Deprecation: #83976 - Moved file extension detection to FAL driver

See forge#83976


The only object that is allowed to handle the physical file in the FAL is the driver, as it is the only instance that knows how to access the file.

The definition of the FAL driver method getFileInfoByIdentifier() is enhanced with the return value extension.


Installations with a FAL driver getFileInfoByIdentifier() method that doesn't return the extension value will trigger a PHP E_USER_DEPRECATED error.

Affected Installations

Installations with 3rd party FAL drivers.


Adjust the getFileInfoByIdentifier() method of your file drivers to return the extension value.
