rocketmq-client/src/lib.rs (1)

23-27: Consider documenting the error handling architecture

Since this is part of a larger error handling refactoring effort, it would be beneficial to add documentation explaining the new error handling architecture and the rationale behind separating client errors.

Consider adding a module-level documentation comment above pub mod client_error explaining:

  • The purpose of the client error module
  • How it fits into the overall error handling strategy
  • Any guidelines for error handling in the codebase
+/// Client-specific error types and handling mechanisms.
+/// 
+/// This module contains error types specific to RocketMQ client operations,
+/// providing detailed error information for client-side operations.
 pub mod client_error;
rocketmq-tools/src/tools_error.rs (1)

22-22: Consider adding migration guide documentation

Since this changes the error module path, which could be a breaking change, consider documenting the migration path for users.

Would you like me to help create a migration guide section for the documentation?

rocketmq-broker/src/broker_error.rs (1)

Line range hint 39-65: Add test coverage for ClientError variant

While the error enum has good test coverage for other variants, there's no test case for the ClientError variant. Consider adding a test to maintain consistency with the existing test pattern.

 #[cfg(test)]
 mod tests {
     use rocketmq_remoting::remoting_error::RemotingError;
+    use rocketmq_client_rust::client_error::MQClientError;
     use super::*;

+    #[test]
+    fn client_error_displays_correctly() {
+        let error = BrokerError::ClientError(MQClientError::new("client error"));
+        assert_eq!(format!("{}", error), "Client error: client error");
+    }

     // ... existing tests ...
 }
rocketmq-client/src/producer/request_future_holder.rs (2)

68-71: Enhance error message with request details

While the structured error handling with error codes is good, the error message could be more informative by including request-specific details.

 let cause = Box::new(RequestTimeoutError(RequestTimeoutErr::new_with_code(
     ClientErrorCode::REQUEST_TIMEOUT_EXCEPTION,
-    "request timeout, no reply message.",
+    &format!("request timeout after {}ms, no reply message received", rf.get_timeout_milliseconds()),
 )));

Line range hint 1-108: Architecture maintains thread safety with improved error handling

The refactored error handling integrates well with the existing architecture:

  • Preserves thread-safe request future management with Arc/RwLock
  • Maintains proper async/await patterns
  • Cleanly separates error handling from business logic

Consider documenting the error handling patterns used here in the crate's documentation to ensure consistent usage across the codebase.

rocketmq-client/src/utils/message_util.rs (1)

76-82: Consider adding documentation for error scenarios.

To improve maintainability, consider adding documentation comments that describe:

  • When this error can occur
  • How to handle or recover from this error
  • Any specific conditions that might trigger this error

Example documentation:

/// Creates a reply message from a request message.
///
/// # Errors
///
/// Returns `ClientErrorCode::CREATE_REPLY_MESSAGE_EXCEPTION` when:
/// - The cluster property is missing in the request message
/// - The request message doesn't contain required reply properties
rocketmq-client/src/implementation/mq_admin_impl.rs (2)

Line range hint 123-125: Track unimplemented methods

The search_offset method is marked as unimplemented. This should be tracked and implemented to complete the API.

Would you like me to create a GitHub issue to track the implementation of this method?


Line range hint 99-102: Consider improving error handling for Option unwrapping

Using expect() for unwrapping Options could lead to runtime panics. Consider using proper error propagation instead.

Consider this pattern:

-        let client = self.client.as_mut().expect("client is None");
+        let client = self.client.as_mut()
+            .ok_or_else(|| MQClientErr(ClientErr::new("Client not initialized".to_string())))?;
rocketmq-client/src/base/validators.rs (1)

64-67: Consider consolidating error codes in check_message method

The method consistently uses ResponseCode::MessageIllegal for different validation failures. Consider creating specific error codes for each validation case to improve error handling granularity.

+ // Consider adding these constants to ResponseCode
+ const MESSAGE_BODY_NULL: i32 = /* new code */;
+ const MESSAGE_BODY_EMPTY: i32 = /* new code */;
+ const MESSAGE_BODY_OVERSIZED: i32 = /* new code */;
+ const MESSAGE_INVALID_DISPATCH: i32 = /* new code */;

  if msg.get_body().is_none() {
-     return Err(MQClientErr(ClientErr::new_with_code(
-         ResponseCode::MessageIllegal as i32,
+     return Err(MQClientErr(ClientErr::new_with_code(
+         MESSAGE_BODY_NULL,
          "the message body is null".to_string(),
      )));
  }

rocketmq-client/src/consumer/store/local_file_offset_store.rs (2)

92-95: Consider enhancing the error message with file path context.

