build(deps): bump github.com/tetratelabs/wazero from 1.0.0-pre.3 to 1.0.0-pre.9

[dependabot]

Bumps github.com/tetratelabs/wazero from 1.0.0-pre.3 to 1.0.0-pre.9.

Release notes

Sourced from github.com/tetratelabs/wazero's releases.

wazero v1.0.0-pre.9 integrates Go context to limit execution time running third party code. This is our last API affecting version before 1.0 in March. We'll cut at least one release candidate between now and then.

For those only interested in breaking changes, here's what you need to do:

• Build with minimally Go 1.18
• Rename Runtime.InstantiateModuleFromBinary to Runtime.Instantiate

mod, err := r.InstantiateModuleFromBinary(ctx, guestWasm)
mod, err := r.Instantiate(ctx, guestWasm)

Those of you attending wasmio will be able to meet many contributors and end users in person. This conference is timed almost exactly with our 1.0 release, so quite convenient for the community. If interested about in-person and virtual activities around our release, join gophers slack #wazero channel. Note: You may need an invite to join gophers. Regardless, if you like what we are doing, please star our repo as folks appreciate it. Meanwhile, let's dig into this month's changes!

Stop runaways with Go context!

@​mathetake led an exciting development, which allows more control of the third-party wasm you run with wazero. Specifically, a cancel or deadline context can now halt potentially endless loops.

Here's an example:

ctx := context.Background()
r := wazero.NewRuntimeWithConfig(ctx, wazero.NewRuntimeConfig().
// Integrate go context with the WebAssembly runtime
.WithCloseOnContextDone(true))
defer r.Close(ctx)
mod, _ := r.Instantiate(ctx, infiniteLoopWasm)
infiniteLoop := mod.ExportedFunction("infinite_loop")
// Add function-scoped timeouts however you like.
ctx, cancel := context.WithTimeout(ctx, time.Second)
defer cancel()
// Pass that context when calling a function to prevent it from looping.
_, err = infiniteLoop.Call(ctx)

When the context is done before wasm returns, you'll get an ExitError with one of these codes: ExitCodeContextCanceled or ExitCodeDeadlineExceeded

It is understood that some would like more features, such as metering or work-based limits. However, we are excited to have the most commonly requested form of function limiting implemented prior to 1.0. Without this last minute spike from @​mathetake, it might not have happened, or ended up as an experiment.

Passing all the tests

Besides features, there has been a large amount of effort to pass all available system tests, on darwin, linux and windows. This means that not only do we pass our own integration tests, but also third party ones like so:

wasi-testsuite

wasi-testsuite is an emerging test suite by the custodians of the WASI (system calls for wasm, basically). These include tests compiled from multiple languages including AssemblyScript, C, rust. Runtimes adapt into the suite, so there's one for wazero similar to wasmtime.
