Breaking: #96291 - Disallow DB connection before TCA is loaded¶
See forge#96291
Description¶
Accessing the database API before TCA is loaded is considered to be a logic mistake, as TCA is required to generate the expected database schema.
Impact¶
Extensions that access the TYPO3 database API in
ext_localconf.php
files or TCA files will not work
any more, because TYPO3 will throw an exception in this case.
Affected Installations¶
TYPO3 installations with third-party extensions, that access database API before TCA is loaded.
Migration¶
Database API can be accessed earliest in the
\TYPO3\CMS\Core\Core\Event\BootCompletedEvent
.
