The option can be used to check if read-tree with the same set of other options like "-m" and "-u" would succeed without actually changing either the index or the working tree. The relevant tests in the t10?? range were extended to do a read-tree -n before the real read-tree to make sure neither the index nor any local files were changed with -n and the same exit code as without -n is returned. The helper functions added for that purpose reside in the new t/lib-read-tree.sh file. The only exception is #13 in t1004 ("unlinking an un-unlink-able symlink"). As this is an issue of wrong directory permissions it is not detected with -n. Signed-off-by: Jens Lehmann <Jens.Lehmann@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
