Deprecation: #99650 - Global Request object usage in Extbase UriBuilder

See forge#99650

Description

Usage of the global request object ( $GLOBALS['TYPO3_REQUEST']) as fallback in the EXT:extbase \TYPO3\CMS\Extbase\Mvc\Web\Routing\UriBuilder has been deprecated and will be removed in TYPO3 v13. The UriBuilder will then solely rely on a locally set request object.

Impact

Using the UriBuilder class of Extbase without a local request object will trigger a PHP deprecation warning.

Additionally, when using the UriBuilder to build frontend URLs, the current content object is required. It is initialized from the handed in local request object. This means, in case extensions do set the request object, a automatic fallback is applied in v12, triggering a PHP deprecation warning, as it will be removed in v13, too.

Affected installations

TYPO3 installations with custom extensions initializing the UriBuilder without handing in a request object and using it to build URIs.

Migration

Make sure to call setRequest($request) before using the UriBuilder, when no other component has done this already.

Using ViewHelpers will not trigger the warning, as the TYPO3 Core ensures the proper setup.
