From fffc513f38f16de9bb38b0f7addb741bd1ae3e7b Mon Sep 17 00:00:00 2001 From: Lukasz Klimek <842586+lklimek@users.noreply.github.com> Date: Mon, 25 May 2026 17:38:03 +0200 Subject: [PATCH 01/38] refactor(platform-wallet)!: typed PersistenceError with kind + source (CODE-004) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace `PersistenceError::Backend(String)` with `Backend { kind: PersistenceErrorKind, source: Box }` so the persistor's `is_transient()` contract reaches consumers without round-tripping through a stringified message. `PersistenceErrorKind` carries the retry policy explicitly — `Transient` (caller MAY retry), `Constraint` (SQL constraint / FK / integrity, caller bug), `Fatal` (everything else). The kind enum is wildcard-free at every consumer match site so a future addition forces an explicit classification update. Persistor side: `From for PersistenceError` delegates to a new `WalletStorageError::persistence_kind` that folds in `is_transient()` plus SQLite `ConstraintViolation` detection. The boxed source preserves the typed `WalletStorageError` chain so consumers can `Error::source()`-walk to the inner rusqlite payload — the previous `DisplayChain` flattening goes away. Backward compat: - `PersistenceError::backend(source)` defaults to `Fatal` kind. - `PersistenceError::backend_with_kind(kind, source)` for callers that classify (the storage `From` impl). - `From` / `From<&str>` still work and default to `Fatal` — keeps FFI's `format!(...).into()` sites compiling. This is a breaking change for any out-of-tree impl that pattern-matched `PersistenceError::Backend(String)`. In-tree consumer call sites still only log + proceed; the semantic upgrade to inspect `is_transient()` + retry is T-003 (Wave 2). Tests: - `platform-wallet/tests/persistence_error_taxonomy.rs` — 5 tests covering TC-CODE-004-a (kind shape + exhaustiveness), -c (source is `Send + Sync` + Display), -e (`From` defaults to Fatal). - `platform-wallet-storage/tests/persistence_error_kind_mapping.rs` — 7 tests covering TC-CODE-004-b (transient / constraint / fatal mapping table + chain preservation) and TC-CODE-004-e (wildcard-free invariant guard on `is_transient` / `error_kind_str` outer-Self match via source-text parse). - TC-CODE-004-d (consumer-side retry on Transient) is T-003 per Nagatha's plan, not T-001.

The cascade chain becomes wallet_metadata → identities → identity-owned objects so the consumer can pass the real owning `wallet_id` (or NULL for orphan identities) without inventing the `WalletId::default()` sentinel that V001's FK silently rejected. Schema changes (V001 → V002): - identities: PK (identity_id); wallet_id BLOB nullable, FK cascade - identity_keys: drop wallet_id; PK (identity_id, key_id); FK identity_id - dashpay_profiles: drop wallet_id; PK identity_id; FK identity_id - dashpay_payments_overlay: drop wallet_id; PK (identity_id, payment_id); FK identity_id - token_balances: drop wallet_id; PK (identity_id, token_id); FK identity_id - wallet-scoped tables (accounts, core_*, platform_*, asset_locks, contacts_*, wallet_metadata) unchanged Sentinel-row guard: V002 refuses to run if `token_balances` carries legacy rows with `wallet_id = X'00…00'`. Implemented via a CHECK on a temp table; the persister open path re-classifies the failure as `WalletStorageError::MigrationRequiresManualCleanup { table, count }` so operators see what to drop instead of a cryptic rusqlite error. Migration discipline: `run_for_open` disables `PRAGMA foreign_keys` before BEGIN (and re-enables with assertion on exit). SQLite fires `ON DELETE CASCADE` on children when their parent is dropped during the 12-step ALTER, even under `defer_foreign_keys` — wiping the rows we're migrating. FKs cannot be toggled inside a tx, hence the wrapper. Consumer side (`identity_sync.rs`): removed the `WalletId::default()` sentinel. `IdentitySyncManager` now carries an identity → `Option` map populated via the new `register_identity_with_wallet` method; `apply_fresh_balances` looks the wallet id up and passes it to `persister.store(...)`. The legacy `register_identity` shim defaults to `None` (orphan) so FFI callers continue to compile unchanged — V002's nullable `identities.wallet_id` accepts the orphan case. PER_WALLET_TABLES gains a `WalletScope { DirectColumn, ViaIdentity }` discriminant; counting/inspect queries now route through `count_rows_for_wallet_sql` so identity-scoped tables JOIN through `identities` to find rows belonging to a wallet. `delete_wallet` is unaffected — cascade still flows from `wallet_metadata`. Tests: - NEW `sqlite_v002_migration.rs` (6 TCs covering rows-preserved, cascade-chain, orphan identity, real wallet_id token write, sentinel-row refusal end-to-end, post-migration foreign_key_check) - Existing migration / round-trip / delete-wallet / hardening tests updated to the V002 schema (column lists, identity row seeding via the new `ensure_identity` helper) - Error-classification table extended with the new variant; gate remains wildcard-free Closes CODE-002.

