This looks great.  I will need to read it again when I have less wine in my system. :)

We don't wrap to 80c in webkit.  We wrap for readability. :)

Looks like we need another round for style and for the 2 tests it fails.

We don't use const like this.  const& sure, but we don't generally use const for values.

Why does't this check renderer()->style()->resize() != RESIZE_NONE ?

Why doesn't this check RESIZE_NONE? It's the only case where we check canResize but not that. It doesn't seem like we should be resizing the layer if that style is set, and it would allow us to move the check into canResize.

[Christian Biesinger]

I was wondering that too. You're probably right and I should move that check into canResize(), so I'll do that.

Remind me why iframe is special here?  I guess FrameView's always clip so they just have "implicit" clip and don't set hasOverflowClip?

[Christian Biesinger]

Yes, that was my thinking. Should I add a comment to that effect?


(I also have a local patch to fix the LayoutTests changelog, but I was going to wait with uploading that until I have final review comments and bot results)

Comments about "why" are always good.  If you're uploading a new patch anyway that seems appropriate.

Thanks for taking this on.

What are you passing --binary to?  webkit-patch upload should do all the magic for you?

[Christian Biesinger]

I didn't use webkit-upload-patch for that last upload... maybe I should have, but it felt simpler to do it manually that time.

[Eric Seidel (no email)]

You might check out
Webkit-patch help -a
To see all the hidden commands. Upload is the all-sing-all-dance, but there may be more advanced/older commands which better fit your favorite workflow. :-)

Hard to say what exactly went wrong here.. Giving it another kick and hoping the patch still applies.
