[pneubeck (no reviews), 2014/08/06 19:52:06]

maybe reword 'effective policy is set'. I'm not sure what that should mean.

maybe, 'if the policy is effective' ?

[stevenjb, 2014/08/06 20:22:52]

Made that part more explicit.

nit: now this one can be inlined into the assignment to recommendedValue.

copy&paste error:
UserSetting -> DeviceSetting

[stevenjb, 2014/08/06 20:22:52]

Shouldn't this still be 'UserSetting' if the effective setting was set by the
user?
 

[pneubeck (no reviews), 2014/08/06 20:52:57]

Damn it. I meant SharedSetting.
But as you're always setting UserSetting in the C++ side, this should be ok for
now.
SharedSetting is the equivalent of UserSetting for shared networks.

Just keep UserSetting for now.

[stevenjb, 2014/08/06 21:20:28]

I'd like to get this right for when we call this with the results of
GetManagedProperties also. I will follow up in email.

[stevenjb, 2014/08/06 21:43:19]

OK, I changed the .cc code and checked for SharedSetting here.

Question: Would these be more accurate as:
  if (effective == {User|Device}Policy)? i.e. would a recommended value ever
have Effective set to anything else?

[pneubeck (no reviews), 2014/08/07 17:28:58]

There is no other Effective value, but Effective could be unset if neither
policy nor user set property.
CoreOptionsHandler doesn't set the controlledBy to recommended in that case. So
you could change it to 'effective == UserPolicy' and accordingly 'effective ==
DevicePolicy'.

+          event.value.controlledBy = 'recommended';
+        event.value.recommendedValue = deviceValue;
+      } else if (effective == 'UserPolicy' || effective == 'DevicePolicy') {
+        event.value.controlledBy = 'policy';
+      }
