Deprecation: #94394 - Extbase Request setDispatched() and isDispatched()

See Issue #94394

Description

To further prepare towards PSR-7 requests in Extbase, the two methods TYPO3\CMS\Extbase\Mvc\Request->setDispatched() and TYPO3\CMS\Extbase\Mvc\Request->isDispatched() have been marked as deprecated.

Impact

Using the methods is discouraged. The Extbase dispatcher still recognizes them and acts accordingly, the methods do not raise a deprecation level log entry, though.

Affected Installations

Some Extbase based extensions may use setDispatched(), but it’s rather unlikely since that flag has been mostly used internally through existing helper methods in Extbase controllers.

The extension scanner will find possible candidates.

Migration

Action dispatching in Extbase now depends on the returned response:

  • A casual 2xx Response from a controller action that for instance contains HTML or Json stops Extbase dispatching, the response is later returned to the client.
  • An Extbase ForwardResponse instructs the dispatcher to dispatch internally to another controller action.
  • A 3xx RedirectResponse stops dispatching and is returned to the client to initiate some client redirect.
