Bernhard,
Unfortunately this is a known issue - list expansion beyond one-level arrays is
iffy when using variable indices - your "foo" example works fine because it has
fixed indices.
The best workaround for this that I can think of is to store the slist elements
as comma-separated strings, and split them using splitstring(), as shown in
this example:
body common control
{
bundlesequence => { "test" };
}
bundle agent test
{
vars:
# Instead of "foo" slist => { "hey", "there" };
"foo" string => "hey,there";
"foo" string => "bar two";
# Instead of "foo" slist => { "good", "bye" };
"foo" string => "good,bye";
"foo" string => "baz two";
methods:
"any" usebundle => foo("test.foo");
}
bundle agent foo(info)
{
vars:
"foos" slist => getindices("$(info)");
reports:
# We print the "two" elements here, and delegate the "one" elements
# to the foo_one bundle through the methods: call
cfengine::
"$(info)[$(foos)]: $($(info)[$(foos)])";
methods:
"any" usebundle => foo_one("$(foos)", "$(info)");
}
bundle agent foo_one(name, info)
{
vars:
"ones" slist => splitstring("$($(info)[$(name)])", ",", "9999");
reports:
cfengine::
"$(info)[$(name)]: $(ones)";
}
