workman websocket问题

iqige 更新于2019-09-16

经常出现一下这样的错误信息，然后进程正常退出

process_timeout:

#20 {main}

还有，status中的进程没有busy，但是想要连上websocket需要随缘

这是业务处理超时导致的，当没有设置超时处理函数时或者超时处理函数返回为空时，businessworker进程就会因此退出，从而导致businessworker与gateway的连接中断，所以从两方面着手：
1、排查业务阻塞的原因；
2、设置处理超时回调以捕捉业务异常，避免进程退出； $businessworker->processTimeoutHandler(String $trace, Exception $exception)

根据错误栈的提示，不是应该阻塞在检查客户端是否在线这一步吗，我看了下sendAndRecv这个方法，已经设置了超时。另外，有个问题，如果出现了busy进程，strace -ttp pid 配合php start.php status -d ,追踪是这样子的：
11:17:54.169967 rt_sigreturn({mask=[]}) = 45
11:17:54.170040 recvfrom(6, 0x7f8dbea58018, 655350, 0, NULL, NULL) = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
11:17:55.167907 --- SIGUSR2 {si_signo=SIGUSR2, si_code=SI_USER, si_pid=18243, si_uid=0} ---
11:17:55.168112 rt_sigreturn({mask=[]}) = 45
11:17:55.168265 recvfrom(6, 0x7f8dbea58018, 655350, 0, NULL, NULL) = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
11:17:56.170834 --- SIGUSR2 {si_signo=SIGUSR2, si_code=SI_USER, si_pid=18243, si_uid=0} ---
11:17:56.170961 rt_sigreturn({mask=[]}) = 45
11:17:56.171059 recvfrom(6, 0x7f8dbea58018, 655350, 0, NULL, NULL) = ? ERESTARTSYS (To be restarted if SA_RESTART is set)
11:17:57.171275 --- SIGUSR2 {si_signo=SIGUSR2, si_code=SI_USER, si_pid=18243, si_uid=0} ---
11:17:57.171352 rt_sigreturn({mask=[]}) = 45
猜测，是不是就是卡在检查是否在线这一步？

这里的业务处理超时是针对 Events 的四个 onXXXX回调里的整体业务存在阻塞时而言的，这和sendAndRecv() 这个tcp连接的超时完全不是一回事，反过来，根据题示栈信息也可以看出这个方法也是在onClose 回调触发的，不管怎样，这也只是相当于整体业务里的一个局部子单元业务。

原来如此
