* Wed Jul 08 2020 Ondřej Súkup - Update TO 0.29.21
* Fix a regression in 0.29.20 where __div__ failed to be found in extension types
* Fix a regression in 0.29.20 where a call inside of a finally clause could fail to compile
* Zero-sized buffers could fail to validate as C/Fortran-contiguous.
* exec() did not allow recent Python syntax features in Py3.8+ due to https://bugs.python.org/issue35975
* Binding staticmethods of Cython functions were not behaving like Python methods in Py3
* 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.
* Fused types could leak into unrelated usages. Patch by David Woods.

* 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)

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.

* Sat Jul 06 2019 Arun Persaud - update to version 0.29.11:
* Bugs fixed + Fix compile error in CPython 3.8b2 regarding the PyCode_New() signature. Patch by Nick Coghlan. (Github issue #3009) + Invalid C code generated for lambda functions in cdef methods. 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

* Tue Feb 05 2019 Todd R - Update to 0.29.4
* Division of numeric constants by a runtime value of 0 could fail to raise a ``ZeroDivisionError``. (Github issue #2820)
* 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)
* C89 compatibility was accidentally lost since 0.28. Patches by gastineau and true-pasky. (Github issues #2778, #2801)

* 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)

* Wed Oct 26 2016 toddrme2178AATTgmail.com- update to version 0.25: + Features added
* def/cpdef methods of cdef classes benefit from Cython\'s internal function implementation, which enables introspection and line profiling for them. Implementation sponsored by Turbostream (www.turbostream-cfd.com).
* The distutils extension ``Cython.Distutils.build_ext`` has now been updated to use cythonize which properly handles dependencies. The old extension can still be found in ``Cython.Distutils.old_build_ext`` and is now deprecated.
* Calls to Python functions are faster, following the recent \"FastCall\" optimisations that Victor Stinner implemented for CPython 3.6. See https://bugs.python.org/issue27128 and related issues.
* The new METH_FASTCALL calling convention for PyCFunctions is supported in CPython 3.6. See https://bugs.python.org/issue27810
* C++ classes can now have typedef members. STL containers updated with value_type.
* Support for bazel using a the pyx_library rule in //Tools:rules.bzl.
* Initial support for using Cython modules in Pyston. Patch by Daetalus.

* Building f-strings is faster, especially when formatting C integers.
* for-loop iteration over \"std::string\".
* ``libc/math.pxd`` provides ``e`` and ``pi`` as alias constants to simplify usage as a drop-in replacement for Python\'s math module.
* Speed up cython.inline().
* Binary lshift operations with small constant Python integers are faster.
* Some integer operations on Python long objects are faster in Python 2.7.
* Support for the C++ ``typeid`` operator. + Significant Bugs fixed
* Division of complex numbers avoids overflow by using Smith\'s method.
* Some function signatures in ``libc.math`` and ``numpy.pxd`` were incorrect. Pach by Michael Seifert. + Other changes
* The \"%%cython\" IPython/jupyter magic now defaults to the language level of the current jupyter kernel. The language level can be set explicitly with \"%%cython -2\" or \"%%cython -3\".- update to version 0.24.1:
* IPython cell magic was lacking a good way to enable Python 3 code semantics. It can now be used as \"%%cython -3\".
* Follow a recent change in PEP 492 and CPython 3.5.1 that now requires the __aiter__() method of asynchronous iterators to be a simple def method instead of an async def method.
* Coroutines and generators were lacking the __module__ special attribute.
* C++ std::complex values failed to auto-convert from and to Python complex objects.
* Namespaced C++ types could not be used as memory view types due to lack of name mangling. Patch by Ivan Smirnov.
* Assignments between identical C++ types that were declared with differently typedefed template types could fail.
* Rebuilds could fail to evaluate dependency timestamps in C++ mode. Patch by Ian Henriksen.
* Macros defined in the distutils compiler option do not require values anymore. Patch by Ian Henriksen.
