From baa5dfd7b99364347f3d9dea87dd7548df30bb64 Mon Sep 17 00:00:00 2001 From: suryaiyer95 Date: Wed, 25 Mar 2026 17:38:19 -0700 Subject: [PATCH 01/12] fix: patch hardcoded `__dirname` in `dbt-tools` bundle so `altimate-dbt` works in published releases `bun build` replaces `__dirname` with a compile-time constant when bundling `python-bridge` (transitive dep of `@altimateai/dbt-integration`). In CI this bakes `/home/runner/work/...` into the bundle, causing `altimate-dbt build` and all Python-bridge commands to fail with ENOENT on every user's machine. Fix: - Copy `node_python_bridge.py` into `dist/` alongside `index.js` - Post-process the bundle to replace the frozen path with `import.meta.dirname` - Fail the build if the patch pattern isn't found (safety net) - Add CI smoke test to prevent regression Broken since PR #201. Closes #466.

Fix: clear hook in `beforeEach`. - `dbt-first-execution.test.ts`: `mock.module` for DuckDB leaked across files. Fix: spread real module exports + ensure native/index.ts import. - `tracing-adversarial-final.test.ts`: 50ms snapshot waits too tight for CI under load. Fix: increase to 200ms/300ms.
