This commit extends the RPC interface with GetNodeMetrics will contain
all graph node metrics in the future. Currently only holds betweennes
centrality per node.
This commit adds betweenness centrality to the available node metrics.
Betweenness centrality is a per node centrality measure which for an
arbitrary node v equals to the sum of shortest paths going trough v
divided by the number of all shortest paths for for each vertex pair
k, s where k != s != v.
This commit adds the NodeMetric interface which will be used for all
graph metrics not directly part of the autopilot but are useful in
composite heuristics to drive autopilot decisions and improve node
scores.
This commit changes the switch to only log an error if update_fail_htlc
comes in and closeCircuit returns ErrUnknownCircuit. Rationale
being that only settles should hit this code path, anything else
is a result of a link flap and should be treated as an error.
This commit modifies updateCommitTx to error with ErrLinkShuttingDown
when we try to send a ContractUpdate on the htlcUpdates chan and the
link has closed the quit chan. It also changes the order of the call
to ackDownStreamPackets and contract update call for consistency since
the packets should be acknowledged before the link goes down.
This commit changes the fallback in NextLocalHtlcIndex to
RemoteCommitment since the LocalHtlcIndex field lags behind
on the LocalCommitment. Without this bug fix, open circuits
would get prematurely trimmed, resulting in more erroneous
logs. A test case is included to check that the fix works.
The pending closing channels field was present to cover an edge case
where coperatively closed channels were closed before upgrade and
confirmed after the upgrade. This commit deprecates the field and adds
a warning log to cover these edge cases.
In this commit, we make the internal channel funding flow aware of
frozen channels. We also update the testSingleFunderReservationWorkflow
method to ensure that the created channels have the proper type bit set.
As frozen channels can only be created via the non-default channel
assembler, we extend both the ShimIntent and CannedAssembler to also
accept and expose this new channel status along with the thaw height.
In this commit, we add a new channel type bit: a frozen channel. A
frozen channel is one that can only be cooperatively closed by the
responder, but not the initiator. This channel type is useful for
certain classes of channel factory like protocols. We then add a new key
on the channel bucket level to store the height after which this
restriction no longer applies.
