i think it is finally time to learn how to write a nixos test

I spent this weekend writing a test for the crosvm functionality Spectrum relies on (Wayland over vhost-user-gpu). crosvm upstream moves very fast, and things change/break very frequently, so it's really hard to stay up to date, and hopefully this will help. I'm especially looking forward to much easier bisects now that it won't be a manual process.#spectrumos

Testing this sounds easy, but isn't. The idea is to run a Wayland compositor, and crosvm, with a VM image that opens a Wayland window over virtio-gpu, and then check that that window is displayed in the compositor.But how do you find out when the compositor shows a new window? Sway has config hooks for it, but wlroots doesn't support software rendering in a crosvm-friendly way, which would mean the test couldn't be run in CI.#spectrumos

So the solution I came up with was to use Weston, with a custom plugin that listens for the expected window appearing, and writes into a fifo when it does. The test runner can then just wait to receive data over the fifo, with a timeout in case something in the setup is broken and the window never appears.#SpectrumOS

Other things I did in this, the most productive weekend ever:• Fix logs not being stored in the Spectrum binary cache.• Sent v2 of a kernel patch to fix userspace notifications for loop device partitions.• Some new/improved documentation.:D#SpectrumOS

Here's the test I'm so proud of. There's a #NixOS test that runs #Weston and #crosvm and listens on the fifo, and the custom Weston plugin to write into the fifo when the window appears.One really cool thing about the NixOS test runner is that it can output screenshots, so I can also confirm visually that the test worked.#SpectrumOShttps://spectrum-os.org/git/spectrum/tree/release/checks/wayland?h=wayland

do you use appimages? what applications? is appimage your preferred choice, or more of an "if there's no other option" sort of thing? :BoostOK:

I've been looking into what it would take to add easy AppImage support to #SpectrumOS. AppImage is an attractive thing to integrate first because there's no shared file store to worry about. But it seems like most popular applications are not distributing AppImages (any more), and very few of them include the libraries they need for Wayland, even when the application supports Wayland.

I was also surprised to learn that AppImages don't contain all of their dependencies. They contain some of their dependencies, but it's up to the developer to guess which ones they should include based on what their users are likely to have installed. So unlike with e.g. Flatpak it's impossible to guarantee compatibility.

Linux 6.3 has two commits from me in it and I'm feeling proud. :3One fixes a small amount of debug info being included in kernel images that were supposed to be stripped on x86_64 and RISC-V (which was especially problematic for Nixpkgs because it caused an output cycle).The other fixes userspace not being notified about the new partitions in some cases when a loop device was set up.

@erincandescent @galibert @marcan AIUI, the protocol also doesn't _technically_ require the two to be colocated, but we haven't really seen a system where they aren't. Closest is River (a compositor), which can outsource some WM decisions to another process using a custom Wayland protocol.

Working on NixOS modules is burnout fuel for me, because we don't have a good way to manage state migrations. Modules either accumulate ad-hoc shell code to migrate old state from arbitrarily old Nixpkgs versions, or problems that would require state migrations just don't get fixed.It's a huge difference to pkgs/, where there's zero state to worry about. We can aggressively refactor, and mistakes that weren't caught in review don't matter — they can just be fixed later.

#NLnet / @NGIZero grantees in Germany — how do you handle VAT? They're pretty clear they don't expect their donations to be VATable, but I've been having trouble convincing a Steuerberater of that, so if I can't do that I'm going to be stuck paying the VAT myself. (I know they wouldn't be in scope for VAT in the UK, because the UK's VAT rules are in English and I can read them.) #NextGenerationInternet

Coming soon to #SpectrumOS — double click an AppImage, and it runs in a temporary VM, with no other setup required.Just need to tidy up the commits a bit…

Why AppImage — it's not a very relevant format, right?I chose AppImage because it's very simple — I don't have to figure out what parts of an OSTree store like I'd have to with Flatpak. As a result of how simple it is, I had to write almost no AppImage-specific code — the vast majority of the work was generic, like implementing support for creating VMs on the fly rather than requiring them to all be defined at boot. So this is also step 1 towards supporting other app formats!

I don't think this is how COSMIC is supposed to look but wow I love it
