26-26: LGTM: Good use of SerdeJsonUtils for JSON serialization
Using the centralized SerdeJsonUtils for JSON serialization promotes consistency and maintainability.
Line range hint 41-82: Verify impact of removed ConfigManager methods
The removal of decode0, stop, and encode methods from the ConfigManager implementation needs verification to ensure no functionality is broken.
Let's check for any remaining usages of these methods:
| self.auto_clean(); | ||
| let wrapper = self.consumer_order_info_wrapper.lock(); | ||
| match pretty_format { | ||
| true => SerdeJsonUtils::to_json_pretty(&wrapper.table) | ||
| .expect("Failed to serialize consumer order info wrapper"), | ||
| false => serde_json::to_string(&wrapper.table) | ||
| .expect("Failed to serialize consumer order info wrapper"), | ||
| } |

🛠️ Refactor suggestion
Consider using Result instead of expect for error handling
The current implementation uses expect which could cause panics in production. Consider returning a Result type instead.
- fn encode_pretty(&self, pretty_format: bool) -> String {
+ fn encode_pretty(&self, pretty_format: bool) -> Result<String, serde_json::Error> {
self.auto_clean();
let wrapper = self.consumer_order_info_wrapper.lock();
match pretty_format {
- true => SerdeJsonUtils::to_json_pretty(&wrapper.table)
- .expect("Failed to serialize consumer order info wrapper"),
- false => serde_json::to_string(&wrapper.table)
- .expect("Failed to serialize consumer order info wrapper"),
+ true => SerdeJsonUtils::to_json_pretty(&wrapper.table),
+ false => serde_json::to_string(&wrapper.table),
}

💡 Codebase verification
Now I have enough context to provide the final response:
Implement auto_clean functionality to prevent memory leaks from stale order information
The auto_clean method should remove entries from ConsumerOrderInfoWrapper.table where OrderInfo.pop_time is older than CLEAN_SPAN_FROM_LAST (24 hours). The data structure shows:
- A HashMap of topic@group to order information
- Each OrderInfo contains
pop_timeandinvisible_time CLEAN_SPAN_FROM_LASTis defined as 24 hours in milliseconds
Example implementation should:
- Lock the wrapper
- Filter out entries where
current_time - pop_time > CLEAN_SPAN_FROM_LAST - Update the HashMap with the filtered entries
🔗 Analysis chain
Implement auto_clean functionality to prevent potential memory leaks
The auto_clean method is currently empty but is called during serialization. Based on the CLEAN_SPAN_FROM_LAST constant (24 hours), it appears this method should clean up old consumer order information.
Consider implementing the following:
- Remove entries older than CLEAN_SPAN_FROM_LAST
- Clean up any orphaned or completed orders
Let's verify the usage of auto_clean in other parts of the codebase:
Let me gather more context about the consumer order info manager to understand the data structure and cleaning requirements.
Let me check the ConsumerOrderInfoWrapper structure and any related data that needs cleaning:
