This commit alters the configuration parsing a bit along with the
documentation to expect the RPCHost configuration paramter to also have
the target port specified. If the port isn’t included, then the default
btcd RPC port for that chain is used.
Additionally, within the integration testing framework, when creating
the lnd nodes, we now use the configuration from the btcd harness to
set the proper RPC host.
This commit revamps the way in bound and outbound connections are
handled within lnd. Instead of manually managing listening goroutines
and also outbound connections, all the duty is now assigned to the
connmgr, a new btcsuite package.
The connmgr now handles accepting inbound (brontide) connections and
communicates with the server to hand off new connections via a
callback. Additionally, any outbound connection attempt is now made
persistent by default, with the assumption that (for right now),
connections are only to be made to peers we wish to make connections
to. Finally, on start-up we now attempt to connection to all/any of our
direct channel counter parties in order to promote the availability of
our channels to the daemon itself and any RPC users.
This commit adds a new configuration parameter to the deamon:
‘DebugHTLC’. When true, all outgoing HTLC’s sent via the RPC interface
will be sent paying to a special rHash value which all lnd nodes also
with the flag activated know the preimage to. Therefore all payments
sent to a 1-hop node will immediately be settled by that node.
By default, this flag is false, it it only intended to be used to
exercise local changes to 1-hop behavior manually.
This commit adds an option to pass in a raw hex-encoded rpc cert via
lnd’s configuration file. Such a change allows for programmatically
creating lnd nodes which can connect to an existing btcd instance
without requiring a file for the rpc cert to be specified.
Additionally, this commit makes the creation of an integration testing
harness easier.
With this commit, support for changing the target network (testnet,
simnet, etc) has been finalized. Previously a command line option was
present to swap networks, but the RPC port wouldn’t automatically be
updated to reflect the network.
