* Fix the --verify option, which broke in version 1.24.
* Fix storing long sparse file names in PAX archives.
* Fix correctness of --atime-preserve=replace.
* Work around POSIX incompatibilities on FreeBSD, NetBSD and Tru64.
* Fix bug with --one-file-system --listed-incremental.
NetBSD-current and Solaris 10 (tested by tez@), the other one was
adding a --no-unlink-first option that was added because NetBSD's
version of tar had made --unlink-first default. Since this default
was changed quite some time ago and the option never was in upstream,
remove it.
Bump PKGREVISION.
version 1.25 - Sergey Poznyakoff, 2010-11-07
* Fix extraction of empty directories with the -C option in effect.
* Fix extraction of device nodes.
* Make sure name matching occurs before eventual name transformation.
Tar 1.24 changed the ordering of name matching and name transformation
so that the former saw already transformed file names. This made it
impossible to match file names in certain cases. It is fixed now.
* Fix the behavior of tar -x --overwrite on hosts lacking O_NOFOLLOW.
* Improve the testsuite.
* Alternative decompression programs.
If extraction from a compressed archive fails because the corresponding
compression program is not installed and the following two conditions
are met, tar retries extraction using an alternative decompressor:
1. Another compression program supported by tar is able to handle this
compression format.
2. The compression program was not explicitly requested in the command
line by the use of such options as -z, -j, etc.
For example, if `compress' is not available, tar will try `gzip'.
version 1.24 - Sergey Poznyakoff, 2010-10-24
* The --full-time option.
New command line option `--full-time' instructs tar to output file
time stamps to the full resolution.
* Bugfixes.
** More reliable directory traversal when creating archives
Tar now checks for inconsistencies caused when a file system is
modified while tar is creating an archive. In the new approach, tar
maintains a cache of file descriptors to directories, so it uses more
file descriptors than before, but it adjusts to system limits on
the number of file descriptors. Tar also takes more care when
a file system is modified while tar is extracting from an archive.
The new checks are implemented via the openat and related calls
standardized by POSIX.1-2008. On an older system where these calls do
not exist or do not return useful results, tar emulates the calls at
some cost in efficiency and reliability.
** Symbolic link attributes
When extracting symbolic links, tar now restores attributes such as
last-modified time and link permissions, if the operating system
supports this. For example, recent versions of the Linux kernel
support setting times on symlinks, and some BSD kernels also support
symlink permissions.
** --dereference consistency
The --dereference (-h) option now applies to files that are copied
into or out of archives, independently of other options. For example,
if F is a symbolic link and archive.tar contains a regular-file member
also named F, "tar --overwrite -x -f archive.tar F" now overwrites F
itself, rather than the file that F points to. (To overwrite the file
that F points to, add the --dereference (-h) option.) Formerly,
--dereference was intended to apply only when using the -c option, but
the implementation was not consistent.
Also, the --dereference option no longer affects accesses to other
files, such as archives and time stamp files. Symbolic links to these
files are always followed. Previously, the links were usually but not
always followed.
** Spurious error diagnostics on broken pipe.
When receiving SIGPIPE, tar would exit with error status and
"write error" diagnostics. In particular, this occurred if
invoked as in the example below:
tar tf archive.tar | head -n 1
** --remove-files
`Tar --remove-files' failed to remove a directory which contained
symlinks to another files within that directory.
** --test-label behavior
In case of a mismatch, `tar --test-label LABEL' exits with code 1,
not 2 as it did in previous versions.
The `--verbose' option used with `--test-label' provides additional
diagnostics.
Several volume labels may be specified in a command line, e.g.:
tar --test-label -f archive 'My volume' 'New volume' 'Test volume'
In this case, tar exits with code 0 if any one of the arguments
matches the actual volume label.
** --label used with --update
The `--label' option can be used with `--update' to prevent accidental
update of an archive:
tar -rf archive --label 'My volume' .
This did not work in previous versions, in spite of what the docs said.
** --record-size and --tape-length (-L) options
Usual size suffixes are allowed for these options. For example,
-L10k stands for a 10 kilobyte tape length.
** Fix dead loop on extracting existing symlinks with the -k option.
Also:
# Improved record size autodetection
# Use of lseek on seekable archives
# New command line option --warning
# New command line option --level
# Improved behavior if some files were removed during incremental dumps
# Modification times of PAX extended headers
# Time references in the --pax-option argument
# Augmented environment of the --to-command script
# Bugfixes:
* Fix handling of hard link targets by -c --transform
* Fix hard links recognition with -c --remove-files
* Fix restoring files from backup (debian bug #508199)
* Correctly restore modes and permissions on existing directories
* The --remove-files option removes files only if they were succesfully stored in the archive
* Fix storing and listing of the volume labels in POSIX format
* Improve algorithm for splitting long file names (ustar format)
version 1.22 - Sergey Poznyakoff, 2009-03-05
* Support for xz compression
Tar uses xz for compression if one of the following conditions is met:
1. The option --xz or -J (see below) is used.
2. The xz binary is set as compressor using --use-compress-program option.
3. The file name of the archive being created ends in `.xz' and
auto-compress option (-a) is used.
