File opcache-default.blacklist of Package php
; The blacklist file is a text file that holds the names of files
; that should not be accelerated. The file format is to add each filename
; to a new line. The filename may be a full path or just a file prefix
; (i.e., /var/www/x blacklists all the files and directories in /var/www
; that start with 'x'). Line starting with a ; are ignored (comments).
; Files are usually triggered by one of the following three reasons:
; 1) Directories that contain auto generated code, like Smarty or ZFW cache.
; 2) Code that does not work well when accelerated, due to some delayed
; compile time evaluation.
; 3) Code that triggers an OPcache bug.
