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.
Using AbandonChannel, a channel can be abandoned. This means
removing all state without any on-chain or off-chain action.
A close summary is the only thing that is stored in the db after
abandoning.
A specific close type Abandoned is added. Abandoned channels
can be retrieved via the ClosedChannels RPC.
In this commit, we extend the current SubscribeInvoice streaming RPC
call. We add two new values to the InvoiceSubscription message:
add_index and settle_index. These fields have also been added to the
current Invoice message. Each time a new invoice is added, the add index
will be incremented. Each time a new invoice is settled the settle index
will be incremented. The new field on the InvoiceSubscription message
allow callers to specify the last add index and the last settle index
they know of. With this new addition, callers will now be able to
reliably receive notifications for new received payments.
Care has been taken to ensure that these changes are backwards
compatible. If callers don't specify either of the new fields, then they
won't receive any notification backlog at all.
Fixes#862.
- Extend SendRequest and QueryRoutesRequest protos
- newRoute function takes fee limit and cuts off routes that exceed it
- queryRoutes, payInvoice and sendPayment commands take the feeLimit inputs and pass them down to newRoute
- When no feeLimit is included, don't enforce any feeLimits at all (by setting feeLimit to maxValue)
In this commit, we add a `private` field to the `AddInvoice` RPC's
request to denote whether the invoice being created should include
routing hints for private channels to assist the payer in reaching the
destination.
Changes in gRPC `channelbalance` service response message
of adding `pending_open_balance` parameter with sum of
channels open pending balances denominated in satoshis
In this commit, we add a new method to the RPC service:
ForwardingHistory. This method will allow callers to query for the
completed payment circuits in a particular time slice, skip a series of
events, and also paginate within a time slice.
In this commit, we revamp the WalletUnlocker service to now have a
two-stage init process.
The first (optional) is for the user instantiating a new lnd instance to
call the GenSeed method with an optional aezeed passphrase. The response
to this will be a freshly generated aezeed mnemonic along with the
original enciphered seed.
The second step will be the actual wallet initaliztion. By separating
this step from seed generation, UI's will be able to ensure that the
user has written down the seed, before proceeding and committing the
seed to the internal wallet. The new method InitWallet accepts a wallet
passphrase, the aezeed mnemonic, and the optional passphrase.
This commit adds wallet_best_block_timestamp to the gRPC interface.
This is done in order to allow clients to calculate progress while
lnd syncs to the blockchain. wallet_best_block_timestamp is exposed
via the GetInfo() rpc call. Additionally, IsSynced() returns the
WalletBestBlockTimestamp as the second value in the tuple
that is returned, providing additional detail when querying about the
status of the sync. The BtcWallet interface has also been updated
accordingly.
This commit was created to support the issue to
[Add progress bar for chain sync] (lightninglabs/lightning-app#10) in
lightning-app
Fixes#481.
Prior to this commit, payments stored in the channel DB only kept a
record of the payment hash. This is a problem as the preimage is what
serves as proof of payment and a user should be able to look up this
value in the future (not just immediately after payment).
Instead of storing both the payment hash and the preimage, we store the
preimage only since the hash can be derrived from this using a SHA256.
In the RPC listpayments command, we now give the preimage in addition to
the payment hash.
This commit changes the listinvoices and lookupinvoice endpoints to
avoid collisions when making requests.
We can still retrieve a list of pending invoices with `listinvoices` by
appending the parameter `pending_only=true` to the request URL.
This commit renames the UpdateFee RPC call together
with associated types to UpdateChannelPolicy. In addition
to fees, now also timelock delta can be specified using
this call.
In this commit, we remove the blocks_till_open from
PendingChannelsResponse as in its current state, the values that are
assigned to this field don’t accurately reflect the naming. This has
caused a good bit of confusion amongst users lately. As a result, we’re
temporarily removing this field until we have proper incremental
notifications within the chain notifier.
