+# Ratchet
+
+[![Build Status](https://secure.travis-ci.org/ratchetphp/Ratchet.png?branch=master)](http://travis-ci.org/ratchetphp/Ratchet)
+[![Autobahn Testsuite](https://img.shields.io/badge/Autobahn-passing-brightgreen.svg)](http://socketo.me/reports/ab/index.html)
+[![Latest Stable Version](https://poser.pugx.org/cboden/ratchet/v/stable.png)](https://packagist.org/packages/cboden/ratchet)
+
+A PHP library for asynchronously serving WebSockets.
+Build up your application through simple interfaces and re-use your application without changing any of its code just by combining different components.
+
+## Requirements
+
+Shell access is required and root access is recommended.
+To avoid proxy/firewall blockage it's recommended WebSockets are requested on port 80 or 443 (SSL), which requires root access.
+In order to do this, along with your sync web stack, you can either use a reverse proxy or two separate machines.
+You can find more details in the [server conf docs](http://socketo.me/docs/deploy#serverconfiguration).
+
+### Documentation
+
+User and API documentation is available on Ratchet's website: http://socketo.me
+
+See https://github.com/cboden/Ratchet-examples for some out-of-the-box working demos using Ratchet.

+# 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.

+# CHANGELOG
+
+## 1.4.2 - 2017-03-20
+
+* 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
+
+* 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.
+* Added triggering of silenced deprecation warnings.
+
+## 1.4.0 - 2017-02-21
+
+* Fix `Stream::read` when length parameter <= 0.
+* `copy_to_stream` reads bytes in chunks instead of `maxLen` into memory.
+* Fix `ServerRequest::getUriFromGlobals` when `Host` header contains port.
+* 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'`
+* Fix compatibility of URIs with `file` scheme and empty host.
+* 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`
+* Deprecated `Uri::resolve` in favor of `UriResolver::resolve`
+* Deprecated `Uri::removeDotSegments` in favor of `UriResolver::removeDotSegments`
+
+## 1.3.1 - 2016-06-25
+
+* Fix `Uri::__toString` for network path references, e.g. `//example.org`.
+* Fix missing lowercase normalization for host.
+* Fix handling of URI components in case they are `'0'` in a lot of places,
+  e.g. as a user info password.
+* Fix `Uri::withAddedHeader` to correctly merge headers with different case.
+* Fix 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.
+* Fix `Uri::withAddedHeader` with an array of header values.
+* Fix `Uri::resolve` when base path has no slash and handling of fragment.
+* Fix 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.
+* Fix `ServerRequest::withoutAttribute` when attribute value is null.
+
+## 1.3.0 - 2016-04-13
+
+* Added remaining interfaces needed for full PSR7 compatibility
+  (ServerRequestInterface, UploadedFileInterface, etc.).
+* Added support for stream_for from scalars.
+* 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`.
+* Fixed handling of gzipped responses with FNAME headers.
+
+## 1.2.2 - 2016-01-22
+
+* Added support for URIs without any authority.
+* Added support for HTTP 451 'Unavailable For Legal Reasons.'
+* Added support for using '0' as a filename.
+* Added support for including non-standard ports in Host headers.
+
+## 1.2.1 - 2015-11-02
+
+* Now supporting negative offsets when seeking to SEEK_END.
+
+## 1.2.0 - 2015-08-15
+
+* 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
+
+* 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::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.

+# Contribution Guidelines
+This project is wide open to contributions.  You can use GitHub to [report
+issues][issues] or [submit pull requests][pull-requests].  When opening pull
+requests, it is recommended to follow these guidelines in order to grease the
+wheels, so to speak.
+
+Please include as many details as you can in any issues and pull requests.
+Understanding how you are using the library and exactly what problems you are
+having can also help make things move quickly.
+
+## Building
+There is an included [build script][build-script] that you can execute locally
+to run the code through the [PSR-1 coding standard][psr-1] and the
+[PHPUnit][phpunit] test suite.  Code coverage is kept at 100% according to
+PHPUnit's code coverage report.  This is inforced using
+[coveralls][coveralls].
+
+Alternatively, you can use [Docker][docker] and/or [Docker
+Compose][docker-compose] to execute the build:
+```bash
+docker-compose run build
+```
+
+## Automated builds
+Pull requests will automatically have a build kicked off on [Travis
+CI][travis-ci] and [Scrutinizer CI][scrutinizer-ci].  The results of these
+builds are monitored closely for all pull requests.

+
+## Requirements
+This library requires PHP 5.6, or newer.
+
+## Installation
+This package uses [composer](https://getcomposer.org) so you can just add
+`nubs/random-name-generator` as a dependency to your `composer.json` file or
+execute the following command:
+
+```bash
+composer require nubs/random-name-generator
+```
+
+## Generators
+
+### All
+The "all" generator will utilize all other configured generators to generate
+random names.  It will select from the list of generators randomly and then
+use them to generate a random name using their functionality.
+
+#### Usage
+```php
+$generator = \Nubs\RandomNameGenerator\All::create();
+echo $generator->getName();
+```
+
+Alternatively, if you want to configure/build the generators to use instead of
+using all of the available generators, you can construct them yourself:
+
+```php
+$generator = new \Nubs\RandomNameGenerator\All(
+    [
+        new \Nubs\RandomNameGenerator\Alliteration(),
+        new \Nubs\RandomNameGenerator\Vgng()
+    ]
+);
+```
+
+### Video Game Names
+The video game name generator is based off of [prior](http://videogamena.me/)
+[art](https://github.com/nullpuppy/vgng).  It will generate unique names based
+off of "typical" video games.
+
+#### Examples
+* *Kamikaze Bubblegum Warrior*
+* *Rockin' Valkyrie Gaiden*
+* *Neurotic Jackhammer Detective*
+* *My Little Mountain Climber Conflict*
+* *Small-Time Princess vs. The Space Mutants*
+
+You can also use [this web example](http://sam.sbat.com/) to see more example
+video game names generated by this library.
+
+#### Usage
+```php
+$generator = new \Nubs\RandomNameGenerator\Vgng();
+echo $generator->getName();
+```
+
+## Alliterative Names
+The alliteration name generator is based off of a list of
+[adjectives](http://grammar.yourdictionary.com/parts-of-speech/adjectives/list-of-adjective-words.html)
+and a list of [animals](https://animalcorner.co.uk/animals/).
+
+#### Examples
+* *Agreeable Anaconda*
+* *Disturbed Duck*
+* *Misty Meerkat*
+* *Prickly Pig*
+
+#### Usage
+```php
+$generator = new \Nubs\RandomNameGenerator\Alliteration();
+echo $generator->getName();
+```

+# 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.

+[![Build Status](https://travis-ci.org/ratchetphp/RFC6455.svg?branch=master)](https://travis-ci.org/ratchetphp/RFC6455)
+![Autobahn Testsuite](https://img.shields.io/badge/Autobahn-passing-brightgreen.svg)
+
+This library a protocol handler for the RFC6455 specification.
+It contains components for both server and client side handshake and messaging protocol negotation.
+
+Aspects that are left open to interpertation in the specification are also left open in this library.
+It is up to the implementation to determine how those interpertations are to be dealt with.
+
+This library is independent, framework agnostic, and does not deal with any I/O.
+HTTP upgrade negotiation integration points are handled with PSR-7 interfaces.

+# Cache Component
+
+[![Build Status](https://secure.travis-ci.org/reactphp/cache.png?branch=master)](http://travis-ci.org/reactphp/cache) [![Code Climate](https://codeclimate.com/github/reactphp/cache/badges/gpa.svg)](https://codeclimate.com/github/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.

