Segfault with more than 255 sockets about celluloid-io HOT 2 CLOSED

Nevermind, I just noticed that my box has 1.9.2 and not 1.9.3. Sorry :-)

from celluloid-io.

First, nit-pick: Ruby makes your life easy:

255.times do
...
end

As for your actual issue, what happens when you use threads and normal ruby
sockets?

Hey guys! When I run the following code:

#!/usr/bin/ruby1.9.1

require 'rubygems'
require 'celluloid/io'

class Client
include Celluloid::IO
def initialize(host, port) @socket = TCPSocket.new(host, port) end
def read() @socket.readpartial(100) end
end

for i in 0..255 do
client = Client.new("127.0.0.1", 1234)
puts client.read()
end

I get a segfault:

/var/lib/gems/1.9.1/gems/celluloid-io-0.12.0/lib/celluloid/io/reactor.rb:16: [BUG] Segmentation fault

zsh: segmentation fault ./client.rb

When I change 255 to 254, everything works as expected.

Am I missing something or is this is a bug?

Thanks!
Flo
