generate executes inside exec regardless of onlyif or unless exit code

The generate function inside this exec runs without regard for the exit status in onlyif. I have tried the same thing with unless and generate always executes, regardless of exit code.

exec { "execute_command_on_master":
  path => [ "/bin/", "/usr/bin/", ],
  onlyif => "/bin/false",
  command => generate("/tmp/test.sh"),
}

Here is the test script:

cat /tmp/test.sh

#!/bin/bash
/bin/echo `date` >> /tmp/testfile

Is this expected behavior?

Thanks.

The exec will not run, but the generate method is still run to create the output passed into the exec's command parameter

As far as I know, the generate method is always invoked where the catalog is complied, which is on the puppet master in a typical set up, or locally if you are running a puppet apply (either directly, or through a 'masterless' configuration)

Generate Documentation

generate

Calls an external command on the Puppet master and returns the results of the command. Any arguments are passed to the external command as arguments. If the generator does not exit with return code of 0, the generator is considered to have failed and a parse error is thrown. Generators can only have file separators, alphanumerics, dashes, and periods in them. This function will attempt to protect you from malicious generator calls (e.g., those with ‘..’ in them), but it can never be entirely safe. No subshell is used to execute generators, so all shell metacharacters are passed directly to the generator. •Type: rvalue
