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.
ProcessLocalAnnouncement will attempt to call UpdateEdge with the new
policy. If we call it manually before handing it to the gossiper, that
call will fail with "Outdated" and the announcement won't propagate.
This commit fixes a small bug that could cause us to disconnect an
already connected peer if no addresses where provided to the ConnectPeer
method. Now we instead first check if we are already connected, and
return early.
In this commit, we refactor the existing connection logic outside of the
ChanController's OpenChannel method. We do this as previously it was
possible for peers to stall us while attempting to connect to them. In
order to remedy this, we now attempt to connect the peer before tracking
them in our set of pending opens.
In this commit, we add a new test to expose a lurking bug within the
graph database code. As is, when we go to delete a node from the
database, we don't also remove the entries within the update index. As a
result, if a user attempted to call NodeUpdatesInHorizon (or typically
as part of the p2p handshake), we would error out, as we would try to
read a node that no longer existed in the graph, as it was pruned.
In this commit, we fix a bug where it's possible that changing the
wallet's password fails due to not being able to remove non-existent
macaroon files. Since it's possible to run lnd without creating them,
changing the wallet's password would always result in a failure.
In this commit we fix a minor logging artifact. After the switch to
EdgePoint, the FilteredChainView implementations will try to log the
struct directly, as prior they would have an outpoint object. We restore
this behavior by adding a String() method to EdgePoint which will simply
proxy through to the outpoint so we can log that directly.
In this commit, we fix a slight bug in the existing implementation of
DeriveNextKey for btcwallet. Before this commit, we would only set the
public key, and not also the derivation path. It's important that we
also set the path information, as in the near future we'll be using the
KeyDescriptors returned from this method to create static channel back
ups. With these static backups, the key alone may be insufficient to
re-derive the private key as we may need to fallback to brute forcing in
order to re-derive the key as it's possible we add new key families in
the future.
In this commit, we fix a slight bug by ensuring that the revocation info
at the final state of the channel, as well as the local chan config is
properly set within the channel close summary created within
NewUnilateralCloseSummary. Before this commit, for all cooperative close
transactions, this state would _only_ include the pubkey itself, which
in some cases may not be sufficient to re-derive the key if needed.
Sometimes when performing an initial sync, the remote
node isn't able to pull messages off the wire because
of long running tasks and queues are saturated. With
a shorter write timeout, we will give up trying to send
messages and teardown the connection, even though the
peer is still active.
This commit adds asynchronous starting of peers,
in order to avoid potential DOS vectors. Currently,
we block with the server's mutex while peers exchange
Init messages and perform other setup. Thus, a remote
peer that does not reply with an init message will
cause server to block for 15s per attempt.
We also modify the startup behavior to spawn
peerTerminationWatchers before starting the
peer itself, ensuring that a peer is properly
cleaned up if the initialization fails. Currently,
failing to start a peer does not execute the bulk
of the teardown logic, since it is not spawned
until after a successful Start occurs.
This commit adds additional synchronization logic to
WaitForDisconnect, such that it can be spawned before
Start has been executed by the server. Without
modification, the current version will return
immediately since no goroutines will have been
spawned.
To solve this, we modify WaitForDisconnect to block until:
1) the peer is disconnected,
2) the peer is successfully started,
before watching the waitgroup.
In the first case, the waitgroup will block until all
(if any) spawned goroutines have exited. Otherwise, if
the Start is successful, we can switch to watching the
waitgroup, knowing that waitgroup counter is positive.
In a previous commit, we modified our fee rates to be sat/kw internally
as it was possible that the estimated fee rate was not enough to
properly broadcast the transaction. To remedy this, we decided to add a
fee floor, but this would only be enforced when querying the fee
estimator. In this commit, we attempt to do the same thing, but for fee
rates input manually by the user.
Tests for the case where a chain backend skips a series of blocks, such that the notifier's best block is out of date. Also tests the case where a notifier's best block has been reorged out of the chain.
This tests the case where a client registers for block notifications with an outdated best block, to ensure that the client is properly caught up on the blocks that it has missed.
Switches all ChainNotifier parameters to be TestChainNotifiers. This allows access to the extra testing methods provided by the TestChainNotifier interface.
TestChainNotifier wraps the ChainNotifier interface to allow adding additional testing methods with access to private fields in the notifiers. These testing methods are only compiled when the build tag "debug" is set. UnsafeStart allows starting a notifier with a specified best block.
UnsafeStart is useful for the purpose of testing cases where a notifier's best block is out of date when it receives a new block.
In this commit, we thread through a link's quit channel into
routeAsync, the primary helper method allowing links to send
htlcPackets through the switch. This is intended to remove
deadlocks from happening, where the link is synchronously
blocking on forwarding packets to the switch, but also
needs to shutdown.
This commit adds a test that verifies Stop does not block
if the link is concurrently forwarding incoming Adds to
the switch. This test fails prior to the commits that
thread through the link's quit channel.
