.. include:: /Includes.rst.txt .. _deprecation-94313: =========================================== Deprecation: #94313 - AbstractService class =========================================== See :issue:`94313` Description =========== The :php:`TYPO3\CMS\Core\Service\AbstractService` class is part of the ancient :ref:`Service API `. This API did not really prevail, except it's usage for the authentication process. Since the authentication service related functionality was already decoupled over the last years, the :php:`AbstractService` got finally unused in Core since :issue:`88646`. Therefore it has now been marked as deprecated. Impact ====== Extending this class does *not* raise a deprecation error level log entry. The class contains only a `@deprecated` class annotation. Extension classes can still extend this class in v11 without impact, it will raise a PHP fatal error in v12, when the class is dropped. Affected Installations ====================== As mentioned, the Service API never found many usages in casual extensions. It is therefore pretty unlikely that well maintained projects are affected. The extension scanner will find any class usages as a strong match. Migration ========= Remove any usage of this class in your extension. In case you currently extend :php:`AbstractService` for use in an authentication service, which might be the most common scenario, you have to change your service class to extend from :php:`AbstractAuthenticationService` instead. In case you currently extend :php:`AbstractService` for another kind of service, which is rather unlikely, you have to implement the necessary methods in your service class yourself. Please see `Service Implementation `__ for more details about the required methods. However, even better would be to completely migrate away from the Service API (look for :php:`GeneralUtility::makeInstanceService()`), since the Core will deprecate these related methods as well. .. index:: PHP-API, FullyScanned, ext:core