When the persister reports `LOAD_UNIMPLEMENTED = &["ClientStartState::wallets"]` (today's `SqlitePersister` contract, pending PR #3692), the loop body never executes — and every persisted platform-address slice silently drops at function scope. The host's per-wallet `register_wallet` re-fetch path does in fact deliver the addresses correctly, so there is no actual data loss on PR #3625 today. But the silent-drop is a code smell that will absolutely bite the next caller who reaches for `load_from_persistor` expecting the documented contract. Gate the consumer: when `wallets.is_empty() && !platform_addresses.is_empty()`, return a new typed `PlatformWalletError::PersistorMissingWalletRehydration` carrying the unimplemented-area list and the orphan slice count. The host then either waits for #3692 to land or falls back to per-wallet `register_wallet`. Tests: - TC-CODE-001-a: persister returning two orphan platform_addresses slices → `PersistorMissingWalletRehydration { orphan_addresses_count: 2 }` - Negative control: empty persister payload (the `NoPlatformPersistence` shape) still succeeds — gate only trips for the orphan case.

Every subsequent per-wallet write then FK-violates against the missing parent (CODE-002 territory). Drive the typed `PersistenceError` kind off the wire (introduced by CODE-004 / T-001): - `Transient` (e.g. `SQLITE_BUSY`): one 50ms backoff retry; if the retry succeeds the wallet registers normally. - `Fatal` / `Constraint` / `LockPoisoned`: undo the in-memory `wallet_manager` insert and surface the new `PlatformWalletError::WalletRegistrationFailed { wallet_id, reason }` variant. The retry path uses `tokio::time::sleep` (already in tree) and clones the registration changeset once — `PlatformWalletChangeSet` already derives `Clone`. Tests: - TC-CODE-018-a: scripted `Fatal` store → returns `WalletRegistrationFailed`, single store attempt (no retry), `wallet_ids()` is empty. - TC-CODE-018-b: scripted `Transient → Ok` → succeeds, wallet appears in `wallet_ids()`, store called at least twice (original + retry).

