List of steps to reproduce (step by step, including full links if applicable):
- Update an interwiki on the interwiki table of the database
- Run maintenance/clearInterwikiCache.php to clear the interwiki cache (otherwise the change is not visible on pages)
The script outputs nothing. The interwiki cache is not cleared.
What should have happened instead?:
The interwiki cache should have been cleared,
Looking at the source code, the script iterates through $wgLocalDatabases, which normally it's not set (defaults to an empty array). For each entry in $wgLocalDatabases it should print the wiki id. In my wiki this setting is untouched and hence empty.
It should have cleared the interwiki cache of the current wiki if $wgLocalDatabases is not set.
