In my Python program, I need to detect and gracefully handle signal.SIGTERM
signal.SIGTERM
I use the following two small Python programs to send and handle signal.SIGTERM:
signal.SIGTERM
Receiver and handler:
Receiver and handler:
import signal, time, os

def handle_signal(signum, frame):
global running
print ("Received signal", signum)
running = False

# Write the PID to a file

running = True
while running:

import signal, time, os

def handle_signal(signum, frame):
global running
print ("Received signal", signum)
running = False

# Write the PID to a file

running = True
while running:

Sender:
Sender:
import os, signal, time

# Read PID from file

# Send SIGUSR1 signal

import os, signal, time

# Read PID from file

# Send SIGUSR1 signal

As soon as I send signal.SIGTERM to the receiver, it gets terminated, but handle_signal is never called.
signal.SIGTERM
handle_signal
Why? How can I make this setup work under Windows 11 or Windows platform?
