In this commit, we remove the sleep timeouts used within the channel
force closure integration test. This is needed because the recent changes
within the ChainNotifier require a longer timeout due to making a
database transaction on every new block to update the confirm/spend
hints of transactions. Rather than increasing the timeouts, we simply
remove them to ensure this isn't an issue down the road.
This commit changes the test testSendUpdateDisableChannel to use Dave to
listen for channel updates, as was originally intended.
Since a ChannelUpdate won't propagate in the network if the channel is
already closed (if the closing transaction has been mined), we change
the closing procedure to initiate the closing process, wait for the
ChannelUpdates, then finally mining the closing transaction. This avoids
a propagation race between the mined block and the ChannelUpdate.
This commit adds the integration test testDataLossProtection, that
ensures that when a node loses state, the channel counterparty will
force close the channel, and they both can recover their funds.
In this commit we modify the integration tests slightly, by setting the
parties that gets breached during the breach tests to --nolisten. We do
this to ensure that once the data protection logic is in place, they
nodes won't automatically connect, detect the state desync and recover
before we are able to trigger the breach.
This commit makes sure the channels that are force closed also are put
into the state "waiting close" before the commitment transaction is
confirmed, and exits this state when it confirms.
This was previously not checked, as this check was added before the
"waiting close" state was introduced.
This commit fixes a flake within the integration tests, where we would
mine a set of blocks before checking if Bob's sweep tx was in the
mempool. Usually this would pass since the blocks were generated before
the tx hit the miner's mempool, but sometimes it was mined and then we
would check the mempool.
This commit fixes this by correctly waiting immediately for Bob to sweep
his funds, as they are not time locked.
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.
In this commit, we modify the graph topology notifications test to wait
until a graph update notification has been received for a closed
channel, rather than assume the next graph update will be for the closed
channel itself.
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.
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.
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.
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 extend the testRevokedCloseRetributionRemoteHodl so
that the final broadcast revoked transaction has incoming *and* outgoing
HTLC's. As is, this test fails as there's a lingering bug in the way we
generate htlc resolutions. A follow up commit will remedy this issue.
In this commit, we modify the sphinx replay test to actually force close
that final channel. We do this, as otherwise, we'll now reject the co-op
close attempt as the channel still has active HTLCs.
This commit is a follow up to the prior commit which fixed a rounding
error bug in lnwallet. For uniformity, we also fix other occurrences in
the breach arbiter, as well as the integration tests.
This commit removes two unnecessary disconnect/reconnect attempts
from the switch itest. Both occur after the primary test has been
completed, and were being executed before doing a final sanity check
that the path is still usable. Nothing about the test behavior should
change.
This commits removes many of the timeout-based consistency
checks, which tend to be less dependable on Travis. They
have been replaced with stronger WaitPredicates, and the new
WaitInvariant where appropriate. This should give provide a
much greater degree of reliability in our highly-variant
testing environments.
// 1. Carol --> Dave --> Alice --> Bob forward payment
// 2. Carol --- Dave X Alice --- Bob disconnect intermediaries
// 3. Carol --- Dave X Alice <-- Bob settle last hop
// 4. Carol --- Dave X X shutdown Bob, restart Alice
// 5. Carol <-- Dave <-- Alice X expect settle to propagate
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.
