## Issue
The `context.getFilename()` gets the absolute path of the files, and the if statement to filter `/src` and `/app` was not working since #46609.
## Expected
Do not show a lint warning if use `beforeInteractive` inside `appDir`.
Fixes#46609#50261
This passes down the route kind information to the incrememntal cache so it no longer needs to test some files existing in order to validate if the file exists or not for a route.
### What?
Note: This is not a breaking change, just removing some unused code.
### Why?
Since #56896 we don't need this, as Node.js 18+ has `fetch` exposed by default.
### How?
Depends on #56896, #56909
We already didn't load `fetch` if `globalThis` had it (ie. Node.js 18+ environments), and since we are dropping support for Node.js 16, these code paths should have no effect on runtime behavior.
Skips additional production-only tests.
Follow-up to #56089.
In this PR I went through all of `test/integration` looking for `nextBuild(` and added the skipping logic.
We have dropped `experimental.appDir` option, to share the insights that can be removed, add a warning `"App router is enabled by default now, <experimental.appDir> option can be safely removed.'" `
There're few places calling `loadConfig` to access nextjs config for different purpose, and every of them will do validation of next config scheme and could log the warnings potentially to cause duplicated warnings. To address that issue this PR limit the places when should the warnings be logged in certain places, mainly the `next` command entry. Refactor the API here to make it more explicit
Previous logging redeisgn also might trigger duplicated compilation, for instance you compiled page A but then editing another component it might still displaying page A is recompiled. Now we always display `"Compiled .."` message when there's a recompilation but avoid the unnecessary ones such as initial edge compilor ready but there's no modules inside. Then when it recompiles or recovers from error nextjs server will tell "Compiled .." instead of the specific page which might be not related.
Also refactors a minor issue: When `silent` option is set to `true`, auto recorrect next config option from `loadConfig` API like `traillingSlash` is not working
Closes NEXT-1610

Optimizes how we handle cache tags for soft tags (auto-added by Next.js)
and normal tags (added manually) and adds differentiating between
`revalidatePath('/blog/first')` and page/layout.
Soft tags are not stored across cache entry and instead auto sent along
when checking cache entries. This allows us to prevent storing
exponential amounts of tags across cache entries while still having the
relationship between them so that single path revalidation can work
properly.

A continuation of #51864 with RedirectType used in an e2e test and some
ts-ignores removed from the codebase. Happy to split it into two PRs but
I left comments in the two consequential files
---------
This replaces the existing recursive directory reading beheviour with a more efficient implementation. Rather than previously doing actual recursion with the function calls to go deeper into each directory, this has been rewritten to instead use a while loop and a stack. This should improve memory usage for projects with very deep directory structures.
The updated design that performs directory scanning on all directories found at each layer, allowing more filesystem calls to be sent to the OS instead of waiting like the previous implementation did.
**Currently the new implementation is about 3x faster.**
### What?
When cloning a `Request` with `NextRequest` the second argument needs to take precedence over the `Headers` set on the original request.
### Why?
Follow-up of #53157
I checked the `Request` spec https://fetch.spec.whatwg.org/#request-class and following the order of execution, `init.headers` should indeed override the headers if the first param was `Request`.
I verified this in the browser too:
```js
const req1 = new Request("http://n", {headers: {"x-header": "foo"}})
const req2 = new Request(req1, {headers: {"x-header-2": "bar"}})
Object.fromEntries(req2.headers) // {x-header-2: "bar"}
```
So we should match `NextRequest` with this behavior.
### How?
Pass the `init` to `super` when cloning the request.
Closes NEXT-1521
Fixes#54094
Partial fix for #54012: do not generate a blur image in the image loader when the image is detected to be animated, rather than returning the *entire* animated image as the blur image.
### What?
This PR makes it easier to use Next.js with IPv6 hostnames such as `::1` and `::`.
### How?
It does so by removing rewrites from `localhost` to `127.0.0.1` introduced in #52492. It also fixes the issue where Next.js tries to fetch something like `http://::1:3000` when `--hostname` is `::1` as it is not a valid URL (browsers' `URL` class throws an error when constructed with such hosts). It also fixes `NextURL` so that it doesn't accept `http://::1:3000` but refuse `http://[::1]:3000`. It also changes `next/src/server/lib/setup-server-worker.ts` so that it uses the server's `address` method to retrieve the host instead of our provided `opts.hostname`, ensuring that no matter what `opts.hostname` is we will always get the correct one.
### Note
I've verified that `next dev`, `next start` and `node .next/standalone/server.js` work with IPv6 hostnames (such as `::` and `::1`), IPv4 hostnames (such as `127.0.0.1`, `0.0.0.0`) and `localhost` - and with any of these hostnames fetching to `localhost` also works. Server Actions and middleware have no problems as well.
This also removes `.next/standalone/server.js`'s logging as we now use `start-server`'s logging to avoid duplicates. `start-server`'s logging has also been updated to report the actual hostname.
The above pictures also demonstrate using Server Actions with Next.js after this PR.

