Puppet applies new file, then reverts it back

[Nicholas Miller]

Hi All,

I'm having a strange issue with one particular file where puppet applies the new file, then reverts back.  It does this every time puppet runs, see below:

C:\Program Files (x86)\Puppet Labs\Puppet\bin>puppet agent -t

Has anyone ever had this problem before?  Any ideas on how to fix it?

Thanks,

That is very strange.  Puppet should never manage the same resource twice in the same catalog run, and in any given run, Puppet should never modify the same property of the same resource more than once.  These are such fundamental Puppet principles that I'm inclined to guess that rather than Puppet doing either of the above, it is instead managing two distinct (from its perspective) resources that somehow resolve to the same physical resource.

I have not had that problem, but if I have guessed right about its nature then you should look carefully at your manifests to find the resource duplication (which will revolve around something about the file name and / or path of two File resources that the catalog compiler doesn't recognize as being equivalent).  You could also look at the cached catalog to verify that there are indeed two file resources corresponding to the given file; if so, then it is conceivable that comparing them will reveal the nature of the collision.

In any event, it may be that running the agent with --debug output enabled will provide useful additional information.

I've seen this sort of problem on Windows when mixing upper and lower case file paths, so given

  file { 'C:/foo':

    ensure => file,

    content => 'upper',

  }

  file { 'c:/foo':

    ensure => file,

    content => 'lower',

  }

Puppet will try to apply both resources, not realizing they are in fact the same resource on a Windows case-insensitive filesystem:

C:\work\puppet> bundle exec puppet apply file.pp

...

Notice: /Stage[main]/Main/File[C:/foo]/content: content changed '{md5}81e073b428b50247daba38531dcf412a' to '{md5}0122b4c2c01ee1c698ecc309d2b8eb5a'

Notice: /Stage[main]/Main/File[c:/foo]/content: content changed '{md5}0122b4c2c01ee1c698ecc309d2b8eb5a' to '{md5}81e073b428b50247daba38531dcf412a'

But the output from your agent run seems to use the same case...

Josh is correct. The first resource has a character with a different case. Notice the p in the filename. You are managing two different resources from puppet's perspective.

C:/LiveServices/LiveObjectWebServer/Plugins/LiveBuilder/LiveBuilderplugin.lsp

Versus

C:/LiveServices/LiveObjectWebServer/Plugins/LiveBuilder/LiveBuilderPlugin.lsp
