CompileErrror when initializing the wasm driver

CompileError: wasm validation error: at offset 7591: can't import/export mutable globals in the MVP

I am getting the above error when initializing the wasm driver with the latest canary build.

This is a runtime thing, which I could possibly fix by not running wasm-opt at all I think. This is in Zotero/Firefox ESR, right?

[adomasven]

Yes. I'm using the same initialization code that worked 2 months ago.

Ok, got it, pushing a new canary in a minute. It:

• Disabled wasm-opt, which was emitting mutable globals
• Pinned to Rust 1.43 on CI, I believe the rust compiler might have started emitting them on its own recently. Not that you should care, just for documenting this stuff.

I tweaked some things with the init code, not that different but altogether it will work once you npm install @citeproc-rs/wasm@canary again after that PR's merged. Here are my changes:

adomasven/zotero@citeproc-rs...cormacrelf:citeproc-rs

Ah, no, this hasn't done it.

[cormacrelf]

Confirm, that fixed it. That's ESR life I suppose. You should see the breaking JS API changes to string ids making things not work, that's how you know it's real this time.

My next thing is to avoid rustwasm/wasm-bindgen#1963 and hopefully make sure #78 doesn't rear its head with a custom JS Result type (i.e. a slightly annoying but overall fine .unwrap() after each API call), so there's a little more pain to go with that, but then you'll also get the improved init/locales/dependent styles/style metadata stuff I've been working on.
