Puppet users - May 2010 - Augeas in puppet behaves differently than augtool?

Hi all,

I''m trying to do fairly simple stuff with augeas, like:

augeas { "cronapt - mailon":
  context => "/files/etc/cron-apt/config",
  changes => "set MAILON upgrade",
  onlyif  => "match MAILON != [''upgrade'']",
}

This works if I try it from the commandline:

tim@puppet-test.db:~$ sudo augtool
augtool> set /files/etc/cron-apt/config/MAILON update
augtool> save
Saved 1 file(s)
augtool>

However, when I try to do this from puppet, the whole files get
emptied out, only the one expected line get added (MAILON=upgrade) and
puppet reports and error:

Is anyone able to shed some light on the issue? This is puppetmasterd
and puppet 0.25.5rc3, by the way. Using libaugeas-ruby1.8
0.3.0-1~bpo50+1 on Debian Lenny.

What are you trying to do with the onlyif?  If that works in augtool, and
that''s what you want, just remove the onlyif.

Without the onlyif, I''m still getting the error:

I thought I needed the onlyif to prevent it from applying every run.

It will only apply it if the command results in a file(s) being changed.  That
means you often need it for insert statements, but almost never need it for set
statements.

That''s strange.  Can you post a copy of the cron-apt config file? 
I''d like to play around with it and see if I get the same problem.

I can, but it''s so simple, I''m not even going to bother :) The
default
config file is everything commented out. That''s it. So a file full of
lines starting with # :)

I made a lens that just uses the default Shellvars.lns without
modifications except for the path.

Hi all,

To expand on this, I tried it from the irb:

tim@puppet-test.db:~/augeas/lenses$ sudo irb
irb(main):001:0> require ''augeas''
=> true
irb(main):002:0> Augeas::open do |aug|
irb(main):003:1* aug.set("/files/etc/cron-apt/config/
MAILON","upgrade")
irb(main):004:1> unless aug.save
irb(main):005:2>         raise IOError, "Failed to save changes"
irb(main):006:2>       end
irb(main):007:1>     end
=> nil
irb(main):008:0>

But the puppet recipe still goes wrong. Any ideas?

Hi all,

Okay, I found it, but I cannot explain what''s happening here. Hope
someone else can.

I was adding a load_patch with value "/usr/local/share/augeas/lenses".
When I add that, I get the error. If I leave it out, it works.
However, I have no idea how Augeas knows that it should be searching /
usr/local/share/augeas/lenses.

For the record, load_path seemed to work as expected in 0.25.4. Not
sure what changed it.

Hi all,

Finally found my problem. Apparantly, the default shellvars.aug lens
already includes the config to make it apply to /etc/cron-apt/config.
When I added my cronapt.aug custom lens, there was a clash of two
lenses telling augeas they were applicable on the same file.

So, PEBKAC. Apologies for the noise.
