I do not understand why https://github.com/rust-osdev/uefi-rs/actions/runs/3455556833/jobs/5767663192 fails. I'm seeking your advice @nicholasbishop @GabrielMajeri

I do not understand why rust-osdev/uefi-rs/actions/runs/3455556833/jobs/5767663192 fails.

As far as I can tell, the issue is in a doctest we have in the uefi-macros crate. It's meant to check that the #[entry] macro works as advertised, but for some reason, Rust is complaining about the lack of a global allocator in the test binary which gets generated (pretty irrelevant for us, since we don't want to actually run that code).

I'm not sure why it's showing up right now (changes in the latest nightly?), but I've found that it compiles successfully if we remove the #![no_std] attribute and the panic handler.

/// ```no_run
/// #![no_main]
/// #![feature(abi_efiapi)]
/// # // A bit of boilerplate needed to make the example compile in the
/// # // context of `cargo test`.
///
/// use uefi::prelude::*;
///
/// #[entry]
/// fn main(image: Handle, st: SystemTable<Boot>) -> Status {
/// Status::SUCCESS
/// }
/// ```

Add resolver = 2 to the [workspace] section as described in https://doc.rust-lang.org/cargo/reference/resolver.html#resolver-versions. That should resolve the error since the alloc feature won't be enabled in uefi for that test.

I do not understand why it builds in the CI but no longer locally..

Any idea? cargo clean also doesn't help. I tested multiple nightly versions..

Are you running cargo check? That's not something the CI runs. Since there's no longer a top-level package it's now checking the whole workspace instead of of just the uefi package. This was already broken before your change, you just would have had to run cargo check --workspace to see the error. I think it's fine for it to remain broken for this PR, we could look at fixing that command separately.

Very cool! I'm glad we could merge this.
