Bug #46025 [Com]: zend_bailout can deadlock APC
Edit report at https://bugs.php.net/bug.php?id=46025edit=1 ID: 46025 Comment by: askalski at gmail dot com Reported by:askalski at gmail dot com Summary:zend_bailout can deadlock APC Status: No 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: I haven't tested against PHP 5.4 yet; I wonder if some of the lack of attention can be attributed to the planned bundling of Zend Optimizer+ with 5.5. The patch works (at least on the versions I've tested), but one drawback of the patch as written is that it breaks API compatibility. Modules need to be rebuilt against the updated Zend/zend.h header file to honor the new HANDLE_BLOCK_INTERRUPTIONS behavior.

[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.

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.

[2009-02-27 20:09:27] pierre at archlinux dot de This problem is still reproducable with version 5.2.9. The cgi version is affected, too (as expected). [2009-02-15 00:01:20] dan at archlinux dot org Any progress here? This is definitely reproducible and we have seen it on archlinux.org about once every 3 or 4 days- it kind of stinks. Is there any current workaround besides increasing the timeout value and hoping for the best? Running: Apache 2.2.11 PHP 5.2.8 APC 3.0.19 The remainder of the comments for this report are too long.
