<div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> There's a "valid_until" gconf-key that needs to be set to a value higher than current time, or the backend won't emit the signals. I'm still open to other, more generic solutions.</blockquote><div> I think the valid until, is an interesting idea.   I don't think it should stop emitting the position after the valid time, but rather have an significant increase in error.  </div> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Todo list: * Implement service_changed signal emission * Add gconf schemas * refactor (it's fairly rough right now, but I wanted it in so    Keith won't break my tree with more API changes :) Some observations about API changes: * civic location method/signal should have timestamp argument too? </blockquote><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> * I assume timestamp is time of original data retrieval,    in case of manual backend that would be when user inputs the data? * Maybe current_position should actually work like "last_position":    always return the last valid position and let the client check if    timestamp is acceptable? If clients are interested in current data,    they should subscribe to signals anyway... The function should be    renamed though: "current" just doesn't describe this behaviour.</blockquote><div> This is an interesting idea.   I believe this is what I intended with the timestamps.   I believe the more we work with this, the more we find that multiple backends will be needed to find a good location.   I believe timestamps will help us make the 'geoclue-master' arbitrator much easier.
