lib,src: implement WebAssembly Web API #42701

tniessen · 2022-04-12T03:04:20Z

Now that we have fetch(), we may as well also have WebAssembly.compileStreaming() and WebAssembly.instantiateStreaming().

Unfortunately, our fetch() implementation cannot be interacted with easily from C++, which is why part of this implementation ended up in JavaScript. The C++ glue code allows controlling the v8::WasmStreaming instance from JavaScript.

This attempts to be a spec-compliant implementation with no node-specific extensions.

Refs: #41749
Fixes: #21130

unless i am mistaken, these methods do not allocate. would you be up for adding fast call wrappers? if not i can maybe add them in a followup pr.

Will try that tomorrow. So far, every time I tried using fast calls, I can into some V8 limitation, but Push might be a good candidate for once.

On second thought, given how web streams are performing so far and how slow everything is, that seems like premature optimization. I might create a follow-up PR to add that or I might push that as a separate commit later, but I'd like to get this landed rather sooner than later and not make it more complicated to review.

Should we add WTP tests? Maybe https://github.com/web-platform-tests/wpt/tree/HEAD/wasm/webapi or a subset of it?

Should we add WTP tests?

That's a good idea. It's not straightforward because many WPT tests for this API rely on fetch and we currently mock fetch in WPT.

Of the ones I can run easily, wasm/webapi/empty-body.any.js is failing, presumably due to nodejs/undici#1345.

I think you can create a status file that lists all the failing tests, and that can be used as a TODO list for contributors who want to improve Node.js API compliance. But maybe that's a lot of work (I've never done that myself so not sure), and it probably should not block this from landing.

Node landed `WebAssembly.compileStreaming` and `instantiateStreaming` in nodejs/node#42701 and made it available in Node 18, so we no longer need to exclude these properties from our WebAssembly endowment. This PR therefore removes the WebAssembly endowment factory, which will now be included in whatever form it exists on the execution environment root realm global.

juanarbol · 2022-05-31T03:55:05Z

I think it's fine to land it on v16.x, because it's behind the --experimental-fetch flag.

Yeap, it does, It lands fine; except for the bootstrap, tried to fix this by adding the binding wasm_web_api to lib/internal/bootstrap/loaders.js with no sucess, I will label this to request backport:
