Hey :) I''m trying to create a method for making a sitemap dynamically. It works great for flat sites where you simply have your controllers in the app/controllers directory. In this case, I can extract the controller names like, @controllers ObjectSpace.subclasses_of(ActionController::Base).each do |obj| @controllers["#{obj.controller_name}"] = obj end However, now I''ve divided the site into modules, that is, I have for instance both Store::ItemsController and Manage::ItemsController, which reside in app/controllers/st...

...more as mysql socket are not closed In my humble opinion there are two reasons for it: - ActiveRecord::Base.allow_concurrency = true That will make every thread open it''s own socket to mysql - Mysql adapter implementations (RAILS or gems) that close connection on Garbage connexion (using ObjectSpace.define_finalizer ) There is probably a memory leak on connections as the Proc finalizer is not be executed when worker thread is killed (= connections are not GC). In this case the only way to release the sockets is to close the backgroundrb daemon. Those two phenomenons lead to an accumula...

Hi! I want to do what subject say. Is there any elegant way to do this: ??? # Silence the log inside the block attached to the method call. def silence_logger orig= nil ObjectSpace.each_object(::Logger) do |logger| logger.info "-" * 80 logger.info "Quieting the log..." orig= logger.level logger.level= ::Logger::FATAL end yield ObjectSpace.each_object(::Logger) do |logger| logger.level= orig logger.info "Log is alive ag...

Howdy -- I''ve been tracking down mem leaks (oh, the fun...), and I think there is a clue in objects.log. There are a few mentions of this file, but usually Zed saying "look at this file and it will help you". Can anyone clue me in to what the actual columns mean? 18,Float,143952,256821,112869,,, 18,String,39543,41693,2150,24.727076,55.526376,2308.000000

Anyone know a pretty way to get a list of all Models? That is, a list of all classes which inherit from ActiveRecord:Base I can''t seem to figure it out! The best I''ve got is to list the /app/models directory... but, that is *dirty*. -hampton. -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi all, Here''s my initial stab at a pure Ruby win32-thread library that doesn''t work at all. I''m not sure how to pass the start address of the arguments to the callback. I thought about Marshal, but you can''t marshal a proc. BTW, the CreateThread method in windows-pr needs to be updated for this to have any hope of success. Any ideas? Thanks, Dan #

Hi, I''m using an ActiveRecord::Observer to log users changing data in my application. However, I''ve noted that adding an item to a has_many relationship gets logged, but removing the item does not. That is: @product.users << user is logged, but: @product.users.delete(user) is not. I''ve dug into ActiveRecord and found that the underlying issue is that the

ActiveSupport provides a method Object.subclasses_of, shown below: def subclasses_of(*superclasses) subclasses = [] ObjectSpace.each_object(Class) do |k| next if (k.ancestors & superclasses).empty? || superclasses.include?(k) || k.to_s.include?("::") || subclasses.include?(k) subclasses << k end subclasses end Can anyone shine some light on why it (very deliberately) doesn't...

Hello, I''ve been working for a few days on a problem which, after tracking it down, seems to be related to unicorn. I''m hoping that somebody might be able to help with information about what''s going on. In the Rails 3 application that I support, we sometimes fork during a web request in order to do background processing behind the scenes without the user (and the

Heya guys, This one is bothering me as its evading my eye. I''m trying to set a callback on finalization of an object, ie: a finalizer set through a plugin to the model. Example In Plugin: def acts_as_goat class_eval do ObjectSpace.define_finalizer(self, Proc.new {self.conn.close} ) end end class UberGoat < ActiveRecord::Base acts_as_goat end Anyways, it seems to not be calling the finalizer? Is this the correct way to set a finalizer or am I going about it the wrong way. I need to close a socket connection _af...

Hello. I have an application that depends on a table/model (ModelInternationalization) that provides international translations in various languages for all the model/table and columns names as well as some other stuff (whether the column is visible on forms, dropdowns, lists, reports etc). I need to create a management interface for this translation stuff (the plaintext stuff, btw, will be

...he subscribers list. When an event is broadcast, its "notify" method is called, it gives a "pure virtual method call" error (wxruby 0.6.0).

Hi I''ve migrated from Passenger to Unicorn about a week ago. It''s great. Great transparency and management, thanks for this great software! A few of my Rails applications start background jobs using Kernel#fork. Of course, the ActiveRecord connections are closed and reopened again in the parent and child processes. The child process also does its job. Unfortunately, it seems
