Added ruby 2.3 install on centos 7

[Atroskelis]

net-telnet and puma both require Ruby to be over 2.2.

Either you install the old variants of those 2, or update ruby to 2.3

Don't approve this yet, apparently even if 2.3 the apps are installed on 2.3 and there are no paths to the original "ruby"

[wk]

As previously mentioned in #1472 the dependency on Ruby 2.3 is not intentional, and the target version is currently 2.0.

The specific dependencies should be correctly locked in master to enable this. Are you currently working on 0.24.0 or on a recent git master?

[Atroskelis]

My issue is that i keep having to install older dependencies (at least on centos 7 ruby ) every time i install oxidized.

Issues are with net-telnet and puma

gem dependencies shows as follows

Gem oxidized-0.24.0
  asetus (~> 0.1)
  bundler (~> 1.10, development)
  git (~> 1, development)
  minitest (~> 5.8, development)
  mocha (~> 1.1, development)
  net-ssh (~> 4.1.0)
  net-telnet (~> 0)
  pry (~> 0, development)
  rake (~> 10.0, development)
  rubocop (~> 0.57.1, development)
  rugged (>= 0.21.4, ~> 0.21)
  simplecov (>= 0, development)
  slop (~> 3.5)

Gem oxidized-web-0.11.1
  charlock_holmes (~> 0.7.5)
  emk-sinatra-url-for (~> 0.2)
  haml (~> 5.0)
  htmlentities (~> 4.3)
  json (>= 1.7.0)
  oxidized (~> 0.22)
  puma (~> 3)
  rack-test (~> 0.7.0)
  rails_best_practices (~> 1.19, development)
  rake (~> 10.0, development)
  rubocop (~> 0.57.1, development)
  sass (~> 3.3)
  sinatra (>= 1.4.6, ~> 1.4)
  sinatra-contrib (>= 1.4.6, ~> 1.4)

As you can see, there are no limiters on versions for puma and net-telnet, of which latest requires at 2.2 and 2.3

@Atroskelis thanks for the detail; could you specify if you install oxidized using gem from rubyforge, or if you experience this when building the oxidized and oxidized-web gems locally from the current git master?

This is a known issue in the current release (and will normally be resolved once a new release takes place), and is expected. It is not expected in current master.

[wk]

This should be resolved with the release of 0.25.1, could you see if the current gem / git is still having difficulties building under older Ruby versions?

[Atroskelis]

Sorry for the late reply.

I tried installing oxidized on centos 7 a few days ago. The oxidized worked fine, as always, but oxidized-web has another dependency who needs Ruby 2.2

This time its rb-inotify.

[wk]

As of #1718, minimal supported Ruby is 2.3 for both oxidized and oxidized-web. I've updated your proposed documentation changes to reflect that, and will shortly pull them in.

Thanks!
