The existing `run_view_definition_handler` in `crates/sof/src/handlers.rs` is the migration source for `$viewdefinition-run` but cannot be copied verbatim — it is coupled to `crates/sof`'s own error types (`ServerError`) and models, and must be adapted to `helios-rest`'s `AppState` and `OperationOutcome` error patterns. + +#### Phase 3 — ExportController Trait + +The entire `crates/rest/src/sof/` module directory does not exist. All four planned files need to be created from scratch. `dashmap` is not currently a dependency of `crates/rest` and must be added as optional under the `sof` feature. + +#### Phase 4 — $viewdefinition-export Handlers + +`crates/rest/src/handlers/sof/` does not exist. Depends on Phase 3. + +#### Phase 5 — $sqlquery-run Handler + +`crates/sof/src/sqlquery.rs` does not exist. DataFusion is the largest new dependency in the plan and is entirely absent from the workspace. This is the highest-risk phase. + +#### Phase 6 — CapabilityStatement Updates + +`crates/rest/src/handlers/capabilities.rs` exists but has no `#[cfg(feature = "sof")]` blocks or SOF operation entries. + +--- + +### Issues Requiring Resolution Before Implementation + +1. **`process_view_definition_generic` is private** — The plan references this function for Phase 4/5. It must be made `pub` or `pub(crate)` before it can be called from `crates/rest`. Alternative: use the public `process_view_definition` with minor API adaptation. + +2. **SQL engine for Phase 5 is unconfirmed** — See Open Clarifying Questions above. DataFusion is absent from the workspace; adding it is a significant step. + +3. **Cursor key alignment for `StreamingProvider`** — The plan proposes ordering by `id` alone. The existing keyset cursor uses a composite `last_updated + id` key. The `StreamingProvider` implementation should align with the existing pattern. + +4. **`dashmap` missing from `crates/rest`** — Required for `InMemoryExportController`. Must be added as an optional dependency under the `sof` feature. + +5. **`$viewdefinition-run` migration is non-trivial** — The handler in `crates/sof/src/handlers.rs` uses `crates/sof`'s `ServerError`, `RunQueryParams`, `ValidatedRunParams`, and `SofParameters` types. Migrating it into `crates/rest` requires rewriting the error mapping and parameter extraction to match `helios-rest` conventions.

8bit Implements the full SQL-on-FHIR v2 IG against the HFS FHIR server. ## Persistence layer - `SofRunner` trait + `ViewFilters` (since, patient, group, limit) in `helios-persistence::core::sof_runner` - `RawSqlRunner` trait for `$sql-query-run` in `core::raw_sql` - SQLite in-DB runner (`SqliteInDbRunner`): compiles ViewDefinitions to parameterised SQL via `compiler.rs`; supports flat columns, forEach, forEachOrNull, unionAll, and runtime filter injection - PostgreSQL in-DB runner (`PostgresInDbRunner`): same compiler, JSONB operators, streaming via `tokio::sync::mpsc` + `spawn_blocking` - `inject_before_order_by` bug fix: compiler emits `\nORDER BY` but both runners searched for ` ORDER BY`; filter conditions were appended after the ORDER BY clause and silently ignored — fixed in both dialects - Auto-fallback: backends expose `sof_runner()` returning `Option>`; `Uncompilable` views fall back to `InProcessRunner` - Integration tests: `sof_sqlite_runner.rs`, `sof_pg_runner.rs` ## REST layer - `InProcessRunner`: universal FHIRPath fallback backed by `SearchProvider` - `$viewdefinition-run` handler: NDJSON / JSON / CSV / Parquet output, `_since` / `patient` / `group` / `_limit` filters, `X-HFS-Runner` header, auto-fallback on `Uncompilable` (`HFS_SOF_DEFAULT_RUNNER=auto`) - `$viewdefinition-export` handler: async job submission (POST), polling (GET), cancellation (DELETE), shard download; backed by `ExportJobController` trait - `InMemoryController` + `InMemorySink`: in-process export with DashMap job registry, Semaphore concurrency cap, row sharding via `planner` - Parquet export fix: `format_rows` was missing the `"parquet"` arm in `InMemoryController`, silently returning NDJSON bytes in `.parquet` shards - `$sql-query-run` handler: tenant-scoped raw SELECT via `RawSqlRunner`, DDL/DML blocked by `sqlparser` validation - `/$sql-on-fhir-capabilities` handler: CapabilityStatement for SoF ops - `HFS_SOF_DEFAULT_RUNNER` env var; capabilities, routing, AppState wired ## Tests Handler-level integration tests (no Docker required): - `sof_run.rs`: happy path, formats, limit, error cases, runner override, filter tests (_since / patient / group), auto-fallback test - `sof_export.rs`: submit→poll→download, cancel, multi-shard, Parquet magic - `sof_capabilities.rs`: CapabilityStatement shape - `sof_sql_query.rs` / `sof_sql_query_sqlite.rs`: raw SQL execution SoF v2 official conformance suite: - Vendored 22 fixture files from `FHIR/sql-on-fhir-v2/tests/` into `crates/rest/tests/conformance/sof_v2/` - `sof_conformance.rs`: 125 pass, 9 skipped (`%rowIndex` not yet implemented), 0 fail; runs on every PR, no Docker --- Cargo.lock | 61 + Cargo.toml | 4 +

The existing `run_view_definition_handler` in `crates/sof/src/handlers.rs` is the migration source for `$viewdefinition-run` but cannot be copied verbatim — it is coupled to `crates/sof`'s own error types (`ServerError`) and models, and must be adapted to `helios-rest`'s `AppState` and `OperationOutcome` error patterns. - -#### Phase 3 — ExportController Trait - -The entire `crates/rest/src/sof/` module directory does not exist. All four planned files need to be created from scratch. `dashmap` is not currently a dependency of `crates/rest` and must be added as optional under the `sof` feature. - -#### Phase 4 — $viewdefinition-export Handlers - -`crates/rest/src/handlers/sof/` does not exist. Depends on Phase 3. - -#### Phase 5 — $sqlquery-run Handler - -`crates/sof/src/sqlquery.rs` does not exist. DataFusion is the largest new dependency in the plan and is entirely absent from the workspace. This is the highest-risk phase. - -#### Phase 6 — CapabilityStatement Updates - -`crates/rest/src/handlers/capabilities.rs` exists but has no `#[cfg(feature = "sof")]` blocks or SOF operation entries. - ---- - -### Issues Requiring Resolution Before Implementation - -1. **`process_view_definition_generic` is private** — The plan references this function for Phase 4/5. It must be made `pub` or `pub(crate)` before it can be called from `crates/rest`. Alternative: use the public `process_view_definition` with minor API adaptation. - -2. **SQL engine for Phase 5 is unconfirmed** — See Open Clarifying Questions above. DataFusion is absent from the workspace; adding it is a significant step. - -3. **Cursor key alignment for `StreamingProvider`** — The plan proposes ordering by `id` alone. The existing keyset cursor uses a composite `last_updated + id` key. The `StreamingProvider` implementation should align with the existing pattern. - -4. **`dashmap` missing from `crates/rest`** — Required for `InMemoryExportController`. Must be added as an optional dependency under the `sof` feature. - -5. **`$viewdefinition-run` migration is non-trivial** — The handler in `crates/sof/src/handlers.rs` uses `crates/sof`'s `ServerError`, `RunQueryParams`, `ValidatedRunParams`, and `SofParameters` types. Migrating it into `crates/rest` requires rewriting the error mapping and parameter extraction to match `helios-rest` conventions. diff --git a/crates/hfs/Cargo.toml b/crates/hfs/Cargo.toml index afeed543e..a0ae4c53e 100644 --- a/crates/hfs/Cargo.toml +++ b/crates/hfs/Cargo.toml @@ -15,7 +15,7 @@ name = "hfs" path = "src/main.rs" [features] -default = ["R4", "sqlite"] +default = ["R4", "sqlite", "sof"] # FHIR version features R4 = ["helios-fhir/R4", "helios-rest/R4"] @@ -33,6 +33,9 @@ mongodb = ["helios-rest/mongodb"] elasticsearch = ["helios-rest/elasticsearch"] s3 = ["helios-rest/s3"] +# SQL-on-FHIR (on by default) +sof = ["helios-rest/sof"] + # Auth backends redis = ["helios-rest/redis", "helios-auth/redis"] @@ -43,8 +46,15 @@ reqwest = { version = "0.12", features = ["blocking"] } helios-fhir = { path = "../fhir", version = "0.1.47" } helios-rest = { path = "../rest", version = "0.1.47", default-features = false } helios-persistence = { path = "../persistence", version = "0.1.47", default-features = false } +helios-sof = { path = "../sof", version = "0.1.47", default-features = false } helios-auth = { path = "../auth", version = "0.1.47" } +# Export job controller +dashmap = "6" + +# SQL query DDL rejection +sqlparser = "0.54" + # Web framework axum = "0.8" diff --git a/crates/persistence/src/backends/postgres/backend.rs b/crates/persistence/src/backends/postgres/backend.rs index 279d37337..2bf40fb9e 100644 --- a/crates/persistence/src/backends/postgres/backend.rs +++ b/crates/persistence/src/backends/postgres/backend.rs @@ -479,6 +479,13 @@ impl PostgresBackend { &self.config } + /// Returns a clone of the underlying connection pool. + /// + /// `deadpool_postgres::Pool` is `Clone` (Arc-backed), so this is cheap. + pub(crate) fn pool(&self) -> Pool { + self.pool.clone() + } + /// Returns a reference to the search parameter registry. pub fn search_registry(&self) -> &Arc> { &self.search_registry diff --git a/crates/persistence/src/backends/postgres/storage.rs b/crates/persistence/src/backends/postgres/storage.rs index 13af28927..9df416ba9 100644 --- a/crates/persistence/src/backends/postgres/storage.rs +++ b/crates/persistence/src/backends/postgres/storage.rs @@ -48,6 +48,11 @@ impl ResourceStorage for PostgresBackend { "postgres" } + fn sof_runner(&self) -> Option> { + use crate::sof::postgres::PgInDbRunner; + Some(std::sync::Arc::new(PgInDbRunner::new(self.pool()))) + } + async fn create( &self, tenant: &TenantContext, diff --git a/crates/persistence/src/backends/sqlite/backend.rs b/crates/persistence/src/backends/sqlite/backend.rs index 98f9bd58f..0e4ad1252 100644 --- a/crates/persistence/src/backends/sqlite/backend.rs +++ b/crates/persistence/src/backends/sqlite/backend.rs @@ -369,6 +369,11 @@ impl SqliteBackend { Ok(count) } + /// Returns a clone of the connection pool (cheap — pool is `Arc`-backed internally). + pub(crate) fn pool(&self) -> Pool { + self.pool.clone() + } + /// Get a connection from the pool. pub(crate) fn get_connection( &self, diff --git a/crates/persistence/src/backends/sqlite/storage.rs b/crates/persistence/src/backends/sqlite/storage.rs index 28cfebb39..ba4164087 100644 --- a/crates/persistence/src/backends/sqlite/storage.rs +++ b/crates/persistence/src/backends/sqlite/storage.rs @@ -49,6 +49,11 @@ impl ResourceStorage for SqliteBackend { "sqlite" } + fn sof_runner(&self) -> Option> { + use crate::sof::sqlite::SqliteInDbRunner; + Some(std::sync::Arc::new(SqliteInDbRunner::new(self.pool()))) + } + async fn create( &self, tenant: &TenantContext, diff --git a/crates/persistence/src/core/backend.rs b/crates/persistence/src/core/backend.rs index 7ae1e1e1e..df52527a4 100644 --- a/crates/persistence/src/core/backend.rs +++ b/crates/persistence/src/core/backend.rs @@ -106,6 +106,10 @@ pub enum BackendCapability { SchemaPerTenant, /// Database-per-tenant multitenancy.

