Page history merge Simple.png

Shortcut: COM:HMS · COM:HISTMERGE This page provides information on issues and solutions relating pages and files that underwent cut-and-paste moves (which its history has to be put back together), and inappropriate merging/overwriting (of which its history needs to be split).


History merging

Because most users have the ability to use the move page function, cut-and-paste moves are usually done by people who are not aware of that function, or when the move function fails (e.g. because the target has history), and people who aren't aware of the Administrators Noticeboard forum to ask for help from an administrator.

When a cut-and-paste move is done, the page history of a page can be split among two or more different pages. This is very undesirable, because we need to keep the history with the content for copyright reasons. In most circumstances, administrators are able to fix this by merging page histories.

Instruções para administradores
  1. Temporariamente apague PáginaNova
  2. Mova PáginaAntiga para PáginaNova, usando a funcionalidade de mover. [Num caso de um arquivo, você deve abrir o link Mover & Substituir numa nova janela ou desativar AjaxQuickDelete nas suas preferências.] (Agora versões antigas são o total do histórico do título novo)
  3. Restaure a página PáginaNova, ao
    1. Ver o histórico da página/arquivo
    2. Clicar "Ver ou restaurar ... edições apagadas", e
    3. Clicking on “Restore!”. (Now the new title’s history has both the old and new versions, including an extra copy of the most recent version of OldPage, created by the move tool.)
  4. At this stage, NewPage will only show the text “#REDIRECT NewPage” (assuming a redirect was the most recent version of OldPage, the NewPage page will now be showing whatever the most recent version of OldPage was). The last step is to revert (or RevisionDelete) to the last version of NewPage from before the move.

Special:MergeHistory makes it possible to automatically merge the history of two pages.

History splitting

Over time, pages or files may change from one underlying topic to a completely separate topic. Normally, this should be accomplished through moves of pages, or by reuploading an altered file on a slightly different title. However, if a user is unfamiliar with those processes they may simply change the subject of a page or file (overwriting the old). If this is not caught immediately it is very easy for the new topic to build up a substantial edit history of its own.

Instructions for admins
  1. Temporarily delete the page/file (original title)
  2. Restore previous revisions up to (but not including) the point where the topic was changed.
  3. Move (without redirect) the restored versions (old topic) to the desired new title. (In case it is a file, you have to open the Move & Replace link in a new tab or disable AjaxQuickDelete in your preferences.)
    • If there’s already a file or page under the new title and you wish to histmerge into it:
    a) select the “delete the existing article” option, while moving;
    b) restore deleted revisions of new title.
  4. Restore new revisions of new topic (still at original title).

A history merge could also be undone in this way.

Requesting a merge or split

To request a merge or split, fill the following template, and submit it at the bottom of this page. Remember, both files need to be of the same type. Merging of more than two files may also be possible in some cases.

== [[:FILE/PAGE 1]] → [[:FILE/PAGE 2]] ==
* Request: [Split or Merge]
* Reason:
  • For merges, replace FILE/PAGE 2 with the page you want FILE/PAGE 1 contents to be merged into.
  • For splits, replace FILE/PAGE 2 with the new filename which you want the newer content to be moved from FILE/PAGE 1.

Double image merge

File:Kunstwerk metrostation Bizet 1992.jpg and File:Metro Brussel decoratie.jpg are the same, only 'Metro Brussel decoratie' is bigger. They are different scans from the same slide and I didn't notice until to late. The largest scan should remain but preferabaly under the name of 'Kunstwerk metrostation Bizet 1992'. I would like to move the image from 'Metro Brussel decoratie' to 'Kunstwerk metrostation Bizet 1992' and overwrite. As end result only 'Kunstwerk metrostation Bizet 1992' should remain with to versions. ik people want to use the smaller scan they stil can. Description and categories are already synchronized.Smiley.toerist (talk) 12:25, 10 May 2019 (UTC)

In other words (correct me if I’m wrong, Smiley.toerist), merge File:Metro Brussel decoratie.jpg into File:Kunstwerk metrostation Bizet 1992.jpg, but afterwards revert to the bigger file version if necessary. The last step you could also do on your own after merging, Smilie.toerist. — Speravir – 20:55, 17 May 2019 (UTC)

  • Request: Merge
  • Reason: Image #1 is simply an updated version of image #2. Image #2 should just be updated with a new version.

File:BogdanovBelsky UstnySchet.jpgFile:Bogdanov-Belsky Ustny Schet (Tretyakov).jpg

Please, split only the most recent version from the others. I think, both versions are too different, but could exist on their own. The older versions are too small, though. I would afterwards fix necessary things.
