A Pernosco session is available here: https://pernos.co/debug/PxyLIUGmsLpFr5-GyG31Zg/index.html

This is easily reproduced by visiting the test case:

Part of bug 1684781 perhaps?

Severity: -- → S3
Flags: needinfo?(gwatson)
Priority: -- → P3

Doesn't seem to repro on my local setup, and the pernosco session is unfortunately not helpful here as the code in question is all inlined and so the callstack doesn't identify the caller.

Flags: needinfo?(gwatson)

Glenn, I am able to repro on my local setup (Ubuntu 20.04) with Grizzly replay using a debug build (m-c 20210325-2da6d806f457).

To install Grizzly:

python3 -m pip install grizzly-framework

To repro with the attached test case and prefs.js files:

python3 -m grizzly.replay <build_path>/firefox testcase.html --repeat 10 --relaunch 1 --xvfb -p prefs.js

Note: --xvfb isn't required for me but it does make the execution a bit more consistent.

Does that help?

Flags: needinfo?(gwatson)

This is the output I get when I run that command:

I ran it many times both with and without the --xvfb option. It's definitely a full debug build, I'm not sure if the log related to symbols not being found might be relevant. Are there are only options I could try to repro locally?

Flags: needinfo?(gwatson) → needinfo?(twsmith)

Hmm that's interesting, let me side track a little bit here...

The symbols_path not found msg means a minidump was found but the Result: Ignored and time diff indicate a timeout occurred.

So we should see one or the other, not both. This pointed out a bug in our tools and I fixed it this morning. OTOH it should still not have hung, so I'm not sure what's up with that but hopefully this fixes it.

Would you mind trying again with the latest FFuppet (0.7.7)? pip install ffpuppet --upgrade should do what you need. Adding --log-level DEBUG to the grizzly.replay command would also be helpful in case there are more bugs in our tools.

Now back to the bug we are trying to catch.

I tested again this morning with the latest fuzzing debug build and triggered it first try. I was also able to reproduce on an 18.04 machine. I even triggered it with a m-c opt build.

If you have a patch I'd be happy to run it or I can get an updated Pernosco session. I am building with -O0 to avoid in-lining, any ideas why that would be happening?

Flags: needinfo?(twsmith) → needinfo?(gwatson)

Output from doing the update and adding debug logging, still doesn't seem to repro for me, which is very odd. I tried with an opt / debug / debug no-inlining build. Is there anything else obvious I might be missing? Could it be related to screen resolution or device-pixel scaling ratio perhaps?

(In reply to Glenn Watson [:gw] from comment #10)

Thank you for the logs! It looks like it is working as expected now.

Output from doing the update and adding debug logging, still doesn't seem to repro for me, which is very odd. Is there anything else obvious I might be missing?

I really have no idea what it could be. When I was trying on other systems I was hoping I'd catch the problem. Side note, it looks like this was last reported by fuzzers with m-c 20210322-7bff3dc37b07. I don't know if it was easier to trigger before that or what.

Could it be related to screen resolution or device-pixel scaling ratio perhaps?

Usually Xvfb is how we deal with that but it doesn't look like it mattered in this case. I tested on my laptop (Ubuntu 20.04, X1 Carbon) but could not reproduce it there.

This is the about:support from the VM that I can consistently reproduce the issue on.

After only one crash earlier this week, this signature gets crash reports submitted again starting with 89.0a1 20210331092207 (crashes from 19 installs). Could this be related to the rust upgrade in bug 1700562? Because the webrender changelog doesn't contain any suspicious for that build.

(In reply to Sebastian Hengst [:aryx] (needinfo on intermittent or backout) from comment #12)

After only one crash earlier this week, this signature gets crash reports submitted again starting with 89.0a1 20210331092207 (crashes from 19 installs). Could this be related to the rust upgrade in bug 1700562? Because the webrender changelog doesn't contain any suspicious for that build.

I have been experiencing stable crashes on webrender::picture::PicturePrimitive::take_context since some nightly on March 31. It can be reproduced stably on my profile with a certain userscript [1] on ViolentMonkey on a certain website [2], but not fresh profiles.

Mozregression indicates the bisect pushlog as follows: https://hg.mozilla.org/integration/autoland/rev/be0f7947d378a4764a10bd3e676e859146efa445

Feel free to NI if there's anything I can help with.

  1. https://github.com/the1812/Bilibili-Evolved/blob/4dc90004ffe49cf5b41727d1b5a56fd2edbc74f1/bilibili-evolved.user.js
  2. I used https://www.bilibili.com/video/av203387849 for tests, but typically any video link on this website is affected.

Needinfo'ing gw based on possible regressor from the last two comments.

Flags: needinfo?(gwatson)

[Tracking Requested - why for this release]: Apparent crash regression that is showing up on Nightly stability and has a test case. I'm also marking 88 for tracking because the apparent regressor bug 1700539 was backported to 88.

Keywords: regression
Regressed by: 1700539

Hmm I guess the initial bug was filed a bit earlier, so maybe we need a new bug for the crash on Nightly?

For the crash I experienced, here is a STR:

  1. Open a new profile on Nightly older than Mar 31
  2. Install Violentmonkey
  3. Import the attachment in "Settings" > "Data Import" > "Import from zip" to install the forementioned userscript (and its cache on my profile, which is essential to trigger the crash)
  4. Open an affected page (e.g. https://www.bilibili.com/video/av203387849)

It's far from MRE but hopefully it helps.

See Also: → 1702662

tracking+ for now, but it sounds like this might overlap with bug 1702662

Changing the priority to p1 as the bug is tracked by a release manager for the current beta.
See What Do You Triage for more information

Priority: P3 → P1

I'm going to see if I can reproduce and investigate this today with the steps in c18, thanks!

Thanks for the additional repro in comment 13. I can confirm I was able to repro that locally, and there is a patch in bug #1702662 which fixes this for me. Please see https://bugzilla.mozilla.org/show_bug.cgi?id=1702662#c12 for more context.

Blocks: domino

The patch from bug 1702662 definitely resolved the crash spike attributed to this bug, but I'm a bit worried that the original fuzz bug was filed prior to the regressing bug 1700539 landing. Is there still a testcase which reproduces this, Tyson? Regardless, we can drop the tracking status here as its immediate impact appears to have been mitigated.

Flags: needinfo?(twsmith)

The original test case still reproduces the originally logged issue as of m-c 20210406-b85e871f6a8d.

A updated Pernosco session can be found here: https://pernos.co/debug/J0BqJvtp3LFuB_LZJ1MheQ/index.html

I see some of the rust code is being removed. I will investigate further in bug 1703330.

An updated Pernosco session is available here: https://pernos.co/debug/aOylcvIaD2zhRiOsQBdaRA/index.html

The rust optimization issues should be fixed.
