2004-08-09  Paul Eggert  <eggert@cs.ucla.edu>

	* Makefile.am (libfetish_a_SOURCES): Add getpass.h.
	* getpass.h: New file.
	* .cpp-disable: Add it.
	* getpass.c [!_LIBC]: Include it.

	* obstack.h (obstack_empty_p):
	Don't assume that chunk->contents is suitably aligned.
	* obstack.c (_obstack_begin, _obstack_begin_1, _obstack_newchunk):
	Likewise. Problem reported by Benno in
	<http://sources.redhat.com/ml/libc-alpha/2004-08/msg00055.html>.

	* chown.c (rpl_chown): Work even if the file is writeable but not
	readable.  This could be improved further but it'd take some work.
	* fts.c (diropen): New function.
	(fts_open, fts_read, fts_children, fts_safe_changedir):
	Use it, so that the code works even if the directory
	is writeable but not readable.  We'd like it to work even if
	the directory is merely executable, but I don't know how to do
	that portably.

	* xalloc-die.c: New file.
	* xalloc.h (xalloc_fail_func, xalloc_msg_memory_exhausted): Remove.
	All uses removed.
	* xmalloc.c (xalloc_fail_func, xalloc_msg_memory_exhausted): Likewise.
	Move inclusions of gettext.h, error.h, exitfail.h to xalloc-die.c.
	(_, N_, xalloc_die): Move to xalloc-die.c.
	* userspec.c (parse_user_spaec): Use xstrdup rather than strdup,
	so that we needn't mess with xalloc_msg_memory_exhausted.

	* sha1.h (sha1_ctx): Renamed from sha_ctx.
	(sha1_init_ctx): Renamed from sha_init_ctx.
	(sha1_process_block): Renamed from sha_process_block.

	* sha1.c: Likewise.

2004-08-07  Paul Eggert  <eggert@cs.ucla.edu>

	* .cppi-disable: Change fnmatch.h to fnmatch_.h.
	* .cvs-ignore: Add fnmatch.h, poll.h, stdbool.h, sysexit.h.

	* gettime.c (gettime): Fall back on `time' if `gettimeofday'
	doesn't work.
	* settime.c: Include <unistd.h>, for stime (on Solaris 8, anyway).
	(ENOSYS): Define if not defined.
	(settime): Fall back on stime if it exists and settimeofday fails.
	But don't bother with fallbacks if a method fails with errno == EPERM.

	* obstack.h: Add white space.

	* printf-parse.c, printf-parse.h, vasnprintf.c: Merge changes from
	gnulib, but rewrite to avoid "xsize.h".

2004-08-04  Paul Eggert  <eggert@cs.ucla.edu>

	* mountlist.c (SIZE_MAX): Define after including files, to avoid
	a collision on OpenBSD 3.4.

	* fts.c (LONGEST_MODIFIER): New macro.
	(PRIuMAX) [!PRI_MACROS_BROKEN && !defined PRIuMAX]: New macro.
	(find_matching_ancestor): Use it for dev_t and ino_t.

	* getndelim2.c: Sync from gnulib.

	* error.c: Work around bug in OpenBSD 3.4 sterror_r: it
	sometimes returns a positive errno value even when it succeeds.

	* nanosleep.c: Include stdbool.h.  Use bool for booleans.

	* xgethostname.c: Don't include <sys/types.h> or "exit.h";
	no longer needed.
	(errno): Remove decl; we now assume C89 or better.
	Include unistd.h if available, for gethostname.
	(ENAMETOOLONG): Define to 0, not 9999, to avoid colliding with
	existing errno values if any.
	(gethostname): Remove decl, since unistd.h declares it (or doesn't,
	in which case it's an older system and it should just work).
	(xgethostname): Don't assume host name length is less than INT_MAX.
	Exit if malloc fails, just as the comment says.

	(errno): Remove decl; we now assume C89 or better.
	(save_cwd): Use bool for booleans.
	(save_cwd, restore_cwd): Return -1 on failure, not 1, since we set
	errno on failure.

	* readutmp.h (UT_USER): Parenthesize properly.
	(UT_USER_SIZE): New constant.
	(read_utmp): Don't assume that the number of users is less than
	INT_MAX.
	* readutmp.c (read_utmp): Likewise.
	Check for integer overflow in size calculations.
	Return -1 (not 1) on failure, since we set errno in that case.

	* posixtm.c (posix_time_parse): Don't assume that the length of
	the string being parsed is <= UINT_MAX.

	* mountlist.h (read_file_system_list): Accept bool flag, not int.
	* mountlist.c (read_file_system_list): Likewise.
	* mountlist.h: Include <stdbool.h>.
	* mountlist.c (errno): Remove decl; we now assume C89 or better.
	(xatoi): Remove; replaced by strtoul.  Hence device numbers can now
	go up to ULONG_MAX.

	* isdir.c: Remove; no longer needed.
	* Makefile.am (libfetish_a_SOURCES): Remove isdir.c.

	* fts_.h: Add an FSF copyright notice, since our changes are becoming

	than INT_MAX entries in a directory.
	(FTS_ROOTPARENTLEVEL): Parenthesize properly.
	(FTSENT.fts_level): Now ptrdiff_t, not int, to allow recursing more
	than INT_MAX levels deep on 64-bit hosts.
	(FTSENT.fts_namelen): Now size_t, not u_short, to support hosts like
	the Hurd that don't have arbitrary limits on directory entry lengths.
	(FTSENT.fts_statp): Now an array, not a pointer, so that we don't
	have to play unportable games with pointer arithmetic.  Keep it array
	for the benefit of user code that assumes it is a pointer.
	* fts.c: Include stdint.h if available, as Autoconf suggests.
	(ALIGNBYTES, ALIGN): Remove; no longer needed now that fts_statp
	is an array.
	(fts_alloc, fts_palloc, fts_sort, fts_load, fts_build):
	Use size_t for sizes.
	(fts_stat, fts_safe_changedir, fts_debug, fts_read, fts_build,
	fts_palloc):
	Use bool when appropriate.
	(SIZE_MAX, TYPE_SIGNED): New macros.
	(fts_read): Use u_short for instructions.
	(fts_build): Use ptrdiff_t for levels.  Don't assume file name lengths
	fit into int.  Don't assume nlink_t is signed.
	(find_matching_ancestor): Don't assume dev, ino fit in int.
	(fts_stat): Use function prototype; required for bool arg.
	(fts_sort): Detect integer overflow in size calculations.

	(struct fs_usage): Use uintmax_t for block sizes, so that they're
	not limited to INT_MAX.

	Include <stdbool.h>.
	* dirname.c (dir_name): Use bool when appropriate.

	* argmatch.h (argmatch, __xargmatch_internal, argmatch_invalid):
	Use ptrdiff_t, not int, when counting arguments, to allow more
	than INT_MAX arguments.

2004-08-01  Paul Eggert  <eggert@cs.ucla.edu>

	* safe-read.c (errno): Remove decl; we now assume C89 or better.
	(safe_rw): Don't work around Tru64 bug unless the bug symptoms
	manifest themselves.  This allows us to do proper reads and writes
	on other hosts, e.g., "dd" with a block size greater than 2**31.

	* md5.c (UNALIGNED_P): Use size_t; in practice, this is just as
	good as uintptr_t in checking for alignments, and has fewer
	configuration hassles.
	* sha1.c (UNALIGNED_P): Likewise.
	* md5.h: Don't include <limits.h>.  Include <inttypes.h> if available,
	as it defines symbols like UINT32_MAX on Solaris 8.
	(md5_uint32): Assume uint32_t exists; Autoconf will define it
	otherwise (if the host has a 32-bit unsigned type, anyway).
	* memchr.c: Don't include inttypes.h or stdint.h.
	(UNALIGNED_P): Remove.
	(__memchr): Use size_t, not uintptr_t, to test alignment.
	* memrchr.c: Likewise, for __memrchr.

2004-07-30  Paul Eggert  <eggert@cs.ucla.edu>

	* makepath.h: Include <stdbool.h>.
	(make_path, make_dir): Use bool, not int, since we're not setting
	errno.
	Use mode_t for modes, not int.  All uses changed.
	* makepath.c: Likewise.
	(errno): Remove decl; no longer needed since we assume C89.

2004-07-29  Paul Eggert  <eggert@cs.ucla.edu>

	* modechange.c: Include <stdbool.h>.
	(mode_compile): Use bool when appropriate.

	* memchr.c (UNALIGNED_P): Use sizeof, not alignof, for better
	performance on m68k-linux.  Reported by Andreas Schwab in
	<http://lists.gnu.org/archive/html/bug-coreutils/2004-07/msg00104.html>.
	* memrchr.c (UNALIGNED_P): Likewise.

2004-07-28  Paul Eggert  <eggert@cs.ucla.edu>

	* userspec.c: Include <stdbool.h>, "inttostr.h".
	(V_STRDUP): Don't assume the string's length fits in int.
	(ISDIGIT): unsigned -> unsigned int
	(is_number): Define only ifdef __DJGPP__; not needed elsewhere.
	Use bool instead of int where appropriate.
	Do not allow empty strings.
	(parse_user_spec): Parse numbers as decimal integers, even if
	they have a leading 0.  Don't assume uids and gids fit in int.

	* memchr.c: Include <stddef.h>, not <stdlib.h> and <sys/types.h>.
	(LONG_MAX_32_BITS): Remove.
	Include <inttypes.h> and <stdint.h> if available.
	(alignof, UNALIGNEDP): New macro, portable to all C89 hosts.
	(__memchr): Don't assume unsigned long int is either 4 or 8 bytes;
	let it be any number of bytes greater than or equal to 4.
	* memrchr.c: Likewise, with __memrchr.

	* md5.h: Include <stdint.h> if HAVE_STDINT_H || _LIBC, not
	ifdef _LIBC.
	(md5_uint32): Use uint32_t if available.  Simplify fallback ifdefs.
	* md5.c: Don't include <sys/types.h> or <stdlib.h>; <stddef.h>
	suffices with C89 or better.
	(alignof): New macro, portable to all C89 hosts.
	(UNALIGNED): Use it.  Use uintptr_t if available, and assume
	everything is unaligned otherwise; this is more portable than
	assuming 'unsigned long int' will always work.
	* sha1.c: Likewise.

	* getugroups.c: Include <errno.h>.
	(EOVERFLOW): Define if not defined.
	(getgroups): Return -1 with errno=EOVERFLOW if an integer overflow
	occurs.

2004-07-27  Paul Eggert  <eggert@cs.ucla.edu>

	* euidaccess.c [HAVE_LIBGEN_H]: Include <libgen.h>, for
	eaccess on Solaris and SVR4-like systems.
	(euidaccess): Use HAVE_EACCESS, not HAVE_DECL_EACCESS.

	cycle-check integer overflow fixup.

	* cycle-check.h: Remove now-inaccurate comment about the files
	you need to include first.  You don't need to include any files
	other than the usual config.h.
	Include <inttypes.h> and <stdint.h> if available, for uintmax_t.
	Remove 'struct stat;' not needed since we know sys/stat.h has
	been included by dev-ino.h.
	(struct cycle_check_state): Change chdir_counter to uintmax_t,
	not size_t, since it isn't limited by object sizes.
	Change magic from long unsigned int to int; that's good enough
	for our use.
	* cycle-check.c (is_zero_or_power_of_two): Renamed from
	is_power_of_two, to reflect better what it really does.
	All uses changed.  Arg is now uintmax_t, not unsigned int
	(it should have been unsigned long int -- that was a bug).
	(cycle_check): Check for integer overflow in cycle count,
	and report a cycle if that happens, as it must be a cycle
	by this point.

	backupfile.c rewrite to avoid arbitrary limits on lengths of
	numeric backup extensions.

	* addext.c: Remove; no longer needed.
	* Makefile.am (libfetish_a_SOURCES): Remove addext.c.
	* backupfile.h (addext): Remove decl.
	* backupfile.c: Include "backupfile.h" first.
	Include errno.h, stdbool.h, limits.h, unistd.h, xalloc.h.
	(CLOSEDIR, INT_STRLEN_BOUND): Remove.
	(pathconf) [! (HAVE_PATHCONF && defined _PC_NAME_MAX)]: New macro.
	(_POSIX_NAME_MAX) [!defined _POSIX_NAME_MAX]: New macro.
	(NAME_MAX_MAXIMUM): New macro.  Unlike the old addext.c, we
	also look at _XOPEN_NAME_MAX, for better performance on modern
	hosts that support only file names of length 255 or more.
	(ISDIGIT): unsigned -> unsigned int
	(max_backup_version, version_number): Remove.
	(check_extension): New function.  Similar to the old addext, but
	static, assumes that the extension has already been added,
	and a bit more careful on DOS hosts.
	(numbered_backup): New function.  It does what max_backup_version
	and version_number used to do, but it doesn't use integer arithmetic
	to calculate extensions so it doesn't overflow.
	(find_backup_file_name): Rewrite to use these new functions.
	This has a new optimization: we needn't call pathconf if the
	new numbered backup name has the same length as the old.
	Also, use xmalloc rather than malloc, so that the caller
	needn't worry about memory exhaustion.

2004-07-25  Paul Eggert  <eggert@cs.ucla.edu>

	* euidaccess.c [!defined LIBC]: Included group-member.h, stat-macros.h.
	(S_IXUSR, S_IXGRP, S_IXOTH, S_IROTH, S_IWOTH, S_IXOTH):
	Remove; now done by stat-macros.h.
	(NGROUPS_MAX, group_member): Remove; now done by group-member.h.
	No need to include <limits.h>.
	(errno): Remove decl; we now assume C89 or better.
	(access, getuid, getgid, geteuid, getegid, stat) [defined _LIBC]:
	New macros.
	(uid, gid, have_ids): Remove these static variables.
	They weren't accurate for programs that also invoked setreuid etc.
	(euidaccess) [defined EFF_ONLY_OK || defined ACC_SELF ||
	HAVE_DECL_EACCSS]: Use builtin substitutes.
	[defined _LIBC]: Ignore __libc_enable_secure; it's not a
	correct optimization for programs run as root that later
	invoke setreuid.
	[no builtin substitutes && HAVE_DECL_SETREGID &&
	PREFER_NONREENTRANT_EUIDACCESS]:
	Use setreuid+setregid to get the correct answer.
	[no builtin substitutes && ! (HAVE_DECL_SETREGID &&
	PREFER_NONREENTRANT_EUIDACCESS)]:
	Don't assume that the stat macros have their historical values,
	as POSIX doesn't require this.
	[defined TEST]: Include <stdlib.h>; don't include errno.h
	twice; include <error.h> rather than "error.h".

2004-07-23  Paul Eggert  <eggert@cs.ucla.edu>

	* Makefile.am (libfetish_a_SOURCES): Add fcntl-safer.h,
	open-safer.c.
	* fcntl-safer.h, open-safer.c: New files.

	* c-strtod.c (STRTOD_L): New macro.
	(C_STRTOD) [defined LC_ALL_MASK]: Use it, so that the
	code is reentrant on platforms that have strtod_l.

	* getloadavg.c: Include <errno.h>, <stdio.h>, <stdlib.h> even
	if HAVE_GETLOADAVG is defined, so that the test program can work.
	(errno): Remove declaration; not needed in C89 or later.
	Include "c-strtod.h".
	Do not include locale.h or define setlocale; no longer needed.
	Include <limits.h>.
	(INT_STRLEN_BOUND): New macro.
	(getloadavg): Use it to compute buffer size.
	Don't assume that buffer will be properly terminated by 'read'.
	Use c_strtod instead of setlocale.
	(main) [defined TEST]: Return int, not void.

2004-07-11  Paul Eggert  <eggert@cs.ucla.edu>

	* Makefile.am (libfetish_a_SOURCES): Add c-strtold.c.
	* c-strtold.c: New file.
	* c-strtod.c: Include <config.h> first.
	(C_STRTOD, DOUBLE, STRTOD): New macros.
	(c_strtod): Use them.
	* c-strtod.h (c_strtold): New decl.

2004-07-07  Jim Meyering  <jim@meyering.net>

	Don't infloop when MAXSYMLINKS is not defined.
	Detect symlink loops much earlier (albeit lazily) on systems
	with MAXSYMLINKS defined to a large value.

	* canonicalize.c: Include "cycle-check.h".
	(canonicalize_filename_mode): Don't try to detect loops by counting
	symlink-hops.  Instead, use the cycle-check module.

	* cycle-check.h: Include stdbool.h.
	Forward-declare `struct stat'.

	* canonicalize.c (canonicalize_filename_mode): Remove do-while(0) loop.
	Replace each corresponding `break' stmt with `continue'.

2004-07-06  Jim Meyering  <jim@meyering.net>

	* canonicalize.c: Include "stat-macros.h".
	(canonicalize_filename_mode): Remove #ifdef S_ISLNK, now that

	never returns NULL.
	* path-concat.c (mempcpy): Don't define if a system header defines it.
	Don't include stdio.h, stdlib.h, unistd.h, strdup.h.

	stat, even if the user isn't interested in the results.
	This prevents a core dump in cycle_check when FTS_NOSTAT is set.

	is what POSIX-2004 specifies.
	* lchown.h (EOPNOTSUPP): Define if not defined.

	* nanosleep.c (suspended): Change its type from int to
	sig_atomic_t volatile.
	(first_call): Make it private to rpl_nanosleep, and have it
	be zero initially as that's a bit faster.

2004-03-15  Jim Meyering  <jim@meyering.net>

	`date --date="21:04 +0100" +%S' would print the seconds value
	from the current time, rather than `00'.

	Now a macro referring to exit_failure, instead of a separate
	variable.  Include "exitfail.h" to get it.
	* xstrtol.h: Include "exitfail.h".

	* stdbool.hin: Remove file.

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

2003-07-23  Jim Meyering  <jim@meyering.net>

	* xstrndup.h: New file.
	* xstrndup.c: New file, factored out of dircolors.c from coreutils.

