Version 1.32
2019-02-04 Sergey Poznyakoff <gray@gnu.org>

Fix typos in the documentation
Short option "t" was mistranslated to "--test" instead of "--list"
in commit
67cad0792b4e6cf22c6cb1b167b149cd176d49f9.
2019-01-15 Sergey Poznyakoff <gray@gnu.org>
Fix build on AIX
* src/unlink.c (flush_deferred_unlinks): Avoid possible duplicate
case

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.
* tests/dirrem01.at: Adjust genfile and tar command line arguments
to use the new feature.

* 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

* 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.

by #).
Strip comments and horizontal tabs prior to storing ACLs in PAX
headers.
* src/xattrs.c (xattrs_acls_cleanup): New function.
(xattrs__acls_get_a,xattrs__acls_get_d): Use xattrs_acls_cleanup.
2018-11-24 Sergey Poznyakoff <gray@gnu.org>

Without this change, some ASAN-enabled test runs would fail
with the
following. Also, strip an additional .tar suffix only if
the just-
stripped suffix did not match /^\.t/".

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.
