2007-05-31  Jim Meyering  <jim@meyering.net>

	* printf-parse.c, vasnprintf.c, unicodeio.c: Remove local
	copies, so we now get these files from gnulib.

2007-03-20  Jim Meyering  <jim@meyering.net>

	Fix a typo in the handling of %x and %X.
	* vasnprintf.c (VASNPRINTF): When adding 2 to buffer length,
	don't double it.

2007-03-04  Jim Meyering  <jim@meyering.net>

	* vasnprintf.c (VASNPRINTF): Add missing semicolon.

2007-03-02  Jim Meyering  <jim@meyering.net>

	* vasnprintf.c (VASNPRINTF): Remove cast of alloca return value.

2007-03-01  Jim Meyering  <jim@meyering.net>

	Merge in changes from gnulib:
	* vasnprintf.c: Add a comment explaining why coreutils has its own
	version of this file.
	Include <stdint.h>.
	(SIZE_MAX): Remove definition (now, stdint.h covers that).
	(EOVERFLOW): Remove definition (now done via the eoverflow module).
	Update some #ifdef to #if.
	Use HAVE_LONG_LONG_INT, not HAVE_LONG_LONG.
	* printf-parse.c: Likewise.

2007-02-28  Jim Meyering  <jim@meyering.net>

	* tsearch.c: Remove unused file.

2007-02-23  Jim Meyering  <jim@meyering.net>

	* randperm.c (randperm_new): Comment: say that this function
	returns a pointer to malloc'd storage.

2007-02-18  Jim Meyering  <jim@meyering.net>

	* xfts.c: Include <stdlib.h> rather than exit.h, now that stdlib.h
	is guaranteed to provide a valid definition of EXIT_FAILURE.

2007-01-19  Jim Meyering  <jim@meyering.net>

	* .cvsignore, .gitignore: Add sys, as well as more
	bootstrap-inserted file names.

2007-01-14  Jim Meyering  <jim@meyering.net>

	* fchdir-stub.c: Remove file.  No longer needed.

2006-12-03  Jim Meyering  <jim@meyering.net>

	* Makefile.am (libcoreutils_a_SOURCES): Remove xmemcoll.c and
	xmemcoll.h.  Now, they're handled by the gnulib xmemcoll module.

2006-11-22  Paul Eggert  <eggert@cs.ucla.edu>

	* randread.c (__attribute__): Don't define if __attribute__ is
	already defined.  Otherwise, the code won't conform to C99, since
	the macro arg is spelled differently by some include file, and the
	compilation fails with pedantic GCC.

2006-11-22  Jim Meyering  <jim@meyering.net>

	* .cvsignore, .gitignore: Add fstat.c.

2006-11-14  Jim Meyering  <jim@meyering.net>

	* readlink-stub.c, lstat-stub.c: Remove now-unused files.

2006-10-14  Paul Eggert  <eggert@cs.ucla.edu>

	Port sha512sum to hosts where uintmax_t is only 32 bits, e.g.,
	HP/Tandom NonStop OSS circa 2005 has 32-bit uintmax_t, 64-bit intmax_t.
	* u64.h: New file.
	* sha512.c (SWAP, sha512_init_ctx, sha384_init_ctx, sha512_read_ctx):
	(sha384_read_ctx, sha512_conclude_ctx, sha512_process_bytes):
	(sha512_round_constants, F2, F1, sha512_process_block):
	(S0, S1, SS0, SS1, M, R):
	Rewrite to use u64.h instead of assuming uint64_t.
	* sha512.h: Include u64.h rather than stdint.h.
	(rol64): Remove; moved to u64.h and renamed to u64rol.

2006-10-12  Jim Meyering  <jim@meyering.net>

	* Makefile.am (libcoreutils_a_LIBADD): Append $(LIBOBJS),
	to accommodate the latest version of gnulib-tool.
	(libcoreutils_a_DEPENDENCIES): Likewise.
	From Bruno Haible.

2006-10-06  Jim Meyering  <jim@meyering.net>

	Avoid a compiler warning: const'ify and remove a cast.
	* randread.c (struct randread_source) [handler]: Make parameter "const".
	[handler_arg]: Add "const" attribute.
	(randread_error): Make parameter "const".
	(simple_new, randread_set_handler, randread_set_handler_arg): Likewise.
	(randread_new): Remove now-unnecessary cast.
	* randread.h: Adjust prototypes.

2006-09-29  Paul Eggert  <eggert@cs.ucla.edu>

	* .cvsignore: Add openat-proc.c.

2006-09-25  Paul Eggert  <eggert@cs.ucla.edu>

	* .cvsignore: Add fchmodat.c.

2006-09-25  Jim Meyering  <jim@meyering.net>

	* fchmodat.c: Remove file.  gnulib's copy is identical.

2006-09-01  Paul Eggert  <eggert@cs.ucla.edu>

	* .cvsignore: Add fcntl.h, fcntl_.h, inttypes_.h, isapipe.c,
	isapipe.h.

2006-08-25  Paul Eggert  <eggert@cs.ucla.edu>

	* euidaccess-stat.c: Include <config.h> unconditionally, since
	we now assume config.h exists.
	* fchmodat.c: Likewise.
	* fd-reopen.c: Likewise.
	* fdopendir-glibc.c: Likewise.

2006-08-22  Paul Eggert  <eggert@cs.ucla.edu>

	* .cvsignore: Add Makefile.in, getdate.tab.h.
	Remove stat.c, sysexit.h.

2006-08-22  Jim Meyering  <jim@meyering.net>

	* .cvsignore: Add files that are now generated by ../bootstrap.

2006-08-21  Eric Blake  <ebb9@byu.net>

	* Makefile.am (LDADD): Restore this line; it is still needed for
	t-fpending on platforms without __fpending.

2006-08-20  Paul Eggert  <eggert@cs.ucla.edu>

	Add a bootstrap procedure, so that the CVS version contains fewer
	files and we bootstrap the rest from gnulib, gettext, etc.
	* Makefile.am: include gnulib.mk, so that we can remove most of

	* savedir.h: Likewise.

2006-08-16  Paul Eggert  <eggert@cs.ucla.edu>

	* memcoll.c (memcoll): Set errno = 0 in the shortcut case, too.
	Problem and fix reported by Pádraig Brady in
	<http://lists.gnu.org/archive/html/bug-coreutils/2006-08/msg00099.html>.

2006-08-16  Jim Meyering  <jim@meyering.net>

	* fts.c (fts_children): Remove obsolete "// FIXME ..." comment.
	Reported by Bruno Haible.

2006-08-15  Jim Meyering  <jim@meyering.net>

	* at-func.c: New file, with the logic of all emulated at-functions.
	* openat-priv.h: Include <errno.h> and define ENOSYS,

	to the byte which couldn't be converted.
	(re_string_reconstruct): Don't clear valid_raw_len before calling
	re_string_skip_chars.  If wc is WEOF after re_string_skip_chars, set
	tip_context using re_string_context_at.

	2006-05-02  Ulrich Drepper  <drepper@redhat.com>

	* posix/regex.h: g++ still cannot handled [restrict].

	(MOSTLYCLEANFILES): Add arpa/inet.h, arpa/inet.h-t, netinet/in.h,
	netinet/in.h-t, sys/socket.h, sys/socket.h-t.
	(EXTRA_DIST): Add socket_.h.

	* rand-isaac.h: New file.
	* rand-isaac.c: New file, mostly taken from ../src/rand-isaac.c.

2006-07-28  Paul Eggert  <eggert@cs.ucla.edu>

	* modechange.c (mode_compile): Numeric modes now affect setuid and
	setgid on directories only if they set these bits.
	* modechange.h: Remove obsolete comment about masks.

2006-07-22  Paul Eggert  <eggert@cs.ucla.edu>

	* close-stream.c, close-stream.h: New files.

2006-07-16  Paul Eggert  <eggert@cs.ucla.edu>

	* dirchownmod.c, dirchownmod.h, mkancesdirs.c, mkancesdirs.h:
	New files.
	* mkdir-p.c: Don't include alloca.h, stdio.h, sys/types.h,
	unistd.h, string.h, chdir-safer.h, dirname.h, lchmod.h, lchown.h,
	save-cwd.h.  Instead, include dirchownmod.h and mkancesdirs.h.
	(make_dir_parents): New args MAKE_ANCESTOR, OPTIONS, ANNOUNCE,
	MODE_BITS.  Remove options VERBOSE_FMT_STRING, CWD_ERRNO.  All
	callers changed.  Revamp internals significantly, by not
	attempting to create directories that are temporarily more
	permissive than the final results.  Do not attempt to use
	save_cwd/restore_cwd; it isn't worth it for mkdir and install.
	This removes some race conditions, fixes some bugs, and simplifies
	things.  Use new dirchownmod function to do owner and mode changes.
	* mkdir-p.h: Likewise.
	* modechange.c (octal_to_mode): New function.
	(struct mode_change): New member mentioned.
	(make_node_op_equals): New arg mentioned.  All callers changed.
	(mode_compile): Keep track of which mode bits the user has explicitly
	mentioned.
	(mode_adjust): New arg DIR, so that we implement the X op correctly.
	New arg PMODE_BITS, to keep track of which mode bits the user
	mentioned; it treats S_ISUID and S_ISGID speciall.
	All callers changed.
	* modechange.h: Likewise.

2006-07-16  Jim Meyering  <jim@meyering.net>

	* userspec.c (parse_with_separator): Say "invalid spec" rather than
	the sometimes erroneous "cannot get the login group of a numeric UID"
	for a spec like "not-a-username:" or "1:".  Reported by
	suckfish@ihug.co.nz in https://bugzilla.redhat.com/bugzilla/199027.

2006-07-10  Derek R. Price  <derek@ximbiot.com>

	* backupfile.c, dirfd.h, fts.c, getcwd.c:
	Ignore the obsolescent !HAVE_DIRENT_H case.  Consolidate NAMLEN
	macros into the GNU _D_EXACT_NAMLEN.
	* savedir.c:  Likewise.
	(savedirstream): Use _D_EXACT_NAMLEN in preference to strlen.

2006-07-08  Paul Eggert  <eggert@cs.ucla.edu>

	* Makefile.am (stdint.h): FULL_PATH_STDINT_H -> ABSOLUTE_STDINT_H,
	to accommodate update from gnulib.

	Update from gnulib, as follows:

	2006-07-06  Jim Hyslop  <jhyslop@dreampossible.ca>  (tiny change)

	* getaddrinfo.c: Changes to compile under MSVC6: changed

	* wcwidth.h: ...to this new file.

	2006-06-28  Simon Josefsson  <jas@extundo.com>

	* getaddrinfo.c: Try to load ws2_32.dll on Windows, to find the
	functions there.  It will succeed on Windows XP, but on Windows
	2000 and (presumably) earlier, it will fail, and use the internal
	re-implementation.
	(use_win32_p): New function.
	(getaddrinfo): Use strtoul on servname, to support numeric ports.

	2006-05-10  Paul Eggert  <eggert@cs.ucla.edu>

	* sha1.c (rol): Cast right-shift arg to uint32_t to prevent
	unwanted sign propagation, e.g., on hosts with 64-bit int.
	There still are some problems with reeelly weird theoretical hosts
	(e.g., 33-bit int) but it's not worth worrying about now.
	(K1, K2, K3, K4): Remove unnecessary L suffix.

	2006-03-24  Simon Josefsson  <jas@extundo.com>

	* base64.c: Fix problems reported by Eric Blake <ebb9@byu.net>,
	including some doc fixes.
	(base64_encode_alloc): Fix +1 bug on allocation failures.

	* stdint_.h: Include <sys/types.h> after @FULL_PATH_STDINT_H@, for
	MacOS X 10.4.6.  Don't mention <sys/int_types.h>.  Problems
	reported by Mark D. Baushke, one in
	<http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00015.html>.

2006-07-03  Jim Meyering  <jim@meyering.net>

	macro is used before the first cycle_check call.

2006-07-02  Paul Eggert  <eggert@cs.ucla.edu>

	* stdint_.h (intmax_t, uintmax_t): Prefer long to long long if
	both are 64 bits, since this seems to be the tradition, and this
	prevents gcc -Wformat from warning about usages with PRIuMAX.  If
	we ever run into a host that prefers long long to long in this
	case, we'll need another configure-time test.  Problem reported by
	Jim Meyering.

2006-07-02  Paul Eggert  <eggert@cs.ucla.edu>

	* Makefile.am (stdint.h): Sync from gnulib.
	* stdint_.h: Sync from gnulib.

	Autoconf 2.60 says this stuff was obsolete.

2006-06-20  Paul Eggert  <eggert@cs.ucla.edu>

	* openat.c (openat): Use ?:, not if, to work around GCC bug 4210
	<http://gcc.gnu.org/bugzilla/show_bug.cgi?id=4210>.
	Problem reported by Denis Excoffier in
	<http://lists.gnu.org/archive/html/bug-tar/2006-06/msg00023.html>.

2006-06-19  Jim Meyering  <jim@meyering.net>

	Apply this change from gnulib:
	2006-06-16  Eric Blake  <ebb9@byu.net>
	* unsetenv.c [!defined errno]: Assume errno.h declares errno.

2006-06-11  Paul Eggert  <eggert@cs.ucla.edu>

	* getdate.y (__attribute__): Don't define if already defined.
	Problem reported by Larry Jones.
	* utimens.c (__attribute__): Likewise.

2006-06-10  Jim Meyering  <jim@meyering.net>

	Apply this change from gnulib:

	2006-05-30  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>
	            Bruno Haible  <bruno@clisp.org>

	* strndup.c (strndup) [!_LIBC]: Don't undefine macro definition.

2006-06-04  Paul Eggert  <eggert@cs.ucla.edu>

	* regexec.c (group_nodes_into_DFAstates): Fix a buffer overrun
	reported by Andreas Schwab.

2006-05-25  Paul Eggert  <eggert@cs.ucla.edu>

	* tempname.c (small_open, large_open): New macros.
	(__open, __open64) [!_LIBC]: Remove.
	(__gen_tempname): Use small_open and large_open instead of __open
	and __open64.  This fixes a portability bug on HP-UX 11.11i
	reported by Simon Wing-Tang in
	<http://lists.gnu.org/archive/html/bug-coreutils/2006-05/msg00114.html>.

2006-05-23  Paul Eggert  <eggert@cs.ucla.edu>

	* filemode.c: Don't include <string.h>; this include was
	inadvertently put into the previous patch.  Problem noted
	by Jim Meyering.

2006-05-22  Paul Eggert  <eggert@cs.ucla.edu>

	* filemode.c (setst): Remove.
	(strmode): Rewrite to avoid setst.  This makes the code shorter,
	(arguably) clearer, and the generated code is a bit smaller on my
	Debian GNU/Linux stable x86 host.

	Import from gnulib.
	* verify.h: Document the internals better.  Most of this change
	was written by Bruno Haible.

2006-05-21  Jim Meyering  <jim@meyering.net>

	* fts.c (fts_open): Fail with EINVAL if a caller violates this rule:
	Either FTS_LOGICAL or FTS_PHYSICAL must be provided to the
	fts_open() function.

2006-05-19  Paul Eggert  <eggert@cs.ucla.edu>

	* nanosleep.c [HAVE_SYS_SELECT_H]: Include <sys/select.h>.
	Use the usual Autoconf way to include <time.h> and/or sys/time.h.
	(my_usleep): Don't mishandle maximum value.

2006-05-15  Jim Meyering  <jim@meyering.net>

	Avoid the expense of an fstat, when possible.
	* fts.c (O_NOFOLLOW, STREQ): Define.
	(diropen_fd): Remove function.  Merge it into sole caller...
	(diropen): ...here.  Use O_NOFOLLOW when appropriate.
	(fts_safe_changedir): Call fstat for dev/inode check, only if the
	previous open/openat call may have opened the wrong directory.

2006-05-13  Jim Meyering  <jim@meyering.net>

	* xfts.c (xfts_open): Always use FTS_CWDFD.

