Descripción

First off, my JavaScript environment is very custom and different than the web or Node.js. We are running in a wasm32-wasi environment with QuickJS, using wasmedge-quickjs, and Wasmtime on the Internet Computer.

That being said, the strange thing is that I had this working about a week ago, but now it doesn't work. We've been doing a lot of low-level changes to our JS environment (we're working at the engine/platform level), but I just don't understand what could have caused this.

The simple problem is that we get an error just trying to initialize the database: out of memory

Here's our code:

import { Server } from 'azle';
import express from 'express';
import initSqlJs from 'sql.js/dist/sql-asm.js';

export default Server(async () => {
    const SQL = await initSqlJs({
        locateFile: (filename) => `/dist/${filename}`
    });

    const db = new SQL.Database();

    const app = express();

    app.get('/', (req, res) => {
        res.send('Hello world');
    });

    return app.listen();
});

We have to use asm as our environment does not have a Wasm interpreter. I've tried sql-asm-memory-growth.js as well and I get the same error. I've even gone back multiple versions to maybe 1.7.0 and the error is always there.

Any ideas on what could cause this? I've also tried adding:

            TOTAL_STACK: 4_000_000_000,
            TOTAL_MEMORY: 4_000_000_000,
            FAST_MEMORY: 4_000_000_000

to the initSqlJs options.

Línea de trabajo

Start by reproducing initialization in the described wasm32-wasi environment, using sql-asm.js and then sql-asm-memory-growth.js. Trace initSqlJs through new SQL.Database() and compare the behavior across the mentioned versions and memory options. Done means identifying a reproducible cause or documenting the environment limitation and a confirmed workaround.
