Foreman » Smart Proxy

This is on the latest nightly EL7

I think you have an older version or multiple versions of concurrent-ruby gem installed. Could you try removing them and reinstalling smart-proxy?

I do not, this is fully reproducible on an up-to-date CentOS 7.2 box with a fresh install from foreman nightlies. I tried twice.

[root@centos7-foreman-provision-nightly foreman-proxy]# rpm -qa | grep concurrent
rubygem-concurrent-ruby-1.0.0-2.fm1_11.el7.noarch
sclo-ror42-rubygem-concurrent-ruby-1.0.0-2.el7.noarch

There is something odd going on in bundler, here's the full traceback from proxy.log:

I dug a little in Pry, and I don't know if this is relevant but, if I intercept "/usr/share/gems/gems/bundler_ext-0.4.1/lib/bundler_ext.rb:14:

      require 'pry-remote'; binding.remote_pry if name == 'concurrent-ruby'

And look at the files it's trying to require:

From: /usr/share/gems/gems/bundler_ext-0.4.1/lib/bundler_ext.rb @ line 15 BundlerExt.system_require:

    11: def self.system_require(gemfile, *groups)
    12:   runtime.setup_env
    13: 
    14:   Gemfile.parse(gemfile, *groups).each do |name, gem_dep|
 => 15:     require 'pry-remote'; binding.remote_pry if name == 'concurrent-ruby'
    16:     if System.activate?
    17:       System.activate!(name)
    18:     end
    19: 
    20:     runtime.system_require(gem_dep[:files])
    21:   end
    22: end

[1] pry(BundlerExt)> gem_dep
History not saved; unable to open your history file for writing.
=> {:dep=>
  Gem::Dependency.new("concurrent-ruby",
   Gem::Requirement.new(["~> 1.0"]),
   :runtime),
 :files=>["concurrent-ruby"]}

It's requiring a file called concurrent-ruby, but I think it should just be concurrent? If I modify it:

[2] pry(BundlerExt)> gem_dep[:files] = ['concurrent']
=> ["concurrent"]

The proxy starts fine and puppet API loads.
