Martin Atkins	8fd29e9439	stacks: Preserve prior state from plan to apply We need to retain the prior state (in a form that Terraform Core's modules runtime can accept) between the plan and apply phases because Terraform uses it to verify that the provider's "final plan" is consistent with the initial plan. We previously tried to do this by reusing the "old" value from the planned change, but that's not really possible in practice because of the historical implementation detail that Terraform wants state information in a JSON format and plan information in MessagePack. This also contains the beginnings of handling the "discarding" of unrecognized keys from the state data structures, although we'll probably need to do more in that area later since this is just the bare minimum.	2 years ago

Martin Atkins	d99985720f	stacks: Carry input variable values from plan to apply We need to preserve the input variable values provided during the plan phase so we can reuse them during the apply phase to recalculate derived results based on new information learned during the apply process. We also need to recalculate the input values for individual components during the apply phase, so we can react to previously-unknown values that come from other upstream components.	2 years ago
Martin Atkins	ba8af34679	stackplan: Stub of runtime models for representing plans This package includes both some model types to represent plans (and parts thereof) in memory, and logic for translating between the in-memory representation and our protocol-buffers-based storage serialization. Unlike the traditional saved plan file format, the stacks model for planning is slightly asymmetrical: while constructing the plan the system will emit chunks of the overall plan piecemeal as PlannedChange values, streamed to the rpcapi client. When reloading that plan to apply it, the client must provide all of the raw plan blobs in sequence which we can then decode one by one to construct a single Plan object covering the entire effect of the plan. Another intentional asymmetry is that PlannedChange includes enough information to produce both the raw internal plan representation and the public-facing plan description, whereas Plan only includes the subset of information actually required for Terraform Core to apply the plan, from the raw internal representation exclusively.	2 years ago
