Tests have been inconsistent due to flaky build-time failures caused by
AMP validation errors:
https://github.com/vercel/next.js/actions/runs/11807856104/attempts/1.
We’re updating the library version with the expectation that this will
resolve the issue.

Note that this failure breaks the production integration test almost 10%
of times.
We will wait the server to respond with a compile success message after
a file is patched before proceeding to the next steps in the test to
reduce flakiness.
By doing so, we uncovered a few tests that were passing accidentally due
to flakiness of `patchFile`, and fixed them in the PR.
This enables DevTools (e.g. Chrome debugger) to collapse stackframes from 3rd party dependencies.
Webpack only. Turbopack added support in https://github.com/vercel/next.js/pull/71770. Replays from RSC will follow.
Had to fork `EvalSourceMapDevToolPlugin` (with blessing from @sokra) to be able to inject `ignoreList`.
For `source-map`, we can use https://github.com/mondaychen/devtools-ignore-webpack-plugin/ instead since we can operate on the assets on disk. I inlined it to iterate on it faster. Though it'd be faster for bundling to also fork `SourceMapDevToolPlugin` since `DevToolsIgnorePlugin` adds another parse/serialize roundtrip.
## test plan
We'll start leveraging `ignoreList` in the terminal as well which will allow us to write automated tests. I haven't found a way to automatically test this ignore-listing in browsers.
Note that this is on Chrome Beta. Chrome Stable does not ignore-list logged stacks yet. Only stacks of the actual `console` call or in the debugger.
(the frame from our console instrumentation is a bug that may be fixed once we populate our own sourcemaps)
`pnpm debug dev test/e2e/app-dir/server-source-maps/fixtures/default/`
`/ssr-error-log` shows
browser:
Node.js debugger doesn't seem to work. Will look at that in a follow-up
We already create server source maps in dev by default,
so we should make use of them.
To opt-out, run `next dev --disable-source-maps` instead.
Our internal `next-no-sourcemaps` script is now defunct.
Currently we only log warnings when we fail to parse config values and
then fall back to their defaults, this is very dangerous as this can
cause unexpected behavior and the warning log can be easy to miss. To
prevent this unexpected behavior this updates to treat these as errors
instead and fails the build if any invalid config exports are provided.

## What
This PR introduces a new API `onRequestError` in `instrumentation.js`
convention, which can help you track the errors thrown from pages and
routes on server side.
### API
```ts
type RequestInfo = {
url: string
method: string
headers: Record<string, string | string [] | undefined>
}
type ErrorContext = {
routerKind: 'Pages Router' | 'App Router'
routePath: string
routeType: 'render' | 'route' | 'middleware'
}
export function onRequestError(error: unknown, request: RequestInfo, errorContext: ErrorContext) {
}
```
This experimental feature is now scoped behind an experimental env var
`__NEXT_EXPERIMENTAL_INSTRUMENTATION` now. You need to enable to use it
before the feature is fully ready off from experimental.
## Why
The purpose is to provide a way to track the server errors from Next.js
much easier, especially when users're uing an o11y provider such as
sentry/datadog/newrelic etc. to monitor server side exceptions. There're
different runtime (Node.js or Edge) and different type of routes (App
Router pages/API routes, Pages Router pages/API routes, middleware) that
makes the error tracking story more complex. This API will be an
universal way to get all the errors.
The reason of providing the related arguments like request info and
error context is aimed to provide more insights about associated
request, also the context about Next.js framework itself, like which
feature is throwing the error.
...with `assertHasRedbox` and `assertNoRedbox`.
`hasRedbox()` has a hardcoded timeout of 5s that is only required for
the negative assertion.
Instead, we now have dedicated assertions for the positive
(`assertHasRedbox`) and negative case (`assertNoRedbox`).
The negative assertion still has the hardcoded timeout.
But the positive assertion just retries until we find the Redbox.
This speeds up tests using the positive assertion.
Removing `hasRedbox` also uncovered some unused expressions e.g. `await
hasRedbox(browser)`.
These expressions probably wanted to use `expect(await
hasRedbox(browser)).toBe(true)
### Description
This PR refactors existing `analysis/get-static-page-info`, moves over
most of parse / ast visiting logic into next-swc's rust codebase. By
having this, turbopack can reuse same logic to extract info for the
analysis. Also as a side effect, this removes JS side parse which is
known to be inefficient due to serialization / deserialization.
The entrypoint `getPageStaticInfo` is still in the existing
`get-page-static-info`, only for extracting / visiting logic is moved.
There are some JS specific context to postprocess extracted information
which would require additional effort to move into.
Closes PACK-2088
When errors are thrown in middleware it could re-send headers for the same response

Migrate middleware-errors test to e2e test to avoid flaky assertion due to duplicated logging collected in integration test.
Closes NEXT-1629
