Error: Could not prefetch printer provider 'cups': undefined method `include?' for nil:NilClass

[kbotnen]

Hei,

I updated code to newest master, and Now I get the following error:

Error: Could not prefetch printer provider 'cups': undefined method `include?' for nil:NilClass

It worked without this in an earlier version.

Working version: https://gist.github.com/kbotnen/8c52f7b99e759da152a8
Errorenous version: https://gist.github.com/kbotnen/2270d4a8857d657145e6

Despite the error the printers show up on lpstat -v.

If I try to remove a printer I get more errors

==> precise-gui: Error: Could not prefetch printer provider 'cups': undefined method `include?' for nil:NilClass
==> precise-gui: Notice: /Stage[main]/App::Print/Printer[IT_Print_Ricoh]/ensure: removed
==> precise-gui: Debug: Executing '/usr/sbin/lpadmin -x IT_Print_Ricoh'
==> precise-gui: Error: /Stage[main]/App::Print/Printer[IT_Print_Ricoh]: Could not evaluate: Execution of '/usr/sbin/lpadmin -x IT_Print_Ricoh' returned 1: lpadmin: The printer or class does not exist.

It looks like it try to remove the printer even if its not there (which it doesnt know since the prefetch step failed?).

All behaviour observed in a vagrant environment, with a Ubuntu 12.04 box.

Hiya kbotnen,
The provider automatically attempts to remove a failed printer so that you don't end up with a queue in a half working state.

I think the failure is due to the way options handling was changed (I'll check your linked files to double check). iirc I was whitelisting allowed options before, and only scraping the output for those options. I then changed it to allowing any option and now it explodes.

Hi kbotnen, please check with latest HEAD branch.
This specific issue should be fixed.

Hi,

It fixed the original problem on precise, but now I get a error on my trusty-box when i do vagrant up

==> trusty-gui: Notice: /Stage[main]/App::Print/File[/usr/share/ppd/uib]/ensure: created

(the longer debug output is here: https://gist.github.com/kbotnen/eb016d159865acac09e6)

When I do a new vagrant provision it works:

==> trusty-gui: Notice: /Stage[main]/App::Print/Printer[pullprintricoh_ps2]/ensure: created

Hiya kbotnen. Can you verify the status of the cups service after vagrant up? I can't see much wrong with the commands being executed.

I am seeing this issue as well with the following code.

  printer { "UPS_Printer":
    ensure      => present,
    shared      => true,
    uri         => $shipping_printer,
    description => "shipping label printer",
    model       => "raw",
  }

  printer { "PT9800PCN":
    ensure      => present,
    shared      => true,
    uri         => $label_printer,
    description => "Label Printer",
    model       => "raw",
  }

I get the error.

If I comment out one of the resources so I am only declaring one printer at a time the problem goes away.

I checked out master and am on commit

Interesting, I'll add a test similar to your manifest and see if i can replicate it.

The issue has been replicated and I'm working on a fix.

@timdaman This issue is related to trying to fetch PPD options for the 'raw' model which is actually impossible, since theres no PPD.
Updating so that PPD fetching failures are skipped with message.
