This looks to be a regression from https://hg.mozilla.org/mozilla-central/rev/6e7d21f9e8efc7c6b657b2e28884fc3bb2b9861b. Mathieu, could you please take a look over this?

Comment 1

[:Gijs (he/him)]

This is because Cu.isInAutomation is a lie for xpcshell tests (x-ref https://twitter.com/gijskruitbosch/status/1126449767863726080 ; https://bugzilla.mozilla.org/show_bug.cgi?id=1548941#c11 ). Yes, this is a footgun, but we don't really have time to fix it here.

We can fix this by setting the relevant "allow viruses to take over this computer" pref (cf. https://searchfox.org/mozilla-central/rev/f66eb70d175a2017a74b4f61ed556d5835c8a9db/testing/profiles/common/user.js#55 ).

The question I have is... which xpcshell tests are affected? Just this one? I expect other xpcshell tests that somehow instantiate remote settings may also be affected...

Comment 2

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Dozens of tests are affected, see the xpcshell runs for a platform at https://treeherder.mozilla.org/#/jobs?repo=try&group_state=expanded&selectedJob=278883034&resultStatus=testfailed%2Cbusted%2Cexception&revision=45db0a68a4e072d658226138e201aa767cd01cba&searchStr=xpc

Shall bug 1598562 be backed out for now and later uplifted (to 72 beta) if necessary?

I think we're going to have to, yes, because which extensions tests are affected is likely a timing issue, and it'll be anything that starts up enough of the add-on architecture to trip the blocklist starting which will trip remote settings (or anything else tripping remote settings), and changing the return value of Cu.isInAutomation for all those tests is going to influence other things, so I'm not confident that we can fix it without further fallout.

:Aryx, can you do the backout?

Backed out bug 1598562 on autoland.

Verified fixed with yesterday's beta sim and on beta.
