./lang/py-cython, C-Extensions for Python

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 3.1.2, Package name: py312-cython-3.1.2, Maintainer: pkgsrc-users

The Cython language makes writing C extensions for the Python language
as easy as Python itself. Cython is a source code translator based on
the well-known Pyrex, but supports more cutting edge functionality and
optimizations.

The Cython language is very close to the Python language (and most
Python code is also valid Cython code), but Cython additionally supports
calling C functions and declaring C types on variables and class
attributes. This allows the compiler to generate very efficient C code
from Cython code.

This makes Cython the ideal language for writing glue code for external
C libraries, and for fast C modules that speed up the execution of
Python code.

py-cython: updated to 3.1.2

3.1.2 (2025-06-09)

Bugs fixed

* Attribute lookups failed on the ``bool`` builtin type.
* Type checks on or-ed union types could incorrectly return false.
* Negative list indexing could accidentally wrap around twice in PyPy and the \ 
Limited API.
* Iterating over literal sequences with starred (unpacked) items could infer a wrong
  type for the loop variable and fail to assign the values.
* Calls to C functions taking exception types failed to check for a `None` argument.
* Fused functions had an incorrect ``__module__`` attribute.
* The type of Cython implemented functions had an incorrect ``__module__`` attribute.
* Errors while indexing into ``bytearray`` or ``str`` in ``nogil`` sections \ 
could crash.
* ``bytearray.append()`` could silently accept some invalid character numbers.
* The C++11 ``<type_traits>`` header was included regardless of the C++ \ 
version.
* ``PyDict_GetItemStringRef()`` was accidentally used in older Limited API versions.
* ``abort()`` was used but not always available in the Limited API.
* Some dependencies were missing from the ``depfile``.
* Embedded function signatures were not always separated from the existing docstring.
* ``numpy.math`` was missing from ``Cython/Includes/`` and could not be cimported.
* Some tests were adapted for NumPy 2.x.
* Some C compiler warnings were fixed.
* ``Cython.Build`` was not officially exposing the ``cythonize`` function.

py-cython: updated to 3.1.1

3.1.1 (2025-05-19)

Bugs fixed

* A reference leak in the async delegation code was fixed.
* Conditional if-else expressions mixing Python and C (numeric) types could end up
  inferring an overly tight result type, thus leading to unexpected type conversions,
  runtime exceptions on assignment, or incorrect "temporary \ 
assignment" compile errors.
* Some Limited API issues were resolved.
* Large C ``long long`` values could be truncated when passed into PyPy.
* ``callable()`` incorrectly reported ``False`` in PyPy for classes with metaclasses.
* The signature of fused functions was no longer introspectable in Cython 3.1.0.
* Coroutines could generate invalid C with line tracing enabled.
* Code using ``complex()`` could generate invalid C code missing type declarations.
* Code using e.g. ``list[int | None]``  outside of variable/argument annotations \ 
failed to compile.
* Code using ctuples in a ``const`` context could generate invalid C.
* Accessing special methods on cpdef enums failed to compile.
* Some C compiler warnings were resolved.
* Re-establish support for PyPy 3.8.

Log message:
py-cython: update to 3.1.0.

3.1.0 (2025-05-08)
==================

Other changes
-------------

* No functional changes since 3.1.0 rc 2.

3.1.0 rc 2 (2025-05-07)
=======================

Features added
--------------

* Declarations for C++ ``std::stop_token`` were added as ``libcpp.stop_token`` \ 
to provide
  additional low-level synchronisation primitives also in the light of \ 
free-threading Python.
  (Github issue :issue:`6820`)

* The generation of the shared module now happens automatically from \ 
``cythonize()`` in a
  ``setuptools`` build if a corresponding ``Extension`` has been configured.
  This avoids an additional step outside of the ``setup.py`` or ``pip wheel`` run.
  (Github issue :issue:`6842`)

Bugs fixed
----------

* Variables typed as builtin Python exception types now accept subtypes instead \ 
of rejecting them.
  This specifically impacted types like ``BaseException``, ``Exception`` or \ 
``OSError``,
  which almost always intend to reference subtypes.
  (Github issue :issue:`6828`)

* Functions with more than 10 constant default argument values could generate \ 
invalid C code.
  (Github issue :issue:`6843`)

* The ``call_once()`` function argument in ``libc.threads`` (new in 3.1) was \ 
changed to require
  a ``nogil`` declaration, as semantically implied.  Code that used it with a \ 
callback function
  expecting to hold the GIL must change the callback code to use ``with gil``.

