### What
* Remove the change added in #64467, but still kept tests.
* Add more tests for mixed imports (component and function) from shared
component with `optimizePackageImports`
### Why
The fix in #64467 was not correct, as mixing `export *` with `"use
client"` should error if Next.js detect it properly.
When there's mixed exports, that a shared function will become a client
reference if the target file inherits the client boundary.
The original issue #64467 fixed was actually related to tree-shaking,
which is fixed in #64681.
Closes NEXT-3197
### What
- closes#63896
PR implements parsing JSValue for the matcher config if given item is an
object. We had those types already declared in place but somehow parsing
ignores it.
### What
Closes PACK-2978, requires https://github.com/vercel/turbo/pull/8005.
PR extends existing mdxRs config from accepting object as well in
addition to current boolean flag, mainly to allow to specify what kind
of markdown types will be used between gfm and commonmark.
### What
Reported by @MaxLeiter, when you mixing named import and wildcard import
to a client component, and if you clone the module it will missed others
exports except the named ones. This lead to an issue that rendered React
element type is `undefined`.
### Why
We're using a tree-shaking strategy that collects the imported
identifiers from client components on server components side. But in our
code `connection.dependency.ids` can be undefined when you're using
`import *`. So for that case we include all the exports.
In the flight client entry plugin, if we found there's named imports
that collected later, and the module is already being marked as
namespace import `*`, we merge the ids into "*", so the whole module and
all exports are respected.
Now there're few possible cases for a client component import:
During webpack build, in the outout going connections, there're
connection with empty imported ids (`[]`), cannot unable to detect the
imported ids (`['*']`) and detected named imported ids (`['a', 'b',
..]`). First two represnt to include the whole module and all exports,
but we might collect the named imports could come later than the whole
module. So if we found the existing collection already has `['*']` then
we keep using that regardless the collected named imports. This can
avoid the collected named imports cover "exports all" case, where we
will expose less exports for that collection module lead to the
undefined component error.
Closes NEXT-3177
The function we use to generate a string with named parameters to pass
into `path-to-regexp` currently doesn't properly handle non-word
characters (namely, for the purposes of this bugfix, hyphens). As a
result, `pathToRegexp` will convert something like `/foo/:bar-baz` into
`/^\/foo(?:\/([^\/#\?]+?))-baz[\/#\?]?$/i`, effectively only treating
the `:foo` as part of the regex capture group and leaving a dangling
-baz.
This means using an interception route within a dynamic segment (such as
`/foo/[bar-baz]`) would not properly trigger the route interception
Fixes#64766
### What?
I submitted PR #64499 , it got merged, but it contains a mistake.
I'm terribly sorry about this!
By removing the traceparent from the cachekey, we mistakenly removed the
header from the original object.
Causing the actual request to be executed without the traceparent
header.
### Why?
Creating a cachekey should not alter the original object.
### How?
Flip the arguments for Object.assign

### What?
This ensures that the body limit option is enforced on all request
bodies sent to the Node.js runtime, not just the multipart field size
limits.
### Why?
The documentation states that this should limit the body size,
previously it only limited the field size.
### How?
This uses a `Transform` stream from Node.js. [Based on my
benchmarks](https://gist.github.com/wyattjoh/c470d98095da2f95f5920396aba2a206)
using the transform stream added next to no overhead, yet it did
simplify the implementation quite a bit. Assuming this is due to the
already performant stream support within Node.js.
Closes NEXT-3151
This ensures we only track fetch metrics in development mode as that's
the only time we report them currently, this also adds an upper limit on
how many metrics we store per-request as previously this was unbounded,
on top of that this ensures we don't keep tracking fetch metrics after
the request has ended as we only report on request end, and finally this
adds a clean-up to the reference we attach to the request object
containing the fetch metrics once we have used them.
Closes: https://github.com/vercel/next.js/issues/64212
Closes NEXT-3159
When a server action triggers a redirect, we're incorrectly applying a
refresh marker to the segment they were on, rather than the segment they
were being redirected to. As a result, when revalidation occurs (via
`revalidateX` or `router.refresh()`), the top-level segment would be
replaced with data for an incorrect segment.
