Simplifies context cancellation handling by using context.AfterFunc instead of a
goroutine to wait for context cancellation. This approach avoids the overhead of
a goroutine during the waiting period.
For ctxQuitUnsafe, since g.quit is closed only in the Quit method (which also
cancels all associated contexts), waiting on context cancellation ensures the
same behavior without unnecessary dependency on g.quit.
Added a test to ensure that the Create method does not launch any goroutines.
Removed 'cancel' argument, because it is called only in case the context has
already expired and the only action that cancel function did was cancelling the
context.
If feeurl is not provided and LND is running in bitcoind or btcd mode, use
fee estimator provided by bitcoind or btcd instead of using static fee estimator
(which always returns 50 sats/vbyte).
This enables simulating high feerate environment in regtest and simnet not only
via feeurl, but also by filling mempool with high feerate transactions, which is
closer to what happens in mainnet.
Also skip creating bitcoind or btcd fee estimator, if feeurl is provided. Before
LND logged both "Initializing bitcoind backed fee estimator" and "Using external
fee estimator" if running in bitcoind mode with feeurl provided, but actually
feeurl was used, so this is not a change of behavior.
Previously, the error message had one missing space:
"... either --bitcoin.mainnet, or bitcoin.testnet,bitcoin.simnet, ..."
I added a space after "bitcoin.testnet,".
Previously, "lnd --debuglevel show" complained that bitcoin backend is not
configured:
$ lnd --debuglevel show
failed to load config: ValidateConfig: either --bitcoin.mainnet, or ...
To make it working, the user had to specify --bitcoin.mainnet and configure one
of the backends, e.g. "--bitcoin.node neutrino".
With this fix, the command works without any additional flags.
If the delivery address is P2TR, function InternalKeyForAddr checks its
existance in the wallet to return internal key for it in case it is a custom
taproot channel. It used to return the error returned by wallet.AddressInfo.
The error is now ignored if it is ErrAddressNotFound error. This fixes
"lncli closechannel --delivery_addr <external p2tr address" case.
Previously, LND log used to have such records:
[WRN] PEER: Peer(...): Link=%!v(MISSING) is not active
Now the short channel ID is printed there instead of "%!v(MISSING)".
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.
Previous to this change taproot assets channels and simple taproot channels were
considered the same in the context of chanbackup package, since they stored the
same data. In the following commits we are adding the data needed to produce a
signed commitment transaction from a SCB file and in order to do that we need to
add more fields and a custom channel gets one additional field (TapscriptRoot)
compared to a simple taproot channel. So now we have to distinguish these kinds
of channels in chanbackup package.
See PR https://github.com/lightningnetwork/lnd/pull/8183 for more details.
This pure function creates signed commit transaction, using various
inputs passed as struct TaprootSignedCommitTxInputs and a signer.
This is needed to be able to store the inputs without a signature
in SCB and sign the transaction in chantools scbforceclose.
