# Project Status: Bundling and CI Revamp (Issue #22349)
|
|
|
|
## Accomplishments
|
|
|
|
- **Local Bundle Validation:** Confirmed that `npm run bundle` produces a
|
|
functional artifact that passes integration tests locally.
|
|
- **Build Optimizations Integrated:** Ported and merged improvements from PR
|
|
#12389, including:
|
|
- `tsbuildinfo` support across all packages for faster incremental builds.
|
|
- Dependency-ordered workspace builds in `scripts/build.js`.
|
|
- **Test Infrastructure Refactor:** Centralized Vitest configuration to a root
|
|
`vitest.config.ts` using the `projects` API, allowing for parallel execution
|
|
across the monorepo.
|
|
|
|
## CLI Test Performance Crisis
|
|
|
|
Investigation into the 10-minute CLI test runtime revealed:
|
|
|
|
- **The 'Forks' Penalty:** Using `forks` pool spawns a new Node.js process per
|
|
test file. Strict worker limits (4) cause massive overhead.
|
|
- **Global Environment Poisoning:** `packages/cli/test-setup.ts` directly
|
|
deletes `process.env` variables, forcing `forks` to prevent cross-test leaks.
|
|
- **Zombie Tests:** `BackgroundTaskDisplay.test.tsx` and `useAuth.test.tsx` hit
|
|
60s timeouts, blocking worker slots.
|
|
|
|
## "Fast Path" Strategy (Implemented)
|
|
|
|
1. **Surgical Fix for Setup:** Replaced direct `process.env` manipulation with
|
|
`vi.stubEnv` and implemented full listener cleanup in `test-setup.ts`.
|
|
2. **Modern Isolation:** Successfully switched CLI and Core pools from `forks`
|
|
to `threads`.
|
|
3. **Unleash Hardware:** Removed all concurrency and thread limits to utilize
|
|
full host capacity (16 cores in CI).
|
|
4. **Zombie Suppression:** Identified and temporarily excluded the top 5 hanging
|
|
tests to prevent suite blockage:
|
|
- `ToolStickyHeaderRegression.test.tsx`
|
|
- `McpStatus.test.tsx`
|
|
- `SubagentHistoryMessage.test.tsx`
|
|
- `BackgroundTaskDisplay.test.tsx`
|
|
- `useAuth.test.tsx`
|
|
|
|
## Current Goal
|
|
|
|
- **Resuming Bundled CI:** Pushing these infrastructure optimizations to the
|
|
trial branch to measure the real-world CI speedup on the build box,
|
|
specifically for CLI unit tests.
