Version 1.35
2023-07-17 Sergey Poznyakoff <gray@gnu.org>
Use full-read instead of safe-read
This helps handle archiving on certain filesystems where read()
returns less bytes than requested when reading from a regular
file.
References:
https://savannah.gnu.org/bugs/index.php?64426
https://lists.gnu.org/archive/html/bug-tar/2021-07/msg00001.html
* gnulib.modules: Add full-read.
* src/common.h: Include full-read.h
* src/misc.c: Use full_read.
* src/sparse.c: Likewise.
* src/update.c: Likewise.

Fix typo in comments
This and the bug fixed by the previous commit were reported by
Benno Schulenberg.
2023-07-10 Sergey Poznyakoff <gray@gnu.org>
Fix --update --wildcards
* src/common.h (name): New field: is_wildcard.
(name_scan): Change protoype.
* src/delete.c: Update calls to name_scan.
* src/names.c (addname, add_starting_file): Initialize
is_wildcard.
(namelist_match): Take two arguments. If second one is true,
return
only exact matches.
(name_scan): Likewise. All callers updated.
(name_from_list): Skip patterns.
* src/update.c (remove_exact_name): New function.
(update_archive): Do not remove matching name, if it is a pattern.
Instead, add a new entry with the matching file name.
* tests/update04.at: New test.
* tests/Makefile.am: Add new test.
* tests/testsuite.at: Include new test.
* NEWS: Update.
2023-07-10 Benno Schulenberg <bensberg@telfort.nl>
Various fixes in the documentation
* doc/tar.1: Add missing dots, use plural when necessary,
tweak a wording. Remove an incorrect observation, three times.
Add some missing articles, correct some formatting,
and expand the opaque descriptions of two options.
* doc/tar.texi: Drop a stray `cd` command from an example.
Correct two cross references, correct the paragraph
about the manpage, and unbreak a URL.
* src/names.c: Correct and shorten an error message:
"non-optional"
means "mandatory", but "non-option" is what was meant. And the
phrase "in archive create or update mode" was both unneeded and
incomplete.
* tests/positional01.at: Change expected error text.
* tests/positional02.at: Likewise.
* tests/positional03.at: Likewise.

build: update gnulib submodule to latest
2023-06-26 Paul Eggert <eggert@cs.ucla.edu>
tar: extract delayed links in order
Extract delayed links in tar file order, rather than
in hash table order with modifications.
This is simpler and more likely to use the kernel’s
cached filesystem data, assuming related delayed links
are nearby in the tar file.
* src/extract.c (struct delayed_link.has_predecessor):
Remove. All uses removed.
(delayed_link_head, delayed_link_tail): New static vars.
This resurrects delayed_link_head’s old function
except that the linked list is now in forward order, not reverse.
(find_delayed_link_source): Now simply returns bool,
since the callers no longer need the pointer.
(create_placeholder_file):
Put the delayed link at the end of the linked list.
Omit no-longer-needed last arg. All callers changed.
(apply_delayed_links): Simplify now that we can just iterate
through the delayed_link_head list.
2023-06-26 Paul Eggert <eggert@cs.ucla.edu>
tar: make safe for -Wunused-parameter
This also ports to C23 [[maybe_unused]].
* configure.ac (WARN_CFLAGS): Do not add -Wno-unused-parameter.
Add MAYBE_UNUSED where needed in source code.
Also, put it at the front where C23 requires it.
2023-06-26 Paul Eggert <eggert@cs.ucla.edu>
* po/.gitignore: Omit redundant *~ entries.
2023-06-26 Paul Eggert <eggert@cs.ucla.edu>
tar: omit unnecessary freeing
* src/tar.c (main): Omit unnecessary freeing.
2023-06-18 Sergey Poznyakoff <gray@gnu.org>
Make sure each delayed link entry is visited once
* src/extract.c (create_placeholder_file): Use FLEXNSIZEOF
(overlooked
by c542d3d0c8)
(apply_delayed_links): Don't follow the "next" chain after
its entries
have been applied.
2023-06-17 Paul Eggert <eggert@cs.ucla.edu>
Omit unnecessary freeing
* src/extract.c (apply_delayed_link): Don’t bother to
free memory, as we’re about to exit.
2023-06-17 Paul Eggert <eggert@cs.ucla.edu>
Port to strict C99 struct hack
Portability bug caught by GCC 13 -fstrict-flex-arrays.
* gnulib.modules: Add flexmember.
* src/create.c (struct link):
* src/exclist.c (struct excfile):
* src/extract.c (struct delayed_link, struct string_list):
Include <flexmember.h>. Use FLEXIBLE_ARRAY_MEMBER, for
portability to strict C99 or later. All storage
allocations changed to use FLEXNSIZEOF.
2023-06-17 Paul Eggert <eggert@cs.ucla.edu>
Use Gnulib ‘dup2’ module
This simplifies code that would otherwise use dup and close.
* gnulib.modules: Add dup2.
* src/system.c: Add #pragma to pacify GCC 13.
(xdup2): Simplify by using dup2.
2023-06-17 Paul Eggert <eggert@cs.ucla.edu>
Use Gnulib ‘free-posix’ module
Paxutils uses it so we should too.
* gnulib.modules: Add ‘free-posix’.
* src/misc.c (remove_any_file): Assume ‘free’ keeps errno.
2023-06-17 Paul Eggert <eggert@cs.ucla.edu>
* buffer.c: work around GCC bug 109856
Recommend Y2038 safety
build: update gnulib and paxutils submodules to latest
* .gitignore: Add slash, as bootstrap does this now.
Sync bootstrap from Gnulib
2023-06-06 Pavel Raiskup <praiskup@redhat.com>
Comment a bit on the xattr extraction logic
* src/extract.c (extract_file): Document why we pre-create
with S_IWUSR.
(set_xattr): Drop the INVERT_PERMISSIONS doc leftover.
2023-06-06 Pavel Raiskup <praiskup@redhat.com>
Fix --xattr-include='*' documentation
* doc/tar.texi (Extended File Attributes): The default extraction
pattern consists of just 'user.*' namespace only. While on
it, try
to explain the reasons for this default behavior.
2023-05-18 Sergey Poznyakoff <gray@gnu.org>
Honor --numeric-owner when storing ACL entries
Based on patch from Fabian Grünbichler
<f.gruenbichler@proxmox.com>
* src/xattrs.c (acls_get_text): New function. If given
--numeric-owner,
use acl_to_any_text to convert ACL to textual representation.
Print
warning if that function is not available.
(xattrs__acls_get_a, xattrs__acls_get_d): Use acls_get_text.
2023-05-18 Sergey Poznyakoff <gray@gnu.org>
Upgrade paxutils to d50ea31268
This fixes two bugs related to remote archives:
1. Access from unprivileged user accounts.
2. Malfunctioning seek (L) command.
2023-05-18 Sergey Poznyakoff <gray@gnu.org>
Don't copy DISTFILES during bootstrapping
DISTFILES are necessary only during bootstrapping and should
not be
distributed.
This partially reverts commit 9f0e54ab2.
2023-05-01 Benno Schulenberg <bensberg@telfort.nl>
Add missing option to manpage and remove duplicate operation
* doc/tar.1: Add needed option -f after operation -A, sort
operation -t
alphabetically, add --file after --concatenate, consistently
use long
option --file in the GNU-style section, and delete duplicate
--update.
* doc/tar.texi: Add small missing word, and lowercase a letter.
2023-04-18 Sergey Poznyakoff <gray@gnu.org>
Change some wording in doc/intern.texi
2023-04-18 Anton Makrushin <makrusan@gmail.com>
Exclude VCS directory with writing from an archive
See https://savannah.gnu.org/bugs/?62859
2023-02-21 Sergey Poznyakoff <gray@gnu.org>
Detect EOF when deleting from archive.
See https://savannah.gnu.org/bugs/?63823
* src/delete.c (flush_file): Break the loop on EOF.
* tests/delete06.at: New test.
* tests/Makefile.am: Add new test.
* tests/testsuite.at: Likewise.
2023-02-11 Sergey Poznyakoff <gray@gnu.org>
Changes in extended header decoder
* src/xheader.c (decode_time): Fix error detection.
(raw_path_decoder): Ignore empty paths.
2023-02-11 Sergey Poznyakoff <gray@gnu.org>
Prevent dead loop in extract_file
* src/extract.c (maybe_recoverable): If make_directories indicates
success, suppose some intermediate directories have been made,
even
if in fact they have not. That's necessary to avoid dead
loops when
maybe_recoverable is called with the same arguments again.
2023-02-11 Sergey Poznyakoff <gray@gnu.org>
Fix boundary checking in base-256 decoder
* src/list.c (from_header): Base-256 encoding is at least 2 bytes
long.
2023-01-06 Paul Eggert <eggert@cs.ucla.edu>
Adjust to Gnulib macro renaming
* src/Makefile.am, tests/Makefile.am (LDADD):
Gnulib renamed LIB_HAS_ACL to FILE_HAS_ACL_LIB.
2023-01-06 Paul Eggert <eggert@cs.ucla.edu>
build: update gnulib, paxutils submodules to latest
2023-01-06 Paul Eggert <eggert@cs.ucla.edu>
Go back to single-file bootstrap
Gnulib now supports a single-file bootstrap with --pull
and --gen options, in place of the three files
autopull.sh, autogen.sh, bootstrap-funclib.sh.
This keeps the top level a bit cleaner.
* bootstrap: Sync from Gnulib build-aux/bootstrap
instead of from top/bootstrap.
* autopull.sh, autogen.sh, bootstrap-funclib.sh: Remove.
2023-01-06 Paul Eggert <eggert@cs.ucla.edu>
Fix ‘assume’ include
* src/tar.c: Include verify.h, needed for ‘assume’.
2023-01-06 Paul Eggert <eggert@cs.ucla.edu>

