* Log str repr of WASI errno at trace level
This commit refactors `Error` enum, and adds logging of the WASI
errno string representation at the trace level. Now, when tracing
WASI syscalls, we will be greeted with a nicely formatted errno
value after each syscall:
```
path_open(...)
| *fd=5
| errno=ESUCCESS
```
This commit gets rid of `errno_from_nix`, `errno_from_win` and
`errno_from_host` helper fns in favour of direct `From` implementations
for the relevant types such as `yanix::Errno` and `winx::winerror::WinError`.
`errno_from_host` is replaced by a trait `FromRawOsError`.
* Back port changes to snapshot0
* Fix indentation in logs
* Remove the `Context` type from `wasmtime`
This hasn't really ended up being used in all that many places and the
dependencies on it were pretty minimal. This commit removes it in favor
of simplifying its various users a bit and/or leveraging the
`Engine`/`Store` structures where possible.
* Run rustfmt
* Preserve full native stack traces in errors
This commit builds on #759 by performing a few refactorings:
* The `backtrace` crate is updated to 0.3.42 which incorporates the
Windows-specific stack-walking code, so that's no longer needed.
* A full `backtrace::Backtrace` type is held in a trap at all times.
* The trap structures in the `wasmtime-*` internal crates were
refactored a bit to preserve more information and deal with raw
values rather than converting between various types and strings.
* The `wasmtime::Trap` type has been updated with these various changes.
Eventually I think we'll want to likely render full stack traces (and/or
partial wasm ones) into error messages, but for now that's left as-is
and we can always improve it later. I suspect the most relevant thing we
need to do is to implement function name symbolication for wasm
functions first, and then afterwards we can incorporate native function
names!
* Fix some test suite assertions
* Correctly count the number of wasm parameters.
Following up on #1329, this further replaces `num_normal_params` with a function
which calls `is_wasm_parameter` to correctly count the number of wasm
parameters a function has.
* Move is_wasm_parameter's implementation into the trait.
* Move the C API to a separate crate
This commit moves the C API from `crates/api/src/wasm.rs` to
`crates/capi/src/lib.rs` to be located in a separate crate. There's a
number of reasons for this:
* When a Rust program depends on the `wasmtime` crate, there's no need
to compile in the C API.
* This should improve compile times of the `wasmtime` crate since it's
not producing artifacts which aren't always used.
* The development of the C API can be guaranteed to only use the public
API of the `wasmtime` crate itself.
Some CI pieces are tweaked and this overall shouldn't have much impact
on users, it's intended that it's a cleanup/speedup for developers!
* Disable rustdoc/tests for capi
* Review feedback
* Add back in accidentally deleted comment
* More renamings
* Try to fix dotnet build
* Don't require `Store` in `Instance` constructor
This can be inferred from the `Module` argument. Additionally add a
`store` accessor to an `Instance` in case it's needed to instantiate
another `Module`.
cc #708
* Update more constructors
* Fix a doctest
* Don't ignore store in `wasm_instance_new`
* Run rustfmt
This is a breaking API change: the following settings have been renamed:
- jump_tables_enabled -> enable_jump_tables
- colocated_libcalls -> use_colocated_libcalls
- probestack_enabled -> enable_probestack
- allones_funcaddrs -> emit_all_ones_funcaddrs
With all the sleeps between commands, the publish script takes a few
miniutes to run, and it can be easy to forget to create the PR when it
finishes. Add a reminder to be displayed at the end of the script.
This commit moves the cranelift tests and tools from the `wabt` crate on
crates.io (which compiles the wabt C++ codebase) to the `wat` crate on
crates.io which is a Rust parser for the `*.wat` format. This was
motivated by me noticing that release builds on Windows are ~5 minutes
longer than Linux builds, and local timing graphs showed that `wabt-sys`
was by far the longest build step in the build process.
This commit changes the `clif-util` binary where the `--enable-simd`
flag is no longer respected with the text format as input, since the
`wat` crate has no feature gating. This was already sort of not
respected, though, since `--enable-simd` wasn't consulted for binary
inputs which `clif-util` supports as well. If this isn't ok though then
it should be ok to close this PR!
In preparation for eventual support for wasm interface types this commit
moves around a few panics internally inside of conversions between the
`wasmtime` crate and the underlying jit support crates. This should have
any immediately-visible user changes, but the goal is that this'll help
support interface types which means `wasmtime` will have types that are
not supported by wasmtime itself and we'll be able to more gracefully
support that with error messages instead of accidental panics.
* Update to the latest spec_testsuite and dependencies.
Update to target-lexicon 0.10, cranelift 0.54, wast 0.6, faerie 0.14,
and the latest spec_testsuite.
For wast and cranelift-wasm, update the code for API changes.
* Factor out the code for matching f32, f64, and v128.
This takes the idea from #802 to split out `f32_matches`, `f64_matches`,
and `v128_matches` functions, which better factor out the matching
functionality between scalar and vector.
This continues #788 and literally removes the type from the public API
of the `wasmtime` crate, making it inaccessible to the outside world.
Now it's purely an implementation detail, yay!
This commit refactors the `wasmtime-wast` crate to internally make it a
bit more concise with less repetition. Additionally it also improves the
error messages by guaranteeing that all failed tests have context
indicating where the test was defined.
It turns out there was also a bug in the previous implementation where
an `AssertMalformed` directive with a `quote` module would accidentally
skip all further tests. This has now been fixed, and all futher tests
continued to pass except for the `simd_const.wast` test. This test has
been disabled temporarily but once the `wasmparser` and `wast` crates
are updated (being worked on independently) this should be possible to
re-enable.
A few small updates to module creation in preparation for a future PR
which is a bit more invasive here with interface types.
* Move `read_imports_and_exports` to an instance method which configures
fields directly rather than returning a number of fields.
* Call between constructors as much as possible.
* Leverage `Rc::get_mut` which we know will work at module creation time
since we have the only reference.
* Only require `str` in `new_with_name`
It's a bit more idiomatic to have APIs require `&str` rather than
`String`, and the allocation doesn't matter much here since creating a
`Module` is pretty expensive anyway.
* Update a test
