Without this patch Puppet Enterprise users who install the most recent
version of stdlib lose the ability to resolve certain facts critical to
the operation of Puppet Enterprise. These facts are defined externally
in the file
`/etc/puppetlabs/facter/facts.d/puppet_enterprise_installer.txt`.
As an example, Puppet Enterprise catalogs fail to compile if the
`fact_stomp_server`, and `fact_stomp_port` facts are not defined.
`facter_dot_d` was removed from stdlib version 4 because Facter version
1.7 now supports external facts defined in
`/etc/puppetlabs/facter/facts.d/puppet_enterprise_installer.txt`.
Puppet Enterprise does not yet include Facter 1.7, however. The most
recent PE release, 2.8.1, includes Facter 1.6.17. With this version of
Facter, users who replace the version of stdlib that ships with PE with
the most recent version from the Forge will lose the ability to resolve
facts from
`/etc/puppetlabs/facter/facts.d/puppet_enterprise_installer.txt`.
This patch addresses the problem by detecting if Facter version < 1.7 is
loaded. If so, then the facter_dot_d.rb facts will be defined using the
stdlib custom fact. If Facter >= 1.7 is being used then stdlib will not
define external facts.
This reverts commit 8fc00ea5b6.
We're restoring facts_dot_d support to stdlib because users are pulling
in the latest version of stdlib while on Puppet Enterprise which breaks
the operation of PE itself when the fact_stomp_server and
fact_stomp_port facts are not defined. They are not defined in PE
because PE runs with Facter 1.6.17 and Puppet 2.7.21
This patch allows an array of resource titles to be passed into
the ensure_resource function. Each item in the array will be
checked for existence and will be created if it doesn't already
exist.
Without this patch the anchor resource does not propogate refresh
events, making it difficult to subscribe to a class which has been
notified by another resource.
This change is to implement a new function "any2array", which will take any
argument or arguments and create an array which contains it. If the argument
is a single array then it will be returned as-is. If the argument is a single
hash then it will be converted into an array. Otherwise (if there are more than
one argument, or the only argument is not an array or a hash) the function will
return an array containing all the arguments.
This is a bit more heavy-handed than I might like, but it does appear to
do the right things:
* accepts numeric input appropriately, truncating floats
* matches string input against a regex, then coerces number-looking
strings to int
* makes a best effort to coerce anything else to a string, then subjects
it to the same treatment
* raises an error in the event of incorrect number of arguments or
non-number-looking strings
I've also included some additional unit tests.
No more coercing to String and regex matching. Instead, we now coerce
to Integer at the beginning or raise an error if we cannot coerce to
Integer.
A consequence of this change is that the function will now accept
blatantly non-numeric strings as input, and return false. This seems a
bit goofy to me, but it's how String#to_i works. If we really don't
like this, then I'm open to suggestions.
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
When prefix and suffix did error checking with positional arguments,
they would not report the position of the argument that failed to
validate. This commit changes the messages to indicate which argument
failed.
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.

As far as i know there's no other puppet-dsl-like way to get parameter of
defined resource, so that's why i implemented getparam function, which takes
resource reference and parameter name and returns parameter value.
Here's another example why this function is really useful:
define config($path, $config_param1, $config_param2) { }
define example_resource($config) {
$path = getparam($config, "path")
notice("Path is $path")
}
define example_resource2($example_resource, $config = getparam($example_resource, "config")) {
$config_param1 = getparam($config, "config_param1")
notice("Config parameter is $config_param1")
}
define example_resource3($example_resource, $config = getparam($example_resource, "config")) {
$config_param2 = getparam($config, "config_param2")
notice("Config parameter is $config_param2")
}
class test_getparam {
config { "config_instance":
path => "/some/config/path",
config_param1 => "someconfigtext1",
config_param2 => "someconfigtext2",
}
example_resource { "example_resource_instance":
config => Config["config_instance"]
}
example_resource2 { "example_resource_instance":
example_resource => Example_resource["example_resource_instance"]
}
example_resource3 { "example_resource_instance":
example_resource => Example_resource2["example_resource_instance"]
}
}
class { "test_getparam": }

Its often the case that modules need to install a handful of packages.
In some cases its worth breaking these dependencies out into their own
modules (e.g., Java). In others it makes more sense to keep them in the
module. This can be problematic when multiple modules depend on common
packages (git, python ruby, etc). ensure_resource was a good first step
towards solving this problem. ensure_resource does not handle arrays and
for 3 or more packages stamping out ensure_resource declarations is
tedious.
ensure_packages is a convenience function that takes an array of packages
and wraps calls to ensure_resource. Currently users cannot specify
package versions. But the function could be extended to use a hash if
that functionality would be useful.
If we manage a file we edit with file_line, it should be autorequired by
file_line. Without this patch applied the relationship is not
automatically setup and the user is forced to manually manage the
relationship.
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.
This reverts commit 8fc00ea5b6.
I really wish we could get this right.
Without this patch there is no branch that contains backwards-comaptible
new functionality relative to the current 3.0.1. There are only
branches that contain backwards-incompatible functionality relative to
3.0.1.
This is a problem because I need to do a release of stdlib that contains
backwards compatible facts but does not contain any breaking changes.
This patch fixes the problem by establishing the 3.1.x branch. This
branch will then revert the backwards incompatible changes from the
3.1.x branch and revert the revets in the 4.x and master branches.
I'll review our merge process, but it seems wrong that there is no place
to separate out incompatible from compatible changes when working beyond
the most recent patch release.
The ensure_resource function actually calls two
other functions, create_resources and defined_with_param.
When calling Puppet functions from Ruby, you sometimes have
to load the functions manually if they have not been called
before.
This commit explicitly loads the functions that ensure_resource
depends on from within the function.
