* libmspack is now distributed with its test-suite, which now run
as part of "make check"
* libmspack's programs in src/ have been moved to examples/ and do
not auto-install
Set TEST_TARGET.
New in 1.9
* Fixed invisible bad extraction when using cabextract -F (broken in 1.8)
* Fixed configure --with-external-libmspack which was broken in 1.8
* configure --with-external-libmspack will now use pkg-config. To configure
it manually, set environment variables libmspack_CFLAGS and libmspack_LIBS
before running configure.
* Now includes the test suite (make check)
New in 1.8
* cabextract -f now extracts even more badly damaged files than before
Uptsream changes:
2.32 13/09/2018 (CBERRY)
- Fix absolute path handling on VMS
2.30 19/06/2018
- skip white_space test on MSWin32 as Windows will report that both
files exist, which is obviously a 'feature'
2.1.2:
Improves the speed of importing the module by avoiding the use of pkg_resources
Fixes some flake8 warnings
Resolves a small issue with the test suite when detecting memory usage increases
* On Arch Linux, the build failed, makedev(3) indicates
#include <sys/sysmacros.h>
* On Debian Buster, the build succeed but a big warning is displayed:
warning: In the GNU C Library, "minor" is defined
by <sys/sysmacros.h>. For historical compatibility, it is
currently defined by <sys/types.h> as well, but we plan to
remove this soon. To use "minor", include <sys/sysmacros.h>
directly. If you did not intend to use a system-defined macro
"minor", you should undefine it after including <sys/types.h>.
0.10.1:
Backwards Compatibility Notes
* ZstdCompressor.stream_reader().closed is now a property instead of a
method.
* ZstdDecompressor.stream_reader().closed is now a property instead of a
method.
Changes
* Stop attempting to package Python 3.6 for Miniconda. The latest version of
Miniconda is using Python 3.7. The Python 3.6 Miniconda packages were a lie
since this were built against Python 3.7.
* ZstdCompressor.stream_reader()'s and ZstdDecompressor.stream_reader()'s
closed attribute is now a read-only property instead of a method. This now
properly matches the IOBase API and allows instances to be used in more
places that accept IOBase instances.
0.10.0:
Backwards Compatibility Notes
* ZstdDecompressor.stream_reader().read() now consistently requires an
argument in both the C and CFFI backends. Before, the CFFI implementation
would assume a default value of -1, which was later rejected.
* The compress_literals argument and attribute has been removed from
zstd.ZstdCompressionParameters because it was removed by the zstd 1.3.5
API.
* ZSTD_CCtx_setParametersUsingCCtxParams() is no longer called on every
operation performed against ZstdCompressor instances. The reason for this
change is that the zstd 1.3.5 API no longer allows this without calling
ZSTD_CCtx_resetParameters() first. But if we called
ZSTD_CCtx_resetParameters() on every operation, we'd have to redo
potentially expensive setup when using dictionaries. We now call
ZSTD_CCtx_reset() on every operation and don't attempt to change
compression parameters.
* Objects returned by ZstdCompressor.stream_reader() no longer need to be
used as a context manager. The context manager interface still exists and its
behavior is unchanged.
* Objects returned by ZstdDecompressor.stream_reader() no longer need to be
used as a context manager. The context manager interface still exists and its
behavior is unchanged.
Bug Fixes
* ZstdDecompressor.decompressobj().decompress() should now return all data
from internal buffers in more scenarios. Before, it was possible for data to
remain in internal buffers. This data would be emitted on a subsequent call
to decompress(). The overall output stream would still be valid. But if
callers were expecting input data to exactly map to output data (say the
producer had used flush(COMPRESSOBJ_FLUSH_BLOCK) and was attempting to
map input chunks to output chunks), then the previous behavior would be
wrong. The new behavior is such that output from
flush(COMPRESSOBJ_FLUSH_BLOCK) fed into decompressobj().decompress()
should produce all available compressed input.
* ZstdDecompressor.stream_reader().read() should no longer segfault after
a previous context manager resulted in error.
* ZstdCompressor.compressobj().flush(COMPRESSOBJ_FLUSH_BLOCK) now returns
all data necessary to flush a block. Before, it was possible for the
flush() to not emit all data necessary to fully represent a block. This
would mean decompressors wouldn't be able to decompress all data that had been
fed into the compressor and flush()ed.
