[sr-dev] mysql driver support for presence notifier processes?

i asked on dev irc meeting if mysql driver now (4.0 or master) supports the features needed by presence notifier processes. this was discussed in march on thread: http://lists.sip-router.org/pipermail/sr-dev/2013-March/018946.html i'm also a bit puzzled, why there is no DB_CAPABILITY that would tell if the required features are implemented by the underlying db driver. now it seems to be possible to have notifier_processes > 0 even if the underlying db driver cannot handle them properly. does anyone know what the current status of this is? -- juha
