In fact here is no need for a dummy pointer. When deleting from a split-table, the value can just be set to NULL, the resulting key-NULL pair is legal in a split-table. Your suggestion doesn't make the code any more complex, so I've included it. In practice, it will very rare that a deletion occurs in a split table (since they are only used for attribute dictionaries). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue13903> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
