From a079c2e3de88698a39a75e2c6d64bd8d698dce14 Mon Sep 17 00:00:00 2001 From: anandgupta42 Date: Wed, 18 Mar 2026 08:16:31 -0700 Subject: [PATCH 1/7] =?UTF-8?q?fix:=20dbt=20tool=20regression=20=E2=80=94?= =?UTF-8?q?=20schema=20format=20mismatch,=20silent=20failures,=20wrong=20r?= =?UTF-8?q?esults=20(#261)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Root cause: `schema-resolver.ts` passed flat schema_context (`{"table": {"col": "TYPE"}}`) directly to `Schema.fromJson()`, which expects the Rust `SchemaDefinition` format (`{"tables": {"table": {"columns": [{"name": "col", "type": "TYPE"}]}}}`). The parse silently failed, falling back to an empty schema, causing all schema-dependent tools to produce empty/wrong results. Fixes: - `schema-resolver.ts`: Auto-detect and normalize 3 schema_context variants (flat map, array-of-columns, SchemaDefinition) before calling `Schema.fromJson()` - `sql-analyze.ts`: Check `result.error` instead of `!result.success` to distinguish "issues found" from "analysis failed" - `altimate-core-grade.ts`: Map Rust field names (`overall_grade`, `scores.overall`) instead of `grade`/`score` - `altimate-core-complete.ts`: Use `data.items` (Rust field) with fallback to `data.suggestions` - `altimate-core-schema-diff.ts`: Use `has_breaking_changes` (Rust) and format tagged enum changes correctly - `altimate-core-rewrite.ts`: Use `data.suggestions` (Rust) with fallback to `data.rewrites` - `altimate-core-fix.ts`: Map `fixes_applied`/`unfixable_errors` (Rust fields) instead of `changes`/`errors` - `altimate-core-column-lineage.ts`: Show `column_dict` and use `lens_type` (Rust) for transform info - `sql/register.ts`: Populate `can_auto_apply`, `original_fragment`, `rewritten_fragment` in `sql.rewrite` handler Closes #261 Co-Authored-By: Claude Opus 4.6 (1M context) --- .../src/altimate/native/schema-resolver.ts | 74 +++++- .../src/altimate/native/sql/register.ts | 6 +- .../tools/altimate-core-column-lineage.ts | 26 +- .../altimate/tools/altimate-core-complete.ts | 7 +- .../src/altimate/tools/altimate-core-fix.ts | 16 +- .../src/altimate/tools/altimate-core-grade.ts | 22 +- .../altimate/tools/altimate-core-rewrite.ts | 16 +- .../tools/altimate-core-schema-diff.ts | 32 ++- .../src/altimate/tools/sql-analyze.ts | 4 +- .../altimate/altimate-core-native.test.ts | 40 +++ .../test/altimate/schema-resolver.test.ts | 246 ++++++++++++++++++ .../test/altimate/tool-formatters.test.ts | 216 +++++++++++++++ 12 files changed, 670 insertions(+), 35 deletions(-) create mode 100644 packages/opencode/test/altimate/schema-resolver.test.ts create mode 100644 packages/opencode/test/altimate/tool-formatters.test.ts diff --git a/packages/opencode/src/altimate/native/schema-resolver.ts b/packages/opencode/src/altimate/native/schema-resolver.ts index fadc8df0f..e72b1a3f8 100644 --- a/packages/opencode/src/altimate/native/schema-resolver.ts +++ b/packages/opencode/src/altimate/native/schema-resolver.ts @@ -3,10 +3,82 @@ * * Translates the bridge protocol's `schema_path` / `schema_context` parameters * into altimate-core `Schema` objects. + * + * Tools pass `schema_context` in two possible formats: + * + * 1. **Flat format** (used by most tools): + * `{ "table_name": { "col_name": "TYPE", ... } }` + * + * 2. **SchemaDefinition format** (matches Rust struct): + * `{ "tables": { "table_name": { "columns": [{ "name": "col", "type": "TYPE" }] } } }` + * + * This module normalizes both formats into the SchemaDefinition format + * expected by `Schema.fromJson()`. */ import { Schema } from "@altimateai/altimate-core" +/** + * Detect whether a schema_context object is in flat format or SchemaDefinition format. + * + * Flat format: `{ "table_name": { "col_name": "TYPE" } }` + * SchemaDefinition format: has a `tables` key with nested structure. + */ +function isSchemaDefinitionFormat(ctx: Record): boolean { + return "tables" in ctx && typeof ctx.tables === "object" && ctx.tables !== null +} + +/** + * Convert flat schema format to SchemaDefinition format. + * + * Handles three input variants: + * + * 1.

Mar 2026 08:53:46 -0700 Subject: [PATCH 3/7] test: add 168 simulation tests for altimate-core tool coverage Two new test files exercising all 36 altimate-core napi functions through the dispatcher layer: - `issue-261-e2e.test.ts`: 14 tests reproducing all 11 broken tools from #261 plus schema format variant tests - `edge-cases-simulation.test.ts`: 76 tests covering empty inputs, complex SQL patterns (nested subqueries, CTEs, window functions, correlated subqueries), column lineage through transformations, schema diff with large schemas, PII detection, multi-dialect transpilation, DDL roundtrip, equivalence checks, policy enforcement, and migration safety analysis Total: 192 tests, 404 assertions, 0 failures.

Total e2e suite: 180 tests, 539 assertions, 0 failures.
