Seems like you need to add the new generated files.

Why throw away the return value? Why not return it?

Please use single quotes.

Please add tests that show that your new code works. (And make sure you didn't break any existing tests.)

Should be "SetUpAcceleratedCompositingPort", with a capital "U".

Doing the cast once and storing the result in a local variable would be nicer.

It would be nice to add the names of functions you changed in messages.py.

I still think a local variable with type CacheModel would be better.

Hey, you shouldn't have commit it, because Qt EWS bubble is red.
It wasn't a fair play ...

Sorry, but I couldn't figure out how to make it work on Qt.  We have a DerivedSources.make file that the Qt build does not seem to be using.  If adding stuff to the project is prohibitively hard, it is likely that things will break.

I prefer poking our WebKit2 guys and ask them to fix Qt 
build system instead of breaking Qt buildbots and EWS.

Next time, please cc Zoltan ([e-mail]), Balazs 
([e-mail]) and Andras ([e-mail]), they
can help you with fixing Qt-WebKit2 build system.

Fix landed in http://trac.webkit.org/changeset/69046
