Deprecation: #84369 - Protected methods and properties in UserSettingsController

See Issue #84369

Description

This file is about third party usage (consumer that call the class as well as signals or hooks depending on it) of TYPO3\CMS\Backend\Controller\UserSettingsController.

All methods not used as entry points by TYPO3\CMS\Backend\Http\RouteDispatcher will be removed or set to protected in v10 and throw deprecation warnings if used from a third party:

  • [not scanned] process()

Impact

Calling above method on an instance of UserSettingsController will throw a deprecation warning in v9 and a PHP fatal in v10.

Affected Installations

The extension scanner will find all usages, but may also find some false positives.

Migration

In general, extensions should not instantiate and re-use controllers of the core. Existing usages should be rewritten to be free of calls like these.
