Deprecation: #84369 - Protected methods and properties in UserSettingsController 

See forge#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.
