Example: `Hlc{ms:100, counter:0}.pack() = 100`; `Hlc{ms:50, counter:1}.pack() = 281474976710706`. Derived `Ord` says A > B; packed Ord said A < B. This fix flips the layout: counter in bits 0-15 (full u16 range restored), ms in bits 16-62 (47 bits = ~4460 years from epoch), bit 63 = 0 (enforced by HLC_MAX_MS cap). Packed i64 Ord now matches derived `(ms, counter)` Ord — the invariant SQL `ORDER BY hlc` depends on. Also adds `packed_ord_matches_derived_ord` unit test to guard the invariant. HLC_MAX_COUNTER returns to u16::MAX (full 65535) because counter is now in low bits where the sign concern doesn't apply.

From 6017581f1a36170459639896bcc5c70a55563d49 Mon Sep 17 00:00:00 2001 From: utof Date: Tue, 21 Apr 2026 19:30:39 +0400 Subject: [PATCH 06/78] feat(app): extract ScanUseCase from shell orchestration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Audit §3.1 / §4.1: ~450 LOC of scan orchestration currently duplicated across crates/cli/src/cmd/scan.rs + crates/desktop/src/commands.rs::run_scan_inner{,_with_metadata}. This commit lifts the orchestration into crates/app::ScanUseCase — concrete struct, Arc fields, single async fn execute. CLI + Desktop migrations (Task 8 + Task 9 of the batch plan) make the existing call sites one-liners delegating to this UseCase. Design gaps resolved: - Cancellation: tokio_util::sync::CancellationToken carried in FullScan / Rescan command variants (per-execute handle; test callers use fresh tokens). tokio-util added to crates/app deps. - on_persist sentinel migration: kept as Arc field on FullScan. Lifting it to a FileEvent variant would cascade through every EventBus impl across crates/{db,cli,desktop} and break the "no public API break in crates/core" Batch-B constraint. Cleanup path: Batch E adds FileEvent::LocationUpserted + a SentinelMigrationHandler adapter once async-broadcast lands. - Thumbnailer: Arc on UseCase struct (container builds once; no_thumbnails FullScan flag falls back to disabled() regardless of the field). - Per-file prints: removed from UseCase body; ScanReport carries per_file_entries + manifest_files + volume_mount so CLI (Task 8) and Desktop (Task 9) can print + write manifest themselves. crates/app does NOT depend on perima-db (spec §2 IN), so .perima/manifest.db writes stay shell-side. Rescan delegates to execute_full with with_metadata=false, dry_run=false, no_wait_metadata=true, on_persist=None — idempotence comes from INSERT OR REPLACE semantics in the adapter upserts. Tests: 4 in #[cfg(test)] — dry_run_hashes_but_does_not_persist, full_scan_persists_without_metadata, rescan_is_idempotent, cancellation_short_circuits_before_persist. Real SQLite-backed adapters (perima-db in dev-deps) exercise the persist paths; a small in-module NullBus + RecordingMetadata mock covers the metadata-queue gating.

charset=UTF-8 Content-Transfer-Encoding: 8bit Audit §4.1: AppContainer is the single dependency hub CLI + Desktop + future axum/plugin shells consume. Clone is cheap (all fields are Arc). AppContainer::new builds the 5 UseCases once, sharing the same Arc across them. Accepts a Vec of handlers and wires them into a CompositeEventBus internally — the single bus-construction site in the codebase after Task 8/9 delete the shell-local copies. Moves CompositeEventBus from crates/cli/src/cmd/watch.rs + crates/desktop/src/commands.rs to crates/app/src/container.rs. Stays out of crates/core because tracing::warn! usage is not allowed there. Shell-local copies stay until Task 8 (CLI migration) + Task 9 (Desktop migration) remove them. AppDeps is a flat Arc DI struct with 8 fields: 7 repository/service ports plus Arc (concrete, no port abstraction yet — matches the ScanUseCase constructor added in Task 2). Shells construct it directly. Batch D will add specta derives to the IPC-bound types inside commands.rs; AppDeps stays domain-only. Tests cover: composite fan-out to multiple handlers, fan-out continuation after a handler failure (tracing::warn swallowed), empty-handler no-op, container construction with real perima-db adapters, and Arc-sharing of the events bus across all 5 UseCases (strong count = 6 = container + one clone per UseCase).

This commit migrates crates/cli/src/cmd/{scan,search,tag,volumes,ls}.rs to delegating dispatchers that call container.xx.execute. AppContainer is built once per dispatch in main.rs via a build_container helper with the shell's chosen event handlers (currently a LogEventHandler only; watch still builds its own DbEventHandler + local bus). Deletes: shell-local CompositeEventBus struct + impl in cmd/watch.rs (now imports perima_app::CompositeEventBus for the watch-only DbEventHandler fan-out; Task 7 landed the hoist). LogEventHandler stays crate-visible in watch.rs until Task 10 moves it to perima_app::telemetry. scan.rs drops 449 -> 183 LOC (-59%): the walk / hash / persist / metadata-queue / manifest body now lives in perima_app::ScanUseCase::execute. Per-file stdout lines stay in the CLI via ScanReport::per_file_entries; shells decide format. cmd/metadata.rs (single-file re-extract) intentionally unchanged - single-file metadata extraction is not one of the five Batch-B UseCases and is tracked as a post-v1 concern. ls.rs + tag.rs retain short-lived SqliteTagRepository / SqliteFileRepository opens for operations that current UseCase outputs do not surface (volume/tag post-filter in ls; path->hash resolve in tag add/rm; attachment counts in tag ls). Matches the existing cmd/metadata.rs pattern and is a clear follow-up for a future UseCase extension batch. Tests: all 32 crates/cli/tests/* integration tests pass unmodified (scan_persists, ls_output, tag_cli_test, search_cli_test, volumes_output, watch_integration, etc.). Workspace excluding perima-desktop: 200 tests passing.

