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 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

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

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 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

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 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 , 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,

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

I''ve added experiments/core-model-2 to SVN. I think this is pretty clean and satisfactory. Jeff, please have a look and see if you like the placement of timeouts (which are currently unimplemented). Any event now has the possibility of a timeout. To get an application-level timeout, you''d just post an event with a timeout to a nil target. When the timeout expires, the errback

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

I''m working on StrokeDB* right now and put pieces of networking stuff into a separate repository "Eventmachine utils". There are 3 useful libs already: protocol chaining, messaging protocol and marshalled messaging protocol. Check them out :-) Overview: http://gitorious.org/projects/eventmachine-utils Files:

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 DRb

Hey Guys, I am trying to create a app that makes use of EventMachine. As I recently fell in love with Rspec, I was trying to use it with our EM. However, I have no idea how to do this. Also, I want to remove network connections from the tests (as I might not be connected when running them), so I think I should mock them up, but again... I don''t know how to do this! Any tips? Thanks

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

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")

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 everyone, For those who have/had problems with Webrick not properly closing MySQL connections, there is a new MySQL gem. (Actually the version was released some time ago, just nobody took the time to make a gem) So run "gem update" or just "gem install mysql" to update (not sure if the latter also updates). Special thanks to Tobias Luetke, who forwarded the gem to Chad

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

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
