	version 8.32
	* NEWS: Record release date.

2020-03-04  Pádraig Brady  <P@draigBrady.com>

	tests: don't rely on system env(1) being present
	* tests/misc/env-S.pl: `env -i env` will call the system env
	due to the path being cleared, so pass the absolute path
	of our env binary under test to avoid that.  This was seen
	to be an issue on Guix where /usr/bin/env was not available.

	basenc: avoid undefined behaviour in z85 processing
	* src/basenc.c (z85_decode_ctx_init): Ensure we're working
	with unsigned, as otherwise ubsan triggers with:
	  src/basenc.c:767:18: runtime error: signed integer overflow:
	  43 * 52200625 cannot be represented in type 'int'
	(z85_encode): Likewise to avoid the usban error:
	  src/basenc.c:630:26: runtime error:
	  left shift of 134 by 24 places cannot be represented in type 'int'

2020-03-01  Pádraig Brady  <P@draigBrady.com>

	tests: avoid a false failure on OpenIndiana 11
	* tests/misc/timeout-parameters.sh: Split the large timeout
	handling to ...
	* tests/misc/timeout-large-parameters.sh: ... here, so that
	the 3 second delay is contained in its own test, and if
	the test is skipped due invalid handling within timeout(1),
	it will be more apparent.
	Also adjust the check so we skip whenever the kernel timer
	fires immediately, to handle the buggy OpenIndiana 11 kernel also.
	Reported by Bruno Haible.

	tests: avoid a hang on GNU/Hurd from 2019
	* tests/du/8gb.sh: Add a timeout around:
	`dd bs=1 seek=8G of=big < /dev/null`

	tests: use bash in some scripts to avoid false failures
	* init.cfg (require_bash_as_SHELL_): A new function to replace
	SHELL for the current test, with bash if available.
	This is useful on OpenIndiana 11 where /bin/sh was seen
	to have races in handling of SIGPIPE.
	* tests/misc/seq-epipe.sh: Use the new function to enforce bash.
	* tests/misc/env-signal-handler.sh: Likewise.
	Reported by Bruno Haible

	tests: improve test coverage for ls stat checks
	* tests/ls/stat-free-color.sh: Check for the availability
	of various stat calls individually, and add statx() and fstatat64()
	to the list to check.  Fix the stat counting logic to
	ignore lines like "+++ exited with 0 +++".
	* tests/ls/stat-free-symlinks.sh: Check syscalls other than stat().

2020-03-01  Bruno Haible  <bruno@clisp.org>

	tests: enable 4 more tests to be executed on FreeBSD
	* init.cfg (gcc_shared_libs_): New variable.
	(gcc_shared_): Use it, instead of hardcoding -ldl.
	(require_gcc_shared_): Determine the suitable value
	for gcc_shared_libs_.

2020-02-29  Pádraig Brady  <P@draigBrady.com>

	tests: fix incorrect `|| fail` pattern in tests
	* tests/ls/stat-free-symlinks.sh: s/|| fail/|| fail=1/.
	* tests/misc/tee.sh: Likewise.
	* tests/touch/relative.sh: Likewise.
	* cfg.mk (sc_prohibit_or_fail): A new syntax-check to avoid this.

2020-02-29  Pádraig Brady  <P@draigBrady.com>

	tests: avoid false failures on darwin 19.2.0
	With these adjustments, all tests pass on macOS Catalina.

	* tests/dd/sparse.sh: Adjust so that systems like apfs that
	don't create holes < 16 MiB do not fail erroneously.
	* tests/touch/trailing-slash.sh: Darwin was seen to dereference
	symlinks to files when given a trailing slash, so avoid
	that particular case.

2020-02-29  Bruno Haible  <bruno@clisp.org>

	tests: fix test failure on FreeBSD 12
	* tests/misc/csplit-io-err.sh: Limit the effect of the fwrite
	override to streams != stderr, as fwrite is in the error() path there.

2020-02-27  Jan Nieuwenhuizen  <janneke@gnu.org>

	build: once again distribute .tar.gz files
	* configure.ac: Reenable distribution of gzip-compressed
	tarballs, for Guix bootstrapping reasons as discussed at:
	https://lists.gnu.org/r/coreutils/2020-02/msg00042.html
	* THANKS.in: Remove me, as now a committer.
	* NEWS (Build-related): Mention this.

2020-02-27  Pádraig Brady  <P@draigBrady.com>

	maint: ensure .deps/ in the project root is ignored by git
	* .gitignore: s|*/.deps/|.deps|

	doc: remove older ChangeLog items
	* Makefile.am: Update the oldest documented version
	to 8.23 which is now about 5 years old.

	ls: issue error message on removed directory
	If the current directory has been removed, then "ls" confusingly
	produced no output and no error message, indistinguishable from
	running on an empty directory.

	* src/ls.c (print_dir): Report ENOENT on GNU/Linux if readdir
	finds no directory entries at all, not even "." or "..",
	and a recheck with the getdents syscall returns ENOENT.
	We recheck with getdents() as POSIX states that
	"The directory entries for dot and dot-dot are optional".
	* tests/ls/removed-directory.sh: New file.
	* tests/local.mk (all_tests): Add new test.
	* NEWS: Mention the change in behavior.
	Reported by Owen Thomas.

2020-02-25  Pádraig Brady  <P@draigBrady.com>

	build: update to latest gnulib
	* bootstrap.conf: Adjust for changes to fchmodat and fchownat,
	which are now separated from chmodat and chownat respectively.

	b2sum: sync better with upstream
	* src/blake2/blake2-impl.h: Sync load16() implementation,
	which doesn't change code generation.
	Also leverage (builtin) memcpy to more efficiently
	move data on little endian systems,
	giving a 2% win with GCC 9.2.1 on an i3-2310M.

	factor: sync longlong.h adjustments from upstream
	* src/longlong.h: Sync changes from:
	https://gmplib.org/repo/gmp/log/tip/longlong.h
	mips64: Provide r6 asm code as default expression yields.
	arm32: Define sub_ddmmss separately for non-thumb (no rsc instruction).
	powerpc: Add "CLOBBER" descriptions for some registers.
	x86: Fix criterion for when to use mulx in umul_ppmm.

	stat,tail: sync file system constants from the linux kernel
	* src/stat.c: Add magic constants for "binderfs", "dma-buf-fs",
	"erofs", "ppc-cmm-fs", and "z3fold".
	* NEWS: Mention the improvement.

	uniq: avoid strcoll() to improve performance and consistency
	strcoll() is only significant to uniq(1) if it returns 0,
	and it generally only does so with buggy locales or mismatched
	locales and data.  Some systems may have strcoll()
	return 0 for equivalent normalized unicode forms,
	but for consistency across platforms strcoll() is avoided.
	The various cases are defined in the new test.
	This is consistent with newer POSIX standards as discussed at:
	https://www.austingroupbugs.net/view.php?id=963

	* src/uniq.c: s/xstrcoll/memcmp/.
	* tests/local.mk: Reference the new test.
	* tests/misc/uniq-collate.sh: Add a new test.
	* NEWS: Mention the change in behavior.
	Fixes https://bugs.gnu.org/38627

2020-02-15  Pádraig Brady  <P@draigBrady.com>

	doc: clarify that '%a' stat format outputs mode bits
	* src/stat.c (usage): Mention permission bits rather than
	"access" so there is no confusion with ACLs etc.
	Also indicate we output the file type with '%A'.
	* doc/coreutils.texi (stat invocation): Likewise.
	Also indicate '%A' is similar to `ls -ld` output.
	Addresses https://bugs.gnu.org/39613

2020-02-10  Pádraig Brady  <P@draigBrady.com>

	tests: fix test for symlink
	* tests/cp/preserve-gid.sh: s/-l/-L/.
	Reported by Kamil Dudka

2020-02-09  Kamil Dudka  <kdudka@redhat.com>

	tests: ensure tests/cp/preserve-gid.sh works with single binary
	* tests/cp/preserve-gid.sh: If configured with --enable-single-binary
	copy the coreutils single binary, instead of the cp one-line launcher.

	Discussed at https://bugzilla.redhat.com/1800597
	Fixes https://bugs.gnu.org/39485

2020-02-09  Pádraig Brady  <P@draigBrady.com>

	maint: avoid syntax-check failure in previous commit
	* configure.ac: Restrict lines to 80 chars.

