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.

	maint: remove a misleading comment from shred.c
	* src/shred.c: Remove obsolete TODO comment.  The first two and the
	last item were done, adding --recursive (-r) is neither necessary
	nor appropriate, and I don't want to add --interactive.  I don't
	see a need for the others.  Prompted by comments from Amr Ali.

	ls: be responsive to interrupts when color-listing large directories
	Starting with commit adc30a83, when using --color, ls inhibited
	interrupts to avoid corrupting the state of an output terminal.
	However, for very large directories, that inhibition rendered ls
	uninterruptible for too long, including a potentially long period
	even before any output is generated.
	* src/ls.c: Two phases of processing are time-consuming enough that
	they can provoke this: the readdir loop and the printing loop.  The
	printing was supposed to be covered by a call to process_signals in
	(print_name_with_quoting): ... but that call was mistakenly guarded
	by a condition that might be false for many or even all files being
	processed.  Call process_signals unconditionally.
	(print_dir): Also call process_signals in the readdir loop.
	* NEWS (Bug fixes): Mention it.

	maint: don't assume GNU make \# syntax (fix previous)
	* src/Makefile.am (fs_normalize_perl_subst, fs-magic, fs-kernel-magic):
	Undo previous patch; it missed a \#.
	(fs_normalize_perl_subst): Use \043 rather than \#.
	\043 is portable to all ASCIIish platforms, whereas \# is portable
	only to platforms that are compatible with GNU make (and are
	incompatible with POSIX make).  Porting this to EBCDIC is left as
	an exercise for the reader....

	doc: fix list of GNU extension date formats
	I didn't check how long these were documented as GNU extensions,
	nor when they were added by POSIX; but since they are all part
	of POSIX 2008, we no longer need call them out as extensions.

	The next version of POSIX will standardize %s:
	http://austingroupbugs.net/view.php?id=169
	but as that is not out yet, I didn't change %s.

	* doc/coreutils.texi (Time conversion specifiers): %R and %z are

	tests: adjust PATH to generally include /sbin and /usr/sbin
	Commit 5eeaca94 added /sbin to the PATH for tests using mkfs. For other
	tests, e.g. tests/cp-fiemap-perf using filefrag, we need /usr/sbin also.
	Add both directories generally for the tests, "since many of us always
	augment our PATH with all of the sbin paths all of the time anyway" (Bob
	in http://lists.gnu.org/archive/html/coreutils/2011-11/msg00107.html).
	The previous commit is hereby obsolete.
	* tests/init.cfg (sanitize_path_): Add /sbin and /usr/sbin to PATH
	unless already included. Needed for tests using admin tools like mkfs
	and filefrag on systems where the user's environment does not have
	these directories in the PATH.

	build: update gnulib for syntax-check improvement
	Commit 5b3e538 proved useful enough to migrate to gnulib after

	* gnulib: Update to latest.

	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

	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.

	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
	an update to gnulib's manywarnings module: -Wformat-nonliteral,
	-Wunsuffixed-float-constants, -Wdouble-promotion.

	* bootstrap.conf (buildreq): Copy (with backup) coreutils-supplied
	git hooks into .git/hooks, to help keep commit logs normalized.

	maint: add rule to ensure that our commit hook copies are up to date
	* Makefile.am (check-git-hook-script-sync): New rule -- not used
	anywhere, because it depends on having very recent git.
	* scripts/git-hooks/pre-applypatch: New file.

	maint: sync pre-commit script with git's
	* scripts/git-hooks/pre-commit (allownonascii): Remove double quotes
	around $(...) construct, to make this file identical to git's
	sample hook script.

	build: update gnulib for fstatat cross-compile improvement

	maint: adjust the URL that will appear in the generated announcement
	* cfg.mk (url_dir_list): Use this http://ftp.gnu.org/gnu/$(PACKAGE)
	for the first link listed in the generated announcement.
	announce-gen now provides the faster mirror link automatically.

	ls: plug a per-argument leak
	Using ls -l on an SELinux-enabled system would leak one SELinux
	context string per non-empty-directory command-line argument.
	* src/ls.c (free_ent): New function, factored out of...
	(clear_files): ...here.  Use it.
	(extract_dirs_from_files): Call free_ent (f), rather than simply
	free (f->name).  The latter failed to free the possibly-malloc'd
	linkname and scontext members, and thus could leak one of those
	strings per command-line argument.
	* THANKS.in: Update.
	* NEWS (Bug fixes): Mention it.

	* tests/misc/sort-continue: Port to Fedora 15.
	Redirect with the shell command, not in a separate 'exec'.
	Without this patch, Fedora 15 x86-64 /bin/sh (i.e., Bash 4.2.10)
	complained about running out of file descriptors in the shell.

	* tests/ls/block-size: Make it executable.

	* src/system.h (emit_size_note): Reword for clarity.
	See discussion in Bug#9939.

	ls: -k no longer affects -l's file sizes
	This fixes an incompatibility with POSIX 2008 and with BSD.
	Problem reported by Abdallah Clark (Bug#9939)
	via Alan Curry (Bug#10016).
	* NEWS: Document this.
	* doc/coreutils.texi (General output formatting): Document the
	new -k behavior, and --kibibytes.
	* src/ls.c (file_human_output_opts): New static var.
	(long_options, usage): Add --kibibytes.
	(decode_switches, gobble_file, print_long_format):

2011-11-04  Jim Meyering  <meyering@redhat.com>

	build: do use fstatat and unlinkat modules, now that they're separate
	* bootstrap.conf (gnulib_modules): Add fstatat and unlinkat.

	build: update gnulib to pull in openat module separation changes
	No semantic change.

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

	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
	an infinite loop in rare circumstances.

	* 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.

2011-11-02  Jim Meyering  <meyering@redhat.com>

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

	maint: fix git-log typos when generating ChangeLog
	* gnulib: Update to latest, for new gitlog-to-changelog.
	* Makefile.am (gen-ChangeLog): Use its new --amend=F option.
	* build-aux/git-log-fix: New file, with ChangeLog fixes.

	stat: avoid compilation failure with gnulib's new alignof
	* src/stat.c: Include <stdalign.h>, not "alignof.h" for alignof use.

	scripts: reject references to long-form bug URLs
	* scripts/git-hooks/commit-msg: Require the normalized/shortened
	form of bugzilla.redhat.com and bugs.gnu.org bug URLs.

2011-11-01  Pádraig Brady  <P@draigBrady.com>

	doc: date: mention that the hardware clock might not be set

	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
	because date could not parse that particular format.  Now that
	it can, it's time to restore the documentation.
	* src/date.c (usage): Document it.
	* doc/coreutils.texi (Options for date): Reinstate documentation.
	Reported by Hubert Depesz Lubaczewski in http://bugs.gnu.org/7444.

	build: avoid bootstrap failure when using patch-2.5.8
	* gl/modules/tempname.diff: Regenerate to correct bogus offsets
	and adjust for 1-line offset.  Eric Blake reported that this
	patch failed to apply when using patch-2.5.8.
	Note that it applies fine using patch-2.6.1.

2011-10-25  Jim Meyering  <meyering@redhat.com>

	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
	definition would have provoked build failure on systems that use it,
	like FreeBSD.  Reported by Bruno Haible in
	http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/28739/focus=28795

	* 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

	tac: do not let failed allocation cause immediate exit
	* src/tac.c (temp_stream): Don't exit immediately upon failed heap

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,

	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.

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.

	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.

	bootstrap: use latest gnulib bootstrap, gettext
	* bootstrap: Sync from gnulib.  This removes an obsolescent
	gettext.m4 patch, along with some other changes that do not
	seem to affect coreutils.
	* bootstrap.conf (gnulib_modules): Use gettext, not gettext-h.
	Current gnulib gettext seems to work without needing special hacking.

	* src/copy.c (copy_internal): With --update (-u), this function would

	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

	* NEWS: Mention fix for Bug#9098.

	timeout: add regression test (Bug#9098)
	* tests/misc/timeout: Check that 'timeout' is not confused when
	starting off with a child.

