This RPC exposes the recently added BumpFee functionality to the
UtxoSweeper in order to allow users of the RPC to manually bump fees of
low fee inputs/transactions.
This commit exposes the three main parameters that influence mission
control and path finding to the user as command line or config file
flags. It allows for fine-tuning for optimal results.
Previously every payment had its own local mission control state which
was in effect only for that payment. In this commit most of the local
state is removed and payments all tap into the global mission control
probability estimator.
Furthermore the decay time of pruned edges and nodes is extended, so
that observations about the network can better benefit future payment
processes.
Last, the probability function is transformed from a binary output to a
gradual curve, allowing for a better trade off between candidate routes.
This PR replaces the previously used edge and node ignore lists in path
finding by a probability based system. It modifies path finding so that
it not only compares routes on fee and time lock, but also takes route
success probability into account.
Allowing routes to be compared based on success probability is achieved
by introducing a 'virtual' cost of a payment attempt and using that to
translate probability into another cost factor.
This commit upgrades the protobuf version. Compared to the previous
v1.2.0 it generates smaller diffs in generated code. This change was
introduced in:

This fixes a bug where the RHashStr field on the PaymentHash request for
SubscribeSingleInvoice was being ignored. This replaces the PaymentHash
message for the SubscribeSingleInvoice request with a new message called
SubscribeSingleInvoiceRequest that contains only the RHash field.
This commit modifies the invoice registry to handle invoices for which
the preimage is not known yet (hodl invoices). In that case, the
resolution channel passed in from links and resolvers is stored until we
either learn the preimage or want to cancel the htlc.
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.
Now that QueryRoutes gained the ability to route from any source node
and takes in edge and node black lists, all pieces are in place to have
users implemented their own k-shortests path algorithm. Or any other algorithm
they might wish to use and currently can't.
This commit marks the num_routes field as deprecated as a preparation
for removing k-shortest for lnd.
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 add two new address types to `NewAddressRequest`.
These address types will allow the caller to retrieve the last _unused_
address, rather than always rotating to the next address in the
keychain.
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.
In this commit, we implement the full RouterServer as specified by the
newly added sub-service as defined in router.proto. This new sub-server
has its own macaroon state (but overlapping permissions which can be
combined with the current admin.macaroon), and gives users a simplified
interface for a gRPC service that is able to simply send payment. Much
of the error reporting atm, is a place holder, and a follow up commit
will put up the infrastructure for a proper set of errors.
This commit is a step to split the lnwallet package. It puts the Input
interface and implementations in a separate package along with all their
dependencies from lnwallet.
Update is necessary to get protoc to generate files in the right
directory when using modules outside the gopath. The old version of this
dependency did not support paths=source_relative.
This commit also fixes a build error in lnd_test.go because of a
slight difference in generated code.
This commit adds a new service lnrpc/autopilot, that is to be used to
communicate with the running autopilot. Currently a RPC for getting the
status of the agent is included, as well as enabling/disabling at
runtime.
Returns a brief json summary of each utxo found by calling
ListUnspentWitness in the wallet. The two arguments are the
minimum and maximum number of conrfirmations (0=include
unconfirmed)
In this commit, we implement the newly defiend WalletKitServer gRPC
service. We use the same template w.r.t build tags as the existing
signrpc service.
In this commit, we add a new sub-RPC server to the existing set of gRPC
servers. This new sub-RPC server is the WalletKit. It's a utility
toolkit that contains method which allow clients to perform common
interactions with a wallet such as getting a new address, or sending a
transaction. It also includes some supplementary actions such as fee
estimation.
One thing to note in the RPC file is that we _import_ the existing
signer.proto file in order to get at some existing proto definitions
which are useful in our use case.
In this commit, we add the ComputeInputScript which will allow callers
to obtain witnesses for all outputs under control of the wallet. This
allows external scripting of things like coin join, etc.
In this commit, we add the glue infrastructure to make the sub RPC
server system work properly. Our high level goal is the following: using
only the lnrpc package (with no visibility into the sub RPC servers),
the RPC server is able to find, create, run, and manage the entire set
of present and future sub RPC servers. In order to achieve this, we use
the reflect package and build tags heavily to permit a loosely coupled
configuration parsing system for the sub RPC servers.
We start with a new `subRpcServerConfigs` struct which is _always_
present. This struct has its own group, and will house a series of
sub-configs, one for each sub RPC server. Each sub-config is actually
gated behind a build flag, and can be used to allow users on the command
line or in the config to specify arguments related to the sub-server. If
the config isn't present, then we don't attempt to parse it at all, if
it is, then that means the RPC server has been registered, and we should
parse the contents of its config.
