+# Icinga PHP Thirdparty
+
+This project bundles all 3rd party PHP libraries used by Icinga Web products into one piece,
+which can be integrated as library into Icinga Web 2.
+
+## Requirements
+
+* [Icinga Web 2](https://github.com/Icinga/icingaweb2) (>= 2.9)
+* PHP (>= 7.2)
+
+## Installation
+
+Please download the latest release and install it in one of your configured library paths. The default library
+path for Icinga Web 2 installations is: `/usr/share/icinga-php`
+
+Download or clone this repository there (e.g. `/usr/share/icinga-php/vendor`) and you're done.
+
+> **Note**: Do NOT install the GIT master, it will not work! Checking out a
+> branch like `stable/0.10.0` or a tag like `v0.10.0` is fine.
+
+### Examples
+
+**Sample Tarball installation**
+
+```sh
+INSTALL_PATH="/usr/share/icinga-php/vendor"
+INSTALL_VERSION="v0.10.0"
+mkdir "$INSTALL_PATH" \
+&& wget -q "https://github.com/Icinga/icinga-php-thirdparty/archive/$INSTALL_VERSION.tar.gz" -O - \
+   | tar xfz - -C "$INSTALL_PATH" --strip-components 1
+```
+
+**Sample GIT installation**
+
+```
+INSTALL_PATH="/usr/share/icinga-php/vendor"
+INSTALL_VERSION="stable/0.10.0"
+git clone https://github.com/Icinga/icinga-php-thirdparty.git "$INSTALL_PATH" --branch "$INSTALL_VERSION"
+```

+//	1. Enforce API surface and semantic compatibility with 1.9.x branch
+//	2. Improve the module's maintainability by reducing the storage
+//		paths to a single mechanism.
+//	3. Use the same single mechanism to support "private" and "user" data.
+//	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
+//	5. Avoid exposing implementation details on user objects (eg. expando properties)
+//	6. Provide a clear path for implementation upgrade to WeakMap in 2014

+ *
+ * [you] -> [proxy] -> [destination]
+ *
+ * This is most frequently used to issue HTTPS requests to your destination.
+ * However, this is actually performed on a higher protocol layer and this
+ * connector is actually inherently a general-purpose plain TCP/IP connector.
+ *
+ * Note that HTTP CONNECT proxies often restrict which ports one may connect to.
+ * Many (public) proxy servers do in fact limit this to HTTPS (443) only.
+ *
+ * If you want to establish a TLS connection (such as HTTPS) between you and
+ * your destination, you may want to wrap this connector in a SecureConnector
+ * instance.
+ *
+ * Note that communication between the client and the proxy is usually via an
+ * unencrypted, plain TCP/IP HTTP connection. Note that this is the most common
+ * setup, because you can still establish a TLS connection between you and the
+ * destination host as above.
+ *
+ * If you want to connect to a (rather rare) HTTPS proxy, you may want use its
+ * HTTPS port (443) and use a SecureConnector instance to create a secure
+ * connection to the proxy.

+ *
+ * This means that you control how many operations can be executed concurrently.

+ * immediately. If you keep adding new jobs to the queue and its concurrency limit

+ * execution. Once one of the pending operations complete, it will pick the next

