Do we *really* need those functions available on RPython level?

Idea for speed.pypy.org
by Jacob Hallén Dec. 4, 2010

Dec. 4, 2010

Something that would be nice on the speed.pypy.org site would be that each benchmark links to a page that describes the benchmark - What the benchmark is designed to measure - Why PyPy performs better/worse than CPYthon (if known) - What might be done to further improve performance (if there are ideas) - Link to the source code of the benchmark Any takers?

Testing if a function exists?
by Dan Stromberg Dec. 4, 2010

Dec. 4, 2010

How does one test if a function exists in pypy? In CPython 2.x and 3.x, it appears to be sufficient to use: 'funcname' in __bultins__ ...but that doesn't appear to work in pypy 1.4: >>>> print 'platform_version' in platform Traceback (most recent call last): File "<console>", line 1, in <module> TypeError: 'module' object is not iterable >>>> print 'bytes' in __builtins__ Traceback (most recent call last): File "<console>", line 1, in <… [View More]

pyopengl on pypy, take 2
by rndblnch Dec. 2, 2010

Dec. 2, 2010

hi, with your help, i have been able to patch pyopengl to make non-trivial glut/opengl interactive programs (involving shaders, vertex and pixel buffers) run on pypy. the programs: http://bitbucket.org/rndblnch/opengl-programmable/ some details about pyopengl modifications here: http://thread.gmane.org/gmane.comp.python.opengl.devel/1004/focus=1007 the only thing i add to change that is not already in the pypy svn is a minor check in _ctypes._Pointer.setcontents to make it raise a … [View More]

hi, i'm trying to make some pyopengl [0] -based code [1] run on top of pypy. this is partially successful, but i need some advice to progress further. pyopengl 3.x makes use of ctypes to provide the opengl binding, and it works out of the box for simple functions (those that do not takes c-pointer to buffers of data as arguments). for the rest, the first issue is that pyopengl use two functions from the ctypes.pythonapi lib, namely PyString_AsString and PyBuffer_FromMemory. any advice on how … [View More]
