The interface contract on `DBWriter` explicitly states *"May not be atomic. If not atomic, then the caller must provide crash safe atomicity."* ([migration_types.go:39-40](migration_types.go)). + +Per-block guarantees: +- **memiavl writer** applies `oldDBChangeSet`: deletions of the migrated batch + any incoming user writes routed to memiavl. +- **flatkv writer** applies `newDBChangeSets`: inserts for the migrated batch + any incoming user writes routed to flatkv + the new `MigrationBoundaryKey` (or, on the final block, `MigrationVersionKey=1` and a delete of the boundary). +- The two writers can finish in either order. If the process dies between them, on-disk state is split. + +The `MigrationManager` does not implement a write-ahead log of its own; it relies on memiavl's existing changelog WAL for one side and flatkv's commit-snapshot mechanism for the other. There is no two-phase commit across them. + +This is the physical root cause of `A1`, `A2`, and `A3` below. + +--- + +## 4. Failure Mode Catalog + +Each entry uses this format: + +- **Trigger** -- what physical event causes the failure +- **Disk symptom** -- what an operator would observe on disk +- **User symptom** -- what an end-user (RPC caller) would observe +- **Self-recoverable?** -- whether normal restart + continued block production fixes it +- **Detection signal** -- how to tell from outside that this happened +- **Recovery path** -- the sequence of operator/tool steps to fix + +### A1 -- Lost-batch crash (memiavl wrote, flatkv didn't) + +- **Trigger**: process killed after memiavl writer commits the batch deletion but before flatkv writer commits the corresponding insert + boundary advance. +- **Disk symptom**: the migrated batch's evm keys are absent from memiavl (deleted) and absent from flatkv (never inserted). `MigrationBoundaryKey` is at the *previous* batch. +- **User symptom**: those evm keys read as missing. Smart-contract calls touching them revert or read zero. +- **Self-recoverable?** **No** by `MigrationManager` itself. memiavl's WAL replay restores the *committed* state (post-deletion); it does not put the keys back. +- **Detection signal**: post-restart, walk memiavl evm and flatkv evm; the *union* is missing keys that exist in any pre-migration backup or peer node at the same height. +- **Recovery path**: state-sync from a peer at a >= V1 height; or, if a pre-migration memiavl backup exists, restore it and replay changesets via `replay-changelog`. + +### A2 -- Stale-residue crash (flatkv wrote, memiavl didn't) + +- **Trigger**: process killed after flatkv writer commits the batch insert + new `MigrationBoundaryKey` but before memiavl writer commits the corresponding deletions. +- **Disk symptom**: migrated batch keys exist in *both* memiavl and flatkv. `MigrationBoundaryKey` claims the batch is migrated. +- **User symptom**: none -- `MigrationManager.Read` consults the boundary first, routes the read to flatkv (newDB), and returns the correct value. Memiavl residue is invisible to consumers. +- **Self-recoverable?** **Yes for correctness, no for disk usage.** Block production continues correctly; memiavl just keeps stale rows around forever. +- **Detection signal**: walk memiavl evm at any later block; any key whose logical_k <= boundary cursor is residue. After V1 reaches steady state (boundary deleted, `MigrationVersionKey=1`), *every* memiavl evm key is residue. +- **Recovery path**: tool to walk memiavl evm and delete keys covered by the boundary (or all keys, in V1). Disk-only repair; no consensus-visible state changes. + +### A3 -- Boundary key corruption + +- **Trigger**: media corruption / partial-write / human error truncating or mutating `MigrationBoundaryKey` in the flatkv `MigrationStore`. +- **Disk symptom**: `MigrationBoundaryKey` either deserializes to an out-of-range cursor, fails to deserialize at all, or claims a position inconsistent with what memiavl/flatkv physically contain. +- **User symptom**: depending on the corruption: reads route to wrong DB; node refuses to start when `readMigrationBoundary` returns an error in [migration_manager.go:212-225](migration_manager.go). +- **Self-recoverable?** **No**. +- **Detection signal**: deserialize fails on startup; or boundary deserializes but invariant `for every evm key K, K is in exactly one of {memiavl, flatkv}` is violated. +- **Recovery path**: stop the node; reconstruct the cursor by walking both DBs and choosing the cursor consistent with the actual key partition; re-write `MigrationBoundaryKey`. Requires a tool (no current way to do this safely). + +### B1 -- Mid-migration snapshot creation + +- **Trigger**: operator runs cosmos-sdk snapshot at a height when MigrateEVM is in progress. +- **Disk symptom** (intended): a snapshot blob containing both memiavl evm > boundary and flatkv evm <= boundary, plus the boundary itself, plus all other modules from memiavl. +- **Risk**: [composite/store.go:358-378](../composite/store.go) only attaches `flatkvExporter` when `cs.config.WriteMode == config.SplitWrite || cs.config.WriteMode == config.DualWrite`. During MigrateEVM the live `WriteMode` is `MigrateEVM`, which is *not* in that list. **It is unverified that the composite exporter currently produces a coherent mid-migration snapshot.