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).

Contents

History mergingEdit

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 splittingEdit

Shortcut
COM:SPLIT

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 splitEdit

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.

File:- panoramio (2965).jpgFile:Undetermined Beach in Crimea; August 2010Edit

  • Request: Split and rename original version.
  • Reason: Overwritten files:
    Evidently User:Panoramio upload bot uploaded two files with the same bad name and no description for either version. Despite the lack of a description, the image infobox is clearly better suited for the first version. This version by somebody named "Kailito" is at some beach in Crimea and was taken on August 23, 2010, as evidence suggests in the archive of the original photographer's Panoramio page . The second version which was taken on June 2, 2010, is by User:Idawriter, and is of an intersection containing a Turkey Hill gas station and convenience store, somewhere in Pennsylvania, which you can tell by the small signs across from this gas station (the ones with "SR 222/310" pointing one way and "SR 222/300" pointing another). In time, both versions should get a proper name, but since the one from Pennsylvania has less info than the one from the Crimean coastline, the original version should be split off and the current one should keep the bad name and the replacement infobox that already exists in the file history. --DanTD (talk) 03:52, 14 January 2019 (UTC)

The suggested file name is invalid, a valid one would be File:Undetermined Beach in Crimea, August 2010 - panoramio.jpg (the panoramio part is usually kept).
  Info From the upload commentary you can see that the active file information is for the overwritten file. With reverse image search you can find some uses of the newer file version, all for places in Lancaster County, Pennsylvania. I found 5 different pages on tripmondo.com where the image is embedded, but more important is they provide there geo coordinates according to which the petrol/gas station is in 39°53′41″N 76°10′18″W / 39.8948°N 76.1718°W / 39.8948; -76.1718 which is apparently in Quarryville, PA, crossing of Buck Street (Openstreetmap)/West State Street (Google) with West 4th Street (in Lancaster County) – and Google Street View confirmed this.
So a suitable name for the newer image could be File:Gas station in Quarryville, PA - panoramio.jpg. — Speravir – 23:13, 16 January 2019 (UTC)
