Created attachment 372485 [details] [diff] [review] partial patch, updated attachment 309723 [details] [diff] [review] basically still applied, except for some whitespace-only changes that we're better off without anyway. I also changed a drop of commenting-out into removal. This fixes bug 420670. Sayre, was there any reason you hadn't requested review on this back when you wrote it?

(In reply to comment #3) > > Sayre, was there any reason you hadn't requested review on this back when you > wrote it? I think it's because I couldn't actually show improved CC behavior. I assumed it was docshell's alleged thread safety preventing adequate collection. But since you find it fixes bugs, we should probably take it.
So I can't reproduce the testing that I did a few days ago that shows it fixes bug 420670. But I *can* reproduce that this *plus* bug 488799 (add editor transactions and transaction manager to cycle collector) fixes bug 420670. And I tried it about 3 times both with and without the patch this time. That said, the above patch also makes crashtests crash. I'll post a patch with the fix; nsHTMLEditRules derives from nsTextEditRules but (without my revision) didn't forward to its QueryInterface. My patch makes the QueryInterface implementation forward (and thus get the cycle collection helper and cycle collection isupports entries) and also switches the canonical nsISupports pointer to the forwarded one.

Comment on attachment 373270 [details] [diff] [review] partial patch, udpated to fix crash >diff --git a/editor/libeditor/text/nsTextEditRules.cpp b/editor/libeditor/text/nsTextEditRules.cpp >+NS_INTERFACE_MAP_BEGIN_CYCLE_COLLECTION(nsTextEditRules) >+ NS_INTERFACE_MAP_ENTRY(nsIEditRules) This is missing the entry for nsISupports. Adding unlinking always makes me nervous in case we end up executing code that didn't expect the pointers to be null. We'll wee how it goes :-).
Created attachment 376341 [details] [diff] [review] pre-patch This fixes the crashes I was seeing on mochitests on Mac only (why Mac only? maybe the ordering of malloc influencing the ordering of Unroot?). In addition, I added the following two lines to the main patch: + if (tmp->mRules) + tmp->mRules->DetachEditor(); in nsPlaintextEditor's unlink method.
