Martin Atkins	1714729f87	stackeval: terraform.applying symbol This symbol produces an ephemeral boolean value that's true when the stack evaluator is configured for applying and false otherwise. The primary purpose of this is to allow specifying a more privileged auth role in a provider configuration during the apply phase, while allowing the plan phase to use a read-only or otherwise-less-privileged role.	2 years ago
Martin Atkins	5bfdb12098	stackaddrs: Absolute references and referenceables This allows us to talk about references between expressions in absolute terms, taking into account the stack where a particular expression would be resolved. This isn't an appropriate representation for references like each.key, since those require a more specific scope than just a stack, but that's okay because those contextual reference types can't depend on anything other than what they are embedded inside anyway, and so we never need to consider them when we're doing global reference analysis.	2 years ago
Martin Atkins	8a99c3c0e5	stacks+rpcapi: Add some missing copyright comments	2 years ago
Martin Atkins	333c502990	stackeval: Support each.key, each.value, count.index and self references For all contexts where these have a defined value, they can now be used in expressions and evaluate to whatever they ought to evaluate to.	2 years ago
Martin Atkins	13edd30479	stackeval: Test-only globals Because many stacks language features are dependent on others to do useful work, it's tempting to focus only on integration testing of combinations of features used together. However, we known from our experience with the modules runtime (the "terraform" package) that over time this becomes a huge maintenance burden, because any non-trivial change tends to invalidate hundreds or thousands of integration tests, and because of their broad scope its often hard in retrospect to figure out what exactly a particular test was aiming to test vs. what it was just relying on as a side-effect. To try to minimize these cross-dependencies and thus enable something closer to unit testing, here we introduce a special kind of symbol to the stacks language which is available only to unit tests in this package. "Test-only globals" -- an intentionally-clunky name to avoid squatting on useful names -- can be set as part of the Main object and, when defined, are available for use in all situations where we perform expression evaluation against a stack. The "globals" in the name represents that, unlike just about everything else, they are defined once but available in all stacks in the configuration tree. This design is a tradeoff: it introduces a bunch of extra code that is here entirely to support testing, but hopefully this code is segregated enough from everything else that it's unlikely to change significantly under future maintenance, thereby hopefully minimizing the need for future cross-cutting test maintenance too.	2 years ago
Martin Atkins	89776cd2a6	stackstate: Initial work on decoding and the state model This is a sketch of the overall structure of the prior state decoder and the model type it populates. Before we can complete this we'll need to slightly rework how the apply phase emits the raw events that this is consuming, and in particular to change the raw state representation to be JSON-based to match with how Terraform Core expects to receive it once reloaded. That will follow in later commits.	2 years ago
Martin Atkins	434e199675	stackaddrs: Add HashiCorp copyright comments	2 years ago
Martin Atkins	f347d0a441	stackaddrs: Handle instance keys in embedded stack references Previously this logic was wrong, because it had already consumed the two leading traversal steps before checking if there was anything else.	2 years ago
Martin Atkins	385e37cae2	stackaddrs: fix some ParseAbsComponentInstance logic errors	2 years ago
Martin Atkins	c1e7abafc3	stackruntime: Configure and assign provider instances Instead of the temporary hack of hard-coding the built-in "terraform" provider, it's now possible to declare configurations for arbitrary providers and assign them to the provider configuration slots of the root module of each component.	2 years ago
Martin Atkins	edc02f2a06	stackaddrs: ConfigComponentForAbsInstance This helper discards all of the instance keys from an AbsComponentInstance to find the corresponding ConfigComponent.	2 years ago
Martin Atkins	ebab67b468	stackaddrs: AbsComponentInstance address parsing Addresses of this type will appear in some of our serialization formats and so we need a parser function which provides the inverse of the "String" method of this type.	2 years ago
Martin Atkins	e0797ab913	stackaddrs: Addresses for things inside components In the stacks model a component is essentially a container for a tree of normal Terraform modules, and so anything that can appear in a Terraform module can in principle appear inside a component. With that in mind here we define a generic type that can represent anything from package addrs belonging either to a stack configuration (before instance expansion) or to a stack instance (after instance expansion), and some aliases for a few combinations that make sense together, such as stackaddrs.AbsResourceInstance being an addrs.AbsResourceInstance belonging to a stackaddrs.AbsComponentInstance. We'll probably add more aliases here later, but this is a starting set that I expect will arise while implementing the planning-related models for stacks.	2 years ago
Martin Atkins	59a044dd6f	stackeval: The naming of promises If a stack configuration has a dependency cycle we'll tend to detect it by the promises failing to resolve due to a self-reference. Describing that situation to end-users has been historically hard in existing Terraform's dag-based implementation, and there are some similar challenges for this promise-based design too. To deal with it while minimizing runtime overhead in the happy path we'll teach the various objects to retroactively report names for the promises they've already instantiated and then only when we encounter the ErrSelfDependent error will we walk the tree of objects to find user-friendly names for all of the promises that have contributed to the results so far.	2 years ago
Martin Atkins	3d503f8e71	stackruntime: Stubbing the "interpreter" for stack configurations	2 years ago
Martin Atkins	e667352553	stacks/stackaddrs: Initial address types for stacks This serves a similar purpose to the "addrs" package for Terraform overall, but deals with concepts that are unique to the stacks language.	2 years ago
