Surma (Feb 14 2023 at 17:58): Surma (Feb 14 2023 at 17:58):I just compiled wasmtime ToT with the wasi-threads feature to play with the WASI Threads module.
Trying to run a module fails with missing required memory export which is of course contradictory that threaded modules need to ahve a single memory _import_. Am I missing a trick? Or is it just too early?
Cheng Shao (Feb 14 2023 at 17:59):some special flags are needed, see https://bytecodealliance.zulipchat.com/#narrow/stream/206238-general/topic/.E2.9C.94.20Did.20anyone.20manage.20to.20run.20a.20wasm32-wasi-threads.20module.3F/near/326596161
Surma (Feb 14 2023 at 18:05):Ah none of those flags apply to me as I am not using WASI-SDK. I am writing raw WAT. BUT the key insight was to _both_ import _and_ export the memory. That made it work.
Andrew Brown (Feb 14 2023 at 18:52):Yeah, it's a Wasmtime-specific thing... hopefully improved in the future
Surma (Feb 15 2023 at 17:16):Wrote up a quick howto “WASI Threads with Wasmtime”: https://surma.dev/postits/wasi-threads/
Ralph (Feb 15 2023 at 17:51):I really liked this, @Surma
Ralph (Feb 15 2023 at 17:51):re-tooted, or whatever
Andrew Brown (Feb 15 2023 at 22:53):Welp... You'll want to take a look at the post I put together that is currently under review here (some BA group permissions needed, I think). Should be out next week and it goes into a bit more detail on the history of all this work.
Surma (Feb 16 2023 at 08:39):I hope i didn't steal any thunder!!! I'd love to take a look, but i have no clue how to get access.
Andrew Brown (Feb 16 2023 at 15:51):No worries!
