I can see three kinds of reasons: - Reference count mistakes, that normally don't show up in CPython (but many c extensions do crash when you delete them from sys.modules, then reimport them; cpyext just detect the failure the first time :-) - unsupported functions, either because we never encountered them, or because they are really hard to support in pypy - extensions that play too much with CPython inter nals: numpy, Cython are in this case > can anyone weigh in on dict/custom data structure lookup, e.g. splay > tree vs pointer-chasing linked shadow objects? > is there a better data structure than a has table (void* -> ssize_t) Probably! The hash table is used because it's readily available in RPython. But if you care to provide a RPython implementation of the associative container, I'd be happy to test it. -- Amaury Forgeot d'Arc _______________________________________________ pypy-dev@codespeak.net http://codespeak.net/mailman/listinfo/pypy-dev
