     *  - The same regexp can be used several times when the logic in the switch rejects the match. When this happens, the

 * ConfigurableRequirementsInterface must be implemented by URL generators that

 *
 * The possible configurations and use-cases:
 * - setStrictRequirements(true): Throw an exception for mismatching requirements. This
 *   is mostly useful in development environment.
 * - setStrictRequirements(false): Don't throw an exception but return an empty string as URL for
 *   mismatching requirements and log the problem. Useful when you cannot control all
 *   params because they come from third party libs but don't want to have a 404 in
 *   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
 *   the requirements. Thus this option allows to disable the check on URL generation for
 *   performance reasons (saving a preg_match for each requirement every time a URL is
 *   generated).

/**
 * AnnotationClassLoader loads routing information from a PHP class and its methods.
 *
 * You need to define an implementation for the configureRoute() method. Most of the
 * time, this method should define some PHP callable to be called for the route
 * (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.
 * Here is an example of how you should be able to use it:
 *     /**
 *      * @Route("/Blog")
 *      * /
 *     class Blog
 *     {
 *         /**
 *          * @Route("/", name="blog_index")
 *          * /
 *         public function index()
 *         {
 *         }
 *         /**
 *          * @Route("/{id}", name="blog_post", requirements = {"id" = "\d+"})
 *          * /
 *         public function show()
 *         {
 *         }
 *     }
 *
 * On PHP 8, the annotation class can be used as an attribute as well:
 *     #[Route('/Blog')]
 *     class Blog
 *     {
 *         #[Route('/', name: 'blog_index')]
 *         public function index()
 *         {
 *         }
 *         #[Route('/{id}', name: 'blog_post', requirements: ["id" => '\d+'])]
 *         public function show()
 *         {
 *         }
 *     }

 * [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', ['slug' => 'my-blog-post'], true);
   ```

After:

```php
   use Symfony\Component\Routing\Generator\UrlGeneratorInterface;

$router->generate('blog_show', ['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 behavior 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(['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', [...], [...])`
   After:
   ```php
   $collection->addPrefix('/prefix', [...], [...]);
   $parentCollection->addCollection($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 = [], $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

=================

The Routing component maps an HTTP request to a set of configuration variables.

Getting Started
---------------

```
$ composer require symfony/routing
```

```php
use App\Controller\BlogController;
use Symfony\Component\Routing\Generator\UrlGenerator;
use Symfony\Component\Routing\Matcher\UrlMatcher;
use Symfony\Component\Routing\RequestContext;
use Symfony\Component\Routing\Route;
use Symfony\Component\Routing\RouteCollection;

$route = new Route('/blog/{slug}', ['_controller' => BlogController::class]);
$routes = new RouteCollection();
$routes->add('blog_show', $route);

$context = new RequestContext();

// Routing can match routes with incoming requests
$matcher = new UrlMatcher($routes, $context);
$parameters = $matcher->match('/blog/lorem-ipsum');
// $parameters = [
//     '_controller' => 'App\Controller\BlogController',
//     'slug' => 'lorem-ipsum',
//     '_route' => 'blog_show'
// ]

// Routing can also generate URLs for a given route
$generator = new UrlGenerator($routes, $context);
$url = $generator->generate('blog_show', [
    'slug' => 'my-blog-post',
]);
// $url = '/blog/my-blog-post'
```

     *  * data_field: The field name for storing the session data [default: data]
     *  * time_field: The field name for storing the timestamp [default: time]
     *  * expiry_field: The field name for storing the expiry-timestamp [default: expires_at].
     *
     * It is strongly recommended to put an index on the `expiry_field` for
     * garbage-collection. Alternatively it's possible to automatically expire
     * the sessions in the database as described below:
     *
     * A TTL collections can be used on MongoDB 2.2+ to cleanup expired sessions
     * automatically. Such an index can for example look like this:
     *
     *     db.<session-collection>.createIndex(
     *         { "<expiry-field>": 1 },
     *         { "expireAfterSeconds": 0 }
     *     )
     *
     * More details on: https://docs.mongodb.org/manual/tutorial/expire-data/
     *
     * If you use such an index, you can drop `gc_probability` to 0 since
     * no garbage-collection is required.

/**
 * Session handler using a PDO connection to read and write data.
 *
 * It works with MySQL, PostgreSQL, Oracle, SQL Server and SQLite and implements
 * different locking strategies to handle concurrent access to the same session.
 * Locking is necessary to prevent loss of data due to race conditions and to keep
 * the session data consistent between read() and write(). With locking, requests
 * 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()
 * to initialize a correctly defined table.

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
   behavior 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 behavior 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.

=============================

A generic function and convention to trigger deprecation notices.

This package provides a single global function named `trigger_deprecation()` that triggers silenced deprecation notices.

By using a custom PHP error handler such as the one provided by the Symfony ErrorHandler component,
the triggered deprecations can be caught and logged for later discovery, both on dev and prod environments.

The function requires at least 3 arguments:
 - the name of the Composer package that is triggering the deprecation
 - the version of the package that introduced the deprecation
 - the message of the deprecation
 - more arguments can be provided: they will be inserted in the message using `printf()` formatting

Example:
```php
trigger_deprecation('symfony/blockchain', '8.9', 'Using "%s" is deprecated, use "%s" instead.', 'bitcoin', 'fabcoin');
```

This will generate the following message:
`Since symfony/blockchain 8.9: Using "bitcoin" is deprecated, use "fabcoin" instead.`

While not necessarily recommended, the deprecation notices can be completely ignored by declaring an empty
`function trigger_deprecation() {}` in your application.

All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/)
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## Unreleased

## 2.1.0 - 2021-10-06

### Changed

- Attempting to create a `Uri` object from a malformed URI will no longer throw a generic
  `InvalidArgumentException`, but rather a `MalformedUriException`, which inherits from the former
  for backwards compatibility. Callers relying on the exception being thrown to detect invalid
  URIs should catch the new exception.

### Fixed

- Return `null` in caching stream size if remote size is `null`

## 2.0.0 - 2021-06-30

Identical to the RC release.

## 2.0.0@RC-1 - 2021-04-29

### Fixed

- Handle possibly unset `url` in `stream_get_meta_data`

## 2.0.0@beta-1 - 2021-03-21

### Added

- Rriggering of silenced deprecation warnings.

### Fixed

- Reverted BC break by reintroducing behavior to automagically fix a URI with a

## [1.4.0] - 2017-02-21

### Added

- Added common URI utility methods based on RFC 3986 (see documentation in the readme):
  - `Uri::isDefaultPort`

  Invalid modifications will throw an exception instead of returning a wrong URI or
  doing some magic.
  - `(new Uri)->withPath('foo')->withHost('example.com')` will throw an exception
    because the path of a URI with an authority must start with a slash "/" or be empty
  - `(new Uri())->withScheme('http')` will return `'http://localhost'`

### Deprecated

- `Uri::resolve` in favor of `UriResolver::resolve`
- `Uri::removeDotSegments` in favor of `UriResolver::removeDotSegments`

### Fixed

- `Stream::read` when length parameter <= 0.
- `copy_to_stream` reads bytes in chunks instead of `maxLen` into memory.
- `ServerRequest::getUriFromGlobals` when `Host` header contains port.
- Compatibility of URIs with `file` scheme and empty host.

## [1.3.1] - 2016-06-25

### Fixed

- `Uri::__toString` for network path references, e.g. `//example.org`.
- Missing lowercase normalization for host.
- Handling of URI components in case they are `'0'` in a lot of places,
  e.g. as a user info password.
- `Uri::withAddedHeader` to correctly merge headers with different case.
- Trimming of header values in `Uri::withAddedHeader`. Header values may
  be surrounded by whitespace which should be ignored according to RFC 7230
  Section 3.2.4. This does not apply to header names.
- `Uri::withAddedHeader` with an array of header values.
- `Uri::resolve` when base path has no slash and handling of fragment.
- Handling of encoding in `Uri::with(out)QueryValue` so one can pass the
  key/value both in encoded as well as decoded form to those methods. This is
  consistent with withPath, withQuery etc.
- `ServerRequest::withoutAttribute` when attribute value is null.

## [1.3.0] - 2016-04-13

### Added

- Remaining interfaces needed for full PSR7 compatibility
  (ServerRequestInterface, UploadedFileInterface, etc.).
- Support for stream_for from scalars.

### Changed

- Can now extend Uri.

### Fixed
- A bug in validating request methods by making it more permissive.

## [1.2.3] - 2016-02-18

### Fixed

- Support in `GuzzleHttp\Psr7\CachingStream` for seeking forward on remote
  streams, which can sometimes return fewer bytes than requested with `fread`.
- Handling of gzipped responses with FNAME headers.

## [1.2.2] - 2016-01-22

### Added

- Support for URIs without any authority.
- Support for HTTP 451 'Unavailable For Legal Reasons.'
- Support for using '0' as a filename.
- Support for including non-standard ports in Host headers.

## [1.2.1] - 2015-11-02

### Changes

- Now supporting negative offsets when seeking to SEEK_END.

## [1.2.0] - 2015-08-15

### Changed

- Body as `"0"` is now properly added to a response.
- Now allowing forward seeking in CachingStream.
- Now properly parsing HTTP requests that contain proxy targets in
  `parse_request`.
- functions.php is now conditionally required.
- user-info is no longer dropped when resolving URIs.

## [1.1.0] - 2015-06-24

### Changed

- URIs can now be relative.
- `multipart/form-data` headers are now overridden case-insensitively.
- URI paths no longer encode the following characters because they are allowed
  in URIs: "(", ")", "*", "!", "'"
- A port is no longer added to a URI when the scheme is missing and no port is
  present.

# 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\Utils::streamFor('abc, ');
$b = Psr7\Utils::streamFor('123.');
$composed = new Psr7\AppendStream([$a, $b]);

$composed->addStream(Psr7\Utils::streamFor(' 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\Utils::streamFor(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\Utils::streamFor();

// 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\Utils::streamFor('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 zlib (HTTP deflate, RFC1950) or gzipped (RFC1952) content.

This stream decorator 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\Utils::streamFor(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\Utils::streamFor('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\Utils::streamFor('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\Utils::streamFor('hello!');
$resource = StreamWrapper::getResource($stream);
echo fread($resource, 6); // outputs hello!
```

# Static API

There are various static methods available under the `GuzzleHttp\Psr7` namespace.

## `GuzzleHttp\Psr7\Message::toString`

`public static function toString(MessageInterface $message): string`

Returns the string representation of an HTTP message.

```php
$request = new GuzzleHttp\Psr7\Request('GET', 'http://example.com');
echo GuzzleHttp\Psr7\Message::toString($request);
```

## `GuzzleHttp\Psr7\Message::bodySummary`

`public static function bodySummary(MessageInterface $message, int $truncateAt = 120): string|null`

Get a short summary of the message body.

Will return `null` if the response is not printable.

## `GuzzleHttp\Psr7\Message::rewindBody`

`public static function rewindBody(MessageInterface $message): void`

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`.

## `GuzzleHttp\Psr7\Message::parseMessage`

`public static function parseMessage(string $message): array`

Parses an HTTP message into an associative array.

The array contains the "start-line" key containing the start line of
the message, "headers" key containing an associative array of header
array values, and a "body" key containing the body of the message.

## `GuzzleHttp\Psr7\Message::parseRequestUri`

`public static function parseRequestUri(string $path, array $headers): string`

Constructs a URI for an HTTP request message.

## `GuzzleHttp\Psr7\Message::parseRequest`

`public static function parseRequest(string $message): Request`

Parses a request message string into a request object.

## `GuzzleHttp\Psr7\Message::parseResponse`

`public static function parseResponse(string $message): Response`

Parses a response message string into a response object.

## `GuzzleHttp\Psr7\Header::parse`

`public static function parse(string|array $header): array`

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.

## `GuzzleHttp\Psr7\Header::normalize`

`public static function normalize(string|array $header): array`

Converts an array of header values that may contain comma separated
headers into an array of headers with no comma separated values.

## `GuzzleHttp\Psr7\Query::parse`

`public static function parse(string $str, int|bool $urlEncoding = true): array`

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'])`.

## `GuzzleHttp\Psr7\Query::build`

`public static function build(array $params, int|false $encoding = PHP_QUERY_RFC3986): string`

Build a query string from an array of key value pairs.

This function can use the return value of `parse()` to build a query
string. This function does not modify the provided keys when an array is
encountered (like `http_build_query()` would).

## `GuzzleHttp\Psr7\Utils::caselessRemove`

`public static function caselessRemove(iterable<string> $keys, $keys, array $data): array`

Remove the items given by the keys, case insensitively from the data.

## `GuzzleHttp\Psr7\Utils::copyToStream`

`public static function copyToStream(StreamInterface $source, StreamInterface $dest, int $maxLen = -1): void`

Copy the contents of a stream into another stream until the given number
of bytes have been read.

## `GuzzleHttp\Psr7\Utils::copyToString`

`public static function copyToString(StreamInterface $stream, int $maxLen = -1): string`

Copy the contents of a stream into a string until the given number of
bytes have been read.

## `GuzzleHttp\Psr7\Utils::hash`

`public static function hash(StreamInterface $stream, string $algo, bool $rawOutput = false): string`

Calculate a hash of a stream.

This method reads the entire stream to calculate a rolling hash, based on
PHP's `hash_init` functions.

## `GuzzleHttp\Psr7\Utils::modifyRequest`

`public static function modifyRequest(RequestInterface $request, array $changes): RequestInterface`

Clone and modify a request with the given changes.

This method is useful for reducing the number of clones needed to mutate
a message.

- 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.

## `GuzzleHttp\Psr7\Utils::readLine`

`public static function readLine(StreamInterface $stream, int $maxLength = null): string`

Read a line from the stream up to the maximum allowed buffer length.

## `GuzzleHttp\Psr7\Utils::streamFor`

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\Utils::streamFor('foo');
$stream = GuzzleHttp\Psr7\Utils::streamFor(fopen('/path/to/file', 'r'));

$generator = function ($bytes) {
    for ($i = 0; $i < $bytes; $i++) {
        yield ' ';
    }
}

$stream = GuzzleHttp\Psr7\Utils::streamFor($generator(100));
```

## `GuzzleHttp\Psr7\Utils::tryFopen`

`public static function tryFopen(string $filename, string $mode): resource`

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.

## `GuzzleHttp\Psr7\Utils::uriFor`

`public static function uriFor(string|UriInterface $uri): UriInterface`

Returns a UriInterface for the given value.

This function accepts a string or UriInterface and returns a
UriInterface for the given value. If the value is already a
UriInterface, it is returned as-is.

## `GuzzleHttp\Psr7\MimeType::fromFilename`

`public static function fromFilename(string $filename): string|null`

Determines the mimetype of a file by looking at its extension.

## `GuzzleHttp\Psr7\MimeType::fromExtension`

`public static function fromExtension(string $extension): string|null`

Maps a file extensions to a mimetype.

## Upgrading from Function API

# Additional URI Methods

Aside from the standard `Psr\Http\Message\UriInterface` implementation in form of the `GuzzleHttp\Psr7\Uri` class,
this library also provides additional functionality when working with URIs as static methods.

## URI Types

An instance of `Psr\Http\Message\UriInterface` can either be an absolute URI or a relative reference.
An absolute URI has a scheme. A relative reference is used to express a URI relative to another URI,
the base URI. Relative references can be divided into several forms according to
[RFC 3986 Section 4.2](https://tools.ietf.org/html/rfc3986#section-4.2):

- network-path references, e.g. `//example.com/path`
- absolute-path references, e.g. `/path`
- relative-path references, e.g. `subpath`

The following methods can be used to identify the type of the URI.

### `GuzzleHttp\Psr7\Uri::isAbsolute`

`public static function isAbsolute(UriInterface $uri): bool`

Whether the URI is absolute, i.e. it has a scheme.

### `GuzzleHttp\Psr7\Uri::isNetworkPathReference`

`public static function isNetworkPathReference(UriInterface $uri): bool`

Whether the URI is a network-path reference. A relative reference that begins with two slash characters is
termed an network-path reference.

### `GuzzleHttp\Psr7\Uri::isAbsolutePathReference`

`public static function isAbsolutePathReference(UriInterface $uri): bool`

Whether the URI is a absolute-path reference. A relative reference that begins with a single slash character is
termed an absolute-path reference.

### `GuzzleHttp\Psr7\Uri::isRelativePathReference`

`public static function isRelativePathReference(UriInterface $uri): bool`

Whether the URI is a relative-path reference. A relative reference that does not begin with a slash character is
termed a relative-path reference.

### `GuzzleHttp\Psr7\Uri::isSameDocumentReference`

`public static function isSameDocumentReference(UriInterface $uri, UriInterface $base = null): bool`

Whether the URI is a same-document reference. A same-document reference refers to a URI that is, aside from its
fragment component, identical to the base URI. When no base URI is given, only an empty URI reference
(apart from its fragment) is considered a same-document reference.

## URI Components

Additional methods to work with URI components.

### `GuzzleHttp\Psr7\Uri::isDefaultPort`

`public static function isDefaultPort(UriInterface $uri): bool`

Whether the URI has the default port of the current scheme. `Psr\Http\Message\UriInterface::getPort` may return null
or the standard port. This method can be used independently of the implementation.

### `GuzzleHttp\Psr7\Uri::composeComponents`

`public static function composeComponents($scheme, $authority, $path, $query, $fragment): string`

Composes a URI reference string from its various components according to
[RFC 3986 Section 5.3](https://tools.ietf.org/html/rfc3986#section-5.3). Usually this method does not need to be called
manually but instead is used indirectly via `Psr\Http\Message\UriInterface::__toString`.

### `GuzzleHttp\Psr7\Uri::fromParts`

`public static function fromParts(array $parts): UriInterface`

Creates a URI from a hash of [`parse_url`](http://php.net/manual/en/function.parse-url.php) components.

### `GuzzleHttp\Psr7\Uri::withQueryValue`

`public static function withQueryValue(UriInterface $uri, $key, $value): UriInterface`

Creates a new URI with a specific query string value. Any existing query string values that exactly match the
provided key are removed and replaced with the given key value pair. A value of null will set the query string
key without a value, e.g. "key" instead of "key=value".

### `GuzzleHttp\Psr7\Uri::withQueryValues`

`public static function withQueryValues(UriInterface $uri, array $keyValueArray): UriInterface`

Creates a new URI with multiple query string values. It has the same behavior as `withQueryValue()` but for an
associative array of key => value.

### `GuzzleHttp\Psr7\Uri::withoutQueryValue`

`public static function withoutQueryValue(UriInterface $uri, $key): UriInterface`

Creates a new URI with a specific query string value removed. Any existing query string values that exactly match the
provided key are removed.

## Reference Resolution

`GuzzleHttp\Psr7\UriResolver` provides methods to resolve a URI reference in the context of a base URI according
to [RFC 3986 Section 5](https://tools.ietf.org/html/rfc3986#section-5). This is for example also what web browsers
do when resolving a link in a website based on the current request URI.

### `GuzzleHttp\Psr7\UriResolver::resolve`

`public static function resolve(UriInterface $base, UriInterface $rel): UriInterface`

Converts the relative URI into a new URI that is resolved against the base URI.

### `GuzzleHttp\Psr7\UriResolver::removeDotSegments`

`public static function removeDotSegments(string $path): string`

Removes dot segments from a path and returns the new path according to
[RFC 3986 Section 5.2.4](https://tools.ietf.org/html/rfc3986#section-5.2.4).

### `GuzzleHttp\Psr7\UriResolver::relativize`

`public static function relativize(UriInterface $base, UriInterface $target): UriInterface`

Returns the target URI as a relative reference from the base URI. This method is the counterpart to resolve():

```php
(string) $target === (string) UriResolver::resolve($base, UriResolver::relativize($base, $target))
```

One use-case is to use the current request URI as base URI and then generate relative links in your documents
to reduce the document size or offer self-contained downloadable document archives.

