2019-02-23  Sergey Poznyakoff  <gray@gnu.org>

	Version 1.32

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

	Minor fixes in docs.

	* doc/tar.1: Remove description of the --preserve option
	Document verbosity levels.
	* doc/tar.texi: Fix description of the -o option.

2019-01-15  Daniel Le  <greenrecyclebin@gmail.com>

	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
	(if ENOTEMPTY==EEXIST)

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.
	* tests/dirrem01.at: Adjust genfile and tar command line arguments
	to use the new feature.
	* tests/dirrem02.at: Likewise.
	* tests/filerem01.at: Likewise.
	* tests/filerem02.at: Likewise.
	* tests/grow.at: Likewise.
	* tests/sptrcreat.at: Likewise.
	* tests/sptrdiff00.at: Likewise.
	* tests/sptrdiff01.at: Likewise.
	* tests/truncate.at: Likewise.

2018-12-27  Sergey Poznyakoff  <gray@gnu.org>

	Fix CVE-2018-20482

	* NEWS: Update.
	* src/sparse.c (sparse_dump_region): Handle short read condition.
	(sparse_extract_region,check_data_region): Fix dumped_size
	calculation.
	Handle short read condition.
	(pax_decode_header): Fix dumped_size calculation.
	* tests/Makefile.am: Add new testcases.
	* 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.

2018-12-21  Sergey Poznyakoff  <gray@gnu.org>

	Bug reported in
	  http://lists.gnu.org/archive/html/bug-tar/2018-12/msg00014.html

	* src/names.c (collect_and_sort_names): Fix iteration over
	namelist.

2018-12-21  Sergey Poznyakoff  <gray@gnu.org>

	Fix semantics of -K used together with explicit member names.

	This also fixes the bug reported in
	  http://lists.gnu.org/archive/html/bug-tar/2018-12/msg00012.html

	* src/common.h (starting_file_option): Describe the variable.
	* src/names.c (add_starting_file): New function.
	(name_match): Ignore everything before the member indicated by the
	--starting-file option
	* src/tar.c: Use add_starting_file to handle the -K option.

2018-12-21  Sergey Poznyakoff  <gray@gnu.org>

	Fix error handling when reading incremental snapshots

	Bug reported in
	  http://lists.gnu.org/archive/html/bug-tar/2018-12/msg00008.html

	to find_backup_file_name.  This fixes a bug whereby the wrong
	backup file name was chosen for numbered backups.

2018-10-29  Paul Eggert  <eggert@cs.ucla.edu>

	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.

	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.

2017-05-29  Sergey Poznyakoff  <gray@gnu.org.ua>

	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.

	sparse: fix pax extraction for unicode filenames

	Make sure that 'GNU.sparse.name' header has higher priority than
	(for sparse-purposes artificially modified) 'path' pax header.

	Historically, the 'GNU.sparse.name' header comes before 'path';

	we want in sparse "capable" tar implementation.

	when fetching extended attributes
