In this commit, in order to allow the caller to specify the amount that
was ultimately accepted for an invoice, the SettleInvoice method has
gained a new parameter: amtPaid. SettleInvoice will now populate the
final amount paid in the database upon db commit.
In this commit, we modify the InvoiceDatabase slightly to allow the link
to record what the final payment about for an invoice was. It may be the
case that the invoice actually had no specified value, or that the payer
paid more than necessary. As a result, it's important that our on-disk
records properly reflect this.
To fix this issue, the SettleInvoice method now also accepts the final
amount paid.
Fixes#856.
In this commit, we extend the current SubscribeInvoice streaming RPC
call. We add two new values to the InvoiceSubscription message:
add_index and settle_index. These fields have also been added to the
current Invoice message. Each time a new invoice is added, the add index
will be incremented. Each time a new invoice is settled the settle index
will be incremented. The new field on the InvoiceSubscription message
allow callers to specify the last add index and the last settle index
they know of. With this new addition, callers will now be able to
reliably receive notifications for new received payments.
Care has been taken to ensure that these changes are backwards
compatible. If callers don't specify either of the new fields, then they
won't receive any notification backlog at all.
Fixes#862.
In this commit, we alter the behavior of the regular
short channel id encoding, such that it returns a nil
slice if the decoded number of elements is 0. This is
done so that it matches the behavior of the zlib
decompression, allowing us to test both in using the
same corpus.
Modifies the behavior of the quick test for
MsgQueryShortChanIDs, such that the generated
slice of expected short chan ids is always nil
if no elements are returned. This mimics the
behavior of the zlib decompression, where
elements are appended to the slice, instead of
assigning to preallocated slice.
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.
