iodine - HTTP / WebSockets Server for Ruby with Pub/Sub support
License: MIT License
My name is Boaz Segev and I'm:
I'm available by:
My intention is to leave this world in a more compassionate, loving and free state than it was when I entered it.
I am trying to add support for permessage-deflate to do compression of messages sent from server to client.
There is an implementation in https://github.com/faye/permessage-deflate-node for https://github.com/faye/websocket-extensions-ruby.
However, I can not figure out what the appropriate way to add the extensions are. There is some discussion here, but no details on how/if it's possible to get this to work at this time: faye/faye-websocket-ruby#87
Steps to reproduce:
rails new proofofconceptcd proofofconceptrails s &curl -XPOST http://localhost:3000 -> '404'iodine &curl -XPOST http://localhost:3000 -> '500'Results in the following exception:

My Rails application that use Iodine is set to log with STDOUT
config.logger = ActiveSupport::Logger.new(STDOUT)
But I found whenever I use puts nothing is showing to my terminal until the next server restart.
It is because my bad config on the Iodine?
git clone [email protected]:can-i-has-a-job-plz/litecable.git
cd litecable
bundle
IODINE=1 bundle exec rspec
# => Segmentation fault (core dumped)
backtrace looks like

[Current thread is 1 (Thread 0x7f1b4f800700 (LWP 13035))]
but I'm not really sure that it's useful (it's around 8k frames for segfaulted thread). Reproducible here on Fedora-29 x86_64 & on travis ci (some ubuntu, x86_64).
Hey
Does it support listening to custom HTTP method?
A particular scenario requires the HTTP server part to listen to incoming custom HTTP method, specifically NOTIFY and SUBSCRIBE. Whatever data is received, that needs to be transmitted using websockets to a client, realtime.
Since it is mentioned that it can run both HTTP server and a Websocket server, how can we do this, if at all?
hi,
I'm trying to update from 0.3.6 to 0.4.6. Any guides on how to do that? Our application uses WebSockets heavily. We used to upgrade our connection like so:
if env['upgrade.websocket?'.freeze] && env["HTTP_UPGRADE".freeze] =~ /websocket/i.freeze
env['iodine.websocket'.freeze] = WebsocketHandler.new
[100, {"Sec-WebSocket-Protocol" => env["HTTP_SEC_WEBSOCKET_PROTOCOL"]}, []]
end
This was then translated by iodine to 101 Switching Protocols and iodine would add all the required headers for websocket update on it's own.
Sadly this doesn't work anymore, as browser reports 'unexpected response code 100'.
Examples in the readme say now I should use status 0 for the update? This, however, causes Chrome not to recognize the connection correctly anymore, and it seems iodine returns 500 error. I can set the status to 101 and do the update manually but that will require me to set all the other websocket protocol headers as well (Update, Sec-WebSocket-Accept etc).
Let me know what did I miss :)
Hi, I trying your server and have one issue. My web application needs to load a bunch of data about issues so I split to ten or so chunks and made parallel requests. Browser process them in batches of two (send 2 request, wait for response, next two, etc.).
When I run puma with -t 1 -w 4, everything is ok. But if I run your server with same settings -t 1 -w 4, some connections are properly handled and some are failed with empty response. With -t 2 -w 4 everything goes well. I'm really not sure what can do it, but it's definitely not a problem with my application because on every other tested server everything is OK (tested with webrick, unicorn, puma, passenger and thin).
Also, have you done some benchmarks? In my scenario with these issues, I have pretty slow requests in general as you can see, it's because this is a pretty complex application, entities are big and with many nested entities. I experienced that your server has significantly slower responses then e.q. puma (about 30 - 50% slower).
Hi there, something useful to have is the pidfile argument to can kill the main process.
I'm currently using rails server --pid /my.pid but the problem with that is that the port and the bind/socket in the iodine initializer is ignored, and I have to put all the settings in the rails server command (rails s -b /socket -p 0 --pid /my.pid) instead of just iodine =) .
Thanks in advance.
I'm having a great experience with iodine in production in my (small) company and I'm wondering how to extend Iodine to solve an issue we are having. We have some misbehaving (web) clients that ocasionally send a burst of duplicated requests to an expensive endpoint - a server even crashed because of that - and we're looking into a solution to avoid wasting resources with them.
The easier solution is to use something like rack-attack and just drop these requests from misbehaving clients with a 429 error. However, I was wondering if there is a way to implement some request coalescing logic like this to avoid showing an error page when this kind of thing happens. It would have to be implemented either in the load balancer (which is not managed by us) or in the application server. Another way of solving the problem would be inserting another reverse proxy in front of the application like Nginx or Caddy, but I wonder if that would be overkill.
Is there a way of doing some kind of request coalescing / collapsing with Iodine? 🤔
Hi Bo,
This should be an interesting one. I'm not 100% sure this lies in Iodine, but I can't reproduce it with any other server.
Here's the stacktrace:

