Description

When a client sends messages to multiple topics, the statistics information can only output the results of one topic for a single client. After reviewing the code, I found that the problem lies in the break statement on line 305 of the client_v2.go file. Can you explain why this break statement is added?

for topic, count := range c.pubCounts {
	if len(topicName) > 0 && topic != topicName {
		continue
	}
	pubCounts = append(pubCounts, PubCount{
		Topic: topic,
		Count: count,
	})
	break   **//  What does this break statement do?**
}

Research direction
The issue is in client v2.go, line 305, where a break statement inside a loop over c.pubCounts causes only the first topic to be recorded. To fix, remove the break so that all topics are iterated and appended to pubCounts. No other changes are needed, and the fix is isolated to that single line.
