+
+	version 9.4
+	* NEWS: Record release date.
+
+2023-08-28  Paul Eggert  <eggert@cs.ucla.edu>
+
+	maint: spelling fixes, including author names
+	Most of this just affects commentary and documentations.  The only
+	significant behavior change is translating author names via
+	proper_name_lite rather than proper_name_utf8, or not translating
+	them at all.  proper_name_lite is good enough for coreutils and
+	avoids the bloat that had coreutils not using Gnulib proper_name.
+	* bootstrap.conf (gnulib_modules): Use propername-lite instead
+	of propername.
+	(XGETTEXT_OPTIONS): Look for proper_name_lite instead of for
+	proper_name_utf8.
+	* cfg.mk (local-checks-to-skip): Remove
+	sc_proper_name_utf8_requires_ICONV, since we no longer use
+	proper_name_utf8.
+	(old_NEWS_hash): Update.
+	(sc_check-I18N-AUTHORS): Remove; no longer needed.
+
+	test: omit unreachable code
+	* src/test.c (unary_operator): Omit unreachable ‘return false;’.
+	Oracle Solaris Studio 12.6 warns about it.
+
+2023-08-28  Bruno Haible  <bruno@clisp.org>
+
+	tests: avoid test failure on Android
+	* gl/tests/test-mbsalign.c (main): Skip the unibyte truncation test
+	on Android, when the "C" locale in fact is multibyte.
+
+2023-08-28  Paul Eggert  <eggert@cs.ucla.edu>
+
+	sort: port sort-merge-fdlimit test to Solaris 10
+	* tests/sort/sort-merge-fdlimit.sh: Give 'sort' fd 6 too.
+	Needed for the same reason sort-continue.sh needed a ulimit -n boost.
+
+	sort: port sort-continue test back to Solaris 10
+	* tests/sort/sort-continue.sh: Use ulimit -n 7 not -n 6.  On
+	Solaris 10 'sort' uses Gnulib mkostemp, which calls Gnulib
+	getrandom, which opens /dev/urandom to calculate the temp file's
+	name, which means 'sort' needs one more file descriptor to work.
+
+2023-08-27  Pádraig Brady  <P@draigBrady.com>
+
+	tests: avoid false failure on cygwin
+	* tests/cksum/md5sum-bsd.sh: Avoid part of test dealing with backslashes
+	in file names, on systems where backslash is a directory separator.
+	Issue reported by Bruno Haible on cygwin.
+
+2023-08-27  Pádraig Brady  <P@draigBrady.com>
+
+	cksum: adjust tests and docs to binary mode handling
+	Following commit v9.3-80-g5e1e0993b which makes cksum
+	match the output of the standalone utilities...
+
+	* doc/coreutils.texi (cksum output modes): Remove the mention
+	that cksum never outputs a binary indicator, as that's no longer the
+	case.
+	* tests/cksum/b2sum.sh: Avoid outputting a binary indicator.
+	* tests/cksum/sm3sum.pl: Likewise.
+
+2023-08-27  Pádraig Brady  <P@draigBrady.com>
+
+	all: avoid duplicated write errors on FreeBSD
+	* src/system.h (write_error): Also call fpurge(), which was seen to
+	be needed on FreeBSD 13.1 to avoid duplicated write errors.
+	* src/head.c (xwrite_stdout): Likewise.
+	* bootstrap.conf: Depend on fpurge.
+	Reported by Bruno Haible.
+
+	tests: avoid false failure where sleep is a shell builtin
+	* tests/misc/usage_vs_getopt.sh: Handle sleep as a shell builtin,
+	which was seen on Alpine Linux 3.18.
+
+2023-08-27  Bruno Haible  <bruno@clisp.org>
+
+	build: fix link errors of sort, split on CentOS 5 and Solaris 10
+	* src/local.mk (src_sort_LDADD, src_split_LDADD): Add $(CLOCK_TIME_LIB).
+
+	build: fix compilation error on AIX 7.1
+	* src/copy.c (copy_internal): Don't test for ENOTEMPTY if it has the
+	same value as EEXIST.
+
+2023-08-27  Pádraig Brady  <P@draigBrady.com>
+
+	build: update with gnulib fixes
+	* gnulib: Update to incorporate gnulib fixes
+	from Bruno Haible from his coreutils 9.4 pre-release testing.
+
+2023-08-24  Pádraig Brady  <P@draigBrady.com>
+
+	doc: remove older ChangeLog items
+	* Makefile.am: Update the oldest documented version
+	to 8.30 which is now about 5 years old.
+
+2023-08-23  Pádraig Brady  <P@draigBrady.com>
+
+	shred: fix operation on Solaris with 64 bit builds
+	* NEWS: Mention the bug fix.
+	* gl/lib/randread.c (get_nonce): Limit getrandom() <= 1024 bytes.
+
+2023-08-22  Pádraig Brady  <P@draigBrady.com>
+
+	build: update gnulib submodule to latest
+	* gnulib: Update to latest
+
+	doc: reorg texinfo for the checksumming utilities
+	* doc/coreutils.texi: Reorg so that 'cksum invocation' is the
+	main node listing all options and output formats, which is then
+	referenced by the descriptions of the standalone utilities.
+	Use macros in the description of the standalone utilities
+	rather than referencing 'md5sum invocation' to be more direct.
+
+2023-08-21  Pádraig Brady  <P@draigBrady.com>
+
+	doc: cksum: remove -b description from texinfo
+	* doc/coreutils.texi (cksum invocation): Following commit 5e1e0993
+	also remove the desciption of the -b option for the cksum command.
+
+	cp: with --sparse=never, avoid COW and copy offload

