Bug #80881 [Com]: open_basedir crashes Apache

Edit report at https://bugs.php.net/bug.php?id=80881&edit=1 ID: 80881 Comment by: simbiat at outlook dot com Reported by: simbiat at outlook dot com Summary: open_basedir crashes Apache Status: Feedback Type: Bug Package: Safe Mode/open_basedir Operating System: Windows 10.0.19042.868] PHP Version: 8.0.3 Assigned To: cmb Block user comment: N Private report: N New Comment: Based on that manual, should not the full dump that was generated by Windows for httpd.exe be enough? It can be taken from https://1drv.ms/u/s!AsaK_C2Xv0I4gunuXIptXRyLcx8YymA?e=NmL4AA Also I'm not sure I understand what you mean by "on-demand" and why it's normal for Apache to crash this way. From what I understand "ondemand" is relevant for PHP-FPM, but it's not available for Windows, from what I know. I was able to replciate the crash with mod_php and mod_fcgi.

Assuming you have on-demand enabled, the former is to be expected. You're generally better off to download a copy of the Website and work with this. The stack backtrace would be way more helpful, if you had debug symbols for PHP installed. You can get them from windows.php.net; they're called "debug pack". Then generate a stack backtrace[1] with the Debug Diagnostic Tool and make sure that the debug symbols are loaded. Also, it might help if you can provide the output of fsutil reparsePoint query C:\Users\simbi\OneDrive [1] <https://bugs.php.net/bugs-generating-backtrace-win32.php> ------------------------------------------------------------------------ [2021-03-18 11:16:59] simbiat at outlook dot com Description: ------------ It looks like after some update for Windows (KB5000802 and/or later one) if you set open_basedir it will slow PHP down and cause Apache to crash. More details including text of the dump can be found here https://www.apachelounge.com/viewtopic.php?p=39993 In summary: even on latest builds of Apache both PHP 7.4.16 and 8.0.3 crash if open_basedir is set. This is true both for mod_php and mod_fcgi (errors do differ a bit, of course). Once open_basedir is commented out the crashes stop and PHP seems to start working much faster, too. Considering that !analyze -v command indicates "virtual_realpath" component on the 2nd line of the stack and open_basedir is supposed to disable realpath cache, I presume, that there is an issue in how it is being disabled. Test script: --------------- Not applicable. Any script does this Expected result: ---------------- Apache does not crash Actual result: -------------- Apache restarts child process ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=80881&edit=1
