Ok. I tend to agree. Another factor is also that a specific "app launched" event also fits better in a semantic world where we share data with Tracker. >From a technical POV it is however not possible to write a generic DP by using a GIO extension point hook for AppInfo.launch(). As I also mentioned on IRC the extension point code has no way of knowing which app it's running inside. Michal mentioned that we could use getpid() -> bamfdaemon to look up the .desktop file for the app we run inside, but I am not very happy about that prospect. As the GApplication/GtkApplication APIs are still in the making we may be able to influence them so that you pass the desktop id of your app in the constructor. I'll talk to the G/Gtk guys about this... -- Refuses to log events without subjects https://bugs.launchpad.net/bugs/620109 You received this bug notification because you are a member of Zeitgeist Framework Team, which is subscribed to Zeitgeist Framework. Status in Zeitgeist Framework: New Bug description: Zeitgeist says: Traceback (most recent call last): File "/usr/share/zeitgeist/_zeitgeist/engine/main.py", line 497, in _insert_event_without_error return self._insert_event(event, sender) File "/usr/share/zeitgeist/_zeitgeist/engine/main.py", line 508, in _insert_event raise ValueError("Illegal event format: No subject") ValueError: Illegal event format: No subject If I send it an event without a subject. The reason why I am doing that is because I am trying to log whenever an app is launched. Like for instance when I launch the Gnome calculator. This way I can have "most popular apps" listings and what not :-) So my request: Can we lax the requirement for events to have a subject? _______________________________________________ Mailing list: https://launchpad.net/~zeitgeist Post to : zeitgeist@lists.launchpad.net Unsubscribe : https://launchpad.net/~zeitgeist More help : https://help.launchpad.net/ListHelp
