Changelog for python310-Cython-0.29.32-1.2.x86_64.rpm :

* Tue Aug 02 2022 Otto Hollmann - Update to 0.29.32: - Bugs fixed:
* Revert \"Using memoryview typed arguments in inner functions is now rejected as unsupported.\"
* from module import
* failed in 0.29.31 when using memoryviews- Changes from 0.29.31: - Features added:
* A new argument --module-name was added to the cython command to provide the (one) exact target module name from the command line. - Bugs fixed:
* Use importlib.util.find_spec() instead of the deprecated importlib.find_loader() function when setting up the package path at import-time.
* Require the C compiler to support the two-arg form of va_start on Python 3.10 and higher.
* Make fused_type subscriptable in Shadow.py.
* Fix the incorrect code generation of the target type in bytearray loops.
* Atomic refcounts for memoryviews were not used on some GCC versions by accident.
* Silence some GCC -Wconversion warnings in C utility code.
* Tuple multiplication was ignored in expressions such as [
*(1,)
* 2].
* Calling append methods on extension types could fail to find the method in some cases.
* Ensure that object buffers (e.g. ndarray[object, ndim=1]) containing NULL pointers are safe to use, returning None instead of the NULL pointer.
* Using memoryview typed arguments in inner functions is now rejected as unsupported.
* Compilation could fail on systems (e.g. FIPS) that block MD5 checksums at runtime.
* Experimental adaptations for the CPython \"nogil\" fork was added. Note that there is no official support for this in Cython 0.x.
* Wed May 18 2022 Paolo Stivanin - 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.
* Sun Mar 20 2022 Dirk Müller - update to 0.29.28:
* Due to backwards incompatible changes in CPython 3.11a4, the feature flags ``CYTHON_FAST_THREAD_STATE`` and ``CYTHON_USE_EXC_INFO_STACK`` are now disabled in Python 3.11 and later. They are enabled again in Cython 3.0. Patch by David Woods. (Github issue #4610)
* A C compiler warning in older PyPy versions was resolved. Patch by Matti Picus. (Github issue #4236)
* Wed Feb 02 2022 Matej Cepl - Make the running the test suite conditional (default off). Seven hours of running it is just too much.
* Mon Jan 31 2022 Matej Cepl - Enable running of the test suite.
* Mon Jan 31 2022 Paolo Stivanin - update to 0.29.27:
* The ``cythonize`` command has a new option ``-M`` to generate ``.dep`` dependency files for the compilation unit. This can be used by external build tools to track these dependencies.
* Calls to ``range()`` with more than three arguments did not fail.
* Some C compiler warnings about missing type struct initialisers in Py3.10 were resolved.
* Cython no longer warns about using OpenMP 3.0 features since they are now considered generally available.
* Tue Jan 04 2022 Dirk Müller - update to 0.29.26:
* An incompatibility with CPython 3.11.0a3 was resolved.
* The ``in`` operator failed on literal lists with starred expressions.
* A C compiler warning in PyPy about a missing struct field initialisation was resolved.
* Mon Dec 06 2021 Dirk Müller - update to 0.29.25:
* Several incompatibilities with CPython 3.11 were resolved.
* Some C compiler warnings were resolved.
* C++ ``std::move()`` should only be used automatically in MSVC versions that support it.
* The ``Py_hash_t`` type failed to accept arbitrary \"index\" values.
* Avoid copying unaligned 16-bit values since some platforms require them to be aligned. Use memcpy() instead to let the C compiler decide how to do it.
* Cython crashed on invalid truthiness tests on C++ types without ``operator bool``.
* The declaration of ``PyUnicode_CompareWithASCIIString()`` in ``cpython.unicode`` was incorrect.
* Wed Jul 14 2021 Paolo Stivanin - Update to 0.29.24:
* Inline functions in pxd files that used memory views could lead to invalid 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``.- Drop cython_use_imgmath.patch

* ``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.

