Release notes
Version 4.3.0
(stable)
New Features
---
+ `Co::getContext` to get the coroutine context object ([RFC-1018](https://github.com/swoole/rfc-chinese/issues/45)) (@twose)
+ `Co::getPcid` to get the parent coroutine ID ([RFC-1017](https://github.com/swoole/rfc-chinese/issues/41)) (@twose)
+ `Co::exists` to know if a coroutine exists (@twose)
+ Runtime Coroutine Hook supports `stream_select` (#2358) (@matyhtf)
+ `max_wait_time` configuration support in BASE mode (#2282) (@shiguangqi)
+ Support for one-way delivery tasks in the `Master/Manager/User` process ([RFC-1015](https://github.com/swoole/rfc-chinese/issues/38)) (@matyhtf)
+ `Co\Socket` has two new APIs `recvAll` and `sendAll` to ensure complete receive/send data until completion or error (3700cbb) (@twose)
+ `Process` supports the coroutine mode, please refer to ([Use Coroutine in Process](https://wiki.swoole.com/wiki/page/p-process_coro.html))
+ `Process->exportSocket` to export `Co\Socket` object (91d3621) (@matyhtf)
+ Added `Server->getCallback` method to get the callback function of the specified name of the Server (@matyhtf)

Enhancement
---
* The default max number of connections is 100K (instead of 10K) now. If the system configuration is less than this number, use the system configuration first (3d2e387) (@twose)
* Optimize the code for the `Timer` module, which now runs faster and accepts any number of arguments (#2347) (@twose)
* `Co::stats` will show more information such as the number of events, the number of registered signals, the number of AIO tasks, etc. (@matyhtf)
* `Co::getBackTrace` with no params is equivalent to `debug_backtrace` (@twose)
* `Co::listCoroutines` is renamed to `Co::list`, but the original name is still reserved as an alias (Backward compatibility) (@twose)
* `Table::exist`, `Server::exist` are renamed to `exists`, but the original name is still reserved as aliases (Backward compatibility) (@twose)
* Redis will automatically authenticate and select the corresponding database when it is automatically reconnected. Add API: `getOptions`, `getAuth`, `getDBNum` (#2303) (fdac8a3) (@windrunner414 & @twose)
* The default Socket buffer size on FreeBSD should be 2M (750a29c) (@twose)
* `Server->stats` will show `worker_dispatch_count` which can get the number of requests submitted by the master to the current process. The number of requests in the queue can be got by `worker_dispatch_count - worker_request_count` (a353808) (@matyhtf)
* Remove `Nghttp2` dependencies, no longer need to install it, configuring compilation parameters to open
* Coroutines now have no max nesting level limitation (there are no real nesting relations between coroutines) (5458cbc) (@twose)
* When the coroutine reaches the max limitation, the HTTP server will return a 503 error indicating that the service is temporarily unavailable (ebd377f) (@twose)
* `defer` will now accept a parameter whose value is the return value at the end of the coroutine ([example](https://github.com/swoole/swoole-src/commit/ef978b3b432615b0f392958145d999f4e66584eb)) (@twose)

Fixed
---
* Fixed error when the task method passed a null argument (#2366) (@twose)
* Fixed Http client send big data incomplete (#2360) (@twose)
* Fixed the bug that unprocessed data in the buffer was lost when the TCP client used the eof protocol (a59ae39) (@twose)
* Fixed async security of Server Reload (022f859) (@matyhtf)
* Fixed the index value of the connection iterator (b066146) (@twose)
* Fixed the bug that Set-Cookie special characters are too long to be outputed (#2368) (@mabu233 & @twose)
* Fixed the bug that Http client did not decode the cookie (duplicated encode when sent) (069ca5d) (@twose)
* Fixed Http client download with timeout lead to coredump (#2377) (@matyhtf & @twose)
* Fixed `__call` and `call_user_func*` lead to coredump when calling MySQL client method (#2387) (@matyhtf)
* Fixed coredump when Http2 client header name passed in a number (#2375) (@mabu233)
* Fixed `Swoole\Event::dispatch` behavior not as expected (#2390) (@matyhtf)
* Fixed `Socks5` proxy handshake failed (94ef96c) (@twose)
* Fixed a memory read error caused by a connection failure in a low-version Linux kernel (5adf625) (@matyhtf & @twose)
* Fixed the bug that the server used the timer in the BASE single-process mode not work (82eca13) (@twose)
* Fixed compilation failure due to unstable ZendAPI in low-version (768b8a7) (@shiguangqi)
* Fixed `EINVAL` when calling `sendto` (#2395) (@junwei)

Unsupported
---
- Create server or customs process after using async file IO are not allowed
- Create server or customs process in coroutine are not allowed

Removed
---
- `Websocket\Server->exists` only shows if the connection exists. Please use the `isEstablished` method to get if it is a Websocket client.
- Remove the `swoole.fast_serialize` configuration item
- Removed the PHP Warning when the `Co\Client` method return failed
- Remove the `Server->gzip` method
- Remove `PicoHttpParser` support

Remove async modules
---
Remove all async modules, separate asynchronous extensions to [async-ext](https://github.com/swoole/async-ext):

- Async functions
- MySQL
- Redis
- Http\Client
- Memory\Pool
- MsgQueue
- RingQueue