2020-02-09  Jim Meyering  <meyering@fb.com>

	build: suppress new FP warning from gcc-10.0.1
	* configure.ac (GNULIB_WARN_CFLAGS): Add -Wno-return-local-addr
	to avoid FP warning about careadlinkat.c. Discussed starting in
	https://lists.gnu.org/r/coreutils/2020-02/msg00006.html

2020-02-04  Pádraig Brady  <P@draigBrady.com>

	build: update to latest gnulib
	Pick up recent build fixes to avoid sysctl.h inclusion on glibc systems,
	restrict the max file size supported by read-file to PTRDIFF_MAX,
	and to avoid a -Werror=unused failure in test-canonicalize.

	tests: avoid false failure due to varying /proc/kallsyms
	* tests/cp/proc-short-read.sh: Switch to using /proc/cpuinfo,
	rather than /proc/kallsyms which was seen to vary in some cases.
	Fixes https://bugs.gnu.org/39357

2020-02-04  Pádraig Brady  <P@draigBrady.com>

	rmdir: fix --ignore-fail-on-non-empty with permissions errors
	Since v6.10-21-ged5c4e7 `rmdir --ignore-fail-on-non-empty`
	had reversed the failure status for directories that failed
	to be removed for permissions reasons.  I.E. it would have
	returned a failure status for such non empty dirs, and vice versa.

	* src/rmdir.c (errno_may_be_non_empty): Rename from the
	more confusing errno_may_be_empty(), and remove the EEXIST
	case (specific to Solaris), which is moot here since
	handled in errno_rmdir_non_empty().
	(ignorable_failure): Fix the logic error so that
	_non_ empty dirs are deemed to have ignorable failures.
	(main): Fix clobbering of errno by is_empty_dir().
	(remove_parents): Likewise.
	* tests/rmdir/ignore.sh: Add a test case.
	* THANKS.in: Add reporter who fixed the errno handling.
	* NEWS: Mention the bug fix.
	Fixes https://bugs.gnu.org/39364

2020-02-03  Pádraig Brady  <P@draigBrady.com>

	build: avoid vector performance warnings in randperm
	* configure.ac: Add -Wno-vector-operation-performance to suppress the
	following gcc-9.2 error in gl/lib/randperm.c:
	  error: vector operation will be expanded piecewise

	build: avoid including sysctl.h on glibc
	* src/uname.c: Avoid unneeded header with GLIBC,
	which has been deprecated since glibc-2.30.
	* src/uptime.c: Likewise.

	ls: support --time=creation to show/sort birth time
	* src/ls.c (usage): Reorganize help for --time,
	and add description for --time=birth.
	(do_statx): Store btime in mtime if available.
	(get_stat_btime): A new function to read the creation time
	from the appropriate stat structure member.
	(cmp_btime): A new function to compare birth time.
	(print_long_format): Output '?' when birth time unavailable.
	* doc/coreutils.texi: Document --time={birth,creation}.
	* tests/local.mk: Reference the new test.
	* tests/ls/birthtime.sh: Add a new test.
	* NEWS: Mention the new feature.

2020-01-30  Chris Meyering  <christophe.meyering@gmail.com>

	build: rearrange yes(1) code to prevent GCC 10 warning
	* src/yes.c (main): Convert for loop to do-while in order to indicate
	that the loop will be run at least once.
	This avoids the following warning after the second loop:
	src/yes.c:110:20: error: writing 1 byte into a region of size 0

2020-01-01  Emil Engler  <me@emilengler.com>

	maint: add lib/iconv_open-zos.h to .gitignore
	* .gitignore: Add file newly generated by gnulib commit 49e78fc

	build: auto enable use of openssl with >= version 3
	* configure.ac: Set --with-openssl=auto-gpl-compat as the default,
	so that openssl is used for md5sum etc., with openssl >= 3,
	which is newly licensed under ASL v2.
	* gnulib: Update to include "auto-gpl-compat" support.

	maint: adjust to split out xstrtol-error gnulib module
	* bootstrap.conf: Depend on the new module split from xstrtol.
	* src/df.c: Include "xstrtol-error.h" for xstrtol_fatal.
	* src/du.c: Likewise.
	* src/ls.c: Likewise.

	chcon: do not validate security context if SELinux is disabled
	* src/chcon.c (main): Skip call of security_check_context()
	in case SELinux is disabled to avoid unnecessary failure.

	Bug: https://bugzilla.redhat.com/1777831

2019-11-12  Paul Eggert  <eggert@cs.ucla.edu>

	doc: remove colon from node name
	* doc/sort-version.texi (Minus/Hyphen and Colon characters):
	Rename from “Minus/Hyphen @samp{-} and Colon @samp{:} characters”,
	as texi2any 6.6 complains about colons in node names.

	shred: modernize documentation
	* doc/coreutils.texi (shred invocation):
	Modernize discussion to today’s technology (Bug#38168).
	* src/shred.c (usage): Omit lengthy duplication of the manual’s
	discussion of file systems and storage devices, as that became out
	of sync with the manual.  Instead, just cite the manual.

2019-10-22  Paul Eggert  <eggert@cs.ucla.edu>

	all: improve parsing of numeric arguments
	This addresses a longstanding "update all callers" FIXME in
	lib/xstrtol.c, by having programs check that numbers do not
	have unknown suffixes.  The problem was also reported for
	'shuf' by my student Maggie Huang while reimplementing a shuf
	subset in Python as an exercise in UCLA Computer Science 35L:
	https://web.cs.ucla.edu/classes/fall19/cs35L/assign/assign3.html
	This patch also improves the portability of the code to unusual
	platforms where ULONG_MAX < SIZE_MAX.
	* NEWS: Mention user-visible changes.
	* src/chgrp.c (parse_group):
	* src/chroot.c (parse_additional_groups):
	* src/du.c (main):
	* src/install.c (get_ids):
	* src/join.c (string_to_join_field):
	* src/ls.c (decode_switches):
	* src/md5sum.c (split_3):
	* src/shuf.c (main):
	* src/sort.c (specify_nthreads):
	* src/uniq.c (size_opt, main):
	Use uintmax_t instead of unsigned long, for portability
	to oddball platforms where unsigned long is not wide enough.
	* src/du.c (main):
	* src/expr.c (mpz_init_set_str) [!HAVE_GMP]:
	* src/install.c (get_ids):
	* src/ls.c (decode_switches):
	* src/mknod.c (main):
	* src/ptx.c (main):
	* src/shuf.c (main):
	* src/sort.c (specify_nmerge, specify_nthreads):
	Reject numbers with suffixes.
	* src/md5sum.c (split_3): Simplify.

	stdbuf: improve size checking
	* bootstrap.conf (gnulib_modules): Add minmax.
	* src/libstdbuf.c: Include stdint.h, minmax.h.
	(apply_mode): Don’t assume SIZE_MAX <= ULONG_MAX.
	Improve checking for invalid sizes.

	shuf: improve randperm overflow checking
	* gl/lib/randperm.c: Include randperm.h first, since it’s the API.
	Include stdint.h, count-leading-zeros.h, verify.h.
	(floor_lg): Rename from ceil_log (which was not actually
	implementing the ceiling!) and implement the floor using
	count_leading_zeros.
	(randperm_bound): Use floor_lg, not ceil_log.  Use uintmax_t
	instead of size_t in case the size gets large on a 32-bit host.
	* gl/modules/randperm (Depends-on): Add count-leading-zeros, stdint.

	build: don’t worry about logical-op checking
	* configure.ac: Remove code tailoring --enable-gcc-warnings
	to GCC 4.7 and earlier, as developers no longer need to worry
	about GCCs that old.

	build: re-enable type-limits checking
	* configure.ac: When --enable-gcc-warnings is used, omit
	-Wno-type-limits.  The need for -Wno-type-limits has passed, now
	that intprops.h uses builtin primitives for GCC 5 and later, given
	that recent GCCs issue type-limits warnings only for non-constant
	expressions.  --enable-gcc-warnings is not intended for use with
	old compilers, so we can drop -Wno-type-limits now.

2019-10-21  Paul Eggert  <eggert@cs.ucla.edu>

	shuf: fix bug with ‘-r -n 0’
	‘shuf -r -n 0 file’ would mistakenly read from standard input.
	Problem reported by my student Jingnong Qu while reimplementing a
	shuf subset in Python as an exercise in UCLA Computer Science 35L:
	https://web.cs.ucla.edu/classes/fall19/cs35L/assign/assign3.html
	* NEWS: Mention the fix.  Also, ASCIIfy a previous item.
	* src/shuf.c (main): Fix bug.
	* tests/misc/shuf.sh: Add a test case for the bug.

