If a forceClose happens and the to-self output is below the dust value,
then that output will be non-existant in the commitment transaction.
UtxoNursery now handles that case by checking to see if the accompanying
selfOutPutSignDescriptor is nil. If it is nil, then it will ignore it.
If the value of the to-local output is below the dust limit, the
ForceCloseSummary should not include a sign descriptor for this output.
We also find the proper to-self output by looking for the expected public
key script and not assume that no HTLC outputs exist.
Currently non-HTLC outputs will be accepted in the commitment
transaction as long as it is non-zero. We change this by not allowing
outputs with a value lower than the dust limit. The value of such
an output will go towards transaction fees.
This commit modifies the glide target for btcwallet to pin against a
particular commit that will attempt to auto-reconnect to the btcd node
in the case of a websockets connection drop.
This commit adds a new field to the ListChannels RPC command which
indicates if the peer is currently online or not. This is useful as
UI’s will be able to use this information to communicate the
availability of each channel to an end user.
This commit adds some new functionality to the channel router: the
ability to dispatch notification to registered clients upon either a
channel being closed, a new node appearing, or an exiting client being
updated or opened for the first time.
With this change, the integration tests will now be able to eliminate
most of the sleep as we gain a new syntonization point into the
propagation of information within the test network. Additionally, this
also paves the way for client side software to dynamically visualize
the channel graph in real-time as nodes+channels are updated.
This commit modifies the path finding routines to properly use the new
channel edge related API exposed by the database. Additionally, a new
type `ChannelHop` has been introduced which couples an edges routing
policy with the capacity and origin chain of the channel.
This commit modifies the ChannelUpdateAnnouncement to rename the Expiry
variable instead of TimeLockDelta as that is more descriptive of the
purpose of the attribute itself.
This commit updates all the RPC’s that deal with querying for data
stored within the graph to the latest version of the public API for the
graph itself.
This commit alters the return value of PrunedGraph to me a bit more
useful: the function now returns all the channels that were closed when
processing the block (slice of spent outpoints). With this information,
callers gain greater visibility into exactly which channels were
closed. This can be used in higher levels to present detailed summaries
of how blocks affect closed channels.
This commit splits the prior ChannelEdge struct into two distinct
structs: ChannelEdgeInfo and ChannelEdgePolicy. The info structs stores
the _full_ information that was used to advertise the channel, while
the policy struct contains the information that’s needed in order to
use the information for routing purposes.
With this split we can eliminate a number of hacks within the rest of
the codebase that were added as a result of data unavailability if one
or neither edge was present.
Finally a bit of field renaming has taken place (Exipiry ->
TimeLockDelta), etc.
This commit fixes a minor bug that was introduced with the latest PR
that made specifying the —push_amt flag when opening a channel
mandatory. The fix is simple, turn the switch statement into an
if/else, which makes the —push_amt flag optional once again.
This commit updates the command line help for several commands within
cmd/lncli to be more uniform, and also use the proper attributes within
the urfave/cli project. Additionally, in several areas cli.Int was using
used instead of cli.Int64 when parsing satoshis. This oversight has been
rectified by modifying all incorrect occurrences.
Finally, this commit, as its central contribution, adds the ability to mix
and match positional arguments with key-word arguments for several
commands! The following commands can now be used with either only
positional arguments, only key-word arguments, or a mix of both when
applicable:
* openchannel
* closechannel
* sendpayment
* getnodeinfo
* getchaninfo
* newaddress
* sendcoins
* sendmany
* connect
* addinvoice
* lookupinvoice
* queryroute
The set of changes outlined above should make command line tinkering with
`lnd` a bit more streamlined, yet still very flexible.
This commit adds a basic set of instructions for installing the necessary
gRPC dependencies to be able to drive `lnd` from node.js. In the future,
this section will be expanded with additional example
scripts/applications.

This commit modifies the `ecdh` function within the `brontide` package
to refer directly to the global curve params object in the `bcec`
package rather than reference it from the target public key. This
changes fixes a class of panics that have been uncovered recently but
*doesn’t* yet fix the root cause.
This commit modifies the protobuf file and most of the auto-generated
files to be generated by protoc version v3.0.2. Additionally, this
fixes a minor cosmetic regression within the `lncli` command line tool
which caused the JSON responses to be rendered in `camelCase` rather
than `snake_case`. We fix this by specifying the `json_name` for each
relevant RPC response.
This commit fixes a class of bug that currently exists within the
cooperative closure methods for the channel state machine. As an
example, due to the current hard coded fees, if one of the outputs
generated within the generated closure transaction has a negative
output, then the initiating node would gladly forward this to the
remote node. The remote node would then reject the closure as the
transaction is invalid. However, the act of completing the closure
would cause the remote node’s state machine to shift into a “closed”
state. As a result, any further closure attempts by the first node
(force or regular) would go unnoticed by the remote node.
We fix this issue by ensuring the transaction is “sane” before
initiating of completing a cooperative channel closure.
At test case has been added exercising the particular erroneous case
reported by “moli” on IRC.
This commit avoids a class of bug wherein the state of the channel
would be marked as closing enough though an error occurred somewhere in
the function. The bug was due to the fact that the channel `status` was
shifted before any actual logic within the function(s) were executed.
We fix this bug by _only_ shifting the channel status once the function
has completed without any error.
This commit fixes a bug that resulted from properly failing to do a
2-value read from the confirmation notification channel. If the
ChainNotifier was shutting down, then a nil read could be generated
which may prematurely mark the channel as open, and also trigger a nil
pointer panic exception below when the confDetails are accessed.
We fix this issue, by ensuring that we check the second value to see if
the channel has been closed or not.
This commit modifies the peer struct’s loadActiveChannels method to
ensure that it skips over channels that aren’t actually active. This
fixes a bug that could possibly cause a peer to get stuck in a circular
wait loop and also de-sync a channel’s state machine.
This commit renames routing processing method in the funding mangers
config from ProcessRoutingMessage to SendToRouter and also modifies the
signature to only require the message itself and not the server’s
identity public key.
With the funding manager’s state gaining full durability, it only will
return channels that are currently “pending” as a response to the
PendingChannels RPC call. As a result, the prior edge case where a user
would issue a PendingChannels RPC call mid funding flow is no longer
possible and channels are read from disk rather then from the
fundingMgr’s limbo state.
With the concept of open/pending channels on disk, we now will no
longer show channels under ListChannels that are still pending. This
fixes a slight existing bug wherein channels that weren’t yet open
would be listed in this RPC call since we write to disk immediately
after broadcasting the funding transaction.
