This commit implements so minor changes in formatting: character column
limits, error returning, scoped, errors. The aforementioned changes are
a bit of minor clean up after the merge of the latest PR in order to
ensure the new code in the file conforms to the code style in the rest
of the project.
Moved transaction states from in-memory maps to persistent BoltDB
buckets. This allows channel force closes to operate reliably if the
daemon is shut down and restarted at any point during the forced
channel closure process.
Within the inner loop of the utxoNursery when waiting for a new
sweepable transaction to be confirmed, we now use the new ChainNotifier
API for ConfirmationEvent’s which exposes additional details as to
exactly where in the chain the transaction was ultimately confirmed.
Within the utoxNursery we now use a two value read fro the block epoch
channel in order to exit early if/when the ChainNotifier begins the
shutdown process before the signal reaches the utxoNursery.
This commit removes the previously added contract breach retribution
duties from the utxoNursery. Much of the code removed will instead be
moved to a new sub-system which continuously monitors the state of ALL
active contracts for their entire life time.
This commit expands the duties of the utxoNursery (which should maybe
be renamed), to handle carrying out retribution against a counter-party
who breaches the channel contract by broadcasting a prior revoked state
on-chain.
As part of the retribution, once the breach transaction (the revoked
commitment transaction) has been confirmed within a block, the nursery
then sweep ALL funds pending within the channel to the daemon’s wallet.
This new section of the code has been implemented without full
persistence logic similar to time-locked output sweeping workflow of
the nursery. In a later commit, this section will gain full persistence
logic so the workflows can survive restarts of the daemon.
This commit adds a few workarounds in order to concurrently support the
REST proxy as well as the regular gRPC interface. Additionally,
concrete support for the following RPC calls has been added:
GetTransactions, SubscriptTransactions, SubscribeInvoices, and
NewWitnessAddress.
This commit introduces the utxoNursery. The duty of the utxoNursery is
to watch over CSV-locked immature outputs until they’ve fully matured.
An output is mature once both its sequence lock indicated by the CSV op
code within its output has become active. Once an output is mature the
nursery sweeps the outputs in batches into the source wallet.
The utxoNursery executes its duties once a commitment transaction has
been broadcast on-chain.
