libc VS wazero

I don't think I understand what the argument for that is, because I've only ever heard it articulated as "cgo isn't go" which doesn't really convey much information.

Is this go? https://gitlab.com/cznic/libc/-/blob/master/libc_openbsd.go?...

I mean technically I suppose it is code that conforms to the go language grammar, but I'm not sure why a language purist would accept this.

Maybe you can contribute a fix? The related discussion is here: https://gitlab.com/cznic/libc/-/issues/20

https://github.com/tetratelabs/wazero/releases/tag/v1.7.0

This includes the final release of the new optimizing compiler, which is a big improvement over the previous one.

The new version also adds experimental support for threads and snapshot/restore (setjmp/longjmp).

This is already being used by go-pgquery, all will mean that sqlc won't need to ship to almost copies of wazero (these features had been implemented on a friendly fork, and have now been up-streamed).

Wazero looks super cool. I saw somewhere that programs can be run with a timeout, which sounds great for sandboxing. The program input is just a slice of bytes [1], so an interesting use case would be to use something like Nats [2] to distribute programs to different servers. Super simple distributed computing!

It is slower.

The WASM runtime wazero [1] uses a compiler on amd64 and arm64 (on Linux, macOS, Windows, and FreeBSD), but the current compiler is very fast (at compiling), but very naive (generates less than optimal code).

An optimizing compiler is currently being developed, and should be released in the coming months. I'm optimistic that this compiler will cover the performance gap between WASM and modernc.

I am a fan of the Jacobin project! For your uses, you may also want to consider wazero [1], a pure-go WebAssembly runtime. Full disclosure: I am on the team :)

No longer does Wasm/WASI need JS host! There are many spec-compliant runtimes built for environments from tiny embedded systems up to beefy arm/x86 racks:

- https://github.com/bytecodealliance/wasmtime

- https://github.com/wasmerio/wasmer

- https://github.com/tetratelabs/wazero

- https://github.com/extism/extism (disclaimer, my company's project - makes wasm easily embeddable into 16+ programming languages!)

full disclosure: I don't work on it, but the devs are committers/contributors to https://wazero.io (I am a wazero committer) :)
