Fixes #366 To reproduce #366, add ``` bases: - . ``` to `examples/helloWorld/kustomization.yaml`, attempt to build it, and enjoy the stack overflow. This PR fixes this by adding history to file loaders, allowing one to avoid cycles in overlay->base relationships. To make entry points clearer, this PR exposes only two public ways to make a fresh (no-history) loader * rooted at `/` * rooted at the process's current working directory. When making a new loader from an existing loader, retaining history along an overlay trace, the only allowed use is to go deeper into a file hierarchy, or go up and over to a never before visited sibling. This fix can probably be defeated by devious symbolic links.
