This was leftover from when we were using yarn but `--force` has different behavior in pnpm (it will install all optionalDependencies regardless of the current environment), which was causing tests to slowdown
### What?
I think the flakiness from the new stream cancel tests is due to a uncaught error thrown from the priming. If it is during the priming, then we need to also explicitly check if we restart the test and reset the `streamable`.
### Why?
Flakey tests suck.
### How?
- Adds a `on('error', reject)` to catch the socket error and associate it with the test
- Explicitly checks for the `?write=` param to see if we're priming or getting results
When verbose logging is enabled and a cache MISS is logged due to either `revalidate: 0`,`cache: no-store` or `cache-control: no-store`, this logs a slightly different message, ie:
```
- GET / 200 in 804ms
├─── GET <url> in 205ms (cache: SKIP, reason: cache: no-cache)
├────── GET <url> 200 in 0ms (cache: HIT)
├────── GET <url> 200 in 373ms (cache: SKIP, reason: revalidate: 0)
└────── GET <url> 200 in 111ms (cache: SKIP, reason: cache-control: no-cache (hard refresh))
```
Closes NEXT-1412
The PR follows #53146 and #53115.
The PR does 3 things:
- Replaces a [very heavy dependency `cpy`](https://github.com/vercel/next.js/pull/53146#issuecomment-1649193789) with a more lightweight copy helper.
- The `fs.cp(src, dest, {recursive: true})` API is not used, as it is still experimental:

- Update `cross-spawn` to the latest version `7.0.3`
- The only breaking change introduced in `cross-spawn@7.x` is dropping Node.js 8 supports, which allows `cross-spawn` to drop a dependency. Since `create-next-app` requires Node.js 16.8.0, I assume bumping `cross-spawn` would be safe.
- Update `fast-glob` to the latest version `3.3.1` to remove more KiBs (pointed out by @imranbarbhuiya)
- The breaking change introduced in `fast-glob@3.x` is dropping Node.js 8 supports and some options changes.
Together the PR removes another 202 KiB from the `create-next-app/dist/index.js`. The size of `create-next-app/dist/index.js` is now 616 KiB.
<img width="583" alt="image" src="https://github.com/vercel/next.js/assets/40715044/4deb5e36-a63b-4501-b67c-29ea06e30578">
Colocated unit tests (such as ones in `packages/next` and `packages/font`) weren't running in CI since `run-tests` marks the glob cwd as `<root>/tests`. This modifies the working directory to be the root so the new expanded test pattern will pick up files outside of `test/`.
Several of these tests were failing so there are updates in here to fix them. Specifically:
- Source Sans Pro font was renamed to Source Sans 3
- `fillCacheWithDataProperty` test was hitting the `bailOptimistic` code path
- `resolve-metadata` had an invalid assertion (`rel: icon` gets added as part of `IconsMetadata`)
- `resolve-opengraph` wasn't handling undefined images
- `server-patch-reducer` now use inline snapshots as one was failing since it now has a prefetchCache
### What?
Exposing the original error message.
### Why?
While looking at #53279, I noticed that we don't show the original error message, which makes it hard to guess why the error was thrown in the first place.
### How?
Related #53279
This implements the handling for the new `--experimental-turbo` flag
that keeps the Next.js routing handling in front of turbopack and
leverages the new Next.rs API.

This refactors the changes from my previous PR to allow smooth scrolling for the appDir case -- `componentDidUpdate` isn't a reliable way to check if only the hash has changed. This adds a property to `focusAndScrollRef` and compares canonicalUrls (sans hash fragment)

Mark `react-dev-overlay` as an external for the client layer. This
reduces the server bundle by 1 MB (2.5 MB → 1.5 MB) during dev with
fewer resolve calls. Note that it applies to all pages, so this will
have a non-trivial memory improvement potentially.
This PR adds some improved `modularizeImports` rules to ensure that some
of the popular UI libraries (mostly icons) can be correctly optimized
instead of creating thousands of modules. Here's an example of applying
this to `lucide-react`:
With https://github.com/swc-project/plugins/pull/196 being landed, we
can add different transform rules for specific names in the import. For
example, for `lucide-react` there're now 3 transforms:
- `'Lucide(.*)': ...`
- `'(.*)Icon': ...`
- `'*': ...`
On top of that, another critical change made in this PR is the
introducing of `modularize-import-loader`. With this new loader, we can
delegate the task of re-exporting the value to Webpack, where we can
adjust the type of the export and the target path. This is very
necessary and can't be done in SWC alone because libs like
`lucide-react` is using `.mjs` and don't have `exports` values for the
individual icons in the package.json files.
Because of that, if we simply transform the expression to `import Icon
from 'lucide-react/esm/icons/foo` it will fail because:
1. It's missing a `.mjs` extension
2. It doesn't have `/esm/icons/foo.mjs` in package.json `exports`
For 1), in fact that they moved to `.mjs` only in a recent upgrade so we
can't even hard code it to be `.mjs` in the transform (breaks old
versions).
Because of all the above, I decided to go with Webpack's own resolution
logic with the loader as a _temporary_ solution. It's temporary because
it's still assuming that the file structure of these libs doesn't
change.
This uses an IPC server (if available) for incremental cache methods to help prevent race conditions when reading/writing from cache and also to dedupe requests in cases where multiple cache reads are in flight. This cuts down on data fetching across the different build-time workers.

