* doc/coreutils.texi (du invocation): Mention that --threshold has no
effect on the grand total calculated when --total is used.
Addresses https://bugs.gnu.org/71309
The --apparent-size option to 'du' was added in
coreutils-4.5.8 (2003). FreeBSD 8.0 (2009) added the same functionality
under the short option -A. This long option previously had no short
option, so this patch adds -A to be compatible with FreeBSD.
* NEWS: Mention the new short option.
* doc/coreutils.texi: Document the short option.
* src/du.c (usage): Likewise.
(APPARENT_SIZE_OPTION): Remove definition.
(EXCLUDE_OPTION): Define to CHAR_MAX + 1.
(long_options): Use the -A short option for --apparent-size.
(main): Likewise.
* tests/du/apparent.sh: Test that '-b', '-A -B 1', and
'--apparent-size --block-size 1' function the same.
* doc/coreutils.texi (tail invocation): Describe --debug.

* NEWS: Mention the new feature.
* doc/coreutils.texi (shred invocation): Give more details on what
--verbose outputs, to give some indication of its utility.

split out translations to give translators more granular translations.
Make the documentation more accurate following v9.3-80-g5e1e0993b
* doc/coreutils.texi (cksum common options): State that --text and
--binary are actually supported, but only to support emulation
of the legacy utils.
Many people are used to seeing ISO 8601 dates using a period separating
seconds and nanoseconds. This behavior seems to be worth documenting
given the bug reports:
https://bugs.gnu.org/63119https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1118970
* doc/coreutils.texi (Options for date): Mention that
'date --iso-8601=ns' uses a comma as a separator, following the
preference of ISO 8601. Give an example of how to get an ISO 8601 date
with a period separator.

warning to standard error if --compress-program cannot be executed and
the error is different than the previous call. Remove code for the child
process.
(open_temp): Remove code for the child process. Improve error message.
* tests/sort/sort-compress.sh: Add a test case for when the program
specified by --compress-program does not exist.

--delimiter skipping whitespace.
* NEWS: Mention the improvement.

This is for conformance to POSIX.1-2024
* src/tsort.c: Include getopt.h.
(main): Accept and ignore -w. Do not bother altering
the usage message, as the option is useless.
* tests/misc/tsort.pl (cycle-3): New test.
* src/realpath.c (longopts): Add the option.
(main): Likewise.
(usage): Add the option to the --help message.
* tests/misc/realpath.sh: Add a simple test.

* doc/coreutils.texi (basenc invocation): Add an example
using --base58 to generate a unique ID. This also demonstrates
compound usage of the basenc command, to convert to/from binary.
A 58 character encoding that:
- avoids visually ambiguous 0OIl characters
- uses only alphanumeric characters
Described at:
- https://tools.ietf.org/html/draft-msporny-base58-03
This implementation uses GMP (or gnulib's gmp fallback).
Performance is good in comparison to other implementations.
For example when using libgmp on an i7-5600U system,
encoding is 530 times faster, and decoding 830 times faster
than the implementation using arbitrary precision ints in cpython 3.13.
Memory use is proportional to the size of input.
Encoding benchmarks:
$ time yes | head -c65535 | src/basenc --base58 -w0 >file.enc
real 0m0.018s
./configure --quiet --without-libgmp && make -j $(nproc)
$ time yes | head -c65535 | src/basenc --base58 -w0 >file.enc
real 0m3.431s
# dnf install python3-base58
$ time yes | head -c65535 | base58 >file.enc # cpython 3.13
real 0m9.700s
Decoding benchmarks:
$ time src/basenc --base58 -d <file.enc >/dev/null
real 0m0.010s
$ ./configure --without-libgmp && make # gnulib gmp
$ time src/basenc --base58 -d <file.enc >/dev/null
real 0m0.145s
$ time base58 -d <file.enc >/dev/null # cpython 3.13
real 0m8.302s
* src/basenc.c (base_decode_ctx_finalize, base_encode_ctx_init,
base_encode_ctx, base_encode_ctx_finalize): New functions to
provide more general processing functionality.

* src/local.mk: Link basenc with GMP.
* tests/basenc/basenc.pl: Add test cases.

