I've been investigating the issue a bit. My understanding of the situation is that Chromium (used by oxide) keeps its own cache for last known location, and that's what it uses when the client plays with the "maximumAge" option; otherwise, it assumes that the location provider always returns new positions. The interface it offers to let developers implement custom location providers (and which oxide uses to implement its QtPositioning-based backend) is this one:
https://chromium.googlesource.com/chromium/chromium/+/trunk/content/public/browser/location_provider.h As you can see, it doesn't offer a way to let custom implementations specify a last known position. Some time ago, I made a change to the location service which makes it always return the last known position as soon as a client starts requesting updates: http://bazaar.launchpad.net/~phablet-team/location- service/15.04/revision/204 The plan was to obfuscate that location update and also to decrease its accuracy as it ages (and indeed, not report a position at all if so much time has passed that the user could be anywhere now), but this hasn't been implemented yet. Also, as this bug report says, we probably should not return a cached position to a client which has just been authorised to use the location service. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to location-service in Ubuntu. https://bugs.launchpad.net/bugs/1551686 Title: browser leaks old location data to web pages To manage notifications about this bug go to: https://bugs.launchpad.net/oxide/+bug/1551686/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
