I’m trying to explore and use your FaaSM project to do some research work. But I met some troubles, which I spent some time on it but not work.

First, How to access shared files in Serverless function, e.g, I upload a file by “ curl -X put -H “FilePath: test.txt” localhost:8002/file -T test.txt “. How can I access test.txt in Serverless function? I tried to invoke shared_file, which is a demo function, with a input-data “test.txt”. But it did not work.

Second, How to immediately update the function has beed uploaded? For example, I rewrite a Serverless function, and upload it to run. But sometimes, older function is revoked rather the one just re-compiled and uploaded. And "inv func.flush” does not work.

Examples of uploading, modifying, flushing and invoking a function can be found on the C++ function page.
