fix(platform-wallet): commit wallet events off the async runtime#4370romchornyi wants to merge 7 commits into
Conversation
`run_wallet_event_adapter` called `commit_batch` — and through it `persister.store()` — inline on the tokio worker driving it. `store()` is synchronous, and for the SQLite backend commits a real transaction per call; its own trait docs say so, and warn that a slow write blocks every other wallet accessor for its duration. What they do not say, because until now it was not true, is that it also blocks the runtime those accessors run on. Field evidence from a testnet restore of a 6663-transaction wallet: - drains coalesced into ever larger, ever rarer batches — folded 1 → 47 → 164 → 512, with gaps of 42s, 144s and finally 1109s between them; - the metrics tick covering the 512-event drain reported `busy_ratio=1106 mean_poll_us=1397886` — a 1.4s mean poll on a runtime that read 24µs one second later; - `Blocks: last_activity: 549s` at the same moment, so the SPV managers sharing that runtime were starved, not idle; - the durable watermark topped out at height 2179999 against a chain tip of 2520064 and never caught up, so the home timeline — which only advances when a batch lands — showed roughly a third of the history ten minutes after core sync reported 100%. The commit now runs on `spawn_blocking`. The handle is awaited rather than raced against `cancel`: a store that has started must finish, and dropping the handle would not stop the thread in any case — shutdown is observed at the next `recv`. `AdapterFaultState` and the freeze latch move behind an `Arc<Mutex<..>>` and an `Arc<AtomicBool>` rather than being moved into the closure by value. That is deliberate: if the commit thread ever panicked, moving them would lose a wallet's frozen watermark, which would un-freeze a wallet whose verification had failed — the one outcome the fail-closed guard exists to prevent. The lock is uncontended by construction (one drain commits at a time, and this task is the only writer). A panicking commit thread is now reported and the drain skipped, rather than taking the adapter down with it. cargo test -p platform-wallet --lib # 662 passed cargo clippy --all-targets + fmt # clean

Preliminary review — Codex only
Moving synchronous persistence into spawn_blocking correctly prevents wallet commits from parking Tokio workers, but the new panic branch continues after consuming a batch whose persistence outcome is unknown, allowing a later watermark to advance past missing rows. The adapter must fail closed after a commit panic, and the off-runtime boundary should have deterministic regression coverage.

- [BLOCKING] packages/rs-platform-wallet/src/changeset/core_bridge.rs:409-420: Continuing after a commit panic can advance the watermark past lost rows
`commit_batch` consumes the folded batch and calls `store()` for each wallet. If `store()` panics before its outcome is known, unwinding bypasses the `Err` arm that calls `fault_wallet`, drops the remainder of the consumed batch, and returns a `JoinError`. This branch then continues with an unaffected fault state, so a later event for the same wallet can successfully persist a higher `synced_height` even though rows from the panicked batch may be absent. That violates the adapter's fail-closed invariant; before this PR, the panic terminated the adapter and prevented later watermark advancement. Stop the adapter and latch `sync_fault`, or capture every batch wallet ID before moving the batch and fault all of them before continuing.
- [SUGGESTION] packages/rs-platform-wallet/src/changeset/core_bridge.rs:388-407: The off-runtime persistence boundary has no regression test
The existing `ProbePersister` returns immediately and checks only persistence outcomes. Those tests still pass if `commit_batch` is moved back inline onto the Tokio worker, so they do not protect the primary behavior introduced by this PR. Add a controllably blocking persister and run the adapter on a current-thread or single-worker runtime, then verify that another future makes progress while `store()` remains blocked. The fixture should also cover a panicking store and assert that no later store for the affected wallet carries `synced_height`.
… panics Moving the commit to `spawn_blocking` quietly weakened the fail-closed rule, and both reviewers caught it. Before the move, a panic inside `store()` unwound the adapter task itself. That was violent, but it was safe in one specific way: the writer was gone, so no later batch could persist a higher `synced_height` for a wallet whose rows had just been lost. `spawn_blocking` turns the same panic into a recoverable `JoinError`, and the branch I wrote logged it and carried on — leaving the fault state untouched, so the very next batch could advance the watermark past rows of unknown fate. That is exactly the hole #4069 closed. The wallet ids are now captured before the batch moves into the closure, and a `JoinError` faults every one of them. Per-wallet rather than stopping the adapter, matching what a rejected `store()` already does: a wallet whose commit is in doubt freezes, its siblings keep syncing, and the process stays alive — which is the point of moving the commit off the runtime in the first place. `ProbePersister` gained a `panic_next` mode, and the new test asserts all three halves of the contract: the hard-fault signal is raised, the adapter survives, and no later store for that wallet carries a `synced_height`. The wait for the signal is bounded. An unbounded spin would have wedged CI with no diagnosis on a regression rather than failing it — verified by removing the fault path, where the test now fails in 5s with "a panicked commit must raise the hard-fault signal" instead of hanging. cargo test -p platform-wallet --lib # 663 passed cargo clippy --all-targets + cargo fmt --check # clean

