James Bardin	a2b189fd71	handle to expression from json files ... Because expression from JSON files are handled differently from HCL, we need to deal with these manually when evaluating the special "to" syntax. We take the same approach as was done for replace_triggered_by, where the raw string is extracted from the json expression, and re-evaluated as an HCL expression.	3 years ago
Alisdair McDiarmid	64cf53bd7e	configs: Fix check block configuration diagnostics ... When validating self-references for resource and data source preconditions and postconditions, we previously did not nil-check the block's condition field, which caused a panic when the block had no condition. While fixing this I noticed that we were not validating that there are no self-references in the error message, so fixed that.	4 years ago

Alisdair McDiarmid	b06fe04621	core: Check rule error message expressions ... Error messages for preconditions, postconditions, and custom variable validations have until now been string literals. This commit changes this to treat the field as an HCL expression, which must evaluate to a string. Most commonly this will either be a string literal or a template expression. When the check rule condition is evaluated, we also evaluate the error message. This means that the error message should always evaluate to a string value, even if the condition passes. If it does not, this will result in an error diagnostic. If the condition fails, and the error message also fails to evaluate, we fall back to a default error message. This means that the check rule failure will still be reported, alongside diagnostics explaining why the custom error message failed to render. As part of this change, we also necessarily remove the heuristic about the error message format. This guidance can be readded in future as part of a configuration hint system.	4 years ago
Martin Atkins	9076400436	configs: Decode preconditions and postconditions ... This allows precondition and postcondition checks to be declared for resources and output values as long as the preconditions_postconditions experiment is enabled. Terraform Core doesn't currently know anything about these features, so as of this commit declaring them does nothing at all.	4 years ago
Kristin Laemmert	3acb5e2841	configs: add decodeMovedBlock behind a locked gate. (#28973) ... This PR adds decoding for the upcoming "moved" blocks in configuration. This code is gated behind an experiment called EverythingIsAPlan, but the experiment is not registered as an active experiment, so it will never run (there is a test in place which will fail if the experiment is ever registered). This also adds a new function to the Targetable interface, AddrType, to simplifying comparing two addrs.Targetable. There is some validation missing still: this does not (yet) descend into resources to see if the actual resource types are the same (I've put this off in part because we will eventually need the provider schema to verify aliased resources, so I suspect this validation will have to happen later on).	5 years ago
Martin Atkins	31349a9c3a	Move configs/ to internal/configs/ ... This is part of a general effort to move all of Terraform's non-library package surface under internal in order to reinforce that these are for internal use within Terraform only. If you were previously importing packages under this prefix into an external codebase, you could pin to an earlier release tag as an interim solution until you've make a plan to achieve the same functionality some other way.	5 years ago