In this commit we rename the lnrpc.PendingChannelRequest and
lnrpc.PendingChannelResponse to
lnrpc.PendingChannelsRequest/lnrpc.PendingChannelsResponse. We do this
as we strive to ensure that the naming scheme across the RPC interface
is consistent.
In this commit, we expose the new fee control features to the relevant
commands on the command line. This will allow users to have a greater
degree of control of the fees they pay when: sending coins on chain,
opening a channel, or closing a channel.
In this commit, we modify the OpenChannel, CloseChannel, SendCoins, and
SendMany RPC’s to be able to allow users to manually specify their
fees. Users can either specify a target number of confirmations, or a
target value for manual sat/byte.
This commit adds the service WalletUnlocker, which is to be used
for creating a wallet password at first time startup, and unlocking
the wallet. The service exposes the RPC methods CreateWallet and
UnlockWallet.
This commit adds fields that are supported by the BOLT-11 invoice
format to the Invoice and PayReq protos. These fields are
timestamp, expiry, fallback address, description and
description hash.
This commit removes the revocation_delay field from the HTLC proto as
we no longer need this field since the switch to 2-layer HTLC’s. The
2-layer HTLC construction no longer has the CSV delay directly in the
HTLC script itself.
This commit adds to new RPC’s to the Lightning service: UpdateFees and
FeeReport. Additionally, we also update to the latest version of protc,
golang protobuf, and the gRPC gateway.
This commit removes the num_confs parameter within the
OpenChannelRequest struct as it’s no longer applicable with the new
funding workflow. In the new funding workflow, it’s the responder that
decides how many confirmations are required.
In order to not close the payment stream on payment error the additional
field have been added in payment response. Now error from stream Recv()
function means that something has happend inside the client and we unable
to process any payment farther, and error inside the payment response
means, that something wrong has happend with payment itself.
This commit allows users to sign messages with their node's private key
with the SignMessage interface. The signatures are zbase32 encoded for
human readability/paste-ability. Others users can verify that a message
was signed by another node in their channel database with the
VerifyMessage interface.
This commit adds simple non-blocking stop command to lncli, with an
appropriate proto update and implementation within the rpcserver. When
invoked the interrupt handler routine in signal.go with begin the graceful
shutdown of lnd.
This commit adds some additional fields to the PendingChannels RPC s.t
users will be able to use the RPC to gain a complete view w.r.t where
all the funds within the daemon are, and how soon they can be
retrieved.
The following information is now returned:
* all channels pending open
* all channels pending cooperative close
* all channels pending force close
This commit modifies address handling in the NodeAnnouncement struct,
switching from net.TCPAddr to []net.Addr. This enables more flexible
address handling with multiple types and multiple addresses for each
node. This commit addresses the first part of issue #131 .
This commit converts the previous QueryRoute command to a new command:
QueryRoutes. This command is identical to QueryRoute other than the
fact that it’s able to return multiple routes rather than a single
route.
This commit adds a new field to the ListChannels RPC command which
indicates if the peer is currently online or not. This is useful as
UI’s will be able to use this information to communicate the
availability of each channel to an end user.
This commit modifies the protobuf file and most of the auto-generated
files to be generated by protoc version v3.0.2. Additionally, this
fixes a minor cosmetic regression within the `lncli` command line tool
which caused the JSON responses to be rendered in `camelCase` rather
than `snake_case`. We fix this by specifying the `json_name` for each
relevant RPC response.
Because we want to persist the state of the channel once the funding
transaction has been broadcast rather than once it has been fully
opened, we need to report the funding transaction ID to the UI or tests
when the transaction is pending, rather than after it has been
confirmed.
Previously, during the channel funding process, peers sent wire
messages using peer.queueMsg. By switching to server.sendToPeer, the
fundingManager is more resilient to network connection issues or system
restarts during the funding process. With server.sendToPeer, if a peer
gets disconnected, the daemon can attempt to reconnect and continue the
process using the peer’s public key ID.
