Feature: Forward compatibility with react/promise 3. (#214 by @WyriHaximus and @clue)
Feature: Full support for PHP 8.2 release. (#298 by @WyriHaximus)
Feature: Avoid unneeded syscall on socket close. (#292 by @clue)
Feature / Fix: Improve error reporting when custom error handler is used. (#290 by @clue)
Fix: Fix invalid references in exception stack trace. (#284 by @clue)
Minor documentation improvements, update to use new reactphp/async package instead of clue/reactphp-block. (#296 by @clue, #285 by @SimonFrings and #295 by @nhedger)
Improve test suite, update macOS and HHVM environment, fix optional tests for ENETUNREACH
.
(#288, #289 and #297 by @clue)
Improve test suite to skip FD test when hitting memory limit and skip legacy TLS 1.0 tests if disabled by system. (#278 and #281 by @clue and #283 by @SimonFrings)
Feature: Support listening on existing file descriptors (FDs) with SocketServer
.
(#269 by @clue)
$socket = new React\Socket\SocketSever('php://fd/3');
This is particularly useful when using systemd socket activation like this:
$ systemd-socket-activate -l 8000 php examples/03-http-server.php php://fd/3
Feature: Improve error messages for failed connection attempts with errno
and errstr
.
(#265, #266, #267, #270 and #271 by @clue and #268 by @SimonFrings)
All error messages now always include the appropriate errno
and errstr
to
give more details about the error reason when available. Along with these
error details exposed by the underlying system functions, it will also
include the appropriate error constant name (such as ECONNREFUSED
) when
available. Accordingly, failed TCP/IP connections will now report the actual
underlying error condition instead of a generic "Connection refused" error.
Higher-level error messages will now consistently report the connection URI
scheme and hostname used in all error messages.
For most common use cases this means that simply reporting the Exception
message should give the most relevant details for any connection issues:
$connector = new React\Socket\Connector();
$connector->connect($uri)->then(function (React\Socket\ConnectionInterface $conn) {
// …
}, function (Exception $e) {
echo 'Error:' . $e->getMessage() . PHP_EOL;
});
The new SocketServer
class has been added with an improved constructor signature
as a replacement for the previous Server
class in order to avoid any ambiguities.
The previous name has been deprecated and should not be used anymore.
In its most basic form, the deprecated Server
can now be considered an alias for new SocketServer
.
// deprecated
$socket = new React\Socket\Server(0);
$socket = new React\Socket\Server('127.0.0.1:8000');
$socket = new React\Socket\Server('127.0.0.1:8000', null, $context);
$socket = new React\Socket\Server('127.0.0.1:8000', $loop, $context);
// new
$socket = new React\Socket\SocketServer('127.0.0.1:0');
$socket = new React\Socket\SocketServer('127.0.0.1:8000');
$socket = new React\Socket\SocketServer('127.0.0.1:8000', $context);
$socket = new React\Socket\SocketServer('127.0.0.1:8000', $context, $loop);
Feature: Update Connector
signature to take optional $context
as first argument.
(#264 by @clue)
The new signature has been added to match the new SocketServer
and
consistently move the now commonly unneeded loop argument to the last argument.
The previous signature has been deprecated and should not be used anymore.
In its most basic form, both signatures are compatible.
// deprecated
$connector = new React\Socket\Connector(null, $context);
$connector = new React\Socket\Connector($loop, $context);
// new
$connector = new React\Socket\Connector($context);
$connector = new React\Socket\Connector($context, $loop);
A major new feature release, see release announcement.
// old (still supported)
$socket = new React\Socket\Server('127.0.0.1:8080', $loop);
$connector = new React\Socket\Connector($loop);
// new (using default loop)
$socket = new React\Socket\Server('127.0.0.1:8080');
$connector = new React\Socket\Connector();
Feature: Support falling back to multiple DNS servers from DNS config. (#257 by @clue)
If you're using the default Connector
, it will now use all DNS servers
configured on your system. If you have multiple DNS servers configured and
connectivity to the primary DNS server is broken, it will now fall back to
your other DNS servers, thus providing improved connectivity and redundancy
for broken DNS configurations.
