Bug #71292 [Opn->Fbk]: Opcache settings have no effect, only default settings are loaded

Edit report at https://bugs.php.net/bug.php?id=71292&edit=1 ID: 71292 Updated by: ab@php.net Reported by: dev at models dot com Summary: Opcache settings have no effect, only default settings are loaded -Status: Open +Status: Feedback Type: Bug Package: opcache Operating System: Windows Server 2008 R2 / IIS PHP Version: 7.0.1 Block user comment: N Private report: N New Comment: Thanks for the report. Yes, it is the know issue that sometimes reattaching to SHM fails. In 7.0 the INI directive opcache.file_cache_fallback was added, to still make use of the file cache in this situation. In your configuration, opcache.file_cache= has no value, thus the fallback cannot work. Please set a valid path as a value and observe the happenings. Thanks.

Which seems to be the same issue or related to the one described here: https://github.com/zendtech/ZendOptimizerPlus/issues/167 and in this php bug report: https://bugs.php.net/bug.php?id=64926 ------------------------------------------------------------------------ [2016-01-05 20:22:10] dev at models dot com Description: ------------ Changing any of the opcache. settings after having enabled the extension in php.ini has no effect on any of the settings. The only thing that seems to work is loading or unloading the opcache extension adding or removing the zend_extension="full path to opcache dll" option. Opcache is enabled and loaded, verified via phpinfo() which reports that the opcache module is loaded and enabled. This is on Windows Server 2008 R2, running php 7.0.1 x64 nts in fastcgi mode. Making the same changes on php 5.5.29 on the same server works properly, opcache settings can be changed via php.ini and new settings are reported by phpinfo().