Final validation — Codex/Sol only (Phase 2 disabled)
The current head correctly restores the fail-closed watermark invariant after a commit-thread panic, so the prior blocking issue is fixed. Two non-blocking gaps remain: the primary off-runtime behavior lacks a direct progress regression test, and panic recovery unnecessarily freezes wallets whose stores already completed successfully.

(existing thread: https://github.com/dashpay/platform/pull/4370#discussion_r3758900980)
The new panic test verifies panic isolation and fail-closed recovery, but every non-panicking `ProbePersister::store()` still returns immediately. It therefore does not directly enforce the PR's primary guarantee that a slow synchronous store cannot park the Tokio worker; an inline implementation with equivalent panic isolation would still pass. Add a controllably blocking persister and use a current-thread or single-worker runtime with an external watchdog/release mechanism, then assert that an unrelated future makes progress before the store is released.

Auto-resolved by the review system based on the latest commit diff. If you believe this was closed in error, reopen the thread.
…unknown Two review findings, and the first is a correction to my own fix. **The panic handler over-corrected.** `commit_batch` walks the batch serially, so a panic partitions it: wallets whose `store()` already returned are settled — accepted or rejected, and a rejection faulted them from inside. Faulting those too stripped a healthy wallet's watermark for the rest of the session over a sibling's bad batch. `commit_batch` now records each wallet as its `store()` RETURNS — after the call, so a panicking wallet never reaches the line, and a wallet the loop never got to is never recorded. What is missing from that list is exactly the set whose outcome nobody can reason about, and only those freeze. The list lives behind an `Arc<Mutex<..>>` outside the closure so it survives the panic that makes it interesting. **The off-runtime boundary now has a test that actually guards it.** Every other test here passes with `commit_batch` moved back inline, because they only assert persistence outcomes. `a_blocked_store_does_not_ park_the_runtime` runs the adapter on a single worker, parks a `store()` with a controllable gate, and requires a spawned task to still be scheduled. It is built out of `std::mpsc::recv_timeout` and `std::thread::sleep` rather than `tokio::time`, and that is not stylistic: the regression parks the runtime's only worker, and a tokio timer needs that runtime to fire. My first two attempts used async timeouts and HUNG on the regression instead of failing it, which is worse than the bug — CI burns the wall clock and reports nothing. Verified by reverting to an inline commit: the test now fails in 5s with "a blocked store must not hold the runtime's only worker: Timeout". The cross-wallet test is likewise bounded, for the same reason: a frozen wallet's watermark-only changeset collapses to nothing, so an unbounded `recv` waits forever on a regression. cargo test -p platform-wallet --lib # 665 passed cargo clippy --all-targets + cargo fmt --check # clean

Final validation — Codex/Sol only (Phase 2 disabled)
The main off-runtime persistence change is sound, and the current head fixes both previously verified gaps with direct regression coverage and per-wallet completion tracking. Two non-blocking panic-recovery issues remain: projected no-op wallets can be frozen despite having nothing to persist, and panic-induced freezes bypass the documented one-shot logcat fault marker.