2011-07-16  Paul Eggert  <eggert@cs.ucla.edu>

	timeout: treat seconds counts like 'sleep' does
	Treat fractions as a request to round up to the next representable
	value, and treat out-of-range values as maximal ones.  This is
	consistent with how "sleep" works.  And this way, "timeout
	999999999999999999d FOO" and "timeout 4.5 foo" are more likely to
	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,
	other than its name) should be moved to a library?
	(parse_duration): Return a maximal value on overflow.  Return
	unsigned int, not unsigned long.  Allow fractions, which round
	up to the next integer value.
	* tests/misc/timeout-parameters: Adjust tests to match new behavior.
	Add a very large number.

	Fix capiTalization in comments.

	Instead, only declare the fiemap_extents zero length array

	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

	tests: stat-free-color: accommodate stat of /selinux on rawhide
	* tests/ls/stat-free-color: This test recently began to fail on
	rawhide because dynamic library start-up code now stats "/selinux",
	making the total number of calls 2 rather than the prior 1.
	Create two more dangling symlinks, so that any erroneous stat-
	or lstat-calling code will get at least those three.

2011-06-01  Marek Polacek  <mpolacek@redhat.com>

	yes.c: do not use exit after error
	I think it would be better to exit through the error() and not
	to call the exit() after the error().  This way we can get rid of
	one function call (and curly brackets).

	* src/yes.c (main): Exit through the error(), remove exit() call
	after error().

2011-06-01  Jim Meyering  <meyering@redhat.com>

	tail: fix an inconsequential bug spotted by coverity
	* src/tail.c (start_bytes): Increase *READ_POS (not READ_POS)
	by the number of bytes read.  This is a real bug that happens
	to have no consequence in practice.  First, this code is exercised
	only when tailing-forever a non-regular file by bytes, and with a
	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.

2011-05-26  Jim Meyering  <meyering@redhat.com>

	build: --enable-gcc-warnings: enable -Wstrict-overflow in src/
	* configure.ac (WARN_CFLAGS): Don't turn off -Wstrict-overflow.
	(GNULIB_WARN_CFLAGS): Remove -Wstrict-overflow from the list of
	warning options used in lib/.
	Normally I find that -Wstrict-overflow produces too many false
	positives, but considering that it warns of the bug reported in
	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/dircolors.c (main): Reorder operations to avoid the risk of

	* 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.

	* src/split.c (lines_chunk_split): Don't use ignore_error() which

	(ofile_open): Likewise. Add a comment to clarify that
	filters aren't restarted under file descriptor pressure.

	split: diagnose when --filter is used with a chunk number
	* src/split.c (main): Exit with a diagnostic if --filter
	is specified along with a specific chunk number.
	* test/split/filter: Ensure this combination fails.

	split: exit when we can no longer write to a --filter
	* src/split.c (bytes_split): Stop reading when we
	can no longer write to a child process.
	(lines_rr): Likewise.
	(lines_bytes_split): No change is made here since
	input is bounded by the original file size.
	* test/split/filter: Add test cases.

	split: return success even if a --filter exits
	src/split.c (main): Don't unblock SIGPIPE before cleanup,
	as then any pending signals will be sent and cause
	the main split process to exit with a non zero status (141).
	* test/split/filter: Add a test for this case.

	split: fix an edge case where -n l/... creates an extra file
	* src/split.c (lines_bytes_chunk): Handle the edge case

	maint: accommodate gnulib's newer tight_scope rule
	* cfg.mk: Include via "-include", to accommodate new tight-scope rule.
	(sc_check-AUTHORS): Change the name of the rule in src/Makefile.am

	this file is included into the sub-make's context.
	* src/Makefile.am (_sc_check-AUTHORS): Rename from sc_check-AUTHORS.
	* gnulib: Update to latest.

	doc: make README-hacking slightly more generic
	* README-hacking: Remove a reference to "coreutils".

	touch: placate static analyzers: no NULL-deref is possible
	* src/touch.c (main): Avoid even the hint of possibility that
	we'd dereference NULL upon localtime failure.  Coverity reported
	the potential, but it appears not to be possible, since posixtime
	rejects any time for which the subsequent localtime would return NULL.

	tests: fix typo in tac-continue
	* 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
	and creating a full partition just for this test case.

	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.

	build: avoid bootstrap failure when $GZIP is set
	Running "GZIP=-9 ./bootstrap" would fail right away, because the

	* tests/cp/sparse-fiemap: When this test was run as root on an ext3
	file system, (ext3 had known problems), it would trickily create and
	mount a loopback ext4 file system and use that instead.  However, due
	to a bug in 2.6.39-rc1..rc3, this loopback test (when run in another
	loopback FS) exposed a bug with 1k-blocksize ext4 whereby non-NUL
	data would be read from a hole.  For details, see this:

	* NEWS (Changes in behavior): Document this.  At first I labeled this

	you could end up installing files full of zeros instead of the expected

	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: preserve-gid: don't chown temporary PATH dir to a nameless UID

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.

	Also we convert the empty extent to a hole only when SPARSE_ALWAYS
	so that the source and dest have the same allocation.  This will
	be improved soon, when we use fallocate() to do the allocation.
	* tests/cp/fiemap-empty: A new test for efficiency and correctness
	of copying empty extents.

	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

	touch: update to latest gnulib to fix Solaris 10 touch segfault
	* gnulib: Update to latest, to address http://debbugs.gnu.org/8230.
	When built on Solaris 9 and run on Solaris 10, touch would segfault.
	Reported by Ben Walton.
	* bootstrap: Update from gnulib.
	* tests/init.sh: Likewise.
	* NEWS (Bug fixes): Mention this.

	sort: spawn fewer threads for small inputs
	* src/sort.c (SUBTHREAD_LINES_HEURISTIC): Do not spawn a new thread
	for every 4 lines.  Increase this from 4 to 128K.  128K lines seems
	appropriate for a 5-year-old dual-core laptop, but it is too low for
	some common combinations of short lines and/or newer systems.
	* NEWS (Bug fixes): Mention it.

	copy: merge similar extents before processing
	* src/extent-scan.c (extent_scan_read):  Merge adjacent extents
	that vary only in size, so that we may process them more efficiently.
	This will be especially useful when we introduce fallocate()
	so that we don't reproduce fragmentation in the destination.

	* tests/dd/nocache: Don't assume stdin is a pipe

	dd: add a flag to discard cached data
	* src/dd.c (FFS_MASK): A new macro (Find First Set) refactored
	from the following enum as it's now used twice.
	(usage): Mention the new 'nocache' flag.
	(cache_round): A new function to help ignore requests
	to drop cache, that are less than page_size.
	(invalidate_cache): A new function to call posix_fadvise()
	with the appropriate offset and length.  Note we don't
	use fdadvise() so we can detect errors when count=0.
	(dd_copy): Call invalidate_cache() for the portions read.

	* src/dd.c (usage): Move 'sync' up with other data transformation
	options.  Having it alongside 'fsync' and 'fdatasync' is
	particularly confusing.  Also the double line description of
	the 'sync' option, serves as a visual break from the "flag"
	type options that follow.
	* doc/coreutils.texi (dd invocation):  Apply the same grouping
	as above, by splitting the "conv=" table in two.

	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

	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,

	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".

	uptime: omit unnecessary #if
	* src/uptime.c (print_uptime): Omit unnecessary "#if defined

	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: 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.

	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.

	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

	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.

	tests: cp/fiemap: exercise previously-failing parts

	* 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

	fiemap copy: avoid a performance hit due to very small buffer
	* src/copy.c (extent_copy): Don't let what should have been a

	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

	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,

	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.

	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.

	Report ioctl failure if it's the 2nd or subsequent call.

	tests: relax the root-tests cross-check

	from linux's include/linux/fiemap.h, with minor formatting changes.
	* src/copy.c (copy_reg): Now, when `cp' is invoked with --sparse=[WHEN],

	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

	of the old THANKS file is now a template, THANKS.in.
	We'll still have to manually list the names of people who report

	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.

