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

Problem with drbundumped?
I''m not sure if this is a problem or not, but it definitely henders
the way one would use the passing of objects to the drb server. Isn''t
the point of passing objects to the drb server to act like its
passing to just another local method? When I pass an object to the
drb server a lot of the useful methods are gone. Such as id() or class
() or inspect(), etc. I spent a

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.

strange issue with backgroundrb behind apache/lighttpd
I''m getting strange data back from my worker whenever I run our rails
app with more than one dispatcher under lighttpd.
just to give some info on what the app does:
user submits data to rails app. rails app hands off data to worker,
which goes and does it''s thing, storing results in an array of
response objects (the array is an attribute of the worker). the
response object

"include DRbUndumped" error
Hi,
I am getting my hands on trying the cool BackgrounDrb plugin.
Following various discussions and suggestsion, I included "include DRbUndumped"
in my ActiveRecord model. However, the following exception occurs
after I tried this and hit the page that uses this model. Does anyone
know why this is so? Is it possible that an object cannot be

''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

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?

[Tip] Application Wide Context Howto
Friends-
I see more and more folks wanting an application wide context object
that will work regardless of server software(webrick,mongrel, fcgi''s,
scgi''s) This can be a very useful technique if done correctly. Here
is a little info that I have gleaned on a great way to do this type
of thing.

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

Drb Connection error on multiple dispatch.fcgi ''s
Hi All,
I''m using Backgroundrb as a general purpose long-running-task back-end

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

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.

openssh 2.9p1 on Solaris 2.6 with AFS
Jan,
maybe I should check the /afs information that you pointed me at
in a subsequent email first, but I wanted to update you on what
happened following this path:
I did get some mileage out of both of your suggestions below,
but still did not make it through (now working with openssh-2.9p2):

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:
