This adds a test that verifies that the search parameters sent to the
server while Partial Prerendering is enabled is actually sent and can be
used by the page.
Closes NEXT-1890
This fixes some of headers (and adds associated tests) for pages when
PPR is enabled. Namely, the `Cache-Control` headers are now returning
correctly, reflecting the non-cachability of some requests:
- Requests that postpone (dynamic data is streamed after the initial
static shell is streamed)
- Requests for the Dynamic RSC payload
Additionally, the `X-NextJS-Cache` header has been updated for better
support for PPR:
- Requests that postpone no longer return this header as it doesn't
reflect the cache state of the request (because it streams)
- Requests for the Prefetch RSC now returns the correct cache headers
depending on the segment and pre-postpone state
This also enables the other pathnames in the test suites 🙌🏻
Closes NEXT-1840
Fixes two build output logs:
- A page that uses `generateStaticParams` & postpones should be marked as partially prerendered
- Assume pages that contain dynamic segments will postpone when PPR is enabled even though it won't be determined until request time
When `patchFetch` is applied at during `buildAppStaticPaths` ([ref](030021234b/packages/next/src/build/utils.ts (L1253-L1256))), it's done so without any context of the bundled React runtime.
Since `patchFetch` will potentially postpone during static generation with PPR, it needs to be using the correct React version, otherwise `unstable_postpone` won't be available e.g. in the case of a page utilizing `generateStaticParams`.
This moves `patchFetch` into the bundled runtime so that it has the correct version of React when invoked.
Rather than sending a warning, we should fail the build if a postpone
call is caught. We should also fail the build if there are any errors
during static generation similar to the non-ppr case.

when calls to `maybePostpone` throw but there's no postpone state, we want to handle those errors differently so that we can provide clearer messaging around how to prevent them, while still retaining any errors that were re-thrown by the user.
ex:
This PR introduces a build optimization to create a "partial prerender" of the page.
1. During compilation, we create a static shell for the page using your existing Suspense boundaries. Components that can be static will be included in this static shell, leaving holes for the dynamic components.
1. Using `<Suspense />`, we can define fallbacks to be included in the partial prerender, as well as the holes for the dynamic components to stream into.
This means Next.js can initially serve a static loading skeleton, kicking off the dynamic parts in parallel. Then, the dynamic components stream in on demand. Dynamic components can use `cookies()`, `headers()`, `'cache': 'no-store'`, or `unstable_noStore()` to opt-into dynamic rendering.
