24-25: LGTM! Consider adjusting parameter order in the error message.The new
MQBrokerErrorvariant is a good addition, providing more detailed information about client exceptions. The error message is clear and includes all the necessary information.Consider adjusting the order of parameters in the error message to match the declaration order for better readability:
#[error("Client exception occurred: CODE:{0}, Message:{1}, broker address:{2}")] MQBrokerError(i32, String, String),This change would make the code more intuitive and easier to maintain.
rocketmq-remoting/src/protocol/body/broker_body/broker_member_group.rs (3)
25-27: Approved: Type changes improve structure clarity and safety.The modifications to the
BrokerMemberGroupstruct fields enhance type safety by makingclusterandbroker_namenon-optional, and improve thebroker_addrsfield by usingu64for broker IDs. These changes align well with the intended use of the struct.Consider adding documentation comments to explain the significance of these fields and any constraints (e.g., non-empty strings for
clusterandbroker_name, valid ranges for broker IDs).
31-31: Approved: Constructor signature aligns with struct changes.The
newmethod signature has been updated to match the changes in theBrokerMemberGroupstruct fields. This ensures consistency and makes the API more straightforward to use.Consider adding an additional constructor method (e.g.,
with_addrs) that allows initializing the struct with pre-populated broker addresses. This would provide flexibility for cases where the addresses are known at creation time:impl BrokerMemberGroup { pub fn with_addrs(cluster: String, broker_name: String, broker_addrs: HashMap<u64, String>) -> Self { Self { cluster, broker_name, broker_addrs, } } }
35-35: Approved: Consistent initialization of broker_addrs.The initialization of
broker_addrswith an emptyHashMapis consistent with the updated constructor signature and ensures that the field is always properly initialized.For a minor optimization, consider using
HashMap::new()instead ofHashMap::new():broker_addrs: HashMap::new(),This change doesn't affect functionality but is slightly more idiomatic in Rust.
rocketmq-remoting/src/protocol/body/request/lock_batch_request_body.rs (1)
24-24: LGTM. Consider optimizingOption<String>fields if appropriate.The addition of the
Clonetrait is a good improvement, allowing for more flexible use of theLockBatchRequestBodystruct. This change is safe and doesn't introduce any issues.Consider reviewing the use of
Option<String>forconsumer_groupandclient_id. If these fields are always expected to have a value, changing them toStringcould simplify the code and improve performance slightly. For example:pub struct LockBatchRequestBody { pub consumer_group: String, pub client_id: String, pub only_this_broker: bool, pub mq_set: HashSet<MessageQueue>, }This change would require updating the
Displayimplementation and any code that constructs or uses this struct. Please verify if this optimization aligns with the intended use of these fields throughout the codebase.rocketmq-common/src/common/broker/broker_config.rs (3)
172-172: Add documentation for the new fieldlock_in_strict_mode.The purpose and impact of the new
lock_in_strict_modefield are not clear from its name alone. Please add a doc comment explaining:
- What "strict mode" means in this context.
- How this field affects the broker's behavior.
- Any potential performance implications or use cases for enabling/disabling this mode.
This documentation will help other developers understand when and how to use this new configuration option.
249-249: LGTM. Consider grouping related configuration options.The addition of
lock_in_strict_modewith a default value offalseis appropriate. It maintains backward compatibility and allows users to opt-in to the new behavior.As a minor improvement, consider grouping this new option with other related locking or concurrency settings in the struct initialization, if any exist. This can enhance readability and make it easier for developers to locate and configure related options.

260-479: Updateget_propertiesmethod to include the newlock_in_strict_modefield.The
get_propertiesmethod, which appears to serialize the broker configuration, doesn't include the newly addedlock_in_strict_modefield. To ensure consistency and completeness of the configuration representation, please update this method to include the new field.Add the following line to the
get_propertiesmethod:properties.insert( "lockInStrictMode".to_string(), self.lock_in_strict_mode.to_string(), );This will ensure that the new configuration option is properly serialized and available when the properties are used elsewhere in the system.

70-74: Avoid magic numbers by defining constants for capacity initialization.Using hard-coded values like
32and8forHashMapcapacities can reduce code clarity. Defining these numbers as constants or configuring them makes the code more maintainable.For example:
const MQ_LOCK_MAP_INITIAL_CAPACITY: usize = 32; const ADDR_MAP_INITIAL_CAPACITY: usize = 8; let mut mq_lock_map = HashMap::with_capacity(MQ_LOCK_MAP_INITIAL_CAPACITY); let mut addr_map = HashMap::with_capacity(ADDR_MAP_INITIAL_CAPACITY);rocketmq-broker/src/out_api/broker_outer_api.rs (2)
359-360: Handleinvoke_asyncerrors more specificallyCurrently, all errors from
invoke_asyncare wrapped inBrokerClientError(e), which might obscure the underlying issue. Consider matching on the error type to provide more specific error handling and better context for troubleshooting.For example:
- Err(e) => Err(BrokerClientError(e)), + Err(e) => match e { + // Handle timeout errors + RemotingError::RequestTimeout => Err(BrokerError::TimeoutError(e)), + // Handle connection errors + RemotingError::ConnectionRefused => Err(BrokerError::ConnectionError(e)), + // Handle other errors + _ => Err(BrokerClientError(e)), + }By matching on specific error variants, you can provide more meaningful error messages and handle different error scenarios appropriately.
330-361: Add unit tests forlock_batch_mq_asyncTo ensure the reliability of the new
lock_batch_mq_asyncmethod, it is important to have unit tests that cover various scenarios, such as successful responses, error responses, and exceptions.Would you like assistance in creating unit tests for this method? Proper testing will help catch potential issues early and ensure that the method behaves as expected under different conditions.

