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 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.

• Published binaries of the component adapter can now be found in the Wasmtime dev tag assets under wasi_preview1_component_adapter.command.wasm and 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.

• 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.

• If you are looking for the contents of this repository's test-programs, those now live under wasmtime/crates/test-programs.

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.