The `sof` feature was on by default in both `helios-rest` and `helios-hfs` and gated nothing useful: `helios-sof` was already an unconditional dependency of both crates, `sqlparser` was already non-optional in `helios-hfs`, and no documented or CI path turned the feature off. Removing it strips ~80 `#[cfg(feature = "sof")]` attributes plus a no-op `create_sof_routes()` fallback and aligns the source with how the server is actually shipped. Changes: - Drop `sof` from `default = [...]` and delete the feature definitions in `crates/rest/Cargo.toml` and `crates/hfs/Cargo.toml`. - Promote `sqlparser` to a non-optional dep in `helios-rest` (matches `helios-hfs`, which was already non-optional). - Strip all `#[cfg(feature = "sof")]` / `#[cfg(not(feature = "sof"))]` attributes from `crates/rest/src/{config,state,lib}.rs`, `handlers/{mod,capabilities}.rs`, `handlers/sof/run.rs`, `routing/fhir_routes.rs`, and the 6 `tests/sof_*.rs` files. - Delete the no-op `create_sof_routes()` fallback in `fhir_routes.rs`. - Tidy stale doc comments referencing "when the feature is enabled". - Add the missing `tokio-stream` dep to `helios-persistence` (pre-existing build break: `crates/persistence/src/sof/{sqlite, postgres}.rs` import `tokio_stream::wrappers::ReceiverStream` but the crate never declared the dep). Out-of-tree impact: anyone previously building with `--no-default-features --features R4,sqlite` (deliberately excluding `sof`) will now silently get SOF compiled in. --- Cargo.lock | 1 - crates/hfs/Cargo.toml | 5 +-- crates/persistence/Cargo.toml | 1 + crates/rest/Cargo.toml | 9 ++--- crates/rest/src/config.rs | 42 ----------------------- crates/rest/src/handlers/capabilities.rs | 36 ++++++++----------- crates/rest/src/handlers/mod.rs | 1 -

Security - Tenant auth on export status/cancel/download — guessable job IDs no longer cross tenant boundaries; mismatched tenants get 404 (not 403) to avoid leaking existence. - Parameter binding for $sqlquery-run (spec MUST): :name placeholders are rewritten to driver-native positional binds; values are bound via ToSql / rusqlite params, never interpolated. New BoundValue enum covers Bool/Int/Decimal/Text/Date/DateTime/Null. Interop - $sqlquery-run URL renamed to spec spelling /$sqlquery-run with Library type-/instance-level routes. - Export completion manifest uses spec field names (exportId, status, location, cancelUrl, _format, exportStartTime, exportEndTime, exportDuration) and grouped output.part entries (name/location/rowCount). - /metadata advertises viewdefinition-run unconditionally and gates viewdefinition-export / sqlquery-run on runtime wiring. - Async export uses the 303 → result-URL pattern: status URL returns 303 See Other to /_operations/export/{id}/$result on completion. - Prefer: respond-async is required at export kickoff (400 otherwise). - DELETE cancellation returns 202 Accepted (was 204). - Retry-After: 5 on running polls. Functional - viewReference (relative form ViewDefinition/{id}) accepted in run + export; canonical / absolute rejected with descriptive 400 and disclosed in $sql-on-fhir-capabilities. - Stored ViewDefinition lookup at /ViewDefinition/{id}/$viewdefinition-run reads from storage instead of the prior Phase-1 stub. - Body-level parameters (_format, _limit, _since, patient, group, header) parsed from Parameters bodies with body-over-query precedence. - Inline resource[] in Parameters body drives the in-process runner directly, bypassing storage. - Multi-value patient/group (spec 0..*): ViewFilters fields are now Vec; runners expand to OR clauses; handlers accept comma-separated query values and repeated Parameters entries. - view[] multi-view export: ExportTask carries Vec, manifest emits one output entry per view with view.name in output.part. - clientTrackingId accepted at submit and echoed in the manifest. - _format=json and header on export. - _format=fhir on $sqlquery-run returns a FHIR Parameters resource per the spec SQL→FHIR type table; composite types return 422. - $viewdefinition-run streams NDJSON responses (Body::from_stream over a tokio mpsc bridge) so large views don't have to buffer fully; RowStream is now 'static. Tests - sof_run: viewReference (relative + canonical-rejected), inline resources, multi-value patient filter. - sof_export: manifest field conformance, tenant isolation, Prefer enforcement, clientTrackingId echo, json format, multi-view. - sof_sql_query_sqlite: parameter binding happy path, SQL-injection regression, missing-value 400, _format=fhir.

Both pass the full SQL-on-FHIR v2 conformance corpus (125/125 fixtures). Compiler / IR - Two-stage IR: PlanNode (scan / lateral-unnest / filter / project / union / recurse) + SqlExpr (json-path / cast / binop / case / scalar-from-chain / collection-agg / where-scalar / where-exists / reference-key / boundary). - Dialect trait abstraction (PgDialect, SqliteDialect) for placeholders, json navigation, json_agg, casts, regex. - compile_path lowers FHIRPath to SqlExpr; compile_view assembles the PlanNode tree per ViewDefinition. PostgreSQL - New PgInDbRunner streams rows via tokio_postgres::query_raw + bounded mpsc channel. - Type-aware comparisons / arithmetic — text JSON projections need ::numeric / 'true'-'false' literals to type-check under PG strict typing. - jsonb_typeof type-guards on every unnest source so FHIR singletons (object-shaped contact.name) wrap into one-element arrays. - coalesce(jsonb_agg(...), '[]'::jsonb) for empty collection columns. - Recursive CTE: split seed vs step branches and fold multi-path steps into a single lateral so rec_0 is referenced once (PG requirement). Recursive UNION ALL branches get _recurse_N aliases. - Boolean / Int / Decimal constants bound as text strings so they compare cleanly against ->> JSON-text projections; explicit ::numeric casts in arithmetic / ordering contexts. SQLite - json_each / json_extract / json_type chains with json_array(json(X)) type-guards for singleton object navigation. - Custom UDFs (sqlite_udfs.rs) for fhir_last_segment. Conformance - crates/rest/tests/sof_conformance.rs (SQLite, PASS_FLOOR=125) and crates/rest/tests/sof_conformance_postgres.rs (PG, PG_PASS_FLOOR=125) drive every fixture through the live HTTP endpoint. - The PG suite uses the same testcontainers + github.run_id labelling pattern as the existing PG integration tests; CI's self-hosted runner has Docker available, so it runs alongside everything else. - Conformance fixtures consumed from crates/sof/tests/sql-on-fhir-v2/ (the local copy under crates/rest/tests/conformance/ is removed). Removes the in-memory in_process runner and its module wiring. --- Cargo.lock | 2 + crates/fhirpath/src/lib.rs | 30 +- crates/persistence/Cargo.toml | 2 +- .../src/backends/sqlite/backend.rs | 11 + crates/persistence/src/sof/compile_path.rs | 982 ++++++++++- crates/persistence/src/sof/compile_view.rs | 997 ++++++++++- crates/persistence/src/sof/compiler.rs | 1101 +++--------- crates/persistence/src/sof/dialect.rs | 92 +- crates/persistence/src/sof/emit.rs | 1563 ++++++++++++++++- crates/persistence/src/sof/inline.rs | 73 + crates/persistence/src/sof/ir.rs | 99 ++ crates/persistence/src/sof/mod.rs | 6 + crates/persistence/src/sof/postgres.rs | 78 +- crates/persistence/src/sof/sqlite.rs | 102 +- crates/persistence/src/sof/sqlite_udfs.rs | 44 + crates/persistence/tests/sof_pg_runner.rs | 80 +- crates/persistence/tests/sof_sqlite_runner.rs | 578 +++++- crates/rest/Cargo.toml | 6 + crates/rest/src/config.rs | 9 +- crates/rest/src/handlers/sof/run.rs | 120 +- crates/rest/src/lib.rs | 41 +- crates/rest/src/sof/in_process.rs | 301 ---- crates/rest/src/sof/mod.rs | 5 - crates/rest/src/state.rs | 7 +- .../rest/tests/conformance/sof_v2/basic.json | 496 ------ .../tests/conformance/sof_v2/collection.json | 244 --- .../conformance/sof_v2/combinations.json | 256 --- .../tests/conformance/sof_v2/constant.json | 331 ---- .../conformance/sof_v2/constant_types.json | 1032 ----------- .../tests/conformance/sof_v2/fhirpath.json | 412 ----- .../conformance/sof_v2/fhirpath_numbers.json | 103 -- .../tests/conformance/sof_v2/fn_boundary.json | 362 ---- .../tests/conformance/sof_v2/fn_empty.json | 57 - .../conformance/sof_v2/fn_extension.json | 173 -- .../tests/conformance/sof_v2/fn_first.json | 77 - .../tests/conformance/sof_v2/fn_join.json | 106 -- .../tests/conformance/sof_v2/fn_oftype.json | 111 -- .../conformance/sof_v2/fn_reference_keys.json | 109 -- .../tests/conformance/sof_v2/foreach.json | 832 --------- .../rest/tests/conformance/sof_v2/logic.json | 125 -- .../rest/tests/conformance/sof_v2/repeat.json | 519 ------ .../tests/conformance/sof_v2/row_index.json | 698 -------- .../rest/tests/conformance/sof_v2/union.json | 842 --------- .../tests/conformance/sof_v2/validate.json | 99 -- .../conformance/sof_v2/view_resource.json | 95 - .../rest/tests/conformance/sof_v2/where.json | 279 --- crates/rest/tests/sof_conformance.rs | 48 +- crates/rest/tests/sof_conformance_postgres.rs | 472 +++++ crates/rest/tests/sof_run.rs | 105 +- 49 files changed, 5417 insertions(+), 8895 deletions(-) create mode 100644 crates/persistence/src/sof/inline.rs create mode 100644 crates/persistence/src/sof/sqlite_udfs.rs delete mode 100644 crates/rest/src/sof/in_process.rs delete mode 100644 crates/rest/src/sof/mod.rs delete mode 100644 crates/rest/tests/conformance/sof_v2/basic.json delete mode 100644 crates/rest/tests/conformance/sof_v2/collection.json delete mode 100644 crates/rest/tests/conformance/sof_v2/combinations.json delete mode 100644 crates/rest/tests/conformance/sof_v2/constant.json delete mode 100644 crates/rest/tests/conformance/sof_v2/constant_types.json delete mode 100644 crates/rest/tests/conformance/sof_v2/fhirpath.json delete mode 100644 crates/rest/tests/conformance/sof_v2/fhirpath_numbers.json delete mode 100644 crates/rest/tests/conformance/sof_v2/fn_boundary.json delete mode 100644 crates/rest/tests/conformance/sof_v2/fn_empty.json delete mode 100644 crates/rest/tests/conformance/sof_v2/fn_extension.json delete mode 100644 crates/rest/tests/conformance/sof_v2/fn_first.json delete mode 100644 crates/rest/tests/conformance/sof_v2/fn_join.json delete mode 100644 crates/rest/tests/conformance/sof_v2/fn_oftype.json delete mode 100644 crates/rest/tests/conformance/sof_v2/fn_reference_keys.json delete mode 100644 crates/rest/tests/conformance/sof_v2/foreach.json delete mode 100644 crates/rest/tests/conformance/sof_v2/logic.json delete mode 100644 crates/rest/tests/conformance/sof_v2/repeat.json delete mode 100644 crates/rest/tests/conformance/sof_v2/row_index.json delete mode 100644 crates/rest/tests/conformance/sof_v2/union.json delete mode 100644 crates/rest/tests/conformance/sof_v2/validate.json delete mode 100644 crates/rest/tests/conformance/sof_v2/view_resource.json delete mode 100644 crates/rest/tests/conformance/sof_v2/where.json create mode 100644 crates/rest/tests/sof_conformance_postgres.rs diff --git a/Cargo.lock b/Cargo.lock index 05eb1439c..77e8d8323 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -2996,6 +2996,8 @@ dependencies = [ "serde_json", "sqlparser", "tempfile", + "testcontainers", + "testcontainers-modules", "thiserror 2.0.18", "tokio", "tokio-test", diff --git a/crates/fhirpath/src/lib.rs b/crates/fhirpath/src/lib.rs index 917f2e71e..d9e890b7e 100644 --- a/crates/fhirpath/src/lib.rs +++ b/crates/fhirpath/src/lib.rs @@ -353,10 +353,26 @@ pub fn evaluate_expression( expression: &str, context: &EvaluationContext, ) -> Result { + let parsed = parse_expression(expression)?;

Net diff: -388 lines. Phase A — REST output formatters helios-sof: promote `format_output`/`format_csv`/`format_json`/ `format_ndjson`/`format_parquet` to `pub`, add `rows_to_processed_result`. helios-rest: delete `stream_to_csv`/`stream_to_json_array`/ `stream_to_ndjson`/`stream_to_parquet` (~165 lines of hand-rolled CSV escaping, Parquet schema inference, and JSON object building). `format_stream` now drains the `RowStream` once and dispatches through the shared formatters. The streaming NDJSON `mpsc` path is unchanged (it's the only true streaming path). Adds a small `content_type_headers` helper to deduplicate the two header-mapping sites. Phase B — Shared `constant[]` parsing helios-sof: new `constants.rs` with `ConstantValue` enum + `parse_constant_from_json` + `ConstantValue::to_evaluation_result`. The four per-version `ViewDefinitionConstantTrait::to_evaluation_result` impls in `traits.rs` (~110 lines each, including `@`/`@T` prefixing and decimal precision handling) collapse to a small per-version mapping into the neutral `ConstantValue` plus a delegated call. Fixes an R6 bug where `Integer64` was downcasting to `Integer`. helios-persistence: gains a `helios-sof` dep (FHIR-version features pass through). `populate_constants` in `compile_view.rs` delegates the `value[X]` field walk to the shared parser, then lifts `ConstantValue` into the compiler's `LitValue`. Phase C — Shared Parameters extractor helios-sof: new `params.rs` with `ExtractedRunParams` + `extract_run_params_from_json` + `body_has_view_definition`. Single source of truth for the `_format`/`_limit`/`_since`/`patient`/`group`/ `viewResource`/`viewReference`/`resource`/`header`/Parquet-options field list and their accepted JSON shapes. Accepts both raw JSON and FHIR-typed serde output (`name` as string or `{value: ...}`). helios-rest: `BodyParams`, `extract_body_params`, `body_has_view`, and the inline body-walking in `resolve_view_from_body` are gone — `run.rs` uses the shared extractor end-to-end (~155 lines removed). helios-sof: `extract_all_parameters` in `models.rs` keeps its strict validation pass (`_limit` bounds, RFC 3339 `_since`, `compression` allowed values, `header` boolean shape) that REST didn't have; doc comment notes the relationship and future-convergence path.

