coreutils/doc, branch v9.8

doc: don't capitalize the first letter of cgroup

2025-09-20T14:21:41Z

This is the correct way to write it as described in the documentation: . * doc/coreutils.texi (nproc invocation): Use cgroup instead of Cgroup.

doc: add hardware acceleration configuration docs

2025-09-16T23:22:50Z

* NEWS: Mention the new GLIBC_TUNABLES feature. * doc/coreutils.texi (Hardware Acceleration): A new node detailing the build time and run time configuration options.

doc: update the md5/sha1 "weak hash" advisory

2025-09-04T17:19:15Z

* doc/coreutils.texi: Adjust advisory for md5sum and sha1sum to include "sha3", and also the more general `cksum -a` interface.

cksum: prefer -a sha2 -l ###, to -a sha###

2025-09-04T13:49:07Z

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.

cksum: add support for SHA-3

2025-09-04T05:29:33Z

* 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.

fold: add the --characters option

2025-08-23T05:09:50Z

* src/fold.c: Include mcel.h. (count_bytes): Remove variable. (counting_mode, last_character_width): New variables. (shortopts, long_options): Add the option. (adjust_column): If --characters is in used account for number of characters instead of their width. (fold_file): Use getline and iterate over the result with mcel functions to handle multibyte characters. (main): Check for the option. * src/local.mk (src_fold_LDADD): Add $(LIBC32CONV), $(LIBUNISTRING), and $(MBRTOWC_LIB). * tests/fold/fold-characters.sh: New file. * tests/fold/fold-spaces.sh: New file. * tests/fold/fold-nbsp.sh: New file. * tests/local.mk (all_tests): Add the tests. * NEWS: Mention the new option. * doc/coreutils.texi (fold invocation): Likewise.

maint: prefer https to http

2025-08-19T18:41:17Z

* doc/sort-version.texi (Other version/natural sort implementations): Use https in documentation link. * tests/chmod/symlinks.sh: Use https in license text.

nproc: honor cgroup v2 CPU quotas

2025-08-19T16:24:21Z

* NEWS: Mention the new feature. * doc/coreutils.texi (nproc invocation): Mention that cgroup CPU quotas can limit the reported number. * gnulib: Update to new nproc gnulib implementation: https://github.com/coreutils/gnulib/commit/9b07115f4a

realpath: improve doc and NEWS

2025-08-15T04:08:44Z

tsort: add do-nothing -w option

2025-08-15T00:35:23Z

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.
