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

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():

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

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

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 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).

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.

Just thought I''d let you know that your http parser worked great for creating an http protocol handler for Eventmachine. It wouldn''t take that much effort to use Eventmachine for Mongrel, might be worth a shot just to see how it does. A few things would need to be restructered, like HttpRequest where you read the rest of the body, and calling the handler. But it

Is getsockname (or its equivalent) available to an EM Connection object? I''d like to access the local port number in my client application. --Michael

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

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")

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''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

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

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

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

Hello everyone, I am testing Dovecot 1.1.3 at the moment to see if I can migrate from UW-Imap(mbox) to Dovecot(maildir). Because I dont' want to influence the production server I installed Dovecot on an ununsed computer with some dummy-testusers using ssl and maildir. Installation was without any problems and everything works fine with one exception: I cannot download some attachments.

I made a quick patch to em so it will try to read the key/cert from a file if it exists in the cwd, and if not use the hardcoded default. If I added a function in rubymain.cpp to set the location of the pem file, where in em would be the right place to set it? It should be in the same scope as start_tls I would think. I''m checking for the pem file in InitializeDefaultCredentials().
