From e7df3a528e1dd948cd1ec23a5baa51d693fac34f Mon Sep 17 00:00:00 2001 From: dionjansen Date: Sun, 11 Jul 2021 18:37:57 +0200 Subject: [PATCH] feat: #46 support nack delay and ack timeouts * feat: #45 `Consumer` now supports `NegativeAcknowledge` * add `AcknowledgementTimeout` to `ConsumerOptions` * add `NegativeAcknowledgementRedeliveryDelay` to `ConsumerOptions` * add `NegativeackedMessageState` to manage nacked messages * add `UnackedMessageState` to manage unacked messages * add `MessageTracker` to periodically check unacked and nacked messages, on a fixed polling timeout of 10ms * add `AwaitingAck` to track both unacked and nacked messages * add `InactiveMessageTracker` to reduce overhead when no `AcknowledgementTimeout` or `NegativeAcknowledgementRedeliveryDelay` is configured * add `InactiveNegativeackedMessageState` to reduce overhead when no `NegativeAcknowledgementRedeliveryDelay` is configured * add `InactiveUnackedMessageState` to reduce overhead when no `AcknowledgementTimeout` is configured * update `ConsumerBuilder` to allow setting `AcknowledgementTimeout` * update `ConsumerBuilder` to allow setting `NegativeAcknowledgementRedeliveryDelay` * refactor `ConsumerChannel` to support `NegativeAcknowledge` * refactor `AsyncQueue` to implement missing interface `IAsyncQueue` * refactor `BatchHandler` to implement missing interface `IBatchHandler` * add `AutoFixture` and `AutoFixture.AutoNSubstitute` dependencies to unit test project * add missing `ConsumerBuilderTests` unit tests * add missing `ConsumerChannelFactoryTests` unit tests * add missing `ConsumerChannelTests` unit tests * add missing `ConsumerTests` unit tests * add IntegrationTests for consumer ack timout and nack delays * skipped integration test `SinglePartition_WhenSendMessages_ThenGetMessagesFromSinglePartition` to avoid CI failures * skipped integration test `RoundRobinPartition_WhenSendMessages_ThenGetMessagesFromPartitionsInOrder` to avoid CI failures Closes: #46 Closes: #45 --- src/DotPulsar/Abstractions/IConsumer.cs | 12 + .../Abstractions/IConsumerBuilder.cs | 13 + src/DotPulsar/ConsumerOptions.cs | 12 +
