* tests/misc/sync.sh: Normalize the error messages
when syncing a non read/write directory, as AIX
gives the "Is a directory" error.
Also ensure that sync(1) returns an error for this
case on all systems.
Most programs take care to operate on all command-line-specified
operands before exiting. That is an important feature that allows
to identify all problems with the first run. However, groups would
exit upon the first problematic user name.
Bug introduced via commit v6.10-56-g167b8025ac.
* src/groups.c (main): Do not exit immediately upon error.
* tests/misc/groups-process-all.sh: New file. Test for this.
* tests/local.mk (all_tests): Add it.
* NEWS (Bug fixes): Mention this.
* tests/misc/groups-dash.sh: Avoid false failure on a system for which
"none" is a valid user name. The first invocation would succeed, and
the second would fail with "groups: ‘--’: no such user".
Use a user name that cannot exist.
Discussed in https://bugs.gnu.org/26779 .
* NEWS: Mention the improvement.
* bootstrap.conf: Add gnulib modules mbslen,mbschr.
* src/expr.c (mbs_logical_substr): New function to return a substring
based on logical character positions (instead of bytes).
(mbs_logical_cspn): Similar to strcspn/mbscspn, but returns number of
logical characters instead of byte offset.
(mbs_offset_to_chars): New function to return number of logical
characters fitting in a given byte offset.
(docolon): Report matched logical characters instead of bytes.
(eval6): For length/substr/index operations, use logical characters
instead of bytes by calling the above new functions.
* tests/misc/expr.pl: Repeat all tests with non-C locale to detect any
regressions.
* tests/misc/expr-multibyte.pl: New tests with multibyte input.
* tests/local.mk: Add new test file.
Add a test for CVE-2017-7476 which was fixed in gnulib at:
http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=commitdiff;h=94e01571
* tests/misc/date-tz.sh: Add a new test which overwrites enough
of the heap to trigger a segfault, even without ASAN enabled.
* tests/local.mk: Reference the new test.
* NEWS: Mention the bug fix.
* doc/coreutils.texi (Options for date): Capitalize a sentence.
* tests/misc/date-debug.sh: Adjust --debug output to match
recent changes to Gnulib’s parse-datetime module.
* src/shred.c (fillpattern): Fix the "off by one" issue when
testing whether we have enough space to copy the already
written portion of the buffer to the remainder of the buffer.
Specifically for buffer sizes that are (3*(2^x))+1, i.e. 7,13,...
we both use an uninitialized byte and invoke undefined
behavior in memcpy() operation on overlapping memory regions.
* tests/misc/shred-passes.sh: Add an invocation that will
trigger either valgrind UMR, or ASAN like:
ERROR: AddressSanitizer: memcpy-param-overlap: memory ranges
#1 0x403065 in fillpattern src/shred.c:293
A direct test is awkward due to the random writes surrounding
the problematic pattern writes.

On some platforms, isatty succeeds but ttyname fails.
POSIX does not seem to allow this, but there it is.
Problem reported by Christian Brauner (Bug#26371).
While we’re at it, check for errors more carefully and return a
new exit status 4 if stdin is closed or a similar error occurs.
* doc/coreutils.texi (tty invocation): Document new behavior.
* init.cfg (stderr_fileno_):
Don't assume have_input_tty is not in the environment.
* src/tty.c (TTY_STDIN_ERROR): New constant.
(main): Exit with nonzero status if there is a usage error,
like other coreutils programs.
Check for error in getting stdin type.
* tests/misc/tty.sh: New file.
* tests/local.mk (all_tests): Add it.
Support --tabs="1,+8" which is equivalent to --tabs="1,9,17,..."
useful for viewing unified diff output with its 1 character
gutter for example.
* doc/coreutils.texi ({expand,unexpand} invocation): Document,
using diff processing as the example.
* src/expand-common.c (set_increment_size): Update the new
increment_size global.

(finalize_tab_stops): Verify both '+' and '/' prefixes
are not used together.
* tests/misc/expand.pl: Add test cases.
* NEWS: Mention the new feature.
* tests/misc/cut-huge-range.sh: On some systems returns_ may
use more memory, so incorporate that in the determination
of the ulimit value to use. Noticed on ARMv7 with bash-4.4.12,
and x86_64 with bash-4.2.37.

* tests/misc/md5sum-bsd.sh: Add a test case.
* NEWS: Mention the bug fix.
Fixes http://bugs.gnu.org/26263
* tests/misc/sort-debug-keys.sh: Disparate LC_CTYPE and LC_MESSAGES
are not supported, with the result LC_MESSAGES=C is used throughout.
Therefore just set LC_ALL in the test, and normalize the message
variants with sed.
Reported and tested by J Rogowsky.
* doc/coreutils.texi (expand invocation): Document the feature.
(unexpand invocation): Likewise.
* src/expand-common.c (extend_size): A new global to use
when the last tab stop is prefixed by '/'.
(set_extend_size): A new function to validate and set
the new extend_size global.
(parse_tab_stops): Call set_extend_size() for '/' prefixes.
(finalize_tab_stops): Ensure a single specified '/' is
treated like a standard tabsize, but also ensure that
when '/' is specified with a single other entry that
we process as a list rather than a tab size.
(get_next_tab_stop): Use the tab size if set,
for items after the user specified tab position list.
* tests/misc/expand.pl: Add test cases
* NEWS: Mention the new feature.

