similar to: BackgrounDRb 1.0 pre-release available now

Hi Folks, I am glad to announce 1.0 release of BackgrounDRb. This would be a major release since 0.2 release of BackgrounDRb. Here is a brief summary of changes: - BackgrounDRb is DRb no longer. It makes use of EventDriven network programming library packet ( http://packet.googlecode.com ). - Since we moved to packet, many nasty thread issues, result hash corruption issues are totally

I use BDRb to process RSS feeds for users on my site (http://feedflix.com). I have a batch job that queries the DB for records that haven''t been updated in the last so many hours and kicks off a background job for each of them. If N records are returned by the DB, N background jobs gets queued and get done serially. As long as N is 255 or under, everything works like a charm.

Hello ! 1) I have this error logged by bdrb: undefined method `send_request'' for nil:NilClass framework/packet_master.rb:58:in `ask_worker'' backgroundrb/server/master_worker.rb:59:in `process_work'' backgroundrb/server/master_worker.rb:16:in `receive_data'' backgroundrb/framework/bin_parser.rb:29:in `call'' backgroundrb/framework/bin_parser.rb:29:in

Hi, I am using backgroundrb to process audio files from a rails controller. Currently a new worker gets created every time the method is called on the worker, using this code: @job_key = MiddleMan.new_worker(:worker => :audio_file_worker, :job_key => Time.now.to_i) MiddleMan.worker(:audio_file_worker, @job_key).make_new_audio_file(params[:release_id]) I need to create the new

Hi, i''m going to implement a syndication-service, which will get lists in xml with some meta-data an enclosed video files, which will get encoded at the end. The syndication run will be startet every five minutes of a full hour. So i thought to build 4 Worker. One for checking which feeds to syndicate (syndication_worker) at a specific time, one for processing the list

I''m trying to run a single worker that could perform a periodic task for a given user. >From a controller, I imagine something like: def start_job MiddleMan.ask_work(:worker => :foo_worker, :worker_method => :perform_task, :data => { :user_id = current_user.id }) end def check_job @status = MiddleMan.ask_status(:worker => :foo_worker)[current_user.id] end

Hi, A pre-release version of backgroundrb is available now from svn. Download it from here: http://svn.devjavu.com/backgroundrb/branches/version099/ Since this release marks significant migration from existing practices, i intend to keep trunk untouched for a while. There are no install scripts, but you should copy "backgroundrb" file from script directory of plugin to script

Hi Folks, BackgrounDRb is a Ruby job server and scheduler. Its main intent is to be used with Ruby on Rails applications for offloading long-running tasks. Since a Rails application blocks while serving a request it is best to move long-running tasks off into a background process that is divorced from http request/response cycle. This new release of BackgrounDRb is also modular and can be used

I''m using a plugin which adds a method to ActiveRecord::Base http://similetimelinerailshelper.googlecode.com/svn/trunk/simile_timeline/ This adds an "acts_as" type declaration to the Models, via the file in vendor/plugins/simile_timeline/lib/simile_timeline.rb Rails is working with these declarations, and they are being used successfully in ''regular

After some initial stumblings, I think I''ve got the hang of backgroundrb. It''s great! I''d been thinking for many many months how cool something like this would be! I''m trying to make a "job queue". That is, a pool of worker threads monitor a queue. When a job appears, one of the workers grabs it and executes the task. When complete, the worker

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

I have a question on how multiple b/g processes that are kicked off get handled in terms of sequence/schedule. On my site, a user enters an RSS feed to be processed and since this takes about 5-10 secs, I pass the process off to a background job and meanwhile do some Ajaxy spinners and tap-dancing until the job completes and then redirect_to the appropriate page. This works great. I also need to

I recently switched over to v1.0, and things are rolling along pretty well. However, one thing that has always been a little confusing to me is knowing when to use thread_pool. Since most of my bgrb workers are called from my web app to process rather than being scheduled, I''m using the thread_pool for every call. Unfortunately, that means that I have to split up workers by how many

Hey all, Been reading through all the old posts (and the docs) to familiarize myself but I still feel a bit lost. I''m on trunk and am having a bit of a hard time knowing where to start with the particular I''m trying to solve. So far, I''ve downloaded backgroundrb, done the basic rails setup, created my worker and started it using `script/backgroundrb start`.

What does the method query_all_workers() do? There is no documentation on what this method returns (1.0.1 version). Orion -------------- next part -------------- An HTML attachment was scrubbed... URL: http://rubyforge.org/pipermail/backgroundrb-devel/attachments/20080118/9f9b8112/attachment.html

Hey All, I am looking for an example of the proper config settings for background rb to run my rails app and my backgroundrb instance on separate machines (or more precisely, to have a rails cluster with one backgroundrb machine). Does anyone have such examples? Thanks! -Noah -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi Folks, Well, Yesterday I pushed some more updates that I was cooking since last couple of days. Here is a brief list: 1. Results from worker stays even after a worker dies. 2. You can ask backgroundrb to store status objects in memcache cluster now. by default its stored in master process memory, but I have introduced an option to allow it to be stored in a memcache cluster:

Forgive me if this has been addressed somewhere, but I have searched and can''t come up with anything. I am basically trying to distribute several web page scraping tasks among different threads, and have the results from each added to an Array which is ultimately returned by the backgroundrb worker. Here is an example of what I''m trying to do in a worker method: pages =

Hi, Ok, As i promised.. I am working on new version of BackgrounDRB, which is getting close and will be out soon. I need some feedback from you guys. So, please reply back. The code has changed significantly and its no longer using DRB. But I will keep the name BackgroundRb. Ok, in new API, a worker looks like this: require "net/smtp" require "guid" class NewsletterWorker