### What?
This reimplements our stream cancellation code for a few more cases:
1. Adds support in all stream-returning APIs
2. Fixes cancellation detection in node 16
3. Implements out-of-band detection, so can cancel in the middle of a
read
It also (finally) adds tests for all the cases I'm aware of.
### Why?
To allow disconnecting from an AI service when a client disconnects. $$$
### How?
1. Reuses a single pipe function in all paths to push data from the
dev's `ReadableStream` into our `ServerResponse`
2. Uses `ServerResponse` to detect disconnect, instead of the
`IncomingMessage` (request)
- The `close` event fire once all incoming body data is read
- The request `abort` event will not fire after the incoming body data
has been fully read
3. Using `on('close')` on the writable destination allows us to detect
close
- Checking for `res.destroyed` in the body of the loop meant we had to
wait for the `await stream.read()` to complete before we could possibly
cancel the stream
- - -
#52157 (and #51594) had an issue with Node 16, because I was using
`res.closed` to detect when the server response was closed by the client
disconnecting. But, `closed` wasn't
[added](https://github.com/nodejs/node/pull/45672) until
[v18.13.0](https://nodejs.org/en/blog/release/v18.13.0#:~:text=%5Bcbd710bbf4%5D%20%2D%20http%3A%20make%20OutgoingMessage%20more%20streamlike%20(Robert%20Nagy)%20%2345672).
This fixes it by using `res.destroyed`.

A bug was introduced in #52843 that causes hydration issues -- this
fixes that by moving the previous logic into the existing `isError` path
that doesn't trigger a call to `hydrateRoot` ensuring we are only doing
this on the client tree

- Replace `chalk` with `picocolors`
- Note that `chalk.hex('#007acc')` has been replaced with `picocolors.blue`
- Replace `glob` with `fast-glob@2.2.7`
- Not only does `fast-glob` is a faster drop-in replacement of `glob` with first-party `Promise`-based API support, but also `fast-glob` is already a dependency of `cpy`:

### What?
closes WEB-1301. To collect some information inside of rust binary, embed it as build-time constant. It supersedes existing target triple embedding as well.
Fixes#52548
This PR fixes the issue of the `<Image />` "blur" placeholder where the
placeholder image appears "washed out" and feathered around the edges.
The fix does NOT involve any API changes - only the underlying SVG
filter is updated.
The filter works for any image type (JPEG, GIF, WEBP) no matter if it
contains transparency or not.
## How it works
```html
<filter id='b' color-interpolation-filters='sRGB'>
<feMorphology in='SourceAlpha' operator='dilate' radius='15' result='dilate' />
<feGaussianBlur in='dilate' stdDeviation='15' result='mask' />
<feGaussianBlur in='SourceGraphic' stdDeviation='20' result='blur' />
<feComponentTransfer in='blur' result='solid'>
<feFuncA type='table' tableValues='1 1' />
</feComponentTransfer>
<feComposite in2='mask' in='solid' operator='in' result="comp" />
<feMerge>
<feMergeNode in="SourceGraphic" />
<feMergeNode in="comp" />
</feMerge>
</filter>
```
Currently the underlying filter uses `feComponentTransfer ` to get rid of the feathered edges but only for JPEG images. This is because if alpha channel was to be mapped to 1 for images with transparency in it, all of the transparent pixels would turn black (which is obviously undesirable).
The way I fixed it is by creating a mask from the SourceAlpha (effectively the "shape" of the object in an image), slightly blurring it for a smoother look (feMorphology + feGaussianBlur), and then clipping the `feComponentTransfer` result to the shape of the mask (`<feComposite in2='mask' in='solid' operator='in' result="comp" />`).
Then finally `feMerge` is used to stack original image and the clipping result from the previous step just to make sure that any left over artifacts from clipping are hidden.
## Result
Here's a comparison between the current implementation (left column), and the filter above (right column)

### What?
Updates the `@typescript-eslint/parser` dependency of `eslint-config-next` to the latest release `6.1.0`.
### Why?
This is blocking NextJS developers from updating their own dependency on `@typescript-eslint/eslint-plugin`, which in turn requires `@typescript-eslint/parser@6.1.0`
### How?
Updated the package.json and ran `pnpm install`. I'm assuming that CI will catch any issues with the update (I know this could be deemed as a bit lazy, so apologies for that. It's all I have time to do at the moment).
setLoading must be "true" at first and then set to "false". The documentation, as is, always has the value of setLoading set to "false".
The purpose of this code is to show "...loading" on the screen while the data is being fetched. In order for this to happen, setLoading must be initially set to "true" and then (after the data is successfully loaded) set to "false", since the line `if (isLoading) return <p>Loading...</p>` is asking if the content is still loading, and if it is, it'll return a message indicating it.
Because of this
### What?
setLoading should be set to "true" at first.
### Why?
Because the code then asks if the content is being loaded. The code (as is) always has setLoading set as "false" and it doesn't show the loading message when it's supposed to.
### How?
I changed the line to `const [isLoading, setLoading] = useState(true)`.
