Without this patch, the previous change set to the
validate_absolute_path() parser function contains Puppet 2.6
incompatible changes. stdlib 2.x is compatible with Puppet 2.6. These
changes are a problem because we cannot introduce backwards incompatible
changes in a minor release.
This patch fixes the problem by back porting the implementation of the
`Puppet::Util.absolute_path?` from 2.7.x to the function block itself.
The function block tests to see if `Puppet::Util.absolute_path?` will
respond and if not, falls back to the inline back ported implementation.
The spec tests have been updated to simulate the behavior of Puppet 2.6
even when running with Puppet 2.7.
This patch adds a new function to validate if a string is an absolute
filesystem path or not.
The intent of this is to make this functionality generic and reusable.
Josh left a comment in another pull request I had:
If node_installdir or $node_vardir is not defined, then we should
raise an error, otherwise we may create a scheduled task to an
untrusted directory.
One solution to this comment is to validate the Puppet variable is an
absolute path.
Examples of this function look like:
function_validate_absolute_path
Using Puppet::Parser::Scope.new
