+ * NEWS: Record release date.
+
+2022-04-15 Pádraig Brady <P@draigBrady.com>
+
+ doc: avoid unicode errors in texi conversion
+ Avoid "Unicode character U+#1 not supported, sorry" error
+ when converting from texi to dvi or pdf.
+
+ * doc/coreutils.texi (tr invocation): Avoid the @U{XXXX}
+ texi representation, as even though info and html can represent
+ these characters directly, there are conversion errors
+ for pdf and dvi. Instead use the more abstract shell
+ $'\uXXXX' representation.
+
+2022-04-14 Pádraig Brady <P@draigBrady.com>
+
+ build: copy: fix build on macos 10.12
+ * src/copy.c (copy_reg): Handle the case where CLONE_NOOWNERCOPY
+ is not defined.
+ Reported by Jeffrey Walton
+
+2022-04-13 Pádraig Brady <P@draigBrady.com>
+
+ tail: detect closed stdout on Solaris
+ * src/tail.c (check_output_alive): Use poll() on Solaris.
+ Also handle POLLHUP, which Solaris returns in this case.
+ * tests/tail-2/pipe-f.sh: Use `head -n2` rather than `sed 2q`
+ as Solaris sed does not exit in this case.
+ * NEWS: Mention the improvement.
+ Reported by Bruno Haible.
+
+ maint: syntax-check: fix preprocessor indentation
+ * gl/lib/targetdir.h: Keep '#' at start of line.
+
+2022-04-13 Paul Eggert <eggert@cs.ucla.edu>
+
+ cp,mv,install: omit an ‘inline’
+ * gl/lib/targetdir.c (target_directory_operand):
+ Omit unnecessary ‘inline’.
+
+ cp,mv,install: improve EACCES targetdir messages
+ This improves on the fix for --target-directory diagnostics bugs on
+ Solaris 11. Problem reported by Bruno Haible and Pádraig Brady; see:
+ https://lists.gnu.org/r/coreutils/2022-04/msg00044.html
+ Also, omit some unnecessary stat calls.
+ * gl/lib/targetdir.c (target_directory_operand): If !O_DIRECTORY,
+ do not bother calling open if stat failed with errno != EOVERFLOW.
+ Rename is_a_dir to try_to_open since that’s closer to what it means.
+ If the open failed with EACCES and we used O_SEARCH, look at stat
+ results to see whether errno should be ENOTDIR for better diagnostics.
+ Treat EOVERFLOW as an “I don’t know whether it’s a directory and
+ there’s no easy way to find out” rather than as an error.
+
+ cp,mv,install: avoid excess stat calls on non-GNU
+ * gl/lib/targetdir.c (target_directory_operand): New arg ST.
+ All callers changed.
+ * src/cp.c (do_copy):
+ * src/mv.c (main):
+ Avoid unnecessary stat call if target_directory_operand already
+ got the status.
+
+ cp,mv,install: modularize targetdir
+ Move target directory code out of system.h to a new targetdir module.
+ This doesn’t change functionality.
+ * bootstrap.conf (gnulib_modules): Add targetdir.
+ * src/cp.c, src/install.c, src/mv.c: Include targetdir.h.
+ * src/system.h (must_be_working_directory, target_directory_operand)
+ (targetdir_dirfd_valid): Move from here ...
+ * gl/lib/targetdir.c, gl/lib/targetdir.h, gl/modules/targetdir:
+ ... to these new files.
+
+2022-04-13 Pádraig Brady <P@draigBrady.com>
+
+ cp,mv,install: avoid EACCES with non directory destination
+ * src/system.h (target_directory_operand): Also check with stat()
+ on systems with O_SEARCH, to avoid open("file", O_SEARCH|O_DIRECTORY)
+ returning EACCES rather than ENOTDIR, which was seen on Solaris 11.4
+ when operating on non dirs without execute bit set.
+ * NEWS: Remove related bug entry, as that issue was only introduced
+ after coreutils v9.0 was released.
+ Reported by Bruno Haible.
+
+ sync: support syncing files on cygwin
+ * src/sync.c (sync_arg): Similarly to AIX, Cygwin 2.9.0
+ was seen to need write access to have permission to sync a file.
+
+ tests: cygwin: handle ENOENT from execvp(".")
+ * tests/misc/env.sh: Verify with another command that
+ execvp() doesn not return ENOENT, before testing the
+ exit code from the command in question.
+ * tests/misc/nice-fail.sh: Likewise.
+ * tests/misc/stdbuf.sh: Likewise.
+ * tests/misc/timeout-parameters.sh: Likewise.
+
+ tests: env-S.pl: unset cygwin hardwired env vars
+ * tests/misc/env-S.pl: Unset SYSTEMROOT and WINDIR.

