Is there something special I need to do to access session data in a worker? I''m using an AR session store. I''ve been working with Ezra''s tutorial, modifying it a little here and there to figure it out. So I changed the progress bar to a simple count-down in the worker which sends back the count to display in the view. No big deal. But if I try to access session

I have a very strange problem here. I do not get this. So any help is greatly appreciated. Basically I have a model that calls a method in the background process in the "after_save" method. Let''s call the model products. So what happens is this: 1. I create a new product. 2. Everything works and the product is saved with id 13. 3. A method is called in my background

I have noticed that occasionally (about 50% of the time) when i deploy (using capistrano) my app to a production server, i have to ssh into the box and manually stop and start backgroundrb to get it to load my workers. this is my basic setup i have 2 workers: lib/workers/mp3_worker.rb => takes a hash of params to downsample an mp3 lib/workers/flv_worker.rb => takes a has of

I''m just getting started wtih backgroundrb, and unfortunately hit a snag right away... I''m running the latest releases of rails, backgroundrb, slave and daemons. I created a simple worker class, using the generator, which currently does nothing but print the arguments that are passed to do_work. I''m running backgroundrb using ''./script/backgroundrb

I''ve been having a terrible time with the backgroundrb scheduler. The issues I''m having is that the scheduled actions aren''t ran at all and if they do, the process stays around forever. I''m using the backgroundrb as a nightly cron to run some accounting operations. questions: 1. How can I have the process destroyed after the worker completes? 2. Any idea on

First of all, I''d like to do what I''ve seen several others here do: thank Ezra and any other contributors for producing a really great plugin. Even though I''m having some minor problems, this is all so approachable and easy to work with and dig into... I hate to think of the hoops you''d need to jump through (both as creator of such a system and as a user) to

Hello Folks- I am really happy to announce the release of BackgrounDRb 0.2.0 . This is a complete rewrite and re-architecture of this codebase. I want to thank skaar for all of his hard work. I put out a call for help with the new architecture and skaar stepped up bigtime. I had already written the new scheduler and cron compatible syntax and moved to multi process architecture. But he

I''m using backgroundrb to periodically download a large file via ftp from a remote location and then import it into the database. To perform the import, I was using the following: ActiveRecord::Base.connection.execute(%{load data infile ...;}) although on a file with 2.5 million records, this can take 5 minutes, which seems to tie up my rails application while this executes (even

I have been strugging with getting backgroundrb to stay in the correct environment using multiple configuration files and the -c switch when starting backgroundrb. If I start brb like this: ./script/backgroundrb run RAILS_ENV=development -- -c ../config/development_background.yml where development_background.yml specifies "development" for rails_env and environment, the first worker

Hi there, I''ve been experimenting with implementing BackgroundDRb in my rails app but am running into some problems. The primary problem I''m getting is in cleaning up worker threads, or getting any kind of response out of worker threads. If try using the response function/hash in my Worker the worker will not execute reporting that response is an unknown variable or function.

Hello, Trying to get the example to work in standalone mode. I have the following in a file and am not certain why I get this undefined method error: error: ~/ruby sample_app.rb my sample app :) sample_app.rb:9: undefined method `new_worker'' for BackgrounDRb::MiddleMan:Class (NoMethodError) ### code follows ### # sample_app ... try to get stand-alone happiness. #require

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

Hello, I have some satellite tag time-at-depth (TAD) frequency data that I would like some help with. The data was transmitted via satellite as percent time spent in each of 7 depth bins (0m, 0-1m, 1-10m, 10-50m etc.), binned over 6-hour intervals. I categorized each row of data corresponding to a date and time into summer vs. winter, and day vs. night, and then summed and averaged the given

Devjavu''s svn is asking for a username and password. http://svn.devjavu.com/backgroundrb/ Authorization Required This server could not verify that you are authorized to access the document requested.

Hello, I''ve been trying to get the latest copy of BackgrounDRB as per the documentation here http://backgroundrb.rubyforge.org/. However, whenever I try to access http://svn.devjavu.com/backgroundrb/tags/release-0.2.1 I keep an authentication prompt and if I leave it blank I am declined access. Is there somewhere else to get the code or am I doing something wrong? Thanks, -carl --

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.

Hello, I''m currently using backgroundrb to fetch feeds for an RSS aggregator. So as you can imagine, backgroundrb is a very critical piece of the app. I was wondering what a recommended pool size would be for this kind of application. Ideally, I''d like to have as many processes in the pool as possible, but what would be too many? Thank you, David -------------- next part

Hey Guys, In the readme for Backgroundrb it says that windows support has been depcreated for this version, but then it goes on to mention how to use it in Windows. So I''m not sure if it should be running on windows or not, so I''ll ask anyway. Also, I''m new to ruby and I''m also new to server administration, so I apologize if my questions are pretty