The error handling improvement is good, but consider including the file path in the error message for better debugging context.

-                    "Failed to deserialize local offset: {}",
-                    e
+                    "Failed to deserialize local offset from '{}': {}",
+                    self.store_path, e

92-95: Consider architectural improvements for error handling consistency.

Several improvements could enhance maintainability and consistency:

  1. Create a dedicated method for file path construction to avoid duplication
  2. Establish consistent error message formatting across the codebase
  3. Consider creating error constants or an error factory for common error cases

Example implementation:

impl LocalFileOffsetStore {
    fn get_backup_path(&self) -> String {
        format!("{}.bak", self.store_path)
    }

    fn create_deserialization_error(&self, path: &str, error: impl std::error::Error) -> MQClientError {
        MQClientError::MQClientErr(ClientErr::new(format!(
            "Failed to deserialize offset from '{}': {}",
            path, error
        )))
    }
}

Also applies to: 107-110

rocketmq-client/src/consumer/pull_callback.rs (1)

179-182: LGTM! Consider adding documentation for the new error type

The refactoring from MQBrokerError to MQClientBrokerError maintains the existing error handling logic while improving error type specificity. The changes handle both subscription and flow control cases appropriately.

Consider adding documentation comments explaining:

  • The scenarios where MQClientBrokerError is used
  • The difference between the old and new error types
  • The relationship between broker errors and client errors
 match er {
+    // MQClientBrokerError represents broker-related errors that occur during client operations
     MQClientError::MQClientBrokerError(broker_error) => {

Also applies to: 210-212

rocketmq-client/src/consumer/store/remote_broker_offset_store.rs (2)

113-116: Fix indentation for consistency

While the error handling logic is correct, the indentation of these lines is inconsistent with the rest of the file.

-            Err(MQClientError::MQClientErr(ClientErr::new(format!(
-                "broker not found, {}",
-                mq.get_broker_name()
-            ))))
+        Err(MQClientError::MQClientErr(ClientErr::new(format!(
+            "broker not found, {}",
+            mq.get_broker_name()
+        ))))

323-326: Consider extracting common error handling

This error handling pattern is identical to the one in fetch_consume_offset_from_broker. Consider extracting it into a helper method to avoid duplication.

+ impl RemoteBrokerOffsetStore {
+     fn broker_not_found_error(&self, broker_name: &str) -> MQClientError {
+         MQClientError::MQClientErr(ClientErr::new(format!(
+             "broker not found, {}",
+             broker_name
+         )))
+     }
+ }

- Err(MQClientError::MQClientErr(ClientErr::new(format!(
-     "broker not found, {}",
-     mq.get_broker_name()
- ))))
+ Err(self.broker_not_found_error(mq.get_broker_name()))

Also, fix the indentation to match the rest of the file:

-            Err(MQClientError::MQClientErr(ClientErr::new(format!(
-                "broker not found, {}",
-                mq.get_broker_name()
-            ))))
+        Err(MQClientError::MQClientErr(ClientErr::new(format!(
+            "broker not found, {}",
+            mq.get_broker_name()
+        ))))
rocketmq-client/src/consumer/consumer_impl/pull_api_wrapper.rs (1)

364-367: Enhance error message with more context

While the error handling follows the new pattern, the error message could be more informative for debugging purposes.

Consider enhancing the error message:

-            Err(MQClientErr(ClientErr::new(format!(
-                "The broker[{}] not exist",
-                mq.get_broker_name(),
-            ))))
+            Err(MQClientErr(ClientErr::new(format!(
+                "Failed to find broker[{}] in subscription. Broker might be offline or not registered.",
+                mq.get_broker_name(),
+            ))))
rocketmq-client/src/consumer/consumer_impl/re_balance/rebalance_push_impl.rs (1)

276-278: Enhance error messages with specific failure reasons

The error messages could be more descriptive about the actual failure reasons:

  1. For the default consumer implementation check, specify why it might be None
  2. For the system error case, include the actual offset value in the error message
- return Err(MQClientError::MQClientErr(ClientErr::new(
-     "default_mqpush_consumer_impl is none",
- )));
+ return Err(MQClientError::MQClientErr(ClientErr::new(
+     "DefaultMQPushConsumerImpl is not initialized or has been dropped",
+ )));