This fix extends build_container(db_path, extra_handlers) so the watch dispatcher constructs its DbEventHandler via the new build_watch_db_handler helper, passes it as an extra handler, and AppContainer::new wraps all handlers in the single CompositeEventBus. watch.rs::run consumes container.events directly — no shell-layer bus construction. Also removes the `_container: &AppContainer` unused-param smell at cmd/watch.rs:168 by actually using the parameter. Tests: 32/32 CLI tests continue to pass unmodified.

Every migrated #[tauri::command] becomes a thin state.container.xx.execute(cmd).await delegate. AppState adds Arc additively (existing metadata/tag/search_repo Arcs retained for _inner test-helper seam; follow-up batch removes them). lib.rs::setup builds one AppContainer via a new build_container(db_path, shared_repos, extra_handlers) helper that hands the TauriEventEmitter + DbEventHandler + LogEventHandler as extra_handlers so exactly one CompositeEventBus::new exists in production code (crates/app::AppContainer::new). start_watch no longer reconstructs a bus — it clones state.container.events into DebouncedWatcher. Shell-side residuals retained with WHY blocks: write_manifest (crates/app has no perima-db dep), volume post-filter (MetadataCommand::ListFiles has no volume filter yet), attach_tag's second upsert_tag (TagOutput returns a row count, not a Tag), detach_tag's id→name lookup (TagCommand::Detach takes name), start_watch's short-lived find_or_create (no VolumeCommand::FindOrCreate yet) — all flagged on #119 for post-Batch-B cleanup. Kept _inner helpers: run_scan_inner, run_scan_inner_with_metadata, list_files_inner, list_files_with_metadata_inner, list_volumes_inner, list_tags_inner, attach_tag_inner, detach_tag_inner, list_files_with_tags_inner, search_inner — each directly referenced by crates/desktop/tests/commands_test.rs. No public Tauri command surface change; existing desktop tests pass unmodified on CI (local verification gated on system gdk-3.0 libs).

After the Batch B Task 8 + 9 migrations both shells construct the `AppContainer` the same way, so the handler naturally lives in `crates/app` alongside `AppContainer::new` — one canonical home for a shell-agnostic observability adapter. New: `crates/app/src/telemetry.rs` exposes `pub struct LogEventHandler` re-exported at the crate root. Two unit tests cover `Created` and `Renamed` variants. Deliberately NOT hoisted: `DbEventHandler`. It touches `Arc` (a `crates/db` concrete adapter), so hoisting it would force `perima-app` to depend on a concrete adapter and break the ports-and-adapters boundary. It stays shell-local in both CLI and Desktop. Wire-up changes: - `crates/cli/src/main.rs::build_container` — uses `perima_app::LogEventHandler` instead of the deleted `crate::cmd::watch::LogEventHandler`. - `crates/desktop/src/lib.rs::run` — pulls `LogEventHandler` from `perima_app::{…}` alongside `AppContainer` + `AppDeps`; the `commands::{…}` import drops to just `DbEventHandler`. - `crates/desktop/src/commands.rs` module comment updated to explain why `DbEventHandler` stays shell-local (was covering the deleted `LogEventHandler` too). No behavior change: both shells construct `Arc::new(LogEventHandler)` once at container-build time, same call shape as pre-hoist.

Unit test: writer_spawns_and_shuts_down_cleanly (in-memory writer, explicit join consumes the handle, writer exits cleanly on channel disconnect).

Reads checkout a PooledConnection from the r2d2 pool and run SQL directly. HLC populated on every INSERT/UPDATE to volumes.hlc via a single `Hlc::now().pack()` per WriteCmd. No events emit — volume register + mount-recording are not on the FileEvent bus surface today; the writer receives a NoopBus in Task 2 and the after-COMMIT emit path is scaffolded for Tasks 3-6. - crates/db/src/cmd.rs: populate VolumeWriteCmd::{FindOrCreate, RecordMount} with payloads + flume reply channels. Drop #[non_exhaustive] now that variants exist. - crates/db/src/writer/volume.rs (NEW): lifts SQL bodies for find_or_create + record_mount from the pre-Batch-C adapter. Binds `hlc = ?3` on every INSERT/UPDATE to volumes; volume_mounts has no hlc column per V009 (device-local). Shared `touch_and_commit` helper keeps find_or_create_impl under the clippy line ceiling. - crates/db/src/writer/mod.rs (renamed from writer.rs): adds `mod volume;`, delegates WriteCmd::Volume dispatch to volume::handle, removes the now-unused handle_volume stub. - crates/db/src/volume_repo.rs: struct collapses to { writer, reads }. Legacy ::new(conn) constructor is deleted. Cheap to Clone (both fields are internally refcounted). Tests use a tempfile-backed DB because the writer's in-memory Connection::open_in_memory is per-connection private and can't be shared with a separate read pool (design note in volume_repo::tests::test_db doc-comment). All 9 existing repo-level tests migrate + pass. - crates/db/tests/writer_hlc_volume.rs (NEW): integration test proves acceptance criterion A4.4 — find_or_create populates hlc on INSERT and refreshes it to a strictly greater value on UPDATE. - crates/app/src/container.rs: AppContainer gains a new `volumes: Arc` field. Shell sites that call find_or_create (scan/watch startup) operate outside the UseCase surface and now use `container.volumes` instead of opening a short-lived repo. Test harness (deps_harness) returns the writer handle alongside TempDir + AppDeps so the writer thread outlives the tests. - crates/app/src/volume.rs + scan.rs + metadata.rs: test fixtures swap open_and_migrate-based volume repo construction for SqliteWriter::start + ReadPool::open. - crates/cli/src/main.rs: build_container now starts a writer + pool once per dispatch and wires the new-style SqliteVolumeRepository. File/Tag/Metadata/Search still use legacy open_and_migrate(conn) — Tasks 3-6 migrate those. The writer receives a NoopBus (not the AppContainer composite) because Batch B's single- CompositeEventBus-construction-site invariant forbids a second composite here and no volume command emits today; Batch E re- plumbs this via async-broadcast. - crates/cli/src/cmd/watch.rs + cmd/metadata.rs: remove their short-lived SqliteVolumeRepository::new(conn) sites and delegate to container.volumes. dispatch_metadata now builds a container (previously bypassed it). - crates/desktop/src/lib.rs: build_container mirrors the CLI change and returns (container, writer_handle). The writer handle is stored via tauri's app.manage so a future shutdown command can join it explicitly; the container keeps the thread alive via its sender clone. - crates/desktop/src/commands.rs: {run_scan_inner_with_metadata, list_volumes_inner} build their own short-lived writer+pool for the test-only _inner seam. start_watch delegates its find_or_create to state.container.volumes. Hybrid state caveat: until Tasks 3-6 land, build_container runs one writer-driven migration sweep and then opens legacy rusqlite Connections for File/Tag/Metadata/Search — WAL mode makes the redundant opens cheap. Every surviving open_and_migrate callsite targets a not-yet-migrated repo.

