I don't know this area of Nova code at all, but I must say I'm surprised that it actually needs explicit extra work to accept or output XML, instead of JSON. It should be possible to auto generate an XML document from a JSON document, and vica-verca. At which point you'd not need to have 2 sets of tests for JSON vs XML, all you need test is the XML<->JSON conversions. I can imagine this isn't done because of a need to maintain compat with some special XML schema that isn't a direct 1-1 mapping from the JSON schema ?

If we can get to a position where we auto-generate XML from JSON for Nova, we could do the same for other projects too Regards, Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :| _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
