feat(swift-sdk): add async off-main wallet manager shutdown - #4469
Merged
Conversation
… metrics Replace the synchronous deinit teardown (5x sync stop + destroy, which block_on's the Rust lifecycle shutdown on whatever thread ARC releases on — historically the main thread, freezing the UI for up to ~45s on a network switch) with an explicit, idempotent shutdown() that takes the FFI handle exactly once on the main actor and runs the same teardown sequence on a dedicated serial queue. deinit becomes an emergency fire-and-forget fallback. Returns per-step FFI codes + timings so the host can log switch telemetry. Internal test seam (makeForTesting + nativeTeardownOverride) with a 7-case XCTest suite. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> (cherry picked from commit 740bd84fd286ead71644609e786652632a3b6665)

409-416: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick winDo not cache the no-op shutdown result.
The NULL-handle path stores a no-op task in
shutdownTask.configure()only requires!isConfigured, so a manager can be shut down before configuration and configured afterwards. A latershutdown()then returns the cached no-op at Line 407 and skips the native teardown of the live handle. Thedeinitfallback still destroys the handle, so teardown becomes non-deterministic instead of explicit.Return the no-op metrics without recording the task.

Addressed the shutdown-before-configure edge case in 07ff21b. A NULL_HANDLE no-op is no longer cached, so a manager configured later still tears down its live handle. Added a regression test covering no-op shutdown → late configuration → real teardown. |

Preliminary review — Codex only
The off-main, take-once teardown is otherwise coherent, but a manager can be configured again after a completed shutdown, after which the permanently cached shutdown task prevents explicit teardown of the new Rust handle. The DPNS callback also lacks the generation guard added to the other asynchronous sync callbacks, and the tests bypass the production six-call teardown body despite claiming ordering and metrics coverage.
Source: Codex reviewer evidence (general, FFI engineer, and security auditor lanes); Claude Agent SDK final verifier. Exact backend model IDs were not present in the supplied evidence. openclaw-agent/cliproxy/gpt-5.6-sol is orchestration-only and is not reviewer evidence.
Validated blockers were found in the Codex precheck. Opus is deferred until a fresh Codex revalidation clears the blocker gate.

In `packages/swift-sdk/Sources/SwiftDashSDK/PlatformWallet/PlatformWalletManager.swift`:
- [BLOCKING] packages/swift-sdk/Sources/SwiftDashSDK/PlatformWallet/PlatformWalletManager.swift:407-408: Cached shutdown result can strand a subsequently configured handle
A real shutdown permanently stores `shutdownTask` while setting `isConfigured` to `false`. The normal `configure(sdk:...)` precondition therefore permits configuration again, and the public raw-pointer overload has no shutdown-state guard. That configuration creates a new Rust registry entry and transfers retained callback contexts, but every subsequent `shutdown()` returns the old task here without consuming or destroying the new handle. The manager's explicit shutdown contract is then broken, and the new native manager and workers remain live until the emergency `deinit` fallback. Reject both configuration paths whenever `shutdownTask` is non-nil; the intended shutdown-before-first-configuration flow remains valid because the NULL-handle no-op deliberately leaves `shutdownTask` nil. Add a regression test covering real shutdown followed by attempted configuration.
- [SUGGESTION] packages/swift-sdk/Sources/SwiftDashSDK/PlatformWallet/PlatformWalletManager.swift:427-429: DPNS callbacks can cross back into Swift after shutdown
Shutdown invalidates shielded and platform-address callback generations, but not the DPNS completion callback. `dpnsMarketplaceSyncCompletedCallback` copies its event and unconditionally enqueues a `MainActor` task, so Rust can finish dispatching the callback while teardown is in progress even though the queued Swift task has not run. Because `shutdown()` suspends the main actor while awaiting native teardown, that task can subsequently publish `lastDpnsSyncEvent` after the manager has been marked unconfigured or after shutdown completes. Add a DPNS generation counter, snapshot it in the FFI trampoline, bump it here during shutdown, and reject mismatched generations in `handleDpnsSyncCompleted`, matching the shielded and platform-address paths.
In `packages/swift-sdk/SwiftTests/SwiftDashSDKTests/PlatformWalletShutdownTests.swift`:
- [SUGGESTION] packages/swift-sdk/SwiftTests/SwiftDashSDKTests/PlatformWalletShutdownTests.swift:204-221: Production teardown ordering and metrics are bypassed by the test seam
`nativeTeardownOverride` replaces `performNativeTeardown(_:)` wholesale, and this test constructs the expected steps and result codes itself. The suite therefore verifies only that `shutdown()` returns injected metrics; it would continue to pass if the production body omitted `destroy`, reordered the five stop calls, mislabeled a step, or associated an FFI result with the wrong step. Since ordered execution and per-call metrics are explicit guarantees of this PR, inject the individual native functions through a function table or runner seam and execute the real production orchestration in the test, asserting all six invocations and their result-to-step mapping.

