2.0.0 / 2020-08-06

This is a major update that removes the "low-level" client interface code, and instead adds the new google-cloud-pubsub-v1 gem as a dependency. The new dependency is a rewritten low-level client, produced by a next- generation client code generator, with improved performance and stability.

This change should have no effect on the high-level interface that most users will use. The one exception is that the (mostly undocumented) client_config argument, for adjusting low-level parameters such as RPC retry settings on client objects, has been removed. If you need to adjust these parameters, use the configuration interface in google-cloud-pubsub-v1.

Substantial changes have been made in the low-level interfaces, however. If you are using the low-level classes under the Google::Cloud::PubSub::V1 module, please review the docs for the new google-cloud-pubsub-v1 gem. In particular:

• Some classes have been renamed, notably the client classes themselves.
• The client constructor takes a configuration block instead of configuration keyword arguments.
• All RPC method arguments are now keyword arguments.

  • Note: At the time of this release, ordering keys are not yet publicly enabled and requires special project enablements.

Bug Fixes

• Fix Subscriber state after releasing messages
  • Correctly reset the Subscriber state when releasing messages after the callback either raises an error, or the callback fails to call acknowledge or modify_ack_deadline on the message. If a Subscriber fills it's inventory, and stops pulling additional messages before all the callbacks are completed (moves to a paused state) then the Subscriber could become stuck in a paused state.
  • A paused Subscriber will now check whether to unpause after the callback is completed, instead of when acknowledge or modify_ack_deadline is called on the message.

  • Changes to avoid potential race conditions in updates.
• Add reference?/resource? helper methods:
  • Topic#reference?
  • Topic#resource?
