	which was an int, everywhere.
	* tar.c (decode_options): Initialise main_command_option.
	(set_main_command_option): New function to replace
	SET_COMMAND_MODE.  Diagnostic ambiguous command as soon as seen.
	However, be forgiving if command has merely been repeated.

	preset_group to group_option and preset_mode to mode_option.

	* create.c, incremen.c, list.c, tar.c, commun.h: Have
	after_date_option be a Boolean instead of a three-valued flag.
	Rename threshold_time to newer_mdate_option, which may be looked
	at without checking after_date_option first, as threshold_time

	--ignore-failed-read.
	Reported by Ralph Schleicher.

	* create.c (deal_with_sparse): Chain the last partial zero block

	already usable as a flag for the same thing.

1997-03-21  François Pinard  <pinard@iro.umontreal.ca>

	* names.c (name_gather): Do not declare static variables which
	do not need to be.  Have allocated_length represent the full

	(addname): Similar cleanups.

1997-03-20  François Pinard  <pinard@iro.umontreal.ca>

	* compare.c: Always call report_difference when there is a
	problem, so the exit status will be set in all cases.  Build the
	message string if necessary, so avoiding stdargs/varargs.
	(report_difference): If NULL argument, just set the exit status
	without reporting a message.  Move out the word `differs'
	in all callers, do not insert into an English message.
	(read_and_process): Return void, as the int result is never used.
	Assume processors returns nonzero for success and zero for
	failure, instead of 0 for success and -1 for error.
	(process_rawdata, process_dumpdir): Adjusted.

	* compare.c: Remove different as a global variable, it is useless.
	(diff_sparse_files): Make different a local variable, reinitialise
	it on each call.  Otherwise, after any error elsewhere, all sparse
	files were always and falsely reported as erroneous.
	Reported by James E. Carpenter and Tim Towers.

	whenever checksums do not match.
	Reported by Marc Boucher and Marty Leisner.

	* incremen.c (get_directory_contents): Use stat_data instead of
	current_header for checking normal files.  Otherwise, new or
	modified files in old directories were not dumped, that is, if a
	directory was older than the listed entry, it was skipped
	completely without checking the contained files.
	Reported by David Johnson, John David Anglin and Wolfram Wagner.

	* buffer.c (open_archive): When updating the archive, initialize
	the access variable with reading mode, not update mode.
	Reported by Andreas Schwab.

	so deleting a file after a big one will not destroying the archive.
	Reported by Akiko Matsushita, Andreas Schwab, Eric Backus, Jeff
	Siegel, Saul Lubkin, Stuart Kemp and Yasushi Suzudo.

	(get_directory_contents): Renamed from get_dir_contents.
	* common.h: Adjusted.

	* all: Cleanup around local variables, renaming them more
	appropriately, using initializers when natural, and moving them
	closer to the blocks where they are used.

	A bit of reorganisation in the sources:
	* common.h: New file, for holding all GNU tar specific definitions,
	which were previously held in tar.h.
	* tar.h: Now limited to the archive format description only.

	* all: Add a FIXME comment everywhere errno is modified by tar.

	* buffer.c (new_volume): Return nonzero/zero for success/failure,
	instead of zero/negative.  Callers adjusted.  Use xstrdup on
	file name given by user with the answer "n", so avoiding the
	apparently useless allocation of one extra byte.  Avoid using p.

	* buffer.c: Add DEBUG_FORK conditional code.
	Reported by Thomas König and Ulrich Drepper.

	* misc.c (maybe_backup_file): In the renaming message, say that
	the previous file is being renamed, not the newly extracted one.

	* buffer.c (backspace_output): Change return type to void, since
	returned values were never used.
	* update.c (move_arch): Idem.

	Matt Power, Warren Dodge and Wolfram Gloger.

	* system.h (N_): Define marking macro for delayed translations.
	* rmt.c: Use N_ instead of _ for returned strings.  It does not

1996-01-02  François Pinard  <pinard@iro.umontreal.ca>

1995-12-19  François Pinard  <pinard@iro.umontreal.ca>

	* buffer.c: Have real_s_name able to hold PATH_MAX characters,
	not only NAME_FIELD_SIZE.  It was breaking --multi-volume
	--listed-incremental when backing up long file names.
	Many symptoms really: a screwed-up date on the incremental data
	file, dumping incremental which should not have been, etc.
	* (flush_read): Avoid altering save_name pointer value, use
	cursor instead.  Also avoid the optimization of cleaning each
	save_name only once per flush_read if it did not change: it
	was using `save_name = real_s_name;', and since save_name may
	be freed at any time, this is/was really running after trouble.

	* create.c, diffarch.c, extract.c, gnu.c, list.c, rtapelib.c,
	tar.c: Drop register specifications, useless in GNU's tar, as
	tar does not use longjmp, and GNU C has -O automagically set.

	* extract.c (extract_archive): Inhibit creation of links, special
	devices, directories, etc., when --to-stdout option is being used.
	Reported by Donald B Gordon, Gerben Wierda, Greg Chung, Norbert

	Reported by Jonathan Kamens.

1995-11-23  François Pinard  <pinard@iro.umontreal.ca>

	* tar.c (name_scan, name_match): Avoid labels and gotos.

	* tar.c (usage): Replace `modificators' by `modifiers'.
	Reported by Alan Modra.

	* extract.c (set_mode, set_stat): New functions, from

	appropriately with function calls.  Ensure mode bits are properly
	set in all circumstances.  This may imply calling set_mode twice.
	Reported by Piercarlo Grandi and Tim Magill.

	* extract.c: Save the whole stat information in saved
	directory information, instead of parts of it, all mistyped.
	(restore_saved_dir_info): Free information as we consume it.

	* tar.c: Rename --modification-time by --touch, and provide a
	warning for the old option.

1995-06-24  François Pinard  <pinard@iro.umontreal.ca>

	* list.c (decode_header): At extraction time, use the stored
	uid if uname is unknown in this system, and use the stored gid if
	gname is unknown in this system, instead.  This solves a long
	lasting bug by which restored files were all owned by root, using
	an incomplete /etc/passwd or /etc/group file.
	* names.c: Rename finduname to uid_to_uname and findgname to
	gid_to_gname, exchanging the order of arguments.  Use uid_t and
	gid_t instead of int's.  Use empty strings in cached_[ug]name for
	marking there is no valid cached translation, instead of using
	magic values for cached_[ug]id.  Rename finduid to uname_to_uid
	and findgid to gname_to_gid, adding a second argument to store the
	result if found, and returning a success/failure indication, not
	anymore assuming the current [ug]id by default.
	* tar.h, create.c, list.c: Adjust prototypes and callers.

	Reported by Anders Andersson, Bernard Derval, Brian Perkins,
	Charles Fu, Daniel Trinkle, Ian Jackson, Johannes Helander,
	Michael Lin, Richard Sims, Robert E. Brown, Tim P. Starrin and
	Torkel Hasle.

	* tar.h, create.c, list.c, names.c, tar.c:
	Implement --numeric-owner, to replace the NONAMES define.  Then,
	ensure some reasonable values to magic and linkflags if POSIX.
	Reported by Benedikt Stockebrand, Ian Jackson and Stephen Gildea.

	* buffer.c: Delete save_block function, as well as
	saved_block_pointer and saved_block variables.  Blocks were
	carefully saved indeed, but never consulted after the fact.
	* tar.h: Delete save_block prototype.
	* *.c: Delete all usages of save_block.

	* rmt.c: Add static to variable declarations.

	* *.[hc]: Rename saverec to save_block, findrec to
	find_next_block, and userec to set_next_block_after.
	Replace endofrecs by available_space_after which does the space
	computation instead of returning the end pointer, adjust and
	simplify all callers, by using variable data_block systematically.
	Also, rename union block field charptr to buffer.

1995-06-22  François Pinard  <pinard@iro.umontreal.ca>

	* *.[hc]: Exchange "record" and "block" almost everywhere and
	whenever appropriate, to follow the terminology used in
	P1003.1-1990, and so removing a lot of confusion in sources.

	* tar.h: Prefer naming constants and fields per P1003-1.1990 as
	far as possible.  Rename those remaining LF_xxx to GNUTYPE_xxx.
	* *.c: Adjusted accordingly.

	* tar.h: Clean up the header structure.  Make very clear what is
	specified by POSIX, and what is GNU format, and what is extended
	header for sparse files.  Use xxx_FIELD_SIZE instead of NAMSIZ,
	TUNMLEN and TGNMLEN.  Dismangle some other names, on the way...
	* *.c: Adjusted accordingly.

	* tar.h: Do not declare baserec, declare current_block_ordinal.
	* buffer.c (current_block_ordinal): New function.
	Rename baserec to record_start_block, and make it static.
	* list.c: Use current_block_ordinal, avoid baserec computations.
	* buffer.c, list.c: Get rid of saved_recno and annofile.

	* buffer.c, diffarch.c: Move no_op and wantbytes from
	buffer.c to diffarch.c.  Correct prototypes so first arg is long.
	* tar.h: Do not declare no_op nor wantbytes, anymore.

	current_block and record_end.

	* tar.h, buffer.c: Move ar_reading from tar.h to buffer.c,
	renaming it to reading_archive.
	* diffarch.c: Add temporary extern declaration for
	reading_archive.

	* buffer.c, create.c, diffarch.c, extract.c, gnu.c,
	list.c, names.c, rmt.c, rmt.h, rtapelib.c,
	tar.c, update.c: Replace many #ifdef's by #if's, and
	#ifndef's by #if !'s.

	* buffer.c (redirect): New name for dupto.  Callers changed.

	* create.c (dump_file), extract.c (extract_archive,
	extract_sparse_file), tar.h: Remove crumb about ending_blanks
	and end_nulls.

	* Makefile.in (all): Do not prepare genfile by default, as it
	is only needed for checking.

	* tar.c (decode_options): Diagnose lacking arguments to old
	options.
	Reported by Aage Robeck, Alan Cox, Benny Holmgren, Bruno Haible,
	Daniel Quinlan, Michael Schmidt, Richard J. Kettlewell and Robert

	those are already declared in rmt.h.

1995-06-18  François Pinard  <pinard@iro.umontreal.ca>

	Replace ck_close by xclose in all modules.
	* port.c: Remove ck_close.

	* port.c: Remove ck_malloc, because xmalloc can be used
	instead, now that it protects against malloc(0) returning NULL.
	* gnu.c (gnu_restore), list.c (read_header): Replace
	ck_malloc with xmalloc.  In gnu_restore, remove skipping code in
	case of failed allocation, because tar already aborted in xmalloc.
	* tar.h: Delete ck_malloc declaration.

	* port.c: Remove mknod, link, chown and geteuid, which
	normally exist on Unix.  To be reinserted later, as needed.

	* port.c: Deleted.
	* Makefile.in: Adjusted.

	* misc.c (un_quote_string): If `\' ends a string to unquote,
	just pass it undisturbed.
	From Robert Lipe.

	* system.h: Replace many #ifdef by #if, #ifndef by #if !.

	* create.c (dump_file), gnu.c (get_dir_contents): Cast
	(int) explicitely for test.

	* Makefile.in ($(OBJECTS)): Depend on ../intl/libgettext.h
	instead of ../intl/libintl.h, which does not always exist.

	* genfile.c: Define EXIT_SUCCESS and EXIT_FAILURE if not.
	* tar.c (main): Use TAREXIT_SUCCESS instead of EXIT_SUCCESS.

	* tar.h: Use off_t instead of long for the second argument in
	__rmt_lseek declaration.
	* system.h: Remove typedef of off_t, because AC_TYPE_OFF_T
	takes care of it now.
	Reported by Coranth Gryphon, Jim Blandy and Thomas Krebs.

1995-06-15  François Pinard  <pinard@iro.umontreal.ca>

	setlocale to void independently of ENABLE_NLS.
	Reported by Ulrich Drepper.

1995-06-10  François Pinard  <pinard@iro.umontreal.ca>

	* tar.c (long_options): Use no_argument and require_argument,
	instead of constants.  Have long option names translated to short
	options whenever possible, rather than setting flags directly:
	easing option management is worth a few extra nanoseconds.

	* tar.c (long_options): Add --gunzip as meaning -z.
	Reported by Bruno Haible.

1995-06-07  François Pinard  <pinard@iro.umontreal.ca>

	* Makefile.in: Use subdir and distdir.

	* Makefile.in (INCLUDES): Use ../intl in compilations,
	taking care of the fact libintl.h might have been symlinked there.

	* tar.h: Delete COMMAND_VERSION.

	Reported by Marty Leisner.

1995-06-04  François Pinard  <pinard@iro.umontreal.ca>

	* Makefile.in (check): New goal.

	* tar.c (name_match): Use %s for printing directory, not %d.
	Reported by Marty Leisner.

	* tar.c (name_gather, addname): chdir_name receives string

	into structures, so, use xstrdup for the time being.
	Reported by Michael Holmes.

	* tar.c (name_next, name_from_list): Abort when chdir fails.
	Reported by Ian Jackson and Marty Leisner.

1995-05-28  François Pinard  <pinard@iro.umontreal.ca>

	instead of long, so it is the same as in rmt.c.
	Reported by Chris Arthur.

	to ar_block at open_archive time, for when -M used, just before
	calling free.
	Reported by Bruno Haible, Clinton Carr, Hernan Prieto Schmidt,
	Kevin Dalley, Loren J. Rittle and Marty Leisner.

	* rmt.c: Replace SSIZE by STRING_SIZE, avoiding a conflict
	with some header files.
	Reported by Kaveh R. Ghazi and William Bader.

	* tar.c: Use DEVICE_PREFIX instead of DEVICE_PREXIX, and
	WITH_REGEX instead of WITH_REGEC.
	Reported by Bruno Haible.

1995-05-16  François Pinard  <pinard@iro.umontreal.ca>

	pipe, instead of the useful one, prior to processing.
	Reported by Charles Lopes and Minh Tran-Le.

1995-02-22  François Pinard  <pinard@iro.umontreal.ca>

	* Makefile.in: Use top_srcdir.

1995-02-11  François Pinard  <pinard@iro.umontreal.ca>

	* gnu.c (is_dot_or_dotdot): Through NFS, readdir might deliver
	empty filenames under old Solaris 2.4, causing endless loops in
	tar.  As a workaround, avoid `' as done already for `.' and `..'.
	Reported by Jan Carlson.

1995-02-05  François Pinard  <pinard@iro.umontreal.ca>

	return EACCES instead of EEXIST on mkdir.
	Reported by Jeffrey Goldberg.

	* tar.c (usage) [MSDOS]: Do not tell about -N and related.
	(decode_options) [MSDOS]: Be blind to -N and related.
	Reported by Jeffrey Goldberg.

	* rmt.h (_remdev): A filename is not remote if the colon is
	preceeded by a slash, to take care of `/:/' which is a shorthand
	for `/.../<CELL-NAME>/fs' on OSF's Distributing Computing
	Environment (DCE) and Distributed File System (DFS).
	Reported by Travis L. Priest.

1995-01-03  François Pinard  <pinard@iro.umontreal.ca>

	* tar.c (decode_options): Renamed from options.  Convert
	oldish-style non-dashed options to modern writing before
	performing option decoding.  Diagnose when modern options are met
	before old style options are fully converted.  This allows
	mixing of option styles on a single call.  Avoid getoldopt and
	use getopt_long instead.
	* getoldopt.c: Deleted.
	* tar.h: Prototype deleted.
	* Makefile.in: Adjusted.
	Reported by Bruno Haible, Les Mikesell, Patrick Timmons and Saul
	Lubkin.

	* rmt.c: Include "system.h", and simplify accordingly.
	* rtapelib.c: Include "system.h", and simplify accordingly.
	* rmt.h: Simplify according to the inclusion of "system.h".

	* system.h: Include conditionnaly <sys/gentape.h>,
	<sys/tape.h>, <sys/mtio.h>, <sys/ioctl.h> and <sys/io/trioctl.h>.
	* buffer.c, diffarch.c, rmt.c, rtapelib.c,
	update.c: Simplify accordingly.

	* system.h: If it exists, include <sys/ioccom.h> prior to
	<sys/mtio.h>, to account for problems when GNU libc 1.0x is
	installed over SunOS 4.1.3: GNU libc does not provide sys/mtio.h,
	so it is taken from Sun header files which use things like _IOW,
	which GNU libc despises, sys/ioccom.h then provides definitions.
	Reported by Joseph E. Sacco.

1994-12-27  François Pinard  <pinard@iro.umontreal.ca>

1994-12-03  François Pinard  <pinard@iro.umontreal.ca>

	* Prerelease 1.11.6.

	* rmt.c: Adjust for localization, by including <locale.h> and
	<libintl.h>, by defining _(), by defining and calling setlocale,
	and by defining and initializing program_name.
	* Makefile.in: Use locale.o and libtar.a with rmt.

	* Makefile.in: Ensure INSTALL_DATA is defined.

	* Makefile.in, tar.h, tar.c:

	extract.c, getoldopt.c, gnu.c, list.c,
	mangle.c, port.c, rtapelib.c, tar.c,
	update.c: Use _ macro over all localizable strings.

	Ryutaro Susukita.

1994-10-09  François Pinard  <pinard@iro.umontreal.ca>

1994-10-04  François Pinard  <pinard@iro.umontreal.ca>

	* diffarch.c (fill_in_sparse_array): Add a cast for Pyramid's
	dumb compiler.  Later remove the cast and compare to 0 instead.
	* extract.c (extract_archive): Idem.
	Reported by Karl Vogel and Kaveh R. Ghazi.

1994-09-27  François Pinard  <pinard@iro.umontreal.ca>

1994-09-26  François Pinard  <pinard@iro.umontreal.ca>

	* tar.c (name_next, name_match): Abort tar if directory cannot
	be changed, instead of going on.  This is not an innocuous error.
	Reported by Marty Leisner.

1994-09-15  François Pinard  <pinard@iro.umontreal.ca>

	* rtapelib.c: Include "rmt.h" only once <sys/types.h> has been
	included, because off_t might not be defined otherwise.
	Reported by James W. McKelvey, John L. Chmielewski, Karl
	Vogel, Kaveh R. Ghazi an and Jim Meyering and Tilman Schmidt.

1994-09-14  François Pinard  <pinard@iro.umontreal.ca>

	* Makefile.in: Cleanup...
	(DISTFILES): Distribute TAGS.
	(ansi2knr): Use $(LIBS).
	(TAGS): Make TAGS in $(srcdir) only.
	(distclean): Do not remove TAGS.
	(realclean): Remove TAGS.
	(Makefile): Have ./config.status create this Makefile only.

1994-09-13  François Pinard  <pinard@iro.umontreal.ca>

	* buffer.c: Remove the presetting of stdlis, because stdout is
	not a constant in GNU libc.
	Reported by Joseph E. Sacco and Thomas Bushnell n/BSG.

	* buffer.c (new_volume): Pass an otherwise unused argument to
	wait, do not use NULL.
	Reported by Thomas Bushnell n/BSG.

1994-09-05  François Pinard  <pinard@iro.umontreal.ca>

	* Makefile.in (TAGS): Remove -t on etags call.  It has been
	the default behavior for a few releases of Emacs and it seems that
	option -t is now disappearing (from Emacs 19.25, at least).
	Reported by Goeran Uddeborg.

1994-09-02  François Pinard  <pinard@iro.umontreal.ca>

	* gnu.c (get_dir_contents): Do not set dp->allnew if dp is not
	set itself.
	Reported by Piercarlo Grandi.

	* extract.c (extract_archive): Issue diagnostic or verbose
	messages to msg_file, instead of stdout.
	Reported by Piercarlo Grandi.

1994-08-23  François Pinard  <pinard@iro.umontreal.ca>

	* tar.h: Do not declare alloca if already defined, so HP's
	+Olibcalls compiler option works.
	Reported by John David Anglin.

	* rtapelib.c (__rmt_open): Use REMOTE_SHELL only if defined.
	Otherwise, if the command argument has been specified and
	REMOTE_SHELL is not defined, immediately return an error.
	Reported by Bruno Haible, Kaveh R. Ghazi, Marty Leisner,
	Torkel Hasle and William Bader.

	Because --rsh-command may always be given, even if no remote shell
	was found at configure time, remote capabilities are always
	compiled.  This also solve other problems related to RTAPELIB.
	* Makefile.in: Always compile $Urtapelib.o.
	* buffer.c (child_open): Always test _remdev, do not depend
	anymore on HAVE_RTAPELIB.
	* rmt.h [!HAVE_RTAPELIB]: Remove some code.
	Reported by Andreas Schwab and Vic Abell.

	* rtapelib.c: Remove unused COMPAT (mis)feature.  Remove most
	length limitations for remote host name, remote user name and
	remote device name.  Duplicate path, and free it in all cases.
	* (_rmt_rexec): The `user' parameter may never by the empty
	string.  Remove code for that case.

1994-08-22  François Pinard  <pinard@iro.umontreal.ca>

	Little cleanup in installation:
	* Makefile.in: Remove rule for ../lib/libtar.a.

	* tar.h: Replace W* definitions.  Adapted from make 3.71.
	* buffer.c (close_archive): Replace WIFCOREDUMPED by
	WCOREDUMP.  Previous WIFSIGNALED definition was excluding SIGSTOP,
	new definition do not exclude it anymore.  We'll see.
	Reported by Demizu Noritoshi, Greg Black, Kaveh R. Ghazi,
	Robert E. Brown and Russ Evans.

1994-08-20  François Pinard  <pinard@iro.umontreal.ca>

	This might (?) solve the dirent problems on NeXT's and Apollo's:
	* tar.h: Change includes and defines from older AC_DIR_HEADER
	style to newer and clearer AC_HEADER_DIRENT style.
	* create.c, gnu.c: Replace NLENGTH by NAMLEN.
	Reported by Drew Trieger, Hugh Secker-Walker, James W. McKelvey,
	Robert E. Brown and Thomas Krebs.

1994-08-17  François Pinard  <pinard@iro.umontreal.ca>

	Remove some shadowings.
	* update.c (update_archive): Rename head_standard to unused.
	* buffer.c (open_archive): Rename head to label.
	(fl_read): Rename head to cursor.

	* gnu.c (dirent_cmp): Use (char *const *), not (const char **)
	for not loosing the const specifier while casting.

	* create.c (deal_with_sparse): Remove unused argument.
	* create.c (dump_file): Caller changed.
	Reported by Greg Black.

	* Makefile.in: Avoid $U in defining RTAPELIB.  Remove both
	rtapelib.o and _urtapelib.o explicit rules, not needed anymore.
	* rmt.h, buffer.c [HAVE_RTAPELIB]: Instead of !NO_REMOTE.
	Reported by Andreas Schwab.

	* Makefile.in: Correct a typo in $Ubuffer.o dependencies.
	Reported by Andreas Schwab.

	* rtapelib.c (__rmt_ioctl): Compile the MTIOCGET case only if
	this symbol is defined.  This also solves a missing mt_type field
	on NS32016 running SysVr2.2.
	Reported by Greg Black.

	* rtapelib.c (__rmt_ioctl) : Conditionnalize only the MTIOCTOP
	case, not the whole routine, with the MTIOCTOP symbol.  In case of
	unrecognized operation, return EOPNOTSUPP instead of EINVAL.
	* rmt.h: Always provide a prototype for __rmt_ioctl.  Delete
	the RMTIOCTL machinery.

1994-08-16  François Pinard  <pinard@iro.umontreal.ca>

	* rmt.c, buffer.c: Use a more uniform way of including
	<sys/mtio.h> or its alternates.
	Reported by Daniel R. Guilderson and Kaveh R. Ghazi.

	* Makefile.in: Split rule for $Urtapelib.o into one rule for
	rtapelib.o and one rule for _rtapelib.o, taking care of the fact
	that rtapelib.c is in $(srcdir) while _rtapelib.c is in current
	directory.
	Reported by Andreas Schwab, Kaveh R. Ghazi, Minh Tran-Le and
	Per Foreby.