+/**
+ * The `Client` class is responsible for communication with the remote SOAP
+ * WebService server.
+ *
+ * It requires a [`Browser`](https://github.com/clue/reactphp-buzz#browser) object
+ * bound to the main [`EventLoop`](https://github.com/reactphp/event-loop#usage)
+ * in order to handle async requests, the WSDL file contents and an optional
+ * array of SOAP options:
+ *
+ * ```php
+ * $loop = React\EventLoop\Factory::create();
+ * $browser = new Clue\React\Buzz\Browser($loop);
+ *
+ * $wsdl = '<?xml …';
+ * $options = array();
+ *
+ * $client = new Client($browser, $wsdl, $options);
+ * ```
+ *
+ * If you need custom connector settings (DNS resolution, TLS parameters, timeouts,
+ * proxy servers etc.), you can explicitly pass a custom instance of the
+ * [`ConnectorInterface`](https://github.com/reactphp/socket#connectorinterface)
+ * to the [`Browser`](https://github.com/clue/reactphp-buzz#browser) instance:
+ *
+ * ```php
+ * $connector = new \React\Socket\Connector($loop, array(
+ *     'dns' => '127.0.0.1',
+ *     'tcp' => array(
+ *         'bindto' => '192.168.10.1:0'
+ *     ),
+ *     'tls' => array(
+ *         'verify_peer' => false,
+ *         'verify_peer_name' => false
+ *     )
+ * ));
+ *
+ * $browser = new Browser($loop, $connector);
+ * $client = new Client($browser, $wsdl);
+ * ```
+ *
+ * The `Client` works similar to PHP's `SoapClient` (which it uses under the
+ * hood), but leaves you the responsibility to load the WSDL file. This allows
+ * you to use local WSDL files, WSDL files from a cache or the most common form,
+ * downloading the WSDL file contents from an URL through the `Browser`:
+ *
+ * ```php
+ * $browser = new Browser($loop);
+ *
+ * $browser->get($url)->then(
+ *     function (ResponseInterface $response) use ($browser) {
+ *         // WSDL file is ready, create client
+ *         $client = new Client($browser, (string)$response->getBody());
+ *
+ *         // do something…
+ *     },
+ *     function (Exception $e) {
+ *         // an error occured while trying to download the WSDL
+ *     }
+ * );
+ * ```
+ *
+ * The `Client` constructor loads the given WSDL file contents into memory and
+ * parses its definition. If the given WSDL file is invalid and can not be
+ * parsed, this will throw a `SoapFault`:
+ *
+ * ```php
+ * try {
+ *     $client = new Client($browser, $wsdl);
+ * } catch (SoapFault $e) {
+ *     echo 'Error: ' . $e->getMessage() . PHP_EOL;
+ * }
+ * ```
+ *
+ * > Note that if you have `ext-xdebug` loaded, this may halt with a fatal
+ *   error instead of throwing a `SoapFault`. It is not recommended to use this
+ *   extension in production, so this should only ever affect test environments.
+ *
+ * The `Client` constructor accepts an array of options. All given options will
+ * be passed through to the underlying `SoapClient`. However, not all options
+ * make sense in this async implementation and as such may not have the desired
+ * effect. See also [`SoapClient`](http://php.net/manual/en/soapclient.soapclient.php)
+ * documentation for more details.
+ *
+ * If working in WSDL mode, the `$options` parameter is optional. If working in
+ * non-WSDL mode, the WSDL parameter must be set to `null` and the options
+ * parameter must contain the `location` and `uri` options, where `location` is
+ * the URL of the SOAP server to send the request to, and `uri` is the target
+ * namespace of the SOAP service:
+ *
+ * ```php
+ * $client = new Client($browser, null, array(
+ *     'location' => 'http://example.com',
+ *     'uri' => 'http://ping.example.com',
+ * ));
+ * ```
+ *
+ * Similarly, if working in WSDL mode, the `location` option can be used to
+ * explicitly overwrite the URL of the SOAP server to send the request to:
+ *
+ * ```php
+ * $client = new Client($browser, $wsdl, array(
+ *     'location' => 'http://example.com'
+ * ));
+ * ```
+ *
+ * You can use the `soap_version` option to change from the default SOAP 1.1 to
+ * use SOAP 1.2 instead:
+ *
+ * ```php
+ * $client = new Client($browser, $wsdl, array(
+ *     'soap_version' => SOAP_1_2
+ * ));
+ * ```
+ *
+ * You can use the `classmap` option to map certain WSDL types to PHP classes
+ * like this:
+ *
+ * ```php
+ * $client = new Client($browser, $wsdl, array(
+ *     'classmap' => array(
+ *         'getBankResponseType' => BankResponse::class
+ *     )
+ * ));
+ * ```
+ *
+ * The `proxy_host` option (and family) is not supported by this library. As an
+ * alternative, you can configure the given `$browser` instance to use an
+ * [HTTP proxy server](https://github.com/clue/reactphp-buzz#http-proxy).
+ * If you find any other option is missing or not supported here, PRs are much
+ * appreciated!
+ *
+ * All public methods of the `Client` are considered *advanced usage*.
+ * If you want to call RPC functions, see below for the [`Proxy`](#proxy) class.

