Previously, we'd always add up to the maximum number of hop hints
(and beyond!) when selecting hop hints in our first pass. This
change updates hop hint selection to always stick to our hop hint
limit, and to the "hop hint factor" that we scale our invoices by.
This change will result in selecting fewer channels in our first
pass if their total inbound capacity reaches our hop hint factor.
This prevents us from revealing as many private channels as
before, but has the downside of providing fewer options for
payers.
Update our test to assert that we have hop hints present when we
expect them, and fix the "alice is a private node" issue that was
previously preventing us from adding hop hints. Asserting that we
have hop hints present in this itest ensures that we'll fail our
itests if a change to SelectHopHints results in our no longer
having hints in this secnario.
This updates the description that is provided for `lncli state` to match
the states that are currently returned by lnd. `RPC_READY` no longer
exists and is replaced by `RPC_ACTIVE` with a revised description, and
`SERVER_ACTIVE` is added as the status that indicates lnd is fully
ready to accept RPC calls.
See `enum WalletState` in `stateservice.proto`.
In this commit, we increase the legacy fee limit threshold (the amount
below which we'll allow 100% of funds to go to fees for the non-v2 RPC
calls) from 50 sats to 1k sats.
If we're signing for an UTXO that isn't known to the wallet, then the
UTXO's pk script _must_ be set in the sign descriptor. Otherwise we run
into a generic PSBT serialization error when running in a remote signing
setup.
In this commit, we expose a new monitoring option to allow users to
export gRPC performance metrics. These metrics can be used to see how
long certain calls are taking, the total amount of time spent handling
calls, broken down by service and also call.
This option consumes additional memory and disk space for the Prometheus
server, which is why we're opting to make it an optional flag.
The API doc generator failed after merging #6149 because of the `lncli
importgraph` tag in the proto file.
We could also fix the API doc generator by adding the "dev" build tag,
but not including any dev only features in the API docs is probably the
preferred path.
`rpc-check` is used in our CI pipeline to detect any difference
between the committed and the automatically generated rpc files.
Unfortunately, the current method only detects changes in the
already existing files and won't fail if `make rpc` generates
a totally new file.
`git status --porcelain` makes the trick, it returns a line for
each file that has been modified, created or deleted.
