This sort of change usually requires community consensus at the wiki in question.

Right, please show community consensus. [[WP:CON]]

Generally the way duplicates are handled (by namespaceDupes.php) is that one of the dupes is automatically renamed to [[original_name/BROKEN]], from there the community usually deletes or renames as appropriate.

Very well. Then I have only two questions:

1. Will these renamings be logged anywhere to let us handle them?
2. Am I supposed to do anything else if the community has no objections for now?

Generally the renames will be listed on the bug report after the request is done (or at least that's what has happened for other similar requests). If the community has no objections, then there is nothing else you have to do. Note, that sometimes these requests take a little while to fulfill, as often the shell users wait until there are several shell requests, and then do them all at once.

If your question is about the formal subsection with a summary by an uninvolved administrator, it wasn't closed this way as you can see. After some active users agreed to the suggestion, I announced it right on Bugzilla asking about possible fallout. Then I posted a link to this bug so that everyone could express their opinion or concerns here and get a response from a technical point of view. However, nobody had any questions nor did anyone contribute to the local discussion after my last post. Therefore I think the consensus for the adjustment has been reached, since no objections were raised throughout the talk (apart from possible breaks in similarly named pages, which, as explained above, will be visible and amendable immediately).

change?

Yes, this can be done.

Done

Are you sure? I still don't see [[ВП:Кнайпа]] redirect to [[Вікіпедія:Кнайпа]]. Perhaps it needs some time to be fulfilled or you chose incorrect namings?

Looks like ВЦ: has been redirected instead of ВП:, but this prefix works properly. Fix it please.

microcell3 wrote:

There's only one letter which needs changing in the code. No problems occur with using ВЦ: as the alias, but it's incorrect and doesn't match existing shortcuts. Please, do this small change so that we could ask additional questions in case something goes wrong.

Just tried to push this for you, but there are some sync-script problems

Will deal with it later for you

Thank you for addressing the issue, it seems to work now but caused another glitch. All pages starting with "ВП:" which belonged to the mainspace before, instead of moving to another namespace disappeared along with edit histories. Shall we recreate them all by hand or this is just what's gonna be fixed later?

It looks like it might've actually merged out, and is somewhat lying to me.

I don't think it is fully done.

Give me a couple of hours till the people are at work in the WMF office, I'll get the script run, and run namespaceDupes.php for you, and that'll tidy up the missing pages etc

Most of them should be fixed now, but getting the following errors still

Want the alias disabling while those pages are fixed?

Yes, that works, thanks for a quick response. As to those pages, their titles coincide everywhere, thus the reader is unlikely to notice the update anyhow. So I think nothing else must be done about them.

I've run

php namespaceDupes.php ukwiki --fix --suffix=/FIXME

which moves all unfixable pages to ''old pagetitle''/FIXME. Unfortunately, my terminal was set to latin1 instead of UTF8, so that I can't show the screen output.
