User:Pathoschild/2015 sul rename confusion
Appearance
Are you worried your account will be renamed?
- Check your global account status to make sure you're fully unified.
- Another account that redirects to yours might be renamed. Search this list for your user name to find accounts that redirect to your talk page, and check their global account status.
Still confused? Post a message on User talk:Keegan (WMF) and we'll help!
As part of the 2015 SUL unification, local users who will be renamed due to a name collision were notified on their talk page. Unfortunately the bot that delivered the message followed redirects, which means many users were notified of a pending rename to their global account instead of their secondary local account. This has caused much confusion and tumult.
Affected users
[edit]See:
- page 1: afwiki to elwiktionary (1413 users)
- page 2: enwiki to enwiktionary (660 users)
- page 3: eowiki to zh-yuewiki (2629 users)
Query
[edit]Assumptions
[edit]The query below reconstructs the list of affected users based on the following assumptions:
- If a user received a message from User:MediaWiki message delivery with the edit summary "Your account will be renamed" (or translated variants), they were notified about a SUL rename for their account.
- If that user's status before March 2015 was...
- detached: they are not affected even if the bot followed a redirect to their talk page. (The message applies to them anyway.)
- unified: they are affected if there's an incoming redirect from a detached user's talk page on the same wiki.
The list does not include these edge cases:
- Users affected due to a chain of three+ redirects where the second redirect is a detached account (e.g., detached user → detached user → unified user). User:MediaWiki message delivery will post on the second redirect page, so it won't be detected per assumption #2 (notified user isn't unified).
- Users affected due to an interwiki redirect (e.g. detached user@enwiki → unified user@metawiki). User:MediaWiki message delivery will ignore the redirect, so it won't be detected per assumption #2 (notified user isn't unified).
