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.
We also test that legacy keysend payments are promoted to AMP payments
on the receiver-sdie by asserting basic properties of the fields
returned via the rpc.
In this commit, we raise the default value for the `MaxParts` field from
1 to 16. This change was motivated by the fact that many users either
forget, or don't even know this field is there in the first place. A
value of 16 was chosen rather arbitraliy (other than power of 2). In
the future, we should tune this value based on the expected number of
payment attempts for a given payment amount.
This allows users to see progress whenever the docker image is
[re]built, and (esp on non-linux hosts) track the size of the build
context being uploaded. Currently no output is displayed, so it's hard
to attribute the source of latency, e.g. network latency, building
layers, a large work directory, etc.
Now that we have a base docker image that has all our RPC compilation
dependencies installed, we can also run the mobile RPC compilation
there. This removes the need to install falafel and goimports on the
local machine.
This commit aims to make it easier for developers to compile our
protobuf definitions. They now only need to have docker installed
instead of a whole set of binaries and libraries all pinned to very
specific versions.
In this commit, we extend the `BuildRoute` method and RPC on the router
sub-server to accept a raw payment address which will be included as
part of an MPP payload for the finla hop. This change actually also
allows users to craft their own MPP paths using BuildRoute+SendToRoute.
Our primary goal however, was to fix some broken itests since we now
require the payAddr to be present for ALL payments other than key send
payments.
