TPAC

Should we meet at TPAC 22 - 26 October 2018 in Lyon, France

Yes, let’s do one day with the Working Group and invite CG members and other groups.

AI: JF to privately reply to Coralie's email about this.

HTML serialization of WebAssembly.Module objects

Daniel Ehrenberg

Punt to next meeting

Rename memory instructions

Ben Smith

Concern about “mem” versus “memory”, consistency, how descriptive, etc. Not very common opcodes. We might later add fill / zero / copy. Other instructions are already longer, and so are the section names.

Unanimous consensus to go with “memory”.

Mutable Globals proposal update

Ben Smith

Now in beta Firefox, no bug report from users. Some issue with Emscripten with globals not being enumerable, when doing dynamic linking. Could add toJSON in the future.

Ben to work on mutable globals soon.

Sign-extension operators proposal

Ben Smith

  • Implementations status?

Chrome implementation behind a flag. Also in Firefox in Nightly. There are tests in the proposal repo. Would be nice to have Emscripten implementation for just sign-extension (without threads). Could probably move to the next phase.

Subcommitees? - Discussion

Brad Nelson

  • Would CG subcommitees be useful for some topics like:

    • Exceptions
    • ES6 Modules
    • CSP

  • Do we need anything formal or would informal work?

We’re getting bigger features. Would it make sense to have optional CG meetings for people interested in these particular topics?

AI: JF to check with W3C what the process is, CC Brad and Eric Prud'hommeaux.

Do we want mailing lists? How do we organize? GitHub issues? Video chats? Sub-group chair (should those be the champions)? How do we establish charter for sub-groups? Notes, timing, other requirements?
