- 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).
* Fixed or silenced many Clang warnings.
* Fixes bug with powers of pure real complex numbers (Github issue #1538).

* Fixes bug with ``cython.view.array`` missing utility code in some cases
(Github issue #1502).
+ Other changes

- 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
-------------------------------------------------------------------
Mon Feb 1 10:30:06 UTC 2016 - toddrme2178@gmail.com
- update to version 0.23.4:
* Memory leak when calling Python functions in PyPy.
* Compilation problem with MSVC in C99-ish mode.
* Warning about unused values in a helper macro.
- update to version 0.23.3:
* Invalid C code for some builtin methods. This fixes ticket 856
again.
* Incorrect C code in helper functions for PyLong conversion and
string decoding. This fixes ticket 863, ticket 864 and ticket
865. Original patch by Nikolaus Rath.
* Large folded or inserted integer constants could use too small C
integer types and thus trigger a value wrap-around.
* The coroutine and generator types of Cython now also register
directly with the Coroutine and Generator ABCs in the
backports_abc module if it can be imported. This fixes ticket 870.
- update to version 0.23.2:
* Compiler crash when analysing some optimised expressions.
* Coverage plugin was adapted to coverage.py 4.0 beta 2.
* C++ destructor calls could fail when '&' operator is overwritten.
* Incorrect C literal generation for large integers in compile-time
evaluated DEF expressions and constant folded expressions.
* Byte string constants could end up as Unicode strings when
originating from compile-time evaluated DEF expressions.
* Invalid C code when caching known builtin methods. This fixes
ticket 860.
* ino_t in posix.types was not declared as unsigned.
* Declarations in libcpp/memory.pxd were missing operator!(). Patch
by Leo Razoumov.
* Static cdef methods can now be declared in .pxd files.
- update to version 0.23.1:
* Invalid C code for generators. This fixes ticket 858.
* Invalid C code for some builtin methods. This fixes ticket 856.
* Invalid C code for unused local buffer variables. This fixes
ticket 154.
* Test failures on 32bit systems. This fixes ticket 857.
* Code that uses "from xyz import *" and global C struct/union/array
variables could fail to compile due to missing helper
functions. This fixes ticket 851.
* Misnamed PEP 492 coroutine property cr_yieldfrom renamed to
cr_await to match CPython.
* Missing deallocation code for C++ object attributes in certain
extension class hierarchies.
* Crash when async coroutine was not awaited.
* Compiler crash on yield in signature annotations and default
argument values. Both are forbidden now.
* Compiler crash on certain constructs in finally clauses.
* Cython failed to build when CPython's pgen is installed.
- update to version 0.23:
* Features added
+ PEP 492 (async/await) was implemented. See
https://www.python.org/dev/peps/pep-0492/
+ PEP 448 (Additional Unpacking Generalizations) was
implemented. See https://www.python.org/dev/peps/pep-0448/
+ Support for coverage.py 4.0+ can be enabled by adding the plugin
"Cython.Coverage" to the ".coveragerc" config file.
+ Annotated HTML source pages can integrate (XML) coverage
reports.
+ Tracing is supported in nogil functions/sections and module init
code.
+ When generators are used in a Cython module and the module
imports the modules "inspect" and/or "asyncio", Cython enables
interoperability by patching these modules during the import to
recognise Cython's internal generator and coroutine types. This
can be disabled by C compiling the module with "-D
CYTHON_PATCH_ASYNCIO=0" or "-D CYTHON_PATCH_INSPECT=0"
+ When generators or coroutines are used in a Cython module, their
types are registered with the Generator and Coroutine ABCs in
the collections or collections.abc stdlib module at import time
to enable interoperability with code that needs to detect and
process Python generators/coroutines. These ABCs were added in
CPython 3.5 and are available for older Python versions through
the backports_abc module on PyPI. See
https://bugs.python.org/issue24018
+ Adding/subtracting/dividing/modulus and equality comparisons
with constant Python floats and small integers are faster.
+ Binary and/or/xor/rshift operations with small constant Python
integers are faster.
+ When called on generator expressions, the builtins all(), any(),
dict(), list(), set(), sorted() and unicode.join() avoid the
generator iteration overhead by inlining a part of their
functionality into the for-loop.
+ Keyword argument dicts are no longer copied on function entry
when they are not being used or only passed through to other
function calls (e.g. in wrapper functions).
+ The PyTypeObject declaration in cpython.object was extended.
+ The builtin type type is now declared as PyTypeObject in source,
allowing for extern functions taking type parameters to have the
correct C signatures. Note that this might break code that uses
type just for passing around Python types in typed
variables. Removing the type declaration provides a backwards
compatible fix.
+ wraparound() and boundscheck() are available as no-ops in pure
Python mode.
+ Const iterators were added to the provided C++ STL declarations.
+ Smart pointers were added to the provided C++ STL
declarations. Patch by Daniel Filonik.
+ NULL is allowed as default argument when embedding
signatures. This fixes ticket 843.
+ When compiling with --embed, the internal module name is changed
to __main__ to allow arbitrary program names, including those
that would be invalid for modules. Note that this prevents reuse
of the generated C code as an importable module.
+ External C++ classes that overload the assignment operator can
be used. Patch by Ian Henriksen.
+ Support operator bool() for C++ classes so they can be used in
if statements.
* Bugs fixed
+ Calling "yield from" from Python on a Cython generator that
returned a value triggered a crash in CPython. This is now being
worked around. See https://bugs.python.org/issue23996
+ Language level 3 did not enable true division (a.k.a. float
division) for integer operands.
+ Functions with fused argument types that included a generic
'object' fallback could end up using that fallback also for
other explicitly listed object types.
+ Relative cimports could accidentally fall back to trying an
absolute cimport on failure.
+ The result of calling a C struct constructor no longer requires
an intermediate assignment when coercing to a Python dict.
+ C++ exception declarations with mapping functions could fail to
compile when pre-declared in .pxd files.
+ cpdef void methods are now permitted.
+ abs(cint) could fail to compile in MSVC and used sub-optimal
code in C++. Patch by David Vierra, original patch by Michael
Enßlin.
+ Buffer index calculations using index variables with small C
integer types could overflow for large buffer sizes. Original
patch by David Vierra.
+ C unions use a saner way to coerce from and to Python dicts.
+ When compiling a module foo.pyx, the directories in sys.path are
no longer searched when looking for foo.pxd. Patch by Jeroen
Demeyer.
+ Memory leaks in the embedding main function were fixed. Original
patch by Michael Enßlin.
+ Some complex Python expressions could fail to compile inside of
finally clauses.
+ Unprefixed 'str' literals were not supported as C varargs
arguments.
+ Fixed type errors in conversion enum types to/from Python. Note
that this imposes stricter correctness requirements on enum
declarations.
* Other changes
+ Changed mangling scheme in header files generated by cdef api
declarations.
+ Installation under CPython 3.3+ no longer requires a pass of the
2to3 tool. This also makes it possible to run Cython in Python
3.3+ from a source checkout without installing it first. Patch
by Petr Viktorin.
+ jedi-typer.py (in Tools/) was extended and renamed to
jedityper.py (to make it importable) and now works with and
requires Jedi 0.9. Patch by Tzer-jen Wei.

