similar to: Status of your worker pool

We have a fairly expensive task that we''d rather not schedule too many instances of in parallel. Couldn''t get pool_size to limit the amount of workers, and I figure that''s hardly optimal anyway, so would like to have the work queued up for a single named worker instead, running as soon as possible. Using MiddleMan.schedule_worker() with :job_key does start off a

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 of the new code base in the hopes that some folks will be able to start playing with

Hello there, I need a Worker Class to be Singleton-like, that means there must be at maximum one Instance at a time. When a new Request is made to create another worker of this type, it should return and wait for the other instance to be destroyed. what i need to do: i have a worker who needs to do sth with java and openoffice, and it seems when i have more tha one worker simultaneously,

got a wierd problem maybe someone can help with. whenever i try to pass an array or AR objects to my worker, i end up with a DRb object in the worker...here''s an example class SearchWorker < BackgrounDRb::Rails attr_reader :resources def do_work(resources) logger.info resources.inspect end end class SearchController < ApplicationController def start_search

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

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 - >

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 folks, does backgroundrb delete workers who exited do_work()? i experienced it doesnt (and that freaked me because i didnt know that for several hours). is there a way to let the middleman or so delete workers who did their job imediately after they''re done? if not, i coud think of that as a nice improvement. greetz -- Michael Siebert <info at siebert-wd.de>

Hello, i need to have some jobs scheduled in the background and executed at specific times. I wanted to make a worker who does that - and it works a little bit - but i had an enlightment... why not make bgdrb itself play that role? i mean, the MiddleMan has already everything needed! a timer thread, currently used only for deleting old workers and the workers itself. since im not familiar with

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 start as much as possible the worker_method after the :end-time is reached.

Hello, i need to require a file located in /lib from a worker class, but when i try to start the backgroundrb server, i get something like d:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in `require__'': no such file to load -- ./lib/office_thumnail_generator.rb (MissingSourceFile) i tried it with and without lib, with RAILS_ROOT, nothing worked, altough the paths look good

Hi, i had a little problem a few minutes ago. somehow the backgroundrb process got mad and consumed all the cpu power available, i think it got an endless loop. i dont know why, no exceptions were thrown. could this be an issue of bgdrb or ruby or rails (as i load the rails environment) -- Michael Siebert <info at siebert-wd.de> www.stellar-legends.de - Weltraum-Browsergame im

I was using an older version of backgroundrb and today I started to play with the most recent release. First up, I''d like to say, thanks so much for this library and thanks for making it more stable. From the looks of things, I think it''s going to be easier to use now than it was several months ago when I first started using it. I''d like to make sure I''m using

(Sorry my last email had the wrong subject) Hi, I''ve just installed background rb 0.2.1. When I try start a worker in my application controller I receive the following error: wrong number of arguments (2 for 1) - (ArgumentError) /home/chris/projects/call_manager/trunk/call_manager_app/vendor/plugins/backgroundrb/server/lib/backgroundrb/middleman.rb:211:in `initialize''

I am new to this list and relatively new to the backgroundrb plugin,. So first i will say hello to everybody here, especially to Ezra Zygmuntowicz! I played a little bit with a dummy worker and so far everything worked well. But now i want to do real work in a worker but now i get that error[1]. It looks like that the constants configured in environment* configs are not available to the worker

Hi Folks, I''ve got a tiny little problem using MySQL-backed ActiveRecord in my worker class. Sometimes it just blocks infinitely when I try to access it. I don''t know whether it is in AR itself or in the SQL driver. It just stops doing anything, logging nothing, no exceptions are raised. I don''t know if it matters that I call the worker''s methods via

I''ve now got 5 processes auto started. But I when I query the MiddleMan for their keys (in script/console), it doesn''t find them. Looking at the start script, it looks like it might be creating a new MiddleMan object for each autostart BackgrounDRb::MiddleMan.new.new_worker(:class => entry[''class''], Even changing it to

for some strange reason this error occours when i create one worker from another BUT only when i derive worker class from Worker::Base instead or Worker::RailsBase - when change it back it works fine, child worker can have empty do_work, but this error still ocours Bad file descriptor (Errno::EBADF) /var/lib/gems/1.8/gems/slave-1.2.0/lib/slave.rb:214:in `for_fd''