Feature: Use round robin for happy eyeballs DNS responses (load balancing). (#247 by @clue)
If you're using the default Connector
, it will now randomize the order of
the IP addresses resolved via DNS when connecting. This allows the load to
be distributed more evenly across all returned IP addresses. This can be
used as a very basic DNS load balancing mechanism.
Internal improvement to avoid unhandled rejection for future Promise API. (#258 by @clue)
Improve test suite, use GitHub actions for continuous integration (CI). (#254 by @SimonFrings)
Feature: Change default socket backlog size to 511. (#242 by @clue)
Fix: Fix closing connection when cancelling during TLS handshake. (#241 by @clue)
Fix: Fix blocking during possible accept()
race condition
when multiple socket servers listen on same socket address.
(#244 by @clue)
Improve test suite, update PHPUnit config and add full core team to the license. (#243 by @SimonFrings and #245 by @WyriHaximus)
Feature / Fix: Improve error handling and reporting for happy eyeballs and immediately try next connection when one connection attempt fails. (#230, #231, #232 and #233 by @clue)
Error messages for failed connection attempts now include more details to ease debugging. Additionally, the happy eyeballs algorithm has been improved to avoid having to wait for some timers to expire which significantly improves connection setup times (in particular when IPv6 isn't available).
Improve test suite, minor code cleanup and improve code coverage to 100%. Update to PHPUnit 9 and skip legacy TLS 1.0 / TLS 1.1 tests if disabled by system. Run tests on Windows and simplify Travis CI test matrix for Mac OS X setup and skip all TLS tests on legacy HHVM. (#229, #235, #236 and #238 by @clue and #239 by @SimonFrings)
A major new feature release, see release announcement.
Feature: Add IPv6 support to Connector
(implement "Happy Eyeballs" algorithm to support IPv6 probing).
IPv6 support is turned on by default, use new happy_eyeballs
option in Connector
to toggle behavior.
(#196, #224 and #225 by @WyriHaximus and @clue)
Feature: Default to using DNS cache (with max 256 entries) for Connector
.
(#226 by @clue)
Add .gitattributes
to exclude dev files from exports and some minor code style fixes.
(#219 by @reedy and #218 by @mmoreram)
Improve test suite to fix failing test cases when using new DNS component, significantly improve test performance by awaiting events instead of sleeping, exclude TLS 1.3 test on PHP 7.3, run tests on PHP 7.4 and simplify test matrix. (#208, #209, #210, #217 and #223 by @clue)
Avoid uneeded fragmented TLS work around for PHP 7.3.3+ and work around failing test case detecting EOF on TLS 1.3 socket streams. (#201 and #202 by @clue)
Feature / Fix: Improve TLS 1.3 support. (#186 by @clue)
TLS 1.3 is now an official standard as of August 2018! :tada: The protocol has major improvements in the areas of security, performance, and privacy. TLS 1.3 is supported by default as of OpenSSL 1.1.1. For example, this version ships with Ubuntu 18.10 (and newer) by default, meaning that recent installations support TLS 1.3 out of the box :shipit:
Fix: Avoid possibility of missing remote address when TLS handshake fails. (#188 by @clue)
Improve performance by prefixing all global functions calls with \
to skip the look up and resolve process and go straight to the global function.
(#183 by @WyriHaximus)
Update documentation to use full class names with namespaces. (#187 by @clue)
Improve test suite to avoid some possible race conditions,
test against PHP 7.3 on Travis and
use dedicated assertInstanceOf()
assertions.