-------------------------------------------------------------------
Wed Apr 22 09:10:30 UTC 2015 - mcihar@suse.cz
- Update to 0.22:
Features added
* C functions can coerce to Python functions, which allows passing them
around as callable objects.
* C arrays can be assigned by value and auto-coerce from Python iterables
and to Python lists (and tuples).
* Extern C functions can now be declared as cpdef to export them to
the module's Python namespace. Extern C functions in pxd files export
their values to their own module, iff it exists.
* Anonymous C tuple types can be declared as (ctype1, ctype2, ...).
* PEP 479: turn accidental StopIteration exceptions that exit generators
into a RuntimeError, activated with future import "generator_stop".
See http://legacy.python.org/dev/peps/pep-0479/
* Looping over ``reversed(range())`` is optimised in the same way as
``range()``. Patch by Favian Contreras.
Bugs fixed
* Mismatching 'except' declarations on signatures in .pxd and .pyx files failed
to produce a compile error.
* Failure to find any files for the path pattern(s) passed into ``cythonize()``
is now an error to more easily detect accidental typos.
* The ``logaddexp`` family of functions in ``numpy.math`` now has correct
declarations.
* In Py2.6/7 and Py3.2, simple Cython memory views could accidentally be
interpreted as non-contiguous by CPython, which could trigger a CPython
bug when copying data from them, thus leading to data corruption.
See CPython issues 12834 and 23349.
Other changes
* Preliminary support for defining the Cython language with a formal grammar.
To try parsing your files against this grammar, use the --formal_grammar directive.
Experimental.
* ``_`` is no longer considered a cacheable builtin as it could interfere with
gettext.
* Cythonize-computed metadata now cached in the generated C files.

- Improve update-alternatives.
- Remove Cython-fix-version-detection.patch
(got fixed upstream)
- update to version 0.21.1:
* Features added
- New cythonize option -a to generate the annotated HTML source view.
- Missing C-API declarations in cpython.unicode were added.
- Passing language='c++' into cythonize() globally enables C++ mode
for all modules that were not passed as Extension objects
(i.e. only source files and file patterns).
- Py_hash_t is a known type (used in CPython for hash values).
- PySlice_*() C-API functions are available from the cpython.slice module.
- Allow arrays of C++ classes.
* Bugs fixed
- Reference leak for non-simple Python expressions in boolean and/or expressions.
- To fix a name collision and to reflect availability on host
platforms, standard C declarations [ clock(), time(), struct tm
and tm* functions ] were moved from posix/time.pxd to a new
libc/time.pxd. Patch by Charles Blake.
- Rerunning unmodified modules in IPython's cython support
failed. Patch by Matthias Bussonier.
- Casting C++ std::string to Python byte strings failed when
auto-decoding was enabled.
- Fatal exceptions in global module init code could lead to
crashes if the already created module was used later on
(e.g. through a stale reference in sys.modules or elsewhere).
- cythonize.py script was not installed on MS-Windows.
* Other changes
- Compilation no longer fails hard when unknown compilation
options are passed. Instead, it raises a warning and ignores
them (as it did silently before 0.21). This will be changed back
to an error in a future release.

Fri Sep 12 10:52:18 UTC 2014 - toddrme2178@gmail.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

- 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 http://bugs.python.org/issue21205
* 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
``annotation_typing=True``.
* New directive ``use_switch`` (defaults to True) to optionally disable
the optimization of chained if statement to C switch statements.
* Defines dynamic_cast et al. in ``libcpp.cast`` and C++ heap data
structure operations in ``libcpp.algorithm``.
* Shipped header declarations in ``posix.*`` were extended to cover
more of the POSIX API. Patches by Lars Buitinck and Mark Peek.
* Optimizations
* Simple calls to C implemented Python functions/methods are faster.
This also speeds up many operations on builtins that Cython cannot
otherwise optimise.
* The "and"/"or" operators try to avoid unnecessary coercions of their
arguments. They now evaluate the truth value of each argument
independently and only coerce the final result of the whole expression
to the target type (e.g. the type on the left side of an assignment).
This also avoids reference counting overhead for Python values during
evaluation and generally improves the code flow in the generated C code.
* The Python expression "2 ** N" is optimised into bit shifting.
See http://bugs.python.org/issue21420
* Cascaded assignments (a = b = ...) try to minimise the number of
type coercions.
* Calls to ``slice()`` are translated to a straight C-API call.
* Bugs fixed
* Crash when assigning memory views from ternary conditional expressions.
* Nested C++ templates could lead to unseparated ">>" characters being
generated into the C++ declarations, which older C++ compilers could
not parse.
* Sending SIGINT (Ctrl-C) during parallel cythonize() builds could
hang the child processes.
* No longer ignore local setup.cfg files for distutils in pyximport.
Patch by Martin Teichmann.
* Taking a ``char*`` from an indexed Python string generated unsafe
reference counting code.
* Set literals now create all of their items before trying to add them
to the set, following the behaviour in CPython. This makes a
difference in the rare case that the item creation has side effects
and some items are not hashable (or if hashing them has side effects,
too).
* Cython no longer generates the cross product of C functions for code
that uses memory views of fused types in function signatures (e.g.
``cdef func(floating[:] a, floating[:] b)``). This is considered the
expected behaviour by most users and was previously inconsistent with
other structured types like C arrays. Code that really wants all type
combinations can create the same fused memoryview type under different
names and use those in the signature to make it clear which types are
independent.
* Names that were unknown at compile time were looked up as builtins at
runtime but not as global module names. Trying both lookups helps with
globals() manipulation.
* Fixed stl container conversion for typedef element types.
* ``obj.pop(x)`` truncated large C integer values of x to ``Py_ssize_t``.
* ``__init__.pyc`` is recognised as marking a package directory
(in addition to .py, .pyx and .pxd).
* Syntax highlighting in ``cython-mode.el`` for Emacs no longer
incorrectly highlights keywords found as part of longer names.
* Correctly handle ``from cython.submodule cimport name``.
* Fix infinite recursion when using super with cpdef methods.
* No-args ``dir()`` was not guaranteed to return a sorted list.
* Other changes
* The header line in the generated C files no longer contains the
timestamp but only the Cython version that wrote it. This was
changed to make builds more reproducible.
* Removed support for CPython 2.4, 2.5 and 3.1.
* The licensing implications on the generated code were clarified
to avoid legal constraints for users.

