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

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.

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

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:

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:

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.

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:

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.

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

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

Scheduled workers only run once unless you call self.delete inside the worker
I had a worker scheduled to run every minute with
backgroundrb_schedules.yml:
ebay_runner:
:class: :ebay_auction_worker
:job_key: :ebay_auction_runner
:trigger_type: :cron_trigger
:trigger_args: 0 * * * * * *
This worker posts an auction to eBay from a queue of auctions every minute.
I was having a problem where the worker would run ok the first time, but
never any subsequent minutes

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`.

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

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 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.

right usage of bdrb
Hi,
i''m going to implement a syndication-service, which will get lists in
xml with some meta-data an enclosed video files, which will get encoded
at the end. The syndication run will be startet every five minutes of
a full hour.
So i thought to build 4 Worker. One for checking which feeds to

periodic scheduling
I''ve been using backgroundrb since back in March 2007 or so. It''s
been working mostly OK for me, but since the old version doesn''t seem
to work out of the box with rails 2.0 for me, I decided to test out
the latest version.
So, I''m looking at the scheduling, and trying to figure out the best
option for what I want to do. What I have is a set of workers that

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,

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