	* rmt.c (string_error): Correct DEBUG2 into DEBUG1, and strint
	into string.
	Reported by Anders Andersson, Bruno Haible, Thomas Krebs and
	Thomas König.

	* Makefile.in: Add $U's to rtapelib and rmt specific rules.
	Reported by Thomas König.

1994-08-15  François Pinard  <pinard@iro.umontreal.ca>

	* Prerelease 1.11.4.

	* rmt.c (numeric_error): Renamed from error.
	(string_error): New, to replace ERROR ((...)), unavailable in rmt.c.

	* rmt.c (checkbuf): Do not accept, nor return record.  Use the
	global instead.  This will get rid of useless shadowings.

	* rmt.h: Give prototypes for __rmt_* routines.
	* rtapelib.c: Include "rmt.h".
	* update.c (move_arch): Cast last rmtioctl argument to char *.

	Check if WIFSTOPPED is defined, to decide if defining others WIF*.
	Reported by Bruno Haible.

1994-08-11  François Pinard  <pinard@iro.umontreal.ca>

	* extract.c (extract_archive) [O_CTG]: Declare longname variable.
	Initialize it as NULL.  This dirty kludge will allow the module to
	compile on Masscomp's, for the time being.
	Reported by Ben A. Mesander.

	* tar.h, rtapelib.c: Declare strstr if we replaced it.
	Reported by Ben A. Mesander, Christian T. Dum and Kaveh R. Ghazi.

1994-08-10  François Pinard  <pinard@iro.umontreal.ca>

	* create.c (dump_file): Do not test only for hpux, but also
	for __hpux.  I added __hpux__ too, as done in tar.h.
	Reported by Richard Lloyd.

	* tar.h: Do not include <sys/mknod.h> anymore for HP-UX from
	HP-UX 8 and after, for which definitions are in <sys/sysmacros.h>,
	and reorganize the tests in this area.
	Reported by Christian T. Dum, Dimitris Fousekis, Kimmy Posey,
	Michael Maass, Richard Lloyd and Thomas König.

1994-08-09  François Pinard  <pinard@iro.umontreal.ca>

	These changes for const-cleaning gnu.c and tar.c:
	* tar.c (read_name_from_file): Work directly on global
	variables instead of accepting parameters.  Return success or
	failure as an int instead of the relocated name_buffer.
	(name_next): Caller changed, internal clean-up of the function.
	Remove trailing slashes on the command call too, not only when
	reading from a file through -T option.
	* gnu.c: Add const to name and dir_text in struct dirname.
	Reported by Ben A. Mesander, Bruno Haible, Christian T. Dum,
	Dean Gaudet, James W. McKelvey, Richard Lloyd and Robert E. Brown.

1994-08-08  François Pinard  <pinard@iro.umontreal.ca>

	* tar.c (name_next, name_gather, addname): Use strcmp for
	checking for "-C", instead of decomposed tests, just for clarity.

	* Makefile.in (RSH): Define from configuration.
	(rtapelib.o): Define REMOTE_SHELL from $(RSH) while compiling.
	* rtapelib.c (__rmt_open): If command not given, use
	REMOTE_SHELL, instead of cascading tries of filenames.
	Reported by Bruno Haible.

	* tar.c: Include <fnmatch.h> if FNM_LEADING_DIR is not
	defined, instead of checking for FNM_PATHNAME, because some
	<unistd.h> define the later without defining the former.
	Reported by Thomas König.

	* create.c (dump_file): Cast alloca results, for those
	compilers not processing void * properly.
	Reported by Kaveh R. Ghazi.

	* Makefile.in: Get prefix and exec_prefix from configure.
	Reported by Andreas Schwab, Christian T. Dum and Dean Gaudet.

	* src/port.c: Delete mkdir (and rmdir), rename, strstr and
	ftruncate replacements.

	Reported by Bruno Haible (for mkdir and rename).

1994-08-05  François Pinard  <pinard@iro.umontreal.ca>

	* tar.h: Replace msg_file by stdlis.
	* buffer.c, gnu.c, list.c, diffarch.c: Idem.

	* tar.c (main): Print version on stdout, not stderr.

	* tar.h: Unconditionnaly insert the pad.  Why play the game of
	forcing the compiler to do it for us?  (Hum!  I'm not so sure.)
	Reported by Bruno Haible.

	* list.c (read_header): Initialize signed_sum to 0.  Use this
	opportunity for slightly reorganizing the code around.
	Reported by Anders Andersson, Andrey A. Chernov, Bruno Haible
	and Chris Ransom.

	* tar.c: Declare name_buffer_length as size_t instead of int.
	Reported by Andreas Schwab, J.T. Conklin, Kaveh R. Ghazi and
	Robert E. Brown.

	* rmt.h: Have the NO_REMOTE case be a particular case of the
	other, for rmtopen and rmtcreat were not transmitting the proper
	number of parameters to open and creat (since 26 July 1994).
	Reported by Andreas Schwab.

	* extract.c (extract_archive): Delay changing owner to after
	doing utime, for keeping long enough the permission of utime'ing.
	(extract_archive, restore_saved_dir_info): Idem for directories.
	Reported by Jonathan I. Kamens.

	* tar.h: Change malloc_dbg to dmalloc, mutatis mutandis.

	* tar.h: Undefine many macros if stat macros found to be
	broken.  Define mkfifo only if configure did not find it.
	Include <sys/param.h> if not _POSIX_SOURCE, then <unistd.h> if
	we have it, than "pathmax.h".  Move _POSIX_VERSION dependent
	code further down.  Do not declare getcwd if we do not have it.
	* tar.c: Do not include <unistd.h>, now in "tar.h".
	Reported by Bernard Chen, Jean-Michel Soenen, John L.
	Chmielewski and Kaveh R. Ghazi.

	* tar.h: Define DEV_BSIZE, ST_BLKSIZE and ST_NBLOCKS,
	borrowing this code from both fileutils-3.9's "lib/system.h" and
	textutils-1.9's "system.h".
	* create.c (dump_file): Straighten the test for sparseness,
	which was requiring one block too much, most probably for trying
	to get around DEV_BSIZE/st_blksize confusion.  Use ST_NBLOCKS,
	instead of computing a variable block_size and doing specific
	tests for HP-UX or Linux.  Also rewrite the test so it works
	when ST_NBLOCKS is unsigned.
	Reported by Bruno Haible, Dean Gaudet, Dick Streefland, Harald
	König, Jim Meyering, Kai Petzke, Kaveh R. Ghazi and Torkel Hasle.

1994-08-04  François Pinard  <pinard@iro.umontreal.ca>

	* tar.c: Do not include <unistd.h> if we do not have it.

	Ghazi and Robert E. Brown.

1994-08-02  François Pinard  <pinard@iro.umontreal.ca>

	* Prerelease 1.11.3.

	* tar.c (assign_string): New routines.
	* create.c (dump_file, start_header), extract.c
	(extract_archive), list.c (list_archive, read_header),
	buffer.c (open_archive), diffarch.c (diff_archive): Use
	assign_string for setting these variables to a string value or
	NULL.
	* buffer.c (open_archive): Sets current_file_name,
	current_link_name and save_name to NULL.
	(close_archive): Free each of them if not NULL.
	(fl_write): Take a copy of save_name into cursor, and advance the
	cursor instead, because save_name should stay free-able.
	Reported by Dave Gentzel, Harald Anlauf, Mark Clements, Robert
	Weissenfels, Ronald van Loon, Tsutomu Yamada and Vic Abell.

	* extract.c (extract_archive): Use xstrdup, for clarity.
	* gnu.c (add_dir): Idem.

	* list.c (print_header): Correct a little bug by which
	non-symbolic links were not printed properly quoted.

	* diffarch.c (diff_archive): Allocate tmpbuf to the proper
	size.  NAMSIZ + 2 is not necessarily enough.

1994-08-01  François Pinard  <pinard@iro.umontreal.ca>

	* tar.h: Refresh str*/mem* configured declarations.  Among
	other things, this will solve previously missing #undef's.
	* rmt.h: Revise strchr configured declaration.
	* *.c: Replace bzero by memset, bcopy by memcpy, bcmp by
	memcmp, index by strchr and rindex by strrchr.
	* port.c: Delete functions bzero and bcmp, said to not exist
	on Minix.  AC_MINIX in configure.in should guarantee POSIX things.
	Reported by Drew Trieger, Hugh Secker-Walker and Vic Abell.

	* tar.h, tar.c, buffer.c, update.c: Change CMD_* to COMMAND_*.

	* buffer.c (open_archive): Use strcmp to compare archive name
	to `-', instead of doing it explicitely.  Just for clarity.

	* tar.h, tar.c, buffer.c: Replace ar_files by
	archive_name_array, n_ar_files by archive_names and ar_files_len
	by allocated_archive_names.  Replace the index cur_ar_file by
	archive_name_cursor, which is a cursor in archive_name_array.

	* tar.c (main): Move the initialization of
	archive_name_array at beginning, taken from options routine.
	Free it at end of main.
	(options): Use xrealloc instead of ck_realloc for archive_name,
	for the already saved names to be preserved.
	Reported by Per Bojsen.

	* tar.h, tar.c: Replace name_file by namefile_name.
	* tar.c: Replace n_ind by name_array, n_indused by names,
	n_indalloc by allocated_names, and n_indscan by name_index.
	Replace namef by name_file, n_argv by names_argv and n_argc by
	names_argc.
	(main): Make an initial allocation for name_array at beginning,
	moved out from name_add, free it at end of main.

	* buffer.c (close_archive): Free ar_block at end.

1994-07-30  François Pinard  <pinard@iro.umontreal.ca>

	* tar.h [WITH_MALLOC_DBG]: Include "malloc_dbg.h".

	* create.c (create_archive): Do not attempt creating a
	directory summary file if -G, since -G sets gnu_dumpfile to 0.
	Reported by Alexander Dupuy.

	* create.c (dump_file): Avoid a NULL dereference with -G when
	trying to dump an empty directory.
	* gnu.c (add_dir_name): Same thing.
	Reported by Rainer Orth.

	Correction for the improper `data differs' diagnostic given when
	the continuation of a multi-volume was compared.
	* diffarch.c (diff_archive): If multi-volume, update save_name
	and save_totsize before calling wantbytes.
	* buffer.c (wantbytes): If multi-volume, update save_sizeleft.

	* extract.c (extract_archive): Idem.
	Reported by Timothy Fossum.

1994-07-29  François Pinard  <pinard@iro.umontreal.ca>

	* create.c (dump_file): Abort if no memory for a possible
	link, remove related bogus code, and the variable nolinks.
	Reported by Andreas Schwab.

	* create.c (dump_file): Detect file sparseness correctly for
	Linux ext2 filesystem.
	Reported by Kai Petzke.

	* port.c (link) [!MSDOS]: Do not call setmode.
	Reported by Richard Deal.

	Reorganization for `tar -d' to provide a different exit status.
	* tar.h: Replace errors by exit_status.  Declare TAREXIT_*.
	* buffer.c (child_open): Exit with exit_status.
	* tar.c (main): Initialize exit_status to TAREXIT_SUCCESS, and
	exit with exit_status.
	* buffer.c, diffarch.c, gnu.c, list.c, port.c,
	rmt.c, tar.c, update.c: Replace EXIT_FAILURE by
	TAREXIT_FAILURE, and EXIT_SUCCESS by TAREXIT_SUCCESS.
	* tar.h (ERROR), create.c (dump_file): Set exit_status to
	TAREXIT_FAILURE instead of increasing errors.
	* diffarch.c (sigh, diff_sparse_files): On differences, set
	exit_status to TAREXIT_DIFFERS if nothing more serious already.
	Reported by Tilman Schmidt.

	* rmt.c: Define EXIT_FAILURE and EXIT_SUCCESS if not already.
	* rtapelib.c: Define EXIT_ON_EXEC_ERROR to 128 and use it.

