Is anybody planning to give a talk on PyPy for OSCON?
by Laura Creighton Feb. 13, 2003

Feb. 13, 2003

This is precisely the sort of thing that Nat Tarkington said he wanted for the Python track -- new community efforts, new implementations. Who is going to OSCON here besides me? Laura Creighton

Re: [pypy-dev] Scons?
by Charles Crain Feb. 13, 2003

Feb. 13, 2003

(in response to Holger Krekel's question about SCons) I am on the SCons development team, and can answer any questions you have about using SCons for PyPython. It's still "technically" in Alpha, which by our definition simply means it is not feature complete. However, the features it does have are extremely stable and well-tested...we have a very large automated test suite, a rigorous testing process, and a growing user community. We make releases about once a month (we try to anyway), and … [View More]

reusing existing work: Parrot
by Tobias Oberstein Feb. 12, 2003

Feb. 12, 2003

more by accidence, I came across the following stuff http://www.parrotcode.org which might be of interest when it comes to - reusing existing work in PyPy - focusing PyPy (whatever this means) and concentrating manpower .. Parrot will be the new VM written from scratch for Perl6. The developers claim that its generally suitable for dynamically typed languages - which fits Python as well. Also it is designed as an abstract register machine, which they claim will provide better … [View More]

Updates from the sprint?
by VanL Feb. 12, 2003

Feb. 12, 2003

For those of us who are unable to get to Germany, is there any way to get updates from the sprint? These don't have to be cooked or processed -- we can do that, and the sprinters can sprint. But being able to follow what goes on would be very interesting. If I could get all I would wish for, we could get: 1. Some sort of recording of the talks given each evening. 2. Presentation materials 3. The code snapshot from the previous night. Would this be possible? Van

Scons?
by holger krekel Feb. 12, 2003

Feb. 12, 2003

Hello, i have been following the SCons effort for quite some time without seriously deploying it. I know that Skip Montanero did some tests with the CPython-sources and said he liked it. Is anybody here on the list who knows enough about SCons to tell what the current state of it is? And if it would suite the CPython-build process? Anybody tried anything? If we want to do it i imagine that we could contribute it to CPython if there is interest. Yes, i know there is a bootstrapping … [View More]

multiple isolated VMs in a single process
by Tobias Oberstein Feb. 10, 2003

Feb. 10, 2003

Are there any design plans regarding threading architecture yet? I particular, are you planning to support having multiple interpreters in one process _without_ sharing objects (no free threading but VM-wise locking). Supporting this would require early design decisions like - no global data for the interpreter/VM - no global data in object implementations - but what about extension modules? many have global data .. isn't it? Also, in an C embedding API, will the VM-state be take from … [View More]

Wiki content
by Armin Rigo Feb. 9, 2003

Feb. 9, 2003

Hello everybody, I have put some content into the Wiki. It is some kind of a technical summary of all the aspects we discussed so far -- a very subjective one, anyway. Any different opinion is of course welcome. And if I missed your pet subject, I give you my apologizes (but after you receive them, go ahead and add it to the Wiki :-) http://codespeak.net/moin/pypy/moin.cgi/PyPythonProjects I inserted a couple of links to my own experiments in the Wiki pages: * a Python-interpreter-… [View More]