+
+ tests: md5sum: fix false failures on cygwin
+ * tests/misc/md5sum-newline.pl: Avoid binary '*' tags when
+ comparing checksums.
+ * tests/misc/md5sum-bsd.sh: Avoid binary '*' tags so that we correctly
+ trigger the ambiguity test.
+ Reported by Bruno Haible
+
+2022-04-11 Pádraig Brady <P@draigBrady.com>
+
+ tests: b2sum.sh: fix false failure on cygwin
+ * tests/misc/b2sum.sh: Avoid binary '*' tags when comparing checksums.
+ Reported by Bruno Haible
+
+ tests: dircolors.pl: avoid false failure with TERM=dumb
+ * tests/Coreutils.pm: Ensure an unset $TERM env var,
+ which is required on perl 5.22.2 on Solaris 11 OpenIndiana at least,
+ where TERM was being reset to 'dumb'.
+ Reported By Bruno Haible.
+
+ tests: printf-mb.sh: fix false failure with french translations
+ * tests/misc/printf-mb.sh: As per commit 04148c99c,
+ adjust non C warnings before comparison, to those of LC_MESSAGES=C.
+ Reported by Adam Sampson
+
+2022-04-10 Pádraig Brady <P@draigBrady.com>
+
+ tests: stty.sh: skip on systems without perl
+ * init.cfg (stty_reversible_init_): Add require_perl_
+ to ensure we skip rather than error, without perl.
+
+2022-04-09 Pádraig Brady <P@draigBrady.com>
+
+ cp,mv,install: avoid opening non directory destination
+ commit v9.0-66-ge2daa8f79 introduced an issue, for example
+ where cp could hang when overwriting a destination fifo,
+ when it would try to open() the fifo on systems
+ like Solaris 10 that didn't support the O_DIRECTORY flag.
+
+ This is still racy on such systems, but only in the
+ case where a directory is replaced by a fifo in
+ the small window between stat() and open().
+
+ * src/system.h (target_directory_operand): On systems without
+ O_DIRECTORY, ensure the file is a directory before attempting to open().
+ * tests/cp/special-f.sh: Protect cp with timeout(1),
+ as cp was seen to hang when trying to overwrite an existing fifo.
+ * NEWS: Mention the bug fix.
+
+2022-04-09 Pádraig Brady <P@draigBrady.com>
+
+ doc: install --compare: clarify mode of operation
+ * doc/coreutils.texi (install invocation): For the --compare option,
+ clarify that the ownership or permissions of the source files don't
+ matter. Also don't imply --owner or --group need to be specified
+ for --compare to be effective.
+ * src/install.c (usage): Add more detail on what's being compared.
+ Fixes https://bugs.gnu.org/50889

+
+2022-04-03 Pádraig Brady <P@draigBrady.com>

+ * NEWS: Move description from "Changes in behavior"
+ to "New features".
+
+2022-04-03 Pádraig Brady <P@draigBrady.com>
+
+ ls: avoid expensive capability lookup by default
+ Lookup of file-based capabilities adds 30% overhead to the common
+ case of ls --color usage. Since the use of file capabilities is
+ very rare, it doesn't make sense to pay this cost in the common
+ case. It's better to use getcap to inspect capabilities, and the
+ following run shows only 8 files using capabilities on my fedora
+ 35 distro (14 years after the feature was introduced to the linux
+ kernel).
+
+ $ getcap -r /
+ /usr/bin/arping = cap_net_raw+p
+ /usr/bin/clockdiff = cap_net_raw+p
+ /usr/bin/gnome-keyring-daemon = cap_ipc_lock+ep
+ /usr/bin/gnome-shell = cap_sys_nice+ep
+ /usr/bin/newgidmap = cap_setgid+ep
+ /usr/bin/newuidmap = cap_setuid+ep
+ /usr/sbin/mtr-packet = cap_net_raw+ep
+ /usr/sbin/suexec = cap_setgid,cap_setuid+ep
+
+ * src/dircolors.hin: Set "CAPABILITY" to "00", to indicate unused.
+ * src/ls.c: Set the default C_CAP color to not colored.
+ * NEWS: Mention the change in behavior.
+
+2022-04-03 Ville Skyttä <ville.skytta@iki.fi>
+
+ dircolors: colorize backup files with bright black
+ * src/dircolors.hin: Add patterns for suffixes for "backup files".
+ The color used is so they stand out less than non-backup files,
+ and bright black works well on both light and dark backgrounds.
+ * THANKS.in: Remove duplicate.
+ Fixes https://bugs.gnu.org/54521
+
+2022-03-29 Pádraig Brady <P@draigBrady.com>
+
+ doc: join: clarify that -e only effective for -12jo fields
+ * src/join.c (usage): Clarify that -e is not sufficient
+ to enable output of missing fields from one of the inputs.
+ Rather the -12jo options are required to explicitly
+ enable output of those fields.
+ Fixes https://bugs.gnu.org/54625

