e4e8b86137 tests: add integration tests for send to route
This commit add 3 integration tests for send-to-route RPC call.
One test ensures that single-hop payments are processed. Another test
checks that payments through a multi-hop route are processed. Lastly,
there is a test to check error propagation while sending payments via fake
predefined route.

Revert "test: account for block race by mining additional block in remote htlc force close test"
Before the previous commit, we assumed the HTLC's timeout transaction
would be the only transaction in the mempool. In reality, after mining
some blocks for the HTLC to expire and waiting for the timeout
transaction to arrive in the mempool, at times we would instead detect
the funding output's sweeping transaction and proceed the test with this
assumption, leading to the case where we would have to mine extra blocks
to include the HTLC sweeping transaction. This has been resolved in the
previous commit, so this fix is no longer needed.

This reverts commit e54f1ea4dbe59b2e53a94774995ae1711746c2f8.

test: detect funding output sweep tx after force close
In this commit, we address an existing flake that would be triggered
when testing HTLC timeouts. After force closing a channel and generating
enough blocks to expire an HTLC, we would wait for a transaction to
arrive in the mempool and assumed it was the timeout transaction.
Instead, we'd detect the funding output sweep transaction and attempt to
proceed with the test with the incorrect assumption of the timeout
transaction being broadcast.

This commit adds an integration test that checks that in case a channel

lnd_test: fix update channel policy flake
In this commit, we address a timeout issue on our Travis builds within
the update channel policy integration test. Before asserting the policy
for the channel between Alice and Bob, we need to make sure we receive
the updates responsible for modifying this policy first. At times, the
update wasn't received in time before checking the policy, which led to
us checking the old policy. We fix this by explicitly making sure we
wait for the updates first.

lnd_test: fix flake from routing hints for inactive channel
This commit attempts to fix a flake we have seen, where a routing hints
for an inactive channel was unexpectedly added to the invoice. This
happened because of a race between shutting down the endpoint of this
channel (Eve) and creating the invoice. This commit fixes this by moving
the call to AddInvoice with corresponding route hint check inside a
WaitPredicate.

test: fix revocation integration test flake
In this commit, we fix an existing flake within the set of revocation
integration tests. Right after Bob's restart, we attempt to force close
the channel. However, it may be the case that the chain arbitrator
hasn't yet been created. As a result, the request to force close the
channel will fail. We easily fix this by wrapping the force close
attempt in a WaitPredicate.

test: account for block race by mining additional block in remote htlc force close test
This commit is similar to a recent commit which attempts to account for
internal block races by mining a second block if the initial assertion
for HTLC state fails. This can happen again if by the time that the
sweeping transaction is broadcast, it doesn't make it into the next
block mine.

test: attempt to account for internal block race in htlc force close test
In this commit, we modify the
testMultHopRemoteForceCloseOnChainHtlcTimeout test slightly to attempt
to account for a block race between the arrival of a message betwen the
contract resolver and the utxo nursery. If this message arrives "late"
(relative to the speed with which we mine blocks in test), then it'll be
detected as such by the utxo nursery. However, since we attempt to mine
a precise number of blocks, if this happens, then we'll never actually
mine that extra block to trigger a broadcast of the sweep transaction.

lnd_test: remove racy block generation
This commit removes the mining of a block within the integration tests,
that would lead to a flake during runs. The reason was that the sweeoing
transaction was actually broadcast already at this point, and this block
was mined with the assumption that it wasn't. However, test would pass
more often than not because the UTXO nursery would be working on
graduating new heights, whcih is a bit slow, so in most cases the block
would be mined before it had broadcast the sweeping transaction.

By removing this block we ensure that the sweeping transaction will be
found for sure in the waitForTxInMempool call below.

This commit modifies the integration tests to work with the recent

test: in testUpdateChannelPolicy wait for Alice to learn of all channels
In this commit, we fix an existing flake in the integration tests. If it
was the case that Alice didn't yet know of all the channels, then the
payment attempt below would fail at times, depending on other timing
factors in the test. We fix this flake by waiting for Alice to learn of
all channels before we proceed to the actual testing logic.

test: extend closeChannelAndAssert to also check that channel is no longer pending close
In this commit, we extend the closeChannelAndAssert testing utility
function to ensure that the channel is no longer marked as "pending
close" in the database. With this change, we hop to catch a recently
reported issue wherein users report that a co-op close channel has been
fully confirmed, yet it still pops up in the `pendingchannels` command.

test: update testUpdateChannelPolicy to ensure Bob's link uses the proper policies
In this commit, we update the testUpdateChannelPolicy to exercise the
recent set of changes within the switch. If one applies this test to a
fresh branch (without those new changes) it should fail. This is due to
the fact that before, Bob would attempt to apply the constraints of the
incoming link (which we updated) instead of the outgoing link. With the
recent set of changes, the test now properly passes.

In this commit, we fix an existing flake on Travis related to the new

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.

78f8ddef72 lnd: Remove some sleeps in integration tests.
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.

c501da3a95 lnd: Context timeouts on SendPayment RPC request in tests.
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.

643c23f978 lnd: Improve error handling for node failures in integration tests.
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.

test: decrease amount sent in multi-hop error integration test
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.

test: remove testChannelReestablishment integration test
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.

d70ffe93e4 htlcswitch+channel: add channel states synchronization
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.

lnd_test: add channel graph reorg test
This commit adds a test for an lnd instance experiecing a reorg,
making sure a channel that is in the channel graph (using the
describegraph rpc call) will no longer be after the funding tx
gets reorged out.

test: make assertNumOpenChannelsPending poll every 200ms
In this commit, we modify the assertNumOpenChannelsPending to poll
every 200ms rather than just a single attempt. The goal of this commit
is to reduce the number of flakes on travis caused by slow instances.
