Forwarded request #1299226 from mcalabkova

- 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.
  - Convert to libalternatives on SLE-16-based and newer systems only

- update to 3.2.2:
* 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
:issue:`7290`)
* Under lock congestion, acquiring the GIL could crash in
Python 3.11. This bug was introduced in Cython 3.2.0. (Github
issue :issue:`7312`)
* Using the shared utility module left an unused C function in
user modules with memoryviews. To make debugging this kind of
issue easier, Cython now leaves "used by …" markers in the
generated C files that indicate why a specific piece of
utility code was included. This bug was introduced in Cython
3.2.0. (Github issue :issue:`7293`)
* Code using the pre-import scope failed with an undefined
name. This bug was introduced in Cython 3.2.0. (Github issue
:issue:`7304`)
* Includes all fixes as of Cython 3.1.7.
* Builtin exception types are now inferred. (Github issue
:issue:`6908`)
* The list of known, inferred and optimised Python builtins was
updated. range is now considered a type. ascii, bin, format,
hex, oct were added as functions. (Github issue
:issue:`6931`)
* The f-string syntax was extended according to PEP-701.
(Github issue :issue:`5452`)
* t-strings are implemented according to PEP-750. The
implementation backports the template classes but prefers
existing backports if installed separately. (Github issue
:issue:`6811`)
* Unknown return type annotations with -> are no longer
rejected but produce warnings. This allows better integration
with Python type hints that are not always usable for Cython.
-> None is also allowed now. Patch by jpe. (Github issue
:issue:`6946`)
* The runtime Python dispatch for fused functions is
substantially faster. (Github issues :issue:`1385`,
:issue:`6996`)
* Freelists (via cdef class decorator and for internally used
types such as async) are now also used in the Limited API and
with extension type specs enabled. (Github issue
:issue:`7151`)
* Module imports now quickly check for an already imported
module to speed up reimports. Patch by Lysandros Nikolaou.
(Github issue :issue:`7035`)
* Type checks on PEP-604 union types (int | None) are optimised
into separate checks. (Github issue :issue:`6935`)
* Assignments to the PEP-604 union type float | None allow any
suitable Python number as input and convert it to a Python
float automatically. (Github issue :issue:`5750`)
* Item type inference was improved for looping over literals.
(Github issue :issue:`6912`)
* Looping over literal sequences and strings now uses efficient
C array looping if possible. (Github issue :issue:`6926`)
* Releasing the GIL from an unknown lock state is more
efficient. (Github issue :issue:`6847`)
* cython.critical_section(PyMutex) now works, as with Python
objects. (Github issue :issue:`6847`)
* bool(c_int/float/ptr) avoid passing through Python objects.
(Github issue :issue:`7015`)
* Variables assigned inside of prange loops can now be
initialised outside of the loop. (Github issue :issue:`7178`)
* Unused exceptions in except clauses are detected in some more
cases to avoid their normalisation. (Github issue
:issue:`7021`)
* Mixed operations on C integers with Python ints use less code
and are more streamlined for Py3.12+. (Github issue
:issue:`7244`)
* Some object constants are now marked as immortal to speed up
their reference counting in recent CPython versions. This
can be configured with the CYTHON_IMMORTAL_CONSTANTS C macro.
(Github issue :issue:`7118`)
* Further improvements were made to reduce the size of the
resulting extension modules. (Github issue :issue:`6983`,
:issue:`7199`, :issue:`7220`, :issue:`7238`, :issue:`7255`,
:issue:`7265`)
* Several improvements were made in freethreaded Python code.
(Github issues :issue:`6936`, :issue:`6939`, :issue:`6949`,
:issue:`6984`, :issue:`7011`, :issue:`7066`, :issue:`7114`,
:issue:`7200`)
* Several improvements were made for the Limited API. (Github
issues :issue:`6959`, :issue:`6991`)
* Several improvements were made for the GraalPython support.
Patch by Michael Šimáček. (Github issue :issue:`7074`)
* Some GIL-safe C-API wrappers were added to the libc/libcpp
declarations. (Github issue :issue:`6829`, :issue:`6993`)
* String and number constants use less storage space in the
module. (Github issues :issue:`6971`, :issue:`6978`,
:issue:`6986`)
* The managed dict/weakref support in CPython 3.12+ is used for
internal types to benefit from future CPython optimisations
here. (Github issue :issue:`6891`)
* Using NaN as exception return value is supported. (Github
issues :issue:`6900`, :issue:`6903`)
* Declarations for C++ condition variables were added. (Github
issue :issue:`6836`)
* The annotated source HTML page shows alternating +/ markers
to open/close lines. Patch by Kamil Monicz. (Github issue
:issue:`7099`)
* cython --embed gained a new option --embed-modules=… to list
further extension modules that will be statically linked into
the generated extension module, to get them initialised on
application start. (Github issue :issue:`2849`)
* The setup.py script of Cython now allows passing the desired
Limited API version like --cython-limited-api=3.11. (Github
issue :issue:`7228`)
* Unicode 16.0.0 is used to parse identifiers. (Github issue
:issue:`6836`)
* Special float exception values could generate invalid C code.
