Comment 15

[Alexandru Michis [:malexandru]]

Andrew, the recent failure rate spike looks to be caused by Bug 1694824.

Looking at the Intermittent-Failures view shows the increase started once the tests were enabled on Autoland.
Could you please take a look? Should these be disabled?

64 failures in 3065 pushes (0.021 failures/push) were associated with this bug in the last 7 days.

Yes, this looks to fail much more frequently on fission. Can we treat these the same as we do any other intermittents at this point? I enabled these tasks on behalf of the fission team but don't have any special insight there. I also don't think they should be treated differently than any other platform, though :cpeterson would likely appreciate a needinfo if you end up skipping them.

Comment 18

[Andrew McCreight [:mccr8]]

Yeah, I'd just re-disable this for Fission if the failure frequency is too high. I'll nominate it for Fission tracking so it can be triaged with the other failures.

Comment 19

[Chris Peterson [:cpeterson]]

We may be shutting down the privileged about: process and respawning a new one, causing the test to fail.

kmag says we should add some process type assertions to ensure we're not mixing up the privileged about: process with some unprivileged process.

Attachment: Bug 1643998: Check actual remote type along with PID when testing for privileged about: process. r=nika

We're getting some intermittent failures on automation where the PID does not
match the original privileged process in some checks. It isn't clear whether
that's because we're actually not in a privileged process, though, or whether
the original privileged process was simply replaced.

The new checks will tell us both things.

Hi Kris, should this be re-enabled on fission Linux and OS X?

Comment 28

[Kris Maglione [:kmag]]

Based on the new failures, it looks like we are in fact doing the Bad thing:

TEST-UNEXPECTED-FAIL | browser/base/content/test/tabs/browser_new_tab_in_privilegedabout_process_pref.js | Check that about:newtab after location change is loaded in privileged about: content process. - Got "webIsolated=http://example.org", expected "privilegedabout"
