ISSUE-104: Value of progress event total when it cannot be determined
http://www.w3.org/2005/06/tracker/webapi/issues/104 Raised by: Charles Mccathienevile On product: Progress Event What should this be. I don't think we should set a very big number and hope that nobody needs to deal with that. I am more inclined to set it at zero. If you get zero, either the thing is empty or undefined - still not ideal. If you leave it as undefined, then people will have to check lengthComputable before they know if the value is meaningful. The alternative is to make it a negative value but I am not mad keen on doing that.
