There are 189 total failures for the last 30 days on linux1804-64-asan platform.

Andrew, can you please take a look?

This is a really generic signature, that basically indicates we leaked a bunch of stuff. It looks like it really spiked up in the last day.

Maybe somebody could narrow down when it started happening frequently a bit more? Specifically the linux1804-64-asan mochitest-browser-chrome-e10s-10 and mochitest-browser-chrome-e10s-11 failures.

Looking at about a dozen recent failures, they are happening in the directory: browser/components/downloads/test/browser/

I would expect that there's a similar very frequent leakcheck failure in that directory as well.

I don't see any recent test changes in that directory. Gijs, any guesses about what code changes in the last 24 hours might have caused a lot of failures here?

Contrary to what the graph looks like, the first failure I can see in this downloads test directory is from the 9th: https://treeherder.mozilla.org/logviewer.html#/jobs?job_id=305648028&repo=autoland&lineNumber=2627 directory

I don't see any high frequency leakcheck failures on Orange Factor. I'm not sure what that means.

I've started some retriggers in the dozen or so pushes before the failure in comment 14.

Started a few retriggers on this range:
https://treeherder.mozilla.org/#/jobs?repo=autoland&searchStr=Linux%2C18.04%2Cx64%2Casan%2Copt%2CMochitests%2Ctest-linux1804-64-asan%2Fopt-mochitest-plain-e10s-4%2CM%284%29&tochange=f4613d8061962ee45e2b06a05dad4c0a2dd26623&fromchange=4000e4a6dc964935bc301446f6049e79e5cb4597&selectedTaskRun=GKEYVMj0Q4me11pBoLzfrQ.0

So we might need more retriggers on earlier pushes?

The leak stacks are a bit confusing; they point to JS things calling into a console API, but the JS is called from nsDocShell::InternalLoad, which appears to be from a call to shouldLoadURI(), which hasn't changed for a while... so I'm not sure what's going on. :-(

There are at least two fairly frequent leaks. One of them is the Mochitest plain 4, which maybe is happening in dom/security/test/general/, and then there's also the one happening in downloads directory, which is in Mochitest BC. I think it is the BC failure that has started happening fairly recently, and extremely often, so I would to look at trying to figure out what is causing that one, not the other one.

The leak stacks are a bit confusing; they point to JS things calling into a console API, but the JS is called from nsDocShell::InternalLoad, which appears to be from a call to shouldLoadURI(), which hasn't changed for a while... so I'm not sure what's going on. :-(

The individual leak stacks are basically irrelevant. If you look at a full log, something like 80% of the entire log is just leak stacks. This is a symptom of a leak where we are leaking like an entire DOM window, along with all of its elements and tons of JS stuff.

Continued retriggers: https://treeherder.mozilla.org/#/jobs?repo=autoland&resultStatus=testfailed%2Cbusted%2Cexception%2Csuccess%2Crunning%2Cpending%2Crunnable&searchStr=linux%2C18.04%2Cx64%2Casan%2Copt%2Cmochitests%2Ctest-linux1804-64-asan%2Fopt-mochitest-plain-e10s-4%2Cm%284%29&fromchange=b05abc0736ee1ca8b97c17dbc78c76b595193220&tochange=1a8d79d0832fed96b4df55d28afe3925f6d8414f

I think it would be good to focus on the Mochitest plain BC 11 failures, not the older Mochitest plain 4 failures, because it seems to be a more recent regression, and because it appears to comprise around 90% of recent failures in this bug.

Although looking at the retriggers, the m4 failure rate appears to be quite high as well, so maybe we need to figure that out, too.

Bug 1265637 might be the debug version of at least some of these leaks. Bug 1265637 comment 101 says "The recent occurrences after the dom/security/ mochitests ran start with bug 1629866 according to retriggers." dom/security suggests it could be the same thing as the M4 leak here.

I'm doing retriggers to try to figure out when the bc11 failure started, and I seem to have narrowed it down quite a bit: https://treeherder.mozilla.org/#/jobs?repo=autoland&tochange=c61770518fbbee43712a472b52ed1c05dd79c932&fromchange=50bc520a5d0ce6b2a22e8f390a302d08e09f8cfe&searchStr=linux%2Casan%2Cbc11&selectedTaskRun=cZqXNakeQTykhp9K_IsFXg.0

Specifically, so far I've found failures on this push: https://hg.mozilla.org/integration/autoland/rev/cbd35ab772537ead53ec64cc3783220a3e66b1be
but not this one: https://hg.mozilla.org/integration/autoland/rev/bf91e9e8455eda80299902401c930f085e85b002

That gets us down to a range of about a dozen pushes, and a good chunk of those can't possibly have caused a Linux BC failure.

