James Bardin	1b8617cef0	don't attempt to decode empty changes values ... An empty DynamicValue can't be decoded but indicates no state, so just return a NullVal.	7 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	1ced176fc6	plans: Track RequiredReplace as a cty.PathSet ... We were previously tracking this as a []cty.Path, but having it turned into a pathset on creation makes downstream use of it more convenient and ensures that it'll obey expected invariants like not containing the same path twice.	8 years ago
Martin Atkins	bd299b9a22	core: Re-implement EvalWriteDiff to work with new plan types	8 years ago
Martin Atkins	44bc7519a6	terraform: More wiring in of new provider types ... This doesn't actually work yet, but it builds and then panics in a pretty satisfying way.	8 years ago
Martin Atkins	dfe0988f10	plans: Record private data bytes as part of resource change ... This allows a provider to retain arbitrary extra data in the plan and make use of it during apply. The contents are not used by Terraform and never shown to the user.	8 years ago
Martin Atkins	b7db32b819	plans: separate types for encoded and decoded changes ... The types here were originally written to allow us to defer decoding of object values until schemas are available, but it turns out that this was forcing us to defer decoding longer than necessary and potentially decode the same value multiple times. To avoid this, we create pairs of types to represent the encoded and decoded versions and methods for moving between them. These types are identical to one another apart from how the dynamic values are represented.	8 years ago
