This PR is meant to move code with "business logic" from `spack.cmd.buildcache` to appropriate core modules[^1]. Modifications: - [x] Add `spack.binary_distribution.push` to create a binary package from a spec and push it to a mirror - [x] Add `spack.binary_distribution.install_root_node` to install only the root node of a concrete spec from a buildcache (may check the sha256 sum if it is passed in as input) - [x] Add `spack.binary_distribution.install_single_spec` to install a single concrete spec from a buildcache - [x] Add `spack.binary_distribution.download_single_spec` to download a single concrete spec from a buildcache to a local destination - [x] Add `Spec.from_specfile` that construct a spec given the path of a JSON or YAML spec file - [x] Removed logic from `spack.cmd.buildcache` - [x] Removed calls to `spack.cmd.buildcache` in `spack.bootstrap` - [x] Deprecate `spack buildcache copy` with a message that says it will be removed in v0.19.0 [^1]: The rationale is that commands should be lightweight wrappers of the core API, since that helps with both testing and scripting (easier mocking and no need to invoke `SpackCommand`s in a script). |
