Merge lp:~dobey/ubuntu-sso-client/new-kr-props into lp:ubuntu-sso-client

[dobey]

Use the new property names for fdo secrets API

This seems to work on both versions of gnome-keyring (2.3x in 11.04, and 3.x in 11.10).

[Natalia Bidart (nataliabidart)]

The code looks good, but when running this branch and having the control panel using it, I got the error below when trying to remove the current device:

2011-06-21 19:52:26,337:337.815999985 - ubuntu_sso.main - ERROR - CredentialsManagement: emitting CredentialsError with app_name "Ubuntu One" and error_dict {'errtype': 'DBusException', 'message': dbus.String(u'Invalid properties')}.

Same error when trying to store credentials in the keyring:

2011-06-21 19:56:07,373:373.473882675 - ubuntu_sso.main - DEBUG - SSOLogin: emitting LoginError with app_name "Ubuntu One" and error {'errtype': 'DBusException', 'message': dbus.String(u'Invalid properties')}

This test was made on a Natty (updated today) machine.

review: Needs Fixing

Use fallbacks everywhere we use properties, and update the tests accordingly

[Natalia Bidart (nataliabidart)]

It works very good now!

The code looks very good. Some comments:

 * Please change CLXN to COLLECTION for consistency, even if the constants are not exported.
 * why did you change the out_signature of SecretServiceMock.CreateCollection? I'm looking here, and it's still a "o", but perhaps it's changed on gnome-keyring 3: http://code.confuego.org/secrets-xdg-specs/re01.html
