I blogged about some of the problems with aaf in production (http://www.jroller.com/BrightCandle) yesterday but inspired by the poitive response I thought I would share the perceived problems and discuss some of the potential solutions to help newcomers and make aaf work as if by magic just like Rails does. All of these problems boil down to one simple problem, running acts as ferret in a

We are close to releasing a high-volume, multi-lingual, e-commerce site in Ruby on Rails that has previously been written in an alternative Java framework (e.g. servlets and JSP). This is a real-time 24/7 betting and gaming web site based out of Gibraltar in Europe. When we embarked on this project, we really wanted to find examples of other high-volume web sites that had adopted RoR. We did

Just received the news from Tom Mornini. Congrats Ezra for the new Engine Yard site and the blog you will be collaborating.

Using the Drb allows me to synchronize writes to the index in a multi mongrel environment. I was under the impression that the remote index would not block if two mongrels were searching the index. Is that the case? This line in ferret_server.rb makes me think otherwise: # Calls are not queued atm, so this will block until the call returned. # def method_missing(name,

Hello, Yesterday I posted about how to email from a worker. I decided to be a bit piggy and just inhale all of rails. Sorted. I am noticing some rather ominous behavior though. The setup: My worker takes an uploaded image as a param and passes it (via system call) to a C++ image processing engine. Take a look at these memory consumption figures for successive runs uploading the identical image

so i have an after_create method on my track model that kicks off a background process that converts an mp3 to a swf. this is working fine locally on my machine, but upon moving it to my production server, i am getting the following error. I''ve only been using backgroundRB for like 48 hours, so i''m not really sure what this means or where to go. any ideas?

Jan, maybe I should check the /afs information that you pointed me at in a subsequent email first, but I wanted to update you on what happened following this path: I did get some mileage out of both of your suggestions below, but still did not make it through (now working with openssh-2.9p2): gcc -o ssh ssh.o sshconnect.o sshconnect1.o sshconnect2.o sshtty.o readconf.o clientloop.o -L.

Hi All, I''m using Backgroundrb as a general purpose long-running-task back-end (upload processing, email sending, etc), and it''s been a great solution. However I''ve recently run into some some intermittent connection issues that have me baffled. I''m running on apache2/fcgid and the problem occurs in both devlopment and production mode. The problem seems to

Hello, I am trying to make DRb calls to a external server from a backgrounDRb worker, but I''m getting always the next exception when I make the remote call. > ERROR: > drbunix:///tmp/backgroundrb.11175/experimenter_worker_3e899de945f0803a82cd257cfac316d0_0_0.0738904928422051 > - #<Errno::ENOENT: No such file or directory - >

Hey all, I need to launce a rather lengthy process from a small Rails application. It''s the sort of thing (sending out an email newsletter) that would need to be launched from a browser window, but the browser doesn''t need to stick around to see it through. I played around with Thread.new, but I think, based on limited testing, that the threads need to complete before the view

Hi, I have my Model as follows: class Mutation < ActiveRecord::Base acts_as_ferret ({:fields => {:description=>{}, :product_id=>{:index => :untokenized}, :product_description=>{}, :product_label_description=>{}, :product_label_free=>{}, :product_product_id_supplier=>{}, :product_description_supplier=>{}, :supplier_description=>{}, :pub_date_sort

I have a job that I am starting from a Rails controller in production mode using MiddleMan: MiddleMan.new_worker(:class => :import_ccg_category_worker, :args => { :category_id => @category.id, :remote_category_id => params[:remote_category_id], :description => "Importing CCG products for #{@ category.name}" }) Both of the category ID variables are just basic integers. I

hi, i am using drb and it is working fine on my local pc on windows.. and after uploading the code to the server it was working for sometime but now it gives me error every time i invoke the process.. error--- uninitialized constant EmailWorker::Notifier - (NameError) /usr/lib64/ruby/gems/1.8/gems/activesupport-1.4.2/lib/active_support/ dependencies.rb:477:in `const_missing''

Hi, all- I started playing with RSpec in a new Rails app. I''ve installed the plugin and bootstrapped it, and run ''script/rails_spec_runner'' (not rails_spec_server as the website currently reads, btw) in a separate shell, then in another shell I run ''script/rails_spec'' and get the following: /usr/local/lib/ruby/1.8/drb/drb.rb:837:in

I''ve run into a problem on one of my development machines. I''m trying to run multiple rails apps on one dev machine that runs Windows. Problem is that is seems that I can only run one scgi_service at a time, meaning that only one of my apps will function at a time. Anyone know how I can get around this, other than getting a *nix box (which I should have soon, hopefully) ?

Hi, I can''t get breakpointer to work on locomotive. Pretty sure it used to work... Any ideas?? Jeroen jeroen$ ruby script/breakpointer /Applications/Locomotive/Bundles/rails-1.0.0-max.bundle/Contents/Resources/ports/lib/ruby/1.8/drb/drb.rb:828:in `getaddrinfo'': getaddrinfo: No address associated with nodename (SocketError) from

Hey all, I''m having some issues moving a project that incorporates Backgroundrb onto a staging server... For some reason (surely of my own doing), my RailsBase workers are insisting on using trying to access my development DB instead of my "production" DB. When I try to load a model object from within a worker, I get the following: 20061120-21:54:28 (26296)

I am new to this list and relatively new to the backgroundrb plugin,. So first i will say hello to everybody here, especially to Ezra Zygmuntowicz! I played a little bit with a dummy worker and so far everything worked well. But now i want to do real work in a worker but now i get that error[1]. It looks like that the constants configured in environment* configs are not available to the worker

Hi, we still have the problem in that the Ferret Drb server dies on us sometimes. Looking through ferret_server.out and we come accross this: deadlock 0xb7261cb0: sleep:F(1012) - /usr/lib/ruby/1.8/drb/drb.rb:566 deadlock 0xb71d8654: sleep:F(409) - /usr/lib/ruby/1.8/drb/drb.rb:566 deadlock 0xb723f3e0: sleep:F(7) - /usr/lib/ruby/1.8/drb/drb.rb:566 deadlock 0xb72607c0: sleep:F(11) -

Hi everyone. I can''t get the above(subject line) combination to work. If I use a standard sqlite3 file db for the test db, and spec_server all the specs on my models pass. If I use an in-memory db for the test db, script/spec w/o spec_server, they all pass. But if I use in-memory and spec_server I get the following error: 1) ActiveRecord::StatementInvalid in ''User should be
