In this commit, a new `--db.no-rev-log-amt-data` flag is added. The
config option is passed though to everywhere that it will be used. Note
that it is still a no-op in this commit. An upcoming commit will make
use of the flag.
Define a MigrationConfig interface that should be used to pass the
config of an optional migration function. An implementation of this
interface is added for migration30 (the only current optional
migration).
As is, we'll never get any add/remove features because the flag is
set as an int 64 slice but accessed as an int slice (which has no
value, and the cli doesn't fail if the flag doesn't exist).
The active probability estimator can be switched dynamically using the
`Set/GetMissionControl` API, maintaining backward compatibility. The
lncli commands `setmccfg` and `getmccfg` are updated around this
functionality. Note that deprecated configuration parameters were
removed from the commands.
We use a more general `Estimator` interface for probability estimation
in missioncontrol.
The estimator is created outside of `NewMissionControl`, passed in as a
`MissionControlConfig` field, to facilitate usage of externally supplied
estimators.
Implements a new probability estimator based on a probability theory
framework.
The computed probability consists of:
* the direct channel probability, which is estimated based on a
depleted liquidity distribution model, formulas and broader concept derived
after Pickhardt et al. https://arxiv.org/abs/2103.08576
* an extension of the probability model to incorporate knowledge decay
after time for previous successes and failures
* a mixed node probability taking into account successes/failures on other
channels of the node (similar to the apriori approach)
The storage of final htlc resolutions is a safety-critical feature. By
exposing it through the GetInfo call, connected applications can
ensure that the feature is turned on and avoid relying on the assumption
that lnd was configured correctly.
The grpc stream.Recv() will decode an ForwardHtlcInterceptResponse
without an IncomingCircuit, which will leave that pointer nil,
causing a nil pointer dereferece when components of in.IncomingCircuitKey
are used in the resolveFromClient() function.
This commit checks for the nil pointer and returns an error before
the rest of the parsing.
We introduce a probability `Estimator` interface which is implemented by
the current apriori probability estimator. A second implementation, the
bimodal probability estimator follows.
With this commit, we can define an address type for default/imported
accounts in FundPsbt using '—change_type' flag. The value for this
flag can only be 'p2tr' at the moment. If not specified, we will use
P2WKH addresses for change outputs. Custom accounts don’t support
this flag as they have a unique scope.
By default, P2TR addresses are used for changes. However, some users
might encounter some problems with this change. We add the possibility
to define a custom address type in FundPsbt for default/imported accounts
(only P2TR for now). If no address type is specified for these accounts,
we will use P2WKH by default.
The SendOutputs method isn't used very often in our code so the missing
Taproot sighash type wasn't detected before.
Also, a P2TR input will never have a sigScript, so we can explicitly set
that parameter to nil instead of relying on it being nil anyway.
There is a one byte difference between the sigScript and the
witnessScript in case of a np2wkh input. The remote signer actually
needs the witness script and not the sig script to produce a valid
signature.
Fixes an issue where re-using a sign descriptor in a loop carried over
signing information from one call to the next, which caused the remote
signing issue.
* we rename the current probability estimator to be the "apriori"
probability estimator to distinguish from a different implementation
later
* the AprioriEstimator is exported to later be able to type switch
* getLocalPairProbability -> LocalPairProbabiltiy (later part of an
exported interface)
* getPairProbability -> getPairProbabiltiy (later part of an exported
interface)
Since the cert pair is written with a subsequent call to
cert.WriteCertPair we can safely remove the two file paths from the
argument list of cert.GenCertPair.
This fixes a unit test flake that occurred sometimes if the temporary
directory was attempted to be deleted but the wallet or macaroon DB
hasn't been closed yet.