```php
$base = new Uri('http://example.com/a/b/');
echo UriResolver::relativize($base, new Uri('http://example.com/a/b/c'));  // prints 'c'.
echo UriResolver::relativize($base, new Uri('http://example.com/a/x/y'));  // prints '../x/y'.
echo UriResolver::relativize($base, new Uri('http://example.com/a/b/?q')); // prints '?q'.
echo UriResolver::relativize($base, new Uri('http://example.org/a/b/'));   // prints '//example.org/a/b/'.
```

## Normalization and Comparison

`GuzzleHttp\Psr7\UriNormalizer` provides methods to normalize and compare URIs according to
[RFC 3986 Section 6](https://tools.ietf.org/html/rfc3986#section-6).

### `GuzzleHttp\Psr7\UriNormalizer::normalize`

`public static function normalize(UriInterface $uri, $flags = self::PRESERVING_NORMALIZATIONS): UriInterface`

Returns a normalized URI. The scheme and host component are already normalized to lowercase per PSR-7 UriInterface.
This methods adds additional normalizations that can be configured with the `$flags` parameter which is a bitmask
of normalizations to apply. The following normalizations are available:

- `UriNormalizer::PRESERVING_NORMALIZATIONS`

Default normalizations which only include the ones that preserve semantics.

- `UriNormalizer::CAPITALIZE_PERCENT_ENCODING`

All letters within a percent-encoding triplet (e.g., "%3A") are case-insensitive, and should be capitalized.

Example: `http://example.org/a%c2%b1b` → `http://example.org/a%C2%B1b`

- `UriNormalizer::DECODE_UNRESERVED_CHARACTERS`

Decodes percent-encoded octets of unreserved characters. For consistency, percent-encoded octets in the ranges of
    ALPHA (%41–%5A and %61–%7A), DIGIT (%30–%39), hyphen (%2D), period (%2E), underscore (%5F), or tilde (%7E) should
    not be created by URI producers and, when found in a URI, should be decoded to their corresponding unreserved
    characters by URI normalizers.

Example: `http://example.org/%7Eusern%61me/` → `http://example.org/~username/`

- `UriNormalizer::CONVERT_EMPTY_PATH`

Converts the empty path to "/" for http and https URIs.

Example: `http://example.org` → `http://example.org/`

- `UriNormalizer::REMOVE_DEFAULT_HOST`

Removes the default host of the given URI scheme from the URI. Only the "file" scheme defines the default host
    "localhost". All of `file:/myfile`, `file:///myfile`, and `file://localhost/myfile` are equivalent according to
    RFC 3986.

Example: `file://localhost/myfile` → `file:///myfile`

- `UriNormalizer::REMOVE_DEFAULT_PORT`

Removes the default port of the given URI scheme from the URI.

Example: `http://example.org:80/` → `http://example.org/`

- `UriNormalizer::REMOVE_DOT_SEGMENTS`

Removes unnecessary dot-segments. Dot-segments in relative-path references are not removed as it would
    change the semantics of the URI reference.

Example: `http://example.org/../a/b/../c/./d.html` → `http://example.org/a/c/d.html`

- `UriNormalizer::REMOVE_DUPLICATE_SLASHES`

Paths which include two or more adjacent slashes are converted to one. Webservers usually ignore duplicate slashes
    and treat those URIs equivalent. But in theory those URIs do not need to be equivalent. So this normalization
    may change the semantics. Encoded slashes (%2F) are not removed.

Example: `http://example.org//foo///bar.html` → `http://example.org/foo/bar.html`

- `UriNormalizer::SORT_QUERY_PARAMETERS`

Sort query parameters with their values in alphabetical order. However, the order of parameters in a URI may be
    significant (this is not defined by the standard). So this normalization is not safe and may change the semantics
    of the URI.

Example: `?lang=en&article=fred` → `?article=fred&lang=en`

### `GuzzleHttp\Psr7\UriNormalizer::isEquivalent`

`public static function isEquivalent(UriInterface $uri1, UriInterface $uri2, $normalizations = self::PRESERVING_NORMALIZATIONS): bool`

Whether two URIs can be considered equivalent. Both URIs are normalized automatically before comparison with the given
`$normalizations` bitmask. The method also accepts relative URI references and returns true when they are equivalent.
This of course assumes they will be resolved against the same base URI. If this is not the case, determination of
equivalence or difference of relative references does not mean anything.

PK������h�\^�K�3��3�� ��vendor/ratchet/rfc6455/README.mdnu��Iw����������# RFC6455 - The WebSocket Protocol

[![Build Status](https://github.com/ratchetphp/RFC6455/workflows/CI/badge.svg)](https://github.com/ratchetphp/RFC6455/actions)
[![Autobahn Testsuite](https://img.shields.io/badge/Autobahn-passing-brightgreen.svg)](http://socketo.me/reports/rfc-server/index.html)

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 interpretation in the specification are also left open in this library.
It is up to the implementation to determine how those interpretations 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.

PK������h�\�:\Y3��3��$��vendor/psr/http-message/CHANGELOG.mdnu��Iw����������# 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.

PK������h�\#��@������2��vendor/evenement/evenement/doc/02-plugin-system.mdnu��Iw����������# 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.

��*��vendor/evenement/evenement/doc/00-intro.mdnu��Iw����������# 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.
PK������h�\q�Y�������(��vendor/evenement/evenement/doc/01-api.mdnu��Iw����������# 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.

PK������h�\�f8L��L��$��vendor/evenement/evenement/README.mdnu��Iw����������# 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]);
```

/**
 * [Deprecated] An `ext-libevent` based event loop.
 *
 * This uses the [`libevent` PECL extension](https://pecl.php.net/package/libevent),
 * that provides an interface to `libevent` library.
 * `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.
 *
 * @link https://pecl.php.net/package/libevent
 * @deprecated 1.2.0, use [`ExtEventLoop`](#exteventloop) instead.

/**
 * A `stream_select()` based event loop.
 *
 * This uses the [`stream_select()`](https://www.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
 * when using any version before PHP 7.3, because a monotonic time source is
 * only available as of PHP 7.3 (`hrtime()`).
 * While this does not affect many common use cases, this is an important
 * distinction for programs that rely on a high time precision or on systems
 * that are subject to discontinuous time adjustments (time jumps).
 * This means that if you schedule a timer to trigger in 30s on PHP < 7.3 and
 * then adjust your system time forward by 20s, the timer may trigger in 10s.
 * See also [`addTimer()`](#addtimer) for more details.

## 1.2.0 (2021-07-11)

A major new feature release, see [**release announcement**](https://clue.engineering/2021/announcing-reactphp-default-loop).

*   Feature: Introduce new concept of default loop with the new `Loop` class.
    (#226 by @WyriHaximus, #229, #231 and #232 by @clue)

The `Loop` class exists as a convenient global accessor for the event loop.
    It provides all methods that exist on the `LoopInterface` as static methods and
    will automatically execute the loop at the end of the program:

```php
    $timer = Loop::addPeriodicTimer(0.1, function () {
        echo 'Tick' . PHP_EOL;
    });

Loop::addTimer(1.0, function () use ($timer) {
        Loop::cancelTimer($timer);
        echo 'Done' . PHP_EOL;
    });
    ```

The explicit loop instructions are still valid and may still be useful in some applications,
    especially for a transition period towards the more concise style.
    The `Loop::get()` method can be used to get the currently active event loop instance.

```php
    // deprecated
    $loop = React\EventLoop\Factory::create();

// new
    $loop = React\EventLoop\Loop::get();
    ```

*   Minor documentation improvements and mark legacy extensions as deprecated.
    (#234 by @SimonFrings, #214 by @WyriHaximus and #233 and #235 by @nhedger)

*   Improve test suite, use GitHub actions for continuous integration (CI),
    update PHPUnit config and run tests on PHP 8.
    (#212 and #215 by @SimonFrings and #230 by @clue)

## 1.1.1 (2020-01-01)

*   Fix: Fix reporting connection refused errors with `ExtUvLoop` on Linux and `StreamSelectLoop` on Windows.
    (#207 and #208 by @clue)

*   Fix: Fix unsupported EventConfig and `SEGFAULT` on shutdown with `ExtEventLoop` on Windows.
    (#205 by @clue)

*   Fix: Prevent interval overflow for timers very far in the future with `ExtUvLoop`.
    (#196 by @PabloKowalczyk)

*   Fix: Check PCNTL functions for signal support instead of PCNTL extension with `StreamSelectLoop`.
    (#195 by @clue)

*   Add `.gitattributes` to exclude dev files from exports.
    (#201 by @reedy)

*   Improve test suite to fix testing `ExtUvLoop` on Travis,
    fix Travis CI builds, do not install `libuv` on legacy PHP setups,
    fix failing test cases due to inaccurate timers,
    run tests on Windows via Travis CI and
    run tests on PHP 7.4 and simplify test matrix and test setup.
    (#197 by @WyriHaximus and #202, #203, #204 and #209 by @clue)

## 1.1.0 (2019-02-07)

*   New UV based event loop (ext-uv).
    (#112 by @WyriHaximus)

*   Use high resolution timer on PHP 7.3+. 
    (#182 by @clue)

*   Improve PCNTL signals by using async signal dispatching if available. 
    (#179 by @CharlotteDunois)

*   Improve test suite and test suite set up.
    (#174 by @WyriHaximus, #181 by @clue)

*   Fix PCNTL signals edge case. 
    (#183 by @clue)

## 1.0.0 (2018-07-11)

*   First stable LTS release, now following [SemVer](https://semver.org/).
    We'd like to emphasize that this component is production ready and battle-tested.
    We plan to support all long-term support (LTS) releases for at least 24 months,
    so you have a rock-solid foundation to build on top of.

>   Contains no other changes, so it's actually fully compatible with the v0.5.3 release.

## 0.5.3 (2018-07-09)

*   Improve performance by importing global functions.
    (#167 by @Ocramius)

*   Improve test suite by simplifying test bootstrap by using dev autoloader.
    (#169 by @lcobucci)

*   Minor internal changes to improved backward compatibility with PHP 5.3.
    (#166 by @Donatello-za)

## 0.5.2 (2018-04-24)

*   Feature: Improve memory consumption and runtime performance for `StreamSelectLoop` timers.
    (#164 by @clue)

*   Improve test suite by removing I/O dependency at `StreamSelectLoopTest` to fix Mac OS X tests.
    (#161 by @nawarian)

## 0.5.1 (2018-04-09)

*   Feature: New `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)

[![CI status](https://github.com/reactphp/event-loop/workflows/CI/badge.svg)](https://github.com/reactphp/event-loop/actions)

[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
<?php

use React\EventLoop\Loop;

require __DIR__ . '/vendor/autoload.php';

$server = stream_socket_server('tcp://127.0.0.1:8080');
stream_set_blocking($server, false);

Loop::addReadStream($server, function ($server) {
    $conn = stream_socket_accept($server);
    $data = "HTTP/1.1 200 OK\r\nContent-Length: 3\r\n\r\nHi\n";
    Loop::addWriteStream($conn, function ($conn) use (&$data) {
        $written = fwrite($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";
});
```

See also the [examples](examples).

## Usage

As of `v1.2.0`, typical applications would use the [`Loop` object](#loop)
to use the currently active event loop like this:

```php
use React\EventLoop\Loop;

$timer = Loop::addPeriodicTimer(0.1, function () {
    echo 'Tick' . PHP_EOL;
});

Loop::addTimer(1.0, function () use ($timer) {
    Loop::cancelTimer($timer);
    echo 'Done' . PHP_EOL;
});
```

As an alternative, you can also explicitly create an event loop instance at the
beginning, reuse it throughout your program and finally run it at the end of the
program like this:

```php
$loop = React\EventLoop\Loop::get(); // or deprecated React\EventLoop\Factory::create();

$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;
});

$loop->run();
```

While the former is more concise, the latter is more explicit.
In both cases, the program would perform the exact same steps.

1. The event loop instance is created at the beginning of the program. This is
   implicitly done the first time you call the [`Loop` class](#loop) or
   explicitly when using the deprecated [`Factory::create() method`](#create)
   (or manually instantiating any of the [loop implementations](#loop-implementations)).
2. The event loop is used directly or passed as an instance to library and
   application code. In this example, a periodic timer is registered with the
   event loop which simply outputs `Tick` every fraction of a second until another
   timer stops the periodic timer after a second.
3. The event loop is run at the end of the program. This is automatically done
   when using [`Loop` class](#loop) or explicitly with a single [`run()`](#run)
   call at the end of the program.

As of `v1.2.0`, we highly recommend using the [`Loop` class](#loop).
The explicit loop instructions are still valid and may still be useful in some
applications, especially for a transition period towards the more concise style.

### Loop

The `Loop` class exists as a convenient global accessor for the event loop.

#### Loop methods

The `Loop` class provides all methods that exist on the [`LoopInterface`](#loopinterface)
as static methods:

* [run()](#run)
* [stop()](#stop)
* [addTimer()](#addtimer)
* [addPeriodicTimer()](#addperiodictimer)
* [cancelTimer()](#canceltimer)
* [futureTick()](#futuretick)
* [addSignal()](#addsignal)
* [removeSignal()](#removesignal)
* [addReadStream()](#addreadstream)
* [addWriteStream()](#addwritestream)
* [removeReadStream()](#removereadstream)
* [removeWriteStream()](#removewritestream)

If you're working with the event loop in your application code, it's often
easiest to directly interface with the static methods defined on the `Loop` class
like this:

```php
use React\EventLoop\Loop;

$timer = Loop::addPeriodicTimer(0.1, function () {
    echo 'Tick' . PHP_EOL;
});

Loop::addTimer(1.0, function () use ($timer) {
    Loop::cancelTimer($timer);
    echo 'Done' . PHP_EOL;
});
```

On the other hand, if you're familiar with object-oriented programming (OOP) and
dependency injection (DI), you may want to inject an event loop instance and
invoke instance methods on the `LoopInterface` like this:

```php
use React\EventLoop\Loop;
use React\EventLoop\LoopInterface;

class Greeter
{
    private $loop;

public function __construct(LoopInterface $loop)
    {
        $this->loop = $loop;
    }

public function greet(string $name)
    {
        $this->loop->addTimer(1.0, function () use ($name) {
            echo 'Hello ' . $name . '!' . PHP_EOL;
        });
    }
}

$greeter = new Greeter(Loop::get());
$greeter->greet('Alice');
$greeter->greet('Bob');
```

Each static method call will be forwarded as-is to the underlying event loop
instance by using the [`Loop::get()`](#get) call internally.
See [`LoopInterface`](#loopinterface) for more details about available methods.

#### Loop autorun

When using the `Loop` class, it will automatically execute the loop at the end of
the program. This means the following example will schedule a timer and will
automatically execute the program until the timer event fires:

```php
use React\EventLoop\Loop;

Loop::addTimer(1.0, function () {
    echo 'Hello' . PHP_EOL;
});
```

As of `v1.2.0`, we highly recommend using the `Loop` class this way and omitting any
explicit [`run()`](#run) calls. For BC reasons, the explicit [`run()`](#run)
method is still valid and may still be useful in some applications, especially
for a transition period towards the more concise style.

If you don't want the `Loop` to run automatically, you can either explicitly
[`run()`](#run) or [`stop()`](#stop) it. This can be useful if you're using
a global exception handler like this:

```php
use React\EventLoop\Loop;

Loop::addTimer(10.0, function () {
    echo 'Never happens';
});

set_exception_handler(function (Throwable $e) {
    echo 'Error: ' . $e->getMessage() . PHP_EOL;
    Loop::stop();
});

throw new RuntimeException('Demo');
```

#### get()

The `get(): LoopInterface` method can be used to
get the currently active event loop instance.

This method will always return the same event loop instance throughout the
lifetime of your application.

```php
use React\EventLoop\Loop;
use React\EventLoop\LoopInterface;

$loop = Loop::get();

assert($loop instanceof LoopInterface);
assert($loop === Loop::get());
```

This is particularly useful if you're using object-oriented programming (OOP)
and dependency injection (DI). In this case, you may want to inject an event
loop instance and invoke instance methods on the `LoopInterface` like this:

```php
use React\EventLoop\Loop;
use React\EventLoop\LoopInterface;

class Greeter
{
    private $loop;

public function __construct(LoopInterface $loop)
    {
        $this->loop = $loop;
    }

public function greet(string $name)
    {
        $this->loop->addTimer(1.0, function () use ($name) {
            echo 'Hello ' . $name . '!' . PHP_EOL;
        });
    }
}

$greeter = new Greeter(Loop::get());
$greeter->greet('Alice');
$greeter->greet('Bob');
```

See [`LoopInterface`](#loopinterface) for more details about available methods.

### ~~Factory~~

> Deprecated since v1.2.0, see [`Loop` class](#loop) instead.

The deprecated `Factory` class exists as a convenient way to pick the best available
[event loop implementation](#loop-implementations).

#### ~~create()~~

> Deprecated since v1.2.0, see [`Loop::get()`](#get) instead.

The deprecated `create(): LoopInterface` method can be used to
create a new event loop instance:

```php
// deprecated
$loop = React\EventLoop\Factory::create();

// new
$loop = React\EventLoop\Loop::get();
```

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()`](https://www.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
when using any version before PHP 7.3, because a monotonic time source is
only available as of PHP 7.3 (`hrtime()`).
While this does not affect many common use cases, this is an important
distinction for programs that rely on a high time precision or on systems
that are subject to discontinuous time adjustments (time jumps).
This means that if you schedule a timer to trigger in 30s on PHP < 7.3 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),
that provides an interface to `libevent` library.
`libevent` itself supports a number of system-specific backends (epoll, kqueue).

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.
`libev` itself supports a number of system-specific backends (epoll, kqueue).

This loop is known to work with PHP 5.4 through PHP 7+.

#### ExtUvLoop

An `ext-uv` based event loop.

This loop uses the [`uv` PECL extension](https://pecl.php.net/package/uv),
that provides an interface to `libuv` library.
`libuv` itself supports a number of system-specific backends (epoll, kqueue).

This loop is known to work with PHP 7+.

#### ~~ExtLibeventLoop~~

> Deprecated since v1.2.0, use [`ExtEventLoop`](#exteventloop) instead.

An `ext-libevent` based event loop.

This uses the [`libevent` PECL extension](https://pecl.php.net/package/libevent),
that provides an interface to `libevent` library.
`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~~

> Deprecated since v1.2.0, use [`ExtEvLoop`](#extevloop) instead.

An `ext-libev` based event loop.

This uses an [unofficial `libev` extension](https://github.com/m4rw3r/php-libev),
that provides an interface to `libev` library.
`libev` itself supports a number of system-specific backends (epoll, kqueue).

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 the [examples](examples).

Here's a client that outputs the output of said server and then attempts to
send it a string:

```php
$connector = new React\Socket\Connector();

$connector->connect('127.0.0.1:8080')->then(function (React\Socket\ConnectionInterface $connection) {
    $connection->pipe(new React\Stream\WritableResourceStream(STDOUT));
    $connection->write("Hello World!\n");
}, function (Exception $e) {
    echo 'Error: ' . $e->getMessage() . PHP_EOL;
});
```

## 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.

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
$socket->on('connection', function (React\Socket\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
$socket->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 = $socket->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 = $socket->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
$socket->pause();

$socket->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
$socket->pause();

Loop::addTimer(1.0, function () use ($socket) {
    $socket->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;
$socket->close();
```

Calling this method more than once on the same instance is a NO-OP.

### SocketServer

The `SocketServer` 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.

In order to accept plaintext TCP/IP connections, you can simply pass a host
and port combination like this:

```php
$socket = new React\Socket\SocketServer('127.0.0.1:8080');
```

Listening on the localhost address `127.0.0.1` means it will not be reachable from
outside of this system.
In order to change the host the socket is listening on, you can provide an IP
address of an interface or use the special `0.0.0.0` address to listen on all
interfaces:

```php
$socket = new React\Socket\SocketServer('0.0.0.0:8080');
```

If you want to listen on an IPv6 address, you MUST enclose the host in square
brackets:

```php
$socket = new React\Socket\SocketServer('[::1]:8080');
```

In order to use a random port assignment, you can use the port `0`:

```php
$socket = new React\Socket\SocketServer('127.0.0.1:0');
$address = $socket->getAddress();
```

To listen on a Unix domain socket (UDS) path, you MUST prefix the URI with the
`unix://` scheme:

```php
$socket = new React\Socket\SocketServer('unix:///tmp/server.sock');
```

In order to listen on an existing file descriptor (FD) number, you MUST prefix
the URI with `php://fd/` like this:

```php
$socket = new React\Socket\SocketServer('php://fd/3');
```

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
$socket = new React\Socket\SocketServer('127.0.0.1');
```

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 React\Socket\SocketServer('127.0.0.1:8080');

// throws RuntimeException because port is already in use
$second = new React\Socket\SocketServer('127.0.0.1:8080');
```

> 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](https://www.php.net/manual/en/context.socket.php)
for the underlying stream socket resource like this:

```php
$socket = new React\Socket\SocketServer('[::1]:8080', array(
    'tcp' => array(
        'backlog' => 200,
        'so_reuseport' => true,
        'ipv6_v6only' => true
    )
));
```

> Note that available [socket context options](https://www.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.
  The `backlog` context option defaults to `511` unless given explicitly.

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](https://www.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
$socket = new React\Socket\SocketServer('tls://127.0.0.1:8080', 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
$socket = new React\Socket\SocketServer('tls://127.0.0.1:8000', 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
$socket = new React\Socket\SocketServer('tls://127.0.0.1:8000', array(
    'tls' => array(
        'local_cert' => 'server.pem',
        'crypto_method' => STREAM_CRYPTO_METHOD_TLSv1_2_SERVER
    )
));
```

> Note that available [TLS context options](https://www.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
$socket->on('connection', function (React\Socket\ConnectionInterface $connection) {
    echo 'Plaintext connection from ' . $connection->getRemoteAddress() . PHP_EOL;
    
    $connection->write('hello there!' . PHP_EOL);
    …
});
```

See also the [`ServerInterface`](#serverinterface) for more details.

This class takes an optional `LoopInterface|null $loop` parameter that can be used to
pass the event loop instance to use for this object. You can use a `null` value
here in order to use the [default loop](https://github.com/reactphp/event-loop#loop).
This value SHOULD NOT be given unless you're sure you want to explicitly use a
given event loop instance.

> Note that the `SocketServer` 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.

