classes that just hold
+  "collections" of shared properties, which you import into other classes.
+
+- The class property maps are compiled a single time per-class at runtime,
+  the first time a class is used. The compilation process fully verifies
+  and compiles all property definitions, all parent maps, all inherited
+  maps, and all maps of all classes you link properties to.
+
+  If there are any compilation problems due to a badly written map anywhere
+  in your hierarchy, you will be shown the exact problem in great detail.
+
+  In case of success, the compiled and verified maps are all stored in an
+  incredibly memory-efficient format in a global cache which is shared by
+  your whole PHP runtime, which means that anything in your code or in any
+  other libraries which accesses the same classes will all share the cached
+  compilations of those classes, for maximum memory efficiency.
+
+- You are also able to access JSON properties that haven't been defined in
+  the class property map. In that case, they are treated as undefined and
+  untyped (`mixed`) and there won't be any automatic type-conversion of such
+  properties, but it can still be handy in a pinch.
+
+- There are lots of data export/output options for your object's JSON data,
+  to get it back out of the object again: As a multi-level array, as nested
+  stdClass objects, or as a JSON string representation of your object.
+
+- We include a whole assortment of incredibly advanced debugging features:
+
+  You can run the constructor with `$requireAnalysis` to ensure that all
+  of your JSON data is successfully mapped according to your class property
+  map, and that you haven't missed defining any properties that exist in the
+  data. In case of any problems, the analysis message will give you a full
+  list of all problems encountered in your entire JSON data hierarchy.
+
+  For your class property maps themselves, you can run functions such as
+  `printPropertyDescriptions()` to see a complete list of all properties and
+  how they are defined. This helps debug your class inheritance and imports
+  to visually see what your final class map looks like, and it also helps
+  users see all available properties and all of their virtual functions.
+
+  And for the JSON data, you can use functions such as `printJson()` to get
+  a beautiful view of all internal JSON data, which is incredibly helpful
+  when you (or your users) need to figure out what's available inside the
+  current object instance's data storage.
+
+- A fine-grained and logical exception-system which ensures that you can
+  always trust the behavior of your objects and can catch problems easily.
+  And everything we throw is _always_ based on `LazyJsonMapperException`,
+  which means that you can simply catch that single "root" exception
+  whenever you don't care about fine-grained differentiation.
+
+- Clean and modular code ensures stability and future extensibility.
+
+- Deep code documentation explains everything you could ever wonder about.
+
+- Lastly, we implement super-efficient object serialization. Everything is
+  stored in a tightly packed format which minimizes data size when you need
+  to transfer your objects between runtimes.

+/*
+ * The Lazy Doctor.
+ *
+ * This tool automatically builds up-to-date class documentation for all classes
+ * that derive from LazyJsonMapper, and documents their virtual properties and
+ * functions by adding "@property" and "@method" declarations to their class
+ * PHPdoc blocks. That documentation is necessary for things like code analysis
+ * tools and IDE autocomplete for all of your virtual properties/functions!
+ *
+ * LazyDoctor also performs class diagnostics: It compiles the class property
+ * maps of _all_ of your LazyJsonMapper-based classes, which means that you can
+ * be 100% sure that all of your maps are valid if this tool runs successfully.
+ *
+ * To see all available options, type "./vendor/bin/lazydoctor --help".
+ *
+ * To begin, simply point the "--composer" option at the "composer.json" file
+ * for your project. Just be aware that your project MUST be based on PSR-4
+ * autoloading, with ONE OR MORE defined autoload-namespaces in "composer.json".
+ *
+ * You can read more about PSR-4 autoloading at the official Composer site:
+ *
+ * https://getcomposer.org/doc/04-schema.md#autoload
+ *
+ * This tool will ONLY parse classes that properly follow PSR-4 autoloading!
+ *
+ * In addition to the composer-file, you'll also have to specify whether you
+ * want to document virtual "--properties", virtual "--functions", or BOTH.
+ * Note that we'll ONLY document them when the individual classes support that
+ * kind of access (when it hasn't disabled its class-option for that feature).
+ *
+ * If you don't provide any documentation flags, we'll instead REMOVE all of
+ * the current class "virtual @property/@method" documentation. That can be
+ * useful for restoring your files if you don't want to document them anymore.
+ *
+ * You should also be aware of "--document-overridden", which will document
+ * virtual properties or functions even if they're already manually defined
+ * (overridden) by the class or its parents. That can be useful if you want to
+ * ensure that you ALWAYS document the virtual properties/functions in all of
+ * your class files even when it has been overridden somewhere. In that case,
+ * you should ensure that your overridden properties/functions have the SAME or
+ * a COMPATIBLE signature & return value, so their auto-docs are still correct.
+ *
+ * Tip: You can use the "--validate-only" param to check docs without writing to
+ * disk. That can be useful when making a non-destructive Git "pre-commit hook"
+ * to validate your repo and ensure that all files have updated documentation!
+ *
+ * This script always uses exit codes to indicate success. A non-zero exit code
+ * indicates that some files needed new class docs (in "--validate-only" mode),
+ * or that there was a general problem while processing.
+ *
+ * Lastly, you may appreciate the ability to silence all unimportant status
+ * messages! To do so, simply use ">/dev/null" to send STDOUT to the void...
+ * That way you'll ONLY see critical status messages during the processing.

+// tests during development of LazyJsonMapper... I barely even cared about
+// grammar since this file was just meant to dump a bunch of tests in and not
+// meant for public use. But it has so many extremely important tests that
+// cover all kinds of common and unusual scenarios. Several of the tests may
+// be outdated and test details that later changed during development. So
+// everything below needs to be carefully revised.
+//
+// We REALLY SHOULD rewrite everything as clean and organized PHPUnit tests...
+// if SOMEONE has the energy...
+//
+// PS: If anyone is using this library for commercial purposes, then a nice way
+// to contribute back as a "thank you!" would be to manually go through
+// everything below and rewrite relevant tests as beautiful PHPunit tests. :-)
+// If someone wants to contribute, you can do the test-rewrite step by step and
+// won't have to do everything all at once. ;-)

+/*
+ * I created these stack-based array loop algorithms for fun, just to try out
+ * an idea I had in mind. They are algorithms for iterating through multi-level
+ * arrays without needing any recursive function calls. And they are fully
+ * capable of tracking the current array-depth that they're operating at...
+ *
+ * These are the algorithms I tested:
+ * - RecursiveIteratorIterator = PHP's built-in object-based iterator library
+ * - array_flat_topdown_traverse = my stack-based algorithm v1
+ * - array_flat_topdown_traverse2 = my stack-based algorithm v2 (optimized)
+ * - array_recursive_traverse = simple recursive function calls
+ *
+ * The recursive function calls add 1 extra level to the call-stack for every
+ * deeper array depth-level that it enters.
+ *
+ * Therefore, I tested everything with test-data that contained array-depth 6
+ * (that's usually max in normal JSON data), 50 (rare), 500 (insane) and finally
+ * 5000 (hellish). The latter means that the recursive function calls-stack will
+ * reach a depth of 5000 recursive calls inside of each other. Hell indeed.
+ *
+ * The algorithms were a success; MASSIVELY beating `RecursiveIteratorIterator`
+ * from PHP's standard library by a factor of being almost 10x faster than it.
+ *
+ * Here's the fun thing, though: Simple, old-school recursive function-calls
+ * beats even my algorithm by a factor of being 2x faster!
+ *
+ * As for memory usage? The 500-levels deep recursive function calls didn't even
+ * make a noticeable blip on the radar...! They don't cause any stack memory
+ * overflows. On PHP5, this WHOLE test-script used 7.4 MB at peak while running
+ * all of the various tests. On PHP7, it used 4.7 MB at peak. And that's for the
+ * whole PHP binary, its runtime, etc! I didn't test the 5000-levels deep, but
+ * we'll never have such insane JSON data. So there's absolutely ZERO reason to
+ * worry about memory-usage of the recursive array resolver in LazyJsonMapper.
+ * Especially since normal JSON maps usually have 1-2 levels of array-depth. Now
+ * we know that we'll easily handle 500 levels or more. So no need to worry!
+ *
+ * Therefore there's no need to implement any kind of non-recursive resolver for
+ * array processing in this library! Recursive function calls are by far the
+ * fastest way to traverse the whole data array.
+ *
+ * I'll keep this test-file just in case anyone ever complains about the
+ * decision to use recursive function calls for the multi-level array
+ * processing in LazyJsonMapper.

+// into "get" and "SomethingSomething".
+//
+// This kind of micro-optimization is kind of overkill. But so is
+// everything else about the LazyJsonMapper project! ;-) And I was
+// curious about the performance implications of each method!
+//
+// NOTE about algorithm speed:
+// In all of these test algorithms I do a "get" check LAST, to
+// force PHP to check less common prefixes first, to ensure
+// that it fairly represents normal usage (since the test-data
+// overrepresents its amount of "get" functions and would therefore
+// usually short-circuit each test very quickly). in a real
+// algorithm, get should be first, since it's the most common prefix.

+// preg_split algorithm:
+// very fast. splits on the first non-lowercase ("not a-z") character.
+// never any false positives! the prefix-split is truly perfect,
+// so "getgetgetSomething" would split as "getgetget" and "Something".
+// this is basically like the preg_match, except that we do the split
+// and THEN use regular string comparison to check if the prefix
+// is a valid one. this has the benefit of allowing us to add lots
+// of other prefixes over time, without slowing down a preg_match
+// regex even more (since that one has to slowly look for EACH possible
+// prefix string repeatedly and requires far more regex engine steps).
+//
+// NOTE: in both PHP5 and PHP7, the preg_split method is almost exactly
+// 5x slower than isset(), but we're talking about microsecond level!
+// a microsecond is a MILLIONTH of a second. so I'm going to choose
+// the preg_split method. it saves tons of RAM compared to caching
+// EVERY individual exact function name via isset(). the only really
+// heavy part is the FuncCase-to-property_name translation from the
+// SomethingSomething part of "getSomethingSomething". so THAT is the
+// only part we really need to cache. This initial prefix-splitting
+// is better handled live on every function call to save RAM.
+//
+// benchmarks:
+// PHP7:
+// preg_split per item: 0.5883 Microseconds (0.0000005883 seconds)
+// isset() per item: 0.1053 Microseconds (0.0000001053 seconds)
+// PHP5:
+// preg_split per item: 2.3158 Microseconds (0.0000023158 seconds)
+// isset() per item: 0.4752 Microseconds (0.000004752 seconds)
+//
+// so for a ~5x increase in operation time at a microsecond-level,
+// we get MUCH LOWER RAM USAGE by only having to cache the shared
+// "SomethingSomething" part, rather than "getSomethingSomething",
+// "setSomethingSomething", "isSomethingSomething", "hasSomethingSomething"
+// and "unsetSomethingSomething".
+//
+// for someone using tens of thousands of calls, the prefix splitting
+// will be impressively instant. just try this file with $iterations = 1!
+// in that case, all of the prefix-splittings for 10,000 function
+// calls run in a COMBINED total of ~3.4 milliseconds! for ALL of them!
+// even in PHP5 it's around ~11 milliseconds for 10,000 prefix-splits.
+//
+// even if someone has millions of magic function calls, they won't
+// notice this preg_split() processing in relation to all of their
+// other processing when they have that many calls! that's how fast
+// the splitting is. and it saves 5x RAM at the moment (and even more
+// if more function prefix variations are added later).

+ * multiple great methods for working with objects that have unpredictable keys!
+ *
+ * There are other methods too, such as if your class contains a blend of known
+ * (defined) keys and unpredictable keys, in which case you'd need to fetch via
+ * `asArray()` as in the `UnpredictableContainer` example, and then you'd simply
+ * filter out all known keys from your cache, to get _just_ the unpredictable
+ * keys. And if you need setters in that scenario, your setter functions would
+ * be a bit more complex since they would need to use `assignObjectData()` AND
+ * would have to provide BOTH the known data AND the unknown data. One way of
+ * doing that would be to use `_getProperty()` to merge in the CURRENT values of
+ * each core property into your NEW object-data array BEFORE you assign it. But
+ * I leave that extremely rare scenario as an excercise for you, dear reader!
+ *
+ * You should go out and adapt all of this code to fit your own needs! ;-)
+ *
+ * For example, if you don't need the unpredictable values to be converted
+ * to/from a specific object type, then simply skip the conversion code.
+ *
+ * If you don't need caching for performance, then skip the caching code.
+ *
+ * If you don't need setters/syncing, then skip all of that code.
+ *
+ * You may also want to disable the user-options `ALLOW_VIRTUAL_PROPERTIES` and
+ * `ALLOW_VIRTUAL_FUNCTIONS` on your unpredictable containers, so users cannot
+ * manipulate the unpredictable data via LazyJsonMapper's automatic functions!
+ * That's what we did for CoreUnpredictableContainer, to ensure that nobody can
+ * destroy its internal data by touching it directly. They can only manipulate
+ * the data via its safe, public `getData()` and `setData()` functions!
+ *
+ * And you may perhaps prefer to write a custom base-class which has a few other
+ * helper-functions for doing these kinds of data translations, caching and
+ * syncing, to make your own work easier (such as the CoreUnpredictableContainer
+ * example above). That way, your various sub-classes could just call your
+ * internal helper functions to do the required processing automatically! :-)

+ * The possibilities are endless! Have fun!

+/**
+ * Advanced, intelligent & automatic object-oriented JSON containers for PHP.
+ *
+ * Implements a highly efficient, automatic, object-oriented and lightweight
+ * (memory-wise) JSON data container. It provides intelligent data conversion
+ * and parsing, to give you a nice, reliable interface to your JSON data,
+ * without having to worry about doing any of the tedious parsing yourself.
+ *
+ * Features:
+ *
+ *  - Provides a completely object-oriented interface to all of your JSON data.
+ *
+ *  - Automatically maps complex, nested JSON data structures onto real PHP
+ *    objects, with total support for nested objects and multi-level arrays.
+ *
+ *  - Extremely optimized for very high performance and very low memory usage.
+ *    Much lower than other PHP JSON mappers that people have used in the past.
+ *
+ *    For example, normal PHP objects with manually defined `$properties`, which
+ *    is what's used by _other_ JSON mappers, will consume memory for every
+ *    property even if that property wasn't in the JSON data (is a `NULL`). Our
+ *    system on the other hand takes up ZERO bytes of RAM for any properties
+ *    that don't exist in the current object's JSON data!
+ *
+ *  - Automatically provides "direct virtual properties", which lets you
+ *    interact with the JSON data as if it were regular object properties,
+ *    such as `echo $item->some_value` and `$item->some_value = 'foo'`.
+ *
+ *    The virtual properties can be disabled via an option.
+ *
+ *  - Automatically provides object-oriented "virtual functions", which let you
+ *    interact with the data in a fully object-oriented way via functions such
+ *    as `$item->getSomeValue()` and `$item->setSomeValue('foo')`. We support a
+ *    large range of different functions for manipulating the JSON data, and you
+ *    can see a list of all available function names for all of your properties
+ *    by simply running `$item->printPropertyDescriptions()`.
+ *
+ *    The virtual functions can be disabled via an option.
+ *
+ *  - Includes the `LazyDoctor` tool, which _automatically_ documents all of
+ *    your `LazyJsonMapper`-based classes so that their virtual properties and
+ *    functions become _fully_ visible to your IDE and to various intelligent
+ *    code analysis tools. It also performs class diagnostics by compiling all
+ *    of your class property maps, which means that you can be 100% sure that
+ *    all of your maps are valid (compilable) if this tool runs successfully.
+ *
+ *  - We provide a complete, internal API which your subclasses can use to
+ *    interact with the data inside of the JSON container. This allows you to
+ *    easily override the automatic functions or create additional functions
+ *    for your objects. To override core functions, just define a function with
+ *    the exact same name on your object and make it do whatever you want to.
+ *
+ *    Here are some examples of function overriding:
+ *
+ *      ```php
+ *      public function getFoo()
+ *      {
+ *          // try to read property, and handle a special "current_time" value.
+ *          $value = $this->_getProperty('foo');
+ *          if ($value === 'current_time') { return time(); }
+ *          return $value;
+ *      }
+ *      public function setFoo(
+ *          $value)
+ *      {
+ *          // if they try to set value to "md5", use a special value instead.
+ *          if ($value === 'md5') { $value = md5(time()); }
+ *          return $this->_setProperty('foo', $value);
+ *      }
+ *      ```
+ *
+ *  - All mapping/data conversion is done "lazily", on a per-property basis.
+ *    When you access a property, that specific property is mapped/converted to
+ *    the proper type as defined by your class property map. No time or memory
+ *    is wasted converting properties that you never touch.
+ *
+ *  - Strong type-system. The class property map controls the exact types and
+ *    array depths. You can fully trust that the data you get/set will match
+ *    your specifications. Invalid data that mismatches the spec is impossible.
+ *
+ *  - Advanced settings system. Everything is easily configured via PHP class
+ *    constants, which means that your class-settings are stateless (there's no
+ *    need for any special "settings/mapper object" to keep track of settings),
+ *    and that all settings are immutable constants (which means that they are
+ *    reliable and can never mutate at runtime, so that you can fully trust that
+ *    classes will always behave as-defined in their code).
+ *
+ *    If you want to override multiple core settings identically for all of your
+ *    classes, then simply create a subclass of `LazyJsonMapper` and configure
+ *    all of your settings on that, and then derive all of your other classes
+ *    from your re-configured subclass!
+ *
+ *  - The world's most advanced mapper definition system. Your class property
+ *    maps are defined in an easy PHPdoc-style format, and support multilevel
+ *    arrays (such as `int[][]` for "an array of arrays of ints"), relative
+ *    types (so you can map properties to classes/objects that are relative to
+ *    the namespace of the class property map), parent inheritance (all of your
+ *    parent `extends`-hierarchy's maps will be included in your final property
+ *    map) and even multiple inheritance (you can literally "import" an infinite
+ *    number of other maps into your class, which don't come from your own
+ *    parent `extends`-hierarchy).
+ *
+ *  - Inheriting properties from parent classes or importing properties from
+ *    other classes is a zero-cost operation thanks to how efficient our
+ *    property map compiler is. So feel free to import everything you need.
+ *    You can even use this system to create importable classes that just hold
+ *    "collections" of shared properties, which you import into other classes.
+ *
+ *  - The class property maps are compiled a single time per-class at runtime,
+ *    the first time a class is used. The compilation process fully verifies
+ *    and compiles all property definitions, all parent maps, all inherited
+ *    maps, and all maps of all classes you link properties to.
+ *
+ *    If there are any compilation problems due to a badly written map anywhere
+ *    in your hierarchy, you will be shown the exact problem in great detail.
+ *
+ *    In case of success, the compiled and verified maps are all stored in an
+ *    incredibly memory-efficient format in a global cache which is shared by
+ *    your whole PHP runtime, which means that anything in your code or in any
+ *    other libraries which accesses the same classes will all share the cached
+ *    compilations of those classes, for maximum memory efficiency.
+ *
+ *  - You are also able to access JSON properties that haven't been defined in
+ *    the class property map. In that case, they are treated as undefined and
+ *    untyped (`mixed`) and there won't be any automatic type-conversion of such
+ *    properties, but it can still be handy in a pinch.
+ *
+ *  - There are lots of data export/output options for your object's JSON data,
+ *    to get it back out of the object again: As a multi-level array, as nested
+ *    stdClass objects, or as a JSON string representation of your object.
+ *
+ *  - We include a whole assortment of incredibly advanced debugging features:
+ *
+ *    You can run the constructor with `$requireAnalysis` to ensure that all
+ *    of your JSON data is successfully mapped according to your class property
+ *    map, and that you haven't missed defining any properties that exist in the
+ *    data. In case of any problems, the analysis message will give you a full
+ *    list of all problems encountered in your entire JSON data hierarchy.
+ *
+ *    For your class property maps themselves, you can run functions such as
+ *    `printPropertyDescriptions()` to see a complete list of all properties and
+ *    how they are defined. This helps debug your class inheritance and imports
+ *    to visually see what your final class map looks like, and it also helps
+ *    users see all available properties and all of their virtual functions.
+ *
+ *    And for the JSON data, you can use functions such as `printJson()` to get
+ *    a beautiful view of all internal JSON data, which is incredibly helpful
+ *    when you (or your users) need to figure out what's available inside the
+ *    current object instance's data storage.
+ *
+ *  - A fine-grained and logical exception-system which ensures that you can
+ *    always trust the behavior of your objects and can catch problems easily.
+ *    And everything we throw is _always_ based on `LazyJsonMapperException`,
+ *    which means that you can simply catch that single "root" exception
+ *    whenever you don't care about fine-grained differentiation.
+ *
+ *  - Clean and modular code ensures stability and future extensibility.
+ *
+ *  - Deep code documentation explains everything you could ever wonder about.
+ *
+ *  - Lastly, we implement super-efficient object serialization. Everything is
+ *    stored in a tightly packed format which minimizes data size when you need
+ *    to transfer your objects between runtimes.

+     *
+     * This constant can be overridden in your subclasses to toggle caching.
+     *
+     * The cache stores all of the current runtime's encountered magic/virtual
+     * function name translations, such as `SomeProperty` (via `getSomeProperty`
+     * and `setSomeProperty`, etc) and the fact that it refers to a JSON
+     * property that will be named either `some_property` (if snake style)
+     * or `someProperty` (if camel style).
+     *
+     * Entries are added to the cache one-by-one every time you call a function
+     * on an uncached property name for the first time. The next time you call a
+     * function which accesses the same property name, then there's no need to
+     * analyze the function name again (to figure out what JSON data property it
+     * refers to), since the translation is already cached. It is cached on a
+     * per-property name basis. So a SINGLE cached translation of `SomeProperty`
+     * will be shared by ALL function calls related to that property (such as
+     * all of the core functions; `hasSomeProperty`, `isSomeProperty`,
+     * `getSomeProperty`, `setSomeProperty`, and `unsetSomeProperty`).
+     *
+     * At the cost of a very tiny bit of RAM, this caching greatly speeds up
+     * magic function calls so that they only take about 16% as long as they
+     * would without the cache. However, they're still very fast even without a
+     * cache, and you may be accessing so many different properties that you'd
+     * prefer to avoid a cache for memory reasons (if you prefer lower memory
+     * needs over pure speed). The choice is yours.
+     *
+     * To calculate the memory needs of your own project's virtual function
+     * cache, you simply need to know that an average cache entry uses ~248.6
+     * bytes of RAM on PHP 7 and ~510.4 bytes on PHP 5. Note that the size per
+     * name translation is small enough to be measured in BYTES (NOT kilobytes)!
+     *
+     * Those averages were calculated from a huge sample-size of 10000 function
+     * names, and are very accurate for real-world JSON data.
+     *
+     * To calculate your own cache memory size, think about how many different
+     * JSON properties you'll need to access in your project. Most normal
+     * projects would probably only access at most 100 different property names
+     * (such as `getComments`, `setTime`, etc), since you most likely won't
+     * access every property in the JSON data. So only count the properties
+     * you'll access. And also remember that identical property names used
+     * across different classes, and all the different functions for accessing
+     * the same property, will still only require a SINGLE global cache entry
+     * per property name.
+     *
+     * The storage needs for 100 different property name translations would be
+     * as follows. As you can see, the cache is very memory-efficient:

+     * - PHP 7: 100x ~248.6 bytes = 24 860 bytes (~24.9 kilobytes).
+     * - PHP 5: 100x ~510.4 bytes = 51 040 bytes (~51.1 kilobytes).
+     *
+     * (If you're still using PHP 5, you should really consider upgrading to
+     * PHP 7 with its better memory efficiency and its much faster engine!)
+     *
+     * It is highly recommended to use caching, and it is enabled by default
+     * unless you override the constant in your class, as follows:
+     *
+     *   ```php
+     *   class MyUncachedLazyJsonMapper extends LazyJsonMapper
+     *   {
+     *       const USE_MAGIC_LOOKUP_CACHE = false;
+     *   }
+     *   ```
+     *
+     * With the above code, `MyUncachedLazyJsonMapper` (and anything extending
+     * from it) would run without using the magic function translation cache,
+     * which means that all magic "virtual function" calls on instances of that
+     * class would have to redo their property translations every time.
+     *
+     * @var bool
+     */
+    const USE_MAGIC_LOOKUP_CACHE = true;
+
+    /**
+     * Tells us how to map JSON properties to internal PHP types or objects.
+     *
+     * This constant can be overridden in your subclasses, to add custom JSON
+     * mapping definitions to your class. It is recommended to always do so.
+     *
+     * The value must be an array of key-value pairs, where the key is the name
+     * of a JSON property and the value is a string with the definition for that
+     * specific property in PHPdoc-style. We will then perform automatic, strict
+     * lazy-conversion of the value to the target type whenever you access that
+     * property. (However, be aware that we always allow `NULL` values in any
+     * property, and will never enforce/convert those to the target type.)
+     *
+     * The following built-in types are supported: `bool`, `int`, `float`,
+     * `string`. The JSON data will be type-converted to match that type.
+     *
+     * Note that if the type is set to `mixed` or an empty string `""` instead,
+     * then the property will allow any of the built-in types (`bool`, `int`,
+     * `float`, `string`, `NULL` (as always) and multi-level arrays of any of
+     * those types). There simply won't be any "forced" type-conversion to any
+     * specific basic type for that property since you haven't defined any
+     * strict type.
+     *
+     * Setting up untyped properties is still useful even if you don't know its
+     * type, since defining the property in the class map ensures that you can
+     * always get/set/access/use that property even if it's unavailable in the
+     * current object instance's internal JSON data.
+     *
+     * You can also map values to objects. In the case of objects (classes), the
+     * classes MUST inherit from `LazyJsonMapper` so they support all necessary
+     * mapping features. To assign a class to a property, you can either write a
+     * FULL (global) class path starting with a leading backslash `\`, such as
+     * `\Foo\Bar\Baz`. Alternatively, you can use a RELATIVE path related to the
+     * namespace of the CURRENT MAP'S class, such as `Bar\Baz` (if your current
+     * class is `\Foo\Whatever`, then it'd be interpreted as `\Foo\Bar\Baz`).
+     * Anything that DOESN'T start with a leading backslash is interpreted as a
+     * relative class path! Just be aware that your class `use`-statements are
+     * completely ignored since PHP has no mechanism to let us detect those.
+     *
+     * It's also possible to map properties to the core `LazyJsonMapper` object
+     * if you simply want an object-oriented container for its data without
+     * writing a custom class. You can do that by defining the property type as
+     * either `\LazyJsonMapper\LazyJsonMapper`, or as `LazyJsonMapper` (which is
+     * a special shortcut that ALWAYS resolves to the core class). But it's
+     * always best to write a proper class, so that its properties are reliable.
+     *
+     * Lastly, you can map "arrays of TYPE" as well. Simply add one or more `[]`
+     * brackets to the end of the type. For example, `int[]` means "array of
+     * ints", and `\Foo[][][]` means "array of arrays of arrays of `\Foo`
+     * objects". It may be easier to understand those mentally if you read them
+     * backwards and say the words "array of" every time you see a `[]` bracket.
+     * (Note: You can also use the array notation with `mixed[][]`, which would
+     * then strictly define that the value MUST be mixed data at an exact depth
+     * of 2 arrays, and that no further arrays are allowed deeper than that.)
+     *
+     * The assigned types and array-depths are STRICTLY validated. That's an
+     * integral part of the `LazyJsonMapper` container, since it guarantees your
+     * class property map interface will be strictly followed, and that you can
+     * fully TRUST the data you're interacting with. If your map says that the
+     * array data is at depth 8 and consists of `YourObject` objects, then we'll
+     * make sure the data is indeed at depth 8 and their value type is correct!
+     *
+     * That goes for arrays too. If you define an `int[]` array of ints, then
+     * we'll ensure that the array has sequential numeric keys starting at 0 and
+     * going up without any gaps, exactly as a JSON array is supposed to be. And
+     * if you define an object `YourObject`, then we'll ensure that the input
+     * JSON data consists of an array with associative keys there (which is used
+     * as the object properties), exactly as a JSON object is supposed to be.
+     *
+     * In other words, you can TOTALLY trust your data if you've assigned types!
+     *
+     * Example property map:
+     *
+     * ```php
+     * const JSON_PROPERTY_MAP = [
+     *     'some_string'              => 'string',
+     *     'an_object'                => '\YourProject\YourObject',
+     *     'array_of_numbers'         => 'int[]',
+     *     'array_of_objects'         => 'RelativeObject[]',
+     *     'untyped_value'            => '', // shorthand for 'mixed' below:
+     *     'another_untyped_value'    => 'mixed', // allows multilevel arrays
+     *     'deep_arr_of_arrs_of_int'  => 'int[][]',
+     *     'array_of_mixed'           => 'mixed[]', // enforces 1-level depth
+     *     'array_of_generic_objects' => 'LazyJsonMapper[]',
+     * ];
+     * ```
+     *
+     * Also note that we automatically inherit all of the class maps from all
+     * parents higher up in your object-inheritance chain. In case of a property
+     * name clash, the deepest child class definition of it takes precedence.
+     *
+     * It is also worth knowing that we support a special "multiple inheritance"
+     * instruction which allows you to "import the map" from one or more other
+     * classes. The imported maps will be merged onto your current class, as if
+     * the entire hierarchy of properties from the target class (including the
+     * target class' inherited parents and own imports) had been "pasted inside"
+     * your class' property map at that point. And you don't have to worry
+     * about carefully writing your inheritance relationships, because we have
+     * full protection against circular references (when two objects try to
+     * import each other) and will safely detect that issue at runtime whenever
+     * we try to compile the maps of either of those bad classes with their
+     * badly written imports.
+     *
+     * The instruction for importing other maps is very simple: You just have to
+     * add an unkeyed array element with a reference to the other class. The
+     * other class must simply refer to the relative or full path of the class,
+     * followed by `::class`.
+     *
+     * Example of importing one or more maps from other classes:
+     *
+     * ```php
+     * const JSON_PROPERTY_MAP = [
+     *     'my_own_prop'                     => 'string',
+     *     OtherClass::class,                // relative class path
+     *     'redefined_prop'                  => float,
+     *     \OtherNamespace\SomeClass::class, // full class path
+     * ];
+     * ```
+     *
+     * The imports are resolved in the exact order they're listed in the array.
+     * Any property name clashes will always choose the version from the latest
+     * statement in the list. So in this example, our class would first inherit
+     * all of its own parent (`extends`) class maps. Then it would add/overwrite
+     * `my_own_prop`. Then it imports everything from `OtherClass` (and its
+     * parents/imports). Then it adds/overwrites `redefined_prop` (useful if you
+     * want to re-define some property that was inherited from the other class).
+     * And lastly, it imports everything from `\OtherNamespace\SomeClass` (and
+     * its parents/imports). As long as there are no circular references,
+     * everything will compile successfully and you will end up with a very
+     * advanced final map! And any other class which later inherits from
+     * (extends) or imports YOUR class will inherit the same advanced map from
+     * you! This is REAL "multiple inheritance"! ;-)
+     *
+     * Also note that "relative class path" properties are properly inherited as
+     * pointing to whatever was relative to the original inherited/imported
+     * class where the property was defined. You don't have to worry about that.
+     *
+     * The only thing you should keep in mind is that we ONLY import the maps.
+     * We do NOT import any functions from the imported classes (such as its
+     * overridden functions), since there's no way for us to affect how PHP
+     * resolves function calls to "copy" functions from one class to another. If
+     * you need their functions, then you should simply `extends` from the class
+     * to get true PHP inheritance instead of only importing its map. Or you
+     * could just simply put your functions in PHP Traits and Interfaces so
+     * that they can be re-used by various classes without needing inheritance!
+     *
+     * Lastly, here's an important general note about imports and inheritance:
+     * You DON'T have to worry about "increased memory usage" when importing or
+     * inheriting tons of other classes. The runtime "map compiler" is extremely
+     * efficient and re-uses the already-compiled properties inherited from its
+     * parents/imports, meaning that property inheritance is a ZERO-COST memory
+     * operation! In fact, re-definitions are also zero-cost as long as your
+     * class re-defines a property to the exact same type that it had already
+     * inherited/imported. Such as `Base: foo:string, Child: foo:string`. In
+     * that case, we detect that the definitions are identical and just re-use
+     * the compiled property from `Base` instead. It's only when a class adds
+     * NEW/MODIFIED properties that memory usage increases a little bit! In
+     * other words, inheritance/imports are a very good thing, and are always a
+     * better idea than manually writing similar lists of properties in various
+     * unrelated (not extending each other) classes. In fact, if you have a
+     * situation where many classes need similar properties, then it's a GREAT
+     * idea to create special re-usable "property collection" classes and then
+     * simply importing THOSE into ALL of the different classes that need those
+     * sets of properties! You can even use that technique to get around PHP's
+     * `use`-statement limitations (simply place a "property collection" class
+     * container in the namespace that had all of your `use`-classes, and define
+     * its properties via easy, relative paths there, and then simply make your
+     * other classes import THAT container to get all of its properties).
+     *
+     * As you can see, the mapping and inheritance system is extremely powerful!
+     *
+     * Note that the property maps are analyzed and compiled at runtime, the
+     * first time we encounter each class. After compilation, the compiled maps
+     * become immutable (cannot be modified). So there's no point trying to
+     * modify this variable at runtime. That's also partially the reason why
+     * this is defined through a constant, since they prevent you from modifying
+     * the array at runtime and you believing that it would update your map. The
+     * compiled maps are immutable at runtime for performance & safety reasons!
+     *
+     * Have fun!

+     * This is where you can perform your custom subclass initialization, since
+     * you are unable to override the main constructor.
+     *
+     * We automatically run this function at the end of the normal constructor,
+     * as well as every time that you manually use `assignObjectData()` to
+     * replace the object's data. (When new data is assigned, you should treat
+     * yourself as a new object, which is why `_init()` will run again.)
+     *
+     * `WARNING:` Please RESIST the urge to touch ANY of the internal JSON data
+     * during this initialization. All data will always be automatically
+     * validated during actual retrieval and setting, so you can always trust
+     * that the final types WILL match your class property map definitions.
+     *
+     * Remember that any extra work you do in `_init()` will run EVERY time an
+     * instance of your object is created, even when those objects live within a
+     * main object. So if your function is heavy, it will slow down operation of
+     * the class; and your parsing of the properties would be counter-productive
+     * against the goal of "lazy parsing" of JSON data on a when-accessed basis!
+     *
+     * Instead, it's preferable to just override specific property getter and
+     * setter functions, to make your class return different default values if a
+     * certain internal data field is missing an expected value. But in general,
+     * your ultimate USER CODE should be responsible for most of THAT checking,
+     * by simply looking for `NULL` (denoting a missing value in the JSON data
+     * container), and then deciding what to do with that in your final project.
+     *
+     * Lastly, there are a few rules that MUST be followed by your `_init()`:
+     *
+     *  1. As explained above, but worth repeating again: Your `LazyJsonMapper`
+     *  classes are supposed to be LIGHT-weight "JSON data containers". So
+     *  please DO NOT treat this as a "standard class constructor". The more
+     *  work you do in `_init()`, the slower your object creation is. And since
+     *  your object is a JSON container which is automatically created from
+     *  data, you can expect LOTS of instances of your class to be created
+     *  during normal runtime! That's also why your `_init()` function does not
+     *  get any parameters! That is to discourage misuse as a normal class.
+     *
+     *  Also remember that you may not even need `_init()`, since you can simply
+     *  give your properties default values instead of using `_init()`, such as
+     *  by writing `public $myproperty = true;`. All instances of that object
+     *  would then start with that value set to `TRUE` by default.
+     *
+     *  2. You can ONLY throw `LazyUserException`. All other exceptions will be
+     *  blocked and turned into a generic `LazyUserException`. This is done to
+     *  ensure that your custom init function cannot break the contract that the
+     *  `LazyJsonMapper` constructor guarantees in its listed exceptions.
+     *
+     *  (That's also the reason why all built-in functions except `_init()` are
+     *  marked `final`: So that subclasses cannot break the `LazyJsonMapper`
+     *  API/interface contract. If something IS a `LazyJsonMapper`, it MUST
+     *  behave as a `LazyJsonMapper`, and the `final` functions guarantee that!)
+     *
+     *  3. If your class extends from `LazyJsonMapper`, then there's no need to
+     *  call `parent::_init()` (since our core `_init()` does nothing). But if
+     *  you extend from ANY OTHER CLASS, you MUST call your parent's init BEFORE
+     *  doing any work, just to guarantee that your WHOLE parent-class hierarchy
+     *  is fully initialized first.
+     *
+     *  4. Understand and accept the fact that your personal class properties
+     *  will NOT be serialized if you serialize an object. Only the JSON data
+     *  array will be kept. The `_init()` function will be called again when you
+     *  unserialize the object data, as if your object had just been created for
+     *  the first time. This is done to save space and to discourage misuse
+     *  of your `LazyJsonMapper` containers.
+     *
+     *  Remember that your classes are supposed to be lightweight JSON data
+     *  containers, which give you a strongly typed, automatic, object-oriented
+     *  interface to your data. Classes "with advanced constructors and tons of
+     *  properties" are NOT suitable as JSON containers and belong ELSEWHERE in
+     *  the rest of your project!
+     *
+     * @throws LazyUserException If there is any fatal error which prevents
+     *                           initialization. This stops object construction
+     *                           if this is the initial construction. However,
+     *                           it doesn't affect data-assignment if you throw
+     *                           during a later `assignObjectData()` call.

+     * It is recommended that you save the result if you intend to re-use it
+     * multiple times, since each call to this function will need to perform
+     * copying and data conversion from our internal object representation.
+     *
+     * Note that the conversion process will recursively validate and convert
+     * all properties in the entire internal data hierarchy. You can trust that
+     * the returned result will be perfectly accurate and follow your class map
+     * property type-rules. This does however mean that the data may not be the
+     * same as the input array you gave to `__construct()`. For example, if your
+     * input contained an array `["1", "2"]` and your type definition map says
+     * that you want `int` for that property, then you'd get `[1, 2]` as output.
+     *
+     * The conversion is always done on a temporary COPY of the internal data,
+     * which means that you're welcome to run this function as much as you want
+     * without causing your object to grow from resolving all its sub-objects.

+     * do ANYTHING with it, without risk of affecting any of OUR internal data.

+     * `WARNING:` If you intend to use the result to `json_encode()` a new JSON
+     * object then please DON'T do that. Look at `asJson()` instead, which gives
+     * you full control over all JSON output parameters and properly handles the
+     * conversion in all scenarios, without you needing to do any manual work.

+     * This lets you analyze the object data & map to look for the following:
+     *
+     *  1. Undefined JSON properties that need to be defined in your classes
+     *  so that their existence becomes permanent and therefore safer to use
+     *  (since defined properties are always retrievable even if they don't
+     *  exist in the current object instance's data). And actually defining
+     *  the properties is also the ONLY way that you can enforce a specific
+     *  data-type, since undefined properties default to untyped (`mixed`).
+     *
+     *  2. Bad class map definitions that don't match the actual JSON data.
+     *  It does this by checking all of the encountered classes within the JSON
+     *  data to ensure that they construct successfully (which they ALWAYS
+     *  will, unless the user has overridden `_init()` and throws from it), as
+     *  well as verifying that all basic PHP type coercions work, and that the
+     *  data is formatted as-described in the definition (such as having the
+     *  correct array-depth, or data defined as objects actually being objects).
+     *
+     * The scan is performed by looking at EVERY item in the object's internal
+     * JSON data array, and checking for a corresponding class map definition
+     * (if nothing exists, it's treated as "missing from the class map"), and
+     * then attempting conversion to its specified type (if that fails, it's
+     * treated as "bad class map definition"). All undefined values (which lack
+     * any class map definition) are ALSO validated as if they were `mixed`,
+     * to ensure that NOTHING can contain illegal values.
+     *
+     * If a recursive scan is requested, then all sub-objects (`LazyJsonMapper`
+     * data containers) will ALSO recursively perform the same analysis on their
+     * own internal data, so that the whole JSON data tree is recursively
+     * verified. Their analysis results will be merged with our return value.
+     *
+     * Note that calling this function will cause the WHOLE object tree to be
+     * constructed and ALL of its mapped properties to be converted/parsed to
+     * verify the class map, which takes some time and permanently increases the
+     * object's memory usage (since conversion causes any internal sub-objects
+     * to be stored as actual objects instead of merely as plain sub-arrays)!
+     *
+     * Therefore, you should ONLY use this function when necessary: When you
+     * need advanced and powerful debugging of your class maps!

+     * the code above fails if no internal data for that property exists yet. In
+     * that case, the code above will write to a temporary `NULL` variable which
+     * is not linked at all to the object. Instead, you MUST ALWAYS use
+     * `$createMissingValue = true` if you want TRUSTABLE data references.
+     *
+     * Method 2 (the CORRECT way of writing it):
+     *
+     *  ```php
+     *  $val = &$this->_getProperty('foo', true);
+     *  $val = 'bar';
+     *  ```
+     *
+     * That FIXED code will create the property and put `NULL` in it if it's
+     * missing from the internal data, and then returns the reference to the
+     * created internal data entry. It's the ONLY way to ensure REAL references.
+     *
+     * Note that there is ZERO PERFORMANCE BENEFIT of assigning our return-value
+     * by reference. ONLY use references if you have an ADVANCED reason for it!
+     * Internally, PHP treats both assignment types identically until the moment
+     * you try to write to/modify the contents of the variable. So if you are
+     * only reading, which is most of the time, then there's no reason to use a
+     * reference. And never forget that modifying via direct reference lets you
+     * write invalid data (which won't be detected until a `_getProperty()`
+     * call attempts to read that bad data again), as mentioned earlier.
+     *
+     * There is one final warning: If YOU have a "return-by-reference" function,
+     * then you will AUTOMATICALLY return a direct link to the inner data if you
+     * use us directly in your return statement. Here's an example of that:
+     *
+     *  ```php
+     *  public function &myFunction() { // <-- Note the "&" return-by-ref here!
+     *      // returns reference to real internal data OR temp var (badly coded)
+     *      return $this->_getProperty('foo'); // <-- VERY DANGEROUS BUG!
+     *
+     *      // returns reference to real internal data (correctly coded)
+     *      return $this->_getProperty('foo', true); // <-- CORRECT!
+     *
+     *      // you can also intentionally break the link to the internal data,
+     *      // by putting it in a copy-on-write variable and returning THAT:
+     *      $copyOnWrite = $this->_getProperty('foo'); // copy-on-write (no ref)
+     *      return $copyOnWrite; // ref to $copyOnWrite but not to real internal
+     *  }
+     *  ```
+     *
+     * @param string $propName           The property name.
+     * @param bool   $createMissingValue If `TRUE` then we will create missing
+     *                                   internal object data entries (for
+     *                                   class-defined properties) and store a
+     *                                   `NULL` in them. This will "pollute" the
+     *                                   internal data with default `NULL`s for
+     *                                   every missing property that you attempt
+     *                                   to retrieve, but it's totally NECESSARY
+     *                                   if you intend to use the return-value
+     *                                   by-reference, since we MUST store the
+     *                                   value internally when you want the
+     *                                   returned reference to link to our
+     *                                   actual object's internal data storage!

+     * `WARNING:` Note that the `__get()` "virtual property" handling creates
+     * `NULL` values in any missing (but valid in class-map) properties that you
+     * try to access! That is NECESSARY because PHP EXPECTS the `__get()` return
+     * value to be a REFERENCE to real internal data, so we MUST create a value
+     * if no value exists, so that we can link PHP to a true reference to the
+     * internal data. Obviously we can't link to something that doesn't exist,
+     * which is why we MUST create `NULL` values. Unfortunately that means that
+     * "virtual property access" will lead to increased memory usage and worse
+     * JSON output (due to all the added values) if you want to export the
+     * internal data as JSON later.
+     *
+     * The recommended access method, `$obj->getFoo()` ("virtual functions")
+     * doesn't have that problem. It ONLY happens when you decide to use
+     * `$obj->foo` for "direct virtual property" access.
+     *
+     * There are several other quirks with "direct virtual properties", due to
+     * how PHP works. If you don't write your code carefully, you may cause
+     * serious issues with performance or unexpected results.
+     *
+     * All of the important quirks are as follows:
+     *
+     *  1. The aforementioned necessary `NULL` value insertion increases memory
+     *  usage and may lead to unexpected problems if you convert back to JSON,
+     *  such as if the server does not expect those values to exist with `NULL`.
+     *
+     *  2. Anytime you use the array `[]` access operator on the outer property
+     *  name, PHP will trigger a `__get()` call, which of course does its whole
+     *  data-validation again. The following would therefore be EXTREMELY SLOW,
+     *  and possibly even DANGEROUS (since you're manipulating the array while
+     *  looping over its keys while constantly triggering `__get()` re-parsing):
+     *
+     *    ```php
+     *    foreach ($obj->something as $k => $v) {
+     *        // Every assignment here will do __get('something') which parses
+     *        // the array over and over again before each element is modified:
+     *        $obj->something[$k] = 'foo';
+     *    }
+     *    ```
+     *
+     *  The proper way to solve THAT is to either save a reference to
+     *  `$obj->something` as follows:
+     *
+     *    ```php
+     *    $ref = &$obj->something; // Calls __get('something') a single time.
+     *    foreach ($ref as $k => $v) {
+     *        $ref[$k] = 'foo'; // Changes array directly via stored reference.
+     *    }
+     *    ```
+     *
+     *  Or to loop through the input values as follows:
+     *
+     *    ```php
+     *    foreach ($obj->something as &$v) { // Note the "&" symbol.
+     *        $v = 'foo'; // Changes array value directly via reference.
+     *    }
+     *    ```
+     *
+     *  3. Anytime you use a reference, there will be NO DATA VALIDATION of the
+     *  new value you are inputting. It will not be checked again UNTIL the next
+     *  internal `_getProperty()` call for that property (ie. by the next
+     *  `__get()`) so you may therefore unintentionally insert bad data that
+     *  doesn't match the class definition map:
+     *
+     *    ```php
+     *    // Saving a reference to internal data and then changing that variable
+     *    // will directly edit the value without letting us validate it:
+     *
+     *    $ref = &$obj->some_string; // Make "$ref" into a reference to data.
+     *    $ref = new InvalidObject(); // Writes a bad value directly to memory.
+     *    var_dump($obj->some_string); // Throws error because of bad data.
+     *
+     *    // The same is true about array access. In this case, PHP does
+     *    // __get('some_int_array') and finds an array, and then it directly
+     *    // manipulates that array's memory without letting us validate it:
+     *
+     *    $obj->some_int_array[] = new InvalidObject();
+     *    $obj->some_int_array[15] = new InvalidObject();
+     *    var_dump($obj->some_int_array); // Throws error because of bad data.
+     *    ```
+     *
+     *  4. You can always trust that `__set()` assignments WILL be validated.
+     *  But a `__set()` ONLY happens when you assign with the equals operator
+     *  (`=`) to a pure property name WITHOUT any array access (`[]`) operators.
+     *
+     *    ```php
+     *    $obj->some_property = '123'; // Calls __set() and validates new value.
+     *    $obj->an_array[] = '123' // Calls __get() and won't validate changes.
+     *    ```
+     *
+     * These quirks of "virtual direct property access" are quite easy to deal
+     * with when you know about them, since almost all of them are about array
+     * access, and the rest are about intentional misuse by binding directly to
+     * references. Just avoid making those mistakes.
+     *
+     * However, in general, you should REALLY be using the "virtual function"
+     * access method instead, which allows you to do great things such as
+     * overriding certain class property-functions (ie `getSomething()`) with
+     * your own custom behaviors, so that you can do extra validation, get/set
+     * value transformations, and other fantastic things!
+     *
+     * It is possible (and recommended) to disable virtual properties via the
+     * `ALLOW_VIRTUAL_PROPERTIES` class constant. The feature is only enabled by
+     * default because it helps people easily migrate from legacy projects.

+     * consumed by the compiled maps from each class.
+     *
+     * All currently existing object instances will continue to work, since they
+     * retain their own personal links to their own compiled property maps.
+     * Therefore, the memory you free by calling this function may not be the
+     * full amount (until ALL of the object instances of all classes are freed).
+     * PHP will only be able to free their unused parent classes, and their
+     * unused subclasses, and any other unused classes in general. But PHP will
+     * retain memory for the SPECIFIC, per-class maps for all living objects.
+     *
+     * Calling this function is totally harmless, since all future class
+     * instance constructors will simply re-compile their whole map hierarchies
+     * again from scratch, and all class maps will be re-built IDENTICALLY the
+     * next time since all of their map definitions themselves are immutable
+     * class constants and can NEVER be modified at runtime (not even via PHP
+     * 7.1's advanced `ReflectionClassConstant` class).
+     *
+     * However, because of the fact that all existing object instances retain
+     * private links to their own maps from the previous compilation, it means
+     * that you may actually end up using MORE memory after clearing the global
+     * cache, IF you still have a LOT of different living object instances AND
+     * also begin to create new instances of various classes again (and thus
+     * begin re-compiling new, global instances of each of their "cleared" class
+     * property maps).

+     * legally generate such function names. Instead, we'll encode the operators
+     * with a sequence that will never appear in our normal algorithm's output.
+     *
+     * For example, if the user has a property named `en-US`, our special
+     * operator translation will give it a function name of `getEn_x2D_US()`
+     * to safely encode the arithmetic minus symbol.
+     *
+     * This encoding scheme was deliberately chosen thanks to the fact that it
+     * will never conflict with anything else that's legitimately generated by
+     * our algorithm. Because if the user has a property that's _actually_ named
+     * `en_x2D_US`, then that one would be encoded as `getEnX2D_US()` (by the
+     * main `PropertyTranslation` algorithm), which is obviously not the same
+     * thing and will never confuse our parser in decoding later. And if they
+     * sent us `en__x2D_US`, it would be encoded as `getEn_X2D_US()`, which is
+     * yet again different (the `X` is uppercase in that situation too).
+     *
+     * Therefore, our special encoding of `_x[HEX]_` will never be generated by
+     * any legitimate user property names, even if those names do contain that
+     * sequence on-disk. They'll all be encoded to something else. The only
+     * thing that can put a lowercase `x` in this particular arrangement is our
+     * own operator symbol translator here.
+     *
+     * As for why we need that long sequence instead of something shorter, it's
+     * unfortunately the only way that we can guarantee uniqueness. It relies on
+     * the principle that `_x` in the user's own properties would ALWAYS be
+     * encoded as `X`. Most programmers are familiar with hex codes and will
+     * recognize the sequences we've chosen: `getEn_x2D_US()`, where `x` stands
+     * for "hex", and `2D` is the hex character value for the minus symbol.
+     *
+     * This particular encoding also allows us to easily encode future illegal
+     * characters of any length (even multiple bytes such as `_xFFFF_` if ever
+     * necessary) without needing to change the encoding scheme again.

+     *
+     * That extra protection does however also mean that your runtime's initial

+        // would cause a circular reference if we'd tried to compile those
+        // property-classes instantly as-they're encountered). We must therefore
+        // defer property-class compilation until ALL core classes in the
+        // current inheritance/import chain are resolved. THEN it's safe to
+        // begin compiling any other encountered classes from the properties...
+        //
+        // The solution is "simple": Build a list of the class-paths of all
+        // encountered UNCOMPILED property classes within our own map tree and
+        // within any imports (which are done via recursive compile-calls). To
+        // handle imports, we simply ensure that our compile-function (this one)
+        // lets the parent retrieve our list of "encountered uncompiled classes
+        // from properties" so that we'll let it bubble up all the way to the
+        // root class/call that began the whole compile-chain. And then just let
+        // that root-level call resolve ALL uncompiled properties from the
+        // ENTIRE tree by simply compiling the list of property-classes one by
+        // one if they're still missing. That way, we'll get full protection
+        // against uncompilable class-properties ANYWHERE in our tree, and we'll
+        // do it at a totally safe time (at the end of the main compilation call
+        // that kicked everything off)!
+        //
+        // NOTE: As an optimization, to avoid constant array-writes and the
+        // creation of huge and rapidly growing "encountered classes" arrays, we
+        // will attempt to ONLY track the encountered classes that are MISSING
+        // from the cache (not yet compiled). And this list will ALSO be checked
+        // one more time at the end, to truly clear everything that's already
+        // done. That's intended to make the list as light-weight as possible
+        // so that our parent-compiler doesn't have to do heavy lifting.
+        //
+        // NOTE: The fact is that most classes that properties point to will

+### Notes:
+We will close your feature request, sometimes without answering, if any of the following are met:

+### Description
+Please include a well-worded description of your feature request. Please make sure to include where on the app this feature is acceptable so we can reproduce it. Additionally, it would make our lives easier if you are able to post the endpoint, its associated parameters, and response.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team. All complaints will be reviewed and investigated and will result in a response that is deemed necessary and appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.

+## What should I know before I get started?
+
+### Code of Conduct
+
+This project adheres to the Contributor Covenant [code of conduct](CODE_OF_CONDUCT.md).
+By participating, you are expected to uphold this code.
+Please report any unacceptable behavior.
+
+## Basic rules
+
+Important! Your contributions must follow all of these rules for a consistent and bug-free project.
+
+This is a document which, among other things, describes PSR-4 class autoloading, clean commits, how to handle/document exceptions, how to structure function arguments, naming clear variables, always adding/updating PHPdoc blocks in all affected functions, and how to verify that your changes don't _break everything_ when performing big changes to existing functions or adding brand new functions and classes.
+
+
+### Git Setup
+
+If you are using a Linux/Mac/Unix system, you **MUST** install our git-hook in your local repository. It will help prevent you from accidentally committing badly formatted code. Please run the following command in the project's root folder (the folder which has files like `README.md` etc), to install the hook in your repository:
+
+```
+ln -fs "../../.pre-commit.hook" .git/hooks/pre-commit
+```
+
+
+### Codestyle Command
+
+Before committing any work, you **MUST** always run the codestyle fixer command in the root folder of the repository:
+
+```
+composer codestyle
+```
+
+That command will automatically fix all codestyle issues as well as generate various documentation, such as the class docs for all of the Responses and Model items.
+
+
+### Available Tasks
+
+Please visit our [Project Task Tracker](https://github.com/mgp25/Instagram-API/projects), where contributors can look at the list of available work. High-quality code contributions are greatly appreciated.
+
+
+### Commits
+
+- You **MUST** try to **separate** work into smaller commits. So if you `"changed Utils.php to fix getSeconds and changed Request.php to fix Request()"`, then make **TWO SEPARATE COMMITS**, so that we can easily find your changes in the project history, and can easily revert any individual broken changes without losing tons of other code too! So remember: 1 commit per task. :smile:
+
+- Use the detailed description field of your commit, to document why you did certain changes if it's not an obvious change (such as a typo fix). Your description gets added to the history of the project so that we can know what you were thinking, if we need to check the change again later.
+
+- **Name** your single-file commits `"AffectedClassName: Change description"` and keep the total length of the summary line at 50 characters or less in total (the Git/GitHub standard).
+
+- If your change NEEDS to affect multiple files, then it is SOMETIMES okay to leave out the classname part from the summary, but in that case you _must_ write a very clear and descriptive summary to explain it. _But_ usually you _should_ still include the classname even for multi-file edits. For example, renaming a function in Utils and having to change the name of it in other files is still a `"Utils: Renamed bleh() to bloop()"` commit.
+
+Examples of BAD commit summaries:
+
+```
+Edit something
+Fix this
+Utils+request changes
+```
+
+Examples of GOOD commit summaries:
+
+```
+Utils: Fix formatting of getSeconds
+Request: Send cropping information
+Changed all number_format() to round() everywhere
+Response: Parse timestamps as floats
+```
+
+
+### Modifying anything in the existing code
+
+- If you want to change a public API function's parameters (particularly in `src/Instagram.php`), think EXTREMELY hard about NOT doing it. And if you absolutely MUST do it (such as adding an important new parameter), then you MUST add it in a BACKWARDS-COMPATIBLE WAY, by adding it as the LAST parameter of the argument list AND providing a sensible DEFAULT VALUE for it so that people's CURRENT projects based on this library continue working and DON'T BREAK due to your function definition changes!
+
+- Do NOT look at your changes in isolation. Look at the BIG PICTURE of what your change now does to the REST of the codebase.
+
+- For example, if you change the returned variable type from a function (such as from an `"int"` to a `"string"`), then you MUST update the function's PHPdoc block to document the new return value (with `@return string`), and you MUST also slowly and carefully check ALL OTHER CODE that relied on the OLD behavior of that function. There's a command-line tool called "grep" (or an even better one especially made for programmers, called ["ag" aka "the silver searcher"](https://github.com/ggreer/the_silver_searcher)) to search for text in files. USE IT to check ALL other code locations that called your modified function, and make sure that you didn't break ANY of them AT ALL!
+
+- In fact, ANY TIME that you change a function's ARGUMENTS, RETURN VALUE or THROWN EXCEPTIONS (new/deleted ones), then you MUST update the function's PHPdoc block to match the new truth. And you MUST check ALL other functions that CALL your function, and update those too. For example let's say they DON'T handle a new exception you're now throwing, in which case you MUST now update THEIR `@throws` documentation to document the fact that THEY now let yet another exception bubble up. And then you MUST search for the functions that called THOSE updated functions and update THEIR documentation TOO, all the way until you've reached the top and have FULLY documented what exceptions are being thrown in the whole chain of function calls.
+
+- You MUST ALWAYS update the PHPdoc blocks EVERYWHERE that's affected by your changes (whenever you've changed a functions ARGUMENTS or RETURN type or what it THROWS (any new/deleted exceptions)), because imagine if we NEVER update the blocks EVERYWHERE that's affected by your change. We would then have something like `/** @param $a, $b, $c */ function foo ($x)` and sudden, critical exceptions that aren't getting handled and thus KILL the program.
+
+Here's a checklist for what you MUST do to ENSURE totally correct documentation EVERY TIME that you make a CHANGE to a function's ARGUMENTS or RETURN TYPE or EXCEPTIONS of an existing function, OR when you introduce a NEW function whose use is being added to any existing functions.
+
+1. You MUST ALWAYS use grep/ag. Find EVERY other code location that uses your new/modified function.
+
+2. Check: Did your changes just BREAK EVERYTHING somewhere else, which now has to be updated to match? Almost GUARANTEED the answer is YES, and you MUST update the other locations that expected the old function behavior/return type/parameters/exceptions.
+
+3. Check: Do you need to also UPDATE the PHPdoc for those OTHER functions too? OFTEN the answer is YES. For example, if you've changed the exceptions that a deep, internal function throws, then you MUST either catch it in all higher functions and do something with it, OR let it pass through them upwards. And if you do let it pass through and bubble up then you MUST ALSO update the PHPdoc for THAT higher function to say `"@throws TheNewException"` (or delete something in case you changed a subfunction to no longer throw).
+
+4. If your updates to the affected higher-level functions in steps 2/3 means that THOSE other functions now ALSO behave differently (meaning THEY have new return values/exceptions/parameters), then you MUST also do ANOTHER grep/ag to check for anything that uses THOSE functions, and update all of those code locations TOO. And continue that way up the entire chain of functions that call each other, until you reach the top of the project, so that the entire chain of function calls is caught/documented properly. Otherwise, those unexpected (undocumented) exceptions will terminate PHP, so this is very important!
+
+
+
+## Styleguides
+
+### Namespaces
+
+- Organize all classes into logical namespaces.
+
+- We follow the PSR-4 Autoloading standard, which means that you MUST only have ONE class per source code `.php` file. And the namespace AND classname MUST match BOTH its disk path AND its `.php` filename. In our project, the `src/` folder is the `InstagramAPI` namespace, and everything under that is for its subnamespaces (folders) and our classes (PHP files).
+
+Example of a proper class in our top-level namespace:
+
+```php
+src/Something.php:
+<?php
+
+namespace InstagramAPI;
+
+class Something
+{
+    ....
+}
+```
+
+Example of a proper class in a sub-namespace:
+
+```php
+src/Wonderful/Things/Something.php:
+<?php
+
+namespace InstagramAPI\Wonderful\Things;
+
+class Something
+{
+    ....
+}
+```
+
+### Functions and Variables
+
+- You MUST split all function declaration/definition arguments onto separate lines, but only IF the function takes arguments. This is done for clarity, and to avoid unintentional bugs by contributors. It ensures that any changes to function arguments will be diffed as a single-line change. It's more readable. And it's the style _we_ use.
+
+Example of a function that takes no arguments:
+
+```php
+public function doSomething()
+{
+    ...
+}
+```
+
+Example of a function that takes one argument:
+
+```php
+public function doSomething(
+    $foo = null)
+{
+    ...
+}
+```
+
+Example of a function that takes multiple arguments:
+
+```php
+public function doSomething(
+    $foo,
+    $bar = '',
+    $baz = null)
+{
+    ...
+}
+```
+
+- All properties and functions MUST be named using `camelCase`, NOT `snake_case`. (The _only_ exception to this rule is Instagram's server response property objects, meaning everything in the `src/Response/` folder, since _their_ server replies can use underscores.)
+- Private and protected properties/functions MUST be _prefixed_ with an underscore, to clearly show that they are internal inside the class and _cannot_ be used from the outside. But the PUBLIC properties/functions MUST _NEVER_ be prefixed with an underscore (_except_ the _obvious_, specially named, built-in PHP double-underscore ones such as `public function __construct()`). And also note that function _arguments_ (such as in setters) MUST NEVER be prefixed by underscores.
+
+Example of a class with proper function and property underscore prefixes for private/protected members, and with the proper function argument style:
+
+```php
+class Something
+{
+    public $publicProperty;
+    protected $_protectedProperty;
+    private $_privateProperty;
+
+    public function getProtectedProperty()
+    {
+        return $this->_protectedProperty;
+    }
+
+    public function setProtectedProperty(
+        $protectedProperty)
+    {
+        $this->_protectedProperty = $protectedProperty;
+    }
+
+    public function getPublicProperty()
+    {
+        return $this->_publicProperty;
+    }
+
+    public function setPublicProperty(
+        $publicProperty)
+    {
+        $this->publicProperty = $publicProperty;
+    }
+
+    protected function _somethingInternal()
+    {
+        ...
+    }
+
+    ...
+}
+```
+
+- All functions and variables MUST have descriptive names that document their purpose automatically. Use names like `$videoFilename` and `$deviceInfo` and so on, so that the code documents itself instead of needing tons of comments to explain what each step is doing.
+
+Examples of BAD variable names:
+
+```php
+$x = $po + $py;
+$w = floor($h * $ar);
+```
+
+Examples of GOOD variable names:
+
+```php
+$endpoint = $this->url.'?'.http_build_query($this->params);
+$this->_aspectRatio = (float) ($this->_width / $this->_height);
+$width = floor($this->_height * $this->_maxAspectRatio);
+```
+
+- All functions MUST have occasional comments that explain what they're doing in their various substeps. Look at our codebase and follow our commenting style.
+
+- Our comments start with a capital letter and end in punctuation, and describe the purpose in as few words as possible, such as: `// Default request options (immutable after client creation).`
+
+- All functions MUST do as little work as possible, so that they are easy to maintain and bugfix.
+
+Example of a GOOD function layout:
+
+```php
+function requestVideoURL(...);
+
+function uploadVideoChunks(...);
+
+function configureVideo(...);
+
+function uploadVideo(...)
+{
+    $url = $this->requestVideoURL();
+    if (...handle any errors from the previous function)
+
+    $uploadResult = $this->uploadVideoChunks($url, ...);
+
+    $this->configureVideo($uploadResult, ...);
+}
+```
+
+Example of a BAD function layout:
+
+```php
+function uploadVideo(...)
+{
+    // Request upload URL.
+    // Upload video data to URL.
+    // Configure its location property.
+    // Post it to a timeline.
+    // Call your grandmother.
+    // Make some tea.
+    // ...and 500 other lines of code.
+}
+```
+
+- All function parameter lists MUST be well-thought out so that they list the most important arguments FIRST and so that they are as SIMPLE as possible to EXTEND in the FUTURE, since Instagram's API changes occasionally.
+
+Avoid this kind of function template:
+
+```php
+function uploadVideo($videoFilename, $filter, $url, $caption, $usertags, $hashtags);
+```
+
+Make such multi-argument functions take future-extensible option-arrays instead, especially if you expect that more properties may be added in the future.
+
+So the above would instead be PROPERLY designed as follows:
+
+```php
+function uploadVideo($videoFilename, array $metadata);
+```
+
+Now users can just say `uploadVideo($videoFilename, ['hashtags'=>$hashtags]);`, and we can easily add more metadata fields in the future without ever breaking backwards-compatibility with projects that are using our function!
+
+### Function Documentation
+
+- All functions MUST have _COMPLETE_ PHPdoc doc-blocks. The critically important information is the single-sentence `summary-line` (ALWAYS), then the `detailed description` (if necessary), then the `@param` descriptions (if any), then the `@throws` (one for EVERY type of exception that it throws, even uncaught ones thrown from DEEPER functions called within this function), then the `@return` (if the function returns something), and lastly one or more `@see` if there's any need for a documentation reference to a URL or another function or class.
+
+Example of a properly documented function:
+
+```php
+    /**
+     * Generates a User Agent string from a Device (<< that is the REQUIRED ONE-SENTENCE summary-line).
+     *
+     * [All lines after that are the optional description. This function didn't need any,
+     *  but you CAN use this area to provide extra information describing things worth knowing.]
+     *
+     * @param \InstagramAPI\Devices\Device $device The Android device.
+     * @param string[]|null                $names (optional) Array of name-strings.
+     *
+     * @throws \InvalidArgumentException                  If the device parameter is invalid.
+     * @throws \InstagramAPI\Exception\InstagramException In case of invalid or failed API response.
+     *
+     * @return string
+     *
+     * @see otherFunction()
+     * @see http://some-url...
+     */
+    public static function buildUserAgent(
+        Device $device,
+        $names = null)
+    {
+        ...
+    }
+```
+
+- You MUST take EXTREMELY GOOD CARE to ALWAYS _perfectly_ document ALL parameters, the EXACT return-type, and ALL thrown exceptions. All other project developers RELY on the function-documentation ALWAYS being CORRECT! With incorrect documentation, other developers would make incorrect assumptions and _severe_ bugs would be introduced!
+
+### Exceptions
+
+- ALL thrown exceptions that can happen inside a function or in ANY of its SUB-FUNCTION calls MUST be documented as `@throws`, so that we get a COMPLETE OVERVIEW of ALL exceptions that may be thrown when we call the function. YES, that EVEN means exceptions that come from deeper function calls, whose exceptions are NOT being caught by your function and which will therefore bubble up if they're thrown by those deeper sub-functions!
+- Always remember that Exceptions WILL CRITICALLY BREAK ALL OTHER CODE AND STOP PHP'S EXECUTION if not handled or documented properly! They are a LOT of responsibility! So you MUST put a LOT OF TIME AND EFFORT into PROPERLY handling (_catching and doing something_) for ALL exceptions that your function should handle, AND adding PHPdoc _documentation_ about the ones that your function DOESN'T catch/handle internally and which WILL therefore bubble upwards and would possibly BREAK other code (which is EXACTLY what would happen if an exception ISN'T documented by you and someone then uses your bad function and doesn't "catch" your exception since YOU didn't tell them that it can be thrown)!
+- All of our internal exceptions derive from `\InstagramAPI\Exception\InstagramException`, so it's always safe to declare that one as a `@throws \InstagramAPI\Exception\InstagramException` if you're calling anything that throws exceptions based on our internal `src/Exception/*.php` system. But it's even better if you can pinpoint which exact exceptions are thrown, by looking at the functions you're calling and seeing their `@throws` documentation, WHICH OF COURSE DEPENDS ON PEOPLE HAVING WRITTEN PROPER `@throws` FOR THOSE OTHER FUNCTIONS SO THAT _YOU_ KNOW WHAT THE FUNCTIONS YOU'RE CALLING WILL THROW. DO YOU SEE _NOW_ HOW IMPORTANT IT IS TO DECLARE EXCEPTIONS PROPERLY AND TO _ALWAYS_ KEEP THAT LIST UP TO DATE
+- Whenever you are using an EXTERNAL LIBRARY that throws its own custom exceptions (meaning NOT one of the standard PHP ones such as `\Exception` or `\InvalidArgumentException`, etc), then you MUST ALWAYS re-wrap the exception into some appropriate exception from our own library instead, otherwise users will not be able to say `catch (\InstagramAPI\Exception\InstagramException $e)`, since the 3rd party exceptions wouldn't be derived from our base exception and wouldn't be caught, thus breaking the user's program. To solve that, look at the design of our `src/Exception/NetworkException.php`, which we use in `src/Client.php` to re-wrap all Guzzle exceptions into our own exception type instead. Read the source-code of our NetworkException and it will explain how to properly re-wrap 3rd party exceptions and how to ensure that your re-wrapped exception will give users helpful messages and helpful stack traces.
+
+
+# Contributing new endpoints
+
+In order to add endpoints to the API you will need to capture the requests first. For that, you can use any HTTPS proxy you want. You can find a lot of information about this on the internet. Remember that you need to install a root CA (Certificate Authority) in your device so that the proxy can decrypt the requests and show them to you.
+
+Also be aware that you cannot capture Instagram for iPhone's requests. The iPhone API parameters are totally different and they are NOT compatible with this Android API library! You MUST use a real Android APK when capturing requests!
+
+Once you have the endpoint and necessary parameters, how do you add them to this library? Easy, you can follow this example:
+
+```php
+    public function getAwesome(
+        array $userList)
+    {
+        return $this->ig->request('awesome/endpoint/')
+            ->setSignedPost(false)
+            ->addPost('_uuid', $this->ig->uuid)
+            ->addPost('user_ids', implode(',', $userList))
+            ->addPost('_csrftoken', $this->ig->client->getToken())
+            ->getResponse(new Response\AwesomeResponse());
+    }
+```
+
+In the example above you can see `('awesome/endpoint/')` which is the endpoint you captured. We are simulating a POST request, so you can add POST parameters easily by doing `->addPost('_uuid', $this->uuid)`.
+
+Which is basically:
+
+```php
+->addPost(key, value)
+```
+
+Where key is the name of the POST param, and value is whatever value the server requires for that parameter.
+
+Some of the requests are signed. This means there is a hash concatenated with the JSON. In order to make a signed request, we can enable or disable signing with the following line:
+
+```php
+->setSignedPost($isSigned)
+```
+
+`$isSigned` is boolean, so if you want a signed request, you simply set it to `true`.
+
+If the request is a GET request, you can add the GET query parameters like this (instead of using `addPost`):
+
+```php
+->addParam(key, value)
+```
+
+And finally, we always end with the `getResponse` function call, which will read the response and return an object with all of the server response values:
+
+```php
+->getResponse(new Response\AwesomeResponse());
+```
+
+Now you might be wondering how to create that response class? But there is nothing to worry about... it's very simple!
+
+Imagine that you have the following response:
+
+```json
+{"items": [{"user": {"is_verified": false, "has_anonymous_profile_picture": false, "is_private": false, "full_name": "awesome", "username": "awesome", "pk": "uid", "profile_pic_url": "profilepic"}, "large_urls": [], "caption": "", "thumbnail_urls": ["thumb1", "thumb2", "thumb3", "thumb4"]}], "status": "ok"}
+```
+
+You can use [http://jsoneditoronline.org](http://jsoneditoronline.org/) for a better visualization:
+
+<img src="https://s29.postimg.org/3xyopcbg7/insta_help.jpg" width="300">
+
+(Alternatively, if you're an advanced user, you can create an empty response-class (with no defined properties yet), and then use its `->printJson()` function to look at its contents in a beautifully readable way.)
+
+So your new `src/Response/AwesomeResponse.php` class should contain one `JSON_PROPERTY_MAP` property named `items`. Our magical [LazyJsonMapper](https://github.com/lazyjsonmapper/lazyjsonmapper) object mapping system needs a PHPdoc-style type-definition to tell us if the property is another class, a float, an int, a string, a string array, etc. By default, if you don't specify any type (if you set its value to `''`), it will treat the JSON value as whatever type PHP detected it as internally during JSON decoding (such as a string, int, float, bool, etc).
+
+In this scenario, your `src/Response/AwesomeResponse.php` file and its property definitions should look as follows, since we want to map `items` to an array of `Suggestion` objects:
+
+```php
+<?php
+
+namespace InstagramAPI\Response;
+
+use InstagramAPI\Response;
+
+class AwesomeResponse extends Response
+{
+    const JSON_PROPERTY_MAP = [
+        'items' => 'Model\Suggestion[]',
+    ];
+}
+```
+
+The `items` property will now expect an array of Suggestion model objects. And `src/Response/Model/Suggestion.php` should look like this:
+
+```php
+<?php
+
+namespace InstagramAPI\Response\Model;
+
+use InstagramAPI\AutoPropertyMapper;
+
+class Suggestion extends AutoPropertyMapper
+{
+    const JSON_PROPERTY_MAP = [
+        'media_infos'    => '',
+        'social_context' => '',
+        'algorithm'      => '',
+        'thumbnail_urls' => 'string[]',
+        'value'          => '',
+        'caption'        => '',
+        'user'           => 'User',
+        'large_urls'     => 'string[]',
+        'media_ids'      => '',
+        'icon'           => '',
+    ];
+}
+```
+
+Here in this `Suggestion` class you can see many variables that didn't appear in our example endpoint's response, but that's because many other requests _re-use_ the same object, and depending the request, their response contents may differ a bit. Also note that unlike the AwesomeResponse class, the actual Model objects (the files in in `src/Response/Model/`) _don't_ use the "Model\" prefix when referring to other model objects, since they are in the same namespace already.
+
+Also note that many of the properties above are defined as `''` (no type), which means "mixed/untyped". It simply means that the value is not forcibly converted to anything. That's how you should define most properties unless you have a specific reason to force anything to a specific type.
+
+It is also _extremely important_ that any properties relating to Media IDs, PKs, User PKs, etc, _must_ be declared as a `string`, otherwise they may be handled as a float/int which won't fit on 32-bit CPUs and will truncate the number, leading to the wrong data. Just look at all other Model objects that are already in this project, and be sure that any ID/PK fields in your own new Model object are properly tagged as `string` type too!
+
+Now you can test your new endpoint, in order to look at its response object:
+
+```
+$awesome = $i->getAwesome(['123']);
+$awesome->printJson(); // Look at the object data.
+$awesome->printPropertyDescriptions(); // Look at all defined properties.
+```
+
+And finally, how do you access the object's data? Via the magical [LazyJsonMapper](https://github.com/lazyjsonmapper/lazyjsonmapper), which your Response and Model objects inherit from! It automatically creates getters and setters for all properties, and has a million other features!
+
+```php
+$items = $awesome->getItems();
+$user = $items[0]->getUser();
+
+// LazyJsonMapper even lets you look at the JSON of specific sub-objects:
+$user->printJson();
+```
+
+Lastly, you may sometimes be implementing an endpoint which uses a nearly empty response with just the standard `status` and/or `message` (and `_messages`) fields, and no other fields. In that case, there's already a pre-made response which you should use: `GenericResponse`. Search the source code for that word and you'll find many endpoints where we use that basic response. Use it to easily add new endpoint implementations whenever there's no extra data to extract!
+
+We hope that you found this tutorial useful! :smile:

+Reciprocal Public License (RPL-1.5)
+
+Version 1.5, July 15, 2007
+
+Copyright (C) 2001-2007
+Technical Pursuit Inc.,
+All Rights Reserved.
+
+
+PREAMBLE
+
+The Reciprocal Public License (RPL) is based on the concept of reciprocity or,
+if you prefer, fairness.
+
+In short, this license grew out of a desire to close loopholes in previous open
+source licenses, loopholes that allowed parties to acquire open source software
+and derive financial benefit from it without having to release their
+improvements or derivatives to the community which enabled them. This occurred
+any time an entity did not release their application to a "third party".
+
+While there is a certain freedom in this model of licensing, it struck the
+authors of the RPL as being unfair to the open source community at large and to
+the original authors of the works in particular. After all, bug fixes,
+extensions, and meaningful and valuable derivatives were not consistently
+finding their way back into the community where they could fuel further, and
+faster, growth and expansion of the overall open source software base.
+
+While you should clearly read and understand the entire license, the essence of
+the RPL is found in two definitions: "Deploy" and "Required Components".
+
+Regarding deployment, under the RPL your changes, bug fixes, extensions, etc.
+must be made available to the open source community at large when you Deploy in
+any form -- either internally or to an outside party. Once you start running
+the software you have to start sharing the software.
+
+Further, under the RPL all components you author including schemas, scripts,
+source code, etc. -- regardless of whether they're compiled into a single
+binary or used as two halves of client/server application -- must be shared.
+You have to share the whole pie, not an isolated slice of it.
+
+In addition to these goals, the RPL was authored to meet the requirements of
+the Open Source Definition as maintained by the Open Source Initiative (OSI).
+
+The specific terms and conditions of the license are defined in the remainder
+of this document.
+
+

+2.0 Acceptance Of License. You are not required to accept this License since
+you have not signed it, however nothing else grants you permission to use,
+copy, distribute, modify, or create derivatives of either the Software or any
+Extensions created by a Contributor. These actions are prohibited by law if

+Section 6 below, each Contributor hereby grants You a world-wide, royalty-
+free, non-exclusive license, subject to said Contributor's intellectual
+property rights, and any third party intellectual property claims derived from
+the Licensed Software under this License, to do the following:
+
+4.1 Use, reproduce, modify, display, perform, sublicense and distribute any
+Extensions Deployed by such Contributor or portions thereof, in both Source

+
+5.0 Exclusions From License Grant. Nothing in this License shall be deemed to
+grant any rights to trademarks, copyrights, patents, trade secrets or any
+other intellectual property of Licensor or any Contributor except as expressly
+stated herein. Except as expressly stated in Sections 3 and 4, no other patent
+rights, express or implied, are granted herein. Your Extensions may require
+additional patent licenses from Licensor or Contributors which each may grant
+in its sole discretion. No right is granted to the trademarks of Licensor or
+any Contributor even if such marks are included in the Licensed Software.
+Nothing in this License shall be interpreted to prohibit Licensor from
+licensing under different terms from this License any code that Licensor
+otherwise would have a right to license.
+
+5.1 You expressly acknowledge and agree that although Licensor and each
+Contributor grants the licenses to their respective portions of the Licensed
+Software set forth herein, no assurances are provided by Licensor or any
+Contributor that the Licensed Software does not infringe the patent or other
+intellectual property rights of any other entity. Licensor and each
+Contributor disclaim any liability to You for claims brought by any other
+entity based on infringement of intellectual property rights or otherwise. As
+a condition to exercising the rights and licenses granted hereunder, You
+hereby assume sole responsibility to secure any other intellectual property
+rights needed, if any. For example, if a third party patent license is
+required to allow You to distribute the Licensed Software, it is Your
+responsibility to acquire that license before distributing the Licensed
+Software.
+
+6.0 Your Obligations And Grants. In consideration of, and as an express
+condition to, the licenses granted to You under this License You hereby agree
+that any Modifications, Derivative Works, or Required Components (collectively
+Extensions) that You create or to which You contribute are governed by the
+terms of this License including, without limitation, Section 4. Any Extensions
+that You create or to which You contribute must be Deployed under the terms of
+this License or a future version of this License released under Section 7. You
+hereby grant to Licensor and all third parties a world-wide, non-exclusive,
+royalty-free license under those intellectual property rights You own or
+control to use, reproduce, display, perform, modify, create derivatives,
+sublicense, and distribute Licensed Software, in any form. Any Extensions You
+make and Deploy must have a distinct title so as to readily tell any
+subsequent user or Contributor that the Extensions are by You. You must
+include a copy of this License or directions on how to obtain a copy with
+every copy of the Extensions You distribute. You agree not to offer or impose
+any terms on any Source Code or executable version of the Licensed Software,
+or its Extensions that alter or restrict the applicable version of this
+License or the recipients' rights hereunder.
+
+6.1 Availability of Source Code. You must make available, under the terms of
+this License, the Source Code of any Extensions that You Deploy, via an
+Electronic Distribution Mechanism. The Source Code for any version that You
+Deploy must be made available within one (1) month of when you Deploy and must
+remain available for no less than twelve (12) months after the date You cease
+to Deploy. You are responsible for ensuring that the Source Code to each
+version You Deploy remains available even if the Electronic Distribution
+Mechanism is maintained by a third party. You may not charge a fee for any
+copy of the Source Code distributed under this Section in excess of Your
+actual cost of duplication and distribution of said copy.
+
+6.2 Description of Modifications. You must cause any Modifications that You
+create or to which You contribute to be documented in the Source Code, clearly
+describing the additions, changes or deletions You made. You must include a
+prominent statement that the Modifications are derived, directly or indirectly,
+from the Licensed Software and include the names of the Licensor and any
+Contributor to the Licensed Software in (i) the Source Code and (ii) in any
+notice displayed by the Licensed Software You distribute or in related
+documentation in which You describe the origin or ownership of the Licensed
+Software. You may not modify or delete any pre-existing copyright notices,
+change notices or License text in the Licensed Software without written
+permission of the respective Licensor or Contributor.
+
+6.3 Intellectual Property Matters.
+
+a. Third Party Claims. If You have knowledge that a license to a third party's
+intellectual property right is required to exercise the rights granted by this
+License, You must include a human-readable file with Your distribution that
+describes the claim and the party making the claim in sufficient detail that a
+recipient will know whom to contact.
+
+b. Contributor APIs. If Your Extensions include an application programming
+interface ("API") and You have knowledge of patent licenses that are
+reasonably necessary to implement that API, You must also include this
+information in a human-readable file supplied with Your distribution.
+
+c. Representations. You represent that, except as disclosed pursuant to 6.3(a)
+above, You believe that any Extensions You distribute are Your original
+creations and that You have sufficient rights to grant the rights conveyed by
+this License.
+
+6.4 Required Notices.
+
+a. License Text. You must duplicate this License or instructions on how to
+acquire a copy in any documentation You provide along with the Source Code of
+any Extensions You create or to which You contribute, wherever You describe
+recipients' rights relating to Licensed Software.
+
+b. License Notice. You must duplicate any notice contained in EXHIBIT A (the
+"License Notice") in each file of the Source Code of any copy You distribute
+of the Licensed Software and Your Extensions. If You create an Extension, You
+may add Your name as a Contributor to the Source Code and accompanying
+documentation along with a description of the contribution. If it is not
+possible to put the License Notice in a particular Source Code file due to its
+structure, then You must include such License Notice in a location where a
+user would be likely to look for such a notice.
+
+c. Source Code Availability. You must notify the software community of the
+availability of Source Code to Your Extensions within one (1) month of the date
+You initially Deploy and include in such notification a description of the
+Extensions, and instructions on how to acquire the Source Code. Should such
+instructions change you must notify the software community of revised
+instructions within one (1) month of the date of change. You must provide
+notification by posting to appropriate news groups, mailing lists, weblogs, or
+other sites where a publicly accessible search engine would reasonably be
+expected to index your post in relationship to queries regarding the Licensed
+Software and/or Your Extensions.
+
+d. User-Visible Attribution. You must duplicate any notice contained in
+EXHIBIT B (the "User-Visible Attribution Notice") in each user-visible display
+of the Licensed Software and Your Extensions which delineates copyright,
+ownership, or similar attribution information. If You create an Extension,
+You may add Your name as a Contributor, and add Your attribution notice, as an
+equally visible and functional element of any User-Visible Attribution Notice
+content. To ensure proper attribution, You must also include such User-Visible
+Attribution Notice in at least one location in the Software documentation
+where a user would be likely to look for such notice.
+
+6.5 Additional Terms. You may choose to offer, and charge a fee for, warranty,
+support, indemnity or liability obligations to one or more recipients of
+Licensed Software. However, You may do so only on Your own behalf, and not on
+behalf of the Licensor or any Contributor except as permitted under other
+agreements between you and Licensor or Contributor. You must make it clear that
+any such warranty, support, indemnity or liability obligation is offered by You
+alone, and You hereby agree to indemnify the Licensor and every Contributor for
+any liability plus attorney fees, costs, and related expenses due to any such
+action or claim incurred by the Licensor or such Contributor as a result of
+warranty, support, indemnity or liability terms You offer.
+
+6.6 Conflicts With Other Licenses. Where any portion of Your Extensions, by
+virtue of being Derivative Works of another product or similar circumstance,
+fall under the terms of another license, the terms of that license should be
+honored however You must also make Your Extensions available under this
+License. If the terms of this License continue to conflict with the terms of
+the other license you may write the Licensor for permission to resolve the
+conflict in a fashion that remains consistent with the intent of this License.
+Such permission will be granted at the sole discretion of the Licensor.
+
+7.0 Versions of This License. Licensor may publish from time to time revised
+versions of the License. Once Licensed Software has been published under a
+particular version of the License, You may always continue to use it under the
+terms of that version. You may also choose to use such Licensed Software under
+the terms of any subsequent version of the License published by Licensor. No
+one other than Licensor has the right to modify the terms applicable to
+Licensed Software created under this License.
+
+7.1 If You create or use a modified version of this License, which You may do
+only in order to apply it to software that is not already Licensed Software
+under this License, You must rename Your license so that it is not confusingly
+similar to this License, and must make it clear that Your license contains
+terms that differ from this License. In so naming Your license, You may not
+use any trademark of Licensor or of any Contributor. Should Your modifications
+to this License be limited to alteration of a) Section 13.8 solely to modify
+the legal Jurisdiction or Venue for disputes, b) EXHIBIT A solely to define
+License Notice text, or c) to EXHIBIT B solely to define a User-Visible
+Attribution Notice, You may continue to refer to Your License as the
+Reciprocal Public License or simply the RPL.
+
+8.0 Disclaimer of Warranty. LICENSED SOFTWARE IS PROVIDED UNDER THIS LICENSE
+ON AN "AS IS" BASIS, WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESS OR IMPLIED,
+INCLUDING, WITHOUT LIMITATION, WARRANTIES THAT THE LICENSED SOFTWARE IS FREE
+OF DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING.
+FURTHER THERE IS NO WARRANTY MADE AND ALL IMPLIED WARRANTIES ARE DISCLAIMED
+THAT THE LICENSED SOFTWARE MEETS OR COMPLIES WITH ANY DESCRIPTION OF
+PERFORMANCE OR OPERATION, SAID COMPATIBILITY AND SUITABILITY BEING YOUR
+RESPONSIBILITY. LICENSOR DISCLAIMS ANY WARRANTY, IMPLIED OR EXPRESSED, THAT
+ANY CONTRIBUTOR'S EXTENSIONS MEET ANY STANDARD OF COMPATIBILITY OR DESCRIPTION
+OF PERFORMANCE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LICENSED SOFTWARE IS WITH YOU. SHOULD LICENSED SOFTWARE PROVE DEFECTIVE IN ANY
+RESPECT, YOU (AND NOT THE LICENSOR OR ANY OTHER CONTRIBUTOR) ASSUME THE COST
+OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. UNDER THE TERMS OF THIS
+LICENSOR WILL NOT SUPPORT THIS SOFTWARE AND IS UNDER NO OBLIGATION TO ISSUE
+UPDATES TO THIS SOFTWARE. LICENSOR HAS NO KNOWLEDGE OF ERRANT CODE OR VIRUS IN
+THIS SOFTWARE, BUT DOES NOT WARRANT THAT THE SOFTWARE IS FREE FROM SUCH ERRORS
+OR VIRUSES. THIS DISCLAIMER OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS
+LICENSE. NO USE OF LICENSED SOFTWARE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS
+DISCLAIMER.
+
+9.0 Limitation of Liability. UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY,
+WHETHER TORT (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL THE
+LICENSOR, ANY CONTRIBUTOR, OR ANY DISTRIBUTOR OF LICENSED SOFTWARE, OR ANY
+SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR ANY INDIRECT,
+SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY CHARACTER INCLUDING,
+WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL, WORK STOPPAGE, COMPUTER
+FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER COMMERCIAL DAMAGES OR LOSSES,
+EVEN IF SUCH PARTY SHALL HAVE BEEN INFORMED OF THE POSSIBILITY OF SUCH
+DAMAGES. THIS LIMITATION OF LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH
+OR PERSONAL INJURY RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT
+APPLICABLE LAW PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE
+EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS
+EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.
+
+10.0 High Risk Activities. THE LICENSED SOFTWARE IS NOT FAULT-TOLERANT AND IS
+NOT DESIGNED, MANUFACTURED, OR INTENDED FOR USE OR DISTRIBUTION AS ON-LINE
+CONTROL EQUIPMENT IN HAZARDOUS ENVIRONMENTS REQUIRING FAIL-SAFE PERFORMANCE,
+SUCH AS IN THE OPERATION OF NUCLEAR FACILITIES, AIRCRAFT NAVIGATION OR
+COMMUNICATIONS SYSTEMS, AIR TRAFFIC CONTROL, DIRECT LIFE SUPPORT MACHINES, OR
+WEAPONS SYSTEMS, IN WHICH THE FAILURE OF THE LICENSED SOFTWARE COULD LEAD
+DIRECTLY TO DEATH, PERSONAL INJURY, OR SEVERE PHYSICAL OR ENVIRONMENTAL DAMAGE
+("HIGH RISK ACTIVITIES"). LICENSOR AND CONTRIBUTORS SPECIFICALLY DISCLAIM ANY
+EXPRESS OR IMPLIED WARRANTY OF FITNESS FOR HIGH RISK ACTIVITIES.
+
+11.0 Responsibility for Claims. As between Licensor and Contributors, each
+party is responsible for claims and damages arising, directly or indirectly,
+out of its utilization of rights under this License which specifically
+disclaims warranties and limits any liability of the Licensor. This paragraph
+is to be used in conjunction with and controlled by the Disclaimer Of
+Warranties of Section 8, the Limitation Of Damages in Section 9, and the
+disclaimer against use for High Risk Activities in Section 10. The Licensor
+has thereby disclaimed all warranties and limited any damages that it is or
+may be liable for. You agree to work with Licensor and Contributors to
+distribute such responsibility on an equitable basis consistent with the terms
+of this License including Sections 8, 9, and 10. Nothing herein is intended or
+shall be deemed to constitute any admission of liability.
+
+12.0 Termination. This License and all rights granted hereunder will terminate
+immediately in the event of the circumstances described in Section 13.6 or if
+applicable law prohibits or restricts You from fully and or specifically
+complying with Sections 3, 4 and/or 6, or prevents the enforceability of any
+of those Sections, and You must immediately discontinue any use of Licensed
+Software.
+
+12.1 Automatic Termination Upon Breach. This License and the rights granted
+hereunder will terminate automatically if You fail to comply with the terms
+herein and fail to cure such breach within thirty (30) days of becoming aware
+of the breach. All sublicenses to the Licensed Software that are properly
+granted shall survive any termination of this License. Provisions that, by
+their nature, must remain in effect beyond the termination of this License,
+shall survive.
+
+12.2 Termination Upon Assertion of Patent Infringement. If You initiate
+litigation by asserting a patent infringement claim (excluding declaratory
+judgment actions) against Licensor or a Contributor (Licensor or Contributor
+against whom You file such an action is referred to herein as "Respondent")
+alleging that Licensed Software directly or indirectly infringes any patent,
+then any and all rights granted by such Respondent to You under Sections 3 or
+4 of this License shall terminate prospectively upon sixty (60) days notice
+from Respondent (the "Notice Period") unless within that Notice Period You
+either agree in writing (i) to pay Respondent a mutually agreeable reasonably
+royalty for Your past or future use of Licensed Software made by such
+Respondent, or (ii) withdraw Your litigation claim with respect to Licensed
+Software against such Respondent. If within said Notice Period a reasonable
+royalty and payment arrangement are not mutually agreed upon in writing by the
+parties or the litigation claim is not withdrawn, the rights granted by
+Licensor to You under Sections 3 and 4 automatically terminate at the
+expiration of said Notice Period.
+
+12.3 Reasonable Value of This License. If You assert a patent infringement
+claim against Respondent alleging that Licensed Software directly or
+indirectly infringes any patent where such claim is resolved (such as by
+license or settlement) prior to the initiation of patent infringement
+litigation, then the reasonable value of the licenses granted by said
+Respondent under Sections 3 and 4 shall be taken into account in determining
+the amount or value of any payment or license.
+
+12.4 No Retroactive Effect of Termination. In the event of termination under
+this Section all end user license agreements (excluding licenses to
+distributors and resellers) that have been validly granted by You or any
+distributor hereunder prior to termination shall survive termination.
+
+13.0 Miscellaneous.
+
+13.1 U.S. Government End Users. The Licensed Software is a "commercial item,"
+as that term is defined in 48 C.F.R. 2.101 (Oct. 1995), consisting of
+"commercial computer software" and "commercial computer software

+
+----------
+## Installation
+
+### Dependencies
+
+Install/enable the required php extensions and dependencies. You can learn how to do so [here](https://github.com/mgp25/Instagram-API/wiki/Dependencies).
+
+### Install this library
+We use composer to distribute our code effectively and easily. If you do not already have composer installed, you can download and install it here [here](https://getcomposer.org/download/).
+
+Once you have composer installed, you can do the following:
+```sh
+composer require mgp25/instagram-php
+```
+
+```php
+require __DIR__.'/../vendor/autoload.php';
+
+$ig = new \InstagramAPI\Instagram();
+```
+
+If you want to test new and possibly unstable code that is in the master branch, and which hasn't yet been released, then you can do the following (at your own risk):
+
+```sh
+composer require mgp25/instagram-php dev-master
+```
+
+#### _Warning about moving data to a different server_
+
+_Composer checks your system's capabilities and selects libraries based on your **current** machine (where you are running the `composer` command). So if you run Composer on machine `A` to install this library, it will check machine `A`'s capabilities and will install libraries appropriate for that machine (such as installing the PHP 7+ versions of various libraries). If you then move your whole installation to machine `B` instead, it **will not work** unless machine `B` has the **exact** same capabilities (same or higher PHP version and PHP extensions)! Therefore, you should **always** run the Composer-command on your intended target machine instead of your local machine._
+
+## Examples

+## Code of Conduct
+
+This project adheres to the Contributor Covenant [code of conduct](CODE_OF_CONDUCT.md).
+By participating, you are expected to uphold this code.

+
+## How do I contribute
+
+If you would like to contribute to this project, please feel free to submit a pull request.
+
+Before you do, take a look at the [contributing guide](https://github.com/mgp25/Instagram-API/blob/master/CONTRIBUTING.md).
+
+## Why did I make this API?
+
+After legal measures, Facebook, WhatsApp and Instagram blocked my accounts.
+In order to use Instagram on my phone I needed a new phone, as they banned my UDID, so that is basically why I made this API.
+
+### What is Instagram?
+According to [the company](https://instagram.com/about/faq/):
+
+> "Instagram is a fun and quirky way to share your life with friends through a series of pictures. Snap a photo with your mobile phone, then choose a filter to transform the image into a memory to keep around forever. We're building Instagram to allow you to experience moments in your friends' lives through pictures as they happen. We imagine a world more connected through photos."
+
+# License
+
+In order help ensure fairness and sharing, this library is dual-licensed. Be
+aware that _all_ usage, unless otherwise specified, is under the **RPL-1.5**
+license!
+
+- Reciprocal Public License 1.5 (RPL-1.5): https://opensource.org/licenses/RPL-1.5
+
+You should read the _entire_ license; especially the `PREAMBLE` at the
+beginning. In short, the word `reciprocal` means "giving something back in
+return for what you are getting". It is _**not** a freeware license_. This
+license _requires_ that you open-source _all_ of your own source code for _any_
+project which uses this library! Creating and maintaining this library is
+endless hard work for us. That's why there is _one_ simple requirement for you:
+Give _something_ back to the world. Whether that's code _or_ financial support
+for this project is entirely up to you, but _nothing else_ grants you _any_
+right to use this library.
+
+Furthermore, the library is _also_ available _to certain entities_ under a
+modified version of the RPL-1.5, which has been modified to allow you to use the
+library _without_ open-sourcing your own project. The modified license
+(see [LICENSE_PREMIUM](https://github.com/mgp25/Instagram-API/blob/master/LICENSE_PREMIUM))
+is granted to certain entities, at _our_ discretion, and for a _limited_ period
+of time (unless otherwise agreed), pursuant to our terms. Currently, we are
+granting this license to all
+"[premium subscribers](https://github.com/mgp25/Instagram-API/issues/2655)" for
+the duration of their subscriptions. You can become a premium subscriber by
+either contributing substantial amounts of high-quality code, or by subscribing
+for a fee. This licensing ensures fairness and stimulates the continued growth
+of this library through both code contributions and the financial support it
+needs.
+
+You are not required to accept this License since you have not signed it,
+however _nothing else_ grants you permission to _use_, copy, distribute, modify,
+or create derivatives of either the Software (this library) or any Extensions
+created by a Contributor. These actions are prohibited by law if you do not
+accept this License. Therefore, by performing any of these actions You indicate
+Your acceptance of this License and Your agreement to be bound by all its terms
+and conditions. IF YOU DO NOT AGREE WITH ALL THE TERMS AND CONDITIONS OF THIS
+LICENSE DO NOT USE, MODIFY, CREATE DERIVATIVES, OR DISTRIBUTE THE SOFTWARE. IF
+IT IS IMPOSSIBLE FOR YOU TO COMPLY WITH ALL THE TERMS AND CONDITIONS OF THIS
+LICENSE THEN YOU CAN NOT USE, MODIFY, CREATE DERIVATIVES, OR DISTRIBUTE THE
+SOFTWARE.
+
+# Terms and conditions
+
+- You will NOT use this API for marketing purposes (spam, botting, harassment, massive bulk messaging...).
+- We do NOT give support to anyone who wants to use this API to send spam or commit other crimes.
+- We reserve the right to block any user of this repository that does not meet these conditions.
+
+## Legal
+
+This code is in no way affiliated with, authorized, maintained, sponsored or endorsed by Instagram or any of its affiliates or subsidiaries. This is an independent and unofficial API. Use at your own risk.

+ * This example demonstrates how to use and customize user settings storages.
+ *
+ * By default, if you don't give us any custom configuration, we will always use
+ * the "File" storage backend, which keeps all data in regular files on disk. It
+ * is a rock-solid backend and will be very good for most people.
+ *
+ * However, other people may want to use something more advanced, such as one of
+ * the other built-in storage backends ("MySQL", "SQLite" and "Memcached"). Or
+ * perhaps you'd even like to build your own backend (doing so is very easy).
+ */
+
+echo "You are not supposed to execute this script. Read it in a text editor to see various storage methods.\n";
+exit;
+
+// These points will give you a basic overview of the process. But you should
+// read the code in src/Settings/ for the full details. It is well documented.
+
+// 1. Choosing a built-in storage backend (one of "file", "mysql", "sqlite" or
+// "memcached"), and using the automatic, default settings for that backend:
+$ig = new \InstagramAPI\Instagram($debug, $truncatedDebug, [
+    'storage' => 'mysql',
+]);
+
+// 2. You can read src/Settings/Factory.php for valid settings for each backend.
+// Here's an example of how to change the default storage location for "file":
+$ig = new \InstagramAPI\Instagram($debug, $truncatedDebug, [
+    'storage'    => 'file',
+    'basefolder' => 'some/path/',
+]);
+
+// 3. And here's an example of how to change the default database filename and
+// the default database table name for the "sqlite" backend:
+$ig = new \InstagramAPI\Instagram($debug, $truncatedDebug, [
+    'storage'     => 'sqlite',
+    'dbfilename'  => 'some/path/foo.db',
+    'dbtablename' => 'mysettings',
+]);
+
+// 4. If you read src/Settings/Factory.php, you'll notice that you can choose
+// the storage backends and most of their parameters via the command line or
+// environment variables instead. For example: "SETTINGS_STORAGE=mysql php
+// yourscript.php" would set the "storage" parameter via the environment, and
+// typing "php yourscript.php --settings_storage=mysql" would set it via the
+// command line. The command-line arguments have the highest precedence, then
+// the environment variables, and lastly the code within your script. This
+// precedence order is so that you can easily override your script's code to
+// test other backends or change their parameters without modifying your code.
+
+// 5. Very advanced users can look in src/Settings/StorageHandler.php to read
+// about hasUser(), moveUser() and deleteUser(). Three very, VERY DANGEROUS
+// commands which let you rename or delete account settings in your storage.
+// Carefully read through their descriptions and use them wisely. If you're sure
+// that you dare to use them, then you can access them via $ig->settings->...
+
+// 6. Yet another super advanced topic is the ability to copy data between
+// backends. For example if you want to move all of your data from a File
+// backend to a database, or vice versa. That kind of action is not supported
+// natively by us, but you CAN do it by directly interfacing with the storages!
+
+// First, you MUST manually build a list of all users you want to migrate.
+// You can either hardcode this list. Or get it via something like a directory
+// scan (to look at existing folders in a File backend storage path), or a
+// database query to get all "username" values from the old database. If you're
+// using a database, you will have to connect to it manually and query it
+// yourself! There's no way to do it automatically! Just build this array any
+// way you want to do it!
+$migrateUsers = [
+    'someuser',
+    'another.user',
+    'very_awesome_user123',
+];
+
+// Secondly, you must connect to your old and new storages. These are just
+// example values. The array format is the exact same as what's given to the
+// `Instagram()` constructor! And if you give an empty array, you'll use the
+// same default File backend that the main class uses! So if you want to migrate
+// from that, you should just set oldStorage to `createHandler([])`!
+$oldStorage = \InstagramAPI\Settings\Factory::createHandler([
+    'storage'     => 'sqlite',
+    'dbfilename'  => 'app/instagram.sqlite',
+    'dbtablename' => 'instagram_sessions',
+]);
+$newStorage = \InstagramAPI\Settings\Factory::createHandler([
+    'storage'     => 'file',
+    'basefolder'  => 'some/path/',
+]);
+
+// Now just run the migration process. This will copy all cookies and settings
+// from the old storage to the new storage, for all of the "migrateUsers".
+foreach ($migrateUsers as $user) {
+    if (!$oldStorage->hasUser($user)) {
+        die("Unable to migrate '{$user}' from old storage (user doesn't exist).\n");
+    }
+
+    echo "Migrating '{$user}'.\n";
+
+    $oldStorage->setActiveUser($user);
+    $newStorage->setActiveUser($user);
+
+    $newStorage->setCookies((string) $oldStorage->getCookies());
+    foreach (\InstagramAPI\Settings\StorageHandler::PERSISTENT_KEYS as $key) {
+        $newStorage->set($key, (string) $oldStorage->get($key));
+    }
+}
+
+// 7. Lastly... if you want to implement your own completely CUSTOM STORAGE,
+// then you simply have to do one thing: Implement the StorageInterface class
+// interface. But be very sure to STRICTLY follow ALL rules for storage backends
+// described in that interface's docs, otherwise your custom backend WON'T work.
+//
+// See the overview in src/Settings/StorageInterface.php, and then read through
+// the various built-in storage backends in src/Settings/Storage/ to see perfect
+// implementations that completely follow the required interface specification.
+//
+// Also note that PDO-based backends should be derived from our "PDOStorage"
+// storage sub-component, so that the logic is perfectly implemented and not
+// duplicated. That's exactly how our "sqlite" and "mysql" PDO backends work!
+//
+// To use your custom storage backend, you would simply create your own class
+// similar to the built-in backends. But do NOT put your own class in our
+// src/Settings/Storage/ folder. Store your class inside your own project.
+//
+// Then simply provide your custom storage class instance as the storage class:
+$ig = new \InstagramAPI\Instagram($debug, $truncatedDebug, [
+    'storage' => 'custom',
+    'class'   => new MyCustomStorage(), // Whatever you've named your class.
+]);
+
+// That's it! This should get you started on your journey. :-)
+
+// And please think about contributing your WELL-WRITTEN storage backends to
+// this project! If you had a reason to write your own, then there's probably
+// someone else out there with the same need. Remember to SHARE with the open
+// source community! ;-)

+/**
+ * Internal list of verified Android devices.
+ *
+ * @author SteveJobzniak (https://github.com/SteveJobzniak)
+ *
+ * This is a list of popular, modern Android phones, all VERIFIED to support
+ * receiving the max-resolution videos from Instagram's API replies. This list
+ * has to be hand-crafted, because bad devices only receive low-resolution
+ * videos! Instagram's API looks at device MODEL when deciding to deliver HD.
+ *
+ * The goal with this list is to have a list of ~10 modern phones which we only
+ * have to refresh every few years, as they slip away into obscurity.
+ *
+ * Here are the rules for building the list:
+ *
+ * - Find a top-list of the best Android phones for [current year].
+ * - Only select devices with super high resolution screens (at least 1080p+).
+ * - Find the model at https://www.handsetdetection.com/properties/devices.
+ * - Some phones have tons of sub-models. Find the phone on Amazon and look at
+ *   the details to find sub-model identifier for the most popular US variant!
+ * - Research the model's popularity. For example, NEVER include a Samsung phone
+ *   with an "X" suffix (such as SM-G935X). Those are STORE DEMO units.
+ * - Check if they've recorded any Instagram user agent. If there are multiple
+ *   agents for Instagram, compare them all carefully and pick the latest.
+ * - Look closely to make sure the string wasn't truncated or modified on their
+ *   site. I've seen phones lacking the locale and final parenthesis, for
+ *   example. Or strings that are all-lowercase. DO NOT USE THOSE!
+ * - Verify the device details by doing a Google search for the model identifier
+ *   you found in the user-agent, to verify all specs match the real device.
+ * - Enter good models below in the same format as the other devices. Triple and
+ *   quadruple check that it is 100% CORRECT for that device.
+ * - Always enter the EXACT Android version that the user agent was seen with on
+ *   the website above, which is usually the OS version the phone released with.
+ * - The Android version is the first part of the agent, such as "23/6.0.1".
+ *
+ * Here's an example string:
+ * "Instagram 10.9.0 Android (23/6.0.1; 480dpi; 1080x1776; LENOVO/Lenovo; Lenovo P2a42; P2a42; qcom; fr_FR)".
+ *
+ * The format is made via the android.os.Build library:
+ * "Instagram %s Android (%s/%s; %s; %s; %s/%s; %s; %s; %s)
+ * 1. Instagram VERSION.
+ * 2. Android API VERSION (Build$VERSION.SDK_INT)
+ * 3. Android VERSION (Build$VERSION.RELEASE)
+ * 4. DPI.
+ * 5. Display Resolution.
+ * 6. MANUFACTURER.
+ * 7 (optional). BRAND (this "/"-portion with a brand doesn't always exist).
+ * 8. MODEL.
+ * 9. DEVICE.
+ * 10. CPU (Build.HARDWARE)
+ * 11. Language (Build.LOCALE).
+ *
+ * We only want the part within parenthesis, and we ignore the locale.
+ *
+ * That gives us the following string:
+ * "23/6.0.1; 480dpi; 1080x1776; LENOVO/Lenovo; Lenovo P2a42; P2a42; qcom".
+ *
+ * However, note that the device above isn't at least 1920x1080. Don't use it.
+ *
+ *
+ * When you have a "possibly good" agent, you must finally TEST IT: Use the
+ * "devtools/checkDevices.php" developer script to check your agent and verify
+ * that Instagram detects it as a high-resolution device and gives it HD videos!
+ *
+ *
+ * LASTLY, YOU MUST UNDERSTAND THE FOLLOWING: THE DEVICE LIST BELOW IS MEANT TO
+ * BE A "SNAPSHOT" OF DEVICES AND THEIR ANDROID VERSIONS AT THAT MOMENT IN TIME.
+ * WE ARE *ONLY* SUPPOSED TO *ADD* NEW DEVICES TO IT OR COMPLETELY *DELETE* OLD
+ * DEVICES. DO *NOT* "EDIT" THE LIST TO TRY TO "IMPROVE" OR "UPDATE" ANDROID
+ * VERSIONS OR *ANYTHING* ELSE ABOUT AN EXISTING DEVICE. EDITING EVEN A *SINGLE*
+ * BYTE WILL CAUSE *ALL* USERS OF THAT DEVICE TO BE LOGGED OUT AND *RE-ASSIGNED*
+ * TO A BRAND NEW PHONE HARDWARE FINGERPRINT AND A DIFFERENT RANDOM DEVICE. THAT
+ * BEHAVIOR IS INTENTIONAL AND *BY DESIGN*. IT ALLOWS US TO SAFELY BLACKLIST BAD
+ * DEVICES AND IT DISCOURAGES DUMB, FRIVOLOUS "UPGRADES", THUS ENSURING THAT WE
+ * *ONLY* IDENTIFY OUR DEVICES WITH THE ACTUAL *ANDROID* VERSION THEY *SHIPPED*
+ * WITH, WHICH IS THE SAFEST WAY TO IDENTIFY OUR VIRTUAL DEVICES. MOST REAL
+ * USERS DON'T UPGRADE ANDROID OS BEYOND WHAT THE PHONE ORIGINALLY SHIPPED WITH.
+ *
+ *
+ * THIS DEVICE LIST IS CRITICAL TO THE OPERATION OF THE API. DO NOT CONTRIBUTE
+ * TO THIS LIST IF YOU DON'T UNDERSTAND *ALL* INSTRUCTIONS ABOVE. PERFECTLY. ALL
+ * CONTRIBUTIONS MUST INCLUDE THE RELEASE DATE, HANDSETDETECTION AND A LINK TO A
+ * PAGE (SUCH AS AMAZON) FOR THAT EXACT MODEL SPECIFIER, AS SEEN BELOW, SO THAT
+ * WE CAN VALIDATE ALL AGENTS TO SEE THAT YOU AREN'T ADDING AN INCORRECTLY
+ * WRITTEN OR UNPOPULAR DEVICE AGENT WHICH WILL GET US BANNED BY INSTAGRAM!

+     * Available `$options` parameters:
+     *
+     * - "targetFeed" (int): One of the FEED_X constants. MUST be used if you're
+     *   targeting stories. Defaults to `Constants::FEED_TIMELINE`.
+     *
+     * - "horCropFocus" (int): Crop focus position (-50 .. 50) when cropping
+     *   horizontally (reducing width). Uses intelligent guess if not set.
+     *
+     * - "verCropFocus" (int): Crop focus position (-50 .. 50) when cropping
+     *   vertically (reducing height). Uses intelligent guess if not set.
+     *
+     * - "minAspectRatio" (float): Minimum allowed aspect ratio. Uses
+     *   auto-selected class constants (with the correct, legal Instagram
+     *   aspect ratio limits for your chosen target feed) if not set.
+     *
+     * - "maxAspectRatio" (float): Maximum allowed aspect ratio. Uses
+     *   auto-selected class constants (with the correct, legal Instagram
+     *   aspect ratio limits for your chosen target feed) if not set.
+     *
+     * - "forceAspectRatio" (float|int): Tell the media processor to enforce a
+     *   specific aspect ratio target. This custom value MUST be within the
+     *   "minAspectRatio" to "maxAspectRatio" range! NOTE: When your goal is to
+     *   generate a custom media aspect ratio, you should normally ONLY specify
+     *   THIS parameter and should NEVER tamper with the min/max aspect ratio
+     *   limits! Because when you're specifying a custom forced ratio here, we
+     *   WILL ALWAYS verify/process the media as-necessary to fit your desired
+     *   ratio (EVEN if the input media was "already valid" within the overall,
+     *   larger legal min/max ratio ranges). ALSO NOTE: We WON'T process input
+     *   media when it's already VERY close to the desired target ratio. The
+     *   ONLY custom aspect ratio value that is 100% guaranteed to be FULLY
+     *   ENFORCED is `1.0` (square). If you specify ANY other ratio, we will
+     *   accept a VERY SMALL deviation when the media is already almost exactly
+     *   at the desired ratio. This is done to prevent pointless "impossible
+     *   processing", since achieving EXACT non-`1.0` ratios is almost always
+     *   IMPOSSIBLE, so it's not worth trying with media that's already very
+     *   close. The reason why non-`1.0` ratios are impossibly hard to hit in
+     *   MOST cases, is because pixels cannot be subdivided into smaller
+     *   fractions than "1 whole pixel", so in most cases when we ask for
+     *   something like `1.25385` ratio and we have an input file such as
+     *   `640x512` (`1.25` ratio), it is PHYSICALLY IMPOSSIBLE to achieve a
+     *   `1.25385` ratio with that input and we could AT BEST reach a tiny
+     *   fraction away from that target; such as `641x512` (`1.251953125`
+     *   ratio), `639x512` (`1.248046875` ratio), `640x513` (`1.247563353`
+     *   ratio) or `640x511` (`1.252446184` ratio). So whether you CAN hit your
+     *   EXACT desired non-`1.0` ratio or NOT depends 100% on your input file's
+     *   resolution! That's why we passthrough files that are already super
+     *   close to the desired ratio. Either way, such a tiny difference in
+     *   aspect ratio won't be visible to the eye, so if you are using this
+     *   "target ratio" feature for creating Instagram albums where all media
+     *   has the same aspect ratio, the final result WILL still look perfect.
+     *
+     * - "useRecommendedRatio" (bool): Whether to use the recommended aspect
+     *   ratio for your specific media type and target feed (such as using an
+     *   appropriate `9:16` portrait widescreen for stories). Some targets use
+     *   the recommended ratio by default, and others disable this by default.
+     *   Therefore, you do NOT need to set this option manually unless you have
+     *   a VERY special reason to do so! NOTE: This will ALWAYS be set to
+     *   `FALSE` if you're using the "forceAspectRatio" parameter!
+     *
+     * - "allowNewAspectDeviation" (bool): Whether to allow the new, final
+     *   aspect ratio (during processing) to deviate slightly from the MIN/MAX
+     *   limits. By setting this option to `TRUE`, you will tell our processing
+     *   to allow "slightly too high/slightly too low" final aspect ratios
+     *   (instead of throwing an exception) and to still permit the final
+     *   "closest-possible canvas" we've calculated anyway. You should NEVER
+     *   need to use this feature, but if you have manually configured extremely
+     *   narrow min/max aspect ratio parameters (which your input media CANNOT
+     *   be tweaked to fit perfectly within) then you MAY want to enable this.
+     *
+     * - "bgColor" (array) - Array with 3 color components `[R, G, B]`
+     *   (0-255/0x00-0xFF) for the background. Uses white if not set.
+     *
+     * - "blurredBorder" (bool) - Whether to use the media as a blurred border.
+     *   False if not set.
+     *
+     * - "operation" (int) - Operation to perform on the media (CROP or EXPAND).
+     *   Uses `self::CROP` if not set.
+     *
+     * - "tmpPath" (string) - Path to temp directory. Uses system temp location
+     *   or the class-default (`self::$defaultTmpPath`) if not set.
+     *
+     * - "debug" (bool) - Whether to output debugging info during calculation
+     *   steps.
+     *
+     * @param string $inputFile Path to an input file.
+     * @param array  $options   An associative array of optional parameters.

+/**
+ * Data Storage Interface.
+ *
+ * These methods must be implemented by all storage backends. All of their input
+ * and output validation is already done by the owning Settings class, so that
+ * backends can focus on dealing with basic, fully verified data (instead of
+ * writing and maintaining a bunch of boilerplate code to verify parameters).
+ *
+ * All functions in this file are listed in roughly the sequence they're called
+ * during normal operation. You can completely trust that they are called in a
+ * sane order and that you do not need to validate the call order.
+ *
+ * -- HOW TO STORE DATA: --
+ *
+ * The ONLY datatype we use for settings is STRINGS. You absolutely MUST store
+ * ALL data as strings. Do NOT attempt any "fancy" formats such as "database INT
+ * columns", because we will OFTEN be storing empty strings in all fields. Your
+ * storage backends MUST use STRING storage and MUST allow EMPTY strings.
+ *
+ * Data length varies, but it's a VERY bad idea for you to cap the length. We
+ * may need to store very long data someday. For example, the cookie data that
+ * we already store is usually around 2000 characters long.
+ *
+ * Furthermore, do NOT make ANY assumptions about what settings-"keys/columns"
+ * we will be storing. There is a list in StorageHandler::PERSISTENT_KEYS, but
+ * it will DEFINITELY change several times in the future. If you hardcode those
+ * columns, you will be in trouble in the future. Therefore, the absolute BEST
+ * encoding method is to use a SINGLE file/database column for the settings and
+ * to JSON-encode everything. And to use a SINGLE file/database column for the
+ * cookies and simply store our raw cookie string as-provided.
+ *
+ * -- MAJOR WARNING: --
+ *
+ * Backend developers are NOT allowed to violate ANY aspect of this interface
+ * specification. ANY exceptions thrown MUST be of the EXACT types listed, and
+ * ALL return values MUST be of the EXACT types listed. This means that YOU will
+ * have to handle ALL exceptions thrown by your particular backend solution, and
+ * re-wrapping them as the required exceptions if necessary. Otherwise you WILL
+ * BREAK all user applications that use your terrible Storage implementation.
+ *
+ * Just look at our existing Storage implementations to see correct code.

+<h1>Instagram-API Warning!</h1>
+<h2>Can I run this library via a website?</h2>
+<p>No. Don't do it. You cannot <em>safely</em> use this <em><strong>or any other</strong> 3rd party Instagram libraries</em> directly via a website!</p>
+<p>This library (and <em>all other</em> 3rd party reverse engineered Instagram libraries), is made for command line usage in a terminal by running the script like a program (such as <code>php yourscript.php</code>). We do <strong>not</strong> recommend running this library via a web browser! Because browsers will terminate the PHP process as soon as the user closes their connection to the page (closes the tab, or presses "Stop loading page"), which means that your script can terminate at any moment. This library is not a webpage! It is an Instagram for Android application emulator. It emulates an <strong>application</strong>. Not a webpage. You cannot just randomly kill this library in the middle of work! (You might kill it while it's writing to disk or calling some important APIs!)</p>
+<p>And furthermore, if it's used on a webpage then it must waste time logging in to Instagram every time the user refreshes the webpage, since each page load would start a new script (meaning "a new Instagram app emulator") from scratch. And there are also massive risks about concurrent access from multiple web requests to a single user account which can corrupt your settings-storage or cookies. So we really, <em>really</em> do not recommend running this library via a browser! It's a <em>very</em> bad idea!</p>
+<p>Instead, you should run your Instagram app emulator script as a permanent 24/7 process, and make it dump data to a database which your regular website reads from, or make some kind of permanent localhost daemon that can listen locally on the server and receive queries on a port (localhost queries from the main website's scripts), and then performing those queries via the API and responding to the website script with something like JSON or with serialized <code>src/Response/</code> objects, which the website script then transforms for final display to the user.</p>
+<p>You must also be sure that your permanent process periodically calls <code>login()</code> inside your 24/7 PHP process, to emulate the Instagram for Android application being closed/opened and refreshing itself (like a real user would do). Otherwise it will soon get banned or silently limited as a "detected bot" by Instagram due to never calling login. Preferably use the same refresh ranges we use by default, so that you refresh <code>login()</code> within a random range between every 30 minutes, or at max every 6 hours.</p>
+<p>So, to recap: Make your "Instagram application" part a permanent process, and then make your webpage interact with that permanent process or an intermediary database in some way. That's the <em>proper</em> architecture system if you want to use this library online! Imagine it like your website talking to a phone and telling its permanently running Instagram app to do things. <em>That's</em> the proper design and that's how you have to think about things.</p>
+<p>Never forget this fact: This library (and <em>all</em> other 3rd party libraries) is an Android application emulator. It is not a website and will <em>never</em> be able to become a website (because the Android application is not a website!). Therefore, we will <em>never</em> give support to anyone who decides to use the library directly inside a webpage. If you do that, it's <em>at your own risk</em>! It is a really terrible and unsupported idea!</p>

+# Changelog
+
+All notable changes to this project will be documented in this file, in reverse chronological order by release.
+
+## 1.0.1 - 2016-08-06
+
+### Added
+
+- Nothing.
+
+### Deprecated
+
+- Nothing.
+
+### Removed
+
+- Nothing.
+
+### Fixed
+
+- Updated all `@return self` annotation references in interfaces to use
+  `@return static`, which more closelly follows the semantics of the
+  specification.
+- Updated the `MessageInterface::getHeaders()` return annotation to use the
+  value `string[][]`, indicating the format is a nested array of strings.
+- Updated the `@link` annotation for `RequestInterface::withRequestTarget()`
+  to point to the correct section of RFC 7230.
+- Updated the `ServerRequestInterface::withUploadedFiles()` parameter annotation
+  to add the parameter name (`$uploadedFiles`).
+- Updated a `@throws` annotation for the `UploadedFileInterface::moveTo()`
+  method to correctly reference the method parameter (it was referencing an
+  incorrect parameter name previously).
+
+## 1.0.0 - 2016-05-18
+
+Initial stable release; reflects accepted PSR-7 specification.

+PSR Http Message
+================
+
+This repository holds all interfaces/classes/traits related to
+[PSR-7](http://www.php-fig.org/psr/psr-7/).
+
+Note that this is not a HTTP message implementation of its own. It is merely an
+interface that describes a HTTP message. See the specification for more details.
+
+Usage
+-----
+
+We'll certainly need some stuff in here.

+PSR Log
+=======
+
+This repository holds all interfaces/classes/traits related to
+[PSR-3](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md).
+
+Note that this is not a logger of its own. It is merely an interface that
+describes a logger. See the specification for more details.
+
+Installation
+------------
+
+```bash
+composer require psr/log
+```
+
+Usage
+-----
+
+If you need a logger, you can use the interface like this:
+
+```php
+<?php
+
+use Psr\Log\LoggerInterface;
+
+class Foo
+{
+    private $logger;
+
+    public function __construct(LoggerInterface $logger = null)
+    {
+        $this->logger = $logger;
+    }
+
+    public function doSomething()
+    {
+        if ($this->logger) {
+            $this->logger->info('Doing work');
+        }
+
+        // do something useful
+    }
+}
+```
+
+You can then pick one of the implementations of the interface to get a logger.
+
+If you want to implement the interface, you can require this package and
+implement `Psr\Log\LoggerInterface` in your code. Please read the
+[specification text](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md)
+for details.

+
+*   Improve API documentation and allow legacy HHVM to fail in Travis CI config.
+    (#34 and #36 by @clue)
+
+*   Prefix all global functions calls with \ to skip the look up and resolve process and go straight to the global function.
+    (#31 by @WyriHaximus)
+
+## 0.5.0 (2018-06-25)

+* Implemented (optional) Least Recently Used (LRU) cache algorithm for `ArrayCache`. 
+  (#26 by @clue)
+
+* Added support for cache expiration (TTL).
+  (#29 by @clue and @WyriHaximus)
+
+* Renamed `remove` to `delete` making it more in line with `PSR-16`.

+# Cache
+
+[![Build Status](https://travis-ci.org/reactphp/cache.svg?branch=master)](https://travis-ci.org/reactphp/cache)
+
+Async, [Promise](https://github.com/reactphp/promise)-based cache interface
+for [ReactPHP](https://reactphp.org/).
+
+The cache component provides a
+[Promise](https://github.com/reactphp/promise)-based
+[`CacheInterface`](#cacheinterface) and an in-memory [`ArrayCache`](#arraycache)
+implementation of that.
+This allows consumers to type hint against the interface and third parties to
+provide alternate implementations.
+This project is heavily inspired by
+[PSR-16: Common Interface for Caching Libraries](https://www.php-fig.org/psr/psr-16/),
+but uses an interface more suited for async, non-blocking applications.

+## Usage
+
+### CacheInterface
+
+The `CacheInterface` describes the main interface of this component.
+This allows consumers to type hint against the interface and third parties to
+provide alternate implementations.
+
+#### get()
+
+The `get(string $key, mixed $default = null): PromiseInterface<mixed>` method can be used to
+retrieve an item from the cache.
+
+This method will resolve with the cached value on success or with the
+given `$default` value when no item can be found or when an error occurs.
+Similarly, an expired cache item (once the time-to-live is expired) is
+considered a cache miss.
+
+```php
+$cache
+    ->get('foo')
+    ->then('var_dump');
+```
+
+This example fetches the value of the key `foo` and passes it to the
+`var_dump` function. You can use any of the composition provided by
+[promises](https://github.com/reactphp/promise).
+
+#### set()
+
+The `set(string $key, mixed $value, ?float $ttl = null): PromiseInterface<bool>` method can be used to
+store an item in the cache.
+
+This method will resolve with `true` on success or `false` when an error
+occurs. If the cache implementation has to go over the network to store
+it, it may take a while.
+
+The optional `$ttl` parameter sets the maximum time-to-live in seconds
+for this cache item. If this parameter is omitted (or `null`), the item
+will stay in the cache for as long as the underlying implementation
+supports. Trying to access an expired cache item results in a cache miss,
+see also [`get()`](#get).
+
+```php
+$cache->set('foo', 'bar', 60);
+```
+
+This example eventually sets the value of the key `foo` to `bar`. If it
+already exists, it is overridden.
+
+This interface does not enforce any particular TTL resolution, so special
+care may have to be taken if you rely on very high precision with
+millisecond accuracy or below. Cache implementations SHOULD work on a
+best effort basis and SHOULD provide at least second accuracy unless
+otherwise noted. Many existing cache implementations are known to provide
+microsecond or millisecond accuracy, but it's generally not recommended
+to rely on this high precision.
+
+This interface suggests that cache implementations SHOULD use a monotonic
+time source if available. Given that a monotonic time source is only
+available as of PHP 7.3 by default, cache implementations MAY fall back
+to using wall-clock time.
+While this does not affect many common use cases, this is an important
+distinction for programs that rely on a high time precision or on systems
+that are subject to discontinuous time adjustments (time jumps).
+This means that if you store a cache item with a TTL of 30s and then
+adjust your system time forward by 20s, the cache item SHOULD still
+expire in 30s.
+
+#### delete()
+
+The `delete(string $key): PromiseInterface<bool>` method can be used to
+delete an item from the cache.
+
+This method will resolve with `true` on success or `false` when an error
+occurs. When no item for `$key` is found in the cache, it also resolves
+to `true`. If the cache implementation has to go over the network to
+delete it, it may take a while.
+
+```php
+$cache->delete('foo');
+```
+
+This example eventually deletes the key `foo` from the cache. As with
+`set()`, this may not happen instantly and a promise is returned to
+provide guarantees whether or not the item has been removed from cache.
+
+#### getMultiple()
+
+The `getMultiple(string[] $keys, mixed $default = null): PromiseInterface<array>` method can be used to
+retrieve multiple cache items by their unique keys.
+
+This method will resolve with an array of cached values on success or with the
+given `$default` value when an item can not be found or when an error occurs.
+Similarly, an expired cache item (once the time-to-live is expired) is
+considered a cache miss.
+
+```php
+$cache->getMultiple(array('name', 'age'))->then(function (array $values) {
+    $name = $values['name'] ?? 'User';
+    $age = $values['age'] ?? 'n/a';
+
+    echo $name . ' is ' . $age . PHP_EOL;
+});
+```
+
+This example fetches the cache items for the `name` and `age` keys and
+prints some example output. You can use any of the composition provided
+by [promises](https://github.com/reactphp/promise).
+
+#### setMultiple()
+
+The `setMultiple(array $values, ?float $ttl = null): PromiseInterface<bool>` method can be used to
+persist a set of key => value pairs in the cache, with an optional TTL.
+
+This method will resolve with `true` on success or `false` when an error
+occurs. If the cache implementation has to go over the network to store
+it, it may take a while.
+
+The optional `$ttl` parameter sets the maximum time-to-live in seconds
+for these cache items. If this parameter is omitted (or `null`), these items
+will stay in the cache for as long as the underlying implementation
+supports. Trying to access an expired cache items results in a cache miss,
+see also [`getMultiple()`](#getmultiple).
+
+```php
+$cache->setMultiple(array('foo' => 1, 'bar' => 2), 60);
+```
+
+This example eventually sets the list of values - the key `foo` to `1` value 
+and the key `bar` to `2`. If some of the keys already exist, they are overridden.
+
+#### deleteMultiple()
+
+The `setMultiple(string[] $keys): PromiseInterface<bool>` method can be used to
+delete multiple cache items in a single operation.
+
+This method will resolve with `true` on success or `false` when an error
+occurs. When no items for `$keys` are found in the cache, it also resolves
+to `true`. If the cache implementation has to go over the network to
+delete it, it may take a while.
+
+```php
+$cache->deleteMultiple(array('foo', 'bar, 'baz'));
+```
+
+This example eventually deletes keys `foo`, `bar` and `baz` from the cache. 
+As with `setMultiple()`, this may not happen instantly and a promise is returned to
+provide guarantees whether or not the item has been removed from cache.
+
+#### clear()
+
+The `clear(): PromiseInterface<bool>` method can be used to
+wipe clean the entire cache.
+
+This method will resolve with `true` on success or `false` when an error
+occurs. If the cache implementation has to go over the network to
+delete it, it may take a while.
+
+```php
+$cache->clear();
+```
+
+This example eventually deletes all keys from the cache. As with `deleteMultiple()`, 
+this may not happen instantly and a promise is returned to provide guarantees 
+whether or not all the items have been removed from cache.
+
+#### has()
+
+The `has(string $key): PromiseInterface<bool>` method can be used to
+determine whether an item is present in the cache.
+
+This method will resolve with `true` on success or `false` when no item can be found 
+or when an error occurs. Similarly, an expired cache item (once the time-to-live 
+is expired) is considered a cache miss.
+
+```php
+$cache
+    ->has('foo')
+    ->then('var_dump');
+```
+
+This example checks if the value of the key `foo` is set in the cache and passes 
+the result to the `var_dump` function. You can use any of the composition provided by
+[promises](https://github.com/reactphp/promise).
+
+NOTE: It is recommended that has() is only to be used for cache warming type purposes
+and not to be used within your live applications operations for get/set, as this method
+is subject to a race condition where your has() will return true and immediately after,
+another script can remove it making the state of your app out of date.
+
+### ArrayCache
+
+The `ArrayCache` provides an in-memory implementation of the [`CacheInterface`](#cacheinterface).
+
+```php
+$cache = new ArrayCache();
+
+$cache->set('foo', 'bar');
+```
+
+Its constructor accepts an optional `?int $limit` parameter to limit the
+maximum number of entries to store in the LRU cache. If you add more
+entries to this instance, it will automatically take care of removing
+the one that was least recently used (LRU).
+
+For example, this snippet will overwrite the first value and only store
+the last two entries:
+
+```php
+$cache = new ArrayCache(2);
+
+$cache->set('foo', '1');
+$cache->set('bar', '2');
+$cache->set('baz', '3');
+```
+
+This cache implementation is known to rely on wall-clock time to schedule
+future cache expiration times when using any version before PHP 7.3,
+because a monotonic time source is only available as of PHP 7.3 (`hrtime()`).
+While this does not affect many common use cases, this is an important
+distinction for programs that rely on a high time precision or on systems
+that are subject to discontinuous time adjustments (time jumps).
+This means that if you store a cache item with a TTL of 30s on PHP < 7.3
+and then adjust your system time forward by 20s, the cache item may
+expire in 10s. See also [`set()`](#set) for more details.
+
+## Common usage
+
+### Fallback get
+
+A common use case of caches is to attempt fetching a cached value and as a
+fallback retrieve it from the original data source if not found. Here is an
+example of that:
+
+```php
+$cache
+    ->get('foo')
+    ->then(function ($result) {
+        if ($result === null) {
+            return getFooFromDb();
+        }
+        
+        return $result;
+    })
+    ->then('var_dump');
+```
+
+First an attempt is made to retrieve the value of `foo`. A callback function is 
+registered that will call `getFooFromDb` when the resulting value is null. 
+`getFooFromDb` is a function (can be any PHP callable) that will be called if the 
+key does not exist in the cache.
+
+`getFooFromDb` can handle the missing key by returning a promise for the
+actual value from the database (or any other data source). As a result, this
+chain will correctly fall back, and provide the value in both cases.
+
+### Fallback get and set
+
+To expand on the fallback get example, often you want to set the value on the
+cache after fetching it from the data source.
+
+```php
+$cache
+    ->get('foo')
+    ->then(function ($result) {
+        if ($result === null) {
+            return $this->getAndCacheFooFromDb();
+        }
+        
+        return $result;
+    })
+    ->then('var_dump');
+
+public function getAndCacheFooFromDb()
+{
+    return $this->db
+        ->get('foo')
+        ->then(array($this, 'cacheFooFromDb'));
+}
+
+public function cacheFooFromDb($foo)
+{
+    $this->cache->set('foo', $foo);
+
+    return $foo;
+}
+```
+
+By using chaining you can easily conditionally cache the value if it is
+fetched from the database.
+

+# Dns
+
+[![Build Status](https://travis-ci.org/reactphp/dns.svg?branch=master)](https://travis-ci.org/reactphp/dns)
+
+Async DNS resolver for [ReactPHP](https://reactphp.org/).
+
+The main point of the DNS component is to provide async DNS resolution.
+However, it is really a toolkit for working with DNS messages, and could
+easily be used to create a DNS server.

+
+## Basic usage
+
+The most basic usage is to just create a resolver through the resolver
+factory. All you need to give it is a nameserver, then you can start resolving
+names, baby!
+
+```php
+$loop = React\EventLoop\Factory::create();
+
+$config = React\Dns\Config\Config::loadSystemConfigBlocking();
+$server = $config->nameservers ? reset($config->nameservers) : '8.8.8.8';
+
+$factory = new React\Dns\Resolver\Factory();
+$dns = $factory->create($server, $loop);
+
+$dns->resolve('igor.io')->then(function ($ip) {
+    echo "Host: $ip\n";
+});
+
+$loop->run();
+```
+
+See also the [first example](examples).
+
+The `Config` class can be used to load the system default config. This is an
+operation that may access the filesystem and block. Ideally, this method should
+thus be executed only once before the loop starts and not repeatedly while it is
+running.
+Note that this class may return an *empty* configuration if the system config
+can not be loaded. As such, you'll likely want to apply a default nameserver
+as above if none can be found.
+
+> Note that the factory loads the hosts file from the filesystem once when
+  creating the resolver instance.
+  Ideally, this method should thus be executed only once before the loop starts
+  and not repeatedly while it is running.
+
+But there's more.
+
+## Caching
+
+You can cache results by configuring the resolver to use a `CachedExecutor`:
+
+```php
+$loop = React\EventLoop\Factory::create();
+
+$config = React\Dns\Config\Config::loadSystemConfigBlocking();
+$server = $config->nameservers ? reset($config->nameservers) : '8.8.8.8';
+
+$factory = new React\Dns\Resolver\Factory();
+$dns = $factory->createCached($server, $loop);
+
+$dns->resolve('igor.io')->then(function ($ip) {
+    echo "Host: $ip\n";
+});
+
+...
+
+$dns->resolve('igor.io')->then(function ($ip) {
+    echo "Host: $ip\n";
+});
+
+$loop->run();
+```
+
+If the first call returns before the second, only one query will be executed.
+The second result will be served from an in memory cache.
+This is particularly useful for long running scripts where the same hostnames
+have to be looked up multiple times.
+
+See also the [third example](examples).
+
+### Custom cache adapter
+
+By default, the above will use an in memory cache.
+
+You can also specify a custom cache implementing [`CacheInterface`](https://github.com/reactphp/cache) to handle the record cache instead:
+
+```php
+$cache = new React\Cache\ArrayCache();
+$loop = React\EventLoop\Factory::create();
+$factory = new React\Dns\Resolver\Factory();
+$dns = $factory->createCached('8.8.8.8', $loop, $cache);
+```
+
+See also the wiki for possible [cache implementations](https://github.com/reactphp/react/wiki/Users#cache-implementations).
+
+## Resolver
+
+### resolve()
+
+The `resolve(string $domain): PromiseInterface<string,Exception>` method can be used to
+resolve the given $domain name to a single IPv4 address (type `A` query).
+
+```php
+$resolver->resolve('reactphp.org')->then(function ($ip) {
+    echo 'IP for reactphp.org is ' . $ip . PHP_EOL;
+});
+```
+
+This is one of the main methods in this package. It sends a DNS query
+for the given $domain name to your DNS server and returns a single IP
+address on success.
+
+If the DNS server sends a DNS response message that contains more than
+one IP address for this query, it will randomly pick one of the IP
+addresses from the response. If you want the full list of IP addresses
+or want to send a different type of query, you should use the
+[`resolveAll()`](#resolveall) method instead.
+
+If the DNS server sends a DNS response message that indicates an error
+code, this method will reject with a `RecordNotFoundException`. Its
+message and code can be used to check for the response code.
+
+If the DNS communication fails and the server does not respond with a
+valid response message, this message will reject with an `Exception`.
+
+Pending DNS queries can be cancelled by cancelling its pending promise like so:
+
+```php
+$promise = $resolver->resolve('reactphp.org');
+
+$promise->cancel();
+```
+
+### resolveAll()
+
+The `resolveAll(string $host, int $type): PromiseInterface<array,Exception>` method can be used to
+resolve all record values for the given $domain name and query $type.
+
+```php
+$resolver->resolveAll('reactphp.org', Message::TYPE_A)->then(function ($ips) {
+    echo 'IPv4 addresses for reactphp.org ' . implode(', ', $ips) . PHP_EOL;
+});
+
+$resolver->resolveAll('reactphp.org', Message::TYPE_AAAA)->then(function ($ips) {
+    echo 'IPv6 addresses for reactphp.org ' . implode(', ', $ips) . PHP_EOL;
+});
+```
+
+This is one of the main methods in this package. It sends a DNS query
+for the given $domain name to your DNS server and returns a list with all
+record values on success.
+
+If the DNS server sends a DNS response message that contains one or more
+records for this query, it will return a list with all record values
+from the response. You can use the `Message::TYPE_*` constants to control
+which type of query will be sent. Note that this method always returns a
+list of record values, but each record value type depends on the query
+type. For example, it returns the IPv4 addresses for type `A` queries,
+the IPv6 addresses for type `AAAA` queries, the hostname for type `NS`,
+`CNAME` and `PTR` queries and structured data for other queries. See also
+the `Record` documentation for more details.
+
+If the DNS server sends a DNS response message that indicates an error
+code, this method will reject with a `RecordNotFoundException`. Its
+message and code can be used to check for the response code.
+
+If the DNS communication fails and the server does not respond with a
+valid response message, this message will reject with an `Exception`.
+
+Pending DNS queries can be cancelled by cancelling its pending promise like so:
+
+```php
+$promise = $resolver->resolveAll('reactphp.org', Message::TYPE_AAAA);
+
+$promise->cancel();
+```
+
+## Advanced Usage
+
+### UdpTransportExecutor
+
+The `UdpTransportExecutor` can be used to
+send DNS queries over a UDP transport.
+
+This is the main class that sends a DNS query to your DNS server and is used
+internally by the `Resolver` for the actual message transport.
+
+For more advanced usages one can utilize this class directly.
+The following example looks up the `IPv6` address for `igor.io`.
+
+```php
+$loop = Factory::create();
+$executor = new UdpTransportExecutor($loop);
+
+$executor->query(
+    '8.8.8.8:53', 
+    new Query($name, Message::TYPE_AAAA, Message::CLASS_IN)
+)->then(function (Message $message) {
+    foreach ($message->answers as $answer) {
+        echo 'IPv6: ' . $answer->data . PHP_EOL;
+    }
+}, 'printf');
+
+$loop->run();
+```
+
+See also the [fourth example](examples).
+
+Note that this executor does not implement a timeout, so you will very likely
+want to use this in combination with a `TimeoutExecutor` like this:
+
+```php
+$executor = new TimeoutExecutor(
+    new UdpTransportExecutor($loop),
+    3.0,
+    $loop
+);
+```
+
+Also note that this executor uses an unreliable UDP transport and that it
+does not implement any retry logic, so you will likely want to use this in
+combination with a `RetryExecutor` like this:
+
+```php
+$executor = new RetryExecutor(
+    new TimeoutExecutor(
+        new UdpTransportExecutor($loop),
+        3.0,
+        $loop
+    )
+);
+```
+
+Note that this executor is entirely async and as such allows you to execute
+any number of queries concurrently. You should probably limit the number of
+concurrent queries in your application or you're very likely going to face
+rate limitations and bans on the resolver end. For many common applications,
+you may want to avoid sending the same query multiple times when the first
+one is still pending, so you will likely want to use this in combination with
+a `CoopExecutor` like this:
+
+```php
+$executor = new CoopExecutor(
+    new RetryExecutor(
+        new TimeoutExecutor(
+            new UdpTransportExecutor($loop),
+            3.0,
+            $loop
+        )
+    )
+);
+```
+
+> Internally, this class uses PHP's UDP sockets and does not take advantage
+  of [react/datagram](https://github.com/reactphp/datagram) purely for
+  organizational reasons to avoid a cyclic dependency between the two
+  packages. Higher-level components should take advantage of the Datagram
+  component instead of reimplementing this socket logic from scratch.
+
+### HostsFileExecutor
+
+Note that the above `UdpTransportExecutor` class always performs an actual DNS query.
+If you also want to take entries from your hosts file into account, you may
+use this code:
+
+```php
+$hosts = \React\Dns\Config\HostsFile::loadFromPathBlocking();
+
+$executor = new UdpTransportExecutor($loop);
+$executor = new HostsFileExecutor($hosts, $executor);
+
+$executor->query(
+    '8.8.8.8:53', 
+    new Query('localhost', Message::TYPE_A, Message::CLASS_IN)
+);
+```
+
+## Install
+
+The recommended way to install this library is [through Composer](https://getcomposer.org).
+[New to Composer?](https://getcomposer.org/doc/00-intro.md)
+
+This will install the latest supported version:
+
+```bash
+$ composer require react/dns:^0.4.19
+```
+
+See also the [CHANGELOG](CHANGELOG.md) for details about version upgrades.
+
+This project aims to run on any platform and thus does not require any PHP
+extensions and supports running on legacy PHP 5.3 through current PHP 7+ and
+HHVM.
+It's *highly recommended to use PHP 7+* for this project.
+
+## Tests
+
+To run the test suite, you first need to clone this repo and then install all
+dependencies [through Composer](https://getcomposer.org):
+
+```bash
+$ composer install
+```
+
+To run the test suite, go to the project root and run:
+
+```bash
+$ php vendor/bin/phpunit
+```
+
+The test suite also contains a number of functional integration tests that rely
+on a stable internet connection.

+     * this library will try to express this in a way that can be consumed
+     * easily without having to worry about DNS internals and its binary transport:
+     *
+     * - A:
+     *   IPv4 address string, for example "192.168.1.1".
+     * - AAAA:
+     *   IPv6 address string, for example "::1".
+     * - CNAME / PTR / NS:
+     *   The hostname without trailing dot, for example "reactphp.org".
+     * - TXT:
+     *   List of string values, for example `["v=spf1 include:example.com"]`.
+     *   This is commonly a list with only a single string value, but this
+     *   technically allows multiple strings (0-255 bytes each) in a single
+     *   record. This is rarely used and depending on application you may want
+     *   to join these together or handle them separately. Each string can
+     *   transport any binary data, its character encoding is not defined (often
+     *   ASCII/UTF-8 in practice). [RFC 1464](https://tools.ietf.org/html/rfc1464)
+     *   suggests using key-value pairs such as `["name=test","version=1"]`, but
+     *   interpretation of this is not enforced and left up to consumers of this
+     *   library (used for DNS-SD/Zeroconf and others).
+     * - MX:
+     *   Mail server priority (UINT16) and target hostname without trailing dot,
+     *   for example `{"priority":10,"target":"mx.example.com"}`.
+     *   The payload data uses an associative array with fixed keys "priority"
+     *   (also commonly referred to as weight or preference) and "target" (also
+     *   referred to as exchange). If a response message contains multiple
+     *   records of this type, targets should be sorted by priority (lowest
+     *   first) - this is left up to consumers of this library (used for SMTP).
+     * - SRV:
+     *   Service priority (UINT16), service weight (UINT16), service port (UINT16)
+     *   and target hostname without trailing dot, for example
+     *   `{"priority":10,"weight":50,"port":8080,"target":"example.com"}`.
+     *   The payload data uses an associative array with fixed keys "priority",
+     *   "weight", "port" and "target" (also referred to as name).
+     *   The target may be an empty host name string if the service is decidedly
+     *   not available. If a response message contains multiple records of this
+     *   type, targets should be sorted by priority (lowest first) and selected
+     *   randomly according to their weight - this is left up to consumers of
+     *   this library, see also [RFC 2782](https://tools.ietf.org/html/rfc2782)
+     *   for more details.
+     * - SOA:
+     *   Includes master hostname without trailing dot, responsible person email
+     *   as hostname without trailing dot and serial, refresh, retry, expire and
+     *   minimum times in seconds (UINT32 each), for example:
+     *   `{"mname":"ns.example.com","rname":"hostmaster.example.com","serial":
+     *   2018082601,"refresh":3600,"retry":1800,"expire":60000,"minimum":3600}`.
+     * - Any other unknown type:
+     *   An opaque binary string containing the RDATA as transported in the DNS
+     *   record. For forwards compatibility, you should not rely on this format
+     *   for unknown types. Future versions may add support for new types and
+     *   this may then parse the payload data appropriately - this will not be

+ *
+ * Wraps an existing `ExecutorInterface` to keep tracking of pending queries
+ * and only starts a new query when the same query is not already pending. Once

+ * promises awaiting the same query.
+ *
+ * This means it will not limit concurrency for queries that differ, for example
+ * when sending many queries for different host names or types.
+ *
+ * This is useful because all executors are entirely async and as such allow you
+ * to execute any number of queries concurrently. You should probably limit the
+ * number of concurrent queries in your application or you're very likely going
+ * to face rate limitations and bans on the resolver end. For many common
+ * applications, you may want to avoid sending the same query multiple times
+ * when the first one is still pending, so you will likely want to use this in
+ * combination with some other executor like this:
+ *
+ * ```php
+ * $executor = new CoopExecutor(
+ *     new RetryExecutor(
+ *         new TimeoutExecutor(

+/**
+ * Send DNS queries over a UDP transport.
+ *
+ * This is the main class that sends a DNS query to your DNS server and is used
+ * internally by the `Resolver` for the actual message transport.
+ *
+ * For more advanced usages one can utilize this class directly.
+ * The following example looks up the `IPv6` address for `igor.io`.
+ *
+ * ```php
+ * $loop = Factory::create();
+ * $executor = new UdpTransportExecutor($loop);
+ *
+ * $executor->query(
+ *     '8.8.8.8:53',
+ *     new Query($name, Message::TYPE_AAAA, Message::CLASS_IN)
+ * )->then(function (Message $message) {
+ *     foreach ($message->answers as $answer) {
+ *         echo 'IPv6: ' . $answer->data . PHP_EOL;
+ *     }
+ * }, 'printf');
+ *
+ * $loop->run();
+ * ```
+ *
+ * See also the [fourth example](examples).
+ *
+ * Note that this executor does not implement a timeout, so you will very likely
+ * want to use this in combination with a `TimeoutExecutor` like this:
+ *
+ * ```php
+ * $executor = new TimeoutExecutor(
+ *     new UdpTransportExecutor($loop),
+ *     3.0,
+ *     $loop
+ * );
+ * ```
+ *
+ * Also note that this executor uses an unreliable UDP transport and that it
+ * does not implement any retry logic, so you will likely want to use this in
+ * combination with a `RetryExecutor` like this:
+ *
+ * ```php
+ * $executor = new RetryExecutor(
+ *     new TimeoutExecutor(
+ *         new UdpTransportExecutor($loop),
+ *         3.0,
+ *         $loop
+ *     )
+ * );
+ * ```
+ *
+ * Note that this executor is entirely async and as such allows you to execute
+ * any number of queries concurrently. You should probably limit the number of
+ * concurrent queries in your application or you're very likely going to face
+ * rate limitations and bans on the resolver end. For many common applications,
+ * you may want to avoid sending the same query multiple times when the first
+ * one is still pending, so you will likely want to use this in combination with
+ * a `CoopExecutor` like this:
+ *
+ * ```php
+ * $executor = new CoopExecutor(
+ *     new RetryExecutor(
+ *         new TimeoutExecutor(
+ *             new UdpTransportExecutor($loop),
+ *             3.0,
+ *             $loop
+ *         )
+ *     )
+ * );
+ * ```
+ *
+ * > Internally, this class uses PHP's UDP sockets and does not take advantage
+ *   of [react/datagram](https://github.com/reactphp/datagram) purely for
+ *   organizational reasons to avoid a cyclic dependency between the two
+ *   packages. Higher-level components should take advantage of the Datagram
+ *   component instead of reimplementing this socket logic from scratch.

+# EventLoop Component
+
+[![Build Status](https://travis-ci.org/reactphp/event-loop.svg?branch=master)](https://travis-ci.org/reactphp/event-loop)
+[![Code Climate](https://codeclimate.com/github/reactphp/event-loop/badges/gpa.svg)](https://codeclimate.com/github/reactphp/event-loop)
+
+Event loop abstraction layer that libraries can use for evented I/O.
+
+In order for async based libraries to be interoperable, they need to use the
+same event loop. This component provides a common `LoopInterface` that any
+library can target. This allows them to be used in the same loop, with one
+single `run()` call that is controlled by the user.
+
+**Table of Contents**
+
+* [Quickstart example](#quickstart-example)
+* [Usage](#usage)
+* [Loop implementations](#loop-implementations)
+* [Install](#install)
+* [Tests](#tests)
+* [License](#license)
+
+## Quickstart example
+
+Here is an async HTTP server built with just the event loop.
+
+```php
+$loop = React\EventLoop\Factory::create();
+
+$server = stream_socket_server('tcp://127.0.0.1:8080');
+stream_set_blocking($server, 0);
+
+$loop->addReadStream($server, function ($server) use ($loop) {
+    $conn = stream_socket_accept($server);
+    $data = "HTTP/1.1 200 OK\r\nContent-Length: 3\r\n\r\nHi\n";
+    $loop->addWriteStream($conn, function ($conn) use (&$data, $loop) {
+        $written = fwrite($conn, $data);
+        if ($written === strlen($data)) {
+            fclose($conn);
+            $loop->removeStream($conn);
+        } else {
+            $data = substr($data, $written);
+        }
+    });
+});
+
+$loop->addPeriodicTimer(5, function () {
+    $memory = memory_get_usage() / 1024;
+    $formatted = number_format($memory, 3).'K';
+    echo "Current memory usage: {$formatted}\n";
+});
+
+$loop->run();
+```
+
+## Usage
+
+Typical applications use a single event loop which is created at the beginning
+and run at the end of the program.
+
+```php
+// [1]
+$loop = React\EventLoop\Factory::create();
+
+// [2]
+$loop->addPeriodicTimer(1, function () {
+    echo "Tick\n";
+});
+
+$stream = new React\Stream\ReadableResourceStream(
+    fopen('file.txt', 'r'),
+    $loop
+);
+
+// [3]
+$loop->run();
+```
+
+1. The loop instance is created at the beginning of the program. A convenience
+   factory `React\EventLoop\Factory::create()` is provided by this library which
+   picks the best available [loop implementation](#loop-implementations).
+2. The loop instance is used directly or passed to library and application code.
+   In this example, a periodic timer is registered with the event loop which
+   simply outputs `Tick` every second and a
+   [readable stream](https://github.com/reactphp/stream#readableresourcestream)
+   is created by using ReactPHP's
+   [stream component](https://github.com/reactphp/stream) for demonstration
+   purposes.
+3. The loop is run with a single `$loop->run()` call at the end of the program.
+
+## Loop implementations
+
+In addition to the interface there are the following implementations provided:
+
+* `StreamSelectLoop`: This is the only implementation which works out of the
+  box with PHP. It does a simple `select` system call. It's not the most
+  performant of loops, but still does the job quite well.
+
+* `LibEventLoop`: This uses the `libevent` pecl extension. `libevent` itself
+  supports a number of system-specific backends (epoll, kqueue).
+
+* `LibEvLoop`: This uses the `libev` pecl extension
+  ([github](https://github.com/m4rw3r/php-libev)). It supports the same
+  backends as libevent.
+
+* `ExtEventLoop`: This uses the `event` pecl extension. It supports the same
+  backends as libevent.
+
+All of the loops support these features:
+
+* File descriptor polling
+* One-off timers
+* Periodic timers
+* Deferred execution of callbacks
+
+## Install
+
+The recommended way to install this library is [through Composer](http://getcomposer.org).
+[New to Composer?](http://getcomposer.org/doc/00-intro.md)
+
+This will install the latest supported version:
+
+```bash
+$ composer require react/event-loop
+```
+
+## Tests
+
+To run the test suite, you first need to clone this repo and then install all
+dependencies [through Composer](http://getcomposer.org):
+
+```bash
+$ composer install
+```
+
+To run the test suite, go to the project root and run:
+
+```bash
+$ php vendor/bin/phpunit
+```

+
+## Usage
+
+This lightweight library consists only of a few simple functions.
+All functions reside under the `React\Promise\Timer` namespace.
+
+The below examples assume you use an import statement similar to this:
+
+```php
+use React\Promise\Timer;
+
+Timer\timeout(…);
+```
+
+Alternatively, you can also refer to them with their fully-qualified name:
+
+```php
+\React\Promise\Timer\timeout(…);
+```
+
+### timeout()
+
+The `timeout(PromiseInterface $promise, $time, LoopInterface $loop)` function
+can be used to *cancel* operations that take *too long*.
+You need to pass in an input `$promise` that represents a pending operation and timeout parameters.
+It returns a new `Promise` with the following resolution behavior:
+
+* If the input `$promise` resolves before `$time` seconds, resolve the resulting promise with its fulfillment value.
+* If the input `$promise` rejects before `$time` seconds, reject the resulting promise with its rejection value.
+* If the input `$promise` does not settle before `$time` seconds, *cancel* the operation and reject the resulting promise with a [`TimeoutException`](#timeoutexception).
+
+Internally, the given `$time` value will be used to start a timer that will
+*cancel* the pending operation once it triggers.
+This implies that if you pass a really small (or negative) value, it will still
+start a timer and will thus trigger at the earliest possible time in the future.
+
+If the input `$promise` is already settled, then the resulting promise will
+resolve or reject immediately without starting a timer at all.
+
+A common use case for handling only resolved values looks like this:
+
+```php
+$promise = accessSomeRemoteResource();
+Timer\timeout($promise, 10.0, $loop)->then(function ($value) {
+    // the operation finished within 10.0 seconds
+});
+```
+
+A more complete example could look like this:
+
+```php
+$promise = accessSomeRemoteResource();
+Timer\timeout($promise, 10.0, $loop)->then(
+    function ($value) {
+        // the operation finished within 10.0 seconds
+    },
+    function ($error) {
+        if ($error instanceof Timer\TimeoutException) {
+            // the operation has failed due to a timeout
+        } else {
+            // the input operation has failed due to some other error
+        }
+    }
+);
+```
+
+Or if you're using [react/promise v2.2.0](https://github.com/reactphp/promise) or up:
+
+```php
+Timer\timeout($promise, 10.0, $loop)
+    ->then(function ($value) {
+        // the operation finished within 10.0 seconds
+    })
+    ->otherwise(function (Timer\TimeoutException $error) {
+        // the operation has failed due to a timeout
+    })
+    ->otherwise(function ($error) {
+        // the input operation has failed due to some other error
+    })
+;
+```
+
+#### Timeout cancellation
+
+As discussed above, the [`timeout()`](#timeout) function will *cancel* the
+underlying operation if it takes *too long*.
+This means that you can be sure the resulting promise will then be rejected
+with a [`TimeoutException`](#timeoutexception).
+
+However, what happens to the underlying input `$promise` is a bit more tricky:
+Once the timer fires, we will try to call
+[`$promise->cancel()`](https://github.com/reactphp/promise#cancellablepromiseinterfacecancel)
+on the input `$promise` which in turn invokes its [cancellation handler](#cancellation-handler).
+
+This means that it's actually up the input `$promise` to handle
+[cancellation support](https://github.com/reactphp/promise#cancellablepromiseinterface).
+
+* A common use case involves cleaning up any resources like open network sockets or
+  file handles or terminating external processes or timers.
+
+* If the given input `$promise` does not support cancellation, then this is a NO-OP.
+  This means that while the resulting promise will still be rejected, the underlying
+  input `$promise` may still be pending and can hence continue consuming resources.
+
+See the following chapter for more details on the cancellation handler.
+
+#### Cancellation handler
+
+For example, an implementation for the above operation could look like this:
+
+```php
+function accessSomeRemoteResource()
+{
+    return new Promise(
+        function ($resolve, $reject) use (&$socket) {
+            // this will be called once the promise is created
+            // a common use case involves opening any resources and eventually resolving
+            $socket = createSocket();
+            $socket->on('data', function ($data) use ($resolve) {
+                $resolve($data);
+            });
+        },
+        function ($resolve, $reject) use (&$socket) {
+            // this will be called once calling `cancel()` on this promise
+            // a common use case involves cleaning any resources and then rejecting
+            $socket->close();
+            $reject(new \RuntimeException('Operation cancelled'));
+        }
+    );
+}
+```
+
+In this example, calling `$promise->cancel()` will invoke the registered cancellation
+handler which then closes the network socket and rejects the `Promise` instance.
+
+If no cancellation handler is passed to the `Promise` constructor, then invoking
+its `cancel()` method it is effectively a NO-OP.
+This means that it may still be pending and can hence continue consuming resources.
+
+For more details on the promise cancellation, please refer to the
+[Promise documentation](https://github.com/reactphp/promise#cancellablepromiseinterface).
+
+#### Input cancellation
+
+Irrespective of the timeout handling, you can also explicitly `cancel()` the
+input `$promise` at any time.
+This means that the `timeout()` handling does not affect cancellation of the
+input `$promise`, as demonstrated in the following example:
+
+```php
+$promise = accessSomeRemoteResource();
+$timeout = Timer\timeout($promise, 10.0, $loop);
+
+$promise->cancel();
+```
+
+The registered [cancellation handler](#cancellation-handler) is responsible for
+handling the `cancel()` call:
+
+* A described above, a common use involves resource cleanup and will then *reject*
+  the `Promise`.
+  If the input `$promise` is being rejected, then the timeout will be aborted
+  and the resulting promise will also be rejected.
+* If the input `$promise` is still pending, then the timout will continue
+  running until the timer expires.
+  The same happens if the input `$promise` does not register a
+  [cancellation handler](#cancellation-handler). 
+
+#### Output cancellation
+
+Similarily, you can also explicitly `cancel()` the resulting promise like this:
+
+```php
+$promise = accessSomeRemoteResource();
+$timeout = Timer\timeout($promise, 10.0, $loop);
+
+$timeout->cancel();
+```
+
+Note how this looks very similar to the above [input cancellation](#input-cancellation)
+example. Accordingly, it also behaves very similar.
+
+Calling `cancel()` on the resulting promise will merely try
+to `cancel()` the input `$promise`.
+This means that we do not take over responsibility of the outcome and it's
+entirely up to the input `$promise` to handle cancellation support.
+
+The registered [cancellation handler](#cancellation-handler) is responsible for
+handling the `cancel()` call:
+
+* As described above, a common use involves resource cleanup and will then *reject*
+  the `Promise`.
+  If the input `$promise` is being rejected, then the timeout will be aborted
+  and the resulting promise will also be rejected.
+* If the input `$promise` is still pending, then the timout will continue
+  running until the timer expires.
+  The same happens if the input `$promise` does not register a
+  [cancellation handler](#cancellation-handler). 
+
+To re-iterate, note that calling `cancel()` on the resulting promise will merely
+try to cancel the input `$promise` only.
+It is then up to the cancellation handler of the input promise to settle the promise.
+If the input promise is still pending when the timeout occurs, then the normal
+[timeout cancellation](#timeout-cancellation) handling will trigger, effectively rejecting
+the output promise with a [`TimeoutException`](#timeoutexception).
+
+This is done for consistency with the [timeout cancellation](#timeout-cancellation)
+handling and also because it is assumed this is often used like this:
+
+```php
+$timeout = Timer\timeout(accessSomeRemoteResource(), 10.0, $loop);
+
+$timeout->cancel();
+```
+
+As described above, this example works as expected and cleans up any resources
+allocated for the input `$promise`.
+
+Note that if the given input `$promise` does not support cancellation, then this
+is a NO-OP.
+This means that while the resulting promise will still be rejected after the
+timeout, the underlying input `$promise` may still be pending and can hence
+continue consuming resources.
+
+#### Collections
+
+If you want to wait for multiple promises to resolve, you can use the normal promise primitives like this:
+
+```php
+$promises = array(
+    accessSomeRemoteResource(),
+    accessSomeRemoteResource(),
+    accessSomeRemoteResource()
+);
+
+$promise = \React\Promise\all($promises);
+
+Timer\timeout($promise, 10, $loop)->then(function ($values) {
+    // *all* promises resolved
+});
+```
+
+The applies to all promise collection primitives alike, i.e. `all()`, `race()`, `any()`, `some()` etc.
+
+For more details on the promise primitives, please refer to the
+[Promise documentation](https://github.com/reactphp/promise#functions).
+
+### resolve()
+
+The `resolve($time, LoopInterface $loop)` function can be used to create a new Promise that
+resolves in `$time` seconds with the `$time` as the fulfillment value.
+
+```php
+Timer\resolve(1.5, $loop)->then(function ($time) {
+    echo 'Thanks for waiting ' . $time . ' seconds' . PHP_EOL;
+});
+```
+
+Internally, the given `$time` value will be used to start a timer that will
+resolve the promise once it triggers.
+This implies that if you pass a really small (or negative) value, it will still
+start a timer and will thus trigger at the earliest possible time in the future.
+
+#### Resolve cancellation
+
+You can explicitly `cancel()` the resulting timer promise at any time:
+
+```php
+$timer = Timer\resolve(2.0, $loop);
+
+$timer->cancel();
+```
+
+This will abort the timer and *reject* with a `RuntimeException`.
+
+### reject()
+
+The `reject($time, LoopInterface $loop)` function can be used to create a new Promise
+which rejects in `$time` seconds with a `TimeoutException`.
+
+```php
+Timer\reject(2.0, $loop)->then(null, function (TimeoutException $e) {
+    echo 'Rejected after ' . $e->getTimeout() . ' seconds ' . PHP_EOL;
+});
+```
+
+Internally, the given `$time` value will be used to start a timer that will
+reject the promise once it triggers.
+This implies that if you pass a really small (or negative) value, it will still
+start a timer and will thus trigger at the earliest possible time in the future.
+
+This function complements the [`resolve()`](#resolve) function
+and can be used as a basic building block for higher-level promise consumers.
+
+#### Reject cancellation
+
+You can explicitly `cancel()` the resulting timer promise at any time:
+
+```php
+$timer = Timer\reject(2.0, $loop);
+
+$timer->cancel();
+```
+
+This will abort the timer and *reject* with a `RuntimeException`.
+
+### TimeoutException
+
+The `TimeoutException` extends PHP's built-in `RuntimeException`.
+
+The `getTimeout()` method can be used to get the timeout value in seconds.

+CHANGELOG for 2.x
+=================
+
+* 2.7.1 (2018-01-07)
+
+    *   Fix: file_exists warning when resolving with long strings.
+        (#130 by @sbesselsen)
+    *   Improve performance by prefixing all global functions calls with \ to skip the look up and resolve process and go straight to the global function.
+        (#133 by @WyriHaximus)
+
+* 2.7.0 (2018-06-13)
+
+    *   Feature: Improve memory consumption for pending promises by using static internal callbacks without binding to self.
+        (#124 by @clue)
+
+* 2.6.0 (2018-06-11)
+
+    *   Feature: Significantly improve memory consumption and performance by only passing resolver args
+        to resolver and canceller if callback requires them. Also use static callbacks without
+        binding to promise, clean up canceller function reference when they are no longer
+        needed and hide resolver and canceller references from call stack on PHP 7+.
+        (#113, #115, #116, #117, #118, #119 and #123 by @clue)
+
+        These changes combined mean that rejecting promises with an `Exception` should
+        no longer cause any internal circular references which could cause some unexpected
+        memory growth in previous versions. By explicitly avoiding and explicitly
+        cleaning up said references, we can avoid relying on PHP's circular garbage collector
+        to kick in which significantly improves performance when rejecting many promises.
+
+    *   Mark legacy progress support / notification API as deprecated
+        (#112 by @clue)
+

+                           $promise->cancel();
+                       }
+                   }
+              });

+    * Add new `always()` method (part of the `ExtendedPromiseInterface`).
+    * Add new `progress()` method (part of the `ExtendedPromiseInterface`).
+    * Rename `Deferred::progress` to `Deferred::notify` to avoid confusion with
+      `ExtendedPromiseInterface::progress` (a `Deferred::progress` alias is

+    * `resolve()` now always returns a `ExtendedPromiseInterface`.
+
+* 2.1.0 (2014-10-15)
+
+    * Introduce new `CancellablePromiseInterface` implemented by all promises.
+    * Add new `cancel()` method (part of the `CancellablePromiseInterface`).
+
+* 2.0.0 (2013-12-10)

+
+    * Add standalone Promise class.
+    * Add new `race()` function.
+    * BC break: Bump minimum PHP version to PHP 5.4.
+    * BC break: Remove `ResolverInterface` and `PromiseInterface` from 
+      `Deferred`.
+    * BC break: Change signature of `PromiseInterface`.
+    * BC break: Remove `When` and `Util` classes and move static methods to
+      functions.
+    * BC break: `FulfilledPromise` and `RejectedPromise` now throw an exception
+      when initialized with a promise instead of a value/reason.
+    * BC break: `Deferred::resolve()` and `Deferred::reject()` no longer return
+      a promise.

+Introduction
+------------
+
+Promise is a library implementing
+[CommonJS Promises/A](http://wiki.commonjs.org/wiki/Promises/A) for PHP.
+
+It also provides several other useful promise-related concepts, such as joining
+multiple promises and mapping and reducing collections of promises.
+
+If you've never heard about promises before,
+[read this first](https://gist.github.com/3889970).
+
+Concepts
+--------
+
+### Deferred
+
+A **Deferred** represents a computation or unit of work that may not have
+completed yet. Typically (but not always), that computation will be something
+that executes asynchronously and completes at some point in the future.
+
+### Promise
+
+While a deferred represents the computation itself, a **Promise** represents
+the result of that computation. Thus, each deferred has a promise that acts as
+a placeholder for its actual result.
+
+API
+---
+
+### Deferred
+
+A deferred represents an operation whose resolution is pending. It has separate
+promise and resolver parts.
+
+```php
+$deferred = new React\Promise\Deferred();
+
+$promise = $deferred->promise();
+
+$deferred->resolve(mixed $value = null);
+$deferred->reject(mixed $reason = null);
+$deferred->notify(mixed $update = null);
+```
+
+The `promise` method returns the promise of the deferred.
+
+The `resolve` and `reject` methods control the state of the deferred.
+
+The deprecated `notify` method is for progress notification.
+
+The constructor of the `Deferred` accepts an optional `$canceller` argument.
+See [Promise](#promise-2) for more information.
+
+#### Deferred::promise()
+
+```php
+$promise = $deferred->promise();
+```
+
+Returns the promise of the deferred, which you can hand out to others while
+keeping the authority to modify its state to yourself.
+
+#### Deferred::resolve()
+
+```php
+$deferred->resolve(mixed $value = null);
+```
+
+Resolves the promise returned by `promise()`. All consumers are notified by
+having `$onFulfilled` (which they registered via `$promise->then()`) called with
+`$value`.
+
+If `$value` itself is a promise, the promise will transition to the state of
+this promise once it is resolved.
+
+#### Deferred::reject()
+
+```php
+$deferred->reject(mixed $reason = null);
+```
+
+Rejects the promise returned by `promise()`, signalling that the deferred's
+computation failed.
+All consumers are notified by having `$onRejected` (which they registered via
+`$promise->then()`) called with `$reason`.
+
+If `$reason` itself is a promise, the promise will be rejected with the outcome
+of this promise regardless whether it fulfills or rejects.
+
+#### Deferred::notify()
+
+> Deprecated in v2.6.0: Progress support is deprecated and should not be used anymore.
+
+```php
+$deferred->notify(mixed $update = null);
+```
+
+Triggers progress notifications, to indicate to consumers that the computation
+is making progress toward its result.
+
+All consumers are notified by having `$onProgress` (which they registered via
+`$promise->then()`) called with `$update`.
+
+### PromiseInterface
+
+The promise interface provides the common interface for all promise
+implementations.
+
+A promise represents an eventual outcome, which is either fulfillment (success)
+and an associated value, or rejection (failure) and an associated reason.
+
+Once in the fulfilled or rejected state, a promise becomes immutable.
+Neither its state nor its result (or error) can be modified.
+
+#### Implementations
+
+* [Promise](#promise-2)
+* [FulfilledPromise](#fulfilledpromise)
+* [RejectedPromise](#rejectedpromise)
+* [LazyPromise](#lazypromise)
+
+#### PromiseInterface::then()
+
+```php
+$transformedPromise = $promise->then(callable $onFulfilled = null, callable $onRejected = null, callable $onProgress = null);
+```
+
+Transforms a promise's value by applying a function to the promise's fulfillment
+or rejection value. Returns a new promise for the transformed result.
+
+The `then()` method registers new fulfilled, rejection and progress handlers
+with a promise (all parameters are optional):
+
+  * `$onFulfilled` will be invoked once the promise is fulfilled and passed
+    the result as the first argument.
+  * `$onRejected` will be invoked once the promise is rejected and passed the
+    reason as the first argument.
+  * `$onProgress` (deprecated) will be invoked whenever the producer of the promise
+    triggers progress notifications and passed a single argument (whatever it
+    wants) to indicate progress.
+
+It returns a new promise that will fulfill with the return value of either
+`$onFulfilled` or `$onRejected`, whichever is called, or will reject with
+the thrown exception if either throws.
+
+A promise makes the following guarantees about handlers registered in
+the same call to `then()`:
+
+  1. Only one of `$onFulfilled` or `$onRejected` will be called,
+     never both.
+  2. `$onFulfilled` and `$onRejected` will never be called more
+     than once.
+  3. `$onProgress` (deprecated) may be called multiple times.

