It is not updated by purpose - see r13413. Introducing some better indexes for
this table instead of disabling the updates may be better, though.

Note that RenameUser can now be configured to update this table; the default for
this option is the same as $wgMiserMode, so on sites where expensive operations
are switched off, so will archive table updates be. This can be overridden, of
course.

There is no usertext index on the archive table, so renaming deleted edits
would be a performance issue.

Why can't we just add such an index? Surely archive is vastly smaller than revision.

Adding an index would enable my deletecontributions extension too :)

I.e., "schema updates are disruptive". Well, yeah. :) It can still be put in line with the other updates. And it's not like rev_deleted is going to instantly phase out the archive table in the next month or something.

• Zscout370 deleted own talk page over "HD DVD code pasted there several times"

which has been overnighted out by now probably

• User:Cool_Cat has some of User:White_Cat's contributions now:

I believe this is a bug. Deleted edits do not seem to be properly "renamed". It
may be unique to the case so additional review is necessary.

No it's not. The issue is known and the exact solution necessary is known. An index has to be added to the appropriate column of the archive table and the code has to be updated accordingly. Go bother Tim or someone about adding that index if you want.

As with enabled deletedcontribs extension, will wait until schema change done.

This is an active bug; the schema change is a dependency. The bug is not resolved until the schema change is done and all relevant code is updated.

Done in r23915.

Is this really fixed? Cause my edits are still attributed to my former username:

http://en.wikipedia.org/w/index.php?title=Special:Contributions&target=Cool%20Cat

It is fixed, but for renames from now on.
Although now that it's indexed, shouldn't be hard to do old renamings on request.

I see, can all past renames be processed? This is particularly important for licensing related reasons among other things.