	Restore the parts of fts that were removed on 2006-01-17, so that
	it's easier for legacy applications designed for the version
	of fts in glibc or BSD to convert to this more robust version.
	Add a new mode, FTS_CWDFD, by which to enable the improved
	(openat- based -- aka no-chdir) semantics.
	* fts_.h (FTS_CWDFD): Define.  Callers must use this fts_open
	option to enable the more robust behavior.
	(FTS_OPTIONMASK): Widen accordingly.
	* fts.c: Restore removed code, reverting the default behavior.

2006-05-11  Jim Meyering  <jim@meyering.net>

	* sha1.c (sha1_buffer): Correct comment: s/MD5/SHA1/.  From James Lemley.

2006-04-25  Paul Eggert  <eggert@cs.ucla.edu>

	* getdate.y (get_date): When adding relative date, start with the
	initial time, not with the result of the first mktime call.

2006-04-17  Paul Eggert  <eggert@cs.ucla.edu>

	* filemode.c: Include "filemode.h" first, to test the interface.
	Assume that filemode.h includes sys/types.h and sys/stat.h.
	(HAVE_ST_DM_MODE): New macro, moved here from ls.c.
	(ftypelet): Reorder to put common cases first, for efficiency.
	Add 'P', 'w'.  Remove 'M', since it's now the caller's responsibility
	to do 'M'.
	(strmode): Renamed from mode_string, and now stores 12 bytes instead
	of 10, for compatibility with FreeBSD.  All callers changed.
	(filemodestring): Now stores 12 bytes instead of 10, and sets file types
	that can't be deduced solely from st_mode.  First arg is now a const
	pointer.
	* filemode.h (HAVE_DECL_STRMODE): Include <string.h> for strmode.
	(strmode): Renamed from mode_string.
	(filemodestring): New decl.
	* stat-macros.h: Don't undef S_ISDOOR, since it's never buggy.
	(S_ISDOOR): Don't bother with S_IFDOOR, since that code is never needed.
	(S_ISPORT, S_ISWHT): New macros, if not already defined.

	* openat.h (openat_needs_fchdir) [ ! defined __OPENAT_PREFIX]:
	Turn this into a macro that always returns false.

2006-04-15  Paul Eggert  <eggert@cs.ucla.edu>

	* utimens.c (futimens): glibc futimesat messes up if /proc
	isn't mounted.  Problem reported by Kir Kolyshkin.

2006-04-14  Jim Meyering  <jim@meyering.net>

	Remove unreachable code and plug leaks in code that handles degenerate
	input and some failure cases.
	* fts.c (fts_build): #if-0-out a block of unused code. Patch from glibc.
	(fts_build): Remove just-#if-0'd code and the code that
	declares and sets cderrno.
	(fts_build): Free `head' before returning NULL, in two places,
	to avoid leaks.  Patch from glibc.
	(fts_open): Don't allocate parent if *argv==NULL.  Patch from glibc.

2006-04-13  Paul Eggert  <eggert@cs.ucla.edu>

	* regcomp.c (init_dfa): Don't use wchar_t or wctype_t if RE_ENABLE_I18N
	is not defined.  Problem reported by Mark D. Baushke via Derek R. Price.
	* regex.h (RE_DUP_MAX): Update comment to match current implementation.

2006-04-12  Paul Eggert  <eggert@cs.ucla.edu>

	* fsusage.c: Don't include <inttypes.h> or <stdint.h>, since
	fsusage.h now does that.  Include fsusage.h first, to test interface.
	Prefer statvfs if it works, since it's blessed by POSIX.  Attempt
	at most one method (the old code could have generated decls that
	didn't conform to C89, not that this was ever exercised).
	* fsusage.h: Include <inttypes.h> and <stdint.h> if they exist.

2006-04-09  Paul Eggert  <eggert@cs.ucla.edu>

	Merge regex changes from libc, removing some of our
	POSIX-conformance changes that were rejected and redoing them in a
	less-intrusive way.

	* regcomp.c (re_compile_internal, init_dfa):
	Length arg is now size_t, not Idx.  All uses changed.
	(peek_token): Forward decl now says internal_function.
	(__re_error_msgid, __re_error_msgid_idx):
	Now static rather than extern with attribute_hidden.
	(re_compile_pattern) [!defined _LIBC]: Use K&R-style defn.
	For some reason libc prefers K&R style defns for external functions.
	(regerror) [!defined _LIBC]: Likewise.
	(re_set_syntax, re_compile_fastmap, regcomp, regfree, re_comp):
	(seek_collating_symbol_entry, lookup_collation_sequence_value):
	(build_range_exp, build_collating_symbol):
	Use K&R-style defn.
	(re_compile_fastmap): Use '\0' to memset, not 0.
	(utf8_sb_map): Make the calculations more obvious.
	(init_dfa, parse_bracket_exp, build_charclass_op):
	Call calloc and cast result, as glibc does.

	(build_range_exp, build_collating_symbol):
	Now internal functions.

	* regex.c [!defined _LIBC]: Allow compiling with C++ compilers.

	* regex.h (__USE_GNU_REGEX): New macro.  Don't depend on
	_REGEX_SOURCE any more; depend on _GNU_SOURCE instead.
	Don't depend on VMS; depend on __VMS instead, for POSIX
	namespace cleanness.
	(regoff_t): Define to ssize_t, not long int.

	Remove the REG_ macros named below.  Instead, make the old names
	(e.g., RE_BACKSLASH_ESCAPE_IN_LISTS) visible only if
	__USE_GNU_REGEX.
	(REG_BACKSLASH_ESCAPE_IN_LISTS):
	(REG_BK_PLUS_QM, REG_CHAR_CLASSES, REG_CONTEXT_INDEP_ANCHORS):

	(RE_BK_PLUS_QM, RE_CHAR_CLASSES, RE_CONTEXT_INDEP_ANCHORS):
	(RE_CONTEXT_INDEP_OPS, RE_CONTEXT_INVALID_OPS):

	(RE_NO_GNU_OPS, RE_DEBUG, RE_INVALID_INTERVAL_ORD):
	(RE_IGNORE_CASE, RE_CARET_ANCHORS_HERE):
	(RE_CONTEXT_INVALID_DUP, RE_NO_SUB):
	Don't bother having these macros be independent of each others'
	values, since they no longer exist in the POSIX name space.

	Rename the following member names back to their old names,
	unless !__USE_GNU_REGEX.  All uses changed back.
	(buffer): Renamed from re_buffer.
	(allocated): Renamed from re_allocated.
	(used): Renamed from re_used.
	(syntax): Renamed from re_syntax.

2006-03-19  Jim Meyering  <jim@meyering.net>

	Work even in a chroot where d_ino values for entries in "/"
	don't match the stat.st_ino values for the same names.
	* getcwd.c (__getcwd): When no d_ino value matches the target inode
	number, iterate through all entries again, using lstat instead.
	Reported by Kenshi Muto in http://bugs.debian.org/355810, and by
	Zouhir Hafidi in https://bugzilla.redhat.com/bugzilla/190656.

	* getcwd.c (__getcwd): Clarify a comment.
	Use memcpy in place of a call to strcpy.

2006-03-16  Paul Eggert  <eggert@cs.ucla.edu>

	* regex.h (regoff_t) [defined _REGEX_LARGE_OFFSETS]:
	Typedef to long int, not to off_, as POSIX will likely change
	in that direction.

2006-03-12  Jim Meyering  <jim@meyering.net>

	* fts-cycle.c (leave_dir): If cycle-check's saved dev-ino pair matches
	that of the current directory (which we're about to chdir ".." out of),
	then save the dev-ino of the parent, instead.

	* same-inode.h (SAME_INODE): New file/macro.
	* chdir-safer.c (SAME_INODE): Remove definition.
	Include "same-inode.h", instead.
	* same.c: Likewise.
	* cycle-check.h: Include "same-inode.h".
	(CYCLE_CHECK_REFLECT_CHDIR_UP): Define.
	* cycle-check.c (SAME_INODE): Remove definition.
	* root-dev-ino.h: Include "same-inode.h".

2006-03-12  Paul Eggert  <eggert@cs.ucla.edu>

	* Makefile.am (libcoreutils_a_SOURCES): Remove time_r.c, time_r.h,
	as this is now done in m4.
	* time_r.h (asctime_r, ctime_r): Remove.  These functions can
	overrun buffers and shouldn't be used (much as gets shouldn't be
	used).
	* time_r.c (asctime_r, ctime_r): Likewise.

2006-02-17  Simon Josefsson  <jas@extundo.com>

	* base64.h, base64.c: New files.

2006-02-20  Paul Eggert  <eggert@cs.ucla.edu>

	* getcwd.c (AT_FDCWD): Work around a bug in Solaris 9 and 10, where
	AT_FDCWD exceeds INT_MAX.
	* openat.h (AT_FDCWD): Likewise.

2006-02-17  Jim Meyering  <jim@meyering.net>

	* openat.c: Include lstat.h, so that uses of lstat are converted
	to uses of rpl_lstat, e.g., on Solaris 9.  Otherwise, programs like
	du (which now uses the openat-enabled fts and hence fstatat) would
	mistakenly fail to dereference a symlink-to-directory specified
	with a trailing slash.

2006-02-14  Paul Eggert  <eggert@cs.ucla.edu>

	* vasnprintf.c (VASNPRINTF): Rewrite the computation so that we
	need not use xsum.

2006-02-14  Bruno Haible  <bruno@clisp.org>

	Sync from gnulib.

	* vasnprintf.c (VASNPRINTF): In the computation of the size of the
	temporary buffer for sprintf, take into account the precision also
	for 'd', 'i', 'u', 'o', 'x', 'X'.

2006-02-14  Simon Josefsson  <jas@extundo.com>

	Sync from gnulib.

	* getaddrinfo.h: Define EAI_ADDRFAMILY and EAI_SYSTEM if not set,
	for mingw32.

	* gai_strerror.c, getaddrinfo.h: Protect netdb.h #include (for
	mingw32).

2006-02-07  Paul Eggert  <eggert@cs.ucla.edu>

	* closeout.c (close_stdout): Don't assume 'bool' converts nonzero
	ints to 0 or 1, as this isn't true for the stdbool.h substitute.

2006-02-02  Jim Meyering  <jim@meyering.net>

	Eliminate the unwelcome (albeit unlikely) possibility of xmalloc
	failure on deficient systems, and simplify gnulib lgpl dependencies.
	* lstat.c (rpl_lstat): Rewrite to use stat() in place of the
	xmalloc/lstat combination.  Based on a patch from Bruno Haible.

2006-01-27  Paul Eggert  <eggert@cs.ucla.edu>

	* fnmatch.c (L_): Renamed from L, to work around a bug in
	Mac OS X 10.3.9 with GCC 3 reported by Claudio Fontana in
	<http://lists.gnu.org/archive/html/bug-gnulib/2006-01/msg00074.html>.
	All uses changed.

2006-01-26  Paul Eggert  <eggert@cs.ucla.edu>

	* stdbool_.h: Sync from gnulib.
	Use signed char with all non-GCC compilers.

2006-01-25  Paul Eggert  <eggert@cs.ucla.edu>

	* stdbool_.h: Merge from gnulib; we still don't quite match exactly,
	but we're getting closer.
	(true, false) [defined __BEOS__]: undef, as before.
	(_Bool) [!@HAVE__BOOL@ && defined __GNUC__]: Use an enum
	rather than a #define.

2006-01-25  Jim Meyering  <jim@meyering.net>

	* fileblocks.c: Remove useless parentheses in cpp directive.
	* readutmp.h: Likewise.

2006-01-23  Paul Eggert  <eggert@cs.ucla.edu>

	Work around porting bugs reported by Dieter in
	<http://lists.gnu.org/archive/html/bug-bison/2006-01/msg00049.html>.
	* getopt.c (_NOPROTO): Remove; no longer needed.
	Include <stdlib.h> and <unistd.h> in all environments; it's safe now.
	Include "getopt.h" first, to check interface.
	(getenv): Declare only if defined HAVE_DECL_GETENV &&
	!HAVE_DECL_GETENV.
	* strndup.c [!_LIBC]: Include "strndup.h" to get prototype.
	(__strndup): Revert to K&R-style function dfns, the glibc style.
	* strnlen.c: Don't claim it's taken from glibc; it's not.
	(strnlen, __strnlen): Remove #defines and #undefs; not needed.
	Include strnlen.h first, to get prototype properly.
	(strnlen): Renamed from __strnlen.
	Remove weak alias.

2006-01-23  Ulrich Drepper  <drepper@redhat.com>

	These changes imported from libc.
	* getopt.c: Use __fxprintf instead of inline stream orientation
	test and two separate function calls.
	* strndup.c (__strndup): Add libc_hidden_def.

2006-01-23  Jim Meyering  <jim@meyering.net>

	* xalloc-die.c: Remove unused definition of N_.

2006-01-22  Paul Eggert  <eggert@cs.ucla.edu>

	* quotearg.c (quotearg_buffer_restyled): Add "default: break;"
	to pacify gcc -Wswitch-default.

2006-01-17  Jim Meyering  <jim@meyering.net>

	Rewrite fts.c not to change the current working directory,
	by using openat, fstatat, fdopendir, etc..

	* fts.c [! _LIBC]: Include "openat.h" and "unistd--.h".
	(HAVE_OPENAT_SUPPORT): Define.
	[_LIBC] (fchdir): Don't undef or define; no longer used.
	(FCHDIR): Define in terms of cwd_advance_fd rather than fchdir.
	Now, this `function' always succeeds, and consumes its file descriptor
	parameter -- so callers must not close such FDs.  Update callers.
	(diropen_fd, opendirat, cwd_advance_fd): New functions.
	(diropen): Add parameter, SP.  Adjust all callers.
	Implement using diropen_fd, rather than open.
	(fts_open): Initialize new member, fts_cwd_fd.
	Remove fts_rft-setting code.
	(fts_close): Close fts_cwd_fd, if necessary.
	(__opendir2): Define in terms of opendir or opendirat,
	depending on whether the FST_NOCHDIR flag is set.
	(fts_build): Since fts_safe_changedir consumes its FD, and since
	this code must do `closedir(dirp)', dup the dirfd(dirp) argument,
	and close the dup'd file descriptor upon failure.
	(fts_stat): Use fstatat(...AT_SYMLINK_NOFOLLOW) in place of lstat.
	(fts_safe_changedir): Tweak semantics to reflect that this function
	now calls cwd_advance_fd and hence consumes its FD argument.
	* fts_.h [struct FTS] (fts_cwd_fd): New member.
	[struct FTS] (fts_rft): Remove now-unused member.
	[struct FTS] (fts_cycle.state): Improve comment.

	* openat.c (openat_needs_fchdir): New function.
	* openat.h (openat_needs_fchdir): Declare it.

2006-01-12  Jim Meyering  <jim@meyering.net>

	* stdint_.h: Remove useless parentheses in cpp directives, so that
	this file passes coreutils' `make syntax-check' tests.

2006-01-11  Paul Eggert  <eggert@cs.ucla.edu>

	* .cvsignore: Add stdint.h.
	* Makefile.am (BUILT_SOURCES, EXTRA_DIST, stdint.h, MOSTLYCLEANFILES):
	Add gnulib snippet.
	* md5.c: Fix commentary typos.
	(alignof, UNALIGNED_P): No need for a GCC-specific version.
	* md5.h (__attribute__): Remove; unused.
	* sha1.c, sha256.c, sha256.c: Fix commentary to match md5 better.
	* sha1.h (struct sha1_ctx): Use a word buffer, not a byte buffer,
	so that we don't need to worry about alignment.  All uses changed.
	This merges the 2005-10-28 md5 change into sha1.
	* sha256.h (struct sha256_ctx): Likewise.
	* sha512.h (struct sha512_ctx): Likewise.
	* sha256.h: Include stdint.h rather than md5.h.
	* sha512.h: Include stdint.h uniformly, since we now have the
	stdint module.
	* stdint_.h: New file, from gnulib.

2006-01-11  Jim Meyering  <jim@meyering.net>

	* fts.c (fts_stat): When following a symlink-to-directory,
	don't necessarily interpret stat-fails+lstat-succeeds as indicating
	a dangling symlink.  That can also happen at least for ELOOP.
	The fix: return FTS_SLNONE only when the stat errno is ENOENT.
	FYI, this bug predates the inclusion of fts.c in coreutils.

