I should have said this, but my review is basically complete. (The test is involved and I likely need to spend more time and brain power there but I'm done with the code.)

There are other conditions in these series of if .. else .. that do not end with a return (see e.g. 'if(value->IsString())' branch above). I bet this can be beautified, but not in this patch.. >> Source/WebCore/bindings/v8/SerializedScriptValue.cpp:1174 >> + else if (V8ArrayBuffer::HasInstance(value)) { > > No { here due to single line statement. > > And don't have an else if the condition ends with a return. First part - Done. Re return: see prev. comment. >> Source/WebCore/bindings/v8/SerializedScriptValue.cpp:2145 >> + OwnPtr<ArrayBufferContentsArray> contents = adoptPtr(new ArrayBufferContentsArray(arrayBuffers.size())); > > We really should have a static create method on Vector. Not in this patch - what do you think? Although with all the typedefs it will be really hard to find all occurrences of this... >> Source/WebCore/bindings/v8/SerializedScriptValue.cpp:2153 >> + return PassOwnPtr<ArrayBufferContentsArray>(); > > Doesn't return 0 work? Or perhaps nullptr? nullptr works - thanks! >>> Source/WebCore/bindings/v8/SerializedScriptValue.cpp:2154 >>> + } >> >> Weird issue here with half being neutered if an array buffer list more than once. > > I should have said this, but my review is basically complete. (The test is involved and I likely need to spend more time and brain power there but I'm done with the code.) Great catch - thank you very much!

I bet this can be beautified, but not in this patch.. Ok, I get it. I was suggesting introducing a bug... whoops. > >> Source/WebCore/bindings/v8/SerializedScriptValue.cpp:2145 > >> + OwnPtr<ArrayBufferContentsArray> contents = adoptPtr(new ArrayBufferContentsArray(arrayBuffers.size())); > > > > We really should have a static create method on Vector. > > Not in this patch - what do you think? Agreed. I should have been more clear. Looking over the tests...