The walker tracks the current parent FHIR type starting from `ViewDefinition.resource`, looking up each segment's `(type, is_collection)` pair, and returns true when any non-terminal segment crosses a `0..*` element. Opaque segments (function calls, brackets) and unknown fields short-circuit to "no info" rather than guess. `build_plan` and `compile_view_definition_dialect` take a `FhirVersion` argument; `SqliteInDbRunner` / `PgInDbRunner` carry the version (default R4) with a `with_fhir_version` builder. --- crates/persistence/src/sof/compile_path.rs | 26 ++++++ crates/persistence/src/sof/compile_view.rs | 100 ++++++++++++++------- crates/persistence/src/sof/compiler.rs | 15 +++- crates/persistence/src/sof/postgres.rs | 24 ++++- crates/persistence/src/sof/sqlite.rs | 24 ++++- 5 files changed, 147 insertions(+), 42 deletions(-) diff --git a/crates/persistence/src/sof/compile_path.rs b/crates/persistence/src/sof/compile_path.rs index 9dd2a9a3b..0e4f2f3b3 100644 --- a/crates/persistence/src/sof/compile_path.rs +++ b/crates/persistence/src/sof/compile_path.rs @@ -21,6 +21,7 @@ use std::collections::HashMap; +use helios_fhir::FhirVersion; use helios_fhirpath::parse_expression; use helios_fhirpath::parser::{Expression, Invocation, Literal, Term, TypeSpecifier}; @@ -59,6 +60,15 @@ pub struct CompileEnv { /// Distinct from the plan-level `AliasSeq` so expression-internal /// aliases never collide with `forEach` / `repeat` aliases. pub next_where_alias: usize, + /// Root FHIR resource type the ViewDefinition runs over (the + /// `ViewDefinition.resource` value).

Now any value[A-Z]* key is accepted, restoring valueQuantity / valueReference / valueDateTime / etc. for FHIRPath patches. - polymorphic_access::is_choice_element no longer always returns false in the no-context path; it consults the default version's FIELD_TYPES so common polymorphic bases (value, effective, onset, …) resolve correctly. - evaluator::could_be_typed_polymorphic_field now answers authoritatively via get_field_type when the parent resourceType is known, falling back to the suffix-validity heuristic only when the parent is unknown. - polymorphic_access::get_polymorphic_fields enumerates the spec-declared typed variants for the resource's parent type and intersects with the JSON keys present, instead of relying purely on a prefix scan that can match unrelated fields. Refactor cleanups: - The duplicated FhirVersion-dispatch wrappers in persistence/sof/mod.rs and fhirpath/type_inference.rs are now thin aliases to the canonical helios_fhir helpers. - fhirpath/fhir_type_hierarchy.rs replaces its HashSet of primitive names (and the buggy full-lowercase normalization that missed dateTime, base64Binary, positiveInt, unsignedInt) with a call to helios_fhir::is_primitive_type. type_inference::is_system_primitive delegates the FHIR-primitive arms similarly. --- crates/fhir/src/lib.rs | 92 ++++++++++++++ crates/fhirpath/src/evaluator.rs | 61 +++------ crates/fhirpath/src/fhir_type_hierarchy.rs | 51 +++----- crates/fhirpath/src/polymorphic_access.rs | 118 +++++++++++++----- crates/fhirpath/src/type_inference.rs | 64 ++-------- .../src/backends/postgres/storage.rs | 24 ++-- .../src/backends/sqlite/storage.rs | 25 ++-- crates/persistence/src/sof/mod.rs | 45 ++----- 8 files changed, 263 insertions(+), 217 deletions(-) diff --git a/crates/fhir/src/lib.rs b/crates/fhir/src/lib.rs index 834cc4ee7..73e50042a 100644 --- a/crates/fhir/src/lib.rs +++ b/crates/fhir/src/lib.rs @@ -1850,6 +1850,98 @@ impl FhirVersion { } } +/// Dispatches a field-type lookup to the per-version generated `FIELD_TYPES` +/// table.

Per spec, GET is permitted for simple invocations using viewReference in the query string; viewResource/resource remain POST-only. - Enforce _format as required (1..1). HFS now consults the Accept header per spec precedence (_format > Accept) and returns 400 OperationOutcome when both are missing. The streaming path no longer silently coerces unknown formats to NDJSON. sof-server pre-checks the body, query, and Accept header and returns 400 when none provides a format. - HFS now returns 501 NotImplemented when the source parameter is supplied; previously it was silently dropped. source-based ETL is the province of the stateless sof-server, not the storage-backed HFS. --- crates/rest/src/handlers/sof/run.rs | 184 ++++++++++++++++++++++------ crates/rest/tests/sof_run.rs | 8 +- crates/sof/src/handlers.rs | 31 ++++- crates/sof/src/models.rs | 10 +- crates/sof/src/server.rs | 6 +- 5 files changed, 192 insertions(+), 47 deletions(-) diff --git a/crates/rest/src/handlers/sof/run.rs b/crates/rest/src/handlers/sof/run.rs index db212a758..35b6b41a5 100644 --- a/crates/rest/src/handlers/sof/run.rs +++ b/crates/rest/src/handlers/sof/run.rs @@ -2,12 +2,14 @@ //! //!

The spec defines `$sqlquery-run` as executing a SQLQuery Library profile whose `content` carries base64-encoded SQL, whose `relatedArtifact[type=depends-on]` declares ViewDefinitions to materialize as named tables, and whose `Library.parameter` declares bound `:name` placeholders. Replace the handler end-to-end: - New `helios_sof::sqlquery` module: parses a SQLQuery Library (Library.type validated against LibraryTypesCodes#sql-query; sql-name label regex enforced; required parameter.type; depends-on duplicate-label check; inline VD resources rejected), opens a per-request in-memory rusqlite engine, binds `:name` parameters via native rusqlite parameter binding (no string interpolation), and formats output (csv/json/ndjson/parquet via the shared format_output path; `_format=fhir` derives value[X] from the VD-declared column type, promotes BIGINT inferences to valueInteger64, and rounds valueInstant to millisecond precision). - New REST handler at `crates/rest/src/handlers/sof/sqlquery.rs`: wires the three spec routes (system, type, instance). queryReference and queryResource on the instance route conflict with the path id and are rejected. `source` is out of scope and returns 422. Canonical and relative `Type/{id}` depends-on references both resolve via storage; Library by canonical URL picks the newest by meta.lastUpdated. Dialect selection prefers `application/sql;dialect=sqlite` over bare `application/sql`. SELECT-only validation via sqlparser. Per-request row cap and watchdog-cancelled timeout. - Capability statement advertises `supportsSqlQueryRun=true` and `supportsCanonicalReference=true` unconditionally. Remove the non-conforming implementation and its scaffolding: delete `crates/persistence/src/core/raw_sql.rs` and `crates/persistence/src/raw_sql/`, the `RawSqlRunner` field on AppState, the `HFS_SOF_READONLY_URL` init block, and the four `HFS_SOF_SQL_QUERY_*` config flags. New flags `HFS_SOF_SQLQUERY_MAX_ROWS`, `_MAX_SOURCE_ROWS_PER_VD`, `_MAX_VDS`, and `_TIMEOUT_SECS` replace them. Output deviation: flat formats return raw bytes with the format MIME type rather than a Binary resource. Documented in the handler. Drive-by: update `sof_run.rs` and `sof_conformance.rs` tests to include `_format=ndjson` in URLs that were missing it (broken since the prior commit made `_format` strictly required for `$viewdefinition-run`). --- Cargo.lock | 4 + crates/persistence/src/core/mod.rs | 2 - crates/persistence/src/core/raw_sql.rs | 331 ----------- crates/persistence/src/lib.rs | 1 - crates/persistence/src/raw_sql/mod.rs | 21 - crates/persistence/src/raw_sql/postgres.rs | 222 -------- crates/persistence/src/raw_sql/sqlite.rs | 198 ------- crates/rest/Cargo.toml | 3 + crates/rest/src/config.rs | 47 +- crates/rest/src/handlers/capabilities.rs | 15 +- crates/rest/src/handlers/sof/capability.rs | 16 +- crates/rest/src/handlers/sof/mod.rs | 4 +- crates/rest/src/handlers/sof/sql_query.rs | 508 ----------------- crates/rest/src/handlers/sof/sqlquery.rs | 534 ++++++++++++++++++ crates/rest/src/lib.rs | 37 -- crates/rest/src/state.rs | 18 - crates/rest/tests/sof_capabilities.rs | 18 +- crates/rest/tests/sof_conformance.rs | 2 +- crates/rest/tests/sof_run.rs | 32 +- crates/rest/tests/sof_sql_query.rs | 488 ---------------- crates/rest/tests/sof_sql_query_sqlite.rs | 512 ----------------- crates/rest/tests/sof_sqlquery.rs | 627 +++++++++++++++++++++ crates/sof/Cargo.toml | 3 + crates/sof/src/lib.rs | 6 + crates/sof/src/sqlquery/bind.rs | 322 +++++++++++ crates/sof/src/sqlquery/engine.rs | 502 +++++++++++++++++ crates/sof/src/sqlquery/library.rs | 489 ++++++++++++++++ crates/sof/src/sqlquery/mod.rs | 63 +++ crates/sof/src/sqlquery/output.rs | 309 ++++++++++ crates/sof/src/sqlquery/params.rs | 142 +++++ 30 files changed, 3071 insertions(+), 2405 deletions(-) delete mode 100644 crates/persistence/src/core/raw_sql.rs delete mode 100644 crates/persistence/src/raw_sql/mod.rs delete mode 100644 crates/persistence/src/raw_sql/postgres.rs delete mode 100644 crates/persistence/src/raw_sql/sqlite.rs delete mode 100644 crates/rest/src/handlers/sof/sql_query.rs create mode 100644 crates/rest/src/handlers/sof/sqlquery.rs delete mode 100644 crates/rest/tests/sof_sql_query.rs delete mode 100644 crates/rest/tests/sof_sql_query_sqlite.rs create mode 100644 crates/rest/tests/sof_sqlquery.rs create mode 100644 crates/sof/src/sqlquery/bind.rs create mode 100644 crates/sof/src/sqlquery/engine.rs create mode 100644 crates/sof/src/sqlquery/library.rs create mode 100644 crates/sof/src/sqlquery/mod.rs create mode 100644 crates/sof/src/sqlquery/output.rs create mode 100644 crates/sof/src/sqlquery/params.rs diff --git a/Cargo.lock b/Cargo.lock index c44a7fda4..62192565f 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -3141,6 +3141,7 @@ dependencies = [ "aws-sdk-s3", "axum", "axum-test", + "base64 0.22.1", "chrono", "clap", "dashmap", @@ -3209,6 +3210,7 @@ dependencies = [ "async-trait", "axum", "axum-test", + "base64 0.22.1", "bytes", "chrono", "clap", @@ -3225,8 +3227,10 @@ dependencies = [ "parquet", "rayon", "reqwest", + "rusqlite", "serde", "serde_json", + "sqlparser", "tempfile", "thiserror 1.0.69", "tokio", diff --git a/crates/persistence/src/core/mod.rs b/crates/persistence/src/core/mod.rs index c397f349d..cd741897b 100644 --- a/crates/persistence/src/core/mod.rs +++ b/crates/persistence/src/core/mod.rs @@ -94,7 +94,6 @@ pub mod bulk_export; pub mod bulk_submit; pub mod capabilities; pub mod history; -pub mod raw_sql; pub mod search; pub mod sof_runner; pub mod storage; @@ -123,7 +122,6 @@ pub use history::{ DifferentialHistoryProvider, HistoryEntry, HistoryMethod, HistoryPage, HistoryParams, InstanceHistoryProvider, SystemHistoryProvider, TypeHistoryProvider, }; -pub use raw_sql::{RawSqlError, RawSqlRunner, SqlRow, wrap_with_tenant_cte}; pub use search::{ ChainedSearchProvider, FullSearchProvider, IncludeProvider, MultiTypeSearchProvider, RevincludeProvider, SearchProvider, SearchResult, TerminologySearchProvider, diff --git a/crates/persistence/src/core/raw_sql.rs b/crates/persistence/src/core/raw_sql.rs deleted file mode 100644 index f39fba109..000000000 --- a/crates/persistence/src/core/raw_sql.rs +++ /dev/null @@ -1,331 +0,0 @@ -//!

