[PATCH 04/30] get_ref_dir(): require that the dirname argument ends in '/'

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


From: Michael Haggerty <mhagger@xxxxxxxxxxxx>

This removes some conditional code and makes it consistent with the
way that direntry names are stored.  Please note that this function is
never used on the top-level .git directory; it is always called for
directories at level .git/refs or deeper.
