Python 3 preparation: update string translate method call in cgi/accept_language.py. The str translate method in Python 3 is sufficiently different from that in Python 2 that different arguments are needed here. Note that the existing code "ascii = ''.join([chr(x) for x in range(256)])" is redundant with both versions (in Python 2, None can be used instead as the first translate argument from Python 2.6 onwards).

def init_severity(db, cl, nodeid, newvalues):
    """Make sure severity is set on new issues"""
    if 'severity' in newvalues and newvalues['severity']:
        return

    normal = db.severity.lookup('normal')
    newvalues['severity'] = normal

def init(db):
    db.issue.audit('create', init_severity)
