Cold-start on showcase packages with heavy Python agents (agno in particular)
consistently lands just over the 25s budget, producing 502s on first probe
with latency_ms: 25001 and stage: "timeout". Raise the upstream
AbortSignal.timeout on /api/smoke from 25s to 45s across all 16 showcase
packages that exercise the full agent round-trip, and bump Next.js
maxDuration from 30s to 60s so the route can actually run that long.
Also bumps the create-integration template so new packages inherit the
new budget.
Tail-latency beyond 45s will still alert — which is the intent.
Evidence: agno 502 alerts tonight at 18:40 PDT and 19:42 PDT, both with
latency_ms: 25001, stage: "timeout" on /api/smoke. /api/health already
200 on both probes — pure cold-start boundary issue.
- test-cleanup.ts: `new Error(msg, { cause })` is ES2022; workspace lib is
ES2020 so the two-arg overload is missing. Replaced with an
`errorWithCause()` helper that assigns `.cause` after construction.
Runtime is identical (Node >=16.9); only the TS signature differs.
- test-cleanup.ts: retyped `SAFE_STDIO` as `StdioOptions` (still frozen at
runtime to keep `test-cleanup.test.ts` freeze assertion green) so
spreading `SAFE_EXEC_OPTS` into `execFileSync(..., opts)` no longer trips
the readonly-vs-mutable-array mismatch on `stdio` (fixes the error at
create-integration.test.ts:132).
- create-integration/index.ts: dropped unused `devCmd` local and unused
`args` parameter on `generateDemoPage` (+ call site); both were dead code
introduced during the parallel-isolation refactor.
- validate-pins.parsers.test.ts: annotated all `withTmp((tmp) => ...)`
callbacks as `(tmp: string)` for robustness under LSP module-resolution
glitches. Matches the contract in `validate-pins.shared.ts`.
Tests: 1061/1061 pass (`pnpm nx run @copilotkit/showcase-scripts:test`).
create-integration.test.ts invoked the real generator against
`showcase/packages/` and `.github/workflows/`, then healed the mutations
in afterEach. Under `fileParallelism: true` that collided with
generate-registry.test.ts (concurrent readdirSync of `showcase/packages/`
observed partial state → ENOENT) and with every suite that restored
workflow YAMLs from git (`.git/index.lock` contention).
Teach `create-integration/index.ts` to honor two env overrides —
`CREATE_INTEGRATION_PACKAGES_DIR` and `CREATE_INTEGRATION_WORKFLOWS_DIR`
— that redirect its writes to any directory. Production behavior
unchanged (defaults resolve to the real paths as before).
Rewrite the test to create a per-suite `os.tmpdir()`-backed root, seed
it with copies of the three real workflow YAMLs so the generator's
regex-based edits still match, and point both env vars there. The test
now never mutates a tracked file — no restorer, no git invocation, no
cross-suite shared state. generate-registry can scan real
`showcase/packages/` concurrently without collisions.
The regression-guard test still exercises the same cleanup semantics,
just against the tmpdir-backed baseline map instead of
`workflowRestorer.snapshotMap`.