	(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.
	* tests/misc/sort-merge-fdlimit: Test for the bug.

2010-12-14  Jim Meyering  <meyering@redhat.com>

	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/sort-compress-proc: New file, to test for the
	bugs fixed above.

2010-12-13  Paul Eggert  <eggert@cs.ucla.edu>

	tests: typo fix
	* tests/misc/sort-stale-thread-mem: Fix typo in comment.

2010-12-13  Jim Meyering  <meyering@redhat.com>

	tests: tweak basic-1 to use warn_ rather than literal "exit 77"
	* tests/install/basic-1 (just_built_dd): Use warn_, rather than
	cat and exit 77.

	tests: mark new test as very expensive
	* tests/misc/sort-stale-thread-mem: Don't initialize fail=0 here;
	that is done in init.sh.  This avoids a syntax-check failure.
	Invoke "Exit $fail" at end, too.
	Mark as a very expensive test.

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

	tests: test for access to stale thread memory
	* tests/misc/sort-stale-thread-mem: New tests.
	* tests/Makefile.am (TESTS): Add it.

2010-12-11  Jim Meyering  <meyering@redhat.com>

	tests: avoid FP failure when run under valgrind
	* 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.

2010-12-09  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/misc/sort-unique-segv: New file.

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>

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

	maint: update the valgrind support script
	* README-valgrind: Include the "noinst" programs in

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

	(set_suffix_length): New function to auto increase suffix length
	to handle a specified number of files.
	(create): New function.  Refactored from cwrite() and ofile_open().
	(bytes_split): Add max_files argument to support byte chunking.
	(lines_chunk_split): New function.  Split file into chunks of lines.
	(bytes_chunk_extract): New function.  Extract a chunk of file.
	(of_info): New struct.  Used by functions lines_rr and ofile_open
	to keep track of file descriptors associated with output files.
	(ofile_open): New function.  Shuffle file descriptors when there
	are more output files than available file descriptors.
	(lines_rr): New function to distribute lines round-robin to files.
	(chunk_parse): New function.  Parses K/N syntax.
	* tests/misc/split-bchunk: New test for byte chunking.

	* 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.

	* .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.

	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.

	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.

	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 *

	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.

	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

	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.
	* tests/Makefile.am: Reference the new test.
	* NEWS: Mention the fixes.

2010-09-21  Paul Eggert  <eggert@cs.ucla.edu>

	build: update gnulib submodule to latest

	sort: destroy spin locks portably
	* src/sort.c (sortlines, sort): Use pthread_spin_destroy when a
	spin lock is no longer used.  This isn't needed on GNU/Linux or
	Solaris, but POSIX says it may free up resources on some platforms.

2010-09-20  Pádraig Brady  <P@draigBrady.com>

	tests: fix a printf portability issue
	* tests/misc/sort-debug-keys: Don't depend on
	printf supporting \xhh format, which isn't supported
	by dash for example.  Also change from double quoted
	strings to single quoted, when we don't need any
	variable interpolation.

	tests: fix an erroneous stat failure with bind mounts
	* tests/misc/stat-mount: Don't try to correlate the
	mount points output by df and stat, as they're similar,
	but sometimes different in the presence of bind mounts.
	* doc/coretuils.texi (stat invocation): Clarify the
	bind mount difference between stat and df.

2010-09-18  Jim Meyering  <meyering@redhat.com>

	tests: sync tests/init.sh from gnulib
	* tests/init.sh: Update from gnulib.

	build: use gnulib's new termios module
	With it, we can remove the two sole tests of HAVE_TERMIOS_H.
	* bootstrap.conf (gnulib_modules): Add termios.
	* src/ls.c: Don't test HAVE_TERMIOS_H.
	* src/stty.c: Likewise.
	* m4/jm-macros.m4 (gl_CHECK_ALL_TYPES): Remove configure-time
	test for termios.h.

	maint: don't use obsolete gnulib modules
	* bootstrap.conf (gnulib_modules): Use calloc-gnu, malloc-gnu
	and realloc-gnu modules, rather than calloc, malloc and realloc.
	The shorter-named modules are now deprecated.
	(obsolete_gnulib_modules): Remove.
	(gnulib_modules): Remove raise, strbprk; they're obsolete, too.
	Move strtod, strtol here, from obsolete_gnulib_modules.

	tests: make various timeouts more robust
	* tests/init.cfg (retry_delay_): Describe
	the backoff method used.
	* tests/ls/readdir-mountpoint-inode: Add a timeout

	tac: suppress technically unneeded "free"
	* src/tac.c (main): Guard final free with #ifdef lint.
	Suggested by Paul Eggert.

2010-09-01  Pádraig Brady  <P@draigBrady.com>

	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.
	* tests/misc/tac (double-free): New test, to exercise this.

	* src/df.c: Use the new find-mount-point module.
	* src/stat.c (print_stat): Handle the new %m format.
	(find_bind_mount): A new function to

	(out_mount_mount): Print the bind mount for a file, or else
	the standard mount point given by the find-mount-point module.
	(usage): Document the %m format directive.
	* src/Makefile.am: Reference the refactored find-mount-point.c
	* po/POTFILES.in: Add find_mount_point.c to the translation list
	* doc/coreutils.texi (stat invocation): Document %m,
	and how it may differ from the mount point that df outputs.
	* test/misc/stat-mount: A new test to correlate mount points
	output from df and stat.
	* tests/Makefile.am: Reference the new test.
	* NEWS: Mention the new feature
	* THANKS: Add the author

2010-08-27  Eric Blake  <eblake@redhat.com>

2010-08-26  Pádraig Brady  <P@draigBrady.com>

	df: always print the device name for bind mounted files
	* src/df (show_point): Remove the optimization for comparing
	the specified path with the device name, as this produces
	inconsistent results in the presence of bind mounts.  For bind
	mounts, the device name is populated with the bind mount target.
	* NEWS: Mention the change in behavior.

2010-08-11  Paul Eggert  <eggert@cs.ucla.edu>

	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
	xrealloc, since the old buffer contents need not be preserved.
	Also, don't fail if the guessed-sized malloc fails.  Suggested by
	Bruno Haible.

2010-08-10  Eric Blake  <eblake@redhat.com>

2010-08-09  Dan Hipschman  <dsh@linux.ucla.edu>

	ls: fix a test failure that should have been skipped
	* tests/ls/readdir-mountpoint-inode: Check to see if skip_test_ is
	called in a helper function via $() instead of mistakenly failing.
	* THANKS: Update.

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):

	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.

	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.

	* src/sort.c (random_md5_state): New static var.
	(random_md5_state_init): New function, to initialize random_md5_state.
	(random_state, randread_source): Remove.
	(cmp_hashes): Use random_md5_state rather than random_state.
	Break ties using memcmp, not by getting more randomness.
	If MD5 collisions turn into a problem in practice, we should
	simply use a better checksum.
	(main): If -R is given, call random_md5_state_init rather than
	going single-threaded.

2010-07-17  Paul R. Eggert  <eggert@cs.ucla.edu>

	randread: don't require -lrt
	Programs like 'sort' were linking to -lrt in order to get
	clock_gettime, but this was misguided: it wasted considerable
	resources while gaining at most 10 bits of entropy.  Almost nobody
	needs the entropy, and there are better ways to get much better
	entropy for people who do need it.
	* gl/lib/rand-isaac.c (isaac_seed): Include <sys/time.h> not
	"gethrxtime.h".
	(isaac_seed): Use gettimeofday rather than gethrxtime.
	* gl/modules/randread (Depends-on): Depend on gettimeofday
	and not gethrxtime.
	* src/Makefile.am (mktemp_LDADD, shred_LDADD, shuf_LDADD, sort_LDADD):
	(tac_LDADD): Omit $(LIB_GETHRXTIME); no longer needed.

	* tests/misc/sort-unique: New file.

	sort: fix a bug with sort -u and xmemcoll0, and tune keycompare
	* src/sort.c (keycompare): Use xmemcoll0, as it avoids
	a couple of stores.
	(write_bytes): Leave the buffer the way we found it,
	as it might be used again for a later comparison,
	if -u is used.

