In this commit, we address an issue with our router mock in which it was
not properly storing and retrieving edge policies. Previously, they were
being appended to a slice of policies, but this doesn't always work like
when you attempt to update the same edge twice. Instead, the slice can
only contain up to two entries, each one being the latest version of
each direction.
lnd_test: adding address validation for send coins
The commit adds a test that checks that when a user calls sendcoins, the
receiving address is validated according to the current network. If the
address is not compatible with the current network, it will return an
error to the user.
rpcserver: adding a check for compatible network in SendCoins
This commit adds a check in SendCoins that checks whether the receiving
address is compatible with the current network.
Fixes#2677.
In this commit, we leverage the recently introduced zombie edge index to
quickly reject announcements for edges we've previously deemed as
zombies. Care has been taken to ensure we don't reject fresh updates for
edges we've considered zombies.
In this commit, we extend the graph's FetchChannelEdgesByID and
HasChannelEdge methods to also check the zombie index whenever the edge
to be looked up doesn't exist within the edge index. We do this to
signal to callers that the edge is known, but only as a zombie, and the
only information that we have about the edge are the node public keys of
the two parties involved in the edge.
In the event that an edge does exist within the zombie index, we make
an additional check on edge policies to ensure they are not within the
router's pruning window, indicating that it is a fresh update.
We mark the edges as zombies when pruning them to ensure we don't
attempt to reprocess them later on. This also applies to channels that
have been removed from the graph due to being stale.
In this commit, we add a zombie edge index to the database. This allows
us to quickly determine across restarts whether we're attempting to
process an edge we've previously deemed as zombie.
In this commit, we modify the primary `signal` package to instead catch
all signals. Before this commit, it would only catch the interrupt
signal sent from the kernel. With this new commit, we'll now also catch
(or attempt to catch): `SIGABRT`, `SIGTERM`, `SIGSTOP`, and `SIGQUIT`.
In this commit, we update the `btcwallet` dep to the latest version that
includes a fix related to zero conf spends. Before this new version, if
a single output was spent multiple time by conflicting transactions,
then upon removing them all after a new transaction confirms, a number
of zero conf UTXOs could be left over.
Bumps the default read and write handlers to be well
above the average number of peers a node has. Since
the worker counts specify only a maximum number of
concurrent read/write workers, it is expected that
the actual usage would converge to the requirements
of the node anyway. However, in preparation for a
major release, this is a conservative measure to
ensure that the default values aren't too low and
improve network instability.
In this commit, we add a 5 minute idle timer to
the write handler. After catching the write
timeouts, it's been observed that some connections
have trouble reading a message for several hours.
This typically points to a deeper issue w/ the peer
or, e.g. the remote peer switched networks. This now
mirrors the idle timeout used in the read handler,
such that we will disconnect a peer if we are unable
to send or receive a message from the peer after 5
minutes.
We also modify the readHandler to drain its
idleTimer's channel in the even that the timer had
already fired, but we successfully sent the message.
This commit reduces the peer's write timeout to 5s.
Now that the peer catches write timeouts and doesn't
disconnect, this will ensure we spend less time blocking
in the write pool in case others also need to access the
workers concurrently. Slower peers will now only block
for 5s, after every reattempt w/ exponential backoff.
This commit modifies the writeHandler to catch timeout
errors, and retry writes to the socket after a small
backoff, which increases exponentially from 5s to 1m.
With the growing channel graph size, some lower-powered
devices can be slow to pull messages off the wire during
validation. The current behavior will cause us to
disconnect the peer, and resend all of the messages that
the remote peer is slow to validate. Catching the timeout
helps in preventing such expensive reconnection cycles,
especially as the network continues to grow.
This is also a preliminary step to reducing the
write timeout constant. This will allow concurrent usage
of the write pools w/out devoting excessive amounts of
time blocking the pool for slow peers.

This commit increase the expiry grace delta to a value above the
broadcast delta. This prevents htlcs from being accepted that would
immediately trigger a channel force close.
A correct delta is generated in server.go where there is access to
the broadcast delta and passed via the peer to the links.

Previously there was no minimum remaining blocks requirement on
forwarded htlcs, which may cause channel arbitrator to force
close the channel directly after forwarding the htlc.

The multiplier doesn't make sense because funds may be equally at risk
by failing to broadcast to chain regardless of whether the HTLC is a
redeem or a timeout.
