Mailman 3 August 2011 - pypy-dev

A basic question.
by Joe Goldthwaite Aug. 16, 2011

Aug. 16, 2011

I apologize if this is the wrong place for this. In looking at the archives this list seems to be more geared to the developers than users. I couldn't find a list for end users though so I'm going to post it here. I'd like to try pypy for a simple project. I'm trying to use SUDS to retrieve data from a web service. SUDS uses a setup.py file to do the install. When I try that under pypy I get a message; ImportError: No module named setuptools I know I need setup tools but how do you … [View More]

Linux 3.0 kernel fallout

It appears that the tests for 'linux2' in Python and PyPy libraries are broken by the appearance of Linux 3.0 kernels. - David

PPC64 JIT progress
by David Edelsohn Aug. 16, 2011

Aug. 16, 2011

Attached is the next patch for the PPC JIT backend. The patch adds shift-left simplified mnemonic (sldi) and a load doubleword (load_dword) function that uses it. I also discovered some typos in my previous patch to ppc_field.py. Currently every PPC JIT testcase fails on PPC64 Linux because the PPC backend makes an incorrect assumption about function pointers. PPC64 Linux function pointer point to function descriptors, not code addresses. PPC64 Linux libffi knows this, which makes def … [View More]

go benchmark
by Hakan Ardo Aug. 16, 2011

Aug. 16, 2011

Hi, I've been looking a bit at the go benchmark, which sometimes is significantly slower on jit-short_from_state. What's happening with default trace_limit=12000 on trunk is that the loop in random_playout is compiled into a loop containing 209 guards and the loop in computer_move is compiled into a loop with 390 guards. After that a lot of bridges are created. So I'm guessing we have some large loops here with a lot of different paths that are common. I patched go.py to print the number of … [View More]

1.6 status report
by Maciej Fijalkowski Aug. 16, 2011

Aug. 16, 2011

Hi A little status update from my side. I'm trying to get 1.6 out of the door and there are a few things that stand out before we can do it. * Windows situation (a lot of crashes with missing liveness). Also lib-python tests take 10h which is a bit too much IMO (not a new regression though) * OS X situation (missing buildbots, being addressed now) * A bunch of issues that either should be decided we don't care or we do care and fix it. * Missing jitviewer release/demo that I'm doing right … [View More]

PyPy, C/C++ and Wrappyr
by Vincent den Boer Aug. 15, 2011

Aug. 15, 2011

Hello evryone, I've just launched a project on GitHub called Wrappyr that may be of interest to the PyPy project. It is a collection of tools that can generate Ctypes-based APIs to C and C++ code. As I understand Ctypes is currently the cleanest way to communicate with C libraries in PyPy, so this may help replacing CPython extensions that are needed for more widespread usage of PyPy. It's available at: https://github.com/ShishKabab/Wrappyr/ It works by: * Using Clang to export data … [View More]

Efficiently piecing together callables with hooks?
by Timo Paulssen Aug. 15, 2011

Aug. 15, 2011

Hello List, I'm currently experimenting with a piece of software I've recently started maintaining, which is a cellular automaton simulation software. It's supposed to make experimenting easy, but still be fast at simulating. As you might know, all cellular automatons operate in steps, where usually the whole "configuration space" is iterated over and all fields are updated depending on their neighbourhood and the "local transition function". Currently, the step functions are implemented in C … [View More]