+
+	uptime: simplify following gnulib changes
+	* build-aux/gen-lists-of-programs.sh (build_if_possible_progs):
+	Remove uptime.
+	(normal_progs): Add uptime.
+	* configure.ac: Remove GNULIB_BOOT_TIME invocation.
+	* m4/boottime.m4: Remove file.
+	* src/uptime.c: Don't include <sys/sysctl.h>, <OS.h>.
+	(print_uptime): Don't call sysctl, get_system_info, as Gnulib's
+	readutmp module now does this.
+
+2023-08-15  Paul Eggert  <eggert@cs.ucla.edu>
+
+	maint: update uptime NEWS
+	* NEWS: Update as per Bruno Haible <https://bugs.gnu.org/65255#14>.
+
+2023-08-15  Pádraig Brady  <P@draigBrady.com>
+
+	tests: fix false failure due to locale on alpine
+	* tests/sort/sort-debug-keys.sh: Decimal point was seen to be '.'
+	on fr_FR.UTF-8 on Alpine Linux 3.18, so add an extra guard
+	to ensure we've a ',' as the decimal point on this locale.
+	Fixes https://bugs.gnu.org/65310
+
+2023-08-15  Paul Eggert  <eggert@cs.ucla.edu>
+
+	uptime: be more generous about read_utmp failure
+	* src/uptime.c (print_uptime): Check for overflow
+	when computing uptime.  Use C99-style decl after statements.
+	Do not let an idx_t value go negative.
+	(print_uptime, uptime): Be more generous about read_utmp failures,
+	or when read_utmp does not report the boot time.  Instead of
+	failing, warn but keep going, printing the information that we did
+	get, and then exit with nonzero status.
+	(print_uptime): Return the desired exit status.  Caller changed.
+
+2023-08-15  Bruno Haible  <bruno@clisp.org>
+
+	uptime: Include VM sleep time in the "up" duration
+	* src/uptime.c: Don't include c-strtod.h.
+	(print_uptime): Don't read /proc/uptime, because the value it provides
+	does not change when a date adjustment occurs.
+	* bootstrap.conf (gnulib_modules): Remove 'uptime'.
+
+2023-08-15  Paul Eggert  <eggert@cs.ucla.edu>
+
+	build: update gnulib submodule to latest
+
+2023-08-15  Bernhard Voelker  <mail@bernhard-voelker.de>
+
+	maint: fix typo in NEWS
+	* NEWS: s|/who/log/wtmp|/var/log/tmp|, introduced in commit 85edb4afbd1.
+
+2023-08-15  Bernhard Voelker  <mail@bernhard-voelker.de>
+
+	doc: reference install(1) and cp(1) from each other
+	* man/cp.x (SEE ALSO): Add install(1).
+	* man/install.x (SEE ALSO): Add cp(1).
+
+	Discussed at
+	https://lists.gnu.org/r/coreutils/2023-08/msg00026.html
+
+2023-08-14  Bruno Haible  <bruno@clisp.org>
+
+	build: fix recent compilation error on GNU/Hurd
+	* src/copy.c (set_author): Revert change from MACH_PORT_NULL to
+	MACH_PORT_nullptr from commit 16b5ca6e (2023-06-29).
+
+2023-08-14  Pádraig Brady  <P@draigBrady.com>
+
+	maint: avoid syntax-check failure
+	* po/POTFILES.in: Cater to lib/file-type.c adjustments
+	as suggested by sc_po_check.
+
+2023-08-14  Bruno Haible  <bruno@clisp.org>
+
+	build: fix link errors with gcc < 4.8
+	* configure.ac: Attempt to link, not only compile, the test programs
+	with __builtin_cpu_supports, to avoid link errors with cksum and wc.
+
+2023-08-13  Paul Eggert  <eggert@cs.ucla.edu>
+
+	doc: improve NEWS discussion of systemd
+
+	build: update gnulib submodule to latest
+
+2023-08-12  Pádraig Brady  <P@draigBrady.com>
+
+	maint: allow use of printf C99 integer size specifiers
+	Older systems that had issues with these like HP-UX and Solaris 8
+	are now obsolete, and can easily apply patches to provide support.
+	Also we've used %td since coreutils 9.1, with no reported issues.
+
+	* cfg.mk (sc_prohibit-c99-printf-format): Remove to allow use of
+	%[jtz] size specifiers, which allows for cleaner code
+	by avoiding the need to cast to PRI?MAX etc.
+
+2023-08-11  Pádraig Brady  <P@draigBrady.com>
+
+	doc: separate out description of 2038 time stamp change
+	* NEWS: Separate out the description of the _existing_ issues
+	with outputting timestamps on 32 bit systems, from _future_ issues
+	outputting timestamps on all systems.  Also move this to the
+	"improvement" section, since it's not really a coreutils
+	specific issue, and also is a build time configurable option.
+
+2023-08-11  Bruno Haible  <bruno@clisp.org>
+
+	pinky,users,who: optimize read_utmp invocation
+	When we are only interested in entries of type USER_PROCESS, tell
+	read_utmp that it does not need to determine the boot time.
+
