* 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.
https://github.com/yurydelendik/wasmparser.rs/pull/135
* 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
This adds a `--always-lightbeam` option as well as an `--always-cranelift`
option, to allow the compilation strategy to be selected via the
command-line. This also enables regular testing for Lightbeam.
This fixes the memory leaks in the following functions which should not be
returning "owned" pointers:
* `wasm_extern_as_func`
* `wasm_func_as_extern`
* `wasm_extern_as_global`
* `wasm_global_as_extern`
* `wasm_extern_as_memory`
* `wasm_extern_as_table`
Additionally, this commit implements the `wasm_memory_as_extern` and
`wasm_table_as_extern` functions.
Fixes#394.
In trying to build the lightbeam feature in wasmtime there are
compile errors mostly related to outdated or missing trait
definitions. This patch moves the current cranelift codegen
dependence to 0.44 in support of that, though other changes
are still needed in wasmtime to get the feature to build.
