This commit syncs tests with latest wasmtime revision.
As such, it now utilises the `wasmtime-api` crate for
runtime setup.
Closes#126, #127, #128, #129.
This commit provides a fix for `remove_directory_trailing_slashes`
test case on Windows. It adds a missing mapping between the following
WinAPI error code and WASI error:
```
ERROR_DIRECTORY => __WASI_ENOTDIR
```
where `ERROR_DIRECTORY` is thrown when the directory name is invalid.
Accidentally left removed #434 when I meant to add it back in! Updates
the `wast` crate dependency and adds support for translating
`v128.const` instructions to a `RuntimeValue`
Closes#441
* Switch lightbeam from `wabt` to `wast`
Switch from a C++-based `*.wat` parser to a Rust-based parser
* Remove unneeded `wabt` dev-dependency from wasmtime-api
* Rewrite `wasmtime-wast` crate with `wast-parser`
This commit moves the `wasmtime-wast` crate off the `wabt` crate on to
the `wast-parser` crate which is a Rust implementation of a `*.wast` and
`*.wat` parser. The intention here is to continue to reduce the amount
of C++ required to build wasmtime!
* Use new `wat` and `wast` crate names
We iterate over the preopens to present them to the WASI program, so
storing them in a `HashMap` means this order is nondeterministic. Switch
to a `Vec` of tuples instead. This means we don't eliminate duplicates,
but they should be rare.
* deps: bump wasmparser to 0.39.2
This has a bug fix for multi-value Wasm validation that is required for getting
the spec tests passing.

* Update cranelift to 0.46.1 to get multi-value Wasm support
The `cranelift_wasm` APIs had to change a little bit to maintain state necessary
when translating multi-value Wasm blocks. The `translate_module` function now
returns a `ModuleTranslationState` that is borrowed during each function's
translation.
* Enable multi-value proposal's spec tests
This enables all the Wasm multi-value proposal's spec tests other than the ones
that rely on functions having more return values than registers available on the
target. That is not supported by cranelift yet.
* wasmtime-interface-types: always use multi-value Wasm
And remove the return pointer hacks that work around the lack of multi-value.
* Fixes `path_symlink_trailing_slashes` test case
This commit:
* adds a couple `log::debug!` macro calls in and around `path_get`
for easier future debugging
* changes impl of `path_symlink` hostcall to actually *require*
the final component (matching the impl of WASI in C)
* ignores the error `__WASI_ENOTDIR` in `path_get`'s `readlinkat` call
which is not meant to be an error at this stage (i.e., this
potentially erroneous condition *will be* handled later, in
one of the layers above)
* Fixes `path_symlink_trailing` slashes on BSD-nixes
This commit:
* makes `path_symlink` host-specific (Linux and BSD-like nixes
now have their own differing implementations)
* on BSD-like nixes, when `ENOTDIR` is returned from `symlinkat`
it checks whether the target path contains a trailing slash,
strips it, and then checks if the target path without the trailing
slash exists; if yes, then converts the error code to `EEXIST` to
match Linux/POSIX spec
This commit moves a couple of things around:
* separates the logic of `path_unlink_file` into separate impls
for linux and BSD-style nixes
* moves implementation consts into appropriate impl modules: linux
or bsd
* cleans up `utime_now` and `utime_omit` for BSD-style nixes
This commit fixes an issue with incorrect handling of /dev/(u)random
on Linux. It turns out that `nix::unistd::isatty` call handled only
the POSIX spec case where `ENOTTY` is returned in case the passed
in file descriptor is OK but not a TTY, whereas on Linux this is not
always the case. On Linux, it can be the case that `EINVAL` is returned
instead and this case AFAIK is not handled by the `nix` crate. This
commit fixes this by using `libc::isatty` syscall directly and checking
the return values.
* Don't run the spec_testsuite tests if the submodule isn't checked out.
This way, if someone checks out the repository without checking out the
submodules, they can still run "cargo test".
Also, fix a warning in the generated test runner code.
* Print a message if the spec_testsuite submodule is not enabled.
* Move the `#[cfg(test)]` to the top-level `mod`.
* Update the README.md.
Feature the wasmtime.dev website, update WASI content.
With Lightbeam moving into the Wasmtime repo, it's no longer necessary
to use git submodules to build Wasmtime.
* Put misc_testsuite behind a feature gate
This PR puts building and generating of misc_testsuite behind
a feature gate "misc_testsuite". This is mainly to allow projects
which pull `wasi-common` as a dependency not to have to have
`wasm32-wasi` target installed in order to build it as it currently
is.
* Update the CI
* Rename feature to wasm_tests
* Explain integration testing in the README
