1908375 - Ship exnref

Status: RESOLVED FIXED

(Core :: JavaScript: WebAssembly, task, P1)

Description

[Ryan Hunt [:rhunt]]

The latest exception-handling proposal (which includes exnref) has moved to phase 4. We've already shipped the features in it that are the 'legacy exception syntax', so we just need to ship the exnref subset now.

wast was updated in the tree and that broke our spec test generator.

FYI FF131 MDN docs for this can be tracked in https://github.com/mdn/content/issues/35696

As per comment in https://github.com/WebAssembly/exception-handling/issues/280#issuecomment-2381865896, I am seeking help for the docs update. I can't infer enough from the existing MDN docs to understand how and why this is used. Example/explainer anywhere?

Hi Dave, unless you did all the docs required for this and not just a release note, this isn't complete. Did you, or reach broad agreement no docs required?

Hi Hamish
I probably agree with you, I did look at the existing docs and there was litterally no mention of an of the other Value types that are in this and to be brutally honest my knowledge of WASM is just not good enough to be able to write this and all the other type values. Perhaps we need a subject expert to assist with this.

Thanks Dave - all good. Ryan commented in https://github.com/mdn/content/issues/35696#issuecomment-2388682111 that this has a relatively small audience and there is no right place to put the information for now - so not doing more is absolutely the right decision.
Generally I just think that if we're not going to document anything it is worth making that clear so the decision making is clear and no one asks why you're marking stuff complete that isn't done :-)
