RVM string cache problem (in rvm_shell)

[jonleighton]

I have RVM installed system-wide, and I am doing something like this in a recipe:

rvm_shell "bundle install" do
  user        'vagrant'
  group       'vagrant'
  ...
end

Due to the setting of the user, canonical_ruby_string in Chef::RVM::StringCache looks for the rvm source file in the "vagrant" user's home directory. However, RVM is installed system-wide, so this causes it to break.

Perhaps it should check the user's home dir, and then fall back to the system wide location.

Oh right, there are two notions of user in this resource:

• A non-nil value denoting a per-user install
• The user to run the script as

And in a lot of cases these two don't overlap.

If you wanted to run bundle install on a system-wide install with the vagrant and another bundle install on a user install for jenkins, which form do you think is clearer:

a)

rvm_shell "bundle install" do
  user "vagrant"
end

rvm_shell "bundle install" do
  rvm_user "jenkins"
end

b)

rvm_shell "bundle install" do
  shell_user "vagrant"
end

rvm_shell "bundle install" do
  user "jenkins"
end

c)
An alternative?

I found a way to keep the user attribute as is, but fall back to system wide if they don't have a user RVM installed (as you suggested). Push coming...

@jonleighton thanks for pointing out this issue. If I didn't quite solve your problem, please reopen.

Thanks, I'll check this stuff out next week when I return to the project I am using chef-rvm on. Cheers!
