* scripts/backup.in: Check exit code of MT_BEGIN
* scripts/backup.sh.in (backup_host): Return meaningful code
in case of remote execution. See the comment, though.
* src/common.h (name_more_files): New proto.
(files_from_option): Remove.
* src/names.c (name_more_files): New file.
(names_options): Fix declaration of the
add-file option.
(names_parse_opt): Handle --add-file.
* 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.
(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 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.
Be careful to define HAVE_XATTRS when not all needed xattr-related
functions are properly defined either in libc or libattr.
Reported independently by Denis Excoffier and Dominyk Tille.
* acinclude.m4 (TAR_HEADERS_ATTR_XATTR_H): Check for each xattr
function separately. Don't AC_CHECK_LIB (LIBS is filled by
AC_SEARCH_LIBS when necessary).
* src/Makefile.am: The LDADD -lattr was redundant.
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.
Patch submitted by Jeremy Bobbio and
Daniel Kahn Gillmor <dkg@fifthhorseman.net>
* doc/tar.1: Document --clamp-mtime
* doc/tar.texi: Likewise.
* src/common.h (set_mtime_option_mode): New enum
(set_mtime_option): Change type to enum set_mtime_option_mode.
(NEWER_OPTION_INITIALIZED): Rename to NEWER_OPTION_INITIALIZED.
* src/create.c (start_header): Set mtime depending on set_mtime_option.
* src/tar.c (options,parse_opt): New option --clamp-mtime
(decode_options): Initialize mtime_option
* tests/time02.at: New testcase.
* tests/Makefile.am: Add new testcase
* tests/testsuite.at: Likewise.
* tests/sparse06.at: Don't use timeout: depending on the filesystem
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.
* tests/numeric.at: Avoid using awk -v: some older awks don't support
that option. Also fix environment variable usage.
* tests/onetop05.at: Skip test if unable to set initial directory
mode bits.
* tests/sparse06.at: Use --quiet option.
* src/buffer.c (flush_archive): If previous reading attempt resulted
in short read, correctly use the remaining record space.
(backspace_output): Fix position calculation (still has to be
improved).
* tests/append05.at: New test case.
* tests/Makefile.am: Add new test.
* tests/testsuite.at: Likewise.
Patch provided by Charles McGarvey and Flavio Poletti.
* src/transform.c (parse_transform_expr): Allow escaped delimiters
in transform expressions.
* tests/xform02.at: New test case.
* tests/Makefile.am: Add xform02.at
* tests/testsuite.at: Include xform02.at
* THANKS: Update.
* doc/tar.texi: Document position-sensitive options in a
separate subsection.
* src/names.c (names_argp,names_argp_children): Explicitly initialize
all members.
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.
(name_add_name): Change signature.
(name_add_dir, name_add_file): Remove prototypes.
* src/names.c (name_add_option, name_add_dir)
(name_add_file): Static functions.

(names_argp_children): New variable.
(NELT_NAME, NELT_CHDIR)
(NELT_FILE, NELT_NOOP): Redefine as enum nelt_type.
(NELT_FMASK): Remove.
(NELT_OPTION): New constant.
(name_elt) <type>: Change type.
<v.opt>: New member.
(name_elt_alloc_matflags): Remove.
(name_add_name): Take one argument.
(name_add_option): New static function.
(name_add_file): Take one argument.
(read_next_name): Use filename_terminator and
verbatim_files_from_option to initialize file.term and file.verbatim.
* src/tar.c: Move handling of filename-selection options to names.c
* tests/T-dir00.at: Fix typo.
* tests/T-recurse.at: Remove expected failure.
* tests/recurs02.at: Also test --list mode.
* tests/T-recurse.at: New test case. Test that -T option works
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.
