Re: [pypy-dev] [pypy-commit] pypy default: Move the loop in contains() into a seperate function, so it can be inlined if it doesn't hit the fallback case.

We should do such stuff automatically - it's getting annoying.

My experience is that if you have a clear goal and start by writing a failing test, then it's easier to follow what's going on in that particular case.

Stackless work
by Da_Blitz May 21, 2011

May 21, 2011

Hi keeping this one short and simple I am interested in using JIT enabled stackless with pypy (obviously a feature that doesn't exist). i have been playing with the coroutines interface (which i am finding nicer to work with than tasklets) but don't have the skill to pull of the stackless work it has been suggested that pypy devs are willing to work on paid for features. so if anyone is interested in doing work on stackless and being paid for it please feel free to get in touch of me so … [View More]

PyPy compile memory requirements
by David Naylor May 20, 2011

May 20, 2011

Hi, I'm sure you all know that translating pypy requires a large amount of RAM. It has been my experience that GCC also uses a large amount of RAM when compiling, about 4G. Is it possible to get python/pypy to stop once it has written the source files and then to run that build process separately, thus avoiding having both pypy and gcc in memory at the same time? This is on FreeBSD/amd64: # gcc -v Using built-in specs. Target: amd64-undermydesk-freebsd Configured with: FreeBSD/amd64 system … [View More]

PyPy platforms/architectures
by David Naylor May 18, 2011

May 18, 2011

Hi, I am busy writing a port for pypy on FreeBSD. I have the basics done but I have a slight issue with the package list. It appears pypy creates some files based on the architecture name [1] however the names it uses for those files differ to what FreeBSD uses [2]. I've mapped the obvious name difference (i386->x86_32, amd64->x86_64) however I am not sure what pypy uses for the other architects. Also it appears FreeBSD uses "powerpc" for ppc (even though [2] says otherwise). Please … [View More]

Hi all, the pypy issue tracker has moved from the good old codespeak host to a new one. If you go to one of the old URLs you should be transparently redirected to https://bugs.pypy.org You should be able to use your original login, however please note: - if you used your codespeak credentials and don'T know your actual roundup password you may need to trigger a password reset via "Lost your Login?" - you'll get an SSL warning because we use a self-signed certificate (the IP is … [View More]

sqlite warnings

May 16, 2011

I ran a script I had that used SQLite with storm, and saw a bunch of RuntimeWarnings about args and return times. I took some time to fix them up, and ran the sqlite tests to fix any remaining ones. Joe
