437-437: Use a meaningful and descriptive variable name.The variable
rest_numis introduced here to keep track of the remaining messages. Consider renaming it to a clearer name likeremaining_messagesorremaining_countfor better readability.
480-480: Avoid code duplication when forwardingrest_num.Similar to the logic on line 458, this line forwards
rest_numto another retry call. If both paths share logic, consider refactoring them into a helper function to reduce duplication.
521-521: Enhance comment clarity.The comment explains the retry logic if the result is not full. Expanding it with the exact condition or rationale helps future maintainers quickly understand how and why the additional fetch is triggered.
613-613: Add fallback logging for debugging.Defaulting to
PollingTimeoutis reasonable. Optionally add a debug or warning log indicating why this code path was triggered. This can help in diagnosing potential slow or hung polling operations.

439-439: Check correctness of retry logic assignment.
Here, rest_num is overwritten based on need_retry_v1. Verify that the two retry paths correctly aggregate the number of unprocessed messages, especially if partial consumption occurs before re-entering a retry path.
458-458: Confirm consistent usage of rest_num.
rest_num is forwarded as a parameter to pop_msg_from_topic_by_name. Ensure that the receiver method properly updates or uses rest_num to reflect the remaining messages accurately.
485-486: Clarify negative queue ID handling.
These lines treat negative queue_id as a signal to read from all queues. Document or validate that negative IDs are never used for valid queue indices, to prevent confusion or hidden bugs.
500-500: Pass rest_num carefully.
Once again, rest_num is passed to the next function. Confirm that the function properly updates this value to reflect newly discovered or consumed messages and that no partial read scenario is overlooked.
517-517: Validate concurrency impact on rest_num.
This line also forwards rest_num. Check if any concurrent modifications occur between multiple calls. You might need synchronization if rest_num updates in different threads or tasks.
573-573: Properly handle empty vs. found messages.
This check sets the status to Found if the resulting list is not empty. Confirm that code paths for partially retrieved messages (less than max requested) are correctly handled.
576-576: Check notification condition.
notify_message_arriving is triggered only when rest_num > 0. Make sure this covers all scenarios. If rest_num remains zero due to partial consumption or other logic, consider ensuring notifications are still sent only when actually needed.
