question on rpython stack reconstruction feature
by alan yung 31 May '09

31 May '09

I tried to use rstack's functions to reconstruct interpreter level stack like following.. http://sourceforge.net/tracker/?func=browse&group_id=58965&atid=489447&stat… I've implemented them as interpreter level functions. In freeze(), I captured python level frame objects, and try to unwind the stack with stack_unwind, and in resume() I try to reconstruct the c frame stack with resume_state_create/invoke and python frame with cloned frames. But it seems like it doesn't take effect at all (I tested it under stackless enabled translated version of pypy) What am I doing wrong? Thanks.

Europython Sprint Announcement
by Carl Friedrich Bolz 29 May '09

29 May '09

================================================================== Birmingham (UK) EuroPython PyPy Sprints 28-29 June/ 3-4 July 2009 ================================================================== The PyPy team is sprinting at EuroPython again. This year there are `sprint days`_ before (28-29 June) and after (3-4 July) the conference. Some PyPy core people should be present during both periods. .. _`sprint days`: http://wiki.europython.eu/Sprints If you plan to attend the sprints after the conference we recommend you to listen to the PyPy technical talk (`EuroPython schedule`_) during the conference since it will give you a good overview of the status of development. Goals and topics of the sprint ------------------------------ There are many possible and interesting sprint topics to work on - here we list some possible task areas: - trying out software on PyPy's Python interpreter: the CPython test suite is not all that complete, therefore the fact that we pass most tests is no real indication of bug-freeness. We have tried and know that frameworks like Django and Twisted work with PyPy. Therefore we would like to try running more "real applications" on top of the Python interpreter (ideally ones that have a good test suite themselves and that don't need unusual extension modules). Running things on Windows is also interesting, we know our coverage there is not as good as on Linux. - check and improve Mac OS X support - starting to work on porting 2.6 features to PyPy's Python interpreter - ongoing JIT generator work - of course we are open to other ideas for what to work on. Examples could be working on other language interpreters, sandboxing, ... ------------ Registration ------------ If you'd like to come, please subscribe to the `pypy-sprint mailing list`_ and drop a note about your interests and post any questions. More organisational information will be sent to that list. Please register by adding yourself on the following list (via svn): http://codespeak.net/svn/pypy/extradoc/sprintinfo/ep2009/people.txt or on the pypy-sprint mailing list if you do not yet have check-in rights: http://codespeak.net/mailman/listinfo/pypy-sprint --------------------------------------- Preparation (if you feel it is needed): --------------------------------------- - read the `getting-started`_ pages on http://codespeak.net/pypy, especially also the `development of PyPy itself part`_ . - for inspiration, overview and technical status you are welcome to read `the technical reports available and other relevant documentation`_ - please direct any technical and/or development oriented questions to pypy-dev at codespeak.net and any sprint organizing/logistical questions to pypy-sprint at codespeak.net - if you need information about the conference, potential hotels, directions etc we recommend to look at http://www.europython.eu. We are looking forward to meet you at the EuroPython PyPy sprints! The PyPy team ..

Let's help the EP organizers with sprint planning
by Samuele Pedroni 22 May '09

22 May '09

Hi, it would be nice if at least people with commit access and who plan to be at the EP sprints this year would put in their dates in the usual planning file by next week: extradoc/sprintinfo/ep2009/people.txt Also we should really think of finalizing the announcement next week with some topics. Thanks, Samuele

PyPy Sprint
by Laura Creighton 22 May '09

22 May '09

Can people edit http://wiki.europython.eu/Sprints or make something on codespeak and then link to it there. Not enough people are signed up for sprinting, and John wonders if it is worth it to rent the rooms -- he is considering cancelling. Laura

How to store RPython object in external c?
by LvQi 20 May '09

20 May '09

Hi all, I'm learning how to use rffi and lltype system to access external C library in RPython. And in some case, I need to store RPython object in external C array. For example: class RPythonObj: def test(): return 1 .... .... c_source=py.code.Source(" void*store=NULL; void c_call_set(???){ store=???; } ??? c_call_get(){ return store; }") _c_call_set=llexternal("c_call_set", [???], lltype.Void, ...) _c_call_get=llexternal("c_call_get", [], ???, ...) def test(): o=RPythonObj() _c_call_set(o) o2=_c_call_get() o2.test() Is that possible? If so, what should I put in ??? Thanks very much~ -- Lv Qi Ph.D Candidate CS Department Nanjing University Nanjing 210093 China Tel: 86-138-5228-2381

EP sprints
by Antonio Cuni 14 May '09

14 May '09

Hi all, the early bid deadline for europython is on may 14th: together with the fee you can also reserve the hotel room, but for doing that we need to know when we plan to do the sprint. IIRC, the idea was to do it before the conference, and maybe also after. Am I right? In this case, until when? I also see on the website that the hotel rooms are for three people: who is interested in sharing? ciao, Anto

removing stablecompiler
by Benjamin Peterson 10 May '09

10 May '09

A while ago, fijal and I were discussing how annoying it is to have to update stablecompiler every time one touches the AST of PyPy's compiler. He suggested that it had served its purpose and can now be deleted. That makes sense to me. Opinions? -- Regards, Benjamin
