Bug 24506 – Geolocation in Safari differs from the spec, no Coordinates attribute on Position

• Component: WebCore JavaScript
• Status: RESOLVED FIXED

[Greg Bolsinga]

The spec at http://dev.w3.org/geo/api/spec-source.html specifies that there should be a Coordinates attribute (coords) on the Position interface, which encapsulates lat, long, altitude, accuracy, etc.  But our version doesn't have the Coordinates attribute.  In our implementation, lat, long, accuracy, etc are attributes on Position.

From the spec:

"The Position interface is the container for the geolocation information returned by this API. This version of the specification allows one attribute of type Coordinates and a timestamp. Future versions of the API may allow additional attributes that provide other information about this position (e.g. street addresses).

  interface Position {
    readonly attribute Coordinates coords;
    readonly attribute DOMTimeStamp timestamp;
  };

The coords attribute contains a set of geographic coordinates together with their associated accuracy, as well as a set of other optional attributes such as altitude and speed.

The timestamp attribute represents the time when the Position object was acquired and is represented as a DOMTimeStamp [DOMTIMESTAMP].

Coordinates interface

  interface Coordinates {
    readonly attribute double latitude;
    readonly attribute double longitude;
    readonly attribute double altitude;
    readonly attribute double accuracy;
    readonly attribute double altitudeAccuracy;
    readonly attribute double heading;
    readonly attribute double speed;
  };
 "

This patch implements the needed changes

This add a Coordinates method to the Position in Geolocation.

[Greg Bolsinga]

It is also missing PositionOptions.maximumAge.

r=me, looks good.

Geolocation related sources would probably deserve a subdirectory of their own at some point.
