build test - ignore

[kennykerr]

This is a smoke test of the next major version of the windows-bindgen crate - this PR is just for validation and will be closed - look for a subsequent PR with a complete description of new features and changes.

Hey @ChrisDenton I added some panic tests to the latest version of windows-bindgen and I'm noticing that std::fs::create_dir_all and std::fs::write sometimes fail silently. Might I be missing something?

https://github.com/microsoft/windows-rs/actions/runs/12060811636/job/33631839763?pr=3354

Both tests that fail to fail.. are not failing inside write_to_file here:

https://github.com/microsoft/windows-rs/blob/vnext/crates/libs/bindgen/src/io.rs

Hm, I've not looked at it closely yet but could that function actually be properly succeeding in CI? Because it's running with admin permissions it could succeed writing in windir.

[kennykerr]

Is it? I also noticed it silently failing locally with the i686 toolchain although sporadically.

[kennykerr]

I'll confirm one way or the other.

[ChrisDenton]

Quick thought: i686 might be affected by wow64 path redirection.

Quick test

pub fn write_to_file<C: AsRef<[u8]>>(path: &str, contents: C) {
    if let Some(parent) = std::path::Path::new(path).parent() {
        std::fs::create_dir_all(parent)
            .unwrap_or_else(|_| panic!("failed to create directory `{path}`"));
    }
    std::fs::write(path, contents).unwrap_or_else(|_| panic!("failed to write file `{path}`"));

    // print the canonical path
    let p = std::fs::canonicalize(path).unwrap();
    println!("{}", p.display());
}

For i686 it outputs: \\?\C:\Users\Chris\AppData\Local\VirtualStore\Windows\output.log

[kennykerr]

OK I'll find a more reliable failure path. 🫠

[kennykerr]

ok everything is green except for the lib tests 👍
