In this commit, we add an additional case when handling a failed
commitment signature. If we detect that it’s a InvalidCommitSigError,
then we’ll send over an lnwire.Error message with the full details. We
don’t yet properly dispatch this error on the reciting side, but that
will be done in a follow up a commit.
In this commit, we add a new detailed error that’s to be returned
when/if the remote peer sends us an invalid commit signature. The new
error contains the transaction that we attempted to validate the
signature over, the sighs, and the state number. Returning this
additional information will serve to aide in debugging any
cross-implementation issues.
In this commit, we modify the logic within the Stop() method for
msgStream to ensure that the main goroutine properly exits. It has been
observed on running nodes with tens of connections, that if a node is
very flappy, then the node can end up with hundreds of leaked
goroutines.
In order to fix this, we’ll continually signal the msgConsumer to wake
up after the quit channel has been closed. We do this until the
msgConsumer sets a bool indicating that it has exited atomically.
In this commit, we fix a lingering protocol level bug when reporting
errors encountered during onion blob processing. The spec states that
if one sends an UpdateFailMalformedHtlc, then the error reason MUST
have the BadOnion bit set. Before this commit, we would return
CodeTemporaryChannelFailure. This is incorrect as this doesn’t have the
BadOnio bit set.
Prior to this commit, the final close summary we added to the database
for the initiator of the channel was incorrect. This is due to the fact
that before, we would use the final snapshot to determine how many
coins the local party was delivered as a result of the cooperative
closure transaction. This is incorrect, as the local party pays fees on
the closure transaction if it’s the initiator.
To remedy this, we’ll now use the new return value of
CompleteCooperativeClose to properly note our final balance in the
database.
In this commit, add an additional return value to
CompleteCooperativeClose. We’ll now report to the caller our final
balance in the cooperative closure transaction. We report this as
depending on if we’re the initiator or not, our final balance may not
exactly match the balance we had in the last state.
In this commit, we remove the blocks_till_open from
PendingChannelsResponse as in its current state, the values that are
assigned to this field don’t accurately reflect the naming. This has
caused a good bit of confusion amongst users lately. As a result, we’re
temporarily removing this field until we have proper incremental
notifications within the chain notifier.
In this commit, we add a new runtime assertion to ensure that the
backed btcd node (if this mode is active) has the proper indexes set
up. Atm, if btcd isn’t running with the txindex active, then the
current ChainNotifier implementation will be unable to properly handle
certain classes of historical notification dispatches.
In order to test that the running btcd node is configured properly,
we’ll fetch the latest block, then try to query a transaction within
that block using the txindex. If btcd isn’t running with this mode
active, then the request will fail. In this case, we’ll then fail to
start lnd with an error.
Fixes#525.
This commit adds a new test, that in a small network
of 4 nodes, tests that a private channel can be used
for routing payments by the endpoints of the channel,
while the existence of the channel is not known to
the rest of the network.
Peers are treated as transient by default. When a peer is disconnected,
no attempt is made to reconnect. However, if we have a channel open
with a peer that peer will be added as persistent. If a persistent peer
becomes disconnected then we will attempt to reconnect.
This behavior implies that a fresh node - those without any channels -
will fall off the network over time as remote nodes restart or due to
connectivity changes. This change marks bootstrap peers as persistent
and ensures that the node remains connected to those specific peers over
time. This does not keep the node connected in the case that all
bootstrap peers are down.
Fixes#451.
In this commit, we modify the way the link handles HTLC’s that it
detects is destined for itself. Before this commit if a payment hash
came across for an invoice we’d already settled, then we’d gladly
accept the payment _again_. As we’d like to enforce the norm that an
invoice is NEVER to be used twice, this commit modifies that behavior
to instead reject an incoming payment that attempts to re-use an
invoice.
Fixes#560.
In this commit we rename the lnrpc.PendingChannelRequest and
lnrpc.PendingChannelResponse to
lnrpc.PendingChannelsRequest/lnrpc.PendingChannelsResponse. We do this
as we strive to ensure that the naming scheme across the RPC interface
is consistent.
This commit makes sure we are not attempting to create a
channel announcement with a nil ChannelAuthProof, as that
could cause a crash at startup whe the gossiper would
attempt to reprocess an edge coming from the fundingmanager.
It also makes sure we check the correct error returned from
processRejectedEdge.
In this commit, we modify the Broadcast to take a *set* of peers to
skip, rather than just a single peer. We make this modification as when
a new channel is discovered, it’s likely the case that we get the
announcement from several peers rather than a single peer. With this
change, we’ll ensure that the caller (who is aware of the set of
senders) is able to properly avoid wasting bandwidth by re-sending the
message to all peers that sent it to us originally.
In this commit, we make an incremental step towards page of the new
feature of deDupedAnnoucnements to return the set of senders for each
message. All methods the process new channel announcements, will now
return an instance of networkMsg rather than lnwire.Message. This will
allow passing the returned announcement directly into
deDupedAnnoucnements.AddMsg().
In this commit, we modify the deDupedAnnouncements struct slightly. The
element of this struct will now keep track of the set of senders that
sent a particular message. Each time a message is added, we’ll replace
the new message with the old (as normal), but we’ll also add the new
sender to the set of known senders.
With this new feature, we’ll be able to avoid re-sending a message to
the peer that sent it to us in the first place.
In this commit, we add additional detail in the error return hen were’e
unable to properly decode an encapsulated error. This additional
logging was added with the goal of being able to track down a lingering
bug, where at times lnd cannot decode a TemporaryChannelFailure
message.