* Minor fixes for MSVC, Cygwin and PyPy.- specfile:
* changed to https for source url
* updated source url to files.pythonhosted.org- update to version 0.24:
* Features added + PEP 498: Literal String Formatting (f-strings). Original patch by Jelle Zijlstra. https://www.python.org/dev/peps/pep-0498/ + PEP 515: Underscores as visual separators in number literals. https://www.python.org/dev/peps/pep-0515/ + Parser was adapted to some minor syntax changes in Py3.6, e.g. https://bugs.python.org/issue9232 + The embedded C code comments that show the original source code can be discarded with the new directive emit_code_comments=False. + Cpdef enums are now first-class iterable, callable types in Python. + Ctuples can now be declared in pure Python code. + Posix declarations for DLL loading and stdio extensions were added. Patch by Lars Buitinck. + The Py2-only builtins unicode(), xrange(), reduce() and long are now also available in compile time DEF expressions when compiling with Py3. + Exception type tests have slightly lower overhead. This fixes ticket 868. + AATTproperty syntax fully supported in cdef classes, old syntax deprecated. + C++ classes can now be declared with default template parameters.
* Bugs fixed + C++ exceptions raised by overloaded C++ operators were not always handled. Patch by Ian Henriksen. + C string literals were previously always stored as non-const global variables in the module. They are now stored as global constants when possible, and otherwise as non-const C string literals in the generated code that uses them. This improves compatibility with strict C compiler options and prevents non-const strings literals with the same content from being incorrectly merged. + Compile time evaluated str expressions (DEF) now behave in a more useful way by turning into Unicode strings when compiling under Python 3. This allows using them as intermediate values in expressions. Previously, they always evaluated to bytes objects. + isinf() declarations in libc/math.pxd and numpy/math.pxd now reflect the actual tristate int return value instead of using bint. + Literal assignments to ctuples avoid Python tuple round-trips in some more corner cases. + Iteration over dict(...).items() failed to get optimised when dict arguments included keyword arguments. + cProfile now correctly profiles cpdef functions and methods.- update to version 0.23.5:
* Compile errors and warnings in integer type conversion code. This fixes ticket 877. Patches by Christian Neukirchen, Nikolaus Rath, Ian Henriksen.
* Reference leak when \"
*args\" argument was reassigned in closures.
* Truth-testing Unicode strings could waste time and memory in Py3.3+.
* Return values of async functions could be ignored and replaced by None.
* Compiler crash in CPython 3.6.
* Fix prange() to behave identically to range(). The end condition was miscalculated when the range was not exactly divisible by the step.
* Optimised all(genexpr)/any(genexpr) calls could warn about unused code. This fixes ticket 876.- Remove unneeded python-Cython-c++11.patch
* Mon Feb 01 2016 toddrme2178AATTgmail.com- update to version 0.23.4:
* Memory leak when calling Python functions in PyPy.
* Compilation problem with MSVC in C99-ish mode.
* Warning about unused values in a helper macro.- update to version 0.23.3:
* Invalid C code for some builtin methods. This fixes ticket 856 again.
* Incorrect C code in helper functions for PyLong conversion and string decoding. This fixes ticket 863, ticket 864 and ticket 865. Original patch by Nikolaus Rath.
* Large folded or inserted integer constants could use too small C integer types and thus trigger a value wrap-around.
* The coroutine and generator types of Cython now also register directly with the Coroutine and Generator ABCs in the backports_abc module if it can be imported. This fixes ticket 870.- update to version 0.23.2:
* Compiler crash when analysing some optimised expressions.
* Coverage plugin was adapted to coverage.py 4.0 beta 2.
* C++ destructor calls could fail when \'&\' operator is overwritten.
* Incorrect C literal generation for large integers in compile-time evaluated DEF expressions and constant folded expressions.
* Byte string constants could end up as Unicode strings when originating from compile-time evaluated DEF expressions.
* Invalid C code when caching known builtin methods. This fixes ticket 860.
* ino_t in posix.types was not declared as unsigned.
* Declarations in libcpp/memory.pxd were missing operator!(). Patch by Leo Razoumov.
* Static cdef methods can now be declared in .pxd files.- update to version 0.23.1:
* Invalid C code for generators. This fixes ticket 858.
* Invalid C code for some builtin methods. This fixes ticket 856.
* Invalid C code for unused local buffer variables. This fixes ticket 154.
* Test failures on 32bit systems. This fixes ticket 857.
* Code that uses \"from xyz import
*\" and global C struct/union/array variables could fail to compile due to missing helper functions. This fixes ticket 851.
* Misnamed PEP 492 coroutine property cr_yieldfrom renamed to cr_await to match CPython.
* Missing deallocation code for C++ object attributes in certain extension class hierarchies.
* Crash when async coroutine was not awaited.
* Compiler crash on yield in signature annotations and default argument values. Both are forbidden now.
* Compiler crash on certain constructs in finally clauses.