+/**
+ * This class provides the implementation of a Predis connection that uses the
+ * PHP socket extension for network communication and wraps the phpiredis C
+ * extension (PHP bindings for hiredis) to parse the Redis protocol.
+ *
+ * This class is intended to provide an optional low-overhead alternative for
+ * processing responses from Redis compared to the standard pure-PHP classes.
+ * Differences in speed when dealing with short inline responses are practically
+ * nonexistent, the actual speed boost is for big multibulk responses when this
+ * protocol processor can parse and return responses very fast.
+ *
+ * For instructions on how to build and install the phpiredis extension, please
+ * consult the repository of the project.
+ *
+ * The connection parameters supported by this class are:
+ *
+ *  - scheme: it can be either 'redis', 'tcp' or 'unix'.
+ *  - host: hostname or IP address of the server.
+ *  - port: TCP port of the server.
+ *  - path: path of a UNIX domain socket when scheme is 'unix'.
+ *  - timeout: timeout to perform the connection (default is 5 seconds).
+ *  - read_write_timeout: timeout of read / write operations.

+/**
+ * This class provides the implementation of a Predis connection that uses PHP's
+ * streams for network communication and wraps the phpiredis C extension (PHP
+ * bindings for hiredis) to parse and serialize the Redis protocol.
+ *
+ * This class is intended to provide an optional low-overhead alternative for
+ * processing responses from Redis compared to the standard pure-PHP classes.
+ * Differences in speed when dealing with short inline responses are practically
+ * nonexistent, the actual speed boost is for big multibulk responses when this
+ * protocol processor can parse and return responses very fast.
+ *
+ * For instructions on how to build and install the phpiredis extension, please
+ * consult the repository of the project.
+ *
+ * The connection parameters supported by this class are:
+ *
+ *  - scheme: it can be either 'redis', 'tcp' or 'unix'.
+ *  - host: hostname or IP address of the server.
+ *  - port: TCP port of the server.
+ *  - path: path of a UNIX domain socket when scheme is 'unix'.
+ *  - timeout: timeout to perform the connection.
+ *  - read_write_timeout: timeout of read / write operations.
+ *  - async_connect: performs the connection asynchronously.
+ *  - tcp_nodelay: enables or disables Nagle's algorithm for coalescing.
+ *  - persistent: the connection is left intact after a GC collection.

+ *
+ * Some features are not yet available or they simply cannot be implemented:
+ *   - Pipelining commands.
+ *   - Publish / Subscribe.
+ *   - MULTI / EXEC transactions (not yet supported by Webdis).
+ *
+ * The connection parameters supported by this class are:
+ *
+ *  - scheme: must be 'http'.
+ *  - host: hostname or IP address of the server.
+ *  - port: TCP port of the server.
+ *  - timeout: timeout to perform the connection (default is 5 seconds).
+ *  - user: username for authentication.
+ *  - pass: password for authentication.

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

+     * 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()`).

+     * 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

+/**
+ * Process component.
+ *
+ * This class borrows logic from Symfony's Process component for ensuring
+ * compatibility when PHP is compiled with the --enable-sigchild option.
+ *
+ * This class also implements the `EventEmitterInterface`
+ * which allows you to react to certain events:
+ *
+ * exit event:
+ *     The `exit` event will be emitted whenever the process is no longer running.
+ *     Event listeners will receive the exit code and termination signal as two
+ *     arguments:
+ *
+ *     ```php
+ *     $process = new Process('sleep 10');
+ *     $process->start();
+ *
+ *     $process->on('exit', function ($code, $term) {
+ *         if ($term === null) {
+ *             echo 'exit with code ' . $code . PHP_EOL;
+ *         } else {
+ *             echo 'terminated with signal ' . $term . PHP_EOL;
+ *         }
+ *     });
+ *     ```
+ *
+ *     Note that `$code` is `null` if the process has terminated, but the exit
+ *     code could not be determined (for example
+ *     [sigchild compatibility](#sigchild-compatibility) was disabled).
+ *     Similarly, `$term` is `null` unless the process has terminated in response to
+ *     an uncaught signal sent to it.
+ *     This is not a limitation of this project, but actual how exit codes and signals
+ *     are exposed on POSIX systems, for more details see also
+ *     [here](https://unix.stackexchange.com/questions/99112/default-exit-code-when-process-is-terminated).
+ *
+ *     It's also worth noting that process termination depends on all file descriptors
+ *     being closed beforehand.
+ *     This means that all [process pipes](#stream-properties) will emit a `close`
+ *     event before the `exit` event and that no more `data` events will arrive after
+ *     the `exit` event.
+ *     Accordingly, if either of these pipes is in a paused state (`pause()` method
+ *     or internally due to a `pipe()` call), this detection may not trigger.

