Get "some read error" on calls to worker
I''m running the latest from svn (rev 285). I''ve been having a problem
launching a process repeatedly. What happens is that I get a debug
message "some read error" and then the worker refuses to run again.
I''ve stripped my worker down to just doing a puts and it still happens.
Like the other threads I want to launch my workers as needed, however I
get the

I am glad to announce 1.0 release of BackgrounDRb.
This would be a major release since 0.2 release of BackgrounDRb.

Query All Worker
What does the method query_all_workers() do? There is no documentation
on what this method returns (1.0.1 version).

pre-release version of backgroundrb available now from svn
Hi,
A pre-release version of backgroundrb is available now from svn.
Download it from here:
http://svn.devjavu.com/backgroundrb/branches/version099/
Since this release marks significant migration from existing
practices, i intend to keep trunk untouched for a while.
There are no install scripts, but you should copy "backgroundrb" file
from script directory of plugin to script

How you want BackgrounDrb to behave
Hi,
Ok, As i promised.. I am working on new version of BackgrounDRB, which
is getting close and will be out soon. I need some feedback from you
guys. So, please reply back.
The code has changed significantly and its no longer using DRB. But I
will keep the name BackgroundRb. Ok, in new API, a worker looks like
this:
require "net/smtp"
require "guid"

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

[PATCH] x 2 - Fix for "null pointer exception" when ask_status is called before worker is run, and docfixes
Sorry for attaching patches in emails to the mailing list, but I''m still
unable to login to Devjavu for Backgroundrb (I''m able to login just fine for
Merb''s Devjavu and submitted a ticket successfully).
Anyway, I encountered a bug when trying to #ask_status of a worker before
it''s run (or rather, before its result_hash has been set to something). Not
sure why

reload_on_schedule
Hello,
Does reload_on_schedule force the worker to be reloaded even if it is
already running?
Or does it just load the worker if its not running when the schedule fires?
I want to load the worker at the scheduled time if its not running, but I
don''t want to reload the worker if its already running.
Make sense?
Thanks,
Scott

Problems sending large results with backgroundrb
I''m working on an application that does extensive database searching.
These searches can take a long time, so we have been working on moving
the searches to a backgroundrb worker task so we can provide a sexy AJAX
progress bar, and populate the search results as they are available.
All of this seems to work fine until the size of the search results gets
sufficiently large, when we start

workers cleanup
Hi,
I''m using backgroundrb 0.2.1 and having problem with worker processes
staying around when the rails application does not explicitly delete
them.
Is there a way to automatically delete the worker processes when it
has completed the job?
Also does killing the process manually (using kill command) harm the
backgroundrb server? I have some occasions where the backgroundrb
server just

Updates and Fixes on Trunk
Hi,
I am pushing some updates and fixes that addresses much of the issues
that we talked about since last couple of days.
1. Use configuration option :debug_log: false to disable
backgroundrb_debug.log.
2. As shown below, use lazy_load option to disable aggressive loading
of models ( and somewhat stupid too).
3. MiddleMan.delete_worker(:worker => :foo_worker) will now ABORT the

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`.

Why the switch to SMTP
Can anyone explain why BackgrounDRb is switching form DRb to SMTP
protocol? That seems like a lot of overhead to add to the messaging
back and forth?

Problems with async worker request
Sorry if this comes through twice. I already sent this once, before joining
the mailing list.
I''m attempting to use Backgroundrb to handle asynchronous pdf creation, but
in doing so, I''ve run into a very strange problem. Below is a method that''s
called from the controller which creates a new worker, then grabs the worker
and calls the ''build_pdf''

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

Backgroundrb 1.0.1: uninitialized constant Packet::ClassHelpers (NameError)

Can schedules START a worker?
Hi there,
I''m just working on getting backgroundrb (1.0.1) up and running. I''m no
expert with ruby, etc, so I still don''t quite get a few things.
I have scheduled workers that run every few minutes. That works fine. I
have other workers that run once per day or even once per week. It doesn''t
make sense to have them running all the time. I''d