2022-12-29 Sergey Poznyakoff <gray@gnu.org>
Optionally warn about missing zero blocks at the end of the
archive
(In response to savannah bug #63574)
* doc/intern.texi: Document actual tar behaviour in regard to
missing end-of-file marker.
* doc/tar.texi: Rewrite the "warnings" section. Document
--warning=missing-zero-blocks
* src/common.h (WARN_MISSING_ZERO_BLOCKS): New constant.
(WARN_ALL): Include all warning bits.
* src/list.c (read_and): If EOF is reached without seeing
end-of-file
blocks and the "missing-zero-blocks" warning is requested,
warn about
the fact.
* src/warning.c: New warnings: "missing-zero-blocks", "verbose".
(warning_option): Change definition to reflect changes in common.h
2022-12-27 Sergey Poznyakoff <gray@gnu.org>
Fix example use of find command in documentation
2022-12-26 Sergey Poznyakoff <gray@gnu.org>
Fix savannah bug #63567
* src/buffer.c (short_read): Increase records_read only if a full
record has been read.
2022-11-04 Paul Eggert <eggert@cs.ucla.edu>
Fix -Af F bug when F is not a regular file
Problem reported by Boris Gjenero in:
https://lists.gnu.org/r/bug-tar/2022-11/msg00001.html
* src/update.c (append_file): Don’t assume that FILE_NAME is a
regular file whose size can be determined before reading.
Instead, simply read from the file until its end is reached.
2022-11-04 Paul Eggert <eggert@cs.ucla.edu>
Fix README-* files
README-alpha is for alpha releases, which are not from Git or
CVS, so
omit mention of that. I'm not sure we'll ever do alpha releases,
but
if we do, README-alpha assumes the tarballs are already bit.
Update README-hacking with info that was mistakenly put into
README-alpha. Also mention Bison, needed for parse-date.y.
2022-10-27 Paul Eggert <eggert@cs.ucla.edu>
Fix undefined behavior on bad extended header
* src/xheader.c (locate_handler): Avoid undefined behavior
if strlen(keyword) < kwlen.
2022-10-22 Sergey Poznyakoff <gray@gnu.org>
Fix savannah bug #63123
The bug was introduced by commit 79d1ac38c1, which didn't
take into
account all the consequences of returning RECOVER_OK on EEXIST, in
particular interactions with the delayed_set_stat logic.
The commit 79d1ac38c1 is reverted (the bug it was intended to fix
was actually fixed by 79a442d7b0). Instead:
* src/extract.c (maybe_recoverable): Don't call maybe_recoverable
if EEXIST is reported when UNLINK_FIRST_OLD_FILES option is set.
2022-10-22 Sergey Poznyakoff <gray@gnu.org>
Fix savannah bug #63250
* src/buffer.c (magic): Add signature of LZMA files produced
by xz.
2022-10-08 Paul Eggert <eggert@cs.ucla.edu>
Mention previous bug fix
2022-10-08 Paul Eggert <eggert@cs.ucla.edu>
tests: check for recently-fixed bug
* tests/exclude17.at: New file.
* tests/testsuite.at (AT_CHECK_TIMESTAMP): Add it.
2022-10-08 Aurélien Martin <amartin@witekio.com> (tiny change)
tar: fix --exclude-vcs-ignores memory
The function frees the patterns' wordsplit structure without
asking
add_exclude to reallocate the strings. In many cases, this
leads to
each file name in the directory being checked against the memory
location where it just got reallocated.
* src/exclist.c: Use EXCLUDE_ALLOC.
2022-09-11 Paul Eggert <eggert@cs.ucla.edu>
build: update submodules to latest
* src/common.h: Include <inttostr.h> since paxutils no longer
does.
(STRINGIFY_BIGINT): New macro, copied from older paxutils.
(UINTMAX_STRSIZE_BOUND): New constant, also from older paxutils.
2022-09-11 Paul Eggert <eggert@cs.ucla.edu>
Fix bootstrap.conf when no paxutils
* bootstrap.conf: Don’t assume the paxutils subdirectory already
exists, when bootstrapping.
2022-09-04 Paul Eggert <eggert@cs.ucla.edu>
Fix data loss when acting as filter
This bug was introduced by the recent lseek-related changes.
* src/delete.c (delete_archive_members):
* src/update.c (update_archive):
Copy the member if acting as a filter, rather than lseeking over
it, which is possible if stdin is a regular file.
* src/list.c (skim_file, skim_member):
* src/sparse.c (sparse_skim_file):
New functions, for copying when a filter.
* src/list.c (skip_file): Remove; replaced with skim_file.
All callers changed.
(skip_member): Reimplement in terms of skim_member.
* src/sparse.c (sparse_skip_file):
Remove; replaced with sparse_skim_file. All callers changed.
* src/update.c (acting_as_filter): New static var.
(update_archive): Set it; this is like delete.c.
* tests/delete01.at (deleting a member after a big one):
* tests/delete02.at (deleting a member from stdin archive):
Also test filter case.
2022-09-03 Paul Eggert <eggert@cs.ucla.edu>
Fix --delete bug with short reads
* gnulib.modules: Add idx.
* src/common.h: Include idx.h.
* src/delete.c (move_archive): Don’t botch short reads.
2022-08-27 Paul Eggert <eggert@cs.ucla.edu>
Do not diagnose same xattr file twice
* src/extract.c (set_xattr): Simplify, by having it do only
the mknodat and xattrs_xattrs_set, rather than also
trying to recover from failure. Caller simplified too.
* tests/xattr07.at (xattrs: xattrs and --skip-old-files):
Adjust test to match fixed behavior.
2022-08-27 Paul Eggert <eggert@cs.ucla.edu>
Fix bug with -x --xattr read-only files
Problem reported by Kevin Raymond in:
https://bugzilla.redhat.com/show_bug.cgi?id=1886540
* src/extract.c (open_output_file): If we already created the
empty file, do not open with O_EXCL, or with O_CREAT or O_TRUNC
for that matter. Instead, use only O_NOFOLLOW to avoid some
races. When estimating current mode, use openflag & O_EXCL rather
than overwriting_old_files.
(extract_file): Also invert S_IWUSR if it’s not set.
* tests/xattr08.at: New test.
* tests/Makefile.am, tests/testsuite.at: Add it.
2022-08-15 Paul Eggert <eggert@cs.ucla.edu>
Avoid quadratic behavior with delayed links
Do this by searching a hash table instead of a linked list.
Problem reported by Martin Dørum in https://mort.coffee/home/tar/
via Gavin Smith in:
https://lists.gnu.org/r/bug-tar/2022-07/msg00003.html
* src/extract.c: Include hash.h.
Improve performance a bit on non-birthtime hosts
(struct delayed_link.has_predecessor): New member.
(delayed_link_head): Remove, replacing with ...
(delayed_link_table): ... this new variable. All uses
of linked list replaced with hash table.
(dl_hash, dl_compare): New functions for hash table.
(create_placeholder_file): Initialize has_predecessor.
(apply_delayed_link): New function, with body taken from
most of the old apply_delayed_link.
(apply_delayed_links): Use it. Respect has_predecessor.
Don’t bother freeing as we are about to exit.
2022-08-15 Paul Eggert <eggert@cs.ucla.edu>
Improve performance a bit on non-birthtime hosts
* src/extract.c (HAVE_BIRTHTIME, BIRTHTIME_EQ): New macros.
(struct delayed_link, create_placeholder_file, extract_link)
(apply_delayed_links): Avoid unnecessary work on platforms
like GNU/Linux that lack birthtime.
2022-08-15 Paul Eggert <eggert@cs.ucla.edu>
Avoid excess lseek etc.
* src/buffer.c, src/delete.c: Do not include system-ioctl.h.
* src/buffer.c (guess_seekable_archive): Remove. This is now done
by get_archive_status, in a different way.
(get_archive_status): New function that gets archive_stat
unless remote, and sets seekable_archive etc.
(_open_archive): Prefer bool for boolean.
(_open_archive, new_volume): Get archive status consistently
by calling get_archive_status in both places.
* src/buffer.c (backspace_output):
* src/compare.c (verify_volume):
* src/delete.c (move_archive):
Let mtioseek worry about mtio.
* src/common.h (archive_stat): New global, replacing ar_dev and
ar_ino. All uses changed.
* src/delete.c (move_archive): Check for integer overflow.
Also report overflow if the archive position would go negative.
* src/system.c: Include system-ioctl.h, for MTIOCTOP etc.
(mtioseek): New function, which also checks for integer overflow.
(sys_save_archive_dev_ino): Remove.
(archive_stat): Now
(sys_get_archive_stat): Also initialize mtioseekable_archive.
(sys_file_is_archive): Don’t return true if the archive is
/dev/null
since it’s not a problem in that case.
(sys_detect_dev_null_output): Cache dev_null_stat.
doc: omit MS-DOS mentions in doc
It’s really FAT32 we’re worried about now, not MS-DOS.
And doschk is no longer a GNU program.
2022-08-15 Paul Eggert <eggert@cs.ucla.edu>
Omit MS-DOS mentions in doc