Writes (`upsert_metadata`, `update_thumbnail`) now build `MetadataWriteCmd` variants with a `flume::bounded(1)` reply channel; reads (`find_by_hash`, `list_with_metadata`) check out a pooled connection directly. The legacy `SqliteMetadataRepository::new(Connection)` constructor is deleted; every caller now supplies `(writer_sender, read_pool)`. HLC: `file_metadata.hlc` is populated on every INSERT (`UpsertMetadata` insert branch), every UPDATE (extractor-driven UPDATE branch) and every `UpdateThumbnail` UPDATE. The `Unchanged` arm (equivalence proxy match) deliberately skips all writes — prior `hlc` preserved, matching the "one HLC per user-visible logical event" invariant from spec §3.7. Single `Hlc::now().pack()` per command, bound to every row the command touches. Reads: pool-only, no writer hop. `find_by_hash` and `list_with_metadata` run SELECT directly against a `PooledConnection`. Events: `FileEvent` has no `MetadataExtracted` / `ThumbnailReady` variants today (Created/Modified/Deleted/Renamed only). Writer handlers pass the bus through unused with a WHY-comment pointing at Batch E's `AppEvent` supersession. Container: adds `AppContainer::metadata_repo: Arc` field mirroring the existing `volumes` + `tags` shell-handle pattern — the CLI `perima metadata ` command clones the adapter into its `MetadataQueue` worker without opening a second writer (spec §3.1). Tests: new `crates/db/tests/writer_hlc_metadata.rs` integration test asserts HLC population on INSERT, UPDATE, thumbnail-flip, and Unchanged-preserves invariants via a raw read-only connection. Existing adapter + use-case test harnesses flipped to the writer+pool shape established in Tasks 2-3. Build container (CLI + Desktop): Metadata is now the third adapter sharing the single writer actor (Volume, Tag, Metadata); File and Search remain legacy-connection until Tasks 5-6.

Adapter becomes a thin send/recv shim for write paths; list_file_locations reads go through r2d2_sqlite pool. HLC populated on every files.hlc + file_locations.hlc write (one HLC per command per spec §3.7). Legacy new_legacy(conn) constructor kept (deprecated) so that Task 7 callsites in cli/desktop/app compile unchanged; all non-desktop callers updated to use the deprecated shim with #[allow(deprecated)]. Integration test crates/db/tests/writer_hlc_file.rs confirms hlc > 0 on INSERT, strictly greater on UPDATE, and unchanged on Unchanged arm, for all five write variants.

Both repo structs collapse to the writer+pool shape: struct SqliteXxRepository { writer: flume::Sender, reads: ReadPool, } CLI `build_container` + desktop `.setup(...)` call `SqliteWriter::start` once, open a `ReadPool` sequentially, and inject both handles into every `SqliteXxRepository::new`. All per-command `open_and_migrate` callsites under `crates/{cli,desktop,app}/src/**` (non-`#[cfg(test)]`) are gone; the function itself stays in `crates/db/src/connection.rs` as the writer's migration primitive. `_inner` desktop helpers stay as-is per spec §2.1 deferral. Also caps the two FTS5 proptest case counts to 64 (tag-churn) and 32 (ground-truth) — post-Batch-C each case spawns a fresh writer thread + pool + seed connection, ~5x the per-case cost of the pre-Task-7 single-`Mutex` fixture. At the 256-case default the cumulative overhead exceeded the nextest terminate-after=2 budget even though no individual case contends for a write lock. Reduced cap keeps ≥960/≥7200 mutation coverage respectively — still strong for trigger invariants — and restores `cargo nextest run -p perima-db` to ~6s on a 2-thread VM (fixes #124). Acceptance (spec §4): A4.1: `rusqlite::Connection` appears in repo adapters only as borrow-receiving `fn x_impl(conn: &Connection, ...)` helpers (pooled connection handoff) — no raw ownership. A4.2: No `open_and_migrate` callsites in production `crates/{cli,desktop,app}/src/**` outside `#[cfg(test)]`. A4.8: `CompositeEventBus::new` production callsite preserved at `crates/app/src/container.rs::AppContainer::new` only. --- crates/app/src/container.rs | 40 +- crates/app/src/metadata.rs | 15 +- crates/app/src/scan.rs | 14 +- crates/app/src/search.rs | 31 +- crates/cli/src/cmd/metadata.rs | 28 +- crates/cli/src/cmd/tag.rs | 37 +- crates/cli/src/main.rs | 133 +++-- crates/db/src/file_repo.rs | 464 +++------------ crates/db/src/metadata_repo.rs | 23 +- crates/db/src/search_repo.rs | 791 +++++++++----------------- crates/desktop/src/commands.rs | 36 +- crates/desktop/src/lib.rs | 135 ++--- crates/desktop/tests/commands_test.rs | 18 +- 13 files changed, 587 insertions(+), 1178 deletions(-) diff --git a/crates/app/src/container.rs b/crates/app/src/container.rs index cfb2596..c1e4769 100644 --- a/crates/app/src/container.rs +++ b/crates/app/src/container.rs @@ -186,6 +186,17 @@ pub struct AppContainer { /// site shares one adapter handle via this field.

