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 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 alter the behavior for handling chain notifications
within the wallet. The previous code would assume that the channel would
close, but due to now using a ConcurrentQueue to handle notifications,
this assumption no longer stands. Now, we'll stop handling notifications
either once the wallet has or stopped or once the notifications channel
has been closed.
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.
This commit makes use of the recently added EstimateVirtualSize
method to estimated the size of a transaction when calculating
fees. This makes fee estimation more accurate when we are spending
segwit outputs, as before we wouldn't account for the witness
descount, resulting in overshooting fee estimates.
This commit adds a new method EstimateVirtualSize that calculates
the worst case estimate vsize for a transaction with a given set
of inputs and outputs. This method is aware of P2PKH, P2WPKH and
P2SH-P2WPKH inputs, and caulculates the transaction vsize with
the witness data included.
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.
This commit makes sure the wallet db is closed if the call to
open the wallet fails, as subsequent calls to OpenExistingWallet
would fail to open the already open database.
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.
