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>

        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.

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>

        instead of gettext.
        * src/tar.c: Likewise.
        * tests/genfile.c: Likewise.

        'after_symlinks'.
        (delay_set_stat): Initialize it to 0.
        (set_mode): New arg current_stat_info.  Use it (if nonnull) to avoid
        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.

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

        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

        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,

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.
        New option --recursion (the default) that is the inverse of
        --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.

        * lib/exclude.c (bool): Declare, perhaps by including stdbool.h.
        (<sys/types.h>): Include only if HAVE_SYS_TYPES_H.

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

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

        * lib/prepargs.c: Include <string.h>; required for C99 since
        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
        diagnostic for LONGINT_INVALID_SUFFIX_CHAR.

        * m4/Makefile.am (EXTRA_DIST): Add check-decl.m4, mbrtowc.m4.
        Remove inttypes_h.m4, largefile.m4, mktime.m4.

        * m4/inttypes_h.m4, m4/largefile.m4, m4/mktime.m4: Remove;

        * m4/error.m4: Upgrade to serial 2.

        * m4/fnmatch.m4 (jm_FUNC_FNMATCH): Upgrade to serial 4, but
        remove test for GNU C library.  It's not correct, as some
        older glibcs are buggy.

        * m4/getline.m4, m4/malloc.m4: Upgrade to serial 4.

        * m4/prereq.m4: Upgrade to serial 20, but then:

        * m4/utimes.m4: Upgrade to latest version (still "serial 3").

        * 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.

        * src/common.h (excluded_with_slash, excluded_without_slash):
        Remove, replacing by:

        (excluded_name): Now returns bool.

        * src/extract.c:
        (struct delayed_symlinks, extract_archive, apply_delayed_symlinks):
        Support hard links to symbolic links.

        (struct delayed_symlink): Remove 'names' member, replacing it with
        '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>.
        (FILESYSTEM_PREFIX_LEN, ISSLASH): Remove; now defined by dirname.h.

        --wildcards-match-slash.

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

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

        (OPTION_STRING, decode_options): Add -I, -y.  Currently these options
        just print error messages suggesting alternatives.

        (add_filtered_exclude): Remove.

        * tests/extrac04.sh (out): Remove
        directory/subdirectory/file1, as the new semantics for

        (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.

        * configure.in (HAVE_DECL_STRERROR_R): Remove our handwritten code.
        (AC_FUNC_STRERROR_R): Use this instead.

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

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

        * lib/prepargs.c (prepend_default_options):
        Don't use NULL, for portability.

        * m4/fnmatch.m4: Add "working" to message.

        * src/names.c: (_GNU_SOURCE): Remove; autoconf now does this.
        Include <hash.h>.
        (getpwuid, getgrgid): Declare only if system headers don't.
        (gid_to_gname): Don't invoke setgrent.
        (namelist): Now static, not global.
        (nametail): New var.  All uses of namelast changed to use
        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.
        (main): Update copyright date to 2000.

        * doc/getdate.texi: New file, taken from fileutils 4.0.27, with the
        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.

2000-10-20  Paul Eggert  <eggert@twinsun.com>

        * m4/fnmatch.m4: Mention the GNU C library.

2000-10-19  Paul Eggert  <eggert@twinsun.com>

        * m4/fnmatch.m4: Add a couple more test cases to catch bugs in
        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/quotearg.c: From fileutils: rename ISASCII to IN_CTYPE_DOMAIN.

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

        * lib/xmalloc.c: Memory exhausted -> memory exhausted

        * 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.h: Update copyright date; from Jim Meyering.

2000-07-13  Paul Eggert  <eggert@twinsun.com>

        * lib/quotearg.h (enum quoting style):
        New constant clocale_quoting_style.

        * 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 (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>

        inclusion of wctype.h to work around solaris2.6 namespace pollution.
        (ISPRINT): Likewise.
        Reported by Tom Tromey.

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

        approximate values.

        * lib/human.c: Avoid shadowing warnings.
        From Jim Meyering.

2000-06-14  Paul Eggert  <eggert@twinsun.com>

        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.

2000-05-03  Paul Eggert  <eggert@twinsun.com>

        * 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
        bug.  This avoids a clash when files like regex.c that define
        _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.

2000-04-05  Paul Eggert  <eggert@twinsun.com>

        * m4/largefile.m4 (AC_SYS_LARGEFILE_FLAGS):
        Don't use -n32 on IRIX if the installer said
        otherwise.

        (textint): New typedef.
        (parser_control): Changed from struct parser_control to typedef
        (for consistency).  Member year changed from int to textint.  All
        uses changed.

        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,
        and vertical tab unnecessarily in shell quoting style.

2000-01-15  Paul Eggert  <eggert@twinsun.com>

        Return size instead of storing through pointer.
        All callers changed.
        (deal_with_sparse): Don't keep reading after read errors.
        (finish_sparse_file): Just abort if there is an internal error.
        (dump_file): Fix typo: stat_warn and stat_error were interchanged.
        Don't restore access times on directories during incremental dumps
        until after dealing with the directory.
        If ignoring failed reads, count closedir, read, and unknown
        file errors as warnings, not errors.
        Fix buffer overrun problem when dumping sparse files.

        * src/list.c (read_and):
        Invoke apply_nonancestor_delayed_set_stat on file names
        after handling them.
        (decode_mode): Remove; moved to misc.c.

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

        Plug memory leak.

        * tests/ignfail.sh: Adjust to new quoting scheme again.

2000-01-06  Paul Eggert  <eggert@twinsun.com>

1999-12-21  Machael Stone  <mstone@cs.loyola.edu>

        * README-alpha: New file.
        * README: New sections for gzip and bzip2, Solaris.
        Remove mention of BACKLOG.

        * configure.in (AC_C_BACKSLASH_A): Add.
        (AC_CHECK_HEADERS): Add wchar.h.
        (AC_CHECK_FUNCS): Add mbrtowc.
        (AC_FUNC_CLOSEDIR_VOID): Add.

        * tests/Makefile.am (TESTS): Add delete02.sh.
        (POSTPONED_TESTS): Remove.
        (EXTRA_DIST): Remove $(POSTPONED_TESTS).

        * tests/preset.in:
        Set LC_ALL rather than LANGUAGE, LANG, and LC_MESSAGES.

        * tests/ignfail.sh (err): Adjust to new quoting scheme.

        * tests/delete02.sh: Fix typo: need to list archive2, not archive.

        * tests/extrac03.sh: Use -P option, so that .. doesn't get diagnosed.

        * src/tar.c ("quotearg.h"): New include.
        (usage): Now has __attribute__ ((noreturn)).
        (confirm): Report errno if we can't open tty.
        (confirm, decode_options):
        Quote arbitrary strings in diagnostics.
        (OVERWRITE_OPTION): New constant.

        * src/update.c (<quotearg.h>): New include.
        (append_file):
        Don't assume that gettext preserves errno.
        Quote arbitrary strings in diagnostics.
        Check for close error.

        * src/names.c (<quotearg.h>): New include.
        (name_init, name_next, name_close, names_notfound,
        collect_and_sort_names): Don't assume that gettext preserves
        errno.  Quote arbitrary strings in diagnostics.
        (excluded_name): Fix typo that caused empty patterns to be
        mishandled.

        * src/misc.c (<quotearg.h>): New include.
        (quote_copy_string): Quote only newline and backslash; the output is no
        longer meant for humans, and is locale-independent.
        (contains_dot_dot): New function.
        (remove_any_file): Don't use lstat; just rmdir the file and then use
        unlink if the rmdir fails because the file isn't a directory.

        (maybe_backup_file): Report "stat" for stat errors.
        (maybe_backup_file, chdir_do):
        Quote arbitrary strings in diagnostics.

        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.

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.

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

        * m4/largefile.m4: Update serial.

        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.

        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.

        (from_header): Renamed from from_chars.  All uses changed.

        (extr_init): Don't initialize `now'.

        (mode_to_chars): Don't use two's complement in GNU format or POSIX
        format.
        (dump_file): Interchange last two arguments. If TOP_LEVEL is negative,
        it means we have an incremental dump where we don't know whether this
        is a top-level call.
        Use deref_stat instead of statx / stat / lstat.
        Cast result of alloca.
        Check for dates if 0 < top_level, not if listed_incremental_option.
        Move multiple-link check after directory check.
        Do not dump avoided names.
        Dump hard links to symbolic names as links, not as separate
        symbolic links.
        start_header cannot return a null pointer, so don't test for it.

        but act on non-garbage bytes (instead of ignoring them).
        (new_volume): Use WARN for warnings.

