#26771 [Sus]: register_tick_funtions crash under threaded webservers

ID: 26771 Updated by: betz@php.net Reported By: info at tphnet dot com Status: Suspended Bug Type: *General Issues Operating System: * (ZTS only!) PHP Version: 5CVS, 4CVS (2005-06-17) New Comment: I added a warning to the docs Friedhelm Previous Comments: ------------------------------------------------------------------------ [2005-08-10 20:02:22] rasmus@php.net You are probably right that the tick stuff is broken in ZTS mode. But I doubt anybody is all that interested in fixing it as it is a very fringe feature in a very fringe environment. You can always hope, but chances are you will need to dig into the code yourself and send us a patch to get any movement on this. ------------------------------------------------------------------------ [2004-01-02 19:23:33] info at tphnet dot com Description: ------------ While searching the bug database I found some similar problems, but all were suspended. I wasn't sure if it was useful to reply to one of those (Most recent one: http://bugs.php.net/bug.php?id=26286). Well anyways, here goes: The problem is very simple. I just copy and paste the 'tick' example from the php manual into a new php file an try to execute it on my apache2 server. The apache child process crashes, restarts, crashes, restarts and eventually just stops restarting. When I comment out the line 'register_tick_function', everyting works just fine. Also, when I start the file from the CLI version of PHP it is executed without any problems. I'm using PHP 4.3.4 and Apache 2.0.48 (in conjunction with php4apache2.dll). Reproduce code: --------------- http://nl.php.net/manual/en/control-structures.declare.php See Example 11-1 Actual result: -------------- [Sat Jan 03 01:11:04 2004] [notice] Parent: child process exited with status 3221225477 -- Restarting.

It's filled with the above lines, the status code is the same for every restart. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=26771&edit=1