1994-07-27  François Pinard  <pinard@iro.umontreal.ca>

	* diffarch.c (sigh): Increment errors, so a difference will
	yield a non-zero exit status at end.
	Reported by Nick Holloway.

	* tar.h: Rename TARERROR to WARN, then add ERROR which is similar,
	but increments the errors counter.
	* *.c: Replace all TARERROR by WARN or ERROR, deciding for each
	case.  Many errors were not reflected in exit status.

	Reported by Carl Streeter, Esa Karell, George Chyu, Ian Jackson,
	Judy Ricker, Massimo Dal Zotto, Roland McGrath, Tilman Schmidt
	and Torkel Hasle.

	* buffer.c (child_open): Exit with EXIT_FAILURE if any error.

	* rtapelib.c: Use error for reporting errors.
	(do_command): New name for command.
	(get_status): New name for status.

	* buffer.c: Remove definition of MAGIC_STAT.
	(close_archive): Do not check MAGIC_STAT for an exit value, since
	this value is never returned.

	* *.c: Use TARERROR or exit with EXIT_FAILURE, instead of various
	esoteric statuses.  Normalize using TARERROR with an exit status,
	instead of calling TARERROR with 0 first, then _exit.  On exit
	calls, use EXIT_SUCCESS instead of 0.
	* tar.c: Do not use the exit status anymore for outputting an
	error counter value.  Wrap around was creating spurious success.
	* tar.h: Remove EX_* definitions for tar exit statuses.
	Reported by Bob Mende and Torbjorn Granlund.

1994-07-26  François Pinard  <pinard@iro.umontreal.ca>

	* tar.h: Add f_rsh_command variable.

	* buffer.c (open_archive, child_open, new_volume): Pass
	f_rsh_command to rmtopen and rmtcreat calls.
	* rmt.h (rmtopen, rmtcreat): Pass a supplementary argument.
	* rtapelib.c (__rmt_open): Accept and process a command
	argument, to replace rsh.
	Reported by Jonathan I. Kamens.

	* tar.h: Instead of including <sys/file.h> with BSD42 or
	<fcntl.h> for V7, merely include <fcntl.h> if it exists,
	otherwise <sys/file.h>.
	* buffer.c, diffarch.c, extract.c, list.c,
	port.c, update.c: Do not include <fcntl.h> or
	<sys/file.h>, because they are indirectly included through
	"tar.h".

	* create.c (dump_file): Remove the BSD42 conditional.  If not
	f_sparse_files, initialize upperbound as when not BSD42.
	Reported by Alan Bawden, Claude Scarpelli, Laurent
	Sainte-Marthe, Noah Friedman, Reuben Sumner, Tom Quinn and
	William Bader.

1994-07-24  François Pinard  <pinard@iro.umontreal.ca>

	J.T. Conklin, Nelson H.F. Beebe and Tilman Schmidt.

1994-07-22  François Pinard  <pinard@iro.umontreal.ca>

	* create.c (start_header): Cast NAMSIZ to size_t before
	comparing it to strlen result.
	Reported by Mark Frost.

	* tar.c (main): Zero out label_pattern before compiling in
	regular expressions, instead of using uninitialized memory.
	Reported by Holger Teutsch.

	* tar.c [!FNM_PATHNAME]: Include fnmatch.h only if unistd.h fails
	to define this symbol.
	Reported by Alan Modra, Christian T. Dum, Eddy ?, John
	Oleynick and Richard Lloyd.

	* buffer.c, diffarch.c, rtapelib.c, update.c:
	Include <sys/io/trioctl.h> before <sys/mtio.h>, if it exists.
	Reported by Kaveh R. Ghazi.

	* tar.c (options): Use defined OPTION_* constants instead of
	anonymous numbers for long options not having a short option form.

	* rmt.h [!MTIOCTOP]: Do not define RMTIOCTL, so __rmt_ioctl
	will not be called if it has not been compiled in rtapelib.c.

	* tar.h: Add CMD_TOO_MANY.
	* tar.c (main): Use CMD_TOO_MANY, and get rid of badopt label.
	Reported by David J. MacKenzie.

	* tar.c (usage): New name for describe().  Rewritten with
	better help formatting and more logical grouping of options.

	* Makefile.in: Adjusted.

1994-07-19  François Pinard  <pinard@iro.umontreal.ca>

	* tar.h: Merge "port.h" towards the beginning of tar.h.
	Include <stdio.h> and <errno.h>, and define errno if needed.
	* *.c: Do not include "port.h" anymore after "tar.h", do not
	include <stdio.h>, <errno.h> nor <sys/types.h>.  Also move
	"tar.h" as the first file included in every module.  This
	would solve, among other things, the problem of RE_DUP_MAX
	being redefined by <limits.h>, when included after "regex.h".
	* port.h: Deleted.
	* Makefile.in: Adjusted.
	Reported by Alan Modra, Christian T. Dum, Dimitris Fousekis,
	John David Anglin, Matthew Braun, Michael Maass, Richard Lloyd
	and Stefan Skoglund.

	* create.c (dump_file): Do not cast alloca result to (char *).
	The problem reported was that alloca result was seen as int, but
	with the changes just made, alloca should be properly declared.
	Reported by Bryant Fujimoto and Michael Kubik.

1994-07-06  François Pinard  <pinard@iro.umontreal.ca>

	* create.c, extract.c [HAVE_UTIME_H]: Instead of _POSIX_VERSION,
	for choosing to include <utime.h>.
	Reported by Carl Swanson and Thomas Krebs.

1994-07-05  François Pinard  <pinard@iro.umontreal.ca>

	* tar.c: Replace DEF_AR_FILE with DEFAULT_ARCHIVE, replace
	DEFBLOCKING with DEFAULT_BLOCKING.

	* rtapelib.c: Replace "??'" by "?? '" at two places in a
	comment, so avoiding Pyramid's DC/OSx compiler to complain about
	ANSI trigraph sequences.  Even comments can trigger bugs, now!
	Reported by Mark Frost.

	* tar.h: Declare valloc.
	* buffer.c, diffarch.c: Remove declaration for valloc.

	* testpad.c: Deleted.
	* tar.h: Do not include "testpad.h" anymore.
	* Makefile.in: Delete testpad matters.

	* buffer.c (new_volume): Inside case 'n', strcpy into r then
	assign r to p, instead of strcpy'ing directly into p, for making
	the module const clean.

1994-07-03  François Pinard  <pinard@iro.umontreal.ca>

	Rename a few variables to avoid shadowing variables or functions:
	* list.c (print_header): Change name to quoted_name.
	* buffer.c (child_open): Change pipe to local_pipe.
	* extract.c (extract_archive): Change namelen to namelen_bis.
	* rtapelib.c (__rmt_open): Change system to remote.

	* tar.c (options): Add two missing arguments to getoldopt
	call, NULL is not necessarily implied on all systems.

	* list.c (print_header): Add a few missing long specification
	in formats.
	* diffarch.c (compare_chunk, diff_sparse_files): Idem.
	* port.c (msg, msg_perror): Idem.

	* tar.h: Include prototypes for all functions which call from
	one module to another.  Declare voidstar (use it everywhere
	instead of PTR).  Move in the include <sys/stat.h> from
	<port.h>, and the include of option.h from tar.c and
	getoldopt.c, waiting for a better solution for all these things.
	* port.c: Removed PTR declaration and including <sys/stat.h>.
	* getoldopt.c, tar.c: Remove including "option.h".

1994-07-02  François Pinard  <pinard@iro.umontreal.ca>

	* *: Protoized all function headers.  Added static to
	functions which can take it.  Add many const specifiers.  Remove
	unused variables.

	* port.c (xmalloc): Delete function, do not mask the true one.
	* port.c (ck_malloc): Use xmalloc, waiting for annihilation.
	* port.c (ck_realloc): Use xrealloc, waiting for annihilation.
	* *: Begin switching from ck_malloc (or even pure malloc) to
	xmalloc.  Same for ck_realloc (pure realloc) to xrealloc.
	Doing this correctly is a delicate matter, which I'll continue
	without reporting it anymore, while doing other modifications.

	* *: Replace msg and msg_perror calls by TARERROR macro calls.
	Capitalize first word of all error messages, remove ending
	punctuation or newline.  Systematically avoid contractions for
	`Cannot' and `Could not'.  Always write `WARNING:' all in capitals.
	* tar.h: Declare TARERROR as calling error().  Rename
	variable tar to program_name.
	* tar.c (main, options), buffer.c (child_open), port.c
	(msg, msg_perror), gnu.c (gnu_restore): Rename variable tar to
	program_name.
	* gnu.c (gnu_restore): Remove a spurious repetition of
	program_name in error message.

1994-07-01  François Pinard  <pinard@iro.umontreal.ca>

	* buffer.c, create.c extract.c, gnu.c, list.c,
	names.c, rmt.c, tar.c, update.c: Remove all (void)
	prefixes to function calls.  There are limits to lint clutter.

1994-06-30  François Pinard  <pinard@iro.umontreal.ca>

	* port.h: Remove definition of const.  Let configure do it.

	* tar.h, rmt.c, rtapelib.c, version.c, testpad.c: Add a block
	for including <config.h> or "config.h".  If "tar.h" was included
	everywhere, the block will only be needed there.

	* *.[ch]: Reindented to GNU standards (they were not far).
	Got rid of all `* ' left prefixes in comments and refilled them.
	There is still a lot of cosmetic changes needed everywhere.
	I will not report them any more, doing them along the way of
	other things in the future.

	* Makefile.in: New file.

	* Split distribution into a few subdirectories, for easing
	maintainance.

	* Taking over maintenance duties.

1993-08-31  David J. MacKenzie  <djm@goldman.gnu.ai.mit.edu>

	* rmt.c [M_UNIX]: Include sys/tape.h instead of sys/mtio.h.

        $(CFLAGS) last.

1993-05-22  The King  <elvis@graceland.gnu.ai.mit.edu>

	* extract.c (extract_archive, restore_saved_dir_info): Print

	* version.c: Released version 1.11.2.

	* Makefile.in (dist): Do the link differently; some of the
	files have changed filesystems which makes it more complex.

	* Makefile.in (dist, shar): Use gzip instead of compress.

	* create.c (dump_file): Test for curdev == -1, not curdev < 0.
	Some losing NFS systems give negative device numbers sometimes.
	Reported by Thorbjxrn Willoch.

	* buffer.c (new_volume): Write the global volume number to the
	volno file before running the info script, so that the script
	can look at it.

1993-03-17  Michael I Bushnell  <mib@geech.gnu.ai.mit.edu>

	* tar.c (describe, long_options): Changed --compress-block to
	--block-compress.
	(options): Fixed f_compress_block sanity check error message
	to give the correct name of the option.

1993-03-16  Michael I Bushnell  <mib@geech.gnu.ai.mit.edu>

	* extract.c (extract_archive): case LF_DIR: Do chown when
	necessary.  Don't bother jumping to set_filestat for
	f_modified; repeat the chmod code here.  Replace `break',
	deleted on 2 September 1992.

	* tar.c (describe, long_options, options): Added gzip options
	and use-compress-program option.
	* tar.h: Added new compression options.
	* buffer.c (child_open, open_archive): Use new compression options.

	* create.c (start_header): Only mask off high bits when

	order for error message.
	Reported by Bruno Haible.

	* create.c (deal_with_sparse): If the last byte was null, we
	didn't write it out.

	* gnu.c, create.c, extract.c, diffarch.c, list.c:
	Replace malloc calls with ck_malloc and realloc with ck_realloc.
	Reported by Jonathan Kamens.

	* tar.c (describe): Improve doc for -L.

	files.

	* tar.c (long_options, describe): Added new-volume-script as
	an alias for info-script.

	* extract.c (extract_archive): LF_DUMPDIR case; misplaced paren.

	* extract.c (extract_archive): extract_file case, first if,
	include space for null in namelen computation.

	* extract.c (extract_sparse_file): Use value returned by write
	to properly create error message.