This comes from the latest gnulib.
Also handling of OMP_NUM_THREADS has been adjusted
to support comma separated values indicating a nesting level,
in which case the first value is taken. Also OMP_NUM_THREADS=0
is now ignored instead of being treated as 1, to match
the behavior of libgomp.
* NEWS: Mention the OMP_THREAD_LIMIT improvement,
and OMP_NUM_THREADS now handling nested values.
* doc/coreutils.texi (nproc invocation): Describe OMP_THREAD_LIMIT
as a way to set the max value, with OMP_THREAD_LIMIT setting the min.
* tests/misc/nproc-override.sh: A new test to exercise the
updated gnulib code with all combinations of these OMP variables.
* tests/local.mk: Reference the new test.
Problem reported by Paul Wise for Debian, in:

This is fallout from the fix for GNU Bug#23035.
* src/date.c (batch_convert): New args TZ and TZSTRING.
All uses changed.
(batch_convert, main): Adjust to parse_datetime2 API change.
(main): Allocate time zone object.
* tests/misc/date-debug.sh: Fix incorrect test case,
caught by the fix.
* tests/misc/date.pl: Test the fix.
A lot of this is converting http: to https:.
Also, gmane went away, so remove URLs that no longer work and
are not easy to figure out what they were.
Some of this stuff is so old that it no longer matters anyway.
* src/stty.c (apply_settings): A new function refactored
from main() that is used to both check and apply options.
(main): Call apply_settings before we open the device,
so all validation is done before interacting with a device.
* NEWS: Mention the improvement.
* tests/misc/stty.sh: Add a test case.
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.
* src/wc.c (wc): Avoid reading the end of the file
when the size is not a multiple of PAGE_SIZE,
as the special case handling for files in /proc and /sys
is only required when st_size is 0 or a multiple of PAGE_SIZE.
* tests/misc/wc-proc.sh: Add a test case.
While st_size would have been incorrect for subsequent
files since v7.1, it was only used since v8.24.
* tests/misc/wc-files0.sh: s/7.1/8.24/
* NEWS: Likewise.
Reported by Bernhard Voelker
* src/wc.c (main): Reset fstatus[0].failed between files when reusing
the fstatus[0] entry in --files-from0 mode. This ensures a stat() is
done for each file, avoiding incorrect counts and redundant reading.
* NEWS: Mention the bug fix.
* tests/misc/wc-files0.sh: Add a test case.

When running "make check" on a Linux system running SELinux with a
non-MLS policy, tests/mkdir/restorecon.sh test fails with:
chcon: invalid context: root:object_r:tmp_t:s0: Invalid argument
Indeed in such a configuration, contexts cannot have ":s0" suffix.
* init.cfg (get_selinux_type): Refactor this function to here
from various tests. Update to work with a non-MLS policy.
(mls_enabled_): A new function to detect if MLS is enabled.
(skip_if_mcstransd_is_running_): Update to not skip when
MLS is not enabled.

* tests/install/install-Z-selinux.sh: Likewise.
* tests/cp/cp-a-selinux.sh: Likewise.
* tests/misc/selinux.sh: Likewise.

the variances in sterror output.
* tests/rm/rm-readdir-fail.sh: Likewise. Also avoid ERRORs
on systems that don't define _D_EXACT_NAMELEN.
This was detected with ASAN, but can also be seen without ASAN with:
$ tac - - <&-
tac: standard input: read error: Bad file descriptor
*** Error in `tac': malloc(): memory corruption: 0x...
* src/tac.c (copy_to_temp): Don't close our output stream on
(possibly transient) output error, or on input error.
(temp_stream): clearerr() on the stream about to be reused,
to ensure future stream use is not impacted by transient errors.

Note we don't support the --algorithm option of the
b2sum command in the external BLAKE2 project, as that

The old code mishandled --time-spec='+%%b', as it misinterpreted
the '%b' as being the month abbreviation. Also, it mishandled
the extremely unlikely case of a month abbreviation containing '%'.
The performance part of this patch sped up 'ls' by about 1% on my
little benchmark of 'ls -lR' on the source directory in the
en_US.UTF-8 locale (Fedora 24 x86-64).
* NEWS: Document the bug fix.
* src/ls.c (first_percent_b, abformat_init): New static functions.
(ABFORMAT_SIZE): New constant.
(use_abformat): New static var.
(abmon, required_mon_width): Remove these static vars.
(abmon_init): Now accepts a pointer to abmon, and returns a boolean.
All callers changed. Reject month abbrs containing '%', as these
would mess up strftime. Simplify mbsalign result checking,
since (size_t) -1 exceeds ABFORMAT_SIZE.
(abformat_init, align_nstrftime): Precompute all 24 formats at
startup, rather than computing a format for each time stamp.
(decode_switches): Call abformat_init instead of abmon_init.
(align_nstrftime): Accept recentness bool instead of format.
All callers changed.

next_file): Move identical functions to new module.
(add_tab_stop): Move to new module, including additional code from
'unexpand' (keeping max_column_width) which will have no effect in when
used in 'expand'. Refactor common next-column calculation code
into a new function 'get_next_tab_column'.
* src/local.mk: (src_expand_SOURCES, src_unexpand_SOURCES): Add
