Change Details

[Maintenance.php](https://github.com/wikimedia/mediawiki/blob/ee54ee6367d85b0d968d8a9faa7ebc75e3c6490c/maintenance/Maintenance.php#L1063) defines a constant MW_DB based on the --wiki parameter, but at least according to Github's search, MW_DB is not used elsewhere. I tried to run update.php using --wiki commonswiki (I confirmed that the database commonswiki existed): > > vagrant@mediawiki-vagrant:/vagrant/mediawiki/maintenance$ php update.php --wiki commonswiki > MediaWiki 1.27alpha Updater > > Your composer.lock file is up to date with current dependencies! > Going to run database updates for **wiki** Its supposed to print out which wiki it's running database updates for, but it always seems to print the default, 'wiki'.
