Deprecation: #109523 - GeneralUtility::isOnCurrentHost() without PSR-7 request 

Description 

Calling \TYPO3\CMS\Core\Utility\GeneralUtility::isOnCurrentHost() without providing a PSR-7 \Psr\Http\Message\ServerRequestInterface as the second argument is deprecated.

The method previously resolved the current host via \TYPO3\CMS\Core\Utility\GeneralUtility::getIndpEnv(), which hides an implicit dependency on server globals. The method signature has been extended to accept an explicit PSR-7 request object, which should be passed instead.

Impact 

A PHP E_USER_DEPRECATED error is triggered when \TYPO3\CMS\Core\Utility\GeneralUtility::isOnCurrentHost() is called without a \ServerRequestInterface argument.

Affected installations 

All installations with third-party extensions that call \TYPO3\CMS\Core\Utility\GeneralUtility::isOnCurrentHost() with only one argument.

Migration 

Pass the current PSR-7 request as the second argument to \TYPO3\CMS\Core\Utility\GeneralUtility::isOnCurrentHost().

Before:

use TYPO3\CMS\Core\Utility\GeneralUtility;

$isOnCurrentHost = GeneralUtility::isOnCurrentHost($url);

After:

use Psr\Http\Message\ServerRequestInterface;
use TYPO3\CMS\Core\Utility\GeneralUtility;

$isOnCurrentHost = GeneralUtility::isOnCurrentHost($url, $request);

The PSR-7 request is available in various places, for example as an argument in controller actions, via $GLOBALS['TYPO3_REQUEST'] in legacy contexts, and via \ServerRequestInterface method parameters.