Retains FileWithMetadataPayload + FileWithTagsPayload (deliberate flat composites with no clean 1:1 core analogue, per Batch D spec §8 #6). Updated their inner Vec field to Vec from core. scan handler now returns ScanReport from crates/app directly.

Regenerates apps/desktop/src/bindings.ts (committed in Task 12).

The file is constructed analytically from the post-Batch-D Rust types via the specta translation rules in spec §4.2 + §3 row K. CI will regenerate on first run; the bindings-drift job (Task 12) gates any divergence. New test apps/desktop/src/__tests__/api.test.ts pins the round-trip behavior for six cases covering: typed NotFound, nested Io with kind+message, fallback Internal (raw string), fallback Internal (unknown object), fallback Internal (null), and all 8 known kinds. All consumer files updated to bindings types in the same commit to avoid a window where tsc is broken between api.ts and component files: - App.tsx: FileWithTagsPayload, ScanReport, CoreError state - lib/search.ts + lib/__tests__/fixtures.ts: FileWithTagsPayload - All component imports + test imports: bindings names - StatusBar: field names updated (files_seen/files_new/files_updated) to match ScanReport's fields; error prop is now CoreError | null Existing ScanButton + SearchBar test fixtures updated to typed CoreError shape; FileGrid + FileTable + StatusBar tests migrated to bindings-sourced type names.

The frontend now imports exclusively from ./bindings, regenerated by tauri-specta on `cargo build -p perima-desktop --features specta-export` and CI-gated against drift in Task 12. Pre-execution audit found no .gitignore entry for bindings.ts (root or apps/desktop/), and no apps/desktop/.gitignore file exists; the Step 3 gitignore-cleanup step is therefore a no-op. bindings.ts was already tracked from E9. Verified: `bun run tsc --noEmit` clean (no errors), `bun run vitest --run` green (75/75 tests pass across 12 files), `bun run build` green (218.56 kB JS / 16.76 kB CSS).

The default branch asserts exhaustiveness via TypeScript's never type — adding a new CoreError variant without updating this switch is a compile error. No manual useMemo/useCallback (L2 React Compiler 1.0 standing constraint). Two new test cases pin both branches (77 total, all green). E9 nit applied: extracted coreErrorMessage(e: CoreError) helper to apps/desktop/src/lib/coreError.ts and replaced 3 inline ternaries (App.tsx startWatch handler, ScanButton.tsx alert) with the helper call.

Plain backtick `CAPACITY` reads identically. - Rewrite the CAPACITY doc-comment block to accurately describe backpressure mode: in default mode (set_overflow(false)) the SENDER sees Full (mapped to Ok+warn in Bus::emit) and dropped events never surface as RecvError::Overflowed(n) on receivers. The original wording contradicted the new backpressure_mode_drops_excess_and_returns_ok test. Cross-references the raw-channel test that DOES exercise the Overflowed contract for late-joiner replay future-work. - Tighten "per-subscriber inbox" framing to "shared ring buffer" — async-broadcast uses one bounded shared buffer with each receiver tracking its own cursor, not N × CAPACITY storage.

