Extend lncli with a flag that indicates the intention to send
a spontaneous payment. lncli will generate a preimage/hash combination
and send the preimage as a custom record to the recipient.
This commit swaps out golang/protobuf/jsonpb for a custom variant that
by default prints byte slices as hex, which is more useful for our
setting. Some existing wrapper structs are removed as they can now be
printed directly with the new jsonpb.
!!! NOTE !!!
This commit introduces a breaking change to lncli listinvoices since
payment hashes and preimages will now be printed in hex instead of
base64.
* pass amt and amt_msat to rpc, letting server give an error if both
are present
* take amt from an extra argument if neither amt nor amt_ms are present
Probabilities are no longer returned for querymc calls. To still provide
some insight into the mission control internals, this commit adds a new
rpc that calculates a success probability estimate for a specific node
pair and amount.
With a separate proto message, it becomes possible to also return the
pair data for a single pair. This prepares for the new mc probability
querying rpc.
Probability estimates are amount dependent. Previously we assumed an
amount, but that starts to make less sense when we make probability more
dependent on amounts in the future.
Here we set start_time to 24 hours prior
if it's not provided on the CLI. The
effect of this is when you don't provide
a start_time:
CLI: -24h
RPC: Unix Epoch
Fixes https://github.com/lightningnetwork/lnd/issues/3357. When
start_time isn't specified, its default value is 0. This meant when
users explicitly specified a start_time of 0, we would incorrectly set
start_time to 24 hours in the past. Now, n0 means n0.
ListenerCfg allows passing custom listeners to the main method, to be
used for the wallet unlocker and rpc server. If these are set these will
be used instead of the regular RPC listeners.
This commit modifies paymentLifecycle so that it not only feeds
failures into mission control, but successes as well.
This allows for more accurate probability estimates. Previously,
the success probability for a successful pair and a pair with
no history was equal. There was no force that pushed towards
previously successful routes.
Previously mission control tracked failures on a per node, per channel basis.
This commit changes this to tracking on the level of directed node pairs. The goal
of moving to this coarser-grained level is to reduce the number of required
payment attempts without compromising payment reliability.
