Define environment variable TARTEST_SKIP_LARGE_FILES=1 in order
to skip tests that require lots of disk space.
* tests/testsuite.at (AT_SKIP_LARGE_FILES): New macro.

file, if --verbatim-files-from option is in effect.
(names_options): improve description of --verbatim-files-from

hard link name prior to transforming it.

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.

(names_options): Fix declaration of the
add-file option.

* src/tar.c (struct tar_args): Remove the input_files member.
Change all uses: use name_more_files() instead.
* tests/Makefile.am: Add new test.
* tests/add-file.at: New testcase.
* tests/testsuite.at: Add new test.
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';
this caused that modified 'path' header won and that is not what
we want in sparse "capable" tar implementation.
* src/tar.h (tar_stat_info): New argument sparse_name_done.
* src/xheader.c (raw_path_decoder): Move here the unconditional
code from path_decoder.
(path_decoder): Apply raw_path_decoder only if sparse_path_decoder
was not yet called.
(sparse_path_decoder): New wrapper around raw_path_decoder.
* tests/sparse07.at: New testcase.
* tests/testsuite.at: Mention new testcase.
* tests/Makefile.am: Likewise.
This makes archive create behavior consistent with the
documentation. Without this change xattr include/exclude options
are accepted when creating an archive but are silently ignored.
* src/xattrs.c (xattrs_xattrs_get): Apply exclude/include mask
when fetching extended attributes
* tests/Makefile.am: Add new test case.
* tests/testsuite.at: Likewise.
* src/names.c (file_selection_option)
(file_selection_option_name): New functions.
(unconsumed_option_push, unconsumed_option_free)
(unconsumed_option_report): New functions.

of eventually unconsumed options during archive creation.
Report unconsumed options, if any.

* tests/positional02.at: New test case.
* tests/positional03.at: New test case.
* tests/Makefile.am: Add new test cases.
* tests/testsuite.at: Likewise.
* NEWS: Document the changes.
* configure.ac: Version 1.29.90
* doc/tar.texi: Document the changes.
The auxiliary utility ttyemu proved to be unreliable. Given existing
differences between pty implementations and termios ioctls on various
platforms, writing it in a portable way requires effort disproportional
to its actual purpose.
* configure.ac: Remove check for grantpt
* gnulib.modules: Remove posix_openpt, ptsname, and unlockpt
* tests/Makefile.am (TESTSUITE_AT): Remove iotty.at
(check_PROGRAMS): Remove ttyemu.
* tests/testsuite.at: Remove iotty.at
* tests/iotty.at: Remove.
* tests/ttyemu.c: Remove.
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.

mounted, current LA and lots of other factors, creation of archive can
take much more time than the expected 2 seconds.
* paxutils: Update.
* src/unlink.c (flush_deferred_unlinks): OpenSolaris sets EEXIST
instead of ENOTEMPTY if trying to remove a non-empty directory.

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.

correctly together with --{,no-}recursion.
* tests/Makefile.am: Mention new test T-recurse.at.
* tests/testsuite.at: Likewise.
* src/list.c (simple_print_header): Do not parse ustar header
for UID/GID again (tar_stat_info has already been correctly
filled with respect to possible uid/gid extended headers).
* tests/numeric.at: New testcase for --numeric-owner option.
* tests/Makefile.am: Add new testcase.
* tests/testsuite.at: Likewise.
Based on patch by Pavel Raiskup.

* src/buffer.c (write_fatal_details): Close the archive and wait for
the compressor program to terminate in order to catch eventual execution
errors.

not silently terminate when unable to write to the compressor.
* tests/comperr.at: New file.
* tests/Makefile.am: Add comperr.at
* tests/testsuite.at: Include comperr.at
When extracting an archive that contains './' with the --one-top-level option,
the mode and ownership of '.' would be incorrectly applied to the current
working directory, instead of the requested top-level directory.
* src/list.c (enforce_one_top_level): Map '.' to the top-level
directory.
* tests/Makefile.am: Add onetop05.at

at the first pass. If force is requested, run a second pass
removing them.

entries are sorted in descending order by the value of dir_idx.
This makes sure they will be removed in right order, which works
around unlinkat bug on FreeBSD and GNU/Hurd.
* tests/remfiles08b.at: Remove expected failure.
* tests/remfiles09b.at: Likewise.
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.
