For very long-running tasks, we can reset the ack deadline every once in a while by calling modify_ack_deadline on the Subscriber API Client in separate processes.

Does anyone know what happened to the CircleCI check? No sign of it since I submitted.

Does this really have to be a defaultdict? Since it's iterating over it's own elements sequentially, wouldn't it always succeed on popping the processes?

How about renaming d to processes?

Also, received_message can also be renamed to message since there is no clashing name to disambiguate from (to reduce verbosity).

received_message has a message property. But I like the idea of reducing verbosity.

Can you be more specific on the "bounded amount of time"? How long will it wait for messages to arrive? Is there a default value and/or can we change that?

All the documentation I could find says the same thing word for word. If set to True, we can specify a timeout time though. I'm also asking your question here.

Can we make this smaller, to let's say 30? That way it will be obvious that without resetting the deadline some messages won't be processed fully since the max running time is 60.

Please add a more detailed explanation on how this affects the deadline, i.e. that it resets the deadline timer and change it to ACK_DEADLINE every 10 seconds.

Should we test these two functions independently?

Maybe reword "Builds a pull request with a specific number of messages" to "The subscriber pulls for a specific number of messages"? A pull request makes me think of github :)

Can you explain a little further how the return_immediately and the timeout relate to each other and how each affects the behavior? I.e. what happens if I don't specify any of them and what the default values are?

Both are optional. I think the default values are based on the server, but may not be fixed.

I just tested without specifying either of them, subscriber waits without timing out. I'm going to remove such specifications for the code sample because we should stick to the most simple case.

Nit: can omit the s after the numbers since ack_deadline_seconds is already being explicit with it.

Otherwise -> If the process finished

When reading from top to bottom, it's hard to remember where the else is. It's easier to read the "else" condition explicitly.

Since these are synchronous and shouldn't step over each other, can we use the same subscription for both synchronous tests?

They sometimes did step on each other because the tests are run in parallel.

For consistency with the synchronous_pull_with_lease_management, can we rename this function to synchronous_pull?
