This commit adds a new error type to the `lnwire` package:
`UnknownMessage`. With this error we can catch the particular case of a
an error during reading that encounters a new or unknown message. When
we encounter this message in the peer’s readHandler, we can now
gracefully handle it by just skipping to the next message rather than
closing out the section entirely.
This puts us a bit closer to the spec, but not exactly as it has an
additional constraint that we can only ignore a new message if it has
an odd type. In a future release, we’ll modify this code to match the
spec as written.
With this commit we now pin the version of lightning-onion we build
against at a particular build on the Sphinx package as the package will
be modified in order to accommodate for future changes in the spec.
This commit fixes a bug introduced by the past attempt to Make Logging
Great Again. Since we unset the curve parameters when reading/writing
the messages, if we have a lingering reference that’s active elsewhere
in the daemon, then we’ll modify that reference. To fix this, we now
explicitly set the Curve parameters in two areas.
A similar commit has been pushed to lightning-onion.
This commit fixes a slight bug in the interaction between the cli
program and the rpcsever itself. With this commit it’s now again
possible to create a channel with a peer that’s identified by its
peerID, instead of only the pubkey.
This commit moves the fetching of active channels from the
contractObserver goroutine up to the Start() method on the
breachArbiter. By doing this, we ensure that the user receives an error
(under the current set up) if the btcd node that lnd is connected to
doesn’t have their txindex enabled.
This commit modifies the closeObserver goroutine to ensure that a close
summary has been inserted into the database before signalling any
observers that a unilateral channel closure was detected. This fixes a
slight bug where a peer would force close a channel, but we wouldn’t
properly detect that and clean up the channel state if had a failed
cooperative channel closure.
This commit modifies the login of sent/recv’d wire messages in trace
mode in order utilize the more detailed, and automatically generated
logging statements using pure spew.Sdump.
In order to avoid the spammy messages due to spew printing the
btcec.S256() curve paramter within wire messages with public keys, we
introduce a new logging function to unset the curve paramter to it
isn’t printed in its entirety. To insure we don’t run into any panics
as a result of a nil pointer defense, we now copy the public keys
during the funding process so we don’t run into a panic due to
modifying a pointer to the same object.
This commit modifies the ListInvoice RPC to also return the encoded
payment request in the response. With this change it’ll be possible to
always obtain the encoded payment for any invoice, rather than only
being able to obtain it directly after the creation of an invoice.
This commit modifies the logic of the closeObserver slightly to not
incorrectly mark the broadcast of the commitment transaction triggered
by a cooperative channel closure as an unprompted broadcast.
This commit fixes a bug in the test data that was uncovered due to the
recent bug fix within the AddChannelEdge method within the ChannelGraph
struct of channeldb.
The storage and assertion of unique channel ID’s wasn’t correct due to
bug in the channeldb which caused the defect in the test data to go
unnoticed.
This commit adds support for pushing funds during the funding process
to the helper method in the integration testing framework.
Additionally, we also modify the simple testBasicChannelFunding test to
also push over an amount in order to test the functionality within the
daemon.
This commit modifies our key rotation slightly to match the test
vectors within the BOLT08 specifications. Before this commit, we were
rotating one message before the rest of the implementers. This
implementation divergence was possibly due to the section of the spec
describing the rotations being a bit ambiguous.
A future PR to the lightning-rfc repo will make the spec more explicit
to avoid situations like this in the future.
This commit modifies the ConnectPeer RPC call and partitions the
behavior of the call into two scenarios: the connection should be
persistent which causes the call to be non-blocking, and the connection
should only attempt to connect once — which causes the call to be
blocking and report any error back to the caller.
As a result, the pendingConnRequest map and the logic around it is no
longer needed.
This commit adds daemon level support for pushing funds as part of the
single funder channel workflow. This new feature allows the user to
open a channel and simultaneously make a channel at the same time which
can improve the UX when setting up a channel for the first time.
This commit removes the remote_funding field from the OpenChannel
message as dual funding channels aren’t yet supported at the wire level
within the spec (although the daemon is able to handle them properly).
In place we now add the ‘push_sat’ field which allows the initiator to
push over a certain amount to the responder as part of the initial
state.
This commit adds support to the wallet’s internal funding workflow for
pushing a certain amount of BTC to the responder’s side for a single
funder workflow as part of the first commitment.
This commit adds a new paramter to the initial channel creation:
‘PushSatoshis’. This new field allows the funder of a channel to push
over a certain amount to the responder as part of the initial channel
state. This ability creates a new streamlined UX of finalizing a
payment as a part of the channel creation.
This commit seems to fix a sporadic error within the integration tests
which would at times cause a panic when a payment as initiated.
This issue was with the way were deleting from the middle of the slice
of unvisited nodes within the graph. Assigning the last element to the
middle would at times cause a panic the last element may be nil. To fix
this, we now manually copy every item over by one, preserving the order
of the slice, and possibly fixing the panic once and for all.
With this commit we have gained a new interaction tests which excursus
all the possible multi-hop error cases aside from:
* sphinx packet corruption
The case can’t be adequately tested with the current integration
testing framework as we can’t arbitrary modify packets en route to
peers within the proto test network. In a future commit, the p2p test
framework whcih has been started by andrew.shvv will be used to ensure
proper handling of this error.
This commit adds a critical capability to the daemon: proper handling
of error cases that occur during the dispatch and forwarding of
multi-hop payments.
The following errors are now properly handled within the daemon:
* unknown payment hash
* unknown destination
* incorrect HTLC amount
* insufficient link capacity
In response to any of these errors, an lnwire.CanceHTLC message will be
back propagated from the spot of the error back to the source of the
payment. In the case of a locally initiated HTLC payment, the error
will be propagated back to the client which initiated the payment.
At this point, proper encrypted error replies as defined within the
spec are not yet implemented and will be fully implemented within a
follow up PR.
