chainntnfs/bitcoindnotify: fix possible panic with lack of txindex
In this commit, we fix a recently introduced bug which can result in a
panic when bitcoind nodes without a txindex active are started. The
issue was that we would still defence the transaction's blockhash, which
would be nil if we detected that the backend didn't have the txindex
active.

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.
