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

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 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 #

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

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 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().

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

Hello Mongrel Users, I''m writing a web server called Ebb. It''s written in C, makes use of the Mongrel HTTP parser, and uses libev its event loop. The goal is to be small, fast, and language independent server that can host web frameworks. I have written a small Ruby binding which provides a Rack handler - this will allow Ebb to host Rails, Merb, and other Ruby frameworks. In the

I heard about a new mongrel plugin or version that''s single threaded and uses non-blocking IO with events. It''s called something like "swifty fly". Anyone have a link for it? Thanks.

Hey so, People are asking about Mongrel Ruby 1.9 compatibility. Isn''t the point of 1.9 for library developers to have time to get ready for 2.0? It''s not like 1.9 is a production release. Evan -- Evan Weaver Cloudburst, LLC

It would be an interesting topic. I bet there are quite a few. I just released one that 1/2 runs on Mongrel. http://direxionfunds.com It was released before it was _quite_ ready, but the last of the content is getting inserted today. I am still waffling on how I will leave it running longterm. Right now it uses a slightly modified version of the Mongrel http parser with EventMachine to front

Zed, Do you have a feeling for how Mongrel''s speed has changed since you started out? Just Mongrel with a plain static file; not burdened with having to go through Rails. You initial numbers were substantially faster than webrick. Now that there is a lot more stuff in Mongrel, are they still substantially faster in your benchmarks? Thanks, Kirk Haines

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

Hello Guys, I''m reviewing the code for 1.9, and forgot about this when we first spoke on this subject. The current way we stop threads is using Thread#raise to spread StopServer exception, which will not work as expected in 1.9. 1.9 will treat raised exceptions as #kill, like JRuby does, so the worker threads will not finish serving the client and _then_ exiting, but will be

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 know this error has been reported before, but a couple ppl have reported getting this randomly when running Thin and it crashed the server: terminate called after throwing an instance of ''std::runtime_error'' what(): unable to delete epoll event: Bad file descriptor I think it''s fixed on trunk now so I''m telling people that have this issue to checkout

Dear Mongrel Users, It appears that Francis still isn''t satisfied with my attempts to apologize and he''s now asked me privately to retract my statements. So, just to be sure he finally gets it: I retract my statements that Francis and his friends are "shady" and "desperate for cash". He is in no way a shady guy, having dealt with this situation with the

Hi Mongrels, Anyone used Packet? http://rubyforge.org/projects/packet It''s a pure-Ruby (I think) evented framework. It might offer a nice way forward for 1.9''s system threads, JRuby, and Windows, all at once. Mongrel''s green thread queue doesn''t have a lot of life left in it.

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.

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
