(In response to savannah bug #63574)
* doc/intern.texi: Document actual tar behaviour in regard to
missing end-of-file marker.
* doc/tar.texi: Rewrite the "warnings" section. Document
--warning=missing-zero-blocks
* src/common.h (WARN_MISSING_ZERO_BLOCKS): New constant.
(WARN_ALL): Include all warning bits.
* src/list.c (read_and): If EOF is reached without seeing end-of-file
blocks and the "missing-zero-blocks" warning is requested, warn about
the fact.
* src/warning.c: New warnings: "missing-zero-blocks", "verbose".
(warning_option): Change definition to reflect changes in common.h
* src/create.c (dump_file0): Remove an fstatat call that is
unnecessary because the file wasn’t read so we can treat the first
fstatat as atomic. Warn “file changed” when the file’s size,
mtime, user ID, group ID, or mode changes, instead of when the
file’s size or ctime changes. Also, when such a change happens,
do not change exit status if --ignore-failed-read. Finally, don’t
attempt to change atime back if it didn’t change.
* src/create.c (dump_file0): For clarity, change diagnostic
wording from "file is the archive; not dumped" to "archive cannot
contain itself; not dumped". All test cases and documentation changed.
* doc/Makefile.am (GENDOCS): Use the version from the tar repository.
(manual): Set the DISTRIN rendition.
(manual-rebuild): New goal.
* doc/README.manual: New file. Instructions for maintainers on how to
update web documentation.
* doc/gendocs.sh: A version from gnulib fixed as per
https://lists.gnu.org/archive/html/bug-gnulib/2021-03/msg00002.html.
* doc/gendocs_template: Updated version from gnulib.
* doc/intern.texi: Fix the use of UNREVISED.
* doc/tar.texi: Fix the use of GNUTAR.
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.
* doc/tar.texi: Document changes.
* src/common.h (tar_args): Move from tar.c
(TAR_ARGS_INITIALIZER): New macro.
* src/names.c: Declare option group identifiers as an enum.
(names_parse_opt): Special handling for ARGP_KEY_ERROR.
(names_argp): Remove static qualifier.
(names_argp_children): Remove.
* src/tar.c: Declare option group identifiers as an enum.
(parse_opt): Special handling for ARGP_KEY_INIT.
(argp_children): New static variable.
(args): Remove static variable.
(more_options): Allow only options from names_argp.
(parse_default_options): Take a pointer to struct tar_args as argument.
Replace the loc member during the call to argp_parse and restore it
afterwards.
(decode_options): Use automatic variable for args.
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
