Support `cksum --check FILE` without having to specify a digest
algorithm, allowing for more generic file check instructions.
This also supports mixed digest checksum files, supporting
more robust multi digest checks.
* src/digest.c (algorithm_from_tag): A new function to
identify the digest algorithm from a tagged format line.
(split3): Set the algorithm depending on tag, and update
the expected digest length accordingly.
* tests/misc/cksum-c.sh: Add a new test.
* tests/local.mk: Reference the new test.
* tests/misc/md5sum.pl: Adjust to more generic error.
* tests/misc/sha1sum.pl: Likewise.
* doc/coreutils.texi (md5sum invocation): Mention the new -c feature.
* NEWS: Mention the new feature.
Add message digest sm3, which uses the OSCCA SM3 secure
hash (OSCCA GM/T 0004-2012 SM3) generic hash transformation.
* bootstrap.conf: Add the sm3 module.
* doc/coreutils.texi: Mention the cksum -a option.
* src/digest.c: Provide support for --algorithm='sm3'.
* tests/misc/sm3sum.pl: Add a new test (from Tianjia Zhang)
* tests/local.mk: Reference the new test.
* NEWS: Mention the new feature.
Tested-by: Tianjia Zhang <tianjia.zhang@linux.alibaba.com>
* src/digest.c: Organize HASH_ALGO_CKSUM to be table driven,
and amalgamate all digest algorithms.
(main): Parse all options if HASH_ALGO_CKSUM, and disallow
--tag, --zero, and --check with the traditional bsd, sysv, and crc
checksums for now.
* src/local.mk: Reorganize to include all digest modules in cksum.
* tests/misc/cksum-a.sh: Add a new test.
* tests/misc/b2sum.sh: Update to default to checking with cksum,
as b2sum's implementation diverges a bit from the others.
* tests/local.mk: Reference the new test.
* doc/coreutils.texi (cksum invocation): Adjust the summary to
identify the new mode, and document the new --algorithm option.
* man/cksum.x: Adjust description to be more general.
* man/*sum.x: Add [See Also] section referencing cksum(1).
* NEWS: Mention the new feature.
* cfg.mk: Adjust cksum.c to not require config.h
and support a main (for crctab) without calling bindtextdomain().
* po/POTFILES.in: Remove cksum_pclmul.c since it no longer
concerns itself with diagnostics.
* src/cksum.c: Refactor to just providing stream digest,
and digest printing functionality.
* src/cksum.h: Adjust to the new interface.
* src/cksum_pclmul.c: Remove diagnostics, and determine errors
internally.
* src/crctab.c: Separate from cksum.h since that's now included
multiple times.
* src/digest.c: Provide cksum(1) functionality if -DHASH_ALGO_CKSUM
* src/local.mk: Adjust to new crctab.c and HASH_ALGO_CKSUM define.
This should have been part of commit v8.32-113-gb73b9fcb1
* doc/coreutils.texi (cksum invocation): Add the --debug description.
* src/cksum.c (usage): Likewise.
(main): Also give explicit indication when using generic hardware.
Since digest will be providing all digest functionality,
refactor sum.c into it.
* po/POTFILES.in: sum.c no longer has translatable strings so remove.
* src/digest.c: Call out to new stream interfaces in sum.c
* src/local.mk: Adjust sources for the sum binary.
* src/sum.c: Provide a stream interface for BSD and SYSV digests.
* src/sum.h: A new file to declare the exported functions in sum.c
md5sum.c will be the base for all digest functions,
so rename accordingly.
* src/md5sum.c: Rename to ...
* src/digest.c: ... renamed from md5sum.c
* scripts/git-hooks/commit-msg: Allow digest: commit prefix.
* po.POTFILES.in: Adjust to new name.
* src/local.mk: Likewise.
* doc/coreutils.texi (whoami invocation): Clarify it prints names,
not numeric IDs.
* man/whoami.x: Likewise.
* man/logname.x: Reference getlogin(3).
* src/logname.c: Clarify that it prints the login name,
rather than the name of the effective user ID.
Fixes https://bugs.gnu.org/48894
* tests/ls/stat-vs-dirent.sh: Skip the test if we can't stat(1),
as the file may have been removed, or have a malformed name
due to '\n' etc. in the file name.
* gnulib: Update to latest. This fixes a gnulib test failure in base64,
among other fixes.
* cfg.mk: Disable sc_indent as auto indent is too invasive for now.
Adjust to output the file name if any name parameter is passed.
This is consistent with sum -s, cksum, and sum implementations
on other platforms. This should not cause significant compat
issues, as multiple fields are already output, and so already
need to be parsed.
* src/sum.c (bsd_sum_file): Output the file name
if any name parameter is passed.
