The pywikibot-core tests testing the categories of Albert Einstein on the English Wikipedia are failing recently:
- https://travis-ci.org/wikimedia/pywikibot-core/jobs/56190901#L2710
- https://travis-ci.org/wikimedia/pywikibot-core/jobs/56190905#L2071

Now when looking at the call [[https://en.wikipedia.org/w/api.php?action=query&prop=categories&titles=Albert%20Einstein&clprop=hidden|action=query&prop=categories&titles=Albert Einstein&clprop=hidden]] it returns just 6 hidden categories. Just for clarification it's clprop not clshow and a similar call to [[https://en.wikipedia.org/w/api.php?action=query&prop=categories&titles=The%20Big%20Bang%20Theory&clprop=hidden|action=query&prop=categories&titles=The Big Bang Theory&clprop=hidden]] returns also normal (not hidden) categories.
{ "warnings": { "query": { "*": "Formatting of continuation data will be changing soon. To continue using the current formatting, use the 'rawcontinue' parameter. To begin using the new format, pass an empty string for 'continue' in the initial query." } }, "query": { "pages": { "736": { "pageid": 736, "ns": 0, "title": "Albert Einstein", "categories": [ { "ns": 14, "title": "Category:All articles lacking reliable references", "hidden": "" }, { "ns": 14, "title": "Category:Articles lacking reliable references from March 2015", "hidden": "" }, { "ns": 14, "title": "Category:CS1 maint: Unrecognized language", "hidden": "" }, { "ns": 14, "title": "Category:Good articles", "hidden": "" }, { "ns": 14, "title": "Category:Wikipedia indefinitely move-protected pages", "hidden": "" }, { "ns": 14, "title": "Category:Wikipedia indefinitely semi-protected pages", "hidden": "" } ] } } } }
I tried purging it and only a few hours ago ClueBot NG reverted a vandalism edit. That vandalism also removed all normal categories so it might be connected.
