Summary
Adds the
headstatemigration: a resume-safe transform that consolidates the deprecated per-field contract layout (ContractClassHash,ContractNonce,ContractDeploymentHeight) into the singleContractrecord introduced by the new-state work. Gated behind the existing--new-stateflag. First of three new-state migrations.How it works
Iterates the
ContractClassHashbucket to discover every contract address. Four worker goroutines (ingestorCount) read the three deprecated fields per address into shareddb.Batches; one committer drains batches at 96 MB. A semaphore caps in-flight batches atingestorCount + 1. After all records are written, the three deprecated buckets are wiped viaDeleteRange.StorageRootis left zero on each new record — the running node lazily backfills it on the contract's first storage write.What changes
migration/headstate/package (migrator, ingestor, committer, counter, tests).node/migration.goas an optional migration gated bycfg.NewState.state.WriteContractincore/state/accessors.gogains a public overload taking raw fields, used by the migration.Resume safety
state.HasContractskips addresses whose Contract record already exists — no overwrite of newer running-node data.DeleteRangeover any residual ranges; already-empty ranges are no-ops.(shouldRerun, ctx.Err())so the runner re-invokes on next start.
