Hi Gabriel,
Hello Reza,
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)
Yes, I forgot to do that in the example, silly me, I do do that in my
real code though.
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.
Ahh, ok, I though Twisted would stop them somehow, That must be it then
one of my threads must not exit and thus runs forever and Twisted waits
on it.
I made the modifications and sending a cntrl-C made the program exit just fine.
Cheers,
Reza
Thank you!

Hello everyone,
I was able to write a small example that reproduces my problem, when I
redefine signal and I have threads and I try to stop the reactor, it hangs.
I wasn't sure if it was loopingCall or callLater or threads at first, but
from my tests it's the threads that cause the problem. I attached the
example, it's a modified version of the Twisted echo server/client example.
Run the server, run the client, press Ctrl + C in the client's terminal (or
Ctrl + break on windows) and it doesn't quit. I still have to test if it's
caused by the signal redefinition at all or not.
Thank you,
Gabriel Rossetti
