Sebastian Berg <sebast...@sipsolutions.net> added the comment: Just to note, that there are two – somewhat distinct – issues here in my opinion:
1. `FromSpec` does not scan `bases` for the correct metaclass, which it could; this could even be considered a bug? 2. You cannot pass in a desired metaclass, which may require a new API function. My patch tries to address the first (the class creator has to take care that this is reasonable for the metaclass). I had hoped the `slot` mechanism can avoid the API discussion for the second one, but I guess not. On the discussion on `tp_type/meta` being incorrect usage: I am slightly surprised we actually care about static C-definitions? There is no reason that a `spec` should be declared static (aside that you have to move it into the function otherwise)? Everything is copied by `_FromSpec` after all. However, I suppose that would replace a safe-by-design API with a "best practice" to never define the spec/slots statically (a best practice that is probably not generally followed or even advertised currently, I guess). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue15870> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
