Bug #: 31792
Summary: Mediawiki losing old file versions upon undeletion in
MW 1.18
Product: MediaWiki
Version: 1.18
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: Unprioritized
Component: Images and files
AssignedTo: wikibugs-l@lists.wikimedia.org
ReportedBy: magog.the.o...@gmail.com
CC: bawolff...@gmail.com, bryan.tongm...@gmail.com
Classification: Unclassified
Since the most recent MW version upgrade, I've now had Mediawiki lose two
different old versions of a file while in the process of deletion. Let me
explain:
* User uploads version A to Myfile.jpg.
* The same user or a different user uploads version B to Myfile.jpg,
overwriting the old version.
* I delete Myfile.jpg.
* I go to undelete version A, but when I undelete the file, version B pops up.
Looking in the file history, version B is now version A, even though the
resolution information (and IIRC the sha1 information) are still different.
Thus version A is forever gone.
You can see this occur at two files:
* http://en.wikipedia.org/wiki/Special:Undelete/File:University.JPG: in this
case, only one deleted version appears in the history because I was trying to
perform a history split. See
http://en.wikipedia.org/w/index.php?title=Special:Log&page=File%3AUniversity.JPG.
However, you'll notice the deleted revision is inexplicably identitical to
http://en.wikipedia.org/wiki/File:Sindh_Agriculture_University.JPG.
*
http://en.wikipedia.org/wiki/Special:Undelete/File:Kolkata_Tipu_Sultan%27s_Mosque3.jpg:
you'll notice that the software lists two different files at two different
resolutions. However, if you actually click both of the old versions, you'll
get the same file (445x387: the newer one uploaded).
Do I need to file a bug for this? Or is there already a bug filed?
