1979	This breaks test-audit-path.t on macOS. In the test "attack /tmp/test", we call this codepath with f == '/tmp/test'. util.finddirs finds '/tmp', which on macOS is a symlink to /private/tmp, so L1940 is true and on L1941 we try to unlink /tmp. @mbthomas Is it intentional that we try to unlink symlinks to directories here? If not, we can fix this with: - if wvfs.isfileorlink(p): + if wvfs.isfileorlink(p) and not wvfs.isdir(p):
