Description 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 verify 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. Note that the in-place decompression of concatenated files can't be guaranteed to work because an arbitrarily low compression ratio of the last part of the data can be achieved by appending enough empty compressed members to a file, masking a high compression ratio at the beginning of the data. 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. My lzip patch for linux can be found at http://download.savannah.gnu.org/releases/lzip/kernel/ Lzip related components in the kernel ===================================== The lzip_decompress module in lib/lzip_decompress.c provides a versatile lzip decompression function able to do buffer to buffer decompression or stream decompression with fill and flush callback functions. The usage of the function is documented in include/linux/lzip.h. For decompressing the kernel image, initramfs, and initrd, there is a wrapper function in lib/decompress_lunzip.c providing the same common interface as the other decompress_*.c files, which is defined in include/linux/decompress/generic.h.
