# Changelog
## 1.11.0 (2024-11-20)
* Feature: Improve PHP 8.4+ support by avoiding implicitly nullable types.
(#537 by @clue)
* Feature: Allow underscore character in Uri host.
(#524 by @lulhum)
* Improve test suite to fix expected error code when ext-sockets is not enabled.
(#539 by @WyriHaximus)
## 1.10.0 (2024-03-27)
* Feature: Add new PSR-7 implementation and remove dated RingCentral PSR-7 dependency.
(#518, #519, #520 and #522 by @clue)
This changeset allows us to maintain our own PSR-7 implementation and reduce
dependencies on external projects. It also improves performance slightly and
does not otherwise affect our public API. If you want to explicitly install
the old RingCentral PSR-7 dependency, you can still install it like this:
```bash
composer require ringcentral/psr7
```
* Feature: Add new `Uri` class for new PSR-7 implementation.
(#521 by @clue)
* Feature: Validate outgoing HTTP message headers and reject invalid messages.
(#523 by @clue)
* Feature: Full PHP 8.3 compatibility.
(#508 by @clue)
* Fix: Fix HTTP client to omit `Transfer-Encoding: chunked` when streaming empty request body.
(#516 by @clue)
* Fix: Ensure connection close handler is cleaned up for each request.
(#515 by @WyriHaximus)
* Update test suite and avoid unhandled promise rejections.
(#501 and #502 by @clue)
## 1.9.0 (2023-04-26)
This is a **SECURITY** and feature release for the 1.x series of ReactPHP's HTTP component.
* Security fix: This release fixes a medium severity security issue in ReactPHP's HTTP server component
that affects all versions between `v0.8.0` and `v1.8.0`. All users are encouraged to upgrade immediately.
(CVE-2023-26044 reported and fixed by @WyriHaximus)
* Feature: Support HTTP keep-alive for HTTP client (reusing persistent connections).
(#481, #484, #486 and #495 by @clue)
This feature offers significant performance improvements when sending many
requests to the same host as it avoids recreating the underlying TCP/IP
connection and repeating the TLS handshake for secure HTTPS requests.
```php
$browser = new React\Http\Browser();
// Up to 300% faster! HTTP keep-alive is enabled by default
$response = React\Async\await($browser->get('https://httpbingo.org/redirect/6'));
assert($response instanceof Psr\Http\Message\ResponseInterface);
```
* Feature: Add `Request` class to represent outgoing HTTP request message.
(#480 by @clue)
* Feature: Preserve request method and body for `307 Temporary Redirect` and `308 Permanent Redirect`.
(#442 by @dinooo13)
* Feature: Include buffer logic to avoid dependency on reactphp/promise-stream.
(#482 by @clue)
* Improve test suite and project setup and report failed assertions.
(#478 by @clue, #487 and #491 by @WyriHaximus and #475 and #479 by @SimonFrings)
## 1.8.0 (2022-09-29)
* Feature: Support for default request headers.
(#461 by @51imyy)
```php
$browser = new React\Http\Browser();
$browser = $browser->withHeader('User-Agent', 'ACME');
$browser->get($url)->then(…);
```
* Feature: Forward compatibility with upcoming Promise v3.
(#460 by @clue)
## 1.7.0 (2022-08-23)
This is a **SECURITY** and feature release for the 1.x series of ReactPHP's HTTP component.
* Security fix: This release fixes a medium severity security issue in ReactPHP's HTTP server component
that affects all versions between `v0.7.0` and `v1.6.0`. All users are encouraged to upgrade immediately.
Special thanks to Marco Squarcina (TU Wien) for reporting this and working with us to coordinate this release.
(CVE-2022-36032 reported by @lavish and fixed by @clue)
* Feature: Improve HTTP server performance by ~20%, reuse syscall values for clock time and socket addresses.
(#457 and #467 by @clue)
* Feature: Full PHP 8.2+ compatibility, refactor internal `Transaction` to avoid assigning dynamic properties.
(#459 by @clue and #466 by @WyriHaximus)
* Feature / Fix: Allow explicit `Content-Length` response header on `HEAD` requests.
