Shortcuts: 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

[edit]
Shortcut

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.

Instructions for admins
  1. Temporarily delete NewPage
  2. Move OldPage to NewPage, using the move functionality. (In case it is a file, you have to open the Move & Replace link in a new tab or disable AjaxQuickDelete in your preferences.) (Now the old history versions are the whole of the new title’s.)
  3. Undelete the NewPage page, by:
    1. Viewing the page/file history
    2. Clicking “View or restore … deleted edits?”, and
    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

[edit]
Shortcut

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

[edit]

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.

First, this project page is not meant for categories. These can other than a manipulation of image history be edited by everyone.
Second, Category:The Family Channel (American TV network, founded 1990) is a sub category of Category:History of Freeform (TV channel) which is itself a sub category of Category:Freeform. Therefore, there is nothing to do here. — Speravir – 01:25, 2 June 2025 (UTC)[reply]

Probably a more complex one: Perhaps Split and Merge in two steps

[edit]

First some background: Subbass1 uploaded the original version of Satzkorn, Dorfkirche (02).jpg and requested about two years ago in dewiki some retouching, see archived thread (in German, of course): de:Wikipedia:Fotowerkstatt/Archiv/2023/Mai#Kanzelrest. There he wrote the image should be overwritten with the new version (in German slang: “bitte drüberladen”). Now for the complex part:
The version where a crop and rotation has been done is now the active version under the original name, but should perhaps better split from it. On the other hand, the version which is in the moment separated could be merged, because the image is visually unchanged outside of the retouching.

Easy approach:

Alternative approach:

  • Two steps:
  1. Split File:Satzkorn, Dorfkirche (02).jpg. The new version could be named File:Satzkorn, Dorfkirche (02) - cropped and rotated.jpg.
  2. Like “easy approach”: Merge File:Kanzelrest PSX 20230508 101614.jpg into File:Satzkorn, Dorfkirche (02).jpg (but now without the edited version), keep the latter (original) name.

A third approach would be doing the splitting step only. Then I would rename Kanzelrest PSX 20230508 101614.jpg myself which was my primary intention, but then I noticed what has happened. — Speravir – 23:43, 2 June 2025 (UTC)[reply]

Comment Does you have a reason for the file to justify the split? Just saying "please split" isn't really enough to justify the split of the file. Need more than a proof regarding the difference to versions to doing that. Yayan550 (talk) 22:22, 8 June 2025 (UTC)[reply]

File:Beetle 2015.jpg → File:Expo autos antiguos.jpg

[edit]
  • Request: Split replacement version
  • Reason: The original version (File:Beetle 2015.jpg) contains an actual 2015 Volkswagen "New" Beetle, and thus is more deserving of the name. The replacement (File:Expo autos antiguos.jpg) is of some vague non-descript antique American car show somewhere in Latin America and has no visible Volkswagen Beetles, new or old. The original photographer should know the exact location and give details and categories. I tried to zoom in on the license plates in order to find it myself, but they were too blurry. --DanTD (talk) 14:36, 7 June 2025 (UTC)[reply]
