James Bardin	8e7a9b6312	output test for plan with no root output changes Module outputs do not show up in the plan, and are not rendered in the UI.	6 years ago
Alisdair McDiarmid	b335918c3c	backend: Only show root module output changes When rendering planned output changes, we need to filter the plan's output changes to ensure that only root module outputs which have changed are rendered. Otherwise we will render changes for submodule outputs, and (with concise diff disabled) render unchanged outputs also.	6 years ago
James Bardin	bc82347a04	fix tests Update tests to match the new behavior. Some were incorrect, some no longer make sense, and some just weren't setup to handle th plan api calls.	6 years ago
Martin Atkins	31a4b44d2e	backend/local: treat output changes as side-effects to be applied This is a baby-step towards an intended future where all Terraform actions which have side-effects in either remote objects or the Terraform state can go through the plan+apply workflow. This initial change is focused only on allowing plan+apply for changes to root module output values, so that these can be written into a new state snapshot (for consumption by terraform_remote_state elsewhere) without having to go outside of the primary workflow by running "terraform refresh". This is also better than "terraform refresh" because it gives an opportunity to review the proposed changes before applying them, as we're accustomed to with resource changes. The downside here is that Terraform Core was not designed to produce accurate changesets for root module outputs. Although we added a place for it in the plan model in Terraform 0.12, Terraform Core currently produces inaccurate changesets there which don't properly track the prior values. We're planning to rework Terraform Core's evaluation approach in a forthcoming release so it would itself be able to distinguish between the prior state and the planned new state to produce an accurate changeset, but this commit introduces a temporary stop-gap solution of implementing the logic up in the local backend code, where we can freeze a snapshot of the prior state before we take any other actions and then use that to produce an accurate output changeset to decide whether the plan has externally-visible side-effects and render any changes to output values. This temporary approach should be replaced by a more appropriately-placed solution in Terraform Core in a release, which should then allow further behaviors in similar vein, such as user-visible drift detection for resource instances.	6 years ago
