Not sure what the Linux-only nightly debug failure is, but it's something to do with LSAN. 😬 I don't think I have the bandwidth to figure it out right this moment, though.

ErichDonGubler · 2025-01-10T22:45:59Z

This PR only upgrades windows-* dependencies, though @mxinden had invited me to make them a range dependency instead. The reason I didn't is that while things seem source-compatible between versions of windows-core releases, windows-bindgen's output supposedly changes significantly between the 0.58 and 0.59 versions. I wasn't sure if it was safe to use a range in that case.

It seems that bindgen is/was used to avoid bringing in the windows crate, but I think that should actually be fine to use now in mozilla-central. Was there another reason not to use the windows crate directly? If not, we might be able to use a range over the windows crate itself.

Will be fixed with #69.

@larseggert can you explain why bindgen is used?

larseggert · 2025-01-13T13:31:36Z

In earlier versions, we tried to avoid pulling in the other largerwindows crates by having a static Rust binding file for the few Windows APIs we called, together with a CI test that called bindgen to detect any changes.

We abandoned that at some point, and converted to calling bindgen during build. I don't think there was any reason other than it was a simply change.

If we can avoid bindgen by just using the other windows crates, let's do so, esp. if it makes integration easier.

larseggert · 2025-01-13T13:32:52Z

@ErichDonGubler I don't seem to have the ability to rebase your PR; did you maybe not give owners the relevant permission?

ErichDonGubler · 2025-01-13T14:06:27Z

@larseggert: Huh, that's strange, I'm not sure why you can't rebase. I don't see the Allow maintainers to edit this PR checkbox, but that's normally what I'd check. 🤔

I've rebased using the GH UI.

larseggert · 2025-01-13T14:08:15Z

@ErichDonGubler Thanks for rebasing. Would you want to switch us from the bindgen dep to the other windows deps in this PR?

ErichDonGubler · 2025-01-13T16:05:00Z

@larseggert: Sure!

mxinden · 2025-01-17T19:07:54Z

For what my input is worth here, I am in favor of moving from windows-bindgen to windows, as the former is not yet part of mozilla-central, but the latter is.

While I assume we can bring windows-bindgen into mozilla-central, it will require a cargo vet audit and, more generally, increase our dependency footprint.

@ErichDonGubler I appreciate your support here. Let me know if you need any help.

ErichDonGubler · 2025-01-17T20:09:14Z

Just force-pushed to move to the windows crate, plus an extension to version 0.59. 🙌🏻 Nice, that was easier than I'd hoped it'd be!

ErichDonGubler · 2025-01-17T20:11:20Z

Just made an example showing that windows 0.59.0 can be consolidated into after patching libloading here: erichdongubler-mozilla@3a713aa

You can recreate this commit by: 1. Applying a `patch.crates-io.libloading` to point to the upstream PR allowing `windows` 0.59 in its dep. range. 2. Run `cargo update`.

ErichDonGubler · 2025-01-17T20:17:26Z

🙌🏻 This PR no longer has a hard dependency on libloading's upstream PR to extend its windows dependency version range (nagisa/rust_libloading#169), but an upgrade of libloading after it releases that PR's contents is necessary to allow downstream crates to upgrade to windows 0.59.0.

Thanks for the quick help here @ErichDonGubler! Will make my life a lot easier bringing mtu into mozilla-central!
