Some NumPyPy propositions
by Dmitrey Jan. 18, 2012

Jan. 18, 2012

hi all, I would like to make some propositions wrt NumPy port development: 1) It would be nice to have a build and/or install parameter to available usage of numpypy as numpy, e.g. "setup.py build --numpypy_as_numpy". I know it can be done via some tricks, but explicit parameter would be better, especially for unexperienced users. 2) Many soft packages have some basic functionality without full numpy port, but due to importing issues they cannot yield even it. For example: from numpy … [View More]

Work on the JVM backend
by Michał Bendowski Jan. 17, 2012

Jan. 17, 2012

Hello everyone, Back in the summer I asked on this mailing list if there's interest in moving the JVM backend forward. Back then there was some enthusiasm, so I got back to it when I had the chance, which unfortunately was a few months later. The suggestion back then was to look into using JPype to integrate more closely with Java-side code, and that's what I would like to do. But before that, I noticed that the JVM backend fails to translate the standard interpreter and spent some time … [View More]

GIL hacks in pypy
by Timothy Baldridge Jan. 14, 2012

Jan. 14, 2012

I'm in the process of writing some semi-multithreaded code in PyPy. Now I know that PyPy and CPython both have GILs, but what I need is a CompareAndSwap operation in Python code. So basically I want my python code to grab the GIL, execute a small block of code, then hand the GIL back. Python doesn't really give a way to do this. But in CPython we can do this ugly little hack for getting "free" locks where you basically set the GIL "remaining" bytecodes count to 32 billion, execute your code, … [View More]

pypy 64 bit Ubuntu packages
by kgardenia42 Jan. 13, 2012

Jan. 13, 2012

Hi, (Not sure if this is the correct place to ask this but I thought someone on this list would be able to help). I have an Ubuntu package which I would like to state a dependency on pypy. I found this excellent PPA resource for pypy Ubuntu packages: https://launchpad.net/~pypy/+archive/ppa http://ppa.launchpad.net/pypy/ppa/ubuntu/pool/main/p/pypy/ However, even though these packages have a target architecture of "all" when I install them on an amd64 Ubuntu machine I am unable to run … [View More]

Re: [pypy-dev] [pypy-commit] pypy default: TEMPORARY: put a limit (4 by default) on the number of "cancelled,

Yes, this breaks Pyrolog. That's fine, I can probably just increase the number. Could you write a test for this commit, though?

Use pypy if available otherwise fallback to CPython
by kgardenia42 Jan. 10, 2012

Jan. 10, 2012

Hi, I have some python code (lets call it main.py) which I'd like to run with pypy if available/installed but otherwise fallback to CPython. Clearly if I call my main.py explicitly with either "pypy" or "python" as follows then I will get the behavior I want: python main.py pypy main.py However, my goal is that main.py is executable and I can just do: ./main.py and it will use pypy if installed, otherwise fallback to normal python. In the archives of this list I found the … [View More]
