I'm again replying to a web page, so I apologize for the mail quoting
below.
Hey, I have another GeolocationService question and wonder if
someone could shed some light into the situation. Geolocation.cpp is
invoking GeolocationService::startUpdating, if the
GeolocationService implementation is returning false it is treated
as Permission denied. The questions I have are: - Can lastError be
checked as well? E.g. there might be no provider and the service
just returned false because of that? - Should the error message move
to LocalizedStrings? - If one looks at the mozilla mockup/
implementation the permission check might go through the
userinterface. Which means we might want to do something like we do
in the FrameLoaderClient for policy checks?
I think your questions here are more applicable to the geolocation
mailing list, which you can find linked via the Geoloation spec.
My answers:
1) lastError will be set when there is an error, so in this case it
will be set for PERMISSION_ERROR.
2) The discussion on the mailing list is that the error message is not
localized and pretty much only for developers. (See the latest
10/27/2008 for the wording).
3) The geolocation spec allows the native platform code to determine
and display UI for permission checks. There is discussion on the
mailing list now whether or not this is correct. Personally, I think
it is correct. If this spec starts to mandate UI, it may diverge from
the platform's UI for location permission / security. This will dilute
the security, because it doesn't match what the platform itself may
mandate.
Thanks,
