xnor	14b6261b40	Optimize resolv timer Don't call ares_timeout since it does a search through all queries. Instead, schedule a timer that fires after 1 second. If no activity happened for over 1 second do ares timeout processing, otherwise reschedule the timer to fire after the remaining timeout. This also completely avoids the ev_timer_again calls for each single fd event.	2018-05-09 23:20:13 +00:00
xnor	a5db5ef71f	Fix DNS timeouts C-ares creates up to two sockets per nameserver. With up to three nameservers in resolv.conf this makes a max of six active sockets. Having only one ev_io watcher resulted in closing watchers that were still active, needlessly resulting in DNS timeouts.	2018-05-08 21:16:28 +00:00

Optimize resolv timer

Don't call ares_timeout since it does a search through all queries.
Instead, schedule a timer that fires after 1 second. If no activity happened
for over 1 second do ares timeout processing, otherwise reschedule the timer
to fire after the remaining timeout.
This also completely avoids the ev_timer_again calls for each single fd event.

Fix DNS timeouts

C-ares creates up to two sockets per nameserver. With up to three nameservers
in resolv.conf this makes a max of six active sockets.
Having only one ev_io watcher resulted in closing watchers that were
still active, needlessly resulting in DNS timeouts.