* Cython failed to build when CPython\'s pgen is installed.- update to version 0.23:
* Features added + PEP 492 (async/await) was implemented. See https://www.python.org/dev/peps/pep-0492/ + PEP 448 (Additional Unpacking Generalizations) was implemented. See https://www.python.org/dev/peps/pep-0448/ + Support for coverage.py 4.0+ can be enabled by adding the plugin \"Cython.Coverage\" to the \".coveragerc\" config file. + Annotated HTML source pages can integrate (XML) coverage reports. + Tracing is supported in nogil functions/sections and module init code. + When generators are used in a Cython module and the module imports the modules \"inspect\" and/or \"asyncio\", Cython enables interoperability by patching these modules during the import to recognise Cython\'s internal generator and coroutine types. This can be disabled by C compiling the module with \"-D CYTHON_PATCH_ASYNCIO=0\" or \"-D CYTHON_PATCH_INSPECT=0\" + When generators or coroutines are used in a Cython module, their types are registered with the Generator and Coroutine ABCs in the collections or collections.abc stdlib module at import time to enable interoperability with code that needs to detect and process Python generators/coroutines. These ABCs were added in CPython 3.5 and are available for older Python versions through the backports_abc module on PyPI. See https://bugs.python.org/issue24018 + Adding/subtracting/dividing/modulus and equality comparisons with constant Python floats and small integers are faster. + Binary and/or/xor/rshift operations with small constant Python integers are faster. + When called on generator expressions, the builtins all(), any(), dict(), list(), set(), sorted() and unicode.join() avoid the generator iteration overhead by inlining a part of their functionality into the for-loop. + Keyword argument dicts are no longer copied on function entry when they are not being used or only passed through to other function calls (e.g. in wrapper functions). + The PyTypeObject declaration in cpython.object was extended. + The builtin type type is now declared as PyTypeObject in source, allowing for extern functions taking type parameters to have the correct C signatures. Note that this might break code that uses type just for passing around Python types in typed variables. Removing the type declaration provides a backwards compatible fix. + wraparound() and boundscheck() are available as no-ops in pure Python mode. + Const iterators were added to the provided C++ STL declarations. + Smart pointers were added to the provided C++ STL declarations. Patch by Daniel Filonik. + NULL is allowed as default argument when embedding signatures. This fixes ticket 843. + When compiling with --embed, the internal module name is changed to __main__ to allow arbitrary program names, including those that would be invalid for modules. Note that this prevents reuse of the generated C code as an importable module. + External C++ classes that overload the assignment operator can be used. Patch by Ian Henriksen. + Support operator bool() for C++ classes so they can be used in if statements.
* Bugs fixed + Calling \"yield from\" from Python on a Cython generator that returned a value triggered a crash in CPython. This is now being worked around. See https://bugs.python.org/issue23996 + Language level 3 did not enable true division (a.k.a. float division) for integer operands. + Functions with fused argument types that included a generic \'object\' fallback could end up using that fallback also for other explicitly listed object types. + Relative cimports could accidentally fall back to trying an absolute cimport on failure. + The result of calling a C struct constructor no longer requires an intermediate assignment when coercing to a Python dict. + C++ exception declarations with mapping functions could fail to compile when pre-declared in .pxd files. + cpdef void methods are now permitted. + abs(cint) could fail to compile in MSVC and used sub-optimal code in C++. Patch by David Vierra, original patch by Michael Enßlin. + Buffer index calculations using index variables with small C integer types could overflow for large buffer sizes. Original patch by David Vierra. + C unions use a saner way to coerce from and to Python dicts. + When compiling a module foo.pyx, the directories in sys.path are no longer searched when looking for foo.pxd. Patch by Jeroen Demeyer. + Memory leaks in the embedding main function were fixed. Original patch by Michael Enßlin. + Some complex Python expressions could fail to compile inside of finally clauses. + Unprefixed \'str\' literals were not supported as C varargs arguments. + Fixed type errors in conversion enum types to/from Python. Note that this imposes stricter correctness requirements on enum declarations.
* Other changes + Changed mangling scheme in header files generated by cdef api declarations. + Installation under CPython 3.3+ no longer requires a pass of the 2to3 tool. This also makes it possible to run Cython in Python 3.3+ from a source checkout without installing it first. Patch by Petr Viktorin. + jedi-typer.py (in Tools/) was extended and renamed to jedityper.py (to make it importable) and now works with and requires Jedi 0.9. Patch by Tzer-jen Wei.

