This commit removes the MarkEdgeZombie method from channeldb. This method is currently not used in any live code paths in production, and is only used in unit tests. However, incorrect usage of this method could result in an edge being present in both the zombie and channel indexes, which deviates from any state we would expect to see in production. Removing the method will help mitigate the potential for writing incorrect unit tests in the future, by forcing zombie edges to be created via the relevant, production APIs, e.g. DeleteChannelEdge. The existing unit tests that use this method have been modified to use the DeleteChannelEdge instead. No regressions were discovered in the process.
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