- [SUGGESTION] packages/rs-platform-wallet/src/changeset/core_bridge.rs:384-392: Exclude no-op wallets from panic faulting
`batch_wallet_ids` includes every wallet that contributed an event, even when its projected `WalletBatch` is empty and `commit_batch` consequently skips `store()` at lines 555-559. This occurs, for example, when `TransactionInstantLocked` is intentionally ignored because the transaction is already chain-locked. If another wallet's store panics, an empty wallet does not appear in `settled`, regardless of whether it was skipped before the panic or ordered after it, so the panic handler freezes that healthy wallet's watermark for the remainder of the session even though it had no rows to persist. Build the panic-recovery candidate list from batches that contain persistable changes.
- [SUGGESTION] packages/rs-platform-wallet/src/changeset/core_bridge.rs:462-478: Emit the one-shot fault marker for panic-induced freezes
The panic branch calls `fault_wallet`, which raises the host-visible hard-fault latch, but reports the freeze only through `tracing::error!` and never updates `freeze_logged`. This contradicts the adapter's documented observability contract at lines 282-286: `SYNC WATERMARK FROZEN` deliberately uses the `log` facade because `tracing` may not reach Android logcat. A commit panic can therefore freeze watermarks without the operational marker, and a later rejected store can emit that supposedly one-shot marker as though it were the first fault. Route rejection and panic recovery through a shared atomic one-shot logging helper so the latch is updated immediately, including when a later store in the same blocking task panics.
…e any other Three review findings on the off-runtime commit move. **Empty batches were being frozen.** `batch_wallet_ids` took every wallet that contributed an event, but a wallet reaches the batch even when its events project to nothing — a `TransactionInstantLocked` ignored because the transaction is already chain-locked, a `SyncHeightAdvanced` for an unknown wallet. `commit_batch` skips those at the `is_empty_no_records()` gate and never calls `store()` for them, so a sibling's panic says nothing about their rows; freezing them stripped a healthy wallet's watermark for the rest of the session over someone else's bad batch. The candidate list is now built from batches that carry something to persist. The filter is deliberately conservative in one direction: `commit_batch` re-tests emptiness after `freeze_synced_height_if_faulted` has stripped a faulted wallet's watermark, so a batch that looks non-empty here can still be skipped there. That wallet is already faulted, so freezing it again costs nothing, while the opposite error — omitting a wallet whose store did run — is the hole this whole path exists to close. **A panic-induced freeze was invisible where it matters.** The branch raised the latch but reported only through `tracing`, while the documented contract is a one-shot `SYNC WATERMARK FROZEN` line through the `log` facade, because android_logger forwards `log` to logcat and `tracing` may not. It also left `freeze_logged` clear, so a later rejected store would have emitted that supposedly one-shot line as though it were the session's first fault. Both paths now go through the same marker, set with `swap` so a store panicking inside the same blocking task cannot produce it twice. **The boundary had no test.** Every existing assertion checks persistence outcomes, and all of them still pass with `commit_batch` called inline — they never touch the property this move is for. `a_blocking_store_does_not_ park_the_runtime` pins the runtime to one worker and asserts an unrelated task still runs while a store is blocked; inlined, it fails in 0.22s. Its release and verdict are driven from a plain `std::thread` on purpose: a regression parks the only worker, so neither the test body nor a `tokio::time::timeout` can run — an in-runtime deadline would hang CI rather than fail it, which is what the bounded waits elsewhere in this file exist to avoid.

The off-runtime commit boundary and fail-closed panic recovery are fundamentally sound, including the filtering of no-op and already-settled wallets. Three non-blocking issues remain: a rejection followed by a panic can emit the documented one-shot freeze marker twice, several fault-state comments omit panic-induced faults, and one blocking regression test is race-prone and duplicates a stronger test.

The same stale assertion appears in the adapter documentation around line 269, the commit-loop comment around line 366, and the watermark-guard comment around line 674.

(existing thread: https://github.com/dashpay/platform/pull/4370#discussion_r3779128332)
The panic branch now emits the log-facade marker, but the rejection and panic paths do not spend the same atomic latch immediately. `commit_batch` copies `freeze_logged` into a local `bool`; if wallet A's `store()` returns `Err`, lines 651-659 emit `SYNC WATERMARK FROZEN` and update only that local value. If a later wallet's store panics in the same drain, unwinding skips the atomic write-back at line 443, so the `swap` at line 508 observes `false` and emits the supposedly one-shot marker again. Pass the shared atomic latch into `commit_batch` and use one atomic compare-and-set or `swap` helper from both the rejection and panic paths so the first emission is recorded even if a later store unwinds the closure.

