Not all errors that occur when serving client requests in the gRPC
server are logged. As a result, at times, we can be lacking critic
information that can be used to debug issues that pop up. With this PR,
we create a basic streaming+unary interceptor that will log all errors
that occur when servicing calls.
The current format looks something like this in the logs when an error
occurs:
```
[ERR] RPCS: [/lnrpc.Lightning/SendCoins]: decoded address is of unknown format
```
lnrpc/rpc.proto: updates RoutingPolicy last_update number
rpcserver: adding LastUpdate field to marshalDbEdge
This commit adds a LastUpdate field to each RoutingPolicy, it will show
the time each RoutingPolicy was updated.
lnrpc: regenerating proto files
In this commit two fields were added to the Channl RPC result in both
open and pending states.
The fields: local_chan_reserve, remote_chan_reserve represents the
reservation the nodes are rquired to keep in both sides of the channel.
This is usefull when calculating the "real" inbound and outbound
liquidity in an accurate way.
This commit fixes a but where restarting LND at the same process causes
It to fail.
The problem resides in the fact that an array of permissions is
initialized as a package variable and when creating the
RPCServer all subserver permissions are appended while checking for
duplicates.
On subsequent restart this array is left over from the previous run and
being populated again with the same permissions causing a duplicate
error.
The solution is simple, just to extract out the initial permissions to
a separate function and call it from the context is is needed.
Earlier versions of ListPayments only included completed payments. We
return to this behavior by ignore all other payments if the nonSucceeded
boolean is not set in the request.
Start the Prometheus exporter in rpcserver.go if monitoring is enabled through the
build tag. Also allow users to specify what address they want the Prometheus
exporter to be listening on.
This commit moves the default timeout out of router and thereby fixes a
bug that caused SendToRoute to not return the actual error, but a
timeout result instead. SendToRoute only tries a single route, so a
timeout should never happen.
This commit makes the router use the ControlTower to drive the payment
life cycle state machine, to keep track of active payments across
restarts. This lets the router resume payments on startup, such that
their final results can be handled and stored when ready.
Now that the success resolver preimage field is always populated by the
incoming contest resolver, preimage lookups earlier in the
process (channel and channel arbitrator) can mostly be removed.
This commit restructures the creation of various tls related object. It
also fixes a bug where wildcard IP addresses where only instantiated for
the main RPC server and not the WalletUnlocker service.
In this commit, we modify the `closeObserver` to fast path the DLP
dispatch case if we detect that the channel has been restored. We do
this as otherwise, we may inadvertently enter one of the other cases
erroneously, causing us to now properly look up their dlp commitment
point.
lnd_test: adding address validation for send coins
The commit adds a test that checks that when a user calls sendcoins, the
receiving address is validated according to the current network. If the
address is not compatible with the current network, it will return an
error to the user.
rpcserver: adding a check for compatible network in SendCoins
This commit adds a check in SendCoins that checks whether the receiving
address is compatible with the current network.
Fixes#2677.
This is a better alternative than retrieving it from the graph as it's
possible that the channel is pruned from it doing to not having any
updates within the past two weeks.
This commit moves the query routes backend logic from the main
rpc server into the sub server. It is another step towards splitting up
the main rpc server code.
In addition to this, a unit test is added to verify rpc parameter
parsing.
Currently public keys are represented either as a 33-byte array (Vertex) or as a
btcec.PublicKey struct. The latter isn't useable as index into maps and
cannot be used easily in compares. Therefore the 33-byte array
representation is used predominantly throughout the code base.
This commit converts the argument types of source and target nodes for
path finding to Vertex. Path finding executes no crypto operations and
using Vertex simplifies the code.
Additionally, it prepares for the path finding source parameter to be
exposed over rpc in a follow up commit without requiring conversion back
and forth between Vertex and btcec.PublicKey.
This commit allows the execution of QueryRoutes to be controlled using
lists of black-listed edges and nodes. Any path returned will not pass
through the edges and/or nodes on the list.
In this commit, we rename the new `MaxHtlc` field to `MaxHtlcMsat`. We
do this in order to adhere to the new practice to suffix each amount
related field with their proper unit.
A recent change in this area of the codebase refactored some code to
make way for the deprecation of the streaming multi-route `SendToRoute`
method. Along the way, it removed the parsing of the `PaymentHashString`
field for the sync `SendToRouteSync` which is meant to be used via the
REST interface. In this commit, we fix this by populating _both_
`PaymentHash` and `PaymentHashString`. This is OK, as
`extractPaymentIntent` will check both values to extract the hex-encoded
payment hash if it's specified.
`createRPCChannel` is used by the `listchannels` RPC call and will be
used by `subscribechannels` as well.
`createRPCClosedChannel` is used by the `closedchannels` RPC call and
will also be used by `subscribechannels`.
This is used by the `listchannels` RPC call and will be used by
`subscribechannels` as well. Its purpose is to mitigate code duplication
between the two RPC calls.
