* A refence leak of the for-loop list/tuple iterable was
resolved if the for-loop's ``else:`` branch executes
a ``break`` for an outer loop.
* Some C compile failures in CPython 3.12 were resolved.
* Some old usages of the deprecated Python ``imp`` module were
replaced with ``importlib``.
* Patch by Matúš Valo. (Github issue :issue:`5300`)
* Some issues with ``depfile`` generation were resolved.
* Patches by Eli Schwartz. (Github issues :issue:`5279`,
:issue:`5291`)
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python/python-Cython?expand=0&rev=167
* 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.
* ``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.

- update to 0.29.30:
* Avoid acquiring the GIL at the end of nogil functions. This change
was backported in order to avoid generating wrong C code that
would trigger C compiler warnings with tracing support enabled.
* Function definitions in finally: clauses were not correctly generated.
* A case where C-API functions could be called with a live exception
set was fixed.
* Cython now correctly generates Python methods for both the provided
regular and reversed special numeric methods of extension types.
* The C union type in pure Python mode mishandled some field names.

that were constructed from an external ``wchar_t`` source.
Also, related C compiler warnings about deprecated C-API usage were resolved.
* Some compiler crashes were resolved.
* An incorrect warning about 'unused' generator expressions was removed.

- Update to version 0.27
+ Features added
* Extension module initialisation follows
`PEP 489 <https://www.python.org/dev/peps/pep-0489/>`_ in CPython 3.5+, which
resolves several differences with regard to normal Python modules. This makes
the global names ``__file__`` and ``__path__`` correctly available to module
level code and improves the support for module-level relative imports.
(Github issues #1715, #1753, #1035)
* Asynchronous generators (`PEP 525 <https://www.python.org/dev/peps/pep-0525/>`_)
and asynchronous comprehensions (`PEP 530 <https://www.python.org/dev/peps/pep-0530/>`_)
have been implemented. Note that async generators require finalisation support
in order to allow for asynchronous operations during cleanup, which is only
available in CPython 3.6+. All other functionality has been backported as usual.
* Variable annotations are now parsed according to
`PEP 526 <https://www.python.org/dev/peps/pep-0526/>`_. Cython types (e.g.
``cython.int``) are evaluated as C type declarations and everything else as Python
types. This can be disabled with the directive ``annotation_typing=False``.
Note that most complex PEP-484 style annotations are currently ignored. This will
change in future releases. (Github issue #1850)
* Extension types (also in pure Python mode) can implement the normal special methods
``__eq__``, ``__lt__`` etc. for comparisons instead of the low-level ``__richcmp__``
method. (Github issue #690)
* New decorator ``@cython.exceptval(x=None, check=False)`` that makes the signature
declarations ``except x``, ``except? x`` and ``except *`` available to pure Python
code. Original patch by Antonio Cuni. (Github issue #1653)
* Signature annotations are now included in the signature docstring generated by
the ``embedsignature`` directive. Patch by Lisandro Dalcin (Github issue #1781).
* The gdb support for Python code (``libpython.py``) was updated to the latest
version in CPython 3.7 (git rev 5fe59f8).
* The compiler tries to find a usable exception return value for cdef functions
with ``except *`` if the returned type allows it. Note that this feature is subject
to safety limitations, so it is still better to provide an explicit declaration.
* C functions can be assigned to function pointers with a compatible exception
declaration, not only with exact matches. A side-effect is that certain compatible
signature overrides are now allowed and some more mismatches of exception signatures
are now detected and rejected as errors that were not detected before.
* The IPython/Jupyter magic integration has a new option ``%%cython --pgo`` for profile
guided optimisation. It compiles the cell with PGO settings for the C compiler,
executes it to generate a runtime profile, and then compiles it again using that
profile for C compiler optimisation. Currently only tested with gcc.
* ``len(memoryview)`` can be used in nogil sections to get the size of the
first dimension of a memory view (``shape[0]``). (Github issue #1733)
* C++ classes can now contain (properly refcounted) Python objects.
* NumPy dtype subarrays are now accessible through the C-API.
Patch by Gerald Dalley (Github issue #245).
* Resolves several issues with PyPy and uses faster async slots in PyPy3.
Patch by Ronan Lamy (Github issues #1871, #1878).
+ Bugs fixed
* Extension types that were cimported from other Cython modules could disagree
about the order of fused cdef methods in their call table. This could lead
to wrong methods being called and potentially also crashes. The fix required
changes to the ordering of fused methods in the call table, which may break
existing compiled modules that call fused cdef methods across module boundaries,
if these methods were implemented in a different order than they were declared
in the corresponding .pxd file. (Github issue #1873)
* The exception state handling in generators and coroutines could lead to
exceptions in the caller being lost if an exception was raised and handled
inside of the coroutine when yielding. (Github issue #1731)
* Loops over ``range(enum)`` were not converted into C for-loops. Note that it
is still recommended to use an explicit cast to a C integer type in this case.
* Error positions of names (e.g. variables) were incorrectly reported after the
name and not at the beginning of the name.
* Compile time ``DEF`` assignments were evaluated even when they occur inside of
falsy ``IF`` blocks. (Github issue #1796)
* Disabling the line tracing from a trace function could fail.
Original patch by Dmitry Trofimov. (Github issue #1769)
* Several issues with the Pythran integration were resolved.
* abs(signed int) now returns a signed rather than unsigned int.
(Github issue #1837)
* Reading ``frame.f_locals`` of a Cython function (e.g. from a debugger or profiler
could modify the module globals. (Github issue #1836)
* Buffer type mismatches in the NumPy buffer support could leak a reference to the
buffer owner.
* Using the "is_f_contig" and "is_c_contig" memoryview methods together could leave
one of them undeclared. (Github issue #1872)
* Compilation failed if the for-in-range loop target was not a variable but a more
complex expression, e.g. an item assignment. (Github issue #1831)
* Compile time evaluations of (partially) constant f-strings could show incorrect
results.
* Escape sequences in raw f-strings (``fr'...'``) were resolved instead of passing
them through as expected.
* Some ref-counting issues in buffer error handling have been resolved.
+ Other changes
* Type declarations in signature annotations are now parsed according to
`PEP 484 <https://www.python.org/dev/peps/pep-0484/>`_
typing. Only Cython types (e.g. ``cython.int``) and Python builtin types are
currently considered as type declarations. Everything else is ignored, but this
will change in a future Cython release.
(Github issue #1672)
* The directive ``annotation_typing`` is now ``True`` by default, which enables
parsing type declarations from annotations.
* This release no longer supports Python 3.2.
- Update to version 0.26.1
+ Bugs fixed
* ``cython.view.array`` was missing ``.__len__()``.
* Extension types with a ``.pxd`` override for their ``__releasebuffer__`` slot
(e.g. as provided by Cython for the Python ``array.array`` type) could leak
a reference to the buffer owner on release, thus not freeing the memory.

