TYPO3 Core

Background¶

• Loaded a 7.6 DB dump and all files locally
• Replaced typo3_src with master branch
• Went to /typo3/install

Steps to reproduce¶

• In the install tool, click on "Upgrade Wizard" menu
• It crashes with:

Cause¶

• PHP Fatal error is thrown in \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::loadSingleExtTablesFiles:1881 with

require $extensionInformation['ext_tables.php'];

• This could be prevented or catched and rethrown with e.g., the $_EXTKEY using a catch (\Error $e) since PHP7
• Underlying faulty extension is EXT:gridelements, because of this call:

// Register backend_layout wizard
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addModulePath(
        'wizard_gridelements_backend_layout',
        \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::extPath($_EXTKEY) . 'Classes/Wizard/'
);