	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:

	WRITE: bw=70.4MiB/s (73.9MB/s), 70.4MiB/s-70.4MiB/s (73.9MB/s-73.9MB/s),
	       io=4228MiB (4433MB), run=60012-60012msec

	With this patch series, we gain most of that ground back:

	WRITE: bw=75.9MiB/s (79.6MB/s), 75.9MiB/s-75.9MiB/s (79.6MB/s-79.6MB/s),
	       io=4555MiB (4776MB), run=60019-60019msec

	* src/stat.c: move statx to stat struct conversion to new header...
	* src/statx.h: ...here.
	* src/ls.c: Add wrapper functions for stat/lstat/fstat calls,
	and add variants for when we are only interested in specific info.
	Add statx-enabled functions and set the request mask based on the
	output format and what values are needed.
	* NEWS: Mention the Improvement.

2019-10-03  Paul Eggert  <eggert@cs.ucla.edu>

	truncate: avoid integer-overflow assumptions
	* src/truncate.c (do_ftruncate): Simplify overflow checking,
	and don’t rely on theoretically-nonportable assumptions
	like assuming that OFF_MAX < UINTMAX_MAX.

	numfmt: avoid unlikely integer overflow
	* src/numfmt.c (parse_format_string): Report overflow if
	pad < -LONG_MAX, since that can’t be negated.

	nl: fix integer-overflow bug
	Problem reported by Roland Illig (Bug#37585)
	* src/nl.c (print_lineno): Don’t rely on undefined behavior when
	checking for integer overflow.

	cp: simplify integer overflow checking
	* src/copy.c (sparse_copy): Use INT_ADD_WRAPV instead
	of doing overflow checking by hand.

2019-09-08  Pádraig Brady  <pbrady@fb.com>

	seq: use faster processing for integer steps from 2 to 200
	* src/seq.c: (seq_fast): Accept STEP as a parameter and use that
	to skip the output of generated numbers.
	(main): Relax to using seq_fast for integer steps between 1 and 200.
	For larger steps the throughput was faster using the standard
	incrementing procedure.
	(cmp): Use the equivalent but faster memcmp for equal len strings.
	* tests/misc/seq.pl: Update fast path cases.
	Addresses https://bugs.gnu.org/37241

2019-09-08  Pádraig Brady  <P@draigBrady.com>

	maint: use consistent header ordering and spacing in NEWS
	* NEWS: Move "Changes in behavior" before "New features",
	and ensure there is only a single blank line between sections.

	build: adjust for recent gnulib pthread changes
	Discussed in https://lists.gnu.org/r/coreutils/2019-08/msg00030.html .

	* bootstrap.conf (gnulib_modules): Replace 'pthread' with

	seq: fix superfluous output line
	Under certain circumstances seq prints an extra line when the output
	format has custom format with characters following the printed numbers:

	    $ seq -f "%g " 1000000 1000000
	     1e+06
	     1e+06

	This is due to the "print_extra_number" logic using strings to determine
	whether a 'extra number' is needed, but only one string was trimmed
	when using a custom printf format.

	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.

	tests: avoid false-positive in date-debug test

	Set STATX_* mask bits only for things we want to print,
	which can be more efficient on some file systems.
	Add a new --cache= command-line option that sets the appropriate hint
	flags in the statx call.  These are primarily used with network
	file systems to indicate what level of cache coherency is desired.
	The new option is available unconditionally for better portability,
	and ignored where not implemented.

	New options to set signal handlers for the command being executed.
	--block-signal suggested by Paul Eggert in http://bugs.gnu.org/34488#71
	--default-signal is useful to overcome the POSIX limitation that shell
	must not override inherited signal state, e.g. the second 'trap' here is
	a no-op:

	   trap '' PIPE && sh -c 'trap - PIPE ; seq inf | head -n1'

	Instead use:

	   trap '' PIPE && sh -c 'env --default-signal=PIPE seq inf | head -n1'

	Similarly, the following will prevent CTRL-C from terminating the

	all: detect --help and --version more consistently
	For select programs which accept only --help and --version options
	(in addition to non-option arguments), process these options before
	any other options.

	Before:

	  $ dd bs=1 --help
	  dd: unrecognized option '--help'
	  Try 'dd --help' for more information.

	  $ yes me --help
	  me --help
	  me --help

	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
	directories on systems that can hard-link directories.
	Now, in situations that prohibit hard links to directories,
	'ln A B' merely does 'link("A","B")'.  The new behavior
	avoids some races and should be more efficient.
	This patch was inspired by Bug#10020, which was about 'ln'.
	* bootstrap.conf (gnulib_modules): Add unlinkdir.
	* src/force-link.c (force_linkat, force_symlinkat): New arg for
	error number of previous try.  Return error number, 0, or -1 if
	error, success, or success after removal.  All callers changed.
	* src/ln.c: Include priv-set.h, unlinkdir.h.
	(beware_hard_dir_link): New static var.
	(errnoize, atomic_link): New functions.
	(target_directory_operand): Use errnoize for simplicity.
	(do_link): New arg for error number of previous try.  All callers
	changed.  Do each link atomically if possible.
	(main): Do -r check earlier.  Remove linkdir privileges so we can
	use a single linkat/symlinkat instead of a racy substitute for the
	common case of 'ln A B' and 'ln -s A B'.  Set beware_hard_dir_link
	to disable this optimization.

	cp: 'cp -il A B' no longer fails if user OKs it

	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
	on the i_nocache_eof and o_nocache_eof flags.
	* doc/coreutils.texi (dd invocation): Clarify the alignment
	and persisted caveats on the example applying "nocache"

	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.
	'df -l' triggered systemd to mount the file system because it called
	stat() on the mount point.
	Instead of single-casing "autofs" targets, we can avoid stat()ing
	all dummy file systems (which includes "autofs"), because those are
	skipped later on in get_dev() anyway.

	*src/df.c (filter_mount_list): Also skip dummy file systems unless

	(total_line_count, file_line_count, OCCURS, fix_output_parameters)
	(define_all_fields):
	Use intmax_t, not int, for line counts.
	(DELTA): Remove.  All uses changed.

	(find_occurs_in_text, fix_output_parameters, define_all_fields):
	Omit unnecessary cast.
	(fix_output_parameters): Don’t assume integers fit in 11 digits.
	(fix_output_parameters, define_all_fields):
	Use sprintf return value rather than calling strlen.
	(define_all_fields): Do not rely on sprintf to generate a string
	that may contain more than INT_MAX bytes.
	(main): Use xstrtoimax, not xstrtoul.
	Use xnmalloc to catch integer overflow.

	nohup: simplify by using fcntl
	* src/nohup.c: Do not include cloexec.h.
	(main): Use fcntl rather than dup + set_cloexec_flag.

	sort: use pthread_sigmask, not sigprocmask
	POSIX says sigprocmask has unspecified behavior in a multithreaded
	program like ‘sort’.
	* src/sort.c (pthread_sigmask) [GNULIB_defined_pthread_functions]:
	New macro, for use when ‘sort’ is not multithreaded.
	(cs_enter, cs_leave): Use it.  Pass address, not value, as
	this is typically a tad faster.  All callers changed.

	sort: minor cleanups
	* src/sort.c (move_fd): Rename from move_fd_or_die,
	since it no longer can die.

	sort: file descriptor discipline
	Use O_CLOEXEC when creating file descriptors, so that subsidiary
	processes do not inherit file descriptors that they do not need.
	This is helpful for ‘sort’, as it is a multithreaded program that
	forks and execs.
	* bootstrap.conf (gnulib_modules): Add mkostemp, open, pipe2.
	* src/sort.c (create_temp_file): Open temporary file with O_CLOEXEC.
	(stream_open): Open the stream with O_CLOEXEC.
	(pipe_fork): Create the pipe with O_CLOEXEC.

