Summary

Integration tests fail on RabbitMQ 4.3 because the broker rejects transient non-exclusive queues. This change makes the test queues durable or exclusive.

Problem

CI uses the floating rabbitmq:4-management image, which now resolves to 4.3.6. RabbitMQ 4.3 closes the connection with INTERNAL_ERROR - Feature transient_nonexcl_queues is deprecated. The integration tests declare queues with the default durable=False, exclusive=False, so they fail on every Python version. This blocks dependabot PRs #159–#162.

Solution

  • Declare the named test queues with durable=True. Each test deletes its queue in tearDown, so no queue stays on the broker.
  • Declare the server-named queue in UnnamedQueueDeclareTest with exclusive=True.

Verified locally against RabbitMQ 4.3.6: 39/39 integration tests pass, and the full suite (369 tests) passes.

Note: rabbitpy.Queue defaults to durable=False, so users who call Queue(channel, name) on RabbitMQ 4.3 will get the same error. This PR does not change library defaults.

Summary by CodeRabbit

  • Tests
    • Updated integration-test queue configurations to persist across relevant messaging scenarios.
    • Explicitly marked unnamed test queues as exclusive.
    • Test logic and assertions remain unchanged.

RabbitMQ 4.3 rejects transient non-exclusive queues with
INTERNAL_ERROR (Feature `transient_nonexcl_queues` is deprecated).
CI uses the floating rabbitmq:4-management image, so all
integration tests that declared default queues failed.

- Declare the named test queues as durable. Each test deletes its
  queue in tearDown, so no queue stays on the broker.
- Declare the server-named queue as exclusive.

📝 Walkthrough

Integration tests now declare named queues as durable across multiple scenarios. The unnamed queue test explicitly declares its queue as exclusive. Test logic and assertions remain unchanged.

Changes: Integration-test queue declarations

Layer / File(s) Summary
Queue declarations across integration scenarios
tests/test_integration.py
Named queues are declared durable across publish, consume, redelivery, multi-channel, nack, purge, large-message, and transaction tests. The unnamed queue test explicitly creates an exclusive queue.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~8 minutes

Change: Bug fix

Merge Risk: 🟡 Moderate · up to abdc6

Users creating named queues without specifying durability can still receive RabbitMQ 4.3 declaration errors; update the public default before merging.

A rabbit checks the queues at dawn
Durable flags are neatly drawn
One unnamed queue is exclusive
The test assertions stay as they were
I nibble hay beside the run
And hop away when checks are done

PR cycle summary:

  • CI: all 4 test jobs (3.11 to 3.14) pass at abdc68b.
  • CodeRabbit (1 Major comment): declined. The comment asks to change the public Queue default to durable=True. That is a breaking API change, out of scope for this test-only PR, and causes PRECONDITION_FAILED when code redeclares existing transient queues. Reply posted on the thread; thread resolved.
  • Needs human review: decide if a separate PR (major version) should change the default for RabbitMQ 4.3 users.
