From e1eaac30416ac6dc2e0ff88ba7de00a3a57aa6c4 Mon Sep 17 00:00:00 2001 From: Gabriele Santomaggio Date: Tue, 9 Jan 2024 22:40:37 +0100 Subject: [PATCH 1/5] Improve Reconnection * Part of https://github.com/rabbitmq/rabbitmq-stream-dotnet-client/issues/336 * Improve the disconnection message. It is possible to understand if it is a normal disconnection or an unexpected. * Remove the Active Items from the connection pool and use the Publishers and Consumers client list directly to check the pool size * Refactor the Factory Classes. Remove code duplication in case of metadata update and connection closed. See ReliableBase.OnEntityClosed * Handle streamNotAvailable error. In this case the client will try to reconnect the entity * Fix the events attach to the RawConsumer and RawProducer. The events are attached only if the ResponseCode is OK * Detach the events once the entity receives the disconnection or metadata update. In that case, the entity is closed * Introduce ReliableEntityStatus like a state machine to understand the status of Producer and Consumer classes * Add ResourceAvailableReconnectStrategy interface to Handle the retry in case testing in a stream exists. See ReliableBase CheckIfStreamIsAvailable * Change the MetadataHandler to Func to be like the other methods * Producer and Consumer classes fail fast during the first initialization. The user is aware of what is happening. The reconnect part occurs only after the first boot.
