Incoming htlcs that are timed out or failed (invalid htlc or invoice
condition not met), save a single on chain resolution because we don't
need to take any actions on them ourselves (we don't need to worry
about 2 stage claims since this is the success path for our peer).
Our current set of reports contain much of the information we will
need to persist contract resolutions. We add a function to create
resolver reports from our exiting set of resolutions.
To allow us to write the outcome of our resolver to disk, we add
optional resolver reports to the CheckPoint function. Variadic params
are used because some checkpoints may have no reports (when the resolver
is not yet complete) and some may have two (in the case of a two stage
resolution).
Add a new top level bucket which holds closed channels nested by chain
hash which contains additional information about channel closes. We add
resolver resolutions under their own key so that we can extend the
bucket with additional information if required.
In this commit, we add a new sub-system, then `HostAnnouncer` which
allows a users without a static IP address to ensure that lnd always
announces the most up to date address based on a domain name. A new
command line flag `--external-hosts` has been added which allows a user
to specify one or most hosts that should be periodically resolved to
update any advertised IPs the node has.
Fixes#1624.
This is useful when we wish to have a channel frozen for a specific
amount of blocks after its confirmation. This could also be done with an
absolute thaw height, but it does not suit cases where a strict block
delta needs to be enforced, as it's not possible to know for certain
when a channel will be included in the chain. To work around this, we
add a relative interpretation of the field, where if its value is below
500,000, then it's interpreted as a relative height. This approach
allows us to prevent further database modifications to account for a
relative thaw height.
Adds a new configuration flag to lnd that will keep keysend payments in
the accepted state. An application can then inspect the payment
parameters and decide whether to settle or cancel.
The on-the-fly inserted keysend invoices get a configurable expiry time.
This is a safeguard in case the application that should decide on the
keysend payments isn't active.
