Feature/respect ruby version file

[gucki]

1. Running cap staging rvm:check now always outputs something, not only when log_level is set to debug. It's now only automatically invoked on normal deploying if the log_level is debug, so no change in behavior here.
2. cap staging rvm:check is now executed in the current release path, so RVM will pickup any .ruby-version file and only fall back to the system defaults.
3. rvm_ruby_version is no longer set to default. Instead the ruby version reported by cap staging rvm:check is used by default now.

Anybody has an idea on how to improve on this here? Thanks 👍

I made some changes in the meanwhile:

1. The ruby version is now redetected after the repository has been checked out. This is important when new version of the application has a different ruby version than the current release.
2. The code now requires an sshkit version which has my command prefix proc support build in. See Added support for procs to command prefixes sshkit#194

Looks nice, but I'd avoid calling Rake::Task from Capistrano extension since it may conflict with Rake.

What is left here?

👍 would be great to have this merged in. At the present, it is very cumbersome to upgrade ruby versions.

Any updates on this?

FWIW, today capistrano/rvm still prefixes with rvm default do by default, which can be problematic (e.g. if you use both JRuby & MRI on a server setup, if you plan major Ruby + code upgrades etc).

As I mentioned in #59, I found that just using this works nicely:

set :rvm_ruby_version, IO.read('.ruby-version')

[dmitry]

set :rvm_ruby_version, IO.read('.ruby-version').strip

I have new line on the end of the string, which is prevents from deployment.

For Googlers:

You might see some vague error like this if you did not apply the .strip as mentioned by @dmitry

bundle stderr: bash: -c: line 1: syntax error near unexpected token `do' bash: -c: line 1: ` do bundle config --local deployment true )'
