The test assumed that transactions would be broadcast and confirmed at
incorrect heights. Due to timing issues, it was possible for the test to
still succeed, resulting in a flake.
The test assumes that Bob will sweep a pending outgoing HTLC and commit
output back to their wallet. This commit ensures that these operations
are done when expected, i.e.:
1. Bob force closes the channel due to the HTLC timing out.
2. Once the channel is confirmed, Bob broadcasts their HTLC timeout
transaction.
3. Bob broadcasts their commit output sweep transaction once its CSV
expires.
4. Bob broadcasts their second layer sweep transaction for the timed out
HTLC once its CSV expires.
In this commit, we lower the mempool spend check timeout to be twice as
long as the trickle interval of the miner node, which will greatly
improve the execution time of this specific test. We're able to do this
now since we can specify custom trickle intervals for our test
harnesses.
Alice and Dave don't need to be connected in order to receive the node
announcement as we assume that she can receive it from Bob because they
are connected at the beginning of every test.
This commit modifies paymentLifecycle so that it not only feeds
failures into mission control, but successes as well.
This allows for more accurate probability estimates. Previously,
the success probability for a successful pair and a pair with
no history was equal. There was no force that pushed towards
previously successful routes.
In this commit, we force Dave to use the legacy onion payload for the
multi-hop test to ensure that we're able to properly mix the old and new
formats, and have all nodes properly decode+forward the HTLC.
In this commit, we add a new build tag protected sub-config for legacy
protocol features. The goal of this addition is to be able to default to
new feature within lnd, but expose hooks at the config level to allow
integration tests to force the old behavior to ensure that we're able to
support both the old+new versions.
In this commit, we update the `HopIterator` to gain awareness of the new
TLV hop payload. The default `HopIterator` will now hide the details of
the TLV from the caller, and return the same `ForwardingInfo` struct in
a uniform manner. We also add a new method: `ExtraOnionBlob` to allow
the caller to obtain the raw EOB (the serialized TLV stream) to pass
around.
Within the link, we'll now pass the EOB information into the invoice
registry. This allows the registry to parse out any additional
information from the EOB that it needs to settle the payment, such as a
preimage shard in the AMP case.
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.
In this commit, we extend the path finding to be able to recognize when
a node needs the new TLV format, or the legacy format based on the
feature bits they expose. We also extend the `LightningPayment` struct
to allow the caller to specify an arbitrary set of TLV records which can
be used for a number of use-cases including various variants of
spontaneous payments.
In this commit, we extend the Hop struct to carry an arbitrary set of
TLV values, and add a new field that allows us to distinguish between
the modern and legacy TLV payload.
We add a new `PackPayload` method that will be used to encode the
combined required routing TLV fields along any set of TLV fields that
were specified as part of path finding.
Finally, the `ToSphinxPath` has been extended to be able to recognize if
a hop needs the modern, or legacy payload.
In this commit, we add two new method so the `Record` struct: Type() and
Encode(). These are useful when a caller is handling a record and may
not know its underlying type and may need to encode a record in
isolation.