2006-01-11  Jim Meyering  <jim@meyering.net>

	* fts.c [!_LIBC]: Include "fcntl--.h", to map open to open_safer.
	(fts_open): Put new (2006-01-04) maxarglen declaration and uses
	in their own block, so pre-c99 compilers don't object.

	* openat.c (fchownat): New function.
	* openat.h (fchmodat, fchownat): Declare.
	(chmodat, lchmodat): Define convenience functions.
	(chownat, lchownat): Likewise.
	* fchmodat.c (fchmodat): New file and function.

	* md5.c (OP): Remove useless space-before-TAB.

2006-01-10  Paul Eggert  <eggert@cs.ucla.edu>

	* localcharset.c, md5.c, md5.h, savedir.c, savedir.h, sha1.c, sha1.h
	* strcasecmp.c, strncasecmp.c, verify.h, regex_internal.h:
	Sync from gnulib.
	* sha256.c, sha256.h, sha512.c, sha512.h:
	Replace all instances of md5_uint32_t with uint32_t, to accommodate
	gnulib change.

2006-01-10  Jim Meyering  <jim@meyering.net>

	Avoid the double-free (first in fts_read, second in fts_close) that
	would occur when an `active' directory is made inaccessible (e.g.,
	via chmod a-x) during a traversal.
	* fts.c (fts_read): After a failed fchdir, update sp->fts_cur
	before returning.  Reproduce this failure by
	mkdir -p a/b; cd a; chmod a-x . b
	Reported by Stavros Passas.

2006-01-06  Jim Meyering  <jim@meyering.net>

	* version-etc.c (COPYRIGHT_YEAR): Update to 2006.

2006-01-04  Paul Eggert  <eggert@cs.ucla.edu>

	* strftime.c (tzname): Don't declare if it is already #defined.
	Problem reported for Mingw by Mark Junker.

2006-01-04  Jim Meyering  <jim@meyering.net>

	Merge from glibc.
	* fts.c (fts_open): Avoid function call in MAX macro use.

2006-01-03  Paul Eggert  <eggert@cs.ucla.edu>

	* xtime.h (xtime_make, xtime_nonnegative_nsec, xtime_nsec): Use
	long int, not int, for nanosecond counts, so that people who are
	used to POSIX struct timespec won't be surprised.  Reported by Jim
	Meyering.

2006-01-01  Paul Eggert  <eggert@cs.ucla.edu>

	* chmod-safer.c, chmod-safer.h: Remove.
	* lchmod.h: New file.
	* mkdir-p.c: Include lchmod.h, lchown.h.
	(make_dir_parents): Use lchown rather than chown, and
	lchmod rather than chmod.

2005-12-26  Paul Eggert  <eggert@cs.ucla.edu>

	* chdir-long.c (cdb_free): Don't bother trying to open directory
	for write access: POSIX says that must fail.
	* chdir-safer.c (chdir_no_follow): Likewise.
	* fts.c (diropen): Likewise.
	* save-cwd.c (save_cwd): Likewise.
	* chdir-long.c (cdb_free): Open with O_NOCTTY | O_NONBLOCK as
	well, for minor improvements on hosts that lack O_DIRECTORY.
	* chmod-safer.c (defined_S_IFMT): New macro.
	Include stat-macros.h.
	Include stdlib.h, for abort().
	Don't include stdio.h or assert.h; no longer needed.
	(same_file_type): Don't assume S_IFMT is defined, as POSIX
	does not require this.  Don't assume S_IFCHR and S_IFBLK have
	their usual sort of bit pattern.
	(fchmod_new): Open with O_NOCTTY for as well, for minor
	improvement on hosts where that matters.  Don't bother to assert,
	since the caller (in this source file) checks the same thing.
	Discard any errno from a close failure, for consistency with other
	code.
	* chown.c (rpl_chown) [CHOWN_MODIFIES_SYMLINK]:
	Don't try O_WRONLY unless O_RDONLY failed wth EACCES.
	Fall back on chown if open failed with EACCES.

2005-12-26  Jim Meyering  <jim@meyering.net>

	* chdir-safer.c (chdir_no_follow): Move declaration of local,
	sb2, `down' into the scope where it is used.
	Note that on some systems this function also fails when DIR
	is a writable-yet-unreadable directory.

2005-12-25  Paul Eggert  <eggert@cs.ucla.edu>

	* chdir-safer.h (FCHMOD_SAFER_H): Remove: it was misnamed, and
	wasn't needed anyay.
	* chdir-safer.c (chdir_no_follow): Don't include stdio.h, assert.h,
	fcntl--.h; not needed.
	(O_DIRECTORY): Define if not already defined.
	(chdir_no_follow): Revamp describing comment to match code more
	closely.  Redo use of internal vars to avoid lint complaints.
	Work even if directory is writeable but not readable.
	Open with O_DIRECTORY | O_NOCTTY, for benefit of hosts that
	don't have O_NOFOLLOW.  Use O_NONBLOCK (POSIX spelling) rather
	than O_NDELAY.  Don't bother invoking fstat if open does not
	dereference symlink, since the result isn't used then.
	Don't assume file descriptor is positive; it might be zero
	now that we no longer include fcntl--.h (we don't need fcntl--.h
	since we immediately close the descriptor).

2005-12-25  Jim Meyering  <jim@meyering.net>

	* chdir-safer.c (chdir_no_follow): Remove unnecessary
	test of S_ISDIR (sb_init.st_mode).

2005-12-23  Jim Meyering  <jim@meyering.net>

	* mkdir-p.c (make_dir_parents): Use chdir_no_follow only
	if we've just created the directory.

	* chdir-safer.c (chdir_no_follow): Rewrite to use fchdir even
	when O_NOFOLLOW is not defined.  Suggested by James Youngman.

	* chmod-safer.c (O_NOFOLLOW): Define, if necessary.
	* chdir-safer.c (O_NOFOLLOW): Likewise.
	Reported by Eric Blake.

2005-12-22  Jim Meyering  <jim@meyering.net>

	* openat.c: Include "fcntl--.h" and "unistd--.h", to map open
	and dup to open_safer and dup_safer, respectively.
	(openat_permissive): Fix typo in comment.

2005-12-21  Jim Meyering  <jim@meyering.net>

	Like chdir(2), but safer, if possible.
	* chdir-safer.c, chdir-safer.h: New files.

2005-12-20  Jim Meyering  <jim@meyering.net>

	* mkdir-p.c (RW_USR): Remove definition.
	(make_dir_parents): Use S_IRWXU, now that read access is also required.

	Avoid a race condition, on systems where open honors O_NOFOLLOW.
	* mkdir-p.c (make_dir_parents): Include chdir-safer.h.
	Use chdir_no_follow in place of chdir.

	* mkdir-p.c (make_dir_parents): Remove unnecessary casts of alloca,
	since now it's guaranteed to be (void *).

	* chmod-safer.c (fchmod_new): Don't try to close fd if it's < 0.

2005-12-19  Jim Meyering  <jim@meyering.net>

	* chmod-safer.c, chmod-safer.h: New files.

2005-12-05  Andreas Gruenbacher  <agruen@suse.de>

	Add POSIX ACL support
	* acl.h (copy_acl, set_acl): Add declarations.
	* acl.c (acl_entries): Add fallback implementation for POSIX ACL
	systems other than Linux.
	(chmod_or_fchmod): New function: use fchmod when possible,
	and chmod otherwise.
	(file_has_acl): Add a POSIX ACL implementation, with a
	Linux-specific subcase.
	(copy_acl): Add: copy an acl and S_ISUID, S_ISGID, and
	S_ISVTX from one file to another.  Fall back to fchmod/chmod when
	acls are unsupported.
	(set_acl): Add: set a file's acl and S_ISUID, S_ISGID, and
	S_ISVTX to a defined value.  Fall back to fchmod/chmod when acls
	are unsupported.

2005-12-16  Paul Eggert  <eggert@cs.ucla.edu>

	* openat.c: Don't include <stdlib.h>, <unistd.h>, <fcntl.h>,
	"gettext.h"; either no longer needed or are guaranteed by openat.h.
	(_): Remove; no longer needed.
	(openat): Renamed from rpl_openat; no need for rpl_openat
	since openat.h renames openat for us.
	Replace most of the body with a call to openat_permissive,
	to avoid duplicate code.
	Port to (probably hypothetical) environments were mode_t is
	wider than int.
	(openat_permissive): Require mode arg, so that we can check
	types better.  Put it just after flags.  Change cwd failure
	indicator from pointer-to-bool to pointer-to-errno-value.
	All callers changed.
	Invoke openat_save_fail and/or openat_restore_fail if
	cwd_errno is null, so that openat can call us.
	(openat_permissive, fdopendir, fstatat, unlinkat):
	Simplify errno handling to avoid some duplicate code,
	as it's OK to set errno on success.
	* openat.h: Revamp code so that function macros depend on
	__OPENAT_PREFIX only, not also on AT_FDCWD.
	(openat_ro): Remove.  Caller changed to use openat_permissive.
	(openat_permissive): Now a macro, if not a function.
	(openat_restore_fail, openat_save_fail): Now always functions,
	since mkdirat needs them even if __OPENAT_PREFIX is defined.

2005-12-14  Jim Meyering  <jim@meyering.net>

	* Makefile.am (libcoreutils_a_SOURCES): Remove fprintftime.c
	and fprintftime.h.  Now they're pulled in via the .m4 file.

2005-12-13  Paul Eggert  <eggert@cs.ucla.edu>

	* Makefile.am (stdbool.h): Resurrect the 'sed' that goes along
	with '#if !@HAVE_BOOL@".
	* stdbool_.h (_Bool): Resurrect the "#if !@HAVE__BOOL@" check, to
	work around compilers that have a (possibly-broken) _Bool but lack
	a working <stdbool.h>.

2005-12-07  Paul Eggert  <eggert@cs.ucla.edu>

	* stat-time.h (STATE_TIMESPEC, STAT_TIMESPEC_NS): Add check for
	TYPEOF_STRUCT_STAT_ST_ATIM_IS_STRUCT_TIMESPEC, to fix IRIX 5.3
	porting problem reported by Georg Schwarz in
	<http://lists.gnu.org/archive/html/bug-coreutils/2005-12/msg00083.html>.

2005-12-04  Jim Meyering  <jim@meyering.net>

	* openat-priv.h (EXPECTED_ERRNO): Add ENOSYS, for Solaris 8.
	Paul Eggert reported that unlink/rmdir vs. e.g., /proc/self/fd/N/FILE
	fails with ENOSYS.  This makes openat revert to using save-cwd.c
	functions in that case.

2005-12-01  Paul Eggert  <eggert@cs.ucla.edu>

	Sync from gnulib.

	* exclude.c: Include verify.h.
	(verify): Remove.  All callers changed to use verify.h's version.
	* strtoimax.c: Likewise.
	* utimecmp.c: Likewis.e

	* obstack.c [defined _LIBC && defined USE_IN_LIBIO]: Don't
	include <wchar.h>; no longer needed.

2005-12-01  Jim Meyering  <jim@meyering.net>

	Sync from gnulib.

	* intprops.h (signed_type_or_expr__): Define.
	(INT_STRLEN_BOUND) [__GNUC__]: Use a slightly tighter bound
	for unsigned types.

2005-12-01  Jakub Jelinek  <jakub@redhat.com>
	and  Ulrich Drepper  <drepper@redhat.com>

	Import from libc via gnulib.
	* obstack.c (print_and_abort) [defined _LIBC]: Use __fxprintf
	instead of inline stream orientation test and two separate
	function calls.  Pay no attention to USE_IN_LIBIO.

2005-12-01  Roland McGrath  <roland@redhat.com>

	Import from libc via gnulib.  [BZ #1331]
	* obstack.h [!__STDC__] (obstack_int_grow_fast): Fix misnamed
	macro argument.
	Reported by Matej Vela <vela@debian.org>.

2005-11-30  Jim Meyering  <jim@meyering.net>

	* openat-priv.h: New file, defining macros used by mkdirat.c
	and openat.c.
	* mkdirat.c: Include openat-priv.h.
	Remove definitions of macros defined therein.
	* openat.c: Likewise.

	* mkdirat.c (mkdirat): New file and function.
	* openat.h (mkdirat): Declare.

2005-11-25  Paul Eggert  <eggert@cs.ucla.edu>

	* mountlist.c (ME_DUMMY): "none" and "proc" file systems are dummies
	too.  Problem with "none" reported by Bob Proulx.  Problem with
	"proc" reported by n0dalus.

	* mountlist.c: Include <limits.h>.
	(dev_from_mount_options)
	[defined MOUNTED_GETMNTENT1 || defined MOUNTED_GETMNTENT2]:
	New function.  It no longer assumes "dev=" has the System V meaning
	on Linux (since it doesn't).  It also parses "dev=" more carefully.
	(read_file_system_list)
	[defined MOUNTED_GETMNTENT1 || defined MOUNTED_GETMNTENT2]: Use it.
	MOUNTED_GETMNTENT2 is new here; the code didn't used to look for
	dev= in that case.

	* Makefile.am (stdbool.h): Just copy stdbool_.h; no need to sed
	any more.

	* stdbool_.h: Simplify greatly, under the assumption that these
	days most people use C99-compatible compilers to debug, so it's
	not worth worrying about catering to older compilers for that.
	This works around some porting problems with HP-UX compilers.
	(false, true) [defined __BEOS__]: Don't #undef; no longer needed.
	(_Bool): typedef to bool if C++ or BeOS, and #define to signed char
	otherwise.

	* gettime.c (gettime) [!defined OK_TO_USE_1S_CLOCK]:
	Report an error at compile-time if only a 1-second nominal clock
	resolution is found.

2005-11-23  Paul Eggert  <eggert@cs.ucla.edu>

	* Makefile.am (libcoreutils_a_SOURCES): Add buffer-lcm.c, buffer-lcm.h.
	* buffer-lcm.c, buffer-lcm.h: New files, from diffutils.

2005-11-23  Jim Meyering  <jim@meyering.net>

	* openat.c (fdopendir): Don't change errno when returning non-NULL.

2005-11-22  Jim Meyering  <jim@meyering.net>

	* openat.h (openat_permissive): Declare.
	(openat_ro): Define.

	* openat.c (EXPECTED_ERRNO): New macro.
	(openat_permissive): New function -- used in remove.c rewrite.
	(all functions): Set errno just before returning, only if there
	was an actual failure.
	Use EXPECTED_ERRNO rather than comparing against only ENOTDIR.

2005-11-20  Jim Meyering  <jim@meyering.net>

	* euidaccess-stat.c: New file, mostly from euidaccess.c.
	* euidaccess-stat.h: New file.

2005-11-15  Paul Eggert  <eggert@cs.ucla.edu>

	* xstrtod.c: Don't bother with #pragma STDC FENV_ACCESS ON, as
	coreutils no longer futzes with rounding modes.

2005-11-08  Eric Blake  <ebb9@byu.net>

	* getaddrinfo.h: Use #if !, not #ifndef, for AC_CHECK_DECLS.

2005-11-13  Jim Meyering  <jim@meyering.net>

	* mkstemp-safer.c: Include <config.h>, required for possible
	replacement of mkstemp.

2005-11-12  Jim Meyering  <jim@meyering.net>

	Emulate openat-family functions using Linux's procfs, if possible.
	Idea and some code based on Ulrich Drepper's glibc changes.

	* openat.c: (BUILD_PROC_NAME): New macro.
	Include <stdio.h>, <string.h>, "alloca.h" and "intprops.h".
	(rpl_openat): Emulate by trying to open /proc/self/fd/%d/%s,
	before falling back on save_cwd and restore_cwd.
	(fdopendir, fstatat, unlinkat): Likewise.

2005-11-11  Jim Meyering  <jim@meyering.net>

	* openat.c (fstatat, unlinkat): Perform the syscall directly,
	skipping the save_cwd...restore_cwd overhead, if FILE is absolute.

2005-11-10  Paul Eggert  <eggert@cs.ucla.edu>

	* gethrxtime.c: Include "timespec.h" rather than the sys/time / time
	business.
	(gethrxtime) [! (HAVE_NANOUPTIME
	|| (defined CLOCK_MONOTONIC && HAVE_CLOCK_GETTIME)
	|| HAVE_MICROUPTIME)]: Fall back on gettime rather than rolling
	our own approximation.

