In this commit, we start to expose some of the new external funding
functionality over the RPC interface.
First, we add a new `funding_shim` field to the regular `OpenChannel`
method. This can be used by a caller to express that certain parameters
of the funding flow have already been negotiated outside the protocol,
and should be used instead. For example, a shim can be provided to use a
particular key for the commitment key (ideally cold) rather than use one
this is generated by the wallet as normal, or signal that signing will
be carried out in an interactive manner (PSBT based).
Next, we add a brand new method: `FundingStateStep`. FundingStateStep is
an advanced funding related call that allows the caller to either
execute some preparatory steps for a funding workflow, or manually
progress a funding workflow. The primary way a funding flow is
identified is via its pending channel ID. As an example, this method can
be used to specify that we're expecting a funding flow for a particular
pending channel ID, for which we need to use specific parameters.
Alternatively, this can be used to interactively drive PSBT signing for
funding for partially complete funding transactions.
The new transition methods (funding state machine modifiers) in this
commit allow a party to register a funding intent that should be used
for a specified incoming pending channel ID. The "responder" to the
external channel flow should use this to prep lnd to be able to handle
the channel flow properly.
This commits builds on top of PR #3694 to further clarify invoice
state by defining pending invoices as the ones which are not
settled or canceled. Automatic cancellation of expired invoices
makes this possbile. While this change only directly affects
ChannelDB, users of the listinvoices RPC will receive actual
pending invoices when pending_only flag is set.
In this commit, we add `msats` to the return value of `DecodePayReq` to
ensure we always show full value information as we're moving to do
generally for all RPC calls that deal with off-chain amounts.
With this PR we deprecate fields that have been specifically added to
to work around a bug in the gRPC/REST gateway that didn't allow bytes
fields to be encoded in REST requests.
That bug has now been fixed so the fields are no longer required.
To make it more clear how bytes fields have to be used in REST,
comments have been added to all those fields.
This commit add mpp_total_amt_msat and mpp_payment_addr to the Hop
message. Doing so enables users submitting mpp payments via rpc to
set these parameters for the destination. In addition, it will allow us
to display these fields in rpc responses.
This commit adds the total observed lifetime of a channel and the
totaluptime of its remote peer to the lnrpc channel struct. These
fields are marked as experimential because they are subject to
change.
This sets the `jstype` option to `JS_STRING` for all `chan_id` fields
in the proto rpc definition. `chan_id` is a 64 bit integer, which is
not natively supported by javascript's floating-point `number` with
only 52 bit precision. Nevertheless, by default protobuf will use the
`number` type for 64 bit integer fields in javascript, which can cause
loss of precision problems with `chan_id`. Explicitly setting the type
for javascript as a string will prevent these issues, and should not
interfere with its use as an identifier.
With the introduction of the max CLTV limit parameter, nodes are able to
reject HTLCs that exceed it. This should also be applied to path
finding, otherwise HTLCs crafted by the same node that exceed it never
left the switch. This wasn't a big deal since the previous max CLTV
limit was ~5000 blocks. Once it was lowered to 1008, the issue became
more apparent. Therefore, all of our path finding attempts now have a
restriction of said limit in in order to properly carry out HTLCs to the
network.
In order to prevent future unforeseen issues, we are temporarily
disabling the ability to send custom tlv records to the receiver of a
payment. Currently the receiver does not process or expose these
additional fields via rpc or internally, so they are being disabled
until the end-to-end flow is finished and fully validated.
In this commit, we add a new field to the Hop proto to allow callers to
be able to specify TLV records for the SendToRoute call, and also to be
able to display TLV records that were used during regular path finding.
We also update SendPayment to support dest TLV records.
Previously mission control tracked failures on a per node, per channel basis.
This commit changes this to tracking on the level of directed node pairs. The goal
of moving to this coarser-grained level is to reduce the number of required
payment attempts without compromising payment reliability.
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 upgrades the protobuf version. Compared to the previous
v1.2.0 it generates smaller diffs in generated code. This change was
introduced in:
fffb0f7828
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.
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.
