channeldb: create new channeldb package, update lnwallet to use new API * Initial draft of brain dump of chandler. Nothing yet set in stone. * Will most likely move the storage of all structs to a more “column” oriented approach. Such that, small updates like incrementing the total satoshi sent don’t result in the entire struct being serialized and written. * Some skeleton structs for other possible data we might want to store are also included. * Seem valuable to record as much data as possible for record keeping, visualization, debugging, etc. Will need to set up a time+space+dirty cache to ensure performance isn’t impacted too much. 2015-12-26 21:35:15 +03:00			`package channeldb`
channeldb: switch to Open/Create methods rather than New Commit includes basic tests for Open/Create. Additionally, rather than relying on btcwallet’s addmgr for encryption/decryption, this package now exposes a simple crypto system interface. 2016-03-24 08:11:57 +03:00

channeldb: modify schema to multiple-channels-per-peer This commit overhauls the current schema for storing active channels in order to support tracking+updating multiple open channels for a particular peer. Channels are now uniquely identified by an output (txid:index) rather than an arbitrary hash value. As a result, the funding transaction is no longer stored, as only the txin is required to lookup the original transaction, and to sign for new commitment states. A new bucket, nested within the bucket for a node’s Lightning ID has been created. This new bucket acts as an index to the active channels for a particular peer by storing all the active channel points as keys within the bucket. This bucket can then be scanned in a linear fashion, or queried randomly in order to retrieve channel information. The split between top-level, and channel-level keys remains the same. The primary modification comes in using the channel ID (the funding outpoint) as the key suffix for all top-level and channel-level keys. 2016-06-21 07:39:50 +03:00			`ErrNoExists = fmt.Errorf("channel db has not yet been created")`
