Req: Workers as singletons
Hi,
it would be nice to be able to specify workers as singletons. By this
I mean that every call to the new_worker method returns the same
instance of said worker. This can be done transparently either by
adding a new argument to new_worker (something like :singleton =>
true) or adding a new method, like I did in my installation of
BackgrounDrb:

A 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

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.

delete_worker doesn''t kill the thread?
I made a worker that run an infinite loop and does the following:
while true
@logger << "logging #{Time.now}"
sleep 2
end
In my secong console I did:
tail log/backgroundrb.log -f
This is so I could see the line getting added to the log every 2
seconds.
Then in my other console I started script/console and created a new
worker. Then killed it with

Updates and Fixes on Trunk
Hi,
I am pushing some updates and fixes that addresses much of the issues
that we talked about since last couple of days.
1. Use configuration option :debug_log: false to disable
backgroundrb_debug.log.
2. As shown below, use lazy_load option to disable aggressive loading
of models ( and somewhat stupid too).
3. MiddleMan.delete_worker(:worker => :foo_worker) will now ABORT the

Mongrel + BackgrounDRb + File Column = Upload Progress Bar?
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.

Forward of moderated message
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

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. Here''s my code:

BackgrounDRb background task runner and Application Wide Context Store
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.

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,

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:

Update
Folks-
I just commited another revision of the plugin. Nothing huge in this
update but some extra features. Acl lists are now configurable in the
config file. So you will want to blow away and recreate your config
file again. Thanks to Georg Friedrich for this.
And I applied Gunter Ladwig''s patch for singleton worker classes.
These are workers that only have one instance of

can a worker commit suicide?
Can a worker kill themselves when they''re ''done''? Or do I have to do that either from the controller or the worker manager?
Thanks,
Bill

Zombies?
Hey all,
Quick question about handling completed workers...
Most of my workers are one-offs that just let me spin off a long-running
file transfer process and then they just need to self-destruct when
completed. Thus, at the end of my do_work, I just call self.delete to (in
theory) self-destruct.
However, while checking the jobs.size from the console, I''ve noticed that

backgroundrb and autotest
Hi,
First, thanks for the plugin. Sorry if this is not strictly a
backgroundrb issue but I thought others on this list might have come
across this problem.
I''m trying to run the test that comes via the worker generator. The
test works fine when running ''rake test_functional'', but when the
tests are run by autotest I get "uninitialized constant BackgrounDRb"

Large requests break BackgrounDRb
Hello, I think I may have discovered a bug in BackgrounDRb. It seems that
when the data being requested is large (via send_request), say in the range of
64k+, it crashes or at least incapacitates BackgrounDRb.
For example, take these two workers:
class SmallWorker < BackgrounDRb::MetaWorker
set_worker_name :small_worker
set_no_auto_load(true)
attr_reader :payload

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?

:worker_method => :auth)
and then

Memory leak?
I am using BackgrounDRb to resize images after they are accepted into
our system. However, it has become clear that this creates a memory
leak. I''m not sure exactly where the leak exists, but I don''t think
it''s in my own code as it is presently being used in production and
has resized thousands of images without a leak occurring, thanks to
calling GC.start
