./devel/py-cython, C-Extensions for Python

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 0.25.2, Package name: py27-cython-0.25.2, Maintainer: pkgsrc-users

The Cython language makes writing C extensions for the Python language
as easy as Python itself. Cython is a source code translator based on
the well-known Pyrex, but supports more cutting edge functionality and

The Cython language is very close to the Python language (and most
Python code is also valid Cython code), but Cython additionally supports
calling C functions and declaring C types on variables and class
attributes. This allows the compiler to generate very efficient C code
from Cython code.

This makes Cython the ideal language for writing glue code for external
C libraries, and for fast C modules that speed up the execution of
Python code.

Log message:
Update py-cython to 0.24.

0.24 (2016-03-xx)

Features added

* PEP 498: Literal String Formatting (f-strings).
  Original patch by Jelle Zijlstra.

* PEP 515: Underscores as visual separators in number literals.

* Parser was adapted to some minor syntax changes in Py3.6, e.g.

* 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.

0.23.5 (2016-03-26)

* 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.

Log message:
Add a tool.mk in devel/py-cython to be used by packages that need cython as
a tool without suffix. Based on lang/python/tool.mk.

Log message:
Remove duplicate SHA512 digests that crept in.
   2015-11-03 04:29:40 by Alistair G. Crooks | Files touched by this commit (1995)
Log message:
Add SHA512 digests for distfiles for devel category

Issues found with existing distfiles:
No changes made to these distinfo files.

Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden).  All existing
SHA1 digests retained for now as an audit trail.

Log message:
Update to 0.23.4:

0.23.4 (2015-10-10)

Bugs fixed

* Memory leak when calling Python functions in PyPy.

* Compilation problem with MSVC in C99-ish mode.

* Warning about unused values in a helper macro.

0.23.3 (2015-09-29)

Bugs fixed

* 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.

Other changes

* 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.
