Adjustment of acknowledgement deadline for pubsub functions

See original GitHub issue

When deploying a function the ack deadline is set to 10 mins (and cannot be changed in GCP) - is there anyway to change this and could it be added in to the .topic() function builder?

As a side note I also tried to change it with glcoud and got the following error:

> gcloud pubsub subscriptions update projects/<projectId>/subscriptions/<subscriptionId> --ack-deadline=180

ERROR: (gcloud.pubsub.subscriptions.update) INVALID_ARGUMENT: The supplied AppEngine URL project does not match the subscription's parent project (url="https://<some-random-uuid>.appspot.com/_ah/push-handlers/pubsub/projects/<projectId>/topics/<topicId>?pubsub_trigger=true", project_id="<projectId>").

Sorry this bug has taken so long to get to. We are not going to add a timeout option to the topic function; you shouldn’t have to manually configure two different timeouts (function and subscription). We’re also going to leave the deadline at 600s.

Instead, we’re working on the Pub/Sub infrastructure so that it notices hangups as a NACK. This means that any function which times out will be killed by our scheduler and cause a NACK on the pub/sub topic which will schedule the re-delivery immediately. This fix is currently rolling out to production.

https://issuetracker.google.com/issues/152149355 I’m getting “Access denied” for this link now…

Anyone any ideas why the ack deadline is set to 10 mins and not something just above the timeout of the function?
