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 g...

Hi, we are trying to use BDRB for background processing of long-running reports, and have two issues - one is that worker does not see our Report class from Rails, throws a: /var/apps/ror_trunk/vendor/plugins/backgroundrb/server/master_worker.rb:22:in `load'': undefined class/module Report (ArgumentError) from...

Hi, I''ve been having some issues integrating bdrb on a cruisecontrolrb server It''s related to the way we stop the bdrb server. The thing is, right now when we stop the process we are killing the parent of the group of the process. This is ok if you''re running script/backgroundrb stop directly from the console, but if I''m...

...r serving the single application. All Rails instances share the same database and use the database as a session storage. Memcached is also part of the picture. I''m looking into using Backgroundrb for some large uploads / parsing task that provide progress status updates (via ajax calls). Bdrb would run on each Rails server using drbunix (domain sockets) and not on the dedicated / shared Bdrb server. In this scenario it is not known in which Rails engine will the status update request land. It may or may not hit the engine where the Bdrb worker has been created( we don''t plan f...

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...

I have two workers (ie two files in my RAILS_ROOT/lib/workers directory) on my Rails app. When I run a top on my box, I see *three* processes called packer_worker_r. Shouldn''t I just be having two? What is the third process for? Here is an extract of the output from my top command. The PIDs are 7084, 7085 and 7083. ============================================ PID USER PR NI VIRT

Hi, Just wondering how you setup and get bdrb running without rails? Many thanks

Hey there bdrb''ers! I have been so very busy with http://engineyard.com that I have not had time to complete the new release of backgroundrb. But I have done substantial work towards it. It is basically an entirely new beast with a complete rethinking of how it works. I have put up a zip file...

Hi- Danny Burkes here from Lingr (http://www.lingr.com). We''re evaluating bdrb and so far, so good. It''s deployed in staging now and seems to be working fine. I have a couple of questions that I couldn''t find references to in the archive, so here it goes- 1. Is there any way to do a "graceful" stop of bdrb? What I mean is, I want to stop...

...all, I get this intermittent error saying OpenURI::HTTPError. At the bottom of the email is what is reported in my backgroundrb_server_<port>.log file. The process_netflix_reviews method is parsing (in the background) Netflix''s RSS feeds. This error also pretty much brings down the BDRb process and to recover, I am forced to do a ./script/backgroundrb stop ./script/backgroundrb start Once I''ve done this, it chugs along fine - even for the same URI it crashed on last. Until at some point in the future it barfs on another URI and I need to restart BDRb... This has been ha...

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 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

My Rails site uses BackgroundDRb and I have a couple of questions: 1. Can someone point me to some sample code/examples for how to use thread_pool? The website doc says to add a line ====== pool_size 10 ====== in my Worker class which seems straightforward. I wasn''t able to understand this part though: ========= thread_pool.defer(wiki_scrap_url) { |wiki_url| scrap_wikipedia(wiki_url) }

Hi all, i was using bdrb a while ago and it wasn''t stable enough in version 0.2.1 for doing the job - it loss jobs or did execute only the first one invoked and so on. Now i gave the new version a try and i found a bug at playing around. When i start a worker_method over the normal Unix scheduler bdrb will st...

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 #

...ger_args => { :start => Time.now }) => 2 >> MiddleMan.schedule_worker(:class => :my_worker, :job_key => :foo, :worker_method => :do_work, :worker_method_args => "d", :args => "_d_", :trigger_args => { :start => Time.now }) => 3 >> bdrb log #1: 20070515-13:55:27 (10865) MyWorker#do_work. args: _a_ 20070515-13:55:32 (10865) MyWorker#do_work. args: b 20070515-13:56:27 (10865) MyWorker#work done, deleting self. args: _a_ 20070515-13:56:32 (10865) MyWorker#work done, deleting self. args: b bdrb log #2: 20070515-13:55:22 (10864) Lo...

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

Hi there, In the latest releases bdrb attempts to load all models during startup routine. We have models that depend on the particular RUBY_PLATFORM but they live in the same models directory. It seems that the inability to load them stops bdrb. Could the models requiring / loading be done one demand, the same as Rails does? thanks, e...

Hi, Thanks for the help getting the new backgroundrb working, things are working fabulously now. I have two questions: 1) I have a few basic methods I need available on all my workers in order to communicate properly with my application... it seems to make the most sense right now to subclass BackgrounDRb::MetaWorker, or make a mixin module, because I''m actually extending some

...reactor loop. In a nutshell, you are not encouraged to use threads in your workers now. All the workers are already concurrent, but you are encouraged to use co-operative multitasking, rather than pre-emptive. A simple example is, For implement something like progress bar in old version of bdrb, you would: - start your processing a thread (so as your worker can receive further request from rails ) and have a instance variable ( protected by mutex ) which is updated on progress and can be send to rails. - With new backgroundrb, progress bar would be: proces...
