@netlify/blobs read NODE_ENV while loading, which can trigger Deno 2.9's lazy process global and fail in Netlify's restricted worker. Related: netlify/primitives#712 and netlify/build#7113.

Retry delay is now five seconds in every runtime, with fake timers keeping tests fast. This upstreams vite-hub/vitehub#1095.

📝 Summary

Summary by CodeRabbit

  • Bug Fixes

    • Retry operations now use a consistent five-second delay across environments.
    • Startup no longer reads restricted environment settings when initializing retry behavior.
  • Tests

    • Expanded coverage for retry timing, asynchronous blob operations, and protected environment access.

Walkthrough

The retry delay is now fixed at 5000ms and does not read the runtime environment during import. Retry tests verify import isolation and production timing. Blob write retry tests now use fake timers for API and edge credentials and restore real timers after each test.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to b79d6

This localized change avoids restricted environment access during module import while preserving the retry default and adding regression coverage; no actionable merge-blocking risk remains after normal checks and review.

P1 Badge Avoid touching Deno's lazy process global

In a restricted Deno 2.9.0 worker without the workaround in packages/edge-functions/dev/src/deno/workers/runner.mjs:12-16, even evaluating typeof process accesses Deno's lazy globalThis.process getter, which can call the disallowed Deno.cwd() and throw during import. The new test misses this because it runs under Node and leaves the real process global installed. This therefore does not reliably achieve the stated protected-Deno import fix; use an environment-independent constant rather than inspecting process.

Useful? React with 👍 / 👎.
