I tested your code and indeed, it is a strange behavior.
I guess the root cause of the problem is the `refreshonly => true` of exec-CCC.
My reading of the situation:
- exec-BBB runs and fails, sending nothing to exec-CCC.
- exec-CCC has `refreshonly => true`, since exec-BBB has failed, it
does nothing.
- exec-DDD runs, even having `require => Exec['exec-CCC']` which has
not received a notify because exec-BBB failed.
I did a test using the chaining syntax and the behavior is the same:
Exec['exec-AAA'] ~> Exec['exec-BBB'] ~> Exec['exec-CCC'] -> Exec['exec-DDD']
# puppet apply test.pp
/Stage[main]//Exec[exec-AAA]/returns: executed successfully
Error: /Stage[main]//Exec[exec-BBB]: Failed to call refresh:
/bin/false returned 1 instead of one of [0]
Error: /Stage[main]//Exec[exec-BBB]: /bin/false returned 1 instead of one of [0]
/Stage[main]//Exec[exec-DDD]/returns: executed successfully
Exec['exec-CCC'] does not receive a notification and does not run
because exec-BBB failed. Although, it fulfills the `require`
relationship with Exec['exec-DDD'], which runs.
Note: changing the relationship of Exec['exec-CCC'] and
Exec['exec-DDD'] from `require` para `notify` does not solve the
problem, the behavior is the same.
Very odd. The documentation about `exec` does not say anything about
this behavior of `refreshonly` [1].
