similar to: Access worker outside of Rails?

Friends- I''m happy to annouce the first alpa release of BackgrounDRb. This is a small framework for managing long running background tasks that allows for ajax progress bars and more. It also serves as an Application wide cache and context store for when you need something like sessions but shared between users and multiple backend processes like fcgi''s or mongrels.

In response to my Rails Weenie post today[1], someone mentioned that I try BackgrounDRb to help take the strain off my application. 1: http://rails.techno-weenie.net/question/2006/7/13/nested-loops- best-way-to-send-messages-to-blog-subscribers I''ve just tried to install and use BackgrounDRb with my app, but I''m afraid that I''m not too versed in running processes

Hey there bdrb''ers! I have been so very busy with http://engineyard.com that I have not had time to complete the new release of backgroundrb. But I have done substantial work towards it. It is basically an entirely new beast with a complete rethinking of how it works. I have put up a zip file of the new code base in the hopes that some folks will be able to start playing with

Hi Ezra, Thanks for the great work on BackgrounDRb. I have come across a couple of problems. 1. I wanted to define a simple class in the worker file to wrap up and pass back some data to my controller. It seems that if I create the class either inside or outside of my worker class (in the same file) it gets wrapper by a DRb::DRbUknown object and therefore cannot be accessed from my controller.

Hello, I am trying to make DRb calls to a external server from a backgrounDRb worker, but I''m getting always the next exception when I make the remote call. > ERROR: > drbunix:///tmp/backgroundrb.11175/experimenter_worker_3e899de945f0803a82cd257cfac316d0_0_0.0738904928422051 > - #<Errno::ENOENT: No such file or directory - >

OK I know whats happening. Your while loop completes and calls kill on the worker before your task_progress controller method ever gets called> So the worker is deleted and when you try to access it from rails you get an error because there is no longer a worker at that job key. The kill method is meant to be used within a worker that you fire and forget. If you want to get the

I just updated backgroundrb to the latest version, and now I get this: uninitialized constant MiddleMan /usr/local/lib/ruby/gems/1.8/gems/activesupport-1.3.1/lib/ active_support/dependencies.rb:123:in `const_missing'' /usr/local/lib/ruby/gems/1.8/gems/activesupport-1.3.1/lib/ active_support/dependencies.rb:131:in `const_missing''

Hi. I thought that BackgrounDrb was the perfect solution for my long running report production tasks. But I can''t seem to get anything useful back out of it. I set up a simple test worker that just does class TestWorker < BackgrounDRb::Rails attr_reader :pupil def do_work(args) @progress=0 @pupil=Pupil.find(3) sleep rand*10 @progress=100 end when I try to

Hello, Yesterday I posted about how to email from a worker. I decided to be a bit piggy and just inhale all of rails. Sorted. I am noticing some rather ominous behavior though. The setup: My worker takes an uploaded image as a param and passes it (via system call) to a C++ image processing engine. Take a look at these memory consumption figures for successive runs uploading the identical image

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: -------------------- controller app/passwd/index -------------------- class Passwd::IndexController <

I searched a bit, but have come up short. Are there any libraries for creating popup forms w/ rails? These would not be displayed in a separate browser window, but rather made visible over an open page and adjacent to a clicked link -- similar to the google maps baloons, or the gmail popups. Lots of other examples out there... Thanks --------------------------------- Talk is cheap. Use

I''m looking for a good way to search a few fields accross multiple asociated tables (i.e. find ''friends and family'' accross Photo.name, Photo.description, and Tags.name where Photo has_many tags). And, ideally there''s a competent query analyzer/parser. I''ve expirimented with constructing my own SQL using ... LIKE %term1% ... etc, but the

I''m working on upgrading my app to the latest version of backgroundrb. Everything went find until I tried to execute my tasks. Here is my simple worker for testing: class MscWorker < BackgrounDRb::MetaWorker set_worker_name :msc_worker def create(args = nil) # this method is called, when worker is loaded for the first time end # Send a message to everyone def

Calling url_for_file_colum results in a TypeError: can''t convert nil to string. The error is in line 148 of filecolumn.rb: def relative_path(subdir=nil) File.join(relative_path_prefix,subdir, @filename) end If I substitute '''' for subdir in the File.join command, then it seems to work fine. Since this is a plugin, I''m wondering why I need

got a wierd problem maybe someone can help with. whenever i try to pass an array or AR objects to my worker, i end up with a DRb object in the worker...here''s an example class SearchWorker < BackgrounDRb::Rails attr_reader :resources def do_work(resources) logger.info resources.inspect end end class SearchController < ApplicationController def start_search

Hi, I have a question regarding RoR and DRb. First of all, I tested with simple client/server examples and everything worked as expected. I have the following lines in my environment.rb: DRb.start_service $rem_obj = DRbObject.new(nil, "druby://#{rname}:9001") Since rem_obj is a global variable, I can call it from any controller and the invoked procedure is run on the server. However,

I'm expirimenting with Cepstral via swift.agi. It loads w/ no problem, but there is a fairly long separation between words -- almost as if it is processing one word at a time, rather than stringing a phrase together. When I run cepstral with a similar script, but not through an actual call from asterisk the separation between words is short and natural. I'd really appreciate

I''m developing a stateful Ruby application that needs to keep data in one location where all people accessing the site can modify its contents. This data will be read-from/written to often, so I would prefer for rails to keep it in memory, rather than a database. My frist try involved global variables. After discovering that they were being "re-initialized" with each new

Hi, I'm wondering if this code from the "Writing R Extensions" manual is really safe: SEXP mkans(double x) { SEXP ans; PROTECT(ans = allocVector(REALSXP, 1)); REAL(ans)[0] = x; UNPROTECT(1); return ans; } double feval(double x, SEXP f, SEXP rho) { defineVar(install("x"), mkans(x), rho);
