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.

Creating workers from workers?
Since MiddleMan is an uninitialized constant in a worker how do you
create new workers inside a worker?
Thank You,

Connection to backgroundrb is lost when exiting action method
Hey.
I have a very annoying problem, and was wondering what is wrong.
Suppose I have backgroundrb running, and then I have an action in some
controller. In the action I define a worker. When leaving the action,
suddenly the connection to backgroundrb is lost:
DRb URI: druby://localhost:22222
Pid: 3976
Autostart...
done

uninitialized constants in worker class
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

Noob needs help installing backgroundrb on Windows XP
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

Cannot invoke ActiveRecord subclass accessors in DRb worker
Hi there,
I''m trying to create a worker to do some asynchronous web client work
and update the data model with its results. It seems, however, that
every call I make to an ActiveRecord subclass causes the whole thing
to block. At least I think it''s blocked. Right now I''m just using
debug log output.
Is there a decent way to debug/test workers I can try?
Is there any

Using BackgrounDRb to replace nested loops?
In response to my Rails Weenie post today[1], someone mentioned that

Stopping DRb after using BackgrounDRb::MiddleManDRbObject.init
Hi,
I''m having a problem where connections started through
BackgrounDRb::MiddleManDRbObject.init are not stopped, resulting in an
ever growing established connections between my Mongrels and remote
backgroundrbs
I added DRb.stop_service to my code executed after requests that init
MiddleManDRbObjects but that does not help.
Any ideas?
Thanks,

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:
def get_worker_by_class(klass)

A couple of problems
Hi Ezra,
Thanks for the great work on BackgrounDRb. I have come across a
couple of problems.
1. I wanted to define a simple class in the worker file to wrap up and
pass back some data to my controller. It seems that if I create the
class either inside or outside of my worker class (in the same file)
it gets wrapper by a DRb::DRbUknown object and therefore cannot be
accessed from my controller.

error message for record not found ?
I''m using backgroundrb for session management and deletion of visitor-entered information when a session is abandoned. The visitor can either click a button to end their session and remove their data, or backgroundrb will do it for them after 5 minutes of inactivity.
Everything''s working fine, I think. If the visitor explicitly logs out, then when the worker checks for their

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

where do uncaught exceptions printouts go?
Hi,
I have a worker, which should have thrown an uncaught exception and dumped the stack in the do_work
method, however I saw no dump or indication of any error in any of the logs.
This makes it very hard to debug, where does stdout and or stderr go? How canb I know if it gets
some kind of error? (in this case not being able to find a class).
Thanks

Drb Connection error on multiple dispatch.fcgi ''s
Hi All,
I''m using Backgroundrb as a general purpose long-running-task back-end
(upload processing, email sending, etc), and it''s been a great solution.
However I''ve recently run into some some intermittent connection issues
that have me baffled. I''m running on apache2/fcgid and the problem
occurs in both devlopment and production mode. The problem seems to

Thread Pool Size?
Hi All,
It might be lack of sleep, but I am struggling to accurately limit our pool
size. It seems like I can specify it on the server with the -s command
line option and also on the client via the YAML pool_size. Is that right?
Which one wins?
Our problem is that we are getting about 40 threads on each backgroundrb box
and it''s flooring our db and each bgrb box.
We want around 8.

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.

BackgrounDRb newbie stuck at first base. Fresh pair of eyes needed
Can''t believe I can''t see the problem here, but after a few hours
bashing my head on a brick wall, going to risk looking stupid by seeing
if anyone can point out my idiocy (that''s the worst thing about coding
on your own).
Trying to get BackgrounDRb to take over the scraping task which is
currently being done in a Rails controller. That''s not the problem at

Production RAILS_ENV / DB Selection
Hey all,
I''m having some issues moving a project that incorporates Backgroundrb onto
a staging server... For some reason (surely of my own doing), my RailsBase
workers are insisting on using trying to access my development DB instead of
my "production" DB.
When I try to load a model object from within a worker, I get the following:

nil object / slave server problem
I''m just getting started wtih backgroundrb, and unfortunately hit a
snag right away... I''m running the latest releases of rails,
backgroundrb, slave and daemons.
I created a simple worker class, using the generator, which currently
does nothing but print the arguments that are passed to do_work. I''m
running backgroundrb using ''./script/backgroundrb
