- Update to new upstream release 1.8.1.2
* Most visible new feature is support for dictionary compression
* Support is now more formally added on the API side within
lib/lz4frame_static.h. It's early days, and this new API is
tagged "experimental" for the time being.
* Support is also added in the command line utility lz4, using
the new command -D. The behavior of this command is identical
to zstd, should you be already familiar.
* lz4 doesn't specify how to build a dictionary. All it says is
that it can be any file up to 64 KB.
* This approach is compatible with zstd dictionary builder, which
can be instructed to create a 64 KB dictionary.
* Improved performance at ultra settings (levels 10+).
* These levels receive a new code, called optimal parser,
available in lib/lz4_opt.h.
* New parser uses less memory (from 384KB to 256KB), performs
faster, compresses a little bit better (not much, as it was
already close to theoretical limit), and resists pathological
patterns which could destroy performance.
* New parser is directly compatible with lower compression levels,
which brings additional benefits:
+ Compatibility with LZ4_*_destSize() variant, which reverses
the logic by trying to fit as much data as possible into a
predefined limited size buffer.
+ Compatibility with Dictionary compression, as it uses the
same tables as regular HC mode
* In the future, this compatibility will also allow dynamic change
of compression level.
* Small set of bug fixes and improvements:
+ perf : faster and stronger ultra modes (levels 10+)
+ perf : slightly faster compression and decompression speed
+ perf : fix bad degenerative case
+ fix : decompression failed when using a combination of
extDict + low memory address
+ cli : support for dictionary compression (-D)
+ cli : fix : lz4 -d --rm preserves timestamp
+ cli : fix : do not modify /dev/null permission as root
+ api : _destSize() variant supported for all compression
levels
+ build : make and make test compatible with parallel build -jX
+ build : can control LZ4LIB_VISIBILITY macro
+ install: fix man page directory
- partial cleanup with spec-cleaner
- rebase lz4-use-shlib.diff
- drop lz4-use-shlib.diff, breaks build
- misc spec cleanups
- remove Makefile fix
- build and install separately
- New URL

LZ4 is a lossless data compression algorithm that is focused on
|
||
compression and decompression speed. It belongs to the LZ77
|
||
(Lempel–Ziv) family of byte-oriented compression schemes. It is a
|
||
LZP2 fork and provides better compression ratio for text files.
|
||
|
||
This subpackage provides a GPL command-line utility to make use of
|
||
the LZ4 algorithm.