	O_CLOEXEC is used properly.  This is simpler anyway.
	* tests/misc/sort-files0-from.pl: Adjust to change in diagnostic
	wording.

	kill: fix signal number to name lookup on AIX
	* src/operand2sig.c (operand2sig): AIX uses a different bit pattern
	in the returned status from the wait() functions and from shells.
	Therefore hardcode the selection of the lower bits of the number.
	* NEWS: Mention the fix.

	build: use the appropriate single file include option with xlc
	* configure.ac: Set USE_XLC_INCLUDE when __xlc__ is defined.
	* src/local.mk: Use it to select the appropriate include option.
	Reported by Michael Felt.

	tests: avoid false failures on AIX
	* tests/ln/sf-1.sh: Limit the symlink size to 1MiB
	to avoid memory exhaustion seen on NFS on AIX, giving:
	  + printf '%0*d' 4294967296 0
	  + ./tests/ln/sf-1.sh: line 38: printf: warning: 0: Result too large
	* tests/id/setgid.sh: Skip the test when the adjusted gid

	Reported by Michael Felt.

	sort: handle musl locale differences in --debug reporting
	* src/sort.c (main): Don't assume hard_LC_COLLATE implies

	* tests/misc/sort-debug-warn.sh: Adjust for the now
	separated locale debug info and map the musl specific
	message back to the common case.
	Addresses https://bugs.gnu.org/28054

	seq: produce consistent error messages upon write error
	* src/seq.c (io_error): Use the same error message as would
	be generated at exit time when closing the stdout stream.
	The inconsistency was added with commit v8.25-26-gc92585b.
	This was noticed due to an inconsistency in the expected
	error message generated by seq on musl libc.
	Addresses https://bugs.gnu.org/28054

	tests: fix false failure with large printf formats
	* tests/misc/printf-surprise.sh: With musl libc the
	large printf format does succeed, outputting data.
	To avoid SIGPIPE being generated we ignore that signal
	and then handle the subsequent EPIPE error.
	Addresses https://bugs.gnu.org/28054

	maint: avoid spurious "make distcheck" failure
	When the generated file, doc/constants.texi, happens to be older than
	doc/coreutils.info, it will not be updated until/unless its generated
	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.

	Before this change, one could reproduce the failure by running
	`touch -dyesterday doc/constants.texi && make distcheck`.  It would
	fail with "makeinfo: could not open ../../doc/coreutils.info-t
	for writing: Permission denied"
	* Makefile.am (dist-hook): Touch the two generated files, so that
	they cannot be out of date wrt doc/coreutils.texi.

2017-03-26  Pádraig Brady  <P@draigBrady.com>

	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.

	timeout: fix race possibly terminating wrong process
	The race is unlikely, as timeout(1) needs to receive a signal
	in the few operations between waitpid() returning and exit().
	Also the system needs to have reallocated the just released pid
	in this time window.

	Previously we never disabled the signal handler that sent
	the termination signal to the "child" pid.  However once waitpid()
	has reaped the child, the system is free to allocate that pid,
	so we must ensure we don't process any further signals.

	build: avoid racy failure of "make -jN install"
	Installing with -j2 or greater could result in a failure like
	  /bin/sh: line 29: /P/bin/install: Permission denied
	when /P/bin/install specifies your PATH-selected install program.
	This would arise because we're using "install" to install all
	man/*.1 files, and that command would run concurrently with the one
	that installs "/P/bin/install" itself.  We would run this command:
	"src/ginstall src/ginstall /P/bin/install", and it would result
	in intervals during which the destination file does not exist,
	is empty or incomplete and not executable.  We addressed this
	problem long ago for installation of actual binaries by telling the
	installation rules to use our just-built bin/ginstall (only when not
	cross-compiling) rather than the PATH-resolved "install" program.
	This change is to do the same for those .1 files.
	* src/local.mk (INSTALL): Override automake's default of something
	like "INSTALL = /P/bin/install -c".
	(INSTALL_PROGRAM): Now that we set INSTALL, there is no longer any
	need to set this derived variable.  Its default definition,
	"INSTALL_PROGRAM = ${INSTALL}" does what we require.

	ls: fix %%b format and precompute more
	The old code mishandled --time-spec='+%%b', as it misinterpreted

	The performance part of this patch sped up 'ls' by about 1% on my

	All callers changed.  Reject month abbrs containing '%', as these
	would mess up strftime.  Simplify mbsalign result checking,
	since (size_t) -1 exceeds ABFORMAT_SIZE.

	pinky,who: remove redeclarations of ttyname
	Given that `ttyname` is already conditionally declared in src/system.h,
	other declarations are redundant and problematic for example in ChromeOS
	which has a new FORTIFY implementation that, as an artifact of how it's
	implemented, causes the compiler to complain if certain standard library
	functions are redeclared without special compiler-specific attributes.

	* src/pinky.c: Remove declaration (which was unused anyway).
	* src/who.c: Remove declaration.

	causes stat to also print nanoseconds when printing time stamps

	build: avoid dynamic linking issue on Solaris sparc
	Solaris Studio 12 on sparc (not x86) will not remove
	unused functions, thus leaving a reference to an
	undefined program_name symbol from emit_try_help().

	* src/system.h (emit_try_help): Change from an inline function
	to a macro, so that the inline function is not actually
	defined in libstdbuf.c.

	tests: avoid false failure in tail inotify test
	* tests/tail-2/wait.sh: Restrict inotify specific test portion
	to local file systems and also not with ---disable-inotify specified.
	Failure noticed on NFS.

	tests: avoid false failure due to remove() ignoring u-w on NFS
	* tests/rm/rm1.sh: Also remove the group write bit which
	was required on one NFS setup at least.  Note u-w was
	enough to deny file creation, g-w was also required to
	deny file removal.
	* tests/rm/cycle.sh: Likewise.
	* tests/mv/perm-1.sh: Likewise.

	tests: avoid false failure in preserve-slink-time.sh on GPFS
	* tests/cp/preserve-slink-time.sh: Add a delay between the

	Reported by Assaf Gordon.

	tests: avoid false failure in shred-passes.sh
	* tests/misc/shred-passes.sh: Specify an exact amount to shred,
	to avoid running out of simulated random data on file systems
	with a large st_blksize like GPFS for example.

	tail: disable inotify with only non existent files
	tests/tail-2/F-headers.sh and test/tail-2/retry.sh fail on
	on remote file systems due to tail going into inotify mode
	due to not being able to determine the remoteness of the
	non existent files.

	* src/tail.c (any_non_remote_file): A new function used
	to disable inotify when there are no open files, as
	we can't determine remoteness in that case.
	* NEWS: Mention the bug fix.

	all: don't unconditionally use leaf optimization for NFS
	* gnulib: Update to latest where the only change is to
	not unconditionally enable leaf optimization for fts on NFS,
	as it was seen to abort() with some NFS servers as per:
	https://bugzilla.redhat.com/1299169
	This affects utilities that traverse directories like
	cp, rm, chmod etc.
	* NEWS: Adjust the improvement message to leave only XFS.

	tests: adjust memory limits in head-c.sh
	* tests/misc/head-c.sh: Further increase the limit to 8MB over

	on FreeBSD 9.3 x86_64.

2016-01-18  Pádraig Brady  <P@draigBrady.com>

	tests: adjust delays to avoid false positives
	* tests/rm/dangling-symlink.sh: The effective delay was only
	1.5s.  So delay before the operation, and increase the iteration
	count by 1 to increase the delay to 6.3s.  This failure was
	noticed once on a FreeBSD 10.2 x86_64 virtual machine.
	* tests/dd/stats.sh: Remove quotes on sleep argument
	to ensure arguments are accumulated appropriately.
	* tests/du/move-dir-while-traversing.sh: sleep before operation,
	to increase the effective delay from 1.6s to 3.2s.
	* tests/tail-2/flush-initial.sh: Likewise.
	* tests/tail-2/pipe-f2.sh: Sleep first so that the effective delay
	matches the commented value.

	test: skip test rather than fail with Solaris 10 sed
	* tests/rm/r-root.sh: This test was seen to ERROR due to
	sed input not having a terminating '\n'.  Therefore just skip
	with diagnostics upon failure to adjust the error output with sed.

	tests: avoid false failure with BTRFS subvolumes
	* tests/df/df-symlink.sh: Only check the symmetry of
	the source <-> target lookup, when the source is only mounted once,
	which isn't the case if '.' is a BTRFS subvolume for example.
	Reported by Assaf Gordon on a default OpenSUSE 42.1 install.

	mv: consistently warn about multiply specified source dirs
	* src/copy.c (copy internal): Remember directories irrespective
	of their link count, because on some file systems like BTRFS,
	directories always have a link count of 1.

