        prereq.m4, xstrtoimax.m4.

        * po/POTFILES.in: Remove tests/genfile.c; it doesn't need to
        be translated, since it's not a user-visible tool.

        * scripts/Makefile.am (AUTOMAKE_OPTIONS): Remove.

        * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.
        (INCLUDES): Remove ../intl.  Put top-srcdir before ., for
        consistency with coreutils.
        (LDADD): Link LIBINTL after libtar.a, since
        it's now external and should stand by itself.

        * src/buffer.c (print_total_written): Adjust to new human.h
        interface.
        (child_open_for_compress): Do not increase size to BLOCKSIZE.

        Strip trailing slahes from file names.
        (flush_write): Set size to 0 if not saving names.

        inline code.

        * src/common.h: Include <quote.h>.
        (absolute_names_option, atime_preserve_option, backup_option,
        block_number_option, checkpoint_option, dereference_option,
        force_local_option, ignore_failed_read_option, ignore_zeros_option,

        (diff_archive): Do not count trailing slashes in archives.
        (verify_volume): Test for header failure after loop, not before.

        * src/create.c (relativize): Remove; replaced by safer_name_suffix.

        (start_header): Clear devmajor and devminor fields, too.
        (finish_header): New arg block_ordinal.
        (init_sparsearray): Now extern.  Set sp_array_size to
        SPARSES_IN_OLDGNU_HEADER if it is zero.
        (dump_file): Keep link table as a hash.
        Do not count "file changed as we read it" as a failure.

        * src/delete.c (recent_long_name_blocks, recent_long_link_blocks):
        Move extern decl to common.h.

        * src/extract.c (we_are_root): Now bool, not int.

        (extract_sparse_file): Now returns off_t, giving size left.
        Truncate file at end.

        Use fill_in_sparse_array rather than rolling our own.
        Strip trailing slashes more effectively.
        Check for unsafe names.

        * src/incremen.c (struct directory): nfs and found are now of type
        bool, not int.
        (gnu_restore): Now takes directory name as argument, not offset
        of directory name in a global.  All uses changed.
        (CURRENT_FILE_NAME): Remove.

        New tests.
        * tests/delete04.sh, tests/multiv01.sh, tests/options.sh: New
        files.

2002-09-30  Paul Eggert  <eggert@twinsun.com>

        * src/rmt.c (prepare_input_buffer): Renamed form
        prepare_record_buffer.  All uses changed.  Do not assume that
        size_t is the same width as int.

2002-03-29  Paul Eggert  <eggert@twinsun.com>

        * src/incremen.c (get_directory_contents):
        If ignore_failed_read_option, only warn about
        get_directory_contents failures.  Fix suggested by
        Mark Costlow.

2002-01-31  Mark W. Eichin  <eichin@thok.org>

        * src/buffer.c (child_open_for_compress): Don't try to read
        past the end of the buffer.

2001-10-11  Jim Meyering  <meyering@lucent.com>

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

2001-09-26  Paul Eggert  <eggert@twinsun.com>

        * NEWS, configure.ac (AM_INIT_AUTOMAKE): Version 1.13.25.

        * src/buffer.c (flush_read): Don't diagnose partial blocks before
        end of file; just ignore them silently.

        * src/list.c (read_header): Don't keep around extended name
        and link info indefinitely; keep it only for the next file.
        This fixes a bug introduced in 1.13.24, and removes the need
        for some static variables.  Set recent_long_name and
        recent_long_link to zero if there were no long links; this
        avoids a violation of ANSI C rules for pointers in delete.c.
        * THANKS: Add Christian Laubscher.

2001-09-26  Jim Meyering  <meyering@lucent.com>

        * doc/tar.texi (Remote Tape Server): is know -> is known

2001-09-25  Paul Eggert  <eggert@twinsun.com>

        * lib/unicodeio.c (EILSEQ): Include <iconv.h> first, since
        <iconv.h> may define EILSEQ (e.g. libiconv).  Define a
        replacement EILSEQ to be ENOENT, not EINVAL, since callers may
        want to distinguish EINVAL and EILSEQ.

2001-09-24  Christophe Kalt  <Christophe.Kalt@kbcfp.com>

        * src/extract.c (maybe_recoverable):
        Treat OVERWRITE_OLD_DIRS like DEFAULT_OLD_FILES.

2001-09-22  Paul Eggert  <eggert@twinsun.com>

        * lib/print-copyr.c, lib/print-copyr.h, lib/unicodeio.c,
        lib/unicodeio.h: New files.

        * lib/error.c, lib/getopt.c, lib/getopt.h, lib/getopt1.c,

        * tests/Makefile.am (LDADD): Likewise.

        * src/buffer.c (write_archive_buffer, close_archive):
        If an archive is a socket, treat it like a FIFO.

        (open_archive, flush_write, flush_read): Keep records_read and
        records_written up to date.

        * src/common.h (enum old_files): New value OVERWRITE_OLD_DIRS.
        (write_archive_to_stdout): Now bool, not int.
        (enum read_header): New value HEADER_SUCCESS_EXTENDED.
        (read_header): Now takes bool arg.  Existing callers modified
        to pass 0, unless otherwise specified.

        * src/delete.c (records_read): Remove; now a global.
        (acting_as_filter): Now bool, not int.
        (recent_long_name, recent_long_link, recent_long_name_blocks,
        recent_long_link_blocks, records_read, records_written): New decls.
        (records_skipped): New var.
        (move_archive): Don't divide by zero if arg is 0.
        Use the above vars to compute how far to move.
        (write_recent_blocks): New function.
        (delete_archive_member): Pass 1 to read_header, so that it doesn't
        read more than 1 block.  Handle resulting HEADER_SUCCESS_EXTENDED code.
        Keep track of how many records have been skipped.
        Let the buffer code count records.
        When copying a header, copy any extended headers that came before it.

        * src/extract.c (extract_archive): When marking a directory to be
        updated after symlinks, stat all directories after it in the
        delayed-set-stat list too, since they will be checked after
        symlinks.  Add support for --overwrite-dir.

        * src/list.c (recent_long_name, recent_long_link,
        recent_long_name_blocks, recent_long_link_blocks): New vars.
        (read_and): Pass 0 to read_header.

2001-09-20  Jim Meyering  <meyering@lucent.com>

        * lib/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).
        * m4/xstrtoimax.m4 (jm_AC_PREREQ_XSTRTOIMAX):

        * configure.ac (LIBOBJS):
        Remove automake 1.4 workaround, as we're using 1.5 now.
        (USE_INCLUDED_LIBINTL): New AC_DEFINE.

        * lib/copysym.c: Include stddef.h, for size_t.
        Include langinfo.h if needed.
        Use locale_charset only if USE_INCLUDED_LIBINTL;
        if not, use nl_langinfo (CODESET) if available.

2001-09-13  Paul Eggert  <eggert@twinsun.com>

        * config.guess, config.sub: Sync with canonical versions.

        * src/rmt.c: Include copysym.h.
        (main): Use copyright_symbol to translate copyright notice,
        instead of gettext.
        * src/tar.c: Likewise.
        * tests/genfile.c: Likewise.

        * src/system.h (MB_LEN_MAX): New symbol.

        'after_symlinks'.
        (delay_set_stat): Initialize it to 0.

        taking an extra stat ourselves.  All callers changed.
        (set_stat): Likewise.
        (apply_nonancestor_delayed_set_stat): New arg 'after_symlinks'.
        If false, stop when encountering a struct whose 'after_symlinks'
        member is true.  Otherwise, go through all structures but check
        them more carefully.  All callers changed.
        (extract_archive): When extracting a deferred symlink, if its parent
        directory's status needs fixing, then mark the directory as needing
        to be fixed after symlinks.
        (extract_finish): Fix status of ordinary directories, then apply
        delayed symlinks, then fix the status of directories that are
        ancestors of delayed symlinks.