+     *   This is commonly a list with only a single string value, but this
+     *   technically allows multiple strings (0-255 bytes each) in a single
+     *   record. This is rarely used and depending on application you may want
+     *   to join these together or handle them separately. Each string can
+     *   transport any binary data, its character encoding is not defined (often
+     *   ASCII/UTF-8 in practice). [RFC 1464](https://tools.ietf.org/html/rfc1464)
+     *   suggests using key-value pairs such as `["name=test","version=1"]`, but
+     *   interpretation of this is not enforced and left up to consumers of this
+     *   library (used for DNS-SD/Zeroconf and others).
+     *
+     * - MX:
+     *   Mail server priority (UINT16) and target hostname without trailing dot,
+     *   for example `{"priority":10,"target":"mx.example.com"}`.
+     *   The payload data uses an associative array with fixed keys "priority"
+     *   (also commonly referred to as weight or preference) and "target" (also
+     *   referred to as exchange). If a response message contains multiple
+     *   records of this type, targets should be sorted by priority (lowest
+     *   first) - this is left up to consumers of this library (used for SMTP).
+     *
+     * - SRV:
+     *   Service priority (UINT16), service weight (UINT16), service port (UINT16)
+     *   and target hostname without trailing dot, for example
+     *   `{"priority":10,"weight":50,"port":8080,"target":"example.com"}`.
+     *   The payload data uses an associative array with fixed keys "priority",
+     *   "weight", "port" and "target" (also referred to as name).
+     *   The target may be an empty host name string if the service is decidedly
+     *   not available. If a response message contains multiple records of this
+     *   type, targets should be sorted by priority (lowest first) and selected
+     *   randomly according to their weight - this is left up to consumers of
+     *   this library, see also [RFC 2782](https://tools.ietf.org/html/rfc2782)
+     *   for more details.
+     *
+     * - SSHFP:
+     *   Includes algorithm (UNIT8), fingerprint type (UNIT8) and fingerprint
+     *   value as lower case hex string, for example:
+     *   `{"algorithm":1,"type":1,"fingerprint":"0123456789abcdef..."}`
+     *   See also https://www.iana.org/assignments/dns-sshfp-rr-parameters/dns-sshfp-rr-parameters.xhtml
+     *   for algorithm and fingerprint type assignments.
+     *
+     * - SOA:
+     *   Includes master hostname without trailing dot, responsible person email
+     *   as hostname without trailing dot and serial, refresh, retry, expire and
+     *   minimum times in seconds (UINT32 each), for example:
+     *   `{"mname":"ns.example.com","rname":"hostmaster.example.com","serial":
+     *   2018082601,"refresh":3600,"retry":1800,"expire":60000,"minimum":3600}`.
+     *
+     * - CAA:
+     *   Includes flag (UNIT8), tag string and value string, for example:
+     *   `{"flag":128,"tag":"issue","value":"letsencrypt.org"}`
+     *
+     * - OPT:
+     *   Special pseudo-type for EDNS0. Includes an array of additional opt codes
+     *   with a value according to the respective OPT code. See `Message::OPT_*`
+     *   for list of supported OPT codes. Any other OPT code not currently
+     *   supported will be an opaque binary string containing the raw data
+     *   as transported in the DNS record. For forwards compatibility, you should
+     *   not rely on this format for unknown types. Future versions may add
+     *   support for new types and this may then parse the payload data
+     *   appropriately - this will not be considered a BC break. See also
+     *   [RFC 6891](https://tools.ietf.org/html/rfc6891) for more details.
+     *
+     * - Any other unknown type:
+     *   An opaque binary string containing the RDATA as transported in the DNS
+     *   record. For forwards compatibility, you should not rely on this format
+     *   for unknown types. Future versions may add support for new types and
+     *   this may then parse the payload data appropriately - this will not be
+     *   considered a BC break. See the format definition of known types above
+     *   for more details.

