Any way to kill or stop stack.start()

[carlosfelipe29]

hi @tgalal , @aesedepece, @pungoyal .

Is there any way to stop or kill the stack.start() procedure when I received a request, without exit the program?? It means, to stop or to disconnect meanwhile I do another process and after that, it connects and Answer.

def start(self): self.stack.broadcastEvent(YowLayerEvent(YowNetworkLayer.EVENT_STATE_CONNECT)) try: self.stack.loop() except AuthError as e: print("Authentication Error: %s" % e.message)

I run the script on a threading process to have simultaneously different task. stack=YowsupReceiveStack(credential()) stack.start() But, After I receive the first request (word by whatsapp) it is able to get a response, after that it freezes, and the next requests does not seem to be read (message were lost), only when I do Ctrl+C and run again, it appears.

I try to use event_disconnect without succeded.

is there any way to stop this stack.start() , maybe call after, a function stack.stop() to do nothing and get disconnected for that iteration do what I want,and get alive when it runs the stack.start() again ?.

I appreciate your technical support .

Sorry for my poor english. This code receives time (in seconds) by param. The script runs during that time. When time is over, script stop.

import signal
if __name__ == "__main__":
    TIME_ = int(sys.argv[1]) #time in seconds

    ## handler for ALARM
    def handlerTimeOut(signum, frame):
        raise Exception()

    CREDENTIALS = ("NUM", "KEY")

    layers = (
        YOURSTACK,
        YowParallelLayer([YowAuthenticationProtocolLayer, YowNotificationsProtocolLayer, YowMessagesProtocolLayer,YowReceiptProtocolLayer, YowAckProtocolLayer]),
        YowAxolotlLayer,
        YowLoggerLayer,
        YowCoderLayer,
        YowCryptLayer,
        YowStanzaRegulator,
        YowNetworkLayer
    )

    stack = YowStack(layers)

    stack.setProp(YowAuthenticationProtocolLayer.PROP_PASSIVE, True)
    stack.setCredentials(CREDENTIALS)

    stack.setProp(YowNetworkLayer.PROP_ENDPOINT, YowConstants.ENDPOINTS[0])
    stack.setProp(YowCoderLayer.PROP_DOMAIN, YowConstants.DOMAIN)
    stack.setProp(YowCoderLayer.PROP_RESOURCE, env.CURRENT_ENV.getResource())

    stack.broadcastEvent(YowLayerEvent(YowNetworkLayer.EVENT_STATE_CONNECT))

    ## set alarm
    signal.signal(signal.SIGALRM, handlerTimeOut)
    signal.alarm(TIME_)

    try:
        stack.loop()
    except Exception, exc:
        print "Time over"

Hi, it really helps me.

It means, if I put a integer(num) on TIME_ = int( NUM), the stack.loop() will be open over a certain time, enough to read a messages on the server and then the connection is close. But it is possible to connect again. (like a switching).

thanks again

@bicapa Thanks a lot, It really works, It opens the stack.loop() some seconds (that I define). I tried to put on a thread, but it is not possible. I can not use SIGNAL module inside a Thread, it only works on a main thread.
Any ideas to stop the thread of read messages (maybe threadind.TIMER( ...) )

thanks.

hi carlosfelipe29, did you find any solution. I am in same problem and trying to find any solution. What I am doing I have multiple channels and I am switching that without exiting the program. So I creating the thread for each channel and when the task done I close that thread and create another thread with another channel. But I couldn't found any way to exit the stack.loop without sending ctrl+c but ctrl+c exit the complete program.

Thanks