For example, if triggering a redirect action from `/redirect` to `/`,
the router state tree would save a reference to `/redirect`. The next
time a refresh or revalidate happens, it'd refresh the segment data for
`/redirect` instead of `/`.
Fixes#64728
Closes NEXT-3156
The `@appsignal/nodejs` instrumentation package fails to load in Next.js
14 due to Webpack failing to bundle its Node.js native extension. Adding
it to the server components external packages list fixes this issue.
Part of https://github.com/appsignal/appsignal-nodejs/issues/1014.
When the router cache can't find a cache node for the requested segment,
it performs a request to the server to get the missing data. This
request to the server currently will always include the `next-url`
header, and on soft-navigations, the router will route the request to
the intercepted handler. This lazy fetch is treated as a soft navigation
by the server, and will incorrectly return data for the intercepted
route.
Similar to the handling in `router.refresh`, and the server action
reducer, we should not include the `next-url` header if there's no
interception route currently in the tree, as otherwise we'll be
erroneously triggering the intercepted route.
Fixes#64676
Closes NEXT-3146
Reverts vercel/next.js#64271
This appears to be causing problems rendering error boundaries on SPA
navigations and needs further investigation
Closes NEXT-3150
### Why
If you have a client entry that mixing `default` re-export and `*`
re-export, atm we cannot statically analyze all the exports from this
the boundary, unless we can apply barrel file optimization for every
import which could slow down speed.
```js
// index.js
'use client'
export * from './client'
export { default } from './client'
```
Before that happen we high recommend you don't mixing that and try to
add the client directive to the leaf level client module. We're not able
to determine what the identifiers are imported from the wildcard import
path. This would work if we resolved the actual file but currently we
can't.
### What
When we found the mixing client entry module like that, we treat it as a
CJS client module and include all the bundle in client like before what
we have the client components import optimization.
Ideally we could warn users don't apply the client directive to these
kinda of barrel file, and only apply them to where we needed.

* https://github.com/vercel/turbo/pull/7995 <!-- Benjamin Woodruff - fix(turbopack-node) postcss.config.js path resolution on Windows -->
(plus unrelated turborepo + CI changes)
This PR should not be cherrypicked into the 14-2-1 branch. Instead https://github.com/vercel/next.js/pull/64677 should be merged into that branch, as that PR contains only the one above Windows commit.
## Info
I did not create a GitHub issue, but this PR for fixing the issue. Hope
that's okay.
## The bug
We run a 'normal' custom server described here:
https://nextjs.org/docs/pages/building-your-application/configuring/custom-server
```ts
const next = require('next');
const dev = process.env.NODE_ENV !== 'production';
const port = 3000;
const app = next({ dev, port, quiet: !dev })
const handle = app.getRequestHandler()
// ...
```
The `quiet` settings is missed in some deeper Next.js internal api
calls. For that reason, the setting did not work at all. This works only
in production mode.
## Testing
I tried to implement a test in `/test/production/custom-server` but I
failed to get the `stderr` messages. When someone give me some guidance,
I will add a new test.
Here are some criteria:
- need: custom server with `quiet: true` setting
- need: a next.js page with thrown error. e.g. `export const
getServerSideProps = () => { throw new Error('failed') }`
- need: collect all `stderr` messages
I tested the fix in our project by editing the files in `node_modules`
-- it worked.
## Background
We upgrade our project from next `13.3.4` to `14.2.0` and saw this
regression. I can not tell in which version this bug was added. We run a
Next.js + 'custom server' + Docker setup. Because we have a lot of
traffic, we need to suppress the standard Next.js logging and using our
own logging.

## What?
- Changes webpack output target to `es6` (required for `async function`
output)
- Adds tests for top level await in server components and client
components (App Router)
- Converted the async-modules tests to `test/e2e`
- Has one skipped test that @gnoff is going to look into. This shouldn't
block merging this PR 👍
Adds additional tests for top level `await`.
