Filtering for RevisionDeleted edits
|
|
Hi,
since some time we have RevisionDelete, which allows deleting specific
revisions of a page without having to delete the whole page. This
feature is currently enabled for Oversight on WMF wikis and the
community wants it to be enabled for regular administrators[1].
The only bug currently blocking this request is
https://bugzilla.wikimedia.org/show_bug.cgi?id=20186
which requests an easy method to filter history and contributions lists
for RevisionDeleted edits.
I partially fixed that bug in r58153, but afaik there is a problem with
the current database layout:
To filter for revisiondeleted edits, one has to go through all
history/contributions lists and look at each individual revision if it
is rev_deleted or not. This clearly isn't efficient and fails for pages
that have a large history.
Afaik, a database change is needed to make filtering for RevisionDeleted
edits efficient for large pages (I'm no DB expert, though).
Any suggestions on this problem?
Regards,
Church of emacs
