Code Review
This pull request adds documentation comments to the AllocateBatch method in random_allocator.go. The reviewer pointed out a contradiction in the comments regarding whether the method modifies shared state requiring a lock or only uses a local map. The documentation should be clarified to accurately describe what the lock protects.
| // This method is concurrency-safe as it acquires a lock before modifying the port allocation state. | ||
| // Note: The allocated ports are not persisted; they are only stored in the local map to avoid duplicates within the same batch. |
There was a problem hiding this comment.
There is a contradiction between line 75 and line 76:
- Line 75 states that the method "acquires a lock before modifying the port allocation state."
- Line 76 states that "allocated ports are not persisted; they are only stored in the local map."
Since the allocatedPorts map is local to the function invocation, it does not require synchronization. If a lock is indeed acquired, it is likely protecting a shared random number generator (which is not thread-safe in Go if using a custom rand.Rand) rather than any "port allocation state".
Please clarify the comment to accurately reflect what the lock protects to avoid misleading future maintainers.
