PyPy-Performance versus various other VMs
by Dimitri Vorona April 8, 2013

April 8, 2013

Hi everyone, just wanted to bring to your attention this blog post: http://attractivechaos.wordpress.com/2013/04/06/performance-of-rust-and-dar… . PyPy ist compared with various dynamic and static languages. While the perfomance is still OK (within an order of magnitude of C), it places last by a quite big margin. I would like to know if these result match your benchmarks or is the implementation of the sudoku solver non-optimal for pypy (can be seen here https://github.com/attractivechaos/… [View More]

2.x -> 2 lib rename
by Maciej Fijalkowski April 3, 2013

April 3, 2013

hello everyone I'm incredibly unhappy about the 2.7 -> 2 lib rename. It broke virtualenv, there is no recent virtualenv available and there is absolutely no good reason why we did that. I'm now spending tons of time trying to think how to update virtualenv to a TOT version a bit everywhere. I'm inclined to do a simple revert (or re-rename it) Cheers, fijal

prevent extension module code from being executed during startup?
by wlavrijsen＠lbl.gov April 1, 2013

April 1, 2013

Hi, when starting pypy-c, I get some extension module code executed before that module is imported. The code in question is in pypy/module/cppyy/pythonify.py: gbl = make_cppnamespace(None, "::", None, False) # global C++ namespace gbl.__doc__ = "Global C++ namespace." sys.modules['cppyy.gbl'] = gbl This code is not rpython code. The module is first mentioned in the __init__.py of cppyy: appleveldefs = { 'gbl' : 'pythonify.gbl', '… [View More]
