Log message:
Update to 1.31

Changelog:
version 1.31 - Sergey Poznyakoff, 2019-01-02

* Fix heap-buffer-overrun with --one-top-level.
Bug introduced with the addition of that option in 1.28.

* Support for zstd compression

New option '--zstd' instructs tar to use zstd as compression program.
When listing, extractng and comparing, zstd compressed archives are
recognized automatically.
When '-a' option is in effect, zstd compression is selected if the
destination archive name ends in '.zst' or '.tzst'.

* The -K option interacts properly with member names given in the command line

Names of members to extract can be specified along with the "-K NAME"
option. In this case, tar will extract NAME and those of named members
that appear in the archive after it, which is consistent with the
semantics of the option.

Previous versions of tar extracted NAME, those of named members that
appeared before it, and everything after it.

* Fix CVE-2018-20482

When creating archives with the --sparse option, previous versions of
tar would loop endlessly if a sparse file had been truncated while
being archived.

gtar: update to 1.30

version 1.30 - Sergey Poznyakoff, 2017-12-17

* Member names containing '..' components are now skipped when extracting.

This fixes tar's behavior to match its documentation, and is a bit
safer when extracting untrusted archives over old files (an unsafe
practice that the tar manual has long recommended against).

* Report erroneous use of position-sensitive options.

During archive creation or update, tar keeps track of positional
options (see the manual, subsection 3.4.4 "Position-Sensitive
Options"), and reports those that had no effect.  For example, when
invoked as

   tar -cf a.tar . --exclude '*.o'

tar will create the archive, but will exit with status 2, having
issued the following error message

   tar: The following options were used after non-optional
   arguments in archive create or update mode.  These options are
   positional and affect only arguments that follow them.  Please,
   rearrange them properly.
   tar: --exclude '*.o' has no effect
   tar: Exiting with failure status due to previous errors

* --numeric-owner now affects private headers too.

This helps the output of 'tar' to be more deterministic.

* Fixed the --delay-directory-restore option

In some cases tar would restore the directory permissions too early,
causing subsequent link extractions in that directory to fail.

* The --warnings=failed-read option

This new warning control option suppresses warning messages about
unreadable files and directories. It has effect only if used together
with the --ignore-failed-read option.

* The --warnings=none option now suppresses all warnings

This includes warnings about unreadable files produced when
--ignore-failed-read is in effect. To output these, use
--warnings=none --warnings=no-failed-read.

* Fix reporting of hardlink mismatches during compare

Tar reported incorrect target file name in the 'Not linked to'
diagnostic message.

Log message:
Sort PLIST files.

Unsorted entries in PLIST files have generated a pkglint warning for at
least 12 years. Somewhat more recently, pkglint has learned to sort
PLIST files automatically. Since pkglint 5.4.23, the sorting is only
done in obvious, simple cases. These have been applied by running:

  pkglint -Cnone,PLIST -Wnone,plist-sort -r -F

------------------------------------
version 1.29 - Sergey Poznyakoff, 2016-05-16

* New options: --verbatim-files-from, --no-verbatim-files-from

The --verbatim-files-from option instructs tar to treat each line read
from a file list as a file name, even if it starts with a dash.

File lists are supplied with the --files-from (-T) option.  By
default, each line read from a file list is first stripped off the
leading and trailing whitespace and, if the result begins with a dash,
it is treated as tar command line option.

Use the --verbatim-files-from option to disable this special handling.
This facilitates the use of tar with file lists created automatically
(e.g. by find(1) command).

This option affects all --files-from options that occur after it in
the command line.  Its effect is reverted by the
--no-verbatim-files-from option.

* --null option reads file names verbatim

The --null option implies --verbatim-files-from.  I.e. each line
read from null-delimited file lists is treated as a file name.

This restores the documented behavior, which was broken in version
1.27.

* New options: --owner-map=FILE and --group-map=FILE

These two options provide fine-grained control over what user/group
names (or IDs) should be mapped when adding files to archive.

For both options, FILE is a plain text file with user or group
mappings.  Empty lines are ignored.  Comments are introduced with
# sign (unless quoted) and extend to the end of the corresponding
line.  Each non-empty line defines translation for a single UID (GID).
It must consist of two fields, delimited by any amount of whitespace:

     OLDNAME NEWNAME[:NEWID]

OLDNAME is either a valid user (group) name or a ID prefixed with +.  Unless
NEWID is supplied, NEWNAME must also be either a valid name or a
+ID.  Otherwise, both NEWNAME and NEWID need not be listed in the
system user database.

* New option --clamp-mtime

The new --clamp-mtime option changes 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
reference (and thus reproducible) timestamps for the latter is good
enough.

See <https://wiki.debian.org/ReproducibleBuilds> for more information.

* Deprecated --preserve option removed

* Sparse file detection

Tar now uses SEEK_DATA/SEEK_HOLE on systems that support it.  This
allows for considerable speed-up in sparse-file detection.

New option --hole-detection is provided, that allows the user to
select the algorithm used for hole detection.  Available arguments
are:

  --hole-detection=seek
     Use lseek(2) SEEK_DATA and SEEK_HOLE "whence" parameters.

  --hole-detection=raw
     Scan entire file before storing it to determine where holes
     are located.

The default is to use "seek" whenever possible, and fall back to
"raw" otherwise.

Log message:
Force the use of the gnulib version of wctype.h, bundled with gtar, when building
on AIX. This is a workaround for an issue where though the wctype.h included on
system was found, wctype_t & wctrans_t were deemed unsuitable, causing the build
to fail due to previous declaration with confliciting types.
