|
|
- Update to version 0.20.0
|
|||
|
|
* This will likely be the last release officially supporting Python 3.6.
|
|||
|
|
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.

|
|
- 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).

|

|
|
|
|||
|
|
- 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.

|
|||
|
|
|
|||
|
|
- 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.

|
|||
|
|
|
|||
|
|
- update to 0.14.0
|
|||
|
|
* This will likely be the final version supporting Python 2.7. Future
|
|||
|
|
releases will likely only work on Python 3.5+. See #109 for more
|
|||
|
|
context.
|
|||
|
|
* There is a significant possibility that future versions will use
|
|||
|
|
Rust - instead of C - for compiled code. See #110 for more context.
|
|||
|
|
* Some internal fields of C structs are now explicitly initialized.
|
|||
|
|
(Possible fix for #105.)
|
|||
|
|
* The ``make_cffi.py`` script used to build the CFFI bindings now
|
|||
|
|
calls ``distutils.sysconfig.customize_compiler()`` so compiler
|
|||
|
|
customizations (such as honoring the ``CC`` environment variable)
|
|||
|
|
are performed. Patch by @Arfrever. (#103)
|
|||
|
|
* The ``make_cffi.py`` script now sets ``LC_ALL=C`` when invoking
|
|||
|
|
the preprocessor in an attempt to normalize output to ASCII. (#95)

|
|
|
|||
|
|
- version update to 0.13.0
|
|||
|
|
* ``pytest-xdist`` ``pytest`` extension is now installed so tests can be
|
|||
|
|
run in parallel.
|
|||
|
|
* CI now builds ``manylinux2010`` and ``manylinux2014`` binary wheels
|
|||
|
|
instead of a mix of ``manylinux2010`` and ``manylinux1``.
|
|||
|
|
* Official support for Python 3.8 has been added.
|
|||
|
|
* Bundled zstandard library upgraded from 1.4.3 to 1.4.4.
|
|||
|
|
* Python code has been reformatted with black.
