+1. **Route handlers received plain Request instead of NextRequest** — `req.nextUrl` was undefined, causing 500 errors. Fixed by wrapping in `NextRequest` in app-rsc-entry.ts. (Iteration 5) +2. **Layout params scoping completely broken** — Every layout received ALL route params instead of scoped per-segment params. Root layout got `{param1, param2}` when it should get `{}`. Fixed `__scopeParamsForLayout` across 4 rendering loops + `buildPageElement`. (Iteration 12) + ## Behavioral Differences Found - **RSC redirect encoding**: Next.js returns 200 for RSC requests with redirect() — the redirect is encoded in the RSC stream so the client-side router handles it. Vinext returns 307 HTTP redirect for both document and RSC requests. The @vitejs/plugin-rsc client router handles this, but it's a behavioral difference that could affect client-side navigation patterns. (Found in rsc-redirect test, iteration 6) +## Process Improvements Made + +- **Added cheerio + `fetchDom` helper** — Can now do DOM-level assertions in tests (querySelector, child count, text by ID). Unlocks porting tests that need DOM structure validation, not just string matching. (Iteration 12) +- **Separate fixtures are viable** — `startFixtureServer()` accepts any directory. Create new fixtures when the shared one doesn't work instead of skipping tests. + ## Promising Directories to Port Next +- **`_allow-underscored-root-directory`** — Tests underscore convention. Could create a small dedicated fixture with `_handlers/` at app root. +- **`node-extensions`** — 50 HTTP-only tests! Tests `.mjs`, `.cjs`, `.js` extension handling in routes. Likely needs dedicated fixture. - **Route handler tests**: Very productive for finding API surface gaps. Check more `app-routes-*` dirs. - **Middleware tests**: `app-middleware`, `app-middleware-proxy` — could find middleware + route handler interaction bugs. - **Actions tests**: `actions`, `actions-navigation` — server actions are core and likely have edge cases. - **Dynamic data tests**: `dynamic-data`, `dynamic-requests` — test request-time API access patterns. - **Redirect/rewrite tests**: `rewrites-redirects` has 2 HTTP-level tests among its 8. + +## Directories Re-evaluate (Previously Skipped) + +These were skipped as "needs custom fixture" but we should create fixtures for them: + +- **`not-found-default`** — Needs custom root layout. Has HTTP test for 404 status on `/_not-found`. +- **`app-basepath`** — Needs basePath config. Has 4 HTTP tests. +- **`trailingslash`** — Needs trailingSlash config.

Fixed by wrapping in `NextRequest` in app-rsc-entry.ts. (Iteration 5) -2. **Layout params scoping completely broken** — Every layout received ALL route params instead of scoped per-segment params. Root layout got `{param1, param2}` when it should get `{}`. Fixed `__scopeParamsForLayout` across 4 rendering loops + `buildPageElement`. (Iteration 12) -3. **force-static pages leaked real `searchParams`** — `headers()` and `cookies()` were emptied, but `pageProps.searchParams` still received live query values. Fixed `buildPageElement()` to pass empty searchParams to force-static pages and metadata resolution. (Iteration 18) -4. **Default 404 pages were not wrapped in layouts** — when no explicit `not-found.tsx` existed, vinext returned a bare 404 instead of Next.js's default 404 UI wrapped in the root/ancestor layouts. Fixed `renderHTTPAccessFallbackPage()` to fall back to `next/error` for 404s and preserve layout wrapping. (Iteration 24) -5. **Middleware had no `next/headers` request context** — calling `headers()` inside middleware crashed even though Next.js allows it. Fixed all middleware execution paths (dev connect runner, App Router generated runtime, Pages/prod generated runtime) to run under `runWithHeadersContext(..., phase="middleware")`. Also fixed draft-mode cookies from middleware by reading `getDraftModeCookieHeader()` before the ALS scope unwinds. (Iteration 25) - -## Behavioral Differences Found - -- **RSC redirect encoding**: Next.js returns 200 for RSC requests with redirect() — the redirect is encoded in the RSC stream so the client-side router handles it. Vinext returns 307 HTTP redirect for both document and RSC requests. The @vitejs/plugin-rsc client router handles this, but it's a behavioral difference that could affect client-side navigation patterns. (Found in rsc-redirect test, iteration 6) - -## Process Improvements Made - -- **Added cheerio + `fetchDom` helper** — Can now do DOM-level assertions in tests (querySelector, child count, text by ID). Unlocks porting tests that need DOM structure validation, not just string matching. (Iteration 12) -- **Separate fixtures are viable** — `startFixtureServer()` accepts any directory. Create new fixtures when the shared one doesn't work instead of skipping tests. - -## Promising Directories to Port Next - -- **Redirect/rewrite tests**: `rewrites-redirects` has 2 pure-HTTP tests for exotic URL-scheme redirects. -- **Dynamic request API tests**: `dynamic-requests` may expose more request-scoped rendering bugs like the force-static