Lucas Bajolet	9076c7b24a	internal/dag: remove unused code ... Since the DAG package was lifted from Terraform, its contents are more than what we need for now, so this commit cleans-up the package to keep only the currently needed parts of code. If we need to support more in the future, we can revert this commit, or pickup the changes again from Terraform.	2 years ago
Lucas Bajolet	09774aaeb8	internal/dag: adapt Validate to not check for Root ... The implementation of the DAG as extracted from Terraform relied on a Root vertex being injected into the graph as the last node to visit. This is used as a sanity check for Terraform, but doesn't apply to our use-case for now, as we are always executing everything and have no need for this root node. Instead, we change how Validate operates so it does not error in case there is no valid root node for the graph, but enables us calling it to check for self-referencing edges, and circular dependencies.	2 years ago
Lucas Bajolet	673c13ebe7	internal: add dag package ... The dag package is a port over from Terraform to Packer, changing what little there was to fit our current dependency ecosystem. Most of the changes are on the type of diagnostics returned, as Terraform has its own type for them, while we rely on hcl's Diagnostics. Other than that, the functionality is essentially equivalent, and the code was barely touched.	2 years ago