* Calling cimported C functions with their fully qualified package name could \ 
crash Cython.
  (Github issue :issue:`6551`)

* Naming a variable after its inferred type (e.g. `str += ""`) could \ 
trigger an infinite loop in Cython.
  (Github issue :issue:`6835`)

* Cython is more relaxed about the exact C++ constructor name when it calls \ 
``new()`` on ctypedefs.
  (Github issue :issue:`6821`)

* Using ``cpp_locals`` in nogil sections could crash.
  (Github issue :issue:`6838`)

* ``const struct`` declarations could lead to invalid assignments to ``const`` \ 
temp variables.
  (Github issue :issue:`6804`)

* A refcounting error was fixed in the method class cell support code.
  (Github issue :issue:`6839`)

3.1.0 rc 1 (2025-05-01)
=======================

Features added
--------------

* ``cython.pymutex`` provides a fast mutex by wrapping the new ``PyMutex`` \ 
feature of recent
  CPython versions (including free-threading) and falls back to ``PyThread`` \ 
locks in older Pythons.
  (Github issue :issue:`6579`)

* A new directive ``subinterpreters_compatible=shared_gil/own_gil`` was added to \ 
allow modules
  to declare support for subinterpreters.
  (Github issue :issue:`6513`)

* ``divmod()`` is also optimised for C floating point types and can be called on \ 
C number types
  without holding the GIL.
  (Github issue :issue:`6801`)

* New C++ declarations were added.
  (Github issues :issue:`6625`, :issue:`6731`)

* ``embedsignature`` now works for special methods (if they have a docstring).
  (Github issue :issue:`1577`)

Bugs fixed
----------

* Iterating over literal sequences in generator expressions could generate \ 
invalid C code.
  (Github issue :issue:`6725`)

* Tracing could generate invalid C code.
  (Github issue :issue:`6781`)

* Non-ASCII function argument names could generate invalid C code.
  (Github issue :issue:`6813`)

* Optimised ``divmod()`` calls could produce incorrect results in beta-1 due to \ 
incorrect C type usage.
  (Github issue :issue:`6786`)

* Raising ``UnboundLocalError`` could fail for non-ascii variable names.
  (Github issue :issue:`6800`)

* The signature of ``PyByteArray_Resize()`` in ``cpython.bytearray`` failed to \ 
propagate exceptions.
  Patch by Kirill Smelkov.  (Github issue :issue:`6787`)

* Some more issues with the Limited C-API and free-threading Python were resolved.

  https://github.com/cython/cython/issues?q=label%3A%22limited+api%22

  https://github.com/cython/cython/issues?q=label%3A%22nogil+CPython%22

* The signature of ``cythonize_one()`` accidentally changed in 3.1.0b1.
  (Github issue :issue:`6815`)

Other changes
-------------

* Named ``cpdef enums`` no longer copy their item names into the global module \ 
namespace.
  This was considered unhelpful for named enums which already live in their own \ 
class namespace.
  In cases where the old behaviour was desired, users can add the following \ 
backwards compatible
  command after their enum class definition: \ 
``globals().update(TheUserEnumClass.__members__)``.
  Anonymous enums still produce global item names, as before.
  (Github issue :issue:`4571`)

3.1.0 beta 1 (2025-04-03)
==========================

Features added
--------------

* Global ``cdef const …`` variables are supported.
  (Github issue :issue:`6542`)

* A new context manager / function decorator ``cython.critical_section`` was added
  wrapping Python's critical section C-API feature.
  (Github issues :issue:`6516`, :issue:`6577`)

* Some common Cython-internal code (currently only memoryview related) can now \ 
be extracted
  into a shared extension module to reduce the installed overall size of a \ 
package with many
  Cython compiled modules.
  (Github issue :issue:`2356`)

