+2005-01-08  Jim Meyering  <jim@meyering.net>
+
+	* Version 5.3.0.
+
+	`pr --columns=N' was not equivalent to `pr -N' when also using
+	either -s or -w.
+
+	* src/pr.c (main): Set `explicit_columns' for --columns=N,
+	not just for -N.  This bug has existed since the introduction
+	of the --columns=N option on 1998-08-15.
+	* NEWS: Document this.
+	* tests/pr/Test.pm (test_vector): For each -N test, automatically
+	create a new test vector using --columns=N.
+
+2005-01-07  Paul Eggert  <eggert@twinsun.com>
+
+	* src/pr.c (main): Check for column count overflow with
+	usages like "pr -2147483648".
+
+2005-01-07  Jim Meyering  <jim@meyering.net>
+
+	* src/pr.c (init_fps): Use xnmalloc, rather than xmalloc.
+
+2005-01-06  Jim Meyering  <jim@meyering.net>
+
+	* README: List the precise HP-UX version numbers that are affected.
+	Suggestion from Bob Proulx.
+
+	* Makefile.maint (sc_changelog): Specify find's `-maxdepth 2'
+	predicate before `-name ChangeLog' to avoid a harmless warning
+	from find-4.2.10.
+
+2005-01-05  Jim Meyering  <jim@meyering.net>
+
+	* tests/help-version: Punt on the uptime test, since it fails when
+	it can't get boot time, and I don't want that to stop `make check'.
+
+	* src/du.c (process_file): Evaluate exclusion rules against
+	the entire file name, not just the last component.
+	Reported by Robert Lindgren.
+	* tests/du/exclude: Test for this.
+	* NEWS: Document this.
+
+	Ensure that tests/Makefile.am's check-root actions stay up to date.
+	* Makefile.maint (sc_root_tests): New rule.
+	(syntax-check-rules): Add it to the list.
+
+2005-01-04  Jim Meyering  <jim@meyering.net>
+
+	* man/shred.x: Change one-line summary to reflect that shred does
+	not remove files by default.  Suggestion from Helen Faulkner in
+	http://bugs.debian.org/288552
+
+	* README: Request VERBOSE=yes output when reporting test failures.
+	Other minor changes.
+
+	* tests/Makefile.am (check-root): Update.
+
+2005-01-03  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/system.h: Undo previous change; we now use Autoconf.
+
+2005-01-03  Jim Meyering  <jim@meyering.net>
+
+	* tests/stty/row-col-1: Don't set rows or columns to zero, to avoid
+	a bug in the TIOCGWINSZ ioctl on at least Solaris5.9 systems.  Setting
+	either (or both) to zero would succeed, but subsequent `stty size'
+	would say `no size information for this device' due to the ioctl
+	failing with EINVAL.
+
+	* src/system.h: If PRIdMAX, PRIoMAX, PRIuMAX, and PRIxMAX are
+	not all defined and either ULONG_MAX or ULLONG_MAX is not defined,
+	then fail at compile-time rather than let tools like od produce
+	invalid results at run time.
+
+2004-12-21  Jim Meyering  <jim@meyering.net>
+
+	* src/csplit.c (usage): Say the default names are `xx00, xx01, ...',
+	not `xx01, xx02, ...'.
+	Reported by Matt Kraai in http://bugs.debian.org/286605
+
+	* tests/misc/split-fail: Avoid spurious failure on x86 Solaris5.9
+	when using c89.
+
+2004-12-20  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/split.c (usage): Mention default size.  Suggested by Dan Jacobson.
+
+2004-12-19  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* NEWS: Mention that one should eval "`dircolors`" rather than
+	`dircolors`.
+
+2004-12-17  Jim Meyering  <jim@meyering.net>
+
+	* tests/mv/hard-link-1: Rearrange to use newer trap-handling code,
+	so temporary directories aren't left behind upon e.g., interrupt.
+
+2004-12-16  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/ls.c (print_dir): Use "%s: not listing already-listed
+	directory", not "not listing already-listed directory: %s", to
+	format already-listed directories, to be consistent with other
+	diagnostics involving file names and colons.
+
+2004-12-15  Jim Meyering  <jim@meyering.net>
+
+	* src/Makefile.am (__LDADD): Define, so that building `[' on
+	Solaris still uses the -lgen library that it requires in order
+	to get a definition of eaccess.
+
+2004-12-14  Jim Meyering  <jim@meyering.net>
+
+	tac would exit immediately upon I/O or temp-file creation failure.
+	Now it continues on, processing any remaining command line arguments.
+
+	* src/tac.c: Include quotearg.h.
+	Use quotearg_colon in most diagnostics.
+	(copy_to_temp): Rewrite not to exit upon I/O or temp-file-creation
+	failure.  Before, this command (with /full/tmp being a full partition)
+	  TMPDIR=/full/tmp ./tac /proc/modules tac.c
+	would exit immediately upon the write error while trying to copy
+	non-seekable /proc/modules to the full partition.  Now it still
+	reports the failure but continues on with the remaining file.
+	(tac_nonseekable): Return false also if copy_to_temp fails.
+	[DONT_UNLINK_WHILE_OPEN]: Add a FIXME comment explaining that
+	using atexit like this is wrong.
+	* NEWS: Document this.
+	* tests/misc/tac-continue: New test for this.
+	* tests/misc/Makefile.am (TESTS): Add tac-continue.
+
+	* tests/chown/basic: Add a few more tests.
+
+2004-12-13  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/ls.c (gobble_file): Change arg name to be command_line_arg
+	rather than explicit_arg, for consistency with copy.c.
+	(extract_dirs_from_files): Remove ignore_dot_and_dot_dot arg, since
+	it is deducible from dirname arg.  All callers changed.
+	(extract_dirs_from_files, print_dir, queue_directory):
+	Add command_line_arg arg.  All callers changed.
+	(struct pending): Add command_line_arg member.
+	(main): Use NULL rather than 0 when appropriate.
+	(set_exit_status, file_failure): New functions.
+	(queue_directory): Store command_line_arg into new structure.
+	(print_dir, gobble_file, get_link_name):
+	Use file_failure to report problems in accessing files,
+	so that the exit status is set consistently.
+	(print_dir): Simplify readdir failure code yet again.
+	If closedir fails, report "closing directory" rather than "reading
+	directory" failure.
+	(xstrcoll): Use set_exit_status to set status on failure.
+	* tests/ls-2/tests (no-a-isdir-b): This now exits with status 2,
+	not status 1.
+
+2004-12-11  Jim Meyering  <jim@meyering.net>
+
+	Avoid a race condition vulnerability in chown, when used with
+	--from=O:G and without the (-h) --no-dereference option.
+	* src/chown-core.c (restricted_chown): New function.
+	(change_file_owner): Call it.
+	Reported by Ulrich Drepper.
+	* NEWS: Mention this.
+
+2004-12-09  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* ls now exits with status 1 on minor problems, 2 if serious trouble.
+	* NEWS: Document this.
+	* src/ls.c (LS_MINOR_PROBLEM, LS_FAILURE): New constants.
+	All uses of EXIT_FAILURE replaced with LS_FAILURE, unless
+	specified below.
+	(main): Initialize exit failure to LS_FAILURE.
+	(print_dir, gobble_file, get_link_name, xstrcoll):
+	Set exit status to LS_MINOR_PROBLEM if the failure is minor.
+	(print_dir): Do not give up on entire directory merely because readdir
+	returns EOVERFLOW.
+	(usage): Explain exit status.
+	* tests/help-version: ls and variants now exit with status 2
+	on serious trouble.
+
+2004-12-08  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* NEWS: Document new UTC+HH:MM date syntax, and put date changes
+	together.
+
+2004-12-07  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/factor.c (factor): Don't list 1 as a factor of 1.
+	Problem reported by Thomas Folz-Donahue.
+
+2004-12-06  Jim Meyering  <jim@meyering.net>
+
+	* tests/du/files0-from: Sanitize environment.
+	Otherwise, e.g., BLOCKSIZE=k would cause a failure, and that
+	setting is the default (exported from /etc/profile) on at least one
+	NetBSD 1.6 system.
+	* tests/du/no-deref: Likewise.
+	* tests/cp/symlink-slash: Likewise.
+	* tests/ls/symlink-slash: Likewise
+
+2004-12-05  Jim Meyering  <jim@meyering.net>
+
+	* tests/tail/Test.pm (err-6) ["tail -c"]: Avoid test failure when
+	_POSIX2_VERSION=199209 is in the environment, or when building on
+	e.g., OpenBSD 3.2.
+
+2004-12-04  Jim Meyering  <jim@meyering.net>
+
+	* NEWS: Mention cut's new --complement option.
+
+2004-10-01  Paolo Bonzini  <bonzini@gnu.org>
+
+	* cut.c (complement, COMPLEMENT_OPTION): New.
+	(longopts): Add --complement.
+	(usage): Say not that -b, -c, and -f `print' fields,
+	but rather that they `select' fields for printing.
+	Describe the new --complement option.
+	(mark_range_start): Extracted from set_fields.
+	(print_kth): Support --complement.
+	(compare_ranges): New function.
+	(set_fields): Rewrite the part that populates range_start_ht,
+	merging it with the part that populates printable_field.
+	(main): Handle --complement.
+
+2004-12-03  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/tail.c (tail_file): Set errnum to -1 if the initial "tail"
+	failed.  This works around an assertion failure reported by
+	Roberto Nibali in:
+	http://lists.gnu.org/archive/html/bug-coreutils/2004-12/msg00012.html
+
+2004-12-02  Jim Meyering  <jim@meyering.net>
+
+	With using --color and with LS_COLORS saying not to color
+	executables, don't stat every file.
+	* src/ls.c (is_colored): New function.
+	(gobble_file): Use it.
+	(main): Use it here, in place of too-strict tests against NULL:
+	if either ORPHAN or MISSING was set to 0 from LS_COLORS, the
+	old test would fail.
+
+2004-12-01  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/comm.c (compare_files): Assume setlocale exists.
+	* src/join.c (keycmp): Likewise.
+	* src/seq.c (decimal_point): Treat like sort.  Now char.
+	All uses changed.
+	(main): Assume localeconv exists.  Use same code as sort.
+	* src/sort.c (C_DECIMAL_POINT): Remove.  Use changed to '.'.
+	Assume setlocale exists.
+	(thousands_sep): Renamed from th_sep.
+	(IS_THOUSANDS_SEP): Remove.  All uses replaced by comparisons.
+	(NONZERO): Parenthesize use of arg.
+	(numcompare): Avoid duplicate loads.  Use ISDIGIT as boolean, for
+	consistency.  Avoid unnecessary negation by reversing
+	fraccompare args.
+	(main): Rewrite localeconv call to match seq.c.
+	* src/system.h: Assume locale.h exists.
+	(HAVE_SETLOCALE): Remove.
+	* src/uniq.c (different): Assume setlocale exists.
+
+	* src/ls.c (sort_files): Minor cleanup.  Remove an unnecessary
+	'volatile' on a local variable.  Rewrite to avoid unnecessary
+	double-assignment to 'func' in the usual case where strcoll does
+	not fail.
+
+2004-11-30  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/pinky.c (gethostname): Remove decl.
+	(scan_entries): Use IS_USER_PROCESS instead of by-hand code.
+	* src/uptime.c (print_uptime): Use IS_USER_PROCESS and
+	UT_TYPE_BOOT_TIME instead of by-hand code.
+	* src/users.c (list_entries_users): Use IS_USER_PROCESS
+	instead of by-hand code.
+	* src/who.c (USER_PROCESS, RUN_LVL, INIT_PROCESS, LOGIN_PROCESS,
+	DEAD_PROCESS, BOOT_TIME, NEW_TIME, UT_TYPE_UNDEF, UT_TYPE): Remove.
+	(IS_USER_PROCESS): Move to ../lib/readutmp.h.
+	(UT_TYPE_RUN_LVL, UT_TYPE_INIT_PROCESS, UT_TYPE_LOGIN_PROCESS,
+	UT_TYPE_DEAD_PROCESS, UT_TYPE_NEW_TIME): New macros.
+	(gethostname): Remove decl.
+	(list_entries_who, scan_entries): Use the new macros defined above,
+	for consistency with pinky, uptime, and users.
+
+2004-11-25  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Fix problem reported by Scott S. Tinsley for HP-UX 11.11 using
+	HP's ANSI C compiler.  Declaring int functions causes warnings on
+	some modern systems and shouldn't be needed to compile on ancient
+	ones.
+	* src/copy.h (stat, lstat, rename): Remove decls.
+	* src/install.c (stat): Remove decl.
+	* src/ln.c (link, symlink): Remove decls.
+
+2004-11-25  Jim Meyering  <jim@meyering.net>
+
+	* man/help2man: Import help2man-1.35.1.
+	* man/Makefile.am (.x.1): Remove now-unnecessary use of
+	locally-added --program-name=NAME option.  Now, help2man gets
+	the name from the [NAME] section (i.e. from our .x file).
+	* man/install.x: Use `install', not `ginstall' in the one-line
+	description.  Reported by Brendan O'Dea.
+	* man/sha1sum.x: Use `sha1sum', not `shasum'.
+
+2004-11-24  Jim Meyering  <jim@meyering.net>
+
+	Since the changes of 2004-05-22, the u.saved_cwd member at
+	the bottom of the active-directory stack was no longer
+	strictly necessary.  This change removes that member and uses
+	the newer cwd_state parameter for the final restore_cwd.
+
+	* src/remove.c (struct AD_ent) [u]: Remove now-unnecessary union.
+	[dev_ino]: Rename from `a'.
+	(AD_pop_and_chdir): Add a parameter to play the role of just-removed
+	bottom-of-stack cwd-state member.
+	(AD_pop_and_chdir): No longer return boolean.  Adjust caller.
+	(AD_push_initial): Remove CWD parameter.  Adjust caller.
+
+2004-11-23  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Minor performance improvements and cleanups for "touch".
+	* src/touch.c (posix_date): Remove; not needed as a static var.
+	All uses rewritten.
+	(touch): Use new futimens function to operate more efficiently
+	in some cases.  Don't stat/fstat existing file when
+	(!amtime_now && change_times == (CH_ATIME | CH_MTIME)); the
+	old time stamps aren't needed in that case.
+	(main): change_times is int, not bool.  Simplify test for
+	change_times.
+
+2004-11-20  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/install.c (usage): Avoid usage that runs afoul of Docbook
+	translation.  Problem reported by Eric S. Raymond.
+
+	Restore dd's noctty flag, reverting the change of 2004-04-08.
+	POSIX does not allow "dd" to use O_NOCTTY by default.
+	* NEWS: Add noctty flag to dd.
+	* doc/coreutils.texi (dd invocation): Likewise.
+	* src/dd.c (flags, usage, main): Likewise.
+
+2004-11-19  Alfred M. Szmidt  <ams@gnu.org>
+
+	* src/ls.c (usage): Clarified description of --no-group (-G),
+	--human-readable (-h), --inode (-i), --size (-s), --time,
+	and --time-style.
+
+2004-11-19  Jim Meyering  <jim@meyering.net>
+
+	* src/ls.c (usage): Clarify description of --author.
+	Tweak indentation so that help2man creates better nroff.
+	Reported by Dan Jacobson.
+
+	* src/uniq.c (check_file): Don't check stdout for errors here.
+
+	* src/pwd.c (find_dir_entry): Update comment to match reality.
+
+2004-11-18  Jim Meyering  <jim@meyering.net>
+
+	* src/pwd.c (robust_getcwd): Correct the comment: this function
+	constructs the directory name.  The caller prints it.
+
+2004-11-16  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/stat.c (STATFS): New macro, for portability to Solaris 9.
+	(do_statfs): Use it.
+
+	* src/basename.c, src/chroot.c, src/cksum.c, src/dd.c, src/dirname.c,
+	src/factor.c, src/hostid.c, src/hostname.c, src/link.c, src/logname.c,
+	src/nohup.c, src/printenv.c, src/pwd.c, src/setuidgid.c, src/sleep.c,
+	src/sync.c, src/tsort.c, src/unlink.c, src/uptime.c, src/users.c,
+	src/whoami.c, src/yes.c (main): Use getopt_long rather than getopt.
+	* src/readlink.c (main): argv is not const.
+
+	* src/cut.c (usage): Improve documentation along the lines suggested
+	by Debian 5.2.1-2.
+	* src/echo.c (usage): Likewise.
+	* src/expr.c (usage): Likewise.
+
+	* src/dircolors.hin: Add putty, screen-bce.
+
+	* src/pinky.c (print_entry): Fix memory leak.
+	* src/who.c (print_user): Likewise.
+
+2004-11-15  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* NEWS: New dd operand "status=noxfer".
+	* src/dd.c (C_ASCII, C_EBCDIC, C_IBM, C_BLOCK, C_UNBLOCK,
+	C_LCASE, C_UCASE, C_SWAB, C_NOERROR, C_NOTRUNC, C_SYNC, C_TWOBUFS,
+	C_NOCREAT, C_EXCL, C_FDATASYNC, C_FSYNC): Now constants, not
+	macros.
+	(STATUS_NOXFER, statuses): New constants.
+	(usage, print_stats, scanargs): Add support for status=noxfer.
+	(usage): Update status output to match new behavior.
+	(print_stats): Always output complete byte count.
+	Put space between numbers and units, as SI requires.
+	Use ngettext so that i18n can use plurals for "byte" and "second".
+	Don't multiply by 1e-9 (inexact); divide by 1e9 (which is exact).
+	(iflag_error_msgid, oflag_error_msgid): Remove; replace uses by
+	the string.
+	* tests/dd/skip-seek (@Tests): Use status=noxfer to avoid
+	problems with regression testing.
+
+2004-11-14  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* NEWS: dd now outputs total bytes, seconds, and bytes per second.
+	* src/Makefile.am (dd_LDADD): Add $(LIB_CLOCK_GETTIME).
+	* src/dd.c: Include "human.h".
+	(w_bytes, start_time): New vars.
+	(usage): Document new I/O statistics output
+	(print_stats): Output new I/O statistics.
+	(cleanup): Do statistics after closing stdin and stdout, so that
+	the times are more accurate.
+	(write_output, dd_copy): Count output bytes.
+	(main): Get initial value of clock.
+
+2004-11-14  Jim Meyering  <jim@meyering.net>
+
+	Backslash-escape `-'s in email addresses, so that they are
+	rendered properly in UTF-locales.
+	* man/help2man (escape_hyphens): New function.
+	(main): Call it on email addresses.
+
+	* src/sort.c (zaptemp): Mark new diagnostic for translation.
+
+	* tests/misc/close-stdout: New file.  Test today's closeout.c change.
+	* tests/misc/Makefile.am (TESTS): Add close-stdout.
+
+2004-11-13  Jim Meyering  <jim@meyering.net>
+
+	* src/test.c (usage): Put the description of `[-n] STRING'
+	on two lines, one for `-n STRING' and one for `STRING' so that
+	help2man properly escapes the `-'.  Otherwise, the hyphen is
+	rendered inappropriately in UTF-8 locales.
+	Reported by Uwe Zeisberger in http://bugs.debian.org/281069.
+
+2004-11-12  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* NEWS: Document the following changes.
+
+	* src/sort.c: Avoid O(N**2) behavior when there are many temporary
+	files.
+	(temptail): New variable, so that we can easily append to list.
+	(create_temp_file): Create new files at end of list, so that
+	searching the list has O(N*NMERGE) behavior instead of O(N**2).
+	(zaptemp): Update temptail if needed.
+	(mergefps, merge): Accept new arg that counts temp files, and keep it
+	up to date as we create and remove temporaries.  This is for
+	efficiency, so that we don't call zaptemp so often.
+	All callers changed.
+	(sort): Don't create array in reverse order, since the list of
+	temporaries is now in the correct order.
+
+	(zaptemp): Protect against race condition: if 'sort' is
+	interrupted in the middle of zaptemp, it might unlink the
+	temporary file twice, and the second time this happens the file
+	might already have been created by some other process.
+
+	(zaptemp): Warn if a temporary file is not removed.
+
+	(create_temp_file): Use offsetof for clarity.
+	(die): Move it up earlier, to clean up the code a bit.
+
+	* src/pr.c (strtoumax): Declare if not declared.
+	(skip_to_page, first_page_number, last_page_number, page_number,
+	first_last_page, print_header):
+	Use uintmax_t for page numbers.
+	(first_last_page): Remove unnecessary forward declaration.
+	Do not modify arg (it is now a const pointer).
+	Return a true if successful, false (without print a diagnostic)
+	otherwise.
+	(main): If +XXX does not specify a valid page range, treat it
+	as a file name.  This follows the response to Open Group XCU ERN 41
+	<http://www.opengroup.org/sophocles/show_mail.tpl?source=L&listname=austin-group-l&id=7717>,
+	which says the behavior is allowed.
+	(skip_to_page): When starting page number exceeds page count,
+	print both numbers in the diagnostic.
+	(print_header): Detect page number overflow.
+
+2004-11-07  Jim Meyering  <jim@meyering.net>
+
+	* src/uname.c [__APPLE__]: Include <mach/machine.h> and <mach-o/arch.h>.
+	(main) [__APPLE__]: Get the processor type via syscall rather than
+	hard-coding "powerpc".  From Toby Peterson.
+
+	* src/sort.c (merge): Remove declarations of now-unused variables.
+
+2004-11-06  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/sort.c (first_same_file): Remove.  Move most of the code to....
+	(avoid_trashing_input): New function.
+	(merge): Avoid some silly merges, e.g., copying a single file to
+	a temporary file when there are exactly 17 input files to merge.
+	Take a count of temporary files rather than a max_merge arg.
+	All uses changed.
+
+2004-11-06  Jim Meyering  <jim@meyering.net>
+
+	* src/sort.c (xfclose): Don't close stdout here (just flush it),
+	since close_stdout now closes stdout unconditionally.
+
+2004-11-05  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/sort.c (inittables, sort_buffer_size, getmonth, mergefps,
+	first_same_file, merge, sort, main): Use size_t for indexes to arrays.
+	This fixes some unlikely havoc-wreaking bugs (e.g., more than INT_MAX
+	temporary files).
+	(getmonth, keycompare, compare): Rewrite to avoid need for alloca,
+	thus avoiding unchecked stack overflow in some cases.  As a side
+	effect this improve the performance of "sort -M" by a factor of 4
+	on my benchmarks.
+
+2004-11-03  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/stty.c: Include "vasprintf.h" since we use vasprintf now.
+
+	* src/Makefile.am (check-AUTHORS): Don't assume \? works in a sed
+	expression; it's not portable.  Problem reported by Albert Chin.
+	Don't invoke a program more than once.
+	* src/groups.sh (version): New variable, containing author info,
+	for benefit of AUTHORS check.  Use it when acting on --version option.
+	* AUTHORS: Remove duplicate lines.  Remove bogus "chroot:"
+	in groups line.
+
+	* src/system.h: Don't #define and #undef getopt around <stdlib.h>,
+	as this breaks the new regime that does "#define getopt rpl_getopt".
+	Problem reported by Albert Chin for Solaris 9 with Sun cc in:
+	http://lists.gnu.org/archive/html/bug-gnulib/2004-11/msg00019.html
+	I suppose this may cause problems on ancient hosts with
+	incompatible getopt declarations, but we'll cross that bridge if
+	the problem gets reported to us by someone who can test the fix.
+
+2004-11-03  Jim Meyering  <jim@meyering.net>
+
+	* src/tac.c: quote(...) file names in diagnostics.
+
+2004-10-29  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* NEWS: Document getdate changes.
+
+2004-10-29  Jim Meyering  <jim@meyering.net>
+
+	* src/tac.c (tac_file): Remove temporary prototype and move this
+	function `down' so that it precedes definition of tac_nonseekable.
+
+	`tac /proc/modules' would print nothing
+	Reported by Harald Dunkel in http://bugs.debian.org/278604.
+
+	* src/tac.c (copy_to_temp): Renamed from save_stdin, since
+	now it copies a general file descriptor, not just stdin.
+	(tac_nonseekable): Renamed/adapted from tac_stdin.
+	(tac_file): Get fd via `open' directly rather than via fopen/fileno,
+	since we never used the stream.  Perform "-" to stdin mapping here
+	rather than in main.  Determine whether a file is seekable,
+	by trying to `lseek' to its end, and dispatch to tac_seekable or
+	tac_nonseekable accordingly.
+	(main): Rewrite argument handling now that it uses only tac_file.
+	* NEWS: Mention it here.
+
+2004-10-21  Jim Meyering  <jim@meyering.net>
+
+	* tests/mv/leak-fd: New file.
+	* tests/mv/Makefile.am (TESTS): Add it.
+	* tests/rm/dot-rel: New file.
+	* tests/rm/Makefile.am (TESTS): Add it.
+
+	Correct my patch of 2004-10-18.
+	* src/remove.c (rm): Destroy the saved_cwd here (via cwd_state),
+	if necessary, not in remove_dir.  Otherwise, removing multiple
+	`.'-relative nonempty directories no longer worked.
+
+2004-10-20  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/fmt.c (usage): Improve description of --prefix.
+	Problem reported by Edward Welbourne.
+
+	* man/uniq.x: Change summary so that it doesn't imply that
+	uniq writes to its input file.  Problem reported by
+	Dan Jacobson.
+
+2004-10-18  Jim Meyering  <jim@meyering.net>
+
+	Plug a leak that would cause a cross-device mv to fail when
+	operating on too many command-line-specified nonempty directories.
+	* src/remove.c (remove_dir): Destroy the `struct saved_cwd' on the
+	top of the stack before returning.  This usually closes the file
+	descriptor that was used to return to the original working directory.
+	Reported by Cyril Bouthors in
+	http://article.gmane.org/gmane.comp.gnu.core-utils.bugs/3048
+	* NEWS: Mention it here.
+
+	* src/pathchk.c (validate_file_name): Give a more descriptive
+	diagnostic when pathconf fails.  This also avoids an unwarranted
+	warning from gcc-3.3.5 about a format not being a string literal.
+
+	* src/sleep.c (main): Remove declaration of unused local, c.
+	* src/printenv.c (main): Likewise.
+	* src/logname.c (main): Likewise.
+	* src/uptime.c (main): Likewise, for optc.
+	* src/tsort.c (main): Likewise, for opt.
+
+2004-10-17  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* AUTHORS: Add self to pathchk.
+	* src/pathchk.c (AUTHORS): Add self.
+	Change "path" to "file name" whenever possible.
+	Remove usage comment, as it was a duplication of the code or doc.
+	Include <wchar.h> if available.
+	(mbrlen, mbstate_t) [! (HAVE_MBRLEN && HAVE_MBSTATE_T)]: Define.
+	(NEED_PATHCONF_WRAPPER, PATH_MAX, PATH_MAX_FOR, NAME_MAX,
+	pathconf_wrapper, portable_chars, dir_ok): Remove.
+	(NAME_MAX_MINIMUM, PATH_MAX_MINIMUM): New macros.
+	(pathconf, _PC_NAME_MAX, _PC_PATH_MAX): Define if nonexistent.
+	(portable_chars_only): New arg FILELEN.
+	Don't assume ASCII; we might be on an EBCDIC host.
+	Don't assume unibyte locale in diagnostic.
+	(component_start, component_len): New functions.
+	(validate_file_name): Renamed from validate_path.  All uses changed.
+	Pretty much a complete rewrite.
+	Don't make copy of file arg.  Always append trailing slash to
+	pathconf arg, just in case it's a symlink (this is pure paranoia;
+	we don't know of any hosts where the trailing slash is required).
+	Use size_t instead of long int when possible.
+	Avoid need to call pathconf in most practical cases.
+	Don't use euidaccess several times to test searchability;
+	just use lstat once.  Reword diagnostic to put the (often very long)
+	file names last.
+
+2004-10-15  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/printf.c (usage): Mention Unicode, and use H for hex digits.
+
+2004-10-13  Jim Meyering  <jim@meyering.net>
+
+	* NEWS: Mention today's fts.c fix.
+
+2004-10-13  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* tests/stty/row-col-1: Set LC_ALL=C.
+
+2004-10-12  Jim Meyering  <jim@meyering.net>
+
+	* src/dircolors.hin: Add .flac and .mpc as audio suffixes.
+	From Jesus Climent in http://bugs.debian.org/276149.
+
+2004-10-05  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/ls.c (ignore_mode): Renamed from ignore, to avoid shadowing
+	problems.  All uses changed.
+
+2004-10-05  Jim Meyering  <jim@meyering.net>
+
+	* .x-sc_trailing_blank: Add an exclusion for config/texinfo.tex,
+	since Karl says its trailing blanks are there to stay :-)
+
+2004-10-04  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/expr.c (NEW, OLD): Remove, partly to avoid
+	reference to obsolescent macro XMALLOC.
+	All uses replaced by xmalloc and free.
+
+2004-09-28  Jim Meyering  <jim@meyering.net>
+
+	* src/tail.c (usage): Clarify: --retry works only with --follow=name.
+	Reported by Nik A. Melchior in http://bugs.debian.org/273781.
+
+2004-09-27  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/od.c (format_address_paren): c is optional, so don't output
+	it if it's '\0'.
+
+2004-09-26  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Add support for ls --hide.  Idea suggested by Bardur Arantsson.
+	* NEWS: Document this.
+	* src/ls.c (file_ignored): Renamed from file_interesting, with
+	inverted return value.  Accept the file name, not a struct dirent *.
+	All uses changed.  Avoid the expense of calling fnmatch if the
+	file is ignorable due to leading '.'.
+	(all_files, really_all_files): Removed; replaced by:
+	(ignore): New variable.  All uses changed.
+	(IGNORE_DEFAULT, IGNORE_DOT_AND_DOTDOT, IGNORE_MINIMAL, HIDE_OPTION):
+	New constants.
+	(hide_patterns): New variable.
+	(long_options, decode_switches, file_ignored, usage):
+	Add support for --hide.
+	(patterns_match): New function.
+	(usage): Replace "hide" with "ignore" in explanation, to avoid
+	confusion.
+
+2004-09-25  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/ls.c (gobble_file, print_long_format): Don't assume that
+	human-readable output has a byte count equal to its column width;
+	this isn't always true in locales where the radix character is not
+	'.' or ','.
+	(format_user_or_group): Revamp code to match the above fix;
+	this avoids the (very faint) possibility of integer overflow.
+
+2004-09-24  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* NEWS: Mention that "chmod -r -w x" now works as expected.
+	* src/chmod.c (main): Revamp option processing to support this.
+	* tests/chmod/Makefile.am (TESTS): Add 'usage'.
+	* tests/chmod/usage: New set of tests for usage like that.
+
+2004-09-24  Jim Meyering  <jim@meyering.net>
+
+	* Makefile.maint (CVS_LIST): Use --types=AFGM option so that
+	it lists only cvs-controlled regular files.
+
+	* src/csplit.c (xalloc_die): Declare to be `extern', not `static'
+	to avoid a warning from gcc-3.4.1.  Reported by Paul Eggert.
+
+2004-09-23  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* Makefile.maint (CVS_LIST): New macro.
+	(sc_space_tab, sc_prohibit_atoi_atof, sc_file_system,
+	sc_prohibit_jm_in_m4, sc_system_h_headers, sc_sun_os_names,
+	sc_trailing_blank, po-check): Use it instead of the
+	nonstandard "cvsu --list".
+
+	* src/tail.c (parse_obsolete_option): Bring back support
+	for obsolete option followed by non-obsolete, or by more
+	than one file.  When obsolete, conform to SUSv2 rather than
+	original POSIX 1003.2-1992, as SUSv2 corrected the case of
+	"tail -c".  Add support for the SUSv2 "b" modifier.
+	* NEWS: Mention the above.
+	* tests/tail/Test.pm: New test case obs-b to check the above.
+	err-[134] no longer need _POSIX2_VERSION=199209.
+	Fix comments to match revised behavior.
+
+2004-09-22  Jim Meyering  <jim@meyering.net>
+
+	* Use automake-1.9.2.  Regenerate dependent files.
+
+	* src/remove.c (struct dirstack_state) [current_arg_jumpbuf]:
+	Improve the comment.
+
+	Clean up scoping etc. so that some make `distcheck' tests pass.

