This commit changes when the sweep pkscript
is assigned in the construction of the justice
transaction. Currently, the sweep pkscript is
assigned when the task is bound to a session.
However, we will moving to an assignment where
a unique sweep pkscript is used per channel to
prevent address inflation. Hence, this commit
makes the sweep pkscript a state dependent
variable, since it can be known at the time the
channel id is assigned.
A recent change in this area of the codebase refactored some code to
make way for the deprecation of the streaming multi-route `SendToRoute`
method. Along the way, it removed the parsing of the `PaymentHashString`
field for the sync `SendToRouteSync` which is meant to be used via the
REST interface. In this commit, we fix this by populating _both_
`PaymentHash` and `PaymentHashString`. This is OK, as
`extractPaymentIntent` will check both values to extract the hex-encoded
payment hash if it's specified.
In this commit, we modify the main interface-level tests for neutrino to
skip the block catch up re-org test. We do this, as the test itself is
very unstable and only passes occasionally by the grace of RNGesus.
What's needed to ensure it passes reliably is to extend neutrino with a
cache of the last N blocks disconnected. Sample output of the affected
test when run:
```
--- SKIP: TestInterfaces/neutrino_test_catch_up_on_missed_blocks_w/_reorged_best_block (0.00s)
interface_test.go:1574: skipping re-org test for neutrino
```
Because the integration tests are already long-running, it is preferable to
add testing for the RPC channel update subscription to an existing test rather
than adding additional tests.
This function will be used in the switch to retrieve the channel point for a link,
allowing the switch to retrieve individual channels from the database.
This commit introduces the channel notifier which is a central source
of active, inactive, and closed channel events.
This notifier was originally intended to be used by the `SubscribeChannels`
streaming RPC call, but can be used by any subsystem that needs to be
notified on a channel becoming active, inactive or closed.
It may also be extended in the future to support other types of notifications.
`createRPCChannel` is used by the `listchannels` RPC call and will be
used by `subscribechannels` as well.
`createRPCClosedChannel` is used by the `closedchannels` RPC call and
will also be used by `subscribechannels`.
This is used by the `listchannels` RPC call and will be used by
`subscribechannels` as well. Its purpose is to mitigate code duplication
between the two RPC calls.
To ensure a call to ConnectToPeer doesn't block the agent from
shutting down, we'll launch it in a non-waitgrouped goroutine, that
will signal when a result is returned.