+## 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()
+
+```php
+$cache
+    ->get('foo')
+    ->then('var_dump');
+```
+
+This example fetches the value of the key `foo` and passes it to the
+`var_dump` function. You can use any of the composition provided by
+[promises](https://github.com/reactphp/promise).
+
+If the key `foo` does not exist, the promise will be rejected.
+
+#### set()
+
+```php
+$cache->set('foo', 'bar');
+```
+
+This example eventually sets the value of the key `foo` to `bar`. If it
+already exists, it is overridden. No guarantees are made as to when the cache
+value is set. If the cache implementation has to go over the network to store
+it, it may take a while.
+
+#### remove()
+
+```php
+$cache->remove('foo');
+```
+
+This example eventually removes the key `foo` from the cache. As with `set`,
+this may not happen instantly.
+
+### ArrayCache
+
+The `ArrayCache` provides an in-memory implementation of the
+[`CacheInterface`](#cacheinterface).
+
+```php
+$cache = new ArrayCache();
+
+$cache->set('foo', 'bar');
+```
+
+## Common usage
+
+### Fallback get
+
+A common use case of caches is to attempt fetching a cached value and as a
+fallback retrieve it from the original data source if not found. Here is an
+example of that:
+
+```php
+$cache
+    ->get('foo')
+    ->then(null, 'getFooFromDb')
+    ->then('var_dump');
+```
+
+First an attempt is made to retrieve the value of `foo`. A promise rejection
+handler of the function `getFooFromDb` is registered. `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
+$cache
+    ->get('foo')
+    ->then(null, array($this, 'getAndCacheFooFromDb'))
+    ->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 $foo;
+}
+```
+
+By using chaining you can easily conditionally cache the value if it is
+fetched from the database.
+
+## Install
+
+The recommended way to install this library is [through Composer](https://getcomposer.org).
+[New to Composer?](https://getcomposer.org/doc/00-intro.md)
+
+This will install the latest supported version:
+
+```bash
+$ composer require react/cache:^0.4.2
+```
+
+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

+# Changelog
+
+## 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)

+    (#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:
+

+        echo 'IP: ' . $ip;
+    });
+    ```

+# 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.

+* [License](#license)
+* [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.
+
+Pending DNS queries can be cancelled by cancelling its pending promise like so:
+
+```php
+$promise = $resolver->resolve('reactphp.org');
+
+$promise->cancel();
+```
+
+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, $cache);
+```
+
+See also the wiki for possible [cache implementations](https://github.com/reactphp/react/wiki/Users#cache-implementations).
+
+## Advanced Usage
+
+For more advanced usages one can utilize the `React\Dns\Query\Executor` directly.
+The following example looks up the `IPv6` address for `igor.io`.
+
+```php
+$loop = Factory::create();
+
+$executor = new Executor($loop, new Parser(), new BinaryDumper(), null);
+
+$executor->query(
+    '8.8.8.8:53', 
+    new Query($name, Message::TYPE_AAAA, Message::CLASS_IN, time())
+)->done(function (Message $message) {
+    foreach ($message->answers as $answer) {
+        echo 'IPv6: ' . $answer->data . PHP_EOL;
+    }
+}, 'printf');
+
+$loop->run();
+
+```
+
+See also the [fourth example](examples).
+
+### HostsFileExecutor
+
+Note that the above `Executor` 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 Executor($loop, new Parser(), new BinaryDumper(), null);
+$executor = new HostsFileExecutor($hosts, $executor);
+
+$executor->query(
+    '8.8.8.8:53', 
+    new Query('localhost', Message::TYPE_A, Message::CLASS_IN, time())
+);
+```
+
+## 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:^0.4.13
+```
+
+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
+```

+# Changelog
+
+## 0.5.1 (2018-04-09)
+
+* New loop: ExtEvLoop (PECL ext-ev)  (#148 by @kaduev13)
+
+## 0.5.0 (2018-04-05)
+
+A major feature release with a significant documentation overhaul and long overdue API cleanup!
+
+This update involves a number of BC breaks due to dropped support for deprecated
+functionality. We've tried hard to avoid BC breaks where possible and minimize
+impact otherwise. We expect that most consumers of this package will actually
+not be affected by any BC breaks, see below for more details.
+
+We realize that the changes listed below may seem overwhelming, but we've tried
+to be very clear about any possible BC breaks. Don't worry: In fact, all ReactPHP
+components are already compatible and support both this new release as well as
+providing backwards compatibility with the last release.
+
+*   Feature / BC break: Add support for signal handling via new
+    `LoopInterface::addSignal()` and `LoopInterface::removeSignal()` methods.
+    (#104 by @WyriHaximus and #111 and #150 by @clue)
+
+    ```php
+    $loop->addSignal(SIGINT, function () {
+        echo 'CTRL-C';
+    });
+    ```
+
+*   Feature: Significant documentation updates for `LoopInterface` and `Factory`.
+    (#100, #119, #126, #127, #159 and #160 by @clue, #113 by @WyriHaximus and #81 and #91 by @jsor)
+
+*   Feature: Add examples to ease getting started
+    (#99, #100 and #125 by @clue, #59 by @WyriHaximus and #143 by @jsor)
+
+*   Feature: Documentation for advanced timer concepts, such as monotonic time source vs wall-clock time
+    and high precision timers with millisecond accuracy or below.
+    (#130 and #157 by @clue)
+
+*   Feature: Documentation for advanced stream concepts, such as edge-triggered event listeners
+    and stream buffers and allow throwing Exception if stream resource is not supported.
+    (#129 and #158 by @clue)
+
+*   Feature: Throw `BadMethodCallException` on manual loop creation when required extension isn't installed.
+    (#153 by @WyriHaximus)
+
+*   Feature / BC break: First class support for legacy PHP 5.3 through PHP 7.2 and HHVM
+    and remove all `callable` type hints for consistency reasons.
+    (#141 and #151 by @clue)
+
+*   BC break: Documentation for timer API and clean up unneeded timer API.
+    (#102 by @clue)
+
+    Remove `TimerInterface::cancel()`, use `LoopInterface::cancelTimer()` instead:
+
+    ```php
+    // old (method invoked on timer instance)
+    $timer->cancel();
+    
+    // already supported before: invoke method on loop instance
+    $loop->cancelTimer($timer);
+    ```
+
+    Remove unneeded `TimerInterface::setData()` and `TimerInterface::getData()`,
+    use closure binding to add arbitrary data to timer instead:
+
+    ```php
+    // old (limited setData() and getData() only allows single variable)
+    $name = 'Tester';
+    $timer = $loop->addTimer(1.0, function ($timer) {
+        echo 'Hello ' . $timer->getData() . PHP_EOL;
+    });
+    $timer->setData($name);
+
+    // already supported before: closure binding allows any number of variables
+    $name = 'Tester';
+    $loop->addTimer(1.0, function () use ($name) {
+        echo 'Hello ' . $name . PHP_EOL;
+    });
+    ```
+
+    Remove unneeded `TimerInterface::getLoop()`, use closure binding instead:
+
+    ```php
+    // old (getLoop() called on timer instance)
+    $loop->addTimer(0.1, function ($timer) {
+        $timer->getLoop()->stop();
+    });
+
+    // already supported before: use closure binding as usual
+    $loop->addTimer(0.1, function () use ($loop) {
+        $loop->stop();
+    });
+    ```
+
+*   BC break: Remove unneeded `LoopInterface::isTimerActive()` and
+    `TimerInterface::isActive()` to reduce API surface.
+    (#133 by @clue)
+
+    ```php
+    // old (method on timer instance or on loop instance)
+    $timer->isActive();
+    $loop->isTimerActive($timer);
+    ```
+
+*   BC break: Move `TimerInterface` one level up to `React\EventLoop\TimerInterface`.