(#444 by @mrsimonbennett)
* Minor documentation improvements.
(#452 by @clue, #458 by @nhedger, #448 by @jorrit and #446 by @SimonFrings)
* Improve test suite, update to use new reactphp/async package instead of clue/reactphp-block,
skip memory tests when lowering memory limit fails and fix legacy HHVM build.
(#464 and #440 by @clue and #450 by @SimonFrings)
## 1.6.0 (2022-02-03)
* Feature: Add factory methods for common HTML/JSON/plaintext/XML response types.
(#439 by @clue)
```php
$response = React\Http\Response\html("<h1>Hello wörld!</h1>\n");
$response = React\Http\Response\json(['message' => 'Hello wörld!']);
$response = React\Http\Response\plaintext("Hello wörld!\n");
$response = React\Http\Response\xml("<message>Hello wörld!</message>\n");
```
* Feature: Expose all status code constants via `Response` class.
(#432 by @clue)
```php
$response = new React\Http\Message\Response(
React\Http\Message\Response::STATUS_OK, // 200 OK
…
);
$response = new React\Http\Message\Response(
React\Http\Message\Response::STATUS_NOT_FOUND, // 404 Not Found
…
);
```
* Feature: Full support for PHP 8.1 release.
(#433 by @SimonFrings and #434 by @clue)
* Feature / Fix: Improve protocol handling for HTTP responses with no body.
(#429 and #430 by @clue)
* Internal refactoring and internal improvements for handling requests and responses.
(#422 by @WyriHaximus and #431 by @clue)
* Improve documentation, update proxy examples, include error reporting in examples.
(#420, #424, #426, and #427 by @clue)
* Update test suite to use default loop.
(#438 by @clue)
## 1.5.0 (2021-08-04)
* Feature: Update `Browser` signature to take optional `$connector` as first argument and
to match new Socket API without nullable loop arguments.
(#418 and #419 by @clue)
```php
// unchanged
$browser = new React\Http\Browser();
// deprecated
$browser = new React\Http\Browser(null, $connector);
$browser = new React\Http\Browser($loop, $connector);
// new
$browser = new React\Http\Browser($connector);
$browser = new React\Http\Browser($connector, $loop);
```
* Feature: Rename `Server` to `HttpServer` to avoid class name collisions and
to avoid any ambiguities with regards to the new `SocketServer` API.
(#417 and #419 by @clue)
```php
// deprecated
$server = new React\Http\Server($handler);
$server->listen(new React\Socket\Server(8080));
// new
$http = new React\Http\HttpServer($handler);
$http->listen(new React\Socket\SocketServer('127.0.0.1:8080'));
```
## 1.4.0 (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).
(#410 by @clue)
```php
// old (still supported)
$browser = new React\Http\Browser($loop);
$server = new React\Http\Server($loop, $handler);
// new (using default loop)
$browser = new React\Http\Browser();
$server = new React\Http\Server($handler);
```
## 1.3.0 (2021-04-11)
* Feature: Support persistent connections (`Connection: keep-alive`).
(#405 by @clue)
This shows a noticeable performance improvement especially when benchmarking
using persistent connections (which is the default pretty much everywhere).
Together with other changes in this release, this improves benchmarking
performance by around 100%.
* Feature: Require `Host` request header for HTTP/1.1 requests.
(#404 by @clue)
* Minor documentation improvements.
(#398 by @fritz-gerneth and #399 and #400 by @pavog)
* Improve test suite, use GitHub actions for continuous integration (CI).
(#402 by @SimonFrings)
## 1.2.0 (2020-12-04)
* Feature: Keep request body in memory also after consuming request body.
(#395 by @clue)
This means consumers can now always access the complete request body as
detailed in the documentation. This allows building custom parsers and more
advanced processing models without having to mess with the default parsers.
## 1.1.0 (2020-09-11)
* Feature: Support upcoming PHP 8 release, update to reactphp/socket v1.6 and adjust type checks for invalid chunk headers.
