I am pleased to announce the release of tarlz 0.25.

Tarlz is a massively parallel (multi-threaded) combined implementation of the tar archiver and the lzip compressor. Tarlz uses the compression library lzlib.

Tarlz creates tar archives using a simplified and safer variant of the POSIX pax format compressed in lzip format, keeping the alignment between tar members and lzip members. The resulting multimember tar.lz archive is backward compatible with standard tar tools like GNU tar, which treat it like any other tar.lz archive. Tarlz can append files to the end of such compressed archives.

Keeping the alignment between tar members and lzip members has two advantages. It adds an indexed lzip layer on top of the tar archive, making it possible to decode the archive safely in parallel. It also minimizes the amount of data lost in case of corruption. Compressing a tar archive with plzip may even double the amount of files lost for each lzip member damaged because it does not keep the members aligned.

Changes in version 0.25:

* The new option '--ignore-metadata', which makes '-d, --diff' ignore differences in file permissions, owner and group IDs, and modification time, has been added.

  * '#include <sys/types.h>' for major, minor, and makedev on BSD systems.

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

* The option '-o, --output' now creates missing intermediate directories when compressing to a file.

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


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

Antonio Diaz, tarlz author and maintainer.
