Description:
Consider the following database, which we would like to install MediaWiki onto:
mysql> show tables;
+----------------------------------------------+
| Tables_in_wizard_test_mediawiki_install_head |
+----------------------------------------------+
| user |
+----------------------------------------------+
1 row in set (0.00 sec)
There's a single user table here, ostensibly left over from a failed install. OK, that's fine. How does the installer cope? It claims "config-install-tables-exist", and then cheerfully attempts to access 'interwiki' table, which doesn't exist.
Ironically, the user table is unconditionally created.
Ideally, DatabaseInstaller->createTables should sanity check the existing tables and error out with something more reasonable if they don't match up with the schema, or complain that you should rather be using the ugprader.
You can treat this as a feature request. Probably.
