similar to: Backgroundrb with Load Balancing Rails engines

Hi there, We''ve been using previous version of bdrb (drb based one) for a while and it was running relatively OK. We recently attempted to upgrade to the new version to keep up / use supported version but we ended up reverting to the older version. Here are the things that moved us to revert : 1) With the workers we never manage to pass this error: '''' You have a nil

Hi there, In the latest releases bdrb attempts to load all models during startup routine. We have models that depend on the particular RUBY_PLATFORM but they live in the same models directory. It seems that the inability to load them stops bdrb. Could the models requiring / loading be done one demand, the same as Rails does? thanks, emil

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

Hi Folks, We are glad to announce shiny new release of BackgrounDRb, which will soon become 1.0. A quick summary of changes: - BackgrounDRb is no londer DRb, its based on event driven network programming library packet ( http://www.packet.googlecode.com ) . - Since we moved to packet, many nasty thread issues, result hash corruption issues are totally gone. Lots of work has went in making

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

Hello I''ve been using backgroundrb for a while now and love it. I''ve notices some recent updates and am confused as to which branch/tag is what. What''s the difference between these: new_core/ version010/ version099/ version10/ and trunk, and where does "0.2.2" fit in? Thanks! -- Peter T. Brown peter at wagglelabs.com http://wagglelabs.com

Hi Folks, I am glad to announce 1.0 release of BackgrounDRb. This would be a major release since 0.2 release of BackgrounDRb. Here is a brief summary of changes: - BackgrounDRb is DRb no longer. It makes use of EventDriven network programming library packet ( http://packet.googlecode.com ). - Since we moved to packet, many nasty thread issues, result hash corruption issues are totally

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

Hello all, I get this intermittent error saying OpenURI::HTTPError. At the bottom of the email is what is reported in my backgroundrb_server_<port>.log file. The process_netflix_reviews method is parsing (in the background) Netflix''s RSS feeds. This error also pretty much brings down the BDRb process and to recover, I am forced to do a ./script/backgroundrb stop

I have a big report to produce from a Rails app that takes several minutes to put together. I hoped backgroundrb would be able to pull together all the ActiveRecord stuff in the background then throw it back to Rails for rendering. It seems, however, that I can''t pass an array of ActiveRecord objects from the worker back to Rails. Do I have that right? Another possibility was to do

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.

Hi all, i was using bdrb a while ago and it wasn''t stable enough in version 0.2.1 for doing the job - it loss jobs or did execute only the first one invoked and so on. Now i gave the new version a try and i found a bug at playing around. When i start a worker_method over the normal Unix scheduler bdrb will start as much as possible the worker_method after the :end-time is reached.

I have a BackgrounDRb worker running every 2 minutes. Here''s the basic idea: - events = Event.find_all_pending( 2.minutes ) - while( all events have yet to be processed ) ---- if( Time.now <= event.time_to_process ) ------- fork { process_event } --- end --- sleep( 0.25 ) - end - puts "Done..." Events that need to be processed within the next 2 minutes are loaded and

Hi, I''ve been having some issues integrating bdrb on a cruisecontrolrb server It''s related to the way we stop the bdrb server. The thing is, right now when we stop the process we are killing the parent of the group of the process. This is ok if you''re running script/backgroundrb stop directly from the console, but if I''m running this from another process,

We have a fairly expensive task that we''d rather not schedule too many instances of in parallel. Couldn''t get pool_size to limit the amount of workers, and I figure that''s hardly optimal anyway, so would like to have the work queued up for a single named worker instead, running as soon as possible. Using MiddleMan.schedule_worker() with :job_key does start off a

I have noticed that occasionally (about 50% of the time) when i deploy (using capistrano) my app to a production server, i have to ssh into the box and manually stop and start backgroundrb to get it to load my workers. this is my basic setup i have 2 workers: lib/workers/mp3_worker.rb => takes a hash of params to downsample an mp3 lib/workers/flv_worker.rb => takes a has of

Hi, we are trying to use BDRB for background processing of long-running reports, and have two issues - one is that worker does not see our Report class from Rails, throws a: /var/apps/ror_trunk/vendor/plugins/backgroundrb/server/master_worker.rb:22:in `load'': undefined class/module Report (ArgumentError) from

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 - >

This might be a really simple question, with a simple solution. I have two rails apps running on the same box. Right now I am starting two Backgroundrb servers (11006 and 11007). Wondering if it might be possible to run only one and have the second app point to the first app''s server? TIA, Kit

Hey. I have a very annoying problem, and was wondering what is wrong. Suppose I have backgroundrb running, and then I have an action in some controller. In the action I define a worker. When leaving the action, suddenly the connection to backgroundrb is lost: DRb URI: druby://localhost:22222 Pid: 3976 Autostart... done druby://localhost:42531 - #<Errno::EBADF: Bad file descriptor -