        * src/rtapelib.c (rexec):
        Remove declaration; it ran afoul of prototypes on Crays.
        Reported by Wendy Palm of Cray.

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

        * lib/strtoimax.c (HAVE_LONG_LONG):
        Redefine to HAVE_UNSIGNED_LONG_LONG if unsigned.
        (strtoimax): Use sizeof (long), not
        sizeof strtol (ptr, endptr, base),
        to work around bug in IBM C compiler.

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

        * lib/xgetcwd.c: Include "xalloc.h".
        (xgetcwd): Do not return NULL when memory is exhausted; instead,
        report an error and exit.

        * lib/exclude.c (fnmatch_no_wildcards):
        Fix typo that caused us to do case-folding
        search even when that was not desired.  This occurred only in the
        no-wildcard case.

        * lib/xgetcwd.c: 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.

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

2001-09-02  Paul Eggert  <eggert@twinsun.com>

        * lib/xgetcwd.c: Fix typo in local var; from Jim Meyering.

2001-09-01  Jim Meyering  <meyering@lucent.com>

        * 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  <meyering@lucent.com>

        * lib/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>

        * lib/utime.c: Include full-write.h.

        This fixes a bug reported by Jose Pedro Oliveira.

        * src/create.c (dump_file): Use offsetof when computing sizes for
        struct hack; this avoids wasted space in some cases.
        * src/incremen.c (note_directory, find_directory): Likewise.
        * src/names.c (name_gather, addname): Likewise.

        * src/extract.c (extract_archive): Use strcpy, not memcpy,
        for consistency with other code that does similar things.

        * src/names.c (read_name_from_file, name_next, name_gather,
        add_hierarchy_to_namelist): Avoid quadratic behavior when
        reallocating buffers.  Check for buffer size overflow.

2001-08-27  Paul Eggert  <eggert@twinsun.com>

        * NEWS, configure.ac (AC_INIT_AUTOMAKE): Version 1.13.20.

        The biggest change is the new --exclude semantics and options.
        The basic idea was suggested by Gerhard Poul; thanks!

        * NEWS: Describe new --exclude semantics and options, and bug fixes.
        * README: ignfail.sh fails on some NFS hosts.
        * NEWS, README, lib/xstrtol.h: Add copyright notice.

        * Makefile.am (ACLOCAL_AMFLAGS): Add -I m4.
        (M4DIR, ACINCLUDE_INPUTS, $(srcdir)/acinclude.m4):
        Remove; the automake bug has been fixed.
        * acinclude.m4: Remove.

        * configure.ac: Renamed from configure.in.
        (AC_PREREQ): Bump from 2.13 to 2.52.
        (ALL_LINGUAS): Add id, tr.  Remove ko, as po/ko.po (dated
        1997-05-30) has an encoding error.
        (jm_AC_HEADER_INTTYPES_H): Remove; now done by autoconf.
        (AC_FUNC_FNMATCH): Use AC_CONFIG_LINKS, not AC_LINK_FILES.

        * doc/fdl.texi: Update to current GNU version.

        * doc/tar.texi: Put leading '*' in direntry.
        Accommodate new gfdl sectioning.

        --no-recursion.

        New options --anchored, --ignore-case, --wildcards,
        --wildcards-match-slash, and their negations (e.g., --no-anchored).
        Along with --recursion and --no-recursion, these control how exclude
        patterns are interpreted.  The default interpretation of exclude
        patterns is now --no-anchored --no-ignore-case --recursion
        --wildcards --wildcards-match-slash.

        * lib/Makefile.am (OMIT_DEPENDENCIES): Remove.

        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.

        New macros.
        (free_exclude): New decl.
        (add_exclude, add_exclude_file): Now takes int options arg.

        we use strlen.

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

        * lib/xstrtol.h (_DECLARE_XSTRTOL): Improve quality of

        * m4/xstrtoumax.m4: Upgrade to serial 3, but then:
        (jm_AC_PREREQ_XSTRTOUMAX): Remove jm_AC_HEADER_INTTYPES_H, as
        it is now subsumed by autoconf.  Add inttypes.h.

        * po/cs.po, po/da.po, po/de.po, po/es.po, po/et.po, po/fr.po,
        po/it.po, po/pl.po, po/sl.po, po/sv.po: Sync with translation project.

        'sources' and 'target' member.  All uses changed.

        (struct string_list): New type.

        (delayed_set_stat, extract_archive): Use offsetof when computing sizes
        for struct hack; this avoids wasted space in some cases.

        (extract_archive): Fix test for absolute pathnames and/or "..".
        Use link_error to report errors for links.
        Remove redundant trailing '/' at "really_dir", for all uses, not
        just before invoking mkdir.
        If overwriting old files, do not worry so much about existing
        directories.
        Fix mode computation in the case where the directory exists.

        (apply_delayed_symlinks): If we can't make a hard link to a symbolic
        link, make a copy of the symbolic link.

        * src/incremen.c (get_directory_contents):
        If ignore_failed_read_option, only warn about
        stat failures.

        * src/list.c (from_header): Do not issue a diagnostic if TYPE is zero.
        However, check for error even for '-' or '+' case.

        (print_header): Try parsing uids and gids as unsigned integers first,
        and as a uid_t or gid_t only if that fails.  This adds support for
        listing positive uids and gids that are greater than UID_MAX and
        GID_MAX.

        * src/misc.c (link_error): New function.

        * src/rtapelib.c (base_name): Remove decl, as system.h now
        declares it.

        * src/system.h: Include stddef.h if available.
        (offsetof): Declare if stddef.h doesn't.

        Include <dirname.h>.

        (decode_options): Implement the new way of interpreting exclude
        patterns.

        (usage): --newer-mtime takes a DATE operand.  DATE may be a file name.

        (errno): Declare if not defined.
        (addext): Work correctly on the Hurd, where pathconf returns -1 and
        leaves errno alone, because there is no limit.  Also, work even if
        size_t is narrower than long.

        Handle filesystem prefixes.
        (start_header): Use this new function.
        (init_sparsearray): Don't bother to zero out the new array;
        it's not needed.
        (deal_with_sparse): Fix array allocation bug.
        (create_archive): Don't assume '/' is the only separator.
        (dump_file): Likewise.
        Don't worry about leading / in symlink targets.

        * lib/savedir.c (savedir):
        Remove size arg; it wasn't portable.  All callers changed.

        (time): Declare if not defined.

        * lib/full-write.c: Include full-write.h, not safe-read.h.

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

        * lib/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>

        * lib/fnmatch.c (FOLD): Do not assume that characters are unsigned.

        (long_options): Have getopt set the --no-recursion flag.
        (decode_options): Initialize recursion_option to FNM_LEADING_DIR.
        Remove case for NO_RECURSE_OPTION.
        * src/common.h (recursion_option):
        Renamed from no_recurse_option, with sense
        negated, and with FNM_LEADING_DIR being the nonzero value.

        * names.c (namelist_match): New function.
        (name_match, name_scan): Use it to eliminate duplicate code.
        (names_notfound): Remove special case for Amiga.

2000-10-27  Paul Eggert  <eggert@twinsun.com>

        * src/misc.c (read_error_details, read_warn_details,
        read_fatal_details): Don't assume size_t is unsigned long.

        * src/buffer.c (flush_read): If read_full_records_option, try to
        fill the input buffer, as --delete -f - needs this.

2000-10-24  Paul Eggert  <eggert@twinsun.com>

        * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Port to autoconf 2.13.

        Make sure header name is a string before
        passing it to fnmatch.

        (new_volume): Check for global_volno overflow.