	* closeout.h (close_stdout_set_status, close_stdout_status): Remove.
	* closeout.c: Likewise.  Include "closeout.h" right after config.h,
	to test that it can stand by itself.  Include "exitfail.h".
	Clients should set exit_failure instead.
	(EXIT_FAILURE): Remove; no longer needed.  Do not include <stdlib.h>.

2003-07-18  Andreas Schwab  <schwab@suse.de>

	* memcoll.c (memcoll) [!HAVE_STRCOLL]: Clear errno.

	* Makefile.am (BUILT_SOURCES): Use `BUILT_SOURCES += $(STDBOOL_H)'
	rather than `all-local: $(STDBOOL_H)'.  The latter didn't force

	FIXME: but still need to adjust m4/mktime.c so that this fixed
	version is used when needed.

	Fix the bug that would make `du /' omit the `/' on the last line.
	E.g., `du --exclude '[^/]*' -x /' would print only "4\t\n" for me.
	* ftw.c (ftw_dir): Don't clobber the leading `/'.
	Reported by Chris Lesniewski as http://bugs.debian.org/200542.

2003-07-04  Jim Meyering  <jim@meyering.net>

	* quote.c: Don't include <stddef.h> or <sys/types.h>; not needed.
	* modechange.c: Include <stddef.h>.
	(NULL): Don't define, since <stddef.h> does that.
	* memcoll.h: Include <stddef.h>, to get size_t.
	* memcoll.c: Include "memcoll.h", which gets us size_t and checks

	(HAVE_LIMITS_H): Remove.  Assume it's 1.
	(__P): Remove; not used.
	(CHAR_BIT, INT_MIN, INT_MAX): Remove; <limits.h> defines them.

	main): Use prototypes.  Use const * where appropriate.
	(main): Fix typo in testing code that uncovered by above changes.

2003-05-07  Paul Eggert  <eggert@twinsun.com>

	* xnanosleep.c (timespec_subtract): Don't modify the 2nd arg.
	Work even if X-Y overflows when subtracting.  Make explicit the
	assumption that tv_nsec must be in range.
	(clock_get_realtime): Remove.  All callers changed to invoke gettime,
	for simplicity.
	(xnanosleep): Check for gettime failure every time.

2003-05-06  Jim Meyering  <jim@meyering.net>

	* xnanosleep.c (clock_get_realtime): Use gettime.c's gettime function,
	rather than an inferior, open-coded version that would fail on
	AIX systems due to clock_gettime failing with errno == ENOSYS.
	Reported by Jérôme Zago.

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

	Avoid array overrun.
	* ftw.c (nftw_arr): Update to reflect complete list of members.

2003-05-04  Jim Meyering  <jim@meyering.net>

	* setenv.c (__set_errno, LOCK, UNLOCK): Define.
	(unsetenv): Update from GNU libc.
	Ifdef-out this function, since the only caller
	is putenv.c and that file now has its own copy.

	This avoids a core dump on systems without GNU putenv,
	when running `env -u SOME_ALREADY_UNSET_VARIABLE'.
	* putenv.c (__set_errno, LOCK, UNLOCK): Define.
	(unsetenv): New static function, from GNU libc.
	(rpl_putenv): Use it.

2003-05-02  Jim Meyering  <jim@meyering.net>

	* canonicalize.c (canonicalize_file_name) [!HAVE_RESOLVEPATH]:
	A memory-allocation error could result in heap corruption.  Fix it

2003-04-10  Jim Meyering  <jim@meyering.net>

	* canonicalize.c (canonicalize_file_name) [HAVE_RESOLVEPATH]: Remove
	stray semicolon that caused `readlink --canonical RELATIVE_NAME' to
	fail on e.g., Solaris systems.  Reported by Bruce Korb.
	(canonicalize_file_name): Return NULL immediately if resolvepath fails.
	Otherwise, `readlink --canonical /no-such-file' would exhaust
	virtual memory on some systems (e.g. Solaris).
	(canonicalize_file_name): Always free `extra_buf' before returning.
	(canonicalize_file_name): NUL-terminate the result.

2003-04-05  Jim Meyering  <jim@meyering.net>

	* Makefile.am (DEFS): Use += notation rather than `DEFS = ... @DEFS@'.
	Use $(VAR) rather than @VAR@, now that we can rely on automake to
	emit a definition for each substituted variable.

2003-03-26  Richard Dawe  <rich@phekda.freeserve.co.uk>

	* dirname.c [TEST_DIRNAME]: Update build instructions for test.

2003-03-22  Jim Meyering  <jim@meyering.net>

	* strftime.c (widen): Cast alloca return value to proper type.

	* fnmatch_loop.c
	(NEW_PATTERN): Cast alloca return value to proper type.
	Otherwise, it wouldn't compile with at least /bin/cc on
	ymp-cray-unicos9.0.2.X.
	Combine two mostly-identical uses of alloca into one.
	Thanks to the Cray-Cyber project for access to a Cray Y-MP.

2003-03-19  Jim Meyering  <jim@meyering.net>

	DJGPP doesn't have S_ISLNK, so provide a replacement.
	* ftw.c (S_IFMT): Define, if necessary.

2003-03-18  Jim Meyering  <jim@meyering.net>

	* mountlist.c (read_filesystem_list) [MOUNTED_VMOUNT]: Detect any
	error from mntctl.
	Use mntctl's return value to drive the entry-processing loop, since
	we can't rely on the value of the vmt_length member in the last
	entry.  On some systems doing so could result in exhausting
	virtual memory.  Based in part on a patch from Mike Jetzer.

	* quote.c (quote_n): Fix typo in comment.

2003-03-17  Jim Meyering  <jim@meyering.net>

	* raise.c (raise): Rename from rpl_raise.
	Without that change, systems lacking raise (SunOS 4) would not be
	able to link programs using raise.  Reported by Volker Borchert.

	* ftw.c (FTW_STAT): Rename from `STAT', to avoid conflict
	with STAT definition from <sys/dir.h> on AIX 5.1.
	Suggestion from Mike Jetzer and Petter Reinholdtsen.

	* fchown-stub.c (fchown): Put function type on its own line.
	* readlink-stub.c (readlink): Likewise.

2003-03-14  Jim Meyering  <jim@meyering.net>

	* Makefile.am (AUTOMAKE_OPTIONS): Remove definition --
	before it pointed to ../src/ansi2knr.  Some of these files

	(libfetish_a_SOURCES): Remove unused files: c-stack.c, c-stack.h.

2003-02-04  Dmitry V. Levin  <ldv@altlinux.org>

	* stat.c: Include "xalloc.h".

2003-03-13  Paul Eggert  <eggert@twinsun.com>

	Merge changes from Bison.
	* obstack.h: (__INT_TO_PTR) [__STDC__]: Cast result to
	(void *) to avoid diagnostic with native c89 on SGI IRIX 6.5
	when compiling Bison 1.875's `bitset bset = obstack_alloc
	(bobstack, bytes);'.  Problem reported by Nelson H. F. Beebe.

2003-01-30  Richard Dawe  <rich@phekda.freeserve.co.uk>

	* fchown-stub.c: New file: trivial stub for fchown.
	* lstat-stub.c: New file: trivial stub for lstat.

2003-03-09  Jim Meyering  <jim@meyering.net>

	* ftw.c: Include "save-cwd.h".
	(ftw_startup): Avoid use of getcwd, if possible.
	Instead, use fopen/fchdir via save_cwd/restore_cwd.

2003-03-08  Jim Meyering  <jim@meyering.net>

	* xnanosleep.c: Don't use `defined' in a #define directive.

2003-03-07  Jim Meyering  <jim@meyering.net>

	* Makefile.am (libfetish_a_SOURCES): Remove mmap-stack.h.

	* mmap-stack.c, mmap-stack.h: Remove files.

	* getcwd.c: #undef getcwd only after *all* included header files.
	Declare getcwd unconditionally.  The problem was that same.h
	included config.h, and that defined getcwd to rpl_getcwd a second
	time (after the original #undef), and led to the rpl_getcwd
	function calling itself endlessly.  This was the cause of at least
	the `du' test failures on IRIX 6.5, reported by Nelson Beebe.

	* same.h (same_name): Remove unnecessary inclusion of config.h.
	It also happened to lead to infinite recursion in getcwd.c.
	(PARAMS): Remove definition and use.

	* save-cwd.c (restore_cwd): Remove two parameters.
	Simplify.  Don't call error upon failure.  Let callers do that.

	user-supplied callback, once for the current directory before calling
	ftw_dir, in case that part of the hierarchy should be pruned.

	(ftw_startup): Likewise.

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

	* ftw.c (lstat) [!_LIBC && !LSTAT_FOLLOWS_SLASHED_SYMLINK]:

	* unlocked-io.h: New file, but with proper copyright notice and
	attribution.  Note: this is *not* the same as the file in gnulib.
	This uses #if HAVE_FUNC_UNLOCKED for each `FUNC', rather than

	macro in ../m4/jm-glibc-io.m4.  Modulo comments, this file still
	contains exactly what was generated by gen-uio.

	* strdup.c (strdup): Merge in changes from gnulib; mainly to
	use memcpy rather than strcpy.

