Anomie added a subscriber: Anomie. Anomie added a comment. I could reproduce this by directing copies of the erroring queries to mw1230, mw1147, and mw1200; it didn't happen with the same queries directed to different hosts. Nothing in the code looks suspect.
I tried using some live hacks on those hosts to see what was going on. The $module->getFinalParams() call from ApiParamInfo was returning the params for ApiMain instead of for the module in question for some unknown reason. But as soon as I touched ApiBase.php the bug was suddenly fixed, which makes me suspect some sort of HHVM code-cache corruption. I haven't touched mw1200 in case someone who knows more about HHVM wants to look into it. To test it from terbium, use this command: curl -H "Host: www.wikidata.org" 'http://mw1200.eqiad.wmnet/w/api.php?action=paraminfo&modules=wbremovequalifiers%7Cwbremovereferences%7Cwbsearchentities%7Cwbsetaliases%7Cwbsetclaim%7Cwbsetclaimvalue%7Cwbsetdescription%7Cwbsetlabel%7Cwbsetqualifier%7Cwbsetreference%7Cwbsetsitelink%7Cwbsgetsuggestions&maxlag=5&format=json' TASK DETAIL https://phabricator.wikimedia.org/T109929 EMAIL PREFERENCES https://phabricator.wikimedia.org/settings/panel/emailpreferences/ To: Anomie Cc: Anomie, Krenair, Aklapper, pywikibot-bugs-list, jayvdb, Joe, jeremyb, Legoktm, greg, Malyacko _______________________________________________ pywikibot-bugs mailing list pywikibot-bugs@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/pywikibot-bugs
