Windows Service in Python -

i following solution provided in following link create windows service python not hang in stopping state when try stop after days running.

timeout , windows services long running processes (python)

the problem facing after start service seems run once , service in windows service manager have tasks disabled can not stop or restart it. below code. have removed real tasks want perform , replace dummy service add 1 variable (x) every-time runs , write log file.

i appreciate tip in trying find mistake.

here configuration of logging module. save in text file , save teste_logging.conf

i have found reason why services task disabled. forgot implement svcstop function.

def svcstop(self):     self.reportservicestatus(win32service.service_stop_pending)     win32event.setevent(self.hwaitstop)     

nevertheless still runing once.
