Previous Comments: ------------------------------------------------------------------------ [2011-04-08 15:48:09] dmitry@php.net the listening socket is already set into SO_REUSEADDR mode, so it's not a problem to start new PHP FastCGI process(es) while another is not finished yet. ------------------------------------------------------------------------ [2008-11-16 16:09:20] glen at delfi dot ee ping? for now the patch only makes php-fcgi to close listening socket on SIGTERM, so if it continues to run, new processes are able to spawn to the same tcp port. http://cvs.pld-linux.org/cgi-bin/cvsweb.cgi/SOURCES/php-fcgi-graceful.patch?rev=1.8 ------------------------------------------------------------------------ [2008-07-29 09:22:33] glen at delfi dot ee Didn't know about SIGQUIT, but ok, you can keep the signal handlers, but closing listening sockets on SIGTERM does not break process managers, it will do only good. as for original behaviour, if you have some long running request running and you terminate fcgi processes with SIGTERM you can not start new fcgi processes on same tcp port (as the socket is still in use) so to summarize signal handlers would be: SIGTERM, SIGUSR1 - graceful shutdown -- listening sockets are closed, processing continues until scripts finish SIGINT, SIGQUIT (, SIGKILL) - immediate shutdown -- listening sockets are closed, processes are terminated unconditionally whether they are idle or not. ------------------------------------------------------------------------ [2008-07-29 09:00:33] dmitry@php.net FastCGI PHP SAPI supports only gracefull restart initiated by SIGTERM and SIGUSR1, however you still able to terminate worker processes with sending SIGINT/SIGQUIT to process group. I'm not going to change it as it may break behavior with some FastCGI managers. ------------------------------------------------------------------------ [2008-06-11 11:18:40] glen at delfi dot ee hi any progress with the patch? i can confirm that it works without problems since i initially created the patch. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
