Recommendations for eternally-running backgroundrb workers?
I''ve got some workers that I want to have running all the time. Right now I''m just launching them manually, by requesting a special page in my rails app that includes lines like: MiddleMan.new_worker(:class=> :receiver, :job_key=>:r, :args=>{:sleep_time=>10}) This strikes me as a really weak way to fire up my workers. I basically want to automate things so

querying status of worker with job_key
Hi, Is it possible to start a worker with job_key and then ask_status of that specific worker with the job_key?

getting started
Hey all, Been reading through all the old posts (and the docs) to familiarize myself but I still feel a bit lost. I''m on trunk and am having a bit of a hard time knowing where to start with the particular I''m trying to solve. So far, I''ve downloaded backgroundrb, done the basic rails setup, created my worker and started it using `script/backgroundrb start`.

BackgrounDRb New release.
Howdy Folks- I''m happy to announce a new release of BackgrounDRb! I have added quite a few new features and included some nice patches from folks on the list. $ script/plugin install svn://rubyforge.org//var/svn/backgroundrb All of the code now stays within the plugin and the start and stop scripts are now just stubs. This makes it easier to tweak or figure out how it works.

nil-error
Hi all, I''ve got the error below in my backgroundrb_debug.log. I''ve tried to reproduce the error in the development environment, but the only way I can get the same thing is by calling ask_work with a bogus worker name. Calling it with the production code causes no error. Here''s an example of what the code calls: MiddleMan.ask_work(:worker => :agronomy_worker,

Using my models
I''m working on upgrading my app to the latest version of backgroundrb. Everything went find until I tried to execute my tasks. Here is my simple worker for testing: class MscWorker < BackgrounDRb::MetaWorker set_worker_name :msc_worker def create(args = nil) # this method is called, when worker is loaded for the first time end # Send a message to everyone def

Get "some read error" on calls to worker
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

problem with worker status
Hi, I have a page were users can start jobs that may take several hours to run. BackgrounDrb is perfect for me and seems to be working well most of the time but some times I have the following problem: My worker is set up like this: class UploadWorker < BackgrounDRb::MetaWorker set_worker_name :upload_worker set_no_auto_load(true) def create(args = nil ) file = args[:file]

Delete a busy worker
I thought I could delete a busy worker by calling MiddleMan.delete_worker, but doesn''t seem to end. I believe this was possible in 0.2, is it not in 1.0? thanks, Zach -------------- next part -------------- An HTML attachment was scrubbed...

Trouble using backgroundrb
Hi all, I''m a newbie to backgroundrb and am having trouble integrating it into my rails-app. I''m using namespaces to differentiate between the parts of my app. When I want to create a new worker, it seems that it cannot find the worker object.

Autostarting and job keys...
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

can''t call any methods on workers
Hi, I''m a long time backgroundrb user, still stuck using the very ancient original version from Ezra (not even Ezra''s 2.0 version, I''m using the one that didn''t really have a version number). The 2.0 version did very little but crash for me. Anyway I finally got some time set aside to try out this new version you all have been developing.

Polling is REALLY slow
I''m having some trouble with using brb for polling for work. Basically, what I want to do is update the state of a record and have brb notice and start a process. I do not want to call ask_work for each process because there may be several places where the object''s state is changed, and I only want to process once. Plus, I can schedule things better this way. My first thought

Cannot connect when spawning new workers on demand
Hi! I''m using the latest&greatest backgroundrb with rails 2.0.2 on ubuntu dapper. I''ve made an app that lets you run a query on several servers at once, which are selected at runtime. Therefore, for each server that is selected, I spawn a new worker and assign its work. After everything is completed, the workers are deleted. I often get this error:

BackgrounDRb 0.2.0 Release! Complete rewrite.
Hello Folks- I am really happy to announce the release of BackgrounDRb 0.2.0 . This is a complete rewrite and re-architecture of this codebase. I want to thank skaar for all of his hard work. I put out a call for help with the new architecture and skaar stepped up bigtime. I had already written the new scheduler and cron compatible syntax and moved to multi process architecture. But he
