Unexpected reading file error when working with Bun.build + --hot

[levii-pires]

What version of Bun is running?

1.1.8+89d25807f

What platform is your computer?

Linux 6.8.9-arch1-2 x86_64 unknown

What steps can reproduce the bug?

$ git clone https://github.com/levii-pires/bunsai2
$ cd bunsai2
$ bun install
$ cd examples
$ bun install
$ bun hono:hot

Then you go to bunsai2/examples/src/svelte/test.svelte, make some change and save the file

What is the expected behavior?

Nothing different than the first run

What do you see instead?

After triggering the first reload

Unexpected reading file: "/home/ti/Projs/bunsai2/src/extra/asset.ts"
    at /home/ti/Projs/bunsai2/src/extra/asset.ts

Same problem in Bun v1.1.12! Files exist, however, it's displaying this error after the hotreloading twice 😓

{
  outputs: [],
  success: false,
  logs: [
    error: Unexpected reading file: "/Users/aralroca/Documents/test/src/components/theme-slots.tsx"
 ]

The first time hot reloading works well, but in the second one, it fails.

@levii-pires did you found some workaround to fix it?

@aralroca the problems seems to rise when bun tries to read-and-bundle a file that is also being watched by bun.

yet no workaround...

@levii-pires It also happens to me using import { watch } from “node:fs”; without the --hot, it also happens 🤔

[levii-pires]

@aralroca so its a watch() bug

@aralroca The cool thing is that it is a Linux bug. Not happening on Windows
