The btclog package has been changed to defining its own logging interface (rather than seelog's) and provides a default implementation for callers to use. There are two primary advantages to the new logger implementation. First, all log messages are created before the call returns. Compared to seelog, this prevents data races when mutable variables are logged. Second, the new logger does not implement any kind of artifical rate limiting (what seelog refers to as "adaptive logging"). Log messages are outputted as soon as possible and the application will appear to perform much better when watching standard output. Because log rotation is not a feature of the btclog logging implementation, it is handled by the main package by importing a file rotation package that provides an io.Reader interface for creating output to a rotating file output. The rotator has been configured with the same defaults that btcd previously used in the seelog config (10MB file limits with maximum of 3 rolls) but now compresses newly created roll files. Due to the high compressibility of log text, the compressed files typically reduce to around 15-30% of the original 10MB file. |

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
