### What?
* rename test case
* improve error message and handle edge case for require resolving
* fix test case actually testing externals (webpack was silently
bundling, Turbopack showed error that helped to find the broken test
case)
### Why?
### How?
Closes PACK-2662
### What?
Subscribe to changes of `_error` pages.
### Why?
To make the error overlay disappear when the error is fixed.
I tried skipping related entries by using `continue;` from
5f3b13584c/packages/next/src/server/dev/hot-reloader-turbopack.ts (L675-L684),
but it resulted in it page being rendered in the background while error
overlay does not disappear.
We need to remove the errors from `/_error` page to make the error
overlay disappear, so I tried removing them from the map and it worked.
### How?
Closes PACK-2405
Closes PACK-2644

This ensures we properly set the matched header when applying a
middleware skip optimization so that the client router has enough
context to finish resolving the dynamic route params.
Fixes: https://github.com/vercel/next.js/issues/59561
Closes NEXT-2803
This PR stabilizes an experimental feature that was added in a previous
PR https://github.com/vercel/next.js/pull/50470
It allows the user to set `deploymentId` in `next.config.js`, which is a
unique identifier for a deployment that will be included in each
request's query string or header.
This PR is easier to review with whitespace hidden:
https://github.com/vercel/next.js/pull/63198/files?w=1
Closes NEXT-2789
### What
This is stopgap substitution to webpack's wellknownerrorsplugin. When
webpack compilation hits known errors kind it emits compilation errors
into cli (and dev overlay both) while turbopack currently only emits
into error overlay. PR simply detects if given issue is well known, and
then logs into std.
Probably a long term there should be proper wiring instead; but for now
this allows to make few things work out of the box.
Closes PACK-2727
Enable the `experimental#optimizeServerReact` configuration by default.
Disable the `optimize_use_state` option for the optimization as this may
cause issues in React 19
Closes NEXT-2640
### What
Use SWC to check invalid client hooks of `next/navigation` imports in
server components.
Follow up of #62456
Remove the runtime error APIs for `next/navigation` rsc version.
Add `next/navigation` react-server version alias in turbopack.
This PR also refactored the invalid server layer APIs detection into a
map, where key is import path and value is an array of client APIs.
During the traversing we will get the import source easily, this makes
extending the logic much easier
### Why
Previously we're using the runtime error to check it, but it has to run
first then the error will be thrown. If we error first in build time
with this check it's much faster and we this align on both side between
webpack and turbopack.
No behavior changes in this PR -- this is a refactor to remove the
optional types on `CacheNode` to be more explicit when we aren't copying
over a value and to help with monomorphization. There's still work to be
done to ensure consistent property order, which will come in a separate
PR.

Closes NEXT-2794
### What
When a route handler uses an API that opts it into dynamic rendering
(such as `no-store` on a fetch), and also specifies a `revalidate` time,
the `revalidate` time is ignored and route is treated as fully static.
### Why
`revalidate: 0` and `revalidate: false` have different semantic
meanings: `false` essentially means cache forever, whereas `0` means
it's dynamic. Since `0` is also falsey, the code we have to fallback
with a default `revalidate` value for route handlers is incorrectly not
marking the route as dynamic, and as a result, caching the route without
an expiration time.
### How
This updates the fallback handling for app routes respect a revalidation
value of `0`, so that the page can properly be marked dynamic.
### Test Explanation
This adds 2 new routes handlers: both have a revalidation time specified
& use `no-store` on a fetch, but only one of them specifies `export
const dynamic = 'force-static'`. The one that doesn't specify
`force-static` is correctly omitted from the prerender manifest. The one
that is `force-static` is correctly in the prerender manifest with the
right expiration time. An additional test case was added to verify that
this data refreshes after the specified interval.
Closes NEXT-2764
Addresses some feedback in #62821. This will re-allow implementations
like:
```js
'use server'
export const f = wrapper(async () => {})
```
Where `wrapper` creates a sync function that returns a promise. Although
it will still be silently converted to an async function under the hood.

