### What?
There is a race condition in the `pull-build-cache` script. When the
remote cache entry was removed between the dry run and the real run, it
will run the command and caches whatever is in the native folder.
Seems like there are some very old leftover files there which lead to an
broken publish.
This changes the command to fail when there are no files and empties the
folder before running the script. This should lead to pull-build-cache
to failing instead.
Closes PACK-2957
Fixes#64468
### What
Inherit the client boudaries from the found matched target in load
barrel
### Why
The root cause with the barrel transform, we missed the client boundary
directive during the transform.
Since the new version of mui's case looks like this:
Import path
page.js (server module) -> `<module>/index.js` (shared module) ->
`<module/subpath>/index.js` (client module) ->
`<module/subpath/sub-module.js> (client module)
After our transform, we lost the `"use client"` which causes the
mismatch of the transform:
In `rsc` layer: the file pointing to the sub module entry
(`<module/subpath>/index.js`), but without the client boundary.
Fixes#64369
Closes NEXT-3101
Since the router processes events sequentially, we special case
`ACTION_NAVIGATE` events to "discard" a pending server action so that it
can process the navigation with higher priority. We should apply this
same logic to `ACTION_RESTORE` events (e.g. `router.back()`) for the
same reason.
Fixes#64432
Closes NEXT-3098
`fetchCache` is a more fine-grained segment level cache-control
configuration that most people shouldn't have to use. Current semantics
of `dynamic = "force-dynamic"` will still treat the fetch as cacheable
unless explicitly overriding it in the fetch, or setting a segment level
`fetchCache`.
The `dynamic` cache configuration should be seen as a "top-level"
configuration, while more fine-grained controls should inherit logical
defaults from the top-level. Otherwise this forces people to opt-into
the `fetchCache` configuration, or manually override each `fetch` call,
which isn't what you'd expect when forcing a segment to be dynamic.
This will default to not attempting to cache the fetch when
`force-dynamic` is used. As a result, I had to update one of the
`app-static` tests to use `revalidate: 0` rather than `force-dynamic`,
as the revalidate behavior is slightly different in that it won't modify
the revalidation time on a fetch if it's non-zero.
Closes NEXT-2067
The fix is not correct, we already have request ALS wrapping the request
in app-render, shouldn't get another one for edge adapter. This is
actually a bundler bug
Reverts vercel/next.js#64382
Closes NEXT-3097
## Why?
When you do, →
```
const router = useRouter()
console.log('[test] router =', router.query.slug)
```
the value of `router.query.slug` should be undefined in this instance.
(screenshot from current docs)
it should be `slug: undefined`.
This PR improves the server rendering performance a bit, especially for
the App Router. It has mainly 2 changes.
A rough benchmark test with a 300kB Lorem Ipsum page, SSR is about 18%
faster.
### Improve `getServerInsertedHTML`
- Avoid an extra `renderToReadableStream` if we already know the content
will be empty
- Avoid `await stream.allReady` for better parallelism with
`streamToString()`
- Increase the `progressiveChunkSize`
### Improve `createHeadInsertionTransformStream`
- Only do chunk splitting and enqueuing if the inserted string is not
empty
### Improving Documentation
mistake in the docs.
action should not be apply on the button.
only formAction or onClick is allow.

## What?
- Removes the node-file-trace options from being unsupported as they are
passed to node-file-trace in build/index.ts
- Ensures `import next from 'next'` is handled in the same way as
webpack: creating an empty module. Currently it tried to bundle all
Next.js internals which is wrong.

### What
Wrap async local storage for all edge runtime routes in adapter
Basically fixed the case reported in [this
tweet](https://x.com/keegandonley/status/1778538456458854880)
### Why
We're relying on the ALS for dynamic css preloading but we didn't wrap
the ALS for request handlers for edge. So if you have CSS imports in
`next/dynamic` in edge runtime it would break.

This adds a missing test case for a page which accesses dynamic API's
within `generateMetadata`. It also adds a test case to verify that any
of the URL's being tested can succeed based on the components link
components (it relies on finding a link to click in the browser).
Closes NEXT-3004
Manifests in the runtime should be treated as immutable objects to
ensure that side effects aren't created that depend on the mutability of
these shared objects. Instead, mutable references should be used in
places where this is desirable.
This also introduces the new `DeepReadonly` utility type, which when
paired with existing manifest types, will modify every field to be read
only, ensuring that the type system will help catch accidental
modifications to these loaded manifest values as well.
Future work could eliminate these types by modifying the manifest types
themselves to be read only, only allowing code that generated them to be
writable.

### What?
This creates a new `SharedRevalidateTimings` type that is safe to share
amongst different points within the framework for sharing revalidation
timings. This is a precursor to #64313 which freezes loaded manifests.
### Why?
Using the `SharedRevalidateTimings` type, we no-longer have to modify
the in-memory instance of the prerender manifest to share the
revalidation timings for different routes.
Closes NEXT-3083
## Why
Currently, Server Action handlers are just normal routes and they
accepting POST requests. The only way to differentiate a normal request
(page access, API route, etc.) from a Server Action request is to check
that if it's a POST and has a Server Action ID set via headers or body
(e.g. `multipart/form-data`).
Usually, for existing page and API routes the correct handlers (page
renderer, API route handler) will take precedence over Server Action's.
But if the route doesn't exist (e.g. 404) it will still go through
Server Action's handler and result in an error. And we're eagerly
logging out that error because it might be an application failure, like
passing a wrong Action ID.
## How
In this PR we are making sure that the error is only logged if the
Action ID isn't `null`. This means that it's an intentional Server
Action request with a wrong ID. If the ID is `null`, we just handle it
like 404 and log nothing.
Fixes#64214.
Closes NEXT-3071
* Early return if the `this._module` doesn't exist, aligning with the
type
* If the source is changed, we should return the changed source
otherwise the indexes in source map will be wrong unless the modified
code is appended to the source code, but in this loader it's a different
case
Closes NEXT-3075
Like the No.2 point mentioned in #63489, metadata's title and
description should be the last fallback, if you specify `title` or
`description` in `openGraph` but not in `metadata.twitter`, they should
inherit from open graph first.
For `metadata.twitter`'s fallback order should be:
twitter's title/description > opengraph's title/description > metadata's
title/description
Resolves#63489
Closes NEXT-3073
### What
Bump the edge runtime manifest version and add `environments` property
to each route for inlining values for deployment build.
### Why
In edge runtime, extract the preview props into edge functions manifest
that holding the non-deterministic inline values, then the output build
will be more deterministic that helps deployment speed

Closes NEXT-1912
### What?
This adds a script that first gets a list of changed files compared to
our base branch (`canary`) in PRs and identifies related test files by
looking them up from a `related-tests-manifest.json`, then runs them.
### Why?
We would like to be able to run related E2E tests when certain files
change, so we can test deployment stability.
NOTE: We still want to run all E2E tests on PRs, but this script can be
used to also test deployments for hot paths. Since these tests can take
up to [3-4
hours](https://github.com/vercel/next.js/actions/workflows/test_e2e_deploy.yml),
we aim to run a subset of these tests first.
