Refresh channel memory state whenever the short channel id is refreshed.
This is to make the in-memory channel consistent with the disk data.
Fixes#3765.
This prepares for routing to self. When checking the condition at the
start, the loop would terminate immediately because the source is equal
to the target.
This commit restructures an invoice's ContractTerms to better encompass
the restrictions placed on settling. For instance, the final ctlv delta
and invoice expiry are moved from the main invoice body (where
additional metadata is stored). Additionally, it moves the State field
outside of the terms since it is rather metadata about the invoice
instead of any terms offered to the sender in the payment request.
This fixes an issue that would lead to a flake during intergration
tests. Carol would start up with a outdated state and attempt to force
close the channel. At the same time she would connect to Dave,
triggering the dataloss protection. Dave would respond by force closing
the channel, and Dave transaction would in some cases have a higher fee,
resulting Carol's tx being replaced.
We fix this by suspending Dave until Carol's close tx is mined.
In this commit, we update the `AbandonChannel` method to also remove the
state from the countract court as well as the channel graph. Abandoning
a channel is now a three step process: remove from the open channel
state, remove from the graph, remove from the contract court. Between
any step it's possible that the users restarts the process all over
again. As a result, each of the steps below are intended to be
idempotent.
We also update the integration test to assert that no channel is found
in the graph any longer. Before this commit, this test would fail as the
channel was still found in the graph, which can cause other issues for
an operational daemon.
Fixes#3716.
In this commit, we export the `ResolveContract` method as it's useful as
a way to manually remove active contracts from the chain and channel
arbitrator. Along the way, we also update the method to also attempt to
stop the channel arb if it exists. This allows an external party to
remove all state with a single call. Before this commit, it was assumed
that this method was only called by the channel arb itself, when it was
already on the way to exiting after all contracts were fully resolved.
We also add a set of unit tests to exercise the intended behavior as
this method is now public.
This commit modifies the FetchPayment method to return MPPayment structs
converted from the legacy on-disk format. This allows us to attach the
HTLCs to the events given to clients subscribing to the outcome of an
HTLC.
This commit also bubbles up to the routerrpc/router_server, by
populating HTLCAttempts in the response and extracting the legacy route
field from the HTLCAttempts.