New Features
* New module constants BLOCKSIZELOG_MAX, BLOCKSIZE_MAX,
TARGETLENGTH_MAX that expose constants from libzstd.
* New ZstdCompressor.chunker() API for manually feeding data into a
compressor and emitting chunks of a fixed size. Like compressobj(), the
API doesn't impose restrictions on the input or output types for the
data streams. Unlike compressobj(), it ensures output chunks are of a
fixed size. This makes this API useful when the compressed output is being
fed into an I/O layer, where uniform write sizes are useful.
* ZstdCompressor.stream_reader() no longer needs to be used as a context
manager.
* ZstdDecompressor.stream_reader() no longer needs to be used as a context
manager.
* Bundled zstandard library upgraded from 1.3.4 to 1.3.6.
Changes
* Added zstd_cffi.py and NEWS.rst to MANIFEST.in.
* zstandard.__version__ is now defined.
* Upgrade pip, setuptools, wheel, and cibuildwheel packages to latest versions.
* Upgrade various packages used in CI to latest versions. Notably tox (in
order to support Python 3.7).
* Use relative paths in setup.py to appease Python 3.7.
* Added CI for Python 3.7.
Zstandard v1.3.7
perf: slightly better decompression speed on clang (depending on hardware target)
fix: ratio for dictionary compression at levels 9 and 10, reported by @indygreg
build: no longer build backtrace by default in release mode; restrict further automatic mode
build: control backtrace support through build macro BACKTRACE
misc: added man pages for zstdless and zstdgrep, by @samrussell
Zstandard v1.3.6 release is focused on intensive dictionary compression for database scenarios.
This is a new environment we are experimenting. The success of dictionary compression on small data, of which databases tend to store plentiful, led to increased adoption, and we now see scenarios where literally thousands of dictionaries are being used simultaneously, with permanent generation or update of new dictionaries.
== 1.0.0 (2018-05-20)
* *BreakingChange* The XZ module's methods now take any parameters
beyond the IO object as real Ruby keyword arguments rather than
a long argument list.
* *BreakingChange* XZ.decompress_stream now honours Ruby's
external and internal encoding concept instead of just
returning BINARY-tagged strings.
* *BreakingChange* Remove deprecated API on stream reader/writer
class and instead sync the API with Ruby's zlib library
(Ticket #12 by me).
* *BreakingChange* StreamWriter.new and StreamReader.new do not accept
a block anymore. This is part of syncing with Ruby's zlib API.
* *BreakingChange* StreamReader.open and StreamWriter.open always
return the new instance, even if a block is given to the method
(previous behaviour was to return the return value of the block).
This is part of the syncing with Ruby's zlib API.
* *BreakingChange* StreamReader.new and StreamWriter.new as well as
the ::open variants take additional arguments as real Ruby keyword
arguments now instead of a long parameter list plus options hash.
This is different from Ruby's own zlib API as that one takes both
a long parameter list and a hash of additional options. ruby-xz
is meant to follow zlib's semantics mostly, but not as a drop-in
replacement, so this divergence from zlib's API is okay (also
given that it isn't possible to replicate all possible options
1:1 anyway, since liblzma simply accepts different options as
libz). If you've never used these methods' optional arguments,
you should be fine.
* *BreakingChange* Stream#close now returns nil instead of the
number of bytes written. This syncs Stream#close with Ruby's
own IO#close, which also returns nil.
* *BreakingChange* Remove Stream#pos=, Stream#seek, Stream#stat. These
methods irritated the minitar gem, which doesn't expect them to
raise NotImplementedError, but directly to be missing if the object
does not support seeking.
* *BreakingChange* StreamReader and StreamWriter now honour Ruby's
encoding system instead of returning only BINARY-tagged strings.
* *Dependency* Remove dependency on ffi. ruby-xz now uses fiddle from
the stdlib instead.
* *Dependency* Remove dependency on io-like. ruby-xz now implements
all the IO mechanics itself. (Ticket #10 by me)
* *Dependency* Bump required Ruby version to 2.3.0.
* *Fix* libzlma.dylib not being found on OS X (Ticket #15 by
s0nspark).