(#391 by @clue)
* Feature: Consistently resolve base URL according to HTTP specs.
(#379 by @clue)
* Feature / Fix: Expose `Transfer-Encoding: chunked` response header and fix chunked responses for `HEAD` requests.
(#381 by @clue)
* Internal refactoring to remove unneeded `MessageFactory` and `Response` classes.
(#380 and #389 by @clue)
* Minor documentation improvements and improve test suite, update to support PHPUnit 9.3.
(#385 by @clue and #393 by @SimonFrings)
## 1.0.0 (2020-07-11)
A major new feature release, see [**release announcement**](https://clue.engineering/2020/announcing-reactphp-http).
* 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.
This update involves some major new features and a number of BC breaks due to
some necessary API cleanup. We've tried hard to avoid BC breaks where possible
and minimize impact otherwise. We expect that most consumers of this package
will be affected by BC breaks, but updating should take no longer than a few
minutes. See below for more details:
* Feature: Add async HTTP client implementation.
(#368 by @clue)
```php
$browser = new React\Http\Browser($loop);
$browser->get($url)->then(function (Psr\Http\Message\ResponseInterface $response) {
echo $response->getBody();
});
```
The code has been imported as-is from [clue/reactphp-buzz v2.9.0](https://github.com/clue/reactphp-buzz),
with only minor changes to the namespace and we otherwise leave all the existing APIs unchanged.
Upgrading from [clue/reactphp-buzz v2.9.0](https://github.com/clue/reactphp-buzz)
to this release should be a matter of updating some namespace references only:
```php
// old
$browser = new Clue\React\Buzz\Browser($loop);
// new
$browser = new React\Http\Browser($loop);
```
* Feature / BC break: Add `LoopInterface` as required first constructor argument to `Server` and
change `Server` to accept variadic middleware handlers instead of `array`.
(#361 and #362 by @WyriHaximus)
```php
// old
$server = new React\Http\Server($handler);
$server = new React\Http\Server([$middleware, $handler]);
// new
$server = new React\Http\Server($loop, $handler);
$server = new React\Http\Server($loop, $middleware, $handler);
```
* Feature / BC break: Move `Response` class to `React\Http\Message\Response` and
expose `ServerRequest` class to `React\Http\Message\ServerRequest`.
(#370 by @clue)
```php
// old
$response = new React\Http\Response(200, [], 'Hello!');
// new
$response = new React\Http\Message\Response(200, [], 'Hello!');
```
* Feature / BC break: Add `StreamingRequestMiddleware` to stream incoming requests, mark `StreamingServer` as internal.
(#367 by @clue)
```php
// old: advanced StreamingServer is now internal only
$server = new React\Http\StreamingServer($handler);
// new: use StreamingRequestMiddleware instead of StreamingServer
$server = new React\Http\Server(
$loop,
new React\Http\Middleware\StreamingRequestMiddleware(),
$handler
);
```
* Feature / BC break: Improve default concurrency to 1024 requests and cap default request buffer at 64K.
(#371 by @clue)
This improves default concurrency to 1024 requests and caps the default request buffer at 64K.
The previous defaults resulted in just 4 concurrent requests with a request buffer of 8M.
See [`Server`](README.md#server) for details on how to override these defaults.
* Feature: Expose ReactPHP in `User-Agent` client-side request header and in `Server` server-side response header.
(#374 by @clue)
* Mark all classes as `final` to discourage inheriting from it.
(#373 by @WyriHaximus)
* Improve documentation and use fully-qualified class names throughout the documentation and
add ReactPHP core team as authors to `composer.json` and license file.
(#366 and #369 by @WyriHaximus and #375 by @clue)
* Improve test suite and support skipping all online tests with `--exclude-group internet`.
(#372 by @clue)
## 0.8.7 (2020-07-05)
* Fix: Fix parsing multipart request body with quoted header parameters (dot net).
(#363 by @ebimmel)
* Fix: Fix calculating concurrency when `post_max_size` ini is unlimited.
(#365 by @clue)
* Improve test suite to run tests on PHPUnit 9 and clean up test suite.