* The type of ``prange`` loop targets is now inferred.
  (Github issue :issue:`6585`)

* Extracting keyword arguments is faster in some cases.
  (Github issue :issue:`6683`)

* Calling ``divmod()`` on any C integer types is efficient.
  (Github issue :issue:`6717`)

* Some async/coroutine/vectorcall code has improved fast-paths.
  (Github issues :issue:`6732`, :issue:`6735`, :issue:`6736`, :issue:`6738`, \ 
:issue:`6742`, :issue:`6771`)

* Calls to Python builtins and extension types use the vectorcall protocol.
  (Github issue :issue:`6744`)

* Method calls use ``PyObject_VectorcallMethod()`` where possible.
  (Github issue :issue:`6747`)

* Some C-API shortcuts were (re-)added.
  (Github issue :issue:`6761`)

* Cython can avoid normalising exceptions in an `except` clause if it knows that \ 
they are unused.
  (Github issue :issue:`6601`)

* The ``cython`` command has a new option ``--cache`` to cache generated files.
  (Github issue :issue:`6091`)

* The ``cythonize`` command has a new option ``--timeit`` to benchmark Cython \ 
code snippets.
  (Github issue :issue:`6697`)

* The argument parsing ``cygdb`` command was improved based on ``argparse``.
  Patch by William Ayd.  (Github issue :issue:`5499`)

* The ``PyWeakref_GetRef`` declaration was added to ``cpython.weakref`` and \ 
backported.
  Patch by Lysandros Nikolaou.  (Github issue :issue:`6478`)

* ``std::span`` declarations were added to ``libcpp``.
  Patch by Alexander Condello.  (Github issue :issue:`6539`)

* ``std::string_view`` declarations were added to ``libcpp``.
  Patch by Antoine Pitrou.  (Github issue :issue:`6539`)

* Mutex declarations for ``libc`` and  ``libcpp`` were added.
  (Github issue :issue:`6610`)

* Several C++ declarations were improved and extended.
  Patches by Yury V. Zaytsev.  (Github issues :issue:`488`, :issue:`489`)

* Bazel build rules were updated for better interoperability.
  Patch by maleo.  (Github issue :issue:`6478`)

* The ``Demos/benchmarks/`` directory include a new benchmark runner that can \ 
run selected
  benchmarks against different Cython git revisions.

Bugs fixed
----------

* Many issues with the Limited C-API and free-threading Python were resolved.
  This includes better thread-safety of Cython-internal types like functions and \ 
generators.

  https://github.com/cython/cython/issues?q=label%3A%22nogil+CPython%22

* ``for-in`` loops could generate invalid code for C++ containers.
  Patch by Taras Kozlov.  (Github issue :issue:`6578`)

* ``PyDict_GetItemRef()`` and ``PyList_GetItemRef()`` were not always used correctly.
  Patch by Lisandro Dalcin.  (Github issue :issue:`6647`)

* Inlined calls to local functions could crash with ``binding=False``.
  (Github issue :issue:`6556`)

* Calling ``sorted()`` could crash in 3.1.0a1.
  (Github issue :issue:`6496`)

* Calling 0-arg methods was unnecessarily slow in 3.1.0a1.
  (Github issue :issue:`6730`)

* A crash when reading the interpreter ID was fixed.

  (Github issue :issue:`6503`)

* A compiler crash on ``complex/complex`` was resolved.
  (Github issue :issue:`6552`)

* A compiler crash when using the ``cpp_locals`` directive was resolved.
  (Github issue :issue:`6370`)

* Name mangling did not work correctly for attributes of extension types that \ 
have reserved C names.
  (Github issue :issue:`6678`)

* Declaring a ``@staticmethod`` in a pxd file and overriding it in a subclass could
  trigger incorrect "declared but not defined" errors.
  Patch by Aditya Pillai.  (Github issue :issue:`6714`)

* Cython's fake code objects are now compatible with GraalPython.
  (Github issue :issue:`6409`)

* Stepping through foreign code with ``cygdb`` could fail with an ``IndexError``.
  Patch by clayote.  (Github issue :issue:`6552`)

* Some PyPy incompatibilities were resolved.
  Patches by Matti Picus.  (Github issue :issue:`6592`,  :issue:`6640`)

* Interoperability with recent Pythran releases was fixed.
  (Github issue :issue:`6494`)

* The ``gdb`` compatibility of ``cygdb`` was improved.

removed again.
  (Github issue :issue:`6671`)

* Using the ``common_utility_include_dir`` option in parallel builds on Windows \ 
could fail.

