feat: add span pointer attributes for websocket context propagation #15153

quinna-h · 2025-11-05T21:49:23Z

Description

Add span pointers to connect outgoing and incoming messages over websocket; adding attributes to the span links for websocket context propagation.

From RFC:

link.name | span-pointer-down (if outgoing) / span-pointer-up (if incoming)
dd.kind | span-pointer
ptr.kind | websocket
ptr.dir | d (if outgoing) / u (if incoming)
ptr.hash | S<128 bit hex handshake trace id><64 bit hex handshake parent id><32 bit hex counter> (if outgoing on server or incoming on client) / C<128 bit hex handshake trace id><64 bit hex handshake parent id><32 bit hex counter> (if outgoing on client or incoming on server)

Testing

See test_websocket_context_propagation generated snapshot file

websocket.receive parent and websocket.send / websocket.close
