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)

    // 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)

    // 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)

    // 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)

    // 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)

    // 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)

    // 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.

    // 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)

    $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)

    // 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:

    $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)

    // 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)

    // 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)

    // 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)

    // 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)
