[Lzip-bug] Xlunzip 0.8 released

[Antonio Diaz Diaz]

I am pleased to announce the release of xlunzip 0.8.

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.

Changes in version 0.8:

  * File diagnostics have been reformatted as 'PROGRAM: FILE: MESSAGE'.

  * In case of error in a numerical argument to a command line option, 
lunzip now shows the name of the option and the range of valid values.

  * Diagnostics caused by invalid arguments to command-line options now 
show the argument and the name of the option.

  * The option '-o, --output' now preserves dates, permissions, and 
ownership of the file, when decompressing exactly one file.

  * The variable MAKEINFO has been added to configure and Makefile.in.

  * It has been documented in INSTALL that when choosing a C standard, the 
POSIX features need to be enabled explicitly:
  ./configure CFLAGS+='--std=c99 -D_XOPEN_SOURCE=500'


Please send bug reports and suggestions to lzip-bug@nongnu.org