        * src/tar.c (decode_options):
        Check that volume label is not too long to overflow
        name in tar header block.

        * Makefile.am (EXTRA_DIST): Remove rebox.el.

        * configure.in (HAVE_DECL_STRERROR_R): Remove our handwritten code.

2000-10-23  Paul Eggert  <eggert@twinsun.com>

        * src/extract.c: Include <time.h>, since we invoke "time".

        * lib/prepargs.c (prepend_default_options):

        nametail, with one extra level of indirection.
        (name_gather): Use memcpy instead of strncpy + assignment of NUL.
        (name_match): Set nametail too, when setting namelist to null.
        (add_hierarchy_to_namelist): Change type of dir arg from char * to
        struct name *, so that we don't have to look up the name again
        here.  Get change_dir from dir rather than as a separate arg.  Add
        dirsize arg, and pass it along to get_directory_contents.  Remove
        unnecessary check of directory type.
        (new_name): Do not append a slash if PATH already ends in one.
        (avoided_names, struct avoided_name): Remove.
        (avoided_name_table): New var, replacing avoided_names.
        (hash_avoided_name, compare_avoided_names): New function.
        (add_avoided_name, is_avoided_name): Use hash table rather than
        linked list.

        * src/buffer.c (_GNU_SOURCE): Remove; autoconf now does this.
        (child_open_for_compress, child_open_for_uncompress,
        close_archive): Propagate any failure of the compression process
        back to "tar".
        (open_archive, flush_write, flush_read, close_archive): Do not
        allocate an array of size PATH_MAX, as PATH_MAX might be (size_t)
        -1.  Instead, allocate an array with the size that's needed.
        (open_archive): Don't bother checking S_ISCHR of /dev/null.
        (backspace_output): Don't try to backspace past start of archive.
        (close_archive): Remove special case for DELETE_SUBCOMMAND.

        * acconfig.h (_GNU_SOURCE, DEFAULT_ARCHIVE, DEFAULT_BLOCKING,
        DENSITY_LETTER, DEVICE_PREFIX, EMUL_OPEN3, HAVE_GETGRGID,
        HAVE_GETPWUID, HAVE_MKNOD, HAVE_RTAPELIB, HAVE_ST_FSTYPE_STRING,
        HAVE_UNION_WAIT, HAVE_UTIME_H, HAVE_VALLOC, MTIO_CHECK_FIELD, PACKAGE,
        PROTOTYPES, REMOTE_SHELL, STD_INC_PATH, VERSION, WITH_CATALOGS,
        WITH_DMALLOC, WITH_REGEX):
        Remove; now generated automatically.

        * configure.in (_GNU_SOURCE): Define to empty, not 1, for
        compatibility for glibc fragments.
        (_GNU_SOURCE, HAVE_UTIME_H, MTIO_CHECK_FIELD,
        HAVE_ST_FSTYPE_STRING, HAVE_MKNOD, REMOTE_SHELL, DENSITY_LETTER,
        DEVICE_PREFIX, DEFAULT_ARCHIVE, DEFAULT_BLOCKING): Add comment so
        that we needn't put an entry into acconfig.h.
        (ALL_LINGUAS): Add da.
        (AC_C_BACKSLASH_A): Remove; jm_PREREQ_QUOTEARG now does this.
        (AC_CHECK_HEADERS): Add stdbool.h (for hash.h users), wctype.h
        (for strtol.c).
        (AC_MBSTATE_T): Add.
        (RMT): Append $(EXEEXT).
        (HAVE_GETGRGID, HAVE_GETPWUID, pe_AC_TYPE_SIGNED_CHAR): Remove.
        (HAVE_DECL_FREE, HAVE_DECL_GETGRGID, HAVE_DECL_GETPWUID,
        HAVE_DECL_GETENV, HAVE_DECL_MALLOC, HAVE_DECL_STRTOUL,
        HAVE_DECL_STRTOULL, HAVE_DECL_STRERROR_R): New macros.
        (jm_PREREQ_ADDEXT, jm_PREREQ_ERROR, jm_PREREQ_QUOTEARG): Add.
        (AC_REPLACE_FUNCS): Remove execlp; no longer needed.
        (AC_CHECK_FUNCS): Add clock_gettime; AC_SEARCH_LIBS wasn't enough.
        Remove mbrtowc; jm_PREREQ_QUOTEARG now does this.
        (EMUL_OPEN3): Remove; no longer needed.
        (DENSITY_LETTER, DEVICE_PREFIX): Simplify m4 quoting.

        * m4/fnmatch.m4 (AC_FUNC_FNMATCH): Detect d*/*1 vs d/s/1 bug.

        * src/common.h: Do not include basename.h.
        * src/rtapelib.c (base_name): Do not include basename.h;
        declare base_name instead.

        * lib/basename.h, lib/execlp.c, lib/getpagesize.h, lib/mkdir.c:
        Remove these files.
        * lib/getstr.c, lib/getstr.h, lib/hash.h, lib/hash.h, lib/prepargs.c,
        lib/prepargs.h, lib/savedir.c, lib/savedir.h: New files.
        * lib/Makefile.am (EXTRA_DIST, noinst_HEADERS, libtar_a_SOURCES):
        Adjust to the above changes.

        * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove ../src/ansi2knr.

        * src/open3.c: Remove.

        * src/Makefile.am (AUTOMAKE_OPTIONS): Remove ansi2knr.
        (tar_SOURCES): Remove open3.c.
        (INCLUDES): Remove -I.., as automake does that.
        (OMIT_DEPENDENCIES): ../lib/fnmatch.h -> fnmatch.h.  Add localedir.h.

        The following changes are to put LOCALEDIR into localedir.h instead
        of passing it on the command line.
        (DEFS): Remove.
        (DISTCLEANFILES): New macro.
        (localedir.h): New rule.
        (rmt.o tar.o): Now depend on localedir.h.

        * tests/delete02.sh, tests/extrac04.sh: New files.

        * tests/Makefile.am (AUTOMAKE_OPTIONS): Remove ansi2knr.
        (TESTS): Add extrac04.sh, and restore delete02.sh.
        (DEFS): Remove; LOCALEDIR is now done via localedir.h.
        (INCLUDES): Remove -I.. as automake does this now.

        * src/rtapelib.c (rexec): Don't declare unless using it.
        (do_command): Simplify signal-handling code slightly.

        * src/delete.c (blocks_needed): Remove.  All uses changed to use
        blocking_factor - new_blocks.
        (acting_as_filter): New var.
        (write_record, delete_archive_members): Use acting_as_filter
        rather than archive == STDIN_FILENO to detect whether we're acting
        as a filter, as open can return STDIN_FILENO in some cases.
        (delete_archive_members): Ignore zero blocks if
        ignore_zeros_option is nonzero.  Fix bug that messed up last
        output block: write_eot can't be used here, as it gets confused
        when the input is at end of file.

        * src/compare.c (diff_archive): Do not impose an arbitrary limit on
        symbolic link contents length.  Pass directory size to
        get_directory_contents.

        * m4/decl.m4, m4/error.m4, m4/mbstate_t.m4, m4/prereq.m4,
        m4/strerror_r.m4: New files.
        * m4/signedchar.m4: Remove this file.
        * Makefile.am (ACINCLUDE_INPUTS): Adjust to above changes.
        * m4/Makefile.am (EXTRA_DIST): Likewise.

        * Makefile.am (DISTCLEANFILES): Add intl/libintl.h.

        * po/da.po: New translation file.

        * src/mangle.c (extract_mangle):
        Fix diagnostic with wrong number of %s'es.

        * lib/fnmatch.c (fnmatch):
        Fix some FNM_FILE_NAME and FNM_LEADING_DIR bugs,
        e.g. fnmatch("d*/*1", "d/s/1", FNM_FILE_NAME) incorrectly yielded zero.

