planning the 0.6.2 PyPy release
by holger krekel June 10, 2005

June 10, 2005

Hi pypy-devers, at our 2nd June IRC developer meeting (minutes were posted on this list) we decided that we aim for a new micro release 0.6.2 around 23rd June. Yesterday the issue tracker has been reformed to help more with sorting through the various issues we have to resolve in the next time. The current 0.6.2 issues are linked from the issue tracker home page on the left side (you'll get nicer nicer views if you register/login): https://codespeak.net/issue/pypy-dev/ You'll note … [View More]

New genc implementation
by Ben.Young＠risk.sungard.com June 9, 2005

June 9, 2005

Hi All, I was interested in playing with the new c translator, and was wondering if there was a way of using it yet through the general Translator class, or whether it has not been plugged in at this point? Is it possible to use it in translate_pypy, even if it doesn't compile? Cheers, Ben

Re: [pypy-svn] r13221 - in pypy/dist/pypy/rpython: . test

Hi Arigo, Looking at these commits, I just have a quick question. Can the ll_ functions call each other? If they could then all the ll_delitem functions could just delagate to the noneg versions. Also, does the bounds checking happen at this level, or at a lower one. In a week or so I may have a little time to do a bit of coding. Is there anything specific I should look at? For instance I noticed that at the moment the list rep resizes exactly. The python version (and stuff like std::… [View More]vector in c++) have a overallocation stratagy thay minimises allocation calls. Would this be an idea I could try to implement in rpython?

Regular expressions on 2.4
by Armin Rigo June 4, 2005

June 4, 2005

Hi, Regular expressions don't work at all on 2.4, it seems. We hoped at one point that the 're' bytecodes would be kind of compatible, but they seem to be deeply incompatible. I can't get any match, actually. re.compile('a').match('a') returns None. That's worse than the previous situation, where 'import re' would crash in 2.4... Armin

dev meeting 2nd June 3pm (CEST)
by hpk＠trillke.net June 2, 2005

June 2, 2005

Hi pypy-dev, it makes sense to discuss a few issuses regarding future development work (apart from the very nice and successful translation meeting we had last week). I suggest to meet Thursday, 2nd June, 3pm (CEST == GMT+1) on #pypy at irc.freenode.net. Here are suggested topics: - sprint announcement/themes: although times and city are fixed already, the actual sprint topics for the post-europython sprint from 1st July - 7th July in Goetheborg (Sweden) are not yet … [View More]decided and announced. However, almost all active developers will come and it's already safe to reserve the time and book your flights if you want to attend a newcomer-friendly sprint! - release planning: there is the idea to do a PyPy-0.6.2 around EuroPython or even as the finishing event of the public EuroPython sprint. Goals for this possible release need some discussion, though. Here is a suggestion: - move our lib-python base to 2.4.1 - make documentation more complete (e.g. interpreter/ docs are still missing) - integrate parser module (possibly making it RPython conformant) (- maybe offer a small tool to translate small RPython programs) - giving the translation efforts a stable base: One problem with ongoing development of PyPy is that the translation process is still somewhat fragile with respect to type inference (annotation) on our source tree. Therefore, it would be good if translation could for some time rely on a non-changing PyPy base. One simple idea is to fork off translation work in a branch, although i'd like to avoid that if possible. For starters, documentation changes in the branch would not be immediately seen on the website. Any other _simple_ ideas? - Advancing Issue Tracking: we probably want to decide how we proceed with issue tracking and especially classifications of issues. There is the simple idea of assigning an 'easy', 'medium' and 'hard' value to each issue to make it easier for newcomers and for ourselves. Moreover, if we go for a 0.6.2 release i think we should redesign the tracker schema to use 'release' instead of 'milestone'. - news/infos: there are news regarding a guy who is likely to enter the EU/PyPy project and who comes from the Squeak (Smalltalk mostly implemented in Smalltalk) world. Just so you know. - anything else i forgot (please post before instead of suggesting it at the meeting -> better planning) cheers & see you, holger [View Less]

Fw: Expected failure?
by Ben.Young＠risk.sungard.com June 2, 2005

June 2, 2005

Hi there, I follow the pypy development, and tend to sync to head every day or so. I recently noticed some test failures that don't seem to be going away, and was wondering whether there is something wrong with my configuration or if there was something wrong with the way I was running the tests. I addition I noticed that some tests are skipped due to a floating point error. Is this expected too? I run the tests with python 2.4 on cygwin.