2010-07-15  Pádraig Brady  <P@draigBrady.com>

	sort: fix a bug when sorting unterminated lines
	* src/sort.c (fillbuf): The previous commit incorrectly

2010-07-15  Chen Guo  <chenguo4@yahoo.com>

	sort: speed up default full line sorting
	Don't write NUL after the comparison buffers on each compare,

	* src/sort.c: (fillbuf): Delimit input items with NUL.
	(write_bytes): Restore the item delimiter char which was

	* src/Makefile.am (printf_LDADD, seq_LDADD, sleep_LDADD, sort_LDADD):
	(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

	(Bug fixes): Move to the start.
	(Changes in behavior): Add the item about the du mem usage change
	from the "New features" section.

	maint: heap.c: simplify dynamic allocations
	* gl/lib/heap.c (heap_alloc): Use the fact that the xalloc
	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

	* bootstrap.conf: Add heap, pthread.
	* coreutils.texi (sort): Describe the new --parallel option.
	* gl/lib/heap.c: New file. Very basic heap implementation.
	* gl/lib/heap.h: New file.

	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

	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.

	ls: use the POSIX date style when the locale does not specify one
	Previously we defaulted to "long-iso" format in locales without
	specific format translations, like the en_* locales for example.

	tests: fail rather than infloop in tail's inotify-rotate test
	* tests/tail-2/inotify-rotate: Switch to new init.sh-based framework.
	(grep_timeout): New function.
	Use it in place of open-coded loops that might infloop.
	This was prompted by my encountering an inexplicable, and so far
	unreproducible, infloop in the code that was waiting for "b" to
	appear in "out".

	tests: move most helper functions from test-lib.sh to new init.cfg
	From there, they will be used by both test-lib.sh (as we phase it out)
	and the newer init.sh, to which all tests will migrate.

	In upstream releases this option has always been a no-op.  It was

	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

	(mark_key): A new function to output the key highlighting to stdout.
	(debug_key): A new function to determine the offset and width

	the length (lena) and whether leading blanks are auto skipped (skipb)
	which are then used by debug_key() to highlight the portion of the

	(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

	Necessary for cygwin.  Technically, this patch is not correct,

	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.
	(main): When processing obsolescent format key specifications,
	normalize eword to a zero based count when no specific end char is given
	for an end field. This matches what's done when keys are specified with -k.
	* tests/misc/sort: Add a few more tests for the obsolescent key formats,
	with test 07i being the particular failure addressed by this change.
	* THANKS: Add Alan Curry who precisely identified the issue.
	* NEWS: Mention the fix.

	timeout: add the --kill-after option
	Based on a report from Kim Hansen who wanted to

	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.

	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.

	  $ 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:

	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

	ls: fix a regression by honoring NORMAL attributes again
	Output the NORMAL attribute before non file name text.
	This attribute will continue into file names that would
	not otherwise be colored unless FILE is also set.
	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
	NORMAL attribute sequence if it's enabled.
	(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

	These checks were not being run as distcheck-hook targets
	are only supported in the top-level Makefile.  Instead
	these tests are now run during a syntax-check.

2010-02-01  Pádraig Brady  <P@draigBrady.com>

	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.
	* doc/coreutils.texi (join invocation): Mention that
	join -t '' always operates on the whole line, while
	join -t '\0' usually does.
	* NEWS: Mention the change in behavior.

2010-02-01  Assaf Gordon  <assafgordon@gmail.com>

	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.
	(join): Join the header lines unconditionally.
	* tests/misc/join: Add 5 new tests.

2010-02-01  Pádraig Brady  <P@draigBrady.com>

	maint: fix an inconsequential memory leak in join
	* src/join.c (join): Refactor the code that checks for misorder
	at the tail of the files.  The most significant change here is
	that freeline() is called thus silencing a valgrind warning about
	a definite but inconsequential memory leak.
	(freeline): Make more general by doing nothing when passed NULL,
	and setting freed pointers to NULL.

	maint: use $(CONFIG_INCLUDE) rather than the hardcoding lib/config.h
	* tests/check.mk (TESTS_ENVIRONMENT): Use the generated CONFIG_INCLUDE
	variable.  Note $(abs_builddir)/$(CONFIG_HEADER) also currently works,
	but $(CONFIG_HEADER) is deprecated and may not be generated in future.
	$(CONFIG_INCLUDE) was made available by gnulib in commit, 22970f8a,
	"syntax-check: detect incorrect boolean macro values in config.h"

	Enabled when coreutils is configured with --with-tty-group.
	Based on a patch written by Piotr Gackiewicz.  Details at
	http://bugzilla.redhat.com/454261

	* src/who.c (is_tty_writable): A new function returning true if a TTY

	tests: work around spurious test failure with OpenBSD4.5's /bin/sh
	* tests/ls/infloop: OpenBSD4.5's /bin/sh would mistakenly include

	* tests/misc/sort-version: Don't use <<- and indented here-doc contents.

	  sh: <stdin>[4]: here document `x' unclosed

	build: update gnulib submodule to latest

	doc: mention two tail -F bug fixes in NEWS
	* NEWS (Bug fixes): Two tail -F fixes.

	tail: test for a bug in inotify-enabled tail -F
	tail -F a b would stop tracking additions to b after "mv a b".
	* tests/tail-2/F-vs-rename: New file.
	* tests/Makefile.am (TESTS): Add it.

2009-12-30  Giuseppe Scrivano  <gscrivano@gnu.org>

	tail -F: don't stop following the target of a rename
	This fixes a bug whereby tail -F would fail to track changes
	to a file that was a target of a rename, and when the source of
	the rename was another tailed file.

	* src/tail.c (tail_forever_inotify): Ensure the wd is not already
	present in the hash table before trying to add it.  When a new watch
	descriptor is added to the `wd_to_name' hash table, check that it is
	not already present.  If it is present then remove the previous element.

2009-12-30  Pádraig Brady  <P@draigBrady.com>

	maint: improve the info about $PATH in README-prereq
	* README-prereq: It wasn't obvious that the $PATH should

2009-12-29  Jim Meyering  <meyering@redhat.com>

	tail: add another test to exercise abort-inducing flaw in tail -F
	* tests/tail-2/inotify-hash-abuse2: New test, based on a reproducer
	by Rob Wortman.
	* tests/Makefile.am (TESTS): Add it.

	tail: add a test to exercise abort-inducing flaw in tail -F
	* tests/tail-2/inotify-hash-abuse: New file, derived from

	Improved by: Pádraig Brady.

2009-12-29  Giuseppe Scrivano  <gscrivano@gnu.org>

	tail: remove `fdspec' from the hash table before changing its key
	* src/tail.c (tail_forever_inotify): Avoid modifying fdspec->wd while
	it is in the wd_to_name hash table.  Once it is removed, it can be
	added using the new `wd' as key for the hash table.  This fixes the
	abort-inducing bug reported by Rob Wortman in
	http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/19372

2009-12-29  Jim Meyering  <meyering@redhat.com>

	maint: quiet "make" in doc/
	* doc/Makefile.am (constants.texi): Add a use of AM_V_GEN.

	tail: rename an internal variable
	* src/tail.c (tail_forever_inotify): s/wd_table/wd_to_name/

	tail: avoid read-beyond-end-of-buffer error
	* src/tail.c (tail_forever_inotify): Do not use f[i] in a context
	where i may be larger than the largest valid index.  In the final
	"if" clause in which we'd remove an inotify watch, we might have
	used f[n_files].  Use fspec instead, since it is guaranteed to
	be defined.

2009-12-25  Jim Meyering  <meyering@redhat.com>

	maint: tail: avoid in-function #if directives

	(any_remote_file): Rename from any_remote_files.

