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.
v1.3.2

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.

* SDL/Makefile.am: fix generation of sdl-uninstalled.pc that was
not recognized during compilation.
2010-04-05 guidod <guidod@gmx.de>
* Makefile.am: fix "osc rm" and fix "test-sdl" if SDL was not found.
* configure.ac: SDL example builds on pkgconfig/sdl.pc which
was introduced with SDL 1.2.11 - CentOs5 ships 1.2.10 which
does only have "sdl-config" and it made for a mismatch in
in the build configuration: sdl-devel yes, pkgconfig sdl no.

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.
(based on a segfault report by Tulipánt Gergely when the
new modulo_entries code is enabled (which is off by default))

* zzip/Makefile.am: fixing symlinks for lib* - use only for Linux
Thanks to Ryan Schmidt (macports):
... likes to install some symlinks that don't make sense on Mac OS X:
$ ls -l /opt/local/lib/*zzip*so*
lrwxr-xr-x /opt/local/lib/libzzip*.so.10 -> libzzip*.so.13

Features:
* Supports both RAR3 and RAR5 format archives.
* Supports multi volume archives.
* Supports Unicode filenames.
* Supports password-protected archives.
* Supports archive and file comments.
* Archive parsing and non-compressed files are handled in pure Python code.
* Compressed files are extracted by executing external tool: either unrar from
RARLAB or bsdtar from libarchive.
* Works with both Python 2.7 and 3.x.
Brotlipy is a collection of CFFI-based bindings to the Brotli
compression reference implementation as written by Google. This
enables Python software to easily and quickly work with the Brotli
compression algorithm, regardless of what interpreter is being
used.
