similar to: problem with backgroundrb

I''m using backgroundrb for session management and deletion of visitor-entered information when a session is abandoned. The visitor can either click a button to end their session and remove their data, or backgroundrb will do it for them after 5 minutes of inactivity. Everything''s working fine, I think. If the visitor explicitly logs out, then when the worker checks for their

In response to my Rails Weenie post today[1], someone mentioned that I try BackgrounDRb to help take the strain off my application. 1: http://rails.techno-weenie.net/question/2006/7/13/nested-loops- best-way-to-send-messages-to-blog-subscribers I''ve just tried to install and use BackgrounDRb with my app, but I''m afraid that I''m not too versed in running processes

Is there a convention for handling exceptions within BackgrounDRb workers? For example, I have a worker which does some asynchronous data processing (*not* a scheduled worker) based on some things in the database. However, if an exception is raised within that worker, then the process for that worker is killed off. Ideally I would want that worker to just silently fail and be optimistic that it

Hello all. I am using BackgrounDRB with "great happiness and joy", however, I am running into one problem in that when I am running my tests with autotest using Sqlite3 3.3.17 I am getting "ActiveRecord::StatementInvalid" exception inside of the sqlite_adapter.rb:360 which is checking for an empty structure. I thought it might be the version of Sqlite, so I upgraded to 3.3.17

In my worker class, when i try to start the worker thread, it throws the error: uninitialized constant LoginEngine - (NameError) /usr/lib/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active_support/dependencies.rb:123:in `const_missing'' /usr/lib/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active_support/dependencies.rb:131:in `const_missing''

Hello all, I am importing large word documents. I have a test file which is 30mb in length. I run this through a series of processes to clean it up and extract the data i need to inject bits of it into a database. The 30mb file runs fine on my Mac. But on the FreeBSD server dies with a NoMemoryError at one of the first steps, which is normalizing the file. Basically, the sequence is the user

Hello, I''m trying to send emails from a backgroundrb worker and the email doesn''t send. I get no log messages in the sendmail log or the system log, nothing in the backgroundrb logs at all, nothing in the production log. Below is my code for each component worker: class QuizReviewerWorker < BackgrounDRb::MetaWorker set_worker_name :quiz_review_sender def create(args =

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 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

I just had an interesting issue on a production system that has been running nicely for about a year. There were approximately 10,000 backgroundrb temp files in the /tmp directory. It looks like backgroundrb wasn''t cleaning them up. I noticed it with the following error: DRb::DRbConnError: drbunix:///tmp/backgroundrb.20015/ backgroundrb_logger_0_0.101544829808665 -

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

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)

Hi all I''m experiencing something strange with a :job_key, it took me a very long time to find out a worker wasn''t doing it''s job because of the name of my job_key. The first one I tried was :make_kohier, and with that name (and lot''s of other ones) I can''t get the worker to work. I do get my key in return, but the job doesn''t start

Hi, First off, thanks Ezra for showing the way with BackgrounDrb. It''s a real godsend. I wanted to add a bit of job control to the system so that I could cancel DRB processes and so on. I thought I''d share how I did it in case anyone should find it useful or have feedback. I wanted to be able to put checkpoints into the drb job so that I could let the job do whatever needs to

Hello all, After upgrading to Rails 1.2.2, I''m getting a strange error when one of my workers is invoked. The worker is responsible for monitoring a folder (using directory_watcher) and emailing a specific user when a file is dropped there, but it''s bombing immediately upon instantiation (or maybe when trying to instantiate ActionMailer?) with the error "Text is not a

Hi, I''m not much of a developer but I''ve been using backgroundrb for a while now and with the release of 0.2.1 it looks like I can finally upgrade from the old version (0.2.0 had some weird issues when jobs just wouldn''t run, seems to have cleared up now - Thanks!). Anyhow, while I''m doing this, I would like to tackle this problem. Most tasks I run in

I want to use DRb within my Rails app. Right now I''ve got a very basic class: class PaymentGateway cattr_accessor :ssl_config, :host, :port def self.gateway @@gateway ||= new end def process(amount, card, type = :auth) @biller.process(amount, card, type) end def set_card(user_id, number) @biller.set_card(user_id, number) end protected def initialize

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 - >

Hi Ezra, Thanks for the great work on BackgrounDRb. I have come across a couple of problems. 1. I wanted to define a simple class in the worker file to wrap up and pass back some data to my controller. It seems that if I create the class either inside or outside of my worker class (in the same file) it gets wrapper by a DRb::DRbUknown object and therefore cannot be accessed from my controller.
