Previously, inserting a transaction as unconfirmed into the store and
later confirming it would leave a lingering unconfirmed input record.
This was discovered as part of
https://github.com/btcsuite/btcwallet/pull/655. This issue would only
affect the wallet if it tracked spent transaction outputs, which it
doesn't. We aim to resolve it in any case for the sake of internal
consistency.
This test ensures that there aren't any lingering unconfirmed records
for a transaction that existed within the store as unconfirmed before
becoming confirmed. At the moment, this is currently failing due to a
gap when moving a transaction from unconfirmed to confirmed within the
store. This will be resolved in a subsequent commit.
This commit ensures the wallet won't enter an inconsitent state
by checking tx confirmation before adding credit.
Without this fix, In the case the existing transaction is already
confirmed on-chain the flow updates the bucketUnminedCredits but
without adding en entry also to the bucketUnmined resulting in
inconsistent state.
In this commit, we move the existing `internal/txsizes` package into its
own package and make it a module along the way. This allows projects
like `neutrino` to depend on a slimmer set of `btcwallet` related
dependencies.
In this commit, we create a new module for `walletdb` in order to allow
external projects to use the project without also having to depend on
the entirety of `btcwallet`. With this commit, projects that depend on
`walletdb` will benefit from a slimmer set of additional dependencies.
A nil txid could've been returned from publishTransaction even if it was
successful. This was due to the underlying SendRawTransaction call
"failing", e.g., when the transaction being broadcast has already
confirmed, but publishTranasction interpreting such failure as a
success.
Since it's now possible for gozmq.Conn to block when calling Receive,
BitcoindConn hangs upon being stopped because its goroutines are waiting
for a message to be delivered. To address this, we modify it to close
its ZMQ connections driving the goroutines once it's been stopped. This
allows the goroutines to unblock by detecting the EOF error and exiting.
We update the dropwtxmgr utility tool to take into account that the
wallet only stores MaxReorgDepth blocks, which introduced an additional
constraint when updating the wallet's synced state. The constraint
ensures that the previous block exists when updating the wallet's synced
state, but this does not hold for the birthday block since it's the
first block we'll store.
In this commit, we speed up creating a fresh wallet when using the btcd
backend. Before this commit, we would need to rescan 10k or so blocks
when creating a new wallet with the btcd backend. btcd will actually
fully scan all the blocks even though we have zero addresses or UTXOs to
look for. As a result, this can take quite some time.
In this commit we modify the starting height of the initial rescan to
start at the birthday height, and only modify it if it's unset, or the
best height of the chain is before this birthday height. As a result, we
won't always have the full 10k block re org safety horizon on disk, but
will tend to this level after we begin to sync forward.
Previously, the wallet would attempt to store the same block it
checkpointed during its initial sync when performing a recovery. This
would cause the previous block existence validation check to be in
place, which would ultimately fail because the previous block was not
stored intentionally.
To address this, we always start/resume our recovery from the wallet's
best height. This also ensures that we do not rescan the same block
again when resuming a recovery after a shutdown.
In this commit we fix a lingering bug in our output sanity checks that
would only show up during time periods of persistently higher fees.
Before this commit we would incorrectly use the fee rate instead of the
min relay fee when checking an output for dust. This would cause us to
mistakenly reject a transaction for having a dust output.
We fix this by falling back to using the current min-relayfee.