The `subRpcServerConfigs` struct has two main methods:
`PopulateDependancies` and `FetchConfig`. The `PopulateDependancies` is
used to dynamically locate and set the config fields for each new
sub-server. As the config may not actually have any fields (if the build
flag is off), we use the reflect pacakge to determine if things are
compiled in or not, then if so, we dynamically set each of the config
parameters. The `PopulateDependancies` method implements the
`lnrpc.SubServerConfigDispatcher` interface. Our goal is to allow sub
servers to look up their actual config in this main config struct. We
achieve this by using reflect to look up the target field _as if it were
a key in a map_. If the field is found, then we check if it has any
actual attributes (it won't if the build flag is off), if it is, then we
return it as we expect it to be populated already.
In this commit, we create a lnrpc.SubServerDriver for signrpc. Note that
this file will only have its init() method executed if the proper build
flag is on. As a result, only if the build flag is set, will the RPC
server be registered, and visible at the packge lnrpc level for the root
server to manipulate.
In this commit, we add a full implementation of the new SignerServer sub
RPC service within the main root RPC service. This service is able to
fully manage its macaroons, and service any connected clients. Atm, this
service only has a single method: SignOutputRaw which mimics the
existing lnwallet.Signer interface within lnd itself. As the API's are
so similar, it will be possible for a client to directly use the
lnwallet.Signer interface, and have a proxy that sends the request over
RPC, and translates the proto layer on both sides. To the client, it
doesn't know that it's using a remote, or local RPC.
In this commit, we add the scafolding for the future sub-server RPC
system. The idea is that each sub server will implement this particular
interface. From there on, a "root" RPC server is able to query this
registry, and dynamically create each sub-sever instance without
knowing the details of each sub-server.
In the init() method of the pacakge of a sub-server, the sub-server is
to call: RegisterSubServer to claim its namespace. Afterwards, the root
RPC server can use the RegisteredSubServers() method to obtain a slice
of ALL regsitered sub-servers. Once this list is obtained, it can use
the New() method of the SubServerDriver struct to create a new
sub-server instance.
Each sub-server needs to be able to locate it's primary config using the
SubServerConfigDispatcher interface. This can be a map of maps, or a
regular config structr. The main requirement is that the sub-server be
able to find a config under the same name that it registered with. This
string of abstractions will allow the main RPC server to find, create,
and run each sub-server without knowing the details of its configuration
or its role.
In this commit, we add a new proto generation script to match the one in
the main lnrpc package. This script differs, as we don't need to
generate the REST proxy stuff (for now).
In this commit, we introduce a new sub-package within the greater RPC
package. This new sub-package will house a new set of sub-RPC servers
to expose experimental features behind build flags for upstream
consumers. In this commit, we add the first config for the service,
which will simply expose the lnwallet.Signer interface over RPC.
In the default file, we have what the config will be if the build tag
(signerrpc) is off. In this case, the config parser won't detect any
times, and if specified will error out. In the active file, we have the
true config that the server will use. With this new set up, we'll
exploit these build flags heavily in order to create a generalized
framework for adding additional sub RPC servers.
In this commit, we modify the AbandonChannel REST endpoint to avoid
conflicting with the CloseChannel's. Otherwise, if a debug build of lnd
is being used, there's no way of closing channels through the REST API
as it's been overwritten by AbandonChannel.
By passing a pubkey into SendToRoute, it becomes unnecessary for lnd to
query the channel graph to retrieve the hop pubkey. This allows routes
over private channels that are not present in the graph.
In this commit, we address a slight regression in the defaults provided
by the OpenChannel RPC with regards to spending unconfirmed outputs to
fund funding transactions. We now add a new boolean parameter to
OpenChannelRequest: SpendUnconfirmed. If set, we'll use this to
indicate to the server that the funding transaction of the channel to be
created can spend the wallet's unconfirmed outputs to fund it. This
addition is needed because otherwise, if the caller doesn't specify a
MinConfs parameter to the request, then a default of 0 will be used,
which is not ideal.
In this commit, we remove the unnecessary NewWitnessAddress RPC. We do
this as, at the moment, we only expose the wallet to generate witness
addresses. Now that the RPC has been removed, its REST endpoint has been
assigned to the NewAddress RPC, which should be the de facto way of
having the wallet generate any type of supported address.
Fixes#1986.
