new BackgroundRB
Hey Greg-
Yes I am sorry, the new architecture uses fork and named pipes and a
bunch of unix stuff to do its magick. Now you may be able to port it
to qwork on windows, but I don''t think it is possible :( I''m really
sorry about this but I need this thing to be as robust and solid as
it can be and in the end windows isn''t compatible. Now you may be
able to

backgroundrb preview
Hi Ezra/skaar,
Wow man, the exercise was worth it. The connection closed problem with
socket as i mentioned in my earlier mails...completely disappeared,
and now i can connect only once to the socket and keep reading..till
end of its days.
Literally impossible with older release of backgroundrb.
This could also potentially solve the issues people were having with
ActiveRecord.

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

start a worker when bdrb starts
I am sure..again I am missing something, but I am trying to start a
worker, when backgroundrb starts and it doesn''t seem to work.
Here is my config/backgroundrb_schedules.yml file:
feed_worker:
class: feed_worker
job_key: feed_worker_key
worker_method: do_work
trigger_args:
repeat_interval: 20.minutes
I even tried this from Rails controller:

State of backgroundrb (dupe?)
Hi, pardon if this is a duplicate mail, I forgot to click the
subscription link the first time around.
I''ve been using backgroundrb for a while now (older version) and I''ve
had so many headaches because of it that I began looking for a
replacement technology. And then I saw the new and shiny backgroundrb
website, looking good!
Initially I used the version maintained by

Need help with singleton worker
We have a fairly expensive task that we''d rather not schedule too many
instances of in parallel.
Couldn''t get pool_size to limit the amount of workers, and I figure
that''s hardly optimal anyway, so would like to have the work queued up
for a single named worker instead, running as soon as possible.
Using MiddleMan.schedule_worker() with :job_key does start off a

backgroundrb launches concurrent instances of same job
Hi there,
Backgroundrb is working pretty well for me but I have a job that launches
two of the same job, apparently a minute(?) apart from each other. Should
this be happening if I have repeat interval enabled with a job_key? It
seems like it should wait until the job is finished before launching a new
instance.

worker starting twice
Hi gang,
Thanks to other help I''ve gotten on this list, I''ve got backgroundrb
up and running using postgres alongside my rails app. I''ve designed
the system to have several eternally-running workers that periodically
poll the database to see if there''s any work for them to do, and set
things up in the config file to make them restart quickly if any of
them

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

Intermittent "can''t convert Float into Hash" and results.rb
Hi,
I''m using backgroundrb 0.2.1 in a production environment and for most
parts I''m very happy. We are using it to do some heavy video editing on
the server side and it works great except that under, what seems heavy
load the below problem happens intermittently.
The problem has only happened 5 times out of over 500 runs by our
backgroundrb worker.
This is the code in our

0.2.0 worker/slave creation
We ran into some problems accessing a freshly created worker, and had to
insert a sleep of 1 second to get it to work. It looks like Ezra and skaar
already know this:
from middleman.rb:
# HACK: there is a race in the worker/slave creation, we
# currently need to sleep between create.
sleep 0.1
You might want to increase it to 1 second for those of us on slowly mac
books.

Recommendations for eternally-running backgroundrb workers?
I''ve got some workers that I want to have running all the time. Right
now I''m just launching them manually, by requesting a special page in
my rails app that includes lines like:
MiddleMan.new_worker(:class=> :receiver, :job_key=>:r,
:args=>{:sleep_time=>10})
This strikes me as a really weak way to fire up my workers. I
basically want to automate things so

Question about new results hash
Is it really a hash? As in, can I pass it into a method that a worker is
calling so that, for example, a method in my ActiveRecord that''s
actually doing the work?
Really liking the new code. Does rubyforge or devjavu have the rdocs
anywhere?

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`.

New Backgroundrb Speed Issues?
The new backgroundrb seemed to me to be markedly slower than the old
one. So, I ran a "side-by-side" comparison test using a worker that
I had written which parses a CSV file and loads the results into a
database. The results? The latest version appears to take twice as
long to run the same code as the previous version. Has anyone else
experienced speed issues with the new

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

send objet between 2 workers
Hi,
I''m using backgroundrb but I have 2 problems with it.
First is when I launch a thread Toto from the do_work method. Toto can''t
access to a class variable defined before... (undefined method `+'' for
nil:NilClass)
I suspect that thread is launched when backgroundrb start but the worker not

MiddleMan.worker blocks?
Hello -
I am observing that calls to MiddleMan.worker return only after the worker
has completed its work. This puzzles me, and I presume that I am doing
something wrong. Can anyone make suggestions?
Snippets from my code are:

constraints = get_constraints(report,start_time,false)

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:
