swoole: Changelog

Version Message
6.0.0 - Swoole supports multi-threading mode. When PHP is in ZTS mode and Swoole is compiled with --enable-swoole-thread, the multi-threading mode can be utilized.
- Added a new thread management class Swoole\Thread.
- Introduced thread lock Swoole\Thread\Lock.
- Added thread atomic counter Swoole\Thread\Atomic, Swoole\Thread\Atomic\Long.
- Added safe concurrent containers Swoole\Thread\Map, Swoole\Thread\ArrayList, Swoole\Thread\Queue.
- File asynchronous operations support iouring as the underlying engine. Installing liburing and compiling Swoole with --enable-iouring enables asynchronous operations for functions like file_get_contents, file_put_contents, fopen, fclose, fread, fwrite, mkdir, unlink, fsync, fdatasync, rename, fstat, lstat, filesize through iouring.
- Upgraded Boost Context to version 1.84. Now, Loongson CPUs can also supports coroutines.
- Fixed the issue where installation via pecl was not possible.
- Fixed the bug where setting keepalive was not possible for Swoole\Coroutine\FastCGI\Client.
- Fixed the issue where exceeding the max_input_vars would throw an error, causing the process to restart repeatedly.
- Fixed unknown issues caused by using Swoole\Event::wait() within a coroutine.
- Fixed the problem where proc_open does not support pty in coroutine mode.
- Fixed segmentation fault issues with pdo_sqlite on PHP 8.3.
- Fixed unnecessary warnings during the compilation of Swoole.
- Fixed the error thrown by zend_fetch_resource2_ex when STDOUT/STDERR are already closed.
- Fixed ineffective set_tcp_nodelay configuration.
- Fixed the occasional unreachable branch issue during file upload.
- Fixed the problem where setting dispatch_func would cause PHP's internals to throw errors.

4.4.0 Backward incompatible changes
---

- Consistent with `PHP` official, no longer supports `PHP7.0` (@matyhtf)
- Remove the `Serialize` module, which is maintained in a separate [ext-serialize](https://github.com/swoole/ext-serialize) extension. Reason: Due to frequent changes to the `PHP` kernel, stability cannot be guaranteed
- Remove the `PostgreSQL` module and maintain it in a separate [ext-postgresql](https://github.com/swoole/ext-postgresql) extension. Reason: `PostgreSQL` uses asynchronous ways in the kernel and lacks the necessary unit tests to guarantee quality
- `Runtime::enableCoroutine` is no longer automatically compatible with the internal and external environment of the Coroutine. Once enabled, all blocking operations must be called in the Coroutine (@matyhtf)
* Due to the introduction of the new `Coroutine\MySQL` client driver, the underlying design is more standardized, but there are some small downward incompatible changes
* `Coroutine\MySQL->fetch/nextResult` is optimized for on-demand reads, which will trigger IO scheduling
* When the `defer` attribute is on, the request of `statement` needs to use `statement->recv` to receive the response
* When the `defer/fetch_mode` feature is enabled, if there is unreceived data, a new request will be banned
* Unlike asynchronous, the `connected` attribute is no longer updated based on events in real-time (It's not reliable) but is updated after the `IO` operation fails
- `Coroutine\Http\Client->set_cookie_headers` no longer have key names (#2664) (@twose)

Deprecated content
---

- The `Buffer` module will be discarded. Reason: It is highly replaceable and has low usage. It can be replaced by `PHP` string or `fopen("memory")`
- The `Lock` module will be discarded. Reason for discarding: There may be problems with locking in the Coroutine. You can use `Chan` to implement the Lock of the Coroutine version
- Since async `stream_socket_pair` is introduced, it is recommended to enable the hook by flag `SWOOLE_HOOK_STREAM_FUNCTION` instead of `SWOOLE_HOOK_STREAM_SELECT`

New features
---

+ Added [Library](https://github.com/swoole/swoole-src/tree/master/library), using pure `PHP` to write kernel functions instead of `C/C++`, providing the following features
+ Added high quality `PHP` module `Coroutine\WaitGroup` (@twose)
+ Use the `PHP` code to implement the CURL hook, one-click to make the CURL non-blocking, currently the experimental feature, you need to call `Runtime::enableCoroutine(SWOOLE_HOOK_CURL)` to open (@matyhtf) (@Yurunsoft)
+ Use `PHP` code to implement `exec`/`shell_exec` of Coroutine version (#2657) (@Yurunsof)
+ When `RuntimeHook` is turned on, the function `array_walk`, `array_walk_recursive` will be replaced by the version of Swoole, which will solve the problem that the native function cannot be reentrant, but it will not be able to traverse object (@matyhtf) (@twose)
+ Added a new Coroutine Preemptive Scheduler to prevent the Coroutine from taking too long CPU time to cause other Coroutine to starve. Open the `swoole.enable_preemptive_scheduler = On` by `php.ini`. For details, see [preemptive_scheduler](https://github.com/swoole/swoole-src/tree/master/tests/swoole_coroutine_scheduler/preemptive) (@shiguangqi)
+ Added `Timer::list()` to get `Timer\Iterator`, which can traverse all timers, `Timer\clearAll` clears all timers, `Timer\info(int $id)` gets timer information, ` Timer::stats()` gets the global timer status (#2498) (@twose)
+ Added two methods `getOption` and `setOption` for `Coroutine\Socket` (9d13c29) (@matyhtf)
+ Added `$master_pid` property and `shutdown` method to `Process\Pool` (a1d6eaa) (@matyhtf)
+ Added the 4th parameter of the constructor of `Process\Pool`, when true, the underlying layer will automatically create the Coroutine in the `onWorkerStart` callback (8ceb32cd) (@matyhtf)
+ Support non-blocking `stream_socket_pair` in Runtime hook (#2546) (@matyhtf)
+ Added `static_handler_locations` setting of `Http\Server` to set static file path (@matyhtf)
+ Added `Coroutine\Http\Client->setBasciAuth` method to automatically send `Authorization` header (#2542) (@hongbshi)
+ Added `Coroutine\Http2\Client->ping` method (40041f6) (@shiguangqi)