2009-12-25  Pádraig Brady  <P@draigBrady.com>

	refers to a remote file.
	(tail_forever_inotify): Add some comments.
	(tail_file): Record if a file is remote when initially opened.
	(main): Disable inotify if any remote files specified.
	Also document the caveat about remounted files not
	being noticed by inotify.
	* NEWS: Mention the fix.

	wc: line-buffer the printed counts
	* src/wc.c (main): Set stdout to line buffered mode
	to ensure parallel running instances don't intersperse
	their output.  This adds 6.5% to the run time in the worst case
	of many zero length files, but has neglible impact for
	standard sized files.
	* tests/misc/wc-parallel: New test for atomic output.
	* tests/Makefile.am: Reference it.
	* NEWS: Mention the fix
	This is similar to commit 710fe413, 20-10-2009,
	"md5sum, sha*sum, sum: line-buffer the printed checksums"

	* NEWS: Mention the fix.

2009-12-20  Jim Meyering  <meyering@redhat.com>

	build: correct coreutils-specific distcheck rules
	* dist-check.mk (built_programs): Use $(bin_PROGRAMS), not $(PROGRAMS).
	Otherwise, my-instcheck would fail due to non-installation of e.g.,
	the noinst_PROGRAMS, setuidgid and getlimits.
	(taint-distcheck): Correct the grep command that checks for libtool
	traces in configure.

	maint: don't include the strverscmp gnulib module
	* bootstrap.conf (gnulib_modules): Remove the strverscmp module
	which is not used since commit e505736f, on 03-10-2008,
	"ls and sort: use filevercmp instead of strverscmp"

	doc: enhance and reference info about version comparison
	* doc/coreutils.texi (sort invocation): Reference the additional
	info about filevercmp rather than the unused strverscmp.
	(Details about version sort): Add some examples that are not

	* src/ls.c: Change a comment referencing the now unused strverscmp.

	rm: fix --one-file-system regression due to fts conversion
	* src/remove.c (rm_fts): Fix incorrect comparison of

2009-12-14  Jim Meyering  <meyering@redhat.com>

	maint: improve dist-check.mk rules
	* dist-check.mk (null_AM_MAKEFLAGS): Remove LIBTOOL.  Adding it was
	erroneous, since it is required when building from a distribution
	tarball of a libtool-using project.  Reported by Ralf Wildenhues.
	(my-distcheck): Reorganize to use a subshell and set -e, so that
	failures propagate "out".  Without this change, setting LIBTOOL=false
	would cause a failure that would then be ignored, probably due to a
	problem in $(install-transform-check).

2009-12-14  Thiago Farina  <tfransosi@gmail.com>

	base64: use *_OPTION_DESCRIPTION macros instead of hard-coded strings
	* src/base64 (usage): Use HELP_OPTION_DESCRIPTION and
	VERSION_OPTION_DESCRIPTION macros, not literal strings.

2009-12-13  Jim Meyering  <meyering@redhat.com>

	tests: unpack xz-compressed tarballs when possible, not always *.gz
	* dist-check.mk: Unpack compressed tarball using xz when possible,
	since that's faster.

	maint: make dist-check.mk more easily shared
	* dist-check.mk (built_programs): More generic, but still assumes src/.
	Don't set GZIP in environment when untarring.
	(my-distcheck): Use $(DIST_ARCHIVES), rather than assuming that
	there is always a .tar.gz file.

	nohup: if fd_repoen fails (redirecting stdin), report it
	* src/nohup.c (main): Don't ignore fd_reopen failure.

	tests: make the taint-distcheck rule easier to share with other projects
	* dist-check.mk (taint-distcheck): Skip this test in a project
	that uses libtool.

	stat: recognize "sockfs" file system type, ...
	... now that its magic number appears in <linux/magic.h>.
	* src/stat.c (human_fstype) [S_MAGIC_SOCKFS]: Add case.

	maint: move definitions from maint.mk to dist-check.mk
	* dist-check.mk (null_AM_MAKEFLAGS): Define here, not in maint.mk.

	* tests/check.mk (CU_TEST_NAME): Better test names.

	tail: don't call fstat on an uninitialized FD
	This bug showed up via valgrind as a "Conditional jump or move
	depends on uninitialized value(s)" error.
	* src/tail.c (ignore_fifo_and_pipe): New function.
	(main): Use it only when tailing forever.
	The code to compute n_viable and mark some F[i] as ignored would call
	isapipe on an uninitialized file descriptor.  But n_viable and those
	.ignored marks are useful/used only when tailing forever.  This bug

	sort: fix failure if sort's parent has ignored SIGCHLD
	* src/sort.c (main): Reset the SIGCHLD handler to the default

	* tests/misc/sort-compress: Set the CHLD handler in a subshell
	to SIG_IGN to ensure the sort command resets it to SIG_DFL.
	* NEWS: Mention the fix.

	timeout: fix failure if timeout's parent has ignored SIGCHLD
	* src/timeout.c (main): Reset the SIGCHLD handler to the default
	as otherwise wait() could return -1 and set errno to ECHILD.
	This condition was ignored until commit 0b1dcf33, on 31-08-2009,
	"timeout: defensive handling of all wait() errors"
	but subsequently timeout would run the command correctly
	but then fail with an error message.
	* tests/misc/timeout: In a subshell set the CHLD handler to

	Otherwise, running "make distcheck" could leave an empty /tmp/coreutils
	directory behind.
	(tp): Simplify, now that it's always in the build-dir.
	(taint-distcheck): Set HOME earlier, in case $(MAKE) misbehaves.
	(my-instcheck, coreutils-path-check): Add diagnostics, so it's easier
	to diagnose when each runs.
	(coreutils-path-check): Run configure with --quiet, to reduce output.
	Inspired by Ralf Wildenhues' report of /tmp/coreutils being left behind.

	difference.  Skip such mount points.  Reported by Sergei Steshenko
	in http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/19142

2009-12-06  Pádraig Brady  <P@draigBrady.com>

	tests: don't run tail-2/inotify-race by default
	* tests/tail-2/inotify-race: Note the caveats of the test.
	I.E. the intermittent skips and the gdb hang reported

	is skipped as it may be due to multiple reasons.  Mark
	the test as very expensive so that it's not normally run.

	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
	are better solved in gnulib, by introducing xgetgroups; this
	patch uses the new interface.

	Regression introduced by commit 6a31fd8d7.

	* gnulib: Update, for mgetgroups improvments.
	* src/id.c (print_full_info): Adjust caller to die on allocation
	failure, and no longer worry about ENOSYS.
	* src/group-list.c (print_group_list): Likewise.
	* src/setuidgid.c (main): Likewise.

	rm: fix empty-name bug introduced with conversion to use fts
	While "rm ''" would properly fail, "rm F1 '' F2" would fail

	This bug was introduced on 2009-07-12, via commit 4f73ecaf,
	"rm: rewrite to use fts".

	Assert that the bit flags were not the cause of failure.
	* po/POTFILES.in: Remove xfts.c.
	* THANKS: Update.

	bootstrap: fix handling of various perl --version formats
	* bootstrap (get_version): Don't use perl's $] special

	use perl's x.yyyzzz version format.  Instead make the regular
	expression more general to support version formats from older
	perl-5.005_002 (5.5.2) and perl-5.11 which has other numbers

	Counterpart to commit 8fe40b84bd8, since test-link.c uses rename,

2009-11-24  Eric Blake  <ebb9@byu.net>

	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,
	to account for reduction in granularity.
	* src/tail.c (tail_file): Use xnanosleep in debug code.
	* cfg.mk (sc_prohibit_sleep): New rule.

	tests: avoid spurious failures due to insecure directory in PATH
	These tests perform no PATH search, and used to simply delete PATH from

	where cygwin.dll must be resolvable via PATH when starting a sub-shell.
	With commit 0cc04241, we took the alternate approach of untainting the
	incoming $ENV{PATH}, but that fails when it contains an other-writable
	directory.  Instead, now we hard code it to '/bin:/usr/bin'.

