Add a new subpackage to `lnd/channeldb` to hold some of the types that
are used in the package itself and in other packages that should not
depend on `channeldb`.
We deprecate `QueryProbability`, as it displays the same information as
`QueryMissionControl` less the probability. `QueryRoutes` still contains
the total probability of a route.
Extends the pathfinder with a capacity argument for later usage.
In tests, the inserted testCapacity has no effect, but will be used
later to estimate reduced probabilities from it.
Add additional comment to `lnclic addinvoice`'s `--private` flag warning
about including a large number of private channel hints when using zero
ammounts.
Also added a comment to the `private` field in the `Invoice` proto
message.
With this change we allow adding hop hints when adding an invoice, even
if its amount is zero.
A couple of new unit test case have been added, and the
`testInvoiceRoutingHints` itest was expanded to account for this
scenario.
In this commit, we start making use of the new ListClientSession
functional options added in the previous commit. We use the functional
options in order to calculate the max commit heights per channel on the
construction of the tower client. We also use the options to count the
total number of acked and committed updates. With this commit, we are
also able to completely remove the AckedUpdates member of the
ClientSession since it is no longer used anywhere in the code.
In order to reduce the number of calls to the db we try to process as
few channels as we can + try to not do extra work for each of them.
- First fetch all the channels. Then, filter all the public ones and
sort the potential candidates by remote balance.
- Filter out each potential candidate as soon as possible.
- Only check the alias if the channel supports scid aliases.
- Because we sort the channels by remote balance, we will hit the
target amount, if possible, as soon as we can.
We do not want to leak information about our remote balances, so we
shuffle the hop hints (the forced ones go always first) so the invoice
receiver does not know which channels have more balance than others.
Lists with non-primitive members aren't supported in the query string of
a GET request with the current version of the grpc-gateway library. To
allow route_hints to be set through REST, we also offer a POST endpoint
for that call where the encoding of the request parameter can be
specified as JSON.
Test stream cancellation of the TrackPayments rpc call. In order to achieve
this, ControlTowerSubscriber is converted to an interface, to avoid trying to
close a null channel when closing the subscription. By returning a mock
implementation of the ControlTowerSubscriber in the test that problem is
avoided.
