	version 8.26
	* NEWS: Record release date.

	tests: fix false failure with spaces in $PWD
	* tests/misc/ptx-overrun.sh: Quote appropriately to avoid this
	recently added issue, noticed by `make taint-distcheck`.

	maint: avoid "make distcheck" failure without excess .deps directories
	* Makefile.am (my-distcheck): Add the -r option to xargs so that
	rmdir doesn't return an error when there are no extraneous .deps dirs.

	tests: fix ERRORs and false FAILs on some platforms
	* tests/misc/ls-time.sh: Skip the test rather than ERROR
	when `touch -m -d ...` fails (Hurd).
	* tests/tail-2/follow-stdin.sh: Avoid false FAILs by ignoring
	the variances in sterror output.

	head: fix processing of non-seekable input as seekable
	* src/head.c (elide_tail_bytes_file): Ensure we don't use
	st_size unless we've previously used seek() to determine
	the CURRENT_POS in the seekable file.
	This was seen to cause issue on FreeBSD 11 when the pipe
	buffer was filled with `yes | head --lines=-0`, in which
	case st_size was 64KiB while ST_BLKSIZE() was 4KiB.
	Reported by Assaf Gordon.

	same path that is given to mkdir().  The other path is not always valid
	wrt. current working directory.
	* src/mkdir.c (make_ancestor): Likewise.
	* NEWS: Mention the bug fix.

	ptx: fix an invalid heap reference with short --width
	* src/ptx.c (fix_output_parameters): Ensure line_width doesn't
	go negative, which can happen when the --width is less

	tests: fix false failure with ASAN in rm-readdir-fail
	* tests/rm/rm-readdir-fail.sh: ASAN correctly indicated
	that fts was writing to freed memory.  This was because
	we reused a single dirent in our readdir() test wrapper.
	Since fts was deallocating those dirents, we now get
	a new dirent for each call to our readdir wrapper.

	Specifically there would be invalid memory access
	and subsequent processing if the chunk to be extracted
	was beyond the initial amount read from file (which is
	currently capped at 128KiB).  This issue is not in a
	released version, only being introduced in commit v8.25-4-g62e7af0

	* src/split.c (bytes_chunk_extract): The initial_read != SIZE_MAX
	should have been combined with && rather than ||, but also this
	condition is always true in this function so remove entirely.
	* tests/split/b-chunk.sh: Add a test case.

	tail: fix checking of remoteness when not using inotify
	In recent commit v8.25-93-g7fc7206 we used the f->remote flag
	which wasn't set in all cases.  This was detected with
	ASAN giving this error when reading f->remote;
	  runtime error: load of value 190,
	  which is not a valid value for type '_Bool'

	* src/tail.c (fremote): Query the system even without inotify.
	(recheck): Always set f->fremote for valid files.

	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.
	Improved by Eric Blake.

	* tests/misc/printf-quote.sh: FreeBSD 11 was seen to treat
	\u0378 as a printable character.  Therefore change to

	representation because our printf implementation explicitly
	disallows \u0081 as input.

	ls: improve alignment of quoted names
	This provides better alignment when some names are quoted,
	which also provides better indication that quotes are not
	part of the name.

	* src/ls.c (align_variable_outer_quotes): A new variable
	set when ls is aligning columns (not using -m, non-zero -w),

	(quote_name_buf): Writes to buffer rather than FILE,

	ls: fix %%b format and precompute more
	The old code mishandled --time-spec='+%%b', as it misinterpreted
	the '%b' as being the month abbreviation.  Also, it mishandled
	the extremely unlikely case of a month abbreviation containing '%'.
	The performance part of this patch sped up 'ls' by about 1% on my
	little benchmark of 'ls -lR' on the source directory in the
	en_US.UTF-8 locale (Fedora 24 x86-64).
	* NEWS: Document the bug fix.
	* src/ls.c (first_percent_b, abformat_init): New static functions.
	(ABFORMAT_SIZE): New constant.
	(use_abformat): New static var.
	(abmon, required_mon_width): Remove these static vars.
	(abmon_init): Now accepts a pointer to abmon, and returns a boolean.
	All callers changed.  Reject month abbrs containing '%', as these
	would mess up strftime.  Simplify mbsalign result checking,
	since (size_t) -1 exceeds ABFORMAT_SIZE.
	(abformat_init, align_nstrftime): Precompute all 24 formats at
	startup, rather than computing a format for each time stamp.
	(decode_switches): Call abformat_init instead of abmon_init.
	(align_nstrftime): Accept recentness bool instead of format.
	All callers changed.
	* tests/misc/time-style.sh: Test for format with '%%b'.

	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.
	* src/system.h (getlogin, getuid, geteuid, getgrgid, getpwuid, ttyname):
	Add the parameter type to the declarations to avoid warnings when these
	backup declarations are used.

	* tests/misc/timeout-parameters.sh: Remove the overflow related
	to UINT_MAX as it's handled by the following case.  Change the

	tests: fix recent false failure due to a race
	* tests/cp/parent-perm-race.sh: This new race introduced in

	open() the source fifo.  Then the subsequent comparison of the
	destination file may fail due to the file being missing or empty.
	Previously `ls` generated output that was independent of `cp`.
	Now we must wait for `cp` to finish before inspecting the
	destination file that it wrote.

	date ls pr: fix time zone abbrs on SysV platforms
	The problematic code computed a struct tm in one time zone, and
	then printed it or converted it to a string in another.  To be
	portable the same time zone needs to be used for both operations.
	On GNU platforms this is not an issue, but incorrect output can be
	generated on System V style platforms like AIX where time zone
	abbreviations are available only in the 'tzname' global variable.

	* src/ls.c (long_time_expected_width, print_long_format):
	* src/pr.c (init_header):
	* src/stat.c (human_time): Use localtime_rz instead of localtime,
	so that the time zone information is consistent for both localtime
	and time-formatting functions like fprintftime and nstrftime.  For
	'stat' this change is mostly just a code cleanup but it also
	causes stat to also print nanoseconds when printing time stamps
	that are out of localtime range, as this is more consistent with
	what other programs do.  For programs other than 'stat' this fixes
	bugs with time zone formats that use %Z.
	* src/du.c, src/pr.c (localtz): New static var.
	(main): Initialize it.
	* src/du.c (show_date): New time zone argument, so that localtime

	Problem reported by Nelson H.F. Beebe in: http://bugs.gnu.org/22624
	Other problems also fixed: basically, the code got confused because

	* src/split.c (input_file_size): Now takes struct stat *, not just
	size.  Always store the first buffer.  All callers changed.  Treat
	/dev/zero as an infinitely-large file, both on GNU/Linux where
	fstat and lseek say its size is zero, and on GNU/Hurd where they

	(cwrite): Return true on success.
	(bytes_split): Don't try to read past EOF, and stop if a write fails.
	(lines_rr): Omit stray check for ignorable errno.

	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.

	df: prioritize mounts nearer the device root
	In the presence of bind mounts of a device, the 4th "mount root" field

	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
	minimum memory required to run a command simpler than in the real test
	run.  Use that limit plus a buffer there.  While at it, change to list
	of commands in the subshell to fail also if the beginning `ulimit -v`
	fails.

	* NEWS: Mention the change in behavior.

	base64: use stricter validation on wrap column
	* src/base64.c (main): Use the higher level xnumtoumax()

	string as the suffixes parameter so that invalid trailing
	characters are not allowed.  For example -w08 is now
	flagged as an error, rather than being interpreted as 0.
	A subsequent commit will further improve verification
	of numbers with leading zeros by dropping backwards compatibility

	/proc/self/mountinfo is still an advantage to get filtered items
	with accurate device patchs in chroots and with bind mounts.
	I.E. on older setups with static /etc/mtab, df will now
	bypass that to get the more accuracte and dynamic info.

	tests: avoid false failures with LD_PRELOAD=libasan.so.2
	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
	The tests below are adjusted so that workaround is not discarded.

	build: update to latest gnulib
	Mainly for -fsanitize=address and -fsanitize=undefined fixes

	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.

	* 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.

	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().

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.

	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.

2015-06-01  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,

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

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

	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.

	* bootstrap: Remove moot warning (resyncing with gnulib).
	* configure.ac (AC_PREREQ): Change to 2.69 (now 3 years old).

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

	tests: ln/hard-to-sym FAIL rather than ERROR when ln fails
	* tests/ln/hard-to-sym.sh: Only call framework_failure_ when ln

	copy: prefer our hardlink to symlink emulation on OS X 10.10
	* src/copy.c (CAN_HARDLINK_SYMLINKS): Don't enable use of linkat()
	on Darwin 14, as the gnulib fallback emulation there doesn't
	preserve ownership and timestamps etc.  This fixes a test failure
	in tests/cp/link-symlink.sh
	* tests/cp/link-deref.sh: Adjust accordingly.

2015-05-26  Pádraig Brady  <P@draigBrady.com>

	mkdir: fix -pZ with existing parent directories
	When the parent directory exists and has a different
	default context to the final directory, the context
	was incorrectly left as that of the parent directory.

	* src/mkdir.c (process_dir): Because defaultcon() is called for
	existing ancestors (as it must be to avoid races), then we must
	unconditionally call restorecon() on the last component due to
	the already documented caveat with make_dir_parents().
	Alternatively you could temp disable o->set_security_context
	around make_dir_parents(), but that would be subject to races.

	timeout: with --foreground don't send SIGCONT
	* src/timeout.c (cleanup): Don't send SIGCONT to the monitored program

2015-05-11  Pádraig Brady  <P@draigBrady.com>

	tail: consistently output all data for truncated files
	Generally if logs are truncated, they're truncated to 0 length,
	so output all existing data when our heuristic determines truncation.
	Note with inotify, truncate() and write() are often determined
	independently and so all data would be written if that was the case.

	* src/tail.c (check_fspec): Reset file offset to 0 upon truncation.
	(tail_forever): Likewise.
	(recheck): Add a FIXME for the related issue where tail may lose
	data due to tail discounting older log files too early.
	* tests/tail-2/truncate.sh: A new test.

	* NEWS: Mention the fix.

2015-05-11  Pádraig Brady  <P@draigBrady.com>

	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

	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 $pid needed.
	* tests/tail-2/inotify-rotate.sh: Use "fastpoll" options.
	* tests/tail-2/pid.sh: Use standard variable names.
	Add a `wait` on the background tails.
	* tests/tail-2/pipe-f2.sh: Likewise.
	* tests/tail-2/tail-n0f.sh: Likewise.
	* tests/tail-2/retry.sh: Use "fastpoll" options.
	* tests/tail-2/symlink.sh: Likewise.
	* tests/tail-2/wait.sh: Likewise.  Speedup by using sub second
	parameters to timeout(1).  Improve the part ensuring that
	-F never follows a renamed file.
	* tests/tail-2/infloop-1.sh: Remove invalid test.  tail(1) was not
	being passed the --pid=$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

	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

	wc: speedup counting of short lines
	Using a test file generated with:

	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.

	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

	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:

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.
	(main): With --write-error ignore SIGPIPE, and handle

	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.

	maint: avoid signed overflow warning with -O3

	     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.

	df: only suppress remote mounts of separate exports with --total
	* src/df.c (filter_mount_list): Separate remote locations are
	generally explicitly mounted, so list each even if they share
	the same remote device and thus storage.  However with --total
	keep the suppression to give a more accurate value for the
	total storage available.
	(usage): Expand on the new implications of --total and move
	it in the options list according to alphabetic order.

	df: ensure -a shows all remote file system entries
	commit v8.22-125-g9d736f8 printed placeholder "-" values
	for device names that didn't match the preferred device name
	for a particular mount point.  However that was seen to erroneously
	suppress values for aliased host names or exports, common with
	remote file systems.

	* src/df.c (me_for_dev): Rename from devname_for_dev() so that
	we can determine the remoteness as well as the name for the

	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
	run in the order where unlink(a) and unlink(b) are the last two system
	calls.  Therefore exit with an error code so that we avoid the potential
	data loss.

	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).

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

	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
	duplicate entries for the same file system is not limited to bind

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
	to options into alphabetical order.

	when NEWROOT is the old "/".
	Move down the chdir() call after the if-clause to ensure it is
	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.
	* doc/coreutils.texi (chroot invocation): Document the new option.
	Document that chroot(1) usually calls chdir("/") unless the new
	--skip-chdir option is specified.  Sort options.
	* NEWS (Changes in behavior): Mention the fix.

	sort: avoid undefined operation with destroying locked mutex
	This didn't seem to cause any invalid operation on GNU/Linux at least,
	but depending on the implementation, mutex deadlocks could occur.
	For example this might be the cause of lockups seen on Solaris:
	http://lists.gnu.org/archive/html/coreutils/2013-03/msg00048.html

	This was identified with valgrind 3.9.0 with this setup:

	  seq 200000 > file.sort
	  valgrind --tool=drd src/sort file.sort -o file.sort

	With that, valgrind would _intermittently_ report the following:

	build: adjust new rule not to depend on bash-4.x
	* man/local.mk (man/dynamic-deps.mk): Use the same code to

	Using the more concise "name=$${man:4: -2}" is not portable enough.

	build: support building all tools in a single binary
	Add the --enable-single-binary option to the configure file.
	When enabled, this option builds a single binary file containing
	the selected tools.  Which tool gets executed depends on the value
	of argv[0] which can be set implicitly through symlinks to the
	single program.

	This setup reduces significantly the size of a complete coreutils
	install, since code from lib/libcoreutils.a is not duplicated in
	every one of the more than 100 binaries.  Runtime overhead is
	increased due to more dynamic libraries being loaded, and extra
	initialization being performed for all utils.  Also initially
	a larger binary is loaded from storage, though this is usually
	alleviated due to caching and lazy mmaping of unused blocks,
	and in fact the single binary should have better caching
	characteristics.

	Comparing the size of the individual versus single binary on x86_64:
	  $ cd src
	  $ size coreutils
	  $ size -t $(../build-aux/gen-lists-of-programs.sh --list-progs |
	              grep -Ev '(coreutils|libstdbuf)') | tail -n1
	     text    data     bss     dec     hex filename
	  1097416    5388   88432 1191236  122d44 src/coreutils
	  4901010  124964  163768 5189742  4f306e (TOTALS)

	Storage requirements are reduced similarly:
	  $ cd src
	  $ du -h coreutils
	  $ du -ch $(../build-aux/gen-lists-of-programs.sh --list-progs |
	             grep -Ev '(coreutils|libstdbuf)') | tail -n1
	  1.2M    coreutils
	  5.3M    total

	When installing, the makefile will create either symlinks or
	shebangs based on the --enable-single-binary setting, for
	each configured tool. In this way, all the tools are still
	callable individually, but they are all implemented by the same
	"coreutils" binary installed on the same directory.

	cut: restore special case handling of -f with -d$'\n'
	commits v8.20-98-g51ce0bf and v8.20-99-gd302aed changed cut(1)
	to process each line independently and thus promptly output
	each line without buffering.  As part of those changes we removed
	the special handling of --delimiter=$'\n' --fields=... which
	could be used to select arbitrary (ranges of) lines, so as to
	simplify and optimize the implementation while also matching the
	behavior of different cut(1) implementations.

	However that GNU behavior was in place for a long time, and
	could be useful in certain cases like making a separated list like
	`seq 10 | cut -f1- -d$'\n' --output-delimiter=,` although other tools
	like head(1) and paste(1) are more suited to this operation.
	This patch reinstates that functionality but restricts the
	"line behind" buffering behavior to only the -d$'\n' case.

	We also fix the following related edge case to be more consistent:

	  before> printf "\n" | cut -s -d$'\n' -f1- | wc -l
	  2
	  before> printf "\n" | cut    -d$'\n' -f1- | wc -l

	stdbuf: support compilers other than __GNUC__
	__SUNPRO_C >= 0x590 /*12.0*/ supports __attribute((constructor))
	required by stdbuf, so use a more direct check for this.

	Note ensure that --libexecdir is set to the appropriate
	install location for libstdbuf.so so that stdbuf works
	when installed on the system like it does when running
	tests in the build directory.

	* configure.ac (stdbuf_supported): Use a test prog to determine support.
	* src/libstdbuf.c (stdbuf): Define appropriately for non GCC compilers,
	and provide early feedback (compilation warning) if trying to compile
	libstdbuf without the necessary support.
	* src/stdbuf.c (set_LD_PRELOAD): Add a note on having stdbuf
	look for libstdbuf.so in the default lib search path.
	* cfg.mk (sc_prohibit-gl-attributes): Adjust so we can exclude
	libstdbuf.so from prohibiting '__attribute', since we want
	this form to avoid silently eliding this required attribute on non GCC.

	chroot: with --userspec clear root's supplemental groups
	It's dangerous and confusing to leave root's supplemental
	groups in place when specifying other users with --userspec.
	In the edge case that that is desired one can explicitly
	specify --groups.

	Also we implicitly set the system defined supplemental groups
	for a user.  The existing mechanism where supplemental groups
	needed to be explicitly specified is confusing and not general
	when the lookup needs to be done within the chroot.

	Also we extend the --groups syntax slightly to allow clearing
	the set of supplementary groups using --groups=''.

	* src/chroot.c (setgroups): On systems without supplemental groups,
	clearing then is a noop and so should return success.
	(main): Lookup the primary GID with getpwuid() when just a numeric
	uid is specified, and also infer the USERNAME from this call,
	needed when we're later looking up the supplemental groups for a user.
	Support clearing supplemental groups, either implicitly for
	unknown users, or explicitly when --groups='' is specified.
	* tests/misc/chroot-credentials.sh: Various new test cases
	* doc/coreutils.texi (chroot invocation): Adjust for the new behavior.
	* NEWS: Mention the change in behavior.

2014-05-16  Pádraig Brady  <P@draigBrady.com>

	chroot: don't chdir() if not changing root
	This allows chroot to be used as a light weight tool
	to change user identification for a command,
	while not changing the current working directory.
	It also makes `chroot / true` consistently succeed on
	all platforms for non root users.

	* src/chroot.c (main): If the same root is specified. i.e. '/'
	then don't change the current working directory, and avoid the
	overhead of the other redundant calls.
	* tests/misc/chroot-fail.sh: Remove failure guard previously
	needed on some systems.  Also add an explicit case to ensure
	we don't change directory.

	df: ignore non file system entries in /proc/mounts
	Linux with network namespaces contains entries in /proc/mounts like:
	  proc net:[4026532464] proc rw,nosuid,nodev,noexec,relatime 0 0
	resulting in a failure to stat 'net:[...]', inducing a warning

	df: fix handling of symlinks in mount list
	The symlink handling in commit v8.21-172-g33660b4 was incomplete
	in the case where there were symlinks in the mount list itself.
	For example, in the case where /dev/mapper/fedora-home was in the
	mount list and that in turn was a symlink to /dev/dm-2, we have:

	  before> df --out=source /dev/mapper/fedora-home
	          devtmpfs

	  after > df --out=source /dev/mapper/fedora-home
	          /dev/mapper/fedora-home

	* src/df.c (get_disk): Compare canonicalized device names from
	the mount list.  Note we still display the non canonicalized name,
	even if longer, as we assume that is the most representative.
	* tests/df/df-symlink.sh: This could theoretically fail on some systems
	depending on the content of the mount list, but adjust to fail on any
	system where symlinks are present in the mount list for the current dir.

2014-05-13  Pádraig Brady  <P@draigBrady.com>

	df: also deduplicate virtual file systems
	* src/df.c (filter_mountlist): Remove the constraint that
	a '/' needs to be in the device name for a mount entry to
	be considered for deduplication.  Virtual file systems also
	have storage associated with them (like tmpfs for example),
	and thus need to be deduplicated since they will be shown
	in the default df output and subject to --total processing also.
	* test/df/skip-duplicates.sh: Add a test to ensure we deduplicate
	all entries, even for virtual file systems.  Also avoid possible
	length operations on many remote file systems in the initial
	check of df operation.  Also avoid the assumption that "/root"
	is on the same file system as "/".
	* NEWS: Mention the change in behavior.

	tests: fix spurious failure with leading spaces in file names
	* tests/ls/stat-vs-dirent.sh: This test lists all parent directories,
	and would spuriously fail if any of those had a file name with a
	leading space as the first entry.  There is only ever a single space
	between the right aligned inode number and the file name, so
	process accordingly.

	The initial report and high level analysis were from Jim Meyering...

	  "The underlying problem is that swallow_file_in_memory()
	  is setting the contents of the global text_buffer for the first file,
	  then updating it (clobbering old value) for the second file.
	  Yet, some pointers to the initial buffer have been squirreled away
	  and later, one of them (keyafter) is presumed to point into
	  the new "text_buffer", which it does not.  The subsequent
	  SKIP_WHITE_BACKWARDS use backs up "cursor" and goes out of bounds."

	* src/ptx.c (text_buffers): Maintain references for the limits of each
	buffer corresponding to each file, rather than just the last processed.
	(struct OCCURS): Add a member to map back to the corresponding file.
	Note normally this could be computed from the "reference" member
	rather than needing the extra storage, however this is not possible

	(dopass): ... here so we can avoid enabling it for these small
	initial writes.  It's better to retry direct I/O for each pass
	anyway to handle the case where direct I/O is disabled for only
	the last portion of a file when the size is not a multiple of
	the block size.  Note we don't avoid the sync for the initial

	split: avoid unnecessary input buffering
	Input buffering is best avoided because it introduces
	delayed processing of output for intermittent input,
	especially when the output size is less than that of
	the input buffer.  This is significant when output
	is being further processed which could happen if split
	is writing to precreated fifos, or through --filter.

	If input is arriving quickly from a pipe then this will
	already be buffered before we read it, so fast arriving
	input shouldn't be a performance issue.

	chroot: improve --userspec and --groups look-up
	- Support arbitrary numbers in --groups, consistent with

	- Avoid look-ups entirely for --groups items with a leading '+'
	- Support names that are actually numbers in --groups
	- Ignore an empty --groups="" option for consistency with --userspec
	- Look up both inside and outside the chroot with inside taking
	  precedence.  The look-up outside may load required libraries
	  to complete the look-up inside the chroot.  This can happen for
	  example with a 32 bit chroot on a 64 bit system, where the
	  32 bit NSS plugins within the chroot fail to load.

	* src/chroot.c (parse_additional_groups): A new function refactored

	Prompted by a test framework failure of tests/mkdir/p-acl.sh on armv7l:
	The previous test for a working setfacl was not sufficient in some

	tests: avoid FP failure when cp fails for /proc/cpuinfo
	On emulated aarch64 systems like in the qemu-based OpenBuildService
	of openSUSE, cp fails to copy /proc/cpuinfo because the inode number
	changes between the initial stat() call and copying the file:

	  $ cp /proc/cpuinfo exp
	  cp: skipping file '/proc/cpuinfo', as it was \
	  replaced while being copied

	* tests/cp/proc-zero-len.sh: When cp fails, check on the above
	error message to skip the test.

	tests: avoid unlikely deadlock in dd/no-allocate on some shells
	* test/dd/no-allocate.sh: Use 'wait' to ensure we don't have
	multiple writers to the fifo, which was seen to trigger
	a very hard to reproduce deadlock with make -j20 on solaris.
	Also avoid writing to the fifo with the shell; instead using dd.
	(check_dd_seek_alloc): A new function refactored from the various
	cases, which are now constructed from function parameters.

	tests: restrict cp --link inode comparisons to compatible systems
	* tests/cp/link-deref.sh: On systems were cp can't determine if
	gnulib linkat() emulation might create a symlink instead of a hardlink
	to a symlink, copy.c will create a symlink to the symlink so that
	it has more control over its metadata.  Also even if the system
	supports this operation, the particular file system under test may not.
	So avoid the hardlinked symlink verification in these cases.
	This fixes a false failure on aix, solaris and freebsd.

	build: default to avoiding openssl system libraries

	tests: fix false failure on systems without /dev/stdin
	* tests/rm/interactive-once.sh: Ensure the expected output

2013-12-09  Pádraig Brady  <P@draigBrady.com>

	tests: fix false failure due to gdb inline function handling
	Inline functions are awkward to breakpoint as mentioned at:
	https://sourceware.org/bugzilla/show_bug.cgi?id=10738
	The normal case here was for the breakpoint on the inline function
	to fail, resulting in a 10s delay before skipping the test.
	However on GCC 4.7.2 on ppc64 at least it was seen that
	the test failed erroneously due to the breakpoint being successfully
	set on an "out of line" function, but an inline function was
	actually being called.

	* tests/tail-2/inotify-race.sh: Switch to a line based breakpoint,
	rather than a symbol base one, which avoids issues with breakpoints
	on inline functions.  Also skip_ on the initial breakpoint check
	in case the breakpoint is not traversed which would be the case
	on remote file systems for example.

2013-12-09  Pádraig Brady  <P@draigBrady.com>

	tail: use consistent diagnostics with and without inotify
	* src/tail.c: With inotify, when a file is initially absent,
	we fstat(-1) for that file spec, thus recording an errnum of EBADF,
	which caused the "has become accessible" diagnostic to be issued,
	when the file first appears.  Instead we avoid the fstat(-1) and
	thus emit the more natural and consistent "has appeared" diagnostic.
	* tests/tail-2/retry.sh: Use the new diagnostic which also causes
	this test to pass on systems without inotify.

	* tests/cp/link-deref.sh: This was seen to cause an issue
	with dash v0.5.6 at least, so change to a simpler expression.

	tests: fix false failure on platforms using newfstatat
	* tests/ls/stat-free-color.sh: Add newfstatat to the list
	of syscalls to trace.  Also add all "stat" syscalls to the
	list of syscalls that we verify that strace supports.
	Also only create a single dangling symlink to check, since
	we already only check for a single "stat" call.

	This could trigger on SELinux systems where we build --qithout-selinux
	or where the SELinux development libraries are not installed.

	* init.cfg (require_selinux_enforcing_): Call require_selinux_()
	to determine if the current build supports SELinux.  This avoids
	a false failure in tests/mkdir/selinux.sh where only mkdir would
	determine that SELinux was disabled and thus ignore invalid contexts.
	(require_selinux_): Refactor a little to distinguish whether it's

	selinux: adjust utils to run restorecon with -Z
	cp, mv, install, mkdir, mkfifo, mknod are adjusted so that:
	 -Z no longer accepts an argument.
	 -Z or --context without an argument do not warn without SELinux.
	 --context with an argument will warn without SELinux.

	* src/local.mk: Reference the new selinux module where required.
	* src/system.h: Make the argument to --context optional.
	* src/mkdir.c: Likewise.  Also handle the SMACK case for --context.
	Note we currently silently ignore -Z with SMACK.
	* src/mkfifo.c: Likewise.
	* src/mknod.c: Likewise.
	* src/install.c: Likewise.  Note install(1) by default already
	set the context for target files to their system default,
	albeit with an older method.  Use the -Z option to select between
	the old and new context restoration behavior, and document
	the differences and details for how context restoration
	is done in new and old methods, with a view disabling the
	old method entirely in future.
	* src/cp.c: Make the argument to --context optional.
	Note -Z implies --no-preserve=context.  I.E. -Z overrides
	that aspect of -a no matter what order specified.
	(struct cp_options): Document the context handling options.
	(main): Check/adjust option combinations after all
	options are processed, to both simplify processing
	and to make handling independent of order of options
	on the command line.  Also improve the diagnostics
	from a failed call to setfscreatecon().
	(set_process_security_ctx): A new function,
	refactored to set the default context from the source file,
	or with the type adjusted as per the system default for
	the destination path.
	(set_file_security_ctx): A new function refactored to
	set the security context of an existing file, either based on
	the process context or the default system context for a path.
	(copy_internal): Use the refactored functions to simplify
	error handling and consistently fail or warn as needed.
	(copy_reg): Likewise.
	(copy_internal): With --preserve=context, also copy
	context from non regular files.  Note for directories this may
	impact the copying of subsequent files to that directory?
	(copy_attr): If we're handling SELinux explicitly,
	then exclude to avoid the redudant copy with --preserve=context,
	and the problematic copy with -Z.  Note SELinux attribute exclusion
	also now honors cp -a --no-preserve=context.  Note there was a
	very small window over 10 years ago, where attr_copy_file was
	available, while attr_copy_check_permissions was not, so we
	don't bother adding an explicit m4 check for the latter function.
	* src/mv.c: Support --context, but don't allow specifying an argument.
	* src/chcon.c: Adjust a comment to be specific to SELinux.
	* src/runcon.c: Likewise.
	* src/copy.c: Honor the context settings to "restorecon" as appropriate.

	* tests/cp/cp-a-selinux.sh: Augment this test with cases
	testing basic -Z functionality, and also test the various

	* tests/mkdir/restorecon.sh: Add a new test for the
	more involved mkdir -Z handling, since the directory changing
	and non existent directories need to be specially handled.
	Also check the similar but simpler handling of -Z by mk{nod,fifo}.

	selinux: a new module implementing "restorecon" functionality
	* src/selinux.c: A new module implementing "restorecon" functionality.
	There are two main functions to adjust the type of the referenced
	file system item.  defaultcon() will setup the process context so
	that new items will have the required context without races.  This is
	the preferred method.  For existing files, the equivalent restorecon()
	is available which has two modes.  With the "local" parameter set to
	false, restorecon() will adjust the type according to the system
	configuration for that file, and set to true will update the context

	shred: provide --remove methods to avoid excessive syncing
	A sync operation is very often expensive.  For illustration
	I timed the following python script which indicated that
	each ext4 dir sync was taking about 2ms and 12ms, on an
	SSD and traditional disk respectively.

	  import os
	  d=os.open(".", os.O_DIRECTORY|os.O_RDONLY)
	  for i in range(1000):
	     os.fdatasync(d)

	So syncing for each character for each file can result
	in significant delays.  Often this overhead is redundant,
	as only the data is sensitive and not the file name.
	Even if the names are sensitive, your file system may
	employ synchronous metadata updates, which also makes
	explicit syncing redundant.

	* tests/misc/shred-remove.sh: Ensure all the new parameters
	actually unlink the file.

	parameters to the --remove option.

	base64: improve encoding I/O efficiency
	Since the I/O overhead is significant to the relatively
	simple processing done by this utility, use fputs() rather
	than fputc() to output '\n'.
	Time to process a 100MiB file was measured to
	decrease from 0.417s to 0.383s, i.e. an 8% improvement.

	Related to these changes, is a processing improvement in
	gnulib, which increases throughput by 60% when processing
	full buffers, which improves processing of a 100MiB file
	with standard wrapped output, down to 0.256s.
	http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=commit;h=43fd1e7b

	Also increase the encoding buffer size from 3 to 30KiB.
	This was seen to give a further 8% improvement, taking
	processing time down to 0.235s in the wrapped output case.
	The decoding size buffer is not adjusted,
	due to the noted caveat with --ignore-garbage.

	* src/base64.c (BLOCKSIZE): Split into ENC_ and DEC_ variants,
	with the former increased from 3KiB to 30KiB.
	(wrap_write): Use the simpler fputc() rather than fputs()
	to output the '\n' character.  Also check against EOF
	rather than < 0 for errors.
	(do_encode): Likewise.
	* NEWS: Mention the large increase in performance, which
	with the I/O improvements in coreutils and the processing
	improvement in gnulib, amount to about a 60% throughput increase.

	* src/shred.c (dopass): Exit early to avoid redundant heap

	shred: fix direct I/O failures for last write to file
	Since direct I/O is now enabled with commit v8.21-139-gebaf961
	we must handle the case where we write an odd size at the
	end of a file (with --exact), or we specify an odd --size that
	is larger than 64KiB, or in the very unlikely case of a device
	with an odd size.  This issue was present since direct I/O
	support was first added in v5.3.0, but latent since v6.0.
	Theoretically this could have also been an issue after that on
	systems which didn't have alignment constraints, but did have
	size constraints for direct I/O.

	* src/shred.c (dopass): On the first pass for a file, always
	retry a write that fails with EINVAL, so we handle direct I/O
	failure at either the start or end of the file.  Adjust the comment
	as the original case is out of date and implicitly handled
	by this more general fix.
	* tests/misc/shred-exact.sh: Add a test case.

	shred: enable direct I/O when possible
	Commit v5.92-1057-g43d487b introduced a regression
	in coreutils 6.0 where it removed the page alignment
	of the buffer to write, thus disabling direct I/O.
	We want to use direct I/O when possible to avoid
	impacting the page cache at least, as we know we don't
	want to cache the data we're writing.

	* src/shred.c (dopass): Allocate the buffer on the heap,
	while using a more general calculation to allow to have
	the output size independent from the fillpattern() size
	constraint of a multiple of 3.  Also we dispense with the
	union as it's no longer needed given we're aligning on
	a page boundary and thus don't need to explicitly handle

	maint: avoid patching help2man
	Commit cde1ea0e separated the coreutils-specific patches from help2man.
	Most changes had been made to accommodate to the coreutils style guide,
	i.e., to avoid syntax-check failures like sc_long_lines.
	Yet 2 changes had to be put into the patch help2man.diff.
	But this added the dependency to patch(1) in distribution builds.
	Incidentally, the 2 remaining parts of the patch can easily be
	done outside of help2man.  Therefore, this commit partly reverts
	the recent separation of help2man into 'help2man.in' and
	'help2man.diff', and instead uses the original help2man script.

	* man/help2man.in: Rename to ...
	* man/help2man: ... this file.
	* man/help2man.diff: Remove.
	* man/local.mk (mandeps): Remove man/help2man.

	Furthermore, use an sed pattern to remove the sentence starting
	with "For complete documentation".
	* .gitignore (/man/help2man): Remove entry.

	'man/help2man.diff' and 'man/help2man.in' by 'man/help2man'.

	maint: update help2man to 1.43.3
	Instead of diverging further from the upstream GNU help2man project
	(http://www.gnu.org/software/help2man/), hold a copy of the original
	script and keep track of our changes in a separate patch file.

	The man pages created with the new version show the following,
	non-invasive differences:
	a) command options in the EXAMPLE sections are no longer in bold format,
	b) file names are underlined now consistently.

	* man/help2man: Rename to ...
	* man/help2man.in: ... this file, and update content from the
	upstream GNU help2man project.
	* man/help2man.diff: Add patch file for help2man to remove the
	sentence "For complete documentation ..." (see commit 5d4f09d8),
	and to emit "info coreutils 'PROG invocation'" into the man
	pages (77abf69a).
	* man/local.mk (mandeps): Add help2man to the dependencies of
	the man pages.
	(man/help2man): Add rule to generate this script from the upstream
	help2man.in file and the help2man.diff patch.
	* .gitignore: Add man/help2man as it is no longer version controlled.
	* cfg.mk (sc_long_lines): Exempt help2man.in from this check.
	(sc_po_check): Likewise.
	(sc_space_tab): Likewise.
	(sc_trailing_blank): Exempt man/help2man.diff from this check.
	(sc_prohibit_tab_based_indentation): Instead of help2man, now exempt
	both help2man.in and help2man.diff from this test.
	* .x-update-copyright: Add new file and add the above new help2man
	files as well as the COPYING file.

	ls: fix possible incorrect exit status when recursing directories
	If there is an error reading a directory that was referenced
	through recursion, rather than directly on the command line,
	then exit with the "less serious" exit code, rather than the
	"serious" exit code reserved for command line arguments.
	This issue was introduced in commit v5.2.1-1908-gb58dea5

	* src/ls.c (print_dir): Ensure that the command_line_arg param
	is false for directories being recursed into.
	* NEWS: Mention the bug fix.
	Fixes http://bugs.gnu.org/15249

2013-09-01  Pádraig Brady  <P@draigBrady.com>

	maint: update out of date confusing comments
	* src/copy.c (copy_internal): Change mention of the removed --reply=no
	option, to the similar in this context --no-clobber.
	* src/sort.c: SI and IEC suffixes can now be mixed when --human-numeric.

2013-08-29  Pádraig Brady  <P@draigBrady.com>

	df: fix "blocks" translation in header
	* src/df.c (get_header): Get the translation of "blocks" here,

	tests: fix another test failure in test/du/inodes.sh
	Prompted by the continuous integration build failure at:
	http://hydra.nixos.org/build/5584121

	du(1) uses the first file object of the two test files linked to the
	same inode, 'd/f' and 'd/h', whatever the system returns first.
	Use 'd/f' in both the expected and the actual output.

	* test/du/inodes.sh: Change the expected output as described above
	when returning the --all directory entries (without -l).  Also replace
	the name of the hardlink 'd/h' by 'd/f' in the actual output.

2013-07-28  Paul Eggert  <eggert@cs.ucla.edu>

2013-07-28  Bernhard Voelker  <mail@bernhard-voelker.de>

	maint: cleanup compare calls in test/du/inodes.sh
	* test/du/inodes.sh: In the cases where compare() fails, that function
	would show the unified diff automatically.  Therefore, remove the
	excess "cat out".
	In the cases where expecting an empty file, use compare() again
	rather than the simpler "test -s" because possible error reports
	will then include the file's content for the same reason as above.

2013-07-28  Pádraig Brady  <P@draigBrady.com>

	maint: avoid clang static analysis issues in csplit
	* src/csplit.c (find_lines): Assert that load_buffer() updates the
	global buffers, thus "b" will be non NULL, thus suppressing subsequent
	NULL pointer derefence warnings.
	(process_regexp): Avoid a redundant assignment of the "line" pointer.
	(process_line_count): Likewise.  Also reduce the "line" pointer scope.

	tests: fix intermittent failure in test/du/inodes.sh
	Prompted by the continuous integration build failure at:
	http://hydra.nixos.org/build/5582213

	* test/du/inodes.sh: Due to undefined order in returned directory
	entries, the expected output might not match, so sort both expected
	and actual output when returning --all directory entries.
	Also use a simpler test for ensuring no errors are output.

2013-07-27  Bernhard Voelker  <mail@bernhard-voelker.de>

	du: add --inodes option
	This new option can be used to find directories with a huge
	amount of files.  The GNU find utility has the printf format
	"%h" which prints the number of entries in a directory, but
	this is non-cumulative and doesn't handle hard links.

	* src/du.c (struct duinfo): Add new member for counting inodes.
	(duinfo_init): Initialize inodes member with Zero.
	(duinfo_set): Set inodes counter to 1.
	(duinfo_add): Sum up the 2 given inodes counters.
	(opt_inodes): Add new boolean flag to remember if the --inodes
	option has been specified.
	(INODES_OPTION): Add new enum value to be used ...
	(long_options): ... here.
	(usage): Add description of the new option.
	(print_size): Pass inodes counter or size to print_only_size,
	depending on the inodes mode.
	(process_file): Adapt threshold handling: with --inodes, print or
	elide the entries according to the struct member inodes.
	(main): Add a case for accepting the new INODES_OPTION.
	Print a warning diagnostic when --inodes is used together with the
	option --apparent-size or -b.
	Reset the output_block_size to 1 ... and thus ignoring the
	options -m and -k.
	* tests/du/inodes.sh: Add a new test.
	* tests/local.mk (all_tests): Mention it.
	* doc/coreutils.texi (du invocation): Document the new option.
	* NEWS: Mention the new option.

	mv: replace empty directories in cross file system move
	src/copy.c (copy_internal): Use rmdir() rather than unlink()

	* tests/mv/part-rename.sh: Augment with various combinations.
	* NEWS: Mention the bug fix.

2013-07-22  Bernhard Voelker  <mail@bernhard-voelker.de>

	maint: make some shell and perl scripts executable in 'tests/'
	Some newer test scripts - partially ones from me - are not executable.
	It does not seem to be a problem, but for consistency and to avoid
	future problems on unusual platforms or shells change the permissions
	by adding the executable bit.

	* cfg.mk (sc_tests_executable): Add new syntax-check rule to ensure
	that all test scripts are executable.
	* tests/df/df-output.sh: Change file mode from 644 to 755.

	rm: output number of arguments at the interactive prompt
	Include the number of arguments which rm received in the "Remove all
	arguments?" prompt.  This is useful in the, presumably, common case
	where the arguments were not provided by hand, but instead were the
	result of various shell expansions.  A simple, if somewhat contrived,
	example (assuming rm is aliased to rm -I) could be:

	  rm * .o

	where the prompt "Remove 120 arguments?" is more likely to make
	the user catch the problem.

	* src/rm.c (main): Include correctly pluralized n_files
	in the output message.  Also remove the now redudant "all".
	* tests/rm/interactive-always.sh: Adjust to the new prompt.
	* tests/rm/interactive-once.sh: Likewise.

	* tests/dd/misc.sh: Ensure the diagnostic about
	being unable to skip past the end of input is suppressed.

	* tests/tail-2/retry.sh: Ensure the 'out' file is truncated,
	as it's used to arbitrate the run order of commands.
	Relying on the truncation in the background tail command
	is racy because the truncation can occur after the fork
	of the background shell and thus wait4lines would not wait
	for output to occur in 'out', which would mean that the
	'missing' file could be populated by the time tail(1)
	gets to process it.

	cut: make memory allocation independent of range width
	The current implementation of cut, uses a bit array,
	an array of `struct range_pair's, and (when --output-delimiter
	is specified) a hash_table.  The new implementation will use
	only an array of `struct range_pair's.
	The old implementation is memory inefficient because:
	 1. When -b with a big num is specified, it allocates a lot of
	    memory for `printable_field'.
	 2. When --output-delimiter is specified, it will allocate 31 buckets.
	    Even if only a few ranges are specified.

	Note CPU overhead is increased to determine if an item is to be printed,
	as shown by:

	$ yes abcdfeg | head -n1MB > big-file
	$ for c in with-bitarray without-bitarray; do
	    src/cut-$c 2>/dev/null
	    echo -ne "\n== $c =="
	    time src/cut-$c -b1,3 big-file > /dev/null
	  done

	== with-bitarray ==
	real    0m0.084s
	user    0m0.078s
	sys     0m0.006s

	== without-bitarray ==
	real    0m0.111s
	user    0m0.108s
	sys     0m0.002s

	Subsequent patches will reduce this overhead.

	* src/cut.c (set_fields): Set and initialize RP
	instead of printable_field.
	* src/cut.c (is_range_start_index): Use CURRENT_RP rather than a hash.
	* tests/misc/cut.pl: Check if `eol_range_start' is set correctly.

	tail: exit following by descriptor when no tailable file left
	As a side effect of the previous commit which fixes 'tail -f --retry'
	to wait for a file to appear, tail would not exit when the last file
	appears untailable and gives up on this file.
	This can happen, for example, when the argument file name appears
	as directory.  Tail sets the 'ignore' flag of this file to true,
	but instead of exiting the program, tail would continue the loop.

	* src/tail.c (any_live_files): Change the function to return true
	if any of the files is still tailable or if tail should continue to
	try to check again.
	(tail_forever): Change the condition to break the loop in the
	"no files remaining" case, because now any_live_files() will care
	about it, as mentioned above.

	then reset reopen_inaccessible_files to false.
	* tests/tail-2/retry.sh: Add test case.

2013-04-20  Bernhard Voelker  <mail@bernhard-voelker.de>

	tail: let -f --retry wait for inaccessible files
	The --retry option is indeed useful for both following modes
	by name and by file descriptor.  The difference is that in the
	latter case, it is effective only during the initial open.

	As a regression of the implementation of the inotify support,
	tail -f --retry would immediately exit if the given file is
	inaccessible.

	* src/tail.c (usage): Change the description of the --retry option:
	remove the note that this option would mainly be useful when
	following by name.
	(main): Change diagnosing dubios uses of --retry option:
	when the --retry option is used without following, then issue
	a warning that this option is ignored; when it is used together
	with --follow=descriptor, then issue a warning that it is only
	effective for the initial open.
	Disable inotify also in the case when the initial open in tail_file()
	failed (which is the actual bug fix).

	maint: choose editor in the commit-msg git hook the same way git does
	Git honours the GIT_EDITOR environment variable, the "core.editor" Git
	configuration variable, and the EDITOR environment variable (in that
	order, and defaulting to "vi" if none of them is set) to decide which
	editor should be invoked for the user when he has to or want to edit
	his commit message.

	However, our commit-msg hook, when invoking an editor on behalf of the
	user to allow him to fix a non-policy-complaint commit message, only
	honoured the EDITOR environment variable.  To avoid potential annoying
	inconsistencies, we should really use the same logic used by Git in the
	selection of the editor.  Luckily, we don't have to duplicate this
	logic (that would be brittle in the long term), as we can rely on the
	"git var" command, designed exactly to be used in situations like this.

	* scripts/git-hooks ($editor): Adjust definition.

2013-02-18  Stefano Lattarini  <stefano.lattarini@gmail.com>

	maint: don't reset PATH in the commit-msg git hook
	I have a custom 'editor' script in ~/bin, and a system-provided
	'editor' program in /usr/bin (on Debian, this is a link set up the
	"debian alternatives" subsystem).  My '$EDITOR' and '$GIT_EDITOR'
	variables are set simply to 'editor' (no absolute path), which I
	expect should point to my 'editor' script, since ~/bin precedes
	/usr/bin in my PATH definition.  But the 'commit-msg' hook used in
	coreutils unconditionally resets its PATH to '/bin:/usr/bin', which
	causes it to call the "wrong" editor (the one in /usr/bin, not the
	one in ~/bin) when it makes me update a botched commit message.

	* scripts/git-hooks: Don't reset $ENV{PATH} to '/bin:/usr/bin',
	which was only done to avoid failure when enabling Perl's taint
	checking.

	maint: consolidate developer debug messages
	Both factor and numfmt recently introduced debug messages
	for developers, enabled by --verbose and ---devdebug respectively.
	There were a few issues though:
	 1. They used different mechanisms to enable these messages.
	 2. factor used --verbose which might be needed for something else
	 3. They used different methods to output the messages,
	    and numfmt used error() which added an unwanted newline
	 4. numfmt marked all these messages for translation and factor
	    marked a couple.  We really don't need these translated.
	So we fix the above issues here while renaming the enabling
	option for both commands to ---debug (still undocumented).

	* src/factor.c (verbose): Rename to dev_debug and change from int to
	bool as it's just a toggle flag.
	(long_options): Rename --verbose to ---debug.
	* src/system.h (devmsg): A new inline function to output a message
	if enabled by a global dev_debug variable in the compilation unit.
	* src/numfmt.c: Use devmsg() rather than error().
	Also remove the translation tags from these messages.
	Also change debug flag to bool from int.
	* tests/misc/numfmt.pl: Adjust for the ---devdebug to ---debug change.
	* cfg.mk (sc_marked_devdiagnostics): Add a syntax check to ensure
	translations are not added to devmsg calls.

	tests: remove test case du/slink
	This test tried to ensure that not all symlinks (across all
	file system types) have Zero size and refers to a change
	in system.h from 2002-08-31 (commit SH-UTILS-2_0_15-55-g62808a7).
	The test used to do this by working on symlinks to long file
	names.  This assumption is dependant on the underlying file
	system, and in some environments like XEN does not even work
	on file systems known to work otherwise.

	The test for dereferencing and no-dereferencing symlinks is
	already covered by other tests (du/deref.sh, du/deref-args.sh,
	and du/no-deref.sh).  Therefore, remove it.

	* tests/du/slink.sh: Remove file.
	* tests/local.mk (all_tests): Remove the above test.

	factor: apply a more general fix to enable correct assembly
	In addition to the previous 64 bit guards we've placed in longlong.h
	there are additional _LP64 guards required for mips with -mcpu >= 3,
	to avoid a build failure (http://bugs.gnu.org/13353) and on sparc
	with -mcpu >= v9 in 32 bit mode where for example,
	`factor 2123123123123123123123` would go into an infinite loop.

	Since factor.c currently operates on uintmax_t, we restrict the use
	of the assembly in longlong.h to when 'long' has the same width, to
	provide a more general guard for this code.

	* src/factor.c: Restrict the use of longlong.h assembly code,
	to when the width of intmax_t == long.
	* src/longlong.h: Remove the previous _LP64 guards to avoid
	divergence from GMP's longlong.h

	tests: avoid a race in timeout-group.sh
	* tests/misc/timeout-group.sh: The kernel might possibly delay
	signal propagation to timeout.cmd long enough, that it exits
	normally without running the signal handler (as sleep will
	be in the same process group and so get the signal too).
	So avoid this by explicitly checking that the signal handler
	is called, which should always happen under normal circumstances.
	Reported by Stefano Lattarini on linux-2.6.30-2-686 and bash-4.2.36.

	build: avoid --enable-gcc-warnings on GCC <= 4.5
	* configure.ac: Only enable warnings automatically when
	on GCC >= 4.6 (and when building from a git checkout)
	as that was the first GCC version to support fine-grained
	control of warnings, allowing them to be adjusted around
	certain code sections.  gnulib relies on this for certain
	warnings, so avoid auto enabling this option lest we trigger
	build failures on now over two year old compilers.

	arithmetic.

	factor: maintainer builds primes.h, not builder
	With this change, the maintainer builds primes.h and it is part of

	* .gitignore: Remove /src/primes.h.
	* src/factor.c: Include verify.h.
	(W): New constant.  Verify that uintmax_t lacks holes
	and that W is no wider than the integers used to generate primes.h.
	* src/local.mk (EXTRA_DIST): Add src/primes.h.
	(BUILT_SOURCES, CLEANFILES): Remove src/primes.h.
	($(top_srcdir)/src/primes.h): Rename from src/primes.h.
	Do not depend on src/make-prime-list.  Instead, use sub-make to

	(wide_uint): Define to uintmax_t or unsigned __int128 if not #defined.
	(struct prime, binvert, process_prime): Use it instead of uintmax_t.

	in the "total" line.

2012-11-08  Bernhard Voelker  <mail@bernhard-voelker.de>

	df: add --output to select which fields to display
	This supports changing the order of the fields displayed,
	and also allows the simultaneous display of inode and block fields.

	src/df.c (get_dev): Factor out calling get_header to ...
	(main): ... here.  Call print_table only if file_systems_processed.

	src/df.c (Displayable fields): Rename DEV_FIELD to SOURCE_FIELD.
	Rename TYPE_FIELD to FSTYPE_FIELD.  Rename FREE_FIELD to AVAIL_FIELD.
	Rename MNT_FIELD to TARGET_FIELD.

	* src/df.c (display_field_t): Turn loose enum definition of the
	displayable fields into a typedef.  Add the inode fields ITOTAL_FIELD,
	IUSED_FIELD, IAVAIL_FIELD, IPCENT_FIELD.
	(field_data_t): Define structure to hold the display field, the
	caption, the width and the alignment for each field of the above
	type.
	(field_data): Add array the values of field data for each display
	field.
	(headers, alignments, widths): Remove arrays.
	(columns): Add a pointer to the storage for the array of the actual
	output columns, i.e., fields.
	(ncolumns): Add counter for the current output columns.
	(alloc_table_row): Allocate the dynamic ncolumns value of strings.
	(print_table): Loop over ncolumns instead of constant NFIELDS.  Rename
	loop variable 'field' to 'col' to avoid ambiguity with the 'field'
	element in the columns structure.  Adjust the condition for printing
	the last column by comparing with the column number instead of the
	field name (TARGET_FIELD).  Use the width and the alignment stored in
	the columns data.
	(alloc_field): Add new function to allocate a field in the columns
	array.
	(get_field_list): Add new function to fill the array of output columns
	for each mode.
	(get_header): Loop over ncolumns instead of constant NFIELDS.  Rename
	the loop variable 'field' to 'col' to avoid ambiguity with the 'field'
	element in the columns structure.  Remove the code for continuing the
	loop if the current column is the file system type and print_type is not
	active (which is now impossible).  Store the cell in the columns store
	along with the new width.
	(get_dev): Loop over ncolumns instead of the constant NFIELDS.  Rename
	the loop variable 'field' to 'col' to avoid ambiguity with the 'field'
	element in the columns structure; move the definition down to where it
	is used first.  Add cases for the inode fields ITOTAL_FIELD,
	IUSED_FIELD, IAVAIL_FIELD and IPCENT_FIELD.  Store the cell in the
	columns store along with the new width.
	(main): Use new get_field_list function to fill the list of output
	columns.

	* src/df.c (print_table): Instead of fputs()ing directly, apply
	ambsalign on the last field, too.  Use the new MBA_NO_RIGHT_PAD flag
	for this.

	* src/df.c (TOTAL_OPTION): Add new enum value.
	(long_options): Use it for the "total" option instead of 'c'.
	(main): Likewise.

	* src/df.c (get_dev): Remove condition to copy the fstype into the
	FSTYPE_FIELD - based on whether print_type is non-Null.  Since the
	introduction of get_field_list(), there are only fields added to
	the columns array which have to be added.

	* src/df.c (get_dev): Guard the summing up of the values for the
	grand total: only do it if we have to print the total and if the
	current invocation is not for processing it.

	* src/df.c (main): Pass a hyphen "-" for the mount point name
	to get_dev.
	(get_dev): As the mount_point is now always there,
	remove the condition and the else case for the TARGET_FIELD.
	Instead, simply copy the mount_point.
	All cells are now always present.  Therefore, add an assertion
	statement if one was not.  Furthermore, hide the problematic
	characters unconditionally.
	(print_table): Remove the skipping of empty cells.
	* tests/df/total-verify.sh: Accommodate to the new "-" in the
	target field of the summary line.
	* NEWS: Mention the change in behavior.

	* src/df.c (field_type_t): Add new typedef of 3 enums to distinguish
	between block, inode and other fields.
	(field_data_t): Add field_type member of the above new type.
	(field_data): Add default values for the above field_type,
	indicating whether a field contains block values, inode values
	or other, generic values.
	(field_values_t): Add this struct to store the field values, used
	by and factored out from get_dev to be able to define such a struct
	for both the inode and the block values.
	(get_field_values): Add this function to obtain the block values
	and the inode values from the file system usage, used by and
	factored out from get_dev.
	(add_to_grand_total): Add this function to sum the values of the
	current mount point up for the grand total, used by and factored
	out from get_dev.
	(get_dev): Move the definition of the variables fsu, buf, pct and
	cell down to where they are used first to give them a better scope.
	Factor out input_units, output_units, total, available,
	negate_available, available_to_root, used and negate_used into the
	above struct field_values_t.
	Factor out the mapping of the fsu values to the above variables
	into above function get_field_values.
	Factor out the summing up of the grand total values into the
	above function add_to_grand_total.
	Define block_values and inode_values of the new type and call the
	new get_field_values to fill them from the fsu values.
	Call the above function add_to_grand_total for summing up the
	values for the grand total.
	Inside the loop over all fields, define a variable 'v' to point
	to either the block_values or the inode_values, depending on the
	current field's field_type.  Change the code in the cases
	TOTAL_FIELD/ITOTAL_FIELD, USED_FIELD/IUSED_FIELD, AVAIL_FIELD/
	IAVAIL_FIELD and PCENT_FIELD/IPCENT_FIELD to use the field values
	where 'v' is pointing to, i.e., either the block_values or the
	inode_values.

	* src/df.c (main): Remove setting of grand_fsu.fsu_blocks in the
	inode_format case as this is no longer needed and would lead to
	wrong results once when mixed block/inode fields will be used.

	* src/df.c (main): Cleanup the code at the end regarding
	file_systems_processed to make the code clearer.

	* src/df.c (inode_format): Remove variable.
	(main): Remove initialization of the above variable.
	In getopts loop, directly set the header_mode to INODES_MODE
	instead of using the above variable.  Afterwards, remove the
	mapping to INODES_MODE as it is already set.

	* src/df.c (posix_format): Move variable ...
	(main): ... to here.

	* src/df.c (print_table): Enhance the comment about 2-line format
	in cases where the SOURCE_FIELD exceeds 20 chars, as such
	behavior has been removed long ago by commit v8.10-40-g99679ff.

	* src/df.c (Display modes): Add OUTPUT_MODE, remove unused NMODES.
	(display_field_t): Remove unnecessary NFIELDS.
	(field_data_t): Add member 'arg' for the field name in the --output
	argument.  Add member 'used' to remember if a field is already used
	in the columns array.
	(field_data): Add values for the above new members arg and used.
	(all_args_string): Add variable which represents the argument for
	the --output option which includes all fields.
	(OUTPUT_OPTION): Add enum to identify the long --output option.
	(long_options): Add optional-argument --output option.
	(alloc_field): Assert that the field is not already used.
	Mark the field as used.
	(decode_output_arg): Add function to parse the comma-separated
	field list passed to the --output option in order to add the
	appropriate fields to the columns array.
	(get_field_list): Add case for the new OUTPUT_MODE to add all
	available fields to columns in the case the --output option
	has been passed without any values.  Use the comma-separated
	field list form to pass to decode_output_arg to keep the field
	header mapping for the OUTPUT_MODE only on one place.
	(main): Define format string msg_mut_excl to be used in the
	following checks whether the use of --output and the other
	option is mutually exclusive.
	In the getopt_long loop, add a check to the case for the -i option
	to issue an error message when it is used together with --output;
	Likewise for -T and -P.
	Add a new case for OUTPUT_OPTION, together with similar checks as
	above and eventually passing the optarg to decode_output_arg.
	After the getopt_long loop, consider the OUTPUT_MODE case in order
	not to run into -h or -P mode.

	* src/df.c (get_dev): Also xstrdup the dev_name, and free it
	afterwards to silence a valgrind warning about definitely lost
	memory.
	(main): Free the columns store to silence valgrind, guarded by
	the IF_LINT macro.

	* src/df.c (main): Pass "total" as the mount point to get_dev if
	the SOURCE_FIELD is not among the columns to output.
	* tests/df/df-output.sh: Change the test to ensure the content of
	the target field of the grand total line: if the source field is
	present, then the target should be "-", else the target field should
	be "target".
	* NEWS (Changes in behavior): Enhance the exiting NEWS entry.
	* doc/coreutils.texi (df invocation): Document the content of the
	source and target field in the grand total line.

	* src/df.c (main): Add another condition to the need_fs_type
	parameter of read_file_system_list whether the FSTYPE_FIELD is
	used or not.

	* src/df.c (get_header): Indicate the block size used,
	in the "size" header, when using --output without -h.
	* tests/df/df-output.sh: Adjust for, and add an extra test for,
	the new behavior.

2012-10-26  Stefano Lattarini  <stefano.lattarini@gmail.com>

	build: man page generation: degrade gracefully when perl is lacking
	Since commit v8.19-118-g57da212, our 'dist-hook' rule tweaked the
	distributed Makefile.in to make each man page 'man/foo.1' depend
	on the corresponding source 'src/foo.c' rather than the corresponding
	program 'src/foo'.  That was done to accommodate systems without
	perl, which cannot run help2man to regenerate the manpage after
	its corresponding program has been built.

	This seems a right and proper graceful degradation, in that the
	man pages dependencies are still 100% correct in a git checkout,
	while being more lax but "more portable" in a distribution tarball.
	Alas, that is not the case in practice, as it turns out the tweaked
	Makefile makes the building of man pages unreliable and potentially
	incorrect!

	In fact, assume that instead of the correct a dependency:

	    man/ls.1: src/ls

	we have the laxer one:

	    man/ls.1: src/ls.c

	and think of what happens if a user modifies, say, 'src/ls.c', and then
	runs "make -j4" to rebuild everything.  The make process will see that
	it has to rebuild the man page 'man/ls.1' (because its prerequisite
	'src/ls.c' has changed), but won't see that it has to rebuild 'src/ls'
	*before* re-running 'help2man' to generate that man page; so, if
	'man/ls.1' is rebuilt before 'src/ls' (which can happen with concurrent
	make), our user will get either a build error (if 'src/ls' did non
	exist) or, worse, a man page with an up-to-date timestamp but an
	out-of-date content.  And what's even worse in all of this is that
	this problem will be present also for users who have perl installed:
	this is not a "graceful degradation" at all!

	In our situation, the best and simplest way to implement a graceful
	degradation it to keep the correct dependencies for man pages (that
	is, "man/ls.1: src/ls"), and if perl is not present, just generate
	dummy man pages reporting that built-time issue and redirecting the
	user back to either the info documentation or the '--help' output.

	As a consequence of this change, we also stop distributing man pages,
	since they will now be generated unconditionally.

	* Makefile.am (do-not-require-help2man): Remove.
	(dist-hook): Don't depend on it.
	* man/local.mk: Remove an obsolete comment.
	(EXTRA_DIST): Stop distributing generated man pages.
	($(EXTRA_MANS)): This no longer needs to depend on $(all_programs).
	(MAINTAINERCLEANFILES): $(ALL_MANS) Do not list it here, and ...
	(CLEANFILES): ... list it here, instead.
	(.x.1): Instead of warning if perl is missing, but then trying to run
	'help2man' unconditionally, simply run ...
	(run_help2man): ... the command referenced by this new variable, that
	expands to a proper invocation of 'help2man' if perl is present, and
	to an invocation of a shell script generating a dummy manpage if it
	is not.
	(EXTRA_DIST): Distribute that shell script.

	factor: fix integer validation and GMP fallback
	In the recent factor rewrite, the GMP code
	wasn't actually used; just an error was printed
	on integer overflow.  While fixing that it was noticed
	that correct input validation wasn't done in all cases
	when falling back to the GMP code.

	* src/factor.c (print_factors) Fallback to GMP on overflow.
	(strto2uintmax): Scan the string for invalid characters,
	so that case can be detected independently of overflow.
	Return an error when an empty string is passed.
	Also allow leading spaces and '+' in input numbers.

	build: avoid link failure when strerror is replaced
	When building the new make-prime-list program on a system for which
	strerror is defined to rpl_strerror, we'd get a link failure.
	The problem is that we're including <config.h> for some definitions,
	but do not want the rpl_ ones, since this particular program must
	not be linked against gnulib (aka libcoreutils.a).  This did not
	arise on Fedora 17 or 18, but did on Debian wheezy/sid.

	(main): Abort if the 8-delta value ever exceeds 255.

	maint: make-prime-list: do not ignore write failure
	Even though this is just a helper program that is run solely to create
	primes.h, it should not ignore a write failure.  Normally we would
	simply call atexit (close_stdout), but we cannot do that from this
	helper program, since it must be built before the generated header,
	primes.h.  If we were to make the linking of make-prime-list depend
	on libcoreutils.a, that would add all lib/*.o files to the list
	of dependents of $(BUILT_HEADERS).  Then, since there is currently no
	provision to ensure that a file like lib/stdio.h (another built header)
	is built before the first lib/*.o file that also includes <stdio.h>,
	some lib/*.o files would be built before lib/stdio.h and some after.
	The former would provoke link failures due to undefined rpl_* functions.
	* src/make-prime-list.c: Include <errno.h>.
	(fclose): Undef, so that a definition to rpl_fclose does not
	cause a link failure.
	(main): Per the above, in this exceptional case, we check for fclose
	and ferror failure manually, and don't worry about the ferror-only
	failure case in which errno may not be relevant.

	maint: make-prime-list: avoid -Wsuggest-attribute=const warning

	timeout: handle signals more transparently
	This was originally attempted in commit v8.12-117-g5a647a0,
	but reverted before release because of the unreliability
	of disabling core dumps using setrlimit() on Linux kernels.
	This new version instead uses prctl() where available to
	more reliably disable core dumps for the timeout process.

