Refactor grate execution path and add grate test examples #472

Yaxuan-w · 2025-10-15T20:42:05Z

This PR refactors grate execution flow mentioned in issue #442.

Previously, the Wasm instance creation logic passed the closure directly to 3i, which then performed registration separately. In this PR, the closure is now passed as an argument to register_handler(), allowing 3i to perform both the registration and runtime binding internally.

This change:

simplifies the integration path and makes the 3i API adaptable to different runtime environments (e.g., Wasmtime, MPK, or future runtime backends).
removes closure usage in wasmtime <-> 3i

More details in code comments

Add grate tests examples as described in issue #468

This looks good from my first pass. I'm tagging Justin on this one since this probably needs his final review.

I really still don't understand the closure part, but the rest seems fine. I am about to get on a flight and so will follow up when I have time on that front.

JustinCappos · 2025-10-15T22:24:52Z

src/threei/src/threei.rs

-use sysdefs::constants::{
-    MAP_ANONYMOUS, MAP_PRIVATE, PAGESHIFT, PAGESIZE, PROT_EXEC, PROT_NONE, PROT_READ, PROT_WRITE,
-}; // Used in `copy_data_between_cages`
+use sysdefs::constants::{PROT_READ, PROT_WRITE}; // Used in `copy_data_between_cages`


This should likely be hidden with a helper function exposed by vmmap to tell you what you really want to know (whether a range is accessible).

I will say that I did think that putting a reference to the data you're putting in the closure in a table indexed by thread ID should remove the need for the closure, right? What am I missing?

putting a reference to the data you're putting in the closure in a table indexed by thread ID should remove the need for the closure

I think one possible solution is:

define a C-ABI callback in Wasmtime (essentially the same logic that’s now inside the closure) and store the required context on the heap;
pass both the function pointer and the context pointer to 3i;
let 3i look up the pid/tid, retrieve the function/context pointers, and invoke the function directly.

I’ll give this approach a try if that sounds reasonable.
