Commit e89c7a45eb broke deletion from archives. The reported number
of bytes read is rounded to the nearest record anyway, revert the
commit and document the fact.
Reported by Ed Santiago. See
https://bugzilla.redhat.com/show_bug.cgi?id=2230127
* doc/tar.texi: Document the fact that --totals rounds up the
number of bytes reads to the nearest record.
* src/buffer.c: Revert changes.
* tests/delete06.at: Fix expected status code and stderr.
* doc/tar.texi (Reproducibility): Improve index.
Improve and add comments to recipe. In the recipe,
don’t worry about file names beginning with ‘-’ for simplicity;
don’t use touch -c as it exits with status 0 even when it
does not work; and set directory timestamps too.
* doc/tar.1: Add missing dots, use plural when necessary,
tweak a wording. Remove an incorrect observation, three times.
Add some missing articles, correct some formatting,
and expand the opaque descriptions of two options.
* doc/tar.texi: Drop a stray `cd` command from an example.
Correct two cross references, correct the paragraph
about the manpage, and unbreak a URL.
* src/names.c: Correct and shorten an error message: "non-optional"
means "mandatory", but "non-option" is what was meant. And the
phrase "in archive create or update mode" was both unneeded and
incomplete.
* tests/positional01.at: Change expected error text.
* tests/positional02.at: Likewise.
* tests/positional03.at: Likewise.
* doc/tar.texi (Extended File Attributes): The default extraction
pattern consists of just 'user.*' namespace only. While on it, try
to explain the reasons for this default behavior.
* doc/tar.1: Add needed option -f after operation -A, sort operation -t
alphabetically, add --file after --concatenate, consistently use long
option --file in the GNU-style section, and delete duplicate --update.
* doc/tar.texi: Add small missing word, and lowercase a letter.
(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.
