308: Close bad connections to takers r=thomaseizinger a=thomaseizinger
- Introduce dedicated actor for forwarding only `Ok` messages
- Close connections with takers that don't adhere to the message format
Co-authored-by: Thomas Eizinger <thomas@eizinger.io>
Upon rejection, we always have to remove the order on the maker side, otherwise a taker cannot re-try taking (with e.g. a different amount) because there is already a rejected cfd in the taker database.
331: Fix default quantity in UI r=bonomat a=bonomat
`@thomaseizinger` : I'm not sure if I understand it correctly. Can I do ed2ec8eb49 or is this not allowed because I change the variable independent of what is in the state?
Alternative solution is the second commit ac8d6e191cresolves#330

322: Cleanup in Cfd actors r=klochowicz a=klochowicz
I started out trying to fix a common gotcha (forgetting to refresh Cfd feed),
and then realised that I was not far off of addressing a bunch of TODOs in the code

332: Provide margin of counterparty r=bonomat a=bonomat
Very useful for the maker.
Not shown in the UI for now.

329: Set default log level for whole crate r=da-kami a=bonomat
Resolves#325
We were setting a filter for the binaries only and the rest was on INFO.

321: Use `MessageChannels` in `maker_inc_connections::Actor` r=luckysori a=luckysori
We would have liked to attach the stream of `TakerStreamMessage`s directly to the `MessageChannel`, but we failed and instead decided to let the `maker_inc_connections::Actor` send these messages to itself and then forward them to the `maker_cfd::Actor`.

I wasted a lot of time trying to send the message directly to the `maker_cfd::Actor`. I trust that `@thomaseizinger` can find a way, but I had to give up 😞

Inserting cfd or updating its state requires a follow-up update on the Cfd feed
sent to the UI. Encapsulate the behaviour in functions that are shared
across Cfd actors.
307: Setting boundaries r=bonomat a=bonomat
This improves the UX slightly as the user knows what is the min and max amount.
The UI will default to min amount.

318: Introduce a `fan_out::Actor` instead of iterating in the `oracle::Actor` r=thomaseizinger a=thomaseizinger
A fan-out actor takes an incoming message and forwards it to a set
of actors. This allows our `oracle::Actor` to be unaware, how many
other actors are interested in the attestation, thus simplifying it.

315: Lock in profit on collaborative close price r=da-kami a=da-kami
fixes#312
Once we have collaborative close present in the state(s) we lock in the profit based on the price of the collaborative close.
Note: Currently no automated validation on the maker side if the given amounts and price of collaborative settlement are sane.

Once we have collaborative close present in the state(s) we lock in the profit based on the price of the collaborative close.
Note: Currently no automated validation on the maker side if the given amounts and price of collaborative settlement are sane.
Simplify model's state machine as PendingClose only matters for the UI
(for user feedback & available actions).
Disallow proposing another settlement if one was already signed.
295: Db refactor r=thomaseizinger a=DeliciousHair
DB code refactoring for #88
The primary goal was to remove all of the calls to `serde_json::to_string()` for the data-handling, thus enabling us to do (more or less):
```rust
Order {
row.column,
...
}
```
as well as clean up the SQL for easier reading. This has mostly been accomplished, with further refinements easily accomplished once the upstream issues in `sqlx` are addressed. See #314
for issues we are tracking.

Anything that can fail (e.g. fetching oracle stuff) has to be tried before we change any state or notify the taker, otherwise it can happen that we remain in a failed state that causes very weird side effects.
313: Replace `Address` with `MessageChannel` in some key places r=luckysori a=luckysori
We may need to use `MessageChannel` instead of `Address` elsewhere (perhaps everywhere), but these definitely need to change.

Work towards #231

The `oracle::Actor` only needs to be able to send the
`oracle::Attestation` to an actor who can handle it. We were already
able to express this using trait bounds, but it was blocking us from
being able to make the `{maker_taker}_cfd::Actor` generic over
different actors due to infinite, cyclic types.
The `monitor::Actor` only needs to be able to send the
`monitor::Event` to an actor who can handle it. We were already able
to express this using trait bounds, but it was blocking us from being
able to make the `{maker_taker}_cfd::Actor` generic over different
actors due to infinite, cyclic types.
306: Borrow CfdState when updating state in the database r=klochowicz a=klochowicz
The function signature didn't need to take the whole state, as it was only
borrowed internally.
Removes the need for many `.clone()` calls sprinkled in the codebase.