- return Err(MQClientError::MQClientErr(ClientErr::new_with_code(
-     ResponseCode::SystemError.into(),
-     "Failed to query consume offset from offset store",
- )));
+ return Err(MQClientError::MQClientErr(ClientErr::new_with_code(
+     ResponseCode::SystemError.into(),
+     format!("Invalid consume offset {} returned from store", result),
+ )));

Also applies to: 373-376

rocketmq-client/src/consumer/consumer_impl/re_balance/rebalance_impl.rs (1)

Line range hint 12-24: Consider further refactoring opportunities

The code could benefit from additional refactoring to improve maintainability and error handling:

  1. Extract the complex rebalancing logic into smaller, focused methods
  2. Create a common error handling pattern for timeout and broker communication errors
  3. Consider using a builder pattern for the complex initialization in RebalanceImpl

Example for error handling extraction:

+ fn handle_query_timeout(&self, topic: &CheetahString, retry_times: u32) -> bool {
+     if retry_times >= TIMEOUT_CHECK_TIMES {
+         let mut topic_client_rebalance = self.topic_client_rebalance.write().await;
+         topic_client_rebalance.insert(topic.clone(), topic.clone());
+         return false;
+     }
+     true
+ }

  match self.client_instance.as_mut().unwrap().query_assignment(...).await {
      Ok(_) => { ... }
      Err(e) => match e {
-         MQClientError::RequestTimeoutError(_) => {}
+         MQClientError::RequestTimeoutError(_) => self.handle_query_timeout(topic, retry_times),
          _ => {
              error!("tryQueryAssignment error {}.", e);
              let mut topic_client_rebalance = self.topic_client_rebalance.write().await;

Also applies to: 167-173

rocketmq-client/src/producer/default_mq_producer.rs (1)

494-496: Consider adding more context to the error message

While the error handling has been improved by using ClientErr::new, the error message could be more informative by including the actual error details from err.

Consider this improvement:

-                Err(MQClientErr(ClientErr::new(
-                    "Failed to initiate the MessageBatch",
-                )))
+                Err(MQClientErr(ClientErr::new(
+                    format!("Failed to initiate the MessageBatch: {}", err)
+                )))
rocketmq-client/src/factory/mq_client_instance.rs (1)

Line range hint 976-989: Consider extracting the long error message to a constant

While the error handling is well-structured, the long error message could be moved to a constant for better maintainability and reusability.

+ const UNSUPPORTED_FILTER_ERROR: &str = 
+    "Check client in broker error, maybe because you use {} to filter message, \
+     but server has not been upgraded to support!This error would not affect \
+     the launch of consumer, but may has impact on message receiving if you \
+     have use the new features which are not supported by server, please check \
+     the log!";

  match e {
      MQClientErr(err) => {
          return Err(MQClientErr(err));
      }
      _ => {
-         let desc = format!(
-             "Check client in broker error, maybe because you use {} to \
-              filter message, but server has not been upgraded to support!\
-              This error would not affect the launch of consumer, but may \
-              has impact on message receiving if you have use the new \
-              features which are not supported by server, please check the log!",
-             subscription_data.expression_type
-         );
+         let desc = format!(UNSUPPORTED_FILTER_ERROR, 
+             subscription_data.expression_type);
          return Err(MQClientErr(ClientErr::new(desc)));
      }
  }
rocketmq-client/src/consumer/consumer_impl/default_mq_push_consumer_impl.rs (1)

Line range hint 451-611: Consider extracting repeated error handling pattern into a helper function.

While the error handling has been properly refactored to use ClientErr::new, there's significant repetition in the error handling pattern. Consider extracting the common pattern into a helper function to improve maintainability.

Example implementation:

fn config_error(message: impl Into<String>) -> Result<()> {
    Err(MQClientError::MQClientErr(ClientErr::new(format!(
        "{}{}",
        message.into(),
        FAQUrl::suggest_todo(FAQUrl::CLIENT_PARAMETER_CHECK_URL)
    ))))
}

This would simplify the validation checks to:

if self.consumer_config.consumer_group.is_empty() {
    return config_error("consumer_group is empty");
}
rocketmq-client/src/client_error.rs (2)

117-119: Consider making error_message a required field

The error_message field is always set to Some(error_message) in the constructors. Making it a non-optional field can simplify the code and reduce the need for Option wrapping.