+
+2022-03-19 Pádraig Brady <P@draigBrady.com>

+
+ doc: test: clarify that -rwx don't just check perm bits
+ * src/test.c (usage): State that -rwx is determined by
+ user access, rather than permission bits.
+ * doc/coreutils.texi (Access permission tests): Likewise.
+ * man/test.x [SEE ALSO]: access(2).
+ Fixes https://bugs.gnu.org/54338

+
+ stat: only automount with --cached=never
+ Revert to the default behavior before the introduction of statx().

+
+ Fixes https://bugs.gnu.org/54287
+
+2022-03-07 Rohan Sable <rsable@redhat.com>
+
+ ls: avoid triggering automounts
+ statx() has different defaults wrt automounting
+ compared to stat() or lstat(), so explicitly
+ set the AT_NO_AUTOMOUNT flag to suppress that behavior,
+ and avoid unintended operations or potential errors.
+
+ * src/ls.c (do_statx): Pass AT_NO_AUTOMOUNT to avoid this behavior.
+ * NEWS: Mention the change in behavior.
+ Fixes https://bugs.gnu.org/54286
+
+2022-03-07 Pádraig Brady <P@draigBrady.com>

+
+2022-02-24 Pádraig Brady <P@draigBrady.com>
+
+ tests: improve compat with macOS
+ * tests/misc/wc-nbsp.sh: Only the en_US.iso8859-1 form
+ is accepted on macOS 10.15.7 at least. GNU/Linux also
+ accepts ISO-8859-1 (and canonicalizes the charmap to this).
+
+2022-02-23 Paul Eggert <eggert@cs.ucla.edu>
+
+ dd: counts ending in "B" now count bytes
+ This implements my suggestion in Bug#54112.
+ * src/dd.c (usage): Document the change.
+ (parse_integer, scanargs): Implement the change.
+ Omit some now-obsolete checks for invalid flags.
+ * tests/dd/bytes.sh: Test the new behavior, while retaining

+
+ doc: use bold style for man page references
+ It's more common to use bold style than not,
+ for references to other man pages.
+ Ideally each man page renderer would highlight references,
+ but currently some rely on styles in the page itself.
+
+ * man/help2man: Implement a --bold-refs option that
+ will mark up references like "name(1)" with bold
+ style around the "name" component.
+ * man/local.mk: Pass --bold-refs to our help2man unless disabled.
+ * configure.ac: Add a --disable-bold-man-page-references option.

