Wasmtime GitHub notifications bot (Jan 20 2024 at 15:49):badeend opened PR #7802 from badeend:no-sync2 to bytecodealliance:main:
Fundamentally, preview2 is fully synchronous. So at least in theory there should be no need for all the Sync constraints. In practice it took me a while to figure out how to actually make it work. In summary:
- Removed many
+ Syncconstraints- Removed the immutable reference accessors on WasiView. I also dropped the _mut suffix for consistency with WasiHttpView.
- Had to do a bit of refactoring in
crates/wasi/src/preview2/host/filesystem.rshere andcrates/wasi/src/preview2/preview1.rshere to make them play along.

Needing a mutex here is a minor bummer, but I think the next refactor is to make there be two different ctx structs:
Hostfor all preview 2 compatible things, andLegacyHostfor using wasi-common if, and only if, threads are required.I am working on a PR that separates out wasi-common from wasmtime-wasi, so that we can ship just the preview 2 implementation without any of the old one, so I'll fix this up after that lands.

Yeah, but at least
.lock()never gets called, so effectively it's mostly a Box

There were some build errors specific to Rust version 1.73 (and lower probably).
This should be good to go again.
