Windows 7 x64 development
by Robert Grosse Sept. 10, 2013

Sept. 10, 2013

Hi, I am interested in working on Windows 7 64bit support for PyPy. Does anyone know what the best way to get started with this is? Is there a list of work that needs to be done to support Windows anywhere?

Specifying lib locations?
by Skip Montanaro Sept. 9, 2013

Sept. 9, 2013

Trying to build from source, I get the complaint, "failed to guess where ncurses is installed." On our systems they are in decidedly nonstandard locations. A bit of googling didn't turn up an obvious solution, and rpython --help didn't spew any lines that looked promising. How do I specify nonstandard locations of the various dependent libraries? Thanks, Skip

Working on a recipe for using travis-ci with pypy projects
by Sarah Mount Sept. 9, 2013

Sept. 9, 2013

Hi there, I haven't had much time to work on rcsp since the Sprint, but I've been tinkering with the infrastructure here and there. I have added the project to the travis-ci.org continuous integration platform here: https://travis-ci.org/snim2/rcsp/ The thing I'm interested in is that it would be nice to use travis to a) run automated tests, b) bulid documentation and c) use rpython to translate to an executable, at the very least to check that the translation doesn't error. This would be … [View More]

What stops ARMed PyPy 2.1 from working on Android?
by anatoly techtonik Sept. 9, 2013

Sept. 9, 2013

I am certain there is no roadmap for Android or else I'd already found it, but still is there any list of issues to be addressed to get PyPy running there? http://morepypy.blogspot.com/2013/08/pypy-21-considered-armful.html Modern Android tablets are ARMv7, so after 2.1 hardware is not an issue. As for platform, it looks like android-scripting project is able to compile CPython to be run on tablet, http://code.google.com/p/android-scripting/source/browse/#hg%2Fpython-build It would be nice … [View More]

Re: [pypy-dev] [pypy-commit] pypy refactor-translator: Remove fork_before option (unused).
by Antonio Cuni Sept. 9, 2013

Sept. 9, 2013

Hi Manuel, did you actually kill support for this feature? I find it occasionally useful: e.g. when working on the JIT you can use --fork-before=pyjitpl and avoid to annotate/rtype the whole pypy interp when you change something. ciao, Anto On 04/09/13 12:13, Manuel Jacob wrote: > Author: Manuel Jacob > Branch: refactor-translator > Changeset: r66781:57dd91f9ccd9 > Date: 2013-09-02 18:08 +0100 > http://bitbucket.org/pypy/pypy/changeset/57dd91f9ccd9/ > > Log: Remove … [View More]

freeze in project under pypy
by Max Lavrenov Sept. 8, 2013

Sept. 8, 2013

Hello, I've tried running our application under pypy and found something strange in its behavior. It is a twisted project which accept users http requests, make request to redis, but most of the request time it spends in cpu intensive calculations. Compared average response time , pypy shows ~30% boost which is cool. But plot with longest response time in 10 seconds period looks weird. I've attached this plot. Blue line - pypy. Green line - cpython Y-axis is time in ms Both application … [View More]

PyPy's PyDateTime_Delta definition
by Skip Montanaro Sept. 7, 2013

Sept. 7, 2013

Python 2.7's PyDateTime_Delta structure is defined like this: typedef struct { PyObject_HEAD long hashcode; /* -1 when unknown */ int days; /* -MAX_DELTA_DAYS <= days <= MAX_DELTA_DAYS */ int seconds; /* 0 <= seconds < 24*3600 is invariant */ int microseconds; /* 0 <= microseconds < 1000000 is invariant */ } PyDateTime_Delta; In contrast, PyPy's version leaves out everything except PyObject_HEAD: … [View More]

Free SSL certificate for https://bugs.pypy.org
by anatoly techtonik Sept. 5, 2013

*.python.org uses free SSL certificate from http://www.startssl.com/?app=1 PyPy can use this too to get rid of annoying security exceptions for https://bugs.pypy.org and other parts. -- anatoly t.

Buildbot update
by David Schneider Sept. 5, 2013

Sept. 5, 2013

Hi all, I just upgraded the PyPy buildbot on buildbot.pypy.org to run on version 0.8.8 of buildbot. This update should not create any significant visible changes and mainly simplifies some things in the codebase. Also the update should make it easier to add some features, such as decoupling the translation from the tests, hopefully allowing to reuse binaries for different test runs. As usual with updates there might be some things that do not work as expected or at all. In case you notice … [View More]
