Deprecation: #84289 - Use ServerRequestInterface in File/CreateFolderController

See Issue #84289

Description

A series of class properties has been set to protected. They will throw deprecation warnings if called public from outside:

  • $number
  • $folderNumber
  • $target
  • [not scanned] $title
  • [not scanned] $returnUrl
  • $content

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] main()

Impact

Calling one of the above methods or accessing one of the above properties on an instance of CreateFolderController will throw a deprecation warning in v9 and a PHP fatal in v10.

Affected Installations

The extension scanner will find most usages, but may also find some false positives. The most common property and method names like $title are not registered and will not be found if an extension uses that on an instance of CreateFolderController . In general all extensions that set properties or call methods except mainAction() are affected.

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.
