Hello, on the application that I''m working on, we are using Thin. The server implements long polling and commands that alter its internal state. Connecting to the long poll is a very fast operation, while updating the state of the server is a relatively slow operation. The long poll connection is held open until there is a change to be sent to the connection. Here is my current

Hi everyone, If you subclass EventMachine::Connection and call it outside an EventMachine::run event loop, EventMachine crashes! Example: class Put < EventMachine::Connection include EventMachine::Deferrable HOST="localhost" PORT=8080 def self.request(data) EventMachine.connect(HOST, PORT, self) {|c| c.instance_eval { @data = data } } end #

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.

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 All, I''m currently looking into doing a bit of evented network programming in ruby and i''m currently looking into packet, eventmachine and rev. The problem is that I need to be able to fork and start a new reactor within the forked child (it also should open a socket and write status information back to the main process). I have not been able to do this with EventMachine.

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

Hi EM Gurus, I''m hoping someone can shed some light on the following... I''m using a 3rd party (legacy) server that can accept up to 8 simultaneous connections on one port. I''ve been able to make multiple connections to this server from within one call to EventMachine::run {...}. Specificaly, I can access each connection separately using: em_thread = Thread.new do

Hello, First of all I''m new to working with sockets, so the problems I''m having are probably because of my lack of understanding. What I''m trying to accomplish is to create a mac os x client gui to ruby-debug. When a application that includes ruby-debug is started, it starts listening for 2 connections; 8989, 8990 The connection is made by calling the connectToApp

Guys, Just for fun, I tried to see (I know, a silly way to test it) how much overhead we have calling the C functions of the extensions. the benchmark script and the results: http://pastie.caboo.se/128646 The naive C extension: http://pastie.caboo.se/128647 I compared 1.8.6 (VC6 and mingw builds) against a fresh checkout of ruby trunk. What I understand from that is 1.9 is slower than 1.8

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 am using eventmachine 0.8.1 on windows XP and am having very odd problems. This snippet of code gives the error that follows it. class EchoServer def receive_data data puts data send_data ">>>you sent: #{data}" if data =~ /quit/i puts "quitting" close_connection EventMachine::stop_event_loop end end end

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

Short question: is there way to tell EM to actually send data after send_data call? I''m building a file transferring app. I send Mashal.dump''ed metadata first, and then - the file contents (chunked). I found a silly bug: receive_data() gets marshalled metadata and the first chunk of the file in a single variable. Like that: c1.send_data("meta")

hello, i try to add a speex compression on the TDM Talkthrough on the BF-533 EZ-KIT LITE but when i compile i obtain the following errors: [Error li1021] The following symbols referenced in processor 'p0' could not be resolved: 'speex_bits_destroy [_speex_bits_destroy]' referenced from 'Debug\Process_data.doj' 'speex_bits_init [_speex_bits_init]' referenced from

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

Hi all Is the EventMachine website (www.rubyeventmachine.com) down? I can''t access it from South Africa, and have tried using tor as well with no luck. I''m kinda new to EventMachine, so I first have a lot of examples to work through and reading to do before I start pestering the mailing list with questions. Thanks to everyone who partook in creating the library, so far

Hi, list Now I am coding for one non-blocking httpclient based on event-machine, and it seems the client will hang for 50 seconds if the destination is unreachable. My questions are 1. How can I short the timeout? I had tried conn.set_comm_inactivity_timeout(5), but it didn''t work 2. How can I add TimeoutHandler to the connection? Thanks! /Jack -- Jack Tang Software

Friends, I am writing an event system which has an interface on a web site which can create events. The creation of events opens up EventMachine::run and connects to the event server, and sends messages. The problem comes if this is run inside of say, event driven mongrel, where it will crash fatally, the same as: EventMachine::run { EventMachine::run { } } The only solution that

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 using the current release branch from the repository (version_0) on freebsd 6.1 with ruby 1.8.4. This is the error that is generated when running the code below at the bottom of the message, plus a gdb bt.
