hypercore-audit

Audit a hypercore's storage

Usage

const core = new Hypercore(dir)

const report = await audit(core.state.storage, { dryRun: true })

console.log(report)

// {
//   treeNodes: 247,
//   blocks: 127,
//   bits: 127,
//   droppedTreeNodes: 0,
//   droppedBlocks: 0,
//   droppedBits: 0,
//   corrupt: false
// }

API

audit(storage, { tree = true, blocks = true, bitfield = true, dryRun = false }

Perform an audit on the storage instance. tree, bitfield and blocks are booleans to specify which components should be checked.

If dryRun is set to false, then any storage discrepancies will be cleaned up and the corrections will be written to the database. NOTE: this is a destructive operation

A report is returned of the form:

{
  treeNodes: 247, // number of valid treeNodes present
  blocks: 127, // number of valid blocks present
  bits: 127, // number of valid blocks present
  droppedTreeNodes: 0, // number of invalid tree nodes
  droppedBlocks: 0, // number of invalid blocks
  droppedBits: 0, // number of invalid bits
  corrupt: false // a core is corrupt if any root nodes are missing
}
