Feature: #92562 - Frontend groups resolved directly after the Frontend User itself
|
|
==================================================================================
|
|
|
|
See :issue:`92562`
|
|
|
|
Description
|
|
===========
|
|
|
|
For legacy purposes, the valid frontend user groups were added while resolving
|
|
the root line in TypoScriptFrontendController. This is much later in the frontend
|
|
request process than the preparation of the Frontend User, which is resolved by
|
|
the session or form credentials.
|
|
|
|
There are several reasons for the historic behavior:
|
|
|
|
* Special functionality like "pages.fe_login_mode" which can override groups based on the current root line
|
|
* Previewing frontend user groups via the Admin Panel for backend users
|
|
|
|
However, this historic behavior led to inconsistencies, especially with the
|
|
Context API to retrieve the correct usergroups in PSR-15 middlewares to build custom APIs.
|
|
|
|
In addition, this functionality is now extracted from TSFE and into the middleware,
|
|
further decoupling the User authentication from the TSFE object.
|
|
|
|
|
|
Impact
|
|
======
|
|
|
|
When the PSR-15 middleware is setting up the FrontendUserAuthentication object
|
|
at a very early stage of the frontend request, the groups are resolved directly
|
|
afterwards, leaving the FrontendUserAuthentication object in a consistent state
|
|
for further middlewares to work with the appropriate groups.
|
|
|
|
Please note that any existing custom AuthenticationService for resolving frontend
|
|
user groups, which might rely on a valid TSFE object will have to be evaluated
|
|
if it still works in TYPO3 v11.
|
|
|
|
Also: Further middlewares and TSFE itself can still override the assigned groups
|
|
due to previewing behavior.