+	* src/chown-core.c (chown_files): Declare as `extern'.

+	(sc_system_h_headers): Also exclude copy.h; it includes <stdbool.h>.
+
+2004-09-22  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/ls.c (decode_switches): Don't compare a short value
+	to SIZE_MAX: GCC sometimes complains.
+
+2004-09-21  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* NEWS: The following commands now reject unknown options:

+
+	* src/md5sum.c (STATUS_OPTION, STRING_OPTION): New enums.

+	For --string, optarg can't possibly be NULL.
+
+	* src/dd.c (usage): Distinguish between options and operands.
+	(scanargs): Don't mess with argc, argv; getopt_long handles this now.

+	(main): Use getopt_long, so that "dd --" works as POSIX requires.
+	* tests/dd/misc: Check for "dd --".

+	interpreting them as a directory to chroot to.
+
+	* src/cksum.c: Remove obsolete comment about POSIX 1003.2/D11.2.
+	The current standard (POSIX 1003.1-2004) is correct.
+	(crc_remainder) [defined CRCTAB]: Renamed from "remainder" to avoid
+	collision with builtin function.
+	(main) [defined CRCTAB]: Output in lowercase hexadecimal, and

+	the text of the standard.  Output crctab to be a const array.

+	Remove bool *arg; just exit if there's an error.  Revamp to follow
+	POSIX 1003.2-1992 more precisely, to handle cases like "tail -
+	file" and "tail -10 -- file" correctly when we are conforming to
+	the older standard.
+	(main): Adjust to this change.
+	* tests/tail/Test.pm (test_vector): minus-* requires

+	is another file.
+

+
+2004-09-06  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/touch.c (main): Fix POSIX-conformance bug: "touch --
+	MMDDhhmm file" must be treated like "touch MMDDhhmm file" when
+	conforming to pre-2001 POSIX.
+	* NEWS: Document this.
+	* tests/touch/obsolescent: Test for this bug.  Also, set
+	_POSIX2_VERSION=199209 and POSIXLY_CORRECT=1 so that it's
+	a better test for obsolescent features.
+
+	* src/sort.c (main): Emulate Solaris 8 and 9 "sort -y", so that
+	"sort -y abc" is like "sort abc" whereas "sort -y 100" is like
+	plain "sort".
+
+	* src/od.c: Several changes for POSIX and FreeBSD compatibility.
+	(COMMON_SHORT_OPTIONS): Add -B, -D, -e, -F, -H, -I, -L, -O, -s, -X.
+	(long_options, main): --strings is now -S, not -s.
+	(usage): Reflect the usage changes.
+	(parse_old_offset): Do not issue a diagnostic on failure;
+	callers now do this as necessary.
+	(main): Support POSIX syntax.  Remove unused case 0 from getopt_long.
+	Add support for new short options (many undocumented) for
+	compatibility with FreeBSD.  Remove FIXME for -s; it's now
+	POSIX-compatible.  Default format is now oS, not o2.
+	* NEWS: Describe the above.
+
+2004-09-05  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/stty.c (valid_options): Remove.
+	(main): Fix some bugs in handling invalid option-combinations
+	like "stty -F".
+	(recover_mode): Arg is now char const *, not char *.
+	(main): Use STDIN_FILENO, not 0.
+	Simplify option-parsing code a tad.
+	* tests/stty/basic-1: Check for the fixed bugs.
+
+2004-09-03  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/stat.c (HAVE_STRUCT_STATXFS_F_TYPE): Fix typo that prevented

+	to scanargs, so that they're done consistently.
+
+2004-09-02  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Output correct errno-related diagnostic on "paste" I/O errors.

+
+2004-08-24  Paul Eggert  <eggert@cs.ucla.edu>
+
+	POSIX-conformance fixes for "expand" and "unexpand".
+	Also, consistently use "tab stop" rather than "tabstop".
+	* NEWS: Document fixes.
+	* src/expand.c: Revamp to resemble the new unexpand.c better.
+	(usage): -i does not convert tabs after non-tabs.
+	(add_tab_stop): Renamed from add_tabstop.  All uses changed.
+	(parse_tab_stop): Renamed from parse_tabstop.  All uses changed.
+	(validate_tab_stop): Renamed from validate_tabstop.  All uses changed.

+	Add another loop nesting level, for lines, so that per-line variables
+	are initialized cleanly.
+	Revamp tab checking.  Check for write error immediately, rather
+	than just once at the end of the program.
+	* src/unexpand.c: Lkewise (for the expand.c changes).
+	(TAB_STOP_SENTINEL): Remove.
+	(tab_size): Now size_t, not uintmax_t, since we need to store
+	the sequences of blanks.
+	(max_column_width): New var.
+	(usage): Say "blank" where POSIX requires this.
+	(add_tab_stop): Calculate maximum column width.
+	(unexpand): Store the pending blanks, instead of merely counting them.

+	succeed without changing the uid and gid, like FreeBSD.
+	* src/chgrp.c (parse_group): Return gid_t rather than storing it
+	through a pointer.  Treat "chgrp '' file" as a no-op change,

+
+	* src/copy.c (copy_internal): When preserving links, unlink
+	a destination with link count greater than one.  This is so
+	that commands like "cp -a" don't get confused when copying into
+	a destination that already contains many hard links.  Problem
+	reported by Tim Waugh in:
+	http://lists.gnu.org/archive/html/bug-coreutils/2004-08/msg00053.html

+	A null file arg means standard output.
+	(main): "-o -" means to write to a file named "-",
+	not to standard output.
+	* src/tee.c (usage, tee): "tee -" writes to standard output, not
+	to a file named "-".
+
+2004-08-10  Dmitry V. Levin  <ldv@altlinux.org>
+
+	* src/install.c (change_timestamps): Fix int->bool conversion

+
+2004-08-09  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/shred.c (wipename): Work even if the directory is writeable

+
+	* src/md5sum.c: Adjust to sha->sha1 renaming.

+	needed for concatenation contexts.
+	(INTMAX_MAX, INTMAX_MIN): New macros.
+
+	* src/stat.c (print_stat): Don't assume st_ino / st_dev fits in

+
+2004-08-03  Paul Eggert  <eggert@cs.ucla.edu>

+	storing values into exit_status.
+	(expand): Use same pattern as unexpand for reading chars.
+	Report an error when input line is too long, instead of silently
+	screwing up.  Do not mishandle tab stops when backspacing left

+
+	* src/dircolors.c (have_read_stdin, append_quoted,

+	tail_forever, tail_bytes, tail_lines, tail, tail_file,
+	parse_obsolescent_option, parse_options, main): Likewise.
+	* src/sleep.c (apply_suffix): Invert sense of result.
+	Use int (not unsigned int) for multiplier, as this generates better
+	code with some compilers.  Simplify code a bit.
+	* src/tail.c (struct File_spec, max_n_unchanged_stats_between_opens,

+	for state counters.
+	(tail_bytes, tail_lines): Redo test of return value (-1, 0, 1) to
+	make it a bit clearer.
+
+	* src/hostname.c: Include "xgethostname.h".
+	(xgethostname): Remove decl; xgethostname.h has it.
+	(sethostname) [!defined(HAVE_SETHOSTNAME) && defined(HAVE_SYSINFO)

+	(main): No need to pass a non-NULL last arg to getopt_long.
+
+	* src/install.c (isdir): Remove decl.
+	(install_file_to_path): Rely on make_path to fail if the destination
+	is not a directory, by passing preserve_existing==true to it.
+	Hence we no longer need to call isdir.
+	Free dest_dir immediately when it's no longer needed, rather than
+	waiting until the end of the function.
+	(copy_file): Don't bother calling isdir, as copy will do the
+	right thing if the destination is a directory.
+
+	* src/du.c (fts_debug, opt_all, apparent_size, opt_count_all,
+	print_grand_total, opt_separate_dirs, hash_ins, process_file, main):
+	Use bool for booleans.
+	(max_depth): Now size_t, not int, to avoid an arbitrary limit
+	of INT_MAX on depth.
+	(G_fail): Remove: no longer needed, now that the relevant
+	functions return bool.
+	(process_file): Use return value to signal success rather than
+	setting a global.  Remove first_call static var; not needed, since
+	we can look at n_alloc.  Use size_t for depths.  Remove FIXME
+	about size_t casts, as it's now fixed.  Use xnrealloc rather
+	than the obsolescent XREALLOC.  Don't bother to check whether
+	reallocation is needed unless level > prev_level.
+	(du_files): Invert sense of result, for consistency with
+	other coreutils code.  All callers changed.
+	(main): Allow --max-depth values up to SIZE_MAX.

+	(word32): Remove.  All uses changed to uint32_t.
+	(isaac_seed_data): Remove unnecessary cast.
+	* src/system.h (ptr_align): Use size_t; in practice, this is just as
+	good as uintptr_t in checking for alignments, and has fewer
+	configuration hassles.
+
+	* src/Makefile.am (localedir.h): Make it readonly; this
+	undoes part of the 2004-07-27 patch.
+
+2004-07-30  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/sort.c (UCHAR): Remove; all uses changed to to_uchar.
+	(IS_THOUSANDS_SEP): Use bool when appropriate.
+	(numcompare, main): Use char, not int, when the value is always a char.
+	(numcompare): Remove "register"; compilers are smart enough these days.
+	* src/system.h (errno, CHAR_BIT): Remove decls;
+	no longer needed now we assume C89 or better.
+	Include <inttypes.h> before <stdint.h>, as it's the
+	Autoconf-recommended pattern.
+	(to_uchar): New inline function, moved here from tr.c.
+	Use full names for int types, e.g. "long int" rather than "long".
+	* src/tr.c (to_uchar): Remove; now in system.h.

+	Use size_t for sizes.
+	* src/cp.c (target_directory_operand): Do not clear *NEW_DST if stat

+	(do_copy): Rewrite slightly to avoid need for "unreachable" comment.
+	(main): Use EXIT_SUCCESS, EXIT_FAILURE instead of 0, 1.
+	* src/rm.c (main): Likewise.

+	Use bool when appropriate.
+	(digest_check): Increase limit of number of input lines to

+
+2004-07-28  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/cat.c (exit_status): Remove.  Now done by passing a boolean
+	'ok' flag around.
+	(simple_cat, cat): Return true if successful.  All callers changed.
+	(simple_cat, cat, main): Use bool for booleans.
+	(simple_cat): Use size_t for sizes.
+	(cat, main): Use the same names for parameters that we use for
+	long options, to avoid confusion.  This inverts the sense of the
+	show_tabs (formerly output_tabs) and number_nonblank
+	(formerly numbers_at_empty_lines) variables.
+	(main): Don't mess up (due to integer overflow) if we are given
+	INT_MAX - INT_MIN + 1 options.
+	[O_BINARY]: Don't invoke isatty unless the other options require it.
+	(main): When deciding whether to use simple_cat, don't worry
+	about binary option; it's irrelevant.
+
+	* src/dcgen: Remove comments, trailing white space, and empty
+	lines from the output strings, to save space.
+	Use a narrower type like 'unsigned char' for line lengths, if
+	that will do.
+	Make the output variables static, not extern.
+
+	* src/chgrp.c (parse_group): Require base 10 when parsing
+	groups as integers.
+	(main): int -> bool when appropriate.
+	* src/chown.c (main): Likewise.
+	* src/chown-core.c: Include inttostr.h.
+	(UINT_MAX_DECIMAL_DIGITS, uint_to_string): Remove.
+	(gid_to_name, uid_to_name): Use imaxtostr/umaxtostr
+	instead of uint_to_string).
+	(describe_change): Instead of an int flag, use a char *
+	auxiliary; this avoids the need for casts.
+	Assume free (NULL) works.
+	(change_file_owner): Return true/false, not 0/-1, since
+	we don't set errno.  All callers changed.
+	Use bool when appropriate.
+	(chown_files): Likewise.
+	* src/chown-core.h (chown_files): Likewise.
+
+	* tests/chown/basic: Test for proper handling of uids like
+	"010", which must be parsed as decimal.
+
+	* tests/misc/pwd: Don't assume that Perl's getpwd agrees with our
+	pwd when there are multiple names for the working directory
+	(which can happen with an automounter, sigh).
+
+	* src/Makefile.am ($(SCRIPTS)): Don't depend on Makefile;
+	this causes Solaris 8 'make' to refuse to build "groups".
+	(localedir.h): Don't depend on Makefile: this causes Solaris
+	8 'make' to build localedir.h unnecessarily.  The dependence
+	on Makefile is ineffective anyway, since $(localedir) might
+	change even if Makefile hasn't.
+
+	* src/remove.c (remove_dir): If we can't save the state of the
+	working directory, pretend we started from "/", not ".".
+	This avoids a bug on hosts like Solaris that don't let you
+	remove the working directory.
+
+2004-07-27  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/printf.c (strtiomax, strtoumax): Declare if not already
+	declared: this fixes a portability bug with Solaris 8 + GCC.
+	(STRTOX): Parenthesize use of macro arg as expression.
+	(vstrtoimax, vstrtoumax, vstrtold): Remove now-unnecessary
+	parentheses.
+	* configure.ac: Check for declaration of strtoumax, for
+	src/printf.c.
+
+	* src/Makefile.am (cp_LDADD, ginstall_LDADD, mv_LDADD,
+	pathchk_LDADD, rm_LDADD, test_LDADD): New vars, for eaccess.
+
+	* tests/readlink/can-e: Don't assume that we can remove the
+	working directory: this isn't possible under Solaris 8, say.
+	* tests/readlink/can-f: Likewise.
+	* tests/readlink/can-m: Likewise.
+
+	* src/copy.c (copy_internal): find_backup_file_name no longer

