Add the TrueBoolean type along with its Record method. Also update the
Millisatoshi type with a Record method. Both of these will be used in an
upcoming commit which adjusts a mission control migration to use pure
TLV types.
Add new FirstBlockHeight and BlockRange TLV fields to the
GossipTimestampRange message. This will be used to query for Gossip 1.75
messages which are timestamped using block height instead of Unix
timestamps.
In preparation for Gossip 1.75, we add new TLV's to the `ChannelReady`
message. Namely: `AnnouncementBitcoinNonce` and `AnnouncementNodeNonce`.
These will be used to exchange nones required for producing the partial
signature to be send in the `AnnouncementSignatures2` message.
The type numbers for these new fields are even because if they are set,
then a peer is expecting its peer to understand gossip 1.75 and the new
fields.
In preparation for adding the new ChannelAnnouncement2 message along
with a ChannelAnnouncement interface, we rename the existing message to
ChannelAnnouncement1.
In preparation for adding a new message, AnnounceSignatures2 along with
an AnnounceSignatures interface, we rename the existing message to
AnnounceSignatures1.
Currently if an incorrect number of timestamps is given, we fail later
on in the GossipSyncer. It makes more sense to fail right away, since we
already do that for incorrect SCID formats (e.g., unsorted or duplicate
SCIDs). There is already a matching check in Encode for incorrect number
of timestamps, so adding this check to Decode makes things symmetric.
- Introduce the field `CustomRecords` to the type `UpdateFulfillHtlc`.
- Encode and decode the new field into the `ExtraData` field of the
`update_fulfill_htlc` wire message.
- Empty `ExtraData` field is set to `nil`.
- Introduce the field `CustomRecords` to the type `UpdateAddHtlc`.
- Encode and decode the new field into the `ExtraData` field of
the `update_add_htlc` wire message.
This commit introduces the `CustomRecords` type in the `lnwire` package,
designed to hold arbitrary byte slices. Each entry in this map can
associate with TLV type values that are greater than or equal to 65536.
We need a new feature bit for BOLT11 invoices in order to indicate that
they contain the new blinded path tagged field. Tagged fields pre-date
TLV and so nodes who dont understand them will simply skip them.
Therefore the feature bit helps them to fail fast.
In this commit, the tlv extension of a channel update message is parsed.
If an inbound fee schedule is encountered, it is reported in the
graph rpc calls.
This commit adds an optional blinding point to payment descriptors and
persists them in our HTLC's extra data. A get/set pattern is used to
populate the ExtraData on our disk representation of the HTLC so that
callers do not need to worry about the underlying storage detail.
Add blinding points to update_add_htlc. This TLV will be set for
nodes that are relaying payments in blinded routes that are _not_
the introduction node.
This commit adds encoding and decoding for blinded route data blobs.
TLV fields such as path_id (which are only used for the final hop)
are omitted to minimize the change size.
We'll need to pack feature vectors for route blinding, so we pull
the encoding/decoding out into separate functions (currently
contained in ChannelType). Though it's more lines of code, we keep
most of the ChannelType assertions so that we strictly enforce
use of the alias.
The purpose of this interface is to distinguish messages that are
bound to a particular channel_id from those that are not. There is
no reason this ought to be a property of the peer package as it is
entirely determined by the contents of the message itself. Therefore
we move it to the lnwire package so it can be used without having
import cycles elsewhere in the codebase.
In this commit, we update new Taproot related TLVs (nonces, partial sig,
sig with nonce, etc). Along the way we were able to get rid of some
boiler plate, but most importantly, we're able to better protect against
API misuse (using a nonce that isn't initialized, etc) with the new
options API. In some areas this introduces a bit of extra boiler plate,
and where applicable I used some new helper functions to help cut down
on the noise.
Note to reviewers: this is done as a single commit, as changing the API
breaks all callers, so if we want things to compile it needs to be in a
wumbo commit.