+ * Send DNS queries over a TCP/IP stream transport.
+ *
+ * This is one of the main classes that send a DNS query to your DNS server.
+ *
+ * For more advanced usages one can utilize this class directly.
+ * The following example looks up the `IPv6` address for `reactphp.org`.
+ *
+ * ```php
+ * $executor = new TcpTransportExecutor('8.8.8.8:53');
+ *
+ * $executor->query(
+ *     new Query($name, Message::TYPE_AAAA, Message::CLASS_IN)

+ * }, 'printf');
+ * ```
+ *
+ * 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),

+ *     )
+ * );

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

+/**
+ * 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 that works out of the box with PHP.
+ *
+ * This event loop works out of the box on PHP 5.4 through PHP 8+ and HHVM.
+ * This means that no installation is required and this library works on all
+ * platforms and supported PHP versions.
+ * Accordingly, the [`Loop` class](#loop) and the deprecated [`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.
+ *

+/**
+ * The `React\Http\HttpServer` class is responsible for handling incoming connections and then
+ * processing each incoming HTTP request.
+ *
+ * When a complete HTTP request has been received, it will invoke the given
+ * request handler function. This request handler function needs to be passed to
+ * the constructor and will be invoked with the respective [request](#server-request)
+ * object and expects a [response](#server-response) object in return:
+ *
+ * ```php
+ * $http = new React\Http\HttpServer(function (Psr\Http\Message\ServerRequestInterface $request) {
+ *     return new React\Http\Message\Response(
+ *         React\Http\Message\Response::STATUS_OK,
+ *         array(
+ *             'Content-Type' => 'text/plain'
+ *         ),
+ *         "Hello World!\n"
+ *     );
+ * });
+ * ```
+ *
+ * Each incoming HTTP request message is always represented by the
+ * [PSR-7 `ServerRequestInterface`](https://www.php-fig.org/psr/psr-7/#321-psrhttpmessageserverrequestinterface),
+ * see also following [request](#server-request) chapter for more details.
+ *
+ * Each outgoing HTTP response message is always represented by the
+ * [PSR-7 `ResponseInterface`](https://www.php-fig.org/psr/psr-7/#33-psrhttpmessageresponseinterface),
+ * see also following [response](#server-response) chapter 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.
+ *
+ * In order to start listening for any incoming connections, the `HttpServer` needs
+ * to be attached to an instance of
+ * [`React\Socket\ServerInterface`](https://github.com/reactphp/socket#serverinterface)
+ * through the [`listen()`](#listen) method as described in the following
+ * chapter. In its most simple form, you can attach this to a
+ * [`React\Socket\SocketServer`](https://github.com/reactphp/socket#socketserver)
+ * in order to start a plaintext HTTP server like this:
+ *
+ * ```php
+ * $http = new React\Http\HttpServer($handler);
+ *
+ * $socket = new React\Socket\SocketServer('0.0.0.0:8080');
+ * $http->listen($socket);
+ * ```
+ *
+ * See also the [`listen()`](#listen) method and
+ * [hello world server example](../examples/51-server-hello-world.php)
+ * for more details.
+ *
+ * By default, the `HttpServer` buffers and parses the complete incoming HTTP
+ * request in memory. It will invoke the given request handler function when the
+ * complete request headers and request body has been received. This means the
+ * [request](#server-request) object passed to your request handler function will be
+ * fully compatible with PSR-7 (http-message). This provides sane defaults for
+ * 80% of the use cases and is the recommended way to use this library unless
+ * you're sure you know what you're doing.
+ *
+ * On the other hand, buffering complete HTTP requests in memory until they can
+ * be processed by your request handler function means that this class has to
+ * employ a number of limits to avoid consuming too much memory. In order to
+ * take the more advanced configuration out your hand, it respects setting from
+ * your [`php.ini`](https://www.php.net/manual/en/ini.core.php) to apply its
+ * default settings. This is a list of PHP settings this class respects with
+ * their respective default values:
+ *
+ * ```
+ * memory_limit 128M
+ * post_max_size 8M // capped at 64K
+ *
+ * enable_post_data_reading 1
