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.

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.
* doc/tar.texi: Fix description of the argument to --xattrs-exclude
and --xattrs-include option. It is a globbing pattern, not a regex.
Fix a typo (LZOP)
* src/names.c (file_selection_option)
(file_selection_option_name): New functions.
(unconsumed_option_push, unconsumed_option_free)
(unconsumed_option_report): New functions.
(name_list_advance): Maintain a list
of eventually unconsumed options during archive creation.
Report unconsumed options, if any.
* tests/positional01.at: New test case.
* 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.
* src/system.c (xexec): Use sh -c to run the command. This fixed
bug introduced by 7b5e80396 (tar 1.27)
* doc/tar.texi: Fix checkpoint examples: (1) $TAR_FILENAME
is not available when creating archive and (2) --checkpoint
can't be used as abbreviation of --checkpoint-action
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.

all members.
Based on patch by Pavel Raiskup.
Use SEEK_HOLE/SEEK_DATA feature of lseek on systems that support
it. This can make archiving of sparse files much faster.
Implement the --hole-detection option to allow users to select
hole-detection method.
* src/common.h (hole_detection_method): New enum.
(hole_detection): New global.
* src/sparse.c (sparse_scan_file_wholesparse): New function as a
method for detecting sparse files without any data.
(sparse_scan_file_raw): Rename from sparse_scan_file; with edits.
(sparse_scan_file_seek): New function.
(sparse_scan_file): Reimplement function.
* src/tar.c: New option --hole-detection
* tests/checkseekhole.c: New file.
* tests/.gitignore: Mention two test binaries.
* tests/Makefile.am: Add new tests.
* tests/testsuite.at (AT_SEEKHOLE_PREREQ): New macro.
Include sparse06.at.
* tests/sparse06.at: New test case.
* tests/sparse02.at: Force raw hole-detection method.
* tests/sparsemv.at: Likewise.
* tests/sparsemvp.at: Likewise.
* doc/tar.1: Document --hole-detection option.
* doc/tar.texi: Document hole-detection algorithms and
command-line options.
* NEWS: Document hole-detection.
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.
* src/names.c (name_elt): New member: file.verbatim
(name_add_file): Take 'verbatim' state as its third parameter.
(read_next_name): Don't call handle_option if file.verbatim
is set.
* src/tar.c: New options --verbatim-files-from and
--no-verbatim-files-from.
* doc/tar.texi: Document --verbatim-files-from and
--no-verbatim-files-from options.
* NEWS: Update.

* tests/testsuite.at: Update.
Changes proposed by Denis Excoffier.
* NEWS: Fix typos.
* doc/tar.texi: Fix typos. Improve recipe for creation of binary
equivalent archives.
* src/create.c (write_extended): Use the value of the
--mtime option (if specified) as the default for exthdr.mtime.
* src/xheader.c (xheader_store): Create the header if at least
one override is supplied in --pax-option.