2016-01-15  Pádraig Brady  <P@draigBrady.com>

	tests: remove a non portable localtime test
	* tests/misc/date.pl: This test was dependent on perl
	unconditionally calling the system localtime() as date(1) does.
	However perl has its own configure checks in place to avoid buggy
	localtime implementations.  Therefore comment out this test
	as a FIXME for now.  This test was seen to fail on FreeBSD 10
	where localtime() returns nonsense values instead of failing
	for arguments >= 2^56.

	tests: adjust memory limits in head-c.sh
	* tests/misc/head-c.sh: Further increase the limit, to account
	for the fact that head(1) needs at least 1.576MB over the base test
	command on FreeBSD 10.  4MB should be enough headroom while
	still providing over allocation protection.
	Reported by Assaf Gordon.

	tests: simplify invalid signal determination for kill -l
	* src/operand2sig.c (operand2sig): Add a detailed comment explaining
	why we validate even very large shell exit status values.
	* tests/misc/kill.sh: Add a test case for the ksh scheme.
	Simplify the INVALID signal number determination which also avoids
	a false failure on systems like FreeBSD 10 with incomplete
	signal list (caused by inaccurate NSIG).

	tests: support older fallocate number formats
	* tests/cp/fiemap-extents.sh: Support RHEL6 fallocate
	which doesn't support IEC suffixes like "MiB" on numbers.
	Also add some extra framework_failure_ protections.
	Reported by Assaf Gordon.

	tests: avoid coredumps when determining memory limits
	* init.cfg (get_min_ulimit_v_): Refactor ulimit call to...
	(ulimit_supported_): ...here, and add calls to avoid coredumps.

	sort: with --debug, flag setlocale() failures on OpenBSD
	Locale categories are not equivalent on OpenBSD,
	and LC_COLLATE only supports "C" for example.
	Now LC_ALL is supported to set multiple other categories
	on OpenBSD, so setlocale(LC_ALL, "") returns a string
	indicating which categories were updated and which ignored.
	Therefore...

	* src/sort.c (main): ...Call setlocale(LC_COLLATE, "")
	to explicitly check whether a specified LC_ALL or
	LC_COLLATE environment variable value is supported
	for the LC_COLLATE category.  Also use !! to explicitly
	convert to bool to support c89 systems where bool is an int,
	and thus would get values > 1.

	commit v8.23-31-g90aa291 failed to consider this case,
	where the previous rename has failed, thus causing the
	following to remove the specified directory:

	  mv dir dir dir

	* src/copy.c (copy_internal): Assume this rename attempt has

	doc: avoid confusing K argument in the man pages of head and tail
	The character 'K' representing numeric user input can be confusing,
	especially in the context where it can be suffixed by the multipliers
	K, M, G, etc.
	Use NUM instead.

	* doc/coreutils.texi (head invocation): Replace @var{k} by @var{num}.
	Also change @var{count} in the paragraph about the obsolete option
	syntax.
	(tail invocation): Likewise.  Furthermore, adjust the option order to
	alphabetical sorting.
	* src/head.c (usage): s/K/NUM/ in as placeholder in the -c and -n
	options.  Furthermore, print the actual DEFAULT_NUMBER instead of the
	hard-coded 10.
	* src/tail.c (usage): s/K/NUM/ in as placeholder in the -c and -n

	maint: fixes to support improved sc_tight_scope
	The gnulib provided sc_tight_scope target was ineffective,
	as it was checking against an invalid blank regular expression,
	and thus ignoring any extern function issues.  This is now
	fixed up in gnulib, and so we need to fix our scoping issues
	before the next gnulib update.

	* cfg.mk: Setup and document the tight_scope config variables
	appropriately.
	* src/selinux.h: Since declared in *_SOURCES, use the two line
	form for the extern function declarations.
	* src/set-fields.h: Add the extern declarations, and since declared
	in noinst_HEADERS use the single line form.

	maint: use adaptive approach for `ulimit -v` based tests
	When configured with either 'symlinks' or 'shebangs' as value for
	the --enable-single-binary option, tests based on `ulimit -v` are
	skipped.  The reason is that the multicall 'coreutils' binary requires
	much more memory due to shared libraries being loaded, and the size of
	the 'date' binary (~290KiB) compared to the multicall binary (~5MiB),
	of course.  Finally, in the case of 'shebangs', the starting shell
	requires more memory, too

	Instead of using hard-coded values for the memory limit, use an
	adaptive approach: first determine the amount of memory for a similar,
	yet more trivial invocation of the command, and then do the real test
	run using that limit (plus some buffer in some cases).

	* init.cfg (require_ulimit_v_): Remove function.
	(get_min_ulimit_v_): Add function to determine the minimum memory limit
	required for a given command in an adaptive way.
	* cfg.mk (sc_prohibit_test_ulimit_without_require_): Change the name
	of the above function in the syntax-check rule.
	* tests/cp/link-heap.sh: Use the above function to determine the

	Instead we remove the problematic -f option to sort
	which actually doesn't change the order given
	our current input.

	maint: avoid false syntax-check failure in distcheck

2015-07-03  Pádraig Brady  <P@draigBrady.com>

	tests: avoid side effects of $SHELL environment variable
	Since non interactive shells don't generally set $SHELL,
	its value is propagated through the tests and may cause issues;
	for example if $SHELL implicitly adjusts $PATH when run.
	Instead we set $SHELL to that determined by the posix-shell module,
	and use that consistently for all test sub scripts,
	including those created thorugh the `split --filter` command.

	* tests/local.mk: Explicitly set $SHELL to $(PREFERABLY_POSIX_SHELL)
	which defaults to $CONFIG_SHELL and thus usually /bin/sh.
	* tests/envvar-check: Remove bash environment variables with
	side effects, in case /bin/bash was selected for $SHELL.
	* tests/misc/help-version.sh: Remove redundant initialization of $SHELL.

	wc: fix reading of /proc files on aarch64
	tests/misc/wc-proc.sh fails when the page size is 64K

	* src/wc.c (wc): The lseek adjustment should be based on st_blksize,
	rather than on the internal buffer size.  This is significant on
	aarch64 where st_blksize in /proc is the 64K (the page size) and
	thus larger than the internal buffer.
	* src/split.c (main): Even though the similar processing is done
	on the internal buffer size, that's based on st_blksize and
	so fine in this regard.  Add an assert to enforce this.
	Avoid this path for the undocumented ---io-blksize option.

	factor: ensure atomic output through pipes
	The new tests/misc/factor-parallel.sh test was
	seen to fail on FreeBSD (derived) systems, which was
	due to split(1) --filter reading partial lines
	through pipes, as factor(1) was writing a little
	over PIPE_BUF each time.

	* src/factor.c (lbuf): A new structure to internally buffer lines.
	(lbuf_alloc): A new function to allocate enough at program start.
	(lbuf_putint): A new function to buffer a uintmax_t.
	(lbuf_flush): A new function to write directly to standard output.
	(lbuf_putc): A new function to buffer a character and if enough
	lines are buffered, then output complete lines <= PIPE_BUF,
	and continue to buffer the rest.
	(main): Call the internal buffer allocator, and register
	the final flush from the internal buffer at program exit.

	I.E. on older setups with static /etc/mtab, df will now

	The LD_PRELOAD checks by -fsanitize=address are overly strict:
	https://groups.google.com/forum/#!topic/address-sanitizer/jEvOJgkDqQk
	A workaround is to first export LD_PRELOAD=libasan.so.2

	GCC 5.1.1 -fsanitize=undefined with glibc 2.21 is returning:
	"runtime error: null pointer passed as argument 1,
	 which is declared to never be null"
	* src/ptx.c (sort_found_occurs): Avoid the call with no entries.

	factor: avoid interspersed lines for parallel runs
	* src/factor.c (n_out): A new global variable to track
	how much data has been written to stdout.
	(print_factors_single): Use n_out to determine whether
	to flush the current (and previous) lines.
	* tests/misc/factor-parallel.sh: Add a new test.
	* tests/local.mk: Reference the new test.
	* NEWS: Mention the bug fix.

	seq: handle exponents more consistently
	src/seq.c (scan_arg): Set precision and width _after_ exponentiation.
	For example, this will make '1.1e1 12' and '11 1.2e1' equivalent.
	One can still set the precision by specifying extra precision on
	the start value, or more naturally with a precision on a step value.
	* tests/misc/seq-precision.sh: Add new cases.

	seq: use consistent output format with hex integers
	* src/seq.c (scan_arg): Set precision to 0 for hex constants
	(while avoiding hex floats).  This will use then use the
	fast path for these arguments.  Note we also set the precision
	of inf to 0 here, which ensures we use consistent precision
	on output where possible.
	* tests/misc/seq-precision.sh: Add corresponding test cases.

	seq: support inf last item more generally/efficiently
	* src/seq.c (main): Call seq_fast for infinite last value.
	This implicitly avoids format conversion on the
	999999 -> 1000000 transition.
	* src/seq.c (seq_fast): Generalize the buffer handling,
	and adjust to handle the "inf" last value specifics.
	* tests/misc/seq-precision.sh: A new test.
	* tests/local.mk: Reference the new test.

