In this commit, we remove the keep-alive logic within the handler of the
RPCClient struct as this logic already exists within the backing
rpclient.Client instance. In this case, we'd completely stop the
connection after the ping timeout (1 min), which would render the
reconnection logic within rpcclient.Client useless.
In this commit, we fix a small issue where it's possible that we read a
malformed message from the ZMQ connection to bitcoind due to it shutting
down. To fix this, we ensure that the event type is human readable
before attempting to log it.
In this commit, we extend the client's filtering process to also look at
the set of currently watched transactions. The logic to watch for
transaction hashes was previously there, but it was not used to filter
against incoming transactions.
In the previous commit, we modified our BitcoindClient struct to use a
ConcurrentQueue struct to handle its notifications to the caller. Before
this, the BitcoindClient had a goroutine that would handle these
notifications in the background and detect when a OnBlockConnected
notification was received in order to update the best block. Due to this
logic being removed, we now keep track of the best block througout the
struct as a whole.
In this commit, we update bitcoind to also accept a mapping from
outpoint to address for its implementation of the recan RPC. We do this
as in the near future, when bitcoind implements BIP 158 indexing, then
we'll be able to utilize that to do rescans.
In this commit, we fix a recently introduced bug that would cause
callers that attempted to get a spend notifications for a particular
outpoint to no longer get that precise notification. In a prior commit,
in preparation for the new neutrino gcs filter format, we added a
mapping from script to outpoint that will be used by neutrino, and later
other backends as well. However, we still need to match on outpoint
slices for bitcoind today.
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.
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.
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.
