Migrate all btcd dependencies to the new per-package v2 modules (wire/v2,
txscript/v2, chaincfg/v2, chainhash/v2, btcutil/v2, psbt/v2, btcec/v2)
introduced by btcd v0.26.0, and pin the tagged ecosystem versions:
btcwallet v0.17.0, neutrino v0.18.0 and lightning-onion v1.4.0.
The bulk of the import rewrite was produced by the scripted diff from
https://github.com/btcsuite/btcd/pull/2547 (followed by 'make rpc'). The
address symbols that moved out of btcutil into the new address package
are imported as btcaddr where a local "address" variable would otherwise
shadow them. The go.mod/go.sum updates and the remaining manual
compilation fixes are folded into this single commit so it builds on its
own (the migration was previously split into a reproducible scripted-diff
plus follow-ups, intended to be squashed on merge).
This commit extends the taproot HTLC script generation functions to accept
TaprootScriptOpt parameters, enabling callers to specify whether production
or staging script variants should be generated. The SenderHTLCScriptTaproot
and ReceiverHTLCScriptTaproot functions now accept a variadic opts parameter
that is forwarded to the underlying script tree construction.
This change provides the necessary infrastructure for the wallet and contract
resolution systems to generate the appropriate script trees based on channel
type. Production taproot channels can now pass the WithProdScripts() option
to generate optimized scripts using OP_CHECKSIGVERIFY, while staging channels
continue to use the existing development script structure.
The modification maintains backward compatibility by making the opts parameter
variadic with sensible defaults. Existing callers that do not specify options
will continue to generate staging scripts as before, ensuring no disruption
to current functionality while enabling future production script support.
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
The new commitment type consists of adding an additional CLTV
requirement to guarantee a leased channel's expiration on any commitment
and HTLC outputs that pay directly to the channel initiator.
This commit introduces the Signature interface which will be used by our
witness construction methods instead of passing in raw byte slices. This
will be used later to inject various kinds of mock signatures, e.g.
73-byte signatures for simulating worst-case witness weight.
We also increase the witness size for these types to account for the 3
extra bytes. The size won't be correct in all cases, but it is just an
upper bound in any case.
To be able to change more than the witness used for each test case, we
extract commit and sweep tx generation into own methods that can be
called from each test case.
We do the same for TestHTLCReceiverSpendValidation
This fixes an error case that wouldn't have been caught, since
vm.Execute applies more rules than the individual steps (most notably
the clean stack rule).
Instead we execute the engine as normal, and only step through if we
decide that the outcome is unexpected.
This commit is a step to split the lnwallet package. It puts the Input
interface and implementations in a separate package along with all their
dependencies from lnwallet.
