Folks- I just pushed out a new release last night. THis is a bug fix release as well as some new features that have come up that people need. I made the MiddleMan class include Singleton so it is now a true singleton. What this means is that the autostart stuff now works correctly because you can always get the same MiddleMan instance from anywhere within the drb server including your

Hey Ezra, I asked this on ruby-talk, but probably you missed it. I am already using Backgroundrb for several other stuff. But i am curious, that how it will work with rubyinline? Ruby threads, should handle it alright..theoretically(since backgroundrb uses ruby threads) But, i would just ask opinions of Ezra on this. Because i feel, stuff at my end needs some real optimization. These worker

Hi, I am getting my hands on trying the cool BackgrounDrb plugin. Following various discussions and suggestsion, I included "include DRbUndumped" in my ActiveRecord model. However, the following exception occurs after I tried this and hit the page that uses this model. Does anyone know why this is so? Is it possible that an object cannot be DRbUndumped (that would mean, we

Hi there, I''m trying to create a worker to do some asynchronous web client work and update the data model with its results. It seems, however, that every call I make to an ActiveRecord subclass causes the whole thing to block. At least I think it''s blocked. Right now I''m just using debug log output. Is there a decent way to debug/test workers I can try? Is there any

Hey Greg- Yes I am sorry, the new architecture uses fork and named pipes and a bunch of unix stuff to do its magick. Now you may be able to port it to qwork on windows, but I don''t think it is possible :( I''m really sorry about this but I need this thing to be as robust and solid as it can be and in the end windows isn''t compatible. Now you may be able to

I had a worker scheduled to run every minute with backgroundrb_schedules.yml: ebay_runner: :class: :ebay_auction_worker :job_key: :ebay_auction_runner :trigger_type: :cron_trigger :trigger_args: 0 * * * * * * This worker posts an auction to eBay from a queue of auctions every minute. I was having a problem where the worker would run ok the first time, but never any subsequent minutes

We ran into some problems accessing a freshly created worker, and had to insert a sleep of 1 second to get it to work. It looks like Ezra and skaar already know this: from middleman.rb: # HACK: there is a race in the worker/slave creation, we # currently need to sleep between create. sleep 0.1 You might want to increase it to 1 second for those of us on slowly mac books.

Is there something special I need to do to access session data in a worker? I''m using an AR session store. I''ve been working with Ezra''s tutorial, modifying it a little here and there to figure it out. So I changed the progress bar to a simple count-down in the worker which sends back the count to display in the view. No big deal. But if I try to access session

Hello. I read in an old announcement by Ezra, relating to the older version of BackgrounDRb, about workers being able to clean up after themselves and a TTL feature. I''m not sure if these things are present in the newer version. I''ve tried overriding the delete method in my worker but when I call delete_worker, the method doesn''t appear to be called. Is there a right

Hi the list people, hi Ezra, I just read from this message http://rubyforge.org/pipermail/backgroundrb-devel/2006-July/000134.html that BackgrounDRb will offer a way to kill a worker from within itself. As this message is from 7/25, I wonder if this feature has been added since. If not, is there any way to do it? I tried this: MiddleMan.delete_worker(@_job_key) But it raise: uninitialized

Hi, First off, thanks Ezra for showing the way with BackgrounDrb. It''s a real godsend. I wanted to add a bit of job control to the system so that I could cancel DRB processes and so on. I thought I''d share how I did it in case anyone should find it useful or have feedback. I wanted to be able to put checkpoints into the drb job so that I could let the job do whatever needs to

I am new to this list and relatively new to the backgroundrb plugin,. So first i will say hello to everybody here, especially to Ezra Zygmuntowicz! I played a little bit with a dummy worker and so far everything worked well. But now i want to do real work in a worker but now i get that error[1]. It looks like that the constants configured in environment* configs are not available to the worker

Hi List, first of thank you Ezra for BackgroundRB. Very cool plugin indeed! This is a public service FYI. In case you are running postgres as your database backend and you are seeing the following errors in your backgroundrb.log: ActiveRecord::StatementInvalid: NoMethodError: undefined method `async_query'' for #<PGconn:0x22ed648>: You are using the postgres-pr adapter

I''ve been trying unsuccessfully for the better part of today to write a worker that can use by ActiveRecord model classes. The bizarre thing is that worker just stops at the point accessing the database connection. An exception isn''t raising, it just dies. My worker class is below, I''ve interspersed log messages throughout to try to determine where it is dying. =====

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

Hi *, are there some special settings except of "load_rails: true" to make ActiveRecord models accessible within my workers? I''ve just installed the latest version of this great plugin, but I keep getting undefined method [] for #<DRb::DRbUnknown:0x12345> (line 105 in backgroundrb.rb) when one of the arguments for the worker is an ActiveRecord object. I assume that
