The Prototyping Join Patterns with stackless.py Slides
by Andrew Francis Dec. 22, 2011

Dec. 22, 2011

Hi Folks: I recently gave a rather hastily prepared talk at Montreal Python called "How to Solve a Problem like Santa Claus: Prototyping Join Patterns with stackless.py for Stackless Python." One can get the slides at http://wp.me/pdqoq-46 more information is on my blog. http://andrewfr.wordpress.com once again, I demonstrate how stackless.py can be used to prototype concurrency features for Stackless Python. This time the feature is join patterns. I feel I have come up with a good … [View More]

Mixed pypy and cpython with multiprocessing
by Andrew Brown Dec. 21, 2011

Dec. 21, 2011

Hello everyone, I've been playing around with distributed computing with multiprocessing on CPython, and thought I'd see if I could spin up some workers running pypy and have them connect to a server running CPython. Well, it didn't go so well. The client always gets an IOError: bad message length in the answer_challenge() function of connection.py. Traceback (most recent call last): > File "app_main.py", line 51, in run_toplevel > File "client1.py", line 6, in <module> > … [View More]

very slow ctypes callbacks
by Arman Bostani Dec. 19, 2011

Dec. 19, 2011

Hi all, I believe this problem has been brought to your attention before. But, perhaps it something that can be added to the bug list. I'm using a proprietary Windows library which unfortunately uses callbacks a lot. I've attached a simple test case. Under pypy 1.7, this runs about 8 times slower than CPython 2.7. Best, -arman

New sandbox failure: pypy__float2longlong

ctypes tests
by Armin Rigo Dec. 14, 2011

Dec. 14, 2011

Hi all, I think we could decide by now what to do with the remaining 34 @xfail tests of ctypes. It seems nobody noticed that we don't really implement the full CPython-2.7-compatible ctypes. (As far as I'm concerned, it adds "features" mostly in the form of more and more obscure special cases.) So what do you say about being fine with the current 2.5-compatible situation and silencing the failure on buildbot? http://buildbot.pypy.org/summary/longrepr?testname=unmodified&builder=pypy-…… [View More]

Non standard ASTs
by Timothy Baldridge Dec. 13, 2011

Dec. 13, 2011

For some time now, I've been working on my Clojure/pypy implementation. However, I'm starting to wish I had a few Clojure facilities while writing my rpython clojure interpreter. Basically I would love to have macros, protocols, symbol resolution, and a ton of other little features for helping with run-time code generation and the like. So this is when I started thinking about generating python code from Clojure source. That is, in Python we have a AST, and in Clojure we can parse LISP lists … [View More]