Moving the assignment of input into the stream block makes everything work, FYI, tho I don't believe that's a legit fix.
Cheers!
This is more of a question, but are there plans for HTTPS/HTTP2 support? I notice in your README that supporting HTTP2 was one of the reasons for starting this project, but then I only notice HTTP 1.1 support.
I was considering adding support via the http-2 gem, but then I couldn't find any information on setting up SSL. Am I missing something in how to configure that, or is SSL not supported yet?
Right now PubSub is very opaque, is there any way for introspection?
For example https://github.com/palkan/litecable needs a method to teardown channel (i. e. unsubscribe all clients), is there any way to implement it using iodine pubsub?
For some reason, each is broken on Linux, while working flawlessly on macOS.
Tests have yielded no apparent reason so far, though it might have something to do with closing connections (and might not).
The error received is "segfault" for address 0x00000....04
Attempting to reproduce with C code (no Ruby) did not yield any errors nor segmentation faults.
The issue is being researched, but is (of yet) unresolved.
Hi!
I found that the server throws strange errors without backtrace in the case when it runs with Sinatra and uses publish \ subscribe for server processes.
Video with the problem reproduction:
https://youtu.be/c5AWvsdX0AE
Repo with test code:
https://github.com/haukot/iodine_issue
Errors are similar to these:
Iodine caught an unprotected exception - NoMethodError: undefined method `call' for "ensure in block in singleton class":String
Iodine caught an unprotected exception - NotImplementedError: method `call' called on unexpected T_IMEMO object (0x000000018bd660 flags=0x405a)
Iodine caught an unprotected exception - NoMethodError: undefined method `call' for "^xml(\\s+(.+))?$":String
Iodine caught an unprotected exception - NoMethodError: undefined method `call' for #<Array:0x000000028494d0>
Iodine caught an unprotected exception - NotImplementedError: method `call' called on unexpected T_NODE object (0x0000000163d778 flags=0x35491b)
Iodine caught an unprotected exception - NoMethodError: undefined method `call' for "/home/haukot/.rvm":String
It seems that the process captures a random memory. Usually these errors don't do anything, and even messages are written to client sockets correctly. But sometimes messages not written, and once the entire server has crashed. This is error dump:
https://github.com/haukot/iodine_issue/blob/master/error_dump
In other cases (in particular, if the Slim template is not used), the server writes errors like this:
ERROR: (pub/sub) cluster message size error. Message ignored.
P.S. It would be really cool if you have any ideas how to show any backtrace in such situations, even if it will be C backtrace. Otherwise it's quite difficult to localize the problem.
currently when using iodine capybara-rspec, ctrl-c does not seem to be propogated properly back to rspec, so the specs will continue to run. if you press ctrl-c again, the tests will immediately stop and not inform the user which tests failed.
it would be great if iodine had the same behavior as puma here, where ctrl-c would be delegated to rspec so it would inform the user which specs failed.
System: mid-2011 iMac, 3.1 GHz Intel Core i5, OS X 10.11.6
Running gem install iodine fails when compiling facil.c, where the constant CLOCK_REALTIME is reported as nonexistent. The discussion on this SO question for an identically-manifesting error eventually converges on a consensus that Xcode 8 is required for that standard constant, and thus OS X 10.12 (which is required to run Xcode 8).
It Would Be Very Nice If the OS X version restriction was noted prominently in the README. It would be even nicer (though unexpected) if anyone has ideas for a workaround that would support those of us thus far unable to migrate to (High) Sierra.
Output from running gem install iodine follows:

The app is totally dead and need to restart. Do you have an idea of how to better debug this kind of problem to prevent it from happening?
First of all, thank you for this amazing project! 😀
I was reading the docs section Running with Rails and then I got confused in this part:
Optionally, it's possible to add a config/iodine.rb file
I wonder how should I tell Iodine to load config/iodine.rb.
I looked up the command line options and I expected to find a flag like Puma's:
bundle exec puma -C config/puma.rbconfig/iodine.rb? Something like this:bundle exec iodine -C config/iodine.rbrails s instead?I'm seeing messages like the following:
ERROR: log line output too long (can't write).ERROR:
I believe this is because of this issue:
Line 184 in d63402b
Any plans to make this allocate on the heap instead? Logging is broken for me in this case (with the hard limit).
If it's too tricky to make it allocate space on the heap when the log entry is too long, then maybe a separate macro for "verbose logging" or something would work?
Hey @boazsegev, hope all is well 😄
We are getting a random segfault after an acceptance tests finish in capybara. I believe capybara may be killing the Iodine thread (which is should do automatically), at which point Iodine sometimes segfaults in fio_flush_all
Here is the backtrace info:

Hi,
This is more of a question than a real issue - I'm running iodine and using it to serve many websockets. In my dev env I've noticed that even if I set processes and threads to 1 (confirmed by iodine output: Running 1 processes X 1 threads) I can still connect more than one websocket to the server. How come? Isn't there a direct correlation between number of threads and number of websockets I can connect?
Not sure if you can debug from just the backtrace, but here it is. I normally only see it randomly after sending SIGINT, where it feels the process is completely not responding.

Let me know if there's something better to debug against (core perhaps?) or if I can do anything to help debug this.
Much thanks!
After updating iodine to 0.7.25, I am now seeing a broken pipe error during rails shutdown.
It's trying to do a puts "Exiting", but stdout is no longer available??

One weird thing is, that looks like an INT handler, but I'm pretty sure we are stopping rails with a TERM signal not INT, so not sure if that is a clue or not.
I'm not sure what changed to cause this to start happening, but I'm seeing it all the time now in both iodine 0.7.25 and 0.7.31. The seg fault occurs immediately after starting rails.

Hi there, I'm trying to test iodine in my env, and I'm having problems in docker (my prod env). Any thoughts in what could I do about that, or if i need to install any extra lib?
Tested in => CodeFresh && locally with Docker version 18.09.0-ce, build 4d60db472b

