Change Details

Let a page on a client wiki add [[[https://commons.wikimedia.org/wiki/Category:Creator_templates_with_Wikidata_link:_item_missing_linkback|a tracking category]] if the linked item is missing a P1472 statement. Then, when a P1472 is added to the item, the page should be re-renders, but it is not - it still shows the category. When purging the page, it is re-rendered, and no longer shows the category; however, the category page still lists the page. Expected behavior: after the P1472 statement is added to the wikidata item, the page on the client wiki should be re-rendered, and should no longer be listed on the category page. Hypothesis: The RefreshLinksJob scheduled by PageUpdater ends up using a cached ParserOutput, instead of re-parsing the page. Puring updates the parser cache, but doesn't update the categorylinks table.