2005-11-01  Paul Eggert  <eggert@cs.ucla.edu>

	* posixtm.h (PDS_PRE_2000): New macro.
	* posixtm.c (year): Arg is now syntax_bits rather than allow_century.
	All usages changed.  Reject dates outside the range 1969-1999 if
	PDS_PRE_2000 is used.

2005-10-30  Paul Eggert  <eggert@cs.ucla.edu>

	Fix porting problems reported by Theodoros V. Kalamatianos.
	* fd-reopen.c [defined HAVE_CONFIG_H]: Include <config.h>,
	so that large files can be opened.
	* utimens.c (futimens) [HAVE_WORKING_UTIMES && HAVE_FUTIMES]:
	Don't assume that futimes failing means we must fail.

2005-10-29  Paul Eggert  <eggert@cs.ucla.edu>

	* getcwd.c (__getcwd): Don't assume that system calls after readdir
	leave errno alone.  Problem reported by Dmitry V. Levin.

2005-10-28  Paul Eggert  <eggert@cs.ucla.edu>

	* savedir.c (savedir): Don't assume that xrealloc etc. leave
	errno alone.  Problem reported by Frederic Jolliton.

2005-10-24  Jim Meyering  <jim@meyering.net>

	* mkdir-p.c (make_dir_parents): Like the code above, don't rely
	on mkdir failing with a particular errno value (EEXIST).
	Based on a patch by Dmitry V. Levin.

	* mkdir-p.c (make_dir_parents): Make the preceding fix a little
	more robust, e.g., when the final component is created as a non-
	directory by another process just before `mkdir -p's final mkdir.

	A command like `mkdir -p nonexistent/.' would create the
	directory but exit nonzero with a diagnostic.  This could also be
	triggered with a non-`.' component, e.g., in a race with another
	process running the same `mkdir -p nonexistent/sub' command.

	* mkdir-p.c (make_dir_parents): Handle the case of an
	existing final component.
	Reported by Matthias Andree here:
	http://savannah.gnu.org/bugs/?func=detailitem&item_id=14848

2005-10-23  Jim Meyering  <jim@meyering.net>

	* sha512.h: Remove no-longer-relevant comment.

2005-08-27  David Madore  <david.madore@ens.fr>

	* sha256.h, sha256.c, sha512.h, sha512.c: New files - sha-2
	implementation.

2005-10-20  Jim Meyering  <jim@meyering.net>

	* modechange.c (mode_compile): Reject an invalid mode string
	that starts with an octal digit.  From Andreas Gruenbacher.

2005-10-13  Paul Eggert  <eggert@cs.ucla.edu>

	* mkdir-p.c (make_dir_parents): Don't report an error if an
	intermediate directory is in a read-only file system.  Problem
	reported by Eric Blake.

2005-10-08  Jim Meyering  <jim@meyering.net>

	* openat.c (rpl_openat): Use the promoted type (int), not mode_t,
	as second argument to va_arg.  Otherwise, some versions of gcc
	warn that `if this code is reached, the program will abort'.

	Update from gnulib.
	* getdelim.c: (SIZE_MAX): New macro, if not already defined.

2005-10-05  Jim Meyering  <jim@meyering.net>

	* Makefile.am (libcoreutils_a_DEPENDENCIES): Remove definition.
	Once it's gone, automake generates an equivalent one.
	Suggestion from Stepan Kasal.

	* getaddrinfo.h: Merge from gnulib.

2005-10-04  Jim Meyering  <jim@meyering.net>

	Merge from gnulib.
	* getaddrinfo.h: Include sys/types.h before other headers.

2005-10-02  Paul Eggert  <eggert@cs.ucla.edu>

	* getdelim.c: Import from gnulib (to fix unused var warnings) then
	apply the following fixes:
	Include getdelim.h first.  Include <limits.h>.
	(SSIZE_MAX): New macro, if not already defined.
	(getdelim): Fix buffer overrun on 64-bit hosts with lines longer
	than 2 GiB.

2005-10-01  Simon Josefsson  <jas@extundo.com>

	* getaddrinfo.h: Protect #include's of sys/socket.h and netdb.h.
	Only define struct addrinfo if !HAVE_STRUCT_ADDRINFO.  Protect
	AI_* and EAI_* definitions.  Protect function declarations.

2005-09-29  Paul Eggert  <eggert@cs.ucla.edu>

	* openat.c (fdopendir): Do not define if HAVE_FDOPENDIR.
	Remove AT_FDCWD test.
	Do not consume the fd unless successful.
	* openat.h (fdopendir): Do not define if HAVE_FDOPENDIR.

2005-09-29  Paul Eggert  <eggert@cs.ucla.edu>

	* xtime.h (XTIME_PRECISION): Now of type int, not long long int,
	so that the code works even with ancient cpp.  Portability problem
	with GCC 2.7.2.1 reported by Thomas M.Ott.

	* settime.c (settime): Fix { typo in previous patch.  Also, don't
	bother returning ENOSYS if settimeofday or stime fails; just let
	them return whatever errno they want to return.

2005-09-29  Jim Meyering  <jim@meyering.net>

	* settime.c (settime): Move the HAVE_STIME block `up' into an #elif
	block, so that we don't even try to compile it if settimeofday is
	available.  This works around a compilation failure on OSF1 V5.1,
	due to stime requiring a `long int*' while tv_sec is `int'.

2005-09-27  Jim Meyering  <jim@meyering.net>

	* fprintftime.c [HAVE_CONFIG_H]: Include <config.h> conditionally,
	to be consistent with gnulib.
	* getcwd.c: Change #ifdef<TAB>HAVE_CONFIG_H to #ifdef HAVE_CONFIG_H.
	* fts-cycle.c [HAVE_CONFIG_H]: Include <config.h>.
	* strnumcmp.c [HAVE_CONFIG_H]: Include <config.h> here, now that
	strnumcmp-in.h no longer includes it.

2005-09-26  Paul Eggert  <eggert@cs.ucla.edu>

	* utimens.c: Include unistd.h, for dup2.
	(futimens): Fix typo: HAVE_FUTIMESAT was misspelled in an #if.
	(futimens) [! HAVE_FUTIMESAT]: If !file, set errno before returning -1.

2005-09-25  Jim Meyering  <jim@meyering.net>

	* strnumcmp-in.h: Protect against multiple inclusion.

2005-09-24  Paul Eggert  <eggert@cs.ucla.edu>

	* utimens.c (ENOSYS): Define if not already defined.
	(futimens): Support having a null PATH if the file descriptor
	is nonnegative.

	* Makefile.am (libcoreutils_a_SOURCES): Remove mbchar.c, since
	it doesn't build in OpenBSD 3.4.  See
	<http://lists.gnu.org/archive/html/bug-gnulib/2005-09/msg00242.html>.

	* regex_internal.h (__GNUC_PREREQ, always_inline, inline, pure):
	Remove.
	(__attribute): Define to empty unless GCC 3.1 or later.
	This works around a core dump on OpenBSD 3.4, which has GCC
	2.95.3, which dumps core when given __attribute__(()).  It also
	simplifies other tests, since we really don't want to bother with
	worrying about which ancient version of GCC supported what.
	Original problem reported by Yoann Vandoorselaere, with part of
	the fix suggested by Derek Price.

2005-09-24  Jim Meyering  <jim@meyering.net>

	* openat-die.c, root-dev-ino.c, setenv.c, stdopen.c:
	* tsearch.c, unsetenv.c, xfts.c: Use `#ifdef HAVE_CONFIG_H',
	not `#if HAVE_CONFIG_H', for consistency with gnulib.

	* strintcmp.c: Include <config.h> here, ...
	* strnumcmp-in.h: ..., not here.

	Sync from gnulib.

	* verify.h (verify_type__): Use `unsigned int' as the bitfield type
	so we can once again use a positive bitfield width of 1 -- now we
	don't have to explain why we were using a bitfield width of 2.

2005-09-23  Paul Eggert  <eggert@cs.ucla.edu>

	* utimens.c (futimens): Use futimesat if available.
	Prefer it to futimes since it doesn't have the futimes bug.

	* verify.h (GL_CONCAT0, GL_CONCAT): Remove.
	(verify): Don't use the __LINE__ trick, as it doesn't work in general.
	Instead, declare a function that returns a pointer to an array,
	and use verify_type__ to declare the size of the array.
	Problem and germ of a solution reported by Bruno Haible.
	(verify_type__): Use 2, not 1, for bitfield size, to avoid
	a warning with Irix 6.5 cc.  Problem reported by Bruno Haible.

2005-09-23  Jim Meyering  <jim@meyering.net>

	* strnumcmp-in.h: Include <config.h>.  Otherwise builds with strict
	C89 (e.g., Sun's /opt/SUNWspro/bin/c89) would fail due to the use
	of `inline'.

2005-09-22  Paul Eggert  <eggert@cs.ucla.edu>

	* getaddrinfo.c [HAVE_NETINET_IN_H]: Include <netinet/in.h>.
	Problem reported by Eric Blake.
	(getaddrinfo): Initialize se so that it's not garbage.
	Redo internal storage allocation so that it doesn't make unportable
	assumptions about alignment.
	Fix a memory leak.

2005-09-21  Paul Eggert  <eggert@cs.ucla.edu>

	Sync from gnulib.

	* Makefile.am (libcoreutils_a_SOURCES): Add getaddrinfo.h,
	mbchar.c, mbchar.h, mbuiter.h, strcase.h, strlen1.c, strnlen1.h,
	strstr.h.

	* argmatch.h (GL_CONCAT): Remove.
	Include "verify.h" instead.
	(ARGMATCH_CONSTRAINT, ARGMATCH_ASSERT): Remove.
	(ARGMATCH_VERIFY): Rewrite in terms of new verify macros.

	* xalloc.h (VERIFY_EXPR, X2NREALLOC, X2REALLOC): Remove.
	The latter two macros are moving to ../src/system.h for now.
	This reverts this file to the gnulib version.

	* xanstrftime.c, xanstrftime.h: Remove; no longer used.

	* .cppi-disable: Add getaddrinfo.h, getdelim.h, mbchar.h,
	mbuiter.h, strcase.h, strnlen.h, strnlen1.h.

	* canon-host.h, gai_strerror.c, getaddrinfo.c, getaddrinfo.h:
	* getdelim.c, getdelim.h, mbchar.c, mbchar.h, mbuiter.h:
	* strcase.h, strnlen.h, strnlen1.c, strnlen1.h, strstr.h:
	New files, from gnulib.

	* __fpending.c, __fpending.h, acl.c, argmatch.c, atexit.c:
	* backupfile.c, basename.c, calloc.c, canonicalize.c:
	* chdir-long.c, chown.c, cloexec.c, closeout.c, creat-safer.c:

	Sync from gnulib.

	* canon-host.c, getline.c, getline.h, getpass.c, strcasecmp.c:
	* strncasecmp.c, strstr.c:
	Nontrivial sync from gnulib.

	* .cvsignore: Sort entries.

	* mkdir-p.c (ENOSYS): Define to EEXIST if not defined.
	(make_dir_parents): Treat ENOSYS like EEXIST.

2005-09-20  Jim Meyering  <jim@meyering.net>

	* openat.c (fdopendir): Be sure to close the supplied
	file descriptor before returning.  This makes our replacement
	implementation a little closer to Solaris's, where fdopendir
	ties the file descriptor to the returned DIR* pointer.

2005-09-19  Jim Meyering  <jim@meyering.net>

	* openat.c (unlinkat): New function.
	* openat.h (unlinkat): Add prototype.

2005-09-16  Paul Eggert  <eggert@cs.ucla.edu>

	Import from gnulib.
	* stat-time.h: New file.
	* timespec.h (ST_TIME_CMP_NS, ST_TIME_CMP, ATIME_CMP, CTIME_CMP):
	(MTIME_CMP, TIMESPEC_NS): Remove.  Now done by stat-time.h,
	in a different way.
	(timespec_cmp): New function.
	* utimecmp.c: Include stat-time.h.
	(SYSCALL_RESOLUTION): Depend on whether various struct stat
	members exist, not on the obsolescent ST_MTIM_NSEC.
	(utimecmp): Use the new stat-time functions rater than TIMESPEC_NS.

	* .cppi-disable: Add stat-time.h.

2005-09-16  Jim Meyering  <jim@meyering.net>

	* strftime.c [FPRINTFTIME] (fprintftime): Provide a new interface:
	size_t fprintftime (FILE *fp, char const *fmt, struct tm const *tm,
			    int utc, int nanoseconds);
	Background:
	date should not have to allocate a megabyte of virtual memory to
	handle a format argument like +%1048575T.  When implemented with
	strftime, it must allocate such a buffer, use strftime to fill it
	in, print it, then free it.
	With fprintftime, it simply prints everything and exits.
	With no need for memory allocation, that's one fewer way to fail.

	* fprintftime.c, fprintftime.h: New files.
	* Makefile.am (libcoreutils_a_SOURCES):
	Add fprintftime.c and fprintftime.h.

2005-09-15  Paul Eggert  <eggert@cs.ucla.edu>

	* strftime.c (my_strftime): Rewrite the previous change slightly,
	to make it a bit faster and (I hope) clearer.

2005-09-14  Jim Meyering  <jim@meyering.net>

	* strftime.c (my_strftime): Parse the colons of %:::z *after* the
	optional field width, not before, so we accept %9:z, not %:9z.
	(my_strftime): Be sure to use L_('x') for literals.

2005-09-13  Paul Eggert  <eggert@cs.ucla.edu>

	Merge md5 from libc, and clean up some sha1 glitches.
	* md5.h (__GNUC_PREREQ, __THROW, __attribute__): New macros.
	(__md5_buffer): Renamed from md5_buffer.  Add a macro undoing this
	if _LIBC is not defined.  Add __THROW.
	(__md5_finish_ctx, __md5_init_ctx, __md5_process_block):
	(__md5_process_bytes, __md5_read_ctx, __md5_stream): Likewise.
	(struct md5_ctx): Mark buffer as being aligned.
	(rol): Remove; all uses changed to CYCLIC.
	* md5.c (CYCLIC): New macro.  All uses of rol changed to use CYCLIC.
	Redo comment to minimize changes from libc.
	* sha1.h (struct sha1_ctx): Mark buffer as being aligned.
	* sha1.c (SWAP): Renamed from NOTSWAP, to avoid a horrible misnaming.
	All uses changed.  Remove the old SWAP.
	Remove obvious comment about BLOCKSIZE.
	(rol): New macro, moved here from md5.h.
	(sha1_process_block): Remove an incoherent FIXME comment.

	* strftime.c (my_strftime): Add support for %:z, %::z, %:::z.
	Fix bug in formats like %2N.

2005-09-13  Jim Meyering  <jim@meyering.net>

	* xalloc.h: Revert unintended change that removed definitions
	of X2REALLOC and X2NREALLOC.

	* backupfile.c: Use ARGMATCH_VERIFY, just in case.

2005-09-09  Paul Eggert  <eggert@cs.ucla.edu>

	* regcomp.c, regex.c, regex.h, regex_internal.c, regex_internal.h:
	* regexec.c: Import from gnulib, to fix some 64-bit bugs.

2005-09-06  Paul Eggert  <eggert@cs.ucla.edu>

	* verify.h (__builtin_constant_p): Remove, undoing previous change.
	(verify_type__): Solve the problem by using a bit-field rather
	than an array.

2005-09-05  Jim Meyering  <jim@meyering.net>

	* verify.h (__builtin_constant_p) [__GNUC__ <= 2]: Define to 1.
	(verify_type__) [verify_error_if_non_const__]: New member/test,
	to help detect when verify or verify_expr is mistakenly passed
	a non-constant argument within a function.

2005-08-31  Jim Meyering  <jim@meyering.net>

	* quotearg.c (quotearg_n_options): Change code to be suboptimal, in
	order to avoid an unsuppressible warning from gcc on 64-bit systems.

	* localcharset.c (get_charset_aliases): Add `void' in parameter list
	to placate gcc's -Wstrict-prototypes.

2005-08-27  Jim Meyering  <jim@meyering.net>

	* md5.c: Use `#error' rather than a string literal to provoke failure.
	* sha1.c: Likewise.

