Couple questions on BDRb and concurrent processing
My Rails site uses BackgroundDRb and I have a couple of questions:
1. Can someone point me to some sample code/examples for how to use
thread_pool? The website doc says to add a line
======
pool_size 10
======
in my Worker class which seems straightforward.
I wasn''t able to understand this part though:
=========
thread_pool.defer(wiki_scrap_url) { |wiki_url| scrap_wikipedia(wiki_url) }

register_status for excess thread_pool?
Hi,
Newbie here. I''ve got a worker (for generating PDF reports) that
uses the "thread_pool" to allow processing multiple reports
simultaneously and queue up any requests that exceed the thread
pool (pool_size = 10 currently).
def process_pdf(user)
thread_pool.defer(user) do |user|
makepdf(user)
end
end
My question is: I use a mutex to handle

Thread_pool bug?
I have a previous question regarding long tasks and the thread_pool (sorry
for the dup, I didn''t see the first go through). To try and track things
down, I made a change based on a suggestion found in the archives. I moved
my import contacts worker to its own file and set the pool_size to 1.
class ImportContactsWorker < BackgrounDRb::MetaWorker

Defer multiple methods within the same worker to the thread pool?
Within a threaded worker, I would like to have multiple methods. Will
the following code work?
def method_1(args)
thread_pool.defer(args) do |args|
#work
end
end
def method_2(args)
thread_pool.defer(args) do |args|
#work
end
end
. . . or, should I have one "meta"-method and pass which sub-method
to perform via args?

failed to find slave socket - (RuntimeError)
Hi everyone,
I''ve a class that try to spawn two workers, every 5 seconds.
The code is something like:

=> :researches)
MiddleMan.new_worker(:class => :products_worker,:job_key => :products)
sleep(5)

thread_pooling sleeping
I''m trying to run a single worker that could perform a periodic task
for a given user.

:data => { :user_id = current_user.id })

def check_job
@status = MiddleMan.ask_status(:worker => :foo_worker)[current_user.id]

Memory leak and long process problem
I use backgroundrb for many long tasks in my system, but I''m having issues

Cannot start workers in production mode

Repeatedly dying with "failed to find slave socket"
I''m struggling to keep backgroundrb v2 running for more than 24
hours. It appears to be running fine for a while, then tries to fire
off a worker (exactly the same worker it''s been running for the past
few hours), and it suddenly dies. I haven''t found any pattern for the
cause of this.
In backgroundrb_server.log, the final entry is this :

Drb Connection error on multiple dispatch.fcgi ''s
Hi All,
I''m using Backgroundrb as a general purpose long-running-task back-end
(upload processing, email sending, etc), and it''s been a great solution.
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

Threadpool and queuing of tasks
I recently switched over to v1.0, and things are rolling along pretty well.
However, one thing that has always been a little confusing to me is knowing
when to use thread_pool. Since most of my bgrb workers are called from my
web app to process rather than being scheduled, I''m using the thread_pool
for every call. Unfortunately, that means that I have to split up workers
by how many

adding results from threads to a collection and returning it
Forgive me if this has been addressed somewhere, but I have searched and
can''t come up with anything.
I am basically trying to distribute several web page scraping tasks among
different threads, and have the results from each added to an Array which is
ultimately returned by the backgroundrb worker. Here is an example of what
I''m trying to do in a worker method:

Polling is REALLY slow
I''m having some trouble with using brb for polling for work. Basically, what
I want to do is update the state of a record and have brb notice and start a
process. I do not want to call ask_work for each process because there may
be several places where the object''s state is changed, and I only want to
process once. Plus, I can schedule things better this way. My first

Scheduled worker dies after about 30-45 runs
I have a scheduled worker that runs every minute, checking for new eBay
auctions to post. If it finds an auction, then it posts it. If there are no
auctions in the database that are queued up, it simply does nothing. I got
the worker to finally run as a scheduled worker, every minute. However,
after about 30-45 scheduled runs, it simply stops running.

: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

mocking a few things in the test helper
When using the provided bdrb_test_helper, I was getting some undefined
methods (register_status, thread_pool, etc) in unit tests. The README
says to go ahead and stub out methods that need it, and send the patch
to the list, so here it is (attached). Also, the MetaWorker initialize
method was written as "initializes", causing the @logger never to be
set, causing undefined method errors

"Text is not a module"
Hello all,
After upgrading to Rails 1.2.2, I''m getting a strange error when one of my
workers is invoked. The worker is responsible for monitoring a folder
(using directory_watcher) and emailing a specific user when a file is
dropped there, but it''s bombing immediately upon instantiation (or maybe
when trying to instantiate ActionMailer?) with the error "Text is not a
