Xiang Zhang added the comment:
In Py3.6, it raises error:
>>> next((pool.imap(str, gen())))
Traceback (most recent call last):
File "/opt/lib/python3.7/multiprocessing/pool.py", line 684, in next
item = self._items.popleft()
IndexError: pop from an empty deque
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "/opt/lib/python3.7/multiprocessing/pool.py", line 690, in next
item = self._items.popleft()
IndexError: pop from an empty deque
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/opt/lib/python3.7/multiprocessing/pool.py", line 693, in next
raise StopIteration
StopIteration
But this doesn't looks good. I think it should raise TypeError. It can be fixed
in #28699.