        * doc/Makefile.am:

        Modernize sample backup script.

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

        permissions problems.

        Do not assume st_mode values contain only file types and mode bits.
        Check for mode changes and device number changes separately.

        * src/update.c (append_file):
        Open the file before statting it, to avoid a race.
        Complain about file shrinkage only when we reach EOF.

        * NEWS, configure.in (AM_INIT_AUTOMAKE): version 1.12.64009

        * acinclude.m4 (AC_LFS_FLAGS): Add support for IRIX 6.2 and later.
        (AC_LFS_SPACE_APPEND): Assume $2 is quoted properly; all callers
        changed.
        (AC_LFS): Simplify AIX revision number test.

1999-03-17  Paul Eggert  <eggert@twinsun.com>

        * NEWS, configure.in (AM_INIT_AUTOMAKE): version 1.12.64008

        * 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.

        * Makefile.am (EXTRA_DIST): Remove gmalloc.c.

1999-03-07  Paul Eggert  <eggert@twinsun.com>

        * NEWS, configure.in (AM_INIT_AUTOMAKE): Version 1.12.64007.

        * acinclude.m4 (AM_WITH_NLS): Port to Solaris 2.5.1,
        where bindtextdomain and gettext require -lintl.
        (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.

        * 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.

        * configure.in (AC_CANONICAL_HOST, AC_VALIDATE_CACHED_SYSTEM_TUPLE):
        Add.
        (AC_LINK_FILES): Omit; 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.

        * src/tar.c (decode_options):
        Don't pass names longer than UNAME_FIELD_SIZE to

        Use off_t, size_t when appropriate.  Remove now-useless casts.

        * src/system.h (mode_t): Remove; now done by autoconf.
        (ST_NBLOCKS): Do not overflow if st_size is near maximum.
        Return number of ST_NBLOCKSIZE-byte blocks,
        not number of 512-byte blocks;
        this also helps to avoid overflow.
        (st_blocks): Declare if needed.
        (ST_NBLOCKSIZE): New macro.
        (<limits.h>, <inttypes.h>): Include if available.

        appropriate.  Remove now-useless casts.  Use unsigned long to print
        *_t types, except use STRINGIFY_BIGINT for off_t.

        (find_new_file_size): 1st arg is now off_t*.
        (finish_sparse_file): Args now use off_t, not long.
        Check for lseek error.
        (create_archive, dump_file): Cast -1 to dev_t when necessary.
        (dump_file): Device arg is now dev_t.
        Avoid overflow when testing whether file has holes
        by using the new ST_NBLOCKSIZE macro.

        * src/incremen.c (struct accumulator, add_to_accumulator,
        get_directory_contents, add_hierarchy_to_namelist, gnu_restore):
        Use size_t for sizes.
        (struct directory, get_directory_contents, add_hierarchy_to_namelist):
        Use dev_t, ino_t for devices and inodes.
        (gnu_restore): Use off_t for file offsets.
        (struct directory): Use char for flags.  Add new flag `nfs'.
        (nfs): New constant
        (NFS_FILE_STAT): New macro.
        (note_directory): Accept struct stat * instead of
        device and inode number.  All callers changed.
        (note_directory, get_directory_contents):
        Use NFS_FILE_STAT to determine whether directory is an NFS directory.
        (write_dir_file): Cast time_t to unsigned long before printing as %lu.

        * src/common.h (record_size, struct name, struct sp_array,
        available_space_after):
        Use size_t for sizes.
        (save_sizeleft, save_totsize, current_block_ordinal, skip_file):
        Use off_t for file offsets.
        (struct name): dir_contents is now const char *, not char *.
        (dump_file, get_directory_contents): Use dev_t for devices.
        (to_oct): Remove decl.
        (GID_TO_OCT, MAJOR_TO_OCT, MINOR_TO_OCT, MODE_TO_OCT, SIZE_TO_OCT,
        UID_TO_OCT, UINTMAX_TO_OCT, OFF_TO_OCT, TIME_TO_OCT, STRINGIFY_BIGINT,
        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): New macros.
        (gid_to_oct, major_to_oct, minor_to_oct, mode_to_oct, off_to_oct,
        size_to_oct, time_to_oct, uid_to_oct, uintmax_to_oct,
        stringify_uintmax_t_backwards, 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): New decls.
        (print_for_mkdir): 2nd arg is now mode_t.
