[Bogdan Tara[:bogdan_tara | bogdant]]

The 31568 bytes leak seems to have started with the changes on bug 1603765.

Comment 3

[Nicolas Chevobbe [:nchevobbe]]

I'm not sure what's going on here.
In Bug 1603765 we split the big manifest had into 3 smaller ones.
So I guess this shifted something, somehow.
I'll investigate today.

Summary: Intermittent leakcheck ... → Perma Tier 2 Fission leakcheck ...
42 failures in 3773 pushes (0.011 failures/push) were associated with this bug in the last 7 days.

@ Bogdan, you changed this bug summary from "Intermittent" to "Perma", but there were only 42 failures in the last 7 days. Is this test failure really permanent? Does this affect both Fission and non-Fission tests? Or just Fission?

Also, do you when this DevTools test became tier 2? kmag says he thinks they used to be tier 1. We shouldn't downgrade Fission tests from tier 1 to 2, if possible.

(In reply to Nicolas Chevobbe [:nchevobbe] from comment #3)

@ Nicolas, do you have any updates?

kmag on the DOM Fission teams says he can try to reproduce locally.

This is perma-failing on mozilla-central, tier2. It doesn't run by default on integration, the failures classified there were from backfills.
I tried to look for when this got moved to tier2, however i didn't find that info.

Currently there are 19 total failures in the last 7 days on linux1804-64 debug and as Bogdan mentioned above, seems to be from bug 1603765 based on retriggers.

Comment 12

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

This started with the switch to Ubuntu 18.04. The report claims each console test creates a hidden windows and docshell. Is that true or is the suite dragging the leaked one along?

Increasing priority (from P5 to P3) because Andreea says this tier-2 test is perma-failing on mozilla-central.

[Andrew McCreight [:mccr8]]

It looks like devtools/client/webconsole/test/browser/browser_console_devtools_loader_exception.js is the leaking test, from looking at two logs. I can also reproduce it locally on OSX.

Marco, this DevTools test is reporting an intermittent leak when Fission is enabled. Can someone on the DevTools team please temporarily disable this test when Fission is enabled (with something like skip-if = fission && debug && (os == "mac" || os == "linux")) and then add fixing the leaks to your DevTools Fission backlog?

Comment 26

Thanks Chris. Moving the 'needinfo' to Alex to have a look at the test and any follow up bugs.

Comment 27

[Andrew McCreight [:mccr8]]

(In reply to Chris Peterson [:cpeterson] from comment #25)

Marco, this DevTools test is reporting an intermittent leak when Fission is enabled.

This isn't an intermittent leak, it is a permanent leak.

I looked at the cycle collector logs, and this is what was keeping one of the leaking XPCWNs alive:

0x12dba5980 [nsXPCWrappedJS (nsIConsoleListener)] --[mJSObj]--> 0x1a67715daec0 [JS Object (Object)] --[group_proto]--> 0x1a677157e780 [JS Object (Object)] --[destroy]--> 0x1e2332665140 [JS Object (Function - destroy)] --[fun_environment]--> 0x1a67715f1790 [JS Object (LexicalEnvironment)] --[**UNKNOWN SLOT 1**]--> 0x1e233265d380 [JS Object (Object)] --[define]--> 0x1a677159b510 [JS Object (Function - define)] --[fun_environment]--> 0x30642bfb5ac0 [JS Object (LexicalEnvironment)] --[jsmScope]--> 0x1a6771596780 [JS Object (Proxy)] --[proxy target]--> 0x1a677159f2c0 [JS Object (Object)] --[loader]--> 0x30642bf349c0 [JS Object (Object)] --[lazyServiceGetter]--> 0x30642bfb36c0 [JS Object (Function - defineLazyServiceGetter)] --[fun_environment]--> 0x30642bf784f0 [JS Object (LexicalEnvironment)] --[debuggerSandbox]--> 0x26734b8c300 [JS Object (Proxy)] --[proxy target]--> 0x26734b7a380 [JS Object (Sandbox)] --[C]--> 0x30642bf61460 [JS Object (nsXPCComponents_Utils)] --[js::GetObjectPrivate(obj)]--> 0x12c527040 [XPCWrappedNative (nsXPCComponents_Utils)]

This means that the object keeping all of the rest of the stuff alive is an nsIConsoleListener implemented in JS, and it is being held alive from C++. My guess is that this test is somehow failing to unregister a listener from the console service.

Comment 28

[Andrew McCreight [:mccr8]]

It looks like nsConsoleService clears out its references during shutdown (which is not entirely great...) so maybe it isn't the console service.

Comment 29

[Andrew McCreight [:mccr8]]

Ok, I looked at DMD, and it does seem like it is nsConsoleService::RegisterListener that is holding onto the XPCWJS. I'm not sure why it isn't getting cleared.

Comment 30

[Andrew McCreight [:mccr8]]

I see. nsConsoleService::Reset() clears the strong references from mMessages, but not mListeners. I'm not sure why that is. But anyways, this means my original theory, that something isn't unregistering a listener, is the likely explanation. I don't know know how this web console code is expecting to unregister.

Comment 31

[Alexandre Poirot [:ochameau]]

Thanks a ton Andrew for reducing that down!
We can probably have a look at DevTools/webconsole code.

But I wish we could debug the GC as you did it here.
Is there any documentation on how to see and identify GC paths like the one you copied in Comment 27?

Comment 32

[Andrew McCreight [:mccr8]]

The steps I used are documented here: https://developer.mozilla.org/en-US/docs/Mozilla/Performance/DMD/Heap_Scan_Mode

Though it did require a little hacking on the C++ because --mode=scan doesn't seem to work with mach mochitest.

Comment 37

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

Nicolas, can you provide an update about this permanent failure?

Comment 38

[Nicolas Chevobbe [:nchevobbe]]

Yes, I think I see why it's happening.
browser_console_devtools_loader_exception.js is testing the browser console, which connects to multiple targets (i.e. we're setting multiple event listeners).
But the test can run quite fast and then the destroy path does not care about removing the listeners (iirc, because the target are not fully "attached", even if the listeners are set).
I had a patch to try to wait properly for things, but still had intermittent failures. I can try to push the current patch, see if it does reduce the number of failure as a first step.

Attachment: Bug 1607569 - Fix leak in browser_console_devtools_loader_exception. r=ochameau.

In the Browser toolbox destroy function, we now wait for
any pending connection initialization promise.
In the test we close the browser toolbox at the end.
We also need to guard a few method in the connection proxy
to ensure the instances we use are still alive before using
them.

This test is still skipped for Fission on debug Linux:

Adding dt-fission whiteboard tag to DevTools bugs that mention Fission or block Fission meta bugs but don't already have a dt-fission whiteboard tag.

Nicolas, you fixed browser_console_devtools_loader_exception.js in this bug, but later on browser_console_webconsole_private_browsing.js has been disabled for similar reasons.
Do you think it would require a similar fix ?

(Moving the bug to the reserve list to give it slightly move visibility)
