URIS http://codeforpeople.com/lib/ruby/slave/ http://rubyforge.org/frs/?group_id=1024&release_id=5631 SYNOPSIS the Slave class forks a process and starts a drb server in the child using any object as the server. the process is detached so it is not required (nor possible) to wait on the child pid. a Heartbeat is set up between the parent and child processes so that the

Hi, I get the following error from my client program when I try to call delete after my worker is completed: goten at goten-server:~/projects/svn_working/m29svn_back/app$ ruby backup_app.rb {:done=>true, :txt=>["piping to tmp", "piping done", "getting youngest", "youngest got", "destfile

Ok two things that bug me 1) http://backgroundrb.devjavu.com/projects/backgroundrb/ticket/48 i thought i''ll just post ticket link - but well - it''s strange 2) when i switch base class from RailsBase to Base i can''t access MiddleMan - i get error NameError: uninitialized constant MiddleMan from (drbunix:///tmp/backgroundrbunix_localhost_2999)

Hi All, Real neophyte here, to both backgroundrb and ruby/rails in general. (Hey, we''ve all got to start somewhere, right!) :) I''ve just been playing around with the example code at http://backgroundrb.rubyforge.org/ , and trying to get all the pieces to work (btw, I''m using version 0.2.1). I did a ''generate worker example'', which created an

Hi! I''ve just a created a really simple rails scheduled worker for backgroundrb to start playing with : class SessionCleanerWorker < BackgrounDRb::Worker::RailsBase def do_work(args) logger.info "SessionCleaner> started" CGI::Session::ActiveRecordStore::Session.destroy_all( [''updated_at <?'', 120.minutes.ago] )

Greetings all, Unit tests are passing, but I''m having mucho problems getting brb to run without exceptions for more than 6 hours. I''m seeing a mixture of the following 2 exceptions: 20070605-11:26:56 (21497) failed to find slave socket - (RuntimeError) 20070605-11:26:56 (21497) /usr/local/lib/ruby/gems/1.8/gems/ slave-1.2.1/lib/slave.rb:435:in `initialize''

Hello all, I''m having some trouble getting backgroundrb set up so that all the processing happens on a single machine. I have 3 load balanced machines. Right now, all three run our web application and create MiddleMan workers to generate a large PDF report. However, because of the processing power needed to generate the PDFs, I want to change our setup so that two servers run

i found some questions and answers on mailing lists but there is still a problem - when i want to create new worker from within a worker - ::BackgrounDRb::MiddleMan.new_worker(:class => :second_worker, :args => {:id=>2, :text=>"slave"}) works but when i want to get reference to that object: ::BackgrounDRb::MiddleMan.worker(@second) yields: NoMethodError: undefined

Hi, I''m using backgroundrb to get RSS feeds and pass them back to the controller. I''m using the Ruby RSS library to parse the feed, which returns an RSS object. After that I pass the object into the results hash, but that''s when this error occurs. Basically, this is what I have: rss = RSS::Parser.parse(response.body) results[:feed] = rss # error! 20061120-15:46:19

It''s that time again friends. skaar has been at it again and has greatly improved the stability of the new system. And Ara Howard has helped a ton by working with us on the slave library to iron out the wrinkles./ The results is a lot nicer backgroundrb for everyone. I have to say another huge thanks to skaar. He has singlehandedly wrote almost all of this new version and many

I''m running the latest backgroundrb mainly for scheduled tasks support. As per the documentation I created the backgroundrb_schedules.yml with the following: simple_label: :class: :document_sorter_worker :worker_method: :do_work :job: :bleh :trigger_args: :start: <%= Time.now + 5.seconds %> :end: <%= Time.now + 10.minutes :repeat_interval: 1.minute Under

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

Greetings, I am seeing the following in my log quite a bit 20 + times per day. The stack-trace seems tin indicate an internal issue - is concurrency related? == 0.2.1 (Released November 28, 2006 - r162) My workers continue to function; on the next iteration I believe. Any thoughts are appreciated. cheers, Jodi allow_concurrency=true Scheduler.run failure: undefined method

In my app, I store the job key when a worker is fired off and then check back in periodically to see how its doing. The workers delete themselves when they''re done. I would expect when I try to get a worker that has been deleted, I would get nil or a proper exception, but instead I get: >> MiddleMan.worker(''foobar'') NoMethodError: undefined method

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 -

Hi there, We run several (3-4) Rails servers behind the reverse proxy / load balancing web server 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).

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 - >

I figured out that in the backgroundrb.yml, I had the old setting of making the database RAILS_ENV. It wasn''t a valid variable in backgroundrb 0.2.1, and it wasn''t reporting an error, so I had no idea. Once I changed it to ''development'' or ''production'', it started working. I found that if a worker has an error, it usually logs the error

Hi gang, Thanks to other help I''ve gotten on this list, I''ve got backgroundrb up and running using postgres alongside my rails app. I''ve designed the system to have several eternally-running workers that periodically poll the database to see if there''s any work for them to do, and set things up in the config file to make them restart quickly if any of them