+	* src/pinky.c (short_pinky): Pass option READ_UTMP_USER_PROCESS.
+	* src/users.c (users): Likewise.
+	* src/who.c (who): Likewise, if calling list_entries_who.
+
+2023-08-09  Paul Eggert  <eggert@cs.ucla.edu>
+
+	who: simplify based on readutmp changes
+	* src/pinky.c (time_string, print_entry, scan_entries, short_pinky):
+	* src/uptime.c (print_uptime, uptime):
+	* src/users.c (list_entries_users, users):
+	* src/who.c (UT_TYPE_RUN_LVL, UT_TYPE_INIT_PROCESS)
+	(UT_TYPE_LOGIN_PROCESS, UT_TYPE_DEAD_PROCESS, UT_TYPE_NEW_TIME)
+	(time_string, print_user, print_boottime)
+	(make_id_equals_comment, print_deadprocs, print_login)
+	(print_initspawn, print_clockchange, print_runlevel)
+	(list_entries_who, scan_entries, who):
+	Simplify, partly by using plain -> rather than macros.
+
+	pinky,who: omit pragma
+	* src/pinky.c, src/who.c:
+	Omit no-longer-needed -Wstringop-overread pragma.
+
+2023-08-09  Bruno Haible  <bruno@clisp.org>
+
+	maint: Simplify after gnulib changed
+	Update gnulib submodule to latest.
+	All of UT_USER_SIZE, UT_ID_SIZE, UT_LINE_SIZE, UT_HOST_SIZE are now -1.
+
+	* src/pinky.c (print_entry): Remove code for bounded-length ut_line,
+	ut_user, ut_host.
+	(scan_entries): Remove code for bounded-length ut_user.
+	* src/who.c (print_line): Remove userlen, linelen arguments.
+	(print_user): Remove code for bounded-length ut_line, ut_user, ut_host.
+	(make_id_equals_comment): Remove code for bounded-length ut_id.
+	(print_boottime, print_deadprocs, print_login, print_initspawn,
+	print_clockchange, print_runlevel, print_heading): Update print_line
+	invocations.
+	(scan_entries): Remove code for bounded-length ut_line.
+
+2023-08-04  Paul Eggert  <eggert@cs.ucla.edu>
+
+	maint: Update after gnulib module 'readutmp' changed
+	(This patch is coauthored with Bruno Haible,
+	with original version at <https://bugs.gnu.org/64937#>.)
+	This updates the gnulib submodule to latest.
+	For year-2038 safety on Linux/{x86,arm},
+	this adds an --enable-systemd option to ‘configure’.
+	The idea is that this sort of thing will become the default
+	after it has been tested more.
+	* configure.ac: Don't test whether struct utmp and struct utmpx
+	have the ut_host field; this is now done in gnulib's readutmp module.
+	* src/local.mk: Link the programs 'pinky', 'uptime', 'users',
+	'who' with $(READUTMP_LIB).
+	* src/pinky.c, src/who.c:
+	Test HAVE_STRUCT_XTMP_UT_HOST instead of HAVE_UT_HOST.
+	* src/pinky.c (print_entry):
+	* src/who.c (print_user, print_deadprocs, print_login)
+	(print_initspawn, scan_entries):
+	Support the situation where ut_line is a 'char *' rather than a
+	'char[]' of fixed size.  Likewise for ut_user and ut_host.
+	(make_id_equals_comment): Likewise for ut_id.
+	* src/pinky.c (print_entry):
+	* src/who.c (print_user):
+	Open /dev to simplify looking up its entries.
+	Don’t use printf if the output might in theory be longer than INT_MAX.
+	* src/pinky.c (scan_entries, short_pinky):
+	* src/uptime.c (print_uptime, uptime):
+	* src/users.c (list_entries_users, users):
+	* src/who.c (who):
+	Use idx_t where new read_utmp needs it.
+	* src/system.h (STREQ_LEN): Add comment that last arg can be -1.
+
+2023-08-02  Paul Eggert  <eggert@cs.ucla.edu>
+
+	uptime: fix Y5881633 bug
+	* src/uptime.c (print_uptime): Prefer signed types.
+	Fix unlikely bug on platforms with 32-bit long and 64-bit time_t
+	if the idle time exceeds 2**31 days (about 6 million years...).
+
+	pinky: fix "d" typo
+	Problem reported by Bruno Haible (bug#65003).
+	* src/pinky.c (idle_string): Fix recently-introduced typo:
+	missing "d" for "days".
+
+2023-08-01  Dragan Simic  <dsimic@manjaro.org>
+
+	maint: minor comment cleanups
+	* src/cut.c: Adjust a few comments slightly, simply to have their
+	trailing whitespace the same as in the majority of the comments.
+
+	cut: promptly diagnose write errors, continued
+	* src/cut.c: Complete the error-handling improvements started in
+	commit e0a4a60af5, by adding a couple of remaining checks for putchar().
+	While there, sprinkle a few rather useful comments, and perform a few
+	small code cleanups, to make the code and the comments more uniform
+	and more conformant to the official coding style.  Also make the help