> Changelog v1.9.0: This class has been added with an improved constructor signature
  as a replacement for the previous `Server` class in order to avoid any ambiguities.
  The previous name has been deprecated and should not be used anymore.

### Advanced server usage

#### TcpServer

The `TcpServer` class implements the [`ServerInterface`](#serverinterface) and
is responsible for accepting plaintext TCP/IP connections.

```php
$server = new React\Socket\TcpServer(8080);
```

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 React\Socket\TcpServer(0);
$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 React\Socket\TcpServer('192.168.0.1:8080');
```

If you want to listen on an IPv6 address, you MUST enclose the host in square
brackets:

```php
$server = new React\Socket\TcpServer('[::1]:8080');
```

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 React\Socket\TcpServer('127.0.0.1');
```

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 React\Socket\TcpServer(8080);

// throws RuntimeException because port is already in use
$second = new React\Socket\TcpServer(8080);
```

> 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 [socket context options](https://www.php.net/manual/en/context.socket.php)
for the underlying stream socket resource like this:

```php
$server = new React\Socket\TcpServer('[::1]:8080', null, array(
    'backlog' => 200,
    'so_reuseport' => true,
    'ipv6_v6only' => true
));
```

> Note that available [socket context options](https://www.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.
The `backlog` context option defaults to `511` unless given explicitly.

Whenever a client connects, it will emit a `connection` event with a connection
instance implementing [`ConnectionInterface`](#connectioninterface):

```php
$server->on('connection', function (React\Socket\ConnectionInterface $connection) {
    echo 'Plaintext connection from ' . $connection->getRemoteAddress() . PHP_EOL;
    
    $connection->write('hello there!' . PHP_EOL);
    …
});
```

See also the [`ServerInterface`](#serverinterface) for more details.

#### SecureServer

The `SecureServer` class implements the [`ServerInterface`](#serverinterface)
and is responsible for providing a secure TLS (formerly known as SSL) server.

It does so by wrapping a [`TcpServer`](#tcpserver) instance which waits for plaintext
TCP/IP connections and then performs a TLS handshake for each connection.
It thus requires valid [TLS context options](https://www.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 React\Socket\TcpServer(8000);
$server = new React\Socket\SecureServer($server, null, 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 React\Socket\TcpServer(8000);
$server = new React\Socket\SecureServer($server, null, 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 React\Socket\TcpServer(8000);
$server = new React\Socket\SecureServer($server, null, array(
    'local_cert' => 'server.pem',
    'crypto_method' => STREAM_CRYPTO_METHOD_TLSv1_2_SERVER
));
```

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 (React\Socket\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 React\Socket\UnixServer('/tmp/server.sock');
```

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 React\Socket\UnixServer('/tmp/same.sock');

// throws RuntimeException because socket is already in use
$second = new React\Socket\UnixServer('/tmp/same.sock');
```

> Note that these error conditions may vary depending on your system and/or
  configuration.
  In particular, Zend PHP does only report "Unknown error" when the UDS path
  already exists and can not be bound. You may want to check `is_file()` on the
  given UDS path to report a more user-friendly error message in this case.
  See the exception message and code for more details about the actual error
  condition.

Whenever a client connects, it will emit a `connection` event with a connection
instance implementing [`ConnectionInterface`](#connectioninterface):

```php
$server->on('connection', function (React\Socket\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
$server = new React\Socket\LimitingServer($server, 100);
$server->on('connection', function (React\Socket\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.

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
$server = new React\Socket\LimitingServer($server, 100, true);
$server->on('connection', function (React\Socket\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 (React\Socket\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
$connector = new React\Socket\Connector();

$connector->connect($uri)->then(function (React\Socket\ConnectionInterface $connection) {
    $connection->write('...');
    $connection->end();
}, function (Exception $e) {
    echo 'Error: ' . $e->getMessage() . PHP_EOL;
});
```

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 (React\Socket\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 (React\Socket\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 (React\Socket\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.

As of `v1.4.0`, the `Connector` class defaults to using the
[happy eyeballs algorithm](https://en.wikipedia.org/wiki/Happy_Eyeballs) to
automatically connect over IPv4 or IPv6 when a hostname is given.
This automatically attempts to connect using both IPv4 and IPv6 at the same time
(preferring IPv6), thus avoiding the usual problems faced by users with imperfect
IPv6 connections or setups.
If you want to revert to the old behavior of only doing an IPv4 lookup and
only attempt a single IPv4 connection, you can set up the `Connector` like this:

```php
$connector = new React\Socket\Connector(array(
    'happy_eyeballs' => false
));
```

Similarly, you can also affect the default DNS behavior as follows.
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 React\Socket\Connector(array(
    'dns' => '127.0.1.1'
));

$connector->connect('localhost:80')->then(function (React\Socket\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 React\Socket\Connector(array(
    'dns' => false
));

$connector->connect('127.0.0.1:80')->then(function (React\Socket\ConnectionInterface $connection) {
    $connection->write('...');
    $connection->end();
});
```

Advanced: If you need a custom DNS `React\Dns\Resolver\ResolverInterface` instance, you
can also set up your `Connector` like this:

```php
$dnsResolverFactory = new React\Dns\Resolver\Factory();
$resolver = $dnsResolverFactory->createCached('127.0.1.1');

$connector = new React\Socket\Connector(array(
    'dns' => $resolver
));

$connector->connect('localhost:80')->then(function (React\Socket\ConnectionInterface $connection) {
    $connection->write('...');
    $connection->end();
});
```

By default, the `tcp://` and `tls://` URI schemes will use timeout value that
respects 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 React\Socket\Connector(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 React\Socket\Connector(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 React\Socket\Connector(array(
    'tcp' => false,
    'tls' => true,
    'unix' => false,
));

$connector->connect('tls://google.com:443')->then(function (React\Socket\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 React\Socket\Connector(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 (React\Socket\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 React\Socket\Connector(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](https://www.php.net/manual/en/context.socket.php)
  and [SSL context options](https://www.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');
$tcp = new React\Socket\HappyEyeBallsConnector(null, new React\Socket\TcpConnector(), $resolver);

$tls = new React\Socket\SecureConnector($tcp);

$unix = new React\Socket\UnixConnector();

$connector = new React\Socket\Connector(array(
    'tcp' => $tcp,
    'tls' => $tls,
    'unix' => $unix,

'dns' => false,
    'timeout' => false,
));

$connector->connect('google.com:80')->then(function (React\Socket\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.

> Changelog v1.9.0: The constructur signature has been updated to take the
> optional `$context` as the first parameter and the optional `$loop` as a second
> argument. The previous signature has been deprecated and should not be used anymore.

### Advanced client usage

#### TcpConnector

The `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();

$tcpConnector->connect('127.0.0.1:80')->then(function (React\Socket\ConnectionInterface $connection) {
    $connection->write('...');
    $connection->end();
});
```

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](https://www.php.net/manual/en/context.socket.php)
to the constructor like this:

```php
$tcpConnector = new React\Socket\TcpConnector(null, 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.

#### HappyEyeBallsConnector

The `HappyEyeBallsConnector` class implements the
[`ConnectorInterface`](#connectorinterface) and allows you to create plaintext
TCP/IP connections to any hostname-port-combination. Internally it implements the 
happy eyeballs algorithm from [`RFC6555`](https://tools.ietf.org/html/rfc6555) and 
[`RFC8305`](https://tools.ietf.org/html/rfc8305) to support IPv6 and IPv4 hostnames.

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');

$dnsConnector = new React\Socket\HappyEyeBallsConnector(null, $tcpConnector, $dns);

$dnsConnector->connect('www.google.com:80')->then(function (React\Socket\ConnectionInterface $connection) {
    $connection->write('...');
    $connection->end();
});
```

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 lookups
and/or the underlying TCP/IP connection(s) and reject the resulting promise.

> Advanced usage: Internally, the `HappyEyeBallsConnector` relies on a `Resolver` to
look up the IP addresses for the given hostname.
It will then replace the hostname in the destination URI with this IP's and
append a `hostname` query parameter and pass this updated URI to the underlying
connector. 
The Happy Eye Balls algorithm describes looking the IPv6 and IPv4 address for 
the given hostname so this connector sends out two DNS lookups for the A and 
AAAA records. It then uses all IP addresses (both v6 and v4) and tries to 
connect to all of them with a 50ms interval in between. Alterating between IPv6 
and IPv4 addresses. When a connection is established all the other DNS lookups 
and connection attempts are cancelled.

#### DnsConnector

The `DnsConnector` class implements the
[`ConnectorInterface`](#connectorinterface) and allows you to create plaintext
TCP/IP connections to any hostname-port-combination.

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');

$dnsConnector = new React\Socket\DnsConnector($tcpConnector, $dns);

$dnsConnector->connect('www.google.com:80')->then(function (React\Socket\ConnectionInterface $connection) {
    $connection->write('...');
    $connection->end();
});
```

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 `React\Dns\Resolver\ResolverInterface`
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);

$secureConnector->connect('www.google.com:443')->then(function (React\Socket\ConnectionInterface $connection) {
    $connection->write("GET / HTTP/1.0\r\nHost: www.google.com\r\n\r\n");
    ...
});
```

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](https://www.php.net/manual/en/context.ssl.php)
to the constructor like this:

```php
$secureConnector = new React\Socket\SecureConnector($dnsConnector, null, 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, null, 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);

$timeoutConnector->connect('google.com:80')->then(function (React\Socket\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();

$connector->connect('/tmp/demo.sock')->then(function (React\Socket\ConnectionInterface $connection) {
    $connection->write("HELLO\n");
});
```

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 React\Socket\FixedUriConnector(
    'unix:///var/run/docker.sock',
    new React\Socket\UnixConnector()
);

// 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 project follows [SemVer](https://semver.org/).
This will install the latest supported version:

```bash
$ composer require react/socket:^1.10
```

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 8+ and HHVM.
It's *highly recommended to use the latest supported PHP version* 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.

PHP < 7.3.3 (and PHP < 7.2.15) suffers from a bug where feof() might
block with 100% CPU usage on fragmented TLS records.
We try to work around this by always consuming the complete receive
buffer at once to avoid stale data in TLS buffers. This is known to
work around high CPU usage for well-behaving peers, but this may
cause very large data chunks for high throughput scenarios. The buggy
behavior can still be triggered due to network I/O buffers or
malicious peers on affected versions, upgrading is highly recommended.

