similar to: Regarding New QueueWorker class

Hello all, I''ve come up w/ a worker class that manages queued jobs using a fixed number of child workers. Well, that''s not quite true -- a new worker is spawned for each job, but you set the total number that may exist at once. There are three components: 1) queue_worker.rb: The singleton worker that manages the child workers. You probably want to auto start this. Make sure you

Hi all, I just read Ezra''s article on BackgroundRb and decided to use it one of my projects. I installed the plugin into my rails project using script/plugin and then ran rake backgroundrb:setup to copy the yml scripts. Now my backgroundrb.yml looks like ======= --- port: "22222" timer_sleep: 60 load_rails: true environment: development host: localhost database_yml:

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,

Hi, I am trying to create a pdf using ruby jasper.

Guys All the recent discussions recently, and the knowledge of a 2.6 port, of WRR has made me very keen on trying it. I had a look at the docs and examples know but my mind is not in a very receptive state. Take this simple example. Incoming internet connection of 1mbps. Shared between up to 25 users simultaneously. I know that WRR can fairly distribute the traffic amongst the currently

Hello, Bravo Ezra for Backgroundrb! What an elegant piece of engineering. I envision many folks like myself looking at our CPU hogging executables and finally seeing a clean path to the Web. I was wondering if any folks have a good strategy for calling out to a C++ (or any other compiled) executable from a worker. Is the only option to call system() from a worker? That feels a bit unsatisfying.

Hello All- Is there anyone out there that wants to take over as maintainer of the backgroundrb project? I feel bad because I know lots of folks use it but I absolutely do not have time to work on it anymore :(. I''m looking for a new maintainer, I would give you all the access to the project you need and try to help you come up to speed on the codebase. If anyone is

Is there something special I need to do to access session data in a worker? I''m using an AR session store. I''ve been working with Ezra''s tutorial, modifying it a little here and there to figure it out. So I changed the progress bar to a simple count-down in the worker which sends back the count to display in the view. No big deal. But if I try to access session

Hi the list people, hi Ezra, I just read from this message http://rubyforge.org/pipermail/backgroundrb-devel/2006-July/000134.html that BackgrounDRb will offer a way to kill a worker from within itself. As this message is from 7/25, I wonder if this feature has been added since. If not, is there any way to do it? I tried this: MiddleMan.delete_worker(@_job_key) But it raise: uninitialized

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 there, I''ve been digging around trying to find some information (mostly examples) on how one would handle a progress bar upload using BackgrounDRb and File Column. I did read http://backgroundrb.rubyforge.org/ and Ezra''s blog of course, but I still have a few questions. I made a simple upload form (as a test) that is submitted to the "upload_song" action. def

First of all, I''d like to do what I''ve seen several others here do: thank Ezra and any other contributors for producing a really great plugin. Even though I''m having some minor problems, this is all so approachable and easy to work with and dig into... I hate to think of the hoops you''d need to jump through (both as creator of such a system and as a user) to

Friends- I''m happy to annouce the first alpa release of BackgrounDRb. This is a small framework for managing long running background tasks that allows for ajax progress bars and more. It also serves as an Application wide cache and context store for when you need something like sessions but shared between users and multiple backend processes like fcgi''s or mongrels.

First off BackgroundRb rocks!!!!. Top marks Ezra, it''s gone a long way to stopping us from doing a nasty curl/cron hack :) Okay so here''s what we''re using it for. We''re synchronising data from a Filemaker database, via web service equest, into a mysql database via a rails model called ''Syncer'' [How''s that for an oddball use case!].

OK I know whats happening. Your while loop completes and calls kill on the worker before your task_progress controller method ever gets called> So the worker is deleted and when you try to access it from rails you get an error because there is no longer a worker at that job key. The kill method is meant to be used within a worker that you fire and forget. If you want to get the

Ezra, Suppose a chatroom application, a RailsApp + 2 backgroundrbs: MiddleMan1& MiddleMan2, running in 2 machines. When Chater1 login, RailsApp call MiddleMan1 to get something about Chater1 from db to memory, like his contacts or other personal settings. When Chater2 login, RailsApp call MiddleMan2 do the same thing. But who is reponsible for the Global Data? like a Online Chaters

Hey Greg- Yes I am sorry, the new architecture uses fork and named pipes and a bunch of unix stuff to do its magick. Now you may be able to port it to qwork on windows, but I don''t think it is possible :( I''m really sorry about this but I need this thing to be as robust and solid as it can be and in the end windows isn''t compatible. Now you may be able to

Hey Folks- I have just pushed a new release of BackgrounDRb to rubyforge. It has some nice new features to allow for usage of your ActiveRecord Models within your worker classes. I also added a config file for setting hosts and ports and if you want to load rails or not. Please have a look and let me know if anyone runs into any issues. If you already have an older version installed

I''m trying to use BackgrounDRb to do image processing on large uploaded zip files of images, but $script/plugin install svn://rubyforge.org//var/svn/backgroundrb gives me this: /usr/lib/ruby/1.8/open-uri.rb:88:in `initialize'': No such file or directory - svn://rubyforge.org//var/svn/backgroundrb (Errno::ENOENT) I can install the old version with $script/plugin install
