      I do not really know what to test here:

      1/ configure opcache
      2/ try install, upgrade, etc.
      3/ run phpunit tests
      4/ test web services
      5/ do whatever else

      Maybe it would be best if every HQ developer installed opcache and used it for master development.

      Note: you can disable the opcache easily in your moodle config.php using (you can not enable it there!)

      ini_set('opcache.enable', 0);

    Description

      http://php.net/manual/en/book.opcache.php

      We need:

      • documentation
      • required + recommended settings
      • automatic reset and disabling

      Why? Because that is the only officially supported opcode cache in PHP 5.5.x (and even earlier versions via PECL).

      php.ini settings:

      [opcache]
      		 
      opcache.enable = 1
      		 
      opcache.memory_consumption = 128
      		 
      opcache.max_accelerated_files = 4000
      		 
      opcache.revalidate_freq = 60
      		 
       
      		 
      ; Required for Moodle
      		 
      opcache.use_cwd = 1
      		 
      opcache.validate_timestamps = 1
      		 
      opcache.save_comments = 1
      		 
      opcache.enable_file_override = 0
      		 
       
      		 
      ; If something does not work in Moodle
      		 
      ;opcache.revalidate_path = 1 ; May fix problems with include paths
      		 
       
      		 
      ; Experimental for Moodle 2.6 and later
      		 
      ;opcache.fast_shutdown = 1
      		 
      ;opcache.enable_cli = 1 ; Speeds up CLI cron
      		 
      ;opcache.load_comments = 0 ; May lower memory use, might not be compatible with addons and other apps.
