This commit adds a new config method `QueryIncomingCircuit` that can be
used to query the payment's incoming circuit for giving its outgoing
circuit key.
`IncubateOutputs` never takes more than one HTLC, so we change the
params to be optional, which helps with the following commit where we
pass the deadline height when incubating outgoing HTLCs.
This commit adds a new group config `BudgetConfig` to allow users
specifying their own preference when sweeping outputs. And a new config
option `NoDeadlineConfTarget` is added in case the user wants to use a
different "lazy" conf target.
This commit makes the `ClusterInputs` directly returning the `InputSet`
so the sweeper doesn't know about the existence of `Cluster` interface.
This way we can have a deeper interface as the sweeper only needs to
interact with `Aggregator` only to get the final input sets, leaving the
implementation details being managed by `SimpleAggregator` and future
aggregators.
This commit changes how a new input sweep request is handled - now we
will query the mempool and see if it's already been spent. If so, we'll
update its state as we may need to RBF this input.
This commit refactors the grouping logic into a new interface
`UtxoAggregator`, which makes it easier to write tests and opens
possibility for future customized clustering strategies.
The old clustering logic is kept as and moved into `SimpleAggregator`.
This commit refactors the sweeper so the method `feeRateForPreference`
is now moved to `FeePreference`, which makes our following refactor
easier to handle.
Add an option to disable route blinding, failing back any HTLC with
a blinding point set when we haven't got the feature enabled.
Note that this commit only handles the case where we're chosen as the
relaying node (where the blinding point is in update_add_htlc), we'll
add handling for the introduction node case once we get to handling of
blinded payloads).
This commit moves the constants LndInternalLockID and
DefaultLockDuration from the walletrpc package to the chanfunding
package, moves DefaultReservationTimeout from lncfg to chanfunding,
and also updates the lncli package with the new location.
Since we have two other examples of XArbitrator, we rename
BreachArbiter to BreachArbitrator to keep things consistent.
The aim is to reduce the amount of lore you need to know to
intuit where things are or what they do.
This commit moves over the last two methods, `RegisterChannel` and
`BackupState` from the `Client` to the `Manager` interface. With this
change, we no longer need to pass around the individual clients around
and now only need to pass the manager around.
To do this change, all the goroutines that handle channel closes,
closable sessions needed to be moved to the Manager and so a large part
of this commit is just moving this code from the TowerClient to the
Manager.
In this commit, the `Stop` and `Start` methods are removed from the
`Client` interface and instead added to the new `Manager`. Callers now
only need to call the Manager to start or stop the clients instead of
needing to call stop/start on each individual client.
Introduce a wtclient `Manager` which handles tower clients. It indexes
clients by the policy used. The policy field is thus removed from the
`Config` struct which configures the Manager and is instead added to a
new `towerClientCfg` which configures a specific client managed by the
manager. For now, only the `NewClient` method is added to the Manager.
It can be used to construct a new `TowerClient`. The Manager currently
does notthing with the clients added to it.
In preparation for the next commit which will remove the
`*LightningNode` from the `ChannelEdgePolicy` struct,
`FetchLightningNode` is modified to take in an optional transaction so
that it can be utilised in places where a transaction exists.
To prepare for the `kvdb.Backend` member of `ChannelEdgeInfo` being
removed, the `FetchOtherNode` method is moved from the `ChannelEdgeInfo`
to the `ChannelGraph` struct.
Having a `ForEachChannel` method on the `LightningNode` struct itself
results in a `kvdb.Backend` object needing to be stored within the
LightningNode struct. In this commit, this method is replaced with a
`ForEachNodeChannel` method on the `ChannelGraph` struct will perform
the same function without needing the db pointer to be stored within the
LightningNode. This change, the LightningNode struct more closely
represents the schema on disk.
The existing `ForEachNodeChannel` method on `ChannelGraph` is renamed to
`ForEachNodeDirectedChannel`. It performs a slightly different function
since it's call-back operates on Cached policies.
This commit removes the `Litecoin`, `LtcMode` and `LitecoindMode`
members from the main LND `Config` struct. Since only the bitcoin
blockchain is now supported, this commit also deprecates the
`cfg.Bitcoin.Active` config option.
In this commit, we update the Sig type to support ECDSA and schnorr
signatures. We need to do this as the HTLC signatures will become
schnorr sigs for taproot channels. The current spec draft opts to
overload this field since both the sigs are actually 64 bytes in length.
The only consideration with this move is that callers need to "coerce" a
sig to the proper type if they need schnorr signatures.
Because we now send the correct initial forwarding policy to Brontide,
the correct initial values are inserted into the link and we no longer
need to update the link in a later step.
Since the actual wallet backends might be different between the wallet
DB and the actual channel state DB, we pass in the correct struct to the
funding manager.
This commit adds a new itest case to check the race condition found in
issue #7401. In order to control the funding manager's state, a new dev
config for the funding manager is introduced to specify a duration we
should hold before processing remote node's channel_ready message.
A new development config, `DevConfig` is introduced in `lncfg` and will
only have effect if built with flag `integration`. This can also be
extended for future integration tests if more dev-only flags are needed.
This commit does a few things:
- First, it gives the sessionQueue access to the TowerClient task
pipeline so that it can replay backup tasks onto the pipeline on Stop.
- Given that the above is done, the ForceQuit functionality of the
sessionQueue and TowerClient can be removed.
- The bug demonstrated in a prior commit is now fixed due to the above
changes.
In this commit, a `DefaultWtClientCfg` function is added which
populates some default values for the `WtClient` struct. This is then
used to populate the wtclient defaults in the main LND config struct.
