Martin Atkins	30e2fd6525	Handle marks a little more consistently ... In the very first implementation of "sensitive values" we were unfortunately not disciplined about separating the idea of "marked value" from the idea of "sensitive value" (where the latter is a subset of the former). The first implementation just assumed that any marking whatsoever meant "sensitive". We later improved that by adding the marks package and the marks.Sensitive value to standardize on the representation of "sensitive value" as being a value marked with _that specific mark_. However, we did not perform a thorough review of all of the mark-handling codepaths to make sure they all agreed on that definition. In particular, the state and plan models were both designed as if they supported arbitrary marks but then in practice marks other than marks.Sensitive would be handled in various inconsistent ways: dropped entirely, or interpreted as if marks.Sensitive, and possibly do so inconsistently when a value is used only in memory vs. round-tripped through a wire/file format. The goal of this commit is to resolve those oddities so that there are now two possible situations: - General mark handling: some codepaths genuinely handle marks generically, by transporting them from input value to output value in a way consistent with how cty itself deals with marks. This is the ideal case because it means we can add new marks in future and assume these codepaths will handle them correctly without any further modifications. - Sensitive-only mark preservation: the codepaths that interact with our wire protocols and file formats typically have only specialized support for sensitive values in particular, and lack support for any other marks. Those codepaths are now subject to a new rule where they must return an error if asked to deal with any other mark, so that if we introduce new marks in future we'll be forced either to define how we'll avoid those markings reaching the file/wire formats or extend the file/wire formats to support the new marks. Some new helper functions in package marks are intended to standardize how we deal with the "sensitive values only" situations, in the hope that this will make it easier to keep things consistent as the codebase evolves in future. In practice the modules runtime only ever uses marks.Sensitive as a mark today, so all of these checks are effectively covering "should never happen" cases. The only other mark Terraform uses is an implementation detail of "terraform console" and does not interact with any of the codepaths that only support sensitive values in particular.	2 years ago

Martin Atkins	a4d61733f6	stackplan: Include extra info in raw component instance plan ... We'll now track the planned action, the component addresses we depend on, and the planned output values.	2 years ago
Martin Atkins	bcccd67e32	tfstackdata1: A local DynamicValue message type ... Previously we were directly using the planproto.DynamicValue message type, but that's symmetrical with plans.DynamicValue in that it encodes only the value itself and not associated metadata such as the paths that have sensitive value marks. This new tfstackdata1.DynamicValue therefore echoes terraform1.DynamicValue by carrying both the value and the metadata together. This implies a slight change to one of the existing message types that was encoding a map of planned input values for each component instance, but in practice we're not currently making use of that data anyway -- it's there to enable a hypothetical extra correctness check in the stacks runtime so that we can detect inconsistency problems closer to their source -- and so this change doesn't affect anything in practice. Before we make use of it we'll probably want to change the internal API a little so that we can preserve the sensitive value metadata on those values, but that's beyond the scope of this PR. The main point of adding this is to track the output values for a component instance as part of the raw state, and so the new field for that is also added here although nothing will read or write it yet. Actual use of that new field will follow in future commits.	2 years ago
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	54622c68a5	stackstate: Generate "raw state" objects for resource instance objects ... Previously we just had a stub that only generated basic external description objects. Now we'll also emit "raw state" objects for these, and have some initial support for deposed objects too.	2 years ago
