=====================================================================
|
|
Deprecation: #85793 - Several constants from SystemEnvironmentBuilder
|
|
=====================================================================
|
|
|
|
See :issue:`85793`
|
|
|
|
Description
|
|
===========
|
|
|
|
The following constants have been deprecated and should not be used any longer:
|
|
|
|
* :php:`NUL` (Use :php:`"\0"` instead)
|
|
|
|
* :php:`TAB` (Use :php:`"\t"` instead)
|
|
|
|
* :php:`SUB` (Use :php:`chr(26)` instead)
|
|
|
|
* :php:`TYPO3_URL_MAILINGLISTS`
|
|
|
|
* :php:`TYPO3_URL_DOCUMENTATION`
|
|
|
|
* :php:`TYPO3_URL_DOCUMENTATION_TSREF`
|
|
|
|
* :php:`TYPO3_URL_DOCUMENTATION_TSCONFIG`
|
|
|
|
* :php:`TYPO3_URL_CONSULTANCY`
|
|
|
|
* :php:`TYPO3_URL_CONTRIBUTE`
|
|
|
|
* :php:`TYPO3_URL_SECURITY`
|
|
|
|
* :php:`TYPO3_URL_DOWNLOAD`
|
|
|
|
* :php:`TYPO3_URL_SYSTEMREQUIREMENTS`
|
|
|
|
|
|
Impact
|
|
======
|
|
|
|
The above constants are still defined in TYPO3 v9, but their definition will be
|
|
dropped in TYPO3 v10.
|
|
|
|
|
|
Affected Installations
|
|
======================
|
|
|
|
Constants can not be deprecated as such and using them does not trigger a PHP :php:`E_USER_DEPRECATED` error.
|
|
Extensions in TYPO3 v9 should not use them any longer but switch to the alternatives already.
|
|
|
|
The extension scanner will find usages of the above constants and marks them as strong
|
|
matches.
|
|
|
|
|
|
Migration
|
|
=========
|
|
|
|
Use one of the :php:`chr(*)` variants or replace the constant usage with the URL in your own code.