+
+### ExtendedPromiseInterface
+
+The ExtendedPromiseInterface extends the PromiseInterface with useful shortcut
+and utility methods which are not part of the Promises/A specification.
+
+#### Implementations
+
+* [Promise](#promise-1)
+* [FulfilledPromise](#fulfilledpromise)
+* [RejectedPromise](#rejectedpromise)
+* [LazyPromise](#lazypromise)
+
+#### ExtendedPromiseInterface::done()
+
+```php
+$promise->done(callable $onFulfilled = null, callable $onRejected = null, callable $onProgress = null);
+```
+
+Consumes the promise's ultimate value if the promise fulfills, or handles the
+ultimate error.
+
+It will cause a fatal error if either `$onFulfilled` or `$onRejected` throw or
+return a rejected promise.
+
+Since the purpose of `done()` is consumption rather than transformation,
+`done()` always returns `null`.
+
+#### See also
+
+* [PromiseInterface::then()](#promiseinterfacethen)
+* [done() vs. then()](#done-vs-then)
+
+#### ExtendedPromiseInterface::otherwise()
+
+```php
+$promise->otherwise(callable $onRejected);
+```
+
+Registers a rejection handler for promise. It is a shortcut for:
+
+```php
+$promise->then(null, $onRejected);
+```
+
+Additionally, you can type hint the `$reason` argument of `$onRejected` to catch
+only specific errors.
+
+```php
+$promise
+    ->otherwise(function (\RuntimeException $reason) {
+        // Only catch \RuntimeException instances
+        // All other types of errors will propagate automatically
+    })
+    ->otherwise(function ($reason) {
+        // Catch other errors
+    )};
+```
+
+#### ExtendedPromiseInterface::always()
+
+```php
+$newPromise = $promise->always(callable $onFulfilledOrRejected);
+```
+
+Allows you to execute "cleanup" type tasks in a promise chain.
+
+It arranges for `$onFulfilledOrRejected` to be called, with no arguments,
+when the promise is either fulfilled or rejected.
+
+* If `$promise` fulfills, and `$onFulfilledOrRejected` returns successfully,
+  `$newPromise` will fulfill with the same value as `$promise`.
+* If `$promise` fulfills, and `$onFulfilledOrRejected` throws or returns a
+  rejected promise, `$newPromise` will reject with the thrown exception or
+  rejected promise's reason.
+* If `$promise` rejects, and `$onFulfilledOrRejected` returns successfully,
+  `$newPromise` will reject with the same reason as `$promise`.
+* If `$promise` rejects, and `$onFulfilledOrRejected` throws or returns a
+  rejected promise, `$newPromise` will reject with the thrown exception or
+  rejected promise's reason.
+
+`always()` behaves similarly to the synchronous finally statement. When combined
+with `otherwise()`, `always()` allows you to write code that is similar to the familiar
+synchronous catch/finally pair.
+
+Consider the following synchronous code:
+
+```php
+try {
+  return doSomething();
+} catch(\Exception $e) {
+    return handleError($e);
+} finally {
+    cleanup();
+}
+```
+
+Similar asynchronous code (with `doSomething()` that returns a promise) can be
+written:
+
+```php
+return doSomething()
+    ->otherwise('handleError')
+    ->always('cleanup');
+```
+
+#### ExtendedPromiseInterface::progress()
+
+> Deprecated in v2.6.0: Progress support is deprecated and should not be used anymore.
+
+```php
+$promise->progress(callable $onProgress);
+```
+
+Registers a handler for progress updates from promise. It is a shortcut for:
+
+```php
+$promise->then(null, null, $onProgress);
+```
+
+### CancellablePromiseInterface
+
+A cancellable promise provides a mechanism for consumers to notify the creator
+of the promise that they are not longer interested in the result of an
+operation.
+
+#### CancellablePromiseInterface::cancel()
+
+``` php
+$promise->cancel();
+```
+
+The `cancel()` method notifies the creator of the promise that there is no
+further interest in the results of the operation.
+
+Once a promise is settled (either fulfilled or rejected), calling `cancel()` on
+a promise has no effect.
+
+#### Implementations
+
+* [Promise](#promise-1)
+* [FulfilledPromise](#fulfilledpromise)
+* [RejectedPromise](#rejectedpromise)
+* [LazyPromise](#lazypromise)
+
+### Promise
+
+Creates a promise whose state is controlled by the functions passed to
+`$resolver`.
+
+```php
+$resolver = function (callable $resolve, callable $reject, callable $notify) {
+    // Do some work, possibly asynchronously, and then
+    // resolve or reject. You can notify of progress events (deprecated)
+    // along the way if you want/need.
+
+    $resolve($awesomeResult);
+    // or throw new Exception('Promise rejected');
+    // or $resolve($anotherPromise);
+    // or $reject($nastyError);
+    // or $notify($progressNotification);
+};
+
+$canceller = function () {
+    // Cancel/abort any running operations like network connections, streams etc.
+
+    // Reject promise by throwing an exception
+    throw new Exception('Promise cancelled');
+};
+
+$promise = new React\Promise\Promise($resolver, $canceller);
+```
+
+The promise constructor receives a resolver function and an optional canceller
+function which both will be called with 3 arguments:
+
+  * `$resolve($value)` - Primary function that seals the fate of the
+    returned promise. Accepts either a non-promise value, or another promise.
+    When called with a non-promise value, fulfills promise with that value.
+    When called with another promise, e.g. `$resolve($otherPromise)`, promise's
+    fate will be equivalent to that of `$otherPromise`.
+  * `$reject($reason)` - Function that rejects the promise. It is recommended to
+    just throw an exception instead of using `$reject()`.
+  * `$notify($update)` - Deprecated function that issues progress events for the promise.
+
+If the resolver or canceller throw an exception, the promise will be rejected
+with that thrown exception as the rejection reason.
+
+The resolver function will be called immediately, the canceller function only
+once all consumers called the `cancel()` method of the promise.
+
+### FulfilledPromise
+
+Creates a already fulfilled promise.
+
+```php
+$promise = React\Promise\FulfilledPromise($value);
+```
+
+Note, that `$value` **cannot** be a promise. It's recommended to use
+[resolve()](#resolve) for creating resolved promises.
+
+### RejectedPromise
+
+Creates a already rejected promise.
+
+```php
+$promise = React\Promise\RejectedPromise($reason);
+```
+
+Note, that `$reason` **cannot** be a promise. It's recommended to use
+[reject()](#reject) for creating rejected promises.
+
+### LazyPromise
+
+Creates a promise which will be lazily initialized by `$factory` once a consumer
+calls the `then()` method.
+
+```php
+$factory = function () {
+    $deferred = new React\Promise\Deferred();
+
+    // Do some heavy stuff here and resolve the deferred once completed
+
+    return $deferred->promise();
+};
+
+$promise = new React\Promise\LazyPromise($factory);
+
+// $factory will only be executed once we call then()
+$promise->then(function ($value) {
+});
+```
+
+### Functions
+
+Useful functions for creating, joining, mapping and reducing collections of
+promises.
+
+All functions working on promise collections (like `all()`, `race()`, `some()`
+etc.) support cancellation. This means, if you call `cancel()` on the returned
+promise, all promises in the collection are cancelled. If the collection itself
+is a promise which resolves to an array, this promise is also cancelled.
+
+#### resolve()
+
+```php
+$promise = React\Promise\resolve(mixed $promiseOrValue);
+```
+
+Creates a promise for the supplied `$promiseOrValue`.
+
+If `$promiseOrValue` is a value, it will be the resolution value of the
+returned promise.
+
+If `$promiseOrValue` is a thenable (any object that provides a `then()` method),
+a trusted promise that follows the state of the thenable is returned.
+
+If `$promiseOrValue` is a promise, it will be returned as is.
+
+Note: The promise returned is always a promise implementing
+[ExtendedPromiseInterface](#extendedpromiseinterface). If you pass in a custom
+promise which only implements [PromiseInterface](#promiseinterface), this
+promise will be assimilated to a extended promise following `$promiseOrValue`.
+
+#### reject()
+
+```php
+$promise = React\Promise\reject(mixed $promiseOrValue);
+```
+
+Creates a rejected promise for the supplied `$promiseOrValue`.
+
+If `$promiseOrValue` is a value, it will be the rejection value of the
+returned promise.
+
+If `$promiseOrValue` is a promise, its completion value will be the rejected
+value of the returned promise.
+
+This can be useful in situations where you need to reject a promise without
+throwing an exception. For example, it allows you to propagate a rejection with
+the value of another promise.
+
+#### all()
+
+```php
+$promise = React\Promise\all(array|React\Promise\PromiseInterface $promisesOrValues);
+```
+
+Returns a promise that will resolve only once all the items in
+`$promisesOrValues` have resolved. The resolution value of the returned promise
+will be an array containing the resolution values of each of the items in
+`$promisesOrValues`.
+
+#### race()
+
+```php
+$promise = React\Promise\race(array|React\Promise\PromiseInterface $promisesOrValues);
+```
+
+Initiates a competitive race that allows one winner. Returns a promise which is
+resolved in the same way the first settled promise resolves.
+
+#### any()
+
+```php
+$promise = React\Promise\any(array|React\Promise\PromiseInterface $promisesOrValues);
+```
+
+Returns a promise that will resolve when any one of the items in
+`$promisesOrValues` resolves. The resolution value of the returned promise
+will be the resolution value of the triggering item.
+
+The returned promise will only reject if *all* items in `$promisesOrValues` are
+rejected. The rejection value will be an array of all rejection reasons.
+
+The returned promise will also reject with a `React\Promise\Exception\LengthException`
+if `$promisesOrValues` contains 0 items.
+
+#### some()
+
+```php
+$promise = React\Promise\some(array|React\Promise\PromiseInterface $promisesOrValues, integer $howMany);
+```
+
+Returns a promise that will resolve when `$howMany` of the supplied items in
+`$promisesOrValues` resolve. The resolution value of the returned promise
+will be an array of length `$howMany` containing the resolution values of the
+triggering items.
+
+The returned promise will reject if it becomes impossible for `$howMany` items
+to resolve (that is, when `(count($promisesOrValues) - $howMany) + 1` items
+reject). The rejection value will be an array of
+`(count($promisesOrValues) - $howMany) + 1` rejection reasons.
+
+The returned promise will also reject with a `React\Promise\Exception\LengthException`
+if `$promisesOrValues` contains less items than `$howMany`.
+
+#### map()
+
+```php
+$promise = React\Promise\map(array|React\Promise\PromiseInterface $promisesOrValues, callable $mapFunc);
+```
+
+Traditional map function, similar to `array_map()`, but allows input to contain
+promises and/or values, and `$mapFunc` may return either a value or a promise.
+
+The map function receives each item as argument, where item is a fully resolved
+value of a promise or value in `$promisesOrValues`.
+
+#### reduce()
+
+```php
+$promise = React\Promise\reduce(array|React\Promise\PromiseInterface $promisesOrValues, callable $reduceFunc , $initialValue = null);
+```
+
+Traditional reduce function, similar to `array_reduce()`, but input may contain
+promises and/or values, and `$reduceFunc` may return either a value or a
+promise, *and* `$initialValue` may be a promise or a value for the starting
+value.
+
+### PromisorInterface
+
+The `React\Promise\PromisorInterface` provides a common interface for objects
+that provide a promise. `React\Promise\Deferred` implements it, but since it
+is part of the public API anyone can implement it.
+
+Examples
+--------
+
+### How to use Deferred
+
+```php
+function getAwesomeResultPromise()
+{
+    $deferred = new React\Promise\Deferred();
+
+    // Execute a Node.js-style function using the callback pattern
+    computeAwesomeResultAsynchronously(function ($error, $result) use ($deferred) {
+        if ($error) {
+            $deferred->reject($error);
+        } else {
+            $deferred->resolve($result);
+        }
+    });
+
+    // Return the promise
+    return $deferred->promise();
+}
+
+getAwesomeResultPromise()
+    ->then(
+        function ($value) {
+            // Deferred resolved, do something with $value
+        },
+        function ($reason) {
+            // Deferred rejected, do something with $reason
+        },
+        function ($update) {
+            // Progress notification triggered, do something with $update
+        }
+    );
+```
+
+### How promise forwarding works
+
+A few simple examples to show how the mechanics of Promises/A forwarding works.
+These examples are contrived, of course, and in real usage, promise chains will
+typically be spread across several function calls, or even several levels of
+your application architecture.
+
+#### Resolution forwarding
+
+Resolved promises forward resolution values to the next promise.
+The first promise, `$deferred->promise()`, will resolve with the value passed
+to `$deferred->resolve()` below.
+
+Each call to `then()` returns a new promise that will resolve with the return
+value of the previous handler. This creates a promise "pipeline".
+
+```php
+$deferred = new React\Promise\Deferred();
+
+$deferred->promise()
+    ->then(function ($x) {
+        // $x will be the value passed to $deferred->resolve() below
+        // and returns a *new promise* for $x + 1
+        return $x + 1;
+    })
+    ->then(function ($x) {
+        // $x === 2
+        // This handler receives the return value of the
+        // previous handler.
+        return $x + 1;
+    })
+    ->then(function ($x) {
+        // $x === 3
+        // This handler receives the return value of the
+        // previous handler.
+        return $x + 1;
+    })
+    ->then(function ($x) {
+        // $x === 4
+        // This handler receives the return value of the
+        // previous handler.
+        echo 'Resolve ' . $x;
+    });
+
+$deferred->resolve(1); // Prints "Resolve 4"
+```
+
+#### Rejection forwarding
+
+Rejected promises behave similarly, and also work similarly to try/catch:
+When you catch an exception, you must rethrow for it to propagate.
+
+Similarly, when you handle a rejected promise, to propagate the rejection,
+"rethrow" it by either returning a rejected promise, or actually throwing
+(since promise translates thrown exceptions into rejections)
+
+```php
+$deferred = new React\Promise\Deferred();
+
+$deferred->promise()
+    ->then(function ($x) {
+        throw new \Exception($x + 1);
+    })
+    ->otherwise(function (\Exception $x) {
+        // Propagate the rejection
+        throw $x;
+    })
+    ->otherwise(function (\Exception $x) {
+        // Can also propagate by returning another rejection
+        return React\Promise\reject(
+            new \Exception($x->getMessage() + 1)
+        );
+    })
+    ->otherwise(function ($x) {
+        echo 'Reject ' . $x->getMessage(); // 3
+    });
+
+$deferred->resolve(1);  // Prints "Reject 3"
+```
+
+#### Mixed resolution and rejection forwarding
+
+Just like try/catch, you can choose to propagate or not. Mixing resolutions and
+rejections will still forward handler results in a predictable way.
+
+```php
+$deferred = new React\Promise\Deferred();
+
+$deferred->promise()
+    ->then(function ($x) {
+        return $x + 1;
+    })
+    ->then(function ($x) {
+        throw new \Exception($x + 1);
+    })
+    ->otherwise(function (\Exception $x) {
+        // Handle the rejection, and don't propagate.
+        // This is like catch without a rethrow
+        return $x->getMessage() + 1;
+    })
+    ->then(function ($x) {
+        echo 'Mixed ' . $x; // 4
+    });
+
+$deferred->resolve(1);  // Prints "Mixed 4"
+```
+
+#### Progress event forwarding
+
+> Deprecated in v2.6.0: Progress support is deprecated and should not be used anymore.
+
+In the same way as resolution and rejection handlers, your progress handler
+**MUST** return a progress event to be propagated to the next link in the chain.
+If you return nothing, `null` will be propagated.
+
+Also in the same way as resolutions and rejections, if you don't register a
+progress handler, the update will be propagated through.
+
+If your progress handler throws an exception, the exception will be propagated
+to the next link in the chain. The best thing to do is to ensure your progress
+handlers do not throw exceptions.
+
+This gives you the opportunity to transform progress events at each step in the
+chain so that they are meaningful to the next step. It also allows you to choose
+not to transform them, and simply let them propagate untransformed, by not
+registering a progress handler.
+
+```php
+$deferred = new React\Promise\Deferred();
+
+$deferred->promise()
+    ->progress(function ($update) {
+        return $update + 1;
+    })
+    ->progress(function ($update) {
+        echo 'Progress ' . $update; // 2
+    });
+
+$deferred->notify(1);  // Prints "Progress 2"
+```
+
+### done() vs. then()
+
+The golden rule is:
+
+    Either return your promise, or call done() on it.
+
+At a first glance, `then()` and `done()` seem very similar. However, there are
+important distinctions.
+
+The intent of `then()` is to transform a promise's value and to pass or return
+a new promise for the transformed value along to other parts of your code.
+
+The intent of `done()` is to consume a promise's value, transferring
+responsibility for the value to your code.
+
+In addition to transforming a value, `then()` allows you to recover from, or
+propagate intermediate errors. Any errors that are not handled will be caught
+by the promise machinery and used to reject the promise returned by `then()`.
+
+Calling `done()` transfers all responsibility for errors to your code. If an
+error (either a thrown exception or returned rejection) escapes the
+`$onFulfilled` or `$onRejected` callbacks you provide to done, it will be
+rethrown in an uncatchable way causing a fatal error.
+
+```php
+function getJsonResult()
+{
+    return queryApi()
+        ->then(
+            // Transform API results to an object
+            function ($jsonResultString) {
+                return json_decode($jsonResultString);
+            },
+            // Transform API errors to an exception
+            function ($jsonErrorString) {
+                $object = json_decode($jsonErrorString);
+                throw new ApiErrorException($object->errorMessage);
+            }
+        );
+}
+
+// Here we provide no rejection handler. If the promise returned has been
+// rejected, the ApiErrorException will be thrown
+getJsonResult()
+    ->done(
+        // Consume transformed object
+        function ($jsonResultObject) {
+            // Do something with $jsonResultObject
+        }
+    );
+
+// Here we provide a rejection handler which will either throw while debugging
+// or log the exception
+getJsonResult()
+    ->done(
+        function ($jsonResultObject) {
+            // Do something with $jsonResultObject
+        },
+        function (ApiErrorException $exception) {
+            if (isDebug()) {
+                throw $exception;
+            } else {
+                logException($exception);
+            }
+        }
+    );
+```
+
+Note that if a rejection value is not an instance of `\Exception`, it will be
+wrapped in an exception of the type `React\Promise\UnhandledRejectionException`.
+
+You can get the original rejection reason by calling `$exception->getReason()`.
+

+# Changelog
+
+## 0.8.12 (2018-06-11)
+
+*   Feature: Improve memory consumption for failed and cancelled connection attempts.
+    (#161 by @clue)
+
+*   Improve test suite to fix Travis config to test against legacy PHP 5.3 again.
+    (#162 by @clue)
+
+## 0.8.11 (2018-04-24)
+
+*   Feature: Improve memory consumption for cancelled connection attempts and
+    simplify skipping DNS lookup when connecting to IP addresses.
+    (#159 and #160 by @clue)
+
+## 0.8.10 (2018-02-28)
+
+*   Feature: Update DNS dependency to support loading system default DNS
+    nameserver config on all supported platforms
+    (`/etc/resolv.conf` on Unix/Linux/Mac/Docker/WSL and WMIC on Windows)
+    (#152 by @clue)
+
+    This means that connecting to hosts that are managed by a local DNS server,
+    such as a corporate DNS server or when using Docker containers, will now
+    work as expected across all platforms with no changes required:
+
+    ```php
+    $connector = new Connector($loop);
+    $connector->connect('intranet.example:80')->then(function ($connection) {
+        // …
+    });
+    ```
+
+## 0.8.9 (2018-01-18)
+
+*   Feature: Support explicitly choosing TLS version to negotiate with remote side
+    by respecting `crypto_method` context parameter for all classes.
+    (#149 by @clue)
+
+    By default, all connector and server classes support TLSv1.0+ and exclude
+    support for legacy SSLv2/SSLv3. As of PHP 5.6+ you can also explicitly
+    choose the TLS version you want to negotiate with the remote side:
+
+    ```php
+    // new: now supports 'crypto_method` context parameter for all classes
+    $connector = new Connector($loop, array(
+        'tls' => array(
+            'crypto_method' => STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT
+        )
+    ));
+    ```
+
+*   Minor internal clean up to unify class imports
+    (#148 by @clue)
+
+## 0.8.8 (2018-01-06)
+
+*   Improve test suite by adding test group to skip integration tests relying on
+    internet connection and fix minor documentation typo.
+    (#146 by @clue and #145 by @cn007b)
+
+## 0.8.7 (2017-12-24)
+
+*   Fix: Fix closing socket resource before removing from loop
+    (#141 by @clue)
+
+    This fixes the root cause of an uncaught `Exception` that only manifested
+    itself after the recent Stream v0.7.4 component update and only if you're
+    using `ext-event` (`ExtEventLoop`).
+
+*   Improve test suite by testing against PHP 7.2
+    (#140 by @carusogabriel)
+
+## 0.8.6 (2017-11-18)
+
+*   Feature: Add Unix domain socket (UDS) support to `Server` with `unix://` URI scheme
+    and add advanced `UnixServer` class.
+    (#120 by @andig)
+
+    ```php
+    // new: Server now supports "unix://" scheme
+    $server = new Server('unix:///tmp/server.sock', $loop);
+
+    // new: advanced usage
+    $server = new UnixServer('/tmp/server.sock', $loop);
+    ```
+
+*   Restructure examples to ease getting started
+    (#136 by @clue)
+
+*   Improve test suite by adding forward compatibility with PHPUnit 6 and
+    ignore Mac OS X test failures for now until Travis tests work again
+    (#133 by @gabriel-caruso and #134 by @clue)
+
+## 0.8.5 (2017-10-23)
+
+*   Fix: Work around PHP bug with Unix domain socket (UDS) paths for Mac OS X
+    (#123 by @andig)
+
+*   Fix: Fix `SecureServer` to return `null` URI if server socket is already closed
+    (#129 by @clue)
+
+*   Improve test suite by adding forward compatibility with PHPUnit v5 and
+    forward compatibility with upcoming EventLoop releases in tests and
+    test Mac OS X on Travis
+    (#122 by @andig and #125, #127 and #130 by @clue)
+
+*   Readme improvements
+    (#118 by @jsor)
+
+## 0.8.4 (2017-09-16)
+
+*   Feature: Add `FixedUriConnector` decorator to use fixed, preconfigured URI instead
+    (#117 by @clue)
+
+    This can be useful for consumers that do not support certain URIs, such as
+    when you want to explicitly connect to a Unix domain socket (UDS) path
+    instead of connecting to a default address assumed by an higher-level API:
+
+    ```php
+    $connector = new FixedUriConnector(
+        'unix:///var/run/docker.sock',
+        new UnixConnector($loop)
+    );
+
+    // destination will be ignored, actually connects to Unix domain socket
+    $promise = $connector->connect('localhost:80');
+    ```
+
+## 0.8.3 (2017-09-08)
+
+*   Feature: Reduce memory consumption for failed connections
+    (#113 by @valga)
+
+*   Fix: Work around write chunk size for TLS streams for PHP < 7.1.14
+    (#114 by @clue)
+
+## 0.8.2 (2017-08-25)
+
+*   Feature: Update DNS dependency to support hosts file on all platforms
+    (#112 by @clue)
+
+    This means that connecting to hosts such as `localhost` will now work as
+    expected across all platforms with no changes required:
+
+    ```php
+    $connector = new Connector($loop);
+    $connector->connect('localhost:8080')->then(function ($connection) {
+        // …
+    });
+    ```
+
+## 0.8.1 (2017-08-15)
+
+* Feature: Forward compatibility with upcoming EventLoop v1.0 and v0.5 and
+  target evenement 3.0 a long side 2.0 and 1.0
+  (#104 by @clue and #111 by @WyriHaximus)
+
+* Improve test suite by locking Travis distro so new defaults will not break the build and
+  fix HHVM build for now again and ignore future HHVM build errors
+  (#109 and #110 by @clue)
+
+* Minor documentation fixes
+  (#103 by @christiaan and #108 by @hansott)
+
+## 0.8.0 (2017-05-09)
+
+* Feature: New `Server` class now acts as a facade for existing server classes
+  and renamed old `Server` to `TcpServer` for advanced usage.
+  (#96 and #97 by @clue)
+
+  The `Server` class is now the main class in this package that implements the
+  `ServerInterface` and allows you to accept incoming streaming connections,
+  such as plaintext TCP/IP or secure TLS connection streams.
+
+  > This is not a BC break and consumer code does not have to be updated.
+
+* Feature / BC break: All addresses are now URIs that include the URI scheme
+  (#98 by @clue)
+
+  ```diff
+  - $parts = parse_url('tcp://' . $conn->getRemoteAddress());
+  + $parts = parse_url($conn->getRemoteAddress());
+  ```
+
+* Fix: Fix `unix://` addresses for Unix domain socket (UDS) paths
+  (#100 by @clue)
+
+* Feature: Forward compatibility with Stream v1.0 and v0.7
+  (#99 by @clue)
+
+## 0.7.2 (2017-04-24)
+
+* Fix: Work around latest PHP 7.0.18 and 7.1.4 no longer accepting full URIs
+  (#94 by @clue)
+
+## 0.7.1 (2017-04-10)
+
+* Fix: Ignore HHVM errors when closing connection that is already closing
+  (#91 by @clue)
+
+## 0.7.0 (2017-04-10)
+
+* Feature: Merge SocketClient component into this component
+  (#87 by @clue)
+
+  This means that this package now provides async, streaming plaintext TCP/IP
+  and secure TLS socket server and client connections for ReactPHP.
+
+  ```
+  $connector = new React\Socket\Connector($loop);
+  $connector->connect('google.com:80')->then(function (ConnectionInterface $conn) {
+      $connection->write('…');
+  });
+  ```
+
+  Accordingly, the `ConnectionInterface` is now used to represent both incoming
+  server side connections as well as outgoing client side connections.
+
+  If you've previously used the SocketClient component to establish outgoing
+  client connections, upgrading should take no longer than a few minutes.
+  All classes have been merged as-is from the latest `v0.7.0` release with no
+  other changes, so you can simply update your code to use the updated namespace
+  like this:
+
+  ```php
+  // old from SocketClient component and namespace
+  $connector = new React\SocketClient\Connector($loop);
+  $connector->connect('google.com:80')->then(function (ConnectionInterface $conn) {
+      $connection->write('…');
+  });
+
+  // new
+  $connector = new React\Socket\Connector($loop);
+  $connector->connect('google.com:80')->then(function (ConnectionInterface $conn) {
+      $connection->write('…');
+  });
+  ```
+
+## 0.6.0 (2017-04-04)
+
+* Feature: Add `LimitingServer` to limit and keep track of open connections
+  (#86 by @clue)
+
+  ```php
+  $server = new Server(0, $loop);
+  $server = new LimitingServer($server, 100);
+
+  $server->on('connection', function (ConnectionInterface $connection) {
+      $connection->write('hello there!' . PHP_EOL);
+      …
+  });
+  ```
+
+* Feature / BC break: Add `pause()` and `resume()` methods to limit active
+  connections
+  (#84 by @clue)
+
+  ```php
+  $server = new Server(0, $loop);
+  $server->pause();
+
+  $loop->addTimer(1.0, function() use ($server) {
+      $server->resume();
+  });
+  ```
+
+## 0.5.1 (2017-03-09)
+
+* Feature: Forward compatibility with Stream v0.5 and upcoming v0.6
+  (#79 by @clue)
+
+## 0.5.0 (2017-02-14)
+
+* Feature / BC break: Replace `listen()` call with URIs passed to constructor
+  and reject listening on hostnames with `InvalidArgumentException`
+  and replace `ConnectionException` with `RuntimeException` for consistency
+  (#61, #66 and #72 by @clue)
+
+  ```php
+  // old
+  $server = new Server($loop);
+  $server->listen(8080);
+
+  // new
+  $server = new Server(8080, $loop);
+  ```
+
+  Similarly, you can now pass a full listening URI to the constructor to change
+  the listening host:
+
+  ```php
+  // old
+  $server = new Server($loop);
+  $server->listen(8080, '127.0.0.1');
+
+  // new
+  $server = new Server('127.0.0.1:8080', $loop);
+  ```
+
+  Trying to start listening on (DNS) host names will now throw an
+  `InvalidArgumentException`, use IP addresses instead:
+
+  ```php
+  // old
+  $server = new Server($loop);
+  $server->listen(8080, 'localhost');
+
+  // new
+  $server = new Server('127.0.0.1:8080', $loop);
+  ```
+
+  If trying to listen fails (such as if port is already in use or port below
+  1024 may require root access etc.), it will now throw a `RuntimeException`,
+  the `ConnectionException` class has been removed:
+
+  ```php
+  // old: throws React\Socket\ConnectionException
+  $server = new Server($loop);
+  $server->listen(80);
+
+  // new: throws RuntimeException
+  $server = new Server(80, $loop);
+  ```
+
+* Feature / BC break: Rename `shutdown()` to `close()` for consistency throughout React
+  (#62 by @clue)
+
+  ```php
+  // old
+  $server->shutdown();
+
+  // new
+  $server->close();
+  ```
+
+* Feature / BC break: Replace `getPort()` with `getAddress()`
+  (#67 by @clue)
+
+  ```php
+  // old
+  echo $server->getPort(); // 8080
+
+  // new
+  echo $server->getAddress(); // 127.0.0.1:8080
+  ```
+
+* Feature / BC break: `getRemoteAddress()` returns full address instead of only IP
+  (#65 by @clue)
+
+  ```php
+  // old
+  echo $connection->getRemoteAddress(); // 192.168.0.1
+
+  // new
+  echo $connection->getRemoteAddress(); // 192.168.0.1:51743
+  ```
+  
+* Feature / BC break: Add `getLocalAddress()` method
+  (#68 by @clue)
+
+  ```php
+  echo $connection->getLocalAddress(); // 127.0.0.1:8080
+  ```
+
+* BC break: The `Server` and `SecureServer` class are now marked `final`
+  and you can no longer `extend` them
+  (which was never documented or recommended anyway).
+  Public properties and event handlers are now internal only.
+  Please use composition instead of extension.
+  (#71, #70 and #69 by @clue)
+
+## 0.4.6 (2017-01-26)
+
+* Feature: Support socket context options passed to `Server`
+  (#64 by @clue)
+
+* Fix: Properly return `null` for unknown addresses

+
+* Bug fix: Reset socket to non-blocking after shutting down (PHP bug)
+
+## 0.4.0 (2014-02-02)

+# Socket
+
+[![Build Status](https://travis-ci.org/reactphp/socket.svg?branch=master)](https://travis-ci.org/reactphp/socket)
+
+Async, streaming plaintext TCP/IP and secure TLS socket server and client
+connections for [ReactPHP](https://reactphp.org/).
+
+The socket library provides re-usable interfaces for a socket-layer
+server and client based on the [`EventLoop`](https://github.com/reactphp/event-loop)
+and [`Stream`](https://github.com/reactphp/stream) components.
+Its server component allows you to build networking servers that accept incoming
+connections from networking clients (such as an HTTP server).
+Its client component allows you to build networking clients that establish
+outgoing connections to networking servers (such as an HTTP or database client).
+This library provides async, streaming means for all of this, so you can
+handle multiple concurrent connections without blocking.

+## Quickstart example
+
+Here is a server that closes the connection if you send it anything:
+
+```php
+$loop = React\EventLoop\Factory::create();
+$socket = new React\Socket\Server('127.0.0.1:8080', $loop);
+
+$socket->on('connection', function (ConnectionInterface $conn) {
+    $conn->write("Hello " . $conn->getRemoteAddress() . "!\n");
+    $conn->write("Welcome to this amazing server!\n");
+    $conn->write("Here's a tip: don't say anything.\n");
+
+    $conn->on('data', function ($data) use ($conn) {
+        $conn->close();
+    });
+});
+
+$loop->run();
+```
+
+See also the [examples](examples).
+
+Here's a client that outputs the output of said server and then attempts to
+send it a string:
+
+```php
+$loop = React\EventLoop\Factory::create();
+$connector = new React\Socket\Connector($loop);
+
+$connector->connect('127.0.0.1:8080')->then(function (ConnectionInterface $conn) use ($loop) {
+    $conn->pipe(new React\Stream\WritableResourceStream(STDOUT, $loop));
+    $conn->write("Hello World!\n");
+});
+
+$loop->run();
+```
+
+## Connection usage
+
+### ConnectionInterface
+
+The `ConnectionInterface` is used to represent any incoming and outgoing
+connection, such as a normal TCP/IP connection.
+
+An incoming or outgoing connection is a duplex stream (both readable and
+writable) that implements React's
+[`DuplexStreamInterface`](https://github.com/reactphp/stream#duplexstreaminterface).
+It contains additional properties for the local and remote address (client IP)
+where this connection has been established to/from.
+
+Most commonly, instances implementing this `ConnectionInterface` are emitted
+by all classes implementing the [`ServerInterface`](#serverinterface) and
+used by all classes implementing the [`ConnectorInterface`](#connectorinterface).
+
+Because the `ConnectionInterface` implements the underlying
+[`DuplexStreamInterface`](https://github.com/reactphp/stream#duplexstreaminterface)
+you can use any of its events and methods as usual:
+
+```php
+$connection->on('data', function ($chunk) {
+    echo $chunk;
+});
+
+$connection->on('end', function () {
+    echo 'ended';
+});
+
+$connection->on('error', function (Exception $e) {
+    echo 'error: ' . $e->getMessage();
+});
+
+$connection->on('close', function () {
+    echo 'closed';
+});
+
+$connection->write($data);
+$connection->end($data = null);
+$connection->close();
+// …
+```
+
+For more details, see the
+[`DuplexStreamInterface`](https://github.com/reactphp/stream#duplexstreaminterface).
+
+#### getRemoteAddress()
+
+The `getRemoteAddress(): ?string` method returns the full remote address
+(URI) where this connection has been established with.
+
+```php
+$address = $connection->getRemoteAddress();
+echo 'Connection with ' . $address . PHP_EOL;
+```
+
+If the remote address can not be determined or is unknown at this time (such as
+after the connection has been closed), it MAY return a `NULL` value instead.
+
+Otherwise, it will return the full address (URI) as a string value, such
+as `tcp://127.0.0.1:8080`, `tcp://[::1]:80`, `tls://127.0.0.1:443`,
+`unix://example.sock` or `unix:///path/to/example.sock`.
+Note that individual URI components are application specific and depend
+on the underlying transport protocol.
+
+If this is a TCP/IP based connection and you only want the remote IP, you may
+use something like this:
+
+```php
+$address = $connection->getRemoteAddress();
+$ip = trim(parse_url($address, PHP_URL_HOST), '[]');
+echo 'Connection with ' . $ip . PHP_EOL;
+```
+
+#### getLocalAddress()
+
+The `getLocalAddress(): ?string` method returns the full local address
+(URI) where this connection has been established with.
+
+```php
+$address = $connection->getLocalAddress();
+echo 'Connection with ' . $address . PHP_EOL;
+```
+
+If the local address can not be determined or is unknown at this time (such as
+after the connection has been closed), it MAY return a `NULL` value instead.
+
+Otherwise, it will return the full address (URI) as a string value, such
+as `tcp://127.0.0.1:8080`, `tcp://[::1]:80`, `tls://127.0.0.1:443`,
+`unix://example.sock` or `unix:///path/to/example.sock`.
+Note that individual URI components are application specific and depend
+on the underlying transport protocol.
+
+This method complements the [`getRemoteAddress()`](#getremoteaddress) method,
+so they should not be confused.
+
+If your `TcpServer` instance is listening on multiple interfaces (e.g. using
+the address `0.0.0.0`), you can use this method to find out which interface
+actually accepted this connection (such as a public or local interface).
+
+If your system has multiple interfaces (e.g. a WAN and a LAN interface),
+you can use this method to find out which interface was actually
+used for this connection.
+
+## Server usage
+
+### ServerInterface
+
+The `ServerInterface` is responsible for providing an interface for accepting
+incoming streaming connections, such as a normal TCP/IP connection.
+
+Most higher-level components (such as a HTTP server) accept an instance
+implementing this interface to accept incoming streaming connections.
+This is usually done via dependency injection, so it's fairly simple to actually
+swap this implementation against any other implementation of this interface.
+This means that you SHOULD typehint against this interface instead of a concrete
+implementation of this interface.
+
+Besides defining a few methods, this interface also implements the
+[`EventEmitterInterface`](https://github.com/igorw/evenement)
+which allows you to react to certain events.
+
+#### connection event
+
+The `connection` event will be emitted whenever a new connection has been
+established, i.e. a new client connects to this server socket:
+
+```php
+$server->on('connection', function (ConnectionInterface $connection) {
+    echo 'new connection' . PHP_EOL;
+});
+```
+
+See also the [`ConnectionInterface`](#connectioninterface) for more details
+about handling the incoming connection.
+
+#### error event
+
+The `error` event will be emitted whenever there's an error accepting a new
+connection from a client.
+
+```php
+$server->on('error', function (Exception $e) {
+    echo 'error: ' . $e->getMessage() . PHP_EOL;
+});
+```
+
+Note that this is not a fatal error event, i.e. the server keeps listening for
+new connections even after this event.
+
+
+#### getAddress()
+
+The `getAddress(): ?string` method can be used to
+return the full address (URI) this server is currently listening on.
+
+```php
+$address = $server->getAddress();
+echo 'Server listening on ' . $address . PHP_EOL;
+```
+
+If the address can not be determined or is unknown at this time (such as
+after the socket has been closed), it MAY return a `NULL` value instead.
+
+Otherwise, it will return the full address (URI) as a string value, such
+as `tcp://127.0.0.1:8080`, `tcp://[::1]:80`, `tls://127.0.0.1:443`
+`unix://example.sock` or `unix:///path/to/example.sock`.
+Note that individual URI components are application specific and depend
+on the underlying transport protocol.
+
+If this is a TCP/IP based server and you only want the local port, you may
+use something like this:
+
+```php
+$address = $server->getAddress();
+$port = parse_url($address, PHP_URL_PORT);
+echo 'Server listening on port ' . $port . PHP_EOL;
+```
+
+#### pause()
+
+The `pause(): void` method can be used to
+pause accepting new incoming connections.
+
+Removes the socket resource from the EventLoop and thus stop accepting
+new connections. Note that the listening socket stays active and is not
+closed.
+
+This means that new incoming connections will stay pending in the
+operating system backlog until its configurable backlog is filled.
+Once the backlog is filled, the operating system may reject further
+incoming connections until the backlog is drained again by resuming
+to accept new connections.
+
+Once the server is paused, no futher `connection` events SHOULD
+be emitted.
+
+```php
+$server->pause();
+
+$server->on('connection', assertShouldNeverCalled());
+```
+
+This method is advisory-only, though generally not recommended, the
+server MAY continue emitting `connection` events.
+
+Unless otherwise noted, a successfully opened server SHOULD NOT start
+in paused state.
+
+You can continue processing events by calling `resume()` again.
+
+Note that both methods can be called any number of times, in particular
+calling `pause()` more than once SHOULD NOT have any effect.
+Similarly, calling this after `close()` is a NO-OP.
+
+#### resume()
+
+The `resume(): void` method can be used to
+resume accepting new incoming connections.
+
+Re-attach the socket resource to the EventLoop after a previous `pause()`.
+
+```php
+$server->pause();
+
+$loop->addTimer(1.0, function () use ($server) {
+    $server->resume();
+});
+```
+
+Note that both methods can be called any number of times, in particular
+calling `resume()` without a prior `pause()` SHOULD NOT have any effect.
+Similarly, calling this after `close()` is a NO-OP.
+
+#### close()
+
+The `close(): void` method can be used to
+shut down this listening socket.
+
+This will stop listening for new incoming connections on this socket.
+
+```php
+echo 'Shutting down server socket' . PHP_EOL;
+$server->close();
+```
+
+Calling this method more than once on the same instance is a NO-OP.
+
+### Server
+
+The `Server` class is the main class in this package that implements the
+[`ServerInterface`](#serverinterface) and allows you to accept incoming
+streaming connections, such as plaintext TCP/IP or secure TLS connection streams.
+Connections can also be accepted on Unix domain sockets.
+
+```php
+$server = new Server(8080, $loop);
+```
+
+As above, the `$uri` parameter can consist of only a port, in which case the
+server will default to listening on the localhost address `127.0.0.1`,
+which means it will not be reachable from outside of this system.
+
+In order to use a random port assignment, you can use the port `0`:
+
+```php
+$server = new Server(0, $loop);
+$address = $server->getAddress();
+```
+
+In order to change the host the socket is listening on, you can provide an IP
+address through the first parameter provided to the constructor, optionally
+preceded by the `tcp://` scheme:
+
+```php
+$server = new Server('192.168.0.1:8080', $loop);
+```
+
+If you want to listen on an IPv6 address, you MUST enclose the host in square
+brackets:
+
+```php
+$server = new Server('[::1]:8080', $loop);
+```
+
+To listen on a Unix domain socket (UDS) path, you MUST prefix the URI with the
+`unix://` scheme:
+
+```php
+$server = new Server('unix:///tmp/server.sock', $loop);
+```
+
+If the given URI is invalid, does not contain a port, any other scheme or if it
+contains a hostname, it will throw an `InvalidArgumentException`:
+
+```php
+// throws InvalidArgumentException due to missing port
+$server = new Server('127.0.0.1', $loop);
+```
+
+If the given URI appears to be valid, but listening on it fails (such as if port
+is already in use or port below 1024 may require root access etc.), it will
+throw a `RuntimeException`:
+
+```php
+$first = new Server(8080, $loop);
+
+// throws RuntimeException because port is already in use
+$second = new Server(8080, $loop);
+```
+
+> Note that these error conditions may vary depending on your system and/or
+  configuration.
+  See the exception message and code for more details about the actual error
+  condition.
+
+Optionally, you can specify [TCP socket context options](http://php.net/manual/en/context.socket.php)
+for the underlying stream socket resource like this:
+
+```php
+$server = new Server('[::1]:8080', $loop, array(
+    'tcp' => array(
+        'backlog' => 200,
+        'so_reuseport' => true,
+        'ipv6_v6only' => true
+    )
+));
+```
+
+> Note that available [socket context options](http://php.net/manual/en/context.socket.php),
+  their defaults and effects of changing these may vary depending on your system
+  and/or PHP version.
+  Passing unknown context options has no effect.
+  For BC reasons, you can also pass the TCP socket context options as a simple
+  array without wrapping this in another array under the `tcp` key.
+
+You can start a secure TLS (formerly known as SSL) server by simply prepending
+the `tls://` URI scheme.
+Internally, it will wait for plaintext TCP/IP connections and then performs a
+TLS handshake for each connection.
+It thus requires valid [TLS context options](http://php.net/manual/en/context.ssl.php),
+which in its most basic form may look something like this if you're using a
+PEM encoded certificate file:
+
+```php
+$server = new Server('tls://127.0.0.1:8080', $loop, array(
+    'tls' => array(
+        'local_cert' => 'server.pem'
+    )
+));
+```
+
+> Note that the certificate file will not be loaded on instantiation but when an
+  incoming connection initializes its TLS context.
+  This implies that any invalid certificate file paths or contents will only cause
+  an `error` event at a later time.
+
+If your private key is encrypted with a passphrase, you have to specify it
+like this:
+
+```php
+$server = new Server('tls://127.0.0.1:8000', $loop, array(
+    'tls' => array(
+        'local_cert' => 'server.pem',
+        'passphrase' => 'secret'
+    )
+));
+```
+
+By default, this server supports TLSv1.0+ and excludes support for legacy
+SSLv2/SSLv3. As of PHP 5.6+ you can also explicitly choose the TLS version you
+want to negotiate with the remote side:
+
+```php
+$server = new Server('tls://127.0.0.1:8000', $loop, array(
+    'tls' => array(
+        'local_cert' => 'server.pem',
+        'crypto_method' => STREAM_CRYPTO_METHOD_TLSv1_2_SERVER
+    )
+));
+```
+
+> Note that available [TLS context options](http://php.net/manual/en/context.ssl.php),
+  their defaults and effects of changing these may vary depending on your system
+  and/or PHP version.
+  The outer context array allows you to also use `tcp` (and possibly more)
+  context options at the same time.
+  Passing unknown context options has no effect.
+  If you do not use the `tls://` scheme, then passing `tls` context options
+  has no effect.
+
+Whenever a client connects, it will emit a `connection` event with a connection
+instance implementing [`ConnectionInterface`](#connectioninterface):
+
+```php
+$server->on('connection', function (ConnectionInterface $connection) {
+    echo 'Plaintext connection from ' . $connection->getRemoteAddress() . PHP_EOL;
+    
+    $connection->write('hello there!' . PHP_EOL);
+    …
+});
+```
+
+See also the [`ServerInterface`](#serverinterface) for more details.
+
+> Note that the `Server` class is a concrete implementation for TCP/IP sockets.
+  If you want to typehint in your higher-level protocol implementation, you SHOULD
+  use the generic [`ServerInterface`](#serverinterface) instead.
+
+### Advanced server usage
+
+#### TcpServer
+
+The `TcpServer` class implements the [`ServerInterface`](#serverinterface) and
+is responsible for accepting plaintext TCP/IP connections.
+
+```php
+$server = new TcpServer(8080, $loop);

+
+#### SecureServer
+
+The `SecureServer` class implements the [`ServerInterface`](#serverinterface)

+
+Whenever a client completes the TLS handshake, it will emit a `connection` event
+with a connection instance implementing [`ConnectionInterface`](#connectioninterface):
+
+```php
+$server->on('connection', function (ConnectionInterface $connection) {
+    echo 'Secure connection from' . $connection->getRemoteAddress() . PHP_EOL;
+    
+    $connection->write('hello there!' . PHP_EOL);
+    …
+});
+```
+
+Whenever a client fails to perform a successful TLS handshake, it will emit an
+`error` event and then close the underlying TCP/IP connection:
+
+```php
+$server->on('error', function (Exception $e) {
+    echo 'Error' . $e->getMessage() . PHP_EOL;
+});
+```
+
+See also the [`ServerInterface`](#serverinterface) for more details.
+
+Note that the `SecureServer` class is a concrete implementation for TLS sockets.
+If you want to typehint in your higher-level protocol implementation, you SHOULD
+use the generic [`ServerInterface`](#serverinterface) instead.
+
+> Advanced usage: Despite allowing any `ServerInterface` as first parameter,
+you SHOULD pass a `TcpServer` instance as first parameter, unless you
+know what you're doing.
+Internally, the `SecureServer` has to set the required TLS context options on
+the underlying stream resources.
+These resources are not exposed through any of the interfaces defined in this
+package, but only through the internal `Connection` class.
+The `TcpServer` class is guaranteed to emit connections that implement
+the `ConnectionInterface` and uses the internal `Connection` class in order to
+expose these underlying resources.
+If you use a custom `ServerInterface` and its `connection` event does not
+meet this requirement, the `SecureServer` will emit an `error` event and
+then close the underlying connection.
+
+#### UnixServer
+
+The `UnixServer` class implements the [`ServerInterface`](#serverinterface) and
+is responsible for accepting connections on Unix domain sockets (UDS).
+
+```php
+$server = new UnixServer('/tmp/server.sock', $loop);
+```
+
+As above, the `$uri` parameter can consist of only a socket path or socket path
+prefixed by the `unix://` scheme.
+
+If the given URI appears to be valid, but listening on it fails (such as if the
+socket is already in use or the file not accessible etc.), it will throw a
+`RuntimeException`:
+
+```php
+$first = new UnixServer('/tmp/same.sock', $loop);
+
+// throws RuntimeException because socket is already in use
+$second = new UnixServer('/tmp/same.sock', $loop);
+```
+
+Whenever a client connects, it will emit a `connection` event with a connection
+instance implementing [`ConnectionInterface`](#connectioninterface):
+
+```php
+$server->on('connection', function (ConnectionInterface $connection) {
+    echo 'New connection' . PHP_EOL;
+
+    $connection->write('hello there!' . PHP_EOL);
+    …
+});
+```
+
+See also the [`ServerInterface`](#serverinterface) for more details.
+
+#### LimitingServer
+
+The `LimitingServer` decorator wraps a given `ServerInterface` and is responsible
+for limiting and keeping track of open connections to this server instance.
+
+Whenever the underlying server emits a `connection` event, it will check its
+limits and then either
+ - keep track of this connection by adding it to the list of
+   open connections and then forward the `connection` event
+ - or reject (close) the connection when its limits are exceeded and will
+   forward an `error` event instead.
+
+Whenever a connection closes, it will remove this connection from the list of
+open connections.
+
+```php
+$server = new LimitingServer($server, 100);
+$server->on('connection', function (ConnectionInterface $connection) {
+    $connection->write('hello there!' . PHP_EOL);
+    …
+});
+```
+
+See also the [second example](examples) for more details.
+
+You have to pass a maximum number of open connections to ensure
+the server will automatically reject (close) connections once this limit
+is exceeded. In this case, it will emit an `error` event to inform about
+this and no `connection` event will be emitted.
+
+```php
+$server = new LimitingServer($server, 100);
+$server->on('connection', function (ConnectionInterface $connection) {
+    $connection->write('hello there!' . PHP_EOL);
+    …
+});
+```
+
+You MAY pass a `null` limit in order to put no limit on the number of
+open connections and keep accepting new connection until you run out of
+operating system resources (such as open file handles). This may be
+useful if you do not want to take care of applying a limit but still want
+to use the `getConnections()` method.
+
+You can optionally configure the server to pause accepting new
+connections once the connection limit is reached. In this case, it will
+pause the underlying server and no longer process any new connections at
+all, thus also no longer closing any excessive connections.
+The underlying operating system is responsible for keeping a backlog of
+pending connections until its limit is reached, at which point it will
+start rejecting further connections.
+Once the server is below the connection limit, it will continue consuming
+connections from the backlog and will process any outstanding data on
+each connection.
+This mode may be useful for some protocols that are designed to wait for
+a response message (such as HTTP), but may be less useful for other
+protocols that demand immediate responses (such as a "welcome" message in
+an interactive chat).
+
+```php
+$server = new LimitingServer($server, 100, true);
+$server->on('connection', function (ConnectionInterface $connection) {
+    $connection->write('hello there!' . PHP_EOL);
+    …
+});
+```
+
+##### getConnections()
+
+The `getConnections(): ConnectionInterface[]` method can be used to
+return an array with all currently active connections.
+
+```php
+foreach ($server->getConnection() as $connection) {
+    $connection->write('Hi!');
+}
+```
+
+## Client usage
+
+### ConnectorInterface
+
+The `ConnectorInterface` is responsible for providing an interface for
+establishing streaming connections, such as a normal TCP/IP connection.
+
+This is the main interface defined in this package and it is used throughout
+React's vast ecosystem.
+
+Most higher-level components (such as HTTP, database or other networking
+service clients) accept an instance implementing this interface to create their
+TCP/IP connection to the underlying networking service.
+This is usually done via dependency injection, so it's fairly simple to actually
+swap this implementation against any other implementation of this interface.
+
+The interface only offers a single method:
+
+#### connect()
+
+The `connect(string $uri): PromiseInterface<ConnectionInterface, Exception>` method
+can be used to create a streaming connection to the given remote address.
+
+It returns a [Promise](https://github.com/reactphp/promise) which either
+fulfills with a stream implementing [`ConnectionInterface`](#connectioninterface)
+on success or rejects with an `Exception` if the connection is not successful:
+
+```php
+$connector->connect('google.com:443')->then(
+    function (ConnectionInterface $connection) {
+        // connection successfully established
+    },
+    function (Exception $error) {
+        // failed to connect due to $error
+    }
+);
+```
+
+See also [`ConnectionInterface`](#connectioninterface) for more details.
+
+The returned Promise MUST be implemented in such a way that it can be
+cancelled when it is still pending. Cancelling a pending promise MUST
+reject its value with an `Exception`. It SHOULD clean up any underlying
+resources and references as applicable:
+
+```php
+$promise = $connector->connect($uri);
+
+$promise->cancel();
+```
+
+### Connector
+
+The `Connector` class is the main class in this package that implements the
+[`ConnectorInterface`](#connectorinterface) and allows you to create streaming connections.
+
+You can use this connector to create any kind of streaming connections, such
+as plaintext TCP/IP, secure TLS or local Unix connection streams.
+
+It binds to the main event loop and can be used like this:
+
+```php
+$loop = React\EventLoop\Factory::create();
+$connector = new Connector($loop);
+
+$connector->connect($uri)->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+
+$loop->run();
+```
+
+In order to create a plaintext TCP/IP connection, you can simply pass a host
+and port combination like this:
+
+```php
+$connector->connect('www.google.com:80')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+> If you do no specify a URI scheme in the destination URI, it will assume
+  `tcp://` as a default and establish a plaintext TCP/IP connection.
+  Note that TCP/IP connections require a host and port part in the destination
+  URI like above, all other URI components are optional.
+
+In order to create a secure TLS connection, you can use the `tls://` URI scheme
+like this:
+
+```php
+$connector->connect('tls://www.google.com:443')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+In order to create a local Unix domain socket connection, you can use the
+`unix://` URI scheme like this:
+
+```php
+$connector->connect('unix:///tmp/demo.sock')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+> The [`getRemoteAddress()`](#getremoteaddress) method will return the target
+  Unix domain socket (UDS) path as given to the `connect()` method, including
+  the `unix://` scheme, for example `unix:///tmp/demo.sock`.
+  The [`getLocalAddress()`](#getlocaladdress) method will most likely return a
+  `null` value as this value is not applicable to UDS connections here.
+
+Under the hood, the `Connector` is implemented as a *higher-level facade*
+for the lower-level connectors implemented in this package. This means it
+also shares all of their features and implementation details.
+If you want to typehint in your higher-level protocol implementation, you SHOULD
+use the generic [`ConnectorInterface`](#connectorinterface) instead.
+
+The `Connector` class will try to detect your system DNS settings (and uses
+Google's public DNS server `8.8.8.8` as a fallback if unable to determine your
+system settings) to resolve all public hostnames into underlying IP addresses by
+default.
+If you explicitly want to use a custom DNS server (such as a local DNS relay or
+a company wide DNS server), you can set up the `Connector` like this:
+
+```php
+$connector = new Connector($loop, array(
+    'dns' => '127.0.1.1'
+));
+
+$connector->connect('localhost:80')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+If you do not want to use a DNS resolver at all and want to connect to IP
+addresses only, you can also set up your `Connector` like this:
+
+```php
+$connector = new Connector($loop, array(
+    'dns' => false
+));
+
+$connector->connect('127.0.0.1:80')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+Advanced: If you need a custom DNS `Resolver` instance, you can also set up
+your `Connector` like this:
+
+```php
+$dnsResolverFactory = new React\Dns\Resolver\Factory();
+$resolver = $dnsResolverFactory->createCached('127.0.1.1', $loop);
+
+$connector = new Connector($loop, array(
+    'dns' => $resolver
+));
+
+$connector->connect('localhost:80')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+By default, the `tcp://` and `tls://` URI schemes will use timeout value that
+repects your `default_socket_timeout` ini setting (which defaults to 60s).
+If you want a custom timeout value, you can simply pass this like this:
+
+```php
+$connector = new Connector($loop, array(
+    'timeout' => 10.0
+));
+```
+
+Similarly, if you do not want to apply a timeout at all and let the operating
+system handle this, you can pass a boolean flag like this:
+
+```php
+$connector = new Connector($loop, array(
+    'timeout' => false
+));
+```
+
+By default, the `Connector` supports the `tcp://`, `tls://` and `unix://`
+URI schemes. If you want to explicitly prohibit any of these, you can simply
+pass boolean flags like this:
+
+```php
+// only allow secure TLS connections
+$connector = new Connector($loop, array(
+    'tcp' => false,
+    'tls' => true,
+    'unix' => false,
+));
+
+$connector->connect('tls://google.com:443')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+The `tcp://` and `tls://` also accept additional context options passed to
+the underlying connectors.
+If you want to explicitly pass additional context options, you can simply
+pass arrays of context options like this:
+
+```php
+// allow insecure TLS connections
+$connector = new Connector($loop, array(
+    'tcp' => array(
+        'bindto' => '192.168.0.1:0'
+    ),
+    'tls' => array(
+        'verify_peer' => false,
+        'verify_peer_name' => false
+    ),
+));
+
+$connector->connect('tls://localhost:443')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+By default, this connector supports TLSv1.0+ and excludes support for legacy
+SSLv2/SSLv3. As of PHP 5.6+ you can also explicitly choose the TLS version you
+want to negotiate with the remote side:
+
+```php
+$connector = new Connector($loop, array(
+    'tls' => array(
+        'crypto_method' => STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT
+    )
+));
+```
+
+> For more details about context options, please refer to the PHP documentation
+  about [socket context options](http://php.net/manual/en/context.socket.php)
+  and [SSL context options](http://php.net/manual/en/context.ssl.php).
+
+Advanced: By default, the `Connector` supports the `tcp://`, `tls://` and
+`unix://` URI schemes.
+For this, it sets up the required connector classes automatically.
+If you want to explicitly pass custom connectors for any of these, you can simply
+pass an instance implementing the `ConnectorInterface` like this:
+
+```php
+$dnsResolverFactory = new React\Dns\Resolver\Factory();
+$resolver = $dnsResolverFactory->createCached('127.0.1.1', $loop);
+$tcp = new DnsConnector(new TcpConnector($loop), $resolver);
+
+$tls = new SecureConnector($tcp, $loop);
+
+$unix = new UnixConnector($loop);
+
+$connector = new Connector($loop, array(
+    'tcp' => $tcp,
+    'tls' => $tls,
+    'unix' => $unix,
+
+    'dns' => false,
+    'timeout' => false,
+));
+
+$connector->connect('google.com:80')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+> Internally, the `tcp://` connector will always be wrapped by the DNS resolver,
+  unless you disable DNS like in the above example. In this case, the `tcp://`
+  connector receives the actual hostname instead of only the resolved IP address
+  and is thus responsible for performing the lookup.
+  Internally, the automatically created `tls://` connector will always wrap the
+  underlying `tcp://` connector for establishing the underlying plaintext
+  TCP/IP connection before enabling secure TLS mode. If you want to use a custom
+  underlying `tcp://` connector for secure TLS connections only, you may
+  explicitly pass a `tls://` connector like above instead.
+  Internally, the `tcp://` and `tls://` connectors will always be wrapped by
+  `TimeoutConnector`, unless you disable timeouts like in the above example.
+
+### Advanced client usage
+
+#### TcpConnector
+
+The `React\Socket\TcpConnector` class implements the
+[`ConnectorInterface`](#connectorinterface) and allows you to create plaintext
+TCP/IP connections to any IP-port-combination:
+
+```php
+$tcpConnector = new React\Socket\TcpConnector($loop);
+
+$tcpConnector->connect('127.0.0.1:80')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+
+$loop->run();
+```
+
+See also the [examples](examples).
+
+Pending connection attempts can be cancelled by cancelling its pending promise like so:
+
+```php
+$promise = $tcpConnector->connect('127.0.0.1:80');
+
+$promise->cancel();
+```
+
+Calling `cancel()` on a pending promise will close the underlying socket
+resource, thus cancelling the pending TCP/IP connection, and reject the
+resulting promise.
+
+You can optionally pass additional
+[socket context options](http://php.net/manual/en/context.socket.php)
+to the constructor like this:
+
+```php
+$tcpConnector = new React\Socket\TcpConnector($loop, array(
+    'bindto' => '192.168.0.1:0'
+));
+```
+
+Note that this class only allows you to connect to IP-port-combinations.
+If the given URI is invalid, does not contain a valid IP address and port
+or contains any other scheme, it will reject with an
+`InvalidArgumentException`:
+
+If the given URI appears to be valid, but connecting to it fails (such as if
+the remote host rejects the connection etc.), it will reject with a
+`RuntimeException`.
+
+If you want to connect to hostname-port-combinations, see also the following chapter.
+
+> Advanced usage: Internally, the `TcpConnector` allocates an empty *context*
+resource for each stream resource.
+If the destination URI contains a `hostname` query parameter, its value will
+be used to set up the TLS peer name.
+This is used by the `SecureConnector` and `DnsConnector` to verify the peer
+name and can also be used if you want a custom TLS peer name.
+
+#### DnsConnector
+
+The `DnsConnector` class implements the
+[`ConnectorInterface`](#connectorinterface) and allows you to create plaintext
+TCP/IP connections to any hostname-port-combination.
+
+It does so by decorating a given `TcpConnector` instance so that it first
+looks up the given domain name via DNS (if applicable) and then establishes the
+underlying TCP/IP connection to the resolved target IP address.
+
+Make sure to set up your DNS resolver and underlying TCP connector like this:
+
+```php
+$dnsResolverFactory = new React\Dns\Resolver\Factory();
+$dns = $dnsResolverFactory->createCached('8.8.8.8', $loop);
+
+$dnsConnector = new React\Socket\DnsConnector($tcpConnector, $dns);
+
+$dnsConnector->connect('www.google.com:80')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+
+$loop->run();
+```
+
+See also the [examples](examples).
+
+Pending connection attempts can be cancelled by cancelling its pending promise like so:
+
+```php
+$promise = $dnsConnector->connect('www.google.com:80');
+
+$promise->cancel();
+```
+
+Calling `cancel()` on a pending promise will cancel the underlying DNS lookup
+and/or the underlying TCP/IP connection and reject the resulting promise.
+
+> Advanced usage: Internally, the `DnsConnector` relies on a `Resolver` to
+look up the IP address for the given hostname.
+It will then replace the hostname in the destination URI with this IP and
+append a `hostname` query parameter and pass this updated URI to the underlying
+connector.
+The underlying connector is thus responsible for creating a connection to the
+target IP address, while this query parameter can be used to check the original
+hostname and is used by the `TcpConnector` to set up the TLS peer name.
+If a `hostname` is given explicitly, this query parameter will not be modified,
+which can be useful if you want a custom TLS peer name.
+
+#### SecureConnector
+
+The `SecureConnector` class implements the
+[`ConnectorInterface`](#connectorinterface) and allows you to create secure
+TLS (formerly known as SSL) connections to any hostname-port-combination.
+
+It does so by decorating a given `DnsConnector` instance so that it first
+creates a plaintext TCP/IP connection and then enables TLS encryption on this
+stream.
+
+```php
+$secureConnector = new React\Socket\SecureConnector($dnsConnector, $loop);
+
+$secureConnector->connect('www.google.com:443')->then(function (ConnectionInterface $connection) {
+    $connection->write("GET / HTTP/1.0\r\nHost: www.google.com\r\n\r\n");
+    ...
+});
+
+$loop->run();
+```
+
+See also the [examples](examples).
+
+Pending connection attempts can be cancelled by cancelling its pending promise like so:
+
+```php
+$promise = $secureConnector->connect('www.google.com:443');
+
+$promise->cancel();
+```
+
+Calling `cancel()` on a pending promise will cancel the underlying TCP/IP
+connection and/or the SSL/TLS negotiation and reject the resulting promise.
+
+You can optionally pass additional
+[SSL context options](http://php.net/manual/en/context.ssl.php)
+to the constructor like this:
+
+```php
+$secureConnector = new React\Socket\SecureConnector($dnsConnector, $loop, array(
+    'verify_peer' => false,
+    'verify_peer_name' => false
+));
+```
+
+By default, this connector supports TLSv1.0+ and excludes support for legacy
+SSLv2/SSLv3. As of PHP 5.6+ you can also explicitly choose the TLS version you
+want to negotiate with the remote side:
+
+```php
+$secureConnector = new React\Socket\SecureConnector($dnsConnector, $loop, array(
+    'crypto_method' => STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT
+));
+```
+
+> Advanced usage: Internally, the `SecureConnector` relies on setting up the
+required *context options* on the underlying stream resource.
+It should therefor be used with a `TcpConnector` somewhere in the connector
+stack so that it can allocate an empty *context* resource for each stream
+resource and verify the peer name.
+Failing to do so may result in a TLS peer name mismatch error or some hard to
+trace race conditions, because all stream resources will use a single, shared
+*default context* resource otherwise.
+
+#### TimeoutConnector
+
+The `TimeoutConnector` class implements the
+[`ConnectorInterface`](#connectorinterface) and allows you to add timeout
+handling to any existing connector instance.
+
+It does so by decorating any given [`ConnectorInterface`](#connectorinterface)
+instance and starting a timer that will automatically reject and abort any
+underlying connection attempt if it takes too long.
+
+```php
+$timeoutConnector = new React\Socket\TimeoutConnector($connector, 3.0, $loop);
+
+$timeoutConnector->connect('google.com:80')->then(function (ConnectionInterface $connection) {
+    // connection succeeded within 3.0 seconds
+});
+```
+
+See also any of the [examples](examples).
+
+Pending connection attempts can be cancelled by cancelling its pending promise like so:
+
+```php
+$promise = $timeoutConnector->connect('google.com:80');
+
+$promise->cancel();
+```
+
+Calling `cancel()` on a pending promise will cancel the underlying connection
+attempt, abort the timer and reject the resulting promise.
+
+#### UnixConnector
+
+The `UnixConnector` class implements the
+[`ConnectorInterface`](#connectorinterface) and allows you to connect to
+Unix domain socket (UDS) paths like this:
+
+```php
+$connector = new React\Socket\UnixConnector($loop);
+
+$connector->connect('/tmp/demo.sock')->then(function (ConnectionInterface $connection) {
+    $connection->write("HELLO\n");
+});
+
+$loop->run();
+```
+
+Connecting to Unix domain sockets is an atomic operation, i.e. its promise will
+settle (either resolve or reject) immediately.
+As such, calling `cancel()` on the resulting promise has no effect.
+
+> The [`getRemoteAddress()`](#getremoteaddress) method will return the target
+  Unix domain socket (UDS) path as given to the `connect()` method, prepended
+  with the `unix://` scheme, for example `unix:///tmp/demo.sock`.
+  The [`getLocalAddress()`](#getlocaladdress) method will most likely return a
+  `null` value as this value is not applicable to UDS connections here.
+
+#### FixedUriConnector
+
+The `FixedUriConnector` class implements the
+[`ConnectorInterface`](#connectorinterface) and decorates an existing Connector
+to always use a fixed, preconfigured URI.
+
+This can be useful for consumers that do not support certain URIs, such as
+when you want to explicitly connect to a Unix domain socket (UDS) path
+instead of connecting to a default address assumed by an higher-level API:
+
+```php
+$connector = new FixedUriConnector(
+    'unix:///var/run/docker.sock',
+    new UnixConnector($loop)
+);
+
+// destination will be ignored, actually connects to Unix domain socket
+$promise = $connector->connect('localhost:80');
+```
+
+## Install
+
+The recommended way to install this library is [through Composer](https://getcomposer.org).
+[New to Composer?](https://getcomposer.org/doc/00-intro.md)
+
+This will install the latest supported version:
+
+```bash
+$ composer require react/socket:^0.8.12
+```
+
+See also the [CHANGELOG](CHANGELOG.md) for details about version upgrades.
+
+This project aims to run on any platform and thus does not require any PHP
+extensions and supports running on legacy PHP 5.3 through current PHP 7+ and HHVM.
+It's *highly recommended to use PHP 7+* for this project, partly due to its vast
+performance improvements and partly because legacy PHP versions require several
+workarounds as described below.
+
+Secure TLS connections received some major upgrades starting with PHP 5.6, with
+the defaults now being more secure, while older versions required explicit
+context options.
+This library does not take responsibility over these context options, so it's
+up to consumers of this library to take care of setting appropriate context
+options as described above.
+
+All versions of PHP prior to 5.6.8 suffered from a buffering issue where reading
+from a streaming TLS connection could be one `data` event behind.
+This library implements a work-around to try to flush the complete incoming
+data buffers on these legacy PHP versions, which has a penalty of around 10% of
+throughput on all connections.
+With this work-around, we have not been able to reproduce this issue anymore,
+but we have seen reports of people saying this could still affect some of the
+older PHP versions (`5.5.23`, `5.6.7`, and `5.6.8`).
+Note that this only affects *some* higher-level streaming protocols, such as
+IRC over TLS, but should not affect HTTP over TLS (HTTPS).
+Further investigation of this issue is needed.
+For more insights, this issue is also covered by our test suite.
+
+PHP < 7.1.4 (and PHP < 7.0.18) suffers from a bug when writing big
+chunks of data over TLS streams at once.
+We try to work around this by limiting the write chunk size to 8192
+bytes for older PHP versions only.
+This is only a work-around and has a noticable performance penalty on
+affected versions.
+
+This project also supports running on HHVM.
+Note that really old HHVM < 3.8 does not support secure TLS connections, as it
+lacks the required `stream_socket_enable_crypto()` function.
+As such, trying to create a secure TLS connections on affected versions will
+return a rejected promise instead.
+This issue is also covered by our test suite, which will skip related tests
+on affected versions.
+
+## Tests
+
+To run the test suite, you first need to clone this repo and then install all
+dependencies [through Composer](https://getcomposer.org):
+
+```bash
+$ composer install
+```
+
+To run the test suite, go to the project root and run:
+
+```bash
+$ php vendor/bin/phpunit
+```
+
+The test suite also contains a number of functional integration tests that rely
+on a stable internet connection.
+If you do not want to run these, they can simply be skipped like this:
+
+```bash
+$ php vendor/bin/phpunit --exclude-group internet
+```

+     * This implies that any invalid certificate file paths or contents will only cause
+     * an `error` event at a later time.
+     *
+     * If your private key is encrypted with a passphrase, you have to specify it
+     * like this:
+     *
+     * ```php
+     * $server = new TcpServer(8000, $loop);

+     * ));
+     * ```
+     *
+     * Note that available [TLS context options],
+     * their defaults and effects of changing these may vary depending on your system
+     * and/or PHP version.
+     * Passing unknown context options has no effect.
+     *
+     * Advanced usage: Despite allowing any `ServerInterface` as first parameter,
+     * you SHOULD pass a `TcpServer` instance as first parameter, unless you
+     * know what you're doing.
+     * Internally, the `SecureServer` has to set the required TLS context options on
+     * the underlying stream resources.
+     * These resources are not exposed through any of the interfaces defined in this
+     * package, but only through the internal `Connection` class.
+     * The `TcpServer` class is guaranteed to emit connections that implement
+     * the `ConnectionInterface` and uses the internal `Connection` class in order to
+     * expose these underlying resources.
+     * If you use a custom `ServerInterface` and its `connection` event does not
+     * meet this requirement, the `SecureServer` will emit an `error` event and

+ *
+ * connection event:
+ *     The `connection` event will be emitted whenever a new connection has been
+ *     established, i.e. a new client connects to this server socket:

+ *     $server->on('connection', function (ConnectionInterface $connection) {

+ *     });
+ *     ```
+ *
+ *     See also the `ConnectionInterface` for more details about handling the
+ *     incoming connection.
+ *
+ * error event:
+ *     The `error` event will be emitted whenever there's an error accepting a new
+ *     connection from a client.
+ *
+ *     ```php
+ *     $server->on('error', function (Exception $e) {
+ *         echo 'error: ' . $e->getMessage() . PHP_EOL;

+     * ```

+     * If the given URI appears to be valid, but listening on it fails (such as if port
+     * is already in use or port below 1024 may require root access etc.), it will
+     * throw a `RuntimeException`:

+# Changelog
+
+## 1.1.0 (2018-01-01)
+
+*   Improvement: Increase performance by optimizing global function and constant look ups
+    (#137 by @WyriHaximus)
+*   Travis: Test against PHP 7.3
+    (#138 by @WyriHaximus)
+*   Fix: Ignore empty reads 
+    (#139 by @WyriHaximus)
+
+## 1.0.0 (2018-07-11)
+
+*   First stable LTS release, now following [SemVer](https://semver.org/).
+    We'd like to emphasize that this component is production ready and battle-tested.
+    We plan to support all long-term support (LTS) releases for at least 24 months,
+    so you have a rock-solid foundation to build on top of.
+
+>   Contains no other changes, so it's actually fully compatible with the v0.7.7 release.
+
+## 0.7.7 (2018-01-19)
+
+*   Improve test suite by fixing forward compatibility with upcoming EventLoop
+    releases, avoid risky tests and add test group to skip integration tests
+    relying on internet connection and apply appropriate test timeouts.
+    (#128, #131 and #132 by @clue)
+
+## 0.7.6 (2017-12-21)
+
+*   Fix: Work around reading from unbuffered pipe stream in legacy PHP < 5.4.28 and PHP < 5.5.12
+    (#126 by @clue)
+
+*   Improve test suite by simplifying test bootstrapping logic via Composer and
+    test against PHP 7.2
+    (#127 by @clue and #124 by @carusogabriel)
+
+## 0.7.5 (2017-11-20)
+
+*   Fix: Igore excessive `fopen()` mode flags for `WritableResourceStream`
+    (#119 by @clue)
+
+*   Fix: Fix forward compatibility with upcoming EventLoop releases
+    (#121 by @clue)
+
+*   Restructure examples to ease getting started
+    (#123 by @clue)
+
+*   Improve test suite by adding forward compatibility with PHPUnit 6 and
+    ignore Mac OS X test failures for now until Travis tests work again
+    (#122 by @gabriel-caruso and #120 by @clue)
+
+## 0.7.4 (2017-10-11)
+
+*   Fix: Remove event listeners from `CompositeStream` once closed and
+    remove undocumented left-over `close` event argument
+    (#116 by @clue)
+
+*   Minor documentation improvements: Fix wrong class name in example,
+    fix typos in README and
+    fix forward compatibility with upcoming EventLoop releases in example
+    (#113 by @docteurklein and #114 and #115 by @clue)
+
+*   Improve test suite by running against Mac OS X on Travis
+    (#112 by @clue)
+
+## 0.7.3 (2017-08-05)
+
+*   Improvement: Support Événement 3.0 a long side 2.0 and 1.0
+    (#108 by @WyriHaximus)
+
+*   Readme: Corrected loop initialization in usage example
+    (#109 by @pulyavin)
+
+*   Travis: Lock linux distribution preventing future builds from breaking
+    (#110 by @clue)
+
+## 0.7.2 (2017-06-15)
+
+*   Bug fix: WritableResourceStream: Close the underlying stream when closing the stream.
+    (#107 by @WyriHaximus)  
+
+## 0.7.1 (2017-05-20)
+
+*   Feature: Add optional `$writeChunkSize` parameter to limit maximum number of
+    bytes to write at once.
+    (#105 by @clue)
+
+    ```php
+    $stream = new WritableResourceStream(STDOUT, $loop, null, 8192);
+    ```
+
+*   Ignore HHVM test failures for now until Travis tests work again
+    (#106 by @clue)
+
+## 0.7.0 (2017-05-04)
+
+*   Removed / BC break: Remove deprecated and unneeded functionality
+    (#45, #87, #90, #91 and #93 by @clue)
+
+    *   Remove deprecated `Stream` class, use `DuplexResourceStream` instead
+        (#87 by @clue)
+      
+    *   Remove public `$buffer` property, use new constructor parameters instead
+        (#91 by @clue)
+
+    *   Remove public `$stream` property from all resource streams
+        (#90 by @clue)
+
+    *   Remove undocumented and now unused `ReadableStream` and `WritableStream`
+        (#93 by @clue)
+
+    *   Remove `BufferedSink`
+        (#45 by @clue)
+
+*   Feature / BC break: Simplify `ThroughStream` by using data callback instead of
+    inheritance. It is now a direct implementation of `DuplexStreamInterface`.
+    (#88 and #89 by @clue)
+
+    ```php
+    $through = new ThroughStream(function ($data) {
+        return json_encode($data) . PHP_EOL;
+    });
+    $through->on('data', $this->expectCallableOnceWith("[2, true]\n"));
+
+    $through->write(array(2, true));
+    ```
+
+*   Feature / BC break: The `CompositeStream` starts closed if either side is
+    already closed and forwards pause to pipe source on first write attempt.
+    (#96 and #103 by @clue)
+    
+    If either side of the composite stream closes, it will also close the other
+    side. We now also ensure that if either side is already closed during
+    instantiation, it will also close the other side.
+
+*   BC break: Mark all classes as `final` and
+    mark internal API as `private` to discourage inheritance
+    (#95 and #99 by @clue)
+
+*   Feature / BC break: Only emit `error` event for fatal errors
+    (#92 by @clue)
+
+    >   The `error` event was previously also allowed to be emitted for non-fatal
+        errors, but our implementations actually only ever emitted this as a fatal
+        error and then closed the stream.
+
+*   Feature: Explicitly allow custom events and exclude any semantics
+    (#97 by @clue)
+
+*   Strict definition for event callback functions
+    (#101 by @clue)
+
+*   Support legacy PHP 5.3 through PHP 7.1 and HHVM and improve usage documentation
+    (#100 and #102 by @clue)
+
+*   Actually require all dependencies so this is self-contained and improve
+    forward compatibility with EventLoop v1.0 and v0.5
+    (#94 and #98 by @clue)
+
+## 0.6.0 (2017-03-26)
+
+* Feature / Fix / BC break: Add `DuplexResourceStream` and deprecate `Stream`
+  (#85 by @clue)
+
+  ```php
+  // old (does still work for BC reasons)
+  $stream = new Stream($connection, $loop);
+
+  // new
+  $stream = new DuplexResourceStream($connection, $loop);
+  ```
+
+  Note that the `DuplexResourceStream` now rejects read-only or write-only
+  streams, so this may affect BC. If you want a read-only or write-only
+  resource, use `ReadableResourceStream` or `WritableResourceStream` instead of
+  `DuplexResourceStream`.
+
+  > BC note: This class was previously called `Stream`. The `Stream` class still
+    exists for BC reasons and will be removed in future versions of this package.
+
+* Feature / BC break: Add `WritableResourceStream` (previously called `Buffer`)
+  (#84 by @clue)
+
+  ```php
+  // old
+  $stream = new Buffer(STDOUT, $loop);
+
+  // new
+  $stream = new WritableResourceStream(STDOUT, $loop);
+  ```
+
+* Feature: Add `ReadableResourceStream`
+  (#83 by @clue)
+
+  ```php
+  $stream = new ReadableResourceStream(STDIN, $loop);
+  ```
+
+* Fix / BC Break: Enforce using non-blocking I/O
+  (#46 by @clue)
+
+  > BC note: This is known to affect process pipes on Windows which do not
+    support non-blocking I/O and could thus block the whole EventLoop previously.
+
+* Feature / Fix / BC break: Consistent semantics for
+  `DuplexStreamInterface::end()` to ensure it SHOULD also end readable side
+  (#86 by @clue)
+
+* Fix: Do not use unbuffered reads on pipe streams for legacy PHP < 5.4
+  (#80 by @clue)
+
+## 0.5.0 (2017-03-08)
+
+* Feature / BC break: Consistent `end` event semantics (EOF)
+  (#70 by @clue)
+  
+  The `end` event will now only be emitted for a *successful* end, not if the
+  stream closes due to an unrecoverable `error` event or if you call `close()`
+  explicitly.
+  If you want to detect when the stream closes (terminates), use the `close`
+  event instead.
+
+* BC break: Remove custom (undocumented) `full-drain` event from `Buffer`
+  (#63 and #68 by @clue)
+
+  > The `full-drain` event was undocumented and mostly used internally.
+    Relying on this event has attracted some low-quality code in the past, so
+    we've removed this from the public API in order to work out a better
+    solution instead.
+    If you want to detect when the buffer finishes flushing data to the stream,
+    you may want to look into its `end()` method or the `close` event instead.
+
+* Feature / BC break: Consistent event semantics and documentation,
+  explicitly state *when* events will be emitted and *which* arguments they
+  receive.
+  (#73 and #69 by @clue)
+
+  The documentation now explicitly defines each event and its arguments.
+  Custom events and event arguments are still supported.
+  Most notably, all defined events only receive inherently required event
+  arguments and no longer transmit the instance they are emitted on for
+  consistency and performance reasons.
+
+  ```php
+  // old (inconsistent and not supported by all implementations)
+  $stream->on('data', function ($data, $stream) {
+      // process $data
+  });
+
+  // new (consistent throughout the whole ecosystem)
+  $stream->on('data', function ($data) use ($stream) {
+      // process $data
+  });
+  ```
+
+  > This mostly adds documentation (and thus some stricter, consistent 
+    definitions) for the existing behavior, it does NOT define any major
+    changes otherwise.
+    Most existing code should be compatible with these changes, unless
+    it relied on some undocumented/unintended semantics.
+
+* Feature / BC break: Consistent method semantics and documentation
+  (#72 by @clue)
+
+  > This mostly adds documentation (and thus some stricter, consistent
+    definitions) for the existing behavior, it does NOT define any major
+    changes otherwise.
+    Most existing code should be compatible with these changes, unless
+    it relied on some undocumented/unintended semantics.
+
+* Feature: Consistent `pipe()` semantics for closed and closing streams
+  (#71 from @clue)
+
+  The source stream will now always be paused via `pause()` when the
+  destination stream closes. Also, properly stop piping if the source
+  stream closes and remove all event forwarding.
+
+* Improve test suite by adding PHPUnit to `require-dev` and improving coverage.
+  (#74 and #75 by @clue, #66 by @nawarian)

+  (#60 by @clue)
+
+* Fix: Consistent `close` event behavior for `Buffer`

+
+## 0.4.5 (2016-11-13)
+
+* Feature: Support setting read buffer size to `null` (infinite)
+  (#42 by @clue)
+
+* Fix: Do not emit `full-drain` event if `Buffer` is closed during `drain` event
+  (#55 by @clue)
+
+* Vastly improved performance by factor of 10x to 20x.
+  Raise default buffer sizes to 64 KiB and simplify and improve error handling
+  and unneeded function calls.
+  (#53, #55, #56 by @clue)
+
+## 0.4.4 (2016-08-22)

+  stream resource fails with a permanent error.
+  (#52 and #40 by @clue, #25 by @lysenkobv)
+
+* Bug fix: Do not emit empty `data` event if nothing has been read (stream reached EOF)
+  (#39 by @clue)
+
+* Bug fix: Ignore empty writes to `Buffer`
+  (#51 by @clue)
+
+* Add benchmarking script to measure throughput in CI

+
+Event-driven readable and writable streams for non-blocking I/O in [ReactPHP](https://reactphp.org/).
+
+In order to make the [EventLoop](https://github.com/reactphp/event-loop)
+easier to use, this component introduces the powerful concept of "streams".
+Streams allow you to efficiently process huge amounts of data (such as a multi
+Gigabyte file download) in small chunks without having to store everything in
+memory at once.
+They are very similar to the streams found in PHP itself,
+but have an interface more suited for async, non-blocking I/O.

+## Stream usage
+
+ReactPHP uses the concept of "streams" throughout its ecosystem to provide a
+consistent higher-level abstraction for processing streams of arbitrary data
+contents and size.
+While a stream itself is a quite low-level concept, it can be used as a powerful
+abstraction to build higher-level components and protocols on top.
+
+If you're new to this concept, it helps to think of them as a water pipe:
+You can consume water from a source or you can produce water and forward (pipe)
+it to any destination (sink).
+
+Similarly, streams can either be
+
+* readable (such as `STDIN` terminal input) or
+* writable (such as `STDOUT` terminal output) or
+* duplex (both readable *and* writable, such as a TCP/IP connection)
+
+Accordingly, this package defines the following three interfaces
+
+* [`ReadableStreamInterface`](#readablestreaminterface)
+* [`WritableStreamInterface`](#writablestreaminterface)
+* [`DuplexStreamInterface`](#duplexstreaminterface)
+
+### ReadableStreamInterface
+
+The `ReadableStreamInterface` is responsible for providing an interface for
+read-only streams and the readable side of duplex streams.
+
+Besides defining a few methods, this interface also implements the
+`EventEmitterInterface` which allows you to react to certain events.
+
+The event callback functions MUST be a valid `callable` that obeys strict
+parameter definitions and MUST accept event parameters exactly as documented.
+The event callback functions MUST NOT throw an `Exception`.
+The return value of the event callback functions will be ignored and has no
+effect, so for performance reasons you're recommended to not return any
+excessive data structures.
+
+Every implementation of this interface MUST follow these event semantics in
+order to be considered a well-behaving stream.
+
+> Note that higher-level implementations of this interface may choose to
+  define additional events with dedicated semantics not defined as part of
+  this low-level stream specification. Conformance with these event semantics
+  is out of scope for this interface, so you may also have to refer to the
+  documentation of such a higher-level implementation.
+
+#### data event
+
+The `data` event will be emitted whenever some data was read/received
+from this source stream.
+The event receives a single mixed argument for incoming data.
+
+```php
+$stream->on('data', function ($data) {
+    echo $data;
+});
+```
+
+This event MAY be emitted any number of times, which may be zero times if
+this stream does not send any data at all.
+It SHOULD not be emitted after an `end` or `close` event.
+
+The given `$data` argument may be of mixed type, but it's usually
+recommended it SHOULD be a `string` value or MAY use a type that allows
+representation as a `string` for maximum compatibility.
+
+Many common streams (such as a TCP/IP connection or a file-based stream)
+will emit the raw (binary) payload data that is received over the wire as
+chunks of `string` values.
+
+Due to the stream-based nature of this, the sender may send any number
+of chunks with varying sizes. There are no guarantees that these chunks
+will be received with the exact same framing the sender intended to send.
+In other words, many lower-level protocols (such as TCP/IP) transfer the
+data in chunks that may be anywhere between single-byte values to several
+dozens of kilobytes. You may want to apply a higher-level protocol to
+these low-level data chunks in order to achieve proper message framing.
+  
+#### end event
+
+The `end` event will be emitted once the source stream has successfully
+reached the end of the stream (EOF).
+
+```php
+$stream->on('end', function () {
+    echo 'END';
+});
+```
+
+This event SHOULD be emitted once or never at all, depending on whether
+a successful end was detected.
+It SHOULD NOT be emitted after a previous `end` or `close` event.
+It MUST NOT be emitted if the stream closes due to a non-successful
+end, such as after a previous `error` event.
+
+After the stream is ended, it MUST switch to non-readable mode,
+see also `isReadable()`.
+
+This event will only be emitted if the *end* was reached successfully,
+not if the stream was interrupted by an unrecoverable error or explicitly
+closed. Not all streams know this concept of a "successful end".
+Many use-cases involve detecting when the stream closes (terminates)
+instead, in this case you should use the `close` event.
+After the stream emits an `end` event, it SHOULD usually be followed by a
+`close` event.
+
+Many common streams (such as a TCP/IP connection or a file-based stream)
+will emit this event if either the remote side closes the connection or
+a file handle was successfully read until reaching its end (EOF).
+
+Note that this event should not be confused with the `end()` method.
+This event defines a successful end *reading* from a source stream, while
+the `end()` method defines *writing* a successful end to a destination
+stream.
+
+#### error event
+
+The `error` event will be emitted once a fatal error occurs, usually while
+trying to read from this stream.
+The event receives a single `Exception` argument for the error instance.
+
+```php
+$server->on('error', function (Exception $e) {
+    echo 'Error: ' . $e->getMessage() . PHP_EOL;
+});
+```
+
+This event SHOULD be emitted once the stream detects a fatal error, such
+as a fatal transmission error or after an unexpected `data` or premature
+`end` event.
+It SHOULD NOT be emitted after a previous `error`, `end` or `close` event.
+It MUST NOT be emitted if this is not a fatal error condition, such as
+a temporary network issue that did not cause any data to be lost.
+
+After the stream errors, it MUST close the stream and SHOULD thus be
+followed by a `close` event and then switch to non-readable mode, see
+also `close()` and `isReadable()`.
+
+Many common streams (such as a TCP/IP connection or a file-based stream)
+only deal with data transmission and do not make assumption about data
+boundaries (such as unexpected `data` or premature `end` events).
+In other words, many lower-level protocols (such as TCP/IP) may choose
+to only emit this for a fatal transmission error once and will then
+close (terminate) the stream in response.
+
+If this stream is a `DuplexStreamInterface`, you should also notice
+how the writable side of the stream also implements an `error` event.
+In other words, an error may occur while either reading or writing the
+stream which should result in the same error processing.
+
+#### close event
+
+The `close` event will be emitted once the stream closes (terminates).
+
+```php
+$stream->on('close', function () {
+    echo 'CLOSED';
+});
+```
+
+This event SHOULD be emitted once or never at all, depending on whether
+the stream ever terminates.
+It SHOULD NOT be emitted after a previous `close` event.
+
+After the stream is closed, it MUST switch to non-readable mode,
+see also `isReadable()`.
+
+Unlike the `end` event, this event SHOULD be emitted whenever the stream
+closes, irrespective of whether this happens implicitly due to an
+unrecoverable error or explicitly when either side closes the stream.
+If you only want to detect a *successful* end, you should use the `end`
+event instead.
+
+Many common streams (such as a TCP/IP connection or a file-based stream)
+will likely choose to emit this event after reading a *successful* `end`
+event or after a fatal transmission `error` event.
+
+If this stream is a `DuplexStreamInterface`, you should also notice
+how the writable side of the stream also implements a `close` event.
+In other words, after receiving this event, the stream MUST switch into
+non-writable AND non-readable mode, see also `isWritable()`.
+Note that this event should not be confused with the `end` event.
+
+#### isReadable()
+
+The `isReadable(): bool` method can be used to
+check whether this stream is in a readable state (not closed already).
+
+This method can be used to check if the stream still accepts incoming
+data events or if it is ended or closed already.
+Once the stream is non-readable, no further `data` or `end` events SHOULD
+be emitted.
+
+```php
+assert($stream->isReadable() === false);
+
+$stream->on('data', assertNeverCalled());
+$stream->on('end', assertNeverCalled());
+```
+
+A successfully opened stream always MUST start in readable mode.
+
+Once the stream ends or closes, it MUST switch to non-readable mode.
+This can happen any time, explicitly through `close()` or
+implicitly due to a remote close or an unrecoverable transmission error.
+Once a stream has switched to non-readable mode, it MUST NOT transition
+back to readable mode.
+
+If this stream is a `DuplexStreamInterface`, you should also notice
+how the writable side of the stream also implements an `isWritable()`
+method. Unless this is a half-open duplex stream, they SHOULD usually
+have the same return value.
+
+#### pause()
+
+The `pause(): void` method can be used to
+pause reading incoming data events.
+
+Removes the data source file descriptor from the event loop. This
+allows you to throttle incoming data.
+
+Unless otherwise noted, a successfully opened stream SHOULD NOT start
+in paused state.
+
+Once the stream is paused, no futher `data` or `end` events SHOULD
+be emitted.
+
+```php
+$stream->pause();
+
+$stream->on('data', assertShouldNeverCalled());
+$stream->on('end', assertShouldNeverCalled());
+```
+
+This method is advisory-only, though generally not recommended, the
+stream MAY continue emitting `data` events.
+
+You can continue processing events by calling `resume()` again.
+
+Note that both methods can be called any number of times, in particular
+calling `pause()` more than once SHOULD NOT have any effect.
+
+See also `resume()`.
+
+#### resume()
+
+The `resume(): void` method can be used to
+resume reading incoming data events.
+
+Re-attach the data source after a previous `pause()`.
+
+```php
+$stream->pause();
+
+$loop->addTimer(1.0, function () use ($stream) {
+    $stream->resume();
+});
+```
+
+Note that both methods can be called any number of times, in particular
+calling `resume()` without a prior `pause()` SHOULD NOT have any effect.
+ 
+See also `pause()`.
+
+#### pipe()
+
+The `pipe(WritableStreamInterface $dest, array $options = [])` method can be used to
+pipe all the data from this readable source into the given writable destination.
+
+Automatically sends all incoming data to the destination.
+Automatically throttles the source based on what the destination can handle.
+
+```php
+$source->pipe($dest);
+```
+
+Similarly, you can also pipe an instance implementing `DuplexStreamInterface`
+into itself in order to write back all the data that is received.
+This may be a useful feature for a TCP/IP echo service:
+
+```php
+$connection->pipe($connection);
+```
+
+This method returns the destination stream as-is, which can be used to
+set up chains of piped streams:
+
+```php
+$source->pipe($decodeGzip)->pipe($filterBadWords)->pipe($dest);
+```
+
+By default, this will call `end()` on the destination stream once the
+source stream emits an `end` event. This can be disabled like this:
+
+```php
+$source->pipe($dest, array('end' => false));
+```
+
+Note that this only applies to the `end` event.
+If an `error` or explicit `close` event happens on the source stream,
+you'll have to manually close the destination stream:
+
+```php
+$source->pipe($dest);
+$source->on('close', function () use ($dest) {
+    $dest->end('BYE!');
+});
+```
+
+If the source stream is not readable (closed state), then this is a NO-OP.
+
+```php
+$source->close();
+$source->pipe($dest); // NO-OP
+```
+
+If the destinantion stream is not writable (closed state), then this will simply
+throttle (pause) the source stream:
+
+```php
+$dest->close();
+$source->pipe($dest); // calls $source->pause()
+```
+
+Similarly, if the destination stream is closed while the pipe is still
+active, it will also throttle (pause) the source stream:
+
+```php
+$source->pipe($dest);
+$dest->close(); // calls $source->pause()
+```
+
+Once the pipe is set up successfully, the destination stream MUST emit
+a `pipe` event with this source stream an event argument.
+
+#### close()
+
+The `close(): void` method can be used to
+close the stream (forcefully).
+
+This method can be used to (forcefully) close the stream.
+
+```php
+$stream->close();
+```
+
+Once the stream is closed, it SHOULD emit a `close` event.
+Note that this event SHOULD NOT be emitted more than once, in particular
+if this method is called multiple times.
+
+After calling this method, the stream MUST switch into a non-readable
+mode, see also `isReadable()`.
+This means that no further `data` or `end` events SHOULD be emitted.
+
+```php
+$stream->close();
+assert($stream->isReadable() === false);
+
+$stream->on('data', assertNeverCalled());
+$stream->on('end', assertNeverCalled());
+```
+
+If this stream is a `DuplexStreamInterface`, you should also notice
+how the writable side of the stream also implements a `close()` method.
+In other words, after calling this method, the stream MUST switch into
+non-writable AND non-readable mode, see also `isWritable()`.
+Note that this method should not be confused with the `end()` method.
+
+### WritableStreamInterface
+
+The `WritableStreamInterface` is responsible for providing an interface for
+write-only streams and the writable side of duplex streams.
+
+Besides defining a few methods, this interface also implements the
+`EventEmitterInterface` which allows you to react to certain events.
+
+The event callback functions MUST be a valid `callable` that obeys strict
+parameter definitions and MUST accept event parameters exactly as documented.
+The event callback functions MUST NOT throw an `Exception`.
+The return value of the event callback functions will be ignored and has no
+effect, so for performance reasons you're recommended to not return any
+excessive data structures.
+
+Every implementation of this interface MUST follow these event semantics in
+order to be considered a well-behaving stream.
+
+> Note that higher-level implementations of this interface may choose to
+  define additional events with dedicated semantics not defined as part of
+  this low-level stream specification. Conformance with these event semantics
+  is out of scope for this interface, so you may also have to refer to the
+  documentation of such a higher-level implementation.
+
+#### drain event
+
+The `drain` event will be emitted whenever the write buffer became full
+previously and is now ready to accept more data.
+
+```php
+$stream->on('drain', function () use ($stream) {
+    echo 'Stream is now ready to accept more data';
+});
+```
+
+This event SHOULD be emitted once every time the buffer became full
+previously and is now ready to accept more data.
+In other words, this event MAY be emitted any number of times, which may
+be zero times if the buffer never became full in the first place.
+This event SHOULD NOT be emitted if the buffer has not become full
+previously.
+
+This event is mostly used internally, see also `write()` for more details.
+
+#### pipe event
+
+The `pipe` event will be emitted whenever a readable stream is `pipe()`d
+into this stream.
+The event receives a single `ReadableStreamInterface` argument for the
+source stream.
+
+```php
+$stream->on('pipe', function (ReadableStreamInterface $source) use ($stream) {
+    echo 'Now receiving piped data';
+
+    // explicitly close target if source emits an error
+    $source->on('error', function () use ($stream) {
+        $stream->close();
+    });
+});
+
+$source->pipe($stream);
+```
+
+This event MUST be emitted once for each readable stream that is
+successfully piped into this destination stream.
+In other words, this event MAY be emitted any number of times, which may
+be zero times if no stream is ever piped into this stream.
+This event MUST NOT be emitted if either the source is not readable
+(closed already) or this destination is not writable (closed already).
+
+This event is mostly used internally, see also `pipe()` for more details.
+
+#### error event
+
+The `error` event will be emitted once a fatal error occurs, usually while
+trying to write to this stream.
+The event receives a single `Exception` argument for the error instance.
+
+```php
+$stream->on('error', function (Exception $e) {
+    echo 'Error: ' . $e->getMessage() . PHP_EOL;
+});
+```
+
+This event SHOULD be emitted once the stream detects a fatal error, such
+as a fatal transmission error.
+It SHOULD NOT be emitted after a previous `error` or `close` event.
+It MUST NOT be emitted if this is not a fatal error condition, such as
+a temporary network issue that did not cause any data to be lost.
+
+After the stream errors, it MUST close the stream and SHOULD thus be
+followed by a `close` event and then switch to non-writable mode, see
+also `close()` and `isWritable()`.
+
+Many common streams (such as a TCP/IP connection or a file-based stream)
+only deal with data transmission and may choose
+to only emit this for a fatal transmission error once and will then
+close (terminate) the stream in response.
+
+If this stream is a `DuplexStreamInterface`, you should also notice
+how the readable side of the stream also implements an `error` event.
+In other words, an error may occur while either reading or writing the
+stream which should result in the same error processing.
+
+#### close event
+
+The `close` event will be emitted once the stream closes (terminates).
+
+```php
+$stream->on('close', function () {
+    echo 'CLOSED';
+});
+```
+
+This event SHOULD be emitted once or never at all, depending on whether
+the stream ever terminates.
+It SHOULD NOT be emitted after a previous `close` event.
+
+After the stream is closed, it MUST switch to non-writable mode,
+see also `isWritable()`.
+
+This event SHOULD be emitted whenever the stream closes, irrespective of
+whether this happens implicitly due to an unrecoverable error or
+explicitly when either side closes the stream.
+
+Many common streams (such as a TCP/IP connection or a file-based stream)
+will likely choose to emit this event after flushing the buffer from
+the `end()` method, after receiving a *successful* `end` event or after
+a fatal transmission `error` event.
+
+If this stream is a `DuplexStreamInterface`, you should also notice
+how the readable side of the stream also implements a `close` event.
+In other words, after receiving this event, the stream MUST switch into
+non-writable AND non-readable mode, see also `isReadable()`.
+Note that this event should not be confused with the `end` event.
+
+#### isWritable()
+
+The `isWritable(): bool` method can be used to
+check whether this stream is in a writable state (not closed already).
+
+This method can be used to check if the stream still accepts writing
+any data or if it is ended or closed already.
+Writing any data to a non-writable stream is a NO-OP:
+
+```php
+assert($stream->isWritable() === false);
+
+$stream->write('end'); // NO-OP
+$stream->end('end'); // NO-OP
+```
+
+A successfully opened stream always MUST start in writable mode.
+
+Once the stream ends or closes, it MUST switch to non-writable mode.
+This can happen any time, explicitly through `end()` or `close()` or
+implicitly due to a remote close or an unrecoverable transmission error.
+Once a stream has switched to non-writable mode, it MUST NOT transition
+back to writable mode.
+
+If this stream is a `DuplexStreamInterface`, you should also notice
+how the readable side of the stream also implements an `isReadable()`
+method. Unless this is a half-open duplex stream, they SHOULD usually
+have the same return value.
+
+#### write()
+
+The `write(mixed $data): bool` method can be used to
+write some data into the stream.
+
+A successful write MUST be confirmed with a boolean `true`, which means
+that either the data was written (flushed) immediately or is buffered and
+scheduled for a future write. Note that this interface gives you no
+control over explicitly flushing the buffered data, as finding the
+appropriate time for this is beyond the scope of this interface and left
+up to the implementation of this interface.
+
+Many common streams (such as a TCP/IP connection or file-based stream)
+may choose to buffer all given data and schedule a future flush by using
+an underlying EventLoop to check when the resource is actually writable.
+
+If a stream cannot handle writing (or flushing) the data, it SHOULD emit
+an `error` event and MAY `close()` the stream if it can not recover from
+this error.
+
+If the internal buffer is full after adding `$data`, then `write()`
+SHOULD return `false`, indicating that the caller should stop sending
+data until the buffer drains.
+The stream SHOULD send a `drain` event once the buffer is ready to accept
+more data.
+
+Similarly, if the the stream is not writable (already in a closed state)
+it MUST NOT process the given `$data` and SHOULD return `false`,
+indicating that the caller should stop sending data.
+
+The given `$data` argument MAY be of mixed type, but it's usually
+recommended it SHOULD be a `string` value or MAY use a type that allows
+representation as a `string` for maximum compatibility.
+
+Many common streams (such as a TCP/IP connection or a file-based stream)
+will only accept the raw (binary) payload data that is transferred over
+the wire as chunks of `string` values.
+
+Due to the stream-based nature of this, the sender may send any number
+of chunks with varying sizes. There are no guarantees that these chunks
+will be received with the exact same framing the sender intended to send.
+In other words, many lower-level protocols (such as TCP/IP) transfer the
+data in chunks that may be anywhere between single-byte values to several
+dozens of kilobytes. You may want to apply a higher-level protocol to
+these low-level data chunks in order to achieve proper message framing.
+
+#### end()
+
+The `end(mixed $data = null): void` method can be used to
+successfully end the stream (after optionally sending some final data).
+
+This method can be used to successfully end the stream, i.e. close
+the stream after sending out all data that is currently buffered.
+
+```php
+$stream->write('hello');
+$stream->write('world');
+$stream->end();
+```
+
+If there's no data currently buffered and nothing to be flushed, then
+this method MAY `close()` the stream immediately.
+
+If there's still data in the buffer that needs to be flushed first, then
+this method SHOULD try to write out this data and only then `close()`
+the stream.
+Once the stream is closed, it SHOULD emit a `close` event.
+
+Note that this interface gives you no control over explicitly flushing
+the buffered data, as finding the appropriate time for this is beyond the
+scope of this interface and left up to the implementation of this
+interface.
+
+Many common streams (such as a TCP/IP connection or file-based stream)
+may choose to buffer all given data and schedule a future flush by using
+an underlying EventLoop to check when the resource is actually writable.
+
+You can optionally pass some final data that is written to the stream
+before ending the stream. If a non-`null` value is given as `$data`, then
+this method will behave just like calling `write($data)` before ending
+with no data.
+
+```php
+// shorter version
+$stream->end('bye');
+
+// same as longer version
+$stream->write('bye');
+$stream->end();
+```
+
+After calling this method, the stream MUST switch into a non-writable
+mode, see also `isWritable()`.
+This means that no further writes are possible, so any additional
+`write()` or `end()` calls have no effect.
+
+```php
+$stream->end();
+assert($stream->isWritable() === false);
+
+$stream->write('nope'); // NO-OP
+$stream->end(); // NO-OP
+```
+
+If this stream is a `DuplexStreamInterface`, calling this method SHOULD
+also end its readable side, unless the stream supports half-open mode.
+In other words, after calling this method, these streams SHOULD switch
+into non-writable AND non-readable mode, see also `isReadable()`.
+This implies that in this case, the stream SHOULD NOT emit any `data`
+or `end` events anymore.
+Streams MAY choose to use the `pause()` method logic for this, but
+special care may have to be taken to ensure a following call to the
+`resume()` method SHOULD NOT continue emitting readable events.
+
+Note that this method should not be confused with the `close()` method.
+
+#### close()
+
+The `close(): void` method can be used to
+close the stream (forcefully).
+
+This method can be used to forcefully close the stream, i.e. close
+the stream without waiting for any buffered data to be flushed.
+If there's still data in the buffer, this data SHOULD be discarded.
+
+```php
+$stream->close();
+```
+
+Once the stream is closed, it SHOULD emit a `close` event.
+Note that this event SHOULD NOT be emitted more than once, in particular
+if this method is called multiple times.
+
+After calling this method, the stream MUST switch into a non-writable
+mode, see also `isWritable()`.
+This means that no further writes are possible, so any additional
+`write()` or `end()` calls have no effect.
+
+```php
+$stream->close();
+assert($stream->isWritable() === false);
+
+$stream->write('nope'); // NO-OP
+$stream->end(); // NO-OP
+```
+
+Note that this method should not be confused with the `end()` method.
+Unlike the `end()` method, this method does not take care of any existing
+buffers and simply discards any buffer contents.
+Likewise, this method may also be called after calling `end()` on a
+stream in order to stop waiting for the stream to flush its final data.
+
+```php
+$stream->end();
+$loop->addTimer(1.0, function () use ($stream) {
+    $stream->close();
+});
+```
+
+If this stream is a `DuplexStreamInterface`, you should also notice
+how the readable side of the stream also implements a `close()` method.
+In other words, after calling this method, the stream MUST switch into
+non-writable AND non-readable mode, see also `isReadable()`.
+
+### DuplexStreamInterface
+
+The `DuplexStreamInterface` is responsible for providing an interface for
+duplex streams (both readable and writable).
+
+It builds on top of the existing interfaces for readable and writable streams
+and follows the exact same method and event semantics.
+If you're new to this concept, you should look into the
+`ReadableStreamInterface` and `WritableStreamInterface` first.
+
+Besides defining a few methods, this interface also implements the
+`EventEmitterInterface` which allows you to react to the same events defined
+on the `ReadbleStreamInterface` and `WritableStreamInterface`.
+
+The event callback functions MUST be a valid `callable` that obeys strict
+parameter definitions and MUST accept event parameters exactly as documented.
+The event callback functions MUST NOT throw an `Exception`.
+The return value of the event callback functions will be ignored and has no
+effect, so for performance reasons you're recommended to not return any
+excessive data structures.
+
+Every implementation of this interface MUST follow these event semantics in
+order to be considered a well-behaving stream.
+
+> Note that higher-level implementations of this interface may choose to
+  define additional events with dedicated semantics not defined as part of
+  this low-level stream specification. Conformance with these event semantics
+  is out of scope for this interface, so you may also have to refer to the
+  documentation of such a higher-level implementation.
+
+See also [`ReadableStreamInterface`](#readablestreaminterface) and
+[`WritableStreamInterface`](#writablestreaminterface) for more details.
+
+## Creating streams
+
+ReactPHP uses the concept of "streams" throughout its ecosystem, so that
+many higher-level consumers of this package only deal with
+[stream usage](#stream-usage).
+This implies that stream instances are most often created within some
+higher-level components and many consumers never actually have to deal with
+creating a stream instance.
+
+* Use [react/socket](https://github.com/reactphp/socket)
+  if you want to accept incoming or establish outgoing plaintext TCP/IP or
+  secure TLS socket connection streams.
+* Use [react/http](https://github.com/reactphp/http)
+  if you want to receive an incoming HTTP request body streams.
+* Use [react/child-process](https://github.com/reactphp/child-process)
+  if you want to communicate with child processes via process pipes such as
+  STDIN, STDOUT, STDERR etc.
+* Use experimental [react/filesystem](https://github.com/reactphp/filesystem)
+  if you want to read from / write to the filesystem.
+* See also the last chapter for [more real-world applications](#more).
+
+However, if you are writing a lower-level component or want to create a stream
+instance from a stream resource, then the following chapter is for you.
+
+> Note that the following examples use `fopen()` and `stream_socket_client()`
+  for illustration purposes only.
+  These functions SHOULD NOT be used in a truly async program because each call
+  may take several seconds to complete and would block the EventLoop otherwise.
+  Additionally, the `fopen()` call will return a file handle on some platforms
+  which may or may not be supported by all EventLoop implementations.
+  As an alternative, you may want to use higher-level libraries listed above.
+
+### ReadableResourceStream
+
+The `ReadableResourceStream` is a concrete implementation of the
+[`ReadableStreamInterface`](#readablestreaminterface) for PHP's stream resources.
+
+This can be used to represent a read-only resource like a file stream opened in
+readable mode or a stream such as `STDIN`:
+
+```php
+$stream = new ReadableResourceStream(STDIN, $loop);
+$stream->on('data', function ($chunk) {
+    echo $chunk;
+});
+$stream->on('end', function () {
+    echo 'END';
+});
+```
+
+See also [`ReadableStreamInterface`](#readablestreaminterface) for more details.
+
+The first parameter given to the constructor MUST be a valid stream resource
+that is opened in reading mode (e.g. `fopen()` mode `r`).
+Otherwise, it will throw an `InvalidArgumentException`:
+
+```php
+// throws InvalidArgumentException
+$stream = new ReadableResourceStream(false, $loop);
+```
+
+See also the [`DuplexResourceStream`](#readableresourcestream) for read-and-write
+stream resources otherwise.
+
+Internally, this class tries to enable non-blocking mode on the stream resource
+which may not be supported for all stream resources.
+Most notably, this is not supported by pipes on Windows (STDIN etc.).
+If this fails, it will throw a `RuntimeException`:
+
+```php
+// throws RuntimeException on Windows
+$stream = new ReadableResourceStream(STDIN, $loop);
+```
+
+Once the constructor is called with a valid stream resource, this class will
+take care of the underlying stream resource.
+You SHOULD only use its public API and SHOULD NOT interfere with the underlying
+stream resource manually.
+
+This class takes an optional `int|null $readChunkSize` parameter that controls
+the maximum buffer size in bytes to read at once from the stream.
+You can use a `null` value here in order to apply its default value.
+This value SHOULD NOT be changed unless you know what you're doing.
+This can be a positive number which means that up to X bytes will be read
+at once from the underlying stream resource. Note that the actual number
+of bytes read may be lower if the stream resource has less than X bytes
+currently available.
+This can be `-1` which means "read everything available" from the
+underlying stream resource.
+This should read until the stream resource is not readable anymore
+(i.e. underlying buffer drained), note that this does not neccessarily
+mean it reached EOF.
+
+```php
+$stream = new ReadableResourceStream(STDIN, $loop, 8192);
+```
+
+> PHP bug warning: If the PHP process has explicitly been started without a
+  `STDIN` stream, then trying to read from `STDIN` may return data from
+  another stream resource. This does not happen if you start this with an empty
+  stream like `php test.php < /dev/null` instead of `php test.php <&-`.
+  See [#81](https://github.com/reactphp/stream/issues/81) for more details.
+
+### WritableResourceStream
+
+The `WritableResourceStream` is a concrete implementation of the
+[`WritableStreamInterface`](#writablestreaminterface) for PHP's stream resources.
+
+This can be used to represent a write-only resource like a file stream opened in
+writable mode or a stream such as `STDOUT` or `STDERR`:
+
+```php
+$stream = new WritableResourceStream(STDOUT, $loop);
+$stream->write('hello!');
+$stream->end();
+```
+
+See also [`WritableStreamInterface`](#writablestreaminterface) for more details.
+
+The first parameter given to the constructor MUST be a valid stream resource
+that is opened for writing.
+Otherwise, it will throw an `InvalidArgumentException`:
+
+```php
+// throws InvalidArgumentException
+$stream = new WritableResourceStream(false, $loop);
+```
+
+See also the [`DuplexResourceStream`](#readableresourcestream) for read-and-write
+stream resources otherwise.
+
+Internally, this class tries to enable non-blocking mode on the stream resource
+which may not be supported for all stream resources.
+Most notably, this is not supported by pipes on Windows (STDOUT, STDERR etc.).
+If this fails, it will throw a `RuntimeException`:
+
+```php
+// throws RuntimeException on Windows
+$stream = new WritableResourceStream(STDOUT, $loop);
+```
+
+Once the constructor is called with a valid stream resource, this class will
+take care of the underlying stream resource.
+You SHOULD only use its public API and SHOULD NOT interfere with the underlying
+stream resource manually.
+
+Any `write()` calls to this class will not be performed instantly, but will
+be performed asynchronously, once the EventLoop reports the stream resource is
+ready to accept data.
+For this, it uses an in-memory buffer string to collect all outstanding writes.
+This buffer has a soft-limit applied which defines how much data it is willing
+to accept before the caller SHOULD stop sending further data.
+
+This class takes an optional `int|null $writeBufferSoftLimit` parameter that controls
+this maximum buffer size in bytes.
+You can use a `null` value here in order to apply its default value.
+This value SHOULD NOT be changed unless you know what you're doing.
+
+```php
+$stream = new WritableResourceStream(STDOUT, $loop, 8192);
+```
+
+This class takes an optional `int|null $writeChunkSize` parameter that controls
+this maximum buffer size in bytes to write at once to the stream.
+You can use a `null` value here in order to apply its default value.
+This value SHOULD NOT be changed unless you know what you're doing.
+This can be a positive number which means that up to X bytes will be written
+at once to the underlying stream resource. Note that the actual number
+of bytes written may be lower if the stream resource has less than X bytes
+currently available.
+This can be `-1` which means "write everything available" to the
+underlying stream resource.
+
+```php
+$stream = new WritableResourceStream(STDOUT, $loop, null, 8192);
+```
+
+See also [`write()`](#write) for more details.
+
+### DuplexResourceStream
+
+The `DuplexResourceStream` is a concrete implementation of the
+[`DuplexStreamInterface`](#duplexstreaminterface) for PHP's stream resources.
+
+This can be used to represent a read-and-write resource like a file stream opened
+in read and write mode mode or a stream such as a TCP/IP connection:
+
+```php
+$conn = stream_socket_client('tcp://google.com:80');
+$stream = new DuplexResourceStream($conn, $loop);
+$stream->write('hello!');
+$stream->end();
+```
+
+See also [`DuplexStreamInterface`](#duplexstreaminterface) for more details.
+
+The first parameter given to the constructor MUST be a valid stream resource
+that is opened for reading *and* writing.
+Otherwise, it will throw an `InvalidArgumentException`:
+
+```php
+// throws InvalidArgumentException
+$stream = new DuplexResourceStream(false, $loop);
+```
+
+See also the [`ReadableResourceStream`](#readableresourcestream) for read-only
+and the [`WritableResourceStream`](#writableresourcestream) for write-only
+stream resources otherwise.
+
+Internally, this class tries to enable non-blocking mode on the stream resource
+which may not be supported for all stream resources.
+Most notably, this is not supported by pipes on Windows (STDOUT, STDERR etc.).
+If this fails, it will throw a `RuntimeException`:
+
+```php
+// throws RuntimeException on Windows
+$stream = new DuplexResourceStream(STDOUT, $loop);
+```
+
+Once the constructor is called with a valid stream resource, this class will
+take care of the underlying stream resource.
+You SHOULD only use its public API and SHOULD NOT interfere with the underlying
+stream resource manually.
+
+This class takes an optional `int|null $readChunkSize` parameter that controls
+the maximum buffer size in bytes to read at once from the stream.
+You can use a `null` value here in order to apply its default value.
+This value SHOULD NOT be changed unless you know what you're doing.
+This can be a positive number which means that up to X bytes will be read
+at once from the underlying stream resource. Note that the actual number
+of bytes read may be lower if the stream resource has less than X bytes
+currently available.
+This can be `-1` which means "read everything available" from the
+underlying stream resource.
+This should read until the stream resource is not readable anymore
+(i.e. underlying buffer drained), note that this does not neccessarily
+mean it reached EOF.
+
+```php
+$conn = stream_socket_client('tcp://google.com:80');
+$stream = new DuplexResourceStream($conn, $loop, 8192);
+```
+
+Any `write()` calls to this class will not be performed instantly, but will
+be performed asynchronously, once the EventLoop reports the stream resource is
+ready to accept data.
+For this, it uses an in-memory buffer string to collect all outstanding writes.
+This buffer has a soft-limit applied which defines how much data it is willing
+to accept before the caller SHOULD stop sending further data.
+
+This class takes another optional `WritableStreamInterface|null $buffer` parameter
+that controls this write behavior of this stream.
+You can use a `null` value here in order to apply its default value.
+This value SHOULD NOT be changed unless you know what you're doing.
+
+If you want to change the write buffer soft limit, you can pass an instance of
+[`WritableResourceStream`](#writableresourcestream) like this:
+
+```php
+$conn = stream_socket_client('tcp://google.com:80');
+$buffer = new WritableResourceStream($conn, $loop, 8192);
+$stream = new DuplexResourceStream($conn, $loop, null, $buffer);
+```
+
+See also [`WritableResourceStream`](#writableresourcestream) for more details.
+
+### ThroughStream
+
+The `ThroughStream` implements the
+[`DuplexStreamInterface`](#duplexstreaminterface) and will simply pass any data
+you write to it through to its readable end.
+
+```php
+$through = new ThroughStream();
+$through->on('data', $this->expectCallableOnceWith('hello'));
+
+$through->write('hello');
+```
+
+Similarly, the [`end()` method](#end) will end the stream and emit an
+[`end` event](#end-event) and then [`close()`](#close-1) the stream.
+The [`close()` method](#close-1) will close the stream and emit a
+[`close` event](#close-event).
+Accordingly, this is can also be used in a [`pipe()`](#pipe) context like this:
+
+```php
+$through = new ThroughStream();
+$source->pipe($through)->pipe($dest);
+```
+
+Optionally, its constructor accepts any callable function which will then be
+used to *filter* any data written to it. This function receives a single data
+argument as passed to the writable side and must return the data as it will be
+passed to its readable end:
+
+```php
+$through = new ThroughStream('strtoupper');
+$source->pipe($through)->pipe($dest);
+```
+
+Note that this class makes no assumptions about any data types. This can be
+used to convert data, for example for transforming any structured data into
+a newline-delimited JSON (NDJSON) stream like this:
+
+```php
+$through = new ThroughStream(function ($data) {
+    return json_encode($data) . PHP_EOL;
+});
+$through->on('data', $this->expectCallableOnceWith("[2, true]\n"));
+
+$through->write(array(2, true));
+```
+
+The callback function is allowed to throw an `Exception`. In this case,
+the stream will emit an `error` event and then [`close()`](#close-1) the stream.
+
+```php
+$through = new ThroughStream(function ($data) {
+    if (!is_string($data)) {
+        throw new \UnexpectedValueException('Only strings allowed');
+    }
+    return $data;
+});
+$through->on('error', $this->expectCallableOnce()));
+$through->on('close', $this->expectCallableOnce()));
+$through->on('data', $this->expectCallableNever()));
+
+$through->write(2);
+```
+
+### CompositeStream
+
+The `CompositeStream` implements the
+[`DuplexStreamInterface`](#duplexstreaminterface) and can be used to create a
+single duplex stream from two individual streams implementing
+[`ReadableStreamInterface`](#readablestreaminterface) and
+[`WritableStreamInterface`](#writablestreaminterface) respectively.
+
+This is useful for some APIs which may require a single
+[`DuplexStreamInterface`](#duplexstreaminterface) or simply because it's often
+more convenient to work with a single stream instance like this:
+
+```php
+$stdin = new ReadableResourceStream(STDIN, $loop);
+$stdout = new WritableResourceStream(STDOUT, $loop);
+
+$stdio = new CompositeStream($stdin, $stdout);
+
+$stdio->on('data', function ($chunk) use ($stdio) {
+    $stdio->write('You said: ' . $chunk);
+});
+```
+
+This is a well-behaving stream which forwards all stream events from the
+underlying streams and forwards all streams calls to the underlying streams.
+
+If you `write()` to the duplex stream, it will simply `write()` to the
+writable side and return its status.
+
+If you `end()` the duplex stream, it will `end()` the writable side and will
+`pause()` the readable side.
+
+If you `close()` the duplex stream, both input streams will be closed.
+If either of the two input streams emits a `close` event, the duplex stream
+will also close.
+If either of the two input streams is already closed while constructing the
+duplex stream, it will `close()` the other side and return a closed stream.
+
+## Usage
+
+The following example can be used to pipe the contents of a source file into
+a destination file without having to ever read the whole file into memory:
+
+```php
+$loop = new React\EventLoop\StreamSelectLoop;
+
+$source = new React\Stream\ReadableResourceStream(fopen('source.txt', 'r'), $loop);
+$dest = new React\Stream\WritableResourceStream(fopen('destination.txt', 'w'), $loop);
+
+$source->pipe($dest);
+
+$loop->run();
+```
+
+> Note that this example uses `fopen()` for illustration purposes only.
+  This should not be used in a truly async program because the filesystem is
+  inherently blocking and each call could potentially take several seconds.
+  See also [creating streams](#creating-streams) for more sophisticated
+  examples.

+/**
+ * The `ReadableStreamInterface` is responsible for providing an interface for
+ * read-only streams and the readable side of duplex streams.
+ *
+ * Besides defining a few methods, this interface also implements the
+ * `EventEmitterInterface` which allows you to react to certain events:
+ *
+ * data event:
+ *     The `data` event will be emitted whenever some data was read/received
+ *     from this source stream.
+ *     The event receives a single mixed argument for incoming data.
+ *
+ *     ```php
+ *     $stream->on('data', function ($data) {
+ *         echo $data;
+ *     });
+ *     ```
+ *
+ *     This event MAY be emitted any number of times, which may be zero times if
+ *     this stream does not send any data at all.
+ *     It SHOULD not be emitted after an `end` or `close` event.
+ *
+ *     The given `$data` argument may be of mixed type, but it's usually
+ *     recommended it SHOULD be a `string` value or MAY use a type that allows
+ *     representation as a `string` for maximum compatibility.
+ *
+ *     Many common streams (such as a TCP/IP connection or a file-based stream)
+ *     will emit the raw (binary) payload data that is received over the wire as
+ *     chunks of `string` values.
+ *
+ *     Due to the stream-based nature of this, the sender may send any number
+ *     of chunks with varying sizes. There are no guarantees that these chunks
+ *     will be received with the exact same framing the sender intended to send.
+ *     In other words, many lower-level protocols (such as TCP/IP) transfer the
+ *     data in chunks that may be anywhere between single-byte values to several
+ *     dozens of kilobytes. You may want to apply a higher-level protocol to
+ *     these low-level data chunks in order to achieve proper message framing.
+ *
+ * end event:
+ *     The `end` event will be emitted once the source stream has successfully
+ *     reached the end of the stream (EOF).
+ *
+ *     ```php
+ *     $stream->on('end', function () {
+ *         echo 'END';
+ *     });
+ *     ```
+ *
+ *     This event SHOULD be emitted once or never at all, depending on whether
+ *     a successful end was detected.
+ *     It SHOULD NOT be emitted after a previous `end` or `close` event.
+ *     It MUST NOT be emitted if the stream closes due to a non-successful
+ *     end, such as after a previous `error` event.
+ *
+ *     After the stream is ended, it MUST switch to non-readable mode,
+ *     see also `isReadable()`.
+ *
+ *     This event will only be emitted if the *end* was reached successfully,
+ *     not if the stream was interrupted by an unrecoverable error or explicitly
+ *     closed. Not all streams know this concept of a "successful end".
+ *     Many use-cases involve detecting when the stream closes (terminates)
+ *     instead, in this case you should use the `close` event.
+ *     After the stream emits an `end` event, it SHOULD usually be followed by a
+ *     `close` event.
+ *
+ *     Many common streams (such as a TCP/IP connection or a file-based stream)
+ *     will emit this event if either the remote side closes the connection or
+ *     a file handle was successfully read until reaching its end (EOF).
+ *
+ *     Note that this event should not be confused with the `end()` method.
+ *     This event defines a successful end *reading* from a source stream, while
+ *     the `end()` method defines *writing* a successful end to a destination
+ *     stream.
+ *
+ * error event:
+ *     The `error` event will be emitted once a fatal error occurs, usually while
+ *     trying to read from this stream.
+ *     The event receives a single `Exception` argument for the error instance.
+ *
+ *     ```php
+ *     $stream->on('error', function (Exception $e) {
+ *         echo 'Error: ' . $e->getMessage() . PHP_EOL;
+ *     });
+ *     ```
+ *
+ *     This event SHOULD be emitted once the stream detects a fatal error, such
+ *     as a fatal transmission error or after an unexpected `data` or premature
+ *     `end` event.
+ *     It SHOULD NOT be emitted after a previous `error`, `end` or `close` event.
+ *     It MUST NOT be emitted if this is not a fatal error condition, such as
+ *     a temporary network issue that did not cause any data to be lost.
+ *
+ *     After the stream errors, it MUST close the stream and SHOULD thus be
+ *     followed by a `close` event and then switch to non-readable mode, see
+ *     also `close()` and `isReadable()`.
+ *
+ *     Many common streams (such as a TCP/IP connection or a file-based stream)
+ *     only deal with data transmission and do not make assumption about data
+ *     boundaries (such as unexpected `data` or premature `end` events).
+ *     In other words, many lower-level protocols (such as TCP/IP) may choose
+ *     to only emit this for a fatal transmission error once and will then
+ *     close (terminate) the stream in response.
+ *
+ *     If this stream is a `DuplexStreamInterface`, you should also notice
+ *     how the writable side of the stream also implements an `error` event.
+ *     In other words, an error may occur while either reading or writing the
+ *     stream which should result in the same error processing.
+ *
+ * close event:
+ *     The `close` event will be emitted once the stream closes (terminates).
+ *
+ *     ```php
+ *     $stream->on('close', function () {
+ *         echo 'CLOSED';
+ *     });
+ *     ```
+ *
+ *     This event SHOULD be emitted once or never at all, depending on whether
+ *     the stream ever terminates.
+ *     It SHOULD NOT be emitted after a previous `close` event.
+ *
+ *     After the stream is closed, it MUST switch to non-readable mode,
+ *     see also `isReadable()`.
+ *
+ *     Unlike the `end` event, this event SHOULD be emitted whenever the stream
+ *     closes, irrespective of whether this happens implicitly due to an
+ *     unrecoverable error or explicitly when either side closes the stream.
+ *     If you only want to detect a *successful* end, you should use the `end`
+ *     event instead.
+ *
+ *     Many common streams (such as a TCP/IP connection or a file-based stream)
+ *     will likely choose to emit this event after reading a *successful* `end`
+ *     event or after a fatal transmission `error` event.
+ *
+ *     If this stream is a `DuplexStreamInterface`, you should also notice
+ *     how the writable side of the stream also implements a `close` event.
+ *     In other words, after receiving this event, the stream MUST switch into
+ *     non-writable AND non-readable mode, see also `isWritable()`.
+ *     Note that this event should not be confused with the `end` event.
+ *
+ * The event callback functions MUST be a valid `callable` that obeys strict
+ * parameter definitions and MUST accept event parameters exactly as documented.
+ * The event callback functions MUST NOT throw an `Exception`.
+ * The return value of the event callback functions will be ignored and has no

+/**
+ * The `ThroughStream` implements the
+ * [`DuplexStreamInterface`](#duplexstreaminterface) and will simply pass any data
+ * you write to it through to its readable end.
+ *
+ * ```php
+ * $through = new ThroughStream();
+ * $through->on('data', $this->expectCallableOnceWith('hello'));
+ *
+ * $through->write('hello');
+ * ```
+ *
+ * Similarly, the [`end()` method](#end) will end the stream and emit an
+ * [`end` event](#end-event) and then [`close()`](#close-1) the stream.
+ * The [`close()` method](#close-1) will close the stream and emit a
+ * [`close` event](#close-event).
+ * Accordingly, this is can also be used in a [`pipe()`](#pipe) context like this:
+ *
+ * ```php
+ * $through = new ThroughStream();
+ * $source->pipe($through)->pipe($dest);
+ * ```
+ *
+ * Optionally, its constructor accepts any callable function which will then be
+ * used to *filter* any data written to it. This function receives a single data
+ * argument as passed to the writable side and must return the data as it will be
+ * passed to its readable end:
+ *
+ * ```php
+ * $through = new ThroughStream('strtoupper');
+ * $source->pipe($through)->pipe($dest);
+ * ```
+ *
+ * Note that this class makes no assumptions about any data types. This can be
+ * used to convert data, for example for transforming any structured data into
+ * a newline-delimited JSON (NDJSON) stream like this:
+ *
+ * ```php
+ * $through = new ThroughStream(function ($data) {
+ *     return json_encode($data) . PHP_EOL;
+ * });
+ * $through->on('data', $this->expectCallableOnceWith("[2, true]\n"));
+ *
+ * $through->write(array(2, true));
+ * ```
+ *
+ * The callback function is allowed to throw an `Exception`. In this case,
+ * the stream will emit an `error` event and then [`close()`](#close-1) the stream.
+ *
+ * ```php
+ * $through = new ThroughStream(function ($data) {
+ *     if (!is_string($data)) {
+ *         throw new \UnexpectedValueException('Only strings allowed');
+ *     }
+ *     return $data;
+ * });
+ * $through->on('error', $this->expectCallableOnce()));
+ * $through->on('close', $this->expectCallableOnce()));
+ * $through->on('data', $this->expectCallableNever()));
+ *

+/**
+ * The `WritableStreamInterface` is responsible for providing an interface for
+ * write-only streams and the writable side of duplex streams.
+ *
+ * Besides defining a few methods, this interface also implements the
+ * `EventEmitterInterface` which allows you to react to certain events:
+ *
+ * drain event:
+ *     The `drain` event will be emitted whenever the write buffer became full
+ *     previously and is now ready to accept more data.
+ *
+ *     ```php
+ *     $stream->on('drain', function () use ($stream) {
+ *         echo 'Stream is now ready to accept more data';
+ *     });
+ *     ```
+ *
+ *     This event SHOULD be emitted once every time the buffer became full
+ *     previously and is now ready to accept more data.
+ *     In other words, this event MAY be emitted any number of times, which may
+ *     be zero times if the buffer never became full in the first place.
+ *     This event SHOULD NOT be emitted if the buffer has not become full
+ *     previously.
+ *
+ *     This event is mostly used internally, see also `write()` for more details.
+ *
+ * pipe event:
+ *     The `pipe` event will be emitted whenever a readable stream is `pipe()`d
+ *     into this stream.
+ *     The event receives a single `ReadableStreamInterface` argument for the
+ *     source stream.
+ *
+ *     ```php
+ *     $stream->on('pipe', function (ReadableStreamInterface $source) use ($stream) {
+ *         echo 'Now receiving piped data';
+ *
+ *         // explicitly close target if source emits an error
+ *         $source->on('error', function () use ($stream) {
+ *             $stream->close();
+ *         });
+ *     });
+ *
+ *     $source->pipe($stream);
+ *     ```
+ *
+ *     This event MUST be emitted once for each readable stream that is
+ *     successfully piped into this destination stream.
+ *     In other words, this event MAY be emitted any number of times, which may
+ *     be zero times if no stream is ever piped into this stream.
+ *     This event MUST NOT be emitted if either the source is not readable
+ *     (closed already) or this destination is not writable (closed already).
+ *
+ *     This event is mostly used internally, see also `pipe()` for more details.
+ *
+ * error event:
+ *     The `error` event will be emitted once a fatal error occurs, usually while
+ *     trying to write to this stream.
+ *     The event receives a single `Exception` argument for the error instance.
+ *
+ *     ```php
+ *     $stream->on('error', function (Exception $e) {
+ *         echo 'Error: ' . $e->getMessage() . PHP_EOL;
+ *     });
+ *     ```
+ *
+ *     This event SHOULD be emitted once the stream detects a fatal error, such

+ *     It MUST NOT be emitted if this is not a fatal error condition, such as

+ *
+ *     After the stream errors, it MUST close the stream and SHOULD thus be
+ *     followed by a `close` event and then switch to non-writable mode, see
+ *     also `close()` and `isWritable()`.
+ *
+ *     Many common streams (such as a TCP/IP connection or a file-based stream)
+ *     only deal with data transmission and may choose
+ *     to only emit this for a fatal transmission error once and will then
+ *     close (terminate) the stream in response.
+ *
+ *     If this stream is a `DuplexStreamInterface`, you should also notice
+ *     how the readable side of the stream also implements an `error` event.
+ *     In other words, an error may occur while either reading or writing the
+ *     stream which should result in the same error processing.

+ * close event:
+ *     The `close` event will be emitted once the stream closes (terminates).

+ *     ```php
+ *     $stream->on('close', function () {
+ *         echo 'CLOSED';
+ *     });
+ *     ```
+ *
+ *     This event SHOULD be emitted once or never at all, depending on whether
+ *     the stream ever terminates.
+ *     It SHOULD NOT be emitted after a previous `close` event.
+ *
+ *     After the stream is closed, it MUST switch to non-writable mode,
+ *     see also `isWritable()`.
+ *
+ *     This event SHOULD be emitted whenever the stream closes, irrespective of
+ *     whether this happens implicitly due to an unrecoverable error or
+ *     explicitly when either side closes the stream.
+ *
+ *     Many common streams (such as a TCP/IP connection or a file-based stream)
+ *     will likely choose to emit this event after flushing the buffer from
+ *     the `end()` method, after receiving a *successful* `end` event or after
+ *     a fatal transmission `error` event.
+ *
+ *     If this stream is a `DuplexStreamInterface`, you should also notice
+ *     how the readable side of the stream also implements a `close` event.
+ *     In other words, after receiving this event, the stream MUST switch into
+ *     non-writable AND non-readable mode, see also `isReadable()`.
+ *     Note that this event should not be confused with the `end` event.
+ *
+ * The event callback functions MUST be a valid `callable` that obeys strict
+ * parameter definitions and MUST accept event parameters exactly as documented.
+ * The event callback functions MUST NOT throw an `Exception`.
+ * The return value of the event callback functions will be ignored and has no
+ * effect, so for performance reasons you're recommended to not return any
+ * excessive data structures.
+ *
+ * Every implementation of this interface MUST follow these event semantics in
+ * order to be considered a well-behaving stream.
+ *
+ * > Note that higher-level implementations of this interface may choose to
+ *   define additional events with dedicated semantics not defined as part of
+ *   this low-level stream specification. Conformance with these event semantics

+# PSR-7 Message Implementation
+
+This repository contains a partial [PSR-7](http://www.php-fig.org/psr/psr-7/)
+message implementation, several stream decorators, and some helpful
+functionality like query string parsing.  Currently missing
+ServerRequestInterface and UploadedFileInterface; a pull request for these features is welcome.
+
+
+# Stream implementation
+
+This package comes with a number of stream implementations and stream
+decorators.
+
+
+## AppendStream
+
+`RingCentral\Psr7\AppendStream`
+
+Reads from multiple streams, one after the other.
+
+```php
+use RingCentral\Psr7;
+
+$a = Psr7\stream_for('abc, ');
+$b = Psr7\stream_for('123.');
+$composed = new Psr7\AppendStream([$a, $b]);
+
+$composed->addStream(Psr7\stream_for(' Above all listen to me').
+
+echo $composed(); // abc, 123. Above all listen to me.
+```
+
+
+## BufferStream
+
+`RingCentral\Psr7\BufferStream`
+
+Provides a buffer stream that can be written to to fill a buffer, and read
+from to remove bytes from the buffer.
+
+This stream returns a "hwm" metadata value that tells upstream consumers
+what the configured high water mark of the stream is, or the maximum
+preferred size of the buffer.
+
+```php
+use RingCentral\Psr7;
+
+// When more than 1024 bytes are in the buffer, it will begin returning
+// false to writes. This is an indication that writers should slow down.
+$buffer = new Psr7\BufferStream(1024);
+```
+
+
+## CachingStream
+
+The CachingStream is used to allow seeking over previously read bytes on
+non-seekable streams. This can be useful when transferring a non-seekable
+entity body fails due to needing to rewind the stream (for example, resulting
+from a redirect). Data that is read from the remote stream will be buffered in
+a PHP temp stream so that previously read bytes are cached first in memory,
+then on disk.
+
+```php
+use RingCentral\Psr7;
+
+$original = Psr7\stream_for(fopen('http://www.google.com', 'r'));
+$stream = new Psr7\CachingStream($original);
+
+$stream->read(1024);
+echo $stream->tell();
+// 1024
+
+$stream->seek(0);
+echo $stream->tell();
+// 0
+```
+
+
+## DroppingStream
+
+`RingCentral\Psr7\DroppingStream`
+
+Stream decorator that begins dropping data once the size of the underlying
+stream becomes too full.
+
+```php
+use RingCentral\Psr7;
+
+// Create an empty stream
+$stream = Psr7\stream_for();
+
+// Start dropping data when the stream has more than 10 bytes
+$dropping = new Psr7\DroppingStream($stream, 10);
+
+$stream->write('01234567890123456789');
+echo $stream; // 0123456789
+```
+
+
+## FnStream
+
+`RingCentral\Psr7\FnStream`
+
+Compose stream implementations based on a hash of functions.
+
+Allows for easy testing and extension of a provided stream without needing to
+to create a concrete class for a simple extension point.
+
+```php
+
+use RingCentral\Psr7;
+
+$stream = Psr7\stream_for('hi');
+$fnStream = Psr7\FnStream::decorate($stream, [
+    'rewind' => function () use ($stream) {
+        echo 'About to rewind - ';
+        $stream->rewind();
+        echo 'rewound!';
+    }
+]);
+
+$fnStream->rewind();
+// Outputs: About to rewind - rewound!
+```
+
+
+## InflateStream
+
+`RingCentral\Psr7\InflateStream`
+
+Uses PHP's zlib.inflate filter to inflate deflate or gzipped content.
+
+This stream decorator skips the first 10 bytes of the given stream to remove
+the gzip header, converts the provided stream to a PHP stream resource,
+then appends the zlib.inflate filter. The stream is then converted back
+to a Guzzle stream resource to be used as a Guzzle stream.
+
+
+## LazyOpenStream
+
+`RingCentral\Psr7\LazyOpenStream`
+
+Lazily reads or writes to a file that is opened only after an IO operation
+take place on the stream.
+
+```php
+use RingCentral\Psr7;
+
+$stream = new Psr7\LazyOpenStream('/path/to/file', 'r');
+// The file has not yet been opened...
+
+echo $stream->read(10);
+// The file is opened and read from only when needed.
+```
+
+
+## LimitStream
+
+`RingCentral\Psr7\LimitStream`
+
+LimitStream can be used to read a subset or slice of an existing stream object.
+This can be useful for breaking a large file into smaller pieces to be sent in
+chunks (e.g. Amazon S3's multipart upload API).
+
+```php
+use RingCentral\Psr7;
+
+$original = Psr7\stream_for(fopen('/tmp/test.txt', 'r+'));
+echo $original->getSize();
+// >>> 1048576
+
+// Limit the size of the body to 1024 bytes and start reading from byte 2048
+$stream = new Psr7\LimitStream($original, 1024, 2048);
+echo $stream->getSize();
+// >>> 1024
+echo $stream->tell();
+// >>> 0
+```
+
+
+## MultipartStream
+
+`RingCentral\Psr7\MultipartStream`
+
+Stream that when read returns bytes for a streaming multipart or
+multipart/form-data stream.
+
+
+## NoSeekStream
+
+`RingCentral\Psr7\NoSeekStream`
+
+NoSeekStream wraps a stream and does not allow seeking.
+
+```php
+use RingCentral\Psr7;
+
+$original = Psr7\stream_for('foo');
+$noSeek = new Psr7\NoSeekStream($original);
+
+echo $noSeek->read(3);
+// foo
+var_export($noSeek->isSeekable());
+// false
+$noSeek->seek(0);
+var_export($noSeek->read(3));
+// NULL
+```
+
+
+## PumpStream
+
+`RingCentral\Psr7\PumpStream`
+
+Provides a read only stream that pumps data from a PHP callable.
+
+When invoking the provided callable, the PumpStream will pass the amount of
+data requested to read to the callable. The callable can choose to ignore
+this value and return fewer or more bytes than requested. Any extra data
+returned by the provided callable is buffered internally until drained using
+the read() function of the PumpStream. The provided callable MUST return
+false when there is no more data to read.
+
+
+## Implementing stream decorators
+
+Creating a stream decorator is very easy thanks to the
+`RingCentral\Psr7\StreamDecoratorTrait`. This trait provides methods that
+implement `Psr\Http\Message\StreamInterface` by proxying to an underlying
+stream. Just `use` the `StreamDecoratorTrait` and implement your custom
+methods.
+
+For example, let's say we wanted to call a specific function each time the last
+byte is read from a stream. This could be implemented by overriding the
+`read()` method.
+
+```php
+use Psr\Http\Message\StreamInterface;
+use RingCentral\Psr7\StreamDecoratorTrait;
+
+class EofCallbackStream implements StreamInterface
+{
+    use StreamDecoratorTrait;
+
+    private $callback;
+
+    public function __construct(StreamInterface $stream, callable $cb)
+    {
+        $this->stream = $stream;
+        $this->callback = $cb;
+    }
+
+    public function read($length)
+    {
+        $result = $this->stream->read($length);
+
+        // Invoke the callback when EOF is hit.
+        if ($this->eof()) {
+            call_user_func($this->callback);
+        }
+
+        return $result;
+    }
+}
+```
+
+This decorator could be added to any existing stream and used like so:
+
+```php
+use RingCentral\Psr7;
+
+$original = Psr7\stream_for('foo');
+
+$eofStream = new EofCallbackStream($original, function () {
+    echo 'EOF!';
+});
+
+$eofStream->read(2);
+$eofStream->read(1);
+// echoes "EOF!"
+$eofStream->seek(0);
+$eofStream->read(3);
+// echoes "EOF!"
+```
+
+
+## PHP StreamWrapper
+
+You can use the `RingCentral\Psr7\StreamWrapper` class if you need to use a
+PSR-7 stream as a PHP stream resource.
+
+Use the `RingCentral\Psr7\StreamWrapper::getResource()` method to create a PHP
+stream from a PSR-7 stream.
+
+```php
+use RingCentral\Psr7\StreamWrapper;
+
+$stream = RingCentral\Psr7\stream_for('hello!');
+$resource = StreamWrapper::getResource($stream);
+echo fread($resource, 6); // outputs hello!
+```
+
+
+# Function API
+
+There are various functions available under the `RingCentral\Psr7` namespace.
+
+
+## `function str`
+
+`function str(MessageInterface $message)`
+
+Returns the string representation of an HTTP message.
+
+```php
+$request = new RingCentral\Psr7\Request('GET', 'http://example.com');
+echo RingCentral\Psr7\str($request);
+```
+
+
+## `function uri_for`
+
+`function uri_for($uri)`
+
+This function accepts a string or `Psr\Http\Message\UriInterface` and returns a
+UriInterface for the given value. If the value is already a `UriInterface`, it
+is returned as-is.
+
+```php
+$uri = RingCentral\Psr7\uri_for('http://example.com');
+assert($uri === RingCentral\Psr7\uri_for($uri));
+```
+
+
+## `function stream_for`
+
+`function stream_for($resource = '', array $options = [])`
+
+Create a new stream based on the input type.
+
+Options is an associative array that can contain the following keys:
+
+* - metadata: Array of custom metadata.
+* - size: Size of the stream.
+
+This method accepts the following `$resource` types:
+
+- `Psr\Http\Message\StreamInterface`: Returns the value as-is.
+- `string`: Creates a stream object that uses the given string as the contents.
+- `resource`: Creates a stream object that wraps the given PHP stream resource.
+- `Iterator`: If the provided value implements `Iterator`, then a read-only
+  stream object will be created that wraps the given iterable. Each time the
+  stream is read from, data from the iterator will fill a buffer and will be
+  continuously called until the buffer is equal to the requested read size.
+  Subsequent read calls will first read from the buffer and then call `next`
+  on the underlying iterator until it is exhausted.
+- `object` with `__toString()`: If the object has the `__toString()` method,
+  the object will be cast to a string and then a stream will be returned that
+  uses the string value.
+- `NULL`: When `null` is passed, an empty stream object is returned.
+- `callable` When a callable is passed, a read-only stream object will be
+  created that invokes the given callable. The callable is invoked with the
+  number of suggested bytes to read. The callable can return any number of
+  bytes, but MUST return `false` when there is no more data to return. The
+  stream object that wraps the callable will invoke the callable until the
+  number of requested bytes are available. Any additional bytes will be
+  buffered and used in subsequent reads.
+
+```php
+$stream = RingCentral\Psr7\stream_for('foo');
+$stream = RingCentral\Psr7\stream_for(fopen('/path/to/file', 'r'));
+
+$generator function ($bytes) {
+    for ($i = 0; $i < $bytes; $i++) {
+        yield ' ';
+    }
+}
+
+$stream = RingCentral\Psr7\stream_for($generator(100));
+```
+
+
+## `function parse_header`
+
+`function parse_header($header)`
+
+Parse an array of header values containing ";" separated data into an array of
+associative arrays representing the header key value pair data of the header.
+When a parameter does not contain a value, but just contains a key, this
+function will inject a key with a '' string value.
+
+
+## `function normalize_header`
+
+`function normalize_header($header)`
+
+Converts an array of header values that may contain comma separated headers
+into an array of headers with no comma separated values.
+
+
+## `function modify_request`
+
+`function modify_request(RequestInterface $request, array $changes)`
+
+Clone and modify a request with the given changes. This method is useful for
+reducing the number of clones needed to mutate a message.
+
+The changes can be one of:
+
+- method: (string) Changes the HTTP method.
+- set_headers: (array) Sets the given headers.
+- remove_headers: (array) Remove the given headers.
+- body: (mixed) Sets the given body.
+- uri: (UriInterface) Set the URI.
+- query: (string) Set the query string value of the URI.
+- version: (string) Set the protocol version.
+
+
+## `function rewind_body`
+
+`function rewind_body(MessageInterface $message)`
+
+Attempts to rewind a message body and throws an exception on failure. The body
+of the message will only be rewound if a call to `tell()` returns a value other
+than `0`.
+
+
+## `function try_fopen`
+
+`function try_fopen($filename, $mode)`
+
+Safely opens a PHP stream resource using a filename.
+
+When fopen fails, PHP normally raises a warning. This function adds an error
+handler that checks for errors and throws an exception instead.
+
+
+## `function copy_to_string`
+
+`function copy_to_string(StreamInterface $stream, $maxLen = -1)`
+
+Copy the contents of a stream into a string until the given number of bytes
+have been read.
+
+
+## `function copy_to_stream`
+
+`function copy_to_stream(StreamInterface $source, StreamInterface $dest, $maxLen = -1)`
+
+Copy the contents of a stream into another stream until the given number of
+bytes have been read.
+
+
+## `function hash`
+
+`function hash(StreamInterface $stream, $algo, $rawOutput = false)`
+
+Calculate a hash of a Stream. This method reads the entire stream to calculate
+a rolling hash (based on PHP's hash_init functions).
+
+
+## `function readline`
+
+`function readline(StreamInterface $stream, $maxLength = null)`
+
+Read a line from the stream up to the maximum allowed buffer length.
+
+
+## `function parse_request`
+
+`function parse_request($message)`
+
+Parses a request message string into a request object.
+
+
+## `function parse_server_request`
+
+`function parse_server_request($message, array $serverParams = array())`
+
+Parses a request message string into a server-side request object.
+
+
+## `function parse_response`
+
+`function parse_response($message)`
+
+Parses a response message string into a response object.
+
+
+## `function parse_query`
+
+`function parse_query($str, $urlEncoding = true)`
+
+Parse a query string into an associative array.
+
+If multiple values are found for the same key, the value of that key value pair
+will become an array. This function does not parse nested PHP style arrays into
+an associative array (e.g., `foo[a]=1&foo[b]=2` will be parsed into
+`['foo[a]' => '1', 'foo[b]' => '2']`).
+
+
+## `function build_query`
+
+`function build_query(array $params, $encoding = PHP_QUERY_RFC3986)`
+
+Build a query string from an array of key value pairs.
+
+This function can use the return value of parseQuery() to build a query string.
+This function does not modify the provided keys when an array is encountered
+(like http_build_query would).
+
+
+## `function mimetype_from_filename`
+
+`function mimetype_from_filename($filename)`
+
+Determines the mimetype of a file by looking at its extension.
+
+
+## `function mimetype_from_extension`
+
+`function mimetype_from_extension($extension)`
+
+Maps a file extensions to a mimetype.
+
+
+# Static URI methods
+
+The `RingCentral\Psr7\Uri` class has several static methods to manipulate URIs.
+
+
+## `RingCentral\Psr7\Uri::removeDotSegments`
+
+`public static function removeDotSegments($path) -> UriInterface`
+
+Removes dot segments from a path and returns the new path.
+
+See http://tools.ietf.org/html/rfc3986#section-5.2.4
+
+
+## `RingCentral\Psr7\Uri::resolve`
+
+`public static function resolve(UriInterface $base, $rel) -> UriInterface`
+
+Resolve a base URI with a relative URI and return a new URI.
+
+See http://tools.ietf.org/html/rfc3986#section-5
+
+
+## `RingCentral\Psr7\Uri::withQueryValue`
+
+`public static function withQueryValue(UriInterface $uri, $key, $value) -> UriInterface`
+
+Create a new URI with a specific query string value.
+
+Any existing query string values that exactly match the provided key are
+removed and replaced with the given key value pair.
+
+Note: this function will convert "=" to "%3D" and "&" to "%26".
+
+
+## `RingCentral\Psr7\Uri::withoutQueryValue`
+
+`public static function withoutQueryValue(UriInterface $uri, $key, $value) -> UriInterface`
+
+Create a new URI with a specific query string value removed.
+
+Any existing query string values that exactly match the provided key are
+removed.
+
+Note: this function will convert "=" to "%3D" and "&" to "%26".
+
+
+## `RingCentral\Psr7\Uri::fromParts`
+
+`public static function fromParts(array $parts) -> UriInterface`
+
+Create a `RingCentral\Psr7\Uri` object from a hash of `parse_url` parts.
+

+# fbns-react
+
+A PHP client for the FBNS built on top of ReactPHP.
+
+## Requirements
+
+You need to install the [GMP extension](http://php.net/manual/en/book.gmp.php) to be able to run this code on x86 PHP builds.
+
+## Installation
+
+```sh
+composer require valga/fbns-react
+```
+
+## Basic Usage
+
+```php
+// Set up a FBNS client.
+$loop = \React\EventLoop\Factory::create();
+$client = new \Fbns\Client\Lite($loop);
+
+// Read saved credentials from a storage.
+$auth = new \Fbns\Client\Auth\DeviceAuth();
+try {
+    $auth->read($storage->get('fbns_auth'));
+} catch (\Exception $e) {
+}
+
+// Connect to a broker.
+$connection = new \Fbns\Client\Connection($deviceAuth, USER_AGENT);
+$client->connect(HOSTNAME, PORT, $connection);
+
+// Bind events.
+$client
+    ->on('connect', function (\Fbns\Client\Lite\ConnectResponsePacket $responsePacket) use ($client, $auth, $storage) {
+        // Update credentials and save them to a storage for future use.
+        try {
+            $auth->read($responsePacket->getAuth());
+            $storage->set('fbns_auth', $responsePacket->getAuth());
+        } catch (\Exception $e) {
+        }
+        
+        // Register an application.
+        $client->register(PACKAGE_NAME, APPLICATION_ID);
+    })
+    ->on('register', function (\Fbns\Client\Message\Register $message) use ($app) {
+        // Register received token with an application.
+        $app->registerPushToken($message->getToken());
+    })
+    ->on('push', function (\Fbns\Client\Message\Push $message) use ($app) {
+        // Handle received notification payload.
+        $app->handlePushNotification($message->getPayload());
+    });
+
+// Run main loop.
+$loop->run();
+```
+
+## Advanced Usage
+
+```php
+// Set up a proxy.
+$connector = new \React\Socket\Connector($loop);
+$proxy = new \Clue\React\HttpProxy('username:password@127.0.0.1:3128', $connector);
+
+// Disable SSL verification.
+$ssl = new \React\Socket\SecureConnector($proxy, $loop, ['verify_peer' => false, 'verify_peer_name' => false]);
+
+// Enable logging to stdout.
+$logger = new \Monolog\Logger('fbns');
+$logger->pushHandler(new \Monolog\Handler\StreamHandler('php://stdout', \Monolog\Logger::INFO));
+
+// Set up a client.
+$client = new \Fbns\Client\Lite($loop, $ssl, $logger);
+
+// Persistence.
+$client->on('disconnect', function () {
+    // Network connection has been closed. You can reestablish it if you want to.
+});
+$client->connect(HOSTNAME, PORT, $connection)
+    ->otherwise(function () {
+        // Connection attempt was unsuccessful, retry with an exponential backoff.
+    });
+```

+Winbox-Args
+===========
+
+[![Build Status](https://travis-ci.org/johnstevenson/winbox-args.svg?branch=master)](https://travis-ci.org/johnstevenson/winbox-args)
+[![Build status](https://ci.appveyor.com/api/projects/status/p4k75qqcyioj0mfl?svg=true)](https://ci.appveyor.com/project/johnstevenson/winbox-args)
+
+A PHP function to escape command-line arguments, which on Windows replaces `escapeshellarg` with a more robust method. Install from [Packagist][packagist] and use it like this:
+
+```php
+$escaped = Winbox\Args::escape($argument);
+```
+
+Alternatively, you can just [copy the code][function] into your own project (but please keep the license attribution and documentation link).
+
+### What it does
+The following transformations are made:
+
+* Double-quotes are escaped with a backslash, with any preceeding backslashes doubled up.
+* The argument is only enclosed in double-quotes if it contains whitespace or is empty.
+* Trailing backslashes are doubled up if the argument is enclosed in double-quotes.
+
+See [How Windows parses the command-line](https://github.com/johnstevenson/winbox-args/wiki/How-Windows-parses-the-command-line) if you would like to know why.
+
+By default, _cmd.exe_ meta characters are also escaped:
+
+* by caret-escaping the transformed argument (if it contains internal double-quotes or `%...%` syntax).
+* or by enclosing the argument in double-quotes.
+
+There are a couple limitations:
+
+1. If _cmd_ is started with _DelayedExpansion_ enabled, `!...!` syntax could expand environment variables.
+2. If the program name requires caret-escaping and contains whitespace, _cmd_ will not recognize it.
+
+See [How cmd.exe parses a command](https://github.com/johnstevenson/winbox-args/wiki/How-cmd.exe-parses-a-command) and [Implementing a solution](https://github.com/johnstevenson/winbox-args/wiki/Implementing-a-solution) for more information.
+
+### Is that it?
+Yup. An entire repo for a tiny function. However, it needs quite a lot of explanation because:
+
+* the command-line parsing rules in Windows are not immediately obvious.
+* PHP generally uses _cmd.exe_ to execute programs and this applies a different set of rules.
+* there is no simple solution.
+
+Full details explaining the different parsing rules, potential pitfalls and limitations can be found in the [Wiki][wiki].

+
+This package provides an asynchronous MQTT client built on the [React socket](https://github.com/reactphp/socket) library. All client methods return a promise which is fulfilled if the operation succeeded or rejected if the operation failed. Incoming messages of subscribed topics are delivered via the "message" event.
+
+## Install
+
+Via composer:
+
+``` bash
+$ composer require binsoul/net-mqtt-client-react
+```
+
+## Example
+
+Connect to a public broker and run forever.
+
+``` php

+# clue/http-proxy-react [![Build Status](https://travis-ci.org/clue/php-http-proxy-react.svg?branch=master)](https://travis-ci.org/clue/php-http-proxy-react)
+
+Async HTTP proxy connector, use any TCP/IP-based protocol through an HTTP
+CONNECT proxy server, built on top of [ReactPHP](https://reactphp.org).
+
+HTTP CONNECT proxy servers (also commonly known as "HTTPS proxy" or "SSL proxy")
+are commonly used to tunnel HTTPS traffic through an intermediary ("proxy"), to
+conceal the origin address (anonymity) or to circumvent address blocking
+(geoblocking). While many (public) HTTP CONNECT proxy servers often limit this
+to HTTPS port `443` only, this can technically be used to tunnel any
+TCP/IP-based protocol (HTTP, SMTP, IMAP etc.).
+This library provides a simple API to create these tunneled connection for you.
+Because it implements ReactPHP's standard
+[`ConnectorInterface`](https://github.com/reactphp/socket#connectorinterface),
+it can simply be used in place of a normal connector.
+This makes it fairly simple to add HTTP CONNECT proxy support to pretty much any
+existing higher-level protocol implementation.
+
+* **Async execution of connections** -
+  Send any number of HTTP CONNECT requests in parallel and process their
+  responses as soon as results come in.
+  The Promise-based design provides a *sane* interface to working with out of
+  bound responses and possible connection errors.
+* **Standard interfaces** -
+  Allows easy integration with existing higher-level components by implementing
+  ReactPHP's standard
+  [`ConnectorInterface`](https://github.com/reactphp/socket#connectorinterface).
+* **Lightweight, SOLID design** -
+  Provides a thin abstraction that is [*just good enough*](http://en.wikipedia.org/wiki/Principle_of_good_enough)
+  and does not get in your way.
+  Builds on top of well-tested components and well-established concepts instead of reinventing the wheel.
+* **Good test coverage** -
+  Comes with an automated tests suite and is regularly tested against actual proxy servers in the wild

+
+### Quickstart example
+
+The following example code demonstrates how this library can be used to send a
+secure HTTPS request to google.com through a local HTTP proxy server:
+
+```php
+$loop = React\EventLoop\Factory::create();
+
+$proxy = new ProxyConnector('127.0.0.1:8080', new Connector($loop));
+$connector = new Connector($loop, array(
+    'tcp' => $proxy,
+    'timeout' => 3.0,
+    'dns' => false
+));
+
+$connector->connect('tls://google.com:443')->then(function (ConnectionInterface $stream) {
+    $stream->write("GET / HTTP/1.1\r\nHost: google.com\r\nConnection: close\r\n\r\n");
+    $stream->on('data', function ($chunk) {
+        echo $chunk;
+    });
+}, 'printf');
+
+$loop->run();
+```
+
+See also the [examples](examples).
+
+## Usage
+
+### ProxyConnector
+
+The `ProxyConnector` is responsible for creating plain TCP/IP connections to
+any destination by using an intermediary HTTP CONNECT proxy.
+
+```
+[you] -> [proxy] -> [destination]
+```
+
+Its constructor simply accepts an HTTP proxy URL and a connector used to connect
+to the proxy server address:
+
+```php
+$connector = new Connector($loop);
+$proxy = new ProxyConnector('http://127.0.0.1:8080', $connector);
+```
+
+The proxy URL may or may not contain a scheme and port definition. The default
+port will be `80` for HTTP (or `443` for HTTPS), but many common HTTP proxy
+servers use custom ports (often the alternative HTTP port `8080`).
+In its most simple form, the given connector will be a
+[`\React\Socket\Connector`](https://github.com/reactphp/socket#connector) if you
+want to connect to a given IP address as above.
+
+This is the main class in this package.
+Because it implements ReactPHP's standard
+[`ConnectorInterface`](https://github.com/reactphp/socket#connectorinterface),
+it can simply be used in place of a normal connector.
+Accordingly, it provides only a single public method, the
+[`connect()`](https://github.com/reactphp/socket#connect) method.
+The `connect(string $uri): PromiseInterface<ConnectionInterface, Exception>`
+method can be used to establish a streaming connection.
+It returns a [Promise](https://github.com/reactphp/promise) which either
+fulfills with a [ConnectionInterface](https://github.com/reactphp/socket#connectioninterface)
+on success or rejects with an `Exception` on error.
+
+This makes it fairly simple to add HTTP CONNECT proxy support to pretty much any
+higher-level component:
+
+```diff
+- $client = new SomeClient($connector);
++ $proxy = new ProxyConnector('http://127.0.0.1:8080', $connector);
++ $client = new SomeClient($proxy);
+```
+
+#### Plain TCP connections
+
+HTTP CONNECT proxies are most frequently used to issue HTTPS requests to your destination.
+However, this is actually performed on a higher protocol layer and this
+connector is actually inherently a general-purpose plain TCP/IP connector.
+As documented above, you can simply invoke its `connect()` method to establish
+a streaming plain TCP/IP connection and use any higher level protocol like so:
+
+```php
+$proxy = new ProxyConnector('http://127.0.0.1:8080', $connector);
+
+$proxy->connect('tcp://smtp.googlemail.com:587')->then(function (ConnectionInterface $stream) {
+    $stream->write("EHLO local\r\n");
+    $stream->on('data', function ($chunk) use ($stream) {
+        echo $chunk;
+    });
+});
+```
+
+You can either use the `ProxyConnector` directly or you may want to wrap this connector
+in ReactPHP's [`Connector`](https://github.com/reactphp/socket#connector):
+
+```php
+$connector = new Connector($loop, array(
+    'tcp' => $proxy,
+    'dns' => false
+));
+
+$connector->connect('tcp://smtp.googlemail.com:587')->then(function (ConnectionInterface $stream) {
+    $stream->write("EHLO local\r\n");
+    $stream->on('data', function ($chunk) use ($stream) {
+        echo $chunk;
+    });
+});
+```
+
+Note that HTTP CONNECT proxies often restrict which ports one may connect to.
+Many (public) proxy servers do in fact limit this to HTTPS (443) only.
+
+#### Secure TLS connections
+
+This class can also be used if you want to establish a secure TLS connection
+(formerly known as SSL) between you and your destination, such as when using
+secure HTTPS to your destination site. You can simply wrap this connector in
+ReactPHP's [`Connector`](https://github.com/reactphp/socket#connector) or the
+low-level [`SecureConnector`](https://github.com/reactphp/socket#secureconnector):
+
+```php
+$proxy = new ProxyConnector('http://127.0.0.1:8080', $connector);
+$connector = new Connector($loop, array(
+    'tcp' => $proxy,
+    'dns' => false
+));
+
+$connector->connect('tls://smtp.googlemail.com:465')->then(function (ConnectionInterface $stream) {
+    $stream->write("EHLO local\r\n");
+    $stream->on('data', function ($chunk) use ($stream) {
+        echo $chunk;
+    });
+});
+```
+
+> Note how secure TLS connections are in fact entirely handled outside of
+  this HTTP CONNECT client implementation.
+
+#### Connection timeout
+
+By default, the `ProxyConnector` does not implement any timeouts for establishing remote
+connections.
+Your underlying operating system may impose limits on pending and/or idle TCP/IP
+connections, anywhere in a range of a few minutes to several hours.
+
+Many use cases require more control over the timeout and likely values much
+smaller, usually in the range of a few seconds only.
+
+You can use ReactPHP's [`Connector`](https://github.com/reactphp/socket#connector)
+or the low-level
+[`TimeoutConnector`](https://github.com/reactphp/socket#timeoutconnector)
+to decorate any given `ConnectorInterface` instance.
+It provides the same `connect()` method, but will automatically reject the
+underlying connection attempt if it takes too long:
+
+```php
+$connector = new Connector($loop, array(
+    'tcp' => $proxy,
+    'dns' => false,
+    'timeout' => 3.0
+));
+
+$connector->connect('tcp://google.com:80')->then(function ($stream) {
+    // connection succeeded within 3.0 seconds
+});
+```
+
+See also any of the [examples](examples).
+
+> Note how connection timeout is in fact entirely handled outside of this
+  HTTP CONNECT client implementation.
+
+#### DNS resolution
+
+By default, the `ProxyConnector` does not perform any DNS resolution at all and simply
+forwards any hostname you're trying to connect to the remote proxy server.
+The remote proxy server is thus responsible for looking up any hostnames via DNS
+(this default mode is thus called *remote DNS resolution*).
+
+As an alternative, you can also send the destination IP to the remote proxy
+server.
+In this mode you either have to stick to using IPs only (which is ofen unfeasable)
+or perform any DNS lookups locally and only transmit the resolved destination IPs
+(this mode is thus called *local DNS resolution*).
+
+The default *remote DNS resolution* is useful if your local `ProxyConnector` either can
+not resolve target hostnames because it has no direct access to the internet or
+if it should not resolve target hostnames because its outgoing DNS traffic might
+be intercepted.
+
+As noted above, the `ProxyConnector` defaults to using remote DNS resolution.
+However, wrapping the `ProxyConnector` in ReactPHP's
+[`Connector`](https://github.com/reactphp/socket#connector) actually
+performs local DNS resolution unless explicitly defined otherwise.
+Given that remote DNS resolution is assumed to be the preferred mode, all
+other examples explicitly disable DNS resoltion like this:
+
+```php
+$connector = new Connector($loop, array(
+    'tcp' => $proxy,
+    'dns' => false
+));
+```
+
+If you want to explicitly use *local DNS resolution*, you can use the following code:
+
+```php
+// set up Connector which uses Google's public DNS (8.8.8.8)
+$connector = Connector($loop, array(
+    'tcp' => $proxy,
+    'dns' => '8.8.8.8'
+));
+```
+
+> Note how local DNS resolution is in fact entirely handled outside of this
+  HTTP CONNECT client implementation.
+
+#### Authentication
+
+If your HTTP proxy server requires authentication, you may pass the username and
+password as part of the HTTP proxy URL like this:
+
+```php
+$proxy = new ProxyConnector('http://user:pass@127.0.0.1:8080', $connector);
+```
+
+Note that both the username and password must be percent-encoded if they contain
+special characters:
+
+```php
+$user = 'he:llo';
+$pass = 'p@ss';
+
+$proxy = new ProxyConnector(
+    rawurlencode($user) . ':' . rawurlencode($pass) . '@127.0.0.1:8080',
+    $connector
+);
+```
+
+> The authentication details will be used for basic authentication and will be
+  transferred in the `Proxy-Authorization` HTTP request header for each
+  connection attempt.
+  If the authentication details are missing or not accepted by the remote HTTP
+  proxy server, it is expected to reject each connection attempt with a
+  `407` (Proxy Authentication Required) response status code and an exception
+  error code of `SOCKET_EACCES` (13).
+
+#### Advanced secure proxy connections
+
+Note that communication between the client and the proxy is usually via an
+unencrypted, plain TCP/IP HTTP connection. Note that this is the most common
+setup, because you can still establish a TLS connection between you and the
+destination host as above.
+
+If you want to connect to a (rather rare) HTTPS proxy, you may want use the
+`https://` scheme (HTTPS default port 443) and use ReactPHP's
+[`Connector`](https://github.com/reactphp/socket#connector) or the low-level
+[`SecureConnector`](https://github.com/reactphp/socket#secureconnector)
+instance to create a secure connection to the proxy:
+
+```php
+$connector = new Connector($loop);
+$proxy = new ProxyConnector('https://127.0.0.1:443', $connector);
+
+$proxy->connect('tcp://smtp.googlemail.com:587');
+```
+
+#### Advanced Unix domain sockets
+
+HTTP CONNECT proxy servers support forwarding TCP/IP based connections and
+higher level protocols.
+In some advanced cases, it may be useful to let your HTTP CONNECT proxy server
+listen on a Unix domain socket (UDS) path instead of a IP:port combination.
+For example, this allows you to rely on file system permissions instead of
+having to rely on explicit [authentication](#authentication).
+
+You can simply use the `http+unix://` URI scheme like this:
+
+```php
+$proxy = new ProxyConnector('http+unix:///tmp/proxy.sock', $connector);
+
+$proxy->connect('tcp://google.com:80')->then(function (ConnectionInterface $stream) {
+    // connected…
+});
+```
+
+Similarly, you can also combine this with [authentication](#authentication)
+like this:
+
+```php
+$proxy = new ProxyConnector('http+unix://user:pass@/tmp/proxy.sock', $connector);
+```
+
+> Note that Unix domain sockets (UDS) are considered advanced usage and PHP only
+  has limited support for this.
+  In particular, enabling [secure TLS](#secure-tls-connections) may not be
+  supported.
+
+> Note that the HTTP CONNECT protocol does not support the notion of UDS paths.
+  The above works reasonably well because UDS is only used for the connection between
+  client and proxy server and the path will not actually passed over the protocol.
+  This implies that this does not support connecting to UDS destination paths.
+
+## Install
+
+The recommended way to install this library is [through Composer](https://getcomposer.org).

+* If you want to learn more about how the
+  [`ConnectorInterface`](https://github.com/reactphp/socket#connectorinterface)
+  and its usual implementations look like, refer to the documentation of the underlying
+  [react/socket](https://github.com/reactphp/socket) component.
+* If you want to learn more about processing streams of data, refer to the

+  [react/stream](https://github.com/reactphp/stream) component.
+* As an alternative to an HTTP CONNECT proxy, you may also want to look into
+  using a SOCKS (SOCKS4/SOCKS5) proxy instead.
+  You may want to use [clue/socks-react](https://github.com/clue/php-socks-react)
+  which also provides an implementation of the same
+  [`ConnectorInterface`](https://github.com/reactphp/socket#connectorinterface)
+  so that supporting either proxy protocol should be fairly trivial.
+* If you're dealing with public proxies, you'll likely have to work with mixed
+  quality and unreliable proxies. You may want to look into using
+  [clue/connection-manager-extra](https://github.com/clue/php-connection-manager-extra)
+  which allows retrying unreliable ones, implying connection timeouts,
+  concurrently working with multiple connectors and more.
+* If you're looking for an end-user HTTP CONNECT proxy server daemon, you may
+  want to use [LeProxy](https://leproxy.org/).

+ * This is most frequently used to issue HTTPS requests to your destination.

+ * Note that HTTP CONNECT proxies often restrict which ports one may connect to.
+ * Many (public) proxy servers do in fact limit this to HTTPS (443) only.
+ *
+ * If you want to establish a TLS connection (such as HTTPS) between you and
+ * your destination, you may want to wrap this connector in a SecureConnector
+ * instance.
+ *
+ * Note that communication between the client and the proxy is usually via an
+ * unencrypted, plain TCP/IP HTTP connection. Note that this is the most common
+ * setup, because you can still establish a TLS connection between you and the
+ * destination host as above.
+ *
+ * If you want to connect to a (rather rare) HTTPS proxy, you may want use its
+ * HTTPS port (443) and use a SecureConnector instance to create a secure
+ * connection to the proxy.

+
+* BC break: Remove HTTP support and link to [clue/buzz-react](https://github.com/clue/php-buzz-react) instead.
+  ([#9](https://github.com/clue/php-socks-react/pull/9))
+  
+  HTTP operates on a different layer than this low-level SOCKS library.
+  Removing this reduces the footprint of this library.
+  
+  > Upgrading? Check the [README](https://github.com/clue/php-socks-react#http-requests) for details.

+## Quickstart example
+
+Once [installed](#install), you can use the following code to create a connection
+to google.com via a local SOCKS proxy server:
+
+```php
+$loop = React\EventLoop\Factory::create();
+$client = new Client('127.0.0.1:1080', new Connector($loop));
+
+$client->connect('tcp://www.google.com:80')->then(function (ConnectionInterface $stream) {
+    $stream->write("GET / HTTP/1.0\r\n\r\n");
+});
+
+$loop->run();
+```
+
+If you're not already running any other [SOCKS proxy server](#servers),
+you can use the following code to create a SOCKS
+proxy server listening for connections on `localhost:1080`:
+
+```php
+$loop = React\EventLoop\Factory::create();
+
+// listen on localhost:1080
+$socket = new Socket('127.0.0.1:1080', $loop);
+
+// start a new server listening for incoming connection on the given socket
+$server = new Server($loop, $socket);
+
+$loop->run();
+```
+
+See also the [examples](examples).
+
+## Usage
+
+### ConnectorInterface
+
+The `ConnectorInterface` is responsible for providing an interface for
+establishing streaming connections, such as a normal TCP/IP connection.
+
+In order to use this library, you should understand how this integrates with its
+ecosystem.
+This base interface is actually defined in React's
+[Socket component](https://github.com/reactphp/socket) and used
+throughout React's ecosystem.
+
+Most higher-level components (such as HTTP, database or other networking
+service clients) accept an instance implementing this interface to create their
+TCP/IP connection to the underlying networking service.
+This is usually done via dependency injection, so it's fairly simple to actually
+swap this implementation against this library in order to connect through a
+SOCKS proxy server.
+
+The interface only offers a single method:
+
+#### connect()
+
+The `connect(string $uri): PromiseInterface<ConnectionInterface, Exception>` method
+can be used to establish a streaming connection.
+It returns a [Promise](https://github.com/reactphp/promise) which either
+fulfills with a [ConnectionInterface](https://github.com/reactphp/socket#connectioninterface) or
+rejects with an `Exception`:
+
+```php
+$connector->connect('tcp://google.com:80')->then(
+    function (ConnectionInterface $stream) {
+        // connection successfully established
+    },
+    function (Exception $error) {
+        // failed to connect due to $error
+    }
+);
+```
+
+### Client
+
+The `Client` is responsible for communication with your SOCKS server instance.
+Its constructor simply accepts an SOCKS proxy URI and a connector used to
+connect to the SOCKS proxy server address.
+
+In its most simple form, you can simply pass React's
+[`Connector`](https://github.com/reactphp/socket#connector)
+like this:
+
+```php
+$connector = new React\Socket\Connector($loop);
+$client = new Client('127.0.0.1:1080', $connector);
+```
+
+You can omit the port if you're using the default SOCKS port 1080:
+
+```php
+$client = new Client('127.0.0.1', $connector);
+```
+
+If you need custom connector settings (DNS resolution, timeouts etc.), you can explicitly pass a
+custom instance of the [`ConnectorInterface`](https://github.com/reactphp/socket#connectorinterface):
+
+```php
+// use local DNS server
+$dnsResolverFactory = new DnsFactory();
+$resolver = $dnsResolverFactory->createCached('127.0.0.1', $loop);
+
+// outgoing connections to SOCKS server via interface 192.168.10.1
+// this is not to be confused with local DNS resolution (see further below)
+$connector = new DnsConnector(
+    new TcpConnector($loop, array('bindto' => '192.168.10.1:0')),
+    $resolver
+);
+
+$client = new Client('my-socks-server.local:1080', $connector);
+```
+
+This is the main class in this package.
+Because it implements the the [`ConnectorInterface`](#connectorinterface), it
+can simply be used in place of a normal connector.
+This makes it fairly simple to add SOCKS proxy support to pretty much any
+higher-level component:
+
+```diff
+- $client = new SomeClient($connector);
++ $proxy = new Client('127.0.0.1:1080', $connector);
++ $client = new SomeClient($proxy);
+```
+
+#### Plain TCP connections
+
+The `Client` implements the [`ConnectorInterface`](#connectorinterface) and
+hence provides a single public method, the [`connect()`](#connect) method.
+Let's open up a streaming TCP/IP connection and write some data:
+
+```php
+$client->connect('tcp://www.google.com:80')->then(function (ConnectonInterface $stream) {
+    echo 'connected to www.google.com:80';
+    $stream->write("GET / HTTP/1.0\r\n\r\n");
+    // ...
+});
+```
+
+You can either use the `Client` directly or you may want to wrap this connector
+in React's [`Connector`](https://github.com/reactphp/socket#connector):
+
+```php
+$connector = new React\Socket\Connector($loop, array(
+    'tcp' => $client,
+    'dns' => false
+));
+
+$connector->connect('tcp://www.google.com:80')->then(function (ConnectonInterface $stream) {
+    echo 'connected to www.google.com:80';
+    $stream->write("GET / HTTP/1.0\r\n\r\n");
+    // ...
+});
+
+```
+
+See also the [first example](examples).
+
+The `tcp://` scheme can also be omitted.
+Passing any other scheme will reject the promise.
+
+Pending connection attempts can be canceled by canceling its pending promise like so:
+
+```php
+$promise = $connector->connect($uri);
+
+$promise->cancel();
+```
+
+Calling `cancel()` on a pending promise will cancel the underlying TCP/IP
+connection to the SOCKS server and/or the SOCKS protocol negotiation and reject
+the resulting promise.
+
+#### Secure TLS connections
+
+If you want to establish a secure TLS connection (such as HTTPS) between you and
+your destination, you may want to wrap this connector in React's
+[`Connector`](https://github.com/reactphp/socket#connector) or the low-level
+[`SecureConnector`](https://github.com/reactphp/socket#secureconnector):
+
+```php
+$connector = new React\Socket\Connector($loop, array(
+    'tcp' => $client,
+    'dns' => false
+));
+
+// now create an SSL encrypted connection (notice the $ssl instead of $tcp)
+$connector->connect('tls://www.google.com:443')->then(function (ConnectionInterface $stream) {
+    // proceed with just the plain text data
+    // everything is encrypted/decrypted automatically
+    echo 'connected to SSL encrypted www.google.com';
+    $stream->write("GET / HTTP/1.0\r\n\r\n");
+    // ...
+});
+```
+
+See also the [second example](examples).
+
+If you use the low-level `SecureConnector`, then the `tls://` scheme can also
+be omitted.
+Passing any other scheme will reject the promise.
+
+Pending connection attempts can be canceled by canceling its pending promise
+as usual.
+
+> Also note how secure TLS connections are in fact entirely handled outside of
+  this SOCKS client implementation.
+
+You can optionally pass additional
+[SSL context options](http://php.net/manual/en/context.ssl.php)
+to the constructor like this:
+
+```php
+$connector = new React\Socket\Connector($loop, array(
+    'tcp' => $client,
+    'tls' => array(
+        'verify_peer' => false,
+        'verify_peer_name' => false
+    ),
+    'dns' => false
+));
+```
+
+#### HTTP requests
+
+HTTP operates on a higher layer than this low-level SOCKS implementation.
+If you want to issue HTTP requests, you can add a dependency for
+[clue/buzz-react](https://github.com/clue/php-buzz-react).
+It can interact with this library by issuing all
+[http requests through a SOCKS server](https://github.com/clue/php-buzz-react#socks-proxy).
+This works for both plain HTTP and SSL encrypted HTTPS requests.
+
+#### Protocol version
+
+This library supports the SOCKS4, SOCKS4a and SOCKS5 protocol versions.
+
+While SOCKS4 already had (a somewhat limited) support for `SOCKS BIND` requests
+and SOCKS5 added generic UDP support (`SOCKS UDPASSOCIATE`), this library
+focuses on the most commonly used core feature of `SOCKS CONNECT`.
+In this mode, a SOCKS server acts as a generic proxy allowing higher level
+application protocols to work through it.

