Comment 13

[Alexandru Michis [:malexandru]]

Daniel, this is happening on mochitest plain jobs as well: https://treeherder.mozilla.org/logviewer?job_id=338081176&repo=mozilla-central&lineNumber=2017

Should we open a new bug for these or modify this bug's summary to include them?

Comment 14

[Daniel Holbert [:dholbert]]

I assume "this is happening" you're referring to the "should have done initial reflow" assertion -- is that right? If so: yes, let's use a new bug for the other test where this has been seen. Thanks!

Also: I think this bug actually may have the wrong assertion-text in its description. In the log from comment 0 here and also the log linked in comment 3 (and I assume the others - those are just the instances that I've looked at), it looks to me like the actual assertion-failure during this test is quite different:

Both logs do also have one instance of ASSERTION: should have done initial reflow by now: 'mDidInitialize' somewhere in the log, but it's during a different test (436900-2.html) and it seems to be an expected-fail there. (That test is annotated as having 0 to 1 assertions, with this being the occasional-assertion, I assume).

So I don't think this bug is really about that "should have done initial reflow" assertion at all.

--> Adjusting bug summary to reflect the correct assertion text, per comment 14. (Please correct me if I'm missing something, though.)

Also: I'm not sure if this is related, but it's interesting -- in both of the failure logs that I linked in comment 14, the logging includes an interesting note that suggests this test was the slowest test and took over a minute (104 seconds in one case, 74 seconds in the other):

The log from comment 0 has:

REFTEST INFO | Slowest test took 104371ms (file:///builds/worker/workspace/build/tests/reftest/tests/layout/generic/crashtests/471360.html)

The log from comment 3 has:

REFTEST INFO | Slowest test took 74131ms (file:///builds/worker/workspace/build/tests/reftest/tests/layout/generic/crashtests/471360.html)

It looks like the test does some sort of repeated self-editing (boom1 calls boom2, which calls boom3, which callsboom1`, all via seetTimeouts)

We probably should place an upper-bound on the amount of cycling here, or else the test can keep running for an indefinite amount of time, due to the fact that the test harness waits for paints to stabilize.

Also fwiw, it looks like we have several other intermittent-failure bugs with the same Unexpected layers id in AllocPAPZParent assertion failure: bug 1676017 and bug 1655640, at least.

[Alexandru Michis [:malexandru]]

Thank you for taking a look!
Made Bug 1708332 for the failure I mentioned in Comment 13.

Comment 19

[Daniel Holbert [:dholbert]]

Note, this particular test also seems to be causing a "load failed: timed out waiting for pending paint count to reach zero" failure on aarch64 (per bug 1700634), which makes sense for reasons discussed in comment 15 here. Sample log:
https://treeherder.mozilla.org/logviewer?job_id=338238518&repo=mozilla-central&lineNumber=25300

The attached patch (putting an upper-bound on the cycling) should address that, as well as the "slowest test" issue noted here. I'm not sure if it'll fix the assertion-failure as well (the thing that this bug is really focusing on), but it seems like it might. (And we can reopen this after the patch lands if it doesn't.)
