This commit introduces the Signature interface which will be used by our
witness construction methods instead of passing in raw byte slices. This
will be used later to inject various kinds of mock signatures, e.g.
73-byte signatures for simulating worst-case witness weight.
This commit fixes the inconsistency between the payment state as
reported by routerrpc.SendPayment/routerrpc.TrackPayment and the main
rpc ListPayments call.
In addition to that, payment state changes are now sent out for every
state change. This opens the door to user interfaces giving more
feedback to the user about the payment process. This is especially
interesting for multi-part payments.
This commit removes the overflowQueue from the link. We do so in order
to promote better UX for senders, so that HTLCs are failed faster when
the commitment is full. This gives the sender the opportunity to try
another, more open path, rather than perceive the HTLC as being stuck.
At the same time, we remove the total number of active goroutines in lnd
by a factor of N where N is the number of active channels.
This commit is preparation for the test added in the subsequent commit.
We modify makeHoldPayment to return any failures direectly when trying
to add an HTLC to the switch. This lets us know that the HTLC was indeed
sent without failure when the method returns.
A following commits will move/modify callsites of AckPacket, Start, and
Stop, none of which use the return value and ultimately cause the linter
to complain. However, none of these in-memory operations can fail so we
just remove the returned errors altogether.
Changes the grpc proto file, generates the protobuf, and
enables a queried way to retrieve payments in the rpc, where
backward compatibility is enforced by returning all payments
in the database by default. Adds a payment index field to
the returned payments of the rpc call.
Adds a PaymentsQuery struct, which contains parameters to restrict the
response of QueryPayments, returning a PaymentsQuerySlice with the
payments query result. The behavior of this api is the same as
the QueryInvoices one.
This is mainly motivated by a now fixed bug in the wallet in which
change addresses could at times be created outside of the default key
scopes. Recovery only used to be performed on the default key scopes, so
ideally this test case would've caught the bug earlier.
Update the PendingChannel message from a bool to an enum to
differentiate between the case where the remote party initiated the
channel and we have no record of the channel initiator. The previous
field has not been included in a release of lnd, so we can replace the
field directly.
Move enum out of CloseSummary struct for more general use. This does
not change the encoding of the enum, and will only cause compile time
errors for existing clients. This enum has not been included in a
release yet, so we can make this move without much disruption.
This commit adds an additional santity check that rejects zero-value
HTLCs, preventing them from being added to the channel state even if the
channel config's minhtlc value is zero.
In #4130, OpenChannel was changed to assert that the wallet is fully
synced before allowing a channel open. This introduced flakes on travis,
which are resolved here by using a wait predicate when calling
OpenChannel.
Note there is one existing call that was not converted, because it is
interested in the returned error. This call does not have a wait
predicate surrounding it, but this shouldn't cause a flake because other
channels are opened earlier in the test that will have already waited
for the wallet to sync up.