+</table>
+
+Note, this is __not__ a full SOCKS5 implementation due to missing GSSAPI
+authentication (but it's unlikely you're going to miss it anyway).
+
+By default, the `Client` communicates via SOCKS4a with the SOCKS server
+– unless you enable [authentication](#authentication), in which case it will
+default to SOCKS5.
+This is done because SOCKS4a incurs less overhead than SOCKS5 (see above) and
+is equivalent with SOCKS4 if you use [local DNS resolution](#dns-resolution).
+
+If want to explicitly set the protocol version, use the supported values URI
+schemes `socks4`, `socks4a` or `socks5` as part of the SOCKS URI:
+
+```php
+$client = new Client('socks5://127.0.0.1', $connector);
+```
+
+As seen above, both SOCKS5 and SOCKS4a support remote and local DNS resolution.
+If you've explicitly set this to SOCKS4, then you may want to check the following
+chapter about local DNS resolution or you may only connect to IPv4 addresses.
+
+#### DNS resolution
+
+By default, the `Client` does not perform any DNS resolution at all and simply
+forwards any hostname you're trying to connect to to the SOCKS server.
+The remote SOCKS server is thus responsible for looking up any hostnames via DNS
+(this default mode is thus called *remote DNS resolution*).
+As seen above, this mode is supported by the SOCKS5 and SOCKS4a protocols, but
+not the SOCKS4 protocol, as the protocol lacks a way to communicate hostnames.
+
+On the other hand, all SOCKS protocol versions support sending destination IP
+addresses to the SOCKS server.
+In this mode you either have to stick to using IPs only (which is ofen unfeasable)
+or perform any DNS lookups locally and only transmit the resolved destination IPs
+(this mode is thus called *local DNS resolution*).
+
+The default *remote DNS resolution* is useful if your local `Client` either can
+not resolve target hostnames because it has no direct access to the internet or
+if it should not resolve target hostnames because its outgoing DNS traffic might
+be intercepted (in particular when using the
+[Tor network](#using-the-tor-anonymity-network-to-tunnel-socks-connections)).
+
+As noted above, the `Client` defaults to using remote DNS resolution.
+However, wrapping the `Client` in React's
+[`Connector`](https://github.com/reactphp/socket#connector) actually
+performs local DNS resolution unless explicitly defined otherwise.
+Given that remote DNS resolution is assumed to be the preferred mode, all
+other examples explicitly disable DNS resoltion like this:
+
+```php
+$connector = new React\Socket\Connector($loop, array(
+    'tcp' => $client,
+    'dns' => false
+));
+```
+
+If you want to explicitly use *local DNS resolution* (such as when explicitly
+using SOCKS4), you can use the following code:
+
+```php
+// set up Connector which uses Google's public DNS (8.8.8.8)
+$connector = new React\Socket\Connector($loop, array(
+    'tcp' => $client,
+    'dns' => '8.8.8.8'
+));
+```
+
+See also the [fourth example](examples).
+
+Pending connection attempts can be canceled by canceling its pending promise
+as usual.
+
+> Also note how local DNS resolution is in fact entirely handled outside of this
+  SOCKS client implementation.
+
+If you've explicitly set the client to SOCKS4 and stick to the default
+*remote DNS resolution*, then you may only connect to IPv4 addresses because
+the protocol lacks a way to communicate hostnames.
+If you try to connect to a hostname despite, the resulting promise will be
+rejected right away.
+
+#### Authentication
+
+This library supports username/password authentication for SOCKS5 servers as
+defined in [RFC 1929](http://tools.ietf.org/html/rfc1929).
+
+On the client side, simply pass your username and password to use for
+authentication (see below).
+For each further connection the client will merely send a flag to the server
+indicating authentication information is available.
+Only if the server requests authentication during the initial handshake,
+the actual authentication credentials will be transmitted to the server.
+
+Note that the password is transmitted in cleartext to the SOCKS proxy server,
+so this methods should not be used on a network where you have to worry about eavesdropping.
+
+You can simply pass the authentication information as part of the SOCKS URI:
+
+```php
+$client = new Client('username:password@127.0.0.1', $connector);
+```
+
+Note that both the username and password must be percent-encoded if they contain
+special characters:
+
+```php
+$user = 'he:llo';
+$pass = 'p@ss';
+
+$client = new Client(
+    rawurlencode($user) . ':' . rawurlencode($pass) . '@127.0.0.1',
+    $connector
+);
+```
+
+> The authentication details will be transmitted in cleartext to the SOCKS proxy
+  server only if it requires username/password authentication.
+  If the authentication details are missing or not accepted by the remote SOCKS
+  proxy server, it is expected to reject each connection attempt with an
+  exception error code of `SOCKET_EACCES` (13).
+
+Authentication is only supported by protocol version 5 (SOCKS5),
+so passing authentication to the `Client` enforces communication with protocol
+version 5 and complains if you have explicitly set anything else:
+
+```php
+// throws InvalidArgumentException
+new Client('socks4://user:pass@127.0.0.1', $connector);
+```
+
+#### Proxy chaining
+
+The `Client` is responsible for creating connections to the SOCKS server which
+then connects to the target host.
+
+```
+Client -> SocksServer -> TargetHost
+```
+
+Sometimes it may be required to establish outgoing connections via another SOCKS
+server.
+For example, this can be useful if you want to conceal your origin address.
+
+```
+Client -> MiddlemanSocksServer -> TargetSocksServer -> TargetHost
+```
+
+The `Client` uses any instance of the `ConnectorInterface` to establish
+outgoing connections.
+In order to connect through another SOCKS server, you can simply use another
+SOCKS connector from another SOCKS client like this:
+
+```php
+// https via the proxy chain  "MiddlemanSocksServer -> TargetSocksServer -> TargetHost"
+// please note how the client uses TargetSocksServer (not MiddlemanSocksServer!),
+// which in turn then uses MiddlemanSocksServer.
+// this creates a TCP/IP connection to MiddlemanSocksServer, which then connects
+// to TargetSocksServer, which then connects to the TargetHost
+$middle = new Client('127.0.0.1:1080', new Connector($loop));
+$target = new Client('example.com:1080', $middle);
+
+$connector = new React\Socket\Connector($loop, array(
+    'tcp' => $target,
+    'dns' => false
+));
+
+$connector->connect('tls://www.google.com:443')->then(function ($stream) {
+    // …
+});
+```
+
+See also the [third example](examples).
+
+Pending connection attempts can be canceled by canceling its pending promise
+as usual.
+
+Proxy chaining can happen on the server side and/or the client side:
+
+* If you ask your client to chain through multiple proxies, then each proxy
+  server does not really know anything about chaining at all.
+  This means that this is a client-only property.
+
+* If you ask your server to chain through another proxy, then your client does
+  not really know anything about chaining at all.
+  This means that this is a server-only property and not part of this class.
+  For example, you can find this in the below [`Server`](#server-proxy-chaining)
+  class or somewhat similar when you're using the
+  [Tor network](#using-the-tor-anonymity-network-to-tunnel-socks-connections).
+
+#### Connection timeout
+
+By default, the `Client` does not implement any timeouts for establishing remote
+connections.
+Your underlying operating system may impose limits on pending and/or idle TCP/IP
+connections, anywhere in a range of a few minutes to several hours.
+
+Many use cases require more control over the timeout and likely values much
+smaller, usually in the range of a few seconds only.
+
+You can use React's [`Connector`](https://github.com/reactphp/socket#connector)
+or the low-level
+[`TimeoutConnector`](https://github.com/reactphp/socket#timeoutconnector)
+to decorate any given `ConnectorInterface` instance.
+It provides the same `connect()` method, but will automatically reject the
+underlying connection attempt if it takes too long:
+
+```php
+$connector = new Connector($loop, array(
+    'tcp' => $client,
+    'dns' => false,
+    'timeout' => 3.0
+));
+
+$connector->connect('tcp://google.com:80')->then(function ($stream) {
+    // connection succeeded within 3.0 seconds
+});
+```
+
+See also any of the [examples](examples).
+
+Pending connection attempts can be canceled by canceling its pending promise
+as usual.
+
+> Also note how connection timeout is in fact entirely handled outside of this
+  SOCKS client implementation.
+
+#### SOCKS over TLS
+
+All [SOCKS protocol versions](#protocol-version) support forwarding TCP/IP
+based connections and higher level protocols.
+This implies that you can also use [secure TLS connections](#secure-tls-connections)
+to transfer sensitive data across SOCKS proxy servers.
+This means that no eavesdropper nor the proxy server will be able to decrypt
+your data.
+
+However, the initial SOCKS communication between the client and the proxy is
+usually via an unencrypted, plain TCP/IP connection.
+This means that an eavesdropper may be able to see *where* you connect to and
+may also be able to see your [SOCKS authentication](#authentication) details
+in cleartext.
+
+As an alternative, you may establish a secure TLS connection to your SOCKS
+proxy before starting the initial SOCKS communication.
+This means that no eavesdroppper will be able to see the destination address
+you want to connect to or your [SOCKS authentication](#authentication) details.
+
+You can use the `sockss://` URI scheme or use an explicit
+[SOCKS protocol version](#protocol-version) like this:
+
+```php
+$client = new Client('sockss://127.0.0.1:1080', new Connector($loop));
+
+$client = new Client('socks5s://127.0.0.1:1080', new Connector($loop));
+```
+
+See also [example 32](examples).
+
+Simiarly, you can also combine this with [authentication](#authentication)
+like this:
+
+```php
+$client = new Client('sockss://user:pass@127.0.0.1:1080', new Connector($loop));
+```
+
+> Note that for most use cases, [secure TLS connections](#secure-tls-connections)
+  should be used instead. SOCKS over TLS is considered advanced usage and is
+  used very rarely in practice.
+  In particular, the SOCKS server has to accept secure TLS connections, see
+  also [Server SOCKS over TLS](#server-socks-over-tls) for more details.
+  Also, PHP does not support "double encryption" over a single connection.
+  This means that enabling [secure TLS connections](#secure-tls-connections)
+  over a communication channel that has been opened with SOCKS over TLS
+  may not be supported.
+
+> Note that the SOCKS protocol does not support the notion of TLS. The above
+  works reasonably well because TLS is only used for the connection between
+  client and proxy server and the SOCKS protocol data is otherwise identical.
+  This implies that this may also have only limited support for
+  [proxy chaining](#proxy-chaining) over multiple TLS paths.
+
+#### Unix domain sockets
+
+All [SOCKS protocol versions](#protocol-version) support forwarding TCP/IP
+based connections and higher level protocols.
+In some advanced cases, it may be useful to let your SOCKS server listen on a
+Unix domain socket (UDS) path instead of a IP:port combination.
+For example, this allows you to rely on file system permissions instead of
+having to rely on explicit [authentication](#authentication).
+
+You can use the `socks+unix://` URI scheme or use an explicit
+[SOCKS protocol version](#protocol-version) like this:
+
+```php
+$client = new Client('socks+unix:///tmp/proxy.sock', new Connector($loop));
+
+$client = new Client('socks5+unix:///tmp/proxy.sock', new Connector($loop));
+```
+
+Simiarly, you can also combine this with [authentication](#authentication)
+like this:
+
+```php
+$client = new Client('socks+unix://user:pass@/tmp/proxy.sock', new Connector($loop));
+```
+
+> Note that Unix domain sockets (UDS) are considered advanced usage and PHP only
+  has limited support for this.
+  In particular, enabling [secure TLS](#secure-tls-connections) may not be
+  supported.
+
+> Note that SOCKS protocol does not support the notion of UDS paths. The above
+  works reasonably well because UDS is only used for the connection between
+  client and proxy server and the path will not actually passed over the protocol.
+  This implies that this does also not support [proxy chaining](#proxy-chaining)
+  over multiple UDS paths.
+
+### Server
+
+The `Server` is responsible for accepting incoming communication from SOCKS clients
+and forwarding the requested connection to the target host.
+It also registers everything with the main [`EventLoop`](https://github.com/reactphp/event-loop#usage)
+and an underlying TCP/IP socket server like this:
+
+```php
+$loop = \React\EventLoop\Factory::create();
+
+// listen on localhost:$port
+$socket = new Socket($port, $loop);
+
+$server = new Server($loop, $socket);
+```
+
+#### Server connector
+
+The `Server` uses an instance of the [`ConnectorInterface`](#connectorinterface)
+to establish outgoing connections for each incoming connection request.
+
+If you need custom connector settings (DNS resolution, timeouts etc.), you can explicitly pass a
+custom instance of the [`ConnectorInterface`](https://github.com/reactphp/socket#connectorinterface):
+
+```php
+// use local DNS server
+$dnsResolverFactory = new DnsFactory();
+$resolver = $dnsResolverFactory->createCached('127.0.0.1', $loop);
+
+// outgoing connections to target host via interface 192.168.10.1
+$connector = new DnsConnector(
+    new TcpConnector($loop, array('bindto' => '192.168.10.1:0')),
+    $resolver
+);
+
+$server = new Server($loop, $socket, $connector);
+```
+
+If you want to forward the outgoing connection through another SOCKS proxy, you
+may also pass a [`Client`](#client) instance as a connector, see also
+[server proxy chaining](#server-proxy-chaining) for more details.
+
+Internally, the `Server` uses the normal [`connect()`](#connect) method, but
+it also passes the original client IP as the `?source={remote}` parameter.
+The `source` parameter contains the full remote URI, including the protocol
+and any authentication details, for example `socks5://user:pass@1.2.3.4:5678`.
+You can use this parameter for logging purposes or to restrict connection
+requests for certain clients by providing a custom implementation of the
+[`ConnectorInterface`](#connectorinterface).
+
+#### Server protocol version
+
+The `Server` supports all protocol versions (SOCKS4, SOCKS4a and SOCKS5) by default.
+
+If want to explicitly set the protocol version, use the supported values `4`, `4a` or `5`:
+
+```PHP
+$server->setProtocolVersion(5);
+```
+
+In order to reset the protocol version to its default (i.e. automatic detection),
+use `null` as protocol version.
+
+```PHP
+$server->setProtocolVersion(null);
+```
+
+#### Server authentication
+
+By default, the `Server` does not require any authentication from the clients.
+You can enable authentication support so that clients need to pass a valid
+username and password before forwarding any connections.
+
+Setting authentication on the `Server` enforces each further connected client
+to use protocol version 5 (SOCKS5).
+If a client tries to use any other protocol version, does not send along
+authentication details or if authentication details can not be verified,
+the connection will be rejected.
+
+Because your authentication mechanism might take some time to actually check
+the provided authentication credentials (like querying a remote database or webservice),
+the server side uses a [Promise](https://github.com/reactphp/promise) based interface.
+While this might seem complex at first, it actually provides a very simple way
+to handle simultanous connections in a non-blocking fashion and increases overall performance.
+
+```PHP
+$server->setAuth(function ($username, $password, $remote) {
+    // either return a boolean success value right away
+    // or use promises for delayed authentication
+
+    // $remote is a full URI à la socks5://user:pass@192.168.1.1:1234
+    // or socks5s://user:pass@192.168.1.1:1234 for SOCKS over TLS
+    // useful for logging or extracting parts, such as the remote IP
+    $ip = parse_url($remote, PHP_URL_HOST);
+
+    return ($username === 'root' && $ip === '127.0.0.1');
+});
+```
+
+Or if you only accept static authentication details, you can use the simple
+array-based authentication method as a shortcut:
+
+```PHP
+$server->setAuthArray(array(
+    'tom' => 'password',
+    'admin' => 'root'
+));
+```
+
+See also [example #12](examples).
+
+If you do not want to use authentication anymore:
+
+```PHP
+$server->unsetAuth();
+```
+
+#### Server proxy chaining
+
+The `Server` is responsible for creating connections to the target host.
+
+```
+Client -> SocksServer -> TargetHost
+```
+
+Sometimes it may be required to establish outgoing connections via another SOCKS
+server.
+For example, this can be useful if your target SOCKS server requires
+authentication, but your client does not support sending authentication
+information (e.g. like most webbrowser).
+
+```
+Client -> MiddlemanSocksServer -> TargetSocksServer -> TargetHost
+```
+
+The `Server` uses any instance of the `ConnectorInterface` to establish outgoing
+connections.
+In order to connect through another SOCKS server, you can simply use the
+[`Client`](#client) SOCKS connector from above.
+You can create a SOCKS `Client` instance like this: 
+
+```php
+// set next SOCKS server example.com:1080 as target
+$connector = new React\Socket\Connector($loop);
+$client = new Client('user:pass@example.com:1080', $connector);
+
+// listen on localhost:1080
+$socket = new Socket('127.0.0.1:1080', $loop);
+
+// start a new server which forwards all connections to the other SOCKS server
+$server = new Server($loop, $socket, $client);
+```
+
+See also [example #21](examples).
+
+Proxy chaining can happen on the server side and/or the client side:
+
+* If you ask your client to chain through multiple proxies, then each proxy
+  server does not really know anything about chaining at all.
+  This means that this is a client-only property and not part of this class.
+  For example, you can find this in the above [`Client`](#proxy-chaining) class.
+
+* If you ask your server to chain through another proxy, then your client does
+  not really know anything about chaining at all.
+  This means that this is a server-only property and can be implemented as above.
+
+#### Server SOCKS over TLS
+
+All [SOCKS protocol versions](#server-protocol-version) support forwarding TCP/IP
+based connections and higher level protocols.
+This implies that you can also use [secure TLS connections](#secure-tls-connections)
+to transfer sensitive data across SOCKS proxy servers.
+This means that no eavesdropper nor the proxy server will be able to decrypt
+your data.
+
+However, the initial SOCKS communication between the client and the proxy is
+usually via an unencrypted, plain TCP/IP connection.
+This means that an eavesdropper may be able to see *where* the client connects
+to and may also be able to see the [SOCKS authentication](#authentication)
+details in cleartext.
+
+As an alternative, you may listen for SOCKS over TLS connections so
+that the client has to establish a secure TLS connection to your SOCKS
+proxy before starting the initial SOCKS communication.
+This means that no eavesdroppper will be able to see the destination address
+the client wants to connect to or their [SOCKS authentication](#authentication)
+details.
+
+You can simply start your listening socket on the `tls://` URI scheme like this:
+
+```php
+$loop = \React\EventLoop\Factory::create();
+
+// listen on tls://127.0.0.1:1080 with the given server certificate
+$socket = new React\Socket\Server('tls://127.0.0.1:1080', $loop, array(
+    'tls' => array(
+        'local_cert' => __DIR__ . '/localhost.pem',
+    )
+));
+$server = new Server($loop, $socket);
+```
+
+See also [example 31](examples).
+
+> Note that for most use cases, [secure TLS connections](#secure-tls-connections)
+  should be used instead. SOCKS over TLS is considered advanced usage and is
+  used very rarely in practice.
+
+> Note that the SOCKS protocol does not support the notion of TLS. The above
+  works reasonably well because TLS is only used for the connection between
+  client and proxy server and the SOCKS protocol data is otherwise identical.
+  This implies that this does also not support [proxy chaining](#server-proxy-chaining)
+  over multiple TLS paths.
+
+#### Server Unix domain sockets
+
+All [SOCKS protocol versions](#server-protocol-version) support forwarding TCP/IP
+based connections and higher level protocols.
+In some advanced cases, it may be useful to let your SOCKS server listen on a
+Unix domain socket (UDS) path instead of a IP:port combination.

+
+You can simply start your listening socket on the `unix://` URI scheme like this:
+
+```php
+$loop = \React\EventLoop\Factory::create();
+
+// listen on /tmp/proxy.sock
+$socket = new React\Socket\Server('unix:///tmp/proxy.sock', $loop);
+$server = new Server($loop, $socket);
+```
+
+> Note that Unix domain sockets (UDS) are considered advanced usage and that
+  the SOCKS protocol does not support the notion of UDS paths. The above
+  works reasonably well because UDS is only used for the connection between
+  client and proxy server and the path will not actually passed over the protocol.
+  This implies that this does also not support [proxy chaining](#server-proxy-chaining)
+  over multiple UDS paths.
+
+## Servers
+
+### Using a PHP SOCKS server
+
+* If you're looking for an end-user SOCKS server daemon, you may want to use
+  [LeProxy](https://leproxy.org/) or [clue/psocksd](https://github.com/clue/psocksd).
+* If you're looking for a SOCKS server implementation, consider using
+  the above [`Server`](#server) class.
+
+### Using SSH as a SOCKS server
+
+If you already have an SSH server set up, you can easily use it as a SOCKS
+tunnel end point. On your client, simply start your SSH client and use
+the `-D <port>` option to start a local SOCKS server (quoting the man page:
+a `local "dynamic" application-level port forwarding`).
+
+You can start a local SOCKS server by creating a loopback connection to your
+local system if you already run an SSH daemon:
+
+```bash
+$ ssh -D 1080 localhost
+```
+
+Alternatively, you can start a local SOCKS server tunneling through a given
+remote host that runs an SSH daemon:
+
+```bash
+$ ssh -D 1080 example.com
+```
+
+Now you can simply use this SSH SOCKS server like this:
+
+```PHP
+$client = new Client('127.0.0.1:1080', $connector);
+```
+
+Note that the above will allow all users on the local system to connect over
+your SOCKS server without authentication which may or may not be what you need.
+As an alternative, recent OpenSSH client versions also support
+[Unix domain sockets](#unix-domain-sockets) (UDS) paths so that you can rely
+on Unix file system permissions instead:
+
+```bash
+$ ssh -D/tmp/proxy.sock example.com
+```
+
+Now you can simply use this SSH SOCKS server like this:
+
+```PHP
+$client = new Client('socks+unix:///tmp/proxy.sock', $connector);
+```
+
+### Using the Tor (anonymity network) to tunnel SOCKS connections
+
+The [Tor anonymity network](http://www.torproject.org) client software is designed
+to encrypt your traffic and route it over a network of several nodes to conceal its origin.
+It presents a SOCKS4 and SOCKS5 interface on TCP port 9050 by default
+which allows you to tunnel any traffic through the anonymity network.
+In most scenarios you probably don't want your client to resolve the target hostnames,
+because you would leak DNS information to anybody observing your local traffic.
+Also, Tor provides hidden services through an `.onion` pseudo top-level domain
+which have to be resolved by Tor.
+
+```PHP
+$client = new Client('127.0.0.1:9050', $connector);
+```

+  You may want to use [clue/http-proxy-react](https://github.com/clue/php-http-proxy-react)
+  which also provides an implementation of the
+  [`ConnectorInterface`](#connectorinterface) so that supporting either proxy
+  protocol should be fairly trivial.
+* If you're dealing with public proxies, you'll likely have to work with mixed
+  quality and unreliable proxies. You may want to look into using
+  [clue/connection-manager-extra](https://github.com/clue/php-connection-manager-extra)
+  which allows retrying unreliable ones, implying connection timeouts,
+  concurrently working with multiple connectors and more.
+* If you're looking for an end-user SOCKS server daemon, you may want to use
+  [LeProxy](https://leproxy.org/) or [clue/psocksd](https://github.com/clue/psocksd).

+## Synopsis
+
+```php
+use GetOptionKit\OptionCollection;
+use GetOptionKit\OptionParser;
+use GetOptionKit\OptionPrinter\ConsoleOptionPrinter;
+
+$specs = new OptionCollection;
+$specs->add('f|foo:', 'option requires a value.' )
+    ->isa('String');
+
+$specs->add('b|bar+', 'option with multiple value.' )
+    ->isa('Number');
+
+$specs->add('ip+', 'Ip constraint' )
+    ->isa('Ip');
+
+$specs->add('email+', 'Email address constraint' )
+    ->isa('Email');
+
+$specs->add('z|zoo?', 'option with optional value.' )
+    ->isa('Boolean');
+
+$specs->add('file:', 'option value should be a file.' )
+    ->isa('File');
+
+$specs->add('v|verbose', 'verbose message.' );
+$specs->add('d|debug', 'debug message.' );
+$specs->add('long', 'long option name only.' );
+$specs->add('s', 'short option name only.' );
+
+$printer = new ConsoleOptionPrinter();
+echo $printer->render($specs);
+
+$parser = new OptionParser($specs);
+
+echo "Enabled options: \n";
+try {
+    $result = $parser->parse( $argv );
+    foreach ($result->keys as $key => $spec) {
+        print_r($spec);
+    }
+
+    $opt = $result->keys['foo']; // return the option object.
+    $str = $result->keys['foo']->value; // return the option value
+    
+    print_r($opt);
+    var_dump($str);
+    
+} catch( Exception $e ) {
+    echo $e->getMessage();
+}
+```
+
+
+## Documentation
+
+See <https://github.com/c9s/GetOptionKit/wiki> for more details.
+
+### Option Value Type
+
+The option value type help you validate the input,
+the following list is the current supported types:
+
+- `string`
+- `number`
+- `boolean`
+- `file`
+- `date`
+- `url`
+- `email`
+- `ip`
+- `ipv4`
+- `ipv6`
+- `regex`
+
+And here is the related sample code:
+
+```php
+$opt->add( 'f|foo:' , 'with string type value' )
+    ->isa('string');
+
+$opt->add( 'b|bar+' , 'with number type value' )
+    ->isa('number');
+
+$opt->add( 'z|zoo?' , 'with boolean type value' )
+    ->isa('boolean');
+
+$opt->add( 'file:' , 'with file type value' )
+    ->isa('file');
+
+$opt->add( 'date:' , 'with date type value' )
+    ->isa('date');
+
+$opt->add( 'url:' , 'with url type value' )
+    ->isa('url');
+
+$opt->add( 'email:' , 'with email type value' )
+    ->isa('email');
+
+$opt->add( 'ip:' , 'with ip(v4/v6) type value' )
+    ->isa('ip');
+
+$opt->add( 'ipv4:' , 'with ipv4 type value' )
+    ->isa('ipv4');
+
+$opt->add( 'ipv6:' , 'with ipv6 type value' )
+    ->isa('ipv6');
+
+$specs->add('r|regex:', 'with custom regex type value')
+      ->isa('Regex', '/^([a-z]+)$/');
+```
+
+> Please note that currently only `string`, `number`, `boolean` types can be validated.
+
+### ContinuousOptionParser
+
+```php
+$specs = new OptionCollection;
+$spec_verbose = $specs->add('v|verbose');
+$spec_color = $specs->add('c|color');
+$spec_debug = $specs->add('d|debug');
+$spec_verbose->description = 'verbose flag';
+
+// ContinuousOptionParser
+$parser = new ContinuousOptionParser( $specs );
+$result = $parser->parse(explode(' ','program -v -d test -a -b -c subcommand -e -f -g subcommand2'));
+$result2 = $parser->continueParse();
+```
+
+### OptionPrinter
+
+GetOptionKit\OptionPrinter can print options for you:
+
+    * Available options:
+                  -f, --foo   option requires a value.
+                  -b, --bar   option with multiple value.
+                  -z, --zoo   option with optional value.
+              -v, --verbose   verbose message.
+                -d, --debug   debug message.
+                     --long   long option name only.
+                         -s   short option name only.
+
+
+## Command-line app with subcommands
+
+For application with subcommands is designed by following form:
+
+
+    [app name] [app opts] 
+                 [subcommand1] [subcommand-opts]
+                 [subcommand2] [subcommand-opts]
+                 [subcommand3] [subcommand-opts]
+                 [arguments]
+
+You can check the `tests/GetOptionKit/ContinuousOptionParserTest.php` unit test file:
+
+```php
+// subcommand stack
+$subcommands = array('subcommand1','subcommand2','subcommand3');
+
+// different command has its own options
+$subcommandSpecs = array(
+    'subcommand1' => $cmdspecs,
+    'subcommand2' => $cmdspecs,
+    'subcommand3' => $cmdspecs,
+);
+
+// for saved options
+$subcommandOptions = array();
+
+// command arguments
+$arguments = array();
+
+$argv = explode(' ','program -v -d -c subcommand1 -a -b -c subcommand2 -c subcommand3 arg1 arg2 arg3');
+
+// parse application options first
+$parser = new ContinuousOptionParser( $appspecs );
+$app_options = $parser->parse( $argv );
+while (! $parser->isEnd()) {
+    if (@$subcommands[0] && $parser->getCurrentArgument() == $subcommands[0]) {
+        $parser->advance();
+        $subcommand = array_shift( $subcommands );
+        $parser->setSpecs( $subcommandSpecs[$subcommand] );
+        $subcommandOptions[ $subcommand ] = $parser->continueParse();
+    } else {
+        $arguments[] = $parser->advance();
+    }
+}
+```
+
+## Todo
+
+* Option Spec group.
+* option valid value checking.
+* custom command mapping.
+
+## Command Line Utility Design Concept
+
+* main program name should be easy to type, easy to remember.
+* subcommand should be easy to type, easy to remember. length should be shorter than 7 characters.
+* options should always have long descriptive name
+* a program should be easy to check usage.
+
+## General command interface
+
+To list usage of all subcommands or the program itself:
+
+	$ prog help
+
+To list the subcommand usage
+
+	$ prog help subcommand subcommand2 subcommand3
+

+# Événement
+
+Événement is a very simple event dispatching library for PHP.
+
+It has the same design goals as [Silex](http://silex-project.org) and
+[Pimple](http://pimple-project.org), to empower the user while staying concise
+and simple.
+
+It is very strongly inspired by the EventEmitter API found in
+[node.js](http://nodejs.org).
+
+[![Build Status](https://secure.travis-ci.org/igorw/evenement.png?branch=master)](http://travis-ci.org/igorw/evenement)
+
+## Fetch
+
+The recommended way to install Événement is [through composer](http://getcomposer.org).
+
+Just create a composer.json file for your project:
+
+```JSON
+{
+    "require": {
+        "evenement/evenement": "^3.0 || ^2.0"
+    }
+}
+```
+
+**Note:** The `3.x` version of Événement requires PHP 7 and the `2.x` version requires PHP 5.4. If you are
+using PHP 5.3, please use the `1.x` version:
+
+```JSON
+{
+    "require": {
+        "evenement/evenement": "^1.0"
+    }
+}
+```
+
+And run these two commands to install it:
+
+    $ curl -s http://getcomposer.org/installer | php
+    $ php composer.phar install
+
+Now you can add the autoloader, and you will have access to the library:
+
+```php
+<?php
+require 'vendor/autoload.php';
+```
+
+## Usage
+
+### Creating an Emitter
+
+```php
+<?php
+$emitter = new Evenement\EventEmitter();
+```
+
+### Adding Listeners
+
+```php
+<?php
+$emitter->on('user.created', function (User $user) use ($logger) {
+    $logger->log(sprintf("User '%s' was created.", $user->getLogin()));
+});
+```
+
+### Emitting Events
+
+```php
+<?php
+$emitter->emit('user.created', [$user]);
+```
+

+# Introduction
+
+Événement is is French and means "event". The événement library aims to
+provide a simple way of subscribing to events and notifying those subscribers
+whenever an event occurs.
+
+The API that it exposes is almost a direct port of the EventEmitter API found
+in node.js. It also includes an "EventEmitter". There are some minor
+differences however.
+
+The EventEmitter is an implementation of the publish-subscribe pattern, which
+is a generalized version of the observer pattern. The observer pattern
+specifies an observable subject, which observers can register themselves to.
+Once something interesting happens, the subject notifies its observers.
+
+Pub/sub takes the same idea but encapsulates the observation logic inside a
+separate object which manages all of its subscribers or listeners. Subscribers
+are bound to an event name, and will only receive notifications of the events
+they subscribed to.
+
+**TLDR: What does evenement do, in short? It provides a mapping from event
+names to a list of listener functions and triggers each listener for a given
+event when it is emitted.**
+
+Why do we do this, you ask? To achieve decoupling.
+
+It allows you to design a system where the core will emit events, and modules
+are able to subscribe to these events. And respond to them.

+# API
+
+The API that événement exposes is defined by the
+`Evenement\EventEmitterInterface`. The interface is useful if you want to
+define an interface that extends the emitter and implicitly defines certain
+events to be emitted, or if you want to type hint an `EventEmitter` to be
+passed to a method without coupling to the specific implementation.
+
+## on($event, callable $listener)
+
+Allows you to subscribe to an event.
+
+Example:
+
+```php
+$emitter->on('user.created', function (User $user) use ($logger) {
+    $logger->log(sprintf("User '%s' was created.", $user->getLogin()));
+});
+```
+
+Since the listener can be any callable, you could also use an instance method
+instead of the anonymous function:
+
+```php
+$loggerSubscriber = new LoggerSubscriber($logger);
+$emitter->on('user.created', array($loggerSubscriber, 'onUserCreated'));
+```
+
+This has the benefit that listener does not even need to know that the emitter
+exists.
+
+You can also accept more than one parameter for the listener:
+
+```php
+$emitter->on('numbers_added', function ($result, $a, $b) {});
+```
+
+## once($event, callable $listener)
+
+Convenience method that adds a listener which is guaranteed to only be called
+once.
+
+Example:
+
+```php
+$conn->once('connected', function () use ($conn, $data) {
+    $conn->send($data);
+});
+```
+
+## emit($event, array $arguments = [])
+
+Emit an event, which will call all listeners.
+
+Example:
+
+```php
+$conn->emit('data', [$data]);
+```
+
+The second argument to emit is an array of listener arguments. This is how you
+specify more args:
+
+```php
+$result = $a + $b;
+$emitter->emit('numbers_added', [$result, $a, $b]);
+```
+
+## listeners($event)
+
+Allows you to inspect the listeners attached to an event. Particularly useful
+to check if there are any listeners at all.
+
+Example:
+
+```php
+$e = new \RuntimeException('Everything is broken!');
+if (0 === count($emitter->listeners('error'))) {
+    throw $e;
+}
+```
+
+## removeListener($event, callable $listener)
+
+Remove a specific listener for a specific event.
+
+## removeAllListeners($event = null)
+
+Remove all listeners for a specific event or all listeners all together. This
+is useful for long-running processes, where you want to remove listeners in
+order to allow them to get garbage collected.

+# Example: Plugin system
+
+In this example I will show you how to create a generic plugin system with
+événement where plugins can alter the behaviour of the app. The app is a blog.
+Boring, I know. By using the EventEmitter it will be easy to extend this blog
+with additional functionality without modifying the core system.
+
+The blog is quite basic. Users are able to create blog posts when they log in.
+The users are stored in a static config file, so there is no sign up process.
+Once logged in they get a "new post" link which gives them a form where they
+can create a new blog post with plain HTML. That will store the post in a
+document database. The index lists all blog post titles by date descending.
+Clicking on the post title will take you to the full post.
+
+## Plugin structure
+
+The goal of the plugin system is to allow features to be added to the blog
+without modifying any core files of the blog.
+
+The plugins are managed through a config file, `plugins.json`. This JSON file
+contains a JSON-encoded list of class-names for plugin classes. This allows
+you to enable and disable plugins in a central location. The initial
+`plugins.json` is just an empty array:
+```json
+[]
+```
+
+A plugin class must implement the `PluginInterface`:
+```php
+interface PluginInterface
+{
+    function attachEvents(EventEmitterInterface $emitter);
+}
+```
+
+The `attachEvents` method allows the plugin to attach any events to the
+emitter. For example:
+```php
+class FooPlugin implements PluginInterface
+{
+    public function attachEvents(EventEmitterInterface $emitter)
+    {
+        $emitter->on('foo', function () {
+            echo 'bar!';
+        });
+    }
+}
+```
+
+The blog system creates an emitter instance and loads the plugins:
+```php
+$emitter = new EventEmitter();
+
+$pluginClasses = json_decode(file_get_contents('plugins.json'), true);
+foreach ($pluginClasses as $pluginClass) {
+    $plugin = new $pluginClass();
+    $pluginClass->attachEvents($emitter);
+}
+```
+
+This is the base system. There are no plugins yet, and there are no events yet
+either. That's because I don't know which extension points will be needed. I
+will add them on demand.
+
+## Feature: Markdown
+
+Writing blog posts in HTML sucks! Wouldn't it be great if I could write them
+in a nice format such as markdown, and have that be converted to HTML for me?
+
+This feature will need two extension points. I need to be able to mark posts
+as markdown, and I need to be able to hook into the rendering of the post body
+and convert it from markdown to HTML. So the blog needs two new events:
+`post.create` and `post.render`.
+
+In the code that creates the post, I'll insert the `post.create` event:
+```php
+class PostEvent
+{
+    public $post;
+
+    public function __construct(array $post)
+    {
+        $this->post = $post;
+    }
+}
+
+$post = createPostFromRequest($_POST);
+
+$event = new PostEvent($post);
+$emitter->emit('post.create', [$event]);
+$post = $event->post;
+
+$db->save('post', $post);
+```
+
+This shows that you can wrap a value in an event object to make it mutable,
+allowing listeners to change it.
+
+The same thing for the `post.render` event:
+```php
+public function renderPostBody(array $post)
+{
+    $emitter = $this->emitter;
+
+    $event = new PostEvent($post);
+    $emitter->emit('post.render', [$event]);
+    $post = $event->post;
+
+    return $post['body'];
+}
+
+<h1><?= $post['title'] %></h1>
+<p><?= renderPostBody($post) %></p>
+```
+
+Ok, the events are in place. It's time to create the first plugin, woohoo! I
+will call this the `MarkdownPlugin`, so here's `plugins.json`:
+```json
+[
+    "MarkdownPlugin"
+]
+```
+
+The `MarkdownPlugin` class will be autoloaded, so I don't have to worry about
+including any files. I just have to worry about implementing the plugin class.
+The `markdown` function represents a markdown to HTML converter.
+```php
+class MarkdownPlugin implements PluginInterface
+{
+    public function attachEvents(EventEmitterInterface $emitter)
+    {
+        $emitter->on('post.create', function (PostEvent $event) {
+            $event->post['format'] = 'markdown';
+        });
+
+        $emitter->on('post.render', function (PostEvent $event) {
+            if (isset($event->post['format']) && 'markdown' === $event->post['format']) {
+                $event->post['body'] = markdown($event->post['body']);
+            }
+        });
+    }
+}
+```
+
+There you go, the blog now renders posts as markdown. But all of the previous
+posts before the addition of the markdown plugin are still rendered correctly
+as raw HTML.

+
+## 6.0.2 - 2015-07-04
+
+* Fixed a memory leak in the curl handlers in which references to callbacks
+  were not being removed by `curl_reset`.
+* Cookies are now extracted properly before redirects.
+* Cookies now allow more character ranges.
+* Decoded Content-Encoding responses are now modified to correctly reflect
+  their state if the encoding was automatically removed by a handler. This
+  means that the `Content-Encoding` header may be removed an the
+  `Content-Length` modified to reflect the message size after removing the
+  encoding.
+* Added a more explicit error message when trying to use `form_params` and
+  `multipart` in the same request.
+* Several fixes for HHVM support.
+* Functions are now conditionally required using an additional level of
+  indirection to help with global Composer installations.
+
+## 6.0.1 - 2015-05-27
+
+* Fixed a bug with serializing the `query` request option where the `&`
+  separator was missing.
+* Added a better error message for when `body` is provided as an array. Please
+  use `form_params` or `multipart` instead.
+* Various doc fixes.
+
+## 6.0.0 - 2015-05-26
+
+* See the UPGRADING.md document for more information.
+* Added `multipart` and `form_params` request options.
+* Added `synchronous` request option.
+* Added the `on_headers` request option.
+* Fixed `expect` handling.
+* No longer adding default middlewares in the client ctor. These need to be
+  present on the provided handler in order to work.
+* Requests are no longer initiated when sending async requests with the
+  CurlMultiHandler. This prevents unexpected recursion from requests completing
+  while ticking the cURL loop.
+* Removed the semantics of setting `default` to `true`. This is no longer
+  required now that the cURL loop is not ticked for async requests.
+* Added request and response logging middleware.
+* No longer allowing self signed certificates when using the StreamHandler.
+* Ensuring that `sink` is valid if saving to a file.
+* Request exceptions now include a "handler context" which provides handler
+  specific contextual information.
+* Added `GuzzleHttp\RequestOptions` to allow request options to be applied
+  using constants.
+* `$maxHandles` has been removed from CurlMultiHandler.
+* `MultipartPostBody` is now part of the `guzzlehttp/psr7` package.
+
+## 5.3.0 - 2015-05-19
+
+* Mock now supports `save_to`
+* Marked `AbstractRequestEvent::getTransaction()` as public.
+* Fixed a bug in which multiple headers using different casing would overwrite
+  previous headers in the associative array.
+* Added `Utils::getDefaultHandler()`
+* Marked `GuzzleHttp\Client::getDefaultUserAgent` as deprecated.
+* URL scheme is now always lowercased.
+
+## 6.0.0-beta.1
+
+* Requires PHP >= 5.5
+* Updated to use PSR-7
+  * Requires immutable messages, which basically means an event based system
+    owned by a request instance is no longer possible.
+  * Utilizing the [Guzzle PSR-7 package](https://github.com/guzzle/psr7).
+  * Removed the dependency on `guzzlehttp/streams`. These stream abstractions
+    are available in the `guzzlehttp/psr7` package under the `GuzzleHttp\Psr7`
+    namespace.
+* Added middleware and handler system
+  * Replaced the Guzzle event and subscriber system with a middleware system.
+  * No longer depends on RingPHP, but rather places the HTTP handlers directly
+    in Guzzle, operating on PSR-7 messages.
+  * Retry logic is now encapsulated in `GuzzleHttp\Middleware::retry`, which
+    means the `guzzlehttp/retry-subscriber` is now obsolete.
+  * Mocking responses is now handled using `GuzzleHttp\Handler\MockHandler`.
+* Asynchronous responses
+  * No longer supports the `future` request option to send an async request.
+    Instead, use one of the `*Async` methods of a client (e.g., `requestAsync`,
+    `getAsync`, etc.).
+  * Utilizing `GuzzleHttp\Promise` instead of React's promise library to avoid
+    recursion required by chaining and forwarding react promises. See
+    https://github.com/guzzle/promises
+  * Added `requestAsync` and `sendAsync` to send request asynchronously.
+  * Added magic methods for `getAsync()`, `postAsync()`, etc. to send requests
+    asynchronously.
+* Request options
+  * POST and form updates
+    * Added the `form_fields` and `form_files` request options.
+    * Removed the `GuzzleHttp\Post` namespace.
+    * The `body` request option no longer accepts an array for POST requests.
+  * The `exceptions` request option has been deprecated in favor of the
+    `http_errors` request options.
+  * The `save_to` request option has been deprecated in favor of `sink` request
+    option.
+* Clients no longer accept an array of URI template string and variables for
+  URI variables. You will need to expand URI templates before passing them
+  into a client constructor or request method.
+* Client methods `get()`, `post()`, `put()`, `patch()`, `options()`, etc. are
+  now magic methods that will send synchronous requests.
+* Replaced `Utils.php` with plain functions in `functions.php`.
+* Removed `GuzzleHttp\Collection`.
+* Removed `GuzzleHttp\BatchResults`. Batched pool results are now returned as
+  an array.
+* Removed `GuzzleHttp\Query`. Query string handling is now handled using an
+  associative array passed into the `query` request option. The query string
+  is serialized using PHP's `http_build_query`. If you need more control, you
+  can pass the query string in as a string.
+* `GuzzleHttp\QueryParser` has been replaced with the
+  `GuzzleHttp\Psr7\parse_query`.
+
+## 5.2.0 - 2015-01-27
+
+* Added `AppliesHeadersInterface` to make applying headers to a request based
+  on the body more generic and not specific to `PostBodyInterface`.
+* Reduced the number of stack frames needed to send requests.
+* Nested futures are now resolved in the client rather than the RequestFsm
+* Finishing state transitions is now handled in the RequestFsm rather than the
+  RingBridge.
+* Added a guard in the Pool class to not use recursion for request retries.
+
+## 5.1.0 - 2014-12-19
+
+* Pool class no longer uses recursion when a request is intercepted.
+* The size of a Pool can now be dynamically adjusted using a callback.
+  See https://github.com/guzzle/guzzle/pull/943.
+* Setting a request option to `null` when creating a request with a client will
+  ensure that the option is not set. This allows you to overwrite default
+  request options on a per-request basis.
+  See https://github.com/guzzle/guzzle/pull/937.
+* Added the ability to limit which protocols are allowed for redirects by
+  specifying a `protocols` array in the `allow_redirects` request option.
+* Nested futures due to retries are now resolved when waiting for synchronous
+  responses. See https://github.com/guzzle/guzzle/pull/947.
+* `"0"` is now an allowed URI path. See
+  https://github.com/guzzle/guzzle/pull/935.
+* `Query` no longer typehints on the `$query` argument in the constructor,
+  allowing for strings and arrays.
+* Exceptions thrown in the `end` event are now correctly wrapped with Guzzle
+  specific exceptions if necessary.
+
+## 5.0.3 - 2014-11-03
+
+This change updates query strings so that they are treated as un-encoded values
+by default where the value represents an un-encoded value to send over the
+wire. A Query object then encodes the value before sending over the wire. This
+means that even value query string values (e.g., ":") are url encoded. This
+makes the Query class match PHP's http_build_query function. However, if you
+want to send requests over the wire using valid query string characters that do
+not need to be encoded, then you can provide a string to Url::setQuery() and
+pass true as the second argument to specify that the query string is a raw
+string that should not be parsed or encoded (unless a call to getQuery() is
+subsequently made, forcing the query-string to be converted into a Query
+object).
+
+## 5.0.2 - 2014-10-30
+
+* Added a trailing `\r\n` to multipart/form-data payloads. See
+  https://github.com/guzzle/guzzle/pull/871
+* Added a `GuzzleHttp\Pool::send()` convenience method to match the docs.
+* Status codes are now returned as integers. See
+  https://github.com/guzzle/guzzle/issues/881
+* No longer overwriting an existing `application/x-www-form-urlencoded` header
+  when sending POST requests, allowing for customized headers. See
+  https://github.com/guzzle/guzzle/issues/877
+* Improved path URL serialization.
+
+  * No longer double percent-encoding characters in the path or query string if
+    they are already encoded.
+  * Now properly encoding the supplied path to a URL object, instead of only
+    encoding ' ' and '?'.
+  * Note: This has been changed in 5.0.3 to now encode query string values by
+    default unless the `rawString` argument is provided when setting the query
+    string on a URL: Now allowing many more characters to be present in the
+    query string without being percent encoded. See http://tools.ietf.org/html/rfc3986#appendix-A
+
+## 5.0.1 - 2014-10-16
+
+Bugfix release.
+
+* Fixed an issue where connection errors still returned response object in
+  error and end events event though the response is unusable. This has been
+  corrected so that a response is not returned in the `getResponse` method of
+  these events if the response did not complete. https://github.com/guzzle/guzzle/issues/867
+* Fixed an issue where transfer statistics were not being populated in the
+  RingBridge. https://github.com/guzzle/guzzle/issues/866
+
+## 5.0.0 - 2014-10-12
+
+Adding support for non-blocking responses and some minor API cleanup.
+
+### New Features
+
+* Added support for non-blocking responses based on `guzzlehttp/guzzle-ring`.
+* Added a public API for creating a default HTTP adapter.
+* Updated the redirect plugin to be non-blocking so that redirects are sent
+  concurrently. Other plugins like this can now be updated to be non-blocking.
+* Added a "progress" event so that you can get upload and download progress
+  events.
+* Added `GuzzleHttp\Pool` which implements FutureInterface and transfers
+  requests concurrently using a capped pool size as efficiently as possible.
+* Added `hasListeners()` to EmitterInterface.
+* Removed `GuzzleHttp\ClientInterface::sendAll` and marked
+  `GuzzleHttp\Client::sendAll` as deprecated (it's still there, just not the
+  recommended way).
+
+### Breaking changes
+
+The breaking changes in this release are relatively minor. The biggest thing to
+look out for is that request and response objects no longer implement fluent
+interfaces.
+
+* Removed the fluent interfaces (i.e., `return $this`) from requests,
+  responses, `GuzzleHttp\Collection`, `GuzzleHttp\Url`,
+  `GuzzleHttp\Query`, `GuzzleHttp\Post\PostBody`, and
+  `GuzzleHttp\Cookie\SetCookie`. This blog post provides a good outline of
+  why I did this: http://ocramius.github.io/blog/fluent-interfaces-are-evil/.
+  This also makes the Guzzle message interfaces compatible with the current
+  PSR-7 message proposal.
+* Removed "functions.php", so that Guzzle is truly PSR-4 compliant. Except
+  for the HTTP request functions from function.php, these functions are now
+  implemented in `GuzzleHttp\Utils` using camelCase. `GuzzleHttp\json_decode`
+  moved to `GuzzleHttp\Utils::jsonDecode`. `GuzzleHttp\get_path` moved to
+  `GuzzleHttp\Utils::getPath`. `GuzzleHttp\set_path` moved to
+  `GuzzleHttp\Utils::setPath`. `GuzzleHttp\batch` should now be
+  `GuzzleHttp\Pool::batch`, which returns an `objectStorage`. Using functions.php
+  caused problems for many users: they aren't PSR-4 compliant, require an
+  explicit include, and needed an if-guard to ensure that the functions are not
+  declared multiple times.
+* Rewrote adapter layer.
+    * Removing all classes from `GuzzleHttp\Adapter`, these are now
+      implemented as callables that are stored in `GuzzleHttp\Ring\Client`.
+    * Removed the concept of "parallel adapters". Sending requests serially or
+      concurrently is now handled using a single adapter.
+    * Moved `GuzzleHttp\Adapter\Transaction` to `GuzzleHttp\Transaction`. The
+      Transaction object now exposes the request, response, and client as public
+      properties. The getters and setters have been removed.
+* Removed the "headers" event. This event was only useful for changing the
+  body a response once the headers of the response were known. You can implement
+  a similar behavior in a number of ways. One example might be to use a
+  FnStream that has access to the transaction being sent. For example, when the
+  first byte is written, you could check if the response headers match your
+  expectations, and if so, change the actual stream body that is being
+  written to.
+* Removed the `asArray` parameter from
+  `GuzzleHttp\Message\MessageInterface::getHeader`. If you want to get a header
+  value as an array, then use the newly added `getHeaderAsArray()` method of
+  `MessageInterface`. This change makes the Guzzle interfaces compatible with
+  the PSR-7 interfaces.
+* `GuzzleHttp\Message\MessageFactory` no longer allows subclasses to add
+  custom request options using double-dispatch (this was an implementation
+  detail). Instead, you should now provide an associative array to the
+  constructor which is a mapping of the request option name mapping to a
+  function that applies the option value to a request.
+* Removed the concept of "throwImmediately" from exceptions and error events.
+  This control mechanism was used to stop a transfer of concurrent requests
+  from completing. This can now be handled by throwing the exception or by
+  cancelling a pool of requests or each outstanding future request individually.
+* Updated to "GuzzleHttp\Streams" 3.0.
+    * `GuzzleHttp\Stream\StreamInterface::getContents()` no longer accepts a
+      `maxLen` parameter. This update makes the Guzzle streams project
+      compatible with the current PSR-7 proposal.
+    * `GuzzleHttp\Stream\Stream::__construct`,
+      `GuzzleHttp\Stream\Stream::factory`, and
+      `GuzzleHttp\Stream\Utils::create` no longer accept a size in the second
+      argument. They now accept an associative array of options, including the
+      "size" key and "metadata" key which can be used to provide custom metadata.
+
+## 4.2.2 - 2014-09-08
+
+* Fixed a memory leak in the CurlAdapter when reusing cURL handles.
+* No longer using `request_fulluri` in stream adapter proxies.
+* Relative redirects are now based on the last response, not the first response.
+
+## 4.2.1 - 2014-08-19
+
+* Ensuring that the StreamAdapter does not always add a Content-Type header
+* Adding automated github releases with a phar and zip
+
+## 4.2.0 - 2014-08-17
+
+* Now merging in default options using a case-insensitive comparison.
+  Closes https://github.com/guzzle/guzzle/issues/767
+* Added the ability to automatically decode `Content-Encoding` response bodies
+  using the `decode_content` request option. This is set to `true` by default
+  to decode the response body if it comes over the wire with a
+  `Content-Encoding`. Set this value to `false` to disable decoding the
+  response content, and pass a string to provide a request `Accept-Encoding`
+  header and turn on automatic response decoding. This feature now allows you
+  to pass an `Accept-Encoding` header in the headers of a request but still
+  disable automatic response decoding.
+  Closes https://github.com/guzzle/guzzle/issues/764
+* Added the ability to throw an exception immediately when transferring
+  requests in parallel. Closes https://github.com/guzzle/guzzle/issues/760
+* Updating guzzlehttp/streams dependency to ~2.1
+* No longer utilizing the now deprecated namespaced methods from the stream
+  package.
+
+## 4.1.8 - 2014-08-14
+
+* Fixed an issue in the CurlFactory that caused setting the `stream=false`
+  request option to throw an exception.
+  See: https://github.com/guzzle/guzzle/issues/769
+* TransactionIterator now calls rewind on the inner iterator.
+  See: https://github.com/guzzle/guzzle/pull/765
+* You can now set the `Content-Type` header to `multipart/form-data`
+  when creating POST requests to force multipart bodies.
+  See https://github.com/guzzle/guzzle/issues/768
+
+## 4.1.7 - 2014-08-07
+
+* Fixed an error in the HistoryPlugin that caused the same request and response
+  to be logged multiple times when an HTTP protocol error occurs.
+* Ensuring that cURL does not add a default Content-Type when no Content-Type
+  has been supplied by the user. This prevents the adapter layer from modifying
+  the request that is sent over the wire after any listeners may have already
+  put the request in a desired state (e.g., signed the request).
+* Throwing an exception when you attempt to send requests that have the
+  "stream" set to true in parallel using the MultiAdapter.
+* Only calling curl_multi_select when there are active cURL handles. This was
+  previously changed and caused performance problems on some systems due to PHP
+  always selecting until the maximum select timeout.

+  created on disk unless a request succeeds.
+
+## 4.1.3 - 2014-07-15
+
+* Various fixes to multipart/form-data POST uploads
+* Wrapping function.php in an if-statement to ensure Guzzle can be used

+## 3.7.0 - 2013-06-10
+
+* See UPGRADING.md for more information on how to upgrade.
+* Requests now support the ability to specify an array of $options when creating a request to more easily modify a
+  request. You can pass a 'request.options' configuration setting to a client to apply default request options to
+  every request created by a client (e.g. default query string variables, headers, curl options, etc.).
+* Added a static facade class that allows you to use Guzzle with static methods and mount the class to `\Guzzle`.
+  See `Guzzle\Http\StaticClient::mount`.
+* Added `command.request_options` to `Guzzle\Service\Command\AbstractCommand` to pass request options to requests
+      created by a command (e.g. custom headers, query string variables, timeout settings, etc.).
+* Stream size in `Guzzle\Stream\PhpStreamRequestFactory` will now be set if Content-Length is returned in the
+  headers of a response
+* Added `Guzzle\Common\Collection::setPath($path, $value)` to set a value into an array using a nested key
+  (e.g. `$collection->setPath('foo/baz/bar', 'test'); echo $collection['foo']['bar']['bar'];`)
+* ServiceBuilders now support storing and retrieving arbitrary data
+* CachePlugin can now purge all resources for a given URI
+* CachePlugin can automatically purge matching cached items when a non-idempotent request is sent to a resource

+* `Guzzle\Common\Exception\ExceptionCollection` now creates a more readable exception message
+* Fixing BC break: Added back the MonologLogAdapter implementation rather than extending from PsrLog so that older
+  Symfony users can still use the old version of Monolog.
+* Fixing BC break: Added the implementation back in for `Guzzle\Http\Message\AbstractMessage::getTokenizedHeader()`.
+  Now triggering an E_USER_DEPRECATED warning when used. Use `$message->getHeader()->parseParams()`.
+* Several performance improvements to `Guzzle\Common\Collection`
+* Added an `$options` argument to the end of the following methods of `Guzzle\Http\ClientInterface`:
+  createRequest, head, delete, put, patch, post, options, prepareRequest
+* Added an `$options` argument to the end of `Guzzle\Http\Message\Request\RequestFactoryInterface::createRequest()`
+* Added an `applyOptions()` method to `Guzzle\Http\Message\Request\RequestFactoryInterface`
+* Changed `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $body = null)` to
+  `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $options = array())`. You can still pass in a
+  resource, string, or EntityBody into the $options parameter to specify the download location of the response.
+* Changed `Guzzle\Common\Collection::__construct($data)` to no longer accepts a null value for `$data` but a
+  default `array()`
+* Added `Guzzle\Stream\StreamInterface::isRepeatable`
+* Removed `Guzzle\Http\ClientInterface::setDefaultHeaders(). Use
+  $client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`. or
+  $client->getConfig()->setPath('request.options/headers', array('header_name' => 'value'))`.
+* Removed `Guzzle\Http\ClientInterface::getDefaultHeaders(). Use $client->getConfig()->getPath('request.options/headers')`.

+* Removed `Guzzle\Http\Message\RequestInterface::isRedirect`
+* Made `Guzzle\Http\Client::expandTemplate` and `getUriTemplate` protected methods.
+* You can now enable E_USER_DEPRECATED warnings to see if you are using a deprecated method by setting
+  `Guzzle\Common\Version::$emitWarnings` to true.
+* Marked `Guzzle\Http\Message\Request::isResponseBodyRepeatable()` as deprecated. Use
+      `$request->getResponseBody()->isRepeatable()` instead.

+  `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
+* Marked `Guzzle\Http\Message\Request::setIsRedirect()` as deprecated. Use the HistoryPlugin instead.
+* Marked `Guzzle\Http\Message\Request::isRedirect()` as deprecated. Use the HistoryPlugin instead.
+* Marked `Guzzle\Cache\CacheAdapterFactory::factory()` as deprecated
+* Marked 'command.headers', 'command.response_body' and 'command.on_complete' as deprecated for AbstractCommand.
+  These will work through Guzzle 4.0
+* Marked 'request.params' for `Guzzle\Http\Client` as deprecated. Use [request.options][params].
+* Marked `Guzzle\Service\Client::enableMagicMethods()` as deprecated. Magic methods can no longer be disabled on a Guzzle\Service\Client.
+* Marked `Guzzle\Service\Client::getDefaultHeaders()` as deprecated. Use $client->getConfig()->getPath('request.options/headers')`.
+* Marked `Guzzle\Service\Client::setDefaultHeaders()` as deprecated. Use $client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`.
+* Marked `Guzzle\Parser\Url\UrlParser` as deprecated. Just use PHP's `parse_url()` and percent encode your UTF-8.
+* Marked `Guzzle\Common\Collection::inject()` as deprecated.
+* Marked `Guzzle\Plugin\CurlAuth\CurlAuthPlugin` as deprecated. Use `$client->getConfig()->setPath('request.options/auth', array('user', 'pass', 'Basic|Digest');`
+* CacheKeyProviderInterface and DefaultCacheKeyProvider are no longer used. All of this logic is handled in a
+  CacheStorageInterface. These two objects and interface will be removed in a future version.
+* Always setting X-cache headers on cached responses
+* Default cache TTLs are now handled by the CacheStorageInterface of a CachePlugin
+* `CacheStorageInterface::cache($key, Response $response, $ttl = null)` has changed to `cache(RequestInterface
+  $request, Response $response);`

+  CanCacheStrategyInterface $canCache = null)`
+* Added `RevalidationInterface::shouldRevalidate(RequestInterface $request, Response $response)`
+
+## 3.6.0 - 2013-05-29
+
+* ServiceDescription now implements ToArrayInterface
+* Added command.hidden_params to blacklist certain headers from being treated as additionalParameters
+* Guzzle can now correctly parse incomplete URLs
+* Mixed casing of headers are now forced to be a single consistent casing across all values for that header.
+* Messages internally use a HeaderCollection object to delegate handling case-insensitive header resolution
+* Removed the whole changedHeader() function system of messages because all header changes now go through addHeader().
+* Specific header implementations can be created for complex headers. When a message creates a header, it uses a
+  HeaderFactory which can map specific headers to specific header classes. There is now a Link header and
+  CacheControl header implementation.
+* Removed from interface: Guzzle\Http\ClientInterface::setUriTemplate
+* Removed from interface: Guzzle\Http\ClientInterface::setCurlMulti()
+* Removed Guzzle\Http\Message\Request::receivedRequestHeader() and implemented this functionality in
+  Guzzle\Http\Curl\RequestMediator
+* Removed the optional $asString parameter from MessageInterface::getHeader(). Just cast the header to a string.
+* Removed the optional $tryChunkedTransfer option from Guzzle\Http\Message\EntityEnclosingRequestInterface
+* Removed the $asObjects argument from Guzzle\Http\Message\MessageInterface::getHeaders()
+* Removed Guzzle\Parser\ParserRegister::get(). Use getParser()
+* Removed Guzzle\Parser\ParserRegister::set(). Use registerParser().
+* All response header helper functions return a string rather than mixing Header objects and strings inconsistently
+* Removed cURL blacklist support. This is no longer necessary now that Expect, Accept, etc. are managed by Guzzle
+  directly via interfaces
+* Removed the injecting of a request object onto a response object. The methods to get and set a request still exist
+  but are a no-op until removed.
+* Most classes that used to require a `Guzzle\Service\Command\CommandInterface` typehint now request a
+  `Guzzle\Service\Command\ArrayCommandInterface`.
+* Added `Guzzle\Http\Message\RequestInterface::startResponse()` to the RequestInterface to handle injecting a response
+  on a request while the request is still being transferred
+* The ability to case-insensitively search for header values
+* Guzzle\Http\Message\Header::hasExactHeader
+* Guzzle\Http\Message\Header::raw. Use getAll()
+* Deprecated cache control specific methods on Guzzle\Http\Message\AbstractMessage. Use the CacheControl header object
+  instead.
+* `Guzzle\Service\Command\CommandInterface` now extends from ToArrayInterface and ArrayAccess
+* Added the ability to cast Model objects to a string to view debug information.
+
+## 3.5.0 - 2013-05-13
+
+* Bug: Fixed a regression so that request responses are parsed only once per oncomplete event rather than multiple times
+* Bug: Better cleanup of one-time events across the board (when an event is meant to fire once, it will now remove
+  itself from the EventDispatcher)
+* Bug: `Guzzle\Log\MessageFormatter` now properly writes "total_time" and "connect_time" values
+* Bug: Cloning an EntityEnclosingRequest now clones the EntityBody too
+* Bug: Fixed an undefined index error when parsing nested JSON responses with a sentAs parameter that reference a
+  non-existent key
+* Bug: All __call() method arguments are now required (helps with mocking frameworks)
+* Deprecating Response::getRequest() and now using a shallow clone of a request object to remove a circular reference
+  to help with refcount based garbage collection of resources created by sending a request
+* Deprecating ZF1 cache and log adapters. These will be removed in the next major version.
+* Deprecating `Response::getPreviousResponse()` (method signature still exists, but it's deprecated). Use the
+  HistoryPlugin for a history.
+* Added a `responseBody` alias for the `response_body` location
+* Refactored internals to no longer rely on Response::getRequest()
+* HistoryPlugin can now be cast to a string
+* HistoryPlugin now logs transactions rather than requests and responses to more accurately keep track of the requests
+  and responses that are sent over the wire
+* Added `getEffectiveUrl()` and `getRedirectCount()` to Response objects
+
+## 3.4.3 - 2013-04-30
+

+* LogPlugin now writes to php://output when STDERR is undefined
+* Added the ability to set multiple POST files for the same key in a single call
+* application/x-www-form-urlencoded POSTs now use the utf-8 charset by default
+* Added the ability to queue CurlExceptions to the MockPlugin

+* Configuration loading now allows remote files
+
+## 3.4.1 - 2013-04-16
+
+* Large refactoring to how CurlMulti handles work. There is now a proxy that sits in front of a pool of CurlMulti
+  handles. This greatly simplifies the implementation, fixes a couple bugs, and provides a small performance boost.
+* Exceptions are now properly grouped when sending requests in parallel
+* Redirects are now properly aggregated when a multi transaction fails
+* Redirects now set the response on the original object even in the event of a failure
+* Bug fix: Model names are now properly set even when using $refs
+* Added support for PHP 5.5's CurlFile to prevent warnings with the deprecated @ syntax
+* Added support for oauth_callback in OAuth signatures
+* Added support for oauth_verifier in OAuth signatures
+* Added support to attempt to retrieve a command first literally, then ucfirst, the with inflection
+

+* Bug fix: Fixed "array to string" error when validating a union of types in a service description
+* Bug fix: Removed code that attempted to determine the size of a stream when data is written to the stream
+* Bug fix: Not including an `oauth_token` if the value is null in the OauthPlugin.
+* Bug fix: Now correctly aggregating successful requests and failed requests in CurlMulti when a redirect occurs.
+* The new default CURLOPT_TIMEOUT setting has been increased to 150 seconds so that Guzzle works on poor connections.
+* Added a feature to EntityEnclosingRequest::setBody() that will automatically set the Content-Type of the request if
+  the Content-Type can be determined based on the entity body or the path of the request.
+* Added the ability to overwrite configuration settings in a client when grabbing a throwaway client from a builder.
+* Added support for a PSR-3 LogAdapter.
+* Added a `command.after_prepare` event
+* Added `oauth_callback` parameter to the OauthPlugin
+* Added the ability to create a custom stream class when using a stream factory
+* Added a CachingEntityBody decorator
+* Added support for `additionalParameters` in service descriptions to define how custom parameters are serialized.
+* The bundled SSL certificate is now provided in the phar file and extracted when running Guzzle from a phar.
+* You can now send any EntityEnclosingRequest with POST fields or POST files and cURL will handle creating bodies
+* POST requests using a custom entity body are now treated exactly like PUT requests but with a custom cURL method. This
+  means that the redirect behavior of POST requests with custom bodies will not be the same as POST requests that use
+  POST fields or files (the latter is only used when emulating a form POST in the browser).
+* Lots of cleanup to CurlHandle::factory and RequestFactory::createRequest
+
+## 3.3.1 - 2013-03-10
+
+* Added the ability to create PHP streaming responses from HTTP requests
+* Bug fix: Running any filters when parsing response headers with service descriptions

+* Bug fix: Removed the adding of default empty arrays and false Booleans to responses in order to be consistent across
+  response location visitors.
+* Bug fix: Removed the possibility of creating configuration files with circular dependencies
+* RequestFactory::create() now uses the key of a POST file when setting the POST file name

+
+## 3.3.0 - 2013-03-03
+
+* A large number of performance optimizations have been made

+* Bug fix: `Guzzle\Http\Message\Response::json()` now allows scalar values to be returned
+* Bug fix: Fixed bug in `Guzzle\Http\Message\Response` where wrapping quotes were stripped from `getEtag()`
+* BC: Removed `Guzzle\Http\Utils` class
+* BC: Setting a service description on a client will no longer modify the client's command factories.
+* BC: Emitting IO events from a RequestMediator is now a parameter that must be set in a request's curl options using

+Guzzle, PHP HTTP client
+=======================
+
+[![Latest Version](https://img.shields.io/github/release/guzzle/guzzle.svg?style=flat-square)](https://github.com/guzzle/guzzle/releases)
+[![Build Status](https://img.shields.io/travis/guzzle/guzzle.svg?style=flat-square)](https://travis-ci.org/guzzle/guzzle)
+[![Total Downloads](https://img.shields.io/packagist/dt/guzzlehttp/guzzle.svg?style=flat-square)](https://packagist.org/packages/guzzlehttp/guzzle)
+
+Guzzle is a PHP HTTP client that makes it easy to send HTTP requests and
+trivial to integrate with web services.
+
+- Simple interface for building query strings, POST requests, streaming large
+  uploads, streaming large downloads, using HTTP cookies, uploading JSON data,
+  etc...
+- Can send both synchronous and asynchronous requests using the same interface.
+- Uses PSR-7 interfaces for requests, responses, and streams. This allows you
+  to utilize other PSR-7 compatible libraries with Guzzle.
+- Abstracts away the underlying HTTP transport, allowing you to write
+  environment and transport agnostic code; i.e., no hard dependency on cURL,
+  PHP streams, sockets, or non-blocking event loops.
+- Middleware system allows you to augment and compose client behavior.
+
+```php
+$client = new \GuzzleHttp\Client();
+$response = $client->request('GET', 'https://api.github.com/repos/guzzle/guzzle');
+
+echo $response->getStatusCode(); # 200
+echo $response->getHeaderLine('content-type'); # 'application/json; charset=utf8'
+echo $response->getBody(); # '{"id": 1420053, "name": "guzzle", ...}'
+
+# Send an asynchronous request.
+$request = new \GuzzleHttp\Psr7\Request('GET', 'http://httpbin.org');
+$promise = $client->sendAsync($request)->then(function ($response) {
+    echo 'I completed! ' . $response->getBody();
+});
+
+$promise->wait();
+```

+
+## Installing Guzzle
+
+The recommended way to install Guzzle is through
+[Composer](http://getcomposer.org).
+
+```bash
+# Install Composer
+curl -sS https://getcomposer.org/installer | php
+```
+
+Next, run the Composer command to install the latest stable version of Guzzle:
+
+```bash
+composer require guzzlehttp/guzzle
+```
+
+After installing, you need to require Composer's autoloader:
+
+```php
+require 'vendor/autoload.php';
+```
+
+You can then later update Guzzle using composer:

+Guzzle Upgrade Guide
+====================
+
+5.0 to 6.0
+----------
+
+Guzzle now uses [PSR-7](http://www.php-fig.org/psr/psr-7/) for HTTP messages.
+Due to the fact that these messages are immutable, this prompted a refactoring
+of Guzzle to use a middleware based system rather than an event system. Any
+HTTP message interaction (e.g., `GuzzleHttp\Message\Request`) need to be
+updated to work with the new immutable PSR-7 request and response objects. Any
+event listeners or subscribers need to be updated to become middleware
+functions that wrap handlers (or are injected into a
+`GuzzleHttp\HandlerStack`).
+
+- Removed `GuzzleHttp\BatchResults`
+- Removed `GuzzleHttp\Collection`
+- Removed `GuzzleHttp\HasDataTrait`
+- Removed `GuzzleHttp\ToArrayInterface`
+- The `guzzlehttp/streams` dependency has been removed. Stream functionality
+  is now present in the `GuzzleHttp\Psr7` namespace provided by the
+  `guzzlehttp/psr7` package.
+- Guzzle no longer uses ReactPHP promises and now uses the
+  `guzzlehttp/promises` library. We use a custom promise library for three
+  significant reasons:
+  1. React promises (at the time of writing this) are recursive. Promise
+     chaining and promise resolution will eventually blow the stack. Guzzle
+     promises are not recursive as they use a sort of trampolining technique.
+     Note: there has been movement in the React project to modify promises to
+     no longer utilize recursion.
+  2. Guzzle needs to have the ability to synchronously block on a promise to
+     wait for a result. Guzzle promises allows this functionality (and does
+     not require the use of recursion).
+  3. Because we need to be able to wait on a result, doing so using React
+     promises requires wrapping react promises with RingPHP futures. This
+     overhead is no longer needed, reducing stack sizes, reducing complexity,
+     and improving performance.
+- `GuzzleHttp\Mimetypes` has been moved to a function in
+  `GuzzleHttp\Psr7\mimetype_from_extension` and
+  `GuzzleHttp\Psr7\mimetype_from_filename`.
+- `GuzzleHttp\Query` and `GuzzleHttp\QueryParser` have been removed. Query
+  strings must now be passed into request objects as strings, or provided to
+  the `query` request option when creating requests with clients. The `query`
+  option uses PHP's `http_build_query` to convert an array to a string. If you
+  need a different serialization technique, you will need to pass the query
+  string in as a string. There are a couple helper functions that will make
+  working with query strings easier: `GuzzleHttp\Psr7\parse_query` and
+  `GuzzleHttp\Psr7\build_query`.
+- Guzzle no longer has a dependency on RingPHP. Due to the use of a middleware
+  system based on PSR-7, using RingPHP and it's middleware system as well adds
+  more complexity than the benefits it provides. All HTTP handlers that were
+  present in RingPHP have been modified to work directly with PSR-7 messages
+  and placed in the `GuzzleHttp\Handler` namespace. This significantly reduces
+  complexity in Guzzle, removes a dependency, and improves performance. RingPHP
+  will be maintained for Guzzle 5 support, but will no longer be a part of
+  Guzzle 6.
+- As Guzzle now uses a middleware based systems the event system and RingPHP
+  integration has been removed. Note: while the event system has been removed,
+  it is possible to add your own type of event system that is powered by the
+  middleware system.
+  - Removed the `Event` namespace.
+  - Removed the `Subscriber` namespace.
+  - Removed `Transaction` class
+  - Removed `RequestFsm`
+  - Removed `RingBridge`
+  - `GuzzleHttp\Subscriber\Cookie` is now provided by
+    `GuzzleHttp\Middleware::cookies`
+  - `GuzzleHttp\Subscriber\HttpError` is now provided by
+    `GuzzleHttp\Middleware::httpError`
+  - `GuzzleHttp\Subscriber\History` is now provided by
+    `GuzzleHttp\Middleware::history`
+  - `GuzzleHttp\Subscriber\Mock` is now provided by
+    `GuzzleHttp\Handler\MockHandler`
+  - `GuzzleHttp\Subscriber\Prepare` is now provided by
+    `GuzzleHttp\PrepareBodyMiddleware`
+  - `GuzzleHttp\Subscriber\Redirect` is now provided by
+    `GuzzleHttp\RedirectMiddleware`
+- Guzzle now uses `Psr\Http\Message\UriInterface` (implements in
+  `GuzzleHttp\Psr7\Uri`) for URI support. `GuzzleHttp\Url` is now gone.
+- Static functions in `GuzzleHttp\Utils` have been moved to namespaced
+  functions under the `GuzzleHttp` namespace. This requires either a Composer
+  based autoloader or you to include functions.php.
+- `GuzzleHttp\ClientInterface::getDefaultOption` has been renamed to
+  `GuzzleHttp\ClientInterface::getConfig`.
+- `GuzzleHttp\ClientInterface::setDefaultOption` has been removed.
+- The `json` and `xml` methods of response objects has been removed. With the
+  migration to strictly adhering to PSR-7 as the interface for Guzzle messages,
+  adding methods to message interfaces would actually require Guzzle messages
+  to extend from PSR-7 messages rather then work with them directly.
+
+## Migrating to middleware
+
+The change to PSR-7 unfortunately required significant refactoring to Guzzle
+due to the fact that PSR-7 messages are immutable. Guzzle 5 relied on an event
+system from plugins. The event system relied on mutability of HTTP messages and
+side effects in order to work. With immutable messages, you have to change your
+workflow to become more about either returning a value (e.g., functional
+middlewares) or setting a value on an object. Guzzle v6 has chosen the
+functional middleware approach.
+
+Instead of using the event system to listen for things like the `before` event,
+you now create a stack based middleware function that intercepts a request on
+the way in and the promise of the response on the way out. This is a much
+simpler and more predictable approach than the event system and works nicely
+with PSR-7 middleware. Due to the use of promises, the middleware system is
+also asynchronous.
+
+v5:
+
+```php
+use GuzzleHttp\Event\BeforeEvent;
+$client = new GuzzleHttp\Client();
+// Get the emitter and listen to the before event.
+$client->getEmitter()->on('before', function (BeforeEvent $e) {
+    // Guzzle v5 events relied on mutation
+    $e->getRequest()->setHeader('X-Foo', 'Bar');
+});
+```
+
+v6:
+
+In v6, you can modify the request before it is sent using the `mapRequest`
+middleware. The idiomatic way in v6 to modify the request/response lifecycle is
+to setup a handler middleware stack up front and inject the handler into a
+client.
+
+```php
+use GuzzleHttp\Middleware;
+// Create a handler stack that has all of the default middlewares attached
+$handler = GuzzleHttp\HandlerStack::create();
+// Push the handler onto the handler stack
+$handler->push(Middleware::mapRequest(function (RequestInterface $request) {
+    // Notice that we have to return a request object
+    return $request->withHeader('X-Foo', 'Bar');
+}));
+// Inject the handler into the client
+$client = new GuzzleHttp\Client(['handler' => $handler]);
+```
+
+## POST Requests
+
+This version added the [`form_params`](http://guzzle.readthedocs.org/en/latest/request-options.html#form_params)
+and `multipart` request options. `form_params` is an associative array of
+strings or array of strings and is used to serialize an
+`application/x-www-form-urlencoded` POST request. The
+[`multipart`](http://guzzle.readthedocs.org/en/latest/request-options.html#multipart)
+option is now used to send a multipart/form-data POST request.
+
+`GuzzleHttp\Post\PostFile` has been removed. Use the `multipart` option to add
+POST files to a multipart/form-data request.
+
+The `body` option no longer accepts an array to send POST requests. Please use
+`multipart` or `form_params` instead.
+
+The `base_url` option has been renamed to `base_uri`.
+
+4.x to 5.0
+----------
+
+## Rewritten Adapter Layer
+
+Guzzle now uses [RingPHP](http://ringphp.readthedocs.org/en/latest) to send
+HTTP requests. The `adapter` option in a `GuzzleHttp\Client` constructor
+is still supported, but it has now been renamed to `handler`. Instead of
+passing a `GuzzleHttp\Adapter\AdapterInterface`, you must now pass a PHP
+`callable` that follows the RingPHP specification.
+
+## Removed Fluent Interfaces
+
+[Fluent interfaces were removed](http://ocramius.github.io/blog/fluent-interfaces-are-evil)
+from the following classes:
+
+- `GuzzleHttp\Collection`
+- `GuzzleHttp\Url`
+- `GuzzleHttp\Query`
+- `GuzzleHttp\Post\PostBody`
+- `GuzzleHttp\Cookie\SetCookie`
+
+## Removed functions.php
+
+Removed "functions.php", so that Guzzle is truly PSR-4 compliant. The following
+functions can be used as replacements.
+
+- `GuzzleHttp\json_decode` -> `GuzzleHttp\Utils::jsonDecode`
+- `GuzzleHttp\get_path` -> `GuzzleHttp\Utils::getPath`
+- `GuzzleHttp\Utils::setPath` -> `GuzzleHttp\set_path`
+- `GuzzleHttp\Pool::batch` -> `GuzzleHttp\batch`. This function is, however,
+  deprecated in favor of using `GuzzleHttp\Pool::batch()`.
+
+The "procedural" global client has been removed with no replacement (e.g.,
+`GuzzleHttp\get()`, `GuzzleHttp\post()`, etc.). Use a `GuzzleHttp\Client`
+object as a replacement.
+
+## `throwImmediately` has been removed
+
+The concept of "throwImmediately" has been removed from exceptions and error
+events. This control mechanism was used to stop a transfer of concurrent
+requests from completing. This can now be handled by throwing the exception or
+by cancelling a pool of requests or each outstanding future request
+individually.
+
+## headers event has been removed
+
+Removed the "headers" event. This event was only useful for changing the
+body a response once the headers of the response were known. You can implement
+a similar behavior in a number of ways. One example might be to use a
+FnStream that has access to the transaction being sent. For example, when the
+first byte is written, you could check if the response headers match your
+expectations, and if so, change the actual stream body that is being
+written to.
+
+## Updates to HTTP Messages
+
+Removed the `asArray` parameter from
+`GuzzleHttp\Message\MessageInterface::getHeader`. If you want to get a header
+value as an array, then use the newly added `getHeaderAsArray()` method of
+`MessageInterface`. This change makes the Guzzle interfaces compatible with
+the PSR-7 interfaces.
+
+3.x to 4.0
+----------
+
+## Overarching changes:
+
+- Now requires PHP 5.4 or greater.
+- No longer requires cURL to send requests.
+- Guzzle no longer wraps every exception it throws. Only exceptions that are
+  recoverable are now wrapped by Guzzle.
+- Various namespaces have been removed or renamed.
+- No longer requiring the Symfony EventDispatcher. A custom event dispatcher
+  based on the Symfony EventDispatcher is
+  now utilized in `GuzzleHttp\Event\EmitterInterface` (resulting in significant
+  speed and functionality improvements).
+
+Changes per Guzzle 3.x namespace are described below.
+
+## Batch
+
+The `Guzzle\Batch` namespace has been removed. This is best left to
+third-parties to implement on top of Guzzle's core HTTP library.
+
+## Cache
+
+The `Guzzle\Cache` namespace has been removed. (Todo: No suitable replacement
+has been implemented yet, but hoping to utilize a PSR cache interface).
+
+## Common
+
+- Removed all of the wrapped exceptions. It's better to use the standard PHP
+  library for unrecoverable exceptions.
+- `FromConfigInterface` has been removed.
+- `Guzzle\Common\Version` has been removed. The VERSION constant can be found
+  at `GuzzleHttp\ClientInterface::VERSION`.
+
+### Collection
+
+- `getAll` has been removed. Use `toArray` to convert a collection to an array.
+- `inject` has been removed.
+- `keySearch` has been removed.
+- `getPath` no longer supports wildcard expressions. Use something better like
+  JMESPath for this.
+- `setPath` now supports appending to an existing array via the `[]` notation.
+
+### Events
+
+Guzzle no longer requires Symfony's EventDispatcher component. Guzzle now uses
+`GuzzleHttp\Event\Emitter`.
+
+- `Symfony\Component\EventDispatcher\EventDispatcherInterface` is replaced by
+  `GuzzleHttp\Event\EmitterInterface`.
+- `Symfony\Component\EventDispatcher\EventDispatcher` is replaced by
+  `GuzzleHttp\Event\Emitter`.
+- `Symfony\Component\EventDispatcher\Event` is replaced by
+  `GuzzleHttp\Event\Event`, and Guzzle now has an EventInterface in
+  `GuzzleHttp\Event\EventInterface`.
+- `AbstractHasDispatcher` has moved to a trait, `HasEmitterTrait`, and
+  `HasDispatcherInterface` has moved to `HasEmitterInterface`. Retrieving the
+  event emitter of a request, client, etc. now uses the `getEmitter` method
+  rather than the `getDispatcher` method.
+
+#### Emitter
+
+- Use the `once()` method to add a listener that automatically removes itself
+  the first time it is invoked.
+- Use the `listeners()` method to retrieve a list of event listeners rather than
+  the `getListeners()` method.
+- Use `emit()` instead of `dispatch()` to emit an event from an emitter.
+- Use `attach()` instead of `addSubscriber()` and `detach()` instead of
+  `removeSubscriber()`.
+
+```php
+$mock = new Mock();
+// 3.x
+$request->getEventDispatcher()->addSubscriber($mock);
+$request->getEventDispatcher()->removeSubscriber($mock);
+// 4.x
+$request->getEmitter()->attach($mock);
+$request->getEmitter()->detach($mock);
+```
+
+Use the `on()` method to add a listener rather than the `addListener()` method.
+
+```php
+// 3.x
+$request->getEventDispatcher()->addListener('foo', function (Event $event) { /* ... */ } );
+// 4.x
+$request->getEmitter()->on('foo', function (Event $event, $name) { /* ... */ } );
+```
+
+## Http
+
+### General changes
+
+- The cacert.pem certificate has been moved to `src/cacert.pem`.
+- Added the concept of adapters that are used to transfer requests over the
+  wire.
+- Simplified the event system.
+- Sending requests in parallel is still possible, but batching is no longer a
+  concept of the HTTP layer. Instead, you must use the `complete` and `error`
+  events to asynchronously manage parallel request transfers.
+- `Guzzle\Http\Url` has moved to `GuzzleHttp\Url`.
+- `Guzzle\Http\QueryString` has moved to `GuzzleHttp\Query`.
+- QueryAggregators have been rewritten so that they are simply callable
+  functions.
+- `GuzzleHttp\StaticClient` has been removed. Use the functions provided in
+  `functions.php` for an easy to use static client instance.
+- Exceptions in `GuzzleHttp\Exception` have been updated to all extend from
+  `GuzzleHttp\Exception\TransferException`.
+
+### Client
+
+Calling methods like `get()`, `post()`, `head()`, etc. no longer create and
+return a request, but rather creates a request, sends the request, and returns
+the response.
+
+```php
+// 3.0
+$request = $client->get('/');
+$response = $request->send();
+
+// 4.0
+$response = $client->get('/');
+
+// or, to mirror the previous behavior
+$request = $client->createRequest('GET', '/');
+$response = $client->send($request);
+```
+
+`GuzzleHttp\ClientInterface` has changed.
+
+- The `send` method no longer accepts more than one request. Use `sendAll` to
+  send multiple requests in parallel.
+- `setUserAgent()` has been removed. Use a default request option instead. You
+  could, for example, do something like:
+  `$client->setConfig('defaults/headers/User-Agent', 'Foo/Bar ' . $client::getDefaultUserAgent())`.
+- `setSslVerification()` has been removed. Use default request options instead,
+  like `$client->setConfig('defaults/verify', true)`.
+
+`GuzzleHttp\Client` has changed.
+
+- The constructor now accepts only an associative array. You can include a
+  `base_url` string or array to use a URI template as the base URL of a client.
+  You can also specify a `defaults` key that is an associative array of default
+  request options. You can pass an `adapter` to use a custom adapter,
+  `batch_adapter` to use a custom adapter for sending requests in parallel, or
+  a `message_factory` to change the factory used to create HTTP requests and
+  responses.
+- The client no longer emits a `client.create_request` event.
+- Creating requests with a client no longer automatically utilize a URI
+  template. You must pass an array into a creational method (e.g.,
+  `createRequest`, `get`, `put`, etc.) in order to expand a URI template.
+
+### Messages
+
+Messages no longer have references to their counterparts (i.e., a request no
+longer has a reference to it's response, and a response no loger has a
+reference to its request). This association is now managed through a
+`GuzzleHttp\Adapter\TransactionInterface` object. You can get references to
+these transaction objects using request events that are emitted over the
+lifecycle of a request.
+
+#### Requests with a body
+
+- `GuzzleHttp\Message\EntityEnclosingRequest` and
+  `GuzzleHttp\Message\EntityEnclosingRequestInterface` have been removed. The
+  separation between requests that contain a body and requests that do not
+  contain a body has been removed, and now `GuzzleHttp\Message\RequestInterface`
+  handles both use cases.
+- Any method that previously accepts a `GuzzleHttp\Response` object now accept a
+  `GuzzleHttp\Message\ResponseInterface`.
+- `GuzzleHttp\Message\RequestFactoryInterface` has been renamed to
+  `GuzzleHttp\Message\MessageFactoryInterface`. This interface is used to create
+  both requests and responses and is implemented in
+  `GuzzleHttp\Message\MessageFactory`.
+- POST field and file methods have been removed from the request object. You
+  must now use the methods made available to `GuzzleHttp\Post\PostBodyInterface`
+  to control the format of a POST body. Requests that are created using a
+  standard `GuzzleHttp\Message\MessageFactoryInterface` will automatically use
+  a `GuzzleHttp\Post\PostBody` body if the body was passed as an array or if
+  the method is POST and no body is provided.
+
+```php
+$request = $client->createRequest('POST', '/');
+$request->getBody()->setField('foo', 'bar');
+$request->getBody()->addFile(new PostFile('file_key', fopen('/path/to/content', 'r')));
+```
+
+#### Headers
+
+- `GuzzleHttp\Message\Header` has been removed. Header values are now simply
+  represented by an array of values or as a string. Header values are returned
+  as a string by default when retrieving a header value from a message. You can
+  pass an optional argument of `true` to retrieve a header value as an array
+  of strings instead of a single concatenated string.
+- `GuzzleHttp\PostFile` and `GuzzleHttp\PostFileInterface` have been moved to
+  `GuzzleHttp\Post`. This interface has been simplified and now allows the
+  addition of arbitrary headers.
+- Custom headers like `GuzzleHttp\Message\Header\Link` have been removed. Most
+  of the custom headers are now handled separately in specific
+  subscribers/plugins, and `GuzzleHttp\Message\HeaderValues::parseParams()` has
+  been updated to properly handle headers that contain parameters (like the
+  `Link` header).
+
+#### Responses
+
+- `GuzzleHttp\Message\Response::getInfo()` and
+  `GuzzleHttp\Message\Response::setInfo()` have been removed. Use the event
+  system to retrieve this type of information.
+- `GuzzleHttp\Message\Response::getRawHeaders()` has been removed.
+- `GuzzleHttp\Message\Response::getMessage()` has been removed.
+- `GuzzleHttp\Message\Response::calculateAge()` and other cache specific
+  methods have moved to the CacheSubscriber.
+- Header specific helper functions like `getContentMd5()` have been removed.
+  Just use `getHeader('Content-MD5')` instead.
+- `GuzzleHttp\Message\Response::setRequest()` and
+  `GuzzleHttp\Message\Response::getRequest()` have been removed. Use the event
+  system to work with request and response objects as a transaction.
+- `GuzzleHttp\Message\Response::getRedirectCount()` has been removed. Use the
+  Redirect subscriber instead.
+- `GuzzleHttp\Message\Response::isSuccessful()` and other related methods have
+  been removed. Use `getStatusCode()` instead.
+
+#### Streaming responses
+
+Streaming requests can now be created by a client directly, returning a
+`GuzzleHttp\Message\ResponseInterface` object that contains a body stream
+referencing an open PHP HTTP stream.
+
+```php
+// 3.0
+use Guzzle\Stream\PhpStreamRequestFactory;
+$request = $client->get('/');
+$factory = new PhpStreamRequestFactory();
+$stream = $factory->fromRequest($request);
+$data = $stream->read(1024);
+
+// 4.0
+$response = $client->get('/', ['stream' => true]);
+// Read some data off of the stream in the response body
+$data = $response->getBody()->read(1024);
+```
+
+#### Redirects
+
+The `configureRedirects()` method has been removed in favor of a
+`allow_redirects` request option.
+
+```php
+// Standard redirects with a default of a max of 5 redirects
+$request = $client->createRequest('GET', '/', ['allow_redirects' => true]);
+
+// Strict redirects with a custom number of redirects
+$request = $client->createRequest('GET', '/', [
+    'allow_redirects' => ['max' => 5, 'strict' => true]
+]);
+```
+
+#### EntityBody
+
+EntityBody interfaces and classes have been removed or moved to
+`GuzzleHttp\Stream`. All classes and interfaces that once required
+`GuzzleHttp\EntityBodyInterface` now require
+`GuzzleHttp\Stream\StreamInterface`. Creating a new body for a request no
+longer uses `GuzzleHttp\EntityBody::factory` but now uses
+`GuzzleHttp\Stream\Stream::factory` or even better:
+`GuzzleHttp\Stream\create()`.
+
+- `Guzzle\Http\EntityBodyInterface` is now `GuzzleHttp\Stream\StreamInterface`
+- `Guzzle\Http\EntityBody` is now `GuzzleHttp\Stream\Stream`
+- `Guzzle\Http\CachingEntityBody` is now `GuzzleHttp\Stream\CachingStream`
+- `Guzzle\Http\ReadLimitEntityBody` is now `GuzzleHttp\Stream\LimitStream`
+- `Guzzle\Http\IoEmittyinEntityBody` has been removed.
+
+#### Request lifecycle events
+
+Requests previously submitted a large number of requests. The number of events
+emitted over the lifecycle of a request has been significantly reduced to make
+it easier to understand how to extend the behavior of a request. All events
+emitted during the lifecycle of a request now emit a custom
+`GuzzleHttp\Event\EventInterface` object that contains context providing
+methods and a way in which to modify the transaction at that specific point in
+time (e.g., intercept the request and set a response on the transaction).
+
+- `request.before_send` has been renamed to `before` and now emits a
+  `GuzzleHttp\Event\BeforeEvent`
+- `request.complete` has been renamed to `complete` and now emits a
+  `GuzzleHttp\Event\CompleteEvent`.
+- `request.sent` has been removed. Use `complete`.
+- `request.success` has been removed. Use `complete`.
+- `error` is now an event that emits a `GuzzleHttp\Event\ErrorEvent`.
+- `request.exception` has been removed. Use `error`.
+- `request.receive.status_line` has been removed.
+- `curl.callback.progress` has been removed. Use a custom `StreamInterface` to
+  maintain a status update.
+- `curl.callback.write` has been removed. Use a custom `StreamInterface` to
+  intercept writes.
+- `curl.callback.read` has been removed. Use a custom `StreamInterface` to
+  intercept reads.
+
+`headers` is a new event that is emitted after the response headers of a
+request have been received before the body of the response is downloaded. This
+event emits a `GuzzleHttp\Event\HeadersEvent`.
+
+You can intercept a request and inject a response using the `intercept()` event
+of a `GuzzleHttp\Event\BeforeEvent`, `GuzzleHttp\Event\CompleteEvent`, and
+`GuzzleHttp\Event\ErrorEvent` event.
+
+See: http://docs.guzzlephp.org/en/latest/events.html
+
+## Inflection
+
+The `Guzzle\Inflection` namespace has been removed. This is not a core concern
+of Guzzle.
+
+## Iterator
+
+The `Guzzle\Iterator` namespace has been removed.
+
+- `Guzzle\Iterator\AppendIterator`, `Guzzle\Iterator\ChunkedIterator`, and
+  `Guzzle\Iterator\MethodProxyIterator` are nice, but not a core requirement of
+  Guzzle itself.
+- `Guzzle\Iterator\FilterIterator` is no longer needed because an equivalent
+  class is shipped with PHP 5.4.
+- `Guzzle\Iterator\MapIterator` is not really needed when using PHP 5.5 because
+  it's easier to just wrap an iterator in a generator that maps values.
+
+For a replacement of these iterators, see https://github.com/nikic/iter
+
+## Log
+
+The LogPlugin has moved to https://github.com/guzzle/log-subscriber. The
+`Guzzle\Log` namespace has been removed. Guzzle now relies on
+`Psr\Log\LoggerInterface` for all logging. The MessageFormatter class has been
+moved to `GuzzleHttp\Subscriber\Log\Formatter`.
+
+## Parser
+
+The `Guzzle\Parser` namespace has been removed. This was previously used to
+make it possible to plug in custom parsers for cookies, messages, URI
+templates, and URLs; however, this level of complexity is not needed in Guzzle
+so it has been removed.
+
+- Cookie: Cookie parsing logic has been moved to
+  `GuzzleHttp\Cookie\SetCookie::fromString`.
+- Message: Message parsing logic for both requests and responses has been moved
+  to `GuzzleHttp\Message\MessageFactory::fromMessage`. Message parsing is only
+  used in debugging or deserializing messages, so it doesn't make sense for
+  Guzzle as a library to add this level of complexity to parsing messages.
+- UriTemplate: URI template parsing has been moved to
+  `GuzzleHttp\UriTemplate`. The Guzzle library will automatically use the PECL
+  URI template library if it is installed.
+- Url: URL parsing is now performed in `GuzzleHttp\Url::fromString` (previously
+  it was `Guzzle\Http\Url::factory()`). If custom URL parsing is necessary,
+  then developers are free to subclass `GuzzleHttp\Url`.
+
+## Plugin
+
+The `Guzzle\Plugin` namespace has been renamed to `GuzzleHttp\Subscriber`.
+Several plugins are shipping with the core Guzzle library under this namespace.
+
+- `GuzzleHttp\Subscriber\Cookie`: Replaces the old CookiePlugin. Cookie jar
+  code has moved to `GuzzleHttp\Cookie`.
+- `GuzzleHttp\Subscriber\History`: Replaces the old HistoryPlugin.
+- `GuzzleHttp\Subscriber\HttpError`: Throws errors when a bad HTTP response is
+  received.
+- `GuzzleHttp\Subscriber\Mock`: Replaces the old MockPlugin.
+- `GuzzleHttp\Subscriber\Prepare`: Prepares the body of a request just before
+  sending. This subscriber is attached to all requests by default.
+- `GuzzleHttp\Subscriber\Redirect`: Replaces the RedirectPlugin.
+
+The following plugins have been removed (third-parties are free to re-implement
+these if needed):
+
+- `GuzzleHttp\Plugin\Async` has been removed.
+- `GuzzleHttp\Plugin\CurlAuth` has been removed.
+- `GuzzleHttp\Plugin\ErrorResponse\ErrorResponsePlugin` has been removed. This
+  functionality should instead be implemented with event listeners that occur
+  after normal response parsing occurs in the guzzle/command package.
+
+The following plugins are not part of the core Guzzle package, but are provided
+in separate repositories:
+
+- `Guzzle\Http\Plugin\BackoffPlugin` has been rewritten to be much simpler
+  to build custom retry policies using simple functions rather than various
+  chained classes. See: https://github.com/guzzle/retry-subscriber
+- `Guzzle\Http\Plugin\Cache\CachePlugin` has moved to
+  https://github.com/guzzle/cache-subscriber
+- `Guzzle\Http\Plugin\Log\LogPlugin` has moved to
+  https://github.com/guzzle/log-subscriber
+- `Guzzle\Http\Plugin\Md5\Md5Plugin` has moved to
+  https://github.com/guzzle/message-integrity-subscriber
+- `Guzzle\Http\Plugin\Mock\MockPlugin` has moved to
+  `GuzzleHttp\Subscriber\MockSubscriber`.
+- `Guzzle\Http\Plugin\Oauth\OauthPlugin` has moved to
+  https://github.com/guzzle/oauth-subscriber
+
+## Service
+
+The service description layer of Guzzle has moved into two separate packages:
+
+- http://github.com/guzzle/command Provides a high level abstraction over web
+  services by representing web service operations using commands.
+- http://github.com/guzzle/guzzle-services Provides an implementation of
+  guzzle/command that provides request serialization and response parsing using
+  Guzzle service descriptions.
+
+## Stream
+
+Stream have moved to a separate package available at
+https://github.com/guzzle/streams.
+
+`Guzzle\Stream\StreamInterface` has been given a large update to cleanly take
+on the responsibilities of `Guzzle\Http\EntityBody` and
+`Guzzle\Http\EntityBodyInterface` now that they have been removed. The number
+of methods implemented by the `StreamInterface` has been drastically reduced to
+allow developers to more easily extend and decorate stream behavior.
+
+## Removed methods from StreamInterface
+
+- `getStream` and `setStream` have been removed to better encapsulate streams.
+- `getMetadata` and `setMetadata` have been removed in favor of
+  `GuzzleHttp\Stream\MetadataStreamInterface`.
+- `getWrapper`, `getWrapperData`, `getStreamType`, and `getUri` have all been
+  removed. This data is accessible when
+  using streams that implement `GuzzleHttp\Stream\MetadataStreamInterface`.
+- `rewind` has been removed. Use `seek(0)` for a similar behavior.
+
+## Renamed methods
+
+- `detachStream` has been renamed to `detach`.
+- `feof` has been renamed to `eof`.
+- `ftell` has been renamed to `tell`.
+- `readLine` has moved from an instance method to a static class method of
+  `GuzzleHttp\Stream\Stream`.
+
+## Metadata streams
+
+`GuzzleHttp\Stream\MetadataStreamInterface` has been added to denote streams
+that contain additional metadata accessible via `getMetadata()`.
+`GuzzleHttp\Stream\StreamInterface::getMetadata` and
+`GuzzleHttp\Stream\StreamInterface::setMetadata` have been removed.
+
+## StreamRequestFactory
+
+The entire concept of the StreamRequestFactory has been removed. The way this
+was used in Guzzle 3 broke the actual interface of sending streaming requests
+(instead of getting back a Response, you got a StreamInterface). Streaming
+PHP requests are now implemented through the `GuzzleHttp\Adapter\StreamAdapter`.
+
+3.6 to 3.7
+----------
+
+### Deprecations
+
+- You can now enable E_USER_DEPRECATED warnings to see if you are using any deprecated methods.:
+
+```php
+\Guzzle\Common\Version::$emitWarnings = true;
+```
+
+The following APIs and options have been marked as deprecated:
+
+- Marked `Guzzle\Http\Message\Request::isResponseBodyRepeatable()` as deprecated. Use `$request->getResponseBody()->isRepeatable()` instead.
+- Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
+- Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
+- Marked `Guzzle\Http\Message\Request::setIsRedirect()` as deprecated. Use the HistoryPlugin instead.
+- Marked `Guzzle\Http\Message\Request::isRedirect()` as deprecated. Use the HistoryPlugin instead.
+- Marked `Guzzle\Cache\CacheAdapterFactory::factory()` as deprecated
+- Marked `Guzzle\Service\Client::enableMagicMethods()` as deprecated. Magic methods can no longer be disabled on a Guzzle\Service\Client.
+- Marked `Guzzle\Parser\Url\UrlParser` as deprecated. Just use PHP's `parse_url()` and percent encode your UTF-8.
+- Marked `Guzzle\Common\Collection::inject()` as deprecated.
+- Marked `Guzzle\Plugin\CurlAuth\CurlAuthPlugin` as deprecated. Use
+  `$client->getConfig()->setPath('request.options/auth', array('user', 'pass', 'Basic|Digest|NTLM|Any'));` or
+  `$client->setDefaultOption('auth', array('user', 'pass', 'Basic|Digest|NTLM|Any'));`
+
+3.7 introduces `request.options` as a parameter for a client configuration and as an optional argument to all creational
+request methods. When paired with a client's configuration settings, these options allow you to specify default settings
+for various aspects of a request. Because these options make other previous configuration options redundant, several
+configuration options and methods of a client and AbstractCommand have been deprecated.
+
+- Marked `Guzzle\Service\Client::getDefaultHeaders()` as deprecated. Use `$client->getDefaultOption('headers')`.
+- Marked `Guzzle\Service\Client::setDefaultHeaders()` as deprecated. Use `$client->setDefaultOption('headers/{header_name}', 'value')`.
+- Marked 'request.params' for `Guzzle\Http\Client` as deprecated. Use `$client->setDefaultOption('params/{param_name}', 'value')`
+- Marked 'command.headers', 'command.response_body' and 'command.on_complete' as deprecated for AbstractCommand. These will work through Guzzle 4.0
+
+        $command = $client->getCommand('foo', array(
+            'command.headers' => array('Test' => '123'),
+            'command.response_body' => '/path/to/file'
+        ));
+
+        // Should be changed to:
+
+        $command = $client->getCommand('foo', array(
+            'command.request_options' => array(
+                'headers' => array('Test' => '123'),
+                'save_as' => '/path/to/file'
+            )
+        ));
+
+### Interface changes
+
+Additions and changes (you will need to update any implementations or subclasses you may have created):
+
+- Added an `$options` argument to the end of the following methods of `Guzzle\Http\ClientInterface`:
+  createRequest, head, delete, put, patch, post, options, prepareRequest
+- Added an `$options` argument to the end of `Guzzle\Http\Message\Request\RequestFactoryInterface::createRequest()`
+- Added an `applyOptions()` method to `Guzzle\Http\Message\Request\RequestFactoryInterface`
+- Changed `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $body = null)` to
+  `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $options = array())`. You can still pass in a
+  resource, string, or EntityBody into the $options parameter to specify the download location of the response.
+- Changed `Guzzle\Common\Collection::__construct($data)` to no longer accepts a null value for `$data` but a
+  default `array()`
+- Added `Guzzle\Stream\StreamInterface::isRepeatable`
+- Made `Guzzle\Http\Client::expandTemplate` and `getUriTemplate` protected methods.
+
+The following methods were removed from interfaces. All of these methods are still available in the concrete classes
+that implement them, but you should update your code to use alternative methods:
+
+- Removed `Guzzle\Http\ClientInterface::setDefaultHeaders(). Use
+  `$client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`. or
+  `$client->getConfig()->setPath('request.options/headers', array('header_name' => 'value'))` or
+  `$client->setDefaultOption('headers/{header_name}', 'value')`. or
+  `$client->setDefaultOption('headers', array('header_name' => 'value'))`.
+- Removed `Guzzle\Http\ClientInterface::getDefaultHeaders(). Use `$client->getConfig()->getPath('request.options/headers')`.
+- Removed `Guzzle\Http\ClientInterface::expandTemplate()`. This is an implementation detail.
+- Removed `Guzzle\Http\ClientInterface::setRequestFactory()`. This is an implementation detail.
+- Removed `Guzzle\Http\ClientInterface::getCurlMulti()`. This is a very specific implementation detail.
+- Removed `Guzzle\Http\Message\RequestInterface::canCache`. Use the CachePlugin.
+- Removed `Guzzle\Http\Message\RequestInterface::setIsRedirect`. Use the HistoryPlugin.
+- Removed `Guzzle\Http\Message\RequestInterface::isRedirect`. Use the HistoryPlugin.
+
+### Cache plugin breaking changes
+
+- CacheKeyProviderInterface and DefaultCacheKeyProvider are no longer used. All of this logic is handled in a
+  CacheStorageInterface. These two objects and interface will be removed in a future version.
+- Always setting X-cache headers on cached responses
+- Default cache TTLs are now handled by the CacheStorageInterface of a CachePlugin
+- `CacheStorageInterface::cache($key, Response $response, $ttl = null)` has changed to `cache(RequestInterface
+  $request, Response $response);`
+- `CacheStorageInterface::fetch($key)` has changed to `fetch(RequestInterface $request);`
+- `CacheStorageInterface::delete($key)` has changed to `delete(RequestInterface $request);`
+- Added `CacheStorageInterface::purge($url)`
+- `DefaultRevalidation::__construct(CacheKeyProviderInterface $cacheKey, CacheStorageInterface $cache, CachePlugin
+  $plugin)` has changed to `DefaultRevalidation::__construct(CacheStorageInterface $cache,
+  CanCacheStrategyInterface $canCache = null)`
+- Added `RevalidationInterface::shouldRevalidate(RequestInterface $request, Response $response)`
+
+3.5 to 3.6
+----------
+
+* Mixed casing of headers are now forced to be a single consistent casing across all values for that header.
+* Messages internally use a HeaderCollection object to delegate handling case-insensitive header resolution
+* Removed the whole changedHeader() function system of messages because all header changes now go through addHeader().
+  For example, setHeader() first removes the header using unset on a HeaderCollection and then calls addHeader().
+  Keeping the Host header and URL host in sync is now handled by overriding the addHeader method in Request.
+* Specific header implementations can be created for complex headers. When a message creates a header, it uses a
+  HeaderFactory which can map specific headers to specific header classes. There is now a Link header and
+  CacheControl header implementation.
+* Moved getLinks() from Response to just be used on a Link header object.
+
+If you previously relied on Guzzle\Http\Message\Header::raw(), then you will need to update your code to use the
+HeaderInterface (e.g. toArray(), getAll(), etc.).
+
+### Interface changes
+
+* Removed from interface: Guzzle\Http\ClientInterface::setUriTemplate
+* Removed from interface: Guzzle\Http\ClientInterface::setCurlMulti()
+* Removed Guzzle\Http\Message\Request::receivedRequestHeader() and implemented this functionality in
+  Guzzle\Http\Curl\RequestMediator
+* Removed the optional $asString parameter from MessageInterface::getHeader(). Just cast the header to a string.
+* Removed the optional $tryChunkedTransfer option from Guzzle\Http\Message\EntityEnclosingRequestInterface
+* Removed the $asObjects argument from Guzzle\Http\Message\MessageInterface::getHeaders()
+
+### Removed deprecated functions
+
+* Removed Guzzle\Parser\ParserRegister::get(). Use getParser()
+* Removed Guzzle\Parser\ParserRegister::set(). Use registerParser().
+
+### Deprecations
+
+* The ability to case-insensitively search for header values
+* Guzzle\Http\Message\Header::hasExactHeader
+* Guzzle\Http\Message\Header::raw. Use getAll()
+* Deprecated cache control specific methods on Guzzle\Http\Message\AbstractMessage. Use the CacheControl header object
+  instead.
+
+### Other changes
+
+* All response header helper functions return a string rather than mixing Header objects and strings inconsistently
+* Removed cURL blacklist support. This is no longer necessary now that Expect, Accept, etc. are managed by Guzzle
+  directly via interfaces
+* Removed the injecting of a request object onto a response object. The methods to get and set a request still exist
+  but are a no-op until removed.
+* Most classes that used to require a `Guzzle\Service\Command\CommandInterface` typehint now request a
+  `Guzzle\Service\Command\ArrayCommandInterface`.
+* Added `Guzzle\Http\Message\RequestInterface::startResponse()` to the RequestInterface to handle injecting a response
+  on a request while the request is still being transferred
+* `Guzzle\Service\Command\CommandInterface` now extends from ToArrayInterface and ArrayAccess
+
+3.3 to 3.4
+----------
+
+Base URLs of a client now follow the rules of http://tools.ietf.org/html/rfc3986#section-5.2.2 when merging URLs.
+
+3.2 to 3.3
+----------
+
+### Response::getEtag() quote stripping removed
+
+`Guzzle\Http\Message\Response::getEtag()` no longer strips quotes around the ETag response header
+
+### Removed `Guzzle\Http\Utils`
+
+The `Guzzle\Http\Utils` class was removed. This class was only used for testing.
+
+### Stream wrapper and type
+
+`Guzzle\Stream\Stream::getWrapper()` and `Guzzle\Stream\Stream::getStreamType()` are no longer converted to lowercase.
+
+### curl.emit_io became emit_io
+
+Emitting IO events from a RequestMediator is now a parameter that must be set in a request's curl options using the
+'emit_io' key. This was previously set under a request's parameters using 'curl.emit_io'
+
+3.1 to 3.2
+----------
+
+### CurlMulti is no longer reused globally
+
+Before 3.2, the same CurlMulti object was reused globally for each client. This can cause issue where plugins added
+to a single client can pollute requests dispatched from other clients.
+
+If you still wish to reuse the same CurlMulti object with each client, then you can add a listener to the
+ServiceBuilder's `service_builder.create_client` event to inject a custom CurlMulti object into each client as it is
+created.
+
+```php
+$multi = new Guzzle\Http\Curl\CurlMulti();
+$builder = Guzzle\Service\Builder\ServiceBuilder::factory('/path/to/config.json');
+$builder->addListener('service_builder.create_client', function ($event) use ($multi) {
+    $event['client']->setCurlMulti($multi);
+}
+});
+```
+
+### No default path
+
+URLs no longer have a default path value of '/' if no path was specified.
+
+Before:
+
+```php
+$request = $client->get('http://www.foo.com');
+echo $request->getUrl();
+// >> http://www.foo.com/
+```
+
+After:
+
+```php
+$request = $client->get('http://www.foo.com');
+echo $request->getUrl();
+// >> http://www.foo.com
+```
+
+### Less verbose BadResponseException
+
+The exception message for `Guzzle\Http\Exception\BadResponseException` no longer contains the full HTTP request and
+response information. You can, however, get access to the request and response object by calling `getRequest()` or
+`getResponse()` on the exception object.
+
+### Query parameter aggregation
+
+Multi-valued query parameters are no longer aggregated using a callback function. `Guzzle\Http\Query` now has a
+setAggregator() method that accepts a `Guzzle\Http\QueryAggregator\QueryAggregatorInterface` object. This object is
+responsible for handling the aggregation of multi-valued query string variables into a flattened hash.
+
+2.8 to 3.x
+----------
+
+### Guzzle\Service\Inspector
+
+Change `\Guzzle\Service\Inspector::fromConfig` to `\Guzzle\Common\Collection::fromConfig`
+
+**Before**
+
+```php
+use Guzzle\Service\Inspector;
+
+class YourClient extends \Guzzle\Service\Client
+{
+    public static function factory($config = array())
+    {
+        $default = array();
+        $required = array('base_url', 'username', 'api_key');
+        $config = Inspector::fromConfig($config, $default, $required);
+
+        $client = new self(
+            $config->get('base_url'),
+            $config->get('username'),
+            $config->get('api_key')
+        );
+        $client->setConfig($config);
+
+        $client->setDescription(ServiceDescription::factory(__DIR__ . DIRECTORY_SEPARATOR . 'client.json'));
+
+        return $client;
+    }
+```
+
+**After**
+
+```php
+use Guzzle\Common\Collection;
+
+class YourClient extends \Guzzle\Service\Client
+{
+    public static function factory($config = array())
+    {
+        $default = array();
+        $required = array('base_url', 'username', 'api_key');
+        $config = Collection::fromConfig($config, $default, $required);
+
+        $client = new self(
+            $config->get('base_url'),
+            $config->get('username'),
+            $config->get('api_key')
+        );
+        $client->setConfig($config);
+
+        $client->setDescription(ServiceDescription::factory(__DIR__ . DIRECTORY_SEPARATOR . 'client.json'));
+
+        return $client;
+    }
+```
+
+### Convert XML Service Descriptions to JSON
+
+**Before**
+
+```xml

+
+### Guzzle\Service\Description\ServiceDescription
+
+Commands are now called Operations
+
+**Before**
+
+```php
+use Guzzle\Service\Description\ServiceDescription;
+
+$sd = new ServiceDescription();
+$sd->getCommands();     // @returns ApiCommandInterface[]
+$sd->hasCommand($name);
+$sd->getCommand($name); // @returns ApiCommandInterface|null
+$sd->addCommand($command); // @param ApiCommandInterface $command
+```
+
+**After**
+
+```php
+use Guzzle\Service\Description\ServiceDescription;
+
+$sd = new ServiceDescription();
+$sd->getOperations();           // @returns OperationInterface[]
+$sd->hasOperation($name);
+$sd->getOperation($name);       // @returns OperationInterface|null
+$sd->addOperation($operation);  // @param OperationInterface $operation
+```
+
+### Guzzle\Common\Inflection\Inflector
+
+Namespace is now `Guzzle\Inflection\Inflector`
+
+### Guzzle\Http\Plugin
+
+Namespace is now `Guzzle\Plugin`. Many other changes occur within this namespace and are detailed in their own sections below.
+
+### Guzzle\Http\Plugin\LogPlugin and Guzzle\Common\Log
+
+Now `Guzzle\Plugin\Log\LogPlugin` and `Guzzle\Log` respectively.
+
+**Before**
+
+```php
+use Guzzle\Common\Log\ClosureLogAdapter;
+use Guzzle\Http\Plugin\LogPlugin;
+
+/** @var \Guzzle\Http\Client */
+$client;
+
+// $verbosity is an integer indicating desired message verbosity level
+$client->addSubscriber(new LogPlugin(new ClosureLogAdapter(function($m) { echo $m; }, $verbosity = LogPlugin::LOG_VERBOSE);
+```
+
+**After**
+
+```php
+use Guzzle\Log\ClosureLogAdapter;
+use Guzzle\Log\MessageFormatter;
+use Guzzle\Plugin\Log\LogPlugin;
+
+/** @var \Guzzle\Http\Client */
+$client;
+
+// $format is a string indicating desired message format -- @see MessageFormatter
+$client->addSubscriber(new LogPlugin(new ClosureLogAdapter(function($m) { echo $m; }, $format = MessageFormatter::DEBUG_FORMAT);
+```
+
+### Guzzle\Http\Plugin\CurlAuthPlugin
+
+Now `Guzzle\Plugin\CurlAuth\CurlAuthPlugin`.
+
+### Guzzle\Http\Plugin\ExponentialBackoffPlugin
+
+Now `Guzzle\Plugin\Backoff\BackoffPlugin`, and other changes.
+
+**Before**
+
+```php
+use Guzzle\Http\Plugin\ExponentialBackoffPlugin;
+
+$backoffPlugin = new ExponentialBackoffPlugin($maxRetries, array_merge(
+        ExponentialBackoffPlugin::getDefaultFailureCodes(), array(429)
+    ));
+
+$client->addSubscriber($backoffPlugin);
+```
+
+**After**
+
+```php
+use Guzzle\Plugin\Backoff\BackoffPlugin;
+use Guzzle\Plugin\Backoff\HttpBackoffStrategy;
+
+// Use convenient factory method instead -- see implementation for ideas of what
+// you can do with chaining backoff strategies
+$backoffPlugin = BackoffPlugin::getExponentialBackoff($maxRetries, array_merge(
+        HttpBackoffStrategy::getDefaultFailureCodes(), array(429)
+    ));
+$client->addSubscriber($backoffPlugin);
+```
+
+### Known Issues
+
+#### [BUG] Accept-Encoding header behavior changed unintentionally.
+
+(See #217) (Fixed in 09daeb8c666fb44499a0646d655a8ae36456575e)
+
+In version 2.8 setting the `Accept-Encoding` header would set the CURLOPT_ENCODING option, which permitted cURL to
+properly handle gzip/deflate compressed responses from the server. In versions affected by this bug this does not happen.
+See issue #217 for a workaround, or use a version containing the fix.

+# Features
+
+- [Promises/A+](https://promisesaplus.com/) implementation.
+- Promise resolution and chaining is handled iteratively, allowing for
+  "infinite" promise chaining.
+- Promises have a synchronous `wait` method.
+- Promises can be cancelled.
+- Works with any object that has a `then` function.
+- C# style async/await coroutine promises using
+  `GuzzleHttp\Promise\coroutine()`.
+
+
+# Quick start
+
+A *promise* represents the eventual result of an asynchronous operation. The
+primary way of interacting with a promise is through its `then` method, which
+registers callbacks to receive either a promise's eventual value or the reason
+why the promise cannot be fulfilled.
+
+
+## Callbacks
+
+Callbacks are registered with the `then` method by providing an optional 
+`$onFulfilled` followed by an optional `$onRejected` function.
+
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise->then(
+    // $onFulfilled
+    function ($value) {
+        echo 'The promise was fulfilled.';
+    },
+    // $onRejected
+    function ($reason) {
+        echo 'The promise was rejected.';
+    }
+);
+```
+
+*Resolving* a promise means that you either fulfill a promise with a *value* or
+reject a promise with a *reason*. Resolving a promises triggers callbacks
+registered with the promises's `then` method. These callbacks are triggered
+only once and in the order in which they were added.
+
+
+## Resolving a promise
+
+Promises are fulfilled using the `resolve($value)` method. Resolving a promise
+with any value other than a `GuzzleHttp\Promise\RejectedPromise` will trigger
+all of the onFulfilled callbacks (resolving a promise with a rejected promise
+will reject the promise and trigger the `$onRejected` callbacks).
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise
+    ->then(function ($value) {
+        // Return a value and don't break the chain
+        return "Hello, " . $value;
+    })
+    // This then is executed after the first then and receives the value
+    // returned from the first then.
+    ->then(function ($value) {
+        echo $value;
+    });
+
+// Resolving the promise triggers the $onFulfilled callbacks and outputs
+// "Hello, reader".
+$promise->resolve('reader.');
+```
+
+
+## Promise forwarding
+
+Promises can be chained one after the other. Each then in the chain is a new
+promise. The return value of a promise is what's forwarded to the next
+promise in the chain. Returning a promise in a `then` callback will cause the
+subsequent promises in the chain to only be fulfilled when the returned promise
+has been fulfilled. The next promise in the chain will be invoked with the
+resolved value of the promise.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$nextPromise = new Promise();
+
+$promise
+    ->then(function ($value) use ($nextPromise) {
+        echo $value;
+        return $nextPromise;
+    })
+    ->then(function ($value) {
+        echo $value;
+    });
+
+// Triggers the first callback and outputs "A"
+$promise->resolve('A');
+// Triggers the second callback and outputs "B"
+$nextPromise->resolve('B');
+```
+
+## Promise rejection
+
+When a promise is rejected, the `$onRejected` callbacks are invoked with the
+rejection reason.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise->then(null, function ($reason) {
+    echo $reason;
+});
+
+$promise->reject('Error!');
+// Outputs "Error!"
+```
+
+## Rejection forwarding
+
+If an exception is thrown in an `$onRejected` callback, subsequent
+`$onRejected` callbacks are invoked with the thrown exception as the reason.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise->then(null, function ($reason) {
+    throw new \Exception($reason);
+})->then(null, function ($reason) {
+    assert($reason->getMessage() === 'Error!');
+});
+
+$promise->reject('Error!');
+```
+
+You can also forward a rejection down the promise chain by returning a
+`GuzzleHttp\Promise\RejectedPromise` in either an `$onFulfilled` or
+`$onRejected` callback.
+
+```php
+use GuzzleHttp\Promise\Promise;
+use GuzzleHttp\Promise\RejectedPromise;
+
+$promise = new Promise();
+$promise->then(null, function ($reason) {
+    return new RejectedPromise($reason);
+})->then(null, function ($reason) {
+    assert($reason === 'Error!');
+});
+
+$promise->reject('Error!');
+```
+
+If an exception is not thrown in a `$onRejected` callback and the callback
+does not return a rejected promise, downstream `$onFulfilled` callbacks are
+invoked using the value returned from the `$onRejected` callback.
+
+```php
+use GuzzleHttp\Promise\Promise;
+use GuzzleHttp\Promise\RejectedPromise;
+
+$promise = new Promise();
+$promise
+    ->then(null, function ($reason) {
+        return "It's ok";
+    })
+    ->then(function ($value) {
+        assert($value === "It's ok");
+    });
+
+$promise->reject('Error!');
+```
+
+# Synchronous wait
+
+You can synchronously force promises to complete using a promise's `wait`
+method. When creating a promise, you can provide a wait function that is used
+to synchronously force a promise to complete. When a wait function is invoked
+it is expected to deliver a value to the promise or reject the promise. If the
+wait function does not deliver a value, then an exception is thrown. The wait
+function provided to a promise constructor is invoked when the `wait` function
+of the promise is called.
+
+```php
+$promise = new Promise(function () use (&$promise) {
+    $promise->resolve('foo');
+});
+
+// Calling wait will return the value of the promise.
+echo $promise->wait(); // outputs "foo"
+```
+
+If an exception is encountered while invoking the wait function of a promise,
+the promise is rejected with the exception and the exception is thrown.
+
+```php
+$promise = new Promise(function () use (&$promise) {
+    throw new \Exception('foo');
+});
+
+$promise->wait(); // throws the exception.
+```
+
+Calling `wait` on a promise that has been fulfilled will not trigger the wait
+function. It will simply return the previously resolved value.
+
+```php
+$promise = new Promise(function () { die('this is not called!'); });
+$promise->resolve('foo');
+echo $promise->wait(); // outputs "foo"
+```
+
+Calling `wait` on a promise that has been rejected will throw an exception. If
+the rejection reason is an instance of `\Exception` the reason is thrown.
+Otherwise, a `GuzzleHttp\Promise\RejectionException` is thrown and the reason
+can be obtained by calling the `getReason` method of the exception.
+
+```php
+$promise = new Promise();
+$promise->reject('foo');
+$promise->wait();
+```
+
+> PHP Fatal error:  Uncaught exception 'GuzzleHttp\Promise\RejectionException' with message 'The promise was rejected with value: foo'
+
+
+## Unwrapping a promise
+
+When synchronously waiting on a promise, you are joining the state of the
+promise into the current state of execution (i.e., return the value of the
+promise if it was fulfilled or throw an exception if it was rejected). This is
+called "unwrapping" the promise. Waiting on a promise will by default unwrap
+the promise state.
+
+You can force a promise to resolve and *not* unwrap the state of the promise
+by passing `false` to the first argument of the `wait` function:
+
+```php
+$promise = new Promise();
+$promise->reject('foo');
+// This will not throw an exception. It simply ensures the promise has
+// been resolved.
+$promise->wait(false);
+```
+
+When unwrapping a promise, the resolved value of the promise will be waited
+upon until the unwrapped value is not a promise. This means that if you resolve
+promise A with a promise B and unwrap promise A, the value returned by the
+wait function will be the value delivered to promise B.
+
+**Note**: when you do not unwrap the promise, no value is returned.
+
+
+# Cancellation
+
+You can cancel a promise that has not yet been fulfilled using the `cancel()`
+method of a promise. When creating a promise you can provide an optional
+cancel function that when invoked cancels the action of computing a resolution
+of the promise.
+
+
+# API
+
+
+## Promise
+
+When creating a promise object, you can provide an optional `$waitFn` and
+`$cancelFn`. `$waitFn` is a function that is invoked with no arguments and is
+expected to resolve the promise. `$cancelFn` is a function with no arguments
+that is expected to cancel the computation of a promise. It is invoked when the
+`cancel()` method of a promise is called.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise(
+    function () use (&$promise) {
+        $promise->resolve('waited');
+    },
+    function () {
+        // do something that will cancel the promise computation (e.g., close
+        // a socket, cancel a database query, etc...)
+    }
+);
+
+assert('waited' === $promise->wait());
+```
+
+A promise has the following methods:
+
+- `then(callable $onFulfilled, callable $onRejected) : PromiseInterface`
+  
+  Appends fulfillment and rejection handlers to the promise, and returns a new promise resolving to the return value of the called handler.
+
+- `otherwise(callable $onRejected) : PromiseInterface`
+  
+  Appends a rejection handler callback to the promise, and returns a new promise resolving to the return value of the callback if it is called, or to its original fulfillment value if the promise is instead fulfilled.
+
+- `wait($unwrap = true) : mixed`
+
+  Synchronously waits on the promise to complete.
+  
+  `$unwrap` controls whether or not the value of the promise is returned for a
+  fulfilled promise or if an exception is thrown if the promise is rejected.
+  This is set to `true` by default.
+
+- `cancel()`
+
+  Attempts to cancel the promise if possible. The promise being cancelled and
+  the parent most ancestor that has not yet been resolved will also be
+  cancelled. Any promises waiting on the cancelled promise to resolve will also
+  be cancelled.
+
+- `getState() : string`
+
+  Returns the state of the promise. One of `pending`, `fulfilled`, or
+  `rejected`.
+
+- `resolve($value)`
+
+  Fulfills the promise with the given `$value`.
+
+- `reject($reason)`
+
+  Rejects the promise with the given `$reason`.
+
+
+## FulfilledPromise
+
+A fulfilled promise can be created to represent a promise that has been
+fulfilled.
+
+```php
+use GuzzleHttp\Promise\FulfilledPromise;
+
+$promise = new FulfilledPromise('value');
+
+// Fulfilled callbacks are immediately invoked.
+$promise->then(function ($value) {
+    echo $value;
+});
+```
+
+
+## RejectedPromise
+
+A rejected promise can be created to represent a promise that has been
+rejected.
+
+```php
+use GuzzleHttp\Promise\RejectedPromise;
+
+$promise = new RejectedPromise('Error');
+
+// Rejected callbacks are immediately invoked.
+$promise->then(null, function ($reason) {
+    echo $reason;
+});
+```
+
+
+# Promise interop
+
+This library works with foreign promises that have a `then` method. This means
+you can use Guzzle promises with [React promises](https://github.com/reactphp/promise)
+for example. When a foreign promise is returned inside of a then method
+callback, promise resolution will occur recursively.
+
+```php
+// Create a React promise
+$deferred = new React\Promise\Deferred();
+$reactPromise = $deferred->promise();
+
+// Create a Guzzle promise that is fulfilled with a React promise.
+$guzzlePromise = new \GuzzleHttp\Promise\Promise();
+$guzzlePromise->then(function ($value) use ($reactPromise) {
+    // Do something something with the value...
+    // Return the React promise
+    return $reactPromise;
+});
+```
+
+Please note that wait and cancel chaining is no longer possible when forwarding
+a foreign promise. You will need to wrap a third-party promise with a Guzzle
+promise in order to utilize wait and cancel functions with foreign promises.
+
+
+## Event Loop Integration
+
+In order to keep the stack size constant, Guzzle promises are resolved
+asynchronously using a task queue. When waiting on promises synchronously, the
+task queue will be automatically run to ensure that the blocking promise and
+any forwarded promises are resolved. When using promises asynchronously in an
+event loop, you will need to run the task queue on each tick of the loop. If
+you do not run the task queue, then promises will not be resolved.
+
+You can run the task queue using the `run()` method of the global task queue
+instance.
+
+```php
+// Get the global task queue
+$queue = \GuzzleHttp\Promise\queue();
+$queue->run();
+```
+
+For example, you could use Guzzle promises with React using a periodic timer:
+
+```php
+$loop = React\EventLoop\Factory::create();
+$loop->addPeriodicTimer(0, [$queue, 'run']);
+```
+
+*TODO*: Perhaps adding a `futureTick()` on each tick would be faster?
+
+
+# Implementation notes
+
+
+## Promise resolution and chaining is handled iteratively
+
+By shuffling pending handlers from one owner to another, promises are
+resolved iteratively, allowing for "infinite" then chaining.
+
+```php
+<?php
+require 'vendor/autoload.php';
+
+use GuzzleHttp\Promise\Promise;
+
+$parent = new Promise();
+$p = $parent;
+
+for ($i = 0; $i < 1000; $i++) {
+    $p = $p->then(function ($v) {
+        // The stack size remains constant (a good thing)
+        echo xdebug_get_stack_depth() . ', ';
+        return $v + 1;
+    });
+}
+
+$parent->resolve(0);
+var_dump($p->wait()); // int(1000)
+
+```
+
+When a promise is fulfilled or rejected with a non-promise value, the promise
+then takes ownership of the handlers of each child promise and delivers values
+down the chain without using recursion.
+
+When a promise is resolved with another promise, the original promise transfers
+all of its pending handlers to the new promise. When the new promise is
+eventually resolved, all of the pending handlers are delivered the forwarded
+value.
+
+
+## A promise is the deferred.
+
+Some promise libraries implement promises using a deferred object to represent
+a computation and a promise object to represent the delivery of the result of
+the computation. This is a nice separation of computation and delivery because
+consumers of the promise cannot modify the value that will be eventually
+delivered.
+
+One side effect of being able to implement promise resolution and chaining
+iteratively is that you need to be able for one promise to reach into the state
+of another promise to shuffle around ownership of handlers. In order to achieve
+this without making the handlers of a promise publicly mutable, a promise is
+also the deferred value, allowing promises of the same parent class to reach
+into and modify the private properties of promises of the same type. While this
+does allow consumers of the value to modify the resolution or rejection of the
+deferred, it is a small price to pay for keeping the stack size constant.
+
+```php
+$promise = new Promise();
+$promise->then(function ($value) { echo $value; });
+// The promise is the deferred value, so you can deliver a value to it.
+$promise->resolve('foo');
+// prints "foo"
+```

+# Change Log
+
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
+and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html).
+
+
+## [Unreleased]
+
+
+## [1.6.0]
+
+### Added
+
+- Allowed version `^3.0` of `ralouphie/getallheaders` dependency (#244)
+- Added MIME type for WEBP image format (#246)
+- Added more validation of values according to PSR-7 and RFC standards, e.g. status code range (#250, #272)
+
+### Changed
+
+- Tests don't pass with HHVM 4.0, so HHVM support got dropped. Other libraries like composer have done the same. (#262)
+- Accept port number 0 to be valid (#270)
+
+### Fixed
+
+- Fixed subsequent reads from `php://input` in ServerRequest (#247)
+- Fixed readable/writable detection for certain stream modes (#248)
+- Fixed encoding of special characters in the `userInfo` component of an URI (#253)
+
+
+## [1.5.2] - 2018-12-04
+
+### Fixed
+
+- Check body size when getting the message summary
+
+
+## [1.5.1] - 2018-12-04
+
+### Fixed
+
+- Get the summary of a body only if it is readable
+
+
+## [1.5.0] - 2018-12-03
+
+### Added
+
+- Response first-line to response string exception (fixes #145)
+- A test for #129 behavior
+- `get_message_body_summary` function in order to get the message summary
+- `3gp` and `mkv` mime types
+
+### Changed
+
+- Clarify exception message when stream is detached
+
+### Deprecated
+
+- Deprecated parsing folded header lines as per RFC 7230
+
+### Fixed
+
+- Fix `AppendStream::detach` to not close streams
+- `InflateStream` preserves `isSeekable` attribute of the underlying stream
+- `ServerRequest::getUriFromGlobals` to support URLs in query parameters
+
+
+Several other fixes and improvements.
+
+
+## [1.4.2] - 2017-03-20
+
+### Fixed
+
+- Reverted BC break to `Uri::resolve` and `Uri::removeDotSegments` by removing
+  calls to `trigger_error` when deprecated methods are invoked.
+
+
+## [1.4.1] - 2017-02-27
+
+### Added
+
+- Rriggering of silenced deprecation warnings.
+
+### Fixed
+
+- Reverted BC break by reintroducing behavior to automagically fix a URI with a
+  relative path and an authority by adding a leading slash to the path. It's only
+  deprecated now.
+
+
+## [1.4.0] - 2017-02-21
+
+### Added
+
+- Added common URI utility methods based on RFC 3986 (see documentation in the readme):
+  - `Uri::isDefaultPort`
+  - `Uri::isAbsolute`
+  - `Uri::isNetworkPathReference`
+  - `Uri::isAbsolutePathReference`
+  - `Uri::isRelativePathReference`
+  - `Uri::isSameDocumentReference`
+  - `Uri::composeComponents`
+  - `UriNormalizer::normalize`
+  - `UriNormalizer::isEquivalent`
+  - `UriResolver::relativize`
+
+### Changed
+
+- Ensure `ServerRequest::getUriFromGlobals` returns a URI in absolute form.
+- Allow `parse_response` to parse a response without delimiting space and reason.
+- Ensure each URI modification results in a valid URI according to PSR-7 discussions.
+  Invalid modifications will throw an exception instead of returning a wrong URI or
+  doing some magic.
+  - `(new Uri)->withPath('foo')->withHost('example.com')` will throw an exception
+    because the path of a URI with an authority must start with a slash "/" or be empty
+  - `(new Uri())->withScheme('http')` will return `'http://localhost'`
+
+### Deprecated
+
+- `Uri::resolve` in favor of `UriResolver::resolve`
+- `Uri::removeDotSegments` in favor of `UriResolver::removeDotSegments`
+
+### Fixed
+
+- `Stream::read` when length parameter <= 0.
+- `copy_to_stream` reads bytes in chunks instead of `maxLen` into memory.
+- `ServerRequest::getUriFromGlobals` when `Host` header contains port.
+- Compatibility of URIs with `file` scheme and empty host.
+
+
+## [1.3.1] - 2016-06-25
+
+### Fixed
+
+- `Uri::__toString` for network path references, e.g. `//example.org`.
+- Missing lowercase normalization for host.
+- Handling of URI components in case they are `'0'` in a lot of places,
+  e.g. as a user info password.
+- `Uri::withAddedHeader` to correctly merge headers with different case.
+- Trimming of header values in `Uri::withAddedHeader`. Header values may
+  be surrounded by whitespace which should be ignored according to RFC 7230
+  Section 3.2.4. This does not apply to header names.
+- `Uri::withAddedHeader` with an array of header values.
+- `Uri::resolve` when base path has no slash and handling of fragment.
+- Handling of encoding in `Uri::with(out)QueryValue` so one can pass the
+  key/value both in encoded as well as decoded form to those methods. This is
+  consistent with withPath, withQuery etc.
+- `ServerRequest::withoutAttribute` when attribute value is null.
+
+
+## [1.3.0] - 2016-04-13
+
+### Added
+
+- Remaining interfaces needed for full PSR7 compatibility
+  (ServerRequestInterface, UploadedFileInterface, etc.).
+- Support for stream_for from scalars.
+
+### Changed
+
+- Can now extend Uri.
+
+### Fixed
+- A bug in validating request methods by making it more permissive.
+
+
+## [1.2.3] - 2016-02-18
+
+### Fixed
+
+- Support in `GuzzleHttp\Psr7\CachingStream` for seeking forward on remote
+  streams, which can sometimes return fewer bytes than requested with `fread`.
+- Handling of gzipped responses with FNAME headers.
+
+
+## [1.2.2] - 2016-01-22
+
+### Added
+
+- Support for URIs without any authority.
+- Support for HTTP 451 'Unavailable For Legal Reasons.'
+- Support for using '0' as a filename.
+- Support for including non-standard ports in Host headers.
+
+
+## [1.2.1] - 2015-11-02
+
+### Changes
+
+- Now supporting negative offsets when seeking to SEEK_END.
+
+
+## [1.2.0] - 2015-08-15
+
+### Changed
+
+- Body as `"0"` is now properly added to a response.
+- Now allowing forward seeking in CachingStream.
+- Now properly parsing HTTP requests that contain proxy targets in
+  `parse_request`.
+- functions.php is now conditionally required.
+- user-info is no longer dropped when resolving URIs.
+
+
+## [1.1.0] - 2015-06-24
+
+### Changed
+
+- URIs can now be relative.
+- `multipart/form-data` headers are now overridden case-insensitively.
+- URI paths no longer encode the following characters because they are allowed
+  in URIs: "(", ")", "*", "!", "'"
+- A port is no longer added to a URI when the scheme is missing and no port is
+  present.
+
+
+## 1.0.0 - 2015-05-19
+
+Initial release.
+
+Currently unsupported:
+
+- `Psr\Http\Message\ServerRequestInterface`
+- `Psr\Http\Message\UploadedFileInterface`

+# PSR-7 Message Implementation
+
+This repository contains a full [PSR-7](http://www.php-fig.org/psr/psr-7/)
+message implementation, several stream decorators, and some helpful
+functionality like query string parsing.
+
+
+[![Build Status](https://travis-ci.org/guzzle/psr7.svg?branch=master)](https://travis-ci.org/guzzle/psr7)
+
+
+# Stream implementation
+
+This package comes with a number of stream implementations and stream
+decorators.
+
+
+## AppendStream
+
+`GuzzleHttp\Psr7\AppendStream`
+
+Reads from multiple streams, one after the other.
+
+```php
+use GuzzleHttp\Psr7;
+
+$a = Psr7\stream_for('abc, ');
+$b = Psr7\stream_for('123.');
+$composed = new Psr7\AppendStream([$a, $b]);
+
+$composed->addStream(Psr7\stream_for(' Above all listen to me'));
+
+echo $composed; // abc, 123. Above all listen to me.
+```
+
+
+## BufferStream
+
+`GuzzleHttp\Psr7\BufferStream`
+
+Provides a buffer stream that can be written to fill a buffer, and read
+from to remove bytes from the buffer.
+
+This stream returns a "hwm" metadata value that tells upstream consumers
+what the configured high water mark of the stream is, or the maximum
+preferred size of the buffer.
+
+```php
+use GuzzleHttp\Psr7;
+
+// When more than 1024 bytes are in the buffer, it will begin returning
+// false to writes. This is an indication that writers should slow down.
+$buffer = new Psr7\BufferStream(1024);
+```
+
+
+## CachingStream
+
+The CachingStream is used to allow seeking over previously read bytes on
+non-seekable streams. This can be useful when transferring a non-seekable
+entity body fails due to needing to rewind the stream (for example, resulting
+from a redirect). Data that is read from the remote stream will be buffered in
+a PHP temp stream so that previously read bytes are cached first in memory,
+then on disk.
+
+```php
+use GuzzleHttp\Psr7;
+
+$original = Psr7\stream_for(fopen('http://www.google.com', 'r'));
+$stream = new Psr7\CachingStream($original);
+
+$stream->read(1024);
+echo $stream->tell();
+// 1024
+
+$stream->seek(0);
+echo $stream->tell();
+// 0
+```
+
+
+## DroppingStream
+
+`GuzzleHttp\Psr7\DroppingStream`
+
+Stream decorator that begins dropping data once the size of the underlying
+stream becomes too full.
+
+```php
+use GuzzleHttp\Psr7;
+
+// Create an empty stream
+$stream = Psr7\stream_for();
+
+// Start dropping data when the stream has more than 10 bytes
+$dropping = new Psr7\DroppingStream($stream, 10);
+
+$dropping->write('01234567890123456789');
+echo $stream; // 0123456789
+```
+
+
+## FnStream
+
+`GuzzleHttp\Psr7\FnStream`
+
+Compose stream implementations based on a hash of functions.
+
+Allows for easy testing and extension of a provided stream without needing
+to create a concrete class for a simple extension point.
+
+```php
+
+use GuzzleHttp\Psr7;
+
+$stream = Psr7\stream_for('hi');
+$fnStream = Psr7\FnStream::decorate($stream, [
+    'rewind' => function () use ($stream) {
+        echo 'About to rewind - ';
+        $stream->rewind();
+        echo 'rewound!';
+    }
+]);
+
+$fnStream->rewind();
+// Outputs: About to rewind - rewound!
+```
+
+
+## InflateStream
+
+`GuzzleHttp\Psr7\InflateStream`
+
+Uses PHP's zlib.inflate filter to inflate deflate or gzipped content.
+
+This stream decorator skips the first 10 bytes of the given stream to remove
+the gzip header, converts the provided stream to a PHP stream resource,
+then appends the zlib.inflate filter. The stream is then converted back
+to a Guzzle stream resource to be used as a Guzzle stream.
+
+
+## LazyOpenStream
+
+`GuzzleHttp\Psr7\LazyOpenStream`
+
+Lazily reads or writes to a file that is opened only after an IO operation
+take place on the stream.
+
+```php
+use GuzzleHttp\Psr7;
+
+$stream = new Psr7\LazyOpenStream('/path/to/file', 'r');
+// The file has not yet been opened...
+
+echo $stream->read(10);
+// The file is opened and read from only when needed.
+```
+
+
+## LimitStream
+
+`GuzzleHttp\Psr7\LimitStream`
+
+LimitStream can be used to read a subset or slice of an existing stream object.
+This can be useful for breaking a large file into smaller pieces to be sent in
+chunks (e.g. Amazon S3's multipart upload API).
+
+```php
+use GuzzleHttp\Psr7;
+
+$original = Psr7\stream_for(fopen('/tmp/test.txt', 'r+'));
+echo $original->getSize();
+// >>> 1048576
+
+// Limit the size of the body to 1024 bytes and start reading from byte 2048
+$stream = new Psr7\LimitStream($original, 1024, 2048);
+echo $stream->getSize();
+// >>> 1024
+echo $stream->tell();
+// >>> 0
+```
+
+
+## MultipartStream
+
+`GuzzleHttp\Psr7\MultipartStream`
+
+Stream that when read returns bytes for a streaming multipart or
+multipart/form-data stream.
+
+
+## NoSeekStream
+
+`GuzzleHttp\Psr7\NoSeekStream`
+
+NoSeekStream wraps a stream and does not allow seeking.
+
+```php
+use GuzzleHttp\Psr7;
+
+$original = Psr7\stream_for('foo');
+$noSeek = new Psr7\NoSeekStream($original);
+
+echo $noSeek->read(3);
+// foo
+var_export($noSeek->isSeekable());
+// false
+$noSeek->seek(0);
+var_export($noSeek->read(3));
+// NULL
+```
+
+
+## PumpStream
+
+`GuzzleHttp\Psr7\PumpStream`
+
+Provides a read only stream that pumps data from a PHP callable.
+
+When invoking the provided callable, the PumpStream will pass the amount of
+data requested to read to the callable. The callable can choose to ignore
+this value and return fewer or more bytes than requested. Any extra data
+returned by the provided callable is buffered internally until drained using
+the read() function of the PumpStream. The provided callable MUST return
+false when there is no more data to read.
+
+
+## Implementing stream decorators
+
+Creating a stream decorator is very easy thanks to the
+`GuzzleHttp\Psr7\StreamDecoratorTrait`. This trait provides methods that
+implement `Psr\Http\Message\StreamInterface` by proxying to an underlying
+stream. Just `use` the `StreamDecoratorTrait` and implement your custom
+methods.
+
+For example, let's say we wanted to call a specific function each time the last
+byte is read from a stream. This could be implemented by overriding the
+`read()` method.
+
+```php
+use Psr\Http\Message\StreamInterface;
+use GuzzleHttp\Psr7\StreamDecoratorTrait;
+
+class EofCallbackStream implements StreamInterface
+{
+    use StreamDecoratorTrait;
+
+    private $callback;
+
+    public function __construct(StreamInterface $stream, callable $cb)
+    {
+        $this->stream = $stream;
+        $this->callback = $cb;
+    }
+
+    public function read($length)
+    {
+        $result = $this->stream->read($length);
+
+        // Invoke the callback when EOF is hit.
+        if ($this->eof()) {
+            call_user_func($this->callback);
+        }
+
+        return $result;
+    }
+}
+```
+
+This decorator could be added to any existing stream and used like so:
+
+```php
+use GuzzleHttp\Psr7;
+
+$original = Psr7\stream_for('foo');
+
+$eofStream = new EofCallbackStream($original, function () {
+    echo 'EOF!';
+});
+
+$eofStream->read(2);
+$eofStream->read(1);
+// echoes "EOF!"
+$eofStream->seek(0);
+$eofStream->read(3);
+// echoes "EOF!"
+```
+
+
+## PHP StreamWrapper
+
+You can use the `GuzzleHttp\Psr7\StreamWrapper` class if you need to use a
+PSR-7 stream as a PHP stream resource.
+
+Use the `GuzzleHttp\Psr7\StreamWrapper::getResource()` method to create a PHP
+stream from a PSR-7 stream.
+
+```php
+use GuzzleHttp\Psr7\StreamWrapper;
+
+$stream = GuzzleHttp\Psr7\stream_for('hello!');
+$resource = StreamWrapper::getResource($stream);
+echo fread($resource, 6); // outputs hello!
+```
+
+
+# Function API
+
+There are various functions available under the `GuzzleHttp\Psr7` namespace.
+
+
+## `function str`
+
+`function str(MessageInterface $message)`
+
+Returns the string representation of an HTTP message.
+
+```php
+$request = new GuzzleHttp\Psr7\Request('GET', 'http://example.com');
+echo GuzzleHttp\Psr7\str($request);
+```
+
+
+## `function uri_for`
+
+`function uri_for($uri)`
+
+This function accepts a string or `Psr\Http\Message\UriInterface` and returns a
+UriInterface for the given value. If the value is already a `UriInterface`, it
+is returned as-is.
+
+```php
+$uri = GuzzleHttp\Psr7\uri_for('http://example.com');
+assert($uri === GuzzleHttp\Psr7\uri_for($uri));
+```
+
+
+## `function stream_for`
+
+`function stream_for($resource = '', array $options = [])`
+
+Create a new stream based on the input type.
+
+Options is an associative array that can contain the following keys:
+
+* - metadata: Array of custom metadata.
+* - size: Size of the stream.
+
+This method accepts the following `$resource` types:
+
+- `Psr\Http\Message\StreamInterface`: Returns the value as-is.
+- `string`: Creates a stream object that uses the given string as the contents.
+- `resource`: Creates a stream object that wraps the given PHP stream resource.
+- `Iterator`: If the provided value implements `Iterator`, then a read-only
+  stream object will be created that wraps the given iterable. Each time the
+  stream is read from, data from the iterator will fill a buffer and will be
+  continuously called until the buffer is equal to the requested read size.
+  Subsequent read calls will first read from the buffer and then call `next`
+  on the underlying iterator until it is exhausted.
+- `object` with `__toString()`: If the object has the `__toString()` method,
+  the object will be cast to a string and then a stream will be returned that
+  uses the string value.
+- `NULL`: When `null` is passed, an empty stream object is returned.
+- `callable` When a callable is passed, a read-only stream object will be
+  created that invokes the given callable. The callable is invoked with the
+  number of suggested bytes to read. The callable can return any number of
+  bytes, but MUST return `false` when there is no more data to return. The
+  stream object that wraps the callable will invoke the callable until the
+  number of requested bytes are available. Any additional bytes will be
+  buffered and used in subsequent reads.
+
+```php
+$stream = GuzzleHttp\Psr7\stream_for('foo');
+$stream = GuzzleHttp\Psr7\stream_for(fopen('/path/to/file', 'r'));
+
+$generator = function ($bytes) {
+    for ($i = 0; $i < $bytes; $i++) {
+        yield ' ';
+    }
+}
+
+$stream = GuzzleHttp\Psr7\stream_for($generator(100));
+```
+
+
+## `function parse_header`
+
+`function parse_header($header)`
+
+Parse an array of header values containing ";" separated data into an array of
+associative arrays representing the header key value pair data of the header.
+When a parameter does not contain a value, but just contains a key, this
+function will inject a key with a '' string value.
+
+
+## `function normalize_header`
+
+`function normalize_header($header)`
+
+Converts an array of header values that may contain comma separated headers
+into an array of headers with no comma separated values.
+
+
+## `function modify_request`
+
+`function modify_request(RequestInterface $request, array $changes)`
+
+Clone and modify a request with the given changes. This method is useful for
+reducing the number of clones needed to mutate a message.
+
+The changes can be one of:
+
+- method: (string) Changes the HTTP method.
+- set_headers: (array) Sets the given headers.
+- remove_headers: (array) Remove the given headers.
+- body: (mixed) Sets the given body.
+- uri: (UriInterface) Set the URI.
+- query: (string) Set the query string value of the URI.
+- version: (string) Set the protocol version.
+
+
+## `function rewind_body`
+
+`function rewind_body(MessageInterface $message)`
+
+Attempts to rewind a message body and throws an exception on failure. The body
+of the message will only be rewound if a call to `tell()` returns a value other
+than `0`.
+
+
+## `function try_fopen`
+
+`function try_fopen($filename, $mode)`
+
+Safely opens a PHP stream resource using a filename.
+
+When fopen fails, PHP normally raises a warning. This function adds an error
+handler that checks for errors and throws an exception instead.
+
+
+## `function copy_to_string`
+
+`function copy_to_string(StreamInterface $stream, $maxLen = -1)`
+
+Copy the contents of a stream into a string until the given number of bytes
+have been read.
+
+
+## `function copy_to_stream`
+
+`function copy_to_stream(StreamInterface $source, StreamInterface $dest, $maxLen = -1)`
+
+Copy the contents of a stream into another stream until the given number of
+bytes have been read.
+
+
+## `function hash`
+
+`function hash(StreamInterface $stream, $algo, $rawOutput = false)`
+
+Calculate a hash of a Stream. This method reads the entire stream to calculate
+a rolling hash (based on PHP's hash_init functions).
+
+
+## `function readline`
+
+`function readline(StreamInterface $stream, $maxLength = null)`
+
+Read a line from the stream up to the maximum allowed buffer length.
+

+
+`function parse_request($message)`
+
+Parses a request message string into a request object.
+
+
+## `function parse_response`
+
+`function parse_response($message)`
+
+Parses a response message string into a response object.
+
+
+## `function parse_query`
+
+`function parse_query($str, $urlEncoding = true)`
+
+Parse a query string into an associative array.
+
+If multiple values are found for the same key, the value of that key value pair
+will become an array. This function does not parse nested PHP style arrays into
+an associative array (e.g., `foo[a]=1&foo[b]=2` will be parsed into
+`['foo[a]' => '1', 'foo[b]' => '2']`).
+

+This function does not modify the provided keys when an array is encountered
+(like http_build_query would).
+
+
+## `function mimetype_from_filename`
+
+`function mimetype_from_filename($filename)`
+
+Determines the mimetype of a file by looking at its extension.

+
+# Additional URI Methods
+
+Aside from the standard `Psr\Http\Message\UriInterface` implementation in form of the `GuzzleHttp\Psr7\Uri` class,
+this library also provides additional functionality when working with URIs as static methods.
+
+## URI Types
+
+An instance of `Psr\Http\Message\UriInterface` can either be an absolute URI or a relative reference.
+An absolute URI has a scheme. A relative reference is used to express a URI relative to another URI,
+the base URI. Relative references can be divided into several forms according to
+[RFC 3986 Section 4.2](https://tools.ietf.org/html/rfc3986#section-4.2):
+
+- network-path references, e.g. `//example.com/path`
+- absolute-path references, e.g. `/path`
+- relative-path references, e.g. `subpath`
+
+The following methods can be used to identify the type of the URI.
+
+### `GuzzleHttp\Psr7\Uri::isAbsolute`
+
+`public static function isAbsolute(UriInterface $uri): bool`
+
+Whether the URI is absolute, i.e. it has a scheme.
+
+### `GuzzleHttp\Psr7\Uri::isNetworkPathReference`
+
+`public static function isNetworkPathReference(UriInterface $uri): bool`
+
+Whether the URI is a network-path reference. A relative reference that begins with two slash characters is
+termed an network-path reference.
+
+### `GuzzleHttp\Psr7\Uri::isAbsolutePathReference`
+
+`public static function isAbsolutePathReference(UriInterface $uri): bool`
+
+Whether the URI is a absolute-path reference. A relative reference that begins with a single slash character is
+termed an absolute-path reference.
+
+### `GuzzleHttp\Psr7\Uri::isRelativePathReference`
+
+`public static function isRelativePathReference(UriInterface $uri): bool`
+
+Whether the URI is a relative-path reference. A relative reference that does not begin with a slash character is
+termed a relative-path reference.
+
+### `GuzzleHttp\Psr7\Uri::isSameDocumentReference`
+
+`public static function isSameDocumentReference(UriInterface $uri, UriInterface $base = null): bool`
+
+Whether the URI is a same-document reference. A same-document reference refers to a URI that is, aside from its
+fragment component, identical to the base URI. When no base URI is given, only an empty URI reference
+(apart from its fragment) is considered a same-document reference.
+
+## URI Components
+
+Additional methods to work with URI components.
+
+### `GuzzleHttp\Psr7\Uri::isDefaultPort`
+
+`public static function isDefaultPort(UriInterface $uri): bool`
+
+Whether the URI has the default port of the current scheme. `Psr\Http\Message\UriInterface::getPort` may return null
+or the standard port. This method can be used independently of the implementation.
+
+### `GuzzleHttp\Psr7\Uri::composeComponents`
+
+`public static function composeComponents($scheme, $authority, $path, $query, $fragment): string`
+
+Composes a URI reference string from its various components according to
+[RFC 3986 Section 5.3](https://tools.ietf.org/html/rfc3986#section-5.3). Usually this method does not need to be called
+manually but instead is used indirectly via `Psr\Http\Message\UriInterface::__toString`.
+
+### `GuzzleHttp\Psr7\Uri::fromParts`
+
+`public static function fromParts(array $parts): UriInterface`
+
+Creates a URI from a hash of [`parse_url`](http://php.net/manual/en/function.parse-url.php) components.
+
+
+### `GuzzleHttp\Psr7\Uri::withQueryValue`
+
+`public static function withQueryValue(UriInterface $uri, $key, $value): UriInterface`
+
+Creates a new URI with a specific query string value. Any existing query string values that exactly match the
+provided key are removed and replaced with the given key value pair. A value of null will set the query string
+key without a value, e.g. "key" instead of "key=value".
+
+### `GuzzleHttp\Psr7\Uri::withQueryValues`
+
+`public static function withQueryValues(UriInterface $uri, array $keyValueArray): UriInterface`
+
+Creates a new URI with multiple query string values. It has the same behavior as `withQueryValue()` but for an
+associative array of key => value.
+
+### `GuzzleHttp\Psr7\Uri::withoutQueryValue`
+
+`public static function withoutQueryValue(UriInterface $uri, $key): UriInterface`
+
+Creates a new URI with a specific query string value removed. Any existing query string values that exactly match the
+provided key are removed.
+
+## Reference Resolution
+
+`GuzzleHttp\Psr7\UriResolver` provides methods to resolve a URI reference in the context of a base URI according
+to [RFC 3986 Section 5](https://tools.ietf.org/html/rfc3986#section-5). This is for example also what web browsers
+do when resolving a link in a website based on the current request URI.
+
+### `GuzzleHttp\Psr7\UriResolver::resolve`
+
+`public static function resolve(UriInterface $base, UriInterface $rel): UriInterface`
+
+Converts the relative URI into a new URI that is resolved against the base URI.
+
+### `GuzzleHttp\Psr7\UriResolver::removeDotSegments`
+
+`public static function removeDotSegments(string $path): string`
+
+Removes dot segments from a path and returns the new path according to
+[RFC 3986 Section 5.2.4](https://tools.ietf.org/html/rfc3986#section-5.2.4).
+
+### `GuzzleHttp\Psr7\UriResolver::relativize`
+
+`public static function relativize(UriInterface $base, UriInterface $target): UriInterface`
+
+Returns the target URI as a relative reference from the base URI. This method is the counterpart to resolve():
+
+```php
+(string) $target === (string) UriResolver::resolve($base, UriResolver::relativize($base, $target))
+```
+
+One use-case is to use the current request URI as base URI and then generate relative links in your documents
+to reduce the document size or offer self-contained downloadable document archives.
+
+```php
+$base = new Uri('http://example.com/a/b/');
+echo UriResolver::relativize($base, new Uri('http://example.com/a/b/c'));  // prints 'c'.
+echo UriResolver::relativize($base, new Uri('http://example.com/a/x/y'));  // prints '../x/y'.
+echo UriResolver::relativize($base, new Uri('http://example.com/a/b/?q')); // prints '?q'.
+echo UriResolver::relativize($base, new Uri('http://example.org/a/b/'));   // prints '//example.org/a/b/'.
+```
+
+## Normalization and Comparison
+
+`GuzzleHttp\Psr7\UriNormalizer` provides methods to normalize and compare URIs according to
+[RFC 3986 Section 6](https://tools.ietf.org/html/rfc3986#section-6).
+
+### `GuzzleHttp\Psr7\UriNormalizer::normalize`
+
+`public static function normalize(UriInterface $uri, $flags = self::PRESERVING_NORMALIZATIONS): UriInterface`
+
+Returns a normalized URI. The scheme and host component are already normalized to lowercase per PSR-7 UriInterface.
+This methods adds additional normalizations that can be configured with the `$flags` parameter which is a bitmask
+of normalizations to apply. The following normalizations are available:
+
+- `UriNormalizer::PRESERVING_NORMALIZATIONS`
+
+    Default normalizations which only include the ones that preserve semantics.
+
+- `UriNormalizer::CAPITALIZE_PERCENT_ENCODING`
+
+    All letters within a percent-encoding triplet (e.g., "%3A") are case-insensitive, and should be capitalized.
+
+    Example: `http://example.org/a%c2%b1b` → `http://example.org/a%C2%B1b`
+
+- `UriNormalizer::DECODE_UNRESERVED_CHARACTERS`
+
+    Decodes percent-encoded octets of unreserved characters. For consistency, percent-encoded octets in the ranges of
+    ALPHA (%41–%5A and %61–%7A), DIGIT (%30–%39), hyphen (%2D), period (%2E), underscore (%5F), or tilde (%7E) should
+    not be created by URI producers and, when found in a URI, should be decoded to their corresponding unreserved
+    characters by URI normalizers.
+
+    Example: `http://example.org/%7Eusern%61me/` → `http://example.org/~username/`
+
+- `UriNormalizer::CONVERT_EMPTY_PATH`
+
+    Converts the empty path to "/" for http and https URIs.
+
+    Example: `http://example.org` → `http://example.org/`
+
+- `UriNormalizer::REMOVE_DEFAULT_HOST`
+
+    Removes the default host of the given URI scheme from the URI. Only the "file" scheme defines the default host
+    "localhost". All of `file:/myfile`, `file:///myfile`, and `file://localhost/myfile` are equivalent according to
+    RFC 3986.
+
+    Example: `file://localhost/myfile` → `file:///myfile`
+
+- `UriNormalizer::REMOVE_DEFAULT_PORT`
+
+    Removes the default port of the given URI scheme from the URI.
+
+    Example: `http://example.org:80/` → `http://example.org/`
+
+- `UriNormalizer::REMOVE_DOT_SEGMENTS`
+
+    Removes unnecessary dot-segments. Dot-segments in relative-path references are not removed as it would
+    change the semantics of the URI reference.
+
+    Example: `http://example.org/../a/b/../c/./d.html` → `http://example.org/a/c/d.html`
+
+- `UriNormalizer::REMOVE_DUPLICATE_SLASHES`
+
+    Paths which include two or more adjacent slashes are converted to one. Webservers usually ignore duplicate slashes
+    and treat those URIs equivalent. But in theory those URIs do not need to be equivalent. So this normalization
+    may change the semantics. Encoded slashes (%2F) are not removed.
+
+    Example: `http://example.org//foo///bar.html` → `http://example.org/foo/bar.html`
+
+- `UriNormalizer::SORT_QUERY_PARAMETERS`
+
+    Sort query parameters with their values in alphabetical order. However, the order of parameters in a URI may be
+    significant (this is not defined by the standard). So this normalization is not safe and may change the semantics
+    of the URI.
+
+    Example: `?lang=en&article=fred` → `?article=fred&lang=en`
+
+### `GuzzleHttp\Psr7\UriNormalizer::isEquivalent`
+
+`public static function isEquivalent(UriInterface $uri1, UriInterface $uri2, $normalizations = self::PRESERVING_NORMALIZATIONS): bool`
+
+Whether two URIs can be considered equivalent. Both URIs are normalized automatically before comparison with the given
+`$normalizations` bitmask. The method also accepts relative URI references and returns true when they are equivalent.
+This of course assumes they will be resolved against the same base URI. If this is not the case, determination of
+equivalence or difference of relative references does not mean anything.

+# LazyJsonMapper
+
+## Advanced, intelligent & automatic object-oriented JSON containers for PHP.
+
+Implements a highly efficient, automatic, object-oriented and lightweight
+(memory-wise) JSON data container. It provides intelligent data conversion
+and parsing, to give you a nice, reliable interface to your JSON data,
+without having to worry about doing any of the tedious parsing yourself.
+
+### Features:
+
+- Provides a completely object-oriented interface to all of your JSON data.
+
+- Automatically maps complex, nested JSON data structures onto real PHP
+  objects, with total support for nested objects and multi-level arrays.
+
+- Extremely optimized for very high performance and very low memory usage.
+  Much lower than other PHP JSON mappers that people have used in the past.
+
+  For example, normal PHP objects with manually defined `$properties`, which
+  is what's used by _other_ JSON mappers, will consume memory for every
+  property even if that property wasn't in the JSON data (is a `NULL`). Our
+  system on the other hand takes up ZERO bytes of RAM for any properties
+  that don't exist in the current object's JSON data!
+
+- Automatically provides "direct virtual properties", which lets you
+  interact with the JSON data as if it were regular object properties,
+  such as `echo $item->some_value` and `$item->some_value = 'foo'`.
+
+  The virtual properties can be disabled via an option.
+
+- Automatically provides object-oriented "virtual functions", which let you
+  interact with the data in a fully object-oriented way via functions such
+  as `$item->getSomeValue()` and `$item->setSomeValue('foo')`. We support a
+  large range of different functions for manipulating the JSON data, and you
+  can see a list of all available function names for all of your properties
+  by simply running `$item->printPropertyDescriptions()`.
+
+  The virtual functions can be disabled via an option.
+
+- Includes the `LazyDoctor` tool, which _automatically_ documents all of
+  your `LazyJsonMapper`-based classes so that their virtual properties and
+  functions become _fully_ visible to your IDE and to various intelligent
+  code analysis tools. It also performs class diagnostics by compiling all
+  of your class property maps, which means that you can be 100% sure that
+  all of your maps are valid (compilable) if this tool runs successfully.
+
+- We provide a complete, internal API which your subclasses can use to
+  interact with the data inside of the JSON container. This allows you to
+  easily override the automatic functions or create additional functions
+  for your objects. To override core functions, just define a function with
+  the exact same name on your object and make it do whatever you want to.
+
+  Here are some examples of function overriding:
+
+    ```php
+    public function getFoo()
+    {
+        // try to read property, and handle a special "current_time" value.
+        $value = $this->_getProperty('foo');
+        if ($value === 'current_time') { return time(); }
+        return $value;
+    }
+    public function setFoo(
+        $value)
+    {
+        // if they try to set value to "md5", we use a special value instead
+        if ($value === 'md5') { $value = md5(time()); }
+        return $this->_setProperty('foo', $value);
+    }
+    ```
+
+- All mapping/data conversion is done "lazily", on a per-property basis.
+  When you access a property, that specific property is mapped/converted to
+  the proper type as defined by your class property map. No time or memory
+  is wasted converting properties that you never touch.
+
+- Strong type-system. The class property map controls the exact types and
+  array depths. You can fully trust that the data you get/set will match
+  your specifications. Invalid data that mismatches the spec is impossible.
+
+- Advanced settings system. Everything is easily configured via PHP class
+  constants, which means that your class-settings are stateless (there's no
+  need for any special "settings/mapper object" to keep track of settings),
+  and that all settings are immutable constants (which means that they are
+  reliable and can never mutate at runtime, so that you can fully trust that
+  classes will always behave as-defined in their code).
+
+  If you want to override multiple core settings identically for all of your
+  classes, then simply create a subclass of `LazyJsonMapper` and configure
+  all of your settings on that, and then derive all of your other classes
+  from your re-configured subclass!
+
+- The world's most advanced mapper definition system. Your class property
+  maps are defined in an easy PHPdoc-style format, and support multilevel
+  arrays (such as `int[][]` for "an array of arrays of ints"), relative
+  types (so you can map properties to classes/objects that are relative to
+  the namespace of the class property map), parent inheritance (all of your
+  parent `extends`-hierarchy's maps will be included in your final property
+  map) and even multiple inheritance (you can literally "import" an infinite
+  number of other maps into your class, which don't come from your own
+  parent `extends`-hierarchy).
+
+- Inheriting properties from parent classes or importing properties from
+  other classes is a zero-cost operation thanks to how efficient our
+  property map compiler is. So feel free to import everything you need.
+  You can even use this system to create importable classes that just hold
+  "collections" of shared properties, which you import into other classes.
+
+- The class property maps are compiled a single time per-class at runtime,
+  the first time a class is used. The compilation process fully verifies
+  and compiles all property definitions, all parent maps, all inherited
+  maps, and all maps of all classes you link properties to.
+
+  If there are any compilation problems due to a badly written map anywhere
+  in your hierarchy, you will be shown the exact problem in great detail.
+
+  In case of success, the compiled and verified maps are all stored in an
+  incredibly memory-efficient format in a global cache which is shared by
+  your whole PHP runtime, which means that anything in your code or in any
+  other libraries which accesses the same classes will all share the cached
+  compilations of those classes, for maximum memory efficiency.
+
+- You are also able to access JSON properties that haven't been defined in
+  the class property map. In that case, they are treated as undefined and
+  untyped (`mixed`) and there won't be any automatic type-conversion of such
+  properties, but it can still be handy in a pinch.
+
+- There are lots of data export/output options for your object's JSON data,
+  to get it back out of the object again: As a multi-level array, as nested
+  stdClass objects, or as a JSON string representation of your object.
+
+- We include a whole assortment of incredibly advanced debugging features:
+
+  You can run the constructor with `$requireAnalysis` to ensure that all
+  of your JSON data is successfully mapped according to your class property
+  map, and that you haven't missed defining any properties that exist in the
+  data. In case of any problems, the analysis message will give you a full
+  list of all problems encountered in your entire JSON data hierarchy.
+
+  For your class property maps themselves, you can run functions such as
+  `printPropertyDescriptions()` to see a complete list of all properties and
+  how they are defined. This helps debug your class inheritance and imports
+  to visually see what your final class map looks like, and it also helps
+  users see all available properties and all of their virtual functions.
+
+  And for the JSON data, you can use functions such as `printJson()` to get
+  a beautiful view of all internal JSON data, which is incredibly helpful
+  when you (or your users) need to figure out what's available inside the
+  current object instance's data storage.
+
+- A fine-grained and logical exception-system which ensures that you can
+  always trust the behavior of your objects and can catch problems easily.
+  And everything we throw is _always_ based on `LazyJsonMapperException`,
+  which means that you can simply catch that single "root" exception
+  whenever you don't care about fine-grained differentiation.
+
+- Clean and modular code ensures stability and future extensibility.
+
+- Deep code documentation explains everything you could ever wonder about.
+
+- Lastly, we implement super-efficient object serialization. Everything is
+  stored in a tightly packed format which minimizes data size when you need
+  to transfer your objects between runtimes.
+
+### Installation
+
+You need at least PHP 5.6 or higher. PHP 7+ is also fully supported and is recommended.
+
+Run the following [Composer](https://getcomposer.org/download/) installation command:
+
+```
+composer require lazyjsonmapper/lazyjsonmapper
+```
+
+### Examples
+
+View the contents of the [`examples/`](https://github.com/SteveJobzniak/LazyJsonMapper/tree/master/examples) folder.
+
+### Documentation
+
+Everything is fully documented directly within the source code of this library.
+
+You can also [read the same documentation online](https://mgp25.github.io/lazyjsonmapper-docs/namespaces/LazyJsonMapper.html) as nicely formatted HTML pages.
+
+### LazyDoctor
+
+Our automatic class-documentation and diagnostic utility will be placed within
+your project's `./vendor/bin/` folder. Simply run it without any parameters to
+see a list of all available options. You can also open that file in a regular
+text editor to read some general usage tips and tricks at the top of the
+utility's source code.