(#185 by @clue, #178 by @WyriHaximus and #181 by @carusogabriel)
Feature: Improve error reporting for failed connection attempts and improve cancellation forwarding during DNS lookup, TCP/IP connection or TLS handshake. (#168, #169, #170, #171, #176 and #177 by @clue)
All error messages now always contain a reference to the remote URI to give more details which connection actually failed and the reason for this error. Accordingly, failures during DNS lookup will now mention both the remote URI as well as the DNS error reason. TCP/IP connection issues and errors during a secure TLS handshake will both mention the remote URI as well as the underlying socket error. Similarly, lost/dropped connections during a TLS handshake will now report a lost connection instead of an empty error reason.
For most common use cases this means that simply reporting the Exception
message should give the most relevant details for any connection issues:
$promise = $connector->connect('tls://example.com:443');
$promise->then(function (ConnectionInterface $conn) use ($loop) {
// …
}, function (Exception $e) {
echo $e->getMessage();
});
Contains no other changes, so it's actually fully compatible with the v0.8.12 release.
Feature: Improve memory consumption for failed and cancelled connection attempts. (#161 by @clue)
Improve test suite to fix Travis config to test against legacy PHP 5.3 again. (#162 by @clue)
/etc/resolv.conf
on Unix/Linux/Mac/Docker/WSL and WMIC on Windows)
(#152 by @clue)This means that connecting to hosts that are managed by a local DNS server, such as a corporate DNS server or when using Docker containers, will now work as expected across all platforms with no changes required:
$connector = new Connector($loop);
$connector->connect('intranet.example:80')->then(function ($connection) {
// …
});
Feature: Support explicitly choosing TLS version to negotiate with remote side
by respecting crypto_method
context parameter for all classes.
(#149 by @clue)
By default, all connector and server classes support TLSv1.0+ and exclude support for legacy SSLv2/SSLv3. As of PHP 5.6+ you can also explicitly choose the TLS version you want to negotiate with the remote side:
// new: now supports 'crypto_method` context parameter for all classes
$connector = new Connector($loop, array(
'tls' => array(
'crypto_method' => STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT
)
));
This fixes the root cause of an uncaught Exception
that only manifested
itself after the recent Stream v0.7.4 component update and only if you're
using ext-event
(ExtEventLoop
).
Server
with unix://
URI scheme
and add advanced UnixServer
class.
(#120 by @andig)// new: Server now supports "unix://" scheme
$server = new Server('unix:///tmp/server.sock', $loop);
// new: advanced usage
$server = new UnixServer('/tmp/server.sock', $loop);
Restructure examples to ease getting started (#136 by @clue)
Improve test suite by adding forward compatibility with PHPUnit 6 and ignore Mac OS X test failures for now until Travis tests work again (#133 by @gabriel-caruso and #134 by @clue)
Fix: Work around PHP bug with Unix domain socket (UDS) paths for Mac OS X (#123 by @andig)
Fix: Fix SecureServer
to return null
URI if server socket is already closed
(#129 by @clue)
Improve test suite by adding forward compatibility with PHPUnit v5 and forward compatibility with upcoming EventLoop releases in tests and test Mac OS X on Travis (#122 by @andig and #125, #127 and #130 by @clue)
Feature: Add FixedUriConnector
decorator to use fixed, preconfigured URI instead
(#117 by @clue)
This can be useful for consumers that do not support certain URIs, such as when you want to explicitly connect to a Unix domain socket (UDS) path instead of connecting to a default address assumed by an higher-level API:
$connector = new FixedUriConnector(
'unix:///var/run/docker.sock',
new UnixConnector($loop)
);
// destination will be ignored, actually connects to Unix domain socket
$promise = $connector->connect('localhost:80');
Feature: Reduce memory consumption for failed connections (#113 by @valga)
Fix: Work around write chunk size for TLS streams for PHP < 7.1.14 (#114 by @clue)
This means that connecting to hosts such as localhost
will now work as
expected across all platforms with no changes required:
$connector = new Connector($loop);
$connector->connect('localhost:8080')->then(function ($connection) {
// …
});
Feature: Forward compatibility with upcoming EventLoop v1.0 and v0.5 and target evenement 3.0 a long side 2.0 and 1.0 (#104 by @clue and #111 by @WyriHaximus)
Improve test suite by locking Travis distro so new defaults will not break the build and fix HHVM build for now again and ignore future HHVM build errors (#109 and #110 by @clue)
Minor documentation fixes (#103 by @christiaan and #108 by @hansott)
Server
class now acts as a facade for existing server classes
and renamed old Server
to TcpServer
for advanced usage.
