Title:moveTo() explicitly sets createRedirect to false (redirid == 0) SMWSQLStore3Writers::changeTitle() never checks the redirid therefore smw_fpt_redi contains gost redirects for pages with (Special:MovePage - > Leave a redirect behind unchecked)
There are two approaches to change this behaviour:
- Execute updateRedirects() only when $redirid != 0 which will means that all possible existing associations with a moved page are also gone or
- Execute updateRedirects() in all cases (copying associations with the moved page) but in case of $redirid == 0 execute doDataUpdate( $oldtitle ) in order for the oldTitle (which got deleted) to delete the container for the oldTitle object as well.
Note
The hook ArticleDelete is not called for a moved oldTitle therefore deleteSubject() is also not called which means the container for oldTitle still has a references to the newTitle (see smw_fpt_redi).
Example
See [1], [2] where [1] is delete but shows semantic data from [2]. When looking at "Has query" property reveals that Demo:Foo has suddenly elements of Demo:Foo2.
