[Pywikipedia-bugs] [Maniphest] [Commented On] T109929: internal_api_error_BadMethodCallException: [xxx] Exception Caught: Call to a member function getNames() on a non-object (NULL)

@Joe: FYI, you should be able to grep for 'Call to a member function getNames() 
on a non-object (NULL)' in /a/mw-log/exception.log on fluorine if you need to 
look for instances of this issue. The log lines include the host, wiki 
(dbname), and query.

@jayvdb thanks, I am trying to extract the exact request that pywikibot tests 
do - just to verify better if a simple HHVM restart fixes the issue or if it 
needs a cache wipe.

@joe, `tests.api_tests.TestParamInfo.test_attributes` and other failing tests 
are always fetching paraminfo for multiple modules, similar to the request 
@Anomie mentioned.

mw1144 is the main host with a problem at the moment.

I just restarted HHVM on mw1144, and the results of a failing query are good 
again.

I think this is yet another case of stat_cache having some hiccups in HHVM. I 
will downgrade this to Normal priority for now as no host should spit any of 
such errors anymore.

This can be reproduced with the following

  $ (while true; do rm -rf tests/apicache; python -m unittest -v 
tests.api_tests.TestParamInfo.test_attributes ; done) 21 | egrep 
'^(OK|APIMWException)'

(which effectively means that it can probably also be reproduced with a single 
wget)

It can be roughly 1 in ~50 requests that fails, but sometimes it is 1 in ~20, 
and once I've seen it fail 2 times out of three requests.  Load balancing at 
work no doubt.

Anyway, it doesnt seem to matter which wiki is accessed; all failures are 
currently served by mw1144.

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=paraminfomodules=wbremovequalifiers%7Cwbremovereferences%7Cwbsearchentities%7Cwbsetaliases%7Cwbsetclaim%7Cwbsetclaimvalue%7Cwbsetdescription%7Cwbsetlabel%7Cwbsetqualifier%7Cwbsetreference%7Cwbsetsitelink%7Cwbsgetsuggestionsmaxlag=5format=json'
