Puppet users - Mar 2009 - imports from default node called when default node not used?

All,
My understanding was that the default node was only used when a node
did not match any other way.  This appears to be correct for anything
included via "include", however, it appears that anything included via
"import" is pulled in regardless of whether the default node is
matched or not.  An example:

site.pp:

node ''buildtest'' {
#    include wget
}

node default {
    # Include everything for the default node
    import "test/*.pp"
    include active_directory
    include backup
}

Inside the test directory is a single class called module_test which
does nothing but include a test module called my_test_module:

$ cat module_test.pp
include my_test_module

class module_test {
}
$

And my_test_module just insures the presence of a file in /tmp:

$ cat init.pp
# Module to test imports

class my_test_module {
    file {
        "/tmp/should_not_be_here":
        mode => 0644,
        ensure => present
    }
}


With this configuration, when I run puppetd on my box, buildtest, it
matches with its node definition.  I''ve tested this by enabling and
disabling the "include wget" line which gets executed appropriately.
Munging the name ''buildtest'' in the node definition causes the
default
node to instantiate, and "include active_directory" and "include
backup" modify their files appropriately.  However, the class
"my_test_module" ALWAYS gets executed and the file "/tmp/
should_no_be_here" is there after every run regardless of their being
a match for ''buildtest'' or not.

Why is this the case?

I experienced something similar when attempting to use "import" inside
a "case" statement. I thought it would be more efficient if the  
puppetmaster didn''t have to evaluate sections that weren''t
going to
get used. (Maybe that''s completely wrong.) Anyway, it seems that all  
"import" lines in your manifests are executed unconditionally.
I''ve
taken to just importing absolutely everything at the beginning and  
then using include to actually load the classes I want. (Most files  
that get imported contain classes now.)

I would also like to hear the official answer on how this is supposed  
to work.

The [documentation][1] says "Code in those external manifests should  
always be stored in a class or definition or it will be imported into  
the main scope and applied to all nodes". When I read that, I think  
"Well, obviously, but only if a particular import statement gets  
triggered", but maybe it''s attempting to warn us that import  
statements are executed unconditionally? If so, the doc needs to be  
clarified, IMO.

Because it screws up the order in which people normally read text.

Imports are parse-time, not compile time.  As Puppet reads the files,  
it evaluates every import immediately.

Please update the documentation to make this clear to your satisfaction.