in the generated files despite lying within the project directory.
* Failure to compile in Py3.7 due to a modified signature of ``_PyCFunctionFast()``
- Update to version 0.26
+ Features added
* Pythran can be used as a backend for evaluating NumPy array expressions.
Patch by Adrien Guinet (Github issue #1607).
* cdef classes now support pickling by default when possible.
This can be disabled with the ``auto_pickle`` directive.
* Speed up comparisons of strings if their hash value is available.
Patch by Claudio Freire (Github issue #1571).
* Support pyximport from zip files.
Patch by Sergei Lebedev (Github issue #1485).
* IPython magic now respects the ``__all__`` variable and ignores
names with leading-underscore (like ``import *`` does).
Patch by Syrtis Major (Github issue #1625).
* ``abs()`` is optimised for C complex numbers.
Patch by da-woods (Github issue #1648).
* The display of C lines in Cython tracebacks can now be enabled at runtime
via ``import cython_runtime; cython_runtime.cline_in_traceback=True``.
The default has been changed to False.
* The overhead of calling fused types generic functions was reduced.
* "cdef extern" include files are now also searched relative to the current file.
Patch by Jeroen Demeyer (Github issue #1654).
* Optional optimization for re-aquiring the GIL, controlled by the
`fast_gil` directive.
+ Bugs fixed
* Item lookup/assignment with a unicode character as index that is typed
(explicitly or implicitly) as ``Py_UCS4`` or ``Py_UNICODE`` used the
integer value instead of the Unicode string value. Code that relied on
the previous behaviour now triggers a warning that can be disabled by
applying an explicit cast. (Github issue #1602)
* f-string processing was adapted to changes in PEP 498 and CPython 3.6.
* Invalid C code when decoding from UTF-16(LE/BE) byte strings.
(Github issue #1696)
* Unicode escapes in 'ur' raw-unicode strings were not resolved in Py2 code.
Original patch by Aaron Gallagher (Github issue #1594).
* File paths of code objects are now relative.
Original patch by Jelmer Vernooij (Github issue #1565).
* Decorators of cdef class methods could be executed twice.
Patch by Jeroen Demeyer (Github issue #1724).
* Dict iteration using the Py2 ``iter*`` methods failed in PyPy3.
Patch by Armin Rigo (Github issue #1631).
* Several warnings in the generated code are now suppressed.
+ Other changes
* The ``unraisable_tracebacks`` option now defaults to ``True``.
* Coercion of C++ containers to Python is no longer automatic on attribute
access (Github issue #1521).
* Access to Python attributes of cimported modules without the corresponding
import is now a compile-time (rather than runtime) error.
* Do not use special dll linkage for "cdef public" functions.
Patch by Jeroen Demeyer (Github issue #1687).
* cdef/cpdef methods must match their declarations. See Github Issue #1732.
This is now a warning and will be an error in future releases.
- Update to version 0.25.2
+ Bugs fixed
* Fixes several issues with C++ template deduction.
* Fixes a issue with bound method type inference (Github issue #551).
* Fixes a bug with cascaded tuple assignment (Github issue #1523).
* Fixed or silenced many Clang warnings.
* Fixes bug with powers of pure real complex numbers (Github issue #1538).
