2013-10-24  Paul Eggert  <eggert@cs.ucla.edu>

        build: fix bug where 'configure --with-posix-acls' disables ACLs

        Reported by Lars Wendler in
        <http://lists.gnu.org/archive/html/bug-tar/2013-10/msg00022.html>.
        * configure.ac (with_posix_acls): Fix typo.

2013-10-23  Paul Eggert  <eggert@cs.ucla.edu>

        Fix core dump on Solaris 10 when "." isn't readable.

        Reported by Peter Kruse in
        <http://lists.gnu.org/archive/html/bug-tar/2013-10/msg00017.html>.
        This doesn't fix all the Solaris 10 test failures, just the
        core dump.

2013-09-24  Sergey Poznyakoff  <gray@gnu.org.ua>

        Fix normalize_filename.

        The function did not take into account eventual -C options, which

2013-08-04  Sergey Poznyakoff  <gray@gnu.org.ua>

        Reduce memory consuption when handling the -T option.

        The commit cdb27293 made the -T option more flexible, but
        incurred a very considerable memory overhead by storing
        all file names in the argument array.  In case of very
        big file lists this caused tar to run out of memory.  This
        was reported by Christian Wetzel <wetzel@phoenix-pacs.de>
        on March 14, 2013
        (http://lists.gnu.org/archive/html/bug-tar/2013-03/msg00018.html).

        On the other hand, Michal Žeidl discovered that tar misfunctioned
        when given empty file lists or lists with the trailing newline
        misssing in the last entry.  This was reported by Pavel Raiskup
        on July 23
        (http://lists.gnu.org/archive/html/bug-tar/2013-07/msg00009.html
        and
        msg00010.html).

        This change fixes both issues.

        * src/common.h (name_add_file,request_stdin): New prototype.
        (more_options): New prototype.
        * src/names.c (NELT_FILE): New entry type.
        (name_elt) <file>: New union member.
        (name_add_file): New function.
        (read_name_from_file): New function, a rewrite of
        the same function from tar.c
        (read_next_name,copy_name): New static functions.
        (name_next_elt): Handle NELT_FILE entries.
        * src/tar.c (request_stdin): Make extern.
        (read_name_from_file,add_file_id)
        (update_argv): Removed.
        (parse_opt): Change handling of the -T option.
        (more_options): New function.

        testsuite: do not resist on file order in archive

        On my Fedora 19 box, the exclude08 & exclude11 tests failed before
        this fix.  The reason was that the directory traversing chosen the

        Inspired by a prototype by Nathan Stratton Treadway in
        <http://lists.gnu.org/archive/html/bug-tar/2013-01/msg00000.html>.
        * src/incremen.c (read_num): Rewrite by merging read_negative_num
        and read_unsigned_num.  Use strtosysint rather than rolling this
        stuff ourselves.  Change return type to bool.  All uses changed.

        (read_num, read_timespec, read_incr_db_2): Improve quality of
        diagnostics, e.g., by supplying byte offset of error.

        (read_num):

2012-12-23  Paul Eggert  <eggert@cs.ucla.edu>

        Fix some problems with negative and out-of-range integers.

        Original problem reported for HP-UX LVM v2.2 by Michael White in
        <http://lists.gnu.org/archive/html/bug-tar/2012-10/msg00000.html>.
        This patch fixes some other gotchas that I noticed.
        * gnulib.modules: Add extern-inline.
        * src/common.h: Use _GL_INLINE_HEADER_BEGIN,
        _GL_INLINE_HEADER_END.
        (COMMON_INLINE, max, min): New macros.
        (represent_uintmax, valid_timespec): New inline functions.
        (SYSINT_BUFSIZE): New constant.
        (sysinttostr, strtosysint, decode_timespec): New decls.
        * src/create.c (start_private_header): Silently bring the time_t
        value into range; it is now the caller's responsibility to deal
        with any overflow error.  Use uid 0 and gid 0 rather than the
        user's uid/gid, since the faked header isn't "owned" by the user
        and the uid/gid could in theory be out of range.  Leave major and
        minor zeroed.
        (FILL): Remove.
        (write_gnu_long_link): Let start_private_header zero things out.
        * src/create.c (write_gnu_long_link, write_extended):
        * src/xheader.c (xheader_write_global):
        Use start_time, not current time; no point hammering on the clock.
        * src/compare.c (diff_multivol): Check that offset, size are
        in range.
        * src/incremen.c (read_incr_db_01, write_directory_file_entry):
        Allow negative time_t, dev_t, and ino_t.
        * src/list.c (max): Remove (moved to common.h).
        (read_header): Check that size is in range.
        (from_header): Return intmax_t, not uintmax_t, to allow negative.
        All callers changed.  At compile time, check assumptions about
        intmax_t and uintmax_t.  Use bool for booleans.  Avoid overflow
        hassles on picky hosts.
        (mode_from_header): Last arg is now bool *, not unsigned *.
        All callers changed.
        (simple_print_header): Do not assume UID, GID fit in 'long'.
        * src/list.c (from_header):
        * src/xheader.c (out_of_range_header):
        Arg is now a plain minimum value, not minus minval converted to
        uintmax_t.  All callers changed.
        * src/misc.c (COMMON_INLINE): New macro.
        (sysinttostr, strtosysint, decode_timespec): New functions.
        * src/sparse.c (oldgnu_add_sparse, oldgnu_fixup_header)
        (star_fixup_header):
        Check for offset overflow.
        (decode_num): Clear errno before calling strtoumax.
        * src/tar.c (expand_pax_option): Don't discard nanoseconds.
        * src/xheader.c (assign_time_option): Allow negative time_t.
        (decode_record): Simplify, since out-of-range string is guaranteed
        to produce a value exceeding len_max.
        (xheader_read): Last arg is off_t, not size_t.
        Caller should diagnose negative arg, as needed.
        Check that it's in range.
        (enum decode_time_status): Remove.
        (_decode_time): Remove, folding into decode_time.
        (decode_time): Return bool, not enum decode_time_status.
        Rely on decode_timespec to do most of the work.
        (code_signed_num): New function.
        (code_num): Use it.
        (decode_signed_num): New function.
        (decode_num): Use it.
        (gid_coder, gid_decoder, uid_coder, uid_decoder,
        sparse_map_decoder)
        (sparse_map_decoder): Code and decode negative values.
        (sparse_map_decoder): Improve check for out-of-range values.
        * tests/time01.at: New file.
        * tests/Makefile.am (TESTSUITE_AT): Add it.
        * tests/testsuite.at: Include it.

2012-12-22  Paul Eggert  <eggert@cs.ucla.edu>

        Port use of mkdirat etc. to Solaris 10.

        * gnulib.modules (fchmodat, fchownat, fstatat, mkdirat, unlinkat):
        Add.  These were split out in gnulib, so we now need to request
        them separately.  mkdirat, for example, is not in Solaris 10.

2012-12-22  Paul Eggert  <eggert@cs.ucla.edu>

        Port ACL configuration to Solaris 10.

        file_has_acl_at):
        Now static.
        * src/common.h (rmt_command_option): Remove; unused.
        * src/tar.c (check_links_option, allocated_archive_names):
        Move decls here from common.h; these are now static.

        literals in a char * context.
        * src/xattrs.c, src/xattrs.h (xattrs_clear_setup):

        Fix creation of incremental archives when a subdirectory becomes
        a mountpoint.

        When used with --listed-incrfental and --one-file-system, tar
        was unable to cope with directories that had once been part of the
        dumped system and became separate mount points afterwards.
        The bug
        has been reported and a fix proposed by Nathan Stratton Treadway.

        effect,

        tar: don't assume O_NONBLOCK is benign on regular files

        On Data Migration Facility (DMF), High Peformance Storage System
        (HPSS),
        and presumably other file systems based on hierarchical storage,
        opening
        a regular file with O_NONBLOCK can cause later reads to fail with
        errno == EAGAIN.  We need the O_NONBLOCK to avoid some security
        races.
        Work around the problem by using fcntl to clear the O_NONBLOCK
        flag if I/O fails with that errno value.

        Run alternative decompression programs if the principal one is
        not available.

        Some compression programs are able to handle various compression
        formats
        (e.g. `gzip' can decompress files created by `compress', `xz'
        is able
        to handle lzma, etc.)  Tar tries to use such programs for
        decompression
        if the principal decompressor cannot be started.

        * src/buffer.c (compress_type): Swap ct_none and ct_tar.
        (archive_compression_type): New static variable.
        (zip_magic): Remove program and option fields.
        (zip_program): New structure and static.
        (compress_program): Remove macro.
        (find_zip_program): New static function.
        (first_decompress_program,next_decompress_program): New functions.
        (open_compressed_archive): Set archive_compression_type instead of
        use_compress_program_option.
        * src/common.h (first_decompress_program)
        (next_decompress_program): New functions.
        (WARN_DECOMPRESS_PROGRAM): New flag.
        (WARN_VERBOSE_WARNINGS): Include WARN_DECOMPRESS_PROGRAM.
        * src/warning.c (warning_args): Add "decompress-program".
        (warning_types): Add WARN_DECOMPRESS_PROGRAM.
        * src/system.c (run_decompress_program): New function.
        (sys_child_open_for_uncompress): Use run_decompress_program
        instead of calling execlp directly.

2010-11-02  Paul Eggert  <eggert@cs.ucla.edu>

        tests: fix some issues with signals, timestamps, "test" typo

        * tests/extrac17.at: Add --warning=no-timestamp, to avoid
        bogus warning due to NFS clock skew.
        * tests/remfiles01.at: Discard diagnostics that some shells
        generate about broken pipes.
        * tests/sigpipe.at: Likewise.
        * tests/remfiles01.at: Fix typo: "test $EC" was written where
        "test $EC -ne 0" was intended.

2010-11-01  Sergey Poznyakoff  <gray@gnu.org.ua>

        Fix extraction of device nodes.

2010-10-28  Paul Eggert  <eggert@cs.ucla.edu>

        tar: don't cross struct member boundaries with OLDGNU_MAGIC

        * src/create.c (write_gnu_long_link, start_header): Access
        header->buffer + offsetof (struct posix_header, magic), instead of
        header->header.magic, when reading or writing the OLDGNU_MAGIC
        pattern.  The code violates the C standard without this change,
        and GCC warns about this if fortify checking is enabled.  It's not
        a bug on traditional (i.e., non-debugging) platforms, but it does
        violate the C standard so it should be fixed.  Problem originally
        reported by John Emil Karlson in
        <http://lists.gnu.org/archive/html/bug-tar/2010-04/msg00023.html>.
        * src/list.c (decode_header): Likewise.

