Latest PECL Releases:

• rdkafka 3.1.2
  * Fix build

• ahocorasick 0.0.7
  Issue #21 fixed. Problem with buffering all previous searches in the trie.
• swoole 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 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 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 CoroutineMySQL client driver, the underlying design is more standardized, but there are some small downward incompatible changes
    • CoroutineMySQL->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    • Unlike asynchronous, the connected attribute is no longer updated based on events in real-time (It's not reliable) but is updated after the IO operation fails
  • CoroutineHttpClient->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, using pure PHP to write kernel functions instead of C/C++, providing the following features
    • Added high quality PHP module CoroutineWaitGroup (@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 (@shiguangqi)
  • Added Timer::list() to get TimerIterator, which can traverse all timers, TimerclearAll clears all timers, Timerinfo(int $id) gets timer information, Timer::stats() gets the global timer status (#2498) (@twose)
  • Added two methods getOption and setOption for CoroutineSocket (9d13c29) (@matyhtf)
  • Added $master_pid property and shutdown method to ProcessPool (a1d6eaa) (@matyhtf)
  • Added the 4th parameter of the constructor of ProcessPool, 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 HttpServer to set static file path (@matyhtf)
  • Added CoroutineHttpClient->setBasciAuth method to automatically send Authorization header (#2542) (@hongbshi)
  • Added CoroutineHttp2Client->ping method (40041f6) (@shiguangqi)
  • Added task_use_object (#2659) (aa01317) (@twose)

  Enhancement

  • New CoroutineMySQLClient driver (#2538) (@twose)

    • Optimized protocol parser
    • date related type decimal precision support
    • Error code and information are consistent with PDO/mysqli

  • Now 100K Coroutine are allowed to exist at the same time by default (c69d320b) (@twose)
  • Support bailout (can exit the process correctly when a fatal error occurs in the Coroutine) (#2579) (@twose)