+	* src/cp.c (do_copy): Likewise.
+	* src/ln.c (do_link): Likewise.
+
+2004-07-25  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/nice.c (GET_NICE_VALUE): Renamed from GET_PRIORITY.
+	All uses changed.
+	(NZERO): New macro, if system doesn't define it already.
+	(usage): Distinguish priorities from nice values.
+	Don't assume NZERO is 20.
+	(main): Use bool instead of int where appropriate.
+	If user specifies an adjustment out of range, always truncate it
+	to an inrange value instead of sometimes giving an error message
+	and sometimes not.
+	Do not assume that -1 is an error return from "nice" or
+	"getpriority", as it might be the current nice value minus NZERO.
+	If nice/setpriority fails with errno == EPERM, go ahead and run
+	the command anyway; POSIX requires this.
+
+	* src/pathchk.c: Include euidaccess.h.
+	(dir_ok): Use euidaccess, not access.
+	* src/test.c (R_OK, W_OK, X_OK, FOK): Remove; system.h defines them.
+	(eaccess): Remove.  All users changed to use euidaccess instead.
+
+2004-07-24  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/uptime.c (print_uptime) [defined BOOT_MSG]:
+	Don't assume ut_line is null-terminated.
+	* src/who.c (print_line): New arguments USERLEN and LINELEN,
+	since USER and LINE might not be null terminated.  All callers
+	changed.
+
+2004-07-23  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Fix bug with "tail -f" reported by Rob Holland in
+	<http://lists.gnu.org/archive/html/bug-coreutils/2004-07/msg00054.html>.
+	Also, remove the undocumented and unsupported-since-2000
+	--max-consecutive-size-changes options.  Fix another related bug:
+	"tail" got confused if stdin, stdout, or stderr were closed.
+	Also, use output buffering even with "tail -f".
+
+	* NEWS: Document this, plus yesterday's patch.
+	* doc/coreutils.texi (tail invocation): "size has remained the same"
+	-> "file has not changed", which is more accurate for fifos.
+	* src/tail.c: Include fcntl-safer.h.
+	(COPY_TO_EOF): Set to UINTMAX_MAX, not OFF_T_MAX (which was wrong).
+	(COPY_A_BUFFER): New macro.
+	(struct File_spec): New members mtime, mode, blocking.
+	Remove member n_consecutive_size_changes.
+	(DEFAULT_MAX_N_CONSECUTIVE_SIZE_CHANGES,
+	max_n_consecutive_size_changes_between_opens,
+	MAX_CONSECUTIVE_SIZE_CHANGES_OPTION): Remove.
+	(long_options, tail_forever, parse_options):
+	Remove (non-)support for --max-consecutive-size-changes.
+	(record_open_fd): New function.
+	(recheck, tail_file): Use it.  Don't assume that stdin is open.
+	(dump_remainder): Add support for new COPY_A_BUFFER special value.
+	Treat errno==EAGAIN like EOF, since it might be a nonblocking read.
+	(recheck): New arg BLOCKING, specifying whether to use blocking reads.
+	All uses changed.
+	(n_live_files): Remove, replacing with...
+	(any_live_files): New function.  All uses changed.
+	(tail_forever): Use nonblocking I/O unless we know that blocking I/O
+	is safe; this avoids some hangs when reading from a fifo.
+	Avoid invoking fstat or sleep when using blocking I/O.
+	Do not check for changes to size if the file is not a regular file,
+	as the size is undefined in that case.
+	Check for changes to mtime or mode, too; this works for non-regular
+	files.
+	(tail_forever, main): Redo fflush strategy to work even when input
+	is nonblocking.  Don't use unbuffered output; just flush when needed.
+
+2004-07-22  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/tail.c (main): Ignore -f if no file operand is specified
+	and standard input is a pipe.
+	* doc/coreutils.texi (tail invocation): Do not ignore -f for
+	all pipes, just for when standard input is a pipe and no
+	file operand is specified.
+	* tests/tail/Test.pm: Reinstate f-1 test, since we now pass.
+	Add a new commented-out f-2 test, which we still fail.
+	(test_vector): All f-* tests are special cases, not just f-1.
+
+2004-07-12  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/uptime.c: Include c-strtod.h.
+	(print_uptime): Use c_strtod instead of setlocale and sscanf.
+	Use long int rather than int to count days (for 64-bit hosts),
+	and check for arithmetic overflow when converting double to time_t.
+
+2004-07-11  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/printf.c (vstrtold): Renamed from vstrtod.
+	Now returns long double.  All uses changed.
+	(print_direc): Use "L" length modifier when printing floating point
+	numbers, since we're now printing long double.
+
+2004-07-06  Paul Eggert  <eggert@cs.ucla.edu>
+
+	printf cleanup, to avoid undefined behavior, to add support for
+	formats that Bash supports, and to support wide integers like
+	Bash does.
+
+	* NEWS: Document this.
+	* src/printf.c (UNSPECIFIED): Remove.  All uses now replaced by
+	booleans, so that we don't reserve any values for precision or
+	width (like Bash).
+	(STRTOX): Use prototype, not K&R-style definition.
+	(vstrtoimax): Renamed from xstrtol (to avoid confusion with xstrtol
+	in ../lib), with type change to intmax_t.
+	All uses changed.
+	(vstrtoumax): Renamed from xstrtoul, with type change to uintmax_t.
+	All uses changed.
+	(vstrtod): Renamed from xstrtod.  All uses changed.
+	(print_direc): Use boolean arg instead of special value to indicate
+	a missing precision or width.  LENGTH no longer includes
+	length modifiers or conversion character.  New arg CONVERSION
+	now specifies conversion character.
+	Use intmax_t-width formatting for integers (like Bash).
+	Add support for C99 %a, %A, %F (like Bash).
+	Add support for field width with %c (POSIX requires this).
+	Add a FIXME for lack of support for field width and precision
+	for %b.
+	Add support for '\'', '0' flags.
+	Check for invalid combinations of flags, field width, precision,
+	and conversion, to prevent use of undefined behavior.
+	Allow multiple length modifiers, for formats like "%lld" (like Bash).
+	Add support for C99 'j', 't', 'z' length modifiers (like Bash).
+	In error message, output entire invalid conversion specification,
+	instead of merely outputting % followed by the conversion char.
+	* tests/misc/printf: Add tests for the above.
+
+2004-04-03  Dmitry V. Levin  <ldv@altlinux.org>
+
+	Change "readlink -f" to be more compatible with prior implementations.

+	* src/cp.c (do_copy): Likewise.
+	* src/mv.c (movefile): Likewise.
+
+	* src/cp.c (make_path_private): 2nd arg is now size_t, not int,
+	to avoid problem when path_concat dir name is longer than 2 GiB (!).
+
+	* src/nohup.c (main): Don't pass NULL first argument to path_concat.
+	This cleans up the semantics a bit, as we no longer try to open the
+	same file twice.
+
+2004-07-01  Paul Eggert  <eggert@cs.ucla.edu>

+
+2004-06-25  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Add support for 'install --target-directory', an option

+
+	Use more-consistent rules among cp, ln, and mv when dealing with
+	last operands that are (or look like) directories.
+
+	* src/cp.c (target_directory_operand): New, nearly-common function,
+	It reports an error if the destination appears to be a directory
+	(e.g., because it has a trailing slash) but is not.
+	* src/ln.c, src/mv.c: Likewise.
+	* src/cp.c (do_copy): Use it.
+	* src/ln.c (main): Likewise.
+	* src/mv.c (main): Likewise.
+
+	* src/cp.c (do_copy): Don't assume argc is positive.
+	Don't bother to lstat dest, since copy() will do that for us.
+	Use "const" to avoid the need for cast.
+
+	* src/cp.c (do_copy): Don't output a usage message because of file
+	problems (e.g., an operand is not a directory).  Use it only for
+	syntax.  Standardize on "target %s is not a directory" for the
+	diagnostic.
+	* src/ln.c (main): Likewise.
+	* src/mv.c (main): Likewise.
+
+	* src/cp.c (do_copy): Remove test for trailing slash, since
+	target_directory_operand now does this.
+	* src/ln.c (main): Likewise.
+	* src/mv.c (movefile): Likewise.
+
+	* src/cp.c (main): Reject multiple target directories.
+	Check whether a specified target is a directory when parsing the
+	options, using stat.  This gives more-accurate diagnostics.

+
+	* src/ln.c (isdir): Remove decl; no longer needed.
+	* src/mv.c (isdir, lstat): Likewise.
+
+	* src/ln.c (do_link): New arg dest_is_dir.  All uses changed.
+	Don't check the destination ourself; rely on dest_is_dir.
+	This way we can avoid lstatting the destination in the
+	usual case, and in the worst case we lstat 1, not 3 times.
+	Don't bother to unlink unless link failed; this saves a syscall.
+	Remove unnecessary backup_succeeded flag;
+	it was identical to "dest_backup != NULL".
+
+	* src/ln.c (main): Use int to count to argc, not unsigned int.
+	This handles negative operand counts.
+	* src/mv.c (main): Likewise.
+
+	* src/mv.c (do_move): Don't call hash_init; expect the caller to
+	do it, for consistency with cp.c and ln.c.  All callers changed.
+	(movefile): dest_is_dir parameter is now bool, not int.
+	(main): Standardize on "missing destination file operand after %s"
+	for the diagnostic, for consistency with cp.c.
+
+	* tests/mv/diag: Don't assume "mv --target=nonexistentdir"
+	will complain about the arg count.
+	Adjust to new (briefer) diagnostics.
+	* tests/cp/fail-perm: Add a test to verify that we get the new
+	diagnostic when failing to copy through a symlink-to-inaccessible-dir.

+
+	* src/ln.c (main): Don't append basename to dest if this

+	* tests/ln/misc: See whether a trailing slash is followed too far.
+
+2004-06-26  Jim Meyering  <jim@meyering.net>

+
+2004-06-22  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/who.c (idle_string, print_user): New arg boottime,
+	specifying the most recent boot time.  All uses changed.
+	(idle_string) Consider a line to be "old" if it hasn't been used
+	since the last boot time.  Watch out for overflow when computing
+	times, and for times in the future.
+	(idle_string): Record latest boot time.
+
+2004-06-22  Jim Meyering  <jim@meyering.net>

+
+	The 2004-06-19 fix for who and pinky was incomplete, as ctime

+
+2004-06-21  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Fix bug: GNU 'ls' didn't count columns correctly if user or group
+	names contained multibyte characters where the column count

+	* src/ls.c (decode_switches): Pay attention to TABSIZE even if

+	* src/pr.c: Include "hard-locale.h".

+
+2004-05-18  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Several fixes to chgrp and chown for compatibility with POSIX and BSD:
+
+	  Check for incompatible options.  When -R and --dereference are
+	  both used, then either -H or -L must also be used.  When -R and -h
+	  are both used, then -P must be in effect.
+
+	  -H, -L, and -P have no effect unless -R is also specified.
+	  If -P and -R are both specified, -h is assumed.
+
+	  Do not optimize away the chown() system call when the file's owner
+	  and group already have the desired value.  This optimization was
+	  incorrect, as it failed to updated the last-changed time and reset
+	  special permission bits, as POSIX requires.
+
+	  Do not report an error if the owner or group of a
+	  recursively-encountered symbolic link cannot be updated because
+	  the file system does not support it.
+
+	* NEWS: Document the above.
+
+	* src/chgrp.c (main): Check for incompatible options.  -R --dereference
+	requires either -H or -L, and -R -h requires -P.  If -H, specify
+	FTS_PHYSICAL as well as FTS_COMFOLLOW; this is faster.  Make this
+	file as much like chown.c as possible.
+	* src/chown.c (main): Likewise.
+
+	* src/chown-core.c (change_file_owner): Use ent->fts_statp only if
+	needed.  Chown a directory only after chowning its children; this
+	avoids problems if the new directory ownership doesn't permit
+	access to the children.  Dereference symlinks before doing
+	ROOT_DEV_INO_CHECK, not after, so that we catch symlinks to /.
+	Do not optimize away the chown() system call when the file's owner
+	and group already have the desired value.  POSIX does not permit
+	this optimization.  Rely on chown and lchown to do the right
+	thing with symlinks and/or -1 arguments, now that we have wrappers
+	to do this.  Use ENOTSUPP not ENOSYS, and ignore all ENOTSUPP
+	errors, not just command-line errors.
+	(chown_files): Pass FTS_NOSTAT to xfts_open if we don't need file status.
+
+	* src/system.h (ENOTSUP): Remove.
+
+	* tests/chgrp/basic: Use chown --from to discover whether the
+	group changed, since chgrp now changes unconditionally.  This
+	complicates the sed script a bit.  Do not specify --dereference,
+	since it's the default (and we want to test this).  Adjust output
+	to match the fact that chgrp no longer optimizes the case of
+	changing a file's group to the same value as before.
+	* tests/chgrp/posix-H: Do not attempt to combine -h and -H; these
+	options are incompatible, and their behavior is undefined with POSIX.
+	(changed, not_changed): Adjust to match the fact that -h is no longer
+	specified.  Sort names.
+	* tests/chown/deref: Adjust error-diagnostic spelling to match new
+	behavior.

+	(dd_copy): Use it, instead of assuming that failed reads
+	do not advance the file pointer.  Advance input offset
+	after nonfailed reads.  Advance only a partial block if
+	the previous read (before the failed read) succeeded, and
+	do not generate an output block of zeros in this case.
+	(main): Determine initial input offset, seekability of input,
+	and error if it wasn't seekable.

+	rm (without -f) could hang unnecessarily when attempting to
+	remove a symlink to a file on an off-line NFS-mounted partition.
+	Reported by David Howells in https://bugzilla.redhat.com/124699.
+	* src/remove.c (write_protected_non_symlink): New function.
+	Don't invoke euidaccess on symlinks.
+	(prompt): Use write_protected_non_symlink rather than using
+	euidaccess directly, being careful not to call lstat twice for a file.
+
+	Fix a bug in how the --output-delimiter=D option works with
+	abutting byte or character ranges.  Reported by David Krider in
+	http://lists.gnu.org/archive/html/bug-coreutils/2004-05/msg00132.html
+	* src/cut.c (print_kth): Remove special case for open-ended range.
+	(set_fields): Record the range start index for an interval even
+	when it abuts another interval on its low side.
+	Also record the range start index of the longest right-open-interval.
+	* tests/cut/Test.pm: Add tests of --output-delimiter=S with
+	abutting and overlapping byte ranges.
+
+2004-06-01  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Some POSIX-conformance cleanups for tr.
+
+	* src/tr.c (posix_pedantic): Remove; no longer needed since
+	we need to test this in just one place now.
+	(usage): Mention -C.
+	(unquote): Note that \055, \n, etc are escaped.
+	Do not worry about POSIXLY_CORRECT when warning about ambiguous
+	escape sequences.
+	\ at end of string stands for itself.
+	Do not diagnose invalid backslash escapes: POSIX says the behavior
+	is unspecified in this case, so we don't need to diagnose it.
+	(main): Add support for -C (currently an alias for -c).
+	Do not diagnose 'tr [:upper:] [:upper:], as POSIX does not require
+	a diagnostic here.
+	* tests/tr/Test.pm: New tests bs-055, bs-at-end, repeat-Compl.
+	Fix comment for range-a-a.
+
+2004-05-25  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Improve the efficiency (and in one case, correctness) of code
+	that reads symlinks.
+
+	* src/copy.c (copy_internal): Don't use alloca, as it can mess up
+	royally if the link length is long (e.g., GNU/Hurd).  Use
+	xreadlink instead, it's safer.  Don't bother to read the link if
+	it's the wrong size.  Add a FIXME because this area is a bit murky
+	and undocumented.
+	* src/ls.c (get_link_name): Update use of xreadlink.
+	* src/readlink.c (main): Likewise.
+	* src/stat.c (print_stat): Likewise.
+

+
+	* NEWS: echo compatibility cleanup.
+	* doc/coreutils.texi (echo invocation): Document the changes.
+	* src/echo.c (V9_ECHO): Remove; always enabled.
+	(DEFAULT_ECHO_TO_XPG): Renamed from V9_DEFAULT, so that
+	we use the same naming convention as bash.  Now an enum,
+	not a macro.
+	(usage): Reword to mention -e/-E more accurately.
+	Mention \0NNN (the POSIX syntax) rather than \NNN (nonstandard).
+	(hextobin): New function.
+	(main): Use bool rather than int for local vars when appropriate.
+	Do not allow options if POSIXLY_CORRECT, unless we are using
+	BSD semantics and the first argument is "-n".
+	Don't pass unnecessary extra arg to parse_long_options.
+	do_v9 now defaults to DEFAULT_ECHO_TO_XPG, not to allow_options.
+	Do not look for options if !allow_options.
+	Use size_t rather than int when appropriate.
+	Open-code option test rather than using strrchr.
+	Use faster test for "-".
+	Avoid redundant argc test.
+	Add support for \x, for Bash compatibility.
+	Use e.g. '\a' rather than '\007', for portability to EBCDIC hosts.
+	When '\c' is encountered, stop printing immediately, as POSIX
+	requires.
+	Add support for \xhh syntax.
+	Add support for \0ooo syntax; POSIX requires this.

+2004-05-31  Jim Meyering  <jim@meyering.net>
+
+	* tests/Makefile.am.in (TESTS_ENVIRONMENT): Define PATH to include
+	the build src/ directory -- at the front.
+	($(srcdir)/$x-tests): Depend on Makefile.am.
+	Use $x as the program name, except when it would be `test' (test is
+	the sole program tested via mk-script that is also a shell built-in).
+	In that case, use the old ../../src/$x.

+2004-05-30  Jim Meyering  <jim@meyering.net>
+
+	Work around HPUX /bin/cc compiler bug that is exposed, now that
+	sets are arrays of type `bool'.  More details here:
+	http://lists.gnu.org/archive/html/bug-gnulib/2004-05/msg00094.html
+	FIXME: verify that the above URL points to the right message
+
+	* src/tr.c (card_of_complement): Use cleaner `sizeof in_set'
+	rather than `N_CHARS * sizeof(in_set[0])'.  Using HPUX's /bin/cc
+	(aC++/ANSI C B3910B A.05.55 [Dec 04 2003]) on an ia64-hp-hpux11.22
+	system, those two expressions are not the same (256 vs. 1024).
+	The effect of this problem was that `tr -c x y' would fail:
+	tr: when not truncating set1, string2 must be non-empty
+	(set_initialize): Remove unnecessary initialization of the `in_set'
+	buffer; that initialization triggered the same compiler bug as above.
+
+2004-05-29  Paul Eggert  <eggert@cs.ucla.edu>
+
+	tr cleanup, mostly having to do with integer type ranges.
+	Remove all casts.
+
+	* tests/tr/Test.pm: Add a few tests for the below.  Alas, most of
+	the test cases wouldn't be portable, or would take too much CPU
+	time, or both.
+
+	* src/tr.c (N_CHARS, N_CHAR_CLASSES): Now an enum, not a macro.
+	This is safe since the code already assumes N_CHARS fits in int.
+	(Filter): Remove: we want to prototype everything.
+	(ORD, CHR): Remove.  All uses removed.  Some replaced with:
+	(uchar): New function.  All places where a char must be converted
+	to an unsigned char are now done this way, not by ad-hoc methods.
+	(count): New type.  Use it whenever counts or states are needed.
+	(BEGIN_STATE): Increase from INT_MAX - 1 (which was bogus, anyway,
+	since we used it in an unsigned int context) to UINTMAX_MAX - 1.
+	(REPEAT_COUNT_MAXIMUM): New macro.  Use it in place of BEGIN_STATE
+	whenever appropriate.
+	(NOT_A_CHAR): Remove global macro; now a local enum.
+	(UL_LOWER, UL_UPPER, UL_NONE): No longer specify values, since
+	the rest of the code no longer depends on them.
+	(class_ok): Remove; all uses changed to use inline comparisons.
+	(RE_NO_TYPE): Remove; wasn't used or needed.
+	(struct List_element): normal_char and equiv_code are now unsigned
+	char, not int.
+	first_char, last_char, and the_repeated_char are now unsigned char,
+	not unsigned int.  repeat_count is now count, not size_t.
+	All uses changed.
+	(struct Spec_list): state is now count, not unsigned int.
+	lengthis now count, not size_t.
+	n_indefinite_repeats is now size_t, not int.
+	has_equiv_class, has_char_class, and has_restricted_char_class
+	are now bool, not int.  All uses changed.
+	(struct E_string): s is now char *, not unsigned char *.
+	escaped is now bool *, not int *.  All uses changed.
+	(ES_MATCH): Remove macro, replacing with:
+	(es_match): New inline function.  All uses changed.
+	(squeeze_repeats, complement, posix_pedantic, truncate_set1,
+	translating): Now bool, not int.
+	(io_buf): Now char array, not unsigned char.
+	(SET_TYPE): Remove.  All uses replaced with bool.
+	(is_equiv_class_member, unquote, append_range, append_char_class,
+	append_equiv_class, find_closing_delim, star_digits_closebracket,
+	build_spec_list, parse_str, homogeneous_spec_list):
+	Now returns bool, not int.  All uses changed.
+	(is_equiv_class_member): Now inline.
+	(is_equiv_class_member, is_char_class_member, make_printable_str,
+	append_normal_char, append_range, append_repeated_char,
+	get_s2_spec_stats):
+	Args are now of proper integer type.
+	(unquote, look_up_char_class, make_printable_str,
+	append_equiv_class, build_spec_list, squeeze_filter):
+	Avoid unsigned char *p; gently convert *p to unsigned char instead.
+	(unquote, get_spec_stats): Do not jump past declarations and then
+	use them; C doesn't allow this in portable programs.
+	(make_printable_str): Check for overflow in size calculations.
+	(xmemdup): Remove.  All uses rewritten.
+	(find_bracketed_repeat): Args are now of proper pointer-to-integer
+	type.  Do not reject [c*0].  Use xstrtoumax, not xstrtoul.
+	(find_bracketed_repeat, star_digits_closebracket): Check that the
+	digits are not escaped.
+	(build_spec_list): Don't bother to copy opnd_str; not needed.
+	(build_spec_list, get_next): Simplify internal logic a bit.
+	(card_of_complement): Fix bug due to char overflow.
+	(get_spec_stats): Don't assume len fits into int.
+	Check for integer overflow.  Use abort() rather than assert(0).
+	(string2_extend): Fix subscript error: is_char_class_member (..., 255)
+	was being invoked.
+	(squeeze_filter): READER is never null now; simplify code.
+	READER arg now has a simpler type.  Remove unnecessary casts.
+	(squeeze_filter, main): Calls to fwrite improperly checked result
+	against zero, rather than against requested size.
+	(plain_read): New function.
+	(read_and_delete, read_and_xlate):
+	Remove unused filter arg, and don't worry about hit_eof.
+	Simplify by using plain_read.
+	(set_initialize): Args are bool and bool *, not int and SET_TYPE *.
+	(main): Always pass a non-null procedure to squeeze_filter.
+	Rewrite so that class_ok isn't needed.

+
+	rm -r would get a failed assertion when run from an inaccessible

+
+	* src/remove.h (struct rm_options) [require_restore_cwd]: New member.
+	* src/remove.c (struct cwd_state): Define.
+	(AD_pop_and_chdir): Redesign interface so that a restore_cwd failure
+	can be detected by the caller.  Instead of returning a malloc'd
+	directory name, communicate it to caller via a new parameter, and
+	return an indication of whether restore_cwd failed.  Update caller.
+	Eliminate an unnecessary call to AC_stack_top.
+	(remove_dir): Change type of cwd_state parameter to `struct cwd_state'
+	so we can now communicate to caller whether/how functions like
+	restore_cwd have failed.  Update caller.
+	(rm_1): Fail if we've failed to restore the working directory
+	and the name of the next file to remove is `.'-relative.
+	(rm): Fail if the require_restore_cwd flag is true and we've
+	failed to restore the working directory.
+	* src/mv.c (rm_option_init): Initialize new member,

+
+2004-05-20  Jim Meyering  <jim@meyering.net>
+
+	* Makefile.maint (sc_unmarked_diagnostics): Now that the unmarked
+	diagnostics in shred.c have been fixed, don't exempt shred.c from
+	this check.
+
+	* src/shred.c: Use translatable diagnostics, e.g.
+	change "%s: remove" to _("%s: failed to remove") and
+	change "%s: close"  to _("%s: failed to close").
+
+2004-05-17  Paul Eggert  <eggert@cs.ucla.edu>
+
+	* src/shred.c (names): Bring back lower-case letters, "_", and
+	".".  But continue to omit +, =, %, @, #, as they're either
+	shell metacharacters (for some shells) or are not in some
+	character sets, or (in the case of '%') must be a

+	chgrp and chown now dereference symlinks by default, per POSIX.
+	Reported by Michal Politowski as http://bugs.debian.org/249177.
+
+	* src/chown-core.c (chopt_init): Affect each symlink referent by default.
+	* src/chown.c (usage): Update to reflect this.

+	* NEWS: Describe the change.
+	Adapt tests accordingly.
+	* tests/chgrp/basic: Use -h where necessary to retain semantics.

+	* tests/chgrp/posix-H: Likewise.
+
+2004-05-15  Paul Eggert  <eggert@cs.ucla.edu>
+
+	In shred, check for errors from fdatasync more carefully.  If
+	fdatasync fails with errno==EINVAL, it means this implementation
+	does not support synchronized I/O for this file.  Do not report
+	this as an error, as (for example) AIX 5.2 fdatasync reports it
+	for raw disk devices.  Problem reported by Albert Chin in
+	<http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00028.html>.
+
+	Check for write errors, though: the old code ignored them.
+	Improve error checking in a few other cases, too (e.g., close of a
+	directory).
+
+	Also, change several 'int' values to 'bool', so that the error
+	checking is a bit clearer.  Similarly, change unsigned values
+	to size_t where appropriate.
+
+	* src/shred.c: Include "dirname.h".
+	(datasync) [!HAVE_FDATASYNC]: Remove.
+	(dosync): New function.
+	(dopass): Use it.  Return 1 on write error, -1 on other error.
+	All callers changed.  Report write error if dosync does.
+	(do_wipefd, wipefd, wipename, wipefile): Return bool (true/false),
+	not int (0/-1).  All callers changed.  Return false if there's a
+	write error.
+	(incname): Return bool (true/false), not int (0/1).  Accept
+	size_t length, not unsigned.  All callers changed.  Do not
+	bother checking for non-digits; it can't happen.  Replace
+	recursion with iteration.
+	(wipename): Use dir_name, base_name, etc. instead of assuming
+	Unix file names.  Use size_t for length, not unsigned.
+	Report error if unlink or close fails.
+	(wipename, main): Use bool for booleans.
+
+	(names): Use only digits and uppercase letters, for greater
+	portability.

