In bug 1035222 we had to run init_datasources on treeherder-dev. update.py doesn't do this currently, and I'm guessing it needs to otherwise bug 1035222 and similar won't get deployed on production. https://github.com/mozilla/treeherder-service/blob/master/deployment/update/update.py#L44
Created attachment 8493645 [details] [diff] [review] Call manage.py init_datasources during Chief deployment
Commit pushed to master at https://github.com/mozilla/treeherder-service https://github.com/mozilla/treeherder-service/commit/41384c5b6b1ceed635661aaab24740a4dbd38fe7 Bug 1069283 - Call manage.py init_datasources during Chief deployment
This is now being called during update.py (eg http://treeherderadm.private.scl3.mozilla.com/chief/treeherder.prod/logs/master.1411475198), though the new repos aren't appearing yet, so have filed bug 1071570 to investigate further.