(#96 and #97 by @clue)The Server
class is now the main class in this package that implements the
ServerInterface
and allows you to accept incoming streaming connections,
such as plaintext TCP/IP or secure TLS connection streams.
This is not a BC break and consumer code does not have to be updated.
- $parts = parse_url('tcp://' . $conn->getRemoteAddress());
+ $parts = parse_url($conn->getRemoteAddress());
Fix: Fix unix://
addresses for Unix domain socket (UDS) paths
(#100 by @clue)
Feature: Forward compatibility with Stream v1.0 and v0.7 (#99 by @clue)
This means that this package now provides async, streaming plaintext TCP/IP and secure TLS socket server and client connections for ReactPHP.
$connector = new React\Socket\Connector($loop);
$connector->connect('google.com:80')->then(function (ConnectionInterface $conn) {
$connection->write('…');
});
Accordingly, the ConnectionInterface
is now used to represent both incoming
server side connections as well as outgoing client side connections.
If you've previously used the SocketClient component to establish outgoing
client connections, upgrading should take no longer than a few minutes.
All classes have been merged as-is from the latest v0.7.0
release with no
other changes, so you can simply update your code to use the updated namespace
like this:
// old from SocketClient component and namespace
$connector = new React\SocketClient\Connector($loop);
$connector->connect('google.com:80')->then(function (ConnectionInterface $conn) {
$connection->write('…');
});
// new
$connector = new React\Socket\Connector($loop);
$connector->connect('google.com:80')->then(function (ConnectionInterface $conn) {
$connection->write('…');
});
$server = new Server(0, $loop);
$server = new LimitingServer($server, 100);
$server->on('connection', function (ConnectionInterface $connection) {
$connection->write('hello there!' . PHP_EOL);
…
});
$server = new Server(0, $loop);
$server->pause();
$loop->addTimer(1.0, function() use ($server) {
$server->resume();
});
listen()
call with URIs passed to constructor
and reject listening on hostnames with InvalidArgumentException
and replace ConnectionException
with RuntimeException
for consistency
(#61, #66 and #72 by @clue) // old
$server = new Server($loop);
$server->listen(8080);
// new
$server = new Server(8080, $loop);
Similarly, you can now pass a full listening URI to the constructor to change the listening host:
// old
$server = new Server($loop);
$server->listen(8080, '127.0.0.1');
// new
$server = new Server('127.0.0.1:8080', $loop);
Trying to start listening on (DNS) host names will now throw an
InvalidArgumentException
, use IP addresses instead:
// old
$server = new Server($loop);
$server->listen(8080, 'localhost');
// new
$server = new Server('127.0.0.1:8080', $loop);
If trying to listen fails (such as if port is already in use or port below
1024 may require root access etc.), it will now throw a RuntimeException
,
the ConnectionException
class has been removed:
// old: throws React\Socket\ConnectionException
$server = new Server($loop);
$server->listen(80);
// new: throws RuntimeException
$server = new Server(80, $loop);
// old
$server->shutdown();
// new
$server->close();
// old
echo $server->getPort(); // 8080
// new
echo $server->getAddress(); // 127.0.0.1:8080
// old
echo $connection->getRemoteAddress(); // 192.168.0.1
// new
echo $connection->getRemoteAddress(); // 192.168.0.1:51743
echo $connection->getLocalAddress(); // 127.0.0.1:8080
Server
and SecureServer
class are now marked final
and you can no longer extend
them
(which was never documented or recommended anyway).
Public properties and event handlers are now internal only.
Please use composition instead of extension.
