Bug #46025 [Com]: zend_bailout can deadlock APC

Edit report at https://bugs.php.net/bug.php?id=46025&edit=1 ID: 46025 Comment by: pierre at archlinux dot de Reported by: askalski at gmail dot com Summary: zend_bailout can deadlock APC Status: Feedback Type: Bug Package: Reproducible crash Operating System: redhat PHP Version: 5.2.6 Assigned To: gopalv Block user comment: N Private report: N New Comment: This issue is still reproducable using php-fpm and PHP 5.3.6 with APC 3.1.9 Previous Comments: ------------------------------------------------------------------------ [2010-11-07 21:08:38] felipe@php.net Gopal, this issue has been already fixed? ------------------------------------------------------------------------ [2010-06-24 18:52:07] askalski at gmail dot com A note about the above patches: They work with the stable 3.0.19 release of APC, but not the beta 3.1.3p1. In the beta version, compilation was moved inside a HANDLE_BLOCK_INTERRUPTIONS/HANDLE_UNBLOCK_INTERRUPTIONS block, so the zend_bailout deferral is no longer safe. For example, a syntax error in the script will result in a partially compiled opcode array to be cached in APC. I don't yet have an alternate solution. ------------------------------------------------------------------------ [2010-05-31 06:54:14] askalski at gmail dot com I uploaded patches against the latest 5.1, 5.2, and 5.3 versions of PHP, for sites with production issues that can't afford to wait years for an upstream fix. ------------------------------------------------------------------------ [2009-10-21 18:42:04] askalski at gmail dot com We are using a modified 5.2 in production, so a patch against 5.2.11 (the latest release in that series) would be good. Thanks, Andy ------------------------------------------------------------------------ [2009-10-21 18:01:00] shire@php.net Lucas Nealan and I are working on fixing some items in the signals patch, and would like to push forward on this getting integrated in core. Would you be willing to try the patch for PHP to see if it corrects your problem? It would be of great use to know that it fixes your specific issue. If so let me know which specific version of PHP you want a patch against and I'll make sure we get you the latest one that cleanly patches against it. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