	This has the side effect of making it so that these programs
	no longer segfault when subjected to execve abuse.
	Before this change, these commands would make "true" segfault:
	  printf '%s\n' '#include <unistd.h>' 'int main(int c, char**v)' \
	    '{ execve (v[1], 0, 0); }' > k.c && gcc k.c && ./a.out $PWD/true
	Now it succeeds.  Reported by Tetsuo Handa and Bart Van Assche
	via Ondřej Vašík in http://bugzilla.redhat.com/537684.

	tail -F can fail to track a file after it's been rotated
	Tailing forever and by-name (--follow=name, -F), tail would
	sometimes fail to follow a file that had been removed via rename.
	If you can't apply this patch and have tail 7.6 or newer, you can
	work around the bug via the undocumented --disable-inotify option.
	* src/tail.c (tail_forever_inotify): When tailing by name (-F),
	do not un-watch a file upon receipt of the IN_MOVE_SELF event.

	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.

	nice, nohup, su: detect write failure to stderr
	These programs can print non-fatal diagnostics to stderr prior to

	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

	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

	emit_ancillary_info() and update it to not print the translation
	project address in en_* locales, and _do_ print it in the 'C'
	(and other) locales so that it's included in the default man page.
	Also mention how to invoke the texinfo documentation for each command.
	Also move the "hard-locale.h" include to the 8 files that now use it.

	In addition, GNU tail excludes "-" arguments from the list of files

	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

	df: don't fail due to an unreadable argument
	* src/df.c (main): If open or fstat fails when we're trying to ensure
	that all arg-partitions are automounted, fall back on using stat.
	Inspired by the report and patch from Olivier Fourdan in
	http://bugzilla.redhat.com/520630.
	* NEWS (Bug fixes): Mention it.
	* tests/df/unreadable: New test for the above.
	* tests/Makefile.am (TESTS): Add df/unreadable.
	The bug was introduced in coreutils-7.3 via commit dbd17157,

	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.
	* tests/tail-2/wait: Likewise.

	cp: don't leak resources for each xattr preservation failure

	ls -i: print consistent inode numbers also for mount points
	On most unix- and linux-based kernels, ls -i DIR_CONTAINING_MOUNT_POINT
	would print the wrong inode number for any entry that is a mount point.
	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
	This bug was introduced by the 2006-02-26 commit, 33eb3efe:
	"In ls, avoid calling stat for --inode (-i), when possible."
	* tests/ls/readdir-mountpoint-inode: New test.
	* tests/Makefile.am (TESTS): Add it.
	* tests/ls/stat-vs-dirent: Don't suppress failure of this test,
	now that ls -i is fixed.  Though note that it doesn't test well,
	since it compares only the always-stat'd command-line arguments.
	* NEWS (Bug fixes): Mention it.

	Use gnulib's new priv-set module and updated write-any-file.
	With them, the remove-called can_write_any_file function no

2009-04-22  Jim Meyering  <meyering@redhat.com>

	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.
	* tests/Makefile.am (TESTS): Add cp/proc-short-read.
	* NEWS (Improve robustness): Mention this change.

	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
	http://sourceware.org/bugzilla/show_bug.cgi?id=9859
	* NEWS: Mention the fix
	* gl/lib/mbsalign.c: A new module to align and truncate a
	string in a specified number of screen cells, while handling
	multi-byte characters appropriately.
	* gl/lib/mbsalign.h: Ditto
	* gl/modules/mbsalign: 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%).
	* tests/ls/abmon-align: A new test to test ls alignment for
	various formats and locales

	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.

	* doc/coreutils.texi (shred invocation): Update the description
	of the --iterations option to have the correct default number,

	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

	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?

	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,

	* src/timeout.c (apply_time_suffix): Change input parameter from
	unsigned int to unsigned long, which is the type of the variable it's

	* 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

	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.

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.

	(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.

	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

	* 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.

2008-10-13  Jim Meyering  <meyering@redhat.com>

	doc: adjust spacing in ls --help output, for better man formatting
	* src/ls.c (usage): Adjust spacing so the "Exit status:" list
	renders well in the help2man-generated man page.

2008-10-13  Ondřej Vašík  <ovasik@redhat.com>

	doc: ls: clarify exit status description
	* src/ls.c (exit_status): Clarify comments.
	(usage): Clarify exit status description in --help output.
	* doc/coreutils.texi (ls invocation): Clarify exit status documentation
	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.

2008-10-10  Jim Meyering  <meyering@redhat.com>

	bootstrap: merge from gnulib

2008-10-07  Ondřej Vašík  <ovasik@redhat.com>

	* doc/coreutils.texi: Document runcon and chcon.
	Add minimal SELinux context section.

2008-10-06  Ondřej Vašík  <ovasik@redhat.com>

	chcon: remove traces of unimplemented --change (-c) option
	This option was never supported in upstream coreutils.
	* chcon.c (usage): Remove --change (-c) from help message.
	(main): Remove 'c' from getopt string.
	Remove related and now-unused enums.

2008-10-06  Andreas Dilger  <adilger@sun.com>

	stat: add lustre filesystem type
	* src/stat.c (human_fstype) [S_MAGIC_LUSTRE]: Add case.
	Make "stat -f" recognize the "Lustre" filesystem type.
	<http://en.wikipedia.org/wiki/Lustre_(file_system)>
	* NEWS: Mention this feature.

2008-10-06  Jim Meyering  <meyering@redhat.com>

	remove.c: avoid compile failure on OS/2
	* src/remove.c (dirent_inode_sort_may_be_useful): Guard also with

2008-10-04  Jim Meyering  <meyering@redhat.com>

	tests: fix the install/strip-program test
	* tests/install/strip-program: Use $PREFERABLY_POSIX_SHELL,
	not POSIX_SHELL.  The latter may be empty, and would fail
	on OpenBSD 3.9.
	* tests/check.mk (TESTS_ENVIRONMENT): Propagate
	PREFERABLY_POSIX_SHELL to tests.

2008-10-03  Jim Meyering  <meyering@redhat.com>

	timeout.c: don't use perror; exit 125 upon failed fork
	* src/timeout.c (main): Use "error", not perror.
	Elbert Pol noticed a build failure on OS/2.
	* src/timeout.c (main): Exit 125 (not errno) upon failed fork.
	Make the failed fork diagnostic match the one from install.c.

2008-10-03  Kamil Dudka  <kdudka@redhat.com>

	ls and sort: use filevercmp instead of strverscmp
	* src/ls.c (cmp_version): Use filevercmp instead of strverscmp.

2008-10-02  Jim Meyering  <meyering@redhat.com>

	tests: skip a root-only test when configured without libcap
	* tests/ls/capability: Test for HAVE_CAP definition in config.h.

2008-10-02  Eric Blake  <ebb9@byu.net>

	ignore additional built file

	remove.c: allow compilation on cygwin
	* src/remove.c (dirent_inode_sort_may_be_useful)
	[!HAVE_STRUCT_DIRENT_D_TYPE]: Elide definition when there is no point
	in trying to use it.

2008-10-02  Jim Meyering  <meyering@redhat.com>

	bootstrap: merge from gnulib
	* bootstrap: add submodule support, git-merge-changelog

2008-10-01  Jim Meyering  <meyering@redhat.com>

	remove.c: combine two helper functions, to avoid sign-extension
	* src/remove.c (fs_handles_readdir_ordered_dirents_efficiently):
	Remove function, so as not to have to worry about the type of
	statfs.f_type and sign extension.
	(dirent_inode_sort_may_be_useful): Adjust comment.
	Perform the switch directly on the struct.member here, instead.
	Andreas Schwab spotted the potential for a sign-extension bug,
	that happens not to bite for the S_* f_type values currently used.

	rm: don't preprocess a directory on a file system of type tmpfs or nfs
	The preprocessing phase is not necessary on tmpfs, and induces
	a 20% performance decrease when removing a 2M-entry directory.
	* src/remove.c (fs_handles_readdir_ordered_dirents_efficiently):
	(dirent_inode_sort_may_be_useful): New functions from gnulib/fts.c.
	They'll probably become a gnulib module -- eventually.
	(preprocess_dir): Use dirent_inode_sort_may_be_useful.

	tests: use our new timeout program
	* tests/rm/ext3-perf: Also, record set-up duration and FS type.

