Hi,
Thanks for the reply.
I actually came across Process documentation for twisted; but in my case my
the script which calls the twisted client is not implemented in Twisted
It is just a controller program which instantiates a central repository and
spawns off 2 threads and then the threads update to that repository
periodically (so I did not feel the need to run a reactor loop as in Twisted
).
Is there any way to call a Twisted client in a Process or a thread without
using the reactor?
To explain better:
master.py spawns 2 threads to update a central repository.
build_worker_t : launches a Twisted client to connect to a Twisted server
running on a build machine
test_worker_t : launches a Twisted client to connect to a Twisted server
running on a Test Machine
master.py:
___________________________________________________________________
// make a central repository for the threads to update
class Globals:
repo = []
lock = threading.Lock()
def main():
build_worker_t = threading.Thread( target=dispatch_build_worker)
build_worker_t.start()
test_worker_t = threading.Thread( target=dispatch_test_worker)
test_worker_t.start()
build_worker_t.join()
test_worker_t.join()
def dispatch_build_worker():
# build_worker.main is a twisted client
foo = Process(target=build_worker.main, args=(build_q,uid,))
foo.start()
foo.join() //wait for the process(ie. client-server communication to
finish)
//get status from build_q and update repo
def dispatch_test_worker():

Launching the client in this manner, is not showing reliable results.
You didn't give a long enough example to be certain, but that looks like multiprocessing.Process syntax. The multiprocessing module does not work reliably with Twisted. Neither does the subprocess module.
You should use the equivalent Twisted process functionality, shown at http://twistedmatrix.com/projects/core/documentation/howto/process.html
There's also https://launchpad.net/ampoule, but for the small example you show, the basic Twisted process stuff should be fine.
