We actually discussed this in #rails-contrib earlier today. As it stands there are absolutely no locks or synchronisation in dependencies.rb, so it's completely thread-dangerous. There are a couple of things we could do: 1) Have a giant 'doing dependencies lock By wrapping a big lock around load_missing_constant and friends so only one thread goes about creating classes at any given time. All the other threads would have to wait for that lock to be released. This would probably be a little difficult to test, but not too difficult. 2) Have an alternative Dependencies mode. Just load everything up front before we start dispatching requests. Both these options were discussed in #9155 like tarmo said. Rather than Thread#exclusive we could use some specific mutexes so other threads can go about their other business. Any takers? -- Cheers Koz --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Core" group.
