Terry J. Reedy <[email protected]> added the comment:
hang.py uses the default multiprocessing start method, which was then 'fork'.
It is now 'spawn' on macOS. And there have been many other changes. When I
run the following from IDLE, it finishes immediately.
import multiprocessing, sqlite3
def hang():
sqlite3.connect('/tmp/foo')
if __name__ == '__main__':
multiprocessing.Pool(2).apply_async(hang, []).get(999)
print('done')
Unless I am missing something, this should be closed as 'out of date'.
