Can someone review my RPython code?
by Timothy Baldridge May 27, 2012

May 27, 2012

So here's the current status of my Polymorphic functions in as a pypy module: https://bitbucket.org/halgari/pypy/src/d9e7191d13df/pypy/module/clojure/fun… I have a question about the way "space" is handled. My problem is this, I'd like to create several instances of PolymorphicFn on the interpreter level, so I can register some types with the function when the module is loaded. However, I'm not sure how I should do this. If I don't implement __new__ pypy complains that "using object.__new__ … [View More]

checkpointing pypy sandbox in dmtcp
by Naveen Garg May 27, 2012

May 27, 2012

I couldn't figure out what antonio cuni was trying to do with the dmtcp python api here: https://bitbucket.org/antocuni/misc/src/73621b70935f/hack/checkpointing/dmt… anyways, Running the pypy interpreter in dmtcp seems to work out of the box. This works even with the sandboxed interpreter. I did: 1. translate the sandbox using instructions here: http://doc.pypy.org/en/latest/sandbox.html 2. mv pypy-c ~/bin/pypy/bin/pypy-c-sandbox bash1> dmtcp_coordinator bash2> dmtcp_checkpoint python … [View More]

Differences between app and interp level calling methods
by Timothy Baldridge May 27, 2012

May 27, 2012

For my clojure module, I'm trying to figure out if I should go with app level or interp level code. Many of my classes will do dispatching on __call__ or the equivalent. Are interpreter level variadic functions going to be faster (via call_args) vs an app level __call__(self, args_w) ? A bit more background here, Clojure functions dispatch on the number of arguments: (defn + [x] x [x y] (add x y)) [x y & rest] (reduce + (add x y) rest)) For something like this, am I going to … [View More]

buildmaster moved
by Armin Rigo May 25, 2012

May 25, 2012

Hi all, Wyvern, which was the machine serving a few PyPy-related services --- most notably the buildmaster and the nightly builds at buildbot.pypy.org --- more or less died a few days ago. It was after a long life: we had the server around 2005, and now the particular small piece that broke down is no longer found. For information the hard drive was broken once already and is not as old as the rest. So David and remotely Antonio moved the HD inside another machine and reconfigured the DNS. … [View More]

Jit hints from python
by Timothy Baldridge May 25, 2012

May 25, 2012

While looking at ways to optimize the Clojure-Py code (http://github.com/halgari/clojure-py) for pypy, I'm noticing that much of Clojure-Py could benefit greatly from giving purefunction hints to the JIT. For example, let's look at the polymorphic Clojure functions known as "protocols": def ProtocolFn(object): def __init__(self): self.d = {} def extend(self, tp, fn): self.d[tp] = fn def getFn(self, tp): return self.d[tp] def __call__(self, *args, **… [View More]

Translating just the parser for JVM [was: Faster PyPy translation (for debugging)]
