calebschoepp opened PR #8384 from calebschoepp:trace-outbound-request to bytecodealliance:main:

This is to support tracing of outbound HTTP request in downstream libraries like Spin.

• Adds tracing to default_send_request that follows the OTel HTTP trace semantic conventions.
• Makes sure that the trace context is propagated across the async boundary introduced by the spawn.

I've not used #[instrument] myself before, but would it be possible to do something like url.full = request.uri() here in the macro instead of in the body below? I'm not sure if that has type restrictions on the return value of .ur(), but adding .to_string() may work well too.

Also, mind adding some comments as to what otel.kind, otel.name, and server.{address,port} are doing? The first two seem like sort of "standard variables" to set, but the second two aren't set here in the method either.

Sure, I'll look into that @alexcrichton. Also sorry, I force pushed a linting fix without realizing you'd already started reviewing this.

@alexcrichton is this something worth backporting to v18? It seems like this code changes a reasonable amount between v18 and v19.

It's possible yeah to backport to 18/19, yeah, but if it works it'd probably be best to get this in main and backport it to the 20.0.0 release happening this weekend and having Spin update to 20.0.0

Closing this b/c after a discussion with @alexcrichton we decided it is best to do this tracing in Spin. A subsequent PR will follow that will expose handler for Spin to use.
