v4.4.0

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 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  • Unlike asynchronous, the connected attribute is no longer updated based on events in real-time (It's not reliable) but is updated after the IO operation fails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, 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) (@Yurunsoft)
  • 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 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 (8ceb32c) (@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)
• Added task_use_object (#2659) (aa01317) (@twose)

Enhancement

• New Coroutine\MySQL\Client driver (#2538) (@twose)
  • The underlying programming mode using C++ and Coroutine (sync writing, async performance)
  • Support SSL connection (configure ['ssl' => true] when connect)
  • Support request with large data (unlimited)
  • Support response with large data (unlimited)
  • Support fetch to read by line (now fetch is read on demand, data without fetch does not consume user memory) (#2106)
  • Support nextResult read on demand (ibid)
  • Optimized protocol parser
  • date related type decimal precision support
  • Error code and information are consistent with PDO/mysqli
• Coroutine\Redis compatibility mode, enabled by $redis->set(['compatibility_mode' => true]), which can make the result of hmGet/hGetAll/zRange/zRevRange/zRangeByScore/zRevRangeByScore consistent with phpredis (#2529) (@caohao-php)
• Now 100K Coroutine are allowed to exist at the same time by default (c69d320) (@twose)
• Support bailout (can exit the process correctly when a fatal error occurs in the Coroutine) (#2579) (@twose)
• Server can display a friendly 400/404/503 when error occurred (@matyhtf) (f3f2be9)

• Floating point calculation optimization (#2572) (@tangl163)
• All built-in classes prohibit cloning/serializing/unseting-declared-properties (f9c974b) (@twose)

• go() + Swoole\Event::wait() may be deprecated