+
+2004-05-15  Jim Meyering  <jim@meyering.net>
+
+	chown --dereference did nothing when the owner/group of a
+	symlink matched the desired owner/group.  Reported by David Malone.
+	Also reported in 1999 as http://bugs.debian.org/39642.
+
+	* src/chown-core.c (change_file_owner): When --dereference has

+
+2004-05-14  Jim Meyering  <jim@meyering.net>

+
+	* src/sort.c (first_same_file): Do not treat input pipes

+	* NEWS: Likewise.
+
+2004-05-12  Paul Eggert  <eggert@cs.ucla.edu>
+

+
+2004-05-12  Jim Meyering  <jim@meyering.net>
+
+	* src/remove.c (AD_pop_and_chdir): Move lstat-`.' into if-block

+	per command line argument.
+
+2004-05-12  Paul Eggert  <eggert@cs.ucla.edu>
+
+	Don't assume that "make -C" works; Solaris "make" doesn't have -C.
+
+	* src/Makefile.am (all_programs.list): New rule, copied from
+	man/Makefile.am and tests/Makefile.am, except that we use the
+	system tr rather than ./tr and we don't use tr -s.
+	* tests/Makefile.am (all_programs): Use it.
+	* man/Makefile.am (all_programs): Likewise.  Renamed from programs,
+	for consistency.  All uses changed.
+
+2004-05-11  Jim Meyering  <jim@meyering.net>
+
+	* tests/rm/unread3: New test, for the above fix and today's

+
+	Fix bug where "rm" gave up too easily, reported by Dan Jacobsen in
+	<http://mail.gnu.org/archive/html/bug-coreutils/2004-05/msg00013.html>.
+
+	* src/remove.c (remove_entry): Check for errno values like ENOENT
+	that show the file cannot be directory, instead of for errno
+	values like EPERM that show the file might be a directory.  This
+	is necessary because, when a single unlink() call has multiple
+	reasons to fail, it can set errno to any of those reasons; it's
+	only the rare errno value like ENOENT that excludes all the other
+	possible reasons to fail even when the file is a directory.
+	(remove_cwd_entries): Don't attempt chdir if the file is known
+	to not be a directory.
+	(remove_dir): Use the same method that remove_cwd_entries uses
+	(for some reason they differed).  Don't assert that saved_errno
+	must be EPERM; it might be just about anything.
+
+2004-05-06  Jim Meyering  <jim@meyering.net>
+
+	* src/id.c (xgetgroups): Use xnmalloc, rather than xmalloc.
+	Don't add `1' to the buffer size (it was to protect against malloc
+	implementations that fail to allocate a buffer of size zero).
+	That is no longer necessary, since we use a malloc wrapper

+	(show_disk): Remove unused statp arg.  Return bool, not int.
+	(show_point): Rewrite to avoid gotos.  Use the same algorithm
+	for lofs and dummies for each pass through the mount table,
+	rather than subtly different algorithms (which are probably
+	inadvertent).
+
+2004-05-03  Jim Meyering  <jim@meyering.net>

+
+	When chown or chgrp is modifying the referent of a symlink,

+
+2004-04-27  Jim Meyering  <jim@meyering.net>

+
+	* Use automake-1.8.4.  Regenerate dependent files.
+
+	* src/sort.c (limfield): Make a comment clearer.
+
+2004-04-25  Paul Eggert  <eggert@twinsun.com>
+
+	Fix POSIX-conformance bug: "sort -k 3,3.5b" is supposed to skip
+	leading blanks when computing the location of the field end;
+	it is not supposed to skip trailing blanks.  Solaris 8 "sort"
+	does conform to POSIX.  Also fix the documentation to clarify
+	this and related issues.
+
+	* doc/coreutils.texi (sort invocation): Mention -k earlier, so
+	that the options are in alphabetical order.  Describe how -b works
+	more-accurately; this involves fixing some examples, too.  Mention
+	what happens if the start field falls after an end field or after
+	a line end.  Warn about using -k without -b, -g, -M, -n, or -t.
+	Add an example of how to sort IPv4 addresses and Apache Common
+	Log Format dates.  Remove a duplicate example.
+	(Putting the tools together): Use separate options rather
+	than agglomerating them.
+	* src/sort.c (limfield): Use skipeblanks, not skipsblanks, to
+	decode whether to skip leading blanks.
+	(trailing_blanks): Remove.
+	(fillbuf, getmonth, keycompare): Don't trim trailing blanks.
+
+	* tests/pr/Test.pm: Fix typo in env_default comment.
+	* tests/sort/Test.pm: Likewise.
+	(18c, 18d): Reverse the order of output lines, so that the
+	test cases conform to POSIX.
+
+2004-04-22  Paul Eggert  <eggert@twinsun.com>
+
+	More signal-handling cleanup for ls.c.  Do not allow signals to
+	happen between arbitrary output bytes, as the
+	restore-default-color sequence can bollix up multibyte chars or
+	color-change sequences in the ordinary output.  Instead, process
+	signals only between printing a file name and changing the color
+	back to non_filename_text color.  That way, if the signal handler
+	changes the color (to the default), 'ls' will change it back when
+	'ls' continues (after being suspended).
+
+	Also, do not bother with signal-handling unless stdout is a
+	controlling terminal; this lets stdio buffer better when "ls
+	--color" is piped or sent to a file.
+
+	* src/ls.c (sigprocmask, sigset_t) [!defined SA_NOCLDSTOP]: New macros.
+	Do not include "full-write.h"; no longer needed.
+	(tcgetpgrp) [! HAVE_TCGETPGRP]: New macro.
+	(put_indicator_direct): Remove.  All callers changed to use
+	put_indicator.
+	(caught_signals, interrupt_signal, stop_signal_count): New vars.
+	(restore_default_color): Don't bother checking for put_indicator
+	failure.
+	(sighandler): Don't handle SIGTSTP; that's another handler now.
+	Simply set interrupt_signal to the signal, then exit.
+	(stophandler, process_signals): New functions.
+	(main): Don't output any color changes until _after_ the signal
+	handlers are set up.  This fixes a race condition where 'ls'
+	could be interrupted while initializing colors, and leaving the
+	terminal in an undesirable state.
+	Don't mess with signal-handling if standard output is not a
+	controlling terminal.
+	When exiting, restore the default color, then restore the
+	default signal handling, then act on any signals that weren't
+	acted on yet.
+	Do not print //DIRED// etc. in colors; this avoids the need
+	to catch signals when printing them.
+	(print_name_with_quoting): Process signals just before switching
+	color back to non_filename_text.
+

+
+	Avoid segfault on systems for which SIZE_MAX != (size_t) -1.
+	* src/ls.c (quote_name): Use SIZE_MAX, not -1, in calls
+	of quotearg_buffer.  Patch by Mikulas Patocka.
+
+2004-04-18  Paul Eggert  <eggert@twinsun.com>
+
+	tee ignored SIGPIPE, but POSIX doesn't allow this.
+
+	* src/tee.c (main): Do not ignore SIGPIPE, as POSIX 1003.1-2001
+	does not allow this.  This undoes the 1996-10-24 patch.
+
+2004-04-18  Paul Eggert  <eggert@twinsun.com>
+
+	Signal-handling cleanup for coreutils.  Here are the highlights:
+
+	 - csplit sometimes failed to remove files when interrupted.
+	 - csplit didn't clean up if two signals arrived nearly simultaneously.
+	 - install -s would infloop on System V if SIGCHLD was ignored.
+	 - ls could incorrectly restore color if multiple signals
+	   arrived nearly simultaneously.
+
+	* src/csplit.c (sigprocmask, sigset_t) [!defined SA_NOCLDSTOP]:
+	Define.
+	(filename_space, prefix, suffix, digits, files_created, remove_files):
+	Now volatile.
+	(caught_signals): New var.
+	(cleanup): Block signals while deleting all files.
+	(cleanup_fatal, handle_line_error, regexp_error):
+	Mark with ATTRIBUTE_NORETURN.
+	(create_output_file, close_output_file, interrupt_handler):
+	Block signals while changing the number of output files,
+	to fix some race conditions.
+	(delete_all_files): Do nothing if remove_files is zero.
+	Clear files_created.
+	(main): Don't mess with signals until after argument processing
+	is done.
+
+	* src/csplit.c (main): Rewrite signal-catching code to make it
+	similar to other coreutils programs.  When processing signals,
+	block all signals that we catch, but do not block signals that we
+	don't catch.  Avoid problems with unsigned int warnings.
+	* src/ls.c (main): Likewise.
+	* src/sort.c (main): Likewise.
+
+	* src/csplit.c (interrupt_handler):
+	Use void, not (obsolete) RETSIGTYPE.
+	* src/shred.c (sigill_handler, isaac_seed_machdep): Likewise.

+	for SIG_IGN.
+	* src/tee.c (main) [!defined _POSIX_SOURCE]: Likewise.
+
+	* src/install.c: Include <signal.h>.
+	(main) [defined SIGCHLD]: Set SIGCHLD handler to the default, if -s is
+	given, since System V fork+wait does not work if SIGCHLD is ignored.
+
+	* src/ls.c (sighandler) [!defined SA_NOCLDSTOP]: Reset signal
+	handler to self, not to SIG_IGN, since SIGTSTP can be received
+	more than once.
+	(main): Use SA_RESTART, as that is simpler than checking for EINTR
+	failures all over the place.
+

+
+	* src/remove.c (is_empty_dir): Clarify comment.
+
+	* man/help2man: Accept new option: --program-name=NAME, so that we

+	so that test.1 doesn't refer to `[' as the program name.
+	Reported by Benjamin Cutler as http://bugs.debian.org/205251.

+	* announce-gen (print_changelog_deltas): Use `.sig' suffix for
+	signature files, not `.asc'.  Reported by angico@yahoo.com.
+
+2004-03-13  Jim Meyering  <jim@meyering.net>
+
+	* src/cp.c (do_copy): Tweak wording in a diagnostic.
+	Suggestion from Karl Berry.
+	Include "quoatearg.h".
+	(do_copy): Use quotearg_colon (not quote) for diagnostics
+	that begin with `"%s:'.
+
+	* src/nl.c (usage): Specify that nl uses _basic_ regular expressions.
+	Suggestion from Dan Jacobson.
+
+2004-03-12  Jim Meyering  <jim@meyering.net>
+
+	* Version 5.2.1.
+
+	Sometimes, when source and destination partition are different,
+	mv mistakenly fails to preserve a hard link.  Reported by IIDA Yosiaki.
+
+	* src/copy.c: When moving a set of N hard-linked files between
+	partitions, via two or more command line arguments where the
+	command line argument containing the Nth link contains no other
+	link to that same file, mv would mistakenly copy the file, rather
+	than hard-linking it to the other(s).  That happens because when the
+	final link is processed, its link count has been reduced to 1 since
+	the other links have been `copied' to the destination partition
+	and the source links have been removed.
+	(copy_internal): When in move mode, use the source dev/inode
+	pair to look up destination name even when st_nlink == 1.
+	* src/cp-hash.c (src_to_dest_lookup): New function.
+	* src/cp-hash.h (src_to_dest_lookup): Add prototype.
+	* tests/mv/part-hardlink: New file.  Test for the above fix.
+	* tests/mv/Makefile.am (TESTS): Add part-hardlink.
+
+	* announce-gen: Sync with autoconf.
+
+	* tests/ls/time-1: Exit 77 (not 1) if we can't set up for the test.
+	This was triggered on a Linux-2.2.19 system using a file system
+	NFS-mounted from some sort of Sun.
+
+2004-03-11  Jim Meyering  <jim@meyering.net>
+
+	* Use automake-1.8.3.  Regenerate dependent files.
+
+2004-03-10  Jim Meyering  <jim@meyering.net>
+
+	* tests/du/deref-args: Also convert sizes in the 70-79 kB range,
+	so that this test works with SELinux-enabled systems.
+	Based on a patch from Tim Waugh.
+
+	`join -1 x' would give a misleading diagnostic
+	* src/join.c (string_to_join_field): Report that a non-numeric field
+	number is invalid, rather than `so large that it is not representable'.
+	* tests/join/Test.pm (invalid-j): New partial test for the above fix.
+
+2004-03-06  Jim Meyering  <jim@meyering.net>
+
+	cp --sparse=always sparse-image-file.img /dev/hda1 could
+	produce an invalid copy on the destination device.
+
+	* src/copy.c (copy_reg): Even with --sparse=always, try to
+	make `holes' only if the destination is a regular file.
+	Reported by Szakacsits Szabolcs.
+
+2004-03-03  Paul Eggert  <eggert@twinsun.com>
+
+	* src/nohup.c (main): Don't invoke set_cloexec_flag with
+	a file descriptor of -1.
+
+2004-03-02  Dmitry V. Levin  <ldv@altlinux.org>
+
+	* src/nohup.c: Include "cloexec.h".
+	(main): Set the copy of stderr to close on exec.
+
+2004-03-01  Paul Eggert  <eggert@twinsun.com>
+
+	* configure.ac: Include <signal.h> when checking for strsignal,
+	sys_siglist, and friends.  Problem reported by Tony Leneis in
+	<http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00136.html>.

+
+	* tests/du/deref-args, tests/du/exclude, tests/du/slash:

+	etc. are set.
+
+2004-02-23  Paul Eggert  <eggert@twinsun.com>
+
+	* NEWS: Document how chown's USER.GROUP argument is now parsed.
+
+2004-02-23  Jim Meyering  <jim@meyering.net>
+
+	* src/seq.c (usage): Remove stray space after \n in --help output.
+
+2004-02-22  Jim Meyering  <jim@meyering.net>
+
+	* src/du.c (usage): Separate -H and --si.  Say that the meaning
+	of -H will soon change to that of --dereference-args (-D).
+
+2004-02-21  Jim Meyering  <jim@meyering.net>
+
+	* src/comm.c (usage): Tell what comm does when there are no options.
+	Reword in terms of FILE1 and FILE2 rather than `left file' and
+	`right file'.  Suggestion from Dan Jacobson.
+
+2004-02-15  Paul Eggert  <eggert@twinsun.com>
+
+	Fix some POSIX-conformance bugs in expr.
+
+	* NEWS: document the following changes to src/expr.c.
+	* doc/coreutils.texi (expr invocation): Likewise.
+	Document what forms integers may take, and say "integer"
+	consistently instead of "number".  Warn about operands
+	that "expr" can misinterpret, and how to work around the
+	problem.
+	* src/expr.c (eval, eval7, eval6, eval5, eval4, eval3, eval2, eval1):
+	Accept a bool argument specifying whether to evaluate the
+	expression.  This is to allow short-circuit evaluation.  All
+	callers changed.
+	(null): Report that a string is zero even if it has
+	a form like "-0" or "00".
+	(eval1, eval): Use short-circuit evaluation for | and &.
+	(eval): Return 0 if both arguments are null or zero, instead
+	of returning the first argument.
+	* tests/expr/basic: Add some tests for the above.
+
+2004-02-17  Jim Meyering  <jim@meyering.net>
+
+	* Version 5.2.0.
+
+	`make check' from a build inside a chroot environment would fail
+	* tests/help-version: Specify an argument (`/') for df, in the
+	unusual event that there is no valid entry in /etc/mtab.
+	Likewise for id: add the -u option, so we don't get spurious
+	failures when there are no user or group names.
+	Patch by Tim Waugh.
+
+	* src/sort.c (usage) [-u]: Add punctuation so that the description in
+	the help2man-generated (line-joined) man page is more readable.
+	Reported by Tim Waugh.
+	[-T]: Add a semicolon, for the same reason.
+
+2004-02-15  Jim Meyering  <jim@meyering.net>
+
+	* Makefile.am (dist-hook): Qualify target with $(srcdir)/ prefix.
+
+2004-02-11  Jim Meyering  <jim@meyering.net>
+
+	* tests/Makefile.am.in ($(srcdir)/Makefile.am): Use more portable
+	$(srcdir)/../Makefile.am.in, rather than $<.
+	Suggestion from Michael Elizabeth Chastain.
+
+2004-02-10  Jim Meyering  <jim@meyering.net>
+
+	* config/install-sh: Make this script executable.
+	* Makefile.am (dist-hook): New target, to ensure that config/install-sh
+	is executable.  Otherwise, on systems that lack a suitable install
+	binary, `make install' would fail, because of the way this script
+	is invoked (without `$SHELL ' prefix).
+	Reported by Bob Proulx.
+
+2004-02-08  Jim Meyering  <jim@meyering.net>
+
+	* Version 5.1.3.
+
+	* tests/rm/rm5: Avoid triggering a bug in OSF/Tru64's sed
+	that would cause an unwarranted test failure.
+	* tests/rm/rm3: Likewise.
+
+2004-02-07  Jim Meyering  <jim@meyering.net>
+
+	Remove xstat function pointer member.  The way it was used was not
+	portable, since some systems (OSF V5.1, Solaris 2.5.1) provide static
+	inline `stat' and `lstat' functions, thus making the tests of
+	`xstat == lstat' in copy.c always fail.
+	* src/copy.h (struct cp_options) [xstat]: Remove member.
+	(XSTAT): New macro.
+	* src/copy.c (copy_dir): Set `.dereference' member, not .xstat.
+	(copy_internal): Use `XSTAT (x, ...)' in place of `*(x->xstat) (...)'.
+	Use `x->dereference == DEREF_NEVER' in place of `x->xstat == lstat'.
+	(valid_options): Remove now-obsolete FIXME comments.
+
+	* src/cp.c (re_protect): Use `XSTAT (x, ...)' in place of
+	`*(x->xstat) (...)'.
+	(do_copy): Declare/use local xstat rather than x->xstat.
+	(main): Remove code that set x.xstat.
+	* src/mv.c (cp_option_init): Don't initialize xstat member.
+	* src/install.c (cp_option_init): Likewise.
+
+	* Makefile.cfg (gnu_ftp_host-alpha, etc.): Un-factor .gnu.org suffix,
+	so that emit_upload_commands can use these variables, too.
+
+2004-02-06  Jim Meyering  <jim@meyering.net>
+
+	* tests/rm/deep-1: Remove `du' stack space test.
+	Apparently, `ulimit -s N' isn't portable enough.
+	This test will be restored (with a guard against losing ulimit)
+	in its own file later.
+
+	* tests/rm/deep-1 (deep): Remove progress-style diagnostics,
+	since this test doesn't take long enough to merit them.
+	Run du on $tmp (the containing dir), not $deep, the full path to leaf.
+
+	* Makefile.maint (signatures): Remove definition.
+	Now, automake's gnupload handles this.
+	(%.sig: %): Remove now-unused rule.
+	(rel-files): Use automake's $(DIST_ARCHIVES), rather than
+	`$(distdir).tar.bz2 $(distdir).tar.gz'.
+	(emit-upload-commands): Adjust to use gnupload.
+
+2004-02-05  Jim Meyering  <jim@meyering.net>
+
+	* src/system.h (ST_TIME_CMP_NS, ST_TIME_CMP): Remove definitions.
+	(ATIME_CMP, CTIME_CMP, MTIME_CMP, TIMESPEC_NS): Likewise.
+	Now, those are all defined in timespec.h.
+	Include timespec.h.
+
+	* src/date.c: Don't include timespec.h, now that system.h does it.
+
+2004-02-02  Paul Eggert  <eggert@twinsun.com>
+
+	Don't dump core if localtime returns NULL (possible on
+	hosts with 64-bit time_t and 32-bit int).
+	* src/date.c: Include "inttostr.h".
+	(batch_convert, main):
+	If time conversion fails, exit with nonzero status.
+	(show_date): Return int to report conversion failure.
+	Print the time as an int if localtime fails.
+	* src/uptime.c: Print "??" if the current clock can't
+	be converted by localtime.  This won't happen until the year
+	2*31 + 1900, but we don't want to dump core even if the current
+	clock has the wrong value.
+
+	* src/stat.c: Include "inttostr.h".
+	(human_time): Print the date/time as a number of seconds since the
+	epoch if it can't be converted by localtime.  This is better than
+	just saying "invalid", and is consistent with what "ls" does.
+	Don't dump core if the year has more than 48 digits; this isn't
+	possible on any contemporary host, but we might as well do it right.
+
+2004-01-31  Paul Eggert  <eggert@twinsun.com>
+
+	* src/stat.c (human_time): Accept time rather than
+	pointer-to-const-time parameter, for clarity.  All callers changed.
+
+2004-02-02  Jim Meyering  <jim@meyering.net>
+
+	* src/stat.c (do_stat): Remove extra trailing newline from
+	default formats.  Reported by Nelson H. F. Beebe.
+
+	Print actual fractional seconds in time stamps, not just `.00000000'.
+	* src/stat.c (human_time): Add and use new parameter, t_ns.
+	(print_stat): Update callers.
+	* src/ls.c (TIMESPEC_NS): Remove definition.
+	* src/system.h (TIMESPEC_NS): Define here, instead, now that stat.c
+	also uses this macro.
+	Nelson H. F. Beebe noticed that ls --full-time printed nonzero
+	fractional seconds for files on an XFS file system, but that stat's
+	fractional seconds were always zero.
+
+2004-01-28  Paul Eggert  <eggert@twinsun.com>
+
+	* src/seq.c (print_numbers): Use 'double' for loop index, not
+	'int', to avoid problems with integer overflow.  On almost all
+	machines 'double' works in every case where 'int' works, and
+	it works on other cases besides.
+
+2004-01-27  Jim Meyering  <jim@meyering.net>
+
+	* src/seq.c (usage): Mention that if INCREMENT is omitted,
+	it defaults to 1, even when FIRST is larger than LAST.
+	Reword so as not to exclude the possibility that INCREMENT be zero.
+
+2004-01-25  Jim Meyering  <jim@meyering.net>
+
+	* Version 5.1.2.
+
+	* Makefile.maint (signatures): Comment out definition.
+
+2004-01-23  Jim Meyering  <jim@meyering.net>
+
+	* Makefile.maint (header_regexp): Add exitfail.
+
+	* man/Makefile.am (EXTRA_DIST): Add help2man.
+	Reported by Nelson H. F. Beebe.
+
+	* man/Makefile.am (.x.1): Prefix help2man invocation with `$(PERL) --'
+	so it works on systems with Perl installed somewhere other than in
+	/usr/bin.
+
+	* src/paste.c (paste_parallel): Declare local, chr, to be of type
+	`int', not `char', since it must hold EOF.  This bug would make
+	paste infloop on some systems.  Test failures reported by
+	Nelson H. F. Beebe and Christian Krackowizer.
+
+2004-01-22  Jim Meyering  <jim@meyering.net>
+
+	* tests/rmdir/fail-perm: New file.  Test for just-fixed rmdir bug.
+	* tests/rmdir/Makefile.am (TESTS): Add fail-perm.
+
+	* man/help2man: Fix it so using --info-page='coreutils PROG' works.
+	* man/Makefile.am (.x.1): Invoke our own (tweaked) copy of help2man.
+	Use --info-page='coreutils PROG' option.
+	Now, readlink.1 refers the user to `info coreutils readlink'
+	rather than to `info readlink'.  Reported by Matt Swift.
+
+2004-01-21  Paul Eggert  <eggert@twinsun.com>
+
+	Exit status cleanup.

+	* src/chown.c (main): Removed unused local 'fail'.
+

+	Remove.
+
+	* src/chroot.c (main): Initialize exit_failure to EXIT_FAIL.

+	* src/nohup.c (main): Likewise, to NOHUP_FAILURE.
+	* src/setuidgid.c (main): Likewise, to SETUIDGID_FAILURE.
+	* src/expr.c (main): Use initialize_exit_failure rather than
+	setting exit_failure directly; this optimizes away redundant
+	assignments.
+	* src/printenv.c, src/sort.c, src/test.c, src/tty.c: Likewise.
+
+	* src/chroot.c (main): Exit with status 1 rather than 127
+	if chroot itself fails, as per documentation.
+
+	* src/chroot.c (main): Use EXIT_ENOENT and EXIT_CANNOT_INVOKE
+	rather than roll-your-own symbols or integers.

