Hi all,
I kinda got lost in Henrik's RFC wrt Puppet resource defaults. Perhaps
this was already discussed there but I couldn't find it quickly.
What I would like to propose is that the realisation side-effect of
collectors be removed and instead have an explicit way to realise resources.
The problem is most obvious when you look at configuring a package
manager and making sure that it is _before_ Package resources can be
processed.
The canonical way of doing this, and the way we recommend for users of
puppetlabs-apt, is this little snippet:
Class['apt::update'] -> Package <||>
Every apt::source notifies a refresh_only exec inside the apt::update
class so this finalises the circle.
The reason the module doesn't do this by default is because of the side
effect on <||>. If people were using virtual package resources, for
whatever reason, our module would now realise them for them and they
lose the little bit of control they had over that part.
The other way to solve this that I'm aware of would be stages, but you
know, stages.
Essentially what I want to be able to do is declare the intent of a
relation between any two resources or 'bags' of resource types in the
catalog and have that relation taken into account when the resource is
realised, without causing realisation at that point.
Completely agree - the language needs a way to query that is separate
from realizing and overriding at the same time.
We should get to that after 4.0.
