Structured custom fact behavior

[Guto Carvalho]

Hi guys,

I'm playing around with custom facts, I'm trying to create a simple custom (structured) fact. 

[root@centos7 ~]# puppet --version

4.2.1

[root@centos7 ~]# facter --version

3.0.2 (commit 5dc120fa9db4c19150466b1bbd1d0cf42c87c6bd)

Here is my code

https://gist.github.com/gutocarvalho/d60987f4cee423d017c4

The fact is almost working

root@centos7 ~]# facter -p postgresql

{

  installed => true,

  version => "9.2.13"

}

When I try to print the fact value using notify it works fine

notify { "PostgreSQL version is ${::postgresql['version']}":

info: Applying configuration version '1447812110'

Notice: PostgreSQL version is 9.2.13

Notice: /Stage[main]/Main/Node[centos7.puppet]/Notify[PostgreSQL version is 9.2.13]/message: defined 'message' as 'PostgreSQL version is 9.2.13'

But, when I try to call postgresql.installed or postgresql.version facter doesn't show any result.

[root@centos7 ~]# facter -p postgresql.installed

[root@centos7 ~]# facter -p postgresql.version

What could possibly cause this?

This was a bug in facter that was recently fixed. The bug was that facts from ruby (i.e. custom facts) were not able to be traversed by facter's command line query.  I'm on a mobile device at the moment, so I'll follow-up with a link to a ticket when I can.

FYI, this was FACT-1254: https://tickets.puppetlabs.com/browse/FACT-1254

It was fixed in Facter 3.1.2.