+	* src/su.c (run_shell): Likewise.
+
+	* src/cp.c (exit_status): Remove static var....

+	All uses changed.
+
+	* src/factor.c (main): Do not report a usage error simply
+	because stdin has bad numbers.
+
+	* src/id.c (problems): Now a boolean int, not a counter,
+	so that we don't have to worry about int overflow.  All uses changed.

+	* src/nohup.c (NOHUP_FOUND_BUT_CANNOT_INVOKE): Remove; all uses
+	changed to EXIT_CANNOT_INVOKE.
+
+	* src/printenv.c (PRINTENV_FAILURE): New constant.
+	(main): Exit with status PRINTENV_FAILURE, not EXIT_FAILURE, on
+	command-line syntax problems.
+
+	* src/rmdir.c (remove_parents): Don't set 'fail' to a negative number.
+	(main): Avoid integer overflow when seeing whether errors occurred.
+
+	* src/seq.c (print_numbers): Now returns void, not (zero) int.
+	All callers changed.
+	(main): Remove unused local variable 'errs'.  Always exit successfully
+	if we reach the end.
+
+	* src/setuidgid.c (SETUIDGID_FAILURE): Renamed from FAIL_STATUS,
+	for consistency with other programs here.  All uses changed.
+	(main): Use 'error' to exit rather than invoking 'exit' here.

+
+	* src/system.h (EXIT_FAIL, EXIT_CANNOT_INVOKE, EXIT_ENOENT):

+
+	* src/tty.c (TTY_FAILURE, TTY_WRITE_ERROR): New enum values;

+	(expected_failure_status_nohup): New var.
+

+	Thanks to Nelson H. F. Beebe and Paul Eggert.
+
+	* tests/touch/relative: Test only year/month/day, not hours/min/sec,
+	so as to avoid problems with systems using TAI clocks.
+	Although it's no longer necessary, set TZ=UTC0 also for the

+
+2004-01-19  Paul Eggert  <eggert@twinsun.com>
+

+	portable).  Problem reported by Christian Krackowizer.  Also, use
+	+0000 rather than +0 to specify a time zone, as the documentation
+	requires four digits.
+
+2004-01-19  Jim Meyering  <jim@meyering.net>

+	chown and chgrp now accept POSIX-mandated -H, -L, -P options and
+	use fts to perform a directory traversal when -R is specified.
+	Before, they operated on full path names, and as such would
+	encounter the PATH_MAX (often 4096) limit.
+	They are more efficient.  For example, before, chgrp -R would

+	(print_many_per_line, print_horizontal): Use it.
+	(decode_switches): Set max_idx here, not in calculate_columns.
+	(print_current_files): Don't call init_column_info; calculate_columns

+
+	csplit cleanup.
+
+	* doc/coreutils.texi (csplit invocation):
+	The regexp offset need not have a sign; POSIX requires support
+	for signless offets.
+
+	Be more careful about int widths.  For example, remove some
+	arbitrary limits by replacing 'unsigned' with 'size_t',
+	'uintmax_t', etc.  Use standard bool rather than a homegrown type.
+	* lib/Makefile.am (libfetish_a_SOURCES): Add xstrtoimax.c.
+	* src/csplit.c (FALSE, TRUE, boolean): Remove.  All uses changed
+	to <stdbool.h> usage.
+	(struct control): offset is now intmax_t, not int.
+	repeat_forever is now bool, not int.
+	(struct cstring): len is now size_t, not unsigned int.
+	(struct buffer_record): bytes_alloc, bytes_used, num_lines are now
+	size_t, not unsigned.  start_line, first_available are now
+	uintmax_t, not unsigned.
+	(hold_count, control_used): Now size_t, not unsigned.

+	create_new_buffer, get_new_buffer, load_buffer, find_line,
+	process_regexp, split_file, new_control_record, extract_regexp,
+	get_format_width, get_format_prec, max_out):
+	size args, locals, and returned values are now size_t, not unsigned
+	or int.
+	(get_first_line_in_buffer, find_line, write_to_file,
+	handle_line_error, process_line_count, regexp_error, process_regexp,
+	split_file):
+	File line, byte, and repetition counts are now uintmax_t, not unsigned.
+	(check_for_offset): Don't require a sign before the offset.
+	Use xstrtoimax to do the real work.
+	(extract_regexp): Remove harmful cast of size to unsigned.
+	256 -> 1<<CHAR_BIT, for clarity.
+	(get_format_flags): Return at most 3, to avoid worries about overflow.
+
+	(bytes_to_octal_digits): Remove.
+
+	(cleanup): Don't check whether output_stream is NULL, since
+	close_output_file does that for us.
+
+	(new_line_control, create_new_buffer): Use "foo *p = xmalloc
+	(sizeof *p);" instead of the more long-winded alternatives.
+
+	(get_new_buffer): Use O(1) algorithm for resizing a buffer
+	to a much larger size, instead of an O(N) algorithm.
+
+	(process_regexp): Use plain NULL rather than casted 0.
+
+	(make_filename): Use %u, not %d, to format unsigned file number.
+
+	(new_control_record): Use xrealloc exclusively, since it handles
+	NULL reliably.
+
+	(extract_regexp): Change misspelled word in diagnostic.
+
+	(get_format_width): Even if a minimum field width is specified,
+	allow room for enough octal digits to represent the value of
+	the maximum representible integer.  This fixes a potential
+	buffer overrun.  Calculate this room at compile-time, not
+	at run-time; this removes the need for bytes_to_octal_digits.
+	Check for overflow; this removes a FIXME.
+
+	(get_format_prec): Don't allow precision to be signed; it's
+	not ANSI.  Check for overflow.  Remove hardcoded "11" as
+	default precision; this fixes a potential buffer overrun
+	on hosts with wider size_t.
+
+	(get_format_conv_type): Change local variable to be of type
+	unsigned char, not int; this removes a potential subscript
+	violation on hosts where char is signed.
+
+	(max_out): Replace "for (;*p;)" with more-standard "while (*p)".
+	Allow "%%" in format.  Don't overflow when
+	counting lots of percents.
+
+	(usage): Default sprintf format is %02u, not %d.

+	* src/sort.c (sort_buffer_size): Omit SIZE_BOUND arg.  Compute the
+	size_bound ourselves. if an input file is a pipe and the user
+	specified a size, use that size instead of trying to guess the
+	pipe size.  This has the beneficial side effect of avoiding the
+	overhead of default_sort_size in that case.  All callers changed.
+	(sort): Remove static var size; now done by sort_buffer_size.
+
+2003-09-05  Jim Meyering  <jim@meyering.net>
+
+	* Use automake-1.7.6b and autoconf-2.57b.  Regenerate dependent files.
+
+	* tests/tail-2/tail-n0f: Wait .5 seconds for backgrounded process
+	to start, rather than just .1.  Upon failure, print unexpected state.
+
+2003-09-04  Paul Eggert  <eggert@twinsun.com>
+
+	* src/head.c (elide_tail_lines_pipe): Don't assign 0 or
+	SAFE_READ_ERROR to tmp->nbytes.
+	* src/tail.c (pipe_lines, pipe_bytes): Likewise.
+
+	* src/head.c (struct linebuffer): Change nbytes and nlines
+	from unsigned int to size_t.  unsigned int is safe (after the
+	2003-09-03 patch) but size_t is cleaner.
+	* src/tail.c (struct linebuffer, struct charbuffer): Likewise.
+	(pipe_bytes): Likewise for local variable 'i', which was 'int'.
+
+	Standardize on BUFSIZ as opposed to other macro names and values.
+	* src/head.c (BUFSIZE): Remove.  All uses changed to BUFSIZ.
+	* src/tail.c (BUFSIZ) [!defined BUFSIZ]: Remove.
+	stdio.h has always defined it,
+	and other code already assumes it's defined.
+	* src/tr.c (BUFSIZ) [!defined BUFSIZ]: Likewise.
+	(IO_BUF_SIZE): Remove; replace all uses with sizeof io_buf.
+	(io_buf): IO_BUF_SIZE -> BUFSIZ.
+
+2003-09-04  Paul Eggert  <eggert@twinsun.com>
+
+	* src/seq.c (step): Default to 1.
+	(print_numbers): Allow the output to be empty.
+	(main): The default step is 1, even if LAST < FIRST;
+	as per documentation.
+	* tests/seq/basic (onearg-2): Output should be empty.
+
+2003-09-05  Jim Meyering  <jim@meyering.net>
+
+	* Makefile.cfg (wget_files): Temporarily disable, until master
+	versions are restored to ftp.gnu.org.
+
+	* configure.ac (AM_INIT_AUTOMAKE): Specify automake-1.7.6.
+
+	Make seq's --width (-w) option work properly even when the
+	endpoint requiring the larger width is negative and smaller than
+	the other endpoint.
+	* src/seq.c (get_width_format): Include `-' in the set of bytes
+	allowed in a `simple' number (no decimal point, no exponent).
+	Reported by Patrick Mauritz.
+
+2003-09-02  Paul Eggert  <eggert@twinsun.com>
+
+	* NEWS: sort -t '\0' now uses a NUL tab.
+	sort option order no longer matters, unless POSIX requires it.
+	* src/sort.c (usage): Say "blanks" instead of "whitespace",
+	Similar fixes for many comments.
+	(TAB_DEFAULT): New constant, so that we can support NUL as
+	the field separator.
+	(tab): Now int, not char.  Initialize to TAB_DEFAULT.
+	(specify_sort_size): If multiple sizes are specified, use the largest.
+	(begfield, limfield): Support NUL tab char.
+	(set_ordering): Do not let -i override -d.
+	(main): Report an error if incompatible -o or -t options are given.
+	Report an error for "-t ''".  Allow "-t '\0'" to specify a NUL tab.
+
+2003-09-05  Jim Meyering  <jim@meyering.net>
+
+	* tests/sort/Test.pm [o2, nul-tab]: New tests for the above.

+2003-09-03  Andreas Schwab  <schwab@suse.de>
+
+	Bug report and patch here:
+	<http://mail.gnu.org/archive/html/bug-coreutils/2003-09/msg00009.html>
+	* src/tail.c (pipe_lines): Don't truncate return value from safe_read.
+	* src/head.c (elide_tail_lines_pipe): Likewise.
+
+2003-09-03  Jim Meyering  <jim@meyering.net>
+
+	* src/du.c (AUTHORS): Remove Larry McVoy's name, since the relatively
+	small amount of code from him was first moved to lib/human.c, and was
+	subsequently rewritten entirely.
+	* src/df.c (AUTHORS): Likewise.
+
+2003-08-22  Lawrence Teo  <lcteo@uncc.edu>
+
+	* src/md5sum.c (split_3): Accept the BSD format for generic
+	message digest modes.  Currently works with BSD's MD5 and SHA1
+	formats since these are the two algorithms presently used in
+	coreutils.  Updated comments to reflect this change.
+	(bsd_split_3): Updated comments.
+
+	* tests/md5sum/basic-1: New test to make sure that
+	`md5sum --check' doesn't accept the BSD SHA1 format (adapted
+	from `check-bsd' test in tests/sha1sum/basic-1).
+
+	* tests/sha1sum/basic-1 (check-bsd2, check-bsd3): New tests for
+	--check exit status and BSD SHA1 format (adapted from tests
+	in tests/md5sum/basic-1).
+
+2003-08-30  Jim Meyering  <jim@meyering.net>
+
+	* src/ln.c (do_link): Use SAME_INODE rather than open-coding it.
+
+	When source and destination arguments refer to the same file, reside
+	on a partition (e.g. VFAT) on which distinct names may refer to the
+	same directory entry (often due to variations in case), and when the
+	link count for the file is 1, mv no longer unlinks the file.  Instead,
+	it gives the expected diagnostic that the source and destination are
+	the same.  WARNING: this is an incomplete fix.  If the file happens
+	to have a link count of 2 or greater, such an erroneous mv command
+	will still unlink it.
+	Although that is not possible on vfat or umsdos, it is possible on
+	other file system types, e.g., ntfs, and hpfs.
+	* src/copy.c (same_file_ok): Invoke same_name (which might still
+	return false for names that refer to the same directory entry)
+	only if the link count is 2 or more.
+	* tests/mv/vfat: Show how to demonstrate the above problem.
+	This test is not run.
+	* tests/mv/Makefile.am (EXTRA_DIST): Add vfat.
+
+2003-08-27  Jim Meyering  <jim@meyering.net>
+
+	* src/who.c: Change meaning of -l from --lookup to --login, per POSIX.
+	who's -l option has been eliciting an unconditional warning about
+	this impending change since sh-utils-2.0.12 (April 2002).
+
+	* src/paste.c (paste_parallel): Don't output `EOF' (aka -1) as a `char'.
+	This would happen for nonempty files not ending with a newline.
+	Reported by Dan Jacobson.
+	* tests/misc/paste-no-nl: New file.  Test for above-fixed bug.
+	* tests/misc/Makefile.am (TESTS): Add paste-no-nl.
+
+	* src/stat.c (print_it): Avoid buffer overrun that would
+	occur when the user-specified format string ends with `%'.
+	Patch by Tommi Kyntola.
+	* tests/misc/stat-fmt: New file.  Test for above-fixed bug.
+	* tests/misc/Makefile.am (TESTS): Add stat-fmt.
+
+2003-08-26  Jim Meyering  <jim@meyering.net>
+
+	Apply changes from bison.
+	* GNUmakefile (SHELL): Define to `sh', if necessary.
+	Add copyright.
+	* Makefile.maint (WGETFLAGS): Define to `-C off'.
+	Update all uses of $(WGET).
+
+2003-08-22  Akim Demaille  <akim@epita.fr>
+
+	* Makefile.cfg (local-checks-to-skip): New.
+	* Makefile.maint (local-check): Rename as...
+	(local-checks-available): this.
+	(local-check): New.
+
+2003-08-26  Akim Demaille  <akim@epita.fr>
+
+	* announce-gen (print_changelog_deltas): Neutralize "<#" as
+	"<\#" to avoid magic from Gnus when posting parts of this script.
+
+2003-08-25  Jim Meyering  <jim@meyering.net>
+
+	* src/stat.c (main): Warn about use of deprecated `-l' option.
+
+2003-08-22  Jim Meyering  <jim@meyering.net>
+
+	* src/stat.c (do_stat): For link count at end of line, use %h format,
+	instead of %-5h.  The latter would make stat emit trailing spaces.
+	Reported by Dan Jacobson.
+
+2003-08-20  Jim Meyering  <jim@meyering.net>
+
+	* Makefile.am (EXTRA_DIST): Add .x-sc_space_tab .x-sc_sun_os_names
+
+2003-08-19  Jim Meyering  <jim@meyering.net>
+
+	* src/system.h: Include stdlib.h unconditionally,
+	as we're now assuming that part of hosted C89.
+
+2003-08-18  Jim Meyering  <jim@meyering.net>
+
+	* src/sys2.h (textdomain, bindtextdomain) [! ENABLE_NLS]: Define away,
+	to avoid warnings from gcc.
+
+2003-08-17  Jim Meyering  <jim@meyering.net>
+
+	Avoid unnecessary and sometimes time-consuming hostname lookups.
+	* src/who.c (print_user): Use strchr, not strrchr.
+	* src/pinky.c (print_entry): Likewise.
+	Patch by Michael Stone.
+	This fixes a typo I introduced in who-users.c on 1996-02-23.
+
+	* Makefile.maint (makefile-check): Add 0-9 to the range of characters
+	disallowed between `@...@'.
+
+2003-08-16  Paul Eggert  <eggert@twinsun.com>
+
+	* configure.ac (fu_cv_sys_truncating_statfs): Remove; now
+	done by gnulib .m4 files.
+	(jm_DUMMY_1): Require gl_READUTMP, not jm_PREREQ_READUTMP.
+	* src/sys2.h (strtoull): Remove unused declaration.
+
+2003-08-16  Jim Meyering  <jim@meyering.net>
+
+	* man/Makefile.am (.x.1): Ensure that generated PROGRAM.1 files
+	are read-only.
+
+	* src/tail.c (tail_lines): Fix a potential (but very hard to exercise)
+	race condition bug.  The bug would be triggered when tailing a file
+	with file pointer not at beginning of file, and where the file was
+	truncated to have a length of less than the initial offset at just
+	the right moment (between the two lseek calls in this function).
+
+	An invalid initial value for *read_pos would result in
+	`tail -n0 -f FILE' and `tail -c0 -f FILE' doing what amounted to a
+	busy-wait rather than sleeping between iterations.  The bug manifests
+	itself only when tailing regular files that are initially nonempty.
+	* src/tail.c (tail_bytes): Set *read_pos to new file offset after
+	each xlseek call.
+	(tail_lines): Likewise, after lseek calls.
+	Reported by Nick Estes.  See http://bugs.debian.org/205251 for details.
+	* tests/tail-2/tail-n0f: New file.  Test for above fix.
+	* tests/tail-2/Makefile.am (TESTS): Add tail-n0f.
+
+2003-08-15  Jim Meyering  <jim@meyering.net>
+

+
+2003-08-14  Paul Eggert  <eggert@twinsun.com>
+
+	* Makefile.maint (LC_ALL): Set to C.
+	* man/Makefile.am (ASSORT): New var.

+
+2003-08-11  Jim Meyering  <jim@meyering.net>
+
+	fold -s -wN would infloop for N < 8 with TABs in the input.
+	E.g., this would not terminate: printf 'a\tb' | fold -w2 -s
+	* src/fold.c (fold_file): Move contents of `else'-block
+	out of conditional so it's used also for --spaces (-s).
+	* tests/misc/fold: Test for the above fix.
+	* tests/misc/Makefile.am (TESTS): Add fold.
+
+2003-08-10  Jim Meyering  <jim@meyering.net>
+
+	* src/nice.c [!NICE_PRIORITY]: Include <sys/resource.h> after
+	system.h so the types from time.h and sys/time.h are available.
+	It appears that this is necessary for OpenBSD, NetBSD, and
+	Darwin 6.5 (MacOS 10.2.5).  Reported by Nelson Beebe.
+
+2003-08-06  Paul Eggert  <eggert@twinsun.com>
+
+	* NEWS: Add support for setting file timestamps to microsecond
+	resolution, on hosts that support this.
+	* src/copy.c, src/cp.c, src/install.c, src/touch.c: Include utimens.h.
+	* src/copy.c (copy_internal):
+	Set file timestamps with utimens, not utime.
+	* src/cp.c (re_protect): Likewise.
+	* src/install.c (change_timestamps): Likewise.
+	* src/touch.c (newtime, touch, main): Likewise.
+
+2003-08-09  Jim Meyering  <jim@meyering.net>
+
+	* Makefile.maint (sc_sun_os_names): New rule based on a regexp
+	from Paul Eggert.
+	(syntax-check-rules): Add it.
+
+	* src/tail.c (main): Tweak Solaris OS version number in comment.
+	* src/wc.c (wc): Likewise
+	* tests/tail-2/fflush: Likewise.
+
+	* src/tail.c: Add new undocumented option, --presume-input-pipe.

+
+2003-08-08  Paul Eggert  <eggert@twinsun.com>
+
+	Use new gnulib 'extensions' module.

+
+2003-08-09  Jim Meyering  <jim@meyering.net>
+
+	* tests/misc/split-fail: Reflect that `split -a 0' is now accepted.
+	For tests of obsolete behavior, don't presume that unsetting
+	_POSIX2_VERSION is equivalent to _POSIX2_VERSION=199209.
+
+2003-08-07  Paul Eggert  <eggert@twinsun.com>
+
+	* doc/coreutils.texi (split invocation):
+	Add -d or --numeric-suffixes option to 'split'.
+	From a suggestion by Jesse Kornblum.
+	* src/split.c (suffix_alphabet): New var.
+	(longopts, usage, next_file_name, main): Support -d.
+	(next_file_name, main): Allow -a0, as POSIX requires.
+	(next_file_name): Don't assume ASCII-like encoding;
+	'a' through 'z' are not contiguous in EBCDIC.
+
+2003-08-05  Paul Eggert  <eggert@twinsun.com>
+
+	Merge getline from gnulib.
+	* lib/getline.h, lib/getline.c, m4/getline.m4: Merge from gnulib.

+	New files, from gnulib.
+	* lib/getdelim2.c, lib/getdelim2.h: Remove.
+	* lib/Makefile.am (libfetish_a_SOURCES): Change getdelim2.c and

+	* m4/jm-macros.m4 (jm_MACROS): Use gl_GETNDELIM2 rather than
+	checking for getdelim.
+	(jm_CHECK_ALL_TYPES): Use gt_TYPE_SSIZE_T for ssize_t rather

+
+2003-08-04  Jim Meyering  <jim@meyering.net>
+

+
+2003-08-02  Paul Eggert  <eggert@twinsun.com>
+
+	* src/sort.c: Minor code cleanups, mostly to use more accurate

+	(min, max): Remove.  All uses changed to MIN and MAX.
+	(hard_lc_collate, hard_LC_TIME, struct buffer.eof, struct

+	(trailing_blanks): Renamed from trim_trailing_blanks.
+	Return the number of blanks to trim.  All uses changed.
+	(getmonth): Use trailing_blanks rather than open code.
+	(keycompare): Do not cast char * to unsigned char *; not needed.
+	CMP_WITH_IGNORE converts args to UCHAR, so no need to convert it
+	ourselves.
+	(compare, main): Use | rather than || to avoid jumps.
+	Replace "diff = NONZERO (alen)" with "diff = 1", since alen must
+	be nonzero there.
+	(check, first_same_file, sort, main):
+	Use bool instead of int local vars when possible.
+	(check): Merge the old 'checkfp' and 'check' into a single function,
+	that returns a boolean (true if the file was ordered).
+	All uses changed.
+	(main): Use int instead of unsigned for iterating through nsigs.
+	Rename local var "posix_pedantic" to "posixly_correct".
+
+2003-08-02  Jim Meyering  <jim@meyering.net>
+
+	* src/nice.c [!NICE_PRIORITY]: Include <time.h> before <sys/resource.h>
+	to avoid compilation error on Ultrix. Reported by Christian Krackowizer.

+
+2003-08-01  Jim Meyering  <jim@meyering.net>
+
+	* tests/shred/remove: Ensure that $? is 0 for the final `exit 0'.
+	Otherwise, with at least the /bin/sh from HPUX 10.20,
+	the trap code would end up converting that to exit 1 and thus an
+	unexpected test failure.  Reported by Christian Krackowizer.
+
+2003-07-31  Paul Eggert  <eggert@twinsun.com>

+
+2003-07-28  Paul Eggert  <eggert@twinsun.com>
+

+	* src/sort.c (sortlines_temp): Undo previous change.
+
+2003-07-28  Jim Meyering  <jim@meyering.net>
+
+	* src/sort.c (sortlines_temp): Declare local `swap' to be `int', not
+	`bool'.  Otherwise, at least one buggy compiler (alpha gcc-2.95.4)
+	would cause lines[-1 - swap] (with swap = false) to evaluate to
+	lines[4294967295].
+
+2003-07-27  Jim Meyering  <jim@meyering.net>
+
+	* tests/priv-check (my_uid): Use `!', not `^' in case pattern `[!0-9]',
+	since /bin/sh of at least NetBSD 1.6 and OpenBSD 3.2 don't accept `^'.
+
+	* src/remove.c (prompt) [! recursive]: Don't prompt about unwritable
+	directories, as required by POSIX.   Reported by Karl Berry.
+	* tests/rm/dir-no-w: New file.  Test for the above fix.