- perf: minor decompression speed improvement (~+2%) with gcc
- fix : corruption in v1.8.2 at level 9 for files > 64KB under rare
conditions (#560)
- cli : new command --fast, by @jennifermliu
- api : LZ4_decompress_safe_partial() now decodes exactly the nb of
bytes requested (feature request #566)
- build : added Haiku target, by @fbrosson, and MidnightBSD, by @laffer1
- doc : updated documentation regarding dictionary compression
This is based on the decision The NetBSD Foundation made in 2008 to
do so, which was already applied to src.
This change has been applied to code which is likely not in other
repositories.

2018-04-26 Stuart Caie <kyzer@cabextract.org.uk>
* read_chunk(): the test that chunk numbers are in bounds was off
by one, so read_chunk() returned a pointer taken from outside
allocated memory that usually crashes libmspack when accessed.
Thanks to Hanno Böck for finding the issue and providing a sample.
* chmd_read_headers(): reject files with blank filenames. Thanks
again to Hanno Böck for finding the issue and providing a sample file.
2018-02-06 Stuart Caie <kyzer@cabextract.org.uk>
* chmd.c: fixed an off-by-one error in the TOLOWER() macro, reported

2017-08-13 Stuart Caie <kyzer@cabextract.org.uk>
* src/chmextract.c: support MinGW one-arg mkdir(). Thanks to AntumDeluge
for reporting this.
2017-08-13 Stuart Caie <kyzer@cabextract.org.uk>
* read_spaninfo(): a CHM file can have no ResetTable and have a
negative length in SpanInfo, which then feeds a negative output length
to lzxd_init(), which then sets frame_size to a value of your choosing,
the lower 32 bits of output length, larger than LZX_FRAME_SIZE. If the
first LZX block is uncompressed, this writes data beyond the end of the
window. This issue was raised by ClamAV as CVE-2017-6419. Thanks to
Sebastian Andrzej Siewior for finding this by chance!
* lzxd_init(), lzxd_set_output_length(), mszipd_init(): due to the issue
mentioned above, these functions now reject negative lengths
2017-08-05 Stuart Caie <kyzer@cabextract.org.uk>
* cabd_read_string(): add missing error check on result of read().
If an mspack_system implementation returns an error, it's interpreted
as a huge positive integer, which leads to reading past the end of the
stack-based buffer. Thanks to Sebastian Andrzej Siewior for explaining
the problem. This issue was raised by ClamAV as CVE-2017-11423

New in 1.7
* cabextract now supports an --encoding parameter, to specify the character
encoding of CAB filenames if they are not ASCII or UTF8

It's now possible to specify a compession dictionary for block compression.
The bundled LZ4 libraries have been updated to 1.8.2
A compatibility fix for 2.x memoryview objects has been added.

headers when a C++11 (or newer standard) compiler is used.
- Added a portability fix for recent Intel C Compilers.
- Microsoft Visual Studio build files have been moved under
windows/vs2013 and windows/vs2017.
* xz:
- Fix "xz --list --robot missing_or_bad_file.xz" which would
try to print an unitialized string and thus produce garbage
output. Since the exit status is non-zero, most uses of such
a command won't try to interpret the garbage output.
- "xz --list foo.xz" could print "Internal error (bug)" in a
corner case where a specific memory usage limit had been set.

0.9.0:
Backwards Compatibility Notes
CFFI 1.11 or newer is now required (previous requirement was 1.8).
The primary module is now zstandard. Please change imports of zstd and zstd_cffi to import zstandard. See the README for more. Support for importing the old names will be dropped in the next release.
ZstdCompressor.read_from() and ZstdDecompressor.read_from() have been renamed to read_to_iter(). read_from() is aliased to the new name and will be deleted in a future release.
Support for Python 2.6 has been removed.
Support for Python 3.3 has been removed.
The selectivity argument to train_dictionary() has been removed, as the feature disappeared from zstd 1.3.
Support for legacy dictionaries has been removed. Cover dictionaries are now the default. train_cover_dictionary() has effectively been renamed to train_dictionary().
The allow_empty argument from ZstdCompressor.compress() has been deleted and the method now allows empty inputs to be compressed by default.
estimate_compression_context_size() has been removed. Use CompressionParameters.estimated_compression_context_size() instead.
get_compression_parameters() has been removed. Use CompressionParameters.from_level() instead.
The arguments to CompressionParameters.__init__() have changed. If you were using positional arguments before, the positions now map to different arguments. It is recommended to use keyword arguments to construct CompressionParameters instances.
TARGETLENGTH_MAX constant has been removed (it disappeared from zstandard 1.3.4).
