Bug #10011

If we use a generic method compatible only with a specific version of Rudder on an agent too old, we have a runtime error on the agent

Description

If I use a technique using package_state on a 3.1 agent, i get the following error on the node:

# /var/rudder/cfengine-community/bin/cf-promises
/var/rudder/cfengine-community/inputs/Test_technique/1.0/Test_technique.cf:15:0: error: Undefined bundle package_state with type usebundle

Node is not working anymore then

We could:
  • create dummy generic method with opposite loading conditions, that would only report error
  • generate them automatically
  • detect that the technique depend on an unavailable generic method, and skip it

or something else more clever

Benoit, what do you think of this ?

We could create dummy generic method with error reports in them (even automatically).
But having opposite condition is difficult because conditions are parsed in shell and it currently doesn't support inverting conditions.

A better solution :
- add a line in list-compatible-input : if a method is not loaded, try to load the .loadfailed file
- generate a new file for each generic method that has conditions named this_generic_method.loadfailed
- this file would contain the same generic method definition with a single error report (use ncf api to parse and know the parameters)

Solution: create a .unsupported.cf for those 4 generic methods.
See dry_run_lib.cf for existing use case.

In 5.1 we added a CFEngine version check when agent starts, tat stops immediately if the agent is too old to avoid this type of behavior.

We could backport it to 5.0.
