Hi Folks, I have been working to fix BackgrounDRb memory usage as such. Ruby1.8 GC isn''t fork friendly and it seems to use a lot of memory because when you fork, it sets a bit in all the objects in global scope which causes OS to all pages in child process. A classic solution is to use fork and exec, rather than just fork. Its working and pretty stable, but you loose ability to pass

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

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

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: def start_job 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] end

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

What does the method query_all_workers() do? There is no documentation on what this method returns (1.0.1 version). Orion -------------- next part -------------- An HTML attachment was scrubbed... URL: http://rubyforge.org/pipermail/backgroundrb-devel/attachments/20080118/9f9b8112/attachment.html

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

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

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`.

I have a worker which wants to delete itself after it finishes its work- how can it do that? Best Regards, Danny Burkes

I''m checking out backgroundrb for a calculation process I estimate will take 2-3 minutes and be ran on-demand only via Rails. Very easy and slick. But I have a question. The connections never close, if I do a netstat they just keep piling up. Do I need to do some housekeeping somewhere? I noticed the @ connection.close statements are commented out in favor of a # FIXME type deal.

Hemant We''ve continued testing our application with backgroundrb and found a couple of other problems when transfering large amounts of data. Both of these problems are still present in the github version of code. The first problem is an exception in the Marshal.load call in the receive_data method in the Packet::MetaPimp class. The root cause is in the BinParser module, in the arm of

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

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

Hi, Is it possible to start a worker with job_key and then ask_status of that specific worker with the job_key? MiddleMan.ask_work(:worker => :auth_worker, :job_key=>''1'', :worker_method => :auth) and then MiddleMan.ask_status(:worker => :auth_worker, :job_key=>''1'') >From my testing of the new backgroundrb, asking status using job key

I''m getting the following error (when doing script/backgroundrb start) on my local machine, which is running os x 10.4.11. However, it works just fine on my linux server. RAILS_ROOT/vendor/plugins/backgroundrb/lib/../framework/nbio.rb:64:in `dump_object'': undefined method `write_nonblock'' for #<UNIXSocket: 0x135b5f4> (NoMethodError) I just grabbed the

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

I use BDRb to process RSS feeds for users on my site (http://feedflix.com). I have a batch job that queries the DB for records that haven''t been updated in the last so many hours and kicks off a background job for each of them. If N records are returned by the DB, N background jobs gets queued and get done serially. As long as N is 255 or under, everything works like a charm.

When I call ask_status on a worker that has not been started I get and exception of type BackgrounDRb::BdrbConnError, which is fine. I can deal with that, but I also find that the backgroundrb process dies as well. The scenario is simple: Call ask_status on a worker that is not auto loaded. I used a job_key, in case that makes a difference. -------------- next part -------------- An
