* NEWS: Mention the new GLIBC_TUNABLES feature.
* doc/coreutils.texi (Hardware Acceleration): A new node
detailing the build time and run time configuration options.
* src/fold.c (write_out): A new helper to check all writes.
(fold-file): Use write_out() for all writes.
* tests/fold/fold-zero-width.sh: Adjust to writing more
data in various patterns, rather than two buffers of NULs.
This is a more robust memory bound check, and the '\303' case
tests this particular logic change.
* NEWS: fold now exits immediately, not just promptly.
* NEWS: Mention the improvement.
* src/fold.c (fold_file): Check for write errors
after each buffer read from stdin.
* tests/misc/write-errors.sh: Add test cases.
* src/copy-file-data.c (sparse_copy, lseek_copy)
(copy_file_data): Prefer idx_t to size_t.
(copy_file_data): Defend against st_size < 0, which can happen on
ancient buggy platforms. Check for overflow; the old code was
wrong on theoretical-but-valid hosts where SIZE_MAX <= INT_MAX.
* src/copy-file-data.c (write_zeros): New args abuf, buf_size.
Use the lazily-allocated buffer, which most likely already exists,
rather than allocating a separate buffer just for zeros.
This makes the code more reentrant as there is no longer
a need for static storage here. Although there is some CPU
overhead due to the need to zero out the buffer for each file,
the overhead is relatively small as the buffer is smallish
and should be cached. All callers changed.
This doesn’t change behavior; it simplifies future changes.
* src/copy-file-data.c (sparse_copy, lseek_copy, copy_file_data):
Return the number of bytes copied, or -1 on failure,
instead of merely returning a success indication.
All callers changed.
This does not affect current coreutils behavior;
it is merely to help make copy_file_data more useful in the future.
* src/copy-file-data.c (lseek_copy): New arg ibytes.
Caller changed.
(copy_file_data): Implement the ibytes arg; formerly
it was always treated as COUNT_MAX, though all callers
currently pass COUNT_MAX so there was no problem in practice.
Port better ancient platforms where OFF_T_MAX is only 2**31 - 1,
but some devices have more than that many bytes.
* src/copy-file-data.c (copy_file_data): Byte count is now
count_t, not off_t. All callers changed. Since we need to check
for overflow anyway, also check for too-small calls to fadvise.
* po/POTFILES.in, src/local.mk (copy_sources): Add the new file.
* src/copy.c: Move the #includes of alignalloc.h, buffer-lcm.h,
fadvise.h, full-write.h, ioblksize.h to copy-file-data.c.
(enum copy_debug_val, struct copy_debug): Move these decls to copy.h.
(punch_hole, create_hole, is_CLONENOTSUP, sparse_copy)
(write_zeros, lseek_copy, HAVE_STRUCT_STAT_ST_BLOCKS)
(enum scantype, struct scan_inference, infer_scantype):
Move to copy-file-data.c.
(copy_reg): Move the data-copying part of this function
to the new function copy_file_data in copy-file-data.c.
* src/copy-file-data.c: New file, taken from part of copy.c.
This is in preparation for splitting this large module.
* src/copy.c (sparse_copy, lseek_copy): New arg DEBUG, used to
identify copy debug info instead of using a static var. All
callers changed.
(lseek_copy, infer_scantype): New args SRC_POS and POS.
Callers changed.
(copy_file_data): New function, with contents taken from copy.
(copy_reg): Call it.
* NEWS: Before commit fb9016d50 (fold: use fread instead of getline,
2025-08-24), fold required that the maximum line size in a file fit into
memory. Document that this is no longer the case.
* src/fold.c (fold_file): Prefer putchar ('\n') to copying characters.
If we do not have room in the output buffer print it since it is not a
full line of text.
* tests/fold/fold-zero-width.sh: New test case.
* tests/local.mk (all_tests): Add it.
This is useful to give better test coverage at least,
and may be useful for users to tune their environment.
* bootstrap.conf: Reference the cpu-supports gnulib module.
* src/cksum.c: Use cpu_supports() rather than __builtin_cpu_supports().
* src/wc.c: Likewise.
* tests/cksum/cksum.sh: Adjust to testing all implementations.
* tests/wc/wc-cpu.sh: A new test to do likewise.
* tests/local.mk: Reference the new wc test.
Finalize was required for base58, but it's a more general mechanism
which simplifies the logic for all encodings
* src/basenc.c (do_decode): Always call base_decode_ctx_finalize(),
rather than the awkward double loop at end of buffer.
* tests/basenc/basenc.pl: Add basenc finalization tests.
* src/local.mk (src_fold_LDADD): Remove $(MBRTOWC_LIB) since it is
already added to LDADD. Remove $(LIBC32CONV) and $(LIBUNISTRING) which
were for an uncommitted patch which used Gnulib's mbfile module.
The meaning of non-file permission umask bits is implementation defined.
On Bionic libc, attempting to set them triggers a FORTIFY runtime check.
$ nohup true
FORTIFY: umask: called with invalid mask -601
Aborted nohup true
* src/nohup.c: (main) Avoid setting non-permission bits in umask.
Just clear the umask to ensure we create nohup.out with u+rw,
as we restore the original umask before the exec().
* tests/misc/nohup.sh: Add a test case.
* NEWS: Mention the bug fix.
* src/basenc.c (has_padding): A more robust helper to
identify padding in the presence of trailing newlines.
(do_decode): Use has_padding() rather than just looking
at the last character.
* tests/basenc/base64.pl: Fully test commit v9.4-53-g378dc38f4
by ensuring partially padded data is diagnosed.
baddecode9 is the case fixed in this commit.
* NEWS: Mention the bug fix.
This implicitly tests the previous commit to
adjust how date(1) handles multiple named format options.
Currrently it tests the following are supported:
chown --quiet --silent
date --rfc-email --rfc-822 --rfc-2822
date --uct --utc --universal
dircolors --bourne-shell --sh
dircolors --csh --c-shell
head --quiet --silent
* tests/misc/option-aliases.sh: A new test to ensure all
option aliases supported by a command are supported.
* Reference the new test.
This avoids a test failure on FreeBSD 14, MacOS 15, and musl.
Fix suggested by Pádraig Brady in:
<https://bugs.gnu.org/79301#32>.
* tests/fold/fold-spaces.sh (isblank): New function. Only run the tests
if the character is treated as blank.
Fixes https://bugs.gnu.org/79301
To make the interface more concise and consistent,
while being backwards compatible.
* src/digest.c (main): Continue to support -a "sha###" but
also support -a "sha2" and treat it like "sha3", except in...
(output_file): ... maintain the legacy tags for better compatability.
* doc/coreutils.texi (cksum invocation): Document the -a sha2 option.
* tests/cksum/cksum-base64.pl: Adjust as per modified --help.
* tests/cksum/cksum-c.sh: Add new supported SHA2-### tagged variant.
* NEWS: Mention the new feature.
* src/digest.c: Include sha3.h.
(BLAKE2B_MAX_LEN): Rename to
DIGEST_MAX_LEN since it is also used for SHA-3.
(sha3_sum_stream): New function.
(enum Algorithm, algorithm_args, algorithm_args, algorithm_types)
algorithm_tags, algorithm_bits, cksumfns, cksum_output_fns): Add entries
for SHA-3.
(usage): Mention that SHA-3 is supported. Mention requirements for
--length with SHA-3.
(split_3): Use DIGEST_MAX_LEN instead of BLAKE2B_MAX_LEN. Determine the
length of the digest for SHA-3. Make sure it is 224, 256, 384, or 512.
(digest_file): Set the digest length in bytes. Use DIGEST_MAX_LEN
instead of BLAKE2B_MAX_LEN. Always append the digest length to SHA3 in
the output.
(main): Allow the use of --length with 'cksum -a sha3'. Use
DIGEST_MAX_LEN instead of BLAKE2B_MAX_LEN. Make sure it is 224, 256,
384, or 512.
* tests/cksum/cksum-base64.pl (@pairs): Add expected sha3 output.
(fmt): Modify the output to use SHA3-512 since that is the default.
(@Tests): Modify arguments for sha3 to use --length=512.
* tests/cksum/cksum-sha3.sh: New test, based on tests/cksum/b2sum.sh.
* tests/local.mk (all_tests): Add the test.
* bootstrap.conf: Add crypto/sha3.
* gnulib: Update to latest commit.
* NEWS: Mention the change.
* doc/coreutils.texi (cksum general options): Mention sha3 as a
supported argument to the -a option. Mention that 'cksum -a sha3'
supports the --length option. Mention that SHA-3 is considered secure.
NetBSD 10 and Solaris 11.4 treat non-breaking spaces as blank
characters unlike glibc.
* src/system.h: Include uchar.h.
(c32isnbspace): New function based on iswnbspace from src/wc.c.
* src/fold.c (fold_file): Use it.
* src/wc.c (iswnbspace): Remove function.
(maybe_c32isnbspace): New function.
(wc, main): Use it.
Fixes https://bugs.gnu.org/79300

* src/copy.c: Include issymlink.h.
(copy_reg): Use issymlink instead of readlinkat.
* src/rmdir.c: Include issymlink.h.
(main): Use issymlink instead of readlink.
* src/tail.c: Include issymlink.h.
(recheck, any_symlinks): Use issymlink instead of readlink.
* src/test.c: Include issymlink.h.
(unary_operator): Use issymlink instead of readlink.
* src/seq.c (main): Avoid possibly innacurate conversion
to long double, for all digit start values.
* tests/seq/seq-long-double.sh: Add a test case.
* NEWS: Mention the improvement.
Fixes https://bugs.gnu.org/79369
Fix allocated size alignment in locales with multi-byte grouping chars.
Tested with: LC_ALL=sv_SE.utf8 ls --size --block-size=\'k
* src/ls.c (print_file_name_and_frills): Don't rely on
printf("%*s", width, string) to pad multi-byte strings appropriately.
Instead work out the padding required and use:
printf("%*s%s", padding, "", string) to pad multi-byte appropriately.
* tests/ls/block-size.sh: Add a test case.
* NEWS: Mention the bug fix.
Fixes https://bugs.gnu.org/79347
* src/digest.c (main): Don't saturate -l to BLAKE2B_MAX_LEN,
so that the subsequent bounds check is performed.
* tests/cksum/b2sum.sh: Add a test case.
* NEWS: Mention the fix introduced in commit v9.5-71-gf2c84fe63
