23-23: Consider updating error message to match the new variant nameThe variant has been renamed from
BrokerClientErrortoBrokerRemotingError, but the error message still uses "broker client error". For consistency, consider updating the error message to "broker remoting error: {0}".- #[error("broker client error: {0}")] + #[error("broker remoting error: {0}")] BrokerRemotingError(#[from] rocketmq_remoting::remoting_error::RemotingError),
38-67: LGTM! Consider adding tests for remaining variantsThe test coverage for error message formatting is good, with clear and meaningful test cases. However, consider adding tests for the
BrokerCommonErrorandClientErrorvariants to ensure complete coverage.Here's a suggested implementation for the additional tests:
#[test] fn broker_common_error_displays_correctly() { let error = BrokerError::BrokerCommonError(rocketmq_common::error::Error::IllegalArgument( "common error".to_string(), )); assert_eq!(format!("{}", error), "Common error: common error"); } #[test] fn client_error_displays_correctly() { let error = BrokerError::ClientError(rocketmq_client_rust::error::MQClientError::IllegalArgument( "client error".to_string(), )); assert_eq!(format!("{}", error), "Client error: client error"); }rocketmq-broker/src/out_api/broker_outer_api.rs (3)
60-61: LGTM! Consider grouping related imports.The move to a dedicated
broker_errormodule improves error handling organization. Consider grouping these error-related imports together with other error handling imports for better code organization.- use crate::broker_error::BrokerError; - use crate::broker_error::BrokerError::BrokerRemotingError; + use crate::broker_error::{ + BrokerError, + BrokerError::BrokerRemotingError, + };
370-370: LGTM! Consider adding error context.The use of
BrokerRemotingErrorvariant improves error type safety. Consider adding context about the operation being performed when wrapping the error.- Err(BrokerRemotingError(e)) + Err(BrokerRemotingError(e) + .with_context(|| format!("Failed to lock batch MQ at address: {}", addr)))
405-405: LGTM! Consider adding error context for consistency.The error handling is consistent with
lock_batch_mq_async. Consider adding operation context here as well.- Err(BrokerRemotingError(e)) + Err(BrokerRemotingError(e) + .with_context(|| format!("Failed to unlock batch MQ at address: {}", addr)))

25-25: LGTM! Module rename improves code organization.
The renaming from error to broker_error makes the module's purpose more specific and clearer, which is a good practice for large codebases.
Also applies to: 36-36
25-25: Verify the module rename impact across the crate.
Let's ensure all references to the old module name have been updated consistently.
Also applies to: 36-36
✅ Verification successful
All references to the error module have been correctly updated to broker_error
The verification shows that:
- All imports consistently use
broker_error::BrokerError - No references to the old module name
errorremain - The error type is properly defined in
broker_error.rs - All usages across the codebase reference the correct module path
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Check for any remaining references to the old error module name
# that might have been missed during the refactor.
# Search for any remaining references to the old module name
echo "Checking for old 'error' module references..."

23-23: Verify all usages of the renamed variant
The rename from BrokerClientError to BrokerRemotingError is a breaking change. Let's verify that all usages have been updated.
✅ Verification successful
Let me try a different search strategy to verify the variant rename.
Variant rename has been properly implemented
The search results confirm that:
- The new
BrokerRemotingErrorvariant is consistently used across the codebase - No occurrences of the old variant name
BrokerClientErrorwere found - The variant is properly used in error handling paths in multiple files including:
broker_error.rs(definition and tests)broker_outer_api.rs(error handling)broker_to_client.rs(error propagation)

25-26: LGTM: Error imports are properly organized
The imports correctly reflect the new error handling structure, importing both BrokerCommonError and BrokerRemotingError variants from the BrokerError enum.
41-41: LGTM: Error mapping is semantically improved
The change from BrokerClientError to BrokerRemotingError better represents the nature of the error (network/communication errors).
Let's verify consistent error handling across the codebase:
✅ Verification successful
Let me gather more information about error handling patterns in the codebase to ensure consistency.
Based on the search results, I can now generate the final response as we have sufficient evidence about error handling patterns in the codebase.
Error handling change is consistent with codebase patterns
The change to BrokerRemotingError aligns with the established error handling patterns:
BrokerRemotingErroris consistently used across the codebase for wrapping remoting/network errors- The error mapping follows the same pattern in other similar contexts (e.g., in
broker_outer_api.rs) - The error type is properly defined in the error hierarchy (
broker_error.rs)

370-370: Verify consistent error handling across the codebase.
Let's verify that the new error handling pattern is consistently applied across the codebase.
Also applies to: 405-405
✅ Verification successful
Let me generate additional scripts to get a more comprehensive view of the error handling patterns.
Based on the gathered information, I can now provide the final response:
Error handling is consistently implemented across the broker crate
The error handling pattern using BrokerRemotingError is consistently applied:
- Properly defined in
broker_error.rswith#[from]derive macro for automatic conversion - Consistently used in both
broker_outer_api.rsandbroker_to_client.rs - Error type is properly propagated through the crate's custom
Result<T>type - No instances of inconsistent or missed error handling patterns found

💡 Codebase verification
The 100ms timeout for transaction state checks is too short compared to other timeouts in the codebase
The verification reveals that the 100ms timeout for send_one_way in transaction state checks is inconsistent with other timeout configurations in the codebase:
- The default transaction timeout in
BrokerConfigis set to 6000ms (6 seconds) - Other RPC operations like producer's
send_msg_timeoutdefault to 3000ms - The broker's
forward_timeoutis set to 3000ms
The current 100ms timeout is significantly lower than these values and could lead to unnecessary transaction verification failures.
🔗 Analysis chain
Consider reviewing the timeout value for transaction state checks
While the error handling change to BrokerRemotingError is appropriate, the 100ms timeout for send_one_way in transaction state verification seems quite short. This could lead to unnecessary failures in high-load scenarios or when network latency is higher than usual.
Let's check if this timeout value is consistent with other transaction-related operations:
Consider increasing the timeout value or making it configurable based on the deployment environment and network conditions.

The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Check timeout values used in transaction-related operations
# Search for send_one_way calls with timeout values
echo "Checking timeout values in send_one_way calls:"