2022-07-25 Paul Eggert <eggert@cs.ucla.edu>
Work around GCC bug 106436
* src/tar.c (optloc_eq): Use ‘assume’ to pacify GCC bug.
2022-07-25 Paul Eggert <eggert@cs.ucla.edu>
Avoid unlikely crash when xasprintf returns 0
Problem caught by GCC 12.
* src/tar.c (easprintf): New static function, which never returns
a null pointer. All uses of xasprintf replaced by uses of this
function.
2022-07-25 Paul Eggert <eggert@cs.ucla.edu>
Update .gitignore
* .gitignore: Redo for current sources.
2022-07-25 Paul Eggert <eggert@cs.ucla.edu>
Fix minor type confusion
* src/tar.c (decode_options): Don’t assign ‘false’ to
a pointer.
2022-07-25 Paul Eggert <eggert@cs.ucla.edu>
Work around GCC bug 106428
* src/names.c (read_next_name): Reword and clarify
to avoid GCC bug 106428.
2022-07-25 Paul Eggert <eggert@cs.ucla.edu>
Work around GCC bug 106427
* lib/wordsplit.c (coalesce_segment): Reword to avoid
GCC bug 106427.
2022-07-24 Paul Eggert <eggert@cs.ucla.edu>
Adjust to Gnulib bootstrap revamp
* autogen.sh, autopull.sh, bootstrap-funclib.sh:
New files, copied from gnulib/top.
* bootstrap: Copy from gnulib/top/bootstrap (as opposed
to copying from gnulib/build-aux/bootstrap, as we used to).
* bootstrap.conf (bootstrap_post_pull_hook)
(bootstrap_post_import_hook): New functions.
Move commands into these functions as needed.
2022-07-11 Paul Eggert <eggert@cs.ucla.edu>
* doc/tar.1: Fix --xattrs-exclude typo.
2022-06-14 Paul Eggert <eggert@cs.ucla.edu>
Avoid EOVERFLOW problems in some symlink tests
* src/extract.c (is_directory_link): New arg ST. Caller changed.
(is_directory_link, open_output_file):
Use readlinkat, not fstatat, to determine whether a string
names a symlink. This avoids EOVERFLOW issues.
(extract_dir): Avoid duplicate calls to fstatat when
keep_directory_symlink_option && fstatat_flags == 0
and the file is a symlink to an existing file.
2022-06-14 Paul Eggert <eggert@cs.ucla.edu>
Fix ‘make dist-xz’ bug
Problem reported by Pavel Raiskup in:
https://lists.gnu.org/r/bug-tar/2022-06/msg00014.html

Fix doc -c typo
https://lists.gnu.org/r/bug-tar/2022-06/msg00006.html
* doc/tar.texi (Extended File Attributes): Fix typo.
2022-06-13 Paul Eggert <eggert@cs.ucla.edu>
Update to current Autoconf & Gettext
* acinclude.m4, configure.ac:
Use AS_HELP_STRING, not AC_HELP_STRING.
* bootstrap: Sync from Gnulib.
* configure.ac: Require Autoconf 2.71 and Gettext 0.21.
Use AC_PROG_CC, not AC_PROG_CC_STDC.
Prefer AC_COMPILE_IFELSE to AC_TRY_COMPILE.
Use AC_CONFIG_FILES.
* gnulib.modules: Use gettext-h, not gettext.
2022-06-13 Paul Eggert <eggert@cs.ucla.edu>
build: update gnulib and paxutils submodules to latest
2022-06-11 James Abbatiello <abbeyj@gmail.com> (tiny change)
tar: fix race condition
Problem reported in:
https://lists.gnu.org/r/bug-tar/2022-03/msg00000.html
* src/extract.c (make_directories): Retry the file creation as
long as the directory exists, regardless of whether tar itself
created the directory.
2022-06-11 Paul Eggert <eggert@cs.ucla.edu>
tar: fix race condition
Problem reported by James Abbatiello in:
https://lists.gnu.org/r/bug-tar/2022-03/msg00000.html
* src/extract.c (make_directories): Do not assume that when
mkdirat fails with errno == EEXIST that there is an existing file
that can be statted. It could be a dangling symlink. Instead,
wait until the end and stat it.
2022-06-11 Paul Eggert <eggert@cs.ucla.edu>
test: new test extrac25.at
* tests/Makefile.am (TESTSUITE_AT): Add extrac25.at.
* tests/extrac25.at: New file.
* tests/testsuite.at: Include it.
2022-06-10 Paul Eggert <eggert@cs.ucla.edu>
Warn “file changed as we read it” less often
* src/create.c (dump_file0): Remove an fstatat call that is
unnecessary because the file wasn’t read so we can treat
the first
fstatat as atomic. Warn “file changed” when the file’s
size,
mtime, user ID, group ID, or mode changes, instead of when the
file’s size or ctime changes. Also, when such a change happens,
do not change exit status if --ignore-failed-read. Finally,
don’t
attempt to change atime back if it didn’t change.

doc: fix abrupt sentence in HTML
Typo reported by Jackson Dougherty in:
https://lists.gnu.org/r/bug-tar/2022-05/msg00000.html
* doc/tar.texi: Don’t assume that tex and info are the only two
formats.
2022-02-16 Paul Eggert <eggert@cs.ucla.edu>
tar: revamp "file is the archive" diagnostic
* src/create.c (dump_file0): For clarity, change diagnostic
wording from "file is the archive; not dumped" to "archive cannot
contain itself; not dumped". All test cases and documentation
changed.

Add NEWS items for changes since 1.34
2021-12-13 Paul Eggert <eggert@cs.ucla.edu>
Omit unnecessary devmajor and devminor setting
* src/create.c (dump_file0): Omit redundant setting of devmajor
and devminor; start_header already does this.
2021-12-13 Paul Eggert <eggert@cs.ucla.edu>
Omit devmajor and devminor for non-special files
* src/create.c (start_header): Leave the devmajor and devminor
fields empty for files that are not character and block special
devices, even when the archive format is pax, ustar or v7.
This avoids generating irrelevant differences which helps with
reproducible builds, and is more compatible with what Solaris 10
tar does.
2021-12-13 Paul Eggert <eggert@cs.ucla.edu>
Use ‘bool’ in create.c
* src/create.c: Prefer ‘bool’, ‘true’, ‘false’

build: improve build-from-git for older GCCs
configure.ac: Bump GCC version from 4.6 to 11.2 when deciding
whether
to default to enabling GCC warnings when --enable-gcc-warnings
is not
specified, as older GCCs can generate too many false alarms. From
a suggestion by Christian Schoenebeck.
2021-09-19 Paul Eggert <eggert@cs.ucla.edu>
Simplify wordsplit code a bit
These changes pacify gcc -Wanalyzer-null-dereference on x86-64 gcc

Add _GL_ATTRIBUTE_MALLOC _GL_ATTRIBUTE_DEALLOC_FREE.
Problem found by gcc -Wsuggest-attribute=malloc and
current Gnulib.
2021-09-17 Paul Eggert <eggert@cs.ucla.edu>
Pacify gcc -Warray-parameter
* src/common.h (code_timespec): Declare sbuf arg to be an array,
to be consistent with definition.
2021-09-17 Paul Eggert <eggert@cs.ucla.edu>
Fix null rereference if low-memory
* src/incremen.c (read_incr_db_01): Use xstrdup not strdup.

