nginx: src/event/ngx_event_accept.c annotate

annotate src/event/ngx_event_accept.c @ 487:31ff3e943e16 release-0.1.18

nginx-0.1.18-RELEASE import *) Workaround: the default values of the devpoll_events and the devpoll_changes directives changed from 512 to 32 to be compatible with Solaris 10. *) Bugfix: the proxy_set_x_var and fastcgi_set_var directives were not inherited. *) Bugfix: in the redirect rewrite directive the arguments were concatenated with URI by the "&" rather than the "?". *) Bugfix: the lines without trailing ";" in the file being included by the ngx_http_geo_module were silently ignored. *) Feature: the ngx_http_stub_status_module. *) Bugfix: the unknown log format in the access_log directive caused the segmentation fault. *) Feature: the new "document_root" parameter of the fastcgi_params directive. *) Feature: the fastcgi_redirect_errors directive. *) Feature: the new "break" modifier of the "rewrite" directive allows to stop the rewrite/location cycle and sets the current configuration to the request.
