This commit modifies the GetUtxo method of the BlockChainIO interface
to be more light client friendly by introducing a height hint which
gives light clients that don’t have UTXO set commitments a way in which
they can restrict their search space. Light clients will now be able to
have a concrete cut off point in the chain as they scan backwards for
spentness of an output.
This commit introduces a new method to the ChannelGraph struct:
ChannelView. This struct returns all the outpoints that represent the
set of active channels within the network. The set of items returned by
this new method will possibly shrink with each call to `PruneGraph`,
and possibly be expanded by each call to `AddChannelEdge`.
The graph pruning tests have been updated to ensure the description
above holds true.
This commit adds simple non-blocking stop command to lncli, with an
appropriate proto update and implementation within the rpcserver. When
invoked the interrupt handler routine in signal.go with begin the graceful
shutdown of lnd.
In this commit waiting proofs array have been replaced with persistant
boltd storage which removes the possibility for the half proof to be
lost during half proof exchange.
This commit modifies the implementation of the new DisconnectPeer RPC
in the following ways:
* all validation has moved from the server to the rpcserver
* rather than iterating over _all_ channels, we now only check the
peer’s channels
* the disconnectPeerMsg now has a public key object
* this allows us to also verify that the user submitted a valid
pub key string
* we now check if a peer was persistent when disconnecting so we can
remove them from the persistent peer map
This commit fixes a prior bug wherein if a user connected to a peer
using the —perm command, then once the peer was disconnected, we
wouldn’t automatically connect to them.
This commit fixes a race condition that was uncovered by the race
condition detector surrounding cancelling active block epoch
notifications. Previously we would close the main notification channel
for each client, at tine this would cause a read/write race condition
if an active grouting was attempting to dispatch a notification. We now
fix this use by using a distinct channel for signaling cancellation to
the active grouting, and another to signal cancellation to any
notification observers.

This commit contains test case "disconnecting target peer" (second test case) which takes two
connected peers, then checks via assert method one connection exists,
then disconnects this remote peer by passing pubKey parameter (just some string) into RPC-call method. Then checks 0
connection exists, and then connects disconnected peer for passing
further tests, and then checks one connection exists.
Issue: 139
This commit contains client-side and server-side functionality
for disconnecting peers. rpc-client calls server side method and sends
message with pubKey.
This commit fixes a bug that was introduced when the concurrent
connection handling logic was re-written: if we don’t properly add the
persistent outbound connection to the persistent conn reqs map. The fix
is easy: add the pending conn req to the proper map.
This commit adds a start up check to the breachArbiter: it will now
watch all channels which are in the “pending closed” state, to ensure
that state of the database is up to date at all times. Once any of the
closing transactions for these channels have been confirmed, then they
will properly be marked as such within the database.
This commit modifies the breachArbiter to properly mark a channel as
_fully_ closed once the transaction which force closed the channel has
been confirmed within the chain.
Within this commit the peer will now properly manage the channel close
life cycle within the database. This entails marking the channel as
pending closed either once the closing transaction has been broadcast
or the close request message has been sent to the other side.
Once the closing transaction has been confirmed, the transaction will
be marked as fully closed within the database. A helper function has
been added to factor out “waiting for a transaction to confirm” when
handling moth local and remote cooperative closure flows.
Finally, we no longer delete the channel state within wipeChannel as
this will now be managed distinctly by callers.
This commit fixes a bug that double counts the number of pending
channels in GetInfo. Previously we weren’t yet storing the pending
channels on disk, we are now but comparing both the disk channel and
the channels within memory leads us to double count channels. To fix
this, we now only count the database channels.
Note that this NumPendingChannels method can now be removed as it’s no
longer needed.
This commit adds a new public facing method to the utxoNursery:
NurseryReport. This method is intended to be used by callers to
introspect into the current state of the utxo nursery. With this
information, callers will be able to ascertain: the number of immature
outputs, the total number of funds in limbo, and when funds can be
fully swept.
This commit adds to new index buckets to the undo nursery: one that
allows searching the preschool bucket by origin chan point, and another
that allows querying the kindergarten bucket using an identical key.
These index buckets are updated in tandem with their regular buckets.
A note has been named in this commit to re-work the bucket structure
for a time in the near future in which we have implemented full
on-chain HTLC handling.
This commit adds an additional field to the kidOutput struct: the
outpoint of the channel that originally created the output. This field
is now needed in order to add some additional indexes that are required
to enable callers to query the internal state of the utxoNursery.
This commit modifies the actions of the closeObserver goroutine to
utilize a _new_ channel to send channel close details over. The
original close signal channel is still used to notify observers that a
channel _has_ been closed, but this new channel will provide a single
observer with details w.r.t _how_ a channel was closed.
This commit adds an additional field to the ForceCloseSummary that
allows observers of the channel that sends this struct to track _which_
channel the force close came from.
This commit adds some additional fields to the PendingChannels RPC s.t
users will be able to use the RPC to gain a complete view w.r.t where
all the funds within the daemon are, and how soon they can be
retrieved.
The following information is now returned:
* all channels pending open
* all channels pending cooperative close
* all channels pending force close
This commit fixes a bug that would possibly result in tens of goroutine
beaching launched in an attempt to persistently connect to a peer. This
bug has been fixed by ensuring that we’ll only launch a new pending
connection attempt if we don’t already have one pending.
This commit adds a new method to the database which allows callers to
mark a channel as fully closed once certain conditions have been
reached. If a channel was cooperatively closed, then it can be marked
as fully closed as soon as the channel has been confirmed. If the
channel was marked as force closed, then it should be marked as closed
as soon as _all_ the funds in limbo have been swept.
This commit builds upon the prior commit by adding a new method to
allows callers to query the state of all closed (fully) and pending
closed channel within the database.
This commit expands the close summaries within the database to include
additional information such as: how the channel was closed, if the
channel if fully closed, and other balance information. This new
information will be used in an upcoming expansion of the
pendingChannels RPC to display more comprehensive data w.r.t where the
node’s funds are and how soon they’ll be fully available.
The data stored in the closeChannel bucket has been expanded to include
the above. Additionally the CloseChannel method on the OpenChannel
struct now takes in the additional information that details how and who
it was closed by.
This commit borrows heavily from the initial work in #179 by @halseth.
