ID: 47675 Comment by: bryan at stansell dot org Reported By: cs at ecn dot purdue dot edu Status: No Feedback Bug Type: Apache2 related Operating System: Solaris 10 PHP Version: 5.2.9 New Comment:
I've encountered this problem using OpenSolaris (snv_115), apache 1.3.41 and php-5.2.12 (via mod_php5). It was also a problem with php 5.2.9. My apache processes continue to accumulate open files pointing to the directory which contains the php script. I am using gcc 4.3.3, gnu as, and solaris ld. It makes me wonder if it's a compiler-related thing. I was also talking to a friend and we checked his httpd processes and saw the same file descriptor leak. His setup is Solaris 9 (sparc), apache 1.3.41, php 4.4.8, and gcc 4.0.2. I worked around my problem by unsetting HAVE_BROKEN_GETCWD. I have a couple other ideas on possibly narrowing down the problem, but I haven't had a chance to try them.

Thank you for your interest in PHP. I run OpenSolaris 2009.06 with Apache 2.2.11 and cannot reproduce this behavior. The old_cwd_fd is closed. ZEND_EXIT calls zend_bailout which jumps back to the end of the try/catch block in php_execute_script where the descriptor is closed. Can you be more specific about the behavior you encountered? ------------------------------------------------------------------------ [2009-03-16 16:25:21] cs at ecn dot purdue dot edu I am using apache 2.2.11. ------------------------------------------------------------------------ [2009-03-16 16:21:51] j...@php.net Apache1 or Apache2 ? ------------------------------------------------------------------------ [2009-03-16 14:07:47] cs at ecn dot purdue dot edu Description: ------------ mod_php contains a potential file descriptor leak on Solaris 10 when script executes "exit()". Reproduce code: --------------- <?php exit(0); ?> The change in behavior is due to the addition of HAVE_BROKEN_GETCWD for Solaris 10. In php_execute_script, a file descriptor is opened to hold the current working directory, but is not closed in the case where php code may not return to this function after executing a script. mod_php isn't aware of the resource that was allocated and not freed. Expected result: ---------------- Normally web server runs for days without resource trouble. In the case where a PHP script does an "exit(0)", the web server will run out of file descriptors and will need restarting. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=47675&edit=1
