* tests/test-lib.sh (Exit): New function by Ralf Wildenhues in automake http://git.sv.gnu.org/gitweb/?p=automake.git;a=commitdiff;h=20594c08f63 * tests/**: Convert all uses: This restrictive change converted the vast majority: git grep -l '^(exit \$fail); exit \$fail$' \ | xargs perl -pi -e 's/'^\(exit \$fail\); exit \$fail$/Exit \$fail/' And this did the rest, plus a few undesirable ones, so I manually backed out the changes to ChangeLog-* and build-aux/check.mk: git grep -l -E '\(exit [^)]+\); exit ' \ | xargs perl -pi -e 's/\(exit (.+?)\); exit \1/Exit $1/'

# 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.