	* m4/jm-macros.m4: Define HAVE_SETRLIMIT and HAVE_PRCTL.
	* src/timeout.c (disable_core_dumps): A new function
	that disables coredumps using prctl or setrlimit if available.
	(main): If the child exited with a signal and we can
	disable core dumps, then raise that signal to the timeout
	process itself, so that callers may also see the signal status.
	Also print a message indicating when the monitored command
	dumped core, as that information is lost in the signal
	propagation through timeout.

	ls: fix coloring of dangling symlinks in default listing mode
	When listing a directory containing dangling symlinks,
	and not outputting a long format listing, and orphaned links
	are set to no coloring in LS_COLORS, then the symlinks
	would get no color rather than reverting to the standard
	symlink color.  The issue was introduced in v8.13-19-g84457c4

	* src/ls.c (print_color_indicator): Use the standard method
	to check if coloring is specified for orphaned symlinks.
	The existing method would consider 'or=00' or 'or=0' as significant
	in LS_COLORS. Even 'or=' was significant as in that case the
	string='or=' and the length=0.  Also apply the same change
	for missing symlinks for consistency.
	(gobble_file): Remove the simulation of linkok, which is only

	seq: 70x faster for non-negative whole numbers and incr==1
	Handle non-negative whole numbers robustly and efficiently when
	the increment is 1 and when no format-changing option is specified.
	On the correctness front, for very large numbers, seq now works fine:

	    $ b=1000000000000000000000000000
	    $ src/seq ${b}09 ${b}11
	    100000000000000000000000000009
	    100000000000000000000000000010
	    100000000000000000000000000011

	while the old one would infloop, printing garbage:

	    $ seq ${b}09 ${b}11 | head -2
	    99999999999999999997315645440
	    99999999999999999997315645440

	The new code is much more efficient, too:
	Old vs new: 55.81s vs 0.82s

	  $ env time --f=%e seq $((10**8)) > /dev/null
	  55.81
	  $ env time --f=%e src/seq $((10**8)) > /dev/null
	  0.82

	factor: NEWS and tests
	* NEWS (Bug fixes): Mention it.
	* tests/misc/factor.pl: Add five of Torbjörn's tests.

2012-09-07  Torbjörn Granlund  <tg@gmplib.org>

	factor: don't ever declare composites to be prime
	The multiple-precision factoring code (with HAVE_GMP) was copied from
	a now-obsolete version of GMP that did not pass proper arguments to
	the mpz_probab_prime_p function.  It makes that code perform no more
	than 3 Miller-Rabin tests only, which is not sufficient.

	A Miller-Rabin test will detect composites with at least a probability
	of 3/4.  For a uniform random composite, the probability will actually
	be much higher.

	Or put another way, of the N-3 possible Miller-Rabin tests for checking
	the composite N, there is no number N for which more than (N-3)/4 of the
	tests will fail to detect the number as a composite.  For most numbers N
	the number of "false witnesses" will be much, much lower.

	Problem numbers are of the form N=pq, p,q prime and (p-1)/(q-1) = s,
	where s is a small integer.  (There are other problem forms too,
	involving 3 or more prime factors.)  When s = 2, we get the 3/4 factor.

	It is easy to find numbers of that form that cause coreutils' factor to
	fail:

	  465658903
	  2242724851
	  6635692801
	  17709149503
	  17754345703
	  20889169003
	  42743470771
	  54890944111
	  72047131003
	  85862644003
	  98275842811
	  114654168091
	  117225546301
	  ...

	There are 9008992 composites of the form with s=2 below 2^64.  With 3
	Miller-Rabin tests, one would expect about 9008992/64 = 140766 to be
	invalidly recognized as primes in that range.

	* src/factor.c (MR_REPS): Define to 25.
	(factor_using_pollard_rho): Use MR_REPS, not 3.
	(print_factors_multi): Likewise.
	* THANKS.in: Remove my name, now that it will be automatically
	included in the generated THANKS file.

	build: default to --enable-gcc-warnings for git tree
	Anyone developing on coreutils can be assumed to have a new enough
	environment, such that enabling gcc warnings by default will be
	useful.  Tarballs still default to no warnings, and the defaults
	can still be overridden with --disable-gcc-warnings.

	* configure.ac (gl_gcc_warnings): Set default based on environment.
	Suggested by Bernhard Voelker.

	* NEWS (Improvement): Mention it.

2012-09-05  Jim Meyering  <meyering@redhat.com>

	rm: be more careful when using a replacement errno value
	* src/remove.c (excise): Tighten the test for when we defer to an
	old errno value: instead of relying solely on an FTS_DNR (unreadable
	directory) failure, also test current and replacement errno values.
	This change would also have solved the problem addressed by commit
	v8.19-106-g57dd067.  For more info, see http://bugs.gnu.org/12339#113

	rm: avoid bogus diagnostic for a slash-decorated symlink-to-dir
	These commands would evoke an invalid diagnostic:
	    $ mkdir d && ln -s d s && env rm -r s/
	    rm: cannot remove 's': Too many levels of symbolic links
	remove.c was stripping trailing slashes from "s/" before passing
	the name to "rm".  But a trailing slash may change the semantics,
	and thus should not be stripped.
	* src/remove.c (rm_fts): Do not strip trailing slashes.
	* tests/rm/v-slash.sh: Adapt to new expected output.
	* gnulib: Update to latest, for an improved fts.c that merely
	normalizes trailing slashes.
	Reported by Paul Eggert in discussion of http://bugs.gnu.org/12339

	tests: depend on the programs we're testing
	* tests/local.mk ($(TEST_LOGS)): Depend on $(PROGRAMS), so that
	tests are rerun when any program is rebuilt.  Technically, we could
	specify precisely which few programs are dependents of each test,
	but that can come later, if deemed worth the trouble and maintenance
	burden.  Also, there is the issue of the primary program(s) being
	tested (i.e., those itemized via print_ver_) versus those that are
	tested incidentally: for example, nearly every test exercises "rm"
	when its clean-up code removes files.

2012-09-05  Stefano Lattarini  <stefano.lattarini@gmail.com>

	maint: fix a spurious syntax-check failure
	* cfg.mk (exclude_file_name_regexp--sc_file_system): Exempt

	* tests/init.cfg (stty_reversible_init_): Quote '$abs_top_srcdir'
	properly.
	(fiemap_capable_): Quote '$abs_srcdir' properly.
	(require_dirent_d_type_): Likewise.

	maint: fix syntax checks 'sc_root_tests'
	* cfg.mk: Don't work by trying to parse the (now gone) file
	'tests/Makefile.am'; rather, use the contents of the make variable,
	$(all_root_tests), introduced few commits ago.
	Fix a few unrelated cosmetic issues while at it.

	maint: avoid a spurious syntax-check error
	* cfg.mk (exclude_file_name_regexp--sc_prohibit_test_backticks): Exempt
	'tests/local.mk' rather than 'tests/Makefile.am'.

2012-09-05  Stefano Lattarini  <stefano.lattarini@gmail.com>

	maint: vc_exe_in_TESTS should actually be a syntax check
	Because it requires the presence of the '.git' directory, that is,
	can be run only for maintainers working from checked-out sources.

	* tests/local.mk (vc_exe_in_TESTS): Rename and move ...
	* cfg.mk (sc_tests_list_consistency): ... here, with minor adjustments.

2012-09-05  Stefano Lattarini  <stefano.lattarini@gmail.com>

	build: remove two now-useless convenience targets
	* src/local.mk (built_programs.list, all_programs.list): These.

	tests: put test-suite.log back in 'tests/'
	* tests/local.mk (TEST_SUITE_LOGS): Define to 'tests/test-suite.log'.

	build: don't use recursive make for tests/ subdirectory
	* Makefile.am (SUBDIRS): Remove 'tests'.
	(include): The '$(top_srcdir)/tests/local.mk' file.
	(check-root): Remove this convenience target, it's no longer needed
	now that the "real" check-root target once in 'tests/Makefile' will
	land in the top-level makefile.
	* configure.ac (AC_CONFIG_FILES): Remove 'tests/Makefile'.
	* tests/Makefile.am: Rename ...
	* tests/local.mk: ... like this, with a lot of adjustments.
	* tests/init.cfg: Move ...
	* init.cfg: ... here.  This is necessary, for a limitation of the
	gnulib-provided 'tests/init.sh', which unconditionally look for
	'init.cfg' in the $(srcdir) directory.
	* tests/*/*.sh: Adjust: expect init.sh to be in '$srcdir/tests',
	not in '$srcdir', and extend $PATH with './src', not with '../src'.
	* tests/Coreutils.pm: Adjust similarly.
	* tests/pr/pr-tests.pl ($pfx): Likewise.

2012-09-05  Stefano Lattarini  <stefano.lattarini@gmail.com>

	maint: list of names of built programs available in the Makefiles
	This is just a preparatory refactoring in view of future changes.

	* configure.ac (AC_SUBST): New 'built_programs'.
	* tests/Makefile.am (AM_TESTS_ENVIRONMENT): Simply define the exported
	variable 'built_programs' to the expansion of the '$(built_programs)'
	AC_SUBST'd make variable.
	(.built-programs): Remove this now-unneeded convenience target.
	(CLEANFILES, check_DATA): Delete, no longer needed.

2012-09-05  Stefano Lattarini  <stefano.lattarini@gmail.com>

	maint: remove anachronistic syntax-check
	* cfg.mk (sc_no_exec_perl_coreutils): This.  Our new testsuite
	layout (perl tests having '.pl' suffix, shell tests having '.sh'
	suffix) makes it basically impossible to run into the issue this
	check guarded against.

	maint: remove duplicated declaration of the 'sc_check-AUTHORS' target
	* cfg.mk: Here.

2012-09-05  Stefano Lattarini  <stefano.lattarini@gmail.com>

	tests: remove the unused 'root-hint' target
	* tests/Makefile.am (root-hint): Here.  The interested user can see
	the reasons why some tests are skipped by looking at the messages
	they display on the console; here's an excerpt:

	    ...
	    PASS: misc/id-groups.sh
	    id-setgid.sh: skipped test: must be run as root
	    SKIP: misc/id-setgid.sh
	    PASS: misc/md5sum.pl
	    ...
	    PASS: df/total-verify.sh
	    2g.sh: skipped test: very expensive: disabled by default
	    SKIP: du/2g.sh
	    ...

	Clear enough, and more specific and precise that a generic "some tests
	might need to be run as root" message.  And if that user is interested
	in making those tests run anyway, he'll just take a look to the README
	files to look for info.  So there's no reason to pollute the stdout
	with another "hint" that is subsumed by those messages, and that might
	go unnoticed anyway.

	Moreover, and possibly more importantly, that hint wasn't being
	displayed anyway, even before this change!  That's because the
	'root-hint' target was listed as prerequisite for the 'check-recursive'
	target, which however was not a dependency of the 'check' target in
	'tests/Makefile.am', because that file contains no $(SUBDIRS)
	definition.

2012-09-05  Stefano Lattarini  <stefano.lattarini@gmail.com>

	tests: use suffix, not exec-bit, to tell which files are tests
	* tests/Makefile.am (vc_exe_in_TESTS): Adjust to look, in the 'tests/'
	subdirectory, for files that have one of the extensions listed in
	$(TEST_EXTENSIONS), rather than for executable files.

	maint: make vc_exe_in_TESTS also work in VPATH builds
	* tests/Makefile.am (vc_exe_in_TESTS): It is easy to adjust this
	recipe to also work in VPATH setups, also thanks to modifications
	done by previous changes.

	maint: remove useless dependency for vc_exe_in_TESTS
	* tests/Makefile.am (vc_exe_in_TESTS): No need to depend on Makefile:
	this target is .PHONY, so it is always run anyway.

	maint: avoid parsing of Makefile.am from vc_exe_in_TESTS
	* tests/Makefile.am (TESTS): Rename ...
	(all_tests): ... like this, so that we'll still be able to know the
	complete list of our tests even if the user overrides TESTS from the
	command line (which he's allowed to do by the test harness API).
	(root_tests): Rename ...
	(all_root_tests): ... like this, for similar reasons.
	(TESTS, root_tests): Redefine their defaults to to $(all_tests) and
	$(all_root_tests) respectively.
	(vc_exe_in_TESTS): It can now safely use $(all_tests) to get the
	complete list of test cases according to the Makefile, instead of
	having to resort to "parsing" of Makefile.am.
	(EXTRA_DIST): Use $(all_tests), not $(TESTS).
	(v_, w_): Delete, no longer needed.

	build: use 'check-local' to extend the 'check' target
	* tests/Makefile.am (check-local): Here, by making this depend
	on 'vc_exe_in_TESTS' ...
	(check): ... rather than making this depend on them.  While the old
	usage worked, it relied on an implementation detail rather than on
	documented behavior.
	* src/local.mk (check-local): Similarly, make this depend on
	'check-README' and 'check-duplicate-no-install' ...
	(check): ... rather than on this.

2012-09-02  Stefano Lattarini  <stefano.lattarini@gmail.com>

	scripts: autotools-install: allow user-specified make program
	* scripts/autotools-install: Honor $MAKE.  This might be useful

	scripts: autotools-install: style and portability fixes

	maint: disable sc_proper_name_utf8_requires_ICONV test
	It would still pass, but would print many diagnostics like this:
	  Can't open src/Makefile.am: No such file or directory.
	* cfg.mk (local-checks-to-skip): Temporarily disable a test.
	This test will need to be adapted to work with a non-recursive
	build set-up, in which there is no Makefile.am alongside each program.
	Reported by Bernhard Voelker.

	maint: accommodate upcoming, expanded list of warnings from gnulib
	* configure.ac: Disable a new gcc warning, -Wsuggest-attribute=format,
	since it triggers on copy.c (which I'm not inclined to adjust) and
	factor.c's use of vfprintf which would appear to require a change
	to stdio.h.

2012-09-01  Stefano Lattarini  <stefano.lattarini@gmail.com>

	maint: fix build_programs definition not to use "make -C src ..."
	* dist-check.mk (built_programs): There's no need to issue recursive
	make calls in 'src/' to define this (in fact, that works no longer
	now that 'src/Makefile.am' is gone).  Simply define this to the sorted
	contents of $(bin_PROGRAMS), with the 'src/' prefix and the $(EXEEXT)
	suffix (if any) removed.  Reported by Jim Meyering.

2012-09-01  Jim Meyering  <meyering@redhat.com>

	build: restore handling of space-tainted build directory name
	* man/local.mk: With commit v8.19-84-g08cf455, man page creation
	would fail when using a build directory name containing e.g.,
	spaces.

	build: make each man/prog.1 depend on src/prog, not src/prog.c
	* man/local.mk: Creating a prog.1 man page requires running
	src/prog --help.
	List the exceptions, e.g., install.1 depends on src/ginstall
	and arch.1 depends on src/uname.

	maint: check-programs-vs-x: avoid a new syntax-check failure
	* cfg.mk (check-programs-vs-x): The new variable,
	$(all-progs-but-lbracket) contains libstdbuf.so, and it does
	not have a corresponding .x file, so exempt it.

	maint: avoid distcheck failure by properly cleaning $(ALL_MANS)
	* man/local.mk (distclean-local): Remove $(ALL_MANS) when doing
	a VPATH build.  If it's not done, generated manpages can be left
	around in the build directory after a "make distclean", causing
	failures in "make distcheck".

2012-09-01  Stefano Lattarini  <stefano.lattarini@gmail.com>

	maint: port manpages generation to VPATH builds
	* man/local.mk (.x.1): Use '$(MKDIR_P)' rather than bare 'mkdir'
	where appropriate.  Reported by Jim Meyering.

2012-09-01  Jim Meyering  <meyering@redhat.com>

	build: fix VPATH issues in C compilation
	* src/local.mk (AM_CPPFLAGS): Add 'src' to the directories that
	are searched for #include'd files.

2012-09-01  Stefano Lattarini  <stefano.lattarini@gmail.com>

	maint: simplify declaration of "libexec" programs
	* configure.ac: No need to use 'gl_ADD_PROG' and an indirection
	variable '$optional_pkglib_progs' to declare the 'libstdbuf.so'
	"libexec" program; the decision to whether compile that program
	is not up to the user, but it only and simply depends on whether
	the 'stdbuf' "bin" program is to be built or not.

	build: $(mandeps): new, to factor out man pages dependencies
	* man/local.mk (mandpep): Rename ...
	(mandeps): ... like this.  Make $(ALL_MANS) depend on its
	content.  List 'src/system.h' in here, instead of making
	$(ALL_MANS) depend on it explicitly.
	(man/*.1): No need to list $(mandep) among the dependencies
	any longer.

	build: enhance man pages cleaning and dependencies
	* man/local.mk: All of the manpages should depend on 'src/system.h',
	and all of them should be cleaned by "make maintainer-clean", that
	is, added to MAINTAINERCLEANFILES.  Make it be so.
	Some minor cosmetic tweakings and reorderings while at it.

	build: simplify: get rid of yet some more indirection variables
	* configure.ac: Adjust and improve few comments.
	(MAN): Rename ...
	(man1_MANS): ... to this.
	Ensure it isn't initialized in all Makefiles (which would lead
	to spurious errors), by calling AM_SUBST_NOTMAKE on it.
	Also call AM_SUBST_NOTMAKE on 'EXTRA_MANS', for consistency.
	* man/local.mk (man1_MANS): Simply define to '@man1_MANS@'.

2012-09-01  Stefano Lattarini  <stefano.lattarini@gmail.com>

	build: rename dist_man1_MANS -> man1_MANS
	And list $(man1_MANS) directly in $(EXTRA_DIST) instead.
	This is similar to what is done for $(EXTRA_MANS), thus
	improving consistency and readability.

	* man/local.mk (dist_man1_MANS): Rename ...
	(man1_MANS): ... like this.
	(EXTRA_DIST): Add its contents.
	* cfg.mk (check-x-vs-1): Fix a botched comment.

2012-09-01  Stefano Lattarini  <stefano.lattarini@gmail.com>

	build: one less unneeded make variable
	* man/local.mk (man_aux): This was used only once, so inline its
	expansion at its sole point of use ...
	(EXTRA_DIST): ... here.

2012-09-01  Stefano Lattarini  <stefano.lattarini@gmail.com>

	build: simplify and make more portable to non-GNU make
	The AC_SUBST'd variable '$(NO_INSTALL_PROGS_DEFAULT)' is only used in
	makefile expressions expanding the list of manual pages that are not
	built by default (but might need to be when a distribution tarball
	is created). Such expressions exploited a feature of make variable
	expansion -- namely, $(VAR:%=dir/%.x) -- that, while seemingly quite
	portable in practice, is not POSIX-conforming, and could break on
	lesser vendor make implementations.  So kill two birds with one stone,
	by getting rid of the $(NO_INSTALL_PROGS_DEFAULT) intermediate variable
	and improving makefile portability in the process.

	While at it, we also clean up some other minor naming inconsistency
	and useless indirection.

	* configure.ac (NO_INSTALL_PROGS_DEFAULT): Don't define or AC_SUBST
	anymore; instead ...
	(EXTRA_MANS): ... define and AC_SUBST these.
	* man/local.mk (extra_man_1): Rename ...
	(EXTRA_MANS): ... like this, explicitly making clear it's AC_SUBST'd.
	(extra_man_x): It's used only once, no need to define it; just inline
	its only expansion where needed.
	(EXTRA_DIST): Adjust.
	(ALL_MANS): New, union of $(EXTRA_MANS) and $(dist_man1_MANS).
	* cfg.mk (check-x-vs-1, sc_option_desc_uppercase): Rely on $(ALL_MANS)
	rather than on $(NO_INSTALL_PROGS_DEFAULT) and $(dist_man1_MANS).

2012-09-01  Stefano Lattarini  <stefano.lattarini@gmail.com>

	build: simplify: get rid of some indirection variables
	The code deciding which coreutils programs to build (depending on
	defaults, system capabilities, and user requests) is overly complex
	and rather confusing.  Let's begin simplifying it by removing some
	non-strictly-necessary indirection variables.

	* configure.ac: Adjust and improve few comments.
	(OPTIONAL_BIN_PROGS, OPTIONAL_PKGLIB_PROGS): Rename ...
	(bin_PROGRAMS, pkglibexec_PROGRAMS): ... like these, respectively.
	Ensure they aren't initialized in all Makefiles (which would lead
	to spurious errors), by calling AM_SUBST_NOTMAKE on them.
	* src/local.mk: Adjust and improve few comments.
	(bin_PROGRAMS, pkglibexec_PROGRAMS): Simply define
	to the corresponding '@substitution@'.

2012-09-01  Stefano Lattarini  <stefano.lattarini@gmail.com>

	maint: update gitignore entries
	* src/.gitignore: Here, adding the '.dirstamp' file generated
	by the C compilation rules.

	maint: fix one stray reference to src/Makefile.am
	* build-aux/gen-lists-of-programs.sh: In heading comments here.

2012-09-01  Stefano Lattarini  <stefano.lattarini@gmail.com>

	maint: fix and simplify maintainer checks
	Some of them can be simplified after the previous changes, some
	of them have been downright broken by them, and need fixing.

	* src/local.mk: Adjust some comments.
	(EXTRA_DIST): Avoid SPACE-TAB sequences.
	(src/dircolors.h, src/fs.h src/fs-is-local.h): Avoid 8-SPACES
	indentation.
	(_sc_check-AUTHORS): Move ...
	* cfg.mk (sc_check-AUTHORS): ... here (superseding the old rule
	with the same name, that was just a recursive invocation to it).
	Adjust the paths of the invoked coreutils programs, to account
	for the fact that this rule now runs in the top-level build dir,
	not in the 'src/' subdir.  Other minor cosmetic adjustments.
	(ALL_RECURSIVE_TARGETS): Remove 'sc_option_desc_uppercase' and
	'sc_man_file_correlation', since they no longer entail any
	recursive make invocation.
	(sc_option_desc_uppercase): Remove dependency from $(all_programs):
	it isn't actually needed.
	(check-programs-vs-x): Likewise.  Also, fix heading comments to
	truly reflect what this check does.
	(all-progs-but-lbracket): Strip the 'src/' prefix from each entry
	in the list of programs; this avoids a spurious failure in the
	'check-programs-vs-x' recipe.
	(.PHONY): No need to list targets 'sc_man_file_correlation' and
	'sc_option_desc_uppercase': they are automatically declared phony
	by 'maint.mk', being recognized as syntax checks.

2012-09-01  Stefano Lattarini  <stefano.lattarini@gmail.com>

	maint: remove unused target 'install-root'
	It was unneeded and broken since the removal of 'su' from GNU
	coreutils, in commit v8.17-16-g928dd73 of 2012-06-06, "su: remove
	program (util-linux is now the best source for it)".

	* Makefile.am (install-root): Remove.
	(ALL_RECURSIVE_TARGETS): Update.

2012-09-01  Stefano Lattarini  <stefano.lattarini@gmail.com>

	maint: improve remake rules for maintainers
	This is a follow up on today's commit v8.19-60-g4f2e62b".

	* Makefile.am ($(top_srcdir)/m4/cu-progs.m4,
	$(srcdir)/src/cu-progs.mk): New, generate these files from the
	'build-aux/gen-lists-of-programs.sh', the same way it's done
	from the bootstrap script.
	* bootstrap.conf (bootstrap_post_import_hook): Add comment about
	the necessity to keep those new rules synced with the commands
	here.  Enhance those commands so to that the generated files are
	set read-only.

2012-09-01  Stefano Lattarini  <stefano.lattarini@gmail.com>

	build: fix generation of manpages for programs not built by default
	* src/local.mk (dist-hook): Don't use this to ensure all the
	programs, even the ones disabled by default or by the user, are
	built (doing so is required to ensure the distributed manpages
	are properly built).  This would build those programs too late
	anyway, causing errors like:

	    $ make dist
	    make  dist-xz am__post_remove_distdir='@:'
	    make[1]: Entering directory `~/src/coreutils'
	      GEN      man/arch.1
	    help2man: can't get '--help' info from man/arch.td/arch
	    make[1]: *** [man/arch.1] Error 127
	    make[1]: Leaving directory `~/src/coreutils'
	    make: *** [dist] Error 2

	Instead, ...
	* man/local.mk (extra_man_x, extra_man_1): define these ...
	($(extra_man_1)): ... and make this depend on $(all_programs).
	(EXTRA_DIST): Adjust.
	Adjust some comments as well.

2012-09-01  Stefano Lattarini  <stefano.lattarini@gmail.com>

	build: don't use recursive make to build the 'src' subdirectory
	* Makefile.am (SUBDIRS): Remove 'src'.  Ensure '.' is listed before
	'tests' and 'gnulib-tests'.
	(dist-hook): Adjust: we must now tweak the top-level Makefile.in
	in $(distdir), not the one in the 'src/' subdir (which is gone).
	(include): The '$(top_srcdir)/src/local.mk' file.
	* build-aux/gen-lists-of-programs.sh: Adjust the generation of the
	automake input fragment.
	* tests/Makefile.am (.built-programs): Adjust.
	* cfg.mk (all_programs): Remove this convenience rule; it's no
	longer needed, now that we can rely directly on the contents of
	$(all_programs).
	(sc_option_desc_uppercase, check-programs-vs-x:): Adjust lists
	of prerequisites accordingly.
	(all-progs-but-lbracket): Simplify definition accordingly.
	* configure.ac ($OPTIONAL_BIN_PROGS): Adjust definition.
	($OPTIONAL_PKGLIB_PROGS): Likewise.
	($NO_INSTALL_PROGS_DEFAULT): Tweak definition, for consistency.
	(AC_CONFIG_FILES): Remove 'src/Makefile'.
	* src/Makefile.am: Rename ...
	* src/local.mk: ... like this, with a lot of adjustments.  In
	addition ...
	(all_programs): ... remove this now-unneeded convenience target.

2012-09-01  Stefano Lattarini  <stefano.lattarini@gmail.com>

	build: refactor how lists of coreutils programs are defined
	This is in preparation of future changes.  Still, this patch
	leaves the build system in a better shape; true, with more
	indirections, but also with less convoluted and brittle hacks.

	Unfortunately, this commit also makes some rebuild rules
	incomplete; that will son be fixed by follow-up patches.

	* build-aux/gen-lists-of-programs.sh: New, generates autoconf
	and automake input fragments that define "lists" of all coreutils
	programs, with further distinctions about how and when these
	programs should be built (by default; if the system is capable
	enough; only if the user asks for them explicitly).  This is
	useful to avoid duplicating the definitions of these lists among
	several files (at least 'configure.ac' 'src/Makefile.am'); such
	duplication had proved a source of inconsistencies and bugs in
	the past.  And the pre-existing way to avoid such duplication,
	as implemented in 'configure.ac' before this patch, was overly
	complex and brittle.
	* Makefile.am (EXTRA_DIST): Distribute the new script.
	* bootstrap.conf (bootstrap_post_import_hook): Run the new script
	to generate 'm4/cu-progs.m4' and 'src/cu-progs.mk'.
	* .gitignore: Ignore those files.
	* configure.ac: Include 'm4/cu-progs.m4', and decidedly simplify
	most of the program lists definition and processing accordingly.
	* src/Makefile.am: Similarly include 'src/cu-progs.mk', containing
	definition of variables $(default__progs), $(no_install__progs)
	and $(build_if_possible__progs).  Accordingly ...
	(no_install__progs, build_if_possible__progs): ... remove.
	(EXTRA_DIST): Adjust definition.
	Adjust a comment.

2012-09-01  Stefano Lattarini  <stefano.lattarini@gmail.com>

	maint: add our 'bootstrap_post_import_hook' function
	This is in preparation of future changes.

	* bootstrap.conf (bootstrap_post_import_hook): New, will be executed
	by bootstrap after gnulib-tool but before the autotools.
	Move creation of dummy ChangeLog into it.

2012-08-31  Eric Blake  <eblake@redhat.com>

	build: work with new glibc when not optimizing
	Starting with glibc 2.15, the system headers refuse to compile
	unconditional use of FORTIFY_SOURCE if optimization is disabled
	but -Werror is in effect.

	* configure.ac (FORTIFY_SOURCE): Make conditional.

2012-08-31  Jim Meyering  <meyering@redhat.com>

	scripts: fix the Signed-off-by:-prohibiting hook to actually work
	* scripts/git-hooks/commit-msg: Fix new test: we're searching a
	multi-line buffer, so add the //m modifier.

2012-08-31  Stefano Lattarini  <stefano.lattarini@gmail.com>

	maint: make required gettext version consistent
	* bootstrap.conf ($buildreq): Require gettext >= 0.18.1, consistently
	with the call to AM_GNU_GETTEXT_VERSION in configure.ac.

2012-08-31  Stefano Lattarini  <stefano.lattarini@gmail.com>

	maint: get rid of obsolete script 'cvsu'
	It was useful only back when coreutils used CVS as its version
	control system.

	* build-aux/cvsu: Delete.
	* Makefile.am (EXTRA_DIST): Remove it.
	* cfg.mk: Remove the two exemptions for this removed file.

2012-08-31  Stefano Lattarini  <stefano.lattarini@gmail.com>

	build: don't use '$<' in non-suffix rules
	* src/Makefile.am (fs-def): Here: it's not portable to some non-GNU
	make implementations.

	maint: more uses of $(ASSORT)
	* src/Makefile.am (fs-kernel-magic, fs-magic): Here, instead of
	inlining its expansion "LC_ALL=C sort".

	maint: remove unused variable in src/Makefile.am
	* src/Makefile.am (editpl): This.

2012-08-31  Stefano Lattarini  <stefano.lattarini@gmail.com>

	build: don't use foo_LDADD if there's no foo program
	For example, instead of factoring out the extra linker flags needed
	by 'cp', 'mv' ind 'install' into a '$(copy_LDADD)' variable, factor
	them out in a '$(copy_ldadd)' variable.

	Partly a minor cleanup, partly a preparation for future changes.

	* src/Makefile.am (copy_LDADD): Rename ...
	(copy_ldadd): ... like this.
	(remove_LDADD): Rename ...
	(remove_ldadd): ... like this.
	All uses adjusted.  Some comments updated.

2012-08-31  Stefano Lattarini  <stefano.lattarini@gmail.com>

	build: some refactorings in cfg.mk
	Partly a minor cleanup, partly a preparation for future changes.

	* Makefile.am (all_programs): Rename ...
	(all-progs-but-lbracket): ... like this, and re-define it to expand
	at make time rather than only at recipe time (i.e., using $(shell ...)
	instead of `...`).
	(check-programs-vs-x): Adjust.

2012-08-31  Stefano Lattarini  <stefano.lattarini@gmail.com>

	build: move definition of 'all_programs' in cfg.mk
	* Makefile.am: Move definition of target 'all_programs' from here ...
	* cfg.mk: ... to here, which is the only file where it is used.

2012-08-31  Jim Meyering  <meyering@redhat.com>

	build: reenable just-moved/broken syntax-check rule
	* cfg.mk (sc_option_desc_uppercase): Now that this rule lives in cfg.mk,
	we must search man/*.1, not "*.1".
	Reported by Bernhard Voelker.

2012-08-31  Stefano Lattarini  <stefano.lattarini@gmail.com>

	maint: fixup: don't try to distribute a now-removed file
	* tests/Makefile.am (EXTRA_DIST): Drop 'check.mk', which has been
	removed (being merged into 'tests/Makefile.am') by recent changes.

2012-08-31  Erik Auerswald  <auerswal@unix-ag.uni-kl.de>

	doc: escape double quotes in autotools-install --help
	* scripts/autotools-install: Fix --help so that we actually print
	the double quotes around "make check", in two places.

2012-08-31  Jim Meyering  <meyering@redhat.com>

	scripts: add autotools-install, for those stuck with outdated tools
	* scripts/autotools-install: New script, so you can always build
	from git-cloned sources, even when they require bleeding edge
	m4, autoconf, automake, etc.

2012-08-31  Bernhard Voelker  <mail@bernhard-voelker.de>

	build: fix syntax-check rules broken by test-added .sh/pl suffixes
	* cfg.mk: We exempt a few test files that would otherwise trigger
	false-positive matches in syntax-check rules.  The recent change
	that added a .sh or .pl suffix to each test script made it so
	some of the exclusion regexps would no longer match.
	Include the required \.sh suffix in each such regexp, too.

2012-08-30  Stefano Lattarini  <stefano.lattarini@gmail.com>

	tests: get rid of the 'shell-or-perl' auxiliary script
	It's now easier and faster to simply run the perl ans shell test
	scripts directly with the appropriate interpreter and options.

