The constructor functions have no additional logic other than passing
function parameters into struct fields. Given the large function
signatures, it is more clear to directly construct the htlcPacket in
client code than call a function with lots of positional arguments.
This commit adds a small cancellation check to the
invoice subscription integration test. Calls to
Fatalf were observed on travis after the test had
ended stemming from the subscriber's goroutine,
which could happen if the subscription is late.
It also extends the timeout on the test from 5 to
10 seconds.
In this commit, we ensure that we actually advertise our desired value
for the smallest HTLC we’ll accept as incoming. Before this commit, the
value advertised was always zero.
Before this commit, during a reservation, we wouldn’t ever specify our
minHTL value. We don’t yet fully validate all channel constrains, but
doing this now serves to ensure that once those features are merged,
we’ll actually be setting a valid value for minHTLC.
This commit reorders logic in the peer termination
watcher such that we short circuit earlier if we
already have pending persistent connection requests.
Before, the debug statement may have indicated that
a reconnection was being attempted, even though it
may have exited before submitting the request to
the connection manager.
In this commit, we update the commits in the glide files to point to
the latest versions of bcd and neutrino. The latest btcd version
contains a fix to the connmgr to allow us to actually cancel connection
requests. The latest neutrino commit fixes an existing bug in the order
of block connected requests
In this commit, we fix an existing bug that would cause funding
transaction to be broadcast without any fees attached at all. This is
only an issue if the fee rate reported is extremely so, as can happen
on testnet. In this case, when we went to scale down to sat/weight, we
would return a value of zero due to integer division. If we went via
the EstimateFeePerWeight call directly, then it would've been detected.
However, we accept the fee/byte from the user directly on the command
line this wasn't being done.
To fix this, we'll now manually set the fee to a sane value, if it
returns a value that can't properly be scaled to fee/weight.
In this commit, we modify the existing logic to handle
UpdateFailMalformedHLTC message from an incoming peer. Rather than fail
the Chanel if they give us an invalid failure code, we’ll instead treat
it as a temporary channel failure so we can continue to forward the
error.
This commit adds an overlooked case into the main type switch statement
within the peer’s readHandler. Before this commit, we would fail to
process any UpdateFailMalformedHTLC messages, possibly leading to a
commitment desynchronization. To avoid this case, we’ll no properly
process the UpdateFailMalformedHTLC message by sending the message to
an active link registered to the switch.
In this commit, we extend the ProcessChanSyncMsg to detect a case where
we don’t have the necessary revocation window to send out a new commit.
This can arise if the remote party sends us a new state, but we haven’t
yet fully processed their FundingLocked message yet, so we would be
unable to create a new commitment state.
We fix this by enumerating each of our actions in the case of an error.
If we get ErrNoWindow, then this indicates that we can’t give the
remote party the commitment we would like to optimistically send over.
This isn’t an issue though, as in the next round, we’ll resynchronize
our state.
In this commit we fix a cosmetic bug within our RPC output for list
channels. We have a policy of always showing SAT instead of mSAT
externally. This led to user confusion, as if Alice or Bob ended up
with a fractional amount of satoshis, then the sum of trimmed amount
would be silently sent to miner’s fees. An example being: Alice ending
up with `8998999 mSAT` (`8998.999 SAT`). Bob similarly ends up with
`1001001 mSAT` (`1001.001 SAT`). `8998.999 + 1001.001 = 10000.0 SAT`.
However, we can't express that fractional amount (totaling `1 SAT`
across both commitment transactions) so it goes to miner fees.
To remedy this on the RPC interface level, we’ll now detect if we have
a dangling satoshi, and properly list it as going towards the miner fee
on the commitment transaction.
Fixes#468.
This commit is a follow up to a prior commit which skipped sending the
commitment sig message (and sending out the update fee) message if the
channel wasn’t yet able to forward any HTLC’s. We’ll modify the prior
commit to not add the fee update to the channel at all. Otherwise, we
risk a state desynchronization.
In this commit, we fix an existing bug that would cause issues within
the switch due to a value not being properly set. Before this commit we
would copy a byte array into a slice without first creating the
necessary capacity for that slice. To fix this, we’ll now ensure that
the blob has the proper capacity before copying over. Several tests
have been updated to always set a fake onion blob.
In this commit, we extend the initial check within SignNextCommitment
to bail out early if we don’t yet know the commitment point of the
remote party. This prevents a class of nil pointer panics if we attempt
to create a new state without yet having received the FundingLocked
message.
This commit adds a check to `updateChannelFee` which skipssending the
`update_fee` message when the channel is not eligable for forwarding
messages (likely due to the channel's `RemoteNextRevocation` not yet
being set).
This addresses #470.
This commit adds additional documentation to the sample-lnd.conf, and
also ensures that users are able to drop it in without any issues. The
prior version left the namespace off several of the arguments, rendering
it unusable.
Fixes#462.
In this commit, we fix an existing bug within the logic of the neutrino
notifier. Rather than properly dispatching only once a transaction had
reached the expected number of confirmations, the historical dispatch
logic would trigger as soon as the transaction reached a single
confirmation.
This was due to the fact that we were using the scanHeight variable
which would be set to zero to calculate the number of confirmations.
The value would end up being the current height, which is generally
always greater than the number of expected confirmations. To remedy
this, we’ll now properly use the block height the transaction was
originally confirmed in to know when to dispatch.
This also applies a fix that was discovered in
93981a85c0b47622a3a5e7089b8bca9b80b834c5.
In this commit, we extend the existing historical dispatch test case to
detect any instances of early dispatches. This catches a class of bug
within a ChainNotifier when the notifier will *always* dispatch early
no matter the number of confirmations. Currently, this test fails for
the neutrino notifier.
This commit fixes an existing bug wherein we would incorrectly attempt
to forward and HTLC to a link that wasn’t yet eligible for forwarding.
This would occur when we’ve added a link to the switch, but haven’t yet
received a FundingLocked message for the channel. As a result, the
channel won’t have the next revocation point available. A logic error
prior to this commit would skip tallying the largest bandwidth rather
than skipping examining the link all together.
Fixes#464.
In this commit, we modify the logWireMessage function to ensure that we
don't attempt to nil out the LocalUnrevokedCommitPoint.Curve field
unless it's actually set. We need to do this as the field as actually
optional, and we may be reading a message from a node that doesn't
support the option.
Fixes#461.
Before this commit, we wouldn’t properly set the TotalFees attribute.
As a result, our sorting algorithm at the end to select candidate
routes would simply maintain the time-lock order rather than also sort
by total fees. This commit fixes this issue and also allows the test
added in the prior commit to pass.
This commit is a follow up to the prior commit: as it’s possible for
the channel_reestablish message to be sent *before* the channel has
been fully confirmed, we’ll now ensure that we process it to the link
even if the channel isn’t yet open.
In this commit, we modify the logic within loadActiveChannels to
*always* load a channel, even if it isn’t yet fully confirmed. With
this change, we ensure that we’ll always send a channel_reestablish
message upon reconnection.
Fixes#458.
