Hi,all
I find it hard to understand in function ngx_epoll_process_events as following.
if ((revents & (EPOLLERR|EPOLLHUP))
&& (revents & (EPOLLIN|EPOLLOUT)) == 0)
{
/*
* if the error events were returned without EPOLLIN or EPOLLOUT,
* then add these flags to handle the events at least in one
* active handler
*/

revents |= EPOLLIN|EPOLLOUT;
}
As the comment said we should check if ((revents & (EPOLLERR|EPOLLHUP))==0) that we can end the connection when EPOLLERR and EPOLLHUP is returned.
,but why not this? Help...