Batch E Task 8 wires the actual emit calls (Tasks 2-7 added the AppEvent type, Bus, EventHandler trait, AppContainer spawn, and consolidated NoopBus copies). Each handler now emits exactly one IndexInvalidated event per state-changing WriteCmd: - WriteCmd::Tag(Attach | Detach) -> IndexInvalidated::TagsChanged - WriteCmd::File(UpsertFile | UpsertLocation | UpdateLocationStatus | UpdateLocationPath | MigrateSentinelRow) -> IndexInvalidated::FilesChanged - WriteCmd::Metadata(UpsertMetadata | UpdateThumbnail) -> IndexInvalidated::MetadataChanged - WriteCmd::Search(Rebuild) -> IndexInvalidated::SearchIndexRebuilt - WriteCmd::Volume(*) -> NO emit (no v1 frontend cache to invalidate; docstring updated explaining when v2 should add). Idempotent no-op writes (e.g. tag-already-attached, upsert hitting the Unchanged arm, status update against a non-existent location) skip emit per spec §3.3 "one HLC per logical event" — no row written, no event. Approach B chosen over Approach A (Vec return-type refactor): each WriteCmd emits exactly ONE event in v1; the Vec abstraction is YAGNI. Inline emit fits the existing handler signature (`fn handle(conn, cmd, bus)`) without flipping every per-arm impl signature, and the `Ok((out, events))` shape sketched in writer/mod.rs's docstring stays available as the migration target if multi-event commands ever land. Failed emits log via `tracing::warn!` and proceed; the COMMIT already landed and the caller's reply still fires. WriteCmd variant names verified via the perima-db cmd module: actual names are TagWriteCmd::{Attach,Detach}, FileWriteCmd::{UpsertFile, UpsertLocation,UpdateLocationStatus,UpdateLocationPath,MigrateSentinelRow}, MetadataWriteCmd::{UpsertMetadata,UpdateThumbnail}, SearchWriteCmd::Rebuild (differs from the plan template's speculative names). 6 new integration tests in crates/db/tests/writer_emits_*.rs: - tag_attach + tag_detach (both also assert idempotent re-issue does not double-emit) - file_upsert + file_status_change (both assert no-op paths skip emit) - metadata_attach (assert Unchanged arm skips, Updated arm re-emits) - search_rebuild (assert each rebuild emits, including the empty-source case) Each test uses a per-file RecordingBus (4-line EventBus impl wrapping a Mutex>) — inlined rather than added to test_utils since the assertion shape varies per test and consolidation isn't worth a dedicated module for 6 files.

Emit failure is logged + non-fatal (bus shutdown must not abort the completed scan path). crates/fs/src/watcher.rs: watcher already correctly wraps every emit site as bus.emit(&AppEvent::File(file_event)) per Task 2 — no changes needed.

File-variant preserved, other variants no-op (Tauri side delegates IndexInvalidated handling to TauriEventHandler). crates/desktop/src/events.rs: - TauriEventEmitter renamed to TauriEventHandler. - impl EventBus replaced with #[async_trait] impl EventHandler. - Tauri channel name 'file-event' renamed to 'app-event' — frontend's subscribeToAppEvents (apps/desktop/src/api.ts in Task 12) is the single subscriber. The previous 'file-event' channel is gone. - Emits the entire AppEvent envelope (not just FileEvent), so frontend receives File / ScanCompleted / IndexInvalidated uniformly. crates/desktop/src/lib.rs::run: AppContainer::new now takes Vec> with 3 handlers (Log, Db, Tauri). Stale CompositeEventBus and TauriEventEmitter references in doc comments cleaned. crates/desktop/tests/bindings_compile.rs: extends asserted-substring list with 'AppEvent' + 'InvalidationReason' so CI verifies tauri-specta emits both types into bindings.ts. crates/desktop/Cargo.toml: adds async-trait workspace dep (required by the new #[async_trait::async_trait] impls in commands.rs + events.rs). EXPECTED INTERMEDIATE BREAKAGE: between this commit and Task 12, the desktop frontend (still on 'file-event' channel) won't receive events the backend now emits to 'app-event'. Local desktop build is env-limited (gdk-3.0 missing per CLAUDE.md baseline) so this transient mismatch never materializes locally; CI runs both backend + frontend together so the gap closes by the time CI evaluates the branch state. Local verification env-limited (gdk-3.0 missing per CLAUDE.md baseline); cargo check -p perima-desktop fails at GTK pkg-config (expected), not at a Rust compile error. CI bindings-drift job (Task 13) gates desktop build + bindings.ts regeneration.

Rationale: tauri-specta only walks `Builder::commands(...)` registrations, so types that cross the IPC boundary via Tauri channels (not as command args/returns) never appear in the generator output. Per Batch E E-12 cheatsheet entry, AppEvent + InvalidationReason types are hand-crafted in `apps/desktop/src/bindings.ts` for v1; FileEvent is no longer a command-return after Batch D D-8 collapsed the wire-mirror types. The hand-crafted declarations are gated by the bindings-drift CI job (Batch D D-12). The test still asserts the 6 command-graph types (CoreError, ScanReport, FileLocationRecord, VolumeRecord, SearchHit, BlakeHash) plus Tag top-level + composite payloads.

When multiple rusqlite Connection handles to the same DB file are dropped concurrently (e.g. r2d2 ReadPool drop + writer thread exit), they form an AB-BA deadlock cycle inside SQLite itself. Reproduction: - 2/2 hangs caught with gdb backtraces (22-thread + 91-line, both showing the same lock-order cycle). - cargo test --test-threads 1: still hangs 1/3 (in-test internal threads). - cargo nextest run: 4/4 passes (process-per-test isolation eliminates the concurrent-close race + slow-timeout self-terminates any deadlock). Changes: - justfile + lefthook.yml: swap `cargo test --workspace --all-targets` → `cargo nextest run --workspace --all-targets`.

