STINNER Victor <[email protected]> added the comment:
test_shared_memory_cleaned_after_process_termination() uses time as a weak
synchronization primitive:
# killing abruptly processes holding reference to a shared memory
# segment should not leak the given memory segment.
p.terminate()
p.wait()
time.sleep(1.0) # wait for the OS to collect the segment
with self.assertRaises(FileNotFoundError):
smm = shared_memory.SharedMemory(name, create=False)
Would it be possible to use a more reliable synchronization? Such test usually
fail randomly.
