Support MS Windows? 🪟

[michalrus]

The problem

It's not currently possible to compile Acropolis for Windows, because caryatid_process does use tokio::signal::unix, which is not available on Windows:

caryatid/process/src/process.rs

Line 10 in a0c2fa3

use tokio::signal::unix::{signal, SignalKind};

Just tokio::signal::unix seems like it should be relatively easy to make work on Windows, and there are various workarounds.

But maybe there are other similar assumptions?

See also this Slack thread.

How to reproduce on Linux

You can run this:

❯ nix build -L github:input-output-hk/acropolis/pull/266/head#acropolis-process-omnibus-x86_64-windows

It was first detected as part of:

• Add a Nix flake with a devshell, and package builds acropolis#266

I've moved this to Caryatid because it's a generic problem. If this is our only Windows issue then I'm happy!

What is the Windows equivalent to waiting for SIGTERM to do a clean shutdown? Maybe there is a generic crate that would do this?

ChatGPT suggests tokio::signal::ctrl_c()

Yes, we also use it in blockfrost-platform :)
