Summary: rollback of page blanking does not restore pagelinks
Product: MediaWiki
Version: 1.14-svn
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: Normal
Component: Database

If a vandal blanks a page and that edit is rolled back, the page is restored to
Wikipedia but pagelinks is not restored. As far as pagelinks is concerned,
that page has no outgoing links. The problem goes away with a null edit.
I've seen this happen with page blanking and when vandals replace content with
"hi" etc. Also, I've seen it when ClueBot does the rollback, and when a Huggle
user does the rollback, so it isn't a bot-only problem or something like that.
This could happen with every rollback. It has come to my attention because
I've created a toolserver page that builds a list of deadend pages, and I kept
getting articles that had no business whatsoever in the list - Yoko Ono, for
instance.
How to reproduce:
1) Pick one of these articles I've found to exhibit the bug (as of time of
writing): "2006 Winter Olympics", "Infectious disease", "List of poems"
2) Verify that the last edit in its history is a user rolling back blanking
vandalism
3) Pick any link on the page (on "Infectious disease", I chose "Clostridium
difficile") and click it
4) Click "What links here" for the random link
5) Search the "What links here" list for your article, it isn't there
This is causing a problem for me because if it weren't for this bug, my deadend
articles list would be suitable for a bot to use for auto-tagging. But because
of this, everything must be reviewed manually.
