Log message: py-zstandard: fix build with zstd 1.5.6 Bump PKGREVISION. |
2023-11-06 21:00:39 by Thomas Klausner | Files touched by this commit (3) |  |
Log message:
py-zstandard: update to 0.22.0.
Backwards Compatibility Notes
ZstdDecompressor.decompressobj() will change read_across_frames to
default to True in a future release. If you depend on the current
functionality of stopping at frame boundaries, start explicitly passing
read_across_frames=False to preserve the current behavior.
manylinux2010 wheels are no longer published since this wheel format
is no longer supported by the pypa/manylinux project.
Removed CI coverage for PyPy 3.7 and 3.8, which are no longer supported
PyPy versions.
Support for Python 3.7 has been dropped because it reached end of life.
Python 3.8 is the minimum supported Python version. The code should still be
compatible with Python 3.7 and removing of version checks from setup.py
will likely yield a working install. However, this is no officially supported.
Bug Fixes
ZstdDecompressor.decompress() with allow_extra_data=False would
previously allow extra data to exist after an empty zstd frame (a frame
holding 0 length input). This scenario now raises an exception.
Changes
ZstdDecompressor.decompressobj() now accepts a read_across_frames
boolean named argument to control whether to transparently read across
multiple zstd frames. It defaults to False to preserve existing
behavior.
Added CI coverage for PyPy 3.10.
Added CI coverage for newer Anaconda Python versions.
Packages used in CI have been upgraded to latest versions. This should
nominally only impact developers of this project and not end-users.
pyproject.toml now declares a [build-system] section saying to build
with setuptools.
CI now builds wheels with pip instead of setup.py directly.
Official support for CPython 3.12. Binary wheels for 3.12 are now published
during releases. There were no meaningful code changes to support Python 3.12.
Binary wheels for musllinux_1_1 x86_64 and aarch64 are now being built and
published.

Log message: py-zstandard: Bump API depends for zstd to 1.5.5. Doesn't build with 1.5.2. Didn't check 1.5.3 or 1.5.4, since 1.5.5 is what we have in pkgsrc anyway. |

Log message: py-zstandard: updated to 0.20.0 0.20.0 Backwards Compatibility Notes This will likely be the last release officially supporting Python 3.6. Python 3.6 is end of life as of 2021-12-23. Changes 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. |

Log message: py-zstandard: updated to 0.19.0 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. 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. |

Log message: py-zstandard: updated to 0.18.0 0.18.0 Bundled zstd library upgraded from 1.5.1 to 1.5.2. ZstdDecompressionObj now has an unused_data attribute. It will contain data \ beyond the fully decoded zstd frame data if said data exists. ZstdDecompressionObj now has an unconsumed_tail attribute. This attribute \ currently always returns the empty bytes value (b""). ZstdDecompressionObj now has an eof attribute returning whether the compressed \ data has been fully read. |

Log message: py-zstandard: updated to 0.17.0 0.17.0 (released 2021-01-18) Backwards Compatibility Notes ZstdCompressionWriter and ZstdDecompressionWriter now implement __iter__() and \ __next__(). The methods always raise io.UnsupportedOperation. The added methods \ are part of the io.IOBase abstract base class / interface and help ensure \ instances look like other I/O types. The HASHLOG3_MAX constant has been removed since it is no longer defined in zstd \ 1.5.1. Bug Fixes The ZstdCompressionReader, ZstdCompressionWriter, ZstdDecompressionReader, and \ ZstdDecompressionWriter types in the C backend now tracks their closed attribute \ using the proper C type. Before, due to a mismatch between the C struct type and \ the type declared to Python, Python could read the wrong bits on platforms like \ s390x and incorrectly report the value of the closed attribute to Python. Changes Bundled zstd library upgraded from 1.5.0 to 1.5.1. The C backend now exposes the symbols ZstdCompressionReader, \ ZstdCompressionWriter, ZstdDecompressionReader, and ZstdDecompressionWriter. \ This should match the behavior of the CFFI backend. 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. |