+/*
+ * The Lazy Doctor.
+ *
+ * This tool automatically builds up-to-date class documentation for all classes
+ * that derive from LazyJsonMapper, and documents their virtual properties and
+ * functions by adding "@property" and "@method" declarations to their class
+ * PHPdoc blocks. That documentation is necessary for things like code analysis
+ * tools and IDE autocomplete for all of your virtual properties/functions!
+ *
+ * LazyDoctor also performs class diagnostics: It compiles the class property
+ * maps of _all_ of your LazyJsonMapper-based classes, which means that you can
+ * be 100% sure that all of your maps are valid if this tool runs successfully.
+ *
+ * To see all available options, type "./vendor/bin/lazydoctor --help".
+ *
+ * To begin, simply point the "--composer" option at the "composer.json" file
+ * for your project. Just be aware that your project MUST be based on PSR-4
+ * autoloading, with ONE OR MORE defined autoload-namespaces in "composer.json".
+ *
+ * You can read more about PSR-4 autoloading at the official Composer site:
+ *
+ * https://getcomposer.org/doc/04-schema.md#autoload
+ *
+ * This tool will ONLY parse classes that properly follow PSR-4 autoloading!
+ *
+ * In addition to the composer-file, you'll also have to specify whether you
+ * want to document virtual "--properties", virtual "--functions", or BOTH.
+ * Note that we'll ONLY document them when the individual classes support that
+ * kind of access (when it hasn't disabled its class-option for that feature).
+ *
+ * If you don't provide any documentation flags, we'll instead REMOVE all of
+ * the current class "virtual @property/@method" documentation. That can be
+ * useful for restoring your files if you don't want to document them anymore.
+ *
+ * You should also be aware of "--document-overridden", which will document
+ * virtual properties or functions even if they're already manually defined
+ * (overridden) by the class or its parents. That can be useful if you want to
+ * ensure that you ALWAYS document the virtual properties/functions in all of
+ * your class files even when it has been overridden somewhere. In that case,
+ * you should ensure that your overridden properties/functions have the SAME or
+ * a COMPATIBLE signature & return value, so their auto-docs are still correct.
+ *
+ * Tip: You can use the "--validate-only" param to check docs without writing to
+ * disk. That can be useful when making a non-destructive Git "pre-commit hook"
+ * to validate your repo and ensure that all files have updated documentation!
+ *
+ * This script always uses exit codes to indicate success. A non-zero exit code
+ * indicates that some files needed new class docs (in "--validate-only" mode),
+ * or that there was a general problem while processing.
+ *
+ * Lastly, you may appreciate the ability to silence all unimportant status
+ * messages! To do so, simply use ">/dev/null" to send STDOUT to the void...
+ * That way you'll ONLY see critical status messages during the processing.

+// tests during development of LazyJsonMapper... I barely even cared about
+// grammar since this file was just meant to dump a bunch of tests in and not
+// meant for public use. But it has so many extremely important tests that
+// cover all kinds of common and unusual scenarios. Several of the tests may
+// be outdated and test details that later changed during development. So
+// everything below needs to be carefully revised.
+//
+// We REALLY SHOULD rewrite everything as clean and organized PHPUnit tests...
+// if SOMEONE has the energy...
+//
+// PS: If anyone is using this library for commercial purposes, then a nice way
+// to contribute back as a "thank you!" would be to manually go through
+// everything below and rewrite relevant tests as beautiful PHPunit tests. :-)
+// If someone wants to contribute, you can do the test-rewrite step by step and
+// won't have to do everything all at once. ;-)

+/*
+ * I created these stack-based array loop algorithms for fun, just to try out
+ * an idea I had in mind. They are algorithms for iterating through multi-level
+ * arrays without needing any recursive function calls. And they are fully
+ * capable of tracking the current array-depth that they're operating at...
+ *
+ * These are the algorithms I tested:
+ * - RecursiveIteratorIterator = PHP's built-in object-based iterator library
+ * - array_flat_topdown_traverse = my stack-based algorithm v1
+ * - array_flat_topdown_traverse2 = my stack-based algorithm v2 (optimized)
+ * - array_recursive_traverse = simple recursive function calls
+ *
+ * The recursive function calls add 1 extra level to the call-stack for every
+ * deeper array depth-level that it enters.
+ *
+ * Therefore, I tested everything with test-data that contained array-depth 6
+ * (that's usually max in normal JSON data), 50 (rare), 500 (insane) and finally
+ * 5000 (hellish). The latter means that the recursive function calls-stack will
+ * reach a depth of 5000 recursive calls inside of each other. Hell indeed.
+ *
+ * The algorithms were a success; MASSIVELY beating `RecursiveIteratorIterator`
+ * from PHP's standard library by a factor of being almost 10x faster than it.
+ *
+ * Here's the fun thing, though: Simple, old-school recursive function-calls
+ * beats even my algorithm by a factor of being 2x faster!
+ *
+ * As for memory usage? The 500-levels deep recursive function calls didn't even
+ * make a noticeable blip on the radar...! They don't cause any stack memory
+ * overflows. On PHP5, this WHOLE test-script used 7.4 MB at peak while running
+ * all of the various tests. On PHP7, it used 4.7 MB at peak. And that's for the
+ * whole PHP binary, its runtime, etc! I didn't test the 5000-levels deep, but
+ * we'll never have such insane JSON data. So there's absolutely ZERO reason to
+ * worry about memory-usage of the recursive array resolver in LazyJsonMapper.
+ * Especially since normal JSON maps usually have 1-2 levels of array-depth. Now
+ * we know that we'll easily handle 500 levels or more. So no need to worry!
+ *
+ * Therefore there's no need to implement any kind of non-recursive resolver for
+ * array processing in this library! Recursive function calls are by far the
+ * fastest way to traverse the whole data array.
+ *
+ * I'll keep this test-file just in case anyone ever complains about the
+ * decision to use recursive function calls for the multi-level array
+ * processing in LazyJsonMapper.

+// into "get" and "SomethingSomething".
+//
+// This kind of micro-optimization is kind of overkill. But so is
+// everything else about the LazyJsonMapper project! ;-) And I was
+// curious about the performance implications of each method!
+//
+// NOTE about algorithm speed:
+// In all of these test algorithms I do a "get" check LAST, to
+// force PHP to check less common prefixes first, to ensure
+// that it fairly represents normal usage (since the test-data
+// overrepresents its amount of "get" functions and would therefore
+// usually short-circuit each test very quickly). in a real
+// algorithm, get should be first, since it's the most common prefix.

+// preg_split algorithm:
+// very fast. splits on the first non-lowercase ("not a-z") character.
+// never any false positives! the prefix-split is truly perfect,
+// so "getgetgetSomething" would split as "getgetget" and "Something".
+// this is basically like the preg_match, except that we do the split
+// and THEN use regular string comparison to check if the prefix
+// is a valid one. this has the benefit of allowing us to add lots
+// of other prefixes over time, without slowing down a preg_match
+// regex even more (since that one has to slowly look for EACH possible
+// prefix string repeatedly and requires far more regex engine steps).
+//
+// NOTE: in both PHP5 and PHP7, the preg_split method is almost exactly
+// 5x slower than isset(), but we're talking about microsecond level!
+// a microsecond is a MILLIONTH of a second. so I'm going to choose
+// the preg_split method. it saves tons of RAM compared to caching
+// EVERY individual exact function name via isset(). the only really
+// heavy part is the FuncCase-to-property_name translation from the
+// SomethingSomething part of "getSomethingSomething". so THAT is the
+// only part we really need to cache. This initial prefix-splitting
+// is better handled live on every function call to save RAM.
+//
+// benchmarks:
+// PHP7:
+// preg_split per item: 0.5883 Microseconds (0.0000005883 seconds)
+// isset() per item: 0.1053 Microseconds (0.0000001053 seconds)
+// PHP5:
+// preg_split per item: 2.3158 Microseconds (0.0000023158 seconds)
+// isset() per item: 0.4752 Microseconds (0.000004752 seconds)
+//
+// so for a ~5x increase in operation time at a microsecond-level,
+// we get MUCH LOWER RAM USAGE by only having to cache the shared
+// "SomethingSomething" part, rather than "getSomethingSomething",
+// "setSomethingSomething", "isSomethingSomething", "hasSomethingSomething"
+// and "unsetSomethingSomething".
+//
+// for someone using tens of thousands of calls, the prefix splitting
+// will be impressively instant. just try this file with $iterations = 1!
+// in that case, all of the prefix-splittings for 10,000 function
+// calls run in a COMBINED total of ~3.4 milliseconds! for ALL of them!
+// even in PHP5 it's around ~11 milliseconds for 10,000 prefix-splits.
+//
+// even if someone has millions of magic function calls, they won't
+// notice this preg_split() processing in relation to all of their
+// other processing when they have that many calls! that's how fast
+// the splitting is. and it saves 5x RAM at the moment (and even more
+// if more function prefix variations are added later).

+ * multiple great methods for working with objects that have unpredictable keys!
+ *
+ * There are other methods too, such as if your class contains a blend of known
+ * (defined) keys and unpredictable keys, in which case you'd need to fetch via
+ * `asArray()` as in the `UnpredictableContainer` example, and then you'd simply
+ * filter out all known keys from your cache, to get _just_ the unpredictable
+ * keys. And if you need setters in that scenario, your setter functions would
+ * be a bit more complex since they would need to use `assignObjectData()` AND
+ * would have to provide BOTH the known data AND the unknown data. One way of
+ * doing that would be to use `_getProperty()` to merge in the CURRENT values of
+ * each core property into your NEW object-data array BEFORE you assign it. But
+ * I leave that extremely rare scenario as an excercise for you, dear reader!
+ *
+ * You should go out and adapt all of this code to fit your own needs! ;-)
+ *
+ * For example, if you don't need the unpredictable values to be converted
+ * to/from a specific object type, then simply skip the conversion code.
+ *
+ * If you don't need caching for performance, then skip the caching code.
+ *
+ * If you don't need setters/syncing, then skip all of that code.
+ *
+ * You may also want to disable the user-options `ALLOW_VIRTUAL_PROPERTIES` and
+ * `ALLOW_VIRTUAL_FUNCTIONS` on your unpredictable containers, so users cannot
+ * manipulate the unpredictable data via LazyJsonMapper's automatic functions!
+ * That's what we did for CoreUnpredictableContainer, to ensure that nobody can
+ * destroy its internal data by touching it directly. They can only manipulate
+ * the data via its safe, public `getData()` and `setData()` functions!
+ *
+ * And you may perhaps prefer to write a custom base-class which has a few other
+ * helper-functions for doing these kinds of data translations, caching and
+ * syncing, to make your own work easier (such as the CoreUnpredictableContainer
+ * example above). That way, your various sub-classes could just call your
+ * internal helper functions to do the required processing automatically! :-)

+ * The possibilities are endless! Have fun!

+/**
+ * Advanced, intelligent & automatic object-oriented JSON containers for PHP.
+ *
+ * Implements a highly efficient, automatic, object-oriented and lightweight
+ * (memory-wise) JSON data container. It provides intelligent data conversion
+ * and parsing, to give you a nice, reliable interface to your JSON data,
+ * without having to worry about doing any of the tedious parsing yourself.
+ *
+ * Features:
+ *
+ *  - Provides a completely object-oriented interface to all of your JSON data.
+ *
+ *  - Automatically maps complex, nested JSON data structures onto real PHP
+ *    objects, with total support for nested objects and multi-level arrays.
+ *
+ *  - Extremely optimized for very high performance and very low memory usage.
+ *    Much lower than other PHP JSON mappers that people have used in the past.
+ *
+ *    For example, normal PHP objects with manually defined `$properties`, which
+ *    is what's used by _other_ JSON mappers, will consume memory for every
+ *    property even if that property wasn't in the JSON data (is a `NULL`). Our
+ *    system on the other hand takes up ZERO bytes of RAM for any properties
+ *    that don't exist in the current object's JSON data!
+ *
+ *  - Automatically provides "direct virtual properties", which lets you
+ *    interact with the JSON data as if it were regular object properties,
+ *    such as `echo $item->some_value` and `$item->some_value = 'foo'`.
+ *
+ *    The virtual properties can be disabled via an option.
+ *
+ *  - Automatically provides object-oriented "virtual functions", which let you
+ *    interact with the data in a fully object-oriented way via functions such
+ *    as `$item->getSomeValue()` and `$item->setSomeValue('foo')`. We support a
+ *    large range of different functions for manipulating the JSON data, and you
+ *    can see a list of all available function names for all of your properties
+ *    by simply running `$item->printPropertyDescriptions()`.
+ *
+ *    The virtual functions can be disabled via an option.
+ *
+ *  - Includes the `LazyDoctor` tool, which _automatically_ documents all of
+ *    your `LazyJsonMapper`-based classes so that their virtual properties and
+ *    functions become _fully_ visible to your IDE and to various intelligent
+ *    code analysis tools. It also performs class diagnostics by compiling all
+ *    of your class property maps, which means that you can be 100% sure that
+ *    all of your maps are valid (compilable) if this tool runs successfully.
+ *
+ *  - We provide a complete, internal API which your subclasses can use to
+ *    interact with the data inside of the JSON container. This allows you to
+ *    easily override the automatic functions or create additional functions
+ *    for your objects. To override core functions, just define a function with
+ *    the exact same name on your object and make it do whatever you want to.
+ *
+ *    Here are some examples of function overriding:
+ *
+ *      ```php
+ *      public function getFoo()
+ *      {
+ *          // try to read property, and handle a special "current_time" value.
+ *          $value = $this->_getProperty('foo');
+ *          if ($value === 'current_time') { return time(); }
+ *          return $value;
+ *      }
+ *      public function setFoo(
+ *          $value)
+ *      {
+ *          // if they try to set value to "md5", use a special value instead.
+ *          if ($value === 'md5') { $value = md5(time()); }
+ *          return $this->_setProperty('foo', $value);
+ *      }
+ *      ```
+ *
+ *  - All mapping/data conversion is done "lazily", on a per-property basis.
+ *    When you access a property, that specific property is mapped/converted to
+ *    the proper type as defined by your class property map. No time or memory
+ *    is wasted converting properties that you never touch.
+ *
+ *  - Strong type-system. The class property map controls the exact types and
+ *    array depths. You can fully trust that the data you get/set will match
+ *    your specifications. Invalid data that mismatches the spec is impossible.
+ *
+ *  - Advanced settings system. Everything is easily configured via PHP class
+ *    constants, which means that your class-settings are stateless (there's no
+ *    need for any special "settings/mapper object" to keep track of settings),
+ *    and that all settings are immutable constants (which means that they are
+ *    reliable and can never mutate at runtime, so that you can fully trust that
+ *    classes will always behave as-defined in their code).
+ *
+ *    If you want to override multiple core settings identically for all of your
+ *    classes, then simply create a subclass of `LazyJsonMapper` and configure
+ *    all of your settings on that, and then derive all of your other classes
+ *    from your re-configured subclass!
+ *
+ *  - The world's most advanced mapper definition system. Your class property
+ *    maps are defined in an easy PHPdoc-style format, and support multilevel
+ *    arrays (such as `int[][]` for "an array of arrays of ints"), relative
+ *    types (so you can map properties to classes/objects that are relative to
+ *    the namespace of the class property map), parent inheritance (all of your
+ *    parent `extends`-hierarchy's maps will be included in your final property
+ *    map) and even multiple inheritance (you can literally "import" an infinite
+ *    number of other maps into your class, which don't come from your own
+ *    parent `extends`-hierarchy).
+ *
+ *  - Inheriting properties from parent classes or importing properties from
+ *    other classes is a zero-cost operation thanks to how efficient our
+ *    property map compiler is. So feel free to import everything you need.
+ *    You can even use this system to create importable classes that just hold
+ *    "collections" of shared properties, which you import into other classes.
+ *
+ *  - The class property maps are compiled a single time per-class at runtime,
+ *    the first time a class is used. The compilation process fully verifies
+ *    and compiles all property definitions, all parent maps, all inherited
+ *    maps, and all maps of all classes you link properties to.
+ *
+ *    If there are any compilation problems due to a badly written map anywhere
+ *    in your hierarchy, you will be shown the exact problem in great detail.
+ *
+ *    In case of success, the compiled and verified maps are all stored in an
+ *    incredibly memory-efficient format in a global cache which is shared by
+ *    your whole PHP runtime, which means that anything in your code or in any
+ *    other libraries which accesses the same classes will all share the cached
+ *    compilations of those classes, for maximum memory efficiency.
+ *
+ *  - You are also able to access JSON properties that haven't been defined in
+ *    the class property map. In that case, they are treated as undefined and
+ *    untyped (`mixed`) and there won't be any automatic type-conversion of such
+ *    properties, but it can still be handy in a pinch.
+ *
+ *  - There are lots of data export/output options for your object's JSON data,
+ *    to get it back out of the object again: As a multi-level array, as nested
+ *    stdClass objects, or as a JSON string representation of your object.
+ *
+ *  - We include a whole assortment of incredibly advanced debugging features:
+ *
+ *    You can run the constructor with `$requireAnalysis` to ensure that all
+ *    of your JSON data is successfully mapped according to your class property
+ *    map, and that you haven't missed defining any properties that exist in the
+ *    data. In case of any problems, the analysis message will give you a full
+ *    list of all problems encountered in your entire JSON data hierarchy.
+ *
+ *    For your class property maps themselves, you can run functions such as
+ *    `printPropertyDescriptions()` to see a complete list of all properties and
+ *    how they are defined. This helps debug your class inheritance and imports
+ *    to visually see what your final class map looks like, and it also helps
+ *    users see all available properties and all of their virtual functions.
+ *
+ *    And for the JSON data, you can use functions such as `printJson()` to get
+ *    a beautiful view of all internal JSON data, which is incredibly helpful
+ *    when you (or your users) need to figure out what's available inside the
+ *    current object instance's data storage.
+ *
+ *  - A fine-grained and logical exception-system which ensures that you can
+ *    always trust the behavior of your objects and can catch problems easily.
+ *    And everything we throw is _always_ based on `LazyJsonMapperException`,
+ *    which means that you can simply catch that single "root" exception
+ *    whenever you don't care about fine-grained differentiation.
+ *
+ *  - Clean and modular code ensures stability and future extensibility.
+ *
+ *  - Deep code documentation explains everything you could ever wonder about.
+ *
+ *  - Lastly, we implement super-efficient object serialization. Everything is
+ *    stored in a tightly packed format which minimizes data size when you need
+ *    to transfer your objects between runtimes.

+     * would without the cache. However, they're still very fast even without a
+     * cache, and you may be accessing so many different properties that you'd
+     * prefer to avoid a cache for memory reasons (if you prefer lower memory
+     * needs over pure speed). The choice is yours.
+     *
+     * To calculate the memory needs of your own project's virtual function
+     * cache, you simply need to know that an average cache entry uses ~248.6
+     * bytes of RAM on PHP 7 and ~510.4 bytes on PHP 5. Note that the size per
+     * name translation is small enough to be measured in BYTES (NOT kilobytes)!
+     *
+     * Those averages were calculated from a huge sample-size of 10000 function
+     * names, and are very accurate for real-world JSON data.
+     *
+     * To calculate your own cache memory size, think about how many different
+     * JSON properties you'll need to access in your project. Most normal
+     * projects would probably only access at most 100 different property names
+     * (such as `getComments`, `setTime`, etc), since you most likely won't
+     * access every property in the JSON data. So only count the properties
+     * you'll access. And also remember that identical property names used
+     * across different classes, and all the different functions for accessing
+     * the same property, will still only require a SINGLE global cache entry
+     * per property name.
+     *
+     * The storage needs for 100 different property name translations would be
+     * as follows. As you can see, the cache is very memory-efficient:
+     *
+     * - PHP 7: 100x ~248.6 bytes = 24 860 bytes (~24.9 kilobytes).
+     * - PHP 5: 100x ~510.4 bytes = 51 040 bytes (~51.1 kilobytes).
+     *
+     * (If you're still using PHP 5, you should really consider upgrading to
+     * PHP 7 with its better memory efficiency and its much faster engine!)
+     *
+     * It is highly recommended to use caching, and it is enabled by default
+     * unless you override the constant in your class, as follows:
+     *
+     *   ```php
+     *   class MyUncachedLazyJsonMapper extends LazyJsonMapper
+     *   {
+     *       const USE_MAGIC_LOOKUP_CACHE = false;
+     *   }
+     *   ```
+     *
+     * With the above code, `MyUncachedLazyJsonMapper` (and anything extending
+     * from it) would run without using the magic function translation cache,
+     * which means that all magic "virtual function" calls on instances of that
+     * class would have to redo their property translations every time.
+     *
+     * @var bool
+     */
+    const USE_MAGIC_LOOKUP_CACHE = true;
+
+    /**
+     * Tells us how to map JSON properties to internal PHP types or objects.
+     *
+     * This constant can be overridden in your subclasses, to add custom JSON
+     * mapping definitions to your class. It is recommended to always do so.
+     *
+     * The value must be an array of key-value pairs, where the key is the name
+     * of a JSON property and the value is a string with the definition for that
+     * specific property in PHPdoc-style. We will then perform automatic, strict
+     * lazy-conversion of the value to the target type whenever you access that
+     * property. (However, be aware that we always allow `NULL` values in any
+     * property, and will never enforce/convert those to the target type.)
+     *
+     * The following built-in types are supported: `bool`, `int`, `float`,
+     * `string`. The JSON data will be type-converted to match that type.
+     *
+     * Note that if the type is set to `mixed` or an empty string `""` instead,
+     * then the property will allow any of the built-in types (`bool`, `int`,
+     * `float`, `string`, `NULL` (as always) and multi-level arrays of any of
+     * those types). There simply won't be any "forced" type-conversion to any
+     * specific basic type for that property since you haven't defined any
+     * strict type.
+     *
+     * Setting up untyped properties is still useful even if you don't know its
+     * type, since defining the property in the class map ensures that you can
+     * always get/set/access/use that property even if it's unavailable in the
+     * current object instance's internal JSON data.
+     *
+     * You can also map values to objects. In the case of objects (classes), the
+     * classes MUST inherit from `LazyJsonMapper` so they support all necessary
+     * mapping features. To assign a class to a property, you can either write a
+     * FULL (global) class path starting with a leading backslash `\`, such as
+     * `\Foo\Bar\Baz`. Alternatively, you can use a RELATIVE path related to the
+     * namespace of the CURRENT MAP'S class, such as `Bar\Baz` (if your current
+     * class is `\Foo\Whatever`, then it'd be interpreted as `\Foo\Bar\Baz`).
+     * Anything that DOESN'T start with a leading backslash is interpreted as a
+     * relative class path! Just be aware that your class `use`-statements are
+     * completely ignored since PHP has no mechanism to let us detect those.
+     *
+     * It's also possible to map properties to the core `LazyJsonMapper` object
+     * if you simply want an object-oriented container for its data without
+     * writing a custom class. You can do that by defining the property type as
+     * either `\LazyJsonMapper\LazyJsonMapper`, or as `LazyJsonMapper` (which is
+     * a special shortcut that ALWAYS resolves to the core class). But it's
+     * always best to write a proper class, so that its properties are reliable.
+     *
+     * Lastly, you can map "arrays of TYPE" as well. Simply add one or more `[]`
+     * brackets to the end of the type. For example, `int[]` means "array of
+     * ints", and `\Foo[][][]` means "array of arrays of arrays of `\Foo`
+     * objects". It may be easier to understand those mentally if you read them
+     * backwards and say the words "array of" every time you see a `[]` bracket.
+     * (Note: You can also use the array notation with `mixed[][]`, which would
+     * then strictly define that the value MUST be mixed data at an exact depth
+     * of 2 arrays, and that no further arrays are allowed deeper than that.)
+     *
+     * The assigned types and array-depths are STRICTLY validated. That's an
+     * integral part of the `LazyJsonMapper` container, since it guarantees your
+     * class property map interface will be strictly followed, and that you can
+     * fully TRUST the data you're interacting with. If your map says that the
+     * array data is at depth 8 and consists of `YourObject` objects, then we'll
+     * make sure the data is indeed at depth 8 and their value type is correct!
+     *
+     * That goes for arrays too. If you define an `int[]` array of ints, then
+     * we'll ensure that the array has sequential numeric keys starting at 0 and
+     * going up without any gaps, exactly as a JSON array is supposed to be. And
+     * if you define an object `YourObject`, then we'll ensure that the input
+     * JSON data consists of an array with associative keys there (which is used
+     * as the object properties), exactly as a JSON object is supposed to be.
+     *
+     * In other words, you can TOTALLY trust your data if you've assigned types!
+     *
+     * Example property map:
+     *
+     * ```php
+     * const JSON_PROPERTY_MAP = [
+     *     'some_string'              => 'string',
+     *     'an_object'                => '\YourProject\YourObject',
+     *     'array_of_numbers'         => 'int[]',
+     *     'array_of_objects'         => 'RelativeObject[]',
+     *     'untyped_value'            => '', // shorthand for 'mixed' below:
+     *     'another_untyped_value'    => 'mixed', // allows multilevel arrays
+     *     'deep_arr_of_arrs_of_int'  => 'int[][]',
+     *     'array_of_mixed'           => 'mixed[]', // enforces 1-level depth
+     *     'array_of_generic_objects' => 'LazyJsonMapper[]',
+     * ];
+     * ```
+     *
+     * Also note that we automatically inherit all of the class maps from all
+     * parents higher up in your object-inheritance chain. In case of a property
+     * name clash, the deepest child class definition of it takes precedence.
+     *
+     * It is also worth knowing that we support a special "multiple inheritance"
+     * instruction which allows you to "import the map" from one or more other
+     * classes. The imported maps will be merged onto your current class, as if
+     * the entire hierarchy of properties from the target class (including the
+     * target class' inherited parents and own imports) had been "pasted inside"
+     * your class' property map at that point. And you don't have to worry
+     * about carefully writing your inheritance relationships, because we have
+     * full protection against circular references (when two objects try to
+     * import each other) and will safely detect that issue at runtime whenever
+     * we try to compile the maps of either of those bad classes with their
+     * badly written imports.
+     *
+     * The instruction for importing other maps is very simple: You just have to
+     * add an unkeyed array element with a reference to the other class. The
+     * other class must simply refer to the relative or full path of the class,
+     * followed by `::class`.
+     *
+     * Example of importing one or more maps from other classes:
+     *
+     * ```php
+     * const JSON_PROPERTY_MAP = [
+     *     'my_own_prop'                     => 'string',
+     *     OtherClass::class,                // relative class path
+     *     'redefined_prop'                  => float,
+     *     \OtherNamespace\SomeClass::class, // full class path
+     * ];
+     * ```
+     *
+     * The imports are resolved in the exact order they're listed in the array.
+     * Any property name clashes will always choose the version from the latest
+     * statement in the list. So in this example, our class would first inherit
+     * all of its own parent (`extends`) class maps. Then it would add/overwrite
+     * `my_own_prop`. Then it imports everything from `OtherClass` (and its
+     * parents/imports). Then it adds/overwrites `redefined_prop` (useful if you
+     * want to re-define some property that was inherited from the other class).
+     * And lastly, it imports everything from `\OtherNamespace\SomeClass` (and
+     * its parents/imports). As long as there are no circular references,
+     * everything will compile successfully and you will end up with a very
+     * advanced final map! And any other class which later inherits from
+     * (extends) or imports YOUR class will inherit the same advanced map from
+     * you! This is REAL "multiple inheritance"! ;-)
+     *
+     * Also note that "relative class path" properties are properly inherited as
+     * pointing to whatever was relative to the original inherited/imported
+     * class where the property was defined. You don't have to worry about that.
+     *
+     * The only thing you should keep in mind is that we ONLY import the maps.
+     * We do NOT import any functions from the imported classes (such as its
+     * overridden functions), since there's no way for us to affect how PHP
+     * resolves function calls to "copy" functions from one class to another. If
+     * you need their functions, then you should simply `extends` from the class
+     * to get true PHP inheritance instead of only importing its map. Or you
+     * could just simply put your functions in PHP Traits and Interfaces so
+     * that they can be re-used by various classes without needing inheritance!
+     *
+     * Lastly, here's an important general note about imports and inheritance:
+     * You DON'T have to worry about "increased memory usage" when importing or
+     * inheriting tons of other classes. The runtime "map compiler" is extremely
+     * efficient and re-uses the already-compiled properties inherited from its
+     * parents/imports, meaning that property inheritance is a ZERO-COST memory
+     * operation! In fact, re-definitions are also zero-cost as long as your
+     * class re-defines a property to the exact same type that it had already
+     * inherited/imported. Such as `Base: foo:string, Child: foo:string`. In
+     * that case, we detect that the definitions are identical and just re-use
+     * the compiled property from `Base` instead. It's only when a class adds
+     * NEW/MODIFIED properties that memory usage increases a little bit! In
+     * other words, inheritance/imports are a very good thing, and are always a
+     * better idea than manually writing similar lists of properties in various
+     * unrelated (not extending each other) classes. In fact, if you have a
+     * situation where many classes need similar properties, then it's a GREAT
+     * idea to create special re-usable "property collection" classes and then
+     * simply importing THOSE into ALL of the different classes that need those
+     * sets of properties! You can even use that technique to get around PHP's
+     * `use`-statement limitations (simply place a "property collection" class
+     * container in the namespace that had all of your `use`-classes, and define
+     * its properties via easy, relative paths there, and then simply make your
+     * other classes import THAT container to get all of its properties).
+     *
+     * As you can see, the mapping and inheritance system is extremely powerful!
+     *
+     * Note that the property maps are analyzed and compiled at runtime, the
+     * first time we encounter each class. After compilation, the compiled maps
+     * become immutable (cannot be modified). So there's no point trying to
+     * modify this variable at runtime. That's also partially the reason why
+     * this is defined through a constant, since they prevent you from modifying
+     * the array at runtime and you believing that it would update your map. The
+     * compiled maps are immutable at runtime for performance & safety reasons!
+     *
+     * Have fun!

+     * This is where you can perform your custom subclass initialization, since
+     * you are unable to override the main constructor.
+     *
+     * We automatically run this function at the end of the normal constructor,
+     * as well as every time that you manually use `assignObjectData()` to
+     * replace the object's data. (When new data is assigned, you should treat
+     * yourself as a new object, which is why `_init()` will run again.)
+     *
+     * `WARNING:` Please RESIST the urge to touch ANY of the internal JSON data
+     * during this initialization. All data will always be automatically
+     * validated during actual retrieval and setting, so you can always trust
+     * that the final types WILL match your class property map definitions.
+     *
+     * Remember that any extra work you do in `_init()` will run EVERY time an
+     * instance of your object is created, even when those objects live within a
+     * main object. So if your function is heavy, it will slow down operation of
+     * the class; and your parsing of the properties would be counter-productive
+     * against the goal of "lazy parsing" of JSON data on a when-accessed basis!
+     *
+     * Instead, it's preferable to just override specific property getter and
+     * setter functions, to make your class return different default values if a
+     * certain internal data field is missing an expected value. But in general,
+     * your ultimate USER CODE should be responsible for most of THAT checking,
+     * by simply looking for `NULL` (denoting a missing value in the JSON data
+     * container), and then deciding what to do with that in your final project.
+     *
+     * Lastly, there are a few rules that MUST be followed by your `_init()`:
+     *
+     *  1. As explained above, but worth repeating again: Your `LazyJsonMapper`
+     *  classes are supposed to be LIGHT-weight "JSON data containers". So
+     *  please DO NOT treat this as a "standard class constructor". The more
+     *  work you do in `_init()`, the slower your object creation is. And since
+     *  your object is a JSON container which is automatically created from
+     *  data, you can expect LOTS of instances of your class to be created
+     *  during normal runtime! That's also why your `_init()` function does not
+     *  get any parameters! That is to discourage misuse as a normal class.
+     *
+     *  Also remember that you may not even need `_init()`, since you can simply
+     *  give your properties default values instead of using `_init()`, such as
+     *  by writing `public $myproperty = true;`. All instances of that object
+     *  would then start with that value set to `TRUE` by default.
+     *
+     *  2. You can ONLY throw `LazyUserException`. All other exceptions will be
+     *  blocked and turned into a generic `LazyUserException`. This is done to
+     *  ensure that your custom init function cannot break the contract that the
+     *  `LazyJsonMapper` constructor guarantees in its listed exceptions.
+     *
+     *  (That's also the reason why all built-in functions except `_init()` are
+     *  marked `final`: So that subclasses cannot break the `LazyJsonMapper`
+     *  API/interface contract. If something IS a `LazyJsonMapper`, it MUST
+     *  behave as a `LazyJsonMapper`, and the `final` functions guarantee that!)
+     *
+     *  3. If your class extends from `LazyJsonMapper`, then there's no need to
+     *  call `parent::_init()` (since our core `_init()` does nothing). But if
+     *  you extend from ANY OTHER CLASS, you MUST call your parent's init BEFORE
+     *  doing any work, just to guarantee that your WHOLE parent-class hierarchy
+     *  is fully initialized first.
+     *
+     *  4. Understand and accept the fact that your personal class properties
+     *  will NOT be serialized if you serialize an object. Only the JSON data
+     *  array will be kept. The `_init()` function will be called again when you
+     *  unserialize the object data, as if your object had just been created for
+     *  the first time. This is done to save space and to discourage misuse
+     *  of your `LazyJsonMapper` containers.
+     *
+     *  Remember that your classes are supposed to be lightweight JSON data
+     *  containers, which give you a strongly typed, automatic, object-oriented
+     *  interface to your data. Classes "with advanced constructors and tons of
+     *  properties" are NOT suitable as JSON containers and belong ELSEWHERE in
+     *  the rest of your project!
+     *
+     * @throws LazyUserException If there is any fatal error which prevents
+     *                           initialization. This stops object construction
+     *                           if this is the initial construction. However,
+     *                           it doesn't affect data-assignment if you throw
+     *                           during a later `assignObjectData()` call.

+     * copying and data conversion from our internal object representation.
+     *
+     * Note that the conversion process will recursively validate and convert
+     * all properties in the entire internal data hierarchy. You can trust that
+     * the returned result will be perfectly accurate and follow your class map
+     * property type-rules. This does however mean that the data may not be the
+     * same as the input array you gave to `__construct()`. For example, if your
+     * input contained an array `["1", "2"]` and your type definition map says
+     * that you want `int` for that property, then you'd get `[1, 2]` as output.
+     *
+     * The conversion is always done on a temporary COPY of the internal data,

+     * object then please DON'T do that. Look at `asJson()` instead, which gives
+     * you full control over all JSON output parameters and properly handles the
+     * conversion in all scenarios, without you needing to do any manual work.

+     * This lets you analyze the object data & map to look for the following:
+     *
+     *  1. Undefined JSON properties that need to be defined in your classes
+     *  so that their existence becomes permanent and therefore safer to use
+     *  (since defined properties are always retrievable even if they don't
+     *  exist in the current object instance's data). And actually defining
+     *  the properties is also the ONLY way that you can enforce a specific
+     *  data-type, since undefined properties default to untyped (`mixed`).
+     *
+     *  2. Bad class map definitions that don't match the actual JSON data.
+     *  It does this by checking all of the encountered classes within the JSON
+     *  data to ensure that they construct successfully (which they ALWAYS
+     *  will, unless the user has overridden `_init()` and throws from it), as
+     *  well as verifying that all basic PHP type coercions work, and that the
+     *  data is formatted as-described in the definition (such as having the
+     *  correct array-depth, or data defined as objects actually being objects).
+     *
+     * The scan is performed by looking at EVERY item in the object's internal
+     * JSON data array, and checking for a corresponding class map definition
+     * (if nothing exists, it's treated as "missing from the class map"), and
+     * then attempting conversion to its specified type (if that fails, it's
+     * treated as "bad class map definition"). All undefined values (which lack
+     * any class map definition) are ALSO validated as if they were `mixed`,
+     * to ensure that NOTHING can contain illegal values.
+     *
+     * If a recursive scan is requested, then all sub-objects (`LazyJsonMapper`
+     * data containers) will ALSO recursively perform the same analysis on their
+     * own internal data, so that the whole JSON data tree is recursively
+     * verified. Their analysis results will be merged with our return value.
+     *
+     * Note that calling this function will cause the WHOLE object tree to be
+     * constructed and ALL of its mapped properties to be converted/parsed to
+     * verify the class map, which takes some time and permanently increases the
+     * object's memory usage (since conversion causes any internal sub-objects
+     * to be stored as actual objects instead of merely as plain sub-arrays)!
+     *
+     * Therefore, you should ONLY use this function when necessary: When you
+     * need advanced and powerful debugging of your class maps!

+     * what you do with your reference). However, you A) don't have to worry
+     * about invalid data, because it will all get validated at the next
+     * `_getProperty()` call again, and B) you have to explicitly bind the
+     * returned value by reference to actually risk affecting the internal
+     * data, as explained below.
+     *
+     * Method 1 (recommended for almost 100% of all usages, safest):
+     *
+     *  ```php
+     *  $val = $this->_getProperty('foo'); // Copy-on-write assignment to $val.
+     *  $val = 'bar'; // Does NOT modify the internal data "foo" property.
+     *  ```
+     *
+     * Method 2 (dangerous, and this example even contains an intentional bug):
+     *
+     *  ```php
+     *  $val = &$this->_getProperty('foo'); // Reference assignment to $val.
+     *  $val = 'bar'; // Direct link, thus modifies the internal "foo" property.
+     *  ```
+     *
+     * `SERIOUS WARNING:` If you use Method 2, do NOT use the code above. It was
+     * just explained that way to demonstrate a SERIOUS MISTAKE. If you assign
+     * by reference, you obviously intend to link directly to internal data. But
+     * the code above fails if no internal data for that property exists yet. In
+     * that case, the code above will write to a temporary `NULL` variable which
+     * is not linked at all to the object. Instead, you MUST ALWAYS use
+     * `$createMissingValue = true` if you want TRUSTABLE data references.
+     *
+     * Method 2 (the CORRECT way of writing it):
+     *
+     *  ```php
+     *  $val = &$this->_getProperty('foo', true);
+     *  $val = 'bar';
+     *  ```
+     *
+     * That FIXED code will create the property and put `NULL` in it if it's
+     * missing from the internal data, and then returns the reference to the
+     * created internal data entry. It's the ONLY way to ensure REAL references.
+     *
+     * Note that there is ZERO PERFORMANCE BENEFIT of assigning our return-value
+     * by reference. ONLY use references if you have an ADVANCED reason for it!
+     * Internally, PHP treats both assignment types identically until the moment
+     * you try to write to/modify the contents of the variable. So if you are
+     * only reading, which is most of the time, then there's no reason to use a
+     * reference. And never forget that modifying via direct reference lets you
+     * write invalid data (which won't be detected until a `_getProperty()`
+     * call attempts to read that bad data again), as mentioned earlier.
+     *
+     * There is one final warning: If YOU have a "return-by-reference" function,
+     * then you will AUTOMATICALLY return a direct link to the inner data if you
+     * use us directly in your return statement. Here's an example of that:
+     *
+     *  ```php
+     *  public function &myFunction() { // <-- Note the "&" return-by-ref here!
+     *      // returns reference to real internal data OR temp var (badly coded)
+     *      return $this->_getProperty('foo'); // <-- VERY DANGEROUS BUG!
+     *
+     *      // returns reference to real internal data (correctly coded)
+     *      return $this->_getProperty('foo', true); // <-- CORRECT!
+     *
+     *      // you can also intentionally break the link to the internal data,
+     *      // by putting it in a copy-on-write variable and returning THAT:
+     *      $copyOnWrite = $this->_getProperty('foo'); // copy-on-write (no ref)
+     *      return $copyOnWrite; // ref to $copyOnWrite but not to real internal
+     *  }
+     *  ```
+     *
+     * @param string $propName           The property name.
+     * @param bool   $createMissingValue If `TRUE` then we will create missing
+     *                                   internal object data entries (for
+     *                                   class-defined properties) and store a
+     *                                   `NULL` in them. This will "pollute" the
+     *                                   internal data with default `NULL`s for
+     *                                   every missing property that you attempt
+     *                                   to retrieve, but it's totally NECESSARY
+     *                                   if you intend to use the return-value
+     *                                   by-reference, since we MUST store the

+     *                                   returned reference to link to our

+     * if no value exists, so that we can link PHP to a true reference to the
+     * internal data. Obviously we can't link to something that doesn't exist,
+     * which is why we MUST create `NULL` values. Unfortunately that means that
+     * "virtual property access" will lead to increased memory usage and worse
+     * JSON output (due to all the added values) if you want to export the
+     * internal data as JSON later.
+     *
+     * The recommended access method, `$obj->getFoo()` ("virtual functions")
+     * doesn't have that problem. It ONLY happens when you decide to use
+     * `$obj->foo` for "direct virtual property" access.
+     *
+     * There are several other quirks with "direct virtual properties", due to
+     * how PHP works. If you don't write your code carefully, you may cause
+     * serious issues with performance or unexpected results.
+     *
+     * All of the important quirks are as follows:
+     *
+     *  1. The aforementioned necessary `NULL` value insertion increases memory
+     *  usage and may lead to unexpected problems if you convert back to JSON,
+     *  such as if the server does not expect those values to exist with `NULL`.
+     *
+     *  2. Anytime you use the array `[]` access operator on the outer property
+     *  name, PHP will trigger a `__get()` call, which of course does its whole
+     *  data-validation again. The following would therefore be EXTREMELY SLOW,
+     *  and possibly even DANGEROUS (since you're manipulating the array while
+     *  looping over its keys while constantly triggering `__get()` re-parsing):
+     *
+     *    ```php
+     *    foreach ($obj->something as $k => $v) {
+     *        // Every assignment here will do __get('something') which parses
+     *        // the array over and over again before each element is modified:
+     *        $obj->something[$k] = 'foo';
+     *    }
+     *    ```
+     *
+     *  The proper way to solve THAT is to either save a reference to
+     *  `$obj->something` as follows:
+     *
+     *    ```php
+     *    $ref = &$obj->something; // Calls __get('something') a single time.
+     *    foreach ($ref as $k => $v) {
+     *        $ref[$k] = 'foo'; // Changes array directly via stored reference.
+     *    }
+     *    ```
+     *
+     *  Or to loop through the input values as follows:
+     *
+     *    ```php
+     *    foreach ($obj->something as &$v) { // Note the "&" symbol.
+     *        $v = 'foo'; // Changes array value directly via reference.
+     *    }
+     *    ```
+     *
+     *  3. Anytime you use a reference, there will be NO DATA VALIDATION of the
+     *  new value you are inputting. It will not be checked again UNTIL the next
+     *  internal `_getProperty()` call for that property (ie. by the next
+     *  `__get()`) so you may therefore unintentionally insert bad data that
+     *  doesn't match the class definition map:
+     *
+     *    ```php
+     *    // Saving a reference to internal data and then changing that variable
+     *    // will directly edit the value without letting us validate it:
+     *
+     *    $ref = &$obj->some_string; // Make "$ref" into a reference to data.
+     *    $ref = new InvalidObject(); // Writes a bad value directly to memory.
+     *    var_dump($obj->some_string); // Throws error because of bad data.
+     *
+     *    // The same is true about array access. In this case, PHP does
+     *    // __get('some_int_array') and finds an array, and then it directly
+     *    // manipulates that array's memory without letting us validate it:
+     *
+     *    $obj->some_int_array[] = new InvalidObject();
+     *    $obj->some_int_array[15] = new InvalidObject();
+     *    var_dump($obj->some_int_array); // Throws error because of bad data.
+     *    ```
+     *
+     *  4. You can always trust that `__set()` assignments WILL be validated.
+     *  But a `__set()` ONLY happens when you assign with the equals operator
+     *  (`=`) to a pure property name WITHOUT any array access (`[]`) operators.
+     *
+     *    ```php
+     *    $obj->some_property = '123'; // Calls __set() and validates new value.
+     *    $obj->an_array[] = '123' // Calls __get() and won't validate changes.
+     *    ```
+     *
+     * These quirks of "virtual direct property access" are quite easy to deal
+     * with when you know about them, since almost all of them are about array
+     * access, and the rest are about intentional misuse by binding directly to
+     * references. Just avoid making those mistakes.
+     *
+     * However, in general, you should REALLY be using the "virtual function"
+     * access method instead, which allows you to do great things such as
+     * overriding certain class property-functions (ie `getSomething()`) with
+     * your own custom behaviors, so that you can do extra validation, get/set
+     * value transformations, and other fantastic things!
+     *
+     * It is possible (and recommended) to disable virtual properties via the
+     * `ALLOW_VIRTUAL_PROPERTIES` class constant. The feature is only enabled by
+     * default because it helps people easily migrate from legacy projects.

+     * legally generate such function names. Instead, we'll encode the operators
+     * with a sequence that will never appear in our normal algorithm's output.
+     *
+     * For example, if the user has a property named `en-US`, our special
+     * operator translation will give it a function name of `getEn_x2D_US()`
+     * to safely encode the arithmetic minus symbol.
+     *
+     * This encoding scheme was deliberately chosen thanks to the fact that it
+     * will never conflict with anything else that's legitimately generated by
+     * our algorithm. Because if the user has a property that's _actually_ named
+     * `en_x2D_US`, then that one would be encoded as `getEnX2D_US()` (by the
+     * main `PropertyTranslation` algorithm), which is obviously not the same
+     * thing and will never confuse our parser in decoding later. And if they
+     * sent us `en__x2D_US`, it would be encoded as `getEn_X2D_US()`, which is
+     * yet again different (the `X` is uppercase in that situation too).
+     *
+     * Therefore, our special encoding of `_x[HEX]_` will never be generated by
+     * any legitimate user property names, even if those names do contain that
+     * sequence on-disk. They'll all be encoded to something else. The only
+     * thing that can put a lowercase `x` in this particular arrangement is our
+     * own operator symbol translator here.
+     *
+     * As for why we need that long sequence instead of something shorter, it's
+     * unfortunately the only way that we can guarantee uniqueness. It relies on
+     * the principle that `_x` in the user's own properties would ALWAYS be
+     * encoded as `X`. Most programmers are familiar with hex codes and will
+     * recognize the sequences we've chosen: `getEn_x2D_US()`, where `x` stands
+     * for "hex", and `2D` is the hex character value for the minus symbol.
+     *
+     * This particular encoding also allows us to easily encode future illegal
+     * characters of any length (even multiple bytes such as `_xFFFF_` if ever
+     * necessary) without needing to change the encoding scheme again.

+     *
+     * That extra protection does however also mean that your runtime's initial

+        // current inheritance/import chain are resolved. THEN it's safe to
+        // begin compiling any other encountered classes from the properties...
+        //
+        // The solution is "simple": Build a list of the class-paths of all
+        // encountered UNCOMPILED property classes within our own map tree and
+        // within any imports (which are done via recursive compile-calls). To
+        // handle imports, we simply ensure that our compile-function (this one)

+        // from properties" so that we'll let it bubble up all the way to the
+        // root class/call that began the whole compile-chain. And then just let
+        // that root-level call resolve ALL uncompiled properties from the
+        // ENTIRE tree by simply compiling the list of property-classes one by
+        // one if they're still missing. That way, we'll get full protection
+        // against uncompilable class-properties ANYWHERE in our tree, and we'll
+        // do it at a totally safe time (at the end of the main compilation call
+        // that kicked everything off)!

+        // done. That's intended to make the list as light-weight as possible

+### Notes:
+We will close your feature request, sometimes without answering, if any of the following are met:
+* You requested a endpoint/function for `challenge_required`, `checkpoint_required`, `feedback_required` or `sentry_block` errors. These are decidedly unsupported, and will not be added
+* You requested a endpoint/function for an iOS feature. This API emulates the Android API, therefore we cannot, *safely*, add endpoints/functions which are not in the Android app.
+* You are using the wrong issue template
+
+Please make sure you have done the following before submitting your feature request:
+* You have [Searched](https://github.com/mgp25/Instagram-API/search?type=Issues) the bug-tracker for the same feature request

+
+### Description
+Please include a well-worded description of your feature request. Please make sure to include where on the app this feature is acceptable so we can reproduce it. Additionally, it would make our lives easier if you are able to post the endpoint, its associated parameters, and response.

+## What should I know before I get started?
+
+### Code of Conduct
+
+This project adheres to the Contributor Covenant [code of conduct](CODE_OF_CONDUCT.md).
+By participating, you are expected to uphold this code.
+Please report any unacceptable behavior.
+
+## Basic rules
+
+Important! Your contributions must follow all of these rules for a consistent and bug-free project.
+
+This is a document which, among other things, describes PSR-4 class autoloading, clean commits, how to handle/document exceptions, how to structure function arguments, naming clear variables, always adding/updating PHPdoc blocks in all affected functions, and how to verify that your changes don't _break everything_ when performing big changes to existing functions or adding brand new functions and classes.
+
+
+### Git Setup
+
+If you are using a Linux/Mac/Unix system, you **MUST** install our git-hook in your local repository. It will help prevent you from accidentally committing badly formatted code. Please run the following command in the project's root folder (the folder which has files like `README.md` etc), to install the hook in your repository:
+
+```
+ln -fs "../../.pre-commit.hook" .git/hooks/pre-commit
+```
+
+
+### Codestyle Command
+
+Before committing any work, you **MUST** always run the codestyle fixer command in the root folder of the repository:
+
+```
+composer codestyle
+```
+
+That command will automatically fix all codestyle issues as well as generate various documentation, such as the class docs for all of the Responses and Model items.
+
+
+### Available Tasks
+
+Please visit our [Project Task Tracker](https://github.com/mgp25/Instagram-API/projects), where contributors can look at the list of available work. High-quality code contributions are greatly appreciated.
+
+
+### Commits
+
+- You **MUST** try to **separate** work into smaller commits. So if you `"changed Utils.php to fix getSeconds and changed Request.php to fix Request()"`, then make **TWO SEPARATE COMMITS**, so that we can easily find your changes in the project history, and can easily revert any individual broken changes without losing tons of other code too! So remember: 1 commit per task. :smile:
+
+- Use the detailed description field of your commit, to document why you did certain changes if it's not an obvious change (such as a typo fix). Your description gets added to the history of the project so that we can know what you were thinking, if we need to check the change again later.
+
+- **Name** your single-file commits `"AffectedClassName: Change description"` and keep the total length of the summary line at 50 characters or less in total (the Git/GitHub standard).
+
+- If your change NEEDS to affect multiple files, then it is SOMETIMES okay to leave out the classname part from the summary, but in that case you _must_ write a very clear and descriptive summary to explain it. _But_ usually you _should_ still include the classname even for multi-file edits. For example, renaming a function in Utils and having to change the name of it in other files is still a `"Utils: Renamed bleh() to bloop()"` commit.
+
+Examples of BAD commit summaries:
+
+```
+Edit something
+Fix this
+Utils+request changes
+```
+
+Examples of GOOD commit summaries:
+
+```
+Utils: Fix formatting of getSeconds
+Request: Send cropping information
+Changed all number_format() to round() everywhere
+Response: Parse timestamps as floats
+```
+
+
+### Modifying anything in the existing code
+
+- If you want to change a public API function's parameters (particularly in `src/Instagram.php`), think EXTREMELY hard about NOT doing it. And if you absolutely MUST do it (such as adding an important new parameter), then you MUST add it in a BACKWARDS-COMPATIBLE WAY, by adding it as the LAST parameter of the argument list AND providing a sensible DEFAULT VALUE for it so that people's CURRENT projects based on this library continue working and DON'T BREAK due to your function definition changes!
+
+- Do NOT look at your changes in isolation. Look at the BIG PICTURE of what your change now does to the REST of the codebase.
+
+- For example, if you change the returned variable type from a function (such as from an `"int"` to a `"string"`), then you MUST update the function's PHPdoc block to document the new return value (with `@return string`), and you MUST also slowly and carefully check ALL OTHER CODE that relied on the OLD behavior of that function. There's a command-line tool called "grep" (or an even better one especially made for programmers, called ["ag" aka "the silver searcher"](https://github.com/ggreer/the_silver_searcher)) to search for text in files. USE IT to check ALL other code locations that called your modified function, and make sure that you didn't break ANY of them AT ALL!
+
+- In fact, ANY TIME that you change a function's ARGUMENTS, RETURN VALUE or THROWN EXCEPTIONS (new/deleted ones), then you MUST update the function's PHPdoc block to match the new truth. And you MUST check ALL other functions that CALL your function, and update those too. For example let's say they DON'T handle a new exception you're now throwing, in which case you MUST now update THEIR `@throws` documentation to document the fact that THEY now let yet another exception bubble up. And then you MUST search for the functions that called THOSE updated functions and update THEIR documentation TOO, all the way until you've reached the top and have FULLY documented what exceptions are being thrown in the whole chain of function calls.
+
+- You MUST ALWAYS update the PHPdoc blocks EVERYWHERE that's affected by your changes (whenever you've changed a functions ARGUMENTS or RETURN type or what it THROWS (any new/deleted exceptions)), because imagine if we NEVER update the blocks EVERYWHERE that's affected by your change. We would then have something like `/** @param $a, $b, $c */ function foo ($x)` and sudden, critical exceptions that aren't getting handled and thus KILL the program.
+
+Here's a checklist for what you MUST do to ENSURE totally correct documentation EVERY TIME that you make a CHANGE to a function's ARGUMENTS or RETURN TYPE or EXCEPTIONS of an existing function, OR when you introduce a NEW function whose use is being added to any existing functions.
+
+1. You MUST ALWAYS use grep/ag. Find EVERY other code location that uses your new/modified function.
+
+2. Check: Did your changes just BREAK EVERYTHING somewhere else, which now has to be updated to match? Almost GUARANTEED the answer is YES, and you MUST update the other locations that expected the old function behavior/return type/parameters/exceptions.
+
+3. Check: Do you need to also UPDATE the PHPdoc for those OTHER functions too? OFTEN the answer is YES. For example, if you've changed the exceptions that a deep, internal function throws, then you MUST either catch it in all higher functions and do something with it, OR let it pass through them upwards. And if you do let it pass through and bubble up then you MUST ALSO update the PHPdoc for THAT higher function to say `"@throws TheNewException"` (or delete something in case you changed a subfunction to no longer throw).
+
+4. If your updates to the affected higher-level functions in steps 2/3 means that THOSE other functions now ALSO behave differently (meaning THEY have new return values/exceptions/parameters), then you MUST also do ANOTHER grep/ag to check for anything that uses THOSE functions, and update all of those code locations TOO. And continue that way up the entire chain of functions that call each other, until you reach the top of the project, so that the entire chain of function calls is caught/documented properly. Otherwise, those unexpected (undocumented) exceptions will terminate PHP, so this is very important!
+
+
+
+## Styleguides
+
+### Namespaces
+
+- Organize all classes into logical namespaces.
+
+- We follow the PSR-4 Autoloading standard, which means that you MUST only have ONE class per source code `.php` file. And the namespace AND classname MUST match BOTH its disk path AND its `.php` filename. In our project, the `src/` folder is the `InstagramAPI` namespace, and everything under that is for its subnamespaces (folders) and our classes (PHP files).
+
+Example of a proper class in our top-level namespace:
+
+```php
+src/Something.php:
+<?php
+
+namespace InstagramAPI;
+
+class Something
+{
+    ....
+}
+```
+
+Example of a proper class in a sub-namespace:
+
+```php
+src/Wonderful/Things/Something.php:
+<?php
+
+namespace InstagramAPI\Wonderful\Things;
+
+class Something
+{
+    ....
+}
+```
+
+### Functions and Variables
+
+- You MUST split all function declaration/definition arguments onto separate lines, but only IF the function takes arguments. This is done for clarity, and to avoid unintentional bugs by contributors. It ensures that any changes to function arguments will be diffed as a single-line change. It's more readable. And it's the style _we_ use.
+
+Example of a function that takes no arguments:
+
+```php
+public function doSomething()
+{
+    ...
+}
+```
+
+Example of a function that takes one argument:
+
+```php
+public function doSomething(
+    $foo = null)
+{
+    ...
+}
+```
+
+Example of a function that takes multiple arguments:
+
+```php
+public function doSomething(
+    $foo,
+    $bar = '',
+    $baz = null)
+{
+    ...
+}
+```
+
+- All properties and functions MUST be named using `camelCase`, NOT `snake_case`. (The _only_ exception to this rule is Instagram's server response property objects, meaning everything in the `src/Response/` folder, since _their_ server replies can use underscores.)
+- Private and protected properties/functions MUST be _prefixed_ with an underscore, to clearly show that they are internal inside the class and _cannot_ be used from the outside. But the PUBLIC properties/functions MUST _NEVER_ be prefixed with an underscore (_except_ the _obvious_, specially named, built-in PHP double-underscore ones such as `public function __construct()`). And also note that function _arguments_ (such as in setters) MUST NEVER be prefixed by underscores.
+
+Example of a class with proper function and property underscore prefixes for private/protected members, and with the proper function argument style:
+
+```php
+class Something
+{
+    public $publicProperty;
+    protected $_protectedProperty;
+    private $_privateProperty;
+
+    public function getProtectedProperty()
+    {
+        return $this->_protectedProperty;
+    }
+
+    public function setProtectedProperty(
+        $protectedProperty)
+    {
+        $this->_protectedProperty = $protectedProperty;
+    }
+
+    public function getPublicProperty()
+    {
+        return $this->_publicProperty;
+    }
+
+    public function setPublicProperty(
+        $publicProperty)
+    {
+        $this->publicProperty = $publicProperty;
+    }
+
+    protected function _somethingInternal()
+    {
+        ...
+    }
+
+    ...
+}
+```
+
+- All functions and variables MUST have descriptive names that document their purpose automatically. Use names like `$videoFilename` and `$deviceInfo` and so on, so that the code documents itself instead of needing tons of comments to explain what each step is doing.
+
+Examples of BAD variable names:
+
+```php
+$x = $po + $py;
+$w = floor($h * $ar);
+```
+
+Examples of GOOD variable names:
+
+```php
+$endpoint = $this->url.'?'.http_build_query($this->params);
+$this->_aspectRatio = (float) ($this->_width / $this->_height);
+$width = floor($this->_height * $this->_maxAspectRatio);
+```
+
+- All functions MUST have occasional comments that explain what they're doing in their various substeps. Look at our codebase and follow our commenting style.
+
+- Our comments start with a capital letter and end in punctuation, and describe the purpose in as few words as possible, such as: `// Default request options (immutable after client creation).`
+
+- All functions MUST do as little work as possible, so that they are easy to maintain and bugfix.
+
+Example of a GOOD function layout:
+
+```php
+function requestVideoURL(...);
+
+function uploadVideoChunks(...);
+
+function configureVideo(...);
+
+function uploadVideo(...)
+{
+    $url = $this->requestVideoURL();
+    if (...handle any errors from the previous function)
+
+    $uploadResult = $this->uploadVideoChunks($url, ...);
+
+    $this->configureVideo($uploadResult, ...);
+}
+```
+
+Example of a BAD function layout:
+
+```php
+function uploadVideo(...)
+{
+    // Request upload URL.
+    // Upload video data to URL.
+    // Configure its location property.
+    // Post it to a timeline.
+    // Call your grandmother.
+    // Make some tea.
+    // ...and 500 other lines of code.
+}
+```
+
+- All function parameter lists MUST be well-thought out so that they list the most important arguments FIRST and so that they are as SIMPLE as possible to EXTEND in the FUTURE, since Instagram's API changes occasionally.
+
+Avoid this kind of function template:
+
+```php
+function uploadVideo($videoFilename, $filter, $url, $caption, $usertags, $hashtags);
+```
+
+Make such multi-argument functions take future-extensible option-arrays instead, especially if you expect that more properties may be added in the future.
+
+So the above would instead be PROPERLY designed as follows:
+
+```php
+function uploadVideo($videoFilename, array $metadata);
+```
+
+Now users can just say `uploadVideo($videoFilename, ['hashtags'=>$hashtags]);`, and we can easily add more metadata fields in the future without ever breaking backwards-compatibility with projects that are using our function!
+
+### Function Documentation
+
+- All functions MUST have _COMPLETE_ PHPdoc doc-blocks. The critically important information is the single-sentence `summary-line` (ALWAYS), then the `detailed description` (if necessary), then the `@param` descriptions (if any), then the `@throws` (one for EVERY type of exception that it throws, even uncaught ones thrown from DEEPER functions called within this function), then the `@return` (if the function returns something), and lastly one or more `@see` if there's any need for a documentation reference to a URL or another function or class.
+
+Example of a properly documented function:
+
+```php
+    /**
+     * Generates a User Agent string from a Device (<< that is the REQUIRED ONE-SENTENCE summary-line).
+     *
+     * [All lines after that are the optional description. This function didn't need any,
+     *  but you CAN use this area to provide extra information describing things worth knowing.]
+     *
+     * @param \InstagramAPI\Devices\Device $device The Android device.
+     * @param string[]|null                $names (optional) Array of name-strings.
+     *
+     * @throws \InvalidArgumentException                  If the device parameter is invalid.
+     * @throws \InstagramAPI\Exception\InstagramException In case of invalid or failed API response.
+     *
+     * @return string
+     *
+     * @see otherFunction()
+     * @see http://some-url...
+     */
+    public static function buildUserAgent(
+        Device $device,
+        $names = null)
+    {
+        ...
+    }
+```
+
+- You MUST take EXTREMELY GOOD CARE to ALWAYS _perfectly_ document ALL parameters, the EXACT return-type, and ALL thrown exceptions. All other project developers RELY on the function-documentation ALWAYS being CORRECT! With incorrect documentation, other developers would make incorrect assumptions and _severe_ bugs would be introduced!
+
+### Exceptions
+
+- ALL thrown exceptions that can happen inside a function or in ANY of its SUB-FUNCTION calls MUST be documented as `@throws`, so that we get a COMPLETE OVERVIEW of ALL exceptions that may be thrown when we call the function. YES, that EVEN means exceptions that come from deeper function calls, whose exceptions are NOT being caught by your function and which will therefore bubble up if they're thrown by those deeper sub-functions!
+- Always remember that Exceptions WILL CRITICALLY BREAK ALL OTHER CODE AND STOP PHP'S EXECUTION if not handled or documented properly! They are a LOT of responsibility! So you MUST put a LOT OF TIME AND EFFORT into PROPERLY handling (_catching and doing something_) for ALL exceptions that your function should handle, AND adding PHPdoc _documentation_ about the ones that your function DOESN'T catch/handle internally and which WILL therefore bubble upwards and would possibly BREAK other code (which is EXACTLY what would happen if an exception ISN'T documented by you and someone then uses your bad function and doesn't "catch" your exception since YOU didn't tell them that it can be thrown)!
+- All of our internal exceptions derive from `\InstagramAPI\Exception\InstagramException`, so it's always safe to declare that one as a `@throws \InstagramAPI\Exception\InstagramException` if you're calling anything that throws exceptions based on our internal `src/Exception/*.php` system. But it's even better if you can pinpoint which exact exceptions are thrown, by looking at the functions you're calling and seeing their `@throws` documentation, WHICH OF COURSE DEPENDS ON PEOPLE HAVING WRITTEN PROPER `@throws` FOR THOSE OTHER FUNCTIONS SO THAT _YOU_ KNOW WHAT THE FUNCTIONS YOU'RE CALLING WILL THROW. DO YOU SEE _NOW_ HOW IMPORTANT IT IS TO DECLARE EXCEPTIONS PROPERLY AND TO _ALWAYS_ KEEP THAT LIST UP TO DATE
+- Whenever you are using an EXTERNAL LIBRARY that throws its own custom exceptions (meaning NOT one of the standard PHP ones such as `\Exception` or `\InvalidArgumentException`, etc), then you MUST ALWAYS re-wrap the exception into some appropriate exception from our own library instead, otherwise users will not be able to say `catch (\InstagramAPI\Exception\InstagramException $e)`, since the 3rd party exceptions wouldn't be derived from our base exception and wouldn't be caught, thus breaking the user's program. To solve that, look at the design of our `src/Exception/NetworkException.php`, which we use in `src/Client.php` to re-wrap all Guzzle exceptions into our own exception type instead. Read the source-code of our NetworkException and it will explain how to properly re-wrap 3rd party exceptions and how to ensure that your re-wrapped exception will give users helpful messages and helpful stack traces.
+
+
+# Contributing new endpoints
+
+In order to add endpoints to the API you will need to capture the requests first. For that, you can use any HTTPS proxy you want. You can find a lot of information about this on the internet. Remember that you need to install a root CA (Certificate Authority) in your device so that the proxy can decrypt the requests and show them to you.
+
+Also be aware that you cannot capture Instagram for iPhone's requests. The iPhone API parameters are totally different and they are NOT compatible with this Android API library! You MUST use a real Android APK when capturing requests!
+
+Once you have the endpoint and necessary parameters, how do you add them to this library? Easy, you can follow this example:
+
+```php
+    public function getAwesome(
+        array $userList)
+    {
+        return $this->ig->request('awesome/endpoint/')
+            ->setSignedPost(false)
+            ->addPost('_uuid', $this->ig->uuid)
+            ->addPost('user_ids', implode(',', $userList))
+            ->addPost('_csrftoken', $this->ig->client->getToken())
+            ->getResponse(new Response\AwesomeResponse());
+    }
+```
+
+In the example above you can see `('awesome/endpoint/')` which is the endpoint you captured. We are simulating a POST request, so you can add POST parameters easily by doing `->addPost('_uuid', $this->uuid)`.
+
+Which is basically:
+
+```php
+->addPost(key, value)
+```
+
+Where key is the name of the POST param, and value is whatever value the server requires for that parameter.
+
+Some of the requests are signed. This means there is a hash concatenated with the JSON. In order to make a signed request, we can enable or disable signing with the following line:
+
+```php
+->setSignedPost($isSigned)
+```
+
+`$isSigned` is boolean, so if you want a signed request, you simply set it to `true`.
+
+If the request is a GET request, you can add the GET query parameters like this (instead of using `addPost`):
+
+```php
+->addParam(key, value)
+```
+
+And finally, we always end with the `getResponse` function call, which will read the response and return an object with all of the server response values:
+
+```php
+->getResponse(new Response\AwesomeResponse());
+```
+
+Now you might be wondering how to create that response class? But there is nothing to worry about... it's very simple!
+
+Imagine that you have the following response:
+
+```json
+{"items": [{"user": {"is_verified": false, "has_anonymous_profile_picture": false, "is_private": false, "full_name": "awesome", "username": "awesome", "pk": "uid", "profile_pic_url": "profilepic"}, "large_urls": [], "caption": "", "thumbnail_urls": ["thumb1", "thumb2", "thumb3", "thumb4"]}], "status": "ok"}
+```
+
+You can use [http://jsoneditoronline.org](http://jsoneditoronline.org/) for a better visualization:
+
+<img src="https://s29.postimg.org/3xyopcbg7/insta_help.jpg" width="300">
+
+(Alternatively, if you're an advanced user, you can create an empty response-class (with no defined properties yet), and then use its `->printJson()` function to look at its contents in a beautifully readable way.)
+
+So your new `src/Response/AwesomeResponse.php` class should contain one `JSON_PROPERTY_MAP` property named `items`. Our magical [LazyJsonMapper](https://github.com/lazyjsonmapper/lazyjsonmapper) object mapping system needs a PHPdoc-style type-definition to tell us if the property is another class, a float, an int, a string, a string array, etc. By default, if you don't specify any type (if you set its value to `''`), it will treat the JSON value as whatever type PHP detected it as internally during JSON decoding (such as a string, int, float, bool, etc).
+
+In this scenario, your `src/Response/AwesomeResponse.php` file and its property definitions should look as follows, since we want to map `items` to an array of `Suggestion` objects:
+
+```php
+<?php
+
+namespace InstagramAPI\Response;
+
+use InstagramAPI\Response;
+
+class AwesomeResponse extends Response
+{
+    const JSON_PROPERTY_MAP = [
+        'items' => 'Model\Suggestion[]',
+    ];
+}
+```
+
+The `items` property will now expect an array of Suggestion model objects. And `src/Response/Model/Suggestion.php` should look like this:
+
+```php
+<?php
+
+namespace InstagramAPI\Response\Model;
+
+use InstagramAPI\AutoPropertyMapper;
+
+class Suggestion extends AutoPropertyMapper
+{
+    const JSON_PROPERTY_MAP = [
+        'media_infos'    => '',
+        'social_context' => '',
+        'algorithm'      => '',
+        'thumbnail_urls' => 'string[]',
+        'value'          => '',
+        'caption'        => '',
+        'user'           => 'User',
+        'large_urls'     => 'string[]',
+        'media_ids'      => '',
+        'icon'           => '',
+    ];
+}
+```
+
+Here in this `Suggestion` class you can see many variables that didn't appear in our example endpoint's response, but that's because many other requests _re-use_ the same object, and depending the request, their response contents may differ a bit. Also note that unlike the AwesomeResponse class, the actual Model objects (the files in in `src/Response/Model/`) _don't_ use the "Model\" prefix when referring to other model objects, since they are in the same namespace already.
+
+Also note that many of the properties above are defined as `''` (no type), which means "mixed/untyped". It simply means that the value is not forcibly converted to anything. That's how you should define most properties unless you have a specific reason to force anything to a specific type.
+
+It is also _extremely important_ that any properties relating to Media IDs, PKs, User PKs, etc, _must_ be declared as a `string`, otherwise they may be handled as a float/int which won't fit on 32-bit CPUs and will truncate the number, leading to the wrong data. Just look at all other Model objects that are already in this project, and be sure that any ID/PK fields in your own new Model object are properly tagged as `string` type too!
+
+Now you can test your new endpoint, in order to look at its response object:
+
+```
+$awesome = $i->getAwesome(['123']);
+$awesome->printJson(); // Look at the object data.
+$awesome->printPropertyDescriptions(); // Look at all defined properties.
+```
+
+And finally, how do you access the object's data? Via the magical [LazyJsonMapper](https://github.com/lazyjsonmapper/lazyjsonmapper), which your Response and Model objects inherit from! It automatically creates getters and setters for all properties, and has a million other features!
+
+```php
+$items = $awesome->getItems();
+$user = $items[0]->getUser();
+
+// LazyJsonMapper even lets you look at the JSON of specific sub-objects:
+$user->printJson();
+```
+
+Lastly, you may sometimes be implementing an endpoint which uses a nearly empty response with just the standard `status` and/or `message` (and `_messages`) fields, and no other fields. In that case, there's already a pre-made response which you should use: `GenericResponse`. Search the source code for that word and you'll find many endpoints where we use that basic response. Use it to easily add new endpoint implementations whenever there's no extra data to extract!
+
+We hope that you found this tutorial useful! :smile:

+Reciprocal Public License (RPL-1.5)
+
+Version 1.5, July 15, 2007
+
+Copyright (C) 2001-2007
+Technical Pursuit Inc.,
+All Rights Reserved.
+
+
+PREAMBLE
+
+The Reciprocal Public License (RPL) is based on the concept of reciprocity or,
+if you prefer, fairness.
+
+In short, this license grew out of a desire to close loopholes in previous open
+source licenses, loopholes that allowed parties to acquire open source software
+and derive financial benefit from it without having to release their
+improvements or derivatives to the community which enabled them. This occurred
+any time an entity did not release their application to a "third party".
+
+While there is a certain freedom in this model of licensing, it struck the
+authors of the RPL as being unfair to the open source community at large and to
+the original authors of the works in particular. After all, bug fixes,
+extensions, and meaningful and valuable derivatives were not consistently
+finding their way back into the community where they could fuel further, and
+faster, growth and expansion of the overall open source software base.
+
+While you should clearly read and understand the entire license, the essence of
+the RPL is found in two definitions: "Deploy" and "Required Components".
+
+Regarding deployment, under the RPL your changes, bug fixes, extensions, etc.
+must be made available to the open source community at large when you Deploy in
+any form -- either internally or to an outside party. Once you start running
+the software you have to start sharing the software.
+
+Further, under the RPL all components you author including schemas, scripts,
+source code, etc. -- regardless of whether they're compiled into a single
+binary or used as two halves of client/server application -- must be shared.
+You have to share the whole pie, not an isolated slice of it.
+
+In addition to these goals, the RPL was authored to meet the requirements of
+the Open Source Definition as maintained by the Open Source Initiative (OSI).
+
+The specific terms and conditions of the license are defined in the remainder
+of this document.
+
+

+Nothing in this License shall be interpreted to prohibit Licensor from
+licensing under different terms from this License any code that Licensor
+otherwise would have a right to license.
+
+5.1 You expressly acknowledge and agree that although Licensor and each
+Contributor grants the licenses to their respective portions of the Licensed
+Software set forth herein, no assurances are provided by Licensor or any
+Contributor that the Licensed Software does not infringe the patent or other
+intellectual property rights of any other entity. Licensor and each
+Contributor disclaim any liability to You for claims brought by any other
+entity based on infringement of intellectual property rights or otherwise. As
+a condition to exercising the rights and licenses granted hereunder, You
+hereby assume sole responsibility to secure any other intellectual property

+responsibility to acquire that license before distributing the Licensed
+Software.
+
+6.0 Your Obligations And Grants. In consideration of, and as an express
+condition to, the licenses granted to You under this License You hereby agree
+that any Modifications, Derivative Works, or Required Components (collectively
+Extensions) that You create or to which You contribute are governed by the
+terms of this License including, without limitation, Section 4. Any Extensions
+that You create or to which You contribute must be Deployed under the terms of
+this License or a future version of this License released under Section 7. You
+hereby grant to Licensor and all third parties a world-wide, non-exclusive,
+royalty-free license under those intellectual property rights You own or
+control to use, reproduce, display, perform, modify, create derivatives,
+sublicense, and distribute Licensed Software, in any form. Any Extensions You
+make and Deploy must have a distinct title so as to readily tell any
+subsequent user or Contributor that the Extensions are by You. You must
+include a copy of this License or directions on how to obtain a copy with
+every copy of the Extensions You distribute. You agree not to offer or impose
+any terms on any Source Code or executable version of the Licensed Software,
+or its Extensions that alter or restrict the applicable version of this
+License or the recipients' rights hereunder.
+
+6.1 Availability of Source Code. You must make available, under the terms of
+this License, the Source Code of any Extensions that You Deploy, via an
+Electronic Distribution Mechanism. The Source Code for any version that You
+Deploy must be made available within one (1) month of when you Deploy and must
+remain available for no less than twelve (12) months after the date You cease
+to Deploy. You are responsible for ensuring that the Source Code to each
+version You Deploy remains available even if the Electronic Distribution
+Mechanism is maintained by a third party. You may not charge a fee for any
+copy of the Source Code distributed under this Section in excess of Your
+actual cost of duplication and distribution of said copy.
+
+6.2 Description of Modifications. You must cause any Modifications that You
+create or to which You contribute to be documented in the Source Code, clearly
+describing the additions, changes or deletions You made. You must include a
+prominent statement that the Modifications are derived, directly or indirectly,
+from the Licensed Software and include the names of the Licensor and any
+Contributor to the Licensed Software in (i) the Source Code and (ii) in any
+notice displayed by the Licensed Software You distribute or in related
+documentation in which You describe the origin or ownership of the Licensed
+Software. You may not modify or delete any pre-existing copyright notices,
+change notices or License text in the Licensed Software without written
+permission of the respective Licensor or Contributor.
+
+6.3 Intellectual Property Matters.
+
+a. Third Party Claims. If You have knowledge that a license to a third party's
+intellectual property right is required to exercise the rights granted by this
+License, You must include a human-readable file with Your distribution that
+describes the claim and the party making the claim in sufficient detail that a
+recipient will know whom to contact.
+
+b. Contributor APIs. If Your Extensions include an application programming
+interface ("API") and You have knowledge of patent licenses that are
+reasonably necessary to implement that API, You must also include this
+information in a human-readable file supplied with Your distribution.
+
+c. Representations. You represent that, except as disclosed pursuant to 6.3(a)
+above, You believe that any Extensions You distribute are Your original
+creations and that You have sufficient rights to grant the rights conveyed by
+this License.
+
+6.4 Required Notices.
+
+a. License Text. You must duplicate this License or instructions on how to
+acquire a copy in any documentation You provide along with the Source Code of
+any Extensions You create or to which You contribute, wherever You describe
+recipients' rights relating to Licensed Software.
+
+b. License Notice. You must duplicate any notice contained in EXHIBIT A (the
+"License Notice") in each file of the Source Code of any copy You distribute
+of the Licensed Software and Your Extensions. If You create an Extension, You
+may add Your name as a Contributor to the Source Code and accompanying
+documentation along with a description of the contribution. If it is not
+possible to put the License Notice in a particular Source Code file due to its
+structure, then You must include such License Notice in a location where a
+user would be likely to look for such a notice.
+
+c. Source Code Availability. You must notify the software community of the
+availability of Source Code to Your Extensions within one (1) month of the date
+You initially Deploy and include in such notification a description of the
+Extensions, and instructions on how to acquire the Source Code. Should such
+instructions change you must notify the software community of revised
+instructions within one (1) month of the date of change. You must provide
+notification by posting to appropriate news groups, mailing lists, weblogs, or
+other sites where a publicly accessible search engine would reasonably be
+expected to index your post in relationship to queries regarding the Licensed
+Software and/or Your Extensions.
+
+d. User-Visible Attribution. You must duplicate any notice contained in
+EXHIBIT B (the "User-Visible Attribution Notice") in each user-visible display
+of the Licensed Software and Your Extensions which delineates copyright,
+ownership, or similar attribution information. If You create an Extension,
+You may add Your name as a Contributor, and add Your attribution notice, as an
+equally visible and functional element of any User-Visible Attribution Notice
+content. To ensure proper attribution, You must also include such User-Visible
+Attribution Notice in at least one location in the Software documentation
+where a user would be likely to look for such notice.
+
+6.5 Additional Terms. You may choose to offer, and charge a fee for, warranty,
+support, indemnity or liability obligations to one or more recipients of
+Licensed Software. However, You may do so only on Your own behalf, and not on
+behalf of the Licensor or any Contributor except as permitted under other
+agreements between you and Licensor or Contributor. You must make it clear that
+any such warranty, support, indemnity or liability obligation is offered by You
+alone, and You hereby agree to indemnify the Licensor and every Contributor for
+any liability plus attorney fees, costs, and related expenses due to any such
+action or claim incurred by the Licensor or such Contributor as a result of
+warranty, support, indemnity or liability terms You offer.
+
+6.6 Conflicts With Other Licenses. Where any portion of Your Extensions, by
+virtue of being Derivative Works of another product or similar circumstance,
+fall under the terms of another license, the terms of that license should be
+honored however You must also make Your Extensions available under this
+License. If the terms of this License continue to conflict with the terms of
+the other license you may write the Licensor for permission to resolve the
+conflict in a fashion that remains consistent with the intent of this License.
+Such permission will be granted at the sole discretion of the Licensor.
+
+7.0 Versions of This License. Licensor may publish from time to time revised
+versions of the License. Once Licensed Software has been published under a
+particular version of the License, You may always continue to use it under the
+terms of that version. You may also choose to use such Licensed Software under
+the terms of any subsequent version of the License published by Licensor. No
+one other than Licensor has the right to modify the terms applicable to
+Licensed Software created under this License.
+
+7.1 If You create or use a modified version of this License, which You may do
+only in order to apply it to software that is not already Licensed Software
+under this License, You must rename Your license so that it is not confusingly
+similar to this License, and must make it clear that Your license contains
+terms that differ from this License. In so naming Your license, You may not
+use any trademark of Licensor or of any Contributor. Should Your modifications
+to this License be limited to alteration of a) Section 13.8 solely to modify
+the legal Jurisdiction or Venue for disputes, b) EXHIBIT A solely to define
+License Notice text, or c) to EXHIBIT B solely to define a User-Visible
+Attribution Notice, You may continue to refer to Your License as the
+Reciprocal Public License or simply the RPL.
+

+
+12.0 Termination. This License and all rights granted hereunder will terminate
+immediately in the event of the circumstances described in Section 13.6 or if
+applicable law prohibits or restricts You from fully and or specifically
+complying with Sections 3, 4 and/or 6, or prevents the enforceability of any
+of those Sections, and You must immediately discontinue any use of Licensed
+Software.
+
+12.1 Automatic Termination Upon Breach. This License and the rights granted
+hereunder will terminate automatically if You fail to comply with the terms
+herein and fail to cure such breach within thirty (30) days of becoming aware
+of the breach. All sublicenses to the Licensed Software that are properly
+granted shall survive any termination of this License. Provisions that, by
+their nature, must remain in effect beyond the termination of this License,
+shall survive.
+
+12.2 Termination Upon Assertion of Patent Infringement. If You initiate
+litigation by asserting a patent infringement claim (excluding declaratory
+judgment actions) against Licensor or a Contributor (Licensor or Contributor
+against whom You file such an action is referred to herein as "Respondent")
+alleging that Licensed Software directly or indirectly infringes any patent,
+then any and all rights granted by such Respondent to You under Sections 3 or
+4 of this License shall terminate prospectively upon sixty (60) days notice
+from Respondent (the "Notice Period") unless within that Notice Period You
+either agree in writing (i) to pay Respondent a mutually agreeable reasonably
+royalty for Your past or future use of Licensed Software made by such
+Respondent, or (ii) withdraw Your litigation claim with respect to Licensed
+Software against such Respondent. If within said Notice Period a reasonable
+royalty and payment arrangement are not mutually agreed upon in writing by the
+parties or the litigation claim is not withdrawn, the rights granted by
+Licensor to You under Sections 3 and 4 automatically terminate at the
+expiration of said Notice Period.
+
+12.3 Reasonable Value of This License. If You assert a patent infringement
+claim against Respondent alleging that Licensed Software directly or
+indirectly infringes any patent where such claim is resolved (such as by
+license or settlement) prior to the initiation of patent infringement
+litigation, then the reasonable value of the licenses granted by said
+Respondent under Sections 3 and 4 shall be taken into account in determining
+the amount or value of any payment or license.
+
+12.4 No Retroactive Effect of Termination. In the event of termination under
+this Section all end user license agreements (excluding licenses to
+distributors and resellers) that have been validly granted by You or any
+distributor hereunder prior to termination shall survive termination.
+
+13.0 Miscellaneous.
+
+13.1 U.S. Government End Users. The Licensed Software is a "commercial item,"
+as that term is defined in 48 C.F.R. 2.101 (Oct. 1995), consisting of
+"commercial computer software" and "commercial computer software
+documentation," as such terms are used in 48 C.F.R. 12.212 (Sept. 1995).
+Consistent with 48 C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4
+(June 1995), all U.S. Government End Users acquire Licensed Software with only
+those rights set forth herein.
+
+13.2 Relationship of Parties. This License will not be construed as creating
+an agency, partnership, joint venture, or any other form of legal association
+between or among You, Licensor, or any Contributor, and You will not represent
+to the contrary, whether expressly, by implication, appearance, or otherwise.
+
+13.3 Independent Development. Nothing in this License will impair Licensor's
+right to acquire, license, develop, subcontract, market, or distribute
+technology or products that perform the same or similar functions as, or
+otherwise compete with, Extensions that You may develop, produce, market, or
+distribute.
+
+13.4 Consent To Breach Not Waiver. Failure by Licensor or Contributor to
+enforce any provision of this License will not be deemed a waiver of future enforcement
+of that or any other provision.
+
+13.5 Severability. This License represents the complete agreement concerning
+the subject matter hereof. If any provision of this License is held to be
+unenforceable, such provision shall be reformed only to the extent necessary
+to make it enforceable.
+
+13.6 Inability to Comply Due to Statute or Regulation. If it is impossible for
+You to comply with any of the terms of this License with respect to some or
+all of the Licensed Software due to statute, judicial order, or regulation,
+then You cannot use, modify, or distribute the software.
+
+13.7 Export Restrictions. You may be restricted with respect to downloading or
+otherwise acquiring, exporting, or reexporting the Licensed Software or any
+underlying information or technology by United States and other applicable
+laws and regulations. By downloading or by otherwise obtaining the Licensed
+Software, You are agreeing to be responsible for compliance with all
+applicable laws and regulations.
+
+13.8 Arbitration, Jurisdiction & Venue. This License shall be governed by
+Colorado law provisions (except to the extent applicable law, if any, provides
+otherwise), excluding its conflict-of-law provisions. You expressly agree that
+any dispute relating to this License shall be submitted to binding arbitration
+under the rules then prevailing of the American Arbitration Association. You
+further agree that Adams County, Colorado USA is proper venue and grant such
+arbitration proceeding jurisdiction as may be appropriate for purposes of
+resolving any dispute under this License. Judgement upon any award made in
+arbitration may be entered and enforced in any court of competent
+jurisdiction. The arbitrator shall award attorney's fees and costs of
+arbitration to the prevailing party. Should either party find it necessary to
+enforce its arbitration award or seek specific performance of such award in a
+civil court of competent jurisdiction, the prevailing party shall be entitled
+to reasonable attorney's fees and costs. The application of the United Nations
+Convention on Contracts for the International Sale of Goods is expressly
+excluded. You and Licensor expressly waive any rights to a jury trial in any
+litigation concerning Licensed Software or this License. Any law or regulation
+that provides that the language of a contract shall be construed against the
+drafter shall not apply to this License.
+
+13.9 Entire Agreement. This License constitutes the entire agreement between
+the parties with respect to the subject matter hereof.

+----------
+## Installation
+
+### Dependencies
+
+Install/enable the required php extensions and dependencies. You can learn how to do so [here](https://github.com/mgp25/Instagram-API/wiki/Dependencies).
+
+### Install this library
+We use composer to distribute our code effectively and easily. If you do not already have composer installed, you can download and install it here [here](https://getcomposer.org/download/).
+
+Once you have composer installed, you can do the following:
+```sh
+composer require mgp25/instagram-php
+```
+
+```php
+require __DIR__.'/../vendor/autoload.php';
+
+$ig = new \InstagramAPI\Instagram();
+```
+
+If you want to test new and possibly unstable code that is in the master branch, and which hasn't yet been released, then you can do the following (at your own risk):
+
+```sh
+composer require mgp25/instagram-php dev-master
+```
+
+#### _Warning about moving data to a different server_
+
+_Composer checks your system's capabilities and selects libraries based on your **current** machine (where you are running the `composer` command). So if you run Composer on machine `A` to install this library, it will check machine `A`'s capabilities and will install libraries appropriate for that machine (such as installing the PHP 7+ versions of various libraries). If you then move your whole installation to machine `B` instead, it **will not work** unless machine `B` has the **exact** same capabilities (same or higher PHP version and PHP extensions)! Therefore, you should **always** run the Composer-command on your intended target machine instead of your local machine._

+## How do I contribute
+
+If you would like to contribute to this project, please feel free to submit a pull request.
+
+Before you do, take a look at the [contributing guide](https://github.com/mgp25/Instagram-API/blob/master/CONTRIBUTING.md).
+
+## Why did I make this API?
+
+After legal measures, Facebook, WhatsApp and Instagram blocked my accounts.
+In order to use Instagram on my phone I needed a new phone, as they banned my UDID, so that is basically why I made this API.
+
+### What is Instagram?
+According to [the company](https://instagram.com/about/faq/):
+
+> "Instagram is a fun and quirky way to share your life with friends through a series of pictures. Snap a photo with your mobile phone, then choose a filter to transform the image into a memory to keep around forever. We're building Instagram to allow you to experience moments in your friends' lives through pictures as they happen. We imagine a world more connected through photos."
+
+# License
+
+In order help ensure fairness and sharing, this library is dual-licensed. Be
+aware that _all_ usage, unless otherwise specified, is under the **RPL-1.5**
+license!
+
+- Reciprocal Public License 1.5 (RPL-1.5): https://opensource.org/licenses/RPL-1.5
+
+You should read the _entire_ license; especially the `PREAMBLE` at the
+beginning. In short, the word `reciprocal` means "giving something back in
+return for what you are getting". It is _**not** a freeware license_. This
+license _requires_ that you open-source _all_ of your own source code for _any_
+project which uses this library! Creating and maintaining this library is
+endless hard work for us. That's why there is _one_ simple requirement for you:
+Give _something_ back to the world. Whether that's code _or_ financial support
+for this project is entirely up to you, but _nothing else_ grants you _any_
+right to use this library.
+
+Furthermore, the library is _also_ available _to certain entities_ under a
+modified version of the RPL-1.5, which has been modified to allow you to use the
+library _without_ open-sourcing your own project. The modified license
+(see [LICENSE_PREMIUM](https://github.com/mgp25/Instagram-API/blob/master/LICENSE_PREMIUM))
+is granted to certain entities, at _our_ discretion, and for a _limited_ period
+of time (unless otherwise agreed), pursuant to our terms. Currently, we are
+granting this license to all
+"[premium subscribers](https://github.com/mgp25/Instagram-API/issues/2655)" for
+the duration of their subscriptions. You can become a premium subscriber by
+either contributing substantial amounts of high-quality code, or by subscribing
+for a fee. This licensing ensures fairness and stimulates the continued growth
+of this library through both code contributions and the financial support it
+needs.
+
+You are not required to accept this License since you have not signed it,
+however _nothing else_ grants you permission to _use_, copy, distribute, modify,
+or create derivatives of either the Software (this library) or any Extensions
+created by a Contributor. These actions are prohibited by law if you do not
+accept this License. Therefore, by performing any of these actions You indicate
+Your acceptance of this License and Your agreement to be bound by all its terms
+and conditions. IF YOU DO NOT AGREE WITH ALL THE TERMS AND CONDITIONS OF THIS
+LICENSE DO NOT USE, MODIFY, CREATE DERIVATIVES, OR DISTRIBUTE THE SOFTWARE. IF
+IT IS IMPOSSIBLE FOR YOU TO COMPLY WITH ALL THE TERMS AND CONDITIONS OF THIS
+LICENSE THEN YOU CAN NOT USE, MODIFY, CREATE DERIVATIVES, OR DISTRIBUTE THE
+SOFTWARE.
+
+# Terms and conditions
+
+- You will NOT use this API for marketing purposes (spam, botting, harassment, massive bulk messaging...).
+- We do NOT give support to anyone who wants to use this API to send spam or commit other crimes.
+- We reserve the right to block any user of this repository that does not meet these conditions.
+
+## Legal
+
+This code is in no way affiliated with, authorized, maintained, sponsored or endorsed by Instagram or any of its affiliates or subsidiaries. This is an independent and unofficial API. Use at your own risk.

+ * This example demonstrates how to use and customize user settings storages.
+ *
+ * By default, if you don't give us any custom configuration, we will always use
+ * the "File" storage backend, which keeps all data in regular files on disk. It
+ * is a rock-solid backend and will be very good for most people.
+ *
+ * However, other people may want to use something more advanced, such as one of
+ * the other built-in storage backends ("MySQL", "SQLite" and "Memcached"). Or
+ * perhaps you'd even like to build your own backend (doing so is very easy).
+ */
+
+echo "You are not supposed to execute this script. Read it in a text editor to see various storage methods.\n";
+exit;
+
+// These points will give you a basic overview of the process. But you should
+// read the code in src/Settings/ for the full details. It is well documented.
+
+// 1. Choosing a built-in storage backend (one of "file", "mysql", "sqlite" or
+// "memcached"), and using the automatic, default settings for that backend:
+$ig = new \InstagramAPI\Instagram($debug, $truncatedDebug, [
+    'storage' => 'mysql',
+]);
+
+// 2. You can read src/Settings/Factory.php for valid settings for each backend.
+// Here's an example of how to change the default storage location for "file":
+$ig = new \InstagramAPI\Instagram($debug, $truncatedDebug, [
+    'storage'    => 'file',
+    'basefolder' => 'some/path/',
+]);
+
+// 3. And here's an example of how to change the default database filename and
+// the default database table name for the "sqlite" backend:
+$ig = new \InstagramAPI\Instagram($debug, $truncatedDebug, [
+    'storage'     => 'sqlite',
+    'dbfilename'  => 'some/path/foo.db',
+    'dbtablename' => 'mysettings',
+]);
+
+// 4. If you read src/Settings/Factory.php, you'll notice that you can choose
+// the storage backends and most of their parameters via the command line or
+// environment variables instead. For example: "SETTINGS_STORAGE=mysql php
+// yourscript.php" would set the "storage" parameter via the environment, and
+// typing "php yourscript.php --settings_storage=mysql" would set it via the
+// command line. The command-line arguments have the highest precedence, then
+// the environment variables, and lastly the code within your script. This
+// precedence order is so that you can easily override your script's code to
+// test other backends or change their parameters without modifying your code.
+
+// 5. Very advanced users can look in src/Settings/StorageHandler.php to read
+// about hasUser(), moveUser() and deleteUser(). Three very, VERY DANGEROUS
+// commands which let you rename or delete account settings in your storage.
+// Carefully read through their descriptions and use them wisely. If you're sure
+// that you dare to use them, then you can access them via $ig->settings->...
+
+// 6. Yet another super advanced topic is the ability to copy data between
+// backends. For example if you want to move all of your data from a File
+// backend to a database, or vice versa. That kind of action is not supported
+// natively by us, but you CAN do it by directly interfacing with the storages!
+
+// First, you MUST manually build a list of all users you want to migrate.
+// You can either hardcode this list. Or get it via something like a directory
+// scan (to look at existing folders in a File backend storage path), or a
+// database query to get all "username" values from the old database. If you're
+// using a database, you will have to connect to it manually and query it
+// yourself! There's no way to do it automatically! Just build this array any
+// way you want to do it!
+$migrateUsers = [
+    'someuser',
+    'another.user',
+    'very_awesome_user123',
+];
+
+// Secondly, you must connect to your old and new storages. These are just
+// example values. The array format is the exact same as what's given to the
+// `Instagram()` constructor! And if you give an empty array, you'll use the
+// same default File backend that the main class uses! So if you want to migrate
+// from that, you should just set oldStorage to `createHandler([])`!
+$oldStorage = \InstagramAPI\Settings\Factory::createHandler([
+    'storage'     => 'sqlite',
+    'dbfilename'  => 'app/instagram.sqlite',
+    'dbtablename' => 'instagram_sessions',
+]);
+$newStorage = \InstagramAPI\Settings\Factory::createHandler([
+    'storage'     => 'file',
+    'basefolder'  => 'some/path/',
+]);
+
+// Now just run the migration process. This will copy all cookies and settings
+// from the old storage to the new storage, for all of the "migrateUsers".
+foreach ($migrateUsers as $user) {
+    if (!$oldStorage->hasUser($user)) {
+        die("Unable to migrate '{$user}' from old storage (user doesn't exist).\n");
+    }
+
+    echo "Migrating '{$user}'.\n";
+
+    $oldStorage->setActiveUser($user);
+    $newStorage->setActiveUser($user);
+
+    $newStorage->setCookies((string) $oldStorage->getCookies());
+    foreach (\InstagramAPI\Settings\StorageHandler::PERSISTENT_KEYS as $key) {
+        $newStorage->set($key, (string) $oldStorage->get($key));
+    }
+}
+
+// 7. Lastly... if you want to implement your own completely CUSTOM STORAGE,
+// then you simply have to do one thing: Implement the StorageInterface class
+// interface. But be very sure to STRICTLY follow ALL rules for storage backends
+// described in that interface's docs, otherwise your custom backend WON'T work.
+//
+// See the overview in src/Settings/StorageInterface.php, and then read through
+// the various built-in storage backends in src/Settings/Storage/ to see perfect
+// implementations that completely follow the required interface specification.
+//
+// Also note that PDO-based backends should be derived from our "PDOStorage"
+// storage sub-component, so that the logic is perfectly implemented and not
+// duplicated. That's exactly how our "sqlite" and "mysql" PDO backends work!
+//
+// To use your custom storage backend, you would simply create your own class
+// similar to the built-in backends. But do NOT put your own class in our
+// src/Settings/Storage/ folder. Store your class inside your own project.
+//
+// Then simply provide your custom storage class instance as the storage class:
+$ig = new \InstagramAPI\Instagram($debug, $truncatedDebug, [
+    'storage' => 'custom',
+    'class'   => new MyCustomStorage(), // Whatever you've named your class.
+]);
+
+// That's it! This should get you started on your journey. :-)
+
+// And please think about contributing your WELL-WRITTEN storage backends to
+// this project! If you had a reason to write your own, then there's probably
+// someone else out there with the same need. Remember to SHARE with the open
+// source community! ;-)

+/**
+ * Internal list of verified Android devices.
+ *
+ * @author SteveJobzniak (https://github.com/SteveJobzniak)
+ *
+ * This is a list of popular, modern Android phones, all VERIFIED to support
+ * receiving the max-resolution videos from Instagram's API replies. This list
+ * has to be hand-crafted, because bad devices only receive low-resolution
+ * videos! Instagram's API looks at device MODEL when deciding to deliver HD.
+ *
+ * The goal with this list is to have a list of ~10 modern phones which we only
+ * have to refresh every few years, as they slip away into obscurity.
+ *
+ * Here are the rules for building the list:
+ *
+ * - Find a top-list of the best Android phones for [current year].
+ * - Only select devices with super high resolution screens (at least 1080p+).
+ * - Find the model at https://www.handsetdetection.com/properties/devices.
+ * - Some phones have tons of sub-models. Find the phone on Amazon and look at
+ *   the details to find sub-model identifier for the most popular US variant!
+ * - Research the model's popularity. For example, NEVER include a Samsung phone
+ *   with an "X" suffix (such as SM-G935X). Those are STORE DEMO units.
+ * - Check if they've recorded any Instagram user agent. If there are multiple
+ *   agents for Instagram, compare them all carefully and pick the latest.
+ * - Look closely to make sure the string wasn't truncated or modified on their
+ *   site. I've seen phones lacking the locale and final parenthesis, for
+ *   example. Or strings that are all-lowercase. DO NOT USE THOSE!
+ * - Verify the device details by doing a Google search for the model identifier
+ *   you found in the user-agent, to verify all specs match the real device.
+ * - Enter good models below in the same format as the other devices. Triple and
+ *   quadruple check that it is 100% CORRECT for that device.
+ * - Always enter the EXACT Android version that the user agent was seen with on
+ *   the website above, which is usually the OS version the phone released with.
+ * - The Android version is the first part of the agent, such as "23/6.0.1".
+ *
+ * Here's an example string:
+ * "Instagram 10.9.0 Android (23/6.0.1; 480dpi; 1080x1776; LENOVO/Lenovo; Lenovo P2a42; P2a42; qcom; fr_FR)".
+ *
+ * The format is made via the android.os.Build library:
+ * "Instagram %s Android (%s/%s; %s; %s; %s/%s; %s; %s; %s)
+ * 1. Instagram VERSION.
+ * 2. Android API VERSION (Build$VERSION.SDK_INT)
+ * 3. Android VERSION (Build$VERSION.RELEASE)
+ * 4. DPI.
+ * 5. Display Resolution.
+ * 6. MANUFACTURER.
+ * 7 (optional). BRAND (this "/"-portion with a brand doesn't always exist).
+ * 8. MODEL.
+ * 9. DEVICE.
+ * 10. CPU (Build.HARDWARE)
+ * 11. Language (Build.LOCALE).
+ *
+ * We only want the part within parenthesis, and we ignore the locale.
+ *
+ * That gives us the following string:
+ * "23/6.0.1; 480dpi; 1080x1776; LENOVO/Lenovo; Lenovo P2a42; P2a42; qcom".
+ *
+ * However, note that the device above isn't at least 1920x1080. Don't use it.
+ *
+ *
+ * When you have a "possibly good" agent, you must finally TEST IT: Use the
+ * "devtools/checkDevices.php" developer script to check your agent and verify
+ * that Instagram detects it as a high-resolution device and gives it HD videos!
+ *
+ *
+ * LASTLY, YOU MUST UNDERSTAND THE FOLLOWING: THE DEVICE LIST BELOW IS MEANT TO
+ * BE A "SNAPSHOT" OF DEVICES AND THEIR ANDROID VERSIONS AT THAT MOMENT IN TIME.
+ * WE ARE *ONLY* SUPPOSED TO *ADD* NEW DEVICES TO IT OR COMPLETELY *DELETE* OLD
+ * DEVICES. DO *NOT* "EDIT" THE LIST TO TRY TO "IMPROVE" OR "UPDATE" ANDROID
+ * VERSIONS OR *ANYTHING* ELSE ABOUT AN EXISTING DEVICE. EDITING EVEN A *SINGLE*
+ * BYTE WILL CAUSE *ALL* USERS OF THAT DEVICE TO BE LOGGED OUT AND *RE-ASSIGNED*
+ * TO A BRAND NEW PHONE HARDWARE FINGERPRINT AND A DIFFERENT RANDOM DEVICE. THAT
+ * BEHAVIOR IS INTENTIONAL AND *BY DESIGN*. IT ALLOWS US TO SAFELY BLACKLIST BAD
+ * DEVICES AND IT DISCOURAGES DUMB, FRIVOLOUS "UPGRADES", THUS ENSURING THAT WE
+ * *ONLY* IDENTIFY OUR DEVICES WITH THE ACTUAL *ANDROID* VERSION THEY *SHIPPED*
+ * WITH, WHICH IS THE SAFEST WAY TO IDENTIFY OUR VIRTUAL DEVICES. MOST REAL
+ * USERS DON'T UPGRADE ANDROID OS BEYOND WHAT THE PHONE ORIGINALLY SHIPPED WITH.
+ *
+ *
+ * THIS DEVICE LIST IS CRITICAL TO THE OPERATION OF THE API. DO NOT CONTRIBUTE
+ * TO THIS LIST IF YOU DON'T UNDERSTAND *ALL* INSTRUCTIONS ABOVE. PERFECTLY. ALL
+ * CONTRIBUTIONS MUST INCLUDE THE RELEASE DATE, HANDSETDETECTION AND A LINK TO A
+ * PAGE (SUCH AS AMAZON) FOR THAT EXACT MODEL SPECIFIER, AS SEEN BELOW, SO THAT
+ * WE CAN VALIDATE ALL AGENTS TO SEE THAT YOU AREN'T ADDING AN INCORRECTLY
+ * WRITTEN OR UNPOPULAR DEVICE AGENT WHICH WILL GET US BANNED BY INSTAGRAM!

+     *
+     * - "horCropFocus" (int): Crop focus position (-50 .. 50) when cropping
+     *   horizontally (reducing width). Uses intelligent guess if not set.
+     *
+     * - "verCropFocus" (int): Crop focus position (-50 .. 50) when cropping
+     *   vertically (reducing height). Uses intelligent guess if not set.
+     *
+     * - "minAspectRatio" (float): Minimum allowed aspect ratio. Uses
+     *   auto-selected class constants (with the correct, legal Instagram
+     *   aspect ratio limits for your chosen target feed) if not set.
+     *
+     * - "maxAspectRatio" (float): Maximum allowed aspect ratio. Uses
+     *   auto-selected class constants (with the correct, legal Instagram
+     *   aspect ratio limits for your chosen target feed) if not set.
+     *
+     * - "forceAspectRatio" (float|int): Tell the media processor to enforce a
+     *   specific aspect ratio target. This custom value MUST be within the
+     *   "minAspectRatio" to "maxAspectRatio" range! NOTE: When your goal is to
+     *   generate a custom media aspect ratio, you should normally ONLY specify
+     *   THIS parameter and should NEVER tamper with the min/max aspect ratio
+     *   limits! Because when you're specifying a custom forced ratio here, we
+     *   WILL ALWAYS verify/process the media as-necessary to fit your desired
+     *   ratio (EVEN if the input media was "already valid" within the overall,
+     *   larger legal min/max ratio ranges). ALSO NOTE: We WON'T process input
+     *   media when it's already VERY close to the desired target ratio. The
+     *   ONLY custom aspect ratio value that is 100% guaranteed to be FULLY
+     *   ENFORCED is `1.0` (square). If you specify ANY other ratio, we will
+     *   accept a VERY SMALL deviation when the media is already almost exactly
+     *   at the desired ratio. This is done to prevent pointless "impossible
+     *   processing", since achieving EXACT non-`1.0` ratios is almost always
+     *   IMPOSSIBLE, so it's not worth trying with media that's already very
+     *   close. The reason why non-`1.0` ratios are impossibly hard to hit in
+     *   MOST cases, is because pixels cannot be subdivided into smaller
+     *   fractions than "1 whole pixel", so in most cases when we ask for
+     *   something like `1.25385` ratio and we have an input file such as
+     *   `640x512` (`1.25` ratio), it is PHYSICALLY IMPOSSIBLE to achieve a
+     *   `1.25385` ratio with that input and we could AT BEST reach a tiny
+     *   fraction away from that target; such as `641x512` (`1.251953125`
+     *   ratio), `639x512` (`1.248046875` ratio), `640x513` (`1.247563353`
+     *   ratio) or `640x511` (`1.252446184` ratio). So whether you CAN hit your
+     *   EXACT desired non-`1.0` ratio or NOT depends 100% on your input file's
+     *   resolution! That's why we passthrough files that are already super
+     *   close to the desired ratio. Either way, such a tiny difference in
+     *   aspect ratio won't be visible to the eye, so if you are using this
+     *   "target ratio" feature for creating Instagram albums where all media
+     *   has the same aspect ratio, the final result WILL still look perfect.
+     *
+     * - "useRecommendedRatio" (bool): Whether to use the recommended aspect
+     *   ratio for your specific media type and target feed (such as using an
+     *   appropriate `9:16` portrait widescreen for stories). Some targets use
+     *   the recommended ratio by default, and others disable this by default.
+     *   Therefore, you do NOT need to set this option manually unless you have
+     *   a VERY special reason to do so! NOTE: This will ALWAYS be set to
+     *   `FALSE` if you're using the "forceAspectRatio" parameter!
+     *
+     * - "allowNewAspectDeviation" (bool): Whether to allow the new, final
+     *   aspect ratio (during processing) to deviate slightly from the MIN/MAX
+     *   limits. By setting this option to `TRUE`, you will tell our processing
+     *   to allow "slightly too high/slightly too low" final aspect ratios
+     *   (instead of throwing an exception) and to still permit the final
+     *   "closest-possible canvas" we've calculated anyway. You should NEVER
+     *   need to use this feature, but if you have manually configured extremely
+     *   narrow min/max aspect ratio parameters (which your input media CANNOT
+     *   be tweaked to fit perfectly within) then you MAY want to enable this.
+     *
+     * - "bgColor" (array) - Array with 3 color components `[R, G, B]`
+     *   (0-255/0x00-0xFF) for the background. Uses white if not set.

+     * - "blurredBorder" (bool) - Whether to use the media as a blurred border.
+     *   False if not set.
+     *
+     * - "operation" (int) - Operation to perform on the media (CROP or EXPAND).
+     *   Uses `self::CROP` if not set.
+     *
+     * - "tmpPath" (string) - Path to temp directory. Uses system temp location
+     *   or the class-default (`self::$defaultTmpPath`) if not set.
+     *
+     * - "debug" (bool) - Whether to output debugging info during calculation

+         * Everything is finely tuned to create 100% accurate, pixel-perfect
+         * resizes. A SINGLE PIXEL ERROR in your calculations WILL lead to it
+         * sometimes outputting illegally formatted files that will be rejected
+         * by Instagram. We know this, because we have SEEN IT HAPPEN while we
+         * tweaked and tweaked and tweaked to balance everything perfectly!
+         *
+         * Unfortunately, this file also seems to attract a lot of beginners.
+         * Maybe because a "media processor" seems "fun and easy". But that
+         * would be an incorrect guess. It's the most serious algorithm in the
+         * whole project. If you break it, *YOU* break people's uploads.
+         *
+         * We have had many random, new contributors just jumping in and adding
+         * zero-effort code everywhere in here, and breaking the whole balance,
+         * and then opening pull requests. We have rejected EVERY single one of
+         * those pull requests because they were totally unusable and unsafe.
+         *
+         * We will not accept such pull requests. Ever.
+         *
+         * This warning is here to save your time, and ours.
+         *
+         * If you are interested in helping out with the media algorithms, then
+         * that's GREAT! But in that case we require that you fully read through
+         * the algorithms below and all of its comments about 50 times over a
+         * 3-4 day period - until you understand every single step perfectly.
+         * The comments will help make it clearer the more you read...

+         *                                               ...and make an effort.

+/**
+ * Data Storage Interface.
+ *
+ * These methods must be implemented by all storage backends. All of their input
+ * and output validation is already done by the owning Settings class, so that
+ * backends can focus on dealing with basic, fully verified data (instead of
+ * writing and maintaining a bunch of boilerplate code to verify parameters).
+ *
+ * All functions in this file are listed in roughly the sequence they're called
+ * during normal operation. You can completely trust that they are called in a
+ * sane order and that you do not need to validate the call order.
+ *
+ * -- HOW TO STORE DATA: --
+ *
+ * The ONLY datatype we use for settings is STRINGS. You absolutely MUST store
+ * ALL data as strings. Do NOT attempt any "fancy" formats such as "database INT
+ * columns", because we will OFTEN be storing empty strings in all fields. Your
+ * storage backends MUST use STRING storage and MUST allow EMPTY strings.
+ *
+ * Data length varies, but it's a VERY bad idea for you to cap the length. We
+ * may need to store very long data someday. For example, the cookie data that
+ * we already store is usually around 2000 characters long.
+ *
+ * Furthermore, do NOT make ANY assumptions about what settings-"keys/columns"
+ * we will be storing. There is a list in StorageHandler::PERSISTENT_KEYS, but
+ * it will DEFINITELY change several times in the future. If you hardcode those
+ * columns, you will be in trouble in the future. Therefore, the absolute BEST
+ * encoding method is to use a SINGLE file/database column for the settings and
+ * to JSON-encode everything. And to use a SINGLE file/database column for the
+ * cookies and simply store our raw cookie string as-provided.
+ *
+ * -- MAJOR WARNING: --
+ *
+ * Backend developers are NOT allowed to violate ANY aspect of this interface
+ * specification. ANY exceptions thrown MUST be of the EXACT types listed, and
+ * ALL return values MUST be of the EXACT types listed. This means that YOU will
+ * have to handle ALL exceptions thrown by your particular backend solution, and
+ * re-wrapping them as the required exceptions if necessary. Otherwise you WILL
+ * BREAK all user applications that use your terrible Storage implementation.
+ *
+ * Just look at our existing Storage implementations to see correct code.

+<h1>Instagram-API Warning!</h1>
+<h2>Can I run this library via a website?</h2>
+<p>No. Don't do it. You cannot <em>safely</em> use this <em><strong>or any other</strong> 3rd party Instagram libraries</em> directly via a website!</p>
+<p>This library (and <em>all other</em> 3rd party reverse engineered Instagram libraries), is made for command line usage in a terminal by running the script like a program (such as <code>php yourscript.php</code>). We do <strong>not</strong> recommend running this library via a web browser! Because browsers will terminate the PHP process as soon as the user closes their connection to the page (closes the tab, or presses "Stop loading page"), which means that your script can terminate at any moment. This library is not a webpage! It is an Instagram for Android application emulator. It emulates an <strong>application</strong>. Not a webpage. You cannot just randomly kill this library in the middle of work! (You might kill it while it's writing to disk or calling some important APIs!)</p>
+<p>And furthermore, if it's used on a webpage then it must waste time logging in to Instagram every time the user refreshes the webpage, since each page load would start a new script (meaning "a new Instagram app emulator") from scratch. And there are also massive risks about concurrent access from multiple web requests to a single user account which can corrupt your settings-storage or cookies. So we really, <em>really</em> do not recommend running this library via a browser! It's a <em>very</em> bad idea!</p>
+<p>Instead, you should run your Instagram app emulator script as a permanent 24/7 process, and make it dump data to a database which your regular website reads from, or make some kind of permanent localhost daemon that can listen locally on the server and receive queries on a port (localhost queries from the main website's scripts), and then performing those queries via the API and responding to the website script with something like JSON or with serialized <code>src/Response/</code> objects, which the website script then transforms for final display to the user.</p>
+<p>You must also be sure that your permanent process periodically calls <code>login()</code> inside your 24/7 PHP process, to emulate the Instagram for Android application being closed/opened and refreshing itself (like a real user would do). Otherwise it will soon get banned or silently limited as a "detected bot" by Instagram due to never calling login. Preferably use the same refresh ranges we use by default, so that you refresh <code>login()</code> within a random range between every 30 minutes, or at max every 6 hours.</p>
+<p>So, to recap: Make your "Instagram application" part a permanent process, and then make your webpage interact with that permanent process or an intermediary database in some way. That's the <em>proper</em> architecture system if you want to use this library online! Imagine it like your website talking to a phone and telling its permanently running Instagram app to do things. <em>That's</em> the proper design and that's how you have to think about things.</p>
+<p>Never forget this fact: This library (and <em>all</em> other 3rd party libraries) is an Android application emulator. It is not a website and will <em>never</em> be able to become a website (because the Android application is not a website!). Therefore, we will <em>never</em> give support to anyone who decides to use the library directly inside a webpage. If you do that, it's <em>at your own risk</em>! It is a really terrible and unsupported idea!</p>

+# Changelog
+
+All notable changes to this project will be documented in this file, in reverse chronological order by release.
+
+## 1.0.1 - 2016-08-06
+
+### Added
+
+- Nothing.
+
+### Deprecated
+
+- Nothing.
+
+### Removed
+
+- Nothing.
+
+### Fixed
+
+- Updated all `@return self` annotation references in interfaces to use
+  `@return static`, which more closelly follows the semantics of the
+  specification.
+- Updated the `MessageInterface::getHeaders()` return annotation to use the
+  value `string[][]`, indicating the format is a nested array of strings.
+- Updated the `@link` annotation for `RequestInterface::withRequestTarget()`
+  to point to the correct section of RFC 7230.
+- Updated the `ServerRequestInterface::withUploadedFiles()` parameter annotation
+  to add the parameter name (`$uploadedFiles`).
+- Updated a `@throws` annotation for the `UploadedFileInterface::moveTo()`
+  method to correctly reference the method parameter (it was referencing an
+  incorrect parameter name previously).
+
+## 1.0.0 - 2016-05-18
+
+Initial stable release; reflects accepted PSR-7 specification.

+PSR Http Message
+================
+
+This repository holds all interfaces/classes/traits related to
+[PSR-7](http://www.php-fig.org/psr/psr-7/).
+
+Note that this is not a HTTP message implementation of its own. It is merely an
+interface that describes a HTTP message. See the specification for more details.
+
+Usage
+-----
+
+We'll certainly need some stuff in here.

+PSR Log
+=======
+
+This repository holds all interfaces/classes/traits related to
+[PSR-3](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md).
+
+Note that this is not a logger of its own. It is merely an interface that
+describes a logger. See the specification for more details.
+
+Installation
+------------
+
+```bash
+composer require psr/log
+```
+
+Usage
+-----
+
+If you need a logger, you can use the interface like this:
+
+```php
+<?php
+
+use Psr\Log\LoggerInterface;
+
+class Foo
+{
+    private $logger;
+
+    public function __construct(LoggerInterface $logger = null)
+    {
+        $this->logger = $logger;
+    }
+
+    public function doSomething()
+    {
+        if ($this->logger) {
+            $this->logger->info('Doing work');
+        }
+
+        // do something useful
+    }
+}
+```
+
+You can then pick one of the implementations of the interface to get a logger.
+
+If you want to implement the interface, you can require this package and
+implement `Psr\Log\LoggerInterface` in your code. Please read the
+[specification text](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md)
+for details.

+
+*   Documentation for TTL precision with millisecond accuracy or below and
+    use high-resolution timer for cache TTL on PHP 7.3+.
+    (#35 and #38 by @clue)
+
+*   Improve API documentation and allow legacy HHVM to fail in Travis CI config.
+    (#34 and #36 by @clue)
+
+*   Prefix all global functions calls with \ to skip the look up and resolve process and go straight to the global function.
+    (#31 by @WyriHaximus)
+
+## 0.5.0 (2018-06-25)

+# Cache
+
+[![Build Status](https://travis-ci.org/reactphp/cache.svg?branch=master)](https://travis-ci.org/reactphp/cache)
+
+Async, [Promise](https://github.com/reactphp/promise)-based cache interface
+for [ReactPHP](https://reactphp.org/).
+
+The cache component provides a
+[Promise](https://github.com/reactphp/promise)-based
+[`CacheInterface`](#cacheinterface) and an in-memory [`ArrayCache`](#arraycache)
+implementation of that.
+This allows consumers to type hint against the interface and third parties to
+provide alternate implementations.
+This project is heavily inspired by
+[PSR-16: Common Interface for Caching Libraries](https://www.php-fig.org/psr/psr-16/),
+but uses an interface more suited for async, non-blocking applications.

+
+## Usage
+
+### CacheInterface
+
+The `CacheInterface` describes the main interface of this component.
+This allows consumers to type hint against the interface and third parties to
+provide alternate implementations.
+
+#### get()
+
+The `get(string $key, mixed $default = null): PromiseInterface<mixed>` method can be used to
+retrieve an item from the cache.
+
+This method will resolve with the cached value on success or with the
+given `$default` value when no item can be found or when an error occurs.
+Similarly, an expired cache item (once the time-to-live is expired) is
+considered a cache miss.
+
+```php
+$cache
+    ->get('foo')
+    ->then('var_dump');
+```
+
+This example fetches the value of the key `foo` and passes it to the
+`var_dump` function. You can use any of the composition provided by
+[promises](https://github.com/reactphp/promise).
+
+#### set()
+
+The `set(string $key, mixed $value, ?float $ttl = null): PromiseInterface<bool>` method can be used to
+store an item in the cache.
+
+This method will resolve with `true` on success or `false` when an error
+occurs. If the cache implementation has to go over the network to store
+it, it may take a while.
+
+The optional `$ttl` parameter sets the maximum time-to-live in seconds
+for this cache item. If this parameter is omitted (or `null`), the item
+will stay in the cache for as long as the underlying implementation
+supports. Trying to access an expired cache item results in a cache miss,
+see also [`get()`](#get).
+
+```php
+$cache->set('foo', 'bar', 60);
+```
+
+This example eventually sets the value of the key `foo` to `bar`. If it
+already exists, it is overridden.
+
+This interface does not enforce any particular TTL resolution, so special
+care may have to be taken if you rely on very high precision with
+millisecond accuracy or below. Cache implementations SHOULD work on a
+best effort basis and SHOULD provide at least second accuracy unless
+otherwise noted. Many existing cache implementations are known to provide
+microsecond or millisecond accuracy, but it's generally not recommended
+to rely on this high precision.
+
+This interface suggests that cache implementations SHOULD use a monotonic
+time source if available. Given that a monotonic time source is only
+available as of PHP 7.3 by default, cache implementations MAY fall back
+to using wall-clock time.
+While this does not affect many common use cases, this is an important
+distinction for programs that rely on a high time precision or on systems
+that are subject to discontinuous time adjustments (time jumps).
+This means that if you store a cache item with a TTL of 30s and then
+adjust your system time forward by 20s, the cache item SHOULD still
+expire in 30s.
+
+#### delete()
+
+The `delete(string $key): PromiseInterface<bool>` method can be used to
+delete an item from the cache.
+
+This method will resolve with `true` on success or `false` when an error
+occurs. When no item for `$key` is found in the cache, it also resolves
+to `true`. If the cache implementation has to go over the network to
+delete it, it may take a while.
+
+```php
+$cache->delete('foo');
+```
+
+This example eventually deletes the key `foo` from the cache. As with
+`set()`, this may not happen instantly and a promise is returned to
+provide guarantees whether or not the item has been removed from cache.
+
+#### getMultiple()
+
+The `getMultiple(string[] $keys, mixed $default = null): PromiseInterface<array>` method can be used to
+retrieve multiple cache items by their unique keys.
+
+This method will resolve with an array of cached values on success or with the
+given `$default` value when an item can not be found or when an error occurs.
+Similarly, an expired cache item (once the time-to-live is expired) is
+considered a cache miss.
+
+```php
+$cache->getMultiple(array('name', 'age'))->then(function (array $values) {
+    $name = $values['name'] ?? 'User';
+    $age = $values['age'] ?? 'n/a';
+
+    echo $name . ' is ' . $age . PHP_EOL;
+});
+```
+
+This example fetches the cache items for the `name` and `age` keys and
+prints some example output. You can use any of the composition provided
+by [promises](https://github.com/reactphp/promise).
+
+#### setMultiple()
+
+The `setMultiple(array $values, ?float $ttl = null): PromiseInterface<bool>` method can be used to
+persist a set of key => value pairs in the cache, with an optional TTL.
+
+This method will resolve with `true` on success or `false` when an error
+occurs. If the cache implementation has to go over the network to store
+it, it may take a while.
+
+The optional `$ttl` parameter sets the maximum time-to-live in seconds
+for these cache items. If this parameter is omitted (or `null`), these items
+will stay in the cache for as long as the underlying implementation
+supports. Trying to access an expired cache items results in a cache miss,
+see also [`getMultiple()`](#getmultiple).
+
+```php
+$cache->setMultiple(array('foo' => 1, 'bar' => 2), 60);
+```
+
+This example eventually sets the list of values - the key `foo` to `1` value 
+and the key `bar` to `2`. If some of the keys already exist, they are overridden.
+
+#### deleteMultiple()
+
+The `setMultiple(string[] $keys): PromiseInterface<bool>` method can be used to
+delete multiple cache items in a single operation.
+
+This method will resolve with `true` on success or `false` when an error
+occurs. When no items for `$keys` are found in the cache, it also resolves
+to `true`. If the cache implementation has to go over the network to
+delete it, it may take a while.
+
+```php
+$cache->deleteMultiple(array('foo', 'bar, 'baz'));
+```
+
+This example eventually deletes keys `foo`, `bar` and `baz` from the cache. 
+As with `setMultiple()`, this may not happen instantly and a promise is returned to
+provide guarantees whether or not the item has been removed from cache.
+
+#### clear()
+
+The `clear(): PromiseInterface<bool>` method can be used to
+wipe clean the entire cache.
+
+This method will resolve with `true` on success or `false` when an error
+occurs. If the cache implementation has to go over the network to
+delete it, it may take a while.
+
+```php
+$cache->clear();
+```
+
+This example eventually deletes all keys from the cache. As with `deleteMultiple()`, 
+this may not happen instantly and a promise is returned to provide guarantees 
+whether or not all the items have been removed from cache.
+
+#### has()
+
+The `has(string $key): PromiseInterface<bool>` method can be used to
+determine whether an item is present in the cache.
+
+This method will resolve with `true` on success or `false` when no item can be found 
+or when an error occurs. Similarly, an expired cache item (once the time-to-live 
+is expired) is considered a cache miss.
+
+```php
+$cache
+    ->has('foo')
+    ->then('var_dump');
+```
+
+This example checks if the value of the key `foo` is set in the cache and passes 
+the result to the `var_dump` function. You can use any of the composition provided by
+[promises](https://github.com/reactphp/promise).
+
+NOTE: It is recommended that has() is only to be used for cache warming type purposes
+and not to be used within your live applications operations for get/set, as this method
+is subject to a race condition where your has() will return true and immediately after,
+another script can remove it making the state of your app out of date.
+
+### ArrayCache
+
+The `ArrayCache` provides an in-memory implementation of the [`CacheInterface`](#cacheinterface).
+
+```php
+$cache = new ArrayCache();
+
+$cache->set('foo', 'bar');
+```
+
+Its constructor accepts an optional `?int $limit` parameter to limit the
+maximum number of entries to store in the LRU cache. If you add more
+entries to this instance, it will automatically take care of removing
+the one that was least recently used (LRU).
+
+For example, this snippet will overwrite the first value and only store
+the last two entries:
+
+```php
+$cache = new ArrayCache(2);
+
+$cache->set('foo', '1');
+$cache->set('bar', '2');
+$cache->set('baz', '3');
+```
+
+This cache implementation is known to rely on wall-clock time to schedule
+future cache expiration times when using any version before PHP 7.3,
+because a monotonic time source is only available as of PHP 7.3 (`hrtime()`).
+While this does not affect many common use cases, this is an important
+distinction for programs that rely on a high time precision or on systems
+that are subject to discontinuous time adjustments (time jumps).
+This means that if you store a cache item with a TTL of 30s on PHP < 7.3
+and then adjust your system time forward by 20s, the cache item may
+expire in 10s. See also [`set()`](#set) for more details.
+
+## Common usage
+
+### Fallback get
+
+A common use case of caches is to attempt fetching a cached value and as a
+fallback retrieve it from the original data source if not found. Here is an
+example of that:
+
+```php
+$cache
+    ->get('foo')
+    ->then(function ($result) {
+        if ($result === null) {
+            return getFooFromDb();
+        }
+        
+        return $result;
+    })
+    ->then('var_dump');
+```
+
+First an attempt is made to retrieve the value of `foo`. A callback function is 
+registered that will call `getFooFromDb` when the resulting value is null. 
+`getFooFromDb` is a function (can be any PHP callable) that will be called if the 
+key does not exist in the cache.
+
+`getFooFromDb` can handle the missing key by returning a promise for the
+actual value from the database (or any other data source). As a result, this
+chain will correctly fall back, and provide the value in both cases.
+
+### Fallback get and set
+
+To expand on the fallback get example, often you want to set the value on the
+cache after fetching it from the data source.
+
+```php
+$cache
+    ->get('foo')
+    ->then(function ($result) {
+        if ($result === null) {
+            return $this->getAndCacheFooFromDb();
+        }
+        
+        return $result;
+    })
+    ->then('var_dump');
+
+public function getAndCacheFooFromDb()
+{
+    return $this->db
+        ->get('foo')
+        ->then(array($this, 'cacheFooFromDb'));
+}
+
+public function cacheFooFromDb($foo)
+{
+    $this->cache->set('foo', $foo);
+
+    return $foo;
+}
+```
+
+By using chaining you can easily conditionally cache the value if it is
+fetched from the database.
+

+# Dns
+
+[![Build Status](https://travis-ci.org/reactphp/dns.svg?branch=master)](https://travis-ci.org/reactphp/dns)
+
+Async DNS resolver for [ReactPHP](https://reactphp.org/).
+
+The main point of the DNS component is to provide async DNS resolution.
+However, it is really a toolkit for working with DNS messages, and could
+easily be used to create a DNS server.

+* [References](#references)
+
+## Basic usage
+
+The most basic usage is to just create a resolver through the resolver
+factory. All you need to give it is a nameserver, then you can start resolving
+names, baby!
+
+```php
+$loop = React\EventLoop\Factory::create();
+
+$config = React\Dns\Config\Config::loadSystemConfigBlocking();
+$server = $config->nameservers ? reset($config->nameservers) : '8.8.8.8';
+
+$factory = new React\Dns\Resolver\Factory();
+$dns = $factory->create($server, $loop);
+
+$dns->resolve('igor.io')->then(function ($ip) {
+    echo "Host: $ip\n";
+});
+
+$loop->run();
+```
+
+See also the [first example](examples).
+
+The `Config` class can be used to load the system default config. This is an
+operation that may access the filesystem and block. Ideally, this method should
+thus be executed only once before the loop starts and not repeatedly while it is
+running.
+Note that this class may return an *empty* configuration if the system config
+can not be loaded. As such, you'll likely want to apply a default nameserver
+as above if none can be found.
+
+> Note that the factory loads the hosts file from the filesystem once when
+  creating the resolver instance.
+  Ideally, this method should thus be executed only once before the loop starts
+  and not repeatedly while it is running.
+
+But there's more.
+
+## Caching
+
+You can cache results by configuring the resolver to use a `CachedExecutor`:
+
+```php
+$loop = React\EventLoop\Factory::create();
+
+$config = React\Dns\Config\Config::loadSystemConfigBlocking();
+$server = $config->nameservers ? reset($config->nameservers) : '8.8.8.8';
+
+$factory = new React\Dns\Resolver\Factory();
+$dns = $factory->createCached($server, $loop);
+
+$dns->resolve('igor.io')->then(function ($ip) {
+    echo "Host: $ip\n";
+});
+
+...
+
+$dns->resolve('igor.io')->then(function ($ip) {
+    echo "Host: $ip\n";
+});
+
+$loop->run();
+```
+
+If the first call returns before the second, only one query will be executed.
+The second result will be served from an in memory cache.
+This is particularly useful for long running scripts where the same hostnames
+have to be looked up multiple times.
+
+See also the [third example](examples).
+
+### Custom cache adapter
+
+By default, the above will use an in memory cache.
+
+You can also specify a custom cache implementing [`CacheInterface`](https://github.com/reactphp/cache) to handle the record cache instead:
+
+```php
+$cache = new React\Cache\ArrayCache();
+$loop = React\EventLoop\Factory::create();
+$factory = new React\Dns\Resolver\Factory();
+$dns = $factory->createCached('8.8.8.8', $loop, $cache);
+```
+
+See also the wiki for possible [cache implementations](https://github.com/reactphp/react/wiki/Users#cache-implementations).
+
+## Resolver
+
+### resolve()
+
+The `resolve(string $domain): PromiseInterface<string,Exception>` method can be used to
+resolve the given $domain name to a single IPv4 address (type `A` query).
+
+```php
+$resolver->resolve('reactphp.org')->then(function ($ip) {
+    echo 'IP for reactphp.org is ' . $ip . PHP_EOL;
+});
+```
+
+This is one of the main methods in this package. It sends a DNS query
+for the given $domain name to your DNS server and returns a single IP
+address on success.
+
+If the DNS server sends a DNS response message that contains more than
+one IP address for this query, it will randomly pick one of the IP
+addresses from the response. If you want the full list of IP addresses
+or want to send a different type of query, you should use the
+[`resolveAll()`](#resolveall) method instead.
+
+If the DNS server sends a DNS response message that indicates an error
+code, this method will reject with a `RecordNotFoundException`. Its
+message and code can be used to check for the response code.
+
+If the DNS communication fails and the server does not respond with a
+valid response message, this message will reject with an `Exception`.
+
+Pending DNS queries can be cancelled by cancelling its pending promise like so:
+
+```php
+$promise = $resolver->resolve('reactphp.org');
+
+$promise->cancel();
+```
+
+### resolveAll()
+
+The `resolveAll(string $host, int $type): PromiseInterface<array,Exception>` method can be used to
+resolve all record values for the given $domain name and query $type.
+
+```php
+$resolver->resolveAll('reactphp.org', Message::TYPE_A)->then(function ($ips) {
+    echo 'IPv4 addresses for reactphp.org ' . implode(', ', $ips) . PHP_EOL;
+});
+
+$resolver->resolveAll('reactphp.org', Message::TYPE_AAAA)->then(function ($ips) {
+    echo 'IPv6 addresses for reactphp.org ' . implode(', ', $ips) . PHP_EOL;
+});
+```
+
+This is one of the main methods in this package. It sends a DNS query
+for the given $domain name to your DNS server and returns a list with all
+record values on success.
+
+If the DNS server sends a DNS response message that contains one or more
+records for this query, it will return a list with all record values
+from the response. You can use the `Message::TYPE_*` constants to control
+which type of query will be sent. Note that this method always returns a
+list of record values, but each record value type depends on the query
+type. For example, it returns the IPv4 addresses for type `A` queries,
+the IPv6 addresses for type `AAAA` queries, the hostname for type `NS`,
+`CNAME` and `PTR` queries and structured data for other queries. See also
+the `Record` documentation for more details.
+
+If the DNS server sends a DNS response message that indicates an error
+code, this method will reject with a `RecordNotFoundException`. Its
+message and code can be used to check for the response code.
+
+If the DNS communication fails and the server does not respond with a
+valid response message, this message will reject with an `Exception`.
+
+Pending DNS queries can be cancelled by cancelling its pending promise like so:
+
+```php
+$promise = $resolver->resolveAll('reactphp.org', Message::TYPE_AAAA);
+
+$promise->cancel();
+```
+
+## Advanced Usage
+
+### UdpTransportExecutor
+
+The `UdpTransportExecutor` can be used to
+send DNS queries over a UDP transport.
+
+This is the main class that sends a DNS query to your DNS server and is used
+internally by the `Resolver` for the actual message transport.
+
+For more advanced usages one can utilize this class directly.
+The following example looks up the `IPv6` address for `igor.io`.
+
+```php
+$loop = Factory::create();
+$executor = new UdpTransportExecutor($loop);
+
+$executor->query(
+    '8.8.8.8:53', 
+    new Query($name, Message::TYPE_AAAA, Message::CLASS_IN)
+)->then(function (Message $message) {
+    foreach ($message->answers as $answer) {
+        echo 'IPv6: ' . $answer->data . PHP_EOL;
+    }
+}, 'printf');
+
+$loop->run();
+```
+
+See also the [fourth example](examples).
+
+Note that this executor does not implement a timeout, so you will very likely
+want to use this in combination with a `TimeoutExecutor` like this:
+
+```php
+$executor = new TimeoutExecutor(
+    new UdpTransportExecutor($loop),
+    3.0,
+    $loop
+);
+```
+
+Also note that this executor uses an unreliable UDP transport and that it
+does not implement any retry logic, so you will likely want to use this in
+combination with a `RetryExecutor` like this:
+
+```php
+$executor = new RetryExecutor(
+    new TimeoutExecutor(
+        new UdpTransportExecutor($loop),
+        3.0,
+        $loop
+    )
+);
+```
+
+Note that this executor is entirely async and as such allows you to execute
+any number of queries concurrently. You should probably limit the number of
+concurrent queries in your application or you're very likely going to face
+rate limitations and bans on the resolver end. For many common applications,
+you may want to avoid sending the same query multiple times when the first
+one is still pending, so you will likely want to use this in combination with
+a `CoopExecutor` like this:
+
+```php
+$executor = new CoopExecutor(
+    new RetryExecutor(
+        new TimeoutExecutor(
+            new UdpTransportExecutor($loop),
+            3.0,
+            $loop
+        )
+    )
+);
+```
+
+> Internally, this class uses PHP's UDP sockets and does not take advantage
+  of [react/datagram](https://github.com/reactphp/datagram) purely for
+  organizational reasons to avoid a cyclic dependency between the two
+  packages. Higher-level components should take advantage of the Datagram
+  component instead of reimplementing this socket logic from scratch.
+
+### HostsFileExecutor
+
+Note that the above `UdpTransportExecutor` class always performs an actual DNS query.
+If you also want to take entries from your hosts file into account, you may
+use this code:
+
+```php
+$hosts = \React\Dns\Config\HostsFile::loadFromPathBlocking();
+
+$executor = new UdpTransportExecutor($loop);
+$executor = new HostsFileExecutor($hosts, $executor);
+
+$executor->query(
+    '8.8.8.8:53', 
+    new Query('localhost', Message::TYPE_A, Message::CLASS_IN)
+);
+```
+
+## Install
+
+The recommended way to install this library is [through Composer](https://getcomposer.org).
+[New to Composer?](https://getcomposer.org/doc/00-intro.md)
+
+This will install the latest supported version:
+
+```bash
+$ composer require react/dns:^0.4.19
+```
+
+See also the [CHANGELOG](CHANGELOG.md) for details about version upgrades.
+
+This project aims to run on any platform and thus does not require any PHP
+extensions and supports running on legacy PHP 5.3 through current PHP 7+ and
+HHVM.
+It's *highly recommended to use PHP 7+* for this project.
+
+## Tests
+
+To run the test suite, you first need to clone this repo and then install all
+dependencies [through Composer](https://getcomposer.org):
+
+```bash
+$ composer install
+```
+
+To run the test suite, go to the project root and run:
+
+```bash
+$ php vendor/bin/phpunit
+```
+
+The test suite also contains a number of functional integration tests that rely
+on a stable internet connection.
+If you do not want to run these, they can simply be skipped like this:
+
+```bash
+$ php vendor/bin/phpunit --exclude-group internet
+```

+     * easily without having to worry about DNS internals and its binary transport:
+     *
+     * - A:

+     *   IPv6 address string, for example "::1".
+     * - CNAME / PTR / NS:
+     *   The hostname without trailing dot, for example "reactphp.org".
+     * - TXT:
+     *   List of string values, for example `["v=spf1 include:example.com"]`.
+     *   This is commonly a list with only a single string value, but this
+     *   technically allows multiple strings (0-255 bytes each) in a single
+     *   record. This is rarely used and depending on application you may want
+     *   to join these together or handle them separately. Each string can
+     *   transport any binary data, its character encoding is not defined (often
+     *   ASCII/UTF-8 in practice). [RFC 1464](https://tools.ietf.org/html/rfc1464)
+     *   suggests using key-value pairs such as `["name=test","version=1"]`, but
+     *   interpretation of this is not enforced and left up to consumers of this
+     *   library (used for DNS-SD/Zeroconf and others).
+     * - MX:
+     *   Mail server priority (UINT16) and target hostname without trailing dot,
+     *   for example `{"priority":10,"target":"mx.example.com"}`.
+     *   The payload data uses an associative array with fixed keys "priority"
+     *   (also commonly referred to as weight or preference) and "target" (also
+     *   referred to as exchange). If a response message contains multiple
+     *   records of this type, targets should be sorted by priority (lowest
+     *   first) - this is left up to consumers of this library (used for SMTP).
+     * - SRV:
+     *   Service priority (UINT16), service weight (UINT16), service port (UINT16)
+     *   and target hostname without trailing dot, for example
+     *   `{"priority":10,"weight":50,"port":8080,"target":"example.com"}`.
+     *   The payload data uses an associative array with fixed keys "priority",
+     *   "weight", "port" and "target" (also referred to as name).
+     *   The target may be an empty host name string if the service is decidedly
+     *   not available. If a response message contains multiple records of this
+     *   type, targets should be sorted by priority (lowest first) and selected
+     *   randomly according to their weight - this is left up to consumers of
+     *   this library, see also [RFC 2782](https://tools.ietf.org/html/rfc2782)
+     *   for more details.
+     * - SOA:
+     *   Includes master hostname without trailing dot, responsible person email
+     *   as hostname without trailing dot and serial, refresh, retry, expire and
+     *   minimum times in seconds (UINT32 each), for example:
+     *   `{"mname":"ns.example.com","rname":"hostmaster.example.com","serial":
+     *   2018082601,"refresh":3600,"retry":1800,"expire":60000,"minimum":3600}`.
+     * - Any other unknown type:
+     *   An opaque binary string containing the RDATA as transported in the DNS
+     *   record. For forwards compatibility, you should not rely on this format
+     *   for unknown types. Future versions may add support for new types and

+/**
+ * Cooperatively resolves hosts via the given base executor to ensure same query is not run concurrently
+ *
+ * Wraps an existing `ExecutorInterface` to keep tracking of pending queries
+ * and only starts a new query when the same query is not already pending. Once
+ * the underlying query is fulfilled/rejected, it will forward its value to all
+ * promises awaiting the same query.
+ *
+ * This means it will not limit concurrency for queries that differ, for example
+ * when sending many queries for different host names or types.
+ *
+ * This is useful because all executors are entirely async and as such allow you
+ * to execute any number of queries concurrently. You should probably limit the
+ * number of concurrent queries in your application or you're very likely going
+ * to face rate limitations and bans on the resolver end. For many common
+ * applications, you may want to avoid sending the same query multiple times
+ * when the first one is still pending, so you will likely want to use this in
+ * combination with some other executor like this:
+ *
+ * ```php
+ * $executor = new CoopExecutor(
+ *     new RetryExecutor(
+ *         new TimeoutExecutor(
+ *             new UdpTransportExecutor($loop),

+/**
+ * Send DNS queries over a UDP transport.
+ *
+ * This is the main class that sends a DNS query to your DNS server and is used
+ * internally by the `Resolver` for the actual message transport.
+ *
+ * For more advanced usages one can utilize this class directly.
+ * The following example looks up the `IPv6` address for `igor.io`.
+ *
+ * ```php
+ * $loop = Factory::create();
+ * $executor = new UdpTransportExecutor($loop);
+ *
+ * $executor->query(
+ *     '8.8.8.8:53',
+ *     new Query($name, Message::TYPE_AAAA, Message::CLASS_IN)
+ * )->then(function (Message $message) {
+ *     foreach ($message->answers as $answer) {
+ *         echo 'IPv6: ' . $answer->data . PHP_EOL;
+ *     }
+ * }, 'printf');
+ *
+ * $loop->run();
+ * ```
+ *
+ * See also the [fourth example](examples).
+ *
+ * Note that this executor does not implement a timeout, so you will very likely
+ * want to use this in combination with a `TimeoutExecutor` like this:
+ *
+ * ```php
+ * $executor = new TimeoutExecutor(
+ *     new UdpTransportExecutor($loop),
+ *     3.0,
+ *     $loop
+ * );
+ * ```
+ *
+ * Also note that this executor uses an unreliable UDP transport and that it
+ * does not implement any retry logic, so you will likely want to use this in
+ * combination with a `RetryExecutor` like this:
+ *
+ * ```php
+ * $executor = new RetryExecutor(
+ *     new TimeoutExecutor(
+ *         new UdpTransportExecutor($loop),
+ *         3.0,
+ *         $loop
+ *     )
+ * );
+ * ```
+ *
+ * Note that this executor is entirely async and as such allows you to execute
+ * any number of queries concurrently. You should probably limit the number of
+ * concurrent queries in your application or you're very likely going to face
+ * rate limitations and bans on the resolver end. For many common applications,
+ * you may want to avoid sending the same query multiple times when the first
+ * one is still pending, so you will likely want to use this in combination with
+ * a `CoopExecutor` like this:
+ *
+ * ```php
+ * $executor = new CoopExecutor(
+ *     new RetryExecutor(
+ *         new TimeoutExecutor(
+ *             new UdpTransportExecutor($loop),
+ *             3.0,
+ *             $loop
+ *         )
+ *     )
+ * );
+ * ```
+ *
+ * > Internally, this class uses PHP's UDP sockets and does not take advantage
+ *   of [react/datagram](https://github.com/reactphp/datagram) purely for
+ *   organizational reasons to avoid a cyclic dependency between the two
+ *   packages. Higher-level components should take advantage of the Datagram
+ *   component instead of reimplementing this socket logic from scratch.

+# EventLoop Component
+
+[![Build Status](https://travis-ci.org/reactphp/event-loop.svg?branch=master)](https://travis-ci.org/reactphp/event-loop)
+[![Code Climate](https://codeclimate.com/github/reactphp/event-loop/badges/gpa.svg)](https://codeclimate.com/github/reactphp/event-loop)
+
+Event loop abstraction layer that libraries can use for evented I/O.
+
+In order for async based libraries to be interoperable, they need to use the
+same event loop. This component provides a common `LoopInterface` that any
+library can target. This allows them to be used in the same loop, with one
+single `run()` call that is controlled by the user.
+

+* [Quickstart example](#quickstart-example)
+* [Usage](#usage)
+* [Loop implementations](#loop-implementations)
+* [Install](#install)
+* [Tests](#tests)
+* [License](#license)
+
+## Quickstart example
+
+Here is an async HTTP server built with just the event loop.
+
+```php
+$loop = React\EventLoop\Factory::create();
+
+$server = stream_socket_server('tcp://127.0.0.1:8080');
+stream_set_blocking($server, 0);
+
+$loop->addReadStream($server, function ($server) use ($loop) {
+    $conn = stream_socket_accept($server);
+    $data = "HTTP/1.1 200 OK\r\nContent-Length: 3\r\n\r\nHi\n";
+    $loop->addWriteStream($conn, function ($conn) use (&$data, $loop) {
+        $written = fwrite($conn, $data);
+        if ($written === strlen($data)) {
+            fclose($conn);
+            $loop->removeStream($conn);
+        } else {
+            $data = substr($data, $written);
+        }
+    });
+});
+
+$loop->addPeriodicTimer(5, function () {
+    $memory = memory_get_usage() / 1024;
+    $formatted = number_format($memory, 3).'K';
+    echo "Current memory usage: {$formatted}\n";
+});
+
+$loop->run();
+```
+
+## Usage
+
+Typical applications use a single event loop which is created at the beginning
+and run at the end of the program.
+
+```php
+// [1]
+$loop = React\EventLoop\Factory::create();
+
+// [2]
+$loop->addPeriodicTimer(1, function () {
+    echo "Tick\n";
+});
+
+$stream = new React\Stream\ReadableResourceStream(
+    fopen('file.txt', 'r'),
+    $loop
+);
+
+// [3]
+$loop->run();
+```
+
+1. The loop instance is created at the beginning of the program. A convenience
+   factory `React\EventLoop\Factory::create()` is provided by this library which
+   picks the best available [loop implementation](#loop-implementations).
+2. The loop instance is used directly or passed to library and application code.
+   In this example, a periodic timer is registered with the event loop which
+   simply outputs `Tick` every second and a
+   [readable stream](https://github.com/reactphp/stream#readableresourcestream)
+   is created by using ReactPHP's
+   [stream component](https://github.com/reactphp/stream) for demonstration
+   purposes.
+3. The loop is run with a single `$loop->run()` call at the end of the program.
+
+## Loop implementations
+
+In addition to the interface there are the following implementations provided:
+
+* `StreamSelectLoop`: This is the only implementation which works out of the
+  box with PHP. It does a simple `select` system call. It's not the most
+  performant of loops, but still does the job quite well.
+
+* `LibEventLoop`: This uses the `libevent` pecl extension. `libevent` itself
+  supports a number of system-specific backends (epoll, kqueue).
+
+* `LibEvLoop`: This uses the `libev` pecl extension
+  ([github](https://github.com/m4rw3r/php-libev)). It supports the same
+  backends as libevent.
+
+* `ExtEventLoop`: This uses the `event` pecl extension. It supports the same
+  backends as libevent.
+
+All of the loops support these features:
+
+* File descriptor polling
+* One-off timers
+* Periodic timers
+* Deferred execution of callbacks
+
+## Install
+
+The recommended way to install this library is [through Composer](http://getcomposer.org).
+[New to Composer?](http://getcomposer.org/doc/00-intro.md)

+
+## Usage
+
+This lightweight library consists only of a few simple functions.
+All functions reside under the `React\Promise\Timer` namespace.
+
+The below examples assume you use an import statement similar to this:
+
+```php
+use React\Promise\Timer;
+
+Timer\timeout(…);
+```
+
+Alternatively, you can also refer to them with their fully-qualified name:
+
+```php
+\React\Promise\Timer\timeout(…);
+```
+
+### timeout()
+
+The `timeout(PromiseInterface $promise, $time, LoopInterface $loop)` function
+can be used to *cancel* operations that take *too long*.
+You need to pass in an input `$promise` that represents a pending operation and timeout parameters.
+It returns a new `Promise` with the following resolution behavior:
+
+* If the input `$promise` resolves before `$time` seconds, resolve the resulting promise with its fulfillment value.
+* If the input `$promise` rejects before `$time` seconds, reject the resulting promise with its rejection value.
+* If the input `$promise` does not settle before `$time` seconds, *cancel* the operation and reject the resulting promise with a [`TimeoutException`](#timeoutexception).
+
+Internally, the given `$time` value will be used to start a timer that will
+*cancel* the pending operation once it triggers.
+This implies that if you pass a really small (or negative) value, it will still
+start a timer and will thus trigger at the earliest possible time in the future.
+
+If the input `$promise` is already settled, then the resulting promise will
+resolve or reject immediately without starting a timer at all.
+
+A common use case for handling only resolved values looks like this:
+
+```php
+$promise = accessSomeRemoteResource();
+Timer\timeout($promise, 10.0, $loop)->then(function ($value) {
+    // the operation finished within 10.0 seconds
+});
+```
+
+A more complete example could look like this:
+
+```php
+$promise = accessSomeRemoteResource();
+Timer\timeout($promise, 10.0, $loop)->then(
+    function ($value) {
+        // the operation finished within 10.0 seconds
+    },
+    function ($error) {
+        if ($error instanceof Timer\TimeoutException) {
+            // the operation has failed due to a timeout
+        } else {
+            // the input operation has failed due to some other error
+        }
+    }
+);
+```
+
+Or if you're using [react/promise v2.2.0](https://github.com/reactphp/promise) or up:
+
+```php
+Timer\timeout($promise, 10.0, $loop)
+    ->then(function ($value) {
+        // the operation finished within 10.0 seconds
+    })
+    ->otherwise(function (Timer\TimeoutException $error) {
+        // the operation has failed due to a timeout
+    })
+    ->otherwise(function ($error) {
+        // the input operation has failed due to some other error
+    })
+;
+```
+
+#### Timeout cancellation
+
+As discussed above, the [`timeout()`](#timeout) function will *cancel* the
+underlying operation if it takes *too long*.
+This means that you can be sure the resulting promise will then be rejected
+with a [`TimeoutException`](#timeoutexception).
+
+However, what happens to the underlying input `$promise` is a bit more tricky:
+Once the timer fires, we will try to call
+[`$promise->cancel()`](https://github.com/reactphp/promise#cancellablepromiseinterfacecancel)
+on the input `$promise` which in turn invokes its [cancellation handler](#cancellation-handler).
+
+This means that it's actually up the input `$promise` to handle
+[cancellation support](https://github.com/reactphp/promise#cancellablepromiseinterface).
+
+* A common use case involves cleaning up any resources like open network sockets or
+  file handles or terminating external processes or timers.
+
+* If the given input `$promise` does not support cancellation, then this is a NO-OP.
+  This means that while the resulting promise will still be rejected, the underlying
+  input `$promise` may still be pending and can hence continue consuming resources.
+
+See the following chapter for more details on the cancellation handler.
+
+#### Cancellation handler
+
+For example, an implementation for the above operation could look like this:
+
+```php
+function accessSomeRemoteResource()
+{
+    return new Promise(
+        function ($resolve, $reject) use (&$socket) {
+            // this will be called once the promise is created
+            // a common use case involves opening any resources and eventually resolving
+            $socket = createSocket();
+            $socket->on('data', function ($data) use ($resolve) {
+                $resolve($data);
+            });
+        },
+        function ($resolve, $reject) use (&$socket) {
+            // this will be called once calling `cancel()` on this promise
+            // a common use case involves cleaning any resources and then rejecting
+            $socket->close();
+            $reject(new \RuntimeException('Operation cancelled'));
+        }
+    );
+}
+```
+
+In this example, calling `$promise->cancel()` will invoke the registered cancellation
+handler which then closes the network socket and rejects the `Promise` instance.
+
+If no cancellation handler is passed to the `Promise` constructor, then invoking
+its `cancel()` method it is effectively a NO-OP.
+This means that it may still be pending and can hence continue consuming resources.
+
+For more details on the promise cancellation, please refer to the
+[Promise documentation](https://github.com/reactphp/promise#cancellablepromiseinterface).
+
+#### Input cancellation
+
+Irrespective of the timeout handling, you can also explicitly `cancel()` the
+input `$promise` at any time.
+This means that the `timeout()` handling does not affect cancellation of the
+input `$promise`, as demonstrated in the following example:
+
+```php
+$promise = accessSomeRemoteResource();
+$timeout = Timer\timeout($promise, 10.0, $loop);
+
+$promise->cancel();
+```
+
+The registered [cancellation handler](#cancellation-handler) is responsible for
+handling the `cancel()` call:
+
+* A described above, a common use involves resource cleanup and will then *reject*
+  the `Promise`.
+  If the input `$promise` is being rejected, then the timeout will be aborted
+  and the resulting promise will also be rejected.
+* If the input `$promise` is still pending, then the timout will continue
+  running until the timer expires.
+  The same happens if the input `$promise` does not register a
+  [cancellation handler](#cancellation-handler). 
+
+#### Output cancellation
+
+Similarily, you can also explicitly `cancel()` the resulting promise like this:
+
+```php
+$promise = accessSomeRemoteResource();
+$timeout = Timer\timeout($promise, 10.0, $loop);
+
+$timeout->cancel();
+```
+
+Note how this looks very similar to the above [input cancellation](#input-cancellation)
+example. Accordingly, it also behaves very similar.
+
+Calling `cancel()` on the resulting promise will merely try
+to `cancel()` the input `$promise`.
+This means that we do not take over responsibility of the outcome and it's
+entirely up to the input `$promise` to handle cancellation support.
+
+The registered [cancellation handler](#cancellation-handler) is responsible for
+handling the `cancel()` call:
+
+* As described above, a common use involves resource cleanup and will then *reject*
+  the `Promise`.
+  If the input `$promise` is being rejected, then the timeout will be aborted
+  and the resulting promise will also be rejected.
+* If the input `$promise` is still pending, then the timout will continue
+  running until the timer expires.
+  The same happens if the input `$promise` does not register a
+  [cancellation handler](#cancellation-handler). 
+
+To re-iterate, note that calling `cancel()` on the resulting promise will merely
+try to cancel the input `$promise` only.
+It is then up to the cancellation handler of the input promise to settle the promise.
+If the input promise is still pending when the timeout occurs, then the normal
+[timeout cancellation](#timeout-cancellation) handling will trigger, effectively rejecting
+the output promise with a [`TimeoutException`](#timeoutexception).
+
+This is done for consistency with the [timeout cancellation](#timeout-cancellation)
+handling and also because it is assumed this is often used like this:
+
+```php
+$timeout = Timer\timeout(accessSomeRemoteResource(), 10.0, $loop);
+
+$timeout->cancel();
+```
+
+As described above, this example works as expected and cleans up any resources
+allocated for the input `$promise`.
+
+Note that if the given input `$promise` does not support cancellation, then this
+is a NO-OP.
+This means that while the resulting promise will still be rejected after the
+timeout, the underlying input `$promise` may still be pending and can hence
+continue consuming resources.
+
+#### Collections
+
+If you want to wait for multiple promises to resolve, you can use the normal promise primitives like this:
+
+```php
+$promises = array(
+    accessSomeRemoteResource(),
+    accessSomeRemoteResource(),
+    accessSomeRemoteResource()
+);
+
+$promise = \React\Promise\all($promises);
+
+Timer\timeout($promise, 10, $loop)->then(function ($values) {
+    // *all* promises resolved
+});
+```
+
+The applies to all promise collection primitives alike, i.e. `all()`, `race()`, `any()`, `some()` etc.
+
+For more details on the promise primitives, please refer to the
+[Promise documentation](https://github.com/reactphp/promise#functions).
+
+### resolve()
+
+The `resolve($time, LoopInterface $loop)` function can be used to create a new Promise that
+resolves in `$time` seconds with the `$time` as the fulfillment value.
+
+```php
+Timer\resolve(1.5, $loop)->then(function ($time) {
+    echo 'Thanks for waiting ' . $time . ' seconds' . PHP_EOL;
+});
+```
+
+Internally, the given `$time` value will be used to start a timer that will
+resolve the promise once it triggers.
+This implies that if you pass a really small (or negative) value, it will still
+start a timer and will thus trigger at the earliest possible time in the future.
+
+#### Resolve cancellation
+
+You can explicitly `cancel()` the resulting timer promise at any time:
+
+```php
+$timer = Timer\resolve(2.0, $loop);
+
+$timer->cancel();
+```
+
+This will abort the timer and *reject* with a `RuntimeException`.
+
+### reject()
+
+The `reject($time, LoopInterface $loop)` function can be used to create a new Promise
+which rejects in `$time` seconds with a `TimeoutException`.
+
+```php
+Timer\reject(2.0, $loop)->then(null, function (TimeoutException $e) {
+    echo 'Rejected after ' . $e->getTimeout() . ' seconds ' . PHP_EOL;
+});
+```
+
+Internally, the given `$time` value will be used to start a timer that will
+reject the promise once it triggers.
+This implies that if you pass a really small (or negative) value, it will still
+start a timer and will thus trigger at the earliest possible time in the future.
+
+This function complements the [`resolve()`](#resolve) function
+and can be used as a basic building block for higher-level promise consumers.
+
+#### Reject cancellation
+
+You can explicitly `cancel()` the resulting timer promise at any time:
+
+```php
+$timer = Timer\reject(2.0, $loop);
+
+$timer->cancel();
+```
+
+This will abort the timer and *reject* with a `RuntimeException`.
+
+### TimeoutException
+
+The `TimeoutException` extends PHP's built-in `RuntimeException`.
+
+The `getTimeout()` method can be used to get the timeout value in seconds.
+

+CHANGELOG for 2.x
+=================
+
+* 2.7.1 (2018-01-07)
+
+    *   Fix: file_exists warning when resolving with long strings.
+        (#130 by @sbesselsen)
+    *   Improve performance by prefixing all global functions calls with \ to skip the look up and resolve process and go straight to the global function.
+        (#133 by @WyriHaximus)
+
+* 2.7.0 (2018-06-13)
+
+    *   Feature: Improve memory consumption for pending promises by using static internal callbacks without binding to self.
+        (#124 by @clue)
+
+* 2.6.0 (2018-06-11)
+
+    *   Feature: Significantly improve memory consumption and performance by only passing resolver args
+        to resolver and canceller if callback requires them. Also use static callbacks without
+        binding to promise, clean up canceller function reference when they are no longer
+        needed and hide resolver and canceller references from call stack on PHP 7+.
+        (#113, #115, #116, #117, #118, #119 and #123 by @clue)
+
+        These changes combined mean that rejecting promises with an `Exception` should
+        no longer cause any internal circular references which could cause some unexpected
+        memory growth in previous versions. By explicitly avoiding and explicitly
+        cleaning up said references, we can avoid relying on PHP's circular garbage collector
+        to kick in which significantly improves performance when rejecting many promises.
+
+    *   Mark legacy progress support / notification API as deprecated
+        (#112 by @clue)
+
+    *   Recommend rejecting promises by throwing an exception
+        (#114 by @jsor)
+
+    *   Improve documentation to properly instantiate LazyPromise
+        (#121 by @holtkamp)
+
+    *   Follower cancellation propagation was originally planned for this release
+        but has been reverted for now and is planned for a future release.
+        (#99 by @jsor and #122 by @clue)
+
+* 2.5.1 (2017-03-25)
+
+    * Fix circular references when resolving with a promise which follows
+      itself (#94).
+
+* 2.5.0 (2016-12-22)
+
+    * Revert automatic cancellation of pending collection promises once the
+      output promise resolves. This was introduced in 42d86b7 (PR #36, released
+      in [v2.3.0](https://github.com/reactphp/promise/releases/tag/v2.3.0)) and
+      was both unintended and backward incompatible.
+
+      If you need automatic cancellation, you can use something like:
+
+      ```php
+      function allAndCancel(array $promises)
+      {
+           return \React\Promise\all($promises)
+               ->always(function() use ($promises) {
+                   foreach ($promises as $promise) {
+                       if ($promise instanceof \React\Promise\CancellablePromiseInterface) {
+                           $promise->cancel();
+                       }
+                   }
+              });
+      }
+      ```
+    * `all()` and `map()` functions now preserve the order of the array (#77).
+    * Fix circular references when resolving a promise with itself (#71).
+
+* 2.4.1 (2016-05-03)
+
+    * Fix `some()` not cancelling pending promises when too much input promises
+      reject (16ff799).
+
+* 2.4.0 (2016-03-31)
+
+    * Support foreign thenables in `resolve()`.
+      Any object that provides a `then()` method is now assimilated to a trusted
+      promise that follows the state of this thenable (#52).
+    * Fix `some()` and `any()` for input arrays containing not enough items
+      (#34).
+
+* 2.3.0 (2016-03-24)
+
+    * Allow cancellation of promises returned by functions working on promise
+      collections (#36).
+    * Handle `\Throwable` in the same way as `\Exception` (#51 by @joshdifabio).
+
+* 2.2.2 (2016-02-26)
+
+    * Fix cancellation handlers called multiple times (#47 by @clue).
+
+* 2.2.1 (2015-07-03)
+
+    * Fix stack error when resolving a promise in its own fulfillment or
+      rejection handlers.
+
+* 2.2.0 (2014-12-30)
+
+    * Introduce new `ExtendedPromiseInterface` implemented by all promises.
+    * Add new `done()` method (part of the `ExtendedPromiseInterface`).
+    * Add new `otherwise()` method (part of the `ExtendedPromiseInterface`).
+    * Add new `always()` method (part of the `ExtendedPromiseInterface`).
+    * Add new `progress()` method (part of the `ExtendedPromiseInterface`).
+    * Rename `Deferred::progress` to `Deferred::notify` to avoid confusion with
+      `ExtendedPromiseInterface::progress` (a `Deferred::progress` alias is
+      still available for backward compatibility)
+    * `resolve()` now always returns a `ExtendedPromiseInterface`.
+
+* 2.1.0 (2014-10-15)
+
+    * Introduce new `CancellablePromiseInterface` implemented by all promises.
+    * Add new `cancel()` method (part of the `CancellablePromiseInterface`).
+
+* 2.0.0 (2013-12-10)
+
+    New major release. The goal is to streamline the API and to make it more
+    compliant with other promise libraries and especially with the new upcoming
+    [ES6 promises specification](https://github.com/domenic/promises-unwrapping/).
+
+    * Add standalone Promise class.
+    * Add new `race()` function.
+    * BC break: Bump minimum PHP version to PHP 5.4.
+    * BC break: Remove `ResolverInterface` and `PromiseInterface` from 
+      `Deferred`.
+    * BC break: Change signature of `PromiseInterface`.
+    * BC break: Remove `When` and `Util` classes and move static methods to
+      functions.
+    * BC break: `FulfilledPromise` and `RejectedPromise` now throw an exception
+      when initialized with a promise instead of a value/reason.
+    * BC break: `Deferred::resolve()` and `Deferred::reject()` no longer return
+      a promise.

