Description Xavier Claessens 2013-09-17 21:04:40 UTC

+++ This bug was initially created as a clone of Bug #69474 +++

In Gabble, contacts not on our roster have UNKNOWN presence (e.g. see Bug #25583). In Haze, asking for their presence is an error.

This is especially problematic in Telepathy 1.0, where the presence mixin's get_statuses() callback can no longer fail.

Salut does not have UNKNOWN presence, but its OFFLINE presence is already a dummy one...

To be more precise, I think that OFFLINE should not exist in salut and replaced by UNKNOWN. no ?

I don't think so. My mental model is that in mDNS, my local LAN is analogous to the server (or network of federated servers) in a centralized protocol - so anyone I can see is online, and everyone else is offline. There's no such thing as "I can't see that you're online, but maybe I don't have permission to do so?"

Perhaps you're online on *your* local LAN, but in my mental model, that's a different "server", and on *my* "server", you're definitely offline. (Replace "my local LAN" with "Freenode" and "your local LAN" with "OFTC", or Facebook and Windows Live, or any other pair of non-cooperating services.)

The reason why non-buddies on a conventional IM network should be UNKNOWN is that we can't authoritatively say "Fred is online"/"Fred is offline" if we wouldn't receive his presence anyway. That doesn't apply to Salut.

Something that *does* apply to Salut is that GetPresences() should always return *something* for any valid handle, i.e. if you call the TpPresenceMixinGetContactStatusesFunc with valid handles (which it may, and should, assume), it should always succeed and return a presence per contact. In next, it no longer has its GError argument.