+    (#138 by @WyriHaximus)
+
+    ```php
+    // old (notice obsolete "Timer" namespace)
+    assert($timer instanceof React\EventLoop\Timer\TimerInterface);
+
+    // new
+    assert($timer instanceof React\EventLoop\TimerInterface);
+    ```
+
+*   BC break: Remove unneeded `LoopInterface::nextTick()` (and internal `NextTickQueue`),
+    use `LoopInterface::futureTick()` instead.
+    (#30 by @clue)
+
+    ```php
+    // old (removed)
+    $loop->nextTick(function () {
+        echo 'tick';
+    });
+
+    // already supported before
+    $loop->futureTick(function () {
+        echo 'tick';
+    });
+    ```
+
+*   BC break: Remove unneeded `$loop` argument for `LoopInterface::futureTick()`
+    (and fix internal cyclic dependency).
+    (#103 by @clue)
+
+    ```php
+    // old ($loop gets passed by default)
+    $loop->futureTick(function ($loop) {
+        $loop->stop();
+    });
+
+    // already supported before: use closure binding as usual
+    $loop->futureTick(function () use ($loop) {
+        $loop->stop();
+    });
+    ```
+
+*   BC break: Remove unneeded `LoopInterface::tick()`.
+    (#72 by @jsor)
+
+    ```php
+    // old (removed)
+    $loop->tick();
+
+    // suggested work around for testing purposes only
+    $loop->futureTick(function () use ($loop) {
+        $loop->stop();
+    });
+    ```
+
+*   BC break: Documentation for advanced stream API and clean up unneeded stream API.
+    (#110 by @clue)
+
+    Remove unneeded `$loop` argument for `LoopInterface::addReadStream()`
+    and `LoopInterface::addWriteStream()`, use closure binding instead:
+
+    ```php
+    // old ($loop gets passed by default)
+    $loop->addReadStream($stream, function ($stream, $loop) {
+        $loop->removeReadStream($stream);
+    });
+
+    // already supported before: use closure binding as usual
+    $loop->addReadStream($stream, function ($stream) use ($loop) {
+        $loop->removeReadStream($stream);
+    });
+    ```
+
+*   BC break: Remove unneeded `LoopInterface::removeStream()` method,
+    use `LoopInterface::removeReadStream()` and `LoopInterface::removeWriteStream()` instead.
+    (#118 by @clue)
+
+    ```php
+    // old
+    $loop->removeStream($stream);
+
+    // already supported before
+    $loop->removeReadStream($stream);
+    $loop->removeWriteStream($stream);
+    ```
+
+*   BC break: Rename `LibEventLoop` to `ExtLibeventLoop` and `LibEvLoop` to `ExtLibevLoop`
+    for consistent naming for event loop implementations.
+    (#128 by @clue)
+
+*   BC break: Remove optional `EventBaseConfig` argument from `ExtEventLoop`
+    and make its `FEATURE_FDS` enabled by default.
+    (#156 by @WyriHaximus)
+
+*   BC break: Mark all classes as final to discourage inheritance.
+    (#131 by @clue)

+# EventLoop Component
+
+[![Build Status](https://travis-ci.org/reactphp/event-loop.svg?branch=master)](https://travis-ci.org/reactphp/event-loop)
+
+[ReactPHP](https://reactphp.org/)'s core reactor event loop 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()`](#run) call that is controlled by the user.

+
+## 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($server, false);
+
+$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);
+            $loop->removeWriteStream($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();
+```
+
+See also the [examples](examples).
+
+## 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()`](#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 [`$loop->run()`](#run) call at the end of the program.
+
+### Factory
+
+The `Factory` class exists as a convenient way to pick the best available
+[event loop implementation](#loop-implementations).
+
+#### create()
+
+The `create(): LoopInterface` method can be used to create a new event loop
+instance:
+
+```php
+$loop = React\EventLoop\Factory::create();
+```
+
+This method always returns an instance implementing [`LoopInterface`](#loopinterface),
+the actual [event loop implementation](#loop-implementations) is an implementation detail.
+
+This method should usually only be called once at the beginning of the program.
+
+### Loop implementations
+
+In addition to the [`LoopInterface`](#loopinterface), there are a number of
+event loop implementations provided.
+
+All of the event loops support these features:
+
+* File descriptor polling
+* One-off timers
+* Periodic timers
+* Deferred execution on future loop tick
+
+For most consumers of this package, the underlying event loop implementation is
+an implementation detail.
+You should use the [`Factory`](#factory) to automatically create a new instance.
+
+Advanced! If you explicitly need a certain event loop implementation, you can
+manually instantiate one of the following classes.
+Note that you may have to install the required PHP extensions for the respective
+event loop implementation first or they will throw a `BadMethodCallException` on creation.
+
+#### StreamSelectLoop
+
+A `stream_select()` based event loop.
+
+This uses the [`stream_select()`](http://php.net/manual/en/function.stream-select.php)
+function and is the only implementation which works out of the box with PHP.
+
+This event loop works out of the box on PHP 5.3 through PHP 7+ and HHVM.
+This means that no installation is required and this library works on all
+platforms and supported PHP versions.
+Accordingly, the [`Factory`](#factory) will use this event loop by default if
+you do not install any of the event loop extensions listed below.
+
+Under the hood, it does a simple `select` system call.
+This system call is limited to the maximum file descriptor number of
+`FD_SETSIZE` (platform dependent, commonly 1024) and scales with `O(m)`
+(`m` being the maximum file descriptor number passed).
+This means that you may run into issues when handling thousands of streams
+concurrently and you may want to look into using one of the alternative
+event loop implementations listed below in this case.
+If your use case is among the many common use cases that involve handling only
+dozens or a few hundred streams at once, then this event loop implementation
+performs really well.
+
+If you want to use signal handling (see also [`addSignal()`](#addsignal) below),
+this event loop implementation requires `ext-pcntl`.
+This extension is only available for Unix-like platforms and does not support
+Windows.
+It is commonly installed as part of many PHP distributions.
+If this extension is missing (or you're running on Windows), signal handling is
+not supported and throws a `BadMethodCallException` instead.
+
+This event loop is known to rely on wall-clock time to schedule future
+timers, because a monotonic time source is not available in PHP by default.
+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 schedule a timer to trigger in 30s and then adjust
+your system time forward by 20s, the timer may trigger in 10s.
+See also [`addTimer()`](#addtimer) for more details.
+
+#### ExtEventLoop
+
+An `ext-event` based event loop.
+
+This uses the [`event` PECL extension](https://pecl.php.net/package/event).
+It supports the same backends as libevent.
+
+This loop is known to work with PHP 5.4 through PHP 7+.
+
+#### ExtEvLoop
+
+An `ext-ev` based event loop.
+
+This loop uses the [`ev` PECL extension](https://pecl.php.net/package/ev), that
+provides an interface to `libev` library.
+
+This loop is known to work with PHP 5.4 through PHP 7+.
+
+
+#### ExtLibeventLoop
+
+An `ext-libevent` based event loop.
+
+This uses the [`libevent` PECL extension](https://pecl.php.net/package/libevent).
+`libevent` itself supports a number of system-specific backends (epoll, kqueue).
+
+This event loop does only work with PHP 5.
+An [unofficial update](https://github.com/php/pecl-event-libevent/pull/2) for
+PHP 7 does exist, but it is known to cause regular crashes due to `SEGFAULT`s.
+To reiterate: Using this event loop on PHP 7 is not recommended.
+Accordingly, the [`Factory`](#factory) will not try to use this event loop on
+PHP 7.
+
+This event loop is known to trigger a readable listener only if
+the stream *becomes* readable (edge-triggered) and may not trigger if the
+stream has already been readable from the beginning.
+This also implies that a stream may not be recognized as readable when data
+is still left in PHP's internal stream buffers.
+As such, it's recommended to use `stream_set_read_buffer($stream, 0);`
+to disable PHP's internal read buffer in this case.
+See also [`addReadStream()`](#addreadstream) for more details.
+
+#### ExtLibevLoop
+
+An `ext-libev` based event loop.
+
+This uses an [unofficial `libev` extension](https://github.com/m4rw3r/php-libev).
+It supports the same backends as libevent.
+
+This loop does only work with PHP 5.
+An update for PHP 7 is [unlikely](https://github.com/m4rw3r/php-libev/issues/8)
+to happen any time soon.
+
+### LoopInterface
+
+#### run()
+
+The `run(): void` method can be used to
+run the event loop until there are no more tasks to perform.
+
+For many applications, this method is the only directly visible
+invocation on the event loop.
+As a rule of thumb, it is usally recommended to attach everything to the
+same loop instance and then run the loop once at the bottom end of the
+application.
+
+```php
+$loop->run();
+```
+
+This method will keep the loop running until there are no more tasks
+to perform. In other words: This method will block until the last
+timer, stream and/or signal has been removed.
+
+Likewise, it is imperative to ensure the application actually invokes
+this method once. Adding listeners to the loop and missing to actually
+run it will result in the application exiting without actually waiting
+for any of the attached listeners.
+
+This method MUST NOT be called while the loop is already running.
+This method MAY be called more than once after it has explicity been
+[`stop()`ped](#stop) or after it automatically stopped because it
+previously did no longer have anything to do.
+
+#### stop()
+
+The `stop(): void` method can be used to
+instruct a running event loop to stop.
+
+This method is considered advanced usage and should be used with care.
+As a rule of thumb, it is usually recommended to let the loop stop
+only automatically when it no longer has anything to do.
+
+This method can be used to explicitly instruct the event loop to stop:
+
+```php
+$loop->addTimer(3.0, function () use ($loop) {
+    $loop->stop();
+});
+```
+
+Calling this method on a loop instance that is not currently running or
+on a loop instance that has already been stopped has no effect.
+
+#### addTimer()
+
+The `addTimer(float $interval, callable $callback): TimerInterface` method can be used to
+enqueue a callback to be invoked once after the given interval.
+
+The timer callback function MUST be able to accept a single parameter,
+the timer instance as also returned by this method or you MAY use a
+function which has no parameters at all.
+
+The timer callback function MUST NOT throw an `Exception`.
+The return value of the timer callback function will be ignored and has
+no effect, so for performance reasons you're recommended to not return
+any excessive data structures.
+
+Unlike [`addPeriodicTimer()`](#addperiodictimer), this method will ensure
+the callback will be invoked only once after the given interval.
+You can invoke [`cancelTimer`](#canceltimer) to cancel a pending timer.
+
+```php
+$loop->addTimer(0.8, function () {
+    echo 'world!' . PHP_EOL;
+});
+
+$loop->addTimer(0.3, function () {
+    echo 'hello ';
+});
+```
+
+See also [example #1](examples).
+
+If you want to access any variables within your callback function, you
+can bind arbitrary data to a callback closure like this:
+
+```php
+function hello($name, LoopInterface $loop)
+{
+    $loop->addTimer(1.0, function () use ($name) {
+        echo "hello $name\n";
+    });
+}
+
+hello('Tester', $loop);
+```
+
+This interface does not enforce any particular timer resolution, so
+special care may have to be taken if you rely on very high precision with
+millisecond accuracy or below. Event loop implementations SHOULD work on
+a best effort basis and SHOULD provide at least millisecond accuracy
+unless otherwise noted. Many existing event loop implementations are
+known to provide microsecond accuracy, but it's generally not recommended
+to rely on this high precision.
+
+Similarly, the execution order of timers scheduled to execute at the
+same time (within its possible accuracy) is not guaranteed.
+
+This interface suggests that event loop implementations SHOULD use a
+monotonic time source if available. Given that a monotonic time source is
+not available on PHP by default, event loop 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 schedule a timer to trigger in 30s and then adjust
+your system time forward by 20s, the timer SHOULD still trigger in 30s.
+See also [event loop implementations](#loop-implementations) for more details.
+
+#### addPeriodicTimer()
+
+The `addPeriodicTimer(float $interval, callable $callback): TimerInterface` method can be used to
+enqueue a callback to be invoked repeatedly after the given interval.
+
+The timer callback function MUST be able to accept a single parameter,
+the timer instance as also returned by this method or you MAY use a
+function which has no parameters at all.
+
+The timer callback function MUST NOT throw an `Exception`.
+The return value of the timer callback function will be ignored and has
+no effect, so for performance reasons you're recommended to not return
+any excessive data structures.
+
+Unlike [`addTimer()`](#addtimer), this method will ensure the the
+callback will be invoked infinitely after the given interval or until you
+invoke [`cancelTimer`](#canceltimer).
+
+```php
+$timer = $loop->addPeriodicTimer(0.1, function () {
+    echo 'tick!' . PHP_EOL;
+});
+
+$loop->addTimer(1.0, function () use ($loop, $timer) {
+    $loop->cancelTimer($timer);
+    echo 'Done' . PHP_EOL;
+});
+```
+
+See also [example #2](examples).
+
+If you want to limit the number of executions, you can bind
+arbitrary data to a callback closure like this:
+
+```php
+function hello($name, LoopInterface $loop)
+{
+    $n = 3;
+    $loop->addPeriodicTimer(1.0, function ($timer) use ($name, $loop, &$n) {
+        if ($n > 0) {
+            --$n;
+            echo "hello $name\n";
+        } else {
+            $loop->cancelTimer($timer);
+        }
+    });
+}
+
+hello('Tester', $loop);
+```
+
+This interface does not enforce any particular timer resolution, so
+special care may have to be taken if you rely on very high precision with
+millisecond accuracy or below. Event loop implementations SHOULD work on
+a best effort basis and SHOULD provide at least millisecond accuracy
+unless otherwise noted. Many existing event loop implementations are
+known to provide microsecond accuracy, but it's generally not recommended
+to rely on this high precision.
+
+Similarly, the execution order of timers scheduled to execute at the
+same time (within its possible accuracy) is not guaranteed.
+
+This interface suggests that event loop implementations SHOULD use a
+monotonic time source if available. Given that a monotonic time source is
+not available on PHP by default, event loop 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 schedule a timer to trigger in 30s and then adjust
+your system time forward by 20s, the timer SHOULD still trigger in 30s.
+See also [event loop implementations](#loop-implementations) for more details.
+
+Additionally, periodic timers may be subject to timer drift due to
+re-scheduling after each invocation. As such, it's generally not
+recommended to rely on this for high precision intervals with millisecond
+accuracy or below.
+
+#### cancelTimer()
+
+The `cancelTimer(TimerInterface $timer): void` method can be used to
+cancel a pending timer.
+
+See also [`addPeriodicTimer()`](#addperiodictimer) and [example #2](examples).
+
+Calling this method on a timer instance that has not been added to this
+loop instance or on a timer that has already been cancelled has no effect.
+
+#### futureTick()
+
+The `futureTick(callable $listener): void` method can be used to
+schedule a callback to be invoked on a future tick of the event loop.
+
+This works very much similar to timers with an interval of zero seconds,
+but does not require the overhead of scheduling a timer queue.
+
+The tick callback function MUST be able to accept zero parameters.
+
+The tick callback function MUST NOT throw an `Exception`.
+The return value of the tick callback function will be ignored and has
+no effect, so for performance reasons you're recommended to not return
+any excessive data structures.
+
+If you want to access any variables within your callback function, you
+can bind arbitrary data to a callback closure like this:
+
+```php
+function hello($name, LoopInterface $loop)
+{
+    $loop->futureTick(function () use ($name) {
+        echo "hello $name\n";
+    });
+}
+
+hello('Tester', $loop);
+```
+
+Unlike timers, tick callbacks are guaranteed to be executed in the order
+they are enqueued.
+Also, once a callback is enqueued, there's no way to cancel this operation.
+
+This is often used to break down bigger tasks into smaller steps (a form
+of cooperative multitasking).
+
+```php
+$loop->futureTick(function () {
+    echo 'b';
+});
+$loop->futureTick(function () {
+    echo 'c';
+});
+echo 'a';
+```
+
+See also [example #3](examples).
+
+#### addSignal()
+
+The `addSignal(int $signal, callable $listener): void` method can be used to
+register a listener to be notified when a signal has been caught by this process.
+
+This is useful to catch user interrupt signals or shutdown signals from
+tools like `supervisor` or `systemd`.
+
+The listener callback function MUST be able to accept a single parameter,
+the signal added by this method or you MAY use a function which
+has no parameters at all.
+
+The listener callback function MUST NOT throw an `Exception`.
+The return value of the listener callback function will be ignored and has
+no effect, so for performance reasons you're recommended to not return
+any excessive data structures.
+
+```php
+$loop->addSignal(SIGINT, function (int $signal) {
+    echo 'Caught user interrupt signal' . PHP_EOL;
+});
+```
+
+See also [example #4](examples).
+
+Signaling is only available on Unix-like platform, Windows isn't
+supported due to operating system limitations.
+This method may throw a `BadMethodCallException` if signals aren't
+supported on this platform, for example when required extensions are
+missing.
+
+**Note: A listener can only be added once to the same signal, any
+attempts to add it more then once will be ignored.**
+
+#### removeSignal()
+
+The `removeSignal(int $signal, callable $listener): void` method can be used to
+remove a previously added signal listener.
+
+```php
+$loop->removeSignal(SIGINT, $listener);
+```
+
+Any attempts to remove listeners that aren't registered will be ignored.
+
+#### addReadStream()
+
+> Advanced! Note that this low-level API is considered advanced usage.
+  Most use cases should probably use the higher-level
+  [readable Stream API](https://github.com/reactphp/stream#readablestreaminterface)
+  instead.
+
+The `addReadStream(resource $stream, callable $callback): void` method can be used to
+register a listener to be notified when a stream is ready to read.
+
+The first parameter MUST be a valid stream resource that supports
+checking whether it is ready to read by this loop implementation.
+A single stream resource MUST NOT be added more than once.
+Instead, either call [`removeReadStream()`](#removereadstream) first or
+react to this event with a single listener and then dispatch from this
+listener. This method MAY throw an `Exception` if the given resource type
+is not supported by this loop implementation.
+
+The listener callback function MUST be able to accept a single parameter,
+the stream resource added by this method or you MAY use a function which
+has no parameters at all.
+
+The listener callback function MUST NOT throw an `Exception`.
+The return value of the listener callback function will be ignored and has
+no effect, so for performance reasons you're recommended to not return
+any excessive data structures.
+
+If you want to access any variables within your callback function, you
+can bind arbitrary data to a callback closure like this:
+
+```php
+$loop->addReadStream($stream, function ($stream) use ($name) {
+    echo $name . ' said: ' . fread($stream);
+});
+```
+
+See also [example #11](examples).
+
+You can invoke [`removeReadStream()`](#removereadstream) to remove the
+read event listener for this stream.
+
+The execution order of listeners when multiple streams become ready at
+the same time is not guaranteed.
+
+Some event loop implementations are known to only trigger the listener if
+the stream *becomes* readable (edge-triggered) and may not trigger if the
+stream has already been readable from the beginning.
+This also implies that a stream may not be recognized as readable when data
+is still left in PHP's internal stream buffers.
+As such, it's recommended to use `stream_set_read_buffer($stream, 0);`
+to disable PHP's internal read buffer in this case.
+
+#### addWriteStream()
+
+> Advanced! Note that this low-level API is considered advanced usage.
+  Most use cases should probably use the higher-level
+  [writable Stream API](https://github.com/reactphp/stream#writablestreaminterface)
+  instead.
+
+The `addWriteStream(resource $stream, callable $callback): void` method can be used to
+register a listener to be notified when a stream is ready to write.
+
+The first parameter MUST be a valid stream resource that supports
+checking whether it is ready to write by this loop implementation.
+A single stream resource MUST NOT be added more than once.
+Instead, either call [`removeWriteStream()`](#removewritestream) first or
+react to this event with a single listener and then dispatch from this
+listener. This method MAY throw an `Exception` if the given resource type
+is not supported by this loop implementation.
+
+The listener callback function MUST be able to accept a single parameter,
+the stream resource added by this method or you MAY use a function which
+has no parameters at all.
+
+The listener callback function MUST NOT throw an `Exception`.
+The return value of the listener callback function will be ignored and has
+no effect, so for performance reasons you're recommended to not return
+any excessive data structures.
+
+If you want to access any variables within your callback function, you
+can bind arbitrary data to a callback closure like this:
+
+```php
+$loop->addWriteStream($stream, function ($stream) use ($name) {
+    fwrite($stream, 'Hello ' . $name);
+});
+```
+
+See also [example #12](examples).
+
+You can invoke [`removeWriteStream()`](#removewritestream) to remove the
+write event listener for this stream.
+
+The execution order of listeners when multiple streams become ready at
+the same time is not guaranteed.
+
+#### removeReadStream()
+
+The `removeReadStream(resource $stream): void` method can be used to
+remove the read event listener for the given stream.
+
+Removing a stream from the loop that has already been removed or trying
+to remove a stream that was never added or is invalid has no effect.
+
+#### removeWriteStream()
+
+The `removeWriteStream(resource $stream): void` method can be used to
+remove the write event listener for the given stream.
+
+Removing a stream from the loop that has already been removed or trying
+to remove a stream that was never added or is invalid has no effect.
+

+ * To reiterate: Using this event loop on PHP 7 is not recommended.
+ * Accordingly, the [`Factory`](#factory) will not try to use this event loop on

+ *
+ * This event loop is known to trigger a readable listener only if
+ * the stream *becomes* readable (edge-triggered) and may not trigger if the
+ * stream has already been readable from the beginning.
+ * This also implies that a stream may not be recognized as readable when data
+ * is still left in PHP's internal stream buffers.
+ * As such, it's recommended to use `stream_set_read_buffer($stream, 0);`
+ * to disable PHP's internal read buffer in this case.

+ * A `stream_select()` based event loop.
+ *
+ * This uses the [`stream_select()`](http://php.net/manual/en/function.stream-select.php)
+ * function and is the only implementation which works out of the box with PHP.
+ *
+ * This event loop works out of the box on PHP 5.4 through PHP 7+ and HHVM.
+ * This means that no installation is required and this library works on all
+ * platforms and supported PHP versions.
+ * Accordingly, the [`Factory`](#factory) will use this event loop by default if
+ * you do not install any of the event loop extensions listed below.
+ *
+ * Under the hood, it does a simple `select` system call.
+ * This system call is limited to the maximum file descriptor number of
+ * `FD_SETSIZE` (platform dependent, commonly 1024) and scales with `O(m)`
+ * (`m` being the maximum file descriptor number passed).
+ * This means that you may run into issues when handling thousands of streams
+ * concurrently and you may want to look into using one of the alternative
+ * event loop implementations listed below in this case.
+ * If your use case is among the many common use cases that involve handling only
+ * dozens or a few hundred streams at once, then this event loop implementation
+ * performs really well.
+ *
+ * If you want to use signal handling (see also [`addSignal()`](#addsignal) below),
+ * this event loop implementation requires `ext-pcntl`.
+ * This extension is only available for Unix-like platforms and does not support
+ * Windows.
+ * It is commonly installed as part of many PHP distributions.
+ * If this extension is missing (or you're running on Windows), signal handling is
+ * not supported and throws a `BadMethodCallException` instead.
+ *
+ * This event loop is known to rely on wall-clock time to schedule future
+ * timers, because a monotonic time source is not available in PHP by default.
+ * 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 schedule a timer to trigger in 30s and then adjust
+ * your system time forward by 20s, the timer may trigger in 10s.
+ * See also [`addTimer()`](#addtimer) for more details.

+
+## 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 timout 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
+=================
+
+* 2.5.1 (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
+------------
+
+React/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 $update = null);
+```
+
+The `promise` method returns the promise of the deferred.
+
+The `resolve` and `reject` methods control the state of the deferred.
+
+The `notify` method is for progress notification.
+
+The constructor of the `Deferred` accepts an optional `$canceller` argument.
+See [Promise](#promise-1) 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 `$reason` itself is a promise, the promise will be rejected with the outcome
+of this promise regardless whether it fulfills or rejects.
+
+#### Deferred::notify()
+
+```php
+$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-1)
+* [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` 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` 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()
+
+```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
+    // along the way if you want/need.
+
+    $resolve($awesomeResult);
+    // or $resolve($anotherPromise);
+    // or $reject($nastyError);
+    // or $notify($progressNotification);
+};
+
+$canceller = function (callable $resolve, callable $reject, callable $progress) {
+    // Cancel/abort any running operations like network connections, streams etc.
+
+    $reject(new \Exception('Promise cancelled'));
+};
+
+$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.
+  * `$notify($update)` - 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 = 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
+
+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
+
+## 0.8.10 (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

+# 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);

+    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:
+

+    '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:^0.8.10
+```
+
+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
+```

+ * The `SecureServer` class implements the `ServerInterface` and is responsible

+ * It does so by wrapping a `TcpServer` instance which waits for plaintext
+ * TCP/IP connections and then performs a TLS handshake for each connection.
+ *
+ * ```php
+ * $server = new TcpServer(8000, $loop);
+ * $server = new SecureServer($server, $loop, array(
+ *     // tls context options here…
+ * ));
+ * ```
+ *
+ * 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` 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

+     * It does so by wrapping a `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],

+     * 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'
+     * ));
+     * ```
+     *
+     * 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
+     * then close the underlying connection.

+ *
+ * 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;
+ *     });
+ *     ```

+     * ```php

+     * ```

+     *
+     * 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`:
+     *

+## 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)
+
+*   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

+# 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.
+
+## 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/stream:^0.7.7
+```
+
+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 due to its vast
+performance improvements.
+
+## 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 `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 `ThroughStream` implements the

+ * 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->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) {

+ *         throw new \UnexpectedValueException('Only strings allowed');

+/**
+ * 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.

+     * If the internal buffer is full after adding `$data`, then `write()`

+CHANGELOG
+=========
+
+3.4.0
+-----
+
+ * implemented PHP 7.0's `SessionUpdateTimestampHandlerInterface` with a new
+   `AbstractSessionHandler` base class and a new `StrictSessionHandler` wrapper
+ * deprecated the `WriteCheckSessionHandler`, `NativeSessionHandler` and `NativeProxy` classes
+ * deprecated setting session save handlers that do not implement `\SessionHandlerInterface` in `NativeSessionStorage::setSaveHandler()`
+ * deprecated using `MongoDbSessionHandler` with the legacy mongo extension; use it with the mongodb/mongodb package and ext-mongodb instead
+ * deprecated `MemcacheSessionHandler`; use `MemcachedSessionHandler` instead
+
+3.3.0
+-----
+
+ * the `Request::setTrustedProxies()` method takes a new `$trustedHeaderSet` argument,
+   see http://symfony.com/doc/current/components/http_foundation/trusting_proxies.html for more info,
+ * deprecated the `Request::setTrustedHeaderName()` and `Request::getTrustedHeaderName()` methods,
+ * added `File\Stream`, to be passed to `BinaryFileResponse` when the size of the served file is unknown,
+   disabling `Range` and `Content-Length` handling, switching to chunked encoding instead
+ * added the `Cookie::fromString()` method that allows to create a cookie from a
+   raw header string
+
+3.1.0
+-----
+
+ * Added support for creating `JsonResponse` with a string of JSON data
+
+3.0.0
+-----
+
+ * The precedence of parameters returned from `Request::get()` changed from "GET, PATH, BODY" to "PATH, GET, BODY"
+
+2.8.0
+-----
+
+ * Finding deep items in `ParameterBag::get()` is deprecated since version 2.8 and
+   will be removed in 3.0.
+
+2.6.0
+-----
+
+ * PdoSessionHandler changes
+   - implemented different session locking strategies to prevent loss of data by concurrent access to the same session
+   - [BC BREAK] save session data in a binary column without base64_encode
+   - [BC BREAK] added lifetime column to the session table which allows to have different lifetimes for each session
+   - implemented lazy connections that are only opened when a session is used by either passing a dsn string
+     explicitly or falling back to session.save_path ini setting
+   - added a createTable method that initializes a correctly defined table depending on the database vendor
+
+2.5.0
+-----
+
+ * added `JsonResponse::setEncodingOptions()` & `JsonResponse::getEncodingOptions()` for easier manipulation
+   of the options used while encoding data to JSON format.
+
+2.4.0
+-----
+
+ * added RequestStack
+ * added Request::getEncodings()
+ * added accessors methods to session handlers
+
+2.3.0
+-----
+
+ * added support for ranges of IPs in trusted proxies
+ * `UploadedFile::isValid` now returns false if the file was not uploaded via HTTP (in a non-test mode)
+ * Improved error-handling of `\Symfony\Component\HttpFoundation\Session\Storage\Handler\PdoSessionHandler`
+   to ensure the supplied PDO handler throws Exceptions on error (as the class expects). Added related test cases
+   to verify that Exceptions are properly thrown when the PDO queries fail.
+
+2.2.0
+-----
+
+ * fixed the Request::create() precedence (URI information always take precedence now)
+ * added Request::getTrustedProxies()
+ * deprecated Request::isProxyTrusted()
+ * [BC BREAK] JsonResponse does not turn a top level empty array to an object anymore, use an ArrayObject to enforce objects
+ * added a IpUtils class to check if an IP belongs to a CIDR
+ * added Request::getRealMethod() to get the "real" HTTP method (getMethod() returns the "intended" HTTP method)
+ * disabled _method request parameter support by default (call Request::enableHttpMethodParameterOverride() to
+   enable it, and Request::getHttpMethodParameterOverride() to check if it is supported)
+ * Request::splitHttpAcceptHeader() method is deprecated and will be removed in 2.3
+ * Deprecated Flashbag::count() and \Countable interface, will be removed in 2.3
+
+2.1.0
+-----
+
+ * added Request::getSchemeAndHttpHost() and Request::getUserInfo()
+ * added a fluent interface to the Response class
+ * added Request::isProxyTrusted()
+ * added JsonResponse
+ * added a getTargetUrl method to RedirectResponse
+ * added support for streamed responses
+ * made Response::prepare() method the place to enforce HTTP specification
+ * [BC BREAK] moved management of the locale from the Session class to the Request class
+ * added a generic access to the PHP built-in filter mechanism: ParameterBag::filter()
+ * made FileBinaryMimeTypeGuesser command configurable
+ * added Request::getUser() and Request::getPassword()
+ * added support for the PATCH method in Request
+ * removed the ContentTypeMimeTypeGuesser class as it is deprecated and never used on PHP 5.3
+ * added ResponseHeaderBag::makeDisposition() (implements RFC 6266)
+ * made mimetype to extension conversion configurable
+ * [BC BREAK] Moved all session related classes and interfaces into own namespace, as
+   `Symfony\Component\HttpFoundation\Session` and renamed classes accordingly.