+
+	* tests/mk-script: Emit `$xx', not its expansion.
+
+2003-07-27  Paul Eggert  <eggert@twinsun.com>
+
+	This change was inspired by a similar proposal by Stepan Kasal.
+	* src/sort.c (mergelines, sortlines_temp): New functions.
+	(sortlines): Use them, to reduce the number of times that
+	we need to copy 'struct line' values.  This improved CPU
+	performance by about 30% on one 18 MB test.
+	(sort): Don't invoke sortlines unless we have 2 or more lines.
+
+2003-07-26  Stepan Kasal  <kasal@ucw.cz>
+
+	* src/sort.c (sort): Don't require two `struct line's per text line,
+	the new sort algorithm requires just 1.5.
+
+2003-07-27  Jim Meyering  <jim@meyering.net>
+

+	From Paul Eggert.
+
+2003-07-26  Jim Meyering  <jim@meyering.net>
+
+	Use only one bit per field/offset in array, not one `int'.
+	* src/cut.c (printable_field): Change type to `unsigned char'.
+	(mark_printable_field, is_printable_field): New functions.
+	Use them in place of all direct accesses of `printable_field'.
+
+	* src/expand.c (parse_tabstops): Detect overflow properly.
+	* src/cut.c (set_fields): Likewise.
+
+	* src/rm.c: Include "dirname.h".
+	(usage): Use base_name (program_name) in body of --help output.
+	This lets me...
+	* man/Makefile.am (.x.1): ...back out the kludge of 2003-07-22.
+	Idea from Brendan O'Dea, who suggested using
+	`program_name = basename (argv[0]);' everywhere --
+	can't do that, but using base_name works just fine here.
+
+	* src/Makefile.am (AM_INSTALLCHECK_STD_OPTIONS_EXEMPT): Exempt test.
+
+2003-07-24  Paul Eggert  <eggert@twinsun.com>
+
+	Fix some POSIX-compliance problems with 'test'.  This makes
+	'test' more compatible with Bash.
+
+	* NEWS, doc/coreutils.texi: Document the following.
+	* src/test.c: Include exitfail.h.
+	(TEST_FAILURE): New constant, used for exit status if 'test' fails.
+	(test-syntax_error): Use it.
+	(binary_operator): Now takes bool arg specifying whether left operand
+	is -l ARG, so that caller determines this rather than us.
+	All uses changed.
+	(term): Use posixtest to evaluate parenthesized subexpressions.
+	(unary_operator, one_argument): Remove support for -t without operand.
+	(one_argument): Take argument from argv[pos].
+	(one_argument, two_arguments, three_arguments): Advance pos.
+	All callers changed.
+	(three_arguments): Look for binary ops before "!".  Then look
+	for parenthesized one_argument expressions, instead of trusting
+	expr () to do the right thing.
+	(posixtest): Now takes number of args.  All callers changed.
+	Treat "( A B )" like "A B".
+	(main): Set exit_failure to TEST_FAILURE.  Don't depend on
+	POSIXLY_CORRECT, as we now conform to POSIX by default.
+	(main) [!LBRACKET]: Do not recognize "--help" or "--verbose" unless.
+	* tests/test/Test.pm (test_vector): Add several tests to check
+	the above.  Syntax errors now exit with status 2, not 1.
+	* man/Makefile.am (mapped_name): Use `../src/[' binary to create test.1.
+
+2003-07-26  Jim Meyering  <jim@meyering.net>
+
+	* tests/help-version: Adjust for above change in test behavior:
+	`[' exits with 2, not 1, and test doesn't accept --help or --version.
+
+	* Makefile.maint (ME): Don't use trick suggested in Make manual.
+	It doesn't work for make-3.79.1.  Reported by Christian Krackowizer.
+
+	* Makefile.maint (sc_system_h_headers): Another syntax check.
+	(syntax-check-rules): Add it to the list.
+
+	* src/pathchk.c (validate_path): Cast strlen value to `unsigned long'
+	so it matches `%ld' format even on 32-bit systems.
+
+	* src/fmt.c (flush_paragraph): Cast field width to `int' to
+	avoid warning on 64-bit systems.
+
+	* src/ls.c (sort_files): Make `func' volatile, so it can't be
+	clobbered by a `longjmp' into this function.
+
+2003-07-25  Jim Meyering  <jim@meyering.net>
+
+	* src/pathchk.c (validate_path): Use %ld format (not %d) for size_t
+	value.
+
+	* tests/misc/split-fail: Disable the --line-bytes=$_4gb test,

+	wc count field widths now are heuristically adjusted depending

+
+	Previously, wc did not align the count fields if

+	Use priv-check's require-non-root instead.
+	Update to use newer framework.

+
+	* tests/priv-check: Use `id -u' to see if we're running as root,

+	When running as root, ensure $NON_ROOT_USERNAME is valid.
+	When running as root with `require-non-root', ensure that `.'

+
+2003-07-18  Jim Meyering  <jim@meyering.net>
+
+	* tests/touch/not-owner: Update to use newer framework.
+
+	* tests/rm/fail-eperm: Use $srcdir/../priv-check, create a temporary
+	directory, and remove Perl-coded `you may not run as root' test.
+	* tests/cp/fail-perm: Use $srcdir/../priv-check, rather than
+	hard-coding something not quite equivalent.
+	Paul Jarc reported the inconsistent diagnostics.
+
+	* src/sort.c (main): Use close_stdout via atexit.
+	Now `sort --version' and `sort --help' fail, as they should
+	when their output is redirected to /dev/full.
+
+	* src/su.c (usage): Don't call close_stdout here.
+	(main): Use close_stdout via atexit.
+	Now `su --version > /dev/full' fails, as it should.
+	Somehow, the change of 2000-05-07 that purports to fix this
+	was not checked in.
+
+	* tests/help-version (--help/--version vs. /dev/full): Special-case
+	`[' to protect it from expected_failure_status-`eval'.
+
+	* src/uniq.c (writeline): Use a SPACE, not a TAB between the
+	count and the corresponding line, as required by POSIX.
+	Reported by Clement Wang.
+	* tests/uniq/Test.pm (101, 102): Update tests of -c accordingly.
+
+	* tests/expr/basic: Add tests for when exit status is 2.

+	(syntax_error): New function, exiting with status 2.  Use it
+	insteading of printing "syntax error" ourselves.
+	(main): Initialize exit_failure to EXPR_ERROR.
+	Exit with EXPR_INVALID on syntax error (too few arguments).
+	(nextarg): Use strcmp, not strcoll; strcoll might return
+	an undesirable 0, or might fail.
+	(docolon, eval4, eval3): Exit with status 3 on invalid argument type
+	or other such error.
+	(eval2): Report an error if strcoll fails in a string comparison.
+	* src/sort.c: Include "exitfail.h".
+	(main): Set exit_failure, not xalloc_exit_failure and
+	xmemcoll_exit_failure.
+	* tests/expr/basic: Invalid value exits with status 3, not 2.
+
+2003-07-16  Jim Meyering  <jim@meyering.net>
+
+	* configure.ac (AC_INIT): Use 5.0.90 as the version, rather than 5.0.2,
+	per GNU maintainer guidelines.  The next non-beta release will be 5.1.
+
+	This script would have caught at least two recent bugs:
+	those in [ and kill.
+	* tests/help-version: Revive this script.
+	It wasn't doing anything useful, since $all_programs wasn't being
+	defined by the invoking Makefile.am.
+	Reflect that nohup is no longer a script, so don't exclude it.
+	Add framework to handle the programs added since it was last run:
+	kill, stat, unlink, [, link, readlink.
+	Fix path-related problems deriving from the move of this script
+	from src/ to its present location.
+	* tests/Makefile.am (all_programs): Define.
+	(TESTS_ENVIRONMENT): Use it.
+
+	* src/kill.c (main): Fix bug introduced on 2003-05-10 (for 5.0.1)
+	whereby kill would always attempt to operate on argv[0] and fail.
+
+	* src/test.c (integer_expected_error): Improve diagnostic -- now,
+	it also matches the one from bash's builtin test.
+	(binary_operator): Add \n at end of diagnostic.
+
+	* tests/rm/fail-2eperm: Remove setuidgid-related code.  Move it to ...
+	* tests/priv-check: Move setuidgid-related and
+	NON_ROOT_USERNAME-checking code to this file.
+
+	* README: Update section on testing as `root'.
+	Suggestion from Paul Jarc.
+
+	* src/test.c (AUTHORS): Replace 3-letter usernames with the actual
+	names of authors that I just found in bash's builtins/test.def.
+
+	Running `[' with no arguments would evoke a segfault.
+	* src/test.c (main) [LBRACKET]: Move initialization of argv to
+	precede potential use via test_syntax_error.
+
+	* src/Makefile.am (AM_CPPFLAGS): Rename from `INCLUDES', to avoid
+	warning from automake -Wall.
+
+2003-07-15  Jim Meyering  <jim@meyering.net>
+
+	* Version 5.0.1.
+
+	* Makefile.maint (%.asc): Remove target first, so gpg doesn't
+	prompt us about it.
+
+	* announce-gen (print_changelog_deltas): Relax tests for matching
+	version-number line in NEWS.
+	Change the .sig suffix to .asc here, too.
+
+2003-07-14  Jim Meyering  <jim@meyering.net>
+
+	* Makefile.maint (%.asc): Renamed from %.sig.
+	Generate and use ascii-armored signatures.

+
+2003-07-13  Jim Meyering  <jim@meyering.net>
+
+	* src/nohup.c (NOHUP_FAILURE, NOHUP_FOUND_BUT_CANNOT_INVOKE): Define.

+	its own target.
+	(syntax-check-rules): This is the list of syntax-check targets.
+	(sc_unmarked_diagnostics, sc_cast_of_argument_to_free):
+	(sc_cast_of_x_alloc_return_value, sc_space_tab):
+	(sc_error_exit_success, sc_xalloc_h_in_src):  New targets.
+
+2003-07-12  Jim Meyering  <jim@meyering.net>
+
+	* configure.ac: Remove uses of OPTIONAL_BIN_ZCRIPTS and last
+	traces of the nohup script.
+
+	* src/Makefile.am (bin_SCRIPTS): Remove use of just-removed
+	$(OPTIONAL_BIN_ZCRIPTS).
+
+	* src/Makefile.am (localedir.h): Put the `2>&1' after the redirect
+	target, not before the `>'.
+
+	* src/remove.c (remove_dir): Give a diagnostic upon failed save_cwd,
+	now that that function no longer calls `error'.
+
+	* src/df.c (find_mount_point): Emit a diagnostic for each
+	failed syscall, rather than relying on caller to do that.
+	The caller couldn't do a good job, anyhow -- too many different
+	ways to fail (each with a different referent).
+	Give a diagnostic upon failed save_cwd, now that that function
+	no longer calls `error'.
+	(show_point): Don't diagnose find_mount_point's errors, now that
+	it handles them itself.
+
+	* src/df.c (find_mount_point): Don't let free clobber errno upon
+	failed chdir.
+
+	* src/sys2.h: Remove alloca-related block.
+	* src/system.h: Include <alloca.h> here, instead.
+
+	It appears that the `#pragma alloca' included via "system.h" is
+	adequate, since join.c uses alloca, yet lacked an in-file #pragma.
+	* src/copy.c, src/cp.c, src/df.c, src/install.c, src/ln.c:
+	* src/ls.c, src/mv.c, src/remove.c: Remove `#pragma alloca'.
+
+	* src/chown-core.c (change_file_owner): Do not restore any special
+	permission bits (e.g., set-user-ID, set-group-ID) that are reset
+	by chown(2) on some systems.  Suggestion and insistence :-) from
+	Michael Stone.
+
+	* tests/input-tty: Also check `test -t 1'.
+	This is necessary on linux-2.4.21.  Otherwise, the stty/basic-1
+	test would block when run in the background.
+
+2003-07-11  Jim Meyering  <jim@meyering.net>
+
+	* tests/sample-test: Also fail if cat-to-create-expected-output
+	fails.  Otherwise, if both `exp' and `out' were to end up empty
+	because of e.g., a full disk, they would mistakenly compare equal.
+
+	* src/nohup.c: New file.  Rewrite of nohup.sh in C.
+	This solves a portability problem: on at least Solaris systems,
+	when nohup.sh used the vendor /bin/sh, it would exit with status
+	of `1' rather than the required 126 or 127 upon failure to exec
+	the specified program.
+
+	* src/Makefile.am (EXTRA_SCRIPTS): Remove definition.
+	(bin_PROGRAMS): Add nohup.
+	(EXTRA_DIST): Remove nohup.sh.
+	(all_programs): Remove use of $(EXTRA_SCRIPTS).
+	* src/nohup.sh: Remove file.
+	* man/Makefile.am (nohup.1): Depend on nohup.c, rather than nohup.sh.
+
+	* tests/misc/nohup: Tests for the above.
+	* tests/misc/Makefile.am (TESTS): Add nohup.
+
+	* src/head.c (diagnose_copy_fd_failure): New function, renamed from
+	the macro, COPY_FD_DIAGNOSE.
+	(diagnose_copy_fd_failure): Enclose diagnostic in _(...).
+	(head_file): Likewise.
+
+	* src/date.c: Include "quote.h".
+	(batch_convert): Use the quote function rather than using literal `...'
+	in a diagnostic.
+
+	* src/setuidgid.c (main): Enclose diagnostic in _(...).
+	* src/fmt.c (main): Likewise.
+	* src/mknod.c (main): Likewise.
+	* src/tac.c (tac_seekable): Likewise.
+	* src/yes.c (main): Likewise.
+	* src/od.c (main): Likewise.
+	* src/install.c (change_attributes): Likewise.
+
+2003-07-10  Jim Meyering  <jim@meyering.net>
+
+	* src/head.c (usage): Use 1024*1024 in place of 1048576.
+	* src/tail.c (usage): Likewise.
+
+	* tests/rm/fail-2eperm: Now that we have setuidgid, use it in
+	place of the kludge in this test.  Suggestion from Paul Jarc.
+
+	* src/Makefile.am (noinst_PROGRAMS): Define to setuidgid.
+	* src/setuidgid.c: New program, solely for testing (not installed).
+
+	* src/chown-core.c (change_file_owner): Don't leak file descriptors
+	when dereferencing symlinks.
+
+2003-07-09  Jim Meyering  <jim@meyering.net>
+
+	* tests/du/slash: New file/test for today's lib/ftw.c fix.
+	* tests/du/Makefile.am (TESTS): Add slash
+
+	* src/tail.c (xlseek): Avoid warning about ``return without value
+	from function returning non-void''.
+
+2003-07-08  Jim Meyering  <jim@meyering.net>
+
+	* man/help2man: Update to version 1.29.
+
+	* man/help2man: Add END handler to close STDOUT and check for errors.
+
+2003-06-30  Paul Eggert  <eggert@twinsun.com>
+
+	Add support for a "[" that conforms to the GNU coding standards,
+	i.e., that does not depend on its name.
+	* src/lbracket.c: New file.
+	* README: Add "[".
+	* man/Makefile.am (programs): Ignore "[", since it doesn't have
+	a separate man page.
+	* src/Makefile.am (bin_PROGRAMS): Add "[".
+	(__SOURCES): New var.
+	* src/test.c (LBRACKET): Define to 0 if not defined.
+	(main): Use LBRACKET rather than argv[0].
+
+	* src/test.c (one_argument): Do not check for -t if POSIXLY_CORRECT.
+	Reported by Paul Jarc and Dan Jacobson.
+
+	* src/test.c (main): Do not recognize --help or --version if
+	POSIXLY_CORRECT, when invoked as "test".  Handle "[ ]" correctly.
+	Do not bother testing that margv[margc] is non-null.
+
+2003-07-04  Jim Meyering  <jim@meyering.net>
+
+	* src/who.c (print_line): Rewrite to use asprintf, in order to be
+	able to avoid emitting trailing spaces.  Reported by Dan Jacobson.
+
+	* tests/misc/head-elide-tail: Add tests of head's new --lines=-N
+	option, and perform the +1600 invocations of head IFF the envvar
+	RUN_EXPENSIVE_TESTS is set.
+
+2003-07-03  Jim Meyering  <jim@meyering.net>
+
+	* src/cp.c (do_copy): Give a better diagnostic when failing due
+	to nonexistent destination directory.  Reported by Dmitry Rutsky.
+	See http://bugs.debian.org/199730 for details.
+
+2003-06-27  Jim Meyering  <jim@meyering.net>
+
+	split's --verbose option did nothing [broken in 4.5.10 and 5.0]
+	* src/split.c (longopts): Use `1', not `0' as the value for

+
+	Test for the above fix.
+	* tests/misc/split-a: Also use --verbose and compare stderr
+	output with what we'd expect.
+
+2003-06-20  Jim Meyering  <jim@meyering.net>
+
+	* src/copy.c (copy_internal) [HAVE_STRUCT_STAT_ST_AUTHOR]:

+	From Alfred M. Szmidt.
+
+2003-06-19  Marcus Brinkmann  <marcus@gnu.org>
+

+
+	* src/ln.c (ENABLE_HARD_LINK_TO_SYMLINK_WARNING): Define to 0.
+	(do_link): Don't warn about hard link to symlink.
+
+2003-06-18  Jim Meyering  <jim@meyering.net>
+
+	* src/cut.c: Include "getdelim2.h", not "getstr.h".
+	Reflect renaming: getstr -> getdelim2.
+
+	* src/comm.c, src/join.c, src/nl.c, src/uniq.c: Reflect renaming:
+	readline -> readlinebuffer.
+
+2003-06-09  John David Anglin  <dave.anglin@nrc-cnrc.gc.ca>
+
+	* src/readlink.c: Include <sys/types.h> before system.h (because
+	the latter includes <sys/stat.h>).  Required on Ultrix 4.3.
+
+2003-06-17  Jim Meyering  <jim@meyering.net>
+
+	* src/system.h (initialize_main): Define.
+	Use it in every `main'.  Applied via this:

+	perl -ni -e '/program_name.=.argv.0/ and print "  '"$p"'\n"; print' \

+
+	* src/touch.c (touch): Call close only if necessary.
+	From Bruno Haible.
+
+	* src/wc.c (usage): Correct wording: wc prints counts in the order
+	`newline, word, byte'.  Reported by Keith M. Briggs.
+	* man/wc.x: Fix it here, too.  And change `lines' to `newlines'.
+
+2003-06-10  Jim Meyering  <jim@meyering.net>
+

+
+	Avoid unnecessary copying of environment.
+	* src/env.c (main): Rather than clearing the environment and --
+	unless told to ignore environment -- copying all settings from

+
+2003-06-02  Jim Meyering  <jim@meyering.net>

+
+	* src/dd.c (usage): Don't use `,' as the thousands separator
+	in e.g. 1,000,000 and 1,048,576.  Instead, do this:

+
+	* src/uniq.c (enum output_mode, mode): Remove, replacing with:

+	New vars.  All uses of "mode" changed to use these variables,
+	which are not mutually exclusive as "mode" was.
+	(writeline): New arg "match", used to control whether to

+2003-05-14  Jim Meyering  <jim@meyering.net>
+

+
+	* src/readlink.c (main): Set program_name before first use.
+	Remove that (redundant) first use.
+	Don't exit successfully just because --verbose was specified.
+	Pass 0, not EXIT_SUCCESS, as first argument to error; when that

+
+	* src/uname.c (main): When failing due to too many arguments, also say
+	that, rather than just "Try `uname --help' for more information.".
+	* src/comm.c (main): Likewise, but for too few arguments.

+
+2003-05-09  Jim Meyering  <jim@meyering.net>

+
+2003-05-04  Jim Meyering  <jim@meyering.net>
+
+	* tests/head/Test.pm: Remove tests of --bytes=-N; using that framework
+	caused the addition of thousands of small files to the tar archive.
+	* tests/misc/head-elide-tail: New file.  Add them here instead.
+	* tests/misc/Makefile.am (TESTS): Add head-elide-tail.
+
+2003-05-04  Paul Eggert  <eggert@twinsun.com>
+
+	* src/remove.c (HAVE_WORKING_READDIR): Define to 0 if not defined.
+	(IF_READDIR_NEEDS_REWINDDIR): Remove.
+	(remove_cwd_entries): Rewrite to avoid IF_READDIR_NEEDS_REWINDDIR,
+	which was a bit weird because it couldn't be emulated by a function.
+
+2003-05-03  Jim Meyering  <jim@meyering.net>
+
+	Extend head to accept --lines=-N (--bytes=-N) and to print all
+	but the N lines (bytes) at the end of the file.
+	* src/head.c: Include full-write.h, full-read.h, inttostr.h, quote.h.
+	Use quote() in diagnostics, rather than literal `' marks.
+	(copy_fd, elide_tail_bytes_pipe, elide_tail_bytes_file):
+	New functions.
+	(elide_tail_lines_pipe, elide_tail_lines_file): New functions.
+	(head_file): Reorganize so as to call head from only one place.
+	(main): Likewise, for head_file.
+	Handle new, undocumented option, --presume-input-pipe.
+	Handle negative line and byte counts.
+	* tests/head/Test.pm: Add lots of tests to exercise --bytes=-N.
+
+	* tests/du/8gb: Skip test if the file system of `.' doesn't support
+	sparse files -- otherwise it'd create a file of size 8GB.
+
+2003-05-02  Jim Meyering  <jim@meyering.net>
+
+	* src/fmt.c (usage): Don't mention obsolescent -WIDTH option.
+	Instead explain about `-' and standard input.
+	(main): Give a proper diagnostic for e.g., `fmt -c -72'.
+	Reported by Keith Thompson.
+	* tests/fmt/basic: Add test for the above fix.
+
+	* src/fmt.c: Include "quote.h".
+	Use quote() in diagnostics, rather than literal `' marks.
+	(main): Exit nonzero when unable to open an input file.
+	* tests/fmt/basic: Add test for the above fix.
+
+	* src/fmt.c (main): Diagnose invalid suffix on obsolescent width
+	specifications like `-72x'.
+	* tests/fmt/basic: Add test for the above fix.
+
+	Work around nasty readdir bug on Darwin6.5.
+	* src/remove.c (IF_READDIR_NEEDS_REWINDDIR): Define.
+	[! HAVE_WORKING_READDIR] (remove_cwd_entries): If readdir has just
+	returned NULL and there has been at least one successful unlink or
+	rmdir call since the opendir or previous rewinddir, then call
+	rewinddir and reiterate the loop.
+
+	Factor out common code.
+	* src/remove.c (readdir_ignoring_dotdirs): New function.
+	(is_empty_dir): Use it here.
+	(remove_cwd_entries): Use it here.
+
+2003-05-01  Jim Meyering  <jim@meyering.net>
+
+	* tests/rm/r-3: Create 500 rather than just 300 files.
+	There's a bug in Darwin6.5's readdir that shows up only with
+	338 or more files.
+	Fix a bug in this test: `cd $pwd' (not to `..'), now that $tmp
+	has two components.
+
+	* src/tail.c:
+	Change type of n_units, n_bytes, n_lines to be `uintmax_t'.
+	(dump_remainder): Move two declarations `down' into the scope
+	where they are used.
+	(xlseek): Return the resulting offset.
+	(file_lines): Rename parameter, file_length, to end_pos.
+	(pipe_lines): Don't coerce safe_read return value to `int'.
+	Adapt tests accordingly.
+	(pipe_bytes) [struct charbuffer] (nbytes): Change type from `int'
+	to `unsigned int'.
+	Change type of `total_bytes' from `int' to `size_t',
+	since the former wouldn't always be wide enough.
+	Don't coerce safe_read return value to `int',
+	and adapt tests accordingly.
+	Now that testing for a read error no longer involves
+	using `tmp', handle that case *after* freeing `tmp'.
+	(start_bytes): Clean up.
+	(tail_bytes): Now that `n_bytes' may be larger than
+	OFF_T_MAX, test for that condition and, if it's true, don't
+	use lseek optimizations.
+	(parse_options): Don't fail just because N_UNITS is larger than
+	the maximum size of a file -- tail may be applied to an input
+	stream (e.g., a pipe) with more data than that.
+
+	* Makefile.maint (syntax-check): Rename from alloc-check.
+	Also check for SPACE-TAB sequences.
+	Also check for malloc/calloc/realloc casts.
+
+2003-05-01  Jim Meyering  <jim@meyering.net>

+
+2003-04-28  Jim Meyering  <jim@meyering.net>

+	make the now-more-picky tsort fail.
+
+2003-04-24  Jim Meyering  <jim@meyering.net>
+
+	* src/tsort.c (tsort): Remove unnecessary test of have_read_stdin.
+	(main): Minor syntactic clean-up.
+
+	* src/tsort.c (tsort): Fail if the input contains an odd number of
+	tokens.  Reported by junkio@cox.net.
+
+	* tests/tsort/basic-1: Test for the above fix.
+
+2003-04-21  Jim Meyering  <jim@meyering.net>
+
+	* tests/misc/printf: Add tests for the printf fixes below.
+
+	* Makefile.cfg (cvs_files): Add $(srcdir)/config/depcomp to the list.
+
+2003-04-20  Paul Eggert  <eggert@twinsun.com>
+
+	Fix printf POSIX compatibility bug reported by Ben Harris in
+	<http://mail.gnu.org/archive/html/bug-coreutils/2003-04/msg00070.html>.
+	* doc/coreutils.texi (printf invocation): It's \NNN in the format,
+	\0NNN in the %b operand.
+	* src/printf.c (usage): Likewise.
+	(print_esc): New arg OCTAL0 to specify whether \0NNN or \NNN
+	is desired.  All uses changed.  Behave like Bash printf if %b
+	operand uses \NNN where the initial N is not 0.