+ * max_input_nesting_level 64
+ * max_input_vars 1000
+ *
+ * file_uploads 1
+ * upload_max_filesize 2M
+ * max_file_uploads 20
+ * ```
+ *
+ * In particular, the `post_max_size` setting limits how much memory a single
+ * HTTP request is allowed to consume while buffering its request body. This
+ * needs to be limited because the server can process a large number of requests
+ * concurrently, so the server may potentially consume a large amount of memory
+ * otherwise. To support higher concurrency by default, this value is capped
+ * at `64K`. If you assign a higher value, it will only allow `64K` by default.
+ * If a request exceeds this limit, its request body will be ignored and it will
+ * be processed like a request with no request body at all. See below for
+ * explicit configuration to override this setting.
+ *
+ * By default, this class will try to avoid consuming more than half of your
+ * `memory_limit` for buffering multiple concurrent HTTP requests. As such, with
+ * the above default settings of `128M` max, it will try to consume no more than
+ * `64M` for buffering multiple concurrent HTTP requests. As a consequence, it
+ * will limit the concurrency to `1024` HTTP requests with the above defaults.
+ *
+ * It is imperative that you assign reasonable values to your PHP ini settings.
+ * It is usually recommended to not support buffering incoming HTTP requests
+ * with a large HTTP request body (e.g. large file uploads). If you want to
+ * increase this buffer size, you will have to also increase the total memory
+ * limit to allow for more concurrent requests (set `memory_limit 512M` or more)
+ * or explicitly limit concurrency.
+ *
+ * In order to override the above buffering defaults, you can configure the
+ * `HttpServer` explicitly. You can use the
+ * [`LimitConcurrentRequestsMiddleware`](#limitconcurrentrequestsmiddleware) and
+ * [`RequestBodyBufferMiddleware`](#requestbodybuffermiddleware) (see below)
+ * to explicitly configure the total number of requests that can be handled at
+ * once like this:
+ *
+ * ```php
+ * $http = new React\Http\HttpServer(
+ *     new React\Http\Middleware\StreamingRequestMiddleware(),
+ *     new React\Http\Middleware\LimitConcurrentRequestsMiddleware(100), // 100 concurrent buffering handlers
+ *     new React\Http\Middleware\RequestBodyBufferMiddleware(2 * 1024 * 1024), // 2 MiB per request
+ *     new React\Http\Middleware\RequestBodyParserMiddleware(),
+ *     $handler
+ * ));
+ * ```
+ *
+ * In this example, we allow processing up to 100 concurrent requests at once
+ * and each request can buffer up to `2M`. This means you may have to keep a
+ * maximum of `200M` of memory for incoming request body buffers. Accordingly,
+ * you need to adjust the `memory_limit` ini setting to allow for these buffers
+ * plus your actual application logic memory requirements (think `512M` or more).
+ *
+ * > Internally, this class automatically assigns these middleware handlers
+ *   automatically when no [`StreamingRequestMiddleware`](#streamingrequestmiddleware)
+ *   is given. Accordingly, you can use this example to override all default
+ *   settings to implement custom limits.
+ *
+ * As an alternative to buffering the complete request body in memory, you can
+ * also use a streaming approach where only small chunks of data have to be kept
+ * in memory:
+ *
+ * ```php
+ * $http = new React\Http\HttpServer(
+ *     new React\Http\Middleware\StreamingRequestMiddleware(),
+ *     $handler
+ * );
+ * ```
+ *
+ * In this case, it will invoke the request handler function once the HTTP
+ * request headers have been received, i.e. before receiving the potentially
+ * much larger HTTP request body. This means the [request](#server-request) passed to
+ * your request handler function may not be fully compatible with PSR-7. This is
+ * specifically designed to help with more advanced use cases where you want to
+ * have full control over consuming the incoming HTTP request body and
+ * concurrency settings. See also [streaming incoming request](#streaming-incoming-request)
+ * below for more details.
+ *
+ * > Changelog v1.5.0: This class has been renamed to `HttpServer` from the
+ *   previous `Server` class in order to avoid any ambiguities.
+ *   The previous name has been deprecated and should not be used anymore.

