docs(v1.1.3-modules): handback report
§8 verified on the immediately-prior commit (3dbead4):
- cargo fmt --all -- --check: exit 0
- cargo clippy --all-targets --all-features -- -D warnings: exit 0
- cargo test --workspace: exit 0, 358 passed / 0 failed / 140 ignored
- (cd dashboard && npm run check): exit 0, 0 errors / 0 warnings
This commit only touches HANDBACK.md, so the §8 attestation continues
to apply to the working tree.

**Iteration 2 note**: the original v1 HANDBACK §8 claimed `cargo fmt --check` was green; that claim was false against HEAD at audit time (one single-line collapse diff in `docs_service.rs::delete`'s `$in` arm). Iteration 2 adds the chore commit fixing that and this HANDBACK update replacing §8's attestation with one I actually verified post-fix. The discipline lesson is recorded for the v1.1.3 retro: never claim a gate is green without re-running it on the exact HEAD I'm handing back.

| Scope item (from brief) | Status | Notes |
|
| # | Brief item | Status | Notes |
|
||||||
|
|---|---|---|---|
|
||||||
|
| 1 | `scripts.kind` column + check + index | **Done** | `migrations/0015_scripts_kind.sql` |
|
||||||
|
| 2 | Module syntax constraints (fn / const / import only) | **Done** | Walks `ast.statements()` via `rhai/internals`. Admin endpoint is primary gate; resolver re-runs the check for defense-in-depth. |
|
||||||
|
| 3 | `ModuleResolver` replaces `DummyModuleResolver` | **Done** | `crates/executor-core/src/module_resolver.rs`; per-call instance with cross-app isolation, cycle detect, depth limit. |
|
||||||
|
| 4 | Two AST caches (script + module) | **Done** | Script cache in `LocalExecutorClient`; module cache in `Engine`. Both invalidate by `updated_at` comparison. Env-overridable sizes. |
|
||||||
|
| 5 | Dep-graph table + populate | **Done** | `migrations/0016_script_imports.sql`; `replace_imports_tx` writes edges in the same transaction as the script INSERT/UPDATE. |
|
||||||
|
| 6 | Admin endpoint changes (kind, kind-change rejection, route/trigger module rejection) | **Done** | Also closes a latent cross-app trigger gap (script.app_id mismatch — see §7). |
|
||||||
|
| 7 | Dashboard surface (kind dropdown + badge) | **Done** | App page form + scripts list + script detail header. `npm run check` clean. |
|
||||||
|
| 8 | `ModuleSource` trait shape | **Done** | Lives in `picloud-shared`; matches the v1.1.1/v1.1.2 service pattern. |
|
||||||
|
| 9 | Version bumps | **Done** | Workspace 1.1.2→1.1.3, SDK 1.3→1.4, dashboard 0.8.0→0.9.0. |
|
||||||
|
| 10 | Tests (~40–60) | **Done** | 46 new tests across 5 crates. Gates green. |
|
||||||
|
|
||||||
|
### Scope-out items (confirmed NOT built)
|
||||||
|
|
||||||
|
- No module versioning / pinning, no `@v3` syntax.
|
||||||
|
- No eager precompilation at save-time.
|
||||||
|
- No dashboard dep-graph visualization.
|
||||||
|
- No LISTEN/NOTIFY-based cross-node invalidation.
|
||||||
|
- No new `Scope` variants (modules use existing `script:read` / `script:write`).
|
||||||
|
- No admin GET endpoints for `script_imports` (the table is persisted for v1.2+; no v1.1.3 read surface — see §10 deferred items).

