From bb18ce6a17cfaa9c57d922d9be8e35de3df96414 Mon Sep 17 00:00:00 2001 From: ScriptedAlchemy Date: Fri, 28 Aug 2026 21:56:16 +0000 Subject: [PATCH 01/15] test(rsc): replace watched sources atomically in the provider fixture An in-place write is truncate-then-append, which a loaded watcher observes as two change events and compiles twice; the duplicate attempt supersedes the generation that ordinal-pinned assertions expect, which is exactly how CI committed generation-3 where the equivalent-revision test pinned generation-2. The fixture's three source mutations now go through one same-directory rename so a change is one event and one compile on any machine. --- .../tests/dev-provider.integration.test.ts | 44 +++++++++++++------ 1 file changed, 30 insertions(+), 14 deletions(-) diff --git a/examples/rsc-agent-runtime/tests/dev-provider.integration.test.ts b/examples/rsc-agent-runtime/tests/dev-provider.integration.test.ts index 21cf69a23..ac971022b 100644 --- a/examples/rsc-agent-runtime/tests/dev-provider.integration.test.ts +++ b/examples/rsc-agent-runtime/tests/dev-provider.integration.test.ts @@ -1,6 +1,6 @@ -import { cp, lstat, mkdir, mkdtemp, readFile, readdir, rm, symlink, writeFile } from 'node:fs/promises'; +import { cp, lstat, mkdir, mkdtemp, readFile, readdir, rename, rm, symlink, writeFile } from 'node:fs/promises'; import { tmpdir } from 'node:os'; -import { join } from 'node:path'; +import { basename, dirname, join } from 'node:path'; import { expect, test } from '@rstest/core'; import type { createRsbuild, StartDevServerResult } from '@rsbuild/core'; @@ -98,25 +98,41 @@ const startContext = (input: Readonly<{ const copyProviderExample = async (): Promise => copyExample(exampleRoot, { linkPackages: true, prefix: 'rsc-agent-runtime-provider-' }); -const changeDefinition = async (projectRoot: string, replacement: string): Promise => { - const path = join(projectRoot, 'src', 'definition.ts'); +/** + * Replaces source atomically through a same-directory rename.

two-core runners The parallelism audit inverted the oversubscription hypothesis: rstest already resolves to one worker on a two-core CI runner, so the flakes come from fixed deadlines tuned on many-core machines applied to tests that are inherently multi-process. The sharpest edge was the MCP session layer stamping a five-second timeout on every request - an rsbuild compile or Chrome startup saturates both CI cores for longer than that, tripping -32001 - so the default rises to thirty seconds, still half the MCP SDK's own default. Fixed browser and per-test budgets across the heavy suites now scale four-fold under CI, which costs nothing on green runs since polling assertions return on success, and plugin-bundle.test.ts moves to the serialized integration pool per that list's own admission rule (it runs real builds and spawns node children). --- examples/rsc-agent-runtime/rsbuild.config.ts | 5 ++++ .../src/dev/mcp-session/mcp-session.ts | 6 ++++- .../tests/mcp-session-service.test.ts | 6 ++--- .../tests/script-playground-service.test.ts | 25 ++++++++++--------- .../agent-bundle/tests/support/time-scale.ts | 8 ++++++ ...parisons-page-client-scope-browser.test.ts | 7 +++--- .../workbench/tests/mcp-app-real.e2e.test.ts | 7 +++--- .../tests/mcp-session-timeout.e2e.test.ts | 3 ++- .../tests/packed-release.e2e.test.ts | 7 +++--- .../tests/support/example-acceptance.ts | 3 ++- rstest.integration-tests.ts | 1 + 11 files changed, 51 insertions(+), 27 deletions(-) create mode 100644 packages/agent-bundle/tests/support/time-scale.ts diff --git a/examples/rsc-agent-runtime/rsbuild.config.ts b/examples/rsc-agent-runtime/rsbuild.config.ts index cffbea86f..d85acca9d 100644 --- a/examples/rsc-agent-runtime/rsbuild.config.ts +++ b/examples/rsc-agent-runtime/rsbuild.config.ts @@ -218,6 +218,11 @@ export const createRscRuntimeRsbuildConfig = ( manifest: 'runtime-assets.json', target: 'node', }, + // Rsbuild 2.2 enabled sync chunk splitting for node targets by + // default.

React's Suspense boundary absorbed the throw on green runs and let it escape as an unhandled rejection under CI timing, which is the 'Cannot find module' flake. Instead of copying alias blocks into a fourth config, the vendored inspector core is now a private workspace package whose exports map serves the .js specifiers from the .ts sources, so every resolver - rsbuild, every rstest config, the browser test harnesses, and plain Node - finds it through node_modules; all five alias declarations are deleted. The runtime contract-compile test also stops racing the worker's post-file unhandled-rejection check: its stub answers every route with the status wrapper, so the deliberately rejecting bootstrap fan-out is now awaited and asserted instead of left dangling. --- .../examples/rsc-agent-runtime/README.md | 250 ++ .../rsc-agent-runtime/agent-bundle.config.ts | 41 +

This example's separate +production RSC/runtime artifacts are built by its explicit Rsbuild production +command (`pnpm --filter @agent-bundle/rsc-agent-runtime-demo build`); its provider +uses a separate long-lived Rsbuild development/HMR session only when an +`agent-bundle dev` project opts into `dev.runtime.provider`. Installing +`agent-bundle` alone does not install or activate this example provider. See +[the optional RSC Runtime topology](../../docs/architecture/rsc-runtime-workbench.md) +for the full ownership boundary. + +The build emits `dist/runtime` (including `dist/runtime/agent-runtime.manifest.json`), self-contained `dist/app` MCP App documents, and two self-contained native plugin artifacts under `dist/plugins`. It runs `package:hosts` automatically; it can also be run directly: + +```bash +pnpm --filter @agent-bundle/rsc-agent-runtime-demo package:hosts +``` + +To exercise one hook manually, give it an explicit state file and native Claude-shaped JSON: + +```bash +AGENT_RUNTIME_STATE_FILE=/tmp/rsc-events.jsonl \ + node examples/rsc-agent-runtime/dist/runtime/hook/index.js --host claude <.apps` compiler. It compiles self-contained HTML and exposes it through the virtual `agent-bundle/mcp-apps` resource lane without React/RSC runtime requirements. Opt into this paired RSC runtime only when hooks or MCP tool results genuinely need RSC Flight and shared runtime behavior. + +## Limits and opt-in boundary + +The demo kernel is append-only JSONL: it is appropriate for a small local example, not concurrent/distributed production storage. The RSC-facing packages are exact pins because their framework-facing surface is not treated as stable here: React `19.2.8`, `react-dom` `19.2.8`, `react-server-dom-rspack` `0.1.0`, Rsbuild `2.2.1`, and `rsbuild-plugin-rsc` `0.1.1`. + +Existing Agent Bundle skills, static MCPs, evaluations, and normal hooks neither require nor activate this runtime. Nothing under `packages/agent-bundle` imports the example or React/RSC runtime packages. + +`PlaygroundService` is the landed, provider-neutral durable whole-plugin +authoring timeline foundation. Runtime Playground history is deliberately +provider-session-scoped and ephemeral in this example; wiring a provider +adapter, authenticated API, timeline UI, durable Runtime export, or evaluation +promotion onto that history is an explicit non-goal of this demo. + +## Sources + +- [Rsbuild React Server Components plugin](https://www.npmjs.com/package/rsbuild-plugin-rsc) +- [MCP Apps patterns

It joins package-manager state outside the closure walk, survives a resync, and the fixture test covers both.
