This commit includes some slight refactoring to properly execute force
closures which are initiated by RPC clients.
The CloseLink method within the htlcSwitch has been extended to take an
additional parameter which indicates if the link should be closed
forcefully. If so, then the channelManager which dispatches the request
executes a force closure using the target channel state machine. Once
the closing transaction has been broadcast, the summary is sent to the
utxoNursery so the outputs can be swept once they’re mature.

`lncli showroutingtable` may output routing table as image.
Use graphviz for graph rendering.
Add explicit version dependency for tools. Add error checking.
LIGHT-133, LIGHT-138 Make output of `lncli showrouting table` in
two different formats: table and json.
Instead of sending serialized routing table send list of channels.
This commit adds a new feature to the network harness enabling callers
to receive async notifications once a particular transaction is seen on
the network. Such a feature is useful when due to the asynchronous
behavior of node communications.
With this new feature, tests can now wait for a particular transaction
to be seen within the network before proceeding.
This commit modifies the internal workflow for opening or closing a
channel in order to create a path in which RPC clients can receive
updates. Updates are now communicated via channels from the goroutines
spawned by the RPC server to process the request, and the sub-system
within the daemon that actually executes the request.
With this change clients can now receive updates that the request is
pending (final message has been sent to the target client), or that the
request has been completed. Confirmation related updates have not yet
been implemented as that will require some changes to the ChainNotifier
interface.
This commit integrates BitFury's current routing functionality into lnd. The
primary ochestration point for the routing sub-system in the routingMgr. The
routingMgr manages all persistent and volatile state related to routing within
the network.
Newly opened channels, either when the initiator or responder are inserted into
the routing table once the channel is fully open. Once new links are inserted
the routingMgr can then perform path selection in order to locate an "optimal"
path to a target destination.
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.
This commit implements the “pendingchannels” RPC within the rpcserver.
This RPC allows callers to receive details concerning the current
pending channels associated with the daemon. Pending channels are those
waiting for additional confirmations before they can be considered
opened/closed.
At the time of this commit, only open channels are shown. A future
commit will also add the confirmation updates, along with information
for close channels.
This commit switches the implementation of the open/close channel RPC’s
from a fully blocking synchronous model to one that’s async by default,
allowing callers to add a sync wrapper.
The new proto specs also allow for “updates” for the pending channels
in the form of new confirmations which progress the pending status of
the channel. At this point, only the final open/close updates have been
implemented. Obtaining confirmation notifications requires a bit of
re-working within the current ChainNotifier interface, thus this has
been deferred to a later time.
This commit implements the “send coins” RPC request which was
introduced at both the lnrpc and command line level in a prior commit.
A small refactoring has taken place w.r.t to sendmany+sendcoins in
order to eliminate some code duplication.
This commit fixes a bug introduced within a prior commit. The prior
commit failed to drollery reverse the txid string taken in as user
input, therefore in order to properly close a channel, the user needed
to manually reverse the txid themselves.
With this change, `wire.NewShaHashFromStr` is used which properly
reverses the string within the constructor. This allows the string
reported not be directly used to the close an active channel.
This commit also corrects a few logging messages.
This commit adds the necessary plumbing within the server, peer, and
rpcServer to handle opening and cooperatively closing a channel with a
remote peer.
Many new data structures have been added to the peer in order to allow
it to efficiently manage opening+.losing new/existing lightning
channels. Additional documentation has been added to several methods
within the peer struct, with some minor renaming along with way. The
peer has also gained a dedicated goroutine whose job it is to manage
any requests pertaining to opening, or closing any channels with the
remote peer.
The messages have been added to lnrpc define the requests and responses
to channel open+close messages. Additional channel logic has been added
between the rpcServer, peer, and server in order to properly manage the
necessary synchronization.
The new available address types are: regular p2pkh, p2wkh, and finally
p2wkh nested within p2sh. The latter address type will initially be
used to allow users to “fund” the lnd wallet.