* Pythran calls to NumPy methods no longer generate useless method lookup code.
* The PyUnicode_GET_LENGTH() macro was missing from the cpython.
* declarations
* The deprecated PyUnicode_
*() C-API functions are no longer used, except for Unicode strings that contain lone surrogates. Unicode strings that contain non-BMP characters or surrogate pairs now generate different C code on 16-bit Python 2.x Unicode deployments (such as MS-Windows). Generating the C code on Python 3.x is recommended in this case
* Some template parameters were missing from the C++ std::unordered_map declaration
* Several internal code generation issues regarding temporary variables were resolved
* Thu Jun 11 2020 Paolo Stivanin - Update to 0.29.20
* Nested try-except statements with multiple return statements could crash due to incorrect deletion of the except as target variable.
* The AATTclassmethod decorator no longer rejects unknown input from other decorators.

* The C++ typeid() function was allowed in C mode
* The error position reported for errors found in f-strings was misleading
* The new c_api_binop_methods directive was added for forward compatibility, but can only be set to True (the current default value). It can be disabled in Cython 3.0
* Thu May 21 2020 Paolo Stivanin - Update to 0.29.19
* Exception position reporting could run into race conditions on threaded code. It now uses function-local variables again.
* Error handling early in the module init code could lead to a crash.
* Error handling in cython.array creation was improved to avoid calling C-API functions with an error held.
* A memory corruption was fixed when garbage collection was triggered during calls to PyType_Ready() of extension type subclasses. (Github issue #3603)
* Memory view slicing generated unused error handling code which could negatively impact the C compiler optimisations for parallel OpenMP code etc. Also, it is now helped by static branch hints. (Github issue #2987)
* Cython\'s built-in OpenMP functions were not translated inside of call arguments. Original patch by Celelibi and David Woods. (Github issue #3594)
* Complex buffer item types of structs of arrays could fail to validate.

Patches by Pablo Galindo and Orivej Desh (Github issues #3171, #3201). + ? for bool was missing from the supported NumPy dtypes. Patch by Max Klein. (Github issue #2675) + await was not allowed inside of f-strings. Patch by Dmitro Getz. (Github issue #2877) + Coverage analysis failed for projects where the code resides in separate source sub-directories. Patch by Antonio Valentino. (Github issue #1985) + An incorrect compiler warning was fixed in automatic C++ string conversions. Patch by Gerion Entrup.

Patch by Josh Tobin. (Github issue #2967) + Support slice handling in newer Pythran versions. Patch by Serge Guelton. (Github issue #2989) + A reference leak in power-of-2 calculation was fixed. Patch by Sebastian Berg. (Github issue #3022) + The search order for include files was changed. Previously it was include_directories, Cython/Includes, sys.path. Now it is include_directories, sys.path, Cython/Includes. This was done to allow third-party
*.pxd files to override the ones in Cython. Original patch by Matti Picus. (Github issue #2905) + Setting language_level=2 in a file did not work if language_level=3 was enabled globally before. Patch by Jeroen Demeyer. (Github issue #2791)
* Wed Jun 12 2019 Tomáš Chvátal - Say goodbye to -doc subpackage as the documentation is online and does not build with latest sphinx releases (even in master at the moment).- The testing in -doc spec was disabled anyway and if needed we will reintroduce it as a multibuild

* Sun Jan 20 2019 Arun Persaud - specfile:
* update copyright year- update to version 0.29.3:
* Some C code for memoryviews was generated in a non-deterministic order. Patch by Martijn van Steenbergen. (Github issue #2779)

* Sat Dec 01 2018 Arun Persaud - update to version 0.29.1:
* Bugs fixed + Extensions compiled with MinGW-64 under Windows could misinterpret integer objects larger than 15 bit and return incorrect results. (Github issue #2670) + Cython no longer requires the source to be writable when copying its data into a memory view slice. Patch by Andrey Paramonov. (Github issue #2644) + Line tracing of try-statements generated invalid C code. (Github issue #2274) + When using the warn.undeclared directive, Cython\'s own code generated warnings that are now fixed. Patch by Nicolas Pauss. (Github issue #2685) + Cython\'s memoryviews no longer require strides for setting the shape field but only the PyBUF_ND flag to be set. Patch by John Kirkham. (Github issue #2716) + Some C compiler warnings about unused memoryview code were fixed. Patch by Ho Cheuk Ting. (Github issue #2588) + A C compiler warning about implicit signed/unsigned conversion was fixed. (Github issue #2729) + Assignments to C++ references returned by operator[] could fail to compile. (Github issue #2671) + The power operator and the support for NumPy math functions were fixed in Pythran expressions. Patch by Serge Guelton. (Github issues #2702, #2709) + Signatures with memory view arguments now show the expected type when embedded in docstrings. Patch by Matthew Chan and Benjamin Weigel. (Github issue #2634) + Some from ... cimport ... constructs were not correctly considered when searching modified dependencies in cythonize() to decide whether to recompile a module. Patch by Kryštof Pilnáček. (Github issue #2638) + A struct field type in the cpython.array declarations was corrected. Patch by John Kirkham. (Github issue #2712)
* Wed Oct 17 2018 Arun Persaud - update to version 0.29:
* Features added + PEP-489 multi-phase module initialisation has been enabled again. Module reloads in other subinterpreters raise an exception to prevent corruption of the static module state. + A set of mypy compatible PEP-484 declarations were added for Cython\'s C data types to integrate with static analysers in typed Python code. They are available in the Cython/Shadow.pyi module and describe the types in the special cython module that can be used for typing in Python code. Original patch by Julian Gethmann. (Github issue #1965) + Memoryviews are supported in PEP-484/526 style type declarations. (Github issue #2529) + AATTcython.nogil is supported as a C-function decorator in Python code. (Github issue #2557) + Raising exceptions from nogil code will automatically acquire the GIL, instead of requiring an explicit with gil block. + C++ functions can now be declared as potentially raising both C++ and Python exceptions, so that Cython can handle both correctly. (Github issue #2615) + cython.inline() supports a direct language_level keyword argument that was previously only available via a directive. + A new language level name 3str was added that mostly corresponds to language level 3, but keeps unprefixed string literals as type \'str\' in both Py2 and Py3, and the builtin \'str\' type unchanged. This will become the default in the next Cython release and is meant to help user code a) transition more easily to this new default and b) migrate to Python 3 source code semantics without making support for Python 2.x difficult. + In CPython 3.6 and later, looking up globals in the module dict is almost as fast as looking up C globals. (Github issue #2313) + For a Python subclass of an extension type, repeated method calls to non-overridden cpdef methods can avoid the attribute lookup in Py3.6+, which makes them 4x faster. (Github issue [#2313]) + (In-)equality comparisons of objects to integer literals are faster. (Github issue #2188) + Some internal and 1-argument method calls are faster. + Modules that cimport many external extension types from other Cython modules execute less import requests during module initialisation. + Constant tuples and slices are deduplicated and only created once per module. (Github issue #2292) + The coverage plugin considers more C file extensions such as .cc and .cxx. (Github issue #2266) + The cythonize command accepts compile time variable values (as set by DEF) through the new -E option. Patch by Jerome Kieffer. (Github issue #2315) + pyximport can import from namespace packages. Patch by Prakhar Goel. (Github issue #2294) + Some missing numpy and CPython C-API declarations were added. Patch by John Kirkham. (Github issues #2523, #2520, [#2537]) + Declarations for the pylifecycle C-API functions were added in a new .pxd file cpython.pylifecycle. + The Pythran support was updated to work with the latest Pythran 0.8.7. Original patch by Adrien Guinet. (Github issue #2600) + %a is included in the string formatting types that are optimised into f-strings. In this case, it is also automatically mapped to %r in Python 2.x. + New C macro CYTHON_HEX_VERSION to access Cython\'s version in the same style as PY_HEX_VERSION. + Constants in libc.math are now declared as const to simplify their handling. + An additional check_size clause was added to the ctypedef class name specification to allow suppressing warnings when importing modules with backwards-compatible PyTypeObject size changes. Patch by Matti Picus. (Github issue #2627)