* Some "unused" warnings from the C compiler were resolved.
  Patches by Lisandro Dalcin.  (Github issue :issue:`6726`)

Other changes
-------------

* All Cython-internal types (functions, coroutines, …) are now heap types and \ 
use type specs.
  (Github issue :issue:`6633`)

* Tracing/monitoring is now disabled in parallel/prange sections.
  (Github issue :issue:`6709`)

* The ``numpy.math`` cimport module has been deprecated.
  Usages should be replaced by ``libc.math``.
  (Github issue :issue:`6743`)

* Includes all fixes as of Cython 3.0.12.

3.1.0 alpha 1 (2024-11-08)
==========================

Features added
--------------

* Support for freethreading builds of CPython 3.13 was added.
  It comes with a new directive ``freethreading_compatible=True`` to mark modules as
  free-threading compatible (``Py_mod_gil``).

  https://github.com/cython/cython/issues?q=label%3A%22nogil+CPython%22

  Patches by Lysandros Nikolaou and Nathan Goldbaum.  (Github issue :issue:`6162`)

* Support for monitoring Cython modules via `sys.monitoring` in CPython 3.13+ \ 
was added.
  For coverage reporting, this needs to be disabled with \ 
`-DCYTHON_USE_SYS_MONITORING=0`
  as long as `coverage.py` does not support `sys.monitoring` for coverage plugins.
  (Github issue :issue:`6144`)

* Many issues with the Limited C-API were resolved.
  It is now sufficient to define the macro ``Py_LIMITED_API`` to activate the \ 
support.

  https://github.com/cython/cython/issues?q=label%3A%22limited+api%22

* Support for GraalPython was improved (but is still incomplete).

* Several issues with the gdb support were resolved.
  Patches by Kent Slaney.  (Github issues :issue:`5955`, :issue:`5948`)

* ``typing.Union[SomeType, None]`` and ``SomeType | None`` are now understood \ 
and mean
  the same as ``typing.Optional[SomeType]``, allowing ``None`` in type checks.
  (Github issue :issue:`6254`)

* ``cython.const[]`` and ``cython.volatile[]`` are now available as type \ 
modifiers in Python code.
  (Github issue :issue:`5728`)

* ``cython.pointer[SomeCType]`` can now be used to define pointer types in \ 
Python type annotations.
  (Github issue :issue:`5071`)

* Several improvements were made to reduce the size of the resulting extension \ 
modules.
  (Github issue :issue:`4425`)

* Function calls now use the PEP-590 Vectorcall protocol, even when passing \ 
keyword arguments.
  (Github issues :issue:`5804`)

* Coroutines now use the ``am_send`` slot function instead of going through a \ 
Python ``.send()`` call.
  This has been backported for Python 3.7 - 3.9.
  (Github issues :issue:`4585`)

* ``__set_name__`` is called when assigning to class attributes.
  (Github issue :issue:`6179`)

* Most builtin methods now provide their return type for type inference.
  (Github issues :issue:`4829`, :issue:`5865`, :issue:`6412`)

* Method calls on builtin literal values are evaluated at compile time, if \ 
applicable.
  (Github issue :issue:`6383`)

* The Python ``int`` type now maps directly to ``PyLong`` and is inferred \ 
accordingly.
  (Github issue :issue:`4237`)

* Integer operations on known ``int`` types are faster.
  (Github issue :issue:`5785`)

* f-strings are faster in some cases.
  (Github issues :issue:`5866`, :issue:`6342`, :issue:`6383`)

* ``divmod()`` is faster on C ``int``.
  Patch by Tong He.  (Github issue :issue:`6073`)

