W3 new store #2

webmaster128 · 2023-05-23T16:02:54Z

~~The CI failure will be fixed here: #1691~~ Done

maurolacy

Partial review. Will finish with imports.rs and instance.rs next.

+    // This mut be short living and not be used after the memory was grown.
+    pub fn memory<'a>(&self, store: &'a mut impl AsStoreMut) -> MemoryView<'a> {

+            .expect("Memory is not set. This is a bug in the lifecycle.")
+            .view(store)


Is this for performance or what? Just curious.

It creates a MemoryView as designed by the new Wasmer API:

/// A WebAssembly `memory` view. /// /// A memory view is used to read and write to the linear memory. /// /// After a memory is grown a view must not be used anymore. Views are /// created using the Memory.grow() method. #[derive(Debug)] pub struct MemoryView<'a>(pub(crate) memory_view_impl::MemoryView<'a>);

It seems like the Memory itself cannot be used directly:

#[derive(Debug, Clone, PartialEq)] pub struct Memory(pub(crate) memory_impl::Memory); impl Memory { // ... /// Creates a view into the memory that then allows for /// read and write pub fn view<'a>(&self, store: &'a impl AsStoreRef) -> MemoryView<'a> { MemoryView::new(self, store) } // ... }

Wonder from where these guys come from.

There seems to be some new Wasm extension here:

Guess this will have to be revisited soon?

Thanks for pointing this out. I sorted them now.

LGTM.

There are significant changes in the way memory and store are being handled in w3, with the FunctionEnv / FunctionEnvMut structs, which are above my head at this point.

+        let result = do_db_next(fe_mut.as_mut(), non_existent_id);


Like with clone(), seems some of these as_mut() can be removed. Not exactly sure which ones.

yeah, you are right. They create short living semi-clones.

LGTM

Since we don't load from memory cache anymore, the function's doc comment needs to be adjusted

Are these TODOs still relevant? The error handling looks to me, like it catches the same cases as before.

Thanks, I'll double check. I did not have the headspace to think about the error cases when trying to make everything compile.

nit: Not really related to this PR, but this could be shortened like this:

{

let mut compiler = Cranelift::default();

for middleware in middlewares {

compiler.push_middleware(middleware.clone());

}

compiler.push_middleware(deterministic);

compiler.into()

}

#[cfg(not(feature = "cranelift"))]

{

let mut compiler = Singlepass::default();

for middleware in middlewares {

compiler.push_middleware(middleware.clone());

}

compiler.push_middleware(deterministic);

compiler.push_middleware(metering);

compiler.into()

}

let mut compiler = Singlepass::default();

compiler.push_middleware(middleware.clone());

}

compiler.push_middleware(deterministic);

and same in make_compile_time_store

oh, right. This was different when the code was originally written.
