How can I add TimeoutHandler to EvenmentMachine
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!

Having very odd problems with UDP.
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

epoll increasing latency big time
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

get_peername - start_server vs. connect
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

Unable to delete epoll event
I occasionally get a fatal error
unable to delete epoll event: Bad file descriptor
I think the attached patch will fix it.
The patch does two things:
1) changes the error we look for from ENOENT to EBADF. It is hard to
reproduce this error, but if I change the epoll_ctl line to
epoll_ctl(epfd, EPOLL_CTL_DEL, 666, ed->GetEpollEvent());
it does return -1 with errno = EBADF on my Linux 2.6.9

Core dump using sample DumbHttpClient
I''m using the current release branch from the repository (version_0)

when running the code below at the bottom of the message, plus a gdb

help anyways.

EventMachine::run - How can I ensure that this
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

Multiple EM connections on separate threads
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:

Crash occurs where EventMachine.connect is
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 }
}

Status of EventMachine.fork
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.

How to send data,
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

Using EventMachine to listen from non-network
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

Gracefully stopping EventMachine?
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.

Testing event driven Socket classes
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:

processes die with:

Interfaces for accessing SSL/TLS certificates
Hi everyone. Does anyone have any preferences or ideas for an interface for
SSL certificates, both client-side and server-side? At present, the only
interface is EventMachine::Connection#start_tls, which uses a built-in
self-signed cert on the server side. On the cilent side, it accepts any
well-formed cert (that is, it doesn''t check that the remote cert is signed
by a trusted authority).

EventMachine website down?
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

ANN: EMDRb 0.1.0
I am pleased to announce the release of EMDRb version 0.1.0, a
rudimentary implementation of a distributed Ruby server based on
EventMachine. It''s available on Rubyforge at
http://rubyforge.org/projects/emdrb but I must admit that it has thus
far only been lightly tested and still a bit feature incomplete. The
server implementation can already do all of the basic stuff one expects
