321-337: Consider adding error handling for the broker permission operations.While the optimizations are good, both methods should consider handling potential errors that might occur during the permission operations, such as:
- Invalid broker names
- Concurrent modification conflicts
- System-level errors
Consider wrapping the return values in a Result type:
-fn wipe_write_perm_of_broker(&mut self, request: RemotingCommand) -> RemotingCommand { +fn wipe_write_perm_of_broker(&mut self, request: RemotingCommand) -> Result<RemotingCommand, Error> { let request_header = request .decode_command_custom_header::<WipeWritePermOfBrokerRequestHeader>() .expect("decode WipeWritePermOfBrokerRequestHeader failed"); - let wipe_topic_cnt = self + let wipe_topic_cnt = self .route_info_manager - .wipe_write_perm_of_broker_by_lock(&request_header.broker_name); - RemotingCommand::create_response_command() - .set_command_custom_header(WipeWritePermOfBrokerResponseHeader::new(wipe_topic_cnt)) + .wipe_write_perm_of_broker_by_lock(&request_header.broker_name) + .map_err(|e| Error::PermissionError(e.to_string()))?; + Ok(RemotingCommand::create_response_command() + .set_command_custom_header(WipeWritePermOfBrokerResponseHeader::new(wipe_topic_cnt))) }rocketmq-namesrv/src/route/route_info_manager.rs (1)
696-706: Improved error handling with early return.The implementation now properly checks for the existence of queue data before attempting to modify permissions. This prevents potential issues with missing queue data.
Consider adding debug logging when queue data is not found to help with troubleshooting:
if qd.is_none() { + debug!("Queue data not found for broker: {}", broker_name); continue; }

321-326: LGTM! Optimization looks good.
The change to pass a reference to broker_name directly to wipe_write_perm_of_broker_by_lock is a good optimization that:
- Avoids unnecessary string operations
- Improves thread safety by using immutable references
332-337: LGTM! Optimization looks good.
Similarly, the change to pass a reference to broker_name directly to add_write_perm_of_broker_by_lock is a good optimization that:
- Avoids unnecessary string operations
- Improves thread safety by using immutable references

678-684: LGTM! Performance optimization with inline attribute.
The addition of #[inline] attribute is a good optimization for this frequently called method. The implementation correctly uses a write lock to ensure thread safety while modifying broker permissions.
687-692: LGTM! Consistent implementation with wipe_write_perm.
The method follows the same pattern as wipe_write_perm_of_broker_by_lock, using write lock and inline attribute for optimization.
