* Refactor the `types.rs` types and structures
A few changes applied along the way:
* Documentation added to most methods and types.
* Limits are now stored with the maximum as optional rather than a
sentinel u32 value for `None`.
* The `Name` type was removed in favor of just using a bare `String`.
* The `Extern` prefix in the varaints of `ExternType` has been removed
since it was redundant.
* Accessors of `ExternType` variants no longer panic, and unwrapping
versions were added with "unwrap" in the name.
* Fields and methods named `r#type` were renamed to `ty` to avoid
requiring a raw identifier to use them.
* Remove `fail-fast: false`
This was left around since the development of GitHub Actions for
wasmtime, but they're no longer needed!
* Fix compilation of the test-programs code
* Fix compilation of wasmtime-py package
* Run rustfmt
* Tweak the API of the `Val` type
A few updates to the API of the `Val` type:
* Added a payload for `V128`.
* Replace existing accessor methods with `Option`-returning versions.
* Add `unwrap_xxx` family of methods to extract a value and panic.
* Remove `Into` conversions which panic, since panicking in `From` or
`Into` isn't idiomatic in Rust
* Add documentation to all methods/values/enums/etc.
* Rename `Val::default` to `Val::null`
* Run rustfmt
* Review comments
Previously, "_start" was run as part of module instantiation, which
meant it was always run, even for wasm modules that weren't being
loaded as commands. Now, just invoke it from the wasmtime driver,
which for now is the only place that runs wasm modules as actual
commands.
Also, stop recognizing the old "main" entry point, which tools have
stopped using a while ago, and switch to start recognizing the ""
entrypoint.
For Windows release builds, the `wasm_valtype_kind` C API return value
is being returned as a single byte.
The .NET interop signature for this function was expecting an
integer-sized return, resulting in three extra bytes being used on
Windows.
The fix is to limit the corresponding C# enum to a byte representation,
which will properly mask the return value from `wasm_valtype_kind`.
CI has also been updated to test both debug and release configurations
(previously it was only testing debug, hence why this was missed).
Also fixed a cast bug in the `declare_vec!` macro in the C API when the
element types were pointers to values. The `as_slice` implementation
was incorrectly casting away a level of pointer indirection, resulting
in corrupted data when accessing the slice's elements.
Rust's recent update to libstd of the wasm32-wasi target turned out to
be buggy with respect to fetching the process arguments, so we'll need
to wait on a fix there before we can run these tests with nightly again.
This introduces a script that has a high probability of failing if the
Rust source code generated by the meta crate is not consistent accross
build script runs.
It also adds a new CI job to run it on each push, on a single platform.
* Deny warnings in the CI by default
This commit passes `-D warnings` flag to `rustc` in the Test stage
of the CI in order to deny warnings on _all_ tested platforms.
* Fix warnings
* Fix warnings
This doesn't have libFuzzer generate new inputs in CI, only verifies that we can
still successfully process our existing seed inputs in each of our targets'
corpora.
This commit fixes the CI by setting `actions/checkout` at version `v1`.
The current master of `actions/checkout` now obsoleted the
`with: submodules: true` input.
