Deprecation: #84324 - Use ServerRequestInterface in File/FileController¶
See Issue #84324
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:
Calling one of the above methods on an instance of
FileController will throw a deprecation warning in v9 and a PHP fatal in v10.
The extension scanner will find most usages, but may also find some false positives. In general all extensions
that call methods except
mainAction() are affected.
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.