	* tests/shell-or-perl: Delete.
	* tests/Makefile.am (EXTRA_DIST): Remove it.
	(SH_LOG_COMPILER): Re-define to invoke the correct shell.
	(PL_LOG_COMPILER): Re-define to invoke the correct perl
	interpreter ...
	(TESTSUITE_PERL_OPTIONS): ... with the correct options.
	(XPL_LOG_COMPILER): Use those options instead of inlining
	their expansion.
	(LOG_COMPILER): Delete, no longer needed.

2012-08-30  Stefano Lattarini  <stefano.lattarini@gmail.com>

	tests: add .sh and .pl suffixes to shell and perl tests, respectively
	Not only this shrinks the size of the generated Makefile (from > 6300
	lines to ~3000), but will allow further simplifications in future
	changes.

	* tests/Makefile.am (TEST_EXTENSIONS): Add '.sh' and '.pl'.
	(PL_LOG_COMPILER, SH_LOG_COMPILER): New, still defined simply to
	$(LOG_COMPILER) for the time being.
	(TESTS, root_tests): Adjust as described.
	* All tests: Rename as described.

2012-08-30  Stefano Lattarini  <stefano.lattarini@gmail.com>

	tests: detect missing perl at configure runtime
	* configure.ac (AM_CONDITIONAL): Set the conditional 'HAVE_PERL' to
	true if the configure-time checks (as run by gl_PERL) have been able
	to find a working perl.
	* tests/no-perl: New script, report a diagnostic about "missing perl"
	and exit with status 77.
	* tests/Makefile.am (EXTRA_DIST): Distribute it.
	(TESTSUITE_PERL): New, define to '$(PERL)' if a perl interpreter has
	been found at configure time (i.e., if the 'HAVE_PERL' automake
	conditional is true), and to '$(srcdir)/no-perl' otherwise.
	(LOG_COMPILER): Use $(TESTSUITE_PERL) instead of $(PERL).
	(XPL_LOG_COMPILER): Likewise.
	* tests/shell-or-perl: Simplify: no need to actually check whether
	perl is working.

	tests: avoid use of '-T' in shebang line to enable perl taint mode
	* tests/rm/fail-eperm: Rename ...
	* tests/rm/fail-eperm.xpl: ... like this
	* tests/Makefile.am (TESTS): Adjust.
	(TEST_EXTENSIONS): New, list '.xpl'.
	(XPL_TEST_LOGS): New, run a perl test in tainted mode.
	* tests/shell-or-perl: Simplify this script: we no longer need to
	parse the shebang line and adjust the flags in the perl invocation
	accordingly.

	build: require Automake >= 1.11.2
	Now that we use AM_TESTS_ENVIRONMENT, we must require
	Automake >= 1.11.2.
	* configure.ac (AM_INIT_AUTOMAKE): Bump version requirement to 1.11.2.
	* bootstrap.conf ($buildreq): Likewise.

2012-08-30  Stefano Lattarini  <stefano.lattarini@gmail.com>

	tests: prefer AM_TESTS_ENVIRONMENT over TESTS_ENVIRONMENT
	The latter should be reserved for user overrides.

	* tests/Makefile.am (TESTS_ENVIRONMENT): Rename ...
	(AM_TESTS_ENVIRONMENT): ... like this.

2012-08-30  Stefano Lattarini  <stefano.lattarini@gmail.com>

	tests: merge tests/check.mk into tests/Makefile.am
	The separation has become unnecessary after all the ancient
	'tests/*/Makefile.am' makefiles have been merged into the
	"more-top-level" one 'tests/Makefile.am'.

	* tests/check.mk: Merge ...
	* tests/Makefile.am: ... in here.  Some comments tweaking while
	at it.

2012-08-30  Stefano Lattarini  <stefano.lattarini@gmail.com>

	build: enable the 'subdir-objects' Automake option globally
	This is not strictly required now (it will be once we make more
	parts of the coreutils build system non-recursive), but enabling
	it early helps to ensure that we don't unwittingly introduce any
	incompatibility or subtle breakage later.

	* configure.ac (AM_INIT_AUTOMAKE): Add  'subdir-objects'.

2012-08-30  Stefano Lattarini  <stefano.lattarini@gmail.com>

	maint: update gitignore entries
	* doc/.gitinore: Here, adding the '.dirstamp' file generated by
	the Texinfo rules.

2012-08-30  Jim Meyering  <meyering@redhat.com>

	build: factor out a little more re list of *.texi files
	We may well want to switch from checking all *.texi to
	checking only version-controlled .texi files, so encapsulate
	this concept in one place.

	* doc/local.mk (doc_srcdir): Delete.  Use this instead:
	(texi_files): Define.  All usages adjusted.

2012-08-30  Stefano Lattarini  <stefano.lattarini@gmail.com>

	maint: adjust syntax check 'sc_option_desc_uppercase'
	* cfg.mk (sc_option_desc_uppercase): Here, by grafting the 'man/'
	prefix to the manpages obtained from $(NO_INSTALL_PROGS_DEFAULT)
	and listed as prerequisites for this rule.

	maint: adjust syntax check 'check-x-vs-1'
	* cfg.mk (check-x-vs-1): Here, by stripping 'man/' prefix from
	$(dist_man1_MANS) entries before comparing them with the list of
	expected programs.

2012-08-30  Stefano Lattarini  <stefano.lattarini@gmail.com>

	maint: move man-related syntax checks in cfg.mk
	This is more natural, now that the top-level Makefile has access to
	all the variables and rules once defined only in 'man/Makefile.am'

	* man/local.mk (all_programs, sc_option_desc_uppercase,
	sc_man_file_correlation check-x-vs-1, check-programs-vs-x): Move
	from here ...
	* cfg.mk: ... to here.  Adjust some comments in the process.

2012-08-30  Stefano Lattarini  <stefano.lattarini@gmail.com>

	build: don't use recursive make to build the 'man' subdirectory
	* Makefile.am: Include 'man/local.mk'.
	(SUBDIRS): Remove 'man'.
	* configure.ac ($MAN): Adjust so that each of its entries has a leading
	'man/' component.
	(AC_CONFIG_FILES): Remove 'man/Makefile'.
	* man/Makefile.am: Rename ...
	* man/local.mk: ... like this.  With further adjustments: each 'foo.1'
	target renamed like 'man/foo.1', each '../src/foo.c' dependency as
	'src/foo.c', and each '$(srcdir)' usage as '$(srcdir)/man'.  Also ...
	(mandep): Adjust, removing the leading '../' component.
	Several whitespace adjustments while at it.
	(ASSORT): Remove, it's already defined in the top-level Makefile.am.
	* cfg.mk (sc_option_desc_uppercase, sc_man_file_correlation): Remove
	the associated recipes, they are now directly available from the
	included 'man/local.mk'.  Actually, the other changes in this commit
	have made these recipes instable and not completely correct, but that
	will be fixed in later changes.

2012-08-30  Stefano Lattarini  <stefano.lattarini@gmail.com>

	build: rework some recipes in man/Makefile.am, for future changes
	This change is merely required to make future changes easier.

	In particular, since we are going to merge the contents of
	'man/Makefile.am' into the top-level Makefile, we need to avoid
	conflicts with the rules and variables in 'dist-check.mk', and
	to prepare for changes in the value of the '$*' variable as used
	in the recipe of the '.x -> .1' suffix rule.

	* man/Makefile.am (t, mapped_name): Delete, inlining their use ...
	(.1.x): ... in the recipe of this suffix rule.  Other adjustments
	to prepare to changes in the value of the '$*' automatic variable.
	While at it, made more resilient about unlikely but possible failure.
	Adjust and reorder few comments.

2012-08-30  Stefano Lattarini  <stefano.lattarini@gmail.com>

	build: provide convenience target 'all_programs' also at top-level
	This will be mostly useful in future changes.

	* Makefile.am (all_programs): New, simply work by delegating to
	the same-named target in the 'src/' subdirectory.
	* cfg.mk (sc_option_desc_uppercase): Take advantage of it.
	(sc_man_file_correlation): Likewise.

2012-08-30  Stefano Lattarini  <stefano.lattarini@gmail.com>

	build: make a rule less dependent on exact source tree layout
	This is mostly a preparatory change in view of future ones.

	* man/Makefile.am (.x.1): Use '$(abs_top_builddir)/src' to access
	the 'src' directory.

2012-08-30  Stefano Lattarini  <stefano.lattarini@gmail.com>

	build: rely on VPATH capabilities in man/Makefile
	* man/Makefile.am: In all the 'foo.1' targets, no need to depend
	explicitly on '$(srcdir)/foo.x': the '.x.1' suffix rule takes care
	of that automatically.

	maint: typofix: s/it's/its/
	* man/Makefile.am: Here.

2012-08-30  Stefano Lattarini  <stefano.lattarini@gmail.com>

	build: rename common_dep -> mandep in man/Makefile
	This is mostly a preparatory refactoring in view of future changes.

	* man/Makefile.am (common_dep): Rename ...
	(mandep): ... like this.
	All usages adjusted.

2012-08-30  Stefano Lattarini  <stefano.lattarini@gmail.com>

	build: fix a stray usage of uninitialized $(ME)
	* man/Makefile.am (sc_option_desc_uppercase): Here.

	build: add an explanatory comment
	* man/Makefile.am (EXTRA_DIST): Describe portability issues of the
	idiom we now use.  Reformat the definition a little while at it.

	maint: simplify definition of $MAN in configure.ac
	* configure.ac: Here, by making less use of 'sed' and 'tr' munging,
	and relying on a smarter and simpler shell loop instead.

	build: don't define $(SUFFIXES) explicitly
	* man/Makefile.am (SUFFIXES): Remove definition: Automake is smart
	enough to extract the list of suffixes from the '.x.1' suffix rule
	automatically.

	build: don't use recursive make to build the 'doc' subdirectory
	* doc/Makefile.am: Rename ...
	* doc/local.mk: ... like this.  With further adjustments ...
	(info_TEXINFOS): Prepend 'doc/' to all '*.texi' files listed in
	here.
	(coreutils_TEXINFOS): Likewise, and rename ...
	(doc_coreutils_TEXINFOS): ... like this.
	(constants.texi): Rename ...
	(doc/constants.texi): ... like this.  Adjust the recipe to avoid
	spurious errors.
	(MAINTAINERCLEANFILES): Adjust, and extend with '+=' rather than
	setting it with '='.
	(ME): Delete.
	(find_upper_case_var): Use '$@', not '$(ME)', in error messages.
	* Makefile.am: Include 'doc/local.mk'.
	(SUBDIRS): Remove 'doc'.
	* configure.ac (AC_CONFIG_FILES): Remove 'doc/Makefile'.

	build: use 'check-local' to extend the 'check' target
	* doc/Makefile.am (check-local): Here, by making this depend
	on 'check-texinfo' ...
	(check): ... rather than this.  While the old usage worked, it
	did so for an implementation detail rather than a documented
	behaviour, so relying on that was riskier a "unclean".

2012-08-30  Stefano Lattarini  <stefano.lattarini@gmail.com>

	build: prefer '$(top_srcdir)/doc' over '$(srcdir)' in doc Makefile
	This is just a preparatory refactoring that will become useful in
	a future change (in which the doc/Makefile.am makefile will be merged

	sort: simpler fix for sort -u data-loss bug, and for a FMR bug
	This also fixes a free-memory-read (FMR) bug: when fillbuf's realloc

	the processing of that just-read longer line includes comparison
	against the saved line in freed memory.

2012-08-17  Jim Meyering  <meyering@redhat.com>

	sort: sort --unique (-u) could cause data loss
	sort -u could omit one or more lines of expected output.
	This bug arose because sort recorded the most recently printed line via
	reference, and if you were unlucky, the storage for that line would be
	reused (overwritten) as additional input was read into memory.  If you
	were doubly unlucky, the new value of the "saved" line would not only
	match the very next line, but if that next line were also the first in
	a series of identical, not-yet-printed lines, then the corrupted "saved"
	line value would result in the omission of all matching lines.

	* src/sort.c (saved_line): New static/global, renamed and moved from...
	(write_unique): ...here.  Old name was "saved", which was too generic
	for its new role as file-scoped global.
	(fillbuf): With --unique, when we're about to read into a buffer that
	overlaps the saved "preceding" line (saved_line), copy the line's .text
	member to a realloc'd-as-needed temporary buffer and adjust the line's
	key-defining members if they're set.
	(overlap): New function.
	* tests/misc/sort: New tests.
	* NEWS (Bug fixes): Mention it.
	* THANKS.in: Update.
	Bug introduced via commit v8.5-89-g9face83.

	df: fix exit code and error messages with --total
	When the combination of the file system options with given files or
	devices does not lead to output, "df --total" would exit successfully
	although it should not.

	Examples:
	  $ df --total --type=xfs /          # when / is not an XFS file system
	  $ df --total --local -t nfs  DIR   # nfs is remote per se ...
	  $ df --total -t qwerty /dev/sdb5   # typo in file system type

	Furthermore, "df --total" would not print the error message "no file
	systems processed" when the file argument does not exist or is otherwise
	not accessible.

	Example:
	  $ df --total __not_exist__

	These 2 bugs are present since --total was added by commit
	v6.12-166-gea2887b.

	* src/df.c (get_dev): Do not set file_systems_processed to true when
	force_fsu is true, i.e. when the row for the "total" line is processed.

	preceding diagnostic.

	df: don't output control characters in a mount point name
	It's awkward to read and problematic for scripts when
	control characters like '\n' are output.

	Note other fields are already handled with mbsalign,
	which converts non printable chars to the replacement char.
	A caveat to note with that, is the replacement char takes
	a place in the field and so possibly truncates the field
	if it was the widest field in the records.

	Note a more general replacement function, that
	handles all printable, or non white space characters,
	would require more sophisticated support for various
	encodings, and the complexity vs benefit was not
	deemed beneficial enough at present.
	Perhaps in future a more general replacement function
	could be shared between the various utilities.

	Note <space> is unaffected in any field,
	which could impact scripts processing the output.
	However any of the number fields at least could have
	spaces considering `LANG=fr_FR df -B\'1`, so it's
	probably best to leave spaces, which also allows
	scripts to handle mount points with spaces without change.

	* src/df.c (hide_problematic_chars): Replace control chars with '?'.

	ls: color each symlink-to-relative-name in / properly
	In order for ls --color to color each symlink, it must form the name
	of each referent and then stat it to see if the link is dangling, to

	ls must concatenate the starting directory name and that relative name.
	When, in addition, the starting directory was "/" or "/some-name",

	id: -Zn/-Zr: avoid an invalid diagnostic
	* src/id.c (main): Using -Z with -r or -n would fail with "id: cannot
	print only names or real IDs in default format", in spite of that "-Z",
	which specifies a non-default format.  Now, it succeeds and ignores
	the -n or -r option.  The error was that the test for default_format
	was not updated when I added the new --context (-Z) option in
	commit v6.9-33-g5320d0f.

	id: don't call getcon unnecessarily
	* src/id.c (main): Invocations like "id" and "id -G" would call getcon
	to determine the current security context even though that result would
	not be used.  Similarly, when POSIXLY_CORRECT is set.  Rearrange
	conditionals and hoist the POSIXLY_CORRECT test so that we call
	getcon only when necessary.

	id,groups: with no user name, print only real and/or effective IDs,
	... i.e., don't use the getpw* functions.

	Before this change, running groups or id with no user name argument
	would include a group name or ID from /etc/passwd.  Thus, under unusual
	circumstances (default group is changed, but has not taken effect for a
	given session), those programs could print a name or ID that is neither
	real nor effective.

	To demonstrate, run this:

	    echo 'for i in 1 2; do id -G; sleep 1.5; done' \
	      |su -s /bin/sh ftp - &
	    sleep 1; perl -pi -e 's/^(ftp:x:\d+):(\d+)/$1:9876/' /etc/passwd

	Those id -G commands printed the following:

	    50
	    50 9876

	With this change, they print this:

	    50
	    50

	Similarly, running those programs set-GID could make them
	print one ID too many.

	* src/group-list.c (print_group_list): When username is NULL, pass
	egid, not getpwuid(ruid)->pw_gid), to xgetgroups, per the API

	tests: convert nearly all `...` expressions to $(...)
	Exempt init.sh because it runs before we're assured to have a
	shell that groks $(...).  Exempt *.mk because "$" would have to
	be doubled, and besides, any `...` expression in a .mk file is
	almost certainly evaluated before init.sh is run.  Finally, also
	exempt the perl-based tests, because perl's `...` cannot be
	converted to $(...).  Do that by running this command:

	git grep -l '`.*`' tests \
	  | grep -Ev 'init\.sh|\.mk$' | xargs grep -Lw perl \
	  | xargs perl -pi -e 's/`(.*?)`/\$($1)/g'

	One minor fix-up change was required after that, due to how
	quoting differs:
	diff --git a/tests/chmod/equals b/tests/chmod/equals
	-    expected_perms=$(eval 'echo \$expected_'$dest)
	+    expected_perms=$(eval 'echo $expected_'$dest)

	Another was to make these required quoting adjustments:
	diff --git a/tests/misc/stty b/tests/misc/stty
	...
	-  rev=$(eval echo "\\\$REV_$opt")
	+  rev=$(eval echo "\$REV_$opt")
	...
	-      rev1=$(eval echo "\\\$REV_$opt1")
	-      rev2=$(eval echo "\\\$REV_$opt2")
	+      rev1=$(eval echo "\$REV_$opt1")
	+      rev2=$(eval echo "\$REV_$opt2")

	Also, transform two files that were needlessly excluded above:
	(both use perl, but are mostly bourne shell)

	  perl -pi -e 's/`(.*?)`/\$($1)/g' \
	    tests/du/long-from-unreadable tests/init.cfg

	Since most users won't be building with GNULIB_POSIXCHECK defined in

	by omitting the framework for a posix check, this patch makes it so
	that the framework is omitted by default, while still giving

	It's been a while since we've used GNULIB_POSIXCHECK; see this email:
	https://lists.gnu.org/archive/html/coreutils/2012-03/msg00126.html
	Some of those failures are because we are intentionally avoiding
	specific gnulib modules (that is, we have chosen not to use things
	like fprintf-posix), but until we work with gnulib to avoid particular
	warnings, wiring up an automatic GNULIB_POSIXCHECK to happen during

	du: fix -x: don't ignore non-directory arguments
	Surprise!  "du -x non-DIR" would print nothing.
	Note that the problem arises only when processing a non-directory
	specified on the command line.  Not surprisingly, "du -x" still
	works as expected for any directory argument.

	When performing its same-file-system check, du may skip an entry
	only if it is at fts_level 1 or greater.  Command-line arguments
	are at fts_level == 0 (FTS_ROOTLEVEL).

	* src/du.c (process_file): Don't use the top-level FTS->fts_dev
	when testing for --one-file-system (-x).  It happens to be valid

	maint: use an optimal-for-coreutils xz compression setting
	* cfg.mk: Set XZ_OPT = -8e (determined empirically).
	This sacrifices 8 KiB of compressed tarball size for a 32-MiB
	decrease in the memory required during decompression.  I.e.,
	using -9e would shave off only 8 KiB from the tar.xz file, yet
	would force every decompression process to use 32 MiB more memory.

	Improved-by: Bernhard Voelker

	ls: cache ACL- and CAP-querying syscall failures
	Like the optimization to avoid always-failing getfilecon calls,
	this change avoids always-failing queries for whether a file has
	a nontrivial ACL and for whether a file has certain "capabilities".
	When such a query fails for one file (indicating no support), we know it
	will always fail that way for the affected device.  With this change, we
	have thus eliminated nearly all failing-unsupported getxattr syscalls.
	* src/ls.c (has_capability) [!HAVE_CAP]: Set errno to ENOTSUP.
	(errno_unsupported): Expand the list of E* errno values to match
	that of lib/acl-internal.h's ACL_NOT_WELL_SUPPORTED macro.
	(file_has_acl_cache, has_capability_cache): New functions.
	(gobble_file): Use them in place of non-caching ones.
	* NEWS (Improvements): Mention it.
	Suggested by Sven Breuner in
	http://thread.gmane.org/gmane.comp.gnu.coreutils.general/2187
	While eliminating most getfilecon calls saved about 33%,
	eliminating these other calls can save almost all of the
	remaining ~67% cost, on some remote file systems.

	ls: optimize for when getfilecon would often fail (~33% perf. gain)
	On systems or file systems without SELinux support, all getfilecon
	and lgetfilecon calls would fail due to lack of support.  We can non-
	invasively cache such failure (on most recently accessed device) and
	avoid the vast majority of the failing underlying getxattr syscalls.
	* src/ls.c (errno_unsupported): New function.
	(selinux_challenged_device): New file-scoped global.
	(getfilecon_cache, lgetfilecon_cache): New error-caching wrapper
	functions.
	(gobble_file): Use the caching wrappers, for when many *getfilecon
	calls would fail with ENOTSUP or EOPNOTSUPP.

	tests: more automated quote adjustment
	Relax initial regexp to match more instances, but add a
	filter to avoid some invalid conversions.  Run this:

	git grep -l "\`[^']*'" tests | xargs perl -pi -e '$q=q"'\''";' \
	  -e '$q="$q\\$q$q"; /(= ?\`|\`expr|\`echo|\Q$q\E)/ and next;' \
	  -e ' s/\`([^'\''"]*?'\'')/'\''$1/g'
	The last disjunct in the above (...) filter is to exempt
	any line that contains this string: '\''
	With quoting like that, converting a ` to ' is likely to cause trouble,
	so we'll handle those manually.  Here are three examples where
	the exemption is required:

	  *': `link-to-dir/'\'': hard link not allowed for directory'*) ;;

2012-01-03  Jim Meyering  <meyering@redhat.com>

	df: work around long-named /dev/disk/by-uuid/... symlinks
	On systems with recent kernel/tools, a symlink from /etc/mtab to
	/proc/mounts, and a by-UUID mount (i.e., soon, nearly everyone),
	you will see something like the following when running "df -hT":
	(this has been truncated to fit in a width-limited ChangeLog file)

	Filesystem                                             Type      Siz...
	rootfs                                                 rootfs     11G
	udev                                                   devtmpfs  3.8G
	tmpfs                                                  tmpfs     774M
	/dev/disk/by-uuid/828fc648-9f30-43d8-a0b1-f7096a2edb66 ext4       11G
	tmpfs                                                  tmpfs     1.6G
	/dev/sda2                                              ext3      494M
	/dev/sda5                                              ext4       12G
	/dev/sda6                                              ext4      9.9G

	Contrast that with what we're used to seeing (modulo the
	two entries mounted on "/", which is a separate problem):

	Filesystem     Type      Size  Used Avail Use% Mounted on
	rootfs         rootfs     11G  1.9G  8.0G  19% /
	udev           devtmpfs  3.8G     0  3.8G   0% /dev
	tmpfs          tmpfs     774M  376K  774M   1% /run
	/dev/sda3      ext4       11G  1.9G  8.0G  19% /
	tmpfs          tmpfs     1.6G  8.0K  1.6G   1% /run/shm
	/dev/sda2      ext3      494M   78M  392M  17% /boot
	/dev/sda5      ext4       12G  7.6G  3.7G  68% /usr
	/dev/sda6      ext4      9.9G  6.6G  2.8G  71% /var

	When that long /dev/disk/by-uuid/... name is merely a symlink
	to a much shorter (and often more useful) device name like
	"/dev/sda3", and when it's part of a listing of all file systems,
	I would much prefer to see only the latter.  Similarly, when using
	an encrypted root file system, you would see a name like
	/dev/mapper/luks-828fc648-9f30-43d8-a0b1-f7196a2edb66 pointing
	to say, /dev/dm-0, I prefer the shorter name.

	I.e., if I explicitly run
	"df -hT /dev/disk/by-uuid/828fc648-9f30-43d8-a0b1-f7096a2edb66",
	then, it's fine -- and expected -- to print to the long name.
	It was explicitly given.  However, with no non-option argument,
	df should print the shorter name.  Note that performing this
	translation at a lower level (via a change to gnulib's mountlist.c)
	would make it impossible to distinguish those two cases.

	* src/df.c: Include "canonicalize.h".
	(get_dev): Add a parameter, telling when we're in process-all-
	mount-points mode; update all callers.  When true, resolve
	UUID-suffixed symlinks.

	build: simplify warnings based on last gnulib update
	We no longer need to exclude this warning.

	* configure.ac (WARN_CFLAGS): Gnulib dropped
	-Wunsuffixed-float-constants, as non-portable.

	build: update gnulib for syntax-check improvement
	Commit 5b3e538 proved useful enough to migrate to gnulib after
	enhancing it to be more generic, which in turn pointed out that
	commit a2c811db missed an offender.

	* gnulib: Update to latest.
	* cfg.mk (sc_prohibit_reversed_compare_failure): Delete, now that
	gnulib provides it.
	* tests/ls/dangle: Fix last offender.

2011-11-28  Jim Meyering  <meyering@redhat.com>

	build: enable -Wsuggest-attribute=pure|const in lib/,...
	but not in gnulib-tests/.
	* configure.ac (GNULIB_WARN_CFLAGS): Do not exclude
	-Wsuggest-attribute=pure|const, thus enabling these two warning
	options in lib/, since gnulib now toes the line.
	Continue to disable them in gnulib-tests/, since some programs
	there trigger these suggestions and are not worth fixing.

	build: update gnulib for const+pure attributes

2011-11-27  Jim Meyering  <meyering@redhat.com>

	tests: add a syntax check for last week's global change
	Last week I made a global change, commit a2c811db, `tests: use
	"compare exp out", not "compare out exp"', but forgot to add a
	corresponding syntax check rule.  Without that, it is far too
	easy to add a new test or to merge in an old one that would
	be non-conforming.  Obviously this is only a heuristic, since
	it relies on the expected-output file to have a name that starts
	with "exp".
	* cfg.mk (sc_prohibit_reversed_compare_failure): Prohibit use of
	compare with reversed arguments.

	maint: update comment gcc-4.6.2 still botches -Wsuggest-attribute=pure
	* configure.ac: Update the comment on which gcc versions still must
	not use -Wsuggest-attribute=pure option: still required on post-
	Fedora 16 rawhide's 4.6.2 20111027.

2011-11-24  Jim Meyering  <meyering@redhat.com>

	maint: bootstrap: run autopoint and libtoolize *before* gnulib-tool
	* bootstrap (AUTOPOINT, AUTORECONF): Factor out definitions.
	Run autopoint and libtoolize *before* gnulib-tool.
	After it, run an abbreviated autoreconf, rather than a loop around
	all tools.
	* bootstrap.conf (gnulib_tool_option_extras): Add both --symlink
	and --makefile-name=gnulib.mk.  Remove stray use of $bt.
	* lib/Makefile.am: Initialize all of the following so that
	generated code in gnulib.mk may use += to append to those variables:
	AM_CFLAGS, AM_CPPFLAGS, BUILT_SOURCES, CLEANFILES, EXTRA_DIST,
	MAINTAINERCLEANFILES, MOSTLYCLEANDIRS, MOSTLYCLEANFILES, SUFFIXES,
	noinst_LIBRARIES.

	maint: bootstrap: remove some now-unneeded code
	This bootstrap script arose back when gnulib-tool was young.
	Since then, it has seen improvements that render much of this
	script unnecessary.  In particular, it can now make symlinks
	to the files it uses.  Also, I no longer see as much value in
	marking files as read-only via comments.
	* bootstrap (slirp, bt_mark_as_generated): Remove.

	maint: use gnulib's gettext-h, not the gettext module
	* bootstrap.conf (gnulib_modules): Use gnulib's gettext-h, not the
	gettext module.  Not only is gettext-h far smaller (it has far fewer
	dependencies than the gnulib module), but it does not suffer from
	the problem with the gettext module whereby it adds a -I.../intl
	option to compilation flags.  That can provoke warnings, since we
	don't have such a directory.  We used to work around that via a
	hack in bootstrap, but that was ugly and inefficient.

	maint: append many lib/ and m4/ names to .gitignore

	build: update gnulib submodule to latest for fixed stdalign test

2011-11-23  Jim Meyering  <meyering@redhat.com>

	occasionally trigger this.

	build: update gnulib and tests/init.sh
	* gnulib: Update.
	* tests/init.sh: Update from gnulib.

	build: --enable-gcc-warnings: disable some new warnings
	* configure.ac: Disable some new warning options pulled in via

	-Wunsuffixed-float-constants, -Wdouble-promotion.

	* Makefile.am (check-git-hook-script-sync): New rule -- not used

	ls: plug a per-argument leak
	Using ls -l on an SELinux-enabled system would leak one SELinux

	(clear_files): ...here.  Use it.
	(extract_dirs_from_files): Call free_ent (f), rather than simply

	tests: avoid signal issues in timeout-group
	These issues were seen on an OpenSuse 10.3 system
	(kernel 2.6.22.5 x86_64, glibc 2.6.1-18, bash updated to 4.2),
	and also on a 64 bit SLES system with a 2.6.16 kernel.
	Both systems had 2 CPUs.

	There were two issues seen.  1. Occasionally the
	timeout.cmd shell script would block SIGINT until
	the sleep command exited.  2. Much less frequently the
	signal handler in the timeout command itself was ignored,
	causing SIGALRM to kill the process.

	* tests/misc/timeout-group: Detect the above two cases,
	and skip rather than fail.  Note only issue 2. causes
	a failure unless skipped, but we skip for case 1. also,
	for diagnostic purposes.

2011-11-03  Pádraig Brady  <P@draigBrady.com>

	tests: fix a race in timeout-group
	This could cause a false failure, or even

	* tests/misc/timeout-group: Increase the timeouts
	passed to the timeout command, so that they're
	effectively not used.  Instead the command termination
	is triggered by the kill commands when everything
	is in the correct state.

	Reported by Bernhard Voelker.

	build: adapt to gnulib's recent openat/fchownat separation
	* bootstrap.conf (gnulib_modules): Add fchownat, now that gnulib
	has moved it into its own module.
	* gnulib: Update to latest.

	build: update gnulib for GNUmakefile fix

	maint: avoid new "make syntax-check" failure due to stdalign definition
	* gl/modules/randread (Depends-on): Add stdalign.
	* gl/lib/randread.c: Include <stdalign.h>, so we can ...
	[!_STRING_ARCH_unaligned]: remove definition of stdalign.

	tests: update gnulib to latest to avoid FP DST-related test failure
	Otherwise, "make check" would fail after e.g., a CEST-to-CST
	daylight savings transition.

	tests: don't make tail's pipe-f2 test take the full 10 seconds
	* tests/tail-2/pipe-f2: Don't always wait 10 seconds.
	Before, this test would always wait 10 seconds.
	Now, it stops early when it detects that tail -f has written output.
	BTW, the race condition that prompted changing the timeout from 1 second
	to 10 was that tail -f could be killed by the timeout before producing
	any output.

	date: reinstate the --iso-8601 (-I) option
	We deprecated and undocumented the --iso-8601 (-I) option mostly

	build: do not remove definition of ENODATA, after all
	* src/system.h (ENODATA): Restore definition.
	gnulib defines it only on native Windows systems, so removing our

	like FreeBSD.  Reported by Bruno Haible in
	http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/28739/focus=28795

	rm: update gnulib to get an fts fix for Cygwin+NWFS/NcFsd file systems
	* NEWS (Bug fixes): Mention it.
	As far as we know, this fix affects only Cygwin with NWFS or NcFsd
	file systems.  See these:
	http://git.sv.gnu.org/cgit/gnulib.git/commit/?id=71f13422f3e634

	http://cygwin.com/ml/cygwin/2011-10/msg00365.html
	* src/system.h (ENODATA): Remove fall-back definition, now that
	gnulib provides one.  Caught by the sc_prohibit_always-defined_macros
	syntax-check rule.
	Also remove now-irrelevant "Don't use bcopy..." comment.

