James Bardin	f0e51aca1a	test a nil computed value within an expression Comparing a nil-computed value was returning unknown, preventing the data source from being evaluated.	7 years ago
James Nugent	fb150ef72f	provider/test: Add test of data source count.index This adds a unit test to the test provider that verifies count.index behaves correctly. Although not ideal this is hard to implement as a context test without changing around the (non helper/schema) implementation of the x_data_source.	10 years ago
Paul Hinze	4a1b36ac0d	core: rerun resource validation before plan and apply In #7170 we found two scenarios where the type checking done during the `context.Validate()` graph walk was circumvented, and the subsequent assumption of type safety in the provider's `Diff()` implementation caused panics. Both scenarios have to do with interpolations that reference Computed values. The sentinel we use to indicate that a value is Computed does not carry any type information with it yet. That means that an incorrect reference to a list or a map in a string attribute can "sneak through" validation only to crop up... 1. ...during Plan for Data Source References 2. ...during Apply for Resource references In order to address this, we: * add high-level tests for each of these two scenarios in `provider/test` * add context-level tests for the same two scenarios in `terraform` (these tests proved _really_ tricky to write!) * place an `EvalValidateResource` just before `EvalDiff` and `EvalApply` to catch these errors * add some plumbing to `Plan()` and `Apply()` to return validation errors, which were previously only generated during `Validate()` * wrap unit-tests around `EvalValidateResource` * add an `IgnoreWarnings` option to `EvalValidateResource` to prevent active warnings from halting execution on the second-pass validation Eventually, we might be able to attach type information to Computed values, which would allow for these errors to be caught earlier. For now, this solution keeps us safe from panics and raises the proper errors to the user. Fixes #7170	10 years ago
