Build a Wasm execution abstraction that supports async host functions #2552
Comments

Hey @Twey , we actually support async host calls in the JS integration + asyncify. Happy to see what we can do to help you on the quest (feel free to email to: syrus@wasmer.io with more info) |

We actually can't remove this `Send` and `Sync` until we can send the `ExecutionStateRequest`s via `postMessage`, i.e. issue linera-io#2552. That issue is far enough divorced from this code that I don't want to link it here, so let's just remove the TODO.

* Update `linera-wasmer` to `4.4.0-linera.6` This version includes `JsValue` conversions for `Module` that include type hints. * `linera-execution`: add `JsValue` conversions for `wasm::Module` * `linera-execution`: preserve JsValue conversions in module traits * `linera-execution`: document `DynInto` * `linera-base`: adopt `dyn_convert` * `linera_base::task`: adopt `linera_execution::Post` * `linera_execution::wasm`: fix up comments * `linera-execution`: remove redundant TODO We actually can't remove this `Send` and `Sync` until we can send the `ExecutionStateRequest`s via `postMessage`, i.e. issue #2552.

In order to get the Web wallet working, we remove the ability to load Wasm modules from within async code, meaning we lose the ability to dynamically load applications during application execution. The root cause of this is that Wasmer doesn't (and thus our Wasm abstraction traits don't) support asynchronous calls, which is necessary to receive a
postMessagecall on the Web.In order to get this capability back, I suggest that we:
