That's exactly right. Remember, GC is an interactive system; so if we're 
going to put together a flow-of-control demo, you either have to 
actually provide input as a user, or it has to be canned.

[Communicator-user] Simple Question: Toy Travel Demo

[Alexander D. <ali...@gm...>]

Hey guys,
I'm trying to rewrite the galaxy communicator stuff for a research project
for Alzheimer patients. I am simply trying to rewrite the included
generator.c to send back a stock response, but when I run the Toy Travel
demo, it fails. The only way I can make it work is if I rewrite the frames
file to reflect this stock response. My question is this: what is the role
of the "short-example.frames" file in the toy-travel demo? it looks like it
is a frames file which is faking the I/O to/from the various servers, but
this does not make sense to me. Could someone clarify?
Thanks

Now you're hurting my head.

This file is built when you compile the system, if you have Allegro
Common Lisp. See the documentation for ALLEGROBIN at

[Communicator-user] [PATCH] timed_tasks.c: don't sleep while holding a mutex

[David Huggins-D. <dhu...@cs...>]

Hi,

I've been having terrible trouble making brokered audio connections work
with threads.  When I try to create a proxy from a separate thread,
GalSS_ProxifyObjectType() blocks for an indeterminate amount of time,
often several seconds.

After tracing the code it appears that the problem lies in timed_tasks.c
- the mutex protecting the task queue is only ever released for a very
short amount of time, making it unlikely that the thread which is trying
to add the proxy task will ever get scheduled.  This problem is
exacerbated by the fact that the hub thread is calling select() (which
will sleep) while holding the mutex.

This patch fixes the problem while maintaining thread safety:

Boy, it's been a long time since I thought about this stuff.

If I recall correctly (and there's no guarantee I do), the servers must 
be declared, but they don't have to be available at startup. That is, 
you can either declare a server that the Hub contacts when it starts, or 
a server "prototype" for which the Hub sets up a listener for the server 
to contact it. Either way, the Hub must know about all the various 
server types when it starts up, via the Hub script.

Hello,

 

I was reading in
http://communicator.sourceforge.net/sites/MITRE/distributions/GalaxyCommunic
ator/docs/manual/advanced/scriptless.html that server declarations are
required in the hub program. Does this entail that it's not possible to
create new servers once the hub has started?

Hi -

If you send a message to the Hub, the Hub should report that it's 
received it, in its window. It should tell you what server it received 
the message from, etc., as shown in the documentation. You reference the 
unit tester in your subject line; is the tutorial not behaving as 
documented?

Hello folks --


   I'm using communicator for one of my project (a dialogue system),
and I'm having some troubles with getting it to run smoothly. The
system hung up randomly and I had a hard time to debug it. My first
question is when I send a message to Hub, how do I know Hub really
received the message? Or what mechanism is used in hub for this? 


Thanks.

[Communicator-user] Problems running 4.0

[Dave S. <sta...@bb...>]

I'm playing around with 4.0 on Windows and having some problems.  It's
been awhile, so pardon the confusion.  I execute the following setup:

set GC_HOME=C:\Communicator
set PM_DIR=%GC_HOME%\contrib\MITRE\tools\src\process_monitor
cd %GC_HOME%\test

and then invoke:

C:\Communicator\bin\x86-nt\HUB.exe -pgm_file multiply.pgm

No servers are running yet, but this shouldn't matter.  I get a dialog
box that says "HUB.exe has generated errors and is being closed by
Windows.  You need to restart the program. An error log is being
created".  So the hub is just crashing.  What am I missing?

Also, what happened to the "tools" sub-directory of MITRE/contrib?

Re: [Communicator-user] Festival/Unit Tester

[Samuel L. B. <sa...@mi...>]

Well, this explains a lot. The festival server distributed with the
Festival package is not a Communicator-compliant server, it's the
server side of the internal client-server Festival communication. In
order to use Festival, you need a Communicator-compliant Festival
client wrapper, such as the one that's distributed in CMU's
Communicator system or the one in MITRE's Open Source Toolkit,
available at the same location as the Communicator distribution.

If you can figure it out, please let me know how why you got confused,
and I'll fix the documentation someday :-).

Sam and Alan,
Sorry it's taken me so long to respond -- we're in the middle of midterms
right now.  Anyway, here's the full output of the unit tester:

(This is after starting first the festival server, then the unit tester,
then stopping the unit tester.)

As far as the program file goes, I'm a little confused. As far as I 
can tell, there's no place to specify the program file when starting the
unit tester as the hub.  Please let me know if I'm wrong about this.

And finally, do you know where I can find info on what kinds of frames the
festival server needs to send and receive?  I've been digging for awhile
with no luck.

Thanks,
Kate

   I'm not sure I can help with the communicator usage, though might,
   but if you send me the the start of the SIOD errors: you

Send it to both Alan and me. I'd want to see a dump of both the unit
tester and the festival server. 

Oh, actually, I already know what the problem is. I'm almost positive
that the problem is that the unit tester doesn't do brokering. This
isn't documented anywhere, I now realize - I simply forgot to mention
it, for which I apologize. I'm not sure how precisely the problem is
manifesting itself, but if you send me the Hub program file you're
using it'll probably be obvious to me immediately.

