[Pkg-puppet-devel] Bug#984603: puppet-master-passenger crashes when ruby-scanf is not installed

[Kienan Stewart]

Package: puppet
Version: 5.5.22-2
Followup-For: Bug #984603
X-Debbugs-Cc: kienan at koumbit.org

Dear Maintainer,

this issue also affects the puppet package. For example, it can be reproduced using the
following command:

$ puppet apply -e '"42".scanf("%i") |$x| { notify {"x": message => $x,} }'
Error: Could not run: cannot load such file -- scanf

Installing ruby-scanf solves the issue.

$ apt install ruby-scanf
...
$ puppet apply -e '"42".scanf("%i") |$x| { notify {"x": message => $x,} }'                                                                                                                    
Notice: Compiled catalog for pc-bullseye.test in environment production in 0.02 seconds                                                                                                                            
Notice: 42
Notice: /Stage[main]/Main/Notify[x]/message: defined 'message' as 42
Notice: Applied catalog in 0.01 seconds

Considering that scanf is a core puppet DSL function, I would like to propose that ruby-scanf
be added as a dependency of the puppet package.

The issue persists in 5.5.22-4 (unstable, at the time of this writing). I expect but have not
confirmed that the version in experimental does not have this issue.

This issue is similar to the upstream issue: https://tickets.puppetlabs.com/browse/PUP-10797

thanks,
kienan
