Please refer to bindings/v8/Dictionary.{h,cpp}.

(3) Modify JSDictionary::tryGetPropertyAndResult(..., bool) to support the last bool argument. If it is true, check undefined or null.

If it is true, check undefined or null. Thanks for the review, Kentaro. I just submitted a patch which is simpler and not changing any existing code of JSDictionary except the new added getWithUndefinedOrNullCheck().

Comment on attachment 145754 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=145754&action=review The patch looks OK. > Source/WebCore/ChangeLog:8 > + No new tests, idb not working for JSC yet. Did you manually confirm that getWithUndefinedOrNullCheck() works as expected? (You do not need to add a test, but might want to somehow confirm that it works.) > Source/WebCore/bindings/js/Dictionary.h:64 > + bool getWithUndefinedOrNullCheck(const String&, String&) const; Nit: getWithUndefinedOrNullCheck(const String& propertyName, String& value) would be better to distinguish variables. WebKit omits an argument name only if it is obvious.

(You do not need to add a test, but might want to somehow confirm that it works.) Yes, of course. I manually tested with correct value, null, undefined, no property, etc. All work as expected. >> Source/WebCore/bindings/js/Dictionary.h:64 >> + bool getWithUndefinedOrNullCheck(const String&, String&) const; > > Nit: getWithUndefinedOrNullCheck(const String& propertyName, String& value) would be better to distinguish variables. WebKit omits an argument name only if it is obvious. Ok, I can add that to make it clear.