Query wins on conflict. - Canonical viewReference resolution via SearchProvider (ViewDefinition.url + optional `|version`), in line with the `supportsCanonicalReference` capability advertised by `$sql-on-fhir-capabilities`. - Failed-job result: 200 + Parameters manifest with `status=failed` and an `error` part carrying the OperationOutcome, replacing the bare 500. The spec's status enum includes `failed`; the manifest is the canonical channel for terminal states. - `estimatedTimeRemaining` (valueInteger) on in-progress poll bodies, derived from elapsed time and reported percent. - Unknown parameter rejection: `deny_unknown_fields` on the query struct plus a body parameter allowlist; both surface as 400 OperationOutcome with code `not-supported` and the offending name in `diagnostics`. - Patient/Group reference validation at kick-off: 404 OperationOutcome listing any relative `Patient/{id}` / `Group/{id}` reference that fails to resolve. Absolute external refs are skipped. - Order-robust shard merge in the completion manifest: group locations by `view_name` preserving first-seen order, so a controller emitting files non-contiguously per view still produces one `output` entry per view. Tests: rewires `test_export_failed_status_returns_303_then_failed_manifest` to the new failure shape, plus five new tests covering unknown query/body params, body-form input precedence, query-wins-on-conflict, and missing patient-ref 404. --- Cargo.lock | 1 + crates/rest/Cargo.toml | 1 + crates/rest/src/handlers/sof/export.rs | 598 +++++++++++++++++++++---- crates/rest/tests/sof_export.rs | 213 ++++++++- 4 files changed, 720 insertions(+), 93 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index 62192565f..182e3a0fb 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -3161,6 +3161,7 @@ dependencies = [ "reqwest", "serde", "serde_json", + "serde_urlencoded", "sqlparser", "tempfile", "testcontainers", diff --git a/crates/rest/Cargo.toml b/crates/rest/Cargo.toml index 9d1ca3863..b90768570 100644 --- a/crates/rest/Cargo.toml +++ b/crates/rest/Cargo.toml @@ -60,6 +60,7 @@ mime = "0.3" # Serialization serde.workspace = true serde_json.workspace = true +serde_urlencoded = "0.7" # Error handling thiserror = "2" diff --git a/crates/rest/src/handlers/sof/export.rs b/crates/rest/src/handlers/sof/export.rs index 4e7c433f1..b2344cf10 100644 --- a/crates/rest/src/handlers/sof/export.rs +++ b/crates/rest/src/handlers/sof/export.rs @@ -29,23 +29,47 @@ //! - `404 Not Found` if the job ID is unknown or was cancelled use axum::{ - extract::{Path, Query, State}, + extract::{Path, State}, http::{HeaderMap, HeaderValue, StatusCode, header}, response::{IntoResponse, Response}, }; use helios_persistence::core::ResourceStorage; +use helios_persistence::core::search::SearchProvider; +use helios_persistence::tenant::TenantContext; +use helios_persistence::types::{ + SearchParamType, SearchParameter, SearchPrefix, SearchQuery, SearchValue, +}; use serde::Deserialize; use serde_json::{Value, json}; -use helios_persistence::tenant::TenantContext; - use crate::error::RestError; use crate::export::controller::{ExportTask, JobStatus, NamedView}; use crate::extractors::TenantExtractor; use crate::state::AppState; +/// Top-level Parameters body parameter names recognised by the operation. +/// Anything outside this list is rejected with 400 per the spec's +/// "reject unsupported parameters" rule. +const ALLOWED_BODY_PARAMS: &[&str] = &[ + "view", + "viewResource", // back-compat single-view form + "_format", + "header", + "patient", + "group", + "_since", + "clientTrackingId", + "source", +]; + /// Query parameters for `$viewdefinition-export`. +/// +/// `deny_unknown_fields` enforces the spec's "reject unsupported parameters +/// with 400 Bad Request" rule on the query string.

Resolution reuses the canonical-or-relative helper shared with $sqlquery-run, lifted into handlers/sof/references.rs. The capability statement's `supportsCanonicalReference: true` is now truthful. - Register embedded `url` and `version` search params for ViewDefinition and Library. Without these, the canonical-resolution code paths in $viewdefinition-run, $viewdefinition-export, and $sqlquery-run all returned zero matches because the FHIR base bundle doesn't cover ViewDefinition (an R5+ SoF resource). - `source` parameter now returns 400 + `not-supported` (was 501), via a new RestError::NotSupported variant — matches the spec's error-code examples for refused parameters. NotImplemented (501) stays for features that aren't wired up yet. - Instance-level `POST /ViewDefinition/{id}/$viewdefinition-run` rejects bodies whose `viewResource`/`viewReference` refers to a different ViewDefinition than the path id. Matching or id-less bodies pass through as no-op overrides. - Wire system-level `POST/GET /$viewdefinition-run` route, matching the pattern already used by $viewdefinition-export and $sqlquery-run. --- crates/persistence/src/search/loader.rs | 37 +++- crates/rest/src/error.rs | 22 ++ crates/rest/src/handlers/sof/mod.rs | 1 + crates/rest/src/handlers/sof/references.rs | 178 +++++++++++++++++ crates/rest/src/handlers/sof/run.rs | 158 +++++++++------ crates/rest/src/handlers/sof/sqlquery.rs | 109 +--------- crates/rest/src/routing/fhir_routes.rs | 11 +- crates/rest/tests/sof_run.rs | 222 ++++++++++++++++++++- 8 files changed, 559 insertions(+), 179 deletions(-) create mode 100644 crates/rest/src/handlers/sof/references.rs diff --git a/crates/persistence/src/search/loader.rs b/crates/persistence/src/search/loader.rs index 3e20b98c5..dc4d3519d 100644 --- a/crates/persistence/src/search/loader.rs +++ b/crates/persistence/src/search/loader.rs @@ -611,6 +611,37 @@ impl SearchParameterLoader { .with_source(SearchParameterSource::Embedded), ); + // SQL-on-FHIR canonical resources: `url` and `version` are not in the + // base FHIR R4/R4B search-parameters bundle for ViewDefinition (which + // first appears in R5+).

Four extractors disagreed on that cardinality, so the strict POST path on sof-server silently dropped all but the last `group` entry, and the HFS REST inline FHIRPath path applied only the first patient/group reference. - Add `helios_sof::split_csv_refs` shared comma-split helper; replace the duplicated `split_refs` in `crates/rest/src/handlers/sof/run.rs`. - `filter_resources_by_patient_and_group` now takes `&[String]` for both refs; patient unions across entries. Group still errors when non-empty (audit item #2 will turn that into 400 not-supported separately). - `ExtractedParameters.patient` / `.group` change from `Option` to `Vec`; `process_parameter` accumulates instead of overwriting, matching the shared permissive extractor in `params.rs`. - sof-server `handlers.rs` builds patient/group Vecs (body precedence, comma-split fallback for the query string) and passes slices to the filter at both call sites (source-bundle and provided-resources). - HFS REST `execute_view_inline` drops `.first()` and passes all refs through. The runner path (`ViewFilters`) was already multi-ref. Tests: - New unit test for `split_csv_refs`. - New `test_extract_multiple_group_parameters_accumulate` proving the strict extractor accumulates every group entry. - New `test_inline_run_applies_all_patient_refs` integration test proving multi-patient refs union through the inline FHIRPath path.

The fix drives the scan off the FHIR spec's `CompartmentDefinition-patient.json` (already code-generated as `get_compartment_params`) plus the search- parameter registry's FHIRPath expressions. Spec-data refactor (prerequisite — no circular dep): - Move `SearchParameterRegistry`, `SearchParameterDefinition`, `SearchParameterLoader`, `SearchParameterStatus`/`Source`, `SearchParamType`, `LoaderError`/`RegistryError` from helios-persistence to a new helios-fhir::search module. Strip the unused tokio broadcast machinery (no subscribers existed). Adjust `resolve_param_type` to take `&[&str]` so it doesn't need persistence's `SearchValue` type. - Persistence keeps the runtime/index code (`extractor`, `writer`, `reindex`, `converters`) and re-exports the moved types so its public API stays stable. `resolve_param_type` becomes a thin adapter that maps `&[SearchValue]` to `&[&str]` before delegating. Compartment filter: - New `crates/sof/src/compartment.rs`: - `resource_in_patient_compartment` enumerates the spec-defined compartment params for `(Patient, resource_type)`, resolves each to a FHIRPath expression via the registry, evaluates it against the resource JSON, and matches the resulting Reference(s) against the requested patient set. - `resolve_group_members_to_patient_refs` walks Group resources in the inline bundle and pulls their `member.entity` Patient refs. - `default_registry(FhirVersion)` lazy-loads a process-wide registry from `${HFS_DATA_DIR:-./data}/search-parameters-{ver}.json`, falling back to embedded minimal params. - `filter_resources_by_patient_and_group` now takes `FhirVersion` + `&SearchParameterRegistry`. Group filtering unions resolved group- member patient refs into the effective patient set instead of erroring with 501. - Callers (sof-server `handlers.rs`, HFS REST `run.rs::execute_view_inline`) thread the registry through using `default_search_param_registry`. Tests: - 14 helios-fhir search tests (registry, loader, errors). - 4 new compartment.rs tests (AllergyIntolerance via patient ref, Patient identity, out-of-compartment Library, Group→Patient resolution). - 2 updated handlers.rs tests for the new signature. - New REST integration test `test_inline_run_patient_compartment_ allergyintolerance` exercising the FHIRPath-driven path end to end.

