New submission from Antoine Pitrou <pitrou@free.fr>: In http://docs.python.org/dev/extending/newtypes.html, you can read: “To enable object creation, we have to provide a tp_new implementation. In this case, we can just use the default implementation provided by the API function PyType_GenericNew(). We’d like to just assign this to the tp_new slot, but we can’t, for portability sake, On some platforms or compilers, we can’t statically initialize a structure member with a function defined in another C module, so, instead, we’ll assign the tp_new slot in the module initialization function just before calling PyType_Ready()” But the thing is, we ourselves (CPython) do exactly what is discouraged here, both in built-in types and dynamically loaded extensions. So is this piece of advice still necessary? ---------- assignee: docs@python components: Documentation messages: 117984 nosy: docs@python, loewis, pitrou priority: normal severity: normal status: open title: Outdated advice in C-API tutorial? type: resource usage versions: Python 2.7, Python 3.1, Python 3.2 _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue10024> _______________________________________
