Christopher Lee <l...@chem.ucla.edu> added the comment: I suspect that for most users, shelve is the main way they will access the dbm.* interfaces. Based on that, the dict methods that are really needed on dbm.* objects are just: __iter__, __len__, __getitem__, __setitem__, __delitem__, __contains__, has_key, and keys.
Note: Issue 5736 aims to make dbm.* support the iterator protocol, which would be crucial for making shelve iteration scalable (currently, iterating on a Shelf will call self.dict.keys(), loading the entire index into memory!). The dbm.* docs could also explicitly tell users who want a *complete* dict interface to create a class that inherits from both dbm and UserDict.DictMixin / MutableMapping. ---------- nosy: +foobaron _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue6045> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
