In this commit, we introduce the concept of scopes for individual key
managers. Each scope will lock down a key manager to a particular
purpose and coin type within the BIP0043 hierarchy. Each scope will
also have a set address type schema. This schema will be consulted when
creating addresses for a particular scoped key manager.
Finally, we introduce 3 new default scopes:
* BIP 44
* BIP 84
* BIP 49++ (BIP49 but uses p2wkh for change addresses)
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 add a new method to the Store object that allows
callers to *manually* remove any conflicting transactions. At times,
it’s the case that while we were offline another transaction was
broadcast that double spends our own, or with the existence of RBF,
another replacement transaction was generated. In this case, when we
come back online, the tx will be rejected. Currently, we have no way of
removing such transaction sot avoid the retransmit-then-reject-dance.
This commit fixes that by adding RemoveUnminedTx.
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.
This commit allows neutrino to simulate the GetBlockHeader RPC, and
allows chain client code to use the call with both btcd/RPC back end
and the neutrino back end.
This commit adds support for using StartTime in a rescan in
neutrino. The NeutrinoClient instance can have a birthday set
such that all underlying neutrino rescans are called with that
start time.
