I think this patch truly is now ready for review with no failures on EWS. The red bubble on Mac seems to be due to some problem with the Mac EWS bot, not a problem with this patch.

We should probably get rid of FTP directory support at some point.  I don't believe we are using it anywhere.

What makes this assertion correct?  From looking at callers of this (of which there are only a few), this seems safe, but I think it would be better to pass contextElement in by reference to here.

> Source/WebCore/dom/DocumentFragment.cpp:91
> +    ASSERT(contextElement);

Same thoughts as above.

Good idea. Why didn’t I think of that?

I completely agree. I just tried to hold back and not do all the refactoring in one go.

Yes. Will do.

Turns out this one is correct and I changed the argument to Element&.

But this assertion is not correct, and I removed it.

This change made editing/pasteboard/drag-and-drop-objectimage-contenteditable.html time out:

EWS warned about this for the previous version of the patch, but it failed to build the  latest one because of some kind of gperf failure on WebCore/css/makeprop.pl. These build failures happen frequently, I wonder what's up with them.

OK. I’ll tackle that this evening. Would you be willing to put it on Skip for me until I get to it? I’ll make it my top programming priority, so should be done in a day or two at most.

[Alexey Proskuryakov]

Skipped it in <http://trac.webkit.org/r177913>.

[Darin Adler]

Fixed the regression and reenabled the test in <http://trac.webkit.org/r177951>.
