#43491 [Opn->Asn]: Under certain conditions, file_exists() never returns

ID: 43491 Updated by: tony2001@php.net Reported By: amccardie at cox dot net -Status: Open +Status: Assigned Bug Type: Filesystem function related Operating System: Windows 2003 SP2 PHP Version: 5.2-CVS-2007-12-05 -Assigned To: +Assigned To: dmitry Previous Comments: ------------------------------------------------------------------------ [2007-12-05 15:25:13] amccardie at cox dot net Exactly. The script hangs at the call to file_exists(). Also, using the CLI, the php.exe process goes to 99% CPU time. When it happens with mod_php, the httpd.exe process hogs the CPU. ------------------------------------------------------------------------ [2007-12-05 11:03:43] jani@php.net So it just hangs there or what? (script never ends) ------------------------------------------------------------------------ [2007-12-04 16:00:55] amccardie at cox dot net As suggested, I tried the latest snapshot. I see the same results as described above. BTW, this happens with the CLI as well as mod_php. ------------------------------------------------------------------------ [2007-12-04 00:19:33] amccardie at cox dot net Description: ------------ When open_basedir is set in php.ini, file_exists() will never return if called with an argument containing a ":/" or ":\\" without a corresponding drive letter. Example: file_exists("C:/foo.txt") => works file_exists("C:\\foo.txt") => works file_exists(":/foo.txt") never returns. file_exists(":\\foo.txt") never returns. Tested under Windows 2003 Server with SP2 and Windows XP Pro, both using Apache 2.2.6/mod_php. Reproduce code: --------------- copy php.ini-dist to php.ini set open_basedir = C:/ <?php //Should print "no" print file_exists("C:/foo.txt")?"yes\n":"no\n"; //Should also print "no" but never returns, //causing high CPU, if open_basedir is set print file_exists(":/foo.txt")?"yes\n":"no\n"; exit; ?> Expected result: ---------------- no no Actual result: -------------- no file_exists() call never returns ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=43491&edit=1