ZstdCompressor.write_to() and ZstdDecompressor.write_to() have been renamed to ZstdCompressor.stream_writer() and ZstdDecompressor.stream_writer(), respectively. The old names are still aliased, but will be removed in the next major release.
Content sizes are written into frame headers by default (ZstdCompressor(write_content_size=True) is now the default).
CompressionParameters has been renamed to ZstdCompressionParameters for consistency with other types. The old name is an alias and will be removed in the next major release.
Bug Fixes
Fixed memory leak in ZstdCompressor.copy_stream().
Fixed memory leak in ZstdDecompressor.copy_stream().
Fixed memory leak of ZSTD_DDict instances in CFFI's ZstdDecompressor.
New Features
Bundlded zstandard library upgraded from 1.1.3 to 1.3.4. This delivers various bug fixes and performance improvements. It also gives us access to newer features.
Support for negative compression levels.
Support for long distance matching (facilitates compression ratios that approach LZMA).
Supporting for reading empty zstandard frames (with an embedded content size of 0).
Support for writing and partial support for reading zstandard frames without a magic header.
New stream_reader() API that exposes the io.RawIOBase interface (allows you to .read() from a file-like object).
Several minor features, bug fixes, and performance enhancements.
Wheels for Linux and macOS are now provided with releases.
Changes
Functions accepting bytes data now use the buffer protocol and can accept more types (like memoryview and bytearray).
Add #includes so compilation on OS X and BSDs works.
New ZstdDecompressor.stream_reader() API to obtain a read-only i/o stream of decompressed data for a source.
New ZstdCompressor.stream_reader() API to obtain a read-only i/o stream of compressed data for a source.
Renamed ZstdDecompressor.read_from() to ZstdDecompressor.read_to_iter(). The old name is still available.
Renamed ZstdCompressor.read_from() to ZstdCompressor.read_to_iter(). read_from() is still available at its old location.
Introduce the zstandard module to import and re-export the C or CFFI backend as appropriate. Behavior can be controlled via the PYTHON_ZSTANDARD_IMPORT_POLICY environment variable. See README for usage info.
Vendored version of zstd upgraded to 1.3.4.
Added module constants CONTENTSIZE_UNKNOWN and CONTENTSIZE_ERROR.
Add STRATEGY_BTULTRA compression strategy constant.
Switch from deprecated ZSTD_getDecompressedSize() to ZSTD_getFrameContentSize() replacement.
ZstdCompressor.compress() can now compress empty inputs without requiring special handling.
ZstdCompressor and ZstdDecompressor now have a memory_size() method for determining the current memory utilization of the underlying zstd primitive.
train_dictionary() has new arguments and functionality for trying multiple variations of COVER parameters and selecting the best one.
Added module constants LDM_MINMATCH_MIN, LDM_MINMATCH_MAX, and LDM_BUCKETSIZELOG_MAX.
Converted all consumers to the zstandard new advanced API, which uses ZSTD_compress_generic()
CompressionParameters.__init__ now accepts several more arguments, including support for long distance matching.
ZstdCompressionDict.__init__ now accepts a dict_type argument that controls how the dictionary should be interpreted. This can be used to force the use of content-only dictionaries or to require the presence of the dictionary magic header.
ZstdCompressionDict.precompute_compress() can be used to precompute the compression dictionary so it can efficiently be used with multiple ZstdCompressor instances.
Digested dictionaries are now stored in ZstdCompressionDict instances, created automatically on first use, and automatically reused by all ZstdDecompressor instances bound to that dictionary.
All meaningful functions now accept keyword arguments.
ZstdDecompressor.decompressobj() now accepts a write_size argument to control how much work to perform on every decompressor invocation.
ZstdCompressor.write_to() now exposes a tell(), which exposes the total number of bytes written so far.
ZstdDecompressor.stream_reader() now supports seek() when moving forward in the stream.
Removed TARGETLENGTH_MAX constant.
Added frame_header_size(data) function.
Added frame_content_size(data) function.
Consumers of ZSTD_decompress* have been switched to the new advanced decompression API.
ZstdCompressor and ZstdCompressionParams can now be constructed with negative compression levels.
ZstdDecompressor now accepts a max_window_size argument to limit the amount of memory required for decompression operations.
