test: issue #2026

[AriPerkkio]

• Failing test case for fetch can make worker_threads stuck and process hang #2026

Example of failure on CI: https:/AriPerkkio/undici/actions/runs/4551514748/jobs/8025677893#step:14:12832

Somehow tap is able to kill the process even though workers cannot terminate. I'm not sure how it does that as the reproduction case of #2026 cannot exit main thread even when it calls process.exit().

Replace fetch with request and test case will pass.

const requests = Array(count)
-  .fill(urls.map((url) => fetch(url).then((r) => r.json())))
+  .fill(urls.map((url) => request(url).then((r) => r.body.json())))

I've been trying to reproduce this issue with local node:http server without success. I'm serving the raw data with Content-Encoding: br header but something is still missing as the issue does not appear.

I think figuring that out will get us the fix.
