From 3252ef6efaefe29f0d4f132528e7d04e6f8138cb Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ralph=20K=C3=BCpper?= Date: Tue, 19 May 2026 07:30:02 +0200 Subject: [PATCH] =?UTF-8?q?fix(perry-jsruntime):=20#1022=20=E2=80=94=20v8?= =?UTF-8?q?=20proxies=20for=20sqlite=20Database/Statement?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Drizzle's BetterSQLiteSession runs in the V8 fallback path and reads `this.client.prepare(query.sql)` / `stmt.run(...)` / `stmt.all(...)` in session.js. When the perry-side `sqlite` handle (a small integer registered by `js_sqlite_open`) crossed the native→V8 boundary it fell through to `materialize_web_fetch_handle`, didn't match Request/Response/Headers/Blob, and returned `v8::null` — drizzle then threw `Cannot read properties of null (reading 'prepare')` and the compat-sweep fixture printed `count=undefined`. The bridge now materializes real v8::Object proxies for sqlite Database and Statement handles with method callbacks routing back to `js_sqlite_*` FFI shims through `extern "C"` (so the linker-picked impl — perry-stdlib or perry-ext-better-sqlite3 — always wins). Database exposes `prepare`/`exec`/`pragma`/`close`/`transaction`; Statement exposes `run`/`get`/`all`/`raw`/`iterate`/`pluck`/`columns`. `transaction(fn)` is a stub for this close-out: it returns a callable whose `deferred`/`immediate`/`exclusive` properties resolve to the wrapped fn (so `nativeTx[config.behavior ?? "deferred"](tx)` doesn't crash), but doesn't wire BEGIN/COMMIT lifecycle yet — that needs a v8::Function → perry-closure adapter. drizzle's smoke fixture (insert + select + all) doesn't exercise transactions. Files touched: - crates/perry-jsruntime/src/bridge.rs — sqlite proxy materializer + v8 method trampolines + v8→native arg helpers - crates/perry-ext-better-sqlite3/src/lib.rs — `js_sqlite_is_db_handle` / `js_sqlite_is_stmt_handle` membership probes - crates/perry-stdlib/src/sqlite.rs — matching probes for stdlib's fallback registry (linker picks one of the two impls) - crates/perry-stdlib/src/lib.rs — 0-returning stubs when `database-sqlite` feature is off so bridge externs always link - crates/perry-api-manifest/src/entries.rs — surface pragma/iterate/pluck/columns/transaction (api-docs-drift) - docs/api/perry.d.ts + docs/src/api/reference.md — regenerated - test-files/test_better_sqlite3_v8_bridge.ts — fixture exercising the V8-fallback shape without pulling drizzle into the test surface Verification: `/tmp/perry-compat-sweep/drizzle/entry.ts` now prints `count=1` (was: `count=undefined` + TypeError); byte-identical to `node --experimental-strip-types entry.ts`. Existing `test_better_sqlite3_raw.ts` still passes. --- crates/perry-api-manifest/src/entries.rs | 12 + crates/perry-ext-better-sqlite3/src/lib.rs | 32 ++ crates/perry-jsruntime/src/bridge.rs | 497 ++++++++++++++++++++ crates/perry-stdlib/src/lib.rs | 21 + crates/perry-stdlib/src/sqlite.rs | 37 ++ docs/api/perry.d.ts | 2 +- docs/src/api/reference.md | 7 +- test-files/test_better_sqlite3_v8_bridge.ts | 41 ++ 8 files changed, 647 insertions(+), 2 deletions(-) create mode 100644 test-files/test_better_sqlite3_v8_bridge.ts diff --git a/crates/perry-api-manifest/src/entries.rs b/crates/perry-api-manifest/src/entries.rs index 6b38cd712c..5b615e7097 100644 --- a/crates/perry-api-manifest/src/entries.rs +++ b/crates/perry-api-manifest/src/entries.rs @@ -408,6 +408,18 @@ pub static API_MANIFEST: &[ApiEntry] = &[ // Manifest-consistency catch-up (release-sweep gate): NATIVE_MODULE_TABLE // had a `raw` row that wasn't mirrored here. method("better-sqlite3", "raw", true, None), + // #1022 — surface the rest of the v8-proxy-materialized methods so + // the api-docs drift check stays green. `pragma` / `iterate` / + // `pluck` / `columns` / `transaction` are wired through + // `perry-jsruntime::bridge::materialize_sqlite_*_proxy` for the V8 + // fallback path (drizzle on better-sqlite3); the native-side + // codegen lowering already routes the same names through + // `NATIVE_MODULE_TABLE`. + method("better-sqlite3", "pragma", true, None), + method("better-sqlite3", "iterate", true, None), + method("better-sqlite3", "pluck", true, None), + method("better-sqlite3", "columns", true, None), + method("better-sqlite3", "transaction", true, None), // tursodb (#424). open / exec / execBatch / close / // lastInsertRowid / isAutocommit shipped in v0.5.543; queryAll / // queryOne shipped in v0.5.553 (close the row-as-object gap by diff --git a/crates/perry-ext-better-sqlite3/src/lib.rs b/crates/perry-ext-better-sqlite3/src/lib.rs index 60f443e6ab..f3bc5da226 100644 --- a/crates/perry-ext-better-sqlite3/src/lib.rs +++ b/crates/perry-ext-better-sqlite3/src/lib.rs @@ -536,6 +536,38 @@ pub extern "C" fn js_sqlite_in_transaction(db_handle: Handle) -> i32 { 0 } +/// Returns `1` if `handle` currently resolves to a `SqliteDbHandle` in +/// this crate's perry-ffi handle registry, `0` otherwise.
