Most of these changes seem fine, but some do not (see inline comments). Also please fix the tab characters.

> Source/WebCore/html/shadow/MediaControlRootElementChromium.cpp:62
>  #endif
> +    , m_textTrackDisplay(0)

this should be inside the #if ENABLE() guard, not outside of it

> Source/WebCore/inspector/InspectorIndexedDBAgent.cpp:569
> +    , m_enabled(false)

I'm not sure this is correct - this bool doesn't seem to actually be used. maybe it should be deleted instead?

> Source/WebCore/platform/graphics/skia/ImageBufferSkia.cpp:130
> +    , m_resolutionScale(0)

i think 1 is a better value to initialize to

Yeah. Even I feel it should be deleted. So I made code changes accordingly.

jamesr@: Thanks for reviewing my code. I am not sure why the commit queue failed. Do I need to make any changes to the ChangeLog?

I think it picked up the wrong patch because patch set 2 wasn't marked "obsolete".  Will try it again.

Are you using webkit-patch upload to upload these patches? It takes care of many of these things for you.

actually i take that back - you need to have the "Reviewed by NOBODY (OOPS!)." line in this ChangeLog entry as well as the WebCore/ChangeLog one.
Comment 13 kmadhusu 2012-03-27 16:36:04 PDT
Oh okay. I didn't  use webkit-patch upload script. Can I modify the ChangeLog now to include that text?
Comment 14 James Robinson 2012-03-27 16:38:55 PDT
Yeah, just add those lines back and upload a new patch.
