Let’s move forward with it.

Rename memory operations

Ben Smith

   * https://github.com/WebAssembly/spec/issues/627
   * https://github.com/WebAssembly/spec/pull/649 (short names)
   * https://github.com/WebAssembly/spec/pull/720 (long names)

Postponed

Annotation syntax for the text format

Andreas Rossberg

Provide generic notation to represent custom (section) information in text format

gist

POLL: We should create an annotations repo to hold a Phase 0 proposal to define annotation syntax for the text format.

Unanimous consent

AI: JF to create repo and tracking issue. Andreas to populate.

ES module integration

Lin Clark

   * https://github.com/WebAssembly/design/issues/1087
   * Discussion with webpack: https://github.com/webpack/webpack/issues/6433#issuecomment-363585102

SlidesSlides with presenter notes

  • Brad: how do we cope with deciding how a module is being loaded? MIME type?
  • Lin: yes. Byte-sniffing could also work.
  • Andreas: why cycling linking?
  • Lin: expect very close dependencies between JS and wasm. Acting as a wrapper. Also because ESM allows them, would be a stumbling block.
  • Andreas: difference with wasm and JS is types. Might paint us in corner.

POLL: create a stage 0 proposal for ESM integration, with Lin as champion.

Unanimous consent

AI: JF to create repo, link tracking issue. Lin to fill repo.

WebAssembly BigInt integration

Daniel Ehrenberg

   * https://github.com/WebAssembly/JS-BigInt-integration
   * https://github.com/WebAssembly/spec/pull/707
   * Where should this be in the process?
  • JavaScript has BigInt at stage 3. Shipping in Chrome soon. Being implemented for other browsers.
  • Have spec text.
  • Have some tests.
  • Michael: which stage is this in TC39?
  • JF: I’d be uncomfortable in moving to WebAssembly stable if it weren’t in stage 4 for TC39. I don’t think we’ll be in that position.
  • Dan: Note that other specs are making BigInt integrations already, e.g., HTML.

POLL: vote to move to stage 2.

Unanimous consent

AI: JF to update repo and tracking issue.

HTML serialization of WebAssembly.Module objects

Daniel Ehrenberg

   * https://github.com/WebAssembly/spec/pull/711
   * Where should this be in the process?
  • Only issue encountered was Brad’s PR disallowed posting to other agent clusters, e.g. service workers. Should we lift it?
  • Brad: was a restriction for SharedArrayBuffer. Trying to mimic.
  • Dan: you can’t serialize SAB though.
  • Brad: should be at least available in same places. No objection to having more.
  • Dan: previous spec also prevented IDB storage from HTTP, only allowed HTTPS.
  • Brad: I think for Chrome we’ll restrict this.
  • JF: I’d rather add restrictions in well thought-out manner, not ad-hoc.
  • Dan: this proposal was left out of the JS Web API specification by accident.
  • JF: not editorial change, so this affects first working draft.
  • Michael: we don’t do IDB at all right now.