+   Session handlers are located in the subnamespace `Symfony\Component\HttpFoundation\Session\Handler`.
+ * SessionHandlers must implement `\SessionHandlerInterface` or extend from the
+   `Symfony\Component\HttpFoundation\Storage\Handler\NativeSessionHandler` base class.
+ * Added internal storage driver proxy mechanism for forward compatibility with
+   PHP 5.4 `\SessionHandler` class.
+ * Added session handlers for custom Memcache, Memcached and Null session save handlers.
+ * [BC BREAK] Removed `NativeSessionStorage` and replaced with `NativeFileSessionHandler`.
+ * [BC BREAK] `SessionStorageInterface` methods removed: `write()`, `read()` and
+   `remove()`.  Added `getBag()`, `registerBag()`.  The `NativeSessionStorage` class
+   is a mediator for the session storage internals including the session handlers
+   which do the real work of participating in the internal PHP session workflow.
+ * [BC BREAK] Introduced mock implementations of `SessionStorage` to enable unit
+   and functional testing without starting real PHP sessions.  Removed
+   `ArraySessionStorage`, and replaced with `MockArraySessionStorage` for unit
+   tests; removed `FilesystemSessionStorage`, and replaced with`MockFileSessionStorage`
+   for functional tests.  These do not interact with global session ini
+   configuration values, session functions or `$_SESSION` superglobal. This means
+   they can be configured directly allowing multiple instances to work without
+   conflicting in the same PHP process.
+ * [BC BREAK] Removed the `close()` method from the `Session` class, as this is
+   now redundant.
+ * Deprecated the following methods from the Session class: `setFlash()`, `setFlashes()`
+   `getFlash()`, `hasFlash()`, and `removeFlash()`. Use `getFlashBag()` instead
+   which returns a `FlashBagInterface`.
+ * `Session->clear()` now only clears session attributes as before it cleared
+   flash messages and attributes. `Session->getFlashBag()->all()` clears flashes now.
+ * Session data is now managed by `SessionBagInterface` to better encapsulate
+   session data.
+ * Refactored session attribute and flash messages system to their own
+  `SessionBagInterface` implementations.
+ * Added `FlashBag`. Flashes expire when retrieved by `get()` or `all()`. This
+   implementation is ESI compatible.
+ * Added `AutoExpireFlashBag` (default) to replicate Symfony 2.0.x auto expire
+   behaviour of messages auto expiring after one page page load.  Messages must
+   be retrieved by `get()` or `all()`.
+ * Added `Symfony\Component\HttpFoundation\Attribute\AttributeBag` to replicate
+   attributes storage behaviour from 2.0.x (default).
+ * Added `Symfony\Component\HttpFoundation\Attribute\NamespacedAttributeBag` for
+   namespace session attributes.
+ * Flash API can stores messages in an array so there may be multiple messages
+   per flash type.  The old `Session` class API remains without BC break as it
+   will allow single messages as before.
+ * Added basic session meta-data to the session to record session create time,
+   last updated time, and the lifetime of the session cookie that was provided
+   to the client.
+ * Request::getClientIp() method doesn't take a parameter anymore but bases
+   itself on the trustProxy parameter.
+ * Added isMethod() to Request object.
+ * [BC BREAK] The methods `getPathInfo()`, `getBaseUrl()` and `getBasePath()` of
+   a `Request` now all return a raw value (vs a urldecoded value before). Any call
+   to one of these methods must be checked and wrapped in a `rawurldecode()` if
+   needed.

+ * for the same session will wait until the other one finished writing. For this
+ * reason it's best practice to close a session as early as possible to improve
+ * concurrency. PHPs internal files session handler also implements locking.

+ * Attention: Since SQLite does not support row level locks but locks the whole database,
+ * it means only one session can be accessed at a time. Even different sessions would wait
+ * for another to finish. So saving session in SQLite should only be considered for
+ * development or prototypes.
+ *
+ * Session data is a binary string that can contain non-printable characters like the null byte.
+ * For this reason it must be saved in a binary column in the database like BLOB in MySQL.
+ * Saving it in a character column could corrupt the data. You can use createTable()

+Symfony Polyfill / Php70
+========================
+
+This component provides features unavailable in releases prior to PHP 7.0:
+
+- [`intdiv`](http://php.net/intdiv)
+- [`preg_replace_callback_array`](http://php.net/preg_replace_callback_array)
+- [`error_clear_last`](http://php.net/error_clear_last)
+- `random_bytes` and `random_int` (from [paragonie/random_compat](https://github.com/paragonie/random_compat))
+- [`*Error` throwable classes](http://php.net/Error)
+- [`PHP_INT_MIN`](http://php.net/manual/en/reserved.constants.php#constant.php-int-min)
+- `SessionUpdateTimestampHandlerInterface`
+
+More information can be found in the
+[main Polyfill README](https://github.com/symfony/polyfill/blob/master/README.md).
+
+Compatibility notes
+===================
+
+To write portable code between PHP5 and PHP7, some care must be taken:
+- `\*Error` exceptions must be caught before `\Exception`;
+- after calling `error_clear_last()`, the result of `$e = error_get_last()` must be
+  verified using `isset($e['message'][0])` instead of `null !== $e`.
+

+CHANGELOG
+=========
+
+3.4.0
+-----
+
+ * Added `NoConfigurationException`.
+ * Added the possibility to define a prefix for all routes of a controller via @Route(name="prefix_")
+ * Added support for prioritized routing loaders.
+ * Add matched and default parameters to redirect responses
+ * Added support for a `controller` keyword for configuring route controllers in YAML and XML configurations.
+
+3.3.0
+-----
+
+  * [DEPRECATION] Class parameters have been deprecated and will be removed in 4.0.
+    * router.options.generator_class
+    * router.options.generator_base_class
+    * router.options.generator_dumper_class
+    * router.options.matcher_class
+    * router.options.matcher_base_class
+    * router.options.matcher_dumper_class
+    * router.options.matcher.cache_class
+    * router.options.generator.cache_class
+
+3.2.0
+-----
+
+ * Added support for `bool`, `int`, `float`, `string`, `list` and `map` defaults in XML configurations.
+ * Added support for UTF-8 requirements
+
+2.8.0
+-----
+
+ * allowed specifying a directory to recursively load all routing configuration files it contains
+ * Added ObjectRouteLoader and ServiceRouteLoader that allow routes to be loaded
+   by calling a method on an object/service.
+ * [DEPRECATION] Deprecated the hardcoded value for the `$referenceType` argument of the `UrlGeneratorInterface::generate` method.
+   Use the constants defined in the `UrlGeneratorInterface` instead.
+
+   Before:
+
+   ```php
+   $router->generate('blog_show', array('slug' => 'my-blog-post'), true);
+   ```
+
+   After:
+
+   ```php
+   use Symfony\Component\Routing\Generator\UrlGeneratorInterface;
+
+   $router->generate('blog_show', array('slug' => 'my-blog-post'), UrlGeneratorInterface::ABSOLUTE_URL);
+   ```
+
+2.5.0
+-----
+
+ * [DEPRECATION] The `ApacheMatcherDumper` and `ApacheUrlMatcher` were deprecated and
+   will be removed in Symfony 3.0, since the performance gains were minimal and
+   it's hard to replicate the behaviour of PHP implementation.