	* strcspn.c: Update from gnulib.

	* sig2str.c (str2signum): Use unsigned, not size_t, for type of index.

	* quotearg.c: Use `"'s when including quotearg.h and xalloc.h,
	not the `<...>' notation.
	Include <errno.h> and declare errno if necessary.

	* README: Update from gnulib.

2002-11-20  Paul Eggert  <eggert@twinsun.com>

	Merge argmatch cleanups from Bison.  Assume C89.

	* argmatch.c: Include config.h here, not in argmatch.h.
	Include stdlib.h, for EXIT_FAILURE.
	Always include <string.h>, since we assume C89.
	(EXIT_FAILURE): Remove pre-C89 bug workaround.
	* argmatch.h: Do not include <config.h> or <sys/types.h>.
	Include <stddef.h> instead, since it's all we need for size_t.
	(PARAMS): Remove.  All uses removed.
	(ARRAY_CARDINALITY): Do not bother to #undef.
	(ARRAY_CARDINALITY, ARGMATCH, ARGCASEMATCH, invalid_arg,
	ARGMATCH_VALID, XARGMATCH, XARGCASEMATCH):
	Remove unnecessary parentheses.
	(ARGMATCH_VALID, XARGMATCH, XARGCASEMATCH):
	Insert necessary parentheses.
	(ARGMATCH_CONSTRAINT, ARGMATCH_VERIFY): New macros.

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

	Be careful not to clobber errno.
	* quotearg.c (quotearg_buffer_restyled): If mbrtowc returns
	`(size_t) -1' (at which point it would also set errno to EILSEQ),
	then restore errno to its previous value.
	Reported by Phillip Jones via Tim Waugh as
	https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=76334.

	Avoid a link-time failure on some Linux systems.
	* mktime.c (STATIC): Define to be empty (_LIBC) or `static' (otherwise).
	(__mon_yday): Declare with the STATIC attribute.
	(__mktime_internal): Likewise.
	Based on a report from Greg Schafer.

2002-11-14  Jim Meyering  <jim@meyering.net>

	* long-options.c: Don't include libintl.h, and don't define `_' --
	they're not used.
	* same.c: Likewise.

2002-11-10  Jim Meyering  <jim@meyering.net>

	* raise.c: New file.

2002-11-08  Paul Eggert  <eggert@twinsun.com>

	* human.c (human_readable): Revamp to avoid warning about unused
	variable 'amt'.  Unfortunately this means using some gotos.

2002-11-08  Jim Meyering  <jim@meyering.net>

	* human.c (human_readable): Avoid warnings from gcc -Wshadow.

2002-11-06  Jim Meyering  <jim@meyering.net>

	New files, taken from GNU tar.

	* human.c, human.h: Rewrite to support locale-specific
	notations like thousands separators.
	Specify what includer of include.h must include beforehand.
	(human_group_digits, human_suppress_point_zero, human_autoscale,
	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.

2002-10-13  Jim Meyering  <jim@meyering.net>

	* xnanosleep.c (initialized): Remove declaration now that it's unused.

2002-10-12  Paul Eggert  <eggert@twinsun.com>

	* xnanosleep.c: There's no need to futz with the rounding mode,
	since the code should work properly even in the default rounding mode.
	(<fenv.h>): Do not include.
	(#pragma STDC FENV_ACCESS ON): Remove.
	(xnanosleep): Don't futz with rounding state.

2002-10-06  Jim Meyering  <jim@meyering.net>

	* safe-read.c (safe_read): Change type of function
	from ssize_t to size_t.

2002-09-28  Jim Meyering  <jim@meyering.net>

	* makepath.c (make_path): Restore umask *before* creating the final
	component.

2002-09-25  Paul Eggert  <eggert@twinsun.com>

	* fsusage.c [! HAVE_INTTYPES_H && HAVE_STDINT_H] Include <stdint.h>.
	(UINTMAX_MAX) [!defined UINTMAX_MAX]: New macro.
	(PROPAGATE_ALL_ONES): Work even if X is unsigned and narrower than
	int.  Work more efficiently if X is the same width as uintmax_t.
	Do not compare X to -1, to avoid bogus compiler warning.
	(get_fs_usage): (uintmax_t) -1 -> UINTMAX_MAX to avoid a cast.
	Don't assume that f_frsize and f_bsize are the same type.

2002-09-25  Jim Meyering  <jim@meyering.net>

	* fsusage.c: Remove unneeded parentheses around operands of `defined'.

	* safe-read.c (safe_read): Make comment more precise:
	upon error, it returns -1.

2002-09-22  Jim Meyering  <jim@meyering.net>

	* makepath.c (make_path): Minor reformatting.

2002-09-14  Paul Eggert  <eggert@twinsun.com>

	* xnanosleep (xnanosleep): Return -1 on failure, not 1,
	for consistency with nanosleep.  Check errno after nanosleep
	returns -1.

2002-09-11  Jim Meyering  <jim@meyering.net>

	* xnanosleep.c, xnanosleep.h: New files, factored out of sleep.c.
	* Makefile.am (libfetish_a_SOURCES): Add them.

2002-09-04  Jim Meyering  <jim@meyering.net>

	* addext.c (addext): Add a cast to avoid gcc's warning about
	`comparison between signed and unsigned'.

	* sig2str.c (str2signum, sig2str): Declare loop index variables to be
	of type size_t so that they match type of upper bound, thus avoiding
	warning about `comparison between signed and unsigned'.

2002-08-31  Jim Meyering  <jim@meyering.net>

	* mktime.c: Update from GNU libc.
	* obstack.c: Likewise.
	* getopt.c: Likewise.
	* getopt1.c: Likewise.

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.

	* posixtm.h (posixtime): Return bool instead of time_t, so
	that we can return (time_t) -1 successfully.
	* posixtm.c: Likewise.
	[HAVE_STDBOOL_H]: Include <stdbool.h>.
	(bool, false, true) [!HAVE_STDBOOL_H]: New type.
	(t): Remove static var.
	(year, posix_time_parse): Now takes struct tm * arg to modify, instead
	of static var.  All uses changed.
	(year): Do not reject years before 1900; they can occur with
	64-bit time_t.
	(posix_time_parse): Do not check for out-of-range components;
	that is now the caller's responsibility, since our checks were
	only approximations.
	(posixtime): Use mktime to check for out-of-range components,
	since it knows them exactly.
	If mktime returns (time_t) -1, check whether an error actually occurred
	by invoking localtime on -1.
	(main) [TEST_POSIXTIME]: Check for input data errors, and report
	posixtime failures better.
	Improve the test data (in comments only).

2002-07-27  Jim Meyering  <jim@meyering.net>

	* readutmp.h: If we have both utmpx.h and utmp.h, and there exists
	the utmp.ut_exit member, but not the utmpx.ut_exit member, then
	undefine HAVE_UTMPX_H.  For AIX 4.3.3.  Doing all this in cpp is
	a big kludge; someday we'll put the brains in an autoconf macro.
	(UT_EXIT_E_TERMINATION, UT_EXIT_E_EXIT): Define.

2002-07-20  Jim Meyering  <jim@meyering.net>

	* xmalloc.c: Adjust to work with new autoconf macros, AC_FUNC_MALLOC
	and AC_FUNC_REALLOC: test #ifndef HAVE_MALLOC/HAVE_REALLOC.

	* gettext.h: Upgrade to gettext-0.11.3.

2002-07-13  Bruno Haible  <bruno@clisp.org>

	* xstat.in: Include <string.h>.
	* mountlist.c: #undef MNT_IGNORE before defining it, to avoid warning
	on FreeBSD.

2002-07-09  Jim Meyering  <jim@meyering.net>

	* mountlist.h (ME_DUMMY): Don't count entries of type `auto' as dummy
	ones.  At least on GNU/Linux systems, `auto' means something else.
	From Michael Stone.

2002-07-01  Jim Meyering  <jim@meyering.net>

	* c-stack.c: Include sys/time.h.
	From Volker Borchert.

2002-06-11  Paul Eggert  <eggert@twinsun.com>

	* fnmatch.c, fnmatch_loop.c (WIDE_CHAR_SUPPORT):
	New macro.  Use it uniformly instead of
	(defined HAVE_WCTYPE_H && defined HAVE_WCHAR_H).
	It also uses HAVE_BTOWC, to fix a porting bug on Solaris 2.5.1
	reported by Vin Shelton.

2002-06-22  Jim Meyering  <jim@meyering.net>

	* fnmatch.c (ISASCII, ISPRINT): Undefine, to avoid warning about
	redefinition due to Solaris 2.6's definition in /usr/include/sys/euc.h.

2002-06-22  Paul Eggert  <eggert@twinsun.com>

	* c-stack.h (segv_handler, c_stack_action) [! defined SA_SIGINFO]:
	Do not assume SA_SIGINFO behavior.
	Bug reported by Jim Meyering on NetBSD 1.5.2.

2002-06-22  Jim Meyering  <jim@meyering.net>

	* c-stack.c, c-stack.h: New files, from diffutils-2.8.2.

	* fnmatch_loop.c: New file, from diffutils-2.8.2.
	* fnmatch.c: Update from diffutils-2.8.2.
	* fnmatch_.h: New file.  From diffutils-2.8.2.
	* fnmatch.h: Remove file.

2002-06-18  Paul Eggert  <eggert@twinsun.com>

	* file-type.h: Report an error if neither S_ISREG nor
	S_IFREG is defined, instead of using a test specific to glibc
	2.2.  This should be safe, since POSIX requires S_ISREG and
	Unix Version 7 had S_IFREG.  We don't need to check for
	<sys/types.h> since we don't use any symbols that it defines.

2002-06-15  Jim Meyering  <jim@meyering.net>

	* file-type.h (FILE_TYPE_H): Guard entire contents with #ifndef.
	For GNU libc 2.2 and newer, ensure that <sys/types.h> and <sys/stat.h>
	have been included before this file.

2002-06-13  Richard Dawe  <richdawe@bigfoot.com>

	* Makefile.am (lstat.c, stat.c, .sin.sed): Use t-$@, rather than $@-t,
	so that each temporary file name is unique and valid in the first
	8 characters, for operation under DOS.

2002-06-15  Jim Meyering  <jim@meyering.net>

	Work even with DJGPP 2.03, which lacks support for symlinks.
	From Richard Dawe.
	* xstat.in (S_ISLNK): Define to 0 if neither S_ISLNK nor S_IFLNK
	is defined.
	* lchown.c (S_ISLNK): Likewise.

2002-06-14  Jim Meyering  <jim@meyering.net>

	* file-type.h: Use the version from diffutils-2.8.2.
	* file-type.c: Likewise.

2002-05-27  Jim Meyering  <jim@meyering.net>

	Fix a problem seen only on nonconforming systems whereby ls.c's
	use of localtime, and then of gettimeofday would cause trouble:
	the localtime call used to initialize rpl_gettimeofday's save
	mechanism would clobber ls's current local time information so
	that in any long listing the first file would always be listed
	with date 1970-01-01.  Analysis by Volker Borchert.

	* gettimeofday.c (localtime): Undefine.
	(rpl_localtime): New function.

2002-05-22  Jim Meyering  <jim@meyering.net>

2002-04-29  Paul Eggert  <eggert@twinsun.com>

	* hard-locale.c: Upgrade to version used in GNU Diffutils 2.8.1.

2002-04-28  Paul Eggert  <eggert@twinsun.com>

	* sig2str.h (SIGNUM_BOUND): Do not use WTERMSIG, to avoid
	depending on <sys/wait.h> and WTERMSIG.  Default to 64 instead
	of 127, since 64 is the largest conceivable number for ancient
	nonstandard hosts.
	* sig2str.c: Do not include <sys/wait.h>; no longer needed.

2002-04-28  Jim Meyering  <jim@meyering.net>

	* sig2str.c (WTERMSIG): Remove definition (unused).

2002-04-28  Paul Eggert  <eggert@twinsun.com>

	* sig2str.h, sig2str.c: New files.
	* Makefile.am (libfetish_a_SOURCES): Add sig2str.h.

2002-04-24  Jim Meyering  <jim@meyering.net>

	* gettext.h: New file, from Gettext.

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

	* dirfd.h (dirfd): Elide prototype if dirfd is a macro.

2002-03-10  Jim Meyering  <jim@meyering.net>

	* makepath.c (make_path): Remove a comma from a diagnostic.
	Suggestion from Santiago Vila.

2002-03-08  Jim Meyering  <jim@meyering.net>

	* rename.c: Mention that this wrapper is needed also on
	mips-dec-ultrix4.4 systems.

2002-03-02  Jim Meyering  <jim@meyering.net>

	* gettime.c (gettime): Test HAVE_CLOCK_GETTIME,
	not HAVE_CLOCK_SETTIME.

2002-02-27  Paul Eggert  <eggert@twinsun.com>

	* nanosleep.h: Rename to....
	* timespec.h: New name for nanosleep.h.  All uses changed.

	* Makefile.am (libfetish_a_SOURCES): Add acl.h, acl.c.

2002-02-24  Jim Meyering  <jim@meyering.net>

	* strnlen.c (strnlen): Define-away/undef so that an inconsistent
	prototype in string.h (on at least AIX4.3.2.0 w/gcc-2.95.3) doesn't
	cause trouble.  Reported by Nelson Beebe.

2002-02-23  Paul Eggert  <eggert@twinsun.com>

	* path-concat.c (xpath_concat): Reorder code to pacify
	compilers that don't know that xalloc_die never returns.

2002-02-20  Jim Meyering  <jim@meyering.net>

	* getdate.c: Regenerate using bison-1.33.

2002-02-15  Paul Eggert  <eggert@twinsun.com>

	* posixver.c, posixver.h: New files.

2002-01-22  Jim Meyering  <jim@meyering.net>

	* Makefile.am (Makefile): Don't depend on $(BUILT_SOURCES).
	Otherwise, some versions of automake would omit the rule that makes
	Makefile from Makefile.in.

2001-01-21  Paul Eggert  <eggert@twinsun.com>

	* xmemcoll.h, xmemcoll.c: New files.

	All callers changed.
	(quoting_options_from_style): New function.
	(quotearg_n_style): Use it.

2002-01-16  Jim Meyering  <jim@meyering.net>

	* getdate.y: Add three semicolons, each just before a closing brace.
	Bison (as of version 1.31) no longer papers over that mistake.

2002-02-14  Paul Eggert  <eggert@twinsun.com>

	* backupfile.c (ISDIGIT): Comment fix.

	not silently exit merely because the output buffer happens to
	have nothing pending.

2001-12-18  Paul Eggert  <eggert@twinsun.com>

	See the big note in ../ChangeLog.
	* human.c (suffixes): Prefer K to k for 1024.
	(generate_suffix_backwards): New function.
	(human_readable_inexact): Use it.
	* xstrtol.c (__xstrtol): If there is no number but there
	is a valid suffix, assume 1.  "MB" now means decimal, "MiB" binary.
	Accept 'K' as well as 'k'.

2001-12-15  Jim Meyering  <jim@meyering.net>

	* regex.h (__restrict_arr): Update from libc.

	* mountlist.h (ME_REMOTE): Recognize file systems of type smbfs
	as `remote' if the name starts with `//'.  Suggested by Michael Stone.
	(STREQ): Define.

2001-12-10  Jim Meyering  <jim@meyering.net>

	* linebuffer.c: Remove explicit declarations of xmalloc and xrealloc,
	Instead, include "xalloc.h".
	(initbuffer): Don't cast xmalloc return value to char*.
	(readline): Reword comment.
	Don't cast xrealloc return value to char*
	Return NULL, not 0.

2001-12-09  Jim Meyering  <jim@meyering.net>

	* modechange.c (mode_compile): Add cast to avoid pedantic warning about
	`signed and unsigned type in conditional expression'.
	* posixtm.c (posix_time_parse): Likewise.

	* xreadlink.c (xreadlink): Add cast to avoid a pedantic warning.

	* readtokens.c (readtoken): Declare an index to be of type unsigned
	to avoid a pedantic warning.

	(getstr): Remove warning-evoking assertions.
	Return -1 if offset parameter is out of bounds.
	Change the type of a local from int to size_t.

	* strftime.c (my_strftime_localtime_r): Include this function
	definition in the `#if ! HAVE_TM_GMTOFF' block.

	* xgethostname.c: Remove declarations of xmalloc and xrealloc.
	Include xalloc.h instead.

2001-12-02  Jim Meyering  <jim@meyering.net>

	* tempname.c: Don't declare getenv, thus reverting the change of
	2001-11-18.  It's no longer necessary, now that stdlib.h is always
	included.

	* regex.c [!__BOUNDED_POINTERS__]: Define away __bounded,
	__unbounded, and __ptrvalue.  Reported by Uwe H. Steinfeld.

2001-11-30  Akim Demaille  <akim@epita.fr>

	before being defined.

2001-11-27  Paul Eggert  <eggert@twinsun.com>

	* quotearg.h (quotearg_n, quotearg_n_style):
	First arg is int, not unsigned.
	* quotearg.c (quotearg_n, quotearg_n_style): Likewise.
	(SIZE_MAX, UINT_MAX): New macros.
	(quotearg_n_options): Abort if N is negative.

	Fix off-by-one typo that caused unnecessary reallocation.

2001-11-27  Jim Meyering  <jim@meyering.net>

	* tempname.c: Merge with version from libc.
	* regex.c: Likewise.

	* tempname.c: Include stdlib.h unconditionally.  On some old systems
	for which STDC_HEADERS is 0, it was not included, resulting in a
	warning about an integer-to-pointer conversion problem with getenv.
	Reported by Volker Borchert.

2001-11-26  Jim Meyering  <jim@meyering.net>

	* gtod.h: Remove file.

	* tempname.c (TMP_MAX): Remove; no longer needed.
	(TEMPORARIES): New macro.
	(__gen_tempname): Use TEMPORARIES rather than TMP_MAX.  This
	removes an artificial limitation (e.g. HP-UX 10.20, where
	TMP_MAX is 17576).

2001-11-17  Jim Meyering  <jim@meyering.net>

	* modechange.c (mode_adjust): Fix error introduced on 1999-04-26
	that made e.g., `chmod a=,o=w,g=o F' cause F to be group readable
	rather than group writable.  Patch by Juan F. Codagnone.

	* readtokens.c: Remove explicit declarations of xmalloc and xrealloc,
	Instead, include "xalloc.h".

	* mountlist.c: Include unlocked-io.h after all system headers.
	Remove explicit declarations of xmalloc, xrealloc,
	and xstrdup.  Instead, include "xalloc.h".

	* argmatch.c, closeout.c, error.c, exclude.c: Include unlocked-io.h.

2001-11-16  Jim Meyering  <jim@meyering.net>

	* physmem.c [HAVE_SYS_PSTAT_H]: Include <sys/pstat.h>.
	(physmem_total) [HAVE_PSTAT_GETSTATIC]: If sysconf couldn't be used to
	determine the amount of total physical memory, use pstat_getstatic.
	HPUX-11 doesn't define _SC_PHYS_PAGES.
	(physmem_available) [HAVE_PSTAT_GETSTATIC && HAVE_PSTAT_GETDYNAMIC]:
	If sysconf couldn't be used to determine the amount of available
	physical memory, use both pstat_getstatic and pstat_getdynamic.
	Based on a patch from Bob Proulx.

2001-11-05  Jim Meyering  <jim@meyering.net>

	* xstat.in (slash_aware_lstat): Correct a misleading comment.

2001-11-03  Jim Meyering  <jim@meyering.net>

	* argmatch.h (ARGMATCH_TO_ARGUMENT): Remove casts of first two args
	in argmatch_to_argument call.

	* dirfd.c (dirfd): Reflect the fact that DIR_TO_FD now takes an
	argument.

	* hard-locale.c (alloca): Define to __builtin_alloca if __GNUC__,
	to avoid a warning if -Wall.

2001-10-21  Paul Eggert  <eggert@twinsun.com>

	* regex.c (uintptr_t): Remove macro and decl; it's config.h's job.

2001-10-21  Jim Meyering  <jim@meyering.net>

	* obstack.c (_): Honor the setting of ENABLE_NLS.  Otherwise,
	this code would end up calling gettext even in packages built
	with --disable-nls.
	* getopt.c (_): Likewise.
	* regex.c (_): Likewise.

2001-10-20  Paul Eggert  <eggert@twinsun.com>

	* error.c (strerror_r): Do not declare unless !_LIBC.

	(strerror): Check for HAVE_DECL_STRERROR before declaring.
	(private_strerror): Use prototypes, not old-style function definition.
	(print_errno_message): New function.
	Support the POSIX 'int'-flavored strerror_r, as well as the traditional
	char*-flavored one.
	(error_tail, error, error_at_line): Use it.

2001-10-11  Jim Meyering  <jim@meyering.net>

	* argmatch.c (argmatch_invalid): Use quotearg_n_style (0, ...
	and quote_n (1, ... to avoid clobbering a buffer.

2001-10-05  Jim Meyering  <jim@meyering.net>

	* Makefile.am: (libfetish_a_SOURCES): Add hash-pjw.c and hash-pjw.h.
	* hash-pjw.c: New file (factored out of fileutils' remove.c).

	a boolean context.

2001-09-28  Paul Eggert  <eggert@twinsun.com>

	Fix bug reported by Petter Reinholdtsen for HP-UX 10.20, which
	#defines strtoimax.  Also treat the other strto* functions
	like strtoimax.

	* xstrtol.c (strtol): Do not declare if HAVE_DECL_STRTOL.
	(strtoul): Do not declare if HAVE_DECL_STRTOUL.
	(strtoimax, strtoumax): Do not declare if already defined as a macro.

2001-09-26  Jim Meyering  <jim@meyering.net>

	Most macros in unlocked-io.h had the wrong number of arguments.
	* gen-uio: New script.
	(USE_UNLOCKED_IO): Define to 1 if not already defined.
	* unlocked-io.hin: Remove file.
	* Makefile.am (unlocked-io.h): Rewrite to use a separate script,
	rather than trying to embed it here.
	(EXTRA_DIST): Add gen-uio.  Remove unlocked-io.hin
	Reported by Padraig Brady.

2001-09-25  Volker Borchert  <bt@teknon.de>

2001-09-20  Jim Meyering  <jim@meyering.net>

	* xstrtol.c (strtoimax): Guard declaration with
	`#if !HAVE_DECL_STRTOIMAX', rather than just `#ifndef strtoimax'.
	The latter fails because some systems (at least rs6000-ibm-aix4.3.3.0)
	have their own, conflicting declaration of strtoimax in sys/inttypes.h.
	(strtoumax): Likewise, for completeness (it wasn't necessary).

2001-09-06  Paul Eggert  <eggert@twinsun.com>

	* strtoimax.c (HAVE_LONG_LONG):
	Redefine to HAVE_UNSIGNED_LONG_LONG if unsigned.

	* mkdir.c: New file.

2001-09-04  Paul Eggert  <eggert@twinsun.com>

	fix the HAVE_GETCWD_NULL code to behave more like the
	!HAVE_GETCWD_NULL code used to.

	Include "xalloc.h".
	(xgetcwd): Do not return NULL when memory is exhausted; instead,
	invoke xalloc_die.

2001-09-04  Paul Eggert  <eggert@twinsun.com>

	* xreadlink.c (xreadlink): Omit size_t* arg.  All uses changed.
	Use ssize_t, not int, to store result of readlink.
	Check for ssize_t overflow as well as size_t overflow,
	as POSIX says the result of readlink is implementation-defined
	when ssize_t overflows.
	Remove unnecessary cast to char*.
	Use free+malloc instead of realloc, as the storage doesn't need
	to be preserved and it's clearer and can be more efficient that way.
	(SIZE_MAX, SSIZE_MAX): New macros, if <limits.h> doesn't declare.
	* xreadlink.h (xreadlink): Update prototype.

2001-09-03  Paul Eggert  <eggert@twinsun.com>

	like the HAVE_GETCWD_NULL code.
	Include pathmax.h if not HAVE_GETCWD.
	Do not include xalloc.h.
	(INITIAL_BUFFER_SIZE): New symbol.
	Do not use xmalloc / xrealloc, since the caller is responsible for
	handling errors.  Preserve errno around `free' during failure.
	Do not overrun buffer when using getwd.

2001-09-03  Paul Eggert  <eggert@twinsun.com>

	* xgetcwd.c (xgetcwd): Use HAVE_GETCWD_NULL, not (defined
	__GLIBC__ && __GLIBC__ >= 2), to decide whether to use getcwd (NULL, 0).

2001-09-02  Jim Meyering  <jim@meyering.net>

	* error.c: Update from GNU libc.

2001-09-01  Jim Meyering  <jim@meyering.net>

	* xreadlink.h: New file.
	* Makefile.am (libfetish_a_SOURCES): Add xreadlink.c and xreadlink.h.

	* regex.c (uintptr_t) [!_LIBC]: Define to private_uintptr_t, so it
	doesn't conflict with sparc Solaris 7's definition in
	/usr/include/sys/int_types.h.

	* exclude.c: Use `""', not `<>' to #include non-system header files.
	(fnmatch_no_wildcards): Rewrite not to use function names, strcasecmp
	and strncasecmp as r-values.  Unixware didn't have declarations.

2001-08-31  Jim Meyering  <jim@meyering.net>

	* xgetcwd.c (xgetcwd): Reorganize to avoid some duplication.
	Use an initial, malloc'd, buffer of length 128 rather than
	a statically allocated one of length 1024.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

	* xgetcwd.c: Don't include pathmax.h.
	Include stdlib.h and unistd.h if available.
	Include xalloc.h.
	(xmalloc, xstrdup, free): Remove decls.
	(xgetcwd): Don't assume sizes fit in unsigned.
	Check for overflow when computing sizes.
	Simplify reallocation code.

2001-08-28  Paul Eggert  <eggert@twinsun.com>

	* Makefile.am (libfetish_a_SOURCES): Remove strtoxmax.c.

	* strtoimax.c: Renamed from strtoxmax.c, removing the
	old strtoimax.c.

	Also, make the following further changes to make this file's
	configuration more similar to that of strtol.c:
	(UNSIGNED): Renamed from STRTOUXMAX_UNSIGNED.  All uses changed.
	(strtoumax, uintmax_t, strtoull, strtol): Remove.
	(intmax_t, strtoimax, strtol, strtoll): New macros, if UNSIGNED.
	(strtoimax): Renamed from strtoumax.  All uses of unsigned values
	changed to signed values.

	And make the following changes as well:
	Fix copyright notice, as 1999 was missing.
	(verify): New macro.
	(strtoimax): Check sizes at compile-time, not run-time.
	Prefer strtol to strtoll if both work.
	(main): Remove; it was not that useful and was a pain to maintain.

	* strtoumax.c: Include strtoimax.c, not strtouxmax.c.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

	* savedir.c (savedir): Remove size parameter, as POSIX says that
	a directory's st_size can have an arbitrary value, so the old
	usage could waste an arbitrary amount of memory.  All uses
	changed.
	* savedir.h: Update prototype.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

	* xstrtol.c (strtoimax): New decl.

