<stdbit.h> is in C23 and should be more portable in the long run,
now that Gnulib supports it.
* bootstrap.conf (gnulib_modules): Remove count-leading-zeros.
Add stdc_leading_zeros.
* gl/lib/randperm.c, src/ioblksize.h:
Include stdbit.h instead of count-leading-zeros.h.
* gl/lib/randperm.c (floor_lg): Remove; no longer needed.
(randperm_bound): Use stdc_bit_width instead of floor_lg;
* gl/modules/randperm (Depends-on): Remove count-leading-zeros.
Add stdc_bit_width.
* src/ioblksize.h (io_blksize): Use stdc_leading_zeros_ull
instead of count_leading_zeros_ll.
* configure.ac: Disable GCC 14’s -Wmissing-variable-declarations
in the test directory, as it’s not worth the aggravation there.
Likewise for GCC's -Wsuggest-attribute=cold.
* src/sort.c: Ignore -Wmissing-variable-declarations only
with GCC 14 and newer, since it didn’t exist earlier.
Ignore the warning only when including md5.h, where it
needs to be ignored, as the warning might be useful elsewhere.
* src/cksum.c (main) [CRCTAB]: Generate updated crctab.c (see below).
* src/crctab.c: Include cksum.h, to check consistency
between decl and defn. Include stdio.h since cksum.h needs it.
This patch is part of work done for a project from Google Summer of
Code, see the project details at
<https://summerofcode.withgoogle.com/programs/2024/projects/E9Jp7RUx>.
* src/sleep.c (usage): Directly mention the floating-point option,
which is typical for sleeping milliseconds.
Also reorganize the text to be 3 lines rather than 4.
Similarly to commit v9.4-143-gfcfba90d0,
and enabled for AVX by commit v9.5-25-g0e4450103.
This was seen to improve AVX performance by about 10%
on an AMD 7800X3D (Ryzen 7 (2023)) CPU,
while having neutral AVX performance,
on an Intel i7-5600U (Broadwell-U (2015)) CPU.
With avx not enabled, this gives about a 3% performance boost,
on an Intel i7-5600U.
* src/wc.c: Use the centrally configured optimum buffer size.
* src/wc_avx2.c: Likewise.
* NEWS: Mention the change in performance.
* src/wc_avx2.c (wc_lines_avx2): Change from
_mm256_sub_epi8() + _mm256_sad_epu8() to
_mm256_movemask_epi8() + __builtin_popcount().
This will allow adjusting the I/O size above 16KiB.
* configure.ac: Align check with routines used in wc_avx2.c.
* src/show-date.{h,c}: Declaration and definition of show_date.
* src/du.c: Wse the common show_date instead of the previous local
function.
* src/date.c: Wse the common show_date via a wrapper show_date_helper.
* src/local.mk: Corresponding adjustments.
* src/cp.c: Add the entries for the --update=none-fail option.
* tests/mv/update.sh: Add a test case.
* NEWS: Mention the bug fix.
Fixes https://bugs.gnu.org/70727
* gnulib: Update to support bootstrapping with python by default.
* bootstrap: Sync with gnulib.
* cfg.mk: Don't force python implementation with `make world`,
rather rely on the auto selection of python if appropriate.
* doc/coreutils.texi (sort invocation): Give a DSU example
for sorting names which may have a variable number of fields.
Addresses https://bugs.gnu.org/70532
* cfg.mk: Add a new "world" default target so that one
can bootstrap (using the python implementation), configure,
and make, by using `make -f cfg.mk`.
* gnulib: Update to latest primarily to test the
bootstrap python implementation which is now in beta test.
* README-hacking: Document the `make -f cfg.mk` shortcut.
Problem reported by Ionut Nicula in:
https://bugs.gnu.org/70477
* src/tail.c (tail_bytes): Do not loop forever on commands
like 'tail -c 4096 /dev/zero'.
* tests/tail/tail-c.sh: Test this fix.
* src/join.c (main): s/field/file/ in the error message
for -a and -v, introduced in TEXTUTILS-1_13-24-g6f63d53e1.
Reported at https://bugs.debian.org/1068864
* src/cat.c (main):
Improve test for when copying will exhaust the output device.
Do not rely on st_size, which is unreliable in /proc.
Use lseek instead; this is good enough here.
* tests/cat/cat-self.sh: Test the relaxation of the heuristic
for self-copying.
od was seen to abort() on glibc on ia64 and m68k with the error:
Fatal glibc error: printf_fp.c:501 (__printf_fp_buffer_1):
assertion failed:
cy == 1 || (p.frac[p.fracsize - 2] == 0 && p.frac[0] == 0)
* tests/od/od-multiple-t.sh: Avoid outputting long double floats
to avoid undefined behavior. 'float' and 'double' are standardized
by IEEE 754 (except on Linux/m68k) and don't have undefined values.
* tests/misc/numfmt.pl: Verify that printf field width specs
count characters and not bytes before enabling locale tests.
This was seen on FreeBSD 14.0 and Solaris 11 OpenIndiana.
Reported by Bruno Haible
* src/ls.c (print_dir): readdir() on FreeBSD 14 was
seen to pass ENOENT through. ENOENT in this context
means "Directory unlinked but still open".
Reported by Bruno Haible with tests/ls/removed-directory.sh
There is a mismatch between isblank() used by tr and c32isblank() now
used by uniq on Solaris 11 OpenIndiana. isblank() was seen to return
true for non breaking space, while c32isblank() returned false.
Interestingly on Solaris, non breaking space is considered a blank
character, and isblank() and c32isblank() honor this in all locales.
* tests/uniq/uniq.pl: Adjust the blank check to use join(1) rather than
tr(1), as join uses the same blank determination routines as uniq(1).
This issue was introduced in commit v8.19-145-g24ebca6
* src/copy.c (copy_internal): On systems that don't support ACLs,
the fallback default chmod done on directories should maintain
the set-group-ID, as that's generally auto-set by the system.
* NEWS: Mention the fix.
Reported by Bruno Haible on Alpine (with tests/cp/preserve-mode.sh)
* tests/misc/numfmt.pl: Some systems with the fr_FR.UTF-8
locale installed, do not have a thousands grouping character defined.
In this case we skip the locale tests which depend on a non empty
grouping character.
* tests/chmod/symlinks.sh: The count of adjusted modes was
one more on systems where symlink modes can be adjusted.
Therefore only include the non symlinks in the count.
* src/chown-core.h (emit_from_option_description): The conditional
string composition here caused issues for translators.
Instead move to a more general description ...
(src/chown.c (usage): ... here.
Fixes https://bugs.gnu.org/69985
* tests/chmod/symlinks.sh: Ensure this new test is immune
to setgid directories by resetting modes with =777 rather than 777.
Also output more debugging in all failure cases.
