From 012cd99bb6f1fdf210a2bc1c3f153138643dfb48 Mon Sep 17 00:00:00 2001 From: Trevor Vaughan Date: Wed, 31 May 2017 11:33:11 -0400 Subject: [PATCH] Provide the option to only update the live value (#15) There are some sysctl values which, when set in /etc/sysctl.conf, may cause operational harm to a system. This patch provides the ability to only update the live value and make the disk persistence optional. Additionally: - Now use prefetching to get the sysctl values - Updated self.instances to obtain information about all sysctl values which provides a more accurate representation of the system when using `puppet resource` - Fail if the user attempts to set a value that is not valid on the system unless `silent` is set. - Updated all tests - Refactored Travis CI Tests - Added OpenSUSE support Closes #14 --- .gitignore | 2 + .travis.yml | 62 +------- CHANGELOG.md | 13 ++ Gemfile | 2 + README.md | 8 + lib/puppet/provider/sysctl/augeas.rb | 147 ++++++++++++++---- lib/puppet/type/sysctl.rb | 35 ++++- metadata.json | 8 +- spec/acceptance/nodesets/default.yml | 36 +++-- spec/acceptance/sysctl_spec.rb | 88 ++++++++++- .../puppet/provider/sysctl/augeas_spec.rb | 74 ++++++--- spec/unit/puppet/type/sysctl_spec.rb | 17 ++ 12 files changed, 369 insertions(+), 123 deletions(-) diff --git a/.gitignore b/.gitignore index 94145ab..7682b0a 100644 --- a/.gitignore +++ b/.gitignore @@ -1,3 +1,4 @@ +Gemfile.lock pkg coverage .bundle/ @@ -9,6 +10,7 @@ spec/fixtures/manifests spec/fixtures/modules yardoc/ .yardoc/ +log/ ## Ruby .rvmrc* diff --git a/.travis.yml b/.travis.yml index 2eaaa56..ff53ea0 100644 --- a/.travis.yml +++ b/.travis.yml @@ -1,66 +1,20 @@ language: ruby sudo: required rvm: -