Thu Jul 31 16:26:07 UTC 2014 - dimstar@opensuse.org
- Rename rpmlintrc to %{name}-rpmlintrc.
Follow the packaging guidelines.
-------------------------------------------------------------------
Thu Jul 24 05:32:47 UTC 2014 - mcihar@suse.cz
- Update to version 0.20.2:
* Some optimisations for set/frozenset instantiation.
* Support for C++ unordered_set and unordered_map.
* Access to attributes of optimised builtin methods (e.g.
``[].append.__name__``) could fail to compile.
* Memory leak when extension subtypes add a memory view as attribute
to those of the parent type without having Python object attributes
or a user provided dealloc method.
* Compiler crash on readonly properties in "binding" mode.
* Auto-encoding with ``c_string_encoding=ascii`` failed in Py3.3.
* Crash when subtyping freelist enabled Cython extension types with
Python classes that use ``__slots__``.
* Freelist usage is restricted to CPython to avoid problems with other
Python implementations.
* Memory leak in memory views when copying overlapping, contiguous slices.
* Format checking when requesting non-contiguous buffers from
``cython.array`` objects was disabled in Py3.
* C++ destructor calls in extension types could fail to compile in clang.
* Buffer format validation failed for sequences of strings in structs.
* Docstrings on extension type attributes in .pxd files were rejected.
- add python-xml to build requirements for testsuite
-------------------------------------------------------------------
Thu May 8 11:40:51 UTC 2014 - toddrme2178@gmail.com
- Update to version 0.20.1
* List/Tuple literals multiplied by more than one factor were only multiplied
by the last factor instead of all.
* Lookups of special methods (specifically for context managers) could fail
in Python <= 2.6/3.1.
* Local variables were erroneously appended to the signature introspection
of Cython implemented functions with keyword-only arguments under Python 3.
* In-place assignments to variables with inferred Python builtin/extension
types could fail with type errors if the result value type was incompatible
with the type of the previous value.
* The C code generation order of cdef classes, closures, helper code,
etc. was not deterministic, thus leading to high code churn.
* Type inference could fail to deduce C enum types.
* Type inference could deduce unsafe or inefficient types from integer
assignments within a mix of inferred Python variables and integer
variables.
-------------------------------------------------------------------
Mon Feb 3 18:51:50 UTC 2014 - jengelh@inai.de
- Cython grew a dependency on saxutils (and since then, libplist
failed to build). Add python-xml as a Requires to avoid:
[...]
File "/usr/lib64/python2.7/site-packages/Cython/Compiler/Annotate.py",
line 6, in <module> from xml.sax.saxutils import escape as
html_escape.
ImportError: No module named xml.sax.saxutils
-------------------------------------------------------------------
Fri Jan 31 10:19:40 UTC 2014 - speilicke@suse.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 @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. __init__.py files) now works, starting
with Python 3.3.
* The cython-mode.el script for Emacs was updated. Patch by Ivan Andrus.
* An option common_utility_include_dir was added to cythonize() to save
oft-used utility code once in a separate directory rather than as
part of each generated file.
* unraisable_tracebacks directive added to control printing of
tracebacks of unraisable exceptions.
-------------------------------------------------------------------
Mon Oct 21 12:13:57 UTC 2013 - dmueller@suse.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.

- Implement update-alternatives
-------------------------------------------------------------------
Mon May 13 08:17:40 UTC 2013 - dmueller@suse.com
- update to 0.19.1:
* Completely empty C-API structs for extension type slots (protocols like
number/mapping/sequence) are no longer generated into the C code.
* Docstrings that directly follow a public/readonly attribute declaration
in a cdef class will be used as docstring of the auto-generated property.
This fixes ticket 206.
* The automatic signature documentation tries to preserve more semantics
of default arguments and argument types. Specifically, bint arguments
now appear as type bool.
* A warning is emitted when negative literal indices are found inside of
a code section that disables wraparound handling. This helps with
fixing invalid code that might fail in the face of future compiler
optimisations.
* Constant folding for boolean expressions (and/or) was improved.
* Added a build_dir option to cythonize() which allows one to place
the generated .c files outside the source tree.
