Please pay special attention to the upgrade instructions below.<\/p>\n<h1>Changes in this release<\/h1>\n<ul>\n<li>Several robustness improvements to the helper shell script.<\/li>\n<li>Removed all hard coded paths in the helper script to improve portability.<\/li>\n<li>We now use file{} to copy the combined file to its location.  This means you can now change the ownership of a file by just changing the owner\/group in <i>concat{}<\/i>.<\/li>\n<li>You can specify <i>ensure => &#8220;\/some\/other\/file&#8221;<\/i> in <i>concat::fragment<\/i> to include the contents of another file in the fragment.  Even files not managed by puppet.<\/li>\n<li>The code is now <a href=\"http:\/\/github.com\/ripienaar\/puppet-concat\">hosted on Github<\/a> and we&#8217;ll accept patches there.<\/li>\n<\/ul>\n<h1>Upgrading<\/h1>\n<p>When upgrading to this version you need to take particular care.  All the fragments are now owned by root, the shell script runs as root and we use file{} to copy the resulting file out.<\/p>\n<p>This means you&#8217;ll see the diff of not just the fragments but also the final file when running <i>puppetd &#8211;test<\/i> but unfortunately it also means the first time you run puppet with the new code your Puppet will fire off all notifies that you have on your concat{} resources.  You&#8217;ll also see a lot of changes to resources in the fragments directory on first run.  This is normal and expected behavior.<\/p>\n<p>So if say you&#8217;re using the concat to create <i>my.cf<\/i> and notify the service to restart automatically then simply upgrading this module will result in MySQL restarting.  This is a one off notify that happens only the first time, from then on it will be as normal.   So I&#8217;d suggest when upgrading to disable those notifies till this upgrade is running everywhere and then put it back.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I&#8217;ve had quite a lot of contributions to my Puppet Concat module and after some testing by various people I&#8217;m ready to do a new release.
