This article mainly shows you the "Swoole 1.10.0 new version of what are the new features", the content is easy to understand, clear, hope to help you solve your doubts, the following let the editor lead you to study and learn "what are the new features of the new version of Swoole 1.10.0" this article.

Automatic DNS parsing

The new version of asynchronous client no longer needs to use swoole_async_dns_lookup to resolve domain names, and the underlying layer implements automatic domain name resolution. Client can pass in the domain name directly when executing the connect method.

$client = new swoole_client (SWOOLE_SOCK_TCP, SWOOLE_SOCK_ASYNC); $client- > on ("connect", function (swoole_client $cli) {$cli- > send ("GET / HTTP/1.1\ r\ n\ r\ n\ n");}); $client- > on ("receive", function (swoole_client $cli, $data) {echo "Receive: $data"; $cli- > send (str_repeat ('Aids, 100). "\ n"); sleep (1);}) $client- > on ("error", function (swoole_client $cli) {echo "error\ n";}); $client- > on ("close", function (swoole_client $cli) {echo "Connection close\ n";}); / / Asynchronous domain name resolution $client- > connect ('www.baidu.com', 9501)

Slow request log

The new version adds the ability to track slow requests and record the PHP function call stack for slow requests.

Function test () {test_sleep ();} function test_sleep () {echo "sleep 5\ n"; sleep (5);} $server = new swoole_server ('127.0.0.1, 9501); $server- > set ([' worker_num' = > 1, 'task_worker_num' = > 1,' trace_event_worker' = > true, 'request_slowlog_timeout' = > 1,' request_slowlog_file' = >'/ tmp/trace.log',]) $server- > on ('Receive', function ($serv, $fd, $reactor_id, $data) {test (); $serv- > send ($fd, "Swoole: $data");}); $server- > start ()

After the slow request is processed, a line of error message is printed in the / tmp/trace.log log:

[08-Jan-2018 15:21:57] [worker#0] pid 26905 [0x00007f60cda22340] sleep () / home/htf/workspace/swoole/examples/server/trace.php:10 [0x00007f60cda222e0] test_sleep () / home/htf/workspace/swoole/examples/server/trace.php:4 [0x00007f60cda22280] test () / home/htf/workspace/swoole/examples/server/trace.php:28 [0x00007f60cda22190] {closure} () / home/htf/workspace/swoole/examples/server/ Trace.php:42 [0x00007f60cda22140] start () / home/htf/workspace/swoole/examples/server/trace.php:42

New STREAM module

The new stream module makes the communication between Reactor, Worker and Task processes more flexible and decoupled to the maximum extent. Complex online projects use stream mode, which makes request allocation and scheduling more efficient.

Serv = new swoole_server ("127.0.0.1", 9501); $serv- > set ('dispatch_mode' = > 7,' worker_num' = > 2,)); $serv- > on ('receive', function (swoole_server $serv, $fd, $threadId, $data) {var_dump ($data); echo "# {$serv- > worker_id} > received length=". Strlen ($data). "\ n";}); $serv- > start ()

The communication between Reactor and Worker is enabled with dispatch_mode = 7.

The communication between Worker and Task is enabled with task_ipc_mode = 4.

Add Event::cycle function

User code can customize a hook function for EventLoop, which is called at the end of each round of event loops. It is convenient to use Generator + Yield or Promise-like Swoole framework to implement your own scheduler.

Swoole\ Timer::tick (2000, function ($id) {var_dump ($id);}); Swoole\ Event::cycle (function () {echo "hello [1]\ n"; Swoole\ Event::cycle (function () {echo "hello [2]\ n"; Swoole\ Event::cycle (null);});})