This ensures we properly catch/handle `generateMetadata` errors during
eager evaluating of nested `generateMetadata` functions in the tree.
Previously if we eager evaluated a child metadata function that threw an
error e.g. `notFound()` and but the parent metadata function took longer
the thrown error would be an unhandled rejection causing the process to
crash depending on the environment.

## What?
Follow-up to #63128
`JSON.stringify(undefined)` ends up with the value `undefined`. However
for Webpack/Turbopack to correctly inject `undefined` into the code it
has to be the string `'undefined'`. This change ensures the
serialization takes into account that case.

Fixes the compile error on all test runs currently:
https://github.com/vercel/next.js/actions/runs/8243077904/job/22543375810?pr=63167#step:27:345
The root cause is that `.d.ts` files automatically include inferred
return types automatically, in this case `tsc` included React class
component `render()` return types in the `.d.ts` for e.g.
error-boundary.tsx / redirect-boundary.tsx. This is a problem because
yesterday that return type was changed:
bf659aefa7 (diff-1d64e275d9755825ba)[…]520436dbd8e1f1fd9fc66a9
and that change also removes one of the previous types that the `.d.ts`
in Next.js automatically included.
This PR changes the `render()` return type to be explicit instead of
inferred, this makes sure that the `.d.ts` file includes only `:
React.ReactNode` instead of the many types of return values allowed.
The reason I went with the explicit type instead of e.g. upgrading
`@types/react` is that upgrading the types would cause existing
applications that use older versions of `@types/react` would break. The
current change ensures it works in both cases.

### What
When triggering an MPA navigation (also commonly referred to as a "hard
navigation"), and then restoring the previous page via the browser's
bfcache, subsequent requests to the same link wouldn't navigate until
reloading the page or performing a different navigation.
### Why
MPA navigations in app router are handled in a fairly unconventional
way: the router state is updated with an indication that an external URL
was clicked, and once the router sees the pending navigation, it kicks
off a `location.replace` or `location.push` with the specified URL **in
render**. The router then suspends indefinitely to prevent committing
the render. However, the router will only make the `replace`/`push`
request if there's not already a pending navigation to that same URL.
The pending check is needed to avoid continuously calling
`push`/`replace` when unrelated router state changes occur (for example,
if I hover over a link and trigger a prefetch action and the router
re-renders, it shouldn't make another `location.push` call to the same
URL that's pending)
However, the source of the bug is that the variable that holds this
pending state is also restored by the browser's cache, since it takes a
snapshot prior to exiting the page. This means that when clicking the
browser back button, `pendingMpaPath` would still be set to the URL we
just came from. When clicking the link again, it would see that the
requested URL is the same as the pending URL, and not perform any
history actions.
### How
This clears the pending value when the router is restored from bfcache.

### What?
This PR removes an unnecessary await keyword from the
writeSema.release() call. The release method does not return a promise,
hence awaiting it is not required.
### Why?
Awaiting on writeSema.release() which does not return a promise can lead
to confusion and potentially hinder performance. By removing the await
keyword, the code is simplified and aligns with the intended synchronous
nature of the release method.
### How?
Reviewed the writeSema.release() method implementation to confirm it
does not return a promise.
Removed the await keyword from the writeSema.release() call to ensure
the code correctly reflects the synchronous operation.

### What?
This fixes a special case where rewrites wouldn't work when resuming a
dynamic page.
### Why?
Previously, as routes would direct-match against entries in the cache,
this takes the `x-matched-path` as the source of truth for these
requests if the `x-now-route-matches` header is not present.
## What?
Working on some refactors to fix a bug with `undefined` handling for
Turbopack. This is the first step by making define-env-plugin.ts have
stricter types so that we can easily find which values are set to
`undefined`.

The value `undefined` can be saved to the incremental cache as
`undefined` (`JSON.stringify(undefined)`) with no errors, but when
retrieving it, we attempt to parse it as JSON using
`JSON.parse(undefined)`. This throws an error. We should instead
deserialize `undefined` as `undefined` when retrieving.