This commit modifies the ListInvoice RPC to also return the encoded
payment request in the response. With this change it’ll be possible to
always obtain the encoded payment for any invoice, rather than only
being able to obtain it directly after the creation of an invoice.
This commit removes the remote_funding field from the OpenChannel
message as dual funding channels aren’t yet supported at the wire level
within the spec (although the daemon is able to handle them properly).
In place we now add the ‘push_sat’ field which allows the initiator to
push over a certain amount to the responder as part of the initial
state.
This commit adds a number of new RPC’s which allow users to query data
that’s now exposed as part of the new routing package: DescribeGraph,
GetChanInfo, GetNodeInfo, QueryRoute, GetNetworkInfo, and SetAlias.
As a result the former ShowRoutingTable command has been removed as the
underlying graph representation has changed.
This commit expands the data returned by the current GetCurrentHeight
to also return the current best block hash, expanding the method into
GetBestBlock. Additionally, the current best BlockHash is also now
displayed within the GetInfo RPC call.
This commit adds synchronous version of the RPC’s to send payments over
channels and open new channels. The previous async versions of these
RPC calls have been removed from the REST interface.
Additionally for these two RPC calls any field which accepted byte
slices now also accept a variant of the field which is a hex-encoded
string.
The OpenChannelSync RPC is intended to be used along with either the
ListChannels or PendingChannels RPC to poll for a channels existence or
non-existence as a signal that the channel is finally open.
This commit modifies a few of the RPC call which previously took a
lightning_id as their paramter to instead take a compressed public key
field. With this change must of the code within the daemon can be
simplified as we only use public keys everywhere throuhgout the daemon.

This commit adds a REST interface to the existing gRPC server by
employing a simple http proxy auto-generated from the existing protobuf
files. Currently full-support for any streaming RPC’s are currently
untested. In addition to auto-generating a REST proxy server, a
swagger.json is also generated which allows for gRPC-like native
objects with higher-level clients, and also for auto-generated
documentation.
Due to limitations with accepting raw byte strings as parameters, some
RPC’s have been modified to take both raw-bytes and string arguments.
Additionally a new RPC has been added ‘NewWitnessAddress’ since the
proxy doesn’t currently support enum-based arguments.
Currently the proxy server is embedded within the daemon as an active
HTTP server, however we may want to package the proxy server as a
separate binary in the future. Similarly, we may want to add additional
configuration information which controls the optional inclusion of the
REST proxy.
Atm, just like the current gRPC interface, the REST API is fully
unauthenticated. Before moving to an initial alpha release after making
the necessary changes to meet the spec drafted in Milan, authentication
of the RPC interfaces will be addressed.
This commit extracts the channel information that was previously
returned within the ListPeers command to a new RPC command:
ListChannels. Additionally, any pending HTLC’s within the open channel
are also displayed.
This commit adds a new RPC command: `channelbalance` which returns the
sum of all available channel capacity across all open channels. The
total balance is currently returned in units of `satoshis`. Additionally
the `networkHarness` has been modified slightly to allow specifying the
additional "extra" command line parameters when creating the initial
seed nodes. Minor refactoring within the integration tests has been
undertaken in order to increase code re-use across tests.
Closes#29.

This commit modifies the prior protos to make the open/close channel
RPC commands return the “union” status update rather than a concrete
item of that union directly. With this change, RPC clients can now
receive status updates of the current state of the opening or closing
channel.
This commit integrates BitFury's current routing functionality into lnd. The
primary ochestration point for the routing sub-system in the routingMgr. The
routingMgr manages all persistent and volatile state related to routing within
the network.
Newly opened channels, either when the initiator or responder are inserted into
the routing table once the channel is fully open. Once new links are inserted
the routingMgr can then perform path selection in order to locate an "optimal"
path to a target destination.
