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 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.
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.
In this commit, ensure that upon restart, if any of the full-node based
backends we support reject the transaction, then we'll properly remove
the now invalid transaction from the tx store. Before this commit, we
could miss a few errors from bitcoind. To remedy this, we explicitly
catch those errors, but then also attempt to precisely catch the set of
generic json RPC errors that can be returned.
In this commit, we fix a bug introduced in an earlier commit. Before
this commit, we would *always* remove an unmined transaction if it
failed to be accepted by the network upon restart. Instead, we should
only remove transaction that are actually due to us trying to spend an
output that’s already spent, or an orphan transaction.
In this commit, we extend the PublishTransction method to be a more
general semi reliable transaction broadcast mechanism. We do this by
removing the special casing for neutrino. With this change, we’ll
_always_ write any transactions to be broadcast to disk. A side effect
of this, is that if the transaction doesn’t *directly* involve any
outputs we control, then it’ll linger around until a restart, when we
try to rebroadcast, and observe that it has bene rejected.
In this commit, we do away with the internal relayFee all together.
Instead, we’ll pass in the fee rate when we’re crafting any
transactions. This allows the caller to manually dictate their desired
fee rate.
During the time of initial block hash catch-up, it is possible to
request an address be generated. This commit updates the active
addresses by calling `w.activeData` after the catch-up is complete.
This changes the database access APIs and each of the "manager"
packages (waddrmgr/wstakemgr) so that transactions are opened (only)
by the wallet package and the namespace buckets that each manager
expects to operate on are passed in as parameters.
This helps improve the atomicity situation as it means that many
calls to these APIs can be grouped together into a single
database transaction.
This change does not attempt to completely fix the "half-processed"
block problem. Mined transactions are still added to the wallet
database under their own database transaction as this is how they are
notified by the consensus JSON-RPC server (as loose transactions,
without the rest of the block that contains them). It will make
updating to a fixed notification model significantly easier, as the
same "manager" APIs can still be used, but grouped into a single
atomic transaction.