	* create.c (create_archive): Don't assume we have anything to
	dump.

	* buffer.c (open_archive): Set current_file_name for the
	volume header so that verbose listings work properly.

	* Makefile.in (realclean): Added getdate.c.

	* create.c (deal_with_sparse): If exactly 26 elements in
	sparsearray, only 25 were written.
	Reported by Jim Murray.

	* create.c (deal_with_sparse): If the file ends with a zero
	block, the last byte was not written.  This is fixed in create
	rather than extract: if amidst_data is not set at EOF, put out a
	block with just the last byte of the file.
	Reported by Jim Murray.

1993-01-14  David J. MacKenzie  <djm@kropotkin.gnu.ai.mit.edu>

	* tar.c: Include fnmatch.h after port.h to make sure we get our FNM_*
	(e.g. on HPUX 8).

1992-11-24  David J. MacKenzie  <djm@goldman.gnu.ai.mit.edu>

	* tar.c (addname), gnu.c (read_dir_file) [HAVE_GETCWD]: Instead of USG.

1992-11-18  David J. MacKenzie  <djm@goldman.gnu.ai.mit.edu>

	* tar.c: Change FNM_TARPATH to FNM_LEADING_DIR to match change
	in fnmatch.[ch].

1992-10-02  David J. MacKenzie  <djm@goldman.gnu.ai.mit.edu>

	* tar.c (describe): Fix some tab alignments.

	create.c (write_long): 	Declare as void, not int, since they
	don't return a value.

	* All source files: re indented using GNU indent.

	* rtapelib.c (__rmt_read): Only read the amount left in the
	buffer; otherwise a broken rmt server (which puts too much
	data out) could overwrite past our buffer.

1992-09-17  Michael I Bushnell  <mib@geech.gnu.ai.mit.edu>

	* configure.in: Check for getpwuid and getgrgid.
	Reported by J.T. Conklin.

	* create.c: Throughout, use struct utimbuf rather than array
	of longs.
	Reported by J.T. Conklin and Michael Ellis.

	* Makefile.in (SRC3, AUX): Move alloca.c to SRC3.
	(OBJ3): Add @ALLOCA@.

	* Makefile.in (getdate.c): Look in srcdir for getdate.y.

	* buffer.c (close_archive): We can't check WTERMSIG
	meaningfully unless we already know tha WIFSIGNALED is true.
	(There is no guarantee it WTERMSIG will return zero when
	WIFSIGNALED is false.)
	* port.c (rmdir, mkdir): Check WIFSIGNALED rather than
	WTERMSIG.

	* Makefile.in (getdate.c): Use $(YACC) instead of `yacc'.

	losing archives missing it.

	* configure.in: Added tests for libraries needed on Solaris.

	* Makefile.in: added target and rule for getdate.c: getdate.y;
	some makes don't have one built in.

1992-09-14  Michael I Bushnell  <mib@geech.gnu.ai.mit.edu>

	* tar.c (options, main): Advise use of --help rather than
	+help.
	Reported by J.T. Conklin.

	* create.c (write_long): Using hstat here is a Bad Idea, and
	totally unnecessary at that.

	* list.c (read_header): Compute both signed and normal
	checksums.
	Reported by Robert E. Brown.

	* diffarch.c, buffer.c: Declare valloc as void* rather than
	char*.
	Reported by Robert E. Brown.

	* Makefile.in: Don't install info files.

	string.h's define them for us.

	* tar.c (addname): Missing braces after if.
	* gnu.c (read_dir_file): Missing braces after if.

	* names.c: Add include of <stdio.h>,

	* create.c (start_header): Set current_file_name so that
	print_header, used for verbose create, works properly.
	(dump_file): Set current_link_name when setting up symlink
	and hardlink records.
	Reported by Robert Crowe.

	* configure.in: Define BSD in the presence of /sdmach or
	/../../mach.
	Reported by Robert E. Brown.

	Define libdir instead of hardcoding /etc for installing rmt.

1992-09-10  Michael I Bushnell  <mib@geech.gnu.ai.mit.edu>

	* list.c (read_header): On second thought, that doesn't work
	either, so just store the names in malloced areas.  Sigh.

	* NEWS: New file.
	* README: Removed things that belong in NEWS; point to it.

	* list.c (read_header): current_file_name and
	current_link_name need to be set to the arrays in head rather
	than header; header is the actual read buffer and will change.

	* extract.c (extract_archive):
	* buffer.c (new_volume): `#' directives need to start in
	column 1.
	Reported by J.T. Conklin.

	* port.h: If compiling with gcc, use __builtin_alloca.

1992-09-08  Michael I Bushnell  <mib@geech.gnu.ai.mit.edu>

	* extract.c: Removed long name support from here.
	* list.c (read_header): Understand and skip longname/longlink
	headers here.  Names for current file are stored in new global
	variables.  All source files except create.c changed to refer
	to current_file_name and current_link_name instead of fields
	directly from the current header.

1992-09-03  Michael I Bushnell  <mib@geech.gnu.ai.mit.edu>

	* create.c (write_long): New function.
	(dump_file): When writing link records or symlink records, use
	new write_long function instead of mangling when the link
	target is too long.
	(start_header): Use write_long instead of mangling for long
	names.
	* extract.c (saverec): Recognize LF_LONGNAME and LF_LONGLINK.

	* mangle.c: This is now deprecated; retain extract_mangle for
	backward compatibility.

	* list.c (print_header): Prevent printing 0 when the gid or uid is

	in saved_dir_info_head.
	(restore_saved_dir_info): New function.

1992-08-31  Michael I Bushnell  <mib@geech.gnu.ai.mit.edu>

	* create.c (create_archive): If there are no names specified,
	write nothing on the archive instead of dumping ".".

	* create.c (dump_file): Implement f_atime_preserve.

	* rmt.h (_remdev): Don't require /dev/ to be in remote archive
	names; obey new force-local flag.
	* tar.c, tar.h: Implement new force-local flag.
	Reported by Roland Schemers III.

	* tar.c (describe): same-owner and same-order were confused.

	* create.c (dump_file): Check for toplevel had sense reversed.

	* buffer.c (new_archive): Don't free old_name...when these
	come from the command line, they aren't malloced, and it isn't
	important to save this trivial amount of memory.

	* tar.h: replace ar_file with ar_files, n_ar_files,
	cur_ar_files.
	* buffer.c (open_archive): multi-volume compressed archives
	never worked; give an appropriate error.  Change open of

1992-08-28  Michael I Bushnell  <mib@wookumz.gnu.ai.mit.edu>

	* list.c (decode_header), create.c (start_header), tar.h (TMAGIC):
	Undo djm's changes below; tar does not support the final
	Posix.1 format; it's bad to make it look like it does.

1992-07-19  David J. MacKenzie  <djm@nutrimat.gnu.ai.mit.edu>

	* port.h: Try to prevent redefining major.
	* port.c [minix]: Implies HAVE_BZERO.  Fix a typo.

	* create.c (create_archive): Allocate PATH_MAX instead of
	NAME_MAX for temporary buffer so we don't have to figure out
	what NAME_MAX is (portably).

1992-07-10  Michael I Bushnell  <mib@geech.gnu.ai.mit.edu>

	* gnu.c (collect_and_sort_names): write_dir_file has no argument.

1992-07-06  David J. MacKenzie  <djm@nutrimat.gnu.ai.mit.edu>

	unlink the destination instead to avoid leaving a mess.

1992-07-03  David J. MacKenzie  <djm@nutrimat.gnu.ai.mit.edu>

	* buffer.c, diffarch.c, update.c, rtapelib.c [HAVE_SYS_MTIO_H]:
	Instead of NO_MTIO.

	get_dir_contents; see djm's change of Fri Jul 26 01:12:58 1991.

1992-05-04  David J. MacKenzie  <djm@churchy.gnu.ai.mit.edu>

	* tar.h: Make comments for option names say -- instead of +.

1992-04-29  Michael I Bushnell  <mib@geech.gnu.ai.mit.edu>

	* tar.c, tar.t: Added +volno-file option.
	buffer.c (init_volume_number, closeout_volume_number): New functions.
	tar.c (main): Call new functions in the right place.

	* buffer.c (fl_write, fl_read): Mod to allow losing tape
	drives which use short counts to indicate end of tape
	correctly handle the multi-tape stuff.  The read half won't
	co-exist with f_reblock; there's no way to fix that, of
	course.

	* tar.c, tar.h: Added new option +show-omitted-dirs.
	list.c (read_and): Implemented show-omitted-dirs.
	Reported by Karl Berry.

	* tar.c, tar.h: Added new option +checkpoint.
	buffer.c (fl_read, fl_write): Implemented +checkpoint lazily.

	* create.c (dump_file): Added toplevel argument; some devices
	can be negative, so the old method was bogus.  All callers
	changed.

	* tar.c, tar.h: Added new option +ignore-failed-read.
	create.c (dump_file): Implemented +ignore-failed-read.

	* tar.c, tar.h: Added new option +remove-files to delete files
	after they are added to the archive.
	create.c (dump_file): Implemented +remove-files for
	everything but directories.  I don't think they need it.

1992-04-28  Michael I Bushnell  <mib@geech.gnu.ai.mit.edu>

	* create.c: (dump_file): save_name needs to be set equal to p,
	not something inside the header, because the header changes at
	the first buffer flush.

1992-04-24  Michael I Bushnell  <mib@geech.gnu.ai.mit.edu>

	* create.c: Djm incorrectly moved the include of port.h to
	precede the include of sys/file.h; restored.

	* tar.c (main): Cases CMD_EXTRACT and CMD_LIST: declare error
	string with const.

	* gnu.c (collect_and_sort_names): Leave if around
	write_dir_file in place.

1992-04-22  David J. MacKenzie  <djm@churchy.gnu.ai.mit.edu>

	_POSIX_VERSION]: Instead of POSIX ifdefs.

1991-12-20  Michael I Bushnell  <mib@geech.gnu.ai.mit.edu>

	* testpad.c (main): flush stderr so perror and fprintf
	cooperate right.

1991-12-18  David J. MacKenzie  <djm@wookumz.gnu.ai.mit.edu>

	* port.h [MAJOR_IN_MKDEV, MAJOR_IN_SYSMACROS]: To find where to
	get major, minor and makedev.
	* create.c, list.c, update.c: Don't check USG to include
	sys/sysmacros.h.

1991-12-12  Michael I Bushnell  <mib@geech.gnu.ai.mit.edu>

	* mangle.c (extract_mangle): Correctly null terminate name of
	link target.

1991-11-21  Michael I Bushnell  <mib@nutrimat>

	* create.c (dump_file, at start of ISREG output loop): use
	filename from header instead of real name to make sure that we
	get the mangled version and not one that is too long and
	overflows buffers.

1991-11-16  David J. MacKenzie  <djm@wookumz.gnu.ai.mit.edu>

	* tar.h: Use new criteria for STDC version of msg.

1991-11-02  David J. MacKenzie  <djm@wookumz.gnu.ai.mit.edu>

	* create.c, gnu.c, tar.c [USG]: Use DIRENT instead of NDIR to select
	between dirent.h and ndir.h.

	* port.c [FOO_MISSING]: Instead of WANT_FOO, to make sharing code
	and configure script with other utilities easier.
	[VPRINTF_MISSING, DOPRNT_MISSING]: Instead of FOO_MSG, to select
	error reporting routines.

1991-08-29  Michael I Bushnell  <mib@geech.gnu.ai.mit.edu>

	* tar.c (long_options).  Fixed info-script long option.
	Reported by Eric Norum.

1991-08-26  David J. MacKenzie  <djm@pogo.gnu.ai.mit.edu>

	* configure, Makefile.in: Only put $< in Makefiles if VPATH
	is being used, because older makes don't understand it.

1991-08-19  David J. MacKenzie  <djm@wookumz.gnu.ai.mit.edu>

	* create.c: Indent '#pragma alloca' so non-ANSI compilers
	don't choke on it.

