	version 8.25
	* NEWS: Record release date.

2016-01-19  Pádraig Brady  <P@draigBrady.com>

	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
	ln and the cp so that there is enough difference between
	the timestamps so GPFS won't discard the update.
	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.
	Reported by Assaf Gordon.

2016-01-19  Pádraig Brady  <P@draigBrady.com>

	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.

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

	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.

2016-01-18  Assaf Gordon  <assafgordon@gmail.com>

	tests: adjust memory limits in head-c.sh
	* tests/misc/head-c.sh: Further increase the limit to 8MB over
	the base test command.  5.1MB was seen as minimum extra needed
	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.
	Reported by Assaf Gordon.

2016-01-16  Pádraig Brady  <P@draigBrady.com>

	tests: fix false failure with spaces in absolute $PWD
	* tests/install/create-leading.sh: Ensure $PWD is quoted.
	Reported by `make dist-check`.

2016-01-16  Pádraig Brady  <P@draigBrady.com>

	build: update gnulib submodule to latest
	Mainly for:

	* dce117a sig2str: list all signals on FreeBSD >= 7
	* cff4b38 acl-permissions: port to USE_ACL==0 platforms

2016-01-16  Pádraig Brady  <P@draigBrady.com>

	tests: show mount list on failure for df tests
	* init.cfg (dump_mount_list_): A new function to output the
	system mount list.
	* tests/df/df-symlink.sh: Call dump_mount_list_ upon failure.
	* tests/df/over-mount-device.sh: Likewise.
	* tests/df/problematic-chars.sh: Likewise.
	* tests/df/skip-rootfs.sh: Likewise.
	* tests/df/total-verify.sh: Likewise.
	* tests/df/unreadable.sh: Likewise.

	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.

2016-01-14  Pádraig Brady  <P@draigBrady.com>

	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.
	Reported by Assaf Gordon.

2016-01-13  Pádraig Brady  <P@draigBrady.com>

	maint: remove temporary doc/constants.texi-t during build
	* doc/local.mk (constants.texi): Remove temp file.

	maint: fix old spelling mistakes in NEWS
	* NEWS: s/descendent/descendant/; s/indiscriminite/indiscriminate/.
	* cfg.mk (old_NEWS_hash): Update via `make update-NEWS-hash`.

	doc: suggest dd "sync" flag to maximize "nocache" effectiveness
	doc/coreutils.texi (dd invocation): Add oflag=sync to the streaming
	example.  Also reference the "direct" flag.  Mention this is only
	a request to the system.
	* src/dd.c (usage): Mention the "sync" flag along with "nocache".
	Also mention that it's only a request to drop the cache.
	* THANKS.in: Add reporter Francois Rigault.

	doc: mention the '0#' printf flags with stat %a
	* src/stat.c (usage): Mention the '#' and '0' flags are useful with %a.
	* doc/coreutils.texi (stat invocation): Likewise.  Also give an example
	printing unambiguous octal output.
	Reported at http://bugs.debian.org/810539

2016-01-13  Pádraig Brady  <P@draigBrady.com>

	mv: fix data loss with repeated source dir and same destination
	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
	succeeded, as a previous failure will already have been handled,
	and we don't want to remove the source directory in this case.
	* tests/cp/duplicate-sources.sh: Consolidate this test file to...
	* tests/mv/dup-source.sh: ...here.  Add test cases for same
	source and dest.
	* tests/local.mk: Remove the consolidated test.
	* NEWS: Mention the bug fix.

	Reported at https://bugzilla.redhat.com/1297464

2016-01-13  Pádraig Brady  <P@draigBrady.com>

	tests: include part of wc-files0.sh skipped by mistake
	* tests/misc/wc-files0.sh: $fail is always set to 0,
	so correct the test to include that part of the test case.

	wc: avoid ambiguous output with '\n' in file names
	* src/wc.c (write_counts): Shell escape the file name
	if it contains '\n' so only a single line per file is output.
	* tests/misc/wc-files0.sh: Add a test case.
	* NEWS: Mention the improvement.

	tests: fix races wrt output files of background processes
	At least the false positive in tail-2/follow-stdin.sh could be seen
	on a 4-core i5 system with -j8.  Fix similar cases. too.

	* tests/tail-2/follow-stdin.sh: Empty the 'out' file in each iteration.
	Otherwise, under heavy system load, 'check_tail_output' would see the
	expected output from the previous round before tail would have the
	chance to come up in the background.
	While at it, move the creation of the 'exp' file out of the loop.
	* tests/dd/stats.sh: Empty the output file of the background process
	here, too.

