The grpc-gateway library that is used to transform REST calls into gRPC
uses a different method for reading a request body stream depending on
whether the RPC is a request-streaming one or not. We can't really find
out what kind of RPC the user is calling at runtime, so we add a new
parameter to the proxy that lists all request-streaming RPC calls.
In any case the client _has_ to send one request message initially to
kick off the request processing. Normally this can just be an empty
message. This can lead to problems if that empty message is not
expected by the gRPC server. But for the currently existing two
client-streaming RPCs this will only trigger a warning
(HTLC interceptor) or be ignored (channel acceptor).
Since we want to support AMP payment using a different unique payment
identifier (AMP payments don't go to one specific hash), we change the
nomenclature to be Identifier instead of PaymentHash.
We'd never decrement the number of pending backups upon a watchtower
accepting one, making it confusing for users to determine whether their
backups have actually been accepted. Along the way, we also rename
NumTasksReceived to NumTasksPending to better reflect its purpose.
This commit adds a []*lnrpc.NodeAddress typed node_addresses field
on the NodeUpdate message of SubscribeChannelGraph to mirror the
addresses field in the LightningNode message of DescribeGraph.
Fixes https://github.com/lightningnetwork/lnd/issues/4084
This commit deprecates/replaces the old field `sat_per_byte` with
`sat_per_vbyte`. While the old field suggests sat per byte, it’s
actually using sat per virtual byte. We use the Hidden param to hide all
the deprecated flags. These flags won't show up in help menu onwards,
while stay valid that can be passed from cli. Thus bash scripts
referencing these fields won't be broken.
In order to be able to register the subservers with the root grpc server
before we have all dependencies available, we wrap them in an
GrpcHandler struct. This struct will initially hold an empty reference
to the subservers, which allows us to register with the GRPC server, and
later populate and create the subserver instance.
This allows to use FowardingHistory rpc method to receive the data exactly
as it's stored in lnd and to synchronize incrementally the history to an
external database.