2008-09-29  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

	fix make variable quotation error
	* tests/check.mk (TESTS_ENVIRONMENT): Quote shell variable
	$tmp__, fix expansion.

2008-09-29  Jim Meyering  <meyering@redhat.com>

	seq: solve e13188e7ef7bbd609c1586332a335b4194b881aa more cleanly
	* src/seq.c (print_numbers): Don't switch c_strtold -> strtold
	in order to accommodate the locale-dependent behavior of our internal
	asprintf use.  Instead, simply set the locale to C before calling
	asprintf, and then set it back afterwards.

2008-09-28  Jim Meyering  <meyering@redhat.com>

	build: avoid spurious valgrind warning about uses of touch
	* .vg-suppressions (utimensat-NULL): Avoid bogus valgrind warning
	that appears on at least Fedora 9.

	THANKS: add Erik Auerswald

2008-09-28  Eric Blake  <ebb9@byu.net>

	remove.c: avoid compiler warning
	* src/remove.c (compare_ino, dirent_count)
	[!HAVE_STRUCT_DIRENT_D_TYPE]: Mask declaration when unused.

2008-09-27  Jim Meyering  <meyering@redhat.com>

	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
	ext3 and ext4 file systems.  With them, it would take hours to remove
	a two-million-entry directory.  RAM-backed file systems (tmpfs) are
	not affected, since there is no seek penalty.
	* remove.c (rm_malloc, rm_free, compare_ino): New functions.
	(dirent_count, preprocess_dir): New function.
	[struct readdir_data]: New struct.
	(remove_cwd_entries): Call preprocess_dir.
	* tests/rm/ext3-perf: New file.  Test for the performance fix.
	* NEWS: mention the new feature

2008-09-27  Jim Meyering  <meyering@redhat.com>

	remove.c: don't use xmalloc; don't let obstack call exit on failure
	(obstack_chunk_alloc, obstack_chunk_free): Don't define.
	(top_dir): Param is no longer "const".
	Use malloc, not xmalloc, and call longjmp upon failed malloc.
	(obstack_init_minimal): New function.
	(ds_init): Don't use xmalloc.  Instead, use caller-supplied buffer.
	Use obstack_specify_allocation_with_arg, not obstack_init, so
	that we control what happens upon allocation failure.
	Arrange for ds_free not to free uninitialized if/when
	any obstack_specify_allocation_with_arg allocation fails.
	(ds_free): Don't free DS, now that it's no longer malloc'd.
	(rm): Allocate DS on the stack.
	Arrange to handle ds_init allocation failure.

	step1

2008-09-27  Jim Meyering  <meyering@redhat.com>

	* maint.mk (my-distcheck): remove duplicate c99-related test code

	maint: allow more C99 constructs; stop maintaining c99-to-c89 patch set
	* cfg.mk (local-checks-to-skip): Add patch-check.
	With the recent changes to remove.c, I no longer wish
	to maintain the c99-to-c89 patch set.

2008-09-26  Jim Meyering  <meyering@redhat.com>

	seq -0.1 0.1 2: print final number when locale's decimal point is ","
	* src/seq.c (print_numbers): Use strtold, not c_strtold to convert
	from just-formatted-using-asprintf string back to double, since
	asprintf may have used something other than "." as the decimal point.
	Reported by lsof@nodata.co.uk as <http://bugzilla.redhat.com/463556>.
	Thanks to Ondřej Vašík for discovering that the bug was locale-related.

	    $ LC_ALL=cs_CZ.UTF-8 seq -0.1 0.1 2|grep 2.0
	    [Exit 1]
	    $ seq -0.1 0.1 2|grep 2.0
	    2.0

	* tests/check.mk (TESTS_ENVIRONMENT): Add LOCALE_FR_UTF8, for...
	* tests/misc/seq [locale-dec-pt]: New test for the above.
	* NEWS (bug fix): Mention it.

2008-09-26  Jim Meyering  <meyering@redhat.com>

	maint: relax a check so "make distcheck" succeeds again
	* maint.mk (makefile-check): Relax the check, in order to exempt
	the necessary use of a sole @...@-delimited Makefile.am variable.

2008-09-24  Jim Meyering  <meyering@redhat.com>

	maint: avoid using find -name Makefile.am; could get false positives
	* maint.mk (makefile-check): Instead, search for the offending
	@...@ construct only in version-controlled files.

2008-09-24  Benno Schulenberg  <bensberg@justemail.net>

	pinky: gettextize two missed strings
	Additionally differentiate the strings for unknown idle time and
	unknown real name so they can be translated differently.

2008-09-24  Jim Meyering  <meyering@redhat.com>

	cp.c: adjust a comment to make it consistent with documentation
	'-a' is equivalent to -dpR, so s/-dpPR/-dpR/;  the -P is redundant,
	since -d already implies -P, and both --help and "info cp" say -dpR:
	Corresponding doc changes: 080ac7785071c7f135711a39e57c71d9057d9bd7
	b7c2db676635518c06add0dd570543ae83e21f2e.

	warning, and wrong initialization order.

2008-09-22  Benno Schulenberg  <bensberg@justemail.net>

	doc: alphabetize 'who's option descriptions

2008-09-19  Benno Schulenberg  <bensberg@justemail.net>

	who --help: add a general description

	uptime --help: put together message parts that belong together

	Breaking a paragraph into several strings is awkward for translators.

	tail: gettextize the string, "standard input"

	tail --help: move the --retry entry into alphabetical order
	* src/tail.c (usage): Also simplify --retry description, split a
	long string in two, remove a stray period, and add the usual indent.

	shred --help: lowercase a stray capital

	stty --help: correct the alignment of an entry
	* src/stty.c (usage): Also remove a stray period, and ungettextize
	a debugging message.

	sort --help: sort the options better alphabetically
	Take the opportunity to split the long message into three parts.

	rmdir --help: use lower case in option description; adjust indentation

	remove.c: move comment to right before string, so gettext will pick it up

	pr --help: elide arguments after short options that allow a space
	* src/pr.c (usage): Also, put the -S option with its description.

	od: ungettextize debugging messages

	nohup, remove, tr: also gettextize the alternative messages

	od --help: avoid concatening two messages without a newline
	src/od.c (usage): Better: make them into two separate paragraphs.

	mkfifo, mknod --help: put -Z option in its alphabetical position
	Options are normally sorted by their short form, not their long form.
	Also line up their descriptions.

2008-09-19  Jim Meyering  <meyering@redhat.com>

	doc: coreutils.texi (csplit invocation): Add an example.

2008-09-14  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

	(printf invocation): Invoke via "env" rather than using a
	literal /usr/local/bin/ prefix in examples.

2008-09-10  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

	simplify installation rules, using new Automake
	This relies on development Automake to provide multi-file
	installation, and avoids relying on undocumented Automake
	interfaces.  It also removes special-casing for `['.
	* configure.ac (AM_INIT_AUTOMAKE): Depend on 1.10a.
	(CROSS_COMPILING): New Automake conditional.
	* src/Makefile.am (install-exec-am, filtered_PROGS)

	tests: don't use "local" in bourne shell scripts
	* tests/test-lib.sh (remove_tmp_, skip_if_mcstransd_is_running_):
	Avoid failure on Solaris 11, since their /bin/sh passes the tests
	in posix-shell.m4, yet does not support "local" (which is not POSIX).

2008-09-10  Jim Meyering  <meyering@redhat.com>

	tests: use "Exit $fail", not (exit $fail); exit $fail
	* tests/test-lib.sh (Exit): New function by Ralf Wildenhues in automake
	http://git.sv.gnu.org/gitweb/?p=automake.git;a=commitdiff;h=20594c08f63
	* tests/**: Convert all uses:

	This restrictive change converted the vast majority:

	  git grep -l '^(exit \$fail); exit \$fail$' \
	    | xargs perl -pi -e 's/'^\(exit \$fail\); exit \$fail$/Exit \$fail/'

	And this did the rest, plus a few undesirable ones, so I manually
	backed out the changes to ChangeLog-* and build-aux/check.mk:

	  git grep -l -E '\(exit [^)]+\); exit ' \
	    | xargs perl -pi -e 's/\(exit (.+?)\); exit \1/Exit $1/'

2008-09-08  Jim Meyering  <meyering@redhat.com>

	(main): parse these options with getopt_long instead of

	* src/truncate.c: Explicitly convert from off_t to intmax_t
	when printing numbers as they may be different types.

