Deprecation: #94979 - Using CacheManager or Database Connections during TYPO3 bootstrap¶
See forge#94979
Description¶
TYPO3 now triggers a PHP E_USER_DEPRECATED error if extension authors
or site admins have code in their ext_localconf.php,
Configuration/TCA/* configuration files or ext_tables.php, that
calls the \TYPO3\CMS\Core\Cache\CacheManager or interacts with the database.
This is important for extension authors as TYPO3 will become stricter in the future in terms of booting up TYPO3's Core Configuration, making typical requests much faster, as all configuration can be cached away. When using TYPO3 in a build environment, this will also lead to possibilities to pre-warmup caches during the build phase of a new deployment.
Impact¶
Accessing the database and utilizing the Cache Manager in
these files will trigger a PHP E_USER_DEPRECATED error.
Affected Installations¶
TYPO3 installations with extensions using Cache Manager or Database Connections in their configuration files (see above).
Migration¶
Use proper places to initialize extensions, and only when needed to reduce the general time to boot up TYPO3's configuration.
