TYPO3 Core

How to reproduce¶

1. Grab a remote database dump containing a view different from local DB user (e.g., whose definer is "root@%" whereas locally you'll have "typo3_localsite").
2. Restore the dump into your local database
3. Go to install tool (/typo3/install)

You are now stuck on step "Create user and import base data" because \TYPO3\CMS\Core\Database\DatabaseConnection::admin_get_tables() is unable to fetch tables due to this VIEW which you are not allowed to access (and which has nothing to do with any TYPO3 requirements).

Possible solution¶

Make \TYPO3\CMS\Install\Controller\Action\Step\DatabaseData::needsExecution() have a more targeted condition.