Also, fix commentary to talk about “nonexistent” rather than
“dead” processes, since the code looks for the former not the
latter and the difference matters for zombies.
* src/tail.c (some_writers_exist): Rename from writers_are_dead,
negate the sense, don’t have a special and counterintuitive case
for !nbpids, remove PIDs found not to exist, and avoid some
though not all unlikely races when kernels reuse PIDs.
(tail_forever): Optimize via blocking I/O even if --pid was used,
so long as all the writers no longer exist.
(tail_forever, tail_forever_inotify): Simplify the writers_dead
logic; there is no need to have a local var to track this, since
we can use pids and nbpids now.
(parse_options): Also free and clear pids if !forever.
Signed types let us debug better, by using -fsanitize=undefined.
* doc/local.mk (doc/constants.texi):
Adjust change from macro to enum.
* src/tail.c (COPY_TO_EOF, COPY_A_BUFFER)
(DEFAULT_MAX_N_UNCHANGED_STATS_BETWEEN_OPENS):

(COPY_TO_EOF, COPY_A_BUFFER): Now negative, not positive.

Prefer count_t to uintmax_t.

be verbose.

-s (--silent), -q (--quiet), and -v (--verbose) in the help message.
(main): Remove spurious newline added by previous commit.
* doc/coreutils.texi (readlink invocation): Mention that -s (--silent)
and -q (--quiet) are not the default when POSIXLY_CORRECT is set.

variable is set.

* src/factor.c (PROVE_PRIMALITY): Now defaults to false.
(mp_prime_p): Help the compiler by telling it mpz_prob_prime_p
returns nonnegative.
* tests/factor/create-test.sh (bigprime): Test 2^400 - 593,
since that’s now practical.
* tests/local.mk (factor_tests): Add new test.
* doc/coreutils.texi (cksum common options): Reorder and tweak the info
to make it clearer that --check does not support the legacy crc output
from the cksum command.
Reported at https://bugs.debian.org/1108363
* src/od.c (dump_strings): There are three related issues here
due to not accounting for the terminating NUL char appropriately.
1. Ensure BUF always has enough space for the terminating NUL.
This avoids CWE-122: Heap-based Buffer Overflow,
where we wrote a single NUL byte directly after the allocated buffer.
I.e., there should be no buffer overflow with:
printf '%100s' | od -N100 -S1
2. Ensure we support -S == -N (END_OFFSET - STRING_MIN == ADDRESS):
I.e., there should be output with:
printf '%100s' | od -N10 -S10
3. Ensure we always output a valid address by ensuring
the ADDRESS and I variables are kept in sync.
I.e., this should output address 0000000 not 1777777777777777777777:
printf '%100s' | od -N10 -S1
As well as fixing these we simplify by using a single loop
to read the data, rather than two.
* doc/coreutils.texi (od invocation): Clarify that -N
implicitly NUL terminates strings.
* tests/od/od-N.sh: Add test cases.
* NEWS: Mention the bug fixes.
Fixes https://bugs.gnu.org/78880
* doc/coreutils.texi (stty invocation): Remove now imprecise
list of speeds given we may now support higher or arbitrary speeds.
Mention that we may support higher or arbitrary speeds.
* src/tty.c (TTY_USAGE): Rename from TTY_FAILURE, since this
is used only for usage failures. All uses changed.
(TTY_TTYNAME_FAILURE): New constant.
(main): Remove no-longer-needed assignment of ENOENT to errno.
Make status-setting clearer too.
Report an error if ttyname fails even though stdin is a terminal,
instead of silently pretending that stdin is not a terminal.
* tests/tty/tty.sh: Test for this issue. This should fix Bug#78244.
* doc/coreutils.texi: Use @dots{} after [OPTION],
to be consistent with man pages.
* src/printenv.c (Usage): Remove unneeded "...".
* src/timeout.c (Usage): Add needed "...",
and also remove redundant [OPTION] only form.

NFS (on Linux 6.12 at least) was seen to return EACCES
from listxattr() for files without read access.
We started using listxattr() in coreutils 9.4.

to '?', rather than displaying the error.
* doc/coreutils.texi (ls invocation): Document the '?' flag.
* NEWS: Mention the bug fix.
