stoppable child thread

[james_w77]

I am trying to use Peter's StoppableThread(threading.Thread).

What I want to do is to start 5 child threads, then do something, then
when got ^C keyboard exception, stop the child thread.

For some reason (apparently strange for me ), the child threads can
NOT be stopped.

See the enclosed code for more info,

Thanks and have a nice Xmas.

============

#!/usr/bin/env python

import threading, thread
from time import sleep, ctime


class StoppableThread(threading.Thread):
def __init__(self):
threading.Thread.__init__(self)
self._running = True


def stop(self):
self._running = False


def run(self):
while self._running:
# do stuff here that loops periodically to allow
# the flag to be checked
print 'start loop at:', ctime()
sleep(4)



def main():
threads = []
try:
for i in range(5):
t = StoppableThread()
t.start()
sleep(0.001)
threads.append(t)


except KeyboardInterrupt:
for t in threads:
t.stop()
t.join()
del threads[:]
print 'child thread exiting...'+'/n/n'



if __name__ == '__main__':
main()

(e-mail address removed) ha escrito:

def main():
threads = []
try:
for i in range(5):
t = StoppableThread()
t.start()
sleep(0.001)
threads.append(t)


except KeyboardInterrupt:
for t in threads:
t.stop()
t.join()
del threads[:]
print 'child thread exiting...'+'/n/n'

Put a print statement just at the end of main() and see what happens.
You said:

You've created the threads, you've handled ^C, what's missing...?