2001-08-28  Paul Eggert  <eggert@twinsun.com>

	LONGINT_INVALID_SUFFIX_CHAR.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

	* quotearg.c: BSD/OS 4.1 wchar.h requires FILE and struct
	tm to be declared.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

	* hash.c: Remove '2001' from copyright notice.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

	* full-write.h: New file.
	* Makefile.am (libfetish_a_SOURCES): Add full-write.h.
	* full-write.c: Correct credits, as cccp.c no longer
	exists and anyway it was so heavily changed from the old cccp
	code as to be unrecognizable.  Include full-write.h.
	(full_write) Return size_t, with short writes meaning failure.
	All callers changed.  This fixes a bug with large buffers
	on 64-bit hosts.
	* utime.c: Include full-write.h.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

	Merge 'exclude' changes from tar 1.13.22.
	This fixes one or two unlikely storage allocation overflow bugs,
	but doesn't change user-visible behavior otherwise.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

	* exclude.c (bool): Declare, perhaps by including stdbool.h.
	(<sys/types.h>): Include only if HAVE_SYS_TYPES_H.
	(<stdlib.h>, <string.h>, <strings.h>, <inttypes.h>, <stdint.h>):
	Include	if available.
	(<xalloc.h>): Include
	(SIZE_MAX): Define if <stdint.h> or <inttypes.h> doesn't.
	(verify): New macro.  Use it to verify that EXCLUDE macros do not
	collide with FNM macros.
	(struct patopts): New struct.
	(struct exclude): Use it, as exclude patterns now come with options.
	(new_exclude): Support above changes.
	(new_exclude, add_exclude_file):
	Initial size must now be a power of two to simplify overflow checking.
	(free_exclude, fnmatch_no_wildcards): New function.
	(excluded_filename): No longer requires options arg, as the options
	are determined by add_exclude.  Now returns bool, not int.
	(excluded_filename, add_exclude):
	Add support for the fancy new exclusion options.
	(add_exclude, add_exclude_file): Now takes int options arg.
	Check for arithmetic overflow when computing sizes.
	(add_exclude_file): xrealloc might modify errno, so don't
	realloc until after errno might be used.

	* exclude.h (EXCLUDE_ANCHORED, EXCLUDE_INCLUDE,EXCLUDE_WILDCARDS):
	New macros.
	(free_exclude): New decl.
	(add_exclude, add_exclude_file): Now takes int options arg.
	(excluded_filename): No longer requires options arg, as the options
	are determined by add_exclude.  Now returns bool, not int.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

	* alloca.c (alloca): Arg is of type size_t, not unsigned.

2001-08-27  Jim Meyering  <jim@meyering.net>

	* Makefile.am (libfetish_a_SOURCES): Add strtoxmax.c

	* version-etc.c (N_): Remove definition.
	Revert most of last change.
	Instead, simply don't mark the `Copyright...' string for translation.
	Based on advice from Paul Eggert.

	* strtoxmax.c: Tweak comment.

2001-08-26  Jim Meyering  <jim@meyering.net>

	* version-etc.c (version_etc_copyright_fmt): Replace literal year
	of copyright with `%s' so translators don't get an untranslated
	message in 2002.

	(version_etc): Use fprintf rather than fputs.
	Suggestion from Ulrich Drepper.

	* Makefile.am (libfetish_a_SOURCES): Add xstrtoimax.c.

	* strtoll.c: New file, from GNU libc.
	* xstrtoimax.c: New file.

	* xstrtol.h: Add xstrtoimax.
	* strtoumax.c: New file.  Simply include "strtoumax.c".
	* strtoimax.c: New file.  Likewise, but first define STRTOUXMAX_SIGNED.

	* strtoumax.c: Factor to work both for unsigned and signed types, ...
	* strtoxmax.c: ... then renamed to this.

2001-08-13  Paul Eggert  <eggert@twinsun.com>

	* Makefile.am (unlocked-io.h): Do not append "_unlocked" twice.
	Port to Solaris 8, where 'sed' requires a space after the 'r'
	command, and where sh dislikes "$/".  Clean up the spacing a bit.
	Redirect output to $tmp just once.

2001-08-12  Paul Eggert  <eggert@sic.twinsun.com>

	* addext.c (<errno.h>): Include.
	(errno): Declare if not defined.
	(addext): Work correctly when pathconf returns -1 and leaves
	errno alone because there is no limit.  Also, work even if
	pathconf returns a value greater than SIZE_MAX.

2001-08-12  Jim Meyering  <jim@meyering.net>

	* xgetcwd.c (xgetcwd) [defined __GLIBC__ && __GLIBC__ >= 2]:

	two unnecessary .h files.

2001-06-11  Jim Meyering  <jim@meyering.net>

	* regex.c: Update from GNU libc.

2001-05-27  Jim Meyering  <jim@meyering.net>

	* Makefile.am (libfetish_a_SOURCES):
	Add strftime.c, since we now compile it on all hosts.

	(emacs_strftimeu): Renamed from emacs_strftime,
	with extra ut argument.

2001-05-11  Paul Eggert  <eggert@twinsun.com>

	dirname code cleanup.  base_name now behaves more compatibly
	with POSIX basename when given file names that have trailing
	slashes, and similarly for dir_name.  Add new primitives
	base_len and dir_len.  Put the directory-name-related decls
	into dirname.h.

	* addext.c (ISSLASH, base_name): Remove; now in dirname.h.
	* backupfile.c (base_name): Likewise.
	* basename.c (FILESYSTEM_PREFIX_LEN, PARAMS, ISSLASH): Likewise.
	* dirname.c (FILESYSTEM_PREFIX_LEN, ISSLASH): Likewise.
	* makepath.c (strip_trailing_slashes): Likewise.

	* backupfile.c: Likewise.

	* addext.c (addext): Use base_len to trim redundant
	trailing slashes instead of doing it ourselves.
	But do not trim the last slash if it is not redundant.

	* backupfile.c (find_backup_file_name,
	max_backup_version): Use base_len instead of rolling it ourselves.
	Handle the case of "" and (on DOS) "C:" correctly.

	* basename.c: Do not include <stdio.h>, <assert.h>; no longer needed.
	Include <string.h>, <dirname.h>.
	(base_name): Allow file names ending in slashes, other than names
	that are all slashes.  In this case, return the basename followed
	by the slashes.  This is more general, and can be used in places
	where the original base_name purposely had an assertion failure.
	(base_len): New function.

	* dirname.c: Include <string.h> instead of <stdlib.h>.
	Do not include <assert.h>; no longer needed.
	Include xalloc.h.
	(memrchr): Remove decl.
	(dir_name_r): Remove.
	(dir_len): Renamed from dirlen.  All callers changed.
	Rewrite in terms of base_name, for simplicity and consistency.

	New macros.
	(base_name, base_len, dir_len, strip_trailing_slashes): New decls.

	(same_name): Handle the case where the basename ends in trailing '/'.

	* stripslash.c (strip_trailing_slashes): Return nonzero if
	a slash was stripped.  Do not strip the last slash after a
	file system prefix.

2001-04-08  Jim Meyering  <jim@meyering.net>

	* getdate.y (get_date): Set tm_isdst to -1 to ensure that it is
	recomputed; that's necessary when the offset spans a DST transition.
	Patch by David J. MacKenzie.  Reported by Hon-Yin Kok.

2001-04-02  Jim Meyering  <jim@meyering.net>

	* regex.h, regex.c: Update from GNU libc.

2001-02-25  Paul Eggert  <eggert@twinsun.com>

	The mkstemp replacement is taken from glibc 2.2.2, with some
	portability fixes for use outside glibc, as follows:

	* tempname.c (struct_stat64): New macro.
	(direxists, __gen_tempname): Use it.
	This avoids a portability problem with Solaris 8.

	before using mbrtowc.

2001-02-17  Jim Meyering  <jim@meyering.net>

	* regex.c: Update from libc.

2001-02-16  Paul Eggert  <eggert@twinsun.com>

	local `inptr' to avoid warning with some system declarations of iconv.

2000-12-29  Paul Eggert  <eggert@twinsun.com>

	* modechange.c: Do not assume that mode_t uses the
	traditional octal encoding.  E.g. "chmod 1 FOO" should set
	the other-execute bit of FOO even if S_IXOTH != 1.

	(SUID, SGID, SVTX, RUSR, WUSR, XUSR, RGRP, WGRP, XGRP, ROTH,
	WOTH, XOTH, ALLM): New macros.

	Use them.
	(S_ISGID): Fix typo; it was defaulting to the same value as S_ISUID.
	(S_IRWXU, S_IRWXG, S_IRWXO): Specify defaults in terms of the above.
	(mode_compile):
	No need to use uintmax_t; unsigned long is long enough.
	Don't bother to get suffix since we don't use it.

2000-12-24  Jim Meyering  <jim@meyering.net>

	* hash.c (is_prime): Return explicit boolean values.
	(hash_get_first): Return NULL to appease Irix5.6's 89.

