The email address needs to be fixed.


WebCore/ChangeLog:8
 +          No new tests.
This should explain why no new tests were added. For example:
"No functionality change so no new tests."


WebCore/html/BlobBuilder.h:38
 +  #include "PlatformString.h"
Actually why is PlatformString.h included? (Can't a forward declaration for String suffice?)


WebCore/html/BlobBuilder.h:41
 +  #include <wtf/text/CString.h>
I believe you're including this due to the destructor needing it. If you explicitly define the destructor for BlobBuilder or even ~StringBlobItem and put it in a cpp file, then this include shouldn't be needed.

But this header already "#include BlobItem.h" which "#include <wtf/text/CString.h>", so it is unclear why this is needed to fix the build.


WebCore/html/BlobBuilder.h: 43
 +  class ExceptionCode;

Typically Exception code is defined like this:
  typedef int ExceptionCode;
and ExceptionCode.h isn't included. (Also if you add this line, it should come after the class Blob; forward declaration.)

Thanks for reviewing; the patch was a bit rough.

Fixed.

>  +  #include "PlatformString.h"
> WebCore/html/BlobBuilder.h:41
>  +  #include <wtf/text/CString.h>

Both lines weren't necessary.  Removed them and added a forward declaration for String.
(I had needed to include wtf/text/CString.h because I had included PlatformString.h that wasn't really necessary.)

Right, the forward declaration actually didn't work (so I had removed the line and added '#include "BlobBuilder.h"' in the previous patch).

I replaced the line with a typedef.
