Device UUID storage

[Mingfeng Wang <mi...@gmail.com>]

Hey,

    Now the Device UUID is saved in localStorage of html5 for Windows8, so
it is the same if all the projects are in the same domain.
    I want to use a file instead of localStorage, is it necessary? And
where can I save this file?

Hi,

Sorry to jump in without background, but on Win8 I think it would make more sense to use the built-in hardware ID that WinRT provides, as below, rather than using createUUID to demand-create a device ID. (The hardware ID would obviously survive a localStorage reset.)
private string GetHardwareId()
{
var token = HardwareIdentification.GetPackageSpecificToken(null);
var hardwareId = token.Id;
var dataReader = Windows.Storage.Streams.DataReader.FromBuffer(hardwareId);

byte[] bytes = new byte[hardwareId.Length];
dataReader.ReadBytes(bytes);

return BitConverter.ToString(bytes);
}

I've created a Jira item to this effect. 
https://issues.apache.org/jira/browse/CB-1702


Hopefully I'm not missing something! As I suggest, I'm new to any prior discussion.

Thanks,
Matt
