Future of MapTool?

[wolph42]

I *did* test upnp and came up with an error as reported earlier, so someone else will need to test this.

[JamzTheMan]

Sorry guys. Long time, no write. Life has been wicked lately (I got stuck in NYC during Sandy and I certainly have sympathy for those who are still stuck there without power or other basic necessities!)

To help prevent people from taking my name in vain too loudly, I've attached the fixed UPNP library source code (two JARs are inside, a "debug" and "nondebug" version).

I'm teaching a class this week and writing new lectures in the hotel each evening as I go along (this group of students is much more advanced than expected!) so no time this week. I'll try to allocate some time on Friday and/or this weekend to look into things and get some code committed.

Glad you made it out safe! That was one hell of a storm and there appears to be another one looming. Those poor people

Edit # 3: Can anyone test UPnP using what I shared above? Also, as it might be related, can you also post MT debug info? I'm curious if it still detects IGDs but fails to do so when attempting UPnP when starting a server, or is blind altogether.

Ok, latest JAR starts up ok (yea!) but I also got an error starting a server with upnp enabled. LMK if you need any other info or need to add additional debug-logs to the jar and rerun.

Edit: Lee, you may be able to test this if you have a second windows machine by turning on internet sharing as windows supports upnp. Also found the following but never used it. Bottom line, you may be able to emulate upnp at some level. http://miniupnp.free.fr/

Here's the patch for comparison. It removes the FTPCommand class and changes FTPClientConn to use sun.net.ftp.FtpClient directly.

The patch only changes behaviour used when updating an ftp based repository.

[Lee]

Yeah, consolidating the 2 is the way to go at this stage of 1.3. It's not as if anyone else will use FTPCommand as intended and extend on it; they can always extend the unified class. On my part, I just ironed out the creases to make it run, using the new convenience methods in place of the ones that stopped working as they are. Yours should go into Testing

Edit: Oh, and once you do put it in testing, we should clear the patches we put here to avoid clutter and confusion.
Edit # 2: @Jamz Thanks for the tip, and for the testing. Unfortunately, I'm currently on just this one laptop. At least it's known now that what's committed at the source wasn't the fix for UPnP.
Edit # 3: I took out my patch since it wasn't being reviewed. It was there only for academic interest anyway, and tiorthan's patch works just as well and is leaner.

A Google search for "nat-pmp java" brought up this page on SourceForge: http://sourceforge.net/projects/jnat-pmplib/

Since that library appears to be maintained we should look into using it instead of the sbbi library. If anyone wants to tackle an interface layer to allow this code to be used, I'd appreciate it! Note that the IGD library that is currently there is the older technique so I have no problem going with NAT-PMP (although a lib that supported both would be ultra nice!).

[Lee]

Since it seems we're open to using other libraries, I came across other UPnP libraries in Cling and weUPnP; both seem to be documented and active. Of the two, Cling sets the bar higher for itself, it seems.

Since we're also open to using other protocols, there's ice4j, IcedJava, and PJNATH; although the last one is C based suggested as JNI for usage.

Currently, I have my hands tied due to router problems. I was told we had an old AT&T router buried somewhere in the mound of junk we call a storehouse. When I feel up to it, I'll dig around in the hopes of finding it. I could write something one of these weekdays for one of these libraries, perhaps Cling as it seems the most elegant of the 2. Testing would have to be the problem of others, understandably. Perhaps, if one writes for NAT-PMP, it would then be trivial to combine the 2.

[Azhrei]

AFAIAC the "UPNP not working" thing is a bug and should be fixed for 1.3. It's important for it to work properly so that users will have a reasonably robust environment while work progresses on 1.4. Not having UPNP would be a real pain.

I don't want to go overboard on this, though. If we find something that works, great. I would rather not implement a library of our own if we don't have to! Ideally we'd have an abstract factory class that does the query using all known protocols, then instantiates a protocol-specific factory that can give us an an interface implementation. Something like...

Code: Select all

UPNPFactory[] uf = UPNPFactory.getInstance();  // returns one per router
UPNPInterface ui = uf[0].getInstance();        // pick the "best" router and use it
/* Then invoke methods of 'ui' to do the real port mapping work. */ 

The factory's getInstance() would query the local network and make a list of all available UPNP destinations. It returns a reference to all factories that know how to create protocol interfaces for each type of router. Then we invoke the getInstance() method on those factory objects to actually talk to the router and turn on/off the port mapping.

This gives us flexibility: we can talk to multiple routers using multiple protocols all at once. We don't really need that in 1.3 because we don't have the GUI to support it (allowing users to pick one interface from a list of interfaces, for example) but it's the Right Way(tm) to do it so that's the ideal implementation.

Hello all.
Just a poke to see how a Final Final version was going.

I want to also say that I came here today and posted a very upset post on the Java7 fix thread.
However, after reading this thread I have more hope for MapTool to become finished.

However, there was discussion in this thread about making the homepage more open to new people back in July and nothing has been changed.

Sep 3, 2011
First Ever Commercial Maptool Adventure - The Breaking of Forstor Nagar!

That's the last news entry.
The site looks dead. And with other products coming on strong, Roll20, EpicTable and others, we are losing the community.

I also think this thread should be in the announcements, or rather a new Future of MapTool starting with whatever the plan is at this time.

Those are my thoughts. From someone that had used MapTool from March 2008 until Oct 2012. I would like to come back soon.
