1069-1583: Improve test coverage for core message processing logic.While there is good test coverage for utility functions (ID generation, locking), the core message processing logic lacks tests. Consider adding tests for:
- Message popping logic and stopping conditions
- Checkpoint handling and verification
- Message notification system
- Error scenarios and edge cases
Would you like me to help generate comprehensive test cases for the core message processing logic?
Critical: Confirmed unimplemented notification function
The
notify_message_arrivingfunction inpop_message_processor.rsis indeed unimplemented but is called from multiple locations. It should be implemented by delegating to the existing notification logic inPopLongPollingService.

Critical: Implement
append_check_pointin PopMessageProcessorThe
append_check_pointfunction inpop_message_processor.rsis indeed unimplemented, which affects core message processing functionality. However, note that checkpoint functionality is properly implemented in other components likechange_invisible_time_processor.rs, so this is a localized issue specific to the PopMessageProcessor component.

💡 Codebase verification
Critical: Implement is_pop_should_stop based on Java reference implementation
The function should check if pop message threshold is enabled and if the number of in-flight messages exceeds the threshold. Implementation guidance:
- Access broker configuration to check if pop message threshold is enabled
- Use in-flight message counter to get the number of in-flight messages for the given topic, group, and queue
- Return true if threshold is enabled and in-flight messages exceed the configured threshold
Example from Java implementation:
return brokerController.getBrokerConfig().isEnablePopMessageThreshold() &&
brokerController.getPopInflightMessageCounter().getGroupPopInFlightMessageNum(topic, group, queueId) >
brokerController.getBrokerConfig().getPopInflightMessageThreshold();🔗 Analysis chain
Critical: Implement the is_pop_should_stop function.
The is_pop_should_stop function is marked as unimplemented, which is a critical issue as it's used to control the message popping flow. This function needs to be implemented to properly handle the stopping condition.
Let's verify if there are any existing implementations or references to guide the implementation:
