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.

Problems with ActiveRecord in workers
Hi *,
are there some special settings except of "load_rails: true" to make
ActiveRecord models accessible within my workers?
I''ve just installed the latest version of this great plugin, but I keep
getting
undefined method [] for #<DRb::DRbUnknown:0x12345> (line 105 in
backgroundrb.rb)
when one of the arguments for the worker is an ActiveRecord object.
I assume that

''m having trouble with BackgrounDrb
Hi. I thought that BackgrounDrb was the perfect solution for my long
running report production tasks.
But I can''t seem to get anything useful back out of it.
I set up a simple test worker that just does
class TestWorker < BackgrounDRb::Rails
attr_reader :pupil
def do_work(args)
@progress=0
@pupil=Pupil.find(3)
sleep rand*10
@progress=100
end

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:

undefined method `'' for #<DRb::DRbUnknown:0x2501bd4>
I tried installing BackgrounDRb today. Followed the readme, made a
little worker for myself and executed it within the code. But I keep
getting this error. I must''ve gone over the README a zillion times.
Any idea what it is?
undefined method `[]'' for #<DRb::DRbUnknown:0x2501bd4>

Testing worker classes
Hi,
Does it make sense to test a worker class by calling
Middleman.new_worker? Or should I just be testing the functionality in
the do_work method, with, say, a mock object. This seems like a really
ugly DRY violation: you''d need to keep the code in the mock and the
real worker in sync.
That''s the philosophical half of my question. In fact, until someone
tells me why I

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 problems with results and MiddleMan
Hi there,
I''ve been experimenting with implementing BackgroundDRb in my rails app but
am running into some problems.
The primary problem I''m getting is in cleaning up worker threads, or getting
any kind of response out of worker threads.
If try using the response function/hash in my Worker the worker will not
execute reporting that response is an unknown variable or function.

Exception when doing DRb remote calls from a BackgrounDRb worker

I am trying to make DRb calls to a external server from a backgrounDRb

:job_key acting weird?
Hi all
I''m experiencing something strange with a :job_key, it took me a very
long time to find out a worker wasn''t doing it''s job because of the
name of my job_key. The first one I tried was :make_kohier, and with
that name (and lot''s of other ones) I can''t get the worker to work. I
do get my key in return, but the job doesn''t start

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,

backgroundrb not cleaning up tmp files?
I just had an interesting issue on a production system that has been
running nicely for about a year. There were approximately 10,000
backgroundrb temp files in the /tmp directory. It looks like
backgroundrb wasn''t cleaning them up.
I noticed it with the following error:

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

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

Yet Another Problem with BackgroundRB
Hi!
My cron-based worker is being indeed invoked by backgroundRB at
correct times. But... After several runs it can no longer find DB
columns! The same query, which was running OK an hour ago starts to
throw MySQL error about unkown column in where clause. If I restart
backgroundrb it works for some time but stops working after several
invocations.
Has anyone epxerienced the similar beahviour?
