Please run `dbus-monitor` on a KDE system now and then, to see all the DBus communication coming out of nepomuk (I suppose this is especially happening now because the akonadi_nepomuk_feeder agent is indexing all the existing email).
I see this, in particular: for every property, propertyAdded is emitted, followed by propertyChanged. Surely a single signal could be used for this? signal sender=:1.3181 -> dest=(null destination) serial=7023161 path=/resourcewatcher/watch27069; interface=org.kde.nepomuk.ResourceWatcherConnection; member=propertyAdded string "nepomuk:/res/4efdbd00-0b8a-44fe-bc8a-061966bdb2d9" string "http://www.semanticdesktop.org/ontologies/2007/03/22/nmo#isRead"; array [ variant boolean false ] signal sender=:1.3181 -> dest=(null destination) serial=7023162 path=/resourcewatcher/watch27069; interface=org.kde.nepomuk.ResourceWatcherConnection; member=propertyChanged string "nepomuk:/res/4efdbd00-0b8a-44fe-bc8a-061966bdb2d9" string "http://www.semanticdesktop.org/ontologies/2007/03/22/nmo#isRead"; array [ variant boolean false ] array [ ] Another example, to show it's not related to "isRead": signal sender=:1.3181 -> dest=(null destination) serial=7023137 path=/resourcewatcher/watch27069; interface=org.kde.nepomuk.ResourceWatcherConnection; member=propertyAdded string "nepomuk:/res/4efdbd00-0b8a-44fe-bc8a-061966bdb2d9" string "http://www.semanticdesktop.org/ontologies/2007/08/15/nao#prefSymbol"; array [ variant string "nepomuk:/res/f36a5df4-7000-4678-9c71-1644ab76da00" ] signal sender=:1.3181 -> dest=(null destination) serial=7023138 path=/resourcewatcher/watch27069; interface=org.kde.nepomuk.ResourceWatcherConnection; member=propertyChanged string "nepomuk:/res/4efdbd00-0b8a-44fe-bc8a-061966bdb2d9" string "http://www.semanticdesktop.org/ontologies/2007/08/15/nao#prefSymbol"; array [ variant string "nepomuk:/res/f36a5df4-7000-4678-9c71-1644ab76da00" ] array [ ] For #prefLabel I even saw the nepomukstorage process emit propertyAdded+propertyChanged 6 times in a row, for the same resource, with the same label. -- David Faure, [email protected], http://www.davidfaure.fr Working on KDE, in particular KDE Frameworks 5 _______________________________________________ Nepomuk mailing list [email protected] https://mail.kde.org/mailman/listinfo/nepomuk
