* bpo-36779: time.tzname returns empty string on Windows if default cod… ↵Miss Islington (bot)2019-06-131-0/+14
| | | | | | | | | | | | | | | | | (GH-13073) Calling setlocale(LC_CTYPE, "") on a system where GetACP() returns CP_UTF8 results in empty strings in _tzname[]. This causes time.tzname to be an empty string. I have reported the bug to the UCRT team and will follow up, but it will take some time get a fix into production. In the meantime one possible workaround is to temporarily change the locale by calling setlocale(LC_CTYPE, "C") before calling _tzset and restore the current locale after if the GetACP() == CP_UTF8 or CP_UTF7 @zooba https://bugs.python.org/issue36779 (cherry picked from commit b4c7defe58695a6670a8fdeaef67a638bbb47e42) Co-authored-by: Paul Monson <paulmon@users.noreply.github.com>

* bpo-36256: Fix bug in parsermodule when parsing if statements (GH-12488)Miss Islington (bot)2019-03-211-5/+17
| | | | | | | | | bpo-36256: Fix bug in parsermodule when parsing if statements In the parser module, when validating nodes before starting the parsing with to create a ST in "parser_newstobject" there is a problem that appears when two arcs in the same DFA state has transitions with labels with the same type. For example, the DFA for if_stmt has a state with two labels with the same type: "elif" and "else" (type NAME). The algorithm tries one by one the arcs until the label that starts the arc transition has a label with the same type of the current child label we are trying to accept. In this case, the arc for "elif" comes before the arc for "else"and passes this test (because the current child label is "else" and has the same type as "elif"). This lead to expecting a namedexpr_test (305) instead of a colon (11). The solution is to compare also the string representation (in case there is one) of the labels to see if the transition that we have is the correct one.
