- Extend SendRequest and QueryRoutesRequest protos
- newRoute function takes fee limit and cuts off routes that exceed it
- queryRoutes, payInvoice and sendPayment commands take the feeLimit inputs and pass them down to newRoute
- When no feeLimit is included, don't enforce any feeLimits at all (by setting feeLimit to maxValue)
In this commit we fix an existing bug which could cause internal state
inconsistency between then switch, funding manager, and the peer. Before
this commit, we would _always_ add a new channel to the channelManager.
However, due to recent logic, it may be the case that this isn't the
channel that will ultimately reside in the link. As a result, we would
be unable to process incoming FundingLocked messages properly, as we
would mutate the incorrect channel in memory.
We remedy this by moving the inserting of the new channel into the
activeChannels map until the end of the loadActiveChannels method, where
we know that this will be the link that persists.
In this commit, we fix a bug in the way we handle removing items from
the interfaceIndex. Before this commit, we would delete all items items
with the target public key that of the peer that owns the link being
removed. However, this is incorrect as the peer may have other links
sill active.
In this commit, we fix this by first only deleting the link from the
peer's index, and then checking to see if the index is empty after this
deletion. Only if so do we delete the index for the peer all together.
In this commit, we modify the interfaceIndex to no longer key the second
level of the index by the ChannelLink. Instead, we'll use the chan ID as
it's a stable identifier, unlike a reference to an interface.
In this commit, we fix the logging when adding new gossip syncers. The
old log would log the byte array, rather than the byte slice. We fix
this by slicing before logging.
This commit adds a poll 20 ms interval to WaitPredicate, similar to what
is done for WaitInvariant. This makes the predicate not being checked
super-rapidly, potentially filling the logs with useless info over the
wait predicate interval.
In this commit, we finish the fix for the inbound/outbound peer bool in
the server. The prior commit forgot to also flip the inbound/output maps
in Inbound/Outbound peer connected. As a result, the checks were
incorrect and could cause lnd to refuse to accept any more inbound
connections in the case of a concurrent connection attempt.
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.
In this commit, we ensure that if we're already ignoring a connection,
then we also ignore the pending persistent connection request.
Otherwise, we'll move to accept the replaced connection, but then
continue to attempt connection requests.
In this commit, we modify the look up for inbound peers to ensure that
we connect to the "freshest" address until we need to execute the
peerTerminationWatcher. We do this as it's possible for a channel to be
created by the remote peer during our session. If we don't query for the
node's address at the latest point, then we'll miss this new node
announcement for the node.
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 changes the gossiper to direct messages to
peer objects, instead of sending them through the
server every time. The primary motivation is to reduce
contention on the server's mutex and, more importantly,
avoid deadlocks in the Triangle of Death.
In this commit, we ensure that the packet queue will always exit, by
continually signalling the main goroutine until it atomically sets a
bool that indicates its has been fully shutdown. It has been observed
that at times the main goroutine will wake up (due to the signal), but
then bypass the select and actually miss the quit signal, as a result
another signal is required. We'll continue to signals in a lazy loop
until the goroutine has fully exited.
This commit moves the generic interface for
Lightning Network peers so that it can be
imported directly into the switch and gossiper.
Eventually, the majority of the peer logic
would be moved into this package for testing
and modularization.
In this commit we modify the existing sendtoroutes command such that
users can either specify the route over stdin (using the special '-'
flag), via the keyword argument, or via the positional argument.
In this commit, we modify the logic for the two primary payment related
RPCs to reduce duplication, indentation, and consolidate logic. As a
result, we'll now accept rpcPaymentIntents, turn those into regular
paymentIntents (convert from proto) before finally dispatching via
unified function.
