PyPy 2.6.0 发布,Python 解释器
腾讯SNG夏日招聘集结号:200个空缺岗位,JAVA、C++、云计算、Android……PyPy 2.6.0 发布,此版本更新 cffi 至版本 1.1,使得流行的 ctypes-alternative 更容易使用,支持新的 vmprof 统计分析工具。
PyPy 2.6.0 现已提供下载:
http://pypy.org/download.html
PyPY 包括 3 个子项目:
[*] Py3k(支持 Python 3.x)
[*] STM(software transactional memory)
[*] NumPy
值得关注的改进
[*] Python 兼容性:
[*] 改进对 TLS 1.1 和 1.2 的支持
[*] Windows 下载现在是一个 pypyw.exe 加一个 pypy.exe
[*] 支持 PYTHONOPTIMIZE 环境变量 (impacting builtin’s __debug__ property)
[*] 解决了之前版本报告的 issues:https://bitbucket.org/pypy/pypy/issues 或者 IRC at #pypy。
[*] 新特性:
[*] Add preliminary support for a new lightweight statistical profiler vmprof, which has been designed to accomodate profiling JITted code
[*] Numpy:
[*] Support for object dtype via a garbage collector hook
[*] Support for .can_cast and .min_scalar_type as well as beginning a refactoring of the internal casting rules
[*] Better support for subtypes, via the __array_interface__, __array_priority__, and __array_wrap__ methods (still a work-in-progress)
[*] Better support for ndarray.flags
[*] 性能提升:
[*] Improved IO performance of zlib and bz2 modules
[*] We continue to improve the JIT’s optimizations. Our benchmark suite is now over 7 times faster than cpython
[*]
Slight improvement in frame>
[*] Internal refactoring and cleanups leading to improved JIT performance
更多改进请看发行说明。

PyPy 是用Python实现的Python解释器。
PyPy是,Python开发者为了更好的Hack Python创建的项目。此外,PyPy比CPython是更加灵活,易于使用和试验,以制定具体的功能在不同情况的实现方法,可以很容易实施。 该项目的目标是,让PyPy比C实现的Python更为容易的适应各个项目和方便裁剪。
