This commit swaps out golang/protobuf/jsonpb for a custom variant that
by default prints byte slices as hex, which is more useful for our
setting. Some existing wrapper structs are removed as they can now be
printed directly with the new jsonpb.
!!! NOTE !!!
This commit introduces a breaking change to lncli listinvoices since
payment hashes and preimages will now be printed in hex instead of
base64.
This commit updates the BOLT11 test vectors to use the updated versions
from the spec (with TLV bit set). This also pointed out that the
ordering was inconsistent with the spec, in that the payment secret
should be serialized before the feature vector.
This PR fixes an issue that happens when adding a new channel edge
between two nodes in a memChannelGraph. Originally a channel edge held a
node value which made the graph different when iterating from the two
endpoints of an edge. This is simply fixed by holding pointers instead.
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.
This commit fixes a potential bug in our test harness, by ensuring that
the constructed node policies are configured _after_ sorting. Currently
the node pubkeys are sorted, but additional parameters (max htlc,
disabled, etc) are applied using the unsorted policies.
Most of the constructors used today use the symmetric channel
constructor, so this shouldn't cause an issue with the majority of our
tests. We recently introduced an asymmetric channel constructor for
which this could have been an issue, however, no known issues were
discovered.
Lastly, we remove the direction from the configuration altogether, and
derive it purely from the final sorting of the pubkeys.
This commit constructs a helper closure assertAmountSent that can be
reused by other functions. The closure returns an error so that it can
be used with wait.NoError or the new wait.InvariantNoError. The latter
is added since the predicate could otherwise pass immediately for the
sphinx_replay_persistence tests, but change shortly after. It also
rounds out the wait package so that we offer all combinations of
predicate and no-error style waits.
We move up the check for TLV support, since we will later use it to
determine if we can use dependent features, e.g. TLV records and payment
addresses.
This commit creates a wrapper struct, grouping all parameters that
influence the final hop during route construction. This is a preliminary
step for passing in the receiver's invoice feature bits, which will be
used to select an appropriate payment or payload type.
In this commit, we overwrite the final hop's features with either the
destination features or those loaded from the graph fallback. This
ensures that the same features used in pathfinding will be provided to
route construction.
In an earlier commit, we validated the final hop's transitive feature
dependencies, so we also add validation to non-final nodes.
This commit adds an optional PaymentAddr field to the RestrictParams, so
that we can verify the final hop can support it before doing an
expensive round of pathfindig.
In this commit, we fix a bug that prevents us from sending custom
records to nodes that aren't in the graph. Previously we would simply
fail if we were unable to retrieve the node's features.
To remedy, we add the option of supplying the destination's feature bits
into path finding. If present, we will use them directly without
consulting the graph, resolving the original issue. Instead, we will
only consult the graph as a fallback, which will still fail if the node
doesn't exist since the TLV features won't be populated in the empty
feature vector.
Furthermore, this also permits us to provide "virtual features" into the
pathfinding logic, where we make assumptions about what the receiver
supports even if the feature vector isn't actually taken from an
invoice. This can useful in cases like keysend, where we don't have an
invoice, but we can still attempt the payment if we assume the receiver
supports TLV.
This commit allows custom node features to be populated in specific test
instances. For consistency, we auto-populate an empty feature vector for
nodes that have nil feature vectors before writing them to the database.
Previously we would return nil features when we didn't have a node
announcement or a given node. With this change, we can always assume the
feature vector is populated during pathfinding.
This changes the HarnessNode structure to hold onto the client grpc
connection made during startup so that it can close it during shutdown.
This is needed because the grpc.Dial function spins a new goroutine that
attempts to maintain an open connection to the target endpoint and
without calling Close() in the connection while shutting down the node
we leak this goroutine to the rest of the tests.
Adds a global Authenticate method that can be used to get the
atuhentication options needed to call the grpc server.
Currently meant only for used with the mobile bindings, so we use the
admin macaroon.
