I could disable APC but APC improves the performance great! Is there a known bug or could I do something else to prevent these errors? I'm using Ubuntu 8.04 LTS with PHP 5.2.4. Edit/Update (from comments): I use the Zend Framework Autoloader and these error never occurred before I enabled APC. A few moments ago I get for example that error: Fatal error: require(): Cannot redeclare class zend_db_adapter_abstract

Do not include the said file twice. Use include_once. Or failing that, wrap all definitions in if (!class_defined("xxx")) { –mario Jan 1 '11 at 19:51 In addition to only using include_once, try and re-architect the application to make use of class autoloading, so that PHP will only include files when needed. Also stick to common-sense things, like one class per file, etc. –Rob Jan 1 '11 at 20:10 1 what do you mean by xxx? is xxx actually the class you want to load? –The Surrican Jan 1 '11 at 20:10 I use the Zend Framework Autoloader and these error never occurred before I enabled APC.

Anyways this was driving me crazy today and http://stackoverflow.com/questions/4575341/php-with-apc-fatal-errors-cannot-redeclare-class I got all kinds of strange errors (Cannot redeclare class, class not found,...) Maybe it would be nice to check the apc ini settings while bootstrapping n98-magerun and printing a warning is problems have been detected similar to the checks done in the composer installer: http://getcomposer.org/installer This works for me as a workaround to make sure apc is disabled on a server where I'm not allowed to https://github.com/netz98/n98-magerun/issues/153 touch php.ini: php -d apc.enable_cli=0 n98-magerun.phar netz98 member cmuench commented Jun 12, 2013 @fbrnc Thanks. I currently had no problems with APC cache. But good to know. I checked composer install.php script. And it seems that we could use it and replace all the composer.phar calls with n98-magerun.phar. What do you think about providing this installation script? fbrnc commented Jun 12, 2013 Hi Christian, this is not so much about having an installer (although this won't hurt and is a nice addition, but installing magerun isn't a big deal anyways). In our case n98-magerun will be deployed to a server as part of a project, so we will run into issue while running n98-magerun and not while installing it initially (because this is not happening). Having a runtime check might be a better solution. On the other hand this could be annoying if it always shows up even if the settings don't match, even if there is no real problem (or is it always a problem with apc? with all versions of PHP and APC?)

Categories: Developing Tags: Code APC stands for the Alternative PHP Cache. PHP is a dynamic language that is compiled on-demand into bytecode at execution time. To improve performance, APC stores this bytecode https://pantheon.io/docs/alternative-php-cache/ so that it can be reused instead of having to be recompiled each time. Pantheon provides APC by default across all plans, but the size of the APC memory cache (apc.shm_size) varies depending https://phabricator.wikimedia.org/T45563 on the service level. Frequently Asked Questions Can APC be used as a cache backend on Pantheon? Yes, APC can be used as a cache backend or a "key-value store"; however, this is not cannot redeclare recommended. APC lacks the ability to span multiple server environments. Instead, Pantheon provides Redis as a caching backend, which has better performance. What happens if the APC memory cache is too small? If the size of the scripts loaded exceed the size of the APC cache, the cache will be flushed and rebuilt, resulting in slow execution time. Symptoms of this will include the following message in dev cannot redeclare class environments and in watchdog logs: Warning: require_once(): Unable to allocate memory for pool. In these circumstances, either increasing the SHM size by upgrading your account, or reducing the amount of scripts read by PHP by disabling unneeded modules typically resolves the issue. To learn more about how much memory your site is using, visit the site's New Relic dashboard. How can I determine what my current APC settings are? Search for shm_size in phpinfo. See Securely Working with phpinfo. Can the shm_size be configured manually? No, as this is not a runtime configuration, the shm_size cannot be changed. If a greater shm_size is needed, then the two options available are to optimize the codebase to operate within the service level, or to upgrade the site account for a larger shm_size allocation. Troubleshooting I got a fatal error about redeclaring a class in Drupal core; what should I do? In some rare cases, there is a known issue with APC where it attempts to load a file that has already been cached. For example: Fatal error: Cannot redeclare class InsertQuery_mysql in ... on line 87 If this happens often, a workaround would be to place the following at the top of th

You note your cache configuration in the bug report, is that means if you comment the following line, the error disappears? $wgMainCacheType = CACHE_ACCEL; $wgCacheDirectory = "$IP/cache"; Could you also do a search on "class Profiler" and confirm us this exists only one in your MediaWiki directory tree?