	(usage): Document for "local" and "combination" settings.
	* doc/coreutils.texi (local stty settings): Document,
	mentioning that this option is supported but ignored on GNU/Linux.

2016-01-06  Pádraig Brady  <P@draigBrady.com>

	stty: support [-]drain setting to control waiting for pending Tx
	Instead of commit v8.24-132-g5171bef which only provides
	control to disable this behavior (with -I), provide
	the symmetrical "[-]drain" special setting.

	* src/stty.c (main): Parse the [-]drain setting instead of -I,
	and treat like a global option.
	(usage): Adjust accordingly.
	* tests/misc/stty.sh: Test "drain" with and without options.
	* NEWS: Mention the new feature.

2016-01-04  Pádraig Brady  <P@draigBrady.com>

	stty: support -I, --immediate to not wait for pending transmission

	doc: avoid unwanted display of the 'coreutils' command info
	* doc/coreutils.texi (coreutils): Remove this direntry
	so that `info coreutils` will display the table of contents,
	rather than the unlikely intended coreutils Multi-call invocation.
	This also supports lookups like `info coreutils readlink`,
	but note that only works with the standard info viewer,
	and not with pinfo for example.

	doc: mention in more places that -D will create --target-directory
	* src/install.c (usage): Mention this commonly required functionality
	in the -D option description.
	* doc/coreutils.texi (install invocation): Likewise for the
	--target-directory description.

	install: only attempt to create a target dir once
	* src/install.c (main): As an optimization, when calling
	install_file_in_dir() for each file, only attempt to create
	the target directory once, as this is invariant over the loop.

	install: fix relative copies to absolute directory with -D
	* src/install.c (mkancesdirs_safe_wd): Unconditionally
	restore the current working directory when possibly called
	multiple times (from install_file_in_dir()).

	Since commit v8.23-60-g414a8cf, the above check failed to find sources
	where the length of the longest line is a 3 or more digit number.

	* cfg.mk (sc_long_lines): Remove the '\' escape character before '{'
	and '}', because this would mean literal '{' and '}' characters in
	an extended regular expression in sed(1).

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

	maint: avoid a sc_long_lines failure in recent commit

	Also, make the output a bit more precise while we're at it.
	* NEWS: Document this.
	* src/dd.c (previous_time): Remove, replacing with ...
	(next_time): New var.  All uses changed.
	This avoids some rounding errors, and should be a bit faster.
	(newline_pending): Remove, replacing with ...
	(progress_len): New var.  All uses changed.
	This lets us keep track of how many trailing spaces to append.
	(print_xfer_stats): Get the time first thing, so that it's
	closer to being correct.  Count the bytes output, and append
	trailing spaces if needed.  Add remarks to translators about
	translation lengths.

	dd: summarize in --human-readable format too
	Problem reported by Linda Walsh in: http://bugs.gnu.org/17505
	* NEWS: Document this.
	* doc/coreutils.texi (dd invocation): Use a simpler script.
	Adjust output example to match new behavior.
	* src/dd.c (human_size): Remove.
	All uses changed to use human_readable and ...
	(human_opts): ... this new constant.
	(abbreviation_lacks_prefix): New function.
	(print_xfer_stats): Use it.  Output both --si and --human-readable
	summaries, but only if they have prefixes.
	* tests/dd/reblock.sh, tests/dd/stats.sh: Test new behavior.

	build: rely on umask for setting permissions in tarball
	Commit v8.24-116-g896006b changed the file permissions for the tarball
	using ug+rw.  Better to let the umask decide whether the file should
	be group-writeable or not.

	* Makefile.am (dist-hook): Change chmod call from 'ug+rw' to '+rw'.

2015-12-17  Pádraig Brady  <P@draigBrady.com>

	tests: avoid intermittent ulimit -v failures
	* init.cfg (get_min_ulimit_v_): Increase the determined
	virtual memory limit for the command by a page size
	to avoid alignment issues causing false failures for
	subsequent runs.
	* tests/misc/cut-huge-range.sh: Be defensive and match
	the cut invocations under test, more closely with the
	form used to determine the VM memory limit.

	This was noticed on i686 linux at:
	http://hydra.nixos.org/build/28990456

2015-12-17  Pádraig Brady  <P@draigBrady.com>

	build: ensure all files are writable in the tarball

	in tail.c.  Also give a link to *_SUPER_MAGIC definitions
	not in the standard linux/magic.h location.
	* NEWS: Mention that this file system is recognized.

