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.
Replace logCommitTick as a way to deal with revocation window exhaustion
by retrying to update the commit tx when the remote revocation is
received.
The rationale is that the revocation window always opens up because of a
revoke message that is received from the other party. It is therefore
not necessary to set a timer for this. The reception of the revoke
message is the trigger to send a new commit sig if necessary.
Instead of tracking local updates in a separate link variable, query
this state from the channel itself.
This commit also fixes the issue where the commit tx was not updated
anymore after a failed first attempt because the revocation window was
closed. Also those pending updates will be taken into account when the
remote party revokes.
Previously the channel method FullySynced was used to decide whether to
send a new commit sig message. However, it could happen that FullySynced
was false, but that we didn't owe a commitment signature. Instead we
were waiting on the other party to send us a signature. If that
happened, we'd send out an empty commit sig. This commit modifies the
condition that triggers a new commit sig and fixes this deviation from
the spec.
To facilitate the logging, this commit adds a new OweCommitment method.
For the logging, we only need to consider the remote perspective. In a
later commit, we'll also start using the local perspective to support
the decision to send another signature.
In this commit, we refactor the testSingleHopSendToRoute test to support
table driven tests for various endpoints and payment types. Currently
only the main rpcserver's SendToRoute is tested, so we also add
support the SendToRouteSync and the routerrpc's SendToRoute.
The tests are also modified to have each endpoint perform a single-hop,
single-shot MPP payment. This asserts that the Hop messages are being
properly unmarshalled and that setting correctly yields a successful
payment. At the momemnt the receiver does not actually verify or use the
MPP fields presented in the onion, though this test will be expanded
later as those pieces are assembled.
This commit parses mpp_total_amt_msat and mpp_payment_addr from the
SendToRoute rpc and populates an MPP record on the internal hop
reprsentation. When the router goes to encode the onion packet, these
fields will be serialized for the destination. We also populate the mpp
fields when marshalling routes in rpc responses.
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.
These encoders can be composed to create composite types without
incurring additional allocations that would be required to pass the
truncated types through the generic interface.
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.
In this commit, we convert the existing `channeldb.ChannelType` type
into a _bit field_. This doesn't require us to change the current
serialization or interpretation or the type as it is, since all the
current defined values us a distinct bit. This PR lays the ground work
for any future changes that may introduce new channel types (like anchor
outputs), and also any changes that may modify the existing invariants
around channels (if we're the initiator, we always have the funding
transaction).
This commit adds a new signal to the autopilot agent, meant to signal
when any of the available heuristics has gotten an update.
We currently use this to trigger a new channel opening after the
external scores have been updated.
