A peer's remote address isn't known to us if we accepted the connection
over Tor, instead we know the address the onion service used to dial to
lnd. If said peer also doesn't have any advertised addresses, then we
don't have enough information to attempt a reconnect, so we avoid doing
so. Allowing the reconnection to happen isn't necessarily an issue, but
not allowing it prevents the configured SOCKS proxy from dialing to
private addresses.
This commit lets the watchtower automatically create hidden services
by giving it a pointer to a TorController. The server was also slightly
refactored so that it was not the sole owner of the TorController.
Add an error buffer to the peer struct which will store errors for
peers that we have active channels with. We do not store these errors
with peers that we do not have channels open with to prevent peers from
connecting and costlessly spamming us with error messages. When the peer
disconnects, the error buffer is offloaded to the server so that we can
track errors across connections. When peers reconnect, they are created
with their historic error buffer.
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.
In this commit, we modify the AddOnionConfig struct to include an
abstract OnionStore, which will be responsible for storing all relevant
information of an onion service. We also add a file-based implementation
of the interface to maintain the same behavior of storing an onion
service's private key in a file.
In this commit, a htlcNotifier interface is added to allow for easy
unit testing. Instances of the HtlcNotifier are added to the server,
switch and link.
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 adds PendingOpenChannel to SubscribeChannelEvents stream in
the gRPC API.
This is useful for keeping track of channel openings that Autopilot does.
It can also be used for the non-initator side of a channel opening to keep
track of channel openings.
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.
In this commit, we update the `OpenChannel` method to observe the new
`funding_shim` field in the main open channel request. If this is
specified, and is a channel point shim, then we'll create a custom
`chanfunding.Assembler` for the wallet to use in place of the regular
funding workflow.
With this commit, the "initiator" of an external funding flow can now
delegate the remainder of the channel funding workflow to lnd.
This commit adds InvoiceExpryWatcher which is a separate class that
receives new invoices (and existing ones upon restart) from InvoiceRegistry
and actively watches their expiry. When an invoice is expired
InvoiceExpiryWatcher will call into InvoiceRegistry to cancel the
invoice and by that notify all subscribers about the state change.
This commit adds Clock and DefaultClock and moves the private
invoices.testClock under the clock package while adding basic
unit tests for it.
Clock is an interface currently encapsulating Now() and TickAfter().
It can be added as an external dependency to any class. This way
tests can stub out time.Now() or time.After().
The DefaultClock class simply returns the real time.Now() and
time.After().
