An optional third parameter can be given a min length. The function
then only passes successfully, if all strings are in the range
min_length <= string <= max_length
update and fix function and unit tests
the check for the minlength has to be written differently
because 0 values should be possible. We now check
a) if the input is convertible, and throw a ParseError and
b) if the input .is_a?(Numeric) and ask for a positive number
it's not as clean as for maxlength, but keeps a similar behaviour
refined the error checking for the min length
try to convert to Integer(args[2]) and fail,
if it's not possible
changed the tests accordingly to the new parameter checking
This patch is the same approach as the one that want into 2.2.x. It
covers the functions in 2.3.x that do not exist in 2.2.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.
This function is used to validate a string is less than a maximum length. The
string, or array of strings, is passed as the first argument to the function.
The maximum length of the string is passed as the second argument.
It is useful to validate, for example, that Puppet is not sending a username
to a downstream system that the system cannot cope with, but that might not
cause an error message - for example, MySQL will not accept a username of
more than 16 characters. This enables a Puppet administrator to validate
the data that it may have been passed from upstream through, for example,
Hiera.