## 3. Resolver implementation notes
|
||||||
|
|
||||||
|
### 3.1 In-progress-imports stack
|
||||||
|
|
||||||
|
Lives **on the per-call `PicloudModuleResolver` instance**, not on `SdkCallCx`. The resolver is constructed fresh per `Engine::execute_ast` call (see `crates/executor-core/src/engine.rs:execute_ast`), so the stack is naturally scoped to one execution. Both the stack and the depth counter are `Mutex<…>` (not `RefCell<…>`) because `rhai::ModuleResolver: SendSync` under the `sync` feature.
|
||||||
|
|
||||||
|
An RAII `StackGuard` pops the stack and decrements depth on drop — a compile error or panic anywhere inside `resolve()` cleans up properly. The lock is uncontended in practice (Rhai evaluation on the engine is single-threaded).
|
||||||
|
|
||||||
|
### 3.2 Sync → async bridge
|
||||||
|
|
||||||
|
Rhai's `ModuleResolver::resolve` is sync; `ModuleSource::lookup` is async. The bridge:
|
||||||
|
|
||||||
|
```rust
|
||||||
|
let handle = tokio::runtime::Handle::try_current().map_err(/* surfaces as ErrorRuntime */)?;
|
||||||
|
let lookup = tokio::task::block_in_place(|| handle.block_on(self.source.lookup(&self.cx, path)));
|
||||||
|
```
|
||||||
|
|
||||||
|
- `try_current()` (not `current()`) so test harnesses that build an `Engine` outside a Tokio runtime get a clean error instead of a panic.
|
||||||
|
- `block_in_place` makes the call safe both on `spawn_blocking` threads (where it's a no-op) and on multi-threaded runtime worker tasks (where it instructs the runtime to relocate other tasks before we block). This was load-bearing for the resolver tests, which call `engine.execute` directly from `#[tokio::test(flavor = "multi_thread")]`.
|
||||||
|
- A `current_thread` runtime still panics — but production callers wrap `Engine::execute` in `tokio::task::spawn_blocking` (see `LocalExecutorClient::execute_with_identity`), which avoids that path entirely.
|
||||||
|
|
||||||
|
### 3.3 Cross-app isolation enforcement
|
||||||
|
|
||||||
|
The resolver captures `Arc<SdkCallCx>` at construction. Every `ModuleSource::lookup` call passes `&self.cx`. The Postgres impl (`crates/manager-core/src/module_source.rs`) selects with `WHERE app_id = $1 AND kind = 'module' AND name = $2`, binding `$1` from `cx.app_id.into_inner()` — never from any script-passed argument. The Rhai script's `import "name" as alias;` syntax has no slot for an `app_id`, so there is no path by which a script in app A can name a row in app B.
|
||||||
|
|
||||||
|
Verified by `resolver_cross_app_blocked` and `resolver_cross_app_module_not_found` tests.
|
||||||
|
|
||||||
|
### 3.4 Module-shape validation — both layers
|
||||||
|
|
||||||
|
- **Primary gate (admin endpoint)** — `manager-core::api::create_script` and `update_script` call `state.validator.validate_module(src)` whenever the effective kind is `Module`. `Engine`'s impl walks `ast.statements()`, accepting only `Stmt::Var(_, ASTFlags::CONSTANT, _)`, `Stmt::Import(..)`, and `Stmt::Noop(..)`. Anything else (top-level expression, let, if, while, …) is rejected with a clear `ValidationError::ModuleShape` message.
|
||||||
|
- **Defense in depth (resolver)** — the resolver calls `check_module_shape` again after `engine.compile(source)`. This catches rows that bypassed the API (manual SQL inserts, future migration bugs, restoring from an older backup).
|
||||||
|
|
||||||
|
Note: Rhai's default optimizer constant-folds `if true { ... }` away, so a module containing `if true { ... }` parses to an empty body and passes vacuously. This is fine semantically (the script has no observable behavior), but it surprises authors. Documented as a known acceptance edge; not worth disabling optimization for.
|
||||||
|
|
||||||
|
### 3.5 What the resolver does NOT enforce
|
||||||
|
|
||||||
|
- **Module access permissions** — every module in an app is importable by every other script in the same app. Per-module ACLs are explicitly v1.2+.
|
||||||
|
- **Module versioning / pinning** — there's exactly one current version per `(app_id, name)`. v1.3+.
|
||||||
|

## 4. Cache design notes
|
||||||
|
|
||||||
|
### 4.1 LRU library
|
||||||
|
|
||||||
|
**`lru = "0.12"`** — added to `[workspace.dependencies]`. Standard choice, no-frills crate (`LruCache<K, V>` with `put`/`get`/`len`/etc.). Both caches use `Arc<Mutex<LruCache<K, V>>>` so they're cheap to clone and safe to share across executions.
|
||||||
|
|
||||||
|
### 4.2 Cache key shapes + what's stored
|
||||||
|
|
||||||
|
| Cache | Owner | Key | Value | Stores |
|
||||||
|
|---|---|---|---|---|
|
||||||
|
| **Script AST cache** | `LocalExecutorClient` | `ScriptId` | `CachedScript { updated_at: DateTime<Utc>, ast: Arc<rhai::AST> }` | Compiled AST for the top-level (endpoint) script. |
|
||||||
|
| **Module cache** | `Engine` | `(AppId, String)` | `CachedModule { updated_at: DateTime<Utc>, module: Shared<rhai::Module> }` | Compiled `rhai::Module` produced by `Module::eval_ast_as_new`. |
|
||||||
|
|
||||||
|
The script cache stores `Arc<AST>` so an evaluation can grab a cheap clone and hand it to `Engine::execute_ast` without holding the cache lock. The module cache stores `Shared<Module>` (= `Arc<Module>` under the `sync` feature) because that's what `ModuleResolver::resolve` must return.
|
||||||
|
|
||||||
|
### 4.3 Stale-version detection
|
||||||
|
|
||||||
|
Both caches use the same logic: **compare `cached.updated_at` against the freshly-known `updated_at`**.
|
||||||
|
|
||||||
|
- For the script cache, the caller passes the fresh value as `ScriptIdentity.updated_at` — the orchestrator already loaded the script row to dispatch the request, so there's no extra DB hit.
|
||||||
|
- For the module cache, the resolver must call `ModuleSource::lookup` first to learn the fresh `updated_at` — every `import` does at least one DB roundtrip. That's a deliberate trade-off (documented in CHANGELOG): the alternative (TTL caching or pub/sub) introduces staleness during edits and complicates "publish a fix immediately" UX. Worth re-evaluating in v1.3+ when LISTEN/NOTIFY makes pub/sub cheap.
|
||||||
|
|
||||||
|
Mismatch → recompile + `cache.put(...)` replace. LRU eviction is automatic when capacity is exceeded.
|
||||||
|
|
||||||
|
### 4.4 Capacity overrides
|
||||||
|
|
||||||
|
- `PICLOUD_SCRIPT_CACHE_SIZE` (default 256, `LocalExecutorClient`)
|
||||||
|
- `PICLOUD_MODULE_CACHE_SIZE` (default 512, `Engine`)
|
||||||
|
|
||||||
|
Both clamp `max(1)` to avoid the LRU constructor's panic on zero. `Engine::with_module_cache_capacity` and `LocalExecutorClient::with_script_cache_capacity` give tests explicit handles.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 5. Dep-graph population
|
||||||
|
|
||||||
|
### 5.1 Where the extraction happens
|
||||||
|
|
||||||
|
Inside the `ScriptValidator` impl on `Engine`. The trait now returns `ValidatedScript { imports: Vec<String> }`, populated by `extract_imports` (endpoint scripts) or `validate_module_source` (module scripts). Both walk `ast.statements()` and pull out `Stmt::Import(boxed_path_expr, _)` where the path is a `StringConstant`.
|
||||||
|
|
||||||
|
**Dynamic imports** (`import some_var as alias;`) are NOT captured because we can't know the name at compile time. Tested by `validate_endpoint_skips_dynamic_imports_in_imports_list`. Documented as a known limitation in the CHANGELOG and migration 0016's header comment.
|
||||||
|
|
||||||
|
### 5.2 Where the write happens — transactional with the script INSERT/UPDATE
|
||||||
|
|
||||||
|
`PostgresScriptRepository::create` and `update` both open a `tx = pool.begin().await?`. The script row is inserted/updated inside the tx; immediately after, `replace_imports_tx(&mut tx, importer, app_id, &imports)` runs. The tx is committed at the end. If any step fails, both the script change and the dep-graph mutation roll back together. No half-state where the script row exists but the edges don't (or vice versa).
|
||||||
|
|
||||||
|
`replace_imports_tx`:
|
||||||
|
|
||||||
|
1. `DELETE FROM script_imports WHERE importer_script_id = $1` — replaces wholesale.
|
||||||
|
2. `INSERT INTO script_imports ... SELECT ... FROM scripts WHERE app_id = $1 AND kind = 'module' AND name = ANY($3) ON CONFLICT DO NOTHING` — best-effort: only resolves to existing modules in the same app; unresolved names are silently skipped (no error). A later save of either script re-resolves and writes the edge.
|
||||||
|
|
||||||
|
### 5.3 Schema decisions
|
||||||
|
|
||||||
|
- `script_imports.app_id` is denormalized but useful: the "all imports in app X" scan happens once at boot for caching and (eventually) for the dashboard's audit view. Without it, that query would need a 3-way join.
|
||||||
|
- `created_at` is unused by v1.1.3 logic but trivial to add now and useful for v1.2+ "first imported" diagnostics.
|
||||||
|
- The FK on `imported_script_id` cascades — when a module is deleted, every edge referencing it goes too. The cascade isn't exercised by a unit test (it would need Postgres); it's covered by the FK design.

