Olaoluwa Osuntokun c575107607 chaintnfs/btcdnotify: make cancellation of block epoch synchronous This commit is meant to fix an occasional flake in the interrogation tests cause by the async nature of the cancellation of block epoch notifications. This commit modifies the cancellation to now be fully synchronous which should eliminate this flake.		2017-04-26 21:17:35 -07:00

chainntnfs

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.