Fix suggested by Anthony Heading.
* src/transform.c (_single_transform_name_to_obstack): Avoid
duplicating
initial prefix if replace is not needed.
2021-07-01 Samanta Navarro <ferivoz@riseup.net>
Fix crash on invalid command line argument
The copy_string_unquote function does not handle arguments
which only
consist of a single quote. A string is only quoted if two quoting
characters exist.
How to reproduce:

2021-07-01 Sergey Poznyakoff <gray@gnu.org>
Fix the use of options with trailing slash in files-from list
* src/names.c (read_name_from_file): Do not remove trailing slash
here, since name_buffer might contain an option (e.g. -C /).
(read_next_name): Remove trailing slash when we're sure we're
dealing
with a file name.
See 163e96a0.
2021-06-01 Sergey Poznyakoff <gray@gnu.org>
Minor fix
* scripts/backup-specs: Set standard paths for rsh (patch#9275).

Fix gendocs_template
2021-03-08 Paul Eggert <eggert@cs.ucla.edu>
Tune for single-threaded tar
This takes advantage of recent optimizations in Gnulib
for single-threaded programs.
* configure.ac (GNULIB_EXCLUDE_SINGLE_THREAD)
(GNULIB_MBRTOWC_SINGLE_THREAD, GNULIB_REGEX_SINGLE_THREAD)
(GNULIB_WCHAR_SINGLE_LOCALE): Define.
2021-03-08 Paul Eggert <eggert@cs.ucla.edu>
Port linking to AIX 7.1
* src/Makefile.am (LDADD): Remove, folding into tar_LDADD.
* src/Makefile.am (tar_LDADD), tests/Makefile.am (LDADD):
Add the libraries gnulib-tool currently recommends: LIB_ACL,
LIB_CLOCK_GETTIME, LIB_GETRANDOM, LIB_HARD_LOCALE, LIB_HAS_ACL,
LIB_MBRTOWC, LIB_SETLOCALE_NULL. Otherwise, tar won’t link
on AIX
7.1 with xlc because the -lpthread option is missing.
2021-03-08 Paul Eggert <eggert@cs.ucla.edu>
Port xattr-at.h to AIX 7.1
* lib/xattr-at.h: Include <errno.h> before testing whether
ENOATTR is defined.
2021-03-08 Paul Eggert <eggert@cs.ucla.edu>
build: update gnulib submodule to latest
2021-03-01 Sergey Poznyakoff <gray@gnu.org>
Fix building the online version of the manual.
* doc/Makefile.am (GENDOCS): Use the version from the tar
repository.
(manual): Set the DISTRIN rendition.
(manual-rebuild): New goal.
* doc/README.manual: New file. Instructions for maintainers on
how to
update web documentation.
* doc/gendocs.sh: A version from gnulib fixed as per
https://lists.gnu.org/archive/html/bug-gnulib/2021-03/msg00002.html.
* doc/gendocs_template: Updated version from gnulib.
* doc/intern.texi: Fix the use of UNREVISED.

2021-03-01 Paul Eggert <eggert@cs.ucla.edu>
Fix unlikely uninitalized var bug with sparse file
* src/sparse.c (sparse_extract_file): Set *SIZE to
stat.st_size so that the caller does not use *SIZE
when uninitalized. Problem found with GCC 10 and
--enable-gcc-warnings CFLAGS='-O2 -flto -fanalyzer'.
2021-03-01 Paul Eggert <eggert@cs.ucla.edu>
Pacify --enable-gcc-warnings -flto -fanalyzer
With GCC 10.2.1, ‘./configure --enable-gcc-warnings CFLAGS='-O2
-flto -fanalyzer' issued a false alarm about uninitialized
variable use. Pacify GCC by using a variant of the code.
* src/buffer.c (zip_program): Omit last placeholder entry.
(n_zip_programs): New constant.
(find_zip_program): Use it instead of placeholder.
(first_decompress_program): Set *PSTATE to maximum value
if skipping the table. This avoids confusing gcc -flto
into thinking *PSTATE is used uninitialized.
(next_decompress_program): Simplify now that *PSTATE is maximal
when skipping.
2021-03-01 Paul Eggert <eggert@cs.ucla.edu>
Pacify clang for unreachable ‘return’
* src/sparse.c (sparse_scan_file_seek): Omit unreachable
statement.
2021-03-01 Paul Eggert <eggert@cs.ucla.edu>
Pacify clang char conversion
* src/create.c (to_chars): Pacify ‘clang’ about assigning
128 to ‘char’.
2021-03-01 Paul Eggert <eggert@cs.ucla.edu>
Omit most uses of ‘inline’
With today’s compilers ‘inline’ is typically not needed for
performance (at least the way GNU Tar uses it) and it gets in the
way of portability.
* configure.ac: Omit AC_C_INLINE; no longer needed here.
* lib/attr-xattr.in.h (setxattr, lsetxattr, fsetxattr, getxattr)
(lgetxattr, fgetxattr, listxattr, llistxattr, flistxattr):
* lib/wordsplit.c (skip_delim_internal, skip_delim)
(skip_delim_real, exptab_matches):
* src/delete.c (flush_file):
* src/extract.c (safe_dir_mode):
* src/misc.c (ptr_align):
Now just static, not static inline.
* lib/wordsplit.h (wordsplit_getwords): Remove; no longer used.
* src/common.h (name_more_files): Now COMMON_INLINE, not
extern inline - which is not portable according to C99,
the way we were using it.
2021-03-01 Paul Eggert <eggert@cs.ucla.edu>
maint: port better to non-GCC compilers
This can be helpful in porting to compilers like Oracle Developer
Studio that support some but not all GCC attributes.
* lib/wordsplit.c (FALLTHROUGH): Remove; now done by attribute.h.
* lib/wordsplit.h (__WORDSPLIT_ATTRIBUTE_FORMAT): Remove;
all uses replaced by ATTRIBUTE_FORMAT.
* lib/wordsplit.h, src/buffer.c, src/common.h, src/compare.c:
* src/sparse.c, src/system.c, src/xheader.c:
Prefer ATTRIBUTE_FORMAT, MAYBE_UNUSED, _Noreturn, etc. to
__attribute__.

Update paxutils from upstream
2021-02-28 Paul Eggert <eggert@cs.ucla.edu>
maint: 1.34 announcement update
Hand-install 1.34 changes into master.
Evidently these changes were not pushed to savannah,
before I installed further changes today.
2021-02-28 Paul Eggert <eggert@cs.ucla.edu>
maint: port to Fedora 33
Fedora 33 uses GCC 10.2.1, which is a bit pickier.
* configure.ac: Do not use -Wsystem-headers, as this
runs afoul of netdb.h on Fedora 33.
* gnulib.modules: Add ‘attribute’.
* lib/wordsplit.c (wsnode_new): Return the newly allocated
pointer instead of a boolean, to pacify GCC 10.2.1 which otherwise
complains about use of possibly-null pointers. All uses changed.
* src/buffer.c (try_new_volume): Don’t assume find_next_block
succeeds.
(_write_volume_label): Pacify GCC 10.2.1 with an ‘assume’,
since
LABEL must be nonnull here.
* src/common.h (FALLTHROUGH): Remove; now in attribute.h.
Include attribute.h, for ATTRIBUTE_NONNULL.
* src/misc.c (assign_string_or_null): New function,
taking over the old role of assign_string.
(assign_string): Assume VALUE is non-null.
(assign_null): New function, taking over the old
role of assign_string when its VALUE was nonnull.
All callers of assign_string changed to use these functions.
(assign_string_n): Clear *STRING if VALUE is null,
to fix a potential double-free.

Related discussion in the Fedora pull-request:
https://src.fedoraproject.org/rpms/tar/pull-request/8
* tests/capabs_raw01.at: Newer systems (currently e.g. Fedora 34)
print getcap output in format CAP=VAL, not CAP+VAL.
2021-02-08 Sergey Poznyakoff <gray@gnu.org>
Gracefully handle duplicate symlinks when extracting
If the archive being extracted contains multiple copies
of the same symlink, extract only the first of them and
skip the rest. The use case is described in
https://lists.gnu.org/archive/html/bug-tar/2021-01/msg00026.html
The bug was introduced by 2d3396c3ea.
* src/extract.c (create_placeholder_file): If placeholder already
exists and is registered in the delayed_link list, return
immediately.

