Run "make update-copyright" and then...
* gnulib: Update to latest with copyright year adjusted.
* tests/init.sh: Sync with gnulib to pick up copyright year.
* bootstrap: Likewise.
* tests/sample-test: Adjust to use the single most recent year.

Many tests use `program ... && fail=1` to ensure expected
error situations are indicated. However that would mask
an unexpected exit (like a crash). Therefore explicitly
check the expected exit code.
Note where error messages are also verified, the extra
protection is not added.
* tests/init.sh (returns_): A new helper function to
check the return code of a command, and used
throughout the tests.
* cfg.mk (sc_prohibit_and_fail_1): Add a syntax check
to avoid new instances of this issue.

Run "make update-copyright" and then...
* tests/sample-test: Adjust to use the single most recent year.
* tests/du/bind-mount-dir-cycle-v2.sh: Fix case in copyright message,
so that year is updated automatically in future.

* HACKING: GID is more useful in tests than group name, so rename
input param from NON_ROOT_GROUP to NON_ROOT_GID to make it obvious
that only a group ID is now acceptable, thus allowing GID lookups
to be avoided throughout the tests.
* init.cfg (require_root_): Likewise.
* tests/misc/truncate-owned-by-other.sh: Avoid looking up the GID.
* tests/touch/now-owned-by-other.sh: Likewise.
* tests/misc/chroot-credentials.sh: Likewise. Also fix an instance
of comparison against NON_ROOT_GROUP which would have given a false
failure if a non numeric value was passed in.
* tests/id/setgid.sh: Use previously looked up gid as a more
accurate base for the subsequent adjustment, and move
the uid lookup within chroot, rather than having the overhead
of a separate `id` invocation.

It's dangerous and confusing to leave root's supplemental
groups in place when specifying other users with --userspec.
In the edge case that that is desired one can explicitly
specify --groups.
Also we implicitly set the system defined supplemental groups
for a user. The existing mechanism where supplemental groups
needed to be explicitly specified is confusing and not general
when the lookup needs to be done within the chroot.
Also we extend the --groups syntax slightly to allow clearing
the set of supplementary groups using --groups=''.
* src/chroot.c (setgroups): On systems without supplemental groups,
clearing then is a noop and so should return success.
(main): Lookup the primary GID with getpwuid() when just a numeric
uid is specified, and also infer the USERNAME from this call,
needed when we're later looking up the supplemental groups for a user.
Support clearing supplemental groups, either implicitly for
unknown users, or explicitly when --groups='' is specified.
* tests/misc/chroot-credentials.sh: Various new test cases
* doc/coreutils.texi (chroot invocation): Adjust for the new behavior.
* NEWS: Mention the change in behavior.

- Support arbitrary numbers in --groups, consistent with
what is already done for --userspec
- Avoid look-ups entirely for --groups items with a leading '+'
- Support names that are actually numbers in --groups
- Ignore an empty --groups="" option for consistency with --userspec
- Look up both inside and outside the chroot with inside taking
precedence. The look-up outside may load required libraries
to complete the look-up inside the chroot. This can happen for
example with a 32 bit chroot on a 64 bit system, where the
32 bit NSS plugins within the chroot fail to load.
* src/chroot.c (parse_additional_groups): A new function refactored
from set_addition_groups(), to just do the parsing. The actual
setgroups() call is separated out for calling from the chroot later.
(main): Call parse_user_spec() and parse_additional_groups()
both outside and inside the chroot for the reasons outlined above.
* tests/misc/chroot-credentials.sh: Ensure arbitrary numeric IDs
can be specified without causing look-up errors.
* NEWS: Mention the improvements.
* THANKS.in: Add Norihiro Kamae who initially reported the issue
with a proposed patch.
Also thanks to Dmitry V. Levin for his diagnosis and sample patch.

Run "make update-copyright", but then also run this,
perl -pi -e 's/2\d\d\d-//' tests/sample-test
to make that one script use the single most recent year number.
|
|
* tests/misc/chroot-credentials.sh: Don't assume uid 0
has the "root" name, nor any name for that matter.

* Makefile.am (SUBDIRS): Remove 'tests'.
(include): The '$(top_srcdir)/tests/local.mk' file.
(check-root): Remove this convenience target, it's no longer needed
now that the "real" check-root target once in 'tests/Makefile' will
land in the top-level makefile.
* configure.ac (AC_CONFIG_FILES): Remove 'tests/Makefile'.
* tests/Makefile.am: Rename ...
* tests/local.mk: ... like this, with a lot of adjustments.
* tests/init.cfg: Move ...
* init.cfg: ... here. This is necessary, for a limitation of the
gnulib-provided 'tests/init.sh', which unconditionally look for
'init.cfg' in the $(srcdir) directory.
* tests/*/*.sh: Adjust: expect init.sh to be in '$srcdir/tests',
not in '$srcdir', and extend $PATH with './src', not with '../src'.
* tests/Coreutils.pm: Adjust similarly.
* tests/pr/pr-tests.pl ($pfx): Likewise.

Not only this shrinks the size of the generated Makefile (from > 6300
lines to ~3000), but will allow further simplifications in future
changes.
* tests/Makefile.am (TEST_EXTENSIONS): Add '.sh' and '.pl'.
(PL_LOG_COMPILER, SH_LOG_COMPILER): New, still defined simply to
$(LOG_COMPILER) for the time being.
(TESTS, root_tests): Adjust as described.
* All tests: Rename as described.
