This change makes sure that all macaroons are stored in the same
folder. This makes it possible to use the lntest package in external
projects that use loop's lndclient library which currently assumes
that the admin macaroon and subserver macaroons are in the same sub
folder of lnd's data directory.
Integration tests in external projects might not have the same folder
structure as lnd does. Therefore we want to allow the path to the
lnd itest binary to be configurable.
When using the lntest package for itests in external projects, it
is necessary to access a harness node's configuration, for example
to get its data directory on disk. This commit exports that
configuration.
This changes the HarnessNode structure to hold onto the client grpc
connection made during startup so that it can close it during shutdown.
This is needed because the grpc.Dial function spins a new goroutine that
attempts to maintain an open connection to the target endpoint and
without calling Close() in the connection while shutting down the node
we leak this goroutine to the rest of the tests.
This changes TCP port selection in integration tests from being
sequential, based on the node ID to being sequential but tested before
assigment.
This should reduce the number of flaky tests that fail due to the port
already being used by another process in the CI server.
Previously every payment had its own local mission control state which
was in effect only for that payment. In this commit most of the local
state is removed and payments all tap into the global mission control
probability estimator.
Furthermore the decay time of pruned edges and nodes is extended, so
that observations about the network can better benefit future payment
processes.
Last, the probability function is transformed from a binary output to a
gradual curve, allowing for a better trade off between candidate routes.
This commit gives the current chainbackend the ability to connect and
disconnect the chain backend at will. We do this to let the chain
backend initiate the connection to the miner, not the other way around.
This is a preparation for using Neutrino as a backend, as it only allows
making outbound connections.
We must also move the setup of the chainbackend to after to miner, to
know the address to connect to.
This race was possible due to us making a subscription request before
the ChannelRouter has started. We address it by creating a dummy
subscription before proceeding to the real one to ensure we can do so
successfully. We use a dummy one in order to not consume an update from
the real one. This addresses the common "timed out waiting for opened
channel" flake within the integration test suite since the subscription
was never properly created, so we'd never be notified of when new graph
updates were received.
In this commit, we convert the Unlock method to accept the
`lnrpc.UnlockWalletRequest`. This makes things a bit more generic as we
no longer need to continue to add params to the method each time a new
field is added to the Unlock method.
We need to distinguish an lnd build for the purpose of integration
testing from a regular dev build. This makes it possible to adapt
parameters to let integration tests run faster (for example:
sweeper batch window).
