Generate `/favicon.ico` route when favicon.ico is placed into `app/`.
Still collect favicon metadata image information through
metadata-image-loader but don't emit the file to static dist anymore.
Also collect favicon through metadata routes, and render it as static
routes. Also remove the `hash` we generated before, not needed anymore.
Change metadata static routes rendering process: collect static metadata
assets, read the buffer of the file data and return it in the response.
Closes NEXT-791
This PR adds basic support for default export of an async arrow
function:
```js
export default async (a, b) => { console.log(a, b) }
```
In upcoming PRs I'll refactor named export handling and inlined
declarations.
This PR adds Zod to the precompiled libraries, and use it to create schemas for the router state tree for validation. In other planned features/changes, Zod will also be used to do run-time data validation.
Fixes NEXT-135.

- no related issue exists, happy to open one if desired

- not sure if specific tests are needed? there is an integration test
for environment variables, and Next.js relies a lot on passing
information through environment variables; i'd expect everything to
break if this change broke environment variable handling

### 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`.

Move error overlay recovery tests in `ReactRefreshLogBox.test.ts` to a
new file. This is already done for the app router tests, but this does
it for the old router as well. Makes `ReactRefreshLogBox.test.ts` faster
to run.
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
Add support for cases like:
```js
const foo = async function () {}
export default foo
const bar = async function() {}
export { bar }
```
Also fix a bug where nested async function declarations are mistakenly
counted as actions.
Fixes NEXT-800.
`test/development/acceptance-app/hydration-error.test.ts` has a lot of tests because I ported all the tests in https://github.com/facebook/react/blob/main/packages/react-dom/src/__tests__/ReactDOMHydrationDiff-test.js. Running all those tests takes a lot of time, and to include all the different cases is overkill.
This PR removes most tests but keeps one test case per type of hydration error, and also one using suspense. This makes more sense, it should only test that all the different hydration error messages are picked up.
Similar to #46888, this PR adds support for the case:
```js
async function foo () {}
export default foo
```
...where you export an ident as a default export expression.
Closes NEXT-770
~Should be landed after #46881.~
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/`.
This ensures we leverage the fetch cache when calling
`generateStaticParams` and also ensures paths with
`generateStaticParams` without `dynamicParams = false` don't error when
only partial params are provided.

Add unique identifier `@app@` / `@pages@` / `@root@` for entry key of on
demand entries, so that they'll be unique for each path when the page
key is similar bewteen app and pages like (`"app/page"` and
`"pages/page"` will both end up with `/page`)

Currently the codemod always runs `root.toSource()`, recreating the
source from the AST. But this can sometimes add unexpected semicolons to
files that actually didn't get updated by the codemod. This PR adds a
check to see if the AST has been updated before running
`root.toSource()`, otherwise it just returns the original source.
This PR adds the support for unnamed default export expression support
`export default async function () {}` in a "use server" entry, with
corresponding test.
Also fixed an existing bug that the default exported action's name
should be aligned with the export name, which is `"default"`.
Closes NEXT-769.
Add a timeout to the Google Fonts fetch calls in dev. In case they
aren't fetched in time, the fallback font is used instead.
Currently if font fetching fails due to network errors in dev, the
loader is not cached. Every change on a page that uses a font makes it
retry to refetch the font. But, if the network is slow enough to cause
timeouts, that means that every change would force the user to wait for
the timeout before the page being updated. Because of this, the PR also
enables the loader to be cached on error. The drawback is that you would
have to delete the `.next` folder to retry to get the actual font in
case it got cached after failing.
Closes NEXT-726

## What?
This PR has its main goal to improve the experience of opening/reviewing
a PR.
It improves the PR template, as well as extends PR auto-labeling.
## Why?
There are 2 parts to the PR template:
- Individual contributors: The current template accommodates for the
most common cases individual contributors use to contribute. (I.e.
fixing bugs, updating/adding examples, addressing documentation issues).
The new template keeps this at the top.
- Next.js team: As maintainers, we should try to explain PRs as if
someone with less context would review them. This should also help with
backreferencing PRs in issues and follow-up PRs and make it easier to
follow changes, understand trade-offs better at the time, and help new
team members catch up over time, etc.
## How?
The template is written in a comment instead of Markdown, so when the PR
is opened, most of the template is hidden to make it less verbose.
The checkboxes we've had before are not shown, but we already auto-label
PRs based on the path of the files that have been touched, so the
checkboxes showed redundant information.

This updates to no longer skip caching POST or authed requests with the
fetch cache and instead we bail when `cookies()` or `headers()` is used
prior which is a better heuristic to signal user specific data would be
related to the fetch request.