* tests/misc/sum.pl: Adjust accordingly.
* doc/coreutils.texi (sum invocation): Likewise.
* NEWS: Mention the change in behavior.
* tests/misc/help-version.sh: Test that /dev/full causes
shell printf to fail. This ports better to NetBSD 9.88.46,
where it doesn’t. Problem reported by Nelson H. F. Beebe.
* tests/misc/help-version.sh: Merge gzip-related changes
back from gzip/tests/help-version. This fixes problems
when TERM is not 'dumb', and should simplify maintenance.
Emil Lundberg <lundberg.emil@gmail.com> reports in
https://bugs.gnu.org/49741 about a 'basenc --base64 -d' decoding bug.
The input buffer length was not divisible by 3, resulting in
decoding errors.
* NEWS: Mention fix.
* src/basenc.c (DEC_BLOCKSIZE): Change from 1024*5 to 4200 (35*3*5*8)
which is divisible by 3,4,5,8 - satisfying both base32 and base64;
Use compile-time verify() macro to enforce the above.
* tests/misc/basenc.pl: Add test.
This patch modifies basenc to prefer signed integers to
unsigned, as signed are less error-prone.
This patch also updates Gnulib to to latest, which updates Gnulib’s
base32 and base64 modules to prefer signed to unsigned integers.
* src/basenc.c: Include idx.h.
(struct base2_decode_context): Use unsigned char, not unsigned
for an octet that must fit in an unsigned char.
(base_encode, struct base_decode_context)
(base64_decode_ctx_wrapper, prepare_inbuf, base64url_encode)
(base64url_decode_ctx_wrapper, base32_decode_ctx_wrapper)
(base32hex_encode, base32hex_decode_ctx_wrapper, base16_encode)
(base16_decode_ctx, z85_encode, Z85_HI_CTX_TO_32BIT_VAL)
(z85_decoding, z85_decode_ctx, base2msbf_encode)
(base2lsbf_encode, base2lsbf_decode_ctx, base2msbf_decode_ctx)
(wrap_write, do_encode, do_decode, main):
Prefer signed integers to unsigned.
(main): Treat extremely large wrap columns as if they were
infinite; that’s good enough. Since we’re now using xstrtoimax,
this allows ‘-w -0’ (same as ‘-w 0’).
* tests/misc/base64.pl (gen_tests): -w-0 is no longer an error.
find-mount-point.h rightly includes <stdlib.h> for its use
of _GL_ATTRIBUTE_DEALLOC_FREE, which uses free, yet that new
inclusion provoked a syntax-check failure. Exempt this header
file as we've done for others.
* cfg.mk (exclude_file_name_regexp--sc_system_h_headers):
Add find-mount-point.h to the regexp.
(sc_system_h_headers): Use grep -E, for a more readable regexp.
This better tests the SEEK_HOLE logic which
replaced the original fiemap hole identification logic.
Also it avoids a false failure in sparse-2.sh
on reflink supporting file systems, where we
try to correlate the file sizes produced by cp and dd.
* tests/cp/sparse-2.sh: s/cp/cp --reflink=never/
* tests/cp/sparse-extents-2.sh: Likewise.
* tests/cp/sparse-extents.sh: Likewise.
* tests/cp/sparse-perf.sh: Likewise.
* tests/cp/sparse.sh: Likewise.

This is so that commands like ‘fmt - -’ read from stdin
both times, even when it is a tty. Fix some other minor
issues that are related.
* src/blake2/b2sum.c (main):
* src/cksum.c (cksum):
* src/cut.c (cut_file):
* src/expand-common.c (next_file):
* src/fmt.c (fmt):
* src/fold.c (fold_file):
* src/md5sum.c (digest_file, digest_check):
* src/nl.c (nl_file):
* src/od.c (check_and_close):
* src/paste.c (paste_parallel, paste_serial):
* src/pr.c (close_file):
* src/sum.c (bsd_sum_file):
Use clearerr on stdin so that stdin can be read multiple times
even if it is a tty. Do not assume that ferror preserves errno as
POSIX does not guarantee this. Coalesce duplicate diagnostic
calls.
* src/blake2/b2sum.c (main):
* src/fmt.c (main, fmt):
Report read error, even if it's merely fclose failure.
* src/fmt.c: Include die.h.
(fmt): New arg FILE. Close input (reporting error) if not stdin.
All callers changed.
* src/ptx.c (swallow_file_in_memory): Clear stdin's EOF flag.
* src/sort.c (xfclose): Remove unnecessary feof call.
Problem reported by Michael Debertol (Bug#50070).
* NEWS: Mention the fix.
