[issue37334] Add a cancel method to asyncio Queues

[Martin Teichmann]

Martin Teichmann <martin.teichmann at gmail.com> added the comment:

Yes, in the one-producer-many-consumers situation on can indeed to the trick with the None. But this is just a clumsy hack, cancelling the tasks is IMHO more in line with asyncio.

In the many-producers-one-consumer scenario this does not work. The one dead consumer cannot feed back to the producers. Sure, there are still many hacks imaginable, but a closing or cancelling the queue is a very clear way of doing things.

As for the naming: I personally don't care, close() or cancel() are both fine with me.
