...cess 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, I''ve been able to do the same. My initial test worker runs fine as a non-RailsBase worker. Once I switch it to load rails as part of the worker, I run into a problem with fork, namely: Resource temporarily unavailable - fork(2) - (Errno::EAGAIN). My debug log statements within Middleman show that backgroundrb_results and backgroundrb_logger get loaded fine, but any rails worker d...

Hi, Can somebody point me in the right direction about what approach would be best to load-balance between two or more physical servers running backgroundrb while using BackgrounDRb::Worker::RailsBase with mongrel? Thanks, Robert Bjarnason

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) #<DRb::DRbUnknown:0x40691130> 20061120-21:54:28 (26296) /var/www/gorchie/release...

...nds 10, sleeps for a minute, sends 10 until done - very straightforward. My question is, what would be the best way to run this? I have assumed a cron like scheduled worker with a named key, but I don?t know. My worker looks like this: class EmailProcessorWorker < BackgrounDRb::Worker::RailsBase def do_work(args) queue = EmailQueue.new queue.process_queue end end EmailProcessorWorker.register I do all the work in a Rails Model, since I can unit test it outside of backgroundrb. Does anyone have a backgroundrb_schedules.yml file I could use as an example, and should...

Hi everyone, I''m new to backgroundrb, and I''m trying to get started with a simple example, yet with no success. This is the code that I have in RAILS_ROOT/lib/workers/testing_worker.rb class TestingWorker < BackgrounDRb::Worker::RailsBase def do_work(args) # This method is called in it''s own new thread when you # call new worker. args is set to :args logger.info(''TestingWorker do work'') results[:do_work_time] = Time.now_to_s results[:done_with_do_work] || = true end end...

I''m using the latest backgroundrb. Do I need to setup a worker in order to use it with Rails? I remember using "Worker::RailsBase" before. Also, how do I access the logger from within the worker? Thanks a lot! -- Lalo

...20070423-10:30:00 (29673) development database is not configured - (ActiveRecord::AdapterNotSpecified) In my database.yml file I have the production database setup as production: development to map the production database back to the development one. Unfortunately BackgrounDRb::Worker::RailsBase doesn''t know how to handle these types of database references. I also had a quick play with loading up irb and then requiring the config/boot.rb and config/ environment.rb files. Once I had done this I could access all my Rails models as I would expect. So I was wondering why the R...

Ok two things that bug me 1) http://backgroundrb.devjavu.com/projects/backgroundrb/ticket/48 i thought i''ll just post ticket link - but well - it''s strange 2) when i switch base class from RailsBase to Base i can''t access MiddleMan - i get error NameError: uninitialized constant MiddleMan from (drbunix:///tmp/backgroundrbunix_localhost_2999) (drbunix:///tmp/backgroundrb.8388/first_worker_30fe4904c2222fa80e54b58d587d7 bb0_0_0.446368947706132) /home/swistak/rails+backgrou...

Hi All, It might be lack of sleep, but I am struggling to accurately limit our pool size. It seems like I can specify it on the server with the -s command line option and also on the client via the YAML pool_size. Is that right? Which one wins? Our problem is that we are getting about 40 threads on each backgroundrb box and it''s flooring our db and each bgrb box. We want around 8.
