Deprecation: #95037 - rootUid related setting of trees 

Description 

The setting rootUid used in FormEngine's treeConfig is superseded by startingPoints and has been marked as deprecated.

In \TYPO3\CMS\Core\Tree\TableConfiguration\DatabaseTreeDataProvider the following methods have been marked as deprecated:

• setRootUid()
• getRootUid()

Impact 

Using treeConfig/rootUid in TCA will trigger a TCA migration to treeConfig/startingPoints and raise a PHP E_USER_DEPRECATED error.

The same applies to the according page TSconfig option.

The extension scanner detects any call to setRootUid() or getRootUid() as weak match.

Affected Installations 

All extensions defining rootUid in their TCA or TSconfig are affected. Furthermore all extensions directly calling one of the mentioned methods in \TYPO3\CMS\Core\Tree\TableConfiguration\DatabaseTreeDataProvider .

Migration 

The setting treeConfig/rootUid can be migrated to treeConfig/startingPoints passing the value as string, since treeConfig/startingPoints takes a comma-separated value. The methods setRootUid() and getRootUid() can be replaced by their successors setStartingPoints() and getStartingPoints().