Further retriggers and backfills: https://treeherder.mozilla.org/#/jobs?repo=autoland&resultStatus=testfailed%2Cbusted%2Cexception%2Csuccess%2Crunning%2Cpending%2Crunnable&searchStr=linux%2C18.04%2Cx64%2Casan%2Copt%2Cmochitests%2Ctest-linux1804-64-asan%2Fopt-mochitest-plain-e10s-4%2Cm%284%29&fromchange=8134bf0eafd704130d33b989eba69043551d60a2&tochange=1a8d79d0832fed96b4df55d28afe3925f6d8414f&group_state=expanded&selectedTaskRun=RKm4DLPiQFmtF9F0fkxtHg.0

Also might be appearing on bc10 and bc11 jobs, retriggered and backfilled as well: https://treeherder.mozilla.org/#/jobs?repo=autoland&group_state=expanded&resultStatus=testfailed%2Cbusted%2Cexception%2Csuccess%2Crunning%2Cpending%2Crunnable&searchStr=linux%2C18.04%2Cx64%2Casan%2Copt&tochange=46e56d5d462811d45a562c8c736a79ad287ff8dc&fromchange=70a4c6e9cf6e15f0f46a2fc831f3a36c98e48068&selectedTaskRun=AOjUkJ2gRr6Wf1NpwgDcuA.0

I think it is likely that bug 1629866 is the regressor for the plain M4 failure. I'll mark the regressor for the BC failure when I find it.

Based on this, I think that the regressor for the BC11 failure is bug 1606652: https://treeherder.mozilla.org/#/jobs?repo=autoland&searchStr=linux%2Casan%2Cbc11&tochange=fc5808ee37a18acef7ff69eba861ccc8f24c3ae2&fromchange=a34e77d6c3bf775acf9ad987e215038fb2edab72

Denis, could you take a look? Thanks.

Note that there was a single failure before that landed, but I did a half dozen retriggers and it didn't happen again, so it may have been a pre-existing very rare intermittent failure: https://treeherder.mozilla.org/#/jobs?repo=autoland&selectedTaskRun=XDKoY3MdST-Q6VLt5eVDWA.0&revision=5cff19bd3c534c55d3ef0070773a91f822135c60&searchStr=linux%2Cbc11

Peter, could you please look at the intermittent Mochitest 4 leak? This feels like it is probably the same issue as described in Bug 1265637 comment 101.

Thanks Andrew, taking a look asap.

Clearing my ni given we have regressors now...

Changing the ~LinkedList() assert to a MOZ_RELEASE_ASSERT, I can reproduce the same issue as bug 1265637 here and also gave me a useful traceback. There are some unused tasks remaining in the parseFinishedList_ for the JS helper thread when we call JS_Shutdown. This is to be expected since we are speculatively parsing scripts now, but any remaining preload scripts should be canceled during ~ScriptLoader() to clear this list out. Running this fix through some tests at the moment.

I've had some success with getting CC logs off of try for leaks I couldn't reproduce locally.

bug 1646793 has landed but there appear to still be bc failures. Denis, any ideas as to what may be causing that?

Hmm, I did confirm the bc11 failures were fixed with the changes in bug 1646793: https://treeherder.mozilla.org/#/jobs?repo=try&revision=34e69ad19905812597aee2e7075ebd5c379afcb3

Chunks (and which tests are in which chunk number) are not constant - they get re-done when tests are added/removed. For instance, the recent failures shown in orangefactor are for jobs in chunk 13, not 11.

The issue seems to be triggered in runs that include the browser mochitests in browser/components/downloads/test/browser/, and your trypush did not run those tests.

You can use a path param with mach try fuzzy to only run the relevant tests (ie ./mach try fuzzy browser/components/downloads/test/browser/).

Denis, do you have any updates on this? The failure rate here is still high with 177 total failures in the last 7 days: https://treeherder.mozilla.org/intermittent-failures.html#/bugdetails?startday=2020-06-21&endday=2020-06-28&tree=trunk&bug=1634641

Thank you.

I thought I found the issue, but it appears to only address the isEmpty asserts from bug 1265637 which appears to be a separate issue. I am still investigating this leak as my main focus, however. It is only reproducible on try for me so debugging has been a bit lengthy. I should also mention that the initial bug that regressed this is under a nightly only pref so this leak should go away in a release build.

I posted this in bug 1265637, but I'll post it here too since the bugs have become muddled. This was an existing leak, where we were leaking a ton of BrowsingContexts. Bug 1629866 made the BrowsingContext hold an additional object (ChildSHistory), and that made the leak worse, but it doesn't cause it. Somebody needs to figure out the existing leak.

The browser/components/downloads/test/browser/ failure seems to be almost (but not entirely) permanent at this point. I'm not sure if that's a change, but I've looked back to at least Tuesday and it has been that way.

The last time that directory didn't leak on m-c appears to be on Sunday: https://treeherder.mozilla.org/#/jobs?repo=mozilla-central&group_state=expanded&searchStr=linux%2Cbc%2Casan&revision=66013e166aa82f864889f51062944e5509f94b7c

The next m-c push it was failing: https://treeherder.mozilla.org/#/jobs?repo=mozilla-central&group_state=expanded&selectedTaskRun=Podwti3-RNyo-8UN93P8zg.0&searchStr=linux%2Cbc%2Casan&revision=921a30cac33b6d0760f318b6f1a2e3ce1bd687cc

Ok, that's not right. Going back further, it was still orange on m-c earlier than that.

