Bug 91208 – Restructure V8Utilities::extractTransferables() with help of toV8Sequence()

• Component: New Bugs
• Status: RESOLVED FIXED

[Vineet Chaudhary (vineetc)]

With toV8Sequence() (r122555) now we can have generalised validation of the passed object for sequence type per WebIDL spec.
We can remove the specialised check for MessagePort from V8Utilities::extractTransferables() using toV8Sequence()

Is it OK to remove this part? I mean, the code might be:

  if (value->IsArray()) {
    v8::Local<v8::Array> array = v8::Local<v8::Array>::Cast(value);
    length = array->Length();
  } else {
    if (toV8Sequence(value, length).IsEmpty())
      return false;
  }

Though removing IsArray() check doesn't cause any behavioural change but having it will surely faster than every time calling toV8Sequence(). Thanks!!

Regarding failing perf test though I have rebased test expected but I really not sure if that is expected?

Just in case: "keep it as is" means please do not include the change in this patch.