+
+	* src/remove.c (is_empty_dir): Don't closedir (NULL).
+
+2003-04-12  Jim Meyering  <jim@meyering.net>
+
+	Giving nl an invalid STYLE argument (in --header-numbering=STYLE (-h),
+	--body-numbering=STYLE (-b), or --footer-numbering=STYLE (-f)) or
+	FORMAT (--number-format=FORMAT (-n)) would not give a useful diagnostic.
+	* src/nl.c (main): Fix those problems and remove literal quote marks
+	(e.g., "`%s'") from format string; instead use "%s" in each format
+	string and `quote (optarg)' as the corresponding argument.
+	Also, diagnose all invalid command line options before failing.
+
+	* src/nl.c (proc_text): Fix a bug that would make nl output extra
+	newlines in some cases.  Details here: http://bugs.debian.org/177256.
+	This bug was introduced on 2001-11-10 for textutils-2.0.17.
+	* tests/misc/nl: Add test for the above-fixed bug.
+
+	* tests/misc/readlink: New file.  Test the --canonicalize option.

+
+	* src/ls.c: Include <stdlib.h> unconditionally.
+
+	* Makefile.maint (xalloc-check): Rename from header-check.
+
+	* src/yes.c: Include error.h after system.h, not before.
+
+	Clean up.

+
+2003-04-10  Jim Meyering  <jim@meyering.net>
+
+	* src/stty.c (wrapf): Declare with format attribute.
+
+	The S_MAGIC_... names shouldn't be maintained in two places (prior
+	to this change, one would have to keep stat.c and fs.h in sync).
+	This change makes it so those names and the corresponding
+	hexadecimal constants all reside in stat.c.  fs.h is now generated.
+	* src/Makefile.am (fs.h): New rule to generate fs.h from stat.c.
+	(BUILT_SOURCES): Add fs.h, now that it's generated.
+	(EXTRA_DIST): Add extract-magic.
+	* src/extract-magic: New script to extract fs.h definitions from stat.c.
+	* src/stat.c (human_fstype) [__linux__]: Append each hex constant from
+	fs.h in a comment after the corresponding `case S_MAGIC_...:' statement.
+
+	* tests/tail-2/big-4gb: Skip this test (don't fail) if creating a
+	file with nominal length > 4GB fails.  Reported by Michael Deutschmann.
+
+	* man/unexpand.x: Add `SEE ALSO' reference to expand.
+	* man/expand.x: Add `SEE ALSO' reference to unexpand.
+	Suggestion from Dan Jacobson.

+2003-04-10  Maciej W. Rozycki  <macro@ds2.pg.gda.pl>
+
+	* src/fs.h (S_MAGIC_DEVPTS): New magic for Linux's devpts.

+	(main): Check for overflow in obsolescent line count option.
+
+2003-04-09  Jim Meyering  <jim@meyering.net>
+
+	* tests/misc/split-fail: Add a new test for the above fix.
+
+	* src/split.c (bytes_split): Use size_t temporary (rather than
+	uintmax_t original) in remaining computations.  From Paul Eggert.
+
+	Handle command line option arguments larger than 2^31.
+	This allows e.g., splitting into files of size 2GB and larger,
+	and running split --lines=N with N=2^31 or more.
+	But for --line-bytes=N, the restriction that N <= SIZE_MAX
+	remains (for now), due to the way it is implemented.
+
+	* src/split.c: Include "inttostr.h".
+	(bytes_split, lines_split, line_bytes_split, main):
+	Use uintmax_t, not size_t, for file sizes.
+	(main): Give a better diagnostic for option arguments == 0.
+	Use umaxtostr to print file sizes.

+
+	* src/Makefile.am (PERL): Remove unnecessary definition.
+
+	Because of inappropriate (but POSIX-mandated) behavior of rename,
+	`mv a b' would not remove `a' in some unusual cases.  Work around

+
+	* src/stat.c: Don't include <sys/sysmacros.h>.
+	That is already done via system.h.  Otherwise, the multiple
+	inclusion would evoke redefinition warnings from Cray's /bin/cc,
+	aka Cray Standard C Version 4.0.3  (057126) Mar 22 2003  22:02:28.

+
+2003-03-19  Jim Meyering  <jim@meyering.net>
+
+	* man/Makefile.am (.x.1): Use $(LN_S) instead of 'ln -s',
+	because the DJGPP 2.03 port of 'ln -s' doesn't work.
+	Include $(EXEEXT) in program names.
+	Since $(LN_S) may degenerate to `cp -p', be careful
+	to invoke it from the destination directory.
+	Mostly from Richard Dawe.
+	* configure.ac: Use AC_PROG_LN_S.
+
+	* tests/mv/part-symlink: Unset CDPATH.  Otherwise, having the
+	CDPATH shell variable set could cause this test to fail.
+	Reported by Karl Berry.
+
+2003-03-18  Jim Meyering  <jim@meyering.net>
+
+	* src/fmt.c [struct Word] (paren, period, punct, final): Change the

+	Patch by Petter Reinholdtsen.  Also reported by Mike Jetzer.
+
+2003-03-17  Richard Dawe  <rich@phekda.freeserve.co.uk>
+
+	* configure.ac: Include $(EXEEXT) in OPTIONAL_BIN_PROGS'
+	program names, since automake only adds $(EXEEXT) to programs
+	in its *_PROGRAMS.
+
+2003-03-16  Jim Meyering  <jim@meyering.net>
+
+	* src/remove.c (rm): Put two local variables in static storage,
+	so they can't be clobbered by the potential longjmp.
+
+2003-03-15  Jim Meyering  <jim@meyering.net>
+
+	* Makefile.cfg (gnu_rel_host): Fix code to match the comment

+	as an alpha release.  Reported by Richard A Downing.
+	(gnu_rel_host): Define in terms of $(RELEASE_TYPE) instead.
+
+2003-03-14  Jim Meyering  <jim@meyering.net>
+
+	* src/ansi2knr.c: Remove no-longer-used file.
+	* src/ansi2knr.1: Likewise.
+
+	* Makefile.maint (prev_version_file): Don't use ?= for this particular
+	assignment, since it causes trouble with old versions of GNU make
+	(e.g. 3.76.1).  The other uses of `?=' are inoffensive.  Details here.
+	http://mail.gnu.org/archive/html/bug-coreutils/2003-03/msg00028.html
+	Patch from Alexandre Duret-Lutz.
+
+	* Use patched automake-1.7.3.  Regenerate Makefile.in files in
+	subdirectories so that each includes a definition of ACLOCAL_M4.
+
+	* announce-gen (main): Label the compressed source URLs.
+
+	* Version 4.5.10.
+
+	* tests/du/slink: Relax the test for the `local'ness of a file system,
+	so that now it works also for tmpfs.
+
+	* tests/du/hard-link: Transform output from first du, so that this
+	test doesn't fail on file systems like tmpfs that order directory
+	entries differently.
+
+2003-03-13  Jim Meyering  <jim@meyering.net>
+
+	* tests/du/8gb: Work around what appears to be an NFS failure that
+	would make this test fail on some systems.
+
+2003-03-11  Jim Meyering  <jim@meyering.net>
+
+	* tests/du/basic: Make the test file exactly 4k bytes long.
+
+	* src/split.c (longopts): Don't hard-code `2' here.
+	Instead, just specify `&verbose', and ...
+	(main): ... remove the `case 2:' block for --verbose.
+
+	* tests/du/basic: Make the test file larger than 64 bytes, so that
+	we don't immediately disqualify file systems (e.g., NetApp) on which
+	smaller files take up zero disk blocks.  Reported by Vin Shelton.
+
+2003-03-10  Jim Meyering  <jim@meyering.net>
+
+	Don't segfault for a negative field width or precision in format string.
+	Note that this is just a stopgap fix.  The longer term solution may
+	involve adapting bash's builtins/printf.def.
+
+	* src/printf.c: (UNSPECIFIED): Define.
+	(print_direc): Use the special value, UNSPECIFIED, to indicate
+	that field_width or precision has not been specified.
+	(print_formatted): Fail if field_width or precision is the
+	special value, UNSPECIFIED.
+	Reported by Oliver Kiddle <okiddle@yahoo.co.uk>
+
+	* src/sys2.h (INT_MIN): Define, if necessary.
+	* tests/misc/printf: Add a test for the above-fixed bug.
+
+2003-03-09  Jim Meyering  <jim@meyering.net>
+
+	* src/remove.c (AD_stack_pop): Cast sizeof... to int before
+	changing its sign.  This avoids a warning from gcc on 64-bit systems.
+	Reported by Bob Proulx.
+	(pop_dir): Reverse order of sign change and cast, to be consistent
+	with the above.
+
+2003-03-08  Jim Meyering  <jim@meyering.net>
+
+	* tests/Makefile.am (evar-check): Check for POSIXLY_CORRECT not as a
+	shell variable, but only in the environment.  With /bin/sh->bash, the
+	shell variable is set to `y', and that would cause a spurious warning.
+	Reported by Bob Proulx.
+
+	* tests/Makefile.am (check-root): Remove touch/fifo.
+	It doesn't appear to have to be run as root.
+
+	* tests/rm/fail-2eperm: Rather than simply using the first non-root
+	user name, make sure that the selected user name has a usable shell.
+	Reported by Paul Jarc.
+
+	Before, when using shred on a device, one had to specify --exact,
+	or be careful to choose a size that would not be rounded up and
+	exceed the maximum value;  that could result in a failure of
+	the final write.
+	* src/shred.c (do_wipefd): --exact is now the default for non-regular
+	files.  Suggestion from Ben Elliston.
+	(usage): Say it.
+
+	* tests/misc/tty-eof: Require at least version 1.11 of Expect.pm.
+	Old versions of Expect.pm (e.g., 1.07) lack the log_user function.
+	Patch by Bob Proulx.
+
+	* src/Makefile.am (check-misc): Check for use of `defined' in
+	#define directives.
+	Change to $(srcdir) before running grep.
+
+	* src/sleep.c: Remove now-unused #include and #define directives.
+
+	* src/du.c (process_file): If a file's size is not being counted
+	e.g., because it's a hard link to a file we've already counted,
+	then don't print a line for it.
+
+	* tests/du/hard-link: New test for the above-fixed bug.
+	* tests/du/Makefile.am (TESTS): Add hard-link.
+
+	`du -S' didn't work
+	* src/du.c: Revert most of the `reorganization' change of 2003-02-20,
+	and make the two-array approach work.
+
+	* tests/du/basic: Correct/add tests for the above fix.
+	Set LC_ALL, etc., now that we use sort.
+	Check the block/size of a small file, too.
+	Correct expected results for simple dir1/dir2/file case.
+	Add another test of du -S.
+
+2003-03-07  John David Anglin  <dave.anglin@nrc-cnrc.gc.ca>
+
+	Avoid build failure with gcc on hppa1.1-hp-hpux10.20 (see GCC PR
+	middle-end/9986).  As one of GCC's optimizations, it transforms a
+	fputs_unlocked call to a fputc_unlocked call when the string is
+	one character long.  However, hpux doesn't have fputc_unlocked.
+
+	* expr.c (usage): Use putchar, not fputs, to output a single character.
+	* ls.c (dired_dump_obstack): Likewise.
+	* ptx.c (output_one_tex_line, output_one_dumb_line): Likewise.
+	* stat.c (print_it): Likewise.
+
+2003-03-07  Jim Meyering  <jim@meyering.net>
+
+	* src/cp.c: Remove everything associated with mmap-stack.c.
+	This reverts the two changes of 2003-02-21.
+	* src/du.c: Remove everything associated with mmap-stack.c.
+	This reverts the change of 2003-02-19.
+
+2003-03-06  Jim Meyering  <jim@meyering.net>
+
+	* tests/cp/same-file: Unset CDPATH.  Otherwise, having the
+	CDPATH shell variable set could cause this test to fail.
+	Reported by Karl Berry.
+
+2003-03-05  Jim Meyering  <jim@meyering.net>
+
+	* Version 4.5.9.
+
+	* src/printf.c (print_esc): Remove pointless comparison of unsigned
+	integer with zero, to avoid a warning from Intel's ecc.
+	Reported by Nelson Beebe.
+
+	* src/du.c (process_file): Sizes must all be of type uintmax_t.
+	Otherwise, for files or totals that are too big, numbers would
+	be truncated.  Patch mostly by Michael Stone.
+	Reported by Ingo Saitz as Debian bug #183210.
+
+	* tests/du/8gb: New test for the above-fixed bug.
+	* tests/du/Makefile.am (TESTS): Add 8gb.
+
+	* src/du.c (MAX_N_DESCRIPTORS): Use 3 * UTILS_OPEN_MAX / 4
+	rather than UTILS_OPEN_MAX - 10.
+
+2003-03-04  Jim Meyering  <jim@meyering.net>
+
+	* README: Refer new feature discussion to bug-coreutils@gnu.org,
+	rather than bug-gnu-utils, now that the former is better known.
+	Suggestion from Göran Uddeborg.
+
+	* src/stat.c (usage): Capitalize consistently.
+	Reported by Göran Uddeborg.
+
+	* Makefile.maint (rel-files): Include $(signatures), so that
+	those files are also copied into $(release_archive_dir).
+
+	* src/df.c (find_mount_point): Call error here, now that restore_cwd
+	no longer does it.
+	* src/remove.c (AD_pop_and_chdir): Likewise.
+
+	* tests/Makefile.am (check-root): Add fail-2eperm.
+
+2003-03-03  Jim Meyering  <jim@meyering.net>
+
+	* src/remove.c (remove_cwd_entries): Include the full filename of
+	the offending file, not just the basename.
+
+	* tests/misc/tty-eof: Set $ME properly.
+
+	* Makefile.maint (THIS_VERSION_REGEXP, PREV_VERSION_REGEXP):
+	Remove now-unused variables.
+	(tag-prev-version, prev-cvs-tag): Likewise.
+
+	* src/remove.c (remove_cwd_entries) [!ROOT_CAN_UNLINK_DIRS]: Give an
+	accurate diagnostic when failing to remove a file owned by some other
+	user.  Reported by Ivo Timmermans via Michael Stone.
+	This fixes Debian bug# 178471.
+
+	* tests/rm/Makefile.am (TESTS): Add fail-2eperm.
+	* tests/rm/fail-2eperm: New test, for the above-fixed bug.
+	Based on a report from Ivo Timmermans.
+
+2003-03-02  Jim Meyering  <jim@meyering.net>
+
+	* src/copy.c (copy_internal) [un_backup]: When recovering from a
+	failure to create a hard link, do not remove the entry associating
+	the source dev/ino with the destination file name.
+	* tests/mv/Makefile.am (TESTS): Add hard-3.
+	* tests/mv/hard-3: New test, for the above-fixed bug.
+	Inspired by a report from Iida Yosiaki.
+
+2003-03-01  Jim Meyering  <jim@meyering.net>
+
+	* src/df.c (print_header): Don't embed spaces in a separate `Type'
+	header string.  Instead, put `Filesystem' and `Type' headers in the
+	same string, so translators can use horizontal space as needed.
+	Reported by Jean Charles Delepine.
+
+2003-02-28  Jim Meyering  <jim@meyering.net>
+
+	* src/copy.c (copy_internal): When link fails because of an
+	existing destination file, unlink that file and try again.
+	Reported by Iida Yosiaki.
+
+	* tests/mv/Makefile.am (TESTS): Add hard-2.
+	* tests/mv/hard-2: New test for the above-fixed bug.
+	Based on a test case from Iida Yosiaki.
+
+2003-02-26  Jim Meyering  <jim@meyering.net>
+
+	* tests/du/basic: Don't test du's -b option here.  Directory byte
+	counts are smaller (512 rather than 4096) on at least OSF/1 5.1
+	and IBM AIX 4.2.  Reported by Nelson Beebe.
+
+2003-02-25  Jim Meyering  <jim@meyering.net>
+
+	* Makefile.maint (announcement): Now that ChangeLog entries
+	are output by announce-gen, don't do it here.
+	* announce-gen (print_changelog_deltas): New function.
+	(main): Use it.
+
+2003-02-22  Jim Meyering  <jim@meyering.net>
+
+	* announce-gen: New option: --release-type=TYPE
+	* Makefile.maint (beta, major): New targets.  Remove `release'.
+	Put them all together on a line.
+	Pass the release type (via RELEASE_TYPE envvar) to the MAKE
+	invocation of `announcement'.
+	(announcement): Invoke announce-gen with --release-type=$RELEASE_TYPE.
+
+	* announce-gen: New option: --news=NEWS_FILE.
+	Extract NEWS entries here, not via rules in Makefile.maint.
+	* Makefile.maint (announcement): Now that NEWS entries are
+	extracted by announce-gen, don't do it here.
+	(news-r1, news-r2): Remove now-unused definitions.
+
+2003-02-21  Jim Meyering  <jim@meyering.net>
+
+	* Version 4.5.8.
+
+	Merge in changes from autoconf's version of this file.
+	* Makefile.maint (www-gnu): Define.
+	(standards.texi-url_prefix): Use $(www-gnu).
+	(make-stds.texi-url_prefix): Likewise.
+
+	* src/cp.c: Include "mmap-stack.h".
+	(main): Invoke `run' through a macro that (when possible) runs it
+	with a large, mmap'd stack.
+
+	* src/cp.c (run): New function, preparing for the above.
+	Exit from this function, not from main
+	(main): Call run.
+
+	* src/du.c: New option: --apparent-size.
+	(enum) [APPARENT_SIZE_OPTION]: New member.
+	(long_options): Add it.
+	(usage): Describe it.
+	(main): Handle it.
+	['b']: Set apparent_size.
+	David Eisner reported that the behavior of --bytes had changed.
+	Paul Eggert proposed the use of a new option, --apparent-size.
+
+	* src/du.c (apparent_size): New global.
+	(print_only_size): Reflect the fact that we're printing byte counts,
+	not ST_NBLOCKSIZE-byte-block counts.
+	(print_size): Call print_only_size rather than duplicating its code.
+	(process_file): Accumulate byte counts, rather than block counts.
+
+	* src/du.c (process_file): Always reset size_to_propagate_to_parent
+	for --separate-dirs (-S).
+
+2003-02-20  Jim Meyering  <jim@meyering.net>
+
+	* Use automake-1.7.3.  Regenerate dependent files.
+
+	* src/stat.c (print_stat): New format: %B (to print ST_NBLOCKSIZE).
+	This makes %b (number of ST_NBLOCKSIZE-byte blocks) more useful.
+	(usage) [%B]: Describe it.
+	[%b]: Refer to %B.
+
+	* src/du.c (process_file): Reorganize the code to use only
+	one `sum' array, and change how -S works back to the way it was
+	before 2003-01-31.  Patch by Bruno Haible.
+
+	* tests/du/basic: New test.
+	* tests/du/Makefile.am (TESTS): Add basic.
+
+	* tests/envvar-check: Add checks for the following:
+	BLOCK_SIZE, DU_BLOCK_SIZE, DF_BLOCK_SIZE, LS_BLOCK_SIZE.
+
+	* tests/Makefile.am: Rename phony target envvar-check to evar-check
+	so as not to conflict with the distributed file by the same name.
+
+	* src/du.c (process_file): Set info->skip before any possible return.
+
+	Report correct usage for directories, not 0.
+	* src/du.c (process_file): Return for `file_type == FTW_DPRE'
+	_before_ recording the dev/ino of a directory.
+	Reported by Bruno Haible.
+
+	Now, df always displays the device file name corresponding to the
+	listed mount point under `Filesystem'.  Before, for an unmounted
+	block- or character-special file argument, it would display the
+	command-line argument instead.
+	* src/df.c (show_disk): Return a value indicating whether
+	there was a match.  Don't try to find a mount point here.
+	(show_entry): If show_disk doesn't find a match, call show_point.

+	* src/du.c: Include "mmap-stack.h".
+	(du_files): Add prototype with ATTRIBUTE_NORETURN.
+	Exit from this function, not from...
+	(main): ...here.
+	Instead, if possible, invoke du_files through a macro that
+	runs it with a large, mmap'd stack.
+
+	* src/join.c (usage): Change wording in --help output:
+	use FILENUM instead of `SIDE' and say what FILENUM means.
+	Reported by Bernhard Gabler.
+
+	* src/df.c (print_header): Rather than using a hard-coded literal
+	string of spaces matching the length of the English `...Type' header,
+	output the right number of spaces to match the selected translation.
+	Reported by Yann Dirson and Jean Charles Delepine as Debian bug 131113.
+
+	* src/split.c (bytes_split): Remove unnecessary `else' after break.
+	(lines_split): Likewise.  and correct misleading indentation.
+
+	* src/split.c: Include "full-read.h".
+	(bytes_split, lines_split, line_bytes_split): Use full_read,
+	not safe_read.   The way split was using the latter, a short read
+	could cause split to terminate before EOF.
+
+	* tests/misc/tty-eof: Test all programs that can read stdin,
+	requiring no arguments and that write to standard output.
+
+	* tests/misc/tty-eof: New file.  Renamed from ...

+	* tests/misc/Makefile.am (TESTS): Reflect renaming.

+	cksum would perform an extra read after encountering EOF
+	* src/cksum.c (cksum): Exit the loop upon EOF, too.
+	Patch by Michael Bacarella.
+
+	Test for the bug fixed today in cksum, md5sum, and sha1sum.

+2003-02-12  Jim Meyering  <jim@meyering.net>
+
+	* src/pathchk.c (portable_chars_only): Remove unnecessary `const'

+
+2003-02-10  Jim Meyering  <jim@meyering.net>
+
+	* src/test.c: Don't include group-member.h.
+	Include euidaccess.h.
+	(eaccess): Rewrite function to set the real uid and gid temporarily
+	to the effective uid and gid, then invoke 'access', and then set the
+	real uid and gid back.  On systems that lack setreuid or setregid,
+	fall back on the kludges in euidaccess.  Before, it would not work
+	for e.g., files with ACLs, files that were marked immutable,
+	or on file systems mounted read-only.  Nelson Beebe raised the issue.
+	Paul Eggert suggested the new implementation.

+2003-02-09  Jim Meyering  <jim@meyering.net>
+

+
+	* Version 4.5.7.