If you need any extra data just tell me 👍
GraphQL has become a staple in the Ruby community for building APIs. GraphQL subscriptions work on top of GraphQL to add real time data streaming, and has powerful client side implementations such as Apollo.
Currently, the only FOSS implementation for graphql subscriptions in ruby is the ActionCable implementation. Obviously, there is a lot to be desired performance wise from this implementation.
I think Iodine could attract a lot of users who currently have to use the AC version. What are your thoughts on including something like this in Iodine?
I'm not quite sure that it's iodine issue, but I suspect so:
require 'iodine'
require 'net/http'
require 'concurrent'
class ServerTest # :nodoc:
def self.logs
@logs ||= Concurrent::Array.new
end
end
class App # :nodoc:
def call(_env)
ServerTest.logs << 'log'
end
end
Thread.new do
Iodine::Rack.run(
App.new,
Port: '3099', Address: '127.0.0.1'
)
end
Net::HTTP.get(URI('http://127.0.0.1:3099'))
p ServerTest.logs
# => []the same test with puma shows expected ["log"]
As discovered by @jerryshen in Plezi issue#21, iodine conflict with coffee-script.
I have narrowed down the issue to the race between the two gems for child process reaping and opened an issue with the ExecJS team.
For now, the workaround will be to disable iodine's child reaping feature. I'm not happy with the solution, as iodine probably should reap any child process in order to eliminate any zombie processes. However, for now it is out of my hands :-/
Websocket spec says that If the callback handler is a Class object, the server will create a new instance of that class., but according to:
require 'iodine'
require 'websocket-client-simple'
class ClientSocket # :nodoc:
def self.on_open(client)
p client
end
end
class App # :nodoc:
def call(env)
unless env['rack.upgrade?'] == :websocket
return [404, { 'Content-Type' => 'text/plain' }, ['Not Found']]
end
env['rack.upgrade'] = ClientSocket
[0, {}, []]
end
end
Thread.new do
Iodine::Rack.run(
App.new,
Port: '3099', Address: '127.0.0.1'
)
end
WebSocket::Client::Simple.connect('ws://127.0.0.1:3099')new instance is not created and ClientSocket.on_open is called (iodine-0.7.7).
Is it possible to disable the automatic addition of last-modified on certain routes? we are using etags on certain controllers so we do not want to have the last-modified checked. is this possible?
The YARD documentation in the C files is missing some YARD documentation tags, such as @param, @return...
...I would love help with this.
It's easy to take a source file at a time or maybe even fix the documentation for a single function or two at a time.
Great start for newcomers who want to help in on an open source project.
Hi again, I have this in my app to restart the server:
Iodine.run_every(12 * 60 * 60 * 1000) do # each 12 hours
Process.kill('SIGUSR1', Process.pid) unless Iodine.worker?
endAnd this is my config (in config/environments/production.rb)
if defined?(Iodine)
# IODINE
pid_file = '/tmp/rails.pid'
socket_file = 'tmp/sockets/server.sock'
FileUtils.mkdir_p(Rails.root.join('tmp/sockets/'))
Iodine::DEFAULT_SETTINGS[:port] = 0
Iodine::DEFAULT_SETTINGS[:address] = socket_file
Iodine.on_state(:pre_start) do
IO.binwrite(pid_file, Process.pid)
end
endThe problem is that when the server is restarted with USR1 sign the socket(:address) is not created again.

Let me know if you need more information or if i can do any workaround.
The system is running in docker ruby:2.6.2-alpine3.9
Thanks in advance 👍
How can the wss be used with SignalR?
I'm trying to connect to https://github.com/Bittrex/bittrex.github.io but I just can't get it to work.
Hey GitHub Friends,
First at all, I really appreciate about your contributions on GitHub about networks.
I want to ask you a question which stacked me for a while about how to connect signalr client with ruby.
require 'iodine'
class EchoClient
def on_open(connection)
@messages = [ "Hello World!",
"I'm alive and sending messages",
"I also receive messages",
"now that we all know this...",
"I can stop.",
"Goodbye." ]
send_one_message(connection)
end
def boxConnStateChanged(connection, message)
puts "Received: #{message}"
send_one_message(connection)
end
def box_conn_ctate_changed(connection, message)
puts "Received: #{message}"
send_one_message(connection)
end
end
url = "http://fbcs101.fbox360.com/push?at=#{@access_token}&cid=#{@xFboxClientId}"
Iodine.threads = 1
tls = Iodine::TLS.new
Iodine.connect url: url, handler: EchoClient.new, ping: 40, service: :tls, tls: tls
Iodine.start
here are some errors i got
FATAL: No supported SSL/TLS library available.

Hey there!
So far, Iodine has been amazing. There one issue we have is that all of our assets are fingerprinted, so we would effectively like the browser to cache the forever. Currently, the cache-control header is set to max-age=3600, is there a way to adjust the cache-control header for static assets?
When using websockets, multiple calls to each, while under stress (opening and closing multiple websocket connections (tested with over 200), cause Iodine to crash for reasons unknown.
The error reported seems to be write related... this is the relevant part of the log:

First off - thanks for this great app server, and your work to push the Rack Upgrade standard forward!
I'm having issues building this gem on FreeBSD. I've seen reports that we need to use a #undef _POSIX_C_SOURCE which I tried to no-avail.
Just out of curiosity, I went back through the released versions and the latest one that I could build was 0.2.17. Some of them failed with the following message, and some of them complained about error: incomplete definition of type 'struct sockaddr_in'.

