+ - fix http://bugs.webkit.org/show_bug.cgi?id=16332
+ ObjC DOM exception object descriptions should include the exception name
+
+ * WebCore.pro: Added ExceptionCode.cpp.
+ * WebCore.vcproj/WebCore.vcproj: Added ExceptionCode.cpp.
+ * WebCore.xcodeproj/project.pbxproj: Added ExceptionCode.cpp.
+ * WebCoreSources.bkl: Added ExceptionCode.cpp.
+
+ * bindings/js/kjs_binding.cpp: (KJS::setDOMException): Moved the code to decompose an
+ ExceptionCode into ExceptionCode.h/cpp -- getExceptionCodeDescription. Also removed
+ the many unneeded includes that were here. Had to keep one special case here, for
+ SECURITY_ERR.
+
+ * bindings/objc/ExceptionHandlers.mm: (WebCore::raiseDOMException): Changed to use the
+ new getExceptionCodeDescription function so that this shares the exception name
+ information that was previously only available to JavaScript.
+
+ * dom/ExceptionCode.cpp: Copied from bindings/js/kjs_binding.cpp.
+ (WebCore::getExceptionCodeDescription): Added some assertions, and made the function
+ handle exception names in a slightly more robust way that is not subject to integer
+ overflow. (Not a real world issue since we should never receive a bad exception code.)
+
+ * dom/ExceptionCode.h: Added the ExceptionCodeDescription struct and the
+ getExceptionCodeDescription function.
+
+ * svg/SVGException.h: Added a missing #include and got rid of some comments. Some of
+ the comments were mildly helpful, but others were incorrect. This now matches the other
+ exception-related headers such as RangeException.h.