	* tests/misc/numfmt.pl: Restrict limit tests to supported platforms.

	numfmt: handle leading zeros correctly
	* src/numfmt.c (simple_strtod_int): Don't count leading zeros
	as significant digits.  Also have leading zeros as optional
	for floating point numbers.
	* tests/misc/numfmt.pl: Add test cases.
	* NEWS: Mention the fix.

2015-06-22  Pádraig Brady  <P@draigBrady.com>

	numfmt: avoid integer overflow when rounding
	Due to existing limits this is usually triggered
	with an increased precision.  We also add further
	restrictions to the output of increased precision numbers.

	* src/numfmt.c (simple_round): Avoid intmax_t overflow.
	(simple_strtod_int): Count digits consistently
	for precision loss and overflow detection.
	(prepare_padded_number): Include the precision
	when excluding numbers to output, since the precision
	determines the ultimate values used in the rounding scheme
	in double_to_human().
	* tests/misc/numfmt.pl: Add previously failing test cases.
	* NEWS: Mention the fix.

2015-06-21  Pádraig Brady  <P@draigBrady.com>

	numfmt: support user specified output precision

	* NEWS: Likewise.

2015-06-19  Dylan Cali  <calid1984@gmail.com>

	numfmt: implement support for field ranges
	* src/numfmt.c: Replace field handling code with logic that understands
	field range specifiers.  Instead of processing a single field and
	printing line prefix/suffix around it, process each field in the line
	checking whether it has been included for conversion.  If so convert and
	print, otherwise just print the unaltered field.
	(extract_fields): Removed.
	(skip_fields): Removed.
	(process_line): Gutted and heavily reworked.
	(process_suffixed_number): FIELD is now passed as an arg instead of
	using a global.
	(parse_field_arg): New function that parses field range specifiers.
	(next_field): New function that returns pointers to the next field in
	a line.
	(process_field): New function that wraps the field conversion logic
	(include_field): New function that checks whether a field should be
	converted
	(compare_field): New function used for field value comparisons in a
	gl_list.
	(free_field): New function used for freeing field values in a gl_list.
	Global variable FIELD removed.
	New global variable all_fields indicates whether all fields should be
	processed.
	New global variable all_fields_after stores the first field of a N-
	style range.
	New global variable all_fields_before stores the last field of a -M
	style range.
	New global variable field_list stores explicitly specified fields to
	process (N N,M or N-M style specifiers).
	(usage): Document newly supported field range specifiers.
	* bootstrap.conf: Include xlist and linked-list modules.  numfmt now
	uses the gl_linked_list implementation to store the field ranges.
	* tests/misc/numfmt.pl: Add tests for 'cut style' field ranges.
	Adjust existing tests as partial output can occur before an error
	Remove test for the 'invalid' field -5.. this is now a valid range.
	* gnulib: update to avoid compiler warnings in linked-list.
	* NEWS: Mention the new feature.

2015-06-19  Pádraig Brady  <P@draigBrady.com>

	doc: use correct units in df | numfmt example
	* src/numfmt.c (usage): Don't scale output from df
	so that numfmt outputs the correct values.

	numfmt: handle suffixes consistently with --{from,to}-unit
	* src/numfmt.c (unit_to_umax): Support SI (power of 10) suffixes
	with the --from-unit and --to-unit options.  Treat suffixes like
	is done with --from=auto, which for example will change the meaning
	of --to-unit=G to that of --to-unit=Gi.  The suffix support was
	previously undocumented and it's better to avoid the traditional
	coreutils suffix handling in numfmt by default.
	* doc/coreutils.texi: Document the new behavior.  Also fix a typo
	mentioning {from,to}=units=.
	* tests/misc/numfmt.pl: Adjust accordingly.
	* NEWS: Mention the change in behavior.

	* tests/tail-2/F-vs-rename.sh: Likewise.

	tail: display file headers correctly with inotify
	* src/tail.c (tail_forever_inotify): Use the fspec pointer to
	distinguish previously output files, rather than a descriptor
	from the inotify event.  That event descriptor was that of
	the parent directory when files were created or renamed etc.
	(check_fspec): Adjust for the new comparison.  Also show the
	header when the file is truncated, since we show data
	in this case also.
	* tests/tail-2/F-headers.sh: A new test case.

	build: port to AIX
	Problems reported by Michael Felt, and and part of this fix taken

	http://bugs.gnu.org/20733#112
	* configure.ac (stdbuf_supported): Check for warnings, and
	for -fPIC and -shared, for AIX.
	* src/stat.c (STRUCT_STATVFS): Define to struct statvfs64 if
	STATFS is statvfs64.
	* src/sync.c (sync_arg) [_AIX]: Open in write mode,

2015-06-03  Pádraig Brady  <P@draigBrady.com>

	build: add a dependency on the gnulib tempname module
	* bootstrap.conf: Add "tempname" which is needed by mktemp(1).
	The explicit dependency supports running gnulib-tool with
	the --conditional-dependencies option, used to minimize built
	modules.  Note on a Fedora 22 system, that results in avoiding
	redundant builds of: areadlinkat.o asnprintf.o fd-hook.o
	fseterr.o printf-args.o printf-parse.o sockets.o vasnprintf.o.
	However --conditional-dependencies is not enabled, since it
	currently precludes the inclusion of gnulib tests.

2015-06-02  Pádraig Brady  <P@draigBrady.com>

	Mainly with build fixes for Mac OS X.

2015-06-01  Pádraig Brady  <P@draigBrady.com>

	tests: fix race in tail test without inotify
	* tests/tail-2/wait.sh: Without inotify, skip a portion of the test
	that checks that -F never outputs from a tailed descriptor
	after the followed name is recreated, because tail_forever()
	doesn't guarantee that.
	Noticed at http://hydra.nixos.org/build/22766288

	tests: fix false failure on loaded systems
	* tests/misc/uniq-perf.sh: Use our standard 10s timeout,
	which is sufficient to trigger the failure and also
	avoids a false failure on slow/loaded systems.
	Noticed at http://hydra.nixos.org/build/22766288

2015-05-30  Pádraig Brady  <P@draigBrady.com>

	maint: avoid new coverity warnings
	* src/sync.c (sync_arg): Initialise variable to avoid

	* src/head.c (elide_tail_bytes_file): Support this function
	with ---presume-input-pipe and larger files,
	which regressed with commit v8.23-47-g2662702.
	(elide_tail_lines_file): Likewise.
	* src/dd.c (dd_copy): Explicitly don't try to ftruncate()
	upon failure to lseek() (the existing check against
	st_size was already protecting that).
	* src/factor.c (factor_using_squfof): Assert (only when
	linting due to performance) to avoid the implication of
	divide by zero.
	* src/od.c (read_block): Remove dead code.
	* src/tac.c (tac_seekable): Likewise.
	* src/ls.c (gobble_file): Likewise.

2015-05-28  Pádraig Brady  <P@draigBrady.com>

	build: remove workarounds for unsupported gettext versions
	Now that we depend on gettext >= 0.19.2 remove the workaround
	for issues in autopoint 0.18.3.  Note the scheme currently used in
	newer gettext (autopoint) to avoid these issues requires
	autoconf >= 2.69, therefore we update this requirement also.

	Note the gettext version dependence from gnulib comes from
	gnulib using gettext macros, and coreutils indirectly depends on
	the gettext module due to:
	http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=commitdiff;h=41dca647
	bootstrap will then update m4/po.m4 and thus require a
	supportng gettext version.

	tail: fix inotify startup races
	The previous fixes to races in the various tail tests,
	identified actual races in the tail inotify implementation.
	With --follow=descriptor, if the tailed file was replaced before
	the inotify watch was added, then any subsequent changes were ignored.
	Similarly in --follow=name mode, all changes to a new name were
	effectively ignored if that name was created after the original open()
	but before the inotify_add_watch().

