japronto catch the SIGINT, how can I register my own signal handler ? #54

Open jiamo opened 7 years ago

I create an process before create app. When I kil -2 pid. The program got Termination request receive and hangup.

In my create process I also register the handle to SIGINT. When I using ctrl+c the program can exit.

By the way , I can catch SIGUSR1 to handle this problem . After join my custom process main process, I must using : 

def handle_signal(signal, frame):
    print("handle signal_int start\n")
    custom_process.kill()
    custom_porcess.join()
    print("handle end")
    sys.exit()

So In this situation How can I avoid using sys.exit()? Can japronto's workprocess be kill by main process out of the application?

Currently that's not supported, the best you can do is find relevant piece of code of Application and change it yourself or use monkey patching.

As stated earlier I am working now on inner guts of japronto and won't start adding more user facing APIs until I'm sure that inner design is OK. I will keep this open to add desired funcionality when I am ready.
