Can memory be limited?

[huntc]

Is there a means of limiting the amount of memory that a wasm app can use when invoked via wasmi?

If not, is there interest in such a feature?

My rationale is that I am looking to run "untrusted" code, hence wasm given its container-style properties. Relying on the 4GiB limit of WASM itself would not work well for resource-constrained target environments.

Actually, I've just discovered a way. Perhaps this will be useful for others...

For completeness, another suggestion cited here: https://users.rust-lang.org/t/how-to-set-max-memory-limit-in-wasm/64725/10

The flags can also be declared in a .cargo/config.toml file so that a regular cargo build --target=wasm32-wasi command can be used:

[target.wasm32-wasi]
rustflags = ["-Clink-args=--initial-memory=2621440 --max-memory=2621440"]

The above will limit memory allocations to 40 pages.

The same question was just asked very recently: #720

I'm going to close this given the discussion at #720. Thanks.