* src/chmod.c (struct change_status): New struct, replacing the
old enum Change_status. All uses changed.
(describe_change): Distinguish between cases depending on
whether 'stat' or its equivalent succeeded. Report a line
of output even if 'stat' failed, as that matches the documentation.
Rework to avoid casts.
(process_file): Do not output nonsense modes computed from
uninitialized storage, removing a couple of IF_LINTs. Simplify by
defaulting to CH_NO_STAT.
If the command-line argument is automounted, df would use
stat info that became wrong after the following open.
* NEWS: Mention the fix (bug#50012).
* src/df.c (automount_stat_err): New function.
This fixes the hang on fifos in a better way, by using O_NONBLOCK.
(main): Use it.
We must delay handling when \r is the last character
of the buffer being processed, as the next character
may or may not be \n.
* src/cat.c (pending_cr): A new global to record whether
the last character processed (in -E mode) is '\r'.
(cat): Honor pending_cr when processing the start of the buffer.
(main): Honor pending_cr if no more files to process.
* tests/misc/cat-E.sh: Add test cases.
Fixes https://bugs.gnu.org/49925
Pacify GCC 11.1 -fanalyzer.
* src/uniq.c (check_file): Use simpler test to check whether this
is the first time through the loop. Although the old test was
correct, the new one is easier to understand and perhaps a tiny
bit more efficient.
Caught by GCC 11.1 -fanalyzer.
* src/numfmt.c (simple_strtod_int): Remove unnecessary test of
*endptr vs NULL. Presumably this was a typo and **endptr was
intended instead of *endptr, but an **endptr test is also
unnecessary since c_isdigit (0) returns false.
* doc/coreutils.texi (tr invocation): Provide a summary
list of the available options, which is useful to
provide a quick reminder for those already familiar
with the functionality of tr.
Fixes https://bugs.gnu.org/49764
In documentation and comments, don’t assume that secondary storage
devices are disk devices. Similarly, don’t assume that main memory
uses magnetic cores, which became obsolete in the 1970s.
* src/du.c (usage):
* src/ls.c (usage):
* src/shred.c (usage): Reword to avoid “disk” in usage messages.
* doc/coreutils.texi (ls invocation): Document implementation more
closely. Be more consistent about style. Omit some needless words.
* src/ls.c (usage): Don’t overdocument -f, as the details were wrong.
Omit -1 advice as it’s a bit obsolete now that we have --zero and
is a bit much for --usage output anyway.
* NEWS, doc/coreutils.texi (General output formatting):
* src/ls.c (usage):
Document this.
* src/ls.c (ZERO_OPTION): Rename from NULL_OPTION.
All uses changed.
(long_options): Rename --null to --zero.
(dired_dump_obstack, main, print_dir): Use '\n' instead of
eolbyte where eolbyte must equal '\n'.
(decode_switches): Decode --zero instead of --null.
--zero also implies -1, -N, --color=none, --show-control-chars.
Use easier-to-decipher code to set ‘format’ and ‘dired’.
Reject attempts to combine --dired and --zero.
* tests/local.mk: Adjust to test script renaming.
* tests/ls/zero-option.sh: Rename from tests/ls/null-option.sh,
and test --zero instead of --null.
* src/ls.c (enum time_type, enum sort_type, enum indicator_style)
(enum Dereference_symlink, ignore_mode):
Put ‘= 0’ after default values, since the code relies
on static storage defaulting to zero.
(enum sort_type): Reorder so that -1 can be used to represent unset.
(main): Test print_with_color after parse_ls_color may have reset it.
(decode_line_length): Return the line length instead of setting
static storage. All uses changed. Treat line lengths exceeding
PTRDIFF_MAX as infinite, to avoid pointer-subtraction glitches.
(stdout_isatty): New function, to avoid calling isatty twice.
(decode_switches): Calculate defaults more lazily, to avoid using
syscalls or getenv during startup unless the results are more
likely to be needed. Use -1 to indicate options that haven’t been
set on the command line yet. Move print_with_color test from
here to ‘main’. Suppress bogus GCC warning.
(getenv_quoting_style): Return the quoting style instead of
setting static storage.
(init_column_info): New arg MAX_COLS, to avoid recalculating it.
Caller changed.
* src/ls.c (dired_pos): Now off_t, not size_t, since it counts
output file offsets.
(dired_dump_obstack): This obstack's file offsets are now
off_t, not size_t.
(format_user_or_group, format_user_or_group_width):
ID arg is now uintmax_t, not unsigned long, since uid_t and
gid_t values might exceed ULONG_MAX.
(format_user_or_group_width): Use snprintf with NULL instead of
sprintf with a discarded buffer. This avoids a stack buffer,
and so should be safer.