2011-10-23  Jim Meyering  <meyering@redhat.com>

	maint: add git hook scripts
	We find it worthwhile to use consistent commit summary prefixes.
	To that end, the commit-msg script requires that all commits I make
	start with "$P: " (where $P is one of ~100 programs in coreutils)
	or one of a few other words, like gnulib tests maint doc build.
	It allows more than one word, so e.g., "cat tail head: " would also
	be accepted.  Pádraig Brady wrote the initial version, with its
	72-column and blank-if-present second line checks.
	The pre-commit script is the same as the git-supplied sample script,
	modulo a bug fix and the "exec 1>&2" redirection.
	* scripts/git-hooks/commit-msg: New file.
	* scripts/git-hooks/pre-commit: New file.
	* scripts/git-hooks/applypatch-msg: New file.  Verbatim from .sample.
	* cfg.mk: Exempt two of the new scripts from the no-leading-TABs check,
	since they're nearly verbatim from git, and we want to stay in sync.
	Exempt the commit-msg script from the no-"fail=0" check.

	tail: with -f, use nanosleep (not inotify) on a GPFS file system
	Because tail's fremote function did not designate GPFS as
	a remote file system type, tail -f would mistakenly attempt
	to use inotify, which cannot work with a remote file system.
	* src/tail.c (fremote): List GPFS as a remote file system type.
	* NEWS (Bug fixes): Mention it.
	Reported in http://bugs.debian.org/646022.

	build: include man-pages for non-default progs
	At the moment, things like man/arch.1 are not included in the tarball.
	This makes perl a requirement if you want to build/install the arch

2011-10-19  Jim Meyering  <meyering@redhat.com>

	maint: tac: prefer "failed to" diagnostic over "cannot"
	* src/tac.c: Change wording in diagnostic: "failed to open" seems
	clearer than "cannot open".

	tac: do not let failed allocation cause immediate exit
	* src/tac.c (temp_stream): Don't exit immediately upon failed heap
	allocation, here.  That would inhibit processing of any additional

	tac: use only one temporary file, with multiple nonseekable inputs
	* src/tac.c (temp_stream): New function, factored out of...
	(copy_to_temp): ...here.
	(tac_nonseekable): Don't free or fclose, now that we reuse the file.
	Suggested by Ambrose Feinstein.
	* THANKS.in: Update.

2011-10-18  Paul Eggert  <eggert@cs.ucla.edu>

	maint: make tac.c slightly cleaner
	* src/tac.c (copy_to_temp): Now that the template string tacXXXXXX

	Also, using three unconditional assignments seems slightly clearer.

2011-10-17  Jim Meyering  <meyering@redhat.com>

	tac: don't leak a file descriptor for each non-seekable input

	rm: do not resort to stat'ing very long names even on deficient systems
	This change affects only systems that have neither *at function support
	nor the /proc/self/fd support required to emulate those *at functions.
	* src/remove.c (write_protected_non_symlink): Call faccessat
	unconditionally.  Thus we no longer need euidaccess_stat, which was

	* NEWS: Mention the bug fix

2011-10-01  Pádraig Brady  <P@draigBrady.com>

	ls: fix output of dangling symlinks colored as target
	This is related to commit b7f2b51c, 2010-01-01,
	"ls: fix color of broken symlinks colored as target"
	which didn't handle the --dereference case.
	The simplest way to reproduce the resultant
	erroneous "argetm" is as follows:

	 $ ln -s /no-such dangle
	 $ env LS_COLORS=ln=target ls --dereference --color
	 ls: cannot access dangle: No such file or directory
	 argetmdangle

	This is also an issue with the `tree` utility,
	reported here: http://bugs.debian.org/586765

	* src/ls.c (print_color_indicator): Move the handling
	of 'ln=target' in $LS_COLORS (color_symlink_as_referent == true)
	to a higher scope, to handle all cases where type == C_LINK.
	* tests/misc/ls-misc: Add a test case for the specific issue,
	and 2 further test cases to verify other code paths in this area.

	Reported by Jason Glassey.

2011-09-30  Jim Meyering  <meyering@redhat.com>

	ls: avoid reading beyond end of color indicator
	At first this looked like a buffer overrun, since there was no test
	to ensure that the buffer length was 6.  However, since the LS_COLORS
	string is NUL-terminated and since settings within it are separated by
	":" there was neither the risk of reading beyond end of buffer nor risk
	of a false-positive match.
	* src/ls.c (print_color_indicator): Use color_symlink_as_referent
	rather than manually comparing against "target" again.
	* src/system.h (STRNCMP_LIT): Correct description in comment.

	tests: update gnulib to latest, to fix test link failure

2011-09-27  Jim Meyering  <meyering@redhat.com>

	sort: avoid a NaN-induced infloop
	These commands would fail to terminate:
	    yes -- -nan | head -156903 | sort -g > /dev/null
	    echo nan > F; sort -m -g F F
	That can happen with any strtold implementation that includes
	uninitialized data in its return value.  The problem arises in the
	mergefps function when bubble-sorting the two or more lines, each
	from one of the input streams being merged: compare(a,b) returns 64,
	yet compare(b,a) also returns a positive value.  With a broken
	comparison function like that, the bubble sort never terminates.
	Why do the long-double bit strings corresponding to two identical
	"nan" strings not compare equal?  Because some parts of the result
	are uninitialized and thus depend on the state of the stack.
	For more details, see http://bugs.gnu.org/9612.
	* src/sort.c (nan_compare): New function.
	(general_numcompare): Use it rather than bare memcmp.
	Reported by Aaron Denney in http://bugs.debian.org/642557.

	timeout: handle implicitly created threads
	On some systems like glibc on GNU/kFreeBSD, a thread is

	* src/timeout.c (send_sig): Change the scheme used to

	pathchk: port to hosts where mbstate_t is replaced
	This problem was discovered when trying to build git coreutils on
	Solaris 8 sparcv9 with Sun C 5.8: the 3rd argument to mbrlen was
	of type int * (a pointer to the gnulib replacement mbstate_t) but
	the system mbrlen wants the system mbstate_t *.
	* bootstrap.conf (gnulib_modules): Add mbrlen.
	* src/pathchk.c (mbrlen, mbstate_t) [!(HAVE_MBRLEN && HAVE_MBSTATE_T)]:
	Remove macros, which are wrong now that gnulib supplies
	replacements for mbstate_t and mbrlen.

	That mapping is required in order to preserve src hard links in the
	destination tree, so when using cp with --update and --preserve=links
	(perhaps via -p or -a), cp could fail to preserve one hard link
	per inode when at least one of the hard-linked names already exists

	timeout: treat seconds counts like 'sleep' does
	Treat fractions as a request to round up to the next representable

	do what the user wants.
	* src/timeout.c: Include c-strtod.h and xstrtod.h, not xstrtol.h.
	(apply_time_suffix): Change it to the way sleep.c's time_suffix
	does things.  Maybe this function (identical in both programs,

	This change implements a more correct and idiomatic use of the

	Using a .diff is much more maintainable.  Otherwise, changes in

2011-06-14  Jim Meyering  <meyering@redhat.com>

	tests: accommodate HP-UX and ksh-derived shells
	Running "make check" normally prints a diagnostic to the outermost
	stderr (usually a tty) to explain why a test is skipped.  It did this
	by redirecting FD 9 to stderr (via "exec 9>&2") before invoking the
	shell script.  Shell scripts write skip-explanation to FD 9 via
	init.sh's skip_ function.  However, with ksh and HP-UX's /bin/sh,
	the effects of "exec 9>&2" are canceled upon fork-and-exec, so we
	would get a "Bad file number" diagnostic and no skip explanation on
	those systems.
	* tests/check.mk (TESTS_ENVIRONMENT): Redirect more portably, via
	"$(SHELL) 9>&2", rather than the prior "exec 9>&2; $(SHELL) ..."
	Actually, we use "shell_or_perl_ 9>&2", to make this effective
	also for the perl-based tests.
	* tests/init.sh (stderr_fileno_): Update the advice in comments.
	See http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/22488
	for lots of discussion.  Stefano Lattarini suggested the solution

	start-relative offset, e.g., "mkfifo f; tail -f -c +3 f", but even
	then, the invalid READ_POS value does not influence how tail works.
	It is stored in the File_spec.size member, but that member is not
	used at all in tail_forever_inotify, and in tail_forever, it is
	used only when the File_spec refers to a regular file.

	http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33498, I now think
	it is worthwhile.  The lesser of two evils.
	Thanks to Daniel Veillard for showing me the gcc bug report.

	maint: accommodate gcc's -Wstrict-overflow option
	* src/factor.c (factor_using_pollard_rho): Change type of "i"
	to unsigned to avoid warning from gcc's -Wstrict-overflow.
	* src/expr.c: Use an unsigned intermediate.
	* src/dircolors.c (main): Reorder operations to avoid the risk of
	pointer overflow.
	* src/tr.c (squeeze_filter): Change NOT_A_CHAR from an anonymous
	"enum" to an "int", to avoid this warning:
	tr.c:1624:10: error: assuming signed overflow does not occur when
	  simplifying conditional to constant [-Werror=strict-overflow]
	* src/pr.c (main): Make index "i" unsigned.

	maint: env.c: remove unnecessary use of strchr
	* src/env.c (main): Remove excess (and confusing to static analyzers)
	use of strchr.

	shred: placate coverity and fix a comment
	* src/shred.c (incname): Add an assertion to tell static analyzers
	that we know this particular use of strchr never returns NULL.

	* src/touch.c (main): Avoid even the hint of possibility that

	the potential, but it appears not to be possible, since posixtime
	rejects any time for which the subsequent localtime would return NULL.

	* tests/misc/tac-continue: Fix typo in usually-skipped test:
	s/mkfifo_or_skip/mkfifo_or_skip_/ (i.e., append "_").
	This test is usually skipped, because I'm probably the only
	one to set the FULL_PARTITION_TMPDIR envvar, and recently the
	one I'd been using ceased to exist, so this test was skipped
	even for me.  Good argument for making this a root-only test

	ls: allow stat-free use of --color
	Even on a system with d_type support, the default use of --color
	makes ls stat every file in order to be able to honor settings like
	EXEC, STICKY, ORPHAN, SETUID, etc., because those settings require
	information that is not provided by dirent.d_type.  However, if
	for a potentially large performance gain, you are willing to disable
	those settings, you can now make ls --color give type-related coloring
	and perform no stat calls at all (other than the unavoidable call-per-
	command-line argument).  Before this change, even with all of those
	attributes disabled, ls --color would still stat every directory.
	Now, we're down to the minimum of one stat call per command-line arg.
	* src/ls.c (gobble_file): With --color, don't stat a
	non-command-line-specified directory when no directory-coloring
	attribute is enabled.

	tests: avoid spurious parallel failure due to temporary disk full
	Running the new fiemap-empty test uses 600MB of disk space via
	fallocate, and in so doing caused failure in unrelated tests that
	were running in parallel on a small file system.  Rather than
	simply running fallocate (which allocates the space, inducing
	disk full when it fails), skip the test if there is less than
	800MB of free space, as computed via stat and awk.
	* tests/init.cfg (require_file_system_bytes_free_): New function.

2011-04-02  Jim Meyering  <meyering@redhat.com>

	cp: always detect copy-into-self: avoid infloop w/large PATH_MAX
	When running the erroneous command, cp -rl A D D, and depending on the
	structure of directories A and D and the file system type (because that
	changes order of dir. entry traversal), cp would sometimes fail to
	detect that D was being copied into D, and would create D/D/D/D/D/...
	until it hit PATH_MAX or exhausted some resource.
	I noticed this via the occasional failure of the cp/into-self test
	when run using a ZFS file system.  It is occasional because the bug
	is dependent on the order in which directory entries are traversed,
	and that is apparently indeterminate with ZFS.
	Technically, with the current recursive implementation, there is no
	risk of an infinite loop, due to stack limitations, but with an
	eventual fts-based implementation, it might have iterated until
	disk space or inodes are exhausted.
	* src/copy.c (copy_dir): Avoid copy-into-self interminable loop on
	systems with large PATH_MAX.  On other systems, diagnose the copy-into-
	self error consistently.  Handle the parameter,
	first_dir_created_per_command_line_arg, correctly when there are two
	or more sub-directories.

	so that the source and dest have the same allocation.  This will

	copy: link rather than copy symlinks, when --link used
	This bug was introduced in commit ca9e212c, 2009-09-24,
	"cp, mv: use linkat to guarantee semantics", which
	inadvertently disabled the creation of hardlinks to symlinks.
	However rather than implementing the intention of that commit
	and relying on gnulib linkat emulation, we'll revert to the
	previous emulation as that maintains ownership and timestamps.

	* src/copy.c (copy_internal): Use our existing hardlink to
	symlink emulation when link() might dereference the symlink.
	Also ensure that we copy the timestamps of the original symlink
	when we use the emulation.

	du: don't infloop for --files0-from=DIR
	* src/du.c (main): Fail on AI_ERR_READ error, rather than merely
	diagnosing and continuing.  Based on a patch by Stefan Vargyas.
	Also move the handling of AI_ERR_EOF into the case stmt.
	Do not report ferror/fclose(stdin) failure when we've
	already diagnosed e.g., failure to read the DIR, above.
	Bug introduced by 2008-11-24 commit 031e2fb5, "du: read and
	process --files0-from= input a name at a time,".
	* src/wc.c: Handle read failure as with du: do not exit
	immediately, but rather go on to print any total and to clean-up.
	As above, move the handling of AI_ERR_EOF into the case stmt.
	* tests/du/files0-from-dir: New file, to test both du and wc.
	* tests/Makefile.am (TESTS): Add it.
	* NEWS (Bug fixes): Mention it.

	wc: avoid NULL dereference on out-of-memory error
	* src/wc.c (main): Diagnose failed argv_iter_init_* failure,
	rather than falling through and dereferencing NULL.
	Bug introduced by 2008-11-25 commit c2e56e0d,
	"wc: read and process --files0-from= input a name at a time,".

	tests: without filefrag, only skip part of sparse-fiemap
	* tests/cp/sparse-fiemap: Move the PERL check to the top,
	since we don't test anything without it.  In the loop,
	don't use skip_test_ as it exits the test completely.

2011-02-18  Jim Meyering  <meyering@redhat.com>

	stdbuf: avoid even the appearance of a possible use-after-free
	There was an execution path by which "libstdbuf" could be used after
	being freed, but that would happen only if there were no libstdbuf.so
	alongside the stdbuf program and there had been an installation error
	leading to absence of the file, PKGLIBDIR/libstdbuf.so.
	* src/stdbuf.c (set_LD_PRELOAD): Rearrange loop to make it perfectly
	clear that there is no possibility of use-after-free.
	Steve Grubb reported this possible use-after-free of "libstdbuf".

2011-02-18  Gilles Espinasse  <g.esp@free.fr>

	tests: correct racy sparse-to-pipe test

	before comparing the results.

2011-02-15  Paul Eggert  <eggert@cs.ucla.edu>

	uptime: omit unnecessary #if
	* src/uptime.c (print_uptime): Omit unnecessary "#if defined
	HAVE_GETLOADAVG || defined C_GETLOADAVG".  This #if is always
	true, and removing it will help us simplify the gnulib getloadavg
	module.

2011-02-15  Pádraig Brady  <P@draigBrady.com>

	tests: support more file systems in the cp fiemap tests
	* tests/cp/sparse-fiemap: Check for fiemap support against a file
	rather than a directory to enable tests on BTRFS for example.
	Explicity disable the test on ext3 or file systems where we
	can't determine the type.
	* tests/cp/fiemap-perf: Likewise.  Also disable the test on older
	BTRFS (like in Fedora 14), where extents are returned for holes.
	* tests/init.cfg: Comment that BTRFS only supports fiemap
	for regular files.

2011-02-11  Pádraig Brady  <P@draigBrady.com>

	copy: adjust fiemap handling of sparse files
	Don't depend on heuristics to detect sparse files
	if fiemap is available.  Also don't scan for new
	holes unless --sparse=always has been specified.

	sparse mode, and handle as described above.

2011-02-11  Pádraig Brady  <P@draigBrady.com>

	the source and dest files, when there is no hole between extents.

2011-02-10  Jim Meyering  <meyering@redhat.com>

	tests: fix bug in preceding check.mk change
	* tests/check.mk (.built-programs): Run cd'd submake in a subshell
	so the redirected output ends up in the current directory, not ../src.

	tests: print "python missing:..." diagnostic where more will see it
	* tests/init.cfg (fiemap_capable_): Print with warn_, so that the
	diagnostic shows up alongside the corresponding SKIP message.

	tests: avoid gross inefficiency in "make test"
	Do not run a sub-make to set up the environment for each
	and every test script.  Instead, run it just once and store
	the result in a file.
	* tests/check.mk (built_programs): Remove definition.
	(.built-programs): New rule to create the temporary file.
	(CLEANFILES): Arrange to remove it.

	* tests/cp/fiemap-perf: Comment why we're not enabling for ext3.
	* tests/cp/sparse-fiemap: Ditto.  Also sync the files before

	Add a comment that FIEMAP_FLAG_SYNC is ineffective, thus
	requiring the explicit syncs.
	* tests/fiemap-capable: A new python script to determine

	copy: don't let a failed lseek go undiagnosed
	Upon failed lseek, sparse_copy_finalize would mistakenly return true.
	Admittedly, that is very unlikely, since that particular lseek
	is attempted only if the preceding call to sparse_copy induced
	a hole at EOF (via lseek on the destination FD).  However, now
	that sparse_copy has an output parameter, N_READ, there is no
	longer any reason to call lseek (fd, 0, SEEK_CUR), so...
	* src/copy.c (sparse_copy_finalize): Remove the function.
	(copy_reg): Call ftruncate with n_read, rather than
	sparse_copy_finalize with its now-unnecessary lseek.
	Lasse Collin spotted the bug in sparse_copy_finalize.

	* NEWS: Record release date.

	cp: avoid spurious failure on any non-linux kernel
	* src/extent-scan.c (extent_scan_read) [!linux]: Always set

	This case was overlooked in commit bdde34f9, 2010-08-05,
	"sort: tune and refactor --debug code, and fix minor underlining bug"

	* src/sort.c (debug_key):  Don't adjust the key end when

2011-01-31  Pádraig Brady  <P@draigBrady.com>

	cp: fix the buffer size used when writing zeros
	* src/copy.c (write_zeros): This bug caused 4 or 8 bytes to
	be written at a time which is very inefficient.  One could
	trigger the issue with `cp --sparse=never sparse non-sparse`
	on a file system that supports fiemap.

2011-01-31  Jim Meyering  <meyering@redhat.com>

	cp: always initialize extent_copy's output parameter
	* src/copy.c (extent_copy): Otherwise it would be used uninitialized.

	tests: exercise a rarely-used corner of copy.c
	* tests/cp/sparse-to-pipe: New test.
	* tests/Makefile.am (TESTS): Add it.

	cp: fix copying a sparse file to a pipe
	The recent FIEMAP-related changes made it so the unusual case of
	copying a sparse file to a non-regular destination (e.g., a pipe)
	would erroneously write one byte too many to that destination.
	That happened because extent_copy assumed that it could use lseek
	to obtain the number of bytes written to the output file descriptor.
	That was valid only for regular files.
	* src/copy.c (sparse_copy): Add a parameter, to be used by extent_copy,
	but not by reg_copy.  Adjust callers.
	(extent_copy): Maintain new local, dest_pos, using new arg, n_read.
	Don't call lseek on dest_fd; use new var, dest_pos, instead.
	(copy_reg): Add unused arg.

	tests: gfs2 also supports FIEMAP
	* tests/init.cfg (fiemap_capable_): Add gfs2.
	Clarify comment.

	maint: remove unused inclusion of "fiemap.h"
	* src/copy.c: Don't include "fiemap.h".

	tests: factor fiemap-related predicate into init.cfg
	* tests/init.cfg (fiemap_capable_): New function.
	* tests/cp/fiemap-perf: Use it.
	* tests/cp/sparse-fiemap: Likewise.
	* tests/cp/fiemap-2: Likewise.

	maint: update copyright year lists in new files
	* src/extent-scan.h: Update copyright year list.
	* src/extent-scan.c: Likewise.
	* tests/cp/sparse-fiemap: Likewise.

	tests: modernize sparse-fiemap test
	* tests/cp/sparse-fiemap: Use print_ver_, not open-coded VERBOSE test.

	tests: remove duplicate fiemap-perf test
	* tests/cp/fiemap-perf: Copy block-comparing code from sparse-fiemap.
	* tests/cp/sparse-fiemap: The same test was here, alongside a much
	more involved test.  Remove it, now that it is in its own file.

2011-01-30  Jim Meyering  <meyering@redhat.com>

	doc: NEWS: mention cp's improvement
	* NEWS (New Features): cp now copies sparse files efficiently.

	build: update gnulib submodule to latest

	copy, tee: assume EINTR is always defined: remove #ifdefs
	Don't use "#ifdef EINTR".  dd.c has been doing that since 2004.
	* src/copy.c (sparse_copy): Remove #ifdef...#endif around EINTR use.
	* src/tee.c (tee_files): Remove #ifdef...#endif around EINTR use.
	If we need it, add something like this in system.h:
	/* When EINTR is not defined, define it to an improbable value
	   so that each use does not have to be #ifdef'd.  */
	 #ifndef EINTR
	 # define EINTR 999988
	 #endif

	tests: cp/fiemap: exercise previously-failing parts
	* tests/cp/fiemap-2: New test.
	* tests/Makefile.am (TESTS): Add it.

	copy: make extent_copy use sparse_copy, rather than its own code
	* src/copy.c (extent_copy): Before this change, extent_copy would fail
	to create holes, thus breaking --sparse=auto and --sparse=always.
	I.e., copying a large enough file of all zeros, cp --sparse=always
	should introduce a hole, but with extent_copy, it would not.

	copy: remove obsolete comment
	* src/copy.c (sparse_copy): Remove now-obsolete comment about
	how we used to work around lack of ftruncate.  Combine nested
	if conditions into one.

	copy: factor sparse-copying code into its own function, because
	we're going to have to use it from within extent_copy, too.
	* src/copy.c (sparse_copy): New function, factored out of...
	(copy_reg): ...here.
	Remove now-unused locals.

	fiemap copy: avoid leak-on-error
	* src/copy.c (extent_copy): Don't leak an extent_scan buffer on
	failed lseek, read, or write.

	fiemap copy: avoid a performance hit due to very small buffer
	* src/copy.c (extent_copy): Don't let what should have been a
	temporary reduction of buf_size (to handle a short ext_len) become
	permanent and thus impact the performance of all further iterations.

	fiemap copy: simplify post-loop logic; improve comments
	* src/copy.c (extent_copy): Avoid duplication in post-loop
	extend-to-desired-length code.

	fiemap copy: rename some locals
	(extent_copy): Rename locals: s/*ext_logical/*ext_start/

	tests: ensure that FIEMAP-enabled cp copies a sparse file efficiently
	* tests/cp/fiemap-perf: New file.
	* tests/Makefile.am (TESTS): Add it.

	copy: don't allocate a separate buffer just for extent-based copy
	* src/copy.c (copy_reg): Move use of extent_scan to just *after*
	we allocate the main copying buffer, so we can...
	(extent_scan): Take a new parameter, BUF, and use that rather
	than allocating a private buffer.  Update caller.

	copy: tweak variable name; improve a comment
	* src/copy.c (copy_reg): Rename a variable to make more sense from
	caller's perspective: s/require_normal_copy/normal_copy_required/.
	This is an output-only variable, and the original name could make
	it look like an input (or i&o) variable.

	copy: call extent_copy also when make_holes is false, ...
	so that we benefit from using extents also when reading a sparse
	input file with --sparse=never.
	* src/copy.c (copy_reg): Remove erroneous test of "make_holes"
	so that we call extent_copy also when make_holes is false.
	Otherwise, what's the point of that parameter?

	copy: remove else-after-goto and adjust indentation
	* src/copy.c (copy_reg): Remove useless else-after-goto.

	extent-scan: adjust naming and formatting
	* src/extent-scan.h [struct extent_scan]: Rename member:
	s/hit_last_extent/hit_final_extent/.  "final" is clearer,
	since "last" can be interpreted as "preceding".
	Rename extent-scan functions to start with extent_scan_.
	* src/Makefile.am (copy_sources): Also distribute extent-scan.h.
	* src/extent-scan.c: Don't include error.h or quote.h.  Neither is used.
	* src/copy.c: shorten a comment to fit in 80 columns
	* src/extent-scan.c, src/extent-scan.h: Correct formatting.

	fiemap copy: don't let write failure go unreported; adjust style, etc.
	* src/copy.c (write_zeros): Add comments.
	(extent_copy): Move decls of "ok" and "i" down to scope where used.
	Adjust comments.
	Rename local: s/holes_len/hole_size/
	Print a diagnostic upon failure to write zeros.

2011-01-30  jeff.liu  <jeff.liu@oracle.com>

	fiemap copy: add extent-scan.[ch], avoid a double-free and reorganize
	Changes:
	========
	1. fix write_zeros() per Jim's comments.
	2. remove char const *fname from struct extent_scan.
	3. change the signature of open_extent_scan() from
	"void open_extent_scan(struct extent_scan **scan)" to
	"void open_extent_scan(struct extent_scan *scan)" to avoid having
	to malloc the extent_scan variable; instead save it on the stack.
	4. move close_extent_scan() from a function defined in extent-scan.c
	to extent-scan.h as a macro definition, but it does nothing for now,
	since initial extent scan defined at stack.
	5. add a macro "free_extents_info()" defined at extent-scan.h to
	release the memory allocated to extent info which should be called
	combine with get_extents_info(), it just one line, so IMHO, define
	it as macro should be ok.

	* src/extent-scan.c: New file; functions to read "extents".
	* src/extent-scan.h: Header file of extent-scan.c.
	* src/Makefile.am: Reference it and link it to copy_source.
	* src/copy.c: Use the new functions and avoid double-free.

	copy.c: adjust comments, tweak semantics
	* src/copy.c (fiemap_copy): Rename from fiemap_copy_ok.
	Add/improve comments.
	Remove local, "fail".
	(fiemap_copy): Do not require caller to set
	"normal_copy_required" before calling fiemap_copy.
	Report ioctl failure if it's the 2nd or subsequent call.

	tests: relax the root-tests cross-check
	* cfg.mk (sc_root_tests): Allow spaces before "require_root_",
	now that tests/cp/sparse-fiemap has a conditional use.

	tests: accommodate varying filefrag -v "flags" output
	* tests/cp/sparse-fiemap: Accommodate values other than "eof"
	in the "flags" column of filefrag -v output

	tests: exercise more of the new FIEMAP copying code
	* tests/cp/sparse-fiemap: Ensure that a file with many extents
	(more than fit in copy.c's internal buffer) is copied properly.
	Don't require root access if current partition is btrfs or xfs.
	Use init.sh, not test-lib.sh.
	* tests/filefrag-extent-compare: New file.

	* src/copy.c (copy_reg): Now, when `cp' is invoked with --sparse=[WHEN],
	we will try to do FIEMAP-copy if the underlying file system
	supports it, and fall back to a normal copy if it fails.

2011-01-29  Pádraig Brady  <P@draigBrady.com>

	doc: add alternatives for field processing not supported by cut
	* doc/coreutils.texi (cut invocation): Remove the tr -s '[:blank:]'
	example, as it doesn't handle leading and trailing blanks.  Add `awk`
	examples for common field processing operations often asked about.
	Also document a `join` hack, to achieve the same thing.  Note the
	join options are ordered so as to be compatible with other systems.

2011-01-29  Pádraig Brady  <P@draigBrady.com>

	* src/join.c (join): Don't flag unpairable lines when
	one of the files is empty.

	join: add -o 'auto' to output a constant number of fields per line
	Lines with a different number of fields than the first line,
	will be truncated or padded.

	* src/join.c (prfields): A new function refactored from prjoin(),

	rawhide's gcc-4.6.0 would otherwise warn about use-uninitialized.

	tail: avoid new diagnostic when applying -f to a pipe on linux-2.3.38
	* src/tail.c (fremote): Do not print a diagnostic when
	fstatfs (pipe_FD, &buf) fails, as it now does on linux-2.3.38.
	This avoids the spurious failure of tests/misc/tail's f-pipe-1
	test, when running in input-from-pipe mode.

	maint: generate much of the THANKS file
	Before this change, we had a tendency to manually list each
	contributor's name in THANKS.  Now, each commit "Author" is
	included in the generated THANKS file automatically, and most
	of the old THANKS file is now a template, THANKS.in.
	We'll still have to manually list the names of people who report
	problems without a usable patch.

	* THANKS.in: New file, derived from THANKS, but removing names of
	those who are listed as git log 'Author:'s.
	* THANKS: Remove file.
	* thanks-gen: New file.
	* Makefile.am (THANKS): New rule.

	maint: allow gettext 0.17 again
	Commit 041c9c47 traded the 'gettext' module for the lighter 'gettext-h'
	module, so as to not require the latest gettext release (we only need
	the latest release if we ship gettext as a dependent library, but
	coreutils has long preferred to use it as an external library).
	But that commit overlooked two places necessary to allow the use of
	gettext 0.17.

	This does not force you to downgrade (using gettext 0.18.1.1 is still
	just fine), nor does it affect tarballs (once a tarball is built
	with a given gettext version, it can be built on other machines
	regardless of what gettext version is present).

	* bootstrap.conf (buildreq): Relax prerequisite.
	* configure.ac (AM_GNU_GETTEXT_VERSION): Likewise.

	csplit: diagnose file counter wraparound
	* src/csplit.c (create_output_file): Detect overflow when the

	sort: do not generate thousands of subprocesses for 16-way merge
	Without this change, tests/misc/sort-compress-hang would consume
	more than 10,000 process slots on my RHEL 5.5 x86-64 server,
	making it likely for other applications to fail due to lack of
	process slots.  With this change, the same benchmark causes 'sort'
	to consume at most 19 process slots.  The change also improved
	wall-clock time by 2% and user+system time by 14% on that benchmark.
	* NEWS: Document this.
	* src/sort.c (MAX_PROCS_BEFORE_REAP): Remove.
	(reap_exited): Renamed from reap_some; this is a more accurate name,
	since "some" incorrectly implies that it reaps at least one process.
	All uses changed.
	(reap_some): New function: it *does* reap at least one process.
	(pipe_fork): Do not allow more than NMERGE + 2 subprocesses.
	(mergefps, sort): Omit check for exited processes: no longer needed,
	and anyway the code consumed too much CPU per line when 2 < nprocs.

	sort: fix hang with sort --compress
	* NEWS: Document this.
	* src/sort.c (UNCOMPRESSED, UNREAPED, REAPED): New constants.
	(struct tempnode): New member 'state', to hold these constants.
	The pid member is now undefined if state == UNCOMPRESSED.
	(struct sortfile): Replace member 'pid' with member 'temp'.
	(uintptr): Remove.
	(proctab_hasher, proctab_comparator, register_proc, delete_proc):
	Proctab entries are now struct tempnode *, not pid_t, to handle
	the case where multiple tempnode objects correspond to the same
	pid.  This avoids a race condition that can cause a hang.
	(register_proc): Arg is now struct tempnode *, not pid_t.  All
	callers changed.
	(delete_proc): Set tempnode state to REAPED.
	(create_temp_file): No need to set pid member here; it's now
	done when the pid is known.
	(maybe_create_temp, create_temp): Remove PPID arg.  Return struct
	tempnode *, not char *.  All callers changed.
	(maybe_create_temp): Set node state to UNCOMPRESSED or UNREAPED.
	No need to set node->pid to 0.
	(open_temp): Replace NAME and PID args with a single TEMP arg.
	All callers changed.  Wait only for unreaped children.
	(zaptemp): Wait for decompressor to finish before removing its
	temporary-file input.  This avoids .nfsXXXX hassles with NFS
	and fixes a race (leading to a hang) regardless of NFS.
	(open_input_files): Adjust to new way of dealing with temp files
	and their subprocesses.
	* tests/Makefile.am (TESTS): Add misc/sort-compress-hang.
	* tests/misc/sort-compress-hang: New file.

	sort: don't dump core when merging from input twice
	* NEWS: Document this.
	* src/sort.c (avoid_trashing_input): The previous fix to this
	function didn't fix all the problems with this code.  Replace it
	with something simpler: just copy the input file.  This doesn't
	change the number of files, so return void instead of the updated
	file count.  Caller changed.

	doc: tail: semi-deprecate --sleep-interval and --max-unchanged-stats
	Those options are useful only on systems that lack inotify support
	and in the unusual event that a system with inotify support must
	resort to polling.
	* src/tail.c (usage): Note that the --max-unchanged-stats=N and
	--sleep-interval=N options are rarely useful on systems with
	inotify support.
	* doc/coreutils.texi (tail invocation): Likewise.

