Puppet passes numbers as String to functions, but it makes more sense to
compare them as Numeric.
But sometimes Puppet passes them as the wrong type, see:
https://projects.puppetlabs.com/issues/19812
This function provides a simple wrapper around
Puppet::Parser::Functions.function for access within Puppet manifests.
This will allow users to check whether or not a plugin or functionality
such as hiera is installed on the server.
This reverts commit f7a18189ec, reversing
changes made to 36a7b29630.
I'm reverting this change because of concerns raised by Peter Meier that
it duplicates the "in" operator in the DSL. The "in" operator is new
information that I did not posses when I made the decision to merge.
Because of this new information I'm un-merging and continuing the
discussion in the comments of
https://projects.puppetlabs.com/issues/19272
Reference: GH-130
It is exceptionally difficult to determine if an array contains an element matching a specific value without an iteration or loop construct.
This function is the Puppet equivalent of Array.includes?(foo) in Ruby. The implementation is a verbatim copy of has_key() with the minor modifications needed to support arrays instead of hashes.
Without this patch applied there is no easy way to append one array to
another. This is a problem because it is often desirable to join two
arrays without flattening the contents into a single, one dimensional
array.
This patch addresses the problem by adding a `concat()` function which
takes two arguments. The arguments will be concatenated together and a
new array returned to the caller.

Add test/validation for is_float if created from an arithmetical operation
Add test/validation for is_integer if created from an arithmetical operation
Add test/validation for is_numeric if created from an arithmetical operation
This commit adds a function that joins each of a hash's keys with that
key's corresponding value, separated by a separator string. The
arguments are a hash and separator string. The return value is an
array of joined key/value pairs.
Previous to this commit, the delete function only acted on
arrays. This commit adds the same functionality for hashes and strings
in the obvious way: delete(h, k) would delete the k key from the h
hash and delete(s, sub) would delete all instances of the sub
substring from the s string.
This function is similar to a coalesce function in SQL in that it will
return
the first value in a list of values that is not undefined or an empty
string
(two things in Puppet that will return a boolean false value).
Typically,
this function is used to check for a value in the Puppet
Dashboard/Enterprise
Console, and failover to a default value like the following:
$real_jenkins_version = pick($::jenkins_version, '1.449')
The value of $real_jenkins_version will first look for a top-scope
variable
called 'jenkins_version' (note that parameters set in the Puppet
Dashboard/
Enterprise Console are brought into Puppet as top-scope variables), and,
failing that, will use a default value of 1.449.
If one wishes to test if a host has a particular IP address (such as a floating
virtual address) or has an interface on a particular network (such as a
secondary management network), the facts that provide this information are
difficult to use within Puppet.
This patch addresses these needs by implementing functions
‘has_ip_address(value)’ and ‘has_ip_network(value)’. These functions look
through all interfaces for ipaddress_<interface> and network_<interface>
(respectively) having the requested <value>.
These functions are implemented on top of a lower-level predicate
function, ‘has_interface_with(kind, value)’, which iterates through the
interfaces in the ‘interfaces’ fact and checks the facts <kind>_<interface>
looking for <value>.
Additionally, the existence of a particular named interface can be checked for
by calling with only a single argument: has_interface_with(interface).
A Boolean is returned in all cases.
Without this patch applied the spec tests are invalid because they call
rvalue functions as if they were statements. This is a problem because
Puppet 2.7.x currently throws an exception if a rvalue function is
invoked as if it were a statement function. This exception from Puppet
is causing tests to fail.
This patch fixes the problem by changing the tests to assign the return
value of the functions to a variable. This fixes the problem by
invoking the functions properly.

This patch is the same approach as the one that want into 2.3.x. It
covers the functions in master that do not exist in 2.3.x.
Without this patch all of the spec tests for parser functions in stdlib
would instantiate their own scope instances. This is a problem because
the standard library is tightly coupled with the internal behavior of
Puppet. Tight coupling like this creates failures when we change the
internal behavior of Puppet. This is exactly what happened recently
when we changed the method signature for the initializer of
Puppet::Parser::Scope instances.
This patch fixes the problem by creating scope instances using the
puppet labs spec helper. The specific method that provides scope
instances in Puppet-version-independent way is something like this:
let(:scope) { PuppetlabsSpec::PuppetInternals.scope }
This patch simply implements this across the board.

In Puppet 2.6.x there is a bug where a function may be incorrectly detected as
an rvalue when it is not, or not detected when it is. This means that in tests
the correct syntax for calling a function will be rejected. This disables
those tests on 2.6.x, as there is no straightforward way to write them to be
compatible with both 2.6.x and newer versions of Puppet.

The test_helper code in Puppet now resets function state between each test.
This patch fixes two spec files where the function was not actually loaded in
the tests, causing them to fail.
A bug fix in Puppet exposed that several tests were using rvalue functions
incorrectly (this was not properly checked by puppet before). This fixes those
tests.