charset=UTF-8 Content-Transfer-Encoding: 8bit Surface SQLite's cascade-delete through the trait so consumers don't need a concrete backend. `DeleteWalletReport` moves from `platform-wallet-storage` into `platform-wallet::changeset::traits` (the trait owns its return types) — SqlitePersister keeps its inherent `delete_wallet` (returns `WalletStorageError` for callers that want the typed error) and adds a trait impl that delegates through the existing `delete_wallet_inner` helper, mapping the `WalletStorageError` chain into a classified `PersistenceError`. `PlatformWalletManager::remove_wallet` now calls `persister.delete_wallet` after the in-memory cleanup. Error policy mirrors `register_wallet` (CODE-018): transient → one backoff retry; anything else → log structured context and continue (the user wanted this wallet gone, in-memory state is already cleaned up, orphan rows can be reaped by an admin tool out-of-band). Trait default returns an empty `DeleteWalletReport` keyed by the requested id, so backends with no per-wallet disk state (`NoPlatformPersistence`, `FFIPersister`) inherit cleanly with no explicit impl required. TC-CODE-003-1/2/3 exercise happy path + fatal-error + transient-retry through `PlatformWalletManager::remove_wallet` with a recording persister. `tests/sqlite_trait_dispatch.rs` adds two more cases for the trait default and the SQLite trait impl round-trip.

SqlitePersister splits the inherent `commit_writes` body into a private `commit_writes_inner` helper that both the inherent and trait method delegate to — no behavioral drift, no duplication. Trait default returns an empty `CommitReport`, so backends that flush inline (`FlushMode::Immediate` on SQLite) or have nothing to buffer (`NoPlatformPersistence`, `FFIPersister`) inherit cleanly with no explicit impl required. TC-CODE-026-1/2 cover the default-impl empty-report contract and the SQLite trait round-trip flushing two dirty wallets durably.

From fc921d313ee38ce98f4b72ebb1c986a6f15390e4 Mon Sep 17 00:00:00 2001 From: Lukasz Klimek <842586+lklimek@users.noreply.github.com> Date: Mon, 25 May 2026 19:26:23 +0200 Subject: [PATCH 07/38] refactor(platform-wallet-storage)!: SQLite-native EXCLUSIVE replaces flock; drop fs2 dep (CODE-005/007/010/015) Cross-process exclusion for `restore_from` and `delete_wallet` now uses SQLite-native `BEGIN EXCLUSIVE` against the destination DB instead of the prior `fs2::FileExt::try_lock_exclusive` advisory lock. Advisory `flock(2)` doesn't interlock with SQLite's own page locking, so a peer rusqlite Connection could race the restore swap (CODE-005) or commit rows between the pre-delete backup snapshot and the cascade delete (CODE-007). With the SQLite-native primitive peers conflict for real: they wait on `busy_timeout`, then surface BUSY / RestoreDestinationLocked. `restore_from` opens a short-lived RW connection on the destination, issues `BEGIN EXCLUSIVE` (mapped to RestoreDestinationLocked on BUSY/LOCKED), and DROPS that connection BEFORE `tmp.persist` so SQLite releases its file handle on the old inode before the atomic rename. `delete_wallet` runs the pre-delete backup BEFORE acquiring EXCLUSIVE (rusqlite's online backup can't establish itself when the source conn is in an active write tx), then takes EXCLUSIVE for the cascade. A structured `info!` fires when the wallet's row footprint differs across the EXCLUSIVE acquisition so operators can correlate peer-committed-between-snapshot-and-lock scenarios. A `TODO(T-007/CODE-006)` marks the pre-backup flush slot that T-007 will fill inside the same EXCLUSIVE window. `fs2` is removed from `Cargo.toml`, the dep feature gate, and `Cargo.lock` (zero remaining transitive uses). The stale README "advisory-lock warning" and `backup.rs` rustdoc are rewritten to describe the real (SQLite-native) primitive. The Err arm that emitted `"advisory lock unsupported on this filesystem"` (CODE-010 false-positive downgrade) is gone with the flock block.