FORMAT_ZSTD1 and FORMAT_ZSTD1_MAGICLESS constants to be used with the format compression parameter to control whether the frame magic header is written.
ZstdDecompressor now accepts a format argument to control the expected frame format.
ZstdCompressor now has a frame_progression() method to return information about the current compression operation.
Error messages in CFFI no longer have b'' literals.
Compiler warnings and underlying overflow issues on 32-bit platforms have been fixed.
Builds in CI now build with compiler warnings as errors. This should hopefully fix new compiler warnings from being introduced.
Make ZstdCompressor(write_content_size=True) and CompressionParameters(write_content_size=True) the default.
CompressionParameters has been renamed to ZstdCompressionParameters.
1.1.0:
This release removes the deprecated functions which were marked as remove in 1.0, but nonetheless remained:
lz4.lz4version()
LZ4FrameCompressor.finalize()
As a side effect, we noo longer have a dependency on the deprecation package.
1.5.0 [2018-03-11]
==================
* Use standard cryptographic library instead of custom AES implementation.
This also simplifies the license.
* Use `clang-format` to format the source code.
* More Windows improvements.
version 1.30 - Sergey Poznyakoff, 2017-12-17
* Member names containing '..' components are now skipped when extracting.
This fixes tar's behavior to match its documentation, and is a bit
safer when extracting untrusted archives over old files (an unsafe
practice that the tar manual has long recommended against).
* Report erroneous use of position-sensitive options.
During archive creation or update, tar keeps track of positional
options (see the manual, subsection 3.4.4 "Position-Sensitive
Options"), and reports those that had no effect. For example, when
invoked as
tar -cf a.tar . --exclude '*.o'
tar will create the archive, but will exit with status 2, having
issued the following error message
tar: The following options were used after non-optional
arguments in archive create or update mode. These options are
positional and affect only arguments that follow them. Please,
rearrange them properly.
tar: --exclude '*.o' has no effect
tar: Exiting with failure status due to previous errors
* --numeric-owner now affects private headers too.
This helps the output of 'tar' to be more deterministic.
* Fixed the --delay-directory-restore option
In some cases tar would restore the directory permissions too early,
causing subsequent link extractions in that directory to fail.
* The --warnings=failed-read option
This new warning control option suppresses warning messages about
unreadable files and directories. It has effect only if used together
with the --ignore-failed-read option.
* The --warnings=none option now suppresses all warnings
This includes warnings about unreadable files produced when
--ignore-failed-read is in effect. To output these, use
--warnings=none --warnings=no-failed-read.
* Fix reporting of hardlink mismatches during compare
Tar reported incorrect target file name in the 'Not linked to'
diagnostic message.
Changes in version 1.20:
The option '--loose-trailing', has been added.
The test used by lzip 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 lzip's output" has been added to the manual.
Changelog:
2018-02-02 guidod <guidod@gmx.de>
* fix a number of CVEs reported with special *.zip files
* the testsuite has been expanded to cover all the CVEs
* some minor doc updates referencing GitHub instead of sf.net
* release v0.13.68
0.23.2:
Fixes an error in the deprecated LZ4Compressor.finalize() method
Improves documentation
Has all example code in documentation verified via doctest
Skip running the regression tests since for some reason the setting
of LD_LIBRARY_PATH isn't passed down through cmake invocation; this
avoids error:
dyld: Library not loaded: @rpath/libzip.5.dylib
Referenced from: ${WRKSRC}/regress/../src/ziptool
Reason: image not found
The module has bundled version 1.1.2, but the configure script warns
when using the bundled one, and it's of course better to not duplicate
it. Noticed this on recent PHP 7.1.14/7.2.2 releases which had fixes
for zip extension when used with libzip >= 1.3.1.
XXX May need backport of the fix for 7.0 and 5.6 which did not get the fix,
or can just switch over to using the PECL module directly
0.19.1:
This release adds compressed file handling capability to the lz4.frame sub-package.
This necessitated some changes to the API of lz4.frame.decompress_chunk, ad some smaller changes to the LZ4FrameCompressor and LZ4FrameDecompressor classes. Please see updated documentation for further details.
This is a build-maintenance release. Major changes:
added Autotools build files
switched shared library version to libtool scheme
In this release semantic suffix and libtool suffix are the same: 1.0.2.
Don't expect them to match in future releases.
