Zstandard bindings for Python
BSD-3-Clause
* Tue Mar 05 2024 Dominique Leuenberger <dimstar@opensuse.org>
- Use %autosetup macro. Allows us to eliminate usage of deprecated
%patchN.
* Thu Dec 28 2023 ecsos <ecsos@opensuse.org>
- Add %{?sle15_python_module_pythons}
* Sat Nov 04 2023 Bernhard Wiedemann <bwiedemann@suse.de>
- Update to version 0.22.0
* Official support for CPython 3.12
* ZstdDecompressor.decompressobj() now accepts a read_across_frames
boolean named argument to control whether to transparently read across
multiple zstd frames. It still defaults to False to preserve existing
behavior
* Wed Apr 19 2023 Bernhard Wiedemann <bwiedemann@suse.com>
- Update to version 0.21.0
* Support zstd 1.5.5
* Tue Feb 21 2023 Martin Liška <mliska@suse.cz>

Python 3.6 is end of life as of 2021-12-23.
* Bundled zstd library upgraded from 1.5.2 to 1.5.4.
* Use of the deprecated ZSTD_copyDCtx() was removed from the C and
Rust backends.
* Fri Feb 17 2023 Martin Liška <mliska@suse.cz>
- Enable --system-zstd so that we depend of a system shared library
of zstd.
- Add feature-detection.patch as feature detection test does not support
- -system-zstd (gh#indygreg/python-zstandard#191).
* Mon Dec 05 2022 Yogalakshmi Arunachalam <yarunachalam@suse.com>
- Fixed spec file to include exceptiongroup
* Sun Nov 20 2022 Mia Herkt <mia@0x0.st>
- Update to 0.19.0
Bug fixes
* The C backend implementation of
ZstdDecompressionObj.decompress() could have raised an
assertion in cases where the function was called multiple times
on an instance. In non-debug builds, calls to this method could
have leaked memory.
Changes
* PyPy 3.6 support dropped; Pypy 3.8 and 3.9 support added.
* Anaconda 3.6 support dropped.
* Official support for Python 3.11. This did not require
meaningful code changes and previous release(s) likely worked
with 3.11 without any changes. CFFI's build system now respects
distutils's compiler.preprocessor if it is set.
gh#indygreg/python-zstandard#179
* The internal logic of ZstdDecompressionObj.decompress() was
refactored. This may have fixed unconfirmed issues where
unused_data was set prematurely. The new logic will also avoid
an extra call to ZSTD_decompressStream() in some scenarios,
possibly improving performance.
* ZstdDecompressor.decompress() how has a read_across_frames
keyword argument. It defaults to False. True is not yet
implemented and will raise an exception if used. The new
argument will default to True in a future release and is
provided now so callers can start passing
read_across_frames=False to preserve the existing functionality
during a future upgrade.
* ZstdDecompressor.decompress() now has an allow_extra_data
keyword argument to control whether an exception is raised if
input contains extra data. It defaults to True, preserving
existing behavior of ignoring extra data. It will likely
default to False in a future release. Callers desiring the
current behavior are encouraged to explicitly pass
allow_extra_data=True so behavior won't change during a future
upgrade.
- No changelog for 0.18.0 available
* Tue Feb 01 2022 Ben Greiner <code@bnavigator.de>
- Correctly test the installed solib
- Skip python2 on SLE/Leap: no longer supported
* Sun Jan 30 2022 Sarah Kriesch <sarah.kriesch@opensuse.org>
- update to 0.17.0
* Python 3.9 wheels are now provided.
* Support for Python 3.5 has been dropped.
* Python 3.6 is now the minimum required Python version.
* Bundled zstandard library upgraded from 1.4.5 to 1.5.1.
* The bundled zstandard library is now using the single C source
file distribution. The 2 main header files are still present,
as these are needed by CFFI to generate the CFFI bindings.
