Hi! As you might remember I''m having a problem of backgroundrb stopping calling my workers after some period of time. I tried adding logging to backgroundrb source code but it didn''t help. So, after digging through internet I''ve found several gdb tools and here''s what I''ve discovered: After attaching to a backgroundrb ruby process it turns out that it

Hi all, I found this thread in the August backgroundrb-devel archives. >This means that in order to reference the new_worker method *in the >instance that is running in the drb server* you can''t do that >directly. In order to spawn other workers from within a worker I >would have to change the MiddleMan class to be a singleton. This way >you could grab the one instance of

got a wierd problem maybe someone can help with. whenever i try to pass an array or AR objects to my worker, i end up with a DRb object in the worker...here''s an example class SearchWorker < BackgrounDRb::Rails attr_reader :resources def do_work(resources) logger.info resources.inspect end end class SearchController < ApplicationController def start_search

Hey there bdrb''ers! I have been so very busy with http://engineyard.com that I have not had time to complete the new release of backgroundrb. But I have done substantial work towards it. It is basically an entirely new beast with a complete rethinking of how it works. I have put up a zip file of the new code base in the hopes that some folks will be able to start playing with

Hi Has anyone mocked a call like the following for backgroundrb? MiddleMan.new_worker(:class => :admin_email_worker, :args => params [:email]) I cannot seem to find the correct manner to do it. Would have liked to be able to do MiddleMan.should_receive (:new_worker).with(:class => :admin_email_worker, :args => {"body" => "my message"}) Cheers Shane

Hi list, I''m having some issues getting backgroundrb to play nice with more than one mongrel. When I run my app on a single mongrel instance it works fine. I have two different problems show up in my backgrounrb_server.log. The top of the backtrace is shown here: 20070130-12:03:03 (92473) failed to find slave socket - (RuntimeError) 20070130-12:03:03 (92473)

Friends- I''m happy to annouce the first alpa release of BackgrounDRb. This is a small framework for managing long running background tasks that allows for ajax progress bars and more. It also serves as an Application wide cache and context store for when you need something like sessions but shared between users and multiple backend processes like fcgi''s or mongrels.

(Sorry my last email had the wrong subject) Hi, I''ve just installed background rb 0.2.1. When I try start a worker in my application controller I receive the following error: wrong number of arguments (2 for 1) - (ArgumentError) /home/chris/projects/call_manager/trunk/call_manager_app/vendor/plugins/backgroundrb/server/lib/backgroundrb/middleman.rb:211:in `initialize''

for some strange reason this error occours when i create one worker from another BUT only when i derive worker class from Worker::Base instead or Worker::RailsBase - when change it back it works fine, child worker can have empty do_work, but this error still ocours Bad file descriptor (Errno::EBADF) /var/lib/gems/1.8/gems/slave-1.2.0/lib/slave.rb:214:in `for_fd''

Hello all, We''re currently running version .1.x in our environment. We would like to move to .2.x to take advantage of some of the improvements made running in a multi-process environment. We deploy to a linux environment but develop locally in Windows. I''m aware that a number of people have reported the ability to run .2.x of backgroundrb inside cygwin, and for the most part,

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

Hi All, Real neophyte here, to both backgroundrb and ruby/rails in general. (Hey, we''ve all got to start somewhere, right!) :) I''ve just been playing around with the example code at http://backgroundrb.rubyforge.org/ , and trying to get all the pieces to work (btw, I''m using version 0.2.1). I did a ''generate worker example'', which created an

Hello all, I''m having some trouble getting backgroundrb set up so that all the processing happens on a single machine. I have 3 load balanced machines. Right now, all three run our web application and create MiddleMan workers to generate a large PDF report. However, because of the processing power needed to generate the PDFs, I want to change our setup so that two servers run

Hello, We are working on a centralized report generating project, which calls for data processing on different servers and then centralizes the reports into a single project. What we would like to do is have a Monitor BackgrounDRb worker call another BackgrounDRb worker to process data on a different server, and then have our Monitor Worker collect the data and then store it according to our

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, Does it make sense to test a worker class by calling Middleman.new_worker? Or should I just be testing the functionality in the do_work method, with, say, a mock object. This seems like a really ugly DRY violation: you''d need to keep the code in the mock and the real worker in sync. That''s the philosophical half of my question. In fact, until someone tells me why I

Hey, I have scheduled script that is not working very well. It will only run once or twice before I have to restart the server to get it running again. If I try to the worker manually after it has stopped exceuting the schedule I get this in the server log: 20070522-07:33:36 (5030) Connection reset by peer - (DRb::DRbConnError) 20070522-07:33:36 (5030) /usr/local/lib/ruby/1.8/drb/drb.rb:566:in

I''ve been checking out all the async gems and plugins for Rails, and decided to give BackgroundRb a shot. Unfortunately, I''ve not even been able to get past the initial stages. Whenever I call MiddleMan.new_worker, it invariably returns nil. The log file remains empty. I''ve only tried this from the console so far. If I can''t even do this successfully,

I''m at a loss to explain a very strange error I''m getting. This seems to happen on our production system where we have a backgroundrb server sharing a host with a Rails app running on Mongrel. The first one or two, occasionally three, calls to a worker (direct MiddleMan calls from Rails, not scheduled) succeed, but afterwards, the server fails to initialize new workers.

Hello - Can anyone explain why I get the stack trace in background_server.log when I try to start my first worker? I don''t get this on subsequent workers, only the first one. I should note, the method I am using to start backgroundrb is documented in the archives, and is likely the root of this problem. Suggestions about how to "fix" or avoid this issue are appreciated.
