Expose the ability to add blinded paths to an invoice. Also expose
various configuration values.
We also let the lncfg.Invoices struct satisfy the Validator interface so
that we can verify all its config values in one place.
This commit adds a new group config `BudgetConfig` to allow users
specifying their own preference when sweeping outputs. And a new config
option `NoDeadlineConfTarget` is added in case the user wants to use a
different "lazy" conf target.
Add an option to disable route blinding, failing back any HTLC with
a blinding point set when we haven't got the feature enabled.
Note that this commit only handles the case where we're chosen as the
relaying node (where the blinding point is in update_add_htlc), we'll
add handling for the introduction node case once we get to handling of
blinded payloads).
This commit removes the `Litecoin`, `LtcMode` and `LitecoindMode`
members from the main LND `Config` struct. Since only the bitcoin
blockchain is now supported, this commit also deprecates the
`cfg.Bitcoin.Active` config option.
In this commit, we add the ability to obtain blocking and mutex
profiles. The blocking profile will show which goroutines are
consistently blocked on synchronization primitives like channels, or
I/O. The mutex profile will show which mutexes are very contested.
The blocking profile can be enabled with a new arg: `--blockingprofile`.
The mutex profile can be enabled with a new arg: `--mutexprofile`. These
are both ignored if the profile port isn't set.
Activating these profiles requires the caller to pass in a sampling
rate. For now I've set it just to `1` to test things out. Unfortunately
documentation is rather scarce, so there aren't any good guides re what
these values should be set to. AFAICT, these add more overhead than the
other prowling options, so they shouldn't necessarily be enabled
persistently in production.
If there is only one entry in the sample-lnd.conf, it must reflect the
default value. If additional examples are provided, they should follow
the following format.
; Default:
; option=defaultvalue
; Example
; option=examplevalue
Booleans have been changed to 'false' to align with the default behavior
of Go. Additionally, the description for various parameters has been
adjusted.
This commit removes the `PrivateTowerURIs` member from the `WtClient`
config struct. This field has been deprecated since v0.8.0-beta and
currently, LND would fail to start if the field was specified.
In this commit, we increase the default CTLV value to 80 blocks.
Initially this was set to 144 blocks in the early days, but then was
lowered to 40 blocks as the lnd implementation matured. By setting this
to a higher value, we increase the safety window (MTTR) when it comes to
node downtime, and also add some buffer room around time locks which may
become more stressed in the future assuming the current mempool load
remains persistent.
We make the capacity factor configurable via an lnd.conf routerrpc
apriori parameter. The capacity factor trades off increased success
probability with a reduced set of channel candidates, which may lead to
increased fees. To let users choose whether the factor is active or not,
we add a config setting where a capacity fraction of 1.0 disables the
factor. We limit the capacity fraction to values between 0.75 and 1.0.
Lower values may discard too many channels.
In this commit, a new `--db.no-rev-log-amt-data` flag is added. The
config option is passed though to everywhere that it will be used. Note
that it is still a no-op in this commit. An upcoming commit will make
use of the flag.
