Bug ID: 65264
Summary: File storage uses (title,timestamp) as a unique key,
but this is not unique
Product: MediaWiki
Version: 1.23-git

FileRepo::findFile appears to use the (title,timestamp) pair as a unique key to
identify a particular version of a file. However, this is not necessarily
unique. See for example
https://commons.wikimedia.org/wiki/File:Treppe_22_22_test_upload.jpg where two
versions were both uploaded at 2014-05-05T13:00:59Z.
For proper operation, the API requires some ordered unique identifier for file
revisions. I imagine there are other places in the code that also require
unique identifiers.
This appears to depend on bug 15441 (for the oldimage table), although I'm not
familiar enough with the FileBackend code to know for sure whether that's
generally the case or if it only applies to certain backends.
