Makes the helper methods for constructing witness script
hash and to-local outputs. This will allow watchtowers to
import and reuse this logic when sweeping outputs.
In this commit, we update the generateSphinxPacket to use newLogClosure
to delay the spew evaluation until log print time. Before this commit,
even if we weren't on the trace logging level, the spew call would
always be evaluated.
In this commit, we fix a slight regression that happened when the
sendtoroute RPC call was implemented. As a result of the refactoring,
the debughtlc mode silently broke. In this commit, we fix this by
checking against the zero hash, rather than the length of the payment
hash, as since we use a fixed sized byte slice, it will always be zero.
This commit corrects the distribution used to
schedule a link's randomized backoff for fee
updates. Currently, our algorithm biases the
lowest value in the range, with probability
equal to lower/upper, or the ratio of the lower
bound to the upper. This distribution is skewed
more heavily as lower approaches upper.
The solution is to sample a random value in the
range upper-lower, then add this to our lower
bound. The effect is a uniformly distributed
timeout in [lower, upper).
In the event that the default Tor DNS host wouldn't resolve, it would
prevent `lnd` from starting due to the failed lookup. This should fail
silently as it's only crucial during bootstrapping. However, if the user
has explicitly modified this, we should let them know of the error
immediately.
In this commit, we modify the existing logic that would attempt to read
the min CLTV information from the invoice directly. With this route, we
avoid any sort of DB index modifications, as this information is already
stored within the payment request, which is already available to the
outside callers. By modifying the InvoiceDatabase interface, we avoid
having to make the switch aware of what the "primary" chain is.
In this commit, we fix a slight bug recently introduced by the addition
of the new signal package. As we now use a regular defer for many
actions, it may be possible that the logs aren't yet initialized (for
example, lnd -h), which can cause a panic if the shutdown procedure goes
to log before the logs have been initialized.
In this commit, a new weight function is introduced. This will create a
meaningful effect of time lock on route selection. Also, removes the
squaring of the fee term. This led to suboptimal routes.
Unit test added that covers the weight function and asserts that the
lowest fee route is indeed returned.
This comment extends the unit tests for NewRoute with checks
on the total time lock for a route as well as the expected time
lock values for every hop along the route.
This commit fixes the logic inside the newRoute function to
address the following problems:
- Fee calculation for a hop does not include the fee that needs
to be paid to the next hop.
- The incoming channel capacity "sanity" check does not include
the fee to be paid to the current hop.
This change makes the test more sensitive to bugs than a route
with nodes that all enforce the same fee policy.
In addition to that, the fee has been increased to a level
at which potential problems with improper fee calculation
become detectable (and not disappear in rounding).
In this commit, we update all the lncfg methods used to properly pass in
a new resolver. This is required in order to ensure that we don't leak
our DNS queries if Tor mode is active.
