Martin Atkins	3dc3781904	stackruntime: Starting up and configuring provider plugins ... Each declared provider configuration is now started up and configured during planning. We don't actually do anything with them yet other than shut them down again once the plan is complete, but we'll improve on that in subsequent commits.	2 years ago
Martin Atkins	791a5fb8a6	stackruntime: Top-level "Validate" function ... This is the public entry point for the overall validation of an entire stack configuration. So far it supports validation only of input variables, embedded stack calls, and output values. We'll grow this to support other language constructs in later commits. This is a relatively large commit due to introducing various supporting infrastructure to help make evaluation possible at all. Subsequent commits will hopefully be more focused due to being able to depend on the foundations introduced here.	2 years ago
Martin Atkins	4754889950	stackruntime: Beginnings of Validate function ... This stubs out the basic structure of stackeval's equivalent of a graph walk, which is really just a recursive tree walk starting async tasks that might depend on each other via the abstractions in package "promising". This initial work is sufficient to validate the inputs to an embedded stack call when referring to input variables in the calling stack, showing that the expression evaluation model seems to be working and the use of promises to deal with dependency ordering seems viable.	2 years ago
