chainntnfs/txconfnotifier: set confset details at tip
This commit ensures that a confSet's details
are assigned in the confNotifications index
after discovering the transaction at tip. The
recent changes allow a later notification to
be dispatched on registration if an earlier one
has already discovered the confirmation details.

Before this change, it was observed that a later
registration would attempt an immediate delivery,
but fail to do so because the confset's details
were nil. This commit remedies that dispatch path,
allowing the integration tests to pass again.

Build Status MIT licensed GoDoc

The chainntnfs package implements a set of interfaces which allow callers to receive notifications in response to specific on-chain events. The set of notifications available include:

  • Notifications for each new block connected to the current best chain.
  • Notifications once a txid has reached a specified number of confirmations.
  • Notifications once a target outpoint (txid:index) has been spent.

These notifications are used within lnd in order to properly handle the workflows for: channel funding, cooperative channel closures, forced channel closures, channel contract breaches, sweeping time-locked outputs, and finally pruning the channel graph.

This package is intentionally general enough to be applicable outside the specific use cases within lnd outlined above. The current sole concrete implementation of the ChainNotifier interface depends on btcd.
