2015-03-27Events: fixed possible crash on start or reload.Valentin Bartenev1-2/+2
The main thread could wake up and start processing the notify event before the handler was set.
2015-03-20Removed unix ngx_threaded and related ngx_process_changes.Ruslan Ermilov1-1/+0
2015-03-14Events: implemented epoll notification mechanism.Valentin Bartenev1-2/+139
2015-03-14Thread pools implementation.Valentin Bartenev1-0/+1
2014-09-01Events: processing of posted events changed from LIFO to FIFO.Valentin Bartenev1-1/+2
In theory, this can provide a bit better distribution of latencies. Also it simplifies the code, since ngx_queue_t is now used instead of custom implementation.
2014-09-01Events: removed broken thread support from posted events.Valentin Bartenev1-20/+6
It's mostly dead code. And the idea of thread support for this task has been deprecated.
2014-05-23Events: use eventfd() instead of syscall(SYS_eventfd) if possible.Ruslan Ermilov1-4/+4
This fixes --with-file-aio support on systems that lack eventfd() syscall, notably aarch64 Linux. The syscall(SYS_eventfd) may still be necessary on systems that have eventfd() syscall in the kernel but lack it in glibc, e.g. as seen in the current CentOS 5 release.
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.
2012-07-24Fixed compilation with -Wmissing-prototypes.Ruslan Ermilov1-5/+9
2012-04-03Fixed spelling in multiline C comments.Ruslan Ermilov1-2/+2
2012-01-18Copyright updated.Maxim Konovalov1-0/+1
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.
