From e78ed2756380f6a3d2619865b19d5d79a31f63f6 Mon Sep 17 00:00:00 2001 From: Madhavendra Rathore Date: Fri, 15 May 2026 00:48:48 +0000 Subject: [PATCH 1/6] sea-napi-binding: scaffold native/sea/ crate with version() smoke test Creates the napi-rs binding skeleton: Cargo.toml + lib.rs + module stubs for database/connection/statement/result/error/logger. Captures napi-rs tokio Handle via OnceCell in runtime.rs. Single working #[napi] fn version() proves the binding loads + executes end-to-end in Node. Depends on krn-async-public-api branch (path dep on kernel). Round 2 will add open/execute/fetch methods.

From ee7e82e68803041f5b31df32aa61686ff76f6907 Mon Sep 17 00:00:00 2001 From: Madhavendra Rathore Date: Fri, 15 May 2026 09:02:08 +0000 Subject: [PATCH 4/6] sea-napi-binding: relocate Rust source to kernel workspace MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Per D-006 architectural decision (Python team's workspace pattern): all language bindings (PyO3, napi-rs) now live as workspace siblings in the kernel repo at databricks-sql-kernel/{pyo3,napi}/. What this commit removes from the nodejs repo: - native/sea/Cargo.toml (path dep relocated; package now at databricks-sql-kernel/napi/Cargo.toml with path = "..") - native/sea/build.rs - native/sea/src/* (lib, runtime, database, connection, statement, result, error, logger, util — all 9 files) - native/sea/package.json (the @databricks/sea-native-linux-x64-gnu sub-package moves to the kernel workspace too) - native/sea/index.js (regenerated artifact) What stays in nodejs: - native/sea/index.d.ts — TS declarations consumed by lib/sea/ adapter - native/sea/README.md (new) — explains the move; points readers at databricks-sql-kernel/napi/ What's updated: - package.json: `build:native` and `build:native:debug` scripts now delegate to the kernel workspace via $DATABRICKS_SQL_KERNEL_REPO (defaults to ../../databricks-sql-kernel-sea-WT/napi-binding for the local dev worktree layout). Build copies index.node + index.d.ts back into native/sea/ for the loader to find. Why workspace co-location: - Arrow version pinning lockstep — no silent IPC version drift - path = ".." (clean) vs ../../../../databricks-sql-kernel-sea-WT/... - Single CI: cargo build --workspace covers kernel + pyo3 + napi - Kernel API changes that break either binding caught at PR-review time - Future cgo binding for Go SEA slots in as another workspace member This branch (sea-napi-binding) is now a thin consumer of the kernel napi crate. The actual Rust code lives at krn-napi-binding HEAD on the kernel repo (commit debe3d7).

Driver's engines.node stays >=14 — Thrift consumers on older Node continue to work. - H9 + M1 + M2 types: tsconfig adds a `@sea-native` path alias to native/sea/index.d.ts; loader imports the real Connection / Statement / ConnectionOptions / ExecuteOptions / ArrowBatch / ArrowSchema types and re-exports them. Tests use the re-exported types — the inline-shape duplication across three files collapses. - M3 README: rewrite native/sea/README.md to match kernel reality. The napi crate is a standalone Cargo workspace (not a pyo3 sibling); explain the tls-rustls choice that the standalone workspace exists to enable. - M4 drift detection: mark native/sea/index.d.ts as linguist-generated in .gitattributes so GitHub collapses it in diffs and excludes from blame/language stats. - M5 artifacts: gitignore native/sea/index.js, index.node, index.*.node. - M6 + M7 e2e coverage: decode the IPC payload via apache-arrow's tableFromIPC and assert numRows + cell value (not just shape); add drain-past-null idempotence and schema-before-fetch coverage. - L1 build scripts: collapse build:native + build:native:debug into one script taking BUILD_PROFILE (defaults to --release). - L2 / L4 / M8: drop the version() alias and the "Round 2+ will…" comment debt; the loader now actually delivers the value the prior JSDoc was only promising. Verified on this branch: npm run lint clean (0 errors); npm run prettier clean for PR-owned files (3 unrelated pre-existing warnings on PR #378 territory); tsc --project tsconfig.build.json clean; mocha on tests/unit/sea passes (4/4); mocha on tests/e2e/sea passes against a live pecotesting warehouse (2/2, IPC decode confirms SELECT 1 returns 1).
