The bufferedAmount read-only property on the TCPSocket object that populates navigator.mozTCPSocket by default triggers a null pointer exception in JS when called as such: navigator.mozTCPSocket.bufferedAmount Stacktrace: JavaScript Error: "this._multiplexStream is null" {file: "jar:file:///system/b2g/omni.ja!/components/TCPSocket.js" line: 197}]' when calling method: [nsIDOMTCPSocket::bufferedAmount]" nsresult: "0x80570021 (NS_ERROR_XPC_JAVASCRIPT_ERROR_WITH_DETAILS)" This is problematic when marshalling or inspecting the object.

Attaching a patch which fixes the problem, but I'm unsure what the default return value of the bufferedAmount property should be. I've assumed it's meant to be 0. I'm also unsure if this is the right way to solve the problem, so feedback is very welcome!

Comment on attachment 8392527 [details] [diff] [review] 0001-Bug-984595-Fix-null-reference-on-TCPSocket.bufferedA.patch This will likely be fixed by bug 885982, so cancelling review for now. Will revisit and check that it does when that bug lands and take appropriate action then.
