There's likely to be a lot of different leaks buckets under this failure, but I'll move this to DOM: Core.

I filed some bugs for instances of this leak that have shown up a few times. As with the older bug, I think the most common cause is the directory devtools/client/webconsole/test/browser/_browser_console.toml . That's a parent process leak, so I can't tell from the logs alone what test might be responsible.

I think Jens's patch in bug 1861252 could fix the remaining leaks we have for about:neterror being held alive by pending Servo tasks.

Andrew, do you have time to take one more look at this?
The patch in Comment 11 does not seem to have had any effect on this failure.
Thank you.

I'll try and take a look when I'm back from vacation next week, but it does look like there was a large increase in the failure rate in the last day or two.

Looking at the most recent failures, there seem to be a bunch while running devtools tests. Based on a sample of 4 of these logs, the leak is happening while running the tests in devtools/shared/network-observer/test/browser/browser.toml . browser_networkobserver_auth_listener.js and head.js from that directory were changed in bug 1353798 which landed on 2023-12-19. That sort of lines up with the spike I saw, but not quite, and also per comment 24 it was fairly high even before that, so maybe that's a red herring. I'll see if I can reproduce the leak locally.

Flags: needinfo?(continuation)

I reproduced a leak first try when running the directory locally, although it was for a content process leak and not a parent process, like the logs I looked at, so I don't know if it is the same issue. The content process was created while running browser_networkobserver_auth_listener.js which sort of lines up with my previous comment.

Depends on: 1872916

I spun off my discussion of this leak to bug 1872916, to avoid cluttering up this bug too much, and because I'm not sure it is the same leak we are seeing in automation.

Depends on: 1873571

I put a patch up for review in bug 1873571 that seems to reduce the devtools leak rate from 2/15 to 0/15, at least judging by a try run.

No longer depends on: 1872916

Andrew, do you have a few minutes to take another look at this?
Thank you.

I've started looking into this.

First, I looked at the Mochitest-plain failures. For the xorigin ones, we can see which test created the process where the leak is, which may or may not indicate something. There were 5 failures for processes created during the dom/base/test/test_bug1648887.html test. However, I could not reproduce a leak when running that test locally in isolation. There were also two failures (1 each) for for tests in toolkit/components/extensions/test/mochitest/ (test_ext_webrequest_errors.html and test_ext_webrequest_background_events.html). There were also a few failures in tests for dom/security/test/csp/. Looking at the non-xorigin plain failures, there were a lot of failures while running the toolkit/components/extensions/test/mochitest/ directory. So, not a lot to go on here.

I've started looking at the Mochitest browser-chrome tests. I haven't found any pattern there yet, but I did notice that we are getting leakcheck failures for DOM leaked windows created during tests. These should show up as failures that look like "leaked 3 window(s) until shutdown". However, I don't see any intermittent failures like that that have activity after the middle of last year so that appears to have broken. I'll have to file a separate bug for that. Also that doesn't really help this.

Anyways, the bottom line here is that no individual failures is super common. Mostly this is a consequence of every window leak getting bucketed together.

I looked through some recent failures here in mochitest browser chrome. Because those have the ++DOMWINDOW information, we can find out which test created the window that is leaking using a script I wrote.

These are all over the place. 3 of them happened twice, so maybe it would be worth investigating those some more, but unless there's some non-obvious commonalities between these tests, it doesn't look like there are any easy wins here to get the failure rate down. For these bc's maybe the test harness could be made smarter and these failures could get turned into failures for the individual tests. Maybe that's worth exploring, although it would not help the orange factor.

I went back and broke down the failures from the last week in mochitest plan (non-xorig) and devtools a bit more.

Mochitest plain, non-xorig:

  • 7 tab toolkit/components/extensions/test/mochitest/mochitest-remote.toml:toolkit/components/extensions/test/mochitest/mochitest-common.toml
  • 2 tab dom/base/test/mochitest.toml
  • 1 tab toolkit/components/extensions/test/mochitest/mochitest.toml:toolkit/components/extensions/test/mochitest/mochitest-common.toml
  • 1 tab dom/tests/mochitest/general/mochitest.toml

mochitest devtools

  • 13 default devtools/client/webconsole/test/browser/_browser_console.toml
  • 3 tab devtools/client/accessibility/test/browser/browser.toml (leaking windows created while running devtools/client/accessibility/test/browser/browser_accessibility_print_to_json.js )

That's out of 48 total failures. So there actually is some hope of fixing one or two issues and bringing the rate down. I'll see if I can reproduce them.

I did a bunch of retriggers with logging enabled for the devtools directory that is leaking, without success. Maybe I need to run it not in isolation.

Andrew, is this still on your radar?

Huh, something seems to have gotten a lot worse on MacOS. A large chunk of the failures in the last week are MacOS while running mochitest-browser-chrome-3. Looking at some of the logs, it seems like one of the windows that is leaking was created during the dom/base/test/browser_multiple_popups.js test. You could try disabling that on MacOS debug. (It is already disabled on MacOS opt...) I can try to investigate the failure but I haven't been able to reproduce it yet.

One thing I noticed is there seem to be roughly weekly spikes in failures. It also looks like it could be over the weekend? Is there some test that is affected if it runs on Saturday? Very weird.

if you are looking at the graph of failure rate, then weekend spikes are normal as we have fewer pushes which means our 10+ full pushes we do daily on autoland/m-c which run all tests in all permutations have a more dominant role in failures/push. The real metric we would like to have is failures/run- that is somewhat solvable for a given test filename, but for leaks on a whole array of task names, it becomes slightly more complicated.

For window leaks in mochitest BC, we could probably assign blame to a specific test, FWIW, using the ++DOMWINDOW annotations we're already using for another leak test.

Henri, as the owner of this component, can you help us assign the bug to someone? Thank you.

I'll try to take a look here. The basic issue is that failures from many different tests are bucketed together so this one really stands out. It would be good to split them up more so we could catch regressions more easily, but it would not otherwise help the overall orange volume.