Hi again, @boazsegev!
Sorry to bother you again, I will stop now!
I'm running Iodine in my spec suite and I would like to disable request logging.
I'm aware I can disable it when running in the command-line:
bundle exec rspec 2> /dev/nullHowever in my spec suite I'm running it with Capybara, hence I start it from the ruby interface:
# spec/support/capybara_iodine.rb
require 'rack/handler/iodine'
Capybara.register_server :iodine do |app, port, host|
Iodine.workers = 1
Iodine.threads = 1
Iodine::Rack.run(app, Port: port, Address: host)
end
Capybara.server = :iodine
RSpec.configure do |config|
config.after(:suite) do
Iodine.stop
end
endWhen I run bundle exec rspec (without 2> /dev/null) it outputs the following:
$ bundle exec rspec
Running via Spring preloader in process 1254
Randomized with seed 29602
INFO: Listening on port 34365

.Content type: application/x-www-form-urlencoded; charset=UTF-8
..Content type: application/x-www-form-urlencoded; charset=UTF-8
...I know I can run bundle exec rspec 2> /dev/null to suppress the request logs, but I saw that there is an option to disable logging on listen, but I can't use it. I tried like this:
Capybara.register_server :iodine do |app, port, host|
Iodine.workers = 1
Iodine.threads = 1
Iodine.listen(
service: :http,
handler: app,
port: port,
address: host,
log: false
)
Iodine.start
endI get the impression that the case log: false is not being treated.
Is there a way to disable logging in this case?
Thanks in advance for any hint! 😀👍🏻
Hi,
I found that iodine doesn't handle exceptions raised in on_message and on_data callbacks.
Example app:
class MyChatroom
def on_message(data)
raise "SomeError"
end
end
Iodine::Rack.app = Proc.new do |env|
unless env['upgrade.websocket?']
return [404, { 'Content-Type' => 'text/plain' }, ['Not Found']]
end
env['upgrade.websocket'] = MyChatroom.new
[-1, {}, []]
end
Iodine.startWhen an exception raised the whole thread gets stuck and no messages are written to the log.
The messages are shown when the server stops, or when all available threads terminate (and the server crashes).
I guess it's because there is direct Ruby C API function call instead of RubyCaller call
https://github.com/boazsegev/iodine/blob/master/ext/iodine/iodine_websockets.c#L683
there should probably be something like this:
RubyCaller.call_arg(handler, iodine_on_message_func_id, 1, &buffer);Hello,
I've noticed that rake-compiler is being a runtime dependency of this project (iodine), however, I'm not clear how that is used at runtime.
rake-compiler provides a series of tools for gem authors during development and is not aimed to be added as runtime dependency.
You can think of rake-compiler the same way you think of rake and rspec: those are tools that help you build your library, but not necessarily dependencies you want to transfer at runtime to the end user.
Could you confirm the expected need for this dependency?
Thank you. ❤️ ❤️ ❤️
Hi @matthewd , @evanphx , @tinco , @jeremy
This is a quick note to review the state of the specification.
The specification has been out for a while, but it seems to me that it's either underutilized or, more probably, unimplemented.
No changes have been proposed for quite a while, but I think it's because we haven't been testing it rather than because we are pleased with it.
I recently read a very troubling blog post about Websocket performance in Ruby when compared to NodeJS. It seems most Ruby websocket implementations break at ~500 concurrent clients.
The blog [has a repo with the code used].(https://github.com/hashrocket/websocket-shootout).
Iodine now fully supports the specification as far as I can tell (as well as an each extension which isn't part of the specifications) and I tested it with thousands of concurrent clients with positive results.
I would really love to hear how things have been developing on your end and see if there are any changes.
Kind regards,
Bo.
P.S.
I post this here since I'm not sure about the best group communication channel. If you want to guide me on this, or change the communication channel, please let me know.
Hi again!
We have been struggling with a very weird issue recently (that's also something that triggered us to update iodine).
In our websocket use case, we send an initial message to the server right after the handshake is finished. The message is relatively small, something like {"init": true} (we ask server for some initial data).
Every now and then we don't get anything back as if the message didn't make it at all. It happens more often if we are in the same location as the server (i.e. it's a local machine connection, or local network connection).
In our logs we also don't see anything happening with the on_message callback. If we repeat the message second later we get the reply back normally.
Our educated guess (I don't know C well enough) was that the callbacks for messages are set after the websocket handshake is finished - and hence if we are very quick we can squeeze the initial message on the socket before there is anything listening for it.
Could you please take a look if that's the case? Or maybe there is some other race condition in there?
Hi.
My C is a little rusty and I couldn't find much info on it, so I am asking.
How does iodine (or facil.io) handle memory bloat/fragmentation/pollution and restarting processes? I am running a proxy middleware written in Celluloid/Reel that fights with memory fragmentation a lot, despite doing most of the proxying in a C extension that I added. For Puma there is a worker killer that drains the connections and restarts when memory is too high (according to configuration), for Reel I implemented it myself. While I like Celluloid, it's very complex and I was considering to migrate to concurrent-ruby instead, but I don't have many web server options as it seems.
Are there any tools available in iodine that allow you to drain connections and restart the worker? Maybe even automatically? How does it handle memory management in general? I mean we are coming from C-land into Ruby-land and the GC in Ruby is still not very optimal, would it be beneficial to return to C-land? How thread safe is iodine-rack, can I run multiple parallel requests in Ruby-land?
Sorry for the amount of questions, but iodine is far too interesting :)
I ran the pubsub engine example in the gem directory. I opened http://localhost:3000 in Safari, opened a console, and connected a websocket, refreshed, connected again with a name, etc, like:
var ws = new WebSocket("ws://localhost:3000")
ws.send("Hello")
// refresh
var ws = new WebSocket("ws://localhost:3000/ohai")
ws.send("Hello")It segfaulted (and I notice the logs look like output is being fragmented):