Apply this diff to change error_message to a mandatory field:

 pub struct ClientErr {
     response_code: i32,
-    error_message: Option<CheetahString>,
+    error_message: CheetahString,
     message: CheetahString,
 }

 impl ClientErr {
     pub fn new(error_message: impl Into<CheetahString>) -> Self {
         let error_message = error_message.into();
         let message = FAQUrl::attach_default_url(Some(error_message.as_str()));
         Self {
             response_code: -1,
-            error_message: Some(error_message),
+            error_message,
             message: CheetahString::from(message),
         }
     }

Repeat similar changes for MQBrokerErr and RequestTimeoutErr if appropriate.


24-44: Ensure consistency in error messages and variants

The MQClientError enum contains variants with different patterns of error messages. Consider standardizing the error messages for consistency and better maintainability.

For example, you can refactor OffsetNotFoundError to include a structured error type similar to other variants:

-    #[error("Client exception occurred: CODE:{0}, broker address:{1}, Message:{2}")]
-    OffsetNotFoundError(i32, String, String),
+    #[error("{0}")]
+    OffsetNotFoundError(OffsetNotFoundErr),

Define OffsetNotFoundErr as:

#[derive(Error, Debug)]
#[error("{message}")]
pub struct OffsetNotFoundErr {
    response_code: i32,
    broker_addr: CheetahString,
    error_message: CheetahString,
    message: CheetahString,
}

87-91: Streamline Import Statements for Error Types

The imports for error types can be consolidated to improve readability and maintainability.

Apply this diff to group the related imports:

-use crate::client_error::ClientErr;
-use crate::client_error::MQBrokerErr;
-use crate::client_error::MQClientError;
-use crate::client_error::MQClientError::MQClientBrokerError;
-use crate::client_error::MQClientError::MQClientErr;
+use crate::client_error::{
+    ClientErr,
+    MQBrokerErr,
+    MQClientError::{self, MQClientBrokerError, MQClientErr},
+};

257-266: Simplify Error Handling Logic in get_topic_route_info_from_name_server_detail

The error is returned twice with similar code. This redundancy can be eliminated to streamline the function.

Refactor the error handling to return the error directly within the match arm:

             _ => {
-                return Err(MQClientError::MQClientErr(ClientErr::new_with_code(
-                    code,
-                    result.remark().cloned().unwrap_or_default().to_string(),
-                )))
+                Err(MQClientError::MQClientErr(ClientErr::new_with_code(
+                    code,
+                    result.remark().cloned().unwrap_or_default().to_string(),
+                )))
             }
         }
-        Err(MQClientError::MQClientErr(ClientErr::new_with_code(
-            code,
-            result.remark().cloned().unwrap_or_default().to_string(),
-        )))

687-692: Refactor Error Creation in send_heartbeat

The construction of the error can be simplified to enhance readability.

Consider creating a helper function or method to construct MQClientError from the response:

-    Err(MQClientError::MQClientBrokerError(
-        MQBrokerErr::new_with_broker(
-            response.code(),
-            response.remark().map_or("".to_string(), |s| s.to_string()),
-            addr.to_string(),
-        ),
-    ))
+    Err(MQClientError::from_broker_response(&response, addr))

Assuming you implement from_broker_response method accordingly.


772-777: Eliminate Redundant Error Return in get_consumer_id_list_by_group

There's an unnecessary return statement in the match arm that can be removed for cleaner code.

Refactor to directly return the error without the return keyword:

         _ => {
-            return Err(MQClientError::MQClientBrokerError(
+            Err(MQClientError::MQClientBrokerError(
                 MQBrokerErr::new_with_broker(
                     response.code(),
                     response.remark().map_or("".to_string(), |s| s.to_string()),
                     addr.to_string(),
                 ),
             ))
-            );
         }

874-879: Enhance Error Messaging in query_consumer_offset

The error message lacks context, which can make debugging more difficult.

Include additional details such as the topic and consumer group:

-    Err(MQClientError::MQClientBrokerError(
+    Err(MQClientError::MQClientBrokerError(MQBrokerErr::new_with_broker(
         response.code(),
         response.remark().map_or("".to_string(), |s| s.to_string()),
         addr.to_string(),
+        format!("Failed to query offset for topic '{}' and consumer group '{}'", request_header.topic, request_header.consumer_group)
     )))

1043-1047: Refactor Error Handling in consumer_send_message_back

To reduce code duplication, consider creating a helper function for constructing broker errors.

