In this commit, we update the Rescan call in the interface to map the
outpoint to the address that the outpoint holds. We do this as BIP 158
has recently been updated to match on the prev output script rather than
the outpoint itself. Additionally, in the near future, btcd (then
bitcoind), will switch over to using the BIP 158 filters internally,
which will also match on the output scripts.
In this commit, we modify the way we store spending transaction hashes
for unconfirmed spends. Now, rather than only keeping track of one
possible unconfirmed spend, we track multiple in order to ensure we
properly handle transaction replacements, like in the case of RBF,
double spends, etc. With this in, the double spent tests recently added
should now pass.
In this commit, we slightly refactor the existing moveMinedTx method
and split it into two: deleteUnminedTx and updateMinedBalance. We do
this as moveMinedTx is no longer moving the transaction from the unmined
bucket to the mined, instead it just removes it from the unmined bucket.
In this commit, we remove most of the common code between insertMinedTx
and moveMinedTx. Now, all the common logic is handled within
insertMinedTx, and moveMinedTx only contains its unique logic.
In this commit, we add a set of double spend tests to ensure that we can
properly detect and handle them. At this point, we do not do this, but a
follow up commit will address this.
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.
This commit also allows bitcoind back-end to return block timestamp
in `BlockStamp()` and prevents logging and notification of events
until after the client wallet requests notifications.
