New submission from Jeremy Kloth <jeremy.kloth+python-trac...@gmail.com>:
The string building and comparing of ast.dump() causes significant slowdowns on the large ASTs produced when doing the roundtrip test on the stdlib. This PR avoids that cost by doing a direct node traversal and comparison. It results in a 33% runtime improvement on machines to which I have access. ---------- components: Tests messages: 416082 nosy: jkloth priority: normal severity: normal status: open title: Speedup test_unparse versions: Python 3.10, Python 3.11, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue47131> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
