Posted patch Revise lifetime management (obsolete) — Splinter Review
Addresses feedback from an IRC discussion with smaug. Changes:

Disconnect() during unlink now called before clearing mOwner.
IntersectionObserver keeps a string reference to nsDocument.
String pointers to IntersectionObservers moved from nsDocument to Element.

Bug 1337936 - (intersection-observer) Revise lifetime management.

https://reviewboard.mozilla.org/r/110896/#review112626

Could I see the patch with traversing fixed.

::: dom/base/DOMIntersectionObserver.h:119
(Diff revision 1)
>    }
>

This is most probably the right document, even though the spec is unclear
https://github.com/WICG/IntersectionObserver/issues/195
and 
https://github.com/WICG/IntersectionObserver/issues/197

No need to change anything, spec just need to be fixed.
But worth to keep an eye on the spec bug. It may cause some changes.

::: dom/base/DOMIntersectionObserver.cpp:194
(Diff revision 1)
>    if (mConnected) {
>      return;

Please null check mDocument, just to be safe if this code runs after unlinking.
(unlinking doesn't technically mean deleting anything)

::: dom/base/DOMIntersectionObserver.cpp:210
(Diff revision 1)
>    for (auto iter = mObservationTargets.Iter(); !iter.Done(); iter.Next()) {
>      Element* target = iter.Get()->GetKey();

>    mObservationTargets.Clear();
> -  if (mOwner) {
> +  mDocument->RemoveIntersectionObserver(this);

null check here too

::: dom/base/FragmentOrElement.h:351
(Diff revision 1)
>      RefPtr<CustomElementData> mCustomElementData;
>  
>      /**
>       * Registered Intersection Observers on the element.

> -    nsDataHashtable<nsPtrHashKey<DOMIntersectionObserver>, int32_t> mRegisteredIntersectionObservers;
> +    nsDataHashtable<nsRefPtrHashKey<DOMIntersectionObserver>, int32_t>

You need to now traverse and unlink mRegisteredIntersectionObservers.
I guess unlinking does happen already, but traversing is missing.
Add traversing to FragmentOrElement::nsDOMSlots::Traverse ?

::: dom/base/nsDocument.cpp:12613
(Diff revision 1)

Nothing in Update() can cause scripts to run? Like, layout isn't flushed, right?

just
if (mDocument)

ditto

ah, indeed, we want the key to be traversed.

Please move 
NS_CYCLE_COLLECTION_NOTE_EDGE_NAME(cb, "mSlots->mRegisteredIntersectionObservers"); to be right before NoteXPCOMChild, so that it gets called before every entry.

http://searchfox.org/mozilla-central/rev/59cd73fbfa14384a81a4e3eb17d3881b372702c4/dom/base/FragmentOrElement.cpp#1967 is kind of similar example

could you use MOZ_ASSERT here

Backout by archaeopteryx@coole-files.de:
https://hg.mozilla.org/integration/autoland/rev/6e1c2cb7b5ba
Backed out changeset 5f93d62d9229 for asserting in crashtest 869038.html. r=backout
Ah, this RefPtr<DOMIntersectionObserver> observer = iter.Key();
Must use DOMIntersectionObserver* there, but whether hashtable iterator let's one to access it without
creating temporary RefPtr is unclear to me.


FWIW, I do expect that one has used the patches in a debug build before review requests ;)
Mh, for some reason I was and am not able to reproduce this. I did use the patch in a debug build. Furthermore, I can't see why 869038.html would run into this, the tastable shouldn't contain anything in that case...
Flags: needinfo?(tschneider)
ok. Anyhow the issue is that traverse shouldn't use RefPtr/nsCOMPtr, since those change refcnt.
Yeah, we do that correctly when unlinking. Will update the patch.
