Cython-0.29.33 (Python module)

[Bruce Dubbs]

New point version.

[Bruce Dubbs]

0.29.33 (2023-01-06)

Features added

• The cythonize and cython commands have a new option -M / --depfile to generate .dep dependency files for the compilation unit. This can be used by external build tools to track these dependencies. The cythonize option was already available in Cython :ref:0.29.27.

Bugs fixed

• const fused types could not be used with memory views.
• wstr usage was removed in Python 3.12 and later (PEP-623).
• A type check assertion for Cython functions failed in debug Python builds.
• Fixed various compiler warnings.
• Fixed error when calculating complex powers of negative numbers.
• Corrected a small mis-formatting of exception messages on Python 2.
• The PyUnicode_AsUTF8AndSize() C-API function was missing from the CPython declarations.
• A performance problem in the compiler was resolved when nesting conditional expressions.
• Test suite problems with recent NumPy and CPython versions were resolved.

Other changes

• The undocumented, untested and apparently useless syntax from somemodule cimport class/struct/union somename was deprecated in anticipation of its removal in Cython 3. The type modifier is not needed here and a plain cimport of the name will do.

• Properly disable generation of descriptor docstrings on PyPy since they cause crashes. It was previously disabled, but only accidentally via a typo.

• The cpow directive of Cython 3.0 is available as a no-op.