Without this fix, rollback-from-backup could not recover a wallet whose only state lived in the merge buffer (`FlushMode::Manual` + un-flushed). Implementation: after draining the wallet's buffered changeset, the delete path opens its own EXCLUSIVE tx and applies the changeset via the newly extracted `apply_changeset_to_tx` helper (factored out of `write_changeset_in_one_tx` so both call sites share schema-write logic). The pre-flush commits BEFORE `run_auto_backup` runs, so the snapshot captures the previously-buffered rows. On flush failure the buffer is restored via the existing CMT-002 restore path and the delete is aborted with no backup left behind. The cascade-side backup still runs before the cascade's own `BEGIN EXCLUSIVE` (rusqlite's `Backup::new` can't establish a backup whose source connection holds an active write tx — `sqlite3_backup_step` deadlocks against the in-flight EXCLUSIVE). A cross-process peer that mutates the wallet between snapshot and lock is handled by the existing post-EXCLUSIVE re-check, which logs the footprint change and proceeds — the cascade reports zero per-table counts when the peer beat it to every row. Tests (TC-CODE-006-{1,2,3}): - `pre_delete_backup_includes_buffered_writes`: renamed from `pre_delete_backup_excludes_buffered_writes`; assertion flipped to require the buffered rows to appear in the backup. - `pre_flush_failure_preserves_buffer_and_skips_backup`: primes the pre-flush injector to fail; asserts buffer survives, backup dir is empty, wallet still in live DB, original error propagated. - `peer_delete_between_backup_and_exclusive_returns_ok_with_zero_counts`: arms a post-backup hook that opens a sibling raw connection and deletes the wallet's metadata row in the gap between snapshot and EXCLUSIVE; asserts the cascade returns Ok with zero counts and the backup carries the pre-peer-deletion state. Test-only helpers added (gated by `cfg(test)` / `__test-helpers`): - `arm_post_backup_hook` — fires once between backup and EXCLUSIVE. - `force_next_pre_flush_to_fail` — primes a one-shot pre-flush failure. - `buffer_has_changeset_for_test` — probes the dirty-wallets set.

The atomic check-and-rename closes the TOCTOU window; `AlreadyExists` maps to the typed `BackupDestinationExists` so the CLI's contract stays intact. * CODE-011 — Sidecar paths in `apply_secure_permissions` and the `backup::restore_from` WAL/SHM-unlink loop are built via `OsString::push` (non-UTF-8 path bytes round-trip intact). The `set_permissions` / `remove_file` calls run unconditionally and treat `ErrorKind::NotFound` as a silent no-op, removing the `exists()` TOCTOU gate. * CODE-014 — After every `tempfile::persist*` rename in `backup::run_to` and `backup::restore_from`, the destination's parent directory is `fsync`-ed via the new `fsync_parent_dir` helper (Unix only; no-op on non-Unix). Rustdoc `# Atomicity` sections updated to mention the parent-dir fsync. * CODE-016 — `run_integrity_check` switches from `query_row` to `query_map`-collect. All diagnostic rows land in the `IntegrityCheckFailed { report }` string joined with `\n`; a mid-stream `SqliteFailure` (DatabaseCorrupt) is treated as end-of-stream when at least one row arrived (and appended as a marker), preserving the existing `atom_013` semantics. * CODE-019 — `backup::prune` now increments `kept` on a `remove_file` failure (the file is still on disk). Documented the invariant `kept + removed.len() == total_eligible` and the `failed_removals ⊆ kept` subset relationship on `PruneReport`. Tests: * TC-CODE-009-a/b — atomic overwrite refusal + Io variant mapping (`sqlite_backup_restore.rs`). * TC-CODE-011-a/b/c — non-UTF-8 sidecar chmod, missing-sidecar Ok path, source-level regression for both call sites (`sqlite_permissions.rs`). * TC-CODE-014-a/b — source-level fsync invocation count + rustdoc mention assertions (`sqlite_backup_restore.rs`). * TC-CODE-016-a — multi-page corruption yields a multi-line diagnostic report (`sqlite_open_integrity_check.rs`). * TC-CODE-019-a — chmod-locked prune dir produces `kept + removed == total` with `failed_removals` populated (`sqlite_backup_restore.rs`). T-010 fsync is verified at the source level (regression-grade test asserting `fsync_parent_dir(` appears in `backup.rs` at least three times — definition + run_to + restore_from). A real crash-durability harness is impractical in unit-test scope; the rustdoc + source-level checks pin the contract.