* ``dict.pop()`` is faster in some cases.
  (Github issue :issue:`5911`)

* ``.isprintable()`` is optimised for Unicode characters.
  (Github issue :issue:`3277`)

* ``x in ()`` and similar tests against empty constant sequences (e.g. in \ 
generated code)
  are now discarded if they have no side-effects.
  (Github issue :issue:`6288`)

* Constant (non-GC) Python objects are no longer traversed with ``Py_VISIT()`` \ 
during GC runs.
  (Github issue :issue:`6277`)

* C++ classes implemented in Cython can now use method overloading.
  Patch by samaingw.  (Github issue :issue:`3235`)

* Assigning a Python container to a C++ vector now makes use of ``__length_hint__``
  to avoid reallocations.
  Patch by Denis Lukianov.  (Github issue :issue:`6077`)

* The C++11 ``emplace*`` methods were added to ``libcpp.deque``.
  Patch by Somin An.  (Github issue :issue:`6159`)

* ``cpython.time`` was updated and extended for Python 3.13.
  (Github issue :issue:`6187`)

* Dataclasses support the ``match_args`` option.
  (Github issue :issue:`5381`)

* Threading in parallel sections can now be disabled with a new \ 
``use_threads_if`` condition.
  (Github issue :issue:`5919`)

* New options ``warn.deprecated.DEF`` and ``warn.deprecated.IF`` can silence the \ 
deprecation warnings.
  Patch by Eric Larson.  (Github issue :issue:`6243`)

* ``cygdb`` shows more helpful output for some objects.
  Patch by Kent Slaney.  (Github issue :issue:`5958`)

* Bazel build support for improved.
  Patch by mering.  (Github issue :issue:`6452`)

* The parser was updated for Unicode 15.1 (as provided by CPython 3.13b4).

Bugs fixed
----------

* C functions used different start lines and columns for error reporting and tracing
  than Python functions.  They now use the line and column of their first decorator
  or (if none) their definition line, as in Python.
  (Github issue :issue:`6366`)

* Dataclasses did not handle default fields without init value correctly.
  (Github issue :issue:`5858`)

* Implementing a special method based on another could lead to infinite recursion.
  (Github issue :issue:`5863`)

* The ``__class__`` cell variable in methods was not always working as in Python.
  Initial patch by Tom Keefe.  (Github issue :issue:`2912`)

* Lambda functions had no code objects. Their signature can now be introspected.
  (Github issue :issue:`2983`)

* Subtyping `complex` as extension type could fail.
  (Github issue :issue:`6346`)

* ``hasattr()`` now propagates exceptions that occur during lookup.
  (Github issue :issue:`6269`)

* The base type of extension heap types is now traversed during GC runs in Py3.9+.
  (Github issue :issue:`4193`)

* The Python ``&`` operator could touch invalid memory with certain ``0`` \ 
values in Python <= 3.10.
  Patch by Michael J. Sullivan.  (Github issue :issue:`4193`)

* Exception values were not always recognised as equal at compile time.
  (Github issue :issue:`5709`)

* Running Cython in different Python versions could generate slightly different \ 
C code
  due to differences in the builtins.
  (Github issue :issue:`5591`)

* The `common_include_dir` feature used different file paths in the C code on \ 
Windows and Posix.
  It now uses forward slashes as directory separator consistently.
  (Github issue :issue:`6355`)

* File paths in the C code are now relative to the build directory.
  Patch by Oscar Benjamin.  (Github issue :issue:`6341`)

* depfiles now use relative paths whenever possible.
  Patch by Loïc Estève.  (Github issue :issue:`6345`)

* The ``-a`` option in the IPython magic no longer copies the complete HTML document
  into the notebook but only a more reasonable content snippet.
  Patch by Min RK.  (Github issue :issue:`5760`)

* Uselessly referring to C enums (not enum values) as Python objects is now rejected.
  Patch by Vyas Ramasubramani.  (Github issue :issue:`5638`)

* Cython no longer acquires the GIL during in-place assignments to C attributes \ 
in nogil sections.
  Patch by Mads Ynddal.  (Github issue :issue:`6407`)

* Several C++ warnings about ``char*`` casts were resolved.
  (Github issues :issue:`5515`, :issue:`5847`)

* C++ undefined behaviour was fixed in an error handling case.
  (Github issue :issue:`5278`)

* Dict assignments to struct members with reserved C/C++ names could generate \ 
invalid C code.

