The field is optional. It stores inputs needed to produce signed commit tx using
chantools scbforceclose, which calls function GetSignedCommitTx. New backups
have this field filled if commit tx is available (for all cases except when DLP
is active). If a backup has this data, the field is filled from it, otherwise it
is kept empty.
Modified test function genRandomOpenChannelShell to cover new types of channels
(simple taproot channel and custom channel) and to cover combinations of bits.
Make sure that TapscriptRoot field is properly packed and unpacked.
This commit was previously split into the following parts to ease
review:
- 2d746f68: replace imports
- 4008f0fd: use ecdsa.Signature
- 849e33d1: remove btcec.S256()
- b8f6ebbd: use v2 library correctly
- fa80bca9: bump go modules
As a preparation to have the method for querying the addresses of a node
separate from the channel state, we extract that method out into its own
interface.
Adds an optional tx parameter to ForAllOutgoingChannels and FetchChannel
so that data can be queried within the context of an existing database
transaction.
In this commit, we introduce a series of interfaces and methods that
will allow external callers to backup either all channels, or a specific
channel identified by its channel point. In order to abstract away the
details w.r.t _how_ we obtain the set of open channels, or their storage
mechanisms, we introduce a new LiveChannelSource interfaces. This
interfaces allows us to fetch all channels, a channel by its channel
point, and also all the known addresses for a node as we'll need this in
order to connect out to the node in the case of a recovery attempt.