Minor changes:
BrotliDictionary members are not const now
ZopfliNode distance could be up to 128MiB
fixed API documentation typos
total_out is always set by decoder
fixed BROTLI_ENSURE_CAPACITY macro; no-op in preprocessed output
Other changes:
fixed scripts for oss-fuzz, test them with Travis
made Bazel JNI tests less messy
fixed linter warnings in JS decoder
fixed permissions of various files
added Bazel build to Appveyor matrix
added Sieve dictionary generator
0.18.2:
This release fixes a memory leak that was introduced in lz4.frame.decompress in 0.18.1. This leak resulted from an incorrect ref count on the returned result which prevented it from ever being released and garbage collected.
v1.8.1.2:
It's the same as v1.8.1, but the version number in source code has been fixed.
The version number is used in cli and documentation display, to create the full name of dynamic library, and can be requested via LZ4_versionNumber().
v1.8.1
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 -jX
build : can control LZ4LIB_VISIBILITY macro
install: fix man page directory
The actual fix as been done by "pkglint -F */*/buildlink3.mk", and was
reviewed manually.
There are some .include lines that still are indented with zero spaces
although the surrounding .if is indented. This is existing practice.
- Generate Zip64 format .zip files when the output is greater than
or equal to 4 GiB.
- Improved gzip options processing and return code compatibility
- Some bug fixes
0.18.1:
This is a minor bugfix release which fixes two small bugs which would result in source references not being released on error conditions in lz4.frame.compress.
0.18.0:
This release changes the strategy for allocating memory to not use undocumented and potentially fragile Python internals (Py_SIZE). This may have a small performance impact, but brings stronger guarantees for future stability.
Unsorted entries in PLIST files have generated a pkglint warning for at
least 12 years. Somewhat more recently, pkglint has learned to sort
PLIST files automatically. Since pkglint 5.4.23, the sorting is only
done in obvious, simple cases. These have been applied by running:
pkglint -Cnone,PLIST -Wnone,plist-sort -r -F
0.17.0:
This release fixes a pathological case where compressing and decompressing a zero length bytes object could result in the resulting bytes object causing False to be returned from val == 'b'.
1.4.0 [2017-12-29]
==================
* Improve build with cmake
* Retire autoconf/automake build system
* Add `zip_source_buffer_fragment()`.
* Add support to clone unchanged beginning of archive (instead of rewriting it).
Supported for buffer sources and on Apple File System.
* Add support for Microsoft Universal Windows Platform.
1.3.3:
perf: improved zstd_opt strategy (levels 16-19)
fix : bug 944 : multithreading with shared ditionary and large data
cli : fix : content size written in header by default
cli : fix : improved LZ4 format support
cli : new : hidden command -b -S, to benchmark multiple files and generate one result per file
api : change : when setting pledgedSrcSize, use ZSTD_CONTENTSIZE_UNKNOWN macro value to mean "unknown"
api : fix : support large skippable frames
api : fix : re-using context could result in suboptimal block size in some corner case scenarios
api : fix : streaming interface was adding a useless 3-bytes null block to small frames
build: fix : compilation under rhel6 and centos6
build: added check target
build: improved meson support
This release brings
Huge changes to the LZ4 Frame support which should now be considered beta quality
A new pytest based test harness, and significantly re-worked testing
An end to Python 2.6 support - no testing is currently done against Python 2.6 although the code probably does still work with Python 2.6 at this point in time.
atool is a script for managing file archives of various types (tar,
tar+gzip, zip, etc.). It provides the following commands:
* aunpack: extract an archive, avoiding tar bombs
* apack: create archives or compressed files
* als: list the contents of an archive
* acat: extract to the standard output
* adiff: generate a diff between two archives
* arepack: repack archives to a different format
Optional dependencies: lbzip2 or pbzip2, lzip, plzip, lzop, lzma, zip,
unzip, unrar, lha, unace, arj, arc, nomarch, p7zip, unalz.
Brotli is a generic-purpose lossless compression algorithm that compresses data
using a combination of a modern variant of the LZ77 algorithm, Huffman coding
and 2nd order context modeling, with a compression ratio comparable to the best
currently available general-purpose compression methods. It is similar in speed
with deflate but offers more dense compression.
0.8.1:
Add #includes so compilation on OS X and BSDs works.
0.8.0:
CompressionParameters now has a estimated_compression_context_size() method. zstd.estimate_compression_context_size() is now deprecated and slated for removal.
