With this commit, we allow the `MsgRouter` to be available in the `ImplementationCfg`. With this, programs outside of lnd itself are able to now hook into the message processing flow to direct handle custom messages, and even normal wire messages.
Over time with this, we should be able to significantly reduce the size
of the peer.Brontide struct as we only need all those deps as the peer
needs to recognize and handle each incoming wire message itself.
In this commit, we add a new abstract message router. Over time, the
goal is that this message router replaces the logic we currently have in
the readHandler (the giant switch for each message).
With this new abstraction, can reduce the responsibilities of the
readHandler to *just* reading messages off the wire and handing them off
to the msg router. The readHandler no longer needs to know *where* the
messages should go, or how they should be dispatched.
This will be used in tandem with the new `protofsm` module in an
upcoming PR implementing the new rbf-coop close.
In this commit, we start to thread thru the new aux tap leaf structures to all relevant areas. This includes: commitment outputs, resolution creation, breach handling, and also HTLC scripts.
Given the aux leaf store, and a struct that describes the current commitment, we can obtain the CommitAuxLeaves struct, then use that to derive the aux leaves for the commitment outputs and also HTLCs as well.
When restoring commitments and pay descs from disk, we'll store the aux leaves as custom TLV blobs on disk, then use the aux leaf store to map back to the concrete aux leaves when needed.
In this commit, we add a TLV blob to the PaymentDescriptor struct. We also now thread through this value from the UpdateAddHTLC message to the PaymentDescriptor mapping, and the other way around.
This may be useful for custom channel types that base everything off the index (a global value) rather than the output index (can change with each state).
In this commit, we add a new AuxLeafStore which can be used to dynamically fetch the latest aux leaves for a given state. This is useful for custom channel types that will store some extra information in the form of a custom blob, then will use that information to derive the new leaf tapscript leaves that may be attached to reach state.
In this commit, we also add the custom TLV blob to the internal commitment struct that we use within the in-memory commitment linked list.
This'll be useful to ensure that we're tracking the current blob for our in memory commitment for when we need to write it to disk.
In this commit, for each channel, we'll now start to store an optional custom blob. This can be used to store extra information for custom channels in an opauqe manner.
This type is useful when one wants to encode an integer as an underlying BigSize record. It wraps any integer, then handles the transformation into and out of the BigSize encoding on disk.
In this commit, we add a new type alias for a blob type. This type can be used in areas where a byte slice is used to store a TLV value, which may be a fully opaque nested TLV.
We also commit our go.work file to ensure the changes that follow can always build.
In this commit, we update all the taproot scripts to also accept an
optional aux leaf. This aux leaf can be used to add more redemption
paths for advanced channels, or just as an extra commitment space.
With this commit, the channel is now aware of if it's a musig2 channel, that also has a tapscript root. We'll need to always pass in the tapscript root each time we: make the funding output, sign a new state, and also verify a new state.
This isn't hooked up yet to the funding manager, but with this commit, we can now start to write internal unit tests that handle musig2 channels with a tapscript root.
In this commit, we consolidate the root bucket TLVs into a new struct.
This makes it easier to see all the new TLV fields at a glance. We also
convert TLV usage to use the new type param based APis.
In this commit, we rename the files as assembler.go houses the primary
interfaces/abstractions of the package. In the rest of the codebase,
this file is near uniformly called interface.go, so we rename the file
to make the repo more digestible at a scan.
This commit changes how we transform from a deadline option to a
concrete deadline value - previously this is done when we decide to
cluster inputs, and we now move it to a step earlier - once an input is
received via `SweeperInput`, we will immediately transform its optional
deadline into a real value. For inputs that come with a deadline option,
since the Some will be used, it makes no difference. For inputs with
None as their deadlines, we need this change to make sure the default
deadlines are assigned accurately.
This commit adds a test case to check the no deadline sweeping behavior.
The sweeper is updated to make sure it can handle the case for neutrino
backend.