+
+ dircolors: speed up processing of TERM entries
+ * src/dircolors.c (main): Avoid glob matching
+ when we've already matched in a group of {COLOR,}TERM entries.
+
+2022-02-15 Pádraig Brady <P@draigBrady.com>
+
+ dircolors: consider COLORTERM as well as TERM env vars
+ COLORTERM is an environment used usually to expose truecolor support in
+ terminal emulators. Therefore support matches on that in addition
+ to TERM. Also set the default COLORTERM match pattern so that
+ we apply colors if COLORTERM is any value.
+
+ This implicitly supports a terminal like "foot"
+ without a need for an explicit TERM entry.
+
+ * NEWS: Mention the new feature.
+ * src/dircolors.c (main): Match COLORTERM like we do for TERM.
+ * src/dircolors.hin: Add default config to match any COLORTERM.
+ * tests/misc/dircolors.pl: Add test cases.
+
+2022-02-14 Paul Eggert <eggert@cs.ucla.edu>
+
+ tr: mention multibyte problem in man page
+ * man/tr.x: Document tr problem.
+
+ tr: improve multibyte etc. doc
+ Problem reported by Dan Jacobson (Bug#48248).
+ * doc/coreutils.texi (tr invocation): Improve documentation for
+ tr's failure to support multibyte characters POSIX-style.
+ * doc/coreutils.texi (tr invocation), src/tr.c (usage):
+ Use terminology closer to POSIX's.
+
+2022-02-13 Pádraig Brady <P@draigBrady.com>
+
+ dircolors: add --print-ls-colors to display colored entries
+ * NEWS: Mention the new feature.
+ * doc/coreutils.texi (dircolors invocation): Describe the new
+ --print-ls-colors option.
+ * src/dircolors.c (print_ls_colors): A new global to select
+ between shell or terminal output.
+ (append_entry): A new function refactored from dc_parse_stream()
+ to append the entry in the appropriate format.
+ (dc_parse_stream): Adjust to call append_entry().
+ * tests/misc/dircolors.pl: Add test cases.
+
+2022-02-13 Pádraig Brady <P@draigBrady.com>
+
+ chown,chgrp: reinstate numeric id output in -v messages
+ since gnulib commit ff208d546a,
+ related to coreutils commit v9.0-143-gabde15969
+ we no longer maintain numeric IDs through chopt->{user,group}_name.
+ Therefore we need to adjust to ensure tests/chown/basic.sh passes.
+
+ * src/chown-core.c (uid_to_str, gid_to_str): New helper functions
+ to convert numeric id to string.
+ (change_file_owner): Use the above new functions to pass
+ numeric ids to describe_change().
+
+2022-02-13 Paul Eggert <eggert@cs.ucla.edu>
+
+ sort: fix several version-sort problems
+ This also affects ls -v in some corner cases.
+ Problems reported by Michael Debertol <https://bugs.gnu.org/49239>.
+ While looking into this, I spotted some more areas where the
+ code and documentation did not agree, or where the documentation
+ was unclear. In some cases I changed the code; in others
+ the documentation. I hope things are nailed down better now.
+ * doc/sort-version.texi: Distinguish more carefully between
+ characters and bytes. Say that non-identical strings can
+ compare equal, since they now can. Improve readability in
+ various ways. Make it clearer that a suffix can be the
+ entire string.
+ * src/ls.c (cmp_version): Fall back on strcmp if filevercmp
+ reports equality, since filevercmp is no longer a total order.
+ * src/sort.c (keycompare): Use filenvercmp, to treat NULs correctly.
+ * tests/misc/ls-misc.pl (v_files):
+ Adjust test to match new behavior.
+ * tests/misc/sort-version.sh: Add tests for stability,
+ and for sorting with NUL bytes.
+
+ build: update gnulib submodule to latest
+
+2022-02-12 Pádraig Brady <P@draigBrady.com>
+
+ doc: avoid using "[" is URLS in --help output
+ * src/system.h (emit_ancillary_info): While supported if entered
+ manually, the "[" character is not highlighted as part of a
+ URL by default in terminals, so avoid using it.
+ Addresses https://bugs.gnu.org/53946
+
+ doc: adust --help, --version alignment
+ * src/system.h: Adjust the alignment of the --help
+ and --version option descriptions, to start at column 21.
+ This better aligns with the descriptions of most commands,
+ and also aligns with the minimum column a description must
+ start at to ensure a blank line is not output when a description
+ follows an option on a line by itself.
+
+ doc: rmdir: improve --help formatting
+ * src/rmdir.c (usage): Move description to column 21,
+ so that a --long-option on its own line without a
+ trailing description, doesn't have an erroneous blank
+ line inserted between the option and description.
+ Also group descriptions with blank lines rather than indents,
+ so that man pages don't have erroneous blank lines
+ added within the description.
+ Addresses https://bugs.gnu.org/53946
+
+ doc: ls: reference dircolors(1) from --help
+ * src/ls.c (usage): s/dircolors/dircolors(1)/.
+ * man/ls.x [SEE ALSO]: Reference dircolors(1).
+ Addresses https://bugs.gnu.org/53946
+
+ doc: ls: improve --help formatting
+ * src/ls.c (usage): Use blank lines to group multi-line
+ option descriptions, rather than indenting.
+ This results in more consistent alignment of descriptions,
+ and also avoids erroneous new lines in generated in man pages.
+ Addresses https://bugs.gnu.org/53946
+
+2022-02-08 Paul Eggert <eggert@cs.ucla.edu>
+
+ doc: improve version-sort doc
+ * doc/coreutils.texi, doc/sort-version.texi:
+ Capitalize “Coreutils”.
+ * doc/sort-version.texi: Don’t emphasize natural sort so much,
+ since Coreutils has just version sort.
+ Use the term “lexicographic” instead of “alphabetic” or “standard”.
+ Suggest combining ‘V’ with ‘b’, and show why ‘b’ is needed.
+ Use shorter titles for sections, as GNU Emacs displays info poorly
+ when titles are too long to fit in a line.
+ Use @samp instead of @code for samples of data.
+ Do not use @samp{@code{...}}; @samp{...} should suffice and
+ double-nesting looks bad with Emacs.
+ Omit blank lines in examples that would not be present
+ in actual shell sessions.
+ Quote with `` and '', not with " or with '.
+ Mention dpkg --compare-versions more prominently.
+ Don’t rely on "\n" being equivalent to "\\n" in shell args.
+ Prefer Unicode name for hyphen-minus.

