external facts script not working, but only when puppet agent is run as a daemon

[Ugo Bellavance]

Hi,

I'm a beginner with PHP but I managed to get two scripts to work for generating external facts for a puppet module.  These scripts work perfectly when I run puppet manually (puppet agent --test), but when the puppet agent is started as a daemon (systmctl start puppet), facts are not generated. Both scripts give the same error:

start-puppet-agent: Fact file /var/lib/puppet/facts.d/get_extensions_details.php was parsed but returned an empty data set

start-puppet-agent: Fact file /var/lib/puppet/facts.d/get_directives_details.php was parsed but returned an empty data set

I wonder what kind of difference could cause that.

I tried debugging as much as I can, but it looks like the array $arr is not fed by the json_decode function. I think json support is built-in so the php config should not matter. PHP throws this error: invalid argument supplied for foreach()

Scripts:

https://github.com/zend-patterns/ZendServerPuppet/blob/master/facts.d/get_extensions_details.php

(still) running puppet 3

Thanks,

I found it: the PHP script threw PHP Notices when run as a daemon because of uninitialized variables.  Got rid of them and now the script works when puppet agent is run as a daemon.

What I meant exactly is that the error messages were added to the json, so when I tried to load the json into an array, I got an error saying that the input was not a standard json string.
