In this commit, we change the flow of the rpc middleware registration
a bit. In order to allow a client to add rpc middleware interceptors in
a deterministic order, we now make the server send a "registration
complete" message to the client after compeleting the registration
process so that the client knows when it can go ahead and register the
next client.
Ensure the wallet has synced the blockchain before attempting to spend
funds.
Prior to this fix, I get the following error:
rpc error: code = Unknown desc = wallet couldn't fund PSBT: error
creating funding TX: insufficient funds available to construct
transaction
This commit removes the old multi shards test for `SendToRoute` as the
method doesn't support sending MPP. The original test passed due to a
flawed mocking method, where the mockers bypassed the public interfaces
to maintain their internal state, which caused a non-exsiting situation
that a temp error wouldn't fail the payment. A new unit test is added to
demonstrate the actual case.
This commit adds a new method `SendToRouteSkipTempErr` that skips
failing the payment unless a terminal error occurred. This is
accomplished by demoting the original `SendToRoute` to a private method
and creating two new methods on top of it to minimize code change.
With this commit we allow a replacement message to be sent by the
middleware for a request type as well as the response type. This allows
an incoming RPC request to be modified before it is forwarded to lnd.
Because of the way the gRPC Receive() method is designed, we need a way
to replace a proto message with the content of another one without
replacing the original instance itself (e.g. overwrite all values in the
existing struct instance).
If we don't flag the /v1/middleware call as request streaming, it can't
be used properly with REST WebSockets because the proxy would close the
connection after the first request message.
A new linter rule was added in the latest version that wants all fields
in a struct to be declared, even if the default value is used. Because
that would mean a large diff for us, we disable the rule for now.
This commit changes how we locate the next migration height by including
the scenario where `lnd@v0.15.0` is active. In the new version, we will
see a mixed of new and old logs under the same open channel bucket.
Hence, we need to alter how we locate the next un-migrated height.
