Instance Method Details

#fabricate_with_tracing(_url, action_name, _options) ⇒ Object

Ethon::Easy doesn't expose the "action name" ('GET', 'POST', etc.) and Ethon's fabrication of HTTP classes uses Ethon::Easy::Http::Custom for non-standard actions. To be able to know the action name at #perform time, we set a new instance variable on the Ethon::Easy instance with the base name of the fabricated class, respecting the 'Custom' name where appropriate.

def fabricate_with_tracing(_url, action_name, _options)
  fabbed = yield
  instance_variable_set(ACTION_INSTANCE_VAR, NewRelic::Agent.base_name(fabbed.class.name).upcase)
  fabbed
end

#headers_equals_with_tracing(headers) ⇒ Object

Ethon::Easy uses Ethon::Easy::Header to set request headers on libcurl with #headers=. After they are set, they aren't easy to get at again except via FFI so set a new instance variable on the Ethon::Easy instance to store them in Ruby hash format.
