|

|
||||
- 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.

|
||||
|
||||
- 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.