        * lib/full-write.c (full_write): Some buggy drivers return 0 when you
        fall off a device's end.  Detect this.

        * src/system.h (IN_CTYPE_DOMAIN): Renamed from CTYPE_DOMAIN.  All
        uses changed.
        (open): Remove macro; we no longer support EMUL_OPEN3.  Do not
        include <pathmax.h> and directory include files like <dirent.h>;
        no longer used.  Include <savedir.h> instead.
        (closedir, signed_char): remove macro; no longer used.
        (bool, false, true): Include <stdbool.h> if you have the include
        file, otherwise define.

        * src/misc.c:
        (is_dot_or_dotdot, closedir_error, closedir_warn, opendir_error,
        opendir_warn, readdir_error): Remove; no longer needed.
        (safer_rmdir): Strip leading ./ (or .// or ./// or ././ or etc.)
        before deciding whether we're trying to remove ".".
        (remove_any_file): Try unlink first if we are not root.  Use
        savedir when recursively removing directories, to avoid exhausting
        file descriptors.
        (savedir_error, savedir_warn, symlink_error): New functions.

        * src/list.c: (read_and): Do not invoke
        apply_nonancestor_delayed_set_stat; DO_SOMETHING is now
        responsible for that.  Do not invoke apply_delayed_set_stat; our
        caller is now responsible for that.
        (read_header): Use signed char instead of signed_char.  Prevent
        later references to current_header from mistakenly treating it as
        an old GNU header.
        (from_header): Quote invalid base-64 strings in diagnostics.
        (time_from_header): Do not warn about future timestamps in
        archive; check_time now does that.
        (print_header): Quote unknown file types.
        (skip_member): New function, replacing skip_extended_headers and
        now skipping the whole member instead of just the extended
        headers.  All callers changed.  This makes the code handle
        extended headers uniformly, and fixes some bugs.

        * src/update.c (update_archive): Use skip_member.

        * src/extract.c (we_are_root): Now global.
        (struct delayed_symlink): New type.
        (delayed_symlink_head): New var.
        (extr_init, fatal_exit): Invoke extract_finish on fatal errors,
        not apply_delayed_set_stat.
        (set_mode, set_stat): Pointer args are now const pointers.
        (check_time): New function.
        (set_stat): Warn if setting a file's timestamp to be the future.
        (make_directories): Do not save and restore errno.
        (maybe_recoverable): Set errno to ENOENT if we cannot make missing
        intermediate directories.
        (extract_archive): Invoke apply_nonancestor_delayed_set_stat here,
        not in caller.  Extract potentially dangerous symbolic links more
        carefully, deferring their creation until the end, and using a
        regular file placeholder in the meantime.  Do not remove trailing
        / and /. from file names.  Do not bother checking for ".." when
        checking whether a directory loops back on itself, as loopbacks
        can occur with symlinks too.  Also, in that case, do not bother
        saving and restoring errno; just set it to EEXIST.
        (apply_nonancestor_delayed_set_stat): A prefix is a potential
        ancestor if it ends in slash too (as well as ending in a char just
        before slash).
        (apply_delayed_set_stat): Remove.
        (apply_delayed_symlinks, extract_finish): New functions.

        * doc/fdl.texi: New file.
        * doc/Makefile.am (EXTRA_DIST): Add fdl.texi.
        ($(srcdir)/tar.info): Add fdl.texi.  Invoke makeinfo with --no-split.
        * doc/tar.texi: Add Free Documentation License.  New section
        "Overwrite Old Files", and revamp that section to make it easier to
        follow.  "tar" -> "GNU tar" where appropriate.  Migrate getdate
        documentation into getdate.texi.  Fix several minor typos.  Describe
        TAR_OPTIONS.  Describe incompatibility between incremental backups and
        --atime-preserve.  Describe incompatibility between --verify and other
        options.  Mention that tar normally removes symbolic links rather than
        following them, when extracting a file of the same name.

        * THANKS: Add gpoul.  Change skip's address.

        * po/POTFILES.in: Add lib/human.c.

        * src/common.h (namelist, namelast): Remove decls.
        (we_are_root, extract_finish, skip_member, savedir_error,
        savedir_warn, symlink_error, gnu_list_name): New decls.
        (apply_delayed_set_stat, apply_nonancestor_delayed_set_stat,
        skip_extended_headers, is_dot_or_dotdot, closedir_error,
        closedir_warn, opendir_error, opendir_warn, readdir_error,
        readdir_warn): Remove decls.
        (get_directory_contents): New off_t arg.
        (addname): Now returns struct name *.

        * src/tar.h, tests/genfile.c: Fix comments.

        * src/create.c: Include hash.h.
        (gnu_list_name): Remove decl.
        (struct link): Remove "next" member.
        (linklist): Remove.
        (start_header): Say "leading `FOO'" rather than "`FOO' prefix" for
        consistency with other diagnostics.
        (deal_with_sparse): Check for I/O error when closing the file.
        (create_archive): Do not allocate an array of size PATH_MAX, as
        PATH_MAX might be (size_t) -1.  Instead, allocate an array with
        the size that's needed.
        (hash_link, compare_links): New functions.
        (dump_file): Do not exhaust open file descriptors when descending
        deeply into a directory, by using savedir rather than
        opendir/readdir.  Do not zero-fill the name buffer unnecessarily.
        Hash the set of links already created, instead of using a linked
        list.  Fix some bugs in outputting sparse files which caused the
        sparse tables to be incorrect.  When a file unexpectedly shrinks,
        output zeros rather than garbage.  Do not allocate an array of
        size PATH_MAX, as PATH_MAX might be (size_t) -1.  Instead,
        allocate an array with the size that's needed.

        * src/incremen.c: Include hash.h.
        (struct directory): Remove "next", "dir_text".  Change "name" to
        be char[1] with struct hack, not const char *.  Add "found".
        (directory_list): Remove.  Replaced by directory_table.
        (directory_table): New var.
        (nfs_string): Renamed from nfs.
        (hash_directory, compare_directories): New functions.
        (note_directory): Now returns struct directory *.  First arg is
        now const pointer.  struct stat arg is now dev_t, ino_t, nfs.
        Remove text arg.  New "found" arg, basically corresponding to the
        old text arg not being null.  All callers changed.
        (note_directory, find_directory): Use hash table rather than
        linked list.
        (get_directory_contents): New arg "device".  Use savedir to do the
        hard work.  Save the nfs-ness of stat_data, since it might change
        under us.  Use note_directory instead of find_directory to save
        some work.  When adding an "A" record, do it with
        add_to_accumulator instead of cheating with strcat.
        (read_directory_file): Use "+" flag before device to indicate
        whether it was NFS.  Fix typo in checking for strtoul error.
        (write_directory_file_entry): New function.
        (write_directory_file): Use it, and use the hash routines to
        traverse the directory table.
        (gnu_restore): Use savedir rather than opendir/readdir.

        * src/tar.c: Include localedir.h, prepargs.h.
        (long_options): Now static.
        (long_options, usage, decode_options): -j is now short for
        --bzip2, and -I is now an alias for -T.
        (decode_options, main): argv is not const pointer now.
        (decode_options): Invoke prepend_default_options to support
        TAR_OPTIONS.  In diagnostic, mention the string that was the
        invalid blocking factor, tape length, group, owner, or record
        size.  --delete is no longer incompatible with -f -, undoing
        2000-01-07 change.
        (main): Invoke extract_finish at end of extraction.