+	message slightly more uniform.
+
+	maint: reformat text width in HACKING
+	* HACKING: Adjust line lengths.
+
+2023-08-01  Pádraig Brady  <P@draigBrady.com>
+
+	pinky: fix buffer size on 32 bit builds
+	* src/pinky.c (idle_string): Use the correct buffer size
+	following the recent int type adjustment.
+
+	od: fix issues with recent format string changes
+	* src/ioblksize.h: Avoid syntax check with redundant idx.h inclusion.
+	* src/od.c (FMT_BYTES_ALLOCATED): Increase by two to avoid:
+	  error: '%s' directive writing between 1 and 2 bytes into a region
+	  of size between 1 and 4 [-Werror=format-overflow=]
+	(maint): Use %td to print idx_t rather than invalid %jt format.
+
+2023-08-01  Paul Eggert  <eggert@cs.ucla.edu>
+
+	pinky: prefer signed types
+	* src/pinky.c (idle_string): Prefer intmax_t to unsigned long int;
+	this avoids an overflow on platforms where unsigned long is 32
+	bits and time_t is 64 bits (the bug could occur on such a system
+	that was idle for more than 6 million years, so it’s a bit
+	hard to supply a test case...).
+
+	pathchk: prefer signed types
+	* src/pathchk.c (validate_file_name): Prefer signed types.
+
+	numfmt: prefer signed types
+	* src/numfmt.c (suffix_power_char, powerld, expld)
+	(simple_strtod_int, double_to_human, prepare_padded_number)
+	(process_suffixed_number): Prefer signed types.
+	(process_suffixed_number): Fix an unlikely bug if an
+	arg has exactly 2**32 spaces at the start.
+
+	mktemp,seq: prefer signed types
+	* src/mktemp.c (main):
+	* src/seq.c (main): Prefer signed types.
+
+	kill: prefer signed types
+	* src/kill.c (list_signals):
+	Prefer signed types.  This avoids undefined behavior on
+	theoretical platforms where unsigned and signed int have
+	different representations.
+
+	groups,id: don’t assume gid_t fits in unsigned long
+	* src/group-list.c (print_group): Convert to intmax_t or
+	uintmax_t, not to unsigned long.
+
+	dircolors,du,expr: prefer signed types
+	* src/dircolors.c (dc_parse_stream):
+	* src/du.c (max_depth, main):
+	* src/expr.c (main):
+	Prefer signed types.
+
+	od: prefer signed types
+	* src/od.c: Include stdckdint.h.
+	(bytes_to_oct_digits, bytes_to_signed_dec_digits)
+	(bytes_to_unsigned_dec_digits, bytes_to_hex_digits):
+	Use ‘char’ for these small constants.
+	(simple_strtoi): Rename from simple_strtoul.  Convert to int
+	instead of unsigned long; that’s good enough.  All uses changed.
+	Simplify by using ckd_mul and ckd_add to check for overflow.
+	(main): Prefer signed types to unsigned.
+
+	cksum,df,digest: prefer signed types
+	* src/cksum.c (main):
+	* src/df.c (decode_output_arg):
+	* src/digest.c (valid_digits):
+	Prefer idx_t to unsigned types when the value is an index
+	into an array.
+
+	join: prefer signed types
+	* src/join.c (struct outlist, struct field, struct line)
+	(struct seq, autocount_1, autocount_2, join_field_1, join_field_2)
+	(extract_field, keycmp, check_order, init_linep, free_spareline)
+	(getseq, delseq, prfield, prfields, prjoin, join, add_field)
+	(string_to_join_field, decode_field_spec, add_field_list)
+	(set_join_field, main):
+	Prefer signed integers to unsigned.
+
+	factor: prefer signed types
+	When it’s easy, prefer signed types to unsigned, as
+	they are less confusing and allow overflow checking.
+	* src/factor.c (struct mp_factors, udiv_qrnnd)
+	(count_leading_zeros, count_trailing_zeros)
+	(factor_insert_multiplicity, mp_factor_clear, mp_factor_insert)
+	(factor_insert_refind, factor_using_division)
+	(mp_factor_using_division, powm2, millerrabin, millerrabin2)
+	(mp_millerrabin, prime_p, prime2_p, mp_prime_p, isqrt, isqrt2)
+	(invtab, q_freq, factor_using_squfof, strto2uintmax)
+	(print_factors_single, main):
+	Prefer signed integers to unsigned.
+
+	maint: include idx.h everywhere
+	* src/system.h: Include idx.h here, instead of in every file
+	that currently uses idx_t.  This should make it easier to use
+	idx_t in the future.
+
+2023-07-31  Paul Eggert  <eggert@cs.ucla.edu>
+
+	who: fix only-theoretical overflow
+	Change stzncpy’s implementation to match its comment, in the case
+	where SRC + LEN would overflow.  This case never happens in coreutils.
+	* src/system.h (stzncpy): Work even if SRC + LEN would overflow.
+

