This commit is part of a refactor that unifies configuration of the
sqldb and kvdb packages for SQL backends.
In order to unify the SQLite and Postgres configuration under sqldb we
first need to ensure that the final config types are compatible with
the alreay deployed versions.
This change will enable us to use a single PostgreSQL container instead of
spawning new a one for each (parallel) unit test reducing overall test
runtime.
This commit attempts to fix some issues with the invoice store's schema that we
couldn't foresee before the implementation was finished. This is safe as the
schema has not been instantiated yet outside of unit tests. Furthermore the
commit updates invoice store SQL queries according to fixes in the schema as
well as to prepare the higher level implementation in the upcoming commits.
This commit adds a new sub command to the wallet that allows using the
new funding option from a template.
Creating a new command is way easier for the user to understand than
adding multiple flags that are only valid in certain combinations.
For the itest in the next commit we'll need to be able to fetch the
input information for an address over RPC. The only piece missing is the
address' index, which we add in this commit. Everything else should be
derivable from the ListAddresses and ListAccounts calls.
In some situations (for example in Taproot Assets), we need to be able
to prove that an address is a bare BIP-0086 address that doesn't commit
to any script. We can do that by providing the BIP-0032 derivation info
and internal key.
In this commit, we add two new methods that simplify usage of an
handling a value wrapped in an Option. Thes methods allow a caller to
force the nil/None check up front, and either obtain the value, or fail
the current execution or test.
This should replace most usages of `UnsafeFromSome` where ever used
today.
In the following commits we'll add a new, third, funding option for
funding PSBTs: It will allow users to specify pre-selected inputs but
still request the wallet to perform coin selection up to the total
output sum amount.
This is a helper function that we will need to accurately determine the
weight of inputs specified in a PSBT.
Due to the nature of P2WSH and script-spend P2TR inputs, we can only
accurately estimate their weights if the full witness is already known.
So this helper function rejects inputs that use a script spend path but
don't fully specify the complete witness stack.
We want to re-use the logic that determines what change amount is left
over depending on whether we add or don't add a change output to a
transaction, respecting the change output's dust limit.
We'll want to be able to tell the coin selection algorithm that we
intend to add any change to an existing output instead of assuming that
a change output is always created.
If we add any left over change to an existing output, we can skip the
dust amount check as we assume the selected existing output already has
a non-dust amount requested (responsibility of the caller to assert).
Before this commit the coin selection logic in the chanfunding package
would always assume that there is a P2WSH funding output and potentially
a P2TR change output. But because we want to re-use the coin selection
for things other than just channel funding, we make the logic more
generic by allowing us to specify both the existing weight of the
transaction (the already known, static parts of the TX) as well as the
type of the potential change output we would use.
With this commit we prepare for the lnwallet channel funding logic to be
aware of the config-level coin selection strategy by adding it to the
wallet config.
In this commit, we start persisting shutdown info when we send the
Shutdown message. When starting up a link, we also first check if we
have previously persisted Shutdown info and if we have, we start the
link in shutdown mode meaning that it will not accept any new outgoing
HTLC additions and it will queue the shutdown message after any pending
CommitSig has been sent.
In this commit, we add the ability to start a link in shutdown mode.
This means that we immediately disable any new HTLC adds in the outgoing
direction and that we queue up a Shutdown message after the next
CommitSig message is sent (or immediately if no CommitSig message is
owed).
ShutdownInfo contains any info about a previous Shutdown message that we
have sent. This commit adds this type along with read and write methods
for it in the channel db. The existence of the ShutdownInfo on disk
represents the fact that we have previously sent the Shutdown message
and hence that we should resend it on re-establish.
This commit adds an itest to demonstrate that the following bug exists:
If channel Shutdown is initiated but then a re-connect is done before
the shutdown is complete, then the initiating node currently does not
properly resend the Shutdown message as required by the spec. This will
be fixed in an upcoming commit.