2010-12-14  Paul Eggert  <eggert@cs.ucla.edu>

	sort: fix very-unlikely buffer overrun when merging to input file
	* src/sort.c (avoid_trashing_input): Fix a typo that could cause a
	buffer overrun in theory.  In practice this is extremely unlikely,
	as it requires running out of file descriptors in a small merge,
	presumably because some other process is hogging all the OS's file
	descriptors.

	sort: document --compress reaper fixes
	* NEWS: Document the --compress reaper fixes installed yesterday.

	tests: default to /tmp as the temporary directory
	* tests/check.mk (TESTS_ENVIRONMENT): Default TMPDIR to /tmp,
	rather than to the working directory; this is more common in
	practice, which makes the tests more real-worldish; and it is
	often faster.  Also, it avoids some problems with NFS cleanups.
	* tests/misc/sort-compress: Remove unnecessary code setting TMPDIR.
	* tests/misc/sort-compress-proc: Likewise.  Do the final sleep
	only if TMPDIR is relative, which should be rarely given the
	change to TESTS_ENVIRONMENT.

	sort: fix some --compress reaper bugs
	* src/sort.c (uintptr): New type.
	(enum procstate, struct procnode, update_proc): Remove.
	(proctab_hasher, proctab_comparator, register_proc, wait_proc):
	(reap_some): The proctab is now simply a hash of process-IDs
	rather than of pointers to objects with reference counts and
	states; this is smaller and faster and easier to understand.
	(nprocs): Now pid_t, not size_t, since one cannot have more than
	PID_MAX children.
	(reap): If the argument is -1, wait; if 0 (a new value), do not.
	Delete pid from proctab as needed.  Ignore children that are not
	in proctab, as they are from the program that exec'ed us and are
	irrelevant to our success or failure.
	(delete_proc, reap_all): New functions.
	(open_temp): Register the child.
	(sort): Clean up all children afterwards; without this patch,
	'sort' sometimes missed failures in children due to race conditions.
	* tests/Makefile.am (TESTS): Add misc/sort-compress-proc.

	* tests/misc/printenv: Filter out LD_PRELOAD, as the comment
	said, not LD_LIBRARY.

	sort: avoid segfault when using two or more threads
	This change does not fix the actual bug.  That was done by commit
	c9db0ac6, "sort: preallocate merge tree nodes to heap".  The fix
	was to store each "node" structure on the heap, not on the stack.
	Otherwise, a node from one thread's stack could be used in another
	thread after the first thread had expired (via pthread_join).
	This bug was very hard to trigger when using spinlocks, but
	easier once we began using mutexes.
	* NEWS (Bug fixes): Mention it.
	For details, see http://debbugs.gnu.org/7597.

	sort: syntax cleanup
	* src/sort.c (xfopen, debug_key, sortlines, sort, main): Adjust
	formatting: fix misplaced braces, use consistent spacing,
	split a 2-stmt line.

2010-12-11  Paul Eggert  <eggert@cs.ucla.edu>

	sort: integer overflow checks in thread counts, etc.
	* src/sort.c (specify_nthreads, merge_tree_init, init_node):
	(queue_init, sortlines, struct thread_args, sort, main):
	Use size_t, not unsigned long int, for thread counts, since thread
	counts are now used to compute sizes.
	(specify_nthreads): Check for size_t overflow.
	(merge_tree_init, sort): Shorten name of local variable, for
	readability.
	(merge_tree_init): Move constants next to each other in product,
	so that the constant folding is easier to see.
	(init_node): Now static.  Add 'restrict' only where it might
	be helpful for compiler optimization.
	(queue_init): 2nd arg is now nthreads, not "reserve", which is
	a bit harder to follow.  All uses changed.
	(struct thread_args): Rename lo_child to is_lo_child, so that
	it's obvious to the reader when we're talking about this boolean
	as opposed to the new lo_child member of the other structure.
	All uses changed.
	(sort): Remove unused local variable end_node.
	(main): Don't allow large thread counts to cause undefined behavior
	later, due to integer overflow.

2010-12-11  Chen Guo  <chenguo4@ucla.edu>

	sort: preallocate merge tree nodes to heap.
	* src/sort.c: (merge_tree_init) New function. Allocates memory for
	merge tree nodes.
	(merge_tree_destory) New function.
	(init_node) New function.
	(sortlines) Refactor node creation code to init_node. Remove now
	superfluous arguments. All callers changed.
	(sort) Initialize/destory merge tree. Refactor root node creation
	to merge_tree_init.

2010-12-11  Paul Eggert  <eggert@cs.ucla.edu>

	sort: comment fix
	* src/sort.c: Comment fix re spin locks.

2010-12-11  Chen Guo  <chenguo4@ucla.edu>

	sort: use mutexes, not spinlocks (avoid busy loop on blocked output)
	Running a command like this on a multi-core system
	  sort < big-file | less
	would peg all processors at near 100% utilization.
	* src/sort.c: (struct merge_node) Change member lock to mutex.
	All uses changed.
	* tests/Makefile.am (XFAIL_TESTS): Remove definition, now that
	this test passes once again.  I.e., the sort-spinlock-abuse test
	no longer fails.
	* NEWS (Bug reports): Mention this.
	Reported by DJ Lucas in http://debbugs.gnu.org/7489.

2010-12-08  Pádraig Brady  <P@draigBrady.com>

	split: fix a case where --elide-empty causes invalid chunking
	When -n l/N is used and long lines are present that both
	span partitions and multiple buffers, one would get
	inconsistent chunk sizes.

	* src/split.c (main): Add a new undocumented ---io-blksize option
	to support full testing with varied buffer sizes.
	(cwrite): Refactor most handling of --elide-empty to here.
	(bytes_split): Remove handling of --elide-empty.
	(lines_chunk_split): Likewise.  The specific issue here
	was the first handling of elide_empty_files interfered
	with the replenishing of the input buffer.
	* test/misc/split-lchunk: Add -e and the new ---io-blksize
	combinations to the test.

2010-12-05  Jim Meyering  <meyering@redhat.com>

	tests: remove useless definition of $SORT in sort-compress
	* tests/misc/sort-compress (SORT): Remove unused definition.

2010-12-04  Jim Meyering  <meyering@redhat.com>

	tests: make it harder to lose a race in spinlock-abuse
	* tests/misc/sort-spinlock-abuse: On a busy system, with only 12
	pauses of length 0.1 seconds, the buggy (busy-spinlock blocked)
	sort would fail to accumulate 1 second of CPU time, and hence
	would mistakenly pass.  Increase from 12 to 50.

2010-12-04  Paul Eggert  <eggert@cs.ucla.edu>

	sort: merge_queue -> queue
	* src/sort.c (struct thread_args, sortlines_thread, sortlines, sort):
	Rename "merge_queue" to "queue", for consistency with other functions
	that just use the name "queue" for these things.

	sort: clarify queue_check_insert
	* src/sort.c (queue_check_insert): Clarify body a bit, and remove
	no-longer-needed comment.

	sort: fix problems with merge node dest pointer
	* src/sort.c (mergelines_node): Return void, not size_t.  All
	callers changed.  Change *node->dest here, not in caller.
	Do not change node->dest: it's not needed and could cause problems
	on (mostly theoretical) hosts that do not allow adding integers to
	null pointers.
	(queue_check_insert_parent): Omit MERGED parameter; no longer needed.
	All callers changed.

	sort: simplify write_unique
	* src/sort.c (write_unique): Simplify slightly so that there is
	just one call to write_line, not two.

	sort: put queue arg first
	* src/sort.c (queue_check_insert, queue_check_insert_parent): Make
	the queue arg first, for consistency with other functions such as
	queue_insert that put the queue arg first.  Rename from
	check_insert and update_parent, respectively.  All callers
	changed.

	sort: tune struct_merge_node slightly
	* src/sort.c (struct merge_node): 'lock' is now the actual lock,
	not a pointer to the lock; there's no need for indirection here.
	Make 'level' unsigned int instead of size_t, since it is a
	bit-shift count; also, move it next to a bool so that it's more
	likely to take less space.  All uses changed.
	(sortlines, sort): Spell out initialization instead of using an
	initializer.  This makes the initializer a bit easier to understand,
	and avoids unnecessary stores into the spin lock.

	sort: Clarify comments
	* src/sort.c: Improve comments a bit.

2010-12-03  Paul Eggert  <eggert@cs.ucla.edu>

	tests: cleanup rm -rf fails under NFS
	This problem was observed on RHEL 5.5 x86-64 when running as a
	client of a NetApp FAS2050.
	* tests/cp/cp-mv-backup: Don't leave a file descriptor open to
	a file in a directory that will be cleaned up with "rm -rf".
	Under NFS, when the rm unlinks that file, it is instead renamed
	to .nfsXXXX and then rm cannot remove the parent directory,
	and the test fails.
	* tests/cp/same-file: Likewise.

	cp: fix bug with fine-grained src to nearby coarse-grained dest
	The actual fix is in gnulib's lib/utimecmp.c.
	* NEWS: Document fix.

	build: update gnulib submodule to latest

2010-12-02  Paul Eggert  <eggert@cs.ucla.edu>

	sort: fix bug on 64-bit hosts with at least 32768 processors
	* src/sort.c (MAX_MERGE): Avoid integer overflow when on a machine
	with (say) 32-bit int and 64-bit size_t and when level == 15.
	Without this fix, on such a machine with 32768 or more processors,
	the level computation could overflow on large input, and this
	would result in division by zero.

2010-12-01  Jim Meyering  <meyering@redhat.com>

	tests: add test for parallel sort -u segfault bug
	* tests/misc/sort-unique-segv: New file.
	* tests/Makefile.am (TESTS): Add it.

2010-12-01  Paul Eggert  <eggert@cs.ucla.edu>

	sort -u: fix a thread-race pointer corruption bug
	* src/sort.c (write_unique): Save the entire "struct line", not
	just a pointer to one.  Otherwise, with a multi-thread run,
	sometimes, with some inputs, fillbuf would would win a race
	and clobber a "saved->text" pointer in one thread just before
	it was dereferenced in a comparison in another thread.
	* NEWS (Bug fixes): Mention it.

2010-11-27  Jim Meyering  <meyering@redhat.com>

	tests: don't let the OMP_NUM_THREADS envvar affect sort tests

2010-11-27  Pádraig Brady  <P@draigBrady.com>

	tsort: suppress a valgrind memory leak warning
	* src/tsort.c (tsort): Unconditionally invoking the free()
	doesn't increase scalability, so do it only with -Dlint

2010-11-24  Pádraig Brady  <P@draigBrady.com>

	maint: update the valgrind support script
	* README-valgrind: Include the "noinst" programs in
	those wrapped by valgrind.  Update $PATH in check.mk
	rather than Makefile.am.  Make wrapper scripts
	work when suppressions not setup.  Keep lines < 80 chars.

2010-11-22  Paul Eggert  <eggert@cs.ucla.edu>

	cp: give a better diagnostic for nonexistent dest/
	This patch was written by Jim Meyering and myself.
	* src/copy.c (copy_reg): Turn EISDIR to ENOTDIR to improve the
	quality of diagnostics for commands like "cp a nosuch/".  Reported
	by Марк Коренберг and Alan Curry in the thread starting at:
	http://lists.gnu.org/archive/html/bug-coreutils/2010-11/msg00178.html
	* THANKS: Update.
	* tests/mv/trailing-slash: Add a test.

2010-11-22  Chen Guo  <chen.guo.0625@gmail.com>

	split: add --number to generate a particular number of files

	od: fix bugs in displaying floating-point values
	* NEWS: Describe patch.
	* bootstrap.conf (gnulib_modules): Add ftoastr.
	* src/od.c: Include ftoastr.h, not float.h.
	(FLT_DIG, DBL_DIG): Remove.  No need to verify LDBL_DIG.
	(FMT_BYTES_ALLOCATED): No need to worry about floating point now,
	since this format is no longer used for floating point.
	(PRINT_FIELDS): New macro, with most of the guts of the old PRINT_TYPE.
	(PRINT_TYPE): Rewrite to use PRINT_FIELDS.
	(PRINT_FLOATTYPE): New macro.  This uses the new functions from

	tests: convert tests/misc/selinux manually

2010-11-17  Jim Meyering  <meyering@redhat.com>

	tests: convert the multi-prog $VERBOSE/--version uses
	E.g.,

	-test "$VERBOSE" = yes && { env -- pwd --version; readlink --version; }
	+print_ver_ pwd readlink

	-test "$VERBOSE" = yes && { stdbuf --version; mv --version; }
	+print_ver_ stdbuf mv

	Use this command:

	  -e 's/env -- //g;' \
	  -e 's/test "\$VERBOSE" = yes && { /print_ver_ /;' \
	  -e ' s/(\w+) --version;/$1/g; s/ *}$//; print'

2010-11-17  Jim Meyering  <meyering@redhat.com>

	tests: convert "... env -- prog --version" uses
	E.g.,

	-test "$VERBOSE" = yes && env -- pwd --version
	+print_ver_ pwd

	git grep -l 'VERBOSE.*--version'|xargs perl -pi -e \
	  's/test "\$VERBOSE" = yes && env -- (\w+) --version/print_ver_ $1/'

2010-11-17  Jim Meyering  <meyering@redhat.com>

	tests: substitute the single-program $VERBOSE/--version uses
	Automatically make all of the changes like this:

	  -test "$VERBOSE" = yes && chgrp --version
	  +print_ver_ chgrp

	git grep -l 'VERBOSE.*--version'|xargs perl -pi -e \
	  's/test "\$VERBOSE" = yes && (\w+) --version/print_ver_ $1/'

2010-11-17  Jim Meyering  <meyering@redhat.com>

	tests: factor out VERBOSE-only --version-printing code
	* tests/init.cfg (print_ver_): New function.

	tests: remove test-lib.sh; now all tests use gnulib's init.sh
	* tests/test-lib.sh: Remove file.  No longer used.
	* tests/Makefile.am (EXTRA_DIST): Remove it here, too.
	* tests/sample-test: Correct a comment.

	tests: convert remaining uses of test-lib.sh to init.sh
	RHS='. "\${srcdir=.}/init.sh"; path_prepend_ ../src'
	git grep -l test-lib.sh \
	  | xargs perl -pi -e 's,^\. \$srcdir/test-lib\.sh$,'"$RHS",

	tests: convert 'if test "$VERBOSE" = yes; then' to test ... &&

2010-11-17  Jim Meyering  <meyering@redhat.com>

	tests: convert first batch of tests from test-lib.sh to init.sh
	Initially, I did this,
	git grep -l srcdir/test-lib.sh|xargs perl -p0i -e '~180-byte script'
	but that line would have been much longer than the maximum permitted
	by coreutils' commit hook, and wasn't readable besides, so here's a
	more readable version:

	lhs=$(printf '%s\\n' \
	'if test "$VERBOSE" = yes; then' \
	'  set -x' \
	'  touch --version' \
	'fi' \
	'' \
	'. $srcdir/test-lib.sh' \
	  | sed 's/\$/\\\$/g;s/touch/(\\w+)/')

	rhs=$(printf '%s\\n' \
	'. "${srcdir=.}/init.sh"; path_prepend_ ../src' \
	'test "$VERBOSE" = yes && FIXME --version' \
	  | sed 's/\$/\\\$/g;s/FIXME/\$1/')

	git grep -l srcdir/test-lib.sh|xargs perl -p0i -e "s,$lhs,$rhs,"

2010-11-17  Jim Meyering  <meyering@redhat.com>

	tests: move a comment so automated conversion works

	maint: add a NEWS-checking syntax-check rule

	by gnulib-tool to apply local diffs to gnulib modules

	split: fail immediately if impossible to create a large file
	* src/split.c (main): Error if -[bC] value > OFF_T_MAX
	* tests/misc/split-fail: Adjust for the new lower limits

	truncate: fix a very unlikely case for undiagnosed errors
	src/truncate.c (main): Use a bool to store if an error occurred,

	(do_ftruncate): Likewise.   Also change 0/false to mean failure
	rather than success.

	maint: fix a new -Wpointer-sign gcc warning
	* src/csplit.c (max_out): Fix a new warning introduced with
	commit 6568b173, 2010-11-10, "csplit: do not rely on..."

2010-11-16  Pádraig Brady  <P@draigBrady.com>

	build: enable the -Wpointer-sign gcc warning

	This follows on from commit 34ef0a01, 2010-10-14,
	"sort: fix unportable cast of unsigned char * -> char *"

	build: update gnulib for linux 2.6.9 nanosleep workaround
	Also, do the following to avoid "make syntax-check" failure
	induced by new rules.
	* .x-sc_bindtextdomain: Exempt files with an #ifdef'd "main".
	* Makefile.am: Add this file.

	maint: remove fstimeprec (variable precision time stamp) support
	The implementation of variable-precision time stamps relied
	on heuristics that made the output subtly nondeterministic,
	or at least hard to reproduce:
	http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/21531/focus=21538
	So, for now at least, we're removing that feature.
	* bootstrap.conf (gnulib_modules): Remove fstimeprec.
	* gl/lib/fstimeprec.c, gl/lib/fstimeprec.h: Remove files.
	* gl/modules/fstimeprec, gl/modules/fstimeprec-tests: Likewise.
	* gl/tests/test-fstimeprec.c: Remove file.

	stat: do not provide variable precision time stamps
	* src/stat.c: Don't include fstimeprec.c.

2010-11-11  Paul Eggert  <eggert@cs.ucla.edu>

	csplit: do not rely on undefined behavior in printf formats
	* doc/coreutils.texi (csplit invocation): Say that %d and %i are
	aliases for %u.
	* src/csplit.c (FLAG_THOUSANDS, FLAG_ALTERNATIVE): New constants.
	(get_format_flags): Now take char const * and int * and return
	size_t.  It now stores info about the flags instead of merely
	scanning them.  Also, it handles '0' correctly.  Drop support for
	the undocumented '+' and ' ' flags since the value is unsigned.
	Add support for the (undocumented) "'" flag.  All uses changed.
	(get_format_width, get_format_prec): Remove.
	(check_format_conv_type): Renamed from get_format_conv_type, with
	a different signature.  It now converts the format to one that is
	compatible with unsigned int, and checks flags.  All uses changed.
	(max_out): Have snprintf compute the number of bytes needed rather
	than attempting to do it ourselves (which doesn't work portably
	with outlandish formats such as %4294967296d).
	(check_format_conv_type, main): Check for overflow in size
	calculations.  Don't assume size_t fits in unsigned int.
	* tests/misc/csplit: Check for proper handling of flags, with
	%0#6.3x.  Coreutils 8.6 mishandles this somewhat-weird example.

	tests: don't disqualify FreeBSD 8.1's /bin/sh just yet,
	because dash-0.5.6-2.fc14.x86_64 would also be disqualified.
	This reverts part of yesterday's commit 6c058b2d, "tests: avoid
	failure due to bug in FreeBSD 8.1's /bin/sh".  Note that the offending
	aspect of those shells is not officially a bug, since "local" is not
	specified by POSIX.  However, it is very unintuitive that prepending
	"local" to an existing, standards-compliant assignment would evoke
	such a fundamental change in semantics.
	* tests/init.sh: Remove snippet requiring sane "local" support.

	stat: revert %X-%Y-%Z change; use e.g., %:X to print fractional seconds
	This reverts part of the recent commit 9069af45,
	"stat: print timestamps to full resolution", which made %X, %Y, %Z

	bug#7213: [PATCH] sort: fix buffer overrun on 32-bit hosts when warning re obsolete keys
	* src/sort.c (key_warnings): Local buffer should be of size
	INT_BUFSIZE_BOUND (uintmax_t), not INT_BUFSIZE_BOUND (sword).
	This bug was discovered by running 'make check' on a 32-bit
	Solaris 8 sparc host, using Sun cc.  I saw several other instances
	of invoking umaxtostr on a buffer declared to be of size
	INT_BUFSIZE_BOUND (VAR), and these instances should at some point
	be replaced by INT_BUFSIZE_BOUND (uintmax_t) too, as that's a
	less error-prone style.

	tests: work around portability and clock-skew problems
	* tests/misc/ls-misc (push_ls_colors): Don't assume LS_COLORS
	is set.  This part of the fix is by Jim Meyering.
	(sl-dangle2, sl-dangle3, sl-dangle4, sl-dangle5): Don't assume
	that newly-created files will have time stamps in the past.  They
	might not, due to clock skew, if the file systems are remote.

	install: avoid warning with Solaris 10 cc
	* src/install.c (extra_mode): Don't assign ~S_IRWXUGO & ~S_IFMT
	to a mode_t variable, as the number might be too big to fit.
	Solaris 10 cc warns about this, and the C standard says it
	has undefined behavior.

	mbsalign: avoid warning with Solaris 10 cc
	* gl/lib/mbsalign.c: Include <stdint.h> for SIZE_MAX.
	Use SIZE_MAX rather than (size_t) -1, to avoid warning for
	"size_t x = -1" on Solaris 10 cc.
	* gl/modules/mbsalign (Depends-on): Add stdint.

	sort: fix unportable cast of unsigned char * -> char *
	* src/sort.c (fold_toupper): Change this back from char to
	unsigned char, fixing a portability issue introduced in commit
	59e2e55d0f154a388adc9bac37d2b45f2ba971f8 dated February 26, as the
	C Standard doesn't let you convert from unsigned char * to char *
	without a cast, and the (in theory more portable) style here is to
	convert char values, not pointer values.
	(getmonth): Convert char to unsigned char when needed for
	comparison.

	tail: fix checking of currently unavailable directories
	* src/tail.c (tail_forever_inotify): Handle the case where
	tail --follow=name with inotify, is not able to add a watch on
	a specified directory.  This may happen due to inotify resource
	limits or if the directory is currently missing or inaccessible.
	In all these cases, revert to polling which will try to reopen
	the file later.  Note inotify returns ENOSPC when it runs out
	of resources, and instead we report a particular error message,
	lest users think one of their file systems is full.
	(main): Document another caveat with using inotify, where we
	currently don't recheck directories recreated after the
	initial watch is setup.
	* tests/tail-2/F-vs-rename: Fix the endless loop triggered by
	the above issue.
	* tests/tail-2/inotify-hash-abuse: Likewise.

	stat: optimize and translate default format strings
	Yes, this patch intentionally leaks the results of default_format(),
	since it is called only twice, and since the results are in scope
	until main() exits.  Not worth the extra code to pacify valgrind.

	* src/stat.c (main): Hoist default format computation out of loop.
	(do_statfs, do_stat): Move default format generation...
	(default_format): ...into new function.  Allocate the result in

	tr: fix various issues with case conversion
	This valid translation spec aborted:
	  LC_ALL=en_US.iso-8859-1 tr '[:upper:]- ' '[:lower:]_'
	This invalid translation spec aborted:
	  LC_ALL=en_US.iso-8859-1 tr '[:upper:] '  '[:lower:]'
	This was caused by commit 6efd1046, 05-01-2008,
	"Avoid tr case-conversion failure in some locales"

	This misaligned conversion spec was allowed:
	  LC_ALL=C tr 'A-Y[:lower:]' 'a-z[:upper:]'
	This was caused by commit af5d0c36, 21-10-2007,
	"tr: do not reject an unmatched [:lower:] or [:upper:] in SET1"

	This misaligned spec was allowed by extending the class:
	  LC_ALL=C tr '[:upper:] ' '[:lower:]'

	* src/tr.c (validate_case_classes): A new function to check
	alignment of case conversion classes.  Also it adjusts the
	length of the sets so that locales with different numbers of
	upper and lower case characters, don't cause issues.
	(string2_extend): Disallow extending the case conversion
	class as in the above example.  That is locale dependent
	and most likely not what the user wants.
	(validate): Do the simple test for "restricted" char classes
	earlier, so we don't redundantly do more expensive validation.
	(main): Remove the case class validation, and simplify.
	* tests/misc/tr-case-class: A new test to test the various
	alignment and locale issues, associated with case conversion.
	* tests/misc/tr: Move case conversion tests to new tr-case-class.

	join: improve performance when operating on whole lines
	Following on from commit f86bb696, 01-02-2010,
	"join: make -t '' operate on the whole line".
	Bypassing the delimiter search in this case,
	gives about an 8% performance boost.

	* src/join (xfields): Don't bother looking for '\n'
	in the data, which we know won't be present.

2010-08-28  Jim Meyering  <meyering@redhat.com>

	tac: avoid double free
	* src/tac.c (main): Reading a line longer than 16KiB would cause
	tac to realloc its primary buffer.  Then, just before exit, tac
	would mistakenly free the original (now free'd) buffer.
	This bug was introduced by commit be6c13e7, "maint: always free a
	buffer, to avoid even semblance of a leak".
	* NEWS (Bug fixes): Mention it.

	sort, who: prefer free+malloc to realloc when contents are irrelevant
	This change was prompted by the previous one: I audited the code
	looking for similar examples.  Too bad valgrind doesn't catch this.
	* src/sort.c (check, mergefps): xrealloc -> free + xmalloc
	* src/who.c (print_user): Likewise.

2010-08-10  Paul Eggert  <eggert@cs.ucla.edu>

	sort: free/xmalloc rather than xrealloc
	* src/sort.c (compare_random): Use free/xmalloc rather than

	Also, don't fail if the guessed-sized malloc fails.  Suggested by
	Bruno Haible.

2010-08-09  Paul Eggert  <eggert@cs.ucla.edu>

	sort: speed up -R with long lines in hard locales
	* src/sort.c (compare_random): Guess that the output will be
	3X the input.  This avoids the overhead of calling strxfrm
	twice on typical implementations.  Suggested by Bruno Haible.

2010-08-07  Paul Eggert  <eggert@cs.ucla.edu>

	sort: support all combinations of -d, -f, -i, -R, and -V
	* NEWS: Document this.
	* src/sort.c (getmonth): Omit LEN arg, as MONTH is now null-terminated.
	(compare_random): Don't null-terminate keys, as caller now does that.
	(compare_version): Remove.
	(debug_key): Null-terminate string for getmonth.
	(keycompare): Support combining -R with any of -d, -f, -i, -V.
	Also, support combining -V with any of -d, -i.
	(check_ordering_compatibility): Allow newly-supported combinations.
	* tests/misc/sort (02q, 02r, 02s): New tests, for new combinations.
	(incompat2): Now test -nR, since -fR are now compatible.

2010-08-05  Paul Eggert  <eggert@cs.ucla.edu>

	sort: tune and refactor --debug code, and fix minor underlining bug
	Formerly, the 'compare' function and some of its subroutines had a
	debugging flag, which caused them to output underlines.  This
	change refactors the code so that debugging output is
	more-separated from the actual sorting.  In the process, the
	change fixes a minor error in the debugging output.  The change
	shortens the source code and executable size a tad, and improves
	CPU performance by 2.4% on my platform with a simple benchmark (C
	locale, line sorting, no debug).

	* src/sort.c (long_double, strtold): Move back to prelude, since
	they're now used by multiple functions again.
	(unit_order): Move to file scope, since it's now used by two functions.
	(find_unit_order, human_numcompare, numcompare, general_numcompare):
	Remove endptr parameter.  All callers changed.
	(human_numcompare): Args are now const pointers.
	(getmonth): Endptr is now non-const.
	(key_numeric): Move up, since it's needed earlier.
	(debug_key): Take a line and a key as argument, instead of having
	the caller figure out where the field is.
	(debug_line): New function.
	(keycompare, compare): Omit debug parameter; debug output now done
	elsewhere.  All callers changed.
	(write_line): Renamed from write_bytes; all callers changed.
	Use debug_line (not 'compare') to output debug info.
	Use a slightly faster check for whether output file is stdout.
	(check): Don't do debugging output; it's not that useful here,
	and it confuses the code.
	(main): Check for incompatibility between -c and --debug.
	Use standard diagnostic for incompatible options.
	* tests/misc/sort-debug-keys: Fix test case: "--Mi-1" is not
	a number, so its first character should not be underlined when
	debugging a numeric sort.

2010-08-05  Paul Eggert  <eggert@cs.ucla.edu>

	sort: -R now uses less memory on long lines with internal NULs
	* lib/Makefile.am (libcoreutils_a_SOURCES): Remove xmemxfrm.c,
	xmemxfrm.h.
	* lib/memxfrm.c, lib/memxfrm.h, lib/xmemxfrm.c, lib/xmemxfrm.h: Remove.
	* m4/memxfrm.m4: Likewise.
	* m4/prereq.m4 (gl_PREREQ): Remove gl_MEMXFRM.
	* po/POTFILES.in: Remove lib/xmemxfrm.c.
	* src/sort.c: Don't include xmemxfrm.h.
	(cmp_hashes): Remove.
	(xstrxfrm): New function.
	(compare_random): If a line contains NULs, don't create a big
	buffer that contains the strxfrm output of each string in the line.
	Instead, accumulate checksums and differences as we go, so that
	at any one time we have to store at most the output of a single
	strxfrm call when processing the line.  This removes the need for
	an memxfrm function.

2010-08-03  Paul Eggert  <eggert@cs.ucla.edu>

	init.sh: work around trap limitation of some shells
	* tests/init.sh (setup_): Move exit trap outside of shell function.
	This patch is imported from gnulib.

	sort: fix bug in --debug when \0 is followed by \t
	* src/sort.c (debug_width): New function, which does not stop
	counting tabs at \0, and also invokes mbsnwidth.  Stamp out strnlen!
	(count_tabs): Remove.
	(debug_key): Use debug_width instead of mbsnwidth and count_tabs.
	* tests/misc/sort-debug-keys: Check that \0 and \t intermix.

	sort: revert recent -h changes and use a more-conservative approach
	* NEWS: Document changes to sort -h, which are now minor with
	respect to the pre-July-30th version.
	* doc/coreutils.texi (sort invocation): Likewise.  The
	documentation now describes how -h comparison is done rather than
	being vague with border cases.
	* src/sort.c (long_double, strtold): Move back to general_numcompare.
	(LD, compute_human): Remove.
	(find_unit_order): Remove THOU_SEP parameter, since thousands
	separators are now allowed by all callers.  Revert to previous
	behavior of sorting by suffix, and returning the order rather than
	2 * order + binary, since we no longer care whether binary powers
	are being used.  However, treat all zeros the same, instead of
	sorting 0M before 0G; this is more consistent with the desired
	behavior of sorting -1G before -1M.
	* tests/misc/sort (h1, h3, h6): Adjust to match mostly-reverted
	behavior.  However, check that all zeros sort together.
	* tests/misc/sort-debug-keys: Omit a "_", since the trailing "i"
	in "1234Gi" is no longer part of the key.

2010-07-30  Paul Eggert  <eggert@cs.ucla.edu>

	sort: -h now handles comparisons such as 6000K vs 5M and 5MiB vs 5MB
	* NEWS: Document changes to sort -h.
	* doc/coreutils.texi (sort invocation): Likewise.
	* src/sort.c (long_double, strtold): Move to prelude, since they're
	now used by multiple functions.
	(LD): New macro.
	(struct keyfield.iec_present): Remove this member.  All uses removed.
	(check_mixed_SI_IEC): Remove.  This code was busted in the presence
	of multiple threads, as it had a race condition.
	(find_unit_order): Remove arg KEY; add arg THOU_SEP; arg ENDPTR is
	now char ** rather than char const **.  Return an integer that
	distinguishes decimal from binary powers.  Parse the number
	consistently with the intersection of strtold and strnumcmp.
	Set *ENDPTR unconditionally.
	(compute_human): New static function.
	(human_numcompare): Remove arg KEY.  Remove 'const' from other args.
	Use strnumcmp if possible, but fall back on floating point if not.
	(numcompare, general_numcompare): Arg EA is now char ** rather
	than char const **.
	(numcompare): Adjust to new find_unit_order signature and behavior.
	(keycompare): Adjus to new human_numcompare signature.
	* tests/misc/sort (h1, h3, h4, h6): Adjust to new behavior.
	* tests/misc/sort-debug-keys: Likewise.