+
+	tac: handle short reads on input
+	This can be reproduced by getting the read() above 2G,
+	which induces a short read, thus triggering the erroneous failure.
+
+	  $ truncate -s 5G 5G
+
+	  $ cat 5G | TMPDIR=$PWD tac | wc -c
+	  tac: /tmp/tacFt7txA: read error: Illegal seek
+	  0
+
+	With the fix in place we now get:
+
+	  $ cat 5G | TMPDIR=$PWD src/tac | wc -c
+	  5368709120
+
+	* src/tac.c (tac_seekable): Use full_read() to handle short reads.
+	* NEWS: Mention the bug fix.
+	Reported at https://bugs.debian.org/1042546
+
+2023-07-31  Bruno Haible  <bruno@clisp.org>
+
+	uptime: output correct user count on OpenBSD
+	* src/uptime.c (print_uptime, uptime): Always call read_utmp
+	and count the result.
+	* NEWS: Mention the fix (text by Bruno Haible).

+
+	mv: better diagnostic for 'mv dir x' failure
+	Problem reported by Nir Oren <https://bugs.gnu.org/64785>.
+	* src/copy.c (copy_internal): Use a more-specific diagnostic when
+	a rename fails due to a problem that must be due to the
+	destination, avoiding user confusion in cases like 'mv dir x'
+	where x is a nonempty directory.
+	* tests/mv/dir2dir.sh: Adjust to match.
+
+2023-07-20  Pádraig Brady  <P@draigBrady.com>
+
+	doc: clarify tail -n/-c +NUM operation
+	tail -n/-c +NUM, is different from tail -n/-c NUM,
+	and head -n/-c NUM, and head -n/c -NUM, in that it
+	specifies a 1 based index rather than a count to skip/include.
+	So clarify this in tail --help and tail info manual.
+	Note we also mention this gotcha at:
+	https://www.pixelbeat.org/docs/coreutils-gotchas.html#tail
+
+	* doc/coreutils.texi (tail invocation): Give examples for -c/-n +NUM,
+	to make it clear one has to specify a number 1 larger than
+	might be expected.
+	* src/tail.c (usage): State the skip at start edge case more clearly
+	in the -n description. -c is not often used with tail so we leave
+	full explanation of that to the info manual.  Also split the string
+	to simplify translation.
+

