Hi Gabriel,
There's two problems from what I can see.
1) You have a method run in a thread
def __myLoop(self):
while True:
self.transport.write("Thread")
time.sleep(1)
but since it's being run in a thread, you need to schedule the call
into the reactor like so:
def __myLoop(self):
while True:
reactor.callFromThread(self.transport.write, "Thread")
time.sleep(1)
2) Your loop in that thread will run forever no matter what. It isn't
a daemon thread so there needs to be some sort of stopping criterion
(there's no way to kill Python threads externally):
def __myLoop(self):
while self.factory.running:
reactor.callFromThread(self.transport.write, "Thread")
time.sleep(1)
By setting an attribute on the factory in the __init__ called
'running' to True, then in the signal handler code we can set it to
False, providing a quick and dirty way to bail out of that thread.
I made the modifications and sending a cntrl-C made the program exit just fine.
Cheers,
Reza
