Resolved by always normalizing JIDs to bare form, regardless of if they
are JID objects or strings.
Also simplified related code to prefer use of JID objects instead of
strings so they don't need to be parsed multiple times.
This was XEP-0237, but is now part of RFC 6121.
Roster backends should now expose two additional methods:
version(jid):
Return the version of the given JID's roster.
set_version(jid, version):
Update the version of the given JID's roster.
A new state field will be passed to the backend if an item
has been marked for removal. This is 'removed' which will
be set to True.
As part of adding this feature:
- fixed bug in update_caps() not assigning verstrings
- fixed xep_0004 typo
- can now use None as a roster key which will map to boundjid.bare
- fixed using JID objects in disco node handlers
- fixed failing test related to get_roster
Several of these bugs I've fixed before, so I either didn't push them
earlier, or I clobbered something when merging. *shrug*
The change to using the new roster broke the original auto_* values
and used per-roster versions. The original auto_* values will now set
the behaviour globally. Use the per-roster values to override for a
specific JID.
Can now use len(self.client_roster) to get the number of JIDs in
the roster, and self.client_roster.groups() to get a dict of
groups and the JIDs in those groups.