2010-07-27  Paul Eggert  <eggert@cs.ucla.edu>

	sort: fix --debug display with very large offsets
	* src/sort.c (mark_key): Don't assume offset <= INT_MAX.
	Make the code a bit clearer when width != 0.

	sort: fix bug with EOF at buffer refill
	* src/sort.c (fillbuf): Don't append eol unless the line is nonempty.
	This fixes a bug that was partly but not completely fixed by
	the aadc67dfdb47f28bb8d1fa5e0fe0f52e2a8c51bf commit (dated July 15).
	* tests/misc/sort (realloc-buf-2): New test, which catches this
	bug on 64-bit hosts.

	sort: omit some "inline"s
	* src/sort.c (mergelines, queue_destroy, queue_init, queue_insert):
	(queue_pop, write_unique, mergelines_node, check_insert):
	(update_parent): No longer inline; these uses of "inline"
	seemed unlikely to help performance much.

2010-07-26  Paul Eggert  <eggert@cs.ucla.edu>

	sort: don't assume ASCII when parsing K, M, G suffixes
	* src/sort.c (find_unit_order): Don't assume ASCII.

2010-07-26  Paul R. Eggert  <eggert@cs.ucla.edu>

	sort: make struct heap private
	* gl/lib/heap.c (struct heap): Move this here...
	* gl/lib/heap.h (struct heap): ... from here, as outside code no
	longer needs to access any of these members.

	sort: omit unnecessary mutex unlock+lock; simplify heap access
	* src/sort.c (queue_pop): Omit unnecessary unlock+lock after
	pthread_cond_wait returns.  Don't access "count" member of the
	heap; any efficiency gains should be quite minor, the access
	complicates this code, and "count" should be private anyway.

	sort: omit 'restrict' in doubtful cases
	* src/sort.c (lock_node, unlock_node, queue_destroy, queue_init):
	(queue_pop):
	Omit 'restrict'; it shouldn't help here, as these functions have just
	one pointer parameter and don't access static storage.
	(queue_insert, check_insert, update_parent): Omit 'restrict', as
	the pointer types differ, and are not char * or unsigned char *,
	and therefore can't alias.
	(write_unique): Omit 'restrict', as the pointer types are all
	read-only.
	(merge_loop, sortlines): Omit 'restrict', as any performance
	advantages are extremely unlikely and it's not worth cluttering
	the code for that.
	(struct thread_args): Omit 'restrict': this seems to be incorrect.
	It's unlikely for 'restrict' to be correct inside a typedef.

	sort: omit unnecessary casts
	* src/sort.c (inittables, general_numcompare, compare_nodes):
	(queue_init, queue_pop): Omit casts that are not needed, typically
	because they are between void * and some other pointer type.

	sort: use more-consistent style with const
	* src/sort.c (proctab_hasher, proctab_comparator, stream_open, xfopen):
	(open_temp, zaptemp, struct_month_cmp, begfield, limfield):
	(find_unit_order, human_numcompare, numcompare, general_numcompare):
	(count_tabs, keycompare, compare, compare_nodes, lock_node):
	(unlock_node, queue_destroy, queue_init, queue_insert, queue_pop):
	(write_unique, mergelines_node, check_insert, update_parent):
	(merge_loop, sortlines, struct thread_args, set_ordering):
	Prefer the style "T const" to "const T".
	* gl/lib/heap.h (struct heap, heap_alloc): Likewise.
	* gl/lib/heap.c (heap_default_compare, heapify_down, heapify_up):
	(heap_alloc): Likewise.

2010-07-25  Paul Eggert  <eggert@cs.ucla.edu>

	du: add NEWS entry for recent du -L fixes

2010-07-24  Paul R. Eggert  <eggert@cs.ucla.edu>

	du: tune, and fix some -L bugs with dangling or cyclic symlinks
	* src/du.c (process_file): Avoid recalculation of hashes
	and of file-exclusion for directories.  Do not descend into
	the same directory more than once, unless -l is given; this is faster.
	Calculate stat buffer lazily, since it
	need not be computed at all for excluded files.
	Count space if FTS_ERR, since stat buffer is always valid then.
	No need for 'print' local variable.
	(main): Use FTS_NOSTAT.  Use FTS_TIGHT_CYCLE_CHECK only when not
	hashing everything, since process_file finds cycles on its own
	when hashing everything.
	* tests/du/deref: Add test cases for -L bugs.

	tests/misc/sort-merge-fdlimit: don't assume -R opens /dev/urandom
	* tests/misc/sort-merge-fdlimit: This test was written assuming that
	-R typically opens /dev/urandom, but that's no longer the case.
	Redo test to specify a random source; this resurrects the point of
	checking for file descriptor exhaustion.  Also try plain -R, since
	that implementation may change in the future too.

2010-07-23  Paul R. Eggert  <eggert@cs.ucla.edu>

	randread: run 2x faster on 64-bit hosts, don't assume no padding bits
	* gl/lib/rand-isaac.c: 	Remove the I/O; this belongs elsewhere.
	Add support for ISAAC64.  Port to hosts with padding bits.
	Add self to author list.  Include <limits.h>, for CHAR_BIT.
	Don't include string.h, sys/time.h, unistd.h.
	(min, just): New functions.
	(IF32): New macros.
	(ind, ISAAC_STEP, isaac_refill, mix, isaac_init, isaac_seed):
	Add support for ISAAC64.  Port to hosts with padding bits.
	(ind): Now an inline function rather than a macro; no need for it
	to be a macro with modern compilers.
	(ISAAC_STEP): Renamed from isaac_step, since it's not function-like.
	Don't bother to pass args that are always the same.  All uses changed.
	(ISAAC_STEP, ISAAC_SEED): Move to inside the only function body
	that can use it.
	(ISAAC_MIX): Renamed from isaac_mix, since it's now a macro and is
	no longer function-like.  Don't bother saving and restoring state;
	no longer needed now that we're not a function.  All uses changed.
	(isaac_seed_start, isaac_seed_data, isaac_seed_finish): Remove.
	(isaac_seed): Take just the one arg; the caller now sets s->m.
	* gl/lib/rand-isaac.h: Use _GL_RAND_ISAAC_H to protect, instead
	of RAND_ISAAC_H.  Try out " #" rather than "# " for indenting.
	(ISAAC_BITS_LOG, ISAAC_BITS): New macros.
	(ISAAC_WORDS_LOG): Renamed from ISAAC_LOG.
	(isaac_word): New type.  All uses of uint32_t changed to isaac_word,
	to support ISAAC64.
	(struct isaac_state): Rename member MM to M, and make it public.
	(isaac_seed, isaac_refill): Adjust to new API.
	* gl/lib/randread.c: Include sys/time.h.
	(get_nonce): New function, containing the nonce stuff that used
	to be in rand-isaac.c but better belongs here.
	(randread_new): Use it.
	* gl/modules/randread (Depends-on): Add inline.
	* gl/modules/randread-tests: New file.
	* gl/tests/test-rand-isaac.c: New file.

2010-07-16  Paul R. Eggert  <eggert@cs.ucla.edu>

	randread: don't require -lrt
	Programs like 'sort' were linking to -lrt in order to get

	(tail_LDADD, uptime_LDADD): Omit $(POW_LIB), as it's no longer
	needed due to recent gnulib changes, where the strtod module no
	longer uses the pow function.  strtold needs pow only because it's
	sometimes aliased to strtod.  See

	routines will not return NULL.  Also remove the redundant
	temporary variables.
	(heap_insert): From Jim Meyering, use x2nrealloc() which
	is simpler while handling overflow and increasing the
	size more efficiently.  This reallocation is currently
	unused by coreutils in any case as it preallocates enough.

2010-07-13  Chen Guo  <chenguo4@yahoo.com>

	sort: parallelize internal sort
	This patch is by Gene Auyeung, Chris Dickens, Chen Guo, and Mike
	Nichols, based off of a patch by Paul Eggert, Glen Lenker, et. al.,
	with a basic heap implementation based off of the GDSL heap,
	originally by Nicolas Darnis.

	The number of sorts done in parallel is limited to the number
	of available processors by default, or can be further restricted
	with the --parallel option.

	On a dual-die, 8 core Intel Xeon, results show sorting with
	8 threads is almost 4 times faster than using a single thread.
	Timings when sorting a 96MB file:
	THREADS     TIME (s)
	1            5.10
	2            2.87
	4            1.75
	8            1.31

	Single threaded sorting has also been improved,
	especially for cheaper comparison operations:
	COMMAND             BEFORE (s)  AFTER (s)
	sort                 8.822       8.716
	sort -g             10.336      10.222
	sort -n              3.077       2.961
	LANG=C sort          2.169       2.066

	Now allocates the object rather than initializing it.
	For now, this no longer takes an initial size; we can put this
	back later if it is needed.
	* gl/lib/di-set.c: Include hash.h, ino-map.h, and limits.h instead of

	(do_stat): Likewise.
	I nearly forgot to update do_stat to propagate print_it failure,

	du: increase the initial dev-inode set size
	* src/du.c (INITIAL_DI_SET_SIZE): Increase to the prime just under
	1024.  This gives a speed-up of about 2% when processing a tree
	containing 100,000 files, each with a link count greater than 1,
	all pointing to files in some other tree.

2010-07-04  Jim Meyering  <meyering@redhat.com>

	du: use less than half as much memory when tracking hard links
	When processing a hard-linked file, du must keep track of the file's
	device and inode numbers in order to avoid counting its storage
	more than once.  When du would process many hard linked files --
	as are created by some backup tools -- the amount of memory required
	for the supporting data structure could become prohibitively large.
	This patch takes advantage of the fact that the amount of information
	in the numbers of the typical dev,inode pair is far less than even
	32 bits, and hence usually fits in the space of a pointer, be it
	32 or 64 bits wide.  A typical du traversal examines files on no
	more than a handful of distinct devices, so the device number can
	be encoded in just a few bits.  Similarly, few inode numbers use
	all of the high bits in an ino_t.  Before, we would represent the
	dev,inode pair using a naive struct, and allocate space for each.
	Thus, an entry in the hash table consisted of a pointer (to that
	struct) and a "next" pointer.  With this change, we encode the
	dev,inode information and put those bits in place of the pointer,
	and thus do away with the need to allocate additional space for
	each dev,inode pair.

	* src/du.c: Include "di-set.h".
	Don't include "hash.h"; it's no longer used.
	(INITIAL_DI_SET_SIZE): Define.
	(di_set): New global, to replace "htab".
	(entry_hash, entry_compare, hash_init): Remove functions.
	(hash_ins): Use di-set functions, rather than ones from the hash module.

	touch: remove support for --file=REF_FILE option
	* src/touch.c (main): Remove support for the deprecated, long-named

	That option was undocumented with the arrival of --reference, in
	the 1995-10-29 commit, 8b92864e1d.  Since the 2009-02-09 commit,
	ed85df444a, use of --file has elicited a warning.  Not only was
	this code due for removal, but the long-name-use-detecting code
	was buggy in that it would use a stale or uninitialized "long_idx",
	as reported by Robin H. Johnson in http://bugs.gentoo.org/322421.

	truncate: improve handling of non regular files
	Previously we copied `dd` and suppressed error messages
	when truncating neither regular files or shared mem objects.
	This was valid for `dd`, as truncation is ancillary to copying
	it may also do, but for `truncate` we should display all errors.
	Also we used the st_size from non regular files which is undefined,
	so we display an error when the user tries this.

	* src/truncate (do_truncate):  Error when referencing the size
	of non regular files or non shared memory objects.  Display all
	errors returned by ftruncate().
	(main): Error when referencing the size of non regular files or

	sort: add a --debug option to highlight key extents
	* src/sort (usage): Add description for --debug.
	(write_bytes): Pass a line structure so it can subsequently
	be passed to compare to highlight the keys when in debug mode.
	Also transform TAB and NUL characters written to stdout so
	that the highlighting in debug mode aligns correctly.
	(human_numcompare): Pass an "endptr" so we can record the extent
	of the number matched.
	(general_numcompare): Likewise.
	(find_unit_order): Likewise.
	(getmonth): Likewise.
	(numcompare): Likewise.  Note we reuse find_unit_order() for this,
	which is a good enough approximation, and means we don't need to
	change the strnumcmp() interface.
	(check_mixed_SI_IEC): Return whether iec_present, so that can be
	used to set the "endptr" in find_unit_order.  Also make the key
	parameter optional, which will be the case from numcompare().
	(count_tabs): A new function to determine how much to adjust
	the mbswidth() values by (TABs don't have a width).
	(mark_key): A new function to output the key highlighting to stdout.
	(debug_key): A new function to determine the offset and width
	of the key highlighting.
	(key_compare): Pass the show_debug parameter so the key highlighting
	is only displayed when explicitly called.  For each key type, set
	the length (lena) and whether leading blanks are auto skipped (skipb)
	which are then used by debug_key() to highlight the portion of the
	key used in the comparison.
	(compare): Pass the show_debug parameter so the key highlighting
	is only displayed when explicitly called.  Call debug_key() to
	highlight the last resort comparison.
	(check): Output highlighting for disorder line to stdout.
	(main): Process the --debug option and make it mutually exlusive
	with the -o option as I don't see it useful there, even potentially
	harmful if someone left a --debug in by mistake when updating a file.
	Also restricting debug output to stdout, simplifies the logic
	for dealing with temporary files.
	* doc/coreutils.texi (sort invocation): Describe the --debug option,
	and reference it from the --key description.
	* tests/misc/sort-debug-keys: A new test for highlighting keys.

	sort: fix parsing of end field in obsolescent key formats
	This regression was introduced in commit 224a69b5, 2009-02-24,
	"sort: Fix two bugs with determining the end of field".
	The specific regression being that we include 1 field too many when
	an end field is specified using obsolescent key syntax (+POS -POS).

	* src/sort.c (struct keyfield): Clarify the description of the eword
	member, as suggested by Alan Curry.

	tests: avoid spurious failure of ls/color-norm test
	* tests/ls/color-norm: Use the "time" output by `ls -l`
	to check normal style.  Previously we used the size from `ls -s`,

	cp: treat selinux warnings consistently
	* src/copy.c (copy_reg): Suppress SELinux ENOTSUP warnings consistently
	between the destination being present or not.  Previously we did
	not suppress ENOTSUP messages when the destination was present.
	(copy_internal): Use the same ENOTSUP supression method as
	copy_reg() even though the issue was not seen in this case.
	* tests/cp/cp-a-selinux: Add a test case for the issue and
	group the other test cases in the file more coherently.
	* tests/cp/cp-mv-enotsup-xattr: Do the same check for xattr
	warnings, even though they did not have the issue.

	doc: clarify when cp and mv output xattr warnings
	The 2010-03-26 commit, 4c38625e, "doc: fix info on cp --preserve..."

	xattr warnings.

	* src/copy.h: Update and clarify the comments for reduce_diagnostics
	and require_preserve_{xattr,context}.
	* doc/coreutils.texi (cp invocation): Update the -a and

	maint: mbsalign: fix an edge case where we truncate too much
	* gl/lib/mbsalign.c (mbsalign): Ensure the temporary destination buffer

	in the presence of single byte non printable chars.
	* gl/tests/test-mbsalign.c (main): Add a test to trigger the issue.

	maint: update the mbsalign module
	* gl/lib/mbsalign.c (mbsalign):  Support the MBA_UNIBYTE_FALLBACK
	flag which reverts to unibyte mode if one can't allocate memory
	or if there are invalid multibyte characters present.
	Note memory is no longer dynamically allocated in unibyte mode so
	one can assume that mbsalign() will not return an error if this
	flag is present.  Don't calculate twice, the number of spaces,
	when centering.  Suppress a signed/unsigned comparison warning.
	(ambsalign): A new wrapper function to dynamically allocate
	the minimum memory required to hold the aligned string.

2010-03-16  Pádraig Brady  <P@draigBrady.com>

	timeout: add the --kill-after option
	Based on a report from Kim Hansen who wanted to
	send a KILL signal to the monitored command
	when `timeout` itself received a termination signal.
	Rather than changing such a signal into a KILL,
	we provide the more general mechanism of sending
	the KILL after the specified grace period.

	* src/timeout.c (cleanup): If a non zero kill delay
	is specified, (re)set the alarm to that delay, after
	which a KILL signal will be sent to the process group.
	(usage): Mention the new option.  Separate the description
	of DURATION since it's now specified in 2 places.
	Clarify that the duration is an integer.
	(parse_duration): A new function refactored from main(),
	since this logic is now called for two parameters.
	(main): Parse the -k option.
	* doc/coreutils.texi (timeout invocation): Describe the
	new --kill-after option and use @display rather than
	@table to show the duration suffixes.  Clarify that
	a duration of 0 disables the associated timeout.
	* tests/misc/timeout-parameters: Check invalid --kill-after.
	* tests/misc/timeout: Check a valid --kill-after works.
	* NEWS: Mention the new feature.

2010-03-04  Joey Degges  <jdegges@gmail.com>

	sort: inform the system about our input access pattern
	Tell the system that we'll access input sequentially,
	so that we more efficiently process uncached files in a few cases:

	Reading from faster flash devices. E.g. 21 MB/s key:
	  NORMAL     31.6s (26.8 user)
	  SEQUENTIAL 27.7s
	  WILLNEED   27.7s

	Processing in parallel with readahead when using a small 1M buffer:
	  NORMAL     24.7s (21.1 user)
	  SEQUENTIAL 22.7s
	  WILLNEED   25.6s

	A small benefit when merging:
	  NORMAL     25.0s (16.9 user)
	  SEQUENTIAL 24.6s (16.6 user)
	  WILLNEED   38.4s (13.1 user)

	Note WILLNEED is presented above for comparison to show it
	has some unwanted characteristics due to its synchronous
	prepopulation of the cache. It has a good benefit on a
	mechanical disk @ 80MB/s and a multicore system with
	competing processes:
	  NORMAL     14.73s
	  SEQUENTIAL 10.95s
	  WILLNEED   05.22s
	However the scheduling differences causing this result
	are probably best explicitly managed using `nice` etc.

	* m4/jm-macros.m4 (coreutils_MACROS): check for posix_fadvise().
	* src/sort.c (fadvise_input): A new function to apply
	the POSIX_FADV_SEQUENTIAL hint to an input stream.
	(stream_open): Call the above function for all input streams.

2010-03-04  Jim Meyering  <meyering@redhat.com>

	tests: don't let the LANGUAGE envvar perturb tests
	* tests/envvar-check (vars): Add LANGUAGE to the list of envvars
	to unset.  At least in glibc (as an extension to POSIX), its value
	actually trumps LC_ALL:

	  $ LC_ALL=es_ES LANGUAGE=fr_FR.UTF-8 /bin/cat no-such
	  /bin/cat: no-such: Aucun fichier ou dossier de ce type

	but only when the default locale is not C:

	  $ LC_ALL=C LANGUAGE=fr_FR.UTF-8 /bin/cat no-such
	  /bin/cat: no-such: No such file or directory

	Prompted by a report from Mads Kiilerich.

2010-03-01  Pádraig Brady  <P@draigBrady.com>

	sort: fix issues with month sorting in some locales
	* src/sort.c (char fold_toupper[]): Change to unsigned
	so as the correct comparisons are made in getmonth().
	This fixes unibyte locales where abbreviated months
	have characters that are > 0x7F, but it also works for
	multibyte locales with the caveat that multibyte characters
	are matched case sensitively.
	With this change, the following example sorts correctly:
	  $ echo -e "1 márta\n2 Feabhra" | LANG=ga_IE.utf8 sort -k2,2M
	  2 Feabhra
	  1 márta
	* src/sort.c (inittables): Since we ignore blanks around months
	in the input, don't include them when they're present in the locale.
	With this change, the following example sorts correctly:
	  $ echo -e "1 2月\n2 1月" | LANG=ja_JP.utf8 sort -k2,2M
	  2 1月
	  1 2月
	* tests/misc/sort-month: A new test to exercise the above cases.

	* NEWS: Mention the fix.

	The regression was introduced with commit 483297d5, 28-02-2009,
	"ls --color no longer outputs unnecessary escape sequences".

	* src/ls.c (set_normal_color): A new function to output the

	(print_current_files): Output NORMAL before printing long format info.
	(print_file_name_and_frills): Output NORMAL before printing file name.
	(print_color_indicator): Reset the attributes before a file name with

	(print_name_with_quoting): Ensure attributes are reset after printing
	the file name if NORMAL attributes were output.
	* tests/ls/color-norm: A new test for NORMAL and FILE combinations.
	* tests/Makefile.am: Reference the new test.
	* NEWS: Mention the fix.

	join: make -t '' operate on the whole line
	Previously passing an empty parameter to -t would
	raise an error, but now it means to treat each line
	as a single field for matching.  This matches the
	default operation of `sort` which is usually used
	in conjunction with join.

	* src/join.c (main): Set the field delimiter to '\n' if
	an empty parameter is passed to -t.
	(usage): Mention the operation of -t ''.
	* tests/misc/join: Add 2 new tests, for the existing -t '\0'
	and the new -t '' functionality.

	* NEWS: Mention the change in behavior.

	join: add --header option to always output the first line
	This essentially allows one to use --check-order with headings.
	Note join without --check-order will already handle the common case
	where headings do match in each file, however using --check-order will fail
	often when the header sorts after the first line of data.

	Note also that this will join header lines from each file even if
	they don't match, with headings from the first file being used.

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

	id: handle systems without getgroups support
	If getgroups failed with ENOSYS, mgetgroups would unnecessarily
	fail, and that provoked id into freeing an uninitialized pointer.
	Meanwhile, we were not using xalloc_die properly.  Both issues

	build: fix link failure on cygwin
	Cygwin 1.5 has a broken sleep, and the gnulib tests dragged in
	rpl_sleep which then caused a link failure because it wasn't in
	libcoreutils.a.  We could solve it by using the gnulib sleep module.
	However, sleep and usleep may interact poorly with SIGALRM, and they
	have less granularity; so it is better to adopt a policy that if we
	must sleep, prefer xnanosleep.

	* src/sort.c (pipe_fork): Use xnanosleep, to avoid the need for
	rpl_sleep on cygwin, and to reduce granularity.
	(MAX_FORK_TRIES_COMPRESS, MAX_FORK_TRIES_DECOMPRESS): Increase,

	With commit 0cc04241, we took the alternate approach of untainting the

	ls: fix capability coloring
	Capability checking was incorrectly done on just the base name
	rather than on the whole path.  Consequently there could be both
	false positives and negatives when coloring files with capabilities.
	Also capability checking was not done at all in certain cases for
	non executable files.  Note passing absolute rather than relative
	names to cap_get_file() reduces the has_capability() overhead
	from around 33% to 30%.  I.E. ls --color is now around 3% faster.

	* src/ls.c (struct fileinfo): Add a has_capability member.
	(print_color_indicator): Refactor to pass just a fileinfo pointer
	and a flag to say if we're dealing with a symlink target.
	(print_name_with_quoting): Likewise.

	build: consistently use freopen-safer
	cat, head, ptx, shuf, tac, tail, tee, tr, and uniq used freopen

	In glibc 2.11 and gnulib, gen_tempname added a parameter

	nice, nohup, su: detect write failure to stderr
	These programs can print non-fatal diagnostics to stderr prior to
	exec'ing a subsidiary program.  However, if we thought the situation
	warranted a diagnostic, we insist that the diagnostic be printed
	without error, rather than blindly exec, as it may be a security risk.

	For an example, try 'nice -n -1 nice 2>/dev/full'.  Failure to raise
	priority (by lowering niceness) is not fatal, but failure to inform
	the user about failure to change priority is dangerous.

	build: don't let environment settings perturb build
	Setting the envvars, LIB_FDATASYNC, LIB_XATTR or LIB_CRYPT
	could cause a configure-time and/or build-time malfunction.
	Typically, a configure-time function-in-library test is performed
	via code like this:

	  LIB_VAR=
	  AC_SUBST([LIB_VAR])
	  prefix_saved_LIBS=$LIBS
	    AC_SEARCH_LIBS([FUNC], [LIB_NAME],
	                   [test "$ac_cv_search_FUNC" = "none required" ||
	                    LIB_VAR=$ac_cv_search_FUNC])
	  LIBS=$prefix_saved_LIBS

	However, in each of the files affected by this change, the LIB_VAR=
	initialization was omitted.  Thus, when set in the environment, its
	value would propagate into generated Makefiles when FUNC is not found
	in LIB_NAME.
	* m4/jm-macros.m4 (coreutils_MACROS): Initialize AC_SUBST'd var

	a now dead process, but before the pid check, is not output.  We use
	the POSIX guarantee that read() and write() are serialized wrt each
	other even in separate processes, to assume full file consistency
	after exit() and so poll for new data _after_ the writer has exited.
	This also allows us to not redundantly _wait_ for new data if the
	process is dead.

	* tests/tail2/assert: This reverts commit be853120, 25-08-2009,
	"tests: tail-2/assert: avoid risk of race condition"
	kill -0 doesn't send a signal and so will only confirm that the
	background process was forked, which we know already because
	we have its pid.

	tests: address a race condition in misc/cat-buf
	* tests/misc/cat-buf: Increase the delay between writes
	to decrease the chance that dd will read both at once.
	Since the test is inherently racy, print a warning via

2009-09-07  Jim Meyering  <meyering@redhat.com>

	tail: syntax-only: use "false", rather than equivalent, 0
	* src/tail.c (record_open_fd): Initialize "->ignore" to false, not 0.

	tail: ignore -f for piped-stdin, as POSIX requires
	* src/tail.c (main): Tailing a pipe "forever" is not useful,
	and POSIX specifies that tail ignore the -f when there is no
	file argument and stdin is a FIFO or pipe.  So we do that.
	In addition, GNU tail excludes "-" arguments from the list of files
	to tail forever, when the associated file descriptor is connected
	to a FIFO or pipe.  Before this change, ":|tail -f" would hang.
	Reported by Ren Yang and Ulrich Drepper.

	tests: tail-2/flush-initial should not rely on stdbuf
	* tests/tail-2/flush-initial: stdbuf is not built on all systems.
	In any case it's redundant since stdout will automatically be buffered
	since we're redirecting to file. So just call tail without using stdbuf.

2009-09-07  Jim Meyering  <meyering@redhat.com>

	tail: don't give up on inotify mode for an already-ignored "-"

	tests: misc/cat-buf: clean up syntax
	* tests/misc/cat-buf: Don't suppress dd's stderr.
	Remove useless quotes.

	tests: ls/color-clear-to-eol: append NL to accommodate old sed

	Reported by Pádraig Brady.

	tests: tail-2/infloop-1: avoid rare test failure on a busy system
	* tests/tail-2/infloop-1: Sleep 3 seconds, not 1, but in increments

	"make -j9 check" on a quad-core system.
	Correct comment.

	* tests/misc/ls-misc: Set umask to 022.  A umask setting permitting

	build: fix libcap configure flag handling
	* m4/jm-macros.m4 (coreutils_MACROS): The code to handle configure-time
	enabling or disabling of libcap support was broken.  It would treat any
	libcap configure option as --disable-libcap because it doesn't check
	$enableval at all.  This change makes sure we do the sane thing:
	  --disable-libcap -> disable and don't run any tests
	  --enable-libcap -> run tests and fail if not found
	  default -> run tests and warn if not found

	tests: simplify and fix a race in 2 tail --follow tests
	* tests/tail-2/pid: Use the timeout command to determine process
	longevity, rather than querying /proc/$pid/status.
	The latter was racy in any case when inotify is used, as then
	tail wakes up periodically even for unchanging files therefore
	causing the check for "S (sleeping)" state to fail intermittently.

	It would do that by relying on readdir's dirent.d_ino values, while
	most readdir implementations return the inode number of the underlying,
	inaccessible directory.  Thus, it is not consistent with what you'd
	get when applying stat to the same entry.  This bug led to surprising
	results like "ls -i" and "ls -i --color" printing different numbers (ls
	must usually "stat" a file to colorize its name).  This change makes it
	so that on offending systems, ls must stat non-command-line-arguments
	for which otherwise it would be able to use "for free" dirent.d_ino
	values.  Regardless of this change, ls is already required to stat every
	command-line argument.  Note: versions of GNU ls prior to coreutils-6.0
	did not perform the invalid optimization, and hence always printed
	correct inode numbers.  Thus, for the sake of correctness, ls -i is
	forgoing the readdir optimization, for any kernel (including linux!)
	with POSIX-nonconforming readdir.  Note that currently, only Cygwin has
	been agile enough to conform.

	* src/ls.c (RELIABLE_D_INO): Define.
	(print_dir): Use it.
	For plenty of discussion, see this long thread:
	http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/14020

	cp: work around linux kernel bug: short-read != EOF on /proc
	Remove the optimization that avoided up to 50% of cp's read syscalls.
	Do not assume that a short read on a regular file indicates EOF.
	When reading from a file in /proc on linux [at least 2.6.9 - 2.6.29]
	into a 4k-byte buffer or larger, a short read does not
	always indicate EOF.  For example, "cp /proc/slabinfo /tmp"
	copies only 4068 of the total 7493 bytes.  This optimization
	(25719a33154f0c62ea9881f0c79ae312dd4cec7a, Improve performance a bit
	by optimizing away; 2005-11-24) appears to have been worth less than
	a 2% speed-up (and usually much less), so the impact of removing it
	is negligible.

	* src/copy.c (copy_reg): Don't exit the loop early.
	* tests/cp/proc-short-read: New test, lightly based on a suggestion
	from Mike Frysinger, to exercise this fix.

	ls: fix alignment when month names have varying widths
	Reported by Samuel Thibault and Stéphane Raimbault, as the glibc fr_FR
	locale has recently changed to use the official but variable width
	abbreviated month names. Other glibc locales also have variable widths.
	http://sourceware.org/ml/libc-locales/2008-q1/msg00035.html

	* NEWS: Mention the fix

	* gl/lib/mbsalign.h: Ditto

	* bootstrap.conf: Reference the new module
	* src/ls.c (abmon_init): New function, precompute the abbreviated
	months aligned left in a minimum width column <= 5 screen cells.
	(align_nstrftime): New function, replace the first %b in the
	format specification to strftime with the precomputed month string.
	Note using the cached month strings speeds up `ls -lU` by around 17%
	on glibc-2.7-2 on linux at least.  Also if we implement this function
	using heap storage rather than automatic storage, and use snprintf
	instead of strcpy, ls will slow down by 2% and 1% respectively
	(i.e. a net gain of 14% rather than 17%).

	sort: handle fd exhaustion better when merging
	This is an alternative to my 9 March patch labeled "Silently lower
	nmerge; don't (sometimes incorrectly) range-check"
	<http://lists.gnu.org/archive/html/bug-coreutils/2009-03/msg00070.html>.
	It differs by not using 'dup' to probe for extra file descriptors;
	instead, it simply calls 'open' (and 'pipe') to open files and pipes,
	until one of these calls fails due to file descriptor exhaustion; it
	then backs off by 1, does a merge with the files that it has opened,
	and then retries with the (now-smaller) number of files.

	This patch requires quite a few more changes to the source code than
	the earlier patch, but it is in some sense "better" because it doesn't
	need to call "dup" ahead of time in order to decide whether "open" or
	"pipe" will fail.  Also, it's more robust in the case where "open" or
	"pipe" fails with errno==EMFILE because some system-wide limit is
	exhausted.