+
+ doc: fix somewhat ambiguous date format representation
+ * doc/coreutils.texi (date invocation): Remove @var{...} usage,
+ as that capitalizes in the representation and thus somewhat
+ ambiguates the format wrt Month and Minute. This also avoids

+ cksum: use more exact selection of digest algorithms
+ Use more constrained argument matching
+ to improve forward compatibility and robustness.
+
+ For example it's better that `cksum -a sha3` is _not_
+ equivalent to `cksum -a sha386`, so that a user
+ specifying `-a sha3` on an older cksum would not be surprised.
+
+ Also argmatch() is used when parsing tags from lines like:
+ SHA3 (filename) = abcedf....
+ so it's more robust that older cksum instances to fail
+ earlier in the parsing process, when parsing output from
+ possible future cksum implementations that might support SHA3.
+
+ * src/digest.c (algorithm_from_tag): Use argmatch_exact()

+ maint: avoid strncat warning on GCC
+ GCC 10.1.1 without optimization gives:
+
+ error: ‘strncat’ argument 2 declared attribute ‘nonstring’
+ [-Werror=stringop-overflow=]
+ strncat (comment, UT_ID (utmp_ent), utmpsize);
+
+ Note the strncat man page says that:
+ "src does not need to be null-terminated
+ if it contains n or more bytes."
+ And the POSIX spec says that the second (source) parameter
+ is an array not a string.
+ So I think it's incorrect for strncat to require src be a string type.
+ This constraint seems to be being added to the gcc builtin strncat,
+ as specifiying -fno-builtin also avoids the warning.
+ Note specifying any optimization level also avoids the warning.
+
+ * src/who.c (make_id_equals_comment): Avoid the issue by using
+ stpcpy + stzncpy, instead of strcpy + strncat.

+
+ ls: use statx instead of stat when available
+ statx allows ls to indicate interest in only certain inode metadata.
+ This is potentially a win on networked/clustered/distributed
+ file systems. In cases where we'd have to do a full, heavyweight stat()
+ call we can now do a much lighter statx() call.
+
+ As a real-world example, consider a file system like CephFS where one
+ client is actively writing to a file and another client does an
+ ls --color in the same directory. --color means that we need to fetch
+ the mode of the file.
+
+ Doing that with a stat() call means that we have to fetch the size and
+ mtime in addition to the mode. The MDS in that situation will have to
+ revoke caps in order to ensure that it has up-to-date values to report,
+ which disrupts the writer.
+
+ This has a measurable affect on performance. I ran a fio sequential
+ write test on one cephfs client and had a second client do "ls --color"
+ in a tight loop on the directory that held the file:
+
+ Baseline -- no activity on the second client:
+
+ WRITE: bw=76.7MiB/s (80.4MB/s), 76.7MiB/s-76.7MiB/s (80.4MB/s-80.4MB/s),
+ io=4600MiB (4824MB), run=60016-60016msec
+
+ Without this patch series, we see a noticable performance hit:

+ stat: don't explicitly request file size for filenames
+ When calling 'stat -c %N' to print the filename, don't explicitly
+ request the size of the file via statx(), as it may add overhead on
+ some filesystems. The size is only needed to optimize an allocation
+ for the relatively rare case of reading a symlink name, and the worst
+ effect is a somewhat-too-large temporary buffer may be allocated for
+ areadlink_with_size(), or internal retries if buffer is too small.
+
+ The file size will be returned by statx() on most filesystems, even
+ if not requested, unless the filesystem considers this to be too
+ expensive for that file, in which case the tradeoff is worthwhile.
+
+ * src/stat.c: Don't explicitly request STATX_SIZE for filenames.