Without the feature the bare crate ships only `thiserror`, `tracing` and `hex` (20 lines of cargo tree -e normal, down from 1124 with default features), so embedders that only want the future `SecretStore` submodule no longer transitively pull `platform-wallet` -> `dpp`/`drive`/`dashcore`. Add `tests/feature_flag_build.rs` as a TC-CODE-020-1 source-level pin so a future contributor flipping the manifest back to unconditional deps trips a unit test instead of only the bare-build CI gate.

Callers (`open`, `count_pending`, `restore_from` source + staged) now share one implementation; the `assert_schema_version_supported` table-presence check piggy-backs on the same helper. Adds TC-CODE-027-1 (in-module unit test): helper returns false on a fresh in-memory DB and true once the table is created.

Five `#[tokio::test]`s exercise a real `PlatformWalletManager` (consumer side from `rs-platform-wallet`) against a real `SqlitePersister` (this crate) so every consumer↔ persister contract drift now fails CI instead of slipping through: * TC-CODE-008-1 — register_wallet → drop → reopen: wallet_metadata + account_registrations + account_address_pools survive. * TC-CODE-008-2 — platform_addresses round-trip through persister.store + list_per_wallet across reopen. * TC-CODE-008-3 — identity_keys + token_balances round-trip under a registered (wallet, identity) pair; regression guard for CODE-002 (sentinel WalletId::default() FK violation). * TC-CODE-008-4 — remove_wallet cascades through storage for the removed wallet but leaves the surviving sibling untouched; regression guard for CODE-003 (remove_wallet never propagated to disk). * TC-CODE-008-5 — boot the manager twice over the same DB; the persisted wallets are still on disk after a clean reopen + a second load_from_persistor() pass; regression guard for CODE-001. Per user direction ("If possible, put it into persister crate") the test lives here so the dev-dep cycle stays one-way: `platform-wallet` ships no dependency on `platform-wallet-storage`, while the storage crate is free to pull `platform-wallet` into `[dev-dependencies]` for integration coverage. Dev-deps added: `dash-sdk` with `mocks` + `wallet` features (needed by `SdkBuilder::new_mock().build()` for the manager) and a direct `tokio` so `#[tokio::test]` resolves the macro by name.

That defeats the purpose of the wallet-aware path (`register_identity_with_wallet`) and breaks the `wallet_metadata → identities → token_balances` cascade for any token balance learned through this FFI. This commit: * Adds a required `wallet_id_ptr` parameter (32 bytes) to the FFI entry point, rejecting null with `ErrorNullPointer` and the all-zero sentinel with `ErrorInvalidParameter`. * Routes to `register_identity_with_wallet(identity_id, Some(wallet_id), token_ids)` so the recorded parent wallet flows through every subsequent `persister.store(wallet_id, …)` call. * Updates the Swift wrapper `registerIdentityForTokenSync` to take the new `walletId: Data` argument, validate length on the Swift side, and marshal the buffer through the new FFI parameter. * Updates the SwiftExampleApp caller to source the parent wallet from `identity.wallet?.walletId`, skipping the registration (and the display-only fetch still works) when the identity is out-of-wallet. * Updates the doc-comment usage example in `TokenActions.swift`. BREAKING CHANGE: the C ABI for `platform_wallet_manager_identity_sync_register_identity` gains a new `wallet_id_ptr` parameter between `identity_id_ptr` and `token_ids_ptr`. Swift callers must pass the parent wallet id.

Now that the PROJ-001 consumer-side wiring has been reverted from this PR (kept for the follow-up consolidated PR), the test no longer compiles. Other storage-crate-internal round-trip coverage (sqlite_persist_roundtrip, sqlite_load_reconstruction, etc.) remains.
