Comment 9 for bug 967064

Ok, so I have verified verbally with David (and per his comment #8 above) that we are to go with requiring sign-in along with recommendations opt-in. In fixing bug 973612, I have implemented most of what we need for this bug as well.

  lp:~gary-lasker/software-center/recommendations-sso-login-lp973612

The above branch implements the SSO sign-in specifically for recommendations, and it reuses the already-existing opt-in text from the lobby panel in the SSO dialog itself so that we can avoid adding a whole new string so far after string freeze. This seems a perfectly reasonable approach to me, and I have added a FIXME in the code to change this text at a later date if we deem it necessary.

The above branch also handles the case where the user has previously opted-in but later the Ubuntu SSO token is found to have been removed, revoked, or otherwise invalid (in other words, it is always checked now). In this case, the SSO dialog is displayed again and if it it cancelled, the user is opted-out of recommendations and the previous opt-in panel is restored (see bug 973612).

The user can choose to opt-in again at any time.

The only piece remaining to do for *this* bug, then, is to remove the word "anonymous" from the opt-in text. I'll make a second branch (that depends on the branch above) to do that.

Thanks, all!
