Layout groups causing import.meta.glob to fail to find files

[hyyyper]

Describe the bug

This code does not returning anything when inside a layout group:

export async function GET() {
    const glob = import.meta.glob("../**/*.md")
    console.log("(web) glob...")
    console.log(glob)

    return new Response(JSON.stringify({ glob: Object.keys(glob) }))
}

In the repro, I made two routes that do the exact same thing...
(web)/blog/posts.json/+server.js
/it-works/blog/posts.json/+server.js

But it only works outside of the (web) layout group. 🤔

I can confirm this bug.

Just a quick update, I tried ../../**/+page.svx instead of ./**/+page.svx and it works!

Not sure why the path changed, but I'll take that for now.

First investigations suggest it's a bug in fast-glob, since that one doesn't return any results for the glob. My guess is that at some point a regex is used and it doesn't escape the ( and ) characters. If I escape them myself it works as expected. Edit: This seems like a bug in Vite after all (thanks @dominikg!) since fast-glob treats some characters as special (like ( or )) and Vite needs to escape them before passing it on. Edit 2: Got the culprit in the vite codebase, it's the toAbsoluteGlob method not escaping things in the path leading up to the glob. Upstream issue created: vitejs/vite#9833

workaround: use a / at the start so vite only prepends the root directory, then you can add the needed escapes yourself

import.meta.glob('/src/routes/\\(name\\)/**/*.md')