Implemented a lot of fuzzing tests.
CompressionParameters instances now perform extra validation by calling ZSTD_checkCParams() at construction time.
multi_compress_to_buffer() API for compressing multiple inputs as a single operation, as efficiently as possible.
ZSTD_CStream instances are now used across multiple operations on ZstdCompressor instances, resulting in much better performance for APIs that do streaming.
ZSTD_DStream instances are now used across multiple operations on ZstdDecompressor instances, resulting in much better performance for APIs that do streaming.
train_dictionary() now releases the GIL.
Support for training dictionaries using the COVER algorithm.
multi_decompress_to_buffer() API for decompressing multiple frames as a single operation, as efficiently as possible.
Support for multi-threaded compression.
Disable deprecation warnings when compiling CFFI module.
Fixed memory leak in train_dictionary().
Removed DictParameters type.
train_dictionary() now accepts keyword arguments instead of a DictParameters instance to control dictionary generation.

license : fix a few header files to reflect new license
py-lz4 provides Python bindings for the LZ4 compression library by Yann
Collet.
At this time the project contains bindings for the LZ4 block format,
which are considered stable.
Support for the LZ4 frame format is a work-in-progress and available as a
technology preview. A future relase will implement support for the LZ4
stream format.
Temporarily remove the zstd buildlink as py-zstandard includes
its own version that it wants to use. Future versions will
support using a system supplied zstd but this one doesn't yet.
Also prevent setup.py from picking up cffi by accident so the
PLIST is stable.
New license : BSD + GPLv2

'--merge' is now able to fix files with thousands of scattered errors
per member by grouping the errors into clusters and then merging the
files as if each cluster were a single error.
The option '-a, --trailing-error' now works with '-l, --list' and
'-D, --range-decompress'.
The output of option '-l, --list' has been simplified to make it easier
to read.
In test mode, lziprecover now continues checking the rest of the files
if any input file is a terminal.
Trailing data are now shown both in hexadecimal and as a string of
printable ASCII characters.
The option '-l, --list' has been ported from lziprecover.
It is now an error to specify two or more different operations in the
command line (--decompress, --list or --test).
Compression time of option '-0' has been slightly reduced.
Decompression time has been reduced by 2%.
In test mode, lzip now continues checking the rest of the files if any

zzip_disk_entry_check_magic to be after the the check that
the seek-value is more than a header's size before the end.

minitar-cli is a pure-Ruby command-line tool that uses to provide a
command-line tool, minitar, for working with POSIX tar(1) archive
files.
This is release 0.6, extracted from minitar(*) with modernizations.
* https://halostatue.ca/minitar
The minitar library is a pure-Ruby library that provides the ability to deal
with POSIX tar(1) archive files.
This is release 0.6, providing a number of bug fixes including a directory
traversal vulnerability, CVE-2016-10173. This release starts the migration and
modernization of the code:
* the licence has been changed to match the modern Ruby licensing scheme
(Ruby and Simplified BSD instead of Ruby and GNU GPL);
* the +minitar+ command-line program has been separated into the
+minitar-cli+ gem; and
* the +archive-tar-minitar+ gem now points to the +minitar+ and +minitar-cli+
gems and discourages its installation.
Some of these changes may break existing programs that depend on the internal
structure of the minitar library, but every effort has been made to ensure
compatibility; inasmuch as is possible, this compatibility will be maintained
through the release of minitar 1.0 (which will have strong breaking changes).
minitar (previously called Archive::Tar::Minitar) is based heavily on code
originally written by Mauricio Julio Fern\u{e1}ndez Pradier for the rpa-base
project.
Darwin ACL: avoid using mbr_identifier_to_uuid()
Use mbr_uid_to_uuid() and mbr_gid_to_uuid() for backwards compatibility
instead. These functions have been introduced together with membership.h.
This project provides Python bindings for interfacing with the
Zstandard compression library. A C extension and CFFI interface are
provided.
The primary goal of the project is to provide a rich interface to
the underlying C API through a Pythonic interface while not sacrificing
performance. This means exposing most of the features and flexibility
of the C API while not sacrificing usability or safety that Python
provides.
Changes in 2.10 (01 Mar 2017)
* Improve CMake build support.
* Add support for pkg-config.
* Do not redefine "snprintf" so that the examples build with MSVC 2015.
* Assorted cleanups.