(#364 by @SimonFrings)
## 0.8.6 (2020-01-12)
* Fix: Fix parsing `Cookie` request header with comma in its values.
(#352 by @fiskie)
* Fix: Avoid unneeded warning when decoding invalid data on PHP 7.4.
(#357 by @WyriHaximus)
* Add .gitattributes to exclude dev files from exports.
(#353 by @reedy)
## 0.8.5 (2019-10-29)
* Internal refactorings and optimizations to improve request parsing performance.
Benchmarks suggest number of requests/s improved by ~30% for common `GET` requests.
(#345, #346, #349 and #350 by @clue)
* Add documentation and example for JSON/XML request body and
improve documentation for concurrency and streaming requests and for error handling.
(#341 and #342 by @clue)
## 0.8.4 (2019-01-16)
* Improvement: Internal refactoring to simplify response header logic.
(#321 by @clue)
* Improvement: Assign Content-Length response header automatically only when size is known.
(#329 by @clue)
* Improvement: Import global functions for better performance.
(#330 by @WyriHaximus)
## 0.8.3 (2018-04-11)
* Feature: Do not pause connection stream to detect closed connections immediately.
(#315 by @clue)
* Feature: Keep incoming `Transfer-Encoding: chunked` request header.
(#316 by @clue)
* Feature: Reject invalid requests that contain both `Content-Length` and `Transfer-Encoding` request headers.
(#318 by @clue)
* Minor internal refactoring to simplify connection close logic after sending response.
(#317 by @clue)
## 0.8.2 (2018-04-06)
* Fix: Do not pass `$next` handler to final request handler.
(#308 by @clue)
* Fix: Fix awaiting queued handlers when cancelling a queued handler.
(#313 by @clue)
* Fix: Fix Server to skip `SERVER_ADDR` params for Unix domain sockets (UDS).
(#307 by @clue)
* Documentation for PSR-15 middleware and minor documentation improvements.
(#314 by @clue and #297, #298 and #310 by @seregazhuk)
* Minor code improvements and micro optimizations.
(#301 by @seregazhuk and #305 by @kalessil)
## 0.8.1 (2018-01-05)
* Major request handler performance improvement. Benchmarks suggest number of
requests/s improved by more than 50% for common `GET` requests!
We now avoid queuing, buffering and wrapping incoming requests in promises
when we're below limits and instead can directly process common requests.
(#291, #292, #293, #294 and #296 by @clue)
* Fix: Fix concurrent invoking next middleware request handlers
(#293 by @clue)
* Small code improvements
(#286 by @seregazhuk)
* Improve test suite to be less fragile when using `ext-event` and
fix test suite forward compatibility with upcoming EventLoop releases
(#288 and #290 by @clue)
## 0.8.0 (2017-12-12)
* Feature / BC break: Add new `Server` facade that buffers and parses incoming
HTTP requests. This provides full PSR-7 compatibility, including support for
form submissions with POST fields and file uploads.
The old `Server` has been renamed to `StreamingServer` for advanced usage
and is used internally.
(#266, #271, #281, #282, #283 and #284 by @WyriHaximus and @clue)
```php
// old: handle incomplete/streaming requests
$server = new Server($handler);
// new: handle complete, buffered and parsed requests
// new: full PSR-7 support, including POST fields and file uploads
$server = new Server($handler);
// new: handle incomplete/streaming requests
$server = new StreamingServer($handler);
```
> While this is technically a small BC break, this should in fact not break
most consuming code. If you rely on the old request streaming, you can
explicitly use the advanced `StreamingServer` to restore old behavior.
* Feature: Add support for middleware request handler arrays
(#215, #228, #229, #236, #237, #238, #246, #247, #277, #279 and #285 by @WyriHaximus, @clue and @jsor)
```php
// new: middleware request handler arrays
$server = new Server(array(
function (ServerRequestInterface $request, callable $next) {
$request = $request->withHeader('Processed', time());
return $next($request);
},
function (ServerRequestInterface $request) {
return new Response();
}
));
```
* Feature: Add support for limiting how many next request handlers can be
executed concurrently (`LimitConcurrentRequestsMiddleware`)
(#272 by @clue and @WyriHaximus)
```php
// new: explicitly limit concurrency
$server = new Server(array(
new LimitConcurrentRequestsMiddleware(10),
$handler
));
```
* Feature: Add support for buffering the incoming request body
(`RequestBodyBufferMiddleware`).