+ * The internal `StreamingServer` class is responsible for handling incoming connections and then
+ * processing each incoming HTTP request.
+ *
+ * Unlike the [`HttpServer`](#httpserver) class, it does not buffer and parse the incoming
+ * HTTP request body by default. This means that the request handler will be
+ * invoked with a streaming request body. Once the request headers have been
+ * received, it will invoke the request handler function. This request handler
+ * function needs to be passed to the constructor and will be invoked with the
+ * respective [request](#request) object and expects a [response](#response)
+ * object in return:
+ *
+ * ```php
+ * $server = new StreamingServer($loop, function (ServerRequestInterface $request) {
+ *     return new Response(
+ *         Response::STATUS_OK,
+ *         array(
+ *             'Content-Type' => 'text/plain'
+ *         ),
+ *         "Hello World!\n"
+ *     );
+ * });
+ * ```
+ *
+ * Each incoming HTTP request message is always represented by the
+ * [PSR-7 `ServerRequestInterface`](https://www.php-fig.org/psr/psr-7/#321-psrhttpmessageserverrequestinterface),
+ * see also following [request](#request) chapter for more details.
+ * Each outgoing HTTP response message is always represented by the
+ * [PSR-7 `ResponseInterface`](https://www.php-fig.org/psr/psr-7/#33-psrhttpmessageresponseinterface),
+ * see also following [response](#response) chapter for more details.
+ *
+ * In order to process any connections, the server needs to be attached to an
+ * instance of `React\Socket\ServerInterface` through the [`listen()`](#listen) method
+ * as described in the following chapter. In its most simple form, you can attach
+ * this to a [`React\Socket\SocketServer`](https://github.com/reactphp/socket#socketserver)

+ * The `StreamingServer` class is considered advanced usage and unless you know

+ * more advanced use cases where you want to have full control over consuming
+ * the incoming HTTP request body and concurrency settings.
+ *
+ * In particular, this class does not buffer and parse the incoming HTTP request
+ * in memory. It will invoke the request handler function once the HTTP request
+ * headers have been received, i.e. before receiving the potentially much larger
+ * HTTP request body. This means the [request](#request) passed to your request
+ * handler function may not be fully compatible with PSR-7. See also
+ * [streaming request](#streaming-request) below for more details.

+ * Limits how many next handlers can be executed concurrently.
+ *
+ * If this middleware is invoked, it will check if the number of pending
+ * handlers is below the allowed limit and then simply invoke the next handler
+ * and it will return whatever the next handler returns (or throws).
+ *
+ * If the number of pending handlers exceeds the allowed limit, the request will
+ * be queued (and its streaming body will be paused) and it will return a pending
+ * promise.
+ * Once a pending handler returns (or throws), it will pick the oldest request
+ * from this queue and invokes the next handler (and its streaming body will be
+ * resumed).
+ *
+ * The following example shows how this middleware can be used to ensure no more
+ * than 10 handlers will be invoked at once:
+ *
+ * ```php
+ * $http = new React\Http\HttpServer(
+ *     new React\Http\Middleware\StreamingRequestMiddleware(),
+ *     new React\Http\Middleware\LimitConcurrentRequestsMiddleware(10),
+ *     $handler
+ * );
+ * ```
+ *
+ * Similarly, this middleware is often used in combination with the
+ * [`RequestBodyBufferMiddleware`](#requestbodybuffermiddleware) (see below)
+ * to limit the total number of requests that can be buffered at once:
+ *
+ * ```php
+ * $http = new React\Http\HttpServer(
+ *     new React\Http\Middleware\StreamingRequestMiddleware(),
+ *     new React\Http\Middleware\LimitConcurrentRequestsMiddleware(100), // 100 concurrent buffering handlers
+ *     new React\Http\Middleware\RequestBodyBufferMiddleware(2 * 1024 * 1024), // 2 MiB per request
+ *     new React\Http\Middleware\RequestBodyParserMiddleware(),
+ *     $handler
+ * );
+ * ```
+ *
+ * More sophisticated examples include limiting the total number of requests
+ * that can be buffered at once and then ensure the actual request handler only
+ * processes one request after another without any concurrency:
+ *
+ * ```php
+ * $http = new React\Http\HttpServer(
+ *     new React\Http\Middleware\StreamingRequestMiddleware(),
+ *     new React\Http\Middleware\LimitConcurrentRequestsMiddleware(100), // 100 concurrent buffering handlers
+ *     new React\Http\Middleware\RequestBodyBufferMiddleware(2 * 1024 * 1024), // 2 MiB per request
+ *     new React\Http\Middleware\RequestBodyParserMiddleware(),
+ *     new React\Http\Middleware\LimitConcurrentRequestsMiddleware(1), // only execute 1 handler (no concurrency)

