Details
- A couple of newly added tests were found to be flaky in `AuthorizerIntegrationTest.scala`. - `testShareGroupDescribeWithGroupDescribeAndTopicDescribeAcl` and `testShareGroupDescribeWithoutGroupDescribeAcl`. These tests pass locally, so could not replicate the failure. - But logs from develocity indicated that the test fails when the following condition happens : When the background error event arrives after the consumer had unsubscribed, then these events are processed in the `handleCompletedAcknowledgements` method and the exception from the event is thrown, preventing `close()` to complete. - We need to handle this race condition where we might get the background event after unsubscribe and before processing the callbacks. - PR fixes this by ignoring the exceptions in the background queue when the `handleCompletedAcknowledgements` method is called during `close()`. This ensures `close()` completes successfully. - Have added a unit test which mimics the race condition as well. Reviewers: Andrew Schofield <aschofield@confluent.io> |