	* src/tail.c (tail_forever_inotify): Fix 3 cases.
	1. With -f, don't stop tailing when file removed before watch.
	2. With -f, watch right file when file replaced before watch.
	3. With -F, inspect correct file when replaced before watch.
	Existing tests identify these when tail compiled with TAIL_TEST_SLEEP.
	* tests/tail-2/inotify-rotate-resources.sh:
	This test also identifies the issue with --follow=name
	when TAIL_TEST_SLEEP is used.  Adjust so the test is immune
	to such races, and also fail quicker on remote file systems.
	* tests/tail-2/inotify-race2.sh: A new test using GDB,
	based on inotify-race.sh, which tests the -F race
	without needed recompilation with sleeps.

	tests: avoid hung processes due to gdb SIGCONT handling
	* tests/tail-2/inotify-race.sh: Add a `wait` to ensure that
	we reap all background gdb and tail processes.  That resulted
	in the test hanging intermittently and upon investigation was
	due to gdb intermittently failing to terminate the child process
	due to receiving a SIGCONT signal.  Therefore we avoid using
	timeout(1) which sends that signal, and instead rely on tail's
	inbuilt --pid monitoring on a background sleep process.
	Given this new implementation, the VERY_EXPENSIVE guard was removed.
	Related issues with this test hanging were previously discussed at:
	https://lists.gnu.org/archive/html/bug-coreutils/2009-12/msg00025.html

	tests: fix races in and standardize the tail tests
	* tests/tail-2/F-vs-missing.sh: Use standard "fastpoll" options
	(-s.1 --max-unchanged-stats=1) to speedup the non-inotify case.
	Add the non-inotify case to the test. `wait` on the background
	tail process to terminate which should avoid the need for the
	non standard `retry_delay_ cleanup ...` on NFS.
	* tests/tail-2/F-vs-rename.sh: Remove 'out' at the start of the loop,
	to avoid a race in checking its contents.  Also ensure 'a' & 'b'
	files are present before the tail process starts.  Use the standard
	"fastpoll" options as above.
	* tests/tail-2/f-vs-rename.sh: Likewise.
	* tests/tail-2/append-only.sh: Use more standard variable names.
	* tests/tail-2/flush-initial.sh: Use "fastpoll" options for
	non-inotify platforms.  Also `wait` on the background tail to avoid
	stray processes and file cleanup issues on NFS.
	* tests/tail-2/inotify-hash-abuse.sh: Always run non-inotify case.
	Use "fastpoll" options.  Use a more standard retry_delay_ instead
	of a hardcoded sleep loop.  Add a `wait` on the background tail.
	* tests/tail-2/inotify-hash-abuse2.sh: Likewise.
	* tests/tail-2/inotify-rotate-resources.sh: Wait just on the
	specific tail $pid needed.
	* tests/tail-2/inotify-rotate.sh: Use "fastpoll" options.
	* tests/tail-2/pid.sh: Use standard variable names.
	Add a `wait` on the background tails.
	* tests/tail-2/pipe-f2.sh: Likewise.

	* tests/tail-2/wait.sh: Likewise.  Speedup by using sub second
	parameters to timeout(1).  Improve the part ensuring that
	-F never follows a renamed file.
	* tests/tail-2/infloop-1.sh: Remove invalid test.  tail(1) was not
	being passed the --pid=$yes_pid option, retry_delay_ wasn't used
	to avoid races, and yes could write huge files before being killed.
	* tests/local.mk: Remove the invalid test reference.
	* tests/tail-2/assert-2.sh: Rewrite using retry_delay_().  Since
	no longer hardcoding large delays, remove the VERY_EXPENSIVE tag.

	maint: really fix wildcard quoting in sc_tests_executable
	* cfg.mk (sc_tests_executable): The previous commit avoided
	the globbing, but also passed on the quoted wildcards to find(1).
	We could use eval to handle the quoting, though that's a bit
	awkward and dangerous, so instead explicitly disable globbing
	for the whole make target subshell.  Note noglob is not available
	on solaris, where we fall back to set -f.  Note also that zsh
	uses set -F for this, but that's moot here.  Also correct the
	find(1) expression to include the -o between each wildcard.

	maint: fix wildcard quoting in sc_tests_executable
	* cfg.mk (sc_tests_executable): If there are files with
	$TEST_EXTENSIONS in the current directory, then the
	lack of quoting of the $test_extensions_rx contents
	could result in globbing and an inconsequential run.
	find(1) produces warnings only with more than one expansion.

	wc: speedup counting of short lines
	Using a test file generated with:
	  yes | head -n100M > 2x100M.txt

	before> time wc -l 2x100M.txt
	  real 0.842s
	  user 0.810s

	after> time wc -l 2x100M.txt
	  real 0.142s
	  user 0.111s
	  sys  0.031s

	* src/wc.c (wc): Split the loop that deals with -l into 3.
	The first is used at the start of the input to determine if
	the average line length is < 15, and if so the second loop is
	used to look for '\n' internally to wc.  For longer lines,
	memchr is used as before to take advantage of system specific
	optimizations which any outweigh function call overhead.
	Note the first 2 loops could be combined, though in testing,
	GCC 4.9.2 at least, wasn't sophisticated enough to separate
	the loops based on the "check_len" invariant.
	Note also __builtin_memchr() isn't significant here as
	GCC currently only applies constant folding with that.
	* NEWS: Mention the improvement.

	* tests/misc/yes.sh: Add a test case for the many small arguments case.

2015-03-10  Pádraig Brady  <P@draigBrady.com>

	yes: output data more efficiently
	yes(1) may be used to generate repeating patterns of text
	for test inputs etc., so adjust to be more efficient.

	Profiling the case where yes(1) is outputting small items
	through stdio (which was the default case), shows the overhead
	of continuously processing small items in main() and in stdio:

	    $ yes >/dev/null & perf top -p $!
	    31.02%  yes           [.] main
	    27.36%  libc-2.20.so  [.] _IO_file_xsputn@@GLIBC_2.2.5
	    14.51%  libc-2.20.so  [.] fputs_unlocked

	     1.98%  yes           [.] fputs_unlocked@plta

	Sending more data per stdio call improves the situation,
	but still, there is significant stdio overhead due to memory copies,
	and the repeated string length checking:

	    $ yes "`echo {1..1000}`" >/dev/null & perf top -p $!
	    42.26%  libc-2.20.so  [.] __GI___mempcpy
	    17.38%  libc-2.20.so  [.] strlen
	     5.21%  [kernel]      [k] __srcu_read_lock

	     1.44%  yes           [.] main

	We can avoid all stdio overhead by building up the buffer
	_once_ and outputting that, and the profile below shows
	the bottleneck moved to the kernel:

	     0.36%  yes           [.] write@plt

	Note this change also ensures that yes(1) will only write
	complete lines for lines shorter than BUFSIZ.

2015-02-24  Pádraig Brady  <P@draigBrady.com>

	tee: add --write-error to control handling of closed pipes
	tee is very often used with pipes and this gives better control
	when writing to them.  There are 3 classes of file descriptors
	that tee can write to: files(1), pipes(2), and early close pipes(3).
	Handling write errors to 1 & 2 is supported at present with the caveat
	that failure writing to any pipe will terminate tee immediately.
	Handling write errors to type 3 is not currently supported.
	To improve the supported combinations we add these options:

	 --write-error=warn
	   Warn if error writing any output including pipes.
	   Allows continued writing to still open files/pipes.
	   Exit status is failure if any output had error.
	 --write-error=warn-nopipe, -p
	   Warn if error writing any output except pipes.
	   Allows continued writing to still open files/pipes.
	   Exit status is failure if any non pipe output had error.
	 --write-error=exit
	   Exit if error writing any output including pipes.
	 --write-error=exit-nopipe
	   Exit if error writing any output except pipes.

	Use the "nopipe" variants when files are of types 1 and 3, otherwise
	use the standard variants with types 1 and 2.  A caveat with the above
	scheme is that a combination of pipe types (2 & 3) is not supported
	robustly.  I.e. if you use the "nopipe" variants when using both type
	2 and 3 pipes, then any "real" errors on type 2 pipes will not be
	diagnosed.
	  Note also a general issue with type 3 pipes that are not on tee's
	stdout, is that shell constructs don't allow to distinguish early
	close from real failures.  For example `tee >(head -n1) | grep -m1 ..`
	can't distinguish between an error or an early close in "head" pipe,
	while the fail on the grep part of the pipe is distinguished
	independently from the resulting pipe errors.  This is a general
	issue with the >() construct, rather than with tee itself.