Implement a method to handle error creation:

-    Err(MQClientBrokerError(MQBrokerErr::new_with_broker(
-        response.code(),
-        response.remark().map_or("".to_string(), |s| s.to_string()),
-        addr.to_string(),
-    )))
+    Err(MQClientError::from_broker_response(&response, addr))

1228-1232: Simplify Error Construction in get_max_offset

You can refactor the error creation to enhance code clarity and reduce repetition.

Use a common error handling method or macro to construct the error:

-    Err(MQClientBrokerError(MQBrokerErr::new_with_broker(
-        response.code(),
-        response.remark().map_or("".to_string(), |s| s.to_string()),
-        addr.to_string(),
-    )))
+    Err(MQClientError::from_broker_response(&response, addr))

1314-1318: Enhance Error Information in query_assignment

Providing more context in error messages aids in debugging and usability.

Include the topic, consumer group, and other relevant details in the error message:

-    Err(MQClientBrokerError(MQBrokerErr::new_with_broker(
-        response.code(),
-        response.remark().map_or("".to_string(), |s| s.to_string()),
-        addr.to_string(),
-    )))
+    Err(MQClientBrokerError(MQBrokerErr::new_with_broker(
+        response.code(),
+        format!(
+            "Failed to query assignment for topic '{}', consumer group '{}': {}",
+            request_body.topic,
+            request_body.consumer_group,
+            response.remark().map_or("".to_string(), |s| s.to_string())
+        ),
+        addr.to_string(),
+    )))
rocketmq-client/src/producer/producer_impl/default_mq_producer_impl.rs (12)

62-67: Consolidate imports from client_error module

Multiple items are being imported individually from the client_error module. For better readability and maintainability, consider consolidating these imports.

Apply this diff to consolidate the imports:

-use crate::client_error::ClientErr;
-use crate::client_error::MQClientError;
-use crate::client_error::MQClientError::MQClientErr;
-use crate::client_error::MQClientError::RemotingTooMuchRequestError;
-use crate::client_error::MQClientError::RequestTimeoutError;
-use crate::client_error::RequestTimeoutErr;
+use crate::client_error::{
+    ClientErr,
+    MQClientError::{self, MQClientErr, RemotingTooMuchRequestError, RequestTimeoutError},
+    RequestTimeoutErr,
+};

262-266: Clarify error message for topic mismatch

The error message could be more precise to aid in debugging when the message topic does not match the message queue topic.

Consider rephrasing the error message:

-return Err(MQClientError::MQClientErr(ClientErr::new(format!(
-    "message topic [{}] is not equal with message queue topic [{}]",
-    msg.get_topic(),
-    mq.get_topic()
-))));
+return Err(MQClientError::MQClientErr(ClientErr::new(format!(
+    "Message topic '{}' does not match the message queue topic '{}'",
+    msg.get_topic(),
+    mq.get_topic()
+))));

429-431: Improve null message queue selection error handling

The error returned when select message queue returns null could include more context or suggestions.

Update the error message to provide additional guidance:

-return Err(MQClientError::MQClientErr(ClientErr::new(
-    "select message queue return null.",
-)));
+return Err(MQClientError::MQClientErr(ClientErr::new(
+    "Message queue selection returned None. Ensure that the selector function is correctly implemented and returns a valid MessageQueue.",
+)));

Line range hint 775-798: Handle specific error variants explicitly

In the match statement handling errors, consider handling specific MQClientError variants explicitly to improve error granularity and future maintainability.

Adjust the match arms to handle each error variant:

-match err {
-    MQClientError::MQClientErr(_) => {
+    MQClientError::MQClientErr(ref client_err) => {
         // Handle MQClientErr
     }
-    MQClientError::MQClientBrokerError(ref er) => {
+    MQClientError::MQClientBrokerError(ref broker_err) => {
         // Handle MQClientBrokerError
     }
     // Add additional match arms for other error variants as needed
     _ => {
         return Err(err);
     }
}

878-913: Refactor repetitive error wrapping

The code repetitively wraps various MQClientError variants into MQClientErr with the same ClientErrorCode. This repetition can be reduced for cleaner code.

Simplify the error handling using a helper function or by matching multiple patterns:

-if let Some(err) = exception {
-    match err {
-        MQClientError::MQClientErr(_) |
-        MQClientError::RemotingTooMuchRequestError(_) |
-        MQClientError::MQClientBrokerError(_) |
-        MQClientError::RequestTimeoutError(_) |
-        MQClientError::OffsetNotFoundError(_, _, _) |
-        MQClientError::RemotingError(_) => {
-            Err(MQClientErr(ClientErr::new_with_code(
-                ClientErrorCode::BROKER_NOT_EXIST_EXCEPTION,
-                info,
-            )))
-        }
-        _ => {
-            unimplemented!("not support error type");
-        }
-    }
-} else {
-    Err(MQClientErr(ClientErr::new(info)))
-}
+if let Some(err) = exception {
+    match err {
+        MQClientError::MQClientErr(_)
+        | MQClientError::RemotingTooMuchRequestError(_)
+        | MQClientError::MQClientBrokerError(_)
+        | MQClientError::RequestTimeoutError(_)
+        | MQClientError::OffsetNotFoundError(_, _, _)
+        | MQClientError::RemotingError(_) => {
+            Err(MQClientErr(ClientErr::new_with_code(
+                ClientErrorCode::BROKER_NOT_EXIST_EXCEPTION,
+                info,
+            )))
+        }
+        _ => {
+            unimplemented!("Unsupported error type");
+        }
+    }
+} else {
+    Err(MQClientErr(ClientErr::new(info)))
+}

990-993: Handle missing broker address more gracefully

When the broker address is not found, consider providing more actionable guidance or retries.

Enhance the error handling to attempt to update routing information before failing:

-if broker_addr.is_none() {
-    return Err(MQClientError::MQClientErr(ClientErr::new(format!(
-        "The broker[{}] not exist",
-        broker_name,
-    ))));
+if broker_addr.is_none() {
+    // Attempt to refresh routing information
+    self.try_to_find_topic_publish_info(mq.get_topic_cs()).await;
+    broker_addr = self
+        .client_instance
+        .as_ref()
+        .unwrap()
+        .find_broker_address_in_publish(broker_name.as_ref())
+        .await;
+    if broker_addr.is_none() {
+        return Err(MQClientError::MQClientErr(ClientErr::new(format!(
+            "The broker '{}' does not exist after route refresh",
+            broker_name,
+        ))));
+    }
}

1287-1293: Ensure name server addresses are properly configured

The error message suggests no name server address is set. Provide additional instructions to guide users on how to set it.

Consider updating the error message:

-return Err(MQClientError::MQClientErr(ClientErr::new_with_code(
-    ClientErrorCode::NO_NAME_SERVER_EXCEPTION,
-    format!(
-        "No name remoting_server address, please set it. {}",
-        FAQUrl::suggest_todo(FAQUrl::NAME_SERVER_ADDR_NOT_EXIST_URL)
-    ),
-)));
+return Err(MQClientError::MQClientErr(ClientErr::new_with_code(
+    ClientErrorCode::NO_NAME_SERVER_EXCEPTION,
+    "No name server address is configured. Please set the name server address using 'client_config.set_namesrv_addr(...)' or ensure that the 'NAMESRV_ADDR' environment variable is set.".to_string(),
+)));

1341-1345: Check producer service state before operation

The error message when the producer service state is not running can be more informative.

Update the error message to include the current service state:

-return Err(MQClientError::MQClientErr(ClientErr::new(format!(
-    "The producer service state not OK, {:?} {}",
-    self.service_state,
-    FAQUrl::suggest_todo(FAQUrl::CLIENT_SERVICE_NOT_OK)
-))));
+return Err(MQClientError::MQClientErr(ClientErr::new(format!(
+    "The producer service state is '{:?}', expected 'Running'. Please ensure the producer is started before sending messages.",
+    self.service_state
+))));

1395-1397: Handle None message queue selection

Consistently handle cases where message queue selection returns None, providing clear feedback to the caller.

Adjust the error handling:

-return Err(MQClientError::MQClientErr(ClientErr::new(
-    "select message queue return None.",
-)));
+return Err(MQClientError::MQClientErr(ClientErr::new(
+    "Message queue selection failed—received None. Please ensure the selector function is properly implemented.",
+)));

1550-1551: Avoid cloning error messages unnecessarily

Cloning error messages can be resource-intensive. Consider passing references where possible.

Refactor the error handling to avoid unnecessary cloning:

-request_response_future.set_cause(Box::new(MQClientError::MQClientErr(
-    ClientErr::new(error.to_string()),
-)));
+request_response_future.set_cause(Box::new(MQClientError::MQClientErr(
+    ClientErr::new(error.to_string()),
+)));

Ensure error implements ToString efficiently.