💡 Codebase verification
🛠️ Refactor suggestion
Inconsistency Found in Error Message Formatting
The reordering of parameters in the MQBrokerError variant (broker address moved to {2}) introduces inconsistency with the OffsetNotFoundError variant, which still uses {1} for the broker address. This inconsistency is present in multiple areas of the codebase, potentially leading to confusion and errors in error handling.
To address this issue:
-
Standardize Parameter Ordering:
- Update the
OffsetNotFoundErrorvariant to match the parameter order ofMQBrokerError:#[error("Client exception occurred: CODE:{0}, broker address:{2}, Message:{1}")] OffsetNotFoundError(i32, String, String),
- Update the

🛠️ Refactor suggestion
Consider returning None when no broker addresses are found.
The current implementation always returns Some(group_member), even if no broker addresses were added. This might lead to confusion for the caller, as they receive a BrokerMemberGroup with an empty broker_addrs map.
Consider modifying the function to return None when no broker addresses are found:
pub(crate) fn get_broker_member_group(
&mut self,
cluster_name: &str,
broker_name: &str,
) -> Option<BrokerMemberGroup> {
let mut group_member =
BrokerMemberGroup::new(cluster_name.to_string(), broker_name.to_string());
if let Some(broker_data) = self.broker_addr_table.get(broker_name) {
let map = broker_data.broker_addrs().clone();
for (key, value) in map {
group_member.broker_addrs.insert(key as u64, value);
}
- Some(group_member)
+ if group_member.broker_addrs.is_empty() {
+ None
+ } else {
+ Some(group_member)
+ }
+ } else {
+ None
}
- Some(group_member)
}This change ensures that the function only returns Some(group_member) when broker addresses are actually found, providing more meaningful information to the caller.

🛠️ Refactor suggestion
Enhance error handling for asynchronous operations.
Currently, when lock_batch_mq_async fails, the error is logged but not handled further. Consider implementing retries or alternative error handling strategies to improve reliability.
You might implement an exponential backoff retry mechanism or aggregate failed broker addresses for further analysis.

Confirm thread safety without Arc<MessageQueue>
By removing Arc<MessageQueue> and using MessageQueue directly, confirm that thread safety is maintained, especially if MessageQueue contains internal mutability or is shared across threads. The use of RwLock helps with synchronization, but it's important to ensure no data races occur.

🛠️ Refactor suggestion
Replace repetitive test setup code with a helper function
The test cases repeatedly create a default MessageQueue and insert it into a HashSet. Consider refactoring this common setup into a helper function to adhere to the DRY (Don't Repeat Yourself) principle, improving maintainability and readability.
Implement a helper function for creating the test HashSet<MessageQueue>:
fn create_test_mq_set() -> HashSet<MessageQueue> {
let mq = MessageQueue::default();
let mut set = HashSet::new();
set.insert(mq);
set
}Then update the tests:
#[test]
fn lock_all_expired_returns_false_when_active_locks_exist() {
let manager = RebalanceLockManager::default();
- let mq = MessageQueue::default();
- let mut set = HashSet::new();
- set.insert(mq.clone());
+ let set = create_test_mq_set();
manager.try_lock_batch("test_group", &set, "client_1");
assert!(!manager.is_lock_all_expired("test_group"));
}Repeat for other test cases.

🛠️ Refactor suggestion
Avoid unnecessary cloning of MessageQueue when inserting into HashSet
Cloning MessageQueue instances with mq.clone() may introduce performance overhead, especially if MessageQueue is a complex struct. Consider iterating over references and adjusting ownership to minimize or eliminate the need for cloning.
Apply this diff to reduce cloning:
for mq in mqs.iter() {
if self.is_locked(group, mq, client_id) {
- lock_mqs.insert(mq.clone());
+ lock_mqs.insert((*mq).clone());
} else {
- not_locked_mqs.insert(mq.clone());
+ not_locked_mqs.insert((*mq).clone());
}

🛠️ Refactor suggestion
Improve logging and error messages for better debugging
When the response code is not ResponseCode::Success, the error returned lacks detailed context. Enhancing the error message with additional information can aid in debugging and provide clearer insights into failures.
Consider including the address and any relevant request details in the error:
Err(BrokerError::MQBrokerError(
response.code(),
response.remark().cloned().unwrap_or_else(|| "Unknown error".to_string()),
"".to_string(),
))
+ .context(format!(
+ "Failed to lock batch MQ at addr: {}, request: {:?}",
+ addr, request
+ ))This addition provides more context about where and why the failure occurred.

Avoid using unwrap() to handle potential None values
Using unwrap() on response.get_body() can lead to a panic if the body is None. Instead, handle the None case gracefully to prevent unexpected crashes.
Apply this diff to handle the Option safely and propagate errors appropriately:
- let lock_batch_response_body =
- LockBatchResponseBody::decode(response.get_body().unwrap()).unwrap();
+ let body = response.get_body().ok_or_else(|| {
+ BrokerError::MQBrokerError(
+ response.code(),
+ "Response body is empty".to_string(),
+ "".to_string(),
+ )
+ })?;
+ let lock_batch_response_body = LockBatchResponseBody::decode(body)?;This modification ensures that if the response body is None, an appropriate error is returned. Additionally, using the ? operator on the decode method propagates any decoding errors without panicking.
