When using MPP, if we can't find a route, we need to add an entry to the
DB. Otherwise when users query their payment status, nothing will be
returned which is a bad UX.
Fixes#1512
The channelstats API only returns results for the *outgoing* channels
used when relaying. We must also include the *incoming* channels, otherwise
it looks like they're inactive which doesn't reflect their real usage.
Fixes#1465
* Extract faulty channels selection from PaymentLifecycle
Move the logic of figuring out which channels/nodes should be ignored
when retrying after a payment failure out of the PaymentLifecycle.
We can figure this out looking only at the `PaymentFailure` generated,
and the multi-part logic could leverage these helpers.
* Refactor RouteResponse
It was useless to return `ignoreNodes` and `ignoreChannels`, it's rather
the responsibility of the caller (PaymentLifecycle) to store and update
these sets.
Preparing for the MPP move inside the router, we introduce a Route class
and let RouteResponse return a collection of Routes.
This creates some ugliness in PaymentLifecycle because of the `routePrefix`,
but this is just temporary: the `routePrefix` "hack" will be removed soon.
This is almost a drop-in replacement. I had to relaxed compiler
parameters to allow deprecated features though.
Main changes:
- relaxed compiler parameters to minimize impact (e.g. allow
deprecated features)
- `scala.collection.JavaConverters` -> `scala.jdk.CollectionConverters`
- `MultiMap` -> `MultiDict`
Compilation is 25% faster on my machine, compiler is a bit more strict
(it found an "invalid comparison" bug).
Do all the changes that will be required and are already possible to
minimize the diff:
- update dependencies
- `'something` -> `Symbol("something")`
- `BigDecimal.xValue()` -> `BigDecimal.xValue`
- `Map.filterKeys` -> `Map.filterKeys.toMap` (same for `Map.mapValues`)
- `def myMethod(...)` -> `def myMethod(...): Unit`
