ArrayBufferView from TypedArray

[blois]

When running the html/xhr_test test, I'm seeing a warning in the console:

  ArrayBuffer is deprecated in XMLHttpRequest.send(). Use ArrayBufferView instead.

I converted the test from:
  xhr.send(data);
to:
  xhr.send(new Uint8List.view(data.buffer));

But still see the warning. What is the proper way to get an ArrayBufferView from a typed array?

This could be a duplicate of Issue #10136.
Since VM typed arrays implement TypedData (ArrayBufferView) and ByteData (ArrayBuffer), a validation test of the form (if (x is ArrayBuffer) .... ) will trigger when it should not.

Fixing issue #10136 is getting more critical.

Marked this as being blocked by #10136.

This looks like a problem in Dartium's XHR send:

http://src.chromium.org/viewvc/multivm/trunk/webkit/Source/bindings/dart/custom/DartXMLHttpRequestCustom.cpp?revision=1350

We're not testing for ArrayBufferView at all. Given issue #10136, we should test for ArrayBufferView before we test for ArrayBuffer here.

Taking a stab at this.