+	tee: support non blocking outputs
+	Non blocking outputs can be seen for example
+	when piping telnet through tee to a terminal.
+	In that case telnet sets its input to nonblocking mode,

+	in which case in may receive an EAGAIN error upon write().
+	The same issue was seen with mpirun.
+	The following can be used to reproduce this
+	locally at a terminal (in most invocations):
+
+	  $ { dd iflag=nonblock count=0 status=none;

+
+	all: add broken pipe detection while waiting for input
+	When a program's output becomes a broken pipe, future attempts to write
+	to that ouput will fail (SIGPIPE/EPIPE).  Once it is known that all
+	future write attepts will fail (due to broken pipes), in many cases it
+	becomes pointless to wait for further input for slow devices like ttys.
+	Ideally, a program could use this information to exit early once it is
+	known that future writes will fail.
+
+	Introduce iopoll() to wait on a pair of fds (input & output) for input
+	to become ready or output to become a broken pipe.
+
+	This is relevant when input is intermittent (a tty, pipe, or socket);
+	but if input is always ready (a regular file or block device), then
+	a read() will not block, and write failures for a broken pipe will
+	happen normally.
+
+	Introduce iopoll_input_ok() to check whether an input fd is relevant
+	for iopoll().
+
+	Experimentally, broken pipes are only detectable immediately for pipes,
+	but not sockets.  Errors for other file types will be detected in the
+	usual way, on write failure.
+
+	Introduce iopoll_output_ok() to check whether an output fd is suitable
+	for iopoll() -- namely, whether it is a pipe.
+
+	iopoll() is best implemented with a native poll(2) where possible, but
+	fall back to a select(2)-based implementation platforms where there are
+	portability issues.  See also discussion in tail.c.
+
+	In general, adding a call to iopoll() before a read() in filter programs
+	also allows broken pipes to "propagate" backwards in a shell pipeline.
+
+	* src/iopoll.c, src/iopoll.h (iopoll): New function implementing broken
+	pipe detection on output while waiting for input.

+	cp,install,mv: add --debug to explain how a file is copied

+	Also the --reflink and --sparse options directly impact the operation.

+
+	wc: add --total={auto,never,always,only} option

+
+	   wc-no-total() { wc "$@" /dev/null | head -n-2; }
+
+	As well as being non obvious, it's also non general.
+	It would give a non failure, but zero count if passed a file on stdin.
+	Also it doesn't work in conjunction with the --files0-from option,

+	   { find files -print0; printf '%s\0' /dev/null; } |
+	   wc --files0-from=- |

+
+	Also getting just the total can be awkward as file names

+
+	rm: fix diagnostics on I/O error
+	I ran into this problem when attempting to recursively
+	remove a directory in a filesystem on flaky hardware.
+	Although the underlying readdir syscall failed with errno == EIO,
+	rm issued no diagnostic about the I/O error.
+
+	Without this patch I see this behavior:
+
+	  $ rm -fr baddir
+	  rm: cannot remove 'baddir': Directory not empty
+	  $ rm -ir baddir
+	  rm: descend into directory 'baddir'? y
+	  rm: remove directory 'baddir'? y
+	  rm: cannot remove 'baddir': Directory not empty
+
+	With this patch I see the following behavior, which
+	lets the user know about the I/O error when rm tries
+	to read baddir's directory entries:
+
+	  $ rm -fr baddir
+	  rm: cannot remove 'baddir': Input/output error
+	  $ rm -ir baddir
+	  rm: cannot remove 'baddir': Input/output error
+
+	* src/remove.c (Ternary): Remove.  All uses removed.
+	(get_dir_status): New static function.
+	(prompt): Last arg is now directory status, not ternary.
+	Return RM_USER_ACCEPTED if user explicitly accepted.
+	All uses changed.
+	Report any significant error in directory status right away.
+	(prompt, rm_fts): Use get_dir_status to get directory status lazily.
+	(excise): Treat any FTS_DNR errno as being more descriptive, not
+	just EPERM and EACCESS.  For example, EIO is more descriptive.
+	(rm_fts): Distinguish more clearly between explicit and implied
+	user OK.
+	* src/remove.h (RM_USER_ACCEPTED): New constant.
+	(VALID_STATUS): Treat it as valid.
+	* src/system.h (is_empty_dir): Remove, replacing with ...
+	(directory_status): ... this more-general function.
+	All uses changed.  Avoid undefined behavior of looking at

+	doc: use bold style for man page references
+	It's more common to use bold style than not,

+
+	* man/help2man: Implement a --bold-refs option that

+
+2022-02-15  Pádraig Brady  <P@draigBrady.com>
+
+	dircolors: consider COLORTERM as well as TERM env vars
+	COLORTERM is an environment used usually to expose truecolor support in
+	terminal emulators.  Therefore support matches on that in addition
+	to TERM.  Also set the default COLORTERM match pattern so that
+	we apply colors if COLORTERM is any value.
+
+	This implicitly supports a terminal like "foot"
+	without a need for an explicit TERM entry.
+
+	* NEWS: Mention the new feature.
+	* src/dircolors.c (main): Match COLORTERM like we do for TERM.
+	* src/dircolors.hin: Add default config to match any COLORTERM.

