[CompactSealedState] Add import-compact-execution-state-to-storehouse util - #8699
zhangchiqing wants to merge 2 commits into
Conversation
📝 WalkthroughWalkthroughAdds a utility command that imports registers from a validated compacted execution-state checkpoint. It resolves the last finalized and executed block, checks the checkpoint commitment, requires an empty register store, imports registers, and registers the command with the utility CLI.

Merge Risk: 🔵 Low · up to The import utility can report a successful bootstrap even when the register database reports a shutdown error. Propagate that error before merging so operators can detect and recover from a failed command run. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

nit: the EN performs the same import with the configurable --import-checkpoint-worker-count flag (default 10, cmd/execution_config.go:145). Hardcoding 16 diverges without explanation and gives operators no way to tune it.

nit: this re-implements the non-storehouse path of state.GetHighestFinalizedExecuted (engine/execution/state/state.go:549). Consider extracting a shared helper into cmd/util/cmd/common so a future fix to the anchor semantics cannot miss one of the copies.

Return the Pebble close error.
runE logs and discards an error from *pebble/v2.DB.Close, then returns success. The import batches and final height marker already use pebble.Sync, so a close error does not by itself prove that the imported data is incomplete or undurable. It still indicates that Pebble reported a shutdown error, which the command must propagate.
Use a named return value and join the close error with any earlier error. This follows the repository error-handling convention.
Proposed fix
-func runE(*cobra.Command, []string) error {
+func runE(*cobra.Command, []string) (retErr error) {
...
defer func() {
if closeErr := pebbleDB.Close(); closeErr != nil {
- log.Error().Err(closeErr).Msg("cannot close register store db")
+ retErr = errors.Join(retErr, closeErr)
}

Problem
Bootstrapping a storehouse (payloadless) register store requires indexing registers from the root block to the latest height, which takes days on a long-running execution node.
ImportRegistersFromCheckpointcan seed the storehouse from a single-trie checkpoint, andcompact-execution-stateproduces exactly that — a checkpoint at the last sealed and executed block. However, the EN's own startup import is hardwired toroot.checkpointat the sealed root height, so there was no way to seed the register store from the compacted checkpoint.Changes
New util
import-compact-execution-state-to-storehouse(cmd/util/cmd/import-compact-execution-state-to-storehouse), registered incmd/util/cmd/root.go.It requires the EN to be stopped and the execution state to be in the Compacted Sealed State, then:
C, mirroringExecutionState.GetHighestFinalizedExecuted: the executed-block pointer capped by the finalized head, with the commit read from the commits store.--execution-state-diris a compacted single-trie checkpoint whose root hash equalsC(wal.CheckpointHasSingleRootHash).--register-dirdoes not exist or is empty, and that the register store has not been bootstrapped.bootstrap.ImportRegistersFromCheckpoint, which sets the register store's first and latest heights to the resolved height.After that the node starts with storehouse enabled, skips its own root-checkpoint import, and resumes execution at
height + 1, indexing forward only.Verification