** This is an open question (sec 8). +- **User symptom**: a peer that restores from this snapshot may not converge to a state matching the source. +- **Self-recoverable?** Not applicable. +- **Detection signal**: on the receiving side, `composite.Importer` finishes but post-restore consistency checks (sec 6 / T2) report disagreement. +- **Recovery path**: do not snapshot mid-migration until exporter coverage is confirmed; or fix exporter; or document an operational rule. + +### B2 -- Mid-migration state-sync receive + +- **Trigger**: a node at V0 or in transition receives state-sync from a peer at V1. +- **Disk symptom** (intended): receiver's `composite.Importer` ([composite/store.go:381-396](../composite/store.go)) opens both cosmos and flatkv importers; cosmos receives the non-evm portion, flatkv receives the evm portion. flatkv's `resetForImport` wipes the receiver's flatkv first; cosmos applies the snapshot to memiavl (which presumably also resets evm). On finalize, `MigrationVersionKey=1` is written to flatkv `MigrationStore`. +- **Risk**: the cosmos side of the importer needs to *not* leave residual evm keys in memiavl. If memiavl is not reset for the evm module specifically, the receiver lands in `A2`-equivalent state immediately on restore. +- **User symptom**: post-restore, evm queries return correct values (routed to flatkv via V1's `buildEVMMigratedRouter`) but memiavl carries garbage. +- **Self-recoverable?** Yes, but disk-wasteful, same as `A2`. +- **Detection signal**: post-state-sync, walk memiavl evm; in V1 it should be empty. +- **Recovery path**: reuse the `A2` cleanup tool. + +### C1 -- flatkv corruption after V1 + +- **Trigger**: post-V1, the flatkv directory is partially or fully lost (disk failure, accidental `rm -rf`). +- **Disk symptom**: missing or broken flatkv data DBs; memiavl unchanged but already empty for `evm/`. +- **User symptom**: evm reads fail or return missing data. +- **Self-recoverable?** **No**, and *not locally recoverable*: memiavl no longer has the source data after V1. +- **Detection signal**: flatkv fails to open / startup panic. +- **Recovery path**: state-sync from a peer at >= V1. The local-import tool from this branch (`import-flatkv-from-memiavl`) **cannot help** post-V1 because memiavl is empty. The only local fallback is restoring from a pre-V1 memiavl snapshot plus changeset replay, which is rarely available in production. + +### C2 -- memiavl evm residue after V1 (lingering A2) + +- **Trigger**: any uncleaned-up `A2` from the transition phase, or a `B2`-equivalent state-sync that did not wipe memiavl evm. +- **Disk symptom**: memiavl evm contains keys; `MigrationVersionKey=1` so router sends evm reads to flatkv. +- **User symptom**: none. +- **Self-recoverable?** No. +- **Detection signal**: count of evm keys in memiavl > 0 in V1. +- **Recovery path**: same tool as `A2` cleanup. + +### C3 -- V1 completion audit + +- **Trigger**: not a failure per se -- an operator/CI wants to verify "we landed at V1 correctly and did not drop anything during the transition". +- **Invariant**: `set(evm keys in flatkv at V1) == set(evm keys in memiavl at V0_pre_migration) evolved by all changesets between V0 start height and V1 final height`. +- **Detection signal**: a digest computed over flatkv@V1 evm matches an externally-recorded ground-truth digest for that height. +- **Recovery path**: not a recovery; an audit. Failure here implies an unnoticed `A1` or worse. + +--- + +## 5.

Output schema is stable across calls and documented in command help; CI assertions can grep individual lines. +6. Missing flatkv dir is reported as a clear error, not a panic. +7.

The `union-invariant` mode is the largest piece because it must classify each iterator key against a deserialized boundary. + +**Acceptance criteria**: +1. `completion-check` succeeds on a freshly imported, marked-as-V1 state. +2. `completion-check` fails with `keys-in-memiavl: ` when stale evm exists in memiavl post-V1 (synthetic residue). +3. `union-invariant` succeeds on a synthetic mid-migration setup where the boundary is consistent with the partition, and fails when one key is moved from flatkv to memiavl (simulating `A2`). +4. `ground-truth` succeeds when fed the digest produced by the same tool against a reference state, and fails (with sample listing) when a single byte is mutated in any value. +5. Modes are mutually exclusive; help text explicitly lists which failure-mode IDs each mode targets. +6.