+	the documentation.  I hope things are nailed down better now.
+	* doc/sort-version.texi: Distinguish more carefully between

+	compare equal, since they now can.  Improve readability in
+	various ways.  Make it clearer that a suffix can be the

+
+	doc: adust --help, --version alignment
+	* src/system.h: Adjust the alignment of the --help

+	This better aligns with the descriptions of most commands,
+	and also aligns with the minimum column a description must
+	start at to ensure a blank line is not output when a description
+	follows an option on a line by itself.
+
+	doc: rmdir: improve --help formatting
+	* src/rmdir.c (usage): Move description to column 21,
+	so that a --long-option on its own line without a
+	trailing description, doesn't have an erroneous blank
+	line inserted between the option and description.
+	Also group descriptions with blank lines rather than indents,

+
+	doc: improve version-sort doc
+	* doc/coreutils.texi, doc/sort-version.texi:
+	Capitalize “Coreutils”.
+	* doc/sort-version.texi: Don’t emphasize natural sort so much,
+	since Coreutils has just version sort.
+	Use the term “lexicographic” instead of “alphabetic” or “standard”.
+	Suggest combining ‘V’ with ‘b’, and show why ‘b’ is needed.
+	Use shorter titles for sections, as GNU Emacs displays info poorly
+	when titles are too long to fit in a line.
+	Use @samp instead of @code for samples of data.
+	Do not use @samp{@code{...}}; @samp{...} should suffice and
+	double-nesting looks bad with Emacs.
+	Omit blank lines in examples that would not be present
+	in actual shell sessions.
+	Quote with `` and '', not with " or with '.
+	Mention dpkg --compare-versions more prominently.
+	Don’t rely on "\n" being equivalent to "\\n" in shell args.
+	Prefer Unicode name for hyphen-minus.

+	cksum: use more exact selection of digest algorithms
+	Use more constrained argument matching
+	to improve forward compatibility and robustness.
+
+	For example it's better that `cksum -a sha3` is _not_
+	equivalent to `cksum -a sha386`, so that a user
+	specifying `-a sha3` on an older cksum would not be surprised.
+
+	Also argmatch() is used when parsing tags from lines like:
+	SHA3 (filename) = abcedf....
+	so it's more robust that older cksum instances to fail
+	earlier in the parsing process, when parsing output from
+	possible future cksum implementations that might support SHA3.

+	Coreutils mistakenly did not list xstrndup as a module
+	that it depends on directly.  When the latest Gnulib removed
+	the dirname module's dependency on xstrndup, this mistake
+	caused coreutils to not build.  Since all of Coreutils's
+	uses of xstrndup know the string length, xmemdup0 is a better
+	match for what's needed.  Since the size args are typically
+	signed or derived from subtracting pointers, the new Gnulib
+	ximemdup0 function is a better match yet.
+	So, use ximemdup0 instead of xstrndup.

+	    [-Werror=stringop-overflow=]
+	    strncat (comment, UT_ID (utmp_ent), utmpsize);

+	And the POSIX spec says that the second (source) parameter

+	ls: use statx instead of stat when available
+	statx allows ls to indicate interest in only certain inode metadata.
+	This is potentially a win on networked/clustered/distributed
+	file systems. In cases where we'd have to do a full, heavyweight stat()
+	call we can now do a much lighter statx() call.
+
+	As a real-world example, consider a file system like CephFS where one
+	client is actively writing to a file and another client does an
+	ls --color in the same directory. --color means that we need to fetch
+	the mode of the file.
+
+	Doing that with a stat() call means that we have to fetch the size and
+	mtime in addition to the mode. The MDS in that situation will have to
+	revoke caps in order to ensure that it has up-to-date values to report,
+	which disrupts the writer.
+
+	This has a measurable affect on performance. I ran a fio sequential
+	write test on one cephfs client and had a second client do "ls --color"
+	in a tight loop on the directory that held the file:
+
+	Baseline -- no activity on the second client:
+
+	WRITE: bw=76.7MiB/s (80.4MB/s), 76.7MiB/s-76.7MiB/s (80.4MB/s-80.4MB/s),
+	       io=4600MiB (4824MB), run=60016-60016msec
+
+	Without this patch series, we see a noticable performance hit:
+
+	WRITE: bw=70.4MiB/s (73.9MB/s), 70.4MiB/s-70.4MiB/s (73.9MB/s-73.9MB/s),
+	       io=4228MiB (4433MB), run=60012-60012msec
+
+	With this patch series, we gain most of that ground back:
+
+	WRITE: bw=75.9MiB/s (79.6MB/s), 75.9MiB/s-75.9MiB/s (79.6MB/s-79.6MB/s),