+Introduction
+------------
+
+Promise is a library implementing
+[CommonJS Promises/A](http://wiki.commonjs.org/wiki/Promises/A) for PHP.
+
+It also provides several other useful promise-related concepts, such as joining
+multiple promises and mapping and reducing collections of promises.
+
+If you've never heard about promises before,
+[read this first](https://gist.github.com/3889970).
+
+Concepts
+--------
+
+### Deferred
+
+A **Deferred** represents a computation or unit of work that may not have
+completed yet. Typically (but not always), that computation will be something
+that executes asynchronously and completes at some point in the future.
+
+### Promise
+
+While a deferred represents the computation itself, a **Promise** represents
+the result of that computation. Thus, each deferred has a promise that acts as
+a placeholder for its actual result.
+
+API
+---
+
+### Deferred
+
+A deferred represents an operation whose resolution is pending. It has separate
+promise and resolver parts.
+
+```php
+$deferred = new React\Promise\Deferred();
+
+$promise = $deferred->promise();
+
+$deferred->resolve(mixed $value = null);
+$deferred->reject(mixed $reason = null);
+$deferred->notify(mixed $update = null);
+```
+
+The `promise` method returns the promise of the deferred.
+
+The `resolve` and `reject` methods control the state of the deferred.
+
+The deprecated `notify` method is for progress notification.
+
+The constructor of the `Deferred` accepts an optional `$canceller` argument.
+See [Promise](#promise-2) for more information.
+
+#### Deferred::promise()
+
+```php
+$promise = $deferred->promise();
+```
+
+Returns the promise of the deferred, which you can hand out to others while
+keeping the authority to modify its state to yourself.
+
+#### Deferred::resolve()
+
+```php
+$deferred->resolve(mixed $value = null);
+```
+
+Resolves the promise returned by `promise()`. All consumers are notified by
+having `$onFulfilled` (which they registered via `$promise->then()`) called with
+`$value`.
+
+If `$value` itself is a promise, the promise will transition to the state of
+this promise once it is resolved.
+
+#### Deferred::reject()
+
+```php
+$deferred->reject(mixed $reason = null);
+```
+
+Rejects the promise returned by `promise()`, signalling that the deferred's
+computation failed.
+All consumers are notified by having `$onRejected` (which they registered via
+`$promise->then()`) called with `$reason`.
+
+If `$reason` itself is a promise, the promise will be rejected with the outcome
+of this promise regardless whether it fulfills or rejects.
+
+#### Deferred::notify()
+
+> Deprecated in v2.6.0: Progress support is deprecated and should not be used anymore.
+
+```php
+$deferred->notify(mixed $update = null);
+```
+
+Triggers progress notifications, to indicate to consumers that the computation
+is making progress toward its result.
+
+All consumers are notified by having `$onProgress` (which they registered via
+`$promise->then()`) called with `$update`.
+
+### PromiseInterface
+
+The promise interface provides the common interface for all promise
+implementations.
+
+A promise represents an eventual outcome, which is either fulfillment (success)
+and an associated value, or rejection (failure) and an associated reason.
+
+Once in the fulfilled or rejected state, a promise becomes immutable.
+Neither its state nor its result (or error) can be modified.
+
+#### Implementations
+
+* [Promise](#promise-2)
+* [FulfilledPromise](#fulfilledpromise)
+* [RejectedPromise](#rejectedpromise)
+* [LazyPromise](#lazypromise)
+
+#### PromiseInterface::then()
+
+```php
+$transformedPromise = $promise->then(callable $onFulfilled = null, callable $onRejected = null, callable $onProgress = null);
+```
+
+Transforms a promise's value by applying a function to the promise's fulfillment
+or rejection value. Returns a new promise for the transformed result.
+
+The `then()` method registers new fulfilled, rejection and progress handlers
+with a promise (all parameters are optional):
+
+  * `$onFulfilled` will be invoked once the promise is fulfilled and passed
+    the result as the first argument.
+  * `$onRejected` will be invoked once the promise is rejected and passed the
+    reason as the first argument.
+  * `$onProgress` (deprecated) will be invoked whenever the producer of the promise
+    triggers progress notifications and passed a single argument (whatever it
+    wants) to indicate progress.
+
+It returns a new promise that will fulfill with the return value of either
+`$onFulfilled` or `$onRejected`, whichever is called, or will reject with
+the thrown exception if either throws.
+
+A promise makes the following guarantees about handlers registered in
+the same call to `then()`:
+
+  1. Only one of `$onFulfilled` or `$onRejected` will be called,
+     never both.
+  2. `$onFulfilled` and `$onRejected` will never be called more
+     than once.
+  3. `$onProgress` (deprecated) may be called multiple times.
+

+* [reject()](#reject) - Creating a rejected promise
+* [ExtendedPromiseInterface::done()](#extendedpromiseinterfacedone)
+* [done() vs. then()](#done-vs-then)
+
+### ExtendedPromiseInterface
+
+The ExtendedPromiseInterface extends the PromiseInterface with useful shortcut
+and utility methods which are not part of the Promises/A specification.
+
+#### Implementations
+
+* [Promise](#promise-1)
+* [FulfilledPromise](#fulfilledpromise)
+* [RejectedPromise](#rejectedpromise)
+* [LazyPromise](#lazypromise)
+
+#### ExtendedPromiseInterface::done()
+
+```php
+$promise->done(callable $onFulfilled = null, callable $onRejected = null, callable $onProgress = null);
+```
+
+Consumes the promise's ultimate value if the promise fulfills, or handles the
+ultimate error.
+
+It will cause a fatal error if either `$onFulfilled` or `$onRejected` throw or
+return a rejected promise.
+
+Since the purpose of `done()` is consumption rather than transformation,
+`done()` always returns `null`.
+
+#### See also
+
+* [PromiseInterface::then()](#promiseinterfacethen)
+* [done() vs. then()](#done-vs-then)
+
+#### ExtendedPromiseInterface::otherwise()
+
+```php
+$promise->otherwise(callable $onRejected);
+```
+
+Registers a rejection handler for promise. It is a shortcut for:
+
+```php
+$promise->then(null, $onRejected);
+```
+
+Additionally, you can type hint the `$reason` argument of `$onRejected` to catch
+only specific errors.
+
+```php
+$promise
+    ->otherwise(function (\RuntimeException $reason) {
+        // Only catch \RuntimeException instances
+        // All other types of errors will propagate automatically
+    })
+    ->otherwise(function ($reason) {
+        // Catch other errors
+    )};
+```
+
+#### ExtendedPromiseInterface::always()
+
+```php
+$newPromise = $promise->always(callable $onFulfilledOrRejected);
+```
+
+Allows you to execute "cleanup" type tasks in a promise chain.
+
+It arranges for `$onFulfilledOrRejected` to be called, with no arguments,
+when the promise is either fulfilled or rejected.
+
+* If `$promise` fulfills, and `$onFulfilledOrRejected` returns successfully,
+  `$newPromise` will fulfill with the same value as `$promise`.
+* If `$promise` fulfills, and `$onFulfilledOrRejected` throws or returns a
+  rejected promise, `$newPromise` will reject with the thrown exception or
+  rejected promise's reason.
+* If `$promise` rejects, and `$onFulfilledOrRejected` returns successfully,
+  `$newPromise` will reject with the same reason as `$promise`.
+* If `$promise` rejects, and `$onFulfilledOrRejected` throws or returns a
+  rejected promise, `$newPromise` will reject with the thrown exception or
+  rejected promise's reason.
+
+`always()` behaves similarly to the synchronous finally statement. When combined
+with `otherwise()`, `always()` allows you to write code that is similar to the familiar
+synchronous catch/finally pair.
+
+Consider the following synchronous code:
+
+```php
+try {
+  return doSomething();
+} catch(\Exception $e) {
+    return handleError($e);
+} finally {
+    cleanup();
+}
+```
+
+Similar asynchronous code (with `doSomething()` that returns a promise) can be
+written:
+
+```php
+return doSomething()
+    ->otherwise('handleError')
+    ->always('cleanup');
+```
+
+#### ExtendedPromiseInterface::progress()
+
+> Deprecated in v2.6.0: Progress support is deprecated and should not be used anymore.
+
+```php
+$promise->progress(callable $onProgress);
+```
+
+Registers a handler for progress updates from promise. It is a shortcut for:
+
+```php
+$promise->then(null, null, $onProgress);
+```
+
+### CancellablePromiseInterface
+
+A cancellable promise provides a mechanism for consumers to notify the creator
+of the promise that they are not longer interested in the result of an
+operation.
+
+#### CancellablePromiseInterface::cancel()
+
+``` php
+$promise->cancel();
+```
+
+The `cancel()` method notifies the creator of the promise that there is no
+further interest in the results of the operation.
+
+Once a promise is settled (either fulfilled or rejected), calling `cancel()` on
+a promise has no effect.
+
+#### Implementations
+
+* [Promise](#promise-1)
+* [FulfilledPromise](#fulfilledpromise)
+* [RejectedPromise](#rejectedpromise)
+* [LazyPromise](#lazypromise)
+
+### Promise
+
+Creates a promise whose state is controlled by the functions passed to
+`$resolver`.
+
+```php
+$resolver = function (callable $resolve, callable $reject, callable $notify) {
+    // Do some work, possibly asynchronously, and then
+    // resolve or reject. You can notify of progress events (deprecated)
+    // along the way if you want/need.
+
+    $resolve($awesomeResult);
+    // or throw new Exception('Promise rejected');
+    // or $resolve($anotherPromise);
+    // or $reject($nastyError);
+    // or $notify($progressNotification);
+};
+
+$canceller = function () {
+    // Cancel/abort any running operations like network connections, streams etc.
+
+    // Reject promise by throwing an exception
+    throw new Exception('Promise cancelled');
+};
+
+$promise = new React\Promise\Promise($resolver, $canceller);
+```
+
+The promise constructor receives a resolver function and an optional canceller
+function which both will be called with 3 arguments:
+
+  * `$resolve($value)` - Primary function that seals the fate of the
+    returned promise. Accepts either a non-promise value, or another promise.
+    When called with a non-promise value, fulfills promise with that value.
+    When called with another promise, e.g. `$resolve($otherPromise)`, promise's
+    fate will be equivalent to that of `$otherPromise`.
+  * `$reject($reason)` - Function that rejects the promise. It is recommended to
+    just throw an exception instead of using `$reject()`.
+  * `$notify($update)` - Deprecated function that issues progress events for the promise.
+
+If the resolver or canceller throw an exception, the promise will be rejected
+with that thrown exception as the rejection reason.
+
+The resolver function will be called immediately, the canceller function only
+once all consumers called the `cancel()` method of the promise.
+
+### FulfilledPromise
+
+Creates a already fulfilled promise.
+
+```php
+$promise = React\Promise\FulfilledPromise($value);
+```
+
+Note, that `$value` **cannot** be a promise. It's recommended to use
+[resolve()](#resolve) for creating resolved promises.
+
+### RejectedPromise
+
+Creates a already rejected promise.
+
+```php
+$promise = React\Promise\RejectedPromise($reason);
+```
+
+Note, that `$reason` **cannot** be a promise. It's recommended to use
+[reject()](#reject) for creating rejected promises.
+
+### LazyPromise
+
+Creates a promise which will be lazily initialized by `$factory` once a consumer
+calls the `then()` method.
+
+```php
+$factory = function () {
+    $deferred = new React\Promise\Deferred();
+
+    // Do some heavy stuff here and resolve the deferred once completed
+
+    return $deferred->promise();
+};
+
+$promise = new React\Promise\LazyPromise($factory);
+
+// $factory will only be executed once we call then()
+$promise->then(function ($value) {
+});
+```
+
+### Functions
+
+Useful functions for creating, joining, mapping and reducing collections of
+promises.
+
+All functions working on promise collections (like `all()`, `race()`, `some()`
+etc.) support cancellation. This means, if you call `cancel()` on the returned
+promise, all promises in the collection are cancelled. If the collection itself
+is a promise which resolves to an array, this promise is also cancelled.
+
+#### resolve()
+
+```php
+$promise = React\Promise\resolve(mixed $promiseOrValue);
+```
+
+Creates a promise for the supplied `$promiseOrValue`.
+
+If `$promiseOrValue` is a value, it will be the resolution value of the
+returned promise.
+
+If `$promiseOrValue` is a thenable (any object that provides a `then()` method),
+a trusted promise that follows the state of the thenable is returned.
+
+If `$promiseOrValue` is a promise, it will be returned as is.
+
+Note: The promise returned is always a promise implementing
+[ExtendedPromiseInterface](#extendedpromiseinterface). If you pass in a custom
+promise which only implements [PromiseInterface](#promiseinterface), this
+promise will be assimilated to a extended promise following `$promiseOrValue`.
+
+#### reject()
+
+```php
+$promise = React\Promise\reject(mixed $promiseOrValue);
+```
+
+Creates a rejected promise for the supplied `$promiseOrValue`.
+
+If `$promiseOrValue` is a value, it will be the rejection value of the
+returned promise.
+
+If `$promiseOrValue` is a promise, its completion value will be the rejected
+value of the returned promise.
+
+This can be useful in situations where you need to reject a promise without
+throwing an exception. For example, it allows you to propagate a rejection with
+the value of another promise.
+
+#### all()
+
+```php
+$promise = React\Promise\all(array|React\Promise\PromiseInterface $promisesOrValues);
+```
+
+Returns a promise that will resolve only once all the items in
+`$promisesOrValues` have resolved. The resolution value of the returned promise
+will be an array containing the resolution values of each of the items in
+`$promisesOrValues`.
+
+#### race()
+
+```php
+$promise = React\Promise\race(array|React\Promise\PromiseInterface $promisesOrValues);
+```
+
+Initiates a competitive race that allows one winner. Returns a promise which is
+resolved in the same way the first settled promise resolves.
+
+#### any()
+
+```php
+$promise = React\Promise\any(array|React\Promise\PromiseInterface $promisesOrValues);
+```
+
+Returns a promise that will resolve when any one of the items in
+`$promisesOrValues` resolves. The resolution value of the returned promise
+will be the resolution value of the triggering item.
+
+The returned promise will only reject if *all* items in `$promisesOrValues` are
+rejected. The rejection value will be an array of all rejection reasons.
+
+The returned promise will also reject with a `React\Promise\Exception\LengthException`
+if `$promisesOrValues` contains 0 items.
+
+#### some()
+
+```php
+$promise = React\Promise\some(array|React\Promise\PromiseInterface $promisesOrValues, integer $howMany);
+```
+
+Returns a promise that will resolve when `$howMany` of the supplied items in
+`$promisesOrValues` resolve. The resolution value of the returned promise
+will be an array of length `$howMany` containing the resolution values of the
+triggering items.
+
+The returned promise will reject if it becomes impossible for `$howMany` items
+to resolve (that is, when `(count($promisesOrValues) - $howMany) + 1` items
+reject). The rejection value will be an array of
+`(count($promisesOrValues) - $howMany) + 1` rejection reasons.
+
+The returned promise will also reject with a `React\Promise\Exception\LengthException`
+if `$promisesOrValues` contains less items than `$howMany`.
+
+#### map()
+
+```php
+$promise = React\Promise\map(array|React\Promise\PromiseInterface $promisesOrValues, callable $mapFunc);
+```
+
+Traditional map function, similar to `array_map()`, but allows input to contain
+promises and/or values, and `$mapFunc` may return either a value or a promise.
+
+The map function receives each item as argument, where item is a fully resolved
+value of a promise or value in `$promisesOrValues`.
+
+#### reduce()
+
+```php
+$promise = React\Promise\reduce(array|React\Promise\PromiseInterface $promisesOrValues, callable $reduceFunc , $initialValue = null);
+```
+
+Traditional reduce function, similar to `array_reduce()`, but input may contain
+promises and/or values, and `$reduceFunc` may return either a value or a
+promise, *and* `$initialValue` may be a promise or a value for the starting
+value.
+
+### PromisorInterface
+
+The `React\Promise\PromisorInterface` provides a common interface for objects
+that provide a promise. `React\Promise\Deferred` implements it, but since it
+is part of the public API anyone can implement it.
+
+Examples
+--------
+
+### How to use Deferred
+
+```php
+function getAwesomeResultPromise()
+{
+    $deferred = new React\Promise\Deferred();
+
+    // Execute a Node.js-style function using the callback pattern
+    computeAwesomeResultAsynchronously(function ($error, $result) use ($deferred) {
+        if ($error) {
+            $deferred->reject($error);
+        } else {
+            $deferred->resolve($result);
+        }
+    });
+
+    // Return the promise
+    return $deferred->promise();
+}
+
+getAwesomeResultPromise()
+    ->then(
+        function ($value) {
+            // Deferred resolved, do something with $value
+        },
+        function ($reason) {
+            // Deferred rejected, do something with $reason
+        },
+        function ($update) {
+            // Progress notification triggered, do something with $update
+        }
+    );
+```
+
+### How promise forwarding works
+
+A few simple examples to show how the mechanics of Promises/A forwarding works.
+These examples are contrived, of course, and in real usage, promise chains will
+typically be spread across several function calls, or even several levels of
+your application architecture.
+
+#### Resolution forwarding
+
+Resolved promises forward resolution values to the next promise.
+The first promise, `$deferred->promise()`, will resolve with the value passed
+to `$deferred->resolve()` below.
+
+Each call to `then()` returns a new promise that will resolve with the return
+value of the previous handler. This creates a promise "pipeline".
+
+```php
+$deferred = new React\Promise\Deferred();
+
+$deferred->promise()
+    ->then(function ($x) {
+        // $x will be the value passed to $deferred->resolve() below
+        // and returns a *new promise* for $x + 1
+        return $x + 1;
+    })
+    ->then(function ($x) {
+        // $x === 2
+        // This handler receives the return value of the
+        // previous handler.
+        return $x + 1;
+    })
+    ->then(function ($x) {
+        // $x === 3
+        // This handler receives the return value of the
+        // previous handler.
+        return $x + 1;
+    })
+    ->then(function ($x) {
+        // $x === 4
+        // This handler receives the return value of the
+        // previous handler.
+        echo 'Resolve ' . $x;
+    });
+
+$deferred->resolve(1); // Prints "Resolve 4"
+```
+
+#### Rejection forwarding
+
+Rejected promises behave similarly, and also work similarly to try/catch:
+When you catch an exception, you must rethrow for it to propagate.
+
+Similarly, when you handle a rejected promise, to propagate the rejection,
+"rethrow" it by either returning a rejected promise, or actually throwing
+(since promise translates thrown exceptions into rejections)
+
+```php
+$deferred = new React\Promise\Deferred();
+
+$deferred->promise()
+    ->then(function ($x) {
+        throw new \Exception($x + 1);
+    })
+    ->otherwise(function (\Exception $x) {
+        // Propagate the rejection
+        throw $x;
+    })
+    ->otherwise(function (\Exception $x) {
+        // Can also propagate by returning another rejection
+        return React\Promise\reject(
+            new \Exception($x->getMessage() + 1)
+        );
+    })
+    ->otherwise(function ($x) {
+        echo 'Reject ' . $x->getMessage(); // 3
+    });
+
+$deferred->resolve(1);  // Prints "Reject 3"
+```
+
+#### Mixed resolution and rejection forwarding
+
+Just like try/catch, you can choose to propagate or not. Mixing resolutions and
+rejections will still forward handler results in a predictable way.
+
+```php
+$deferred = new React\Promise\Deferred();
+
+$deferred->promise()
+    ->then(function ($x) {
+        return $x + 1;
+    })
+    ->then(function ($x) {
+        throw new \Exception($x + 1);
+    })
+    ->otherwise(function (\Exception $x) {
+        // Handle the rejection, and don't propagate.
+        // This is like catch without a rethrow
+        return $x->getMessage() + 1;
+    })
+    ->then(function ($x) {
+        echo 'Mixed ' . $x; // 4
+    });
+
+$deferred->resolve(1);  // Prints "Mixed 4"
+```
+
+#### Progress event forwarding
+
+> Deprecated in v2.6.0: Progress support is deprecated and should not be used anymore.
+
+In the same way as resolution and rejection handlers, your progress handler
+**MUST** return a progress event to be propagated to the next link in the chain.
+If you return nothing, `null` will be propagated.
+
+Also in the same way as resolutions and rejections, if you don't register a
+progress handler, the update will be propagated through.
+
+If your progress handler throws an exception, the exception will be propagated
+to the next link in the chain. The best thing to do is to ensure your progress
+handlers do not throw exceptions.
+
+This gives you the opportunity to transform progress events at each step in the
+chain so that they are meaningful to the next step. It also allows you to choose
+not to transform them, and simply let them propagate untransformed, by not
+registering a progress handler.
+
+```php
+$deferred = new React\Promise\Deferred();
+
+$deferred->promise()
+    ->progress(function ($update) {
+        return $update + 1;
+    })
+    ->progress(function ($update) {
+        echo 'Progress ' . $update; // 2
+    });
+
+$deferred->notify(1);  // Prints "Progress 2"
+```
+
+### done() vs. then()
+
+The golden rule is:
+
+    Either return your promise, or call done() on it.
+
+At a first glance, `then()` and `done()` seem very similar. However, there are
+important distinctions.
+
+The intent of `then()` is to transform a promise's value and to pass or return
+a new promise for the transformed value along to other parts of your code.
+
+The intent of `done()` is to consume a promise's value, transferring
+responsibility for the value to your code.
+
+In addition to transforming a value, `then()` allows you to recover from, or
+propagate intermediate errors. Any errors that are not handled will be caught
+by the promise machinery and used to reject the promise returned by `then()`.
+
+Calling `done()` transfers all responsibility for errors to your code. If an
+error (either a thrown exception or returned rejection) escapes the
+`$onFulfilled` or `$onRejected` callbacks you provide to done, it will be
+rethrown in an uncatchable way causing a fatal error.
+
+```php
+function getJsonResult()
+{
+    return queryApi()
+        ->then(
+            // Transform API results to an object
+            function ($jsonResultString) {
+                return json_decode($jsonResultString);
+            },
+            // Transform API errors to an exception
+            function ($jsonErrorString) {
+                $object = json_decode($jsonErrorString);
+                throw new ApiErrorException($object->errorMessage);
+            }
+        );
+}
+
+// Here we provide no rejection handler. If the promise returned has been
+// rejected, the ApiErrorException will be thrown
+getJsonResult()
+    ->done(
+        // Consume transformed object
+        function ($jsonResultObject) {
+            // Do something with $jsonResultObject
+        }
+    );
+
+// Here we provide a rejection handler which will either throw while debugging
+// or log the exception
+getJsonResult()
+    ->done(
+        function ($jsonResultObject) {
+            // Do something with $jsonResultObject
+        },
+        function (ApiErrorException $exception) {
+            if (isDebug()) {
+                throw $exception;
+            } else {
+                logException($exception);
+            }
+        }
+    );
+```
+
+Note that if a rejection value is not an instance of `\Exception`, it will be
+wrapped in an exception of the type `React\Promise\UnhandledRejectionException`.
+
+You can get the original rejection reason by calling `$exception->getReason()`.

+# Changelog
+
+## 0.8.12 (2018-06-11)
+
+*   Feature: Improve memory consumption for failed and cancelled connection attempts.
+    (#161 by @clue)
+
+*   Improve test suite to fix Travis config to test against legacy PHP 5.3 again.
+    (#162 by @clue)
+
+## 0.8.11 (2018-04-24)
+
+*   Feature: Improve memory consumption for cancelled connection attempts and
+    simplify skipping DNS lookup when connecting to IP addresses.
+    (#159 and #160 by @clue)
+
+## 0.8.10 (2018-02-28)
+
+*   Feature: Update DNS dependency to support loading system default DNS
+    nameserver config on all supported platforms
+    (`/etc/resolv.conf` on Unix/Linux/Mac/Docker/WSL and WMIC on Windows)
+    (#152 by @clue)
+
+    This means that connecting to hosts that are managed by a local DNS server,
+    such as a corporate DNS server or when using Docker containers, will now
+    work as expected across all platforms with no changes required:
+
+    ```php
+    $connector = new Connector($loop);
+    $connector->connect('intranet.example:80')->then(function ($connection) {
+        // …
+    });
+    ```
+
+## 0.8.9 (2018-01-18)
+
+*   Feature: Support explicitly choosing TLS version to negotiate with remote side
+    by respecting `crypto_method` context parameter for all classes.
+    (#149 by @clue)
+
+    By default, all connector and server classes support TLSv1.0+ and exclude
+    support for legacy SSLv2/SSLv3. As of PHP 5.6+ you can also explicitly
+    choose the TLS version you want to negotiate with the remote side:
+
+    ```php
+    // new: now supports 'crypto_method` context parameter for all classes
+    $connector = new Connector($loop, array(
+        'tls' => array(
+            'crypto_method' => STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT
+        )
+    ));
+    ```
+
+*   Minor internal clean up to unify class imports
+    (#148 by @clue)
+
+## 0.8.8 (2018-01-06)
+
+*   Improve test suite by adding test group to skip integration tests relying on
+    internet connection and fix minor documentation typo.
+    (#146 by @clue and #145 by @cn007b)
+
+## 0.8.7 (2017-12-24)
+
+*   Fix: Fix closing socket resource before removing from loop
+    (#141 by @clue)
+
+    This fixes the root cause of an uncaught `Exception` that only manifested
+    itself after the recent Stream v0.7.4 component update and only if you're
+    using `ext-event` (`ExtEventLoop`).
+
+*   Improve test suite by testing against PHP 7.2
+    (#140 by @carusogabriel)
+
+## 0.8.6 (2017-11-18)
+
+*   Feature: Add Unix domain socket (UDS) support to `Server` with `unix://` URI scheme
+    and add advanced `UnixServer` class.
+    (#120 by @andig)
+
+    ```php
+    // new: Server now supports "unix://" scheme
+    $server = new Server('unix:///tmp/server.sock', $loop);
+
+    // new: advanced usage
+    $server = new UnixServer('/tmp/server.sock', $loop);
+    ```
+
+*   Restructure examples to ease getting started
+    (#136 by @clue)
+
+*   Improve test suite by adding forward compatibility with PHPUnit 6 and
+    ignore Mac OS X test failures for now until Travis tests work again
+    (#133 by @gabriel-caruso and #134 by @clue)
+
+## 0.8.5 (2017-10-23)
+
+*   Fix: Work around PHP bug with Unix domain socket (UDS) paths for Mac OS X
+    (#123 by @andig)
+
+*   Fix: Fix `SecureServer` to return `null` URI if server socket is already closed
+    (#129 by @clue)
+
+*   Improve test suite by adding forward compatibility with PHPUnit v5 and
+    forward compatibility with upcoming EventLoop releases in tests and
+    test Mac OS X on Travis
+    (#122 by @andig and #125, #127 and #130 by @clue)
+
+*   Readme improvements
+    (#118 by @jsor)
+
+## 0.8.4 (2017-09-16)
+
+*   Feature: Add `FixedUriConnector` decorator to use fixed, preconfigured URI instead
+    (#117 by @clue)
+
+    This can be useful for consumers that do not support certain URIs, such as
+    when you want to explicitly connect to a Unix domain socket (UDS) path
+    instead of connecting to a default address assumed by an higher-level API:
+
+    ```php
+    $connector = new FixedUriConnector(
+        'unix:///var/run/docker.sock',
+        new UnixConnector($loop)
+    );
+
+    // destination will be ignored, actually connects to Unix domain socket
+    $promise = $connector->connect('localhost:80');
+    ```
+
+## 0.8.3 (2017-09-08)
+
+*   Feature: Reduce memory consumption for failed connections
+    (#113 by @valga)
+
+*   Fix: Work around write chunk size for TLS streams for PHP < 7.1.14
+    (#114 by @clue)
+
+## 0.8.2 (2017-08-25)
+
+*   Feature: Update DNS dependency to support hosts file on all platforms
+    (#112 by @clue)
+
+    This means that connecting to hosts such as `localhost` will now work as
+    expected across all platforms with no changes required:
+
+    ```php
+    $connector = new Connector($loop);
+    $connector->connect('localhost:8080')->then(function ($connection) {
+        // …
+    });
+    ```
+
+## 0.8.1 (2017-08-15)
+
+* Feature: Forward compatibility with upcoming EventLoop v1.0 and v0.5 and
+  target evenement 3.0 a long side 2.0 and 1.0
+  (#104 by @clue and #111 by @WyriHaximus)
+
+* Improve test suite by locking Travis distro so new defaults will not break the build and
+  fix HHVM build for now again and ignore future HHVM build errors
+  (#109 and #110 by @clue)
+
+* Minor documentation fixes
+  (#103 by @christiaan and #108 by @hansott)
+
+## 0.8.0 (2017-05-09)
+
+* Feature: New `Server` class now acts as a facade for existing server classes
+  and renamed old `Server` to `TcpServer` for advanced usage.
+  (#96 and #97 by @clue)
+
+  The `Server` class is now the main class in this package that implements the
+  `ServerInterface` and allows you to accept incoming streaming connections,
+  such as plaintext TCP/IP or secure TLS connection streams.
+
+  > This is not a BC break and consumer code does not have to be updated.
+
+* Feature / BC break: All addresses are now URIs that include the URI scheme
+  (#98 by @clue)
+
+  ```diff
+  - $parts = parse_url('tcp://' . $conn->getRemoteAddress());
+  + $parts = parse_url($conn->getRemoteAddress());
+  ```
+
+* Fix: Fix `unix://` addresses for Unix domain socket (UDS) paths
+  (#100 by @clue)
+
+* Feature: Forward compatibility with Stream v1.0 and v0.7
+  (#99 by @clue)
+
+## 0.7.2 (2017-04-24)
+
+* Fix: Work around latest PHP 7.0.18 and 7.1.4 no longer accepting full URIs
+  (#94 by @clue)
+
+## 0.7.1 (2017-04-10)
+
+* Fix: Ignore HHVM errors when closing connection that is already closing
+  (#91 by @clue)
+
+## 0.7.0 (2017-04-10)
+
+* Feature: Merge SocketClient component into this component
+  (#87 by @clue)
+
+  This means that this package now provides async, streaming plaintext TCP/IP
+  and secure TLS socket server and client connections for ReactPHP.
+
+  ```
+  $connector = new React\Socket\Connector($loop);
+  $connector->connect('google.com:80')->then(function (ConnectionInterface $conn) {
+      $connection->write('…');
+  });
+  ```
+
+  Accordingly, the `ConnectionInterface` is now used to represent both incoming
+  server side connections as well as outgoing client side connections.
+
+  If you've previously used the SocketClient component to establish outgoing
+  client connections, upgrading should take no longer than a few minutes.
+  All classes have been merged as-is from the latest `v0.7.0` release with no
+  other changes, so you can simply update your code to use the updated namespace
+  like this:
+
+  ```php
+  // old from SocketClient component and namespace
+  $connector = new React\SocketClient\Connector($loop);
+  $connector->connect('google.com:80')->then(function (ConnectionInterface $conn) {
+      $connection->write('…');
+  });
+
+  // new
+  $connector = new React\Socket\Connector($loop);
+  $connector->connect('google.com:80')->then(function (ConnectionInterface $conn) {
+      $connection->write('…');
+  });
+  ```
+
+## 0.6.0 (2017-04-04)
+
+* Feature: Add `LimitingServer` to limit and keep track of open connections
+  (#86 by @clue)
+
+  ```php
+  $server = new Server(0, $loop);
+  $server = new LimitingServer($server, 100);
+
+  $server->on('connection', function (ConnectionInterface $connection) {
+      $connection->write('hello there!' . PHP_EOL);
+      …
+  });
+  ```
+
+* Feature / BC break: Add `pause()` and `resume()` methods to limit active
+  connections
+  (#84 by @clue)
+
+  ```php
+  $server = new Server(0, $loop);
+  $server->pause();
+
+  $loop->addTimer(1.0, function() use ($server) {
+      $server->resume();
+  });
+  ```
+
+## 0.5.1 (2017-03-09)
+
+* Feature: Forward compatibility with Stream v0.5 and upcoming v0.6
+  (#79 by @clue)
+
+## 0.5.0 (2017-02-14)
+
+* Feature / BC break: Replace `listen()` call with URIs passed to constructor
+  and reject listening on hostnames with `InvalidArgumentException`
+  and replace `ConnectionException` with `RuntimeException` for consistency
+  (#61, #66 and #72 by @clue)
+
+  ```php
+  // old
+  $server = new Server($loop);
+  $server->listen(8080);
+
+  // new
+  $server = new Server(8080, $loop);
+  ```
+
+  Similarly, you can now pass a full listening URI to the constructor to change
+  the listening host:
+
+  ```php
+  // old
+  $server = new Server($loop);
+  $server->listen(8080, '127.0.0.1');
+
+  // new
+  $server = new Server('127.0.0.1:8080', $loop);
+  ```
+
+  Trying to start listening on (DNS) host names will now throw an
+  `InvalidArgumentException`, use IP addresses instead:
+
+  ```php
+  // old
+  $server = new Server($loop);
+  $server->listen(8080, 'localhost');
+
+  // new
+  $server = new Server('127.0.0.1:8080', $loop);
+  ```
+
+  If trying to listen fails (such as if port is already in use or port below
+  1024 may require root access etc.), it will now throw a `RuntimeException`,
+  the `ConnectionException` class has been removed:
+
+  ```php
+  // old: throws React\Socket\ConnectionException
+  $server = new Server($loop);
+  $server->listen(80);
+
+  // new: throws RuntimeException
+  $server = new Server(80, $loop);
+  ```
+
+* Feature / BC break: Rename `shutdown()` to `close()` for consistency throughout React
+  (#62 by @clue)
+
+  ```php
+  // old
+  $server->shutdown();
+
+  // new
+  $server->close();
+  ```
+
+* Feature / BC break: Replace `getPort()` with `getAddress()`
+  (#67 by @clue)
+
+  ```php
+  // old
+  echo $server->getPort(); // 8080
+
+  // new
+  echo $server->getAddress(); // 127.0.0.1:8080
+  ```
+
+* Feature / BC break: `getRemoteAddress()` returns full address instead of only IP
+  (#65 by @clue)
+
+  ```php
+  // old
+  echo $connection->getRemoteAddress(); // 192.168.0.1
+
+  // new
+  echo $connection->getRemoteAddress(); // 192.168.0.1:51743
+  ```
+  
+* Feature / BC break: Add `getLocalAddress()` method
+  (#68 by @clue)
+
+  ```php
+  echo $connection->getLocalAddress(); // 127.0.0.1:8080
+  ```
+
+* BC break: The `Server` and `SecureServer` class are now marked `final`
+  and you can no longer `extend` them
+  (which was never documented or recommended anyway).
+  Public properties and event handlers are now internal only.
+  Please use composition instead of extension.

+# Socket
+
+[![Build Status](https://travis-ci.org/reactphp/socket.svg?branch=master)](https://travis-ci.org/reactphp/socket)
+
+Async, streaming plaintext TCP/IP and secure TLS socket server and client
+connections for [ReactPHP](https://reactphp.org/).
+
+The socket library provides re-usable interfaces for a socket-layer
+server and client based on the [`EventLoop`](https://github.com/reactphp/event-loop)
+and [`Stream`](https://github.com/reactphp/stream) components.
+Its server component allows you to build networking servers that accept incoming
+connections from networking clients (such as an HTTP server).
+Its client component allows you to build networking clients that establish
+outgoing connections to networking servers (such as an HTTP or database client).
+This library provides async, streaming means for all of this, so you can
+handle multiple concurrent connections without blocking.

+## Quickstart example
+
+Here is a server that closes the connection if you send it anything:
+
+```php
+$loop = React\EventLoop\Factory::create();
+$socket = new React\Socket\Server('127.0.0.1:8080', $loop);
+
+$socket->on('connection', function (ConnectionInterface $conn) {
+    $conn->write("Hello " . $conn->getRemoteAddress() . "!\n");
+    $conn->write("Welcome to this amazing server!\n");
+    $conn->write("Here's a tip: don't say anything.\n");
+
+    $conn->on('data', function ($data) use ($conn) {
+        $conn->close();
+    });
+});
+
+$loop->run();
+```
+
+See also the [examples](examples).
+
+Here's a client that outputs the output of said server and then attempts to
+send it a string:
+
+```php
+$loop = React\EventLoop\Factory::create();
+$connector = new React\Socket\Connector($loop);
+
+$connector->connect('127.0.0.1:8080')->then(function (ConnectionInterface $conn) use ($loop) {
+    $conn->pipe(new React\Stream\WritableResourceStream(STDOUT, $loop));
+    $conn->write("Hello World!\n");
+});
+
+$loop->run();
+```
+
+## Connection usage
+
+### ConnectionInterface
+
+The `ConnectionInterface` is used to represent any incoming and outgoing
+connection, such as a normal TCP/IP connection.
+
+An incoming or outgoing connection is a duplex stream (both readable and
+writable) that implements React's
+[`DuplexStreamInterface`](https://github.com/reactphp/stream#duplexstreaminterface).
+It contains additional properties for the local and remote address (client IP)
+where this connection has been established to/from.
+
+Most commonly, instances implementing this `ConnectionInterface` are emitted
+by all classes implementing the [`ServerInterface`](#serverinterface) and
+used by all classes implementing the [`ConnectorInterface`](#connectorinterface).
+
+Because the `ConnectionInterface` implements the underlying
+[`DuplexStreamInterface`](https://github.com/reactphp/stream#duplexstreaminterface)
+you can use any of its events and methods as usual:
+
+```php
+$connection->on('data', function ($chunk) {
+    echo $chunk;
+});
+
+$connection->on('end', function () {
+    echo 'ended';
+});
+
+$connection->on('error', function (Exception $e) {
+    echo 'error: ' . $e->getMessage();
+});
+
+$connection->on('close', function () {
+    echo 'closed';
+});
+
+$connection->write($data);
+$connection->end($data = null);
+$connection->close();
+// …
+```
+
+For more details, see the
+[`DuplexStreamInterface`](https://github.com/reactphp/stream#duplexstreaminterface).
+
+#### getRemoteAddress()
+
+The `getRemoteAddress(): ?string` method returns the full remote address
+(URI) where this connection has been established with.
+
+```php
+$address = $connection->getRemoteAddress();
+echo 'Connection with ' . $address . PHP_EOL;
+```
+
+If the remote address can not be determined or is unknown at this time (such as
+after the connection has been closed), it MAY return a `NULL` value instead.
+
+Otherwise, it will return the full address (URI) as a string value, such
+as `tcp://127.0.0.1:8080`, `tcp://[::1]:80`, `tls://127.0.0.1:443`,
+`unix://example.sock` or `unix:///path/to/example.sock`.
+Note that individual URI components are application specific and depend
+on the underlying transport protocol.
+
+If this is a TCP/IP based connection and you only want the remote IP, you may
+use something like this:
+
+```php
+$address = $connection->getRemoteAddress();
+$ip = trim(parse_url($address, PHP_URL_HOST), '[]');
+echo 'Connection with ' . $ip . PHP_EOL;
+```
+
+#### getLocalAddress()
+
+The `getLocalAddress(): ?string` method returns the full local address
+(URI) where this connection has been established with.
+
+```php
+$address = $connection->getLocalAddress();
+echo 'Connection with ' . $address . PHP_EOL;
+```
+
+If the local address can not be determined or is unknown at this time (such as
+after the connection has been closed), it MAY return a `NULL` value instead.
+
+Otherwise, it will return the full address (URI) as a string value, such
+as `tcp://127.0.0.1:8080`, `tcp://[::1]:80`, `tls://127.0.0.1:443`,
+`unix://example.sock` or `unix:///path/to/example.sock`.
+Note that individual URI components are application specific and depend
+on the underlying transport protocol.
+
+This method complements the [`getRemoteAddress()`](#getremoteaddress) method,
+so they should not be confused.
+
+If your `TcpServer` instance is listening on multiple interfaces (e.g. using
+the address `0.0.0.0`), you can use this method to find out which interface
+actually accepted this connection (such as a public or local interface).
+
+If your system has multiple interfaces (e.g. a WAN and a LAN interface),
+you can use this method to find out which interface was actually
+used for this connection.
+
+## Server usage
+
+### ServerInterface
+
+The `ServerInterface` is responsible for providing an interface for accepting
+incoming streaming connections, such as a normal TCP/IP connection.
+
+Most higher-level components (such as a HTTP server) accept an instance
+implementing this interface to accept incoming streaming connections.
+This is usually done via dependency injection, so it's fairly simple to actually
+swap this implementation against any other implementation of this interface.
+This means that you SHOULD typehint against this interface instead of a concrete
+implementation of this interface.
+
+Besides defining a few methods, this interface also implements the
+[`EventEmitterInterface`](https://github.com/igorw/evenement)
+which allows you to react to certain events.
+
+#### connection event
+
+The `connection` event will be emitted whenever a new connection has been
+established, i.e. a new client connects to this server socket:
+
+```php
+$server->on('connection', function (ConnectionInterface $connection) {
+    echo 'new connection' . PHP_EOL;
+});
+```
+
+See also the [`ConnectionInterface`](#connectioninterface) for more details
+about handling the incoming connection.
+
+#### error event
+
+The `error` event will be emitted whenever there's an error accepting a new
+connection from a client.
+
+```php
+$server->on('error', function (Exception $e) {
+    echo 'error: ' . $e->getMessage() . PHP_EOL;
+});
+```
+
+Note that this is not a fatal error event, i.e. the server keeps listening for
+new connections even after this event.
+
+
+#### getAddress()
+
+The `getAddress(): ?string` method can be used to
+return the full address (URI) this server is currently listening on.
+
+```php
+$address = $server->getAddress();
+echo 'Server listening on ' . $address . PHP_EOL;
+```
+
+If the address can not be determined or is unknown at this time (such as
+after the socket has been closed), it MAY return a `NULL` value instead.
+
+Otherwise, it will return the full address (URI) as a string value, such
+as `tcp://127.0.0.1:8080`, `tcp://[::1]:80`, `tls://127.0.0.1:443`
+`unix://example.sock` or `unix:///path/to/example.sock`.
+Note that individual URI components are application specific and depend
+on the underlying transport protocol.
+
+If this is a TCP/IP based server and you only want the local port, you may
+use something like this:
+
+```php
+$address = $server->getAddress();
+$port = parse_url($address, PHP_URL_PORT);
+echo 'Server listening on port ' . $port . PHP_EOL;
+```
+
+#### pause()
+
+The `pause(): void` method can be used to
+pause accepting new incoming connections.
+
+Removes the socket resource from the EventLoop and thus stop accepting
+new connections. Note that the listening socket stays active and is not
+closed.
+
+This means that new incoming connections will stay pending in the
+operating system backlog until its configurable backlog is filled.
+Once the backlog is filled, the operating system may reject further
+incoming connections until the backlog is drained again by resuming
+to accept new connections.
+
+Once the server is paused, no futher `connection` events SHOULD
+be emitted.
+
+```php
+$server->pause();
+
+$server->on('connection', assertShouldNeverCalled());
+```
+
+This method is advisory-only, though generally not recommended, the
+server MAY continue emitting `connection` events.
+
+Unless otherwise noted, a successfully opened server SHOULD NOT start
+in paused state.
+
+You can continue processing events by calling `resume()` again.
+
+Note that both methods can be called any number of times, in particular
+calling `pause()` more than once SHOULD NOT have any effect.
+Similarly, calling this after `close()` is a NO-OP.
+
+#### resume()
+
+The `resume(): void` method can be used to
+resume accepting new incoming connections.
+
+Re-attach the socket resource to the EventLoop after a previous `pause()`.
+
+```php
+$server->pause();
+
+$loop->addTimer(1.0, function () use ($server) {
+    $server->resume();
+});
+```
+
+Note that both methods can be called any number of times, in particular
+calling `resume()` without a prior `pause()` SHOULD NOT have any effect.
+Similarly, calling this after `close()` is a NO-OP.
+
+#### close()
+
+The `close(): void` method can be used to
+shut down this listening socket.
+
+This will stop listening for new incoming connections on this socket.
+
+```php
+echo 'Shutting down server socket' . PHP_EOL;
+$server->close();
+```
+
+Calling this method more than once on the same instance is a NO-OP.
+
+### Server
+
+The `Server` class is the main class in this package that implements the
+[`ServerInterface`](#serverinterface) and allows you to accept incoming
+streaming connections, such as plaintext TCP/IP or secure TLS connection streams.
+Connections can also be accepted on Unix domain sockets.
+
+```php
+$server = new Server(8080, $loop);
+```
+
+As above, the `$uri` parameter can consist of only a port, in which case the
+server will default to listening on the localhost address `127.0.0.1`,
+which means it will not be reachable from outside of this system.
+
+In order to use a random port assignment, you can use the port `0`:
+
+```php
+$server = new Server(0, $loop);
+$address = $server->getAddress();
+```
+
+In order to change the host the socket is listening on, you can provide an IP
+address through the first parameter provided to the constructor, optionally
+preceded by the `tcp://` scheme:
+
+```php
+$server = new Server('192.168.0.1:8080', $loop);
+```
+
+If you want to listen on an IPv6 address, you MUST enclose the host in square
+brackets:
+
+```php
+$server = new Server('[::1]:8080', $loop);
+```
+
+To listen on a Unix domain socket (UDS) path, you MUST prefix the URI with the
+`unix://` scheme:
+
+```php
+$server = new Server('unix:///tmp/server.sock', $loop);
+```
+
+If the given URI is invalid, does not contain a port, any other scheme or if it
+contains a hostname, it will throw an `InvalidArgumentException`:
+
+```php
+// throws InvalidArgumentException due to missing port
+$server = new Server('127.0.0.1', $loop);
+```
+
+If the given URI appears to be valid, but listening on it fails (such as if port
+is already in use or port below 1024 may require root access etc.), it will
+throw a `RuntimeException`:
+
+```php
+$first = new Server(8080, $loop);
+
+// throws RuntimeException because port is already in use
+$second = new Server(8080, $loop);
+```
+
+> Note that these error conditions may vary depending on your system and/or
+  configuration.
+  See the exception message and code for more details about the actual error
+  condition.
+
+Optionally, you can specify [TCP socket context options](http://php.net/manual/en/context.socket.php)
+for the underlying stream socket resource like this:
+
+```php
+$server = new Server('[::1]:8080', $loop, array(
+    'tcp' => array(
+        'backlog' => 200,
+        'so_reuseport' => true,
+        'ipv6_v6only' => true
+    )
+));
+```
+
+> Note that available [socket context options](http://php.net/manual/en/context.socket.php),
+  their defaults and effects of changing these may vary depending on your system
+  and/or PHP version.
+  Passing unknown context options has no effect.
+  For BC reasons, you can also pass the TCP socket context options as a simple
+  array without wrapping this in another array under the `tcp` key.
+
+You can start a secure TLS (formerly known as SSL) server by simply prepending
+the `tls://` URI scheme.
+Internally, it will wait for plaintext TCP/IP connections and then performs a
+TLS handshake for each connection.
+It thus requires valid [TLS context options](http://php.net/manual/en/context.ssl.php),
+which in its most basic form may look something like this if you're using a
+PEM encoded certificate file:
+
+```php
+$server = new Server('tls://127.0.0.1:8080', $loop, array(
+    'tls' => array(
+        'local_cert' => 'server.pem'
+    )
+));
+```
+
+> Note that the certificate file will not be loaded on instantiation but when an
+  incoming connection initializes its TLS context.
+  This implies that any invalid certificate file paths or contents will only cause
+  an `error` event at a later time.
+
+If your private key is encrypted with a passphrase, you have to specify it
+like this:
+
+```php
+$server = new Server('tls://127.0.0.1:8000', $loop, array(
+    'tls' => array(
+        'local_cert' => 'server.pem',
+        'passphrase' => 'secret'
+    )
+));
+```
+
+By default, this server supports TLSv1.0+ and excludes support for legacy
+SSLv2/SSLv3. As of PHP 5.6+ you can also explicitly choose the TLS version you
+want to negotiate with the remote side:
+
+```php
+$server = new Server('tls://127.0.0.1:8000', $loop, array(
+    'tls' => array(
+        'local_cert' => 'server.pem',
+        'crypto_method' => STREAM_CRYPTO_METHOD_TLSv1_2_SERVER
+    )
+));
+```
+
+> Note that available [TLS context options](http://php.net/manual/en/context.ssl.php),
+  their defaults and effects of changing these may vary depending on your system
+  and/or PHP version.
+  The outer context array allows you to also use `tcp` (and possibly more)
+  context options at the same time.
+  Passing unknown context options has no effect.
+  If you do not use the `tls://` scheme, then passing `tls` context options
+  has no effect.
+
+Whenever a client connects, it will emit a `connection` event with a connection
+instance implementing [`ConnectionInterface`](#connectioninterface):
+
+```php
+$server->on('connection', function (ConnectionInterface $connection) {
+    echo 'Plaintext connection from ' . $connection->getRemoteAddress() . PHP_EOL;
+    
+    $connection->write('hello there!' . PHP_EOL);
+    …
+});
+```
+
+See also the [`ServerInterface`](#serverinterface) for more details.
+
+> Note that the `Server` class is a concrete implementation for TCP/IP sockets.
+  If you want to typehint in your higher-level protocol implementation, you SHOULD
+  use the generic [`ServerInterface`](#serverinterface) instead.
+
+### Advanced server usage
+
+#### TcpServer
+
+The `TcpServer` class implements the [`ServerInterface`](#serverinterface) and
+is responsible for accepting plaintext TCP/IP connections.
+
+```php
+$server = new TcpServer(8080, $loop);
+```
+
+As above, the `$uri` parameter can consist of only a port, in which case the

+Optionally, you can specify [socket context options](http://php.net/manual/en/context.socket.php)
+for the underlying stream socket resource like this:
+
+```php
+$server = new TcpServer('[::1]:8080', $loop, array(

+instance implementing [`ConnectionInterface`](#connectioninterface):
+
+```php
+$server->on('connection', function (ConnectionInterface $connection) {
+    echo 'Plaintext connection from ' . $connection->getRemoteAddress() . PHP_EOL;
+    
+    $connection->write('hello there!' . PHP_EOL);
+    …
+});
+```
+
+See also the [`ServerInterface`](#serverinterface) for more details.
+
+#### SecureServer
+
+The `SecureServer` class implements the [`ServerInterface`](#serverinterface)
+and is responsible for providing a secure TLS (formerly known as SSL) server.
+
+It does so by wrapping a [`TcpServer`](#tcpserver) instance which waits for plaintext
+TCP/IP connections and then performs a TLS handshake for each connection.
+It thus requires valid [TLS context options](http://php.net/manual/en/context.ssl.php),
+which in its most basic form may look something like this if you're using a
+PEM encoded certificate file:
+
+```php
+$server = new TcpServer(8000, $loop);
+$server = new SecureServer($server, $loop, array(
+    'local_cert' => 'server.pem'
+));
+```
+
+> Note that the certificate file will not be loaded on instantiation but when an
+incoming connection initializes its TLS context.
+This implies that any invalid certificate file paths or contents will only cause
+an `error` event at a later time.
+
+If your private key is encrypted with a passphrase, you have to specify it
+like this:
+
+```php
+$server = new TcpServer(8000, $loop);
+$server = new SecureServer($server, $loop, array(
+    'local_cert' => 'server.pem',
+    'passphrase' => 'secret'
+));
+```
+
+By default, this server supports TLSv1.0+ and excludes support for legacy
+SSLv2/SSLv3. As of PHP 5.6+ you can also explicitly choose the TLS version you
+want to negotiate with the remote side:
+
+```php
+$server = new TcpServer(8000, $loop);
+$server = new SecureServer($server, $loop, array(
+    'local_cert' => 'server.pem',
+    'crypto_method' => STREAM_CRYPTO_METHOD_TLSv1_2_SERVER
+));
+```
+
+> Note that available [TLS context options](http://php.net/manual/en/context.ssl.php),
+their defaults and effects of changing these may vary depending on your system
+and/or PHP version.
+Passing unknown context options has no effect.
+
+Whenever a client completes the TLS handshake, it will emit a `connection` event
+with a connection instance implementing [`ConnectionInterface`](#connectioninterface):
+
+```php
+$server->on('connection', function (ConnectionInterface $connection) {
+    echo 'Secure connection from' . $connection->getRemoteAddress() . PHP_EOL;
+    
+    $connection->write('hello there!' . PHP_EOL);
+    …
+});
+```
+
+Whenever a client fails to perform a successful TLS handshake, it will emit an
+`error` event and then close the underlying TCP/IP connection:
+
+```php
+$server->on('error', function (Exception $e) {
+    echo 'Error' . $e->getMessage() . PHP_EOL;
+});
+```
+
+See also the [`ServerInterface`](#serverinterface) for more details.
+
+Note that the `SecureServer` class is a concrete implementation for TLS sockets.
+If you want to typehint in your higher-level protocol implementation, you SHOULD
+use the generic [`ServerInterface`](#serverinterface) instead.
+
+> Advanced usage: Despite allowing any `ServerInterface` as first parameter,
+you SHOULD pass a `TcpServer` instance as first parameter, unless you
+know what you're doing.
+Internally, the `SecureServer` has to set the required TLS context options on
+the underlying stream resources.
+These resources are not exposed through any of the interfaces defined in this
+package, but only through the internal `Connection` class.
+The `TcpServer` class is guaranteed to emit connections that implement
+the `ConnectionInterface` and uses the internal `Connection` class in order to
+expose these underlying resources.
+If you use a custom `ServerInterface` and its `connection` event does not
+meet this requirement, the `SecureServer` will emit an `error` event and
+then close the underlying connection.
+
+#### UnixServer
+
+The `UnixServer` class implements the [`ServerInterface`](#serverinterface) and
+is responsible for accepting connections on Unix domain sockets (UDS).
+
+```php
+$server = new UnixServer('/tmp/server.sock', $loop);
+```
+
+As above, the `$uri` parameter can consist of only a socket path or socket path
+prefixed by the `unix://` scheme.
+
+If the given URI appears to be valid, but listening on it fails (such as if the
+socket is already in use or the file not accessible etc.), it will throw a
+`RuntimeException`:
+
+```php
+$first = new UnixServer('/tmp/same.sock', $loop);
+
+// throws RuntimeException because socket is already in use
+$second = new UnixServer('/tmp/same.sock', $loop);
+```
+
+Whenever a client connects, it will emit a `connection` event with a connection
+instance implementing [`ConnectionInterface`](#connectioninterface):
+
+```php
+$server->on('connection', function (ConnectionInterface $connection) {
+    echo 'New connection' . PHP_EOL;
+
+    $connection->write('hello there!' . PHP_EOL);
+    …
+});
+```
+
+See also the [`ServerInterface`](#serverinterface) for more details.
+
+#### LimitingServer
+
+The `LimitingServer` decorator wraps a given `ServerInterface` and is responsible
+for limiting and keeping track of open connections to this server instance.
+
+Whenever the underlying server emits a `connection` event, it will check its
+limits and then either
+ - keep track of this connection by adding it to the list of
+   open connections and then forward the `connection` event
+ - or reject (close) the connection when its limits are exceeded and will
+   forward an `error` event instead.
+
+Whenever a connection closes, it will remove this connection from the list of
+open connections.
+
+```php
+$server = new LimitingServer($server, 100);
+$server->on('connection', function (ConnectionInterface $connection) {
+    $connection->write('hello there!' . PHP_EOL);
+    …
+});
+```
+
+See also the [second example](examples) for more details.
+
+You have to pass a maximum number of open connections to ensure
+the server will automatically reject (close) connections once this limit
+is exceeded. In this case, it will emit an `error` event to inform about
+this and no `connection` event will be emitted.
+
+```php
+$server = new LimitingServer($server, 100);
+$server->on('connection', function (ConnectionInterface $connection) {
+    $connection->write('hello there!' . PHP_EOL);
+    …
+});
+```
+
+You MAY pass a `null` limit in order to put no limit on the number of
+open connections and keep accepting new connection until you run out of
+operating system resources (such as open file handles). This may be
+useful if you do not want to take care of applying a limit but still want
+to use the `getConnections()` method.
+
+You can optionally configure the server to pause accepting new
+connections once the connection limit is reached. In this case, it will
+pause the underlying server and no longer process any new connections at
+all, thus also no longer closing any excessive connections.
+The underlying operating system is responsible for keeping a backlog of
+pending connections until its limit is reached, at which point it will
+start rejecting further connections.
+Once the server is below the connection limit, it will continue consuming
+connections from the backlog and will process any outstanding data on
+each connection.
+This mode may be useful for some protocols that are designed to wait for
+a response message (such as HTTP), but may be less useful for other
+protocols that demand immediate responses (such as a "welcome" message in
+an interactive chat).
+
+```php
+$server = new LimitingServer($server, 100, true);
+$server->on('connection', function (ConnectionInterface $connection) {
+    $connection->write('hello there!' . PHP_EOL);
+    …
+});
+```
+
+##### getConnections()
+
+The `getConnections(): ConnectionInterface[]` method can be used to
+return an array with all currently active connections.
+
+```php
+foreach ($server->getConnection() as $connection) {
+    $connection->write('Hi!');
+}
+```
+
+## Client usage
+
+### ConnectorInterface
+
+The `ConnectorInterface` is responsible for providing an interface for
+establishing streaming connections, such as a normal TCP/IP connection.
+
+This is the main interface defined in this package and it is used throughout
+React's vast ecosystem.
+
+Most higher-level components (such as HTTP, database or other networking
+service clients) accept an instance implementing this interface to create their
+TCP/IP connection to the underlying networking service.
+This is usually done via dependency injection, so it's fairly simple to actually
+swap this implementation against any other implementation of this interface.
+
+The interface only offers a single method:
+
+#### connect()
+
+The `connect(string $uri): PromiseInterface<ConnectionInterface, Exception>` method
+can be used to create a streaming connection to the given remote address.
+
+It returns a [Promise](https://github.com/reactphp/promise) which either
+fulfills with a stream implementing [`ConnectionInterface`](#connectioninterface)
+on success or rejects with an `Exception` if the connection is not successful:
+
+```php
+$connector->connect('google.com:443')->then(
+    function (ConnectionInterface $connection) {
+        // connection successfully established
+    },
+    function (Exception $error) {
+        // failed to connect due to $error
+    }
+);
+```
+
+See also [`ConnectionInterface`](#connectioninterface) for more details.
+
+The returned Promise MUST be implemented in such a way that it can be
+cancelled when it is still pending. Cancelling a pending promise MUST
+reject its value with an `Exception`. It SHOULD clean up any underlying
+resources and references as applicable:
+
+```php
+$promise = $connector->connect($uri);
+
+$promise->cancel();
+```
+
+### Connector
+
+The `Connector` class is the main class in this package that implements the
+[`ConnectorInterface`](#connectorinterface) and allows you to create streaming connections.
+
+You can use this connector to create any kind of streaming connections, such
+as plaintext TCP/IP, secure TLS or local Unix connection streams.
+
+It binds to the main event loop and can be used like this:
+
+```php
+$loop = React\EventLoop\Factory::create();
+$connector = new Connector($loop);
+
+$connector->connect($uri)->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+
+$loop->run();
+```
+
+In order to create a plaintext TCP/IP connection, you can simply pass a host
+and port combination like this:
+
+```php
+$connector->connect('www.google.com:80')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+> If you do no specify a URI scheme in the destination URI, it will assume
+  `tcp://` as a default and establish a plaintext TCP/IP connection.
+  Note that TCP/IP connections require a host and port part in the destination
+  URI like above, all other URI components are optional.
+
+In order to create a secure TLS connection, you can use the `tls://` URI scheme
+like this:
+
+```php
+$connector->connect('tls://www.google.com:443')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+In order to create a local Unix domain socket connection, you can use the
+`unix://` URI scheme like this:
+
+```php
+$connector->connect('unix:///tmp/demo.sock')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+> The [`getRemoteAddress()`](#getremoteaddress) method will return the target
+  Unix domain socket (UDS) path as given to the `connect()` method, including
+  the `unix://` scheme, for example `unix:///tmp/demo.sock`.
+  The [`getLocalAddress()`](#getlocaladdress) method will most likely return a
+  `null` value as this value is not applicable to UDS connections here.
+
+Under the hood, the `Connector` is implemented as a *higher-level facade*
+for the lower-level connectors implemented in this package. This means it
+also shares all of their features and implementation details.
+If you want to typehint in your higher-level protocol implementation, you SHOULD
+use the generic [`ConnectorInterface`](#connectorinterface) instead.
+
+The `Connector` class will try to detect your system DNS settings (and uses
+Google's public DNS server `8.8.8.8` as a fallback if unable to determine your
+system settings) to resolve all public hostnames into underlying IP addresses by
+default.
+If you explicitly want to use a custom DNS server (such as a local DNS relay or
+a company wide DNS server), you can set up the `Connector` like this:
+
+```php
+$connector = new Connector($loop, array(
+    'dns' => '127.0.1.1'
+));
+
+$connector->connect('localhost:80')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+If you do not want to use a DNS resolver at all and want to connect to IP
+addresses only, you can also set up your `Connector` like this:
+
+```php
+$connector = new Connector($loop, array(
+    'dns' => false
+));
+
+$connector->connect('127.0.0.1:80')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+Advanced: If you need a custom DNS `Resolver` instance, you can also set up
+your `Connector` like this:
+
+```php
+$dnsResolverFactory = new React\Dns\Resolver\Factory();
+$resolver = $dnsResolverFactory->createCached('127.0.1.1', $loop);
+
+$connector = new Connector($loop, array(
+    'dns' => $resolver
+));
+
+$connector->connect('localhost:80')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+By default, the `tcp://` and `tls://` URI schemes will use timeout value that
+repects your `default_socket_timeout` ini setting (which defaults to 60s).
+If you want a custom timeout value, you can simply pass this like this:
+
+```php
+$connector = new Connector($loop, array(
+    'timeout' => 10.0
+));
+```
+
+Similarly, if you do not want to apply a timeout at all and let the operating
+system handle this, you can pass a boolean flag like this:
+
+```php
+$connector = new Connector($loop, array(
+    'timeout' => false
+));
+```
+
+By default, the `Connector` supports the `tcp://`, `tls://` and `unix://`
+URI schemes. If you want to explicitly prohibit any of these, you can simply
+pass boolean flags like this:
+
+```php
+// only allow secure TLS connections
+$connector = new Connector($loop, array(
+    'tcp' => false,
+    'tls' => true,
+    'unix' => false,
+));
+
+$connector->connect('tls://google.com:443')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+The `tcp://` and `tls://` also accept additional context options passed to
+the underlying connectors.
+If you want to explicitly pass additional context options, you can simply
+pass arrays of context options like this:
+
+```php
+// allow insecure TLS connections
+$connector = new Connector($loop, array(
+    'tcp' => array(
+        'bindto' => '192.168.0.1:0'
+    ),
+    'tls' => array(
+        'verify_peer' => false,
+        'verify_peer_name' => false
+    ),
+));
+
+$connector->connect('tls://localhost:443')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+By default, this connector supports TLSv1.0+ and excludes support for legacy
+SSLv2/SSLv3. As of PHP 5.6+ you can also explicitly choose the TLS version you
+want to negotiate with the remote side:
+
+```php
+$connector = new Connector($loop, array(
+    'tls' => array(
+        'crypto_method' => STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT
+    )
+));
+```
+
+> For more details about context options, please refer to the PHP documentation
+  about [socket context options](http://php.net/manual/en/context.socket.php)
+  and [SSL context options](http://php.net/manual/en/context.ssl.php).
+
+Advanced: By default, the `Connector` supports the `tcp://`, `tls://` and
+`unix://` URI schemes.
+For this, it sets up the required connector classes automatically.
+If you want to explicitly pass custom connectors for any of these, you can simply
+pass an instance implementing the `ConnectorInterface` like this:
+
+```php
+$dnsResolverFactory = new React\Dns\Resolver\Factory();
+$resolver = $dnsResolverFactory->createCached('127.0.1.1', $loop);
+$tcp = new DnsConnector(new TcpConnector($loop), $resolver);
+
+$tls = new SecureConnector($tcp, $loop);
+
+$unix = new UnixConnector($loop);
+
+$connector = new Connector($loop, array(
+    'tcp' => $tcp,
+    'tls' => $tls,
+    'unix' => $unix,
+
+    'dns' => false,
+    'timeout' => false,
+));
+
+$connector->connect('google.com:80')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+> Internally, the `tcp://` connector will always be wrapped by the DNS resolver,
+  unless you disable DNS like in the above example. In this case, the `tcp://`
+  connector receives the actual hostname instead of only the resolved IP address
+  and is thus responsible for performing the lookup.
+  Internally, the automatically created `tls://` connector will always wrap the
+  underlying `tcp://` connector for establishing the underlying plaintext
+  TCP/IP connection before enabling secure TLS mode. If you want to use a custom
+  underlying `tcp://` connector for secure TLS connections only, you may
+  explicitly pass a `tls://` connector like above instead.
+  Internally, the `tcp://` and `tls://` connectors will always be wrapped by
+  `TimeoutConnector`, unless you disable timeouts like in the above example.
+
+### Advanced client usage
+
+#### TcpConnector
+
+The `React\Socket\TcpConnector` class implements the
+[`ConnectorInterface`](#connectorinterface) and allows you to create plaintext
+TCP/IP connections to any IP-port-combination:
+
+```php
+$tcpConnector = new React\Socket\TcpConnector($loop);
+
+$tcpConnector->connect('127.0.0.1:80')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+
+$loop->run();
+```
+
+See also the [examples](examples).
+
+Pending connection attempts can be cancelled by cancelling its pending promise like so:
+
+```php
+$promise = $tcpConnector->connect('127.0.0.1:80');
+
+$promise->cancel();
+```
+
+Calling `cancel()` on a pending promise will close the underlying socket
+resource, thus cancelling the pending TCP/IP connection, and reject the
+resulting promise.
+
+You can optionally pass additional
+[socket context options](http://php.net/manual/en/context.socket.php)
+to the constructor like this:
+
+```php
+$tcpConnector = new React\Socket\TcpConnector($loop, array(
+    'bindto' => '192.168.0.1:0'
+));
+```
+
+Note that this class only allows you to connect to IP-port-combinations.
+If the given URI is invalid, does not contain a valid IP address and port
+or contains any other scheme, it will reject with an
+`InvalidArgumentException`:
+
+If the given URI appears to be valid, but connecting to it fails (such as if
+the remote host rejects the connection etc.), it will reject with a
+`RuntimeException`.
+
+If you want to connect to hostname-port-combinations, see also the following chapter.
+
+> Advanced usage: Internally, the `TcpConnector` allocates an empty *context*
+resource for each stream resource.
+If the destination URI contains a `hostname` query parameter, its value will
+be used to set up the TLS peer name.
+This is used by the `SecureConnector` and `DnsConnector` to verify the peer
+name and can also be used if you want a custom TLS peer name.
+
+#### DnsConnector
+
+The `DnsConnector` class implements the
+[`ConnectorInterface`](#connectorinterface) and allows you to create plaintext
+TCP/IP connections to any hostname-port-combination.
+
+It does so by decorating a given `TcpConnector` instance so that it first
+looks up the given domain name via DNS (if applicable) and then establishes the
+underlying TCP/IP connection to the resolved target IP address.
+
+Make sure to set up your DNS resolver and underlying TCP connector like this:
+
+```php
+$dnsResolverFactory = new React\Dns\Resolver\Factory();
+$dns = $dnsResolverFactory->createCached('8.8.8.8', $loop);
+
+$dnsConnector = new React\Socket\DnsConnector($tcpConnector, $dns);
+
+$dnsConnector->connect('www.google.com:80')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+
+$loop->run();
+```
+
+See also the [examples](examples).
+
+Pending connection attempts can be cancelled by cancelling its pending promise like so:
+
+```php
+$promise = $dnsConnector->connect('www.google.com:80');
+
+$promise->cancel();
+```
+
+Calling `cancel()` on a pending promise will cancel the underlying DNS lookup
+and/or the underlying TCP/IP connection and reject the resulting promise.
+
+> Advanced usage: Internally, the `DnsConnector` relies on a `Resolver` to
+look up the IP address for the given hostname.
+It will then replace the hostname in the destination URI with this IP and
+append a `hostname` query parameter and pass this updated URI to the underlying
+connector.
+The underlying connector is thus responsible for creating a connection to the
+target IP address, while this query parameter can be used to check the original
+hostname and is used by the `TcpConnector` to set up the TLS peer name.
+If a `hostname` is given explicitly, this query parameter will not be modified,
+which can be useful if you want a custom TLS peer name.
+
+#### SecureConnector
+
+The `SecureConnector` class implements the
+[`ConnectorInterface`](#connectorinterface) and allows you to create secure
+TLS (formerly known as SSL) connections to any hostname-port-combination.
+
+It does so by decorating a given `DnsConnector` instance so that it first
+creates a plaintext TCP/IP connection and then enables TLS encryption on this
+stream.
+
+```php
+$secureConnector = new React\Socket\SecureConnector($dnsConnector, $loop);
+
+$secureConnector->connect('www.google.com:443')->then(function (ConnectionInterface $connection) {
+    $connection->write("GET / HTTP/1.0\r\nHost: www.google.com\r\n\r\n");
+    ...
+});
+
+$loop->run();
+```
+
+See also the [examples](examples).
+
+Pending connection attempts can be cancelled by cancelling its pending promise like so:
+
+```php
+$promise = $secureConnector->connect('www.google.com:443');
+
+$promise->cancel();
+```
+
+Calling `cancel()` on a pending promise will cancel the underlying TCP/IP
+connection and/or the SSL/TLS negotiation and reject the resulting promise.
+
+You can optionally pass additional
+[SSL context options](http://php.net/manual/en/context.ssl.php)
+to the constructor like this:
+
+```php
+$secureConnector = new React\Socket\SecureConnector($dnsConnector, $loop, array(
+    'verify_peer' => false,
+    'verify_peer_name' => false
+));
+```
+
+By default, this connector supports TLSv1.0+ and excludes support for legacy
+SSLv2/SSLv3. As of PHP 5.6+ you can also explicitly choose the TLS version you
+want to negotiate with the remote side:
+
+```php
+$secureConnector = new React\Socket\SecureConnector($dnsConnector, $loop, array(
+    'crypto_method' => STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT
+));
+```
+
+> Advanced usage: Internally, the `SecureConnector` relies on setting up the
+required *context options* on the underlying stream resource.
+It should therefor be used with a `TcpConnector` somewhere in the connector
+stack so that it can allocate an empty *context* resource for each stream
+resource and verify the peer name.
+Failing to do so may result in a TLS peer name mismatch error or some hard to
+trace race conditions, because all stream resources will use a single, shared
+*default context* resource otherwise.
+
+#### TimeoutConnector
+
+The `TimeoutConnector` class implements the
+[`ConnectorInterface`](#connectorinterface) and allows you to add timeout
+handling to any existing connector instance.
+
+It does so by decorating any given [`ConnectorInterface`](#connectorinterface)
+instance and starting a timer that will automatically reject and abort any
+underlying connection attempt if it takes too long.
+
+```php
+$timeoutConnector = new React\Socket\TimeoutConnector($connector, 3.0, $loop);
+
+$timeoutConnector->connect('google.com:80')->then(function (ConnectionInterface $connection) {
+    // connection succeeded within 3.0 seconds
+});
+```
+
+See also any of the [examples](examples).
+
+Pending connection attempts can be cancelled by cancelling its pending promise like so:
+
+```php
+$promise = $timeoutConnector->connect('google.com:80');
+
+$promise->cancel();
+```
+
+Calling `cancel()` on a pending promise will cancel the underlying connection
+attempt, abort the timer and reject the resulting promise.
+
+#### UnixConnector
+
+The `UnixConnector` class implements the
+[`ConnectorInterface`](#connectorinterface) and allows you to connect to
+Unix domain socket (UDS) paths like this:
+
+```php
+$connector = new React\Socket\UnixConnector($loop);
+
+$connector->connect('/tmp/demo.sock')->then(function (ConnectionInterface $connection) {
+    $connection->write("HELLO\n");
+});
+
+$loop->run();
+```
+
+Connecting to Unix domain sockets is an atomic operation, i.e. its promise will
+settle (either resolve or reject) immediately.
+As such, calling `cancel()` on the resulting promise has no effect.
+
+> The [`getRemoteAddress()`](#getremoteaddress) method will return the target
+  Unix domain socket (UDS) path as given to the `connect()` method, prepended
+  with the `unix://` scheme, for example `unix:///tmp/demo.sock`.
+  The [`getLocalAddress()`](#getlocaladdress) method will most likely return a
+  `null` value as this value is not applicable to UDS connections here.
+
+#### FixedUriConnector
+
+The `FixedUriConnector` class implements the
+[`ConnectorInterface`](#connectorinterface) and decorates an existing Connector
+to always use a fixed, preconfigured URI.
+
+This can be useful for consumers that do not support certain URIs, such as
+when you want to explicitly connect to a Unix domain socket (UDS) path
+instead of connecting to a default address assumed by an higher-level API:
+
+```php
+$connector = new FixedUriConnector(
+    'unix:///var/run/docker.sock',
+    new UnixConnector($loop)
+);
+
+// destination will be ignored, actually connects to Unix domain socket
+$promise = $connector->connect('localhost:80');
+```
+
+## Install
+
+The recommended way to install this library is [through Composer](https://getcomposer.org).
+[New to Composer?](https://getcomposer.org/doc/00-intro.md)
+
+This will install the latest supported version:
+
+```bash
+$ composer require react/socket:^0.8.12
+```
+
+See also the [CHANGELOG](CHANGELOG.md) for details about version upgrades.
+
+This project aims to run on any platform and thus does not require any PHP
+extensions and supports running on legacy PHP 5.3 through current PHP 7+ and HHVM.
+It's *highly recommended to use PHP 7+* for this project, partly due to its vast
+performance improvements and partly because legacy PHP versions require several
+workarounds as described below.
+
+Secure TLS connections received some major upgrades starting with PHP 5.6, with
+the defaults now being more secure, while older versions required explicit
+context options.
+This library does not take responsibility over these context options, so it's
+up to consumers of this library to take care of setting appropriate context
+options as described above.
+
+All versions of PHP prior to 5.6.8 suffered from a buffering issue where reading
+from a streaming TLS connection could be one `data` event behind.
+This library implements a work-around to try to flush the complete incoming
+data buffers on these legacy PHP versions, which has a penalty of around 10% of
+throughput on all connections.
+With this work-around, we have not been able to reproduce this issue anymore,
+but we have seen reports of people saying this could still affect some of the
+older PHP versions (`5.5.23`, `5.6.7`, and `5.6.8`).
+Note that this only affects *some* higher-level streaming protocols, such as
+IRC over TLS, but should not affect HTTP over TLS (HTTPS).
+Further investigation of this issue is needed.
+For more insights, this issue is also covered by our test suite.
+
+PHP < 7.1.4 (and PHP < 7.0.18) suffers from a bug when writing big
+chunks of data over TLS streams at once.
+We try to work around this by limiting the write chunk size to 8192
+bytes for older PHP versions only.
+This is only a work-around and has a noticable performance penalty on
+affected versions.
+
+This project also supports running on HHVM.
+Note that really old HHVM < 3.8 does not support secure TLS connections, as it
+lacks the required `stream_socket_enable_crypto()` function.
+As such, trying to create a secure TLS connections on affected versions will
+return a rejected promise instead.
+This issue is also covered by our test suite, which will skip related tests
+on affected versions.
+
+## Tests
+
+To run the test suite, you first need to clone this repo and then install all
+dependencies [through Composer](https://getcomposer.org):
+
+```bash
+$ composer install
+```
+
+To run the test suite, go to the project root and run:
+
+```bash
+$ php vendor/bin/phpunit
+```
+
+The test suite also contains a number of functional integration tests that rely
+on a stable internet connection.
+If you do not want to run these, they can simply be skipped like this:
+
+```bash
+$ php vendor/bin/phpunit --exclude-group internet
+```

+     * It does so by wrapping a `TcpServer` instance which waits for plaintext

+     * It thus requires valid [TLS context options],
+     * which in its most basic form may look something like this if you're using a
+     * PEM encoded certificate file:
+     *
+     * ```php

+     * incoming connection initializes its TLS context.
+     * This implies that any invalid certificate file paths or contents will only cause
+     * an `error` event at a later time.
+     *
+     * If your private key is encrypted with a passphrase, you have to specify it
+     * like this:
+     *
+     * ```php
+     * $server = new TcpServer(8000, $loop);

+     *     'passphrase' => 'secret'
+     * ));
+     * ```
+     *
+     * Note that available [TLS context options],
+     * their defaults and effects of changing these may vary depending on your system
+     * and/or PHP version.
+     * Passing unknown context options has no effect.
+     *
+     * Advanced usage: Despite allowing any `ServerInterface` as first parameter,
+     * you SHOULD pass a `TcpServer` instance as first parameter, unless you
+     * know what you're doing.
+     * Internally, the `SecureServer` has to set the required TLS context options on
+     * the underlying stream resources.
+     * These resources are not exposed through any of the interfaces defined in this
+     * package, but only through the internal `Connection` class.
+     * The `TcpServer` class is guaranteed to emit connections that implement
+     * the `ConnectionInterface` and uses the internal `Connection` class in order to
+     * expose these underlying resources.

+/**
+ * The `ServerInterface` is responsible for providing an interface for accepting
+ * incoming streaming connections, such as a normal TCP/IP connection.
+ *
+ * Most higher-level components (such as a HTTP server) accept an instance
+ * implementing this interface to accept incoming streaming connections.
+ * This is usually done via dependency injection, so it's fairly simple to actually
+ * swap this implementation against any other implementation of this interface.
+ * This means that you SHOULD typehint against this interface instead of a concrete
+ * implementation of this interface.
+ *
+ * Besides defining a few methods, this interface also implements the
+ * `EventEmitterInterface` which allows you to react to certain events:
+ *
+ * connection event:
+ *     The `connection` event will be emitted whenever a new connection has been
+ *     established, i.e. a new client connects to this server socket:
+ *
+ *     ```php
+ *     $server->on('connection', function (ConnectionInterface $connection) {
+ *         echo 'new connection' . PHP_EOL;
+ *     });
+ *     ```
+ *
+ *     See also the `ConnectionInterface` for more details about handling the
+ *     incoming connection.
+ *
+ * error event:
+ *     The `error` event will be emitted whenever there's an error accepting a new
+ *     connection from a client.
+ *
+ *     ```php
+ *     $server->on('error', function (Exception $e) {
+ *         echo 'error: ' . $e->getMessage() . PHP_EOL;
+ *     });
+ *     ```
+ *
+ *     Note that this is not a fatal error event, i.e. the server keeps listening for
+ *     new connections even after this event.
+ *
+ * @see ConnectionInterface

+     * Note that individual URI components are application specific and depend
+     * on the underlying transport protocol.

+     * As above, the `$uri` parameter can consist of only a port, in which case the
+     * server will default to listening on the localhost address `127.0.0.1`,
+     * which means it will not be reachable from outside of this system.
+     *
+     * In order to use a random port assignment, you can use the port `0`:

+     * $address = $server->getAddress();
+     * ```

+     * address through the first parameter provided to the constructor, optionally

+     *
+     * ```php
+     * $server = new TcpServer('192.168.0.1:8080', $loop);
+     * ```

+     * brackets:
+     *
+     * ```php
+     * $server = new TcpServer('[::1]:8080', $loop);
+     * ```
+     *
+     * If the given URI is invalid, does not contain a port, any other scheme or if it
+     * contains a hostname, it will throw an `InvalidArgumentException`:
+     *
+     * ```php
+     * // throws InvalidArgumentException due to missing port
+     * $server = new TcpServer('127.0.0.1', $loop);
+     * ```
+     *
+     * If the given URI appears to be valid, but listening on it fails (such as if port
+     * is already in use or port below 1024 may require root access etc.), it will
+     * throw a `RuntimeException`:
+     *
+     * ```php
+     * $first = new TcpServer(8080, $loop);
+     *
+     * // throws RuntimeException because port is already in use
+     * $second = new TcpServer(8080, $loop);

+     * configuration.
+     * See the exception message and code for more details about the actual error
+     * condition.
+     *
+     * Optionally, you can specify [socket context options](http://php.net/manual/en/context.socket.php)
+     * for the underlying stream socket resource like this:
+     *
+     * ```php
+     * $server = new TcpServer('[::1]:8080', $loop, array(
+     *     'backlog' => 200,
+     *     'so_reuseport' => true,
+     *     'ipv6_v6only' => true
+     * ));
+     * ```
+     *
+     * Note that available [socket context options](http://php.net/manual/en/context.socket.php),
+     * their defaults and effects of changing these may vary depending on your system

+    (#113 by @docteurklein and #114 and #115 by @clue)
+
+*   Improve test suite by running against Mac OS X on Travis

+
+*   Feature: Add optional `$writeChunkSize` parameter to limit maximum number of
+    bytes to write at once.
+    (#105 by @clue)
+
+    ```php
+    $stream = new WritableResourceStream(STDOUT, $loop, null, 8192);
+    ```
+
+*   Ignore HHVM test failures for now until Travis tests work again
+    (#106 by @clue)
+
+## 0.7.0 (2017-05-04)
+
+*   Removed / BC break: Remove deprecated and unneeded functionality
+    (#45, #87, #90, #91 and #93 by @clue)
+
+    *   Remove deprecated `Stream` class, use `DuplexResourceStream` instead
+        (#87 by @clue)
+      
+    *   Remove public `$buffer` property, use new constructor parameters instead
+        (#91 by @clue)
+
+    *   Remove public `$stream` property from all resource streams
+        (#90 by @clue)
+
+    *   Remove undocumented and now unused `ReadableStream` and `WritableStream`
+        (#93 by @clue)
+
+    *   Remove `BufferedSink`
+        (#45 by @clue)
+
+*   Feature / BC break: Simplify `ThroughStream` by using data callback instead of
+    inheritance. It is now a direct implementation of `DuplexStreamInterface`.
+    (#88 and #89 by @clue)
+
+    ```php
+    $through = new ThroughStream(function ($data) {
+        return json_encode($data) . PHP_EOL;
+    });
+    $through->on('data', $this->expectCallableOnceWith("[2, true]\n"));
+
+    $through->write(array(2, true));
+    ```
+
+*   Feature / BC break: The `CompositeStream` starts closed if either side is
+    already closed and forwards pause to pipe source on first write attempt.
+    (#96 and #103 by @clue)
+    
+    If either side of the composite stream closes, it will also close the other
+    side. We now also ensure that if either side is already closed during
+    instantiation, it will also close the other side.
+
+*   BC break: Mark all classes as `final` and
+    mark internal API as `private` to discourage inheritance
+    (#95 and #99 by @clue)
+
+*   Feature / BC break: Only emit `error` event for fatal errors
+    (#92 by @clue)
+
+    >   The `error` event was previously also allowed to be emitted for non-fatal
+        errors, but our implementations actually only ever emitted this as a fatal
+        error and then closed the stream.
+
+*   Feature: Explicitly allow custom events and exclude any semantics
+    (#97 by @clue)
+
+*   Strict definition for event callback functions
+    (#101 by @clue)
+
+*   Support legacy PHP 5.3 through PHP 7.1 and HHVM and improve usage documentation
+    (#100 and #102 by @clue)
+
+*   Actually require all dependencies so this is self-contained and improve
+    forward compatibility with EventLoop v1.0 and v0.5
+    (#94 and #98 by @clue)
+
+## 0.6.0 (2017-03-26)
+
+* Feature / Fix / BC break: Add `DuplexResourceStream` and deprecate `Stream`
+  (#85 by @clue)
+
+  ```php
+  // old (does still work for BC reasons)
+  $stream = new Stream($connection, $loop);
+
+  // new
+  $stream = new DuplexResourceStream($connection, $loop);
+  ```
+
+  Note that the `DuplexResourceStream` now rejects read-only or write-only
+  streams, so this may affect BC. If you want a read-only or write-only
+  resource, use `ReadableResourceStream` or `WritableResourceStream` instead of
+  `DuplexResourceStream`.
+
+  > BC note: This class was previously called `Stream`. The `Stream` class still
+    exists for BC reasons and will be removed in future versions of this package.
+
+* Feature / BC break: Add `WritableResourceStream` (previously called `Buffer`)
+  (#84 by @clue)
+
+  ```php
+  // old
+  $stream = new Buffer(STDOUT, $loop);
+
+  // new
+  $stream = new WritableResourceStream(STDOUT, $loop);
+  ```
+
+* Feature: Add `ReadableResourceStream`
+  (#83 by @clue)
+
+  ```php
+  $stream = new ReadableResourceStream(STDIN, $loop);
+  ```
+
+* Fix / BC Break: Enforce using non-blocking I/O
+  (#46 by @clue)
+
+  > BC note: This is known to affect process pipes on Windows which do not
+    support non-blocking I/O and could thus block the whole EventLoop previously.
+
+* Feature / Fix / BC break: Consistent semantics for
+  `DuplexStreamInterface::end()` to ensure it SHOULD also end readable side
+  (#86 by @clue)
+
+* Fix: Do not use unbuffered reads on pipe streams for legacy PHP < 5.4
+  (#80 by @clue)
+
+## 0.5.0 (2017-03-08)
+
+* Feature / BC break: Consistent `end` event semantics (EOF)
+  (#70 by @clue)
+  
+  The `end` event will now only be emitted for a *successful* end, not if the
+  stream closes due to an unrecoverable `error` event or if you call `close()`
+  explicitly.
+  If you want to detect when the stream closes (terminates), use the `close`
+  event instead.
+
+* BC break: Remove custom (undocumented) `full-drain` event from `Buffer`
+  (#63 and #68 by @clue)
+
+  > The `full-drain` event was undocumented and mostly used internally.
+    Relying on this event has attracted some low-quality code in the past, so
+    we've removed this from the public API in order to work out a better
+    solution instead.
+    If you want to detect when the buffer finishes flushing data to the stream,
+    you may want to look into its `end()` method or the `close` event instead.
+
+* Feature / BC break: Consistent event semantics and documentation,
+  explicitly state *when* events will be emitted and *which* arguments they
+  receive.
+  (#73 and #69 by @clue)
+
+  The documentation now explicitly defines each event and its arguments.
+  Custom events and event arguments are still supported.
+  Most notably, all defined events only receive inherently required event
+  arguments and no longer transmit the instance they are emitted on for
+  consistency and performance reasons.
+
+  ```php
+  // old (inconsistent and not supported by all implementations)
+  $stream->on('data', function ($data, $stream) {
+      // process $data
+  });
+
+  // new (consistent throughout the whole ecosystem)
+  $stream->on('data', function ($data) use ($stream) {
+      // process $data
+  });
+  ```
+
+  > This mostly adds documentation (and thus some stricter, consistent 
+    definitions) for the existing behavior, it does NOT define any major
+    changes otherwise.
+    Most existing code should be compatible with these changes, unless
+    it relied on some undocumented/unintended semantics.
+
+* Feature / BC break: Consistent method semantics and documentation
+  (#72 by @clue)
+
+  > This mostly adds documentation (and thus some stricter, consistent
+    definitions) for the existing behavior, it does NOT define any major
+    changes otherwise.
+    Most existing code should be compatible with these changes, unless
+    it relied on some undocumented/unintended semantics.
+
+* Feature: Consistent `pipe()` semantics for closed and closing streams
+  (#71 from @clue)
+
+  The source stream will now always be paused via `pause()` when the
+  destination stream closes. Also, properly stop piping if the source
+  stream closes and remove all event forwarding.
+
+* Improve test suite by adding PHPUnit to `require-dev` and improving coverage.
+  (#74 and #75 by @clue, #66 by @nawarian)
+
+## 0.4.6 (2017-01-25)
+
+* Feature: The `Buffer` can now be injected into the `Stream` (or be used standalone)
+  (#62 by @clue)
+
+* Fix: Forward `close` event only once for `CompositeStream` and `ThroughStream`
+  (#60 by @clue)
+
+* Fix: Consistent `close` event behavior for `Buffer`
+  (#61 by @clue)
+
+## 0.4.5 (2016-11-13)
+
+* Feature: Support setting read buffer size to `null` (infinite)
+  (#42 by @clue)
+
+* Fix: Do not emit `full-drain` event if `Buffer` is closed during `drain` event
+  (#55 by @clue)
+
+* Vastly improved performance by factor of 10x to 20x.
+  Raise default buffer sizes to 64 KiB and simplify and improve error handling
+  and unneeded function calls.
+  (#53, #55, #56 by @clue)
+
+## 0.4.4 (2016-08-22)
+
+* Bug fix: Emit `error` event and close `Stream` when accessing the underlying
+  stream resource fails with a permanent error.
+  (#52 and #40 by @clue, #25 by @lysenkobv)
+
+* Bug fix: Do not emit empty `data` event if nothing has been read (stream reached EOF)
+  (#39 by @clue)
+
+* Bug fix: Ignore empty writes to `Buffer`
+  (#51 by @clue)
+
+* Add benchmarking script to measure throughput in CI
+  (#41 by @clue)

+# Stream
+
+[![Build Status](https://travis-ci.org/reactphp/stream.svg?branch=master)](https://travis-ci.org/reactphp/stream)
+
+Event-driven readable and writable streams for non-blocking I/O in [ReactPHP](https://reactphp.org/).
+
+In order to make the [EventLoop](https://github.com/reactphp/event-loop)
+easier to use, this component introduces the powerful concept of "streams".
+Streams allow you to efficiently process huge amounts of data (such as a multi
+Gigabyte file download) in small chunks without having to store everything in
+memory at once.
+They are very similar to the streams found in PHP itself,
+but have an interface more suited for async, non-blocking I/O.

+## Stream usage
+
+ReactPHP uses the concept of "streams" throughout its ecosystem to provide a
+consistent higher-level abstraction for processing streams of arbitrary data
+contents and size.
+While a stream itself is a quite low-level concept, it can be used as a powerful
+abstraction to build higher-level components and protocols on top.
+
+If you're new to this concept, it helps to think of them as a water pipe:
+You can consume water from a source or you can produce water and forward (pipe)
+it to any destination (sink).
+
+Similarly, streams can either be
+
+* readable (such as `STDIN` terminal input) or
+* writable (such as `STDOUT` terminal output) or
+* duplex (both readable *and* writable, such as a TCP/IP connection)
+
+Accordingly, this package defines the following three interfaces
+
+* [`ReadableStreamInterface`](#readablestreaminterface)
+* [`WritableStreamInterface`](#writablestreaminterface)
+* [`DuplexStreamInterface`](#duplexstreaminterface)
+
+### ReadableStreamInterface
+
+The `ReadableStreamInterface` is responsible for providing an interface for
+read-only streams and the readable side of duplex streams.
+
+Besides defining a few methods, this interface also implements the
+`EventEmitterInterface` which allows you to react to certain events.
+
+The event callback functions MUST be a valid `callable` that obeys strict
+parameter definitions and MUST accept event parameters exactly as documented.
+The event callback functions MUST NOT throw an `Exception`.
+The return value of the event callback functions will be ignored and has no
+effect, so for performance reasons you're recommended to not return any
+excessive data structures.
+
+Every implementation of this interface MUST follow these event semantics in
+order to be considered a well-behaving stream.
+
+> Note that higher-level implementations of this interface may choose to
+  define additional events with dedicated semantics not defined as part of
+  this low-level stream specification. Conformance with these event semantics
+  is out of scope for this interface, so you may also have to refer to the
+  documentation of such a higher-level implementation.
+
+#### data event
+
+The `data` event will be emitted whenever some data was read/received
+from this source stream.
+The event receives a single mixed argument for incoming data.
+
+```php
+$stream->on('data', function ($data) {
+    echo $data;
+});
+```
+
+This event MAY be emitted any number of times, which may be zero times if
+this stream does not send any data at all.
+It SHOULD not be emitted after an `end` or `close` event.
+
+The given `$data` argument may be of mixed type, but it's usually
+recommended it SHOULD be a `string` value or MAY use a type that allows
+representation as a `string` for maximum compatibility.
+
+Many common streams (such as a TCP/IP connection or a file-based stream)
+will emit the raw (binary) payload data that is received over the wire as
+chunks of `string` values.
+
+Due to the stream-based nature of this, the sender may send any number
+of chunks with varying sizes. There are no guarantees that these chunks
+will be received with the exact same framing the sender intended to send.
+In other words, many lower-level protocols (such as TCP/IP) transfer the
+data in chunks that may be anywhere between single-byte values to several
+dozens of kilobytes. You may want to apply a higher-level protocol to
+these low-level data chunks in order to achieve proper message framing.
+  
+#### end event
+
+The `end` event will be emitted once the source stream has successfully
+reached the end of the stream (EOF).
+
+```php
+$stream->on('end', function () {
+    echo 'END';
+});
+```
+
+This event SHOULD be emitted once or never at all, depending on whether
+a successful end was detected.
+It SHOULD NOT be emitted after a previous `end` or `close` event.
+It MUST NOT be emitted if the stream closes due to a non-successful
+end, such as after a previous `error` event.
+
+After the stream is ended, it MUST switch to non-readable mode,
+see also `isReadable()`.
+
+This event will only be emitted if the *end* was reached successfully,
+not if the stream was interrupted by an unrecoverable error or explicitly
+closed. Not all streams know this concept of a "successful end".
+Many use-cases involve detecting when the stream closes (terminates)
+instead, in this case you should use the `close` event.
+After the stream emits an `end` event, it SHOULD usually be followed by a
+`close` event.
+
+Many common streams (such as a TCP/IP connection or a file-based stream)
+will emit this event if either the remote side closes the connection or
+a file handle was successfully read until reaching its end (EOF).
+
+Note that this event should not be confused with the `end()` method.
+This event defines a successful end *reading* from a source stream, while
+the `end()` method defines *writing* a successful end to a destination
+stream.
+
+#### error event
+
+The `error` event will be emitted once a fatal error occurs, usually while
+trying to read from this stream.
+The event receives a single `Exception` argument for the error instance.
+
+```php
+$server->on('error', function (Exception $e) {
+    echo 'Error: ' . $e->getMessage() . PHP_EOL;
+});
+```
+
+This event SHOULD be emitted once the stream detects a fatal error, such
+as a fatal transmission error or after an unexpected `data` or premature
+`end` event.
+It SHOULD NOT be emitted after a previous `error`, `end` or `close` event.
+It MUST NOT be emitted if this is not a fatal error condition, such as
+a temporary network issue that did not cause any data to be lost.
+
+After the stream errors, it MUST close the stream and SHOULD thus be
+followed by a `close` event and then switch to non-readable mode, see
+also `close()` and `isReadable()`.
+
+Many common streams (such as a TCP/IP connection or a file-based stream)
+only deal with data transmission and do not make assumption about data
+boundaries (such as unexpected `data` or premature `end` events).
+In other words, many lower-level protocols (such as TCP/IP) may choose
+to only emit this for a fatal transmission error once and will then
+close (terminate) the stream in response.
+
+If this stream is a `DuplexStreamInterface`, you should also notice
+how the writable side of the stream also implements an `error` event.
+In other words, an error may occur while either reading or writing the
+stream which should result in the same error processing.
+
+#### close event
+
+The `close` event will be emitted once the stream closes (terminates).
+
+```php
+$stream->on('close', function () {
+    echo 'CLOSED';
+});
+```
+
+This event SHOULD be emitted once or never at all, depending on whether
+the stream ever terminates.
+It SHOULD NOT be emitted after a previous `close` event.
+
+After the stream is closed, it MUST switch to non-readable mode,
+see also `isReadable()`.
+
+Unlike the `end` event, this event SHOULD be emitted whenever the stream
+closes, irrespective of whether this happens implicitly due to an
+unrecoverable error or explicitly when either side closes the stream.
+If you only want to detect a *successful* end, you should use the `end`
+event instead.
+
+Many common streams (such as a TCP/IP connection or a file-based stream)
+will likely choose to emit this event after reading a *successful* `end`
+event or after a fatal transmission `error` event.
+
+If this stream is a `DuplexStreamInterface`, you should also notice
+how the writable side of the stream also implements a `close` event.
+In other words, after receiving this event, the stream MUST switch into
+non-writable AND non-readable mode, see also `isWritable()`.
+Note that this event should not be confused with the `end` event.
+
+#### isReadable()
+
+The `isReadable(): bool` method can be used to
+check whether this stream is in a readable state (not closed already).
+
+This method can be used to check if the stream still accepts incoming
+data events or if it is ended or closed already.
+Once the stream is non-readable, no further `data` or `end` events SHOULD
+be emitted.
+
+```php
+assert($stream->isReadable() === false);
+
+$stream->on('data', assertNeverCalled());
+$stream->on('end', assertNeverCalled());
+```
+
+A successfully opened stream always MUST start in readable mode.
+
+Once the stream ends or closes, it MUST switch to non-readable mode.
+This can happen any time, explicitly through `close()` or
+implicitly due to a remote close or an unrecoverable transmission error.
+Once a stream has switched to non-readable mode, it MUST NOT transition
+back to readable mode.
+
+If this stream is a `DuplexStreamInterface`, you should also notice
+how the writable side of the stream also implements an `isWritable()`
+method. Unless this is a half-open duplex stream, they SHOULD usually
+have the same return value.
+
+#### pause()
+
+The `pause(): void` method can be used to
+pause reading incoming data events.
+
+Removes the data source file descriptor from the event loop. This
+allows you to throttle incoming data.
+
+Unless otherwise noted, a successfully opened stream SHOULD NOT start
+in paused state.
+
+Once the stream is paused, no futher `data` or `end` events SHOULD
+be emitted.
+
+```php
+$stream->pause();
+
+$stream->on('data', assertShouldNeverCalled());
+$stream->on('end', assertShouldNeverCalled());
+```
+
+This method is advisory-only, though generally not recommended, the
+stream MAY continue emitting `data` events.
+
+You can continue processing events by calling `resume()` again.
+
+Note that both methods can be called any number of times, in particular
+calling `pause()` more than once SHOULD NOT have any effect.
+
+See also `resume()`.
+
+#### resume()
+
+The `resume(): void` method can be used to
+resume reading incoming data events.
+
+Re-attach the data source after a previous `pause()`.
+
+```php
+$stream->pause();
+
+$loop->addTimer(1.0, function () use ($stream) {
+    $stream->resume();
+});
+```
+
+Note that both methods can be called any number of times, in particular
+calling `resume()` without a prior `pause()` SHOULD NOT have any effect.
+ 
+See also `pause()`.
+
+#### pipe()
+
+The `pipe(WritableStreamInterface $dest, array $options = [])` method can be used to
+pipe all the data from this readable source into the given writable destination.
+
+Automatically sends all incoming data to the destination.
+Automatically throttles the source based on what the destination can handle.
+
+```php
+$source->pipe($dest);
+```
+
+Similarly, you can also pipe an instance implementing `DuplexStreamInterface`
+into itself in order to write back all the data that is received.
+This may be a useful feature for a TCP/IP echo service:
+
+```php
+$connection->pipe($connection);
+```
+
+This method returns the destination stream as-is, which can be used to
+set up chains of piped streams:
+
+```php
+$source->pipe($decodeGzip)->pipe($filterBadWords)->pipe($dest);
+```
+
+By default, this will call `end()` on the destination stream once the
+source stream emits an `end` event. This can be disabled like this:
+
+```php
+$source->pipe($dest, array('end' => false));
+```
+
+Note that this only applies to the `end` event.
+If an `error` or explicit `close` event happens on the source stream,
+you'll have to manually close the destination stream:
+
+```php
+$source->pipe($dest);
+$source->on('close', function () use ($dest) {
+    $dest->end('BYE!');
+});
+```
+
+If the source stream is not readable (closed state), then this is a NO-OP.
+
+```php
+$source->close();
+$source->pipe($dest); // NO-OP
+```
+
+If the destinantion stream is not writable (closed state), then this will simply
+throttle (pause) the source stream:
+
+```php
+$dest->close();
+$source->pipe($dest); // calls $source->pause()
+```
+
+Similarly, if the destination stream is closed while the pipe is still
+active, it will also throttle (pause) the source stream:
+
+```php
+$source->pipe($dest);
+$dest->close(); // calls $source->pause()
+```
+
+Once the pipe is set up successfully, the destination stream MUST emit
+a `pipe` event with this source stream an event argument.
+
+#### close()
+
+The `close(): void` method can be used to
+close the stream (forcefully).
+
+This method can be used to (forcefully) close the stream.
+
+```php
+$stream->close();
+```
+
+Once the stream is closed, it SHOULD emit a `close` event.
+Note that this event SHOULD NOT be emitted more than once, in particular
+if this method is called multiple times.
+
+After calling this method, the stream MUST switch into a non-readable
+mode, see also `isReadable()`.
+This means that no further `data` or `end` events SHOULD be emitted.
+
+```php
+$stream->close();
+assert($stream->isReadable() === false);
+
+$stream->on('data', assertNeverCalled());
+$stream->on('end', assertNeverCalled());
+```
+
+If this stream is a `DuplexStreamInterface`, you should also notice
+how the writable side of the stream also implements a `close()` method.
+In other words, after calling this method, the stream MUST switch into
+non-writable AND non-readable mode, see also `isWritable()`.
+Note that this method should not be confused with the `end()` method.
+
+### WritableStreamInterface
+
+The `WritableStreamInterface` is responsible for providing an interface for
+write-only streams and the writable side of duplex streams.
+
+Besides defining a few methods, this interface also implements the
+`EventEmitterInterface` which allows you to react to certain events.
+
+The event callback functions MUST be a valid `callable` that obeys strict
+parameter definitions and MUST accept event parameters exactly as documented.
+The event callback functions MUST NOT throw an `Exception`.
+The return value of the event callback functions will be ignored and has no
+effect, so for performance reasons you're recommended to not return any
+excessive data structures.
+
+Every implementation of this interface MUST follow these event semantics in
+order to be considered a well-behaving stream.
+
+> Note that higher-level implementations of this interface may choose to
+  define additional events with dedicated semantics not defined as part of
+  this low-level stream specification. Conformance with these event semantics
+  is out of scope for this interface, so you may also have to refer to the
+  documentation of such a higher-level implementation.
+
+#### drain event
+
+The `drain` event will be emitted whenever the write buffer became full
+previously and is now ready to accept more data.
+
+```php
+$stream->on('drain', function () use ($stream) {
+    echo 'Stream is now ready to accept more data';
+});
+```
+
+This event SHOULD be emitted once every time the buffer became full
+previously and is now ready to accept more data.
+In other words, this event MAY be emitted any number of times, which may
+be zero times if the buffer never became full in the first place.
+This event SHOULD NOT be emitted if the buffer has not become full
+previously.
+
+This event is mostly used internally, see also `write()` for more details.
+
+#### pipe event
+
+The `pipe` event will be emitted whenever a readable stream is `pipe()`d
+into this stream.
+The event receives a single `ReadableStreamInterface` argument for the
+source stream.
+
+```php
+$stream->on('pipe', function (ReadableStreamInterface $source) use ($stream) {
+    echo 'Now receiving piped data';
+
+    // explicitly close target if source emits an error
+    $source->on('error', function () use ($stream) {
+        $stream->close();
+    });
+});
+
+$source->pipe($stream);
+```
+
+This event MUST be emitted once for each readable stream that is
+successfully piped into this destination stream.
+In other words, this event MAY be emitted any number of times, which may
+be zero times if no stream is ever piped into this stream.
+This event MUST NOT be emitted if either the source is not readable
+(closed already) or this destination is not writable (closed already).
+
+This event is mostly used internally, see also `pipe()` for more details.
+
+#### error event
+
+The `error` event will be emitted once a fatal error occurs, usually while
+trying to write to this stream.
+The event receives a single `Exception` argument for the error instance.
+
+```php
+$stream->on('error', function (Exception $e) {
+    echo 'Error: ' . $e->getMessage() . PHP_EOL;
+});
+```
+
+This event SHOULD be emitted once the stream detects a fatal error, such
+as a fatal transmission error.
+It SHOULD NOT be emitted after a previous `error` or `close` event.
+It MUST NOT be emitted if this is not a fatal error condition, such as
+a temporary network issue that did not cause any data to be lost.
+
+After the stream errors, it MUST close the stream and SHOULD thus be
+followed by a `close` event and then switch to non-writable mode, see
+also `close()` and `isWritable()`.
+
+Many common streams (such as a TCP/IP connection or a file-based stream)
+only deal with data transmission and may choose
+to only emit this for a fatal transmission error once and will then
+close (terminate) the stream in response.
+
+If this stream is a `DuplexStreamInterface`, you should also notice
+how the readable side of the stream also implements an `error` event.
+In other words, an error may occur while either reading or writing the
+stream which should result in the same error processing.
+
+#### close event
+
+The `close` event will be emitted once the stream closes (terminates).
+
+```php
+$stream->on('close', function () {
+    echo 'CLOSED';
+});
+```
+
+This event SHOULD be emitted once or never at all, depending on whether
+the stream ever terminates.
+It SHOULD NOT be emitted after a previous `close` event.
+
+After the stream is closed, it MUST switch to non-writable mode,
+see also `isWritable()`.
+
+This event SHOULD be emitted whenever the stream closes, irrespective of
+whether this happens implicitly due to an unrecoverable error or
+explicitly when either side closes the stream.
+
+Many common streams (such as a TCP/IP connection or a file-based stream)
+will likely choose to emit this event after flushing the buffer from
+the `end()` method, after receiving a *successful* `end` event or after
+a fatal transmission `error` event.
+
+If this stream is a `DuplexStreamInterface`, you should also notice
+how the readable side of the stream also implements a `close` event.
+In other words, after receiving this event, the stream MUST switch into
+non-writable AND non-readable mode, see also `isReadable()`.
+Note that this event should not be confused with the `end` event.
+
+#### isWritable()
+
+The `isWritable(): bool` method can be used to
+check whether this stream is in a writable state (not closed already).
+
+This method can be used to check if the stream still accepts writing
+any data or if it is ended or closed already.
+Writing any data to a non-writable stream is a NO-OP:
+
+```php
+assert($stream->isWritable() === false);
+
+$stream->write('end'); // NO-OP
+$stream->end('end'); // NO-OP
+```
+
+A successfully opened stream always MUST start in writable mode.
+
+Once the stream ends or closes, it MUST switch to non-writable mode.
+This can happen any time, explicitly through `end()` or `close()` or
+implicitly due to a remote close or an unrecoverable transmission error.
+Once a stream has switched to non-writable mode, it MUST NOT transition
+back to writable mode.
+
+If this stream is a `DuplexStreamInterface`, you should also notice
+how the readable side of the stream also implements an `isReadable()`
+method. Unless this is a half-open duplex stream, they SHOULD usually
+have the same return value.
+
+#### write()
+
+The `write(mixed $data): bool` method can be used to
+write some data into the stream.
+
+A successful write MUST be confirmed with a boolean `true`, which means
+that either the data was written (flushed) immediately or is buffered and
+scheduled for a future write. Note that this interface gives you no
+control over explicitly flushing the buffered data, as finding the
+appropriate time for this is beyond the scope of this interface and left
+up to the implementation of this interface.
+
+Many common streams (such as a TCP/IP connection or file-based stream)
+may choose to buffer all given data and schedule a future flush by using
+an underlying EventLoop to check when the resource is actually writable.
+
+If a stream cannot handle writing (or flushing) the data, it SHOULD emit
+an `error` event and MAY `close()` the stream if it can not recover from
+this error.
+
+If the internal buffer is full after adding `$data`, then `write()`
+SHOULD return `false`, indicating that the caller should stop sending
+data until the buffer drains.
+The stream SHOULD send a `drain` event once the buffer is ready to accept
+more data.
+
+Similarly, if the the stream is not writable (already in a closed state)
+it MUST NOT process the given `$data` and SHOULD return `false`,
+indicating that the caller should stop sending data.
+
+The given `$data` argument MAY be of mixed type, but it's usually
+recommended it SHOULD be a `string` value or MAY use a type that allows
+representation as a `string` for maximum compatibility.
+
+Many common streams (such as a TCP/IP connection or a file-based stream)
+will only accept the raw (binary) payload data that is transferred over
+the wire as chunks of `string` values.
+
+Due to the stream-based nature of this, the sender may send any number
+of chunks with varying sizes. There are no guarantees that these chunks
+will be received with the exact same framing the sender intended to send.
+In other words, many lower-level protocols (such as TCP/IP) transfer the
+data in chunks that may be anywhere between single-byte values to several
+dozens of kilobytes. You may want to apply a higher-level protocol to
+these low-level data chunks in order to achieve proper message framing.
+
+#### end()
+
+The `end(mixed $data = null): void` method can be used to
+successfully end the stream (after optionally sending some final data).
+
+This method can be used to successfully end the stream, i.e. close
+the stream after sending out all data that is currently buffered.
+
+```php
+$stream->write('hello');
+$stream->write('world');
+$stream->end();
+```
+
+If there's no data currently buffered and nothing to be flushed, then
+this method MAY `close()` the stream immediately.
+
+If there's still data in the buffer that needs to be flushed first, then
+this method SHOULD try to write out this data and only then `close()`
+the stream.
+Once the stream is closed, it SHOULD emit a `close` event.
+
+Note that this interface gives you no control over explicitly flushing
+the buffered data, as finding the appropriate time for this is beyond the
+scope of this interface and left up to the implementation of this
+interface.
+
+Many common streams (such as a TCP/IP connection or file-based stream)
+may choose to buffer all given data and schedule a future flush by using
+an underlying EventLoop to check when the resource is actually writable.
+
+You can optionally pass some final data that is written to the stream
+before ending the stream. If a non-`null` value is given as `$data`, then
+this method will behave just like calling `write($data)` before ending
+with no data.
+
+```php
+// shorter version
+$stream->end('bye');
+
+// same as longer version
+$stream->write('bye');
+$stream->end();
+```
+
+After calling this method, the stream MUST switch into a non-writable
+mode, see also `isWritable()`.
+This means that no further writes are possible, so any additional
+`write()` or `end()` calls have no effect.
+
+```php
+$stream->end();
+assert($stream->isWritable() === false);
+
+$stream->write('nope'); // NO-OP
+$stream->end(); // NO-OP
+```
+
+If this stream is a `DuplexStreamInterface`, calling this method SHOULD
+also end its readable side, unless the stream supports half-open mode.
+In other words, after calling this method, these streams SHOULD switch
+into non-writable AND non-readable mode, see also `isReadable()`.
+This implies that in this case, the stream SHOULD NOT emit any `data`
+or `end` events anymore.
+Streams MAY choose to use the `pause()` method logic for this, but
+special care may have to be taken to ensure a following call to the
+`resume()` method SHOULD NOT continue emitting readable events.
+
+Note that this method should not be confused with the `close()` method.
+
+#### close()
+
+The `close(): void` method can be used to
+close the stream (forcefully).
+
+This method can be used to forcefully close the stream, i.e. close
+the stream without waiting for any buffered data to be flushed.
+If there's still data in the buffer, this data SHOULD be discarded.
+
+```php
+$stream->close();
+```
+
+Once the stream is closed, it SHOULD emit a `close` event.
+Note that this event SHOULD NOT be emitted more than once, in particular
+if this method is called multiple times.
+
+After calling this method, the stream MUST switch into a non-writable
+mode, see also `isWritable()`.
+This means that no further writes are possible, so any additional
+`write()` or `end()` calls have no effect.
+
+```php
+$stream->close();
+assert($stream->isWritable() === false);
+
+$stream->write('nope'); // NO-OP
+$stream->end(); // NO-OP
+```
+
+Note that this method should not be confused with the `end()` method.
+Unlike the `end()` method, this method does not take care of any existing
+buffers and simply discards any buffer contents.
+Likewise, this method may also be called after calling `end()` on a
+stream in order to stop waiting for the stream to flush its final data.
+
+```php
+$stream->end();
+$loop->addTimer(1.0, function () use ($stream) {
+    $stream->close();
+});
+```
+
+If this stream is a `DuplexStreamInterface`, you should also notice
+how the readable side of the stream also implements a `close()` method.
+In other words, after calling this method, the stream MUST switch into
+non-writable AND non-readable mode, see also `isReadable()`.
+
+### DuplexStreamInterface
+
+The `DuplexStreamInterface` is responsible for providing an interface for
+duplex streams (both readable and writable).
+
+It builds on top of the existing interfaces for readable and writable streams
+and follows the exact same method and event semantics.
+If you're new to this concept, you should look into the
+`ReadableStreamInterface` and `WritableStreamInterface` first.
+
+Besides defining a few methods, this interface also implements the
+`EventEmitterInterface` which allows you to react to the same events defined
+on the `ReadbleStreamInterface` and `WritableStreamInterface`.
+
+The event callback functions MUST be a valid `callable` that obeys strict
+parameter definitions and MUST accept event parameters exactly as documented.
+The event callback functions MUST NOT throw an `Exception`.
+The return value of the event callback functions will be ignored and has no
+effect, so for performance reasons you're recommended to not return any
+excessive data structures.
+
+Every implementation of this interface MUST follow these event semantics in
+order to be considered a well-behaving stream.
+
+> Note that higher-level implementations of this interface may choose to
+  define additional events with dedicated semantics not defined as part of
+  this low-level stream specification. Conformance with these event semantics
+  is out of scope for this interface, so you may also have to refer to the
+  documentation of such a higher-level implementation.
+
+See also [`ReadableStreamInterface`](#readablestreaminterface) and
+[`WritableStreamInterface`](#writablestreaminterface) for more details.
+
+## Creating streams
+
+ReactPHP uses the concept of "streams" throughout its ecosystem, so that
+many higher-level consumers of this package only deal with
+[stream usage](#stream-usage).
+This implies that stream instances are most often created within some
+higher-level components and many consumers never actually have to deal with
+creating a stream instance.
+
+* Use [react/socket](https://github.com/reactphp/socket)
+  if you want to accept incoming or establish outgoing plaintext TCP/IP or
+  secure TLS socket connection streams.
+* Use [react/http](https://github.com/reactphp/http)
+  if you want to receive an incoming HTTP request body streams.
+* Use [react/child-process](https://github.com/reactphp/child-process)
+  if you want to communicate with child processes via process pipes such as
+  STDIN, STDOUT, STDERR etc.
+* Use experimental [react/filesystem](https://github.com/reactphp/filesystem)
+  if you want to read from / write to the filesystem.
+* See also the last chapter for [more real-world applications](#more).
+
+However, if you are writing a lower-level component or want to create a stream
+instance from a stream resource, then the following chapter is for you.
+
+> Note that the following examples use `fopen()` and `stream_socket_client()`
+  for illustration purposes only.
+  These functions SHOULD NOT be used in a truly async program because each call
+  may take several seconds to complete and would block the EventLoop otherwise.
+  Additionally, the `fopen()` call will return a file handle on some platforms
+  which may or may not be supported by all EventLoop implementations.
+  As an alternative, you may want to use higher-level libraries listed above.
+
+### ReadableResourceStream
+
+The `ReadableResourceStream` is a concrete implementation of the
+[`ReadableStreamInterface`](#readablestreaminterface) for PHP's stream resources.
+
+This can be used to represent a read-only resource like a file stream opened in
+readable mode or a stream such as `STDIN`:
+
+```php
+$stream = new ReadableResourceStream(STDIN, $loop);
+$stream->on('data', function ($chunk) {
+    echo $chunk;
+});
+$stream->on('end', function () {
+    echo 'END';
+});
+```
+
+See also [`ReadableStreamInterface`](#readablestreaminterface) for more details.
+
+The first parameter given to the constructor MUST be a valid stream resource
+that is opened in reading mode (e.g. `fopen()` mode `r`).
+Otherwise, it will throw an `InvalidArgumentException`:
+
+```php
+// throws InvalidArgumentException
+$stream = new ReadableResourceStream(false, $loop);
+```
+
+See also the [`DuplexResourceStream`](#readableresourcestream) for read-and-write
+stream resources otherwise.
+
+Internally, this class tries to enable non-blocking mode on the stream resource
+which may not be supported for all stream resources.
+Most notably, this is not supported by pipes on Windows (STDIN etc.).
+If this fails, it will throw a `RuntimeException`:
+
+```php
+// throws RuntimeException on Windows
+$stream = new ReadableResourceStream(STDIN, $loop);
+```
+
+Once the constructor is called with a valid stream resource, this class will
+take care of the underlying stream resource.
+You SHOULD only use its public API and SHOULD NOT interfere with the underlying
+stream resource manually.
+
+This class takes an optional `int|null $readChunkSize` parameter that controls
+the maximum buffer size in bytes to read at once from the stream.
+You can use a `null` value here in order to apply its default value.
+This value SHOULD NOT be changed unless you know what you're doing.
+This can be a positive number which means that up to X bytes will be read
+at once from the underlying stream resource. Note that the actual number
+of bytes read may be lower if the stream resource has less than X bytes
+currently available.
+This can be `-1` which means "read everything available" from the
+underlying stream resource.
+This should read until the stream resource is not readable anymore
+(i.e. underlying buffer drained), note that this does not neccessarily
+mean it reached EOF.
+
+```php
+$stream = new ReadableResourceStream(STDIN, $loop, 8192);
+```
+
+> PHP bug warning: If the PHP process has explicitly been started without a
+  `STDIN` stream, then trying to read from `STDIN` may return data from
+  another stream resource. This does not happen if you start this with an empty
+  stream like `php test.php < /dev/null` instead of `php test.php <&-`.
+  See [#81](https://github.com/reactphp/stream/issues/81) for more details.
+
+### WritableResourceStream
+
+The `WritableResourceStream` is a concrete implementation of the
+[`WritableStreamInterface`](#writablestreaminterface) for PHP's stream resources.
+
+This can be used to represent a write-only resource like a file stream opened in
+writable mode or a stream such as `STDOUT` or `STDERR`:
+
+```php
+$stream = new WritableResourceStream(STDOUT, $loop);
+$stream->write('hello!');
+$stream->end();
+```
+
+See also [`WritableStreamInterface`](#writablestreaminterface) for more details.
+
+The first parameter given to the constructor MUST be a valid stream resource
+that is opened for writing.
+Otherwise, it will throw an `InvalidArgumentException`:
+
+```php
+// throws InvalidArgumentException
+$stream = new WritableResourceStream(false, $loop);
+```
+
+See also the [`DuplexResourceStream`](#readableresourcestream) for read-and-write
+stream resources otherwise.
+
+Internally, this class tries to enable non-blocking mode on the stream resource
+which may not be supported for all stream resources.
+Most notably, this is not supported by pipes on Windows (STDOUT, STDERR etc.).
+If this fails, it will throw a `RuntimeException`:
+
+```php
+// throws RuntimeException on Windows
+$stream = new WritableResourceStream(STDOUT, $loop);
+```
+
+Once the constructor is called with a valid stream resource, this class will
+take care of the underlying stream resource.
+You SHOULD only use its public API and SHOULD NOT interfere with the underlying
+stream resource manually.
+
+Any `write()` calls to this class will not be performed instantly, but will
+be performed asynchronously, once the EventLoop reports the stream resource is
+ready to accept data.
+For this, it uses an in-memory buffer string to collect all outstanding writes.
+This buffer has a soft-limit applied which defines how much data it is willing
+to accept before the caller SHOULD stop sending further data.
+
+This class takes an optional `int|null $writeBufferSoftLimit` parameter that controls
+this maximum buffer size in bytes.
+You can use a `null` value here in order to apply its default value.
+This value SHOULD NOT be changed unless you know what you're doing.
+
+```php
+$stream = new WritableResourceStream(STDOUT, $loop, 8192);
+```
+
+This class takes an optional `int|null $writeChunkSize` parameter that controls
+this maximum buffer size in bytes to write at once to the stream.
+You can use a `null` value here in order to apply its default value.
+This value SHOULD NOT be changed unless you know what you're doing.
+This can be a positive number which means that up to X bytes will be written
+at once to the underlying stream resource. Note that the actual number
+of bytes written may be lower if the stream resource has less than X bytes
+currently available.
+This can be `-1` which means "write everything available" to the
+underlying stream resource.
+
+```php
+$stream = new WritableResourceStream(STDOUT, $loop, null, 8192);
+```
+
+See also [`write()`](#write) for more details.
+
+### DuplexResourceStream
+
+The `DuplexResourceStream` is a concrete implementation of the
+[`DuplexStreamInterface`](#duplexstreaminterface) for PHP's stream resources.
+
+This can be used to represent a read-and-write resource like a file stream opened
+in read and write mode mode or a stream such as a TCP/IP connection:
+
+```php
+$conn = stream_socket_client('tcp://google.com:80');
+$stream = new DuplexResourceStream($conn, $loop);
+$stream->write('hello!');
+$stream->end();
+```
+
+See also [`DuplexStreamInterface`](#duplexstreaminterface) for more details.
+
+The first parameter given to the constructor MUST be a valid stream resource
+that is opened for reading *and* writing.
+Otherwise, it will throw an `InvalidArgumentException`:
+
+```php
+// throws InvalidArgumentException
+$stream = new DuplexResourceStream(false, $loop);
+```
+
+See also the [`ReadableResourceStream`](#readableresourcestream) for read-only
+and the [`WritableResourceStream`](#writableresourcestream) for write-only
+stream resources otherwise.
+
+Internally, this class tries to enable non-blocking mode on the stream resource
+which may not be supported for all stream resources.
+Most notably, this is not supported by pipes on Windows (STDOUT, STDERR etc.).
+If this fails, it will throw a `RuntimeException`:
+
+```php
+// throws RuntimeException on Windows
+$stream = new DuplexResourceStream(STDOUT, $loop);
+```
+
+Once the constructor is called with a valid stream resource, this class will
+take care of the underlying stream resource.
+You SHOULD only use its public API and SHOULD NOT interfere with the underlying
+stream resource manually.
+
+This class takes an optional `int|null $readChunkSize` parameter that controls
+the maximum buffer size in bytes to read at once from the stream.
+You can use a `null` value here in order to apply its default value.
+This value SHOULD NOT be changed unless you know what you're doing.
+This can be a positive number which means that up to X bytes will be read
+at once from the underlying stream resource. Note that the actual number
+of bytes read may be lower if the stream resource has less than X bytes
+currently available.
+This can be `-1` which means "read everything available" from the
+underlying stream resource.
+This should read until the stream resource is not readable anymore
+(i.e. underlying buffer drained), note that this does not neccessarily
+mean it reached EOF.
+
+```php
+$conn = stream_socket_client('tcp://google.com:80');
+$stream = new DuplexResourceStream($conn, $loop, 8192);
+```
+
+Any `write()` calls to this class will not be performed instantly, but will
+be performed asynchronously, once the EventLoop reports the stream resource is
+ready to accept data.
+For this, it uses an in-memory buffer string to collect all outstanding writes.
+This buffer has a soft-limit applied which defines how much data it is willing
+to accept before the caller SHOULD stop sending further data.
+
+This class takes another optional `WritableStreamInterface|null $buffer` parameter
+that controls this write behavior of this stream.
+You can use a `null` value here in order to apply its default value.
+This value SHOULD NOT be changed unless you know what you're doing.
+
+If you want to change the write buffer soft limit, you can pass an instance of
+[`WritableResourceStream`](#writableresourcestream) like this:
+
+```php
+$conn = stream_socket_client('tcp://google.com:80');
+$buffer = new WritableResourceStream($conn, $loop, 8192);
+$stream = new DuplexResourceStream($conn, $loop, null, $buffer);
+```
+
+See also [`WritableResourceStream`](#writableresourcestream) for more details.
+
+### ThroughStream
+
+The `ThroughStream` implements the
+[`DuplexStreamInterface`](#duplexstreaminterface) and will simply pass any data
+you write to it through to its readable end.
+
+```php
+$through = new ThroughStream();
+$through->on('data', $this->expectCallableOnceWith('hello'));
+
+$through->write('hello');
+```
+
+Similarly, the [`end()` method](#end) will end the stream and emit an
+[`end` event](#end-event) and then [`close()`](#close-1) the stream.
+The [`close()` method](#close-1) will close the stream and emit a
+[`close` event](#close-event).
+Accordingly, this is can also be used in a [`pipe()`](#pipe) context like this:
+
+```php
+$through = new ThroughStream();
+$source->pipe($through)->pipe($dest);
+```
+
+Optionally, its constructor accepts any callable function which will then be
+used to *filter* any data written to it. This function receives a single data
+argument as passed to the writable side and must return the data as it will be
+passed to its readable end:
+
+```php
+$through = new ThroughStream('strtoupper');
+$source->pipe($through)->pipe($dest);
+```
+
+Note that this class makes no assumptions about any data types. This can be
+used to convert data, for example for transforming any structured data into
+a newline-delimited JSON (NDJSON) stream like this:
+
+```php
+$through = new ThroughStream(function ($data) {
+    return json_encode($data) . PHP_EOL;
+});
+$through->on('data', $this->expectCallableOnceWith("[2, true]\n"));
+
+$through->write(array(2, true));
+```
+
+The callback function is allowed to throw an `Exception`. In this case,
+the stream will emit an `error` event and then [`close()`](#close-1) the stream.
+
+```php
+$through = new ThroughStream(function ($data) {
+    if (!is_string($data)) {
+        throw new \UnexpectedValueException('Only strings allowed');
+    }
+    return $data;
+});
+$through->on('error', $this->expectCallableOnce()));
+$through->on('close', $this->expectCallableOnce()));
+$through->on('data', $this->expectCallableNever()));
+
+$through->write(2);
+```
+
+### CompositeStream
+
+The `CompositeStream` implements the
+[`DuplexStreamInterface`](#duplexstreaminterface) and can be used to create a
+single duplex stream from two individual streams implementing
+[`ReadableStreamInterface`](#readablestreaminterface) and
+[`WritableStreamInterface`](#writablestreaminterface) respectively.
+
+This is useful for some APIs which may require a single
+[`DuplexStreamInterface`](#duplexstreaminterface) or simply because it's often
+more convenient to work with a single stream instance like this:
+
+```php
+$stdin = new ReadableResourceStream(STDIN, $loop);
+$stdout = new WritableResourceStream(STDOUT, $loop);
+
+$stdio = new CompositeStream($stdin, $stdout);
+
+$stdio->on('data', function ($chunk) use ($stdio) {
+    $stdio->write('You said: ' . $chunk);
+});
+```
+
+This is a well-behaving stream which forwards all stream events from the
+underlying streams and forwards all streams calls to the underlying streams.
+
+If you `write()` to the duplex stream, it will simply `write()` to the
+writable side and return its status.
+
+If you `end()` the duplex stream, it will `end()` the writable side and will
+`pause()` the readable side.
+
+If you `close()` the duplex stream, both input streams will be closed.
+If either of the two input streams emits a `close` event, the duplex stream
+will also close.
+If either of the two input streams is already closed while constructing the
+duplex stream, it will `close()` the other side and return a closed stream.
+
+## Usage
+
+The following example can be used to pipe the contents of a source file into
+a destination file without having to ever read the whole file into memory:
+
+```php
+$loop = new React\EventLoop\StreamSelectLoop;
+
+$source = new React\Stream\ReadableResourceStream(fopen('source.txt', 'r'), $loop);
+$dest = new React\Stream\WritableResourceStream(fopen('destination.txt', 'w'), $loop);
+
+$source->pipe($dest);
+
+$loop->run();
+```
+
+> Note that this example uses `fopen()` for illustration purposes only.
+  This should not be used in a truly async program because the filesystem is
+  inherently blocking and each call could potentially take several seconds.
+  See also [creating streams](#creating-streams) for more sophisticated
+  examples.
+

+/**
+ * The `DuplexStreamInterface` is responsible for providing an interface for
+ * duplex streams (both readable and writable).
+ *
+ * It builds on top of the existing interfaces for readable and writable streams
+ * and follows the exact same method and event semantics.
+ * If you're new to this concept, you should look into the
+ * `ReadableStreamInterface` and `WritableStreamInterface` first.
+ *
+ * Besides defining a few methods, this interface also implements the
+ * `EventEmitterInterface` which allows you to react to the same events defined
+ * on the `ReadbleStreamInterface` and `WritableStreamInterface`.
+ *
+ * The event callback functions MUST be a valid `callable` that obeys strict
+ * parameter definitions and MUST accept event parameters exactly as documented.
+ * The event callback functions MUST NOT throw an `Exception`.
+ * The return value of the event callback functions will be ignored and has no
+ * effect, so for performance reasons you're recommended to not return any
+ * excessive data structures.
+ *
+ * Every implementation of this interface MUST follow these event semantics in
+ * order to be considered a well-behaving stream.
+ *
+ * > Note that higher-level implementations of this interface may choose to
+ *   define additional events with dedicated semantics not defined as part of
+ *   this low-level stream specification. Conformance with these event semantics
+ *   is out of scope for this interface, so you may also have to refer to the
+ *   documentation of such a higher-level implementation.

+/**
+ * The `ReadableStreamInterface` is responsible for providing an interface for
+ * read-only streams and the readable side of duplex streams.
+ *
+ * Besides defining a few methods, this interface also implements the
+ * `EventEmitterInterface` which allows you to react to certain events:
+ *
+ * data event:
+ *     The `data` event will be emitted whenever some data was read/received
+ *     from this source stream.
+ *     The event receives a single mixed argument for incoming data.
+ *
+ *     ```php
+ *     $stream->on('data', function ($data) {
+ *         echo $data;
+ *     });
+ *     ```
+ *
+ *     This event MAY be emitted any number of times, which may be zero times if
+ *     this stream does not send any data at all.
+ *     It SHOULD not be emitted after an `end` or `close` event.
+ *
+ *     The given `$data` argument may be of mixed type, but it's usually
+ *     recommended it SHOULD be a `string` value or MAY use a type that allows
+ *     representation as a `string` for maximum compatibility.
+ *
+ *     Many common streams (such as a TCP/IP connection or a file-based stream)
+ *     will emit the raw (binary) payload data that is received over the wire as
+ *     chunks of `string` values.
+ *
+ *     Due to the stream-based nature of this, the sender may send any number
+ *     of chunks with varying sizes. There are no guarantees that these chunks
+ *     will be received with the exact same framing the sender intended to send.
+ *     In other words, many lower-level protocols (such as TCP/IP) transfer the
+ *     data in chunks that may be anywhere between single-byte values to several
+ *     dozens of kilobytes. You may want to apply a higher-level protocol to
+ *     these low-level data chunks in order to achieve proper message framing.
+ *
+ * end event:
+ *     The `end` event will be emitted once the source stream has successfully
+ *     reached the end of the stream (EOF).
+ *
+ *     ```php
+ *     $stream->on('end', function () {
+ *         echo 'END';
+ *     });
+ *     ```
+ *
+ *     This event SHOULD be emitted once or never at all, depending on whether
+ *     a successful end was detected.
+ *     It SHOULD NOT be emitted after a previous `end` or `close` event.
+ *     It MUST NOT be emitted if the stream closes due to a non-successful
+ *     end, such as after a previous `error` event.
+ *
+ *     After the stream is ended, it MUST switch to non-readable mode,
+ *     see also `isReadable()`.
+ *
+ *     This event will only be emitted if the *end* was reached successfully,
+ *     not if the stream was interrupted by an unrecoverable error or explicitly
+ *     closed. Not all streams know this concept of a "successful end".
+ *     Many use-cases involve detecting when the stream closes (terminates)
+ *     instead, in this case you should use the `close` event.
+ *     After the stream emits an `end` event, it SHOULD usually be followed by a
+ *     `close` event.
+ *
+ *     Many common streams (such as a TCP/IP connection or a file-based stream)
+ *     will emit this event if either the remote side closes the connection or
+ *     a file handle was successfully read until reaching its end (EOF).
+ *
+ *     Note that this event should not be confused with the `end()` method.
+ *     This event defines a successful end *reading* from a source stream, while
+ *     the `end()` method defines *writing* a successful end to a destination
+ *     stream.
+ *
+ * error event:
+ *     The `error` event will be emitted once a fatal error occurs, usually while
+ *     trying to read from this stream.
+ *     The event receives a single `Exception` argument for the error instance.
+ *
+ *     ```php
+ *     $stream->on('error', function (Exception $e) {
+ *         echo 'Error: ' . $e->getMessage() . PHP_EOL;
+ *     });
+ *     ```
+ *
+ *     This event SHOULD be emitted once the stream detects a fatal error, such
+ *     as a fatal transmission error or after an unexpected `data` or premature
+ *     `end` event.
+ *     It SHOULD NOT be emitted after a previous `error`, `end` or `close` event.
+ *     It MUST NOT be emitted if this is not a fatal error condition, such as
+ *     a temporary network issue that did not cause any data to be lost.
+ *
+ *     After the stream errors, it MUST close the stream and SHOULD thus be
+ *     followed by a `close` event and then switch to non-readable mode, see
+ *     also `close()` and `isReadable()`.
+ *
+ *     Many common streams (such as a TCP/IP connection or a file-based stream)
+ *     only deal with data transmission and do not make assumption about data
+ *     boundaries (such as unexpected `data` or premature `end` events).
+ *     In other words, many lower-level protocols (such as TCP/IP) may choose
+ *     to only emit this for a fatal transmission error once and will then
+ *     close (terminate) the stream in response.
+ *
+ *     If this stream is a `DuplexStreamInterface`, you should also notice
+ *     how the writable side of the stream also implements an `error` event.
+ *     In other words, an error may occur while either reading or writing the
+ *     stream which should result in the same error processing.
+ *
+ * close event:
+ *     The `close` event will be emitted once the stream closes (terminates).
+ *
+ *     ```php
+ *     $stream->on('close', function () {
+ *         echo 'CLOSED';
+ *     });
+ *     ```
+ *
+ *     This event SHOULD be emitted once or never at all, depending on whether
+ *     the stream ever terminates.
+ *     It SHOULD NOT be emitted after a previous `close` event.
+ *
+ *     After the stream is closed, it MUST switch to non-readable mode,
+ *     see also `isReadable()`.
+ *
+ *     Unlike the `end` event, this event SHOULD be emitted whenever the stream
+ *     closes, irrespective of whether this happens implicitly due to an
+ *     unrecoverable error or explicitly when either side closes the stream.
+ *     If you only want to detect a *successful* end, you should use the `end`
+ *     event instead.
+ *
+ *     Many common streams (such as a TCP/IP connection or a file-based stream)
+ *     will likely choose to emit this event after reading a *successful* `end`
+ *     event or after a fatal transmission `error` event.
+ *
+ *     If this stream is a `DuplexStreamInterface`, you should also notice
+ *     how the writable side of the stream also implements a `close` event.
+ *     In other words, after receiving this event, the stream MUST switch into
+ *     non-writable AND non-readable mode, see also `isWritable()`.
+ *     Note that this event should not be confused with the `end` event.
+ *
+ * The event callback functions MUST be a valid `callable` that obeys strict
+ * parameter definitions and MUST accept event parameters exactly as documented.
+ * The event callback functions MUST NOT throw an `Exception`.
+ * The return value of the event callback functions will be ignored and has no
+ * effect, so for performance reasons you're recommended to not return any
+ * excessive data structures.
+ *
+ * Every implementation of this interface MUST follow these event semantics in
+ * order to be considered a well-behaving stream.
+ *
+ * > Note that higher-level implementations of this interface may choose to
+ *   define additional events with dedicated semantics not defined as part of
+ *   this low-level stream specification. Conformance with these event semantics
+ *   is out of scope for this interface, so you may also have to refer to the
+ *   documentation of such a higher-level implementation.

+/**
+ * The `WritableStreamInterface` is responsible for providing an interface for
+ * write-only streams and the writable side of duplex streams.
+ *
+ * Besides defining a few methods, this interface also implements the
+ * `EventEmitterInterface` which allows you to react to certain events:
+ *
+ * drain event:
+ *     The `drain` event will be emitted whenever the write buffer became full
+ *     previously and is now ready to accept more data.
+ *
+ *     ```php
+ *     $stream->on('drain', function () use ($stream) {
+ *         echo 'Stream is now ready to accept more data';
+ *     });
+ *     ```
+ *
+ *     This event SHOULD be emitted once every time the buffer became full
+ *     previously and is now ready to accept more data.
+ *     In other words, this event MAY be emitted any number of times, which may
+ *     be zero times if the buffer never became full in the first place.
+ *     This event SHOULD NOT be emitted if the buffer has not become full
+ *     previously.
+ *
+ *     This event is mostly used internally, see also `write()` for more details.
+ *
+ * pipe event:
+ *     The `pipe` event will be emitted whenever a readable stream is `pipe()`d
+ *     into this stream.
+ *     The event receives a single `ReadableStreamInterface` argument for the
+ *     source stream.
+ *
+ *     ```php
+ *     $stream->on('pipe', function (ReadableStreamInterface $source) use ($stream) {
+ *         echo 'Now receiving piped data';
+ *
+ *         // explicitly close target if source emits an error
+ *         $source->on('error', function () use ($stream) {
+ *             $stream->close();
+ *         });
+ *     });
+ *
+ *     $source->pipe($stream);
+ *     ```
+ *
+ *     This event MUST be emitted once for each readable stream that is
+ *     successfully piped into this destination stream.
+ *     In other words, this event MAY be emitted any number of times, which may
+ *     be zero times if no stream is ever piped into this stream.
+ *     This event MUST NOT be emitted if either the source is not readable
+ *     (closed already) or this destination is not writable (closed already).
+ *
+ *     This event is mostly used internally, see also `pipe()` for more details.
+ *
+ * error event:
+ *     The `error` event will be emitted once a fatal error occurs, usually while
+ *     trying to write to this stream.
+ *     The event receives a single `Exception` argument for the error instance.
+ *
+ *     ```php
+ *     $stream->on('error', function (Exception $e) {
+ *         echo 'Error: ' . $e->getMessage() . PHP_EOL;
+ *     });
+ *     ```
+ *
+ *     This event SHOULD be emitted once the stream detects a fatal error, such
+ *     as a fatal transmission error.
+ *     It SHOULD NOT be emitted after a previous `error` or `close` event.
+ *     It MUST NOT be emitted if this is not a fatal error condition, such as
+ *     a temporary network issue that did not cause any data to be lost.
+ *
+ *     After the stream errors, it MUST close the stream and SHOULD thus be
+ *     followed by a `close` event and then switch to non-writable mode, see
+ *     also `close()` and `isWritable()`.
+ *
+ *     Many common streams (such as a TCP/IP connection or a file-based stream)
+ *     only deal with data transmission and may choose
+ *     to only emit this for a fatal transmission error once and will then
+ *     close (terminate) the stream in response.
+ *
+ *     If this stream is a `DuplexStreamInterface`, you should also notice
+ *     how the readable side of the stream also implements an `error` event.
+ *     In other words, an error may occur while either reading or writing the
+ *     stream which should result in the same error processing.
+ *
+ * close event:
+ *     The `close` event will be emitted once the stream closes (terminates).
+ *
+ *     ```php
+ *     $stream->on('close', function () {
+ *         echo 'CLOSED';
+ *     });
+ *     ```
+ *
+ *     This event SHOULD be emitted once or never at all, depending on whether
+ *     the stream ever terminates.
+ *     It SHOULD NOT be emitted after a previous `close` event.
+ *
+ *     After the stream is closed, it MUST switch to non-writable mode,
+ *     see also `isWritable()`.
+ *
+ *     This event SHOULD be emitted whenever the stream closes, irrespective of
+ *     whether this happens implicitly due to an unrecoverable error or
+ *     explicitly when either side closes the stream.
+ *
+ *     Many common streams (such as a TCP/IP connection or a file-based stream)
+ *     will likely choose to emit this event after flushing the buffer from
+ *     the `end()` method, after receiving a *successful* `end` event or after
+ *     a fatal transmission `error` event.
+ *
+ *     If this stream is a `DuplexStreamInterface`, you should also notice
+ *     how the readable side of the stream also implements a `close` event.
+ *     In other words, after receiving this event, the stream MUST switch into
+ *     non-writable AND non-readable mode, see also `isReadable()`.
+ *     Note that this event should not be confused with the `end` event.
+ *
+ * The event callback functions MUST be a valid `callable` that obeys strict
+ * parameter definitions and MUST accept event parameters exactly as documented.
+ * The event callback functions MUST NOT throw an `Exception`.
+ * The return value of the event callback functions will be ignored and has no
+ * effect, so for performance reasons you're recommended to not return any
+ * excessive data structures.
+ *
+ * Every implementation of this interface MUST follow these event semantics in
+ * order to be considered a well-behaving stream.
+ *
+ * > Note that higher-level implementations of this interface may choose to
+ *   define additional events with dedicated semantics not defined as part of
+ *   this low-level stream specification. Conformance with these event semantics
+ *   is out of scope for this interface, so you may also have to refer to the
+ *   documentation of such a higher-level implementation.

+     * Unlike the `end()` method, this method does not take care of any existing
+     * buffers and simply discards any buffer contents.

+# PSR-7 Message Implementation
+
+This repository contains a partial [PSR-7](http://www.php-fig.org/psr/psr-7/)
+message implementation, several stream decorators, and some helpful
+functionality like query string parsing.  Currently missing
+ServerRequestInterface and UploadedFileInterface; a pull request for these features is welcome.
+
+
+# Stream implementation
+
+This package comes with a number of stream implementations and stream
+decorators.
+
+
+## AppendStream
+
+`RingCentral\Psr7\AppendStream`
+
+Reads from multiple streams, one after the other.
+
+```php
+use RingCentral\Psr7;
+
+$a = Psr7\stream_for('abc, ');
+$b = Psr7\stream_for('123.');
+$composed = new Psr7\AppendStream([$a, $b]);
+
+$composed->addStream(Psr7\stream_for(' Above all listen to me').
+
+echo $composed(); // abc, 123. Above all listen to me.
+```
+
+
+## BufferStream
+
+`RingCentral\Psr7\BufferStream`
+
+Provides a buffer stream that can be written to to fill a buffer, and read
+from to remove bytes from the buffer.
+
+This stream returns a "hwm" metadata value that tells upstream consumers
+what the configured high water mark of the stream is, or the maximum
+preferred size of the buffer.
+
+```php
+use RingCentral\Psr7;
+
+// When more than 1024 bytes are in the buffer, it will begin returning
+// false to writes. This is an indication that writers should slow down.
+$buffer = new Psr7\BufferStream(1024);
+```
+
+
+## CachingStream
+
+The CachingStream is used to allow seeking over previously read bytes on
+non-seekable streams. This can be useful when transferring a non-seekable
+entity body fails due to needing to rewind the stream (for example, resulting
+from a redirect). Data that is read from the remote stream will be buffered in
+a PHP temp stream so that previously read bytes are cached first in memory,
+then on disk.
+
+```php
+use RingCentral\Psr7;
+
+$original = Psr7\stream_for(fopen('http://www.google.com', 'r'));
+$stream = new Psr7\CachingStream($original);
+
+$stream->read(1024);
+echo $stream->tell();
+// 1024
+
+$stream->seek(0);
+echo $stream->tell();
+// 0
+```
+
+
+## DroppingStream
+
+`RingCentral\Psr7\DroppingStream`
+
+Stream decorator that begins dropping data once the size of the underlying
+stream becomes too full.
+
+```php
+use RingCentral\Psr7;
+
+// Create an empty stream
+$stream = Psr7\stream_for();
+
+// Start dropping data when the stream has more than 10 bytes
+$dropping = new Psr7\DroppingStream($stream, 10);
+
+$stream->write('01234567890123456789');
+echo $stream; // 0123456789
+```
+
+
+## FnStream
+
+`RingCentral\Psr7\FnStream`
+
+Compose stream implementations based on a hash of functions.
+
+Allows for easy testing and extension of a provided stream without needing to
+to create a concrete class for a simple extension point.
+
+```php
+
+use RingCentral\Psr7;
+
+$stream = Psr7\stream_for('hi');
+$fnStream = Psr7\FnStream::decorate($stream, [
+    'rewind' => function () use ($stream) {
+        echo 'About to rewind - ';
+        $stream->rewind();
+        echo 'rewound!';
+    }
+]);
+
+$fnStream->rewind();
+// Outputs: About to rewind - rewound!
+```
+
+
+## InflateStream
+
+`RingCentral\Psr7\InflateStream`
+
+Uses PHP's zlib.inflate filter to inflate deflate or gzipped content.
+
+This stream decorator skips the first 10 bytes of the given stream to remove
+the gzip header, converts the provided stream to a PHP stream resource,
+then appends the zlib.inflate filter. The stream is then converted back
+to a Guzzle stream resource to be used as a Guzzle stream.
+
+
+## LazyOpenStream
+
+`RingCentral\Psr7\LazyOpenStream`
+
+Lazily reads or writes to a file that is opened only after an IO operation
+take place on the stream.
+
+```php
+use RingCentral\Psr7;
+
+$stream = new Psr7\LazyOpenStream('/path/to/file', 'r');
+// The file has not yet been opened...
+
+echo $stream->read(10);
+// The file is opened and read from only when needed.
+```
+
+
+## LimitStream
+
+`RingCentral\Psr7\LimitStream`
+
+LimitStream can be used to read a subset or slice of an existing stream object.
+This can be useful for breaking a large file into smaller pieces to be sent in
+chunks (e.g. Amazon S3's multipart upload API).
+
+```php
+use RingCentral\Psr7;
+
+$original = Psr7\stream_for(fopen('/tmp/test.txt', 'r+'));
+echo $original->getSize();
+// >>> 1048576
+
+// Limit the size of the body to 1024 bytes and start reading from byte 2048
+$stream = new Psr7\LimitStream($original, 1024, 2048);
+echo $stream->getSize();
+// >>> 1024
+echo $stream->tell();
+// >>> 0
+```
+
+
+## MultipartStream
+
+`RingCentral\Psr7\MultipartStream`
+
+Stream that when read returns bytes for a streaming multipart or
+multipart/form-data stream.
+
+
+## NoSeekStream
+
+`RingCentral\Psr7\NoSeekStream`
+
+NoSeekStream wraps a stream and does not allow seeking.
+
+```php
+use RingCentral\Psr7;
+
+$original = Psr7\stream_for('foo');
+$noSeek = new Psr7\NoSeekStream($original);
+
+echo $noSeek->read(3);
+// foo
+var_export($noSeek->isSeekable());
+// false
+$noSeek->seek(0);
+var_export($noSeek->read(3));
+// NULL
+```
+
+
+## PumpStream
+
+`RingCentral\Psr7\PumpStream`
+
+Provides a read only stream that pumps data from a PHP callable.
+
+When invoking the provided callable, the PumpStream will pass the amount of
+data requested to read to the callable. The callable can choose to ignore
+this value and return fewer or more bytes than requested. Any extra data
+returned by the provided callable is buffered internally until drained using
+the read() function of the PumpStream. The provided callable MUST return
+false when there is no more data to read.
+
+
+## Implementing stream decorators
+
+Creating a stream decorator is very easy thanks to the
+`RingCentral\Psr7\StreamDecoratorTrait`. This trait provides methods that
+implement `Psr\Http\Message\StreamInterface` by proxying to an underlying
+stream. Just `use` the `StreamDecoratorTrait` and implement your custom
+methods.
+
+For example, let's say we wanted to call a specific function each time the last
+byte is read from a stream. This could be implemented by overriding the
+`read()` method.
+
+```php
+use Psr\Http\Message\StreamInterface;
+use RingCentral\Psr7\StreamDecoratorTrait;
+
+class EofCallbackStream implements StreamInterface
+{
+    use StreamDecoratorTrait;
+
+    private $callback;
+
+    public function __construct(StreamInterface $stream, callable $cb)
+    {
+        $this->stream = $stream;
+        $this->callback = $cb;
+    }
+
+    public function read($length)
+    {
+        $result = $this->stream->read($length);
+
+        // Invoke the callback when EOF is hit.
+        if ($this->eof()) {
+            call_user_func($this->callback);
+        }
+
+        return $result;
+    }
+}
+```
+
+This decorator could be added to any existing stream and used like so:
+
+```php
+use RingCentral\Psr7;
+
+$original = Psr7\stream_for('foo');
+
+$eofStream = new EofCallbackStream($original, function () {
+    echo 'EOF!';
+});
+
+$eofStream->read(2);
+$eofStream->read(1);
+// echoes "EOF!"
+$eofStream->seek(0);
+$eofStream->read(3);
+// echoes "EOF!"
+```
+
+
+## PHP StreamWrapper
+
+You can use the `RingCentral\Psr7\StreamWrapper` class if you need to use a
+PSR-7 stream as a PHP stream resource.
+
+Use the `RingCentral\Psr7\StreamWrapper::getResource()` method to create a PHP
+stream from a PSR-7 stream.
+
+```php
+use RingCentral\Psr7\StreamWrapper;
+
+$stream = RingCentral\Psr7\stream_for('hello!');
+$resource = StreamWrapper::getResource($stream);
+echo fread($resource, 6); // outputs hello!
+```
+
+
+# Function API
+
+There are various functions available under the `RingCentral\Psr7` namespace.
+
+
+## `function str`
+
+`function str(MessageInterface $message)`
+
+Returns the string representation of an HTTP message.
+
+```php
+$request = new RingCentral\Psr7\Request('GET', 'http://example.com');
+echo RingCentral\Psr7\str($request);
+```
+
+
+## `function uri_for`
+
+`function uri_for($uri)`
+
+This function accepts a string or `Psr\Http\Message\UriInterface` and returns a
+UriInterface for the given value. If the value is already a `UriInterface`, it
+is returned as-is.
+
+```php
+$uri = RingCentral\Psr7\uri_for('http://example.com');
+assert($uri === RingCentral\Psr7\uri_for($uri));
+```
+
+
+## `function stream_for`
+
+`function stream_for($resource = '', array $options = [])`
+
+Create a new stream based on the input type.
+
+Options is an associative array that can contain the following keys:
+
+* - metadata: Array of custom metadata.
+* - size: Size of the stream.
+
+This method accepts the following `$resource` types:
+
+- `Psr\Http\Message\StreamInterface`: Returns the value as-is.
+- `string`: Creates a stream object that uses the given string as the contents.
+- `resource`: Creates a stream object that wraps the given PHP stream resource.
+- `Iterator`: If the provided value implements `Iterator`, then a read-only
+  stream object will be created that wraps the given iterable. Each time the
+  stream is read from, data from the iterator will fill a buffer and will be
+  continuously called until the buffer is equal to the requested read size.
+  Subsequent read calls will first read from the buffer and then call `next`
+  on the underlying iterator until it is exhausted.
+- `object` with `__toString()`: If the object has the `__toString()` method,
+  the object will be cast to a string and then a stream will be returned that
+  uses the string value.
+- `NULL`: When `null` is passed, an empty stream object is returned.
+- `callable` When a callable is passed, a read-only stream object will be
+  created that invokes the given callable. The callable is invoked with the
+  number of suggested bytes to read. The callable can return any number of
+  bytes, but MUST return `false` when there is no more data to return. The
+  stream object that wraps the callable will invoke the callable until the
+  number of requested bytes are available. Any additional bytes will be
+  buffered and used in subsequent reads.
+
+```php
+$stream = RingCentral\Psr7\stream_for('foo');
+$stream = RingCentral\Psr7\stream_for(fopen('/path/to/file', 'r'));
+
+$generator function ($bytes) {
+    for ($i = 0; $i < $bytes; $i++) {
+        yield ' ';
+    }
+}
+
+$stream = RingCentral\Psr7\stream_for($generator(100));
+```
+
+
+## `function parse_header`
+
+`function parse_header($header)`
+
+Parse an array of header values containing ";" separated data into an array of
+associative arrays representing the header key value pair data of the header.
+When a parameter does not contain a value, but just contains a key, this
+function will inject a key with a '' string value.
+
+
+## `function normalize_header`
+
+`function normalize_header($header)`
+
+Converts an array of header values that may contain comma separated headers
+into an array of headers with no comma separated values.
+
+
+## `function modify_request`
+
+`function modify_request(RequestInterface $request, array $changes)`
+
+Clone and modify a request with the given changes. This method is useful for
+reducing the number of clones needed to mutate a message.
+
+The changes can be one of:
+
+- method: (string) Changes the HTTP method.
+- set_headers: (array) Sets the given headers.
+- remove_headers: (array) Remove the given headers.

+- uri: (UriInterface) Set the URI.
+- query: (string) Set the query string value of the URI.
+- version: (string) Set the protocol version.
+
+
+## `function rewind_body`
+
+`function rewind_body(MessageInterface $message)`
+
+Attempts to rewind a message body and throws an exception on failure. The body
+of the message will only be rewound if a call to `tell()` returns a value other
+than `0`.
+
+
+## `function try_fopen`
+
+`function try_fopen($filename, $mode)`
+
+Safely opens a PHP stream resource using a filename.
+
+When fopen fails, PHP normally raises a warning. This function adds an error
+handler that checks for errors and throws an exception instead.
+
+
+## `function copy_to_string`
+
+`function copy_to_string(StreamInterface $stream, $maxLen = -1)`
+
+Copy the contents of a stream into a string until the given number of bytes
+have been read.
+
+
+## `function copy_to_stream`
+
+`function copy_to_stream(StreamInterface $source, StreamInterface $dest, $maxLen = -1)`
+
+Copy the contents of a stream into another stream until the given number of
+bytes have been read.
+
+
+## `function hash`
+
+`function hash(StreamInterface $stream, $algo, $rawOutput = false)`
+
+Calculate a hash of a Stream. This method reads the entire stream to calculate
+a rolling hash (based on PHP's hash_init functions).
+
+
+## `function readline`
+
+`function readline(StreamInterface $stream, $maxLength = null)`
+
+Read a line from the stream up to the maximum allowed buffer length.
+
+
+## `function parse_request`
+
+`function parse_request($message)`
+
+Parses a request message string into a request object.
+
+
+## `function parse_server_request`
+
+`function parse_server_request($message, array $serverParams = array())`
+
+Parses a request message string into a server-side request object.
+
+
+## `function parse_response`
+
+`function parse_response($message)`
+
+Parses a response message string into a response object.
+
+
+## `function parse_query`
+
+`function parse_query($str, $urlEncoding = true)`
+
+Parse a query string into an associative array.
+
+If multiple values are found for the same key, the value of that key value pair
+will become an array. This function does not parse nested PHP style arrays into
+an associative array (e.g., `foo[a]=1&foo[b]=2` will be parsed into
+`['foo[a]' => '1', 'foo[b]' => '2']`).
+
+
+## `function build_query`
+
+`function build_query(array $params, $encoding = PHP_QUERY_RFC3986)`
+
+Build a query string from an array of key value pairs.
+
+This function can use the return value of parseQuery() to build a query string.
+This function does not modify the provided keys when an array is encountered
+(like http_build_query would).
+
+
+## `function mimetype_from_filename`
+
+`function mimetype_from_filename($filename)`
+
+Determines the mimetype of a file by looking at its extension.
+
+
+## `function mimetype_from_extension`
+
+`function mimetype_from_extension($extension)`
+
+Maps a file extensions to a mimetype.
+
+
+# Static URI methods
+
+The `RingCentral\Psr7\Uri` class has several static methods to manipulate URIs.
+
+
+## `RingCentral\Psr7\Uri::removeDotSegments`
+
+`public static function removeDotSegments($path) -> UriInterface`
+
+Removes dot segments from a path and returns the new path.
+
+See http://tools.ietf.org/html/rfc3986#section-5.2.4
+
+
+## `RingCentral\Psr7\Uri::resolve`
+
+`public static function resolve(UriInterface $base, $rel) -> UriInterface`
+
+Resolve a base URI with a relative URI and return a new URI.
+
+See http://tools.ietf.org/html/rfc3986#section-5
+
+
+## `RingCentral\Psr7\Uri::withQueryValue`
+
+`public static function withQueryValue(UriInterface $uri, $key, $value) -> UriInterface`
+
+Create a new URI with a specific query string value.
+
+Any existing query string values that exactly match the provided key are
+removed and replaced with the given key value pair.
+
+Note: this function will convert "=" to "%3D" and "&" to "%26".
+
+
+## `RingCentral\Psr7\Uri::withoutQueryValue`
+
+`public static function withoutQueryValue(UriInterface $uri, $key, $value) -> UriInterface`
+
+Create a new URI with a specific query string value removed.
+
+Any existing query string values that exactly match the provided key are
+removed.
+
+Note: this function will convert "=" to "%3D" and "&" to "%26".
+
+
+## `RingCentral\Psr7\Uri::fromParts`
+
+`public static function fromParts(array $parts) -> UriInterface`
+
+Create a `RingCentral\Psr7\Uri` object from a hash of `parse_url` parts.
+

+# fbns-react
+
+A PHP client for the FBNS built on top of ReactPHP.
+
+## Requirements
+
+You need to install the [GMP extension](http://php.net/manual/en/book.gmp.php) to be able to run this code on x86 PHP builds.
+
+## Installation
+
+```sh
+composer require valga/fbns-react
+```
+
+## Basic Usage
+
+```php
+// Set up a FBNS client.
+$loop = \React\EventLoop\Factory::create();
+$client = new \Fbns\Client\Lite($loop);
+
+// Read saved credentials from a storage.
+$auth = new \Fbns\Client\Auth\DeviceAuth();
+try {
+    $auth->read($storage->get('fbns_auth'));
+} catch (\Exception $e) {
+}
+
+// Connect to a broker.
+$connection = new \Fbns\Client\Connection($deviceAuth, USER_AGENT);
+$client->connect(HOSTNAME, PORT, $connection);
+
+// Bind events.
+$client
+    ->on('connect', function (\Fbns\Client\Lite\ConnectResponsePacket $responsePacket) use ($client, $auth, $storage) {
+        // Update credentials and save them to a storage for future use.
+        try {
+            $auth->read($responsePacket->getAuth());
+            $storage->set('fbns_auth', $responsePacket->getAuth());
+        } catch (\Exception $e) {
+        }
+        
+        // Register an application.
+        $client->register(PACKAGE_NAME, APPLICATION_ID);
+    })
+    ->on('register', function (\Fbns\Client\Message\Register $message) use ($app) {
+        // Register received token with an application.
+        $app->registerPushToken($message->getToken());
+    })
+    ->on('push', function (\Fbns\Client\Message\Push $message) use ($app) {
+        // Handle received notification payload.
+        $app->handlePushNotification($message->getPayload());
+    });
+
+// Run main loop.
+$loop->run();
+```
+
+## Advanced Usage
+
+```php
+// Set up a proxy.
+$connector = new \React\Socket\Connector($loop);
+$proxy = new \Clue\React\HttpProxy('username:password@127.0.0.1:3128', $connector);
+
+// Disable SSL verification.
+$ssl = new \React\Socket\SecureConnector($proxy, $loop, ['verify_peer' => false, 'verify_peer_name' => false]);
+
+// Enable logging to stdout.
+$logger = new \Monolog\Logger('fbns');
+$logger->pushHandler(new \Monolog\Handler\StreamHandler('php://stdout', \Monolog\Logger::INFO));
+
+// Set up a client.
+$client = new \Fbns\Client\Lite($loop, $ssl, $logger);
+
+// Persistence.
+$client->on('disconnect', function () {
+    // Network connection has been closed. You can reestablish it if you want to.
+});
+$client->connect(HOSTNAME, PORT, $connection)
+    ->otherwise(function () {
+        // Connection attempt was unsuccessful, retry with an exponential backoff.
+    });
+```

+Winbox-Args
+===========
+
+[![Build Status](https://travis-ci.org/johnstevenson/winbox-args.svg?branch=master)](https://travis-ci.org/johnstevenson/winbox-args)
+[![Build status](https://ci.appveyor.com/api/projects/status/p4k75qqcyioj0mfl?svg=true)](https://ci.appveyor.com/project/johnstevenson/winbox-args)
+
+A PHP function to escape command-line arguments, which on Windows replaces `escapeshellarg` with a more robust method. Install from [Packagist][packagist] and use it like this:
+
+```php
+$escaped = Winbox\Args::escape($argument);
+```
+
+Alternatively, you can just [copy the code][function] into your own project (but please keep the license attribution and documentation link).
+
+### What it does
+The following transformations are made:
+
+* Double-quotes are escaped with a backslash, with any preceeding backslashes doubled up.
+* The argument is only enclosed in double-quotes if it contains whitespace or is empty.
+* Trailing backslashes are doubled up if the argument is enclosed in double-quotes.
+
+See [How Windows parses the command-line](https://github.com/johnstevenson/winbox-args/wiki/How-Windows-parses-the-command-line) if you would like to know why.
+
+By default, _cmd.exe_ meta characters are also escaped:
+
+* by caret-escaping the transformed argument (if it contains internal double-quotes or `%...%` syntax).
+* or by enclosing the argument in double-quotes.
+
+There are a couple limitations:
+
+1. If _cmd_ is started with _DelayedExpansion_ enabled, `!...!` syntax could expand environment variables.
+2. If the program name requires caret-escaping and contains whitespace, _cmd_ will not recognize it.
+
+See [How cmd.exe parses a command](https://github.com/johnstevenson/winbox-args/wiki/How-cmd.exe-parses-a-command) and [Implementing a solution](https://github.com/johnstevenson/winbox-args/wiki/Implementing-a-solution) for more information.
+
+### Is that it?
+Yup. An entire repo for a tiny function. However, it needs quite a lot of explanation because:
+
+* the command-line parsing rules in Windows are not immediately obvious.
+* PHP generally uses _cmd.exe_ to execute programs and this applies a different set of rules.
+* there is no simple solution.
+
+Full details explaining the different parsing rules, potential pitfalls and limitations can be found in the [Wiki][wiki].

+
+This package provides an asynchronous MQTT client built on the [React socket](https://github.com/reactphp/socket) library. All client methods return a promise which is fulfilled if the operation succeeded or rejected if the operation failed. Incoming messages of subscribed topics are delivered via the "message" event.
+
+## Install
+
+Via composer:
+
+``` bash
+$ composer require binsoul/net-mqtt-client-react
+```
+
+## Example
+
+Connect to a public broker and run forever.

+# clue/http-proxy-react [![Build Status](https://travis-ci.org/clue/php-http-proxy-react.svg?branch=master)](https://travis-ci.org/clue/php-http-proxy-react)
+
+Async HTTP proxy connector, use any TCP/IP-based protocol through an HTTP
+CONNECT proxy server, built on top of [ReactPHP](https://reactphp.org).
+
+HTTP CONNECT proxy servers (also commonly known as "HTTPS proxy" or "SSL proxy")
+are commonly used to tunnel HTTPS traffic through an intermediary ("proxy"), to
+conceal the origin address (anonymity) or to circumvent address blocking
+(geoblocking). While many (public) HTTP CONNECT proxy servers often limit this
+to HTTPS port `443` only, this can technically be used to tunnel any
+TCP/IP-based protocol (HTTP, SMTP, IMAP etc.).
+This library provides a simple API to create these tunneled connection for you.
+Because it implements ReactPHP's standard
+[`ConnectorInterface`](https://github.com/reactphp/socket#connectorinterface),
+it can simply be used in place of a normal connector.
+This makes it fairly simple to add HTTP CONNECT proxy support to pretty much any
+existing higher-level protocol implementation.
+
+* **Async execution of connections** -
+  Send any number of HTTP CONNECT requests in parallel and process their
+  responses as soon as results come in.
+  The Promise-based design provides a *sane* interface to working with out of
+  bound responses and possible connection errors.
+* **Standard interfaces** -
+  Allows easy integration with existing higher-level components by implementing
+  ReactPHP's standard
+  [`ConnectorInterface`](https://github.com/reactphp/socket#connectorinterface).
+* **Lightweight, SOLID design** -
+  Provides a thin abstraction that is [*just good enough*](http://en.wikipedia.org/wiki/Principle_of_good_enough)
+  and does not get in your way.
+  Builds on top of well-tested components and well-established concepts instead of reinventing the wheel.
+* **Good test coverage** -
+  Comes with an automated tests suite and is regularly tested against actual proxy servers in the wild

+### Quickstart example
+
+The following example code demonstrates how this library can be used to send a
+secure HTTPS request to google.com through a local HTTP proxy server:
+
+```php
+$loop = React\EventLoop\Factory::create();
+
+$proxy = new ProxyConnector('127.0.0.1:8080', new Connector($loop));
+$connector = new Connector($loop, array(
+    'tcp' => $proxy,
+    'timeout' => 3.0,
+    'dns' => false
+));
+
+$connector->connect('tls://google.com:443')->then(function (ConnectionInterface $stream) {
+    $stream->write("GET / HTTP/1.1\r\nHost: google.com\r\nConnection: close\r\n\r\n");
+    $stream->on('data', function ($chunk) {
+        echo $chunk;
+    });
+}, 'printf');
+
+$loop->run();
+```
+
+See also the [examples](examples).
+
+## Usage
+
+### ProxyConnector
+
+The `ProxyConnector` is responsible for creating plain TCP/IP connections to
+any destination by using an intermediary HTTP CONNECT proxy.
+
+```
+[you] -> [proxy] -> [destination]
+```
+
+Its constructor simply accepts an HTTP proxy URL and a connector used to connect
+to the proxy server address:
+
+```php
+$connector = new Connector($loop);
+$proxy = new ProxyConnector('http://127.0.0.1:8080', $connector);
+```
+
+The proxy URL may or may not contain a scheme and port definition. The default
+port will be `80` for HTTP (or `443` for HTTPS), but many common HTTP proxy
+servers use custom ports (often the alternative HTTP port `8080`).
+In its most simple form, the given connector will be a
+[`\React\Socket\Connector`](https://github.com/reactphp/socket#connector) if you
+want to connect to a given IP address as above.
+
+This is the main class in this package.
+Because it implements ReactPHP's standard
+[`ConnectorInterface`](https://github.com/reactphp/socket#connectorinterface),
+it can simply be used in place of a normal connector.
+Accordingly, it provides only a single public method, the
+[`connect()`](https://github.com/reactphp/socket#connect) method.
+The `connect(string $uri): PromiseInterface<ConnectionInterface, Exception>`
+method can be used to establish a streaming connection.
+It returns a [Promise](https://github.com/reactphp/promise) which either
+fulfills with a [ConnectionInterface](https://github.com/reactphp/socket#connectioninterface)
+on success or rejects with an `Exception` on error.
+
+This makes it fairly simple to add HTTP CONNECT proxy support to pretty much any
+higher-level component:
+
+```diff
+- $client = new SomeClient($connector);
++ $proxy = new ProxyConnector('http://127.0.0.1:8080', $connector);
++ $client = new SomeClient($proxy);
+```
+
+#### Plain TCP connections
+
+HTTP CONNECT proxies are most frequently used to issue HTTPS requests to your destination.
+However, this is actually performed on a higher protocol layer and this
+connector is actually inherently a general-purpose plain TCP/IP connector.
+As documented above, you can simply invoke its `connect()` method to establish
+a streaming plain TCP/IP connection and use any higher level protocol like so:
+
+```php
+$proxy = new ProxyConnector('http://127.0.0.1:8080', $connector);
+
+$proxy->connect('tcp://smtp.googlemail.com:587')->then(function (ConnectionInterface $stream) {
+    $stream->write("EHLO local\r\n");
+    $stream->on('data', function ($chunk) use ($stream) {
+        echo $chunk;
+    });
+});
+```
+
+You can either use the `ProxyConnector` directly or you may want to wrap this connector
+in ReactPHP's [`Connector`](https://github.com/reactphp/socket#connector):
+
+```php
+$connector = new Connector($loop, array(
+    'tcp' => $proxy,
+    'dns' => false
+));
+
+$connector->connect('tcp://smtp.googlemail.com:587')->then(function (ConnectionInterface $stream) {
+    $stream->write("EHLO local\r\n");
+    $stream->on('data', function ($chunk) use ($stream) {
+        echo $chunk;
+    });
+});
+```
+
+Note that HTTP CONNECT proxies often restrict which ports one may connect to.
+Many (public) proxy servers do in fact limit this to HTTPS (443) only.
+
+#### Secure TLS connections
+
+This class can also be used if you want to establish a secure TLS connection
+(formerly known as SSL) between you and your destination, such as when using
+secure HTTPS to your destination site. You can simply wrap this connector in
+ReactPHP's [`Connector`](https://github.com/reactphp/socket#connector) or the
+low-level [`SecureConnector`](https://github.com/reactphp/socket#secureconnector):
+
+```php
+$proxy = new ProxyConnector('http://127.0.0.1:8080', $connector);
+$connector = new Connector($loop, array(
+    'tcp' => $proxy,
+    'dns' => false
+));
+
+$connector->connect('tls://smtp.googlemail.com:465')->then(function (ConnectionInterface $stream) {
+    $stream->write("EHLO local\r\n");
+    $stream->on('data', function ($chunk) use ($stream) {
+        echo $chunk;
+    });
+});
+```
+
+> Note how secure TLS connections are in fact entirely handled outside of
+  this HTTP CONNECT client implementation.
+
+#### Connection timeout
+
+By default, the `ProxyConnector` does not implement any timeouts for establishing remote
+connections.
+Your underlying operating system may impose limits on pending and/or idle TCP/IP
+connections, anywhere in a range of a few minutes to several hours.
+
+Many use cases require more control over the timeout and likely values much
+smaller, usually in the range of a few seconds only.
+
+You can use ReactPHP's [`Connector`](https://github.com/reactphp/socket#connector)
+or the low-level
+[`TimeoutConnector`](https://github.com/reactphp/socket#timeoutconnector)
+to decorate any given `ConnectorInterface` instance.
+It provides the same `connect()` method, but will automatically reject the
+underlying connection attempt if it takes too long:
+
+```php
+$connector = new Connector($loop, array(
+    'tcp' => $proxy,
+    'dns' => false,
+    'timeout' => 3.0
+));
+
+$connector->connect('tcp://google.com:80')->then(function ($stream) {
+    // connection succeeded within 3.0 seconds
+});
+```
+
+See also any of the [examples](examples).
+
+> Note how connection timeout is in fact entirely handled outside of this
+  HTTP CONNECT client implementation.
+
+#### DNS resolution
+
+By default, the `ProxyConnector` does not perform any DNS resolution at all and simply
+forwards any hostname you're trying to connect to the remote proxy server.
+The remote proxy server is thus responsible for looking up any hostnames via DNS
+(this default mode is thus called *remote DNS resolution*).
+
+As an alternative, you can also send the destination IP to the remote proxy
+server.
+In this mode you either have to stick to using IPs only (which is ofen unfeasable)
+or perform any DNS lookups locally and only transmit the resolved destination IPs
+(this mode is thus called *local DNS resolution*).
+
+The default *remote DNS resolution* is useful if your local `ProxyConnector` either can
+not resolve target hostnames because it has no direct access to the internet or
+if it should not resolve target hostnames because its outgoing DNS traffic might
+be intercepted.
+
+As noted above, the `ProxyConnector` defaults to using remote DNS resolution.
+However, wrapping the `ProxyConnector` in ReactPHP's
+[`Connector`](https://github.com/reactphp/socket#connector) actually
+performs local DNS resolution unless explicitly defined otherwise.
+Given that remote DNS resolution is assumed to be the preferred mode, all
+other examples explicitly disable DNS resoltion like this:
+
+```php
+$connector = new Connector($loop, array(
+    'tcp' => $proxy,
+    'dns' => false
+));
+```
+
+If you want to explicitly use *local DNS resolution*, you can use the following code:
+
+```php
+// set up Connector which uses Google's public DNS (8.8.8.8)
+$connector = Connector($loop, array(
+    'tcp' => $proxy,
+    'dns' => '8.8.8.8'
+));
+```
+
+> Note how local DNS resolution is in fact entirely handled outside of this
+  HTTP CONNECT client implementation.
+
+#### Authentication
+
+If your HTTP proxy server requires authentication, you may pass the username and
+password as part of the HTTP proxy URL like this:
+
+```php
+$proxy = new ProxyConnector('http://user:pass@127.0.0.1:8080', $connector);
+```
+
+Note that both the username and password must be percent-encoded if they contain
+special characters:
+
+```php
+$user = 'he:llo';
+$pass = 'p@ss';
+
+$proxy = new ProxyConnector(
+    rawurlencode($user) . ':' . rawurlencode($pass) . '@127.0.0.1:8080',
+    $connector
+);
+```
+
+> The authentication details will be used for basic authentication and will be
+  transferred in the `Proxy-Authorization` HTTP request header for each
+  connection attempt.
+  If the authentication details are missing or not accepted by the remote HTTP
+  proxy server, it is expected to reject each connection attempt with a
+  `407` (Proxy Authentication Required) response status code and an exception
+  error code of `SOCKET_EACCES` (13).
+
+#### Advanced secure proxy connections
+
+Note that communication between the client and the proxy is usually via an
+unencrypted, plain TCP/IP HTTP connection. Note that this is the most common
+setup, because you can still establish a TLS connection between you and the
+destination host as above.
+
+If you want to connect to a (rather rare) HTTPS proxy, you may want use the
+`https://` scheme (HTTPS default port 443) and use ReactPHP's
+[`Connector`](https://github.com/reactphp/socket#connector) or the low-level
+[`SecureConnector`](https://github.com/reactphp/socket#secureconnector)
+instance to create a secure connection to the proxy:
+
+```php
+$connector = new Connector($loop);
+$proxy = new ProxyConnector('https://127.0.0.1:443', $connector);
+
+$proxy->connect('tcp://smtp.googlemail.com:587');
+```
+
+#### Advanced Unix domain sockets
+
+HTTP CONNECT proxy servers support forwarding TCP/IP based connections and
+higher level protocols.
+In some advanced cases, it may be useful to let your HTTP CONNECT proxy server
+listen on a Unix domain socket (UDS) path instead of a IP:port combination.
+For example, this allows you to rely on file system permissions instead of
+having to rely on explicit [authentication](#authentication).
+
+You can simply use the `http+unix://` URI scheme like this:
+
+```php
+$proxy = new ProxyConnector('http+unix:///tmp/proxy.sock', $connector);
+
+$proxy->connect('tcp://google.com:80')->then(function (ConnectionInterface $stream) {
+    // connected…
+});
+```
+
+Similarly, you can also combine this with [authentication](#authentication)
+like this:
+
+```php
+$proxy = new ProxyConnector('http+unix://user:pass@/tmp/proxy.sock', $connector);
+```
+
+> Note that Unix domain sockets (UDS) are considered advanced usage and PHP only
+  has limited support for this.
+  In particular, enabling [secure TLS](#secure-tls-connections) may not be
+  supported.
+
+> Note that the HTTP CONNECT protocol does not support the notion of UDS paths.
+  The above works reasonably well because UDS is only used for the connection between
+  client and proxy server and the path will not actually passed over the protocol.
+  This implies that this does not support connecting to UDS destination paths.
+
+## Install
+
+The recommended way to install this library is [through Composer](https://getcomposer.org).
+[New to Composer?](https://getcomposer.org/doc/00-intro.md)
+
+This project follows [SemVer](http://semver.org/).
+This will install the latest supported version:
+
+```bash
+$ composer require clue/http-proxy-react:^1.3
+```
+
+See also the [CHANGELOG](CHANGELOG.md) for details about version upgrades.
+
+This project aims to run on any platform and thus does not require any PHP
+extensions and supports running on legacy PHP 5.3 through current PHP 7+ and
+HHVM.
+It's *highly recommended to use PHP 7+* for this project.
+
+## Tests
+
+To run the test suite, you first need to clone this repo and then install all
+dependencies [through Composer](https://getcomposer.org):
+
+```bash
+$ composer install
+```
+
+To run the test suite, go to the project root and run:
+
+```bash
+$ php vendor/bin/phpunit
+```
+
+The test suite contains tests that rely on a working internet connection,
+alternatively you can also run it like this:
+
+```bash
+$ php vendor/bin/phpunit --exclude-group internet
+```

+## More
+
+* If you want to learn more about how the
+  [`ConnectorInterface`](https://github.com/reactphp/socket#connectorinterface)
+  and its usual implementations look like, refer to the documentation of the underlying
+  [react/socket](https://github.com/reactphp/socket) component.
+* If you want to learn more about processing streams of data, refer to the
+  documentation of the underlying
+  [react/stream](https://github.com/reactphp/stream) component.
+* As an alternative to an HTTP CONNECT proxy, you may also want to look into
+  using a SOCKS (SOCKS4/SOCKS5) proxy instead.
+  You may want to use [clue/socks-react](https://github.com/clue/php-socks-react)
+  which also provides an implementation of the same
+  [`ConnectorInterface`](https://github.com/reactphp/socket#connectorinterface)
+  so that supporting either proxy protocol should be fairly trivial.
+* If you're dealing with public proxies, you'll likely have to work with mixed
+  quality and unreliable proxies. You may want to look into using
+  [clue/connection-manager-extra](https://github.com/clue/php-connection-manager-extra)
+  which allows retrying unreliable ones, implying connection timeouts,
+  concurrently working with multiple connectors and more.
+* If you're looking for an end-user HTTP CONNECT proxy server daemon, you may
+  want to use [LeProxy](https://leproxy.org/).