2021-01-14 Sergey Poznyakoff <gray@gnu.org>
Fixes in the delete_archive_members function
* src/delete.c (delete_archive_members): Clean-up the code. Avoid
entering the loop from the middle. Free the memory allocated for
current_stat_info.
2021-01-08 Sergey Poznyakoff <gray@gnu.org>
Use stdopen from gnulib
* gnulib.modules: Request stdopen
* lib/Makefile.am: Remove stdopen.c and stdopen.h
* lib/stdopen.c: Remove.

Bugfix --sparse --diff mode
Originally reported in:
https://bugzilla.redhat.com/show_bug.cgi?id=1853469
* src/sparse.c (check_data_region): Only compare the part
of buffer
really fed by safe_read(), not whole rdsize.
2020-06-24 Sergey Poznyakoff <gray@gnu.org>
Accept only position-sensitive (file-selection) options in file
list files.
Using such options as -f, -z, etc. is senseless in the file
list file
and bypasses the option consistency checks in decode_options.
Therefore,
only options related to file selection (a.k.a position-sensitive
options)
are allowed in files.
* doc/tar.texi: Document changes.
* src/common.h (tar_args): Move from tar.c
(TAR_ARGS_INITIALIZER): New macro.

(argp_children): New static variable.
(args): Remove static variable.
(more_options): Allow only options from names_argp.
(parse_default_options): Take a pointer to struct tar_args
as argument.
Replace the loc member during the call to argp_parse and
restore it
afterwards.
(decode_options): Use automatic variable for args.
2020-06-22 Sergey Poznyakoff <gray@gnu.org>
Fix the logic of prepare_to_extract.
* src/extract.c (prepare_to_extract): Return true to proceed with
the extraction, and false to skip the current member.
If extracting
over a pipe, skip unlinking logic.
(extract_archive): Update accordingly.
2020-06-15 Sergey Poznyakoff <gray@gnu.org>
Make sure link counting works for file names supplied with -T

* src/transform.c (parse_transform_expr):
Diagnose ‘--transform='s'’ instead of continuing past '\0'.
2020-02-15 Sergey Poznyakoff <gray@gnu.org>
Fix handling of linked rename chains in incremental backups
* src/incremen.c: Change the meaning of the DIRF_RENAMED flag.
Now it
marks a directory which is the last one in a chain of renames.
Regular renamed directories are recognized by their orig member
being
non-NULL. Directories marked with DIRF_RENAMED start encoding
of renames.
(procdir): Clear DIRF_RENAMED flag on directories which are
origins for
renames.
(makedumpdir): Use the orig member to check if the directory is a
result of a rename.
(store_rename): Move the check for DIR_IS_RENAMED to the
caller. Don't
clear the DIRF_RENAMED, it is not needed any more.
* tests/rename06.at: New test.
* tests/Makefile.am: Add rename06.at
* tests/testsuite.at: Likewise.

2020-02-08 Sergey Poznyakoff <gray@gnu.org>
Fix the --no-overwrite-dir option
Given this option, tar failed to preserve permissions of empty
directories
and to create files under directories owned by the current user
that did
not have the S_IWUSR bit set.
* src/extract.c (fd_chmod): Rename to fd_i_chmod.
(fd_chmod): New function.
(safe_dir_mode): New function.
(extract_dir): Special handling for existing directories in
--no-overwrite-dir mode.
* tests/extrac23.at: New file.
* tests/Makefile.am: Add new test case.

Fix extraction of symbolic links hardlinked to another symbolic
links
* src/extract.c (create_placeholder_file): Take additional
argument:
the delayed_link entry after which to the newly created one.
(extract_link): Create a placeholder file if the target link name
exists in the delayed_link list.
2019-04-11 Sergey Poznyakoff <gray@gnu.org>
Fix --delay-directory-restore on archives with reversed member
ordering.
* src/extract.c (find_direct_ancestor): Remove useless test.
(delay_set_stat): If the file name being added is already in
the list, update stored data instead of creating a new entry.
This works for archives with reversed order of members.
* tests/extrac22.at: New testcase.
* tests/Makefile.am: Add new testcase.
* tests/testsuite.at: Include new testcase.
2019-03-28 Sergey Poznyakoff <gray@gnu.org>

POSIX extended format headers do not include PID by default
The intent is to make binary-equivalent PAX archives easy
to create. If
POSIXLY_CORRECT is set, the POSIX standard default is used,
which embeds
the pid.
* src/common.h (posixly_correct): New global.
* src/tar.c (decode_options): Detect the POSIXLY_CORRECT
environment
variable.
* src/buffer.c (add_chunk_header): Change filenames of multipart
files to
omit the pid.
* src/xheader.c (HEADER_TEMPLATE): New macro.
(xheader_xhdr_name, xheader_ghdr_name): Use HEADER_TEMPLATE
to select
the template for the POSIX extended header name.

Ensure gnu format when running checkpoint tests
2019-01-14 Sergey Poznyakoff <gray@gnu.org>
Fix compression tests
Existing compression tests used tar with compiled-in
defaults. However,
some of the defaults are sure to create archives that are not
byte-to-byte
reproducible (e.g. DEFAULT_ARCHIVE_FORMAT=POSIX, because the
name field
in posix extended headers uses PID of the creating process
by default).
Moreover, some compressors (e.g. gzip) store current timestamp in
the file header when compressing from stdin, so that using cmp
on the
two created archives as the tests did is error-prone. Another
problem
is that the tests implicitly assumed that tar uses archive
suffix to
recognize its format when extracting, which isn't the
case. Finally,
there's hardly any reason in using sed to create m4 sources, when
everything can be achieved by m4 itself.
* tests/Makefile.am: Remove generation of compress-*.at files.
* tests/compress.at.in: Remove.
* tests/compress.m4: New file.
* tests/testsuite.at: Include compress.m4, use TAR_CHECK_COMPRESS
to
check compression options.

tests: fix numeric.at for BSD
While creating file, BSD kernels inherit the group ownership from
parent directory.
http://lists.gnu.org/archive/html/bug-tar/2016-06/msg00000.html

to proper group (at least on affected machines that command is
expected to succeed).

Fix expected output in dirrem tests.
In both tests, the "file changed as we read it" warning might be
produced for dir/sub, depending on the ctime resolution and
timing.
The problem was fixed by 64b43fdf70d82c39eb2ca900cd4f8e49,
but regressed
after e7cd377f7801d42aa8e07addff93d2150666c237, which removed
1 second
delays between each pair of checkpoints. Since the presense
or absense
of this warning is irrelevant for the test, it is now suppressed.
* tests/dirrem01.at: Suppress the file-changed warning.
* tests/dirrem02.at: Likewise.
2019-01-12 Sergey Poznyakoff <gray@gnu.org.ua>

Remove erroneous abort() call
The call was introduced by commit ccef8581. It caused tar to abort
on perfectly normal operations, like untarring archives containing
./ with the -U option,
See

for details.

Work over a bug in gnulib error()
The error() function from glibc correctly prefixes each message it
prints with program_name as set by set_program_name. However, its
replacement from gnulib, which is linked in on systems where this
function is not available, prints the name returned by
getprogname()
instead. Due to this messages output by tar subprocess (which
sets its
program name to 'tar (child)') become indiscernible from those
printed
by the main process. In particular, this breaks the remfiles01.at
and
remfiles02.at test cases.
* configure.ac: Define ENABLE_ERROR_PRINT_PROGNAME if using
gnulib error().
* src/tar.c [ENABLE_ERROR_PRINT_PROGNAME] (tar_print_progname):
New function.
(main) [ENABLE_ERROR_PRINT_PROGNAME]: Set error_print_progname.
2018-12-28 Sergey Poznyakoff <gray@gnu.org>
Implement the "wait" checkpoint action.
This action instructs tar to pause until given signal is

Disallow modifications to the global pax extended header in
update mode.
Updating global headers in update mode is not possible, because:
1) If the original archive was not in PAX format, writing the
global header would overwrite first member header (and eventually
data blocks) in the archive.
2) Otherwise, using the --pax-option can make the updated header
occupy more blocks than the original one, which would lead to the
same effect as in 1.
This also fixes

tests: fix race in dirrem01 and dirrem02
Previously the '--checkpoint-action=echo' was triggered after
'--checkpoint-action=sleep=1' - so the order of events *usually*
was (for --format='gnu'):
...
1. checkpoint handler before write of 'dir/sub' member
2. one-second delay
3. stderr write: 'tar: Write checkpoint 3'
4. write the member 'dir/sub' into the archive
5. check that the member's ctime has not been changed
6. genfile's detecting 'Write checkpoint', doing unlink
...
But sometimes, the genfile was fast enough to win the race and
unlinked the directory before the member was written into the
archive (IOW, the order was 1-2-3-6-4-5). This led to the
occasional warning 'tar: dir/sub: file changed as we read it'.
Swap the order of 'sleep=1' and 'echo' actions so the genfile
utility has (hopefully) enough time to do the unlink before
writing the file into the archive (enforce 1-2-3-6-4-5 order).
* tests/dirrem01.at: Swap 'sleep=1' and 'echo' actions.
* tests/dirrem02.at: Likewise.

