This fixeslightninglabs/loop#437 by adding all accounts that are used
in liquidity products such as Loop or Pool. Since both of these products
use key families below 255, we can get by with that number.
The alternative to creating way too many accounts (which increases the
default wallet size by ~250kB) would be to hard code the exact accounts
used by Loop (99) and Pool (210). But that sounds like a bad idea given
that there could always be more accounts being added to those (or other)
products. By making sure the first 255 accounts exist, we have a lot
more flexibility in those products for choosing key families.
With the remote signing instance now not needing to know anything about
addresses or current derivation indices, we don't need to forward any
such calls to that instance and can simplify the RPCKeyRing
considerably.
This commit adds a new component, harness miner, to the itest. This
newly added component is responsible for checking the mempool and blocks
for the itest.
This commit adds a new struct RPCClients to better handle rpc clients.
A private field, rpc, is added to HarnessNode to prevent direct access
to its clients. Inside RPCClients, all clients are exported in case a
test case need access to a specific client.
This adds an integration test that makes sure channel can be funded from
empty wallet using PSBT if the funding transaction contains an output
belonging to the wallet, satisfying the reserve.
This commit removes the context as a param needed when calling methods
of HarnessNode. This change moves the context management inside
HarnessNode, aside from saving us a few lines, it makes the context
creation/timeout less error-prone.
This commit adds a running context to HarnessNode which replaces all the
background context used and also serves as a way to signal quit when the
test is shutting down.
This commit adds a unique request ID that is the same for each gRPC
request and response intercept message or each request/response message
of a gRPC stream.
This commit adds a new unique intercept message ID that is different for
each message sent to an RPC middleware. This will allow us to re-purpose
the existing request ID field into its original intention, which was to
have a unique ID for a full gRPC request/response pair or gRPC stream as
a whole.
Unfortunately, we can't use the graph cache directly here as it doesn't
include all the information we need, since it only includes the minimal
amount of information needed for path finding.
Instead, we use a simple mutex guarded cache that evicts itself after a
certain interval. The default is set small enough that most users
shouldn't really notice. We also provide a way to disable the cache, and
also disable the cache in the itests.

It looks like in some cases (apparently mostly on Windows) a previous
sub test sometimes leaves some unconfirmed balance in the wallet. That
balance is confirmed in the next test when new coins are sent to the
wallet.
It looks like in some cases a channel is still being closed while we
already try to create a sweep output. In that case the pending closed
channel is still counted as anchor channel and a reserve output is
created. To make sure that doesn't happen, we make sure there are no
pending or open channels of any kind around before we create the sweep
transaction.
The testing framework uses runtime.Goexit() when a test fails which
still allows the defer calls to execute. That's why we should use defer
to close the done channel to allow all goroutines to exit properly.
We update several of our integration tests that exercise different
scenarios with regards to the broadcast of a channel commitment
transaction with HTLCs in-flight to use the new commitment type for
channel leases. We do this to ensure we have complete coverage of said
channel commitment type. This required changing several assumptions
throughout the tests based on when we should expect sweeps to happen.
