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	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
