nginx.git/src/event/modules, branch release-1.1.8

The "worker_aio_requests" directive.

2011-09-20T07:30:09+00:00

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.

Fixing Linux AIO initiatialization: AIO operations are disabled if kernel

does not support them.  Previously worker just exited.

Fixing Linux AIO syscalls return value handling:

2011-09-16T12:43:16+00:00

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.

fix building by gcc 4.6 without --with-debug

2011-04-23T17:25:06+00:00

*) introduce ngx_time_sigsafe_update() to update the error log time only

2010-03-25T09:10:10+00:00

*) change ngx_time_update() interface

*) use previously cached GMT offset value to update time from a signal handler

2010-03-13T18:08:07+00:00

*) change ngx_time_update() interface since there are no notification methods
   those return time

do not update time in the timer signal handler,

2010-03-12T14:31:47+00:00

since localtime_r() is not Async-Signal-Safe function

add NGX_PROCESS_HELPER process status

2009-11-23T15:46:21+00:00

FreeBSD and Linux AIO support

2009-08-28T08:12:35+00:00

*) move small declarations in appropriate places and delete the surplus

2009-08-25T09:09:13+00:00

   header files
*) delete insignificant comments
