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.
* important changes in version 1.72 18/11/2010
- Apply patch from Grant McLean to update docs for
ptargrep
* important changes in version 1.70 15/11/2010
- Add ptargrep utility courtesy of Grant McLean
* The memory usage limit is now disabled by default.
* Added support for XZ_DEFAULTS environment variable.
* The compression settings associated with the preset levels
-0 ... -9 have been changed. --extreme was changed a little too.
* If a preset level (-0 ... -9) is specified after a custom filter
chain options have been used (e.g. --lzma2), the custom filter
chain will be forgotten. Earlier the preset options were
completely ignored after custom filter chain options had been seen.
* xz will create sparse files when decompressing if the uncompressed
data contains long sequences of binary zeros.
* Support for "xz --list" was added. Combine with --verbose or
--verbose --verbose (-vv) for detailed output.
* I had hoped that liblzma API would have been stable after
4.999.9beta, but there have been a couple of changes in the
advanced features, which don't affect most applications:
- Index handling code was revised. If you were using the old
API, you will get a compiler error (so it's easy to notice).
- A subtle but important change was made to the Block handling
API. lzma_block.version has to be initialized even for
lzma_block_header_decode(). Code that doesn't do it will work
for now, but might break in the future, which makes this API
change easy to miss.
* The major soname has been bumped to 5.0.0. liblzma API and ABI
are now stable, so the need to recompile programs linking against
liblzma shouldn't arise soon.
Libarchive is a programming library that can create and read several
different streaming archive formats, including most popular tar
variants, several cpio formats, and both BSD and GNU ar variants.
* Use lang/ruby/gem.mk.
= Version 0.9.4
Changed ZipOutputStream.put_next_entry signature (API CHANGE!). Now
allows comment, extra field and compression method to be specified.
= Version 0.9.3
Fixed: Added ZipEntry::name_encoding which retrieves the character
encoding of the name and comment of the entry. Also added convenience
methods ZipEntry::name_in(enc) and ZipEntry::comment_in(enc) for
getting zip entry names and comments in a specified character
encoding.
= Version 0.9.2
Fixed: Renaming an entry failed if the entry's new name was a
different length than its old name. (Diego Barros)
Upstream changes:
* important changes in version 1.68 17/08/2010
- Apply a patch from Colin Newell that checks whether long files can be created or
not in 02_methods.t. Hopefully resolves RT #57312 and RT #56163
to trigger/signal a rebuild for the transition 5.10.1 -> 5.12.1.
The list of packages is computed by finding all packages which end
up having either of PERL5_USE_PACKLIST, BUILDLINK_API_DEPENDS.perl,
or PERL5_PACKLIST defined in their make setup (tested via
"make show-vars VARNAMES=..."), minus the packages updated after
the perl package update.
sno@ was right after all, obache@ kindly asked and he@ led the
way. Thanks!
pkgsrc changes:
- mark package included in Perl5 CORE

Adds option -C to allow archives created with ptar to be uploaded to
PAUSE in case of Windows or world +w permissions on unix.
* important changes in version 1.64 09/07/2010
- Removed the PERL_CORE specific chdir from all the tests
- Apply a patch from David Muir Sharnoff RT #58916,
"skip files via a callback and limit memory use when skipping files"
- Apply a patch from Daphne Pfister RT #59150
"Assumes all references filename are IO::Handle's instead of trying
to stringify."
* important changes in version 1.62 28/06/2010
- Apply part of patch from
https://bugzilla.redhat.com/attachment.cgi?id=426194
reported by Martin Cermak in RT #58636 relating to a Redhat ticket
https://bugzilla.redhat.com/show_bug.cgi?id=606813
* important changes in version 1.60 23/04/2010
- Apply patch from Darrell K. [RT #54850] that makes write() and
create_archive() close only handles they opened.
When you pass a filehandle to Archive::Tar::write() or create_archive(),
it closes the filehandle after writing to it. I think it makes more
sense not to close a handle that A::T didn't open, since the application
may need to write additional data to it. (Consider sockets, package
files containing encapsulated tar archives, etc.)
Example:
$ perl -e 'use Archive::Tar; open(PKG, ">mypkg") or die "open: $!"; my
$tar = Archive::Tar->new; $tar->add_data("foo.txt","hello");
$tar->write(\*PKG); print PKG "more data" or die "print: $!";'
print: Bad file descriptor at -e line 1.