This feature mimics PHP's default behavior and respects its `post_max_size`
ini setting by default and allows explicit configuration.
(#216, #224, #263, #276 and #278 by @WyriHaximus and #235 by @andig)
```php
// new: buffer up to 10 requests with 8 MiB each
$server = new StreamingServer(array(
new LimitConcurrentRequestsMiddleware(10),
new RequestBodyBufferMiddleware('8M'),
$handler
));
```
* Feature: Add support for parsing form submissions with POST fields and file
uploads (`RequestBodyParserMiddleware`).
This feature mimics PHP's default behavior and respects its ini settings and
`MAX_FILE_SIZE` POST fields by default and allows explicit configuration.
(#220, #226, #252, #261, #264, #265, #267, #268, #274 by @WyriHaximus and @clue)
```php
// new: buffer up to 10 requests with 8 MiB each
// and limit to 4 uploads with 2 MiB each
$server = new StreamingServer(array(
new LimitConcurrentRequestsMiddleware(10),
new RequestBodyBufferMiddleware('8M'),
new RequestBodyParserMiddleware('2M', 4)
$handler
));
```
* Feature: Update Socket to work around sending secure HTTPS responses with PHP < 7.1.4
(#244 by @clue)
* Feature: Support sending same response header multiple times (e.g. `Set-Cookie`)
(#248 by @clue)
* Feature: Raise maximum request header size to 8k to match common implementations
(#253 by @clue)
* Improve test suite by adding forward compatibility with PHPUnit 6, test
against PHP 7.1 and PHP 7.2 and refactor and remove risky and duplicate tests.
(#243, #269 and #270 by @carusogabriel and #249 by @clue)
* Minor code refactoring to move internal classes to `React\Http\Io` namespace
and clean up minor code and documentation issues
(#251 by @clue, #227 by @kalessil, #240 by @christoph-kluge, #230 by @jsor and #280 by @andig)
## 0.7.4 (2017-08-16)
* Improvement: Target evenement 3.0 a long side 2.0 and 1.0
(#212 by @WyriHaximus)
## 0.7.3 (2017-08-14)
* Feature: Support `Throwable` when setting previous exception from server callback
(#155 by @jsor)
* Fix: Fixed URI parsing for origin-form requests that contain scheme separator
such as `/path?param=http://example.com`.
(#209 by @aaronbonneau)
* Improve test suite by locking Travis distro so new defaults will not break the build
(#211 by @clue)
## 0.7.2 (2017-07-04)
* Fix: Stricter check for invalid request-line in HTTP requests
(#206 by @clue)
* Refactor to use HTTP response reason phrases from response object
(#205 by @clue)
## 0.7.1 (2017-06-17)
* Fix: Fix parsing CONNECT request without `Host` header
(#201 by @clue)
* Internal preparation for future PSR-7 `UploadedFileInterface`
(#199 by @WyriHaximus)
## 0.7.0 (2017-05-29)
* Feature / BC break: Use PSR-7 (http-message) standard and
`Request-In-Response-Out`-style request handler callback.
Pass standard PSR-7 `ServerRequestInterface` and expect any standard
PSR-7 `ResponseInterface` in return for the request handler callback.
(#146 and #152 and #170 by @legionth)
```php
// old
$app = function (Request $request, Response $response) {
$response->writeHead(200, array('Content-Type' => 'text/plain'));
$response->end("Hello world!\n");
};
// new
$app = function (ServerRequestInterface $request) {
return new Response(
200,
array('Content-Type' => 'text/plain'),
"Hello world!\n"
);
};
```
A `Content-Length` header will automatically be included if the size can be
determined from the response body.
