Method readLine

plumbing/object/commit_scanner.go:52–63

readLine returns the next line from the buffer, transparently consuming any line that was previously pushed back by a state that decided not to handle it.

()

// line that was previously pushed back by a state that decided not to handle
// it.
func (s *commitScanner) readLine() ([]byte, error) {
	if s.pending != nil {
		line, err := s.pending, s.pendingErr
		s.pending, s.pendingErr = nil, nil
		return line, err
	}
	line, err := s.r.ReadBytes('\n')
	if err != nil && err != io.EOF {
		return line, err
	}
	return line, err
}

// pushBack stashes an unconsumed line so the next state's readLine call sees
// it. Only one line can be pushed back at a time.