The `recompute-boundary` mode is small but has to be cautious about edge cases (empty flatkv, partial overlap). + +**Acceptance criteria**: +1. Without `--apply`, never changes either DB's bytes (acceptance test diffs the data dir before/after). +2. `clean-stale-memiavl --apply` deletes exactly the keys identified in dry-run; idempotent on re-run (second invocation reports no deletions). +3. `recompute-boundary --apply` reproduces the boundary key bytes that would have existed had the original `MigrationManager` advance committed normally (compare against a known-good fixture). +4.

Refuses `recompute-boundary` when `{memiavl evm} cap {flatkv evm} != empty`, emitting a clear "irreconcilable; rerun T2 union-invariant" message. +6. After `clean-stale-memiavl --apply` followed by `migrate-evm-status`, `consistency-flag-keys-in-both == 0`. +7. Documented in command help that this is destructive; help text lists prerequisites. + +### T4 -- `import-flatkv-from-memiavl` extension flags + +**Purpose**: use the existing import tool as a fixture-builder for V1 and mid-migration test scenarios. + +**New flags on the existing command** ([import_flatkv_from_memiavl.go](../../../tools/cmd/seidb/operations/import_flatkv_from_memiavl.go)): + +- `--mark-as-migrated=evm`: + - after the existing import completes successfully, write `MigrationVersionKey=Version1_MigrateEVM=1` into flatkv `MigrationStore` + - covers test fixture #11 (seed a V1 node directly without running migration) + - **does not** touch memiavl; for a clean V1 fixture the caller must also ensure memiavl has no evm (either fresh memiavl or run T3 clean-stale-memiavl) +- `--up-to-boundary=`: + - filter the memiavl walk to only emit keys with logical_k <= boundary + - after import, write the boundary into flatkv `MigrationStore` with `MigrationVersionKey=0` + - covers test fixture #12 (seed a mid-migration node) + +Both flags are off by default; default behavior of `import-flatkv-from-memiavl` is unchanged. + +**Audience**: primarily CI / dev test fixtures. Operators in DR scenarios should not need either flag. + +**Safety rails**: both flags require `--force` (matching the existing tool's posture about overwriting flatkv); `--mark-as-migrated` requires that the import step succeeded (no marking on partial imports). If `Abort` was triggered, no metadata is written. + +**Coverage**: test-side coverage of #11 (`--mark-as-migrated`) and #12 (`--up-to-boundary`). + +**Library dependencies**: existing import path; flatkv `Set`/`Commit` for the metadata write. + +**Complexity**: ~80 LOC + ~120 LOC tests. + +**Acceptance criteria**: +1. Default invocation (no new flags) is byte-identical to the previous behavior; existing tests still pass without modification. +2. `--mark-as-migrated=evm` post-import: `MigrationVersionKey=1` is present in flatkv `MigrationStore`; `migrate-evm-status` reports `stage: v1`. +3. `--mark-as-migrated=evm` after a failing import (Abort path) does not write `MigrationVersionKey`. +4. `--up-to-boundary=`: after import, flatkv contains exactly the keys with logical_k <= boundary, no more, no fewer; boundary in `MigrationStore` matches the flag. +5. `--up-to-boundary` plus `migrate-evm-status` reports `stage: transition` with the same boundary. +6. Both flags can be combined sensibly only if the user understands the result; if combined, the tool emits a warning explaining the resulting state is not reachable through normal MigrateEVM execution. + +--- + +## 7. Suggested Sequencing + +Order matters because each step's verification leans on the previous step's tools. + +1. **T1 (status)** -- foundational. Tiny, read-only, immediately useful to attach to any incident response. Also unblocks T2 and T3 by providing the boundary-read helper. +2. **T2 completion-check sub-mode** -- smallest verify mode, depends only on T1 helpers. Once landed, attach to the existing docker integration test so the post-import smoke check upgrades from "6 RPC samples" to "memiavl evm count is zero + flatkv evm count is non-zero + V1 metadata present". +3. **T2 union-invariant sub-mode** -- needs careful boundary partition logic; valuable for catching `A1`/`A2`/`A3` in development of MigrationManager itself. +4. **T4 `--mark-as-migrated`** -- small. Once it lands, downstream test fixtures can build V1 nodes in seconds, accelerating