Can register an account with the bot to manage variables and stuff in
private room, and then separately "link" it with a password, which
makes it available to anything using the bot API (aka web app). Can
also unlink and unregister. Check command no longer validates
password. It just checks and reports your account status.
Instead of automatically creating a user account entry for any user
executing a command, we use an Account enum which covers both
registered and "transient" unregistered users. If a user registers,
the context has the actual user instance available, with state and
everything. If a user is unregistered, then the account is considered
transient for the request, with only the username available.
- Adds a user_state table, currently only with active_room.
- A user must have an account to take advantage of state.
- Now, all users will get an 'account' even if they don't explicitly register.
- Bonus: converts user queries to compile-time checked macros.
To support these automatically created "accounts," the accounts table
now also has an account_status column, indicating if the user is
registered or not (or pending activation--future use).
The User model has been updated with extra properties from the state,
and the user is now carrried in the Context during command execution.
A user is ensured to be created before executing the command.
- If the room is end-to-end encrypted.
- If only the sending user and the bot are present in the room.
This lays groundwork for sensitive commands like registering a user
account with the bot.
This upgrade introduces a handful of breaking changes in the Rust
Matrix SDK.
- Some types have disappeared and changed name.
- Some functions are no longer async.
- Room display name now has a Result type instead of just returning
the value.
- Client state store has breaking changes (not really a big deal).
This required introduction of a new type to store room information
that we are interested in on the context struct. This new RoomContext
is required mostly due to unit tests, because it is no longer possible
to instantiate the Room type in the Matrix SDK.
The database API for user variables has changed somewhat again, this
time closer to the proper vision. There are now two separate sled
Trees in the Variables struct, one for user-defined variables, and one
for counts. Keys have been changed to be username-first, then room ID.
The signatures of the functions now also use a strongly-typed struct,
UserAndRoom.
As part of this, the Context object now once again avoids allocating
new strings.
Other random changes included here:
- Remove tempfile crate in favor of sled temporary db config.
- Add bincode crate in anticipation of future (de)serializing.
This commit introduces the Sled embedded key-value store for keeping
track of user variables on a per-room basis. Extensive changes were
made to the command module to separate concerns and also pass the
database "connection" down the line.
- A new "Context" object was created to hold information and state
needed for command execution (namely the database).
- Database is very simple for now, storing only user variables.
Refactoring later for storing more complicated types.
- State actor moved into Actors struct, in preparation for either
more actors, or ripping the whole thing out entirely.
- Other modules are also more properly separated, notably
the config module is entirely self-contained.
