Previous Comments: ------------------------------------------------------------------------ [2015-07-05 02:34:11] ben at dougherty dot net dot au The sample script chx gave wasn't always broken/working for me but here is a minimalist version around the Drupal core patch he mentioned that never works: http://privatepaste.com/8904019d51 It's broken on: PHP 5.6.10-1+deb.sury.org~trusty+1 (cli) Copyright (c) 1997-2015 The PHP Group Zend Engine v2.6.0, Copyright (c) 1998-2015 Zend Technologies with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2015, by Zend Technologies Here's a full strace: http://privatepaste.com/c28af303c2 and the php.ini settings: http://privatepaste.com/ce0c4bed5d Works fine on: PHP 5.5.9-1ubuntu4.9 (cli) (built: Apr 17 2015 11:44:57) Copyright (c) 1997-2014 The PHP Group Zend Engine v2.5.0, Copyright (c) 1998-2014 Zend Technologies with Zend OPcache v7.0.3, Copyright (c) 1999-2014, by Zend Technologies ------------------------------------------------------------------------ [2015-07-05 00:31:50] chx@php.net Sorry, I forgot to add Expected bool(true) bool(true) Instead we got bool(true) bool(false) as and it's not in the opcache_get_status dump either. Also, as I mentioned, https://www.drupal.org/files/issues/2513326_34.patch longer hits. ------------------------------------------------------------------------ [2015-07-05 00:29:56] chx@php.net Description: ------------ opcache seems broken, plain and simple. The INI settings are the same to PHP 5.5 where the test script worked. PHP 5.6.10-1+deb.sury.org~trusty+1 (cli) Copyright (c) 1997-2015 The PHP Group Zend Engine v2.6.0, Copyright (c) 1998-2015 Zend Technologies with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2015, by Zend Technologies When strace'ing we have found that after the stat to test.php working versions issued fcntl(3, F_SETLKW, {type=F_WRLCK, whence=SEEK_SET, start=0, len=1}) = 0 fcntl(3, F_SETLK, {type=F_UNLCK, whence=SEEK_SET, start=0, len=1}) = 0 where open("/tmp/.ZendSem.amvda2", O_RDWR|O_CREAT|O_EXCL, 0600) = 3 but this more seems a corollary than a cause, still I thought I'll mention it. Test script: --------------- <?php var_dump(opcache_compile_file('test.php')); var_dump(opcache_is_script_cached("test.php")); $scripts = opcache_get_status(TRUE); var_dump($scripts); ?> test.php can be either empty or just <?php . It also broke https://www.drupal.org/files/issues/2513326_34.patch (but that's a hack) I got a report it working with 5.6.4; I haven't run the reproduction scripts with 5.6.4. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69995&edit=1