Now passes all refs through. +- **sof-server query string** `RunQueryParams.group: Option` now + comma-splits at the consumption site via the shared `split_csv_refs` + helper lifted into `helios_sof`. + +## 2. `group` refusal uses the wrong status code (sof-server) +- **Spec:** servers refusing a parameter should return `400` with + `not-supported`. Recent commit `5abc11efc` set this precedent for + `source` in HFS REST. +- **sof-server** still maps the "group filtering is not yet implemented" + path to `501 not-supported` via `ServerError::NotImplemented`. + Inconsistent with the `source` refusal policy. + +## 3. Patient-compartment filter — **FIXED** +- **Spec:** "Server SHALL NOT return resources from patient compartments + outside provided list." +- **Before:** `crates/sof/src/lib.rs::filter_resources_by_patient_and_group` + hard-coded a tiny allowlist (`Observation | Condition | + MedicationRequest | Procedure | Encounter`) plus a `.patient` + reference for everything else — leaked out-of-compartment resources + for types not in the allowlist and dropped in-compartment resources + for unrecognized types. +- **After:** New `crates/sof/src/compartment.rs` drives the scan off + `helios_fhir::{r4,r4b,r5,r6}::get_compartment_params` (code-generated + from the spec `CompartmentDefinition-patient.json`) and the lifted + `helios_fhir::search::SearchParameterRegistry`. For each resource and + each requested patient ref, it enumerates the spec-defined search + params linking the resource to the Patient compartment, looks up the + FHIRPath expression in the registry, evaluates it, and matches the + resulting Reference against the requested patient set. Group filtering + resolves `member.entity` Patient references and unions them into the + effective patient set (no more 501). +- **Refactor side-effect:** `SearchParameterRegistry` / loader / status + enums moved from `helios-persistence` to `helios-fhir` (foundational) + so `helios-sof` could use them without a circular dep. The persistence + search-extractor/writer/reindex stay in persistence (index-feed + concerns). + +## 4. `patient` query string is not comma-split (sof-server) +- Spec cardinality is `0..1`, so this is technically fine, but it's + asymmetric with HFS REST's `split_csv_refs` handling and with `group` + (which is multi-valued by spec). Worth noting for future-proofing. + +## 5. No OperationOutcome warning when `patient` / `group` targets are absent +- **Spec:** "Server SHOULD return OperationOutcome if requested patients + absent" (same for group). +- Neither impl checks whether the patient/group ref resolves. Both + silently return an empty result set. SHOULD, not SHALL, but it's a + real omission. + +## 6. sof-server has no system-level endpoint +- **Spec endpoints:** + - `[base]/$viewdefinition-run` + - `[base]/CanonicalResource/$viewdefinition-run` + - `[base]/CanonicalResource/[id]/$viewdefinition-run` +- **HFS REST:** all three wired (per `5abc11efc`). +- **sof-server:** only `/ViewDefinition/$viewdefinition-run`. No + `/$viewdefinition-run` system-level alias. Trivial fix in `server.rs`. + +## 7. sof-server doesn't support the instance-level form +- Stateless → no stored ViewDefinitions to invoke by `{id}`. Acceptable + but the CapabilityStatement should flag this; currently it just lists + `viewdefinition-run` without scope context. + +## 8. Parquet MIME type (sof-server) +- **Spec content-negotiation table:** parquet ↔ + `application/octet-stream`. +- **HFS REST:** ✓ `application/octet-stream` + Content-Disposition. +- **sof-server:** returns `application/parquet` (non-standard). Minor + but a spec-conformant client checking the Accept-table won't match. + +## 9. 422 vs 400 on invalid ViewDefinition (sof-server) +- **Spec status codes:** `422 Unprocessable Entity` for "invalid + ViewDefinition or processing failure". +- **HFS REST:** maps `Uncompilable` / `InvalidViewDefinition` → 422 + (correct, via `map_sof_error_to_rest`). +- **sof-server:** `parse_view_definition_for_version`'s error path in + `handlers.rs` maps `SofError::InvalidViewDefinition` → + `ServerError::BadRequest` → **400**. Should be 422. + +## 10. sof-server's hard `_limit` cap (10000) +- **Spec:** `_limit` is `integer`, no upper bound. +- **sof-server `models.rs`** enforces `1..=10000` and returns `400` for + anything higher. Deployment policy, not a spec violation, but a + spec-conformant client gets refused instead of best-effort honoring. + HFS REST has no such cap. + +## 11. CapabilityStatement gaps (sof-server) +- Advertises only `"format": ["json"]` despite serving CSV/NDJSON/Parquet + on `$viewdefinition-run`. Spec recommends documenting supported output + formats. +- Doesn't advertise the SoF `supportsRelativeReference` / + `supportsCanonicalReference` / `supportsAbsoluteReference` capability + block (HFS does after `5abc11efc`). For sof-server these would all be + `false`, but the absence itself is a gap. + +## 12. Operation canonical URL casing +- Both impls publish the URL as + `http://sql-on-fhir.org/OperationDefinition/$viewdefinition-run`. +- Standard FHIR convention puts no `$` in OperationDefinition `url` — + the `$` only appears in the invocation. The published spec + OperationDefinition JSON should be checked; if its `url` is + `…/OperationDefinition/ViewDefinitionRun` (no `$`), our advertised URL + is wrong. If the spec really uses `$`, ignore. + +## 13. `_format` value-set binding not enforced +- **Spec:** `_format` is bound to `OutputFormatCodes` (extensible). +- Both impls accept `csv | json | ndjson | parquet` plus various MIME + aliases via string match. Neither declares the binding nor validates + against the value set. Acceptable for extensible binding; conformance + audit tools may flag the missing declaration. + +## 14. `header` parameter on non-CSV formats (sof-server) +- **Spec:** "Applies only when csv output is requested." No requirement + to reject it on other formats. +- **sof-server** returns **400** when `header` is set with a non-CSV + `_format`. Stricter than the spec; the spec-aligned behavior is to + silently ignore it. + +## 15. HFS REST: `format_stream` re-runs format validation defensively +- `format_stream` calls `parse_content_type` again and `expect`s + success; the upfront validation in `execute_view` is what makes that + safe. +- Not a spec issue — minor code-quality observation. + +## 16. sof-server double-applies `_limit` +- `run_view_definition_with_options` already honors `RunOptions.limit`, + then `apply_result_filtering` in `models.rs` truncates JSON/NDJSON/CSV + output again.

This commit closes out the remaining cleanup: - Drop the stale "group ... not yet supported" doc comment on the $viewdefinition-run handler. Group is honored now. - Remove the dead `SofError::InvalidViewDefinition → ServerError::NotImplemented` arm in sof-server's `filter_resources_by_patient_and_group` wrapper — the underlying filter no longer emits that variant for group. - Replace the leftover "Item #2 is a separate fix" comment in the handler with a description of the new group resolution path. - Add `test_inline_run_group_resolves_member_patients` covering the full inline pipeline: a `group=Group/g1` ref → resolved against an inline Group → its Patient members union into the effective compartment set → only those Patients survive the filter. - Mark item #2 as fixed in the spec-audit doc. The SHOULD-emit-OperationOutcome-when-target-absent gap remains tracked as audit item #5. --- crates/rest/tests/sof_run.rs | 70 +++++++++++++++++++ .../sof/docs/spec-audit-viewdefinition-run.md | 23 ++++-- crates/sof/src/handlers.rs | 18 ++--- 3 files changed, 95 insertions(+), 16 deletions(-) diff --git a/crates/rest/tests/sof_run.rs b/crates/rest/tests/sof_run.rs index 77b076420..33ab43282 100644 --- a/crates/rest/tests/sof_run.rs +++ b/crates/rest/tests/sof_run.rs @@ -371,6 +371,76 @@ mod sof_run_tests { assert_eq!(rows[0]["family"], "Black"); } + /// Inline group filtering: a `group=Group/g1` ref resolves against a + /// `Group` resource in the inline bundle and its `member.entity` + /// Patient references join the effective patient-compartment set. + /// Pre-audit-#3 the filter returned 501 NotImplemented for any + /// non-empty group_refs (audit item #2).

The Docker image ships with `include_data: false` and `cargo test` runs with the per-crate CWD, so in both contexts the filter silently fell back to the embedded minimal parameter set and went no-op on anything with a non-trivial compartment path (e.g. `Appointment.participant.actor`). Bake the join into the helios-fhir crate at code-gen time: - Extend `fhir_gen` (no side-binary): new `generate_compartment_expressions_file` helper joins `compartmentdefinition-*.json` against `search-parameters.json` from the same per-version resources dir and emits `crates/fhir/src/compartment_expressions/{ver}.rs` exposing `get_compartment_param_expressions(compartment, resource_type) -> &'static [(name, fhirpath)]`. Output is deterministic (BTreeMap-ordered) and lives in a small, reviewable file separate from the giant per-version r4.rs/r4b.rs/r5.rs/r6.rs. - New `--compartments-only` CLI flag on `fhir_gen` regenerates JUST these tables without re-running the full per-version generator (which produces a 100k+ line diff). The full generator still emits the tables as part of a normal run. - `helios_sof::compartment::resource_in_patient_compartment` now consults the compiled-in tables directly. The `default_search_param_registry`/`OnceLock`/`HFS_DATA_DIR` lazy-loader added in the previous compartment commit is gone — no runtime data file is read by the SoF compartment path. - `helios_sof::filter_resources_by_patient_and_group` drops its `&SearchParameterRegistry` argument. sof-server's `handlers.rs` and HFS REST's `execute_view_inline` drop the registry plumbing. Tests: - New `patient_compartment_includes_appointment_via_nested_participant_actor` in `helios_sof::compartment::tests` — the exact case the old hardcoded `(subject|patient)` allowlist couldn't reach. - Existing compartment + sof_run integration tests stay green (92 sof lib + 26 REST sof_run); they now exercise the real compiled-in expressions regardless of CWD.

Previously both inline paths silently returned an empty result set when the requested target wasn't in the bundle. - `filter_resources_by_patient_and_group` now returns `PatientGroupFilterOutcome { resources, warnings }`. The warnings field carries one message per absent `patient` / `group` reference (target Patient or Group resource not in the inline bundle). The filter still runs and returns partial results — warnings are advisory. - sof-server `run_view_definition_handler` accumulates warnings from both filter passes (source-bundle branch + provided-resources branch) and attaches them as `Warning:` HTTP headers (RFC 7234 §5.5, warn-code 199) on the response. Works for every output format (CSV/JSON/NDJSON/Parquet) without altering the body. - HFS REST `execute_view_inline` does the same via a new `build_response_with_warnings` helper. - Audit-doc updated to reflect the inline-path fix; the in-DB runner path remains a follow-up (would need a SearchProvider::read probe before streaming). Tests: - `test_inline_run_emits_warning_for_absent_patient_target` in crates/rest/tests/sof_run.rs — confirms the Warning header is populated when a requested Patient isn't in the supplied bundle. - `test_filter_with_unresolvable_group_returns_empty` updated to assert the new warning text is present. --- crates/rest/src/handlers/sof/run.rs | 31 ++++++- crates/rest/tests/sof_run.rs | 51 +++++++++++ .../sof/docs/spec-audit-viewdefinition-run.md | 22 +++-- crates/sof/src/handlers.rs | 67 ++++++++++++--- crates/sof/src/lib.rs | 86 ++++++++++++++++++- 5 files changed, 232 insertions(+), 25 deletions(-) diff --git a/crates/rest/src/handlers/sof/run.rs b/crates/rest/src/handlers/sof/run.rs index 2c1105edb..6480ac064 100644 --- a/crates/rest/src/handlers/sof/run.rs +++ b/crates/rest/src/handlers/sof/run.rs @@ -487,14 +487,19 @@ where split_csv_refs(params.group.as_deref()) }; + // Track absent-target warnings (audit item #5) to surface as `Warning:` + // HTTP headers on the response. + let mut filter_warnings: Vec = Vec::new(); if !patient_refs.is_empty() || !group_refs.is_empty() { - resources = filter_resources_by_patient_and_group( + let outcome = filter_resources_by_patient_and_group( resources, &patient_refs, &group_refs, fhir_version, ) .map_err(map_sof_lib_error_to_rest)?; + resources = outcome.resources; + filter_warnings.extend(outcome.warnings); } let since = params.since.as_deref().and_then(|s| s.parse().ok()); @@ -529,12 +534,13 @@ where let (ct_header, response_format) = content_type_headers(content_type); - Ok(build_response( + Ok(build_response_with_warnings( StatusCode::OK, ct_header, body, "in-process", response_format, + &filter_warnings, )) } @@ -720,6 +726,21 @@ fn build_response( body: Vec, runner_label: &str, format: &str, +) -> Response { + build_response_with_warnings(status, content_type, body, runner_label, format, &[]) +} + +/// Like [`build_response`] but appends one `Warning:` header per +/// absent-target message (RFC 7234 §5.5, warn-code 199).

The in-DB runner path (HFS storage-backed SoF runner, SQLite + Postgres) still used a hand-rolled `WHERE (subject.reference=? OR patient.reference=?)` JSON-path clause, so nested compartment links like `Appointment.participant.actor` were unreachable. This commit closes that gap on both runners. Approach: the search_index table already has pre-evaluated SearchParameter values populated at resource-write time. For compartment filtering, look up the search-param names that link the resource type to the compartment via `helios_fhir::compartment_params(version, "Patient", resource_type)` and emit an `EXISTS (SELECT 1 FROM search_index ...)` clause against those names — no FHIRPath evaluation at query time, no FHIRPath→SQL compiler. - Add `helios_fhir::compartment_params(version, compartment, resource_type)` as a public version-dispatching helper; HFS REST compartment-search handler now uses it too (removes the local duplicate). - SQLite runner (`crates/persistence/src/sof/sqlite.rs`): replace the hardcoded subject/patient/group JSON-path clause with `compartment_filter_sql` driving an EXISTS against search_index. Patient resources matching their own id stay a special case (compartment owner). Resources not in the compartment at all emit `1=0` (spec: "SHALL NOT return resources from patient compartments outside provided list"). - Postgres runner (`crates/persistence/src/sof/postgres.rs`): same rewrite, $N parameter syntax. - Group filtering on both runners: resolve each `Group/{id}` via an extra DB read, extract `member.entity` Patient references via the shared `helios_sof::resolve_group_members_to_patient_refs` (same helper the inline path uses), fold into the patient filter, then clear the group_refs. Mirrors the inline path's spec-correct semantics rather than the old runner's non-spec literal `Patient.group.reference` match. Tests: - New `test_run_view_definition_appointment_compartment_runner` in crates/rest/tests/sof_run.rs — exercises Appointment.participant.actor through the SQLite runner end-to-end. The exact case the old SQL filter could not handle. - New `test_pg_appointment_compartment_runner` in crates/persistence/tests/sof_pg_runner.rs — same for Postgres (testcontainers). - Update `create_test_server_with_indb` in REST tests to point `data_dir` at the workspace `data/` so the search_index is populated with the real SearchParameter set (the new EXISTS filter depends on it). - Rewrite `test_run_view_definition_group_filter` to seed a real Group with `member.entity = Patient/p-grouped` (the old test seeded a non-spec `Patient.group.reference` field that only worked because of the old hardcoded JSON-path filter). --- crates/fhir/src/lib.rs | 37 +++ crates/persistence/src/sof/postgres.rs | 187 ++++++++++++++-- crates/persistence/src/sof/sqlite.rs | 210 +++++++++++++++--- crates/persistence/tests/sof_pg_runner.rs | 68 ++++++ crates/rest/src/handlers/compartment.rs | 32 +-- crates/rest/tests/sof_run.rs | 115 +++++++++- .../sof/docs/spec-audit-viewdefinition-run.md | 27 ++- 7 files changed, 583 insertions(+), 93 deletions(-) diff --git a/crates/fhir/src/lib.rs b/crates/fhir/src/lib.rs index 8aea9f622..6719478d9 100644 --- a/crates/fhir/src/lib.rs +++ b/crates/fhir/src/lib.rs @@ -1438,6 +1438,43 @@ pub mod search; // Re-export commonly used types from parameters module pub use parameters::{ParameterValueAccessor, VersionIndependentParameters}; +/// Returns the search-parameter NAMES that link `resource_type` to the +/// named compartment (e.g. `"Patient"`, `"Group"`, `"Encounter"`, +/// `"Practitioner"`, `"RelatedPerson"`, `"Device"`), for the specified +/// FHIR version. +/// +/// Thin version-dispatching wrapper around the per-version code-generated +/// `get_compartment_params`.

