Mit TYPO3 8.0 hat sich bei CLI Skripten eine Kleinigkeit geändert. Die Konstante TYPO3_cliMode ist fortan undefiniert. Mich hatte es eine Weile gekostet, bis ich drauf kam, warum mein CLI-Aufruf stets mit einem „Access denied“ starb. Mit der richtigen Suche findet sich in der Changelog-Doku dann aber des Rätsels Lösung:

==========================================
Breaking: #72368 - TYPO3 Constants removed
==========================================

Description
===========

The PHP constants ``TYPO3_enterInstallScript`` and ``TYPO3_cliMode`` and the global variable ``$GLOBALS['TYPO3_AJAX']`` which were used when a TYPO3 Request was initialized have been removed. They have been replaced by an alternative to use the ``TYPO3_REQUESTTYPE`` constant at the very beginning of each TYPO3 request.


Impact
======

Checking for the mentioned constants and global variable have no effect anymore and may lead to unexpected behaviour.

If not checked if the constant even was defined, the application will stop immediately.


Affected Installations
======================

Any installation which uses a third-party extension using these constants.


Migration
=========

Use ``TYPO3_REQUESTTYPE & TYPO3_REQUESTTYPE_CLI`` or ``TYPO3_REQUESTTYPE & TYPO3_REQUESTTYPE_INSTALL`` instead.