+      class name `Clue\React\Socks\Server` with no other changes required.
+
+## 0.7.0 (2017-04-14)
+
+*   Feature / BC break: Replace depreacted SocketClient with Socket v0.7 and
+    use `connect($uri)` instead of `create($host, $port)`
+    (#51 by @clue)
+
+    ```php
+    // old
+    $connector = new React\SocketClient\TcpConnector($loop);
+    $client = new Client(1080, $connector);
+    $client->create('google.com', 80)->then(function (Stream $conn) {
+        $conn->write("…");
+    });
+
+    // new
+    $connector = new React\Socket\TcpConnector($loop);
+    $client = new Client(1080, $connector);

+*   Improve test suite by adding PHPUnit to require-dev
+    (#50 by @clue)
+
+## 0.6.0 (2016-11-29)
+
+* Feature / BC break: Pass connector into `Client` instead of loop, remove unneeded deps
+  (#49 by @clue)
+
+  ```php
+  // old (connector is create implicitly)
+  $client = new Client('127.0.0.1', $loop);
+
+  // old (connector can optionally be passed)
+  $client = new Client('127.0.0.1', $loop, $connector);
+
+  // new (connector is now mandatory)
+  $connector = new React\SocketClient\TcpConnector($loop);
+  $client = new Client('127.0.0.1', $connector);
+  ```
+
+* Feature / BC break: `Client` now implements `ConnectorInterface`, remove `Connector` adapter
+  (#47 by @clue)
+
+  ```php
+  // old (explicit connector functions as an adapter)
+  $connector = $client->createConnector();
+  $promise = $connector->create('google.com', 80);
+
+  // new (client can be used as connector right away)
+  $promise = $client->create('google.com', 80);
+  ```
+
+* Feature / BC break: Remove `createSecureConnector()`, use `SecureConnector` instead
+  (#47 by @clue)
+
+  ```php
+  // old (tight coupling and hidden dependency)
+  $tls = $client->createSecureConnector();
+  $promise = $tls->create('google.com', 443);
+
+  // new (more explicit, loose coupling)
+  $tls = new React\SocketClient\SecureConnector($client, $loop);
+  $promise = $tls->create('google.com', 443);
+  ```
+
+* Feature / BC break: Remove `setResolveLocal()` and local DNS resolution and default to remote DNS resolution, use `DnsConnector` instead
+  (#44 by @clue)
+
+  ```php
+  // old (implicitly defaults to true, can be disabled)
+  $client->setResolveLocal(false);
+  $tcp = $client->createConnector();
+  $promise = $tcp->create('google.com', 80);
+
+  // new (always disabled, can be re-enabled like this)
+  $factory = new React\Dns\Resolver\Factory();
+  $resolver = $factory->createCached('8.8.8.8', $loop);
+  $tcp = new React\SocketClient\DnsConnector($client, $resolver);
+  $promise = $tcp->create('google.com', 80);
+  ```
+
+* Feature / BC break: Remove `setTimeout()`, use `TimeoutConnector` instead
+  (#45 by @clue)
+
+  ```php
+  // old (timeout only applies to TCP/IP connection)
+  $client = new Client('127.0.0.1', …);
+  $client->setTimeout(3.0);
+  $tcp = $client->createConnector();
+  $promise = $tcp->create('google.com', 80);
+
+  // new (timeout can be added to any layer)
+  $client = new Client('127.0.0.1', …);
+  $tcp = new React\SocketClient\TimeoutConnector($client, 3.0, $loop);
+  $promise = $tcp->create('google.com', 80);
+  ```
+
+* Feature / BC break: Remove `setProtocolVersion()` and `setAuth()` mutators, only support SOCKS URI for protocol version and authentication (immutable API)
+  (#46 by @clue)
+
+  ```php
+  // old (state can be mutated after instantiation)
+  $client = new Client('127.0.0.1', …);
+  $client->setProtocolVersion('5');
+  $client->setAuth('user', 'pass');
+
+  // new (immutable after construction, already supported as of v0.5.2 - now mandatory)
+  $client = new Client('socks5://user:pass@127.0.0.1', …);
+  ```
+
+## 0.5.2 (2016-11-25)
+
+* Feature: Apply protocol version and username/password auth from SOCKS URI
+  (#43 by @clue)
+
+  ```php
+  // explicitly use SOCKS5
+  $client = new Client('socks5://127.0.0.1', $loop);
+
+  // use authentication (automatically SOCKS5)
+  $client = new Client('user:pass@127.0.0.1', $loop);
+  ```
+
+* More explicit client examples, including proxy chaining
+  (#42 by @clue)
+
+## 0.5.1 (2016-11-21)
+
+* Feature: Support Promise cancellation
+  (#39 by @clue)
+
+  ```php
+  $promise = $connector->create($host, $port);
+
+  $promise->cancel();
+  ```
+
+* Feature: Timeout now cancels pending connection attempt
+  (#39, #22 by @clue)
+
+## 0.5.0 (2016-11-07)
+
+* Remove / BC break: Split off Server to clue/socks-server
+  (#35 by @clue)
+
+  > Upgrading? Check [clue/socks-server](https://github.com/clue/php-socks-server) for details.
+
+* Improve documentation and project structure
+
+## 0.4.0 (2016-03-19)
+
+* Feature: Support proper SSL/TLS connections with additional SSL context options
+  (#31, #33 by @clue)
+
+* Documentation for advanced Connector setups (bindto, multihop)
+  (#32 by @clue)
+
+## 0.3.0 (2015-06-20)
+
+* BC break / Feature: Client ctor now accepts a SOCKS server URI
+  ([#24](https://github.com/clue/php-socks-react/pull/24))
+  
+    ```php
+// old
+$client = new Client($loop, 'localhost', 9050);
+
+// new
+$client = new Client('localhost:9050', $loop);
+```
+
+* Feature: Automatically assume default SOCKS port (1080) if not given explicitly
+  ([#26](https://github.com/clue/php-socks-react/pull/26))
+
+* Improve documentation and test suite
+
+## 0.2.1 (2014-11-13)
+
+* Support React PHP v0.4 (while preserving BC with React PHP v0.3)
+  ([#16](https://github.com/clue/php-socks-react/pull/16))
+
+* Improve examples and add first class support for HHVM
+  ([#15](https://github.com/clue/php-socks-react/pull/15) and [#17](https://github.com/clue/php-socks-react/pull/17))
+
+## 0.2.0 (2014-09-27)
+
+* BC break / Feature: Simplify constructors by making parameters optional.
+  ([#10](https://github.com/clue/php-socks-react/pull/10))
+  
+  The `Factory` has been removed, you can now create instances of the `Client`
+  and `Server` yourself:
+  
+  ```php
+  // old
+  $factory = new Factory($loop, $dns);
+  $client = $factory->createClient('localhost', 9050);
+  $server = $factory->createSever($socket);
+  
+  // new
+  $client = new Client($loop, 'localhost', 9050);
+  $server = new Server($loop, $socket);
+  ```
+
+* BC break: Remove HTTP support and link to [clue/buzz-react](https://github.com/clue/php-buzz-react) instead.
+  ([#9](https://github.com/clue/php-socks-react/pull/9))
+  
+  HTTP operates on a different layer than this low-level SOCKS library.
+  Removing this reduces the footprint of this library.
+  
+  > Upgrading? Check the [README](https://github.com/clue/php-socks-react#http-requests) for details.  
+
+* Fix: Refactored to support other, faster loops (libev/libevent)
+  ([#12](https://github.com/clue/php-socks-react/pull/12))
+
+* Explicitly list dependencies, clean up examples and extend test suite significantly
+
+## 0.1.0 (2014-05-19)
+
+* First stable release
+* Async SOCKS `Client` and `Server` implementation
+* Project was originally part of [clue/socks](https://github.com/clue/php-socks)
+  and was split off from its latest releave v0.4.0
+  ([#1](https://github.com/clue/reactphp-socks/issues/1))
+
+> Upgrading from clue/socks v0.4.0? Use namespace `Clue\React\Socks` instead of `Socks` and you're ready to go!
+
+## 0.0.0 (2011-04-26)
+
+* Initial concept, originally tracked as part of
+  [clue/socks](https://github.com/clue/php-socks)

+## Quickstart example
+
+Once [installed](#install), you can use the following code to create a connection
+to google.com via a local SOCKS proxy server:
+
+```php
+$loop = React\EventLoop\Factory::create();
+$client = new Client('127.0.0.1:1080', new Connector($loop));
+
+$client->connect('tcp://www.google.com:80')->then(function (ConnectionInterface $stream) {
+    $stream->write("GET / HTTP/1.0\r\n\r\n");
+});
+
+$loop->run();
+```
+
+If you're not already running any other [SOCKS proxy server](#servers),
+you can use the following code to create a SOCKS
+proxy server listening for connections on `localhost:1080`:
+
+```php
+$loop = React\EventLoop\Factory::create();
+
+// listen on localhost:1080
+$socket = new Socket('127.0.0.1:1080', $loop);
+
+// start a new server listening for incoming connection on the given socket
+$server = new Server($loop, $socket);
+
+$loop->run();
+```
+
+See also the [examples](examples).
+
+## Usage
+
+### ConnectorInterface
+
+The `ConnectorInterface` is responsible for providing an interface for
+establishing streaming connections, such as a normal TCP/IP connection.
+
+In order to use this library, you should understand how this integrates with its
+ecosystem.
+This base interface is actually defined in React's
+[Socket component](https://github.com/reactphp/socket) and used
+throughout React's ecosystem.
+
+Most higher-level components (such as HTTP, database or other networking
+service clients) accept an instance implementing this interface to create their
+TCP/IP connection to the underlying networking service.
+This is usually done via dependency injection, so it's fairly simple to actually
+swap this implementation against this library in order to connect through a
+SOCKS proxy server.
+
+The interface only offers a single method:
+
+#### connect()
+
+The `connect(string $uri): PromiseInterface<ConnectionInterface, Exception>` method
+can be used to establish a streaming connection.
+It returns a [Promise](https://github.com/reactphp/promise) which either
+fulfills with a [ConnectionInterface](https://github.com/reactphp/socket#connectioninterface) or
+rejects with an `Exception`:
+
+```php
+$connector->connect('tcp://google.com:80')->then(
+    function (ConnectionInterface $stream) {
+        // connection successfully established
+    },
+    function (Exception $error) {
+        // failed to connect due to $error
+    }
+);
+```
+
+### Client
+
+The `Client` is responsible for communication with your SOCKS server instance.
+Its constructor simply accepts an SOCKS proxy URI and a connector used to
+connect to the SOCKS proxy server address.
+
+In its most simple form, you can simply pass React's
+[`Connector`](https://github.com/reactphp/socket#connector)
+like this:
+
+```php
+$connector = new React\Socket\Connector($loop);
+$client = new Client('127.0.0.1:1080', $connector);
+```
+
+You can omit the port if you're using the default SOCKS port 1080:
+
+```php
+$client = new Client('127.0.0.1', $connector);
+```
+
+If you need custom connector settings (DNS resolution, timeouts etc.), you can explicitly pass a
+custom instance of the [`ConnectorInterface`](https://github.com/reactphp/socket#connectorinterface):
+
+```php
+// use local DNS server
+$dnsResolverFactory = new DnsFactory();
+$resolver = $dnsResolverFactory->createCached('127.0.0.1', $loop);
+
+// outgoing connections to SOCKS server via interface 192.168.10.1
+// this is not to be confused with local DNS resolution (see further below)
+$connector = new DnsConnector(
+    new TcpConnector($loop, array('bindto' => '192.168.10.1:0')),
+    $resolver
+);
+
+$client = new Client('my-socks-server.local:1080', $connector);
+```
+
+This is the main class in this package.
+Because it implements the the [`ConnectorInterface`](#connectorinterface), it
+can simply be used in place of a normal connector.
+This makes it fairly simple to add SOCKS proxy support to pretty much any
+higher-level component:
+
+```diff
+- $client = new SomeClient($connector);
++ $proxy = new Client('127.0.0.1:1080', $connector);
++ $client = new SomeClient($proxy);
+```
+
+#### Plain TCP connections
+
+The `Client` implements the [`ConnectorInterface`](#connectorinterface) and
+hence provides a single public method, the [`connect()`](#connect) method.
+Let's open up a streaming TCP/IP connection and write some data:
+
+```php
+$client->connect('tcp://www.google.com:80')->then(function (ConnectonInterface $stream) {
+    echo 'connected to www.google.com:80';
+    $stream->write("GET / HTTP/1.0\r\n\r\n");
+    // ...
+});
+```
+
+You can either use the `Client` directly or you may want to wrap this connector
+in React's [`Connector`](https://github.com/reactphp/socket#connector):
+
+```php
+$connector = new React\Socket\Connector($loop, array(
+    'tcp' => $client,
+    'dns' => false
+));
+
+$connector->connect('tcp://www.google.com:80')->then(function (ConnectonInterface $stream) {
+    echo 'connected to www.google.com:80';
+    $stream->write("GET / HTTP/1.0\r\n\r\n");
+    // ...
+});
+
+```
+
+See also the [first example](examples).
+
+The `tcp://` scheme can also be omitted.
+Passing any other scheme will reject the promise.
+
+Pending connection attempts can be canceled by canceling its pending promise like so:
+
+```php
+$promise = $connector->connect($uri);
+
+$promise->cancel();
+```
+
+Calling `cancel()` on a pending promise will cancel the underlying TCP/IP
+connection to the SOCKS server and/or the SOCKS protocol negotiation and reject
+the resulting promise.
+
+#### Secure TLS connections
+
+If you want to establish a secure TLS connection (such as HTTPS) between you and
+your destination, you may want to wrap this connector in React's
+[`Connector`](https://github.com/reactphp/socket#connector) or the low-level
+[`SecureConnector`](https://github.com/reactphp/socket#secureconnector):
+
+```php
+$connector = new React\Socket\Connector($loop, array(
+    'tcp' => $client,
+    'dns' => false
+));
+
+// now create an SSL encrypted connection (notice the $ssl instead of $tcp)
+$connector->connect('tls://www.google.com:443')->then(function (ConnectionInterface $stream) {
+    // proceed with just the plain text data
+    // everything is encrypted/decrypted automatically
+    echo 'connected to SSL encrypted www.google.com';
+    $stream->write("GET / HTTP/1.0\r\n\r\n");
+    // ...
+});
+```
+
+See also the [second example](examples).
+
+If you use the low-level `SecureConnector`, then the `tls://` scheme can also
+be omitted.
+Passing any other scheme will reject the promise.
+
+Pending connection attempts can be canceled by canceling its pending promise
+as usual.
+
+> Also note how secure TLS connections are in fact entirely handled outside of
+  this SOCKS client implementation.
+
+You can optionally pass additional
+[SSL context options](http://php.net/manual/en/context.ssl.php)
+to the constructor like this:
+
+```php
+$connector = new React\Socket\Connector($loop, array(
+    'tcp' => $client,
+    'tls' => array(
+        'verify_peer' => false,
+        'verify_peer_name' => false
+    ),
+    'dns' => false
+));
+```
+
+#### HTTP requests
+
+HTTP operates on a higher layer than this low-level SOCKS implementation.
+If you want to issue HTTP requests, you can add a dependency for
+[clue/buzz-react](https://github.com/clue/php-buzz-react).
+It can interact with this library by issuing all
+[http requests through a SOCKS server](https://github.com/clue/php-buzz-react#socks-proxy).
+This works for both plain HTTP and SSL encrypted HTTPS requests.
+
+#### Protocol version
+
+This library supports the SOCKS4, SOCKS4a and SOCKS5 protocol versions.
+
+While SOCKS4 already had (a somewhat limited) support for `SOCKS BIND` requests
+and SOCKS5 added generic UDP support (`SOCKS UDPASSOCIATE`), this library
+focuses on the most commonly used core feature of `SOCKS CONNECT`.
+In this mode, a SOCKS server acts as a generic proxy allowing higher level
+application protocols to work through it.

+</table>
+
+Note, this is __not__ a full SOCKS5 implementation due to missing GSSAPI
+authentication (but it's unlikely you're going to miss it anyway).
+
+By default, the `Client` communicates via SOCKS4a with the SOCKS server
+– unless you enable [authentication](#authentication), in which case it will
+default to SOCKS5.
+This is done because SOCKS4a incurs less overhead than SOCKS5 (see above) and
+is equivalent with SOCKS4 if you use [local DNS resolution](#dns-resolution).
+
+If want to explicitly set the protocol version, use the supported values URI
+schemes `socks4`, `socks4a` or `socks5` as part of the SOCKS URI:
+
+```php
+$client = new Client('socks5://127.0.0.1', $connector);
+```
+
+As seen above, both SOCKS5 and SOCKS4a support remote and local DNS resolution.
+If you've explicitly set this to SOCKS4, then you may want to check the following
+chapter about local DNS resolution or you may only connect to IPv4 addresses.
+
+#### DNS resolution
+
+By default, the `Client` does not perform any DNS resolution at all and simply
+forwards any hostname you're trying to connect to to the SOCKS server.
+The remote SOCKS server is thus responsible for looking up any hostnames via DNS
+(this default mode is thus called *remote DNS resolution*).
+As seen above, this mode is supported by the SOCKS5 and SOCKS4a protocols, but
+not the SOCKS4 protocol, as the protocol lacks a way to communicate hostnames.
+
+On the other hand, all SOCKS protocol versions support sending destination IP
+addresses to the SOCKS server.
+In this mode you either have to stick to using IPs only (which is ofen unfeasable)
+or perform any DNS lookups locally and only transmit the resolved destination IPs
+(this mode is thus called *local DNS resolution*).
+
+The default *remote DNS resolution* is useful if your local `Client` either can
+not resolve target hostnames because it has no direct access to the internet or
+if it should not resolve target hostnames because its outgoing DNS traffic might
+be intercepted (in particular when using the
+[Tor network](#using-the-tor-anonymity-network-to-tunnel-socks-connections)).
+
+As noted above, the `Client` defaults to using remote DNS resolution.
+However, wrapping the `Client` in React's
+[`Connector`](https://github.com/reactphp/socket#connector) actually
+performs local DNS resolution unless explicitly defined otherwise.
+Given that remote DNS resolution is assumed to be the preferred mode, all
+other examples explicitly disable DNS resoltion like this:
+
+```php
+$connector = new React\Socket\Connector($loop, array(
+    'tcp' => $client,
+    'dns' => false
+));
+```
+
+If you want to explicitly use *local DNS resolution* (such as when explicitly
+using SOCKS4), you can use the following code:
+
+```php
+// set up Connector which uses Google's public DNS (8.8.8.8)
+$connector = new React\Socket\Connector($loop, array(
+    'tcp' => $client,
+    'dns' => '8.8.8.8'
+));
+```
+
+See also the [fourth example](examples).
+
+Pending connection attempts can be canceled by canceling its pending promise
+as usual.
+
+> Also note how local DNS resolution is in fact entirely handled outside of this
+  SOCKS client implementation.
+
+If you've explicitly set the client to SOCKS4 and stick to the default
+*remote DNS resolution*, then you may only connect to IPv4 addresses because
+the protocol lacks a way to communicate hostnames.
+If you try to connect to a hostname despite, the resulting promise will be
+rejected right away.
+
+#### Authentication
+
+This library supports username/password authentication for SOCKS5 servers as
+defined in [RFC 1929](http://tools.ietf.org/html/rfc1929).
+
+On the client side, simply pass your username and password to use for
+authentication (see below).
+For each further connection the client will merely send a flag to the server
+indicating authentication information is available.
+Only if the server requests authentication during the initial handshake,
+the actual authentication credentials will be transmitted to the server.
+
+Note that the password is transmitted in cleartext to the SOCKS proxy server,
+so this methods should not be used on a network where you have to worry about eavesdropping.
+
+You can simply pass the authentication information as part of the SOCKS URI:
+
+```php
+$client = new Client('username:password@127.0.0.1', $connector);
+```
+
+Note that both the username and password must be percent-encoded if they contain
+special characters:
+
+```php
+$user = 'he:llo';
+$pass = 'p@ss';
+
+$client = new Client(
+    rawurlencode($user) . ':' . rawurlencode($pass) . '@127.0.0.1',
+    $connector
+);
+```
+
+> The authentication details will be transmitted in cleartext to the SOCKS proxy
+  server only if it requires username/password authentication.
+  If the authentication details are missing or not accepted by the remote SOCKS
+  proxy server, it is expected to reject each connection attempt with an
+  exception error code of `SOCKET_EACCES` (13).
+
+Authentication is only supported by protocol version 5 (SOCKS5),
+so passing authentication to the `Client` enforces communication with protocol
+version 5 and complains if you have explicitly set anything else:
+
+```php
+// throws InvalidArgumentException
+new Client('socks4://user:pass@127.0.0.1', $connector);
+```
+
+#### Proxy chaining
+
+The `Client` is responsible for creating connections to the SOCKS server which
+then connects to the target host.
+
+```
+Client -> SocksServer -> TargetHost
+```
+
+Sometimes it may be required to establish outgoing connections via another SOCKS
+server.
+For example, this can be useful if you want to conceal your origin address.
+
+```
+Client -> MiddlemanSocksServer -> TargetSocksServer -> TargetHost
+```
+
+The `Client` uses any instance of the `ConnectorInterface` to establish
+outgoing connections.
+In order to connect through another SOCKS server, you can simply use another
+SOCKS connector from another SOCKS client like this:
+
+```php
+// https via the proxy chain  "MiddlemanSocksServer -> TargetSocksServer -> TargetHost"
+// please note how the client uses TargetSocksServer (not MiddlemanSocksServer!),
+// which in turn then uses MiddlemanSocksServer.
+// this creates a TCP/IP connection to MiddlemanSocksServer, which then connects
+// to TargetSocksServer, which then connects to the TargetHost
+$middle = new Client('127.0.0.1:1080', new Connector($loop));
+$target = new Client('example.com:1080', $middle);
+
+$connector = new React\Socket\Connector($loop, array(
+    'tcp' => $target,
+    'dns' => false
+));
+
+$connector->connect('tls://www.google.com:443')->then(function ($stream) {
+    // …
+});
+```
+
+See also the [third example](examples).
+
+Pending connection attempts can be canceled by canceling its pending promise
+as usual.
+
+Proxy chaining can happen on the server side and/or the client side:
+
+* If you ask your client to chain through multiple proxies, then each proxy
+  server does not really know anything about chaining at all.
+  This means that this is a client-only property.
+
+* If you ask your server to chain through another proxy, then your client does
+  not really know anything about chaining at all.
+  This means that this is a server-only property and not part of this class.
+  For example, you can find this in the below [`Server`](#server-proxy-chaining)
+  class or somewhat similar when you're using the
+  [Tor network](#using-the-tor-anonymity-network-to-tunnel-socks-connections).
+
+#### Connection timeout
+
+By default, the `Client` does not implement any timeouts for establishing remote
+connections.
+Your underlying operating system may impose limits on pending and/or idle TCP/IP
+connections, anywhere in a range of a few minutes to several hours.
+
+Many use cases require more control over the timeout and likely values much
+smaller, usually in the range of a few seconds only.
+
+You can use React's [`Connector`](https://github.com/reactphp/socket#connector)
+or the low-level
+[`TimeoutConnector`](https://github.com/reactphp/socket#timeoutconnector)
+to decorate any given `ConnectorInterface` instance.
+It provides the same `connect()` method, but will automatically reject the
+underlying connection attempt if it takes too long:
+
+```php
+$connector = new Connector($loop, array(
+    'tcp' => $client,
+    'dns' => false,
+    'timeout' => 3.0
+));
+
+$connector->connect('tcp://google.com:80')->then(function ($stream) {
+    // connection succeeded within 3.0 seconds
+});
+```
+
+See also any of the [examples](examples).
+
+Pending connection attempts can be canceled by canceling its pending promise
+as usual.
+
+> Also note how connection timeout is in fact entirely handled outside of this
+  SOCKS client implementation.
+
+#### SOCKS over TLS
+
+All [SOCKS protocol versions](#protocol-version) support forwarding TCP/IP
+based connections and higher level protocols.
+This implies that you can also use [secure TLS connections](#secure-tls-connections)
+to transfer sensitive data across SOCKS proxy servers.
+This means that no eavesdropper nor the proxy server will be able to decrypt
+your data.
+
+However, the initial SOCKS communication between the client and the proxy is
+usually via an unencrypted, plain TCP/IP connection.
+This means that an eavesdropper may be able to see *where* you connect to and
+may also be able to see your [SOCKS authentication](#authentication) details
+in cleartext.
+
+As an alternative, you may establish a secure TLS connection to your SOCKS
+proxy before starting the initial SOCKS communication.
+This means that no eavesdroppper will be able to see the destination address
+you want to connect to or your [SOCKS authentication](#authentication) details.
+
+You can use the `sockss://` URI scheme or use an explicit
+[SOCKS protocol version](#protocol-version) like this:
+
+```php
+$client = new Client('sockss://127.0.0.1:1080', new Connector($loop));
+
+$client = new Client('socks5s://127.0.0.1:1080', new Connector($loop));
+```
+
+See also [example 32](examples).
+
+Simiarly, you can also combine this with [authentication](#authentication)
+like this:
+
+```php
+$client = new Client('sockss://user:pass@127.0.0.1:1080', new Connector($loop));
+```
+
+> Note that for most use cases, [secure TLS connections](#secure-tls-connections)
+  should be used instead. SOCKS over TLS is considered advanced usage and is
+  used very rarely in practice.
+  In particular, the SOCKS server has to accept secure TLS connections, see
+  also [Server SOCKS over TLS](#server-socks-over-tls) for more details.
+  Also, PHP does not support "double encryption" over a single connection.
+  This means that enabling [secure TLS connections](#secure-tls-connections)
+  over a communication channel that has been opened with SOCKS over TLS
+  may not be supported.
+
+> Note that the SOCKS protocol does not support the notion of TLS. The above
+  works reasonably well because TLS is only used for the connection between
+  client and proxy server and the SOCKS protocol data is otherwise identical.
+  This implies that this may also have only limited support for
+  [proxy chaining](#proxy-chaining) over multiple TLS paths.
+
+#### Unix domain sockets
+
+All [SOCKS protocol versions](#protocol-version) support forwarding TCP/IP
+based connections and higher level protocols.
+In some advanced cases, it may be useful to let your SOCKS server listen on a
+Unix domain socket (UDS) path instead of a IP:port combination.
+For example, this allows you to rely on file system permissions instead of
+having to rely on explicit [authentication](#authentication).
+
+You can use the `socks+unix://` URI scheme or use an explicit
+[SOCKS protocol version](#protocol-version) like this:
+
+```php
+$client = new Client('socks+unix:///tmp/proxy.sock', new Connector($loop));
+
+$client = new Client('socks5+unix:///tmp/proxy.sock', new Connector($loop));
+```
+
+Simiarly, you can also combine this with [authentication](#authentication)
+like this:
+
+```php
+$client = new Client('socks+unix://user:pass@/tmp/proxy.sock', new Connector($loop));
+```
+
+> Note that Unix domain sockets (UDS) are considered advanced usage and PHP only
+  has limited support for this.
+  In particular, enabling [secure TLS](#secure-tls-connections) may not be
+  supported.
+
+> Note that SOCKS protocol does not support the notion of UDS paths. The above
+  works reasonably well because UDS is only used for the connection between
+  client and proxy server and the path will not actually passed over the protocol.
+  This implies that this does also not support [proxy chaining](#proxy-chaining)
+  over multiple UDS paths.
+
+### Server
+
+The `Server` is responsible for accepting incoming communication from SOCKS clients
+and forwarding the requested connection to the target host.
+It also registers everything with the main [`EventLoop`](https://github.com/reactphp/event-loop#usage)
+and an underlying TCP/IP socket server like this:
+
+```php
+$loop = \React\EventLoop\Factory::create();
+
+// listen on localhost:$port
+$socket = new Socket($port, $loop);
+
+$server = new Server($loop, $socket);
+```
+
+#### Server connector
+
+The `Server` uses an instance of the [`ConnectorInterface`](#connectorinterface)
+to establish outgoing connections for each incoming connection request.
+
+If you need custom connector settings (DNS resolution, timeouts etc.), you can explicitly pass a
+custom instance of the [`ConnectorInterface`](https://github.com/reactphp/socket#connectorinterface):
+
+```php
+// use local DNS server
+$dnsResolverFactory = new DnsFactory();
+$resolver = $dnsResolverFactory->createCached('127.0.0.1', $loop);
+
+// outgoing connections to target host via interface 192.168.10.1
+$connector = new DnsConnector(
+    new TcpConnector($loop, array('bindto' => '192.168.10.1:0')),
+    $resolver
+);
+
+$server = new Server($loop, $socket, $connector);
+```
+
+If you want to forward the outgoing connection through another SOCKS proxy, you
+may also pass a [`Client`](#client) instance as a connector, see also
+[server proxy chaining](#server-proxy-chaining) for more details.
+
+Internally, the `Server` uses the normal [`connect()`](#connect) method, but
+it also passes the original client IP as the `?source={remote}` parameter.
+The `source` parameter contains the full remote URI, including the protocol
+and any authentication details, for example `socks5://user:pass@1.2.3.4:5678`.
+You can use this parameter for logging purposes or to restrict connection
+requests for certain clients by providing a custom implementation of the
+[`ConnectorInterface`](#connectorinterface).
+
+#### Server protocol version
+
+The `Server` supports all protocol versions (SOCKS4, SOCKS4a and SOCKS5) by default.
+
+If want to explicitly set the protocol version, use the supported values `4`, `4a` or `5`:
+
+```PHP
+$server->setProtocolVersion(5);
+```
+
+In order to reset the protocol version to its default (i.e. automatic detection),
+use `null` as protocol version.
+
+```PHP
+$server->setProtocolVersion(null);
+```
+
+#### Server authentication
+
+By default, the `Server` does not require any authentication from the clients.
+You can enable authentication support so that clients need to pass a valid
+username and password before forwarding any connections.
+
+Setting authentication on the `Server` enforces each further connected client
+to use protocol version 5 (SOCKS5).
+If a client tries to use any other protocol version, does not send along
+authentication details or if authentication details can not be verified,
+the connection will be rejected.
+
+Because your authentication mechanism might take some time to actually check
+the provided authentication credentials (like querying a remote database or webservice),
+the server side uses a [Promise](https://github.com/reactphp/promise) based interface.
+While this might seem complex at first, it actually provides a very simple way
+to handle simultanous connections in a non-blocking fashion and increases overall performance.
+
+```PHP
+$server->setAuth(function ($username, $password, $remote) {
+    // either return a boolean success value right away
+    // or use promises for delayed authentication
+
+    // $remote is a full URI à la socks5://user:pass@192.168.1.1:1234
+    // or socks5s://user:pass@192.168.1.1:1234 for SOCKS over TLS
+    // useful for logging or extracting parts, such as the remote IP
+    $ip = parse_url($remote, PHP_URL_HOST);
+
+    return ($username === 'root' && $ip === '127.0.0.1');
+});
+```
+
+Or if you only accept static authentication details, you can use the simple
+array-based authentication method as a shortcut:
+
+```PHP
+$server->setAuthArray(array(
+    'tom' => 'password',
+    'admin' => 'root'
+));
+```
+
+See also [example #12](examples).
+
+If you do not want to use authentication anymore:
+
+```PHP
+$server->unsetAuth();
+```
+
+#### Server proxy chaining
+
+The `Server` is responsible for creating connections to the target host.
+
+```
+Client -> SocksServer -> TargetHost
+```
+
+Sometimes it may be required to establish outgoing connections via another SOCKS
+server.
+For example, this can be useful if your target SOCKS server requires
+authentication, but your client does not support sending authentication
+information (e.g. like most webbrowser).
+
+```
+Client -> MiddlemanSocksServer -> TargetSocksServer -> TargetHost
+```
+
+The `Server` uses any instance of the `ConnectorInterface` to establish outgoing
+connections.
+In order to connect through another SOCKS server, you can simply use the
+[`Client`](#client) SOCKS connector from above.
+You can create a SOCKS `Client` instance like this: 
+
+```php
+// set next SOCKS server example.com:1080 as target
+$connector = new React\Socket\Connector($loop);
+$client = new Client('user:pass@example.com:1080', $connector);
+
+// listen on localhost:1080
+$socket = new Socket('127.0.0.1:1080', $loop);
+
+// start a new server which forwards all connections to the other SOCKS server
+$server = new Server($loop, $socket, $client);
+```
+
+See also [example #21](examples).
+
+Proxy chaining can happen on the server side and/or the client side:
+
+* If you ask your client to chain through multiple proxies, then each proxy
+  server does not really know anything about chaining at all.
+  This means that this is a client-only property and not part of this class.
+  For example, you can find this in the above [`Client`](#proxy-chaining) class.
+
+* If you ask your server to chain through another proxy, then your client does
+  not really know anything about chaining at all.
+  This means that this is a server-only property and can be implemented as above.
+
+#### Server SOCKS over TLS
+
+All [SOCKS protocol versions](#server-protocol-version) support forwarding TCP/IP
+based connections and higher level protocols.
+This implies that you can also use [secure TLS connections](#secure-tls-connections)
+to transfer sensitive data across SOCKS proxy servers.
+This means that no eavesdropper nor the proxy server will be able to decrypt
+your data.
+
+However, the initial SOCKS communication between the client and the proxy is
+usually via an unencrypted, plain TCP/IP connection.
+This means that an eavesdropper may be able to see *where* the client connects
+to and may also be able to see the [SOCKS authentication](#authentication)
+details in cleartext.
+
+As an alternative, you may listen for SOCKS over TLS connections so
+that the client has to establish a secure TLS connection to your SOCKS
+proxy before starting the initial SOCKS communication.
+This means that no eavesdroppper will be able to see the destination address
+the client wants to connect to or their [SOCKS authentication](#authentication)
+details.
+
+You can simply start your listening socket on the `tls://` URI scheme like this:
+
+```php
+$loop = \React\EventLoop\Factory::create();
+
+// listen on tls://127.0.0.1:1080 with the given server certificate
+$socket = new React\Socket\Server('tls://127.0.0.1:1080', $loop, array(
+    'tls' => array(
+        'local_cert' => __DIR__ . '/localhost.pem',
+    )
+));
+$server = new Server($loop, $socket);
+```
+
+See also [example 31](examples).
+
+> Note that for most use cases, [secure TLS connections](#secure-tls-connections)
+  should be used instead. SOCKS over TLS is considered advanced usage and is
+  used very rarely in practice.
+
+> Note that the SOCKS protocol does not support the notion of TLS. The above
+  works reasonably well because TLS is only used for the connection between
+  client and proxy server and the SOCKS protocol data is otherwise identical.
+  This implies that this does also not support [proxy chaining](#server-proxy-chaining)
+  over multiple TLS paths.
+
+#### Server Unix domain sockets
+
+All [SOCKS protocol versions](#server-protocol-version) support forwarding TCP/IP
+based connections and higher level protocols.

+
+```php
+$loop = \React\EventLoop\Factory::create();
+
+// listen on /tmp/proxy.sock
+$socket = new React\Socket\Server('unix:///tmp/proxy.sock', $loop);
+$server = new Server($loop, $socket);
+```
+
+> Note that Unix domain sockets (UDS) are considered advanced usage and that
+  the SOCKS protocol does not support the notion of UDS paths. The above
+  works reasonably well because UDS is only used for the connection between
+  client and proxy server and the path will not actually passed over the protocol.
+  This implies that this does also not support [proxy chaining](#server-proxy-chaining)
+  over multiple UDS paths.
+
+## Servers
+
+### Using a PHP SOCKS server
+
+* If you're looking for an end-user SOCKS server daemon, you may want to use
+  [LeProxy](https://leproxy.org/) or [clue/psocksd](https://github.com/clue/psocksd).
+* If you're looking for a SOCKS server implementation, consider using
+  the above [`Server`](#server) class.
+
+### Using SSH as a SOCKS server
+
+If you already have an SSH server set up, you can easily use it as a SOCKS
+tunnel end point. On your client, simply start your SSH client and use
+the `-D <port>` option to start a local SOCKS server (quoting the man page:
+a `local "dynamic" application-level port forwarding`).
+
+You can start a local SOCKS server by creating a loopback connection to your
+local system if you already run an SSH daemon:
+
+```bash
+$ ssh -D 1080 localhost
+```
+
+Alternatively, you can start a local SOCKS server tunneling through a given
+remote host that runs an SSH daemon:
+
+```bash
+$ ssh -D 1080 example.com
+```
+
+Now you can simply use this SSH SOCKS server like this:
+
+```PHP
+$client = new Client('127.0.0.1:1080', $connector);
+```
+
+Note that the above will allow all users on the local system to connect over
+your SOCKS server without authentication which may or may not be what you need.
+As an alternative, recent OpenSSH client versions also support
+[Unix domain sockets](#unix-domain-sockets) (UDS) paths so that you can rely
+on Unix file system permissions instead:
+
+```bash
+$ ssh -D/tmp/proxy.sock example.com
+```
+
+Now you can simply use this SSH SOCKS server like this:
+
+```PHP
+$client = new Client('socks+unix:///tmp/proxy.sock', $connector);
+```
+
+### Using the Tor (anonymity network) to tunnel SOCKS connections
+
+The [Tor anonymity network](http://www.torproject.org) client software is designed
+to encrypt your traffic and route it over a network of several nodes to conceal its origin.
+It presents a SOCKS4 and SOCKS5 interface on TCP port 9050 by default
+which allows you to tunnel any traffic through the anonymity network.
+In most scenarios you probably don't want your client to resolve the target hostnames,
+because you would leak DNS information to anybody observing your local traffic.
+Also, Tor provides hidden services through an `.onion` pseudo top-level domain
+which have to be resolved by Tor.
+
+```PHP
+$client = new Client('127.0.0.1:9050', $connector);
+```
+
+## Install
+
+The recommended way to install this library is [through Composer](https://getcomposer.org).
+[New to Composer?](https://getcomposer.org/doc/00-intro.md)
+
+This will install the latest supported version:
+
+```bash
+$ composer require clue/socks-react:^0.8.7
+```
+
+See also the [CHANGELOG](CHANGELOG.md) for details about version upgrades.
+
+## Tests
+
+To run the test suite, you first need to clone this repo and then install all
+dependencies [through Composer](https://getcomposer.org):
+
+```bash
+$ composer install
+```
+
+To run the test suite, go to the project root and run:
+
+```bash
+$ php vendor/bin/phpunit
+```
+
+The test suite contains a number of tests that rely on a working internet
+connection, alternatively you can also run it like this:
+
+```bash
+$ php vendor/bin/phpunit --exclude-group internet
+```

+## More
+
+* If you want to learn more about processing streams of data, refer to the
+  documentation of the underlying
+  [react/stream](https://github.com/reactphp/stream) component.
+* If you want to learn more about how the
+  [`ConnectorInterface`](#connectorinterface) and its usual implementations look
+  like, refer to the documentation of the underlying
+  [react/socket component](https://github.com/reactphp/socket).
+* As an alternative to a SOCKS (SOCKS4/SOCKS5) proxy, you may also want to look into
+  using an HTTP CONNECT proxy instead.
+  You may want to use [clue/http-proxy-react](https://github.com/clue/php-http-proxy-react)
+  which also provides an implementation of the
+  [`ConnectorInterface`](#connectorinterface) so that supporting either proxy
+  protocol should be fairly trivial.
+* If you're dealing with public proxies, you'll likely have to work with mixed
+  quality and unreliable proxies. You may want to look into using
+  [clue/connection-manager-extra](https://github.com/clue/php-connection-manager-extra)
+  which allows retrying unreliable ones, implying connection timeouts,
+  concurrently working with multiple connectors and more.
+* If you're looking for an end-user SOCKS server daemon, you may want to use
+  [LeProxy](https://leproxy.org/) or [clue/psocksd](https://github.com/clue/psocksd).

+## Synopsis
+
+```php
+use GetOptionKit\OptionCollection;
+use GetOptionKit\OptionParser;
+use GetOptionKit\OptionPrinter\ConsoleOptionPrinter;
+
+$specs = new OptionCollection;
+$specs->add('f|foo:', 'option requires a value.' )
+    ->isa('String');
+
+$specs->add('b|bar+', 'option with multiple value.' )
+    ->isa('Number');
+
+$specs->add('ip+', 'Ip constraint' )
+    ->isa('Ip');
+
+$specs->add('email+', 'Email address constraint' )
+    ->isa('Email');
+
+$specs->add('z|zoo?', 'option with optional value.' )
+    ->isa('Boolean');
+
+$specs->add('file:', 'option value should be a file.' )
+    ->isa('File');
+
+$specs->add('v|verbose', 'verbose message.' );
+$specs->add('d|debug', 'debug message.' );
+$specs->add('long', 'long option name only.' );
+$specs->add('s', 'short option name only.' );
+
+$printer = new ConsoleOptionPrinter();
+echo $printer->render($specs);
+
+$parser = new OptionParser($specs);
+
+echo "Enabled options: \n";
+try {
+    $result = $parser->parse( $argv );
+    foreach ($result->keys as $key => $spec) {
+        print_r($spec);
+    }
+
+    $opt = $result->keys['foo']; // return the option object.
+    $str = $result->keys['foo']->value; // return the option value
+    
+    print_r($opt);
+    var_dump($str);
+    
+} catch( Exception $e ) {
+    echo $e->getMessage();
+}
+```
+
+
+## Documentation
+
+See <https://github.com/c9s/GetOptionKit/wiki> for more details.
+
+### Option Value Type
+
+The option value type help you validate the input,
+the following list is the current supported types:
+
+- `string`
+- `number`
+- `boolean`
+- `file`
+- `date`
+- `url`
+- `email`
+- `ip`
+- `ipv4`
+- `ipv6`
+- `regex`
+
+And here is the related sample code:
+
+```php
+$opt->add( 'f|foo:' , 'with string type value' )
+    ->isa('string');
+
+$opt->add( 'b|bar+' , 'with number type value' )
+    ->isa('number');
+
+$opt->add( 'z|zoo?' , 'with boolean type value' )
+    ->isa('boolean');
+
+$opt->add( 'file:' , 'with file type value' )
+    ->isa('file');
+
+$opt->add( 'date:' , 'with date type value' )
+    ->isa('date');
+
+$opt->add( 'url:' , 'with url type value' )
+    ->isa('url');
+
+$opt->add( 'email:' , 'with email type value' )
+    ->isa('email');
+
+$opt->add( 'ip:' , 'with ip(v4/v6) type value' )
+    ->isa('ip');
+
+$opt->add( 'ipv4:' , 'with ipv4 type value' )
+    ->isa('ipv4');
+
+$opt->add( 'ipv6:' , 'with ipv6 type value' )
+    ->isa('ipv6');
+
+$specs->add('r|regex:', 'with custom regex type value')
+      ->isa('Regex', '/^([a-z]+)$/');
+```
+
+> Please note that currently only `string`, `number`, `boolean` types can be validated.
+
+### ContinuousOptionParser
+
+```php
+$specs = new OptionCollection;
+$spec_verbose = $specs->add('v|verbose');
+$spec_color = $specs->add('c|color');
+$spec_debug = $specs->add('d|debug');
+$spec_verbose->description = 'verbose flag';
+
+// ContinuousOptionParser
+$parser = new ContinuousOptionParser( $specs );
+$result = $parser->parse(explode(' ','program -v -d test -a -b -c subcommand -e -f -g subcommand2'));
+$result2 = $parser->continueParse();
+```
+
+### OptionPrinter
+
+GetOptionKit\OptionPrinter can print options for you:
+
+    * Available options:
+                  -f, --foo   option requires a value.
+                  -b, --bar   option with multiple value.
+                  -z, --zoo   option with optional value.
+              -v, --verbose   verbose message.
+                -d, --debug   debug message.
+                     --long   long option name only.
+                         -s   short option name only.
+
+
+## Command-line app with subcommands
+
+For application with subcommands is designed by following form:
+
+
+    [app name] [app opts] 
+                 [subcommand1] [subcommand-opts]
+                 [subcommand2] [subcommand-opts]
+                 [subcommand3] [subcommand-opts]
+                 [arguments]
+
+You can check the `tests/GetOptionKit/ContinuousOptionParserTest.php` unit test file:
+
+```php
+// subcommand stack
+$subcommands = array('subcommand1','subcommand2','subcommand3');
+
+// different command has its own options
+$subcommandSpecs = array(
+    'subcommand1' => $cmdspecs,
+    'subcommand2' => $cmdspecs,
+    'subcommand3' => $cmdspecs,
+);
+
+// for saved options
+$subcommandOptions = array();
+
+// command arguments
+$arguments = array();
+
+$argv = explode(' ','program -v -d -c subcommand1 -a -b -c subcommand2 -c subcommand3 arg1 arg2 arg3');
+
+// parse application options first
+$parser = new ContinuousOptionParser( $appspecs );
+$app_options = $parser->parse( $argv );
+while (! $parser->isEnd()) {
+    if (@$subcommands[0] && $parser->getCurrentArgument() == $subcommands[0]) {
+        $parser->advance();
+        $subcommand = array_shift( $subcommands );
+        $parser->setSpecs( $subcommandSpecs[$subcommand] );
+        $subcommandOptions[ $subcommand ] = $parser->continueParse();
+    } else {
+        $arguments[] = $parser->advance();
+    }
+}
+```
+
+## Todo
+
+* Option Spec group.
+* option valid value checking.
+* custom command mapping.
+
+## Command Line Utility Design Concept
+
+* main program name should be easy to type, easy to remember.
+* subcommand should be easy to type, easy to remember. length should be shorter than 7 characters.
+* options should always have long descriptive name
+* a program should be easy to check usage.
+
+## General command interface
+
+To list usage of all subcommands or the program itself:
+
+	$ prog help
+
+To list the subcommand usage
+
+	$ prog help subcommand subcommand2 subcommand3

+# Événement
+
+Événement is a very simple event dispatching library for PHP.
+
+It has the same design goals as [Silex](http://silex-project.org) and
+[Pimple](http://pimple-project.org), to empower the user while staying concise
+and simple.
+
+It is very strongly inspired by the EventEmitter API found in
+[node.js](http://nodejs.org).
+
+[![Build Status](https://secure.travis-ci.org/igorw/evenement.png?branch=master)](http://travis-ci.org/igorw/evenement)
+
+## Fetch
+
+The recommended way to install Événement is [through composer](http://getcomposer.org).
+
+Just create a composer.json file for your project:
+
+```JSON
+{
+    "require": {
+        "evenement/evenement": "^3.0 || ^2.0"
+    }
+}
+```
+
+**Note:** The `3.x` version of Événement requires PHP 7 and the `2.x` version requires PHP 5.4. If you are
+using PHP 5.3, please use the `1.x` version:
+
+```JSON
+{
+    "require": {
+        "evenement/evenement": "^1.0"
+    }
+}
+```
+
+And run these two commands to install it:
+
+    $ curl -s http://getcomposer.org/installer | php
+    $ php composer.phar install
+
+Now you can add the autoloader, and you will have access to the library:
+
+```php
+<?php
+require 'vendor/autoload.php';
+```
+
+## Usage
+
+### Creating an Emitter
+
+```php
+<?php
+$emitter = new Evenement\EventEmitter();
+```
+
+### Adding Listeners
+
+```php
+<?php
+$emitter->on('user.created', function (User $user) use ($logger) {
+    $logger->log(sprintf("User '%s' was created.", $user->getLogin()));
+});
+```
+
+### Emitting Events
+
+```php
+<?php
+$emitter->emit('user.created', [$user]);
+```
+

+# Introduction
+
+Événement is is French and means "event". The événement library aims to
+provide a simple way of subscribing to events and notifying those subscribers
+whenever an event occurs.
+
+The API that it exposes is almost a direct port of the EventEmitter API found
+in node.js. It also includes an "EventEmitter". There are some minor
+differences however.
+
+The EventEmitter is an implementation of the publish-subscribe pattern, which
+is a generalized version of the observer pattern. The observer pattern
+specifies an observable subject, which observers can register themselves to.
+Once something interesting happens, the subject notifies its observers.
+
+Pub/sub takes the same idea but encapsulates the observation logic inside a
+separate object which manages all of its subscribers or listeners. Subscribers
+are bound to an event name, and will only receive notifications of the events
+they subscribed to.
+
+**TLDR: What does evenement do, in short? It provides a mapping from event
+names to a list of listener functions and triggers each listener for a given
+event when it is emitted.**
+
+Why do we do this, you ask? To achieve decoupling.
+
+It allows you to design a system where the core will emit events, and modules
+are able to subscribe to these events. And respond to them.

+# API
+
+The API that événement exposes is defined by the
+`Evenement\EventEmitterInterface`. The interface is useful if you want to
+define an interface that extends the emitter and implicitly defines certain
+events to be emitted, or if you want to type hint an `EventEmitter` to be
+passed to a method without coupling to the specific implementation.
+
+## on($event, callable $listener)
+
+Allows you to subscribe to an event.
+
+Example:
+
+```php
+$emitter->on('user.created', function (User $user) use ($logger) {
+    $logger->log(sprintf("User '%s' was created.", $user->getLogin()));
+});
+```
+
+Since the listener can be any callable, you could also use an instance method
+instead of the anonymous function:
+
+```php
+$loggerSubscriber = new LoggerSubscriber($logger);
+$emitter->on('user.created', array($loggerSubscriber, 'onUserCreated'));
+```
+
+This has the benefit that listener does not even need to know that the emitter
+exists.
+
+You can also accept more than one parameter for the listener:
+
+```php
+$emitter->on('numbers_added', function ($result, $a, $b) {});
+```
+
+## once($event, callable $listener)
+
+Convenience method that adds a listener which is guaranteed to only be called
+once.
+
+Example:
+
+```php
+$conn->once('connected', function () use ($conn, $data) {
+    $conn->send($data);
+});
+```
+
+## emit($event, array $arguments = [])
+
+Emit an event, which will call all listeners.
+
+Example:
+
+```php
+$conn->emit('data', [$data]);
+```
+
+The second argument to emit is an array of listener arguments. This is how you
+specify more args:
+
+```php
+$result = $a + $b;
+$emitter->emit('numbers_added', [$result, $a, $b]);
+```
+
+## listeners($event)
+
+Allows you to inspect the listeners attached to an event. Particularly useful
+to check if there are any listeners at all.
+
+Example:
+
+```php
+$e = new \RuntimeException('Everything is broken!');
+if (0 === count($emitter->listeners('error'))) {
+    throw $e;
+}
+```
+
+## removeListener($event, callable $listener)
+
+Remove a specific listener for a specific event.
+
+## removeAllListeners($event = null)
+
+Remove all listeners for a specific event or all listeners all together. This
+is useful for long-running processes, where you want to remove listeners in
+order to allow them to get garbage collected.

+# Example: Plugin system
+
+In this example I will show you how to create a generic plugin system with
+événement where plugins can alter the behaviour of the app. The app is a blog.
+Boring, I know. By using the EventEmitter it will be easy to extend this blog
+with additional functionality without modifying the core system.
+
+The blog is quite basic. Users are able to create blog posts when they log in.
+The users are stored in a static config file, so there is no sign up process.
+Once logged in they get a "new post" link which gives them a form where they
+can create a new blog post with plain HTML. That will store the post in a
+document database. The index lists all blog post titles by date descending.
+Clicking on the post title will take you to the full post.
+
+## Plugin structure
+
+The goal of the plugin system is to allow features to be added to the blog
+without modifying any core files of the blog.
+
+The plugins are managed through a config file, `plugins.json`. This JSON file
+contains a JSON-encoded list of class-names for plugin classes. This allows
+you to enable and disable plugins in a central location. The initial
+`plugins.json` is just an empty array:
+```json
+[]
+```
+
+A plugin class must implement the `PluginInterface`:
+```php
+interface PluginInterface
+{
+    function attachEvents(EventEmitterInterface $emitter);
+}
+```
+
+The `attachEvents` method allows the plugin to attach any events to the
+emitter. For example:
+```php
+class FooPlugin implements PluginInterface
+{
+    public function attachEvents(EventEmitterInterface $emitter)
+    {
+        $emitter->on('foo', function () {
+            echo 'bar!';
+        });
+    }
+}
+```
+
+The blog system creates an emitter instance and loads the plugins:
+```php
+$emitter = new EventEmitter();
+
+$pluginClasses = json_decode(file_get_contents('plugins.json'), true);
+foreach ($pluginClasses as $pluginClass) {
+    $plugin = new $pluginClass();
+    $pluginClass->attachEvents($emitter);
+}
+```
+
+This is the base system. There are no plugins yet, and there are no events yet
+either. That's because I don't know which extension points will be needed. I
+will add them on demand.
+
+## Feature: Markdown
+
+Writing blog posts in HTML sucks! Wouldn't it be great if I could write them
+in a nice format such as markdown, and have that be converted to HTML for me?
+
+This feature will need two extension points. I need to be able to mark posts
+as markdown, and I need to be able to hook into the rendering of the post body
+and convert it from markdown to HTML. So the blog needs two new events:
+`post.create` and `post.render`.
+
+In the code that creates the post, I'll insert the `post.create` event:
+```php
+class PostEvent
+{
+    public $post;
+
+    public function __construct(array $post)
+    {
+        $this->post = $post;
+    }
+}
+
+$post = createPostFromRequest($_POST);
+
+$event = new PostEvent($post);
+$emitter->emit('post.create', [$event]);
+$post = $event->post;
+
+$db->save('post', $post);
+```
+
+This shows that you can wrap a value in an event object to make it mutable,
+allowing listeners to change it.
+
+The same thing for the `post.render` event:
+```php
+public function renderPostBody(array $post)
+{
+    $emitter = $this->emitter;
+
+    $event = new PostEvent($post);
+    $emitter->emit('post.render', [$event]);
+    $post = $event->post;
+
+    return $post['body'];
+}
+
+<h1><?= $post['title'] %></h1>
+<p><?= renderPostBody($post) %></p>
+```
+
+Ok, the events are in place. It's time to create the first plugin, woohoo! I
+will call this the `MarkdownPlugin`, so here's `plugins.json`:
+```json
+[
+    "MarkdownPlugin"
+]
+```
+
+The `MarkdownPlugin` class will be autoloaded, so I don't have to worry about
+including any files. I just have to worry about implementing the plugin class.
+The `markdown` function represents a markdown to HTML converter.
+```php
+class MarkdownPlugin implements PluginInterface
+{
+    public function attachEvents(EventEmitterInterface $emitter)
+    {
+        $emitter->on('post.create', function (PostEvent $event) {
+            $event->post['format'] = 'markdown';
+        });
+
+        $emitter->on('post.render', function (PostEvent $event) {
+            if (isset($event->post['format']) && 'markdown' === $event->post['format']) {
+                $event->post['body'] = markdown($event->post['body']);
+            }
+        });
+    }
+}
+```
+
+There you go, the blog now renders posts as markdown. But all of the previous
+posts before the addition of the markdown plugin are still rendered correctly
+as raw HTML.

+* Bug fix: Adding a Content-Length to PHP stream wrapper requests if not set.
+  https://github.com/guzzle/guzzle/pull/1189
+
+## 6.0.2 - 2015-07-04
+
+* Fixed a memory leak in the curl handlers in which references to callbacks
+  were not being removed by `curl_reset`.
+* Cookies are now extracted properly before redirects.
+* Cookies now allow more character ranges.
+* Decoded Content-Encoding responses are now modified to correctly reflect
+  their state if the encoding was automatically removed by a handler. This
+  means that the `Content-Encoding` header may be removed an the
+  `Content-Length` modified to reflect the message size after removing the
+  encoding.
+* Added a more explicit error message when trying to use `form_params` and
+  `multipart` in the same request.
+* Several fixes for HHVM support.
+* Functions are now conditionally required using an additional level of
+  indirection to help with global Composer installations.
+
+## 6.0.1 - 2015-05-27
+
+* Fixed a bug with serializing the `query` request option where the `&`
+  separator was missing.
+* Added a better error message for when `body` is provided as an array. Please
+  use `form_params` or `multipart` instead.
+* Various doc fixes.
+
+## 6.0.0 - 2015-05-26
+
+* See the UPGRADING.md document for more information.
+* Added `multipart` and `form_params` request options.
+* Added `synchronous` request option.
+* Added the `on_headers` request option.
+* Fixed `expect` handling.
+* No longer adding default middlewares in the client ctor. These need to be
+  present on the provided handler in order to work.
+* Requests are no longer initiated when sending async requests with the
+  CurlMultiHandler. This prevents unexpected recursion from requests completing
+  while ticking the cURL loop.
+* Removed the semantics of setting `default` to `true`. This is no longer
+  required now that the cURL loop is not ticked for async requests.
+* Added request and response logging middleware.
+* No longer allowing self signed certificates when using the StreamHandler.
+* Ensuring that `sink` is valid if saving to a file.
+* Request exceptions now include a "handler context" which provides handler
+  specific contextual information.
+* Added `GuzzleHttp\RequestOptions` to allow request options to be applied
+  using constants.
+* `$maxHandles` has been removed from CurlMultiHandler.
+* `MultipartPostBody` is now part of the `guzzlehttp/psr7` package.
+
+## 5.3.0 - 2015-05-19
+
+* Mock now supports `save_to`
+* Marked `AbstractRequestEvent::getTransaction()` as public.
+* Fixed a bug in which multiple headers using different casing would overwrite
+  previous headers in the associative array.
+* Added `Utils::getDefaultHandler()`
+* Marked `GuzzleHttp\Client::getDefaultUserAgent` as deprecated.
+* URL scheme is now always lowercased.
+
+## 6.0.0-beta.1
+
+* Requires PHP >= 5.5
+* Updated to use PSR-7
+  * Requires immutable messages, which basically means an event based system
+    owned by a request instance is no longer possible.
+  * Utilizing the [Guzzle PSR-7 package](https://github.com/guzzle/psr7).
+  * Removed the dependency on `guzzlehttp/streams`. These stream abstractions
+    are available in the `guzzlehttp/psr7` package under the `GuzzleHttp\Psr7`
+    namespace.
+* Added middleware and handler system
+  * Replaced the Guzzle event and subscriber system with a middleware system.
+  * No longer depends on RingPHP, but rather places the HTTP handlers directly
+    in Guzzle, operating on PSR-7 messages.
+  * Retry logic is now encapsulated in `GuzzleHttp\Middleware::retry`, which
+    means the `guzzlehttp/retry-subscriber` is now obsolete.
+  * Mocking responses is now handled using `GuzzleHttp\Handler\MockHandler`.
+* Asynchronous responses
+  * No longer supports the `future` request option to send an async request.
+    Instead, use one of the `*Async` methods of a client (e.g., `requestAsync`,
+    `getAsync`, etc.).
+  * Utilizing `GuzzleHttp\Promise` instead of React's promise library to avoid
+    recursion required by chaining and forwarding react promises. See
+    https://github.com/guzzle/promises
+  * Added `requestAsync` and `sendAsync` to send request asynchronously.
+  * Added magic methods for `getAsync()`, `postAsync()`, etc. to send requests
+    asynchronously.
+* Request options
+  * POST and form updates
+    * Added the `form_fields` and `form_files` request options.
+    * Removed the `GuzzleHttp\Post` namespace.
+    * The `body` request option no longer accepts an array for POST requests.
+  * The `exceptions` request option has been deprecated in favor of the
+    `http_errors` request options.
+  * The `save_to` request option has been deprecated in favor of `sink` request
+    option.
+* Clients no longer accept an array of URI template string and variables for
+  URI variables. You will need to expand URI templates before passing them
+  into a client constructor or request method.
+* Client methods `get()`, `post()`, `put()`, `patch()`, `options()`, etc. are
+  now magic methods that will send synchronous requests.
+* Replaced `Utils.php` with plain functions in `functions.php`.
+* Removed `GuzzleHttp\Collection`.
+* Removed `GuzzleHttp\BatchResults`. Batched pool results are now returned as
+  an array.
+* Removed `GuzzleHttp\Query`. Query string handling is now handled using an
+  associative array passed into the `query` request option. The query string
+  is serialized using PHP's `http_build_query`. If you need more control, you
+  can pass the query string in as a string.
+* `GuzzleHttp\QueryParser` has been replaced with the
+  `GuzzleHttp\Psr7\parse_query`.
+
+## 5.2.0 - 2015-01-27
+
+* Added `AppliesHeadersInterface` to make applying headers to a request based
+  on the body more generic and not specific to `PostBodyInterface`.
+* Reduced the number of stack frames needed to send requests.
+* Nested futures are now resolved in the client rather than the RequestFsm
+* Finishing state transitions is now handled in the RequestFsm rather than the
+  RingBridge.
+* Added a guard in the Pool class to not use recursion for request retries.
+
+## 5.1.0 - 2014-12-19
+
+* Pool class no longer uses recursion when a request is intercepted.
+* The size of a Pool can now be dynamically adjusted using a callback.
+  See https://github.com/guzzle/guzzle/pull/943.
+* Setting a request option to `null` when creating a request with a client will
+  ensure that the option is not set. This allows you to overwrite default
+  request options on a per-request basis.
+  See https://github.com/guzzle/guzzle/pull/937.
+* Added the ability to limit which protocols are allowed for redirects by
+  specifying a `protocols` array in the `allow_redirects` request option.
+* Nested futures due to retries are now resolved when waiting for synchronous
+  responses. See https://github.com/guzzle/guzzle/pull/947.
+* `"0"` is now an allowed URI path. See
+  https://github.com/guzzle/guzzle/pull/935.
+* `Query` no longer typehints on the `$query` argument in the constructor,
+  allowing for strings and arrays.
+* Exceptions thrown in the `end` event are now correctly wrapped with Guzzle
+  specific exceptions if necessary.
+
+## 5.0.3 - 2014-11-03
+
+This change updates query strings so that they are treated as un-encoded values
+by default where the value represents an un-encoded value to send over the
+wire. A Query object then encodes the value before sending over the wire. This
+means that even value query string values (e.g., ":") are url encoded. This
+makes the Query class match PHP's http_build_query function. However, if you
+want to send requests over the wire using valid query string characters that do
+not need to be encoded, then you can provide a string to Url::setQuery() and
+pass true as the second argument to specify that the query string is a raw
+string that should not be parsed or encoded (unless a call to getQuery() is
+subsequently made, forcing the query-string to be converted into a Query
+object).
+
+## 5.0.2 - 2014-10-30
+
+* Added a trailing `\r\n` to multipart/form-data payloads. See
+  https://github.com/guzzle/guzzle/pull/871
+* Added a `GuzzleHttp\Pool::send()` convenience method to match the docs.
+* Status codes are now returned as integers. See
+  https://github.com/guzzle/guzzle/issues/881
+* No longer overwriting an existing `application/x-www-form-urlencoded` header
+  when sending POST requests, allowing for customized headers. See
+  https://github.com/guzzle/guzzle/issues/877
+* Improved path URL serialization.
+
+  * No longer double percent-encoding characters in the path or query string if
+    they are already encoded.
+  * Now properly encoding the supplied path to a URL object, instead of only
+    encoding ' ' and '?'.
+  * Note: This has been changed in 5.0.3 to now encode query string values by
+    default unless the `rawString` argument is provided when setting the query
+    string on a URL: Now allowing many more characters to be present in the
+    query string without being percent encoded. See http://tools.ietf.org/html/rfc3986#appendix-A
+
+## 5.0.1 - 2014-10-16
+
+Bugfix release.
+
+* Fixed an issue where connection errors still returned response object in
+  error and end events event though the response is unusable. This has been
+  corrected so that a response is not returned in the `getResponse` method of
+  these events if the response did not complete. https://github.com/guzzle/guzzle/issues/867
+* Fixed an issue where transfer statistics were not being populated in the
+  RingBridge. https://github.com/guzzle/guzzle/issues/866
+
+## 5.0.0 - 2014-10-12
+
+Adding support for non-blocking responses and some minor API cleanup.
+
+### New Features
+
+* Added support for non-blocking responses based on `guzzlehttp/guzzle-ring`.
+* Added a public API for creating a default HTTP adapter.
+* Updated the redirect plugin to be non-blocking so that redirects are sent
+  concurrently. Other plugins like this can now be updated to be non-blocking.
+* Added a "progress" event so that you can get upload and download progress
+  events.
+* Added `GuzzleHttp\Pool` which implements FutureInterface and transfers
+  requests concurrently using a capped pool size as efficiently as possible.
+* Added `hasListeners()` to EmitterInterface.
+* Removed `GuzzleHttp\ClientInterface::sendAll` and marked
+  `GuzzleHttp\Client::sendAll` as deprecated (it's still there, just not the
+  recommended way).
+
+### Breaking changes
+
+The breaking changes in this release are relatively minor. The biggest thing to
+look out for is that request and response objects no longer implement fluent
+interfaces.
+
+* Removed the fluent interfaces (i.e., `return $this`) from requests,
+  responses, `GuzzleHttp\Collection`, `GuzzleHttp\Url`,
+  `GuzzleHttp\Query`, `GuzzleHttp\Post\PostBody`, and
+  `GuzzleHttp\Cookie\SetCookie`. This blog post provides a good outline of
+  why I did this: http://ocramius.github.io/blog/fluent-interfaces-are-evil/.
+  This also makes the Guzzle message interfaces compatible with the current
+  PSR-7 message proposal.
+* Removed "functions.php", so that Guzzle is truly PSR-4 compliant. Except
+  for the HTTP request functions from function.php, these functions are now
+  implemented in `GuzzleHttp\Utils` using camelCase. `GuzzleHttp\json_decode`
+  moved to `GuzzleHttp\Utils::jsonDecode`. `GuzzleHttp\get_path` moved to
+  `GuzzleHttp\Utils::getPath`. `GuzzleHttp\set_path` moved to
+  `GuzzleHttp\Utils::setPath`. `GuzzleHttp\batch` should now be
+  `GuzzleHttp\Pool::batch`, which returns an `objectStorage`. Using functions.php
+  caused problems for many users: they aren't PSR-4 compliant, require an
+  explicit include, and needed an if-guard to ensure that the functions are not
+  declared multiple times.
+* Rewrote adapter layer.
+    * Removing all classes from `GuzzleHttp\Adapter`, these are now
+      implemented as callables that are stored in `GuzzleHttp\Ring\Client`.
+    * Removed the concept of "parallel adapters". Sending requests serially or
+      concurrently is now handled using a single adapter.
+    * Moved `GuzzleHttp\Adapter\Transaction` to `GuzzleHttp\Transaction`. The
+      Transaction object now exposes the request, response, and client as public
+      properties. The getters and setters have been removed.
+* Removed the "headers" event. This event was only useful for changing the
+  body a response once the headers of the response were known. You can implement
+  a similar behavior in a number of ways. One example might be to use a
+  FnStream that has access to the transaction being sent. For example, when the
+  first byte is written, you could check if the response headers match your
+  expectations, and if so, change the actual stream body that is being
+  written to.
+* Removed the `asArray` parameter from
+  `GuzzleHttp\Message\MessageInterface::getHeader`. If you want to get a header
+  value as an array, then use the newly added `getHeaderAsArray()` method of
+  `MessageInterface`. This change makes the Guzzle interfaces compatible with
+  the PSR-7 interfaces.
+* `GuzzleHttp\Message\MessageFactory` no longer allows subclasses to add
+  custom request options using double-dispatch (this was an implementation
+  detail). Instead, you should now provide an associative array to the
+  constructor which is a mapping of the request option name mapping to a
+  function that applies the option value to a request.
+* Removed the concept of "throwImmediately" from exceptions and error events.
+  This control mechanism was used to stop a transfer of concurrent requests
+  from completing. This can now be handled by throwing the exception or by
+  cancelling a pool of requests or each outstanding future request individually.
+* Updated to "GuzzleHttp\Streams" 3.0.
+    * `GuzzleHttp\Stream\StreamInterface::getContents()` no longer accepts a
+      `maxLen` parameter. This update makes the Guzzle streams project
+      compatible with the current PSR-7 proposal.
+    * `GuzzleHttp\Stream\Stream::__construct`,
+      `GuzzleHttp\Stream\Stream::factory`, and
+      `GuzzleHttp\Stream\Utils::create` no longer accept a size in the second
+      argument. They now accept an associative array of options, including the
+      "size" key and "metadata" key which can be used to provide custom metadata.
+
+## 4.2.2 - 2014-09-08
+
+* Fixed a memory leak in the CurlAdapter when reusing cURL handles.
+* No longer using `request_fulluri` in stream adapter proxies.
+* Relative redirects are now based on the last response, not the first response.
+
+## 4.2.1 - 2014-08-19
+
+* Ensuring that the StreamAdapter does not always add a Content-Type header
+* Adding automated github releases with a phar and zip
+
+## 4.2.0 - 2014-08-17
+
+* Now merging in default options using a case-insensitive comparison.
+  Closes https://github.com/guzzle/guzzle/issues/767
+* Added the ability to automatically decode `Content-Encoding` response bodies
+  using the `decode_content` request option. This is set to `true` by default
+  to decode the response body if it comes over the wire with a
+  `Content-Encoding`. Set this value to `false` to disable decoding the
+  response content, and pass a string to provide a request `Accept-Encoding`
+  header and turn on automatic response decoding. This feature now allows you
+  to pass an `Accept-Encoding` header in the headers of a request but still
+  disable automatic response decoding.
+  Closes https://github.com/guzzle/guzzle/issues/764
+* Added the ability to throw an exception immediately when transferring
+  requests in parallel. Closes https://github.com/guzzle/guzzle/issues/760
+* Updating guzzlehttp/streams dependency to ~2.1
+* No longer utilizing the now deprecated namespaced methods from the stream
+  package.
+
+## 4.1.8 - 2014-08-14
+
+* Fixed an issue in the CurlFactory that caused setting the `stream=false`
+  request option to throw an exception.
+  See: https://github.com/guzzle/guzzle/issues/769
+* TransactionIterator now calls rewind on the inner iterator.
+  See: https://github.com/guzzle/guzzle/pull/765
+* You can now set the `Content-Type` header to `multipart/form-data`
+  when creating POST requests to force multipart bodies.
+  See https://github.com/guzzle/guzzle/issues/768
+
+## 4.1.7 - 2014-08-07
+
+* Fixed an error in the HistoryPlugin that caused the same request and response
+  to be logged multiple times when an HTTP protocol error occurs.
+* Ensuring that cURL does not add a default Content-Type when no Content-Type
+  has been supplied by the user. This prevents the adapter layer from modifying
+  the request that is sent over the wire after any listeners may have already
+  put the request in a desired state (e.g., signed the request).
+* Throwing an exception when you attempt to send requests that have the
+  "stream" set to true in parallel using the MultiAdapter.
+* Only calling curl_multi_select when there are active cURL handles. This was
+  previously changed and caused performance problems on some systems due to PHP
+  always selecting until the maximum select timeout.
+* Fixed a bug where multipart/form-data POST fields were not correctly
+  aggregated (e.g., values with "&").
+
+## 4.1.6 - 2014-08-03
+
+* Added helper methods to make it easier to represent messages as strings,
+  including getting the start line and getting headers as a string.
+
+## 4.1.5 - 2014-08-02
+
+* Automatically retrying cURL "Connection died, retrying a fresh connect"
+  errors when possible.
+* cURL implementation cleanup
+* Allowing multiple event subscriber listeners to be registered per event by
+  passing an array of arrays of listener configuration.
+
+## 4.1.4 - 2014-07-22
+
+* Fixed a bug that caused multi-part POST requests with more than one field to
+  serialize incorrectly.
+* Paths can now be set to "0"
+* `ResponseInterface::xml` now accepts a `libxml_options` option and added a
+  missing default argument that was required when parsing XML response bodies.
+* A `save_to` stream is now created lazily, which means that files are not
+  created on disk unless a request succeeds.
+
+## 4.1.3 - 2014-07-15
+
+* Various fixes to multipart/form-data POST uploads
+* Wrapping function.php in an if-statement to ensure Guzzle can be used
+  globally and in a Composer install
+* Fixed an issue with generating and merging in events to an event array
+* POST headers are only applied before sending a request to allow you to change
+  the query aggregator used before uploading
+* Added much more robust query string parsing
+* Fixed various parsing and normalization issues with URLs
+* Fixing an issue where multi-valued headers were not being utilized correctly
+  in the StreamAdapter
+
+## 4.1.2 - 2014-06-18
+
+* Added support for sending payloads with GET requests
+
+## 4.1.1 - 2014-06-08
+
+* Fixed an issue related to using custom message factory options in subclasses
+* Fixed an issue with nested form fields in a multi-part POST
+* Fixed an issue with using the `json` request option for POST requests
+* Added `ToArrayInterface` to `GuzzleHttp\Cookie\CookieJar`
+
+## 4.1.0 - 2014-05-27
+
+* Added a `json` request option to easily serialize JSON payloads.
+* Added a `GuzzleHttp\json_decode()` wrapper to safely parse JSON.
+* Added `setPort()` and `getPort()` to `GuzzleHttp\Message\RequestInterface`.
+* Added the ability to provide an emitter to a client in the client constructor.
+* Added the ability to persist a cookie session using $_SESSION.
+* Added a trait that can be used to add event listeners to an iterator.
+* Removed request method constants from RequestInterface.
+* Fixed warning when invalid request start-lines are received.
+* Updated MessageFactory to work with custom request option methods.
+* Updated cacert bundle to latest build.
+
+4.0.2 (2014-04-16)
+------------------
+
+* Proxy requests using the StreamAdapter now properly use request_fulluri (#632)
+* Added the ability to set scalars as POST fields (#628)
+
+## 4.0.1 - 2014-04-04
+
+* The HTTP status code of a response is now set as the exception code of
+  RequestException objects.
+* 303 redirects will now correctly switch from POST to GET requests.
+* The default parallel adapter of a client now correctly uses the MultiAdapter.
+* HasDataTrait now initializes the internal data array as an empty array so
+  that the toArray() method always returns an array.
+
+## 4.0.0 - 2014-03-29
+
+* For more information on the 4.0 transition, see:
+  http://mtdowling.com/blog/2014/03/15/guzzle-4-rc/
+* For information on changes and upgrading, see:
+  https://github.com/guzzle/guzzle/blob/master/UPGRADING.md#3x-to-40
+* Added `GuzzleHttp\batch()` as a convenience function for sending requests in
+  parallel without needing to write asynchronous code.
+* Restructured how events are added to `GuzzleHttp\ClientInterface::sendAll()`.
+  You can now pass a callable or an array of associative arrays where each
+  associative array contains the "fn", "priority", and "once" keys.
+
+## 4.0.0.rc-2 - 2014-03-25
+
+* Removed `getConfig()` and `setConfig()` from clients to avoid confusion
+  around whether things like base_url, message_factory, etc. should be able to
+  be retrieved or modified.
+* Added `getDefaultOption()` and `setDefaultOption()` to ClientInterface
+* functions.php functions were renamed using snake_case to match PHP idioms
+* Added support for `HTTP_PROXY`, `HTTPS_PROXY`, and
+  `GUZZLE_CURL_SELECT_TIMEOUT` environment variables
+* Added the ability to specify custom `sendAll()` event priorities
+* Added the ability to specify custom stream context options to the stream
+  adapter.
+* Added a functions.php function for `get_path()` and `set_path()`
+* CurlAdapter and MultiAdapter now use a callable to generate curl resources
+* MockAdapter now properly reads a body and emits a `headers` event
+* Updated Url class to check if a scheme and host are set before adding ":"
+  and "//". This allows empty Url (e.g., "") to be serialized as "".
+* Parsing invalid XML no longer emits warnings
+* Curl classes now properly throw AdapterExceptions
+* Various performance optimizations
+* Streams are created with the faster `Stream\create()` function
+* Marked deprecation_proxy() as internal
+* Test server is now a collection of static methods on a class
+
+## 4.0.0-rc.1 - 2014-03-15
+
+* See https://github.com/guzzle/guzzle/blob/master/UPGRADING.md#3x-to-40
+
+## 3.8.1 - 2014-01-28
+
+* Bug: Always using GET requests when redirecting from a 303 response
+* Bug: CURLOPT_SSL_VERIFYHOST is now correctly set to false when setting `$certificateAuthority` to false in
+  `Guzzle\Http\ClientInterface::setSslVerification()`
+* Bug: RedirectPlugin now uses strict RFC 3986 compliance when combining a base URL with a relative URL
+* Bug: The body of a request can now be set to `"0"`
+* Sending PHP stream requests no longer forces `HTTP/1.0`
+* Adding more information to ExceptionCollection exceptions so that users have more context, including a stack trace of
+  each sub-exception
+* Updated the `$ref` attribute in service descriptions to merge over any existing parameters of a schema (rather than
+  clobbering everything).
+* Merging URLs will now use the query string object from the relative URL (thus allowing custom query aggregators)
+* Query strings are now parsed in a way that they do no convert empty keys with no value to have a dangling `=`.
+  For example `foo&bar=baz` is now correctly parsed and recognized as `foo&bar=baz` rather than `foo=&bar=baz`.
+* Now properly escaping the regular expression delimiter when matching Cookie domains.
+* Network access is now disabled when loading XML documents
+
+## 3.8.0 - 2013-12-05
+
+* Added the ability to define a POST name for a file
+* JSON response parsing now properly walks additionalProperties
+* cURL error code 18 is now retried automatically in the BackoffPlugin
+* Fixed a cURL error when URLs contain fragments
+* Fixed an issue in the BackoffPlugin retry event where it was trying to access all exceptions as if they were
+  CurlExceptions
+* CURLOPT_PROGRESS function fix for PHP 5.5 (69fcc1e)

+## 3.7.0 - 2013-06-10
+
+* See UPGRADING.md for more information on how to upgrade.
+* Requests now support the ability to specify an array of $options when creating a request to more easily modify a
+  request. You can pass a 'request.options' configuration setting to a client to apply default request options to
+  every request created by a client (e.g. default query string variables, headers, curl options, etc.).
+* Added a static facade class that allows you to use Guzzle with static methods and mount the class to `\Guzzle`.
+  See `Guzzle\Http\StaticClient::mount`.
+* Added `command.request_options` to `Guzzle\Service\Command\AbstractCommand` to pass request options to requests
+      created by a command (e.g. custom headers, query string variables, timeout settings, etc.).
+* Stream size in `Guzzle\Stream\PhpStreamRequestFactory` will now be set if Content-Length is returned in the
+  headers of a response
+* Added `Guzzle\Common\Collection::setPath($path, $value)` to set a value into an array using a nested key
+  (e.g. `$collection->setPath('foo/baz/bar', 'test'); echo $collection['foo']['bar']['bar'];`)
+* ServiceBuilders now support storing and retrieving arbitrary data
+* CachePlugin can now purge all resources for a given URI
+* CachePlugin can automatically purge matching cached items when a non-idempotent request is sent to a resource

+* Fixing BC break: Added back the MonologLogAdapter implementation rather than extending from PsrLog so that older
+  Symfony users can still use the old version of Monolog.
+* Fixing BC break: Added the implementation back in for `Guzzle\Http\Message\AbstractMessage::getTokenizedHeader()`.
+  Now triggering an E_USER_DEPRECATED warning when used. Use `$message->getHeader()->parseParams()`.
+* Several performance improvements to `Guzzle\Common\Collection`
+* Added an `$options` argument to the end of the following methods of `Guzzle\Http\ClientInterface`:
+  createRequest, head, delete, put, patch, post, options, prepareRequest
+* Added an `$options` argument to the end of `Guzzle\Http\Message\Request\RequestFactoryInterface::createRequest()`
+* Added an `applyOptions()` method to `Guzzle\Http\Message\Request\RequestFactoryInterface`
+* Changed `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $body = null)` to
+  `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $options = array())`. You can still pass in a
+  resource, string, or EntityBody into the $options parameter to specify the download location of the response.
+* Changed `Guzzle\Common\Collection::__construct($data)` to no longer accepts a null value for `$data` but a
+  default `array()`
+* Added `Guzzle\Stream\StreamInterface::isRepeatable`
+* Removed `Guzzle\Http\ClientInterface::setDefaultHeaders(). Use
+  $client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`. or

+* CacheKeyProviderInterface and DefaultCacheKeyProvider are no longer used. All of this logic is handled in a
+  CacheStorageInterface. These two objects and interface will be removed in a future version.
+* Always setting X-cache headers on cached responses
+* Default cache TTLs are now handled by the CacheStorageInterface of a CachePlugin
+* `CacheStorageInterface::cache($key, Response $response, $ttl = null)` has changed to `cache(RequestInterface

+  CanCacheStrategyInterface $canCache = null)`
+* Added `RevalidationInterface::shouldRevalidate(RequestInterface $request, Response $response)`
+
+## 3.6.0 - 2013-05-29
+
+* ServiceDescription now implements ToArrayInterface
+* Added command.hidden_params to blacklist certain headers from being treated as additionalParameters
+* Guzzle can now correctly parse incomplete URLs
+* Mixed casing of headers are now forced to be a single consistent casing across all values for that header.
+* Messages internally use a HeaderCollection object to delegate handling case-insensitive header resolution
+* Removed the whole changedHeader() function system of messages because all header changes now go through addHeader().
+* Specific header implementations can be created for complex headers. When a message creates a header, it uses a
+  HeaderFactory which can map specific headers to specific header classes. There is now a Link header and
+  CacheControl header implementation.
+* Removed from interface: Guzzle\Http\ClientInterface::setUriTemplate
+* Removed from interface: Guzzle\Http\ClientInterface::setCurlMulti()
+* Removed Guzzle\Http\Message\Request::receivedRequestHeader() and implemented this functionality in
+  Guzzle\Http\Curl\RequestMediator
+* Removed the optional $asString parameter from MessageInterface::getHeader(). Just cast the header to a string.
+* Removed the optional $tryChunkedTransfer option from Guzzle\Http\Message\EntityEnclosingRequestInterface
+* Removed the $asObjects argument from Guzzle\Http\Message\MessageInterface::getHeaders()
+* Removed Guzzle\Parser\ParserRegister::get(). Use getParser()
+* Removed Guzzle\Parser\ParserRegister::set(). Use registerParser().
+* All response header helper functions return a string rather than mixing Header objects and strings inconsistently
+* Removed cURL blacklist support. This is no longer necessary now that Expect, Accept, etc. are managed by Guzzle
+  directly via interfaces
+* Removed the injecting of a request object onto a response object. The methods to get and set a request still exist
+  but are a no-op until removed.
+* Most classes that used to require a `Guzzle\Service\Command\CommandInterface` typehint now request a
+  `Guzzle\Service\Command\ArrayCommandInterface`.
+* Added `Guzzle\Http\Message\RequestInterface::startResponse()` to the RequestInterface to handle injecting a response
+  on a request while the request is still being transferred
+* The ability to case-insensitively search for header values
+* Guzzle\Http\Message\Header::hasExactHeader
+* Guzzle\Http\Message\Header::raw. Use getAll()
+* Deprecated cache control specific methods on Guzzle\Http\Message\AbstractMessage. Use the CacheControl header object
+  instead.
+* `Guzzle\Service\Command\CommandInterface` now extends from ToArrayInterface and ArrayAccess
+* Added the ability to cast Model objects to a string to view debug information.
+
+## 3.5.0 - 2013-05-13
+
+* Bug: Fixed a regression so that request responses are parsed only once per oncomplete event rather than multiple times
+* Bug: Better cleanup of one-time events across the board (when an event is meant to fire once, it will now remove
+  itself from the EventDispatcher)
+* Bug: `Guzzle\Log\MessageFormatter` now properly writes "total_time" and "connect_time" values
+* Bug: Cloning an EntityEnclosingRequest now clones the EntityBody too
+* Bug: Fixed an undefined index error when parsing nested JSON responses with a sentAs parameter that reference a
+  non-existent key
+* Bug: All __call() method arguments are now required (helps with mocking frameworks)
+* Deprecating Response::getRequest() and now using a shallow clone of a request object to remove a circular reference
+  to help with refcount based garbage collection of resources created by sending a request
+* Deprecating ZF1 cache and log adapters. These will be removed in the next major version.
+* Deprecating `Response::getPreviousResponse()` (method signature still exists, but it's deprecated). Use the
+  HistoryPlugin for a history.
+* Added a `responseBody` alias for the `response_body` location
+* Refactored internals to no longer rely on Response::getRequest()
+* HistoryPlugin can now be cast to a string
+* HistoryPlugin now logs transactions rather than requests and responses to more accurately keep track of the requests
+  and responses that are sent over the wire
+* Added `getEffectiveUrl()` and `getRedirectCount()` to Response objects
+
+## 3.4.3 - 2013-04-30
+

+* Configuration loading now allows remote files
+
+## 3.4.1 - 2013-04-16

+* Large refactoring to how CurlMulti handles work. There is now a proxy that sits in front of a pool of CurlMulti
+  handles. This greatly simplifies the implementation, fixes a couple bugs, and provides a small performance boost.
+* Exceptions are now properly grouped when sending requests in parallel
+* Redirects are now properly aggregated when a multi transaction fails
+* Redirects now set the response on the original object even in the event of a failure
+* Bug fix: Model names are now properly set even when using $refs

+* The new default CURLOPT_TIMEOUT setting has been increased to 150 seconds so that Guzzle works on poor connections.
+* Added a feature to EntityEnclosingRequest::setBody() that will automatically set the Content-Type of the request if
+  the Content-Type can be determined based on the entity body or the path of the request.
+* Added the ability to overwrite configuration settings in a client when grabbing a throwaway client from a builder.
+* Added support for a PSR-3 LogAdapter.
+* Added a `command.after_prepare` event

+* Added the ability to create a custom stream class when using a stream factory
+* Added a CachingEntityBody decorator
+* Added support for `additionalParameters` in service descriptions to define how custom parameters are serialized.
+* The bundled SSL certificate is now provided in the phar file and extracted when running Guzzle from a phar.
+* You can now send any EntityEnclosingRequest with POST fields or POST files and cURL will handle creating bodies
+* POST requests using a custom entity body are now treated exactly like PUT requests but with a custom cURL method. This
+  means that the redirect behavior of POST requests with custom bodies will not be the same as POST requests that use
+  POST fields or files (the latter is only used when emulating a form POST in the browser).
+* Lots of cleanup to CurlHandle::factory and RequestFactory::createRequest
+
+## 3.3.1 - 2013-03-10
+
+* Added the ability to create PHP streaming responses from HTTP requests
+* Bug fix: Running any filters when parsing response headers with service descriptions

+* BC: Setting a service description on a client will no longer modify the client's command factories.
+* BC: Emitting IO events from a RequestMediator is now a parameter that must be set in a request's curl options using
+  the 'emit_io' key. This was previously set under a request's parameters using 'curl.emit_io'

+  lowercase
+* Operation parameter objects are now lazy loaded internally
+* Added ErrorResponsePlugin that can throw errors for responses defined in service description operations' errorResponses
+* Added support for instantiating responseType=class responseClass classes. Classes must implement
+  `Guzzle\Service\Command\ResponseClassInterface`

+* CachePlugin
+    * Added support for stale-if-error so that the CachePlugin can now serve stale content from the cache on error
+    * Debug headers can now added to cached response in the CachePlugin
+
+## 3.2.0 - 2013-02-14
+
+* CurlMulti is no longer reused globally. A new multi object is created per-client. This helps to isolate clients.
+* URLs with no path no longer contain a "/" by default

+Guzzle, PHP HTTP client
+=======================
+
+[![Latest Version](https://img.shields.io/github/release/guzzle/guzzle.svg?style=flat-square)](https://github.com/guzzle/guzzle/releases)
+[![Build Status](https://img.shields.io/travis/guzzle/guzzle.svg?style=flat-square)](https://travis-ci.org/guzzle/guzzle)
+[![Total Downloads](https://img.shields.io/packagist/dt/guzzlehttp/guzzle.svg?style=flat-square)](https://packagist.org/packages/guzzlehttp/guzzle)
+
+Guzzle is a PHP HTTP client that makes it easy to send HTTP requests and
+trivial to integrate with web services.
+
+- Simple interface for building query strings, POST requests, streaming large
+  uploads, streaming large downloads, using HTTP cookies, uploading JSON data,
+  etc...
+- Can send both synchronous and asynchronous requests using the same interface.
+- Uses PSR-7 interfaces for requests, responses, and streams. This allows you
+  to utilize other PSR-7 compatible libraries with Guzzle.
+- Abstracts away the underlying HTTP transport, allowing you to write
+  environment and transport agnostic code; i.e., no hard dependency on cURL,
+  PHP streams, sockets, or non-blocking event loops.
+- Middleware system allows you to augment and compose client behavior.
+
+```php
+$client = new \GuzzleHttp\Client();
+$response = $client->request('GET', 'https://api.github.com/repos/guzzle/guzzle');
+
+echo $response->getStatusCode(); # 200
+echo $response->getHeaderLine('content-type'); # 'application/json; charset=utf8'
+echo $response->getBody(); # '{"id": 1420053, "name": "guzzle", ...}'
+
+# Send an asynchronous request.
+$request = new \GuzzleHttp\Psr7\Request('GET', 'http://httpbin.org');
+$promise = $client->sendAsync($request)->then(function ($response) {
+    echo 'I completed! ' . $response->getBody();
+});
+
+$promise->wait();
+```
+

+- [Stack Overflow](http://stackoverflow.com/questions/tagged/guzzle)
+- [Gitter](https://gitter.im/guzzle/guzzle)
+
+
+## Installing Guzzle
+
+The recommended way to install Guzzle is through
+[Composer](http://getcomposer.org).
+
+```bash
+# Install Composer
+curl -sS https://getcomposer.org/installer | php
+```
+
+Next, run the Composer command to install the latest stable version of Guzzle:
+
+```bash
+composer require guzzlehttp/guzzle
+```
+
+After installing, you need to require Composer's autoloader:
+
+```php
+require 'vendor/autoload.php';
+```
+
+You can then later update Guzzle using composer:
+
+ ```bash
+composer update
+ ```
+

+Guzzle Upgrade Guide
+====================
+
+5.0 to 6.0
+----------
+
+Guzzle now uses [PSR-7](http://www.php-fig.org/psr/psr-7/) for HTTP messages.
+Due to the fact that these messages are immutable, this prompted a refactoring
+of Guzzle to use a middleware based system rather than an event system. Any
+HTTP message interaction (e.g., `GuzzleHttp\Message\Request`) need to be
+updated to work with the new immutable PSR-7 request and response objects. Any
+event listeners or subscribers need to be updated to become middleware
+functions that wrap handlers (or are injected into a
+`GuzzleHttp\HandlerStack`).
+
+- Removed `GuzzleHttp\BatchResults`
+- Removed `GuzzleHttp\Collection`
+- Removed `GuzzleHttp\HasDataTrait`
+- Removed `GuzzleHttp\ToArrayInterface`
+- The `guzzlehttp/streams` dependency has been removed. Stream functionality
+  is now present in the `GuzzleHttp\Psr7` namespace provided by the
+  `guzzlehttp/psr7` package.
+- Guzzle no longer uses ReactPHP promises and now uses the
+  `guzzlehttp/promises` library. We use a custom promise library for three
+  significant reasons:
+  1. React promises (at the time of writing this) are recursive. Promise
+     chaining and promise resolution will eventually blow the stack. Guzzle
+     promises are not recursive as they use a sort of trampolining technique.
+     Note: there has been movement in the React project to modify promises to
+     no longer utilize recursion.
+  2. Guzzle needs to have the ability to synchronously block on a promise to
+     wait for a result. Guzzle promises allows this functionality (and does
+     not require the use of recursion).
+  3. Because we need to be able to wait on a result, doing so using React
+     promises requires wrapping react promises with RingPHP futures. This
+     overhead is no longer needed, reducing stack sizes, reducing complexity,
+     and improving performance.
+- `GuzzleHttp\Mimetypes` has been moved to a function in
+  `GuzzleHttp\Psr7\mimetype_from_extension` and
+  `GuzzleHttp\Psr7\mimetype_from_filename`.
+- `GuzzleHttp\Query` and `GuzzleHttp\QueryParser` have been removed. Query
+  strings must now be passed into request objects as strings, or provided to
+  the `query` request option when creating requests with clients. The `query`
+  option uses PHP's `http_build_query` to convert an array to a string. If you
+  need a different serialization technique, you will need to pass the query
+  string in as a string. There are a couple helper functions that will make
+  working with query strings easier: `GuzzleHttp\Psr7\parse_query` and
+  `GuzzleHttp\Psr7\build_query`.
+- Guzzle no longer has a dependency on RingPHP. Due to the use of a middleware
+  system based on PSR-7, using RingPHP and it's middleware system as well adds
+  more complexity than the benefits it provides. All HTTP handlers that were
+  present in RingPHP have been modified to work directly with PSR-7 messages
+  and placed in the `GuzzleHttp\Handler` namespace. This significantly reduces
+  complexity in Guzzle, removes a dependency, and improves performance. RingPHP
+  will be maintained for Guzzle 5 support, but will no longer be a part of
+  Guzzle 6.
+- As Guzzle now uses a middleware based systems the event system and RingPHP
+  integration has been removed. Note: while the event system has been removed,
+  it is possible to add your own type of event system that is powered by the
+  middleware system.
+  - Removed the `Event` namespace.
+  - Removed the `Subscriber` namespace.
+  - Removed `Transaction` class
+  - Removed `RequestFsm`
+  - Removed `RingBridge`
+  - `GuzzleHttp\Subscriber\Cookie` is now provided by
+    `GuzzleHttp\Middleware::cookies`
+  - `GuzzleHttp\Subscriber\HttpError` is now provided by
+    `GuzzleHttp\Middleware::httpError`
+  - `GuzzleHttp\Subscriber\History` is now provided by
+    `GuzzleHttp\Middleware::history`
+  - `GuzzleHttp\Subscriber\Mock` is now provided by
+    `GuzzleHttp\Handler\MockHandler`
+  - `GuzzleHttp\Subscriber\Prepare` is now provided by
+    `GuzzleHttp\PrepareBodyMiddleware`
+  - `GuzzleHttp\Subscriber\Redirect` is now provided by
+    `GuzzleHttp\RedirectMiddleware`
+- Guzzle now uses `Psr\Http\Message\UriInterface` (implements in
+  `GuzzleHttp\Psr7\Uri`) for URI support. `GuzzleHttp\Url` is now gone.
+- Static functions in `GuzzleHttp\Utils` have been moved to namespaced
+  functions under the `GuzzleHttp` namespace. This requires either a Composer
+  based autoloader or you to include functions.php.
+- `GuzzleHttp\ClientInterface::getDefaultOption` has been renamed to
+  `GuzzleHttp\ClientInterface::getConfig`.
+- `GuzzleHttp\ClientInterface::setDefaultOption` has been removed.
+- The `json` and `xml` methods of response objects has been removed. With the
+  migration to strictly adhering to PSR-7 as the interface for Guzzle messages,
+  adding methods to message interfaces would actually require Guzzle messages
+  to extend from PSR-7 messages rather then work with them directly.
+
+## Migrating to middleware
+
+The change to PSR-7 unfortunately required significant refactoring to Guzzle
+due to the fact that PSR-7 messages are immutable. Guzzle 5 relied on an event
+system from plugins. The event system relied on mutability of HTTP messages and
+side effects in order to work. With immutable messages, you have to change your
+workflow to become more about either returning a value (e.g., functional
+middlewares) or setting a value on an object. Guzzle v6 has chosen the
+functional middleware approach.
+
+Instead of using the event system to listen for things like the `before` event,
+you now create a stack based middleware function that intercepts a request on
+the way in and the promise of the response on the way out. This is a much
+simpler and more predictable approach than the event system and works nicely
+with PSR-7 middleware. Due to the use of promises, the middleware system is
+also asynchronous.
+
+v5:
+
+```php
+use GuzzleHttp\Event\BeforeEvent;
+$client = new GuzzleHttp\Client();
+// Get the emitter and listen to the before event.
+$client->getEmitter()->on('before', function (BeforeEvent $e) {
+    // Guzzle v5 events relied on mutation
+    $e->getRequest()->setHeader('X-Foo', 'Bar');
+});
+```
+
+v6:
+
+In v6, you can modify the request before it is sent using the `mapRequest`
+middleware. The idiomatic way in v6 to modify the request/response lifecycle is
+to setup a handler middleware stack up front and inject the handler into a
+client.
+
+```php
+use GuzzleHttp\Middleware;
+// Create a handler stack that has all of the default middlewares attached
+$handler = GuzzleHttp\HandlerStack::create();
+// Push the handler onto the handler stack
+$handler->push(Middleware::mapRequest(function (RequestInterface $request) {
+    // Notice that we have to return a request object
+    return $request->withHeader('X-Foo', 'Bar');
+}));
+// Inject the handler into the client
+$client = new GuzzleHttp\Client(['handler' => $handler]);
+```
+
+## POST Requests
+
+This version added the [`form_params`](http://guzzle.readthedocs.org/en/latest/request-options.html#form_params)
+and `multipart` request options. `form_params` is an associative array of
+strings or array of strings and is used to serialize an
+`application/x-www-form-urlencoded` POST request. The
+[`multipart`](http://guzzle.readthedocs.org/en/latest/request-options.html#multipart)
+option is now used to send a multipart/form-data POST request.
+
+`GuzzleHttp\Post\PostFile` has been removed. Use the `multipart` option to add
+POST files to a multipart/form-data request.
+
+The `body` option no longer accepts an array to send POST requests. Please use
+`multipart` or `form_params` instead.
+
+The `base_url` option has been renamed to `base_uri`.
+
+4.x to 5.0
+----------
+
+## Rewritten Adapter Layer
+
+Guzzle now uses [RingPHP](http://ringphp.readthedocs.org/en/latest) to send
+HTTP requests. The `adapter` option in a `GuzzleHttp\Client` constructor
+is still supported, but it has now been renamed to `handler`. Instead of
+passing a `GuzzleHttp\Adapter\AdapterInterface`, you must now pass a PHP
+`callable` that follows the RingPHP specification.
+
+## Removed Fluent Interfaces
+
+[Fluent interfaces were removed](http://ocramius.github.io/blog/fluent-interfaces-are-evil)
+from the following classes:
+
+- `GuzzleHttp\Collection`
+- `GuzzleHttp\Url`
+- `GuzzleHttp\Query`
+- `GuzzleHttp\Post\PostBody`
+- `GuzzleHttp\Cookie\SetCookie`
+
+## Removed functions.php
+
+Removed "functions.php", so that Guzzle is truly PSR-4 compliant. The following
+functions can be used as replacements.
+
+- `GuzzleHttp\json_decode` -> `GuzzleHttp\Utils::jsonDecode`
+- `GuzzleHttp\get_path` -> `GuzzleHttp\Utils::getPath`
+- `GuzzleHttp\Utils::setPath` -> `GuzzleHttp\set_path`
+- `GuzzleHttp\Pool::batch` -> `GuzzleHttp\batch`. This function is, however,
+  deprecated in favor of using `GuzzleHttp\Pool::batch()`.
+
+The "procedural" global client has been removed with no replacement (e.g.,
+`GuzzleHttp\get()`, `GuzzleHttp\post()`, etc.). Use a `GuzzleHttp\Client`
+object as a replacement.
+
+## `throwImmediately` has been removed
+
+The concept of "throwImmediately" has been removed from exceptions and error
+events. This control mechanism was used to stop a transfer of concurrent
+requests from completing. This can now be handled by throwing the exception or
+by cancelling a pool of requests or each outstanding future request
+individually.
+
+## headers event has been removed
+
+Removed the "headers" event. This event was only useful for changing the
+body a response once the headers of the response were known. You can implement
+a similar behavior in a number of ways. One example might be to use a
+FnStream that has access to the transaction being sent. For example, when the
+first byte is written, you could check if the response headers match your
+expectations, and if so, change the actual stream body that is being
+written to.
+
+## Updates to HTTP Messages
+
+Removed the `asArray` parameter from
+`GuzzleHttp\Message\MessageInterface::getHeader`. If you want to get a header
+value as an array, then use the newly added `getHeaderAsArray()` method of
+`MessageInterface`. This change makes the Guzzle interfaces compatible with
+the PSR-7 interfaces.
+
+3.x to 4.0
+----------
+
+## Overarching changes:
+
+- Now requires PHP 5.4 or greater.
+- No longer requires cURL to send requests.
+- Guzzle no longer wraps every exception it throws. Only exceptions that are
+  recoverable are now wrapped by Guzzle.
+- Various namespaces have been removed or renamed.
+- No longer requiring the Symfony EventDispatcher. A custom event dispatcher
+  based on the Symfony EventDispatcher is
+  now utilized in `GuzzleHttp\Event\EmitterInterface` (resulting in significant
+  speed and functionality improvements).
+
+Changes per Guzzle 3.x namespace are described below.
+
+## Batch
+
+The `Guzzle\Batch` namespace has been removed. This is best left to
+third-parties to implement on top of Guzzle's core HTTP library.
+
+## Cache
+
+The `Guzzle\Cache` namespace has been removed. (Todo: No suitable replacement
+has been implemented yet, but hoping to utilize a PSR cache interface).
+
+## Common
+
+- Removed all of the wrapped exceptions. It's better to use the standard PHP
+  library for unrecoverable exceptions.
+- `FromConfigInterface` has been removed.
+- `Guzzle\Common\Version` has been removed. The VERSION constant can be found
+  at `GuzzleHttp\ClientInterface::VERSION`.
+
+### Collection
+
+- `getAll` has been removed. Use `toArray` to convert a collection to an array.
+- `inject` has been removed.
+- `keySearch` has been removed.
+- `getPath` no longer supports wildcard expressions. Use something better like
+  JMESPath for this.
+- `setPath` now supports appending to an existing array via the `[]` notation.
+
+### Events
+
+Guzzle no longer requires Symfony's EventDispatcher component. Guzzle now uses
+`GuzzleHttp\Event\Emitter`.
+
+- `Symfony\Component\EventDispatcher\EventDispatcherInterface` is replaced by
+  `GuzzleHttp\Event\EmitterInterface`.
+- `Symfony\Component\EventDispatcher\EventDispatcher` is replaced by
+  `GuzzleHttp\Event\Emitter`.
+- `Symfony\Component\EventDispatcher\Event` is replaced by
+  `GuzzleHttp\Event\Event`, and Guzzle now has an EventInterface in
+  `GuzzleHttp\Event\EventInterface`.
+- `AbstractHasDispatcher` has moved to a trait, `HasEmitterTrait`, and
+  `HasDispatcherInterface` has moved to `HasEmitterInterface`. Retrieving the
+  event emitter of a request, client, etc. now uses the `getEmitter` method
+  rather than the `getDispatcher` method.
+
+#### Emitter
+
+- Use the `once()` method to add a listener that automatically removes itself
+  the first time it is invoked.
+- Use the `listeners()` method to retrieve a list of event listeners rather than
+  the `getListeners()` method.
+- Use `emit()` instead of `dispatch()` to emit an event from an emitter.
+- Use `attach()` instead of `addSubscriber()` and `detach()` instead of
+  `removeSubscriber()`.
+
+```php
+$mock = new Mock();
+// 3.x
+$request->getEventDispatcher()->addSubscriber($mock);
+$request->getEventDispatcher()->removeSubscriber($mock);
+// 4.x
+$request->getEmitter()->attach($mock);
+$request->getEmitter()->detach($mock);
+```
+
+Use the `on()` method to add a listener rather than the `addListener()` method.
+
+```php
+// 3.x
+$request->getEventDispatcher()->addListener('foo', function (Event $event) { /* ... */ } );
+// 4.x
+$request->getEmitter()->on('foo', function (Event $event, $name) { /* ... */ } );
+```
+
+## Http
+
+### General changes
+
+- The cacert.pem certificate has been moved to `src/cacert.pem`.
+- Added the concept of adapters that are used to transfer requests over the
+  wire.
+- Simplified the event system.
+- Sending requests in parallel is still possible, but batching is no longer a
+  concept of the HTTP layer. Instead, you must use the `complete` and `error`
+  events to asynchronously manage parallel request transfers.
+- `Guzzle\Http\Url` has moved to `GuzzleHttp\Url`.
+- `Guzzle\Http\QueryString` has moved to `GuzzleHttp\Query`.
+- QueryAggregators have been rewritten so that they are simply callable
+  functions.
+- `GuzzleHttp\StaticClient` has been removed. Use the functions provided in
+  `functions.php` for an easy to use static client instance.
+- Exceptions in `GuzzleHttp\Exception` have been updated to all extend from
+  `GuzzleHttp\Exception\TransferException`.
+
+### Client
+
+Calling methods like `get()`, `post()`, `head()`, etc. no longer create and
+return a request, but rather creates a request, sends the request, and returns
+the response.
+
+```php
+// 3.0
+$request = $client->get('/');
+$response = $request->send();
+
+// 4.0
+$response = $client->get('/');
+
+// or, to mirror the previous behavior
+$request = $client->createRequest('GET', '/');
+$response = $client->send($request);
+```
+
+`GuzzleHttp\ClientInterface` has changed.
+
+- The `send` method no longer accepts more than one request. Use `sendAll` to
+  send multiple requests in parallel.
+- `setUserAgent()` has been removed. Use a default request option instead. You
+  could, for example, do something like:
+  `$client->setConfig('defaults/headers/User-Agent', 'Foo/Bar ' . $client::getDefaultUserAgent())`.
+- `setSslVerification()` has been removed. Use default request options instead,
+  like `$client->setConfig('defaults/verify', true)`.
+
+`GuzzleHttp\Client` has changed.
+
+- The constructor now accepts only an associative array. You can include a
+  `base_url` string or array to use a URI template as the base URL of a client.
+  You can also specify a `defaults` key that is an associative array of default
+  request options. You can pass an `adapter` to use a custom adapter,
+  `batch_adapter` to use a custom adapter for sending requests in parallel, or
+  a `message_factory` to change the factory used to create HTTP requests and
+  responses.
+- The client no longer emits a `client.create_request` event.
+- Creating requests with a client no longer automatically utilize a URI
+  template. You must pass an array into a creational method (e.g.,
+  `createRequest`, `get`, `put`, etc.) in order to expand a URI template.
+
+### Messages
+
+Messages no longer have references to their counterparts (i.e., a request no
+longer has a reference to it's response, and a response no loger has a
+reference to its request). This association is now managed through a
+`GuzzleHttp\Adapter\TransactionInterface` object. You can get references to
+these transaction objects using request events that are emitted over the
+lifecycle of a request.
+
+#### Requests with a body
+
+- `GuzzleHttp\Message\EntityEnclosingRequest` and
+  `GuzzleHttp\Message\EntityEnclosingRequestInterface` have been removed. The
+  separation between requests that contain a body and requests that do not
+  contain a body has been removed, and now `GuzzleHttp\Message\RequestInterface`
+  handles both use cases.
+- Any method that previously accepts a `GuzzleHttp\Response` object now accept a
+  `GuzzleHttp\Message\ResponseInterface`.
+- `GuzzleHttp\Message\RequestFactoryInterface` has been renamed to
+  `GuzzleHttp\Message\MessageFactoryInterface`. This interface is used to create
+  both requests and responses and is implemented in
+  `GuzzleHttp\Message\MessageFactory`.
+- POST field and file methods have been removed from the request object. You
+  must now use the methods made available to `GuzzleHttp\Post\PostBodyInterface`
+  to control the format of a POST body. Requests that are created using a
+  standard `GuzzleHttp\Message\MessageFactoryInterface` will automatically use
+  a `GuzzleHttp\Post\PostBody` body if the body was passed as an array or if
+  the method is POST and no body is provided.
+
+```php
+$request = $client->createRequest('POST', '/');
+$request->getBody()->setField('foo', 'bar');
+$request->getBody()->addFile(new PostFile('file_key', fopen('/path/to/content', 'r')));
+```
+
+#### Headers
+
+- `GuzzleHttp\Message\Header` has been removed. Header values are now simply
+  represented by an array of values or as a string. Header values are returned
+  as a string by default when retrieving a header value from a message. You can
+  pass an optional argument of `true` to retrieve a header value as an array
+  of strings instead of a single concatenated string.
+- `GuzzleHttp\PostFile` and `GuzzleHttp\PostFileInterface` have been moved to
+  `GuzzleHttp\Post`. This interface has been simplified and now allows the
+  addition of arbitrary headers.
+- Custom headers like `GuzzleHttp\Message\Header\Link` have been removed. Most
+  of the custom headers are now handled separately in specific
+  subscribers/plugins, and `GuzzleHttp\Message\HeaderValues::parseParams()` has
+  been updated to properly handle headers that contain parameters (like the
+  `Link` header).
+
+#### Responses
+
+- `GuzzleHttp\Message\Response::getInfo()` and
+  `GuzzleHttp\Message\Response::setInfo()` have been removed. Use the event
+  system to retrieve this type of information.
+- `GuzzleHttp\Message\Response::getRawHeaders()` has been removed.
+- `GuzzleHttp\Message\Response::getMessage()` has been removed.
+- `GuzzleHttp\Message\Response::calculateAge()` and other cache specific
+  methods have moved to the CacheSubscriber.
+- Header specific helper functions like `getContentMd5()` have been removed.
+  Just use `getHeader('Content-MD5')` instead.
+- `GuzzleHttp\Message\Response::setRequest()` and
+  `GuzzleHttp\Message\Response::getRequest()` have been removed. Use the event
+  system to work with request and response objects as a transaction.
+- `GuzzleHttp\Message\Response::getRedirectCount()` has been removed. Use the
+  Redirect subscriber instead.
+- `GuzzleHttp\Message\Response::isSuccessful()` and other related methods have
+  been removed. Use `getStatusCode()` instead.
+
+#### Streaming responses
+
+Streaming requests can now be created by a client directly, returning a
+`GuzzleHttp\Message\ResponseInterface` object that contains a body stream
+referencing an open PHP HTTP stream.
+
+```php
+// 3.0
+use Guzzle\Stream\PhpStreamRequestFactory;
+$request = $client->get('/');
+$factory = new PhpStreamRequestFactory();
+$stream = $factory->fromRequest($request);
+$data = $stream->read(1024);
+
+// 4.0
+$response = $client->get('/', ['stream' => true]);
+// Read some data off of the stream in the response body
+$data = $response->getBody()->read(1024);
+```
+
+#### Redirects
+
+The `configureRedirects()` method has been removed in favor of a
+`allow_redirects` request option.
+
+```php
+// Standard redirects with a default of a max of 5 redirects
+$request = $client->createRequest('GET', '/', ['allow_redirects' => true]);
+
+// Strict redirects with a custom number of redirects
+$request = $client->createRequest('GET', '/', [
+    'allow_redirects' => ['max' => 5, 'strict' => true]
+]);
+```
+
+#### EntityBody
+
+EntityBody interfaces and classes have been removed or moved to
+`GuzzleHttp\Stream`. All classes and interfaces that once required
+`GuzzleHttp\EntityBodyInterface` now require
+`GuzzleHttp\Stream\StreamInterface`. Creating a new body for a request no
+longer uses `GuzzleHttp\EntityBody::factory` but now uses
+`GuzzleHttp\Stream\Stream::factory` or even better:
+`GuzzleHttp\Stream\create()`.
+
+- `Guzzle\Http\EntityBodyInterface` is now `GuzzleHttp\Stream\StreamInterface`
+- `Guzzle\Http\EntityBody` is now `GuzzleHttp\Stream\Stream`
+- `Guzzle\Http\CachingEntityBody` is now `GuzzleHttp\Stream\CachingStream`
+- `Guzzle\Http\ReadLimitEntityBody` is now `GuzzleHttp\Stream\LimitStream`
+- `Guzzle\Http\IoEmittyinEntityBody` has been removed.
+
+#### Request lifecycle events
+
+Requests previously submitted a large number of requests. The number of events
+emitted over the lifecycle of a request has been significantly reduced to make
+it easier to understand how to extend the behavior of a request. All events
+emitted during the lifecycle of a request now emit a custom
+`GuzzleHttp\Event\EventInterface` object that contains context providing
+methods and a way in which to modify the transaction at that specific point in
+time (e.g., intercept the request and set a response on the transaction).
+
+- `request.before_send` has been renamed to `before` and now emits a
+  `GuzzleHttp\Event\BeforeEvent`
+- `request.complete` has been renamed to `complete` and now emits a
+  `GuzzleHttp\Event\CompleteEvent`.
+- `request.sent` has been removed. Use `complete`.
+- `request.success` has been removed. Use `complete`.
+- `error` is now an event that emits a `GuzzleHttp\Event\ErrorEvent`.
+- `request.exception` has been removed. Use `error`.
+- `request.receive.status_line` has been removed.
+- `curl.callback.progress` has been removed. Use a custom `StreamInterface` to
+  maintain a status update.
+- `curl.callback.write` has been removed. Use a custom `StreamInterface` to
+  intercept writes.
+- `curl.callback.read` has been removed. Use a custom `StreamInterface` to
+  intercept reads.
+
+`headers` is a new event that is emitted after the response headers of a
+request have been received before the body of the response is downloaded. This
+event emits a `GuzzleHttp\Event\HeadersEvent`.
+
+You can intercept a request and inject a response using the `intercept()` event
+of a `GuzzleHttp\Event\BeforeEvent`, `GuzzleHttp\Event\CompleteEvent`, and
+`GuzzleHttp\Event\ErrorEvent` event.
+
+See: http://docs.guzzlephp.org/en/latest/events.html
+
+## Inflection
+
+The `Guzzle\Inflection` namespace has been removed. This is not a core concern
+of Guzzle.
+
+## Iterator
+
+The `Guzzle\Iterator` namespace has been removed.
+
+- `Guzzle\Iterator\AppendIterator`, `Guzzle\Iterator\ChunkedIterator`, and
+  `Guzzle\Iterator\MethodProxyIterator` are nice, but not a core requirement of
+  Guzzle itself.
+- `Guzzle\Iterator\FilterIterator` is no longer needed because an equivalent
+  class is shipped with PHP 5.4.
+- `Guzzle\Iterator\MapIterator` is not really needed when using PHP 5.5 because
+  it's easier to just wrap an iterator in a generator that maps values.
+
+For a replacement of these iterators, see https://github.com/nikic/iter
+
+## Log
+
+The LogPlugin has moved to https://github.com/guzzle/log-subscriber. The
+`Guzzle\Log` namespace has been removed. Guzzle now relies on
+`Psr\Log\LoggerInterface` for all logging. The MessageFormatter class has been
+moved to `GuzzleHttp\Subscriber\Log\Formatter`.
+
+## Parser
+
+The `Guzzle\Parser` namespace has been removed. This was previously used to
+make it possible to plug in custom parsers for cookies, messages, URI
+templates, and URLs; however, this level of complexity is not needed in Guzzle
+so it has been removed.
+
+- Cookie: Cookie parsing logic has been moved to
+  `GuzzleHttp\Cookie\SetCookie::fromString`.
+- Message: Message parsing logic for both requests and responses has been moved
+  to `GuzzleHttp\Message\MessageFactory::fromMessage`. Message parsing is only
+  used in debugging or deserializing messages, so it doesn't make sense for
+  Guzzle as a library to add this level of complexity to parsing messages.
+- UriTemplate: URI template parsing has been moved to
+  `GuzzleHttp\UriTemplate`. The Guzzle library will automatically use the PECL
+  URI template library if it is installed.
+- Url: URL parsing is now performed in `GuzzleHttp\Url::fromString` (previously
+  it was `Guzzle\Http\Url::factory()`). If custom URL parsing is necessary,
+  then developers are free to subclass `GuzzleHttp\Url`.
+
+## Plugin
+
+The `Guzzle\Plugin` namespace has been renamed to `GuzzleHttp\Subscriber`.
+Several plugins are shipping with the core Guzzle library under this namespace.
+
+- `GuzzleHttp\Subscriber\Cookie`: Replaces the old CookiePlugin. Cookie jar
+  code has moved to `GuzzleHttp\Cookie`.
+- `GuzzleHttp\Subscriber\History`: Replaces the old HistoryPlugin.
+- `GuzzleHttp\Subscriber\HttpError`: Throws errors when a bad HTTP response is
+  received.
+- `GuzzleHttp\Subscriber\Mock`: Replaces the old MockPlugin.
+- `GuzzleHttp\Subscriber\Prepare`: Prepares the body of a request just before
+  sending. This subscriber is attached to all requests by default.
+- `GuzzleHttp\Subscriber\Redirect`: Replaces the RedirectPlugin.
+
+The following plugins have been removed (third-parties are free to re-implement
+these if needed):
+
+- `GuzzleHttp\Plugin\Async` has been removed.
+- `GuzzleHttp\Plugin\CurlAuth` has been removed.
+- `GuzzleHttp\Plugin\ErrorResponse\ErrorResponsePlugin` has been removed. This
+  functionality should instead be implemented with event listeners that occur
+  after normal response parsing occurs in the guzzle/command package.
+
+The following plugins are not part of the core Guzzle package, but are provided
+in separate repositories:
+
+- `Guzzle\Http\Plugin\BackoffPlugin` has been rewritten to be much simpler
+  to build custom retry policies using simple functions rather than various
+  chained classes. See: https://github.com/guzzle/retry-subscriber
+- `Guzzle\Http\Plugin\Cache\CachePlugin` has moved to
+  https://github.com/guzzle/cache-subscriber
+- `Guzzle\Http\Plugin\Log\LogPlugin` has moved to
+  https://github.com/guzzle/log-subscriber
+- `Guzzle\Http\Plugin\Md5\Md5Plugin` has moved to
+  https://github.com/guzzle/message-integrity-subscriber
+- `Guzzle\Http\Plugin\Mock\MockPlugin` has moved to
+  `GuzzleHttp\Subscriber\MockSubscriber`.
+- `Guzzle\Http\Plugin\Oauth\OauthPlugin` has moved to
+  https://github.com/guzzle/oauth-subscriber
+
+## Service
+
+The service description layer of Guzzle has moved into two separate packages:
+
+- http://github.com/guzzle/command Provides a high level abstraction over web
+  services by representing web service operations using commands.
+- http://github.com/guzzle/guzzle-services Provides an implementation of
+  guzzle/command that provides request serialization and response parsing using
+  Guzzle service descriptions.
+
+## Stream
+
+Stream have moved to a separate package available at
+https://github.com/guzzle/streams.
+
+`Guzzle\Stream\StreamInterface` has been given a large update to cleanly take
+on the responsibilities of `Guzzle\Http\EntityBody` and
+`Guzzle\Http\EntityBodyInterface` now that they have been removed. The number
+of methods implemented by the `StreamInterface` has been drastically reduced to
+allow developers to more easily extend and decorate stream behavior.
+
+## Removed methods from StreamInterface
+
+- `getStream` and `setStream` have been removed to better encapsulate streams.
+- `getMetadata` and `setMetadata` have been removed in favor of
+  `GuzzleHttp\Stream\MetadataStreamInterface`.
+- `getWrapper`, `getWrapperData`, `getStreamType`, and `getUri` have all been
+  removed. This data is accessible when
+  using streams that implement `GuzzleHttp\Stream\MetadataStreamInterface`.
+- `rewind` has been removed. Use `seek(0)` for a similar behavior.
+
+## Renamed methods
+
+- `detachStream` has been renamed to `detach`.
+- `feof` has been renamed to `eof`.
+- `ftell` has been renamed to `tell`.
+- `readLine` has moved from an instance method to a static class method of
+  `GuzzleHttp\Stream\Stream`.
+
+## Metadata streams
+
+`GuzzleHttp\Stream\MetadataStreamInterface` has been added to denote streams
+that contain additional metadata accessible via `getMetadata()`.
+`GuzzleHttp\Stream\StreamInterface::getMetadata` and
+`GuzzleHttp\Stream\StreamInterface::setMetadata` have been removed.
+
+## StreamRequestFactory
+
+The entire concept of the StreamRequestFactory has been removed. The way this
+was used in Guzzle 3 broke the actual interface of sending streaming requests
+(instead of getting back a Response, you got a StreamInterface). Streaming
+PHP requests are now implemented through the `GuzzleHttp\Adapter\StreamAdapter`.
+
+3.6 to 3.7
+----------
+
+### Deprecations
+
+- You can now enable E_USER_DEPRECATED warnings to see if you are using any deprecated methods.:
+
+```php
+\Guzzle\Common\Version::$emitWarnings = true;
+```
+
+The following APIs and options have been marked as deprecated:
+
+- Marked `Guzzle\Http\Message\Request::isResponseBodyRepeatable()` as deprecated. Use `$request->getResponseBody()->isRepeatable()` instead.
+- Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
+- Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
+- Marked `Guzzle\Http\Message\Request::setIsRedirect()` as deprecated. Use the HistoryPlugin instead.
+- Marked `Guzzle\Http\Message\Request::isRedirect()` as deprecated. Use the HistoryPlugin instead.
+- Marked `Guzzle\Cache\CacheAdapterFactory::factory()` as deprecated
+- Marked `Guzzle\Service\Client::enableMagicMethods()` as deprecated. Magic methods can no longer be disabled on a Guzzle\Service\Client.
+- Marked `Guzzle\Parser\Url\UrlParser` as deprecated. Just use PHP's `parse_url()` and percent encode your UTF-8.
+- Marked `Guzzle\Common\Collection::inject()` as deprecated.
+- Marked `Guzzle\Plugin\CurlAuth\CurlAuthPlugin` as deprecated. Use
+  `$client->getConfig()->setPath('request.options/auth', array('user', 'pass', 'Basic|Digest|NTLM|Any'));` or
+  `$client->setDefaultOption('auth', array('user', 'pass', 'Basic|Digest|NTLM|Any'));`
+
+3.7 introduces `request.options` as a parameter for a client configuration and as an optional argument to all creational
+request methods. When paired with a client's configuration settings, these options allow you to specify default settings
+for various aspects of a request. Because these options make other previous configuration options redundant, several
+configuration options and methods of a client and AbstractCommand have been deprecated.
+
+- Marked `Guzzle\Service\Client::getDefaultHeaders()` as deprecated. Use `$client->getDefaultOption('headers')`.
+- Marked `Guzzle\Service\Client::setDefaultHeaders()` as deprecated. Use `$client->setDefaultOption('headers/{header_name}', 'value')`.
+- Marked 'request.params' for `Guzzle\Http\Client` as deprecated. Use `$client->setDefaultOption('params/{param_name}', 'value')`
+- Marked 'command.headers', 'command.response_body' and 'command.on_complete' as deprecated for AbstractCommand. These will work through Guzzle 4.0
+
+        $command = $client->getCommand('foo', array(
+            'command.headers' => array('Test' => '123'),
+            'command.response_body' => '/path/to/file'
+        ));
+
+        // Should be changed to:
+
+        $command = $client->getCommand('foo', array(
+            'command.request_options' => array(
+                'headers' => array('Test' => '123'),
+                'save_as' => '/path/to/file'
+            )
+        ));
+
+### Interface changes
+
+Additions and changes (you will need to update any implementations or subclasses you may have created):
+
+- Added an `$options` argument to the end of the following methods of `Guzzle\Http\ClientInterface`:
+  createRequest, head, delete, put, patch, post, options, prepareRequest
+- Added an `$options` argument to the end of `Guzzle\Http\Message\Request\RequestFactoryInterface::createRequest()`
+- Added an `applyOptions()` method to `Guzzle\Http\Message\Request\RequestFactoryInterface`
+- Changed `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $body = null)` to
+  `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $options = array())`. You can still pass in a
+  resource, string, or EntityBody into the $options parameter to specify the download location of the response.
+- Changed `Guzzle\Common\Collection::__construct($data)` to no longer accepts a null value for `$data` but a
+  default `array()`
+- Added `Guzzle\Stream\StreamInterface::isRepeatable`
+- Made `Guzzle\Http\Client::expandTemplate` and `getUriTemplate` protected methods.
+
+The following methods were removed from interfaces. All of these methods are still available in the concrete classes
+that implement them, but you should update your code to use alternative methods:
+
+- Removed `Guzzle\Http\ClientInterface::setDefaultHeaders(). Use
+  `$client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`. or
+  `$client->getConfig()->setPath('request.options/headers', array('header_name' => 'value'))` or
+  `$client->setDefaultOption('headers/{header_name}', 'value')`. or
+  `$client->setDefaultOption('headers', array('header_name' => 'value'))`.
+- Removed `Guzzle\Http\ClientInterface::getDefaultHeaders(). Use `$client->getConfig()->getPath('request.options/headers')`.
+- Removed `Guzzle\Http\ClientInterface::expandTemplate()`. This is an implementation detail.
+- Removed `Guzzle\Http\ClientInterface::setRequestFactory()`. This is an implementation detail.
+- Removed `Guzzle\Http\ClientInterface::getCurlMulti()`. This is a very specific implementation detail.
+- Removed `Guzzle\Http\Message\RequestInterface::canCache`. Use the CachePlugin.
+- Removed `Guzzle\Http\Message\RequestInterface::setIsRedirect`. Use the HistoryPlugin.
+- Removed `Guzzle\Http\Message\RequestInterface::isRedirect`. Use the HistoryPlugin.
+
+### Cache plugin breaking changes
+
+- CacheKeyProviderInterface and DefaultCacheKeyProvider are no longer used. All of this logic is handled in a
+  CacheStorageInterface. These two objects and interface will be removed in a future version.
+- Always setting X-cache headers on cached responses
+- Default cache TTLs are now handled by the CacheStorageInterface of a CachePlugin
+- `CacheStorageInterface::cache($key, Response $response, $ttl = null)` has changed to `cache(RequestInterface
+  $request, Response $response);`
+- `CacheStorageInterface::fetch($key)` has changed to `fetch(RequestInterface $request);`
+- `CacheStorageInterface::delete($key)` has changed to `delete(RequestInterface $request);`
+- Added `CacheStorageInterface::purge($url)`
+- `DefaultRevalidation::__construct(CacheKeyProviderInterface $cacheKey, CacheStorageInterface $cache, CachePlugin
+  $plugin)` has changed to `DefaultRevalidation::__construct(CacheStorageInterface $cache,
+  CanCacheStrategyInterface $canCache = null)`
+- Added `RevalidationInterface::shouldRevalidate(RequestInterface $request, Response $response)`
+
+3.5 to 3.6
+----------
+
+* Mixed casing of headers are now forced to be a single consistent casing across all values for that header.
+* Messages internally use a HeaderCollection object to delegate handling case-insensitive header resolution
+* Removed the whole changedHeader() function system of messages because all header changes now go through addHeader().
+  For example, setHeader() first removes the header using unset on a HeaderCollection and then calls addHeader().
+  Keeping the Host header and URL host in sync is now handled by overriding the addHeader method in Request.
+* Specific header implementations can be created for complex headers. When a message creates a header, it uses a
+  HeaderFactory which can map specific headers to specific header classes. There is now a Link header and
+  CacheControl header implementation.
+* Moved getLinks() from Response to just be used on a Link header object.
+
+If you previously relied on Guzzle\Http\Message\Header::raw(), then you will need to update your code to use the
+HeaderInterface (e.g. toArray(), getAll(), etc.).
+
+### Interface changes
+
+* Removed from interface: Guzzle\Http\ClientInterface::setUriTemplate
+* Removed from interface: Guzzle\Http\ClientInterface::setCurlMulti()
+* Removed Guzzle\Http\Message\Request::receivedRequestHeader() and implemented this functionality in
+  Guzzle\Http\Curl\RequestMediator
+* Removed the optional $asString parameter from MessageInterface::getHeader(). Just cast the header to a string.
+* Removed the optional $tryChunkedTransfer option from Guzzle\Http\Message\EntityEnclosingRequestInterface
+* Removed the $asObjects argument from Guzzle\Http\Message\MessageInterface::getHeaders()
+
+### Removed deprecated functions
+
+* Removed Guzzle\Parser\ParserRegister::get(). Use getParser()
+* Removed Guzzle\Parser\ParserRegister::set(). Use registerParser().
+
+### Deprecations
+
+* The ability to case-insensitively search for header values
+* Guzzle\Http\Message\Header::hasExactHeader
+* Guzzle\Http\Message\Header::raw. Use getAll()
+* Deprecated cache control specific methods on Guzzle\Http\Message\AbstractMessage. Use the CacheControl header object
+  instead.
+
+### Other changes
+
+* All response header helper functions return a string rather than mixing Header objects and strings inconsistently
+* Removed cURL blacklist support. This is no longer necessary now that Expect, Accept, etc. are managed by Guzzle
+  directly via interfaces
+* Removed the injecting of a request object onto a response object. The methods to get and set a request still exist
+  but are a no-op until removed.
+* Most classes that used to require a `Guzzle\Service\Command\CommandInterface` typehint now request a
+  `Guzzle\Service\Command\ArrayCommandInterface`.
+* Added `Guzzle\Http\Message\RequestInterface::startResponse()` to the RequestInterface to handle injecting a response
+  on a request while the request is still being transferred
+* `Guzzle\Service\Command\CommandInterface` now extends from ToArrayInterface and ArrayAccess
+
+3.3 to 3.4
+----------
+
+Base URLs of a client now follow the rules of http://tools.ietf.org/html/rfc3986#section-5.2.2 when merging URLs.
+
+3.2 to 3.3
+----------
+
+### Response::getEtag() quote stripping removed
+
+`Guzzle\Http\Message\Response::getEtag()` no longer strips quotes around the ETag response header
+
+### Removed `Guzzle\Http\Utils`
+
+The `Guzzle\Http\Utils` class was removed. This class was only used for testing.
+
+### Stream wrapper and type
+
+`Guzzle\Stream\Stream::getWrapper()` and `Guzzle\Stream\Stream::getStreamType()` are no longer converted to lowercase.
+
+### curl.emit_io became emit_io
+
+Emitting IO events from a RequestMediator is now a parameter that must be set in a request's curl options using the
+'emit_io' key. This was previously set under a request's parameters using 'curl.emit_io'
+
+3.1 to 3.2
+----------
+
+### CurlMulti is no longer reused globally
+
+Before 3.2, the same CurlMulti object was reused globally for each client. This can cause issue where plugins added
+to a single client can pollute requests dispatched from other clients.
+
+If you still wish to reuse the same CurlMulti object with each client, then you can add a listener to the
+ServiceBuilder's `service_builder.create_client` event to inject a custom CurlMulti object into each client as it is
+created.
+
+```php
+$multi = new Guzzle\Http\Curl\CurlMulti();
+$builder = Guzzle\Service\Builder\ServiceBuilder::factory('/path/to/config.json');
+$builder->addListener('service_builder.create_client', function ($event) use ($multi) {
+    $event['client']->setCurlMulti($multi);
+}
+});
+```
+
+### No default path
+
+URLs no longer have a default path value of '/' if no path was specified.
+
+Before:
+
+```php
+$request = $client->get('http://www.foo.com');
+echo $request->getUrl();
+// >> http://www.foo.com/
+```
+
+After:
+
+```php
+$request = $client->get('http://www.foo.com');
+echo $request->getUrl();
+// >> http://www.foo.com
+```
+
+### Less verbose BadResponseException
+
+The exception message for `Guzzle\Http\Exception\BadResponseException` no longer contains the full HTTP request and
+response information. You can, however, get access to the request and response object by calling `getRequest()` or
+`getResponse()` on the exception object.
+
+### Query parameter aggregation
+
+Multi-valued query parameters are no longer aggregated using a callback function. `Guzzle\Http\Query` now has a
+setAggregator() method that accepts a `Guzzle\Http\QueryAggregator\QueryAggregatorInterface` object. This object is
+responsible for handling the aggregation of multi-valued query string variables into a flattened hash.
+
+2.8 to 3.x
+----------
+
+### Guzzle\Service\Inspector
+
+Change `\Guzzle\Service\Inspector::fromConfig` to `\Guzzle\Common\Collection::fromConfig`
+
+**Before**
+
+```php
+use Guzzle\Service\Inspector;
+
+class YourClient extends \Guzzle\Service\Client
+{
+    public static function factory($config = array())
+    {
+        $default = array();
+        $required = array('base_url', 'username', 'api_key');
+        $config = Inspector::fromConfig($config, $default, $required);
+
+        $client = new self(
+            $config->get('base_url'),
+            $config->get('username'),
+            $config->get('api_key')
+        );
+        $client->setConfig($config);
+
+        $client->setDescription(ServiceDescription::factory(__DIR__ . DIRECTORY_SEPARATOR . 'client.json'));
+
+        return $client;
+    }
+```
+
+**After**
+
+```php
+use Guzzle\Common\Collection;
+
+class YourClient extends \Guzzle\Service\Client
+{
+    public static function factory($config = array())
+    {
+        $default = array();
+        $required = array('base_url', 'username', 'api_key');
+        $config = Collection::fromConfig($config, $default, $required);
+
+        $client = new self(
+            $config->get('base_url'),
+            $config->get('username'),
+            $config->get('api_key')
+        );
+        $client->setConfig($config);
+
+        $client->setDescription(ServiceDescription::factory(__DIR__ . DIRECTORY_SEPARATOR . 'client.json'));
+
+        return $client;
+    }
+```
+

+
+### Guzzle\Service\Description\ServiceDescription
+
+Commands are now called Operations
+
+**Before**
+
+```php
+use Guzzle\Service\Description\ServiceDescription;
+
+$sd = new ServiceDescription();
+$sd->getCommands();     // @returns ApiCommandInterface[]
+$sd->hasCommand($name);
+$sd->getCommand($name); // @returns ApiCommandInterface|null
+$sd->addCommand($command); // @param ApiCommandInterface $command
+```
+
+**After**
+
+```php
+use Guzzle\Service\Description\ServiceDescription;
+
+$sd = new ServiceDescription();
+$sd->getOperations();           // @returns OperationInterface[]
+$sd->hasOperation($name);
+$sd->getOperation($name);       // @returns OperationInterface|null
+$sd->addOperation($operation);  // @param OperationInterface $operation
+```
+
+### Guzzle\Common\Inflection\Inflector
+
+Namespace is now `Guzzle\Inflection\Inflector`
+
+### Guzzle\Http\Plugin
+
+Namespace is now `Guzzle\Plugin`. Many other changes occur within this namespace and are detailed in their own sections below.
+
+### Guzzle\Http\Plugin\LogPlugin and Guzzle\Common\Log
+
+Now `Guzzle\Plugin\Log\LogPlugin` and `Guzzle\Log` respectively.
+
+**Before**
+
+```php
+use Guzzle\Common\Log\ClosureLogAdapter;
+use Guzzle\Http\Plugin\LogPlugin;
+
+/** @var \Guzzle\Http\Client */
+$client;
+
+// $verbosity is an integer indicating desired message verbosity level
+$client->addSubscriber(new LogPlugin(new ClosureLogAdapter(function($m) { echo $m; }, $verbosity = LogPlugin::LOG_VERBOSE);
+```
+
+**After**
+
+```php
+use Guzzle\Log\ClosureLogAdapter;
+use Guzzle\Log\MessageFormatter;
+use Guzzle\Plugin\Log\LogPlugin;
+
+/** @var \Guzzle\Http\Client */
+$client;
+
+// $format is a string indicating desired message format -- @see MessageFormatter
+$client->addSubscriber(new LogPlugin(new ClosureLogAdapter(function($m) { echo $m; }, $format = MessageFormatter::DEBUG_FORMAT);
+```
+
+### Guzzle\Http\Plugin\CurlAuthPlugin
+
+Now `Guzzle\Plugin\CurlAuth\CurlAuthPlugin`.
+
+### Guzzle\Http\Plugin\ExponentialBackoffPlugin
+
+Now `Guzzle\Plugin\Backoff\BackoffPlugin`, and other changes.
+
+**Before**
+
+```php
+use Guzzle\Http\Plugin\ExponentialBackoffPlugin;
+
+$backoffPlugin = new ExponentialBackoffPlugin($maxRetries, array_merge(
+        ExponentialBackoffPlugin::getDefaultFailureCodes(), array(429)
+    ));
+
+$client->addSubscriber($backoffPlugin);
+```
+
+**After**
+
+```php
+use Guzzle\Plugin\Backoff\BackoffPlugin;
+use Guzzle\Plugin\Backoff\HttpBackoffStrategy;
+
+// Use convenient factory method instead -- see implementation for ideas of what
+// you can do with chaining backoff strategies
+$backoffPlugin = BackoffPlugin::getExponentialBackoff($maxRetries, array_merge(
+        HttpBackoffStrategy::getDefaultFailureCodes(), array(429)
+    ));
+$client->addSubscriber($backoffPlugin);
+```
+
+### Known Issues
+
+#### [BUG] Accept-Encoding header behavior changed unintentionally.
+
+(See #217) (Fixed in 09daeb8c666fb44499a0646d655a8ae36456575e)
+
+In version 2.8 setting the `Accept-Encoding` header would set the CURLOPT_ENCODING option, which permitted cURL to
+properly handle gzip/deflate compressed responses from the server. In versions affected by this bug this does not happen.
+See issue #217 for a workaround, or use a version containing the fix.

+# Features
+
+- [Promises/A+](https://promisesaplus.com/) implementation.
+- Promise resolution and chaining is handled iteratively, allowing for
+  "infinite" promise chaining.
+- Promises have a synchronous `wait` method.
+- Promises can be cancelled.
+- Works with any object that has a `then` function.
+- C# style async/await coroutine promises using
+  `GuzzleHttp\Promise\coroutine()`.
+
+
+# Quick start
+
+A *promise* represents the eventual result of an asynchronous operation. The
+primary way of interacting with a promise is through its `then` method, which
+registers callbacks to receive either a promise's eventual value or the reason
+why the promise cannot be fulfilled.
+
+
+## Callbacks
+
+Callbacks are registered with the `then` method by providing an optional 
+`$onFulfilled` followed by an optional `$onRejected` function.
+
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise->then(
+    // $onFulfilled
+    function ($value) {
+        echo 'The promise was fulfilled.';
+    },
+    // $onRejected
+    function ($reason) {
+        echo 'The promise was rejected.';
+    }
+);
+```
+
+*Resolving* a promise means that you either fulfill a promise with a *value* or
+reject a promise with a *reason*. Resolving a promises triggers callbacks
+registered with the promises's `then` method. These callbacks are triggered
+only once and in the order in which they were added.
+
+
+## Resolving a promise
+
+Promises are fulfilled using the `resolve($value)` method. Resolving a promise
+with any value other than a `GuzzleHttp\Promise\RejectedPromise` will trigger
+all of the onFulfilled callbacks (resolving a promise with a rejected promise
+will reject the promise and trigger the `$onRejected` callbacks).
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise
+    ->then(function ($value) {
+        // Return a value and don't break the chain
+        return "Hello, " . $value;
+    })
+    // This then is executed after the first then and receives the value
+    // returned from the first then.
+    ->then(function ($value) {
+        echo $value;
+    });
+
+// Resolving the promise triggers the $onFulfilled callbacks and outputs
+// "Hello, reader".
+$promise->resolve('reader.');
+```
+
+
+## Promise forwarding
+
+Promises can be chained one after the other. Each then in the chain is a new
+promise. The return value of a promise is what's forwarded to the next
+promise in the chain. Returning a promise in a `then` callback will cause the
+subsequent promises in the chain to only be fulfilled when the returned promise
+has been fulfilled. The next promise in the chain will be invoked with the
+resolved value of the promise.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$nextPromise = new Promise();
+
+$promise
+    ->then(function ($value) use ($nextPromise) {
+        echo $value;
+        return $nextPromise;
+    })
+    ->then(function ($value) {
+        echo $value;
+    });
+
+// Triggers the first callback and outputs "A"
+$promise->resolve('A');
+// Triggers the second callback and outputs "B"
+$nextPromise->resolve('B');
+```
+
+## Promise rejection
+
+When a promise is rejected, the `$onRejected` callbacks are invoked with the
+rejection reason.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise->then(null, function ($reason) {
+    echo $reason;
+});
+
+$promise->reject('Error!');
+// Outputs "Error!"
+```
+
+## Rejection forwarding
+
+If an exception is thrown in an `$onRejected` callback, subsequent
+`$onRejected` callbacks are invoked with the thrown exception as the reason.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise->then(null, function ($reason) {
+    throw new \Exception($reason);
+})->then(null, function ($reason) {
+    assert($reason->getMessage() === 'Error!');
+});
+
+$promise->reject('Error!');
+```
+
+You can also forward a rejection down the promise chain by returning a
+`GuzzleHttp\Promise\RejectedPromise` in either an `$onFulfilled` or
+`$onRejected` callback.
+
+```php
+use GuzzleHttp\Promise\Promise;
+use GuzzleHttp\Promise\RejectedPromise;
+
+$promise = new Promise();
+$promise->then(null, function ($reason) {
+    return new RejectedPromise($reason);
+})->then(null, function ($reason) {
+    assert($reason === 'Error!');
+});
+
+$promise->reject('Error!');
+```
+
+If an exception is not thrown in a `$onRejected` callback and the callback
+does not return a rejected promise, downstream `$onFulfilled` callbacks are
+invoked using the value returned from the `$onRejected` callback.
+
+```php
+use GuzzleHttp\Promise\Promise;
+use GuzzleHttp\Promise\RejectedPromise;
+
+$promise = new Promise();
+$promise
+    ->then(null, function ($reason) {
+        return "It's ok";
+    })
+    ->then(function ($value) {
+        assert($value === "It's ok");
+    });
+
+$promise->reject('Error!');
+```
+
+# Synchronous wait
+
+You can synchronously force promises to complete using a promise's `wait`
+method. When creating a promise, you can provide a wait function that is used
+to synchronously force a promise to complete. When a wait function is invoked
+it is expected to deliver a value to the promise or reject the promise. If the
+wait function does not deliver a value, then an exception is thrown. The wait
+function provided to a promise constructor is invoked when the `wait` function
+of the promise is called.
+
+```php
+$promise = new Promise(function () use (&$promise) {
+    $promise->resolve('foo');
+});
+
+// Calling wait will return the value of the promise.
+echo $promise->wait(); // outputs "foo"
+```
+
+If an exception is encountered while invoking the wait function of a promise,
+the promise is rejected with the exception and the exception is thrown.
+
+```php
+$promise = new Promise(function () use (&$promise) {
+    throw new \Exception('foo');
+});
+
+$promise->wait(); // throws the exception.
+```
+
+Calling `wait` on a promise that has been fulfilled will not trigger the wait
+function. It will simply return the previously resolved value.
+
+```php
+$promise = new Promise(function () { die('this is not called!'); });
+$promise->resolve('foo');
+echo $promise->wait(); // outputs "foo"
+```
+
+Calling `wait` on a promise that has been rejected will throw an exception. If
+the rejection reason is an instance of `\Exception` the reason is thrown.
+Otherwise, a `GuzzleHttp\Promise\RejectionException` is thrown and the reason
+can be obtained by calling the `getReason` method of the exception.
+
+```php
+$promise = new Promise();
+$promise->reject('foo');
+$promise->wait();
+```
+
+> PHP Fatal error:  Uncaught exception 'GuzzleHttp\Promise\RejectionException' with message 'The promise was rejected with value: foo'
+
+
+## Unwrapping a promise
+
+When synchronously waiting on a promise, you are joining the state of the
+promise into the current state of execution (i.e., return the value of the
+promise if it was fulfilled or throw an exception if it was rejected). This is
+called "unwrapping" the promise. Waiting on a promise will by default unwrap
+the promise state.
+
+You can force a promise to resolve and *not* unwrap the state of the promise
+by passing `false` to the first argument of the `wait` function:
+
+```php
+$promise = new Promise();
+$promise->reject('foo');
+// This will not throw an exception. It simply ensures the promise has
+// been resolved.
+$promise->wait(false);
+```
+
+When unwrapping a promise, the resolved value of the promise will be waited
+upon until the unwrapped value is not a promise. This means that if you resolve
+promise A with a promise B and unwrap promise A, the value returned by the
+wait function will be the value delivered to promise B.
+
+**Note**: when you do not unwrap the promise, no value is returned.
+
+
+# Cancellation
+
+You can cancel a promise that has not yet been fulfilled using the `cancel()`
+method of a promise. When creating a promise you can provide an optional
+cancel function that when invoked cancels the action of computing a resolution
+of the promise.
+
+
+# API
+
+
+## Promise
+
+When creating a promise object, you can provide an optional `$waitFn` and
+`$cancelFn`. `$waitFn` is a function that is invoked with no arguments and is
+expected to resolve the promise. `$cancelFn` is a function with no arguments
+that is expected to cancel the computation of a promise. It is invoked when the
+`cancel()` method of a promise is called.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise(
+    function () use (&$promise) {
+        $promise->resolve('waited');
+    },
+    function () {
+        // do something that will cancel the promise computation (e.g., close
+        // a socket, cancel a database query, etc...)
+    }
+);
+
+assert('waited' === $promise->wait());
+```
+
+A promise has the following methods:
+
+- `then(callable $onFulfilled, callable $onRejected) : PromiseInterface`
+  
+  Appends fulfillment and rejection handlers to the promise, and returns a new promise resolving to the return value of the called handler.
+
+- `otherwise(callable $onRejected) : PromiseInterface`
+  
+  Appends a rejection handler callback to the promise, and returns a new promise resolving to the return value of the callback if it is called, or to its original fulfillment value if the promise is instead fulfilled.
+
+- `wait($unwrap = true) : mixed`
+
+  Synchronously waits on the promise to complete.
+  
+  `$unwrap` controls whether or not the value of the promise is returned for a
+  fulfilled promise or if an exception is thrown if the promise is rejected.
+  This is set to `true` by default.
+
+- `cancel()`
+
+  Attempts to cancel the promise if possible. The promise being cancelled and
+  the parent most ancestor that has not yet been resolved will also be
+  cancelled. Any promises waiting on the cancelled promise to resolve will also
+  be cancelled.
+
+- `getState() : string`
+
+  Returns the state of the promise. One of `pending`, `fulfilled`, or
+  `rejected`.
+
+- `resolve($value)`
+
+  Fulfills the promise with the given `$value`.
+
+- `reject($reason)`
+
+  Rejects the promise with the given `$reason`.
+
+
+## FulfilledPromise
+
+A fulfilled promise can be created to represent a promise that has been
+fulfilled.
+
+```php
+use GuzzleHttp\Promise\FulfilledPromise;
+
+$promise = new FulfilledPromise('value');
+
+// Fulfilled callbacks are immediately invoked.
+$promise->then(function ($value) {
+    echo $value;
+});
+```
+
+
+## RejectedPromise
+
+A rejected promise can be created to represent a promise that has been
+rejected.
+
+```php
+use GuzzleHttp\Promise\RejectedPromise;
+
+$promise = new RejectedPromise('Error');
+
+// Rejected callbacks are immediately invoked.
+$promise->then(null, function ($reason) {
+    echo $reason;
+});
+```
+
+
+# Promise interop
+
+This library works with foreign promises that have a `then` method. This means
+you can use Guzzle promises with [React promises](https://github.com/reactphp/promise)
+for example. When a foreign promise is returned inside of a then method
+callback, promise resolution will occur recursively.
+
+```php
+// Create a React promise
+$deferred = new React\Promise\Deferred();
+$reactPromise = $deferred->promise();
+
+// Create a Guzzle promise that is fulfilled with a React promise.
+$guzzlePromise = new \GuzzleHttp\Promise\Promise();
+$guzzlePromise->then(function ($value) use ($reactPromise) {
+    // Do something something with the value...
+    // Return the React promise
+    return $reactPromise;
+});
+```
+
+Please note that wait and cancel chaining is no longer possible when forwarding
+a foreign promise. You will need to wrap a third-party promise with a Guzzle
+promise in order to utilize wait and cancel functions with foreign promises.
+
+
+## Event Loop Integration
+
+In order to keep the stack size constant, Guzzle promises are resolved
+asynchronously using a task queue. When waiting on promises synchronously, the
+task queue will be automatically run to ensure that the blocking promise and
+any forwarded promises are resolved. When using promises asynchronously in an
+event loop, you will need to run the task queue on each tick of the loop. If
+you do not run the task queue, then promises will not be resolved.
+
+You can run the task queue using the `run()` method of the global task queue
+instance.
+
+```php
+// Get the global task queue
+$queue = \GuzzleHttp\Promise\queue();
+$queue->run();
+```
+
+For example, you could use Guzzle promises with React using a periodic timer:
+
+```php
+$loop = React\EventLoop\Factory::create();
+$loop->addPeriodicTimer(0, [$queue, 'run']);
+```
+
+*TODO*: Perhaps adding a `futureTick()` on each tick would be faster?
+
+
+# Implementation notes
+
+
+## Promise resolution and chaining is handled iteratively
+
+By shuffling pending handlers from one owner to another, promises are
+resolved iteratively, allowing for "infinite" then chaining.
+
+```php
+<?php
+require 'vendor/autoload.php';
+
+use GuzzleHttp\Promise\Promise;
+
+$parent = new Promise();
+$p = $parent;
+
+for ($i = 0; $i < 1000; $i++) {
+    $p = $p->then(function ($v) {
+        // The stack size remains constant (a good thing)
+        echo xdebug_get_stack_depth() . ', ';
+        return $v + 1;
+    });
+}
+
+$parent->resolve(0);
+var_dump($p->wait()); // int(1000)
+
+```
+
+When a promise is fulfilled or rejected with a non-promise value, the promise
+then takes ownership of the handlers of each child promise and delivers values
+down the chain without using recursion.
+
+When a promise is resolved with another promise, the original promise transfers
+all of its pending handlers to the new promise. When the new promise is
+eventually resolved, all of the pending handlers are delivered the forwarded
+value.
+
+
+## A promise is the deferred.
+
+Some promise libraries implement promises using a deferred object to represent
+a computation and a promise object to represent the delivery of the result of
+the computation. This is a nice separation of computation and delivery because
+consumers of the promise cannot modify the value that will be eventually
+delivered.
+
+One side effect of being able to implement promise resolution and chaining
+iteratively is that you need to be able for one promise to reach into the state
+of another promise to shuffle around ownership of handlers. In order to achieve
+this without making the handlers of a promise publicly mutable, a promise is
+also the deferred value, allowing promises of the same parent class to reach
+into and modify the private properties of promises of the same type. While this
+does allow consumers of the value to modify the resolution or rejection of the
+deferred, it is a small price to pay for keeping the stack size constant.
+
+```php
+$promise = new Promise();
+$promise->then(function ($value) { echo $value; });
+// The promise is the deferred value, so you can deliver a value to it.
+$promise->resolve('foo');
+// prints "foo"
+```

+# Change Log
+
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/)
+and this project adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html).
+
+
+## [Unreleased]
+
+
+## [1.6.0]
+
+### Added
+
+- Allowed version `^3.0` of `ralouphie/getallheaders` dependency (#244)
+- Added MIME type for WEBP image format (#246)
+- Added more validation of values according to PSR-7 and RFC standards, e.g. status code range (#250, #272)
+
+### Changed
+
+- Tests don't pass with HHVM 4.0, so HHVM support got dropped. Other libraries like composer have done the same. (#262)
+- Accept port number 0 to be valid (#270)
+
+### Fixed
+
+- Fixed subsequent reads from `php://input` in ServerRequest (#247)
+- Fixed readable/writable detection for certain stream modes (#248)
+- Fixed encoding of special characters in the `userInfo` component of an URI (#253)
+
+
+## [1.5.2] - 2018-12-04
+
+### Fixed
+
+- Check body size when getting the message summary
+
+
+## [1.5.1] - 2018-12-04
+
+### Fixed
+
+- Get the summary of a body only if it is readable
+
+
+## [1.5.0] - 2018-12-03
+
+### Added
+
+- Response first-line to response string exception (fixes #145)
+- A test for #129 behavior
+- `get_message_body_summary` function in order to get the message summary
+- `3gp` and `mkv` mime types
+
+### Changed
+
+- Clarify exception message when stream is detached
+
+### Deprecated
+
+- Deprecated parsing folded header lines as per RFC 7230
+
+### Fixed
+
+- Fix `AppendStream::detach` to not close streams
+- `InflateStream` preserves `isSeekable` attribute of the underlying stream
+- `ServerRequest::getUriFromGlobals` to support URLs in query parameters
+
+
+Several other fixes and improvements.
+
+
+## [1.4.2] - 2017-03-20
+
+### Fixed
+
+- Reverted BC break to `Uri::resolve` and `Uri::removeDotSegments` by removing
+  calls to `trigger_error` when deprecated methods are invoked.
+
+
+## [1.4.1] - 2017-02-27
+
+### Added
+
+- Rriggering of silenced deprecation warnings.
+
+### Fixed
+
+- Reverted BC break by reintroducing behavior to automagically fix a URI with a
+  relative path and an authority by adding a leading slash to the path. It's only
+  deprecated now.
+
+
+## [1.4.0] - 2017-02-21
+
+### Added
+
+- Added common URI utility methods based on RFC 3986 (see documentation in the readme):
+  - `Uri::isDefaultPort`
+  - `Uri::isAbsolute`
+  - `Uri::isNetworkPathReference`
+  - `Uri::isAbsolutePathReference`
+  - `Uri::isRelativePathReference`
+  - `Uri::isSameDocumentReference`
+  - `Uri::composeComponents`
+  - `UriNormalizer::normalize`
+  - `UriNormalizer::isEquivalent`
+  - `UriResolver::relativize`
+
+### Changed
+
+- Ensure `ServerRequest::getUriFromGlobals` returns a URI in absolute form.
+- Allow `parse_response` to parse a response without delimiting space and reason.
+- Ensure each URI modification results in a valid URI according to PSR-7 discussions.
+  Invalid modifications will throw an exception instead of returning a wrong URI or
+  doing some magic.
+  - `(new Uri)->withPath('foo')->withHost('example.com')` will throw an exception
+    because the path of a URI with an authority must start with a slash "/" or be empty
+  - `(new Uri())->withScheme('http')` will return `'http://localhost'`
+
+### Deprecated
+
+- `Uri::resolve` in favor of `UriResolver::resolve`
+- `Uri::removeDotSegments` in favor of `UriResolver::removeDotSegments`
+
+### Fixed
+
+- `Stream::read` when length parameter <= 0.
+- `copy_to_stream` reads bytes in chunks instead of `maxLen` into memory.
+- `ServerRequest::getUriFromGlobals` when `Host` header contains port.
+- Compatibility of URIs with `file` scheme and empty host.
+
+
+## [1.3.1] - 2016-06-25
+
+### Fixed
+
+- `Uri::__toString` for network path references, e.g. `//example.org`.
+- Missing lowercase normalization for host.
+- Handling of URI components in case they are `'0'` in a lot of places,
+  e.g. as a user info password.
+- `Uri::withAddedHeader` to correctly merge headers with different case.
+- Trimming of header values in `Uri::withAddedHeader`. Header values may
+  be surrounded by whitespace which should be ignored according to RFC 7230
+  Section 3.2.4. This does not apply to header names.
+- `Uri::withAddedHeader` with an array of header values.
+- `Uri::resolve` when base path has no slash and handling of fragment.
+- Handling of encoding in `Uri::with(out)QueryValue` so one can pass the
+  key/value both in encoded as well as decoded form to those methods. This is
+  consistent with withPath, withQuery etc.
+- `ServerRequest::withoutAttribute` when attribute value is null.
+
+
+## [1.3.0] - 2016-04-13
+
+### Added
+
+- Remaining interfaces needed for full PSR7 compatibility
+  (ServerRequestInterface, UploadedFileInterface, etc.).
+- Support for stream_for from scalars.
+
+### Changed
+
+- Can now extend Uri.
+
+### Fixed
+- A bug in validating request methods by making it more permissive.
+
+
+## [1.2.3] - 2016-02-18
+
+### Fixed
+
+- Support in `GuzzleHttp\Psr7\CachingStream` for seeking forward on remote
+  streams, which can sometimes return fewer bytes than requested with `fread`.
+- Handling of gzipped responses with FNAME headers.
+
+
+## [1.2.2] - 2016-01-22
+
+### Added
+
+- Support for URIs without any authority.
+- Support for HTTP 451 'Unavailable For Legal Reasons.'
+- Support for using '0' as a filename.
+- Support for including non-standard ports in Host headers.
+
+
+## [1.2.1] - 2015-11-02
+
+### Changes
+
+- Now supporting negative offsets when seeking to SEEK_END.
+
+
+## [1.2.0] - 2015-08-15
+
+### Changed
+
+- Body as `"0"` is now properly added to a response.
+- Now allowing forward seeking in CachingStream.
+- Now properly parsing HTTP requests that contain proxy targets in
+  `parse_request`.
+- functions.php is now conditionally required.
+- user-info is no longer dropped when resolving URIs.
+
+
+## [1.1.0] - 2015-06-24
+
+### Changed
+
+- URIs can now be relative.
+- `multipart/form-data` headers are now overridden case-insensitively.
+- URI paths no longer encode the following characters because they are allowed
+  in URIs: "(", ")", "*", "!", "'"
+- A port is no longer added to a URI when the scheme is missing and no port is
+  present.
+
+
+## 1.0.0 - 2015-05-19
+
+Initial release.
+
+Currently unsupported:
+
+- `Psr\Http\Message\ServerRequestInterface`
+- `Psr\Http\Message\UploadedFileInterface`
+

+# PSR-7 Message Implementation
+
+This repository contains a full [PSR-7](http://www.php-fig.org/psr/psr-7/)
+message implementation, several stream decorators, and some helpful
+functionality like query string parsing.
+
+
+[![Build Status](https://travis-ci.org/guzzle/psr7.svg?branch=master)](https://travis-ci.org/guzzle/psr7)
+
+
+# Stream implementation
+
+This package comes with a number of stream implementations and stream
+decorators.
+
+
+## AppendStream
+
+`GuzzleHttp\Psr7\AppendStream`
+
+Reads from multiple streams, one after the other.
+
+```php
+use GuzzleHttp\Psr7;
+
+$a = Psr7\stream_for('abc, ');
+$b = Psr7\stream_for('123.');
+$composed = new Psr7\AppendStream([$a, $b]);
+
+$composed->addStream(Psr7\stream_for(' Above all listen to me'));
+
+echo $composed; // abc, 123. Above all listen to me.
+```
+
+
+## BufferStream
+
+`GuzzleHttp\Psr7\BufferStream`
+
+Provides a buffer stream that can be written to fill a buffer, and read
+from to remove bytes from the buffer.
+
+This stream returns a "hwm" metadata value that tells upstream consumers
+what the configured high water mark of the stream is, or the maximum
+preferred size of the buffer.
+
+```php
+use GuzzleHttp\Psr7;
+
+// When more than 1024 bytes are in the buffer, it will begin returning
+// false to writes. This is an indication that writers should slow down.
+$buffer = new Psr7\BufferStream(1024);
+```
+
+
+## CachingStream
+
+The CachingStream is used to allow seeking over previously read bytes on
+non-seekable streams. This can be useful when transferring a non-seekable
+entity body fails due to needing to rewind the stream (for example, resulting
+from a redirect). Data that is read from the remote stream will be buffered in
+a PHP temp stream so that previously read bytes are cached first in memory,
+then on disk.
+
+```php
+use GuzzleHttp\Psr7;
+
+$original = Psr7\stream_for(fopen('http://www.google.com', 'r'));
+$stream = new Psr7\CachingStream($original);
+
+$stream->read(1024);
+echo $stream->tell();
+// 1024
+
+$stream->seek(0);
+echo $stream->tell();
+// 0
+```
+
+
+## DroppingStream
+
+`GuzzleHttp\Psr7\DroppingStream`
+
+Stream decorator that begins dropping data once the size of the underlying
+stream becomes too full.
+
+```php
+use GuzzleHttp\Psr7;
+
+// Create an empty stream
+$stream = Psr7\stream_for();
+
+// Start dropping data when the stream has more than 10 bytes
+$dropping = new Psr7\DroppingStream($stream, 10);
+
+$dropping->write('01234567890123456789');
+echo $stream; // 0123456789
+```
+
+
+## FnStream
+
+`GuzzleHttp\Psr7\FnStream`
+
+Compose stream implementations based on a hash of functions.
+
+Allows for easy testing and extension of a provided stream without needing
+to create a concrete class for a simple extension point.
+
+```php
+
+use GuzzleHttp\Psr7;
+
+$stream = Psr7\stream_for('hi');
+$fnStream = Psr7\FnStream::decorate($stream, [
+    'rewind' => function () use ($stream) {
+        echo 'About to rewind - ';
+        $stream->rewind();
+        echo 'rewound!';
+    }
+]);
+
+$fnStream->rewind();
+// Outputs: About to rewind - rewound!
+```
+
+
+## InflateStream
+
+`GuzzleHttp\Psr7\InflateStream`
+
+Uses PHP's zlib.inflate filter to inflate deflate or gzipped content.
+
+This stream decorator skips the first 10 bytes of the given stream to remove
+the gzip header, converts the provided stream to a PHP stream resource,
+then appends the zlib.inflate filter. The stream is then converted back
+to a Guzzle stream resource to be used as a Guzzle stream.
+
+
+## LazyOpenStream
+
+`GuzzleHttp\Psr7\LazyOpenStream`
+
+Lazily reads or writes to a file that is opened only after an IO operation
+take place on the stream.
+
+```php
+use GuzzleHttp\Psr7;
+
+$stream = new Psr7\LazyOpenStream('/path/to/file', 'r');
+// The file has not yet been opened...
+
+echo $stream->read(10);
+// The file is opened and read from only when needed.
+```
+
+
+## LimitStream
+
+`GuzzleHttp\Psr7\LimitStream`
+
+LimitStream can be used to read a subset or slice of an existing stream object.
+This can be useful for breaking a large file into smaller pieces to be sent in
+chunks (e.g. Amazon S3's multipart upload API).
+
+```php
+use GuzzleHttp\Psr7;
+
+$original = Psr7\stream_for(fopen('/tmp/test.txt', 'r+'));
+echo $original->getSize();
+// >>> 1048576
+
+// Limit the size of the body to 1024 bytes and start reading from byte 2048
+$stream = new Psr7\LimitStream($original, 1024, 2048);
+echo $stream->getSize();
+// >>> 1024
+echo $stream->tell();
+// >>> 0
+```
+
+
+## MultipartStream
+
+`GuzzleHttp\Psr7\MultipartStream`
+
+Stream that when read returns bytes for a streaming multipart or
+multipart/form-data stream.
+
+
+## NoSeekStream
+
+`GuzzleHttp\Psr7\NoSeekStream`
+
+NoSeekStream wraps a stream and does not allow seeking.
+
+```php
+use GuzzleHttp\Psr7;
+
+$original = Psr7\stream_for('foo');
+$noSeek = new Psr7\NoSeekStream($original);
+
+echo $noSeek->read(3);
+// foo
+var_export($noSeek->isSeekable());
+// false
+$noSeek->seek(0);
+var_export($noSeek->read(3));
+// NULL
+```
+
+
+## PumpStream
+
+`GuzzleHttp\Psr7\PumpStream`
+
+Provides a read only stream that pumps data from a PHP callable.
+
+When invoking the provided callable, the PumpStream will pass the amount of
+data requested to read to the callable. The callable can choose to ignore
+this value and return fewer or more bytes than requested. Any extra data
+returned by the provided callable is buffered internally until drained using
+the read() function of the PumpStream. The provided callable MUST return
+false when there is no more data to read.
+
+
+## Implementing stream decorators
+
+Creating a stream decorator is very easy thanks to the
+`GuzzleHttp\Psr7\StreamDecoratorTrait`. This trait provides methods that
+implement `Psr\Http\Message\StreamInterface` by proxying to an underlying
+stream. Just `use` the `StreamDecoratorTrait` and implement your custom
+methods.
+
+For example, let's say we wanted to call a specific function each time the last
+byte is read from a stream. This could be implemented by overriding the
+`read()` method.
+
+```php
+use Psr\Http\Message\StreamInterface;
+use GuzzleHttp\Psr7\StreamDecoratorTrait;
+
+class EofCallbackStream implements StreamInterface
+{
+    use StreamDecoratorTrait;
+
+    private $callback;
+
+    public function __construct(StreamInterface $stream, callable $cb)
+    {
+        $this->stream = $stream;
+        $this->callback = $cb;
+    }
+
+    public function read($length)
+    {
+        $result = $this->stream->read($length);
+
+        // Invoke the callback when EOF is hit.
+        if ($this->eof()) {
+            call_user_func($this->callback);
+        }
+
+        return $result;
+    }
+}
+```
+
+This decorator could be added to any existing stream and used like so:
+
+```php
+use GuzzleHttp\Psr7;
+
+$original = Psr7\stream_for('foo');
+
+$eofStream = new EofCallbackStream($original, function () {
+    echo 'EOF!';
+});
+
+$eofStream->read(2);
+$eofStream->read(1);
+// echoes "EOF!"
+$eofStream->seek(0);
+$eofStream->read(3);
+// echoes "EOF!"
+```
+
+
+## PHP StreamWrapper
+
+You can use the `GuzzleHttp\Psr7\StreamWrapper` class if you need to use a
+PSR-7 stream as a PHP stream resource.
+
+Use the `GuzzleHttp\Psr7\StreamWrapper::getResource()` method to create a PHP
+stream from a PSR-7 stream.
+
+```php
+use GuzzleHttp\Psr7\StreamWrapper;
+
+$stream = GuzzleHttp\Psr7\stream_for('hello!');
+$resource = StreamWrapper::getResource($stream);
+echo fread($resource, 6); // outputs hello!
+```
+
+
+# Function API
+
+There are various functions available under the `GuzzleHttp\Psr7` namespace.
+
+
+## `function str`
+
+`function str(MessageInterface $message)`
+
+Returns the string representation of an HTTP message.
+
+```php
+$request = new GuzzleHttp\Psr7\Request('GET', 'http://example.com');
+echo GuzzleHttp\Psr7\str($request);
+```
+
+
+## `function uri_for`
+
+`function uri_for($uri)`
+
+This function accepts a string or `Psr\Http\Message\UriInterface` and returns a
+UriInterface for the given value. If the value is already a `UriInterface`, it
+is returned as-is.
+
+```php
+$uri = GuzzleHttp\Psr7\uri_for('http://example.com');
+assert($uri === GuzzleHttp\Psr7\uri_for($uri));
+```
+
+
+## `function stream_for`
+
+`function stream_for($resource = '', array $options = [])`
+
+Create a new stream based on the input type.
+
+Options is an associative array that can contain the following keys:
+
+* - metadata: Array of custom metadata.
+* - size: Size of the stream.
+
+This method accepts the following `$resource` types:
+
+- `Psr\Http\Message\StreamInterface`: Returns the value as-is.
+- `string`: Creates a stream object that uses the given string as the contents.
+- `resource`: Creates a stream object that wraps the given PHP stream resource.
+- `Iterator`: If the provided value implements `Iterator`, then a read-only
+  stream object will be created that wraps the given iterable. Each time the
+  stream is read from, data from the iterator will fill a buffer and will be
+  continuously called until the buffer is equal to the requested read size.
+  Subsequent read calls will first read from the buffer and then call `next`
+  on the underlying iterator until it is exhausted.
+- `object` with `__toString()`: If the object has the `__toString()` method,
+  the object will be cast to a string and then a stream will be returned that
+  uses the string value.
+- `NULL`: When `null` is passed, an empty stream object is returned.
+- `callable` When a callable is passed, a read-only stream object will be
+  created that invokes the given callable. The callable is invoked with the
+  number of suggested bytes to read. The callable can return any number of
+  bytes, but MUST return `false` when there is no more data to return. The
+  stream object that wraps the callable will invoke the callable until the
+  number of requested bytes are available. Any additional bytes will be
+  buffered and used in subsequent reads.
+
+```php
+$stream = GuzzleHttp\Psr7\stream_for('foo');
+$stream = GuzzleHttp\Psr7\stream_for(fopen('/path/to/file', 'r'));
+
+$generator = function ($bytes) {
+    for ($i = 0; $i < $bytes; $i++) {
+        yield ' ';
+    }
+}
+
+$stream = GuzzleHttp\Psr7\stream_for($generator(100));
+```
+
+
+## `function parse_header`
+
+`function parse_header($header)`
+
+Parse an array of header values containing ";" separated data into an array of
+associative arrays representing the header key value pair data of the header.
+When a parameter does not contain a value, but just contains a key, this
+function will inject a key with a '' string value.
+
+
+## `function normalize_header`
+
+`function normalize_header($header)`
+
+Converts an array of header values that may contain comma separated headers
+into an array of headers with no comma separated values.
+
+
+## `function modify_request`
+
+`function modify_request(RequestInterface $request, array $changes)`
+
+Clone and modify a request with the given changes. This method is useful for
+reducing the number of clones needed to mutate a message.
+
+The changes can be one of:
+
+- method: (string) Changes the HTTP method.
+- set_headers: (array) Sets the given headers.
+- remove_headers: (array) Remove the given headers.
+- body: (mixed) Sets the given body.
+- uri: (UriInterface) Set the URI.
+- query: (string) Set the query string value of the URI.
+- version: (string) Set the protocol version.
+
+
+## `function rewind_body`
+
+`function rewind_body(MessageInterface $message)`
+
+Attempts to rewind a message body and throws an exception on failure. The body
+of the message will only be rewound if a call to `tell()` returns a value other
+than `0`.
+
+
+## `function try_fopen`
+
+`function try_fopen($filename, $mode)`
+
+Safely opens a PHP stream resource using a filename.
+
+When fopen fails, PHP normally raises a warning. This function adds an error
+handler that checks for errors and throws an exception instead.
+
+
+## `function copy_to_string`
+
+`function copy_to_string(StreamInterface $stream, $maxLen = -1)`
+
+Copy the contents of a stream into a string until the given number of bytes
+have been read.
+
+
+## `function copy_to_stream`
+
+`function copy_to_stream(StreamInterface $source, StreamInterface $dest, $maxLen = -1)`
+
+Copy the contents of a stream into another stream until the given number of
+bytes have been read.
+
+
+## `function hash`
+
+`function hash(StreamInterface $stream, $algo, $rawOutput = false)`
+
+Calculate a hash of a Stream. This method reads the entire stream to calculate
+a rolling hash (based on PHP's hash_init functions).
+
+
+## `function readline`
+
+`function readline(StreamInterface $stream, $maxLength = null)`
+
+Read a line from the stream up to the maximum allowed buffer length.
+
+
+## `function parse_request`
+
+`function parse_request($message)`
+
+Parses a request message string into a request object.
+
+
+## `function parse_response`
+
+`function parse_response($message)`
+
+Parses a response message string into a response object.
+
+
+## `function parse_query`
+
+`function parse_query($str, $urlEncoding = true)`
+
+Parse a query string into an associative array.
+
+If multiple values are found for the same key, the value of that key value pair
+will become an array. This function does not parse nested PHP style arrays into
+an associative array (e.g., `foo[a]=1&foo[b]=2` will be parsed into
+`['foo[a]' => '1', 'foo[b]' => '2']`).
+
+
+## `function build_query`
+
+`function build_query(array $params, $encoding = PHP_QUERY_RFC3986)`
+
+Build a query string from an array of key value pairs.
+
+This function can use the return value of parse_query() to build a query string.
+This function does not modify the provided keys when an array is encountered
+(like http_build_query would).
+
+
+## `function mimetype_from_filename`
+
+`function mimetype_from_filename($filename)`
+
+Determines the mimetype of a file by looking at its extension.
+
+
+## `function mimetype_from_extension`
+
+`function mimetype_from_extension($extension)`
+
+Maps a file extensions to a mimetype.
+
+
+# Additional URI Methods
+
+Aside from the standard `Psr\Http\Message\UriInterface` implementation in form of the `GuzzleHttp\Psr7\Uri` class,
+this library also provides additional functionality when working with URIs as static methods.
+
+## URI Types
+
+An instance of `Psr\Http\Message\UriInterface` can either be an absolute URI or a relative reference.
+An absolute URI has a scheme. A relative reference is used to express a URI relative to another URI,
+the base URI. Relative references can be divided into several forms according to
+[RFC 3986 Section 4.2](https://tools.ietf.org/html/rfc3986#section-4.2):
+
+- network-path references, e.g. `//example.com/path`
+- absolute-path references, e.g. `/path`
+- relative-path references, e.g. `subpath`
+
+The following methods can be used to identify the type of the URI.
+
+### `GuzzleHttp\Psr7\Uri::isAbsolute`
+
+`public static function isAbsolute(UriInterface $uri): bool`
+
+Whether the URI is absolute, i.e. it has a scheme.
+
+### `GuzzleHttp\Psr7\Uri::isNetworkPathReference`
+
+`public static function isNetworkPathReference(UriInterface $uri): bool`
+
+Whether the URI is a network-path reference. A relative reference that begins with two slash characters is
+termed an network-path reference.
+
+### `GuzzleHttp\Psr7\Uri::isAbsolutePathReference`
+
+`public static function isAbsolutePathReference(UriInterface $uri): bool`
+
+Whether the URI is a absolute-path reference. A relative reference that begins with a single slash character is
+termed an absolute-path reference.
+
+### `GuzzleHttp\Psr7\Uri::isRelativePathReference`
+
+`public static function isRelativePathReference(UriInterface $uri): bool`
+
+Whether the URI is a relative-path reference. A relative reference that does not begin with a slash character is
+termed a relative-path reference.
+
+### `GuzzleHttp\Psr7\Uri::isSameDocumentReference`
+
+`public static function isSameDocumentReference(UriInterface $uri, UriInterface $base = null): bool`
+
+Whether the URI is a same-document reference. A same-document reference refers to a URI that is, aside from its
+fragment component, identical to the base URI. When no base URI is given, only an empty URI reference
+(apart from its fragment) is considered a same-document reference.
+
+## URI Components
+
+Additional methods to work with URI components.
+
+### `GuzzleHttp\Psr7\Uri::isDefaultPort`
+
+`public static function isDefaultPort(UriInterface $uri): bool`
+
+Whether the URI has the default port of the current scheme. `Psr\Http\Message\UriInterface::getPort` may return null
+or the standard port. This method can be used independently of the implementation.
+
+### `GuzzleHttp\Psr7\Uri::composeComponents`
+
+`public static function composeComponents($scheme, $authority, $path, $query, $fragment): string`
+
+Composes a URI reference string from its various components according to
+[RFC 3986 Section 5.3](https://tools.ietf.org/html/rfc3986#section-5.3). Usually this method does not need to be called
+manually but instead is used indirectly via `Psr\Http\Message\UriInterface::__toString`.
+
+### `GuzzleHttp\Psr7\Uri::fromParts`
+
+`public static function fromParts(array $parts): UriInterface`
+
+Creates a URI from a hash of [`parse_url`](http://php.net/manual/en/function.parse-url.php) components.
+
+
+### `GuzzleHttp\Psr7\Uri::withQueryValue`
+
+`public static function withQueryValue(UriInterface $uri, $key, $value): UriInterface`
+
+Creates a new URI with a specific query string value. Any existing query string values that exactly match the
+provided key are removed and replaced with the given key value pair. A value of null will set the query string
+key without a value, e.g. "key" instead of "key=value".
+
+### `GuzzleHttp\Psr7\Uri::withQueryValues`
+
+`public static function withQueryValues(UriInterface $uri, array $keyValueArray): UriInterface`
+
+Creates a new URI with multiple query string values. It has the same behavior as `withQueryValue()` but for an
+associative array of key => value.
+
+### `GuzzleHttp\Psr7\Uri::withoutQueryValue`
+
+`public static function withoutQueryValue(UriInterface $uri, $key): UriInterface`
+
+Creates a new URI with a specific query string value removed. Any existing query string values that exactly match the
+provided key are removed.
+
+## Reference Resolution
+
+`GuzzleHttp\Psr7\UriResolver` provides methods to resolve a URI reference in the context of a base URI according
+to [RFC 3986 Section 5](https://tools.ietf.org/html/rfc3986#section-5). This is for example also what web browsers
+do when resolving a link in a website based on the current request URI.
+
+### `GuzzleHttp\Psr7\UriResolver::resolve`
+
+`public static function resolve(UriInterface $base, UriInterface $rel): UriInterface`
+
+Converts the relative URI into a new URI that is resolved against the base URI.
+
+### `GuzzleHttp\Psr7\UriResolver::removeDotSegments`
+
+`public static function removeDotSegments(string $path): string`
+
+Removes dot segments from a path and returns the new path according to
+[RFC 3986 Section 5.2.4](https://tools.ietf.org/html/rfc3986#section-5.2.4).
+
+### `GuzzleHttp\Psr7\UriResolver::relativize`
+
+`public static function relativize(UriInterface $base, UriInterface $target): UriInterface`
+
+Returns the target URI as a relative reference from the base URI. This method is the counterpart to resolve():
+
+```php
+(string) $target === (string) UriResolver::resolve($base, UriResolver::relativize($base, $target))
+```
+
+One use-case is to use the current request URI as base URI and then generate relative links in your documents
+to reduce the document size or offer self-contained downloadable document archives.
+
+```php
+$base = new Uri('http://example.com/a/b/');
+echo UriResolver::relativize($base, new Uri('http://example.com/a/b/c'));  // prints 'c'.
+echo UriResolver::relativize($base, new Uri('http://example.com/a/x/y'));  // prints '../x/y'.
+echo UriResolver::relativize($base, new Uri('http://example.com/a/b/?q')); // prints '?q'.
+echo UriResolver::relativize($base, new Uri('http://example.org/a/b/'));   // prints '//example.org/a/b/'.
+```
+
+## Normalization and Comparison
+
+`GuzzleHttp\Psr7\UriNormalizer` provides methods to normalize and compare URIs according to
+[RFC 3986 Section 6](https://tools.ietf.org/html/rfc3986#section-6).
+
+### `GuzzleHttp\Psr7\UriNormalizer::normalize`
+
+`public static function normalize(UriInterface $uri, $flags = self::PRESERVING_NORMALIZATIONS): UriInterface`
+
+Returns a normalized URI. The scheme and host component are already normalized to lowercase per PSR-7 UriInterface.
+This methods adds additional normalizations that can be configured with the `$flags` parameter which is a bitmask
+of normalizations to apply. The following normalizations are available:
+
+- `UriNormalizer::PRESERVING_NORMALIZATIONS`
+
+    Default normalizations which only include the ones that preserve semantics.
+
+- `UriNormalizer::CAPITALIZE_PERCENT_ENCODING`
+
+    All letters within a percent-encoding triplet (e.g., "%3A") are case-insensitive, and should be capitalized.
+
+    Example: `http://example.org/a%c2%b1b` → `http://example.org/a%C2%B1b`
+
+- `UriNormalizer::DECODE_UNRESERVED_CHARACTERS`
+
+    Decodes percent-encoded octets of unreserved characters. For consistency, percent-encoded octets in the ranges of
+    ALPHA (%41–%5A and %61–%7A), DIGIT (%30–%39), hyphen (%2D), period (%2E), underscore (%5F), or tilde (%7E) should
+    not be created by URI producers and, when found in a URI, should be decoded to their corresponding unreserved
+    characters by URI normalizers.
+
+    Example: `http://example.org/%7Eusern%61me/` → `http://example.org/~username/`
+
+- `UriNormalizer::CONVERT_EMPTY_PATH`
+
+    Converts the empty path to "/" for http and https URIs.
+
+    Example: `http://example.org` → `http://example.org/`
+
+- `UriNormalizer::REMOVE_DEFAULT_HOST`
+
+    Removes the default host of the given URI scheme from the URI. Only the "file" scheme defines the default host
+    "localhost". All of `file:/myfile`, `file:///myfile`, and `file://localhost/myfile` are equivalent according to
+    RFC 3986.
+
+    Example: `file://localhost/myfile` → `file:///myfile`
+
+- `UriNormalizer::REMOVE_DEFAULT_PORT`
+
+    Removes the default port of the given URI scheme from the URI.
+
+    Example: `http://example.org:80/` → `http://example.org/`
+
+- `UriNormalizer::REMOVE_DOT_SEGMENTS`
+
+    Removes unnecessary dot-segments. Dot-segments in relative-path references are not removed as it would
+    change the semantics of the URI reference.
+
+    Example: `http://example.org/../a/b/../c/./d.html` → `http://example.org/a/c/d.html`
+
+- `UriNormalizer::REMOVE_DUPLICATE_SLASHES`
+
+    Paths which include two or more adjacent slashes are converted to one. Webservers usually ignore duplicate slashes
+    and treat those URIs equivalent. But in theory those URIs do not need to be equivalent. So this normalization
+    may change the semantics. Encoded slashes (%2F) are not removed.
+
+    Example: `http://example.org//foo///bar.html` → `http://example.org/foo/bar.html`
+
+- `UriNormalizer::SORT_QUERY_PARAMETERS`
+
+    Sort query parameters with their values in alphabetical order. However, the order of parameters in a URI may be
+    significant (this is not defined by the standard). So this normalization is not safe and may change the semantics
+    of the URI.
+
+    Example: `?lang=en&article=fred` → `?article=fred&lang=en`
+
+### `GuzzleHttp\Psr7\UriNormalizer::isEquivalent`
+
+`public static function isEquivalent(UriInterface $uri1, UriInterface $uri2, $normalizations = self::PRESERVING_NORMALIZATIONS): bool`
+
+Whether two URIs can be considered equivalent. Both URIs are normalized automatically before comparison with the given
+`$normalizations` bitmask. The method also accepts relative URI references and returns true when they are equivalent.
+This of course assumes they will be resolved against the same base URI. If this is not the case, determination of
+equivalence or difference of relative references does not mean anything.