+ ln: avoid directory hard-link races
+ Previously, 'ln A B' did 'stat("B"), lstat("A"), link("A","B")'
+ where the stat and lstat were necessary to avoid hard-linking

+ dd: fix nocache regions passed to posix_fadvise()
+ Previously with oflag=direct the call to invalidate_cache()
+ was not passed to the kernel, as it was less than a page size,
+ and a subsequent call was not made to invalidate the pending space.
+ Similarly with oflag=nocache the pending space at EOF was
+ not invalidated. Even though these amount to only a single page
+ in the page cache it can be significant. For example on
+ XFS before kernel patch v4.9-rc1-4-g0ee7a3f, O_DIRECT files
+ would have been read inefficiently if any pages were cached,
+ even if they were already synced to storage.
+
+ * src/dd.c (i_nocache_eof, o_nocache_eof): New bools used
+ to control when we want invalidate_cache(,0) to clear to EOF.
+ (cache_round): Use IO_BUFSIZE (currently 132KiB) to minimize
+ calls to the relatively expensive advise function, rather
+ than page_size. This also makes it clear that while the
+ kernel function operates on pages, this size is chosen for
+ performance reasons.
+ (invalidate_cache): Refactor to share more code between
+ input and output paths. Use i_nocache_eof and o_nocache_eof
+ rather than proxying off max_records. Ensure we
+ invalidate full pages when clearing to EOF as the kernel
+ will ignore any non complete pages. Fix the offset used
+ for the output path.
+ (dd_copy): Invalidate the cache of the input after the
+ offset is updated, for consistency and so we don't try to
+ invalidate before the start of the file. When we read
+ EOF on input, set flags so that we invalidate to EOF.
+ (main): Invalidate to EOF in more cases, by depending

+ df: avoid stat() for dummy file systems with -l
+ When systemd is configured to automount a remote file system - see
+ 'man systemd.automount(5)', then the mount point is initially
+ mounted by systemd with the file system type "autofs".
+ When the resource is used later on, then the wanted file system is
+ mounted over that mount point on demand.

+ maint: avoid spurious "make distcheck" failure
+ When the generated file, doc/constants.texi, happens to be older than

+ contents change. This is due to way that rule is careful to update
+ the file, to avoid provoking a pointless rerunning of makeinfo.
+
+ Note that this does not happen when one first runs "make distclean",
+ as recommended in README-release. However, I sometimes run it as
+ a more-rigorous "make check", and shouldn't have to manually run
+ "make distclean" first, in that case.

+ * src/expand-common.c (next_file): We're dependent on calling
+ this function with NULL to initialize things appropriately.

+ split: ensure input is processed when filters exit early
+ commit v8.25-4-g62e7af0 introduced the issue as it
+ broke out of the processing loop irrespective of
+ the value of new_file_flag which was used to indicate
+ a finite number of filters or not.
+
+ For example, this ran forever (as it should):
+ $ yes | split --filter="head -c1 >/dev/null" -b 1000
+ However this exited immediately due to EPIPE being propagated
+ back through cwrite and the loop not considering new filters:
+ $ yes | split --filter="head -c1 >/dev/null" -b 100000
+
+ Similarly processing would exit early for a bounded number of
+ output files, resulting in empty data sent to all but the first:
+ $ truncate -s10T big.in
+ $ split --filter='head -c1 >$FILE' -n 2 big.in
+ $ echo $(stat -c%s x??)
+ 1 0
+
+ I was alerted to this code by clang-analyzer,
+ which indicated dead assigments, which is often
+ an indication of code that hasn't considered all cases.
+
+ * src/split.c (bytes_split): Change the last condition in
+ the processing loop to also consider the number of files
+ before breaking out of the processing loop.
+ * tests/split/filter.sh: Add a test case.
+ * NEWS: Mention the bug fix.

+ tests: avoid a false failure on OS X 10.5.8
+ * tests/misc/sort-debug-keys.sh: Disparate LC_CTYPE and LC_MESSAGES
+ are not supported, with the result LC_MESSAGES=C is used throughout.
+ Therefore just set LC_ALL in the test, and normalize the message
+ variants with sed.
+ Reported and tested by J Rogowsky.
