So it turns out this is the default behavior by argparse. Specifying an option more than once with the default action='store' just stores the last occurrence, see:
http://stackoverflow.com/questions/12461087/detecting-if-any-command- line-options-were-specified-more-than-once-with-optpars If we wanted a list, we'd use action='append' but that's not what we want. I think the default of action='store' to allow multiples but ignore all but the last seems weird, but maybe argparse has never fixed that since it'd break a default behavior, and thus probably a lot of scripts. If you wanted to enforce this in novaclient, it sounds like you have to write your own Action class which enforces that only one option is specified. ** Changed in: nova Status: New => Invalid ** Changed in: python-novaclient Status: New => Invalid -- You received this bug notification because you are a member of Yahoo!
