Better bsddb error control. Please, review.

Why is my PyErr_Warn() not being printed?
The code: (py_api is the CObject, will be NULL if an exception happened)
if (py_api) {
PyDict_SetItemString(d, api, py_api);
Py_DECREF(py_api);
} else { /* Something bad happened */
PyErr_WriteUnraisable(m);
PyErr_Warn(PyExc_RuntimeWarning,
_bsddb/_pybsddb C API will be not available);
PyErr_Clear();
}
Commit r86180.
Now I have to up-port this patch to the upcoming pybssddb 5.1.1.

Florent Xicluna florent.xicl...@gmail.com added the comment: It is probably related to the CObject PendingDeprecationWarning.

Jesús Cea Avión j...@jcea.es added the comment: Importing bsddb crashes. Importing bsddb3 (the updated version I keep independiently of python) DOESN'T crash. bsddb = 4.8.4 bsddb3 = 5.0.0 (currently). Checking the changelog, I see this possible cause: * Capsule support was buggy. The string passed in to PyCapsule_New() must outlive the capsule. (Larry Hastings) It is 3AM in Spain now. Will check when I find some time. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9675 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Florent Xicluna florent.xicl...@gmail.com added the comment: The crash is triggered because PyDict_SetItemString(d, api, py_api) is called with py_api=NULL when PyCObject_FromVoidPtr returns an error. A possible workaround is to create a copy of PyCObject_FromVoidPtr (e.g. _PyCObject_FromVoidPtr) which is free of warnings. This function will be used by the _bsddb module in Python 2.7.

Jesús Cea Avión j...@jcea.es added the comment: The problem is that the -We is converting the CObject use to ERRORs, when this API is perfectly legal in Python 2.7. bsddb 4.8.4 DOES *legally* uses CObjects in Python 2.7. In pybsddb 5.0.0 I migrated to Capsule, since 5.0 doesn't support python 3.0 anymore (python 3.0 didn't support capsule). I can commit a 4.8.4.1 version with Capsule support, for I think this crash is overzealot. According to http://bugs.python.org/issue7992#msg104140 , CObject is not actually deprecated in Python 2.7, so it should not cause CObjects use with -We to be an error. Read the mail thread. In particular: http://mail.python.org/pipermail/python-committers/2010-April/000882.html . I would suggest to drop DeprecationWarnings for CObjects in 2.7.1.
