Adam Williamson added the comment: Aha, so thanks to my colleague Patrick Uiterwijk, we see the problem. Since Python 3.3, Python doesn't actually use that pure-Python iterparse() function if it can instead replace it with a C version:
https://github.com/python/cpython/blob/3.3/Lib/xml/etree/ElementTree.py#L1705 "# Overwrite 'ElementTree.parse' and 'iterparse' to use the C XMLParser" so the reason defusedxml wants to use _IterParseIterator on Python 3 is because if it just uses xml.etree.ElementTree.iterparse() it's getting the 'accelerated' C implementation, not the pure-Python implementation it wants. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29050> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
