In this commit, we fix a bug that prevents us from sending custom
records to nodes that aren't in the graph. Previously we would simply
fail if we were unable to retrieve the node's features.
To remedy, we add the option of supplying the destination's feature bits
into path finding. If present, we will use them directly without
consulting the graph, resolving the original issue. Instead, we will
only consult the graph as a fallback, which will still fail if the node
doesn't exist since the TLV features won't be populated in the empty
feature vector.
Furthermore, this also permits us to provide "virtual features" into the
pathfinding logic, where we make assumptions about what the receiver
supports even if the feature vector isn't actually taken from an
invoice. This can useful in cases like keysend, where we don't have an
invoice, but we can still attempt the payment if we assume the receiver
supports TLV.
This commit allows custom node features to be populated in specific test
instances. For consistency, we auto-populate an empty feature vector for
nodes that have nil feature vectors before writing them to the database.
Previously we would return nil features when we didn't have a node
announcement or a given node. With this change, we can always assume the
feature vector is populated during pathfinding.
Adds a global Authenticate method that can be used to get the
atuhentication options needed to call the grpc server.
Currently meant only for used with the mobile bindings, so we use the
admin macaroon.
Earlier we used emtpy grpc server options if custom listeners were set.
This was done to disable TLS. Now, we reuse the same server options as
for the regular listeners, in a move towards enabling TLS also here.
This commit allows sweeper to sweep inputs that on its own are not able
to form a sweep transaction that meets the dust limit.
This functionality is useful for sweeping small outputs. In the future,
this will be particularly important to sweep anchors. Anchors will
typically be spent with a relatively large fee to pay for the parent tx.
It will then be necessary to attach an additional wallet utxo.
A refactoring that introduces no functional changes. This prepares for
the addition of wallet utxos to push the sweep tx above the dust limit.
It also enabled access to input-specific sweep parameters during tx
generation. This will be used in later commits to control the sweep
process.
This commit addresses a bug in the channel event store
where the opened time of a channel event log was not
set for peers that were offline on startup.
Previously, opened time was set to the time of the first
event in the event log. This worked for online peers,
because the eventlog was created with an initial online
event. However, offline peers had no inital event so had
no open time set.
This commit simplifies the creation of an event log by
removing the initial event and setting open time for all
event logs. This has the effect of potentially introducing
a gap between opened time for a log and the first peer
online event for peers with channels that exist at startup
if a peer takes time to reconnect. However, the cost of this
is less than the benefit of reducing the bug-prone custom
code path that was previously in place.
In this commit, the channelEventStore in the channel
fitness subsystem is changed to identify channels
by their outpoint rather than short channel id. This
change is made made becuase outpoints are the preferred
way to expose references over rpc, and easier to perform
queries within lnd.
Upgrade logging of channel uptime/lifespan query errors
to returning the error, with the exception of the case
where the channel is known to the store. This error is
logged, due to the potential for race conditions between
the channel event store being notified of a new open
channel and the rpc channel subscription creating a rpc
channel struct (which queries for uptime).
