alexcrichton opened PR #7597 from alexcrichton:slim-proxy to bytecodealliance:main:

This commit aims to address a discrepancy in Wasmtime where the world supported by wasmtime serve is too large today. This includes WIT interfaces which are not specified in wasi:http/proxy such as wasi:filesystem/types, aka access to a filesystem.

This commit slims down wasmtime serve to, by default, only supporting the wasi:http/proxy world. Like with wasmtime run various CLI flags can be passed to enable more interfaces, however:

• -Scommon - this enables "common" interfaces such as wasi:filesystem, wasi:sockets, and wasi:cli/*.
• -Snn - this enables wasi-nn

It's expected that more will get extended here over time too.

This change is enabled by a third build of the adapter, a "proxy" mode. In this mode most functions are cfg'd to return ERRNO_NOTSUP to indicate that the runtime does not support it. Notably this includes the filesystem, arguments, and environment variables.

This change is tested by updating all api_proxy* tests to use this new adapter which is now required that many previous interfaces are no longer present by default in the proxy world.
