.. include:: /Includes.rst.txt .. _deprecation-85462: =========================================================== Deprecation: #85462 - Signal 'tablesDefinitionIsBeingBuilt' =========================================================== See :issue:`85462` Description =========== The usage of signal :php:`tablesDefinitionIsBeingBuilt` of class :php:`\TYPO3\CMS\Extensionmanager\Utility\InstallUtility` has been marked as deprecated and will be removed in TYPO3 v10. The signal is a duplication of :php:`tablesDefinitionIsBeingBuilt` of class :php:`\TYPO3\CMS\Install\Service\SqlExpectedSchemaService` that is now also emitted during extension installation. Impact ====== Slots of this signal will get executed in TYPO3 v9 but will be abandoned with TYPO3 v10. If a slot provides SQL definitions a PHP :php:`E_USER_DEPRECATED` error is triggered. Affected Installations ====================== Extensions that register slots for the signal :php:`tablesDefinitionIsBeingBuilt` of class :php:`\TYPO3\CMS\Extensionmanager\Utility\InstallUtility`. Migration ========= Extensions should use the signal :php:`tablesDefinitionIsBeingBuilt` of class :php:`\TYPO3\CMS\Install\Service\SqlExpectedSchemaService` instead which is now emitted during an extension installation. .. index:: Backend, LocalConfiguration, PHP-API, NotScanned, ext:extensionmanager