* Bugs fixed + The exception handling in generators and coroutines under CPython 3.7 was adapted to the newly introduced exception stack. Users of Cython 0.28 who want to support Python 3.7 are encouraged to upgrade to 0.29 to avoid potentially incorrect error reporting and tracebacks. (Github issue #1958) + Crash when importing a module under Stackless Python that was built for CPython. Patch by Anselm Kruis. (Github issue #2534) + 2-value slicing of typed sequences failed if the start or stop index was None. Patch by Christian Gibson. (Github issue #2508) + Multiplied string literals lost their factor when they are part of another constant expression (e.g. \'x\'
* 10 + \'y\' => \'xy\'). + String formatting with the \'%\' operator didn\'t call the special __rmod__() method if the right side is a string subclass that implements it. (Python issue 28598) + The directive language_level=3 did not apply to the first token in the source file. (Github issue #2230) + Overriding cpdef methods did not work in Python subclasses with slots. Note that this can have a performance impact on calls from Cython code. (Github issue #1771) + Fix declarations of builtin or C types using strings in pure python mode. (Github issue #2046) + Generator expressions and lambdas failed to compile in AATTcfunc functions. (Github issue #459) + Global names with const types were not excluded from star-import assignments which could lead to invalid C code. (Github issue [#2621]) + Several internal function signatures were fixed that lead to warnings in gcc-8. (Github issue #2363) + The numpy helper functions set_array_base() and get_array_base() were adapted to the current numpy C-API recommendations. Patch by Matti Picus. (Github issue #2528) + Some NumPy related code was updated to avoid deprecated API usage. Original patch by jbrockmendel. (Github issue #2559) + Several C++ STL declarations were extended and corrected. Patch by Valentin Valls. (Github issue #2207) + C lines of the module init function were unconditionally not reported in exception stack traces. Patch by Jeroen Demeyer. (Github issue #2492) + When PEP-489 support is enabled, reloading the module overwrote any static module state. It now raises an exception instead, given that reloading is not actually supported. + Object-returning, C++ exception throwing functions were not checking that the return value was non-null. Original patch by Matt Wozniski (Github Issue #2603) + The source file encoding detection could get confused if the c_string_encoding directive appeared within the first two lines. (Github issue #2632) + Cython generated modules no longer emit a warning during import when the size of the NumPy array type is larger than what was found at compile time. Instead, this is assumed to be a backwards compatible change on NumPy side.
* Other changes + Cython now emits a warning when no language_level (2, 3 or \'3str\') is set explicitly, neither as a cythonize() option nor as a compiler directive. This is meant to prepare the transition of the default language level from currently Py2 to Py3, since that is what most new users will expect these days. The future default will, however, not enforce unicode literals, because this has proven a major obstacle in the support for both Python 2.x and 3.x. The next major release is intended to make this change, so that it will parse all code that does not request a specific language level as Python 3 code, but with str literals. The language level 2 will continue to be supported for an indefinite time. + The documentation was restructured, cleaned up and examples are now tested. The NumPy tutorial was also rewritten to simplify the running example. Contributed by Gabriel de Marmiesse. (Github issue #2245) + Cython compiles less of its own modules at build time to reduce the installed package size to about half of its previous size. This makes the compiler slightly slower, by about 5-7%.
* Sat Aug 11 2018 arunAATTgmx.de- update to version 0.28.5:
* The discouraged usage of GCC\'s attribute optimize(\"Os\") was replaced by the similar attribute cold to reduce the code impact of the module init functions. (Github issue #2494)
* A reference leak in Py2.x was fixed when comparing str to unicode for equality.
