Problem with 1.2.4

ThomasLund · Post by **ThomasLund** » 04 May 2010, 20:47

Hey,

Your code is totally correct. But it also suffers from the same Mono bug if you try to run that in the API. At least it throws the exact same error here when I paste that in after closing tab and trying to connect again.

(Also beware that it might look as if it all works if you run bluebox - the bluebox lookup seems to work correctly with hostname lookup)

Thread about the bug from the Unity forums:
http://forum.unity3d.com/viewtopic.php?t=13483

As you can see I was fooled by some small tests I made into thinking it was fixed - and thus put it into the API 1.2.4

In the short-term I'm fine with IPs (it has been so long now we're used to it -- I didn't even remember that GetHostEntry() was a problem!

The main thing was preventing the lockout on those browsers.

Thanks!

I have the same problem, and applying the fix from the code snippet to force SFS to NOT use DNS resolution works... kind of. But a different error right afterwards still prevents Mac Firefox from connecting properly.

I added a few debug logs to the SFS CSharp API to see what was going on, but I'm still puzzled - it seems to be another problem specific to Mac Mono. Basically, it looks like the function GetString(XmlNode, string) from XmlUtil.cs, when called from XmlReceived (SmartFoxClient.cs), throws an exception it's not supposed to throw. I added a "catch (Exception e)" in XmlReceived to see what was going on. Here's what I get from DebugMessage on the Mac Firefox webplayer, with lines starting with "###" being log additions of my own:

Any idea on how to prevent this?

I tested the fix posted in Firefox on the Mac - and it works here. So I dont know what problem you run into.

Can you post some client code (or PM it to me)

PM sent.

Edit: Actually, here's a way simpler test case I just found to replicate that problem. Tag this in SmartFoxClient.cs:

Code: Select all

public static string DEBUGTEST(string msg)
{
	string handlerId;
	try
	{
		XmlDocument xmlData = new XmlDocument();
		xmlData.LoadXml(msg);
		handlerId = XmlUtil.GetString(xmlData, "/msg/@t");
	}
	catch (Exception e)
	{
		return e.ToString();
	}
	return handlerId;
}

Then call it somewhere like this in Unity:

Code: Select all


    private string debugLog = "";
    void OnGUI()
    {
        if (GUI.Button(new Rect(120, 230, 100, 25), "DEBUGTEST"))
        {
            string s = SmartFoxClient.DEBUGTEST("<msg t='sys'><body action='apiOK' r='0'></body></msg>");
			debugLog += "\n>> " + s;
        }

        GUI.TextArea(new Rect(10, 260, Screen.width - 20, Screen.height - 280), debugLog);
    }

In most cases, when you click DEBUGTEST it'll just print out "sys", which is correct. But in Mac Firefox webplayer it'll print out this:

Code: Select all