2005-08-25  Jim Meyering  <jim@meyering.net>

	* open-safer.c: Include <config.h>.
	Otherwise, we'd lose LARGEFILE support in any file using
	e.g. "fcntl--.h"

2005-08-24  Jim Meyering  <jim@meyering.net>

	* stdopen.c (stdopen): Revert to iterating over descriptors, but
	rather than using fstat, use fcntl with its F_GETFD flag, which
	is more efficient.  Unlike the 2-syscall dup-close approach,
	this one doesn't apply any unnecessary pressure on the file
	descriptor pool -- thus there is one fewer way to fail.

2005-08-23  Jim Meyering  <jim@meyering.net>

	* regcomp.c, regex.c, regex.h, regex_internal.c: Update from gnulib.
	* regex_internal.h, regexec.c: Likewise.

2005-08-19  Jim Meyering  <jim@meyering.net>

	* stdopen.c (stdopen): Return `bool' so caller can detect failure.

2005-08-17  Jim Meyering  <jim@meyering.net>

	Make the %s format (seconds since the epoch) work for a negative
	number and when used with a zero-padded field width, e.g. %015s.

	* strftime.c (my_strftime): Move the `do_number_sign_and_padding'
	label so that it precedes the code to set `digits'.  Otherwise,
	%0Ns wouldn't work.  Before this change, `date -d @-22 +%05s' would
	print `00-22'.  Now, it prints `-0022', as it should.

2005-08-15  Bruno Haible  <bruno@clisp.org>

	Import from gnulib.
	* regex.h (__restrict_arr): Don't define to __restrict if __cplusplus
	is defined.

2005-08-13  Jim Meyering  <jim@meyering.net>

	* getdate.y (get_date): Undo part of the 2005-04-04 change, so that
	the command "date -d'2005-03-27 +1 day'" succeeds once again, even
	when run in a time zone for which daylight savings time is in effect
	for the starting date.

2005-08-12  Jim Meyering  <jim@meyering.net>

	* regcomp.c (duplicate_node) [lint]: Set *new_idx to -1, to avoid
	warnings (unfounded) in caller that it may be used uninitialized.

	* regex.c (IF_LINT): Define.

	* regex_internal.c (re_string_realloc_buffers): Rename local-shadowed
	variable: s/new_array/offsets/.
	(re_acquire_state) [lint]: Set *err, to avoid warnings in caller.

	* regexec.c (regexec, re_search_stub) [!_LIBC]: Omit declaration
	of unused local, dfa.
	(proceed_next_node): Remove outer declaration and
	unnecessary initialization of local-shadowed `dest_node'.
	Declare it in inner scopes, nearer its uses instead.

	* regex.h (RE_SYNTAX_POSIX_AWK): Remove useless space-before-TAB.

	* fts-cycle.c (setup_dir, enter_dir, leave_dir, free_dir):
	Use the hash-table-based cycle-detection code not just when
	FTS_TIGHT_CYCLE_CHECK if specified, but also with FTS_LOGICAL.
	Reported by James Youngman in
	<http://lists.gnu.org/archive/html/bug-gnulib/2005-08/msg00011.html>.
	* fts_.h: Mention that with FTS_LOGICAL, we use FTS_TIGHT_CYCLE_CHECK.

	* fts.c (fts_cross_check) [FTS_DEBUG]: s/active_dir_ht/fts_cycle.ht/.
	This lets us compile with -DFTS_DEBUG, once again.

2005-08-02  Jim Meyering  <jim@meyering.net>

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

2005-07-21  Paul Eggert  <eggert@cs.ucla.edu>

	* getdate.y (relative_time): New type.
	(RELATIVE_TIME_0): New constant.
	(parser_control): Use relative_time instead of doing it ourselves.
	(%union): Add new relative_time rel member.
	(tYEAR_UNIT, tMONTH_UNIT, tHOUR_UNIT, tMINUTE_UNIT, tSEC_UNIT):
	Now typeless.
	(relunit, relunit_snumber): Now of type rel.
	(zone, rel, relunit, get_date): Adjust to above changes.

2005-07-12  Jim Meyering  <jim@meyering.net>

	* xalloc.h (X2NREALLOC): Define.

2005-07-11  Paul Eggert  <eggert@cs.ucla.edu>

	* verify.h (verify_expr): Use ((verify_type__ (R) *) 0), not
	sizeof (verify_type__ (R)), to pacify C++ compilers.  Problem
	reported by Bruno Haible.

	* version-etc-fsf.c (version_etc_copyright): Parameterize the
	copyright symbol and the year.
	* version-etc.c (COPYRIGHT_YEAR): New constant.
	(version_etc_va): Use parameterized copyright notice.
	Reword to conform to the current GNU coding standards.

2005-07-08  Eric Blake  <ebb9@byu.net>  (tiny change)

	* getloadavg.c (getloadavg) [__CYGWIN__]: Port to cygwin.
	[__linux__]: Allocate a big enough buffer for /proc/loadavg.
	[!LDAV_DONE]: Avoid unused variable warning.

2005-07-08  Eric Blake  <ebb9@byu.net>  (tiny change)
	and  Paul Eggert  <eggert@cs.ucla.edu>

	* regcomp.c (init_dfa, build_range_exp): Store __btowc value
	in wint_t, not wchar_t.  Remove now-unnecessary cast.

2005-07-07  Paul Eggert  <eggert@cs.ucla.edu>

	Switch to Isamu Hasegawa's implementation of regex, which is
	now in gnulib.
	* regcomp.c, regex_internal.c, regex_internal.h, regexec.c:
	New files, from gnulib.
	* regex.h, regex.c: Sync from gnulib.
	* Makefile.am (libcoreutils_a_SOURCES): Remove regex.h; gnulib
	now does this automatically for us.
	* .cppi-disable: Add regcomp.c, regex_internal.c, regex_internal.h.

2005-07-04  Paul Eggert  <eggert@cs.ucla.edu>

	* verify.h (GL_CONCAT0, GL_CONCAT): Define unconditionally; don't
	depend on whether verify_decl is defined.
	(verify): Renamed from verify_decl.  All uses changed.
	Use an extern function decl, as it can't possibly collide with other
	decls.
	(verify_expr): Renamed from verify.  All uses changed.
	(verify_type__): New private macro.
	(verify, verify_expr): Use it.

2005-07-04  Jim Meyering  <jim@meyering.net>

	* verify.h (verify, verify_decl): New file/macros.
	* Makefile.am (libcoreutils_a_SOURCES): Add verify.h here, temporarily.
	Eventually, it'll be pulled in via AC_LIBSOURCES.

	* argmatch.h (verify_dcl): Rename from VERIFY.  Update use.

2005-07-03  Paul Eggert  <eggert@cs.ucla.edu>

	Remove the dependency of the strftime module on the tzset module.
	* strftime.c (my_strftime) [! defined _LIBC && ! HAVE_RUN_TZSET_TEST]:
	Copy the input structure, to work around some of the bug with
	Solaris 2.5.1 and Solaris 2.6.

2005-07-03  Jim Meyering  <jim@meyering.net>

	* posixtm.c (posixtime) [lint]: Initialize *all* of tm0, not just
	the .tm_year member, since otherwise gcc-4.0 would now warn about
	tm_zone, tm_gmtoff, tm_isdst, tm_yday, tm_wday.

2005-07-03  Paul Eggert  <eggert@cs.ucla.edu>

	* Makefile.am (libcoreutils_a_SOURCES): Undo previous change.

	* Makefile.am (libcoreutils_a_SOURCES): Add fcntl--.h, stdio--h,

	* fd-reopen.c: New files.
	* fopen-safer.c: Include stdio-safer.h first, to check interface.
	Don't bother including stdio.h, since stdio-safer.h does.
	* fts.c (fd_safer): Remove decl.
	Include fcntl--.h rather than unistd-safer.h
	(fts_safe_changedir): Don't call fd_safer; no longer needed
	now that we include fcntl--.h.
	* getloadavg.c: Include fcntl--.h rather than fcntl.h.
	Do not include unistd-safer.h.
	(getloadavg): Don't call fd_safer; no longer needed
	now that we include fcntl--.h.
	* getusershell.c: Include stdio--.h rather than stdio.h
	and stdio-safer.h.
	(getusershell): Call fopen, not fopen_safer.
	* save-cwd.c: Include fcntl--.h rather than fcntl.h.
	Do not include unistd-safer.h.
	(save_cwd): Don't call fd_safer; no longer needed
	now that we include fcntl--.h.

2005-07-02  Jim Meyering  <jim@meyering.net>

	unconditionally.

	* fnmatch.c: Update from gnulib.

	* dup-safer.c, dup2.c, euidaccess.c, fd-safer.c, fileblocks.c:
	* fopen-safer.c, fsusage.c, ftruncate.c, getcwd.c, getcwd.h:
	* getloadavg.c, getopt_.h, getpagesize.h, getugroups.c, group-member.c:
	* human.h, idcache.c, mkdir-p.c, mountlist.c, nanosleep.c, pathmax.h:

	* unsetenv.c, userspec.c, xgethostname.c, xreadlink.c:
	Assume HAVE_UNISTD_H, i.e., include <unistd.h> unconditionally.

2005-07-01  Jim Meyering  <jim@meyering.net>

	* getloadavg.c, mountlist.c, openat.h, save-cwd.c, tempname.c:
	Assume HAVE_FCNTL_H (i.e., include <fcntl.h> unconditionally,
	and don't include <sys/file.h>).

2005-07-01  Paul Eggert  <eggert@cs.ucla.edu>

	* xnanosleep.c: Include timespec.h, since OpenBSD 3.4 <time.h>
	declares only 'struct timespec;' (!).

2005-06-30  Jim Meyering  <jim@meyering.net>

	* stdopen.c: Add copyright.
	Include <fcntl.h> and <unistd.h> unconditionally --
	it seems to be ok to do this, these days.

	* stdopen.c: Rewritten by Paul Eggert.
	Now, the minimum overhead is just two system calls: dup and close.

	* stdopen.c: New file.  As yet unused.
	The minimum overhead is three fstat calls.
	* stdopen.h: New file.

	* argmatch.h [!VERIFY] (VERIFY): Define.
	(ARGMATCH_VERIFY): Use it, so this macro may be used more than
	once in any given scope.

	* xalloc.h (VERIFY_EXPR): Undef before defining, and add a comment.

2005-06-29  Jim Meyering  <jim@meyering.net>

	* mkdir-p.c (make_dir_parents): Don't apply sizeof to a hard-coded
	type name.  Use the variable name instead.
	* idcache.c (getuser, getuidbyname, getgroup, getgidbyname): Likewise.

	get it via root-dev-ino.m4
	(libcoreutils_a_SOURCES): Remove version-etc.c version-etc.h
	and version-etc-fsf.c.

2005-06-24  Paul Eggert  <eggert@cs.ucla.edu>

	* canon-host.c (canon_host) [HAVE_GETADDRINFO]: Use `= { 0, };' to
	initialize local `hint'.  This undoes the previous change, and
	syncs with gnulib.

2005-06-23  Jim Meyering  <jim@meyering.net>

	* Makefile.am (libcoreutils_a_SOURCES): Remove xreadlink.c
	and xreadlink.h.

	* backupfile.c (backup_args): Change a `0' to NULL.

2005-06-22  Paul Eggert  <eggert@cs.ucla.edu>

	* mktime.c: Include <string.h> even if !DEBUG.  (From glibc.)
	(ranged_convert): Don't save conversion in a temporary struct.
	This causes a warning with GCC 4.0.0, and anyway in the typical
	case it's not worth the extra 100 bytes or so of code.
	(ranged_convert, __mktime_internal): When calling a function via a
	pointer P, use P () rather than (*P) (), as we now assume C89 or better.

	* readutmp.c (desirable_utmp_entry): Fix bug where "who -b" and
	"who -r" failed to give output.  Problem reported by Tim Waugh.

2005-06-22  Jim Meyering  <jim@meyering.net>

	* xmalloc.c: Update from gnulib.

2005-06-19  Jim Meyering  <jim@meyering.net>

	xfts.c and xfts.h.

2005-06-16  Jim Meyering  <jim@meyering.net>

	* calloc.c (rpl_calloc): Allocate a 1-byte buffer (not 1xS or Nx1)
	when either N or S is zero.

2005-06-15  Jim Meyering  <jim@meyering.net>

	* mkdir-p.c (make_dir_parents): Don't let a failed chdir($PWD)
	stop us from restricting permissions of just-created absolute-named
	directories.

2005-06-14  Paul Eggert  <eggert@cs.ucla.edu>

	Improve quality of diagnostics on restore_cwd failure.
	* mkdir-p.h (make_dir): Remove.  All uses replaced by mkdir.
	(make_dir_parents): Last arg is now int * (for errno), not bool *.
	* mkdir-p.c (make_dir, make_dir_parents): Likewise.
	Rewrite "mkdir -p" algorithm to avoid the need for "stat"
	each time through the loop.  Do not diagnose restore_cwd failure;
	that is the caller's job (and perhaps the caller does not care).

	* mkdir-p.c (CLEANUP_CWD, CLEANUP): Remove.
	(make_dir_parents): Revamp to avoid need for CLEANUP_CWD, CLEANUP.
	If the file already exists but is not a directory, don't bother
	to try to make its parents.
	Close potential file descriptor leak if we can't chdir("/") (!).
	Don't always return true if chdir($PWD) fails; return true only
	if the requested action was done successfully (except for the
	chdir($PWD)).
	Don't log final directory unless we actually made it.
	Refactor to avoid duplicate code to fix up permissions.
	Don't attempt to fix up parent permissions if chdir($PWD) fails.

2005-06-14  Jim Meyering  <jim@meyering.net>

	* openat.c, openat.h: Reflect s/_die/_fail/ renaming.

	* mkdir-p.c (CLEANUP_CWD): Return *true*, not false when failing
	to restore initial working directory.

	Provide an alternative to exiting immediately upon save_cwd or
	restore_cwd failure.  Now, an application can arrange e.g.,
	to perform a longjump in that case.
	* openat.c: Include dirname.h.
	Use IS_ABSOLUTE_FILE_NAME rather than testing for leading slash.
	(rpl_openat, fdopendir, fstatat): Call openat_save_die
	and openat_restore_die rather than calling error directly.
	Don't include "error.h" or "exitfail.h"; they're no longer needed.

	* openat-die.c (openat_save_die, openat_restore_die): New file.
	* openat.h (openat_save_die, openat_restore_die): Declare and define.

2005-06-13  Jim Meyering  <jim@meyering.net>

	* mkdir-p.c (make_dir_parents): New parameter: different_working_dir,

	unable to return to the initial one.
	* mkdir-p.h (make_dir_parents): Update prototype.

2005-06-12  Jim Meyering  <jim@meyering.net>

	* mkdir-p.c (CLEANUP_CWD): Change one more `return 1' to
	`return false'.  This fixes a bug introduced on 2004-07-30.

2005-06-01  Paul Eggert  <eggert@cs.ucla.edu>

	Use "file name" when talking about file names, instead of "filename"
	or "path", as per the GNU coding standards.
	* mkdir-p.c: Renamed from makepath.c.
	(make_dir_parents): Renamed from make_path.  All callers changed.
	* mkdir-p.h: Likewise.  All includers changed.
	* filenamecat.c: Renamed from path-concat.c.
	(file_name_concat): Renamed from path_concat.  All callers changed.
	[TEST_FILE_NAME_CONCAT]: Renamed from TEST_PATH_CONCAT.

	* euidaccess.c (getuid, getgid, getuid, getegid)
	[!defined _POSIX_VERSION]: Remove decls; not needed these days.
	* idcache.c (getpwuid, getpwnam, getgrgid, getgrnam)
	[!defined _POSIX_VERSION]: Remove decls; not needed these days.
	* pathmax.h: Include <limits.h> unconditionally, since other
	files have been getting away with it for years (MORE/BSD 4.3
	is extinct now).
	* userspec.c (getpwnam, getgrnam, getgrgid)
	[!defined _POSIX_VERSION]: Remove decls; not needed these days.

2005-05-29  Paul Eggert  <eggert@cs.ucla.edu>

	* pathmax.h (_POSIX_PATH_MAX) [!defined _POSIX_PATH_MAX]:
	Define to 256, not 255, as per modern POSIX.

