elliottt opened PR #7366 from elliottt:trevor/request-ids-serve to bytecodealliance:main:

Add some missing log handling to wasmtime serve:

• Log the listening address and port before starting to accept incoming connections
• Track individual requests with unique ids
• Prefix stdout and stderr from the guest with the request id

It's not clear that there's a reasonable implementation for this here. Perhaps using tokio::io::Stdout instead of a mutex guarded std::io::Stdout would make more sense?

I think it would be reasonable to make a separate Stderr handle here. My thought was that since the output is already prefixed with stdout/stderr, using the same output stream would be okay.

Looks good to me! One thought about whether or not this should be an async write, but otherwise seems fine to me

What would you think of going ahead and directly doing a blocking write to stdout/stderr here? That'd help applying a bit of backpressure (albeit not in a perfect way) if necessary and additionally would avoid the need to pass around streams much. That'd also perhaps make it a bit easier to write stdout to stdout and stderr to stderr.

Great suggestion! I've implemented that, and substantially simplified the LogStream::write implementation :)