Still not entirely sure where the leak is coming from, but it seems strongly tied to parsing "resource://pdf.js/build/pdf.js" off the main thread for whatever reason. It seems there is a race somewhere since subtle harmless changes can make the leak go away entirely. There are other scripts parsed omt with similar properties but it doesn't seem like parsing any of them introduces any leaks at all which is curious.

Over in bug 1609920, I think rpl found that browser_pdfjs_preview.js was the cause of the bc leak. We should disable that test with ASan, because this is failing 100% of the time.

https://hg.mozilla.org/mozilla-central/rev/f06c9a5fbd67

https://treeherder.mozilla.org/logviewer.html#/jobs?job_id=309460731&repo=autoland&lineNumber=20452 seems to be the same leak in m-bc running toolkit/components/certviewer/tests/browser/browser.ini , which doesn't appear to have anything to do with pdfjs ( https://searchfox.org/mozilla-central/search?q=pdf&path=toolkit%2Fcomponents%2Fcertviewer%2Ftests%2Fbrowser&case=false&regexp=false shows no hits).

There are also a large number of devtools test leaks. Are we any closer to figure out what is going on here, and/or is there asan-only debugging code we could add to get closer to figuring that out?

Bah, I noticed bug 1652126 too late - I'm guessing that is supposed to fix all of these?

(In reply to :Gijs (he/him) from comment #71)

Yes, I'm hopeful it should fix the leaks here and the asserts in bug 1265637. The leaks in m-bc look similar as well, so hopefully it should also fix those.

Denis, it would seem this is still happening despite bug 1652126 being fixed - can you take a look?

It may not be related. This intermittent failure signature is just what it looks like whenever we leak a lot of JS stuff. It looks like these failures are happening in mochitest-devtools-chrome-e10s-4, in the devtools/client/jsonview/test/ directory.

This bug failed 44 times in the last 7 days. Occurs on linux1804-64-asan platform on opt build type.

Marco:
Can you have someone take a look a this bug?

(In reply to Dorel Luca [:dluca] from comment #92)

Can you have someone take a look a this bug?

Unfortunately I don't manage resources, and thus I'm not sure who I may ask to. The most likely persons already investigated this earlier, per the previous comments.
I'm not sure why this is still under Downloads, when from the last logs it seems to be affecting a lot of other areas, many of the recent logs seem to point out to newtab tests, certviewer, devtools... It should be moved to either general or js, but that won't help figuring it out anyway.

At this point it's a more general intermittent leak that affects various tests, not just downloads, and that requires someone with deep knowledge of gc/cc to investigate (provided there's a decent way to reproduce it consistently, that doesn't sound like).

Andrew, do you have cycles to do any kind of digging here that could lead to identifying someone who could work on this? ATM it seems this is filed under downloads, but the failures are from devtools' json view, and new tab tests (browser/components/newtab), but I expect they're not actionable for engineers on either team right now - and it's not clear to me if they indicate issues with those components or their tests, or underlying issues in gecko/JS land that are exposed by those tests.

Going to clear some priority flags to make this bug slightly more accurately reflect what's going on.

Perhaps some of these are still lingering off thread parse tasks. bug 1652126 guarantees that cancelling a request is a successful, but there could still be some situations where cancellation does not occur before a shutdown and the parse tasks do not get cleaned up.

bug 1666724 seems to be one such case where shutdown happens but the off thread compilation was never notified and tries to dispatch a runnable during shutdown. I haven't been able to reproduce it, but I have a patch that will register a shutdown observer and cancel any active parses if called which hopefully fixes the problem and may also help here.

Yeah, hard to know what to do here. These failures look like they are pretty spread out across a variety of bc test suites, so reproducing this seems like it would be difficult. It does seem notable that these are exclusively bc and devtools tests. (I assume the devtools ones are actually bc.) Denis's theory that they could be related to off thread parse tasks sounds plausible.

leakcheck has been broken on Linux for a few months, so it is possible that that could be hiding this leak issue for non-LSan.

There's a lot of stencil stuff in the stack, but presumably we just leak that kind of stuff when we leak JS. It looks like this got worse in the last week or so of October. Ted, does that line up with anything happening with Stencil that you are aware of?

There are 58 total failures in the last 7 days on linux1804-64-asan opt

It looks like this may have gone away recently. Somehow. The failures in the previous comment are all from beta and ESR78.

The Bugbug bot thinks this bug should belong to the 'Core::JavaScript Engine' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

With 0 failures this can't be S2.

It looks like it has only failed on ESR78 for a long while, so I suppose we'll just wait out that branch being abandoned.

My theory was that it was Stencil related so I'll move it to JS.

Ah, I guess we did disable a test, so maybe that's hiding a failure.