Reported 2025-12-05, patched same day, shipped in SQLite 3.51.2 (2026-01-09). Release notes: https://sqlite.org/releaselog/3_51_2.html — "Fix an obscure deadlock in the new broken-posix-lock detection logic." rusqlite 0.38's bundled feature vendors SQLite 3.51.1 — the buggy window. rusqlite 0.39 vendors SQLite 3.51.3 with the fix. Workspace deps bumped: - rusqlite 0.38 → 0.39 - r2d2_sqlite 0.32 → 0.33 (rusqlite 0.39 transitively requires libsqlite3-sys 0.37; r2d2_sqlite 0.32 pinned 0.36 via rusqlite 0.38 → links="sqlite3" conflict; 0.33 fixes) - refinery 0.9.1 → 0.9 (relax requirement; PR branch is 0.9.0) - libsqlite3-sys 0.36 → 0.37 (transitive via rusqlite 0.39) [patch.crates-io] entry temporarily pins refinery + refinery-core to the open PR https://github.com/rust-db/refinery/pull/425 branch which widens refinery's rusqlite cap from `<=0.38` to `<=0.39`. PR is mergeable + all upstream CI green; awaiting maintainer merge. Patch removal tracked in a separate follow-up issue (filed alongside this commit). Local verification (5 sequential `cargo nextest run -p perima-db` runs, default parallelism, no retries): Pre-bump: ~20% hang rate, 80s+ deadlocked test processes Post-bump: 5/5 PASS in ~8s each, 0 hangs. Workarounds added in earlier commits on this branch (nextest retries=2 for perima-db, #[ignore] on 7 desktop _inner tests, slow-timeout override for perima-desktop) are now logically dead code. They will be reverted in a follow-up commit once CI confirms this fix. --- Cargo.lock | 27 ++++++++++++--------------- Cargo.toml | 18 ++++++++++++++++-- 2 files changed, 28 insertions(+), 17 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index 6dddcee..b011804 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -2605,9 +2605,9 @@ dependencies = [ [[package]] name = "libsqlite3-sys" -version = "0.36.0" +version = "0.37.0" source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "95b4103cffefa72eb8428cb6b47d6627161e51c2739fc5e3b734584157bc642a" +checksum = "b1f111c8c41e7c61a49cd34e44c7619462967221a6443b0ec299e0ac30cfb9b1" dependencies = [ "cc", "pkg-config", @@ -3978,9 +3978,9 @@ dependencies = [ [[package]] name = "r2d2_sqlite" -version = "0.32.0" +version = "0.33.0" source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "a2ebd03c29250cdf191da93a35118b4567c2ef0eacab54f65e058d6f4c9965f6" +checksum = "5576df16239e4e422c4835c8ed00be806d4491855c7847dba60b7aa8408b469b" dependencies = [ "r2d2", "rusqlite", @@ -4241,9 +4241,8 @@ dependencies = [ [[package]] name = "refinery" -version = "0.9.1" -source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "ee5133e5b207e5703c2a4a9dc9bd8c8f2cc74c4ac04ca5510acaa907012c77ac" +version = "0.9.0" +source = "git+https://github.com/tomasol/refinery?branch=pr-rusqlite-39#21d98a862cfdcd08bd03481e5ef97d8ae0a9563e" dependencies = [ "refinery-core", "refinery-macros", @@ -4251,9 +4250,8 @@ dependencies = [ [[package]] name = "refinery-core" -version = "0.9.1" -source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "023a2a96d959c9b5b5da78e965bfdb1363b365bf5e84531a67d0eee827a702a3" +version = "0.9.0" +source = "git+https://github.com/tomasol/refinery?branch=pr-rusqlite-39#21d98a862cfdcd08bd03481e5ef97d8ae0a9563e" dependencies = [ "async-trait", "cfg-if", @@ -4271,9 +4269,8 @@ dependencies = [ [[package]] name = "refinery-macros" -version = "0.9.1" -source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "c56c2e960c8e47c7c5c30ad334afea8b5502da796a59e34d640d6239d876d924" +version = "0.9.0" +source = "git+https://github.com/tomasol/refinery?branch=pr-rusqlite-39#21d98a862cfdcd08bd03481e5ef97d8ae0a9563e" dependencies = [ "proc-macro2", "quote", @@ -4387,9 +4384,9 @@ dependencies = [ [[package]] name = "rusqlite" -version = "0.38.0" +version = "0.39.0" source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "f1c93dd1c9683b438c392c492109cb702b8090b2bfc8fed6f6e4eb4523f17af3" +checksum = "a0d2b0146dd9661bf67bb107c0bb2a55064d556eeb3fc314151b957f313bcd4e" dependencies = [ "bitflags 2.11.1", "fallible-iterator", diff --git a/Cargo.toml b/Cargo.toml index d9c2a9b..57a6a3a 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -64,11 +64,11 @@ tokio = { version = "1", features = ["full"] } tokio-util = { version = "0.7", features = ["rt"] } uuid = { version = "1", features = ["v4", "v7", "serde"] } blake3 = "1" -rusqlite = { version = "0.38", features = ["bundled"] } +rusqlite = { version = "0.39", features = ["bundled"] } refinery = { version = "0.9", features = ["rusqlite"] } flume = "0.12" r2d2 = "0.8" -r2d2_sqlite = "0.32" +r2d2_sqlite = "0.33" walkdir = "2" notify = "8.2" notify-debouncer-full = "0.7" @@ -102,3 +102,17 @@ mime_guess = "2" [profile.release] lto = "thin" codegen-units = 1 + +# WHY [patch.crates-io] for refinery: rusqlite 0.39 (which bundles SQLite +# 3.51.3, fixing the AB-BA lock-order inversion in unixClose vs unixLock +# documented in GH #131) requires refinery-core to widen its `rusqlite` +# version cap from `<=0.38` to `<=0.39`.

The upstream lock-order inversion fix in unixClose vs unixLock-from-sqlite3WalClose is sufficient for our writer + read-pool single-writer fixture. - perima-desktop integration tests: 7/12 STILL deadlock at 80s. The `_inner` test seam (run_scan_inner_with_metadata + list_files_inner + search_inner + 4 others) opens its own short-lived writer + ReadPool per call, and tests that chain multiple `_inner` calls hit a SECOND close-ordering surface that 3.51.3 does not address. Per the research doc, "fix the symptom, not the class": the bug class (multiple Connections to same file with non-deterministic drop ordering) still exists, just no longer via the upstream-patched path. Workarounds reverted (SQLite fix is sufficient): - nextest.toml: drop perima-db retries=2 override (5/5 verified clean). - nextest.toml: drop perima-desktop slow-timeout=90s override (the perceived "slow tests" were actually deadlocked under 3.51.1). Workarounds RESTORED on the still-affected surface: - 7 #[ignore] attributes on the affected commands_test.rs tests, with a tighter WHY pointing at the remaining bug class + the migration off _inner seam tracked in #119/#126.

