Bug #68587 [Opn]: auto_prepend_file breaks Apache2 virtual hosts if same contents

Edit report at https://bugs.php.net/bug.php?id=68587&edit=1 ID: 68587 User updated by: dante at lorenso dot com Reported by: dante at lorenso dot com Summary: auto_prepend_file breaks Apache2 virtual hosts if same contents Status: Open Type: Bug Package: Apache2 related Operating System: Ubuntu 14.04 LTS PHP Version: 5.5.19 Block user comment: N Private report: N New Comment: No success :\ These setting also DID NOT work... php_admin_value xcache.readonly_protection On php_admin_value xcache.mmap_path /tmp/xcache1 php_value auto_prepend_file /www/prod/keydb/public/bootstrap.php I'm wondering if those tickets: http://xcache.lighttpd.net/ticket/291 http://xcache.lighttpd.net/ticket/296 Might have been referencing other bugs and maybe the auto_prepend_file is a special case of cache loading that wasn't addressed? Unless I can turn XCache ON and not have this problem, it is still a BUG. I can work around the bug by turning XCache OFF, but that shouldn't be the right answer. -- Dante Previous Comments: ------------------------------------------------------------------------ [2014-12-11 05:55:24] dante at lorenso dot com Default Ubuntu 14.04 xcache settings are in use ... here is the default configuration: > php -i | grep -i xcache /etc/php5/cli/conf.d/20-xcache.ini, with XCache v3.1.0, Copyright (c) 2005-2013, by mOo with XCache Optimizer v3.1.0, Copyright (c) 2005-2013, by mOo with XCache Cacher v3.1.0, Copyright (c) 2005-2013, by mOo with XCache Coverager v3.1.0, Copyright (c) 2005-2013, by mOo XCache XCache Version => 3.1.0 xcache.coredump_directory => no value => no value xcache.disable_on_crash => Off => Off xcache.experimental => Off => Off xcache.test => Off => Off XCache Cacher XCache Cacher Module => enabled xcache.admin.enable_auth => On => On xcache.allocator => bestfit => bestfit xcache.cacher => On => On xcache.count => 1 => 1 xcache.gc_interval => 0 => 0 xcache.mmap_path => /dev/zero => /dev/zero xcache.readonly_protection => Off => Off xcache.shm_scheme => mmap => mmap xcache.size => 60M => 60M xcache.slots => 8K => 8K xcache.stat => On => On xcache.ttl => 0 => 0 xcache.var_allocator => bestfit => bestfit xcache.var_count => 1 => 1 xcache.var_gc_interval => 300 => 300 xcache.var_maxttl => 0 => 0 xcache.var_namespace => cheese => cheese xcache.var_namespace_mode => 1 => 1 xcache.var_size => 4M => 4M xcache.var_slots => 8K => 8K xcache.var_ttl => 0 => 0 XCache Coverager XCache Coverager Module => enabled xcache.coveragedump_directory => no value => no value xcache.coverager => Off => Off xcache.coverager_autostart => On => On XCache Optimizer XCache Optimizer Module => enabled xcache.optimizer => Off => Off I will play more with some of these settings to see if I can re-enable XCache to work around the problem. ------------------------------------------------------------------------ [2014-12-11 05:39:36] dante at lorenso dot com The OPcache is turned on ... but I don't think this is the problem. opcache.use_cwd On On This problem is fixed by turning OFF XCache but leaving OPcache unchanged. I tried some attempts to modify the XCache namespace, but this DID NOT WORK: <VirtualHost...> php_admin_value xcache.var_namespace acd php_value auto_prepend_file /www/dev/acd/public/bootstrap.php </VirtualHost> <VirtualHost...> php_admin_value xcache.var_namespace keydb php_value auto_prepend_file /www/prod/keydb/public/bootstrap.php </VirtualHost> I don't think the var_namespace affected XCache's knowledge of the original file path. And like I said, changing the contents of the bootstrap.php so that each virtual host had DIFFERENT data did work. Unfortunately, in these two projects, I'm using the same bootstrap.php from source control and do not want to force them to be different just to work around the XCache bug. -- Dante ------------------------------------------------------------------------ [2014-12-11 05:35:59] requinix@php.net According to http://xcache.lighttpd.net/ticket/291 http://xcache.lighttpd.net/ticket/296 this problem shouldn't exist in 3.1, which Ubuntu 14.04 and the ondrej PPA have. As per comment 18 on ticket 296, ReadonlyProtection http://xcache.lighttpd.net/wiki/ReadonlyProtection may help, and/or setting xcache.mmap_path to two different locations. http://xcache.lighttpd.net/wiki/XcacheIni#XCacheCacher Unfortunately I don't know enough about XCache to offer more than that. ------------------------------------------------------------------------ [2014-12-11 04:57:10] dante at lorenso dot com Problem resolved by disabling XCache. On Ubuntu 14.04 LTS, the following command was run: > php5dismod xcache Then apache2 was restarted, and the problem has gone away. The proper auto_prepend_file is being loaded from the virtual host now. To confirm, I run the following command: > php5enmod xcache and restart apache. The problem returns. So, for now, I will leave XCache disabled. -- Dante ------------------------------------------------------------------------ [2014-12-11 04:47:09] requinix@php.net Using OPcache? What's the value of opcache.use_cwd? If off, does turning it on fix the problem? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