* Thu Jul 12 2018 arunAATTgmx.de- update to version 0.28.4:
* Bugs fixed + Reallowing tp_clear() in a subtype of an AATTno_gc_clear extension type generated an invalid C function call to the (non-existent) base type implementation. (Github issue #2309) + Exception catching based on a non-literal (runtime) tuple could fail to match the exception. (Github issue #2425) + Compile fix for CPython 3.7.0a2. (Github issue #2477)
* Sun May 27 2018 arunAATTgmx.de- update to version 0.28.3:
* Set iteration was broken in non-CPython since 0.28.
* UnicodeEncodeError in Py2 when %s formatting is optimised for unicode strings. (Github issue #2276)
* Work around a crash bug in g++ 4.4.x by disabling the size reduction setting of the module init function in this version. (Github issue #2235)
* Wed Apr 18 2018 toddrme2178AATTgmail.com- Version update to 0.28.2 + Features added
* ``abs()`` is faster for Python long objects.
* The C++11 methods ``front()`` and ``end()`` were added to the declaration of ``libcpp.string``. Patch by Alex Huszagh. (Github issue #2123)
* The C++11 methods ``reserve()`` and ``bucket_count()`` are declared for ``std::unordered_map``. Patch by Valentin Valls. (Github issue #2168) + Bugs fixed
* The copy of a read-only memoryview was considered read-only as well, whereas a common reason to copy a read-only view is to make it writable. The result of the copying is now a writable buffer by default. (Github issue #2134)
* The ``switch`` statement generation failed to apply recursively to the body of converted if-statements.
* ``NULL`` was sometimes rejected as exception return value when the returned type is a fused pointer type. Patch by Callie LeFave. (Github issue #2177)
* Fixed compatibility with PyPy 5.11. Patch by Matti Picus. (Github issue #2165) + Other changes
* The NumPy tutorial was rewritten to use memoryviews instead of the older buffer declaration syntax. Contributed by Gabriel de Marmiesse. (Github issue #2162)
* Mon Mar 19 2018 tchvatalAATTsuse.com- Version update to 0.28.1:
* PyFrozenSet_New() was accidentally used in PyPy where it is lacking from the C-API.
* Assignment between some C++ templated types were incorrectly rejected when the templates mix const with ctypedef. (Github issue #2148)
* Undeclared C++ no-args constructors in subclasses could make the compilation fail if the base class constructor was declared without nogil. (Github issue #2157)
* Bytes %-formatting inferred basestring (bytes or unicode) as result type in some cases where bytes would have been safe to infer. (Github issue #2153)
* None was accidentally disallowed as typed return value of dict.pop().
