When compacting the update logs we remove any fee updates when they
remove height is passed. We do this since we'll assume fee updates are
added and removed at the same commit height, as they will apply for all
commitments following the fee update.
This commit adds conversion between the lnwire.UpdateFee message and the
new FeeUpdate PaymentDescriptor. We re-purpose the existing Amount field
in the PaymentDescriptor stuct to hold the feerate.
This commit adds a new updateType that can be used for
PaymentDescriptors: FeeUpdate. We repurpose the fields of the existing
PaymentDescriptor struct such that we can easily re-use the commit/ack
logic used for other update types also for fee updates.
Since NodeScores no longer returns fully populated AttachmentDirectives,
we make this explicit by defining a new type NodeScore that includes a
subset of what the AttachmentDirective does.
We create a new type NodeScore which is a tuple (NodeID, score). The
weightedChoice and chooseN algorithms are altered to expect this type.
This is done in order to simplify the types we are using, since we were
only using a subset of the fields in AttachmentDirective.
Since we want to combine scores from multiple heuristics, things get
complicated if the heuristics report their own individual channel sizes.
Therefore we change the NodeScores interface slightly, letting the agent
specify the wanted channel size, and let the heuristic score the nodes
accordingly.
We let the agent call ChannelBudget on its constraints directly, and
not go through the heuristic. This is needed since when we want to have
multiple active heuristics concurrently, it won't make sense anymore to
ask each of the heuristics.
The mockConstraints are also updated to act as the mockHeuristic did
before, by making it possible to control the responses it gives by
sending them on the contained channels.
To decouple the autopilot heuristic from the constraints, we start by
abstracting them behind an interface to make them easier to mock. We
also rename them HeuristicConstraints->AgentConstraints to make it clear
that they are now constraints the agent must adhere to.
In this commit, we ensure that when we read node aliases from the wire,
we ensure that they're valid. Before this commit, we would read the raw
bytes without checking for validity which could result in us writing in
invalid node alias to disk. We've fixed this, and also updated the
quickcheck tests to generate valid strings.
In this commit, we extend the DerivePrivKey method to allow callers that
don't know the full KeyLocator information to attempt to derive a
private key via a brute force mechanism. If we don't now the full
KeyLoactor, then given the KeyFamily, we can walk down the derivation
path and compare keys one by one. In order to ensure we don' t enter an
infinite loop when given an unknown public key, we cap the number of
keys derived at 100k.
An upcoming feature to lnd that adds static channel backups will utilize
this feature, as we need to derive the shachain root given only the
public key and key family, as we don't currently store this KeyLocator
on disk.
This commit is a preparation for the addition of new invoice
states. A database migration is not needed because we keep
the same field length and values.
In this commit, we address an issue with the FetchWaitingCloseChannels
method where it would not properly return channels that are unconfirmed
and also have an unconfirmed closing transaction because they were
filtered out. We fix this by fetching channels that remain unconfirmed
that are also waiting for a confirmed closing transaction.
This will allow the recently added test TestFetchWaitingCloseChannels to
pass.
