When compressing on a 32 bit system, plzip now tries to limit the memory
|
|
|
|
|
use to under 2.22 GiB (4 worker threads at level -9) by reducing the
|
|
|
|
|
number of threads below the system's default.

|
|
|
The test used by plzip to discriminate trailing data from a corrupt
|
|
|
|
|
header in multimember regular (seekable) 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.
|
|
|
|
|
Lzlib 1.10 or newer is required for this test to work on non-seekable
|
|
|
|
|
files.
|
|
|
|
|
Lziprecover can be used to remove conflicting trailing data from a file.
|
|
|
|
|
|
|
|
|
|
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 second '.lz' extension is no longer added to the argument of '-o' if
|
|
|
|
|
it already ends in '.lz' or '.tlz'.
|
|
|
|
|
|
|
|
|
|
The dictionary size is now shown at verbosity level 4 (-vvvv) when
|
|
|
|
|
decompressing or testing.
|
|
|
|
|
|
|
|
|
|
The new chapter "Meaning of plzip's output", and a block diagram of
|
|
|
|
|
plzip have been added to the manual.