(Github issues :issue:`6900`, :issue:`6903`)
* References to the Python bool type could generate invalid C
code. (Github issue :issue:`6902`)
* Using cython.pymutex in an extension type declared as public
or api generated invalid C code missing the required PyMutex
declarations. (Github issues :issue:`6992`, :issue:`6995`)
* Cython's type sharing across modules suffered from race
conditions if multiple modules tried to initialise and share
their types concurrently. This is due to an underlying
CPython issue and cannot easily be worked around completely.
In the common case that module dicts are plain Python dict
objects, however, Cython now uses a .setdefault() equivalent
for thread-safe type sharing. See
https://github.com/python/cpython/issues/137422 (Github issue
:issue:`7076`)
* Cython incorrectly called PyList_GetItemRef() in PyPy and
GraalPython before Py3.13. (Github issue :issue:`7269`)
* Iterating over temporary memoryviews could crash Cython.
(Github issue :issue:`7005`)
* Type casts on constants as part of numeric expressions could
crash Cython. (Github issue :issue:`6779`)
* Long code bodies in with statements could crash Cython.
(Github issue :issue:`7122`)
* Vectorcalls could use needless temp assignments for self.
(Github issue :issue:`6909`)
* Indexing bytes failed to optimise in some cases. (Github
issue :issue:`6997`)
* Optimised C integer formatting in f-strings failed to apply
to typedef types. (Github issue :issue:`7170`)
* In auto-pickling, trying to unpickle an object that has no
__dict__ from object pickle data that includes instance dict
state is now an error. (Github issue :issue:`7222`)
* The type objects of heap types were not always correctly
decrefed on deallocation. (Github issue :issue:`7145`)
* Pure mode type aliases like p_int or ulong leaked into some C
type contexts, risking to conflict with user declarations.
(Github issues :issue:`6922`, :issue:`6339`)
* Boolean (emptyness) tests on builtin containers could fail to
handle (unlikely) errors. (Github issue :issue:`7090`)
* The return type of bytes.join() was sometimes inferred as
plain object. (Github issue :issue:`6987`)
* Type inference could fail to understand prange() arguments.
(Github issue :issue:`6974`)
* embedsignatures failed if lambda was used in function default
arguments. (Github issue :issue:`6880`)
* An internal C function was not marked as static and leaked a
linker symbol. (Github issue :issue:`6957`)
* PyType_FromModuleAndSpec was incorrectly used in Limited API
code before Py3.10. (Github issue :issue:`7181`)
* Conversion code for memoryview dtypes from and to Python
objects generated C warnings about incorrect const / non-
const casting code. (Github issue :issue:`7219`)
* Cython's tools and frontend scripts now use python3 instead
of just python in their shebang line. Patch by Matti Picus.
(Github issue :issue:`7053`)
* Extension arguments defined for the shared code module were
ignored in cythonize(). (Github issue :issue:`7251`)
* Failures while following package attributes in import
pkg.module as … were not handled.
* Trying to instantiate internal types used by Cython is now
prohibited. (Github issue :issue:`7263`)
* The setup.py script in the Demos/ subdirectory failed to
build. (Github issue :issue:`7228`)
* The cygdb program failed to work with virtualenvs on Windows.
Patch by Merlin. (Github issue :issue:`7268`)
* Includes all fixes as of Cython 3.1.6.
* Some lesser used platforms (Windows ARM/i686, macOS x86_64,
Linux i686, musllinux) now use Py3.9 abi3 binary wheels
instead of Python version specific wheels. We also added an
abi3 wheel for armv7l. (Github issues :issue:`7227`,
:issue:`7248`, :issue:`7250`)
* Usages of Py_TPFLAGS_HAVE_FINALIZE were removed. The
constant remains available as cimport from cpython.object for
legacy reasons. (Github issue :issue:`6423`)
* Using cython.pymutex in an extension type declared as public
or api generated invalid C code missing the required PyMutex
declarations. (Github issues :issue:`6992`, :issue:`6995`)
* 3.2.0b2 generated incorrect pointer casts in the cimport
importing code. (Github issue :issue:`7268`)
* Cython's type sharing across modules suffered from race
conditions if multiple modules tried to initialise and share
their types concurrently. This is due to an underlying

* The code generated for importing and exporting cimports
across modules uses less space. (Github issues :issue:`7255`,
:issue:`7265`)
* Iteration over memoryviews could loop indefinitely in 3.2b1
when encountering a continue statement. (Github issue
:issue:`7259`)

* The musllinux platform is now served with an abi3 Cython
wheel instead of Python specific ones. (Github issue
:issue:`7250`)
* Builtin exception types are now inferred. (Github issue
:issue:`6908`)
* The list of known, inferred and optimised Python builtins was
updated. range is now considered a type. ascii, bin, format,
hex, oct were added as functions. (Github issue
:issue:`6931`)
* The f-string syntax was extended according to PEP-701.
