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 is 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.
