Getting PHP information in a module

I'm trying to copy some files based on two pieces information extracted from the PHP executable:

  • thread safety
  • Extension API version

Initially I used a custom fact:

Facter.add('php_extension_version') do
  setcode do
    Facter::Core::Execution.exec("php -i | awk '/^PHP Extension =>/ { print $4}'") || nil
  end
end

However, this runs before all provisioning is done so the PHP binary is not installed. I resorted to creating, installing and executing a custom shell script which does the provisioning, but that feels completely wrong.

(Also asked this on Stackoverflow at http://stackoverflow.com/questions/32... )

I'm wondering if there is a better way than basically executing 20 lines of shell.

I ended up writing a provider which can query this information using the php binary ; for me it's important to be able to provision a node using a single puppet agent invocation.

You can test for the presence of the PHP binary before computing the value of your custom fact. This will require 2 Puppet agent runs, as you can imagine - the 1st one installs the PHP binary, then the 2nd one computes the custom fact value and possibly provisions more bits based on the value. If that's OK with you, then I think it's the way to go.

Here is an example of using Ruby code to test for the presence of a file before calculating a fact value: https://docs.puppetlabs.com/facter/3.0/custom_facts.html#fact-precedence If the PHP binary is not present, then you can leave the fact value undefined or some other value that represents "binary not present".
