[Orbit-python-list] Orbit-python and threading?

[Marijn V. <ma...@me...>]

Dear listers,

I am trying to get some program to work with python-orbit. Because I
need it to do some more work besides just waiting for corba requests
to come in, and i didn't see any "idle" hooks (ala gtk.py), My
solution is to dump the Orbit run() in it's own thread, while the
rest of the processing goes on in the mainthread.=20

Anyway, a strange thing happens, when I do that orb.run() the
application blocks (surprise!) nomatter that it's running in it's own
thread. If I replace the orb.run() with something like
time.sleep(largenumber) the threading works as expected.  I don't
really know what the cause of this is, or what to do about it. Any help
would be greatly apriciated.

What am I doing that i shouldn't? And if i can't mix orb.run() with
threads, how do i do some processing while orb.run() is just blocking
waiting for requests?=20

I included the most relevant source snippit, maybe i am doing
something very wrong, somehow...

Regrads,
	Marijn.

--- Here's the code that does the threading:
"sim" and "user" are two objects that hold the data the server has to
work with and "lock" is a global lock so that the implementation class
won't read/write to the data structures when an update of that data is
going on.


import CORBA, SimServer, SimServer__POA

from threading import *
import time

class SimServer:
    def __init__(self, sim, user, lock):
        self._thread =3D Thread(target=3Dself.run, name=3D"Orbit")
        argv =3D []
	argv.append('ORBIIOPIPv4=3D1')
	self.orb =3D CORBA.ORB_init(argv)
	self.poa =3D self.orb.resolve_initial_references("RootPOA")
	ref =3D SimServer_Sim_Impl(sim, user, lock)._this()
	open("server.ior", "w").write(self.orb.object_to_string(ref))
        self.poa.the_POAManager.activate()
#        self._thread.setDaemon(1)
        print "pre thread start"
        self._thread.start()
        print "post thread start"
    def run(self):
        print "orb run"
        print enumerate()
#       time.sleep(500)
        self.orb.run()
        print "orb end"