	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

	Revert "id bug fix: don't point to potentially clobbered static storage"
	This reverts commit f7d1c59c224f81a8bab5fa2afcaf815988f50467.

2008-04-21  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.

	pr -e, with a mix of backspaces and TABs, could corrupt the heap
	* tests/pr/Test.pm: New tests for the above.
	* src/pr.c (char_to_clump): Ensure that "input_position" never
	goes below 0.
	Also, elide any backspace encountered when input_position is 0,
	to be compatible at least with /bin/pr from Solaris 10.
	This bug is present in the original version:
	b25038ce9a234ea0906ddcbd8a0012e917e6c661
	* NEWS [Bug fixes]: Mention this.
	Report and diagnosis by Cristian Cadar, Daniel Dunbar and Dawson Engler

	* src/dircolors.hin: Add .flv.  Move .svgz to "image formats".

2008-04-19  Jim Meyering  <meyering@redhat.com>

	md5sum -c: ignore a line with a NUL byte among checksum hex digits
	* src/md5sum.c (hex_digits): Require that all "digest_hex_bytes"
	be hexadecimal digits, not just those before the first NUL byte.
	This bug dates back to the original version:
	3763a4f24eb21be40674d13ff7b04e078f473e85

	tests: accommodate built-in mknod more cleanly still
	* tests/mkdir/selinux: Use "env" rather than "nice".

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
	* tests/mkdir/selinux: Skip the mknod test if it's a built-in.

	* tests/misc/sha1sum (bsd-segv): Likewise.
	* NEWS: Mention the bug fix.

2008-04-14  Jim Meyering  <meyering@redhat.com>

	tests: don't fail on systems without a "stat" syscall
	* tests/test-lib.sh (require_strace_): Add a syscall parameter.
	* tests/ls/stat-free-symlinks: Update caller.
	* tests/mv/atomic: Likewise.

	Reported by Peter Fales.

	seq: work around floating point inaccuracies on more systems
	* src/seq.c: Include <math.h> for fabs.
	Include <float.h> for DBL_EPSILON.
	(abs_rel_diff): New function.
	(print_numbers): Use abs_rel_diff rather than a strict equality test.
	Without this change, Solaris 8 and Irix 6.2 would fail the float-6
	test.  Reported by Peter Fales in
	http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/13183
	* src/c99-to-c89.diff: Adjust seq.c offsets.

	* tests/mkdir/selinux: Also handle "Function not implemented".

	Avoid link failure when using mkstemp replacement.
	* src/Makefile.am (tac_LDADD): Add $(LIB_CLOCK_GETTIME).
	This is necessary at least on a DEC Alpha OSF/1 4.0F.

	tests: always enable VERBOSE output, now that test framework works better
	* cfg.mk: Set VERBOSE=yes.
	* tests/check.mk: Likewise.

2008-04-11  Jim Meyering  <meyering@redhat.com>

	doc: avoid "make pdf" failure (due to texi2dvi bug?)

	remove.c: accommodate systems with negative errno values
	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).
	(prompt): Deal with the changed semantics of the above function.
	Based on this patch from Axel Dörfler:
	http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/13071

2008-04-05  Jim Meyering  <meyering@redhat.com>

	Accommodate building on OS/2 (www.ecomstation.com Ecs v2 rc4)
	* configure.in: Also filter out carriage returns from the value
	of $no_install_progs_default.  Reported by Elbert Pol.

2008-04-02  Jim Meyering  <meyering@redhat.com>

	"touch E; mkfifo F; cp -fR F E" no longer fails due to existing E
	* src/copy.c (copy_internal): Revert change of 2005-03-01,

	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.
	* tests/test-lib.sh (require_root_): This avoids failure of a
	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:
	http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/13071

	* lib/fd-reopen.c: Work even if FILE is "/dev/stdin".
	Problem reported by Geoffrey Lee in <http://bugs.debian.org/290727>.
	* tests/dd/misc: Check for this bug.

2008-03-29  Jim Meyering  <meyering@redhat.com>

	avoid failure of new test on kernel without SELinux support
	* 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.

	Work around a recent glibc/getopt.c diagnostic change.
	* tests/misc/factor: Map new "-- '1'" to expected "-- 1".

2008-03-28  Jim Meyering  <meyering@redhat.com>

	paste -d\\: avoid heap overrun for backslash at end of delim list
	* src/paste.c: Include "quotearg.h".
	(collapse_escapes): Handle backslash-escaped backslash explicitly.
	Handle unescaped backslash at end of string by returning nonzero,

	the static storage containing results from the first call is
	invalidated by the second call.
	* src/id.c (main): Point to a copy of the user name string.

2008-03-22  Jim Meyering  <meyering@redhat.com>

	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:
	'/\(re\)/{s/\(re\)/\1/;...<NEWLINE>}'.  Reported by Vincent Lefevre:
	<http://thread.gmane.org/gmane.comp.gnu.coreutils.bugs/13013>.

	* tests/misc/ptx-overrun: New file.  Test for the above fix.
	* NEWS: Mention the fix.

	ptx.c readability
	* src/ptx.c (copy_unescaped_string): Add braces around 80+-line
	single-stmt while-loop body.

	Write NEWS and update c99-to-c89 patch for today's rm improvement.
	* 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.

	* GNUmakefile: Update from gnulib.

2008-03-20  Jim Meyering  <meyering@redhat.com>

	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>

	Sync GNUmakefile with gnulib.
	* GNUmakefile (Makefile.cfg): Rename...

	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.
	* NEWS: Mention the bug-fix.
	[Bug introduced in 367719ba5f1dbd5e2f7fa2466c441f23f66a7c9e]

	"make" would not always update man/*.1 files (but "make dist" would)
	* man/Makefile.am (BUILT_SOURCES): Define, so that "make" always
	updates man/*.1 files.  Reported by Bob Proulx.

2008-03-18  Jim Meyering  <meyering@redhat.com>

	syntax-check: Make the space-before-open-paren optional.
	* Makefile.maint (sc_prohibit_assert_without_use): Match also

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.
	* GNUmakefile (_is-dist-target): 'distclean' is not a dist target.

2008-03-04  Jim Meyering  <meyering@redhat.com>

	Clarify comment and attribute preceding change: Reported by Ralf Wildenhues.

	Comment out yesterday's VPATH-friendly addition, for now.
	* configure.ac: ...while we wait for a fixed version of automake.

2008-03-03  Eric Blake  <ebb9@byu.net>

	Use m4_PACKAGE_VERSION, not AC_AUTOCONF_VERSION.
	* 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
	<http://article.gmane.org/gmane.comp.gnu.core-utils.bugs/12853>.

2008-03-03  Simon Josefsson  <simon@josefsson.org>

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.
	* tests/misc/help-version: Since groups is no longer a shell
	script, a buggy bourne shell can't cause trouble.

	* configure.ac (AC_INIT): Use .tarball-version, not .version.

	Don't depend on gnulib's deprecated "free" module.
	* bootstrap.conf (obsolete_gnulib_modules): Remove free.
	* gl/modules/mgetgroups (Depends-on): Remove free.

2008-02-29  Jim Meyering  <meyering@redhat.com>

	Merge bootstrap changes from gnulib.
	* bootstrap (MSGID_BUGS_ADDRESS): Define and use.

	* Makefile.maint (VC-tag): Remove '-': s/git-tag/git tag/

2008-02-28  Jim Meyering  <meyering@redhat.com>

	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

	* src/join.c (prevline): Make prevline module-level static, so that
	the allocated items can be freed at exit.
	(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.

	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.
