cron like behaviour?
Hi
I have previously used railscron for server-side manipulation of the
database but had a heap of trouble working with it.
BackgrounDRB was suggested to me by a friend.
I upload some files via acts_as_attachment and these go lie in a dir
structure that i desire. What I want from the background process is to
periodically (not user initiated) do some file-structure manipulation i.e. I

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:

schedule support on latest svn, a question
I''m running the latest backgroundrb mainly for scheduled tasks support.
As per the documentation I created the backgroundrb_schedules.yml with
the following:
simple_label:

:worker_method: :do_work
:job: :bleh
:trigger_args:
:start: <%= Time.now + 5.seconds %>

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

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

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

Behaviour of pool_size setting
Hi,
I have backgroundrb running to decouple the execution of massive
business logic from an ActionWebservice request. The service is designed
to take some configuration parameters and fire a lot of background
workers to do the requested work. Due to performance reasons I want to
limit the number of workers to a maximum number of 30. But when I start

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.

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

Scheduler skipping schedules
There is a line in the backgroundrb codebase:
sleep 0.1 # TODO this is dangerous; could skip over some jobs
Could this explain why my scheduler stops triggering?
It only seems to work for about 12 - 24 hours before schedules are
being skipped...
Once I changed the times to using cron trigger in
backgroundrb_schedules.yml and set the times to every 37th and 59th
minute of the hour, instead of

passing arguments to worker method
Hello all,
i just started using backgroundrb and i really like it a lot so far.
I finally succeeded in setting up version 0.21 and the examples from the
readme run fine.
Now i do not want to create and delete my worker anytime i want it to do
something but call repeatedly a method with arguments.
There is a arg_method defined in the readme so i guess this is a feasible
way to procede.

disregard RE: new syntax for autostart and repeat
So disregard this question. I followed Mason Hale''s suggestion that I pass
in some worker_args and all is well in the scheduler.yml file.

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

Passing object into results - "can''t convert DRb::DRbUnknown into Hash - (TypeError)"
Hi,
I''m using backgroundrb to get RSS feeds and pass them back to the
controller. I''m using the Ruby RSS library to parse the feed, which returns
an RSS object. After that I pass the object into the results hash, but
that''s when this error occurs. Basically, this is what I have:
rss = RSS::Parser.parse(response.body)
results[:feed] = rss # error!

rails 1.2.1, locomotive and backgroundrb
Hi
I just tried to move my project to rails 1.2.1 on my locomotive
development setup. It seems that backgroundrb is not willing to start

This is the error I get while attempting to start backgroundrb:

Error after moving to production server
so i have an after_create method on my track model that kicks off a
background process that converts an mp3 to a swf.
this is working fine locally on my machine, but upon moving it to my
production server, i am getting the following error. I''ve only been
using backgroundRB for like 48 hours, so i''m not really sure what
this means or where to go. any ideas?
