In this commit, we introduce a migration to fix some of the recent issues found w.r.t. the edge update index. The migration attempts to fix two things: 1) Edge policies include an extra byte at the end due to reading an extra byte for the node's public key from the serialized node info. 2) Properly prune all stale entries within the edge update index. As a result of this migration, nodes will have a slightly smaller in size channeldb. We will also no longer send stale edges to our peers in response to their gossip queries, which should also fix the fetching channel announcement for closed channels issue.
channeldb
The channeldb implements the persistent storage engine for lnd and
generically a data storage layer for the required state within the Lightning
Network. The backing storage engine is
boltdb, an embedded pure-go key-value store
based off of LMDB.
The package implements an object-oriented storage model with queries and mutations flowing through a particular object instance rather than the database itself. The storage implemented by the objects includes: open channels, past commitment revocation states, the channel graph which includes authenticated node and channel announcements, outgoing payments, and invoices
