Sun Sep 17 09:08:22 UTC 2023 - Dirk Müller <dmueller@suse.com>
|
||||||
|
|
||||||
|
- update to 1.19:
|
||||||
|
* Added new functions `libdeflate_alloc_compressor_ex()` and
|
||||||
|
`libdeflate_alloc_decompressor_ex()`. These functions allow
|
||||||
|
specifying a custom memory allocator on a per-compressor basis.
|
||||||
|
* libdeflate now always generates Huffman codes with at least 2
|
||||||
|
codewords. This fixes a compatibility issue where Windows
|
||||||
|
Explorer's ZIP unpacker could not decompress DEFLATE streams
|
||||||
|
created by libdeflate. libdeflate's behavior was
|
||||||
|
* allowed by the DEFLATE RFC, but not all software was okay
|
||||||
|
with it. In rare cases, compression ratios can be slightly
|
||||||
|
reduced by this change.
|
||||||
|
* Disabled the use of some compiler intrinsics on MSVC versions
|
||||||
|
where they don't work correctly.
|
||||||
|
* libdeflate can now compress up to the exact size of the
|
||||||
|
output buffer.
|
||||||
|
* Slightly improved compression performance at levels 1-9.
|
||||||
|
* Improved the compression ratio of very short inputs.

||||||

Thu Apr 27 22:43:07 UTC 2023 - Dirk Müller <dmueller@suse.com>
|
||||||
|
|
||||||
|
- update to 1.18:
|
||||||
|
* Fixed a bug where the build type didn't default to "Release"
|
||||||
|
when using CMake 3.10 or earlier.
|
||||||
|
* Fixed a bug where some optimized code wasn't used when
|
||||||
|
building with Clang 15 or later (x86), or with Clang 16
|
||||||
|
or later (aarch64).
|
||||||
|
* Fixed build errors with some architecture and compiler
|
||||||
|
combos:
|
||||||
|
* aarch64 with Clang 16
|
||||||
|
* armv6kz or armv7e-m with gcc
|
||||||
|
* armhf with gcc (on Debian only)

|
||||||
|
|
||||||
|
- update to 1.17:
|
||||||
|
* Improved the compression ratio at levels 10-12 slightly, mainly
|
||||||
|
levels 11-12. Some inputs (such as certain PNG files) see much
|
||||||
|
improved compression ratios. As a trade-off, compressing at
|
||||||
|
levels 11-12 is now about 5-20% slower.
|
||||||
|
* For consistency with zlib, the decompressor now returns an error
|
||||||
|
on some invalid inputs that were accepted before.
|
||||||
|
* Fixed a build error on arm64 with gcc with certain target CPUs.
|
||||||
|
* Fixed a build error in programs/gzip.c with uClibc.

|
||||||
|
Significantly improved decompression performance on all platforms. Examples
|

|

|
|
||||||
|
- update to 1.13:
|
||||||
|
* Changed the 32-bit Windows build of the library to use the default calling
|
||||||
|
convention (cdecl) instead of stdcall, reverting a change from libdeflate 1.4.
|
||||||
|
* Fixed a couple macOS compatibility issues with the gzip program.

Tue Jul 12 15:21:57 UTC 2022 - Dirk Müller <dmueller@suse.com>
|
||||||
|
|
||||||
|
- update to 1.12:
|
||||||
|
* Improved CRC-32 performance on short inputs on x86 and ARM.
|
||||||
|
* Improved CRC-32 performance on Apple Silicon Macs by using a 12-way pmull
|
||||||
|
implementation. Performance on large inputs on M1 is now about 67 GB/s,
|
||||||
|
compared to 8 GB/s before, or 31 GB/s with the Apple-provided zlib.
|
||||||
|
* Improved CRC-32 performance on some other ARM CPUs by reworking the code so
|
||||||
|
that multiple crc32 instructions can be issued in parallel.
|
||||||
|
* Improved CRC-32 performance on some x86 CPUs by increasing the stride length
|
||||||
|
of the pclmul implementation.
|
||||||
|
* Improved Adler-32 performance on some x86 CPUs by optimizing the AVX-2
|
||||||
|
implementation. E.g., performance on Zen 1 improved from 19 to 30 GB/s, and
|
||||||
|
on Ice Lake from 35 to 41 GB/s (if the AVX-512 implementation is excluded).
|
||||||
|
* Removed the AVX-512 implementation of Adler-32 to avoid CPU frequency
|
||||||
|
downclocking, and because the AVX-2 implementation was made faster.
|
||||||
|
* Improved Adler-32 performance on some ARM CPUs by optimizing the NEON
|
||||||
|
* Improved compression performance slightly.
|
||||||
|
* Detect arm64 CPU features on Apple platforms, which should improve
|
||||||
|
performance in some areas such as CRC-32 computation.
|
||||||
|
* The included `gzip` and `gunzip` programs now support the `-q` option.
|
||||||
|
* The included `gunzip` program now passes through non-gzip data when both
|
||||||
|
the `-f` and `-c` options are used.

Mon Feb 14 23:14:56 UTC 2022 - Dirk Müller <dmueller@suse.com>
|
||||||
|
|
||||||
|
- update to 1.10:
|
||||||
|
* Added an additional check to the decompressor to make it quickly detect
|
||||||
|
certain bad inputs and not try to generate an unbounded amount of output.
|
||||||
|
* Cleaned up a few things in the compression code.
|
||||||
|
|
||||||

|
Mon Jan 24 22:39:11 UTC 2022 - Dirk Müller <dmueller@suse.com>
|
||||||
|
|
||||||
|
- update to 1.9:
|
||||||
|
* Heuristics were implemented which significantly improve the compression
|
||||||
|
ratio on data where short matches aren't useful, such as DNA sequencing
|
||||||
|
data. This applies to all compression levels, but primarily to levels 1-9.
|
||||||
|
* Levels 1 was made much faster, though it often compresses slightly worse
|
||||||
|
than before (but still better than zlib).
|
||||||
|
* Levels 8-9 were also made faster, though they often compress slightly worse
|
||||||
|
than before (but still better than zlib). On some data, levels 8-9 are much
|
||||||
|
faster and compress much better than before; this change addressed an issue
|
||||||
|
where levels 8-9 did poorly on certain files. The algorithm used by levels
|
||||||
|
8-9 is now more similar to that of levels 6-7 than to that of levels 10-12.
|
||||||
|
* Levels 2-3, 7, and 10-12 were strengthened slightly.
|
||||||
|
* Levels 4-6 were also strengthened slightly, but some of this improvement was
|
||||||
|
traded off to speed them up slightly as well.
|
||||||
|
* Levels 1-9 had their per-compressor memory usage greatly reduced.
|
||||||
|
* `make install` will now install a pkg-config file for libdeflate.
|
||||||
|
* The Makefile now supports the `DISABLE_SHARED` parameter to disable building
|
||||||
|
the shared library.

Tue Jan 4 22:37:30 UTC 2022 - Dirk Müller <dmueller@suse.com>
|
||||||
|
|
||||||
|
- update to 1.8:
|
||||||
|
* Added `-t` (test) option to `libdeflate-gunzip`.
|
||||||
|
* Unaligned access optimizations are now enabled on WebAssembly builds.
|
||||||
|
* Fixed a build error when building with the Intel C Compiler (ICC).
|
||||||
|
* Fixed a build error when building with uClibc.
|
||||||
|
* libdeflate's CI system has switched from Travis CI to GitHub Actions.
|
||||||
|
* Made some improvements to test scripts.