1991-08-14  David J. MacKenzie  <djm@geech.gnu.ai.mit.edu>

	* list.c (UGSWIDTH): Increase from 11 (sort of like Unix tar) to
	18, so that with normal user and group names of <= 8 chars,
	the columns never shift in a tar -t listing.

1991-08-02  David J. MacKenzie  <djm@apple-gunkies>

	* Makefile.in (dist): Include texinfo.tex and tar.info*.
	(install): Install tar.info*.
	* configure: Set INSTALLDATA.

	* configure: Create config.status.  Remove it and Makefile if

	(tar.info): New target.

1991-07-30  David J. MacKenzie  <djm@apple-gunkies>

	* rmt.h: Clean up ifdefs.

	* makefile.pc: Fix typo.
	* port.h [__MSDOS__]: Instead of MSDOS.
	[__MSDOS__]: Define off_t.  Include io.h and not sys/param.h.
	[__TURBOC__]: Use void * and don't define const.

1991-07-26  David J. MacKenzie  <djm@bleen>

	* buffer.c: Rename `eof' to `hit_eof' to avoid conflict with an
	MSDOS function.
	* gnu.c (get_dir_contents): Return NULL, not "\0\0\0\0", on error.
	* diffarch.c (diff_archive): Open files in binary mode.
	Don't use or free a non-malloc'd return value from get_dir_contents.
	* msd_dir.c [__TURBOC__]: Include stdlib.h.
	* rmt.h: lseek returns off_t, not long.

	* tar.h, tar.c: Add +null option to make -T read
	null-terminated filenames (such as those produced by GNU find
	-print0), and disable -C option.
	This guarantees that odd filenames will get archived.
	* tar.c (read_name_from_file): New function.
	(name_next): Call it instead of fgets.
	From David J. MacKenzie.

1991-07-24  David J. MacKenzie  <djm@wookumz.gnu.ai.mit.edu>

	* create.c [_AIX]: Declare alloca.

	* buffer.c (open_archive): Check for successful open before,

1991-07-23  David J. MacKenzie  <djm@wookumz.gnu.ai.mit.edu>

	* configure: Only define BSD42 if sys/file.h exists.
	If alloca is missing and /usr/ucblib exists (SVR4), use it
	instead of -lPW.

	* gnu.c (dirent_cmp): Fix args to agree with ANSI C prototype.
	* create.c: Declare ck_realloc.
	* gnu.c, diffarch.c: Move check for symlinks to after port.h include.

1991-07-20  David J. MacKenzie  <djm@apple-gunkies>

	* msd_dir.[ch]: Use POSIX-style `struct dirent' instead of

	* port.c (ck_malloc, ck_realloc): Return PTR, not char *.
	* gnu.c, create.c, tar.c: Fix decls.

	* port.c: Don't use the preprocessor to guess missing
	functions on Unix; let configure do it.
	[WANT_GETWD] (getwd): Function removed; not needed because
	getcwd is used if needed.
	* gnu.c, tar.c [POSIX]: Use getcwd.

	* rtapelib.c: Use SIGTYPE instead of testing SIGNAL_VOID.
	Default to void (more common these days) instead of int.

	* tar.c, gnu.c, mangle.c: Remove VOIDSTAR defn.  Use PTR instead.
	* port.h: Define PTR.

	* gnu.c, tar.c [__MSDOS__ || USG]: Remove incorrect getcwd decl.
	[!POSIX]: Put correct one in port.h.

	* tar.c (describe): Print on stdout instead of stderr; it's
	not so much a usage message (since you have to ask for it
	explicitly) as on-line help, and you really need to be able to
	page it because it's more than a screen long.

	* Make #ifdefs for sys/file.h or fcntl.h, directory header,
	sys/mtio.h consistent between files.  Use NO_MTIO instead of
	tricks with USG and HAVE_MTIO and NO_RMTIOCTL.
	* Move decls of ANSI C and POSIX functions to port.h and
	use standard headers to declare them if available
	[STDC_HEADERS or POSIX].
	* Add many missing function declarations and return types.
	* Some places used __MSDOS__, some MSDOS; standardize on __MSDOS__.
	* Change S_IF macros to S_IS for POSIX.
	* port.h: Define appropriate S_IS macros if missing.
	* port.h [POSIX]: Rename macros for testing exit status to conform to
	POSIX; use the system's versions if available.
	* Use POSIX PATH_MAX and NAME_MAX instead of MAXPATHLEN and MAXNAMLEN.
	* port.h: Define PATH_MAX and NAME_MAX.
	* create.c, gnu.c, tar.c: Use ck_malloc and free instead of
	auto arrays of size PATH_MAX or NAME_MAX, since with pathconf
	they might not be constants.
	* Move all definitions of O_* to port.h to reduce redundancy.
	* Make all source files that now need to include port.h do so.
	* port.c: Remove #undefs of WANT_* so you can use -DWANT_*
	when compiling, instead of having to edit port.c.
	[WANT_DUMB_GET_DATE] (get_date): Function removed.
	Even systems without bison can get bison output and compile it.
	[WANT_STRING] (index, rindex, bcopy, bzero, bcmp): Functions
	removed; the translation is now done by macros in port.h.
	* wildmat.c (wildmat): Use POSIX.2 '!' instead of '^' to negate
	character classes.

	* testpad.c (main): Return type void.

	* port.c [WANT_STRING]: Don't include memory.h if NO_MEMORY_H.

	* Most files: Refer to GPL version 2.
	* COPYING: Use version 2.

	* port.c [__TURBOC__] (utime): New function.

	* xmalloc: New function (just calls ck_malloc), for alloca.c
	and bison.simple (in getdate.y output).

	* Makefile.in (AUX): Include alloca.c and tcexparg.c, a
	command line globber for Turbo C.

1991-07-08  David J. MacKenzie  <djm@geech.gnu.ai.mit.edu>

	* testpad.c: Open and write to testpad.h instead of stdout,
	because some MS-DOS makes (Borland's at least) can't do
	redirection in commands.
	* Makefile.in: Don't redirect testpad output.

1991-07-08  Michael I Bushnell  <mib@churchy.gnu.ai.mit.edu>

	* buffer.c (fl_read): Missing \n in printf.

1991-07-08  David J. MacKenzie  <djm@geech.gnu.ai.mit.edu>

	unused variables.

	* tar.c (options): Cast get_date arg to VOIDSTAR instead of
	`struct timeb *', since on some non-BSD systems the latter is
	undefined.

1991-07-06  David J. MacKenzie  <djm@geech.gnu.ai.mit.edu>

	* Replace Makefile with configure, Makefile.in, and makefile.pc.
	Update README with current compilation instructions.

	* testpad.c (main): Avoid warning from some compilers on array
	address.

	even if BSD42 is also.

	* Makefile: Replace DESTDIR with bindir.

	Reported by David Taylor.

	* Makefile: Comment describing presence of USE_REXEC.

	* extract.c (extract_archive, case LF_SPARSE): zero check for
	last element on numbytes needs to look at value after
	converted from octal.

	* port.c [HAVE_STRSTR]: Check it, instead of always demanding strstr.
	Makefile: Comment describing presence of HAVE_STRSTR option.

	it.
	* tar.c: Undo Noah's changes.

1991-04-01  Noah Friedman  <friedman@wookumz.gnu.ai.mit.edu>

        (This ought to be temporary until things are fixed properly. )

1991-03-23  Noah Friedman  <friedman@wookumz.gnu.ai.mit.edu>

	* Makefile: added default flags and options for compiling under
	hpux.

	* Added files alloca.c and xmalloc.c.

1991-03-23  Michael I Bushnell  <mib@geech.gnu.ai.mit.edu>

	* port.c [HPUX]: Define WANT_VALLOC.

1991-03-15  David J. MacKenzie  <djm@geech.ai.mit.edu>

	* rtape_lib.c [USG && !HAVE_MTIO]: Define NO_RMTIOCTL automatically.
	(_rmt_rexec): Temporarily re-open stdin and stdout to
	/dev/tty, to guarantee that rexec() can prompt and read the
	login name and password from the user.
	* Makefile: Mention -DUSE_REXEC.
	Reported by Pascal Meheut.

1991-03-08  Michael I Bushnell  <mib@wookumz.ai.mit.edu>

	* tar.h, Makefile [HAVE_SIZE_T]:  Might be useful for some people.

	* gnu.c: lstat->stat define where appropriate

	* buffer.c (fl_write): keep track of amount written for +totals.
	* tar.c, tar.h: set flag f_totals from +totals option.
	* tar.h (f_totals, tot_written): new variables.
	* tar.c (main): print total written with CMD_CREATE.

	* tar.c (main): return appropriate exit status

1991-01-17  David J. MacKenzie  <djm@apple-gunkies>

	* port.c: Remove a spurious `+' between functions (a remnant
	of a context diff, apparently).

1991-01-09  Michael I Bushnell  <mib@pogo.ai.mit.edu>

	* create.c (where_is_data): Rewritten to be better, and then
	#ifdef-ed out.
	(deal_with_sparse): Severly pruned.  Now we write or don't
	write only complete blocks, not worrying about partial blocks.
	This simplifies calculations, removes bugs, and elides the
	second scan through the block.  The first was zero_record, the
	second was where_is_data.

1991-01-07  Michael I Bushnell  <mib@wookumz.ai.mit.edu>

	* create.c (deal_with_sparse): Second computation (for short
	reads) of numbytes increment had subtraction backwards.
	Need to handle calling where_is_data better when we did a
	short read (it might go past the end of the read), also, set
	sparsearray[...].offset in this case too.

1991-01-04  Jay Fenlason <hack@ai.mit.edu>

	* buffer.c: Return a special error code if the archive
	you're trying to read starts with a different label than
	the one specified on the command line.

1991-01-02  Jay Fenlason <hack@ai.mit.edu>

	* gnu.c: Prepend the current directory to the gnu_dumpfile, so that
	-C's won't affect where the output goes. (sigh.)

1990-12-18  Jay Fenlason <hack@ai.mit.edu>

	* gnu.c: Don't complain if the gnudumpfile we're reading info
	from doesn't exist.

	* create.c: Write out gnudumpfile after finishing writing the archive.

	* tar.c: Add +exclude FNAME, and make +exclude-from do what +exclude
	used to.
	* Make +version an operation, not an option.
	* Add +confirmation alias for +interactive.

1990-12-04  Jay Fenlason <hack@ai.mit.edu>

	* tar.c (check_exclude): Don't let MUMBLE match MUMBLE.c or
	fooMUMBLE but only foo/MUMBLE.

	* mangle.c: New file.
	* create.c, extract.c: According changes.

	* extract.c: Don't complain when extracting an already existing link.
	Don't complain when extracting a directory iff it already exists.
	Don't ad u+wx to directories when running as root.
	Reported by Chip Salzenberg.

	* gnu.c: Make +listed-incremental work.
	Reported by Chip Salzenberg.

	* port.c: Add the F_FREESP emulation of the ftruncate syscall.

1990-11-21  Jay Fenlason <hack@ai.mit.edu>

	Remove excess \n from lots of msg() calls.

1990-11-19  Jay Fenlason <hack@ai.mit.edu>

	* tar.c: Rename +volume to +label.

1990-11-16  David J. MacKenzie  <djm@apple-gunkies>

	* tar.c (describe): Include the default values for -b and -f
	(as set in the Makefile) in the message.

1990-11-15  Jay Fenlason <hack@ai.mit.edu>

	* extract.c (extract_archive): Do the utime() call before the
	chmod() call, 'cuz some versons of utime() trash the file's mode
	bits.

	* list.c (read_and): Call do_something on volume headers and
	multivol files even if they don't match the names we're looking
	for, etc.

1990-11-06  Jay Fenlason <hack@ai.mit.edu>

	* port.c (un-quote-string): Don't try to write a null if there's
	already one there.

1990-11-01  Jay Fenlason <hack@ai.mit.edu>

	* buffer.c (new_volume): fflush(msg_file) before reading for
	confirmation on new volume.  On EOF or error, print error msg and
	abort.

1990-10-29  Jay Fenlason <hack@ai.mit.edu>

	* getdate.y: Use new version of getdate().

