- "mangle" tests/run/cpdef_extern_func.pyx to allow package to build
  for SLE_11_SP3 and SLE_11_SP4.
  * cpdef const char* strchr(const char *haystack, int needle);
    does not seem to match any from /usr/include/string.h
    and fails for cpp tests via python -vv
  * cpdef_extern_func.pyx was not present in 0.21.1

  * fixing update_alternatives

Fri Jul 10 21:59:38 UTC 2015 -

- 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.
  * Using ``const`` C++ references in intermediate parts of longer
    expressions could fail to compile.
  * C++ exception declarations with mapping functions could fail to compile
    when pre-declared in .pxd files.
  * 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.

Wed Apr 22 09:10:30 UTC 2015 -

- 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".
  * 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.

Fri Jan  9 15:20:31 UTC 2015 -

- Re-enable test-suite.
- Add gcc-c++ BuildRequires: needed for the test-suite to be able
  to pass.

Thu Jan  8 12:22:10 UTC 2015 -

- Fix usage of update-alternatives.

Thu Dec 18 10:48:28 UTC 2014 -

- 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).
    - 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.

- fix bashisms in pre script

Fri Sep 12 10:52:18 UTC 2014 -

- 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-bcolz/python3-bcolz is an example of another package

Thu Sep 11 09:30:20 UTC 2014 -

- 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 @staticmethod 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
    * The ``inline`` function modifier is available as a decorator
      ``@cython.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 @ 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
    * 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.
    * 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,
    * 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
    * 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 16:26:07 UTC 2014 -

- Rename rpmlintrc to %{name}-rpmlintrc.
  Follow the packaging guidelines.

Thu Jul 24 05:32:47 UTC 2014 -

- 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  8 11:40:51 UTC 2014 -

- 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

Mon Feb  3 18:51:50 UTC 2014 -

- 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/",
  line 6, in <module> from xml.sax.saxutils import escape as
  ImportError: No module named xml.sax.saxutils

Fri Jan 31 10:19:40 UTC 2014 -

- 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 @cython.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. 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 12:13:57 UTC 2013 -

- 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

    * 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 17:06:20 UTC 2013 -

- Implement update-alternatives

Mon May 13 08:17:40 UTC 2013 -

- 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
  * 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.
