- Update to version 0.20:
* Support for CPython 3.4.
* Support for calling C++ template functions.
* yield is supported in finally clauses.
* The C code generated for finally blocks is duplicated for each exit
case to allow for better optimisations by the C compiler.
* Cython tries to undo the Python optimisationism of assigning a bound
method to a local variable when it can generate better code for the
direct call.
* Constant Python float values are cached.
* String equality comparisons can use faster type specific code in
more cases than before.
* String/Unicode formatting using the '%' operator uses a faster
C-API call.
* bytearray has become a known type and supports coercion from and
to C strings. Indexing, slicing and decoding is optimised. Note that
this may have an impact on existing code due to type inference.
* Using cdef basestring stringvar and function arguments typed as
basestring is now meaningful and allows assigning exactly
str and unicode objects, but no subtypes of these types.
* Support for the __debug__ builtin.
* Assertions in Cython compiled modules are disabled if the running
Python interpreter was started with the "-O" option.
* Some types that Cython provides internally, such as functions and
generators, are now shared across modules if more than one Cython
implemented module is imported.
* The type inference algorithm works more fine granular by taking the
results of the control flow analysis into account.
* A new script in bin/cythonize provides a command line frontend
to the cythonize() compilation function (including distutils build).

- update to 0.19.2:
* Some standard declarations were fixed or updated, including the previously
incorrect declaration of ``PyBuffer_FillInfo()`` and some missing bits in
``libc.math``.
* Heap allocated subtypes of ``type`` used the wrong base type struct at the
C level.
* Calling the unbound method dict.keys/value/items() in dict subtypes could
call the bound object method instead of the unbound supertype method.
* "yield" wasn't supported in "return" value expressions.
* Using the "bint" type in memory views lead to unexpected results.
It is now an error.
* Assignments to global/closure variables could catch them in an illegal state
while deallocating the old value. (forwarded request 204137 from dirkmueller)

OBS-URL: https://build.opensuse.org/package/show/openSUSE:Factory/python-Cython?expand=0&rev=17
- update to 0.19.1:
* Completely empty C-API structs for extension type slots (protocols like
number/mapping/sequence) are no longer generated into the C code.
* Docstrings that directly follow a public/readonly attribute declaration
in a cdef class will be used as docstring of the auto-generated property.
This fixes ticket 206.
* The automatic signature documentation tries to preserve more semantics
of default arguments and argument types. Specifically, ``bint`` arguments
now appear as type ``bool``.
* A warning is emitted when negative literal indices are found inside of
a code section that disables ``wraparound`` handling. This helps with
fixing invalid code that might fail in the face of future compiler
optimisations.
* Constant folding for boolean expressions (and/or) was improved.
* Added a build_dir option to cythonize() which allows one to place
the generated .c files outside the source tree.

* The C-API declarations were updated to include the new
PyDict_*Ref() functions. (Github issue :issue:`7291`)
* Iteration over literal sequences and strings in generators
generated invalid C code since 3.2.0. This was a regression
due to the C array iteration optimisation in :issue:`6926`,
which is now disabled inside of generators. (Github issue
:issue:`7342`)
* Calling special methods of known exception types failed with
an AttributeError. (Github issue :issue:`7342`)
* Calling the unbound __mul__ special method of builtin
collections with subtypes failed. (Github issue
:issue:`7340`)
* C string literals could generate invalid "const to non-const"
casts in the C code. (Github issue :issue:`7346`)
* yield is no longer allowed inside of a
cython.critical_section, but is now allowed while holding a
cython.pymutex. (Github issue :issue:`7317`)
* Under lock congestion, acquiring the GIL could crash in
Python 3.11, part 2. This bug was introduced in Cython 3.2.0.
(Github issue :issue:`7312`)
* The new py_safe_* functions in libc.threads triggered C
compiler warnings. (Github issue :issue:`7356`)
* Cython now leaves markers about its utility code dependencies
in the generated C code to help debugging "unused function" C
compiler warnings. (Github issue :issue:`7294`)
* Relative imports could fail if the shared utility module is
used. This bug was introduced in Cython 3.2.0. (Github issue

- Update to 3.1.4
* Declarations for the new PyUnstable_*() refcounting C-API functions in Py3.14
were added.
* The monitoring code could crash on tracing.
* Initialising the monitoring code could fail with a CPython exception.
* Optimised integer shifting triggered undefined behaviour in C.
* Deallocating objects that inherit from external types defined in pxd files
could run into an infinite loop.
* A reference to metaclasses could be leaked on instantiation.
* (Unlikely) error handling during empty builtin container tests was ineffective.
* Generated *_api.h files used potentially unknown Cython configuration macros.
* cythonize() avoids parallel compiler runs on systems using spawn() in
multiprocessing.
* The @cython.ufunc decorator was missing in type checker stubs.