Since [Next.js
13.4.5](https://github.com/vercel/next.js/releases/tag/v13.4.5) webpack
has top level await support enabled by default.
Similarly Turbopack supports top level await by default as well.
TLDR: You can remove `topLevelAwait: true` from the webpack
configuration.
In writing these tests I found that client components are missing some
kind of handling for top level await (async modules) so I've raised that
to @gnoff who is going to have a look.

Closes NEXT-3126
Fixes https://github.com/vercel/next.js/issues/43382
### Why
For app page rendering on edge, the `AsyncLocalStorage` (ALS) should be
bundled as same instance across layers. We're accessing the ALS in
`next/dynamic` modules during SSR for preloading CSS chunks. There's a
bug that we can't get the ALS store during SSR in edge, I digged into it
and found the root cause is:
We have both import paths:
`module (rsc layer) -> request ALS (shared layer)`
`module (ssr layer) -> request ALS (shared layer)`
We expect the ALS to be the same module since we're using the same layer
but found that they're treated as different modules due to applying
another loader transform on ssr layer. They're resulted in the same
`shared` layer, but with different resource queries. This PR excluded
that transform so now they're identical across layers.
### What
For webpack, we aligned the loaders applying to the async local storage,
so that they're resolved as the same module now.
For turbopack, we leverage module transition, sort of creating a new
`app-shared` layer for these modules, and apply the transition to all
async local storage instances therefore the instances of them are only
bundled once.
To make the turbopack chanegs work, we change how the async local
storage modules defined, separate the instance into a single file and
mark it as "next-shared" layer with import:
```
any module -> async local storage --- use transition, specify "next-shared" layer ---> async local storage instance
```
Closes NEXT-3085
### What
When rendering a parallel slot multiple times in a single layout, in
conjunction with using an error boundary, the following TypeError is
thrown:
> Cannot destructure property 'parallelRouterKey' of 'param' as it is
null
### Why
I'm not 100% sure of the reason, but I believe this is because of how
React attempts to dededupe (more specifically, "detriplficate") objects
that it sees getting passed across the RSC -> client component boundary
(and an error boundary is necessarily a client component). When React
sees the same object twice, it'll create a reference to that object and
then use that reference in future places where it sees the object. My
assumption is that there's a bug somewhere here, as the `LayoutRouter`
component for the subsequent duplicated parallel slots (after the first
one) have no props, hence the TypeError.
### How
Rather than passing the error component as a prop to `LayoutRouter`,
this puts it as part of the `CacheNodeSeedData` data structure. This is
more aligned with other properties anyway (such as `loading` and `rsc`
for each segment), and seems to work around this bug as the
`initialSeedData` prop is only passed from RSC->client once.
EDIT: Confirmed this is also fixed after syncing the latest React, due
to https://github.com/facebook/react/pull/28669Fixes#58485
Closes NEXT-2095
`initialCanonicalUrl` differs from the `canonicalUrl` that gets set on
the client, such as when there's a basePath set.
This hoists the `canonicalUrl` construction up so we can re-use it when
adding refetch markers to the tree.
This also renames `pathname` -> `path` since it also includes search
params. I added a test to confirm no extra erroneous fetches happened in
both cases.
Fixes#64584
Closes NEXT-3130
Since `AppRouterState` is promise-based (so we can `use` the values and
suspend in render), the state itself isn't stable between renders. Each
action corresponds with a new Promise object. When a link is hovered, a
prefetch action is dispatched, even if the prefetch never happens (for
example, if there's already a prefetch entry in the cache, and it
doesn't need to prefetch again). In other words, the prefetch action
will be dispatched but won't necessarily change the state.
This means that these no-op actions that don't actually change the state
values will trigger a re-render. Most of the context providers in
`AppRouter` are memoized with the exception of `LayoutRouter` context.
This PR memoizes those values so that consumers are only notified of
meaningful updates.
Fixes#63159
Closes NEXT-3127