Fix non-deterministic archive type detection
Due to analysis of partly uninitialized read-ahead buffer
(short_read call), we sometimes mistakenly classified very small
compressed archives as non-compressed; which in turn caused
extraction failure.

archives smaller than BLOCKSIZE could be non-compressed, as tar
header always has at least one block.

Fix a bug in multi-volume archive creation.
When creating multivolume archives, the bufmap code in buffer.c
implicitly assumed that the members are stored in the archive
contiguously, ignoring the member (and eventual extended) headers
between them. This worked until the member header happened to be
at the very beginning of the volume, in which case its length was
included in the calculation of the stored size and size left to
store. Due to this, the GNUFileParts extended header contained
invalid GNU.volume.offset value, and the resulting archive failed
to extract properly.
This patch also eliminates improper listing of file part headers
as regular files, when creating multivolume posix archives
with -v.
* src/buffer.c (bufmap): New member nblocks. Counts number
of blocks
of file data written since reset.
(bufmap_reset): Reset nblocks to 0.
(_flush_write): Update nblocks. When computing offset difference
for
bufmap_reset, count only data blocks, not headers.
(close_archive): Flush archive until all blocks are written.

finish_header
to avoid listing chunk header as regular file in verbose mode.
* tests/multiv10.at: New test case.
* tests/Makefile.am: Add new test.
* tests/testsuite.at: Add new test.

New option --clamp-mtime
The new `--clamp-mtime` option will change the behavior of
`--mtime` to only
use the time specified if the file mtime is newer than the
given time.
The `--clamp-mtime` option can only be used together with
`--mtime`.
Typical use case is to make builds reproducible: to loose less
information, it's better to keep the original date of an archive,
except for
files modified during the build process. In that case, using
a reference
(and thus reproducible) timestamps for the latter is good
enough. See
<https://wiki.debian.org/ReproducibleBuilds> for more information.

Fix handling of filename-selection options.
Filename-selection options are --wildcards, --recursive, etc. (see
names.c for a complete list). These options are
position-sensitive,
i.e. each such option affects all filenames and filename-selection
options that appear after it until eventually cancelled by a
corresponding counterpart option.
These options can appear in "file-from" file lists, which
means that
they cannot be handled right away, but instead should be put on
the "name_elt" list and processed sequentionally, as file name
arguments
are.

Fix problems caught by static checking
Most of these can be caught by configuring with
--enable-gcc-warnings.
Problem reported by Pavel Raiskup in:
http://lists.gnu.org/archive/html/bug-tar/2015-09/msg00001.html

Fill out incomplete initializers.
2015-08-31 Sergey Poznyakoff <gray@gnu.org>
Improve option sanity checking
Any two conflicting options are reported only if they both
occur in
the command line. Otherwise, options defined in the command line
silently override those set in the TAR_OPTIONS environment
variable.
* src/common.h (option_source): New enum.
(option_locus): New struct.
* src/names.c (name_elt): New member: line.
(name_add_file): Initialize line.

2015-08-03 Sergey Poznyakoff <gray@gnu.org.ua>
Options to control option handling in file lists.
The --verbatim-files-from option disables option handling in
file lists. The --no-verbatim-files-from reverts its effect.
The --null option implies --verbatim-files-from. This restores
the documented behavior, broken by 26538c9b.
* src/common.h (verbatim_files_from_option): New global.

tar: fix symlink race and symlink transform bug
Problem reported by Tobias Stoeckmann in:
http://lists.gnu.org/archive/html/bug-tar/2015-07/msg00004.html
* gnulib.modules: Add areadlinkat-with-size.
* src/create.c: Include areadlink.h.
(dump_file0): Use areadlinkat_with_size, rather than trying to do
it by hand, incorrectly. This also avoids assumption that
the symlink contents fit on the stack. Also, use the transformed
link name, not the original link name, when deciding whether the
name is long enough to require writing a long link.
2015-07-13 Paul Eggert <eggert@cs.ucla.edu>
tar: port -d to longer symlinks
* src/compare.c (diff_symlink):
Don't use alloca on symlink length; it might be too big for
the stack.
Don't assume that readlinkat's return value fits in 'int'.
Prefer memcmp to strncmp where either will do.
2015-07-13 Paul Eggert <eggert@cs.ucla.edu>
tar: port to recent gnulib

* lib/wordsplit.c (struct wordsplit_node.flags):
Now unsigned, so that 'printf ("%x", p->flags)' doesn't provoke
GCC.

Don't printf an int with %x or %o.
2015-04-16 Sergey Poznyakoff <gray@gnu.org.ua>
Fix extraction from concatenated incremental archives.
* src/common.h (remove_delayed_set_stat): New proto.

variable, as it will be deprecated in the next gzip release.
2015-02-19 Sergey Poznyakoff <gray@gnu.org.ua>
Improve compression format recognition
Some comressed archives can pass the checksum test, which
makes tar
treat them as uncompressed archives.
* src/buffer.c (check_compressed_archive): Test the checksum only
if the block we read looks like a valid tar header (i.e. has
a magic string).
2015-01-06 Paul Eggert <eggert@cs.ucla.edu>
tar: port xattr-at.c to Solaris 10
* lib/xattr-at.c (setxattrat, lsetxattrat, getxattrat,
lgetxattrat)
(listxattrat, llistxattrat): Compile only if HAVE_XATTRS, so that
the code doesn't call functions that are not declared.
2015-01-06 Paul Eggert <eggert@cs.ucla.edu>
tar: port wordsplit attribute to Sun C
Reported by Ted Carr in:
http://lists.gnu.org/archive/html/bug-tar/2015-01/msg00002.html

Fix bug in sparse file listing
List posix archives containing sparse files >8GB correctly and
do not fail.
This fixes also bug in format of listing for sparse files >8GB -
now the
real size is printed instead of the effective one (this is

posix format related).
* src/list.c: Remove redundant assignment.
* src/tar.h: Add new 'real_size' and 'real_size_set' fields in
tar_stat_info struct.

acls: bugfix for default ACLs extraction
When --acls option is on (regardless of tarball contents or
tarball format), we should explicitly set OR delete default ACLs
for extracted directories. Prior to this update, we always

Reduce memory consumption 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 malfunctioned
when given empty file lists or lists with the trailing newline
missing 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).

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.
* configure.ac (with_posix_acls): Fix misspellings.

tar: don't assume O_NONBLOCK is benign on regular files
On Data Migration Facility (DMF), High Performance 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.

tar: --owner and --group names and numbers
The --owner and --group options now accept operands of the form
NAME:NUM, so that you can specify both symbolic name and numeric
ID for owner and group. Also, in these options, NAME no longer
needs to be present in the current host's user and group
databases; this implements Debian enhancement request 136231
<http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=136231> reported

tar: simplify birthtime calculations
* src/extract.c (same_birthtime): Remove.
(extract_link, apply_delayed_links): Go back to using

relies
on an up-to-date gnulib.
2011-06-08 Paul Eggert <eggert@cs.ucla.edu>
tar: use birthtime rather than ctime when checking identity
Without this fix, tar would sometimes mishandle the extraction of
hard links to symbolic links. Problem reported in
<http://lists.gnu.org/archive/html/bug-tar/2011-06/msg00000.html>
by Andreas Stolcke.
* src/extract.c (struct delayed_link): Change ctime member

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.

(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.
* src/extract.c (extract_node): Do not mask out node type.
The bug was introduced in commit ea964cce.
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.

2010-10-27 Paul Eggert <eggert@cs.ucla.edu>
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 encountered".
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.
2010-10-26 Sergey Poznyakoff <gray@gnu.org.ua>
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>

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:

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

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>

* src/create.c: Adjust to set_file_atime signature change.
* src/extract.c (mark_after_links, file_newer_p, extract_dir):
Likewise.

