With the introduction of explicit "null" in 0.12 it's possible for a value that is unknown during plan to become a known null during apply, so we need to slightly weaken our validation rules to accommodate that, in particular skipping the validation of conflicting attributes if the result could potentially be valid after the unknown values become known. This change is in the codepath that is common to both 0.12 and 0.11 callers, but that's safe because 0.11 re-runs validation during the apply step and so will still catch problems here, albeit in the apply step rather than in the plan step, thus matching the 0.12 behavior. This new behavior is a superset of the old in the sense that everything that was valid before is still valid. The implementation here also causes us to skip all other validation for an attribute whose value is unknown. Most of the downstream validation functions handle this directly anyway, but again this doesn't add any new failure cases, and should clean up some of the rough edges we've seen with unknown values in 0.11 once people upgrade to 0.12-compatible providers. Any issues we now short-circuit during planning will still be caught during apply. While working on this I found that the existing "Not a list" test was not actually testing the correct behavior, so this also includes a tweak to that to ensure that it really is checking the "should be a list" path rather than the "cannot be set" codepath it was inadvertently testing before. |

Helper Libraries
This folder contains helper libraries for Terraform plugins. A running joke is that this is "Terraform standard library" for plugins. The goal of the packages in this directory are to provide high-level helpers to make it easier to implement the various aspects of writing a plugin for Terraform.