||||||

## 6. Tests added
|
||||||
|
|
||||||
|
46 new tests across 5 crates. All green on HEAD `3dbead4`. Inventory:
|
||||||
|
|
||||||
|
### `crates/executor-core/tests/modules.rs` (NEW — 23 tests)
|
||||||
|
|
||||||
|
End-to-end through `Engine::execute` with a `CountingModuleSource` (in-memory fake).

|
| # | Test | Covers |
|
||||||
|---|---|---|
|
|---|---|---|
|
||||||
| `docs` service trait + impl + Postgres repo | **Done** | `DocsService` in `picloud-shared`; `DocsServiceImpl` + `PostgresDocsRepo` in `manager-core`; wired into `Services`. |
|
| 1 | `resolver_loads_simple_module` | Happy path: `import "m" as m; m::add(2, 3)` → 5. |
|
||||||
| Rhai SDK surface (`docs::collection(name).{create,get,find,find_one,update,delete,list}`) | **Done** | `executor-core/src/sdk/docs.rs`. Handle pattern via `engine.register_type_with_name::<DocsHandle>` + `register_fn` per method. |
|
| 2 | `resolver_cross_app_blocked` | Modules with same name in two apps resolve to the calling app's version. |
|
||||||
| Query DSL v1.1.2 subset (`$eq`, `$ne`, `$gt`, `$gte`, `$lt`, `$lte`, `$in`, dot paths to 5 levels, `$sort`, `$limit`) | **Done** | `manager-core/src/docs_filter.rs` parser + AST; SQL emitted by `manager-core/src/docs_repo.rs::build_find_query`. Unsupported operators throw with v1.2 pointer. |
|
| 3 | `resolver_cross_app_module_not_found` | App B's `import "lonely"` returns ModuleNotFound when only app A has it. |
|
||||||
| `docs:*` trigger kind | **Done** | `TriggerKind::Docs`, `OutboxSourceKind::Docs`, `TriggerEvent::Docs { op, collection, id, data, prev_data }`, `docs_trigger_details` table, `POST /api/v1/admin/apps/{id}/triggers/docs` endpoint. |
|
| 4 | `resolver_module_not_found` | Missing module → `ErrorModuleNotFound`. |
|
||||||
| Dispatcher routes `OutboxSourceKind::Docs` | **Done** | Single-line match-arm extension at [dispatcher.rs:166](crates/manager-core/src/dispatcher.rs#L166): `Kv | DeadLetter | Docs` reuses generic `resolve_trigger` + `build_exec_request`. |
|
| 5 | `resolver_self_import_detected` | `a` imports `a` → circular error. |
|
||||||
| Authz: `Capability::AppDocsRead(AppId)` + `AppDocsWrite(AppId)` mapped to `script:read`/`script:write` | **Done** | No new `Scope` variants added — honors the seven-scope commitment. Read at Viewer, write at Editor (mirrors KV). |
|
| 6 | `resolver_circular_detected` | `a → b → a` → circular error. |
|
||||||
| Event emission (`ServiceEvent { source: "docs", op, collection, key: id, payload, old_payload }`) | **Done** | Best-effort emit after each successful mutation; `OutboxEventEmitter::emit_docs` fans out to matching triggers. |
|
| 7 | `resolver_depth_limit_enforced` | 9-deep chain with limit 8 → depth error. |
|
||||||
| `ctx.event.docs.prev_data` change-data-capture | **Done** | Repo's `update`/`delete` return the prior data via a CTE so the service can populate `old_payload`. `trigger_event_to_dynamic` in `engine.rs` builds the Rhai-visible map. |
|
| 8 | `resolver_depth_limit_just_under_succeeds` | 7-deep chain with limit 8 succeeds. |
|
||||||
| Migrations 0013 + 0014 | **Done** | 0013 = docs table + GIN-on-`jsonb_path_ops`. 0014 = CHECK extensions + `docs_trigger_details`. |
|
| 9 | `resolver_runtime_validation_rejects_top_level_expr` | DB-direct insert with top-level expr is caught by the resolver's re-validation. |
|
||||||
| Version bumps + CHANGELOG | **Done** | Workspace `1.1.1 → 1.1.2`, SDK `1.2 → 1.3`, dashboard `0.7.0 → 0.8.0`, CHANGELOG entry with downgrade caveats + known limitations. |
|
| 10 | `resolver_backend_error_surfaces` | `ModuleSourceError::Backend` propagates to a script-visible error. |
|
||||||
| Tests (~30–50 new) | **Done — 77 new tests** | 26 docs_filter + 10 docs_repo SQL-shape + 23 docs_service + 3 triggers_api (docs) + 15 bridge integration. |
|
| 11 | `module_cache_hit_reuses_compiled_module` | Second import of same module doesn't recompile. |
|
||||||
| Optional: prune `docs/v1.1.x-design-notes.md` §1–4 | **Skipped** | Left for a separate cleanup PR. §1–4 contain the rationale for v1.1.1 decisions that ship in code now; pruning is a doc-only change that doesn't touch v1.1.2's scope. |
|
| 12 | `module_cache_stale_invalidated_on_updated_at_change` | Editing the module surfaces immediately. |
|
||||||
|
| 13 | `module_cache_lru_evicts_when_capacity_exceeded` | Capacity 1 → only one entry survives. |
|
||||||
|
| 14 | `module_cache_keyed_by_app` | Same-named modules in different apps cache independently. |
|
||||||
|
| 15 | `endpoint_can_import_module` | An endpoint script consumes a module's fn end-to-end. |
|
||||||
|
| 16 | `module_can_import_module` | Modules can be importers. |
|
||||||
|
| 17 | `validate_module_accepts_fn_const_import_only` | fn / const / import body validates + extracts imports. |
|
||||||
|
| 18 | `validate_module_rejects_top_level_let` | `let x = 1;` rejected. |
|
||||||
|
| 19 | `validate_module_rejects_top_level_expr` | `42;` rejected. |
|
||||||
|
| 20 | `validate_module_rejects_top_level_while` | `while … { … }` rejected (chosen over `if true …` because Rhai folds constant-condition ifs). |
|
||||||
|
| 21 | `validate_endpoint_extracts_literal_imports` | Endpoint imports populate `ValidatedScript.imports`. |
|
||||||
|
| 22 | `validate_endpoint_top_level_expr_still_allowed` | Endpoints retain the looser rules. |
|
||||||
|
| 23 | `validate_endpoint_skips_dynamic_imports_in_imports_list` | Dynamic `import some_var as y` produces an empty list. |
|
||||||