(Github issue :issue:`5452`)
* t-strings are implemented according to PEP-750. The
implementation backports the template classes but prefers
existing backports if installed separately. (Github issue
:issue:`6811`)
* Unknown return type annotations with -> are no longer
rejected but produce warnings. This allows better integration
with Python type hints that are not always usable for Cython.
-> None is also allowed now. Patch by jpe. (Github issue
:issue:`6946`)
* The runtime Python dispatch for fused functions is
substantially faster. (Github issues :issue:`1385`,
:issue:`6996`)
* Freelists (via cdef class decorator and for internally used
types such as async) are now also used in the Limited API and
with extension type specs enabled. (Github issue
:issue:`7151`)
* Module imports now quickly check for an already imported
module to speed up reimports. Patch by Lysandros Nikolaou.
(Github issue :issue:`7035`)
* Type checks on PEP-604 union types (int | None) are optimised
into separate checks. (Github issue :issue:`6935`)
* Assignments to the PEP-604 union type float | None allow any
suitable Python number as input and convert it to a Python
float automatically. (Github issue :issue:`5750`)
* Item type inference was improved for looping over literals.
(Github issue :issue:`6912`)
* Looping over literal sequences and strings now uses efficient
C array looping if possible. (Github issue :issue:`6926`)
* Releasing the GIL from an unknown lock state is more
efficient. (Github issue :issue:`6847`)
* cython.critical_section(PyMutex) now works, as with Python
objects. (Github issue :issue:`6847`)
* bool(c_int/float/ptr) avoid passing through Python objects.
(Github issue :issue:`7015`)
* Variables assigned inside of prange loops can now be
initialised outside of the loop. (Github issue :issue:`7178`)
* Unused exceptions in except clauses are detected in some more
cases to avoid their normalisation. (Github issue
:issue:`7021`)
* Mixed operations on C integers with Python ints use less code
and are more streamlined for Py3.12+. (Github issue
:issue:`7244`)
* Some object constants are now marked as immortal to speed up
their reference counting in recent CPython versions. This
can be configured with the CYTHON_IMMORTAL_CONSTANTS C macro.
(Github issue :issue:`7118`)
* Further improvements were made to reduce the size of the
resulting extension modules. (Github issue :issue:`6983`,
:issue:`7199`, :issue:`7220`, :issue:`7238`)
* Several improvements were made in freethreaded Python code.
(Github issues :issue:`6936`, :issue:`6939`, :issue:`6949`,
:issue:`6984`, :issue:`7011`, :issue:`7066`, :issue:`7114`,
:issue:`7200`)
* Several improvements were made for the Limited API. (Github
issues :issue:`6959`, :issue:`6991`)
* Several improvements were made for the GraalPython support.
Patch by Michael Šimáček. (Github issue :issue:`7074`)
* Some GIL-safe C-API wrappers were added to the libc/libcpp
declarations. (Github issue :issue:`6829`, :issue:`6993`)
* String and number constants use less storage space in the
module. (Github issues :issue:`6971`, :issue:`6978`,
:issue:`6986`)
* The managed dict/weakref support in CPython 3.12+ is used for
internal types to benefit from future CPython optimisations
here. (Github issue :issue:`6891`)
* Using NaN as exception return value is supported. (Github
issues :issue:`6900`, :issue:`6903`)
* Declarations for C++ condition variables were added. (Github
issue :issue:`6836`)
* The annotated source HTML page shows alternating +/ markers
to open/close lines. Patch by Kamil Monicz. (Github issue
:issue:`7099`)
* cython --embed gained a new option --embed-modules=… to list
further extension modules that will be statically linked into
the generated extension module, to get them initialised on
application start. (Github issue :issue:`2849`)
* The setup.py script of Cython now allows passing the desired
Limited API version like --cython-limited-api=3.11. (Github
issue :issue:`7228`)
* Unicode 16.0.0 is used to parse identifiers. (Github issue
:issue:`6836`)
* Special float exception values could generate invalid C code.
(Github issues :issue:`6900`, :issue:`6903`)
* References to the Python bool type could generate invalid C
code. (Github issue :issue:`6902`)
* Unicode characters formatted from C integers with
f"{value:c}" could result in invalid Python string objects
since Cython 3.1.0. (Github issue :issue:`7240`)
* Vectorcalls could use needless temp assignments for self.