- Update to 3.1.3
* Some method calls with 0 or 1 argument failed to use PyObject_VectorCallMethod().
* Walrus assignments of literal Python integers could generate invalid C code.
* cython.pythread_type_lock (also used as fallback for cython.pymutex) could stall
on heavily contended locks.
* C string arrays (not pointers) always coerced to the Python default string type,
even on explicit casts to other string types.
* Unterminated \N{} character escapes in strings could unrail the parser.
* An internal C function was not marked as static and leaked a linker symbol.
* Some Unicode letters were not recognised as lexically valid name parts.
* Compatibility with PyPy3.8 was lost by accident.
* The Linux binary wheels of 3.1.2 used SSSE3 CPU instructions which are not
available on some CPUs.

become too long for MSVC.
* The noexcept warnings could be misleading in some cases.
* The @cython.ufunc implementation could generate incomplete C

explicitly with the C macro guard CYTHON_USE_FREELISTS=0.
* Some C macro guards for feature flags were missing from the
NOGIL Python configuration.
* Some recently added builtins were unconditionally looked up
at module import time (if used by user code) that weren't

* A garbage collection enabled subtype of a non-GC extension
type could call into the deallocation function of the
super type with GC tracking enabled. This could lead
to crashes during deallocation if GC was triggered on the
type at the same time.
* Some C compile failures and crashes in CPython 3.12 were
resolved.
* ``except + nogil`` was syntactically not allowed.
* ``except +nogil`` (i.e. defining a C++ exception handling
function called ``nogil``) is now disallowed to prevent typos.
* A C compile failure in PyPy 3.10 was resolved.
* Cython modules now use PEP-489 multi-phase init by default in
PyPy 3.9 and later.
* API header files generated by different Cython versions can
now be included in the same C file.
* Function signatures containing a type like `tuple[()]` could
not be printed.

* 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``.

* 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.

* 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.

C code if the module that imported from them does not use memory views.
* Several declarations in ``libcpp.string`` were added and corrected.
* Pickling unbound Cython compiled methods failed.
* The tracing code was adapted to work with CPython 3.10.
* The optimised ``in`` operator failed on unicode strings in Py3.9 and later
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.
* The attributes ``gen.gi_frame`` and ``coro.cr_frame`` of Cython compiled
generators and coroutines now return an actual frame object for introspection,
instead of ``None``.

* Some problems with Python 3.10 were resolved.
Patches by Victor Stinner and David Woods. (Github issues #4046, #4100)
* An incorrect "optimisation" was removed that allowed changes to a keyword
dict to leak into keyword arguments passed into a function.
Patch by Peng Weikang. (Github issue #3227)
* Multiplied str constants could end up as bytes constants with language_level=2.
Patch by Alphadelta14 and David Woods. (Github issue #3951)

- Update to 0.29.22
* Some declarations were added to the provided pxd includes.
Patches by Zackery Spytz and John Kirkham.
(Github issues #3811, #3882, #3899, #3901)
* A crash when calling certain functions in Py3.9 and later was resolved.
(Github issue #3917)

Patch by Ashwin Srinath. (Github issue #1355)
* The declarations in the ``cpython.pycapsule`` module were missing their
``const`` modifiers and generated incorrect C code.
Patch by Warren Weckesser. (Github issue #3964)
* Casts to memory views failed for fused dtypes.
Patch by David Woods. (Github issue #3881)
* ``repr()`` was assumed to return ``str`` instead of ``unicode``
with ``language_level=3``
* Calling ``cpdef`` functions from cimported modules crashed the compiler.
Patch by David Woods. (Github issue #4000)
* Cython no longer validates the ABI size of the NumPy classes
it compiled against.

(Github issue #2749)
* Coverage reporting in the annotated HTML file failed in Py3.9.
Patch by Nick Pope. (Github issue #3865)
* The embedding code now reports Python errors as exit status.
* Long type declarations could lead to (harmless) random changes in the
C file when used in auto-generated Python wrappers or pickled classes.