	Based mostly on a patch from Prashant TR.

2000-12-16  Jim Meyering  <jim@meyering.net>

	This bug had a serious impact on chown: `chown N:M FILE' (for integer
	N and M) would have treated it like `chown N:N FILE'.

2000-10-31  Bruno Haible  <haible@clisp.cons.org>

	* strftime.c (my_strftime): Do not invoke mbrlen with a
	size of (size_t) -1; it's not portable.

2000-11-17  Akim Demaille  <akim@epita.fr>

	* obstack.h: Formatting changes.
	(obstack_grow, obstack_grow0): Don't cast WHERE at all: that would
	prevent type checking.
	(obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
	cast the value to (void *): assigning a `foo *' to a `void *'
	variable is valid.

2000-11-02  Vesselin Atanasov  <vesselin@bgnet.bg>

	* fnmatch.c: Do not comment out all the code if we are using

2000-10-30  Paul Eggert  <eggert@twinsun.com>

	* error.h, getline.h, modechange.h:

	changed this year other than in the copyright notice.

	* xalloc.h: Add "2000" to Copyright line, as this file
	was changed this year.

	* strftime.c: Update from libc.

2000-10-25  Jim Meyering  <jim@meyering.net>

	* obstack.c: Update from libc.

2000-10-23  Jim Meyering  <jim@meyering.net>

	* hard-locale.c (hard_locale): Revert last change -- it was simply
	wrong.  That set_locale call must not have any side effects.
	From Paul Eggert.

2000-10-22  Jim Meyering  <jim@meyering.net>

	* md5.c (md5_process_block) [OP]: Use `rol', not CYCLIC.
	[CYCLIC]: Remove now-unused definition.

	think it should be used as a general replacement for isascii.
	* fnmatch.c: Likewise.
	* mbswidth.c: Likewise
	* regex.c: Likewise.

	Don't use atoi.
	* userspec.c: Include sys/param.h and limits.h.

2000-08-03  Greg McGary  <greg@mcgary.org>

	* regex.c (SET_HIGH_BOUND, MOVE_BUFFER_POINTER,

	(EXTEND_BUFFER): Use them.

2000-08-01  Jim Meyering  <jim@meyering.net>

	* dirname.c (ISSLASH): Define.
	(BACKSLASH_IS_PATH_SEPARATOR): Define.
	(dir_name) [BACKSLASH_IS_PATH_SEPARATOR]: Handle the case in which

2000-07-31  Paul Eggert  <eggert@twinsun.com>

	* quotearg.c (quotearg_n_options): Don't make the initial
	slot vector a constant, since it might get modified.

2000-07-31  Jim Meyering  <jim@meyering.net>

	* xmalloc.c: Use `virtual memory exhausted', not `Memory exhausted'.
	* obstack.c (print_and_abort): Likewise.

2000-07-30  Paul Eggert  <eggert@twinsun.com>

	* quotearg.c (quotearg_n_options): Preallocate a slot 0
	buffer, so that the caller can always quote one small
	component of a "memory exhausted" message in slot 0.
	From a suggestion by Jim Meyering.

2000-07-30  Jim Meyering  <jim@meyering.net>

	(wcwidth) [!HAVE_DECL_WCWIDTH]: Declare.

2000-07-23  Paul Eggert  <eggert@twinsun.com>

	* quotearg.c:
	Include <wchar.h> even if ! (HAVE_MBRTOWC && 1 < MB_LEN_MAX),
	so that mbstate_t is always defined.

	Do not inspect MB_LEN_MAX, since it's incorrectly defined to
	be 1 in at least one GCC installation, and this configuration
	error is likely to be common.  Ignoring MB_LEN_MAX hurts
	performance on hosts that have mbrtowc but have only unibyte
	locales, but I assume these hosts are rare.

2000-07-23  Paul Eggert  <eggert@twinsun.com>

	and "{RIGHT QUOTATION MARK}" msgids.

2000-07-05  Paul Eggert  <eggert@twinsun.com>

	The old behavior of quoting `like this' doesn't look good with
	newer, ISO-style fonts.  See:
	http://www.cl.cam.ac.uk/~mgk25/ucs/quotes.html

	Instead, quote "like this" by default.  Let the translator
	tailor the locale-specific quoting behavior by providing
	translations for {LEFT QUOTATION MARK} and {RIGHT QUOTATION MARK}.

	* xgetcwd.c (xgetcwd): If the required pathname length is smaller
	than 1024, return a memory chunk of least possible size, instead

	(textint): New typedef.
	(parser_control): Member year changed from int to textint.
	All uses changed.
	(YYSTYPE): Removed; replaced by %union with int and textint members.
	(tDAY, tDAY_UNIT, tDAYZONE, tHOUR_UNIT, tID, tLOCAL_ZONE, tMERIDIAN,
	tMINUTE_UNIT, tMONTH, tMONTH_UNIT tSEC_UNIT, tSNUMBER, tUNUMBER,
	tYEAR_UNIT, tZONE, o_merid): Now of type <intval>.
	(tSNUMBER, tUNUMBER): Now of type <textintval>.
	(date, number, to_year): Use width of number in digits, not its value,
	to determine whether it's a 2-digit year, or a 2-digit time.
	(yylex): Store number of digits of numeric tokens.
	Reported by John Kendall.

	(parser_control): Changed from struct parser_control to typedef (for

	* getpagesize.h (getpagesize): Port to VMS for Alpha;
	adapted from changes to grep getpagesize.h by Martin P.J. Zinser.

2000-02-12  Jim Meyering  <jim@meyering.net>

	* userspec.c (ISDIGIT): Define it.
	(isdigit): Remove definition.
	(is_number): Use ISDIGIT, not isdigit.
	<libintl.h>: Include.
	(_ and N_): Define.
	(parse_user_spec): Mark translatable strings.

2000-02-10  Jim Meyering  <jim@meyering.net>

	With these changes, nanosleep.[ch] are finally enough like the other
	lib/* replacement files to compile on a few more losing systems.

	* nanosleep.h: Don't include config.h.
	Remove prototype from declaration of nanosleep.
	(PARAMS): Remove now-unneeded definition.
	* nanosleep.c: #undef nanosleep.
	(rpl_nanosleep): Rename from nanosleep.

2000-02-03  Jim Meyering  <jim@meyering.net>

	* readutmp.c (read_utmp): Guard with `#ifdef UTMP_NAME_FUNCTION',
	rather than with `#if HAVE_UTMPNAME'.

2000-02-01  Jim Meyering  <jim@meyering.net>

	* readutmp.h (UT_USER): Add parens.  From Andreas Schwab.

2000-01-31  Jim Meyering  <jim@meyering.net>

	* nanosleep.h (nanosleep): Guard declaration with
	`#if ! HAVE_DECL_NANOSLEEP'.
	Without this, OFS gets a redeclaration error for rpl_nanosleep, due to
	the declaration in that vendor's sys/timers.h.
	Reported by Christian Krackowizer.

	* quotearg.c (ISASCII): Add #undef and move definition to follow
	inclusion of wctype.h to work around Solaris 2.6 namespace pollution.
	(ISPRINT): Likewise.
	Reported by Tom Tromey.

2000-01-30  Jim Meyering  <jim@meyering.net>

	* readutmp.c (extract_trimmed_name): Use UT_USER instead of hard-coding
	uses of ->ut_name.  The latter doesn't work with new Linux header files
	where only utmpx.ut_user is declared.

	* readutmp.h (UT_USER): Define.

2000-01-23  Jim Meyering  <jim@meyering.net>

	* Makefile.am (libfetish_a_SOURCES): Remove explicit mention of
	obstack.c.

2000-01-22  Jim Meyering  <jim@meyering.net>

	* strtoumax.c: [! HAVE_DECL_STRTOUL]: Declare strtoul.
	[! HAVE_DECL_STRTOULL]: Declare strtoull.
	Required for some AIX systems.  Reported by Christian Krackowizer.
	[TESTING] (main): New function.

	1997-10-17  Eli Zaretskii  <eliz@is.elta.co.il>
	* dirname.c (dir_name): Support for DOS-style file names with drive
	letters.

	* quotearg.c [HAVE_WCTYPE_H]: Include <wctype.h> for decl of iswprint.

	* strverscmp.c (ISDIGIT): Define.
	(strverscmp): Use ISDIGIT, not isdigit.

2000-01-17  Paul Eggert  <eggert@twinsun.com>

	* nanosleep.c (nanosleep):
	Don't use SA_INTERRUPT to decide whether to call sigaction, as
	POSIX.1 doesn't require SA_INTERRUPT and some systems
	(e.g. Solaris 7) don't define it.  Use SA_NOCLDSTOP instead;
	it's been part of POSIX.1 since day 1 (in 1988).

2000-01-17  Jim Meyering  <jim@meyering.net>

	* interlock: Remove unused file.  Reported by François Pinard.

2000-01-16  Paul Eggert  <eggert@twinsun.com>

	* quotearg.c (quotearg_buffer_restyled): Do not quote
	alert, backslash, formfeed, and vertical tab unnecessarily in
	shell quoting style.
