Subject: Handles vs Classes - Scope Intersection
Author: nima
Link to topic: https://cfengine.com/forum/read.php?3,18170,18170#msg-18170
Are we free to do the following:
bundle agent Client {
files:
linux::
"$(sys.workdir)/inputs/."
handle => "a_unique_identifier",
comment => "$(this.promiser):$(this.handle)",
copy_from => ...,
classes => DefineSoftClass"$(this.handle)"
;
...:
}
Note that I've defined a single unique identifier, then reused that in the
comment, and also in the dynamic declaration of classes. Basically I'm trying
to minimize the number of unique strings that I need to pull out of thin air to
reduce complexity. I would generally just test this, but since I get so many
cf3 crashes, it's a little difficult to tell what is actually the root cause
for the crash.
In summary, my questions boils down to the following:
1. Is the scope of handle names mutually exclusive to the class names
2. Is the comment field valid
3. Can I define classes based on $(this.handle), as long as I make sure that it
contains only valid characters
Oh one more thing that's bugged me - is this valid:
bundle common control {
vars:
#. Core - Minimal (Don't EVER break these!)...
"bundle" slist => { "Client", "Server" };
"inputs" slist => {
"lib-conf.cf", #. User configurations
"lib-core.cf", #. System variables and library functions
"cf-agent.cf", #. Starting point for cfengine clients & servers
"cf-serverd.cf", #. Cfengine server configuration
};
4. Note the last comma in the slist block. This is so I can move lines around
without having to worry about the absence of the last comma everytime.
