My Rails application requires a very busy worker process running in the background at all times. I am launching this non-interactive process using script/runner. This process is very busy and is communicating with the MySQL server constantly. As I started putting some load on the system to test, I started running into performance issues. I have since discovered that Rails is only using 1

Hi there, I''ve been experimenting with implementing BackgroundDRb in my rails app but am running into some problems. The primary problem I''m getting is in cleaning up worker threads, or getting any kind of response out of worker threads. If try using the response function/hash in my Worker the worker will not execute reporting that response is an unknown variable or function.

Hello all, I''ve been learning Ruby and playing with a chat server I built using GServer. After into an issue I found with GServer, that no one else seemed to notice (actually, similar to this question, GServer is hard to kill nicely, especially when you want to.), I found references to EventMachine, and rebuilt my server using it. I much prefer EventMachine''s model. The

I''ve actually found a way to make EventMachine listen to events from a serial port, but only by using the pure Ruby version, using Guilliame Pierronnet''s Ruby/SerialPort library. It turned out to be simpler than I thought it would be: require ''serialport'' $eventmachine_library = :pure_ruby require ''eventmachine'' module EventMachine class

I''m creating a message queue system, (think JMS message queue) Basically, I''ll be firing off an http request as soon as a row appears in a database. Now in past implementations I''ve done the following. 1. Polled the database every 0.10 seconds. 2. If something was there to work, I''d tag it as complete. 3. Create a separate thread. (no further database hits

Hi devs, I was trying to open a new ticket with a minor doc patch at the BackgroundDrb Trac (http://backgroundrb.devjavu.com/) and it seems like only admins have permission to do so. Is this intended? I read in the readme that patches should be mailed to this list, but I much prefer to use Trac since there''s already one set up. Any reason Trac is not open to registered Devjavu users?

My Rails site uses BackgroundDRb and I have a couple of questions: 1. Can someone point me to some sample code/examples for how to use thread_pool? The website doc says to add a line ====== pool_size 10 ====== in my Worker class which seems straightforward. I wasn''t able to understand this part though: ========= thread_pool.defer(wiki_scrap_url) { |wiki_url| scrap_wikipedia(wiki_url) }

I am trying to run Soul of the Ultimate Nation on a macbook pro and im not sure how to get it to work. Can anyone help me out? Here are links to the websites. You have to install the reactor for the game and the reactor itself. I was able to install the reactor, but I wasn't able to sign in. Anyone have any hints? sun.ijji.com (this is the site for the game) www.ijji.com (those are the

Greetings! I could use some advice on which version of BackgrounDrb to use in my current situation. I''ve implemented the initial, single-process multi-threaded version in a previous site, but have no experience with the new version. Current situation is as follows. The application involves personal health information and so has very stringent session management requirements. My

Yo'z, new here and all, and rather weak in the knowledge department of linux/ubuntu and wine. I'm fairly sure i'm running the latest wine, i installed / updated wine and all that stuff about a month ago so yeah. I'm basically trying to use Ijji Reactor, but it won't let me sign in at all. I don't know how to get the wine log and all of that @_@;

i''m having some problems getting a simple example going with backgrounDRB. after i set my worker to work i try to get back the result like this: w = MiddleMan.worker(key) w.items comes back as DRb::DRbUnknown (i have items as attr_reader in my worker and access it inside there with @items). the result is actually activerecord results in an array. when i change it so my worker puts

Hi, I am trying to run Mongrel on win32 to serve an internal rails application. We are accessing legacy data, and some transactions can take 5 to 10 seconds. This is holding up every other request. The -n does not seem to be supported on Win32. Am I missing something, or should I look elsewhere to serve my Rails app on win32? Thanks, Walt -- No virus found in this outgoing message.

Here''s a gedanken experiment for those w/ far more knowledge than I about ActiveRecord, etc.: Let''s say my database is very remote and on a very slow machine. Let''s further say that my app has an action that leads to a very simple insert into the "impressions" table of the db, a la "INSERT INTO impressions(docid) VALUES($docid);" - and

I change a lot of my CD to Ogg to be able to listen them easily from my computer (I use foobar, I was used to WMP but it does not support library for Ogg files and plug-ins I found for this where poor) without the need for frequent CD changing. I like my music to be richly tagged. But with classical music CD it is a real pain to tag those files. Typical problems involve: - single CD

I have an action in a controller that generates and returns a custom png-file, it goes something like this: def custompng #1 gather some userdata from params. #2 make a system call to an advanced java application that renders a png based on the custom data. stores the png on disk. #3 read the png into rails #4 send the png to the browser with method send_data #5 delete the

Hello, I have been looking at the Ruby/EventMachine. First let me say it look very good. Reactor model with no threads makes for fast reliable server, and I have read about marvelous Twisted framework for Python and am glad to see something similar for Ruby. I am writing network app with Ruby threads now and it very slow, and I try new Ruby 1.9 with native threads that make it much slower.

I''m tracking performance on the machine I installed yesterday. mutt running on one Xen instance, accessing via imap to another instance, accessing via nfs the maildir in another instances, seems little laggy when moving up and down the message index list. Network latency seems low < 30ms on average. So I was tracking vmstat. On the mutt instances is seems reasonable: [nic@shell:~]

If you''re in a timezone with an abbreviation that map to more than one timezone (eg, CST), first_run may not work as you expect it to. Witness: $ irb -r time irb(main):001:0> Time.now => Wed Oct 04 20:37:24 CST 2006 irb(main):002:0> Time.parse(Time.now.to_s) => Thu Oct 05 10:37:30 CST 2006 Notice the 14 extra hours... Time.parse converted the time thinking CST meant -06:00
