Instrumentation feature not working #505
Description
The new instrumentation feature (#499) does not seem to work, using the simplest example case.
It expects an instrumenter object which responds to instrument, start, and stop:
http/lib/http/features/instrumentation.rb
Lines 24 to 25 in 4bc1223
which means we have to pass
ActiveSupport::Notifications.instrumenter (which differs from the documented example).
But when I try to make a request, it appears to fail when I chain a get request:
2.5.1 :002 > require 'http'
=> true
2.5.1 :003 > require 'active_support/notifications'
=> true
2.5.1 :004 > HTTP.use(instrumentation: {instrumenter: ActiveSupport::Notifications.instrumenter}).get("https://httpbin.org/get")