* Crash when returning values on generator termination.
* In some cases, exceptions raised during internal isinstance() checks were not propagated.
* Runtime reported file paths of source files (e.g for profiling and tracing) are now relative to the build root directory instead of the main source file.

* The internal generator function type was not shared across modules.
* Comparisons of (inferred) ctuples failed to compile.
* Closures inside of cdef functions returning ``void`` failed to compile.

* C++ compilation could fail with an ambiguity error in recent MacOS-X Xcode versions.
* C compilation could fail in pypy3.
* Fixed a memory leak in the compiler when compiling multiple modules.
* When compiling multiple modules, external library dependencies could leak into later compiler runs. Fix by Jeroen Demeyer. This fixes ticket 845.- removed patch fix-32bit.patch as applied upstream
* Wed Apr 22 2015 mciharAATTsuse.cz- Use Source URL from cython.org
* Wed Apr 22 2015 mciharAATTsuse.cz- Add python-numpy as BuildRequires to have more complete test coverage
* Wed Apr 22 2015 mciharAATTsuse.cz- Fix doctests in 32-bit environment (fix-32bit.patch)
* Wed Apr 22 2015 mciharAATTsuse.cz- Update to 0.22: Features added
* C functions can coerce to Python functions, which allows passing them around as callable objects.
* C arrays can be assigned by value and auto-coerce from Python iterables and to Python lists (and tuples).
* Extern C functions can now be declared as cpdef to export them to the module\'s Python namespace. Extern C functions in pxd files export their values to their own module, iff it exists.
* Anonymous C tuple types can be declared as (ctype1, ctype2, ...).
* PEP 479: turn accidental StopIteration exceptions that exit generators into a RuntimeError, activated with future import \"generator_stop\". See http://legacy.python.org/dev/peps/pep-0479/
* Looping over ``reversed(range())`` is optimised in the same way as ``range()``. Patch by Favian Contreras. Bugs fixed
* Mismatching \'except\' declarations on signatures in .pxd and .pyx files failed to produce a compile error.
* Failure to find any files for the path pattern(s) passed into ``cythonize()`` is now an error to more easily detect accidental typos.
* The ``logaddexp`` family of functions in ``numpy.math`` now has correct declarations.
* In Py2.6/7 and Py3.2, simple Cython memory views could accidentally be interpreted as non-contiguous by CPython, which could trigger a CPython bug when copying data from them, thus leading to data corruption. See CPython issues 12834 and 23349. Other changes
* Preliminary support for defining the Cython language with a formal grammar. To try parsing your files against this grammar, use the --formal_grammar directive. Experimental.
* ``_`` is no longer considered a cacheable builtin as it could interfere with gettext.
* Cythonize-computed metadata now cached in the generated C files.
* Thu Feb 05 2015 hpjAATTurpla.net- fix update-alternatives handling in a distribution backwards compatible way
* Fri Jan 09 2015 dimstarAATTopensuse.org- Re-enable test-suite.- Add gcc-c++ BuildRequires: needed for the test-suite to be able to pass.
* Thu Jan 08 2015 dimstarAATTopensuse.org- Fix usage of update-alternatives.
* Thu Dec 18 2014 p.drouandAATTgmail.com- Improve update-alternatives.- Remove Cython-fix-version-detection.patch (got fixed upstream)- update to version 0.21.1:
* Features added - New cythonize option -a to generate the annotated HTML source view. - Missing C-API declarations in cpython.unicode were added. - Passing language=\'c++\' into cythonize() globally enables C++ mode for all modules that were not passed as Extension objects (i.e. only source files and file patterns). - Py_hash_t is a known type (used in CPython for hash values). - PySlice_
*() C-API functions are available from the cpython.slice module. - Allow arrays of C++ classes.
* Bugs fixed - Reference leak for non-simple Python expressions in boolean and/or expressions. - To fix a name collision and to reflect availability on host platforms, standard C declarations [ clock(), time(), struct tm and tm
* functions ] were moved from posix/time.pxd to a new libc/time.pxd. Patch by Charles Blake. - Rerunning unmodified modules in IPython\'s cython support failed. Patch by Matthias Bussonier. - Casting C++ std::string to Python byte strings failed when auto-decoding was enabled. - Fatal exceptions in global module init code could lead to crashes if the already created module was used later on (e.g. through a stale reference in sys.modules or elsewhere). - cythonize.py script was not installed on MS-Windows.
