'stdlib::fqdn_rand_string' parameter 'charset' expects a String value, got Undef

[Steven Pritchard]

Describe the Bug

Passing undef as the second argument to fqdn_rand_string results in a compilation error. This worked (unintentionally or not) in previous versions of stdlib.

Expected Behavior

Function returns a random string (as it did in 8.x)

Steps to Reproduce

Steps to reproduce the behavior:

1. Install stdlib 9.0.0

[root@40776c2909e5 /]# puppet module install puppetlabs-stdlib -v 9.0.0
Notice: Preparing to install into /etc/puppetlabs/code/environments/production/modules ...
Notice: Downloading from https://forgeapi.puppet.com ...
Notice: Installing -- do not interrupt ...
/etc/puppetlabs/code/environments/production/modules
└── puppetlabs-stdlib (v9.0.0)

2. Call fqnd_rand_string with undef as the second argument

[root@40776c2909e5 /]# puppet apply -e 'notify { fqdn_rand_string(10, undef, "custom seed"): }'
Warning: This function is deprecated, please use stdlib::fqdn_rand_string instead. at ["unknown", 1]:["unknown", 0]
   (location: /etc/puppetlabs/code/environments/production/modules/stdlib/lib/puppet/functions/deprecation.rb:35:in `deprecation')
Error: Evaluation Error: Error while evaluating a Function Call, 'stdlib::fqdn_rand_string' parameter 'charset' expects a String value, got Undef (line: 1, column: 10) on node 40776c2909e5

Environment

• Version: 9.0.0
• Platform: Rocky Linux 8 (shown here for example, others verified via rspec)

Additional Context

This code worked as recently as stdlib 8.6.0.

Thanks for raising this @silug.
Looks like this is being addressed in #1367, lets see if we can get it moving along.

Sorry @jordanbreen28, I completely missed that PR. It looks like the fix was merged in 24a0f21.

Thanks!