	* NEWS: Mention the new feature.
	* doc/coreutils.texi (tee invocation): Describe the new option.
	* src/tee.c (usage): Likewise.

	tests: avoid a FP on aarch64 when comparing env/printenv output
	The following test fails on aarch64 on openSUSE's OpenBuildService

	build: use the system printf routines in most cases
	glibc <= 2.5 would crash when passed invalid long double values,
	therefore internal gnulib routines were used, essentially only by od,
	to output such invalid values.  Later glibc versions don't crash,
	as per https://sourceware.org/bugzilla/show_bug.cgi?id=4586
	and subsequently od was adjusted to use the system printf routines
	through the use of the ftoastr module with commit v8.7-22-ga71c22f.
	Consequently our testing of this feature was moot, and use of
	the gnulib printf replacement for printf(1), od(1) and error(3) etc.
	was redundant.

	* configure.ac (gl_printf_safe): Unset so that we don't check that
	"nan" is output for these long double values.
	* tests/misc/od-float.sh: Adjust all existing checks to fail if od
	exits with failure status (like crashing for example).  Add a new case
	for one of the problematic invalid long double values for x86_64.
	We only check that od exits successfully at present, which may change
	if https://sourceware.org/bugzilla/show_bug.cgi?id=17661 is resolved.

	maint: avoid signed overflow warning with -O3
	Prompted by the implicit -O3 added by american-fuzzy-lop,
	seen with GCC 4.9.2 on x86_64.

	  src/pr.c: In function 'print_files.part.5':
	  src/pr.c:1781:6: error: assuming signed overflow does not occur
	  when simplifying conditional to constant [-Werror=strict-overflow]
	     if (cols_ready_to_print () == 0)

	This happens because cols_ready_to_print() is inlined
	thus reducing the comparison to the N variable in print_page().
	Now this can't overflow due to the protection when parsing the
	specified column, but use an unsigned type to avoid the
	apparent signed overflow.

	* src/pr.c (cols_ready_to_print): Increment an unsigned type to
	avoid the subsequent signed overflow warning.

	du: handle sub-bind-mount cycles gracefully
	This patch fixes the handling of sub-bind-mount cycles which are
	incorrectly detected as the file system errors.  If you bind mount the
	directory 'a' to its subdirectory 'a/b/c' and then run 'du a/b' you
	will get the circular dependency warning even though nothing is wrong
	with the file system.  This happens because the first directory that is
	traversed twice in this case is not a bind mount but a child of bind
	mount.  The solution is to traverse all the directories in the cycle
	that fts detected and check whether they are not a (bind) mount.

	* src/du.c (mount_point_in_fts_cycle): New function that checks whether
	any of the directories in the cycle that fts detected is a mount point.
	* src/du.c (process_file): Update the function to use the new function
	that looks up all the directories in the fts cycle instead of only the
	last one.
	* tests/du/bind-mount-dir-cycle-v2.sh: New test case that exhibits the
	described behavior.
	* tests/local.mk: Reference the new root test.
	* NEWS: Mention the bug fix.

	mv: fail when moving a file to a hardlink
	We may run into a race condition if we treat hard links to the same file
	as distinct files.  If we do 'mv a b' and 'mv b a' in parallel, both a
	and b can disappear from the file system.  The reason is that in this
	case the unlink on src is called and the system calls can end up being

	maint: avoid new signed overflow warning on 32 bit
	Prompted by http://hydra.nixos.org/build/15682577
	with GCC 4.8.3 on i686

	  src/tac.c:557:6: error: assuming signed overflow does not occur
	  when simplifying conditional to constant [-Werror=strict-overflow]
	     if (bytes_copied < 0)

	This happens because copy_to_temp() is inlined in tac_nonseekable(),
	thus reducing the comparison to the bytes_copied variable in
	copy_to_temp.  Now this can't overflow on either 32 or 64 bit
	due to the protection of the preceding fwrite().  We could use a
	guard like "if (bytes_copied <= OFF_T_MAX - bytes_read)" to avoid
	the warning, but rather than a runtime branch, just use an unsigned
	type to avoid apparent signed overflow on systems where the accumulation
	is not promoted to unsigned (32 bit size_t, 64 bit off_t).

	tests: fix false du failure on newer XFS
	On XFS, when creating the ~2G test file 'big' in a for-loop by
	appending 20M each time, the file ends up using ~4G - visible in
	'st_blocks'.  The unused space would be reclaimed later.
	This feature is called "speculative preallocation" which aims at
	avoiding fragmentation.
	According to the XFS FAQ [1], there are two particular aspects of
	XFS speculative preallocation that are triggering this:

	  1. "Applications that repeatedly trigger preallocation and reclaim
	     cycles [after file close] can cause fragmentation.
	     Therefore, this pattern is detected and causes the preallocation
	     to persist beyond the lifecycle of the file descriptor."

	  2. "Preallocation sizes grow as files grow larger."

	[1] http://xfs.org/index.php/XFS_FAQ

	Avoid one of the above by only doing a single close (reclaim cycle).

	* tests/du/2g.sh: Similar to the fix for a dd test (see commit
	v8.22-65-g7c03fe2), avoid speculative preallocation by creating
	the 'big' file in one go instead of appending to it in the loop.
	Remove debugging statements as the output with 'set -x' is
	sufficient nowadays.

	doc: clarify that duplicate NFS mounts are skipped by df
	* doc/coreutils.texi (df invocation): Add a sentence that eliding

2014-08-19  Pádraig Brady  <P@draigBrady.com>

	df: improve mount point selection with inaccurate mount list
	v8.23 has a test failure on Fedora rawhide build servers
	in tests/df/skip-duplicate.sh.  This was due to no '/'
	entry being output by df.  That was due to an inaccurate
	/proc/mounts on the build environment as stat(/mnt/point)
	identified all these /proc/mounts entries as having the
	same device id:

	  /                    rootfs
	  /                    /dev/md1
	  /dev                 devtmpfs
	  /run                 tmpfs
	  /boot                /dev/md0
	  /proc/filesystems    /dev/md1

	Since the device name on the right changes for a given id,
	that causes the entries to be continually replaced, thus
	resulting in no '/' entry.  I'm guessing this is due to
	the mock environment bind mounting unneeded or sensitive
	items to a dummy file on the host / (/dev/md1) though
	have not looked into those details.

	So rather than relying on an accurate /proc/mounts,
	the attached patch takes a more conservative replacement
	approach and only swaps a new device entry when the
	mount point matches.  That should handle all practical
	cases while also avoiding this situation.

	* src/df.c (filter_mount_list): Only replace entries with
	different device names when the mount point also matches.

	chroot: perform chdir("/") again unless new --skip-chdir is specified
	Since commit v8.22-94-g99960ee, chroot(1) skips the chroot(2) syscall
	for "/" arguments (and synonyms).  The problem is that it also skips
	the following chdir("/") call in that case.  The latter breaks existing
	scripts which expect "/" to be the working directory inside the chroot.
	While the first part of the change - i.e., skipping chroot("/") - is
	okay for consistency with systems where it might succeed for a non-root
	user, the second part might be malicious, e.g.

	  cd /home/user && chroot '/' bin/foo

	In the "best" case, chroot(1) could not execute 'bin/foo' with ENOENT,
	but in the worst case, chroot(1) would execute '/home/user/bin/foo' in
	the case that exists - instead of '/bin/foo'.

	Revert that second part of the patch, i.e., perform the chdir("/)
	in the common case again - unless the new --skip-chdir option is
	specified.  Restrict this new option to the case of "/" arguments.

	* src/chroot.c (SKIP_CHDIR): Add enum.
	(long_opts): Add entry for the new --skip-chdir option.
	(usage): Add --skip-chdir option, and while at it, move the other

	run in any case - unless --skip-chdir is specified.
	Add a 'newroot' variable for the new root directory as it is used
	in a couple of places now.
	* tests/misc/chroot-fail.sh: Invert the last tests which check the
	working directory of the execvp()ed program when a "/"-like
	argument was passed: now expect it to be "/" - unless --skip-chdir
	is given.
