In this commit, we add the current chain parameters to the
BitcoindNotifier. This will be used in a future commit in order to
convert outputs scripts into addresses. This is needed since the
bitcoind backend uses these addresses to detect whether the script
encoded within it was spent by a transaction in the chain.
In this commit, we add the current chain parameters to the BtcdNotifier.
This will be used in a future commit in order to convert outputs scripts
into addresses. This is needed since the btcd backend uses these
addresses to detect whether the script encoded within it was spent by a
transaction in the chain.
In this commit, we refactor the TxNotifier's ProcessRelevantSpendTx to
also detect script spends. This can easily be done as the transaction
filtering logic was refactored into its own method in a previous commit.
In this commit, we modify the TxNotifier's ConnectTip method to also
detect whether a registered script has been confirmed or spent on-chain
by a transaction in the connected block. Once detected, notifications
for them will be queued up for dispatch as with txids/outpoints.
We've also refactored the ConnectTip method into smaller and reusable
methods, which will serve useful later.
In this commit, we refactor the HeightHintCache and its underlying
interfaces to be able to manipulate hints for ConfRequests and
SpendRequests. By doing so, we'll be able to manipulate hints for
scripts if the request includes either a zero hash or a zero outpoint.
These structs allow us to request notifications for either
txids/outpoints or output scripts. We'll be using these in later commits
to index confirmation and spend requests within the TxNotifier.
This commit defines a new heuristic WeightedCombAttachment that takes a
set of sub-heuristics, and produces a final node score by querying the
sub-heuristics and combining the scores from them according to their
weights.
This way it will look like a regular, single heuristic to the autopilot
agemnt, but can be a more complex combination of several.
To prepare for combinning scores from multiple heuristics, we require the
scores returned from the NodeSores API to be in the range [0.0, 1.0].
The prefAttach heuristic is altered to scale the returned scores such
that the most connected node in the grpah is given a score of 1.0.
In this commit, we update the release script to include a directory
containing all of our vendored dependencies. This makes out releases
more self contained as they can be built using `go build -mod=vendor`
without requiring any package fetching.
Additionally, we pacakge the entire source as well.
Fixes#1550.
In this commit, we add a new section to the code contribution guidelines
explaining how to use `go mod replace`. This will be a common procedure
for any developer that needs to make a change in any of our sister
projects, so it's nice to have this outlined in a single place.
Since the chain backend and miner is now seperate nodes, the reorg test
must be slightly rewritten. We use the Btcd Node RPC to connect and
disconnect the three bitcoin nodes in question (chain backend, miner,
temp miner) to control the reorg scenario.
