It walks the path upwards (starting a 'four') and looks for a directory which contains a file called 'format' and a directory called 'db' on the OS filesystem (not in the versioned tree, of course). This directory is assumed to be the repository root. See svn_repos_find_root_path() in https://svn.apache.org/repos/asf/subversion/trunk/subversion/libsvn_repos/repos.c