2005-05-27  Paul Eggert  <eggert@cs.ucla.edu>

	* fts.c: Don't worry about debugging on pre-C99-comopatible hosts;
	the configuration hassle isn't worth it.
	Include inttypes.h and stdint.h unconditionally if FTS_DEBUG.
	(LONGEST_MODIFIER, PRIuMAX): Remove.

	* strnumcmp.c, strnumcmp.h, strnumcmp-in.h, strintcmp.c:

2005-05-22  Paul Eggert  <eggert@cs.ucla.edu>

	* fts.c (fd_safer) [_LGPL_PACKAGE]: New static function,
	so that unistd-safer.h (GPL'ed code) need not be included.

2005-05-20  Paul Eggert  <eggert@cs.ucla.edu>

	Split the fts code into GPL'ed and LGPL'ed parts, and fix some
	minor memory-allocation bugs.

	* fts.c: Don't include "cycle-check.h" or "hash.h".
	(setup_dir, free_dir): New functions.
	(enter_dir, leave_dir): Define trivial
	alternatives of _LGPL_PACKAGE.  Move to fts-cycle.c if !_LGPL_PACKAGE.
	(HT_INITIAL_SIZE, ENTER_DIR): Remove.  All uses removed.
	(LEAVE_DIR): Fix typo: pass Fts and Ent to leave_dir.
	(struct Active_dir, AD_compare, AD_hash, enter_dir, leave_dir):
	Move to fts-cycle.c.
	(fts_open): Use setup_dir.
	(fts_close): Use free_dir.
	(fts_read): Have just one copy of the ENTER_DIR code rather than three.
	This adds a label and some gotos, but the alternatives were messier.
	Check for memory allocation failure when entering a dir.
	(fts_stat) [_LGPL_PACKAGE]: Bring back glibc cycle detection code.
	* fts_.h (_LGPL_PACKAGE) [defined _LIBC]: New macro.

	fts_cycle.ht and fts_cycle.state.
	* fts-cycle.c: New file, containing GPL'ed code migrated out of
	fts.c, with the following changes:
	(setup_dir, free_dir): New functions.
	(enter_dir): Now returns bool.  Return true if successful, false
	if memory exhausted.  All callers changed.
	Do not bother partly cleaning up on
	memory allocation failure; that is free_dir's job.
	However, free ad if hash_insert fails, to avoid memory leak.
	(enter_dir, leave_dir): Accommodate change to FTS by inspecting
	fts->fts_options to see which union member to use.

2005-05-20  Eric Blake  <ebb9@byu.net>  (tiny change)

	Use #define rather than a static function, to avoid a warning
	when the function was not used.

2005-05-18  Paul Eggert  <eggert@cs.ucla.edu>

	* canonicalize.c: Include canonicalize.h first, to test interface.
	Include <stddef.h> unconditionally, since we assume C89 now.
	All uses of PTR_INT_TYPE replaced by ptrdiff_t.
	* fts.c: Include fts_.h first, to check interface.
	Do not include intprops.h; no longer needed.

	(fts_build): Use a simpler method (not involving TYPE_SIGNED) to
	decide whether to decrement nlinks.
	* fts_.h: Do not include hash.h or cycle-check.h; no longer needed.

2005-05-09  Paul Eggert  <eggert@cs.ucla.edu>

	* fts_.h (FTS): Use correct type for fts_compar member.
	(FTSENT): New member fts_fts.  Remove members fts_ino, fts_dev,

	(fts_open): Don't cast a function value in a possibly-unsafe way.
	(fts_compar): New function.

	pointers smell the same.

2005-05-08  Paul Eggert  <eggert@cs.ucla.edu>

	* yesno.c: Include getline.h, not ctype.h.

2005-05-05  Paul Eggert  <eggert@cs.ucla.edu>

	* makepath.c (make_path): chdir to "//", not "/", if the file name
	starts with exactly two slashes.  This doesn't solve the problem
	in general but it's better than nothing.  Problem reported by
	Pierre A. Humblet via Eric Blake.

2005-05-01  Paul Eggert  <eggert@cs.ucla.edu>

	* modechange.h (mode_free): Remove; all callers changed to invoke

	New constants.
	(struct mode_change): Moved here from modechange.h.
	(mode_append_entry): Remove.
	(mode_compile): Remove MASKED_OPS arg, since it encouraged
	apps to have incorrect behavior.  Use simpler algorithm for head
	and tail.  Don't futz with umask; that's now the job of mode_adjust.
	Detect more invalid usages rather than having somewhat-random behavior.
	Don't insert an "a=" action, as that leads to incorrect behavior.
	(mode_compile, mode_create_from_ref): Return NULL on error instead
	of an enum, since now there's only one way to have an error.  All
	callers changed.
	(mode_adjust): Accept new arg UMASK_VALUE, and interpret it
	at the correct time.  Simplify calculation of "+u" and its ilk.
	Don't mishandle "+X".
	(mode_free): Remove "register" and localize decls.
	* modechange.h (MODE_X_IF_ANY_X, MODE_COPY_EXISTING):
	(struct mode_change): Move to modechange.c; callers don't
	need to see this stuff.
	(MODE_MASK_EQUALS, MODE_MASK_PLUS, MODE_MASK_MINUS, MODE_MASK_ALL):
	(MODE_INVALID, MODE_MEMORY_EXHAUSTED, MODE_BAD_REFERENCE): Remove.

	(time_zone_table): Remove GMT, UT, UTC entries; they're now in
	universal_time_zone_table.
	(lookup_zone): Prefer universal_time_zone_table to
	local_time_zone_table, so that "GMT" time stamps are allowed in
	London during the summer.  Problem reported by Ian Abbott.

2005-04-11  Paul Eggert  <eggert@cs.ucla.edu>

	warning from gcc-4.

2005-04-08  Paul Eggert  <eggert@cs.ucla.edu>

	(rpl_nanosleep) [!defined SA_NOCLDSTOP]:
	Use siginterrupt to specify that system calls should be interrupted.
	(rpl_nanosleep): Move initialization of suspended closer to call of
	my_usleep.

2005-04-04  Paul Eggert  <eggert@cs.ucla.edu>

	* getdate.y (parser_control): rels_seen is now a boolean, not a
	count, since there's no maximum.  All uses changed.
	Add member dsts_seen.
	(local_zone): Accumulate dsts_seen rather than relying on tm_isdst
	not being INT_MAX.
	(get_date): Initialize dsts_seen, and check that it doesn't go over 1.
	Use pc_rels_seen to decide whther a date is absolute.

	* getdate.y (number): Don't overwrite year.

	* strftime.c (my_strftime): If the underlying strftime returns 0
	(which shouldn't happen), generate nothing instead of returning 0
	immediately, so that nstrftime (NULL, ...) doesn't return 0.

2005-03-15  Paul Eggert  <eggert@cs.ucla.edu>

	* strftime.c (my_strftime): Prepend space to format so that we can
	reliably distinguish strftime failure from empty output on POSIX
	hosts.

2005-03-14  Paul Eggert  <eggert@cs.ucla.edu>

	* mktime.c (TYPE_TWOS_COMPLEMENT, TYPE_ONES_COMPLEMENT,

	when the underlying strftime fails before writing anything into
	that location.

2005-03-11  Jim Meyering  <jim@meyering.net>

	(TYPE_SIGNED): Remove.

2005-03-09  Jim Meyering  <jim@meyering.net>

	Remove workaround for bug in Linux kernel 2.6.8 or thereabouts.
	The workaround isn't strictly needed for POSIX conformance, and

2005-02-25  Paul Eggert  <eggert@cs.ucla.edu>

	* vasnprintf.c (VASNPRINTF) [!USE_SNPRINTF]: Correct the test for
	integer overflow again.  Actually, neither this nor the 2005-01-23
	change fixes any bug on any plausible platform; it's more of a
	code-clarity thing.

	instead of int.
	(my_strftime): Do not mishandle years close to INT_MAX, by doing
	the right thing even if adding 1900 would overflow.  Similarly
	for tm_mon + 1 and tm_yday + 1.
	Make %Y always equivalent to %C%y, and similarly for %G and %g.
	(DO_NUMBER, DO_NUMBER_SPACEPAD): Set digits to d, not a conditional.
	(DO_SIGNED_NUMBER): New macro.
	(my_strftime) [HAVE_TZNAME]: Don't dump core if tp->tm_dst > 1.

	* gethrxtime.h, gethrxtime.c, xtime.h: New files.
	* timespec.h (gettime): Return void, since it always
	succeeds now.  All uses changed.
	* gettime.c (gettime) Likewise.
	[HAVE_NANOTIME]: Prefer nanotime.
	Assume gettimeofday succeeds, as POSIX requires.
	Assime time () succeeds, since other code already does.

	(timespec_subtract): Remove.
	(NANOSLEEP_BUG_WORKAROUND): New constant.
	(xnanosleep): Use gethrxtime rather than gettime; this simplifies
	things considerably.  Use it only on GNU/Linux hosts, since the
	workaround shouldn't be needed elsewhere.

2005-02-20  Neil Conway  <neilc@samurai.com>

	* xgethostname.c (xgethostname): Check for ENOMEM, which is
	returned by OSX/Darwin if the specified buffer is not large

2005-01-29  Jim Meyering  <jim@meyering.net>

	* Makefile.am (libfetish_a_SOURCES): Remove many files from this
	list, now that automake determines their names automatically,
	thanks to the new AC_LIBSOURCES and AC_LIBOBJ uses in the
	corresponding ../m4/*.m4 files.
	(EXTRA_DIST): Add getdate.c here, so that we continue to distribute it.

2005-01-25  Jim Meyering  <jim@meyering.net>

	* path-concat.c: Don't include assert.h.
	(path_concat): Remove assertion that would have triggered
	for ABASE starting with more than one slash.
	Reported by Andreas Schwab.

	* path-concat.c (path_concat): Set *BASE_IN_RESULT
	properly when ABASE is an absolute file name.
	Correct the description of this function.

	for known valid error numbers rather than observed invalid ones.

2005-01-03  Jim Meyering  <jim@meyering.net>

	* utimens.c (futimens): Account for the fact that futimes
	can also fail with errno == ENOSYS in that case.
	Patch from Dmitry V. Levin.

2005-01-03  Paul Eggert  <eggert@cs.ucla.edu>

	* utimens.c (futimens) [HAVE_FUTIMES]: Fall back on utimes if
	futimes fails with errno == ENOENT.  Problem reported by
	Dmitry V. Levin.

2005-01-02  Jim Meyering  <jim@meyering.net>

	* version-etc.c (version_etc_copyright): Update copyright date.

2004-12-31  Jim Meyering  <jim@meyering.net>

	* openat.c (rpl_openat): Correct comment.
	Call free_cwd, to avoid leaking a file descriptor.

2004-12-23  Paul Eggert  <eggert@cs.ucla.edu>

	* getdate.y (YYSTACK_USE_ALLOCA): Define to 0, since there's no
	need to extend the stack.
	(YYINITDEPTH): New macro, so that the initial stack isn't overly
	large.

2004-12-19  Paul Eggert  <eggert@cs.ucla.edu>

	* c-strtod.c (STRTOD): Depend on HAVE_C99_STRTOLD, not
	HAVE_DECL_STRTOLD.

	* alloca_.h: Conditionalize on _GNULIB_ALLOCA_H, not _ALLOCA_H.
	Remove now-obsolete comment about AIX.
	* getdate.y: Include <alloca.h> only if HAVE_ALLOCA.
	(YYSTACK_USE_ALLOCA): Define to 0 if !HAVE_ALLOCA.
	(YYMAXDEPTH): New macro.

2004-12-11  Jim Meyering  <jim@meyering.net>

	* chdir-long.c: Fail via #error if PATH_MAX is not defined, since
	this file is now compiled only on systems that define PATH_MAX.

2004-12-08  Paul Eggert  <eggert@cs.ucla.edu>

	* getdate.y (textint): New member "negative".
	(time_zone_hhmm): New function.
	Expect 14 shift-reduce conflicts, not 13.
	(o_colon_minutes): New rule.
	(time, zone): Use it to add support for +HH:MM, UTC+HH:MM.
	(yylex): Set the "negative" member of signed numbers.

2004-12-06  Jim Meyering  <jim@meyering.net>

	* Makefile.am (libfetish_a_SOURCES): Begin removing .c and .h file
	names, as they are added to AC_LIBSOURCES directives in the
	corresponding m4/*.m4 files.

2004-12-05  Jim Meyering  <jim@meyering.net>

	Currently, fpending.m4 punts (by defining PENDING_OUTPUT_N_BYTES
	to 1) if it doesn't find a valid expression for the replacement
	function.  Before this change, that might have gone undetected
	for some time.  Now, we'll catch it close to the source.

	* t-fpending.c: New file.  Test the __fpending function.
	This ensures that if there is an error in the definition of the
	PENDING_OUTPUT_N_BYTES expression, we'll find about it right away;
	that value is used only in the rare event that close_stdout's
	fclose fails with EBADF.
	* Makefile.am (unit-test): New target.
	(check): Depend on it.
	(noinst_PROGRAMS): Define.
	(LDADD): Define.
	* Makefile.am (unit-test): Depend on t-fpending.
	Make the target .PHONY.

2004-12-02  Paul Eggert  <eggert@cs.ucla.edu>

	* openat.c: Include "openat.h" before other include files.
	Include "exitfail.h".
	(openat): Remove #undef; no longer needed now that we include openat.h
	first.
	(rpl_openat): Add comment about mode_t promotion.  Simplify
	code a bit by moving initializations around.  Use exit_failure
	rather than EXIT_FAILURE.
	* openat.h: Add copyright and authorship notice.
	(AT_FDCWD): Use the same value Solaris 9 uses, except of type
	'int' not 'unsigned int'.

	* save-cwd.c: Include "save-cwd.h" before other include files.
	(O_DIRECTORY): Remove; not needed here, since "." must be
	a directory.  All uses removed.
	(save_cwd): Use __sgi || __sun, not sun || __sun.  __sun is
	universal on Suns, and we also need to test for IRIX.
	Revamp code to use 'if' rather than '#if'.
	Avoid unnecessary comparison of cwd->desc to 0.

2004-12-01  Paul Eggert  <eggert@cs.ucla.edu>

	* hard-locale.c: Assume <locale.h> exists.
	Include "strdup.h".
	(GLIBC_VERSION): New macro.
	(hard_locale): Assume setlocale exists.
	Rewrite to avoid #ifdef.
	Use strdup rather than malloc + strcpy.
	* human.c: Assume <locale.h> exists.
	(human_readable): Assume localeconv exists.

2004-11-30  Paul Eggert  <eggert@cs.ucla.edu>

	* getcwd.c (is_ENAMETOOLONG): New macro.
	(__getcwd.c): Don't restore errno; glibc doesn't.
	[HAVE_PARTLY_WORKING_GETCWD && !defined AT_FDCWD]: Try system getcwd
	first, falling back to our code only if its results look suspicious.
	Ensure that the resulting buffer is only as large as necessary.

	* readutmp.c: Include readutmp.h first.
	Include <errno.h>, since readutmp.h no longer does that.
	* readutmp.h: Don't include <errno.h>,
	<sys/param.h>, <time.h>; not needed to establish interface.
	(errno): Remove decl.
	(HAVE_STRUCT_XTMP_UT_TYPE): Remove; no longer needed.
	(UT_TYPE_EQ, UT_TYPE_NOT_DEFINED, UT_TYPE_BOOT_TIME,
	UT_TYPE_USER_PROCESS, IS_USER_PROCESS): New macros.

2004-11-30  Jim Meyering  <jim@meyering.net>

	Change the name of the robust chdir function from chdir to chdir_long.
	* save-cwd.c: Include chdir-long.h rather than chdir.h.
	(restore_cwd): Use chdir_long, not chdir.
	* chdir-long.c: Renamed from chdir.c.
	* chdir-long.h: Renamed from chdir.h.
	[!defined PATH_MAX]: Define chdir_long to chdir on systems like the Hurd.
	* Makefile.am (libfetish_a_SOURCES): Reflect name changes.

