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.
This commit fixes a lingering bug that could at times cause
incompatibilities with other implementations when attempting a
cooperative channel close. Before this commit, we would use a pointer
to the funding txin everywhere. As a result, each time we made a new
state, or verified one, we would modify the sequence field of the main
txin of the commitment transaction. Due to this if we updated the
channel, then went to do a cooperative channel closure, the sequence of
the txin would still be set to the value we used as the state hint.
To remedy this, we now copy the txin each time when making the
commitment transaction, and also the cooperative closure transaction.
This avoids accidentally mutating the txin itself.
Fixes#502.
This commit fixes a deadlock that could occur when
a peer disconnected during a call to sentToPeer. In
This particular case, a message would successfully
be queued, the peer would shutdown, and we would
block waiting for an error to be returned on the
message's error channel, which would deadlock.
This fixes that by also checking for peer shutdown.
In this commit, we modify the CloseChannel to wait for both nodes to
detect that channel as being active before we attempt to close it. This
should serve to reduce many of the flakes that we’ve been seeing on
travis which were caused by node A detecting the channel as active, but
node B not, leading to a test flake under certain timing conditions.
The new function uses the recently added WaitPredicate method.
