This adds spack.util.spack_yaml.anchorify, which takes a non-cyclic dict/list structure, and replaces identical values with (back) references to the first instance, so that yaml serialization will use anchors. `repr` is used to identify sub-dags, which in principle is quadratic complexity in depth of the graph, but in practice the depth is O(1) so this should not matter. Then this is used in CI to reduce the size of generated YAML files to 30% of their original size. |