The persistence From 028a8bed347327ab0556fcbbd73adc1cbe2ee2dc Mon Sep 17 00:00:00 2001 From: Steve Munini Date: Tue, 19 May 2026 14:53:00 +0300 Subject: [PATCH 30/50] fix(sof): wire system-level route and clarify instance scope (audit #6, #7) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit #6 — sof-server's router only published the type-level URL (`/ViewDefinition/$viewdefinition-run`). The SoF v2 spec lists three valid endpoints (system, type, instance); HFS REST already wired all three. This brings sof-server in line: - `POST/GET /$viewdefinition-run` — new system-level alias routes to the same handler as the type-level URL. - `POST/GET /ViewDefinition/$viewdefinition-run` — unchanged. - `POST/GET /ViewDefinition/{id}/$viewdefinition-run` — new route that always returns a clear 400 (see #7). #7 — sof-server is stateless, so the instance-level form (which infers the ViewDefinition from a stored `{id}`) has no meaning. Previously the URL fell through to a routing 404 or returned a misleading 501. Now: - New `instance_level_not_supported` handler returns `400 Bad Request` with an OperationOutcome explaining the stateless limitation and pointing at the supported alternative (inline `viewResource` via POST). - CapabilityStatement's `operation.documentation` enumerates the supported scopes (system + type) and explicitly notes that `viewReference` and instance-level invocation are unavailable. Output formats (`application/json`, `application/x-ndjson`, `text/csv`, `application/octet-stream`) are also listed correctly in `format` (partial closeout of audit item #11). Tests: - `test_capability_statement_structure` (in-handler unit) extended to assert the documentation mentions both scopes + viewResource, and that all four output formats appear in `format`. - `test_instance_level_returns_bad_request` (in-handler unit) confirms the new handler returns `BadRequest` with the stateless explanation and the alternative pointer. - `test_system_level_route_runs_view_definition` (integration) sends a full Parameters body to `POST /$viewdefinition-run` and asserts a 200 NDJSON response with the seeded row. - `test_instance_level_returns_400_with_stateless_explanation` (integration) hits `POST /ViewDefinition/some-id/$viewdefinition-run` and asserts a 400 OperationOutcome with the right text. --- .../sof/docs/spec-audit-viewdefinition-run.md | 43 +++++--- crates/sof/src/handlers.rs | 98 ++++++++++++++++++- crates/sof/src/server.rs | 21 ++++ crates/sof/tests/common/mod.rs | 37 +++++-- crates/sof/tests/server_tests.rs | 78 +++++++++++++++ 5 files changed, 251 insertions(+), 26 deletions(-) diff --git a/crates/sof/docs/spec-audit-viewdefinition-run.md b/crates/sof/docs/spec-audit-viewdefinition-run.md index ba10edcf7..afd893336 100644 --- a/crates/sof/docs/spec-audit-viewdefinition-run.md +++ b/crates/sof/docs/spec-audit-viewdefinition-run.md @@ -115,19 +115,34 @@ closed many gaps; those that remain are listed below. is a follow-up — would need a `SearchProvider::read` round-trip per patient/group ref before the runner starts streaming. -## 6. sof-server has no system-level endpoint +## 6. sof-server system-level endpoint — **FIXED** - **Spec endpoints:** - - `[base]/$viewdefinition-run` - - `[base]/CanonicalResource/$viewdefinition-run` - - `[base]/CanonicalResource/[id]/$viewdefinition-run` -- **HFS REST:** all three wired (per `5abc11efc`). -- **sof-server:** only `/ViewDefinition/$viewdefinition-run`.

HFS REST already emits the spec value; this brings sof-server in line. - All three sof-server Parquet response paths (`crates/sof/src/handlers.rs` small-file direct return, `crates/sof/src/handlers.rs` standard processing, and `crates/sof/src/streaming.rs::stream_single_parquet_response` for large streaming) now emit: Content-Type: application/octet-stream Content-Disposition: attachment; filename="output.parquet" Matches the HFS REST byte-for-byte. (The multi-file ZIP wrapper already used `application/zip` and is unchanged.) - `ContentType::from_string` accepts `application/octet-stream` as the spec input value for the `_format` parameter; `application/parquet` is kept as a permissive alias for back-compat with clients that still send the old shape. - Doc-comment headers in handlers.rs and server.rs updated to list the spec MIME types. Test: - `test_parquet_response_uses_octet_stream_content_type` (integration) asserts the response Content-Type is `application/octet-stream`, the Content-Disposition names a `.parquet` file, and the body starts with the PAR1 magic. --- .../sof/docs/spec-audit-viewdefinition-run.md | 18 +++-- crates/sof/src/handlers.rs | 50 +++++++++++--- crates/sof/src/lib.rs | 8 ++- crates/sof/src/server.rs | 2 +- crates/sof/src/streaming.rs | 10 ++- crates/sof/tests/common/mod.rs | 34 ++++++--- crates/sof/tests/server_tests.rs | 69 +++++++++++++++++++ 7 files changed, 162 insertions(+), 29 deletions(-) diff --git a/crates/sof/docs/spec-audit-viewdefinition-run.md b/crates/sof/docs/spec-audit-viewdefinition-run.md index afd893336..50e86ab2c 100644 --- a/crates/sof/docs/spec-audit-viewdefinition-run.md +++ b/crates/sof/docs/spec-audit-viewdefinition-run.md @@ -144,12 +144,20 @@ closed many gaps; those that remain are listed below. supported scopes (system + type) and explicitly notes that `viewReference` and instance-level invocation are unavailable. -## 8.

Three behavioral fixes plus a parameter cleanup, and the audit log migrates from a single-op draft to a shared spec-inconsistencies doc covering run/export/sqlquery-run. - Failed result URL returns 500 (was 200) per spec status-code table; manifest body still carries `status=failed` + OperationOutcome. - Instance-level endpoint rejects any query/body input parameter with 400 — spec scopes every input parameter to system+type only. - Enforce XOR on `view.viewResource` vs `view.viewReference` (was silently preferring `viewResource` when both were supplied). - Remove `_limit` from $viewdefinition-export — not defined in the spec's input table (unlike $viewdefinition-run, which keeps it). docs/spec-audit-viewdefinition-run.md is superseded by spec-inconsistencies.md, which covers all three SoF operations. --- crates/rest/src/handlers/sof/export.rs | 143 ++++++-- crates/rest/tests/sof_export.rs | 137 +++++++- .../sof/docs/spec-audit-viewdefinition-run.md | 330 ------------------ crates/sof/docs/spec-inconsistencies.md | 148 ++++++++ 4 files changed, 388 insertions(+), 370 deletions(-) delete mode 100644 crates/sof/docs/spec-audit-viewdefinition-run.md create mode 100644 crates/sof/docs/spec-inconsistencies.md diff --git a/crates/rest/src/handlers/sof/export.rs b/crates/rest/src/handlers/sof/export.rs index b2344cf10..5544ca911 100644 --- a/crates/rest/src/handlers/sof/export.rs +++ b/crates/rest/src/handlers/sof/export.rs @@ -78,10 +78,6 @@ pub struct ExportQueryParams { /// Include a CSV header row (default `true`, CSV format only). pub header: Option, - /// Maximum number of output rows. - #[serde(rename = "_limit")] - pub limit: Option, - /// Include only resources modified at or after this instant (RFC 3339). #[serde(rename = "_since")] pub since: Option, @@ -170,20 +166,17 @@ where if let Err(resp) = check_prefer_async(&headers) { return Ok(resp); } - let params = match parse_export_query(raw_query.as_deref()) { - Ok(p) => p, - Err(resp) => return Ok(resp), - }; - let body_value = body.map(|axum::Json(v)| v); - - if let Some(b) = body_value.as_ref() { - if let Some(resp) = validate_unknown_body_params(b) { - return Ok(resp); - } - } - if let Some(resp) = reject_unsupported_source(¶ms, body_value.as_ref()) { + // Spec scopes every input parameter (`view`, `_format`, `header`, + // `patient`, `group`, `_since`, `clientTrackingId`, `source`) to + // "system, type" — none are defined at instance level, where the + // ViewDefinition is identified entirely by the URL path.

Patient-compartment filter — **FIXED** (all three paths) -- **Spec:** "Server SHALL NOT return resources from patient compartments - outside provided list." -- **Before:** `crates/sof/src/lib.rs::filter_resources_by_patient_and_group` - hard-coded a tiny allowlist (`Observation | Condition | - MedicationRequest | Procedure | Encounter`) plus a `.patient` - reference for everything else — leaked out-of-compartment resources - for types not in the allowlist and dropped in-compartment resources - for types not in it (e.g. `Appointment.participant.actor` was - unreachable). -- **After:** `crates/sof/src/compartment.rs` drives the scan off - `helios_fhir::compartment_expressions::{r4,r4b,r5,r6}::get_compartment_param_expressions` - — compiled-in `(search-param-name, FHIRPath-expression)` tables - generated by `cargo run -p helios-fhir-gen -- --all --compartments-only` - (the `--compartments-only` flag was added to `fhir_gen` so the spec-data - join can be refreshed without churning the giant per-version files). - Source: `crates/fhir-gen/resources/{ver}/compartmentdefinition-*.json` - joined against `search-parameters.json`. The filter evaluates each - expression and matches the resulting `Reference`(s) against the - requested patient set. Group filtering resolves `member.entity` - Patient references and unions them in. -- **Zero runtime data-file dependency for the inline path:** the tables - live in the compiled `helios_fhir` binary, so `sof-server` (Docker - image with `include_data: false`) and any test invocation (regardless - of CWD) get spec-correct compartment filtering on the inline path. - The earlier `default_search_param_registry`/`OnceLock`/`HFS_DATA_DIR` - lazy-load was deleted. -- **Runner path (HFS in-DB SOF runner)** — separately fixed for both - SQLite and Postgres backends. The hand-rolled - `(subject|patient)` JSON-path WHERE clause was replaced with an - `EXISTS (SELECT 1 FROM search_index ...)` clause driven by the new - `helios_fhir::compartment_params(version, compartment, resource_type)` - helper. The runner reads pre-evaluated values populated by the - SearchParameter extractor at resource-write time — same source data - the compile-time `get_compartment_param_expressions` tables come - from, just baked into a different shape (DB index vs static table) - for the storage-backed case. Group filtering now does a spec-correct - Group→Patient member resolution (mirroring - `helios_sof::resolve_group_members_to_patient_refs` from the inline - path) before applying the patient compartment filter. -- **Refactor side-effect:** `SearchParameterRegistry` / loader / status - enums moved from `helios-persistence` to `helios-fhir` (foundational) - so `helios-sof` could use them without a circular dep.