(Github issue :issue:`6909`)
* Iterating over temporary memoryviews could crash Cython.
(Github issue :issue:`7005`)
* Type casts on constants as part of numeric expressions could
crash Cython. (Github issue :issue:`6779`)
* Long code bodies in with statements could crash Cython.
(Github issue :issue:`7122`)
* Indexing bytes failed to optimise in some cases. (Github
issue :issue:`6997`)
* Optimised C integer formatting in f-strings failed to apply
to typedef types. (Github issue :issue:`7170`)
* In auto-pickling, trying to unpickle an object that has no
__dict__ from object pickle data that includes instance dict
state is now an error. (Github issue :issue:`7222`)
* The type objects of heap types were not always correctly
decrefed on deallocation. (Github issue :issue:`7145`)
* Pure mode type aliases like p_int or ulong leaked into some C
type contexts, risking to conflict with user declarations.
(Github issues :issue:`6922`, :issue:`6339`)
* Boolean (emptyness) tests on builtin containers could fail to
handle (unlikely) errors. (Github issue :issue:`7090`)
* The return type of bytes.join() was sometimes inferred as
plain object. (Github issue :issue:`6987`)
* Type inference could fail to understand prange() arguments.
(Github issue :issue:`6974`)
* embedsignatures failed if lambda was used in function default
arguments. (Github issue :issue:`6880`)
* An internal C function was not marked as static and leaked a
linker symbol. (Github issue :issue:`6957`)
* PyType_FromModuleAndSpec was incorrectly used in Limited API
code before Py3.10. (Github issue :issue:`7181`)
* Conversion code for memoryview dtypes from and to Python
objects generated C warnings about incorrect const / non-
const casting code. (Github issue :issue:`7219`)
* cythonize (program and function) now uses
concurrent.futures.ProcessPoolExecutor instead of
multiprocessing.Pool to fix a hang on build failures in
parallel builds. A possible work-around is to disable
parallel builds. Patch by Sviatoslav Sydorenko. (Github
issue :issue:`7183`)
* Cython's tools and frontend scripts now use python3 instead
of just python in their shebang line. Patch by Matti Picus.
(Github issue :issue:`7053`)
* The setup.py script in the Demos/ subdirectory failed to
build. (Github issue :issue:`7228`)
* Includes all fixes as of Cython 3.1.5.
* Some lesser used platforms (Windows ARM/i686, macOS x86_64,
Linux i686) now use Py3.9 abi3 binary wheels instead of
Python version specific wheels. We also added a abi3 wheel
for armv7l. (Github issues :issue:`7227`, :issue:`7248`)
* Usages of Py_TPFLAGS_HAVE_FINALIZE were removed. The
constant remains available as cimport from cpython.object for
legacy reasons. (Github issue :issue:`6423`)
* Some internal C symbols were not declared as static,
preventing static linking of multiple modules. Patch by Yury
Popov. (Github issue :issue:`7310`)
* Accidentally using except + in C mode did not raise a compile
error but generated invalid C code leading to obscure error
messages. Patch by user202729. (Github issue :issue:`6560`)
* Unicode characters formatted from C integers with padding, as
in f"{value:XXc}", could result in invalid Python string
objects since Cython 3.1.0. Also, lone surrogates failed to
format in this way. (Github issue :issue:`7298`)
* Assigning nested structs from a list of structs (item by
item) could crash Cython. (Github issue :issue:`7308`)
* Cython incorrectly called PyList_GetItemRef() in PyPy and
GraalPython before Py3.13. (Github issue :issue:`7269`)
* Trying to instantiate internal types used by Cython is now
prohibited. (Github issue :issue:`7263`)
* Unicode characters formatted from C integers with
f"{value:c}" could result in invalid Python string objects
since Cython 3.1.0. (Github issue :issue:`7240`)
* cythonize (program and function) now uses
concurrent.futures.ProcessPoolExecutor instead of
multiprocessing.Pool to fix a hang on build failures in
parallel builds. A possible work-around is to disable
parallel builds. Patch by Sviatoslav Sydorenko. (Github
issue :issue:`7183`)
* Conversion from C++ strings longer than PY_SSIZE_T_MAX did
not validate the length.
* Some non-Limited API code was incorrectly used in generated
header files. (Github issue :issue:`7157`)
* Optimised unpacking of Python integers in expressions uses a
slightly safer scheme. (Github issue :issue:`7134`)
* Empty return statements were not always reported when
tracing. (Github issue :issue:`7022`)
* Value conversion errors when tracing C return statements no
longer fail the trace but fall back to reporting None returns
instead. (Github issue :issue:`6503`)

- 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.
