[Lzip-bug] Clzip 1.10 released

[Antonio Diaz Diaz]

I am pleased to announce the release of clzip 1.10.

Clzip is a C language version of lzip, fully compatible with lzip-1.4 or 
newer. As clzip is written in C, it may be easier to integrate in 
applications like package managers, embedded devices, or systems lacking 
a C++ compiler.

Lzip is a lossless data compressor with a user interface similar to the 
one of gzip or bzip2. Lzip can compress about as fast as gzip (lzip -0), 
or compress most files more than bzip2 (lzip -9). Decompression speed is 
intermediate between gzip and bzip2. Lzip is better than gzip and bzip2 
from a data recovery perspective.

The lzip file format is designed for data sharing and long-term 
archiving, taking into account both data integrity and decoder availability.

This release is also GPG signed. You can download the signature by 
appending '.sig' to the URL. If the 'gpg --verify' command fails because 
you don't have the required public key, then run this command to import it:

  gpg --keyserver keys.gnupg.net --recv-keys 8FE99503132D7742

Key fingerprint = 1D41 C14B 272A 2219 A739  FA4F 8FE9 9503 132D 7742


Changes in version 1.10:

  * The option '--loose-trailing', has been added.

  * The test used by clzip to discriminate trailing data from a corrupt 
header in multimember or concatenated files has been improved to a 
Hamming distance (HD) of 3, and the 3 bit flips must happen in different 
magic bytes for the test to fail. As a consequence some kinds of files 
no longer can be appended to a lzip file as trailing data unless the 
'--loose-trailing' option is used when decompressing.
Lziprecover can be used to remove conflicting trailing data from a file.

  * The contents of a corrupt or truncated header found in a 
multimember file are now shown, after the error message, in the same 
format as trailing data.

  * Option '-S, --volume-size' now keeps input files unchanged.

  * When creating multimember files or splitting the output in volumes, 
the dictionary size is now adjusted for each member individually.

  * The 'bits/byte' ratio has been replaced with the inverse 
compression ratio in the output.

  * The progress of decompression is now shown at verbosity level 2 
(-vv) or higher.

  * Progress of (de)compression is only shown if stderr is a terminal.

  * A final diagnostic is now shown at verbosity level 1 (-v) or higher 
if any file fails the test when testing multiple files.

  * A second '.lz' extension is no longer added to the argument of '-o' 
if it already ends in '.lz' or '.tlz'.

  * In case of (de)compressed size mismatch, the stored size is now 
also shown in hexadecimal to ease visual comparison.

  * The dictionary size is now shown at verbosity level 4 (-vvvv) when 
decompressing or testing.

  * The new chapter "Meaning of clzip's output" has been added to the 
manual.