Final validation — Codex/Sol only (Phase 2 disabled)
At exact head f50f77c, all three prior findings are fixed: configuration is terminal after a real shutdown, DPNS callbacks are generation-guarded, and tests exercise the production teardown orchestration through per-call injection. The focused Swift shutdown and DPNS suites compiled and passed locally: 20 tests, 0 failures.
Source: Codex reviewer evidence from codex-general, codex-ffi-engineer, and codex-rust-quality (exact backend model IDs were not supplied); Claude Agent SDK final verifier (exact backend model ID was not supplied). openclaw-agent/cliproxy/gpt-5.6-sol is orchestration-only and not reviewer evidence.
Validated zero-blocker Codex/Sol precheck evidence was promoted to final because Phase 2 (Sonnet/Opus) is temporarily disabled. This is Codex/Sol-only final validation, not Codex + Sonnet/Opus coverage.

Brings the branch up to date with upstream after #4457, #4465, #4399, #4467, #4257, #4382, #4423, #4463, #4377, #4440, #4472, #4477, #4470, and #4469 landed on v4.2-dev (base tip 1e26927). One conflict, in packages/kotlin-sdk/.../dashsdk/wallet/ManagedCoreWallet.kt: upstream #4377 inserts a new setGapLimit() immediately above broadcastTransaction(), while this branch rewrites that same broadcastTransaction() — expanding its KDoc to document the age-guard refusal and wrapping the body in mapNativeErrors { } so the native stale-broadcast error (code 34) surfaces typed. The two edits are additive and independent, so resolved as the union: setGapLimit() kept verbatim from upstream, broadcastTransaction() kept verbatim from this branch. Three more files overlapped but auto-merged, and were verified rather than assumed: - changeset/core_bridge.rs: this branch factors the input walk into spent_outpoint()/spent_outpoints() so the in-broadcast fence and the persister's spent-set cannot disagree about which inputs count; upstream #4257 replaces the synthetic ScriptBuf::default() with the input's real locking script. Orthogonal — #4257 changes the Utxo payload, the fence's filter predicate is unchanged. Both sides' tests pass, including #4257's two new script-reconstruction tests running through this branch's refactored walk. - manager/mod.rs: upstream adds the tracked_masternodes field and its initializer; this branch's SpendObservationHandler registration and its cfg(any(test, feature = "shielded")) widening are untouched. - rs-platform-wallet-ffi/src/error.rs: upstream adds ErrorMasternodeListUnavailable = 46; this branch maps PlatformWalletError::StaleReservation onto the existing shared code 34. No discriminant or name collides. Upstream's three new PlatformWalletPersistence methods all carry default bodies, so this branch's NoopTestPersister needs no change. Verified: the merged tree is identical to origin/v4.2-dev except in exactly the 18 files this branch owns, and this branch's net delta against the new base is unchanged at +3457/-103. cargo test -p platform-wallet --lib: 784 passed, 0 failed. cargo test -p platform-wallet-ffi --lib: 278 passed, 0 failed. cargo fmt --check and cargo clippy --all-targets -D warnings: clean on both crates.

Brings the shielded-invite branch up to date with upstream v4.2-dev (#4470 active-protocol-version shielded fees, #4472 shield credits to an external Orchard recipient, #4477, #4469 swift async shutdown). One conflict, in rs-platform-wallet/src/wallet/shielded/operations.rs: both sides appended a #[cfg(test)] module at the same insertion point — this branch's foreign_claim_guard_tests (single-flight claim lifecycle guard, #4313 review finding 979bbc2fcb3c) and upstream #4472's shield_recipient_tests (resolve_shield_recipient classification). Resolved by keeping BOTH modules in full, this branch's first, each under its own #[cfg(test)]. No code from either side dropped or altered. The FFI error-code seam needed no hand-merge: upstream #4469's ErrorMasternodeListUnavailable = 46 was allocated explicitly around this branch's 43/44/45 shielded-invite trio. Verified: cargo check -p platform-wallet --features shielded and platform-wallet-ffi --all-features clean; cargo test platform-wallet --features shielded --lib = 984 passed / 1 failed — shield_input_selection_tests::regression_reports_max_from_usable_suffix _not_total_account_balance, proven PRE-EXISTING on unmerged origin/v4.2-dev (1e26927): upstream's versioned-fee change dropped shield_fee_reserve_credits(LATEST) below the test's seeded 297_264_780 leading balance; the unmerged PR head passes it. platform-wallet-ffi = 330 passed / 0 failed; rs-unified-sdk-jni = 37 passed / 0 failed; kotlin-sdk :sdk:test = 353 tests x debug+release, 0 failures.

