In this commit, we add a new key/value pair within the waddrmgr's
syncBucket that will represent the birthday block of the wallet. This
can then be used to force rescans from this point, rather than from the
genesis block.
In this commit, we convert our unit tests to have package-level access.
We do this as an effort to reduce test code duplication when we
introduce migration tests which require access to specific unexported
functions/methods.
ImportPrivateKey
In this commit, we ensure that when an external private key is imported
into the wallet, that we do not overwrite our existing birthday with the
one provided. If this were to happen and we forced a wallet rescan using
the birthday as our starting point, then we'd miss detecting relevant
on-chain events that occurred between them.
In this commit, we remove the old upgrade/migration logic of the address
manager as it's been superseded by the new approach using the
migration.Manager interface.
In this commit, we remove the old upgrade/migration logic of the
transaction manager as it's been superseded by the new approach using
the migration.Manager interface.
In this commit, we modify the wallet to use the new migration logic
provided by the recently introduced migration package. Additionally,
we'll also perform all of our upgrades within the same database
transaction to guarantee fault-tolerance of the wallet.
In this commit, we can remove the LatestVersion constant as it's no
longer needed. Instead, we'll now define the latest version as the last
entry in the slice of versions previously defined.
In this commit, we add an implementation of the recently introduced
migration.Manager interface for the transaction manager. With this,
we'll now be able to only expose the things required for the migration
to happen, but have the actual migration logic live at a much higher
level.
There are no existing migrations for the transaction manager, but since
the latest version was already defined as 1, we'll start from there to
be backwards-compatible.

In this commit, we add an implementation of the recently introduced

The existing versions defined are set up in the same way as the existing
upgrade/migration logic, which will end up being superseded by this and
removed in a later commit.
In this commit, we add a new sub-package to the walletdb package:
migration. In this package, we define a new interface, Manager, which
will expose all of the necessary functions required to abstract the
migration logic of different sub-services within the wallet, like the
address and transaction managers. The implementations of this interface
will then be able to use the migration logic within the Upgrade
function with no additional complexity.
In this commit, we relax the initial sync detection logic a bit. We do
this as right now, if a user creates an address during the sync point,
if they restart, then we'll fall back to performing a rescan from that
height as we'll detect that we aren't performing the initial sync, so
won't pick up the birthday timestamp.
To fix this, we now declare that if we have no UTXO's, then we're still
performing the initial sync. This solves this issue as when the user
restarts, we'll continue to wait for the backend to sync, and pick up
the proper birthday height before we attempt to scan forward for the
rescan. However, the one tradeoff is that we'll now always start the
rescan from the birthday height until the wallet has gained it's first
UTXO. I don't think this is too bad, as after all, the point of a wallet
is to manage utxos.
In this commit, we extend TestRemoveUnminedTx to also account for
checking the store's total balance (confirmed and unconfirmed). It
currently ensures that the UTXO state is correct, but as a sanity check,
we'll also ensure that balances are properly updated.
In this commit, we refactor the logic outside of PublishTransaction into
another unexported method. This will pave the road for unifying the
logic between SendOutputs and PublishTransaction.
In this commit, we simplify the logic when broadcasting transactions to
the greater network. Rather than special casing when running with a
Neutrino backend, we'll always add the transaction to the store as
relevant when attempting to broadcast it. This will properly insert it
into the store and update unconfirmed balances. In the event that the
transaction failed to broadcast, it can be removed from the store with
no side-effects, essentially acting as if the transaction was never
added to the store in the first place.
In this commit, we modify the SendOutputs method to also notify new
outgoing transctions for neutriino. For the full node backends, they'll
get this notification when the transactino hits the mempool. However,
for neutrino it will only be notified once the transaction has been
confirmed. This commit ensures that we'll notify on send as well.
In this commit, we avoid notifying clients of transactions that we've
received chain.RelevantTx notifications for, but are not found within
the wallet. This can happen as now we'll prevent adding an unconfirmed
transaction to the wallet that already exists as confirmed. Due to this,
UniqueTxDetails will be unable to find the transaction and return nil,
casuing a panic for potential callers.
