mod_smacks: also count outgoing MAM messages mod_smacks doesn't count outgoing MAM messages, which causes warnings in Prosody such as: > The client says it handled 41 new stanzas, but we only sent 2 It seems mod_smacks is in the wrong here and that it's too strict in trying to determine what is a valid stanza to count. In RFC6120: > Definition of XML Stanza: An XML stanza is the basic unit of meaning > in XMPP. A stanza is a first-level element (at depth=1 of the stream) > whose element name is "message", "presence", or "iq" and whose > qualifying namespace is 'jabber:client' or 'jabber:server'.

Account based MUC joining
=========================

Normally when joining a MUC groupchat, it is each individual client that
joins. This means their presence in the group is tied to the session,
which can be short-lived or unstable, especially in the case of mobile
clients.

This has a few problems. For one, for every message to the groupchat, a
copy is sent to each joined client. This means that at the account
level, each message would pass by once for each client that is joined,
making it difficult to archive these messages in the users personal
archive.

A potentially better approach would be that the user account itself is
the entity that joins the groupchat. Since the account is an entity that
lives in the server itself, and the server tends to be online on a good
connection most of the time, this may improve the experience and
simplify some problems.

This is one of the essential changes in the MIX architecture, which is
being designed to replace MUC.

`mod_minimix` is an experiment meant to determine if things can be
improved without replacing the entire MUC standard. It works by
pretending to each client that nothing is different and that they are
joining MUCs directly, but behind the scenes, it arranges it such that
only the account itself joins each groupchat. Which sessions have joined
which groups are kept track of. Groupchat messages are then forked to
those sessions, similar to how normal chat messages work.