…4470 active-version fees + #4472 shield-to-recipient) Reconciles the branch with the active-protocol-version fee estimation (#4470), the shield-to-external-Orchard-recipient operation (#4472), the block-time truncation fix (#4477) and the async wallet-manager shutdown (#4469). One textual conflict, packages/rs-platform-wallet-ffi/src/shielded_send.rs, plus one silent auto-merge hazard in the same file: - Duplicate guard helpers (auto-merged, NOT flagged by git). #4472 adopted this branch's panic-guard split verbatim, so the merge kept BOTH copies of panic_payload_message / catch_panic_to_code / SPEND_PANIC_GUIDANCE / catch_spend_panic. The bodies are byte identical; this branch's copy is a strict superset (it also carries IDENTITY_CREATE_PANIC_GUIDANCE, ASSET_LOCK_FUNDING_PANIC_GUIDANCE and SEED_POOL_PANIC_GUIDANCE for its non-spend guard call sites). Kept this branch's block, deleted upstream's duplicate, and widened the SPEND_PANIC_GUIDANCE doc to name shield-to-recipient among the operations it covers. - The shared guard tests. Upstream re-labelled the operation string in catch_spend_panic_maps_a_panic_to_the_unconfirmed_contract from "shielded multi-output transfer" to "shielded shield to recipient" and dropped the #4312 review-finding citation. Kept this branch's labels and citation (one test name, one definition); the guard the new export uses is exercised either way, and this branch's catch_panic_to_code_carries_the_per_operation_contract and max_recipients_matches_the_effective_action_ceiling tests survive. Everything else interleaved cleanly and was verified rather than assumed: this branch's four catch_pre_broadcast_panic sites (unshield / transfer / transfer_multi / withdraw) and catch_pre_broadcast_panic_async sit outside shield(), which is the only function #4472 rewrote in operations.rs (into shield + shield_to + resolve_shield_recipient), so both survive whole. No FFI export and no test was lost from either side: the merged shielded_send.rs gains exactly platform_wallet_manager_shielded_shield_to_recipient, and the only retired test is upstream's own rename of estimate_fee_matches_observed_onchain_values_for_2_actions into its protocol-13 / protocol-14 / manager-handle triple. No fee numbers needed recalibrating, and the output-aware predictor needed no change to adopt #4470's active-version sourcing: it is already version-parameterized end to end and every production call site feeds it sdk.version() -- the same network-tracked accessor #4470 switched the FFI estimator to. ShieldedFeeKind::compute takes &PlatformVersion (note_selection.rs:56); select_notes_with_fee and select_notes_for_denomination thread it through (:197-207, :288-311); reserve_unspent_notes and its denomination sibling pass sdk.version() (operations.rs:2329, :2362), as do shield's fee carve (:593) and every builder call (:647, :887, :1081, :1285, :1495, :1708, :1907). PlatformVersion::latest() survives only in #[cfg(test)] fixtures and in MAX_SHIELDED_TRANSFER_RECIPIENTS's ceiling assertion -- a structural action bound, not a fee, and version-invariant in any case (max_shielded_transition_actions = 16 and max_state_transition_size = 20480 in every system_limits version, so protocol 13 and 14 yield the same ceiling of 6). The shield_input_selection fixture survives because it derives: reserve() calls shield_fee_reserve_credits(LATEST_PLATFORM_VERSION) (platform_wallet.rs:2203) rather than pinning a literal, so it tracks any fee-constant movement automatically. #4470 did not touch reserves at all. Verified: cargo fmt --check and cargo clippy clean on platform-wallet, platform-wallet-ffi, dpp and rs-unified-sdk-jni. Tests: 942 passed platform-wallet (--features shielded --lib), including all four *_prover_panic_releases_the_note_reservation tests, all twelve shield_input_selection_tests and #4472's four shield_recipient_tests; 294 passed platform-wallet-ffi (--features shielded --lib), including #4470's estimate_fee protocol-13 / protocol-14 / manager-handle / unknown-handle tests; 241 passed dpp shielded (--all-features --lib shielded), including all three wire_cost_measured_tests. 0 failures.

Issue being fixed or feature implemented
PlatformWalletManager previously performed five native sync stops plus destroy synchronously from deinit. When ARC released the last manager reference on the main thread during a network switch, a delayed Rust shutdown could freeze the iOS UI for tens of seconds.
What was done?
How Has This Been Tested?
Breaking Changes
None. The new API is additive; deinit retains a safe fallback.