	* src/sort.c (create_temp_file): New arg SURVIVE_FD_EXHAUSTION.
	(stream_open): New function, containing guts of xfopen.
	(xfopen): Use it.
	(pipe_fork): Set errno on failure.
	(maybe_create_temp): New function, containing guts of create_temp.
	(create_temp): Use it.
	(open_temp): Distinguish failures due to file descriptor exhaustion
	from other failures, and on fd exhaustion return a notice to caller
	rather than dying.  Don't test execlp's return value; when it returns,
	it *always* returns -1.
	(open_input_files): New function.
	(mergefps): New arg FPS. It's now the caller's responsibility to open
	the input and output files.  All callers changed.
	(mergefiles): New function.
	(avoid_trashing_input, merge): Handle the case where a single merge
	can't merge as much as we wanted due to file descriptor exhaustion, by
	merging as much as we can and then retrying.
	* tests/Makefile.am (TESTS): Add misc/sort-continue.
	* tests/misc/sort-continue: New file.
	* THANKS: Add Glen Lenker and Matt Pham who coauthored this patch.

	cp: diagnose invalid "cp -rl dir dir" right away, once again
	Running "mkdir dir; cp -rl dir dir" would create dir/dir/dir/...
	rather than diagnosing the "copy-into-self" failure.

	The easy fix would have been to revert this part of the change
	[3ece0355 2008-11-09 cp: use far less memory in some cases]
	that introduced the bug:

	-         remember_copied (dst_name, dst_sb.st_ino, dst_sb.st_dev);
	+         if (!x->hard_link)
	+           remember_copied (dst_name, dst_sb.st_ino, dst_sb.st_dev);

	However, that would have induced the failure of the new cp/link-heap
	test, due to the added memory pressure of recording 10k dev/ino pairs.
	And besides, I liked that improvement and wanted to keep it.

	Now that it's obvious recording the just-created-directory dev/ino
	needn't depend on the setting of hard_link, I realized it is necessary
	to record the pair only for the first directory created for each
	source command-line argument.

	I made that change, then noticed the new test, cp -rl a d d, would pass
	when run once, yet output the into-self diagnostic twice.  Also note
	the side effect: it creates d/a and d/d.  However, running that same
	command a second time, now with the modified directory, would fail.

	That turned out to be due to the fact that although the first into-self
	failure was detected in copy_dir, that function would continue copying
	other entries regardless -- and that would make it fail (eventually)
	with the unwanted recursion.

	* src/copy.c (copy_internal): This function needed an indicator of
	whether, for a give command line argument, it had already created its
	first directory.  If so, no more need to record dev/ino pairs.  If this
	is the first, then do record its pair.  Hence, the new parameter.
	(copy_dir, copy): Update callers.
	(copy_dir): Upon any into-self failure, break out of the loop.
	* tests/cp/into-self: Test for the above.

	ls: clean up after wrapped+colored file names with clear-to-EOL
	This change addresses a relatively unusual case: ls --color, with
	a highlighted name being printed initially in the last row of a
	terminal emulator (possibly followed by other lines of output) such
	that it is wrapped onto the following line, as the terminal emulator
	scrolls the output.  That would cause the entire following line to
	be highlighted, even if the name happened to use only one position.
	The least-invasive patch would have made colorized output larger for
	all uses.  The approach taken below is more invasive, but limits the
	increase in overhead to only those lines that are expected to wrap.
	* src/ls.c (enum indicator_no): Add C_CLR_TO_EOL.
	(indicator_name): Add "cl".
	(color_indicator): Add default escape codes for "cl".
	(print_long_format): Propagate width to print_name_with_quoting.

	Reported by Alexander V. Lukyanov.  See thread for details:
	http://thread.gmane.org/gmane.linux.kernel/740021/focus=14824
	Thanks to Jan Engelhardt for helping me reproduce the problem.

	Demonstrate with this in an 80-column xterm:
	  seq 200 # to start in the "bottom" row
	  touch zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz.foo
	  env LS_COLORS='*.foo=0;31;42' ls -og --color=always

	Before the fix, you'd see something like this:
	(where the file name is printed in red on a green background,
	and each "=" denotes a space on a green background)
	...
	  -rw-r--r--  1       0 Feb  5 11:31 zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz\

	pathchk: avoid -Wsign-compare warnings
	* src/pathchk.c: Compare pathconf limits to _signed_ MAX constants,
	as pathconf returns signed values.

	pr: avoid -Wsign-compare warnings
	* src/pr.c: Use unsigned variables in unsigned comparisons.

	shred: avoid -Wsign-compare warnings
	* src/shred.c: Use already assigned signed variable sizeof_r,
	rather than the unsigned sizeof(r). Don't use signed integer
	overflow check that contemporary compilers may remove anyway.

	simplify mgetgroups() and avoid -Wsign-compare warnings
	* gl/lib/mgetgroups.c: Avoid -Wsign-compare warning by using unsigned
	types for the parameters of the new function realloc_groupbuf().
	mgetgroups() was refactored to use this function rather than
	explicitly allocating and copying from automatic storage itself.
	* src/group-list.c: Use int rather than size_t as variable is
	used in signed comparisons.
	* src/id.c: ditto.

	rather than using arbitrary 2^63
	* tests/misc/split-fail: Check --lines --bytes and --line-bytes
	options limits on all platforms. Note getlimits obviates the
	need to use expr to check if 32 bit integers are supported,
	which I think was invalid anyway as expr now supports bignum?

	Then I updated serial numbers and copyright dates manually.
	Also, I manually added two pairs of quotes in boottime.m4.

	bootstrap: don't use cmp's -s option when reading from a pipe
	GNU cmp exits without reading all input when given the -s option,

	so that all input is read.

	* src/timeout.c (apply_time_suffix): Change input parameter from
	unsigned int to unsigned long, which is the type of the variable it's

	getlimits: A new utility for use in coreutils' tests
	* src/getlimits.c: A utility to print platform dependent
	limits in a format suitable for use in shell scripts.
	* src/Makefile.am: Add getlimits to list of utilities
	to build but not install. Also add it to the list linked
	with libiconv
	* po/POTFILES.in: Add getlimits to translation list.

	dd: avoid unnecessary memory copies
	* src/dd.c (scanargs): When not otherwise required (e.g. for
	conversion), use two-buffer mode only when the input and output
	buffer sizes differ.  Before, some of the most basic invocations of
	dd, e.g., dd < in > out, would unnecessarily use separate buffers
	and perform memory copies between them.

2008-11-20  Jim Meyering  <meyering@redhat.com>

	cp: use far less memory in some cases
	cp --link was "remembering" many name,dev,inode triples unnecessarily.
	cp was doing the same, even without --link, for every directory in the
	source hierarchy, while it can do its job with entries merely for the
	command-line arguments.  Prompted by a report from Patrick Shoenfeld.
	Details <http://bugs.debian.org/412688>.
	* src/copy.c (copy_internal): Refrain from remembering
	name,dev,inode for most files, when invoked via cp --link.
	Record an infloop-avoidance triple for each directory specified
	on the command line, not for each directory in the source tree.
	Don't record a dir-triple when x->hard_link is set.
	* NEWS (Buf fixes): Mention it.
	* tests/cp/link-heap: New file.  Test for cp's lowered memory usage.
	* tests/Makefile.am (TESTS): Add link-heap.

	tests: add a test of cp --preserve=links
	* tests/cp/link-preserve: Add a case and comments.

	cp: remove unused code
	* src/cp-hash.c (remember_created): Remove unused function.
	Remove thus-obviated headers: <stdio.h>, "quote.h", "error.h".

	would be detected as a known problem and cause the test to be skipped.

	factor: avoid compilation failure without libgmp
	* src/factor.c (debug) [!HAVE_GMP]: Define.
	Reported by Bob Proulx.

2008-10-25  Paul Eggert  <eggert@CS.UCLA.EDU>

	factor: remove --bignum and --no-bignum options
	Here's a patch to remove the --bignum and --no-bignum options from
	'factor'.  The case for removing --bignum isn't as strong as that for
	'expr', but still, it seems to me that these options are not needed and
	complicate the documentation unnecessarily.

	* doc/coreutils.texi (factor invocation): Remove --bignum, --no-bignum.
	* src/factor.c (algorithm, ALGORITHM_CHOICE, USE_BIGNUM, NO_USE_BIGNUM):
	Remove; all uses removed.
	(extract_factors_multi): Remove, replacing with....
	(print_factors_multi): New function, with signature similar to that
	of new signature of print_factors_single.
	(print_factors_single): Migrate checking code to caller.
	(print_factors): Use GMP if it's available; don't bother asking user.
	Improve accuracy of check for "large" numbers.

	* src/seq.c: Don't include <math.h>, <float.h>.
	(abs_rel_diff): Remove.
	(print_numbers): Test for equality, not for an epsilonish value.
	This reverts 4827dd27b0c655a685947aaa01426a5ecba179f3, aka
	v6.10-185-g4827dd2, which broke 'seq' on the x86; for example, it
	causes "seq 9223372036854775807 9223372036854775808" to incorrectly
	output 3 numbers instead of 2.  It's better to punish obsolescent
	hosts that have incorrectly-working floating-point than to punish
	correctly-working hosts.
	* tests/misc/seq: Use 0.9000000000000, rather than
	0.90000000000000000000, to avoid tickling a bug in Solaris 8 strtold,
	which converts "0.9" and "0.9000000000000" correctly, but incorrectly
	converts "0.90000000000000000000" to a smaller value.

	Since 84f6abfe00b4ab533145623638b417a2221f9c75, ls --color would check

2008-10-17  Jim Meyering  <meyering@redhat.com>

	maint: avoid warning in ls.c
	* src/ls.c (has_capability) [!HAVE_CAP]: Add unused attribute.

	maint: avoid warnings due to attribute warn_unused_result
	Now that a (void) cast no longer suffices to ignore warnings from gcc
	about uses of functions marked with the warn_unused_result attribute,
	we need an alternative.  For the record, here's one of the ignorable
	warnings: "copy.c:233: warning: ignoring return value of 'fchown',
	declared with attribute warn_unused_result"
	* bootstrap.conf (gnulib_modules): Import ignore-value.
	* src/copy.c: Include "ignore-value.h".
	(set_owner): Use ignore_value in place of "(void)" casts,
	to ignore lchown and fchown failures.
	* src/cp.c (re_protect): Likewise, to ignore lchown failure.

2008-10-16  Jim Meyering  <meyering@redhat.com>

	build: when po-check fails, say why and suggest a fix
	* maint.mk (po-check): Before, when this check failed, it just
	spat out a diff mentioning two temporary files.  Now, it tells
	you what's wrong and suggests a fix with a patch using the name
	of the affected file (rather than temporary file names) in the
	diff output.

2008-10-16  Eric Blake  <ebb9@byu.net>

	csplit: prefer sigaction over signal
	* bootstrap.conf (gnulib_modules): Import sigaction.
	* src/csplit.c (sigprocmask, siginterrupt) [SA_NOCLDSTOP]: Delete
	workarounds.
	(interrupt_handler, main): Drop use of signal.  Rely on sigaction
	to block fatal signal during cleanup, and to restore it to default
	in case of nested signals.

2008-10-15  Pádraig Brady  <P@draigBrady.com>

	tests: add option processing tests for 'expr'
	* tests/misc/expr: Add tests for various combinations
	of options where the first part of the expression
	could be confused with an option.

2008-10-15  Paul Eggert  <eggert@cs.ucla.edu>

	expr: remove --bignum and --no-bignum options
	* doc/coreutils.texi (expr invocation): Remove the --bignum and
	--no-bignum options.  They weren't really needed, and they broke
	longstanding (albeit nonportable) scripts.
	* src/expr.c: Don't include <assert.h>.  Include "inttostr.h",
	"long-options.h", "verify.h".  Check at compile-time that
	size_t fits in unsigned long int, as the code assumes this in
	several places.
	(HAVE_GMP): Define to 0 if not defined, for convenience.
	(mpz_t, mpz_clear, mpz_init_set_ui, mpz_init_set_str, mpz_add):
	(mpz_sub, mpz_mul, mpz_tdiv_q, mpz_tdiv_r, mpz_get_str, mpz_sgn):
	(mpz_fits_ulong_p, mpz_get_ui, mpz_out_str):
	Supply substitutes when !HAVE_GMP, which work well enough for
	expr's purposes.
	(mp_integer): Remove.  All integers are gmp, if gmp is available.
	(struct valinfo): Remove 'z' member; no longer needed.  The 'i'
	member is always of type mpz_t.
	(enum arithmetic_mode, MP_NEVER, MP_ALWAYS, MP_AUTO, mode):
	Remove; no longer needed.
	(usage): Remove documentation of --bignum and --no-bignum.
	(integer_overflow): Abort if error misbehaves, to pacify GCC.
	Restore old message on arithmetic overflow, to be conservative.
	(die): Omit exit_status parameter; not needed (is always EXPR_FAILURE).
	(string_too_long, USE_BIGNUM, NO_USE_BIGNUM, long_options):
	Remove; no longer needed.
	(main): Don't use getopt_long; this breaks old nonportable scripts.
	(int_value): Arg is unsigned, in case we have strings whose length
	exceeds LONG_MAX (!).
	(int_value, freev, printv, null, tostring, toarith):
	(eval6, eval4, eval3):
	Always use mpz_ functions, to simplify the code.
	(substr_value): Remove; no longer needed.
	(getsize): Simplify the API: one arg rather than 3.  Don't assume
	unsigned long int fits in size_t.
	(promote, domult, dodivide, doadd): Remove; no longer needed.
	* tests/misc/expr: Don't use --bignum to test for bignum support.
	Instead, use big numbers to test this.

2008-10-15  Jim Meyering  <meyering@redhat.com>

	expr: don't interpret argv[0] as an operand
	* src/expr.c (main): Given a first argument like -22 (negative, with
	two or more digits), expr would decrement optind to 0 and then attempt
	to evaluate argv[0].

	doc: cp, mv: remove mention of deprecated --reply= option
	* doc/coreutils.texi (cp invocation, mv invocation): Don't mention it.

	Reported by Greg Metcalfe in <http://bugzilla.redhat.com/446294>.

2008-10-12  Jim Meyering  <meyering@redhat.com>

	doc: reorder tsort/ptx nodes so body and menu ordering are consistent
	* doc/coreutils.texi (tsort invocation, tsort background): Move these
	nodes "down", so that they follow the ptx nodes, thus matching the
	alphabetized order in the menu.
	(tsort background): Make this a subsection.
	Suggested by Karl Berry.

	tests: move check-misc targets from src/Makefile.am to maint.mk
	* src/Makefile.am (check): Remove check-misc.
	(check-misc): Remove target.
	* maint.mk (sc_prohibit_stat_st_blocks): New target.
	(sc_prohibit_S_IS_definition): New target.
	* Makefile.am (EXTRA_DIST): Add .x-sc_prohibit_stat_st_blocks.
	* .x-sc_prohibit_stat_st_blocks: New file.
	Andreas Schwab reported that "make check" could fail to detect
	violation of the no-S_IS*-definition policy.

	tests: df: avoid test failure when using mawk
	* tests/df/total-awk: Rewrite to use $PERL, not $AWK.
	mawk can't even count above 2^31.  Reported by Ed Avis.
	http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/14792/focus=14802
	* tests/df/total-verify: Rename from total-awk.
	* tests/Makefile.am (TESTS): Reflect renaming.

	rm -r: avoid O(n^2) performance for a directory with very many entries
	This enhancement works around a problem that is specific to at least

	supported in expr.
	* src/expr.c (enum valtype): Added mp_integer, signifying a GNU MP
	number.

	(main): parse these options with getopt_long instead of
	parse_long_options.

	intmax_t to signed long, since MP lacks functions for promoting an
	intmax_t to an arbitrary-precision quantity.

	the case where an argument to the 'index' expression is too long
	for a string offset to be represented.
	(int_value): With --bignum, create the value as mp_integer rather
	than plain integer.
	(substr_value): factored out of eval6; implements "substr".
	(freev): also destroy mp_integer values.  Check that no mp_integer
	values exist if --no-bignum was specified.
	(printv, null, tostring): support mp_integer.

	truncate: ignore whitespace in --size parameters
	Without this, `truncate -s '> -1' F` would truncate F to length 0,
	and `truncate -s " +1" F` would truncate F to 1 byte.  Now, the
	first elicits a diagnostic, and the second works properly.
	* src/truncate.c: Skip leading white space in the --size option

2008-06-27  Pádraig Brady  <P@draigBrady.com>

	truncate: Fix integer portability issues
	* src/truncate.c: Explicitly convert from off_t to intmax_t
	when printing numbers as they may be different types.
	Also don't mix size_t and off_t types in operations as
	the latter will be promoted to unsigned when these types
	are the same size.

	bootstrap.conf: don't list "open" specifically
	It is no longer necessary to list it specifically,
	now that several gnulib modules depend on the "open" module.
	This reverts commit 3ea1fe588e20f196cc9b9907d5943bd620c6b944.

	truncate: handle the case in which off_t != intmax_t
	* src/truncate.c (parse_len): Use a temporary of type intmax_t,

	tests: remove ugly /bin/sh wrapper around each perl-based test script
	* tests/check.mk (TESTS_ENVIRONMENT): Save and restore TMPDIR around
	envvar-check, so that the few scripts that require $TMPDIR don't fail.
	This is also good to let a user's default TMPDIR setting be used e.g.,

	FIXME: this is pretty ugly.  maybe undo it and find a better way.
	(TESTS_ENVIRONMENT): Invoke perl scripts with $(PERL), and use -T
	if the script requires that.  Otherwise, use $(SHELL).

	Fix old brokenness exposed by this change:

	being attached to a non-tty.
	* tests/misc/sort (3g, 3h, 3i): Likewise: add explicit empty input file.

	* tests/rm/fail-eperm: Now that this test is run from a temporary
	subdirectory, adjust the full name of the "rm" program we're going
	to run.

	Change #!/bin/sh to #!/usr/bin/perl, and factor out the few lines
	of boilerplate code to invoke perl.  Do not "require 5.00x";

	tests: allow to run Perl tests more cleanly

	Instead, limit the importing of gettext-related symbols

	Before, upon interrupt, directories would be left behind.
	* tests/CuTmpdir.pm: Remove temporary directory on interrupt.

	tests: reorder some tests in the long list
	* tests/Makefile.am (TESTS): Move some tests that use sleep

	* tests/Makefile.am (EXTRA_DIST): Remove its name.

	tests: cp/perm (usually not run) was failing on systems with SELinux
	* tests/cp/perm: Use stat to get the permission string, not ls.
	This test was run only when RUN_VERY_EXPENSIVE_TESTS=yes was set
	in the environment.  It would fail on SELinux-enable systems
	because ls-generated permission strings would not match, e.g.,
	"test _-rw-r--r--+ = _-rw-r--r--" would fail.

	id: do print the AFS-specific nameless group ID (called a PAG)
	In 6.11, we mistakenly suppressed the printing of certain group IDs,
	thinking they were useless AFS-specific artifacts.
	This change reverts that, so now they are printed once again.
	http://thread.gmane.org/gmane.org.fsf.announce/867/focus=13345
	This also reverts the bug-fix that applied solely to the new code
	used to avoid printing those IDs

	Revert "id bug fix: don't point to potentially clobbered static storage"
	This reverts commit f7d1c59c224f81a8bab5fa2afcaf815988f50467.
	Revert "Work around AFS bug: id and groups would print invalid group number."
	This reverts commit b7a836c0a3524cda8ef79c30c3fe7ea759ae4656.
	Revert "* src/c99-to-c89.diff: Accommodate a C99-ism in id.c."

	* tests/mkdir/perm: Use the function rather than sourcing the file.

	in tests/Makefile.am.

2008-04-20  Jim Meyering  <meyering@redhat.com>

	Revamp test-related Makefiles.
	One side-effect of this change is that "make check" now works even if
	you put "." early in your shell's search PATH (don't do that!).

	Remove all test-related Makefile.am files, except those generated
	by mk-script.  Instead, tests/Makefile.am now lists not only the
	tests directly under tests/, but also those in tests/*/ that are
	not generated by mk-script, e.g., cp/abuse, cp/acl, mv/i-1, etc.

	A lot of these changes are like this:

	-. $srcdir/../lang-default
	+. $top_srcdir/tests/lang-default

	-. $srcdir/../test-lib.sh
	+. $top_srcdir/tests/test-lib.sh

	* configure.ac (AC_CONFIG_FILES): Remove corresponding Makefiles.
	* tests/check.mk (vc_exe_in_TESTS): Relax syntax requirements.
	* tests/rwx-to-mode: Remove file.  Rewritten as...
	* tests/test-lib.sh (rwx_to_mode_): ...this new function.
	* tests/Makefile.am (EXTRA_DIST): Remove rwx-to-mode.
	(SUBDIRS): Remove each dir with a removed Makefile.am.
	(EXTRA_DIST): Add $(TESTS).
	(TESTS): Add over 300 entries.

2008-04-20  Jim Meyering  <meyering@redhat.com>

	* tests/misc/Makefile.am (built_programs): Remove.  Unused.

	Use "env" to invoke potential built-ins.

	rather than via an absolute name.
	* tests/touch/not-owner: Likewise for test.

2008-04-16  Jim Meyering  <meyering@redhat.com>

	tests: accommodate built-in mknod more cleanly
	* tests/mkdir/selinux: Undo most of previous change,
	bc22dbbf844f31ddaf2e68b167d0128a985d73ab, and instead
	invoke the command via "nice".  Using "exec" should be
	enough, but isn't with OpenBSD's PD KSH v5.2.14 99/07/13.2.
	Eric Blake suggested using nice.

	mknod --help: note that this command may be a shell built-in
	* src/mknod.c (usage): Print USAGE_BUILTIN_WARNING.
	Suggestion from Eric Blake.

	avoid "may be used uninitialized" warning from newer gcc
	* src/md5sum.c (digest_check) [lint]: Initialize local, "filename".

	tests: add a comment explaining the potential failure

	tests: avoid mkdir/selinux failure when mknod is a shell built-in

	This is required at least on Haiku and BeOS.
	* src/remove.c (write_protected_non_symlink): Return 1 for a write-
	protected non-symlink, 0 if we determine it's not, and -1 upon
	error (setting errno accordingly only in this final case).

	bootstrap: remove dangling *.[ch] symlinks from lib
	* bootstrap [dangling symlink removal]: Match *.[ch] files, too.
	Suggestion from Eric Blake.

	bootstrap: make find's -depth option be the first.
	* bootstrap [dangling symlink removal]: Move find's -depth
	option to precede all others, to avoid a warning.

	* bootstrap: Remove dangling symlinks from lib (aka $source_base), too.

	Avoid root-only SELinux-related test failures w/o mcstransd.
	When mcstransd is not running (i.e., after service mcstrans stop),
	"make check" as root would provoke two test failures.
	* tests/cp/cp-a-selinux: Use the context, root:object_r:tmp_t:s0,
	that works both with and without mcstransd.
	Thanks to Eric Paris for the tip and to Ondřej Vašík for alerting
	me to the problem.
	Reported by Robert Scheck in <http://bugzilla.redhat.com/436717>.

	root tests: Set NON_ROOT_USERNAME if not set already.

	couple of root-only tests that require a value for that envvar.

	texinfo formatting tweaks
	* coreutils.texi: Avoid some overfull hbox warnings.
	(Treating / specially): Use @file{/} rather than a bare /.

	printf doc: xref print(3) and libc's "Output Conversion Syntax" node
	* coreutils.texi (printf invocation): Add xref.
	Use "The GNU C Library Reference Manual" as the name of the 'libc'
	document consistently.
	* man/printf.x: Add See also: printf(3).
	Suggested by A. Costa in http://bugs.debian.org/465522

2008-03-31  Jim Meyering  <meyering@redhat.com>

	Emit "#line 1" right after the two 'read-only/GENERATED' lines.
	* bootstrap (cp_mark_as_generated): This preserves line numbering
	e.g., in assertions, which is important when correlating between
	coreutils test failures and the original files in gnulib/tests.
	Suggested by Eric Blake.

	* README-contribution-guidelines: Mention how to amend a commit.
	Suggestion from Pádraig Brady.

	Begin documenting contribution guidelines.
	* README-contribution-guidelines: New file.  For now, not distributed.

	"rm -r DIR" would mistakenly prompt about very long names
	* src/remove.c (write_protected_non_symlink): Return 0(-1) when
	euidaccess_stat pronounces a writable(not-writable) file, not -1(0).
	* tests/rm/deep-2: New file.  Test for the above-fixed bug.
	* tests/rm/Makefile.am (TESTS): Add deep-2.
	Discovered while reviewing this change:

	* tests/mkdir/selinux: Also accept ENOENT.
	Reported by Sven Joachim.

	tests: accept ENOTSUP message as well as the EINVAL one
	This test would fail on most non-Linux systems because the original
	expected an "Invalid argument" diagnostic, yet they all produced
	"Operation not supported".
	* tests/mkdir/selinux: Accept both strings.  Factor out duplication.

	portability: work around a "busybox sed" limitation
	* configure.ac: While every other sed tested supports usage like
	'/\(re\)/{s//\1/;...<NEWLINE>}', and POSIX appears to requires this,
	busybox's sed does not support it.  So duplicate the regexp:

	* NEWS: call this a "portability improvement" ;-)
	* src/c99-to-c89.diff: Adjust remove.c offsets.

2008-03-21  Ingo Weinhold  <ingo_weinhold@gmx.de>

	remove.c: Accommodate systems with negative errno values.
	* src/remove.c (cache_fstatat): Store errno value directly in
	the st_ino field, rather than trying to shoehorn it into st_size.
	This is required at least on BeOS and Haiku.

2008-03-21  Jim Meyering  <meyering@redhat.com>

	* src/seq.c (long_double_format): Add a comment.

2008-03-20  Jim Meyering  <meyering@redhat.com>

	* GNUmakefile: Update from gnulib.

	Remove today's automake kludge, altogether.  Fix properly.
	* man/Makefile.am: Use dist_man1_MANS instead of dist_man_MANS.
	Suggestion from Ralf Wildenhues.

	Add a check to detect this problem, in case it reappears.
	* maint.mk (my-distcheck): Run "make install", and then ensure
	that ls.1 is installed.

	Kludge to make automake generate install-man rules
	* man/Makefile.am (dist_man_MANS): Add a literal, rm.1.
	Without this, "make install" would not install man pages.
	However, with this kludge, the rm.1 man page is installed
	even when you configure with --enable-no-install-program=rm.

	Revert recent man/Makefile.am change.
	Revert 4b544e447eb78fd1f031a026a499f6aed177808a.
	* man/Makefile.am: That change was only a band-aid.  It solved
	the stated problem, but not a deeper one: that "make install"
	would no longer man pages.  Reported by Dmitry V. Levin.
	The latter problem arose in
	167b8025aca487de001da2448c1aebc2747bc1d3 with the removal of
	the sole literal from the definition of dist_man_MANS.  When
	automake perceives dist_man_MANS as empty, it no longer emits
	the install-man* rules.

2008-03-20  Eric Blake  <ebb9@byu.net>

	This restores code removed by dec8bb25bb6da2fe9fe6dd63c0fbbd593a0e94cb.
	Reported by Bob Proulx.

	Check for -- and remove -- some unnecessarily included header files.
	* Makefile.maint: Add checks for a handful of additional header files.
	* src/mktemp.c: Don't include "long-options.h".  Not used.
	* src/pr.c: Don't include "inttostr.h".  Not used.

	Remove more vestiges of CVS.
	* Makefile.maint (VC_LIST): Rename from CVS_LIST.
	(VC_LIST_EXCEPT): Rename from CVS_LIST_EXCEPT.

	mv: never unlink a destination file before calling rename
	While cp --preserve=links must unlink certain destination files,
	mv must never do that.
	* src/copy.c (copy_internal): Pull the '! x->move_mode' test "up",
	so it affects the entire condition, and not just DEREF_NEVER mode.
	Reported by James Ralston in <http://bugzilla.redhat.com/438076>.
	* tests/mv/atomic2: New file.  Test for the above fix.
	* tests/mv/Makefile.am (TESTS): Add atomic2.

	Autoconf will use this to override _autoreconf and to export PATH.
	(_autoreconf): Define.
	(_dummy): cd to $(srcdir) before removing autom4te.cache.

	* bootstrap: Sync from gnulib and remove part of a local kludge.

	* src/c99-to-c89.diff: Accommodate a C99-ism in id.c.

2008-03-05  ribalba  <geerd.dietger.hoffmann@gmail.com>

	Work around AFS bug: id and groups would print invalid group number.

2008-03-05  Jim Meyering  <meyering@redhat.com>

	Now that Makefile.maint is used in VPATH builds, too...
	* Makefile.maint (prev_version_file): Prefix with $(srcdir)/.
	(syntax-check-rules): Prefix $(ME) with $(srcdir)/.

	Avoid new "make distcheck" failure, now that VPATH has GNUmakefile.
	* GNUmakefile: Remove commands to create ".version".
	They were unnecessary, and caused creation of a newer .version
	file in a VPATH build, which in turn caused creation of updated
	man/*.1 files reflecting the newer time stamp on .version.
	Those *.1 files were not removed (since they're distributed), and
	the fact that they remained after "distclean" triggered the failure.

2008-03-04  Eric Blake  <ebb9@byu.net>

	Reinstate GNUmakefile patch, but with workaround for automake.
	* configure.ac (AC_CONFIG_LINKS): Use shell variable to bypass
	automake distclean rules.
	* Makefile.am (distclean-local): Clean GNUmakefile in VPATH builds,
	since we are bypassing automake.

2008-03-03  Eric Blake  <ebb9@byu.net>

	* configure.ac: The latter is only in post-2.61 autoconf.

	GNUmakefile build tweaks.
	* GNUmakefile: When Makefile is not present, make common targets depend
	on "all" in order to trigger nicer error message.
	* configure.ac: If autoconf is new enough, link GNUmakefile into VPATH
	builds.
	For more details, see

2008-03-02  Jim Meyering  <meyering@redhat.com>

	* tests/Makefile.am (built_programs): Remove unused definition.
	* src/Makefile.am (built_programs.list): Print a space-separated
	list of program names, not NL-separated, since all clients now
	expect a space-separated list.

	Don't exempt "groups" from write-failure test, now that it's a C program.

	Make copyright comments consistent.
	* src/mktemp.c: Update copyright to use newer form.

	Make first copyright lines consistent. Some did not end in ", Inc.".
	Due to that missing ", Inc" at end of line, emacs' copyright-updating
	code missed some opportunities.  This corrects most of those, and

	(free_prevline): new atexit function; frees items in prevline[].
	Use ARRAY_CARDINALITY, so include "argmatch.h" to get that.
	(main): Arrange for free_prevline to be called during exit.
	(get_line): Free prevline[which - 1] also, as that
	will have been allocated by dup_line.

2008-02-20  Jim Meyering  <meyering@redhat.com>

	Remove xdelta support, clean up distcheck process. * Makefile.maint (writable-files): Don't create $(release_archive_dir). (my-distcheck): Don't depend on prev-tgz. Remove xdelta-related variables and uses. (alpha beta major): Skip steps if $(release_archive_dir) doesn't exist.

	New variables check_input_order, seen_unpairable and

	and the second time with LS_COLORS set using the default settings
	produced by running dircolors.
	* tests/Coreutils.pm: See below.

	This required some changes:
	  - save and restore $ENV{LS_COLORS} for each individual test
	  that requires a specific value.
	  - Since this is the first test to call the run_tests command more
	  than once, it has exposed that that function erroneously modifies
	  the \@Tests array.  Fix that in tests/Coreutils.pm.

2008-02-17  Jim Meyering  <meyering@redhat.com>

	Adjust dircolors to match ls.c.

	time_t to struct timespec.

2008-02-14  Jim Meyering  <meyering@redhat.com>

	(id: Print user identity): Likewise for "id".
	* po/POTFILES.in: Add src/group-list.c and src/groups.c.
	* NEWS: mention this.
