I have installed backgroundrb. I can start it. I have read everything I can get my hands on, and have read the list for a few months. I have written a worker, and am ready to start. This worker reads a queue, and processes it (sends queued emails). Sends 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

We have a fairly expensive task that we''d rather not schedule too many instances of in parallel. Couldn''t get pool_size to limit the amount of workers, and I figure that''s hardly optimal anyway, so would like to have the work queued up for a single named worker instead, running as soon as possible. Using MiddleMan.schedule_worker() with :job_key does start off a

I''m running the latest backgroundrb mainly for scheduled tasks support. As per the documentation I created the backgroundrb_schedules.yml with the following: simple_label: :class: :document_sorter_worker :worker_method: :do_work :job: :bleh :trigger_args: :start: <%= Time.now + 5.seconds %> :end: <%= Time.now + 10.minutes :repeat_interval: 1.minute Under

Hi, I''m using backgroundrb but I have 2 problems with it. First is when I launch a thread Toto from the do_work method. Toto can''t access to a class variable defined before... (undefined method `+'' for nil:NilClass) I suspect that thread is launched when backgroundrb start but the worker not .. My code is : class MonWorker < BackgrounDRb::Worker::RailsBase

I''m having a little difficulty understanding how to retrieve results from deceased workers (from the documentation it seems that it is possible to do this). I pasted my simple test below. If anyone could point out what i should be doing differently i''d be very grateful. My test worker: class TestWorker < BackgrounDRb::Worker::RailsBase def do_work(args)

While debugging stale backgroundrb it became apparent that there''re memory leaks in it. Here''s top object counts dump: 36715 String 6211 Array 5598 Proc 3150 Hash 1478 DRb::DRbObject 1313 Regexp 1272 Class 750 Thread 741 Socket 739 Slave 739 Slave::LifeLine 737 Process::Status 691 DrillReminderWorker 391 Module 160 Range 75 Gem::Version

Hi everyone, I''ve a class that try to spawn two workers, every 5 seconds. The code is something like: while true do MiddleMan.new_worker(:class => :researches_worker,:job_key => :researches) MiddleMan.new_worker(:class => :products_worker,:job_key => :products) sleep(5) end I''m using ":job_key", so if a worker hasn''t already ended its work

Hey all, I''ve come accross BackgrounDRb and I have to say it''s a wounderful piece of software. It has the potential to solve so many of the problems that I am facing with a current RoR project. Like many others I was having issues with the scheduling side of things, I noticed that hemant said there was a new version coming out. So I checked out the version from trunk, and have

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''

Hi , How do i schedule a job that can send emails at intervals of time using backgroundrb and rails For testing When i hit the controller i''m able send the emails. but that is not i intend to do ..... I want to use backgroundrb and rails in which i''ll schedule a job for every 5 minutes/ 1 minute or so..... to send an email But when i write

Hi! I''ve just a created a really simple rails scheduled worker for backgroundrb to start playing with : class SessionCleanerWorker < BackgrounDRb::Worker::RailsBase def do_work(args) logger.info "SessionCleaner> started" CGI::Session::ActiveRecordStore::Session.destroy_all( [''updated_at <?'', 120.minutes.ago] )

Hi all, I''m a newbie to backgroundrb and am having trouble integrating it into my rails-app. I''m using namespaces to differentiate between the parts of my app. When I want to create a new worker, it seems that it cannot find the worker object. Here''s my code: -------------------- controller app/passwd/index -------------------- class Passwd::IndexController <

I''ve been trying unsuccessfully for the better part of today to write a worker that can use by ActiveRecord model classes. The bizarre thing is that worker just stops at the point accessing the database connection. An exception isn''t raising, it just dies. My worker class is below, I''ve interspersed log messages throughout to try to determine where it is dying. =====

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

I figured out that in the backgroundrb.yml, I had the old setting of making the database RAILS_ENV. It wasn''t a valid variable in backgroundrb 0.2.1, and it wasn''t reporting an error, so I had no idea. Once I changed it to ''development'' or ''production'', it started working. I found that if a worker has an error, it usually logs the error

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! I have been using backgroundrb for a small project. My worker task is run every minute, checks the processing queue in data-base and execute the business method from Rails if something is to be done. Unfortunately I was hit by the problem of backgroundrb server dying after some runs. The exception is: 20070531-11:06:05 (31816) Starting worker: s_e_work sql_exe (s_e_work_sql_exe) ()

Looks like my first question a couple of days ago wasn?t very clever asked, at least very sucessfull.... So, anyway...i will try it again: I have to prefix that I am far away from fully understanding the overall concept yet, and there?s no way to get some hints in the www so far, at least my resaerches dont lead to any helpfull stuff. image_controller.rb: def create MiddleMan.new_worker

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)
