Bug description:
SRU information:
[Impact] Accidental creation of multiple UbuntuOne accounts can compromise
the functionality of U1 (whose stack does not support multiple accounts).
The fix consists in disabling (greying out) the "Ubuntu One" item when an
account for it already exists.
[Test Case] With these steps it's possible to create two U1 accounts:
Open **System Settings**.
Go to **Accounts**.
On the **Add Account** section, select **Ubuntu One**.
Enter the email address.
Enter the password.
Click **Continue**.
The **Accounts** screen is shown.
Click **Add account...**
Select **Ubuntu One**.
Enter the email address.
Enter the password.
Click **Continue**.
[Regression Potential] Several packages are involved in this bugfix:
- ubuntuone-credentials: the only changes done here is the addition of a
"<single-account>true</single-account>" line in the ubuntuone.provider XML
file.
This cannot cause any regression (and older versions of libaccounts-glib
simply
ignore any unrecognized elements).
- libaccounts-glib: added a new API to return the value of the
<single-account>
element; also here there's no risk of regression, as applications now using
this
new API are unaffected. Besides, unit tests have been added to cover this
API.
- libaccounts-qt: this is just a thin wrapper around libaccounts-glib. So the
same
API was added here, with unit tests. Other code paths are unaffected by this
change.
- accounts-qml-module: this is a wrapper for libaccounts-qt, to provide a QML
API.
The value of the <single-account> element has been added as a role in the
ProvidersModel class. Again, this doesn't affect the existing
functionality, is
well covered with unit tests and moreover at the current stage the
ProvidersModel
class is known to be used only by the ubuntu-system-settings-online-accounts
project.
- ubuntu-system-settings-online-accounts: support for reading the
<single-account> value
(via accounts-qml-module) and if that is true, then check if there are
already some
accounts created for the given provider. The code changes consists in about
10 lines
of code, and all but one are only triggered if the <single-account> flag is
true
(which happens for the U1 provider only). The code has been tested and
works.
=====================
Original description:
Open **System Settings**.
Go to **Accounts**.
On the **Add Account** section, select **Ubuntu One**.
Enter the email address.
Enter the password.
Click **Continue**.
The **Accounts** screen is shown.
Click **Add account...**
Select **Ubuntu One**.
Enter the email address.
Enter the password.
Click **Continue**.
After adding the first U1 account, the second time you click Add
account, U1 should not be available as an option.
