1040-1040: Ensure correct error handling before unlocking
Callingunlock_with_keyfollowed by a direct return may skip potential error handling or cleanup. Make sure this early return path is valid and does not introduce partial updates or side effects that could lead to inconsistencies.Consider documenting the rationale behind this design or wrapping the unlock call in higher-level error handling to ensure consistent cleanup.
1058-1080: Collapse nested if statements to address Clippy warning
Clippy suggests merging the nested if conditions into a single if statement, which can improve readability and maintainability. Below is a possible fix:} else if let Some(status) = result_inner.status() { - if matches!( - status, - GetMessageStatus::NoMatchedMessage - | GetMessageStatus::OffsetFoundNull - | GetMessageStatus::MessageWasRemoving - | GetMessageStatus::NoMatchedLogicQueue - ) { - if result_inner.next_begin_offset() > -1 { + if matches!( + status, + GetMessageStatus::NoMatchedMessage + | GetMessageStatus::OffsetFoundNull + | GetMessageStatus::MessageWasRemoving + | GetMessageStatus::NoMatchedLogicQueue + ) && result_inner.next_begin_offset() > -1 + { if is_order { self.broker_runtime_inner .consumer_offset_manager() .commit_offset( channel.remote_address().to_string().into(), &request_header.consumer_group, topic, queue_id, result_inner.next_begin_offset(), ); } else { unimplemented!("PopMessageProcessor pop_msg_from_queue") } } } }🧰 Tools

994-994: Questionable immediate unlock of the queue lock
Immediately unlocking the queue lock after checkingtry_lock_with_keymay introduce a time window for concurrency issues or race conditions between reading and updating the queue state. Please verify that the subsequent operations do not rely on the queue being locked.If you want to confirm the correctness, you can run this shell script to search for additional references to this lock key, to see if the queue state might be mutated between the lock/unlock calls:
