Fix EVDNS_BASE_DISABLE_WHEN_INACTIVE (#1493) I faced with strange problem: event loop doesn't exit after dns resolving with `EVDNS_BASE_DISABLE_WHEN_INACTIVE`. Stand: - Ubuntu 22; - libevent release-2.1.12-stable - `resolve.conf` contains 2 nameservers; - I use `evdns_base_new` with `EVDNS_BASE_DISABLE_WHEN_INACTIVE | EVDNS_BASE_INITIALIZE_NAMESERVERS` to avoid OS specific code. After small investigation, look like events related with dns sockets added to event_base before `evdns->disable_when_inactive` was initialized. `libevent` did epoll_ctl(DEL) after resolving completed on the first socket, but the second socket remained in the `epoll` interest list.
