python-Cython-doc-0.27.3-bp152.2.1

- Disable tests as they randomly fail while it can't be triggered
  when reproducing localy

- update to 0.27.3
  * see CHANGES.txt for details
- Disable abs test wrt upstream issue with new GCC versions:
  * https://github.com/cython/cython/issues/1911

- Update to 0.26.1
  + Bugs fixed
  * ``cython.view.array`` was missing ``.__len__()``.
  * Extension types with a ``.pxd`` override for their ``__releasebuffer__`` slot
    (e.g. as provided by Cython for the Python ``array.array`` type) could leak
    a reference to the buffer owner on release, thus not freeing the memory.
    (Github issue #1638)
  * Auto-decoding failed in 0.26 for strings inside of C++ containers.
    (Github issue #1790)
  * Compile error when inheriting from C++ container types.
    (Github issue #1788)
  * Invalid C code in generators (declaration after code).
    (Github issue #1801)
  * Arithmetic operations on ``const`` integer variables could generate invalid code.
    (Github issue #1798)
  * Local variables with names of special Python methods failed to compile inside of
    closures. (Github issue #1797)
  * Problem with indirect Emacs buffers in cython-mode.
    Patch by Martin Albrecht (Github issue #1743).
  * Extension types named ``result`` or ``PickleError`` generated invalid unpickling code.
    Patch by Jason Madden (Github issue #1786).
  * Bazel integration failed to compile ``.py`` files.
    Patch by Guro Bokum (Github issue #1784).
  * Some include directories and dependencies were referenced with their absolute paths
    in the generated files despite lying within the project directory.
  * Failure to compile in Py3.7 due to a modified signature of ``_PyCFunctionFast()``
- Update to 0.26
  + Features added
  * Pythran can be used as a backend for evaluating NumPy array expressions.
    Patch by Adrien Guinet (Github issue #1607).
  * cdef classes now support pickling by default when possible.
    This can be disabled with the ``auto_pickle`` directive.
  * Speed up comparisons of strings if their hash value is available.
    Patch by Claudio Freire (Github issue #1571).
  * Support pyximport from zip files.
    Patch by Sergei Lebedev (Github issue #1485).
  * IPython magic now respects the ``__all__`` variable and ignores
    names with leading-underscore (like ``import *`` does).
    Patch by Syrtis Major (Github issue #1625).
  * ``abs()`` is optimised for C complex numbers.
    Patch by da-woods (Github issue #1648).
  * The display of C lines in Cython tracebacks can now be enabled at runtime
    via ``import cython_runtime; cython_runtime.cline_in_traceback=True``.
    The default has been changed to False.
  * The overhead of calling fused types generic functions was reduced.
  * "cdef extern" include files are now also searched relative to the current file.
    Patch by Jeroen Demeyer (Github issue #1654).
  * Optional optimization for re-aquiring the GIL, controlled by the
    `fast_gil` directive.
  + Bugs fixed
  * Item lookup/assignment with a unicode character as index that is typed
    (explicitly or implicitly) as ``Py_UCS4`` or ``Py_UNICODE`` used the
    integer value instead of the Unicode string value. Code that relied on
    the previous behaviour now triggers a warning that can be disabled by
    applying an explicit cast. (Github issue #1602)
  * f-string processing was adapted to changes in PEP 498 and CPython 3.6.
  * Invalid C code when decoding from UTF-16(LE/BE) byte strings.
    (Github issue #1696)
  * Unicode escapes in 'ur' raw-unicode strings were not resolved in Py2 code.
    Original patch by Aaron Gallagher (Github issue #1594).
  * File paths of code objects are now relative.
    Original patch by Jelmer Vernooij (Github issue #1565).
  * Decorators of cdef class methods could be executed twice.
    Patch by Jeroen Demeyer (Github issue #1724).
  * Dict iteration using the Py2 ``iter*`` methods failed in PyPy3.
    Patch by Armin Rigo (Github issue #1631).
  * Several warnings in the generated code are now suppressed.
  + Other changes
  * The ``unraisable_tracebacks`` option now defaults to ``True``.
  * Coercion of C++ containers to Python is no longer automatic on attribute
    access (Github issue #1521).
  * Access to Python attributes of cimported modules without the corresponding
    import is now a compile-time (rather than runtime) error.
  * Do not use special dll linkage for "cdef public" functions.
    Patch by Jeroen Demeyer (Github issue #1687).
  * cdef/cpdef methods must match their declarations.  See Github Issue #1732.
    This is now a warning and will be an error in future releases.
- Update to 0.25.2
  + Bugs fixed
  * Fixes several issues with C++ template deduction.
  * Fixes a issue with bound method type inference (Github issue #551).
  * Fixes a bug with cascaded tuple assignment (Github issue #1523).

- Create subpackage for documentation

- Ensure neutrality of description.

- update for multipython build

- Update to version 0.25.1
  + Bugs fixed
  * Fixes a bug with ``isinstance(o, Exception)`` (Github issue #1496).
  * Fixes bug with ``cython.view.array`` missing utility code in some cases
    (Github issue #1502).
  + Other changes
  * The distutils extension ``Cython.Distutils.build_ext`` has been reverted,
    temporarily, to be ``old_build_ext`` to give projects time to migrate.
    The new build_ext is available as ``new_build_ext``.

- Fix source URL.

- 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.
  * 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
    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.
    + @property 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

- 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.

- Update to 0.22.1:
  Bugs fixed
  * 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.
  * Tracing exception handling code could enter the trace function with an
    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.

    Xcode versions.
  * C compilation could fail in pypy3.
  * Fixed a memory leak in the compiler when compiling multiple modules.

    leak into later compiler runs.  Fix by Jeroen Demeyer.  This fixes
    ticket 845.
- removed patch fix-32bit.patch as applied upstream

- Use Source URL from cython.org

- Add python-numpy as BuildRequires to have more complete test coverage

- Fix doctests in 32-bit environment (fix-32bit.patch)

- 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/

    ``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.
