2013-07-12Events: support for EPOLLRDHUP (ticket #320).Valentin Bartenev1-5/+13
Since Linux 2.6.17, epoll is able to report about peer half-closed connection using special EPOLLRDHUP flag on a read event.
2013-09-04Win32: MinGW GCC compatibility.Maxim Dounin2-3/+3
Several warnings silenced, notably (ngx_socket_t) -1 is now checked on socket operations instead of -1, as ngx_socket_t is unsigned on win32 and gcc complains on comparison. With this patch, it's now possible to compile nginx using mingw gcc, with options we normally compile on win32.

2013-04-16Events: backout eventport changes (r5172) for now.Maxim Dounin1-8/+0
Evenport method needs more work. Changes in r5172, while being correct, introduce various new regressions with current code.
2013-04-12Events: fixed typos in two previous commits.Valentin Bartenev2-2/+2
2013-04-12Events: handle only active events in eventport.Valentin Bartenev1-0/+8
We generate both read and write events if an error event was returned by port_getn() without POLLIN/POLLOUT, but we should not try to handle inactive events, they may even have no handler.
2013-04-12Events: protection from stale events in eventport and devpoll.Valentin Bartenev2-2/+8
Stale write event may happen if read and write events was reported both, and processing of the read event closed descriptor. In practice this might result in "sendfilev() failed (134: ..." or "writev() failed (134: ..." errors when switching to next upstream server. See report here: http://mailman.nginx.org/pipermail/nginx/2013-April/038421.html
2013-01-25Events: fixed null pointer dereference with resolver and poll.Ruslan Ermilov1-2/+2
A POLLERR signalled by poll() without POLLIN/POLLOUT, as seen on Linux, would generate both read and write events, but there's no write event handler for resolver events. A fix is to only call event handler of an active event.

2011-11-29Fixed AIO on Linux, broken in r4306.Maxim Dounin1-10/+10
Events from eventfd do not have c->write set, and the stale event check added in r4306 causes null pointer dereference.
2011-11-22Protection from stale write events in epoll.Maxim Dounin1-0/+12
Stale write event may happen if epoll_wait() reported both read and write events, and processing of the read event closed descriptor. Patch by Yichun Zhang (agentzh).
2011-09-20The "worker_aio_requests" directive.Igor Sysoev1-3/+13
The default value is 32 AIO simultaneous requests per worker. Previously they were hardcoded to 1024, and it was too large, since Linux allocated them early on io_setup(), but not on request itself. So with default value of /proc/sys/fs/aio-max-nr equal to 65536 only 64 worker processes could be run simultaneously. 32 AIO requests are enough for modern disks even if server runs only 1 worker.
2011-09-16Fixing Linux AIO initiatialization: AIO operations are disabled if kernelIgor Sysoev1-47/+82
does not support them. Previously worker just exited.
2011-09-16Fixing Linux AIO syscalls return value handling:Igor Sysoev1-10/+11
syscall(2) uses usual libc convention, it returns -1 on error and sets errno. Obsolete _syscall(2) returns negative value of error. Thanks to Hagai Avrahami.
