testing augeas resources gives a permission denied error on linux and osx

[sirinek]

On both OSX 10.12.6 and RHEL 7.3, testing my augeas resource throws an error trying to create temporary directories. The below was from using PDK on my OSX 10.12.6 system. I get the same issue when doing this on a RHEL7 host.

I am using PDK 1.3, and extra gems being used are rspec-puppet-augeas-0.4.0 and ruby-augeas-0.5.0.

  etc_system::solaris_kernel_parameter Augeas[ip_squeue_enter] should change ip_squeue_enter
  Failure/Error:

    describe_augeas 'ip_squeue_enter', :target => 'dest/etc/system', :fixture => 'src/etc/system', :lens => 'Solaris_System' do
      it 'should change ip_squeue_enter' do
        is_expected.to execute.with_change
        aug_get('set[./variable="ip_squeue_enter"]/value').should == '4'

Here's the code for ./spec/defines/etc_system_solaris_kernel_parameter_spec.rb:

require 'spec_helper'

describe 'etc_system::solaris_kernel_parameter' do
  let(:title) { 'ip_squeue_enter' }
  let(:params) {
    {
      :value => '4',
      :module => 'ip'
    }
  }
  it 'has an augeas resource' do
      is_expected.to compile
      is_expected.to contain_augeas('ip_squeue_enter')
      is_expected.to contain_etc_system__solaris_kernel_parameter('ip_squeue_enter').with('variable' => 'ip_squeue_enter', 'value' => '4', 'operator' => '=', 'module' => 'ip')
  end

  describe_augeas 'ip_squeue_enter', :target => 'dest/etc/system', :fixture => 'src/etc/system', :lens => 'Solaris_System' do
    it 'should change ip_squeue_enter' do
      is_expected.to execute.with_change
      aug_get('set[./variable="ip_squeue_enter"]/value').should == '4'
      is_expected.to execute.idempotently
    end
  end
end

The failure goes away when commenting out the it 'should change ip_squeue_enter' block.

In case it is necessary here is the code for the defined type I have in puppet:

define etc_system::solaris_kernel_parameter(
  $variable = $title,
  $module = false,
  $operator = '=',
  $value = 0
) {

  if $module {
    augeas { $variable:
      incl    => '/etc/system',
      lens    => 'Solaris_System.lns',
      changes => [
        "rm set[./variable='${variable}']",
        "set set[./variable='${variable}']/variable \'${variable}\'",
        "ins module before set[./variable='${variable}']/variable",
        "set set[./variable='${variable}']/module \'${module}\'",
        "set set[./variable='${variable}']/operator \'${operator}\'",
        "set set[./variable='${variable}']/value \'${value}\'"
      ],
      onlyif  => "get set[./variable='${variable}']/value != \"${value}\"",
    }
  }
  else {
    augeas { $variable:
      incl    => '/etc/system',
      lens    => 'Solaris_System.lns',
      changes => [
        "rm set[./variable='${variable}']",
        "set set[./variable='${variable}']/variable \'${variable}\'",
        "set set[./variable='${variable}']/operator \'${operator}\'",
        "set set[./variable='${variable}']/value \'${value}\'"
      ],
      onlyif  => "get set[./variable='${variable}']/value != \"${value}\"",
    }
  }

}

Someone responded with some good information at https://groups.google.com/forum/#!topic/puppet-users/BVeNnpnh8OM

Among other things the response says "the issue is with rspec-puppet-augeas trying to set up a fixture. Note that uid 119 is "puppet" on my system. So somewhere in there the rspec-puppet-augeas gem and puppet get confused about the context they're running in. I can't help you with that."

Hi! Were you able to resolve this, @sirinek ? I've just started defining the specs my Augeas-using modules and am hitting this issue :(

[nward]

OK, this looks like it's come up a bunch before - root cause is because this tries to execute a puppet manifest, puppet will try make sure all the dirs it needs are in place (ssl, etc.).

This looks like a duplicate of: https://github.com/domcleal/rspec-puppet-augeas/issues/14 https://github.com/domcleal/rspec-puppet-augeas/issues/15

This should have been fixed by https://github.com/domcleal/rspec-puppet-augeas/commit/30fc5f0b7db49645e1000afa3477f84edb621efd

I see a suggestion around for running fakeroot, but that doesn't seem to work for me (OS X).. will keep poking at this one..

Hey @nward, just now seeing this, sorry. I have not been able to work around the issue. I am doing my tests on RHEL7 like most of my puppet agents now instead of using my macbook, we don't run puppet on any Mac hosts, and when I move these tests to our CI setup they will be on RHEL anyway.