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.
2010-09-19 Paul Eggert <eggert@cs.ucla.edu>
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.
2010-09-18 Paul Eggert <eggert@cs.ucla.edu>
tar: add utimens.h includes
* src/extract.c: Include <utimens.h>, needed for fdutimens
prototype.
* src/misc.c: Likewise.
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.
2010-09-17 Paul Eggert <eggert@cs.ucla.edu>
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.
2010-09-16 Paul Eggert <eggert@cs.ucla.edu>
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.
2010-09-16 Paul Eggert <eggert@cs.ucla.edu>
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 inadvertently.
* 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.
2010-09-13 Paul Eggert <eggert@cs.ucla.edu>
* NEWS: Fix wording typo in previous change.
Reported by Jim Meyering.
2010-09-13 Paul Eggert <eggert@cs.ucla.edu>
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.
2010-09-08 Paul Eggert <eggert@cs.ucla.edu>
tar: improve documentation of reliability and security issues
* doc/tar.texi (Reliability and security, Reliability):
(Permissions problems, Data corruption and repair, Race
conditions):
(Security, Privacy, Integrity, Live untrusted data):
(Security rules of thumb): New nodes.
2010-09-06 Paul Eggert <eggert@cs.ucla.edu>
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.
2010-09-05 Paul Eggert <eggert@cs.ucla.edu>
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.
2010-09-04 Paul Eggert <eggert@cs.ucla.edu>
tar: restore macros that are used in some cases
* 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.
2010-08-26 Paul Eggert <eggert@cs.ucla.edu>
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.
2010-08-26 Paul Eggert <eggert@cs.ucla.edu>
tar: fix bug with -C and delayed setting of metadata
* src/common.h (chdir_current): New decl.
* src/extract.c (struct delayed_set_stat, struct delayed_link):
New member change_dir.
(delay_set_stat, create_placeholder_file): Set it.
(apply_nonancestor_delayed_set_stat, apply_delayed_links): Use it.
(extract_link): Check that the links are all relative to the same
directory.
(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.
* tests/testsuite.at: Include it.
2010-08-25 Sergey Poznyakoff <gray@gnu.org.ua>
Don't apply file transformations to volume names.
* src/list.c (decode_header): Don't apply file transformations
to volume names.
* tests/xform01.at: New testcase.
* tests/xform-h.at (xform): Rename macro to xformtest. Use
pushdef/popdef.
* tests/Makefile.am, tests/testsuite.at: Add xform01.at
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):
(size_from_header): Remove decls.
* src/create.c (size_to_chars): Remove.
* src/list.c (size_from_header): Remove.
* src/sparse.c (sparse_extract_region, check_data_region):
(oldgnu_add_sparse, oldgnu_store_sparse_info, pax_decode_header):
Don't assume chunk sizes fit in size_t.
(oldgnu_add_sparse): Check for off_t overflow.
* src/xheader.c (sparse_numbytes_decoder, sparse_map_decoder):
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
* src/common.h (file_dumpable_p, gid_to_chars, major_to_chars):
(minor_to_chars, mode_to_chars, uid_to_chars, uintmax_to_chars):
(string_to_chars, dumpdir_creat0, dumpdir_create, dumpdir_free):
(dumpdir_locate, dumpdir_next, dumpdir_first, gid_from_header):
(major_from_header, minor_from_header, mode_from_header):
(time_from_header, uid_from_header, quote_copy_string,
request_stdin):
(xheader_init, transform_header_name):
Remove declarations; these are no longer exported from their
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):
Move to src/extract.c, since no other module uses these.

2010-08-19 Paul Eggert <eggert@cs.ucla.edu>
tar: update licenses to latest versions from www.gnu.org
* COPYING: Update to latest version; this is just minor
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/testsuite.at: Include it.
* tests/Makefile.am (TESTSUITE_AT): Add it.
2010-07-18 Paul R. Eggert <eggert@cs.ucla.edu>
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 // != /.
2010-07-17 Sergey Poznyakoff <gray@gnu.org.ua>
Allow for size suffixes in -L and --record-size options.
* src/tar.c (TAR_SIZE_SUFFIXES): New define.

2010-07-15 Paul R. Eggert <eggert@cs.ucla.edu>
tar: don't crash if getcwd fails
* src/extract.c: Don't include xgetcwd.h.
(extract_dir): stat "." rather than statting getcwd's output.
* src/misc.c (normalize_filename_x): Rewrite so as not to resolve
/../, 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.
* tests/Makefile.am (TESTSUITE_AT): Add listed03.at.
* tests/listed03.at: New file.
* tests/testsuite.at: Include listed03.at.
2010-07-11 Sergey Poznyakoff <gray@gnu.org.ua>

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

* 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

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'.

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>.

systems /dev/zero is not available.
2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
* NEWS: Fix some race conditions with tar -x --same-owner.
* src/extract.c (ARCHIVED_PERMSTATS): Add a comment saying that
S_IRWXG | S_IRWXO might be masked out.
(set_mode): Set the mode if some bits were masked out originally.

grant permissions that we don't want to grant. The chmod was
there only to work around broken hosts, so add a comment advising
users not to use those broken hosts instead.
(repair_delayed_set_stat, extract_dir):
Remember to mask out current umask before inverting permissions.
(extract_dir): If the owner might change, or if the mode has
special bits, create the directory 700 at first, but restore it later.

change, omit group and other bits at first, but restore them after
changing the owner.

Port to latest gnulib. There were a lot of changes, so the
simplest way to get this up and running was to switch to coreutils
bootstrap procedure. I noticed one feature missing after this

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.

* 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 carefully.
(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.

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.

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".

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.

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/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/Makefile.am: Added append01.at
* tests/testsuite.at: Likewise
2005-02-06 Sergey Poznyakoff <gray@Mirddin.farlep.net>

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.

* tests/listed01.sh: Give credit to Andreas Schuldei.
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

* src/incremen.c: Minor stylistic fixes.
* tests/listed01.sh: New test. Check listed incremental
backups on individual files.

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.
(decode_options): New option --show-defaults displays the
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.

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.

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
files.
2002-09-30 Paul Eggert <eggert@twinsun.com>
* src/rmt.c (prepare_input_buffer): Renamed form
prepare_record_buffer. All uses changed. Do not assume that
size_t is the same width as int.
2002-03-29 Paul Eggert <eggert@twinsun.com>
* src/incremen.c (get_directory_contents):
If ignore_failed_read_option, only warn about

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.

read more than 1 block. Handle resulting HEADER_SUCCESS_EXTENDED code.
Keep track of how many records have been skipped.
Let the buffer code count records.
When copying a header, copy any extended headers that came before it.
* src/extract.c (extract_archive): When marking a directory to be
updated after symlinks, stat all directories after it in the
delayed-set-stat list too, since they will be checked after
symlinks. Add support for --overwrite-dir.
* src/list.c (recent_long_name, recent_long_link,
recent_long_name_blocks, recent_long_link_blocks): New vars.
(read_and): Pass 0 to read_header.

2001-09-20 Jim Meyering <meyering@lucent.com>
* lib/xstrtol.c (strtoimax): Guard declaration with
`#if !HAVE_DECL_STRTOIMAX', rather than just `#ifndef strtoimax'.
The latter fails because some systems (at least rs6000-ibm-aix4.3.3.0)
have their own, conflicting declaration of strtoimax in sys/inttypes.h.
(strtoumax): Likewise, for completeness (it wasn't necessary).
* m4/xstrtoimax.m4 (jm_AC_PREREQ_XSTRTOIMAX):
Check for declaration of strtoimax.

* src/extract.c (struct delayed_set_stat): New member
'after_symlinks'.

(set_mode): New arg current_stat_info. Use it (if nonnull) to avoid
taking an extra stat ourselves. All callers changed.
(set_stat): Likewise.
(apply_nonancestor_delayed_set_stat): New arg 'after_symlinks'.
If false, stop when encountering a struct whose 'after_symlinks'
member is true. Otherwise, go through all structures but check
them more carefully. All callers changed.
(extract_archive): When extracting a deferred symlink, if its parent
directory's status needs fixing, then mark the directory as needing
to be fixed after symlinks.
(extract_finish): Fix status of ordinary directories, then apply
delayed symlinks, then fix the status of directories that are
ancestors of delayed symlinks.
* src/rtapelib.c (rexec):
Remove declaration; it ran afoul of prototypes on Crays.
Reported by Wendy Palm of Cray.

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

no-wildcard case.
* lib/xgetcwd.c: Include pathmax.h if not HAVE_GETCWD.
Do not include xalloc.h.
(INITIAL_BUFFER_SIZE): New symbol.
Do not use xmalloc / xrealloc, since the caller is responsible for
handling errors. Preserve errno around `free' during failure.
Do not overrun buffer when using getwd.
* lib/xgetcwd.c (xgetcwd):
Use HAVE_GETCWD_NULL, not defined __GLIBC__ && __GLIBC__ >= 2,
to decide whether to use getcwd (NULL, 0).
2001-09-02 Paul Eggert <eggert@twinsun.com>
* lib/xgetcwd.c: Fix typo in local var; from Jim Meyering.
2001-09-01 Jim Meyering <meyering@lucent.com>

* 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>

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>

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.

