I am pleased to announce the release of xlunzip 0.10.

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 lzip patch for linux can be found at http://download.savannah.gnu.org/releases/lzip/kernel/

Changes in version 0.10:

* '-dvv' and '-tvv' now print (de)compressed sizes instead of compression ratio. (Sizes are more informative than compression ratio).

* Large numbers in option arguments are now accepted with underscore separators (--insize=123_456_789).

  * Large numbers are now printed with underscore separators (123_456_789).

  * 'EXIT STATUS' now has its own section in the man page.