+	stat: don't explicitly request file size for filenames
+	When calling 'stat -c %N' to print the filename, don't explicitly
+	request the size of the file via statx(), as it may add overhead on
+	some filesystems.  The size is only needed to optimize an allocation
+	for the relatively rare case of reading a symlink name, and the worst
+	effect is a somewhat-too-large temporary buffer may be allocated for
+	areadlink_with_size(), or internal retries if buffer is too small.
+
+	The file size will be returned by statx() on most filesystems, even
+	if not requested, unless the filesystem considers this to be too
+	expensive for that file, in which case the tradeoff is worthwhile.
+
+	* src/stat.c: Don't explicitly request STATX_SIZE for filenames.

+	ln: avoid directory hard-link races
+	Previously, 'ln A B' did 'stat("B"), lstat("A"), link("A","B")'
+	where the stat and lstat were necessary to avoid hard-linking
+	directories on systems that can hard-link directories.
+	Now, in situations that prohibit hard links to directories,

+	doc: csplit: clarify input may not be reproducible from output
+	* doc/coreutils.texi (csplit invocation): Clarify that
+	portions of the input may be skipped and thus the input
+	may not be reproducible by just concatenating the output files.
+	Fixes https://bugs.gnu.org/32317

+	df: omit redundant comparison
+	Trivial inefficiency reported by Bruno Haible in:
+	http://lists.gnu.org/r/bug-gnulib/2018-07/msg00109.html
+	* src/df.c (hide_problematic_chars): Omit redundant test.
+
+	df: tune slightly
+	* src/df.c (get_header, get_dev):
+	Avoid calling mbswidth twice when once will do.
+
+	df: avoid multibyte character corruption on macOS
+	This improves on the earlier fix for the problem reported by
+	Chih-Hsuan Yen (Bug#32236), by also looking for other control
+	characters and for encoding errors.
+	* src/df.c: Include wchar.h and wctype.h instead of c-ctype.h.
+	(hide_problematic_chars): Process the string as multibyte.
+	Use iswcntrl, not c_iscntrl.

+
+	df: avoid multibyte character corruption on macOS
+	* src/df.c (hide_problematic_chars): Use c_iscntrl() as
+	passing 8 bit characters to iscntrl() is not supported on macOS.
+	* NEWS: Mention the bug fix.
+	Fixes https://bugs.gnu.org/32236

+
+	doc: improve documentation of binary prefixes
+	* doc/coreutils.texi (Common options):
+	* src/dd.c, src/head.c, src/od.c, src/stdbuf.c, src/tail.c (usage):
+	* src/system.h (emit_size_note):
+	Mention binary prefixes (Bug#32242).

+
+	tests: avoid false failure on sparc 32 bit
+	* tests/rm/rm-readdir-fail.sh: Skip the test entirely on 32 bit,
+	so we avoid conflating the 32bit and 64 bit types, as that
+	triggers alignment issues (SIGBUS) on Gentoo sparc.
+	Fixes https://bugs.gnu.org/29886

+
+	build: update gnulib submodule to latest
+	* bootstrap.conf, src/copy.c, src/mv.c, src/shred.c:
+	Adjust to renaming of renameat2 to renameatu.

+
+	tests: fix skipping in some tests
+	* tests/cp/cp-a-selinux.sh: Use 'skip_' rather than the probably
+	undefined 'skip'.
+	* tests/du/2g.sh: Likewise.
+	* tests/install/install-Z-selinux.sh: Likewise.
+	* tests/misc/chcon.sh: Likewise.
+	* tests/misc/selinux.sh: Likewise.
+	* tests/mkdir/restorecon.sh: Likewise.
+	* cfg.mk (sc_prohibit-skip): A new syntax check to catch the issue.

+
+	maint: init.cfg: fix a minor test-related quoting bug
+	* init.cfg (require_membership_in_two_groups_): This fixes a bug
+	introduced by me in v8.15-8-gdd0e4c562.  Luckily, the consequence
+	of low-probability triggering the bug was the mere added backslash
+	in the diagnostic: "...but running id -G\ either...".  It would be
+	triggered in a test failure for one who is a member of only one or
+	fewer groups.
