James Bardin	8e3728af54	rename methods for ConfigResource changes	6 years ago
James Bardin	18ca98a064	GetConfigResourceChanges from plans In order to find any changes related to a particular configuration address, we need a new method to get changes to all possible instances.	6 years ago
James Bardin	2490e6c84b	provide a method to get all modules changes Since modules need to be evaluated as whole objects, yet the outputs are all handled individually, we need a method to collect and return all output changes for a module from the plan, including all known module instances.	6 years ago
Martin Atkins	ab62b330c1	core: Allow planned output changes to be updated during apply If plan and apply are both run against the same context then we still have the planned output values in memory while we're doing the apply walk, so we need to make sure to update them along with the state as we learn the final known values of each output. There were actually two different bugs here: - We weren't removing any existing planned change for an output when setting a new one. In retrospect a map would've been a better data structure for the output changes, rather than a slice to mimic what we do for resource instance objects, but for now we'll leave the structures alone and clean up as needed. (The set of outputs should be small for any reasonable configuration, so the main impact of this is some ugly code in RemoveOutputChange.) - RemoveOutputChange itself had a bug where it was iterating over the resource changes rather than the output changes. This didn't matter before because we weren't actually using that function, but now we are. This fix is confirmed by restoring various existing context apply tests back to passing again.	8 years ago
Martin Atkins	d53c3d5c1b	plans: Retain output value changes for all outputs in memory During the plan operation we need to retain _somewhere_ the planned changes for all outputs so we can refer to them during expression evaluation. For consistency with how we handle resource instance changes, we'll keep them in the plan so we can properly retain unknown values, which cannot be written to state. As with output values in the state, only root output plans are retained in a round-trip through the on-disk plan file format, but that's okay because we can trivially re-calculate all of these during apply. We include the _root_ outputs in the plan file only because they are externally-visible side effects that ought to be included in any rendering of the plan made from the plan file for user inspection.	8 years ago
Martin Atkins	1d672623eb	core: Remove changes from the plan after they are applied	8 years ago
Martin Atkins	2f0e5d93c8	plans: ChangesSync.GetResourceInstanceChange must copy the change This is promised in its doc comment, but wasn't actually done in practice.	8 years ago
Martin Atkins	3d86dc51e0	core: Re-implement EvalReadDiff for the new plan types This also includes passing in the provider schema to a few more EvalNodes that were expecting it but not getting it, in order to be able to successfully test the implementation of EvalReadDiff here.	8 years ago
Martin Atkins	bd299b9a22	core: Re-implement EvalWriteDiff to work with new plan types	8 years ago
Martin Atkins	a3403f2766	terraform: Ugly huge change to weave in new State and Plan types Due to how often the state and plan types are referenced throughout Terraform, there isn't a great way to switch them out gradually. As a consequence, this huge commit gets us from the old world to a _compilable_ new world, but still has a large number of known test failures due to key functionality being stubbed out. The stubs here are for anything that interacts with providers, since we now need to do the follow-up work to similarly replace the old terraform.ResourceProvider interface with its replacement in the new "providers" package. That work, along with work to fix the remaining failing tests, will follow in subsequent commits. The aim here was to replace all references to terraform.State and its downstream types with states.State, terraform.Plan with plans.Plan, state.State with statemgr.State, and switch to the new implementations of the state and plan file formats. However, due to the number of times those types are used, this also ended up affecting numerous other parts of core such as terraform.Hook, the backend.Backend interface, and most of the CLI commands. Just as with `5861dbf3fc` before, I apologize in advance to the person who inevitably just found this huge commit while spelunking through the commit history.	8 years ago
