Completely overhauls the underlying database design:
- referential integrity
- data normalization
- using triggers for various updates to reduce the amount of data logic
in code.
- indexes
- one single database rather than 1 + 1/room
- various structural improvements for useful features such as:
- individually and default-assignable read/write/upload
- time-based permission expiries (e.g. restrict this permission for
x amount of time)
- distinguishing between admins (who can add/remove moderators) and
moderators (who can only moderate but not control the moderator
list)
- global server moderators/admins
- global server bans
- single VIEW for simple querying of a user's effective permissions
(i.e. with database-side coalescing of global/local permissions).
- pinned message via foreign key
- room icon as a regular uploaded file
- per-file file expiries (so that admins/mods can upload non-expiry
files, such as the room icon, or pinned downloads).
- message history so that when messages get edited or deleted a log
is kept of the old value (the idea being that mods would be able
to look this up).
- movable messages (e.g. so there could be a "bad posts" room that
only moderators have access to).
