BackgrounDRb release 1.0 available now
Hi Folks,
I am glad to announce 1.0 release of BackgrounDRb.
This would be a major release since 0.2 release of BackgrounDRb.
Here is a brief summary of changes:
- BackgrounDRb is DRb no longer. It makes use of EventDriven network
programming library packet ( http://packet.googlecode.com ).
- Since we moved to packet, many nasty thread issues, result hash
corruption issues are totally

Upper limit to number of jobs queued by BDRb?
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 get
done serially. As long as N is 255 or under, everything works like a charm.

best approach to managing workers and getting status
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])

right usage of bdrb
Hi,
i''m going to implement a syndication-service, which will get lists in
xml with some meta-data an enclosed video files, which will get encoded
at the end. The syndication run will be startet every five minutes of
a full hour.
So i thought to build 4 Worker. One for checking which feeds to
syndicate (syndication_worker) at a specific time, one for processing
the list

thread_pooling sleeping
I''m trying to run a single worker that could perform a periodic task
for a given user.
>From a controller, I imagine something like:
def start_job
MiddleMan.ask_work(:worker => :foo_worker, :worker_method => :perform_task,
:data => { :user_id = current_user.id })
end
def check_job
@status = MiddleMan.ask_status(:worker => :foo_worker)[current_user.id]

pre-release version of backgroundrb available now from svn
Hi,
A pre-release version of backgroundrb is available now from svn.
Download it from here:
http://svn.devjavu.com/backgroundrb/branches/version099/
Since this release marks significant migration from existing
practices, i intend to keep trunk untouched for a while.
There are no install scripts, but you should copy "backgroundrb" file
from script directory of plugin to script

BackgrounDRb version 1.0RC1 available now
Hi Folks,
BackgrounDRb is a Ruby job server and scheduler. Its main intent is to be
used with Ruby on Rails applications for offloading long-running tasks.
Since a Rails application blocks while serving a request it is best to
move long-running tasks off into a background process that is divorced
from http request/response cycle.
This new release of BackgrounDRb is also modular and can be used

Unable to load Models which reference plugins?
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

Job Queue
After some initial stumblings, I think I''ve got the hang of
backgroundrb. It''s great! I''d been thinking for many many months how
cool something like this would be!
I''m trying to make a "job queue". That is, a pool of worker threads
monitor a queue. When a job appears, one of the workers grabs it and
executes the task. When complete, the worker

failed to find slave socket - (RuntimeError)
Hi everyone,
I''ve a class that try to spawn two workers, every 5 seconds.
The code is something like:
while true do
MiddleMan.new_worker(:class => :researches_worker,:job_key
=> :researches)
MiddleMan.new_worker(:class => :products_worker,:job_key => :products)

I''m using ":job_key", so if a worker hasn''t already ended its work

Sequence of multiple background process submissions
I have a question on how multiple b/g processes that are kicked off get
handled in terms of sequence/schedule.
On my site, a user enters an RSS feed to be processed and since this takes
about 5-10 secs, I pass the process off to a background job and meanwhile do
some Ajaxy spinners and tap-dancing until the job completes and then
redirect_to the appropriate page. This works great.

Threadpool and queuing of tasks
I recently switched over to v1.0, and things are rolling along pretty well.
However, one thing that has always been a little confusing to me is knowing
when to use thread_pool. Since most of my bgrb workers are called from my
web app to process rather than being scheduled, I''m using the thread_pool
for every call. Unfortunately, that means that I have to split up workers
by how many

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`.

Query All Worker
What does the method query_all_workers() do? There is no documentation
on what this method returns (1.0.1 version).

unit tests?
Ezra et al:
I have this problem:

Any progress on it? Or are unit tests simply impossible for now?

Using the ip flag
Hey All,
I am looking for an example of the proper config settings for background rb to run my rails app and my backgroundrb instance on separate machines (or more precisely, to have a rails cluster with one backgroundrb machine). Does anyone have such examples?
Thanks!

Some more updates, enhancements and fixes
Hi Folks,
Well, Yesterday I pushed some more updates that I was cooking since
last couple of days. Here is a brief list:
1. Results from worker stays even after a worker dies.
2. You can ask backgroundrb to store status objects in memcache
cluster now. by default its stored in master process memory, but I
have introduced an option to allow it to be stored in a memcache
cluster:

adding results from threads to a collection and returning it
Forgive me if this has been addressed somewhere, but I have searched and
can''t come up with anything.
I am basically trying to distribute several web page scraping tasks among
different threads, and have the results from each added to an Array which is
ultimately returned by the backgroundrb worker. Here is an example of what
I''m trying to do in a worker method:

How you want BackgrounDrb to behave
Hi,
Ok, As i promised.. I am working on new version of BackgrounDRB, which
is getting close and will be out soon. I need some feedback from you
guys. So, please reply back.
The code has changed significantly and its no longer using DRB. But I
will keep the name BackgroundRb. Ok, in new API, a worker looks like
this:
require "net/smtp"
require "guid"
