Description

THere exists dozens of redirects MOS:FOO in siwiki, but because of mos: interwiki (T363538) they are unaccessible - no way to purge and probably also delete them

I suspect I may have accidentally conflated siwiki and slwiki when working on T363538

The options are:

  1. Create a "MOS:" namespace on the wiki to shadow the interwiki and run namespaceDupes to move them to that namespace
  2. Run cleanupTitles without creating a namespace, which will make the pages accessible at strange titles like Broken/MOS:FOO, and then deal with them locally somehow, while having MOS: remain an interwiki.

Which do you want?

Lee subscribed.Jan 12 2026, 3:24 PM

Option #1 (Create a "MOS:" namespace), sounds clean and easy isn't it?

Pppery added a comment.Jan 13 2026, 5:10 AM

It's clean and easy in one sense, but it leaves an extra namespace languishing on the wiki forever in another sense. The question is whether your wiki cares about links to "MOS:FOO" pages working, as opposed to just wanting to get the unreachable pages off of database reports and properly deleted.

Lee added a comment.Jan 13 2026, 4:05 PM

Well, most of the time we go along with what English Wikipedia does. Sooner or later our guys will ask for this namespace as well. I'm sure it will be something positive for our project.

Looks good!

It looks like that didn't do what it was supposed to and moved pages to "MOS-foo" instead of moving them into the new namespace. @Lee (or anyone else) you can clean it up on-wiki using the ordinary Special:MovePage feature.
