Could a byte stream read directly into and out of a SAB (w/o transfer)?

13

It would be really great if wasm could read from a stream directly into its memory. The backing `ArrayBuffer` of a `WebAssembly.Memory` cannot be detached (nor would you want to...

Supporting caller-allocated, callee-written buffer without views

7

For an API like the C standard library `read`: ``` ssize_t read(int fildes, void *buf, size_t nbyte); ``` where the caller allocates a buffer which the callee (partially) fills in,...

As discussed in #84, this PR adds an explicit result arity to the binary format. Thinking about this a bit more, it seemed like maybe we should have a symmetric...

"Lightweight Component Model" as new scope for layered linking + interface types spec?

12

This issue is for follow-on discussion of the [CG-04-27 presentation](https://docs.google.com/presentation/d/1PSC3Q5oFsJEaYyV5lNJvVgh-SNxhySWUqZ6puyojMi8) which was itself a follow-up proposal based on discussion in the [duplicate import issue (#1402)](https://github.com/WebAssembly/design/issues/1402). A high-level summary of the...

Disallow duplicate imports?

44

(This issue captures the [presentation](https://docs.google.com/presentation/d/1uq3uFkmXHRjP5V56wKlmxMH_gveYcigc8DIXYyGpWE4) at [CG-03-02](https://github.com/WebAssembly/meetings/blob/master/main/2021/CG-03-02.md), with the goal of getting more feedback in preparation for a poll at some future CG meeting.) The Module Linking proposal proposes to...

Measure size increase for enabling EH on modern C++ codebases

14

This is a request from people working on the producer side to get some real-world measurements of the size increase of enabling exception handling in large C++ codebases, particularly those...

Should producers/consumers assume throwing is "rare" and, if so, can the spec note this?

5

This is certainly the basic assumption for C++ but not for many other languages. The underlying question is whether engines can assume they can use the classic "zero-cost" EH strategy...

Remove "terminate" / describe uncaught exceptions

1

In the Overview, Throws and Debugging sections, an uncaught exception is described to *terminate* the application/execution/thread. Thus far, there is not a "terminate" concept in webassembly and, e.g., after a...

Add optional fixed length to lists

8

This PR adds fixed-length lists as a "gated feature" (i.e., features spec'd and ready to implement, but not yet included in a Preview release), as proposed and discussed in #181.

Consider defining an "instance reuse hint"

6

There's an interesting question and discussion in [wasi-http/#95](https://github.com/WebAssembly/wasi-http/issues/95) that, by the end, doesn't feel specific to "HTTP" at all and thus perhaps deserving of being addressed more generally in the...