        * src/rmt.c: Include localedir.h.

        following changes: Use @sc where appropriate.  Document the ranges of
        supported times more precisely.  Add Eggert to getdate authors.
        Document old Latin 12m/12pm tradition.  Remove list of alphabetic time
        zone names, as it wasn't correct and people shouldn't be relying on it
        anyway.  Relative items also account for non-DST adjustments.  Fix
        some misspellings.

        * lib/prepargs.c, lib/prepargs.h, tests/extrac04.sh: New file.

        * tests/ignfail.sh: opendir -> savedir in diagnostics.

        * tests/preset.in: Set LANGUAGE to the empty string, for some
        brain damaged host.

        glibc 2.1.95.

2000-10-17  Paul Eggert  <eggert@twinsun.com>

        * lib/human.c (<limits.h>): Do not include; human.h does it if needed.
        (CHAR_BIT): Remove.

        * lib/human.h (<limits.h>): Include if HAVE_LIMITS_H.
        (CHAR_BIT): Define if not defined.

2000-09-09  Paul Eggert  <eggert@twinsun.com>

        * lib/xalloc.h (xalloc_msg_memory_exhausted):
        change to array from char *.

2000-08-06  Paul Eggert  <eggert@twinsun.com>

        * m4/mbstate_t.m4: Define mbstate_t to be int, not char, for
        compatibility with glibc 2.1.3 strftime.c.

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

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

        * lib/quotearg.c: Add support for more than one preallocated slot.

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

        * lib/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.

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

        * lib/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
        some GCC installations, and this configuration error is likely to be
        common.

2000-07-22  Paul Eggert  <eggert@twinsun.com>

        * lib/quotearg.c:
        When the system forces us to redefine mbstate_t, shadow its mbsinit
        function.  From Bruno Haible.

2000-07-14  Paul Eggert  <eggert@twinsun.com>

        * lib/xmalloc.c: Simplify exhausted message.

        * lib/quotearg.c:
        (quoting_style_args, quoting_style_vals, quotearg_buffer_restyled):
        Add support for clocale_quoting_style, undoing previous change to
        locale_quoting_style.

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

        * lib/quotearg.c:
        <wchar.h>: Include only if HAVE_MBRTOWC && 1 < MB_LEN_MAX,
        since otherwise we don't need it.
        (MB_CUR_MAX): Redefine to 1 if ! (HAVE_MBRTOWC && 1 < MB_LEN_MAX),
        since we don't do multibytes in that case.
        (quotearg_buffer_restyled): If a unibyte locale, don't bother to
        invoke multibyte primitives.

        * m4/mbstate_t.m4 (AC_MBSTATE_T):
        Renamed from AC_MBSTATE_T_OBJECT.  All uses changed.
        Change from a two-part test, which defines both HAVE_MBSTATE_T_OBJECT
        and mbstate_t, to a single-part test that simply defines mbstate_t.

        * lib/quotearg.c (mbrtowc): Do not use HAVE_WCHAR_H in the definition.
        Use defined mbstate_t, not HAVE_MBSTATE_T_OBJECT,
        to decide whether to define the BeOS workaround macro;
        this adjusts to the change to AC_MBSTATE_T.

        * m4/strerror_r.m4: New file.

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

        * lib/quotearg.c: Use double-quote to quote.

        * lib/quotearg.c (N_): New macro.
        (gettext_default): New function.
        (quotearg_buffer_restyled): Use gettext_default ("{LEFT QUOTATION MARK}",
        "\"") for left quote, and gettext_default ("{RIGHT QUOTATION MARK}", "\"")
        for right quote.

        * lib/quotearg.c (struct quoting_options):
        Simplify quote_these_too dimension.
        From Bruno Haible  <haible@clisp.cons.org>.

        * m4/mbstate_t.m4 (AC_MBSTATE_T_OBJECT):
        Test for mbstate_t only if the test
        for an object-type mbstate_t fails.

        * lib/quotearg.c (mbrtowc): Declare returned type, since BeOS doesn't.

2000-07-03  Paul Eggert  <eggert@twinsun.com>

        * m4/mbstate_t.m4 (AC_MBSTATE_T_OBJECT): Port to autoconf 2.13.
        Add AC_CHECK_HEADERS(stdlib.h), since we use HAVE_STDLIB_H.

        * lib/quotearg.c (mbrtowc):
        Assign to *pwc, and return 1 only if result is nonzero.
        (iswprint): Define to ISPRINT if we are substituting our own mbrtowc.

2000-07-02  Paul Eggert  <eggert@twinsun.com>

        * lib/quotearg.c (mbstate_t):
        Do not define; it should be defined with AC_CHECK_TYPE.

2000-06-26  Paul Eggert  <eggert@twinsun.com>

        * m4/mbstate_t.m4: Include stdio.h before wchar.h, to work around
        a bug in glibc 2.1.3.

        * lib/xmalloc.c: Fix inaccorate comment for xrealloc.

2000-06-19  Paul Eggert  <eggert@twinsun.com>

        Reported by Tom Tromey.

2000-06-15  Paul Eggert  <eggert@twinsun.com>

        (human_readable_inexact): Apply rounding style even when printing
        approximate values.

        indicator, not before.

2000-05-31  Paul Eggert  <eggert@twinsun.com>

        * m4/largefile.m4: Rewrite so that we don't need to run getconf,
        and thus don't need AC_CANONICAL_HOST.

        (AC_SYS_LARGEFILE_FLAGS, AC_SYS_LARGEFILE_SPACE_APPEND): Remove.
        (AC_SYS_LARGEFILE_TEST_INCLUDES): New macro.
        (AC_SYS_LARGEFILE_MACRO_VALUE): Change arguments from
        CODE-TO-SET-DEFAULT to VALUE, INCLUDES, FUNCTION-BODY.  All uses
        changed.  Instead of inspecting the output of getconf, try to
        compile the test program without and with the macro definition.
        (AC_SYS_LARGEFILE): Do not require AC_CANONICAL_HOST or check for
        getconf.  Instead, check for the needed flags by compiling test
        programs.

        * configure.in (AC_CANONICAL_HOST): Remove; the largefile stuff no
        longer needs it.
        * config.guess, config.sub: Remove these files, for similar reasons.

        * m4/largefile.m4 (AC_SYS_LARGEFILE): Define _XOPEN_SOURCE to be
        500, instead of _GNU_SOURCE to be 1, to work around glibc 2.1.3

        _GNU_SOURCE.

2000-05-02  Paul Eggert  <eggert@twinsun.com>

        * m4/largefile.m4 (AC_SYS_LARGEFILE):
        Define _GNU_SOURCE if this is needed to make
        ftello visible (e.g. glibc 2.1.3).  Use compile-time test, rather than
        inspecting host and OS, to decide whether to define _LARGEFILE_SOURCE.

        * lib/quotearg.c (mbrtowc, mbstat_t):
        Add definitions if !HAVE_MBSTATE_T_OBJECT.
        (<wctype.h>): Include if HAVE_WCTYPE_H.

        Don't use -n32 on IRIX if the installer said

        OLD_CTIME.

        (for consistency).  Member year changed from int to textint.  All
        uses changed.

        members.
        (tID): Removed; not used.

        tUNUMBER, tYEAR_UNIT, tZONE, o_merid): Now of type <intval>.
        (tSNUMBER, tUNUMBER): Now of type <textintval>.
        (date, number, to_year): Use width of number in digits, not its
        value, to determine whether it's a 2-digit year, or a 2-digit
        time.
        (yylex): Store number of digits of numeric tokens.  Return '?' for
        unknown identifiers, rather than (unused) tID.