(#164 by @maciejmrozinski)
The request handler callback will automatically make sure that responses to
HEAD requests and certain status codes, such as `204` (No Content), never
contain a response body.
(#156 by @clue)
The intermediary `100 Continue` response will automatically be sent if
demanded by a HTTP/1.1 client.
(#144 by @legionth)
The request handler callback can now return a standard `Promise` if
processing the request needs some time, such as when querying a database.
Similarly, the request handler may return a streaming response if the
response body comes from a `ReadableStreamInterface` or its size is
unknown in advance.
```php
// old
$app = function (Request $request, Response $response) use ($db) {
$db->query()->then(function ($result) use ($response) {
$response->writeHead(200, array('Content-Type' => 'text/plain'));
$response->end($result);
});
};
// new
$app = function (ServerRequestInterface $request) use ($db) {
return $db->query()->then(function ($result) {
return new Response(
200,
array('Content-Type' => 'text/plain'),
$result
);
});
};
```
Pending promies and response streams will automatically be canceled once the
client connection closes.
(#187 and #188 by @clue)
The `ServerRequestInterface` contains the full effective request URI,
server-side parameters, query parameters and parsed cookies values as
defined in PSR-7.
(#167 by @clue and #174, #175 and #180 by @legionth)
```php
$app = function (ServerRequestInterface $request) {
return new Response(
200,
array('Content-Type' => 'text/plain'),
$request->getUri()->getScheme()
);
};
```
Advanced: Support duplex stream response for `Upgrade` requests such as
`Upgrade: WebSocket` or custom protocols and `CONNECT` requests
(#189 and #190 by @clue)
> Note that the request body will currently not be buffered and parsed by
default, which depending on your particilar use-case, may limit
interoperability with the PSR-7 (http-message) ecosystem.
The provided streaming request body interfaces allow you to perform
buffering and parsing as needed in the request handler callback.
See also the README and examples for more details.
* Feature / BC break: Replace `request` listener with callback function and
use `listen()` method to support multiple listening sockets
(#97 by @legionth and #193 by @clue)
```php
// old
$server = new Server($socket);
$server->on('request', $app);
// new
$server = new Server($app);
$server->listen($socket);
```
* Feature: Support the more advanced HTTP requests, such as
`OPTIONS * HTTP/1.1` (`OPTIONS` method in asterisk-form),
`GET http://example.com/path HTTP/1.1` (plain proxy requests in absolute-form),
`CONNECT example.com:443 HTTP/1.1` (`CONNECT` proxy requests in authority-form)
and sanitize `Host` header value across all requests.
(#157, #158, #161, #165, #169 and #173 by @clue)
* Feature: Forward compatibility with Socket v1.0, v0.8, v0.7 and v0.6 and
forward compatibility with Stream v1.0 and v0.7
(#154, #163, #183, #184 and #191 by @clue)
* Feature: Simplify examples to ease getting started and
add benchmarking example
(#151 and #162 by @clue)
* Improve test suite by adding tests for case insensitive chunked transfer
encoding and ignoring HHVM test failures until Travis tests work again.
(#150 by @legionth and #185 by @clue)
## 0.6.0 (2017-03-09)
* Feature / BC break: The `Request` and `Response` objects now follow strict
stream semantics and their respective methods and events.
(#116, #129, #133, #135, #136, #137, #138, #140, #141 by @legionth
and #122, #123, #130, #131, #132, #142 by @clue)
This implies that the `Server` now supports proper detection of the request
message body stream, such as supporting decoding chunked transfer encoding,
delimiting requests with an explicit `Content-Length` header
and those with an empty request message body.
These streaming semantics are compatible with previous Stream v0.5, future
compatible with v0.5 and upcoming v0.6 versions and can be used like this:
```php
$http->on('request', function (Request $request, Response $response) {
$contentLength = 0;
$request->on('data', function ($data) use (&$contentLength) {
$contentLength += strlen($data);
});
$request->on('end', function () use ($response, &$contentLength){
$response->writeHead(200, array('Content-Type' => 'text/plain'));
$response->end("The length of the submitted request body is: " . $contentLength);
});
// an error occured
// e.g. on invalid chunked encoded data or an unexpected 'end' event
$request->on('error', function (\Exception $exception) use ($response, &$contentLength) {
$response->writeHead(400, array('Content-Type' => 'text/plain'));
$response->end("An error occured while reading at length: " . $contentLength);
});
});
```
Similarly, the `Request` and `Response` now strictly follow the
`close()` method and `close` event semantics.