* Other changes - Compilation no longer fails hard when unknown compilation options are passed. Instead, it raises a warning and ignores them (as it did silently before 0.21). This will be changed back to an error in a future release.
* Sun Nov 09 2014 Led - fix bashisms in pre script
* Fri Sep 12 2014 toddrme2178AATTgmail.com- Add Cython-fix-version-detection.patch This is a patch from upstream that restores version information whose removal is preventing several packages from correctly detecting Cython\'s presence. It is already merged upstream and so should be in the next release. Note that despite what upstream says, python-tables/python3-tables is NOT the only package affected by this, which is why the patch is going here instead of python-tables/python3-tables. python-bcolz/python3-bcolz is an example of another package affected.
* Thu Sep 11 2014 toddrme2178AATTgmail.com- Update to 0.21 (2014-09-10)
* Features added
* C (cdef) functions allow inner Python functions.
* Enums can now be declared as cpdef to export their values to the module\'s Python namespace. Cpdef enums in pxd files export their values to their own module, iff it exists.
* Allow AATTstaticmethod decorator to declare static cdef methods. This is especially useful for declaring \"constructors\" for cdef classes that can take non-Python arguments.
* Taking a ``char
*`` from a temporary Python string object is safer in more cases and can be done inside of non-trivial expressions, including arguments of a function call. A compile time error is raised only when such a pointer is assigned to a variable and would thus exceed the lifetime of the string itself.
* Generators have new properties ``__name__`` and ``__qualname__`` that provide the plain/qualified name of the generator function (following CPython 3.5). See http://bugs.python.org/issue21205
* The ``inline`` function modifier is available as a decorator ``AATTcython.inline`` in pure mode.
* When cygdb is run in a virtualenv, it enables the same virtualenv inside of the debugger. Patch by Marc Abramowitz.
* PEP 465: dedicated infix operator for matrix multiplication (A AATT B).
* HTML output of annotated code uses Pygments for code highlighting and generally received a major overhaul by Matthias Bussonier.
* IPython magic support is now available directly from Cython with the command \"%load_ext cython\". Cython code can directly be executed in a cell when marked with \"%%cython\". Code analysis is available with \"%%cython -a\". Patch by Martín Gaitán.
* Simple support for declaring Python object types in Python signature annotations. Currently requires setting the compiler directive ``annotation_typing=True``.
* New directive ``use_switch`` (defaults to True) to optionally disable the optimization of chained if statement to C switch statements.
* Defines dynamic_cast et al. in ``libcpp.cast`` and C++ heap data structure operations in ``libcpp.algorithm``.
* Shipped header declarations in ``posix.
*`` were extended to cover more of the POSIX API. Patches by Lars Buitinck and Mark Peek.
* Optimizations
* Simple calls to C implemented Python functions/methods are faster. This also speeds up many operations on builtins that Cython cannot otherwise optimise.
* The \"and\"/\"or\" operators try to avoid unnecessary coercions of their arguments. They now evaluate the truth value of each argument independently and only coerce the final result of the whole expression to the target type (e.g. the type on the left side of an assignment). This also avoids reference counting overhead for Python values during evaluation and generally improves the code flow in the generated C code.
* The Python expression \"2
*
* N\" is optimised into bit shifting. See http://bugs.python.org/issue21420
* Cascaded assignments (a = b = ...) try to minimise the number of type coercions.
* Calls to ``slice()`` are translated to a straight C-API call.
* Bugs fixed
* Crash when assigning memory views from ternary conditional expressions.
* Nested C++ templates could lead to unseparated \">>\" characters being generated into the C++ declarations, which older C++ compilers could not parse.
* Sending SIGINT (Ctrl-C) during parallel cythonize() builds could hang the child processes.
* No longer ignore local setup.cfg files for distutils in pyximport. Patch by Martin Teichmann.
* Taking a ``char
*`` from an indexed Python string generated unsafe reference counting code.
* Set literals now create all of their items before trying to add them to the set, following the behaviour in CPython. This makes a difference in the rare case that the item creation has side effects and some items are not hashable (or if hashing them has side effects, too).
* Cython no longer generates the cross product of C functions for code that uses memory views of fused types in function signatures (e.g. ``cdef func(floating[:] a, floating[:] b)``). This is considered the expected behaviour by most users and was previously inconsistent with other structured types like C arrays. Code that really wants all type combinations can create the same fused memoryview type under different names and use those in the signature to make it clear which types are independent.
