Martin Atkins	87fe6cbecd	plans/objchange: Don't panic when prior state contains nested map blocks ... We were using the wrong cty operation to access map members, causing a panic whenever a prior value was present for a resource type with a nested block backed by a map value.	7 years ago
Martin Atkins	e831182c8d	plans/objchange: Hide sensitive attribute values in error messages ... Since these error messages get printed in Terraform's output and we encourage users to share them as part of bug reports, we should avoid including sensitive information in them to reduce the risk of accidental exposure.	7 years ago
Martin Atkins	fec6e0328d	plans/objchange: AssertPlanValid function ... Completing our set of provider result safety-check functions, AssertPlanValid checks a result from a provider's PlanResourceChange to make sure it doesn't propose a change that is not valid within the user model of Terraform. Specifically, it forbids the provider from planning a value that contradicts what the user gave in configuration, which is important to ensure that making a reference to an attribute elsewhere in the configuration will produce exactly the given result, as users reasonably expect. Providers _are_ allowed (and, in fact, required) to make changes to any Computed attribute values declared in the schema in order to fill in the default values that the provider has generated. Later checks during the apply phase will ensure that the provider remains true to these planned values, to ensure that Terraform can keep its promise of doing exactly what was planned or presenting an error explaining why not.	7 years ago