searchParams issue. -- **Route handler tests**: Very productive for finding API surface gaps. Check more `app-routes-*` dirs. -- **Middleware tests**: `app-middleware`, `app-middleware-proxy` — could find middleware + route handler interaction bugs. -- **Actions tests**: `actions`, `actions-navigation` — server actions are core and likely have edge cases. - -## Directories Re-evaluate (Previously Skipped) - -These were skipped as "needs custom fixture" but we should create fixtures for them: - -- **`not-found-default`** — Needs custom root layout. Has HTTP test for 404 status on `/_not-found`. -- **`trailingslash`** — Needs trailingSlash config. Has 5 HTTP tests. - -## Bugs / follow-ups uncovered but not fixed yet - -- **`app-basepath`: root `/base` 404s in dev** — Vite serves `basePath + "/"`, so `/base` gets a Vite 404 (`did you mean /base/?`) before vinext routing runs. Next.js serves `/base` correctly. Likely needs a pre-Vite normalization from exact `basePath` → `basePath + "/"` in dev. -- **Static metadata file routes are served but not injected into `<head>`** — `/manifest.webmanifest` and `/metadata/opengraph-image` work, but pages don't get `<link rel="manifest">` / `<meta property="og:image">` automatically from file conventions. This likely blocks `app-basepath` metadata tests and is broader than basePath itself. -- **`dynamic-requests` crashes on unreachable dynamic require/import patterns** — `vite-plugin-commonjs` rejects `require(value)` / `import(value)` even when they are in dead code paths that Next.js allows. This affects both pages and route handlers. diff --git a/autoresearch.jsonl b/autoresearch.jsonl deleted file mode 100644 index 777343e71..000000000 --- a/autoresearch.jsonl +++ /dev/null @@ -1,25 +0,0 @@ -{"type":"config","name":"Next.js compat test audit (issue #204)","metricName":"passing_compat_tests","metricUnit":"","bestDirection":"higher"} -{"run":1,"commit":"5fdfb94","metric":21,"metrics":{"test_files":21,"dirs_covered":13,"skipped_tests":2},"status":"crash","description":"Baseline attempt — metric extraction bug: grep grabbed test file count (21) instead of test case count (233).

-## Objective - -Systematically audit the Next.js test suite (`test/e2e/app-dir/`, 379 directories) and port relevant tests to vinext's `tests/nextjs-compat/` directory. Each iteration picks the next unaudited directory from the manifest, examines the Next.js test source, and either ports the tests (increasing coverage) or marks the directory as irrelevant. - -The real value isn't just the test count — it's **discovering and fixing implementation bugs** along the way (like the `proxy-missing-export` silent fail-open bug from issue #203). - -Reference: https://github.com/cloudflare/vinext/issues/204 - -## Metrics - -- **Primary**: `passing_compat_tests` (count, higher is better) — number of passing test cases in `tests/nextjs-compat/` -- **Secondary**: `test_files` (count of test files), `dirs_covered` (directories with equivalent coverage), `skipped_tests` (tests marked skip) - -## How to Run - -`./autoresearch.sh` — runs `pnpm test tests/nextjs-compat/`, parses vitest output, outputs `METRIC name=number` lines. - -## Iteration Protocol - -Each iteration follows this exact sequence: - -1. **Read manifest** — `autoresearch.manifest.json`. Find the next `"unaudited"` entry with lowest priority number (P1 = error/validation first). - -2. **Read the Next.js test** — Use `gh api` or Context7 (`/vercel/next.js`) to read the test file in `test/e2e/app-dir/<dir>/`. Understand what behavior it validates. - -3. **Classify relevance**: - - `"covered"` — relevant and we will port tests - - `"skip"` — not relevant to vinext (Turbopack-specific, Vercel-deploy-specific, build-tool-specific, requires browser-only Playwright, depends on unimplemented features we won't support) - - `"partial"` — some tests are relevant, others aren't - -4. **If skip**: Update manifest status to `"skip"` with a note explaining why. Log as `discard` (metric unchanged). Move to next directory. - -5. **If relevant (covered/partial)**: - a. Create fixture pages in `tests/fixtures/app-basic/app/nextjs-compat/<name>/` - b. Write test file in `tests/nextjs-compat/<name>.test.ts` (follow existing patterns) - c. Run tests — if they fail due to a vinext bug, **fix the bug in vinext source** - d. Run `./autoresearch.sh` → log as `keep` if passing_compat_tests increased - -6. **Update manifest** — set status and add notes about what was found. - -## Files in Scope - -### Test files (create/modify) - -- `tests/nextjs-compat/*.test.ts` — ported compat tests -- `tests/fixtures/app-basic/app/nextjs-compat/*/` — fixture pages for tests - -### Manifest and tracking - -- `autoresearch.manifest.json` — work queue (status: unaudited/covered/skip/partial) -- `tests/nextjs-compat/TRACKING.md` — human-readable tracking document - -### Vinext source (fix bugs found during porting) - -- `packages/vinext/src/shims/*.ts` — Next.js module reimplementations -- `packages/vinext/src/server/dev-server.ts` — Pages Router SSR handler -- `packages/vinext/src/entries/app-rsc-entry.ts` — App Router RSC entry -- `packages/vinext/src/routing/*.ts` — File-system route scanners -- `packages/vinext/src/index.ts` — Main Vite plugin - -## Off Limits - -- `tests/*.test.ts` (non-compat tests) — read-only, don't modify -- `examples/` — don't touch -- `.github/` — don't touch -- Don't delete or modify existing passing tests in `tests/nextjs-compat/` - -## Constraints - -- **Existing tests must not break.