Bug 6471 – Assertion failure inside setInnerHTML logging into AOL's webmail

• Status: RESOLVED
• Resolution: FIXED
• Component: DOM

[John Sullivan]

To reproduce:

1. Go to http://webmail.aol.com
2. Log in with a screen name and password

When the subsequent page is almost finished loading, it fails this assertion:

...WebCore/khtml/xml/dom_nodeimpl.cpp:1228: failed assertion `!attached()'

Here's the backtrace:

I don't know if this is a regression because I don't have an old debug version to test against. I also haven't 
tested what happens on a deployment build. But since AOL is an important site, and this might be a crash 
on a deployment build, I'm setting the priority to P1. If this turns out not to have any visible symptoms on 
a deployment build, it can be set back to P2.

[Darin Adler]

John, can you still reproduce this?

[John Sullivan]

I don't currently know an AOL account name + password -- I was helping a family member when I ran into this originally. I'll try to get one so I can test this soon, but anyone else who has an AOL account could try in the meantime.

[John Sullivan]

I have obtained an AOL login, and the assertion still fails.

[John Sullivan]

I tried on a tip of tree Release build, and there's no sign of trouble on the site. So maybe this isn't really p1-worthy? Only someone who knows what that assertion is all about would know for sure.

[Darin Adler]

The assertion does reflect a relatively-serious problem; the attach code is not equipped to do the right thing on an already-attached DOM node. I'd like to see a reduction!