* PyBuffer instances are no longer checked to be C contiguous and
have a single dimension. The former was redundant with what
PyArg_ParseTuple() already did and the latter is not necessary
in practice because very few extension modules create buffers
with more than 1 dimension. (#124)
* Added Python typing stub file for the zstandard module. (#120)
* The make_cffi.py script should now respect the CC environment
variable for locating the compiler. (#103)
* CI now properly uses the cffi backend when running all tests.
* train_dictionary() has been rewritten to use the fastcover APIs
and to consistently call ZDICT_optimizeTrainFromBuffer_fastCover()
instead of different C APIs depending on what arguments were passed.
The function also now accepts arguments f, split_point, and accel,
which are parameters unique to fastcover.
* CI now tests and builds wheels for Python 3.9.
* zstd.c file renamed to c-ext/backend_c.c.
* All built/installed Python modules are now in the zstandard package.
Previously, there were modules in other packages. (#115)
* C source code is now automatically formatted with clang-format.
* ZstdCompressor.stream_writer(), ZstdCompressor.stream_reader(),
ZstdDecompressor.stream_writer(), and ZstdDecompressor.stream_reader()
now accept a closed argument to control whether the underlying stream
should be closed when the ZstdCompressionWriter, ZstdCompressReader,
ZstdDecompressionWriter, or ZstdDecompressionReader is closed. (#76)
* There is now a zstandard.open() function for returning a file object
with zstd (de)compression. (#64)
* The zstandard module now exposes a backend_features attribute
containing a set of strings denoting optional features present in that
backend. This can be used to sniff feature support by performing a
string lookup instead of sniffing for API presence or behavior.
* Python docstrings have been moved from the C backend to the CFFI backend.
Sphinx docs have been updated to generate API documentation via the CFFI
backend. Documentation for Python APIs is now fully defined via Python
docstrings instead of spread across Sphinx ReST files and source code.
* ZstdCompressionParameters now exposes a strategy property.
* There are now compress() and decompress() convenience functions on the
zstandard module. These are simply wrappers around the corresponding APIs
on ZstdCompressor and ZstdDecompressor.
* The deprecated CompressionParameters type alias to ZstdCompressionParamaters
has been removed. Use ZstdCompressionParameters.
* setup.py now recognizes a ZSTD_EXTRA_COMPILER_ARGS environment variable to
specify additional compiler arguments to use when compiling the C backend.
* PyPy build and test coverage has been added to CI.
* Added CI jobs for building against external zstd library.
* Wheels supporting macOS ARM/M1 devices are now being produced.
* References to Python 2 have been removed from the in-repo Debian packaging code.
* Significant work has been made on a Rust backend. It is currently feature
complete but not yet optimized. We are not yet shipping the backend as part
of the distributed wheels until it is more mature.
* ZstdCompressor.multi_compress_to_buffer() and ZstdDecompressor.multi_decompress_to_buffer()
are no longer available when linking against a system zstd library.
These experimental features are only available when building against the
bundled single file zstd C source file distribution. (#106)
* The .pyi type annotations file has replaced various default argument
values with ....
* manylinux2014_aarch64 wheels are now being produced for CPython 3.6+. (#145).
* Wheels are now being produced for CPython 3.10.
* Arguments to ZstdCompressor() and ZstdDecompressor() are now all optional in
the C backend and an explicit None value is accepted. Before, the C backend
wouldn’t accept an explicit None value (but the CFFI backend would).
The new behavior should be consistent between the backends. (#153)
* The C backend now exposes the symbols ZstdCompressionReader, ZstdCompressionWriter,
ZstdDecompressionReader, and ZstdDecompressionWriter. This should match the behavior
of the CFFI backend. (#165)
* ZstdCompressionWriter and ZstdDecompressionWriter now
implement __iter__ and __next__, which always raise io.UnsupportedOperation.
* Documentation on thread safety has been updated to note that derived objects like
ZstdCompressionWriter have the same thread unsafety as the contexts they were
derived from. (#166)
* The HASHLOG3_MAX constant has been removed since it is no longer defined in zstd 1.5.1.