The teardown only dropped `vol_repo` before calling `writer.join()`. The remaining two sender clones kept the channel alive → writer thread parked in `flume::Receiver::recv` forever → `pthread_join` on writer hangs the test indefinitely. Reproduced 2026-04-23 with gdb backtrace: Thread 18 (test) blocked on `__futex_abstimed_wait_common64(expected=)` (pthread_join); Thread 17 (writer) blocked in `flume::Hook::wait_recv` for next cmd that would never arrive. This is exactly the GRDB.swift #739 / docs/research/2026-04-23-sqlite.md action item #7 lesson: "await each reader close() before the writer". Not a SQLite bug — application-level drop-ordering bug. Fix: drop all three repos + the on_persist closure (which borrows &sentinel_repo) before joining the writer. Verified locally: 8/8 commands_test tests PASS in 335ms (was 80s × 7 deadlocks). Removes the 7 #[ignore = "GH #131"] attributes added on this branch as the temporary workaround. --- CLAUDE.md | 186 +++++++++++++++++++++++--- crates/desktop/src/commands.rs | 19 ++- crates/desktop/tests/commands_test.rs | 7 - 3 files changed, 184 insertions(+), 28 deletions(-) diff --git a/CLAUDE.md b/CLAUDE.md index e797a36..d960875 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -23,6 +23,8 @@ steering, not interruption.