* The PEP-479 implementation could raise a visible ``RuntimeError`` without
  a trace of the original ``StopIteration``.
  (Github issue :issue:`5953`)

* A crash was fixed when assigning a zero-length slice to a memoryview.
  Patch by Michael Man.  (Github issue :issue:`6227`)

* Conditionally assigning to variables with the walrus operator could crash.
  (Github issue :issue:`6094`)

* Unterminated string literals could lock up the build in an infinite loop.
  (Github issue :issue:`5977`)

* Exporting C functions uses better platform compatible code.
  (Github issue :issue:`4683`)

* The shebang in ``libpython.py`` was incorrect.
  Patch by Luke Hamburg.  (Github issue :issue:`6439`)

* Cython now uses `SHA-256` instead of `SHA-1` for caching etc. as the latter \ 
may not be
  available on all Python installations.
  (Github issue :issue:`6354`)

Other changes
-------------

* Support for Python 2.7 - 3.7 was removed, along with large chunks of legacy code.
  (Github issue :issue:`2800`)

* The pxd files ``cpython.int``, ``cpython.cobject``, ``cpython.oldbuffer`` and \ 
``cpython.string``
  were removed as they refer to C-API declarations that are only in Python 2.x.
  (Github issue :issue:`5870`)

* The generated C code now requires a C99 compatible C compiler.

* ``language_level=3`` is now the default.
  ``language_level=3str`` has become a legacy alias.
  (Github issue :issue:`5827`)

* The Py2 types ``unicode`` and ``basestring`` are now deprecated and have \ 
become aliases
  of the ``str`` type.
  (Github issue :issue:`6374`)

* Docstrings now strip their leading whitespace according to PEP-257.
  Patch by Lawrence Mitchell.  (Github issue :issue:`6241`)

* Type checkers should have it easier to find and validate Cython types in .py files.
  (Github issue :issue:`4327`)

* The previously shipped NumPy C-API declarations (``cimport numpy``) were removed.
  NumPy has been providing version specific declarations for several versions now.
  (Github issue :issue:`5842`)

* Usages of the outdated ``WITH_THREAD`` macro guard were removed.
  (Github issue :issue:`5812`)

* The options for showing the C code line in Python exception stack traces were \ 
cleaned up.
  Previously, disabling the option with the ``CYTHON_CLINE_IN_TRACEBACK`` macro \ 
did not
  reduce the code overhead of the feature, and the ``c_line_in_traceback`` \ 
compile option
  was partly redundant with the C macro switches and lead to warnings about \ 
unused code.
  Since this is considered mostly a debug feature, the new default is that it is \ 
_disabled_
  to avoid code and runtime overhead.  It can be enabled by setting the C macro \ 
to 1, and
  a new macro ``CYTHON_CLINE_IN_TRACEBACK_RUNTIME`` was added that controls the \ 
runtime
  configurable setting if the feature is enabled, which was previously only available
  through the compile option.  The compile option is now deprecated (but still \ 
available),
  and users should migrate to using the two C macros only.
  (Github issue :issue:`6036`)

* Includes all fixes as of Cython 3.0.11 (but generates C99 code in some places).

lang/python and a number of python packages: re-do atomic64.mk issue.

Evidently, python 3.13 brought in the need to support 64-bit atomics.
This means that python extension packages built with C needs to
use mk/atomic64.mk to make -latomic available on the required 32-bit
ports.  Sadly, there is no reliable way to detect in the .mk files
whether the package is using C (or C++), so this change adds an
unconditional include of mk/atomic64.mk when the python version is
equal to or larger than 3.13 for packages using egg.mk or wheel.mk.

This undoes the individual package Makefile inclusions of mk/atomic64.mk
that I've added over the last few days.
