I am pleased to announce the release of xlunzip 0.9.
Xlunzip is a test tool for the lzip decompression code of my lzip patch for
linux. Xlunzip is similar to lunzip, but it uses the lzip_decompress linux
module as a backend. Xlunzip tests the module for stream, buffer-to-buffer,
and mixed decompression modes, including in-place decompression (using the
same buffer for input and output). You can use xlunzip to check that the
module produces correct results when decompressing single member files,
multimember files, or the concatenation of two or more compressed files.
Xlunzip can be used with unzcrash to test the robustness of the module to
the decompression of corrupted data.
The distributed index feature of the lzip format allows xlunzip to
decompress concatenated files in place. This can't be guaranteed to work
with formats like gzip or bzip2 because they can't detect whether a high
compression ratio in the first members of the multimember data is being
masked by a low compression ratio in the last members.
The xlunzip tarball contains a copy of the lzip_decompress module and can be
compiled and tested without downloading or applying the patch to the kernel.
The homepage is at http://www.nongnu.org/lzip/xlunzip.html
The sources can be downloaded from

xlunzip-0.9.tar.lz
The lzip patch for linux can be found at
http://download.savannah.gnu.org/releases/lzip/kernel/
Changes in version 0.9:
* xlunzip now exits with error status 2 if any empty member is found in a
multimember file.
* xlunzip now exits with error status 2 if the first byte of the LZMA
stream is not 0.
Please send bug reports and suggestions to lzip-bug@nongnu.org
Regards,
Antonio Diaz, xlunzip author and maintainer.

If you know someone who is using gzip, bzip2, or xz, please tell him/her
about the advantages of switching to lzip. See