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

        Do not quote alert, backslash, formfeed,

        (maybe_backup_file): Report "stat" for stat errors.
        (maybe_backup_file, chdir_do):
        Quote arbitrary strings in diagnostics.
        (maybe_backup_file, undo_last_backup):
        Don't assume that gettext preserves errno.
        (call_arg_error, call_arg_fatal, call_arg_warn,
        chdir_fatal, close_error, closedir_error, exec_fatal, mkfifo_error,
        mknod_error, open_error, open_fatal, open_warn, opendir_error,
        opendir_warn, read_error, read_fatal, readdir_error, readdir_warn,
        readlink_error, readlink_warn, seek_error, seek_warn, stat_error,
        stat_warn, truncate_error, truncate_warn, unlink_error, waitpid_error,
        write_error, write_fatal, xfork, xpipe, quote_n, quote): New functions.

        * src/system.h (__attribute__): New macro.
        (O_NDELAY, O_NONBLOCK, O_APPEND): Remove.
        (S_ISDOOR): New macro.
        (closedir): New macro, if CLOSEDIR_VOID.

        * src/rmt.c, src/rtapelib.c (decode_oflag):
        O_APPEND might not be defined.

        * src/list.c: (read_and, list_archive):
        Quote arbitrary strings in diagnostics.
        (from_header): Use locale_quoting_style to quote diagnostics.
        (print_header, print_for_mkdir): Quote with quotearg, not quote_copy_string.

        * src/rmt.h (REM_BIAS): Increase from 128 to (1 << 30).

        * src/Makefile.am: Use ## for copyright comments.

        * src/extract.c (<quotearg.h>): New include.
        (enum permstatus): New enum.
        (struct delayed_set_stat): file_name is now at end of buffer, to avoid
        two mallocs.  New members file_name_len, invert_permissions, permstatus.
        (extr_init): Remove hack that silently adjusted newdir_umask.
        (set_mode, set_stat): New args invert_permissions, permstatus, typeflag.
        Use these args to decide whether and how to set modes.
        (set_mode, set_stat, prepare_to_extract, extract_sparse_file, extract_archive):
        Don't assume that gettext preserves errno.
        (set_stat): Remove arg symlink_flag; subsumed by typeflag.
        (delay_set_stat, repair_delayed_set_stat): New functions.
        (make_directories): Avoid mkdir where last part of path is "..".
        Create a struct delayed_set_stat for each directory made.
        (prepare_to_extract): Renamed from unlink_destination, and
        return 0 immediately if to_stdout_option; all callers changed.
        (maybe_recoverable): New parameter interdir_made.
        Add support for --overwrite.
        (extract_sparse_file, extract_archive):
        Quote arbitrary strings in diagnostics.
        (extract_archive): By default, warn about ".." in member names, and skip them.
        Don't open files with O_NONBLOCK or O_APPEND.
        Open with O_TRUNC only if --overwrite; otherwise, use O_EXCL to avoid
        overwriting them.  Pass only rwxrwxrwx permissions to `open' and `mkdir',
        minus the current umask.  Keep track of intermediate directories made,
        to avoid looping when making x/../x when x doesn't exist; the
        earlier code solved this in a different way that didn't fit well
        into the new scheme.  Don't extract permissions onto existing
        directories unless --overwrite is given.  Do not add -wx------
        permissions to new directories permanently; just do it temporarily.
        Remove no-longer-needed hack with MSDOS and directory time stamps.
        (apply_delayed_set_stat): New argument specifies which directories to
        fix statuses of.  Do not wait until the end of extraction to fix
        statuses; instead, fix a directory's status once we exit that directory.
        This requires less memory and does the right thing in some cases
        where the old method didn't.
        (fatal_exit): New function.

        * src/incremen.c (<quotearg.h>): New include.
        (get_directory_contents, gnu_restore):
        Check for readdir and closedir errors.
        (get_directory_contents, read_directory_file, gnu_restore):
        Quote arbitrary strings in diagnostics.
        (get_directory_contents, read_directory_file, write_directory_file):
        Don't assume that gettext preserves errno.

        * src/create.c (<quotearg.h>): New include.
        (start_header): Use `member names' to refer to archive member names, not
        `archive names'.  Warn about `..' in member names.
        (finish_sparse_file, dump_file):
        Quote arbitrary strings in diagnostics.
        (finish_sparse_file, dump_file):
        Don't assume that gettext preserves errno.
        (dump_file): Don't use `access' to determine whether a directory is readable;
        this isn't reliable if tar is setuid.  Use `opendir' instead.
        Check for readdir and closedir failures.
        Don't dump sockets as if they were fifos; just warn and skip.

        * src/delete.c (move_archive):
        Don't report fatal error merely because sizes don't fit
        into struct mtop values; fall back on lseek instead.
        Say `Cannot' uniformly, instead of `Could not' sometimes and `Cannot' others.
        Say `reposition' instead of `re-position'.
        (delete_archive_members):
        Set archive to STDOUT_FILENO before outputting trailing buffer.

        * src/compare.c (<quotearg.h>): New include.
        (diff_init): Use `Cannot' uniformly, instead of `Could not' sometimes
        and `Cannot' others.
        (report_difference, diff_archive):
        Quote arbitrary strings in diagnostics.
        (process_rawdata, diff_sparse_files, get_stat_data, diff_archive, seek_warn):
        Don't assume that gettext preserves errno.
        (diff_archive): Don't open regular files with O_NONBLOCK.
        Preserve access times of files if --atime.

        * src/common.h (FATAL_ERROR): Use new fatal_exit function to exit.
        (FATAL_ERROR, USAGE): Don't return 0.
        (enum old files): New enum.
        (old_files_option): New variable, replacing keep_old_files_option and
        unlink_first_option.
        (apply_delayed_set_stat): Now takes char const * param.
        (fatal_exit, contains_dot_dot, chdir_fatal, close_error,
        closedir_error, exec_fatal, mkfifo_error, mknod_error, open_error,
        open_fatal, open_warn, opendir_error, opendir_warn, read_error,
        read_fatal, readdir_error, readdir_warn, readlink_error,
        readlink_warn, seek_error, seek_warn, stat_error, stat_warn,
        truncate_error, truncate_warn, unlink_error, waitpid_error,
        write_error, write_fatal, xfork, xpipe, quote, quote_n): New decls.

        * src/buffer.c:
        (xclose, xdup2, child_open_for_compress, child_open_for_uncompress,
        archive_write_error, archive_read_error, flush_archive, close_archive,
        init_volume_number, new_volume):
        Don't assume that gettext preserves errno.

        (xdup2): Don't report errno if dup returns an unexpected nonnegative value.
        (open_archive): Reject multivolume verify attempts a bit earlier.
        Rename local variable `access', in case it's defined by system header.

        (open_archive, backspace_output): Use `Cannot' uniformly, instead of
        `Could not' sometimes and `Cannot' others.

        (open_archive, flush_read, flush_archive, close_archive, new_volume):
        Quote arbitrary strings in diagnostics.

        (read_error): Set archive to STDOUT_FILENO temporarily when writing
        archive buffer.

        (init_volume_number): Check for input and output errors in volno_file.

        (new_volume): Use new fatal_exit function to exit, and new xfork
        function to fork.

        * Makefile.am (ACINCLUDE_INPUTS): Add $(M4DIR)/c-bs-a.m4.

        * doc/tar.texi: Add --overwrite.
        --absolute-names rejects ".." in names.

        * lib/quotearg.c: Add support for multibyte characters.
        (ISGRAPH): Remove.
        (ISPRINT): New macro.
        (<wchar.h>): Include if HAVE_MBRTOWC && HAVE_WCHAR_H.
        (isprint, mbrtowc, mbsinit, mbstate_t): New macros,
        defined if ! (HAVE_MBRTOWC && HAVE_WCHAR_H).
        (quotearg_buffer_restyled): New function, with most of the old
        quotearg_buffer's contents.
        Major rewrite to support multibyte characters.
        (quotearg_buffer): Now just calls quotearg_buffer_restyled.

