Bumps github.com/tetratelabs/wazero from 1.0.0-pre.7 to 1.0.0-pre.8.

Release notes

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

wazero v1.0.0-pre.8 adds a filesystem configuration API that supports writes, tested by multiple third-party suites. It also brings CompilationCache out of experimental state, obviating a hard to explain Namespace API. Finally, this adds more logging scopes.

We don't expect any API changes next month, as we prepare for wazero 1.0 in March. Most of the scheduled work will be completing WASI and improving tests, so that our first formal release is trustworthy. Please upgrade to this version and give us feedback on how it's going.

The best way to contact us is to join gophers slack #wazero channel. Note: You may need an invite to join gophers. If you like what we are doing, please star our repo as folks appreciate it. Meanwhile, let's dig into this month's changes!

Writable filesystem support

An exciting change for many is the ability to configure writeable filesystems. To do that, we've added ModuleConfig.WithFSConfig which has options to mount directories or a fs.FS such that wasm can access it. Before, we had ModuleConfig.WithFS, and we'll leave that forever. This will help reduce complexity for simple-case configuration.

Here's an example of how to allow read access to the current directory as the root filesystem, while write access to a different directory as "/tmp"

moduleConfig = wazero.NewModuleConfig().
    // Make the current directory read-only accessible to the guest.
    WithReadOnlyDirMount(".", "/")
    // Make "/tmp/wasm" accessible to the guest as "/tmp".
    WithDirMount("/tmp/wasm", "/tmp")

Under the scenes, this maps to appropriate WebAssembly primitives, namely "preopens" for those compiling WASI or a virtual root if GOOS=js.

Those using the wazero CLI can take advantage of this with mount-based syntax, which looks very similar to Docker.

For example, here's the same configuration via the command line:

$ wazero run -mount=.:/:ro -mount=/tmp/wasm:/tmp ...

Under the scenes is more comprehensive than last time. Those compiling source via WASI or GOOS=js can take advantage of newly supported system calls, tested on Linux, MacOS and Windows operating systems. Thanks very much to @​codefromthecrypt @​evacchi @​mathetake and @​ncruces for collaborating on these!

  • fd_sync
  • fd_tell
  • fd_pwrite

Some of you may wonder about our progress on a custom filesystem plugin. We have plans to do that, but after version 1.0. This configuration API was designed to be forwards compatible with a raw filesystem plugin once it is ready.

Standard Library Integration Tests

For the first time, wazero change depends on 3rd party integration tests for aspects beyond the WebAssembly Core specification. Specifically, we use multiple tests to ensure WASI not only works based on what the spec leads define, but also work in practice in TinyGo and Zig programming languages. By running multiple tests we are able to get an implicit quorum of what certain functions are expected to do, and reduce the amount of surprise by end users who simply want things to work.

For example, we use wazero instead of wasmtime to run TinyGo wasi target tests. If any fails, our build breaks. We are nearly there with Zig, too, and will be by next month. Both of these are also thanks to the language communities themselves, who have helped champion patches needed to make things portable.

We also run the emerging wasi-testsuite, defined by the spec team. We pass tests they define for the AssemblyScript and C programming languages. We don't yet pass all rust tests recently added from wasmtime: 5 fail mostly due to some edge case functions we've not yet implemented. However, we expect to pass all of them by 1.0 or sooner, or have a very good reason if we don't.

Beyond WASI, we also test the GOARCH=wasm GOOS=js platform baked into the standard Go sdk. This is typically tested via the node.js runtime (which uses V8), but our CLI works in lieu of that also. As Go considers this experimental, we don't require passing all tests, yet. That said we test each function that also exists in WASI. This helps existing users of GOARCH=wasm GOOS=js as well paves an easier transition for those working on the upcoming Go WASI proposal.

Getting these tests understood and integrated into our CI took a lot of effort, with special thanks to @​achille-roussel @​evacchi and @​mathetake for their hard work.
