what if the Autoload you specify names the file itself?

what if it names a file that is already in $LOADED_FEATURES but didn't define Foo?

etc

Mike Pastore

@mwpastore

I thought require kept a hash of loaded files and won’t load a file twice

Brian Shirai

@brixen

exactly

so what happens when you specify a file that has been required for an autoload?

what if that file didn't define Foo

does the autoload fail?

does class Foo just create the class?

@brixen

basically Rubinius just does whatever someone thought to write specs for

Ruby is extremely complex, under-specified, and poorly specified where it is

so, we'll see what MRI says

Mike Pastore

@mwpastore

Sounds good!

hello i'm trying to deploy a rails app with puma using cap, and trying to bind puma to a specific port and have set that in config/deploy/production.rb but the app isn't loading :/

Is there a best practice for embedding a puma server into a multi-threaded ruby app? Namely, not using the puma cli

also, this would be on jruby, so no worries about the GIL getting in the way

Mike Pastore

@mwpastore

@raelik If you install the puma gem under JRuby doesn’t it just run puma using JRuby?

@raelik And if you’re deploying to another application server, do you even need puma?

raelik

@raelik

The app in question is a standalone jruby application, and puma would just be used to provide a json endpoint for monitoring it.

so I don't want to run the app with the puma command, as it already has its own command-line

raelik

@raelik

I've got a way to start it (Events.new, Binder.new & add_tcp_listener, Server.new), just didn't know if there was a more streamlined way

raelik

@raelik

actually, looks like I can call add_tcp_listener directly on the Server, since it'll create it's own Binder instance if necessary

so that'll work

Mike Pastore

@mwpastore

Interesting! I’ve seen other ways to do what you’re doing but that’s pretty cool

raelik

@raelik

    def puma_init
      conf = @config[:puma]
      events = case options[:log].nil?
        when false
          Puma::Events::DEFAULT
        else
          f = File.open(options[:log],'a+')
          e = Puma::Events.new(f, f)
          e.register(:state) {|s| f.close if s == :done }
          e
      end
      server = Puma::Server.new(@monitor,events)
      server.add_tcp_listener(conf[:host] || '127.0.0.1', conf[:port] || '9292')
      server.min_threads = 0
      server.max_threads = conf[:threads] || 1
      server
    end

that's my method for manually initializing puma

raelik

@raelik

@monitor is a rack app initialized elsewhere, @config is a YAML config parsed into a hash, and options comes from methadone.

Anybody working on running Puma on Ruby 2.3 with --enable=frozen-string-literal? I’m trying to fix up enough of the built-in gems in the preview just to get rake test to go :-\

Hey, anyone know what dependencies I need to install puma on apline linux. Thanks. :)

James Moriarty

@jamesmoriarty

apk add --no-cache git imagemagick make gcc libc-dev libxml2-dev libxslt-dev libffi-dev yaml-dev openssl-dev zlib-dev readline-dev

Worked but I think I can eliminate some of those.

hi-o, i'm wondering if anyone has run into issues with puma master reconnecting to active record, using preload_app! and before_fork disconnect!. All of my rails app disconnect, except for redmine, which reconnects after 1 - 2 days.

this is with puma-2.16.0, rails-4.2.5, and pg-0.18.4
