What is it?

A Puppet module that can construct files from fragments.

Please see the comments in the various .pp files for details as well as posts on my blog at http://www.devco.net/

Released under the Apache 2.0 licence

Usage:

If you wanted a /etc/motd file that listed all the major modules on the machine. And that would be maintained automatically even if you just remove the include lines for other modules you could use code like below, a sample /etc/motd would be:

Local sysadmins can also append to the file by just editing /etc/motd.local their changes will be incorporated into the puppet managed motd.

Detailed documentation of the class options can be found in the manifest files.

Known Issues:

• Since puppet-concat now relies on a fact for the concat directory, you will need to set up pluginsync = true on the [master] section of your node's '/etc/puppet/puppet.conf' for at least the first run. You have this issue if puppet fails to run on the client and you have a message similar to "err: Failed to apply catalog: Parameter path failed: File paths must be fully qualified, not 'undef' at [...]/concat/manifests/setup.pp:44".

• Provided 0.24.8 support, shell warnings and empty file creation support.

• Various patches to improve safety of file operations
• Symlink support

David Schmitt

• Patch to remove hard coded paths relying on OS path
• Patch to use file{} to copy the resulting file to the final destination. This means Puppet client will show diffs and that hopefully we can change file ownerships now

Summary:

Many new features and bugfixes in this release, and if you're a heavy concat user you should test carefully before upgrading. The features should all be backwards compatible but only light testing has been done from our side before this release.

Features:

• New parameters in concat:
• replace: specify if concat should replace existing files.
• ensure_newline: controls if fragments should contain a newline at the end.
• Improved README documentation.
• Add rspec:system tests (rake spec:system to test concat)

Bugfixes

• Gracefully handle \n in a fragment resource name.
• Adding more helpful message for 'pluginsync = true'
• Allow passing source and content directly to file resource, rather than defining resource defaults.
• Added -r flag to read so that filenames with \ will be read correctly.
• sort always uses LANG=C.
• Allow WARNMSG to contain/start with '#'.
• Replace while-read pattern with for-do in order to support Solaris.

CHANGELOG:

• 2010/02/19 - initial release
• 2010/03/12 - add support for 0.24.8 and newer

         - make the location of sort configurable
         - add the ability to add shell comment based warnings to
           top of files
         - add the ablity to create empty files
  

• 2010/04/05 - fix parsing of WARN and change code style to match rest of the code

         - Better and safer boolean handling for warn and force
         - Don't use hard coded paths in the shell script, set PATH
           top of the script
         - Use file{} to copy the result and make all fragments owned
           by root.  This means we can chnage the ownership/group of the
           resulting file at any time.
         - You can specify ensure => "/some/other/file" in concat::fragment
           to include the contents of a symlink into the final file.
