In this commit, the channelEventStore in the channel
fitness subsystem is changed to identify channels
by their outpoint rather than short channel id. This
change is made made becuase outpoints are the preferred
way to expose references over rpc, and easier to perform
queries within lnd.
Upgrade logging of channel uptime/lifespan query errors
to returning the error, with the exception of the case
where the channel is known to the store. This error is
logged, due to the potential for race conditions between
the channel event store being notified of a new open
channel and the rpc channel subscription creating a rpc
channel struct (which queries for uptime).
In the process, we also move the feature serialization into the
invoicesrpc package, so that it can be shared between the invoicesrpc
and main rpcserver.
This commit prepares for more manipulation of custom records. A list of
tlv.Record types is more difficult to use than the more basic
map[uint64][]byte.
Furthermore fields and variables are renamed to make them more
consistent.
This commit is adapted from @Bluetegu's original
pull request #1462.
This commit reads an optional address to pay funds out to
from a user iniitiated close channel address. If the channel
already has a shutdown script set, the request will fail if
an address is provided. Otherwise, the cooperative close will
pay out to the address provided.
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.
In this commit, we update the `AbandonChannel` method to also remove the
state from the countract court as well as the channel graph. Abandoning
a channel is now a three step process: remove from the open channel
state, remove from the graph, remove from the contract court. Between
any step it's possible that the users restarts the process all over
again. As a result, each of the steps below are intended to be
idempotent.
We also update the integration test to assert that no channel is found
in the graph any longer. Before this commit, this test would fail as the
channel was still found in the graph, which can cause other issues for
an operational daemon.
Fixes#3716.
The channel arbitrator no longer passes the direct commitment output to
the nursery for incubation. Instead the resolver itself will await the
csv lock if any.
The reason to change this now is to prevent having to deal with the
(legacy) nursery code for a planned anchor outputs related change to the
commit sweep resolver (also csv lock to_remote).
It is no problem if there are any lingering incubating outputs at the
time of upgrade. This just means that the output will be offered twice
to the sweeper and this doesn't hurt.
In this commit, we create a new chainfee package, that houses all fee
related functionality used within the codebase. The creation of this new
package furthers our long-term goal of extracting functionality from the
bloated `lnwallet` package into new distinct packages. Additionally,
this new packages resolves a class of import cycle that could arise if a
new package that was imported by something in `lnwallet` wanted to use
the existing fee related functions in the prior `lnwallet` package.
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.
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.
Fixes https://github.com/lightningnetwork/lnd/issues/3357. When
start_time isn't specified, its default value is 0. This meant when
users explicitly specified a start_time of 0, we would incorrectly set
start_time to 24 hours in the past. Now, n0 means n0.
The policy update logic that resided part in the gossiper and
part in the rpc server is extracted into its own object.
This prepares for additional validation logic to be added for policy
updates that would otherwise make the gossiper heavier.
It is also a small first step towards separation of our own channel data
from the rest of the graph.
In this commit, we fix a bug where if a user updates a forwarding policy to be
zero, the update will be applied to the policy correctly on-disk, but not
in-memory.
We solve this issue by having the gossiper return the list of on-disk updated
policies and passing these policies to the switch, so the switch can assume
that zero-valued fields are intentional and not just uninitialized.
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.
Debug invoices are rarely used nowadays, but keep asking for maintenance
every time refactoring in primarily the invoice registry occurs. We have
passed the cost/benefit tipping point, so therefore the debug invoice
concept is removed in this commit.
Previously the debughtlc flag also controlled whether hodl masks were
active. It is safe to remove that additional condition because the hodl
masks are still guarded by the dev build tag.
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.
