python3-Cython-0.29.14-lp152.2.6.1 RPM for i586

From OpenSuSE Leap 15.2 updates for i586

Name: python3-Cython Distribution: openSUSE Leap 15.2
Version: 0.29.14 Vendor: openSUSE
Release: lp152.2.6.1 Build date: Thu Jun 24 14:13:46 2021
Group: Unspecified Build host: build81
Size: 10806665 Source RPM: python-Cython-0.29.14-lp152.2.6.1.src.rpm
Summary: The Cython compiler for writing C extensions for the Python language
The Cython language allows for writing C extensions for the Python
language. Cython is a source code translator based on Pyrex, but
supports more cutting edge functionality and optimizations.

The Cython language is very close to the Python language (and most Python
code is also valid Cython code), but Cython additionally supports calling C
functions and declaring C types on variables and class attributes. This
allows the compiler to generate very efficient C code from Cython code.

      + The generated code failed to initialise the tp_print slot in
      CPython 3.8. 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. (Github issue #3108)
      + Error reports in the Jupyter notebook showed unhelpful stack
      traces. Patch by Matthew Edwards (Github issue #3196).
      + Python.h is now also included explicitly from public header
      files. (Github issue #3133).
      + Distutils builds with --parallel did not work when using
      Cython's deprecated build_ext command. Patch by Alphadelta14
      (Github issue #3187).
    * Other changes
      + The PyMemoryView_*() C-API is available in
      cpython.memoryview. Patch by Nathan Manville. (Github issue
* Fri Jul 26 2019 Matej Cepl <>
  - Update to 0.29.13:
    - A reference leak for None was fixed when converting
      a memoryview to a Python object. (Github issue #3023)
    - The declaration of PyGILState_STATE in cpython.pystate was
      unusable. Patch by Kirill Smelkov. (Github issue #2997)
    - The declarations in posix.mman were extended. Patches by
      Kirill Smelkov. (Github issues #2893, #2894, #3012)
* Sun Jul 21 2019 Arun Persaud <>

* Sat Jul 06 2019 Arun Persaud <>
  - update to version 0.29.11:
    * Bugs fixed

      + 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).

      Cython module reports an exceptions. Cython now makes sure it keeps
      an owned reference to the module
    * Resolved a C89 compilation problem when enabling the fast-gil sharing feature.
    * Coverage reporting did not include the signature line of cdef functions
    * Casting a GIL-requiring function into a nogil function now issues a warning
    * Generators and coroutines were missing their return type annotation
* Tue Apr 02 2019 Todd R <>

    The pngmath Sphinx extension has been removed.  Use imgmath instead.
    See: gh#cython/cython#2818
* Thu Feb 28 2019 Ondřej Súkup <>
  - update to 0.29.6
    * Fix a crash when accessing the __kwdefaults__ special attribute of fused functions.
    * Fix the parsing of buffer format strings that contain numeric sizes, which
      could lead to incorrect input rejections.
    * Avoid a C #pragma in old gcc versions that was only added in GCC 4.6.
    * Auto-encoding of Unicode strings to UTF-8 C/C++ strings failed in Python 3,

  - 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)

    * A C compiler warning about an invalid safety check was
      resolved. (Github issue #2731)
* Thu Dec 06 2018
  - revert to version 0.28.5 to restore support for subinterpreters
    needed by Ceph - stopgap measure until issue can be addressed
    upstream (bsc#1118611)
* 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)
      + @cython.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
      + (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
      + 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,
      + 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 @cfunc
      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
      + 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
  - 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
  - update to version 0.28.4:
    * Bugs fixed
      + Reallowing tp_clear() in a subtype of an @no_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
  - 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
  - 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
  - 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
  - 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 @cython.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
      + 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)
      + was not accepted on Python classes with an
      @cython.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
  - 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 (
    * 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 and related issues.
    * The new METH_FASTCALL calling convention for PyCFunctions is supported
      in CPython 3.6.  See
    * C++ classes can now have typedef members. STL containers updated with
    * Support for bazel using a the pyx_library rule in //Tools:rules.bzl.
    * Initial support for using Cython modules in Pyston.  Patch by Daetalus.
    * Dynamic Python attributes are allowed on cdef classes if an attribute
      ``cdef dict __dict__`` is declared in the class.  Patch by empyrical.
    * Cython implemented C++ classes can make direct calls to base class methods.
      Patch by empyrical.
    * New directive ``cython.no_gc`` to fully disable GC for a cdef class.
      Patch by Claudio Freire.
    * Buffer variables are no longer excluded from ``locals()``.
      Patch by da-woods.
    * 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
    * 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
  - update to version 0.24:
    * Features added
      + PEP 498: Literal String Formatting (f-strings). Original patch
      by Jelle Zijlstra.
      + PEP 515: Underscores as visual separators in number
      + Parser was adapted to some minor syntax changes in Py3.6,
      + The embedded C code comments that show the original source code
      can be discarded with the new directive
      + Cpdef enums are now first-class iterable, callable types in
      + 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.
      + @property syntax fully supported in cdef classes, old syntax
      + C++ classes can now be declared with default template
    * 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
      + 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
    * Return values of async functions could be ignored and replaced by
    * 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
    * 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
  - 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
    * 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 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
      + PEP 448 (Additional Unpacking Generalizations) was
      implemented. See
      + Support for 4.0+ can be enabled by adding the plugin
      "Cython.Coverage" to the ".coveragerc" config file.
      + Annotated HTML source pages can integrate (XML) coverage
      + Tracing is supported in nogil functions/sections and module init
      + 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
      + When generators or coroutines are used in a Cython module, their
      types are registered with the Generator and Coroutine ABCs in
      the collections or 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
      + 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
      + 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
      + 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
      + 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
      + Fixed type errors in conversion enum types to/from Python. Note
      that this imposes stricter correctness requirements on enum
    * Other changes
      + Changed mangling scheme in header files generated by cdef api
      + 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.
      + (in Tools/) was extended and renamed to (to make it importable) and now works with and
      requires Jedi 0.9. Patch by Tzer-jen Wei.

      active exception set.
    * 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.

      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".
    * 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
    * 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.
    * ``_`` is no longer considered a cacheable builtin as it could interfere with
    * Cythonize-computed metadata now cached in the generated C files.

      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).
    - 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.
