Bug ID: 71171
Summary: namespaceDupes.php doesn't update references in other
tables for pages it moved
Product: MediaWiki
Version: unspecified

OS: All
Status: NEW
Severity: normal
Priority: Unprioritized

namespaceDupes.php is used when introducing a new namespace, to check/move
titles that already use the new (namespace) prefix to be introduced.
The actual rename happens in NamespaceConflictChecker::resolveConflictOn() in
namespaceDupes.php. All it does is update the pages in the `page` table.
However, there are plenty of other places that reference such namespace/title
pairs that are not properly updated.
Is there any reason NamespaceConflictChecker::resolveConflictOn() doesn't use
Title::moveTo? That one does seem to update references in a lot of the other
tables as well, and runs hooks (TitleMove & TitleMoveComplete) that extensions
can subscribe to in order to update their data.
Can we change it to use Title::moveTo?

contain incorrect references after such rename:

references in `watchlist` table:
