Serhiy Storchaka added the comment: Oh, sorry, I did not notice test_yaml_linkage. And in any case this test was broken (should be rv[1][0] instead of rv[1]).
I don't like to revert these changes, and the reversion can break a code written for 3.4 which pickles recursive OrderedDicts. I suggest following solution. PyYAML calls __reduce_ex_(2) or __reduce__(). Therefore we can return to old behavior with protocol < 3 and left current behavior with protocol >= 3. Recursive OrderedDicts will be pickleable with default protocol and with highest protocol, and PyYAML will be happy. Does this patch look good to your? ---------- stage: needs patch -> patch review Added file: http://bugs.python.org/file37106/OrderedDict_pickle_PyYAML.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue17900> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
