New submission from Marko <ivanovic.ma...@yandex.com>:
When child process dies unexpectedly Queue.get waits indefinitely.
Here is example:
import os
import signal
import multiprocessing
def child_func(qa, qb):
input = qa.get()
print('Child received: ', input)
os.kill(os.getpid(), signal.SIGTERM)
qb.put('B')
exit(0)
qa = multiprocessing.Queue()
qb = multiprocessing.Queue()
process = multiprocessing.Process(target=child_func, args=(qa, qb))
process.start()
qa.put('A')
try:
input = qb.get()
print('Parent received: ', input)
except Exception as ex:
print(ex)
process.join()
exit(0)