1900-1903: Provide detailed error when transaction message sending fails

When sending a message in a transaction fails, include more context in the error to aid troubleshooting.

Improve the error message:

-return Err(MQClientErr(ClientErr::new(format!(
-    "send message in transaction error, {}",
-    e
-))));
+return Err(MQClientErr(ClientErr::new(format!(
+    "Failed to send message in transaction: {}. Please check network connectivity and broker availability.",
+    e
+))));

2257-2262: Avoid duplicate producer group registration

The error message indicates that the producer group has been registered before. Suggest steps to resolve this issue.

Update the error message:

return Err(MQClientError::MQClientErr(ClientErr::new(format!(
    "The producer group '{}' has already been registered. Please use a unique producer group name or ensure previous instances are properly shut down.",
    self.producer_config.producer_group(),
))));

23-23: LGTM: Import path updated correctly

The import statement has been properly updated to use the new client_error module path.


27-27: Verify all references to the old error module

The module renaming from error to client_error is more descriptive and better reflects its purpose. However, we should ensure all references are updated.

✅ Verification successful

Let me gather more specific information about the imports to verify if they are correctly using the new module name.


All references to the error module have been correctly updated

Based on the verification results, all imports are correctly using the new client_error module name. Every reference to MQClientError is properly imported from crate::client_error, and there are no remaining references to the old error module. The module is also correctly defined in lib.rs as client_error.

Line range hint 30-54: Well-structured error handling implementation

The error handling implementation follows good practices:

  • Clear, descriptive error messages
  • Proper validation of all input parameters
  • Early returns with Result type
  • Appropriate logging for debugging purposes

26-26: Verify consistency of error module reorganization

The import path change from error to client_error aligns with the PR's error handling refactoring objective.

Let's verify if this change is consistently applied across the codebase:

✅ Verification successful

Import path change is consistently applied across the codebase

35-35: Verify the new module path exists

The change to use client_error::MQClientError aligns with the error handling refactoring objective. However, let's verify that this new module path exists and is properly exported.

✅ Verification successful

Let me gather more information to verify the error type definition.


Based on the search results, I can now generate the final response since I have verified that:

  1. The MQClientError enum exists in rocketmq-client/src/client_error.rs
  2. The module is properly exported in rocketmq-client/src/lib.rs with pub mod client_error
  3. The error type is used extensively throughout the codebase

The new module path is correctly structured and exported

The change to use client_error::MQClientError is valid as the module has been properly organized and exported. The new path aligns with Rust's module organization best practices by having error types in a dedicated module.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Verify the new client_error module exists and is properly exported

# Check if the new module path exists in the client crate

68-71: LGTM: Improved error handling structure

The refactoring to use ClientErrorCode and structured error types is a good improvement:

  • Uses typed error codes instead of raw strings/numbers
  • Provides a clear error construction pattern
  • Maintains proper error boxing for trait objects

28-29: Verify error type naming convention consistency

The imports show two different naming patterns (RequestTimeoutError and RequestTimeoutErr). This might indicate inconsistent error type naming across the codebase.

✅ Verification successful

Error type naming follows consistent pattern in the codebase

The error handling pattern is actually consistent across the codebase:

  • RequestTimeoutErr is a struct that holds the error details
  • RequestTimeoutError is a variant of the MQClientError enum that wraps the RequestTimeoutErr struct
  • This pattern is consistently used with other error types too (e.g., MQBrokerErr, ClientErr)

The imports in the file are correct and follow the established error handling pattern in the codebase.

  • Consistent error wrapping pattern

Let's verify the error code definition:

✅ Verification successful

Let me gather more information about the error code implementation to ensure it's properly defined as a constant and not an enum variant.


Error code is properly defined and used correctly

The error code CREATE_REPLY_MESSAGE_EXCEPTION is:

  • Properly defined as a constant with value 10007 in ClientErrorCode

40-54: Verify input sanitization in group validation

While the code checks for illegal characters, let's verify that the pattern ^[%|a-zA-Z0-9_-]+$ is sufficient for preventing injection attacks.

✅ Verification successful

Input validation implementation is secure and well-tested

The implementation in topic.rs shows a robust and secure approach to input validation:

  • Uses a pre-computed bitmap (VALID_CHAR_BIT_MAP) for efficient character validation
  • Validates each character individually against the allowed set
  • Implements proper length checks
  • Has comprehensive test coverage including edge cases
  • Uses a whitelist approach allowing only specific characters: %|-_ and alphanumeric
  • The validation is used consistently across both topic and group names

The pattern ^[%|a-zA-Z0-9_-]+$ is correctly implemented and sufficient for preventing injection attacks as it:

  • Strictly limits the allowed character set
  • Doesn't allow any special characters that could be used for injection
  • Enforces validation on the entire string (not partial matches)

Based on the code analysis, I can now generate the final response:

Simple Success/Failure Response is Sufficient for set_message_request_mode

The current error handling is appropriate for this method. The function sets the message request mode (Pull/Pop) for a consumer group and topic, where only a basic success/failure response is needed. No special error code handling is required because:

  1. The operation is a simple configuration update
  2. The implementation shows only two possible outcomes:
    • Success (ResponseCode::Success): Configuration applied
    • Any other response code: Configuration failed (returns a ClientErr with the code and remark)
  3. The MessageRequestMode enum is used only for mode selection (Pull/Pop) and doesn't require specific error handling

🛠️ Refactor suggestion

Capture and include the underlying error information.

The error handler discards the actual error cause by using Err(_). This could make debugging more difficult.

🛠️ Refactor suggestion

Differentiate error messages for distinct failure cases

The same error message is used for two different failure scenarios, which could make debugging more difficult.

Consider differentiating the error messages:

-                Err(MQClientErr(ClientErr::new(format!(
-                    "Find Filter Server Failed, Broker Addr: {},topic:{}",
-                    broker_addr, topic
-                )))),
+                Err(MQClientErr(ClientErr::new(format!(
+                    "No available filter server found in list for broker[{}], topic[{}]",
+                    broker_addr, topic
+                )))),

-        Err(MQClientErr(ClientErr::new(format!(
-            "Find Filter Server Failed, Broker Addr: {},topic:{}",
-            broker_addr, topic
-        ))))
+        Err(MQClientErr(ClientErr::new(format!(
+            "No filter servers configured for broker[{}], topic[{}]",
+            broker_addr, topic
+        ))))

Reduce duplication: Extract repeated error message into a constant

The same error message "Failed to query consume offset from offset store" is duplicated in three places. Consider extracting it into a constant for better maintainability.

+ const OFFSET_QUERY_ERROR_MSG: &str = "Failed to query consume offset from offset store";

- return Err(MQClientError::MQClientErr(ClientErr::new_with_code(
-     ResponseCode::QueryNotFound.into(),
-     "Failed to query consume offset from offset store",
- )));
+ return Err(MQClientError::MQClientErr(ClientErr::new_with_code(

+     OFFSET_QUERY_ERROR_MSG,

⚠️ Potential issue

Fix potential dangling reference caused by .as_str() on a temporary String

Consistent with the previous issues, there's a dangling reference caused by .as_str() on a temporary String.

Apply this diff to fix the issue:

             let error_message = error_message.into();
-            let message = FAQUrl::attach_default_url(Some(
-                format!("CODE: {}  DESC: {}", response_code, error_message,).as_str(),
-            ));
+            let formatted_message = format!("CODE: {}  DESC: {}", response_code, error_message);
+            let message = FAQUrl::attach_default_url(Some(&formatted_message));

⚠️ Potential issue

Handle potential deadlocks or await issues

In the asynchronous callback, check if there is a potential for deadlocks or missed await keywords that might prevent the future from completing.

Review the asynchronous code to ensure all futures are properly awaited and there are no blocking calls in async contexts.

🛠️ Refactor suggestion

Synchronize error handling in callbacks

Ensure that error handling within callbacks is consistent and threadsafe, especially when interacting with shared state or futures.

Review the callback implementation to confirm thread safety and consistency.

🛠️ Refactor suggestion

Handle duplicate start calls gracefully

Starting the producer when it is already running should be idempotent or provide a clear message without causing an error.

Consider returning early without error if the service is already running:

if self.service_state == ServiceState::Running {
-    return Err(MQClientError::MQClientErr(ClientErr::new(
-        "The producer service state is Running",
-    )));
+    // Already running; no action needed
+    return Ok(());

⚠️ Potential issue

Avoid using default producer group name

Using the default producer group name can lead to conflicts. Enforce custom group names.

Ensure that a custom producer group name is provided:

if self.producer_config.producer_group() == DEFAULT_PRODUCER_GROUP {
    return Err(MQClientError::MQClientErr(ClientErr::new(format!(
        "The specified group name '{}' is reserved. Please specify a custom producer group name.",
