This is a temporary utility command that performs a force compaction on the state

once the node has stopped. This command will likely be omitted in the future after
the planned refactor to the storage engine.

All calls that can be tracked back to a block header by a proof
will be verified before passing them back to the caller. Other than
that, it will present the same interface as a full CometBFT node.

Furthermore to the chainID, a fresh instance of a light client will
need a primary RPC address, a trusted hash and height and witness RPC addresses
(if not using sequential verification). To restart the node, thereafter
only the chainID is required.

When /abci_query is called, the Merkle key path format is:

	/{store name}/{key}

Please verify with your application that this Merkle key format is used (true
for applications built w/ Cosmos SDK).

reindex-event is an offline tooling to re-index block and tx events to the eventsinks,

reindex from the base block height(inclusive); and the default end-height is 0, meaning 
the tooling will reindex until the latest block height(inclusive). User can omit
either or both arguments.

want to use this command.

Functions

func AddNodeFlags

func AddNodeFlags(cmd *cobra.Command)

AddNodeFlags exposes some common configuration options on the command-line These are exposed for convenience of commands embedding a CometBFT node

func NewRunNodeCmd

func NewRunNodeCmd(nodeProvider nm.Provider) *cobra.Command

NewRunNodeCmd returns the command that allows the CLI to start a node. It can be used with a custom PrivValidator and in-process ABCI application.

func ParseConfig

func ParseConfig(cmd *cobra.Command) (*cfg.Config, error)

ParseConfig retrieves the default environment configuration, sets up the CometBFT root and ensures that the root exists

func RollbackState

func RollbackState(config *cfg.Config, removeBlock bool) (int64, []byte, error)

RollbackState takes the state at the current height n and overwrites it with the state at height n - 1. Note state here refers to CometBFT state not application state. Returns the latest state height and app hash alongside an error if there was one.
