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

* 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.

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.

* 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>
Update copyright years
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.

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>

Typesetting fixes in the manpage
2019-03-28 Zachary Vance <za3k@za3k.com>
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.
* doc/tar.texi: Document the change.
2019-03-03 Sergey Poznyakoff <gray@gnu.org>
Check return value from xgetcwd
* src/misc.c (chdir_arg,tar_getcdpath): Check for non-NULL

in commit
67cad0792b4e6cf22c6cb1b167b149cd176d49f9.
2019-01-15 Sergey Poznyakoff <gray@gnu.org>

Version 1.31.90
2019-01-14 Sergey Poznyakoff <gray@gnu.org>
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.
2019-01-14 Sergey Poznyakoff <gray@gnu.org>
Fix possible NULL dereference (savannah bug #55369)
* src/sparse.c (pax_decode_header): Check return from
find_next_block.
2019-01-14 Sergey Poznyakoff <gray@gnu.org>
Fix compilation without iconv.
2019-01-14 Sergey Poznyakoff <gray@gnu.org>
Fix iconv usage.
Patch by Christian Weisgerber.
* src/utf8.c (utf8_convert): non-zero return from iconv means
failure.
2019-01-14 Pavel Raiskup <praiskup@redhat.com>
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
* tests/numeric.at: Attempt to 'chown' the newly created directory
to proper group (at least on affected machines that command is
expected to succeed).
2019-01-14 Sergey Poznyakoff <gray@gnu.org>
Fix typo in manpage.
2019-01-14 Sergey Poznyakoff <gray@gnu.org>
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>
Fix the use of --checkpoint without explicit --checkpoint-action
* src/checkpoint.c (checkpoint_finish_compile): Set default
action,
if necessary.
* tests/checkpoint/defaults.at: New testcase.
* tests/checkpoint/dot-compat.at: New testcase.
* tests/checkpoint/dot-int.at: New testcase.
* tests/checkpoint/dot.at: New testcase.
* tests/checkpoint/interval.at: New testcase.
* tests/Makefile.am: Add new testcases.
* tests/testsuite.at Include new testcases.
2019-01-10 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
http://lists.gnu.org/archive/html/bug-tar/2019-01/msg00019.html
for details.
* src/extract.c (maybe_recoverable): Remove misplaced call
to abort().
2019-01-02 Sergey Poznyakoff <gray@gnu.org>
Version 1.31
2018-12-28 Sergey Poznyakoff <gray@gnu.org>
Fix the difflink test
Hardlinking a symlink produces hardlink on BSD and symlink
on GNU/Linux. Avoid the ambiguity.
* tests/difflink.at: Create hard link from a regular file.
2018-12-28 Sergey Poznyakoff <gray@gnu.org>
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
delivered.
The newer genfile tool uses this action for communication between
genfile and tar in exec mode. This eliminates race conitions and
speeds up the tests based on exec mode.
* doc/tar.texi: Document changes.
* paxutils: Upgrade.
* src/checkpoint.c: Implement the wait action.
* src/common.h (decode_signal): New proto.
* src/tar.c (decode_signal): New function.
(set_stat_signal): Rewrite.

to use the new feature.
* tests/dirrem02.at: Likewise.

* tests/testsuite.at: Likewise.
* tests/sptrcreat.at: New file.
* tests/sptrdiff00.at: New file.
* tests/sptrdiff01.at: New file.
2018-12-21 Sergey Poznyakoff <gray@gnu.org>
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
http://lists.gnu.org/archive/html/bug-tar/2018-12/msg00007.html
* src/xheader.c (xheader_forbid_global): New function.
* src/common.h (xheader_forbid_global): New prototype.
* src/update.c (update_archive): Use xheader_forbid_global,
instead
of trying to write global extended header record.

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

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.
(add_chunk_header): Use simple_finish_header instead of
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.

sparse: fix pax extraction for unicode filenames
Make sure that 'GNU.sparse.name' header has higher priority than

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.

Minor fix
2015-12-11 Sergey Poznyakoff <gray@gnu.org>
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.
* src/common.h (warn_regex_usage): Remove.
(name_add_name): Change signature.

Fix bug in the inplementation of --one-top-level.
When extracting an archive that contains './' with the

at the first pass. If force is requested, run a second pass
removing them.
(queue_deferred_unlink): Make sure current working directory
entries are sorted in descending order by the value of dir_idx.
This makes sure they will be removed in right order, which works

Improve option sanity checking
Any two conflicting options are reported only if they both

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>

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.

Fix bug in sparse file listing
List posix archives containing sparse files >8GB correctly and

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.
