Joomla resetting PHP opCache with phar packages
Posted: Mon Dec 26, 2022 2:39 pm
Hi,
After updating to 3.9.10, we noticed greatly increased CPU utilization in our application. After a lot of investigation, we found that including a PHP Phar package caused the PHP opcache to get reset on every request.
Since that phar package (for geoip) was included in pretty much every request, the opcache was getting constantly reset.
We narrowed it down to this call:
\TYPO3\PharStreamWrapper\Helper::resetOpCache
in /libraries/vendor/typo3/phar-stream-wrapper/src/PharStreamWrapper.php
That logic was triggered by this call in our application.
require 'geoip2.phar';
Changing the phar include over to a composer require solved the problem, but the resetOpCache in Typeo3 is deadly.