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
$ 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
$ vendor/bin/phpunit --exclude-group internet
```

/**
 * 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.
 *
 * This function takes an optional `LoopInterface|null $loop` parameter that can be used to
 * pass the event loop instance to use. You can use a `null` value here in order to
 * use the [default loop](https://github.com/reactphp/event-loop#loop). This value
 * SHOULD NOT be given unless you're sure you want to explicitly use a given event
 * loop instance.
 *
 * A common use case for handling only resolved values looks like this:
 *
 * ```php
 * $promise = accessSomeRemoteResource();
 * React\Promise\Timer\timeout($promise, 10.0)->then(function ($value) {
 *     // the operation finished within 10.0 seconds
 * });
 * ```
 *
 * A more complete example could look like this:
 *
 * ```php
 * $promise = accessSomeRemoteResource();
 * React\Promise\Timer\timeout($promise, 10.0)->then(
 *     function ($value) {
 *         // the operation finished within 10.0 seconds
 *     },
 *     function ($error) {
 *         if ($error instanceof React\Promise\Timer\TimeoutException) {
 *             // the operation has failed due to a timeout
 *         } else {
 *             // the input operation has failed due to some other error
 *         }
 *     }
 * );
 * ```
 *
 * Or if you're using [react/promise v2.2.0](https://github.com/reactphp/promise) or up:
 *
 * ```php
 * React\Promise\Timer\timeout($promise, 10.0)
 *     ->then(function ($value) {
 *         // the operation finished within 10.0 seconds
 *     })
 *     ->otherwise(function (React\Promise\Timer\TimeoutException $error) {
 *         // the operation has failed due to a timeout
 *     })
 *     ->otherwise(function ($error) {
 *         // the input operation has failed due to some other error
 *     })
 * ;
 * ```
 *
 * As discussed above, the [`timeout()`](#timeout) function will take care of
 * the underlying operation if it takes *too long*. In this case, you can be
 * sure the resulting promise will always be rejected with a
 * [`TimeoutException`](#timeoutexception). On top of this, the function will
 * try to *cancel* the underlying operation. Responsibility for this
 * cancellation logic is left up to the underlying operation.
 *
 * - 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
 *
 * On top of this, the returned promise is implemented in such a way that it can
 * be cancelled when it is still pending. Cancelling a pending promise will
 * cancel the underlying operation. As discussed above, responsibility for this
 * cancellation logic is left up to the underlying operation.
 *
 * ```php
 * $promise = accessSomeRemoteResource();
 * $timeout = React\Promise\Timer\timeout($promise, 10.0);
 *
 * $timeout->cancel();
 * ```
 *
 * For more details on the promise cancellation, please refer to the
 * [Promise documentation](https://github.com/reactphp/promise#cancellablepromiseinterface).
 *
 * 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);
 *
 * React\Promise\Timer\timeout($promise, 10)->then(function ($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).

## Usage

This lightweight library consists only of a few simple functions.
All functions reside under the `React\Promise\Timer` namespace.

The below examples refer to all functions with their fully-qualified names like this:

```php
React\Promise\Timer\timeout(…);
```

As of PHP 5.6+ you can also import each required function into your code like this:

```php
use function React\Promise\Timer\timeout;

timeout(…);
```

Alternatively, you can also use an import statement similar to this:

```php
use React\Promise\Timer;

Timer\timeout(…);
```

### timeout()

The `timeout(PromiseInterface<mixed, Exception|mixed> $promise, float $time, ?LoopInterface $loop = null): PromiseInterface<mixed, TimeoutException|Exception|mixed>` 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.

This function takes an optional `LoopInterface|null $loop` parameter that can be used to
pass the event loop instance to use. You can use a `null` value here in order to
use the [default loop](https://github.com/reactphp/event-loop#loop). This value
SHOULD NOT be given unless you're sure you want to explicitly use a given event
loop instance.

A common use case for handling only resolved values looks like this:

```php
$promise = accessSomeRemoteResource();
React\Promise\Timer\timeout($promise, 10.0)->then(function ($value) {
    // the operation finished within 10.0 seconds
});
```

A more complete example could look like this:

```php
$promise = accessSomeRemoteResource();
React\Promise\Timer\timeout($promise, 10.0)->then(
    function ($value) {
        // the operation finished within 10.0 seconds
    },
    function ($error) {
        if ($error instanceof React\Promise\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
React\Promise\Timer\timeout($promise, 10.0)
    ->then(function ($value) {
        // the operation finished within 10.0 seconds
    })
    ->otherwise(function (React\Promise\Timer\TimeoutException $error) {
        // the operation has failed due to a timeout
    })
    ->otherwise(function ($error) {
        // the input operation has failed due to some other error
    })
;
```

As discussed above, the [`timeout()`](#timeout) function will take care of
the underlying operation if it takes *too long*. In this case, you can be
sure the resulting promise will always be rejected with a
[`TimeoutException`](#timeoutexception). On top of this, the function will
try to *cancel* the underlying operation. Responsibility for this
cancellation logic is left up to the underlying operation.

- 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

On top of this, the returned promise is implemented in such a way that it can
be cancelled when it is still pending. Cancelling a pending promise will
cancel the underlying operation. As discussed above, responsibility for this
cancellation logic is left up to the underlying operation.

```php
$promise = accessSomeRemoteResource();
$timeout = React\Promise\Timer\timeout($promise, 10.0);

$timeout->cancel();
```

For more details on the promise cancellation, please refer to the
[Promise documentation](https://github.com/reactphp/promise#cancellablepromiseinterface).

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);

React\Promise\Timer\timeout($promise, 10)->then(function ($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).

### sleep()

The `sleep(float $time, ?LoopInterface $loop = null): PromiseInterface<void, RuntimeException>` function can be used to
create a new promise that resolves in `$time` seconds.

```php
React\Promise\Timer\sleep(1.5)->then(function () {
    echo 'Thanks for waiting!' . 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.

The returned promise is implemented in such a way that it can be cancelled
when it is still pending. Cancelling a pending promise will reject its value
with a `RuntimeException` and clean up any pending timers.

```php
$timer = React\Promise\Timer\sleep(2.0);

$timer->cancel();
```

### ~~resolve()~~

> Deprecated since v1.8.0, see [`sleep()`](#sleep) instead.

The `resolve(float $time, ?LoopInterface $loop = null): PromiseInterface<float, RuntimeException>` function can be used to
create a new promise that resolves in `$time` seconds with the `$time` as the fulfillment value.

```php
React\Promise\Timer\resolve(1.5)->then(function ($time) {
    echo 'Thanks for waiting ' . $time . ' seconds' . PHP_EOL;
});
```

```php
$timer = React\Promise\Timer\resolve(2.0);

$timer->cancel();
```

### ~~reject()~~

> Deprecated since v1.8.0, see [`sleep()`](#sleep) instead.

The `reject(float $time, ?LoopInterface $loop = null): PromiseInterface<void, TimeoutException|RuntimeException>` function can be used to
create a new promise which rejects in `$time` seconds with a `TimeoutException`.

```php
React\Promise\Timer\reject(2.0)->then(null, function (React\Promise\Timer\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.

```php
$timer = React\Promise\Timer\reject(2.0);

$timer->cancel();
```

### TimeoutException

The `TimeoutException` extends PHP's built-in `RuntimeException`.

#### getTimeout()

The `getTimeout(): float` method can be used to
get the timeout value in seconds.

 * The `ThroughStream` implements the

 *
 * ```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) {

 * $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) {

/**
 * 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.

/**
     * Successfully ends 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');

     * 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.

     *
     * ```php
     * $stream->close();

/**
 * 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.

     *
     * ```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.
     *
     * @param WritableStreamInterface $dest
     * @param array $options
     * @return WritableStreamInterface $dest stream as-is
     */

     *
     * 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.

     * ```
     *
     * 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

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

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

PK������h�\S(�5���5�� ��vendor/react/stream/CHANGELOG.mdnu��Iw����������# Changelog

## 1.2.0 (2021-07-11)

A major new feature release, see [**release announcement**](https://clue.engineering/2021/announcing-reactphp-default-loop).

*   Feature: Simplify usage by supporting new [default loop](https://reactphp.org/event-loop/#loop).
    (#159 by @clue)

```php
    // old (still supported)
    $stream = new ReadableResourceStream($resource, $loop);
    $stream = new WritabeResourceStream($resource, $loop);
    $stream = new DuplexResourceStream($resource, $loop);

// new (using default loop)
    $stream = new ReadableResourceStream($resource);
    $stream = new WritabeResourceStream($resource);
    $stream = new DuplexResourceStream($resource);
    ```

*   Improve test suite, use GitHub actions for continuous integration (CI),
    update PHPUnit config, run tests on PHP 8 and add full core team to the license.
    (#153, #156 and #157 by @SimonFrings and #154 by @WyriHaximus)

## 1.1.1 (2020-05-04)

*   Fix: Fix faulty write buffer behavior when sending large data chunks over TLS (Mac OS X only).
    (#150 by @clue)

*   Minor code style improvements to fix phpstan analysis warnings and
    add `.gitattributes` to exclude dev files from exports.
    (#140 by @flow-control and #144 by @reedy)

*   Improve test suite to run tests on PHP 7.4 and simplify test matrix.
    (#147 by @clue)

## 1.1.0 (2019-01-01)

*   Improvement: Increase performance by optimizing global function and constant look ups.
    (#137 by @WyriHaximus)

*   Travis: Test against PHP 7.3.
    (#138 by @WyriHaximus)

*   Fix: Ignore empty reads.
    (#139 by @WyriHaximus)

## 1.0.0 (2018-07-11)

>   Contains no other changes, so it's actually fully compatible with the v0.7.7 release.

## 0.7.7 (2018-01-19)

*   Improve test suite by fixing forward compatibility with upcoming EventLoop

*   Remove `BufferedSink`
        (#45 by @clue)

*   Feature / BC break: Simplify `ThroughStream` by using data callback instead of
    inheritance. It is now a direct implementation of `DuplexStreamInterface`.
    (#88 and #89 by @clue)

```php
    $through = new ThroughStream(function ($data) {
        return json_encode($data) . PHP_EOL;
    });
    $through->on('data', $this->expectCallableOnceWith("[2, true]\n"));

$through->write(array(2, true));
    ```

*   Feature / BC break: The `CompositeStream` starts closed if either side is
    already closed and forwards pause to pipe source on first write attempt.
    (#96 and #103 by @clue)
    
    If either side of the composite stream closes, it will also close the other
    side. We now also ensure that if either side is already closed during
    instantiation, it will also close the other side.

*   BC break: Mark all classes as `final` and
    mark internal API as `private` to discourage inheritance
    (#95 and #99 by @clue)

*   Feature / BC break: Only emit `error` event for fatal errors
    (#92 by @clue)

>   The `error` event was previously also allowed to be emitted for non-fatal
        errors, but our implementations actually only ever emitted this as a fatal
        error and then closed the stream.