	* tar.c (name_add): Use sizeof(char *) instead of sizeof(int)

	* README: Give the correct return address.

1990-10-25  Jay Fenlason <hack@ai.mit.edu>

	rtape_lib.c [NO_RMTIOCTL]: Instead of RMTIOCTL, so it is on by default.

	rmt.h [NO_REMOTE]: Add _isrmt() #define.

	gnu.c: Add forward reference for add_dir_name().

1990-10-16  Jay Fenlason <hack@ai.mit.edu>

	Version 1.09 --- New -G file implementation of gnu-dump stuff.

	* tar.c (name_add): Get the calls to ck_realloc and ck_malloc right.

1990-10-11  Jay Fenlason <hack@ai.mit.edu>

	* gnu.c: Fix A couple of typos.

1990-09-19  David J. MacKenzie  <djm@apple-gunkies>

	* getdate.y [USG && !DAYLIGHT_MISSING] (ftime): Use `daylight'.

1990-09-17  Jay Fenlason <hack@ai.mit.edu>

	* gnu.c (gnu_restore): Don't use a passed char* for the
	file name, use skipcrud+head->header.name, just like everything
	else does.  This means that gnu_restore will still work with
	small buffers, etc.

1990-09-13  Jay Fenlason <hack@ai.mit.edu>

	* tar.c (add_exclude): Don't bus-error if the exclude file doesn't
	end with a newline.

1990-09-09  David J. MacKenzie  <djm@albert.ai.mit.edu>

	* Makefile (dist): Remove .fname when done.

1990-09-06  Jay Fenlason <hack@ai.mti.edu>

	* gnu.c (gnu_restore): Rember to skip_file() over the directory
	contents, even if we don't have to do anything with them.

	* create.c, extract.c, diffarch.c: Free sparsearray after we're
	done with it.

1990-09-04  Jay Fenlason <hack@ai.mit.edu>

	* Makefile: Include gnu.c in dist

	* gnu.c: Move add_dir above read_dir_file so that cc doesn't
	complain about add_dir returning void.

1990-09-02  David J. MacKenzie  <djm@apple-gunkies>

	* getdate.y: Declare some more functions and add storage
	classes where omitted to shut compiler up.
	[USG] (ftime): Don't use extern var `daylight'; appears that
	some systems don't have it.

1990-08-29  David J. MacKenzie  <djm@apple-gunkies>

	* getdate.y (lookup): In the code that allows `Aug.' to be
	recognized as `Aug', don't chop off the final `.' from words
	like `a.m.', so they can be recognized.

1990-08-16  Jay Fenlason <hack@ai.mit.edu>

	* buffer.c (open_archive): If -O, write verbosity to stderr
	instead of stdout.

1990-08-10  Jay Fenlason <hack@ai.mit.edu>

	* getdate.y: Handle an explicit DST in the input string.
	Reported by Per Foreby.

1990-07-16  Jay Fenlason <hack@ai.mit.edu>

	* tar.c: rename -g -G +incremental, +listed-imcremental, etc.

1990-07-13  Jay Fenlason <hack@ai.mit.edu>

	* tar.c: Make +newer and +newer-mtime work according to their names.

	* gnu.c: If +newer or +newer-mtime, use the time specified on the
	command line.

	* buffer.c, create.c: Add test to see if dimwit is trying to
	archive the archive.

	* tar.c (long_options[]): Re-ordered, so that groups of similar
	options are next to each other...  I think.

	(describe): Modified to more closely reflect reality.

1990-07-06  Jay Fenlason <hack@ai.mit.edu>

	* tar.c: Add compile-time option for SYS V (?) style
	tape-drive names /dev/rmt/{n}[lmh]

	* tar.c: Fix getopt-style stuff so that -C always works correctly.

	* gnu.c, tar.c: Make filename to -G optional.

	* {all over}: Replace some fprintf(stderr...) calls with calls
	to msg().

	* port.c: Make -Dmumble_MSG option on command line override
	internal assumptions.

	* Makefile: Mention -Dmumble_MSG options

1990-07-06  David J. MacKenzie  <djm@apple-gunkies>

	* tar.c (options): Don't change `c' if it is 0, as getopt now
	handles that internally.

1990-07-02 Jay Fenlason <hack@ai.mit.edu>

	* gnu.c (new file): Moved all the f_gnudump stuff here where we
	can keep track of it easier.  Also made -G take a file name where
	it stores the inode information about directories so that we can
	detect moved directores.

	* create.c (dump_file): Changed slightly to work with the new
	f_gnudump.

	* tar.c: Moved the f_gnudump stuff to gnu.c

	* tar.c, extract.c: Added the +do-chown option, which forces tar
	to always try to chown the created files to their original owners.

	* version.c: New version 1.09

1990-06-24  David J. MacKenzie  <djm@albert.ai.mit.edu>

	* create.c: Change ifdefs for directory library header
	selection to be like the ones in tar.c.
	* Makefile [Xenix]: Link with -ldir to get the dirent.h
	directory library.

1990-06-07  David J. MacKenzie  <djm@albert.ai.mit.edu>

	* Makefile, buffer.c, diffarch.c [HAVE_MTIO]: Instead of MTIO, as
	SCO Xenix defines 'MTIO' for an incompatible tape driver system in
	a file included by termio.h.
	* tar.h: Don't define size_t for Xenix.

1990-06-05  Jay Fenlason <hack@ai.mit.edu>

	* create.c (dump_file): Only print the
	"... is on a different filesystem..." if f_verbose is on.
	also add a case for S_IFSOCK and treat it like a FIFO.
	(Not sure if that's the right thing to do or not, but it's better
	than all those Unknown File Type msgs.)

1990-05-31  Jay Fenlason <hack@ai.mit.edu>

	* port.c [sparc]: Use instead of SPARC since the lowercase version
	is defined, and the uppercase one isn't.

1990-05-22  Jay Fenlason <hack@ai.mit.edu>

	* port.c (ck_malloc): if size==0 pretend size=1
	(ck_realloc): if(!ptr) call ck_malloc instead.

1990-05-15  Jay Fenlason <hack@ai.mit.edu>

	* diffarch.c (diff_archive): If not f_absolute_paths, and attempt
	to open a file listed in the archive fails, try /filename also.
	This will allow diff to open the wrong file if both /filename and
	filename exist, but there's nothing we can do about that.

1990-05-11  Jay Fenlason <hack@ai.mit.edu>

	* Makefile: Describe new -DMTIO option.

	* buffer.c, diffarch.c: Change ifdefs slightly, so that -DMTIO
	will include sys/mtio.h even if USG is defined.  This is for HPUX
	and similar BSD/USG crossovers.

1990-05-08  Jay Fenlason <hack@ai.mit.edu>

	* update.c (update_archive): Call reset_eof() when appropriate.

	* buffer.c (reset_eof): New function, that turns of EOF flag, and
	re-sets the ar_record and ar_last pointers.  This will allow
	'tar rf non-existant-file' to not core-dump.

1990-05-04  David J. MacKenzie  <djm@albert.ai.mit.edu>

	* tar.c: Recognize the +sparse option.  It was documented, but
	only the short form (-S) was actually recognized.

1990-04-17  Jay Fenlason <hack@ai.mit.edu>

	* create.c: Don't access location 0 if ->dir_contents is null.

1990-04-11  Jay Fenlason <hack@ai.mit.edu>

	* buffer.c (flush_archive, close_archive, new_volume): Always
	check the return value of rmtclose(), and only give a warning msg
	if it is <0.  Some device drivers (including Sun floppy disk, and
	HP streaming tape) return -1 after an IO error (or something like
	that.)

1990-03-23  Jim Kingdon  <kingdon@mole.ai.mit.edu>

	* tar.c (long_options): Make it so +append +extract +list +update
	+catenate and +delete don't take arguments.

1990-03-12  Jay Fenlason <hack@ai.mit.edu>

	* buffer.c (open_archive, fl_write): Set the mtime of the volume
	header to the current time.

1990-03-07  Jay Fenlason <hack@ai.mit.edu>

	* buffer.c  Fix +compress-block  A two character patch from
	Juha Sarlin.
	Replace #ifdef __GNU__ with #ifdef __STDC__.
	(new_volume): If open of new archive fails, ask again, as it
	probably is user error.

	* tar.c: Replace #ifdef __GNU__ with #ifdef __STDC__

	* port.c: Clean up #ifdef and #defines a bit.
	(quote_copy_string): Sometimes the malloc'd buffer would be up to
	two characters too short.

	* extract.c (extract_archive): Don't declare ind static.

	* create.c (dump_file): Don't declare index_offset static.

	* diffarch.c: Remove diff_name variable, and always use
	head->header.name, which will always work, unlike diff_name, which
	becomes trash when the next block is read in.

1990-03-01  Jay Fenlason <hack@wookumz.ai.mit.edu>

	* Makefile: Mention the -NO_REMOTE option.
	* port.c [i386]: Fix typo, and define WANT_FTRUNCATE.

1990-02-26  Jim Kingdon  <kingdon@pogo.ai.mit.edu>

	* getdate.y: Declare yylex and yyerror as static.
	#define yyparse to getdate_yyparse.

1990-02-25  David J. MacKenzie  <djm@albert.ai.mit.edu>

	* tar.c: Remove +old option, since it is a valid abbreviation of
	+old-archive, which does the same thing.
	(describe): A few small cleanups in message.

1990-02-05  Jay Fenlason	<hack@wookumz>

	* port.c [sparc]: Define LOSING_MSG, since doprnt_msg doesn't work.
	[WANT_GETWD]: Fix typo.

1990-01-26  Jay Fenlason	<hack@wookumz>

	Version 1.08 --- Sparse file support added.  Also various other
	features.

	* diffarch.c (compare_chunk): Include correct arguments in
	a call to fprintf() for an error msg.
	(compare_chunks, compare_dir): First argument is a long, not an int.

	* tar.c (options): Use tar variable (argv[0]) as the name to print
 	in an error msg, instead of a constant "tar".
	(confirm): Use external variable char TTY_NAME[] for name of file
	to open for confirmation input.

	* buffer.c (new_volume): Ditto.

	* port.c: Add declaration for TTY_NAME[].

	* rmt.h: Add long declarations for lseek() and __rmt_lseek();

1990-01-23  Jay Fenlason <hack@wookumz>

	* tar.c, create.c: Create the +newer-mtime option, which is like
	+newer, but only looks for files whose mtime is newer than the
	given date.

	* rtape_lib.c [USG]: Make *both* instances of signal-handler stuff
	use void (*foo)().

1990-01-11  Jay Fenlason  <hack@wookumz>

	* getdate.y : Parse European dates of the form YYMMDD.
	In ftime(): Init timezone by calling localtime(), and remember that
	timezone is in seconds, but we want timeb->timezone to be in minutes.
	Reported by Jörgen Haegg.

	* rtape_lib.c (__rmt_open): Also look for /usr/bsd/rsh.
	Declare signal handler as returning void instead of int if USG is
	defined.

	* port.c: Declare WANT_GETWD for SGI 4-D IRIS.

	* Makefile: Include defines for SGI 4D version.
	Reported by Mike Muuss.

	* buffer.c (fl_read): Work properly on broken Ultrix systems where
	read() returns -1 with errno==ENOSPC on end of tape.  Correctly go
	on to the next volume if f_multivol.

	* list.c (list_archive, print_header): Flush msg_file after
	printing messages.

	* port.c: Delete unused references to alloca().
	Don't crash if malloc() returns zero in quote_copy_string.
	Flush stderr in msg() and msg_perror().

	* tar.c: Flush msg_file after printing confirmation msg.

1990-01-10  David J. MacKenzie  <djm@hobbes.ai.mit.edu>

	* tar.c (main): Change -help option and references to it to +help,
	and remove suggestion to run info (which is unreleased, so not
	likely to be of any help).

1990-01-09  Jay Fenlason  <hack @wookumz>

	* create.c (dump_file): Close file descriptor if start_header()
	fails.
	(dump_file): Change test for `./'-ness to not think that `.' {any
	character} is a `./'.
	Reported by Piercarlo Grandi.

