| 6.0.2 |
- Added `Swoole\Thread::yield()`, `Swoole\Thread::activeCount()`, and `Swoole\Thread::isAlive()` methods. @matyhtf - Fixed an issue where using single-thread mode and setting heartbeat in `SWOOLE_THREAD` mode would cause exceptions. @matyhtf - Fixed a segmentation fault issue after enabling `swoole.enable_fiber_mock`. @NathanFreeman - Fixed an integer overflow issue in the Redis server. @yannaingtun - The Redis server currently only supports the `RESP2` protocol. When formatting strings that do not comply with this protocol, an exception will be thrown instead of logging. @matyhtf |
| 6.0.1 |
- Fixed an issue in `SWOOLE_THREAD` mode where the process could not exit properly due to not removing the listening event. @NathanFreeman - Fixed an issue where large file uploads failed when the `single_thread` configuration was enabled. @matyhtf - Fixed an issue where compilation could not find the specific file path if the same variable was already defined in `config.m4`. @matyhtf - Fixed an issue in `Swoole\Process\Pool` where processes could not exit properly upon timeout. @matyhtf - Fixed an issue in `SWOOLE_THREAD` mode where calling `putenv` caused the program to crash. @matyhtf - Fixed an issue in `SWOOLE_THREAD` mode where event callback functions could not be set for independent ports. @matyhtf - Fixed an issue in `SWOOLE_THREAD` mode where runtime parameters could not be retrieved in events such as `onWorkerStart`. @matyhtf - Fixed an issue where Postgresql would degrade to synchronous mode when receiving large amounts of data under coroutine. @NathanFreeman - Optimized the parameter judgment logic of `swoole_substr_json_decode`/`swoole_substr_unserialize` functions. @Appla - Fixed an issue with CPU affinity settings in `config.m4`. @remicollet - In the Http service, if the process restarts, the underlying layer will send a 500 Internal Server to requests waiting in the queue, close the connection, and discard these requests after sending. @NathanFreeman - Since the runtime configuration relied upon by the `stream factory` and `stream ops` in the PHP underlying is not thread-safe, in multi-thread mode, only the main thread is allowed to modify these runtime configurations before creating child threads. @matyhtf - Fixed an issue in `SWOOLE_THREAD` mode where the heartbeat detection did not function properly. @matyhtf |
| 6.0.0 |
- Added multi-threading support, require the ZTS version of PHP. Add `--enable-swoole-thread` option to the configure command to activate it. - Added a new thread class `Swoole\Thread`. @matyhtf - Introduced thread lock `Swoole\Thread\Lock`. @matyhtf - Added thread atomic counter `Swoole\Thread\Atomic`, `Swoole\Thread\Atomic\Long`. @matyhtf - Added safe concurrent containers `Swoole\Thread\Map`, `Swoole\Thread\ArrayList`, `Swoole\Thread\Queue`. @matyhtf - The file asynchronous operation supports using `io_uring` as the underlying engine for file asynchronous operations.