+
+2.3.0
+-----
+
+ * added RequestContext::getQueryString()
+
+2.2.0
+-----
+
+ * [DEPRECATION] Several route settings have been renamed (the old ones will be removed in 3.0):
+
+    * The `pattern` setting for a route has been deprecated in favor of `path`
+    * The `_scheme` and `_method` requirements have been moved to the `schemes` and `methods` settings
+
+   Before:
+
+   ```yaml
+   article_edit:
+       pattern: /article/{id}
+       requirements: { '_method': 'POST|PUT', '_scheme': 'https', 'id': '\d+' }
+   ```
+
+   ```xml
+   <route id="article_edit" pattern="/article/{id}">
+       <requirement key="_method">POST|PUT</requirement>
+       <requirement key="_scheme">https</requirement>
+       <requirement key="id">\d+</requirement>
+   </route>
+   ```
+
+   ```php
+   $route = new Route();
+   $route->setPattern('/article/{id}');
+   $route->setRequirement('_method', 'POST|PUT');
+   $route->setRequirement('_scheme', 'https');
+   ```
+
+   After:
+
+   ```yaml
+   article_edit:
+       path: /article/{id}
+       methods: [POST, PUT]
+       schemes: https
+       requirements: { 'id': '\d+' }
+   ```
+
+   ```xml
+   <route id="article_edit" pattern="/article/{id}" methods="POST PUT" schemes="https">
+       <requirement key="id">\d+</requirement>
+   </route>
+   ```
+
+   ```php
+   $route = new Route();
+   $route->setPath('/article/{id}');
+   $route->setMethods(array('POST', 'PUT'));
+   $route->setSchemes('https');
+   ```
+
+ * [BC BREAK] RouteCollection does not behave like a tree structure anymore but as
+   a flat array of Routes. So when using PHP to build the RouteCollection, you must
+   make sure to add routes to the sub-collection before adding it to the parent
+   collection (this is not relevant when using YAML or XML for Route definitions).
+
+   Before:
+
+   ```php
+   $rootCollection = new RouteCollection();
+   $subCollection = new RouteCollection();
+   $rootCollection->addCollection($subCollection);
+   $subCollection->add('foo', new Route('/foo'));
+   ```
+
+   After:
+
+   ```php
+   $rootCollection = new RouteCollection();
+   $subCollection = new RouteCollection();
+   $subCollection->add('foo', new Route('/foo'));
+   $rootCollection->addCollection($subCollection);
+   ```
+
+   Also one must call `addCollection` from the bottom to the top hierarchy.
+   So the correct sequence is the following (and not the reverse):
+
+   ```php
+   $childCollection->addCollection($grandchildCollection);
+   $rootCollection->addCollection($childCollection);
+   ```
+
+ * [DEPRECATION] The methods `RouteCollection::getParent()` and `RouteCollection::getRoot()`
+   have been deprecated and will be removed in Symfony 2.3.
+ * [BC BREAK] Misusing the `RouteCollection::addPrefix` method to add defaults, requirements
+   or options without adding a prefix is not supported anymore. So if you called `addPrefix`
+   with an empty prefix or `/` only (both have no relevance), like
+   `addPrefix('', $defaultsArray, $requirementsArray, $optionsArray)`
+   you need to use the new dedicated methods `addDefaults($defaultsArray)`,
+   `addRequirements($requirementsArray)` or `addOptions($optionsArray)` instead.
+ * [DEPRECATION] The `$options` parameter to `RouteCollection::addPrefix()` has been deprecated
+   because adding options has nothing to do with adding a path prefix. If you want to add options
+   to all child routes of a RouteCollection, you can use `addOptions()`.
+ * [DEPRECATION] The method `RouteCollection::getPrefix()` has been deprecated
+   because it suggested that all routes in the collection would have this prefix, which is
+   not necessarily true. On top of that, since there is no tree structure anymore, this method
+   is also useless. Don't worry about performance, prefix optimization for matching is still done
+   in the dumper, which was also improved in 2.2.0 to find even more grouping possibilities.
+ * [DEPRECATION] `RouteCollection::addCollection(RouteCollection $collection)` should now only be
+   used with a single parameter. The other params `$prefix`, `$default`, `$requirements` and `$options`
+   will still work, but have been deprecated. The `addPrefix` method should be used for this
+   use-case instead.
+   Before: `$parentCollection->addCollection($collection, '/prefix', array(...), array(...))`
+   After:
+   ```php
+   $collection->addPrefix('/prefix', array(...), array(...));
+   $parentCollection->addCollection($collection);
+   ```
+ * added support for the method default argument values when defining a @Route
+ * Adjacent placeholders without separator work now, e.g. `/{x}{y}{z}.{_format}`.
+ * Characters that function as separator between placeholders are now whitelisted
+   to fix routes with normal text around a variable, e.g. `/prefix{var}suffix`.
+ * [BC BREAK] The default requirement of a variable has been changed slightly.
+   Previously it disallowed the previous and the next char around a variable. Now
+   it disallows the slash (`/`) and the next char. Using the previous char added
+   no value and was problematic because the route `/index.{_format}` would be
+   matched by `/index.ht/ml`.
+ * The default requirement now uses possessive quantifiers when possible which
+   improves matching performance by up to 20% because it prevents backtracking
+   when it's not needed.
+ * The ConfigurableRequirementsInterface can now also be used to disable the requirements
+   check on URL generation completely by calling `setStrictRequirements(null)`. It
+   improves performance in production environment as you should know that params always
+   pass the requirements (otherwise it would break your link anyway).
+ * There is no restriction on the route name anymore. So non-alphanumeric characters
+   are now also allowed.
+ * [BC BREAK] `RouteCompilerInterface::compile(Route $route)` was made static
+   (only relevant if you implemented your own RouteCompiler).
+ * Added possibility to generate relative paths and network paths in the UrlGenerator, e.g.
+   "../parent-file" and "//example.com/dir/file". The third parameter in
+   `UrlGeneratorInterface::generate($name, $parameters = array(), $referenceType = self::ABSOLUTE_PATH)`
+   now accepts more values and you should use the constants defined in `UrlGeneratorInterface` for
+   claritiy. The old method calls with a Boolean parameter will continue to work because they
+   equal the signature using the constants.
+
+2.1.0
+-----
+
+ * added RequestMatcherInterface
+ * added RequestContext::fromRequest()
+ * the UrlMatcher does not throw a \LogicException anymore when the required
+   scheme is not the current one
+ * added TraceableUrlMatcher
+ * added the possibility to define options, default values and requirements
+   for placeholders in prefix, including imported routes
+ * added RouterInterface::getRouteCollection
+ * [BC BREAK] the UrlMatcher urldecodes the route parameters only once, they
+   were decoded twice before. Note that the `urldecode()` calls have been
+   changed for a single `rawurldecode()` in order to support `+` for input
+   paths.
+ * added RouteCollection::getRoot method to retrieve the root of a
+   RouteCollection tree
+ * [BC BREAK] made RouteCollection::setParent private which could not have
+   been used anyway without creating inconsistencies
+ * [BC BREAK] RouteCollection::remove also removes a route from parent
+   collections (not only from its children)
+ * added ConfigurableRequirementsInterface that allows to disable exceptions
+   (and generate empty URLs instead) when generating a route with an invalid
+   parameter value

+ *   production environment. It should log the mismatch so one can review it.
+ * - setStrictRequirements(null): Return the URL with the given parameters without
+ *   checking the requirements at all. When generating a URL you should either trust
+ *   your params or you validated them beforehand because otherwise it would break your
+ *   link anyway. So in production environment you should know that params always pass

+ * You need to define an implementation for the getRouteDefaults() method. Most of the

+ * (a controller in MVC speak).
+ *
+ * The @Route annotation can be set on the class (for global parameters),
+ * and on each method.
+ *
+ * The @Route annotation main value is the route path. The annotation also
+ * recognizes several parameters: requirements, options, defaults, schemes,
+ * methods, host, and name. The name parameter is mandatory.

+ *     class Blog