	* diffarch.c (diff_init): Print correct number of bytes in error
	message.

1990-01-09  David J. MacKenzie  <djm@hobbes.ai.mit.edu>

	* Makefile: Add comment at top noting that two source files also
	contain #defines that might need to be changed by hand.

	* create.c, diffarch.c, extract.c: Change L_SET to 0 in lseek
	calls, because only BSD defines it.
	* create.c (dump_file) [BSD42]: Make sparse file checking code
	conditional because it uses st_blocks, which the other systems lack.

1990-01-02  Jay Fenlason <hack@gnu>

	* port.c (quote_copy_string): Fix so it doesn't scramble memory if
	the last character is non-printable.
	Reported by Kian-Tat Lim.

1989-12-19  Jim Kingdon  <kingdon@pogo>

	* port.c [BSD42]: Define DOPRNT_MSG.
	tar.h [BSD42]: Do not prototype msg{,_perror}.

1989-12-08  Jay Fenlason <hack@gnu>

	* create.c (dump_file): Remove typo in msg.

1989-12-01  David J. MacKenzie  <djm@trix>

	* Makefile: Remove comments referring to certain systems lacking
	getopt, since it is now provided always and needed by all systems.

	* port.c: Remove copy of getopt.c, as it is now linked in
	separately to always get the current version.

	* tar.c: Rename +cat-tars option to +catenate or +concatenate,
	and +local-filesystem to +one-file-system (preferred by rms
	and used in GNU cp for the same purpose).
	(describe): Reflect changes.

1989-11-28  David J. MacKenzie  <djm@hobbes.ai.mit.edu>

	* port.c: Move declaration of alloca into #else /* sparc */
	so it will compile on sparcs.

1989-11-27  David J. MacKenzie  <djm@hobbes.ai.mit.edu>

	* tar.c (options): Remove -version option (replaced by +version).
	(describe): Mention long options.

1989-11-25  David J. MacKenzie  <djm@hobbes.ai.mit.edu>

	* getoldopt.c (getoldopt): Make `opt_index' argument a pointer to
	an int, not char.

	* tar.c: Modify long options per rms's suggestions:
	Make preserve-permissions an alias for same-permissions.
	Make preserve-order an alias for same-order.
	Define preserve to mean both of those combined.
	Make old an alias for old-archive.
	Make portability an alias for old-archive, also.
	Rename sym-links to dereference.
	Rename gnudump to incremental.
	Rename filename to file.
	Make compare an alias for diff.  Leave diff but prefer compare.
	Rename blocking-factor to block-size.
	Rename chdir to directory.
	Make uncompress an alias for compress.
	Rename confirm to interactive.
	Make get an alias for extract.
	Rename volume-header to volume.

	Also make +version an alias for -version.

	(options): Shorten code that interprets long options by using
	the equivalent short options' code.  This also makes it tons
	easier to change the long options.

	(describe): Make usage message more internally consistent
	stylistically.

1989-11-20	hack@ai.mit.edu

	* list.c (read_and): Call check_exclude() to see if the files
	should be skipped on extract or list.

1989-11-09  Jim Kingdon  <kingdon@hobbes.ai.mit.edu>

	* buffer.c (fl_read): Fix typos in error message
	"tar EOF not on block boundary".

1989-10-23		<hack@ai.mit.edu>

	* tar.c (long_options[]): Add an option for blocked compression.

1989-10-19		<hack@ai.mit.edu>

	* buffer.c (writeerror): Print a more useful error msg.

1989-09-27		<hack@ai.mit.edu>

	* tar.c (main): Mention "tar -help" if the luser types a non-workable
	set of options.

1989-09-11		<hack@ai.mit.edu>

	* tar.c (options): Have -F correctly set info_script.

1989-08-29		<hack@ai.mit.edu>

	* Makefile  Include ChangeLog in tar.tar and tar.tar.Z

1989-08-28		<hack@ai.mit.edu>

	* tar.c (options) Made -F imply -M.
	Also remind tar that the -f option takes an argument!

	* Modified -F option to make it do what (I think) it
	should.  e.g, if you say -F, tar won't send a msg to
	msg_file and wait for a <return> It'll just run the program
	it was given, and when the prog returns, the new tape had
	*better* be ready...

	* buffer.c (open_archive): Give error message and abort if
	the luser didn't give an archive name.

1989-08-25		Joy Kendall <jak@hobbes>

	* Added code to make a new option to run a specified script at
	the end of each tape in a multi-volume backup.	Changed: tar.c:
	made new switch, -F, and new long-named option, "info-script".
	Code is where you would expect.
	* tar.h: added flag f_run_script_at_end, and an extern char *
	called info_script, which optarg gets set to.
	* buffer.c (new_volume): if f_run_script_at_end is set, we give
	info_script to system(), otherwise we do what we've always done.

1989-08-24		Joy Kendall <jak@spiff>
(These changes made over the course of 6/89 - 8/89)

	* diffarch.c: diff_archive: Added switches for LF_SPARSE in the
	case statements that needed it.  Also, skip any extended headers
	if we need to when we skip over a file.  (need to change the bit
	about, if the size doesn't agree AND the file is NOT sparse,
	then there's a discrepancy, because I added another field to
	the header which should be able to deal with the sizes): If
	the file is sparse, call the added routine "diff_sparse_files"
	to compare.  Also added routine "fill_in_sparse_array".

	* extract.c: extract_archive: added the switch LF_SPARSE to the
	case statement as needed, and code to treat the sparse file.
	At label "again_file", modified opening the file to see if we
	should have O_APPEND be one of the modes.  Added code at label
	"extract_file" to call the new routine "extract_sparse_file"
	when we have an LF_SPARSE flag.

	Note: really should erase the commented-out code in there,
	because it's confusing.

	* update.c: made sure that if a file needed to be "skipped"
	over, it would check to see if the linkflag was sparse, and if
	so, would then make sure to skip over any "extended headers"
	that might come after the header itself.  Do so by calling
	"skip_extended_headers".

	* create.c: create_archive: added code to detect a sparse file
	when in the long case statement.  Added ways to detect extended
	headers, and label "extend" (ack! should get rid of that, is
	atrocious).  Call the new routine "finish_sparse_file" if the
	linkflag is LF_SPARSE to write the info to the tape.  Also added
	routines "init_sparsearray", "deal_with_sparse", "clear_buffer",
	"where_is_data", "zero_record", and "find_new_file_size".

	* tar.h: Added the #define's SPARSE_EXT_HDR and SPARSE_IN_HDR.
	Added the struct sparse and the struct sp_array.  Added the
	linkflag LF_SPARSE. Changed the tar header in several ways:
	- added an array of struct sparse's SPARSE_IN_HDR long
	- added a char flag isextended
	- added a char string realsize to store the true size of a sparse file
	Added another choice to the union record called a struct
	extended_header, which is an array of 21 struct sparse's and a
	char isextended flag.  Added flag f_sparse_file to list of flags.

	* tar.c: added long-named options to make tar compatible with
	getopt_long, changed Makefile.

(I'm not completely sure all these have been integrated -- FP.)

	* buffer.c [USG]: ifdef'd out #include <sys/file.h>.
	(close_archive): SysV doesn't have ftruncate, so substituted
	fmtwrite (just copied the code for MS-DOS).
	* create.c: Unos lacks <sys/sysmacros.h> so provided a substitute.
	(start_header): Only strip leading paths if f_relative_paths is true.
	* extract.c:
	(extract_archive): Only strip leading paths if
	f_relative_paths is true.  Because the Unos filesystem has
	only one timestamp, moved the utime call to after the chown
	and chmod calls.
	* getdate.y: Don't define ftime if Unos.
	* list.c: Defined size_t for Unos.  [USG]: Don't include <sys/file.h>.
	Define <sys/sysmacros> stuff manually for Unos.
	(decode_header): Add braces around switch cases; some compilers
	require them.
	(print_header): Changed UGSWIDTH from 11 to 25 because the smaller
	value made tape listings of files owned by more than one user
	gradually get wider, making them hard to read.
	* port.c: Don't include <sys/file.h> if SysV.  Define
	size_t for Unos.
	(mkdir): Add code to support Unos makedir sys call.
	(getopt): Use malloc instead of alloca, because tar doesn't
	use alloca anywhere else and many systems lack it.  A few other
	changes from the current version of getopt.c incorporated.
	* rtape_lib.c: Undefine RMTIOCTL.  Doesn't seem to be needed,
	and can't compile on Unos/SysV with it defined.  Might need to be
	ifdef'd.
	* tar.c: Alias addname to add_name and rmdir to deldir on Unos
	due to C library weirdness.
	(options): Recognize new -P option to set f_relative paths.
	(describe): Clean up error message and add -P description.
	* tar.h: Add variable, f_relative_paths, to cause tar to strip
	leading `/' characters in pathnames during create and extract.
	* tar.texinfo: Fixed a couple of typos, detected by texi2roff.
	* update.c: Simulate <sys/sysmacros.h> for Unos.

Previous releases by Jay Fenlason (hack@ai.mit.edu)

	* Version 1.07 --- New version to go on beta tape with GCC 1.35.
	Better USG support.  Also support for __builtin_alloca if we're
	compiling with GCC.

	* diffarch.c: Include the correct header files so MTIOCTOP
	is defined.
	* tar.c:  Don't print the verbose list of options unless
	given -help.  The list of options is *way* too long.

	* Version 1.06 --- [__STDC__]: Use STDC_MSG.
	ENXIO meand end-of-volume in archive (for the UNIX PC)
	Added break after volume-header case (line 440) extract.c
	Added patch to rtape_lib.c (reported by Arnold Robbins).
	Added f_absolute_paths option.
	Deleted refereces to UN*X manual sections (dump(8), etc)
	Fixed to not core-dump on illegal options
	Modified msg_perror to call perror("") instead of perror(0)
	patch so -X - works
	Fixed tar.c so 'tar cf - -C dir' doesn't core-dump
	tar.c (name_match): Fixed to chdir() to the appropriate
	directory if the matching name's change_dir is set.  This
	makes tar xv -C foo {files} work.

	* Version 1.05 --- A fix to make confirm() work when the archive is
	on stdin; include 'extern FILE *msg_file;' in pr_mkdir().
	* tar.h [__STDC__]: Fix to work.

	Added to port.c: mkdir() ftruncate(): Removed: lstat()
	Fixed -G to work with -X
	Another fix to tar.texinfo
	Changed tar.c to say argv[0]":you must specify exactly ...
	buffer.c: modified child_open() to keep tar from hanging when
	it is done reading/writing a compressed archive
	added fflush(msg_file) before printing error messages
	create.c: fixed to make link_names non-absolute

	* Version 1.04 --- Added functions msg() and msg_perror(): Modified
	all the files to call them.  Also checked that all (I hope) calls
	to msg_perror() have a valid errno value.
	(modified anno() to leave errno alone), etc.
	Re-fixed the -X option.  This time for sure...
	re-modified the msg stuff.  flushed anno() completely
	Modified the directory stuff so it should work on sysV boxes
	added ftime() to getdate.y
	Fixed un_quote_string() so it won't wedge on \" Also fixed
	\ddd (like \123, etc)
	More fixes to tar.texinfo

	* Version 1.03 --- Fixed buffer.c so 'tar tzf NON_EXISTENT_FILE'
	returns an error message instead of hanging forever.
	More fixes to tar.texinfo.

	* Version 1.02 --- Fixed tar.c so 'tar -h' and 'tar -v' don't cause
	core dump.  Also fixed the 'usage' message to be more up-to-date.
	* diffarch.c [!MTIOCTOP]: Fixed so verify should compile.

	* Version 1.01 --- Fixed typoes in tar.texinfo.
	Fixed a bug in the #define for rmtcreat().
	Fixed the -X option to not call realloc() of 0.

	* Version 1.00 --- version.c added.  -version option added.
	Installed new version of the remote-tape library.
	Added -help option.
