HTML Parser?
by Joe Hillenbrand Feb. 22, 2013

Feb. 22, 2013

What is the recommended HTML parser to run in PyPy? The typical goto for Python is lxml, but of course that doesn't work with PyPy. Has anyone tested any other libraries? Are there any benchmarks? Thanks, -Joe

pypy and PYTHONPATH
by Davide Del Vento Feb. 21, 2013

Feb. 21, 2013

Folks, I've just installed pypy on a production machine which makes use of PYTHONPATH to let the user pick and chose python libraries installed in non-standard directories. I am wondering if I should wrap pypy with a shell script forcing the -E setting, to prevent picking libraries that it should not (such as numpy and scipy). Thanks!

many of the jit.backend.x86.test are failing, I am willing to put time into solving this but have a bit of no idea where to start.

【Pypy Questions】
by jiaxinrun Feb. 19, 2013

Feb. 19, 2013

Hi,all： I am a fresh man in pypy world! I have a question when I am using pypy for developing. When I import win32process.pyd(something in sit-packets\win32) with pypy.exe , it prompts "ImportError: No module named win32process". I am sure it's not a path problem. But when I import the same thing with python.exe，it works well. So, Can you give me some help? Thanks very much!! Additionally, I have finished a set of program. Now I want to use pypy to fast it. How could I do? Best Regards

Release date for PyPy 2.0 beta 2?
by Dinu Gherman Feb. 17, 2013

Feb. 17, 2013

Hi, I'm trying to make some performance comparisons using various tools like CPython, Cython, PyPy and Numba as described in an exercise I've put up here for a presentation (a tiny function generating digits of Pi): https://gist.github.com/deeplook/4947835 For this code PyPy 1.9 shows around 50 % of the performance of CPython. Christian Tismer tells me 2.0 beta 1 was much better, but I'm running into a bug for PyPy 2.0 beta 1 already described here two months ago: https://bugs.pypy.org/… [View More]

test_all.py can't recognize has multi inherited classes
by James Lan Feb. 15, 2013

Feb. 15, 2013

Hi All, I tried to run test cases for jvm backend by the following command, pypy pypy/test_all.py rpython/translator/jvm/test but what I got was 10 tests defined in rpython/translator/jvm/test/test_backendopt.py although there are two dozens of test files in that directory. After experiment, I found that it failed to collect test within a multi inherited class. Take test_constant.py as an example, it defines a class, class TestConstant(BaseTestConstant, JvmTest): pass … [View More]
