Timeout test hangs IDLE

[Andreas Tawn]

I'm trying to integrate the timeout function from here
http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/473878 into a
long running automation script and the following code causes IDLE after
20 or 30 iterations in countTest.

This is in 2.5, XP and there's no traceback.

Could someone point me at the user error?

Thanks in advance.


def countTest():
    for i in xrange(10000000):
        print i
    return True

def timeout(func, args=(), kwargs={}, timeout_duration=1, default=None):
    import threading
    class InterruptableThread(threading.Thread):
        def __init__(self):
            threading.Thread.__init__(self)
            self.result = None

        def run(self):
            try:
                self.result = func(*args, **kwargs)
            except:
                self.result = default

    it = InterruptableThread()
    it.start()
    it.join(timeout_duration)
    if it.isAlive():
        return default
    else:
        return it.result

def runTest():
    timeout(countTest, timeout_duration=5)

if __name__ == "__main__":
    runTest()