+
+	`df /dev/block-or-char-device-file--not-mounted' now reports

+	Before, it would leave the `Mounted on' field blank.
+	* src/df.c (show_disk): Move function to precede find_mount_point.
+	(show_disk): Add parameter: STATP.
+	If we don't find a matching device name, then resort to calling

+	(print_stat): Arrange so that field width and an alignment specifier
+	are honored for the %A, %F, %x, %y, and %z formats.
+	[%F]: Use file_type; this gives slightly different file type strings,
+	e.g., `directory' instead of `Directory' and `regular file' or
+	`regular empty file' instead of `Regular file'.
+	Prompted by a report from Richard Dawe that the uses of
+	S_IFSOCK and S_IFIFO in print_human_time were not portable
+	to systems using e.g., DJGPP.
+
+2003-01-31  Richard Dawe  <rich@phekda.freeserve.co.uk>
+
+	* src/stat.c (print_stat): Use S_ISLNK rather than an explicit
+	test using S_IFMT and S_IFLNK.  S_IFLNK may not be defined.
+
+2003-01-31  Jim Meyering  <jim@meyering.net>
+
+	* src/du.c (main): Upon processing an invalid option or an invalid
+	--exclude-from or --max-depth option argument, don't exit right away,
+	in case there are others.  Rather record the failure and exit after

+
+2003-01-27  Jim Meyering  <jim@meyering.net>
+
+	* src/ls.c (decode_switches): If `dired' is set without
+	`format == long_format', then silently reset dired.  This doesn't
+	change the behavior of ls (all prior uses of dired were protected
+	by `&& format == long_format'), and lets us...
+	(DIRED_INDENT): ... remove the `format == long_format' conjunct.
+	(PUSH_CURRENT_DIRED_POS): Likewise.
+	(main): Likewise.
+
+2003-01-22  Jim Meyering  <jim@meyering.net>

+
+	* src/remove.c (remove_entry) [ROOT_CAN_UNLINK_DIRS
+	&& HAVE_STRUCT_DIRENT_D_TYPE]: If a file has d_type == DT_UNKNOWN
+	it may still be a directory -- or not (e.g., with FreeBSD on an
+	NFS-mounted file system), so resort to calling lstat to find out.
+	Based on a patch by Michael van Elst.
+
+	* tests/cp/same-file: Don't assume that the file owner username
+	length is less than 9 in ls output: instead, omit that field
+	altogether.  Reported by, and suggested fix from, Ferdinand.
+
+2003-01-20  Jim Meyering  <jim@meyering.net>
+
+	* tests/date/Test.pm (wide-fmt): New test to demonstrate that

+
+2003-01-19  Jim Meyering  <jim@meyering.net>
+

+	* src/ls.c (Dereference_symlink) [DEREF_COMMAND_LINE_SYMLINK_TO_DIR]:
+	New member.
+	(enum) [DEREFERENCE_COMMAND_LINE_SYMLINK_TO_DIR_OPTION]: New member.
+	(long_options): Add option --dereference-command-line-symlink-to-dir.
+	(main): Make DEREF_COMMAND_LINE_SYMLINK_TO_DIR be the default,
+	rather than DEREF_COMMAND_LINE_ARGUMENTS, when none of the
+	-d, -F, -l options is specified.
+	(decode_switches): Handle --dereference-command-line-symlink-to-dir.
+	(gobble_file): Honor DEREF_COMMAND_LINE_SYMLINK_TO_DIR.
+	Change --dereference-command-line (-H) to dereference *all*
+	command line arguments, including broken symlinks.
+
+2003-01-15  Paul Eggert  <eggert@twinsun.com>
+
+	Change ls -H back to the way it was yesterday, since this is
+	compatible with FreeBSD and the POSIX spec is confusing
+	and somewhat contradictory.
+
+	* src/ls.c (DEREF_COMMAND_LINE_ARGUMENTS): Change name back
+	from DEREF_COMMAND_LINE_SYMLINK_TO_DIR, updating all uses.
+	(long_options): Change the long option name back.
+	(usage): Change the usage back.
+	(gobble_file): When -H is specified, dereference a top-level
+	arg even if it points to a non-directory.
+
+2003-01-15  Jim Meyering  <jim@meyering.net>
+
+	* src/ls.c (gobble_file): Fall back on using lstat when required:
+	when --dereference (-L) is not specified, and
+	- when operating on a dangling symlink
+	- when operating on command-line-symlink-to-directories
+	This fixes numerous problems.  Here are examples:
+	- `ls dangling-symlink' would fail with `no such file...'
+	Now it prints `dangling-symlink'.
+	- `ls -i symlink' would mistakenly print the inode of the referent.
+	Now it prints the inode of the symlink.  Likewise for --size (-s).
+	Based on a patch from Michael Stone.
+	Reported by Deepak Goel as Debian bug #173793.
+
+	Rename ls's --dereference-command-line (-H)
+	option to   --dereference-command-line-symlink-to-dir.
+	* src/ls.c [enum Dereference_symlink]
+	(DEREF_COMMAND_LINE_SYMLINK_TO_DIR): Rename from
+	DEREF_COMMAND_LINE_ARGUMENTS.  Update all uses.
+	(long_options): Rename the long option.
+	(usage): Say that --dereference-... changes how ls treats
+	only symlinks to directories specified on the command line.
+

+
+	* src/ls.c (gobble_file): Fix a bug introduced in 4.5.4 that made it
+	so that ls --color would no longer highlight the names of files with
+	the execute bit set when not specified on the command line.
+	Patch by Michael Stone.  Reported by Stephen Depooter as
+	Debian bug 175135.

+
+	* tests/shred/exact: Also test for just fixed bug with --zero.

+
+	* Makefile.maint (cvs-update): Skip any file with local modifications.

+
+	* Makefile.cfg ($(url_dir_list)): Use .../coreutils, not .../fetish.
+

+
+	* Version 4.5.4.

+	in case it's already defined.
+
+2002-12-09  Jim Meyering  <jim@meyering.net>

+	* tests/touch/fail-diag: Don't get a test failure if /no exists.
+	Instead, evoke a framework failure if /no-$$ exists.
+	Reported by Michael Stone.
+
+2002-12-08  Jim Meyering  <jim@meyering.net>
+
+	* src/du.c (lstat) [! LSTAT_FOLLOWS_SLASHED_SYMLINK]:
+	Define to rpl_lstat, so that even on systems like Solaris 5.8,
+	du honors (per POSIX) the trailing slash on an argument referring
+	to a symlink-to-directory.
+
+2002-12-06  Jim Meyering  <jim@meyering.net>
+

+
+2002-12-04  Jim Meyering  <jim@meyering.net>

+	no file on systems running some version of the DJGPP libc.
+
+2002-12-03  Jim Meyering  <jim@meyering.net>
+
+	* src/Makefile.am (AUTOMAKE_OPTIONS): Remove definition (to ansi2knr)
+	since this package no longer panders to K&R compilers.
+
+2002-12-02  Jim Meyering  <jim@meyering.net>
+
+	* tests/du/slink: Skip this test if `.' is on a non-local file system.

+
+2002-11-30  Jim Meyering  <jim@meyering.net>
+
+	* ls.c (gobble_file): Remove the block of code that caused
+	`ls --color -F symlink-to-dir' to list the files in
+	`symlink-to-dir/.'.  Now, it prints `symlink-to-dir@', (just
+	like `ls -F symlink-to-dir') but with the addition of highlighting.
+	Similarly, `ls --color -dF symlink-to-dir' would print
+	`symlink-to-dir/';  now it prints `symlink-to-dir@'.
+	Reported by Jeff Sheinberg as Debian bug #168203.
+	* tests/ls-2/tests (sl-F-color, sl-dF-color): New tests for the above.
+
+	ls is now more efficient: with certain options, it no longer needs
+	to stat each directory entry on systems with valid dirent.d_type.
+	* src/ls.c (print_dir): Add DT_LNK and DT_REG.
+	(main): Make --recursive set format_needs_type, not format_needs_stat.
+	(gobble_file): Remove a FIXME comment, now that it's fixed.
+
+2002-11-24  Jim Meyering  <jim@meyering.net>
+
+	* src/du.c (du_files): Don't strip any trailing slash.
+	Rewrite so that `/' is no longer represented internally as
+	the empty string.
+	(count_entry): When appending a file name component,
+	account for the fact that the current path may end in `/'.
+	François Pinard reported that `du symlink-to-dir/' was not
+	equivalent to `du symlink-to-dir/.'.  Now it is.
+	* tests/du/trailing-slash: New file/test, for the above fix.

+
+	* src/ls.c (decode_switches): Use case-sensitive matching to

+
+2002-11-19  Jim Meyering  <jim@meyering.net>

+	(release): Rename from `alpha'.
+	(alpha): Depend on release.
+
+	* Makefile.maint (signatures): Define with ?=, so it's easy to override.
+
+2002-11-14  Jim Meyering  <jim@meyering.net>
+
+	* Makefile.maint (mail_gpg_sign_cookie): Make optional.
+	(announcement): Use the new variable.
+
+	* Makefile.maint: Sync with Bison, i.e.:
+	(po-check): Scan .l and .y files instead of the
+	.c and the .h files that they generate.  This fixes the bug
+	reported by Tim Van Holder in:
+	<http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
+	Look for N_ as well as for _.  Try to avoid matching #define for
+	N_ and _.
+	From Paul Eggert.
+

+	(main): Use sigaction, if possible; otherwise signal.
+	Handle these signals:
+	SIGHUP, SIGINT, SIGPIPE, SIGQUIT, SIGTERM, SIGTSTP.
+	Don't register our handler if the signal is already being ignored.
+
+	* src/dd.c (interrupt_handler): Use raise, rather than kill+getpid.

+
+	* tests/misc/Makefile.am (TESTS): Add printf-hex.
+
+	* tests/misc/printf: Be careful to test the code in this package,
+	not the shell built-in function.
+
+	* src/printf.c (print_esc): A hexadecimal escape sequence has
+	at most two hex. digits, not three.  Reported by Padraig Brady.
+	(usage): Update description.
+	* tests/misc/printf-hex: New file/test, for the above fix.
+
+2002-10-07  Paul Eggert  <eggert@twinsun.com>
+
+	Add support for locale-specific size indications (e.g.,
+	thousands-separators) and for explicit size suffixes on output.
+
+	* doc/coreutils.texi (Block size): Say that:
+	This affects display format as well as block size.
+	Fractional block counts are rounded up.
+	ls file size blocksize defaults to 1.
+	A block size spec preceded by ' generates thousands separators.
+	A suffix without a preceding integer generates suffixes.
+	(tail invocation): 32k -> 32 KiB.
+	(What information is listed): ls -h is now equivalent to
+	ls --block-size=human, and ls -H is now equivalent to
+	ls --block-size=si.  Displayed file size is now always affected by
+	--block-size.
+
+	* lib/inttostr.c, lib/inttostr.h, lib/imaxtostr.c, lib/offtostr.c,

+	human_base_1024, human_SI, human_B): New enum values.
+	(human_readable): Rename from human_readable_inexact; put the
+	options before the sizes.  All uses changed.  The old human_readable
+	function has been removed; use inttostr.h instead.
+	(human_options): Renamed from human_block_size, with new signature
+	that allows block sizes up to UINTMAX_MAX.  All callers changed.
+
+	* m4/prereq.m4 (jm_PREREQ_HUMAN): Check for locale.h, localeconv,
+	AC_HEADER_STDBOOL.  No need to check for limits.h since it's in
+	freestanding C89.  No need to check for stdlib.h or string.h since
+	autoconf does this now.
+
+	* src/cksum.c (cksum): Use primitives from inttostr.h, not
+	human.h, to print large numbers simply.

+	block sizes.  All uses changed.
+	* src/du.c: Likewise.
+	* src/ls.c: Likewise.
+
+	* src/df.c (print_header): In the header line, prefer SI to human
+	representation if it's shorter; if neither is shorter, try to
+	intuit what the user would prefer.
+
+	* src/expr.c (inttostr): Remove; use new imaxtostr library
+	function instead.
+
+	* src/ls.c (file_output_block_size): New var, to distinguish
+	file sizes from other sizes.
+	(decode_switches): Set it.
+
+	* src/shred.c (OUTPUT_BLOCK_SIZE): remove.
+	(dopass): When printing progress, use floor for what has been done
+	so far (since we should be conservative there), and ceiling for
+	what needs to be done (since that's what other programs use).
+
+2002-10-19  Jim Meyering  <jim@meyering.net>

+
+	* src/system.h (ST_BLKSIZE): Correct comment describing how to
+	reproduce HPUX-11 cat failure.  From Petter Reinholdtsen.
+
+2002-10-17  Jim Meyering  <jim@meyering.net>
+
+	Fix a problem that could make e.g., `cat' misbehave on systems which
+	give invalid (unreasonably large) values for stat.st_blksize.
+	* src/system.h (ST_BLKSIZE): Ensure that the result is in [1..4MB].
+	Reported by Petter Reinholdtsen.
+
+2002-10-14  Jim Meyering  <jim@meyering.net>
+
+	Specifying a printf conversion specifer as nl's separator string
+	could cause nl to segfault.
+	* src/nl.c (build_print_fmt): Don't include separator string
+	in the printf format; it might contain `%'.
+	Use a better bound on the length of the print_fmt buffer.
+	(print_lineno): Print the separator here instead.

+2002-10-12  Jim Meyering  <jim@meyering.net>
+
+	* src/paste.c (paste_parallel): Declare local, `delims_saved', to be
+	of type size_t, since that's the way it's used and avoids a warning.
+
+	* src/csplit.c (struct cstring) [len]: Declare to be unsigned int,
+	since that's how it's always used and avoids a new warning from gcc.
+	(read_input): Adapt to new safe_read ABI.
+
+	* src/cut.c (cut_fields): Add a temporary size_t variable, n_bytes,
+	to avoid warnings.
+
+	* src/pinky.c (print_long_entry): fread returns size_t.
+	Declare local `bytes' accordingly, to avoid warning.
+
+	tail -c +N would perform an extra read after encountering EOF
+	[this change is analogous (bytes vs. lines) to the one of 2002-01-27]
+	* src/tail.c (start_bytes): Detect EOF, inform caller.
+	(tail_bytes): Upon EOF in start_bytes, return immediately.

+
+	* tests/cp/backup-is-src: Ensure that certain environment variables
+	are not set (e.g., SIMPLE_BACKUP_SUFFIX).  Reported by Duncan Roe.
+
+	* tests/tail-2/big-4gb: Mark this as an expensive test; it would
+	consume 4GB of disk space on systems without support for sparse files.
+	Fix a logic error that'd make it `cat err' even though dd didn't fail.

+	* tests/du/slink: New test for system.h change of 2002-08-31.
+
+	In move mode, always first try to rename.  Before, upon failure to

+	other file in that directory, but would thenceforth always copy.
+	On some systems (e.g., NetApp's OnTap-6.4), renaming a directory
+	may fail with EXDEV, yet renaming files within that directory to
+	a newly-created destination directory succeeds.
+	* src/copy.c (copy_internal): Remove local, move_mode;
+	use x->move_mode instead.  Based on a patch from Tom Haynes.
+
+2002-09-28  Jim Meyering  <jim@meyering.net>

+	(fillbuf, keycompare): Cast literal `-1' to size_t in comparisons,
+	to avoid compiler warnings.
+
+	* src/shred.c (dopass): Use a uintmax_t temporary to avoid bogus
+	compiler warnings.
+
+	Fix things so `mkdir -p' can create very deep directories, e.g.,
+	mkdir -p $(perl -e 'print "a/" x 40000') now works.
+	* src/mkdir.c (main): For --parents (-p), call make_path with the
+	entire directory name, so we don't ever require that file operations
+	like stat or chmod be performed on the entire command line argument.
+	* makepath.c (make_path): Restore umask *before* creating the final
+	component.
+
+2002-09-27  Andreas Schwab  <schwab@suse.de>
+
+	* src/tail.c (tail_bytes): Change type of bytes_remaining to off_t

+
+2002-09-26  Jim Meyering  <jim@meyering.net>
+
+	* src/install.c (get_ids): Use strtoul, not strtol.  Remove some casts.

+
+	* src/rmdir.c: Include "dirname.h", for declaration of
+	strip_trailing_slashes.

+
+	* src/cp-hash.c, src/dd.c, src/df.c, src/du.c, src/ls.c,
+	* src/stat.c, src/wc.c: Remove all inclusions of inttypes.h,
+	since it's already included from sys2.h via system.h.
+
+	* Use automake-1.6f.  Regenerate dependent files.
+
+	* src/Makefile.am (PERL): Remove duplicate definition.
+
+	fmt's -s, -t, -c options didn't work properly for long lines.
+	Since get_line may end up calling put_paragraph (for long lines),
+	be sure to set global, `other_indent', before it is used there.
+
+	* src/fmt.c (set_other_indent): New function, factored out of...
+	(get_paragraph): ... here.  Call it.
+	(get_line): Call set_other_indent before calling flush_paragraph,
+	which calls fmt_paragraph, which in turn calls put_paragraph,
+	which uses other_indent.
+
+	* tests/fmt/Makefile.am (TESTS): Add long-line.
+	* tests/fmt/long-line: New file/test, for the above fix.
+
+2002-09-21  Jim Meyering  <jim@meyering.net>

+	* src/install.c: Likewise.
+	Suggestion from Bruno Haible.
+
+2002-09-06  Andreas Schwab  <schwab@suse.de>
+
+	`rmdir -p dir-specified-with-trailing-slash/' would fail.
+	* src/rmdir.c (remove_parents): Strip trailing slashes.

+
+2002-09-18  Jim Meyering  <jim@meyering.net>
+
+	`od -t x8' used the wrong (`l'-prefixed) printf format.
+	Likewise for the o8 and u8 formats.
+	* src/od.c (ISPEC_TO_FORMAT): Define macro.
+	(decode_one_format): Use PRIdMAX, PRIoMAX, etc. for LONG_LONG.
+	Reported by Arun Sharma.
+
+2002-09-17  Jim Meyering  <jim@meyering.net>

+	warning about `signed and unsigned type in conditional expression'.
+
+2002-09-14  Jim Meyering  <jim@meyering.net>
+
+	* src/who.c (print_user): Change type of local to size_t
+	to avoid warnings about `comparison between signed and unsigned'.
+	* src/ptx.c (generate_all_output): Likewise.
+
+	* src/dd.c (main, skip): Add casts to avoid warnings about
+	`comparison between signed and unsigned'.
+
+	* src/id.c (print_full_info, print_group_list): Add casts to avoid
+	warnings about `signed and unsigned type in conditional expression'.
+
+	* src/md5sum.c: Change type of global, digest_hex_bytes, to size_t
+	to avoid warnings about `comparison between signed and unsigned'.
+	(split_3): Change parameter names to be readable and add comment.
+	Clean up the test for whether a line may be ignored.
+
+2002-09-13  Jim Meyering  <jim@meyering.net>
+
+	* src/printf.c (main): Handle leading command line argument of `--'.
+	Reported by Raul: DervishD <raul@pleyades.net>

+	* tests/misc/Makefile.am (TESTS): Add printf.
+
+	* src/date.c (usage): Explain that %S's range of [0..60] is required --
+	rather than 0..59 -- to accommodate the occasional positive leap second.
+	Reported by Richard Neill.
+
+2002-09-12  Jim Meyering  <jim@meyering.net>
+
+	* src/Makefile.am (nanosec_libs): Define.
+	(sleep_LDADD, tail_LDADD): Use it here.
+
+	Factor nanosleep-related code into ../lib/xnanosleep.c.
+	* src/sleep.c: Include xnanosleep.h.
+	Factor out fenv.h-related code.
+	(timespec_subtract): Remove function.
+	(main): Remove code that deals with computing start and stop times
+	as well as the loop around nanosleep.  Now that's in xnanosleep.c.
+
+	Allow S (in --sleep-interval=S) to be a floating point value.
+	* src/tail.c: Include xnanosleep.h and xstrtod.h.
+	Move declaration of global variable, sleep_interval, to ...
+	(main): ...here.
+	(usage): Update description of --sleep-interval option.

+
+2002-09-06  Jim Meyering  <jim@meyering.net>
+

+
+	* src/kill.c (print_table_row): Use an unsigned type for widths
+	to avoid warning about comparison between signed and unsigned.
+	(list_signals): Likewise.
+
+	* src/od.c (skip): Add a cast to avoid warning about comparison
+	between signed and unsigned.
+	* src/install.c (get_ids): Likewise.  Also rearrange range-checking
+	comparisons to make them more readable.
+
+2002-09-01  Jim Meyering  <jim@meyering.net>
+
+	* Version 4.5.1.
+
+2002-08-31  Jim Meyering  <jim@meyering.net>
+
+	Symlinks were always reported as using 0 blocks.
+	* src/system.h (ST_NBLOCKS): Don't depend on file type.
+	This reverts the change of 2000-01-30.
+	Based on a report and patch from Neil Brown via Michael Stone.
+	This fixes Debian Bug#156358.
+
+	* Most files: Change `exit (0)' to `exit (EXIT_SUCCESS)',
+	`exit (1)' to `exit (EXIT_FAILURE)', and
+	`usage (1)' to `usage (EXIT_FAILURE)'.
+
+	* chgrp.c, chmod.c, chown.c, chroot.c, cp.c, date.c, dd.c, du.c,
+	* hostname.c, id.c, install.c, ln.c, mkdir.c, mkfifo.c, mknod.c,

+	* users.c, who.c: Change `error (1, ...' to `error (EXIT_FAILURE, ...'.
+	But don't change `error (0, ...' to `error (EXIT_SUCCESS, ...', since
+	error never exits successfully.
+
+2002-08-29  Jim Meyering  <jim@meyering.net>
+
+	* src/remove.c (remove_cwd_entries): Use closedir (not CLOSEDIR)
+	when ignoring any return value.
+
+	* src/remove.c (remove_cwd_entries): Detect and diagnose readdir
+	failures.  On some systems (at least EMC Celerra and Solaris5.8),
+	this appears to be necessary.
+	(is_empty_dir): Likewise.  Also, always close directory handle.
+	* src/ls.c (print_dir): Likewise.
+	(print_dir): Rename local variable: reading -> dirp.
+	Reported by Mike Coleman.
+
+2002-08-28  Jim Meyering  <jim@meyering.net>
+
+	* src/remove.c (remove_cwd_entries): Use CLOSEDIR, not closedir.

+
+	* src/cat.c (close_stdout_wrapper): New, kludgey, function and
+	file-scoped global.
+	(main): Register it with atexit.

+	/dev/audio on at least Solaris 5.7 and 5.8 systems.
+	Reported by Shing-Shong Shei.
+
+2002-08-25  Jim Meyering  <jim@meyering.net>

+
+2002-08-10  Paul Eggert  <eggert@twinsun.com>
+
+	* src/nohup.sh: Don't use "exec --"; it's not portable and
+	shouldn't be needed.
+
+2002-08-09  Jim Meyering  <jim@meyering.net>
+
+	* src/pr.c (main): Don't ignore -COLUMN if it's the last option.
+	(usage): Clarify help text for the -COLUMN option.
+	Patch by Padraig Brady.
+	* tests/pr/Test.pm [col-last]: New test for the above.
+
+	* configure.ac: Start with version 4.5.1, chosen so that it's larger
+	than the latest version numbers of the component packages.
+
+	* man/Makefile.am (check-x-vs-1): Set and export PATH so we use
+	programs in ../src.
+
+2002-08-08  Jim Meyering  <jim@meyering.net>
+
+	* src/date.c: Guard inclusion of <langinfo.h> with
+	`#if HAVE_LANGINFO_CODESET', not `#if HAVE_LANGINFO_H'.
+	* src/sort.c: Likewise.
+	Patch by GOTO Masanori.
+
+2002-08-05  Paul Eggert  <eggert@twinsun.com>
+
+	Fix some minor time-related bugs with POSIX time arguments.
+	Some valid time stamps were being rejected (notably -1, and
+	time stamps before 1900 on 64-bit hosts).  And some invalid
+	time stamps were being accepted, e.g. September 31.
+
+	* src/date.c (main): Adjust to posixtime signature change.
+	* src/touch.c (main): Likewise.  Remove unnecessary initialization.
+	Use localtime, not posixtm, to warn about obsolete "touch".

+
+2002-08-02  Paul Eggert  <eggert@twinsun.com>

+
+	* src/uniq.c: Include hard-locale.h, xmemcoll.h.
+	(hard_LC_COLLATE): New var.
+	(different): Args are now char *, not const char *.
+	Use xmemcoll instead of memcmp to compare lines, so that
+	LC_COLLATE has effect.  However, use memcmp if it is an
+	easy locale.
+	(check_file): Do not include newline in comparison, so that
+	xmemcoll has a byte to stomp on temporarily.
+	(main): Set hard_LC_COLLATE.
+
+2002-07-29  Jim Meyering  <jim@meyering.net>
+

+
+	* src/Makefile.am (uninstall-local): Search for @GNU_PACKAGE@,

+	textutils, and sh-utils.
+	* Makefile.am: Likewise.
