Due to some of the previous commits, we no longer have persistent
connections to peers whom we have no open channels with. It might be the
case that this is triggered throughout any of the tests, so we'll ensure
that the Alice and Bob harnesses are connected before running each test.
This change makes the test more sensitive to bugs than a route
with nodes that all enforce the same fee policy.
In addition to that, the fee has been increased to a level
at which potential problems with improper fee calculation
become detectable (and not disappear in rounding).
With the recent bug fixes in the peer connection, it's no longer the
case that just disconnecting a certain peer causes it to no longer
connect to the other. As a result, we now shutdown Alice to ensure no
reconnection occurs. We'll then later restart alice when we restart
dave.
This commit adds the helper method shutdownAndAssert, and makes us shut
down nodes created temporarily during the test cases using defers
instead of at the end of the test. This makes it easier to remember to
shut them down, as it is done right after they are started.
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.
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.
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
counterparty tries to settle an HTLC with the wrong preimage, the
channel is failed and force closed.
In this commit, we rewrite the node announcement integration test to no
longer depend on a sleep interval. Instead, we use graph topology
updates in order to be notified exactly when we receive the node
announcement.
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.
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.
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.
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.
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.
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
changes to the ChannelArbitrator, where it will only act on commitments
that has been confirmed. Main changes involving when to look for
transactions in the mempool and in blocks, and using the new RPC for
getting channels in the "waiting close" phase when they are waiting for
the commitment to confirm.
