Since a ChannelPoint's funding txid can now be get/set as raw bytes or
a string, we first need to check what type it's currently set to before
accessing it.
In this commit, we fix an existing flake on Travis related to the new
set of on-chain HTLC tests. In this timing flake, Bob would broadcast
his sweeping transaction, but *mid block mining*. As a result, the
output would never be properly swept, needing an additional block to be
mined. We’ll now wait for both Bob’s sweeping transaction, and Carol’s
sweep transaction to be confirmed before we attempt our assertions.
In this commit, we fix an existing bug in the implementation of the
resolution of the htlcOutgoingContestResolver. Before this commit, we
would _always_ watch the claim outpoint. However, if this is on the
remote party’s commitment transaction, then we would end up watching
the wrong output. We’ll now properly detect this by modifying which
output we watch, based on if we have a second level transaction or not.
In this commit, we add 6 new integration tests to test the various
actions that may need to be performed when either side goes on-chain to
fully resolve HTLC’s. Many of the tests are mirrors of each other as
they test sweeping/resolving HTLC’s from both commitment transactions.
In this commit, we modify the testChannelForceClosure integration test
to account for the fact that now the HTLCs are only sent to the nursery
once they’ve fully timed out. Additionally, we now send Carol HTLCs
that she doesn’t know the preimage to, so she doesn’t attempt to sweep
them before we can actually time them out.
This commit adds a new integration test, that checks that
policy/fee updates get propagated properly in the network,
such that the other nodes learn about the changes.
This commit extracts the launching of a goroutine subscribing
to and forwarding graph topology notifications into its own
utility method, such that it can be used in other tests as
well.
This commit adds a line of text including a test case's
name to Alice's and Bob's logfiles during integration
tests, making it easier to seek for the place in the log
where the specific tests start.
This commit adds a new test, that in a small network
of 4 nodes, tests that a private channel can be used
for routing payments by the endpoints of the channel,
while the existence of the channel is not known to
the rest of the network.
In this commit we rename the lnrpc.PendingChannelRequest and
lnrpc.PendingChannelResponse to
lnrpc.PendingChannelsRequest/lnrpc.PendingChannelsResponse. We do this
as we strive to ensure that the naming scheme across the RPC interface
is consistent.
This commit adds a small cancellation check to the
invoice subscription integration test. Calls to
Fatalf were observed on travis after the test had
ended stemming from the subscriber's goroutine,
which could happen if the subscription is late.
It also extends the timeout on the test from 5 to
10 seconds.
There is a sleep after channels are opened to ensure the channel is
removed from the set of pending reservations. We can avoid this sleep
and get better guarantees of the channel being opened by deleting the
reservation just before updating channel state to active instead of
after.
This helps catch issues in the RPC tests faster by putting a timeout
on all SendPayment requests. Otherwise, if a payment stalled, the test
would run until the test suite timeout, 10 minutes. Also simplifies
some code with a helper function and using SendPaymentSync where
possible.
If an lnd node encounters a fatal process errors, we now log the error
asynchronously, instead of calling Fatalf on the test instance. This
is because calling Fatalf in a separate goroutine does not actually
end the test immediately as expected, but rather just kills the
goroutine. This ensures that we see server errors on all nodes before
the test process exits.
In this commit, we increase the initial amount sent in the multi-hop
error integration test. We must do this now as the Bandwidth() function
now takes into account the total fee paid within the commitment
transaction. This caused an earlier send to fail instead of the once
following send.
To fix this, we simply send less in the initial test case.
This commit removes the testChannelReestablishment integration test as
it is currently incomplete. In order to properly test this, we require
some infrastructure that allows us to kill the connection at will once
a message is sent across the wire.
In this commit BOLT№2 retranmission logic for the channel link have
been added. Now if channel link have been initialised with the
'SyncState' field than it will send the lnwire.ChannelReestablish
message and will be waiting for receiving the same message from remote
side. Exchange of this message allow both sides understand which
updates they should exchange with each other in order sync their
states.
