How to rotate, override, or turn off logging from Sunspot Solr Rubygem?

Question

I\'ve had great experiences with Sunspot Solr search for Ruby on Rails, however, its log files are growing incredibly large and I can\'t seem to find a way to either rot

Answer 1

I've monkey patched the appropriate file in sunspot_solr to resolve this exact issue.

This code is not robust enough to survive rearchitecting/refactoring done directly in the sunspot_solr gem, so I recommend locking your sunspot_solr gem version to 1.3.0 for this to succeed.

You can drop the following into your project. We use it in a Rails project and have placed it at lib/sunspot/solr/server.rb:

module Sunspot
  module Solr
    class Server #:nodoc:

      def logging_config_path
        puts "# ==> Using monkey-patched Sunspot::Solr::Server#logging_config_path method"

        return @logging_config_path if defined?(@logging_config_path)
        @logging_config_path =
        if log_file
            logging_config = Tempfile.new('logging.properties')
            logging_config.puts("handlers = java.util.logging.FileHandler")
            logging_config.puts("java.util.logging.FileHandler.level = #{log_level.to_s.upcase}")
            logging_config.puts("java.util.logging.FileHandler.pattern = #{log_file}")
            logging_config.puts("java.util.logging.FileHandler.formatter = java.util.logging.SimpleFormatter")

            # >>> ADDED THE FOLLOWING TWO LINES FOR JAVA-BASED LOG ROTATION <<<
            logging_config.puts("java.util.logging.FileHandler.count = 7")
            logging_config.puts("java.util.logging.FileHandler.limit = 104857600") # 100 megs

            logging_config.flush
            logging_config.close
            logging_config.path
          end
        end


      end # class Server
    end # module Solr
  end # module Sunspot
