Test Case

Simple hello world example, works fine with wasi preview1, but panic for component model.

seesee.zip

// wit/see.wit
package plugin:see

world see {
  export run: func() -> result
}

// seesee/src/lib.rs
wit_bindgen::generate!({
    path: "../wit/see.wit",
    world: "see",
});

struct Checks;

impl See for Checks {
    fn run() -> Result<(), ()> {
        println!("Hello, world!");

        Ok(())
    }
}

export_see!(Checks);

// part of Cargo.toml
wasmtime = { git = "https://github.com/bytecodealliance/wasmtime", branch = "release-10.0.0", default-features = false, features = [
  "cranelift",
  "component-model",
  "async",
] }
wasmtime-wasi = { git = "https://github.com/bytecodealliance/wasmtime", branch = "release-10.0.0"}

Steps to Reproduce

• new a rust project placed with above code
• run cargo build --target wasm32-wasi --release
• run wasm-tools component newseesee.wasm --adapt wasi_snapshot_preview1=component-type-version-3-f7ae056/wasi_snapshot_preview1.reactor.wasm -o seesee.component.wasm to produce the component wasm file
• run call_run func with api provided by wasmtime crate.

The last step is just a copy of src/commands/run.rs which replaced all related things to component version.

Expected Results

Print the string to stdout.

Actual Results

Versions and Environment

Wasmtime version or commit:

Tried both branch "release-10.0.0" and commit "92024ad11728efa9b3b59b426ebc7cc817cebf6b" which is the last component type version 2 version.

component adapter:

Tried both commit 92024ad (component type version 2, with wasm-tools 1.0.34) and f7ae056 (component type version 3, with wasm-tools 1.0.35) with exactly the same commit of wasmtime and wasmtime_wasi.

Operating system: Linux fedora 6.2.14-300.fc38.x86_64

Architecture: AMD64

Extra Info

The same wasm file works before composing to component with adapter when run following command on all of version 8.0.0, 9.0.0, 9.0.3 and commit 92024ad11728efa9b3b59b426ebc7cc817cebf6b:

Fixed by https://github.com/bytecodealliance/wasmtime/issues/6546 , same reason.

Test Case

Simple hello world example, works fine with wasi preview1, but panic for component model.

// wit/see.wit
package plugin:see

world see {
  export run: func() -> result
}

// seesee/src/lib.rs
wit_bindgen::generate!({
    path: "../wit/see.wit",
    world: "see",
});

struct Checks;

impl See for Checks {
    fn run() -> Result<(), ()> {
        println!("Hello, world!");

        Ok(())
    }
}

export_see!(Checks);

// part of Cargo.toml
wasmtime = { git = "https://github.com/bytecodealliance/wasmtime", branch = "release-10.0.0", default-features = false, features = [
  "cranelift",
  "component-model",
  "async",
] }
wasmtime-wasi = { git = "https://github.com/bytecodealliance/wasmtime", branch = "release-10.0.0"}

Steps to Reproduce

• new a rust project placed with above code
• run cargo build --target wasm32-wasi --release
• run wasm-tools component newseesee.wasm --adapt wasi_snapshot_preview1=component-type-version-3-f7ae056/wasi_snapshot_preview1.reactor.wasm -o seesee.component.wasm to produce the component wasm file
• run call_run func with api provided by wasmtime crate.

The last step is just a copy of src/commands/run.rs which replaced all related things to component version.

Expected Results

Print the string to stdout.

Versions and Environment

Wasmtime version or commit:

Tried both branch "release-10.0.0" and commit "92024ad11728efa9b3b59b426ebc7cc817cebf6b" which is the last component type version 2 version.

component adapter:

Tried both commit 92024ad (component type version 2, with wasm-tools 1.0.34) and f7ae056 (component type version 3, with wasm-tools 1.0.35) with exactly the same commit of wasmtime and wasmtime_wasi.

Operating system: Linux fedora 6.2.14-300.fc38.x86_64

Architecture: AMD64

Extra Info

The same wasm file works before composing to component with adapter when run following command on all of version 8.0.0, 9.0.0, 9.0.3 and commit 92024ad11728efa9b3b59b426ebc7cc817cebf6b:

wasmtime run seesee.wasi.wasm --invoke run