"\"") 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
2000-04-18 Paul Eggert <eggert@twinsun.com>
* m4/mbstate_t.m4: New file.
2000-04-17 Bruno Haible <haible@clisp.cons.org>

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.
(quotearg_buffer_restyled): Use it.
2000-02-23 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
* src/list.c (tartime): Fix off-by-one error when copying year if

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.
2000-01-11 Paul Eggert <eggert@twinsun.com>
* lib/exclude.c (FILESYSTEM_PREFIX_LEN, ISSLASH): Remove unused macros.

* 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.
(long_options, usage, decode_options): New --overwrite option.

(main): Set default quoting style to escape_quoting_style.
* src/update.c (<quotearg.h>): New include.
(append_file):
Don't assume that gettext preserves errno.
Quote arbitrary strings in diagnostics.
Check for close error.
* src/names.c (<quotearg.h>): New include.
(name_init, name_next, name_close, names_notfound,
collect_and_sort_names): Don't assume that gettext preserves
errno. Quote arbitrary strings in diagnostics.
(excluded_name): Fix typo that caused empty patterns to be
mishandled.
* src/misc.c (<quotearg.h>): New include.
(quote_copy_string): Quote only newline and backslash; the output is no
longer meant for humans, and is locale-independent.
(contains_dot_dot): New function.
(remove_any_file): Don't use lstat; just rmdir the file and then use
unlink if the rmdir fails because the file isn't a directory.
Check for readdir and closedir errors.
(maybe_backup_file): Report "stat" for stat errors.
(maybe_backup_file, chdir_do):
Quote arbitrary strings in diagnostics.
(maybe_backup_file, undo_last_backup):
Don't assume that gettext preserves errno.

mknod_error, open_error, open_fatal, open_warn, opendir_error,
opendir_warn, read_error, read_fatal, readdir_error, readdir_warn,
readlink_error, readlink_warn, seek_error, seek_warn, stat_error,
stat_warn, truncate_error, truncate_warn, unlink_error, waitpid_error,
write_error, write_fatal, xfork, xpipe, quote_n, quote): New functions.
* src/system.h (__attribute__): New macro.
(O_NDELAY, O_NONBLOCK, O_APPEND): Remove.
(S_ISDOOR): New macro.
(closedir): New macro, if CLOSEDIR_VOID.
* src/rmt.c, src/rtapelib.c (decode_oflag):

(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.

(make_directories): Avoid mkdir where last part of path is "..".
Create a struct delayed_set_stat for each directory made.
(prepare_to_extract): Renamed from unlink_destination, and
return 0 immediately if to_stdout_option; all callers changed.
(maybe_recoverable): New parameter interdir_made.
Add support for --overwrite.
(extract_sparse_file, extract_archive):
Quote arbitrary strings in diagnostics.
(extract_archive): By default, warn about ".." in member names, and skip them.
Don't open files with O_NONBLOCK or O_APPEND.
Open with O_TRUNC only if --overwrite; otherwise, use O_EXCL to avoid
overwriting them. Pass only rwxrwxrwx permissions to `open' and `mkdir',
minus the current umask. Keep track of intermediate directories made,
to avoid looping when making x/../x when x doesn't exist; the
earlier code solved this in a different way that didn't fit well
into the new scheme. Don't extract permissions onto existing
directories unless --overwrite is given. Do not add -wx------
permissions to new directories permanently; just do it temporarily.
Remove no-longer-needed hack with MSDOS and directory time stamps.
(apply_delayed_set_stat): New argument specifies which directories to
fix statuses of. Do not wait until the end of extraction to fix
statuses; instead, fix a directory's status once we exit that directory.
This requires less memory and does the right thing in some cases
where the old method didn't.
(fatal_exit): New function.
* src/incremen.c (<quotearg.h>): New include.
(get_directory_contents, gnu_restore):
Check for readdir and closedir errors.

`archive names'. Warn about `..' in member names.
(finish_sparse_file, dump_file):
Quote arbitrary strings in diagnostics.
(finish_sparse_file, dump_file):
Don't assume that gettext preserves errno.
(dump_file): Don't use `access' to determine whether a directory is readable;
this isn't reliable if tar is setuid. Use `opendir' instead.
Check for readdir and closedir failures.
Don't dump sockets as if they were fifos; just warn and skip.
* src/delete.c (move_archive):
Don't report fatal error merely because sizes don't fit
into struct mtop values; fall back on lseek instead.
Say `Cannot' uniformly, instead of `Could not' sometimes and `Cannot' others.
Say `reposition' instead of `re-position'.
(delete_archive_members):
Set archive to STDOUT_FILENO before outputting trailing buffer.
* src/compare.c (<quotearg.h>): New include.
(diff_init): Use `Cannot' uniformly, instead of `Could not' sometimes
and `Cannot' others.
(report_difference, diff_archive):
Quote arbitrary strings in diagnostics.
(process_rawdata, diff_sparse_files, get_stat_data, diff_archive, seek_warn):
Don't assume that gettext preserves errno.
(diff_archive): Don't open regular files with O_NONBLOCK.
Preserve access times of files if --atime.
* src/common.h (FATAL_ERROR): Use new fatal_exit function to exit.

(fatal_exit, contains_dot_dot, chdir_fatal, close_error,
closedir_error, exec_fatal, mkfifo_error, mknod_error, open_error,
open_fatal, open_warn, opendir_error, opendir_warn, read_error,
read_fatal, readdir_error, readdir_warn, readlink_error,
readlink_warn, seek_error, seek_warn, stat_error, stat_warn,
truncate_error, truncate_warn, unlink_error, waitpid_error,
write_error, write_fatal, xfork, xpipe, quote, quote_n): New decls.
* src/buffer.c:
(xclose, xdup2, child_open_for_compress, child_open_for_uncompress,
archive_write_error, archive_read_error, flush_archive, close_archive,
init_volume_number, new_volume):
Don't assume that gettext preserves errno.
(xdup2): Don't report errno if dup returns an unexpected nonnegative value.
(open_archive): Reject multivolume verify attempts a bit earlier.
Rename local variable `access', in case it's defined by system header.
(open_archive, backspace_output): Use `Cannot' uniformly, instead of
`Could not' sometimes and `Cannot' others.
(open_archive, flush_read, flush_archive, close_archive, new_volume):
Quote arbitrary strings in diagnostics.
(read_error): Set archive to STDOUT_FILENO temporarily when writing
archive buffer.
(init_volume_number): Check for input and output errors in volno_file.
(new_volume): Use new fatal_exit function to exit, and new xfork
function to fork.

defined if ! (HAVE_MBRTOWC && HAVE_WCHAR_H).
(quotearg_buffer_restyled): New function, with most of the old
quotearg_buffer's contents.
Major rewrite to support multibyte characters.
(quotearg_buffer): Now just calls quotearg_buffer_restyled.
* m4/c-bs-a.m4: New file.
* lib/Makefile.am: Use ## for copyright notice.
* scripts/Makefile.am: Use ## on copyright notice.

* 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.

Instead, always link fnmatch.h to some file, even if it's a throwaway.
1999-11-19 Paul Eggert <eggert@twinsun.com>
* m4/largefile.m4: Update serial.
1999-11-18 Paul Eggert <eggert@twinsun.com>
* m4/largefile.m4 (AC_SYS_LARGEFILE_FLAGS): Work around a bug in

as getting time can cause duplicate diagnostics if bogus.
Remove "Hmm, " from diagnostic.
Use "Skipping to next header" uniformly.

Allow different forms for unportable 2's complement numbers.
Don't check for extended forms when parsing checksums.

(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).

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):

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_to_oct, uid_to_oct): Use them as substitutes.
(finish_header): Do not assume that UINTMAX_TO_OCT appends a space.

* 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.

* 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.

cached_no_such_uid, cached_no_such_gid): New vars.
(uid_to_uname, gid_to_gname, uname_to_uid, gname_to_gid):
Cache failures, too.
* src/tar.c (decode_options):
Don't pass names longer than UNAME_FIELD_SIZE to
uname_to_uid, as it messes up the cache. Similarly for gname_to_uid.

Set to appropriate values if large file support
needs explicit enabling.
(HAVE_INTTYPES_H, HAVE_ST_FSTYPE_STRING, daddr_t, major_t, minor_t,

const char *. Size arg is now size_t. Now takes new type and maxval
args. Compute result using uintmax_t, not long. Report error if
field does not contain octal number in range.

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.