Auto-resolved by the review system based on the latest commit diff. If you believe this was closed in error, reopen the thread.
…blocking test's race Follow-up to two review points. **The one-shot marker could still fire twice.** `commit_batch` took the flag as a `&mut bool` copied out of the atomic on the way in and written back on the way out. That write-back never happens when a store panics mid-batch, so a marker already emitted for an earlier rejection in the same batch was lost, and the panic branch then announced the same freeze a second time. Both paths now take the `AtomicBool` itself and claim it with `swap`, so the flag is updated at the moment it is spent rather than when the task unwinds. **The blocking test could pass on a regression.** It spawned its sentinel before the store was observed blocked, so the runtime was free to poll that task first, set the flag while nothing was blocking, and let the test pass with `commit_batch` called inline. The sentinel is now spawned from the watcher thread, strictly after the block is observed, through a `Handle` captured beforehand; whether it runs is then only a question of the worker being free. The fixed 200 ms observation window is gone too — both waits are deadline polls, so a loaded runner costs time rather than a false verdict. Checked by inlining `commit_batch` three times in a row: fails every run, in 0.03s, against 666 passing with the change in place. Note for the reviewer: the suggestion to delete this test as a duplicate of `a_blocked_store_does_not_park_the_runtime` at lines 2638-2701 could not be applied — there is no such test on this branch, before or after these commits. This is the only blocking test in the file.

The off-runtime commit boundary and fail-closed panic recovery are sound: panic handling now excludes no-op and settled wallets, faults only persistable wallets with unknown outcomes, and shares the one-shot freeze latch with store-rejection handling. One in-scope documentation suggestion remains because several invariant comments still describe store rejection as the only fault trigger even though commit panics now fault unsettled wallets.

- [SUGGESTION] packages/rs-platform-wallet/src/changeset/core_bridge.rs:94-117: Document commit panics as a fault trigger
These invariant comments still state that a rejected `store()` is the only remaining fault trigger and that `fault_wallet` is called only after rejection. The adapter now also faults every persistable wallet whose outcome remains unknown after the blocking commit thread panics. The same stale invariant appears in the adapter documentation at lines 269-280, the commit-loop comment at lines 366-368, the watermark-guard documentation at lines 672-681, and the test comment at lines 2806-2807. Update these comments to distinguish a returned store error, which faults the wallet with a known rejection, from a commit panic, which faults each persistable wallet absent from `settled` because its outcome is unknown.
The invariant comments all still said a rejected `store()` was the only thing left that faults a wallet — true before this branch, and stale since the panic-recovery branch started faulting every persistable wallet whose outcome the commit never settled. A comment that describes an invariant the code no longer holds is worse than none: the next reader reasons from it. Updated at all five places the reviewer found — the `AdapterFaultState` docs and its two field/method comments, the adapter's fail-closed contract, the commit-loop comment, the watermark guard, and the fault test — and each now distinguishes the two cases rather than lumping them: a returned error faults a wallet whose rows are known not to be on disk, a panic faults wallets whose rows have an unknown fate. Comments only; no behaviour change. 666 tests pass.

Final validation — Codex/Sol only (Phase 2 disabled)
The production adapter correctly moves synchronous persistence off Tokio workers and preserves the fail-closed watermark invariant across commit panics. Two non-blocking test-quality issues remain: the panic suite does not exercise a persistable wallet ordered after the panicking wallet, and the off-runtime progress guarantee is covered by two nearly identical heavyweight fixtures.

- [SUGGESTION] packages/rs-platform-wallet/src/changeset/core_bridge.rs:2721-2732: Cover wallets the commit never reaches after a panic
The panic tests cover the wallet whose `store()` panics and a wallet successfully settled before that panic, but none includes a persistable wallet ordered after the panicking wallet. That case exercises the other load-bearing half of `batch_wallet_ids - settled`: unwinding drops its consumed changes before `store()` is attempted, so panic recovery must fault it before a later watermark can advance. A regression that faults only the directly panicking wallet would pass the current tests. Add a third wallet whose ID sorts after `doomed`, include it in the same drain, and verify that a later record-bearing store for it has `synced_height == None`. Also correct the opening comment: wallets the commit never reached must be faulted; only wallets whose stores already returned are spared.
- [SUGGESTION] packages/rs-platform-wallet/src/changeset/core_bridge.rs:2471-2576: Remove the duplicate off-runtime progress test
`a_blocking_store_does_not_park_the_runtime` and the later `a_blocked_store_does_not_park_the_runtime` enforce the same guarantee with a single-worker Tokio runtime, a controllably blocked synchronous `store()`, an externally scheduled sentinel, and an out-of-runtime deadline and release mechanism. Both are now deterministic, but retaining both duplicates a heavyweight thread/runtime fixture and leaves two tests to maintain as the adapter evolves. Their comments also each claim that no other test covers the behavior. Keep the later plain `#[test]` version, which explicitly owns the runtime and expresses the discriminator more directly, and remove this duplicate.