** The checks script runs core tests after each iteration. -- **Follow the existing test pattern.** Use `startFixtureServer()`, `fetchHtml()`, same import style. -- **Include source links.** Every ported test must have a comment linking to the original Next.js test file. -- **One directory per iteration.** Keep iterations focused and revertable. -- **Fix bugs in the same iteration.** If porting a test exposes a vinext bug, fix it now — don't defer. -- **When a directory has many tests, port the most valuable subset** (error cases, validation) rather than trying to port everything in one iteration. - -## Priority Order - -1. **P1: Error handling and validation** (26 dirs) — most dangerous when missing -2. **P2: Edge cases for implemented features** (76 dirs) — catch-all, middleware, redirects, rewrites -3. **P3: Core features** (140 dirs) — RSC, routing, metadata, actions, caching -4. **P4: Other** (103 dirs) — less critical - -## Test Pattern Reference - -```typescript -import { describe, it, expect, beforeAll, afterAll } from "vite-plus/test"; -import type { ViteDevServer } from

-_This section is updated as experiments accumulate._ - -### Baseline (iteration 0) - -- 233 passing tests, 2 skipped, 21 test files -- Covers: app-rendering, not-found, global-error, dynamic, app-routes, metadata, navigation, rsc-basic, hooks, app-css, set-cookies, draft-mode, streaming, app-static (14 Next.js test dirs) - -### Iteration 1: app-fetch-deduping-errors (+3 tests) - -- Ported: page renders despite fetch error in generateMetadata and page component -- No bugs found - -### Iteration 2-3: forbidden + unauthorized (+10 tests) - -- Ported: scoped boundary, root escalation, 403/401 status codes -- Vinext already supports forbidden() and unauthorized() correctly - -### Iteration 4: app-catch-all-optional (+3 tests) - -- Ported: optional catch-all routing with/without rest params -- No bugs found - -### Iteration 5: app-simple-routes (+2 tests) — **BUG FOUND + FIXED** - -- **Bug**: Route handlers received plain `Request` instead of `NextRequest`. `req.nextUrl` was undefined, causing 500 errors. -- **Fix**: Wrapped `request` in `NextRequest` before passing to route handlers in `app-rsc-entry.ts` (same pattern already used for middleware). -- This is exactly the kind of bug issue #204 was designed to catch. - -### P1 Triage Summary (26 dirs) - -- All P1 (error/validation) directories audited -- Most are build-tool-specific (file patching + server restart) or Playwright-only -- Key skip reasons: Redbox assertions, next.cliOutput checks, client-side error boundary interactions - -### Iteration 24: not-found-default (+3 tests) — **BUG FOUND + FIXED** - -- Ported HTTP-testable subset with a dedicated fixture: - - unmatched route renders default 404 inside root layout - - `/_not-found` returns 404 - - grouped dynamic route falls back to default 404 inside group layout -- **Bug**: when no explicit `not-found.tsx` existed, vinext returned a bare default 404 instead of wrapping the default 404 UI in root/ancestor layouts like Next.js does. -- **Fix**: `renderHTTPAccessFallbackPage()` now falls back to `next/error` for 404s, preserving the normal layout wrapping path. - -### Iteration 25: app-middleware (+11 tests) — **BUG FOUND + FIXED** - -- Ported an HTTP-testable subset with a dedicated hybrid fixture: - - middleware request-header mutation for `next/headers` pages + Pages API routes - - draft mode cookie from middleware - - `Link` response header preservation - - `unstable_cache` inside middleware - - plain `Location` response header is not treated as a rewrite -- **Bug**: middleware ran without a `next/headers` request context, so `headers()` inside middleware threw even though Next.js allows it. -- **Bug**: middleware `draftMode().enable()` lost its Set-Cookie header because the code read `getDraftModeCookieHeader()` after the ALS scope had already unwound. -- **Fix**: all middleware execution paths now run inside `runWithHeadersContext(..., phase="middleware")`, and draft-mode cookies are captured before the context exits. -- Snapshot expectations in `tests/entry-templates.test.ts` were updated because both generated middleware runtimes changed. - -### Patterns Observed - -- Many Next.js tests use `next.browser()` (Playwright) — not HTTP-testable with our pattern -- Tests using `next.render$` or `next.fetch` are portable -- Build-time validation tests (file patch + restart + CLI check) are a separate category we can't replicate -- Route handler tests are very productive — they often expose API surface gaps diff --git a/autoresearch.sh b/autoresearch.sh deleted file mode
