Important: #94280 - Move contents of ext_*.php into global namespace¶

Description¶

When warming up caches, the code of the files ext_localconf.php and ext_tables.php are now scoped into the global namespace.

Warning

The content of such ext_*.php files must not be wrapped in a local namespace by extension authors. This will result in nested namespaces and therefore cause PHP errors only solvable by clearing the caches via Install Tool!

Example code from the cache file:

/**
 * Extension: frontend
 * File: /var/www/html/public/typo3/sysext/frontend/ext_localconf.php
 */

namespace {
    // Content of EXT:frontend/ext_localconf.php
}

Having a namespace allows extension authors to import classes by the keyword use.

Example ext_localconf.php:

<?php

use TYPO3\CMS\Core\Utility\ExtensionManagementUtility;

defined('TYPO3') or die();

ExtensionManagementUtility::addUserTSConfig('
    options.saveDocView = 1
    options.saveDocNew = 1
    options.saveDocNew.pages = 0
    options.saveDocNew.sys_file = 0
    options.saveDocNew.sys_file_metadata = 0
    options.disableDelete.sys_file = 1
');