2010-10-28  Paul Eggert  <eggert@cs.ucla.edu>

        tests: port to sh variants that squirrel away file descriptors

        OpenBSD /bin/sh, and some other sh variants, squirrel away file
        descriptors before closing them.  For example, for "cat 3<&-" they
        first dup file descriptor 3 to a fd that is 10 or greater, then
        close 3 (because if "cat" had been a builtin command like ":" then
        they would have wanted to avoid the fork and restore the fd after
        ":" finished); and they treat ordinary (forking) commands the same
        as builtin commands.  This approach fails after "ulimit -n 10".
        Work around this deficiency by closing the file descriptors before
        invoking ulimit.  Problem reported by Christian Weisgerber in
        <http://lists.gnu.org/archive/html/bug-tar/2010-10/msg00041.html>;
        solution suggested by Jilles Tjoelker in
        <http://article.gmane.org/gmane.comp.shells.dash/415>.

        * tests/extrac11.at (scarce file descriptors): Close file
        descriptors before invoking ulimit -n.

        Transform file names when updating and appendig to archives.

        This complements 28e91b48.

        * src/common.h (transform_stat_info): New prototype.

        tests: port to Solaris diff

        * tests/extrac13.at: Don't assume that "diff -c" outputs nothing
        when there are no differences.  This is not true on Solaris,
        where it outputs "No differences encounted".

2010-10-27  Paul Eggert  <eggert@cs.ucla.edu>

        tar: fix -x --overwrite bug (no --dereference, ! O_NOFOLLOW)

        This bug was discovered on Solaris 8.  On older hosts lacking
        O_NOFOLLOW, tar -x --overwrite (without --dereference) follows
        symbolic links, causing the "extract over symlinks" test to fail.

        * src/extract.c (open_output_file): If O_NOFOLLOW is needed but
        does not work, check for a symlink separately.

2010-10-27  Paul Eggert  <eggert@cs.ucla.edu>

        tar: don't use "((" in shell scripts

        * tests/extrac11.at: Replace "((" with "( (" in shell scripts, as

        that "((" is not portable.

        Make sure name matching occurs before name transformation.

        The commit 9c194c99 altered that order.

        * src/list.c (transform_stat_info): New function.  Split off from
        decode_header.
        (read_and): Call transform_stat_info right before do_something,
        and after deciding if we should proceed with this member name,
        so that name matching occurs before name transformation.

        * tests/extrac17.at: New file.
        * tests/Makefile.am (TESTSUITE_AT): Add extrac17.at
        * tests/testsuite.at: Include extrac17.at.

2010-10-26  Paul Eggert  <eggert@cs.ucla.edu>

        tar: don't assume stdin is open when testing fd limits

        * tests/extrac11.at: Redirect stdin from /dev/null, in case
        the parent 'make' is running with stdin closed.

2010-10-26  Sergey Poznyakoff  <gray@gnu.org.ua>

        Further fixes in bootstrap.

        * bootstrap: Restore the default for gnulib_path

        * src/extract.c (extract_dir): Use mkdirat, not mkdir.
        * tests/extrac16.at: New file, to test for this bug.
        * tests/Makefile.am (TESTSUITE_AT): Add it.
        * tests/testsuite.at: Include it.

        This file is a placeholder. It will be replaced with the actual
        ChangeLog
        by make dist.  Run make ChangeLog if you wish to create it
        earlier.

        Version 1.24

        * configure.ac, NEWS: Version 1.24
        * bootstrap: Restore tar-specific code lost during last
        sync from gnulib (241b72ffad).
        * src/misc.c (chdir_do): Remove unused automatic variable.

2010-10-16  Paul Eggert  <eggert@cs.ucla.edu>

        tar: use more-accurate diagnostic when intermediate mkdir fails

        Without this change, if tar tried to extract a file A/B/C, noticed
        that A/B didn't exist, attempted to mkdir A/B, and the mkdir
        failed, it did not diagnose the mkdir failure, but simply reported
        the failure to open A/B/C.  This sometimes led to confusion
        because it wasn't clear what tar was trying to do, in particular
        that tar tried to mkdir A/B.  With this patch, tar issues two
        diagnostics in this case: one for A/B and the other for A/B/C.
        Problem reported by Hauke Laging in
        <http://lists.gnu.org/archive/html/bug-tar/2010-10/msg00020.html>.
        * gnulib.modules: Remove faccessat.
        * src/extract.c (make_directories): New arg INTERDIR_MADE.
        Diagnose mkdir failure.  Return 0 on success, nonzero on failure,
        as opposed to nonzero iff some directory was created.  All callers
        changed.  Simplify the code when mkdir fails, by checking whether
        the desired file exists unless errno==EEXIST: this is more robust.
        * tests/extrac15.at: New test, to check this.
        * tests/Makefile.am (TESTSUITE_AT): Add it.
        * tests/testsuite.at: Include it.

2010-10-16  Paul Eggert  <eggert@cs.ucla.edu>

        tests: port to NFS file servers with clock skew

        Several of the tests assumed that a newly created file cannot
        have a time stamp dated in the future.  This assumption is not
        true when files are served by a remote host whose clock is
        slightly in advance of ours.  Fix the problems that I observed
        when running "make check" a couple of times on such a server.

        * tests/backup01.at: Use --warning=no-timestamp to suppress
        clock-skew warnings.
        * tests/chtype.at, tests/comprec.at, tests/exclude06.at:
        * tests/extrac01.at, tests/extrac03.at, tests/extrac05.at:
        * tests/extrac06.at, tests/extrac08.at, tests/extrac13.at:
        * tests/extrac14.at, tests/incr01.at, tests/incr03.at,

        Likewise.

        gnulib: sync from latest gnulib, notably bootstrap and
        parse-datetime

        * bootstrap: Sync from gnulib.
        * doc/.gitignore: Rename getdate.texi to parse-datetime.texi.

        * doc/tar.texi (Top): Adjust to renaming of getdate to
        parse-datetime.
        * gnulib.modules: Likewise.  Also, remove ftruncate (now
        obsolete).
        And add inttostr (we missed this dependency).
        * src/tar.c: Include parse-datetime.h, not getdate.h.  All calls
        to get_date replaced with parse_datetime.

2010-09-24  Paul Eggert  <eggert@cs.ucla.edu>

        tar: -x -C symlink fix

        * src/misc.c (chdir_do): Don't use O_NOFOLLOW when opening the
        argument to -C.  This is for consistency with "tar -c -C FOO", and
        matches the new documentation.
        * tests/extrac14.at: New file.
        * tests/Makefile.am (TESTSUITE_AT): Add it.
        * tests/testsuite.at: Include it.

2010-09-24  Paul Eggert  <eggert@cs.ucla.edu>

        tar: --dereference consistency

        This closes another race condition, that occurs when overwriting a
        symlink with a regular file.
        * NEWS (--dereference consistency): New section.
        * doc/tar.texi (Option Summary): Describe new --deference
        behavior.
        (dereference): Likewise.  Remove discussion that I didn't follow,
        even before --dereference was changed.
        * src/common.h (deref_stat, set_file_atime): Adjust signatures.
        * src/compare.c (diff_file, diff_multivol): Respect
        open_read_flags
        instead of rolling our own flags.  This implements the new
        behavior
        for --dereference.
        (diff_file, diff_dumpdir): Likewise, for fstatat_flags.
        * src/create.c: Adjust to set_file_atime signature change.
        * src/extract.c (mark_after_links, file_newer_p, extract_dir):
        Likewise.
        * src/incremen.c (try_purge_directory): Likewise.
        * src/misc.c (maybe_backup_file): Likewise.
        * src/extract.c (file_newer_p): New arg STP.  All callers changed.
        (maybe_recoverable): New arg REGULAR.  All callers changed.
        Handle the case of overwriting a symlink with a regular file,
        when --overwrite is specified but --dereference is not.
        (open_output_file): Add O_CLOEXEC, O_NOCTTY, O_NONBLOCK for
        consistency with file creation.  Add O_NOFOLLOW if
        overwriting_old_files && ! dereference_option.
        * src/incremen.c (update_parent_directory): Use fstat, not
        fstatat;
        there's less to go wrong.
        * src/misc.c (deref_stat): Remove DEREF arg.  All callers changed.
        Instead, use fstatat_flags.
        (set_file_atime): Remove ATFLAG arg.  All callers changed.
        Instead, use fstatat_flags.
        * src/names.c, src/update.c: Adjust to deref_stat signature
        change.
        * src/tar.c (get_date_or_file): Use stat, not deref_stat, as this
        is not a file to be archived.
        * tests/Makefile.am (TESTSUITE_AT): Add extrac13.at.
        * tests/extrac13.at: New file.
        * tests/testsuite.at: Include it.

        tar: do not crash with --listed-incremental

        Problem reported by Frantisek Hanzlik in
        <https://bugzilla.redhat.com/635318> via Kamil Dudka in
        <http://lists.gnu.org/archive/html/bug-tar/2010-09/msg00066.html>.
        I don't understand this code either, but Sergey can take a look at
        this patch, and perhaps install a better one, when he has
        the time.
        * src/incremen.c (append_incremental_renames): Don't actually
        append
        anything to DIR if DIR is null.

        tar: prefer openat-style functions

        This change replaces traditional functions like 'open' with the
        POSIX.1-2008 functions like 'openat'.  Mostly this is an internal
        refactoring change, in preparation for further changes to close
        some races.
        * gnulib.modules: Add faccessat, linkat, mkfifoat, renameat,
        symlinkat.
        Remove save-cwd.
        * src/Makefile.am (tar_LDADD): Add $(LIB_EACCESS).
        * tests/Makefile.am (LDADD): Likewise.
        * src/common.h (chdir_fd): New extern var.
        * src/compare.c (diff_file, diff_multivol): Use openat instead
        of open.
        * src/create.c (create_archive, restore_parent_fd): Likewise.
        * src/extract.c (create_placeholder_file): Likewise.
        * src/names.c (collect_and_sort_names): Likewise.
        * src/update.c (append_file): Likewise.
        * src/compare.c (diff_symlink): Use readlinkat instead of
        readlink.
        * src/compare.c (diff_file): Use chdir_fd instead of AT_FDCWD.
        * src/create.c (subfile_open, dump_file0): Likewise.
        * src/extract.c (fd_chmod, fd_chown, fd_stat, set_stat):
        (repair_delayed_set_stat, apply_nonancestor_delayed_set_stat):
        Likewise.
        * src/extract.c (mark_after_links, file_newer_p, extract_dir):
        (extract_link, apply_delayed_links):
        Use fstatat rather than stat or lstat.
        * src/misc.c (maybe_backup_file, deref_stat): Likewise.
        * src/extract.c (make_directories): Use mkdirat rather than mkdir.
        Use faccessat rather than access.  This fixes a minor permissions
        bug when tar is running setuid (who would want to do that?!).
        (open_output_file): Use openat rather than open.
        In the process, this removes support for Masscomp's O_CTG files,
        which aren't compatible with openat's signature.  Masscomp!  Wow!
        That's a blast from the past.  As far as I know, that operating
        system hasn't been supported for more than 20 years.
        (extract_link, apply_delayed_links):
        Use linkat rather than link.
        (extract_symlink, apply_delayed_links):
        Use symlinkat rather than symlink.
        (extract_node): Use mknodat rather than mknod.
        (extract_fifo): Use mkfifoat rather than mkfifo.
        (apply_delayed_links): Use unlinkat rather than unlink or rmdir.
        * src/misc.c (safer_rmdir, remove_any_file): Likewise.
        * src/unlink.c (flush_deferred_unlinks): Likewise.
        * src/extract.c (rename_directory): Use renameat rather than
        rename.
        * src/misc.c (maybe_backup_file, undo_last_backup): Likewise.
        * src/misc.c: Don't include <save-cwd.h>; no longer needed now
        that we're using openat etc.
        (struct wd): Add member fd.  Remove members err and fd.  All uses
        changed.
        (CHDIR_CACHE_SIZE): New constant.
        (wdcache, wdcache_count, chdir_fd): New vars.
        (chdir_do): Use openat rather than save_cwd.  Keep the cache up
        to date.  This code won't scale well, but is good enough for now.
        * src/update.c (update_archive): Use openat + fdopendir +
        streamsavedir rather than savedir.

        This file is a placeholder. It will be replaced with the actual
        ChangeLog
        by make dist.  Run make ChangeLog if you wish to create it
        earlier.

        tar: add utimens.h includes

        * src/extract.c: Include <utimens.h>, needed for fdutimens

2010-09-18  Paul Eggert  <eggert@cs.ucla.edu>

        tar: switch to gnulib fdutimensat module

        * gnulib.modules: Add fdutimensat.
        * src/common.h (fd_utimensat): Remove decl.
        * src/extract.c (set_stat): Call fdutimensat, not fd_utimensat.
        * src/misc.c (set_file_atime): Likewise.
        (fd_utimensat): Remove.

2010-09-17  Paul Eggert  <eggert@cs.ucla.edu>

        tar: extract permissions for . last

        * src/common.h (must_be_dot_or_slash): New decl.
        * src/extract.c (mark_after_links): New function, taking code
        that used to be in create_placeholder_file.
        (create_placeholder_file): Use it.
        (delay_set_stat): Always delay setting status for . and /.
        * src/misc.c (must_be_dot_or_slash): Now extern.
        * tests/extrac12.at: New file.
        * tests/Makefile.am (TESTSUITE_AT): Add it.
        * tests/testsuite.at: Likewise.

2010-09-17  Paul Eggert  <eggert@cs.ucla.edu>

        tar: don't check for getdtablesize; use AC_CHECK_FUNCS_ONCE

        * configure.ac: Don't check for getdtablesize; no longer needed.
        Use AC_CHECK_FUNCS_ONCE rather than AC_CHECK_FUNCS, for
        efficiency.

        tar: extract symlink attributes, close some symlink-related races

        * NEWS: Describe symlink-extraction improvements.
        * src/extract.c (enum permstatus): Remove.
        (fchmod, fchown): Define dummy replacement macros if the system
        does not supply them.
        (implemented): New function.
        (struct delayed_set_stat): Remove members invert_permissions,
        permstatus.  They were too confusing, and tried to do too much
        in too-little space.  Instead, add members current_mode,
        current_mode_mask, interdir, atflag.  All users changed.
        (struct delayed_link): Add members mode, atime, mtime, to support
        platforms such as BSD where symlinks have these attributes.
        All users changed.
        (fd_chmod): Renamed from fdchmod.  New argument atflag.  Check for
        operation not supported at run-time, not at configure-time.  Put
        fd argument first.  All callers changed.
        (fd_chown): Likewise, renaming from fdchown.
        (fd_stat): Likewise, renaming from fdstat.
        (set_mode): Remove args stat_info, cur_info, invert_permissions,
        permstatus.  Add args mode, mode_mask, current_mode,
        current_mode_mask,
        atflag.  All callers changed.  Close some races.  Use an easier-to
        understand method for computing permissions.  Work around POSIX
        incompatibility in Linux fchmodat.  Support extraction of symlink
        modes, if the OS allows it.
        (set_stat): Remove args cur_info, invert_permissions, permstatus.
        Add args current_mode, current_mode_mask, interdir, atflag.
        All callers changed.  Close some races.  Support extraction of
        attributes on symlinks, if the OS allows it.
        (delay_set_stat): Remove args invert_permissions, permstatus.
        Add args current_mode, current_mode_mask, mode, atflag.
        The ST arg can be null now, indicating that it's an intermediate
        directory.  All callers changed.
        (repair_delayed_set_stat, apply_nonancestor_delayed_set_stat):
        Close some races.
        (extract_dir): Also be paranoid if only --same-permissions, due
        to semantics of setgid and setuid directories on some hosts.
        This closes a race on those hosts.  Simplify calculation of
        delay_set_stat arguments; the old code was truly strange and
        probably wrong in some border cases.
        (extract_dir, extract_file, extract_node, extract_fifo): Don't
        rely on
        unspecified behavior in mode arg of open, mknod, etc.  Instead,
        mask out those bits when creating the file, and add them later via
        fchmod or chmodat.
        (open_output_file): file_name is now const.  Add arg current_mode,
        current_mode_mask.  All callers changed.  When overwriting
        old files,
        refuse to overwrite something that is not a regular file, since
        we're extracting a regular file.
        (extract_file): Remove the FIXME comment.  Whatever the protection
        issues were, they should be fixed now.  As a result of all
        the other
        API changes, we now use fchmod etc. rather than chmod etc.,
        closing
        some races.
        (create_placeholder_file, apply_delayed_links): Record desired
        mode and times for symlinks, for OSes that support that.

        tar: tar -x without --incremental no longer sets atime again

        * src/extract.c (set_stat): Use UTIME_OMIT rather than UTIME_NOW.
        The UTIME_NOW was there only to emulate the previous behavior of
        using the current time, and the previous behavior was there only
        because before we started assuming POSIX.1-2008 there was no
        portable way to get the effect of UTIME_NOW.

        tar: another --atime-preserve race fix

        * src/common.h (set_file_atime): Add parentfd arg.
        * src/compare.c (diff_file): Use it.
        * src/create.c (dump_file0): Likewise.  This closes yet another
        race condition with symbolic links.
        * src/misc.c (set_file_atime): Add parentfd arg.

2010-09-16  Paul Eggert  <eggert@cs.ucla.edu>

        tar: --atime-preserve fixes for races etc.

        This patch fixes a race condition in the --atime-preserve=replace
        option, which might cause tar to improperly follow a symbolic
        link.

        It also drops the use of the _FIOSATIME ioctl of Solaris 2.x
        and later, which loses resolution on time stamps.  Modern Solaris
        systems support full-resolution time stamps in the kernel, and
        it's not worth the hassle of testing this call, useful only in
        no-longer-supported Solaris variants.

        Also, it undoes a change I recently introduced to the --compare
        option, which caused it to not follow symbolic links unless the
        --dereference option was also used.  Quite possibly this change is
        a good idea, but the old behavior was documented and the change
        should not have been installed casually.

        * configure.ac: Don't check for stropts.h and sys/filio.h.
        * gnulib.modules: Add futimens, utimensat.  Remove futimens.
        * src/common.h (fd_utimensat): New decl.
        * src/compare.c (diff_file, diff_multivol):
        Don't use open_read_flags: those are for --create only.
        * src/create.c (dump_file0): Adjust to set_file_atime changes.
        Pass fstatat_flags to set_file_atime, so that symbolic links are
        not followed inadvertantly.
        * src/extract.c: Don't include utimens.h.
        (set_stat): Use fd_utimensat ant UTIME_NOW rather than fdutimens.
        * src/misc.c: Don't include utimens.h, stropts.h, sys/filio.h.
        (fd_utimensat): New function.
        (set_file_atime): Use it.  New arg atflag, controlling symlink
        handling.  All callers changed.

2010-09-14  Paul Eggert  <eggert@cs.ucla.edu>

        * configure.ac: tar: close some race conditions when extracting

        * configure.ac: Check for fchmod and fchown.  Don't check
        for utimes.
        * src/extract.c (fdchmod, fdchown, fdstat): New functions.
        (set_mode, set_stat): New arg FD.  All callers changed.
        This avoids some race conditions between closing a regular file
        and setting its metadata, and it's a bit faster.

2010-09-13  Paul Eggert  <eggert@cs.ucla.edu>

        tar: don't worry about fdopendir closing its argument

        * NEWS: Don't mention dirfd; no longer needed.
        * gnulib.modules: Remove dirfd.
        * src/create.c (get_directory_entries): Remove the code dealing
        with dirfd failures, as the new fdopendir replacement doesn't
        close its argument so we don't need to call dirfd.  See
        <http://lists.gnu.org/archive/html/bug-gnulib/2010-09/msg00208.html>
        and gnulib commit 970c9038e4cca46e1b037ae0a6d574dfae6a7327.

        tar: live within system-supplied limits on file descriptors

        * NEWS: Note the change.  Mention dirfd and fdopendir.
        * gnulib.modules: Add dirfd and fdopendir.  The code was already
        using fdopendir; dirfd is a new need.
        * src/common.h (open_searchdir_flags, get_directory_entries):
        (subfile_open, restore_parent_fd, tar_stat_close): New decls.
        (check_exclusion_tags): Adjust signature to match code change.
        * src/create.c (IMPOSTOR_ERRNO): New constant.
        (check_exclusion_tags): First arg is now a struct tar_stat_info
        const *, not an fd.  All callers changed.
        (dump_regular_file, dump_file0): A zero fd represents an unused
        slot, so play it safe if the fd member is zero here.  A negative
        fd represents the negation of an errno value, so play it safe and
        do not assign -1 to fd merely because an open fails.
        (open_failure_recover, get_directory_entries, restore_parent_fd):
        (subfile_open): New functions.  These help to recover from file
        descriptor exhaustion.
        (dump_dir, dump_file0): Use them.
        (dump_file0): Use tar_stat_close instead of rolling our own close.
        * src/incremen.c (scan_directory): Use get_directory_entries,
        subfile_open, etc., to recover from file descriptor exhaustion.
        * src/names.c (add_hierarchy_to_namelist): Likewise.
        (collect_and_sort_names): A negative fd represents the negation
        of an errno value, so play it safe and do not assign -1 to fd.
        * src/tar.c (decode_options): Set open_searchdir_flags.
        Add O_CLOEXEC to all the open flags.
        (tar_stat_close): New function, which knows how to deal with
        new convention for directory streams and file descriptors.
        Diagnose 'close' failures.
        (tar_stat_destroy): Use it.
        * src/tar.h (struct tar_stat_info): New member dirstream.
        fd now has the negative of an errno value, not merely -1, if
        the file could not be opened, so that failures to reopen
        directories
        are better-diagnosed later.
        * tests/Makefile.am (TESTSUITE_AT): Add extrac11.at.
        * tests/testsuite.at: Likewise.
        * tests/extrac11.at: New file.