## 3. Query DSL implementation notes

### `crates/orchestrator-core/src/client.rs` (6 inline tests)
|
||||||
|
|
||||||
### Operator dispatch path
|
| # | Test | Covers |
|
||||||
|
|---|---|---|
|
||||||
|
| 1 | `cache_hit_when_identity_matches` | Identical `(script_id, updated_at)` returns the same `Arc<AST>`. |
|
||||||
|
| 2 | `cache_invalidated_when_updated_at_changes` | Different `updated_at` recompiles. |
|
||||||
|
| 3 | `distinct_script_ids_cache_independently` | Two scripts → two entries. |
|
||||||
|
| 4 | `lru_eviction_caps_cache_size` | Capacity 1; A → B → C leaves one entry. |
|
||||||
|
| 5 | `script_identity_is_copy` | `ScriptIdentity: Copy` (load-bearing for many call sites). |
|
||||||
|
| 6 | `compile_error_does_not_poison_cache` | Failed compile doesn't insert; subsequent good compile succeeds. |
|
||||||
|
|
||||||
A script's filter is a Rhai `Map`. The bridge converts it to `serde_json::Value` via `dynamic_to_json` (no parsing here — the bridge stays thin) and hands it to `DocsService::find`. The service calls `docs_filter::parse_filter` which:
|
### `crates/shared/src/script.rs` (3 inline tests)
|
||||||
|
|
||||||
1. Validates the filter is a JSON object.
|
| # | Test | Covers |
|
||||||
2. Iterates each top-level entry:
|
|---|---|---|
|
||||||
- `$`-prefixed keys: `$sort` and `$limit` are accepted; anything else (`$or`, `$and`, etc.) returns `FilterParseError::UnsupportedOperator` with a script-visible message naming the operator + pointing at v1.2.
|
| 1 | `default_is_endpoint` | `ScriptKind::default() == Endpoint`. |
|
||||||
- Other keys: parsed as a `FieldPath` (validates non-empty, no `..`, no `$`-prefixed segments, depth ≤ 5). The value is either a scalar (implicit `$eq`) or an operator object — an object where **every** key starts with `$`. Mixed-shape objects reject as `InvalidFilter` since the user almost certainly meant operator dispatch.

| 2 | `round_trips_through_serde_lowercase` | `"endpoint"` / `"module"` wire form. |
|
||||||
3. Inside an operator object, each `$xxx` key dispatches through `ComparisonOp::from_dollar_key`. Unknown operators return `UnsupportedOperator`.
|
| 3 | `parse_str_round_trip` | `as_str` ↔ `parse_str` inverses. |
|
||||||
|
|
||||||
The resulting `DocsFilter { conditions, sort, limit }` is purely descriptive — no SQL or Postgres concepts leak in.

| # | Test | Covers |
|

|
|---|---|---|
|

|
| 1 | `kv_trigger_rejects_module_target` | Module script as KV-trigger target → 422 with `"module"` in the message. |
|

|
| 2 | `docs_trigger_rejects_module_target` | Same for docs triggers. |
|

|
| 6 | `kv_trigger_accepts_endpoint_target` | Happy path. |
|
||||||
|
|
||||||
`FieldPath::parse` splits on `.` and validates each segment. The `PostgresDocsRepo` SQL builder emits `jsonb_extract_path_text(data, $N1, $N2, …)` where each segment is bound as a separate text parameter. Postgres's `jsonb_extract_path_text` accepts a variadic text array, so depth doesn't change the SQL shape — only the bind count. This means depths 1 through 5 all flow through one helper (`push_jsonb_path`) without conditional branching on length.

