Bug #16548 Updated: exec or system a daemon will catch the port for this session

ID: 16548 Updated by: stefan.marquardt@hagebau.de Reported By: stefan.marquardt@hagebau.de Status: Bogus Bug Type: Apache related Operating System: RED HAT Linux 7.2 PHP Version: 4.1.2 New Comment: Now it's 100% true: Without session.auto_start = 0 it works also with apache with php compiled. So i can't use session variables. Has anybody interest to solve the problem ? I know not much from C. On which side is the error ? PHP or _mproshut (Progress) ? Previous Comments: ------------------------------------------------------------------------ [2002-04-17 07:23:29] stefan.marquardt@hagebau.de Without session.auto_start = 0 it works without problem ! (it was 1 but i use it) [root@linux /tmp]# fuser sess* sess_e2b04b5ddbae91f2c52fd86e808565f5: 20658 20661 20664 20667 [root@linux /tmp]# ps -ef | grep 20658 root 20658 1 0 12:15 ? 00:00:00 /home/dlc83e/bin/_mprshut /home/ root 20672 12474 0 12:15 pts/1 00:00:00 grep 20658 _mprshut access the session file in /tmp ! How can this happen ? ------------------------------------------------------------------------ [2002-04-17 06:04:12] stefan.marquardt@hagebau.de New information: I use now a cgi-bin version from php (before it was compiled into apache). If i start the script frist time it runs perfect and ended. (i see no php process). After that i can open any html pages without problem. If i try to open any php page in the same session it hungs. I can see the php process ans strace shows this: flock(3, LOCK_EX Is there a possibilty for debugging php itself ? I compiled not enable-debug but what can i do with that ? ------------------------------------------------------------------------ [2002-04-15 08:48:10] stefan.marquardt@hagebau.de >system(" ( $DLC/bin/_mprshut $CADB/$DB -C watchdog >/dev/null 2>&1 </dev/null )&"); >That should run the command in a sub-shell, and might solve this strange problem. >Also, have you tried enabling the sigchild handler? ./configure --help | grep sigchild Nothing helps. The developer of _mprshut can reproduce the same effect under IS(NT). ------------------------------------------------------------------------ [2002-04-12 07:04:44] stefan.marquardt@hagebau.de >> As a workaround, don't use exec :-) system("$DLC/bin/_mprshut $CADB/$DB -C watchdog 2>&1 </dev/null"); has the same effect. :-( ------------------------------------------------------------------------ [2002-04-12 05:26:26] wez@php.net Most likely _mprshut is forking but keeping some fd's open, or doing something else strange. I can't see how this is PHP's fault (it just uses popen), so I'm marking this as bogus. As a workaround, don't use exec :-) ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
