- add sle15_python_module_pythons (jsc#PED-68)

- Update to 3.0.0~b2
  # Features added
  * C++ declarations for <cmath>, <numbers> and std::any were
    added. Patches by Jonathan Helgert and Maximilien Colange.
    (Github issues #5262, #5309, #5314)
  # Bugs fixed
  * Unintended internal exception handling lead to a visible
    performance regression for nogil memoryview code in 3.0.0b1.
    (Github issue #5324)
  * None default arguments for arguments with fused memoryview
    types could select a different implementation in 3.0 than in
    0.29.x. The selection behaviour is generally considered
    suboptimal but was at least reverted to the old behaviour for
    now. (Github issue #5297)
  * The new complex vs. floating point behaviour of the ** power
    operator accidentally added a dependency on the GIL, which was
    really only required on failures. (Github issue #5287)

    being found in annotations. Patch by Chia-Hsiang Cheng. (Github
    issue #5235)
  * Generated NumPy ufuncs could crash for large arrays due to
    incorrect GIL handling. (Github issue #5328)

- Release 3.0.0~b1
# Features added
* Cython implemented C functions now propagate exceptions by
default, rather than swallowing them in non-object returning
function if the user forgot to add an except declaration to the
signature. This was a long-standing source of bugs, but can
require adding the noexcept declaration to existing functions
if exception propagation is really undesired. (Github issue
#4280)
* To opt out of the new, safer exception handling behaviour,
legacy code can set the new directive
legacy_implicit_noexcept=True for a transition period to keep
the previous, unsafe behaviour. This directive will eventually
be removed in a later release. Patch by Matúš Valo. (Github
issue #5094)
* A new function decorator @cython.ufunc automatically generates
a (NumPy) ufunc that applies the calculation function to an
entire memoryview. (Github issue #4758)
* The ** power operator now behaves more like in Python by
returning the correct complex result if required by math. A new
cpow directive was added to turn on the previous C-like
behaviour. (Github issue #4936)
* The special __*pow__ methods now support the 2- and 3-argument
variants. (Github issue #5160)
* Unknown type annotations (e.g. because of typos) now emit a
warning at compile time. Patch by Matúš Valo. (Github issue
#5070)
* Subscripted builtin types in type declarations (like
list[float]) are now better supported. (Github issue #5058)
* Python’s memoryview is now a known builtin type with optimised
properties. (Github issue #3798)
* The call-time dispatch for fused memoryview types is less slow.
(Github issue #5073)
* Integer comparisons avoid Python coercions if possible. (Github
issue #4821)
* The Python Enum of a cpdef enum now inherits from IntFlag to
better match both Python and C semantics of enums. (Github
issue #2732)
* PEP-614: decorators can now be arbitrary Python expressions.
(Github issue #4570)
* cpdef enums can now be pickled. (Github issue #5120)
* Bound C methods can now coerce to Python objects. (Github
issues #4890, #5062)
* C arrays can be initialised inside of nogil functions. Patch by
Matúš Valo. (Github issue #1662)
* reversed() can now be used together with C++ iteration. Patch
by Chia-Hsiang Cheng. (Github issue #5002)
* Standard C/C++ atomic operations are now used for memory views,
if available. (Github issue #4925)
* C11 complex.h is now properly detected. (Github issue #2513)
* Nested cppclass definitions are supported. Patch by samaingw.
(Github issue #1218)
* cpp_locals no longer have to be “assignable”. (Github issue
#4558)
* cythonize --help now also prints information about the
supported environment variables. Patch by Matúš Valo. (Github
issue #1711)
* Declarations were added for the C++ bit operations, some other
parts of C++20 and CPython APIs. Patches by Jonathan Helgert,
Dobatymo, William Ayd and Max Bachmann. (Github issues #4962,
#5101, #5157, #5163, #5257)
# Bugs fixed
* Generator expressions and comprehensions now look up their
outer-most iterable on creation, as Python does, and not later
on start, as they did previously. (Github issue #1159)
* Type annotations for Python int rejected long under Py2 in the
alpha-11 release. They are now ignored again (as always before)
when language_level=2, and accept both int and long in Py2 (and
only int in Py3) otherwise. (Github * issue #4944)
* Calling bound classmethods of builtin types could fail trying
to call the unbound method. (Github issue #5051)
* int(Py_UCS4) returned the code point instead of the parsed
digit value. (Github issue #5216)
* Several problems with CPython 3.12 were resolved. (Github issue
#5238)
* The C float type was not inferred on assignments. (Github issue
#5234)
* Memoryviews with object item type were not supported in Python
type declarations. (Github issue #4907)
* Iterating over memoryviews in generator expressions could leak
a buffer reference. (Github issue #4968)
* Memory views and the internal Cython array type now identify as
collections.abc.Sequence by setting the Py_TPFLAGS_SEQUENCE
type flag directly. (Github issue #5187)
* __del__ finaliser methods were not always called if they were
only inherited. (Github issue #4995)
* Extension types are now explicitly marked as immutable types to
prevent them from being considered mutable. Patch by Max
Bachmann. (Github issue #5023)
* const types could not be returned from functions. Patch by Mike
Graham. (Github issue #5135)
* cdef public functions declared in .pxd files could use an
incorrectly mangled C name. Patch by EpigeneMax. (Github issue
#2940)
* cdef public functions used an incorrect linkage declaration in
C++. Patch by Maximilien Colange. (Github issue #1839)
* C++ post-increment/-decrement operators were not correctly
looked up on declared C++ classes, thus allowing Cython
declarations to be missing for them and incorrect C++ code to
be generated. Patch by Max Bachmann. (Github issue * #4536)
* C++ iteration more safely stores the iterable in temporary
variables. Patch by Xavier. (Github issue #3828)
* C++ references did not work on fused types. (Github issue
#4717)
* The module state struct was not initialised in correct C
(before C23), leading to compile errors on Windows. Patch by
yudonglin. (Github issue #5169)
* Structs that contained an array field resulted in incorrect C
code. Their initialisation now uses memcpy(). Patch by
Chia-Hsiang Cheng. (Github issue #5178)
* Nesting fused types in other fused types could fail to
specialise the inner type. (Github issue #4725)
* The special methods __matmul__, __truediv__, __floordiv__
failed to type their self argument. (Github issue #5067)
* Coverage analysis failed in projects with a separate source
subdirectory. Patch by Sviatoslav Sydorenko and Ruben
Vorderman. (Github issue #3636)
* The annotation_typing directive was missing in pure Python
mode. Patch by 0dminnimda. (Github issue #5194)
* The @dataclass directive was accidentally inherited by methods
and subclasses. (Github issue #4953)
* Some issues with Cython @dataclass arguments, hashing,
inheritance and repr() were resolved. (Github issues #4956,
#5046)
* cpdef enums no longer use OrderedDict but dict in Python 3.6
and later. Patch by GalaxySnail. (Github issue #5180)
* Larger numbers of extension types with multiple subclasses
could take very long to compile. Patch by Scott Wolchok.
(Github issue #5139)
* Relative imports failed in compiled __init__.py package
modules. Patch by Matúš Valo. (Github issue #3442)
* Some old usages of the deprecated Python imp module were
replaced with importlib. Patch by Matúš Valo. (Github issue
#4640)
* The cython and cythonize commands ignored non-existing input
files without error. Patch by Matúš Valo. (Github issue #4629)
* Invalid and misspelled cython.* module names were not reported
as errors. (Github issue #4947)
* Unused **kwargs arguments did not show up in locals(). (Github
issue #4899)
* Extended glob paths with /**/ and \**\ for finding source files
failed on Windows.
* Annotated HTML generation was missing newlines in 3.0.0a11.
(Github issue #4945)
* Some parser issues were resolved. (Github issue #4992)
* setup.cfg was missing from the source distribution. (Github
issue #5199)
* Some C/C++ warnings were resolved. Patches by Max Bachmann,
Alexander Shadchin, at al. (Github issues #5004, #5005, #5019,
#5029, #5096)
* The embedding code no longer calls deprecated C-API functions
but uses the new PyConfig API instead on CPython versions that
support it (3.8+). Patch by Alexander Shadchin. (Github issue
#4895)
* Intel C compilers could complain about unsupported gcc pragmas.
Patch by Ralf Gommers. (Github issue #5052)
* Includes all bug-fixes and features from the 0.29 maintenance
branch up to the 0.29.33 (2023-01-06) release.
# Other changes
* The undocumented, untested and apparently useless syntax from
somemodule cimport class/struct/union somename was removed. The
type modifier is not needed here and a plain cimport of the
name will do. (Github issue #4904)
* C-style array declarations (cdef int a[4]) are now (silently)
deprecated in favour of the Java-style cdef int[4] a form. The
latter was always available and the Python type declaration
syntax already used it exclusively (a: int[4]).Patch by Matúš
Valo. (Github issue #5248)
* The wheel building process was migrated to use the cibuildwheel
tool. Patch by Thomas Li. (Github issue #4736)
* Wheels now include a compiled parser again, which increases
their size a little but gives about a 10% speed-up when running
Cython.
* The Tempita module no longer contains HTML processing
capabilities, which were found to be broken in Python 3.8 and
later. Patch by Marcel Stimberg. (Github issue #3309)
* The Emacs Cython mode file cython-mode.el is now maintained in
* a separate repo: https://github.com/cython/emacs-cython-mode
Cython now uses a .dev0 version suffix for unreleased source
installations.
