gc times increase linearly over time
It's somewhat expected behavior, since we don't do generational gc yet and is based on a naive copying gc implementation for now, so gc time (when it actually happens) is dependent on heap resident data size
Hiya friends, I've been taking a look at Asterius and am really amazed by how well everything already works! I'm currently trying to attach event listeners, but am running into some trouble:
This is my foreign import, and this is the wrapper I make around it:
addEventListener :: DOMNode -> String -> (JSVal -> IO ()) -> IO () addEventListener node eventName _callback = do -- Temporary, just trying to get *something* out of Haskell cb <- makeHaskellCallback (putStrLn "Got callback") ffi_addEventListener (coerce node) (toJSString eventName) cb
Unfortunately, I never end up getting anything back...
Whenever I change the ffi import to
I do in fact get a console message, but it's a Promise that has already resolved by then. Does this have something to do with laziness?

Hello! I used

RuntimeError: returnFFIPromise: unsupported thread stopping reason 0-- which looks to my untrained eye like a normal thread stopping point: success. The relevant somewhat minimal reproducible code is is at https://gist.github.com/christianlavoie/db264f799ef10638d102259e10d188f4 and https://gist.github.com/christianlavoie/06254660f118fb718909f448ff1273d5. Thoughts?
Trying to cross compile a library to wasm. During the
