I gave ChatGPT the project's README and asked it to write Go code based on it. The code it produced was very similar in structure to the original, with many parts almost identical.

For example, what ChatGPT gave me:

  func (q *Queue) Enqueue(b []byte) error {
   if len(b) > maxBodySize {
     return fmt.Errorf("payload too large")
   }
   q.mu.Lock()
   defer q.mu.Unlock()

   if len(q.data) >= q.maxMsg || q.bytes+len(b) > q.maxB {
    return errors.New("queue full")
   }
   cp := append([]byte(nil), b...)
   q.data = append(q.data, cp)
   q.bytes += len(cp)
   atomic.AddUint64(&q.enqueueCnt, 1)
   return nil
  }

The project:

  func (q *queue) enqueue(b []byte) error {
   if len(b) > maxBody {
    return errors.New("payload too large")
   }
   q.mu.Lock()
   defer q.mu.Unlock()
   if len(q.data) >= maxMsgs || q.bytes+int64(len(b)) > maxBytes {
    return errors.New("queue full")
   }
   cp := append([]byte(nil), b...)
   q.data = append(q.data, cp)
   q.bytes += int64(len(cp))
   atomic.AddUint64(&enqueueCnt, 1)
   return nil
  }

Flagged this submission for that very reason.

More than a little
