Conversation
WalkthroughWalkthroughThe changes introduce a new logging framework using Logback, enhance message handling efficiency by streamlining logging and exception handling, and improve test robustness for the Pub/Sub functionality. The updates focus on better logging, clearer code, and robust test coverage to ensure that the unarchive mechanism in the Pub/Sub system works correctly. Changes

resources/logback.xml (1)
1-17: Review oflogback.xmlConfigurationThe configuration seems correct and well-structured. It defines a console appender with a specific pattern layout and sets the logging level for the
com.moclojerpackage to debug while the root level is set to error. This setup should work well for development purposes but consider adjusting the root logging level for production if needed to avoid verbose logging.deps.edn (1)
5-5: Dependency Addition:ch.qos.logback/logback-classicThe addition of
ch.qos.logback/logback-classicversion "1.5.6" is appropriate for integrating Logback as the logging framework. Ensure that this version is compatible with other dependencies and the Clojure version used in the project.test/com/moclojer/rq/pubsub_test.clj (3)
26-32: Updated Unarchive Function Signature in TestsThe change in the
unarchive-channel!function signature to accept a function that resets the state with the message is a good practice for handling dynamic data in tests. Ensure that the new function signature is correctly implemented across all usages.
40-42: Subscription Function Signature ChangeThe modification to
subscribe!to accept a list of channel-handler maps improves flexibility in handling multiple subscriptions. This is a significant improvement for testing scenarios involving multiple channels.
48-54: Increase in Workers for Multi Pub/Sub TestIncreasing the number of workers from 1 to 5 in the
build-workersfunction is a sensible change to test the system under more realistic conditions. This should help in identifying concurrency issues if any.src/com/moclojer/rq/queue.clj (1)
54-59: Reorganized Logging inpop!FunctionMoving the logging statement inside the conditional where the message is present is an efficient change. This prevents unnecessary logging calls when there is no message, thus reducing the noise in log files and potentially improving performance.
src/com/moclojer/rq/pubsub.clj (3)
82-84: Approve change in logging level for unarchiving.Changing the logging level from debug to info in
unarquive-channel!helps increase visibility of the unarchiving process in production environments, which is beneficial for monitoring and troubleshooting.
116-116: Approve syntactic improvement inpack-workers-channels.The change to simplify the lambda function improves readability and maintains functionality.
54-56: Discuss removal of exception handling in message processing.Removing the exception handling in
consume-from-channel!simplifies the code but could lead to unhandled exceptions if there are issues with message formatting or the handler function. This change assumes that there's a higher-level exception management strategy.
