Subject: SIGWINCH/NOACCEPT signal is disabled now in non-daemon mode.
X-Git-Tag: release-1.1.1~1
X-Git-Url: http://www.kaiwu.me/postgresql/commit/?a=commitdiff_plain;h=566dfe0c7fc4ca8405cbed3f9cdacea29d584055;p=nginx.git

SIGWINCH/NOACCEPT signal is disabled now in non-daemon mode.
Non-daemon mode is currently used by supervisord, daemontools and so on
or during debugging. The NOACCEPT signal is only used for online upgrade
which is not supported when nginx is run under supervisord, etc.,
so this change should not break existant setups.
