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.
This PR moves any address notifications outside of the
db transaction that creates them. This is known to have
resulted in deadlocks, since chainClient.NotifyReceived
could block the db transaction from committing.
Doing so also prevents the situation where we send
notifications about the new addresses, but the db txn
fails to commit and the addresses are in fact never
created.
This commit places a mutex around calls to newSecretKey,
since the inner function needs to be swapped out
during testing. Prior to this change, the race
detector would panic since the mutation was
unprotected.
This commit adds rescanWithTarget, in order to facilitate
rescans beginning a certain height. This is done as a
precursor to fixing a bug in the initial sync, that would
cause us to miss relevant txns if they are confirmed before
starting the initial rescan.
In this commit, we remove the duplicate test case from TestStoreQueries
as we'll no longer allow storing a transaction as unconfirmed if it's
already confirmed.
In this commit, we resolve a lingering bug within the wallet where it's
possible that an output is added as unconfirmed credit after the fact
that it has already confirmed. This would lead to duplicate entries for
the same output within the wallet causing double spend transactions to
be crafted.
In this commit, we add a new test case to the wtxmgr store to ensure
that duplicate outputs don't exists within the store. It's possible for
this to happen if an output is marked as unconfirmed credit, then marked
as confirmed once it confirms, and once again marked as unconfirmed. It
can be marked as unconfirmed again due to the backend notifying the
client about this transaction. Ideally this should not happen, but the
root cause is much more involved. As a stop gap, we'll ensure that
outputs can be marked as unconfirmed credits more than once whatsoever.
As is, the test case fails, which proves that this is an issue. A later
commit will resolve this and the test case should pass.
In this commit, we remove the keep-alive logic within the handler of the
RPCClient struct as this logic already exists within the backing
rpclient.Client instance. In this case, we'd completely stop the
connection after the ping timeout (1 min), which would render the
reconnection logic within rpcclient.Client useless.
In this commit, we fix a small issue where it's possible that we read a
malformed message from the ZMQ connection to bitcoind due to it shutting
down. To fix this, we ensure that the event type is human readable
before attempting to log it.