        tar: more reliable directory traversal when creating archives

        * NEWS: Document this.
        * gnulib.modules: Add openat, readlinkat.
        * src/common.h (open_read_flags, fstatat_flags): New global
        variables.
        (cachedir_file_p, dump_file, check_exclusion_tags,
        scan_directory):
        Adjust to new signatures, described below.
        (name_fill_directory): Remove.
        * src/compare.c (diff_file, diff_multivol): Use open_read_flags.
        * src/create.c (struct exclusion_tag): Exclusion predicates
        now take
        a file descriptor, not a file name.
        (add_exclusion_tag): Likewise.  All uses changed.
        (cachedir_file_p): Likewise.
        (check_exclusion_tags): The directory is now a file descriptor,
        not a file name.  All uses changed.  Use openat for better
        traversal.
        (file_dumpable_p): Arg is now a struct stat, not a struct
        tar_stat_info.  All uses changed.  Check the arg's file types too.
        (dump_dir0, dump_dir, dump_file0, dump_file): Omit top_level and
        parent_device args, since st->parent tells us that now.  All uses
        changed.
        (dump_dir): Likewise.  Also, omit fd arg for similar reasons.
        Apply fdsavedir to a dup of the file descriptor, since we need a
        file descriptor for openat etc. as well, and fdsavedir (perhaps
        unwisely) consumes its file descriptor when successful.
        Do not consume st->fd when successful; this simplifies the caller.
        (create_archive): Allocate a file descriptor when retraversing
        a directory, during incremental dumps.
        (dump_file0): Use fstatat, openat, and readlinkat for better
        traversal.
        When opening a file, use the result of fstat on the file
        descriptor
        rather than the fstatat on the directory entry, to avoid some race
        conditions.  No need to reopen the directory since we now
        no longer
        close it.  Change "did we open the file?" test from 0 <= fd to
        0 < fd since fd == 0 now represents uninitialized.
        (dump_file): Now accepts struct tar_stat_info describing parent,
        not parent_device.  Also, accept basename and fullname of entry.
        All uses changed.
        * src/incremen.c (update_parent_directory): Accept struct
        tar_stat_info for parent, not name.  All callers changed.
        Use fstatat for safer directory traversal.
        (procdir): Accept struct tar_stat_info, not struct stat and
        dev_t, for info about directory.  All callers changed.
        (scan_directory): Accept struct tar_stat_info, not name,
        device, and cmdline, for info about directory.  All callers
        changed.  Do not consume the file descriptor, since caller
        might need it.  Use fstatat and openat for safer directory
        traversal; also, use fstat after opening to double-check.
        (name_fill_directory): Remove.
        * src/names.c (add_hierarchy_to_namelist): Accept struct
        tar_stat_info instead of device and cmdline.  All callers changed.
        When descending into a subdirectory, use openat and fstat for
        safer directory traversal.
        (collect_and_sort_names): Use open and fstat for safer directory
        traversal.  Set up struct tar_stat_info for callee's new API.
        * src/tar.c (decode_options): Initialize open_read_flags
        and fstatat_flags.
        (tar_stat_destroy): Close st->fd if it is positive (not zero!).
        * src/tar.h (struct tar_stat_info): New members parent, fd.
        * src/update.c (update_archive): Adjust to dump_file's API change.
        * tests/filerem02.at: Ignore stderr since its contents now depend
        on the file system implementation.

        tar: remove lint discovered by Sun C compiler

        * src/common.h (WARN_ALL): Don't mask with 0xffffffff; on a 32-bit
        host, 0xffffffff is of type 'unsigned int', which makes WARN_ALL
        an unsigned int value that is too large to fit into an int, and
        the C standard says that this has undefined behavior.  The mask is
        not needed, so omit it.

        * src/tar.c (LOW_DENSITY_NUM, MID_DENSITY_NUM, HIGH_DENSITY_NUM):
        Restore these macros, undoing the previous change to this file.
        The macros are used after all, in some cases.  Sorry about that.

2010-09-03  Paul Eggert  <eggert@cs.ucla.edu>

        tar: remove unused macros

        * src/create.c (UINTMAX_TO_CHARS): Remove; no longer used.
        * src/tar.c (LOW_DENSITY_NUM, MID_DENSITY_NUM, HIGH_DENSITY_NUM):
        Likewise.
        * src/incremen.c (DIR_IS_NEW): Comment out; not used.
        Mark this with a FIXME, since it looks like it should be used.

2010-08-27  Sergey Poznyakoff  <gray@gnu.org.ua>

        Fix --remove-files in update/append mode.

        * src/update.c (update_archive): Call finish_deferred_unlinks when
        done.

        tar: avoid assumptions about root access and chmod -w in test
        cases

        * tests/extrac07.at, tests/extrac09.at, tests/listed03.at: Use
        AT_UNPRIVILEGED_PREREQ, since this test requires non-root
        privileges.
        * tests/extrac07.at: Don't use "chmod -w", as POSIX says it's not
        portable to start a chmod permissions-list with "-" as it may be
        confused with an option.  Use "chmod a-w" instead.

        (extract_archive): Restore the current directory after
        apply_nonancestor_delayed_set_stat has possibly changed it.
        * src/misc.c (chdir_current): New external var; this used to
        be the private static variable 'previous' inside chdir_dir.
        All uses changed.
        * tests/Makefile.am (TESTSUITE_AT): New test extrac10.at.
        * tests/extrac10.at: New file.

2010-08-25  Paul Eggert  <eggert@cs.ucla.edu>

        tar: optimize -c --sparse when file is entirely sparse

        * src/sparse.c (sparse_scan_file): If the file is entirely sparse,
        that is, if ST_NBLOCKS is zero, don't bother scanning for nonzero
        blocks.  Idea by Kit Westneat, communicated by Bernd Schubert in
        <http://lists.gnu.org/archive/html/bug-tar/2010-08/msg00038.html>.
        Also, omit unnecessary lseek at start of file.

2010-08-25  Paul Eggert  <eggert@cs.ucla.edu>

        tar: don't assume size of a sparse file chunk fits in size_t

        * src/tar.h (struct sp_array): Change numbytes from size_t
        to off_t.
        All uses changed.
        * scripts/xsparse.c (struct sp_array): Likewise.
        Include <stdint.h>, for SIZE_MAX.
        (expand_sparse): Don't try to allocate a buffer bigger than
        SIZE_MAX bytes.
        * src/common.h (SIZE_TO_CHARS, size_to_chars, SIZE_FROM_HEADER):

        Likewise.

2010-08-25  Paul Eggert  <eggert@cs.ucla.edu>

        tar: use ctime, not mtime, when checking placeholders

        * src/extract.c (struct delayed_link): Rename member mtime
        to ctime.
        All uses changed to use ctime rather than mtime.

2010-08-24  Paul Eggert  <eggert@cs.ucla.edu>

        tar: add comment to link04.at test

        * tests/link04.at: Add explanatory comment at head.

2010-08-24  Paul Eggert  <eggert@cs.ucla.edu>

        tar: fix 1.23 Solaris regression related to PRIV_SYS_LINKDIR

        The idea was suggested by Petr Sumbera in the thread starting
        here:
        http://lists.gnu.org/archive/html/bug-tar/2010-08/msg00000.html
        * src/extract.c (set_mode): Save the errno of the chmod that
        failed, for the benefit of chmod_error_details.  Do not bother
        retrying chmod unless the mode suggests setuid is the issue.
        (extract_archive): Remove redundant call to
        priv_set_remove_linkdir.
        * src/system.c: Include priv-set.h.
        (sys_spawn_shell, sys_child_open_for_compress):
        (sys_child_open_for_uncompress, sys_exec_command):
        (sys_exec_info_script, sys_exec_checkpoint_script):
        Invoke priv_set_restore_linkdir before execv or execlp, so that
        the subprocess has the same privileges that tar originally did.

2010-08-24  Paul Eggert  <eggert@cs.ucla.edu>

        tar: handle files that occur multiple times but have link count 1

        This patch was inspired by the following patch that addressed a
        similar problem in GNU coreutils du:
        http://git.savannah.gnu.org/gitweb/?p=coreutils.git;h=efe53cc72b599979ea292754ecfe8abf7c839d22
        * src/common.h (name_count): New decl.
        * src/create.c (trivial_link_count): New static var.
        (create_archive): Initialize it.
        (dump_hard_link, file_count_links): Use it, so that files with
        link count 1 are handled correctly when they are found multiple
        times.
        * src/names.c (allocated_entries): Renamed from allocated_names,
        since the identifier's name was misleading.  All uses changed.
        (entries): Renamed from names.  All uses changed.
        (scanned): Renamed from name_index.  All uses changed.
        (name_count): New var.
        (name_add_name): Increment it.
        * tests/link04.at: New file.
        * tests/testsuite.at: Add it.
        * tests/Makefile.am (TESTSUITE_AT): Likewise.

2010-08-23  Paul Eggert  <eggert@cs.ucla.edu>

        tar: use nlink_t for link counts

        * src/create.c (struct link): nlink is now of type nlink_t,
        not size_t.

2010-08-23  Paul Eggert  <eggert@cs.ucla.edu>

        tar: don't export names that aren't used elsewhere

        modules.
        (GID_TO_CHARS, MAJOR_TO_CHARS, MINOR_TO_CHARS, MODE_TO_CHARS):
        (UID_TO_CHARS, UINTMAX_TO_CHARS, UNAME_TO_CHARS, GNAME_TO_CHARS):
        Move to src/create.c, since no other module uses these.
        (GID_FROM_HEADER, MAJOR_FROM_HEADER, MINOR_FROM_HEADER):
        (MODE_FROM_HEADER, TIME_FROM_HEADER, UID_FROM_HEADER):

2010-08-20  Paul Eggert  <eggert@cs.ucla.edu>

        tar: change interdir_made from int to bool

        * src/extract.c (maybe_recoverable, create_placeholder_file):
        Change interdir_made from int * to bool *, since the flag has just
        two values 0 and 1.  All uses changed.  This does not affect tar's
        behavior.

2010-08-19  Paul Eggert  <eggert@cs.ucla.edu>

        tar: update licenses to latest versions from www.gnu.org

        formatting.
        * doc/fdl.texi: Update from GFDL 1.2 to 1.3.
        * doc/tar.texi: Adjust to new format of fdl.texi.  Omit trailing
        white space.

2010-07-18  Paul Eggert  <eggert@cs.ucla.edu>

2010-07-18  Paul R. Eggert  <eggert@cs.ucla.edu>

        tar: no need to report getcwd error if never using the result

        * src/misc.c (struct wd): Rename 'saved' to 'err', with new
        semantics.
        (chdir_arg, chdir_do): Adjust to new semantics.  Do not report an
        error merely because save_cwd fails; report an error only if
        save_cwd's result is needed later.
        * tests/extrac09.at: New file, to test for bug that was fixed.

        tar: go back to absolutifying filenames in normalize_filename
        for now

        * src/misc.c (normalize_filename): For now, go back to making
        filenames absolute, even though this causes 'tar' to fail when
        getcwd fails.  However, do not attempt to resolve ".." as this
        does not work with symlinks.  Also, do the right thing with
        leading file system prefixes and on hosts where // != /.

        /../, which can't be done reliably in the presence of symlinks.
        Don't reject valid names such as ".".
        (normalize_filename): Don't make it absolute; that way, we don't
        have to invoke xgetcwd which might fail.  Don't bother to realloc
        at the end, since that uses time and now saves little space.
        (chdir_do): Don't crash if xgetcwd fails.

        * src/names.c: Remove old-style declarations of getgrnam etc.
        All modern systems declare these, and it's not worth the hassle
        of ignoring the warnings on modern systems for old-style decls.

2010-05-17  Sergey Poznyakoff  <gray@gnu.org.ua>

        Bugfix.

        * src/incremen.c (make_directory): Retain the slash if it is the

        as the 2nd argument to tartime.
        * doc/tar.texi: Update.
        * NEWS: Update.

2010-03-27  Sergey Poznyakoff  <gray@gnu.org.ua>

        * tests/link02.at: Use `ln' instead of `link'.
        * tests/link03.at: Likewise.

2010-03-27  Sergey Poznyakoff  <gray@gnu.org.ua>

        Fix coredump.

        8f390db92fc. Reported by Ico Doornekamp <bug-tar@zevv.nl>.
        * NEWS: Update.

2010-03-20  Sergey Poznyakoff  <gray@gnu.org.ua>

        * NEWS: Update.

2010-03-17  Sergey Poznyakoff  <gray@gnu.org.ua>

        Fix --remove-files.

        Tar --remove-files relied on canonicalize_file_name,
        which replaces symlinks in file name components with
        the directories they point to. Due to this, tar
        effectively ignored existence of symbolic links and
        was unable to remove a directory that contained any
        (Alexander Kozlov <akozlov@nada.kth.se>, 2010-03-15).

        * gnulib.modules: Remove canonicalize.
        * src/misc.c (normalize_filename): Rewrite
        from scratch. The function operates only on
        its input string, it makes no attempt to test
        components for existence or to resolve symbolic
        links.
        * tests/Makefile.am (TESTSUITE_AT): Add remfiles03.at.
        * tests/testsuite.at: Likewise.
        * tests/remfiles03.at: New test case.

        Fix eventual memory override and fd exhaustion in create.c Both
        bugs reported by Kamil Dudka.

        * src/create.c (check_exclusion_tags): Do not keep
        pointer to a location within tagname: it may change
        after xrealloc. Use byte offset instead.
        (dump_file0): Close fd before returning without
        dumping the directory.

2010-03-02  Sergey Poznyakoff  <gray@gnu.org.ua>

        All callers updated.
        * src/buffer.c (try_new_volume): Allow for volumes split at the
        extended/ustar header boundary. This is against POSIX specs, but
        we must be able to read such archives anyway.

        * tests/multiv07.at: New test case.

        accumulated in xhdr->stk even if keyword_global_override_list
        is empty.
        (xheader_read): On unexpected EOF, report error instead of
        coredumping.
        (XHDR_PROTECTED, XHDR_GLOBAL): New defines.
        (struct xhdr_tab): Remove `protected' with `flags'. All uses

        * src/extract.c: Likewise.
        (extract_volhdr): Do not print "Reading <label>" statement,
        because
        it is inconsistent: it is not printed if the volume begins with a
        member continued from the previous volume.

        (format_default_settings): Use xasprintf.
        (parse_opt): Use *_PROGRAM defines instead of hardcoded
        program names.

2009-10-10  Sergey Poznyakoff  <gray@gnu.org.ua>

        Allow installers to specify alternative program names for
        compression programs.

        This adds --with-gzip, --with-bzip2 etc. switches to the
        configure, so that
        one can do, e.g. ./configure --with-bzip2=lbzip2 and have
        lbzip2 executed
        whenever user calls `tar --bzip2'.

        * acinclude.m4: New file.
        * configure.ac: Add TAR_COMPR_PROGRAM invocations for
        the supported compressors.
        * src/buffer.c (magic): Use *_COMPRESSOR defines instead
        of hardcoded program names.

        * src/suffix.c (compression_suffixes, nsuffixes): Mark as static.

2009-10-07  Sergey Poznyakoff  <gray@gnu.org.ua>

        Provide a way to explicitly set mtime for extended header
        ustar blocks.

        * src/tar.c (struct textual_date): ts is a copy of the structure,
        not a pointer to it. Date is a copy as well, hence the `const' is
        taken away.
        (get_date_or_file): Return 0/1 depending on success/failure.
        Copy timestamp to the `ts' member. Store a copy of the string
        in `date'.
        (report_textual_dates): Report only if verbose_option is set,
        but always free the list.
        (expand_pax_option): New function.

        expand_pax_option.

        exthdr.mtime or globexthdr.mtime option is set.
        * NEWS: Update
        * doc/tar.texi: Document the changes.

2009-10-07  Sergey Poznyakoff  <gray@gnu.org.ua>

        Use file's mtime as mtime for its extended header.

        This makes two pax archives binary equivalent if they
        have the same contents and care is taken to make extended
        headers otherwise reproducible, e.g. by using:

          --pax-option=exthdr.name=%d/PaxHeaders/%f,atime:=0

        Proposed by Michael D. Adams <mdmkolbe@gmail.com>.

        (dump_filed): top_level is bool.
        * src/incremen.c (update_parent_directory): Silently ignore

        Improve listed incremental dumps.

        directory twice and ensures the order of the directories
        in the resulting archive is the same, whatever their order

        get_directory_contents and scan_directory.
        (collect_and_sort_names): Allow at most one -C, before file name
        arguments.
        Read directory file after eventual changing to another directory.
        Avoid adding the same directory under different pathnames to
        the list.
        * src/tar.c: New option --level.

        * tests/incr03.at, tests/incr04.at, tests/listed01.at,
        tests/listed02.at, tests/rename01.at, tests/rename02.at,
        tests/rename03.at: Update for new tar behavior.

        Remember to mask out current umask before inverting permissions.
        (extract_dir): If the owner might change, or if the mode has

        * tests/Makefile.am, tests/testsuite.at: Add multiv05.at

2006-09-27  Sergey Poznyakoff  <gray@gnu.org.ua>

        * bootstrap: Use ${package} instead of hardcoding package name
        * doc/tar.texi: Minor fix
        * src/tar.c (doc0, doc1, initialize_argp_doc): Removed.  Rely on
        the new argp method instead.

2006-09-12  Sergey Poznyakoff  <gray@gnu.org.ua>

        * README: Fix a typo

2006-09-08  Paul Eggert  <eggert@cs.ucla.edu>

        Adjust to latest gnulib.
        * lib/.cvsignore: Add at-func.c, configmake.h, fchmodat.c,
        fcntl.h, fcntl_.h, inttypes_.h, lstat.c, lstat.h.
        * tests/testsuite.at (AT_TAR_MKHIER): Use install-sh -d
        rather than the no-longer-included mkinstalldirs.

2006-09-08  Sergey Poznyakoff  <gray@gnu.org.ua>

        * src/incremen.c (try_purge_directory): Initialize struct st.  Fix
        condition for selecting candidates for removal.
        * README-alpha: List texinfo among build prerequisites for the CVS
        version.

        * bootstrap (intl_files_to_remove): Do not remove m4/inttypes-h.m4
        and m4/inttypes-pri.m4

2006-08-11  Paul Eggert  <eggert@cs.ucla.edu>

        * bootstrap: Set XGETTEXT_OPTIONS to flag our printf-format functions,
        so that translators are warned about strings that are formats but
        don't look like formats.  This might help prevent core dumps.
        * configure.ac (AM_GNU_GETTEXT): Upgrade to need-formatstring-macros.
        Suggested by Eric Blake to avoid problems like
        <http://lists.gnu.org/archive/html/bug-coreutils/2006-07/msg00087.html>.
        (AM_GNU_GETTEXT_VERSION): Upgrade from 0.12.1 to 0.15.  The gettext
        manual says we should use the version number normally expected of
        maintainers, neither more nor less.

        * bootstrap (get_translations):
        Don't exclude ky.po; it is working again.

2006-08-09  Paul Eggert  <eggert@cs.ucla.edu>

        * bootstrap (get_translations):
        Don't exclude ja.po; it is working again.
        Don't remove all old .po files if we're merely updating one.
        * po/.cvsignore: Add Makevars.

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

        * src/tar.c: Work around limitation imposed by gettext 0.15
        by concatenating strings with "\v" after translation.
        (doc): Remove, splitting into:
        (doc0, doc1): New constants.
        (argp): Don't use doc; just initialize to NULL.
        (initialize_argp_doc): New function.
        (decode_options): Use it.

        * bootstrap: Redo po file retrieval to match Bison's method,
        since the translation project changed its index format.
        Don't use --assume-autoconf; it's now replaced
        by looking in configure.ac.
        (m4/codeset.m4, m4/intdiv.m4, m4/inttypes-pri.m4, m4/isc-posix.m4):
        (m4/lcmessage.m4, m4/onceonly_2_57.m4, m4/gettext.m4, m4/glibc21.m4):
        (m4/inttypes_h.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4):
        (m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4):
        Don't rename to ..._gl.m4, as this is no longer needed.
        (m4/geteext.m4): Patch to remove the need for intl/*.
        Use autopoint manually, then remove the intl files,
        then undo changes to gnulib files that autoreconf made,
        and then run aclocal/autoconf/autoheader/automake.
        This makes our bootstrap procedure closer to Bison's.
        (po/Makevars): Generate automatically.
        * configure.ac (AC_PREREQ): Update from 2.59 to 2.60.
        (gl_AC_TYPE_INTMAX_T, jm_AC_TYPE_UINTMAX_T): Remove.
        * gnulib.modules: Add inttypes, stdint.
        * lib/.cvsignore: Add close-stream.c, close-stream.h,
        stdint.h, stdint_.h.
        * po/Makefile: Remove; now automatically generated.