*   Feature: Explicitly allow custom events and exclude any semantics
    (#97 by @clue)

*   Strict definition for event callback functions
    (#101 by @clue)

*   Support legacy PHP 5.3 through PHP 7.1 and HHVM and improve usage documentation
    (#100 and #102 by @clue)

*   Actually require all dependencies so this is self-contained and improve
    forward compatibility with EventLoop v1.0 and v0.5
    (#94 and #98 by @clue)

## 0.6.0 (2017-03-26)

* Feature / Fix / BC break: Add `DuplexResourceStream` and deprecate `Stream`
  (#85 by @clue)

```php
  // old (does still work for BC reasons)
  $stream = new Stream($connection, $loop);

// new
  $stream = new DuplexResourceStream($connection, $loop);
  ```

Note that the `DuplexResourceStream` now rejects read-only or write-only
  streams, so this may affect BC. If you want a read-only or write-only
  resource, use `ReadableResourceStream` or `WritableResourceStream` instead of
  `DuplexResourceStream`.

> BC note: This class was previously called `Stream`. The `Stream` class still
    exists for BC reasons and will be removed in future versions of this package.

* Feature / BC break: Add `WritableResourceStream` (previously called `Buffer`)
  (#84 by @clue)

```php
  // old
  $stream = new Buffer(STDOUT, $loop);

// new
  $stream = new WritableResourceStream(STDOUT, $loop);
  ```

* Feature: Add `ReadableResourceStream`
  (#83 by @clue)

```php
  $stream = new ReadableResourceStream(STDIN, $loop);
  ```

* Fix / BC Break: Enforce using non-blocking I/O
  (#46 by @clue)

> BC note: This is known to affect process pipes on Windows which do not
    support non-blocking I/O and could thus block the whole EventLoop previously.

* Feature / Fix / BC break: Consistent semantics for
  `DuplexStreamInterface::end()` to ensure it SHOULD also end readable side
  (#86 by @clue)

* Fix: Do not use unbuffered reads on pipe streams for legacy PHP < 5.4
  (#80 by @clue)

## 0.5.0 (2017-03-08)

* Feature / BC break: Consistent `end` event semantics (EOF)
  (#70 by @clue)
  
  The `end` event will now only be emitted for a *successful* end, not if the
  stream closes due to an unrecoverable `error` event or if you call `close()`
  explicitly.
  If you want to detect when the stream closes (terminates), use the `close`
  event instead.

* BC break: Remove custom (undocumented) `full-drain` event from `Buffer`
  (#63 and #68 by @clue)

> The `full-drain` event was undocumented and mostly used internally.
    Relying on this event has attracted some low-quality code in the past, so
    we've removed this from the public API in order to work out a better
    solution instead.
    If you want to detect when the buffer finishes flushing data to the stream,
    you may want to look into its `end()` method or the `close` event instead.

* Feature / BC break: Consistent event semantics and documentation,
  explicitly state *when* events will be emitted and *which* arguments they
  receive.
  (#73 and #69 by @clue)

The documentation now explicitly defines each event and its arguments.
  Custom events and event arguments are still supported.
  Most notably, all defined events only receive inherently required event
  arguments and no longer transmit the instance they are emitted on for
  consistency and performance reasons.

```php
  // old (inconsistent and not supported by all implementations)
  $stream->on('data', function ($data, $stream) {
      // process $data
  });

// new (consistent throughout the whole ecosystem)
  $stream->on('data', function ($data) use ($stream) {
      // process $data
  });
  ```

> This mostly adds documentation (and thus some stricter, consistent 
    definitions) for the existing behavior, it does NOT define any major
    changes otherwise.
    Most existing code should be compatible with these changes, unless
    it relied on some undocumented/unintended semantics.

* Feature / BC break: Consistent method semantics and documentation
  (#72 by @clue)

> This mostly adds documentation (and thus some stricter, consistent
    definitions) for the existing behavior, it does NOT define any major
    changes otherwise.
    Most existing code should be compatible with these changes, unless
    it relied on some undocumented/unintended semantics.

* Feature: Consistent `pipe()` semantics for closed and closing streams
  (#71 from @clue)

The source stream will now always be paused via `pause()` when the
  destination stream closes. Also, properly stop piping if the source
  stream closes and remove all event forwarding.

* Improve test suite by adding PHPUnit to `require-dev` and improving coverage.
  (#74 and #75 by @clue, #66 by @nawarian)

  (#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)

[![CI status](https://github.com/reactphp/stream/workflows/CI/badge.svg)](https://github.com/reactphp/stream/actions)

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 [example #92](examples).

Note that this executor does not implement a timeout, so you will very likely
want to use this in combination with a `TimeoutExecutor` like this:

```php
$executor = new TimeoutExecutor(
    new TcpTransportExecutor($nameserver),
    3.0
);
```

Unlike the `UdpTransportExecutor`, this class uses a reliable TCP/IP
transport, so you do not necessarily have to implement any retry logic.

Note that this executor is entirely async and as such allows you to execute
queries concurrently. The first query will establish a TCP/IP socket
connection to the DNS server which will be kept open for a short period.
Additional queries will automatically reuse this existing socket connection
to the DNS server, will pipeline multiple requests over this single
connection and will keep an idle connection open for a short period. The
initial TCP/IP connection overhead may incur a slight delay if you only send
occasional queries – when sending a larger number of concurrent queries over
an existing connection, it becomes increasingly more efficient and avoids
creating many concurrent sockets like the UDP-based executor. You may still
want to limit the number of (concurrent) queries in your application or you
may be facing rate limitations and bans on the resolver end. For many common
applications, you may want to avoid sending the same query multiple times
when the first one is still pending, so you will likely want to use this in
combination with a `CoopExecutor` like this:

```php
$executor = new CoopExecutor(
    new TimeoutExecutor(
        new TcpTransportExecutor($nameserver),
        3.0
    )
);
```

> Internally, this class uses PHP's TCP/IP sockets and does not take advantage
  of [react/socket](https://github.com/reactphp/socket) purely for
  organizational reasons to avoid a cyclic dependency between the two
  packages. Higher-level components should take advantage of the Socket
  component instead of reimplementing this socket logic from scratch.

### SelectiveTransportExecutor

The `SelectiveTransportExecutor` class can be used to
Send DNS queries over a UDP or TCP/IP stream transport.

This class will automatically choose the correct transport protocol to send
a DNS query to your DNS server. It will always try to send it over the more
efficient UDP transport first. If this query yields a size related issue
(truncated messages), it will retry over a streaming TCP/IP transport.

For more advanced usages one can utilize this class directly.
The following example looks up the `IPv6` address for `reactphp.org`.

```php
$executor = new SelectiveTransportExecutor($udpExecutor, $tcpExecutor);

Note that this executor only implements the logic to select the correct
transport for the given DNS query. Implementing the correct transport logic,
implementing timeouts and any retry logic is left up to the given executors,
see also [`UdpTransportExecutor`](#udptransportexecutor) and
[`TcpTransportExecutor`](#tcptransportexecutor) for more details.

```php
$executor = new CoopExecutor(
    new SelectiveTransportExecutor(
        $datagramExecutor,
        $streamExecutor
    )
);
```

### HostsFileExecutor

Note that the above `UdpTransportExecutor` class always performs an actual DNS query.
If you also want to take entries from your hosts file into account, you may
use this code:

```php
$hosts = \React\Dns\Config\HostsFile::loadFromPathBlocking();

$executor = new UdpTransportExecutor('8.8.8.8:53');
$executor = new HostsFileExecutor($hosts, $executor);

$executor->query(
    new Query('localhost', Message::TYPE_A, Message::CLASS_IN)
);

[![Build Status](https://travis-ci.org/reactphp/cache.svg?branch=master)](https://travis-ci.org/reactphp/cache)

Async, [Promise](https://github.com/reactphp/promise)-based cache interface
for [ReactPHP](https://reactphp.org/).

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

## Usage

### CacheInterface

The `CacheInterface` describes the main interface of this component.
This allows consumers to type hint against the interface and third parties to
provide alternate implementations.

#### get()

The `get(string $key, mixed $default = null): PromiseInterface<mixed>` method can be used to
retrieve an item from the cache.

This method will resolve with the cached value on success or with the
given `$default` value when no item can be found or when an error occurs.
Similarly, an expired cache item (once the time-to-live is expired) is
considered a cache miss.

```php
$cache
    ->get('foo')
    ->then('var_dump');
```

This example fetches the value of the key `foo` and passes it to the
`var_dump` function. You can use any of the composition provided by
[promises](https://github.com/reactphp/promise).

#### set()

The `set(string $key, mixed $value, ?float $ttl = null): PromiseInterface<bool>` method can be used to
store an item in the cache.

This method will resolve with `true` on success or `false` when an error
occurs. If the cache implementation has to go over the network to store
it, it may take a while.

The optional `$ttl` parameter sets the maximum time-to-live in seconds
for this cache item. If this parameter is omitted (or `null`), the item
will stay in the cache for as long as the underlying implementation
supports. Trying to access an expired cache item results in a cache miss,
see also [`get()`](#get).

```php
$cache->set('foo', 'bar', 60);
```

This example eventually sets the value of the key `foo` to `bar`. If it
already exists, it is overridden.

This interface does not enforce any particular TTL resolution, so special
care may have to be taken if you rely on very high precision with
millisecond accuracy or below. Cache implementations SHOULD work on a
best effort basis and SHOULD provide at least second accuracy unless
otherwise noted. Many existing cache implementations are known to provide
microsecond or millisecond accuracy, but it's generally not recommended
to rely on this high precision.

This interface suggests that cache implementations SHOULD use a monotonic
time source if available. Given that a monotonic time source is only
available as of PHP 7.3 by default, cache implementations MAY fall back
to using wall-clock time.
While this does not affect many common use cases, this is an important
distinction for programs that rely on a high time precision or on systems
that are subject to discontinuous time adjustments (time jumps).
This means that if you store a cache item with a TTL of 30s and then
adjust your system time forward by 20s, the cache item SHOULD still
expire in 30s.

#### delete()

The `delete(string $key): PromiseInterface<bool>` method can be used to
delete an item from the cache.

This method will resolve with `true` on success or `false` when an error
occurs. When no item for `$key` is found in the cache, it also resolves
to `true`. If the cache implementation has to go over the network to
delete it, it may take a while.

```php
$cache->delete('foo');
```

This example eventually deletes the key `foo` from the cache. As with
`set()`, this may not happen instantly and a promise is returned to
provide guarantees whether or not the item has been removed from cache.

#### getMultiple()

The `getMultiple(string[] $keys, mixed $default = null): PromiseInterface<array>` method can be used to
retrieve multiple cache items by their unique keys.