Xz is used for decompression if one of the following conditions is met:
1. The option --xz or -J is used.
2. The xz binary is set as compressor using --use-compress-program option.
3. The file is recognized as xz compressed stream data.
* Short option -J reassigned as a short equivalent of --xz
* New option -I
The -I option is assigned as a short equivalent for
--use-compress-program.
* The --no-recursive option works in incremental mode.
version 1.21 - Sergey Poznyakoff, 2008-12-27
* New short option -J
A shortcut for --lzma.
* New option --lzop
* New option --no-auto-compress
Cancels the effect of previous --auto-compress (-a) option.
* New option --no-null
Cancels the effect of previous --null option.
* Compressed format recognition
If tar is unable to determine archive compression format, it falls
back to using archive suffix to determine it.
* VCS support.
Using --exclude-vcs handles also files used internally by Bazaar,
Mercurial and Darcs.
* Transformation scope flags
Name transformation expressions understand additional flags that
control type of archive members affected by them. The flags are:
- r
Apply transformation to regular archive members.
- s
Apply transformation to symbolic link targets.
- h
Apply transformation to hard link targets.
Corresponding upper-case letters negate the meaning, so that
`H' means ``do not apply transformation to hard link targets.''
The scope flags are listed in the third part of an `s' expression,
e.g.:
tar --transform 's|^|/usr/local/|S'
Default is `rsh', which means that transformations are applied to
both regular archive members and to the targets of symbolic and hard
links. If several transform expressions are used, the default flags
can be changed using `flags=' statement before the expressions, e.g.:
tar --transform 'flags=S;s|^|/usr/local/|S'
* Bugfixes
** The --null option disabled handling of tar options in list files. This
is fixed.
** Fixed record size autodetection. If detected record size differs from
the expected value (either default, or set on the command line), tar
always prints a warning if verbosity level is set to 1 or greater,
i.e. if either -t or -v option is given.
gtar cowardly refuses to build if time_t doesn't fit in "long int",
as happens to be the case now on 32-bit NetBSD hosts.
Supress the error and turn it into a warning instead.
"make test" still OK
PKGLOCALEDIR and which install their locale files directly under
${PREFIX}/${PKGLOCALEDIR} and sort the PLIST file entries. From now
on, pkgsrc/mk/plist/plist-locale.awk will automatically handle
transforming the PLIST to refer to the correct locale directory.
developer is officially maintaining the package.
The rationale for changing this from "tech-pkg" to "pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list). Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.
changes:
- enable installation of grmt
changes in gtar:
version 1.15.1 - Sergey Poznyakoff, 2004-12-21
This version fixes a bug introduced in 1.15 which caused
tar to refuse to extract files from standard input.
version 1.15 - Sergey Poznyakoff, 2004-12-20
* Compressed archives are recognised automatically, it is no longer
necessary to specify -Z, -z, or -j options to read them. Thus, you can
now run `tar tf archive.tar.gz'.
* When restoring incremental dumps, --one-file-system option
prevents directory hierarchies residing on different devices
from being purged.
With the previous versions of tar it was dangerous to create
incremental dumps with --one-file-system option, since they
would recursively remove mount points when restoring from the
back up. This change fixes the bug.
* Renamed --strip-path to --strip-components for consistency with
the GNU convention.
* Skipping archive members is sped up if the archive media supports
seeks.
* Restore script starts restoring only if it is given --all (-a) option,
or some patterns. This is to prevent accidental restores.
* `tar --verify' prints a warning if during archive creation some of
the file names had their prefixes stripped off.
* New option --exclude-caches instructs tar to exclude cache directories
automatically on archive creation. Cache directories are those
containing a standardized tag file, as specified at:
http://www.brynosaurus.com/cachedir/spec.html
* New configure option --with-rmt allows to specify full path name to
the `rmt' utility. This supercedes DEFAULT_RMT_COMMAND variable
introduced in version 1.14
* New configure variable DEFAULT_RMT_DIR allows to specify the directory
where to install `rmt' utility. This is necessary since modifying
--libexecdir as was suggested for version 1.14 produced a side effect: it
also modified installation prefix for backup scripts (if
--enable-backup-scripts was given).
* Bugfixes:
** Fixed flow in recognizing files to be included in incremental dumps.
** Correctly recognize sparse archive members when used with -T option.
** GNU multivolume headers cannot store filenames longer than 100 characters.
Do not allow multivolume archives to begin with such filenames.
** If a member with link count > 2 was stored in the archive twice,
previous versions of tar were not able to extract it, since they
were trying to link the file to itself, which always failed and
lead to removing the already extracted copy. Preserve the first
extracted copy in such cases.
** Restore script was passing improper argument to tar --listed option (which
didn't affect the functionality, but was logically incorrect).
** Fixed verification of created archives.
** Fixed unquoting of file names containing backslash escapes (previous
versions failed to recognize \a and \v).
** When attempting to delete a non-existing member from the archive, previous
versions of tar used to overwrite last archive block with zeroes.
