similar to: Exceptions in workers

Say I have a job that runs every minute, but it takes longer than a minute to execute. Will it start a new job every minute? If it does, then how would I make a job that sleeps for a certain amount of time, then restarts? I have a job that could take an hour or two to complete, and I don''t want to have multiple copies of that job running at the same time. Joe

I have been facing this damn ugly issue since quite sometime. So this worker reads RSS feed from Yahoo news and stores it in a DB. The worker is scheduled to run at every 40 minutes and my background_schedules.yml looks like this: feed_worker: :class: :feed_worker :job_key: :feed_worker_key :worker_method: :do_work :trigger_args: :start: <%= Time.now + 5 %>

I''m running the latest from svn (rev 285). I''ve been having a problem launching a process repeatedly. What happens is that I get a debug message "some read error" and then the worker refuses to run again. I''ve stripped my worker down to just doing a puts and it still happens. Like the other threads I want to launch my workers as needed, however I get the

I tried to upgrade my existing application to RC2 last night. Like many, I use this mostly for running scheduled tasks. For the moment, I''ve abandoned the effort, but am looking forward to being able to use this. Feedback below: First, the reason I was looking forward to this upgrade was to use the threaded scheduler. I have an application with long-running tasks. I found that

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

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 All, I have this small doubt. Does backgroundrb have anything to do with dispatch.fcgi? some dispatch.fcgi are taking memory as much as 186 MB .... this is monstrous man... Also, if i put load rails environment with backgroundrb.yml file to be false.What will happen? i just loses access to db through ActiveRecord right? I can still use normal mysql gem to access db and modify the

Hi, I''m using backgroundrb 0.2.1 and having problem with worker processes staying around when the rails application does not explicitly delete them. Is there a way to automatically delete the worker processes when it has completed the job? Also does killing the process manually (using kill command) harm the backgroundrb server? I have some occasions where the backgroundrb server just

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

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

Sorry for attaching patches in emails to the mailing list, but I''m still unable to login to Devjavu for Backgroundrb (I''m able to login just fine for Merb''s Devjavu and submitted a ticket successfully). Anyway, I encountered a bug when trying to #ask_status of a worker before it''s run (or rather, before its result_hash has been set to something). Not sure why

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

I''m getting the following error (when doing script/backgroundrb start) on my local machine, which is running os x 10.4.11. However, it works just fine on my linux server. RAILS_ROOT/vendor/plugins/backgroundrb/lib/../framework/nbio.rb:64:in `dump_object'': undefined method `write_nonblock'' for #<UNIXSocket: 0x135b5f4> (NoMethodError) I just grabbed the

I am sure..again I am missing something, but I am trying to start a worker, when backgroundrb starts and it doesn''t seem to work. Here is my config/backgroundrb_schedules.yml file: feed_worker: class: feed_worker job_key: feed_worker_key worker_method: do_work trigger_args: repeat_interval: 20.minutes I even tried this from Rails controller: # def start_feed_worker #

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.

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, We are glad to announce shiny new release of BackgrounDRb, which will soon become 1.0. A quick summary of changes: - BackgrounDRb is no londer DRb, its based on event driven network programming library packet ( http://www.packet.googlecode.com ) . - Since we moved to packet, many nasty thread issues, result hash corruption issues are totally gone. Lots of work has went in making

Hi All, One can easily code a backgroundrb worker so as it can act as a worker queue, having reached a stable status, perhaps its time we should add this feature. Why? Because if you are already running your application using BackgrounDRb, perhaps you don''t want to manage other solutions when capability to do that is right there with you. Interface? This where i need feedback. You can

Hello, Does reload_on_schedule force the worker to be reloaded even if it is already running? Or does it just load the worker if its not running when the schedule fires? I want to load the worker at the scheduled time if its not running, but I don''t want to reload the worker if its already running. Make sense? Thanks, Scott

Quick question: If I want to schedule different worker methods defined in the same worker to trigger at different times, is this possible? Would the following scheduler yaml work? :schedules: :foo_worker: :worker_method: method1 :trigger_args: 0 */10 * * * * * :job_key: some_key_1 :foo_worker: :worker_method: method2 :trigger_args: 0 */15 * * * * * :job_key:
