Fixes a subtle bug where the outer scope predErr was hidden when the
return value of findForceClosedChannel was stored in a newly
defined variable with the same name.
Start anchor sweep attempts immediately after the commitment transaction
has been published. This makes the anchor known to the sweeper and
allows the user to bump the fee on it to get their commitment
transaction confirmed in case the fee committed too is insufficient for
timely confirmation.
In this commit, we extend the current SCB recovery tests to also cover
the new anchor commitment type. We only add a single test that covers
the most common case to avoid needing to tests all cases for all
commitment types which is being done in a follow up PR.
The synchronous call to get all channel backups also include
channels that are pending at the moment of the call. A previous
commit added pending channels to the file based backup as well. So
this is the last backup method that needs to be adjusted to also
contain unconfirmed channels.
Update channel updates and subscription itest to check that close
initiator is appropriately set for cooperative and force closes for the
local and remote party.
This commit adds PendingOpenChannel to SubscribeChannelEvents stream in
the gRPC API.
This is useful for keeping track of channel openings that Autopilot does.
It can also be used for the non-initator side of a channel opening to keep
track of channel openings.
To ensure lnd is able to pick up an on-chain preimage properly after a
restart, we suspend Alice and check that the payment is listed correctly
as succeeded after a restart.
This change makes sure that all macaroons are stored in the same
folder. This makes it possible to use the lntest package in external
projects that use loop's lndclient library which currently assumes
that the admin macaroon and subserver macaroons are in the same sub
folder of lnd's data directory.
Integration tests in external projects might not have the same folder
structure as lnd does. Therefore we want to allow the path to the
lnd itest binary to be configurable.
When using the lntest package for itests in external projects, it
is necessary to access a harness node's configuration, for example
to get its data directory on disk. This commit exports that
configuration.
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.
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.
Since CSV locked outputs specifies the first block where they are
allowed to be included, they can actually be added one block earlier
into the mempool.
This led to a flake, where the sweep tx was already in the mempool at
the time we mined the last block, causing the next mempool check to
fail.
This commit adds an itest assertion to check that a coop closed
channel's status is properly refelcted in list channels. We also fix a
race condition that prevented the rpc from being externally consistent
by marking the close sooner in the pipeline.
This changes TCP port selection in integration tests from being
sequential, based on the node ID to being sequential but tested before
assigment.
This should reduce the number of flaky tests that fail due to the port
already being used by another process in the CI server.
Refresh channel memory state whenever the short channel id is refreshed.
This is to make the in-memory channel consistent with the disk data.
Fixes#3765.
This fixes an issue that would lead to a flake during intergration
tests. Carol would start up with a outdated state and attempt to force
close the channel. At the same time she would connect to Dave,
triggering the dataloss protection. Dave would respond by force closing
the channel, and Dave transaction would in some cases have a higher fee,
resulting Carol's tx being replaced.
We fix this by suspending Dave until Carol's close tx is mined.
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.
This commit beings the process of deprecating unsafe-disconnect. Many
moons ago this was disallowed to prevent concurency bugs surrounding
reconnect. Despite the name, it has been safe to enable this feature for
well over a year, as several PRs have been merged that addressed the
possible issues that existed when the feature was added.
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.
We might hit a connection refused error in cases where the peer connects
to us exactly as we try to connect to it. We retry the connection within
a wait predicat, as it should be the case that the other peer
establishes the connection, and the two peers actually connects.
We add a wait predicate to make sure the node's on-chain balance is
restored before continuing the restore test case.
This is needed since the DLP test scenario includes several restarts of
the node, and if the node isn't done scanning for on-chain balance
before the restart happens, it would be unlocked without a recovery
window, causing funds to be left undiscovered.
Since the ErrorCodes are not part of the spec, they cannot be read by
other implementations.
Instead of only sending the error code we therefore send the complete
error message. This will have the same effect at the client, as it will
just get the full error instead of the code indicating which error it
is. It will also be compatible with other impls.
Note that the GRPC error codes will change, since we don't set them
anymore.
This changes the defer function in the test for channel backups to
correctly close over the 'dave' variable.
Without this closure, the shutdownAndAssert call would attempt to
shutdown the original (non-restored) dave instead of the most recently
created (restored) dave, causing a leak of a node during tests.
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.
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.
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.
