I am writing a program by a framework using pygtk. The main program doing the following things:
- Create a watchdog thread to monitor some resource
- Create a client to receive data from socket
- call
gobject.Mainloop()
but it seems after my program enter the Mainloop, the watchdog thread also won t run.
My workaround is to use gobject.timeout_add to run the monitor thing.
But why does creating another thread not work?
Here is my code:
import gobject
import time
from threading import Thread
class MonitorThread(Thread):
def __init__(self):
Thread.__init__(self)
def run(self):
print "Watchdog running..."
time.sleep(10)
def main():
mainloop = gobject.MainLoop(is_running=True)
def quit():
mainloop.quit()
def sigterm_cb():
gobject.idle_add(quit)
t = MonitorThread()
t.start()
print "Enter mainloop..."
while mainloop.is_running():
try:
mainloop.run()
except KeyboardInterrupt:
quit()
if __name__ == __main__ :
main()
The program output only "Watchdog running...Enter mainloop..", then nothing. Seems thread never run after entering mainloop.