2015-12-14  Pádraig Brady  <P@draigBrady.com>

	kill: add undocumented -L for compatibility
	procps, bash >= 4.4, and util-linux >= 2.23
	all have the -L option to output a table.

	* src/kill.c (main): Have -L synonymous with -t.
	Luckily there is no signal that begins with 'L'.

	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
	options.  Add "[+]" to clarify that NUM may optionally be preceded by
	this sign.  Remove the redundant explanation of the optional '+' prefix
	for NUM, as that is now clear from the option description above.

	build: avoid makeinfo unless required
	* doc/local.mk (constants.texi): Avoid calling makeinfo unless
	the constants derived from tail and shred have changed.

	doc: clarify descriptions for tr --squeeze-repeats
	* doc/coreutils.texi (uniq invocation): Fix the description of
	problematic input to say "blank lines" rather than "two or more

	state in examples where blank lines are deleted.
	Also add "deleting" to the menu item.
	* src/tr.c (usage): Improve the -s summary to say it always
	operates on the last specified SET.

	doc: provide an example for prefixing all tail output lines
	* doc/coreutils.texi (tail invocation): Provide an example using awk
	to convert tail ==> file <== headers to file: prefixes on each line.
	Suggested by Stephen Shirley.

	copy: fix copying of extents beyond the apparent file size
	fallocate can allocate extents beyond EOF via FALLOC_FL_KEEP_SIZE.
	Where there is a gap (hole) between the extents, and EOF is within
	that gap, the final hole wasn't reproduced, resulting in silent
	data corruption in the copied file (size too small).

	* src/copy.c (extent_copy): Ensure we don't process extents
	beyond the apparent file size, since processing and allocating
	those is not currently supported.
	* tests/cp/fiemap-extents.sh: Renamed from tests/cp/fiemap-empty.sh
	and re-enable parts checking the extents at and beyond EOF.

	maint: add a syntax check to avoid unstyled quoting
	* src/paste.c (main): Use our styled wrapper for quotearg_colon().
	* cfg.mk (sc_prohibit-quotearg): A new syntax check to avoid
	future uses of unstyled quotearg to one of the internal slots,
	and thus destined for diagnostic output.

	paste: avoid confusing backslash quoting in diagnostic
	* src/paste.c (main): Setting the quoting style to "escape"
	went against the intent of the comment about presenting
	doubled backslashes to the user.  Instead use "c-maybe"
	which is the only mode which avoids doubled backslashes,
	and provides protection against arbitrary control characters.
	* tests/misc/paste.pl: Adjust accordingly.

	all: avoid quoting file names when possible
	Quote file names using the "shell-escape" or "shell-escape-always"
	methods, which quote as appropriate for most shells,
	and better support copy and paste of presented names.
	The "always" variant is used when the file name is
	embedded in an error message with surrounding spaces.

	* cfg.mk (sc_error_shell_quotes): A new syntax check rule
	to suggest quotef() where appropriate.
	(sc_error_shell_always_quotes): Likewise for quoteaf().
	* src/system.h (quotef): A new define to apply shell quoting
	when needed.  I.E. when shell character or ':' is present.
	(quoteaf): Likewise, but always quote.
	* src/*.c: Use quotef() and quoteaf() rather than quote()
	where appropriate.
	* tests/: Adjust accordingly.

	when generating and checking checksums.  I.E. ensure a single line
	per file by starting the line with '\' for any file name containing '\n'
	and replacing those with "\\n".
	* NEWS: Move the item from changes in behavior to improvements,
	since this is no longer a backwards incompat change when
	processing stdout status messages.
	* tests/misc/md5sum.pl: Remove quotes from expected status output.
	* tests/misc/sha1sum.pl: Likewise.

2015-11-04  Pádraig Brady  <P@draigBrady.com>

	all: replace most uses of quotearg_colon() with quote()
	Related to commit v8.24-61-g6796698 this provides
	more consistent quoting, as quotearg_colon() defaults
	to "literal" quoting by default, while quote()
	provides appropriate quoting for diagnostics by default.

	* gl/modules/randread: Depend on quote module rather than quotearg.
	* gl/lib/randread.c: Used quote() not quotearg_colon().
	* src/: Likewise.
	* src/shred.c: Likewise. Also avoid unnecessary quoting
	introducing overhead when wiping names.
	* cfg.mk: Relax the matching expression to allow
	"qname" variables as used in shred.c to satisfy the check.
	* tests/: Adjust accordingly.
