Martin Atkins 289bb60ce1 core: Defer on transitive dependencies for data resources with conditions When a data resource is used for the purposes of verifying a condition about an object managed elsewhere (e.g. if the managed resource doesn't directly export all of the information required for the condition) it's important that we defer the data resource read to the apply step if the corresponding managed resource has any changes pending. Typically we'd expect that to come "for free" but unfortunately we have a pragmatic special case in our handling of data resources where we normally defer to the apply step only if a _direct_ dependency of the data resource has a change pending, and allow a plan-time read if there's a pending change in an indirect dependency. This allowed us to preserve some compatibility with the questionable historical behavior of always reading data resources proactively unless the configuration contains unknown values, since the arguably-more-correct behavior would've been a regression for anyone who had been depending on that before. Since preconditions and postconditions didn't exist until now, we are not constrained in the same way by backward compatibility, and so we can adopt the more correct behavior in the case where a data resource has conditions specified. This does unfortunately make the handling of data resources with conditions subtly inconsistent with those that don't, but this is a better situation than the alternative where it would be easy to get into a trapped situation where the remote system is invalid and it's impossible to plan the change that would make it valid again because the conditions evaluate too soon, prior to the fix being applied.		4 years ago