### What?
Allow the following:
```ts
new NextRequest(new Request(...))
```
### Why?
Cloning a request by passing it to the constructor of another `Request` is allowed by the spec: https://developer.mozilla.org/en-US/docs/Web/API/Request/Request#parameters
### How?
If the passed argument is an instance of `Request`, we pass it as-is to `super()`
Fixes#52967
Closes NEXT-1468
### Description
This PR refactors the Image component so that the core logic can be consolidated into a single function.
This allows usage outside of `<Image>`, such as:
1. Working with [`background-image`](https://developer.mozilla.org/en-US/docs/Web/CSS/background-image) or [`image-set`](https://developer.mozilla.org/en-US/docs/Web/CSS/image/image-set)
2. Working with canvas [`context.drawImage()`](https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API/Tutorial/Using_images) or simply `new Image()`
3. Working with [`<picture>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/picture) media queries to implement Art Direction or Light/Dark Mode images
### Example
```tsx
import { unstable_getImgProps as getImgProps } from 'next/image'
export default function Page() {
const common = { alt: 'Hero', width: 800, height: 400 }
const { props: { srcSet: dark } } = getImgProps({ ...common, src: '/dark.png' })
const { props: { srcSet: light, ...rest } } = getImgProps({ ...common, src: '/light.png' })
return (<picture>
<source media="(prefers-color-scheme: dark)" srcSet={dark} />
<source media="(prefers-color-scheme: light)" srcSet={light} />
<img {...rest} />
</picture>)
}
```

## Why?
```
src/app/layout.tsx
```
**eslint[@next/next/no-before-interactive-script-outside-document](https://nextjs.org/docs/messages/no-before-interactive-script-outside-document)**
> `next/script`'s `beforeInteractive` strategy should not be used outside of `pages/_document.js`.
## How?
- Possibility of pathname starts with "/" on OS X and Linux, so added condition to check file path starting with "/"
- e.g. "/src/app" or "/app"
- Added test code
Passed
- `pnpm build && pnpm lint`
- `pnpm jest test/unit/eslint-plugin-next/no-before-interactive-script-outside-document.test.ts`
Extends #46609Fixes#50096
Fixes NEXT-1230
client refs are not correctly extracted as we're using regex to get the exports names from cjs file. The regex was extracting some bad names from the code source, this PR fixes the regex to make sure they extract the correct content
Fixes NEXT-1213
The `pathname` in app-render was actually "page" (e.g. `/blog/[slug]`),
with special url conventions. Instead we should use actual request url
as pathname. Rename previous `pathname` arg to `pagePath` for better
readability
Also improved the url validation
### What
For dynamic routes you might have different sitemap for different params
* Unloack using `sitemap.[ext]` in your app everywhere
* Support `generateSitemaps()` to create multiple sitemaps at the same time
### How
* Change the metadata regex to allow use sitemap in every routes
* Similar approach to `generateImageMetadata`, we make `sitemap.js` under dynamic routes to a catch all routes, and it can have multiple routes
Closes NEXT-1054
### What
`export const runtime = 'experimental-edge'` also work for pages. This
PR add tests for that.
Closes NEXT-426
Follow up for #46631 that to fully remove all related code of the
`experimental.runtime`
### What?
In environments where `FileSystemCache` is used, the cache for static
resources such as image files will be broken.
### Why?
Because `fs.readFile(path, 'utf8')` tries to read a file as a `string`.
### How?
Change to use `fs.readFile(path)` to always read files as binary
(`Buffer`).
In a previous PR (https://github.com/vercel/next.js/pull/46753), the
`originalSource` was saved to be passed along through the build process.
This was done a bit too late in the flow, which made `originalSource`
include some transformations.
Because `originalSource` is used for display purposes, we need it
unmodified. This PR preserves `originalSource`.
This unblocks further optimization opportunities as well as fixes for
systematic problems such as NEXT-227. After this PR, only production
mode of non-app projects will be running on the legacy main process
mode.

### What?
Re-assigning `process.env` substitutes the "magic object" that sets
environment variables at the process level with an ordinary JavaScript
object. This causes environment variables that are set after
`process.env` is re-assigned to not be visible to native add-ons.
See [this Node.js issue][issue] and [this reproduction case][repro] for
details.
[issue]: https://github.com/nodejs/node/issues/46996
[repro]: https://github.com/unflxw/nodejs-process-env-addons-repro
### Why?
In general, paraphrasing the maintainer in the Node.js issue,
re-assigning `process.env` is not a thing you should do. More
specifically, I'm trying to use Next.js' experimental OpenTelemetry
support with AppSignal's Node.js integration, which also uses
OpenTelemetry.
The AppSignal Node.js package sets environment variables in order to
configure a long-running process, which is then launched through a
native add-on. Because of the re-assignment of `process.env` that occurs
early in Next.js' lifecycle process, by the time the AppSignal Node.js
package sets environment variables, it's setting them in an ordinary
JavaScript object that Next.js left in the global `process` object, not
in the magic one created by the Node.js runtime.
This means that these environment variables are not _actually_ being set
for the process at the OS level, and therefore they're also not set for
the native add-on, or for the long-running process it spawns.
### How?
A `replaceProcessEnv` function is implemented that takes an environment
object as an argument, and applies the difference between that
environment object and the current environment to the existing
`process.env` object. This function is used instead of re-assigning
`process.env`.

Support top level static `robots.txt` and `sitemap.xml` as metadata
route in app directory. When those files are placed in top root
directory
Refactored a bit the page files matching logic, to reuse it between dev
server and build
Closes NEXT-267
fixes https://github.com/vercel/next.js/issues/46549
The docs are wrong for now, this limitation is just in `pages/`, you can
use it anywhere in `app/`.
Since `app/` is still not stable we will emit that warning in all files
outside of `app/`.
Currently all helper functions are exported from huge utils files. This
moves the helper functions to their own files, this approach aligns
better with the rest of the codebase.
The unit tests are split up and colocated with the function it tests.
Also added some missing tests.
Plus some overall cleanup, added comments and fixed types.

When you have `app/page.js` and `pages/page.js`, the `pagePath` are the
same, which is `/page`. This will result require cache conflicts. When
you visit the `app/` page first, then the `pages/` page, the 2nd request
will still get the app dir page module, which result in server error.
Solution: use different cache key of pagePathCache for pages/ and app/
