This commit removes the two fuzz targets that we imported from cranelift
when cranelift merged in. These have both uncovered a few issues in the
fuzz targets themselves, for example:
* `translate_module` - this doesn't verify the wasm is valid a head of
time and cranelift is known to panic on translating invalid wasm
modules. We also already do a lot of fuzzing of translation of wasm
modules, so this isn't necessarily buying us anything over what we're
already fuzzing.
* `reader_parse_test` - discovered in #1205 we already found some "bugs"
in this but it may not necessarily rise to the level of "needs to be
run on oss-fuzz for us to find more bugs" yet. It looks like this is
still somewhat internal so we can re-enable when we've got folks to
fix the fuzz bugs coming in.
Closes#1205
* Add a wasmtime-specific `wasmtime_wat2wasm` C API
This commit implements a wasmtime-specific C API for converting the text
format to the binary format. An upstream spec issue exists for adding
this to the C API, but in the meantime we can experiment with our own
version of this API and use it in the C# extension, for example!
Closes#1000
* Reorder arguments
* Use wasm_byte_vec_t for input `*.wat`
* Mark wat input as const
* Return an error message and use `fixed`
* Actually include the error message
* Use `fixed` in `Module.cs` as well
* rename PassiveElemIndex to ElemIndex and same for PassiveDataIndex (#1411)
* rename PassiveDataIndex to DataIndex
* rename PassiveElemIndex to ElemIndex
* Apply renamings to wasmtime as well
* Run rustfmt

wasmtime is covered by oss-fuzz which should cover large swaths of
cranelift as well, so let's remove that from CI and add it back later if
it's necessary.
Jitdump was using an api consisent v0.04 for target_lexicon instead
of the version v0.10. This updates calls to target_lexicon to be
consistent with v0.10.
* Spice up the project README, fill out more docs
This is an attempt to spruce up wasmtime's README.md file as well as
fill out more of the missing documentation in the `docs/` folder.
There's still a long way to go but I hoped here to mostly move around
existing information and add new information. As always happy to have
feedback!
* Tweak CLI wording
* Remove no-longer relevant clause
* Update sandboxing docs
* Handle comments
This is useful for me because I name the module after the file, which
comes from the filesystem and may not be valid UTF8.
This change is backwards-compatible.
This commit changes the C API function `wasm_module_new` to use the Rust API
`Module::from_binary` which performs verification of the module, as per the C
API spec.
This also introduces a `EngineBuilder` type to the C# API that can be used to
construct an `Engine` with the various Wasmtime configuration options. This
is required to get the C# tests passing since they use reference types and
multi-value.
Fixes#859.
This is intended to be a form of release notes for wasmtime where we can
keep track of what's changed over time in a more dense way than `git
log` that should be interesting for most users.