	* chdir.c (O_DIRECTORY): Define, if necessary.
	(memchrcspn): Tiny wrapper around memchr.
	(rpl_chdir): Use memchrcspn rather than strcspn.

2004-11-28  Jim Meyering  <jim@meyering.net>

	* openat.c (rpl_openat): Also accept optional mode parameter.
	* openat.h (rpl_openat): Adjust prototype.

	* save-cwd.c: Include "chdir.h", so that if save_cwd/getcwd
	saves a name longer than PATH_MAX, restore_cwd's chdir can use it.

	* Makefile.am (libfetish_a_SOURCES): Add chdir.h and openat.h.

	This is a robust version of chdir, in that it can handle directory
	names longer than PATH_MAX.
	* chdir.c, chdir.h: New file.
	* openat.c, openat.h: New files.

2004-11-25  Paul Eggert  <eggert@cs.ucla.edu>

	Fix problems reported by Scott S. Tinsley for HP-UX 11.11 using
	HP's ANSI C compiler.
	* fsusage.c (statvfs) [HAVE_SYS_STATVFS_H]: Remove decl.
	Declaring int functions causes warnings on some modern systems and
	shouldn't be needed to compile on ancient ones.
	* same.c (MIN) [defined MIN]: Don't define, since it's already
	defined.

	* mempcpy.c, mempcpy.h: New files, taken from gnulib.
	* Makefile.am: (libfetish_a_SOURCES): Add getcwd.h, mempcpy.h.
	* getcwd.c: Replace by a copy of glibc/sysdeps/posix/getcwd.c, but
	with the following changes.
	(__set_errno): Parenthesize properly.
	Include <stdbool.h>.
	(MIN, MAX, MATCHING_INO): New macros.
	(__getcwd): Define with prototype, not K&R form.
	Use heuristics to allocate default buffer on stack if possible.
	If AT_FDCWD is defined, use openat and fstatat to avoid O(N**2)
	behavior, and to avoid the PATH_MAX limit when computing
	../../../../...
	Use MATCHING_INO to compare inode number to file.
	Check for arithmetic overflow in size calculations.
	Fix bug in reallocation of dot array that caused getcwd to fail
	on directories nested deeper than 75.
	Be more careful about saving errno on error.
	Do not use realloc; use only free+malloc, as this is a bit
	more flexible and avoids a needless copy operation.
	Do not inspect st_dev and st_ino for symbolic links; POSIX
	doesn't specify the latter.
	Check for closedir errors.
	Avoid needless casts.
	Use "#ifdef weak_alias" around weak_alias, to be like other
	glibc code.
	The following changes to getcwd.c have effect only when used in
	gnulib; they have no effect inside glibc proper.
	(#pragma alloca) [defined _AIX && !defined __GNUC__]: Remove,
	as alloca isn't used.
	(alloca, __alloca): Likewise.
	[!_LIBC]: Include "getcwd.h", "mempcpy.h".
	Include <stddef.h>, <stdlib.h>, <string.h>, <limits.h>
	unconditionally, as gnulib assumes C89 or better.
	Do not include <sys/param.h>.
	(errno) [!defined __GNU_LIBRARY__ && !defined STDC_HEADERS]: Remove
	no-longer-necessary 'extern int errno' decl; gnulib assumes C89 or
	better.
	(NULL) [!defined NULL]: Remove; we assume C89 or better.
	Include <dirent.h> in a way that is compatible with modern Autoconf.
	(_D_ALLOC_NAMELEN, _D_EXACT_NAMLEN):
	New macros, if not already defined.
	Include <unistd.h> if _LIBC, not if __GNU_LIBRARY__.
	Use "_LIBC", not "defined _LIBC", for consistency.
	(HAVE_MEMPCPY): Remove; no longer needed now that gnulib has
	a mempcpy module.
	(__lstat, __closedir, __opendir, __readdir) [!_LIBC]: New macros.
	(GETCWD_RETURN_TYPE): Remove.  All uses replaced by char *.
	* xgetcwd.c: David MacKenzie's old code was removed, so give
	credit only to Jim Meyering and adjust the copyright dates.
	Do not include <limits.h>, <stdio.h>, <sys/types.h>,
	<stdlib.h>, <unistd.h>, "pathmax.h".
	Instead, include "xgetcwd.h" (first) and "getcwd.h".
	(INITIAL_BUFFER_SIZE): Remove.
	(xgetcwd): Rely on getcwd, since we now depend on a reliable one.

2004-11-23  Paul Eggert  <eggert@cs.ucla.edu>

	* utimens.c (__attribute__, ATTRIBUTE_UNUSED): New macros.
	(futimens): New function, which uses futimes if available.
	(futimens, utimens): Support timespec==NULL, with same semantics
	as utime and utimens.
	* utimens.h (futimens): New decl.

2004-11-23  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

	* getopt_.h: Re-addition of __getopt_argv_const caused
	redefinition warnings. To avoid them, include the defines
	in `#if !defined __need_getopt ... #endif'. The only place
	where __getopt_argv_const is used is in definitions
	of getopt_long and getopt_long_only below, which are as well
	protected by `#ifndef __need_getopt'.
	[defined __GETOPT_PREFIX && !defined __need_getopt]: Undef
	__need_getopt after including <stdio.h> and <unistd.h> These
	headers might have defined it.

2004-11-23  Jim Meyering  <jim@meyering.net>

	* closeout.c: Revert last change, since it seems EBADF is always
	defined.

2004-11-22  Jim Meyering  <jim@meyering.net>

	* closeout.c (EBADF): Fail with `#error ...' if it's not defined,
	asking the user to report the problem.

2004-11-17  Paul Eggert  <eggert@cs.ucla.edu>

	* realloc.c (rpl_realloc): Call 'free' if n==0, since realloc
	might fail.  Problem reported by Yoann Vandoorselaere.
	* calloc.c (rpl_calloc): Defend against buggy calloc implementations
	that mishandle size_t overflow.

2004-11-16  Paul Eggert  <eggert@cs.ucla.edu>

	* xgetcwd.c: Include <limits.h>, for PATH_MAX.
	(xgetcwd): Set errno correctly when failing.
	Work around Solaris 9 bug: getcwd sets errno==ERANGE even though
	the failure is actually due to a PATH_MAX problem.

	Further getopt changes to make it more likely that glibc will
	buy the changes back.
	* getopt.c (POSIXLY_CORRECT): New constant.
	(getopt): Use it, so to preserve glibc semantic
	* getopt1.c (getopt_long, getopt_long_only): Arg is char * const *
	when compiling for libc.
	* getopt_.h (__getopt_argv_const): Bring it back.
	(getopt_long, getopt_long_only): Use it.

	* getopt.c (_getopt_initialize, _getopt_internal_r, _getopt_internal):
	New arg POSIXLY_CORRECT.  All callers changed.
	(getopt): Argv is now char * const *, as per standard.
	(_getopt_internal_r, _getopt_internal): Argv is now char **,
	not char *__getopt_argv_const *.
	* getopt1.c (getopt_long, _getopt_long_r, getopt_long_only,
	_getopt_long_only_r): Likewise.
	* getopt_.h (getopt, getopt_long, geopt_long_only): Likewise.
	* getopt_int.h (_getopt_internal, _getopt_internal_r,
	_getopt_long_r, _getopt_long_only_r): Likewise.
	* getopt_.h (__getopt_argv_const): Remove.
	(getopt): Argv is now char * const *, as per standard.

	* canon-host.c: Include "strdup.h".
	(canon_host): Use getaddrinfo if available, so that IPv6 works.
	Use strdup instead of malloc/strcpy to duplicate strings.

	* getdate.y (tORDINAL): New token.
	(day, relunit): Allow it for relative times.
	(relative_time_table): Use tORDINAL for ordinals.

2004-11-15  Paul Eggert  <eggert@cs.ucla.edu>

	* human.h (LONGEST_HUMAN_READABLE): Add 1 for space before unit.
	(human_space_before_unit): New constant.
	* human.c (human_readable): Support it.

2004-11-14  Jim Meyering  <jim@meyering.net>

	* closeout.c (close_stdout): Don't fail just because stdout was
	closed initially, since some programs don't write to stdout in the
	normal course of operation (other than --version and --help), and
	we don't want this function to make e.g. `cp 1 2 >&-' fail.
	But do fail if it was closed and someone has tried to write to it.
	E.g., printf foo >&-

	* __fpending.c, __fpending.h: Restore these files.
	They're useful after all.
	* Makefile.am (libfetish_a_SOURCES): Add __fpending.h.

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

	* getopt.c, getopt1.c, getopt_.h, getopt_int.h:
	Sync from gnulib.

2004-11-10  Paul Eggert  <eggert@cs.ucla.edu>

	* allocsa.h, mbswidth.c, mktime.c, readlink.c, getdate.y,
	quotearg.c, strftime.c: Sync from gnulib.

2004-11-06  Jim Meyering  <jim@meyering.net>

	* __fpending.c, __fpending.h: Remove files.

	* Makefile.am (libfetish_a_SOURCES): Remove __fpending.h, now
	that it's no longer used.

	Ensure that no close failure goes unreported.
	* closeout.c (close_stdout): Always close stdout.  I.e., don't
	return early when it seems there's nothing to flush.
	Don't include __fpending.h.

2004-11-03  Paul Eggert  <eggert@cs.ucla.edu>

	* unsetenv.c: New file, from gnulib.  Needed for new getdate.y.
	* Makefile.am (libfetish_a_SOURCES): Remove setenv.c.
	* xreadlink.c: Sync from gnulib.

2004-11-03  Jim Meyering  <jim@meyering.net>

	* Makefile.am (libfetish_a_SOURCES): Add setenv.c and setenv.h.

2004-11-02  Paul Eggert  <eggert@cs.ucla.edu>

	* getdate.y, getpass.c, setenv.h: Sync from gnulib.

2004-10-29  Paul Eggert  <eggert@cs.ucla.edu>

	* getdate.y, getpagesize.h, mktime.c: Sync from gnulib.

2004-10-24  Paul Eggert  <eggert@cs.ucla.edu>

	* mktime.c (leapyear): Arg is long int, not int.
	Change imported from gnulib.

2004-10-17  Paul Eggert  <eggert@cs.ucla.edu>

	Sync from gnulib.
	* diacrit.c, diacrit.h: Add copyright notice.
	* getpass.c (fflush_unlocked, flockfile, funlockfile)
	(fputs_unlocked, putc_unlocked) [!_LIBCS && !USE_UNLOCKED_IO]: Map
	to real functions.

2004-10-13  Jim Meyering  <jim@meyering.net>

	* fts.c (fts_read): When about to fail (by returning NULL) due
	to a failed fchdir or failed fts_safe_changedir call, set
	`sp->fts_cur = p'.  Do this by removing the explicit `return NULL;'
	statements and setting p->fts_errno so execution falls through
	to the common-case code below.  Otherwise, after such a failure,
	calling fts_close would attempt to free an already-freed buffer.
	Reported by Luis Lopez Lopez in http://bugs.debian.org/276352.

2004-10-04  Paul Eggert  <eggert@cs.ucla.edu>

	Sync from gnulib.

	* xalloc.h (xmemdup): Renamed from xclone.
	* xmalloc.c (xmemdup): Likewise.

	* argmatch.c, closeout.c, error.c, exclude.c, getdate.y,
	getndelim2.c, getpass.c, getusershell.c, linebuffer.c,
	md5.c, mountlist.c, posixtm.c, readtokens.c, readutmp.c,
	regex.c, sha1.c, version-etc.c, yesno.c:
	Include "unlocked-io.h" only if USE_UNLOCKED_IO.
	* unlocked-io.h: Don't worry about USE_UNLOCKED_IO; that's now
	the includer's responsibility.

2004-10-03  Paul Eggert  <eggert@cs.ucla.edu>

	Sync from gnulib.
	* dirfd.h, getpagesize.h: Add copyright notice.
	* vasnprintf.c: (VASNPRINTF): Set errno=EOVERFLOW if the output is
	too long.
	* vasnprintf.h: Doc fix.
	* vasprintf.c: Don't include <limits.h>.
	(vasprintf): Rely on vasnprintf to set errno=EOVERFLOW.

2004-09-23  Paul Eggert  <eggert@cs.ucla.edu>

	* modechange.c (mode_compile): Don't decrement a pointer that
	points to the start of a string, as the C Standard says the
	resulting behavior is undefined.

2004-09-22  Jim Meyering  <jim@meyering.net>

	* getopt.c: Remove extraneous spaces before TAB.
	* getopt_.h: Likewise.

	* backupfile.c: Remove trailing blanks.
	* euidaccess.c: Likewise.

2004-09-13  Paul Eggert  <eggert@cs.ucla.edu>

	* backupfile.h (enum backuptype): Rename none -> no_backups,
	simple -> simple_backups, numbered_existing ->
	numbered_existing_backups, numbered -> numbered_backups
	to avoid shadowing problems.  All uses changed.
	* argmatch.c (enum backuptype): Likewise.
	* backupfile.c (check_extension, numbered_backup):
	Rename locals to avoid shadowing 'basename'.
	* backupfile.h (VALID_BACKUP_TYPE): Don't evaluate arg more than
	once.

2004-09-02  Paul Eggert  <eggert@cs.ucla.edu>

	Port to diet libc.  Problem reported by Felix von Leitner in
	<http://lists.gnu.org/archive/html/bug-coreutils/2004-08/msg00171.html>
	* fts.c (fts_stat, fts_open, fts_read): Use "unsigned short int"
	rather than the unportable "u_short", and similarly for u_int.
	* fts_.h (FTSENT): Likewise.

2004-08-19  Paul Eggert  <eggert@cs.ucla.edu>

	* getopt.c, getopt1.c: Sync from gnulib.
	* getopt_.h: Renamed from getopt.h (this syncs from gnulib).
	* Makefile.am (libfetish_a_SOURCES): Remove getopt.c, getopt.h,
	getopt1.c, getopt_int.h.
	(BUILT_SOURCES, EXTRA_DIST, all-local, $(lib_OBJECTS), getopt.h,
	MOSTLYCLEANFILES): Add current gnulib snippet for getopt.
	* .cppi-disable: Add getopt_.h, getopt_int.h.
	* .cvsignore: Add getopt.h.

2004-08-18  Paul Eggert  <eggert@cs.ucla.edu>

	* userspec.c: Don't use <alloca.h>, so that we don't use alloca on
	strings on unbounded length.  alloca's performance benefits aren't
	that important here.
	(V_STRDUP): Remove.
	(parse_with_separator): New function, with most of the internals
	of the old parse_user_spec.  Allow user to omit both user and group,
	for compatibility with FreeBSD.
	Clone only the user name, not the entire spec.
	Do not set *uid, *gid unless entirely successful.
	Avoid memory leak in some failing cases.
	Fix regression for USER.GROUP reported by Dmitry V. Levin in
	<http://lists.gnu.org/archive/html/bug-coreutils/2004-08/msg00102.html>
	(parse_user_spec): Rewrite to use parse_with_separator.

2004-08-11  Paul Eggert  <eggert@cs.ucla.edu>

	* fts.c (O_DIRECTORY): Define to 0 if the system doesn't define.

	* settime.c (settime): Recode to avoid warning with Sun Forte C 6U2.

	* obstack.c: Include <inttypes.h> and <stdint.h> if available.
	(union fooround): Use uintmax_t, not long int.
	The rest is a merge from libc:
	[defined _LIBC]: Include <shlib-compat.h>.
	(_obstack) [defined _LIBC]: Remove after 2.3.4.

	* xgethostname.c: Do not include error.h.  (merge from gnulib).

	* fnmatch.c (WIDE_CHAR_SUPPORT): Don't set to 1 if missing
	wmemchr or wmemcpy.  Problem reported by Robert Dahlem
	for Reliant Unix 5.43.

	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>

	* canonicalize.h, cycle-check.h, stat-macros.h, strdup.h,

	* obstack.h: Add white space.

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

	* yesno.c: Include yesno.h first.
	(yesno): Return bool, not int.

	* 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
	nontrivial.
	* fts.c: Likewise.

	(FTS.fts_nitems): Now size_t, not int, for hosts that allow more
	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.

	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.
	(fts_alloc): Simplify allocation code, now that fts_statp is an array
	and not a pointer.

	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.
	* argmatch.c: Likewise.  Use bool when appropriate.

