There appears to be a problem with sending 0-length (UDP) datagrams. I have a little UDP server running on port 1392, and when I execute the following client code the server does not receive anything. However if I change it to data="x", the server receives it just fine. EM::run { conn = EM::open_datagram_socket( "", 0 ) data = "" puts

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

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 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 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 #

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

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

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. Sorry no debugging symbols built into ruby but maybe the bt will help anyways. terminate called after throwing an instance of ''std::runtime_error'' what():

Francis, I read in the list archives back that a future EventMachine release will support epoll on Linux (i.e., it''s in the trunk). Better still, is there a possibility that EM will rely on libevent so that it will be architecture independent (i.e. epoll on Linux, kqueue on FreeBSD/Mac OS X, /dev/poll on Solaris)? This is how memcached is implemented, and it would be helpful to be able

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

Sorry this is going to be a bit vague, but I''ve noticed something rather odd going on with EventMachine on Linux. I''ve written something uses EventMachine to proxy HTTP to other processes. On OS X, it works great, adding only about 20% extra latency into the connection when proxying versus connecting to the original backend process directly, so a 5ms connection might now take

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

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

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.

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

Hi, On windows, get_peername works both with connections obtained via start_server, and connections obtained via connect. On linux, get_peername seems to only work with connections obtained via start_server. (I''m using svn HEAD.) I''m wondering which is the intended behavior? (I realize get_peername is less useful for connections obtained via connect, since one should already

The following program is a minor variant on the sample given in the README with eventmachine-0.8.1. I am running under CentOS 4.5 (kernel 2.6.9-55.0.2.plus.c4) with a ruby-1.8.5 RPM from the CentOS testing repository. When I run it, I find that set_comm_inactivity_timeout doesn''t do anything. That is, if I client opens a connection, it stays open indefinitely. However, if I comment out

Hi , I am writing a rake task to consume twitter stream API. The task contains the following code: consumer = OAuth::Consumer.new(CONSUMER_KEY, CONSUMER_SECRET, :site => ''http://twitter.com'') access_token = OAuth::AccessToken.new(consumer,ACCESS_TOKEN,ACCESS_TOKEN_SECRET) oauth_params = {:consumer => consumer, :token => access_token} EventMachine.run do # now,

Ok, here is the class, I want to Unit Test, its part of a large app and is based on EventMachine library. I want to mock the class TickServer ( i.e not stub it) . Since in actual scenario, you can''t do this on this class: @server = TickServer.new # will toss an exception at your face you must initialize the server like this: EventMachine.run {
