improved cpyext PyArg_ParseTuple s* and t# support
by exarkun＠twistedmatrix.com April 23, 2011

April 23, 2011

Hello, There's a pyarg-parsebuffer-new branch in the pypy bitbucket repository that improves PyArg_ParseTuple. It doesn't completely implement either of these, but it adds enough for pyOpenSSL to mostly work. Arbitrary new-style buffer support was too hard for me, so I skipped that. Still, it would be nice to have this branch in 1.5 if possible, since I think with it along with my pyOpenSSL branch, pyOpenSSL becomes mostly functional on PyPy. Can someone take a look and let me know … [View More]

rlib parsing
by Ian Overgard April 21, 2011

April 21, 2011

Hey guys, I was playing around with using the parser generator in rlib, but I'm having some trouble figuring out how to get it to work in rpython (I did get one working in normal python though). Is there a resource on using it somewhere, or maybe just a few pointers? (I realize it's probably in a pretty beta state, but so far it seems like the only parser-generator that's runnable in rpython without really big changes). I was reading this: http://codespeak.net/pypy/dist/pypy/doc/rlib.html#full-… [View More]

Problem with large allocation in test
by Joe April 21, 2011

April 21, 2011

I was trying to run the test file: pypy/jit/backend/x86/test/test_rx86_64_auto_encoding.py and was getting the following traceback: http://paste.pocoo.org/show/374129/ If you look at the comment on line 17, it's trying to allocate much more memory than I have. I think it's a total of 21GB, while I only have 4GB. I'm using 64bit OpenSuSE 11.4 for my operating system. I had the kernel setting overcommit_memory set to 0 (which may be part of the problem). Anyway, after I went into ll2ctypes.… [View More]

Sorry I forgot to reply to the list. The first step would be to tell us the error you are getting. But the fastest way to solve your problems, and get help learning how to debug pypy is to join the pypy channel at freenode (IRC) On Tue, Apr 19, 2011 at 8:54 PM, Ian Overgard <ian.overgard(a)gmail.com> wrote: > That's what I thought too (my code is exactly like that), but something in > it is causing the translator to break, and the error I get back doesn't seem > to tell me … [View More]

Possible sprint in Genova before/after Europython
by Antonio Cuni April 18, 2011

April 18, 2011

Hi all, as we were discussing yesterday in another thread, the post-europython sprint will be only two days long, and so we might want to have a longer one either before or after europython. I am considering organizing one in my place. It could be either in Genova or more preferably in some other town in the nearby of the italian riviera. The place is ~3hr away from Florence by train. Googling images for "pegli" or "arenzano" (i.e., two of the towns we could go to) shows pictures which (I … [View More]

project infrastructure issues
by holger krekel April 18, 2011

April 18, 2011

Hey all, now that pypy's codespeak subversion usage is basically gone i'd like to push for remaining issues related to the pypy infrastructure: - apache/website - buildbot/master - roundup/issue tracker - mailman/mailing lists pypy-dev/commits/z Which of them shall we try to move elsewhere? My preliminary suggestion: - website -> readthedocs? or other site - buildbot -> python.org? or other site - issue tracker -> bitbucket issue tracker - mailing lists -> google groups or … [View More]

Hi Hakan, thanks for the commits > + # We want to check that the array bound checks are removed, > + # so it's this part of the trace. However we dont care about > + # the force_token()'s. Can they be ignored? yes, I think they can be just ignored, because AFAIK operations without side effects and whose result is unused, are removed by the backend regalloc. ciao, Anto

The JVM backend and Jython
by fwierzbicki＠gmail.com April 14, 2011

April 14, 2011

Hi all, It was nice meeting up with many of you at PyCon! I've been thinking about the first steps towards collaboration between the Jython project and the PyPy project. It looks like it isn't going to be too long before we are all (CPython, PyPy, IronPython, Jython, etc) working on a single shared repository for all of our standard library .py code. In my ideal world there would come a day when there is also no standalone Java code in the Jython project: that is the shared standard library … [View More]
