[patch by Paul Eggert] * tests/chmod/c-option: When double-quoting part of a word, prefer to double-quote the whole word. This is a bit easier to read (at least for me), and in some cases it avoids a shell bug with Tru64 4.0 sh reported by Nelson H. F. Beebe. For example, instead of "$abs_srcdir"/../setgid-check we now write "$abs_srcdir/../setgid-check". * tests/cp/cp-parents: Likewise. * tests/du/inaccessible-cwd: Likewise. * tests/du/long-from-unreadable: Likewise. * tests/install/basic-1: Likewise. * tests/install/trap: Likewise. * tests/misc/close-stdout: Likewise. * tests/mkdir/concurrent-1: Likewise. * tests/mkdir/p-1: Likewise. * tests/mkdir/p-3: Likewise. * tests/mkdir/parents: Likewise. * tests/mkdir/perm: Likewise. * tests/readlink/can-e: Likewise. * tests/readlink/can-f: Likewise. * tests/readlink/can-m: Likewise. * tests/rm/inaccessible: Likewise. * tests/rm/unread3: Likewise. * tests/touch/no-create-missing: Likewise. * lib/.cvsignore: Add uinttostr.c.

# Show that fts (hence du, chmod, chgrp, chown) fails when all of the
|
|
# following are true:
|
|
# - `.' is not readable
|
|
# - operating on a hierarchy containing a relative name longer than PATH_MAX
|
|
# - run on a system where gnulib's openat emulation must resort to using
|
|
# save_cwd and restore_cwd (which fail if `.' is not readable).
|
|
# Thus, the following du invocation should succeed on newer Linux and
|
|
# Solaris systems, yet it must fail on systems lacking both openat and
|
|
# /proc support. However, before coreutils-6.0 this test would fail even
|
|
# on Linux+PROC_FS systems because its fts implementation would revert
|
|
# unnecessarily to using FTS_NOCHDIR mode in this corner case.
