Puppet users - Apr 2008 - Require not honored with generate() function?

Hi there,

I''m having an issue with generate() function and the Require type.
Here is the manifest snippet:

    file { "/etc/apache2/extra":
        mode => 755,
        owner  => "root",
        group  => "root",
        recurse => true,
        source => ''puppet:///conf/apache/extra''
    }

    file { "/etc/apache2/htpasswd-all":
      ensure => present,
      mode   => 644,
      owner  => root,
      group  => root,
      content => generate("/bin/cat",
"/etc/apache2/extra/htpasswd_1",
"/etc/apache2/extra/htpasswd_2",
      # FIXME this require has no effect!
      require => File["/etc/apache2/extra"]
    }

When I run puppetd, I get this error:

err: Could not retrieve catalog: Failed to execute generator /bin/cat:
Execution of ''/bin/cat /etc/apache2/extra/htpasswd_1
/etc/apache2/extra/htpasswd_2'' returned 256: /bin/cat:
/etc/apache2/extra/htpasswd_1: No such file or directory
/bin/cat: /etc/apache2/extra/htpasswd_2: No such file or directory
 at /.../puppet/manifests/apache.pp:72 on node myhost

The File["/etc/apache2/extra"] requirement is not honored.  Seems like
generate() is evaluated first.

Any idea what is wrong here?

Cheers,

Once again, you''re confusing what happens on the server vs. the client.

*All* functions evaluate on the server. That exception you''re seeing  
is generated on the server.

Relationships only matter on the client.

OK I''ll try to write a custom type then.  Thanks for your answers.

If that kind of things is written in the "pulling strings" book,
I''ll
definitely have to buy a copy :-)

I don''t know that it is; it''s just something you have to
understand
about how responsibilities are split.

Watching your server logs in addition to your client logs (especially  
when testing new code), or at least recognizing when an error is  
likely to have been generated on the server, is a good place to start.

It is indeed written there along with many other useful pieces of
information. :)

Question about your generate example in the book, it looks to me to me
like that example is showing a "client" use of generate. From waht
Luke said that should not work. It would in practice give you a list
of the server eth0 setting instead of hte client.

Its not a client use - that call would generate and return the results
of ifconfig eth0 on the server - as the start of the section states:

"Functions only run on the Puppet master. They are executed when the
configuration on the master is parsed and compiled. So when you execute
functions, you only have access to the resources on the master plus any
Facter facts gathered from your nodes."
