This commit fixes a race condition that was discovered as a result of
the new htlcswitch package. The StateSnapshot method and all of the
other methods which mutate the state of the channel state machine were
using distinct mutexes. The fix is trivial: all methods accessing the
internal channel state variable now use the same mutex.
This commit optimizes the neutrino implementation of FilterBlock method
of the ChainView interface. The old implementation would _always_ fetch
the entire block and manually scan through it. Instead, we can just
fetch the filter, and then if the items match, fetch the block itself.
This will save bandwidth during a lnd node’s pruning of the channel
graph after a period of dormancy.
This commit fixes a bug wherein the wallet would use the default relay
fee to craft transactions. On testnet, this might be insufficient or be
rejected all together in a mainnet setting. Therefore, we now pass in
the FeeEstimator interface and ensure that it’s consulted in order to
set the relay fee the wallet will use to craft transactions.
Note that this is a hold over until we have true dynamic fee
calculation within lnd which can then be extended to the internal
wallets.
This commit overhauls the way that lnd is created with the goal of
ensuring the chain backends are fully synced up before the daemon
itself starts. The rpcServer has been slightly decoupled from the
server itself s.t we can start the rpcServer independently of the
server. This is required as we’ll now wait (unless we’re in simnet
mode) for the chain to fully sync up before we even _start_ any of the
server’s goroutines.
This commit expands the field within the OpenChannel struct in order to
start tracking the height that the funding transaction was initially
broadcast. Other sub-systems within lnd can now use this data to give a
more accurate height hint to the ChainNotifier, or to use during the
funding workflow to decide if a channel should be forgotten after it
fails to confirm for N blocks.
This commit modifies the Peers method on the server such that a caller
is able to query this method without the main serger goroutines
started. This is a small component in a larger change which will let us
start the RPC server independently of the server.
This commit finishes up the implementation of newChainControlFromConfig
in order to properly initiate the members of the chainControl struct
when the new light client mode (neutrino). With this lnd is now able to
switch over to either mode with a simple configuration change.
This commit adds a new case and proper initialization for the
NeutrinoNotifier implementation, such that it can be tested in-line
with the other implementations for proper behavior conformity.
Due to a delay when btcd sends invs for new blocks, the timeouts for
several of the tests has been extended in order to give enough time for
propagation of the new block.
This commit adds an initial rough implementation father ChainNotifier
interface for neutrino, our new light client implementation. This
implementation largely borrows from the existing BtcdNotifier
implementation. As a result, a follow up commit will perform two
refactoring in order to further consolidate code.
This commit adds a new implementation of the FilteredChainView
interface. This implementation speaks purely to the p2p network and is
backed by a new experimental light client implementation.
This commit fixes a slight regression in the logic of the switch by
ensuring that the log commitment timer is only start _after_ we receive
a new commitment signature. Otherwise, the ticker will keep ticking and
possibly settle HTLC’s that’ve yet to be locked in, or waste a
signature causing us to be deprived of a revocation which is required
for us to initiate a new state transition.
Additionally, the commit performs a few minor post-merge clean ups.
This commit fixes some issues in the display of the stats logger which
resulted in: stats being printed even though no forwarding activity
took place, and underflow of integers resulting in weird outputs when
forwarding.
This commit also adds some additional comments and renames the main
forwarding goroutine to its former name.
