Component: Agent → Networking: WebSockets
Product: Remote Protocol → Core

That's actually a crash we haven't seen so far for the remote protocol tests. I wonder if it is somewhat related to my changes from yesterday:
https://hg.mozilla.org/mozilla-central/rev/adc5e45e75aa#l1.56

Basically we switched from a number to a string for an object property that we return via the socket to a connected client.

I can get this crash happening all the time with my patch series on:
https://phabricator.services.mozilla.com/D96009

https://treeherder.mozilla.org/jobs?repo=autoland&group_state=expanded&revision=a1900289bdac31b543a5d4e46cbd7aae22599a0e&searchStr=tv%2Cmac%2Cwebrender%2Cdebug

But I don't know how to trigger the verify jobs for browser chrome tests on MacOS webrender debug on try. It's not appearing in the list of available test jobs when running mach try fuzzy --full. And tests for normal debug builds are passing fine. Maybe it's a fallout from the changes from bug 1673071? Kats can you have a look? I think for now I will disable the test for this particular platform.

Flags: needinfo?(kats)

If the failure is somehow specific to the WebRender codepath then it might be fallout from bug 1673071. However it looks like this has been happening for a while on non-qr platforms too so I don't think the underlying problem is specific to qr.

The relevant verify job is listed as test-macosx1014-64-qr/debug-test-verify-e10s in the ./mach try fuzzy --full listing. The verify job inherently only runs tests that have been modified in the push, so if you apply your patches from bug 1675266 and push that job you should be able to trigger it. I kicked off a try push here: https://treeherder.mozilla.org/#/jobs?repo=try&revision=aad5804b409b54a9a04e45bef5067c579155165b

Let me know if you need additional help from me. It looks like this is a crash in networking code so it's in code I'm not familiar with and it doesn't seem specific to WebRender. Since you have a reliable reproduction you might want to ask somebody on the networking team to take a look.

Flags: needinfo?(kats)

Oh my bad. I missed to rebase my bookmark against latest mozilla-central. That's why I wasn't able to find these jobs. Given that your job passed just fine I triggered a new full one for Pernosco:

https://treeherder.mozilla.org/jobs?repo=try&revision=74e297f547dc82e75e82d60bfbb52abaa608224c

Lets wait until bug 1675266 has been fixed. Then it will be easier to retrigger this failure. I will report back with more detailed steps later today.

To replicate the crash permanently follow these steps:

  1. Apply the changes from https://hg.mozilla.org/try/rev/2b85e43115bcf89157800897005affdb0c78bdfb
  2. Make sure that you are generating a debug build
  3. Run mach mochitest --enable-webrender --setpref=media.peerconnection.mtransport_process=false --setpref=network.process.enabled=false --setpref=layers.d3d11.enable-blacklist=false --flavor=browser --subsuite=remote --verify remote/test/browser/browser_httpd.js --headless

Here a try build that demonstrates that it's nearly perma-failing:
https://treeherder.mozilla.org/jobs?repo=try&revision=eb48f97514dc4e9be8ec56e749e6d4ebd96ec137

Jens, could someone please have a look at this as long it fails that often? Thanks.

Dragana, do you have an update for us? Thanks.

I am not sure why this is failing.
he crash is happening when WebSocketChannel is release which releases WebSocketsImpl on the TimerThread.
The strange think here is the WebSocketChannel should proxy release of WebSocketsImpl to the main thread, but it doesn't.
Here is that line:
https://searchfox.org/mozilla-central/rev/03224522336f60a1a61a87e1fcd4feb0a0315a9b/netwerk/protocol/websocket/BaseWebSocketChannel.cpp#358

I could not reproduce the problem locally to try to debug it. I also used steps from comment #15.

Flags: needinfo?(dd.mozilla)

Henrik, can you reproduce it locally?

Flags: needinfo?(hskupin)

(In reply to Dragana Damjanovic [:dragana] from comment #32)

Henrik, can you reproduce it locally?

No, I've never seen the assertion and crash locally. And I only have MacOS, and cannot test on Linux where it happens way more often. Sorry.

Flags: needinfo?(hskupin)

Given that the problem is happening mostly on Linux in CI maybe you could try to catch it in Pernosco?

Flags: needinfo?(dd.mozilla)

I actually triggered a try build with --pernosco and got a crash reproduced:

Currently figuring out how to get the link to the Pernosco recording.

Dragana are there any updates here?

Flags: needinfo?(dd.mozilla)
Whiteboard: [stockwell unknown] → [stockwell needswork:owner]

This will be fixed by bug 1660307.

I am interested if we can find the underlying cause of this problem.
The distruction should be dispatched on the correct thread, but thread is shutting down and does not accept dispatches.

I will leave this bug open for now.

Flags: needinfo?(dd.mozilla)

That sounds great! Does it mean I do not have to figure out how to get a Pernosco session for it?

I assume, it is still worth the effort. The fix will just heal the immediate crash but the unexpected root cause needs still to be understood and a pernosco session would be very helpful for that.

There is nothing that I can do right now. As it looks like the --pernosco option is broken. I filed bug 1694586 for that.

Kyle tried a lot to get it reproduced on the Pernosco infrastructure but without avail (see bug 1694586 comment 11). Maybe I can find something when I start working on the failure for bug 1609162, which might be in some relation to this crash. I'll let you know.

Dragana, do we have an update here? Sadly I cannot access this bug.

Kershaw is looking into this in bug 1660307

Flags: needinfo?(dd.mozilla)

Bug 1660307 just got fixed. But the intermittent failure view shows that the crash already stopped happening on April 5th:
https://treeherder.mozilla.org/intermittent-failures/bugdetails?startday=2021-04-01&endday=2021-04-06&tree=trunk&bug=1663533

Given that it was not a perma failure it's not clear when in this list it got fixed:
https://treeherder.mozilla.org/jobs?repo=mozilla-central&searchStr=linux%2Cwebrender%2Cremote&fromchange=1ec31daa1ae0f63d25e3364538f0cd9b78a84f3d

I triggered some additional jobs. Maybe we can nail it down if no-one else might have an idea what could have fixed it.

As it looks like we got a fix for that crash with the merge to mozlla-central by April 7th:

https://treeherder.mozilla.org/jobs?repo=mozilla-central&searchStr=linux%2Cwebrender%2Cremote&fromchange=b85e871f6a8d57cdc744634dadb2b0af88422504&tochange=e06c2941cdfc56de10e6b4fdd0ddfaff800e6b56

I can see that bug 1695580 was part of it, and by the description it should indeed have fixed this crash. I assume we can mark this bug fixed?

Flags: needinfo?(dd.mozilla)
Flags: needinfo?(apehrson)

This should have been fixed by https://phabricator.services.mozilla.com/D109783. A crash like this started spiking with only the other patches on the bug.
