Deny `wasm_c_abi` lint to nudge the last 25% #129534

workingjubilee · 2024-08-24T22:40:46Z

This shouldn't affect projects indirectly depending on wasm-bindgen because cargo passes --cap-lints=allow when building dependencies.

The motivation is that the ecosystem has mostly taken up the versions of wasm-bindgen that are compatible in general, but ~25% or so of recent downloads remain on lower versions. However, this change might still be unnecessarily disruptive. I mostly propose it as a discussion point.

cc @daxpedda Thoughts?

I was considering opening a stabilization PR soon, but I think doing this first is a good idea.

IIRC this lint opts out of this by being a "report in deps" FCW, right?

workingjubilee · 2024-10-03T04:06:53Z

hm. perhaps I misunderstood something then about the interactions here?

daxpedda · 2024-10-03T09:04:32Z

I played around with this a bit, but I couldn't actually see any difference between deny and warning no matter if the dependency is direct or indirect, they all end up as FCW warnings. But compiling old versions of wasm-bindgen directly does trigger a deny lint.

So this change only affects compiling wasm-bindgen directly, but not as a dependency, ergo unfortunately this PR doesn't do anything practically useful :/

I assume this needs a change in Cargo as well to work as intended?
https://github.com/rust-lang/cargo/blob/8725e78484d62c4dd0ef22bb64fb22e4af2f4a1c/src/cargo/core/compiler/future_incompat.rs#L421

workingjubilee · 2024-10-03T19:09:21Z

...well, at least it doesn't break anyone! 🫠

bjorn3 · 2024-10-03T20:17:43Z

Isn't the code that has the ABI incompatibility produced by macro expansion of #[wasm_bindgen] inside the user crate? So it would warn for every user of an old version of wasm_bindgen, but be silenced when the user of wasm_bindgen is itself a non-local dependency.