        * m4/c-bs-a.m4: New file.

        * lib/Makefile.am: Use ## for copyright notice.

        * scripts/Makefile.am: Use ## on copyright notice.

        * doc/Makefile.am:
        ($(srcdir)/tar.info, tar.dvi): We now use texinfo 4.0.

1999-12-05  Paul Eggert  <eggert@twinsun.com>

1999-12-05  Dale Worley  <worley@ariadne.com>

        * src/compare.c (<utime.h>, struct utimbuf): Add.
        (diff_archive): Restore access times if --atime.
        * doc/tar.texi: Explain that --atime also preserves modification time.

1999-12-04  Gerhard Poul  <gpoul@gnu.org>

        * ABOUT-NLS: Update to latest version from ftp.gnu.org.
        * BACKLOG, TODO: Remove.
        * Makefile.am (all-local, BABYL, dist-zoo, id, ID): Remove.
        * README: Bring up to date.

1999-12-03  Paul Eggert  <eggert@twinsun.com>

        * NEWS, configure.in (AM_INIT_AUTOMAKE): Version 1.13.15.

        * src/compare.c (diff_archive):
        Do not set errno to EPIPE; we no longer use perror.

        * src/create.c (dump_file):
        If a parent directory said that a file should be there but it is
        absent, diagnose it as being removed in the meantime.
        Do not pass meaningless errno to ERROR when reporting that the
        file changed as we read it.
        Report that a file changed if its ctime changes; this is more
        sensitive than mtime+size, and more accurate.

        * src/incremen.c (enum children): New type.
        (struct directory): Change old char allnew member to new enum children
        children member.
        All uses changed.
        (get_directory_contents): When doing an incremental dump that does
        not cross filesystem boundaries, dump the mount points, even though
        they are in a different filesystem.  This is for convenience when
        restoring, and for consistency with non-incremental dumps.
        This requires a 3-way flag for keeping track of which children we want,
        so we use enum children rather than boolean.

        * src/open3.c (modes): Remove.
        (open3): Remove unportable assumptions about flag encodings.
        Use `stat' instead of `access' for testing file existence,
        to avoid problems with setuid programs.

        * src/names.c (name_next): If file names are given both in the
        command line (e.g. via -C) and in a file (via -T), do not
        ignore the command-line names.

        * m4/uintmax_t.m4: Backport to autoconf 2.13.

        * doc/tar.texi: Clarify getdate authorship.

1999-11-23  Paul Eggert  <eggert@twinsun.com>

        * lib/Makefile.am (DISTCLEANFILES): New macro.

        * configure.in (tar_fnmatch_hin):
        Remove; it runs afoul of a bug in autoconf 2.13.
        Instead, always link fnmatch.h to some file, even if it's a throwaway.

1999-11-19  Paul Eggert  <eggert@twinsun.com>

        * m4/largefile.m4: Update serial.

1999-11-18  Paul Eggert  <eggert@twinsun.com>

        * m4/largefile.m4 (AC_SYS_LARGEFILE_FLAGS): Work around a bug in
        the QNX shell, which doesn't propagate exit status of failed
        commands inside shell assignments.

        (tar_cv_path_RSH): Prefer a non-symlink rsh to a symlink one,
        for AIX crossbuilds.

        * doc/tar.texi: New node create options for --ignore-failed-read.
        Remove unused version control symbols.
        Modernize texinfo usage.

        * src/tar.c (usage): Add examples.

        * m4/fnmatch.m4 (AC_FUNC_FNMATCH):

        * src/common.h (collect_and_sort_names): New decl.

        * src/list.c (from_header):
        Handle 32-bit two's complement negative time stamps
        even if the leading octal digit is 2 or 3.

        * src/extract.c (set_stat): Remove duplicate code.

        * src/create.c (to_chars): Remove trailing newline from warning.
        (dump_file): Ignore doors.

        Remove old NeXT dirent problems, or AIX valloc problems.
        Remove old union wait advice, and old %lld advice.
        Remove advice about FreeBSD 2.1.7, ISC 4.1mu, Ultrix `make'.

        * doc/tar.texi: Clarify documentation for portable file names.

        * configure.in (AM_WITH_DMALLOC): Remove.
        (ALL_LINGUAS): Add ja.

        * src/tar.c (decode_options):
        Invalid dates are now treated as (time_t) -1.
        Redo version message to conform to GNU standards.

        * src/create.c (dump_file):
        Fix typo: last two args to dump_file were interchanged.
        * src/update.c (update_archive): Likewise.

        * src/common.h (tartime): New decl.

        * src/list.c (tartime): Now extern.
        (read_and): Invalid headers cause errors, not warnings.

1999-10-03  Paul Eggert  <eggert@twinsun.com>

        * lib/getdate.y (__attribute__):
        Don't use if GCC claims to be before 2.8; this is
        needed for OPENStep 4.2 cc.  Also, don't use if strict ANSI.

1999-09-25  Paul Eggert  <eggert@twinsun.com>

        * lib/fnmatch.c, lib/fnmatch.hin: Merge changes from latest glibc.
        * lib/getopt.c, lib/getopt.h, lib/getopt1.c: Likewise.

        * tests/incremen.sh: Add yet another sleep.

1999-09-24  Paul Eggert  <eggert@twinsun.com>

        * NEWS: A read error now causes a nonzero exit status.

        * src/create.c (to_chars): Fix base-256 output.

        * src/buffer.c (write_error):
        Read error is an error, not just a warning.

1999-09-24  Paul Eggert  <eggert@twinsun.com>

        * NEWS, configure.in (AM_INIT_AUTOMAKE): Version 1.13.12.

        Use chdir_do to change into directory.
        Use deref_stat instead of stat.
        Use add_avoided_name to mark names to be avoided; the old method of
        setting a bit with the name caused all descendants of that name to
        be avoided, in some circumstances.

        * tests/incremen.sh: Remove unnecessary sleeps.

        * src/names.c (name_next): Go back to using plain chdir.
        (name_gather): Use chdir_arg to keep track of arguments to chdir.
        (addname): Likewise.
        (name_match): Use chdir_do to act on chdir args.
        (merge_sort): Moved here from incremen.c.
        (compare_names, add_hierarchy_to_namelist, collect_and_sort_names):
        Likewise.
        (name_expand): Remove.
        (name_from_list): Skip fake names.
        Use chdir_do to act on chdir args.
        (struct avoided_name): New struct.
        (avoided_names): New var.
        (add_avoided_name, is_avoided_name): New functions.

        * src/system.h (stat, lstat): Define in terms of statx on
        STX_HIDDEN && !_LARGE_FILES /* AIX */ hosts.
        (UCHAR_MAX): New macro.
        (TYPE_MAXIMUM): Cast to arg type, for types narrow than int.

        * m4/largefile.m4: Work around GCC 2.95.1 bug with HP-UX 10.20.

        (time_now): Remove.
        (get_directory_contents): Use deref_stat.
        Consider a subdirectory to be all new only if
        listed_incremental_option or if it its timestamp is newer than the
        cutoff.
        (add_hierarchy_to_namelist, merge_sort): Move to names.c.
        (read_directory_file): Now extern.  Do not set time_now.
        (write_directory_file): Renamed from write_dir_file.
        Use start_time instead of time_now.
        (compare_names, collect_and_sort_names): Move to names.c.

        (chdir_arg, chdir_do): New function.

        * src/compare.c (get_stat_data): Use deref_stat.

        * src/common.h (name_expand): Remove.

