Description
Type: Bug
Behaviour
Expected vs. Actual
Launching a debugger instance when multiprocessing is involved causes the debugger to exit without any error.
When process.join() is added to the code it works fine but not without it.
Steps to reproduce:
Add a breakpoint at time.sleep(5) line and wait few seconds
import time
from multiprocessing import Process
class MyClass:
def run(self):
process = Process(target=self.launch)
process.start()
# process.join()
def launch(self):
print("Started")
time.sleep(5) # Try to add breakpoint at this line
print("Finished")
if __name__ == "__main__":
obj = MyClass()
obj.run()Diagnostic data
