[Orbit-python-list] stuck

[Frank R. <Fra...@we...>]

All,

I got stuck because I cant persuade python-orbit to use INET instead of
UNIX-sockets, and I cant find a tiny C example that shows me how to
create a server. 

please, perhaps someone can help me:

1.) Tell me, why the attached python server does not produce IOR with
INET profile when started as:
./test-server.py -ORBIIOPUSock=0

2.) Or give me a small example server in C that can be compiled doing
"configure" "make", and when running produces IOR with INET profiles.

currently I am using ORBit-0.5.8, RH7.1-i386

As long as I dont have a running server producing INET-profiles, I cant
go on.

Cheers, Frank

Are you free to edit orbitrc? You can supply a file like:

- orbitrc --- cut here ----
ORBIIOPIPv4=1
- orbitrc --- cut here ----

and stick it in /usr/local/etc/orbitrc or whereever it is that your system
searches by default (could be /etc/orbitrc on other systems IIRC).

Well, don't you need IIOIPv4 too?

Hey, don't hesitate to write. We don't have a lot of traffic, but it's
supposed to be a friendly list.

Take care,

This works, but I assume, after re-login, that the entire GNOME desktop
is using this setting now.

I did try 
./test-server.py -ORBIIOPIPv4=1 -ORBIIOPUSock=0
and also
./test-server.py -ORBIIOPIPv4 1 -ORBIIOPUSock 0

both did not work (orbit-python 0.3, ORBit-0.5.8)

thanks, it was a prompt help :)

As the applications start, actually, since ORBit only reads this at
startup.

Hmmm. Well, I assume you are passing sys.argv on to ORBit, which means
it's ignoring the flags. I'll look into orbit's code... Hmmm! Heh, we have
a bug in ORBit-Python (Tack, what about those zero bugs there?). Try this
patch -- damn, sourceforge is offline so no patch is possible. Okay try
doing this:

-- line 56 in CORBA__ORB_init() --

    for (i = 1; i < argc; i++) {

-> swap

        PyObject *o = PyObject_Repr(PyTuple_GetItem(orb_args, i - 1));

-> for

        PyObject *o = PyObject_Str(PyTuple_GetItem(orb_args, i - 1));


        argv[i] = g_strdup(PyString_AsString(o));
        Py_DECREF(o);
    }

-- line 61 --

PyObject_Repr adds single quotes, and is wrong. Using _Str() has corrected
the problem here, providing nice handling (this was a bug I ran into a
year ago but was too clueless to fix, how funny.)

BTW: I very commonly use gdb to track down this sort of problem and since
a few people here might want to use it with python, here's a tip. Start
python with a "gdb python" and in your script, add the lines

import signal, os
os.kill(os.getpid, signal.SIGINT)

where you want it to stop, and "r foo.py". The script will stop at that
point, and you can "break" inside loaded modules and so forth.

Take care,

Frank, Tack, the patch that fixes this bug has been checked into cvs.

A question for the ORBit ninjas:

I would like to provide a test-script for the test-suite so we guarantee
this works. Is there a way to query the CORBA orb to know what parameters
are currently active in a session?
