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[edit]

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.

History splitting[edit]


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 filename. 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.

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.

Current requests[edit]

File:BSicon exACC.svgFile:BSicon xACC.svg[edit]

  • Request: Move the older two versions (with dark blue disk) to File:BSicon xACC.svg
  • Reason: Different BSicons

✓ Done But there were three dark blue versions. @YLSS: please verify. Ankry (talk) 14:05, 17 January 2015 (UTC)
Maybe one on them was hidden in deleted revisions... Thanks. YLSS (talk) 20:48, 17 January 2015 (UTC)

File:BSicon uexSKRZ-Au.svgFile:BSicon uxAROADu.svg[edit]

  • Request: Move the older version (with maroon stripes across) to File:BSicon uxAROADu.svg (as the original version)
  • Reason: Different BSicons

-- YLSS (talk) 16:08, 28 December 2014 (UTC)

I doubt there is any point to do this: moving older version 0f the image requires to move also its desctiption page history. The older version of File:BSicon uexSKRZ-Au.svg has description history till 16 Apr 2013. And the File:BSicon uxAROADu.svg contains different image with descriptions since 31 May 2008. So after such move we would have history mess in the range 31 May 2008 - 16 Apr 2013. I refuse to move unless threre is some real advantage of doing this. Ankry (talk) 14:05, 17 January 2015 (UTC)
Well, there's no immediate advantage, as no new image will appear. Actually, it seems that there was once quite a lot of trouble with such icons, cf.   (SKRZ-Au) vs.   (eAKRZu) vs.   (SKRZ-Bu). I though it would be OK to make the things clear, which of them appeared from which etc., leaving in place only the original and the ultimate versions, and just to delete anything in between. But if you say it isn't worth the trouble, OK. YLSS (talk) 21:20, 17 January 2015 (UTC)

This ✓ Done. First version has been split. But for last version I do not see reason on COM:FR for renaming.--Anatoliy (talk) 13:47, 10 January 2015 (UTC)

✓ Done. Last version I left with current name.--Anatoliy (talk) 13:56, 10 January 2015 (UTC)
Thanks, Ahonc. I renamed the files myself. I know that there isn't anything like that at COM:FR, but I suppose restoring the original filename that was both given to it by the author and in all probability intended by the uploader — but was trimmed due to a software bug — is still OK. Possibly this can be viewed as a combination of criterion #2 (more precise information, especially seeing that there are several files with such names) and #6 (because the file names were generated automatically from the flickr titles and may be needed for backward compatibility etc.) YLSS (talk) 14:43, 10 January 2015 (UTC)