Resolved in 75ac76c — Cover wallets the commit never reaches after a panic no longer present.
Auto-resolved by the review system based on the latest commit diff. If you believe this was closed in error, reopen the thread.
Two review points, and the first one corrects a claim I made in an earlier commit message on this branch. **The duplicate off-runtime test was real.** I said no such test existed and skipped the suggestion; the check behind that was `grep "async fn a_block"`, and `a_blocked_store_does_not_park_the_runtime` is a plain `fn` that owns its runtime, so it never matched. It has been here since `4e5a1939b`, and it is the better of the two — explicit runtime, `std` primitives, and it states the discriminator directly. Mine is removed. **The panic tests had a hole.** They covered the wallet whose `store()` panicked and a wallet settled before it, but not a persistable wallet ordered after the panic. That is the other half of what `batch_wallet_ids - settled` computes: unwinding drops such a wallet's consumed changes before `store()` is attempted, so nothing knows whether its rows landed, and it must freeze. A handler faulting only the direct casualty passed every existing assertion. The test now drains three wallets in one batch — settled, panicking, and never-reached — and requires the third to be frozen too. Checked by truncating the unsettled set to one entry: fails on exactly that assertion. The opening comment claimed the test was about wallets the panic "did not reach" being spared, which is backwards for that half, and now describes both sides. 665 tests pass.

run_wallet_event_adaptercalledcommit_batch— and through itpersister.store()— inline on the tokio worker driving it.store()is synchronous and, for the SQLite backend, commits a real transaction per call. Its own trait docs (traits.rs:200-206, 263-267) already warn that a slow write blocks every other wallet accessor for its duration; what they do not say, because until now it was not true, is that it also blocks the runtime those accessors run on.Found while investigating a user report that a restored wallet's transaction history appears only in large, minutes-apart jumps long after Core sync reports 100%.
Evidence from a testnet restore of a 6663-transaction wallet (52k-line session log):
folded1 → 47 → 164 → 512 (theADAPTER_STORE_BATCH_LIMITceiling), with gaps of 42s, 144s and finally 1109s between them.Blocks: … last_activity: 549sat the same moment — the SPV managers sharing that runtime were starved, not idle.The escalating
foldedcounts are the symptom, not the cause: events pile up in the channel because the previous drain's synchronousstore()is still holding a worker.What was done?
commit_batchnow runs ontokio::task::spawn_blocking.The handle is awaited rather than raced against
cancel. A store that has started must be allowed to finish, and dropping aspawn_blockinghandle does not stop the thread in any case. Shutdown is observed at the nextrecv, which is where the loop already handles it.AdapterFaultStateand the freeze latch move behindArc<Mutex<..>>/Arc<AtomicBool>instead of being moved into the closure by value. This is the part worth reviewing: moving them would mean a panicking commit thread loses a wallet's frozen watermark — un-freezing a wallet whose verification had failed, which is the single outcome the fail-closed guard exists to prevent. The lock is uncontended by construction (this task is the only writer, and one drain commits at a time), so it carries state rather than arbitrating access.A panicking commit thread is now reported and its drain skipped, rather than taking the adapter down with it.
Not done here
Nothing about batch sizing, the channel, or
ADAPTER_STORE_BATCH_LIMIT. With the blocking call off the runtime the coalescing behaves as designed; tuning it before re-measuring would be guessing.How Has This Been Tested?
Not covered: no test reproduces the stall. Doing so needs a persister whose
store()blocks for a controllable duration plus assertions on runtime poll latency — worth adding, but it would not have caught this class of bug by construction, only this instance of it. The change is behaviour-preserving for the commit itself: the samecommit_batch, the same inputs, the same diagnostics line.A before/after restore on device is the measurement that matters, and I have the "before" trace above to compare against.