* Sat Mar 17 2018 arunAATTgmx.de- update to version 0.28:
* Features added + Cdef classes can now multiply inherit from ordinary Python classes. (The primary base must still be a c class, possibly object, and the other bases must not be cdef classes.) + Type inference is now supported for Pythran compiled NumPy expressions. Patch by Nils Braun. (Github issue #1954) + The const modifier can be applied to memoryview declarations to allow read-only buffers as input. (Github issues #1605, #1869) + C code in the docstring of a cdef extern block is copied verbatimly into the generated file. Patch by Jeroen Demeyer. (Github issue #1915) + When compiling with gcc, the module init function is now tuned for small code size instead of whatever compile flags were provided externally. Cython now also disables some code intensive optimisations in that function to further reduce the code size. (Github issue #2102) + Decorating an async coroutine with AATTcython.iterable_coroutine changes its type at compile time to make it iterable. While this is not strictly in line with PEP-492, it improves the interoperability with old-style coroutines that use yield from instead of await. + The IPython magic has preliminary support for JupyterLab. (Github issue #1775) + The new TSS C-API in CPython 3.7 is supported and has been backported. Patch by Naotoshi Seo. (Github issue #1932) + Cython knows the new Py_tss_t type defined in PEP-539 and automatically initialises variables declared with that type to Py_tss_NEEDS_INIT, a value which cannot be used outside of static assignments. + The set methods .remove() and .discard() are optimised. Patch by Antoine Pitrou. (Github issue #2042) + dict.pop() is optimised. Original patch by Antoine Pitrou. (Github issue #2047) + Iteration over sets and frozensets is optimised. (Github issue [#2048]) + Safe integer loops (< range(2^30)) are automatically optimised into C loops. + alist.extend([a,b,c]) is optimised into sequential list.append() calls for short literal sequences. + Calls to builtin methods that are not specifically optimised into C-API calls now use a cache that avoids repeated lookups of the underlying C function. (Github issue #2054) + Single argument function calls can avoid the argument tuple creation in some cases. + Some redundant extension type checks are avoided. + Formatting C enum values in f-strings is faster, as well as some other special cases. + String formatting with the \'%\' operator is optimised into f-strings in simple cases. + Subscripting (item access) is faster in some cases. + Some bytearray operations have been optimised similar to bytes. + Some PEP-484/526 container type declarations are now considered for loop optimisations. + Indexing into memoryview slices with view[i][j] is now optimised into view[i, j]. + Python compatible cython.
* types can now be mixed with type declarations in Cython syntax. + Name lookups in the module and in classes are faster. + Python attribute lookups on extension types without instance dict are faster. + Some missing signals were added to libc/signal.pxd. Patch by Jeroen Demeyer. (Github issue #1914) + The warning about repeated extern declarations is now visible by default. (Github issue #1874) + The exception handling of the function types used by CPython\'s type slot functions was corrected to match the de-facto standard behaviour, so that code that uses them directly benefits from automatic and correct exception propagation. Patch by Jeroen Demeyer. (Github issue #1980) + Defining the macro CYTHON_NO_PYINIT_EXPORT will prevent the module init function from being exported as symbol, e.g. when linking modules statically in an embedding setup. Patch by AraHaan. (Github issue #1944)
* Bugs fixed + If a module name is explicitly provided for an Extension() that is compiled via cythonize(), it was previously ignored and replaced by the source file name. It can now be used to override the target module name, e.g. for compiling prefixed accelerator modules from Python files. (Github issue #2038) + The arguments of the num_threads parameter of parallel sections were not sufficiently validated and could lead to invalid C code. (Github issue #1957) + Catching exceptions with a non-trivial exception pattern could call into CPython with a live exception set. This triggered incorrect behaviour and crashes, especially in CPython 3.7. + The signature of the special __richcmp__() method was corrected to recognise the type of the first argument as self. It was previously treated as plain object, but CPython actually guarantees that it always has the correct type. Note: this can change the semantics of user code that previously relied on self being untyped. + Some Python 3 exceptions were not recognised as builtins when running Cython under Python 2. + Some async helper functions were not defined in the generated C code when compiling simple async code. (Github issue #2075) + Line tracing did not include generators and coroutines. (Github issue #1949) + C++ declarations for unordered_map were corrected. Patch by Michael Schatzow. (Github issue #1484) + Iterator declarations in C++ deque and vector were corrected. Patch by Alex Huszagh. (Github issue #1870) + The const modifiers in the C++ string declarations were corrected, together with the coercion behaviour of string literals into C++ strings. (Github issue #2132) + Some declaration types in libc.limits were corrected. Patch by Jeroen Demeyer. (Github issue #2016) + AATTcython.final was not accepted on Python classes with an AATTcython.cclass decorator. (Github issue #2040) + Cython no longer creates useless and incorrect PyInstanceMethod wrappers for methods in Python 3. Patch by Jeroen Demeyer. (Github issue #2105) + The builtin bytearray type could not be used as base type of cdef classes. (Github issue #2106)