        * src/list.c (time): Declare if not defined.
        (base_64_digits): Moved here from create.c.
        (base64_map): Use UCHAR_MAX for size, not less-clear (unsigned char)
        -1.
        (read_and): Don't get time from header unless we need it now;
        as getting time can cause duplicate diagnostics if bogus.
        Remove "Hmm, " from diagnostic.
        Use "Skipping to next header" uniformly.
        (from_header): Renamed from from_chars.  All uses changed.
        Allow different forms for unportable 2's complement numbers.
        Don't check for extended forms when parsing checksums.
        Parse base-256 output.
        (gid_from_header): Renamed from gid_from_chars.  All uses changed.
        (major_from_header): Renamed from major_from_chars.  All uses changed.

        (tartime): New function, incorporating isotime.
        (isotime): Delete.

        (time): No need to declare.
        (now): Remove variable.
        (extr_init): Don't initialize `now'.
        Increment same_permissions_option and same_owner_option if we_are_root

        Dump hard links to symbolic names as links, not as separate
        symbolic links.

        * lib/fnmatch.c (strchrnul):
        Define to __strchrnul if _LIBC, to our own replacement otherwise.

        Modernize sample backup script.

        * THANKS: Martin Goik's email address has changed.

        even the checksum bytes.  Do not attempt to parse the checksum of
        a zero block.  Fix memory leak with long names and links.

        if the previous field overflows.

        * acinclude.m4 (AC_LFS_FLAGS):
        Don't use -mabi=n32 with GCC on IRIX 6.2; it's the default.
        (AC_LFS): -n32, -o32, and -n64 are CPPFLAGS, not CFLAGS.
        (jm_FUNC_MALLOC, jm_FUNC_REALLOC): New macros.

        * configure.in (jm_FUNC_MALLOC, jm_FUNC_REALLOC):
        New macros; needed for latest GNU xmalloc.c.

        * configure.in (AC_VALIDATE_CACHED_SYSTEM_TUPLE):
        Remove; it doesn't work that well
        with AC_CANONICAL_HOST.
        (fp_WITH_INCLUDED_MALLOC): Remove; we'll just use the system malloc.

        * Makefile.am (EXTRA_DIST): Remove AC-PATCHES, AM-PATCHES, BI-PATCHES.

        (AC_LFS_FLAGS): Simplify so that it only gets the flags;
        `no' means it failed.
        (AC_LFS_SPACE_APPEND, AC_LFS_MACRO_VALUE): New macros.
        (AC_LFS): Use them.  Set _FILE_OFFSET_BITS, _LARGEFILE_SOURCE, and
        _LARGE_FILES from LFS_CFLAGS, so that in the normal case we don't need
        to add anything to the command line (it's all in config.h).
        Put any extra -D and -I options into CPPFLAGS, the rest into CFLAGS.

1999-03-01  Paul Eggert  <eggert@twinsun.com>

        * NEWS, configure.in (AM_INIT_AUTOMAKE): Version 1.12.64006.

        * acinclude.m4 (AC_LFS_FLAGS): Port to AIX 4.2.

        * src/list.c: (gid_from_oct, major_from_oct, minor_from_oct,
        mode_from_oct, off_from_oct, size_from_oct, time_from_oct,
        uid_from_oct, uintmax_from_oct): Use TYPE_MAXIMUM instead of macros
        like OFF_MAX, which are not reliable
        (e.g. OFF_MAX in AIX 4.2 is incorrect).
        * src/system.h (GID_MAX, MAJOR_MAX, MINOR_MAX, MODE_MAX, OFF_MAX,
        SIZE_MAX, TIME_MAX,UID_MAX, UINTMAX_MAX):  Remove; no longer used.

        * src/incremen.c (get_directory_contents):
        Don't use statx if _LARGE_FILES; it doesn't work under AIX 4.2.
        Have statx depend on STX_HIDDEN, not AIX.

        * src/create.c (to_oct):
        New parameter substitute, giving a substitute value to use
        when the original value is out of range.  Do not append a space to the
        output; modern tars don't.  When a value is out of range, specify the
        maximum value, not the number of bits.
        (GID_NOBODY, UID_NOBODY): New macros.
        (gid_to_oct, uid_to_oct): Use them as substitutes.
        (finish_header): Do not assume that UINTMAX_TO_OCT appends a space.
        (dump_file): Check whether the file changed as we read it.

        * src/rmt.c (main): Remove suspicious AIX/386 code.

1999-02-19  Paul Eggert  <eggert@twinsun.com>

        * intl/localealias.c (read_alias_file): Don't assume that memcpy
        returns a type compatible with char *; it doesn't on SunOS
        4.1.4 with Sun cc, since <string.h> doesn't declare memcpy.

        * NEWS, configure.in (AM_INIT_AUTOMAKE): Version 1.12.64005.

        * src/tar.c (long_options, usage): Prefer --unbzip2 to --bunzip2.
        * doc/tar.texi: Add --bzip2, --unbzip2 options.

        * configure.in (AC_CANONICAL_HOST, AC_VALIDATE_CACHED_SYSTEM_TUPLE):
        Add.
        (AC_LINK_FILES): Omit; AM_GNU_GETTEXT now does this.
        (AC_OUTPUT): Omit munging of po/Makefile; AM_GNU_GETTEXT now does this.
        * acinclude.m4 (AM_WITH_NLS):
        Update to latest gettext version (serial 5).
        (AC_LFS_FLAGS): New macro
        (AC_LFS): Use it.  Append to CFLAGS, LDFLAGS, LDLIBS instead of
        working only with unset variables.  Append to CFLAGS, not CPPFLAGS.
        Work properly in cross-compilation scenario, by checking for getconf
        with AC_CHECK_TOOL and by ditching uname in favor of
        AC_CANONICAL_HOST and $host_os.  Add --disable-lfs option.

        * lib/getdate.y: Update to fileutils 4.0 getdate.y, with one patch:
        replace FORCE_ALLOCA_H with HAVE_ALLOCA_H.
        * lib/Makefile.am (AUTOMAKE_OPTIONS): Append ../src/ansi2knr,
        since getdate.y now uses ANSI code.

        * config.guess, config.sub: New files; taken from automake 1.4.

        * intl/Makefile.in, intl/VERSION, intl/bindtextdom.c,
        intl/cat-compat.c, intl/dcgettext.c, intl/dgettext.c,
        intl/explodename.c, intl/finddomain.c, intl/gettext.c,

        intl/loadmsgcat.c, intl/localealias.c, intl/textdomain.c:
        Update to GNU gettext 0.10.35, with patches as per GCC snapshot 990109.

        Cache failures, too.

        * src/tar.c (decode_options):
        Don't pass names longer than UNAME_FIELD_SIZE to
        uname_to_uid, as it messes up the cache.  Similarly for gname_to_uid.

        (move_archive): Don't assume mt_count is of type daddr_t.

1997-10-30  Paul Eggert  <eggert@twinsun.com>

        * configure.in (CPPFLAGS, LDFLAGS, LIBS):
        Set to appropriate values if large file support
        needs explicit enabling.

        ssize_t):
        New macros to configure.

        * acconfig.h (daddr_t, HAVE_INTTYPES_H, HAVE_ST_FSTYPE_STRING,
        major_t, minor_t, ssize_t): New macros.

        * src/arith.h (TARLONG_FORMAT):

        than long.  Convert other types using `long' primitives.
        When processing MTIOCTOP, do not try to pass resulting
        count back, since it won't work (it could be too large) and it's
        not expected anyway.

        (append_file) Use off_t, size_t, ssize_t when appropriate.  Remove

        diff_sparse_files, diff_archive):
        Use off_t, pid_t, size_t, ssize_t when appropriate.
        Remove now-useless casts.  Use unsigned long to print *_t types,
        except use STRINGIFY_BIGINT for off_t.

        Size arg is now size_t.

        (diff_sparse_files): Arg is now off_t.  Check for size_t overflow