This method will resolve with an array of cached values on success or with the
given `$default` value when an item can not be found or when an error occurs.
Similarly, an expired cache item (once the time-to-live is expired) is
considered a cache miss.

```php
$cache->getMultiple(array('name', 'age'))->then(function (array $values) {
    $name = $values['name'] ?? 'User';
    $age = $values['age'] ?? 'n/a';

echo $name . ' is ' . $age . PHP_EOL;
});
```

This example fetches the cache items for the `name` and `age` keys and
prints some example output. You can use any of the composition provided
by [promises](https://github.com/reactphp/promise).

#### setMultiple()

The `setMultiple(array $values, ?float $ttl = null): PromiseInterface<bool>` method can be used to
persist a set of key => value pairs in the cache, with an optional TTL.

This method will resolve with `true` on success or `false` when an error
occurs. If the cache implementation has to go over the network to store
it, it may take a while.

The optional `$ttl` parameter sets the maximum time-to-live in seconds
for these cache items. If this parameter is omitted (or `null`), these items
will stay in the cache for as long as the underlying implementation
supports. Trying to access an expired cache items results in a cache miss,
see also [`getMultiple()`](#getmultiple).

```php
$cache->setMultiple(array('foo' => 1, 'bar' => 2), 60);
```

This example eventually sets the list of values - the key `foo` to `1` value 
and the key `bar` to `2`. If some of the keys already exist, they are overridden.

#### deleteMultiple()

The `setMultiple(string[] $keys): PromiseInterface<bool>` method can be used to
delete multiple cache items in a single operation.

This method will resolve with `true` on success or `false` when an error
occurs. When no items for `$keys` are found in the cache, it also resolves
to `true`. If the cache implementation has to go over the network to
delete it, it may take a while.

```php
$cache->deleteMultiple(array('foo', 'bar, 'baz'));
```

This example eventually deletes keys `foo`, `bar` and `baz` from the cache. 
As with `setMultiple()`, this may not happen instantly and a promise is returned to
provide guarantees whether or not the item has been removed from cache.

#### clear()

The `clear(): PromiseInterface<bool>` method can be used to
wipe clean the entire cache.

This method will resolve with `true` on success or `false` when an error
occurs. If the cache implementation has to go over the network to
delete it, it may take a while.

```php
$cache->clear();
```

This example eventually deletes all keys from the cache. As with `deleteMultiple()`, 
this may not happen instantly and a promise is returned to provide guarantees 
whether or not all the items have been removed from cache.

#### has()

The `has(string $key): PromiseInterface<bool>` method can be used to
determine whether an item is present in the cache.

This method will resolve with `true` on success or `false` when no item can be found 
or when an error occurs. Similarly, an expired cache item (once the time-to-live 
is expired) is considered a cache miss.

```php
$cache
    ->has('foo')
    ->then('var_dump');
```

This example checks if the value of the key `foo` is set in the cache and passes 
the result to the `var_dump` function. You can use any of the composition provided by
[promises](https://github.com/reactphp/promise).

NOTE: It is recommended that has() is only to be used for cache warming type purposes
and not to be used within your live applications operations for get/set, as this method
is subject to a race condition where your has() will return true and immediately after,
another script can remove it making the state of your app out of date.

### ArrayCache

The `ArrayCache` provides an in-memory implementation of the [`CacheInterface`](#cacheinterface).

```php
$cache = new ArrayCache();

$cache->set('foo', 'bar');
```

Its constructor accepts an optional `?int $limit` parameter to limit the
maximum number of entries to store in the LRU cache. If you add more
entries to this instance, it will automatically take care of removing
the one that was least recently used (LRU).

For example, this snippet will overwrite the first value and only store
the last two entries:

```php
$cache = new ArrayCache(2);

$cache->set('foo', '1');
$cache->set('bar', '2');
$cache->set('baz', '3');
```

This cache implementation is known to rely on wall-clock time to schedule
future cache expiration times when using any version before PHP 7.3,
because a monotonic time source is only available as of PHP 7.3 (`hrtime()`).
While this does not affect many common use cases, this is an important
distinction for programs that rely on a high time precision or on systems
that are subject to discontinuous time adjustments (time jumps).
This means that if you store a cache item with a TTL of 30s on PHP < 7.3
and then adjust your system time forward by 20s, the cache item may
expire in 10s. See also [`set()`](#set) for more details.

## Common usage

### Fallback get

A common use case of caches is to attempt fetching a cached value and as a
fallback retrieve it from the original data source if not found. Here is an
example of that:

```php
$cache
    ->get('foo')
    ->then(function ($result) {
        if ($result === null) {
            return getFooFromDb();
        }
        
        return $result;
    })
    ->then('var_dump');
```

First an attempt is made to retrieve the value of `foo`. A callback function is 
registered that will call `getFooFromDb` when the resulting value is null. 
`getFooFromDb` is a function (can be any PHP callable) that will be called if the 
key does not exist in the cache.

`getFooFromDb` can handle the missing key by returning a promise for the
actual value from the database (or any other data source). As a result, this
chain will correctly fall back, and provide the value in both cases.

### Fallback get and set

To expand on the fallback get example, often you want to set the value on the
cache after fetching it from the data source.

```php
$cache
    ->get('foo')
    ->then(function ($result) {
        if ($result === null) {
            return $this->getAndCacheFooFromDb();
        }
        
        return $result;
    })
    ->then('var_dump');

public function getAndCacheFooFromDb()
{
    return $this->db
        ->get('foo')
        ->then(array($this, 'cacheFooFromDb'));
}

public function cacheFooFromDb($foo)
{
    $this->cache->set('foo', $foo);

return $foo;
}
```

By using chaining you can easily conditionally cache the value if it is
fetched from the database.

[![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#server_configuration).

### 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.

### A quick example

```php
<?php
use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;

// Make sure composer dependencies have been installed
    require __DIR__ . '/vendor/autoload.php';

/**
 * chat.php
 * Send any incoming messages to all connected clients (except sender)
 */
class MyChat implements MessageComponentInterface {
    protected $clients;

public function __construct() {
        $this->clients = new \SplObjectStorage;
    }

public function onOpen(ConnectionInterface $conn) {
        $this->clients->attach($conn);
    }

public function onMessage(ConnectionInterface $from, $msg) {
        foreach ($this->clients as $client) {
            if ($from != $client) {
                $client->send($msg);
            }
        }
    }

public function onClose(ConnectionInterface $conn) {
        $this->clients->detach($conn);
    }

public function onError(ConnectionInterface $conn, \Exception $e) {
        $conn->close();
    }
}

// Run the server application through the WebSocket protocol on port 8080
    $app = new Ratchet\App('localhost', 8080);
    $app->route('/chat', new MyChat, array('*'));
    $app->route('/echo', new Ratchet\Server\EchoServer, array('*'));
    $app->run();
```

$ php chat.php

```javascript
    // Then some JavaScript in the browser:
    var conn = new WebSocket('ws://localhost:8080/echo');
    conn.onmessage = function(e) { console.log(e.data); };
    conn.onopen = function(e) { conn.send('Hello Me!'); };
```

The <info>bump</info> command increases the lower limit of your composer.json requirements

accidentally get downgraded due to some other conflict, and can slightly improve
dependency resolution performance as it limits the amount of package versions
Composer has to look at.

Running this blindly on libraries is **NOT** recommended as it will narrow down
your allowed dependencies, which may cause dependency hell for your users.
Running it with <info>--dev-only</info> on libraries may be fine however as dev requirements
are local to the library and do not affect consumers of the package.

This command allows you to edit composer config settings and repositories
in either the local composer.json file or the global config.json file.

Additionally it lets you edit most properties in the local composer.json.

To set a config setting:

<comment>%command.full_name% bin-dir bin/</comment>

To read a config setting:

<comment>%command.full_name% bin-dir</comment>
    Outputs: <info>bin</info>

To edit the global config.json file:

<comment>%command.full_name% --global</comment>

To add a repository:

<comment>%command.full_name% repositories.foo vcs https://bar.com</comment>

To remove a repository (repo is a short alias for repositories):

<comment>%command.full_name% --unset repo.foo</comment>

To disable packagist.org:

<comment>%command.full_name% repo.packagist.org false</comment>

You can alter repositories in the global config.json file by passing in the
<info>--global</info> option.

To add or edit suggested packages you can use:

<comment>%command.full_name% suggest.package reason for the suggestion</comment>

To add or edit extra properties you can use:

<comment>%command.full_name% extra.property value</comment>

Or to add a complex value you can use json with:

<comment>%command.full_name% extra.property --json '{"foo":true, "bar": []}'</comment>

To edit the file in an external editor:

<comment>%command.full_name% --editor</comment>

To choose your editor you can set the "EDITOR" env variable.

To get a list of configuration values in the file:

<comment>%command.full_name% --list</comment>

You can always pass more than one option. As an example, if you want to edit the
global config.json file.

<comment>%command.full_name% --editor --global</comment>

<<<EOT
The <info>create-project</info> command creates a new project from a given
package into a new directory. If executed without params and in a directory
with a composer.json file it installs the packages for the current project.

You can use this command to bootstrap new projects or setup a clean
version-controlled installation for developers of your project.

<info>php composer.phar create-project vendor/project target-directory [version]</info>

You can also specify the version with the package name using = or : as separator.

<info>php composer.phar create-project vendor/project:version target-directory</info>

To install unstable packages, either specify the version you want, or use the
--stability=dev (where dev can be one of RC, beta, alpha or dev).

To setup a developer workable version you should create the project using the source
controlled code by appending the <info>'--prefer-source'</info> flag.

To install a package from another repository than the default one you
can pass the <info>'--repository=https://myrepository.org'</info> flag.

Use this command as a wrapper to run other Composer commands

You can use this to install CLI utilities globally, all you need

COMPOSER_HOME is c:\Users\<user>\AppData\Roaming\Composer on Windows

If your system uses freedesktop.org standards, then it will first check

The require command adds required packages to your composer.json and installs them.

If you do not specify a package, composer will prompt you to search for a package, and given results, provide a list of
matches to require.

If you do not specify a version constraint, composer will choose a suitable one based on the available package versions.

If you do not want to install the new dependencies immediately you can call it with --no-update

To limit the update operation to a few packages, you can list the package(s)
you want to update as such:

<info>php composer.phar update vendor/package1 foo/mypackage [...]</info>

You may also use an asterisk (*) pattern to limit the update operation to package(s)
from a specific vendor:

<info>php composer.phar update vendor/package1 foo/* [...]</info>

To run an update with more restrictive constraints you can use:

<info>php composer.phar update --with vendor/package:1.0.*</info>

To run a partial update with more restrictive constraints you can use the shorthand:

<info>php composer.phar update vendor/package:1.0.*</info>

To select packages names interactively with auto-completion use <info>-i</info>.
