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?

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.
