(Core :: WebRTC: Networking, defect)

Attachment: testcase

If you create a DataChannel instance and specify {reliable: false} for the RTCDataChannelInit parameter, so internal attribute is not correctly updated as requested by the spec. It stays at true.

  var pc1 = new mozRTCPeerConnection();
  var channel = pc1.createDataChannel({reliable: false});
  alert("'" + channel.reliable + "' equals 'false'.");

The output here is: 'true' equals 'false'.

This actually changed recently per a recent IETF definition, but the spec isn't up to date.

See http://mozilla.github.io/webrtc-landing/DataChannel_changes.html.

= Invalid.

I think bug 855623 was the bug that changed this, but Randell can double check this.
