# preview2-prototyping

## This repository will soon be retired!

This repository was home to the prototype implementation of Wasmtime's WASI

Preview 2 support for 7 months. We have now landed almost all of this

repository upstream:

* [Wasmtime issue

  #6370](https://github.com/bytecodealliance/wasmtime/issues/6370) describes

  the transition plan, and tracks its progress.

* The component adapter, which used to live at the root of this repo and now

  lives at `crates/wasi-preview1-component-adapter`, has a new home at

  [`wasmtime/crates/wasi-preview1-component-adapter`](https://github.com/bytecodealliance/wasmtime/tree/main/crates/wasi-preview1-component-adapter).

* Published binaries of the component adapter can now be found in the

  [Wasmtime `dev` tag

  assets](https://github.com/bytecodealliance/wasmtime/releases/tag/dev)

  under [`wasi_preview1_component_adapter.command.wasm`](https://github.com/bytecodealliance/wasmtime/releases/download/dev/wasi_preview1_component_adapter.command.wasm)

  and [`wasi_preview1_component_adapter.reactor.wasm`](https://github.com/bytecodealliance/wasmtime/releases/download/dev/wasi_preview1_component_adapter.reactor.wasm).

* If you are invoking `wasm-tools component new` with the component adapter,

  you now need to specify the name to adapt is `wasi_snapshot_preview1`, e.g.

  `wasm-tools component new --adapt wasi_snapshot_preview1=./wasi_preview1_component_adapter.command.wasm`

* The host implementation of WASI Preview 2 was found in this repository's

  `wasi-common` crate. The new home is in the

  [`wasmtime-wasi` crate under the `preview2` module](https://github.com/bytecodealliance/wasmtime/tree/main/crates/wasi/src/preview2).

* If you were vendoring in the `wasi-common` from this repository, change your

  source code's `use wasi_common::{WasiCtxBuilder, WasiView, wasi::Command}`

  to `use wasmtime_wasi::preview2::{WasiCtxBuilder, WasiView, wasi::Command}`

  to switch to the new implementation.

* If you are looking for the tests found under this repository's `host/tests`,

  those now live at

  [`wasmtime/crates/test-programs/tests`](https://github.com/bytecodealliance/wasmtime/tree/main/crates/test-programs/tests).

* If you are looking for the contents of this repository's `test-programs`,

  those now live under

  [`wasmtime/crates/test-programs`](https://github.com/bytecodealliance/wasmtime/tree/main/crates/test-programs).

## Still active in this repository

The `wasi-sockets` implementation in this repository is still a work in

progress. It will land in Wasmtime in the future, but still lives here

for the time being.
