wazero compiler cache to disk flag

wapc-guest-tinygo

wapc-guest-tinygo now allows wapc.ConsoleLogger, which uses the host functions implemented by wapc-go.

wazero engine

wazero now adds an experimental context flag that can be used to cache the compiler cache to disk, helping with cold start performance.

Ex.

	engine := wazero.Engine()

	ctx := experimental.WithCompilationCacheDirName(context.Background(), "/home/me/.cache/wazero")
	module, err := engine.New(ctx, host, guest, &wapc.ModuleConfig{
		Logger: wapc.PrintlnLogger,
		Stdout: os.Stdout,
		Stderr: os.Stderr,
	})
--snip--

Module configuration using `io.Writer` and customization of the wazero runtime

The New method of Engine is now:

New(ctx context.Context, host HostCallHandler, guest []byte, config *ModuleConfig)

Where ModuleConfig is

// ModuleConfig includes parameters to Engine.New.
//
// Note: Implementations should copy fields they use instead of storing
// a reference to this type.
ModuleConfig struct {
	// Logger is the logger waPC uses for `__console_log` calls
	Logger Logger
	// Stdout is the writer WASI uses for `fd_write` to file descriptor 1.
	Stdout io.Writer
	// Stderr is the writer WASI uses for `fd_write` to file descriptor 2.
	Stderr io.Writer
}

Additionally, the wazero engine can be customized using EngineWithRuntime.

// NewRuntime returns a new wazero runtime which is called when the New method
// on wapc.Engine is called. The result is closed upon wapc.Module Close.
type NewRuntime func(context.Context) (wazero.Runtime, error)

// EngineWithRuntime allows you to customize or return an alternative to
// DefaultRuntime,
func EngineWithRuntime(newRuntime NewRuntime) wapc.Engine {
	return &engine{newRuntime: newRuntime}
}

Version bumps

v0.4.4

Updates for the latest version of as-guest. (#33)

Version bumps

v0.4.3

Updating dependencies

Close returns error

Makes Close return error and fixes some safety issues (#28)

* Makes Close return error and fixes some safety issues

This makes Close more safe in the non-wazero impls by using atomic
instead of field check to see if a function should proceed.

This also makes "error ignoring" a decision of the caller of `Close` vs
an implicit decision inside an implementation.

What's Changed

• wazero: updates to latest API by @codefromthecrypt in #21
• wazero: WithFeatureSignExtensionOps by @pkedy in #22

Full Changelog: v0.4.0...v0.4.1
