Description chaz.shrawder 2016-12-10 06:53:38 UTC
Below is a pretty basic description of what I've encountered. It's not something very large or complex, so I hope this is enough. Windows testing did not show this problem. 

If worker_request is null, the call fails and breaks a PostalMVC4 dependency. Returning false, as other calls in the class do, would prevent this behavior

GitHub file:

Line # as of  Jul 6, 2015:


public bool IsLocal {
	get {
                // throws NullReferenceException
		string address = worker_request.GetRemoteAddress ();

		if (StrUtils.IsNullOrEmpty (address))
			return false;

		if (address == "")
			return true;

		System.Net.IPAddress remoteAddr = System.Net.IPAddress.Parse (address);
		if (System.Net.IPAddress.IsLoopback (remoteAddr))
			return true;

		for (int i = 0; i < host_addresses.Length; i++)
			if (remoteAddr.Equals (host_addresses [i]))
				return true;

		return false;