[Communicator-user] Festival/Unit Tester

[<ne...@ca...>]

Hello folks --

I'm using communicator for my senior thesis project (a dialogue system for
registering for classes), and I'm having some troubles with getting it to
talk to Festival correctly.
I can run Festival in command-line mode (as a server or not) without any
problems, and I can launch the process monitor with the unit tester and
Festival as a server.  I can then start the Festival server, but once I
start the Unit Tester, I get a long list of "SIOD error: unbound variable"
statements in the Festival window.  A couple of them are followed by
"handshake" or ":conn_type", but most don't say what variable they're
referring to.

I'm exploring various avenues to try to figure this out, but if anyone has
any suggestions that will narrow my search, they'd be much appreciated.

[Communicator-user] The final Galaxy Communicator update?

[Samuel L. B. <sa...@mi...>]

All -

After several months of postponed promises, it's become manifestly
clear to us here at MITRE that DARPA is not getting around to funding
a follow-on to the DARPA Communicator project, and we currently have
no other source of funding to continue development of the Galaxy
Communicator infrastructure. So:

(1) We have shut down bug...@li... and replaced it
    with the Sourceforge bug queue for the Galaxy Communicator
    project. 

(2) We have updated the docs for GCSI and OSTK to reflect this change,
    and released an updated patch for GCSI 4.0 and a new version of
    OSTK with these updates.

We will still attempt to reply to questions, but it's probably best to
direct them to this public mailing list.

We still believe the GCSI is a robust and useful software package, and
we continue to encourage you all to enjoy its benefits.

Sam Bayer

Re: [Communicator-user] GalaxyCommunicator in a PDA

[Samuel L. B. <sa...@mi...>]

   For a while now i've been working with the GalaxyCommunicator which
   is part of an essay i'm finishing. I've been searching in the web if 
   there has
   been any attempts of making a Galaxy Server in a PDA. As I haven't found
   any i was woudering if anyone has tried or even if you think it worths a 
   shot.
   If yes I would also ask if you have any advice of which pda application
   Development Tool to use (Linux).

   Thank you for your time,

   Rafael Aranha

Here at MITRE, we've played with running small Communicator-compliant
servers on Linux PDAs. We succeeded (you'll notice that there are
cross-compilation instructions for the StrongARM chip in the
installation documentation). One of the sites funded under the
Communicator program actually built a Communicator-compliant demo on a
PDA, using PocketPC, I believe; I don't know whether this required any
modification of the Galaxy Communicator system itself, because no
modifications were reported back to us.

So yes, it's possible. My own experience with Linux on StrongARM is
that it was a little bit of a pain, but perhaps no more of a pain than
Linux typically is. One thing you may not know: the StrongARM chip
doesn't have a floating point accelerator, so writing audio drivers
may be a little more challenging than usual. However, I know it's
possible, because another site produced a non-Communicator-compliant
audio front end on a PDA, which connected via a socket interface to a
Communicator-compliant system.

Hope this helps -

[Communicator-user] FATAL ERROR: Local thread storage is NULL in GalUtil_ThreadPushCleanup (Win32)

[<dir...@gm...>]

Hello, 

I keep getting the above mentioned error message when trying to send a frame
to the hub. 

Background:

I'm trying to wrap up an existing program as a hub server. For this purpose,
I fork a thread within a initialization routine called from that program in
order to start the server main loop, which looks something like that:

int mainServer()
{       
  GalIO_ServerStruct *server;   

  char *(argv[]) = {NULL};
  int argc = 0;

  server = GalSS_CmdlineSetupServer(argc, argv);

  if (!server) {
    GalUtil_Fatal("Failed to set up server!\n");
  }
  GalSS_StartAndRunServer(server);
  exit(0);
}

In the reinitialize dispatch function I create and store a copy of the
server_data pointer (GalSS_EnvCopy) for later use.  

I am able to send a frame to the hub within the reinitialize routine, but
later is does not work at all. 

Any suggestions for overcoming this problem are very much welcome.

Regards, 

dirk

Re: [Communicator-user] GUI java server

[Samuel L. B. <sa...@mi...>]

Hi Gies -

Writing UI elements ain't the simplest thing in the world,
unfortunately. The easiest thing to do is download OSTK-20020125,
which is the previous version of the Open Source Toolkit. In
gui_io/io_podium/java, you'll find a server which does something very
close to what you want. We removed it from the most recent version of
the OSTK because we didn't want to maintain parallel Python and Java
versions, but you're pointing out that it would be awfully nice to
have a simple Java UI example in the distribution. We'll keep that in
mind. 

Cheers,
Sam Bayer

[Communicator-user] GUI java server

[Gies B. <G.B...@le...>]

Dear fellow-developers,

Within an educational project at our department at the University of Nijmegen, I am
trying to write a GUI server in Java. The application should be able present a simple
form with just two elements: a prompt text and an input textfield. The application makes
a connection to a hub; as soon as a sentence has been entered, a message must be send to
a parser. Additionally, a language generator server must be able to send in a new prompt
text.

To me this demand looks quite basic. Yet, it has already been taking me a couple of days
to get this working and I'm still without success. An important question is: in what way
are the local server dispatch functions supposed to access the UI-elements? I tried using
the ServerUI class, but information how to use it (specifically the subclassComponent
field) is quite limited.

Does anybody have something similar lying around? Any tips? I will send my code so far on
request.

Thanks,
