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]

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 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:New York City Omnibus GMC Old Look TDH-5101 2969.jpgFile:NYC Omnibus GMC Old Look TDH-5101 2969 at Floyd Bennett Field.jpg, File:NYC Omnibus GMC Old Look TDH-5101 2969 at Publicis.jpg, File:NYC Omnibus GMC Old Look TDH-5101 2969 with NYCBoT Logo.jpg[edit]

  • Request: Split older versions into new names.
  • Reason: Three older versions of the file exist in three different locations, all of which can be used for this category (Category:General Motors TDH-5101 (2969)). Restoring the three older versions of the file will help expand the category, and add separate categories to older versions. ----DanTD (talk) 02:23, 3 January 2016 (UTC)
I was not sure about the exact mapping that you wanted, so I went ahead and gave the files temporary names. Please use {{rename}} template to correct the file names.
--Sreejith K (talk) 21:49, 12 January 2016 (UTC)
Thanks for the split, but the infoboxes are all wrong. The caption claiming to be for the bus at Herald Square is actually for Floyd Bennett Field. The one claiming to be outside RCB Ballpark in Staten Island, NY isn't even on Staten Island. It's actually in Manhattan. Evidently, "Number 2" is the one outside RCB Ballpark. ----DanTD (talk) 20:22, 18 January 2016 (UTC)

File:Hayabusa fuji 01.JPGFile:EF6649 Fuji Hayabusa 20090312.JPG[edit]

  • Request: Split
  • Reason: The original image was overwritten by another image taken by the same uploader on a different date.

Thanks in advance, DAJF (talk) 02:34, 3 February 2016 (UTC)

@DAJF: ✓ Done, though the destination filename was changed to File:EF6649 Fuji Hayabusa 20090312.jpg by the script. I don't know Japanese, hopefully you can sort out any errors in the file pages. Revent (talk)

@DanTD: The request you're making isn't really what this page is for, since it's not something that needs admin rights. The type of 'merging and splitting' this request page is for individual page or file histories, which requires the right to delete pages to accomplish. You should just create the two new categories, recategorize the files, and then nominate the old one category for deletion. Alternately, you can bring it up at COM:CFD if you think prior discussion is needed. Revent (talk) 14:16, 7 February 2016 (UTC)
Well, if this is something I can do myself, I'll do it. I think I'll split off the truck, and bring up the renaming of Atlantic Antic at CFD. ----DanTD (talk) 14:24, 7 February 2016 (UTC)
@DanTD: Either way (creating a new one or renaming the other, or creating two new ones and deleting the old one) works... you should actually be able to rename the category yourself (I don't think it's at all controversial), it's just that you'll either have to then recategorize the files manually or wait for the bot to do it. Whichever method seems easier to you. Revent (talk) 14:35, 7 February 2016 (UTC)
