Memory leak and long process problem
I use backgroundrb for many long tasks in my system, but I''m having issues
with one in particular. Two large tasks for me are importing people and
updating companies.

begin
job = ImportJob.find(job_id)
job.process_job

Job Queue
After some initial stumblings, I think I''ve got the hang of
backgroundrb. It''s great! I''d been thinking for many many months how
cool something like this would be!
I''m trying to make a "job queue". That is, a pool of worker threads
monitor a queue. When a job appears, one of the workers grabs it and
executes the task. When complete, the worker

mapping column names in legacy schemata
I have a legacy MySQL database with a weird naming convention - all
table and column
names have a prefix ''_'' , which is annoying, and some of the column
names are misnomers.
I would like to apply a pre-defined mapping between MySQL column names
and method
names to be used in the Ruby class, without having the original column
names being visible anymore.
how can I pre-define a

JOIN conditions
Hi,
how can I get Rails to generate SQL queries with conditions in the JOIN clause?
What I would want is:
SELECT * FROM people p
LEFT OUTER JOIN jobs j (p.job_id = j.id AND j.salary > 9999999)
I tried
People.find(:all, :include => ''jobs'', :conditions => ''jobs.salary > 9999999'')
but that generates
SELECT * FROM people p

thread_pooling sleeping
I''m trying to run a single worker that could perform a periodic task
for a given user.
>From a controller, I imagine something like:

MiddleMan.ask_work(:worker => :foo_worker, :worker_method => :perform_task,
:data => { :user_id = current_user.id })
end
def check_job
@status = MiddleMan.ask_status(:worker => :foo_worker)[current_user.id]

A new QueueWorker class
Hello all,
I''ve come up w/ a worker class that manages queued jobs using a fixed
number of child workers. Well, that''s not quite true -- a new worker is
spawned for each job, but you set the total number that may exist at once.
There are three components:
1) queue_worker.rb: The singleton worker that manages the child workers.
You probably want to auto start this. Make sure you

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

Better rails way to join tables?
Hi,
I''ve figured out how to join tables using :joins, but is there a more
elegant way to do this using built-in rails methods?
Here is the code:
Hiringstep_Job.find(
:all,
:joins => ", hiringsteps",
:conditions => ["hiringstep_jobs.hiringstep_id = hiringsteps.id AND
job_id = ?", 1])
Thanks,
David

mySQL 5.0 upgrade - incompatible DateTime format?
I''ve upgraded to mySQL 5.0, and it''s gone pretty smoothly except that on
DateTime.now doesn''t seem to return a value that mySQL likes any more,
as seen in the following exception:
Incorrect datetime value: ''2005-11-20T15:33:12-0800'' for column ''logged_at'' at row 1: UPDATE notes SET `due_on` = ''2005-11-20'',

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

Lack of 'LEFT JOIN' in Oracle 8, any patch for theta style (+)
Dears,
Oracle 8 don''t support ANSI syntax with :
SELECT e.emp_id,
e.fname,
e.lname,
j.jobdesc
FROM employe e
LEFT JOIN jobs j ON e.job_id = j.job_id
but only
SELECT e.emp_id,
e.fname,
e.lname,
j.jobdesc
FROM employe e,
jobs j
WHERE j.job_id (+) = e.job_id
JOIN syntax came with 9i.
Anyone patched Rails

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

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

Help creating and using database
I have this problem.
I have a Job table in my db, and each job has many steps (table Step).
Is not possible to know how many steps a job has until it is created. So
when I create a new job I have a problem: I can not have a step_id in my
Job table, because it can be one step or more.
What can I do?
