AttributeError: 'socket' object has no attribute '_reuse'

Dec. 19, 2013

Thanks to Piotr I now got gevent installed. But now I get a new error when trying to run my python program. The Webserver (with SSE) runs but when I try to load a site I get the error below. I need to get it running .. pypy is so awesomely faster than cpython. Robert Traceback (most recent call last): File "build/bdist.linux-armv6l/egg/gevent/greenlet.py", line 328, in run result = self._run(*self.args, **self.kwargs) File "build/bdist.linux-armv6l/egg/gevent/pywsgi.py", line 653, … [View More]

gevent
by Robert Voigtländer Dec. 19, 2013

Dec. 19, 2013

Hi, I am relatively new to python and more or less completely new to pypy. So far I have pypy running on my raspberry pi. I don’t use virtualenv. Modules for pypy I simply installed via easy_installer from the pypy bin dir. I now try to get gevent installed. I found this remark: “stackless support - eventlet <http://eventlet.net/> just works and gevent <http://www.gevent.org/> requires pypycore<https://github.com/gevent-on-pypy/pypycore> and pypy-hacks <https://… [View More]

faster rbigint multiplication
by Mario Pernici Dec. 12, 2013

Dec. 12, 2013

Hello, I would like to submit a patch to rbigint.py (50 lines of code in _x_mul_), speeding up multiplication; on my computer (x86_64) it seems to be at least as fast as CPython for numbers with few words, about 2x faster for numbers with more than 20 words. Where should I post it? Mario

Compiling stmgc-c4 fails on 32bit
by Jean-Philippe Caissy Dec. 9, 2013

Dec. 9, 2013

Hi, I'm trying to compile stmgc-c4 on a fresh Ubuntu 12.04 32bit machine (lxc containers if that matters), and it fails. However, a fresh 12.04 64bit installation, it compiles without any problem. Both the jit and no-jit fail (-Ojit and -O2). The stack trace for the jit is really long, and can be found here : https://gist.github.com/jpcaissy/7862899 and the stack trace for the no-jit can be found here : https://gist.github.com/jpcaissy/7862913 Could that be a bug, or am I doing something wrong? Thanks, JP

Pluggable HTM
by Dimitri Vorona Dec. 9, 2013

Dec. 9, 2013

Hi, the original STM proposal spoke of HTM as of a thing of a far future. Now, Haswells are out and provide built-in HTM support in form of TSX. In the near future I expect more and more systems to have it. Are there plan to make PyPy use HTM if it is available on the system? Regards, Dimitri.

Integrating CPython and PyPy, maybe
by Armin Rigo Dec. 3, 2013

Dec. 3, 2013

Hi all, Starting from last night, the nightly builds of PyPy are able to run this kind of code: http://bpaste.net/show/155166/ (You have to adjust the libpython2.x.so path manually.) The idea is to link in the libpython.so, using cffi. Then you can use it much like you would in C. For example, you can import complete CPython packages and call them. This is similar to the earlier experiments done by fijal about calling matplotlib via CPython, except this time done with cffi. The code … [View More]

clarification cffi vs _ffi_ vs _ffi vs libffi vs _rawffi vs rffi
by Dima Tisnek Dec. 3, 2013

Dec. 3, 2013

there seems to be some confusion (could be all mine) between N terms related to FFI: are there both _ffi_ and _ffi, or is one of those a typo? extending page mentions libffi and not cffi, is it out of date, or is there a reason to stay away from cffi, although recommended in general faq page? in my own testing, I noticed that equivalent code cffi code is faster than ctypes, is there an explanation for this? thanks, d. docs in question: http://doc.pypy.org/en/latest/faq.html http://doc.… [View More]