+ *
+ * See also [streaming incoming request](../../README.md#streaming-incoming-request)
+ * for more details.
+ *
+ * Additionally, this middleware can be used in combination with the
+ * [`LimitConcurrentRequestsMiddleware`](#limitconcurrentrequestsmiddleware) and
+ * [`RequestBodyBufferMiddleware`](#requestbodybuffermiddleware) (see below)
+ * to explicitly configure the total number of requests that can be handled at
+ * once:
+ *
+ * ```php

+ *     new React\Http\Middleware\RequestBodyParserMiddleware(),
+ *     $handler
+ * );

+/**
+ * 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 ($error instanceof React\Promise\Timer\TimeoutException) {
+ *             // the operation has failed due to a timeout
+ *         } else {
+ *             // the input operation has failed due to some other error
+ *         }
+ *     }
+ * );
+ * ```
+ *
+ * Or if you're using [react/promise v3](https://github.com/reactphp/promise):
+ *
+ * ```php
+ * React\Promise\Timer\timeout($promise, 10.0)->then(function ($value) {
+ *     // the operation finished within 10.0 seconds
+ * })->catch(function (React\Promise\Timer\TimeoutException $error) {
+ *     // the operation has failed due to a timeout
+ * })->catch(function (Throwable $error) {
+ *     // the input operation has failed due to some other error
+ * });
+ * ```
+ *
+ * As discussed above, the [`timeout()`](#timeout) function will take care of
+ * the underlying operation if it takes *too long*. In this case, you can be
+ * sure the resulting promise will always be rejected with a
+ * [`TimeoutException`](#timeoutexception). On top of this, the function will
+ * try to *cancel* the underlying operation. Responsibility for this
+ * cancellation logic is left up to the underlying operation.
+ *
+ * - A common use case involves cleaning up any resources like open network
+ *   sockets or file handles or terminating external processes or timers.
+ *
+ * - If the given input `$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).

+     * 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

+     * ));
+     * ```
+     *
+     * Note that available [TLS context options],
+     * their defaults and effects of changing these may vary depending on your system
+     * and/or PHP version.
+     * Passing unknown context options has no effect.
+     *
+     * 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.
+     *
+     * 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

+ * Most higher-level components (such as a HTTP server) accept an instance

+ * implementation of this interface.
+ *
+ * Besides defining a few methods, this interface also implements the
+ * `EventEmitterInterface` which allows you to react to certain events:
+ *
+ * connection event:
+ *     The `connection` event will be emitted whenever a new connection has been
+ *     established, i.e. a new client connects to this server socket:
+ *
+ *     ```php
+ *     $socket->on('connection', function (React\Socket\ConnectionInterface $connection) {
+ *         echo 'new connection' . PHP_EOL;
+ *     });
+ *     ```
+ *
+ *     See also the `ConnectionInterface` for more details about handling the
+ *     incoming connection.
+ *
+ * error event:
+ *     The `error` event will be emitted whenever there's an error accepting a new
+ *     connection from a client.
+ *
+ *     ```php
+ *     $socket->on('error', function (Exception $e) {
+ *         echo 'error: ' . $e->getMessage() . PHP_EOL;
+ *     });
+ *     ```

+     * 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.
+     *
+     * 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.
+     *

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

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

+ *
+ * $through->write(array(2, true));
+ * ```
+ *
+ * The callback function is allowed to throw an `Exception`. In this case,
+ * the stream will emit an `error` event and then [`close()`](#close-1) the stream.
+ *
+ * ```php
+ * $through = new ThroughStream(function ($data) {

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

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