## 7. Schema / decisions beyond the brief
|
||||||
|
|
||||||
|
- **Module name shape CHECK** (`migrations/0015_scripts_kind.sql`): module names are constrained to `^[a-zA-Z_][a-zA-Z0-9_]{0,63}$`. Endpoint scripts retain the looser pre-v1.1.3 name rules so existing rows aren't invalidated. Reason: Rhai imports modules by exact string; spaces / control characters make `import "<name>"` fragile.
|
||||||
|
- **Reserved module names**: rejected at create-time (`kv`, `docs`, `dead_letters`, `log`, `regex`, `random`, `time`, `json`, `base64`, `hex`, `url`, `http`, `files`, `pubsub`, `secrets`, `email`, `users`, `queue`). Not a security boundary — stdlib + module imports live in disjoint Rhai scopes — but a defense against author confusion.
|
||||||
|
- **`ScriptValidator` trait return shape changed** from `Result<(), ValidationError>` to `Result<ValidatedScript, ValidationError>`. Breaking trait change, but the only impl is `Engine` in executor-core — bounded blast radius.
|
||||||
|
- **`ExecutorClient` gains `execute_with_identity`** with a default impl that forwards to `execute`. This means `RemoteExecutorClient` keeps working without any cluster-mode awareness of the cache (the local impl handles it).
|
||||||
|
- **Latent security fix**: trigger creation now verifies `script.app_id == app_id`. v1.1.1 and v1.1.2's trigger endpoints didn't load the target script, so an app A member could (in principle) wire a trigger that targeted a script in app B. Closed in this release; called out in the CHANGELOG.

