Extending WebAssembly Beyond Supported Languages

[samyfodil]

Executing code that cannot be run on WebAssembly, either because it can't be compiled or using a compiled interpreter is not feasible or too restrictive, will be a powerful feature. This capability will also be beneficial for testing code generated by LLMs. The idea is to execute such code within a container.

Requirements

We need the following primitives:

1. Container Management:

   • Spin up and shut down a container.
   • Optionally, implement a way to make containers persistent or "sticky" for repeated use.

2. Code Handling:

   • Load code into the container.

3. Execution:

   • Execute the loaded code.

4. Output Retrieval:

   • Retrieve the output from the executed code.

Container Engine Selection

• Use Firecracker if the system is running on Linux.
• Use Docker if the system is not running on Linux.
