Or is there some other better way? MarkI'm not part of the Gnome team, but I think it might be a better idea to create some a daemon which listens for simple push and then uses dbus to communicate the notification. Back of the napkin math looks thusly: App is installed: App sends a message to dbus telling the daemon to Register with a PushServer Daemon receives an Endpoint from the Push server and sends a message via dbus App receives an Endpoint from dbus and sends this to the App Server Message is Received: Daemon receives the message and extracts the UAID Daemon sends the message on dbus DBus routes the message to the app based on the UAIDof the message App is uninstalled: App sends a notification to dbus. Dbus routes the message to the daemon Daemon unregisters the app App is garbage collected: It would be reasonable for the SimplePush daemon to periodically review which apps have consumed push messages and unregister applications which haven't been used in a while. You're right Summers, it would be better for there to be a SimplePush daemon for various OSes, which under Linux would generate dbus messages that Gnome can display. By "App" do you mean a desktop application program? Aren't alerts for these working already, such as the new-email alerts sent by Thunderbird? The new thing here is to allow users to request alerts from websites and have them delivered to the desktop even if the website is not open, and even if a browser is not open. Given the existence of a SimplePush service such as the one run by Mozilla, and a SimplePush daemon that listens for notifications from the service and delivers notifications via dbus, all you need is to give browsers the ability to register notifications with the service, and give websites the ability to push notifications to the service. Only Firefox can currently do this, and I'm not sure they'd be willing to run notification servers that can be used by non-Mozilla browsers and desktops. Perhaps the solution is just to make available dbus daemons for commercial alert offerings like AlertRocket and XendApp. Or instead some open standard with servers hosted by some giant like Google.

Previously when on OSX, my notifications sidebar would show me all the new messages and alerts from this website (running inside Safari). I think this would be a neat feature to have when combined with the Messages tray in GNOME 3. Perhaps, this should have come up as GSoC project idea? Sindhu, it looks like the alerts built into Webkit-derived browsers like Chrome and Safari -- which is a draft standard (http://www.w3.org/TR/notifications) -- only gives these browsers the ability to show alerts outside their windows, such as on the desktop when the browser is minimised. The browser still needs to be running, and unlike SimplePush there's no mechanisms defined for alerts to be registered, or delivered when the webpage isn't open. Mark |
