This commit fixes an existing bug wherein we would blank out a node’s
color instead of properly setting the field when syncing graph state
with another node This would cause the node to reject the node
announcement and we would generate an we would invalidate the signature
of the node announcement. We fix this simply by properly setting the
node announcement.
In this commit, we fix an existing bug when processing new node
announcement. Before this commit, we wouldn’t also copy over the color
field of a node’s announcement. As a result, when went to synchronize
our graph state with that of a connecting peer, we would generate an
invalid node announcement. We fix this by properly setting the color
field of a node.
In this commit, we fix a bug that would cause the DNS seeds to be
*always* active regardless of which chain+network we were on. Before we
would look up the network in the reverseChainMap. However, if we were
on regtest or testate, then it would still (incorrectly) resolve to a
valid hash.
To remedy this, we now directly use the genesis hash of the current
active chain.
This new field was added as a recent modification to the spec, but the
curve parameter within the attribute wasn’t set to nil. As a result
this would result in a large degree of spam within the logs when set to
trace mode. This commit fixes this issue by setting it to nil along
with all the other pub keys within messages.
In this commit, we implement a recent spec change that require nodes to
advertise the minHTLC of the remote node within their ChannelUpdate. We
do this as it will be the remote node which carries the HTLC towards
us, therefore we should advertise *their* minHTLC value.
In this commit, we now properly examine the Flag field within the
ChannelUpdate message as a bitfield. Before this commit we would
manually check the flags for zero or one. This was incorrect as a their
bit has now been defined. To properly dispatch the messages, we’ll now
treat it properly as a bitmask.
In this commit, we fix an existing bug within the
createChanAnnouncement function. Before we would set the flag to be 0,
or 1 depending on which edge it was. This was incorrect as since then
additional flags have been defined. We now properly set the entire
flag, rather than taking a shortcut. With this, we’ll properly
advertise all ChannelUpdate announcements.
In this commit, we implement adherence of the disabled bit within a
ChannelUpdate during path finding. If a channel is marked as disabled,
then we won’t attempt to route through it. A test has been added to
exercise this new check.
In this commit, we update path finding to skip an edge if the amount
we’re trying to route through it is below the MinHTLC (in mSAT) value
for that node. We also add a new test to exercise this behavior. In
order for out test to work properly, we’ve modified the JSON to make
the edge to Goku have a higher min HTLC value.
In this commit, we add a new type to the lnwire package:
ChanUpdateFlag. This type represent the bitfield that’s used within the
ChannelUpdate message to give additional details as how the message
should be interpreted.
It dictates in the spec, that the error message should be an ASCII
string to allow other implementations to easily discern the type of
error. The other implementations do this, but we don’t yet, but we’ll
go ahead and display it anyway as it’s helpful when debugging.
In this commit, we fix an existing bug within the EstimateFeePerWeight
method for the BtcdFeeEstimator. If the sat/byte value returned was too
low, then it was possible for us to end up with a zero valued
sat/weight. We correct this issue by detecting, and falling back to the
default fee rate if so.
In this commit, we modify the high value passed into UpdateFilter upon
restart. Before this commit, we would pass in the prune height, which
would cause a full rescan within the FilteredChainView if the best
height as > than the prune height. This was redundant as we would
shortly carry out a manual rescan in the method below. To fix this, we
now pass in the bestHeight, this isn’t an issue as the
syncGraphWithChain method will manually scan up to that best height.
In this commit, we add a new abstraction, the ValidationBarrier. This
struct will be used to allow parallel validation of announcements
within notes AuthenticatedGossiper as well as the ChannelRouter.
Naively validating the announcement in parallel would run into issues
as it would be possible for validate an update announcement, before
validating the channel announcement itself. We solve this by creating a
waiting dependance using the ValidationBarrier to ensure that the
defendant jobs wait until their parents have been full validated.
In this commit, we fix an existing bug within our cooperative channel
closing transaction generation. Before this commit, we wouldn’t account
for the fee already allocated within the commitment transaction. As a
result, we would calculate the evaluated balance considering the fee
incorrectly. In this commit, we fix this by adding the commitment fee
to the balance of the initiator when crafting the closing transaction
In this commit we correct an off by one error on the Shutdown and
ClosingSigned message types. Additionally, we fix an error related to
the numbering of the UpdateFee message. With this we, gain proper
compatibility with the other implementations when it comes to
commitment hygiene, and also the cooperative closure process.
