An often requested feature is to use the abandonchannel API in regular
builds and not only dev builds to get rid of stuck channels that had
their funding transaction invalidated.
The initial reason for putting the call behind the build flag was a
safety concern to make sure nobody uses this on active channels by
accident.
With this patch, we'll fail out earlier in the cycle in case of
some wonky parameters, and not leave zombie payments in the router
which currently are not cleaned up.
GetNodeInfo retrieves the policies for every edge the node belongs to.
When these policies are retrieved from the database, they're returned
in the following order: the first policy is the outgoing policy from the
node, and the second is the incoming policy to the node. This ordering
is not consistent with the ordering we have within our other RPCs like
GetChanInfo and DescribeGraph, where policies are sorted based on the
smaller public key of the nodes within an edge.
We fix this by maintaining the same order as our other RPCs.
The router has a lot of work to do for each block. So it might be
possible that it isn't yet up to date with the most recent block,
even if the wallet is. This can happen in environments with high CPU
load (such as parallel itests). Since the `synced_to_chain` flag in
the response of this call is used by many wallets (and also our
itests) to make sure everything's up to date, we add the router's
state to it. So the flag will only toggle to true once the router was
also able to catch up.
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.
In this commit, we add strict zombie pruning as a config level param.
This allow us to add the option for those that want a tighter graph, and
not change the default composition of the channel graph for most users
over night.
In addition, we expand the test case slightly by testing that the self
node won't be pruned, but also that if there's a node with only a single
known stale edge, then both variants will prune that edge.
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.

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.
This commit achieves what we have been building up to: running the
WalletUnlockerService and the LightningService on the same gRPC server
simultaneously!
To achieve this, we first create the RPC server in a "interface only"
way, only creating the struct and setting the dependencies we have
available before the wallet has been unlocked. After the wallet has been
unlocked and we have created all the subsystems we need, we add those to
the RPC server, and start the sub-servers.
This means that the WalletUnlockerService and the LightningService both
will be registered and available at all times on the gRPC server.
However, before the wallet has been unlocked, the LightningService
should not be used since the RPC server is not yet ready to handle the
calls. Similarly, after the wallet has been unlocked, the
WalletUnlockerService should not be used. This we will ensure in
following commits.
We don't have to define the external subserver config more than once, so
it is not needed to be defined for every listener. Instead we move it to
the ListenerConfig.
This adds a new package rpcperms which houses the InterceptorChain
struct. This is a central place where we'll craft interceptors to use
for the GRPC server, which includes macaroon enforcement.
This let us add the interceptor chain to the GRPC server before the
macaroon service is ready, allowing us to avoid tearing down the GRPC
server after the wallet has been unlocked.
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.
This commit uses the new coop-close-target-confs value as the default to
use for a nodes self initiated channel closures if the conf-target flag
for the channel closure is not set. The defaults for both these options
is 6 so this shouldnt change current behaviour.