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.

+# LazyJsonMapper
+
+## Advanced, intelligent & automatic object-oriented JSON containers for PHP.
+
+Implements a highly efficient, automatic, object-oriented and lightweight
+(memory-wise) JSON data container. It provides intelligent data conversion
+and parsing, to give you a nice, reliable interface to your JSON data,
+without having to worry about doing any of the tedious parsing yourself.
+
+### Features:
+
+- Provides a completely object-oriented interface to all of your JSON data.
+
+- Automatically maps complex, nested JSON data structures onto real PHP
+  objects, with total support for nested objects and multi-level arrays.
+
+- Extremely optimized for very high performance and very low memory usage.
+  Much lower than other PHP JSON mappers that people have used in the past.
+
+  For example, normal PHP objects with manually defined `$properties`, which
+  is what's used by _other_ JSON mappers, will consume memory for every
+  property even if that property wasn't in the JSON data (is a `NULL`). Our
+  system on the other hand takes up ZERO bytes of RAM for any properties
+  that don't exist in the current object's JSON data!
+
+- Automatically provides "direct virtual properties", which lets you
+  interact with the JSON data as if it were regular object properties,
+  such as `echo $item->some_value` and `$item->some_value = 'foo'`.
+
+  The virtual properties can be disabled via an option.
+
+- Automatically provides object-oriented "virtual functions", which let you
+  interact with the data in a fully object-oriented way via functions such
+  as `$item->getSomeValue()` and `$item->setSomeValue('foo')`. We support a
+  large range of different functions for manipulating the JSON data, and you
+  can see a list of all available function names for all of your properties
+  by simply running `$item->printPropertyDescriptions()`.
+
+  The virtual functions can be disabled via an option.
+
+- Includes the `LazyDoctor` tool, which _automatically_ documents all of
+  your `LazyJsonMapper`-based classes so that their virtual properties and
+  functions become _fully_ visible to your IDE and to various intelligent
+  code analysis tools. It also performs class diagnostics by compiling all
+  of your class property maps, which means that you can be 100% sure that
+  all of your maps are valid (compilable) if this tool runs successfully.
+
+- We provide a complete, internal API which your subclasses can use to
+  interact with the data inside of the JSON container. This allows you to
+  easily override the automatic functions or create additional functions
+  for your objects. To override core functions, just define a function with
+  the exact same name on your object and make it do whatever you want to.
+
+  Here are some examples of function overriding:
+
+    ```php
+    public function getFoo()
+    {
+        // try to read property, and handle a special "current_time" value.
+        $value = $this->_getProperty('foo');
+        if ($value === 'current_time') { return time(); }
+        return $value;
+    }
+    public function setFoo(
+        $value)
+    {
+        // if they try to set value to "md5", we use a special value instead
+        if ($value === 'md5') { $value = md5(time()); }
+        return $this->_setProperty('foo', $value);
+    }
+    ```
+
+- All mapping/data conversion is done "lazily", on a per-property basis.
+  When you access a property, that specific property is mapped/converted to
+  the proper type as defined by your class property map. No time or memory
+  is wasted converting properties that you never touch.
+
+- Strong type-system. The class property map controls the exact types and
+  array depths. You can fully trust that the data you get/set will match
+  your specifications. Invalid data that mismatches the spec is impossible.
+
+- Advanced settings system. Everything is easily configured via PHP class
+  constants, which means that your class-settings are stateless (there's no
+  need for any special "settings/mapper object" to keep track of settings),
+  and that all settings are immutable constants (which means that they are
+  reliable and can never mutate at runtime, so that you can fully trust that
+  classes will always behave as-defined in their code).
+
+  If you want to override multiple core settings identically for all of your
+  classes, then simply create a subclass of `LazyJsonMapper` and configure
+  all of your settings on that, and then derive all of your other classes
+  from your re-configured subclass!
+
+- The world's most advanced mapper definition system. Your class property
+  maps are defined in an easy PHPdoc-style format, and support multilevel
+  arrays (such as `int[][]` for "an array of arrays of ints"), relative
+  types (so you can map properties to classes/objects that are relative to
+  the namespace of the class property map), parent inheritance (all of your
+  parent `extends`-hierarchy's maps will be included in your final property
+  map) and even multiple inheritance (you can literally "import" an infinite
+  number of other maps into your class, which don't come from your own
+  parent `extends`-hierarchy).
+
+- Inheriting properties from parent classes or importing properties from
+  other classes is a zero-cost operation thanks to how efficient our
+  property map compiler is. So feel free to import everything you need.
+  You can even use this system to create importable classes that just hold
+  "collections" of shared properties, which you import into other classes.
+
+- The class property maps are compiled a single time per-class at runtime,
+  the first time a class is used. The compilation process fully verifies
+  and compiles all property definitions, all parent maps, all inherited
+  maps, and all maps of all classes you link properties to.
+
+  If there are any compilation problems due to a badly written map anywhere
+  in your hierarchy, you will be shown the exact problem in great detail.
+
+  In case of success, the compiled and verified maps are all stored in an
+  incredibly memory-efficient format in a global cache which is shared by
+  your whole PHP runtime, which means that anything in your code or in any
+  other libraries which accesses the same classes will all share the cached
+  compilations of those classes, for maximum memory efficiency.
+
+- You are also able to access JSON properties that haven't been defined in
+  the class property map. In that case, they are treated as undefined and
+  untyped (`mixed`) and there won't be any automatic type-conversion of such
+  properties, but it can still be handy in a pinch.
+
+- There are lots of data export/output options for your object's JSON data,
+  to get it back out of the object again: As a multi-level array, as nested
+  stdClass objects, or as a JSON string representation of your object.
+
+- We include a whole assortment of incredibly advanced debugging features:
+
+  You can run the constructor with `$requireAnalysis` to ensure that all
+  of your JSON data is successfully mapped according to your class property
+  map, and that you haven't missed defining any properties that exist in the
+  data. In case of any problems, the analysis message will give you a full
+  list of all problems encountered in your entire JSON data hierarchy.
+
+  For your class property maps themselves, you can run functions such as
+  `printPropertyDescriptions()` to see a complete list of all properties and
+  how they are defined. This helps debug your class inheritance and imports
+  to visually see what your final class map looks like, and it also helps
+  users see all available properties and all of their virtual functions.
+
+  And for the JSON data, you can use functions such as `printJson()` to get
+  a beautiful view of all internal JSON data, which is incredibly helpful
+  when you (or your users) need to figure out what's available inside the
+  current object instance's data storage.
+
+- A fine-grained and logical exception-system which ensures that you can
+  always trust the behavior of your objects and can catch problems easily.
+  And everything we throw is _always_ based on `LazyJsonMapperException`,
+  which means that you can simply catch that single "root" exception
+  whenever you don't care about fine-grained differentiation.
+
+- Clean and modular code ensures stability and future extensibility.
+
+- Deep code documentation explains everything you could ever wonder about.
+
+- Lastly, we implement super-efficient object serialization. Everything is
+  stored in a tightly packed format which minimizes data size when you need
+  to transfer your objects between runtimes.
+

+ * The Lazy Doctor.
+ *
+ * This tool automatically builds up-to-date class documentation for all classes
+ * that derive from LazyJsonMapper, and documents their virtual properties and
+ * functions by adding "@property" and "@method" declarations to their class
+ * PHPdoc blocks. That documentation is necessary for things like code analysis
+ * tools and IDE autocomplete for all of your virtual properties/functions!
+ *
+ * LazyDoctor also performs class diagnostics: It compiles the class property
+ * maps of _all_ of your LazyJsonMapper-based classes, which means that you can
+ * be 100% sure that all of your maps are valid if this tool runs successfully.
+ *
+ * To see all available options, type "./vendor/bin/lazydoctor --help".
+ *
+ * To begin, simply point the "--composer" option at the "composer.json" file
+ * for your project. Just be aware that your project MUST be based on PSR-4
+ * autoloading, with ONE OR MORE defined autoload-namespaces in "composer.json".
+ *
+ * You can read more about PSR-4 autoloading at the official Composer site:
+ *
+ * https://getcomposer.org/doc/04-schema.md#autoload
+ *
+ * This tool will ONLY parse classes that properly follow PSR-4 autoloading!
+ *
+ * In addition to the composer-file, you'll also have to specify whether you
+ * want to document virtual "--properties", virtual "--functions", or BOTH.
+ * Note that we'll ONLY document them when the individual classes support that
+ * kind of access (when it hasn't disabled its class-option for that feature).
+ *
+ * If you don't provide any documentation flags, we'll instead REMOVE all of
+ * the current class "virtual @property/@method" documentation. That can be
+ * useful for restoring your files if you don't want to document them anymore.
+ *
+ * You should also be aware of "--document-overridden", which will document
+ * virtual properties or functions even if they're already manually defined
+ * (overridden) by the class or its parents. That can be useful if you want to
+ * ensure that you ALWAYS document the virtual properties/functions in all of
+ * your class files even when it has been overridden somewhere. In that case,
+ * you should ensure that your overridden properties/functions have the SAME or
+ * a COMPATIBLE signature & return value, so their auto-docs are still correct.
+ *
+ * Tip: You can use the "--validate-only" param to check docs without writing to
+ * disk. That can be useful when making a non-destructive Git "pre-commit hook"
+ * to validate your repo and ensure that all files have updated documentation!
+ *
+ * This script always uses exit codes to indicate success. A non-zero exit code
+ * indicates that some files needed new class docs (in "--validate-only" mode),
+ * or that there was a general problem while processing.
+ *
+ * Lastly, you may appreciate the ability to silence all unimportant status
+ * messages! To do so, simply use ">/dev/null" to send STDOUT to the void...
+ * That way you'll ONLY see critical status messages during the processing.

+// tests during development of LazyJsonMapper... I barely even cared about
+// grammar since this file was just meant to dump a bunch of tests in and not
+// meant for public use. But it has so many extremely important tests that
+// cover all kinds of common and unusual scenarios. Several of the tests may
+// be outdated and test details that later changed during development. So
+// everything below needs to be carefully revised.
+//
+// We REALLY SHOULD rewrite everything as clean and organized PHPUnit tests...
+// if SOMEONE has the energy...
+//
+// PS: If anyone is using this library for commercial purposes, then a nice way
+// to contribute back as a "thank you!" would be to manually go through
+// everything below and rewrite relevant tests as beautiful PHPunit tests. :-)
+// If someone wants to contribute, you can do the test-rewrite step by step and
+// won't have to do everything all at once. ;-)

+/*
+ * I created these stack-based array loop algorithms for fun, just to try out
+ * an idea I had in mind. They are algorithms for iterating through multi-level
+ * arrays without needing any recursive function calls. And they are fully
+ * capable of tracking the current array-depth that they're operating at...
+ *
+ * These are the algorithms I tested:
+ * - RecursiveIteratorIterator = PHP's built-in object-based iterator library
+ * - array_flat_topdown_traverse = my stack-based algorithm v1
+ * - array_flat_topdown_traverse2 = my stack-based algorithm v2 (optimized)
+ * - array_recursive_traverse = simple recursive function calls
+ *
+ * The recursive function calls add 1 extra level to the call-stack for every
+ * deeper array depth-level that it enters.
+ *
+ * Therefore, I tested everything with test-data that contained array-depth 6
+ * (that's usually max in normal JSON data), 50 (rare), 500 (insane) and finally
+ * 5000 (hellish). The latter means that the recursive function calls-stack will
+ * reach a depth of 5000 recursive calls inside of each other. Hell indeed.
+ *
+ * The algorithms were a success; MASSIVELY beating `RecursiveIteratorIterator`
+ * from PHP's standard library by a factor of being almost 10x faster than it.
+ *
+ * Here's the fun thing, though: Simple, old-school recursive function-calls
+ * beats even my algorithm by a factor of being 2x faster!
+ *
+ * As for memory usage? The 500-levels deep recursive function calls didn't even
+ * make a noticeable blip on the radar...! They don't cause any stack memory
+ * overflows. On PHP5, this WHOLE test-script used 7.4 MB at peak while running
+ * all of the various tests. On PHP7, it used 4.7 MB at peak. And that's for the
+ * whole PHP binary, its runtime, etc! I didn't test the 5000-levels deep, but
+ * we'll never have such insane JSON data. So there's absolutely ZERO reason to
+ * worry about memory-usage of the recursive array resolver in LazyJsonMapper.
+ * Especially since normal JSON maps usually have 1-2 levels of array-depth. Now
+ * we know that we'll easily handle 500 levels or more. So no need to worry!
+ *
+ * Therefore there's no need to implement any kind of non-recursive resolver for
+ * array processing in this library! Recursive function calls are by far the
+ * fastest way to traverse the whole data array.
+ *
+ * I'll keep this test-file just in case anyone ever complains about the
+ * decision to use recursive function calls for the multi-level array
+ * processing in LazyJsonMapper.

+// into "get" and "SomethingSomething".
+//
+// This kind of micro-optimization is kind of overkill. But so is
+// everything else about the LazyJsonMapper project! ;-) And I was
+// curious about the performance implications of each method!
+//
+// NOTE about algorithm speed:
+// In all of these test algorithms I do a "get" check LAST, to
+// force PHP to check less common prefixes first, to ensure
+// that it fairly represents normal usage (since the test-data
+// overrepresents its amount of "get" functions and would therefore
+// usually short-circuit each test very quickly). in a real
+// algorithm, get should be first, since it's the most common prefix.

+// preg_split algorithm:
+// very fast. splits on the first non-lowercase ("not a-z") character.
+// never any false positives! the prefix-split is truly perfect,
+// so "getgetgetSomething" would split as "getgetget" and "Something".
+// this is basically like the preg_match, except that we do the split
+// and THEN use regular string comparison to check if the prefix
+// is a valid one. this has the benefit of allowing us to add lots
+// of other prefixes over time, without slowing down a preg_match
+// regex even more (since that one has to slowly look for EACH possible
+// prefix string repeatedly and requires far more regex engine steps).
+//
+// NOTE: in both PHP5 and PHP7, the preg_split method is almost exactly
+// 5x slower than isset(), but we're talking about microsecond level!
+// a microsecond is a MILLIONTH of a second. so I'm going to choose
+// the preg_split method. it saves tons of RAM compared to caching
+// EVERY individual exact function name via isset(). the only really
+// heavy part is the FuncCase-to-property_name translation from the
+// SomethingSomething part of "getSomethingSomething". so THAT is the
+// only part we really need to cache. This initial prefix-splitting
+// is better handled live on every function call to save RAM.
+//
+// benchmarks:
+// PHP7:
+// preg_split per item: 0.5883 Microseconds (0.0000005883 seconds)
+// isset() per item: 0.1053 Microseconds (0.0000001053 seconds)
+// PHP5:
+// preg_split per item: 2.3158 Microseconds (0.0000023158 seconds)
+// isset() per item: 0.4752 Microseconds (0.000004752 seconds)
+//
+// so for a ~5x increase in operation time at a microsecond-level,
+// we get MUCH LOWER RAM USAGE by only having to cache the shared
+// "SomethingSomething" part, rather than "getSomethingSomething",
+// "setSomethingSomething", "isSomethingSomething", "hasSomethingSomething"
+// and "unsetSomethingSomething".
+//
+// for someone using tens of thousands of calls, the prefix splitting
+// will be impressively instant. just try this file with $iterations = 1!
+// in that case, all of the prefix-splittings for 10,000 function
+// calls run in a COMBINED total of ~3.4 milliseconds! for ALL of them!
+// even in PHP5 it's around ~11 milliseconds for 10,000 prefix-splits.
+//
+// even if someone has millions of magic function calls, they won't
+// notice this preg_split() processing in relation to all of their
+// other processing when they have that many calls! that's how fast
+// the splitting is. and it saves 5x RAM at the moment (and even more
+// if more function prefix variations are added later).

+ * multiple great methods for working with objects that have unpredictable keys!
+ *
+ * There are other methods too, such as if your class contains a blend of known
+ * (defined) keys and unpredictable keys, in which case you'd need to fetch via
+ * `asArray()` as in the `UnpredictableContainer` example, and then you'd simply
+ * filter out all known keys from your cache, to get _just_ the unpredictable
+ * keys. And if you need setters in that scenario, your setter functions would
+ * be a bit more complex since they would need to use `assignObjectData()` AND
+ * would have to provide BOTH the known data AND the unknown data. One way of
+ * doing that would be to use `_getProperty()` to merge in the CURRENT values of
+ * each core property into your NEW object-data array BEFORE you assign it. But
+ * I leave that extremely rare scenario as an excercise for you, dear reader!
+ *
+ * You should go out and adapt all of this code to fit your own needs! ;-)
+ *
+ * For example, if you don't need the unpredictable values to be converted
+ * to/from a specific object type, then simply skip the conversion code.
+ *
+ * If you don't need caching for performance, then skip the caching code.
+ *
+ * If you don't need setters/syncing, then skip all of that code.
+ *
+ * You may also want to disable the user-options `ALLOW_VIRTUAL_PROPERTIES` and
+ * `ALLOW_VIRTUAL_FUNCTIONS` on your unpredictable containers, so users cannot
+ * manipulate the unpredictable data via LazyJsonMapper's automatic functions!
+ * That's what we did for CoreUnpredictableContainer, to ensure that nobody can
+ * destroy its internal data by touching it directly. They can only manipulate
+ * the data via its safe, public `getData()` and `setData()` functions!
+ *
+ * And you may perhaps prefer to write a custom base-class which has a few other
+ * helper-functions for doing these kinds of data translations, caching and
+ * syncing, to make your own work easier (such as the CoreUnpredictableContainer
+ * example above). That way, your various sub-classes could just call your
+ * internal helper functions to do the required processing automatically! :-)
+ *
+ * The possibilities are endless! Have fun!

+/**
+ * Advanced, intelligent & automatic object-oriented JSON containers for PHP.
+ *
+ * Implements a highly efficient, automatic, object-oriented and lightweight
+ * (memory-wise) JSON data container. It provides intelligent data conversion
+ * and parsing, to give you a nice, reliable interface to your JSON data,
+ * without having to worry about doing any of the tedious parsing yourself.
+ *
+ * Features:
+ *
+ *  - Provides a completely object-oriented interface to all of your JSON data.
+ *
+ *  - Automatically maps complex, nested JSON data structures onto real PHP
+ *    objects, with total support for nested objects and multi-level arrays.
+ *
+ *  - Extremely optimized for very high performance and very low memory usage.
+ *    Much lower than other PHP JSON mappers that people have used in the past.
+ *
+ *    For example, normal PHP objects with manually defined `$properties`, which
+ *    is what's used by _other_ JSON mappers, will consume memory for every
+ *    property even if that property wasn't in the JSON data (is a `NULL`). Our
+ *    system on the other hand takes up ZERO bytes of RAM for any properties
+ *    that don't exist in the current object's JSON data!
+ *
+ *  - Automatically provides "direct virtual properties", which lets you
+ *    interact with the JSON data as if it were regular object properties,
+ *    such as `echo $item->some_value` and `$item->some_value = 'foo'`.
+ *
+ *    The virtual properties can be disabled via an option.
+ *
+ *  - Automatically provides object-oriented "virtual functions", which let you
+ *    interact with the data in a fully object-oriented way via functions such
+ *    as `$item->getSomeValue()` and `$item->setSomeValue('foo')`. We support a
+ *    large range of different functions for manipulating the JSON data, and you
+ *    can see a list of all available function names for all of your properties
+ *    by simply running `$item->printPropertyDescriptions()`.
+ *
+ *    The virtual functions can be disabled via an option.
+ *
+ *  - Includes the `LazyDoctor` tool, which _automatically_ documents all of
+ *    your `LazyJsonMapper`-based classes so that their virtual properties and
+ *    functions become _fully_ visible to your IDE and to various intelligent
+ *    code analysis tools. It also performs class diagnostics by compiling all
+ *    of your class property maps, which means that you can be 100% sure that
+ *    all of your maps are valid (compilable) if this tool runs successfully.
+ *
+ *  - We provide a complete, internal API which your subclasses can use to
+ *    interact with the data inside of the JSON container. This allows you to
+ *    easily override the automatic functions or create additional functions
+ *    for your objects. To override core functions, just define a function with
+ *    the exact same name on your object and make it do whatever you want to.
+ *
+ *    Here are some examples of function overriding:
+ *
+ *      ```php
+ *      public function getFoo()
+ *      {
+ *          // try to read property, and handle a special "current_time" value.
+ *          $value = $this->_getProperty('foo');
+ *          if ($value === 'current_time') { return time(); }
+ *          return $value;
+ *      }
+ *      public function setFoo(
+ *          $value)
+ *      {
+ *          // if they try to set value to "md5", use a special value instead.
+ *          if ($value === 'md5') { $value = md5(time()); }
+ *          return $this->_setProperty('foo', $value);
+ *      }
+ *      ```
+ *
+ *  - All mapping/data conversion is done "lazily", on a per-property basis.
+ *    When you access a property, that specific property is mapped/converted to
+ *    the proper type as defined by your class property map. No time or memory
+ *    is wasted converting properties that you never touch.
+ *
+ *  - Strong type-system. The class property map controls the exact types and
+ *    array depths. You can fully trust that the data you get/set will match
+ *    your specifications. Invalid data that mismatches the spec is impossible.
+ *
+ *  - Advanced settings system. Everything is easily configured via PHP class
+ *    constants, which means that your class-settings are stateless (there's no
+ *    need for any special "settings/mapper object" to keep track of settings),
+ *    and that all settings are immutable constants (which means that they are
+ *    reliable and can never mutate at runtime, so that you can fully trust that
+ *    classes will always behave as-defined in their code).
+ *
+ *    If you want to override multiple core settings identically for all of your
+ *    classes, then simply create a subclass of `LazyJsonMapper` and configure
+ *    all of your settings on that, and then derive all of your other classes
+ *    from your re-configured subclass!
+ *
+ *  - The world's most advanced mapper definition system. Your class property
+ *    maps are defined in an easy PHPdoc-style format, and support multilevel
+ *    arrays (such as `int[][]` for "an array of arrays of ints"), relative
+ *    types (so you can map properties to classes/objects that are relative to
+ *    the namespace of the class property map), parent inheritance (all of your
+ *    parent `extends`-hierarchy's maps will be included in your final property
+ *    map) and even multiple inheritance (you can literally "import" an infinite
+ *    number of other maps into your class, which don't come from your own
+ *    parent `extends`-hierarchy).
+ *
+ *  - Inheriting properties from parent classes or importing properties from
+ *    other classes is a zero-cost operation thanks to how efficient our
+ *    property map compiler is. So feel free to import everything you need.
+ *    You can even use this system to create importable classes that just hold
+ *    "collections" of shared properties, which you import into other classes.
+ *
+ *  - The class property maps are compiled a single time per-class at runtime,
+ *    the first time a class is used. The compilation process fully verifies
+ *    and compiles all property definitions, all parent maps, all inherited
+ *    maps, and all maps of all classes you link properties to.
+ *
+ *    If there are any compilation problems due to a badly written map anywhere
+ *    in your hierarchy, you will be shown the exact problem in great detail.
+ *
+ *    In case of success, the compiled and verified maps are all stored in an
+ *    incredibly memory-efficient format in a global cache which is shared by
+ *    your whole PHP runtime, which means that anything in your code or in any
+ *    other libraries which accesses the same classes will all share the cached
+ *    compilations of those classes, for maximum memory efficiency.
+ *
+ *  - You are also able to access JSON properties that haven't been defined in
+ *    the class property map. In that case, they are treated as undefined and
+ *    untyped (`mixed`) and there won't be any automatic type-conversion of such
+ *    properties, but it can still be handy in a pinch.
+ *
+ *  - There are lots of data export/output options for your object's JSON data,
+ *    to get it back out of the object again: As a multi-level array, as nested
+ *    stdClass objects, or as a JSON string representation of your object.
+ *
+ *  - We include a whole assortment of incredibly advanced debugging features:
+ *
+ *    You can run the constructor with `$requireAnalysis` to ensure that all
+ *    of your JSON data is successfully mapped according to your class property
+ *    map, and that you haven't missed defining any properties that exist in the
+ *    data. In case of any problems, the analysis message will give you a full
+ *    list of all problems encountered in your entire JSON data hierarchy.
+ *
+ *    For your class property maps themselves, you can run functions such as
+ *    `printPropertyDescriptions()` to see a complete list of all properties and
+ *    how they are defined. This helps debug your class inheritance and imports
+ *    to visually see what your final class map looks like, and it also helps
+ *    users see all available properties and all of their virtual functions.
+ *
+ *    And for the JSON data, you can use functions such as `printJson()` to get
+ *    a beautiful view of all internal JSON data, which is incredibly helpful
+ *    when you (or your users) need to figure out what's available inside the
+ *    current object instance's data storage.
+ *
+ *  - A fine-grained and logical exception-system which ensures that you can
+ *    always trust the behavior of your objects and can catch problems easily.
+ *    And everything we throw is _always_ based on `LazyJsonMapperException`,
+ *    which means that you can simply catch that single "root" exception
+ *    whenever you don't care about fine-grained differentiation.
+ *
+ *  - Clean and modular code ensures stability and future extensibility.
+ *
+ *  - Deep code documentation explains everything you could ever wonder about.
+ *
+ *  - Lastly, we implement super-efficient object serialization. Everything is
+ *    stored in a tightly packed format which minimizes data size when you need
+ *    to transfer your objects between runtimes.

+
+    /**
+     * Whether we should cache all magic virtual function translations.
+     *
+     * This constant can be overridden in your subclasses to toggle caching.
+     *
+     * The cache stores all of the current runtime's encountered magic/virtual
+     * function name translations, such as `SomeProperty` (via `getSomeProperty`
+     * and `setSomeProperty`, etc) and the fact that it refers to a JSON
+     * property that will be named either `some_property` (if snake style)
+     * or `someProperty` (if camel style).
+     *
+     * Entries are added to the cache one-by-one every time you call a function
+     * on an uncached property name for the first time. The next time you call a
+     * function which accesses the same property name, then there's no need to
+     * analyze the function name again (to figure out what JSON data property it
+     * refers to), since the translation is already cached. It is cached on a
+     * per-property name basis. So a SINGLE cached translation of `SomeProperty`
+     * will be shared by ALL function calls related to that property (such as
+     * all of the core functions; `hasSomeProperty`, `isSomeProperty`,
+     * `getSomeProperty`, `setSomeProperty`, and `unsetSomeProperty`).
+     *
+     * At the cost of a very tiny bit of RAM, this caching greatly speeds up
+     * magic function calls so that they only take about 16% as long as they
+     * would without the cache. However, they're still very fast even without a
+     * cache, and you may be accessing so many different properties that you'd
+     * prefer to avoid a cache for memory reasons (if you prefer lower memory
+     * needs over pure speed). The choice is yours.
+     *
+     * To calculate the memory needs of your own project's virtual function
+     * cache, you simply need to know that an average cache entry uses ~248.6
+     * bytes of RAM on PHP 7 and ~510.4 bytes on PHP 5. Note that the size per
+     * name translation is small enough to be measured in BYTES (NOT kilobytes)!
+     *
+     * Those averages were calculated from a huge sample-size of 10000 function
+     * names, and are very accurate for real-world JSON data.
+     *
+     * To calculate your own cache memory size, think about how many different
+     * JSON properties you'll need to access in your project. Most normal
+     * projects would probably only access at most 100 different property names
+     * (such as `getComments`, `setTime`, etc), since you most likely won't
+     * access every property in the JSON data. So only count the properties
+     * you'll access. And also remember that identical property names used
+     * across different classes, and all the different functions for accessing
+     * the same property, will still only require a SINGLE global cache entry
+     * per property name.
+     *
+     * The storage needs for 100 different property name translations would be
+     * as follows. As you can see, the cache is very memory-efficient:
+     *
+     * - PHP 7: 100x ~248.6 bytes = 24 860 bytes (~24.9 kilobytes).
+     * - PHP 5: 100x ~510.4 bytes = 51 040 bytes (~51.1 kilobytes).
+     *
+     * (If you're still using PHP 5, you should really consider upgrading to
+     * PHP 7 with its better memory efficiency and its much faster engine!)
+     *
+     * It is highly recommended to use caching, and it is enabled by default
+     * unless you override the constant in your class, as follows:
+     *
+     *   ```php
+     *   class MyUncachedLazyJsonMapper extends LazyJsonMapper
+     *   {
+     *       const USE_MAGIC_LOOKUP_CACHE = false;
+     *   }
+     *   ```
+     *

+     * Tells us how to map JSON properties to internal PHP types or objects.
+     *
+     * This constant can be overridden in your subclasses, to add custom JSON
+     * mapping definitions to your class. It is recommended to always do so.
+     *
+     * The value must be an array of key-value pairs, where the key is the name
+     * of a JSON property and the value is a string with the definition for that
+     * specific property in PHPdoc-style. We will then perform automatic, strict
+     * lazy-conversion of the value to the target type whenever you access that
+     * property. (However, be aware that we always allow `NULL` values in any
+     * property, and will never enforce/convert those to the target type.)
+     *
+     * The following built-in types are supported: `bool`, `int`, `float`,
+     * `string`. The JSON data will be type-converted to match that type.
+     *
+     * Note that if the type is set to `mixed` or an empty string `""` instead,
+     * then the property will allow any of the built-in types (`bool`, `int`,
+     * `float`, `string`, `NULL` (as always) and multi-level arrays of any of
+     * those types). There simply won't be any "forced" type-conversion to any
+     * specific basic type for that property since you haven't defined any
+     * strict type.
+     *
+     * Setting up untyped properties is still useful even if you don't know its
+     * type, since defining the property in the class map ensures that you can
+     * always get/set/access/use that property even if it's unavailable in the
+     * current object instance's internal JSON data.
+     *
+     * You can also map values to objects. In the case of objects (classes), the
+     * classes MUST inherit from `LazyJsonMapper` so they support all necessary
+     * mapping features. To assign a class to a property, you can either write a
+     * FULL (global) class path starting with a leading backslash `\`, such as
+     * `\Foo\Bar\Baz`. Alternatively, you can use a RELATIVE path related to the
+     * namespace of the CURRENT MAP'S class, such as `Bar\Baz` (if your current
+     * class is `\Foo\Whatever`, then it'd be interpreted as `\Foo\Bar\Baz`).
+     * Anything that DOESN'T start with a leading backslash is interpreted as a
+     * relative class path! Just be aware that your class `use`-statements are
+     * completely ignored since PHP has no mechanism to let us detect those.
+     *
+     * It's also possible to map properties to the core `LazyJsonMapper` object
+     * if you simply want an object-oriented container for its data without
+     * writing a custom class. You can do that by defining the property type as
+     * either `\LazyJsonMapper\LazyJsonMapper`, or as `LazyJsonMapper` (which is
+     * a special shortcut that ALWAYS resolves to the core class). But it's
+     * always best to write a proper class, so that its properties are reliable.
+     *
+     * Lastly, you can map "arrays of TYPE" as well. Simply add one or more `[]`
+     * brackets to the end of the type. For example, `int[]` means "array of
+     * ints", and `\Foo[][][]` means "array of arrays of arrays of `\Foo`
+     * objects". It may be easier to understand those mentally if you read them
+     * backwards and say the words "array of" every time you see a `[]` bracket.
+     * (Note: You can also use the array notation with `mixed[][]`, which would
+     * then strictly define that the value MUST be mixed data at an exact depth
+     * of 2 arrays, and that no further arrays are allowed deeper than that.)
+     *
+     * The assigned types and array-depths are STRICTLY validated. That's an
+     * integral part of the `LazyJsonMapper` container, since it guarantees your
+     * class property map interface will be strictly followed, and that you can
+     * fully TRUST the data you're interacting with. If your map says that the
+     * array data is at depth 8 and consists of `YourObject` objects, then we'll
+     * make sure the data is indeed at depth 8 and their value type is correct!
+     *
+     * That goes for arrays too. If you define an `int[]` array of ints, then
+     * we'll ensure that the array has sequential numeric keys starting at 0 and
+     * going up without any gaps, exactly as a JSON array is supposed to be. And
+     * if you define an object `YourObject`, then we'll ensure that the input
+     * JSON data consists of an array with associative keys there (which is used
+     * as the object properties), exactly as a JSON object is supposed to be.
+     *
+     * In other words, you can TOTALLY trust your data if you've assigned types!
+     *
+     * Example property map:
+     *
+     * ```php
+     * const JSON_PROPERTY_MAP = [
+     *     'some_string'              => 'string',
+     *     'an_object'                => '\YourProject\YourObject',
+     *     'array_of_numbers'         => 'int[]',
+     *     'array_of_objects'         => 'RelativeObject[]',
+     *     'untyped_value'            => '', // shorthand for 'mixed' below:
+     *     'another_untyped_value'    => 'mixed', // allows multilevel arrays
+     *     'deep_arr_of_arrs_of_int'  => 'int[][]',
+     *     'array_of_mixed'           => 'mixed[]', // enforces 1-level depth
+     *     'array_of_generic_objects' => 'LazyJsonMapper[]',
+     * ];
+     * ```
+     *
+     * Also note that we automatically inherit all of the class maps from all
+     * parents higher up in your object-inheritance chain. In case of a property
+     * name clash, the deepest child class definition of it takes precedence.
+     *
+     * It is also worth knowing that we support a special "multiple inheritance"
+     * instruction which allows you to "import the map" from one or more other
+     * classes. The imported maps will be merged onto your current class, as if
+     * the entire hierarchy of properties from the target class (including the
+     * target class' inherited parents and own imports) had been "pasted inside"
+     * your class' property map at that point. And you don't have to worry
+     * about carefully writing your inheritance relationships, because we have
+     * full protection against circular references (when two objects try to
+     * import each other) and will safely detect that issue at runtime whenever
+     * we try to compile the maps of either of those bad classes with their
+     * badly written imports.
+     *
+     * The instruction for importing other maps is very simple: You just have to
+     * add an unkeyed array element with a reference to the other class. The
+     * other class must simply refer to the relative or full path of the class,
+     * followed by `::class`.
+     *
+     * Example of importing one or more maps from other classes:
+     *
+     * ```php
+     * const JSON_PROPERTY_MAP = [
+     *     'my_own_prop'                     => 'string',
+     *     OtherClass::class,                // relative class path
+     *     'redefined_prop'                  => float,
+     *     \OtherNamespace\SomeClass::class, // full class path
+     * ];
+     * ```
+     *
+     * The imports are resolved in the exact order they're listed in the array.
+     * Any property name clashes will always choose the version from the latest
+     * statement in the list. So in this example, our class would first inherit
+     * all of its own parent (`extends`) class maps. Then it would add/overwrite
+     * `my_own_prop`. Then it imports everything from `OtherClass` (and its
+     * parents/imports). Then it adds/overwrites `redefined_prop` (useful if you
+     * want to re-define some property that was inherited from the other class).
+     * And lastly, it imports everything from `\OtherNamespace\SomeClass` (and
+     * its parents/imports). As long as there are no circular references,
+     * everything will compile successfully and you will end up with a very
+     * advanced final map! And any other class which later inherits from
+     * (extends) or imports YOUR class will inherit the same advanced map from
+     * you! This is REAL "multiple inheritance"! ;-)
+     *
+     * Also note that "relative class path" properties are properly inherited as
+     * pointing to whatever was relative to the original inherited/imported
+     * class where the property was defined. You don't have to worry about that.
+     *
+     * The only thing you should keep in mind is that we ONLY import the maps.
+     * We do NOT import any functions from the imported classes (such as its
+     * overridden functions), since there's no way for us to affect how PHP
+     * resolves function calls to "copy" functions from one class to another. If
+     * you need their functions, then you should simply `extends` from the class
+     * to get true PHP inheritance instead of only importing its map. Or you
+     * could just simply put your functions in PHP Traits and Interfaces so
+     * that they can be re-used by various classes without needing inheritance!
+     *
+     * Lastly, here's an important general note about imports and inheritance:
+     * You DON'T have to worry about "increased memory usage" when importing or
+     * inheriting tons of other classes. The runtime "map compiler" is extremely
+     * efficient and re-uses the already-compiled properties inherited from its
+     * parents/imports, meaning that property inheritance is a ZERO-COST memory
+     * operation! In fact, re-definitions are also zero-cost as long as your
+     * class re-defines a property to the exact same type that it had already
+     * inherited/imported. Such as `Base: foo:string, Child: foo:string`. In
+     * that case, we detect that the definitions are identical and just re-use
+     * the compiled property from `Base` instead. It's only when a class adds
+     * NEW/MODIFIED properties that memory usage increases a little bit! In
+     * other words, inheritance/imports are a very good thing, and are always a
+     * better idea than manually writing similar lists of properties in various
+     * unrelated (not extending each other) classes. In fact, if you have a
+     * situation where many classes need similar properties, then it's a GREAT
+     * idea to create special re-usable "property collection" classes and then
+     * simply importing THOSE into ALL of the different classes that need those
+     * sets of properties! You can even use that technique to get around PHP's
+     * `use`-statement limitations (simply place a "property collection" class
+     * container in the namespace that had all of your `use`-classes, and define
+     * its properties via easy, relative paths there, and then simply make your
+     * other classes import THAT container to get all of its properties).
+     *
+     * As you can see, the mapping and inheritance system is extremely powerful!
+     *
+     * Note that the property maps are analyzed and compiled at runtime, the
+     * first time we encounter each class. After compilation, the compiled maps
+     * become immutable (cannot be modified). So there's no point trying to
+     * modify this variable at runtime. That's also partially the reason why
+     * this is defined through a constant, since they prevent you from modifying
+     * the array at runtime and you believing that it would update your map. The
+     * compiled maps are immutable at runtime for performance & safety reasons!
+     *
+     * Have fun!

+     *
+     * This is where you can perform your custom subclass initialization, since
+     * you are unable to override the main constructor.
+     *
+     * We automatically run this function at the end of the normal constructor,
+     * as well as every time that you manually use `assignObjectData()` to
+     * replace the object's data. (When new data is assigned, you should treat
+     * yourself as a new object, which is why `_init()` will run again.)
+     *
+     * `WARNING:` Please RESIST the urge to touch ANY of the internal JSON data
+     * during this initialization. All data will always be automatically
+     * validated during actual retrieval and setting, so you can always trust
+     * that the final types WILL match your class property map definitions.
+     *
+     * Remember that any extra work you do in `_init()` will run EVERY time an
+     * instance of your object is created, even when those objects live within a
+     * main object. So if your function is heavy, it will slow down operation of
+     * the class; and your parsing of the properties would be counter-productive
+     * against the goal of "lazy parsing" of JSON data on a when-accessed basis!
+     *
+     * Instead, it's preferable to just override specific property getter and
+     * setter functions, to make your class return different default values if a
+     * certain internal data field is missing an expected value. But in general,
+     * your ultimate USER CODE should be responsible for most of THAT checking,
+     * by simply looking for `NULL` (denoting a missing value in the JSON data
+     * container), and then deciding what to do with that in your final project.
+     *
+     * Lastly, there are a few rules that MUST be followed by your `_init()`:
+     *
+     *  1. As explained above, but worth repeating again: Your `LazyJsonMapper`
+     *  classes are supposed to be LIGHT-weight "JSON data containers". So
+     *  please DO NOT treat this as a "standard class constructor". The more
+     *  work you do in `_init()`, the slower your object creation is. And since
+     *  your object is a JSON container which is automatically created from
+     *  data, you can expect LOTS of instances of your class to be created
+     *  during normal runtime! That's also why your `_init()` function does not
+     *  get any parameters! That is to discourage misuse as a normal class.
+     *
+     *  Also remember that you may not even need `_init()`, since you can simply
+     *  give your properties default values instead of using `_init()`, such as
+     *  by writing `public $myproperty = true;`. All instances of that object
+     *  would then start with that value set to `TRUE` by default.
+     *
+     *  2. You can ONLY throw `LazyUserException`. All other exceptions will be
+     *  blocked and turned into a generic `LazyUserException`. This is done to
+     *  ensure that your custom init function cannot break the contract that the
+     *  `LazyJsonMapper` constructor guarantees in its listed exceptions.
+     *
+     *  (That's also the reason why all built-in functions except `_init()` are
+     *  marked `final`: So that subclasses cannot break the `LazyJsonMapper`
+     *  API/interface contract. If something IS a `LazyJsonMapper`, it MUST
+     *  behave as a `LazyJsonMapper`, and the `final` functions guarantee that!)
+     *
+     *  3. If your class extends from `LazyJsonMapper`, then there's no need to
+     *  call `parent::_init()` (since our core `_init()` does nothing). But if
+     *  you extend from ANY OTHER CLASS, you MUST call your parent's init BEFORE
+     *  doing any work, just to guarantee that your WHOLE parent-class hierarchy
+     *  is fully initialized first.
+     *
+     *  4. Understand and accept the fact that your personal class properties
+     *  will NOT be serialized if you serialize an object. Only the JSON data
+     *  array will be kept. The `_init()` function will be called again when you
+     *  unserialize the object data, as if your object had just been created for
+     *  the first time. This is done to save space and to discourage misuse
+     *  of your `LazyJsonMapper` containers.
+     *
+     *  Remember that your classes are supposed to be lightweight JSON data
+     *  containers, which give you a strongly typed, automatic, object-oriented
+     *  interface to your data. Classes "with advanced constructors and tons of
+     *  properties" are NOT suitable as JSON containers and belong ELSEWHERE in
+     *  the rest of your project!
+     *
+     * @throws LazyUserException If there is any fatal error which prevents
+     *                           initialization. This stops object construction
+     *                           if this is the initial construction. However,
+     *                           it doesn't affect data-assignment if you throw
+     *                           during a later `assignObjectData()` call.

+     * It is recommended that you save the result if you intend to re-use it
+     * multiple times, since each call to this function will need to perform
+     * copying and data conversion from our internal object representation.
+     *
+     * Note that the conversion process will recursively validate and convert
+     * all properties in the entire internal data hierarchy. You can trust that
+     * the returned result will be perfectly accurate and follow your class map
+     * property type-rules. This does however mean that the data may not be the
+     * same as the input array you gave to `__construct()`. For example, if your
+     * input contained an array `["1", "2"]` and your type definition map says
+     * that you want `int` for that property, then you'd get `[1, 2]` as output.
+     *
+     * The conversion is always done on a temporary COPY of the internal data,
+     * which means that you're welcome to run this function as much as you want
+     * without causing your object to grow from resolving all its sub-objects.
+     *

+     * do ANYTHING with it, without risk of affecting any of OUR internal data.

+     * `WARNING:` If you intend to use the result to `json_encode()` a new JSON
+     * object then please DON'T do that. Look at `asJson()` instead, which gives
+     * you full control over all JSON output parameters and properly handles the
+     * conversion in all scenarios, without you needing to do any manual work.

+     * Internally runs `asJson()`.
+     *
+     * `WARNING:` It's **dangerous** to rely on the automatic string conversion,
+     * since PHP doesn't allow this handler to throw any error/exceptions (if we
+     * do, PHP would die with a Fatal Error). So we cannot notify about errors.
+     *
+     * Therefore, any warnings and exceptions will silently be placed directly
+     * in the string output instead, enclosed in `<>` brackets to guarantee that
+     * they won't be interpreted as valid JSON.
+     *
+     * Smart programmers will instead call `$item->asJson()` manually. It is
+     * only a few more characters, and it guarantees that you can catch
+     * conversion errors and react to them appropriately.
+     *
+     * There is only ONE scenario where `__toString()` is reliable: That's if
+     * your JSON data was constructed with the `$requireAnalysis` constructor
+     * argument, which recursively ensures that all data type-conversions and
+     * all nested sub-object constructions are successful before your object is
+     * allowed to be created. Furthermore, you must not have manipulated
+     * anything via "direct property access by reference" AFTER that (as
+     * explained in `__get()`), so that you're sure that all of your internal
+     * data is truly valid.
+     *
+     * But that is all moot anyway, because always using the debug-only option
+     * `$requireAnalysis` defeats the purpose of memory-efficient lazy-loading
+     * and slows down the creation of all of your class instances. Don't do it.
+     *
+     * In short: `__toString()` is here as a nice bonus for completeness sake,
+     * but you should never use it in production. Just use `asJson()` instead!

+     * Analyze the entire object and check for undefined or bad JSON properties.
+     *
+     * This lets you analyze the object data & map to look for the following:
+     *
+     *  1. Undefined JSON properties that need to be defined in your classes
+     *  so that their existence becomes permanent and therefore safer to use
+     *  (since defined properties are always retrievable even if they don't
+     *  exist in the current object instance's data). And actually defining
+     *  the properties is also the ONLY way that you can enforce a specific
+     *  data-type, since undefined properties default to untyped (`mixed`).
+     *
+     *  2. Bad class map definitions that don't match the actual JSON data.
+     *  It does this by checking all of the encountered classes within the JSON
+     *  data to ensure that they construct successfully (which they ALWAYS
+     *  will, unless the user has overridden `_init()` and throws from it), as
+     *  well as verifying that all basic PHP type coercions work, and that the
+     *  data is formatted as-described in the definition (such as having the
+     *  correct array-depth, or data defined as objects actually being objects).
+     *
+     * The scan is performed by looking at EVERY item in the object's internal
+     * JSON data array, and checking for a corresponding class map definition
+     * (if nothing exists, it's treated as "missing from the class map"), and
+     * then attempting conversion to its specified type (if that fails, it's
+     * treated as "bad class map definition"). All undefined values (which lack
+     * any class map definition) are ALSO validated as if they were `mixed`,
+     * to ensure that NOTHING can contain illegal values.
+     *
+     * If a recursive scan is requested, then all sub-objects (`LazyJsonMapper`
+     * data containers) will ALSO recursively perform the same analysis on their
+     * own internal data, so that the whole JSON data tree is recursively
+     * verified. Their analysis results will be merged with our return value.
+     *
+     * Note that calling this function will cause the WHOLE object tree to be
+     * constructed and ALL of its mapped properties to be converted/parsed to
+     * verify the class map, which takes some time and permanently increases the
+     * object's memory usage (since conversion causes any internal sub-objects
+     * to be stored as actual objects instead of merely as plain sub-arrays)!
+     *
+     * Therefore, you should ONLY use this function when necessary: When you
+     * need advanced and powerful debugging of your class maps!
+     *
+     * @param bool $recursiveScan Whether to also verify missing/bad properties

+     * `_getProperty()` call again, and B) you have to explicitly bind the
+     * returned value by reference to actually risk affecting the internal
+     * data, as explained below.
+     *
+     * Method 1 (recommended for almost 100% of all usages, safest):
+     *
+     *  ```php
+     *  $val = $this->_getProperty('foo'); // Copy-on-write assignment to $val.
+     *  $val = 'bar'; // Does NOT modify the internal data "foo" property.
+     *  ```
+     *
+     * Method 2 (dangerous, and this example even contains an intentional bug):
+     *
+     *  ```php
+     *  $val = &$this->_getProperty('foo'); // Reference assignment to $val.
+     *  $val = 'bar'; // Direct link, thus modifies the internal "foo" property.
+     *  ```
+     *
+     * `SERIOUS WARNING:` If you use Method 2, do NOT use the code above. It was
+     * just explained that way to demonstrate a SERIOUS MISTAKE. If you assign
+     * by reference, you obviously intend to link directly to internal data. But
+     * the code above fails if no internal data for that property exists yet. In
+     * that case, the code above will write to a temporary `NULL` variable which
+     * is not linked at all to the object. Instead, you MUST ALWAYS use
+     * `$createMissingValue = true` if you want TRUSTABLE data references.
+     *
+     * Method 2 (the CORRECT way of writing it):
+     *
+     *  ```php
+     *  $val = &$this->_getProperty('foo', true);
+     *  $val = 'bar';
+     *  ```
+     *
+     * That FIXED code will create the property and put `NULL` in it if it's
+     * missing from the internal data, and then returns the reference to the
+     * created internal data entry. It's the ONLY way to ensure REAL references.
+     *
+     * Note that there is ZERO PERFORMANCE BENEFIT of assigning our return-value
+     * by reference. ONLY use references if you have an ADVANCED reason for it!
+     * Internally, PHP treats both assignment types identically until the moment
+     * you try to write to/modify the contents of the variable. So if you are
+     * only reading, which is most of the time, then there's no reason to use a
+     * reference. And never forget that modifying via direct reference lets you
+     * write invalid data (which won't be detected until a `_getProperty()`
+     * call attempts to read that bad data again), as mentioned earlier.
+     *
+     * There is one final warning: If YOU have a "return-by-reference" function,
+     * then you will AUTOMATICALLY return a direct link to the inner data if you
+     * use us directly in your return statement. Here's an example of that:
+     *
+     *  ```php
+     *  public function &myFunction() { // <-- Note the "&" return-by-ref here!
+     *      // returns reference to real internal data OR temp var (badly coded)
+     *      return $this->_getProperty('foo'); // <-- VERY DANGEROUS BUG!
+     *
+     *      // returns reference to real internal data (correctly coded)
+     *      return $this->_getProperty('foo', true); // <-- CORRECT!
+     *
+     *      // you can also intentionally break the link to the internal data,
+     *      // by putting it in a copy-on-write variable and returning THAT:
+     *      $copyOnWrite = $this->_getProperty('foo'); // copy-on-write (no ref)
+     *      return $copyOnWrite; // ref to $copyOnWrite but not to real internal
+     *  }
+     *  ```
+     *
+     * @param string $propName           The property name.
+     * @param bool   $createMissingValue If `TRUE` then we will create missing
+     *                                   internal object data entries (for
+     *                                   class-defined properties) and store a
+     *                                   `NULL` in them. This will "pollute" the
+     *                                   internal data with default `NULL`s for
+     *                                   every missing property that you attempt
+     *                                   to retrieve, but it's totally NECESSARY
+     *                                   if you intend to use the return-value
+     *                                   by-reference, since we MUST store the

+     *                                   actual object's internal data storage!

+     * __GET is invoked when reading data from inaccessible properties.
+     *
+     * This magic handler takes care of "virtual property" access to the
+     * object's JSON data properties.
+     *
+     * `WARNING:` Note that the `__get()` "virtual property" handling creates
+     * `NULL` values in any missing (but valid in class-map) properties that you
+     * try to access! That is NECESSARY because PHP EXPECTS the `__get()` return
+     * value to be a REFERENCE to real internal data, so we MUST create a value
+     * if no value exists, so that we can link PHP to a true reference to the
+     * internal data. Obviously we can't link to something that doesn't exist,
+     * which is why we MUST create `NULL` values. Unfortunately that means that
+     * "virtual property access" will lead to increased memory usage and worse
+     * JSON output (due to all the added values) if you want to export the
+     * internal data as JSON later.
+     *
+     * The recommended access method, `$obj->getFoo()` ("virtual functions")
+     * doesn't have that problem. It ONLY happens when you decide to use
+     * `$obj->foo` for "direct virtual property" access.
+     *
+     * There are several other quirks with "direct virtual properties", due to
+     * how PHP works. If you don't write your code carefully, you may cause
+     * serious issues with performance or unexpected results.
+     *
+     * All of the important quirks are as follows:
+     *
+     *  1. The aforementioned necessary `NULL` value insertion increases memory
+     *  usage and may lead to unexpected problems if you convert back to JSON,
+     *  such as if the server does not expect those values to exist with `NULL`.
+     *
+     *  2. Anytime you use the array `[]` access operator on the outer property
+     *  name, PHP will trigger a `__get()` call, which of course does its whole
+     *  data-validation again. The following would therefore be EXTREMELY SLOW,
+     *  and possibly even DANGEROUS (since you're manipulating the array while
+     *  looping over its keys while constantly triggering `__get()` re-parsing):
+     *
+     *    ```php
+     *    foreach ($obj->something as $k => $v) {
+     *        // Every assignment here will do __get('something') which parses
+     *        // the array over and over again before each element is modified:
+     *        $obj->something[$k] = 'foo';
+     *    }
+     *    ```
+     *
+     *  The proper way to solve THAT is to either save a reference to
+     *  `$obj->something` as follows:
+     *
+     *    ```php
+     *    $ref = &$obj->something; // Calls __get('something') a single time.
+     *    foreach ($ref as $k => $v) {
+     *        $ref[$k] = 'foo'; // Changes array directly via stored reference.
+     *    }
+     *    ```
+     *
+     *  Or to loop through the input values as follows:
+     *
+     *    ```php
+     *    foreach ($obj->something as &$v) { // Note the "&" symbol.
+     *        $v = 'foo'; // Changes array value directly via reference.
+     *    }
+     *    ```
+     *
+     *  3. Anytime you use a reference, there will be NO DATA VALIDATION of the
+     *  new value you are inputting. It will not be checked again UNTIL the next
+     *  internal `_getProperty()` call for that property (ie. by the next
+     *  `__get()`) so you may therefore unintentionally insert bad data that
+     *  doesn't match the class definition map:
+     *
+     *    ```php
+     *    // Saving a reference to internal data and then changing that variable
+     *    // will directly edit the value without letting us validate it:
+     *
+     *    $ref = &$obj->some_string; // Make "$ref" into a reference to data.
+     *    $ref = new InvalidObject(); // Writes a bad value directly to memory.
+     *    var_dump($obj->some_string); // Throws error because of bad data.
+     *
+     *    // The same is true about array access. In this case, PHP does
+     *    // __get('some_int_array') and finds an array, and then it directly
+     *    // manipulates that array's memory without letting us validate it:
+     *
+     *    $obj->some_int_array[] = new InvalidObject();
+     *    $obj->some_int_array[15] = new InvalidObject();
+     *    var_dump($obj->some_int_array); // Throws error because of bad data.
+     *    ```
+     *
+     *  4. You can always trust that `__set()` assignments WILL be validated.
+     *  But a `__set()` ONLY happens when you assign with the equals operator
+     *  (`=`) to a pure property name WITHOUT any array access (`[]`) operators.
+     *
+     *    ```php
+     *    $obj->some_property = '123'; // Calls __set() and validates new value.
+     *    $obj->an_array[] = '123' // Calls __get() and won't validate changes.
+     *    ```
+     *
+     * These quirks of "virtual direct property access" are quite easy to deal
+     * with when you know about them, since almost all of them are about array
+     * access, and the rest are about intentional misuse by binding directly to
+     * references. Just avoid making those mistakes.
+     *
+     * However, in general, you should REALLY be using the "virtual function"
+     * access method instead, which allows you to do great things such as
+     * overriding certain class property-functions (ie `getSomething()`) with
+     * your own custom behaviors, so that you can do extra validation, get/set
+     * value transformations, and other fantastic things!
+     *
+     * It is possible (and recommended) to disable virtual properties via the
+     * `ALLOW_VIRTUAL_PROPERTIES` class constant. The feature is only enabled by
+     * default because it helps people easily migrate from legacy projects.

+     * PHP doesn't allow these special operators in function names, so we cannot
+     * legally generate such function names. Instead, we'll encode the operators
+     * with a sequence that will never appear in our normal algorithm's output.
+     *
+     * For example, if the user has a property named `en-US`, our special
+     * operator translation will give it a function name of `getEn_x2D_US()`
+     * to safely encode the arithmetic minus symbol.
+     *
+     * This encoding scheme was deliberately chosen thanks to the fact that it
+     * will never conflict with anything else that's legitimately generated by
+     * our algorithm. Because if the user has a property that's _actually_ named
+     * `en_x2D_US`, then that one would be encoded as `getEnX2D_US()` (by the
+     * main `PropertyTranslation` algorithm), which is obviously not the same
+     * thing and will never confuse our parser in decoding later. And if they
+     * sent us `en__x2D_US`, it would be encoded as `getEn_X2D_US()`, which is
+     * yet again different (the `X` is uppercase in that situation too).
+     *
+     * Therefore, our special encoding of `_x[HEX]_` will never be generated by
+     * any legitimate user property names, even if those names do contain that
+     * sequence on-disk. They'll all be encoded to something else. The only
+     * thing that can put a lowercase `x` in this particular arrangement is our
+     * own operator symbol translator here.
+     *
+     * As for why we need that long sequence instead of something shorter, it's
+     * unfortunately the only way that we can guarantee uniqueness. It relies on
+     * the principle that `_x` in the user's own properties would ALWAYS be
+     * encoded as `X`. Most programmers are familiar with hex codes and will
+     * recognize the sequences we've chosen: `getEn_x2D_US()`, where `x` stands
+     * for "hex", and `2D` is the hex character value for the minus symbol.
+     *
+     * This particular encoding also allows us to easily encode future illegal
+     * characters of any length (even multiple bytes such as `_xFFFF_` if ever
+     * necessary) without needing to change the encoding scheme again.

+     *
+     * That extra protection does however also mean that your runtime's initial

+        // to compile. We obviously want to figure that out for the user RIGHT
+        // NOW so that they don't run into issues later when trying to access
+        // such a property someday (which would THEN trigger its map compilation
+        // and throw a compiler failure deep into their runtime environment when
+        // they least expected it). The truth is that normal people will
+        // sometimes write bad classes, and then point properties at those bad
+        // classes. And without us proactively pre-compiling all classes pointed
+        // to by their properties, they would NEVER know about the problem until
+        // someday later when their program suddenly accesses that bad property
+        //
+        // So we SHOULD analyze everything for the user's safety. But... we

+        // In fact, we cannot even compile them afterwards EITHER, UNLESS we are
+        // the ABSOLUTE ROOT COMPILE-CALL which STARTED the current compilation
+        // process. Only the root function call is allowed to resolve PROPERTY
+        // references to other classes and ensure that THOSE maps are
+        // successfully are compiled too. Otherwise we'd run into circular
+        // compilation issues where properties fail to compile because they may
+        // be pointing at things which are not compiled yet (such as a class
+        // containing a property that points at itself, or "A" having a property
+        // that points to class "B" which has a property that points to class
+        // "C" which has a property that points back at class "A" and therefore
+        // would cause a circular reference if we'd tried to compile those
+        // property-classes instantly as-they're encountered). We must therefore
+        // defer property-class compilation until ALL core classes in the
+        // current inheritance/import chain are resolved. THEN it's safe to
+        // begin compiling any other encountered classes from the properties...
+        //
+        // The solution is "simple": Build a list of the class-paths of all
+        // encountered UNCOMPILED property classes within our own map tree and
+        // within any imports (which are done via recursive compile-calls). To
+        // handle imports, we simply ensure that our compile-function (this one)
+        // lets the parent retrieve our list of "encountered uncompiled classes
+        // from properties" so that we'll let it bubble up all the way to the
+        // root class/call that began the whole compile-chain. And then just let
+        // that root-level call resolve ALL uncompiled properties from the
+        // ENTIRE tree by simply compiling the list of property-classes one by
+        // one if they're still missing. That way, we'll get full protection
+        // against uncompilable class-properties ANYWHERE in our tree, and we'll
+        // do it at a totally safe time (at the end of the main compilation call
+        // that kicked everything off)!
+        //
+        // NOTE: As an optimization, to avoid constant array-writes and the
+        // creation of huge and rapidly growing "encountered classes" arrays, we
+        // will attempt to ONLY track the encountered classes that are MISSING
+        // from the cache (not yet compiled). And this list will ALSO be checked
+        // one more time at the end, to truly clear everything that's already
+        // done. That's intended to make the list as light-weight as possible
+        // so that our parent-compiler doesn't have to do heavy lifting.
+        //
+        // NOTE: The fact is that most classes that properties point to will
+        // already be pre-compiled, or at least large parts of their
+        // inheritance/import hierarchy will already be compiled, so this
+        // recursive "property-class" compilation isn't very heavy at all. It's

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team. All complaints will be reviewed and investigated and will result in a response that is deemed necessary and appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.
+

+
+The following is a set of guidelines for contributing to the Instagram API, which is hosted in the [Instagram API repository](https://github.com/mgp25/Instagram-API) on GitHub.
+
+These are just guidelines, not rules. Use your best judgment, and feel free to propose changes to this document in a pull request.

+## What should I know before I get started?
+
+### Code of Conduct
+
+This project adheres to the Contributor Covenant [code of conduct](CODE_OF_CONDUCT.md).
+By participating, you are expected to uphold this code.
+Please report any unacceptable behavior.
+
+## Basic rules
+
+Important! Your contributions must follow all of these rules for a consistent and bug-free project.
+
+This is a document which, among other things, describes PSR-4 class autoloading, clean commits, how to handle/document exceptions, how to structure function arguments, naming clear variables, always adding/updating PHPdoc blocks in all affected functions, and how to verify that your changes don't _break everything_ when performing big changes to existing functions or adding brand new functions and classes.
+
+
+### Git Setup
+
+If you are using a Linux/Mac/Unix system, you **MUST** install our git-hook in your local repository. It will help prevent you from accidentally committing badly formatted code. Please run the following command in the project's root folder (the folder which has files like `README.md` etc), to install the hook in your repository:
+
+```
+ln -fs "../../.pre-commit.hook" .git/hooks/pre-commit
+```
+
+
+### Codestyle Command
+
+Before committing any work, you **MUST** always run the codestyle fixer command in the root folder of the repository:
+
+```
+composer codestyle
+```
+
+That command will automatically fix all codestyle issues as well as generate various documentation, such as the class docs for all of the Responses and Model items.
+
+
+### Available Tasks
+
+Please visit our [Project Task Tracker](https://github.com/mgp25/Instagram-API/projects), where contributors can look at the list of available work. High-quality code contributions are greatly appreciated.
+
+
+### Commits
+
+- You **MUST** try to **separate** work into smaller commits. So if you `"changed Utils.php to fix getSeconds and changed Request.php to fix Request()"`, then make **TWO SEPARATE COMMITS**, so that we can easily find your changes in the project history, and can easily revert any individual broken changes without losing tons of other code too! So remember: 1 commit per task. :smile:
+
+- Use the detailed description field of your commit, to document why you did certain changes if it's not an obvious change (such as a typo fix). Your description gets added to the history of the project so that we can know what you were thinking, if we need to check the change again later.
+
+- **Name** your single-file commits `"AffectedClassName: Change description"` and keep the total length of the summary line at 50 characters or less in total (the Git/GitHub standard).
+
+- If your change NEEDS to affect multiple files, then it is SOMETIMES okay to leave out the classname part from the summary, but in that case you _must_ write a very clear and descriptive summary to explain it. _But_ usually you _should_ still include the classname even for multi-file edits. For example, renaming a function in Utils and having to change the name of it in other files is still a `"Utils: Renamed bleh() to bloop()"` commit.
+
+Examples of BAD commit summaries:
+
+```
+Edit something
+Fix this
+Utils+request changes
+```
+
+Examples of GOOD commit summaries:
+
+```
+Utils: Fix formatting of getSeconds
+Request: Send cropping information
+Changed all number_format() to round() everywhere
+Response: Parse timestamps as floats
+```
+
+
+### Modifying anything in the existing code
+
+- If you want to change a public API function's parameters (particularly in `src/Instagram.php`), think EXTREMELY hard about NOT doing it. And if you absolutely MUST do it (such as adding an important new parameter), then you MUST add it in a BACKWARDS-COMPATIBLE WAY, by adding it as the LAST parameter of the argument list AND providing a sensible DEFAULT VALUE for it so that people's CURRENT projects based on this library continue working and DON'T BREAK due to your function definition changes!
+
+- Do NOT look at your changes in isolation. Look at the BIG PICTURE of what your change now does to the REST of the codebase.
+
+- For example, if you change the returned variable type from a function (such as from an `"int"` to a `"string"`), then you MUST update the function's PHPdoc block to document the new return value (with `@return string`), and you MUST also slowly and carefully check ALL OTHER CODE that relied on the OLD behavior of that function. There's a command-line tool called "grep" (or an even better one especially made for programmers, called ["ag" aka "the silver searcher"](https://github.com/ggreer/the_silver_searcher)) to search for text in files. USE IT to check ALL other code locations that called your modified function, and make sure that you didn't break ANY of them AT ALL!
+
+- In fact, ANY TIME that you change a function's ARGUMENTS, RETURN VALUE or THROWN EXCEPTIONS (new/deleted ones), then you MUST update the function's PHPdoc block to match the new truth. And you MUST check ALL other functions that CALL your function, and update those too. For example let's say they DON'T handle a new exception you're now throwing, in which case you MUST now update THEIR `@throws` documentation to document the fact that THEY now let yet another exception bubble up. And then you MUST search for the functions that called THOSE updated functions and update THEIR documentation TOO, all the way until you've reached the top and have FULLY documented what exceptions are being thrown in the whole chain of function calls.
+
+- You MUST ALWAYS update the PHPdoc blocks EVERYWHERE that's affected by your changes (whenever you've changed a functions ARGUMENTS or RETURN type or what it THROWS (any new/deleted exceptions)), because imagine if we NEVER update the blocks EVERYWHERE that's affected by your change. We would then have something like `/** @param $a, $b, $c */ function foo ($x)` and sudden, critical exceptions that aren't getting handled and thus KILL the program.
+
+Here's a checklist for what you MUST do to ENSURE totally correct documentation EVERY TIME that you make a CHANGE to a function's ARGUMENTS or RETURN TYPE or EXCEPTIONS of an existing function, OR when you introduce a NEW function whose use is being added to any existing functions.
+
+1. You MUST ALWAYS use grep/ag. Find EVERY other code location that uses your new/modified function.
+
+2. Check: Did your changes just BREAK EVERYTHING somewhere else, which now has to be updated to match? Almost GUARANTEED the answer is YES, and you MUST update the other locations that expected the old function behavior/return type/parameters/exceptions.
+
+3. Check: Do you need to also UPDATE the PHPdoc for those OTHER functions too? OFTEN the answer is YES. For example, if you've changed the exceptions that a deep, internal function throws, then you MUST either catch it in all higher functions and do something with it, OR let it pass through them upwards. And if you do let it pass through and bubble up then you MUST ALSO update the PHPdoc for THAT higher function to say `"@throws TheNewException"` (or delete something in case you changed a subfunction to no longer throw).
+
+4. If your updates to the affected higher-level functions in steps 2/3 means that THOSE other functions now ALSO behave differently (meaning THEY have new return values/exceptions/parameters), then you MUST also do ANOTHER grep/ag to check for anything that uses THOSE functions, and update all of those code locations TOO. And continue that way up the entire chain of functions that call each other, until you reach the top of the project, so that the entire chain of function calls is caught/documented properly. Otherwise, those unexpected (undocumented) exceptions will terminate PHP, so this is very important!
+
+
+
+## Styleguides
+
+### Namespaces
+
+- Organize all classes into logical namespaces.
+
+- We follow the PSR-4 Autoloading standard, which means that you MUST only have ONE class per source code `.php` file. And the namespace AND classname MUST match BOTH its disk path AND its `.php` filename. In our project, the `src/` folder is the `InstagramAPI` namespace, and everything under that is for its subnamespaces (folders) and our classes (PHP files).
+
+Example of a proper class in our top-level namespace:
+
+```php
+src/Something.php:
+<?php
+
+namespace InstagramAPI;
+
+class Something
+{
+    ....
+}
+```
+
+Example of a proper class in a sub-namespace:
+
+```php
+src/Wonderful/Things/Something.php:
+<?php
+
+namespace InstagramAPI\Wonderful\Things;
+
+class Something
+{
+    ....
+}
+```
+
+### Functions and Variables
+
+- You MUST split all function declaration/definition arguments onto separate lines, but only IF the function takes arguments. This is done for clarity, and to avoid unintentional bugs by contributors. It ensures that any changes to function arguments will be diffed as a single-line change. It's more readable. And it's the style _we_ use.
+
+Example of a function that takes no arguments:
+
+```php
+public function doSomething()
+{
+    ...
+}
+```
+
+Example of a function that takes one argument:
+
+```php
+public function doSomething(
+    $foo = null)
+{
+    ...
+}
+```
+
+Example of a function that takes multiple arguments:
+
+```php
+public function doSomething(
+    $foo,
+    $bar = '',
+    $baz = null)
+{
+    ...
+}
+```
+
+- All properties and functions MUST be named using `camelCase`, NOT `snake_case`. (The _only_ exception to this rule is Instagram's server response property objects, meaning everything in the `src/Response/` folder, since _their_ server replies can use underscores.)
+- Private and protected properties/functions MUST be _prefixed_ with an underscore, to clearly show that they are internal inside the class and _cannot_ be used from the outside. But the PUBLIC properties/functions MUST _NEVER_ be prefixed with an underscore (_except_ the _obvious_, specially named, built-in PHP double-underscore ones such as `public function __construct()`). And also note that function _arguments_ (such as in setters) MUST NEVER be prefixed by underscores.
+
+Example of a class with proper function and property underscore prefixes for private/protected members, and with the proper function argument style:
+
+```php
+class Something
+{
+    public $publicProperty;
+    protected $_protectedProperty;
+    private $_privateProperty;
+
+    public function getProtectedProperty()
+    {
+        return $this->_protectedProperty;
+    }
+
+    public function setProtectedProperty(
+        $protectedProperty)
+    {
+        $this->_protectedProperty = $protectedProperty;
+    }
+
+    public function getPublicProperty()
+    {
+        return $this->_publicProperty;
+    }
+
+    public function setPublicProperty(
+        $publicProperty)
+    {
+        $this->publicProperty = $publicProperty;
+    }
+
+    protected function _somethingInternal()
+    {
+        ...
+    }
+
+    ...
+}
+```
+
+- All functions and variables MUST have descriptive names that document their purpose automatically. Use names like `$videoFilename` and `$deviceInfo` and so on, so that the code documents itself instead of needing tons of comments to explain what each step is doing.
+
+Examples of BAD variable names:
+
+```php
+$x = $po + $py;
+$w = floor($h * $ar);
+```
+
+Examples of GOOD variable names:
+
+```php
+$endpoint = $this->url.'?'.http_build_query($this->params);
+$this->_aspectRatio = (float) ($this->_width / $this->_height);
+$width = floor($this->_height * $this->_maxAspectRatio);
+```
+
+- All functions MUST have occasional comments that explain what they're doing in their various substeps. Look at our codebase and follow our commenting style.
+
+- Our comments start with a capital letter and end in punctuation, and describe the purpose in as few words as possible, such as: `// Default request options (immutable after client creation).`
+
+- All functions MUST do as little work as possible, so that they are easy to maintain and bugfix.
+
+Example of a GOOD function layout:
+
+```php
+function requestVideoURL(...);
+
+function uploadVideoChunks(...);
+
+function configureVideo(...);
+
+function uploadVideo(...)
+{
+    $url = $this->requestVideoURL();
+    if (...handle any errors from the previous function)
+
+    $uploadResult = $this->uploadVideoChunks($url, ...);
+
+    $this->configureVideo($uploadResult, ...);
+}
+```
+
+Example of a BAD function layout:
+
+```php
+function uploadVideo(...)
+{
+    // Request upload URL.
+    // Upload video data to URL.
+    // Configure its location property.
+    // Post it to a timeline.
+    // Call your grandmother.
+    // Make some tea.
+    // ...and 500 other lines of code.
+}
+```
+
+- All function parameter lists MUST be well-thought out so that they list the most important arguments FIRST and so that they are as SIMPLE as possible to EXTEND in the FUTURE, since Instagram's API changes occasionally.
+
+Avoid this kind of function template:
+
+```php
+function uploadVideo($videoFilename, $filter, $url, $caption, $usertags, $hashtags);
+```
+
+Make such multi-argument functions take future-extensible option-arrays instead, especially if you expect that more properties may be added in the future.
+
+So the above would instead be PROPERLY designed as follows:
+
+```php
+function uploadVideo($videoFilename, array $metadata);
+```
+
+Now users can just say `uploadVideo($videoFilename, ['hashtags'=>$hashtags]);`, and we can easily add more metadata fields in the future without ever breaking backwards-compatibility with projects that are using our function!
+
+### Function Documentation
+
+- All functions MUST have _COMPLETE_ PHPdoc doc-blocks. The critically important information is the single-sentence `summary-line` (ALWAYS), then the `detailed description` (if necessary), then the `@param` descriptions (if any), then the `@throws` (one for EVERY type of exception that it throws, even uncaught ones thrown from DEEPER functions called within this function), then the `@return` (if the function returns something), and lastly one or more `@see` if there's any need for a documentation reference to a URL or another function or class.
+
+Example of a properly documented function:
+
+```php
+    /**
+     * Generates a User Agent string from a Device (<< that is the REQUIRED ONE-SENTENCE summary-line).
+     *
+     * [All lines after that are the optional description. This function didn't need any,
+     *  but you CAN use this area to provide extra information describing things worth knowing.]
+     *
+     * @param \InstagramAPI\Devices\Device $device The Android device.
+     * @param string[]|null                $names (optional) Array of name-strings.
+     *
+     * @throws \InvalidArgumentException                  If the device parameter is invalid.
+     * @throws \InstagramAPI\Exception\InstagramException In case of invalid or failed API response.
+     *
+     * @return string
+     *
+     * @see otherFunction()
+     * @see http://some-url...
+     */
+    public static function buildUserAgent(
+        Device $device,
+        $names = null)
+    {
+        ...
+    }
+```
+
+- You MUST take EXTREMELY GOOD CARE to ALWAYS _perfectly_ document ALL parameters, the EXACT return-type, and ALL thrown exceptions. All other project developers RELY on the function-documentation ALWAYS being CORRECT! With incorrect documentation, other developers would make incorrect assumptions and _severe_ bugs would be introduced!
+
+### Exceptions
+
+- ALL thrown exceptions that can happen inside a function or in ANY of its SUB-FUNCTION calls MUST be documented as `@throws`, so that we get a COMPLETE OVERVIEW of ALL exceptions that may be thrown when we call the function. YES, that EVEN means exceptions that come from deeper function calls, whose exceptions are NOT being caught by your function and which will therefore bubble up if they're thrown by those deeper sub-functions!
+- Always remember that Exceptions WILL CRITICALLY BREAK ALL OTHER CODE AND STOP PHP'S EXECUTION if not handled or documented properly! They are a LOT of responsibility! So you MUST put a LOT OF TIME AND EFFORT into PROPERLY handling (_catching and doing something_) for ALL exceptions that your function should handle, AND adding PHPdoc _documentation_ about the ones that your function DOESN'T catch/handle internally and which WILL therefore bubble upwards and would possibly BREAK other code (which is EXACTLY what would happen if an exception ISN'T documented by you and someone then uses your bad function and doesn't "catch" your exception since YOU didn't tell them that it can be thrown)!
+- All of our internal exceptions derive from `\InstagramAPI\Exception\InstagramException`, so it's always safe to declare that one as a `@throws \InstagramAPI\Exception\InstagramException` if you're calling anything that throws exceptions based on our internal `src/Exception/*.php` system. But it's even better if you can pinpoint which exact exceptions are thrown, by looking at the functions you're calling and seeing their `@throws` documentation, WHICH OF COURSE DEPENDS ON PEOPLE HAVING WRITTEN PROPER `@throws` FOR THOSE OTHER FUNCTIONS SO THAT _YOU_ KNOW WHAT THE FUNCTIONS YOU'RE CALLING WILL THROW. DO YOU SEE _NOW_ HOW IMPORTANT IT IS TO DECLARE EXCEPTIONS PROPERLY AND TO _ALWAYS_ KEEP THAT LIST UP TO DATE
+- Whenever you are using an EXTERNAL LIBRARY that throws its own custom exceptions (meaning NOT one of the standard PHP ones such as `\Exception` or `\InvalidArgumentException`, etc), then you MUST ALWAYS re-wrap the exception into some appropriate exception from our own library instead, otherwise users will not be able to say `catch (\InstagramAPI\Exception\InstagramException $e)`, since the 3rd party exceptions wouldn't be derived from our base exception and wouldn't be caught, thus breaking the user's program. To solve that, look at the design of our `src/Exception/NetworkException.php`, which we use in `src/Client.php` to re-wrap all Guzzle exceptions into our own exception type instead. Read the source-code of our NetworkException and it will explain how to properly re-wrap 3rd party exceptions and how to ensure that your re-wrapped exception will give users helpful messages and helpful stack traces.
+
+
+# Contributing new endpoints
+
+In order to add endpoints to the API you will need to capture the requests first. For that, you can use any HTTPS proxy you want. You can find a lot of information about this on the internet. Remember that you need to install a root CA (Certificate Authority) in your device so that the proxy can decrypt the requests and show them to you.
+
+Also be aware that you cannot capture Instagram for iPhone's requests. The iPhone API parameters are totally different and they are NOT compatible with this Android API library! You MUST use a real Android APK when capturing requests!
+
+Once you have the endpoint and necessary parameters, how do you add them to this library? Easy, you can follow this example:
+
+```php
+    public function getAwesome(
+        array $userList)
+    {
+        return $this->ig->request('awesome/endpoint/')
+            ->setSignedPost(false)
+            ->addPost('_uuid', $this->ig->uuid)
+            ->addPost('user_ids', implode(',', $userList))
+            ->addPost('_csrftoken', $this->ig->client->getToken())
+            ->getResponse(new Response\AwesomeResponse());
+    }
+```
+
+In the example above you can see `('awesome/endpoint/')` which is the endpoint you captured. We are simulating a POST request, so you can add POST parameters easily by doing `->addPost('_uuid', $this->uuid)`.
+
+Which is basically:
+
+```php
+->addPost(key, value)
+```
+
+Where key is the name of the POST param, and value is whatever value the server requires for that parameter.
+
+Some of the requests are signed. This means there is a hash concatenated with the JSON. In order to make a signed request, we can enable or disable signing with the following line:
+
+```php
+->setSignedPost($isSigned)
+```
+
+`$isSigned` is boolean, so if you want a signed request, you simply set it to `true`.
+
+If the request is a GET request, you can add the GET query parameters like this (instead of using `addPost`):
+
+```php
+->addParam(key, value)
+```
+
+And finally, we always end with the `getResponse` function call, which will read the response and return an object with all of the server response values:
+
+```php
+->getResponse(new Response\AwesomeResponse());
+```
+
+Now you might be wondering how to create that response class? But there is nothing to worry about... it's very simple!
+
+Imagine that you have the following response:
+
+```json
+{"items": [{"user": {"is_verified": false, "has_anonymous_profile_picture": false, "is_private": false, "full_name": "awesome", "username": "awesome", "pk": "uid", "profile_pic_url": "profilepic"}, "large_urls": [], "caption": "", "thumbnail_urls": ["thumb1", "thumb2", "thumb3", "thumb4"]}], "status": "ok"}
+```
+
+You can use [http://jsoneditoronline.org](http://jsoneditoronline.org/) for a better visualization:
+
+<img src="https://s29.postimg.org/3xyopcbg7/insta_help.jpg" width="300">
+
+(Alternatively, if you're an advanced user, you can create an empty response-class (with no defined properties yet), and then use its `->printJson()` function to look at its contents in a beautifully readable way.)
+
+So your new `src/Response/AwesomeResponse.php` class should contain one `JSON_PROPERTY_MAP` property named `items`. Our magical [LazyJsonMapper](https://github.com/lazyjsonmapper/lazyjsonmapper) object mapping system needs a PHPdoc-style type-definition to tell us if the property is another class, a float, an int, a string, a string array, etc. By default, if you don't specify any type (if you set its value to `''`), it will treat the JSON value as whatever type PHP detected it as internally during JSON decoding (such as a string, int, float, bool, etc).
+
+In this scenario, your `src/Response/AwesomeResponse.php` file and its property definitions should look as follows, since we want to map `items` to an array of `Suggestion` objects:
+
+```php
+<?php
+
+namespace InstagramAPI\Response;
+
+use InstagramAPI\Response;
+
+class AwesomeResponse extends Response
+{
+    const JSON_PROPERTY_MAP = [
+        'items' => 'Model\Suggestion[]',
+    ];
+}
+```
+
+The `items` property will now expect an array of Suggestion model objects. And `src/Response/Model/Suggestion.php` should look like this:
+
+```php
+<?php
+
+namespace InstagramAPI\Response\Model;
+
+use InstagramAPI\AutoPropertyMapper;
+
+class Suggestion extends AutoPropertyMapper
+{
+    const JSON_PROPERTY_MAP = [
+        'media_infos'    => '',
+        'social_context' => '',
+        'algorithm'      => '',
+        'thumbnail_urls' => 'string[]',
+        'value'          => '',
+        'caption'        => '',
+        'user'           => 'User',
+        'large_urls'     => 'string[]',
+        'media_ids'      => '',
+        'icon'           => '',
+    ];
+}
+```
+
+Here in this `Suggestion` class you can see many variables that didn't appear in our example endpoint's response, but that's because many other requests _re-use_ the same object, and depending the request, their response contents may differ a bit. Also note that unlike the AwesomeResponse class, the actual Model objects (the files in in `src/Response/Model/`) _don't_ use the "Model\" prefix when referring to other model objects, since they are in the same namespace already.
+
+Also note that many of the properties above are defined as `''` (no type), which means "mixed/untyped". It simply means that the value is not forcibly converted to anything. That's how you should define most properties unless you have a specific reason to force anything to a specific type.
+
+It is also _extremely important_ that any properties relating to Media IDs, PKs, User PKs, etc, _must_ be declared as a `string`, otherwise they may be handled as a float/int which won't fit on 32-bit CPUs and will truncate the number, leading to the wrong data. Just look at all other Model objects that are already in this project, and be sure that any ID/PK fields in your own new Model object are properly tagged as `string` type too!
+
+Now you can test your new endpoint, in order to look at its response object:
+
+```
+$awesome = $i->getAwesome(['123']);
+$awesome->printJson(); // Look at the object data.
+$awesome->printPropertyDescriptions(); // Look at all defined properties.
+```
+
+And finally, how do you access the object's data? Via the magical [LazyJsonMapper](https://github.com/lazyjsonmapper/lazyjsonmapper), which your Response and Model objects inherit from! It automatically creates getters and setters for all properties, and has a million other features!
+
+```php
+$items = $awesome->getItems();
+$user = $items[0]->getUser();
+
+// LazyJsonMapper even lets you look at the JSON of specific sub-objects:
+$user->printJson();
+```
+
+Lastly, you may sometimes be implementing an endpoint which uses a nearly empty response with just the standard `status` and/or `message` (and `_messages`) fields, and no other fields. In that case, there's already a pre-made response which you should use: `GenericResponse`. Search the source code for that word and you'll find many endpoints where we use that basic response. Use it to easily add new endpoint implementations whenever there's no extra data to extract!
+
+We hope that you found this tutorial useful! :smile:

+Reciprocal Public License (RPL-1.5)
+
+Version 1.5, July 15, 2007
+
+Copyright (C) 2001-2007
+Technical Pursuit Inc.,
+All Rights Reserved.
+
+
+PREAMBLE
+
+The Reciprocal Public License (RPL) is based on the concept of reciprocity or,
+if you prefer, fairness.
+
+In short, this license grew out of a desire to close loopholes in previous open
+source licenses, loopholes that allowed parties to acquire open source software
+and derive financial benefit from it without having to release their
+improvements or derivatives to the community which enabled them. This occurred
+any time an entity did not release their application to a "third party".
+
+While there is a certain freedom in this model of licensing, it struck the
+authors of the RPL as being unfair to the open source community at large and to
+the original authors of the works in particular. After all, bug fixes,
+extensions, and meaningful and valuable derivatives were not consistently
+finding their way back into the community where they could fuel further, and
+faster, growth and expansion of the overall open source software base.
+
+While you should clearly read and understand the entire license, the essence of
+the RPL is found in two definitions: "Deploy" and "Required Components".
+
+Regarding deployment, under the RPL your changes, bug fixes, extensions, etc.
+must be made available to the open source community at large when you Deploy in
+any form -- either internally or to an outside party. Once you start running
+the software you have to start sharing the software.
+
+Further, under the RPL all components you author including schemas, scripts,
+source code, etc. -- regardless of whether they're compiled into a single
+binary or used as two halves of client/server application -- must be shared.
+You have to share the whole pie, not an isolated slice of it.
+
+In addition to these goals, the RPL was authored to meet the requirements of
+the Open Source Definition as maintained by the Open Source Initiative (OSI).
+
+The specific terms and conditions of the license are defined in the remainder
+of this document.
+
+

+other intellectual property of Licensor or any Contributor except as expressly
+stated herein. Except as expressly stated in Sections 3 and 4, no other patent
+rights, express or implied, are granted herein. Your Extensions may require
+additional patent licenses from Licensor or Contributors which each may grant
+in its sole discretion. No right is granted to the trademarks of Licensor or
+any Contributor even if such marks are included in the Licensed Software.
+Nothing in this License shall be interpreted to prohibit Licensor from
+licensing under different terms from this License any code that Licensor
+otherwise would have a right to license.
+
+5.1 You expressly acknowledge and agree that although Licensor and each
+Contributor grants the licenses to their respective portions of the Licensed
+Software set forth herein, no assurances are provided by Licensor or any
+Contributor that the Licensed Software does not infringe the patent or other
+intellectual property rights of any other entity. Licensor and each
+Contributor disclaim any liability to You for claims brought by any other
+entity based on infringement of intellectual property rights or otherwise. As
+a condition to exercising the rights and licenses granted hereunder, You
+hereby assume sole responsibility to secure any other intellectual property
+rights needed, if any. For example, if a third party patent license is
+required to allow You to distribute the Licensed Software, it is Your
+responsibility to acquire that license before distributing the Licensed
+Software.
+
+6.0 Your Obligations And Grants. In consideration of, and as an express
+condition to, the licenses granted to You under this License You hereby agree
+that any Modifications, Derivative Works, or Required Components (collectively
+Extensions) that You create or to which You contribute are governed by the
+terms of this License including, without limitation, Section 4. Any Extensions
+that You create or to which You contribute must be Deployed under the terms of
+this License or a future version of this License released under Section 7. You
+hereby grant to Licensor and all third parties a world-wide, non-exclusive,
+royalty-free license under those intellectual property rights You own or
+control to use, reproduce, display, perform, modify, create derivatives,
+sublicense, and distribute Licensed Software, in any form. Any Extensions You
+make and Deploy must have a distinct title so as to readily tell any
+subsequent user or Contributor that the Extensions are by You. You must
+include a copy of this License or directions on how to obtain a copy with
+every copy of the Extensions You distribute. You agree not to offer or impose
+any terms on any Source Code or executable version of the Licensed Software,
+or its Extensions that alter or restrict the applicable version of this
+License or the recipients' rights hereunder.
+
+6.1 Availability of Source Code. You must make available, under the terms of
+this License, the Source Code of any Extensions that You Deploy, via an
+Electronic Distribution Mechanism. The Source Code for any version that You
+Deploy must be made available within one (1) month of when you Deploy and must
+remain available for no less than twelve (12) months after the date You cease
+to Deploy. You are responsible for ensuring that the Source Code to each
+version You Deploy remains available even if the Electronic Distribution
+Mechanism is maintained by a third party. You may not charge a fee for any
+copy of the Source Code distributed under this Section in excess of Your
+actual cost of duplication and distribution of said copy.
+
+6.2 Description of Modifications. You must cause any Modifications that You
+create or to which You contribute to be documented in the Source Code, clearly
+describing the additions, changes or deletions You made. You must include a
+prominent statement that the Modifications are derived, directly or indirectly,
+from the Licensed Software and include the names of the Licensor and any
+Contributor to the Licensed Software in (i) the Source Code and (ii) in any
+notice displayed by the Licensed Software You distribute or in related
+documentation in which You describe the origin or ownership of the Licensed
+Software. You may not modify or delete any pre-existing copyright notices,
+change notices or License text in the Licensed Software without written
+permission of the respective Licensor or Contributor.
+
+6.3 Intellectual Property Matters.
+
+a. Third Party Claims. If You have knowledge that a license to a third party's
+intellectual property right is required to exercise the rights granted by this
+License, You must include a human-readable file with Your distribution that
+describes the claim and the party making the claim in sufficient detail that a
+recipient will know whom to contact.
+
+b. Contributor APIs. If Your Extensions include an application programming
+interface ("API") and You have knowledge of patent licenses that are
+reasonably necessary to implement that API, You must also include this
+information in a human-readable file supplied with Your distribution.
+
+c. Representations. You represent that, except as disclosed pursuant to 6.3(a)
+above, You believe that any Extensions You distribute are Your original
+creations and that You have sufficient rights to grant the rights conveyed by
+this License.
+
+6.4 Required Notices.
+
+a. License Text. You must duplicate this License or instructions on how to
+acquire a copy in any documentation You provide along with the Source Code of
+any Extensions You create or to which You contribute, wherever You describe
+recipients' rights relating to Licensed Software.
+
+b. License Notice. You must duplicate any notice contained in EXHIBIT A (the
+"License Notice") in each file of the Source Code of any copy You distribute
+of the Licensed Software and Your Extensions. If You create an Extension, You
+may add Your name as a Contributor to the Source Code and accompanying
+documentation along with a description of the contribution. If it is not
+possible to put the License Notice in a particular Source Code file due to its
+structure, then You must include such License Notice in a location where a
+user would be likely to look for such a notice.
+
+c. Source Code Availability. You must notify the software community of the
+availability of Source Code to Your Extensions within one (1) month of the date
+You initially Deploy and include in such notification a description of the
+Extensions, and instructions on how to acquire the Source Code. Should such
+instructions change you must notify the software community of revised
+instructions within one (1) month of the date of change. You must provide
+notification by posting to appropriate news groups, mailing lists, weblogs, or
+other sites where a publicly accessible search engine would reasonably be
+expected to index your post in relationship to queries regarding the Licensed
+Software and/or Your Extensions.
+
+d. User-Visible Attribution. You must duplicate any notice contained in
+EXHIBIT B (the "User-Visible Attribution Notice") in each user-visible display
+of the Licensed Software and Your Extensions which delineates copyright,
+ownership, or similar attribution information. If You create an Extension,
+You may add Your name as a Contributor, and add Your attribution notice, as an
+equally visible and functional element of any User-Visible Attribution Notice
+content. To ensure proper attribution, You must also include such User-Visible
+Attribution Notice in at least one location in the Software documentation
+where a user would be likely to look for such notice.
+
+6.5 Additional Terms. You may choose to offer, and charge a fee for, warranty,
+support, indemnity or liability obligations to one or more recipients of
+Licensed Software. However, You may do so only on Your own behalf, and not on
+behalf of the Licensor or any Contributor except as permitted under other
+agreements between you and Licensor or Contributor. You must make it clear that
+any such warranty, support, indemnity or liability obligation is offered by You
+alone, and You hereby agree to indemnify the Licensor and every Contributor for
+any liability plus attorney fees, costs, and related expenses due to any such
+action or claim incurred by the Licensor or such Contributor as a result of
+warranty, support, indemnity or liability terms You offer.
+
+6.6 Conflicts With Other Licenses. Where any portion of Your Extensions, by
+virtue of being Derivative Works of another product or similar circumstance,
+fall under the terms of another license, the terms of that license should be
+honored however You must also make Your Extensions available under this
+License. If the terms of this License continue to conflict with the terms of
+the other license you may write the Licensor for permission to resolve the
+conflict in a fashion that remains consistent with the intent of this License.
+Such permission will be granted at the sole discretion of the Licensor.
+
+7.0 Versions of This License. Licensor may publish from time to time revised
+versions of the License. Once Licensed Software has been published under a
+particular version of the License, You may always continue to use it under the
+terms of that version. You may also choose to use such Licensed Software under
+the terms of any subsequent version of the License published by Licensor. No
+one other than Licensor has the right to modify the terms applicable to
+Licensed Software created under this License.
+
+7.1 If You create or use a modified version of this License, which You may do
+only in order to apply it to software that is not already Licensed Software
+under this License, You must rename Your license so that it is not confusingly
+similar to this License, and must make it clear that Your license contains
+terms that differ from this License. In so naming Your license, You may not
+use any trademark of Licensor or of any Contributor. Should Your modifications
+to this License be limited to alteration of a) Section 13.8 solely to modify
+the legal Jurisdiction or Venue for disputes, b) EXHIBIT A solely to define
+License Notice text, or c) to EXHIBIT B solely to define a User-Visible
+Attribution Notice, You may continue to refer to Your License as the
+Reciprocal Public License or simply the RPL.
+
+8.0 Disclaimer of Warranty. LICENSED SOFTWARE IS PROVIDED UNDER THIS LICENSE
+ON AN "AS IS" BASIS, WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESS OR IMPLIED,
+INCLUDING, WITHOUT LIMITATION, WARRANTIES THAT THE LICENSED SOFTWARE IS FREE
+OF DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING.
+FURTHER THERE IS NO WARRANTY MADE AND ALL IMPLIED WARRANTIES ARE DISCLAIMED
+THAT THE LICENSED SOFTWARE MEETS OR COMPLIES WITH ANY DESCRIPTION OF
+PERFORMANCE OR OPERATION, SAID COMPATIBILITY AND SUITABILITY BEING YOUR
+RESPONSIBILITY. LICENSOR DISCLAIMS ANY WARRANTY, IMPLIED OR EXPRESSED, THAT
+ANY CONTRIBUTOR'S EXTENSIONS MEET ANY STANDARD OF COMPATIBILITY OR DESCRIPTION
+OF PERFORMANCE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LICENSED SOFTWARE IS WITH YOU. SHOULD LICENSED SOFTWARE PROVE DEFECTIVE IN ANY
+RESPECT, YOU (AND NOT THE LICENSOR OR ANY OTHER CONTRIBUTOR) ASSUME THE COST
+OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. UNDER THE TERMS OF THIS
+LICENSOR WILL NOT SUPPORT THIS SOFTWARE AND IS UNDER NO OBLIGATION TO ISSUE
+UPDATES TO THIS SOFTWARE. LICENSOR HAS NO KNOWLEDGE OF ERRANT CODE OR VIRUS IN
+THIS SOFTWARE, BUT DOES NOT WARRANT THAT THE SOFTWARE IS FREE FROM SUCH ERRORS
+OR VIRUSES. THIS DISCLAIMER OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS
+LICENSE. NO USE OF LICENSED SOFTWARE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS
+DISCLAIMER.
+
+9.0 Limitation of Liability. UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY,
+WHETHER TORT (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL THE
+LICENSOR, ANY CONTRIBUTOR, OR ANY DISTRIBUTOR OF LICENSED SOFTWARE, OR ANY
+SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR ANY INDIRECT,
+SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY CHARACTER INCLUDING,
+WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL, WORK STOPPAGE, COMPUTER
+FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER COMMERCIAL DAMAGES OR LOSSES,
+EVEN IF SUCH PARTY SHALL HAVE BEEN INFORMED OF THE POSSIBILITY OF SUCH
+DAMAGES. THIS LIMITATION OF LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH
+OR PERSONAL INJURY RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT
+APPLICABLE LAW PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE
+EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS
+EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.
+
+10.0 High Risk Activities. THE LICENSED SOFTWARE IS NOT FAULT-TOLERANT AND IS
+NOT DESIGNED, MANUFACTURED, OR INTENDED FOR USE OR DISTRIBUTION AS ON-LINE
+CONTROL EQUIPMENT IN HAZARDOUS ENVIRONMENTS REQUIRING FAIL-SAFE PERFORMANCE,
+SUCH AS IN THE OPERATION OF NUCLEAR FACILITIES, AIRCRAFT NAVIGATION OR
+COMMUNICATIONS SYSTEMS, AIR TRAFFIC CONTROL, DIRECT LIFE SUPPORT MACHINES, OR
+WEAPONS SYSTEMS, IN WHICH THE FAILURE OF THE LICENSED SOFTWARE COULD LEAD
+DIRECTLY TO DEATH, PERSONAL INJURY, OR SEVERE PHYSICAL OR ENVIRONMENTAL DAMAGE
+("HIGH RISK ACTIVITIES"). LICENSOR AND CONTRIBUTORS SPECIFICALLY DISCLAIM ANY
+EXPRESS OR IMPLIED WARRANTY OF FITNESS FOR HIGH RISK ACTIVITIES.
+
+11.0 Responsibility for Claims. As between Licensor and Contributors, each
+party is responsible for claims and damages arising, directly or indirectly,
+out of its utilization of rights under this License which specifically
+disclaims warranties and limits any liability of the Licensor. This paragraph
+is to be used in conjunction with and controlled by the Disclaimer Of
+Warranties of Section 8, the Limitation Of Damages in Section 9, and the
+disclaimer against use for High Risk Activities in Section 10. The Licensor
+has thereby disclaimed all warranties and limited any damages that it is or
+may be liable for. You agree to work with Licensor and Contributors to
+distribute such responsibility on an equitable basis consistent with the terms
+of this License including Sections 8, 9, and 10. Nothing herein is intended or
+shall be deemed to constitute any admission of liability.
+
+12.0 Termination. This License and all rights granted hereunder will terminate
+immediately in the event of the circumstances described in Section 13.6 or if
+applicable law prohibits or restricts You from fully and or specifically
+complying with Sections 3, 4 and/or 6, or prevents the enforceability of any
+of those Sections, and You must immediately discontinue any use of Licensed
+Software.
+
+12.1 Automatic Termination Upon Breach. This License and the rights granted
+hereunder will terminate automatically if You fail to comply with the terms
+herein and fail to cure such breach within thirty (30) days of becoming aware
+of the breach. All sublicenses to the Licensed Software that are properly
+granted shall survive any termination of this License. Provisions that, by
+their nature, must remain in effect beyond the termination of this License,
+shall survive.
+
+12.2 Termination Upon Assertion of Patent Infringement. If You initiate
+litigation by asserting a patent infringement claim (excluding declaratory
+judgment actions) against Licensor or a Contributor (Licensor or Contributor
+against whom You file such an action is referred to herein as "Respondent")
+alleging that Licensed Software directly or indirectly infringes any patent,
+then any and all rights granted by such Respondent to You under Sections 3 or
+4 of this License shall terminate prospectively upon sixty (60) days notice
+from Respondent (the "Notice Period") unless within that Notice Period You
+either agree in writing (i) to pay Respondent a mutually agreeable reasonably
+royalty for Your past or future use of Licensed Software made by such
+Respondent, or (ii) withdraw Your litigation claim with respect to Licensed
+Software against such Respondent. If within said Notice Period a reasonable
+royalty and payment arrangement are not mutually agreed upon in writing by the
+parties or the litigation claim is not withdrawn, the rights granted by
+Licensor to You under Sections 3 and 4 automatically terminate at the
+expiration of said Notice Period.
+
+12.3 Reasonable Value of This License. If You assert a patent infringement
+claim against Respondent alleging that Licensed Software directly or
+indirectly infringes any patent where such claim is resolved (such as by
+license or settlement) prior to the initiation of patent infringement
+litigation, then the reasonable value of the licenses granted by said
+Respondent under Sections 3 and 4 shall be taken into account in determining
+the amount or value of any payment or license.
+
+12.4 No Retroactive Effect of Termination. In the event of termination under
+this Section all end user license agreements (excluding licenses to
+distributors and resellers) that have been validly granted by You or any
+distributor hereunder prior to termination shall survive termination.
+
+13.0 Miscellaneous.
+
+13.1 U.S. Government End Users. The Licensed Software is a "commercial item,"
+as that term is defined in 48 C.F.R. 2.101 (Oct. 1995), consisting of
+"commercial computer software" and "commercial computer software
+documentation," as such terms are used in 48 C.F.R. 12.212 (Sept. 1995).
+Consistent with 48 C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4
+(June 1995), all U.S. Government End Users acquire Licensed Software with only
+those rights set forth herein.
+
+13.2 Relationship of Parties. This License will not be construed as creating
+an agency, partnership, joint venture, or any other form of legal association
+between or among You, Licensor, or any Contributor, and You will not represent
+to the contrary, whether expressly, by implication, appearance, or otherwise.
+
+13.3 Independent Development. Nothing in this License will impair Licensor's
+right to acquire, license, develop, subcontract, market, or distribute
+technology or products that perform the same or similar functions as, or
+otherwise compete with, Extensions that You may develop, produce, market, or
+distribute.
+
+13.4 Consent To Breach Not Waiver. Failure by Licensor or Contributor to
+enforce any provision of this License will not be deemed a waiver of future enforcement
+of that or any other provision.
+
+13.5 Severability. This License represents the complete agreement concerning
+the subject matter hereof. If any provision of this License is held to be
+unenforceable, such provision shall be reformed only to the extent necessary
+to make it enforceable.
+
+13.6 Inability to Comply Due to Statute or Regulation. If it is impossible for
+You to comply with any of the terms of this License with respect to some or
+all of the Licensed Software due to statute, judicial order, or regulation,
+then You cannot use, modify, or distribute the software.
+
+13.7 Export Restrictions. You may be restricted with respect to downloading or
+otherwise acquiring, exporting, or reexporting the Licensed Software or any
+underlying information or technology by United States and other applicable
+laws and regulations. By downloading or by otherwise obtaining the Licensed
+Software, You are agreeing to be responsible for compliance with all
+applicable laws and regulations.
+
+13.8 Arbitration, Jurisdiction & Venue. This License shall be governed by
+Colorado law provisions (except to the extent applicable law, if any, provides
+otherwise), excluding its conflict-of-law provisions. You expressly agree that
+any dispute relating to this License shall be submitted to binding arbitration
+under the rules then prevailing of the American Arbitration Association. You
+further agree that Adams County, Colorado USA is proper venue and grant such
+arbitration proceeding jurisdiction as may be appropriate for purposes of
+resolving any dispute under this License. Judgement upon any award made in
+arbitration may be entered and enforced in any court of competent
+jurisdiction. The arbitrator shall award attorney's fees and costs of
+arbitration to the prevailing party. Should either party find it necessary to
+enforce its arbitration award or seek specific performance of such award in a
+civil court of competent jurisdiction, the prevailing party shall be entitled
+to reasonable attorney's fees and costs. The application of the United Nations
+Convention on Contracts for the International Sale of Goods is expressly

+----------
+## Installation
+
+### Dependencies
+
+Install/enable the required php extensions and dependencies. You can learn how to do so [here](https://github.com/mgp25/Instagram-API/wiki/Dependencies).
+
+### Install this library
+We use composer to distribute our code effectively and easily. If you do not already have composer installed, you can download and install it here [here](https://getcomposer.org/download/).
+
+Once you have composer installed, you can do the following:
+```sh
+composer require mgp25/instagram-php
+```
+
+```php
+require __DIR__.'/../vendor/autoload.php';
+
+$ig = new \InstagramAPI\Instagram();
+```
+
+If you want to test new and possibly unstable code that is in the master branch, and which hasn't yet been released, then you can do the following (at your own risk):
+
+```sh
+composer require mgp25/instagram-php dev-master
+```
+
+#### _Warning about moving data to a different server_
+
+_Composer checks your system's capabilities and selects libraries based on your **current** machine (where you are running the `composer` command). So if you run Composer on machine `A` to install this library, it will check machine `A`'s capabilities and will install libraries appropriate for that machine (such as installing the PHP 7+ versions of various libraries). If you then move your whole installation to machine `B` instead, it **will not work** unless machine `B` has the **exact** same capabilities (same or higher PHP version and PHP extensions)! Therefore, you should **always** run the Composer-command on your intended target machine instead of your local machine._
+
+## Examples
+
+All examples can be found [here](https://github.com/mgp25/Instagram-API/tree/master/examples).
+
+## Code of Conduct
+
+This project adheres to the Contributor Covenant [code of conduct](CODE_OF_CONDUCT.md).
+By participating, you are expected to uphold this code.
+Please report any unacceptable behavior.
+
+## How do I contribute
+
+If you would like to contribute to this project, please feel free to submit a pull request.
+
+Before you do, take a look at the [contributing guide](https://github.com/mgp25/Instagram-API/blob/master/CONTRIBUTING.md).
+
+## Why did I make this API?
+
+After legal measures, Facebook, WhatsApp and Instagram blocked my accounts.
+In order to use Instagram on my phone I needed a new phone, as they banned my UDID, so that is basically why I made this API.
+
+### What is Instagram?
+According to [the company](https://instagram.com/about/faq/):
+
+> "Instagram is a fun and quirky way to share your life with friends through a series of pictures. Snap a photo with your mobile phone, then choose a filter to transform the image into a memory to keep around forever. We're building Instagram to allow you to experience moments in your friends' lives through pictures as they happen. We imagine a world more connected through photos."
+
+# License
+
+In order help ensure fairness and sharing, this library is dual-licensed. Be
+aware that _all_ usage, unless otherwise specified, is under the **RPL-1.5**
+license!
+
+- Reciprocal Public License 1.5 (RPL-1.5): https://opensource.org/licenses/RPL-1.5
+
+You should read the _entire_ license; especially the `PREAMBLE` at the
+beginning. In short, the word `reciprocal` means "giving something back in
+return for what you are getting". It is _**not** a freeware license_. This
+license _requires_ that you open-source _all_ of your own source code for _any_
+project which uses this library! Creating and maintaining this library is
+endless hard work for us. That's why there is _one_ simple requirement for you:
+Give _something_ back to the world. Whether that's code _or_ financial support
+for this project is entirely up to you, but _nothing else_ grants you _any_
+right to use this library.
+
+Furthermore, the library is _also_ available _to certain entities_ under a
+modified version of the RPL-1.5, which has been modified to allow you to use the
+library _without_ open-sourcing your own project. The modified license
+(see [LICENSE_PREMIUM](https://github.com/mgp25/Instagram-API/blob/master/LICENSE_PREMIUM))
+is granted to certain entities, at _our_ discretion, and for a _limited_ period
+of time (unless otherwise agreed), pursuant to our terms. Currently, we are
+granting this license to all
+"[premium subscribers](https://github.com/mgp25/Instagram-API/issues/2655)" for
+the duration of their subscriptions. You can become a premium subscriber by
+either contributing substantial amounts of high-quality code, or by subscribing
+for a fee. This licensing ensures fairness and stimulates the continued growth
+of this library through both code contributions and the financial support it
+needs.
+
+You are not required to accept this License since you have not signed it,
+however _nothing else_ grants you permission to _use_, copy, distribute, modify,
+or create derivatives of either the Software (this library) or any Extensions
+created by a Contributor. These actions are prohibited by law if you do not
+accept this License. Therefore, by performing any of these actions You indicate
+Your acceptance of this License and Your agreement to be bound by all its terms
+and conditions. IF YOU DO NOT AGREE WITH ALL THE TERMS AND CONDITIONS OF THIS
+LICENSE DO NOT USE, MODIFY, CREATE DERIVATIVES, OR DISTRIBUTE THE SOFTWARE. IF
+IT IS IMPOSSIBLE FOR YOU TO COMPLY WITH ALL THE TERMS AND CONDITIONS OF THIS
+LICENSE THEN YOU CAN NOT USE, MODIFY, CREATE DERIVATIVES, OR DISTRIBUTE THE
+SOFTWARE.
+
+# Terms and conditions
+
+- You will NOT use this API for marketing purposes (spam, botting, harassment, massive bulk messaging...).
+- We do NOT give support to anyone who wants to use this API to send spam or commit other crimes.
+- We reserve the right to block any user of this repository that does not meet these conditions.
+
+## Legal
+
+This code is in no way affiliated with, authorized, maintained, sponsored or endorsed by Instagram or any of its affiliates or subsidiaries. This is an independent and unofficial API. Use at your own risk.

+ * This example demonstrates how to use and customize user settings storages.
+ *
+ * By default, if you don't give us any custom configuration, we will always use
+ * the "File" storage backend, which keeps all data in regular files on disk. It
+ * is a rock-solid backend and will be very good for most people.
+ *
+ * However, other people may want to use something more advanced, such as one of
+ * the other built-in storage backends ("MySQL", "SQLite" and "Memcached"). Or
+ * perhaps you'd even like to build your own backend (doing so is very easy).
+ */
+
+echo "You are not supposed to execute this script. Read it in a text editor to see various storage methods.\n";
+exit;
+
+// These points will give you a basic overview of the process. But you should
+// read the code in src/Settings/ for the full details. It is well documented.
+
+// 1. Choosing a built-in storage backend (one of "file", "mysql", "sqlite" or
+// "memcached"), and using the automatic, default settings for that backend:
+$ig = new \InstagramAPI\Instagram($debug, $truncatedDebug, [
+    'storage' => 'mysql',
+]);
+
+// 2. You can read src/Settings/Factory.php for valid settings for each backend.
+// Here's an example of how to change the default storage location for "file":
+$ig = new \InstagramAPI\Instagram($debug, $truncatedDebug, [
+    'storage'    => 'file',
+    'basefolder' => 'some/path/',
+]);
+
+// 3. And here's an example of how to change the default database filename and
+// the default database table name for the "sqlite" backend:
+$ig = new \InstagramAPI\Instagram($debug, $truncatedDebug, [
+    'storage'     => 'sqlite',
+    'dbfilename'  => 'some/path/foo.db',
+    'dbtablename' => 'mysettings',
+]);
+
+// 4. If you read src/Settings/Factory.php, you'll notice that you can choose
+// the storage backends and most of their parameters via the command line or
+// environment variables instead. For example: "SETTINGS_STORAGE=mysql php
+// yourscript.php" would set the "storage" parameter via the environment, and
+// typing "php yourscript.php --settings_storage=mysql" would set it via the
+// command line. The command-line arguments have the highest precedence, then
+// the environment variables, and lastly the code within your script. This
+// precedence order is so that you can easily override your script's code to
+// test other backends or change their parameters without modifying your code.
+
+// 5. Very advanced users can look in src/Settings/StorageHandler.php to read
+// about hasUser(), moveUser() and deleteUser(). Three very, VERY DANGEROUS
+// commands which let you rename or delete account settings in your storage.
+// Carefully read through their descriptions and use them wisely. If you're sure
+// that you dare to use them, then you can access them via $ig->settings->...
+
+// 6. Yet another super advanced topic is the ability to copy data between
+// backends. For example if you want to move all of your data from a File
+// backend to a database, or vice versa. That kind of action is not supported
+// natively by us, but you CAN do it by directly interfacing with the storages!
+
+// First, you MUST manually build a list of all users you want to migrate.
+// You can either hardcode this list. Or get it via something like a directory
+// scan (to look at existing folders in a File backend storage path), or a
+// database query to get all "username" values from the old database. If you're
+// using a database, you will have to connect to it manually and query it
+// yourself! There's no way to do it automatically! Just build this array any
+// way you want to do it!
+$migrateUsers = [
+    'someuser',
+    'another.user',
+    'very_awesome_user123',
+];
+
+// Secondly, you must connect to your old and new storages. These are just
+// example values. The array format is the exact same as what's given to the
+// `Instagram()` constructor! And if you give an empty array, you'll use the
+// same default File backend that the main class uses! So if you want to migrate
+// from that, you should just set oldStorage to `createHandler([])`!
+$oldStorage = \InstagramAPI\Settings\Factory::createHandler([
+    'storage'     => 'sqlite',
+    'dbfilename'  => 'app/instagram.sqlite',
+    'dbtablename' => 'instagram_sessions',
+]);
+$newStorage = \InstagramAPI\Settings\Factory::createHandler([
+    'storage'     => 'file',
+    'basefolder'  => 'some/path/',
+]);
+
+// Now just run the migration process. This will copy all cookies and settings
+// from the old storage to the new storage, for all of the "migrateUsers".
+foreach ($migrateUsers as $user) {
+    if (!$oldStorage->hasUser($user)) {
+        die("Unable to migrate '{$user}' from old storage (user doesn't exist).\n");
+    }
+
+    echo "Migrating '{$user}'.\n";
+
+    $oldStorage->setActiveUser($user);
+    $newStorage->setActiveUser($user);
+
+    $newStorage->setCookies((string) $oldStorage->getCookies());
+    foreach (\InstagramAPI\Settings\StorageHandler::PERSISTENT_KEYS as $key) {
+        $newStorage->set($key, (string) $oldStorage->get($key));
+    }
+}
+
+// 7. Lastly... if you want to implement your own completely CUSTOM STORAGE,
+// then you simply have to do one thing: Implement the StorageInterface class
+// interface. But be very sure to STRICTLY follow ALL rules for storage backends
+// described in that interface's docs, otherwise your custom backend WON'T work.
+//
+// See the overview in src/Settings/StorageInterface.php, and then read through
+// the various built-in storage backends in src/Settings/Storage/ to see perfect
+// implementations that completely follow the required interface specification.
+//
+// Also note that PDO-based backends should be derived from our "PDOStorage"
+// storage sub-component, so that the logic is perfectly implemented and not
+// duplicated. That's exactly how our "sqlite" and "mysql" PDO backends work!
+//
+// To use your custom storage backend, you would simply create your own class
+// similar to the built-in backends. But do NOT put your own class in our
+// src/Settings/Storage/ folder. Store your class inside your own project.
+//
+// Then simply provide your custom storage class instance as the storage class:
+$ig = new \InstagramAPI\Instagram($debug, $truncatedDebug, [
+    'storage' => 'custom',
+    'class'   => new MyCustomStorage(), // Whatever you've named your class.
+]);
+
+// That's it! This should get you started on your journey. :-)
+
+// And please think about contributing your WELL-WRITTEN storage backends to
+// this project! If you had a reason to write your own, then there's probably
+// someone else out there with the same need. Remember to SHARE with the open
+// source community! ;-)

+/**
+ * Internal list of verified Android devices.
+ *
+ * @author SteveJobzniak (https://github.com/SteveJobzniak)
+ *
+ * This is a list of popular, modern Android phones, all VERIFIED to support
+ * receiving the max-resolution videos from Instagram's API replies. This list
+ * has to be hand-crafted, because bad devices only receive low-resolution
+ * videos! Instagram's API looks at device MODEL when deciding to deliver HD.
+ *
+ * The goal with this list is to have a list of ~10 modern phones which we only
+ * have to refresh every few years, as they slip away into obscurity.
+ *
+ * Here are the rules for building the list:
+ *
+ * - Find a top-list of the best Android phones for [current year].
+ * - Only select devices with super high resolution screens (at least 1080p+).
+ * - Find the model at https://www.handsetdetection.com/properties/devices.
+ * - Some phones have tons of sub-models. Find the phone on Amazon and look at
+ *   the details to find sub-model identifier for the most popular US variant!
+ * - Research the model's popularity. For example, NEVER include a Samsung phone
+ *   with an "X" suffix (such as SM-G935X). Those are STORE DEMO units.
+ * - Check if they've recorded any Instagram user agent. If there are multiple
+ *   agents for Instagram, compare them all carefully and pick the latest.
+ * - Look closely to make sure the string wasn't truncated or modified on their
+ *   site. I've seen phones lacking the locale and final parenthesis, for
+ *   example. Or strings that are all-lowercase. DO NOT USE THOSE!
+ * - Verify the device details by doing a Google search for the model identifier
+ *   you found in the user-agent, to verify all specs match the real device.
+ * - Enter good models below in the same format as the other devices. Triple and
+ *   quadruple check that it is 100% CORRECT for that device.
+ * - Always enter the EXACT Android version that the user agent was seen with on
+ *   the website above, which is usually the OS version the phone released with.
+ * - The Android version is the first part of the agent, such as "23/6.0.1".
+ *
+ * Here's an example string:
+ * "Instagram 10.9.0 Android (23/6.0.1; 480dpi; 1080x1776; LENOVO/Lenovo; Lenovo P2a42; P2a42; qcom; fr_FR)".
+ *
+ * The format is made via the android.os.Build library:
+ * "Instagram %s Android (%s/%s; %s; %s; %s/%s; %s; %s; %s)
+ * 1. Instagram VERSION.
+ * 2. Android API VERSION (Build$VERSION.SDK_INT)
+ * 3. Android VERSION (Build$VERSION.RELEASE)
+ * 4. DPI.
+ * 5. Display Resolution.
+ * 6. MANUFACTURER.
+ * 7 (optional). BRAND (this "/"-portion with a brand doesn't always exist).
+ * 8. MODEL.
+ * 9. DEVICE.
+ * 10. CPU (Build.HARDWARE)
+ * 11. Language (Build.LOCALE).
+ *
+ * We only want the part within parenthesis, and we ignore the locale.
+ *
+ * That gives us the following string:
+ * "23/6.0.1; 480dpi; 1080x1776; LENOVO/Lenovo; Lenovo P2a42; P2a42; qcom".
+ *
+ * However, note that the device above isn't at least 1920x1080. Don't use it.

+ * When you have a "possibly good" agent, you must finally TEST IT: Use the
+ * "devtools/checkDevices.php" developer script to check your agent and verify
+ * that Instagram detects it as a high-resolution device and gives it HD videos!
+ *
+ *
+ * LASTLY, YOU MUST UNDERSTAND THE FOLLOWING: THE DEVICE LIST BELOW IS MEANT TO
+ * BE A "SNAPSHOT" OF DEVICES AND THEIR ANDROID VERSIONS AT THAT MOMENT IN TIME.
+ * WE ARE *ONLY* SUPPOSED TO *ADD* NEW DEVICES TO IT OR COMPLETELY *DELETE* OLD
+ * DEVICES. DO *NOT* "EDIT" THE LIST TO TRY TO "IMPROVE" OR "UPDATE" ANDROID
+ * VERSIONS OR *ANYTHING* ELSE ABOUT AN EXISTING DEVICE. EDITING EVEN A *SINGLE*
+ * BYTE WILL CAUSE *ALL* USERS OF THAT DEVICE TO BE LOGGED OUT AND *RE-ASSIGNED*
+ * TO A BRAND NEW PHONE HARDWARE FINGERPRINT AND A DIFFERENT RANDOM DEVICE. THAT
+ * BEHAVIOR IS INTENTIONAL AND *BY DESIGN*. IT ALLOWS US TO SAFELY BLACKLIST BAD
+ * DEVICES AND IT DISCOURAGES DUMB, FRIVOLOUS "UPGRADES", THUS ENSURING THAT WE
+ * *ONLY* IDENTIFY OUR DEVICES WITH THE ACTUAL *ANDROID* VERSION THEY *SHIPPED*
+ * WITH, WHICH IS THE SAFEST WAY TO IDENTIFY OUR VIRTUAL DEVICES. MOST REAL
+ * USERS DON'T UPGRADE ANDROID OS BEYOND WHAT THE PHONE ORIGINALLY SHIPPED WITH.
+ *
+ *
+ * THIS DEVICE LIST IS CRITICAL TO THE OPERATION OF THE API. DO NOT CONTRIBUTE
+ * TO THIS LIST IF YOU DON'T UNDERSTAND *ALL* INSTRUCTIONS ABOVE. PERFECTLY. ALL
+ * CONTRIBUTIONS MUST INCLUDE THE RELEASE DATE, HANDSETDETECTION AND A LINK TO A
+ * PAGE (SUCH AS AMAZON) FOR THAT EXACT MODEL SPECIFIER, AS SEEN BELOW, SO THAT
+ * WE CAN VALIDATE ALL AGENTS TO SEE THAT YOU AREN'T ADDING AN INCORRECTLY
+ * WRITTEN OR UNPOPULAR DEVICE AGENT WHICH WILL GET US BANNED BY INSTAGRAM!

+     *
+     * - "horCropFocus" (int): Crop focus position (-50 .. 50) when cropping
+     *   horizontally (reducing width). Uses intelligent guess if not set.
+     *
+     * - "verCropFocus" (int): Crop focus position (-50 .. 50) when cropping
+     *   vertically (reducing height). Uses intelligent guess if not set.
+     *
+     * - "minAspectRatio" (float): Minimum allowed aspect ratio. Uses
+     *   auto-selected class constants (with the correct, legal Instagram
+     *   aspect ratio limits for your chosen target feed) if not set.
+     *
+     * - "maxAspectRatio" (float): Maximum allowed aspect ratio. Uses
+     *   auto-selected class constants (with the correct, legal Instagram
+     *   aspect ratio limits for your chosen target feed) if not set.
+     *
+     * - "forceAspectRatio" (float|int): Tell the media processor to enforce a
+     *   specific aspect ratio target. This custom value MUST be within the
+     *   "minAspectRatio" to "maxAspectRatio" range! NOTE: When your goal is to
+     *   generate a custom media aspect ratio, you should normally ONLY specify
+     *   THIS parameter and should NEVER tamper with the min/max aspect ratio
+     *   limits! Because when you're specifying a custom forced ratio here, we
+     *   WILL ALWAYS verify/process the media as-necessary to fit your desired
+     *   ratio (EVEN if the input media was "already valid" within the overall,
+     *   larger legal min/max ratio ranges). ALSO NOTE: We WON'T process input
+     *   media when it's already VERY close to the desired target ratio. The
+     *   ONLY custom aspect ratio value that is 100% guaranteed to be FULLY
+     *   ENFORCED is `1.0` (square). If you specify ANY other ratio, we will
+     *   accept a VERY SMALL deviation when the media is already almost exactly
+     *   at the desired ratio. This is done to prevent pointless "impossible
+     *   processing", since achieving EXACT non-`1.0` ratios is almost always
+     *   IMPOSSIBLE, so it's not worth trying with media that's already very
+     *   close. The reason why non-`1.0` ratios are impossibly hard to hit in
+     *   MOST cases, is because pixels cannot be subdivided into smaller
+     *   fractions than "1 whole pixel", so in most cases when we ask for
+     *   something like `1.25385` ratio and we have an input file such as
+     *   `640x512` (`1.25` ratio), it is PHYSICALLY IMPOSSIBLE to achieve a
+     *   `1.25385` ratio with that input and we could AT BEST reach a tiny
+     *   fraction away from that target; such as `641x512` (`1.251953125`
+     *   ratio), `639x512` (`1.248046875` ratio), `640x513` (`1.247563353`
+     *   ratio) or `640x511` (`1.252446184` ratio). So whether you CAN hit your
+     *   EXACT desired non-`1.0` ratio or NOT depends 100% on your input file's
+     *   resolution! That's why we passthrough files that are already super
+     *   close to the desired ratio. Either way, such a tiny difference in
+     *   aspect ratio won't be visible to the eye, so if you are using this
+     *   "target ratio" feature for creating Instagram albums where all media
+     *   has the same aspect ratio, the final result WILL still look perfect.
+     *
+     * - "useRecommendedRatio" (bool): Whether to use the recommended aspect
+     *   ratio for your specific media type and target feed (such as using an
+     *   appropriate `9:16` portrait widescreen for stories). Some targets use
+     *   the recommended ratio by default, and others disable this by default.
+     *   Therefore, you do NOT need to set this option manually unless you have
+     *   a VERY special reason to do so! NOTE: This will ALWAYS be set to
+     *   `FALSE` if you're using the "forceAspectRatio" parameter!
+     *
+     * - "allowNewAspectDeviation" (bool): Whether to allow the new, final
+     *   aspect ratio (during processing) to deviate slightly from the MIN/MAX
+     *   limits. By setting this option to `TRUE`, you will tell our processing
+     *   to allow "slightly too high/slightly too low" final aspect ratios
+     *   (instead of throwing an exception) and to still permit the final
+     *   "closest-possible canvas" we've calculated anyway. You should NEVER
+     *   need to use this feature, but if you have manually configured extremely
+     *   narrow min/max aspect ratio parameters (which your input media CANNOT
+     *   be tweaked to fit perfectly within) then you MAY want to enable this.
+     *
+     * - "bgColor" (array) - Array with 3 color components `[R, G, B]`
+     *   (0-255/0x00-0xFF) for the background. Uses white if not set.
+     *
+     * - "blurredBorder" (bool) - Whether to use the media as a blurred border.
+     *   False if not set.
+     *
+     * - "operation" (int) - Operation to perform on the media (CROP or EXPAND).
+     *   Uses `self::CROP` if not set.
+     *
+     * - "tmpPath" (string) - Path to temp directory. Uses system temp location
+     *   or the class-default (`self::$defaultTmpPath`) if not set.

+/**
+ * Data Storage Interface.
+ *
+ * These methods must be implemented by all storage backends. All of their input
+ * and output validation is already done by the owning Settings class, so that
+ * backends can focus on dealing with basic, fully verified data (instead of
+ * writing and maintaining a bunch of boilerplate code to verify parameters).
+ *
+ * All functions in this file are listed in roughly the sequence they're called
+ * during normal operation. You can completely trust that they are called in a
+ * sane order and that you do not need to validate the call order.
+ *
+ * -- HOW TO STORE DATA: --
+ *
+ * The ONLY datatype we use for settings is STRINGS. You absolutely MUST store
+ * ALL data as strings. Do NOT attempt any "fancy" formats such as "database INT
+ * columns", because we will OFTEN be storing empty strings in all fields. Your
+ * storage backends MUST use STRING storage and MUST allow EMPTY strings.
+ *
+ * Data length varies, but it's a VERY bad idea for you to cap the length. We
+ * may need to store very long data someday. For example, the cookie data that
+ * we already store is usually around 2000 characters long.
+ *
+ * Furthermore, do NOT make ANY assumptions about what settings-"keys/columns"
+ * we will be storing. There is a list in StorageHandler::PERSISTENT_KEYS, but
+ * it will DEFINITELY change several times in the future. If you hardcode those
+ * columns, you will be in trouble in the future. Therefore, the absolute BEST
+ * encoding method is to use a SINGLE file/database column for the settings and
+ * to JSON-encode everything. And to use a SINGLE file/database column for the
+ * cookies and simply store our raw cookie string as-provided.
+ *
+ * -- MAJOR WARNING: --
+ *
+ * Backend developers are NOT allowed to violate ANY aspect of this interface
+ * specification. ANY exceptions thrown MUST be of the EXACT types listed, and
+ * ALL return values MUST be of the EXACT types listed. This means that YOU will
+ * have to handle ALL exceptions thrown by your particular backend solution, and
+ * re-wrapping them as the required exceptions if necessary. Otherwise you WILL
+ * BREAK all user applications that use your terrible Storage implementation.
+ *
+ * Just look at our existing Storage implementations to see correct code.

+<h1>Instagram-API Warning!</h1>
+<h2>Can I run this library via a website?</h2>
+<p>No. Don't do it. You cannot <em>safely</em> use this <em><strong>or any other</strong> 3rd party Instagram libraries</em> directly via a website!</p>
+<p>This library (and <em>all other</em> 3rd party reverse engineered Instagram libraries), is made for command line usage in a terminal by running the script like a program (such as <code>php yourscript.php</code>). We do <strong>not</strong> recommend running this library via a web browser! Because browsers will terminate the PHP process as soon as the user closes their connection to the page (closes the tab, or presses "Stop loading page"), which means that your script can terminate at any moment. This library is not a webpage! It is an Instagram for Android application emulator. It emulates an <strong>application</strong>. Not a webpage. You cannot just randomly kill this library in the middle of work! (You might kill it while it's writing to disk or calling some important APIs!)</p>
+<p>And furthermore, if it's used on a webpage then it must waste time logging in to Instagram every time the user refreshes the webpage, since each page load would start a new script (meaning "a new Instagram app emulator") from scratch. And there are also massive risks about concurrent access from multiple web requests to a single user account which can corrupt your settings-storage or cookies. So we really, <em>really</em> do not recommend running this library via a browser! It's a <em>very</em> bad idea!</p>
+<p>Instead, you should run your Instagram app emulator script as a permanent 24/7 process, and make it dump data to a database which your regular website reads from, or make some kind of permanent localhost daemon that can listen locally on the server and receive queries on a port (localhost queries from the main website's scripts), and then performing those queries via the API and responding to the website script with something like JSON or with serialized <code>src/Response/</code> objects, which the website script then transforms for final display to the user.</p>
+<p>You must also be sure that your permanent process periodically calls <code>login()</code> inside your 24/7 PHP process, to emulate the Instagram for Android application being closed/opened and refreshing itself (like a real user would do). Otherwise it will soon get banned or silently limited as a "detected bot" by Instagram due to never calling login. Preferably use the same refresh ranges we use by default, so that you refresh <code>login()</code> within a random range between every 30 minutes, or at max every 6 hours.</p>
+<p>So, to recap: Make your "Instagram application" part a permanent process, and then make your webpage interact with that permanent process or an intermediary database in some way. That's the <em>proper</em> architecture system if you want to use this library online! Imagine it like your website talking to a phone and telling its permanently running Instagram app to do things. <em>That's</em> the proper design and that's how you have to think about things.</p>
+<p>Never forget this fact: This library (and <em>all</em> other 3rd party libraries) is an Android application emulator. It is not a website and will <em>never</em> be able to become a website (because the Android application is not a website!). Therefore, we will <em>never</em> give support to anyone who decides to use the library directly inside a webpage. If you do that, it's <em>at your own risk</em>! It is a really terrible and unsupported idea!</p>

+# Changelog
+
+All notable changes to this project will be documented in this file, in reverse chronological order by release.
+
+## 1.0.1 - 2016-08-06
+
+### Added
+
+- Nothing.
+
+### Deprecated
+
+- Nothing.
+
+### Removed
+
+- Nothing.
+
+### Fixed
+
+- Updated all `@return self` annotation references in interfaces to use
+  `@return static`, which more closelly follows the semantics of the
+  specification.
+- Updated the `MessageInterface::getHeaders()` return annotation to use the
+  value `string[][]`, indicating the format is a nested array of strings.
+- Updated the `@link` annotation for `RequestInterface::withRequestTarget()`
+  to point to the correct section of RFC 7230.
+- Updated the `ServerRequestInterface::withUploadedFiles()` parameter annotation
+  to add the parameter name (`$uploadedFiles`).
+- Updated a `@throws` annotation for the `UploadedFileInterface::moveTo()`
+  method to correctly reference the method parameter (it was referencing an
+  incorrect parameter name previously).
+
+## 1.0.0 - 2016-05-18
+
+Initial stable release; reflects accepted PSR-7 specification.

+PSR Http Message
+================
+
+This repository holds all interfaces/classes/traits related to
+[PSR-7](http://www.php-fig.org/psr/psr-7/).
+
+Note that this is not a HTTP message implementation of its own. It is merely an
+interface that describes a HTTP message. See the specification for more details.
+
+Usage
+-----
+
+We'll certainly need some stuff in here.

+PSR Log
+=======
+
+This repository holds all interfaces/classes/traits related to
+[PSR-3](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md).
+
+Note that this is not a logger of its own. It is merely an interface that
+describes a logger. See the specification for more details.
+
+Installation
+------------
+
+```bash
+composer require psr/log
+```
+
+Usage
+-----
+
+If you need a logger, you can use the interface like this:
+
+```php
+<?php
+
+use Psr\Log\LoggerInterface;
+
+class Foo
+{
+    private $logger;
+
+    public function __construct(LoggerInterface $logger = null)
+    {
+        $this->logger = $logger;
+    }
+
+    public function doSomething()
+    {
+        if ($this->logger) {
+            $this->logger->info('Doing work');
+        }
+
+        // do something useful
+    }
+}
+```
+
+You can then pick one of the implementations of the interface to get a logger.
+
+If you want to implement the interface, you can require this package and
+implement `Psr\Log\LoggerInterface` in your code. Please read the
+[specification text](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md)
+for details.

+# Cache

+[![Build Status](https://travis-ci.org/reactphp/cache.svg?branch=master)](https://travis-ci.org/reactphp/cache)
+
+Async, [Promise](https://github.com/reactphp/promise)-based cache interface
+for [ReactPHP](https://reactphp.org/).
+
+The cache component provides a
+[Promise](https://github.com/reactphp/promise)-based
+[`CacheInterface`](#cacheinterface) and an in-memory [`ArrayCache`](#arraycache)
+implementation of that.
+This allows consumers to type hint against the interface and third parties to
+provide alternate implementations.
+This project is heavily inspired by
+[PSR-16: Common Interface for Caching Libraries](https://www.php-fig.org/psr/psr-16/),
+but uses an interface more suited for async, non-blocking applications.

+## Usage
+
+### CacheInterface
+
+The `CacheInterface` describes the main interface of this component.
+This allows consumers to type hint against the interface and third parties to
+provide alternate implementations.
+
+#### get()
+
+The `get(string $key, mixed $default = null): PromiseInterface<mixed>` method can be used to
+retrieve an item from the cache.
+
+This method will resolve with the cached value on success or with the
+given `$default` value when no item can be found or when an error occurs.
+Similarly, an expired cache item (once the time-to-live is expired) is
+considered a cache miss.
+
+```php
+$cache
+    ->get('foo')
+    ->then('var_dump');
+```
+
+This example fetches the value of the key `foo` and passes it to the
+`var_dump` function. You can use any of the composition provided by
+[promises](https://github.com/reactphp/promise).
+
+#### set()
+
+The `set(string $key, mixed $value, ?float $ttl = null): PromiseInterface<bool>` method can be used to
+store an item in the cache.
+
+This method will resolve with `true` on success or `false` when an error
+occurs. If the cache implementation has to go over the network to store
+it, it may take a while.
+
+The optional `$ttl` parameter sets the maximum time-to-live in seconds
+for this cache item. If this parameter is omitted (or `null`), the item
+will stay in the cache for as long as the underlying implementation
+supports. Trying to access an expired cache item results in a cache miss,
+see also [`get()`](#get).
+
+```php
+$cache->set('foo', 'bar', 60);
+```
+
+This example eventually sets the value of the key `foo` to `bar`. If it
+already exists, it is overridden.
+
+This interface does not enforce any particular TTL resolution, so special
+care may have to be taken if you rely on very high precision with
+millisecond accuracy or below. Cache implementations SHOULD work on a
+best effort basis and SHOULD provide at least second accuracy unless
+otherwise noted. Many existing cache implementations are known to provide
+microsecond or millisecond accuracy, but it's generally not recommended
+to rely on this high precision.
+
+This interface suggests that cache implementations SHOULD use a monotonic
+time source if available. Given that a monotonic time source is only
+available as of PHP 7.3 by default, cache implementations MAY fall back
+to using wall-clock time.
+While this does not affect many common use cases, this is an important
+distinction for programs that rely on a high time precision or on systems
+that are subject to discontinuous time adjustments (time jumps).
+This means that if you store a cache item with a TTL of 30s and then
+adjust your system time forward by 20s, the cache item SHOULD still
+expire in 30s.
+
+#### delete()
+
+The `delete(string $key): PromiseInterface<bool>` method can be used to
+delete an item from the cache.
+
+This method will resolve with `true` on success or `false` when an error
+occurs. When no item for `$key` is found in the cache, it also resolves
+to `true`. If the cache implementation has to go over the network to
+delete it, it may take a while.
+
+```php
+$cache->delete('foo');
+```
+
+This example eventually deletes the key `foo` from the cache. As with
+`set()`, this may not happen instantly and a promise is returned to
+provide guarantees whether or not the item has been removed from cache.
+
+#### getMultiple()
+
+The `getMultiple(string[] $keys, mixed $default = null): PromiseInterface<array>` method can be used to
+retrieve multiple cache items by their unique keys.
+
+This method will resolve with an array of cached values on success or with the
+given `$default` value when an item can not be found or when an error occurs.
+Similarly, an expired cache item (once the time-to-live is expired) is
+considered a cache miss.
+
+```php
+$cache->getMultiple(array('name', 'age'))->then(function (array $values) {
+    $name = $values['name'] ?? 'User';
+    $age = $values['age'] ?? 'n/a';
+
+    echo $name . ' is ' . $age . PHP_EOL;
+});
+```
+
+This example fetches the cache items for the `name` and `age` keys and
+prints some example output. You can use any of the composition provided
+by [promises](https://github.com/reactphp/promise).
+
+#### setMultiple()
+
+The `setMultiple(array $values, ?float $ttl = null): PromiseInterface<bool>` method can be used to
+persist a set of key => value pairs in the cache, with an optional TTL.
+
+This method will resolve with `true` on success or `false` when an error
+occurs. If the cache implementation has to go over the network to store
+it, it may take a while.
+
+The optional `$ttl` parameter sets the maximum time-to-live in seconds
+for these cache items. If this parameter is omitted (or `null`), these items
+will stay in the cache for as long as the underlying implementation
+supports. Trying to access an expired cache items results in a cache miss,
+see also [`getMultiple()`](#getmultiple).
+
+```php
+$cache->setMultiple(array('foo' => 1, 'bar' => 2), 60);
+```
+
+This example eventually sets the list of values - the key `foo` to `1` value 
+and the key `bar` to `2`. If some of the keys already exist, they are overridden.
+
+#### deleteMultiple()
+
+The `setMultiple(string[] $keys): PromiseInterface<bool>` method can be used to
+delete multiple cache items in a single operation.
+
+This method will resolve with `true` on success or `false` when an error
+occurs. When no items for `$keys` are found in the cache, it also resolves
+to `true`. If the cache implementation has to go over the network to
+delete it, it may take a while.
+
+```php
+$cache->deleteMultiple(array('foo', 'bar, 'baz'));
+```
+
+This example eventually deletes keys `foo`, `bar` and `baz` from the cache. 
+As with `setMultiple()`, this may not happen instantly and a promise is returned to
+provide guarantees whether or not the item has been removed from cache.
+
+#### clear()
+
+The `clear(): PromiseInterface<bool>` method can be used to
+wipe clean the entire cache.
+
+This method will resolve with `true` on success or `false` when an error
+occurs. If the cache implementation has to go over the network to
+delete it, it may take a while.
+
+```php
+$cache->clear();
+```
+
+This example eventually deletes all keys from the cache. As with `deleteMultiple()`, 
+this may not happen instantly and a promise is returned to provide guarantees 
+whether or not all the items have been removed from cache.
+
+#### has()
+
+The `has(string $key): PromiseInterface<bool>` method can be used to
+determine whether an item is present in the cache.
+
+This method will resolve with `true` on success or `false` when no item can be found 
+or when an error occurs. Similarly, an expired cache item (once the time-to-live 
+is expired) is considered a cache miss.
+
+```php
+$cache
+    ->has('foo')
+    ->then('var_dump');
+```
+
+This example checks if the value of the key `foo` is set in the cache and passes 
+the result to the `var_dump` function. You can use any of the composition provided by
+[promises](https://github.com/reactphp/promise).
+
+NOTE: It is recommended that has() is only to be used for cache warming type purposes
+and not to be used within your live applications operations for get/set, as this method
+is subject to a race condition where your has() will return true and immediately after,
+another script can remove it making the state of your app out of date.
+
+### ArrayCache
+
+The `ArrayCache` provides an in-memory implementation of the [`CacheInterface`](#cacheinterface).
+
+```php
+$cache = new ArrayCache();
+
+$cache->set('foo', 'bar');
+```
+
+Its constructor accepts an optional `?int $limit` parameter to limit the
+maximum number of entries to store in the LRU cache. If you add more
+entries to this instance, it will automatically take care of removing
+the one that was least recently used (LRU).
+
+For example, this snippet will overwrite the first value and only store
+the last two entries:
+
+```php
+$cache = new ArrayCache(2);
+
+$cache->set('foo', '1');
+$cache->set('bar', '2');
+$cache->set('baz', '3');
+```
+
+This cache implementation is known to rely on wall-clock time to schedule
+future cache expiration times when using any version before PHP 7.3,
+because a monotonic time source is only available as of PHP 7.3 (`hrtime()`).
+While this does not affect many common use cases, this is an important
+distinction for programs that rely on a high time precision or on systems
+that are subject to discontinuous time adjustments (time jumps).
+This means that if you store a cache item with a TTL of 30s on PHP < 7.3
+and then adjust your system time forward by 20s, the cache item may
+expire in 10s. See also [`set()`](#set) for more details.
+
+## Common usage
+
+### Fallback get
+
+A common use case of caches is to attempt fetching a cached value and as a
+fallback retrieve it from the original data source if not found. Here is an
+example of that:
+
+```php
+$cache
+    ->get('foo')
+    ->then(function ($result) {
+        if ($result === null) {
+            return getFooFromDb();
+        }
+        
+        return $result;
+    })
+    ->then('var_dump');
+```
+
+First an attempt is made to retrieve the value of `foo`. A callback function is 
+registered that will call `getFooFromDb` when the resulting value is null. 
+`getFooFromDb` is a function (can be any PHP callable) that will be called if the 
+key does not exist in the cache.
+
+`getFooFromDb` can handle the missing key by returning a promise for the
+actual value from the database (or any other data source). As a result, this
+chain will correctly fall back, and provide the value in both cases.
+
+### Fallback get and set
+
+To expand on the fallback get example, often you want to set the value on the
+cache after fetching it from the data source.
+
+```php
+$cache
+    ->get('foo')
+    ->then(function ($result) {
+        if ($result === null) {
+            return $this->getAndCacheFooFromDb();
+        }
+        
+        return $result;
+    })
+    ->then('var_dump');
+
+public function getAndCacheFooFromDb()
+{
+    return $this->db
+        ->get('foo')
+        ->then(array($this, 'cacheFooFromDb'));
+}
+
+public function cacheFooFromDb($foo)
+{
+    $this->cache->set('foo', $foo);
+
+    return $foo;
+}
+```
+
+By using chaining you can easily conditionally cache the value if it is
+fetched from the database.
+

+    (#110 by @clue and @WyriHaximus)
+
+    ```php
+    $resolver->resolveAll('reactphp.org', Message::TYPE_AAAA)->then(function ($ips) {
+        echo 'IPv6 addresses for reactphp.org ' . implode(', ', $ips) . PHP_EOL;
+    });
+    ```
+
+*   Feature: Support parsing `NS`, `TXT`, `MX`, `SOA` and `SRV` records.

+    to avoid cache poisoning attacks and deprecate legacy `Executor`.
+    (#101 and #103 by @clue)
+
+*   Feature: Forward compatibility with Cache 0.5
+    (#102 by @clue)
+
+*   Deprecate legacy `Query::$currentTime` and binary parser data attributes to clean up and simplify API.
+    (#99 by @clue)
+
+## 0.4.13 (2018-02-27)
+
+*   Add `Config::loadSystemConfigBlocking()` to load default system config
+    and support parsing DNS config on all supported platforms
+    (`/etc/resolv.conf` on Unix/Linux/Mac and WMIC on Windows)
+    (#92, #93, #94 and #95 by @clue)
+
+    ```php
+    $config = Config::loadSystemConfigBlocking();
+    $server = $config->nameservers ? reset($config->nameservers) : '8.8.8.8';
+    ```
+
+*   Remove unneeded cyclic dependency on react/socket
+    (#96 by @clue)
+
+## 0.4.12 (2018-01-14)
+
+*   Improve test suite by adding forward compatibility with PHPUnit 6,
+    test against PHP 7.2, fix forward compatibility with upcoming EventLoop releases,
+    add test group to skip integration tests relying on internet connection
+    and add minor documentation improvements.
+    (#85 and #87 by @carusogabriel, #88 and #89 by @clue and #83 by @jsor)
+
+## 0.4.11 (2017-08-25)
+
+*   Feature: Support resolving from default hosts file
+    (#75, #76 and #77 by @clue)
+
+    This means that resolving hosts such as `localhost` will now work as
+    expected across all platforms with no changes required:
+
+    ```php
+    $resolver->resolve('localhost')->then(function ($ip) {
+        echo 'IP: ' . $ip;
+    });
+    ```
+
+    The new `HostsExecutor` exists for advanced usage and is otherwise used
+    internally for this feature.
+
+## 0.4.10 (2017-08-10)
+
+* Feature: Forward compatibility with EventLoop v1.0 and v0.5 and

+
+* Documentation and examples for advanced usage
+  (#66 by @WyriHaximus)
+
+* Remove broken TCP code, do not retry with invalid TCP query
+  (#73 by @clue)
+
+* Improve test suite by fixing HHVM build for now again and ignore future HHVM build errors and
+  lock Travis distro so new defaults will not break the build and
+  fix failing tests for PHP 7.1
+  (#68 by @WyriHaximus and #69 and #72 by @clue)
+
+## 0.4.9 (2017-05-01)
+
+* Feature: Forward compatibility with upcoming Socket v1.0 and v0.8
+  (#61 by @clue)

+
+* Feature: Add support for the AAAA record type to the protocol parser
+  (#58 by @othillo)
+
+* Feature: Add support for the PTR record type to the protocol parser
+  (#59 by @othillo)
+
+## 0.4.7 (2017-03-31)
+
+* Feature: Forward compatibility with upcoming Socket v0.6 and v0.7 component
+  (#57 by @clue)
+

+# Dns
+
+[![Build Status](https://travis-ci.org/reactphp/dns.svg?branch=master)](https://travis-ci.org/reactphp/dns)
+
+Async DNS resolver for [ReactPHP](https://reactphp.org/).
+
+The main point of the DNS component is to provide async DNS resolution.
+However, it is really a toolkit for working with DNS messages, and could
+easily be used to create a DNS server.

+
+## Basic usage
+
+The most basic usage is to just create a resolver through the resolver
+factory. All you need to give it is a nameserver, then you can start resolving
+names, baby!
+
+```php
+$loop = React\EventLoop\Factory::create();
+
+$config = React\Dns\Config\Config::loadSystemConfigBlocking();
+$server = $config->nameservers ? reset($config->nameservers) : '8.8.8.8';
+
+$factory = new React\Dns\Resolver\Factory();
+$dns = $factory->create($server, $loop);
+
+$dns->resolve('igor.io')->then(function ($ip) {
+    echo "Host: $ip\n";
+});
+
+$loop->run();
+```
+
+See also the [first example](examples).
+
+The `Config` class can be used to load the system default config. This is an
+operation that may access the filesystem and block. Ideally, this method should
+thus be executed only once before the loop starts and not repeatedly while it is
+running.
+Note that this class may return an *empty* configuration if the system config
+can not be loaded. As such, you'll likely want to apply a default nameserver
+as above if none can be found.
+
+> Note that the factory loads the hosts file from the filesystem once when
+  creating the resolver instance.
+  Ideally, this method should thus be executed only once before the loop starts
+  and not repeatedly while it is running.
+
+But there's more.
+
+## Caching
+
+You can cache results by configuring the resolver to use a `CachedExecutor`:
+
+```php
+$loop = React\EventLoop\Factory::create();
+
+$config = React\Dns\Config\Config::loadSystemConfigBlocking();
+$server = $config->nameservers ? reset($config->nameservers) : '8.8.8.8';
+
+$factory = new React\Dns\Resolver\Factory();
+$dns = $factory->createCached($server, $loop);
+
+$dns->resolve('igor.io')->then(function ($ip) {
+    echo "Host: $ip\n";
+});
+
+...
+
+$dns->resolve('igor.io')->then(function ($ip) {
+    echo "Host: $ip\n";
+});
+
+$loop->run();
+```
+
+If the first call returns before the second, only one query will be executed.
+The second result will be served from an in memory cache.
+This is particularly useful for long running scripts where the same hostnames
+have to be looked up multiple times.
+
+See also the [third example](examples).
+
+### Custom cache adapter
+
+By default, the above will use an in memory cache.
+
+You can also specify a custom cache implementing [`CacheInterface`](https://github.com/reactphp/cache) to handle the record cache instead:
+
+```php
+$cache = new React\Cache\ArrayCache();
+$loop = React\EventLoop\Factory::create();
+$factory = new React\Dns\Resolver\Factory();
+$dns = $factory->createCached('8.8.8.8', $loop, $cache);
+```
+
+See also the wiki for possible [cache implementations](https://github.com/reactphp/react/wiki/Users#cache-implementations).
+
+## Resolver
+
+### resolve()
+
+The `resolve(string $domain): PromiseInterface<string,Exception>` method can be used to
+resolve the given $domain name to a single IPv4 address (type `A` query).
+
+```php
+$resolver->resolve('reactphp.org')->then(function ($ip) {
+    echo 'IP for reactphp.org is ' . $ip . PHP_EOL;
+});
+```
+
+This is one of the main methods in this package. It sends a DNS query
+for the given $domain name to your DNS server and returns a single IP
+address on success.
+
+If the DNS server sends a DNS response message that contains more than
+one IP address for this query, it will randomly pick one of the IP
+addresses from the response. If you want the full list of IP addresses
+or want to send a different type of query, you should use the
+[`resolveAll()`](#resolveall) method instead.
+
+If the DNS server sends a DNS response message that indicates an error
+code, this method will reject with a `RecordNotFoundException`. Its
+message and code can be used to check for the response code.
+
+If the DNS communication fails and the server does not respond with a
+valid response message, this message will reject with an `Exception`.
+
+Pending DNS queries can be cancelled by cancelling its pending promise like so:
+
+```php
+$promise = $resolver->resolve('reactphp.org');
+
+$promise->cancel();
+```
+
+### resolveAll()
+
+The `resolveAll(string $host, int $type): PromiseInterface<array,Exception>` method can be used to
+resolve all record values for the given $domain name and query $type.
+
+```php
+$resolver->resolveAll('reactphp.org', Message::TYPE_A)->then(function ($ips) {
+    echo 'IPv4 addresses for reactphp.org ' . implode(', ', $ips) . PHP_EOL;
+});
+
+$resolver->resolveAll('reactphp.org', Message::TYPE_AAAA)->then(function ($ips) {
+    echo 'IPv6 addresses for reactphp.org ' . implode(', ', $ips) . PHP_EOL;
+});
+```
+
+This is one of the main methods in this package. It sends a DNS query
+for the given $domain name to your DNS server and returns a list with all
+record values on success.
+
+If the DNS server sends a DNS response message that contains one or more
+records for this query, it will return a list with all record values
+from the response. You can use the `Message::TYPE_*` constants to control
+which type of query will be sent. Note that this method always returns a
+list of record values, but each record value type depends on the query
+type. For example, it returns the IPv4 addresses for type `A` queries,
+the IPv6 addresses for type `AAAA` queries, the hostname for type `NS`,
+`CNAME` and `PTR` queries and structured data for other queries. See also
+the `Record` documentation for more details.
+
+If the DNS server sends a DNS response message that indicates an error
+code, this method will reject with a `RecordNotFoundException`. Its
+message and code can be used to check for the response code.
+
+If the DNS communication fails and the server does not respond with a
+valid response message, this message will reject with an `Exception`.
+
+Pending DNS queries can be cancelled by cancelling its pending promise like so:
+
+```php
+$promise = $resolver->resolveAll('reactphp.org', Message::TYPE_AAAA);
+
+$promise->cancel();
+```
+
+## Advanced Usage
+
+### UdpTransportExecutor
+
+The `UdpTransportExecutor` can be used to
+send DNS queries over a UDP transport.
+
+This is the main class that sends a DNS query to your DNS server and is used
+internally by the `Resolver` for the actual message transport.
+
+For more advanced usages one can utilize this class directly.
+The following example looks up the `IPv6` address for `igor.io`.
+
+```php
+$loop = Factory::create();
+$executor = new UdpTransportExecutor($loop);
+
+$executor->query(
+    '8.8.8.8:53', 
+    new Query($name, Message::TYPE_AAAA, Message::CLASS_IN)
+)->then(function (Message $message) {
+    foreach ($message->answers as $answer) {
+        echo 'IPv6: ' . $answer->data . PHP_EOL;
+    }
+}, 'printf');
+
+$loop->run();
+```
+
+See also the [fourth example](examples).
+
+Note that this executor does not implement a timeout, so you will very likely
+want to use this in combination with a `TimeoutExecutor` like this:
+
+```php
+$executor = new TimeoutExecutor(
+    new UdpTransportExecutor($loop),
+    3.0,
+    $loop
+);
+```
+
+Also note that this executor uses an unreliable UDP transport and that it
+does not implement any retry logic, so you will likely want to use this in
+combination with a `RetryExecutor` like this:
+
+```php
+$executor = new RetryExecutor(
+    new TimeoutExecutor(
+        new UdpTransportExecutor($loop),
+        3.0,
+        $loop
+    )
+);
+```
+
+Note that this executor is entirely async and as such allows you to execute
+any number of queries concurrently. You should probably limit the number of
+concurrent queries in your application or you're very likely going to face
+rate limitations and bans on the resolver end. For many common applications,
+you may want to avoid sending the same query multiple times when the first
+one is still pending, so you will likely want to use this in combination with
+a `CoopExecutor` like this:
+
+```php
+$executor = new CoopExecutor(
+    new RetryExecutor(
+        new TimeoutExecutor(
+            new UdpTransportExecutor($loop),
+            3.0,
+            $loop
+        )
+    )
+);
+```
+
+> Internally, this class uses PHP's UDP sockets and does not take advantage
+  of [react/datagram](https://github.com/reactphp/datagram) purely for
+  organizational reasons to avoid a cyclic dependency between the two
+  packages. Higher-level components should take advantage of the Datagram
+  component instead of reimplementing this socket logic from scratch.
+
+### HostsFileExecutor
+
+Note that the above `UdpTransportExecutor` class always performs an actual DNS query.
+If you also want to take entries from your hosts file into account, you may
+use this code:
+
+```php
+$hosts = \React\Dns\Config\HostsFile::loadFromPathBlocking();
+
+$executor = new UdpTransportExecutor($loop);
+$executor = new HostsFileExecutor($hosts, $executor);
+
+$executor->query(
+    '8.8.8.8:53', 
+    new Query('localhost', Message::TYPE_A, Message::CLASS_IN)
+);
+```
+
+## Install
+
+The recommended way to install this library is [through Composer](https://getcomposer.org).
+[New to Composer?](https://getcomposer.org/doc/00-intro.md)
+
+This will install the latest supported version:
+
+```bash
+$ composer require react/dns:^0.4.19
+```
+
+See also the [CHANGELOG](CHANGELOG.md) for details about version upgrades.
+
+This project aims to run on any platform and thus does not require any PHP
+extensions and supports running on legacy PHP 5.3 through current PHP 7+ and
+HHVM.
+It's *highly recommended to use PHP 7+* for this project.
+
+## Tests
+
+To run the test suite, you first need to clone this repo and then install all
+dependencies [through Composer](https://getcomposer.org):
+
+```bash
+$ composer install
+```
+
+To run the test suite, go to the project root and run:
+
+```bash
+$ php vendor/bin/phpunit
+```
+
+The test suite also contains a number of functional integration tests that rely
+on a stable internet connection.
+If you do not want to run these, they can simply be skipped like this:
+
+```bash
+$ php vendor/bin/phpunit --exclude-group internet
+```

+     * The payload data format depends on the record type. As a rule of thumb,
+     * this library will try to express this in a way that can be consumed
+     * easily without having to worry about DNS internals and its binary transport:
+     *
+     * - A:
+     *   IPv4 address string, for example "192.168.1.1".
+     * - AAAA:
+     *   IPv6 address string, for example "::1".
+     * - CNAME / PTR / NS:
+     *   The hostname without trailing dot, for example "reactphp.org".
+     * - TXT:
+     *   List of string values, for example `["v=spf1 include:example.com"]`.
+     *   This is commonly a list with only a single string value, but this
+     *   technically allows multiple strings (0-255 bytes each) in a single
+     *   record. This is rarely used and depending on application you may want
+     *   to join these together or handle them separately. Each string can
+     *   transport any binary data, its character encoding is not defined (often
+     *   ASCII/UTF-8 in practice). [RFC 1464](https://tools.ietf.org/html/rfc1464)
+     *   suggests using key-value pairs such as `["name=test","version=1"]`, but
+     *   interpretation of this is not enforced and left up to consumers of this
+     *   library (used for DNS-SD/Zeroconf and others).
+     * - MX:
+     *   Mail server priority (UINT16) and target hostname without trailing dot,
+     *   for example `{"priority":10,"target":"mx.example.com"}`.
+     *   The payload data uses an associative array with fixed keys "priority"
+     *   (also commonly referred to as weight or preference) and "target" (also
+     *   referred to as exchange). If a response message contains multiple
+     *   records of this type, targets should be sorted by priority (lowest
+     *   first) - this is left up to consumers of this library (used for SMTP).
+     * - SRV:
+     *   Service priority (UINT16), service weight (UINT16), service port (UINT16)
+     *   and target hostname without trailing dot, for example
+     *   `{"priority":10,"weight":50,"port":8080,"target":"example.com"}`.
+     *   The payload data uses an associative array with fixed keys "priority",
+     *   "weight", "port" and "target" (also referred to as name).
+     *   The target may be an empty host name string if the service is decidedly
+     *   not available. If a response message contains multiple records of this
+     *   type, targets should be sorted by priority (lowest first) and selected
+     *   randomly according to their weight - this is left up to consumers of
+     *   this library, see also [RFC 2782](https://tools.ietf.org/html/rfc2782)
+     *   for more details.
+     * - SOA:
+     *   Includes master hostname without trailing dot, responsible person email
+     *   as hostname without trailing dot and serial, refresh, retry, expire and
+     *   minimum times in seconds (UINT32 each), for example:
+     *   `{"mname":"ns.example.com","rname":"hostmaster.example.com","serial":
+     *   2018082601,"refresh":3600,"retry":1800,"expire":60000,"minimum":3600}`.
+     * - Any other unknown type:
+     *   An opaque binary string containing the RDATA as transported in the DNS
+     *   record. For forwards compatibility, you should not rely on this format
+     *   for unknown types. Future versions may add support for new types and
+     *   this may then parse the payload data appropriately - this will not be
+     *   considered a BC break. See the format definition of known types above

+/**
+ * Cooperatively resolves hosts via the given base executor to ensure same query is not run concurrently
+ *
+ * Wraps an existing `ExecutorInterface` to keep tracking of pending queries
+ * and only starts a new query when the same query is not already pending. Once
+ * the underlying query is fulfilled/rejected, it will forward its value to all
+ * promises awaiting the same query.
+ *
+ * This means it will not limit concurrency for queries that differ, for example
+ * when sending many queries for different host names or types.
+ *
+ * This is useful because all executors are entirely async and as such allow you
+ * to execute any number of queries concurrently. You should probably limit the
+ * number of concurrent queries in your application or you're very likely going
+ * to face rate limitations and bans on the resolver end. For many common
+ * applications, you may want to avoid sending the same query multiple times
+ * when the first one is still pending, so you will likely want to use this in
+ * combination with some other executor like this:
+ *
+ * ```php
+ * $executor = new CoopExecutor(
+ *     new RetryExecutor(
+ *         new TimeoutExecutor(
+ *             new UdpTransportExecutor($loop),
+ *             3.0,
+ *             $loop

+/**
+ * Send DNS queries over a UDP transport.
+ *
+ * This is the main class that sends a DNS query to your DNS server and is used
+ * internally by the `Resolver` for the actual message transport.
+ *
+ * For more advanced usages one can utilize this class directly.
+ * The following example looks up the `IPv6` address for `igor.io`.
+ *
+ * ```php
+ * $loop = Factory::create();
+ * $executor = new UdpTransportExecutor($loop);
+ *
+ * $executor->query(
+ *     '8.8.8.8:53',
+ *     new Query($name, Message::TYPE_AAAA, Message::CLASS_IN)
+ * )->then(function (Message $message) {
+ *     foreach ($message->answers as $answer) {
+ *         echo 'IPv6: ' . $answer->data . PHP_EOL;
+ *     }
+ * }, 'printf');
+ *
+ * $loop->run();
+ * ```
+ *
+ * See also the [fourth example](examples).
+ *
+ * Note that this executor does not implement a timeout, so you will very likely
+ * want to use this in combination with a `TimeoutExecutor` like this:
+ *
+ * ```php
+ * $executor = new TimeoutExecutor(
+ *     new UdpTransportExecutor($loop),
+ *     3.0,
+ *     $loop
+ * );
+ * ```
+ *
+ * Also note that this executor uses an unreliable UDP transport and that it
+ * does not implement any retry logic, so you will likely want to use this in
+ * combination with a `RetryExecutor` like this:
+ *
+ * ```php
+ * $executor = new RetryExecutor(
+ *     new TimeoutExecutor(
+ *         new UdpTransportExecutor($loop),
+ *         3.0,
+ *         $loop
+ *     )
+ * );
+ * ```
+ *
+ * Note that this executor is entirely async and as such allows you to execute
+ * any number of queries concurrently. You should probably limit the number of
+ * concurrent queries in your application or you're very likely going to face
+ * rate limitations and bans on the resolver end. For many common applications,
+ * you may want to avoid sending the same query multiple times when the first
+ * one is still pending, so you will likely want to use this in combination with
+ * a `CoopExecutor` like this:
+ *
+ * ```php
+ * $executor = new CoopExecutor(
+ *     new RetryExecutor(
+ *         new TimeoutExecutor(
+ *             new UdpTransportExecutor($loop),
+ *             3.0,
+ *             $loop
+ *         )
+ *     )
+ * );
+ * ```
+ *
+ * > Internally, this class uses PHP's UDP sockets and does not take advantage
+ *   of [react/datagram](https://github.com/reactphp/datagram) purely for
+ *   organizational reasons to avoid a cyclic dependency between the two
+ *   packages. Higher-level components should take advantage of the Datagram
+ *   component instead of reimplementing this socket logic from scratch.

+# EventLoop Component
+
+[![Build Status](https://travis-ci.org/reactphp/event-loop.svg?branch=master)](https://travis-ci.org/reactphp/event-loop)
+[![Code Climate](https://codeclimate.com/github/reactphp/event-loop/badges/gpa.svg)](https://codeclimate.com/github/reactphp/event-loop)
+
+Event loop abstraction layer that libraries can use for evented I/O.
+
+In order for async based libraries to be interoperable, they need to use the
+same event loop. This component provides a common `LoopInterface` that any
+library can target. This allows them to be used in the same loop, with one
+single `run()` call that is controlled by the user.
+
+**Table of Contents**
+
+* [Quickstart example](#quickstart-example)
+* [Usage](#usage)
+* [Loop implementations](#loop-implementations)
+* [Install](#install)
+* [Tests](#tests)
+* [License](#license)
+
+## Quickstart example
+
+Here is an async HTTP server built with just the event loop.
+
+```php
+$loop = React\EventLoop\Factory::create();
+
+$server = stream_socket_server('tcp://127.0.0.1:8080');
+stream_set_blocking($server, 0);
+
+$loop->addReadStream($server, function ($server) use ($loop) {
+    $conn = stream_socket_accept($server);
+    $data = "HTTP/1.1 200 OK\r\nContent-Length: 3\r\n\r\nHi\n";
+    $loop->addWriteStream($conn, function ($conn) use (&$data, $loop) {
+        $written = fwrite($conn, $data);
+        if ($written === strlen($data)) {
+            fclose($conn);
+            $loop->removeStream($conn);
+        } else {
+            $data = substr($data, $written);
+        }
+    });
+});
+
+$loop->addPeriodicTimer(5, function () {
+    $memory = memory_get_usage() / 1024;
+    $formatted = number_format($memory, 3).'K';
+    echo "Current memory usage: {$formatted}\n";
+});
+
+$loop->run();
+```
+
+## Usage
+
+Typical applications use a single event loop which is created at the beginning
+and run at the end of the program.
+
+```php
+// [1]
+$loop = React\EventLoop\Factory::create();
+
+// [2]
+$loop->addPeriodicTimer(1, function () {
+    echo "Tick\n";
+});
+
+$stream = new React\Stream\ReadableResourceStream(
+    fopen('file.txt', 'r'),
+    $loop
+);
+
+// [3]
+$loop->run();
+```
+
+1. The loop instance is created at the beginning of the program. A convenience
+   factory `React\EventLoop\Factory::create()` is provided by this library which
+   picks the best available [loop implementation](#loop-implementations).
+2. The loop instance is used directly or passed to library and application code.
+   In this example, a periodic timer is registered with the event loop which
+   simply outputs `Tick` every second and a
+   [readable stream](https://github.com/reactphp/stream#readableresourcestream)
+   is created by using ReactPHP's
+   [stream component](https://github.com/reactphp/stream) for demonstration
+   purposes.
+3. The loop is run with a single `$loop->run()` call at the end of the program.
+
+## Loop implementations
+
+In addition to the interface there are the following implementations provided:
+
+* `StreamSelectLoop`: This is the only implementation which works out of the
+  box with PHP. It does a simple `select` system call. It's not the most
+  performant of loops, but still does the job quite well.
+
+* `LibEventLoop`: This uses the `libevent` pecl extension. `libevent` itself
+  supports a number of system-specific backends (epoll, kqueue).
+
+* `LibEvLoop`: This uses the `libev` pecl extension
+  ([github](https://github.com/m4rw3r/php-libev)). It supports the same
+  backends as libevent.
+
+* `ExtEventLoop`: This uses the `event` pecl extension. It supports the same
+  backends as libevent.
+
+All of the loops support these features:
+
+* File descriptor polling
+* One-off timers
+* Periodic timers
+* Deferred execution of callbacks
+
+## Install
+
+The recommended way to install this library is [through Composer](http://getcomposer.org).
+[New to Composer?](http://getcomposer.org/doc/00-intro.md)
+
+This will install the latest supported version:
+
+```bash
+$ composer require react/event-loop
+```
+
+## Tests
+
+To run the test suite, you first need to clone this repo and then install all
+dependencies [through Composer](http://getcomposer.org):
+
+```bash
+$ composer install
+```
+
+To run the test suite, go to the project root and run:
+
+```bash
+$ php vendor/bin/phpunit
+```

+
+## Usage
+
+This lightweight library consists only of a few simple functions.
+All functions reside under the `React\Promise\Timer` namespace.
+
+The below examples assume you use an import statement similar to this:
+
+```php
+use React\Promise\Timer;
+
+Timer\timeout(…);
+```
+
+Alternatively, you can also refer to them with their fully-qualified name:
+
+```php
+\React\Promise\Timer\timeout(…);
+```
+
+### timeout()
+
+The `timeout(PromiseInterface $promise, $time, LoopInterface $loop)` function
+can be used to *cancel* operations that take *too long*.
+You need to pass in an input `$promise` that represents a pending operation and timeout parameters.
+It returns a new `Promise` with the following resolution behavior:
+
+* If the input `$promise` resolves before `$time` seconds, resolve the resulting promise with its fulfillment value.
+* If the input `$promise` rejects before `$time` seconds, reject the resulting promise with its rejection value.
+* If the input `$promise` does not settle before `$time` seconds, *cancel* the operation and reject the resulting promise with a [`TimeoutException`](#timeoutexception).
+
+Internally, the given `$time` value will be used to start a timer that will
+*cancel* the pending operation once it triggers.
+This implies that if you pass a really small (or negative) value, it will still
+start a timer and will thus trigger at the earliest possible time in the future.
+
+If the input `$promise` is already settled, then the resulting promise will
+resolve or reject immediately without starting a timer at all.
+
+A common use case for handling only resolved values looks like this:
+
+```php
+$promise = accessSomeRemoteResource();
+Timer\timeout($promise, 10.0, $loop)->then(function ($value) {
+    // the operation finished within 10.0 seconds
+});
+```
+
+A more complete example could look like this:
+
+```php
+$promise = accessSomeRemoteResource();
+Timer\timeout($promise, 10.0, $loop)->then(
+    function ($value) {
+        // the operation finished within 10.0 seconds
+    },
+    function ($error) {
+        if ($error instanceof Timer\TimeoutException) {
+            // the operation has failed due to a timeout
+        } else {
+            // the input operation has failed due to some other error
+        }
+    }
+);
+```
+
+Or if you're using [react/promise v2.2.0](https://github.com/reactphp/promise) or up:
+
+```php
+Timer\timeout($promise, 10.0, $loop)
+    ->then(function ($value) {
+        // the operation finished within 10.0 seconds
+    })
+    ->otherwise(function (Timer\TimeoutException $error) {
+        // the operation has failed due to a timeout
+    })
+    ->otherwise(function ($error) {
+        // the input operation has failed due to some other error
+    })
+;
+```
+
+#### Timeout cancellation
+
+As discussed above, the [`timeout()`](#timeout) function will *cancel* the
+underlying operation if it takes *too long*.
+This means that you can be sure the resulting promise will then be rejected
+with a [`TimeoutException`](#timeoutexception).
+
+However, what happens to the underlying input `$promise` is a bit more tricky:
+Once the timer fires, we will try to call
+[`$promise->cancel()`](https://github.com/reactphp/promise#cancellablepromiseinterfacecancel)
+on the input `$promise` which in turn invokes its [cancellation handler](#cancellation-handler).
+
+This means that it's actually up the input `$promise` to handle
+[cancellation support](https://github.com/reactphp/promise#cancellablepromiseinterface).
+
+* A common use case involves cleaning up any resources like open network sockets or
+  file handles or terminating external processes or timers.
+
+* If the given input `$promise` does not support cancellation, then this is a NO-OP.
+  This means that while the resulting promise will still be rejected, the underlying
+  input `$promise` may still be pending and can hence continue consuming resources.
+
+See the following chapter for more details on the cancellation handler.
+
+#### Cancellation handler
+
+For example, an implementation for the above operation could look like this:
+
+```php
+function accessSomeRemoteResource()
+{
+    return new Promise(
+        function ($resolve, $reject) use (&$socket) {
+            // this will be called once the promise is created
+            // a common use case involves opening any resources and eventually resolving
+            $socket = createSocket();
+            $socket->on('data', function ($data) use ($resolve) {
+                $resolve($data);
+            });
+        },
+        function ($resolve, $reject) use (&$socket) {
+            // this will be called once calling `cancel()` on this promise
+            // a common use case involves cleaning any resources and then rejecting
+            $socket->close();
+            $reject(new \RuntimeException('Operation cancelled'));
+        }
+    );
+}
+```
+
+In this example, calling `$promise->cancel()` will invoke the registered cancellation
+handler which then closes the network socket and rejects the `Promise` instance.
+
+If no cancellation handler is passed to the `Promise` constructor, then invoking
+its `cancel()` method it is effectively a NO-OP.
+This means that it may still be pending and can hence continue consuming resources.
+
+For more details on the promise cancellation, please refer to the
+[Promise documentation](https://github.com/reactphp/promise#cancellablepromiseinterface).
+
+#### Input cancellation
+
+Irrespective of the timeout handling, you can also explicitly `cancel()` the
+input `$promise` at any time.
+This means that the `timeout()` handling does not affect cancellation of the
+input `$promise`, as demonstrated in the following example:
+
+```php
+$promise = accessSomeRemoteResource();
+$timeout = Timer\timeout($promise, 10.0, $loop);
+
+$promise->cancel();
+```
+
+The registered [cancellation handler](#cancellation-handler) is responsible for
+handling the `cancel()` call:
+
+* A described above, a common use involves resource cleanup and will then *reject*
+  the `Promise`.
+  If the input `$promise` is being rejected, then the timeout will be aborted
+  and the resulting promise will also be rejected.
+* If the input `$promise` is still pending, then the timout will continue
+  running until the timer expires.
+  The same happens if the input `$promise` does not register a
+  [cancellation handler](#cancellation-handler). 
+
+#### Output cancellation
+
+Similarily, you can also explicitly `cancel()` the resulting promise like this:
+
+```php
+$promise = accessSomeRemoteResource();
+$timeout = Timer\timeout($promise, 10.0, $loop);
+
+$timeout->cancel();
+```
+
+Note how this looks very similar to the above [input cancellation](#input-cancellation)
+example. Accordingly, it also behaves very similar.
+
+Calling `cancel()` on the resulting promise will merely try
+to `cancel()` the input `$promise`.
+This means that we do not take over responsibility of the outcome and it's
+entirely up to the input `$promise` to handle cancellation support.
+
+The registered [cancellation handler](#cancellation-handler) is responsible for
+handling the `cancel()` call:
+
+* As described above, a common use involves resource cleanup and will then *reject*
+  the `Promise`.
+  If the input `$promise` is being rejected, then the timeout will be aborted
+  and the resulting promise will also be rejected.
+* If the input `$promise` is still pending, then the timout will continue
+  running until the timer expires.
+  The same happens if the input `$promise` does not register a
+  [cancellation handler](#cancellation-handler). 
+
+To re-iterate, note that calling `cancel()` on the resulting promise will merely
+try to cancel the input `$promise` only.
+It is then up to the cancellation handler of the input promise to settle the promise.
+If the input promise is still pending when the timeout occurs, then the normal
+[timeout cancellation](#timeout-cancellation) handling will trigger, effectively rejecting
+the output promise with a [`TimeoutException`](#timeoutexception).
+
+This is done for consistency with the [timeout cancellation](#timeout-cancellation)
+handling and also because it is assumed this is often used like this:
+
+```php
+$timeout = Timer\timeout(accessSomeRemoteResource(), 10.0, $loop);
+
+$timeout->cancel();
+```
+
+As described above, this example works as expected and cleans up any resources
+allocated for the input `$promise`.
+
+Note that if the given input `$promise` does not support cancellation, then this
+is a NO-OP.
+This means that while the resulting promise will still be rejected after the
+timeout, the underlying input `$promise` may still be pending and can hence
+continue consuming resources.
+
+#### Collections
+
+If you want to wait for multiple promises to resolve, you can use the normal promise primitives like this:
+
+```php
+$promises = array(
+    accessSomeRemoteResource(),
+    accessSomeRemoteResource(),
+    accessSomeRemoteResource()
+);
+
+$promise = \React\Promise\all($promises);
+
+Timer\timeout($promise, 10, $loop)->then(function ($values) {
+    // *all* promises resolved
+});
+```
+
+The applies to all promise collection primitives alike, i.e. `all()`, `race()`, `any()`, `some()` etc.
+
+For more details on the promise primitives, please refer to the
+[Promise documentation](https://github.com/reactphp/promise#functions).
+
+### resolve()
+
+The `resolve($time, LoopInterface $loop)` function can be used to create a new Promise that
+resolves in `$time` seconds with the `$time` as the fulfillment value.
+
+```php
+Timer\resolve(1.5, $loop)->then(function ($time) {
+    echo 'Thanks for waiting ' . $time . ' seconds' . PHP_EOL;
+});
+```
+
+Internally, the given `$time` value will be used to start a timer that will
+resolve the promise once it triggers.
+This implies that if you pass a really small (or negative) value, it will still
+start a timer and will thus trigger at the earliest possible time in the future.
+
+#### Resolve cancellation
+
+You can explicitly `cancel()` the resulting timer promise at any time:
+
+```php
+$timer = Timer\resolve(2.0, $loop);
+
+$timer->cancel();
+```
+
+This will abort the timer and *reject* with a `RuntimeException`.
+
+### reject()
+
+The `reject($time, LoopInterface $loop)` function can be used to create a new Promise
+which rejects in `$time` seconds with a `TimeoutException`.
+
+```php
+Timer\reject(2.0, $loop)->then(null, function (TimeoutException $e) {
+    echo 'Rejected after ' . $e->getTimeout() . ' seconds ' . PHP_EOL;
+});
+```
+
+Internally, the given `$time` value will be used to start a timer that will
+reject the promise once it triggers.
+This implies that if you pass a really small (or negative) value, it will still
+start a timer and will thus trigger at the earliest possible time in the future.
+
+This function complements the [`resolve()`](#resolve) function
+and can be used as a basic building block for higher-level promise consumers.
+
+#### Reject cancellation
+
+You can explicitly `cancel()` the resulting timer promise at any time:
+
+```php
+$timer = Timer\reject(2.0, $loop);
+
+$timer->cancel();
+```
+
+This will abort the timer and *reject* with a `RuntimeException`.
+
+### TimeoutException
+
+The `TimeoutException` extends PHP's built-in `RuntimeException`.
+
+The `getTimeout()` method can be used to get the timeout value in seconds.