* Names that were unknown at compile time were looked up as builtins at runtime but not as global module names. Trying both lookups helps with globals() manipulation.
* Fixed stl container conversion for typedef element types.
* ``obj.pop(x)`` truncated large C integer values of x to ``Py_ssize_t``.
* ``__init__.pyc`` is recognised as marking a package directory (in addition to .py, .pyx and .pxd).
* Syntax highlighting in ``cython-mode.el`` for Emacs no longer incorrectly highlights keywords found as part of longer names.
* Correctly handle ``from cython.submodule cimport name``.
* Fix infinite recursion when using super with cpdef methods.
* No-args ``dir()`` was not guaranteed to return a sorted list.
* Other changes
* The header line in the generated C files no longer contains the timestamp but only the Cython version that wrote it. This was changed to make builds more reproducible.
* Removed support for CPython 2.4, 2.5 and 3.1.
* The licensing implications on the generated code were clarified to avoid legal constraints for users.
* Thu Jul 31 2014 dimstarAATTopensuse.org- Rename rpmlintrc to %{name}-rpmlintrc. Follow the packaging guidelines.
* Thu Jul 24 2014 mciharAATTsuse.cz- Update to version 0.20.2:
* Some optimisations for set/frozenset instantiation.
* Support for C++ unordered_set and unordered_map.
* Access to attributes of optimised builtin methods (e.g. ``[].append.__name__``) could fail to compile.
* Memory leak when extension subtypes add a memory view as attribute to those of the parent type without having Python object attributes or a user provided dealloc method.
* Compiler crash on readonly properties in \"binding\" mode.
* Auto-encoding with ``c_string_encoding=ascii`` failed in Py3.3.
* Crash when subtyping freelist enabled Cython extension types with Python classes that use ``__slots__``.
* Freelist usage is restricted to CPython to avoid problems with other Python implementations.
* Memory leak in memory views when copying overlapping, contiguous slices.
* Format checking when requesting non-contiguous buffers from ``cython.array`` objects was disabled in Py3.
* C++ destructor calls in extension types could fail to compile in clang.
* Buffer format validation failed for sequences of strings in structs.
* Docstrings on extension type attributes in .pxd files were rejected.- add python-xml to build requirements for testsuite
* Thu May 08 2014 toddrme2178AATTgmail.com- Update to version 0.20.1
* List/Tuple literals multiplied by more than one factor were only multiplied by the last factor instead of all.
* Lookups of special methods (specifically for context managers) could fail in Python <= 2.6/3.1.
* Local variables were erroneously appended to the signature introspection of Cython implemented functions with keyword-only arguments under Python 3.
* In-place assignments to variables with inferred Python builtin/extension types could fail with type errors if the result value type was incompatible with the type of the previous value.
* The C code generation order of cdef classes, closures, helper code, etc. was not deterministic, thus leading to high code churn.
* Type inference could fail to deduce C enum types.
* Type inference could deduce unsafe or inefficient types from integer assignments within a mix of inferred Python variables and integer variables.
* Mon Feb 03 2014 jengelhAATTinai.de- Cython grew a dependency on saxutils (and since then, libplist failed to build). Add python-xml as a Requires to avoid: [...] File \"/usr/lib64/python2.7/site-packages/Cython/Compiler/Annotate.py\", line 6, in from xml.sax.saxutils import escape as html_escape. ImportError: No module named xml.sax.saxutils
* Fri Jan 31 2014 speilickeAATTsuse.com- 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).
* The new extension type decorator AATTcython.no_gc_clear prevents objects from being cleared during cyclic garbage collection, thus making sure that object attributes are kept alive until deallocation.
* During cyclic garbage collection, attributes of extension types that cannot create reference cycles due to their type (e.g. strings) are no longer considered for traversal or clearing. This can reduce the processing overhead when searching for or cleaning up reference cycles.
* Package compilation (i.e. __init__.py files) now works, starting with Python 3.3.
* The cython-mode.el script for Emacs was updated. Patch by Ivan Andrus.
* An option common_utility_include_dir was added to cythonize() to save oft-used utility code once in a separate directory rather than as part of each generated file.
* unraisable_tracebacks directive added to control printing of tracebacks of unraisable exceptions.
* Mon Oct 21 2013 dmuellerAATTsuse.com- 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.
* Fri Oct 11 2013 p.drouandAATTgmail.com- Implement update-alternatives
* Mon May 13 2013 dmuellerAATTsuse.com- 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.