Closing the `Request` does not interrupt the underlying TCP/IP in
order to allow still sending back a valid response message.
Closing the `Response` does terminate the underlying TCP/IP
connection in order to clean up resources.
You should make sure to always attach a `request` event listener
like above. The `Server` will not respond to an incoming HTTP
request otherwise and keep the TCP/IP connection pending until the
other side chooses to close the connection.
* Feature: Support `HTTP/1.1` and `HTTP/1.0` for `Request` and `Response`.
(#124, #125, #126, #127, #128 by @clue and #139 by @legionth)
The outgoing `Response` will automatically use the same HTTP version as the
incoming `Request` message and will only apply `HTTP/1.1` semantics if
applicable. This includes that the `Response` will automatically attach a
`Date` and `Connection: close` header if applicable.
This implies that the `Server` now automatically responds with HTTP error
messages for invalid requests (status 400) and those exceeding internal
request header limits (status 431).
## 0.5.0 (2017-02-16)
* Feature / BC break: Change `Request` methods to be in line with PSR-7
(#117 by @clue)
* Rename `getQuery()` to `getQueryParams()`
* Rename `getHttpVersion()` to `getProtocolVersion()`
* Change `getHeaders()` to always return an array of string values
for each header
* Feature / BC break: Update Socket component to v0.5 and
add secure HTTPS server support
(#90 and #119 by @clue)
```php
// old plaintext HTTP server
$socket = new React\Socket\Server($loop);
$socket->listen(8080, '127.0.0.1');
$http = new React\Http\Server($socket);
// new plaintext HTTP server
$socket = new React\Socket\Server('127.0.0.1:8080', $loop);
$http = new React\Http\Server($socket);
// new secure HTTPS server
$socket = new React\Socket\Server('127.0.0.1:8080', $loop);
$socket = new React\Socket\SecureServer($socket, $loop, array(
'local_cert' => __DIR__ . '/localhost.pem'
));
$http = new React\Http\Server($socket);
```
* BC break: Mark internal APIs as internal or private and
remove unneeded `ServerInterface`
(#118 by @clue, #95 by @legionth)
## 0.4.4 (2017-02-13)
* Feature: Add request header accessors (à la PSR-7)
(#103 by @clue)
```php
// get value of host header
$host = $request->getHeaderLine('Host');
// get list of all cookie headers
$cookies = $request->getHeader('Cookie');
```
* Feature: Forward `pause()` and `resume()` from `Request` to underlying connection
(#110 by @clue)
```php
// support back-pressure when piping request into slower destination
$request->pipe($dest);
// manually pause/resume request
$request->pause();
$request->resume();
```
* Fix: Fix `100-continue` to be handled case-insensitive and ignore it for HTTP/1.0.
Similarly, outgoing response headers are now handled case-insensitive, e.g
we no longer apply chunked transfer encoding with mixed-case `Content-Length`.
(#107 by @clue)
```php
// now handled case-insensitive
$request->expectsContinue();
// now works just like properly-cased header
$response->writeHead($status, array('content-length' => 0));
```
* Fix: Do not emit empty `data` events and ignore empty writes in order to
not mess up chunked transfer encoding
(#108 and #112 by @clue)
* Lock and test minimum required dependency versions and support PHPUnit v5
(#113, #115 and #114 by @andig)
## 0.4.3 (2017-02-10)

(#83 by @nick4fake)
* First class support for PHP 5.3 through PHP 7 and HHVM
(#101 and #102 by @clue, #66 by @WyriHaximus)
* Improve test suite by adding PHPUnit to require-dev,
improving forward compatibility with newer PHPUnit versions
and replacing unneeded test stubs
