Ports cloudflare-workers to span streaming and keeps the static trace lifecycle covered, via two renames:

  • cloudflare-workerscloudflare-workers-static: verbatim, stays on traceLifecycle: 'static' with the transaction-based specs. Only the app name changes (package.json name, proxyServerName in start-event-proxy.mjs, the proxy name in every waitFor* call in tests/, and the wrangler worker name).
  • cloudflare-workers-streamingcloudflare-workers: same name changes, plus the explicit traceLifecycle: 'stream' pin is dropped so the app exercises the default lifecycle. Its basic-request test now also pins the segment name: the root path / is a route source, so the span keeps the full GET / name under streaming.

Renaming instead of copying keeps both apps' history followable and keeps the diff down to the name changes. Because the path cloudflare-workers exists before and after, git pairs the rename as -streaming → -static and shows cloudflare-workers as modified; the file contents follow the two moves above.

Side effect of the rename: cloudflare-workers inherits the -streaming app's active memory test (memory.test.ts, already running in CI for that app); the two skipped memory tests stay with cloudflare-workers-static.

PR description says the streaming e2e test app is becoming the default but it seems like we're converting and renaming the streaming e2e test to static. Is this intentional?

The GitHub diffing seems to be a little off. In the renames you see that it's also changing it to static. The cloudflare-workers-static looks so wild, as there is now a new -static folder, while the cloudflare-workers test and everything around already existed but only had to change to the streaming tests

ahh thanks for explaining! yeah I think the diff just threw me off. makes sense 👍

…c copy

Renames cloudflare-workers to cloudflare-workers-static, which stays on
traceLifecycle: 'static' with the transaction-based specs, so the static
trace lifecycle keeps E2E coverage. cloudflare-workers-streaming becomes
the new cloudflare-workers and drops its explicit 'stream' pin, so the app
exercises the default lifecycle.
