* src/paste.c (collapse_escapes): This is the central --delimiters
parsing function, so adjust to handle multi-byte chars with
mcel_scanz(). Populate a delimiters length array to support
characters of differing lengths.
(paste_serial): Use the delimiters length array to output
the appropriate delimiter.
(paste_parallel): Likewise.
* tests/paste/multi-byte.sh: A new test.
* tests/local.mk: Reference the new test.
* NEWS: Mention the improvement.
* src/paste.c (usage): Mention how lines are processed
with and without the -s option. Also mention that -d
supports backslash escapes.
* doc/coreutils.texi (paste invocation): Likewise.
Also detail the backslash escapes, noting which are non-POSIX.
* src/ptx.c: Include octhexdigits.h.
(HEXTOBIN, ISODIGIT, OCTTOBIN): Remove macros.
(unescape_string): Use the macros from octhexdigits.h instead of the
removed macros.
Following on from commit v9.8-60-g8ba47d09a ...
Without libselinux installed, runcon and chcon stub binaries
will not be built by default. We separate these utilities out
to a separate "not built unless appropriate" class, so that
we can add these to EXTRA_MANS so that the 'check-x-vs-1'
target doesn't fail, and the 'dist' target includes
these man pages.
* build-aux/gen-lists-of-programs.sh: Separate out
build_if_appropriate_progs, and propagate that through
to no_install_progs_default which populates EXTRA_MANS.
* src/local.mk: Separate out build_if_appropriate__progs
for clarity and consistency.
* gnulib: Update to latest mainly to pull in selinux module fixes.
* NEWS: Mention the build fix to honor --with-selinux building
stub chcon and runcon binaries on systems without libselinux.
* src/cksum.c (output_file, digest_check): Check if standard output has
it's error flag set after printing.
* tests/misc/write-errors.sh: Add a test case that would previously run
forever.
* NEWS: Mention the improvement. Reorder alphabetically.
The 'readlink' and 'realpath' programs have an uncommon case where they
can run for a very long time. When canonicalizing file names longer than
PATH_MAX, we have to call 'openat' for each directory up the tree until
we reach root which takes a long time. Here is an example of the current
behavior:
$ mkdir -p $(yes a/ | head -n $((32 * 1024)) | tr -d '\n')
$ while cd $(yes a/ | head -n 1024 | tr -d '\n'); do :; \
done 2>/dev/null
$ pwd | tr '/' '\n' | wc -l
32771
$ env time --format=%E readlink -f $(yes . | head -n 5) > /dev/full
readlink: write error: No space left on device
Command exited with non-zero status 1
0:59.72
$ env time --format=%E realpath $(yes . | head -n 5) > /dev/full
realpath: write error: No space left on device
Command exited with non-zero status 1
1:00.32
It is better to exit as soon as there is an error writing to standard
output:
$ env time --format=%E readlink -f $(yes . | head -n 5) > /dev/full
readlink: write error: No space left on device
Command exited with non-zero status 1
0:11.88
$ env time --format=%E realpath $(yes . | head -n 5) > /dev/full
realpath: write error: No space left on device
Command exited with non-zero status 1
0:12.04
* src/readlink.c (main): Check if standard output has it's error flag
set after printing a file name.
* src/realpath.c (process_path): Likewise.
* NEWS: Mention the improvement.
We disallow `cksum --tag --check` which is fine,
but the error should be consistent with md5sum,
and less confusing, as it currently mentions
"--binary" and "--text" which weren't specified.
We disallow `cksum --tag --text` which is fine,
but we should also disallow `cksum --text --tag`.
We should honor an explicit --binary (output *)
with this combination of options:
cksum --binary --tag --untagged -a md5 /dev/null
Note this also makes both of `cksum -a md5` and
`cksum --tag -a md5` consistently use binary mode
when reading from a tty on systems like MinGW
where O_BINARY is set.
* src/cksum.c (main): Adjust --text,--binary
and --tag,--untagged option processing.
* tests/cksum/cksum-a.sh: Add test cases.
* tests/cksum/cksum-c.sh: Likewise.
* NEWS: Mention the improvement.
Fixes https://github.com/coreutils/coreutils/issues/163
* tests/chmod/partial-fail.sh: Test readablility of mode 0 files
independently, to avoid false failure, e.g., when run as root.
Reported by Bruno Haible.
* tests/tail/overlay-headers.sh (cleanup_): Ensure we send SIGCONT
to the tail process, otherwise we would hang if the test is terminated
while the tail process is in stopped state.
(wait4stopped_): A new function to ensure tail is in the stopped state
before we start writing to the monitored files.
Also remove "---disable-inotify" from $fastpoll so we actually
test the inotify code (where supported).
Also remove the timeout(1) wrapper, so we actually suspend tail(1).

This aligns with `fold -w` and BSD `fmt` implementations.
* src/fmt.c (fmt_paragraph): Check len <= max_width.
* tests/fmt/width.sh: Add a new test.
* tests/local.mk: Reference the new test.
* NEWS: Mention the change in behavior.
Addresses part of https://bugs.gnu.org/79497
* init.cfg (bad_unicode): New function, copied from
tests/fold/fold-characters.sh with the NUL removed.
* tests/fold/fold-characters.sh (bad_unicode): Rename to
bad_unicode_with_nul. Reformat long line.
* tests/mktemp/bad-unicode.sh: New test.
* tests/local.mk (all_tests): Add the new test.
Consider:
1. In infer_scantype():
- SEEK_DATA returns 0
- hole punched at 0
- SEEK_HOLE returns 0 (now a hole)
- Cache scan_inference->hole_start = 0
2. In lseek_copy():
- data written at 0
- ext_start = 0, use cached hole_start = 0
- ext_len = 0
- now loop doesn't progress
* src/copy-file-data.c (lseek_copy): Apply a more defensive check
to ensure we only use the cached offsets in SCAN_INFERENCE once.
This protects against an infinite loop where an extent (at SRC_POS)
flip flops between data and hole extent while infer_scantype()
and lseek_copy() are inspecting it. I.e. ensure we use SEEK_HOLE
to progress the copy.
* tests/cp/nfs-removal-race.sh: This test was invalid since v8.32
as we now use fstatat() rather than stat(). Also since commit
v9.0-66-ge2daa8f79 we leverage the errno from open(O_DIRECTORY)
to avoid a stat, so pass --no-target-directory to ensure fstatat()
is called.
Discussed in https://github.com/coreutils/coreutils/pull/161
glibc 2.33 removed __xstat, making stat() a direct symbol. This test
previously only intercepted __xstat, causing it to skip on modern glibc
with 'LD_PRELOAD was ineffective'.
Changes:
- Intercept both __xstat (glibc < 2.33) and stat (glibc >= 2.33)
- Only mark 'preloaded' when stat is called on destination 'd',
ensuring the test verifies cp actually stats the destination
Align the -t implementation with the Heirloom project.
* src/ptx.c (usage): Describe -t, and also mention
the default width is 72 when not used.
* doc/coreutils.texi (ptx invocation): Likewise.
(main): Override the default width if -t is specified.
* tests/ptx/ptx.pl: Add test cases.
* NEWS: Mention the change in behavior.
The bad-speed test runs 'stty ispeed 9600' without a --file argument,
which requires a controlling terminal. Without it, stty fails early with
'Inappropriate ioctl for device' before reaching cfsetispeed, causing
the test to skip with a misleading 'LD_PRELOAD interception failed'
message.
* tests/stty/bad-speed.sh: Add require_controlling_input_terminal_
to match the other stty tests (stty.sh, stty-pairs.sh, stty-row-col.sh,
stty-invalid.sh) which all require a controlling terminal.

Commit v9.8-95-g4c0cf3864 intended to initialize
ext_start to src_pos, as was described at:
https://lists.gnu.org/r/coreutils/2025-11/msg00035.html
However ipos was inadvertently used, which is only
valid the first time through the loop.
* src/copy-file-data.c (lseek_copy): Use scan_inference->hole_start
only with the initial offset passed to lseek_copy().
* NEWS: Mention the bug fix.
Reported at https://github.com/coreutils/coreutils/issues/159
* tests/df/no-mtab-status-masked-proc.sh: A new test similar
to no-mtab-status.sh but should work with static builds.
* tests/local.mk: Reference the new test.
https://github.com/coreutils/coreutils/pull/156
* tests/env/env-signal-handler.sh: Test that --ignore-signal with no
options also ignores real-time signals. Test that real-time signals can
be ignored by explicitly listing them.
* src/getlimits.c (SIGRTMIN): Define to zero if signal.h does not define
this constant.
(SIGRTMAX): Define to SIGRTMIN - 1 if signal.h does not define this
constant.
(main): Print SIGRTMIN and SIGRTMAX.