## 8. How to verify locally (verified on HEAD `3dbead4`)
|
||||||
|
|
||||||
|
After my last commit, I ran the three gates plus the dashboard check on the exact HEAD I'm handing back. **Actual** exit codes and counts (not pre-written):
|
||||||
|
|
||||||
|
### 8.1 `cargo fmt --all -- --check`
|
||||||
|
|
||||||
```
|
```
|
||||||
docs_filter::parse_filter
|
$ cargo fmt --all -- --check
|
||||||
└─ FilterParseError::{InvalidFilter, UnsupportedOperator}(String)
|
$ echo $?
|
||||||
└─ DocsServiceImpl::find via `From<FilterParseError> for DocsError`
|
0
|
||||||
└─ DocsError::{InvalidFilter, UnsupportedOperator}(String)
|
|
||||||
└─ executor-core::sdk::docs::block_on
|
|
||||||
└─ EvalAltResult::ErrorRuntime("docs: <message>")
|
|
||||||
```
|
```
|
||||||
|
|
||||||
The error string flows verbatim from the parser. The Rhai bridge prefixes `"docs: "` and surfaces it through `Box<EvalAltResult>`. Snapshot tests in `docs_filter::tests` pin three representative error strings (`$regex`, multi-field `$sort`, depth-limit) so changing them is a deliberate act.
|
Clean diff, **exit 0**.
|
||||||
|
|
||||||
### SQL builder — parameterised vs hardcoded
|
### 8.2 `cargo clippy --all-targets --all-features -- -D warnings`
|
||||||
|
|
||||||
This is the load-bearing security surface. The reviewer should audit `crates/manager-core/src/docs_repo.rs::build_find_query` and the `emit_condition` / `push_jsonb_path` helpers.
|
```
|
||||||
|
$ cargo clippy --all-targets --all-features -- -D warnings
|
||||||
**Hardcoded SQL fragments** (never come from user input):
|
Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.21s
|
||||||
- The base `SELECT id, data, created_at, updated_at FROM docs WHERE app_id = ` prefix.
|
$ echo $?
|
||||||
- The connector ` AND collection = `, ` AND ` between conditions, ` ORDER BY `, ` LIMIT `, `, id ASC` (sort tiebreaker).
|
0
|
||||||
- The comparison operator tokens: `=`, `IS DISTINCT FROM`, `IS NULL`, `IS NOT NULL`, `>`, `>=`, `<`, `<=`, `= ANY(`.
|
|
||||||
- The sort direction tokens: ` ASC`, ` DESC`.
|
|
||||||
- The `jsonb_extract_path_text(data` opening + closing `)`.
|
|
||||||
|
|
||||||
**Parameter-bound (every byte of user input)**:
|
|
||||||
- `app_id` (the cross-app isolation gate, always `$1`).
|
|
||||||
- `collection` (always `$2`).
|
|
||||||
- Every field-path segment (one `$N` per segment).
|
|
||||||
- Every comparison value (one `$N` per condition).
|
|
||||||
- The `$in` value list as a single `$N` bound as `TEXT[]`.
|
|
||||||
- The `$limit` integer as `$N` bound as `BIGINT`.
|
|
||||||
|
|
||||||
The SQL-shape guardrail test (`docs_repo::sql_shape_tests::every_query_starts_with_app_id_and_collection_predicate`) asserts every emitted query starts with the literal prefix `SELECT id, data, created_at, updated_at FROM docs WHERE app_id = $1 AND collection = $2`. The companion `no_user_string_literal_in_sql` and `no_user_path_literal_in_sql` tests pass a filter whose values contain SQL keywords (`"gold; DROP TABLE docs;--"`, `"drop_table_users"`) and assert those strings never appear in the emitted SQL.
|
|
||||||
|
|
||||||
### Semantic corner cases
|
|
||||||
|
|
||||||
- **`$ne` uses `IS DISTINCT FROM`** (not `<>`). `jsonb_extract_path_text` returns SQL NULL for missing paths + JSON nulls; `<>` would silently exclude those rows from `$ne` results. Tested in `docs_repo::sql_shape_tests::ne_with_value_uses_is_distinct_from`.
|
|
||||||
- **`$eq null`** emits `IS NULL`; **`$ne null`** emits `IS NOT NULL`. Avoids any `= NULL` / `<> NULL` shenanigans.
|
|
||||||
- **Comparison ops are text-lex** per the brief's contract (Decision E, confirmed). Known limitation surfaced in CHANGELOG + this HANDBACK: `'10' < '9'` is TRUE under any text collation, so unpadded numeric comparisons break across digit-count boundaries. Workaround for users: zero-pad numeric strings. v1.2's advanced-query expansion will add numeric-aware operators.
|
|
||||||
|
|
||||||
## 4. Schema decisions (beyond the brief)
|
|
||||||
|
|
||||||
The brief sketched the docs table; I refined it as follows:
|
|
||||||
|
|
||||||
- **GIN index uses `jsonb_path_ops`** (smaller index, supports `@>` containment for equality filter shapes). The default `jsonb_ops` would accelerate path-existence queries too — irrelevant for the v1.1.2 operator set.
|
|
||||||
- **Migration sequencing**: two migrations (0013_docs.sql + 0014_docs_triggers.sql) instead of one. Separates the data-plane addition from the triggers-framework extension cleanly; either could be reverted independently if needed.
|
|
||||||
- **CHECK constraint names**: relied on Postgres's auto-name convention for inline column-CHECKs (`<table>_<column>_check`). Migration 0014 drops `triggers_kind_check` + `outbox_source_kind_check` and re-adds the widened constraints. **The reviewer should confirm these auto-names match the inline definitions in 0008/0009** on a fresh Postgres before deploy.
|
|
||||||
- **`docs_trigger_details.ops` is `TEXT[] NOT NULL`** without a `DEFAULT '{}'` — matches `kv_trigger_details.ops`. Callers always supply a (possibly empty) array.
|
|
||||||
- **No `dispatch_mode` column on `docs_trigger_details`** — the parent `triggers.dispatch_mode` is sufficient. KV does the same.
|
|
||||||
|
|
||||||
## 5. Tests added (one line each)
|
|
||||||
|
|
||||||
### `crates/shared/src/docs.rs`

|
|
||||||
|
|
||||||
### `crates/manager-core/src/docs_repo.rs` (10 tests in `mod sql_shape_tests`)
|
|
||||||
- `every_query_starts_with_app_id_and_collection_predicate` — **load-bearing**: pins the cross-app isolation prefix across 8 representative filter shapes.
|
|
||||||
- `no_user_string_literal_in_sql` — value containing `"DROP TABLE"` never lands in SQL text.
|
|

|
||||||
- `empty_collection_rejected` — `""` collection.
|

||||||
- `create_with_non_object_data_rejected` / `update_with_non_object_data_rejected` — data must be a JSON object.
|
|
||||||

|
|
||||||
- `docs_trigger_empty_glob_rejected` — `" "` rejects with `Invalid`.
|

|
|
||||||
|
|
||||||
## 6. Open questions for the reviewer
|
|
||||||
|
|
||||||
1. **CHECK constraint name verification** — 0014 drops constraints named `triggers_kind_check` and `outbox_source_kind_check` (Postgres's default for inline column-CHECKs). Please verify by running migrations from scratch + a fresh `\d+ triggers` / `\d+ outbox` against a stage DB before merge. The CHANGELOG includes a downgrade caveat but the upgrade path itself depends on this name match.
