We now redirect the mineBlocks function to the mineBlocksSlow function
which waits after each mined block. To reduce the overall time impact of
using that function everywhere, we only wait 20 milliseconds instead of 50ms
after each mined block to give all nodes
some time to process the block. This will still slow down everything by a bit
but reduce flakes that are caused by different sub systems not being
up-to-date.
The latest version of btcd allows its stall handler to be disabled. We
use that new config option to make sure the mining btcd node and the lnd
chain backend btcd node aren't disconnected if some test takes too long
and no new p2p messages are exchanged.
This commit adds a fetchMinMempoolFee function to the BitcoindEstimator
that fetches the current min mempool fee from the bitcoind backend. The
commit then also updates the BitcoindEstimator to use a minFeeManager
for it's minFeeManager member and uses the fetchMinMempoolFee function
to initialise this.
The validateFeeRate function uses the availableBalance function to get
the current spendable balance of a channel, adds the old fee and then
ensures that the new fee is not larger than the amount we have available
to spend. This commit also removes the local reserve check in the
validateFeeRate function since the balance returned from
availableBalance already takes the local reserve into acccount.
In this commit we ensure that the max fee calculated in the MaxFeeRate
function takes the local reserve amount into account along with any
pending HTLCs. This is done by calling the avaialbeBalance function.
In this commit, a subscription is made to topology updates. For any
NodeAnnouncements received for our peristent peers, we store their newly
advertised addresses. If at the time of receiving these new addresses
there are any existing connection requests, these are updated to reflect
the newly advertised addresses.
In this commit we demonstrate a bug to show that if an inbound peer
changes their listening address to one not advertised in their original
NodeAnnouncement then we will not be able to reconnect to them. This bug
will be fixed in a follow-up commit.
This commit just ensures that we fetch the lastest advertised addresses
for a peer from the db for both inbound and outbound peers. The reason
for seperating this into its own commit is to make future commits in
this PR easier to review.
The point of this commit is to make future commits in the same PR easier
to review. All that this commit does is exit early if the peer we are
considering is not persistent instead of having a bunch of logic
indented in an if-clause.
This commit adds an itest to demonstrate that if a peer advertises
multiplie external IP addresses, then they will not all be used to
reconnect to the peer during reconnection. This will be fixed in a
follow-up commit.
The assertNumConnection function currently takes in an 'expected' number
of connections argument and asserts that both alice and bob only each
only have that number of connections. So this fails to be useful if say
alice is also connected to charlie cause then if we call
assertNumConnections between alice and bob it will fail saying there are
2 connections between them since all it does is count alice's total
number of connections. This commit replaces this function with 2 new
functions: assertConnected which asserts that at least one connection
exists between two peers and assertNotConnected which asserts that no
connections exists between the two peers.
The FundingPsbtFinalize step is a safety measure that assures the final
signed funding transaction has the same TXID as was registered during
the funding flow and was used for the commitment transactions.
This step is cumbersome to use if the whole funding process is completed
external to lnd. We allow the finalize step to be skipped for such
cases. The API user/script will need to make sure things are verified
(and possibly cleaned up) properly.
During the final part of the channel funding negotiation we only need to
assemble the full funding TX with the witness if we are going to publish
the transaction ourselves. If the final funding TX is published
externally we don't need this information. This will make it possible to
skip the verify process for fully externally funded PSBT channels.
This commit makes SendHTLC (we are the source) evaluate the dust
threshold of the outgoing channel against the default threshold of
500K satoshis. If the threshold is exceeded by adding this HTLC, we
fail backwards. It also makes handlePacketForward (we are forwarding)
evaluate the dust threshold of the incoming channel and the outgoing
channel and fails backwards if either channel's dust sum exceeds the
default threshold.
