New submission from Joe Amenta <ament...@msu.edu>: In Lib/lib2to3/pytree.py, Node.pre_order() calls the post_order() method of its children, instead of pre_order(). As a result, the only difference between the two orderings is that pre_order() yields the original node first, whereas post_order() yields the original node last. It seems highly unlikely to me that any code would depend on this behavior.
The fix, of course, is trivial: change the call to child.post_order() on line 289 into a call to child.pre_order(). ---------- components: 2to3 (2.x to 3.0 conversion tool) messages: 113233 nosy: joe.amenta priority: normal severity: normal status: open title: node.pre_order() does not do preorder traversal type: behavior versions: Python 2.6, Python 2.7, Python 3.1, Python 3.2 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue9541> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
