Rails Ruby on Rails → 2.x

description

benchmark DB time, rails only considered the default DB connection(in multiple DB situation).

details

check http://github.com/rails/rails/tr... line 55, 101

it only picked the run timing of the default DB connection:

ActionRecord::Base.connection.reset_runtime

thus, any other connections(i.e. connection to my reporting DB) is wrongly ignored. the result is: in production.log, you will see Rendering time nearly 100%, while DB time 0%.

solution

define ActiveRecord::Base::reset_db_runtime

def self.reset_db_runtime

  timing = 0
  self.active_connections.each_value do |conn|
    timing += conn.reset_runtime
  end
  timing

end

replace every call in benchmarking.rb ActiveRecord::Base.connection.reset_runtime to ActiveRecord::Base.reset_db_runtime

I am using rails-1.2.3, but it seems the latest code still have the issue.
