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.
This commit extends lncfg to support user specified database backend.
This supports configuration for both bolt and etcd (while only allowing
one or the other).
Variables related to the default configuration file location are
needed if the config parsing is happening externally. We export them
so they don't need to be copied to projects that use lnd as a library.
To allow external configuration parsing and validation, this commit
exports the function that checks a configuration for sanity.
Also because we touch the code, we need to fix all linter errors.
This provides users an alternative over the SAFECOOKIE authentication
method, which may not be as useful if users are connecting to a remote
Tor sevrer due to lnd not being able to retrieve the cookie file.
This commit enables the user to specify he is not interested in
automatically close channels with pending payments that their
corresponding htlcs have timed-out.
By requiring a configurable grace period uptime of our node
before closing such channels, we give a chance to the other node to
properly cancel the htlc and avoid unnecessary on-chain transaction.
In mobile it is very important for the user experience as otherwise
channels will be force closed more frequently.
This commit makes lnd recreate its TLS certificate if the config's
tlsextradomains or tlsextraips changed. This is useful, since earlier
user would have to manually delete the files to trigger lnd to recreate
them.
To ensure users don't accidentally have their TLS certificate recreated,
we gate it behind a flag --tlsautorefresh that defaults to false.
This commit adds handling code for the key send custom record. If this
record is present and its hash matches the payment hash, invoice
registry will insert a new invoice into the database "just in time". The
subsequent settle flow is unchanged. The newly inserted invoice is
picked up and settled. Notifications will be broadcast as usual.
This commit gets upfront shutdown scripts from openchannel and
acceptchannel wire messages sent from our peer and sets upfront
shutdown scripts in our open and accept channel messages when
the remote peer supports option upfront shutdown and we have
the feature enabled.
This commit beings the process of deprecating unsafe-disconnect. Many
moons ago this was disallowed to prevent concurency bugs surrounding
reconnect. Despite the name, it has been safe to enable this feature for
well over a year, as several PRs have been merged that addressed the
possible issues that existed when the feature was added.