Hello,
I don't know whether this project support Rails or not, but I guess it does since Rails is a Rack application :-) anyway, I have the following error:
#<Thread:0x00007fd6d6758cd0@/home/user/.asdf/installs/ruby/2.5.1/lib/ruby/gems/2.5.0/gems/actioncable-5.2.0/lib/action_cable/connection/stream_event_loop.rb:75 run> terminated with exception (report_on_exception is true):

It happens on a newly created Rails 5.2.0 application, Ruby 2.5.1, iodine 0.6.3, visiting any page which includes an ActionCable socket. It can be reproduced with the following steps:
bundle exec iodine -p 3000 -t 8 -w 1 -www public -vThis is a discussion for the proposed upgrade workflow for Rack.
I will update this first post with the information about the outline for implementation. This first draft is based my experience implementing this feature (and using this feature) with Iodine.
We want to switch to Iodine for a rails app that is behind a reverse proxy. The app is mounted on a subfolder of the domain using nginx so we use the SCRIPT_NAME environment variable to make the url helpers return the correct urls.
When using Iodine to serve the app it seems that the SCRIPT_NAME variable is set to "" instead of using the value supplied from the system. From what I could find it seems to happen here:
iodine/ext/iodine/iodine_http.c
Line 837 in 67b08be
Is there a way to configure iodine to use a different SCRIPT_NAME or make it use the system supplied value?
Hey @boazsegev,
We are getting some errors when attempting to parse Last-Modified headers, and I think the error may be coming from iodine generated timestamps. Ruby's httpdate fails when parsing dates without two digits for the day number. I believe this may actually be a ruby bug (couldn't really tell from the spec) but it would be hugely helpful if iodine could bypass this by ensuring two digits :)
