Two different usernames[edit]

I got the renaming announcement for an account I didn't even remember I have. My global account is en:User:Radulfr and the other one is wikibooks:fi:User:Radwulf. Can they be merged somehow? I do remember the password for both accounts. Radulfr (talk) 13:07, 18 March 2015 (UTC)

@Radulfr: An account merge tool has been developed but unfortunately it needs further bug fixing. We expect it to be ready in about six weeks. Please drop us a note in two months where both accounts confirm the merge action. Cheers, —DerHexer (Talk) 17:16, 18 March 2015 (UTC)
Great, thanks. Radulfr (talk) 17:46, 18 March 2015 (UTC)
@DerHexer: Any update on this? Years ago I accidentally made two accounts (CFynn on Wikipedia and Cfynn on Commons) which are both global and have been wanting to merge them (to CFynn) for a long time. Cfynn (talk) 07:20, 19 September 2015 (UTC)
@Cfynn: The tool will be delayed for months and it's not yet clear if we will ever get an account merge tool. My suggestion would be to have Cfynn@commonswiki renamed to CFynn. Therefore, I had to rename CFynn@commonswiki to a temporary name like CFynn (usurped). Its 168 edits wouldn't be connected with your global account (nor the 333 edits on enwiki) but you would have CFynn@enwiki and Cfynn@commonswiki combined which would stongly reduce the number of login changes.

User:DerHexer: So are stewards now willing to make local renames? Back in May, I was told that I would have to wait for a few more week until the merging extension becomes available. If possible, could you please rename Stefan4@commonswiki into Stefan2@commonswiki? It would simplify things a lot for me if I won't need to log in and log out all of the time when switching from one project to another. --Stefan2 (talk) 22:42, 12 October 2015 (UTC)
@Stefan2: Sure, please confirm with Stefan4 and I will proceed under the supervision of a developer as you have more than 50'000 edits which is a limit for us. Cheers, —DerHexer (Talk) 22:54, 12 October 2015 (UTC)
Confirmed. Also note that there already was a confirmation on the other page I linked to. --Stefan4 (talk) 23:07, 12 October 2015 (UTC)
User:DerHexer: Any schedule for when the account can be renamed? --Stefan2 (talk) 10:40, 15 October 2015 (UTC)
@Stefan2 and Stefan4: Sorry, I didn't see your message without the ping. I will be in San Francisco the next days for a steward meeting which will take place from Oct 21 to 23. Within these days, we can rename your account. I will ping you when we start, okay? Cheers, —DerHexer (Talk) 14:12, 16 October 2015 (UTC)
User:DerHexer: Wonderful! It will be very convenient to have the Commons account renamed as I won't have to log in and out all of the time when switching between Commons and Wikipedia. Have a nice time in the United States! --Stefan2 (talk) 11:25, 18 October 2015 (UTC)
@Stefan2 and Stefan4: I will proceed now soonish, be excited and please don't use the Wikimedia projects until I tell you. :D —DerHexer (Talk) 17:14, 23 October 2015 (UTC)
@Stefan2: You probably noticed that we had some problems with getting your account renamed. I failed twice so that a system administrator had to push it from shell. Afterwards I moved your userpages. Please go to Special:MergeAccount now, submit your password and get your account unified. Thank you and enjoy. :-) Cheers, —DerHexer (Talk) 04:40, 24 October 2015 (UTC)

Please merge accounts that have the same email address attached to them or allow users to merge them themselves if no email address has been attached yet. This gives a lot of duplicate accounts that will never be used again and edit history will get scattered amongst those accounts.

The former was done by the Wikimedia Foundation, the latter was recommended to the users (afaik). Cheers, —DerHexer (Talk) 17:16, 18 March 2015 (UTC)

I also have almost the same situation but I'm using the account ru:User:Rex that has to be renamed because it's not global. I have the global account ru:User:Alex Rex but I'm not using it now, just put a redirect in my native wiki. But if I have to rename my active account I'd better prefer merge it with my other empty global account. How can it be done? You're talking about six weeks but your announcement declares the deadline in this april. Can I be in time in this case? 07:46, 23 March 2015 (UTC)

Renames over imported edits' usernames[edit]

Hello, I'm not sure this is the proper place to mention it, but I will give it a try. I have noticed a bug on articles, that have been copied (with edit history) into another wiki and translated. I believe compatibility across wikis was one of the primamy aims of unified accounts. My example can be seen on this contributions link:äge/Andreas_Müller%7Edewiki. The edits from 2010 and onwards are actually mine, not Andreas Müller~dewiki's, but miscredited, because after the import of the Danish article into the German wiki, he was the one with my name on the German wiki, and the credit was automatically linked with his account. Is this something that can be looked at centrally (for example, checking and referencing usernames on the original wiki, if an article has been copied?). Many greetings and thanks for the good work with the unified logins! --Andreas Müller (talk) 08:33, 22 June 2015 (UTC)

This is a problem specific to, which for a while has had this terrible and legally redundant habit of duplicating revision information. That said, if you are right, it seems we had a bug with the import tool, because the rev_user is supposed to be 0, while it was assigned to the local user:
MariaDB [dewiki_p]> select rev_id, rev_user_text, rev_user from revision where rev_page = 7458434 and rev_user_text LIKE 'Andreas%';
| rev_id    | rev_user_text          | rev_user |
| 112370348 | Andreas Müller~dewiki  |    20718 |
| 112370349 | Andreas Müller~dewiki  |    20718 |
| 112370350 | Andreas Müller~dewiki  |    20718 |
| 112370351 | Andreas Müller~dewiki  |    20718 |

So it's not a CentralAuth/Renameuser bug, but a MediaWiki core bug. Past errors can't be fixed, hence you want phabricator:T20209. --Nemo 19:59, 23 June 2015 (UTC)
And how do you ensure a correct attribution in the edit summary? That's not possible at all. Besides, imports give much better statistics how articles have been created and how they developed. Finally, regardless what the WMF claims in its terms of use, in the end the license itself counts and that one requires much stricter attribution (at least in CC 3.0 licenses). Therefore, from now on the WMF should disallow non-imported wikitext copies as imports perfectly fulfill the licenses and are most often easily to do. Cheers, —DerHexer (Talk) 23:31, 25 June 2015 (UTC)
Terms of use were confirmed as consistent with the license by Creative Commons itself, so's interpretation is not supported by anything. --Nemo 10:55, 26 June 2015 (UTC)
To make sure the issue was not introduced by the rename, I checked the historical dump and confirmed that the revisions incorrectly had rev_user > 0 before the rename as well.

I reproduced the bug and filed it as phabricator:T112384. Sorry for the wait. --Nemo 15:12, 12 September 2015 (UTC)
