pop_frame(state, expected_frame, name, time, deduct_call_time_from_parent=true)

Pops a frame off the transaction stack - this updates the transaction sampler that we‘ve finished execution of a traced method.

expected_frame should be TracedMethodFrame from the corresponding push_frame call.

name will be applied to the generated transaction trace node.

push_frame(state, tag, time = Time.now.to_f)

Pushes a frame onto the transaction stack - this generates a Agent::Transaction::TraceNode at the end of transaction execution.

The generated node won‘t be named until pop_frame is called.

tag should be a Symbol, and is only for debugging purposes to identify this frame if the stack gets corrupted.
