Julien Palard added the comment: Problems looks from `Modules/_sqlite/statement.c`:
``` if (!_need_adapt(current_param)) { adapted = current_param; } else { adapted = pysqlite_microprotocols_adapt(current_param, (PyObject*)&pysqlite_PrepareProtocolType, NULL); if (adapted) { Py_DECREF(current_param); } else { PyErr_Clear(); adapted = current_param; } } ``` It has not changed since 2006, since e200ab5b3e (backport from pysqlite2 SVN repository). I read it as "If an parameter needs an adapter, and the adapter fails, that's OK, continue with the original (unadapted) parameter.", which looks wrong to me, but I may miss something obvious? I tried to set an error instead of restoring the `current_param` and the 261 tests went well, but I'm not yet aware of the coverage of adapters in tests. ---------- nosy: +mdk _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28729> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