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.

	* 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

2004-04-03  Dmitry V. Levin  <ldv@altlinux.org>

	* Makefile.am (libfetish_a_SOURCES): Add canonicalize.c
	unconditionally.
	* canonicalize.h (canonicalize_mode_t): New type.

	(canonicalize_filename_mode): New function, based on
	canonicalize_file_name, supports three canonicalize modes.
	(canonicalize_file_name)
	[!HAVE_CANONICALIZE_FILE_NAME && !HAVE_RESOLVEPATH]: Use it.

2004-07-05  Jim Meyering  <jim@meyering.net>

	* path-concat.c (path_concat): Improve comment.  From Paul Eggert.

2004-07-02  Paul Eggert  <eggert@cs.ucla.edu>

	* canonicalize.c (canonicalize_file_name): Assume that path_concat
	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.
	(longest_relative_suffix): New function.
	(path_concat): Use it.  Assume first argument is not NULL.
	Port to DOS.  Omit redundant separators.
	Report an error instead of returning NULL.
	Use mempcpy instead of memcpy.
	(xpath_concat): Remove: not declared or used.

2004-06-30  Paul Eggert  <eggert@cs.ucla.edu>

	* dirname.h (FILE_SYSTEM_PREFIX_LEN): Renamed from
	FILESYSTEM_PREFIX_LEN.  All uses changed.

	read_filesystem_list.  All definitions and uses changed.

2004-06-24  Jim Meyering  <jim@meyering.net>

	* obstack.h (obstack_base): Fix parentheses.  From Paul Eggert.

2004-06-20  Jim Meyering  <jim@meyering.net>

	* obstack.h (obstack_base): Cast to (void *), per documentation.

2004-06-11  Paul Eggert  <eggert@cs.ucla.edu>

	* readutmp.c (extract_trimmed_name): Don't apply strchr to a
	non-string; this leads to undefined behavior.

2004-05-18  Paul Eggert  <eggert@cs.ucla.edu>

	* fts.c (fts_stat, fts_alloc): Always allocate and use a struct
	stat, even if the user isn't interested in the results.
	This prevents a core dump in cycle_check when FTS_NOSTAT is set.
	* lchown.c (lchown): Return EOPNOTSUPP if not supported; this
	is what POSIX-2004 specifies.
	* lchown.h (EOPNOTSUPP): Define if not defined.
	(ENOSYS): Remove.

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

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".

	* 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.

2003-07-17  Paul Eggert  <eggert@twinsun.com>

	* Makefile.am (BUILT_SOURCES): Use `BUILT_SOURCES += $(STDBOOL_H)'
	rather than `all-local: $(STDBOOL_H)'.  The latter didn't force
	creation of stdbool.h before most other targets.
	Likewise for $(ALLOCA_H).

	Don't emit diagnostics.  Let callers do that.
	* save-cwd.c: Don't include "error.h".

2003-07-09  Jim Meyering  <jim@meyering.net>

	* mktime.c: Update from gnulib.
	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>

	having it depend on HAVE_SYS_TYPES_H.

2003-06-18  Jim Meyering  <jim@meyering.net>

	* inttostr.h (PARAMS): Remove.  All uses removed.

	Merge in change from gnulib.
	* makepath.c: Remove block of alloca-related code in favor
	of an unconditional `#include <alloca.h>'.

	* xalloc.h: Include <stddef.h>.
	Remove unnecessary parentheses.
	Use `1990-2000' notation in Copyright line until Emacs'
	copyright-update function learns how to handle a comma-separated
	list of years that spans a line boundary.

	* Makefile.am (libfetish_a_SOURCES): Add getdelim2.c and getdelim2.h.

	* getline.c (getdelim2): Move this function into its own file.

	xstrtol.h: Likewise.
	* filemode.h, hard-locale.h, memcoll.h, modechange.h, physmem.h, same.h,
	* strverscmp.h: Do not include config.h; no longer needed.
	Anyway, config.h should always be included before any other file.

2003-06-17  Jim Meyering  <jim@meyering.net>

	* getline.c: Update from gnulib.

	Merge in changes from gnulib.
	* hash.c: Include <stdbool.h> unconditionally.

	* rename.c: #undef rename before defining rpl_rename.
	[HAVE_CONFIG_H]: Guard inclusion of config.h.
	* putenv.c: Include <stddef.h> rather than <sys/types.h>,
	as we merely need size_t.
	* realloc.c: Likewise.
	* 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
	our interface, instead of including <sys/types.h>
	(memcoll): Fall back on a simple algorithm using
	memcmp if strcoll doesn't work.

	(HAVE_LIMITS_H): Remove.  Assume it's 1.
	(__P): Remove; not used.
	(CHAR_BIT, INT_MIN, INT_MAX): Remove; <limits.h> defines them.
	(mktime, not_equal_tm, print_tm, check_result,
	main): Use prototypes.  Use const * where appropriate.
	(main): Fix typo in testing code that uncovered by above changes.
	(Local Variables): Remove -DHAVE_LIMITS_H from compile-command.

2003-06-04  Paul Eggert  <eggert@twinsun.com>

2003-05-13  Jim Meyering  <jim@meyering.net>

	* setenv.c (setenv): Don't apply cast to argument of free.
	* putenv.c (rpl_putenv): Likewise.
	* alloca.c (alloca): Likewise.

2003-05-12  Jim Meyering  <jim@meyering.net>

	* ftw.c (ftw_startup): Always call free_cwd after restore_cwd.
	Reported by Matti Aarnio as
	https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=90563.
	Forwarded by Tim Waugh.

	* strftime.c (my_strftime): Let the `-' (no-pad) flag affect
	the space-padded-by-default conversion specifiers, %e, %k, %l.

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.
	(ftw_arr): Likewise
	Reported by Olatunji Oluwabukunmi Ruwase.

	Make it less likely that the above can happen again.
	* ftw.c (struct dummy): Ensure that at least the number of
	initializers matches the number of members in the corresponding enum.
	* ftw_.h (enum Ftw_option): Name this previously-anonymous enum.
	(enum Ftw_option) [FTW_N_MEMBERS]: New member.

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
	by also updating `dest' when rpath may be changed by xrealloc.

2003-04-15  Jim Meyering  <jim@meyering.net>

	* getloadavg.c: Remove (or replace-with-TAB(s) to retain alignment)
	each sequence of spaces before a TAB character.
	* md5.c, getopt.c, getopt.h, obstack.h, strftime.c: Likewise.

2003-04-11  Jim Meyering  <jim@meyering.net>

	* readutmp.c: Include <string.h> and <stdlib.h> unconditionally.

	* group-member.c, idcache.c, mountlist.c, readtokens.c, readutmp.c:
	* bumpalloc.h: Remove anachronistic casts of xmalloc, xrealloc,
	and xcalloc return values.

	* xalloc.h (PARAMS): Remove definitions and uses.
	(XMALLOC, XCALLOC, XREALLOC): Remove unnecessary casts.

	* xmalloc.c: Remove use of PARAMS.

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.
	Add test-cases for DOS filenames. Declare program_name.
	(main): Set up program_name.

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.
	[STAT_MACROS_BROKEN]: Undefine S_ISLNK.
	(S_ISLNK): Define, if necessary.
	Based on a patch from Rich Dawe.

	From Paul Eggert.

2003-03-17  Richard Dawe  <rich@phekda.freeserve.co.uk>

	* fchdir-stub.c: New file: trivial stub for fchdir.

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.
	* lstat-stub.c (lstat): 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
	have required an ANSI (c89) compiler for a year or two.
	(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.
	* readlink-stub.c: New file: trivial stub for readlink.

2003-03-09  Paul Eggert  <eggert@twinsun.com>

	* argmatch.c (EXIT_FAILURE): Define if the system doesn't.
	Reported by Bruce Becker; see:
	http://mail.gnu.org/archive/html/bug-bison/2003-03/msg00017.html

2003-03-03  Paul Eggert  <eggert@twinsun.com>
	    Bruno Haible  <bruno@clisp.org>

	* mbswidth.h: Include <wchar.h>. Needed for UnixWare 7.1.1.
	Reported by John Hughes, see
	http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00030.html

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.

2003-03-06  Jim Meyering  <jim@meyering.net>

	* ftw.c (ftw_startup): Declare `func' parameter to be of type
	NFTW_FUNC_T, not void* which may be smaller on 64-bit systems.
	Remove now-unnecessary cast.
	(FTW_NAME): Cast func argument to type `NFTW_FUNC_T'.

2003-03-05  Jim Meyering  <jim@meyering.net>

	* physmem.c (ARRAY_SIZE): Define it.

2003-03-04  Jim Meyering  <jim@meyering.net>

	* makepath.c (CLEANUP_CWD): Call error here, now that restore_cwd
	no longer does it.

	* save-cwd.h (restore_cwd): Update prototype.
	* save-cwd.c (restore_cwd): Remove two parameters.
	Simplify.  Don't call error upon failure.  Let callers do that.
	(save_cwd): Mention that Irix 5.3 has the same problem as SunOS 4
	when auditing is enabled.  But don't bother updating the #if.

	* xgetcwd.c (xgetcwd): Improve comment.

	* getcwd.c: New file.

2003-02-28  Jim Meyering  <jim@meyering.net>

	* ftw.c (ftw_startup): Return -1 if alloca fails.

2003-02-28  Jim Meyering  <jim@meyering.net>

	member to NULL before returning.  From NetBSD.

	* fts.c (fts_children): If fchdir fails, close file descriptor
	before returning.  From NetBSD.

2003-02-27  Jim Meyering  <jim@meyering.net>

	* physmem.c (physmem_total, physmem_available): Add comments.
	From Kaveh Ghazi.

	* physmem.c: Merge in portability changes from gcc/libiberty

	(ftw_startup): Likewise.

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

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>

	umaxtostr.c.
	(EXTRA_DIST): Add inttostr.c.
	* inttostr.c, inttostr.h, imaxtostr.c, offtostr.c, umaxtostr.c:
	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.
	* safe-read.h: Update prototype.
	(SAFE_READ_ERROR): Define.

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.

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.

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

	* Makefile.am (Makefile): Don't depend on $(BUILT_SOURCES).

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

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

	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

	(STREQ): Define.

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

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

	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>

	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.

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).

2001-11-18  Jim Meyering  <jim@meyering.net>

	* tempname.c [!HAVE_DECL_GETENV]: Declare getenv to avoid warning
	on SunOS 4.

	* Makefile.am (Makefile): Depend on $(BUILT_SOURCES), so those
	files will be created before anything else.

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".

	Include config.h.
	(rpl_mkstemp): Rename from mkstemp.
	Protoize.

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>

	in argmatch_to_argument call.

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

	* hash.c (hash_clear): Fix a bug that could lead to an infloop or
	e.g., a fault due to an attempt to free a NULL pointer.

2001-11-01  Jim Meyering  <jim@meyering.net>

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

	* hash.c (hash_print) [TESTING]: Clean up.

2001-10-22  Paul Eggert  <eggert@twinsun.com>

	* 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.
	Do not check for HAVE_DECL_STRERROR_R missing unless STRERROR_R_CHAR_P.
	Use strerror_r that is only a macro, even if it is not a function.
	(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).
	* hash-pjw.h: New file.

2001-09-30  Jim Meyering  <jim@meyering.net>

	* mountlist.c [MOUNTED_GETFSSTAT]:
	Include <sys/ucred.h>, for Apple Darwin.
	Include sys/mount.h and sys/fs_types.h only if available.
	(FS_TYPE): Define.
	(read_filesystem_list): Use FS_TYPE.

2001-09-29  Paul Eggert  <eggert@twinsun.com>

	* exclude.c (excluded_filename): 0 -> false, since it's
	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>

	* gettimeofday.c (rpl_gettimeofday): Declare local variable `result'.

2001-09-23  Jim Meyering  <jim@meyering.net>

	* mountlist.c: Remove useless parentheses in #if directives.
	(MOUNTED) [!defined MOUNTED]: Define to _PATH_MOUNTED, for when
	the deprecated MOUNTED symbol is no longer defined in mntent.h.

2001-09-22  Jim Meyering  <jim@meyering.net>

	* localcharset.c: Update from latest gettext.
	* config.charset: Likewise.

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>

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

	* xgetcwd.c: Fix the !HAVE_GETCWD_NULL code to behave more
	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.c: New file.
	* 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>

	* xstrtol.h: Add copyright notice.
	(_DECLARE_XSTRTOL): Improve quality of diagnostic for
	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]:
	Simply `return getcwd (NULL, 0);'.

	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>

	(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.

	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.

	(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.

	Required at least for Vax Ultrix4.3, which doesn't define uint64_t.
	Reported by John David Anglin.

2001-03-10  Bruno Haible  <haible@clisp.cons.org>

	* localcharset.c (locale_charset): Allow wildcard syntax. Also resolve

	From Bruno Haible.

2001-03-06  Bruno Haible  <haible@clisp.cons.org>

	* localcharset.c (locale_charset): Don't use setlocale(LC_CTYPE,NULL).
	Don't return NULL.
	* unicodeio.c (print_unicode_char): Simplify accordingly.

2001-03-06  Bruno Haible  <haible@clisp.cons.org>

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.

	* tempname.c (<config.h>): Include if HAVE_CONFIG_H.

	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.

	(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.

	(default_shells): Prepend ADDITIONAL_DEFAULT_SHELLS.
	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'.

	* userspec.c (parse_user_spec): Fix typo: s/u/g/.

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

2000-11-22  Paul Eggert  <eggert@twinsun.com>

	* 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.

2000-11-06  Paul Eggert  <eggert@twinsun.com>

	* getusershell.c (setusershell): Use rewind rather than
	fseek/fseeko, to avoid configuration hassles with fseeko.

	last one in a bucket, advance to the next bucket.

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

	* fnmatch.c: Do not comment out all the code if we are using
	the GNU C library, because in some cases we are replacing buggy
	code in the GNU C library itself.

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

	* error.h, getline.h, modechange.h:
	Remove "2000" from Copyright line, as the file hasn't been
	changed this year other than in the copyright notice.

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

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

	* fnmatch.c (FOLD): Do not assume that characters are unsigned.
	(fnmatch): Fix some FNM_FILE_NAME and FNM_LEADING_DIR bugs,

2000-10-29  Greg Louis  <glouis@dynamicro.on.ca>

	* regex.h (__restrict_arr): Move definition out of #ifndef block.

2000-10-26  Jim Meyering  <jim@meyering.net>

	* 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.

	* getopt.c (_getopt_internal): Update from glibc.

2000-09-09  Jim Meyering  <jim@meyering.net>

	* quotearg.c: Rename ISASCII to IN_CTYPE_DOMAIN, so people don't
	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.
	Include xstrtol.h.
	(CHAR_BIT, TYPE_SIGNED, TYPE_MINIMUM, TYPE_MAXIMUM): Define.
	(UID_T_MAX, GID_T_MAX, MAXUID, MAXGID): Define.

2000-08-07  Paul Eggert  <eggert@twinsun.com>

	Standardize on "memory exhausted" instead of "Memory exhausted"
	or "virtual memory exhausted".

	source code modules.  From Paul Eggert.

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

	* regex.c (SET_HIGH_BOUND, MOVE_BUFFER_POINTER,

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>

	* makepath.c (make_path): Quote the other instance, too.

	* quotearg.c (N_STATIC_SLOTVECS): Define.

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

	* mbswidth.c (_XOPEN_SOURCE):
	Don't define; this causes problems on Solaris 7.
	(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>

	* quotearg.c: Streamline by invoking multibyte code only if needed.

	(noinst_HEADERS): Add quote.h.

	* quote.c (quote, quote_n): New file.  Two functions taken verbatim

2000-07-10  Paul Eggert  <eggert@twinsun.com>

	From a suggestion by Bruno Haible.
	* quotearg.c (mbrtowc): Do not use HAVE_WCHAR_H in the definition.
	Use defined mbstate_t, not HAVE_MBSTATE_T_OBJECT,

	http://www.cl.cam.ac.uk/~mgk25/ucs/quotes.html

	tailor the locale-specific quoting behavior by providing
	translations for {LEFT QUOTATION MARK} and {RIGHT QUOTATION MARK}.

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.