        * src/incremen.c (read_incr_db_01): Check input strings more
        carefully.  Do not pass arbitrary char values to isspace, as
        this has undefined behavior.  Likewise for assigning arbitrary
        uintmax_t values to other types.
        (read_negative_num, read_unsigned_num, read_timespec):
        New functions, to check input values a bit more carefuly.
        (read_num): Use read_unsigned_num.  New arg MAX_VAL;
        all callers changed.
        (read_incr_db_2): Use these new functions.
        Use a consistent diagnostic for unexpected EOF.
        (read_directory_file): Do not assign arbitrary uintmax_t value
        to int.
        (read_timespec, write_directory_file_entry, write_directory_file):
        Handle negative time_t values correctly.  We don't bother to do
        this with pre-2 formats, since presumably the time stamps were
        output incorrectly.

        * src/tar.c (doc): Don't use \v in an argument to gettext;
        gettext 0.15 rejects this.

2006-07-24  Sergey Poznyakoff  <gray@gnu.org.ua>

        * src/tar.c (decode_options): Do not require -L with -M -Hpax.
        It could be needed in future, but currently it is not.
        * src/create.c (to_chars_subst): Update comment regarding OLDGNU
        vs. GNU format differences.
        (mode_to_chars): Treat OLDGNU_FORMAT same as GNU_FORMAT. Fixes bug
        reported by TAMUKI Shoichi <tamuki@linet.gr.jp>, which caused
        equivalent `tar cf ...' and `tar rf ...' commands to produce
        different archives.

        * tests/append02.at: New test case
        * tests/Makefile.am, tests/testsuite.at: Add append02.at

2006-07-20  Paul Eggert  <eggert@cs.ucla.edu>

        * bootstrap: Adjust to today's change to gnulib-tool by invoking
        it with --assume-autoconf='latest-stable'.

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

        Adjust to recent gnulib changes.
        * lib/.cvsignore: Remove atexit.c, exit.c, getndelim2.c, getndelim2.h,
        pathmax.h, paxconvert.c, paxerror.h, xstrdup.c.
        Add inttypes.h, mktime.c, wcwidth.h, xstrndup.c, xstrndup.h.
        * src/create.c (start_header): Adjust to API change to mode_adjust.

2006-07-09  Sergey Poznyakoff  <gray@gnu.org.ua>

        * THANKS: Add Ralf Wildenhues

2006-06-25  Sergey Poznyakoff  <gray@gnu.org.ua>

        * scripts/xsparse.c: A sample utility to expand sparse files
        extracted by third-party tars. It is not meant to be installed nor
        to be included in the distribution. It is here, so that it can be
        obtained either from CVS or from the tar web site.

        * src/extract.c (check_time): Use volume_start_time when checking
        for timestamp plausability.
        * src/tar.c: (options, parse_opt): Allow for optional argument to
        the --totals option, which specifies a signal upon delivery of which
        the statistics must be output.
        (main): Call print_total_stats if total_option is set.

2005-11-30  Ian Turner  <ian@zmanda.com>

        * doc/tar.texi (Extracting Specific Files): Remove obsolescent
        FIXME.

2005-11-29  Paul Eggert  <eggert@cs.ucla.edu>

        * NEWS: New option --atime-preserve=system, which uses O_NOATIME.
        * THANKS: Add Ian Turner.

        * configure.ac: Prefer AC_CHECK_HEADERS_ONCE to AC_CHECK_HEADERS.
        Check for stropts.h and sys/filio.h too, for _FIOSATIME.
        * doc/tar.texi: Change "modification time" to "data modification
        time", "change time" to "status change time", and "filesystem" to
        "file system", so that we use terminology consistent with POSIX.
        Use American spacing rather than French for sentence ends.
        "non-dependable" -> "undependable".
        (Option Summary, Attributes): Explain better the pitfalls of the
        --atime-preserve option, and suggest read-only mounts,loopback
        mounts, and noatime mounts for older systems.
        * doc/value.texi (op-atime-preserve-system): Renamed from
        op-atime-preserver-system to fix a misspelling.
        * src/common.h (enum atime_preserve): Use lower case for enum values.
        * src/compare.c: Don't include utimens.h; no longer needed.
        (diff_file): Use set_file_atime rather than utimens; avoid closing
        diff_handle until after this, so that we can set the file time stamp
        via the file descriptor rather than via its name.
        * src/create.c: Don't include utimens.h; no longer needed.
        (dump_regular_finish): Remove.  All callers now do its work inline.
        (dump_dir): New arg FD.  All callers changed.
        Use fdsavedir rather than savedir.
        (unknown_file_error): Arg is a const pointer now.
        (dump_file0): 2nd arg is a const pointer now.
        Treat directories more like files, with respect to --atime-preserve.
        For example, also warn if a directory changes while we are dumping it.
        Prefer file descriptors to file names when retrieving/setting file
        attributes; this saves path-resolution time and allows us to avoid
        changing mtime/ctime on Solaris when restoring atime as root.
        Use O_DIRECTORY when opening directories, to avoid some race conditions.
        Do not reset atime if mtime has changed.  Report an error if
        we cannot reset atime.

        * lib/.cvsignore: Add malloc.h, regcomp.c, regex.c, regex.h,
        regex_internal.c, regex_internal.h, regexc.c; used by rpmatch.

2005-11-29  Ian Turner  <ian@zmanda.com>

        New.
        (op-atime-preserve): Mention METHOD.
        * src/common.h (atime_preserve): New enum.
        (atime_preserve_option): Now of the enum type rather than bool.
        All uses changed.
        * src/compare.c (diff_file): Read with O_NOATIME if asked for.
        * src/create.c (dump_file0): Read regular and CTG files with O_NOATIME
        if asked for.
        * src/tar.c (usage): Mention new usage.

        causing tar to ask for the next volume, it won't hang the
        testsuite.

        * src/buffer.c (flush_write,flush_read): Change data type.
        (flush_archive): Compute actual buffer fill level before calling
        low level function.
        (close_archive): Call flush_archive again if the first call
        resulted in partially filled buffer.
        (try_new_volume): Rewritten handling of initial headers.
        (add_chunk_header): New function. Write an additional header
        before the continuation chunk. The purpose of the header is to

        (simple_flush_write): Take an argument.
        (_gnu_flush_write): Correctly handle partially filled buffers.

        Fix splitting of sparse files between the volumes.

        * src/buffer.c (try_new_volume): Bugfix. Always check

        * src/buffer.c: Rewritten in a more modular fashion to provide
        GNU extensions (multi-volume archives and archive labels) in
        pax format.
        NOTICE, that some of the aspects (e.g. splitting the archive
        on the extended header boundary) are still not solved, others
        (splitting a sparse file between the volume) require additional
        testing. Wait for the next commit.

        * src/compare.c, src/create.c, src/extract.c, src/incremen.c,
        src/list.c: Use mv_.* functions uniformly instead of fiddling
        with the global variables.
        * src/sparse.c: Use mv_.* functions where necessary.
        * src/tar.c (decode_options): Allow to use --multi-volume and
        --label with pax archives.
        * src/xheader.c (xhdr_tab): Support for new GNU keywords.

        * tests/delete01.at, tests/delete02.at, tests/delete03.at,

        * src/xheader.c (xheader_keyword_deleted_p): Remove static
        qualifier.
        (struct xhdr_tab.decoder): Change prototype. POSIX allows string

        Don't filter time stamps through the resolution supported
        by struct stat; keep them to full nanosecond resolution.
        This affects behavior only on older hosts or file systems
        that have lower-resolution time stamps.
        * src/common.h (OLDER_STAT_TIME): Parenthesize arg.
        (OLDER_TAR_STAT_TIME): New macro.
        (code_timespec): New function.
        (BILLION, LOG10_BILLION, TIMESPEC_STRSIZE_BOUND): New constants.
        * src/compare.c (diff_file): Use full time stamp resolution.
        * src/create.c (start_header, dump_file0): Likewise.
        (start_header, dump_file0): Adjust to new structure layout.
        (dump_regular_finish): Simplify by using timespec_cmp.
        * src/extract.c (struct delayed_set_stat): Don't store stat info
        that we don't need, to save space.  All uses changed.
        (struct delayed_set_stat, struct delayed_link, file_newer_p):
        (create_placeholder_file, extract_link, apply_delayed_links):
        Use full time stamp resolution.
        (check_time): Use code_timespec rather than rolling our own code.
        (set_stat, delay_set_stat): Arg now points to tar_stat_info to
        avoid losing time information.  All callers changed.
        * src/list.c (read_and, decode_header, print_heaeder):
        Use full time stamp resolution.
        * src/misc.c (code_timespec): New function.
        * src/tar.h (struct tar_stat_info): Record atime, mtime, ctime
        separately, for benefit of hosts with lower resolution.
        * src/update.c (update_archive): Use full time stamp resolution.
        * src/xheader.c (code_time): Use new code_timespec function
        to simplify code.
        (atime_coder, atime_decoder, ctime_coder, ctime_decoder):
        (mtime_coder, mtime_decoder): Use full time stamp resolution.

        Report time stamps to full resolution in environment.
        Report memory allocation failures rather than ignoring them.
        * src/system.c (time_to_env): New function.
        (oct_to_env, str_to_env, chr_to_env): Report memory allocation failures.
        (stat_to_env): Report full resolution in time stamps.

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

        Merge changes from gnulib for file system sub-second time stamps.
        * configure.ac: Remove checks for struct stat.st_spare1, struct
        stat.st_atim.tv_nsec, struct stat.st_atimespec.tv_nsec, struct
        stat.st_atimensec, as gnulib now does this for us.
        Similarly for LIB_CLOCK_GETTIME.
        * gnulib.modules: Add stat-time.
        * lib/.cvsignore: Add stat-time.h.

2005-06-23  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * src/sparse.c (pax_sparse_member_p): Checking member size
        vs. file size is not reliable enough. Use sparse_map_avail.

        dimped_size to 0.
        (sparse_scan_file): Initialize archive_file_size to 0. The
        variable keeps size of the file *as stored in the archive*, not
        the size reported by stat.

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

        A sweep of the sparse code prompted by a bug report by Jim Meyering.
        * src/sparse.c: Include <inttostr.h>.
        (struct tar_sparse_file): offset and dumped_size are off_t, not
        size_t.  optab is now const *.
        (dump_zeros): Return bool success flag, not off_t.
        All callers changed.

        (parse_scan_file): Cache commonly-used parts of file.
        Use an auto buffer, not a static one.
        Don't bother clearing the buffer; not needed.
        Don't bother clearing items that are already clear.
        (oldgnu_optab, star_optab, pax_optab): Now const.
        (sparse_dump_region): Don't bother clearing the buffer before
        reading into it; just clear the parts that aren't read into.
        (sparse_dump_file): Clear the whole local variable 'file'.
        (diff_buffer): Remove; now a local var.
        (check_sparse_region): Don't bother clearing buffer before
        reading into it.  Don't assume off_t is promoted to long.
        (oldgnu_get_sparse_info, star_get_sparse_info):

        * src/tar.h (struct tar_stat_info): had_trailing_slash is
        now bool, not int.
        * src/xheader.c (sparse_offset_coder, sparse_numbytes_coder):
        Rewrite to avoid cast.
        (sparse_offset_decoder, sparse_numbytes_decoder):

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

        * src/common.h (timespec_lt): Add a return type: bool.

2005-06-21  Paul Eggert  <eggert@cs.ucla.edu>

        Further improvements inspired by Jim Meyering's fixes.

        Simplify test for old GNU format.
        (start_header): Put in placeholders for uid, etc., even when

        fit in 63 bytes (!) when printed.
        (decode_record): Don't bother to check for ERANGE; an out of range
        value must be treater than len_max anyway.

        All callers changed.
        Handle negative time stamps.  Truncate towards minus infinity
        consistently.  Improve overflow checks, and output a better
        diagnostic on overflow.
        (code_num): Don't assume uintmax_t can be printed in 99 bytes (!).
        (decode_num): New function, for better diagnostics.
        (atime_coder, atime_decoder, gid_decoder, ctime_coder):
        (ctime_decoder, mtime_coder, mtime_decoder, size_decoder):

2005-06-21  Jim Meyering  <jim@meyering.net>

        Carefully crafted invalid headers can cause buffer overrun.
        Invalid header fields go undiagnosed.
        Some valid time strings are ignored.

        * src/xheader.c (sparse_numblocks_decoder): Remove unchecked use
        of `calloc'.  Use xcalloc instead.
        (decode_time, gid_decoder, size_decoder, uid_decoder):
        (sparse_size_decoder, sparse_offset_decoder, sparse_numblocks_decoder):
        Ensure that the result of calling xstrtoumax is no larger than
        the maximum value for the target type.  Upon any failure, exit with
        a diagnostic.
        (sparse_numblocks_decoder): Avoid buffer overrun/heap corruption:
        use x2nrealloc, rather than `n *= 2' and xrealloc(p, n,....
        (decode_time): Rewrite to accept time strings like
        1119018481.000000000.  Before, such strings were always ignored.

2005-05-12  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * NEWS: Updated
        * THANKS: Updated

        that shrunk during archiving. Repored by Frank Heckenbach.
        * src/extract.c (file_newer_p): Return false if file does not
        exist
        (prepare_to_extract): Correct warning wording.
        * tests/truncate.at: New test case
        * tests/Makefile.am: Add truncate.at
        * tests/testsuite.at: Likewise.

        * doc/.cvsignore: Updated
        * lib/.cvsignore: Updated
        * tests/.cvsignore: Updated

2005-05-02  Paul Eggert  <eggert@cs.ucla.edu>

        * tests/multivol04.at: Tell awk to read from /dev/null.

        Adjust to recent gnulib changes.
        * lib/.cvsignore: Add dup-safer.c, fd-safer.c, unistd-safer.h.
        * src/common.h (initial_umask): New var.
        * src/create.c (start_ueader): Use it, and adjust to new modechange
        API.
        (hash_link): unsigned -> size_t parameters and result.
        * src/incremen.c (hash_directory): Likewise.
        * src/names.c (hash_string_hasher): Likewise.
        * src/tar.c (parse_opt): Set it, and adjust to new modechange API.

2005-04-19  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * tests/Makefile.am: Add shortrec.at.

2005-04-18  Paul Eggert  <eggert@cs.ucla.edu>

        * src/buffer.c (reading_from_pipe): Remove.  All uses removed.
        (short_read): Don't warn about short reads; they're normal.
        * tests/shortrec.at: New file.
        * tests/testsuite.at: Include it.

        * bootstrap (gnulib_modules): Don't create a file modlist.tmp, as
        it is sometimes left behind as a garbage file (maybe due to the
        multiple traps?).

2005-04-14  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * src/list.c: Handle Solaris 'X' type flag
        * src/tar.h (SOLARIS_XHDTYPE): New define

2005-04-06  Sergey Poznyakoff  <gray@mirddin.farlep.net>

        * src/tar.c: Minor fixes to text messages. Proposed by Benno
        Schulenberg.
        * src/extract.c: Likewise
        (extract_file): Assign orig_file_name
        to save_name uniformly over the program. This fixes matching
        directory names at the start of an archive volume.
        * src/buffer.c (flush_write): Warn when the name of the archive
        straddling volume boundary is longer than 100 characters. Earlier
        behavior was to issue a fatal error.
        (struct zip_magic): Reverted part of changes from 2005-04-04.
        They make the maintenance too costly. Removing `unsigned'
        qualifier from `magic' member should be enough.
        * src/compare.c (diff_init): Read directory file if in listed
        incremental. This prevents spurious 'Contents differ' diagnostics.
        (diff_archive): Minor fixes to text messages
        (diff_file,diff_dumpdir,diff_multivol): Assign orig_file_name
        to save_name uniformly over the program. This fixes matching
        directory names at the start of an archive volume.
        * src/create.c: Assign orig_file_name
        to save_name uniformly over the program. This fixes matching
        directory names at the start of an archive volume.
        * src/list.c: Likewise

        * tests/multiv03.at: Modified to match the new behavior
        * tests/multiv04.at: New file. Test splittind directory members between
        the archive volumes.
        * tests/Makefile.am: Add multiv04.at
        * tests/testsuite.at: Likewise.

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

        * configure.ac (AC_CONFIG_AUX_DIR): Rename from config to build-aux,
        for reasons discussed in the thread beginning at
        <http://lists.gnu.org/archive/html/bug-gnulib/2005-03/msg00119.html>.
        * .cvsignore: Remove config; add build-aux.

        * src/buffer.c (struct zip_magic): Use char arrays, not pointers.
        The unsigned char * pointer ran afoul of pedantic C compilers, and
        we didn't need pointers anyway.  Put the size field before the
        data to avoid unnecessary padding.  All uses changed.
        (magic) Make it const, since it doesn't change.  All uses changed.

2005-04-02  Paul Eggert  <eggert@cs.ucla.edu>

        * src/xheader.c (decode_record): Don't dump core when given
        a corrupted extended header.  Problem reported by Jim Meyering.
        Also, check for other ways that the header might be invalid,
        e.g., missing newline at end.  Do not allow keys with nulls.
        Allow blanks before and after length, as POSIX requires.
        Do not allow leading "-" in length.  Check for length overflow.
        (xheader_decode, xheader_decode_global): Let decode_record
        check for exhaustion of record.
        (xheader_read): Null-terminate the extended record;
        decode_record relies on this.

2005-03-21  Paul Eggert  <eggert@cs.ucla.edu>

        * bootstrap (TP_URL): Change from
        <http://www2.iro.umontreal.ca/~gnutra/po/maint/tar/> to
        <http://www.iro.umontreal.ca/translation/maint/tar/> to avoid
        some redirection glitches.
        Use "trap - 0" rather than "trap 0" to fix a POSIX-conformance bug.
        * doc/.cvsignore: Change "tar.info" to "tar.info*".  Sort.
        * lib/.cvsignore: Add intprops.h (new gnulib file).

2005-03-04  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * src/list.c (print_header): Print UID/GID in case of
        empty user/group name. This could occur when dumping
        files belonging to non-existing users and when listing
        broken archives.
        Reported by Igor Lautar.

        * src/create.c: Correctly parse empty uname/gname
        * src/sparse.c (sparse_scan_file): Bugfix. offset had
        incorrect type.

        * scripts/backup.in: Use `head -n 1'. Provide missing
        argument to ${MT_STATUS}. Proposed by Jan Merka.
        * scripts/backup.sh.in: Likewise. Fixed typo in
        MT_OFFLINE assignment.
        * scripts/restore.in (restore_fs): Use root_fs

2005-02-15  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * src/create.c: Replace strdup with xstrdup
        * src/names.c: Likewise
        * src/tar.c: Likewise

        * tests/append01.at: Added reference to bug-tar archive
        * tests/listed02.at: Use -print with find.

2005-02-11  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * THANKS: Added Tim Adye. Fixed UTF.
        * src/list.c (read_header): Removed assignment to
        oldgnu_header.isextended. It was breaking append mode.

        * tests/append01.at: New test.
        * tests/Makefile.am: Added append01.at
        * tests/testsuite.at: Likewise

2005-02-06  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * gnulib.modules: New file. List of required gnulib
        modules.
        * bootstrap: Merge list of required modules from
        paxutils with that from tar proper.
        * src/tar.c: Various fixes in help and diagnostic messages.

2005-02-05  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * src/common.h (EXTRACT_OVER_PIPE): New macro
        * src/compare.c: Code clean up.
        * src/extract.c (extract_archive): Do not check for
        EXTRACT_OVER_PIPE, decode_options() does this.
        * src/misc.c (exec_error,fork_error,dup2_error)
        (pipe_error): Removed unneeded functions.
        * src/system.c (sys_exec_command): Use xclose, xpipe,
        xfork, xdup2 and exec_fatal.
        * src/tar.c (options): Improved sorting. Document --backup=off.
        (decode_options): Clear backup_option if necessary.

2005-02-05  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        Initial implementation of --to-command option proposed
        by Hansjoerg Lipp.

        * bootstrap: Get setenv module from gnulib
        * src/buffer.c: Do not use 8-bit chars in comments
        * src/common.h (to_command_option)
        (ignore_command_error_option): New globals
        (sys_exec_command,sys_wait_command): New commands
        * src/extract.c (extract_file): Handle to_command_option
        Fix error recovery: decrease `size' by `written', not
        by `count', otherwise tar misses the next header
        Do not diagnose write error if to_command_option
        is set, since the command may have exited prematurely.
        It would be better to check for sigpipe, though.
        (prepare_to_extract): Handle to_command_option
        * src/misc.c (exec_error, fork_error, dup_error)
        (pipe_error): New functions
        * src/system.c (sys_exec_command)
        (sys_wait_command): New functions
        * src/tar.c: Handle new options --to-command,
        --ignore-command-error
        * THANKS: Added Hansjoerg Lipp

2005-02-03  Paul Eggert  <eggert@cs.ucla.edu>

        * src/list.c (from_header): New arg OCTAL_ONLY, normally false.
        All uses changed.  Fix typo that sometimes suppressed all "Archive
        contains obsolescent base-64 headers" warnings, not just the first
        one.
        (tar_checksum): Accept only octal checksums, since they aren't
        supposed to overflow into weird formats.

        Adjust to gnulib changes.
        * lib/.cvsignore: Add chdir-long.c, chdir-long.h, memrchr.c,
        memrchr.h, openat.c, openat.h.  Remove pathmax.h (added by
        mistake, perhaps?), sysexit.h (my typo), xstrdup.c (gnulib removed
        this file).  Sort entries.

