When installing some/all specs from a buildcache, build edges are pruned from those specs. This can result in a much smaller effective DAG. Until now, `spack env depfile` would always generate a full DAG. Ths PR adds the `spack env depfile --use-buildcache` flag that was introduced for `spack install` before. This way, not only can we drop build edges, but also we can automatically set the right buildcache related flags on the specific specs that are gonna get installed. This way we get parallel installs of binary deps without redundancy, which is useful for Gitlab CI. |