Worth noting for future-proofing. - -## 5. Absent-target warning — **FIXED** (inline paths) -- **Spec:** "Server SHOULD return OperationOutcome if requested patients - absent" (same for group). -- **Before:** neither impl checked whether the patient/group ref - resolved. Both silently returned an empty result set. -- **After:** `filter_resources_by_patient_and_group` now returns a - `PatientGroupFilterOutcome { resources, warnings }`. For each - `patient` ref whose `Patient/{id}` isn't in the supplied bundle (and - each `group` ref whose `Group/{id}` isn't there), a warning string is - added. The sof-server handler and HFS REST inline path forward those - to the client as `Warning:` HTTP headers (RFC 7234 §5.5, warn-code - 199 — Miscellaneous warning). The filter still runs and returns - partial results; the warning is advisory, not an error. -- **Scope:** inline paths only (sof-server, HFS REST `execute_view_inline`). - The in-DB runner path on HFS doesn't yet probe storage for the - requested patient/group, so it can't emit the same warning. That gap - is a follow-up — would need a `SearchProvider::read` round-trip per - patient/group ref before the runner starts streaming. - -## 6. sof-server system-level endpoint — **FIXED** -- **Spec endpoints:** - - `[base]/$viewdefinition-run` (system level) - - `[base]/ViewDefinition/$viewdefinition-run` (type level) - - `[base]/ViewDefinition/{id}/$viewdefinition-run` (instance level) -- **Before:** sof-server only routed the type-level URL. -- **After:** `crates/sof/src/server.rs` now wires all three: - - System- and type-level both POST/GET to the same handler — they're - URL aliases for the same operation invocation. - - Instance-level routes to `instance_level_not_supported` (see #7). - - CapabilityStatement documentation describes both supported scopes - so clients can discover the alias without reading code. - -## 7. sof-server instance-level form — **FIXED** (clarified) -- Stateless → no stored ViewDefinitions to invoke by `{id}`. This is - inherent to sof-server's design. -- **Before:** the instance-level URL fell through to a routing 404 or - returned a misleading 501; the CapabilityStatement listed the - operation without scope context. -- **After:** - - Instance-level URLs route to `instance_level_not_supported`, which - returns `400 Bad Request` with an OperationOutcome that explains - the stateless limitation and points at the supported alternative - (`POST /ViewDefinition/$viewdefinition-run` with inline - `viewResource`). - - The CapabilityStatement's `operation.documentation` enumerates the - supported scopes (system + type) and explicitly notes that - `viewReference` and instance-level invocation are unavailable. - -## 8. Parquet MIME type — **FIXED** -- **Spec content-negotiation table:** parquet ↔ - `application/octet-stream`. -- **Before:** sof-server returned `application/parquet` (non-standard) - on all three Parquet response paths (small file, large streaming - single, multi-file ZIP path returns `application/zip` and was - already correct). -- **After:** all sof-server Parquet response paths emit - `Content-Type: application/octet-stream` plus - `Content-Disposition: attachment; filename="…parquet"`. Matches HFS - REST byte-for-byte. `ContentType::from_string` now accepts - `application/octet-stream` as the spec input for the `_format` - parameter; `application/parquet` is kept as a permissive - back-compat alias for clients that still send it. - -## 9. 422 vs 400 on invalid ViewDefinition — **FIXED** -- **Spec status codes:** `422 Unprocessable Entity` for "invalid - ViewDefinition or processing failure". -- **HFS REST:** maps `Uncompilable` / `InvalidViewDefinition` → 422 - (correct, via `map_sof_error_to_rest`). Unchanged. -- **Before:** sof-server's `parse_view_definition_for_version` - special-cased `SofError::InvalidViewDefinition → ServerError::BadRequest` - (400). The other run-time SoF errors flowed through the default - `From` impl → `ProcessingError` → 422 correctly; only the - parse-time path returned 400. -- **After:** the special case was removed; `parse_view_definition_for_version` - now uses the default `From` impl, so an invalid ViewDefinition - surfaces as 422 (matches HFS REST and the spec). All other SoF errors - raised during view execution were already 422. - -## 10. `_limit` cap — **FIXED** (unified across both binaries) -- **Spec:** `_limit` is `integer`, no upper bound. -- **Before:** sof-server's `models.rs` enforced `1..=10000` (returning - 400 for out-of-range values) as a deployment-policy safety cap. HFS - REST had no such cap, so the same `_limit=20000` request was - accepted on one binary and rejected on the other. -- **After:** HFS REST's `execute_view` calls `validate_limit` - (`crates/rest/src/handlers/sof/run.rs`) which enforces the same - `1..=10000` bound and returns the same 400 with a matching error - message. Both binaries now behave identically for `_limit` validation. -- **Spec note:** the cap is still a deployment-policy decision rather - than a spec requirement — the spec leaves `_limit` unbounded. The - cap protects both servers from clients requesting unreasonably - large pages (memory exhaustion, runaway queries). Raising it is a - one-line change in both `validate_limit` (rest) and the - corresponding sof-server validator. - -## 11. CapabilityStatement gaps — **FIXED** -- **`format` field**: closed in the audit #6/#7 fix. - `/metadata` now lists all four MIME types it actually serves - (`application/json`, `application/x-ndjson`, `text/csv`, - `application/octet-stream`). -- **SoF `$sql-on-fhir-capabilities` endpoint**: sof-server now exposes - `GET /$sql-on-fhir-capabilities` returning a `Parameters` resource - that mirrors HFS REST's shape. For a stateless server the truthful - values are: - - `supportsViewDefinitionRun` = `true` - - `supportsViewDefinitionExport` / `supportsSqlQueryRun` / - `supportsInDbRunner` = `false` (no export controller, no - `$sqlquery-run` endpoint, in-process FHIRPath runner only) - - `supportsRelativeReference` / `supportsCanonicalReference` / - `supportsAbsoluteReference` = `false` (no resource store → - `viewReference` is rejected with 501; the capability block reflects - that truthfully so clients don't have to discover it via trial - and error) - - `supportedFormat` = `ndjson`, `json`, `csv`, `parquet` (the four - output formats `$viewdefinition-run` actually emits) - -## 12. Operation canonical URL casing — **VERIFIED CORRECT** (no fix needed) -- The audit's suspicion was that standard FHIR convention puts no `$` - in an OperationDefinition's `url` field (the `$` should only appear - in the invocation path). -- Verified directly against the published SoF v2 spec OperationDefinition - JSON resources on build.fhir.org: - - `OperationDefinition-ViewDefinitionRun.json` → `url = - "http://sql-on-fhir.org/OperationDefinition/$viewdefinition-run"` - - `OperationDefinition-ViewDefinitionExport.json` → `url = - "http://sql-on-fhir.org/OperationDefinition/$viewdefinition-export"` - - `OperationDefinition-SQLQueryRun.json` → `url = - "http://sql-on-fhir.org/OperationDefinition/$sqlquery-run"` -- The spec deliberately uses the `$`-prefixed form (deviates from - standard FHIR convention but is what's published). Our code already - emits these exact strings in both `/metadata` and - `/$sql-on-fhir-capabilities` — no change required. - -## 13. `_format` value-set binding declaration — **FIXED** -- **Spec:** `_format` is bound to - `https://sql-on-fhir.org/ig/ValueSet/OutputFormatCodes` with - `extensible` strength. The bound codes are `csv`, `ndjson`, - `parquet`, `json`, `fhir`. -- **Before:** both impls accepted the spec codes plus a few permissive - MIME aliases, but neither declared the binding in their capability - advertisement. Conformance audit tools couldn't discover it without - dereferencing the OperationDefinition. -- **After:** `/$sql-on-fhir-capabilities` on both binaries now - publishes an explicit `formatBinding` parameter: - ```json - {"name": "formatBinding", "part": [ - {"name": "valueSet", "valueUri": "https://sql-on-fhir.org/ig/ValueSet/OutputFormatCodes"}, - {"name": "strength", "valueCode": "extensible"} - ]} - ``` - Pairs with the existing `supportedFormat` codes which list exactly - the spec codes (sof-server: `ndjson`/`json`/`csv`/`parquet`; - HFS REST adds `fhir` for `$sqlquery-run` output). -- **Validation policy:** spec strength is `extensible`, so we do not - hard-reject unknown codes — we accept what we know (the four - $viewdefinition-run codes plus permissive MIME aliases) and would - return 400 for an unrecognised value. The declaration tells audit - tools the binding exists; the strength tells them it's advisory. - -## 14. `header` parameter on non-CSV formats — **FIXED** -- **Spec:** "Applies only when csv output is requested." No requirement - to reject it on other formats. -- **Before:** sof-server returned 400 when `header` was supplied - alongside a non-CSV `_format` (handlers.rs body-only branch + - common.rs query-string check). Stricter than the spec. -- **After:** the body-only branch now leaves `validated_params.format` - untouched when the negotiated format isn't CSV — the `header` value - is silently ignored. The common.rs stub mirrors the lenient - behavior. `parse_content_type` already handled this correctly - internally (it only applies `header_param` when content-type == - `text/csv`), so the underlying mapping was already spec-aligned; - this commit removes the early-return that was rejecting before the - mapping ran. - -## 15. HFS REST: `format_stream` re-runs format validation — **FIXED** -- **Before:** `execute_view` validated the `_format` string and then - threw away the resulting `ContentType`; downstream `format_stream` - and `execute_view_inline` re-parsed the format string, with - `format_stream` using `.expect("format already validated by - execute_view")` to paper over the duplicate work. A future bug in - one parser-path branch would have panicked instead of producing a - clean error. -- **After:** `execute_view` computes `ContentType` once at validation - time and threads it into both `execute_view_inline` (which no longer - takes `format` + `include_header` separately — the `include_header` - signal is encoded in the `ContentType` enum already via - `CsvWithHeader` vs `Csv`) and `format_stream`. The runner-path - NDJSON-vs-buffered branch matches on `ContentType::NdJson` instead - of string-comparing the format. The `.expect` is gone. -- Not a spec change — pure code-quality cleanup. - -## 16. sof-server double-applied `_limit` — **FIXED** -- **Before:** `run_view_definition_with_options` honored - `RunOptions.limit` at the structured-row level (via - `apply_pagination_to_result`) before serialization, then sof-server's - handler called `apply_result_filtering(output, &validated_params)` - on the serialized bytes — which re-parsed, re-truncated, and - re-serialized. Identical end result, fragile in three ways: - - Inefficient (JSON path re-parsed + re-serialized the entire array). - - CSV-fragile (the line-split truncation assumed no embedded - newlines in quoted fields). - - NDJSON path re-parsed every line as JSON. -- **After:** the `apply_result_filtering` call in the handler is - removed. The whole helper chain (`apply_result_filtering`, - `apply_json_filtering`, `apply_csv_filtering`, - `apply_pagination_to_records`, `apply_pagination_to_lines`) plus - their unit tests are deleted from `models.rs`. End-to-end `_limit` - behavior is still exercised by the existing HTTP-layer tests via - the row-level pass inside `helios_sof::run_view_definition_with_options`. - ---- - -## Severity quick-take - -| # | Item | Severity | Impl | Status | -|---|------|----------|------|--------| -| 1 | Cardinality inconsistency between extractors | High (correctness) | sof-server (+HFS inline) | **fixed** `44bfce41a` | -| 9 | 422 vs 400 on invalid VD | High (status-code spec) | sof-server | **fixed** (this commit) | -| 3 | Patient-compartment fidelity | High (security/leak) | sof-server (+HFS inline) | **fixed** (this commit) | -| 2 | `group` 501 vs 400 | Medium (consistency) | sof-server | **fixed** (this commit; via #3) | -| 6 | System-level route | Medium | sof-server | **fixed** (this commit) | -| 11 | CapabilityStatement formats + refs block | Medium | sof-server | **fixed** (this commit) | -| 5 | Absent-target OperationOutcome | Medium (SHOULD) | both | **fixed** (inline paths; runner-path probe is follow-up) | -| 8 | Parquet MIME | Low | sof-server | **fixed** (this commit) | -| 14 | `header` rejection on non-CSV | Low | sof-server | **fixed** (this commit) | -| 16 | Double-applied `_limit` | Low (perf/CSV-fragile) | sof-server | **fixed** (this commit) | -| 7 | Instance-level not supported | Low (statelessness) | sof-server | **fixed** (clarified; this commit) | -| 10 | `_limit` 10000 cap | Low (policy) | both unified | **fixed** (this commit) | -| 13 | Value-set binding declaration | Low (audit polish) | both | **fixed** (this commit) | -| 12 | Canonical URL casing | Low (verify first) | both | **verified correct** (spec uses `$`; code already matches) | -| 4 | `patient` query comma-split symmetry | Low | sof-server | open | -| 15 | `format_stream` defensive re-validate | Trivial | HFS REST | **fixed** (this commit) | diff --git a/crates/sof/docs/spec-inconsistencies.md b/crates/sof/docs/spec-inconsistencies.md new file mode 100644 index 000000000..d43dcb1ce --- /dev/null +++ b/crates/sof/docs/spec-inconsistencies.md @@ -0,0 +1,148 @@ +# SQL-on-FHIR `$viewdefinition-run`, `$viewdefinition-export`, and `$sqlquery-run` Spec Inconsistencies + +Items where the [SQL-on-FHIR v2 `$viewdefinition-run`](https://build.fhir.org/ig/FHIR/sql-on-fhir-v2/OperationDefinition-ViewDefinitionRun.html), [`$viewdefinition-export`](https://build.fhir.org/ig/FHIR/sql-on-fhir-v2/OperationDefinition-ViewDefinitionExport.html), and [`$sqlquery-run`](https://build.fhir.org/ig/FHIR/sql-on-fhir-v2/OperationDefinition-SQLQueryRun.html) OperationDefinitions are internally inconsistent, ambiguous, or silent on behavior that implementations must nevertheless decide — including places where the sibling operations drift from each other.