2005-02-04  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

2005-02-01  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * bootstrap: Add a comment to lib/Makefile.am saying that this
        is an autogenerated file.
        Exit with code 1 if any of autotools fails.
        * lib/Makefile.tmpl: Insert Emacs magic to the first line.
        * tests/Makefile.am: Add append.at

        * m4/.cvsignore: Ignore all *.m4 files

2005-01-18  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        Rewritten handling of -T (--files-from) option. Now it
        inserts the file names immediately into argv array which allows
        for:
        1) any valid tar options (including another -T) to be used in the file
        2) any number of -T options to be given in command line

        * src/list.c (read_header): Fixed calculation of the

2005-01-04  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/Makefile.tmpl (localedir.h): Omit needless quotes and a
        needless sed command.  Problem reported by Paul Jarc.

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

        Accommodate latest gnulib.
        * doc/.cvsignore: Add getdate.texi.
        * bootstrap: Do not treat alloca-opt specially; this is no
        longer needed (and breaks builds) with latest gnulib.

        formats.
        * src/tar.c (decode_options): Ignore --seek if used with --delete.

2004-02-21  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * src/create.c (dump_file0): The conditional at line
        1296 prevented incremental backups on individual files
        from working, as reported by Andreas Schuldei
        <andreas@schuldei.org>.

        This is due to the condition

          (0 < top_level || !incremental_option)

        Removing it makes incremental backups work for individual
        files as well as for directories. On the other hand, it does
        not affect other functionality, as shown by the reasoning below:

        To begin with, the two parts of this condition are mutually
        superfluous, because

          1) when top_level < 0, incremental_option == 1
          so the condition yields false
          2) when top_level >= 0, incremental_option == 0
          so the condition yields true.

        In other words, it is completely equivalent to

              (!incremental_option)

        Now, let's consider the effect of its removal. There are two cases:

        1) when incremental_option==1
        This means incremental backup in progress. In this case dump_file
        is invoked only for directories or for files marked with 'Y' by
        get_directory_contents. The latter are those that did not meet the
        condition in incremen.c:242, which is exactly the same condition
        as this at create.c:1296. So, for these files the check
        (!incremental_option) is useless, since the rest of the
        conditional will yield false anyway. On the other hand, if
        dump_file is invoked on a directory, the conditional will yield
        false due to !S_ISDIR assertion, so these will be processed as usual.

        Thus, for this case the extra condition (!incremental_option) is
        irrelevant, and its removal won't alter the behavior of tar,
        *except* that it will enable incremental backups on individual
        files, which is the wanted effect.

        2) when incremental_option==0
        In this case the condition yields true and its removal does not
        affect the functionality.

        * THANKS: Updated
        * configure.ac: Raised patchlevel to 93
        * src/incremen.c: Minor stylistic fixes.
        * tests/listed01.sh: New test. Check listed incremental
        backups on individual files.

        (simple_finish_header): New function.
        (finish_header): Use simple_finish_header() to break recursive
        dependency between this function and write_extended().
        * src/tar.c (assert_format): Do not bail out if several
        --format arguments are given. This is a common case when
        TAR_OPTIONS are used.

        compiled-in defaults.
        Use POSIX format if no --format option was given and
        --pax-option was specified.
        Do not allow to use --pax-option unless the archive format is
        set to POSIX (or reading subcommand is requested).

        * src/update.c (update_archive): Write global extended header if
        constructed.
        * src/xheader.c (xheader_format_name): Bugfix.

        (xheader_write,xheader_write_global): New function.
        (xheader_decode): Modified to honor overrides whatever

        Fix Debian bug 230872, originally reported by Jeff King in
        <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=230872>.

        * doc/tar.texi (posix compliance): Remove.  The whole section
        was a misunderstanding of what POSIXLY_CORRECT is supposed to
        mean.  The GNU Coding Standards says that POSIXLY_CORRECT
        is for disabling extensions that are incompatible with POSIX:
        it is not for disabling compatible extensions.  All references
        to this section removed.
        (posix): This format is created only if the posix format is
        specified; it is no longer created if gnu format is specified
        and POSIXLY_CORRECT is set.
        * src/tar.c (decode_options): Ignore POSIXLY_CORRECT.
        POSIX does not specify the behavior of tar, so we should
        not worry about POSIXLY_CORRECT here.

        Synchronize with Gettext 0.13.1, Automake 1.8, Autoconf 2.59,
        and translation website.

        * bootstrap: Don't bother skipping codeset.m4, glibc21.m4,
        intdiv0.m4, inttypes_h.m4, inttypes.m4, inttypes-pri.m4,
        isc-posix.m4, and lcmessage.m4 from gnulib.  This list of files is
        a bit obsolete anyway, now that gettext 0.13.1 is out.  Also, the
        files are replaced by autoreconf.  Also, there seems to be a bug
        in gettext/autoconf/automake if we try to omit these files after
        autoreconf has replaced them, even though the gettext manual says
        they're optional.  So give up and just include them for now, even
        though they make 'configure' longer and slower.

        Change translation URL from
        <http://www.iro.umontreal.ca/contrib/po/maint/tar/> to
        <http://www2.iro.umontreal.ca/~gnutra/po/maint/tar/> to
        accommodate translator website revamp.

        Fail if autoreconf fails.

        * m4/.cvsignore: Add intmax.m4, longdouble.m4, printf-posix.m4,
        signed.m4, size_max.m4, wchar_t.m4, wint_t.m4, xsize.m4, to
        ignore files now supplied by gettext 0.13.1.

        (fill_in_sparse_array): Moved here from compare.c.
        (extract_sparse_file): Now returns off_t, giving size left.
        Truncate file at end.
        (extract_archive): Use safer_name_suffix rather than rolling our own.
        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

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.

        (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,

        (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.

        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).

        Include langinfo.h if needed.
        Use locale_charset only if USE_INCLUDED_LIBINTL;

        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'

        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 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>

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

        * 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.

        (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.

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

        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.

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

        * m4/fnmatch.m4 (jm_FUNC_FNMATCH): Upgrade to serial 4, but

        * 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.

        '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.

        (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.

        if --no-recursion is specified.
        * src/tar.c (NO_RECURSE_OPTION): Remove.
        (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.

        * src/buffer.c (check_label_pattern):
        Make sure header name is a string before
        passing it to fnmatch.
        (init_volume_number): Check for global_volno overflow.
        (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.
        (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: 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 inaccurate comment for xrealloc.

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

        * lib/quotearg.c (ISASCII): Add #undef and move definition to follow
        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>

        * lib/human.c (adjust_value): New function.
        (human_readable_inexact): Apply rounding style even when printing
        approximate values.

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

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

        * lib/human.c (human_readable_inexact): Allow an input block size
        that is not a multiple of the output block size, and vice versa.

        * lib/getdate.y (get_date): Apply relative times after time zone
        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.
        (iswprint): Define to 1 if we lack it

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.

2000-02-28  Paul Eggert  <eggert@twinsun.com>

        * lib/quotearg.c (ALERT_CHAR): New macro.

        OLD_CTIME.

2000-02-18  Paul Eggert  <eggert@twinsun.com>

        * lib/getdate.y: Handle two-digit years with leading zeros correctly.
        (textint): New typedef.
        (parser_control): Changed from struct parser_control to typedef
        (for consistency).  Member year changed from int to textint.  All
        uses changed.
        (YYSTYPE): Removed; replaced by %union with int and textint
        members.
        (tID): Removed; not used.
        (tDAY, tDAY_UNIT, tDAYZONE, tHOUR_UNIT, tID, tLOCAL_ZONE,
        tMERIDIAN, tMINUTE_UNIT, tMONTH, tMONTH_UNIT tSEC_UNIT, tSNUMBER,
        tUNUMBER, tYEAR_UNIT, tZONE, o_merid): Now of type <intval>.
        (tSNUMBER, tUNUMBER): Now of type <textintval>.
        (date, number, to_year): Use width of number in digits, not its
        value, to determine whether it's a 2-digit year, or a 2-digit
        time.
        (yylex): Store number of digits of numeric tokens.  Return '?' for
        unknown identifiers, rather than (unused) tID.

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

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

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

        * m4/c-bs-a.m4:
        Change quoting to be compatible with future autoconf versions.

        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.

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

        * 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.

        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

        Check for readdir and closedir errors.
        (maybe_backup_file): Report "stat" for stat errors.

        (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

        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

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>

        * 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.

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

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

        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.

        (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.
        Likewise for find_next_block.

        * src/buffer.c, src/common.h (<human.h>): Include.

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

        * doc/Makefile.am:
        ($(srcdir)/tar.info): Add -I$(srcdir) so that subdir builds work.

        Modernize sample backup script.

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

        * lib/xstrtol.c: Remove.

        * src/tar.c (decode_options):
        Set newer_time_option to TYPE_MINIMUM, so that
        negative timestamps are handled correctly.
        Replace invocations of xstrtol and xstrtoul with xstrtoumax, for
        uniformity (and so that we don't need to have the other fns).
        (main): Remove call to init_total_written; no longer needed.

        * m4/ulonglong.m4 (jm_AC_TYPE_UNSIGNED_LONG_LONG):
        Make sure that we can shift, multiply

        * m4/xstrtoumax.m4 (jm_AC_PREREQ_XSTRTOUMAX): Check whether
        <inttypes.h> defines strtoumax as a macro (and not as a function).
        HP-UX 10.20 does this.

        * 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.

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.

        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.

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.

        * 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

        Convert daddr_t and off_t values ourselves, since they might be longer
        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.

        * src/update.c:
        (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,

        since it might be longer than long.

        * src/mangle.c (extract_mangle):
        Check for overflow when converting off_t to size_t.
        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.

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

        * src/misc.c (quote_copy_string):
        Use size_t when appropriate.  Remove now-useless casts.

        real_s_totsize, real_s_sizeleft, current_block_ordinal):
        Now off_t.
        (write_error): Arg is now ssize_t.
        (child_pid): Now pid_t.
        (available_space_after): Now size_t.

        (child_open_for_compress, child_open_for_uncompress, flush_write,
        open_archive, flush_write, write_error, flush_read, close_archive):
        Use pid_t, ssize_t, size_t when appropriate.  Remove now-useless
        casts.  Use unsigned long to print *_t types, except use
        STRINGIFY_BIGINT for off_t.

        * src/delete.c (records_read): Now daddr_t.
        (move_archive): Arg is now daddr_t.  Check for overflow when
        computing offset.
        (move_archive, delete_archive_members): Use daddr_t, off_t when
        appropriate.  Remove now-useless casts.

        * src/rmt.h (rmt_read__, rmt_write__): Now returns ssize_t.
        (rmt_lseek): Now returns off_t.

        * src/create.c (to_oct):
        Now static.  Value arg is now uintmax_t.  Accept new args
        giving name of type of octal field, for error messages.  Report an
        error if the value is too large to fit in the field.
        (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): New functions.

        (write_eot, write_long, finish_header, deal_with_sparse,
        finish_sparse_file, dump_file): Use dev_t, off_t, ssize_t, size_t when
        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.
