Changelog for python3-Cython-0.21-1.1.x86_64.rpm :

* 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.- Update to 0.20.2 (2014-06-16)
* Features added
* Some optimisations for set/frozenset instantiation.
* Support for C++ unordered_set and unordered_map.
* Bugs fixed
* 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 accidentally omitted 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.
* Thu Jul 31 2014 dimstarAATTopensuse.org- Rename rpmlintrc to %{name}-rpmlintrc. Follow the packaging guidelines.
* 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.
* Tue Feb 04 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.
* Tue Oct 22 2013 toddrme2178AATTgmail.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.
