Merge lp:~rackspace-titan/nova/versions_detailed_json_xml into lp:~hudson-openstack/nova/trunk

[William Wolf]

Add support for 300 Multiple Choice responses when no version identifier is used in the URI (or no version header is present)

Also adds support for server detail json/xml/atom requests.

[Brian Waldon (bcwaldon)]

Can you keep all of the XMLNS constant strings in nova.api.openstack.wsgi?

review: Needs Information

[William Wolf (throughnothing)]

Thanks Brian, I hadn't realized some of these were already in wsgi. I'll fix that up.

[lp:~rackspace-titan/nova/versions_detailed_json_xml]

1328. By William Wolf on 2011-07-28

use wsgi XMLNS/ATOM vars

1329. By William Wolf on 2011-07-28

refactoring and make self links correct (not hard coded)

[William Wolf (throughnothing)]

Alright, I think I got the wsgi xmlns variables in use, and fixed up the self link issues.

[Brian Waldon (bcwaldon)]

Looking good, but you've got one pep8 error.

46, 52, 79, 85: (Minor style nit) If you are going to break up strings like this, can you line them up vertically like this:

51 + "href": "http://docs.rackspacecloud.com/"
52 + "servers/api/v1.0/application.wadl"

103-107: Why did you need to add this method? It already has this method from wsgi.Resource's parent class. I did notice the cls() call is different, can you explain?

462,463: Just a note, the trailing comma is preferred to prevent having to add it when a new item is appended to the list.

[William Wolf (throughnothing)]

I think you are right about factory() Brian, we don't need it. I didn't realise that wsgi.Application had it already.

I've fixed the pep8 and other issues as well.

[lp:~rackspace-titan/nova/versions_detailed_json_xml]

1330. By William Wolf on 2011-07-29

fixed pep8 issues and removed unnecessary factory function

1331. By William Wolf on 2011-07-29

merge with trunk

1332. By William Wolf on 2011-07-29

fixed typo

1333. By William Wolf on 2011-07-29

fix more spacing issues, and removed self link from versions template data

1334. By William Wolf on 2011-07-29

fix run_tests.sh

[Brian Waldon (bcwaldon)]

Leave Gabe to me.
