@zkat Fixing the MSRV builds may require updating the MSRV to 1.63 or later. Please advise as to how you'd like to proceed.

[zkat]

@waywardmonkeys bumping the MSRV is a semver-major so it should be a separate PR. I'm trying to debate "this is already broken, so an MSRV bump should just be a semver-patch, rather than a semver-major". I really hate having to do semver-major changes for tiny stuff like this.

[waywardmonkeys]

@zkat I agree! I can argue either side of it here, so I didn't know what to do. We can at least get most things fixed and I'll be happy to do what's needed in a follow up PR.

rustix is causing the problem and that's used by is_terminal ... so looking at that, is_terminal bumped MSRV in 0.4.8 from 1.48 to 1.63 where it is now (0.4.9).

We could modify the build for the MSRV to use is_terminal 0.4.7 perhaps?

[zkat]

ugh. See, it feels incredibly rude to do an MSRV bump in a patch release.

I'm ok with locking our is_terminal version to 0.4.7 and just create an issue for removing the lock when we're ready to do a semver-major for miette.

You might want to consider committing a lockfile that has version 0.4.7 of is-terminal, without bumping the version in Cargo.toml. My understanding is that a crate is considered to be compatible with a particular MSRV as long as it is possible to select dependency versions that are compatible with the MSRV and the constraints in Cargo.toml. Cargo usually won't find this set automatically. Hopefully some day we'll have a MSRV-aware solver in cargo and this whole problem will go away :)

[waywardmonkeys]

@Benjamin-L Interesting ... maybe a possible follow up?

[Benjamin-L]

I think pinning the dependency in Cargo.toml is a breaking change. For example, the following now fails to resolve:

[package]
name = "miette-290-test"
version = "0.1.0"
edition = "2021"

[dependencies]
is-terminal = "0.4.8"

[dependencies.miette]
git = "https://github.com/waywardmonkeys/miette.git"
branch = "improve-ci-and-fix-clippy"
features = [ "fancy" ]

The semver docs don't say anything about this situation, however the cargo dependency docs discourage upper bounds on library crates for this reason.

[waywardmonkeys]

It is after midnight here, so tomorrow, I will look at fixing this in the CI scripts, instead of pinning the version like I did here.

[waywardmonkeys]

@zkat @Benjamin-L I pushed a different way to resolve it. What do you think?

[zkat]

I'm fine with this.