|
|
||||||
2. **`docs_repo` Postgres-integration tests** — I wrote SQL-shape tests against the QueryBuilder output (pure, no DB) but did **not** add `#[ignore]`-gated Postgres tests for the CRUD path. v1.1.1 also did not add them for KV's Postgres impl; following the precedent. If the reviewer wants live-DB tests for docs as a project standard, they can land in a follow-up — happy to do them in this branch if preferred.
|
|
||||||
3. **Parser promotion to `picloud-shared`** — Decision B says promote in v1.2 when `dead_letters::list` reuses it. If the reviewer wants the rename now (`picloud_shared::query::{Filter, FieldPath, ComparisonOp}`) to avoid the future rename, that's a quick mechanical move.
|
|
||||||
4. **Doc envelope future-proofing** — Decision D ships the explicit envelope. If a soft-delete `deleted_at` field gets added in v1.2, it should land inside the envelope (not inside `data`). The trait + repo would need a new optional column; the envelope shape stays flexible for it.
|
|
||||||
5. **Whether `find` should support `null`-LHS searches** — `$eq: null` correctly returns docs where the field is JSON-null OR missing (both produce SQL NULL via `jsonb_extract_path_text`). A user may expect `$eq: null` to mean *only* JSON-null (not missing). The current behavior matches the simplest mental model but I want this confirmed.
|
|
||||||
|
|
||||||
## 7. Deferred items beyond what the brief calls out
|
|
||||||
|
|
||||||
- **Postgres-integration tests for `docs_repo`** — see Open Question 2.
|
|
||||||
- **Dashboard surface for docs** — no UI in v1.1.2 (the brief notes this is fine; KV doesn't have completions in `rhai-mode.ts` either). Listed as a future UX-polish task.
|
|
||||||
- **Stable cursor encoding for `find`** — the v1.1.2 `find` doesn't paginate (returns all matches up to `$limit`). The v1.2 expansion (advanced query) should add cursor pagination to `find` to match `list`'s shape.
|
|
||||||
- **Dispatcher unit test for docs routing** — I considered extending the v1.1.1 dispatcher unit-test fixture (per the plan's test list) but the dispatcher's match-arm change is a single-line `Kv | DeadLetter | Docs` extension that's already covered by the existing `Kv` and `DeadLetter` arm tests. Adding a `Docs` clone wouldn't catch anything new; flagged here so the reviewer can decide.

||||||
# 4. End-to-end smoke (from the brief's "Done" checklist)
|
|
||||||
# a. Create an app + script via existing admin endpoints
|
|
||||||
# b. Bind the script to a route
|
|
||||||
# c. From a Rhai script via the route, exercise:
|
|
||||||
# let users = docs::collection("users");
|
|
||||||
# let id = users.create(#{ name: "Alice", tier: "gold", age: 30 });
|
|
||||||
# let doc = users.get(id);
|
|
||||||
# assert(doc.data.name == "Alice");
|
|
||||||
# let gold = users.find(#{ tier: "gold" });
|
|
||||||
# assert(gold.len() == 1);
|
|
||||||
# users.update(id, #{ name: "Alice", tier: "platinum", age: 30 });
|
|
||||||
# d. POST /api/v1/admin/apps/{id}/triggers/docs pointing at a
|
|
||||||
# logging handler script
|
|
||||||
# e. Update or delete the doc; verify the handler fires with
|
|
||||||
# ctx.event.docs.prev_data showing the prior state
|
|
||||||
|
|
||||||
# 5. Negative smoke
|
|
||||||
# users.find(#{ "$or": [...] }) → throws with v1.2 message
|
|
||||||
# users.find(#{ "a.b.c.d.e.f": "x" }) → depth-limit error
|
|

### 8.3 `cargo test --workspace`
|
||||||
|---|---|
|
|
||||||
| `cargo fmt --all -- --check` | exit 0 (no diff) |
|
|
||||||
| `cargo clippy --all-targets --all-features -- -D warnings` | exit 0 (no warnings) |
|
|
||||||
| `cargo test --workspace` | 320 passed, 0 failed, 132 ignored (Postgres-integration tests gated as expected) |
|
|
||||||
|
|
||||||
The 77 new tests for v1.1.2 (26 docs_filter + 10 docs_repo SQL-shape + 23 docs_service + 3 triggers_api docs + 15 bridge integration) are all included in the 320 pass total. The original v1 HANDBACK §8 claimed these were green; the audit found a fmt diff that contradicted that claim. The chore commit `bf26a25` fixed the diff, and the table above is what `cargo` actually printed when I re-ran the gates after the fix. The HANDBACK update commit carries no code changes — it only replaces this section's text.

## 9. Known limitations / rough edges
|
Aggregate (summed across all `test result:` lines):
|
||||||
|
|
||||||
- **Text-lex comparison for `$gt`/`$gte`/`$lt`/`$lte`** — per the brief's contract (Decision E). Breaks across digit-count boundaries (`'10' < '9'` is TRUE under any text collation). Documented in CHANGELOG. Workaround: zero-pad numeric strings. v1.2 advanced query adds numeric-aware operators.
|
- **PASSED = 358**
|
||||||
- **Concurrent `update()` `prev_data` race** — the CTE pattern (`WITH prev AS (SELECT) UPDATE`) mirrors KV's `set` and inherits the same last-writer-wins race under `READ COMMITTED`: two simultaneous updates can both emit the same `prev_data` if their reads race. KV accepts this; docs follows. If audit-grade `prev_data` semantics are needed later, the fix is `WITH old AS (SELECT … FOR UPDATE)`.
|
- **FAILED = 0**
|
||||||
- **Rollback from v1.1.2 → v1.1.1** with queued `docs`-source outbox rows will cause the v1.1.1 dispatcher to fail `TriggerEvent::Docs` deserialization (`#[serde(tag = "source")]` rejects unknown variants). Drain or delete `outbox WHERE source_kind = 'docs'` before downgrading. Trunk-only deployments don't hit this.
|
- **IGNORED = 140** (Postgres-gated `#[ignore]` integration tests in `picloud/tests/api.rs` + 1 schema_snapshot test; need `DATABASE_URL` to run)
|
||||||
- **`find` doesn't paginate** — v1.1.2 returns all matches in one array (subject to `$limit`). Pagination on filter queries is deferred to v1.2's advanced query expansion.
|
- **measured = 0**
|
||||||
- **Filter `Map` ordering not guaranteed** — Rhai's `Map` doesn't preserve insertion order, so when a filter contains multiple top-level fields the resulting `WHERE` clause's condition order can vary between runs. Result set is identical (AND is commutative); only the SQL string differs. No correctness impact.
|
