Comment 25

[Edgar Chen [:edgar]]

test_bug1406102.html is a test for IntersectionObserver, so move to Layout.

Comment 26

[Chris Peterson [:cpeterson]]

Sending this bug to Layout triage. The Fission team hit this test failure multiple times when trying to enable mochitest-plain in fission-xorigin mode on more platforms in bug 1694835, so Fission and/or xorigin mode might make this infrequent intermittent failure (about 5-15 failures per week) more frequent.

https://treeherder.mozilla.org/jobs?repo=try&revision=a4813c46eff128482994870bf8a06677022cee24&selectedTaskRun=OrW1ws-wTH6pAfP9kTTeKg.0

See also bug 1694536 about intermittent IntersectionObserver test test_bug1399605.html failing more frequently in fission-xorigin mode.

Comment 27

[Daniel Holbert [:dholbert]]

As in bug 1694536, it looks like we've gone weeks without any failure reports here.

Here's a graph of failures since the start of the year -- the most recent report here was on March 25, nearly 6 weeks ago:
https://treeherder.mozilla.org/intermittent-failures/bugdetails?bug=1671539&startday=2021-01-01&endday=2021-05-04&tree=all

Maybe this is fixed? (Seems like it'd either be that, or this could be due to something like us disabling/changing the affected platform/configuration around March 25 -- cpeterson, do you know of any changes like that which could indicate that this is still an issue & we're just not getting the signal?)

The sudden disappearance of the test failure in that graph is quite interesting! I don't see any bugs that landed around that time which might have fixed this, but I will resolve this bug as "fixed" for now.

Comment 29

[Chris Peterson [:cpeterson]]

Reopening this bug because this failure was reproduced in Fission+xorigin mode for bug 1716404:

https://treeherder.mozilla.org/logviewer?job_id=342000217&repo=try&lineNumber=5795

This test_bug1406102.html test is now disabled for fission+xorigin mode on all platforms, so we won't see more failures:

Comment 30

[Neha Kochar [:neha]]

Frank, could you please assign this to someone in the Layout team? Thanks!

Comment 31

[Frank Griffith Jr]

Will be assigned on today's Layout Triage call..

Comment 32

[Daniel Holbert [:dholbert]]

(Just setting expectations: I probably won't be able to seriously look at this until mid-July, since I'll be out for most of the next few weeks. I suspect we can live with this until then, given that the test is disabled & not causing spam.)

Thanks for the heads up. In that case, I will move this bug from our current Fission Milestone (M7a) to our next (M8).

Comment 34

[Hiroyuki Ikezoe (:hiro)]

I'd highly suspect this is a case where we haven't received any transform matrix which is representing the position of the iframe in question from APZ side.

Comment 35

[Hiroyuki Ikezoe (:hiro)]

Okay, now I am also 100% sure this is not related to the test failures on fis-xorig runs (bug 1716404), since even with --enable-fission the IntersectionObserver in the test doesn't run in an OOP iframe process, it runs in the same process of the top level content document.

I've fixed the failures on fis-xorig runs in bug 1716404.

I've fixed the failures on fis-xorig runs in bug 1716404.

Hiro, what do we need to fix for this bug after you fix bug 1716404 and re-enable test_bug1406102.html for fission && xorigin?

This test is currently disabled for fission && xorigin, not all Fission. And I don't see any recent Fission failures without xorigin for this test:

I'd say we can close this bug. To be honest, I don't know the reason why this test fails on Fission runs, I only know the reason why it fails on Fission&&XOrig runs. Is it possible that we had run mochitest-fission with xorig setup in the past?

Anyway, I tried to run 1000 times this test locally with "--enable-fission" and MOZ_CHAOSMODE=255 without the change for bug bug 1716404, I didn't see any failures.

Yes. We enabled some fission && xorigin tests for just Linux debug about a year ago (bug 1647720). Last month, we enabled fission && xorigin tests on Windows, macOS, and more Linux configurations (bug 1700781). So this bug might have filed for an old test failure that was been fixed before we started filing new bugs for fission && xorigin failures found by bug 1700781.

Anyway, I tried to run 1000 times this test locally with "--enable-fission" and MOZ_CHAOSMODE=255 without the change for bug bug 1716404, I didn't see any failures.

Thanks for verifying! In that case, I'll close this bug.
