annotate src/event/ngx_event_accept.c @ 605:5dac8c7fb71b release-0.3.24
nginx-0.3.24-RELEASE import
*) Workaround: for bug in FreeBSD kqueue.
*) Bugfix: now a response generated by the "post_action" directive is
not transferred to a client.
*) Bugfix: the memory leaks were occurring if many log files were used.
*) Bugfix: the first "proxy_redirect" directive was working inside one
location.
*) Bugfix: on 64-bit platforms segmentation fault may occurred on start
if the many names were used in the "server_name" directives; the bug
had appeared in 0.3.18.
