| 1 Account based MUC joining | |
| 2 ========================= | |
| 3 | |
| 4 Normally when joing a MUC groupchat, it is each individual client that | |
| 5 joins. This means their presence in the group is tied to the session, | |
| 6 which can be short-lived or unstable, especially in the case of mobile | |
| 7 clients. | |
| 8 | |
| 9 This has a few problems. For one, for every message to the groupchat, a | |
| 10 copy is sent to each joined client. This means that at the account | |
| 11 level, each message would pass by once for each client that is joined, | |
| 12 making it difficult to archive these messages in the users personal | |
| 13 archive. | |
| 14 | |
| 15 A potentially better approach would be that the user account itself is | |
| 16 the entity that joins the groupchat. Since the account is an entity that | |
| 17 lives in the server itself, and the server tends to be online on a good | |
| 18 connection most of the time, this may improve the experience and | |
| 19 simplify some problems. | |
| 20 | |
| 21 This is one of the essential changes in the MIX architecture, which is | |
| 22 being designed to replace MUC. | |
| 23 | |
| 24 `mod_minimix` is an experiment meant to determine if things can be | |
| 25 improved without replacing the entire MUC standard. It works by | |
| 26 pretending to each client that nothing is different and that they are | |
| 27 joining MUCs directly, but behind the scenes, it arranges it such that | |
| 28 only the account itself joins each groupchat. Which sessions have joined | |
| 29 which groups are kept track of. Groupchat messages are then forked to | |
| 30 those sessions, similar to how normal chat messages work. | |