+CHANGELOG for 2.x
+=================
+
+* 2.7.1 (2018-01-07)
+
+    *   Fix: file_exists warning when resolving with long strings.
+        (#130 by @sbesselsen)
+    *   Improve performance by prefixing all global functions calls with \ to skip the look up and resolve process and go straight to the global function.
+        (#133 by @WyriHaximus)
+
+* 2.7.0 (2018-06-13)
+
+    *   Feature: Improve memory consumption for pending promises by using static internal callbacks without binding to self.
+        (#124 by @clue)
+
+* 2.6.0 (2018-06-11)
+
+    *   Feature: Significantly improve memory consumption and performance by only passing resolver args
+        to resolver and canceller if callback requires them. Also use static callbacks without
+        binding to promise, clean up canceller function reference when they are no longer
+        needed and hide resolver and canceller references from call stack on PHP 7+.
+        (#113, #115, #116, #117, #118, #119 and #123 by @clue)
+
+        These changes combined mean that rejecting promises with an `Exception` should
+        no longer cause any internal circular references which could cause some unexpected
+        memory growth in previous versions. By explicitly avoiding and explicitly
+        cleaning up said references, we can avoid relying on PHP's circular garbage collector
+        to kick in which significantly improves performance when rejecting many promises.
+
+    *   Mark legacy progress support / notification API as deprecated
+        (#112 by @clue)
+
+    *   Recommend rejecting promises by throwing an exception
+        (#114 by @jsor)
+
+    *   Improve documentation to properly instantiate LazyPromise
+        (#121 by @holtkamp)
+
+    *   Follower cancellation propagation was originally planned for this release
+        but has been reverted for now and is planned for a future release.
+        (#99 by @jsor and #122 by @clue)
+
+* 2.5.1 (2017-03-25)
+
+    * Fix circular references when resolving with a promise which follows
+      itself (#94).
+
+* 2.5.0 (2016-12-22)
+
+    * Revert automatic cancellation of pending collection promises once the
+      output promise resolves. This was introduced in 42d86b7 (PR #36, released
+      in [v2.3.0](https://github.com/reactphp/promise/releases/tag/v2.3.0)) and
+      was both unintended and backward incompatible.
+
+      If you need automatic cancellation, you can use something like:
+
+      ```php
+      function allAndCancel(array $promises)
+      {
+           return \React\Promise\all($promises)
+               ->always(function() use ($promises) {
+                   foreach ($promises as $promise) {
+                       if ($promise instanceof \React\Promise\CancellablePromiseInterface) {
+                           $promise->cancel();
+                       }
+                   }
+              });
+      }
+      ```
+    * `all()` and `map()` functions now preserve the order of the array (#77).
+    * Fix circular references when resolving a promise with itself (#71).
+
+* 2.4.1 (2016-05-03)
+
+    * Fix `some()` not cancelling pending promises when too much input promises
+      reject (16ff799).
+
+* 2.4.0 (2016-03-31)
+
+    * Support foreign thenables in `resolve()`.
+      Any object that provides a `then()` method is now assimilated to a trusted
+      promise that follows the state of this thenable (#52).
+    * Fix `some()` and `any()` for input arrays containing not enough items
+      (#34).
+
+* 2.3.0 (2016-03-24)
+
+    * Allow cancellation of promises returned by functions working on promise
+      collections (#36).
+    * Handle `\Throwable` in the same way as `\Exception` (#51 by @joshdifabio).
+
+* 2.2.2 (2016-02-26)
+
+    * Fix cancellation handlers called multiple times (#47 by @clue).
+
+* 2.2.1 (2015-07-03)
+
+    * Fix stack error when resolving a promise in its own fulfillment or
+      rejection handlers.
+
+* 2.2.0 (2014-12-30)
+
+    * Introduce new `ExtendedPromiseInterface` implemented by all promises.
+    * Add new `done()` method (part of the `ExtendedPromiseInterface`).
+    * Add new `otherwise()` method (part of the `ExtendedPromiseInterface`).
+    * Add new `always()` method (part of the `ExtendedPromiseInterface`).
+    * Add new `progress()` method (part of the `ExtendedPromiseInterface`).
+    * Rename `Deferred::progress` to `Deferred::notify` to avoid confusion with
+      `ExtendedPromiseInterface::progress` (a `Deferred::progress` alias is
+      still available for backward compatibility)
+    * `resolve()` now always returns a `ExtendedPromiseInterface`.
+
+* 2.1.0 (2014-10-15)
+
+    * Introduce new `CancellablePromiseInterface` implemented by all promises.
+    * Add new `cancel()` method (part of the `CancellablePromiseInterface`).
+
+* 2.0.0 (2013-12-10)
+
+    New major release. The goal is to streamline the API and to make it more
+    compliant with other promise libraries and especially with the new upcoming
+    [ES6 promises specification](https://github.com/domenic/promises-unwrapping/).
+
+    * Add standalone Promise class.
+    * Add new `race()` function.
+    * BC break: Bump minimum PHP version to PHP 5.4.
+    * BC break: Remove `ResolverInterface` and `PromiseInterface` from 
+      `Deferred`.
+    * BC break: Change signature of `PromiseInterface`.
+    * BC break: Remove `When` and `Util` classes and move static methods to
+      functions.
+    * BC break: `FulfilledPromise` and `RejectedPromise` now throw an exception
+      when initialized with a promise instead of a value/reason.
+    * BC break: `Deferred::resolve()` and `Deferred::reject()` no longer return
+      a promise.

+Introduction
+------------
+
+Promise is a library implementing
+[CommonJS Promises/A](http://wiki.commonjs.org/wiki/Promises/A) for PHP.
+
+It also provides several other useful promise-related concepts, such as joining
+multiple promises and mapping and reducing collections of promises.
+
+If you've never heard about promises before,
+[read this first](https://gist.github.com/3889970).
+
+Concepts
+--------
+
+### Deferred
+
+A **Deferred** represents a computation or unit of work that may not have
+completed yet. Typically (but not always), that computation will be something
+that executes asynchronously and completes at some point in the future.
+
+### Promise
+
+While a deferred represents the computation itself, a **Promise** represents
+the result of that computation. Thus, each deferred has a promise that acts as
+a placeholder for its actual result.
+
+API
+---
+
+### Deferred
+
+A deferred represents an operation whose resolution is pending. It has separate
+promise and resolver parts.
+
+```php
+$deferred = new React\Promise\Deferred();
+
+$promise = $deferred->promise();
+
+$deferred->resolve(mixed $value = null);
+$deferred->reject(mixed $reason = null);
+$deferred->notify(mixed $update = null);
+```
+
+The `promise` method returns the promise of the deferred.
+
+The `resolve` and `reject` methods control the state of the deferred.
+
+The deprecated `notify` method is for progress notification.
+
+The constructor of the `Deferred` accepts an optional `$canceller` argument.
+See [Promise](#promise-2) for more information.
+
+#### Deferred::promise()
+
+```php
+$promise = $deferred->promise();
+```
+
+Returns the promise of the deferred, which you can hand out to others while
+keeping the authority to modify its state to yourself.
+
+#### Deferred::resolve()
+
+```php
+$deferred->resolve(mixed $value = null);
+```
+
+Resolves the promise returned by `promise()`. All consumers are notified by
+having `$onFulfilled` (which they registered via `$promise->then()`) called with
+`$value`.
+
+If `$value` itself is a promise, the promise will transition to the state of
+this promise once it is resolved.
+
+#### Deferred::reject()
+
+```php
+$deferred->reject(mixed $reason = null);
+```
+
+Rejects the promise returned by `promise()`, signalling that the deferred's
+computation failed.
+All consumers are notified by having `$onRejected` (which they registered via
+`$promise->then()`) called with `$reason`.
+
+If `$reason` itself is a promise, the promise will be rejected with the outcome
+of this promise regardless whether it fulfills or rejects.
+
+#### Deferred::notify()
+
+> Deprecated in v2.6.0: Progress support is deprecated and should not be used anymore.
+
+```php
+$deferred->notify(mixed $update = null);
+```
+
+Triggers progress notifications, to indicate to consumers that the computation
+is making progress toward its result.
+
+All consumers are notified by having `$onProgress` (which they registered via
+`$promise->then()`) called with `$update`.
+
+### PromiseInterface
+
+The promise interface provides the common interface for all promise
+implementations.
+
+A promise represents an eventual outcome, which is either fulfillment (success)
+and an associated value, or rejection (failure) and an associated reason.
+
+Once in the fulfilled or rejected state, a promise becomes immutable.
+Neither its state nor its result (or error) can be modified.
+
+#### Implementations
+
+* [Promise](#promise-2)
+* [FulfilledPromise](#fulfilledpromise)
+* [RejectedPromise](#rejectedpromise)
+* [LazyPromise](#lazypromise)
+
+#### PromiseInterface::then()
+
+```php
+$transformedPromise = $promise->then(callable $onFulfilled = null, callable $onRejected = null, callable $onProgress = null);
+```
+
+Transforms a promise's value by applying a function to the promise's fulfillment
+or rejection value. Returns a new promise for the transformed result.
+
+The `then()` method registers new fulfilled, rejection and progress handlers
+with a promise (all parameters are optional):
+
+  * `$onFulfilled` will be invoked once the promise is fulfilled and passed
+    the result as the first argument.
+  * `$onRejected` will be invoked once the promise is rejected and passed the
+    reason as the first argument.
+  * `$onProgress` (deprecated) will be invoked whenever the producer of the promise
+    triggers progress notifications and passed a single argument (whatever it
+    wants) to indicate progress.
+
+It returns a new promise that will fulfill with the return value of either
+`$onFulfilled` or `$onRejected`, whichever is called, or will reject with
+the thrown exception if either throws.
+
+A promise makes the following guarantees about handlers registered in
+the same call to `then()`:
+
+  1. Only one of `$onFulfilled` or `$onRejected` will be called,
+     never both.
+  2. `$onFulfilled` and `$onRejected` will never be called more
+     than once.
+  3. `$onProgress` (deprecated) may be called multiple times.

+
+### ExtendedPromiseInterface
+
+The ExtendedPromiseInterface extends the PromiseInterface with useful shortcut
+and utility methods which are not part of the Promises/A specification.
+
+#### Implementations
+
+* [Promise](#promise-1)
+* [FulfilledPromise](#fulfilledpromise)
+* [RejectedPromise](#rejectedpromise)
+* [LazyPromise](#lazypromise)
+
+#### ExtendedPromiseInterface::done()
+
+```php
+$promise->done(callable $onFulfilled = null, callable $onRejected = null, callable $onProgress = null);
+```
+
+Consumes the promise's ultimate value if the promise fulfills, or handles the
+ultimate error.
+
+It will cause a fatal error if either `$onFulfilled` or `$onRejected` throw or
+return a rejected promise.
+
+Since the purpose of `done()` is consumption rather than transformation,
+`done()` always returns `null`.
+
+#### See also
+
+* [PromiseInterface::then()](#promiseinterfacethen)
+* [done() vs. then()](#done-vs-then)
+
+#### ExtendedPromiseInterface::otherwise()
+
+```php
+$promise->otherwise(callable $onRejected);
+```
+
+Registers a rejection handler for promise. It is a shortcut for:
+
+```php
+$promise->then(null, $onRejected);
+```
+
+Additionally, you can type hint the `$reason` argument of `$onRejected` to catch
+only specific errors.
+
+```php
+$promise
+    ->otherwise(function (\RuntimeException $reason) {
+        // Only catch \RuntimeException instances
+        // All other types of errors will propagate automatically
+    })
+    ->otherwise(function ($reason) {
+        // Catch other errors
+    )};
+```
+
+#### ExtendedPromiseInterface::always()
+
+```php
+$newPromise = $promise->always(callable $onFulfilledOrRejected);
+```
+
+Allows you to execute "cleanup" type tasks in a promise chain.
+
+It arranges for `$onFulfilledOrRejected` to be called, with no arguments,
+when the promise is either fulfilled or rejected.
+
+* If `$promise` fulfills, and `$onFulfilledOrRejected` returns successfully,
+  `$newPromise` will fulfill with the same value as `$promise`.
+* If `$promise` fulfills, and `$onFulfilledOrRejected` throws or returns a
+  rejected promise, `$newPromise` will reject with the thrown exception or
+  rejected promise's reason.
+* If `$promise` rejects, and `$onFulfilledOrRejected` returns successfully,
+  `$newPromise` will reject with the same reason as `$promise`.
+* If `$promise` rejects, and `$onFulfilledOrRejected` throws or returns a
+  rejected promise, `$newPromise` will reject with the thrown exception or
+  rejected promise's reason.
+
+`always()` behaves similarly to the synchronous finally statement. When combined
+with `otherwise()`, `always()` allows you to write code that is similar to the familiar
+synchronous catch/finally pair.
+
+Consider the following synchronous code:
+
+```php
+try {
+  return doSomething();
+} catch(\Exception $e) {
+    return handleError($e);
+} finally {
+    cleanup();
+}
+```
+
+Similar asynchronous code (with `doSomething()` that returns a promise) can be
+written:
+
+```php
+return doSomething()
+    ->otherwise('handleError')
+    ->always('cleanup');
+```
+
+#### ExtendedPromiseInterface::progress()
+
+> Deprecated in v2.6.0: Progress support is deprecated and should not be used anymore.
+
+```php
+$promise->progress(callable $onProgress);
+```
+
+Registers a handler for progress updates from promise. It is a shortcut for:
+
+```php
+$promise->then(null, null, $onProgress);
+```
+
+### CancellablePromiseInterface
+
+A cancellable promise provides a mechanism for consumers to notify the creator
+of the promise that they are not longer interested in the result of an
+operation.
+
+#### CancellablePromiseInterface::cancel()
+
+``` php
+$promise->cancel();
+```
+
+The `cancel()` method notifies the creator of the promise that there is no
+further interest in the results of the operation.
+
+Once a promise is settled (either fulfilled or rejected), calling `cancel()` on
+a promise has no effect.
+
+#### Implementations
+
+* [Promise](#promise-1)
+* [FulfilledPromise](#fulfilledpromise)
+* [RejectedPromise](#rejectedpromise)
+* [LazyPromise](#lazypromise)
+
+### Promise
+
+Creates a promise whose state is controlled by the functions passed to
+`$resolver`.
+
+```php
+$resolver = function (callable $resolve, callable $reject, callable $notify) {
+    // Do some work, possibly asynchronously, and then
+    // resolve or reject. You can notify of progress events (deprecated)
+    // along the way if you want/need.
+
+    $resolve($awesomeResult);
+    // or throw new Exception('Promise rejected');
+    // or $resolve($anotherPromise);
+    // or $reject($nastyError);
+    // or $notify($progressNotification);
+};
+
+$canceller = function () {
+    // Cancel/abort any running operations like network connections, streams etc.
+
+    // Reject promise by throwing an exception
+    throw new Exception('Promise cancelled');
+};
+
+$promise = new React\Promise\Promise($resolver, $canceller);
+```
+
+The promise constructor receives a resolver function and an optional canceller
+function which both will be called with 3 arguments:
+
+  * `$resolve($value)` - Primary function that seals the fate of the
+    returned promise. Accepts either a non-promise value, or another promise.
+    When called with a non-promise value, fulfills promise with that value.
+    When called with another promise, e.g. `$resolve($otherPromise)`, promise's
+    fate will be equivalent to that of `$otherPromise`.
+  * `$reject($reason)` - Function that rejects the promise. It is recommended to
+    just throw an exception instead of using `$reject()`.
+  * `$notify($update)` - Deprecated function that issues progress events for the promise.
+
+If the resolver or canceller throw an exception, the promise will be rejected
+with that thrown exception as the rejection reason.
+
+The resolver function will be called immediately, the canceller function only
+once all consumers called the `cancel()` method of the promise.
+
+### FulfilledPromise
+
+Creates a already fulfilled promise.
+
+```php
+$promise = React\Promise\FulfilledPromise($value);
+```
+
+Note, that `$value` **cannot** be a promise. It's recommended to use
+[resolve()](#resolve) for creating resolved promises.
+
+### RejectedPromise
+
+Creates a already rejected promise.
+
+```php
+$promise = React\Promise\RejectedPromise($reason);
+```
+
+Note, that `$reason` **cannot** be a promise. It's recommended to use
+[reject()](#reject) for creating rejected promises.
+
+### LazyPromise
+
+Creates a promise which will be lazily initialized by `$factory` once a consumer
+calls the `then()` method.
+
+```php
+$factory = function () {
+    $deferred = new React\Promise\Deferred();
+
+    // Do some heavy stuff here and resolve the deferred once completed
+
+    return $deferred->promise();
+};
+
+$promise = new React\Promise\LazyPromise($factory);
+
+// $factory will only be executed once we call then()
+$promise->then(function ($value) {
+});
+```
+
+### Functions
+
+Useful functions for creating, joining, mapping and reducing collections of
+promises.
+
+All functions working on promise collections (like `all()`, `race()`, `some()`
+etc.) support cancellation. This means, if you call `cancel()` on the returned
+promise, all promises in the collection are cancelled. If the collection itself
+is a promise which resolves to an array, this promise is also cancelled.
+
+#### resolve()
+
+```php
+$promise = React\Promise\resolve(mixed $promiseOrValue);
+```
+
+Creates a promise for the supplied `$promiseOrValue`.
+
+If `$promiseOrValue` is a value, it will be the resolution value of the
+returned promise.
+
+If `$promiseOrValue` is a thenable (any object that provides a `then()` method),
+a trusted promise that follows the state of the thenable is returned.
+
+If `$promiseOrValue` is a promise, it will be returned as is.
+
+Note: The promise returned is always a promise implementing
+[ExtendedPromiseInterface](#extendedpromiseinterface). If you pass in a custom
+promise which only implements [PromiseInterface](#promiseinterface), this
+promise will be assimilated to a extended promise following `$promiseOrValue`.
+
+#### reject()
+
+```php
+$promise = React\Promise\reject(mixed $promiseOrValue);
+```
+
+Creates a rejected promise for the supplied `$promiseOrValue`.
+
+If `$promiseOrValue` is a value, it will be the rejection value of the
+returned promise.
+
+If `$promiseOrValue` is a promise, its completion value will be the rejected
+value of the returned promise.
+
+This can be useful in situations where you need to reject a promise without
+throwing an exception. For example, it allows you to propagate a rejection with
+the value of another promise.
+
+#### all()
+
+```php
+$promise = React\Promise\all(array|React\Promise\PromiseInterface $promisesOrValues);
+```
+
+Returns a promise that will resolve only once all the items in
+`$promisesOrValues` have resolved. The resolution value of the returned promise
+will be an array containing the resolution values of each of the items in
+`$promisesOrValues`.
+
+#### race()
+
+```php
+$promise = React\Promise\race(array|React\Promise\PromiseInterface $promisesOrValues);
+```
+
+Initiates a competitive race that allows one winner. Returns a promise which is
+resolved in the same way the first settled promise resolves.
+
+#### any()
+
+```php
+$promise = React\Promise\any(array|React\Promise\PromiseInterface $promisesOrValues);
+```
+
+Returns a promise that will resolve when any one of the items in
+`$promisesOrValues` resolves. The resolution value of the returned promise
+will be the resolution value of the triggering item.
+
+The returned promise will only reject if *all* items in `$promisesOrValues` are
+rejected. The rejection value will be an array of all rejection reasons.
+
+The returned promise will also reject with a `React\Promise\Exception\LengthException`
+if `$promisesOrValues` contains 0 items.
+
+#### some()
+
+```php
+$promise = React\Promise\some(array|React\Promise\PromiseInterface $promisesOrValues, integer $howMany);
+```
+
+Returns a promise that will resolve when `$howMany` of the supplied items in
+`$promisesOrValues` resolve. The resolution value of the returned promise
+will be an array of length `$howMany` containing the resolution values of the
+triggering items.
+
+The returned promise will reject if it becomes impossible for `$howMany` items
+to resolve (that is, when `(count($promisesOrValues) - $howMany) + 1` items
+reject). The rejection value will be an array of
+`(count($promisesOrValues) - $howMany) + 1` rejection reasons.
+
+The returned promise will also reject with a `React\Promise\Exception\LengthException`
+if `$promisesOrValues` contains less items than `$howMany`.
+
+#### map()
+
+```php
+$promise = React\Promise\map(array|React\Promise\PromiseInterface $promisesOrValues, callable $mapFunc);
+```
+
+Traditional map function, similar to `array_map()`, but allows input to contain
+promises and/or values, and `$mapFunc` may return either a value or a promise.
+
+The map function receives each item as argument, where item is a fully resolved
+value of a promise or value in `$promisesOrValues`.
+
+#### reduce()
+
+```php
+$promise = React\Promise\reduce(array|React\Promise\PromiseInterface $promisesOrValues, callable $reduceFunc , $initialValue = null);
+```
+
+Traditional reduce function, similar to `array_reduce()`, but input may contain
+promises and/or values, and `$reduceFunc` may return either a value or a
+promise, *and* `$initialValue` may be a promise or a value for the starting
+value.
+
+### PromisorInterface
+
+The `React\Promise\PromisorInterface` provides a common interface for objects
+that provide a promise. `React\Promise\Deferred` implements it, but since it
+is part of the public API anyone can implement it.
+
+Examples
+--------
+
+### How to use Deferred
+
+```php
+function getAwesomeResultPromise()
+{
+    $deferred = new React\Promise\Deferred();
+
+    // Execute a Node.js-style function using the callback pattern
+    computeAwesomeResultAsynchronously(function ($error, $result) use ($deferred) {
+        if ($error) {
+            $deferred->reject($error);
+        } else {
+            $deferred->resolve($result);
+        }
+    });
+
+    // Return the promise
+    return $deferred->promise();
+}
+
+getAwesomeResultPromise()
+    ->then(
+        function ($value) {
+            // Deferred resolved, do something with $value
+        },
+        function ($reason) {
+            // Deferred rejected, do something with $reason
+        },
+        function ($update) {
+            // Progress notification triggered, do something with $update
+        }
+    );
+```
+
+### How promise forwarding works
+
+A few simple examples to show how the mechanics of Promises/A forwarding works.
+These examples are contrived, of course, and in real usage, promise chains will
+typically be spread across several function calls, or even several levels of
+your application architecture.
+
+#### Resolution forwarding
+
+Resolved promises forward resolution values to the next promise.
+The first promise, `$deferred->promise()`, will resolve with the value passed
+to `$deferred->resolve()` below.
+
+Each call to `then()` returns a new promise that will resolve with the return
+value of the previous handler. This creates a promise "pipeline".
+
+```php
+$deferred = new React\Promise\Deferred();
+
+$deferred->promise()
+    ->then(function ($x) {
+        // $x will be the value passed to $deferred->resolve() below
+        // and returns a *new promise* for $x + 1
+        return $x + 1;
+    })
+    ->then(function ($x) {
+        // $x === 2
+        // This handler receives the return value of the
+        // previous handler.
+        return $x + 1;
+    })
+    ->then(function ($x) {
+        // $x === 3
+        // This handler receives the return value of the
+        // previous handler.
+        return $x + 1;
+    })
+    ->then(function ($x) {
+        // $x === 4
+        // This handler receives the return value of the
+        // previous handler.
+        echo 'Resolve ' . $x;
+    });
+
+$deferred->resolve(1); // Prints "Resolve 4"
+```
+
+#### Rejection forwarding
+
+Rejected promises behave similarly, and also work similarly to try/catch:
+When you catch an exception, you must rethrow for it to propagate.
+
+Similarly, when you handle a rejected promise, to propagate the rejection,
+"rethrow" it by either returning a rejected promise, or actually throwing
+(since promise translates thrown exceptions into rejections)
+
+```php
+$deferred = new React\Promise\Deferred();
+
+$deferred->promise()
+    ->then(function ($x) {
+        throw new \Exception($x + 1);
+    })
+    ->otherwise(function (\Exception $x) {
+        // Propagate the rejection
+        throw $x;
+    })
+    ->otherwise(function (\Exception $x) {
+        // Can also propagate by returning another rejection
+        return React\Promise\reject(
+            new \Exception($x->getMessage() + 1)
+        );
+    })
+    ->otherwise(function ($x) {
+        echo 'Reject ' . $x->getMessage(); // 3
+    });
+
+$deferred->resolve(1);  // Prints "Reject 3"
+```
+
+#### Mixed resolution and rejection forwarding
+
+Just like try/catch, you can choose to propagate or not. Mixing resolutions and
+rejections will still forward handler results in a predictable way.
+
+```php
+$deferred = new React\Promise\Deferred();
+
+$deferred->promise()
+    ->then(function ($x) {
+        return $x + 1;
+    })
+    ->then(function ($x) {
+        throw new \Exception($x + 1);
+    })
+    ->otherwise(function (\Exception $x) {
+        // Handle the rejection, and don't propagate.
+        // This is like catch without a rethrow
+        return $x->getMessage() + 1;
+    })
+    ->then(function ($x) {
+        echo 'Mixed ' . $x; // 4
+    });
+
+$deferred->resolve(1);  // Prints "Mixed 4"
+```
+
+#### Progress event forwarding
+
+> Deprecated in v2.6.0: Progress support is deprecated and should not be used anymore.
+
+In the same way as resolution and rejection handlers, your progress handler
+**MUST** return a progress event to be propagated to the next link in the chain.
+If you return nothing, `null` will be propagated.
+
+Also in the same way as resolutions and rejections, if you don't register a
+progress handler, the update will be propagated through.
+
+If your progress handler throws an exception, the exception will be propagated
+to the next link in the chain. The best thing to do is to ensure your progress
+handlers do not throw exceptions.
+
+This gives you the opportunity to transform progress events at each step in the
+chain so that they are meaningful to the next step. It also allows you to choose
+not to transform them, and simply let them propagate untransformed, by not
+registering a progress handler.
+
+```php
+$deferred = new React\Promise\Deferred();
+
+$deferred->promise()
+    ->progress(function ($update) {
+        return $update + 1;

+```
+
+### done() vs. then()
+
+The golden rule is:
+
+    Either return your promise, or call done() on it.
+
+At a first glance, `then()` and `done()` seem very similar. However, there are
+important distinctions.
+
+The intent of `then()` is to transform a promise's value and to pass or return
+a new promise for the transformed value along to other parts of your code.
+
+The intent of `done()` is to consume a promise's value, transferring
+responsibility for the value to your code.
+
+In addition to transforming a value, `then()` allows you to recover from, or
+propagate intermediate errors. Any errors that are not handled will be caught
+by the promise machinery and used to reject the promise returned by `then()`.
+
+Calling `done()` transfers all responsibility for errors to your code. If an
+error (either a thrown exception or returned rejection) escapes the
+`$onFulfilled` or `$onRejected` callbacks you provide to done, it will be
+rethrown in an uncatchable way causing a fatal error.
+
+```php
+function getJsonResult()
+{
+    return queryApi()
+        ->then(
+            // Transform API results to an object
+            function ($jsonResultString) {
+                return json_decode($jsonResultString);
+            },
+            // Transform API errors to an exception
+            function ($jsonErrorString) {
+                $object = json_decode($jsonErrorString);
+                throw new ApiErrorException($object->errorMessage);
+            }
+        );
+}
+
+// Here we provide no rejection handler. If the promise returned has been
+// rejected, the ApiErrorException will be thrown
+getJsonResult()
+    ->done(
+        // Consume transformed object
+        function ($jsonResultObject) {
+            // Do something with $jsonResultObject
+        }
+    );
+
+// Here we provide a rejection handler which will either throw while debugging
+// or log the exception
+getJsonResult()
+    ->done(
+        function ($jsonResultObject) {
+            // Do something with $jsonResultObject
+        },
+        function (ApiErrorException $exception) {
+            if (isDebug()) {
+                throw $exception;
+            } else {
+                logException($exception);
+            }
+        }
+    );
+```
+
+Note that if a rejection value is not an instance of `\Exception`, it will be
+wrapped in an exception of the type `React\Promise\UnhandledRejectionException`.
+
+You can get the original rejection reason by calling `$exception->getReason()`.
+
+Install
+-------
+
+The recommended way to install this library is [through Composer](https://getcomposer.org).
+[New to Composer?](https://getcomposer.org/doc/00-intro.md)
+
+This project follows [SemVer](https://semver.org/).
+This will install the latest supported version:

+# Changelog
+
+## 0.8.12 (2018-06-11)
+
+*   Feature: Improve memory consumption for failed and cancelled connection attempts.
+    (#161 by @clue)
+
+*   Improve test suite to fix Travis config to test against legacy PHP 5.3 again.
+    (#162 by @clue)
+
+## 0.8.11 (2018-04-24)
+
+*   Feature: Improve memory consumption for cancelled connection attempts and
+    simplify skipping DNS lookup when connecting to IP addresses.
+    (#159 and #160 by @clue)
+
+## 0.8.10 (2018-02-28)
+
+*   Feature: Update DNS dependency to support loading system default DNS
+    nameserver config on all supported platforms
+    (`/etc/resolv.conf` on Unix/Linux/Mac/Docker/WSL and WMIC on Windows)
+    (#152 by @clue)
+
+    This means that connecting to hosts that are managed by a local DNS server,
+    such as a corporate DNS server or when using Docker containers, will now
+    work as expected across all platforms with no changes required:
+
+    ```php
+    $connector = new Connector($loop);
+    $connector->connect('intranet.example:80')->then(function ($connection) {
+        // …
+    });
+    ```
+
+## 0.8.9 (2018-01-18)
+
+*   Feature: Support explicitly choosing TLS version to negotiate with remote side
+    by respecting `crypto_method` context parameter for all classes.
+    (#149 by @clue)
+
+    By default, all connector and server classes support TLSv1.0+ and exclude
+    support for legacy SSLv2/SSLv3. As of PHP 5.6+ you can also explicitly
+    choose the TLS version you want to negotiate with the remote side:
+
+    ```php
+    // new: now supports 'crypto_method` context parameter for all classes
+    $connector = new Connector($loop, array(
+        'tls' => array(
+            'crypto_method' => STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT
+        )
+    ));
+    ```
+
+*   Minor internal clean up to unify class imports
+    (#148 by @clue)
+
+## 0.8.8 (2018-01-06)
+
+*   Improve test suite by adding test group to skip integration tests relying on
+    internet connection and fix minor documentation typo.
+    (#146 by @clue and #145 by @cn007b)
+
+## 0.8.7 (2017-12-24)
+
+*   Fix: Fix closing socket resource before removing from loop
+    (#141 by @clue)
+
+    This fixes the root cause of an uncaught `Exception` that only manifested
+    itself after the recent Stream v0.7.4 component update and only if you're
+    using `ext-event` (`ExtEventLoop`).
+
+*   Improve test suite by testing against PHP 7.2
+    (#140 by @carusogabriel)
+
+## 0.8.6 (2017-11-18)
+
+*   Feature: Add Unix domain socket (UDS) support to `Server` with `unix://` URI scheme
+    and add advanced `UnixServer` class.
+    (#120 by @andig)
+
+    ```php
+    // new: Server now supports "unix://" scheme
+    $server = new Server('unix:///tmp/server.sock', $loop);
+
+    // new: advanced usage
+    $server = new UnixServer('/tmp/server.sock', $loop);
+    ```
+
+*   Restructure examples to ease getting started
+    (#136 by @clue)
+
+*   Improve test suite by adding forward compatibility with PHPUnit 6 and
+    ignore Mac OS X test failures for now until Travis tests work again
+    (#133 by @gabriel-caruso and #134 by @clue)
+
+## 0.8.5 (2017-10-23)
+
+*   Fix: Work around PHP bug with Unix domain socket (UDS) paths for Mac OS X
+    (#123 by @andig)
+
+*   Fix: Fix `SecureServer` to return `null` URI if server socket is already closed
+    (#129 by @clue)
+
+*   Improve test suite by adding forward compatibility with PHPUnit v5 and
+    forward compatibility with upcoming EventLoop releases in tests and
+    test Mac OS X on Travis
+    (#122 by @andig and #125, #127 and #130 by @clue)
+
+*   Readme improvements
+    (#118 by @jsor)
+
+## 0.8.4 (2017-09-16)
+
+*   Feature: Add `FixedUriConnector` decorator to use fixed, preconfigured URI instead
+    (#117 by @clue)
+
+    This can be useful for consumers that do not support certain URIs, such as
+    when you want to explicitly connect to a Unix domain socket (UDS) path
+    instead of connecting to a default address assumed by an higher-level API:
+
+    ```php
+    $connector = new FixedUriConnector(
+        'unix:///var/run/docker.sock',
+        new UnixConnector($loop)
+    );
+
+    // destination will be ignored, actually connects to Unix domain socket
+    $promise = $connector->connect('localhost:80');
+    ```
+
+## 0.8.3 (2017-09-08)
+
+*   Feature: Reduce memory consumption for failed connections
+    (#113 by @valga)
+
+*   Fix: Work around write chunk size for TLS streams for PHP < 7.1.14
+    (#114 by @clue)
+
+## 0.8.2 (2017-08-25)
+
+*   Feature: Update DNS dependency to support hosts file on all platforms
+    (#112 by @clue)
+
+    This means that connecting to hosts such as `localhost` will now work as
+    expected across all platforms with no changes required:
+
+    ```php
+    $connector = new Connector($loop);
+    $connector->connect('localhost:8080')->then(function ($connection) {
+        // …
+    });
+    ```
+
+## 0.8.1 (2017-08-15)
+
+* Feature: Forward compatibility with upcoming EventLoop v1.0 and v0.5 and
+  target evenement 3.0 a long side 2.0 and 1.0
+  (#104 by @clue and #111 by @WyriHaximus)
+
+* Improve test suite by locking Travis distro so new defaults will not break the build and
+  fix HHVM build for now again and ignore future HHVM build errors
+  (#109 and #110 by @clue)
+
+* Minor documentation fixes
+  (#103 by @christiaan and #108 by @hansott)
+
+## 0.8.0 (2017-05-09)
+
+* Feature: New `Server` class now acts as a facade for existing server classes
+  and renamed old `Server` to `TcpServer` for advanced usage.
+  (#96 and #97 by @clue)
+
+  The `Server` class is now the main class in this package that implements the
+  `ServerInterface` and allows you to accept incoming streaming connections,
+  such as plaintext TCP/IP or secure TLS connection streams.
+
+  > This is not a BC break and consumer code does not have to be updated.
+
+* Feature / BC break: All addresses are now URIs that include the URI scheme
+  (#98 by @clue)
+
+  ```diff
+  - $parts = parse_url('tcp://' . $conn->getRemoteAddress());
+  + $parts = parse_url($conn->getRemoteAddress());
+  ```
+
+* Fix: Fix `unix://` addresses for Unix domain socket (UDS) paths
+  (#100 by @clue)
+
+* Feature: Forward compatibility with Stream v1.0 and v0.7
+  (#99 by @clue)
+
+## 0.7.2 (2017-04-24)
+
+* Fix: Work around latest PHP 7.0.18 and 7.1.4 no longer accepting full URIs
+  (#94 by @clue)
+
+## 0.7.1 (2017-04-10)
+
+* Fix: Ignore HHVM errors when closing connection that is already closing
+  (#91 by @clue)
+
+## 0.7.0 (2017-04-10)
+
+* Feature: Merge SocketClient component into this component
+  (#87 by @clue)
+
+  This means that this package now provides async, streaming plaintext TCP/IP
+  and secure TLS socket server and client connections for ReactPHP.
+
+  ```
+  $connector = new React\Socket\Connector($loop);
+  $connector->connect('google.com:80')->then(function (ConnectionInterface $conn) {
+      $connection->write('…');
+  });
+  ```
+
+  Accordingly, the `ConnectionInterface` is now used to represent both incoming
+  server side connections as well as outgoing client side connections.
+
+  If you've previously used the SocketClient component to establish outgoing
+  client connections, upgrading should take no longer than a few minutes.
+  All classes have been merged as-is from the latest `v0.7.0` release with no
+  other changes, so you can simply update your code to use the updated namespace
+  like this:
+
+  ```php
+  // old from SocketClient component and namespace
+  $connector = new React\SocketClient\Connector($loop);
+  $connector->connect('google.com:80')->then(function (ConnectionInterface $conn) {
+      $connection->write('…');
+  });
+
+  // new
+  $connector = new React\Socket\Connector($loop);
+  $connector->connect('google.com:80')->then(function (ConnectionInterface $conn) {
+      $connection->write('…');
+  });
+  ```
+
+## 0.6.0 (2017-04-04)
+
+* Feature: Add `LimitingServer` to limit and keep track of open connections
+  (#86 by @clue)
+
+  ```php
+  $server = new Server(0, $loop);
+  $server = new LimitingServer($server, 100);
+
+  $server->on('connection', function (ConnectionInterface $connection) {
+      $connection->write('hello there!' . PHP_EOL);
+      …
+  });
+  ```
+
+* Feature / BC break: Add `pause()` and `resume()` methods to limit active
+  connections
+  (#84 by @clue)
+
+  ```php
+  $server = new Server(0, $loop);
+  $server->pause();
+
+  $loop->addTimer(1.0, function() use ($server) {
+      $server->resume();
+  });
+  ```
+
+## 0.5.1 (2017-03-09)
+
+* Feature: Forward compatibility with Stream v0.5 and upcoming v0.6
+  (#79 by @clue)
+
+## 0.5.0 (2017-02-14)
+
+* Feature / BC break: Replace `listen()` call with URIs passed to constructor
+  and reject listening on hostnames with `InvalidArgumentException`
+  and replace `ConnectionException` with `RuntimeException` for consistency
+  (#61, #66 and #72 by @clue)
+
+  ```php
+  // old
+  $server = new Server($loop);
+  $server->listen(8080);
+
+  // new
+  $server = new Server(8080, $loop);
+  ```
+
+  Similarly, you can now pass a full listening URI to the constructor to change
+  the listening host:
+
+  ```php
+  // old
+  $server = new Server($loop);
+  $server->listen(8080, '127.0.0.1');
+
+  // new
+  $server = new Server('127.0.0.1:8080', $loop);
+  ```
+
+  Trying to start listening on (DNS) host names will now throw an
+  `InvalidArgumentException`, use IP addresses instead:
+
+  ```php
+  // old
+  $server = new Server($loop);
+  $server->listen(8080, 'localhost');
+
+  // new
+  $server = new Server('127.0.0.1:8080', $loop);
+  ```
+
+  If trying to listen fails (such as if port is already in use or port below
+  1024 may require root access etc.), it will now throw a `RuntimeException`,
+  the `ConnectionException` class has been removed:
+
+  ```php
+  // old: throws React\Socket\ConnectionException
+  $server = new Server($loop);
+  $server->listen(80);
+
+  // new: throws RuntimeException
+  $server = new Server(80, $loop);
+  ```
+
+* Feature / BC break: Rename `shutdown()` to `close()` for consistency throughout React
+  (#62 by @clue)
+
+  ```php
+  // old
+  $server->shutdown();
+
+  // new
+  $server->close();
+  ```
+
+* Feature / BC break: Replace `getPort()` with `getAddress()`
+  (#67 by @clue)
+
+  ```php
+  // old
+  echo $server->getPort(); // 8080
+
+  // new
+  echo $server->getAddress(); // 127.0.0.1:8080
+  ```
+
+* Feature / BC break: `getRemoteAddress()` returns full address instead of only IP
+  (#65 by @clue)
+
+  ```php
+  // old
+  echo $connection->getRemoteAddress(); // 192.168.0.1
+
+  // new
+  echo $connection->getRemoteAddress(); // 192.168.0.1:51743
+  ```
+  
+* Feature / BC break: Add `getLocalAddress()` method
+  (#68 by @clue)
+
+  ```php
+  echo $connection->getLocalAddress(); // 127.0.0.1:8080
+  ```
+
+* BC break: The `Server` and `SecureServer` class are now marked `final`
+  and you can no longer `extend` them
+  (which was never documented or recommended anyway).
+  Public properties and event handlers are now internal only.
+  Please use composition instead of extension.
+  (#71, #70 and #69 by @clue)
+
+## 0.4.6 (2017-01-26)
+
+* Feature: Support socket context options passed to `Server`
+  (#64 by @clue)

+# Socket
+
+[![Build Status](https://travis-ci.org/reactphp/socket.svg?branch=master)](https://travis-ci.org/reactphp/socket)
+
+Async, streaming plaintext TCP/IP and secure TLS socket server and client
+connections for [ReactPHP](https://reactphp.org/).
+
+The socket library provides re-usable interfaces for a socket-layer
+server and client based on the [`EventLoop`](https://github.com/reactphp/event-loop)
+and [`Stream`](https://github.com/reactphp/stream) components.
+Its server component allows you to build networking servers that accept incoming
+connections from networking clients (such as an HTTP server).
+Its client component allows you to build networking clients that establish
+outgoing connections to networking servers (such as an HTTP or database client).
+This library provides async, streaming means for all of this, so you can
+handle multiple concurrent connections without blocking.

+## Quickstart example
+
+Here is a server that closes the connection if you send it anything:
+
+```php
+$loop = React\EventLoop\Factory::create();
+$socket = new React\Socket\Server('127.0.0.1:8080', $loop);
+
+$socket->on('connection', function (ConnectionInterface $conn) {
+    $conn->write("Hello " . $conn->getRemoteAddress() . "!\n");
+    $conn->write("Welcome to this amazing server!\n");
+    $conn->write("Here's a tip: don't say anything.\n");
+
+    $conn->on('data', function ($data) use ($conn) {
+        $conn->close();
+    });
+});
+
+$loop->run();
+```
+
+See also the [examples](examples).
+
+Here's a client that outputs the output of said server and then attempts to
+send it a string:
+
+```php
+$loop = React\EventLoop\Factory::create();
+$connector = new React\Socket\Connector($loop);
+
+$connector->connect('127.0.0.1:8080')->then(function (ConnectionInterface $conn) use ($loop) {
+    $conn->pipe(new React\Stream\WritableResourceStream(STDOUT, $loop));
+    $conn->write("Hello World!\n");
+});
+
+$loop->run();
+```
+
+## Connection usage
+
+### ConnectionInterface
+
+The `ConnectionInterface` is used to represent any incoming and outgoing
+connection, such as a normal TCP/IP connection.
+
+An incoming or outgoing connection is a duplex stream (both readable and
+writable) that implements React's
+[`DuplexStreamInterface`](https://github.com/reactphp/stream#duplexstreaminterface).
+It contains additional properties for the local and remote address (client IP)
+where this connection has been established to/from.
+
+Most commonly, instances implementing this `ConnectionInterface` are emitted
+by all classes implementing the [`ServerInterface`](#serverinterface) and
+used by all classes implementing the [`ConnectorInterface`](#connectorinterface).
+
+Because the `ConnectionInterface` implements the underlying
+[`DuplexStreamInterface`](https://github.com/reactphp/stream#duplexstreaminterface)
+you can use any of its events and methods as usual:
+
+```php
+$connection->on('data', function ($chunk) {
+    echo $chunk;
+});
+
+$connection->on('end', function () {
+    echo 'ended';
+});
+
+$connection->on('error', function (Exception $e) {
+    echo 'error: ' . $e->getMessage();
+});
+
+$connection->on('close', function () {
+    echo 'closed';
+});
+
+$connection->write($data);
+$connection->end($data = null);
+$connection->close();
+// …
+```
+
+For more details, see the
+[`DuplexStreamInterface`](https://github.com/reactphp/stream#duplexstreaminterface).
+
+#### getRemoteAddress()
+
+The `getRemoteAddress(): ?string` method returns the full remote address
+(URI) where this connection has been established with.
+
+```php
+$address = $connection->getRemoteAddress();
+echo 'Connection with ' . $address . PHP_EOL;
+```
+
+If the remote address can not be determined or is unknown at this time (such as
+after the connection has been closed), it MAY return a `NULL` value instead.
+
+Otherwise, it will return the full address (URI) as a string value, such
+as `tcp://127.0.0.1:8080`, `tcp://[::1]:80`, `tls://127.0.0.1:443`,
+`unix://example.sock` or `unix:///path/to/example.sock`.
+Note that individual URI components are application specific and depend
+on the underlying transport protocol.
+
+If this is a TCP/IP based connection and you only want the remote IP, you may
+use something like this:
+
+```php
+$address = $connection->getRemoteAddress();
+$ip = trim(parse_url($address, PHP_URL_HOST), '[]');
+echo 'Connection with ' . $ip . PHP_EOL;
+```
+
+#### getLocalAddress()
+
+The `getLocalAddress(): ?string` method returns the full local address
+(URI) where this connection has been established with.
+
+```php
+$address = $connection->getLocalAddress();
+echo 'Connection with ' . $address . PHP_EOL;
+```
+
+If the local address can not be determined or is unknown at this time (such as
+after the connection has been closed), it MAY return a `NULL` value instead.
+
+Otherwise, it will return the full address (URI) as a string value, such
+as `tcp://127.0.0.1:8080`, `tcp://[::1]:80`, `tls://127.0.0.1:443`,
+`unix://example.sock` or `unix:///path/to/example.sock`.
+Note that individual URI components are application specific and depend
+on the underlying transport protocol.
+
+This method complements the [`getRemoteAddress()`](#getremoteaddress) method,
+so they should not be confused.
+
+If your `TcpServer` instance is listening on multiple interfaces (e.g. using
+the address `0.0.0.0`), you can use this method to find out which interface
+actually accepted this connection (such as a public or local interface).
+
+If your system has multiple interfaces (e.g. a WAN and a LAN interface),
+you can use this method to find out which interface was actually
+used for this connection.
+
+## Server usage
+
+### ServerInterface
+
+The `ServerInterface` is responsible for providing an interface for accepting
+incoming streaming connections, such as a normal TCP/IP connection.
+
+Most higher-level components (such as a HTTP server) accept an instance
+implementing this interface to accept incoming streaming connections.
+This is usually done via dependency injection, so it's fairly simple to actually
+swap this implementation against any other implementation of this interface.
+This means that you SHOULD typehint against this interface instead of a concrete
+implementation of this interface.
+
+Besides defining a few methods, this interface also implements the
+[`EventEmitterInterface`](https://github.com/igorw/evenement)
+which allows you to react to certain events.
+
+#### connection event
+
+The `connection` event will be emitted whenever a new connection has been
+established, i.e. a new client connects to this server socket:
+
+```php
+$server->on('connection', function (ConnectionInterface $connection) {
+    echo 'new connection' . PHP_EOL;
+});
+```
+
+See also the [`ConnectionInterface`](#connectioninterface) for more details
+about handling the incoming connection.
+
+#### error event
+
+The `error` event will be emitted whenever there's an error accepting a new
+connection from a client.
+
+```php
+$server->on('error', function (Exception $e) {
+    echo 'error: ' . $e->getMessage() . PHP_EOL;
+});
+```
+
+Note that this is not a fatal error event, i.e. the server keeps listening for
+new connections even after this event.
+
+
+#### getAddress()
+
+The `getAddress(): ?string` method can be used to
+return the full address (URI) this server is currently listening on.
+
+```php
+$address = $server->getAddress();
+echo 'Server listening on ' . $address . PHP_EOL;
+```
+
+If the address can not be determined or is unknown at this time (such as
+after the socket has been closed), it MAY return a `NULL` value instead.
+
+Otherwise, it will return the full address (URI) as a string value, such
+as `tcp://127.0.0.1:8080`, `tcp://[::1]:80`, `tls://127.0.0.1:443`
+`unix://example.sock` or `unix:///path/to/example.sock`.
+Note that individual URI components are application specific and depend
+on the underlying transport protocol.
+
+If this is a TCP/IP based server and you only want the local port, you may
+use something like this:
+
+```php
+$address = $server->getAddress();
+$port = parse_url($address, PHP_URL_PORT);
+echo 'Server listening on port ' . $port . PHP_EOL;
+```
+
+#### pause()
+
+The `pause(): void` method can be used to
+pause accepting new incoming connections.
+
+Removes the socket resource from the EventLoop and thus stop accepting
+new connections. Note that the listening socket stays active and is not
+closed.
+
+This means that new incoming connections will stay pending in the
+operating system backlog until its configurable backlog is filled.
+Once the backlog is filled, the operating system may reject further
+incoming connections until the backlog is drained again by resuming
+to accept new connections.
+
+Once the server is paused, no futher `connection` events SHOULD
+be emitted.
+
+```php
+$server->pause();
+
+$server->on('connection', assertShouldNeverCalled());
+```
+
+This method is advisory-only, though generally not recommended, the
+server MAY continue emitting `connection` events.
+
+Unless otherwise noted, a successfully opened server SHOULD NOT start
+in paused state.
+
+You can continue processing events by calling `resume()` again.
+
+Note that both methods can be called any number of times, in particular
+calling `pause()` more than once SHOULD NOT have any effect.
+Similarly, calling this after `close()` is a NO-OP.
+
+#### resume()
+
+The `resume(): void` method can be used to
+resume accepting new incoming connections.
+
+Re-attach the socket resource to the EventLoop after a previous `pause()`.
+
+```php
+$server->pause();
+
+$loop->addTimer(1.0, function () use ($server) {
+    $server->resume();
+});
+```
+
+Note that both methods can be called any number of times, in particular
+calling `resume()` without a prior `pause()` SHOULD NOT have any effect.
+Similarly, calling this after `close()` is a NO-OP.
+
+#### close()
+
+The `close(): void` method can be used to
+shut down this listening socket.
+
+This will stop listening for new incoming connections on this socket.
+
+```php
+echo 'Shutting down server socket' . PHP_EOL;
+$server->close();
+```
+
+Calling this method more than once on the same instance is a NO-OP.
+
+### Server
+
+The `Server` class is the main class in this package that implements the
+[`ServerInterface`](#serverinterface) and allows you to accept incoming
+streaming connections, such as plaintext TCP/IP or secure TLS connection streams.
+Connections can also be accepted on Unix domain sockets.
+
+```php
+$server = new Server(8080, $loop);
+```
+
+As above, the `$uri` parameter can consist of only a port, in which case the
+server will default to listening on the localhost address `127.0.0.1`,
+which means it will not be reachable from outside of this system.
+
+In order to use a random port assignment, you can use the port `0`:
+
+```php
+$server = new Server(0, $loop);
+$address = $server->getAddress();
+```
+
+In order to change the host the socket is listening on, you can provide an IP
+address through the first parameter provided to the constructor, optionally
+preceded by the `tcp://` scheme:
+
+```php
+$server = new Server('192.168.0.1:8080', $loop);
+```
+
+If you want to listen on an IPv6 address, you MUST enclose the host in square
+brackets:
+
+```php
+$server = new Server('[::1]:8080', $loop);
+```
+
+To listen on a Unix domain socket (UDS) path, you MUST prefix the URI with the
+`unix://` scheme:
+
+```php
+$server = new Server('unix:///tmp/server.sock', $loop);
+```
+
+If the given URI is invalid, does not contain a port, any other scheme or if it
+contains a hostname, it will throw an `InvalidArgumentException`:
+
+```php
+// throws InvalidArgumentException due to missing port
+$server = new Server('127.0.0.1', $loop);
+```
+
+If the given URI appears to be valid, but listening on it fails (such as if port
+is already in use or port below 1024 may require root access etc.), it will
+throw a `RuntimeException`:
+
+```php
+$first = new Server(8080, $loop);
+
+// throws RuntimeException because port is already in use
+$second = new Server(8080, $loop);
+```
+
+> Note that these error conditions may vary depending on your system and/or
+  configuration.
+  See the exception message and code for more details about the actual error
+  condition.
+
+Optionally, you can specify [TCP socket context options](http://php.net/manual/en/context.socket.php)
+for the underlying stream socket resource like this:
+
+```php
+$server = new Server('[::1]:8080', $loop, array(
+    'tcp' => array(
+        'backlog' => 200,
+        'so_reuseport' => true,
+        'ipv6_v6only' => true
+    )
+));
+```
+
+> Note that available [socket context options](http://php.net/manual/en/context.socket.php),
+  their defaults and effects of changing these may vary depending on your system
+  and/or PHP version.
+  Passing unknown context options has no effect.
+  For BC reasons, you can also pass the TCP socket context options as a simple
+  array without wrapping this in another array under the `tcp` key.
+
+You can start a secure TLS (formerly known as SSL) server by simply prepending
+the `tls://` URI scheme.
+Internally, it will wait for plaintext TCP/IP connections and then performs a
+TLS handshake for each connection.
+It thus requires valid [TLS context options](http://php.net/manual/en/context.ssl.php),
+which in its most basic form may look something like this if you're using a
+PEM encoded certificate file:
+
+```php
+$server = new Server('tls://127.0.0.1:8080', $loop, array(
+    'tls' => array(
+        'local_cert' => 'server.pem'
+    )
+));
+```
+
+> Note that the certificate file will not be loaded on instantiation but when an
+  incoming connection initializes its TLS context.
+  This implies that any invalid certificate file paths or contents will only cause
+  an `error` event at a later time.
+
+If your private key is encrypted with a passphrase, you have to specify it
+like this:
+
+```php
+$server = new Server('tls://127.0.0.1:8000', $loop, array(
+    'tls' => array(
+        'local_cert' => 'server.pem',
+        'passphrase' => 'secret'
+    )
+));
+```
+
+By default, this server supports TLSv1.0+ and excludes support for legacy
+SSLv2/SSLv3. As of PHP 5.6+ you can also explicitly choose the TLS version you
+want to negotiate with the remote side:
+
+```php
+$server = new Server('tls://127.0.0.1:8000', $loop, array(
+    'tls' => array(
+        'local_cert' => 'server.pem',
+        'crypto_method' => STREAM_CRYPTO_METHOD_TLSv1_2_SERVER
+    )
+));
+```
+
+> Note that available [TLS context options](http://php.net/manual/en/context.ssl.php),
+  their defaults and effects of changing these may vary depending on your system
+  and/or PHP version.
+  The outer context array allows you to also use `tcp` (and possibly more)
+  context options at the same time.
+  Passing unknown context options has no effect.
+  If you do not use the `tls://` scheme, then passing `tls` context options
+  has no effect.
+
+Whenever a client connects, it will emit a `connection` event with a connection
+instance implementing [`ConnectionInterface`](#connectioninterface):
+
+```php
+$server->on('connection', function (ConnectionInterface $connection) {
+    echo 'Plaintext connection from ' . $connection->getRemoteAddress() . PHP_EOL;
+    
+    $connection->write('hello there!' . PHP_EOL);
+    …
+});
+```
+
+See also the [`ServerInterface`](#serverinterface) for more details.
+
+> Note that the `Server` class is a concrete implementation for TCP/IP sockets.
+  If you want to typehint in your higher-level protocol implementation, you SHOULD
+  use the generic [`ServerInterface`](#serverinterface) instead.
+
+### Advanced server usage
+
+#### TcpServer
+
+The `TcpServer` class implements the [`ServerInterface`](#serverinterface) and
+is responsible for accepting plaintext TCP/IP connections.
+
+```php
+$server = new TcpServer(8080, $loop);
+```
+

+$server->on('connection', function (ConnectionInterface $connection) {
+    echo 'Plaintext connection from ' . $connection->getRemoteAddress() . PHP_EOL;
+    
+    $connection->write('hello there!' . PHP_EOL);
+    …
+});
+```
+
+See also the [`ServerInterface`](#serverinterface) for more details.
+
+#### SecureServer
+
+The `SecureServer` class implements the [`ServerInterface`](#serverinterface)
+and is responsible for providing a secure TLS (formerly known as SSL) server.
+
+It does so by wrapping a [`TcpServer`](#tcpserver) instance which waits for plaintext
+TCP/IP connections and then performs a TLS handshake for each connection.
+It thus requires valid [TLS context options](http://php.net/manual/en/context.ssl.php),
+which in its most basic form may look something like this if you're using a
+PEM encoded certificate file:
+
+```php
+$server = new TcpServer(8000, $loop);
+$server = new SecureServer($server, $loop, array(
+    'local_cert' => 'server.pem'
+));
+```
+
+> Note that the certificate file will not be loaded on instantiation but when an
+incoming connection initializes its TLS context.
+This implies that any invalid certificate file paths or contents will only cause
+an `error` event at a later time.
+
+If your private key is encrypted with a passphrase, you have to specify it
+like this:
+
+```php
+$server = new TcpServer(8000, $loop);
+$server = new SecureServer($server, $loop, array(
+    'local_cert' => 'server.pem',
+    'passphrase' => 'secret'
+));
+```
+
+By default, this server supports TLSv1.0+ and excludes support for legacy
+SSLv2/SSLv3. As of PHP 5.6+ you can also explicitly choose the TLS version you
+want to negotiate with the remote side:
+
+```php

+    'crypto_method' => STREAM_CRYPTO_METHOD_TLSv1_2_SERVER
+));
+```
+
+> Note that available [TLS context options](http://php.net/manual/en/context.ssl.php),
+their defaults and effects of changing these may vary depending on your system
+and/or PHP version.
+Passing unknown context options has no effect.
+
+Whenever a client completes the TLS handshake, it will emit a `connection` event
+with a connection instance implementing [`ConnectionInterface`](#connectioninterface):
+
+```php
+$server->on('connection', function (ConnectionInterface $connection) {
+    echo 'Secure connection from' . $connection->getRemoteAddress() . PHP_EOL;
+    
+    $connection->write('hello there!' . PHP_EOL);
+    …
+});
+```
+
+Whenever a client fails to perform a successful TLS handshake, it will emit an
+`error` event and then close the underlying TCP/IP connection:
+
+```php
+$server->on('error', function (Exception $e) {
+    echo 'Error' . $e->getMessage() . PHP_EOL;
+});
+```
+
+See also the [`ServerInterface`](#serverinterface) for more details.
+
+Note that the `SecureServer` class is a concrete implementation for TLS sockets.
+If you want to typehint in your higher-level protocol implementation, you SHOULD
+use the generic [`ServerInterface`](#serverinterface) instead.
+
+> Advanced usage: Despite allowing any `ServerInterface` as first parameter,
+you SHOULD pass a `TcpServer` instance as first parameter, unless you
+know what you're doing.
+Internally, the `SecureServer` has to set the required TLS context options on
+the underlying stream resources.
+These resources are not exposed through any of the interfaces defined in this
+package, but only through the internal `Connection` class.
+The `TcpServer` class is guaranteed to emit connections that implement
+the `ConnectionInterface` and uses the internal `Connection` class in order to
+expose these underlying resources.
+If you use a custom `ServerInterface` and its `connection` event does not
+meet this requirement, the `SecureServer` will emit an `error` event and
+then close the underlying connection.
+
+#### UnixServer
+
+The `UnixServer` class implements the [`ServerInterface`](#serverinterface) and
+is responsible for accepting connections on Unix domain sockets (UDS).
+
+```php
+$server = new UnixServer('/tmp/server.sock', $loop);
+```
+
+As above, the `$uri` parameter can consist of only a socket path or socket path
+prefixed by the `unix://` scheme.
+
+If the given URI appears to be valid, but listening on it fails (such as if the
+socket is already in use or the file not accessible etc.), it will throw a
+`RuntimeException`:
+
+```php
+$first = new UnixServer('/tmp/same.sock', $loop);
+
+// throws RuntimeException because socket is already in use
+$second = new UnixServer('/tmp/same.sock', $loop);
+```
+
+Whenever a client connects, it will emit a `connection` event with a connection
+instance implementing [`ConnectionInterface`](#connectioninterface):
+
+```php
+$server->on('connection', function (ConnectionInterface $connection) {
+    echo 'New connection' . PHP_EOL;
+
+    $connection->write('hello there!' . PHP_EOL);
+    …
+});
+```
+
+See also the [`ServerInterface`](#serverinterface) for more details.
+
+#### LimitingServer
+
+The `LimitingServer` decorator wraps a given `ServerInterface` and is responsible
+for limiting and keeping track of open connections to this server instance.
+
+Whenever the underlying server emits a `connection` event, it will check its
+limits and then either
+ - keep track of this connection by adding it to the list of
+   open connections and then forward the `connection` event
+ - or reject (close) the connection when its limits are exceeded and will
+   forward an `error` event instead.
+
+Whenever a connection closes, it will remove this connection from the list of
+open connections.
+
+```php
+$server = new LimitingServer($server, 100);
+$server->on('connection', function (ConnectionInterface $connection) {
+    $connection->write('hello there!' . PHP_EOL);
+    …
+});
+```
+
+See also the [second example](examples) for more details.
+
+You have to pass a maximum number of open connections to ensure
+the server will automatically reject (close) connections once this limit
+is exceeded. In this case, it will emit an `error` event to inform about
+this and no `connection` event will be emitted.
+
+```php
+$server = new LimitingServer($server, 100);
+$server->on('connection', function (ConnectionInterface $connection) {
+    $connection->write('hello there!' . PHP_EOL);
+    …
+});
+```
+
+You MAY pass a `null` limit in order to put no limit on the number of
+open connections and keep accepting new connection until you run out of
+operating system resources (such as open file handles). This may be
+useful if you do not want to take care of applying a limit but still want
+to use the `getConnections()` method.
+
+You can optionally configure the server to pause accepting new
+connections once the connection limit is reached. In this case, it will
+pause the underlying server and no longer process any new connections at
+all, thus also no longer closing any excessive connections.
+The underlying operating system is responsible for keeping a backlog of
+pending connections until its limit is reached, at which point it will
+start rejecting further connections.
+Once the server is below the connection limit, it will continue consuming
+connections from the backlog and will process any outstanding data on
+each connection.
+This mode may be useful for some protocols that are designed to wait for
+a response message (such as HTTP), but may be less useful for other
+protocols that demand immediate responses (such as a "welcome" message in
+an interactive chat).
+
+```php
+$server = new LimitingServer($server, 100, true);
+$server->on('connection', function (ConnectionInterface $connection) {
+    $connection->write('hello there!' . PHP_EOL);
+    …
+});
+```
+
+##### getConnections()
+
+The `getConnections(): ConnectionInterface[]` method can be used to
+return an array with all currently active connections.
+
+```php
+foreach ($server->getConnection() as $connection) {
+    $connection->write('Hi!');
+}
+```
+
+## Client usage
+
+### ConnectorInterface
+
+The `ConnectorInterface` is responsible for providing an interface for
+establishing streaming connections, such as a normal TCP/IP connection.
+
+This is the main interface defined in this package and it is used throughout
+React's vast ecosystem.
+
+Most higher-level components (such as HTTP, database or other networking
+service clients) accept an instance implementing this interface to create their
+TCP/IP connection to the underlying networking service.
+This is usually done via dependency injection, so it's fairly simple to actually
+swap this implementation against any other implementation of this interface.
+
+The interface only offers a single method:
+
+#### connect()
+
+The `connect(string $uri): PromiseInterface<ConnectionInterface, Exception>` method
+can be used to create a streaming connection to the given remote address.
+
+It returns a [Promise](https://github.com/reactphp/promise) which either
+fulfills with a stream implementing [`ConnectionInterface`](#connectioninterface)
+on success or rejects with an `Exception` if the connection is not successful:
+
+```php
+$connector->connect('google.com:443')->then(
+    function (ConnectionInterface $connection) {
+        // connection successfully established
+    },
+    function (Exception $error) {
+        // failed to connect due to $error
+    }
+);
+```
+
+See also [`ConnectionInterface`](#connectioninterface) for more details.
+
+The returned Promise MUST be implemented in such a way that it can be
+cancelled when it is still pending. Cancelling a pending promise MUST
+reject its value with an `Exception`. It SHOULD clean up any underlying
+resources and references as applicable:
+
+```php
+$promise = $connector->connect($uri);
+
+$promise->cancel();
+```
+
+### Connector
+
+The `Connector` class is the main class in this package that implements the
+[`ConnectorInterface`](#connectorinterface) and allows you to create streaming connections.
+
+You can use this connector to create any kind of streaming connections, such
+as plaintext TCP/IP, secure TLS or local Unix connection streams.
+
+It binds to the main event loop and can be used like this:
+
+```php
+$loop = React\EventLoop\Factory::create();
+$connector = new Connector($loop);
+
+$connector->connect($uri)->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+
+$loop->run();
+```
+
+In order to create a plaintext TCP/IP connection, you can simply pass a host
+and port combination like this:
+
+```php
+$connector->connect('www.google.com:80')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+> If you do no specify a URI scheme in the destination URI, it will assume
+  `tcp://` as a default and establish a plaintext TCP/IP connection.
+  Note that TCP/IP connections require a host and port part in the destination
+  URI like above, all other URI components are optional.
+
+In order to create a secure TLS connection, you can use the `tls://` URI scheme
+like this:
+
+```php
+$connector->connect('tls://www.google.com:443')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+In order to create a local Unix domain socket connection, you can use the
+`unix://` URI scheme like this:
+
+```php
+$connector->connect('unix:///tmp/demo.sock')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+> The [`getRemoteAddress()`](#getremoteaddress) method will return the target
+  Unix domain socket (UDS) path as given to the `connect()` method, including
+  the `unix://` scheme, for example `unix:///tmp/demo.sock`.
+  The [`getLocalAddress()`](#getlocaladdress) method will most likely return a
+  `null` value as this value is not applicable to UDS connections here.
+
+Under the hood, the `Connector` is implemented as a *higher-level facade*
+for the lower-level connectors implemented in this package. This means it
+also shares all of their features and implementation details.
+If you want to typehint in your higher-level protocol implementation, you SHOULD
+use the generic [`ConnectorInterface`](#connectorinterface) instead.
+
+The `Connector` class will try to detect your system DNS settings (and uses
+Google's public DNS server `8.8.8.8` as a fallback if unable to determine your
+system settings) to resolve all public hostnames into underlying IP addresses by
+default.
+If you explicitly want to use a custom DNS server (such as a local DNS relay or
+a company wide DNS server), you can set up the `Connector` like this:
+
+```php
+$connector = new Connector($loop, array(
+    'dns' => '127.0.1.1'
+));
+
+$connector->connect('localhost:80')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+If you do not want to use a DNS resolver at all and want to connect to IP
+addresses only, you can also set up your `Connector` like this:
+
+```php
+$connector = new Connector($loop, array(
+    'dns' => false
+));
+
+$connector->connect('127.0.0.1:80')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+Advanced: If you need a custom DNS `Resolver` instance, you can also set up
+your `Connector` like this:
+
+```php
+$dnsResolverFactory = new React\Dns\Resolver\Factory();
+$resolver = $dnsResolverFactory->createCached('127.0.1.1', $loop);
+
+$connector = new Connector($loop, array(
+    'dns' => $resolver
+));
+
+$connector->connect('localhost:80')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+By default, the `tcp://` and `tls://` URI schemes will use timeout value that
+repects your `default_socket_timeout` ini setting (which defaults to 60s).
+If you want a custom timeout value, you can simply pass this like this:
+
+```php
+$connector = new Connector($loop, array(
+    'timeout' => 10.0
+));
+```
+
+Similarly, if you do not want to apply a timeout at all and let the operating
+system handle this, you can pass a boolean flag like this:
+
+```php
+$connector = new Connector($loop, array(
+    'timeout' => false
+));
+```
+
+By default, the `Connector` supports the `tcp://`, `tls://` and `unix://`
+URI schemes. If you want to explicitly prohibit any of these, you can simply
+pass boolean flags like this:
+
+```php
+// only allow secure TLS connections
+$connector = new Connector($loop, array(
+    'tcp' => false,
+    'tls' => true,
+    'unix' => false,
+));
+
+$connector->connect('tls://google.com:443')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+The `tcp://` and `tls://` also accept additional context options passed to
+the underlying connectors.
+If you want to explicitly pass additional context options, you can simply
+pass arrays of context options like this:
+
+```php
+// allow insecure TLS connections
+$connector = new Connector($loop, array(
+    'tcp' => array(
+        'bindto' => '192.168.0.1:0'
+    ),
+    'tls' => array(
+        'verify_peer' => false,
+        'verify_peer_name' => false
+    ),
+));
+
+$connector->connect('tls://localhost:443')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+By default, this connector supports TLSv1.0+ and excludes support for legacy
+SSLv2/SSLv3. As of PHP 5.6+ you can also explicitly choose the TLS version you
+want to negotiate with the remote side:
+
+```php
+$connector = new Connector($loop, array(
+    'tls' => array(
+        'crypto_method' => STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT
+    )
+));
+```
+
+> For more details about context options, please refer to the PHP documentation
+  about [socket context options](http://php.net/manual/en/context.socket.php)
+  and [SSL context options](http://php.net/manual/en/context.ssl.php).
+
+Advanced: By default, the `Connector` supports the `tcp://`, `tls://` and
+`unix://` URI schemes.
+For this, it sets up the required connector classes automatically.
+If you want to explicitly pass custom connectors for any of these, you can simply
+pass an instance implementing the `ConnectorInterface` like this:
+
+```php
+$dnsResolverFactory = new React\Dns\Resolver\Factory();
+$resolver = $dnsResolverFactory->createCached('127.0.1.1', $loop);
+$tcp = new DnsConnector(new TcpConnector($loop), $resolver);
+
+$tls = new SecureConnector($tcp, $loop);
+
+$unix = new UnixConnector($loop);
+
+$connector = new Connector($loop, array(
+    'tcp' => $tcp,
+    'tls' => $tls,
+    'unix' => $unix,
+
+    'dns' => false,
+    'timeout' => false,
+));
+
+$connector->connect('google.com:80')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+```
+
+> Internally, the `tcp://` connector will always be wrapped by the DNS resolver,
+  unless you disable DNS like in the above example. In this case, the `tcp://`
+  connector receives the actual hostname instead of only the resolved IP address
+  and is thus responsible for performing the lookup.
+  Internally, the automatically created `tls://` connector will always wrap the
+  underlying `tcp://` connector for establishing the underlying plaintext
+  TCP/IP connection before enabling secure TLS mode. If you want to use a custom
+  underlying `tcp://` connector for secure TLS connections only, you may
+  explicitly pass a `tls://` connector like above instead.
+  Internally, the `tcp://` and `tls://` connectors will always be wrapped by
+  `TimeoutConnector`, unless you disable timeouts like in the above example.
+
+### Advanced client usage
+
+#### TcpConnector
+
+The `React\Socket\TcpConnector` class implements the
+[`ConnectorInterface`](#connectorinterface) and allows you to create plaintext
+TCP/IP connections to any IP-port-combination:
+
+```php
+$tcpConnector = new React\Socket\TcpConnector($loop);
+
+$tcpConnector->connect('127.0.0.1:80')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+
+$loop->run();
+```
+
+See also the [examples](examples).
+
+Pending connection attempts can be cancelled by cancelling its pending promise like so:
+
+```php
+$promise = $tcpConnector->connect('127.0.0.1:80');
+
+$promise->cancel();
+```
+
+Calling `cancel()` on a pending promise will close the underlying socket
+resource, thus cancelling the pending TCP/IP connection, and reject the
+resulting promise.
+
+You can optionally pass additional
+[socket context options](http://php.net/manual/en/context.socket.php)
+to the constructor like this:
+
+```php
+$tcpConnector = new React\Socket\TcpConnector($loop, array(
+    'bindto' => '192.168.0.1:0'
+));
+```
+
+Note that this class only allows you to connect to IP-port-combinations.
+If the given URI is invalid, does not contain a valid IP address and port
+or contains any other scheme, it will reject with an
+`InvalidArgumentException`:
+
+If the given URI appears to be valid, but connecting to it fails (such as if
+the remote host rejects the connection etc.), it will reject with a
+`RuntimeException`.
+
+If you want to connect to hostname-port-combinations, see also the following chapter.
+
+> Advanced usage: Internally, the `TcpConnector` allocates an empty *context*
+resource for each stream resource.
+If the destination URI contains a `hostname` query parameter, its value will
+be used to set up the TLS peer name.
+This is used by the `SecureConnector` and `DnsConnector` to verify the peer
+name and can also be used if you want a custom TLS peer name.
+
+#### DnsConnector
+
+The `DnsConnector` class implements the
+[`ConnectorInterface`](#connectorinterface) and allows you to create plaintext
+TCP/IP connections to any hostname-port-combination.
+
+It does so by decorating a given `TcpConnector` instance so that it first
+looks up the given domain name via DNS (if applicable) and then establishes the
+underlying TCP/IP connection to the resolved target IP address.
+
+Make sure to set up your DNS resolver and underlying TCP connector like this:
+
+```php
+$dnsResolverFactory = new React\Dns\Resolver\Factory();
+$dns = $dnsResolverFactory->createCached('8.8.8.8', $loop);
+
+$dnsConnector = new React\Socket\DnsConnector($tcpConnector, $dns);
+
+$dnsConnector->connect('www.google.com:80')->then(function (ConnectionInterface $connection) {
+    $connection->write('...');
+    $connection->end();
+});
+
+$loop->run();
+```
+
+See also the [examples](examples).
+
+Pending connection attempts can be cancelled by cancelling its pending promise like so:
+
+```php
+$promise = $dnsConnector->connect('www.google.com:80');
+
+$promise->cancel();
+```
+
+Calling `cancel()` on a pending promise will cancel the underlying DNS lookup
+and/or the underlying TCP/IP connection and reject the resulting promise.
+
+> Advanced usage: Internally, the `DnsConnector` relies on a `Resolver` to
+look up the IP address for the given hostname.
+It will then replace the hostname in the destination URI with this IP and
+append a `hostname` query parameter and pass this updated URI to the underlying
+connector.
+The underlying connector is thus responsible for creating a connection to the
+target IP address, while this query parameter can be used to check the original
+hostname and is used by the `TcpConnector` to set up the TLS peer name.
+If a `hostname` is given explicitly, this query parameter will not be modified,
+which can be useful if you want a custom TLS peer name.
+
+#### SecureConnector
+
+The `SecureConnector` class implements the
+[`ConnectorInterface`](#connectorinterface) and allows you to create secure
+TLS (formerly known as SSL) connections to any hostname-port-combination.
+
+It does so by decorating a given `DnsConnector` instance so that it first
+creates a plaintext TCP/IP connection and then enables TLS encryption on this
+stream.
+
+```php
+$secureConnector = new React\Socket\SecureConnector($dnsConnector, $loop);
+
+$secureConnector->connect('www.google.com:443')->then(function (ConnectionInterface $connection) {
+    $connection->write("GET / HTTP/1.0\r\nHost: www.google.com\r\n\r\n");
+    ...
+});
+
+$loop->run();
+```
+
+See also the [examples](examples).
+
+Pending connection attempts can be cancelled by cancelling its pending promise like so:
+
+```php
+$promise = $secureConnector->connect('www.google.com:443');
+
+$promise->cancel();
+```
+
+Calling `cancel()` on a pending promise will cancel the underlying TCP/IP
+connection and/or the SSL/TLS negotiation and reject the resulting promise.
+
+You can optionally pass additional
+[SSL context options](http://php.net/manual/en/context.ssl.php)
+to the constructor like this:
+
+```php
+$secureConnector = new React\Socket\SecureConnector($dnsConnector, $loop, array(
+    'verify_peer' => false,
+    'verify_peer_name' => false
+));
+```
+
+By default, this connector supports TLSv1.0+ and excludes support for legacy
+SSLv2/SSLv3. As of PHP 5.6+ you can also explicitly choose the TLS version you
+want to negotiate with the remote side:
+
+```php
+$secureConnector = new React\Socket\SecureConnector($dnsConnector, $loop, array(
+    'crypto_method' => STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT
+));
+```
+
+> Advanced usage: Internally, the `SecureConnector` relies on setting up the
+required *context options* on the underlying stream resource.
+It should therefor be used with a `TcpConnector` somewhere in the connector
+stack so that it can allocate an empty *context* resource for each stream
+resource and verify the peer name.
+Failing to do so may result in a TLS peer name mismatch error or some hard to
+trace race conditions, because all stream resources will use a single, shared
+*default context* resource otherwise.
+
+#### TimeoutConnector
+
+The `TimeoutConnector` class implements the
+[`ConnectorInterface`](#connectorinterface) and allows you to add timeout
+handling to any existing connector instance.
+
+It does so by decorating any given [`ConnectorInterface`](#connectorinterface)
+instance and starting a timer that will automatically reject and abort any
+underlying connection attempt if it takes too long.
+
+```php
+$timeoutConnector = new React\Socket\TimeoutConnector($connector, 3.0, $loop);
+
+$timeoutConnector->connect('google.com:80')->then(function (ConnectionInterface $connection) {
+    // connection succeeded within 3.0 seconds
+});
+```
+
+See also any of the [examples](examples).
+
+Pending connection attempts can be cancelled by cancelling its pending promise like so:
+
+```php
+$promise = $timeoutConnector->connect('google.com:80');
+
+$promise->cancel();
+```
+
+Calling `cancel()` on a pending promise will cancel the underlying connection
+attempt, abort the timer and reject the resulting promise.
+
+#### UnixConnector
+
+The `UnixConnector` class implements the
+[`ConnectorInterface`](#connectorinterface) and allows you to connect to
+Unix domain socket (UDS) paths like this:
+
+```php
+$connector = new React\Socket\UnixConnector($loop);
+
+$connector->connect('/tmp/demo.sock')->then(function (ConnectionInterface $connection) {
+    $connection->write("HELLO\n");
+});
+
+$loop->run();
+```
+
+Connecting to Unix domain sockets is an atomic operation, i.e. its promise will
+settle (either resolve or reject) immediately.
+As such, calling `cancel()` on the resulting promise has no effect.
+
+> The [`getRemoteAddress()`](#getremoteaddress) method will return the target
+  Unix domain socket (UDS) path as given to the `connect()` method, prepended
+  with the `unix://` scheme, for example `unix:///tmp/demo.sock`.
+  The [`getLocalAddress()`](#getlocaladdress) method will most likely return a
+  `null` value as this value is not applicable to UDS connections here.
+
+#### FixedUriConnector
+
+The `FixedUriConnector` class implements the
+[`ConnectorInterface`](#connectorinterface) and decorates an existing Connector
+to always use a fixed, preconfigured URI.
+
+This can be useful for consumers that do not support certain URIs, such as
+when you want to explicitly connect to a Unix domain socket (UDS) path
+instead of connecting to a default address assumed by an higher-level API:
+
+```php
+$connector = new FixedUriConnector(
+    'unix:///var/run/docker.sock',
+    new UnixConnector($loop)
+);
+
+// destination will be ignored, actually connects to Unix domain socket
+$promise = $connector->connect('localhost:80');
+```
+
+## Install
+
+The recommended way to install this library is [through Composer](https://getcomposer.org).
+[New to Composer?](https://getcomposer.org/doc/00-intro.md)
+
+This will install the latest supported version:
+
+```bash
+$ composer require react/socket:^0.8.12
+```
+
+See also the [CHANGELOG](CHANGELOG.md) for details about version upgrades.
+
+This project aims to run on any platform and thus does not require any PHP
+extensions and supports running on legacy PHP 5.3 through current PHP 7+ and HHVM.
+It's *highly recommended to use PHP 7+* for this project, partly due to its vast
+performance improvements and partly because legacy PHP versions require several
+workarounds as described below.
+
+Secure TLS connections received some major upgrades starting with PHP 5.6, with
+the defaults now being more secure, while older versions required explicit
+context options.
+This library does not take responsibility over these context options, so it's
+up to consumers of this library to take care of setting appropriate context
+options as described above.
+
+All versions of PHP prior to 5.6.8 suffered from a buffering issue where reading
+from a streaming TLS connection could be one `data` event behind.
+This library implements a work-around to try to flush the complete incoming
+data buffers on these legacy PHP versions, which has a penalty of around 10% of
+throughput on all connections.
+With this work-around, we have not been able to reproduce this issue anymore,
+but we have seen reports of people saying this could still affect some of the
+older PHP versions (`5.5.23`, `5.6.7`, and `5.6.8`).
+Note that this only affects *some* higher-level streaming protocols, such as
+IRC over TLS, but should not affect HTTP over TLS (HTTPS).
+Further investigation of this issue is needed.
+For more insights, this issue is also covered by our test suite.
+
+PHP < 7.1.4 (and PHP < 7.0.18) suffers from a bug when writing big
+chunks of data over TLS streams at once.
+We try to work around this by limiting the write chunk size to 8192
+bytes for older PHP versions only.
+This is only a work-around and has a noticable performance penalty on
+affected versions.
+
+This project also supports running on HHVM.
+Note that really old HHVM < 3.8 does not support secure TLS connections, as it
+lacks the required `stream_socket_enable_crypto()` function.
+As such, trying to create a secure TLS connections on affected versions will
+return a rejected promise instead.
+This issue is also covered by our test suite, which will skip related tests
+on affected versions.
+
+## Tests
+
+To run the test suite, you first need to clone this repo and then install all
+dependencies [through Composer](https://getcomposer.org):
+
+```bash
+$ composer install
+```
+
+To run the test suite, go to the project root and run:
+
+```bash
+$ php vendor/bin/phpunit
+```
+
+The test suite also contains a number of functional integration tests that rely
+on a stable internet connection.
+If you do not want to run these, they can simply be skipped like this:
+
+```bash
+$ php vendor/bin/phpunit --exclude-group internet
+```

+     * incoming connection initializes its TLS context.
+     * This implies that any invalid certificate file paths or contents will only cause
+     * an `error` event at a later time.
+     *
+     * If your private key is encrypted with a passphrase, you have to specify it
+     * like this:
+     *
+     * ```php
+     * $server = new TcpServer(8000, $loop);

+     * ```

+     * Note that available [TLS context options],
+     * their defaults and effects of changing these may vary depending on your system
+     * and/or PHP version.

+     * you SHOULD pass a `TcpServer` instance as first parameter, unless you

+     * the underlying stream resources.
+     * These resources are not exposed through any of the interfaces defined in this
+     * package, but only through the internal `Connection` class.
+     * The `TcpServer` class is guaranteed to emit connections that implement
+     * the `ConnectionInterface` and uses the internal `Connection` class in order to
+     * expose these underlying resources.
+     * If you use a custom `ServerInterface` and its `connection` event does not

+ *
+ * Besides defining a few methods, this interface also implements the
+ * `EventEmitterInterface` which allows you to react to certain events:
+ *
+ * connection event:
+ *     The `connection` event will be emitted whenever a new connection has been
+ *     established, i.e. a new client connects to this server socket:
+ *
+ *     ```php
+ *     $server->on('connection', function (ConnectionInterface $connection) {

+ *     });
+ *     ```
+ *
+ *     See also the `ConnectionInterface` for more details about handling the
+ *     incoming connection.
+ *
+ * error event:
+ *     The `error` event will be emitted whenever there's an error accepting a new
+ *     connection from a client.
+ *
+ *     ```php
+ *     $server->on('error', function (Exception $e) {
+ *         echo 'error: ' . $e->getMessage() . PHP_EOL;
+ *     });
+ *     ```

+     * which means it will not be reachable from outside of this system.
+     *
+     * In order to use a random port assignment, you can use the port `0`:

+     * $address = $server->getAddress();

+     * ```php

+     * brackets:
+     *
+     * ```php
+     * $server = new TcpServer('[::1]:8080', $loop);
+     * ```
+     *
+     * If the given URI is invalid, does not contain a port, any other scheme or if it
+     * contains a hostname, it will throw an `InvalidArgumentException`:
+     *
+     * ```php
+     * // throws InvalidArgumentException due to missing port
+     * $server = new TcpServer('127.0.0.1', $loop);
+     * ```
+     *
+     * If the given URI appears to be valid, but listening on it fails (such as if port
+     * is already in use or port below 1024 may require root access etc.), it will
+     * throw a `RuntimeException`:
+     *
+     * ```php
+     * $first = new TcpServer(8080, $loop);
+     *
+     * // throws RuntimeException because port is already in use
+     * $second = new TcpServer(8080, $loop);

+     * configuration.
+     * See the exception message and code for more details about the actual error
+     * condition.
+     *
+     * Optionally, you can specify [socket context options](http://php.net/manual/en/context.socket.php)
+     * for the underlying stream socket resource like this:

+     * ```php

+     *
+     * Note that available [socket context options](http://php.net/manual/en/context.socket.php),

+    (#113 by @docteurklein and #114 and #115 by @clue)
+
+*   Improve test suite by running against Mac OS X on Travis
+    (#112 by @clue)

+
+*   Feature: Add optional `$writeChunkSize` parameter to limit maximum number of
+    bytes to write at once.
+    (#105 by @clue)
+
+    ```php
+    $stream = new WritableResourceStream(STDOUT, $loop, null, 8192);
+    ```
+
+*   Ignore HHVM test failures for now until Travis tests work again
+    (#106 by @clue)
+
+## 0.7.0 (2017-05-04)
+
+*   Removed / BC break: Remove deprecated and unneeded functionality
+    (#45, #87, #90, #91 and #93 by @clue)
+
+    *   Remove deprecated `Stream` class, use `DuplexResourceStream` instead
+        (#87 by @clue)
+      
+    *   Remove public `$buffer` property, use new constructor parameters instead
+        (#91 by @clue)
+
+    *   Remove public `$stream` property from all resource streams
+        (#90 by @clue)
+
+    *   Remove undocumented and now unused `ReadableStream` and `WritableStream`
+        (#93 by @clue)
+
+    *   Remove `BufferedSink`
+        (#45 by @clue)
+
+*   Feature / BC break: Simplify `ThroughStream` by using data callback instead of
+    inheritance. It is now a direct implementation of `DuplexStreamInterface`.
+    (#88 and #89 by @clue)
+
+    ```php
+    $through = new ThroughStream(function ($data) {
+        return json_encode($data) . PHP_EOL;
+    });
+    $through->on('data', $this->expectCallableOnceWith("[2, true]\n"));
+
+    $through->write(array(2, true));
+    ```
+
+*   Feature / BC break: The `CompositeStream` starts closed if either side is
+    already closed and forwards pause to pipe source on first write attempt.
+    (#96 and #103 by @clue)
+    
+    If either side of the composite stream closes, it will also close the other
+    side. We now also ensure that if either side is already closed during
+    instantiation, it will also close the other side.
+
+*   BC break: Mark all classes as `final` and
+    mark internal API as `private` to discourage inheritance
+    (#95 and #99 by @clue)
+
+*   Feature / BC break: Only emit `error` event for fatal errors
+    (#92 by @clue)
+
+    >   The `error` event was previously also allowed to be emitted for non-fatal
+        errors, but our implementations actually only ever emitted this as a fatal
+        error and then closed the stream.
+
+*   Feature: Explicitly allow custom events and exclude any semantics
+    (#97 by @clue)
+
+*   Strict definition for event callback functions
+    (#101 by @clue)
+
+*   Support legacy PHP 5.3 through PHP 7.1 and HHVM and improve usage documentation
+    (#100 and #102 by @clue)
+
+*   Actually require all dependencies so this is self-contained and improve
+    forward compatibility with EventLoop v1.0 and v0.5
+    (#94 and #98 by @clue)
+
+## 0.6.0 (2017-03-26)
+
+* Feature / Fix / BC break: Add `DuplexResourceStream` and deprecate `Stream`
+  (#85 by @clue)
+
+  ```php
+  // old (does still work for BC reasons)
+  $stream = new Stream($connection, $loop);
+
+  // new
+  $stream = new DuplexResourceStream($connection, $loop);
+  ```
+
+  Note that the `DuplexResourceStream` now rejects read-only or write-only
+  streams, so this may affect BC. If you want a read-only or write-only
+  resource, use `ReadableResourceStream` or `WritableResourceStream` instead of
+  `DuplexResourceStream`.
+
+  > BC note: This class was previously called `Stream`. The `Stream` class still
+    exists for BC reasons and will be removed in future versions of this package.
+
+* Feature / BC break: Add `WritableResourceStream` (previously called `Buffer`)
+  (#84 by @clue)
+
+  ```php
+  // old
+  $stream = new Buffer(STDOUT, $loop);
+
+  // new
+  $stream = new WritableResourceStream(STDOUT, $loop);
+  ```
+
+* Feature: Add `ReadableResourceStream`
+  (#83 by @clue)
+
+  ```php
+  $stream = new ReadableResourceStream(STDIN, $loop);
+  ```
+
+* Fix / BC Break: Enforce using non-blocking I/O
+  (#46 by @clue)
+
+  > BC note: This is known to affect process pipes on Windows which do not
+    support non-blocking I/O and could thus block the whole EventLoop previously.
+
+* Feature / Fix / BC break: Consistent semantics for
+  `DuplexStreamInterface::end()` to ensure it SHOULD also end readable side
+  (#86 by @clue)
+
+* Fix: Do not use unbuffered reads on pipe streams for legacy PHP < 5.4
+  (#80 by @clue)
+
+## 0.5.0 (2017-03-08)
+
+* Feature / BC break: Consistent `end` event semantics (EOF)
+  (#70 by @clue)
+  
+  The `end` event will now only be emitted for a *successful* end, not if the
+  stream closes due to an unrecoverable `error` event or if you call `close()`
+  explicitly.
+  If you want to detect when the stream closes (terminates), use the `close`
+  event instead.
+
+* BC break: Remove custom (undocumented) `full-drain` event from `Buffer`
+  (#63 and #68 by @clue)
+
+  > The `full-drain` event was undocumented and mostly used internally.
+    Relying on this event has attracted some low-quality code in the past, so
+    we've removed this from the public API in order to work out a better
+    solution instead.
+    If you want to detect when the buffer finishes flushing data to the stream,
+    you may want to look into its `end()` method or the `close` event instead.
+
+* Feature / BC break: Consistent event semantics and documentation,
+  explicitly state *when* events will be emitted and *which* arguments they
+  receive.
+  (#73 and #69 by @clue)
+
+  The documentation now explicitly defines each event and its arguments.
+  Custom events and event arguments are still supported.
+  Most notably, all defined events only receive inherently required event
+  arguments and no longer transmit the instance they are emitted on for
+  consistency and performance reasons.
+
+  ```php
+  // old (inconsistent and not supported by all implementations)
+  $stream->on('data', function ($data, $stream) {
+      // process $data
+  });
+
+  // new (consistent throughout the whole ecosystem)
+  $stream->on('data', function ($data) use ($stream) {
+      // process $data
+  });
+  ```
+
+  > This mostly adds documentation (and thus some stricter, consistent 
+    definitions) for the existing behavior, it does NOT define any major
+    changes otherwise.
+    Most existing code should be compatible with these changes, unless
+    it relied on some undocumented/unintended semantics.
+
+* Feature / BC break: Consistent method semantics and documentation
+  (#72 by @clue)
+
+  > This mostly adds documentation (and thus some stricter, consistent
+    definitions) for the existing behavior, it does NOT define any major
+    changes otherwise.
+    Most existing code should be compatible with these changes, unless
+    it relied on some undocumented/unintended semantics.
+
+* Feature: Consistent `pipe()` semantics for closed and closing streams
+  (#71 from @clue)
+
+  The source stream will now always be paused via `pause()` when the
+  destination stream closes. Also, properly stop piping if the source
+  stream closes and remove all event forwarding.
+
+* Improve test suite by adding PHPUnit to `require-dev` and improving coverage.
+  (#74 and #75 by @clue, #66 by @nawarian)
+
+## 0.4.6 (2017-01-25)
+
+* Feature: The `Buffer` can now be injected into the `Stream` (or be used standalone)
+  (#62 by @clue)
+
+* Fix: Forward `close` event only once for `CompositeStream` and `ThroughStream`
+  (#60 by @clue)
+
+* Fix: Consistent `close` event behavior for `Buffer`
+  (#61 by @clue)
+
+## 0.4.5 (2016-11-13)
+
+* Feature: Support setting read buffer size to `null` (infinite)
+  (#42 by @clue)
+
+* Fix: Do not emit `full-drain` event if `Buffer` is closed during `drain` event
+  (#55 by @clue)
+
+* Vastly improved performance by factor of 10x to 20x.
+  Raise default buffer sizes to 64 KiB and simplify and improve error handling
+  and unneeded function calls.
+  (#53, #55, #56 by @clue)
+
+## 0.4.4 (2016-08-22)
+
+* Bug fix: Emit `error` event and close `Stream` when accessing the underlying
+  stream resource fails with a permanent error.
+  (#52 and #40 by @clue, #25 by @lysenkobv)
+
+* Bug fix: Do not emit empty `data` event if nothing has been read (stream reached EOF)
+  (#39 by @clue)
+
+* Bug fix: Ignore empty writes to `Buffer`
+  (#51 by @clue)
+
+* Add benchmarking script to measure throughput in CI
+  (#41 by @clue)

+# Stream
+
+[![Build Status](https://travis-ci.org/reactphp/stream.svg?branch=master)](https://travis-ci.org/reactphp/stream)
+
+Event-driven readable and writable streams for non-blocking I/O in [ReactPHP](https://reactphp.org/).
+
+In order to make the [EventLoop](https://github.com/reactphp/event-loop)
+easier to use, this component introduces the powerful concept of "streams".
+Streams allow you to efficiently process huge amounts of data (such as a multi
+Gigabyte file download) in small chunks without having to store everything in
+memory at once.
+They are very similar to the streams found in PHP itself,
+but have an interface more suited for async, non-blocking I/O.

+## Stream usage
+
+ReactPHP uses the concept of "streams" throughout its ecosystem to provide a
+consistent higher-level abstraction for processing streams of arbitrary data
+contents and size.
+While a stream itself is a quite low-level concept, it can be used as a powerful
+abstraction to build higher-level components and protocols on top.
+
+If you're new to this concept, it helps to think of them as a water pipe:
+You can consume water from a source or you can produce water and forward (pipe)
+it to any destination (sink).
+
+Similarly, streams can either be
+
+* readable (such as `STDIN` terminal input) or
+* writable (such as `STDOUT` terminal output) or
+* duplex (both readable *and* writable, such as a TCP/IP connection)
+
+Accordingly, this package defines the following three interfaces
+
+* [`ReadableStreamInterface`](#readablestreaminterface)
+* [`WritableStreamInterface`](#writablestreaminterface)
+* [`DuplexStreamInterface`](#duplexstreaminterface)
+
+### ReadableStreamInterface
+
+The `ReadableStreamInterface` is responsible for providing an interface for
+read-only streams and the readable side of duplex streams.
+
+Besides defining a few methods, this interface also implements the
+`EventEmitterInterface` which allows you to react to certain events.
+
+The event callback functions MUST be a valid `callable` that obeys strict
+parameter definitions and MUST accept event parameters exactly as documented.
+The event callback functions MUST NOT throw an `Exception`.
+The return value of the event callback functions will be ignored and has no
+effect, so for performance reasons you're recommended to not return any
+excessive data structures.
+
+Every implementation of this interface MUST follow these event semantics in
+order to be considered a well-behaving stream.
+
+> Note that higher-level implementations of this interface may choose to
+  define additional events with dedicated semantics not defined as part of
+  this low-level stream specification. Conformance with these event semantics
+  is out of scope for this interface, so you may also have to refer to the
+  documentation of such a higher-level implementation.
+
+#### data event
+
+The `data` event will be emitted whenever some data was read/received
+from this source stream.
+The event receives a single mixed argument for incoming data.
+
+```php
+$stream->on('data', function ($data) {
+    echo $data;
+});
+```
+
+This event MAY be emitted any number of times, which may be zero times if
+this stream does not send any data at all.
+It SHOULD not be emitted after an `end` or `close` event.
+
+The given `$data` argument may be of mixed type, but it's usually
+recommended it SHOULD be a `string` value or MAY use a type that allows
+representation as a `string` for maximum compatibility.
+
+Many common streams (such as a TCP/IP connection or a file-based stream)
+will emit the raw (binary) payload data that is received over the wire as
+chunks of `string` values.
+
+Due to the stream-based nature of this, the sender may send any number
+of chunks with varying sizes. There are no guarantees that these chunks
+will be received with the exact same framing the sender intended to send.
+In other words, many lower-level protocols (such as TCP/IP) transfer the
+data in chunks that may be anywhere between single-byte values to several
+dozens of kilobytes. You may want to apply a higher-level protocol to
+these low-level data chunks in order to achieve proper message framing.
+  
+#### end event
+
+The `end` event will be emitted once the source stream has successfully
+reached the end of the stream (EOF).
+
+```php
+$stream->on('end', function () {
+    echo 'END';
+});
+```
+
+This event SHOULD be emitted once or never at all, depending on whether
+a successful end was detected.
+It SHOULD NOT be emitted after a previous `end` or `close` event.
+It MUST NOT be emitted if the stream closes due to a non-successful
+end, such as after a previous `error` event.
+
+After the stream is ended, it MUST switch to non-readable mode,
+see also `isReadable()`.
+
+This event will only be emitted if the *end* was reached successfully,
+not if the stream was interrupted by an unrecoverable error or explicitly
+closed. Not all streams know this concept of a "successful end".
+Many use-cases involve detecting when the stream closes (terminates)
+instead, in this case you should use the `close` event.
+After the stream emits an `end` event, it SHOULD usually be followed by a
+`close` event.
+
+Many common streams (such as a TCP/IP connection or a file-based stream)
+will emit this event if either the remote side closes the connection or
+a file handle was successfully read until reaching its end (EOF).
+
+Note that this event should not be confused with the `end()` method.
+This event defines a successful end *reading* from a source stream, while
+the `end()` method defines *writing* a successful end to a destination
+stream.
+
+#### error event
+
+The `error` event will be emitted once a fatal error occurs, usually while
+trying to read from this stream.
+The event receives a single `Exception` argument for the error instance.
+
+```php
+$server->on('error', function (Exception $e) {
+    echo 'Error: ' . $e->getMessage() . PHP_EOL;
+});
+```
+
+This event SHOULD be emitted once the stream detects a fatal error, such
+as a fatal transmission error or after an unexpected `data` or premature
+`end` event.
+It SHOULD NOT be emitted after a previous `error`, `end` or `close` event.
+It MUST NOT be emitted if this is not a fatal error condition, such as
+a temporary network issue that did not cause any data to be lost.
+
+After the stream errors, it MUST close the stream and SHOULD thus be
+followed by a `close` event and then switch to non-readable mode, see
+also `close()` and `isReadable()`.
+
+Many common streams (such as a TCP/IP connection or a file-based stream)
+only deal with data transmission and do not make assumption about data
+boundaries (such as unexpected `data` or premature `end` events).
+In other words, many lower-level protocols (such as TCP/IP) may choose
+to only emit this for a fatal transmission error once and will then
+close (terminate) the stream in response.
+
+If this stream is a `DuplexStreamInterface`, you should also notice
+how the writable side of the stream also implements an `error` event.
+In other words, an error may occur while either reading or writing the
+stream which should result in the same error processing.
+
+#### close event
+
+The `close` event will be emitted once the stream closes (terminates).
+
+```php
+$stream->on('close', function () {
+    echo 'CLOSED';
+});
+```
+
+This event SHOULD be emitted once or never at all, depending on whether
+the stream ever terminates.
+It SHOULD NOT be emitted after a previous `close` event.
+
+After the stream is closed, it MUST switch to non-readable mode,
+see also `isReadable()`.
+
+Unlike the `end` event, this event SHOULD be emitted whenever the stream
+closes, irrespective of whether this happens implicitly due to an
+unrecoverable error or explicitly when either side closes the stream.
+If you only want to detect a *successful* end, you should use the `end`
+event instead.
+
+Many common streams (such as a TCP/IP connection or a file-based stream)
+will likely choose to emit this event after reading a *successful* `end`
+event or after a fatal transmission `error` event.
+
+If this stream is a `DuplexStreamInterface`, you should also notice
+how the writable side of the stream also implements a `close` event.
+In other words, after receiving this event, the stream MUST switch into
+non-writable AND non-readable mode, see also `isWritable()`.
+Note that this event should not be confused with the `end` event.
+
+#### isReadable()
+
+The `isReadable(): bool` method can be used to
+check whether this stream is in a readable state (not closed already).
+
+This method can be used to check if the stream still accepts incoming
+data events or if it is ended or closed already.
+Once the stream is non-readable, no further `data` or `end` events SHOULD
+be emitted.
+
+```php
+assert($stream->isReadable() === false);
+
+$stream->on('data', assertNeverCalled());
+$stream->on('end', assertNeverCalled());
+```
+
+A successfully opened stream always MUST start in readable mode.
+
+Once the stream ends or closes, it MUST switch to non-readable mode.
+This can happen any time, explicitly through `close()` or
+implicitly due to a remote close or an unrecoverable transmission error.
+Once a stream has switched to non-readable mode, it MUST NOT transition
+back to readable mode.
+
+If this stream is a `DuplexStreamInterface`, you should also notice
+how the writable side of the stream also implements an `isWritable()`
+method. Unless this is a half-open duplex stream, they SHOULD usually
+have the same return value.
+
+#### pause()
+
+The `pause(): void` method can be used to
+pause reading incoming data events.
+
+Removes the data source file descriptor from the event loop. This
+allows you to throttle incoming data.
+
+Unless otherwise noted, a successfully opened stream SHOULD NOT start
+in paused state.
+
+Once the stream is paused, no futher `data` or `end` events SHOULD
+be emitted.
+
+```php
+$stream->pause();
+
+$stream->on('data', assertShouldNeverCalled());
+$stream->on('end', assertShouldNeverCalled());
+```
+
+This method is advisory-only, though generally not recommended, the
+stream MAY continue emitting `data` events.
+
+You can continue processing events by calling `resume()` again.
+
+Note that both methods can be called any number of times, in particular
+calling `pause()` more than once SHOULD NOT have any effect.
+
+See also `resume()`.
+
+#### resume()
+
+The `resume(): void` method can be used to
+resume reading incoming data events.
+
+Re-attach the data source after a previous `pause()`.
+
+```php
+$stream->pause();
+
+$loop->addTimer(1.0, function () use ($stream) {
+    $stream->resume();
+});
+```
+
+Note that both methods can be called any number of times, in particular
+calling `resume()` without a prior `pause()` SHOULD NOT have any effect.
+ 
+See also `pause()`.
+
+#### pipe()
+
+The `pipe(WritableStreamInterface $dest, array $options = [])` method can be used to
+pipe all the data from this readable source into the given writable destination.
+
+Automatically sends all incoming data to the destination.
+Automatically throttles the source based on what the destination can handle.
+
+```php
+$source->pipe($dest);
+```
+
+Similarly, you can also pipe an instance implementing `DuplexStreamInterface`
+into itself in order to write back all the data that is received.
+This may be a useful feature for a TCP/IP echo service:
+
+```php
+$connection->pipe($connection);
+```
+
+This method returns the destination stream as-is, which can be used to
+set up chains of piped streams:
+
+```php
+$source->pipe($decodeGzip)->pipe($filterBadWords)->pipe($dest);
+```
+
+By default, this will call `end()` on the destination stream once the
+source stream emits an `end` event. This can be disabled like this:
+
+```php
+$source->pipe($dest, array('end' => false));
+```
+
+Note that this only applies to the `end` event.
+If an `error` or explicit `close` event happens on the source stream,
+you'll have to manually close the destination stream:
+
+```php
+$source->pipe($dest);
+$source->on('close', function () use ($dest) {
+    $dest->end('BYE!');
+});
+```
+
+If the source stream is not readable (closed state), then this is a NO-OP.
+
+```php
+$source->close();
+$source->pipe($dest); // NO-OP
+```
+
+If the destinantion stream is not writable (closed state), then this will simply
+throttle (pause) the source stream:
+
+```php
+$dest->close();
+$source->pipe($dest); // calls $source->pause()
+```
+
+Similarly, if the destination stream is closed while the pipe is still
+active, it will also throttle (pause) the source stream:
+
+```php
+$source->pipe($dest);
+$dest->close(); // calls $source->pause()
+```
+
+Once the pipe is set up successfully, the destination stream MUST emit
+a `pipe` event with this source stream an event argument.
+
+#### close()
+
+The `close(): void` method can be used to
+close the stream (forcefully).
+
+This method can be used to (forcefully) close the stream.
+
+```php
+$stream->close();
+```
+
+Once the stream is closed, it SHOULD emit a `close` event.
+Note that this event SHOULD NOT be emitted more than once, in particular
+if this method is called multiple times.
+
+After calling this method, the stream MUST switch into a non-readable
+mode, see also `isReadable()`.
+This means that no further `data` or `end` events SHOULD be emitted.
+
+```php
+$stream->close();
+assert($stream->isReadable() === false);
+
+$stream->on('data', assertNeverCalled());
+$stream->on('end', assertNeverCalled());
+```
+
+If this stream is a `DuplexStreamInterface`, you should also notice
+how the writable side of the stream also implements a `close()` method.
+In other words, after calling this method, the stream MUST switch into
+non-writable AND non-readable mode, see also `isWritable()`.
+Note that this method should not be confused with the `end()` method.
+
+### WritableStreamInterface
+
+The `WritableStreamInterface` is responsible for providing an interface for
+write-only streams and the writable side of duplex streams.
+
+Besides defining a few methods, this interface also implements the
+`EventEmitterInterface` which allows you to react to certain events.
+
+The event callback functions MUST be a valid `callable` that obeys strict
+parameter definitions and MUST accept event parameters exactly as documented.
+The event callback functions MUST NOT throw an `Exception`.
+The return value of the event callback functions will be ignored and has no
+effect, so for performance reasons you're recommended to not return any
+excessive data structures.
+
+Every implementation of this interface MUST follow these event semantics in
+order to be considered a well-behaving stream.
+
+> Note that higher-level implementations of this interface may choose to
+  define additional events with dedicated semantics not defined as part of
+  this low-level stream specification. Conformance with these event semantics
+  is out of scope for this interface, so you may also have to refer to the
+  documentation of such a higher-level implementation.
+
+#### drain event
+
+The `drain` event will be emitted whenever the write buffer became full
+previously and is now ready to accept more data.
+
+```php
+$stream->on('drain', function () use ($stream) {
+    echo 'Stream is now ready to accept more data';
+});
+```
+
+This event SHOULD be emitted once every time the buffer became full
+previously and is now ready to accept more data.
+In other words, this event MAY be emitted any number of times, which may
+be zero times if the buffer never became full in the first place.
+This event SHOULD NOT be emitted if the buffer has not become full
+previously.
+
+This event is mostly used internally, see also `write()` for more details.
+
+#### pipe event
+
+The `pipe` event will be emitted whenever a readable stream is `pipe()`d
+into this stream.
+The event receives a single `ReadableStreamInterface` argument for the
+source stream.
+
+```php
+$stream->on('pipe', function (ReadableStreamInterface $source) use ($stream) {
+    echo 'Now receiving piped data';
+
+    // explicitly close target if source emits an error
+    $source->on('error', function () use ($stream) {
+        $stream->close();
+    });
+});
+
+$source->pipe($stream);
+```
+
+This event MUST be emitted once for each readable stream that is
+successfully piped into this destination stream.
+In other words, this event MAY be emitted any number of times, which may
+be zero times if no stream is ever piped into this stream.
+This event MUST NOT be emitted if either the source is not readable
+(closed already) or this destination is not writable (closed already).
+
+This event is mostly used internally, see also `pipe()` for more details.
+
+#### error event
+
+The `error` event will be emitted once a fatal error occurs, usually while
+trying to write to this stream.
+The event receives a single `Exception` argument for the error instance.
+
+```php
+$stream->on('error', function (Exception $e) {
+    echo 'Error: ' . $e->getMessage() . PHP_EOL;
+});
+```
+
+This event SHOULD be emitted once the stream detects a fatal error, such
+as a fatal transmission error.
+It SHOULD NOT be emitted after a previous `error` or `close` event.
+It MUST NOT be emitted if this is not a fatal error condition, such as
+a temporary network issue that did not cause any data to be lost.
+
+After the stream errors, it MUST close the stream and SHOULD thus be
+followed by a `close` event and then switch to non-writable mode, see
+also `close()` and `isWritable()`.
+
+Many common streams (such as a TCP/IP connection or a file-based stream)
+only deal with data transmission and may choose
+to only emit this for a fatal transmission error once and will then
+close (terminate) the stream in response.
+
+If this stream is a `DuplexStreamInterface`, you should also notice
+how the readable side of the stream also implements an `error` event.
+In other words, an error may occur while either reading or writing the
+stream which should result in the same error processing.
+
+#### close event
+
+The `close` event will be emitted once the stream closes (terminates).
+
+```php
+$stream->on('close', function () {
+    echo 'CLOSED';
+});
+```
+
+This event SHOULD be emitted once or never at all, depending on whether
+the stream ever terminates.
+It SHOULD NOT be emitted after a previous `close` event.
+
+After the stream is closed, it MUST switch to non-writable mode,
+see also `isWritable()`.
+
+This event SHOULD be emitted whenever the stream closes, irrespective of
+whether this happens implicitly due to an unrecoverable error or
+explicitly when either side closes the stream.
+
+Many common streams (such as a TCP/IP connection or a file-based stream)
+will likely choose to emit this event after flushing the buffer from
+the `end()` method, after receiving a *successful* `end` event or after
+a fatal transmission `error` event.
+
+If this stream is a `DuplexStreamInterface`, you should also notice
+how the readable side of the stream also implements a `close` event.
+In other words, after receiving this event, the stream MUST switch into
+non-writable AND non-readable mode, see also `isReadable()`.
+Note that this event should not be confused with the `end` event.
+
+#### isWritable()
+
+The `isWritable(): bool` method can be used to
+check whether this stream is in a writable state (not closed already).
+
+This method can be used to check if the stream still accepts writing
+any data or if it is ended or closed already.
+Writing any data to a non-writable stream is a NO-OP:
+
+```php
+assert($stream->isWritable() === false);
+
+$stream->write('end'); // NO-OP
+$stream->end('end'); // NO-OP
+```
+
+A successfully opened stream always MUST start in writable mode.
+
+Once the stream ends or closes, it MUST switch to non-writable mode.
+This can happen any time, explicitly through `end()` or `close()` or
+implicitly due to a remote close or an unrecoverable transmission error.
+Once a stream has switched to non-writable mode, it MUST NOT transition
+back to writable mode.
+
+If this stream is a `DuplexStreamInterface`, you should also notice
+how the readable side of the stream also implements an `isReadable()`
+method. Unless this is a half-open duplex stream, they SHOULD usually
+have the same return value.
+
+#### write()
+
+The `write(mixed $data): bool` method can be used to
+write some data into the stream.
+
+A successful write MUST be confirmed with a boolean `true`, which means
+that either the data was written (flushed) immediately or is buffered and
+scheduled for a future write. Note that this interface gives you no
+control over explicitly flushing the buffered data, as finding the
+appropriate time for this is beyond the scope of this interface and left
+up to the implementation of this interface.
+
+Many common streams (such as a TCP/IP connection or file-based stream)
+may choose to buffer all given data and schedule a future flush by using
+an underlying EventLoop to check when the resource is actually writable.
+
+If a stream cannot handle writing (or flushing) the data, it SHOULD emit
+an `error` event and MAY `close()` the stream if it can not recover from
+this error.
+
+If the internal buffer is full after adding `$data`, then `write()`
+SHOULD return `false`, indicating that the caller should stop sending
+data until the buffer drains.
+The stream SHOULD send a `drain` event once the buffer is ready to accept
+more data.
+
+Similarly, if the the stream is not writable (already in a closed state)
+it MUST NOT process the given `$data` and SHOULD return `false`,
+indicating that the caller should stop sending data.
+
+The given `$data` argument MAY be of mixed type, but it's usually
+recommended it SHOULD be a `string` value or MAY use a type that allows
+representation as a `string` for maximum compatibility.
+
+Many common streams (such as a TCP/IP connection or a file-based stream)
+will only accept the raw (binary) payload data that is transferred over
+the wire as chunks of `string` values.
+
+Due to the stream-based nature of this, the sender may send any number
+of chunks with varying sizes. There are no guarantees that these chunks
+will be received with the exact same framing the sender intended to send.
+In other words, many lower-level protocols (such as TCP/IP) transfer the
+data in chunks that may be anywhere between single-byte values to several
+dozens of kilobytes. You may want to apply a higher-level protocol to
+these low-level data chunks in order to achieve proper message framing.
+
+#### end()
+
+The `end(mixed $data = null): void` method can be used to
+successfully end the stream (after optionally sending some final data).
+
+This method can be used to successfully end the stream, i.e. close
+the stream after sending out all data that is currently buffered.
+
+```php
+$stream->write('hello');
+$stream->write('world');
+$stream->end();
+```
+
+If there's no data currently buffered and nothing to be flushed, then
+this method MAY `close()` the stream immediately.
+
+If there's still data in the buffer that needs to be flushed first, then
+this method SHOULD try to write out this data and only then `close()`
+the stream.
+Once the stream is closed, it SHOULD emit a `close` event.
+
+Note that this interface gives you no control over explicitly flushing
+the buffered data, as finding the appropriate time for this is beyond the
+scope of this interface and left up to the implementation of this
+interface.
+
+Many common streams (such as a TCP/IP connection or file-based stream)
+may choose to buffer all given data and schedule a future flush by using
+an underlying EventLoop to check when the resource is actually writable.
+
+You can optionally pass some final data that is written to the stream
+before ending the stream. If a non-`null` value is given as `$data`, then
+this method will behave just like calling `write($data)` before ending
+with no data.
+
+```php
+// shorter version
+$stream->end('bye');
+
+// same as longer version
+$stream->write('bye');
+$stream->end();
+```
+
+After calling this method, the stream MUST switch into a non-writable
+mode, see also `isWritable()`.
+This means that no further writes are possible, so any additional
+`write()` or `end()` calls have no effect.
+
+```php
+$stream->end();
+assert($stream->isWritable() === false);
+
+$stream->write('nope'); // NO-OP
+$stream->end(); // NO-OP
+```
+
+If this stream is a `DuplexStreamInterface`, calling this method SHOULD
+also end its readable side, unless the stream supports half-open mode.
+In other words, after calling this method, these streams SHOULD switch
+into non-writable AND non-readable mode, see also `isReadable()`.
+This implies that in this case, the stream SHOULD NOT emit any `data`
+or `end` events anymore.
+Streams MAY choose to use the `pause()` method logic for this, but
+special care may have to be taken to ensure a following call to the
+`resume()` method SHOULD NOT continue emitting readable events.
+
+Note that this method should not be confused with the `close()` method.
+
+#### close()
+
+The `close(): void` method can be used to
+close the stream (forcefully).
+
+This method can be used to forcefully close the stream, i.e. close
+the stream without waiting for any buffered data to be flushed.
+If there's still data in the buffer, this data SHOULD be discarded.
+
+```php
+$stream->close();
+```
+
+Once the stream is closed, it SHOULD emit a `close` event.
+Note that this event SHOULD NOT be emitted more than once, in particular
+if this method is called multiple times.
+
+After calling this method, the stream MUST switch into a non-writable
+mode, see also `isWritable()`.
+This means that no further writes are possible, so any additional
+`write()` or `end()` calls have no effect.
+
+```php
+$stream->close();
+assert($stream->isWritable() === false);
+
+$stream->write('nope'); // NO-OP
+$stream->end(); // NO-OP
+```
+
+Note that this method should not be confused with the `end()` method.
+Unlike the `end()` method, this method does not take care of any existing
+buffers and simply discards any buffer contents.
+Likewise, this method may also be called after calling `end()` on a
+stream in order to stop waiting for the stream to flush its final data.
+
+```php
+$stream->end();
+$loop->addTimer(1.0, function () use ($stream) {
+    $stream->close();
+});
+```
+
+If this stream is a `DuplexStreamInterface`, you should also notice
+how the readable side of the stream also implements a `close()` method.
+In other words, after calling this method, the stream MUST switch into
+non-writable AND non-readable mode, see also `isReadable()`.
+
+### DuplexStreamInterface
+
+The `DuplexStreamInterface` is responsible for providing an interface for
+duplex streams (both readable and writable).
+
+It builds on top of the existing interfaces for readable and writable streams
+and follows the exact same method and event semantics.
+If you're new to this concept, you should look into the
+`ReadableStreamInterface` and `WritableStreamInterface` first.
+
+Besides defining a few methods, this interface also implements the
+`EventEmitterInterface` which allows you to react to the same events defined
+on the `ReadbleStreamInterface` and `WritableStreamInterface`.
+
+The event callback functions MUST be a valid `callable` that obeys strict
+parameter definitions and MUST accept event parameters exactly as documented.
+The event callback functions MUST NOT throw an `Exception`.
+The return value of the event callback functions will be ignored and has no
+effect, so for performance reasons you're recommended to not return any
+excessive data structures.
+
+Every implementation of this interface MUST follow these event semantics in
+order to be considered a well-behaving stream.
+
+> Note that higher-level implementations of this interface may choose to
+  define additional events with dedicated semantics not defined as part of
+  this low-level stream specification. Conformance with these event semantics
+  is out of scope for this interface, so you may also have to refer to the
+  documentation of such a higher-level implementation.
+
+See also [`ReadableStreamInterface`](#readablestreaminterface) and
+[`WritableStreamInterface`](#writablestreaminterface) for more details.
+
+## Creating streams
+
+ReactPHP uses the concept of "streams" throughout its ecosystem, so that
+many higher-level consumers of this package only deal with
+[stream usage](#stream-usage).
+This implies that stream instances are most often created within some
+higher-level components and many consumers never actually have to deal with
+creating a stream instance.
+
+* Use [react/socket](https://github.com/reactphp/socket)
+  if you want to accept incoming or establish outgoing plaintext TCP/IP or
+  secure TLS socket connection streams.
+* Use [react/http](https://github.com/reactphp/http)
+  if you want to receive an incoming HTTP request body streams.
+* Use [react/child-process](https://github.com/reactphp/child-process)
+  if you want to communicate with child processes via process pipes such as
+  STDIN, STDOUT, STDERR etc.
+* Use experimental [react/filesystem](https://github.com/reactphp/filesystem)
+  if you want to read from / write to the filesystem.
+* See also the last chapter for [more real-world applications](#more).
+
+However, if you are writing a lower-level component or want to create a stream
+instance from a stream resource, then the following chapter is for you.
+
+> Note that the following examples use `fopen()` and `stream_socket_client()`
+  for illustration purposes only.
+  These functions SHOULD NOT be used in a truly async program because each call
+  may take several seconds to complete and would block the EventLoop otherwise.
+  Additionally, the `fopen()` call will return a file handle on some platforms
+  which may or may not be supported by all EventLoop implementations.
+  As an alternative, you may want to use higher-level libraries listed above.
+
+### ReadableResourceStream
+
+The `ReadableResourceStream` is a concrete implementation of the
+[`ReadableStreamInterface`](#readablestreaminterface) for PHP's stream resources.
+
+This can be used to represent a read-only resource like a file stream opened in
+readable mode or a stream such as `STDIN`:
+
+```php
+$stream = new ReadableResourceStream(STDIN, $loop);
+$stream->on('data', function ($chunk) {
+    echo $chunk;
+});
+$stream->on('end', function () {
+    echo 'END';
+});
+```
+
+See also [`ReadableStreamInterface`](#readablestreaminterface) for more details.
+
+The first parameter given to the constructor MUST be a valid stream resource
+that is opened in reading mode (e.g. `fopen()` mode `r`).
+Otherwise, it will throw an `InvalidArgumentException`:
+
+```php
+// throws InvalidArgumentException
+$stream = new ReadableResourceStream(false, $loop);
+```
+
+See also the [`DuplexResourceStream`](#readableresourcestream) for read-and-write
+stream resources otherwise.
+
+Internally, this class tries to enable non-blocking mode on the stream resource
+which may not be supported for all stream resources.
+Most notably, this is not supported by pipes on Windows (STDIN etc.).
+If this fails, it will throw a `RuntimeException`:
+
+```php
+// throws RuntimeException on Windows
+$stream = new ReadableResourceStream(STDIN, $loop);
+```
+
+Once the constructor is called with a valid stream resource, this class will
+take care of the underlying stream resource.
+You SHOULD only use its public API and SHOULD NOT interfere with the underlying
+stream resource manually.
+
+This class takes an optional `int|null $readChunkSize` parameter that controls
+the maximum buffer size in bytes to read at once from the stream.
+You can use a `null` value here in order to apply its default value.
+This value SHOULD NOT be changed unless you know what you're doing.
+This can be a positive number which means that up to X bytes will be read
+at once from the underlying stream resource. Note that the actual number
+of bytes read may be lower if the stream resource has less than X bytes
+currently available.
+This can be `-1` which means "read everything available" from the
+underlying stream resource.
+This should read until the stream resource is not readable anymore
+(i.e. underlying buffer drained), note that this does not neccessarily
+mean it reached EOF.
+
+```php
+$stream = new ReadableResourceStream(STDIN, $loop, 8192);
+```
+
+> PHP bug warning: If the PHP process has explicitly been started without a
+  `STDIN` stream, then trying to read from `STDIN` may return data from
+  another stream resource. This does not happen if you start this with an empty
+  stream like `php test.php < /dev/null` instead of `php test.php <&-`.
+  See [#81](https://github.com/reactphp/stream/issues/81) for more details.
+
+### WritableResourceStream
+
+The `WritableResourceStream` is a concrete implementation of the
+[`WritableStreamInterface`](#writablestreaminterface) for PHP's stream resources.
+
+This can be used to represent a write-only resource like a file stream opened in
+writable mode or a stream such as `STDOUT` or `STDERR`:
+
+```php
+$stream = new WritableResourceStream(STDOUT, $loop);
+$stream->write('hello!');
+$stream->end();
+```
+
+See also [`WritableStreamInterface`](#writablestreaminterface) for more details.
+
+The first parameter given to the constructor MUST be a valid stream resource
+that is opened for writing.
+Otherwise, it will throw an `InvalidArgumentException`:
+
+```php
+// throws InvalidArgumentException
+$stream = new WritableResourceStream(false, $loop);
+```
+
+See also the [`DuplexResourceStream`](#readableresourcestream) for read-and-write
+stream resources otherwise.
+
+Internally, this class tries to enable non-blocking mode on the stream resource
+which may not be supported for all stream resources.
+Most notably, this is not supported by pipes on Windows (STDOUT, STDERR etc.).
+If this fails, it will throw a `RuntimeException`:
+
+```php
+// throws RuntimeException on Windows
+$stream = new WritableResourceStream(STDOUT, $loop);
+```
+
+Once the constructor is called with a valid stream resource, this class will
+take care of the underlying stream resource.
+You SHOULD only use its public API and SHOULD NOT interfere with the underlying
+stream resource manually.
+
+Any `write()` calls to this class will not be performed instantly, but will
+be performed asynchronously, once the EventLoop reports the stream resource is
+ready to accept data.
+For this, it uses an in-memory buffer string to collect all outstanding writes.
+This buffer has a soft-limit applied which defines how much data it is willing
+to accept before the caller SHOULD stop sending further data.
+
+This class takes an optional `int|null $writeBufferSoftLimit` parameter that controls
+this maximum buffer size in bytes.
+You can use a `null` value here in order to apply its default value.
+This value SHOULD NOT be changed unless you know what you're doing.
+
+```php
+$stream = new WritableResourceStream(STDOUT, $loop, 8192);
+```
+
+This class takes an optional `int|null $writeChunkSize` parameter that controls
+this maximum buffer size in bytes to write at once to the stream.
+You can use a `null` value here in order to apply its default value.
+This value SHOULD NOT be changed unless you know what you're doing.
+This can be a positive number which means that up to X bytes will be written
+at once to the underlying stream resource. Note that the actual number
+of bytes written may be lower if the stream resource has less than X bytes
+currently available.
+This can be `-1` which means "write everything available" to the
+underlying stream resource.
+
+```php
+$stream = new WritableResourceStream(STDOUT, $loop, null, 8192);
+```
+
+See also [`write()`](#write) for more details.
+
+### DuplexResourceStream
+
+The `DuplexResourceStream` is a concrete implementation of the
+[`DuplexStreamInterface`](#duplexstreaminterface) for PHP's stream resources.
+
+This can be used to represent a read-and-write resource like a file stream opened
+in read and write mode mode or a stream such as a TCP/IP connection:
+
+```php
+$conn = stream_socket_client('tcp://google.com:80');
+$stream = new DuplexResourceStream($conn, $loop);
+$stream->write('hello!');
+$stream->end();
+```
+
+See also [`DuplexStreamInterface`](#duplexstreaminterface) for more details.
+
+The first parameter given to the constructor MUST be a valid stream resource
+that is opened for reading *and* writing.
+Otherwise, it will throw an `InvalidArgumentException`:
+
+```php
+// throws InvalidArgumentException
+$stream = new DuplexResourceStream(false, $loop);
+```
+
+See also the [`ReadableResourceStream`](#readableresourcestream) for read-only
+and the [`WritableResourceStream`](#writableresourcestream) for write-only
+stream resources otherwise.
+
+Internally, this class tries to enable non-blocking mode on the stream resource
+which may not be supported for all stream resources.
+Most notably, this is not supported by pipes on Windows (STDOUT, STDERR etc.).
+If this fails, it will throw a `RuntimeException`:
+
+```php
+// throws RuntimeException on Windows
+$stream = new DuplexResourceStream(STDOUT, $loop);
+```
+
+Once the constructor is called with a valid stream resource, this class will
+take care of the underlying stream resource.
+You SHOULD only use its public API and SHOULD NOT interfere with the underlying
+stream resource manually.
+
+This class takes an optional `int|null $readChunkSize` parameter that controls
+the maximum buffer size in bytes to read at once from the stream.
+You can use a `null` value here in order to apply its default value.
+This value SHOULD NOT be changed unless you know what you're doing.
+This can be a positive number which means that up to X bytes will be read
+at once from the underlying stream resource. Note that the actual number
+of bytes read may be lower if the stream resource has less than X bytes
+currently available.
+This can be `-1` which means "read everything available" from the
+underlying stream resource.
+This should read until the stream resource is not readable anymore
+(i.e. underlying buffer drained), note that this does not neccessarily
+mean it reached EOF.
+
+```php
+$conn = stream_socket_client('tcp://google.com:80');
+$stream = new DuplexResourceStream($conn, $loop, 8192);
+```
+
+Any `write()` calls to this class will not be performed instantly, but will
+be performed asynchronously, once the EventLoop reports the stream resource is
+ready to accept data.
+For this, it uses an in-memory buffer string to collect all outstanding writes.
+This buffer has a soft-limit applied which defines how much data it is willing
+to accept before the caller SHOULD stop sending further data.
+
+This class takes another optional `WritableStreamInterface|null $buffer` parameter
+that controls this write behavior of this stream.
+You can use a `null` value here in order to apply its default value.
+This value SHOULD NOT be changed unless you know what you're doing.
+
+If you want to change the write buffer soft limit, you can pass an instance of
+[`WritableResourceStream`](#writableresourcestream) like this:
+
+```php
+$conn = stream_socket_client('tcp://google.com:80');
+$buffer = new WritableResourceStream($conn, $loop, 8192);
+$stream = new DuplexResourceStream($conn, $loop, null, $buffer);
+```
+
+See also [`WritableResourceStream`](#writableresourcestream) for more details.
+
+### ThroughStream
+
+The `ThroughStream` implements the
+[`DuplexStreamInterface`](#duplexstreaminterface) and will simply pass any data
+you write to it through to its readable end.
+
+```php
+$through = new ThroughStream();
+$through->on('data', $this->expectCallableOnceWith('hello'));
+
+$through->write('hello');
+```
+
+Similarly, the [`end()` method](#end) will end the stream and emit an
+[`end` event](#end-event) and then [`close()`](#close-1) the stream.
+The [`close()` method](#close-1) will close the stream and emit a
+[`close` event](#close-event).
+Accordingly, this is can also be used in a [`pipe()`](#pipe) context like this:
+
+```php
+$through = new ThroughStream();
+$source->pipe($through)->pipe($dest);
+```
+
+Optionally, its constructor accepts any callable function which will then be
+used to *filter* any data written to it. This function receives a single data
+argument as passed to the writable side and must return the data as it will be
+passed to its readable end:
+
+```php
+$through = new ThroughStream('strtoupper');
+$source->pipe($through)->pipe($dest);
+```
+
+Note that this class makes no assumptions about any data types. This can be
+used to convert data, for example for transforming any structured data into
+a newline-delimited JSON (NDJSON) stream like this:
+
+```php
+$through = new ThroughStream(function ($data) {
+    return json_encode($data) . PHP_EOL;
+});
+$through->on('data', $this->expectCallableOnceWith("[2, true]\n"));
+
+$through->write(array(2, true));
+```
+
+The callback function is allowed to throw an `Exception`. In this case,
+the stream will emit an `error` event and then [`close()`](#close-1) the stream.
+
+```php
+$through = new ThroughStream(function ($data) {
+    if (!is_string($data)) {
+        throw new \UnexpectedValueException('Only strings allowed');
+    }
+    return $data;
+});
+$through->on('error', $this->expectCallableOnce()));
+$through->on('close', $this->expectCallableOnce()));
+$through->on('data', $this->expectCallableNever()));
+
+$through->write(2);
+```
+
+### CompositeStream
+
+The `CompositeStream` implements the
+[`DuplexStreamInterface`](#duplexstreaminterface) and can be used to create a
+single duplex stream from two individual streams implementing
+[`ReadableStreamInterface`](#readablestreaminterface) and
+[`WritableStreamInterface`](#writablestreaminterface) respectively.
+
+This is useful for some APIs which may require a single
+[`DuplexStreamInterface`](#duplexstreaminterface) or simply because it's often
+more convenient to work with a single stream instance like this:
+
+```php
+$stdin = new ReadableResourceStream(STDIN, $loop);
+$stdout = new WritableResourceStream(STDOUT, $loop);
+
+$stdio = new CompositeStream($stdin, $stdout);
+
+$stdio->on('data', function ($chunk) use ($stdio) {
+    $stdio->write('You said: ' . $chunk);
+});
+```
+
+This is a well-behaving stream which forwards all stream events from the
+underlying streams and forwards all streams calls to the underlying streams.
+
+If you `write()` to the duplex stream, it will simply `write()` to the
+writable side and return its status.
+
+If you `end()` the duplex stream, it will `end()` the writable side and will
+`pause()` the readable side.
+
+If you `close()` the duplex stream, both input streams will be closed.
+If either of the two input streams emits a `close` event, the duplex stream
+will also close.
+If either of the two input streams is already closed while constructing the
+duplex stream, it will `close()` the other side and return a closed stream.
+
+## Usage
+
+The following example can be used to pipe the contents of a source file into
+a destination file without having to ever read the whole file into memory:
+
+```php
+$loop = new React\EventLoop\StreamSelectLoop;
+
+$source = new React\Stream\ReadableResourceStream(fopen('source.txt', 'r'), $loop);
+$dest = new React\Stream\WritableResourceStream(fopen('destination.txt', 'w'), $loop);
+
+$source->pipe($dest);
+
+$loop->run();
+```
+
+> Note that this example uses `fopen()` for illustration purposes only.
+  This should not be used in a truly async program because the filesystem is
+  inherently blocking and each call could potentially take several seconds.
+  See also [creating streams](#creating-streams) for more sophisticated
+  examples.
+

+ * The `DuplexStreamInterface` is responsible for providing an interface for

+ *
+ * It builds on top of the existing interfaces for readable and writable streams
+ * and follows the exact same method and event semantics.
+ * If you're new to this concept, you should look into the
+ * `ReadableStreamInterface` and `WritableStreamInterface` first.
+ *
+ * Besides defining a few methods, this interface also implements the
+ * `EventEmitterInterface` which allows you to react to the same events defined
+ * on the `ReadbleStreamInterface` and `WritableStreamInterface`.
+ *
+ * The event callback functions MUST be a valid `callable` that obeys strict
+ * parameter definitions and MUST accept event parameters exactly as documented.
+ * The event callback functions MUST NOT throw an `Exception`.
+ * The return value of the event callback functions will be ignored and has no
+ * effect, so for performance reasons you're recommended to not return any
+ * excessive data structures.
+ *
+ * Every implementation of this interface MUST follow these event semantics in
+ * order to be considered a well-behaving stream.
+ *
+ * > Note that higher-level implementations of this interface may choose to
+ *   define additional events with dedicated semantics not defined as part of
+ *   this low-level stream specification. Conformance with these event semantics
+ *   is out of scope for this interface, so you may also have to refer to the
+ *   documentation of such a higher-level implementation.

+/**
+ * The `ReadableStreamInterface` is responsible for providing an interface for
+ * read-only streams and the readable side of duplex streams.
+ *
+ * Besides defining a few methods, this interface also implements the
+ * `EventEmitterInterface` which allows you to react to certain events:
+ *
+ * data event:
+ *     The `data` event will be emitted whenever some data was read/received
+ *     from this source stream.
+ *     The event receives a single mixed argument for incoming data.
+ *
+ *     ```php
+ *     $stream->on('data', function ($data) {
+ *         echo $data;
+ *     });
+ *     ```
+ *
+ *     This event MAY be emitted any number of times, which may be zero times if
+ *     this stream does not send any data at all.
+ *     It SHOULD not be emitted after an `end` or `close` event.
+ *
+ *     The given `$data` argument may be of mixed type, but it's usually
+ *     recommended it SHOULD be a `string` value or MAY use a type that allows
+ *     representation as a `string` for maximum compatibility.
+ *
+ *     Many common streams (such as a TCP/IP connection or a file-based stream)
+ *     will emit the raw (binary) payload data that is received over the wire as
+ *     chunks of `string` values.
+ *
+ *     Due to the stream-based nature of this, the sender may send any number
+ *     of chunks with varying sizes. There are no guarantees that these chunks
+ *     will be received with the exact same framing the sender intended to send.
+ *     In other words, many lower-level protocols (such as TCP/IP) transfer the
+ *     data in chunks that may be anywhere between single-byte values to several
+ *     dozens of kilobytes. You may want to apply a higher-level protocol to
+ *     these low-level data chunks in order to achieve proper message framing.
+ *
+ * end event:
+ *     The `end` event will be emitted once the source stream has successfully
+ *     reached the end of the stream (EOF).
+ *
+ *     ```php
+ *     $stream->on('end', function () {
+ *         echo 'END';
+ *     });
+ *     ```
+ *
+ *     This event SHOULD be emitted once or never at all, depending on whether
+ *     a successful end was detected.
+ *     It SHOULD NOT be emitted after a previous `end` or `close` event.
+ *     It MUST NOT be emitted if the stream closes due to a non-successful
+ *     end, such as after a previous `error` event.
+ *
+ *     After the stream is ended, it MUST switch to non-readable mode,
+ *     see also `isReadable()`.
+ *
+ *     This event will only be emitted if the *end* was reached successfully,
+ *     not if the stream was interrupted by an unrecoverable error or explicitly
+ *     closed. Not all streams know this concept of a "successful end".
+ *     Many use-cases involve detecting when the stream closes (terminates)
+ *     instead, in this case you should use the `close` event.
+ *     After the stream emits an `end` event, it SHOULD usually be followed by a
+ *     `close` event.
+ *
+ *     Many common streams (such as a TCP/IP connection or a file-based stream)
+ *     will emit this event if either the remote side closes the connection or
+ *     a file handle was successfully read until reaching its end (EOF).
+ *
+ *     Note that this event should not be confused with the `end()` method.
+ *     This event defines a successful end *reading* from a source stream, while
+ *     the `end()` method defines *writing* a successful end to a destination
+ *     stream.
+ *
+ * error event:
+ *     The `error` event will be emitted once a fatal error occurs, usually while
+ *     trying to read from this stream.
+ *     The event receives a single `Exception` argument for the error instance.
+ *
+ *     ```php
+ *     $stream->on('error', function (Exception $e) {
+ *         echo 'Error: ' . $e->getMessage() . PHP_EOL;
+ *     });
+ *     ```
+ *
+ *     This event SHOULD be emitted once the stream detects a fatal error, such
+ *     as a fatal transmission error or after an unexpected `data` or premature
+ *     `end` event.
+ *     It SHOULD NOT be emitted after a previous `error`, `end` or `close` event.
+ *     It MUST NOT be emitted if this is not a fatal error condition, such as
+ *     a temporary network issue that did not cause any data to be lost.
+ *
+ *     After the stream errors, it MUST close the stream and SHOULD thus be
+ *     followed by a `close` event and then switch to non-readable mode, see
+ *     also `close()` and `isReadable()`.
+ *
+ *     Many common streams (such as a TCP/IP connection or a file-based stream)
+ *     only deal with data transmission and do not make assumption about data
+ *     boundaries (such as unexpected `data` or premature `end` events).
+ *     In other words, many lower-level protocols (such as TCP/IP) may choose
+ *     to only emit this for a fatal transmission error once and will then
+ *     close (terminate) the stream in response.
+ *
+ *     If this stream is a `DuplexStreamInterface`, you should also notice
+ *     how the writable side of the stream also implements an `error` event.
+ *     In other words, an error may occur while either reading or writing the
+ *     stream which should result in the same error processing.
+ *
+ * close event:
+ *     The `close` event will be emitted once the stream closes (terminates).
+ *
+ *     ```php
+ *     $stream->on('close', function () {
+ *         echo 'CLOSED';
+ *     });
+ *     ```
+ *
+ *     This event SHOULD be emitted once or never at all, depending on whether
+ *     the stream ever terminates.
+ *     It SHOULD NOT be emitted after a previous `close` event.
+ *
+ *     After the stream is closed, it MUST switch to non-readable mode,
+ *     see also `isReadable()`.
+ *
+ *     Unlike the `end` event, this event SHOULD be emitted whenever the stream
+ *     closes, irrespective of whether this happens implicitly due to an
+ *     unrecoverable error or explicitly when either side closes the stream.
+ *     If you only want to detect a *successful* end, you should use the `end`
+ *     event instead.
+ *
+ *     Many common streams (such as a TCP/IP connection or a file-based stream)
+ *     will likely choose to emit this event after reading a *successful* `end`
+ *     event or after a fatal transmission `error` event.
+ *
+ *     If this stream is a `DuplexStreamInterface`, you should also notice
+ *     how the writable side of the stream also implements a `close` event.
+ *     In other words, after receiving this event, the stream MUST switch into
+ *     non-writable AND non-readable mode, see also `isWritable()`.
+ *     Note that this event should not be confused with the `end` event.
+ *
+ * The event callback functions MUST be a valid `callable` that obeys strict
+ * parameter definitions and MUST accept event parameters exactly as documented.
+ * The event callback functions MUST NOT throw an `Exception`.
+ * The return value of the event callback functions will be ignored and has no
+ * effect, so for performance reasons you're recommended to not return any
+ * excessive data structures.
+ *
+ * Every implementation of this interface MUST follow these event semantics in
+ * order to be considered a well-behaving stream.
+ *
+ * > Note that higher-level implementations of this interface may choose to
+ *   define additional events with dedicated semantics not defined as part of
+ *   this low-level stream specification. Conformance with these event semantics
+ *   is out of scope for this interface, so you may also have to refer to the
+ *   documentation of such a higher-level implementation.

+ * $through->on('data', $this->expectCallableOnceWith('hello'));
+ *

+ * The [`close()` method](#close-1) will close the stream and emit a
+ * [`close` event](#close-event).
+ * Accordingly, this is can also be used in a [`pipe()`](#pipe) context like this:
+ *
+ * ```php
+ * $through = new ThroughStream();
+ * $source->pipe($through)->pipe($dest);
+ * ```
+ *
+ * Optionally, its constructor accepts any callable function which will then be

+ *
+ * ```php
+ * $through = new ThroughStream('strtoupper');
+ * $source->pipe($through)->pipe($dest);
+ * ```
+ *
+ * Note that this class makes no assumptions about any data types. This can be

+ * a newline-delimited JSON (NDJSON) stream like this:
+ *
+ * ```php

+ *
+ * The callback function is allowed to throw an `Exception`. In this case,

+ *
+ * ```php

+/**
+ * The `WritableStreamInterface` is responsible for providing an interface for
+ * write-only streams and the writable side of duplex streams.
+ *
+ * Besides defining a few methods, this interface also implements the
+ * `EventEmitterInterface` which allows you to react to certain events:
+ *
+ * drain event:
+ *     The `drain` event will be emitted whenever the write buffer became full
+ *     previously and is now ready to accept more data.
+ *
+ *     ```php
+ *     $stream->on('drain', function () use ($stream) {
+ *         echo 'Stream is now ready to accept more data';
+ *     });
+ *     ```
+ *
+ *     This event SHOULD be emitted once every time the buffer became full
+ *     previously and is now ready to accept more data.
+ *     In other words, this event MAY be emitted any number of times, which may
+ *     be zero times if the buffer never became full in the first place.
+ *     This event SHOULD NOT be emitted if the buffer has not become full
+ *     previously.
+ *
+ *     This event is mostly used internally, see also `write()` for more details.
+ *
+ * pipe event:
+ *     The `pipe` event will be emitted whenever a readable stream is `pipe()`d
+ *     into this stream.
+ *     The event receives a single `ReadableStreamInterface` argument for the
+ *     source stream.
+ *
+ *     ```php
+ *     $stream->on('pipe', function (ReadableStreamInterface $source) use ($stream) {
+ *         echo 'Now receiving piped data';
+ *
+ *         // explicitly close target if source emits an error
+ *         $source->on('error', function () use ($stream) {
+ *             $stream->close();
+ *         });
+ *     });
+ *
+ *     $source->pipe($stream);
+ *     ```
+ *
+ *     This event MUST be emitted once for each readable stream that is
+ *     successfully piped into this destination stream.
+ *     In other words, this event MAY be emitted any number of times, which may
+ *     be zero times if no stream is ever piped into this stream.
+ *     This event MUST NOT be emitted if either the source is not readable
+ *     (closed already) or this destination is not writable (closed already).
+ *
+ *     This event is mostly used internally, see also `pipe()` for more details.
+ *
+ * error event:
+ *     The `error` event will be emitted once a fatal error occurs, usually while
+ *     trying to write to this stream.
+ *     The event receives a single `Exception` argument for the error instance.
+ *
+ *     ```php
+ *     $stream->on('error', function (Exception $e) {
+ *         echo 'Error: ' . $e->getMessage() . PHP_EOL;
+ *     });
+ *     ```
+ *
+ *     This event SHOULD be emitted once the stream detects a fatal error, such
+ *     as a fatal transmission error.
+ *     It SHOULD NOT be emitted after a previous `error` or `close` event.
+ *     It MUST NOT be emitted if this is not a fatal error condition, such as
+ *     a temporary network issue that did not cause any data to be lost.
+ *
+ *     After the stream errors, it MUST close the stream and SHOULD thus be
+ *     followed by a `close` event and then switch to non-writable mode, see
+ *     also `close()` and `isWritable()`.
+ *
+ *     Many common streams (such as a TCP/IP connection or a file-based stream)
+ *     only deal with data transmission and may choose
+ *     to only emit this for a fatal transmission error once and will then
+ *     close (terminate) the stream in response.
+ *
+ *     If this stream is a `DuplexStreamInterface`, you should also notice
+ *     how the readable side of the stream also implements an `error` event.
+ *     In other words, an error may occur while either reading or writing the
+ *     stream which should result in the same error processing.
+ *
+ * close event:
+ *     The `close` event will be emitted once the stream closes (terminates).
+ *
+ *     ```php
+ *     $stream->on('close', function () {
+ *         echo 'CLOSED';
+ *     });
+ *     ```
+ *
+ *     This event SHOULD be emitted once or never at all, depending on whether
+ *     the stream ever terminates.
+ *     It SHOULD NOT be emitted after a previous `close` event.
+ *
+ *     After the stream is closed, it MUST switch to non-writable mode,
+ *     see also `isWritable()`.
+ *
+ *     This event SHOULD be emitted whenever the stream closes, irrespective of
+ *     whether this happens implicitly due to an unrecoverable error or
+ *     explicitly when either side closes the stream.
+ *
+ *     Many common streams (such as a TCP/IP connection or a file-based stream)
+ *     will likely choose to emit this event after flushing the buffer from
+ *     the `end()` method, after receiving a *successful* `end` event or after
+ *     a fatal transmission `error` event.
+ *
+ *     If this stream is a `DuplexStreamInterface`, you should also notice
+ *     how the readable side of the stream also implements a `close` event.
+ *     In other words, after receiving this event, the stream MUST switch into
+ *     non-writable AND non-readable mode, see also `isReadable()`.
+ *     Note that this event should not be confused with the `end` event.
+ *
+ * The event callback functions MUST be a valid `callable` that obeys strict
+ * parameter definitions and MUST accept event parameters exactly as documented.
+ * The event callback functions MUST NOT throw an `Exception`.
+ * The return value of the event callback functions will be ignored and has no
+ * effect, so for performance reasons you're recommended to not return any
+ * excessive data structures.
+ *
+ * Every implementation of this interface MUST follow these event semantics in
+ * order to be considered a well-behaving stream.
+ *
+ * > Note that higher-level implementations of this interface may choose to
+ *   define additional events with dedicated semantics not defined as part of
+ *   this low-level stream specification. Conformance with these event semantics
+ *   is out of scope for this interface, so you may also have to refer to the
+ *   documentation of such a higher-level implementation.

+     * the stream without waiting for any buffered data to be flushed.
+     * If there's still data in the buffer, this data SHOULD be discarded.
+     *
+     * ```php

+     * ```
+     *
+     * Once the stream is closed, it SHOULD emit a `close` event.
+     * Note that this event SHOULD NOT be emitted more than once, in particular
+     * if this method is called multiple times.
+     *
+     * After calling this method, the stream MUST switch into a non-writable
+     * mode, see also `isWritable()`.
+     * This means that no further writes are possible, so any additional
+     * `write()` or `end()` calls have no effect.
+     *

+     * $stream->end(); // NO-OP
+     * ```
+     *
+     * Note that this method should not be confused with the `end()` method.
+     * Unlike the `end()` method, this method does not take care of any existing
+     * buffers and simply discards any buffer contents.
+     * Likewise, this method may also be called after calling `end()` on a
+     * stream in order to stop waiting for the stream to flush its final data.
+     *
+     * ```php
+     * $stream->end();
+     * $loop->addTimer(1.0, function () use ($stream) {
+     *     $stream->close();
+     * });

+     *
+     * If this stream is a `DuplexStreamInterface`, you should also notice
+     * how the readable side of the stream also implements a `close()` method.
+     * In other words, after calling this method, the stream MUST switch into
+     * non-writable AND non-readable mode, see also `isReadable()`.
+     *

+# PSR-7 Message Implementation
+
+This repository contains a partial [PSR-7](http://www.php-fig.org/psr/psr-7/)
+message implementation, several stream decorators, and some helpful
+functionality like query string parsing.  Currently missing
+ServerRequestInterface and UploadedFileInterface; a pull request for these features is welcome.
+
+
+# Stream implementation
+
+This package comes with a number of stream implementations and stream
+decorators.
+
+
+## AppendStream
+
+`RingCentral\Psr7\AppendStream`
+
+Reads from multiple streams, one after the other.
+
+```php
+use RingCentral\Psr7;
+
+$a = Psr7\stream_for('abc, ');
+$b = Psr7\stream_for('123.');
+$composed = new Psr7\AppendStream([$a, $b]);
+
+$composed->addStream(Psr7\stream_for(' Above all listen to me').
+
+echo $composed(); // abc, 123. Above all listen to me.
+```
+
+
+## BufferStream
+
+`RingCentral\Psr7\BufferStream`
+
+Provides a buffer stream that can be written to to fill a buffer, and read
+from to remove bytes from the buffer.
+
+This stream returns a "hwm" metadata value that tells upstream consumers
+what the configured high water mark of the stream is, or the maximum
+preferred size of the buffer.
+
+```php
+use RingCentral\Psr7;
+
+// When more than 1024 bytes are in the buffer, it will begin returning
+// false to writes. This is an indication that writers should slow down.
+$buffer = new Psr7\BufferStream(1024);
+```
+
+
+## CachingStream
+
+The CachingStream is used to allow seeking over previously read bytes on
+non-seekable streams. This can be useful when transferring a non-seekable
+entity body fails due to needing to rewind the stream (for example, resulting
+from a redirect). Data that is read from the remote stream will be buffered in
+a PHP temp stream so that previously read bytes are cached first in memory,
+then on disk.
+
+```php
+use RingCentral\Psr7;
+
+$original = Psr7\stream_for(fopen('http://www.google.com', 'r'));
+$stream = new Psr7\CachingStream($original);
+
+$stream->read(1024);
+echo $stream->tell();
+// 1024
+
+$stream->seek(0);
+echo $stream->tell();
+// 0
+```
+
+
+## DroppingStream
+
+`RingCentral\Psr7\DroppingStream`
+
+Stream decorator that begins dropping data once the size of the underlying
+stream becomes too full.
+
+```php
+use RingCentral\Psr7;
+
+// Create an empty stream
+$stream = Psr7\stream_for();
+
+// Start dropping data when the stream has more than 10 bytes
+$dropping = new Psr7\DroppingStream($stream, 10);
+
+$stream->write('01234567890123456789');
+echo $stream; // 0123456789
+```
+
+
+## FnStream
+
+`RingCentral\Psr7\FnStream`
+
+Compose stream implementations based on a hash of functions.
+
+Allows for easy testing and extension of a provided stream without needing to
+to create a concrete class for a simple extension point.
+
+```php
+
+use RingCentral\Psr7;
+
+$stream = Psr7\stream_for('hi');
+$fnStream = Psr7\FnStream::decorate($stream, [
+    'rewind' => function () use ($stream) {
+        echo 'About to rewind - ';
+        $stream->rewind();
+        echo 'rewound!';
+    }
+]);
+
+$fnStream->rewind();
+// Outputs: About to rewind - rewound!
+```
+
+
+## InflateStream
+
+`RingCentral\Psr7\InflateStream`
+
+Uses PHP's zlib.inflate filter to inflate deflate or gzipped content.
+
+This stream decorator skips the first 10 bytes of the given stream to remove
+the gzip header, converts the provided stream to a PHP stream resource,
+then appends the zlib.inflate filter. The stream is then converted back
+to a Guzzle stream resource to be used as a Guzzle stream.
+
+
+## LazyOpenStream
+
+`RingCentral\Psr7\LazyOpenStream`
+
+Lazily reads or writes to a file that is opened only after an IO operation
+take place on the stream.
+
+```php
+use RingCentral\Psr7;
+
+$stream = new Psr7\LazyOpenStream('/path/to/file', 'r');
+// The file has not yet been opened...
+
+echo $stream->read(10);
+// The file is opened and read from only when needed.
+```
+
+
+## LimitStream
+
+`RingCentral\Psr7\LimitStream`
+
+LimitStream can be used to read a subset or slice of an existing stream object.
+This can be useful for breaking a large file into smaller pieces to be sent in
+chunks (e.g. Amazon S3's multipart upload API).
+
+```php
+use RingCentral\Psr7;
+
+$original = Psr7\stream_for(fopen('/tmp/test.txt', 'r+'));
+echo $original->getSize();
+// >>> 1048576
+
+// Limit the size of the body to 1024 bytes and start reading from byte 2048
+$stream = new Psr7\LimitStream($original, 1024, 2048);
+echo $stream->getSize();
+// >>> 1024
+echo $stream->tell();
+// >>> 0
+```
+
+
+## MultipartStream
+
+`RingCentral\Psr7\MultipartStream`
+
+Stream that when read returns bytes for a streaming multipart or
+multipart/form-data stream.
+
+
+## NoSeekStream
+
+`RingCentral\Psr7\NoSeekStream`
+
+NoSeekStream wraps a stream and does not allow seeking.
+
+```php
+use RingCentral\Psr7;
+
+$original = Psr7\stream_for('foo');
+$noSeek = new Psr7\NoSeekStream($original);
+
+echo $noSeek->read(3);
+// foo
+var_export($noSeek->isSeekable());
+// false
+$noSeek->seek(0);
+var_export($noSeek->read(3));
+// NULL
+```
+
+
+## PumpStream
+
+`RingCentral\Psr7\PumpStream`
+
+Provides a read only stream that pumps data from a PHP callable.
+
+When invoking the provided callable, the PumpStream will pass the amount of
+data requested to read to the callable. The callable can choose to ignore
+this value and return fewer or more bytes than requested. Any extra data
+returned by the provided callable is buffered internally until drained using
+the read() function of the PumpStream. The provided callable MUST return
+false when there is no more data to read.
+
+
+## Implementing stream decorators
+
+Creating a stream decorator is very easy thanks to the
+`RingCentral\Psr7\StreamDecoratorTrait`. This trait provides methods that
+implement `Psr\Http\Message\StreamInterface` by proxying to an underlying
+stream. Just `use` the `StreamDecoratorTrait` and implement your custom
+methods.
+
+For example, let's say we wanted to call a specific function each time the last
+byte is read from a stream. This could be implemented by overriding the
+`read()` method.
+
+```php
+use Psr\Http\Message\StreamInterface;
+use RingCentral\Psr7\StreamDecoratorTrait;
+
+class EofCallbackStream implements StreamInterface
+{
+    use StreamDecoratorTrait;
+
+    private $callback;
+
+    public function __construct(StreamInterface $stream, callable $cb)
+    {
+        $this->stream = $stream;
+        $this->callback = $cb;
+    }
+
+    public function read($length)
+    {
+        $result = $this->stream->read($length);
+
+        // Invoke the callback when EOF is hit.
+        if ($this->eof()) {
+            call_user_func($this->callback);
+        }
+
+        return $result;
+    }
+}
+```
+
+This decorator could be added to any existing stream and used like so:
+
+```php
+use RingCentral\Psr7;
+
+$original = Psr7\stream_for('foo');
+
+$eofStream = new EofCallbackStream($original, function () {
+    echo 'EOF!';
+});
+
+$eofStream->read(2);
+$eofStream->read(1);
+// echoes "EOF!"
+$eofStream->seek(0);
+$eofStream->read(3);
+// echoes "EOF!"
+```
+
+
+## PHP StreamWrapper
+
+You can use the `RingCentral\Psr7\StreamWrapper` class if you need to use a
+PSR-7 stream as a PHP stream resource.
+
+Use the `RingCentral\Psr7\StreamWrapper::getResource()` method to create a PHP
+stream from a PSR-7 stream.
+
+```php
+use RingCentral\Psr7\StreamWrapper;
+
+$stream = RingCentral\Psr7\stream_for('hello!');
+$resource = StreamWrapper::getResource($stream);
+echo fread($resource, 6); // outputs hello!
+```
+
+
+# Function API
+
+There are various functions available under the `RingCentral\Psr7` namespace.
+
+
+## `function str`
+
+`function str(MessageInterface $message)`
+
+Returns the string representation of an HTTP message.
+
+```php
+$request = new RingCentral\Psr7\Request('GET', 'http://example.com');
+echo RingCentral\Psr7\str($request);
+```
+
+
+## `function uri_for`
+
+`function uri_for($uri)`
+
+This function accepts a string or `Psr\Http\Message\UriInterface` and returns a
+UriInterface for the given value. If the value is already a `UriInterface`, it
+is returned as-is.
+
+```php
+$uri = RingCentral\Psr7\uri_for('http://example.com');
+assert($uri === RingCentral\Psr7\uri_for($uri));
+```
+
+
+## `function stream_for`
+
+`function stream_for($resource = '', array $options = [])`
+
+Create a new stream based on the input type.
+
+Options is an associative array that can contain the following keys:
+
+* - metadata: Array of custom metadata.
+* - size: Size of the stream.
+
+This method accepts the following `$resource` types:
+
+- `Psr\Http\Message\StreamInterface`: Returns the value as-is.
+- `string`: Creates a stream object that uses the given string as the contents.
+- `resource`: Creates a stream object that wraps the given PHP stream resource.
+- `Iterator`: If the provided value implements `Iterator`, then a read-only
+  stream object will be created that wraps the given iterable. Each time the
+  stream is read from, data from the iterator will fill a buffer and will be
+  continuously called until the buffer is equal to the requested read size.
+  Subsequent read calls will first read from the buffer and then call `next`
+  on the underlying iterator until it is exhausted.
+- `object` with `__toString()`: If the object has the `__toString()` method,
+  the object will be cast to a string and then a stream will be returned that
+  uses the string value.
+- `NULL`: When `null` is passed, an empty stream object is returned.
+- `callable` When a callable is passed, a read-only stream object will be
+  created that invokes the given callable. The callable is invoked with the
+  number of suggested bytes to read. The callable can return any number of
+  bytes, but MUST return `false` when there is no more data to return. The
+  stream object that wraps the callable will invoke the callable until the
+  number of requested bytes are available. Any additional bytes will be
+  buffered and used in subsequent reads.
+
+```php
+$stream = RingCentral\Psr7\stream_for('foo');
+$stream = RingCentral\Psr7\stream_for(fopen('/path/to/file', 'r'));
+
+$generator function ($bytes) {
+    for ($i = 0; $i < $bytes; $i++) {
+        yield ' ';
+    }
+}
+
+$stream = RingCentral\Psr7\stream_for($generator(100));
+```
+
+
+## `function parse_header`
+
+`function parse_header($header)`
+
+Parse an array of header values containing ";" separated data into an array of
+associative arrays representing the header key value pair data of the header.
+When a parameter does not contain a value, but just contains a key, this
+function will inject a key with a '' string value.
+
+
+## `function normalize_header`
+
+`function normalize_header($header)`
+
+Converts an array of header values that may contain comma separated headers
+into an array of headers with no comma separated values.
+
+
+## `function modify_request`
+
+`function modify_request(RequestInterface $request, array $changes)`
+
+Clone and modify a request with the given changes. This method is useful for
+reducing the number of clones needed to mutate a message.
+
+The changes can be one of:
+
+- method: (string) Changes the HTTP method.
+- set_headers: (array) Sets the given headers.
+- remove_headers: (array) Remove the given headers.
+- body: (mixed) Sets the given body.
+- uri: (UriInterface) Set the URI.
+- query: (string) Set the query string value of the URI.
+- version: (string) Set the protocol version.
+
+
+## `function rewind_body`
+
+`function rewind_body(MessageInterface $message)`
+
+Attempts to rewind a message body and throws an exception on failure. The body
+of the message will only be rewound if a call to `tell()` returns a value other
+than `0`.
+
+
+## `function try_fopen`
+
+`function try_fopen($filename, $mode)`
+
+Safely opens a PHP stream resource using a filename.
+
+When fopen fails, PHP normally raises a warning. This function adds an error
+handler that checks for errors and throws an exception instead.
+
+
+## `function copy_to_string`
+
+`function copy_to_string(StreamInterface $stream, $maxLen = -1)`
+
+Copy the contents of a stream into a string until the given number of bytes
+have been read.
+
+
+## `function copy_to_stream`
+
+`function copy_to_stream(StreamInterface $source, StreamInterface $dest, $maxLen = -1)`
+
+Copy the contents of a stream into another stream until the given number of
+bytes have been read.
+
+
+## `function hash`
+
+`function hash(StreamInterface $stream, $algo, $rawOutput = false)`
+
+Calculate a hash of a Stream. This method reads the entire stream to calculate
+a rolling hash (based on PHP's hash_init functions).
+
+
+## `function readline`
+
+`function readline(StreamInterface $stream, $maxLength = null)`
+
+Read a line from the stream up to the maximum allowed buffer length.
+
+
+## `function parse_request`
+
+`function parse_request($message)`
+
+Parses a request message string into a request object.
+
+
+## `function parse_server_request`
+
+`function parse_server_request($message, array $serverParams = array())`
+
+Parses a request message string into a server-side request object.
+
+
+## `function parse_response`
+
+`function parse_response($message)`
+
+Parses a response message string into a response object.
+
+
+## `function parse_query`
+
+`function parse_query($str, $urlEncoding = true)`
+
+Parse a query string into an associative array.
+
+If multiple values are found for the same key, the value of that key value pair
+will become an array. This function does not parse nested PHP style arrays into
+an associative array (e.g., `foo[a]=1&foo[b]=2` will be parsed into
+`['foo[a]' => '1', 'foo[b]' => '2']`).
+
+
+## `function build_query`
+
+`function build_query(array $params, $encoding = PHP_QUERY_RFC3986)`
+
+Build a query string from an array of key value pairs.
+
+This function can use the return value of parseQuery() to build a query string.
+This function does not modify the provided keys when an array is encountered
+(like http_build_query would).
+
+
+## `function mimetype_from_filename`
+
+`function mimetype_from_filename($filename)`
+
+Determines the mimetype of a file by looking at its extension.
+
+
+## `function mimetype_from_extension`
+
+`function mimetype_from_extension($extension)`
+
+Maps a file extensions to a mimetype.
+
+
+# Static URI methods
+
+The `RingCentral\Psr7\Uri` class has several static methods to manipulate URIs.
+
+
+## `RingCentral\Psr7\Uri::removeDotSegments`
+
+`public static function removeDotSegments($path) -> UriInterface`
+
+Removes dot segments from a path and returns the new path.
+
+See http://tools.ietf.org/html/rfc3986#section-5.2.4
+
+
+## `RingCentral\Psr7\Uri::resolve`
+
+`public static function resolve(UriInterface $base, $rel) -> UriInterface`
+
+Resolve a base URI with a relative URI and return a new URI.
+
+See http://tools.ietf.org/html/rfc3986#section-5
+
+
+## `RingCentral\Psr7\Uri::withQueryValue`
+
+`public static function withQueryValue(UriInterface $uri, $key, $value) -> UriInterface`
+
+Create a new URI with a specific query string value.
+
+Any existing query string values that exactly match the provided key are
+removed and replaced with the given key value pair.
+
+Note: this function will convert "=" to "%3D" and "&" to "%26".
+
+
+## `RingCentral\Psr7\Uri::withoutQueryValue`
+
+`public static function withoutQueryValue(UriInterface $uri, $key, $value) -> UriInterface`
+
+Create a new URI with a specific query string value removed.
+
+Any existing query string values that exactly match the provided key are
+removed.
+
+Note: this function will convert "=" to "%3D" and "&" to "%26".
+
+
+## `RingCentral\Psr7\Uri::fromParts`
+
+`public static function fromParts(array $parts) -> UriInterface`
+
+Create a `RingCentral\Psr7\Uri` object from a hash of `parse_url` parts.
+

+# fbns-react
+
+A PHP client for the FBNS built on top of ReactPHP.
+
+## Requirements
+
+You need to install the [GMP extension](http://php.net/manual/en/book.gmp.php) to be able to run this code on x86 PHP builds.
+
+## Installation
+
+```sh
+composer require valga/fbns-react
+```
+
+## Basic Usage
+
+```php
+// Set up a FBNS client.
+$loop = \React\EventLoop\Factory::create();
+$client = new \Fbns\Client\Lite($loop);
+
+// Read saved credentials from a storage.
+$auth = new \Fbns\Client\Auth\DeviceAuth();
+try {
+    $auth->read($storage->get('fbns_auth'));
+} catch (\Exception $e) {
+}
+
+// Connect to a broker.
+$connection = new \Fbns\Client\Connection($deviceAuth, USER_AGENT);
+$client->connect(HOSTNAME, PORT, $connection);
+
+// Bind events.
+$client
+    ->on('connect', function (\Fbns\Client\Lite\ConnectResponsePacket $responsePacket) use ($client, $auth, $storage) {
+        // Update credentials and save them to a storage for future use.
+        try {
+            $auth->read($responsePacket->getAuth());
+            $storage->set('fbns_auth', $responsePacket->getAuth());
+        } catch (\Exception $e) {
+        }
+        
+        // Register an application.
+        $client->register(PACKAGE_NAME, APPLICATION_ID);
+    })
+    ->on('register', function (\Fbns\Client\Message\Register $message) use ($app) {
+        // Register received token with an application.
+        $app->registerPushToken($message->getToken());
+    })
+    ->on('push', function (\Fbns\Client\Message\Push $message) use ($app) {
+        // Handle received notification payload.
+        $app->handlePushNotification($message->getPayload());
+    });
+
+// Run main loop.
+$loop->run();
+```
+
+## Advanced Usage
+
+```php
+// Set up a proxy.
+$connector = new \React\Socket\Connector($loop);
+$proxy = new \Clue\React\HttpProxy('username:password@127.0.0.1:3128', $connector);
+
+// Disable SSL verification.
+$ssl = new \React\Socket\SecureConnector($proxy, $loop, ['verify_peer' => false, 'verify_peer_name' => false]);
+
+// Enable logging to stdout.
+$logger = new \Monolog\Logger('fbns');
+$logger->pushHandler(new \Monolog\Handler\StreamHandler('php://stdout', \Monolog\Logger::INFO));
+
+// Set up a client.
+$client = new \Fbns\Client\Lite($loop, $ssl, $logger);
+
+// Persistence.
+$client->on('disconnect', function () {
+    // Network connection has been closed. You can reestablish it if you want to.
+});
+$client->connect(HOSTNAME, PORT, $connection)
+    ->otherwise(function () {
+        // Connection attempt was unsuccessful, retry with an exponential backoff.
+    });
+```

+Winbox-Args
+===========
+
+[![Build Status](https://travis-ci.org/johnstevenson/winbox-args.svg?branch=master)](https://travis-ci.org/johnstevenson/winbox-args)
+[![Build status](https://ci.appveyor.com/api/projects/status/p4k75qqcyioj0mfl?svg=true)](https://ci.appveyor.com/project/johnstevenson/winbox-args)
+
+A PHP function to escape command-line arguments, which on Windows replaces `escapeshellarg` with a more robust method. Install from [Packagist][packagist] and use it like this:
+
+```php
+$escaped = Winbox\Args::escape($argument);
+```
+
+Alternatively, you can just [copy the code][function] into your own project (but please keep the license attribution and documentation link).
+
+### What it does
+The following transformations are made:
+
+* Double-quotes are escaped with a backslash, with any preceeding backslashes doubled up.
+* The argument is only enclosed in double-quotes if it contains whitespace or is empty.
+* Trailing backslashes are doubled up if the argument is enclosed in double-quotes.
+
+See [How Windows parses the command-line](https://github.com/johnstevenson/winbox-args/wiki/How-Windows-parses-the-command-line) if you would like to know why.
+
+By default, _cmd.exe_ meta characters are also escaped:
+
+* by caret-escaping the transformed argument (if it contains internal double-quotes or `%...%` syntax).
+* or by enclosing the argument in double-quotes.
+
+There are a couple limitations:
+
+1. If _cmd_ is started with _DelayedExpansion_ enabled, `!...!` syntax could expand environment variables.
+2. If the program name requires caret-escaping and contains whitespace, _cmd_ will not recognize it.
+
+See [How cmd.exe parses a command](https://github.com/johnstevenson/winbox-args/wiki/How-cmd.exe-parses-a-command) and [Implementing a solution](https://github.com/johnstevenson/winbox-args/wiki/Implementing-a-solution) for more information.
+
+### Is that it?
+Yup. An entire repo for a tiny function. However, it needs quite a lot of explanation because:
+
+* the command-line parsing rules in Windows are not immediately obvious.
+* PHP generally uses _cmd.exe_ to execute programs and this applies a different set of rules.
+* there is no simple solution.
+
+Full details explaining the different parsing rules, potential pitfalls and limitations can be found in the [Wiki][wiki].