T2 and T3 tests. +5. **T3 clean-stale-memiavl** -- first writable tool. Land only after T2 union-invariant is stable, so we have an external invariant check to validate T3's effects. +6. **T3 recompute-boundary** -- second writable tool. Requires T1 + T2 union-invariant. +7. **T2 ground-truth sub-mode** + **T4 `--up-to-boundary`** -- nice-to-have polish; ground-truth needs a digest-management policy (sec 8) before it pays off. + +The sequence is designed to land all read-only verification before any writable repair tool, so no `--apply` ever runs without an external invariant check available to validate it. + +--- + +## 8. Open Design Questions (deferred to PR-time) + +Listed here so they aren't silently decided wrong: + +- **B1 mid-migration snapshot validity**: [composite/store.go:369](../composite/store.go) gates `flatkvExporter` on `WriteMode in {SplitWrite, DualWrite}`. During `MigrateEVM` the live `WriteMode` is `MigrateEVM`. Does `composite.Exporter` produce a coherent snapshot in that mode, or does it silently exclude flatkv? This needs a focused test before any operator workflow assumes mid-migration snapshots are safe. Likely outcome: a separate design doc, plus a fix in composite/store.go. +- **Ground-truth digest provenance**: T2 `--mode=ground-truth` requires a trusted digest. Who computes it, how is it published, and at what cadence? Options: per-release published digest; per-validator self-signed digest; epoch-based on-chain attestation. Choose at PR time. +- **T3 irreconcilable-state policy**: when `recompute-boundary` finds keys in both DBs that cannot be partitioned into "above/below boundary", default behavior options are (a) refuse, (b) quarantine the duplicates, (c) trust flatkv and delete from memiavl, (d) trust memiavl and delete from flatkv. Refuse is safest; choose at PR time with input from the migration owners. +- **In-process tooling vs out-of-process**: all tools in this roadmap assume `seid` is stopped. If on-line equivalents are desired (e.g., `seid migrate-evm doctor`), how do they coexist with `MigrationManager`'s mutex guarantees? Default: do not build on-line tools; require operator to stop the node. +- **Module-level prune**: the existing `prune` is version-level. If `T3 clean-stale-memiavl` ends up being implemented essentially as "delete every key under module `evm/` from memiavl", consider exposing it as a more general `prune-module` command rather than a migration-specific subcommand. Decide at PR time based on whether the V1->V2 migration will need the same primitive. + +--- + +This roadmap intentionally produces **no Go code**. The next step is to socialize this document, agree on the sequencing in sec 7, and then split each tool into its own PR with its own design discussion. diff --git a/sei-db/tools/cmd/seidb/main.go b/sei-db/tools/cmd/seidb/main.go index 8a026d59f9..ffb46fc93e 100644 --- a/sei-db/tools/cmd/seidb/main.go +++ b/sei-db/tools/cmd/seidb/main.go @@ -26,6 +26,8 @@ func main() { operations.DumpIAVLCmd(), operations.DumpFlatKVCmd(), operations.StateSizeCmd(), + operations.MemiavlLatestVersionCmd(), + operations.ImportFlatKVFromMemiavlCmd(), operations.ReplayChangelogCmd(), operations.TraceProfileReportCmd()) if err := rootCmd.Execute(); err != nil { diff --git a/sei-db/tools/cmd/seidb/operations/import_flatkv_from_memiavl.go b/sei-db/tools/cmd/seidb/operations/import_flatkv_from_memiavl.go new file mode 100644 index 0000000000..a84f0f4a42 --- /dev/null +++ b/sei-db/tools/cmd/seidb/operations/import_flatkv_from_memiavl.go @@ -0,0 +1,384 @@ +package operations + +import ( + "context" + "errors" + "fmt" + "math" + "os" + "path/filepath" + "strings" + + errorutils "github.com/sei-protocol/sei-chain/sei-db/common/errors" + "github.com/sei-protocol/sei-chain/sei-db/common/keys" + "github.com/sei-protocol/sei-chain/sei-db/common/utils" + "github.com/sei-protocol/sei-chain/sei-db/proto" + "github.com/sei-protocol/sei-chain/sei-db/state_db/sc/flatkv" + flatkvconfig "github.com/sei-protocol/sei-chain/sei-db/state_db/sc/flatkv/config" + "github.com/sei-protocol/sei-chain/sei-db/state_db/sc/memiavl" + sctypes "github.com/sei-protocol/sei-chain/sei-db/state_db/sc/types" + "github.com/spf13/cobra" +) + +// importBatchSize bounds how many memiavl key/value pairs we hand to a single +// flatkv.ImportTranslator.Translate call.