The spec is silent on whether the server should: +1. Treat the Bundle as opaque (no entries iterated, ViewDefinition runs against the Bundle itself), or +2. Unwrap `Bundle.entry[*].resource` and apply the ViewDefinition to each entry. + +**Our behavior (asymmetric across binaries):** +- **sof-server** unwraps `Bundle.entry[*].resource` as a convenience — `crates/sof/src/models.rs:332-353`. +- **HFS REST** does not unwrap; the Bundle flows through as a single resource — `crates/rest/src/handlers/sof/run.rs`. + +**Rationale for the asymmetry:** sof-server is the stateless CLI/server path where users commonly pipe FHIR Bundles directly; unwrapping matches their expectation. HFS REST is integrated with persistent storage, where Bundle uploads have explicit batch/transaction semantics elsewhere. + +**Open decision:** Should HFS REST adopt sof-server's unwrap behavior to remove the footgun? Pending direction. If yes, the change point is the `resource` parameter handler in `crates/rest/src/handlers/sof/run.rs`, mirroring `crates/sof/src/models.rs:332-353`. + +**Recommendation:** File a clarification with the SOF working group; in the meantime, make HFS REST match sof-server (Bundle entries flattened). + +--- + +## E — Return type shape diverges between `$viewdefinition-run` and `$sqlquery-run` + +**Spec text:** + +- `$viewdefinition-run` — `return Binary 1..1` for every supported `_format` (`csv`, `json`, `ndjson`, `parquet`). +- `$sqlquery-run` — `return Binary` for the four flat formats, **but** `return Parameters` (with a repeating `row` parameter, one per result row) when `_format=fhir`. + +**Inconsistency:** `$sqlquery-run` introduces a sixth format (`fhir`) that flips the return type to `Parameters`. `$viewdefinition-run` has no equivalent polymorphism — it always returns `Binary` and does not offer a `fhir` format at all. Two sibling operations in the same IG, designed for the same downstream consumers, should not disagree on either the set of supported formats or the return-type contract. + +**Our behavior:** + +- `$viewdefinition-run`: returns raw bytes for `csv`/`json`/`ndjson`/`parquet` (see entry A) — `crates/rest/src/handlers/sof/run.rs`. +- `$sqlquery-run`: returns raw bytes for flat formats and a `Parameters` resource for `_format=fhir` — `crates/rest/src/handlers/sof/sqlquery.rs`. + +**Recommendation:** File a clarification with the SOF working group asking for one of: + +1. Add `_format=fhir` to `$viewdefinition-run` with the same `Parameters` + repeating-`row` return shape, or +2. Drop `_format=fhir` from `$sqlquery-run` and let clients run a follow-up transformation if they need FHIR-typed rows. + +Either way, the supported `_format` set and the return type matrix should be identical across the two ops. + +--- + +## F — Streaming guidance present for `$viewdefinition-run`, absent for `$sqlquery-run` + +**Spec text:** + +- `$viewdefinition-run` says streaming **MAY use chunked transfer encoding for large result sets**, and every worked example shows `Transfer-Encoding: chunked` in the response headers (see entry A). +- `$sqlquery-run` says **nothing** about streaming, chunking, async, or polling. No worked example shows `Transfer-Encoding` at all. + +**Inconsistency:** `$sqlquery-run` is the op more likely to produce unbounded result sets — it executes arbitrary SQL, with no `_limit` or `_since` parameter to constrain output (`$viewdefinition-run` has both). The op that most needs streaming guidance has none; the op that has more natural row caps gets the streaming paragraph. + +**Our behavior:** We stream both ops identically — chunked transfer encoding with raw bytes — because that is the only practical implementation for parquet/NDJSON output regardless of which op served it. + +- `crates/rest/src/handlers/sof/run.rs` +- `crates/rest/src/handlers/sof/sqlquery.rs` + +**Recommendation:** Add a streaming/chunked-transfer paragraph to `$sqlquery-run` that mirrors the one in `$viewdefinition-run`, and explicitly call out NDJSON as the streaming-friendly format on both. Better still, lift the streaming language into a section both OperationDefinitions reference, so the rule is stated once. + +--- + +## G — `Accept: application/octet-stream` semantics undefined on both ops + +**Spec text:** Both operations declare `return Binary` but neither specifies how a client signals "give me the raw payload" vs. "give me a FHIR `Binary` resource envelope with base64-encoded `data`". The OperationDefinition pages do not mention the `Accept` header at all; only the worked examples imply the answer (raw bytes — see entry A). + +**Inconsistency:** The standard FHIR convention for reading a `Binary` resource is: + +- `Accept: application/octet-stream` → server returns the raw payload with `Content-Type` set to the underlying media type (`text/csv`, `application/x-ndjson`, `application/vnd.apache.parquet`, …). +- `Accept: application/fhir+json` (or `+xml`) → server returns a `Binary` resource with `contentType` and base64-encoded `data`. + +Neither SoF op cites this convention, and the per-format implications matter: + +- **Parquet** is the worst case for the envelope form — base64 inflates the payload ~33% and forces clients to decode before they can mmap/scan the file. Anyone asking for parquet wants raw bytes. +- **NDJSON** only streams meaningfully as raw bytes; wrapping it in a base64 `Binary.data` defeats the format. +- **CSV / JSON** can go either way, but clients should be able to ask for raw with `Accept: application/octet-stream`. + +**Our behavior:** Both ops always return raw bytes with the format's native `Content-Type`, regardless of `Accept`. We do not currently honor `Accept: application/fhir+json` by wrapping the payload in a `Binary` envelope. + +- `crates/rest/src/handlers/sof/run.rs` +- `crates/rest/src/handlers/sof/sqlquery.rs` + +**Recommendation:** The spec should state, once, in a shared section both ops reference, that: + +1. When `Accept: application/octet-stream` is present (or absent — i.e. default), the response body is the raw output in the requested `_format` and `Content-Type` reflects the format's native media type. `Transfer-Encoding: chunked` is allowed for streamable formats. +2. When a FHIR media type is requested, the server MAY return a `Binary` resource envelope with the payload base64-encoded — and SHOULD document whether large/streaming formats are supported in this mode at all (parquet and NDJSON realistically are not). + +--- + +## See also + +Other spec ambiguities surfaced during audit but **not** classified as inconsistencies (they are deliberate deployment-policy deviations or out-of-scope conveniences). Tracked separately in the audit log: + +- `_limit` upper bound on `$viewdefinition-run` (we cap at 10000; spec is unbounded). `$viewdefinition-export` rejects `_limit` outright — the spec's input parameter table for the export op does not list it, and the bulk-export contract is unbounded by design. +- `patient` query-string comma-splitting into multiple references (spec cardinality is 0..1 on `$viewdefinition-run`; 0..* on `$viewdefinition-export`). +- `source` URI scheme enumeration (`file://`, `http(s)://`, `s3://`, `gs://`, `azure://` — spec says only "URI or bucket name"). +- R4-only build exposing type+instance routes (spec's R4 OperationDefinition restricts to system-level). +- GET requests carrying `viewResource`/`resource` body (spec text reserves these for POST). +- `$viewdefinition-export` adds `status: in-progress` to its polling Parameters body — the spec's status-polling parameter table lists only `exportId` and `estimatedTimeRemaining`. Additive, no behavioral impact for spec-compliant clients.

Commit 27232ec3b aligned the fn_boundary fixture with FHIR/sql-on-fhir-v2#357, which declares the column type as `dateTime` even when the source FHIRPath expression is a `date` field. That dropped two fixtures (`date lowBoundary`, `date highBoundary` — Patient.birthDate = "1970-06", length 7) from the conformance suite, taking the pass count from 125 to 124 against the floor of 125. FHIRPath `lowBoundary()`/`highBoundary()` preserves source precision: a date input stays date-only, a dateTime input pads to full instant. The compiler's `column_type_hint` can't distinguish the two when the spec author writes `type: dateTime` over a date-typed source. Extend the DateTime emit to dispatch on input length: - length 4 ("YYYY") → date semantics, pad to "YYYY-01-01"/"-12-31" - length 7 ("YYYY-MM") → date semantics, pad to month start/last day - length 10 ("YYYY-MM-DD") → datetime semantics (unchanged) Bumps PASS_FLOOR from 125 to 126 (the suite now passes the previously- failing date boundary cases AND keeps the existing datetime cases green). --- crates/persistence/src/sof/emit.rs | 42 ++++++++++++++++++++++++---- crates/rest/tests/sof_conformance.rs | 2 +- 2 files changed, 38 insertions(+), 6 deletions(-) diff --git a/crates/persistence/src/sof/emit.rs b/crates/persistence/src/sof/emit.rs index 6b4280f02..bf8d54bf7 100644 --- a/crates/persistence/src/sof/emit.rs +++ b/crates/persistence/src/sof/emit.rs @@ -1523,17 +1523,49 @@ fn lower_boundary( ) } BoundaryKind::DateTime => { - // Date-only inputs expand to the earliest (`+14:00`) or latest - // (`-12:00`) UTC offset of the day.

It is independent of `Content-Type`: *any* payload — CSV, JSON, NDJSON, parquet, `application/octet-stream` — can be sent chunked. The choice between `Content-Length` and chunked framing depends solely on whether the server knows the body size before emitting the first byte, never on the `_format`. A separate, genuinely format-sensitive question is **incremental result production** — whether the server can emit output before the full result set is materialized. NDJSON and CSV are trivially row-incremental; a JSON array needs bracket/comma bookkeeping; parquet must finalize its footer (schema, row-group offsets, column statistics) last but can still flush row groups progressively. Even so, once bytes exist they can always be framed chunked — so chunked encoding is never gated on the format.

(Compare entry D, which records a similar sof-server vs. HFS REST asymmetry for Bundle unwrap.) + +**Rationale for the asymmetry:** HFS REST's `$viewdefinition-run` runs against persistent storage and can pull rows lazily from a query stream, so NDJSON — the format that needs no global state — is emitted incrementally. `$sqlquery-run` executes through a SQL engine that materializes the full result set before formatting, so there is nothing to stream incrementally regardless of format. sof-server is the stateless path where the practical pressure is large parquet files, so that is what it streams. + +**Recommendation:** File a clarification with the SOF working group asking it to: + +1. State, once in a section all three ops reference, that `Transfer-Encoding: chunked` MAY be used for the response of **any** `_format` — it is a transport-framing choice, not a format property — and drop any wording that implies it is reserved for "streamable" formats or singles out NDJSON. +2. Separate, explicitly, the two concepts the current text conflates: chunked transfer encoding (HTTP transport framing) vs. incremental result production (a server capability that varies by format and query engine). +3.

Note that `$viewdefinition-export`'s file downloads MAY likewise be chunked, again format-agnostic, while the operation response itself follows the async-bulk model. -**Recommendation:** Add a streaming/chunked-transfer paragraph to `$sqlquery-run` that mirrors the one in `$viewdefinition-run`, and explicitly call out NDJSON as the streaming-friendly format on both. Better still, lift the streaming language into a section both OperationDefinitions reference, so the rule is stated once. +Note that entry A of this document already shows `Transfer-Encoding: chunked` on a `text/csv` response — internal evidence that the NDJSON-specific framing was never right. --- From bb0b2cd6e907e5b7da00c4c7c4b79fc10daceacc Mon Sep 17 00:00:00 2001 From: Steve Munini Date: Thu, 21 May 2026 22:31:54 +0300 Subject: [PATCH 50/50] fix(rest): surface mid-stream errors in $viewdefinition-run instead of silent truncation When the underlying RowStream errors mid-flight, $viewdefinition-run silently truncated its response.
