Comment 3

[Nika Layzell [:nika] (ooo, ni? for response)]

This directory appears to already have a ton of lsan ignores, including PLDHashTable::Add (https://searchfox.org/mozilla-central/rev/54f965e51e4f77866bec42737978d40d4c1fdfc5/testing/web-platform/meta/service-workers/service-worker/__dir__.ini#2). I'm guessing that the changes I made changed the behaviour in this test enough that the hashtable decided to shrink it's allocation at some point, meaning that the leaked allocation's stack changed, and stopped being ignored.

The correct fix would be to fix the mountain of leaks which are apparently occurring here, but the easiest is probably to just add the new leak signature to the list and avert our eyes.

Comment 4

[Nika Layzell [:nika] (ooo, ni? for response)]

I have a feeling that we're probably going to (or are already) run into situations like this frequently when changing code in directories with mountains of lsan exemptions. Is there something better we can do than just add more overly-general exemptions like PLDHashTable::ChangeTable?

Comment 5

[Nika Layzell [:nika] (ooo, ni? for response)]

It seems like this might be the same issue as bug 1631819, as this directory should perhaps be completely excluded from lsan leak checking.

Comment 6

[Jens Stutte [:jstutte]]

(In reply to :Nika Layzell (ni? for response) from comment #5)

It seems like this might be the same issue as bug 1631819, as this directory should perhaps be completely excluded from lsan leak checking.

I assume that it is not a Service Worker problem then? Thanks for looking into it!

Comment 7

[James Graham [:jgraham]]

Yeah, I don't have a good suggestion in the short term other than to change the exclusion rules. I guess I can look at adding lsan-disable: true or something as an option in the ini files.

Hi Nika! As bug 1631819 has been resolved a while ago but we still see this here: any other suggestions?

Comment 22

[Nika Layzell [:nika] (ooo, ni? for response)]

This particular WPT from my quick search already has a ridiculous number of lsan suppressions set up on it: https://searchfox.org/mozilla-central/rev/ab81b8552f4aa9696a2524f97fdfeb59d4dc31c1/testing/web-platform/meta/html/semantics/embedded-content/__dir__.ini#1

This already includes suppressions in PLDHashTable such as PLDHashTable::Add which would normally suppress hashtable leaks like this one. This particular leak seems to be one caused by a slightly different hashtable relocation code path. I'm guessing non-determinism is causing the stack for the hashtable's buffer leak to change intermittently, meaning that this is the same issue as the existing suppressed leak.

The proper fix here is probably to figure out why we're leaking when running these tests, and fix that issue, but the easy one is to add another suppression to the megalist.

[Andrew Sutherland [:asuth] (he/him)]

Plan is to disable the LSAN at a directory level based on pragmatic concerns and the general low data-structure churn of ServiceWorkers in steady-state that would mitigate any worst-case scenario. Needinfo to do that.

I assume, this is still the plan here. Yaron, moving the ni to you, but not for immediate action.