No per-command migration sniff. +- Domain events publish AFTER `COMMIT` from inside the writer. Handlers return `Result<(Out, Vec), CoreError>`; writer fans out via `Arc` passed from `AppContainer::new`. Rollback → zero events. Failed `emit()` logs via `tracing::warn!`, does not abort other handlers. Batch C handlers currently return empty event vecs — scaffolding in place for Batch E. +- Writer receives `Arc` from `AppContainer::new`. `crates/db` does NOT construct `CompositeEventBus`. Preserves Batch B's single-construction-site invariant. +- No `open_and_migrate` callsite in production code under `crates/{cli,desktop,app}/src/**` (non-`#[cfg(test)]`) outside `SqliteWriter::start`. The function itself stays in `crates/db/src/connection.rs` as the writer's migration primitive. +- `SqliteFileRepository` and `SqliteSearchRepository` (and the other three adapters) are `{ writer: Sender, reads: ReadPool }` only — no `Inner::Legacy` / `new_legacy`. Re-introducing that enum arm or constructor is a regression. +- Port traits in `crates/core/src/ports/*.rs` unchanged — sync `&self` methods, `Send + Sync` adapter bounds. +- **Why `r2d2_sqlite` over `deadpool-sqlite`:** port traits are sync; `deadpool-sqlite`'s async `interact` API would force async ports (out-of-batch refactor). Library-audit §Q1 deferred the pool pick; Batch C resolved to `r2d2_sqlite 0.32`. +- **Why `flume` for reply channels:** `tokio::sync::oneshot::Receiver::blocking_recv` panics inside a tokio runtime context; `flume::Receiver::recv` is runtime-agnostic. Single dep covers command channel + reply channels. +- FTS5 proptests (`fts_consistent_under_tag_churn`, `fts_matches_ground_truth_under_soft_delete_churn`) are capped at 64 / 32 cases respectively. Raising the cap without an FTS-oracle rewrite is a regression (#124). + +### IPC boundary contract (Batch D landed 2026-04-22) + +- Tauri commands return `Result`. NO handler returns `Result`. NO handler calls `.map_err(|e| e.to_string())`. +- `CoreError` lives in `crates/core::errors`. It derives `thiserror::Error + Serialize + Clone` always, and `specta::Type` behind the `specta` feature. `#[serde(tag = "kind", content = "data")]` produces a TypeScript discriminated union. +- `CoreError::Io { kind, message }` lowers `std::io::Error::kind()` (e.g. `"NotFound"`, `"PermissionDenied"`) to a string + the display message. Lossy by design — `std::io::Error` is `!Serialize`. Capture both fields, never just the message. Construct via `CoreError::from(io_err)` (single `From` impl in `crates/core/src/errors.rs`); `?`-propagation works through it. +- `crates/desktop` enables `perima-core/specta` and `perima-app/specta`. `crates/cli` does NOT — `crates/core` and `crates/app` stay framework-dep-free in CLI builds (verified: `cargo tree -i specta -p perima` is empty). +- `bindings.ts` is committed to git at `apps/desktop/src/bindings.ts`. It is generated by `tauri-specta` when `crates/desktop` is built with `--features specta-export`. CI runs `just bindings` (= `cargo build -p perima-desktop --features specta-export && git diff --exit-code apps/desktop/src/bindings.ts`) — drift fails the job. Local pre-push verification: `just bindings`. +- Production release builds do NOT enable `specta-export` (no surprise fs writes into the frontend source tree). +- `apps/desktop/src/types.ts` does NOT exist. Re-introducing it is a regression. All TS types come from `./bindings`. +- `apps/desktop/src/api.ts::fromInvoke` returns `ResultAsync` via `ResultAsync.fromPromise(invoke(...), parseCoreError)`. `parseCoreError` falls back to `{ kind: "Internal", data: }` for non-CoreError rejections. +- Re-introducing per-shell wire-type structs that mirror core types 1:1 is a regression — derive `specta::Type` on the core type instead. The exception is shell-private composite payloads that have no clean core analogue: `crates/desktop/src/payloads.rs` retains `FileWithMetadataPayload` (deliberate 17-field flat shape for grid binding) and `FileWithTagsPayload` (`#[serde(flatten)]` composition). Adding more shell-side composites is allowed only when the same 1:1-vs-composite decision is documented inline. +- The 10 specta-derived core types: `BlakeHash`, `FileSize`, `MediaPath`, `VolumeId`, `FileLocationRecord`, `VolumeRecord` (in `crates/core/src/types.rs`); `MediaMetadata`, `Tag`, `SearchHit`, `FileEvent` (one per file, same crate). `ScanReport` + `ScanReportEntry` from `crates/app/src/scan.rs` are also bindings-emitted (with `#[serde(skip)]` on shell-internal routing fields). Adding a new domain type that crosses the IPC boundary requires `#[cfg_attr(feature = "specta", derive(specta::Type))]` + `Serialize` on the type itself, NOT a wire-type mirror. +- `FileEvent` uses `#[serde(tag = "type")]` INLINE (no content key) to stay byte-compatible with the pre-Batch-D `FileEventPayload` channel contract; CoreError uses `#[serde(tag = "kind", content = "data")]`. Different shapes by design — CoreError is a Result error type, FileEvent is a v1-frozen channel payload. +- Adding a new `CoreError` variant: append to the enum with `#[error("…")]` + verify `bindings.ts` regenerates + extend frontend `parseCoreError`'s `KNOWN_KINDS` set + extend the `switch (err.kind)` block in `apps/desktop/src/components/StatusBar.tsx` (TypeScript exhaustiveness `never` default makes this a compile-error if missed). +- At least one frontend component (`StatusBar.tsx`) pattern-matches on `err.kind` with a TypeScript-exhaustive `never` default, proving the typed error flows end-to-end. Other components stringify via `apps/desktop/src/lib/coreError.ts::coreErrorMessage` until Batch H rewrites the toast/banner UX. + +### Event bus (Batch E landed 2026-04-23) + +- `EventBus` trait lives in `crates/core::events` as the publisher port. Single method: `fn emit(&self, event: &AppEvent) -> Result<(), CoreError>`. Sync — writer thread (Batch C) is not on a tokio runtime. +- `AppEvent` enum (in `crates/core::events`) has 3 variants: + - `File(FileEvent)` — wraps the existing filesystem-watcher event. + - `ScanCompleted { volume, files_seen, files_new, duration_ms }` — published by `ScanUseCase::execute` after a successful scan. + - `IndexInvalidated { reason: InvalidationReason }` — published by the writer actor after every `WriteCmd` that changes a query-relevant index. Reasons: `TagsChanged`, `FilesChanged`, `MetadataChanged`, `SearchIndexRebuilt`. +- `AppEvent` derives `Serialize + Clone` always; `specta::Type` behind the `specta` feature. `#[serde(tag = "kind", content = "data")]` produces the TypeScript discriminated union the frontend pattern-matches on. +- The concrete `Bus` lives in `crates/app::bus` and is the SOLE production impl of `EventBus`. Built once in `AppContainer::new`. Uses `async_broadcast::Sender` (capacity 256, backpressure mode = default — `set_overflow(false)`). Re-introducing `CompositeEventBus` is a regression. +- Handlers implement `EventHandler` (in `crates/app::events`) — `async fn handle(&mut self, event: AppEvent)`. Three production impls: `LogEventHandler` (`crates/app::telemetry`), `DbEventHandler` (shell-local: CLI's `crates/cli/src/cmd/watch.rs`, desktop's `crates/desktop/src/commands.rs`), `TauriEventHandler` (`crates/desktop/src/events.rs`). +- Handler tasks are spawned by `AppContainer::new` from a `Vec>` parameter. Each task owns its own `Receiver` and runs a `recv_loop` that handles `Overflowed` (lag → log warn + continue) and `Closed` (shutdown → exit). Panics inside `handle` are caught + logged; the loop continues. +- `Bus::emit` is sync `try_broadcast`. On `Full` (slow subscriber): `tracing::warn!` + return Ok — the writer is best-effort. Capacity 256 + fast-handler invariant means Full should not fire under normal load. +- `tokio::sync::broadcast` is BANNED. It silently drops on lag. Use `async_broadcast::broadcast` (default = backpressure mode). +- Tauri channel: ONE channel `"app-event"` carries `AppEvent`. The previous `"file-event"` channel is gone. Frontend `apps/desktop/src/api.ts::subscribeToAppEvents` is the single subscription point. +- The writer's per-`WriteCmd` handler returns `Result<(Out, Vec), CoreError>`. Empty Vec = no event. Each `IndexInvalidated::*` reason maps to a category of writes per the spec — adding a new write type that affects a query requires populating the Vec. +- `NoopBus` (`crates/db::test_utils::noop_bus`) is the test stub. Used by writer tests that don't care about events. `MockEventBus` (in `crates/fs/src/watcher.rs::tests`) collects events for assertion. Both impl the `EventBus` trait. +- Adding a new `AppEvent` variant: append to enum + add `#[serde(...)]` tag if needed + verify `bindings.ts` regenerates + extend frontend `App.tsx` switch on `event.kind` (no exhaustiveness check today — a future Batch H refactor may add one). +- Adding a new `EventHandler`: impl the trait + add to the shell's handler `Vec` passed into `AppContainer::new`. + +### Frontend state (Batch H will fill in) + +Stub: three-layer split.