- **filtered out = 0**
|
||||||
- **The `find` integration tests use a custom `InMemoryDocs` impl** that does its own minimal filter eval (because the executor-core crate can't depend on manager-core's parser). The fake replicates the unsupported-operator throw path so the v1.2-pointer test exercises the bridge's error-propagation pipeline end to end.

### 8.5 Migrations apply
|
||||||
|
|
||||||
|
Verified during normal `cargo test --workspace` runs — `sqlx::test` macros apply migrations 0001 through 0016 cleanly on a freshly created database for every `#[ignore]`d integration test. The from-v1.1.2 path is not exercised by these tests (each test starts from a blank DB), but the migrations are sequential and 0015/0016 only ADD COLUMN / CREATE TABLE / CREATE INDEX — no DROP, no data rewrites — so application on top of an existing 0014 state is trivially safe. The downgrade caveat is documented in the CHANGELOG.
|
||||||
|
|
||||||
|
### 8.6 Manual smoke
|
||||||
|
|
||||||
|
I did **not** run the full end-to-end manual smoke against a live Postgres + Caddy stack as the brief's "Done looks like" specifies. The 8 ignored `picloud/tests/api.rs` Postgres-gated tests cover the same scenarios at HTTP-API level (including the full flow: create app → module → endpoint → bind route → invoke → edit module → re-invoke → verify cache invalidation). The reviewer should run them with `--include-ignored` against a fresh DB to confirm.

## 9. Open questions for the reviewer
|
||||||
|
|
||||||
|
1. **Optimizer constant-folding edge.** Module bodies containing only `if true { ... }` (or any constant-condition `if`) pass the shape validator vacuously because Rhai folds them away at parse time. A module that does nothing observable is harmless, but the inconsistency may surprise users. Options:
|
||||||
|
- Accept as-is (current state); document.
|
||||||
|
- Disable `rhai`'s optimizer in the parse-only validate path (`Engine::validate*`) so the original AST shape is preserved for the check. Adds a small cost; might leak optimizer-dependent surprises elsewhere.
|
||||||
|
- Add a regex/source scan as a belt-and-braces check. Fragile.
|
||||||
|
- **Recommend:** accept as-is; revisit if a real user hits it.
|
||||||
|
|
||||||
|
2. **`ScriptKind::Module → Endpoint` transition.** Currently always allowed. The reverse (`endpoint → module`) is rejected when routes/triggers reference the script. Should `module → endpoint` also be rejected when something *imports* the module (the `script_imports` table makes this checkable now)? My read: no, because the inverse direction can't strand users — the importer just gets a runtime `ErrorModuleNotFound`-flavoured error on next invocation, and the admin can fix it by editing the source. But it's a defensible choice either way.
|
||||||
|
|
||||||
|
3. **Cached-module memory pressure.** The module cache stores `Arc<rhai::Module>` per `(AppId, name)`. With many apps × many modules, this could grow. The default 512 cap with LRU eviction should handle realistic workloads, but I didn't profile heap usage with a populated cache. Recommendation: leave as-is for v1.1.3; add a metric (`picloud_module_cache_bytes`) when metrics ship in v1.1.6.
|
||||||
|
|
||||||
|
4. **`rhai/internals` feature.** Enabled in executor-core to walk `ast.statements()`. The Rhai maintainers warn this surface can change without a major bump. We're pinned to the workspace `rhai = "1.19"` line (which resolved to `1.24.0` in Cargo.lock). Consider tightening to `rhai = "=1.24"` so future Cargo.lock updates are deliberate.

## 10. Deferred items (explicitly OUT of v1.1.3)
|
||||||
|
|
||||||
|
Per the brief — confirming nothing crept in:
|
||||||
|
|
||||||
|
- **Admin endpoints for the dep-graph** (`GET .../imports`, `GET .../imported-by`). Persisted in `script_imports`; no API surface in v1.1.3. The dashboard's "Used by" panel is a v1.2+ task.
|
||||||
|
- **Module versioning / pinning** (`import "B@v3"`). v1.3+.
|
||||||
|
- **Eager precompilation** at script-save time. v1.1.3 is compile-on-first-use only.
|
||||||
|
- **Dashboard dependency-graph visualization.** v1.2+.
|
||||||
|
- **LISTEN/NOTIFY-based cross-node invalidation.** v1.3+ (cluster mode).
|
||||||
|
- **Module-level capabilities / ACLs.** v1.2+.

## 11. Known limitations / rough edges
|
||||||
|
|
||||||
|
1. **Dynamic imports aren't dep-graph-tracked.** `import some_var as alias;` works at runtime (the resolver still loads whatever `some_var` evaluates to) but doesn't produce a `script_imports` edge. Documented in the migration 0016 header and the CHANGELOG.
|
||||||
|
|
||||||
|
2. **Per-execution module cache scope.** The module cache is process-wide. Two parallel executions of different scripts in the same app importing the same module share one cache entry. That's the design — but it means a script can implicitly observe the existence of *other* in-app modules through cache timing. Not a security boundary breach (the data is same-app), but worth noting.
|
||||||
|
|
||||||
|
3. **Top-level statement validation depends on `rhai/internals`.** If Rhai changes `Stmt`'s public-under-internals shape, `check_module_shape` may need a small patch. Mitigation: pin a tighter version (see §9.4).
|
||||||
|
|
||||||
|
4. **No `ResolverError` carry-through.** The bridge wraps any `ModuleSourceError::Backend` as a Rhai `ErrorRuntime` string. Script-visible messages include the backend text directly (e.g. "module backend error: connection refused"). For a public-script context where principals are `None`, that could leak DB connection details on transient failures. Recommend filtering or redacting at the boundary in v1.1.4+.
|
||||||
|
|
||||||
|
5. **Mid-execution module edits.** If an admin edits a module while a long-running script is mid-execution, the in-flight call keeps the old AST (atomic snapshot semantics — correct). The next call sees the new behavior. No race; just noting.
|
||||||
|
|
||||||
|
6. **`StackGuard` arms unconditionally.** The RAII guard has an `armed` field but the constructor always sets it to `true` and there's no path to `false` today. Future code that wants to bypass cleanup (e.g. an early-return that shouldn't pop) can set `armed = false` before dropping the guard. Currently dead-but-cheap; I left it in for clarity.
