:kmag, I see you were the author of the patches- this wasn't seen as we failed to surface leaks (bug 1325148)- so we can whitelist this in the meantime- can you take a look at this bug when you get some time?

I am not sure if webextensions is the right component, toolkit/extensions didn't map to anything specific.

the patches in bug 1325158 have landed a few days ago and we still get a lot of failures for this bug- :kmag, can you take a look at this when you get some time?

It doesn't look like these failures have anything to do with the toolkit/components/extensions/test/mochitest directory.

these seem to be in a variety of directories just looking at some of the more recent ones:
layout/forms/test
dom/tests/mochitest/webcomponents/
toolkit/components/startup/tests/browser

The leaks from the push you mentioned in comment 1 should be fixed. The rest, I don't have anything to do with, so this probably belongs in a different component now.

At the moment, I see two likely possibilities:

1) The LoadModule leak suppression[1] is no longer working reliably, because it's more than 5 frames deep, and the unwinder does not consistently unwind that far:

  Indirect leak of 520 byte(s) in 5 object(s) allocated from:
      #0 0x4b24ab in malloc /llvm/projects/compiler-rt/lib/asan/asan_malloc_linux.cc:52:3
      #1 0x4e113d in moz_xmalloc memory/mozalloc/mozalloc.cpp:83:17
      #2 0x7f9c46abedba in operator new obj-firefox/dist/include/mozilla/mozalloc.h:194:12
      #3 0x7f9c46abedba in NS_NewBackstagePass(BackstagePass**) js/xpconnect/src/XPCRuntimeService.cpp:185
      #4 0x7f9c46a059a2 in mozJSComponentLoader::PrepareObjectForLocation(JSContext*, nsIFile*, nsIURI*, bool, bool*) js/xpconnect/loader/mozJSComponentLoader.cpp:559:14
      #5 0x7f9c46a02188 in mozJSComponentLoader::ObjectForLocation(ComponentLoaderInfo&, nsIFile*, JS::MutableHandle<JSObject*>, JS::MutableHandle<JSScript*>, char**, bool, JS::MutableHandle<JS::Value>) js/xpconnect/loader/mozJSComponentLoader.cpp:683:26

Something may have recently changed to influence that. Although, I don't understand why we're ignoring these leaks, since I'd expect us to clear the module cache at shutdown. Except, well...

    // Modules are intentionally leaked, but still cleared.

2) There's some issue with XMLHttpRequest objects in module scopes. All of the leak reports I've seen include XMLHttpRequest prototype chains, particularly the EventTarget classes, so there may be some faulty memory management there.

I looked over all of the failures in comment 13, and they all had a ton of stuff that looked like the JS engine leaking stuff, and they (almost) all had XHR stuff in there, like you said. I'm not sure what you mean about 1) in comment 14, but those little component loader leaks shouldn't result in this total leakage of JS engine stuff. We have a number of non-LSan leaks that look like they are XHR related (such as bug 1325438) so this is presumably just the LSan variant of that.

Depends on: 1325438
No longer depends on: 1325158

Yeah, I dug through the code some more and came to the conclusion that we shouldn't actually be leaking any JS objects from the component loader. The comments are just a bit incomplete/misleading.

It looks like one of the fixes in another bug has solved this intermittent leak.
