I'm creating an UDP SocketServer, and I would like to shutdown if I'm receiving a close message from the client side than I would like to close the UDP connection.
As I received the message the Begin will be displayed, but the Finished is not displayed. How can I exit from this thread?
class MyUDPHandler( SocketServer.BaseRequestHandler ):
def handle( self ):
data = self.request[0].strip()
dic = self.string_XML_to_dic( data )
if( dic['Cmd'] == str(UDPConst().SHUT_DOWN )):
print('Begin')
self.server.shutdown()
print("Finished")
if __name__ == "__main__":
HOST, PORT = "", prop['udpport']
server = SocketServer.UDPServer( ( HOST, PORT ), MyUDPHandler )
server.serve_forever()
As you are not running the server in it's own thread (you need to inherit ThreadingMixIn for that), you can not use shutdown as it will cause a deadlock. From the function document comment in the source:
Blocks until the loop has finished. This must be called while serve_forever() is running in another thread, or it will deadlock.
