`spack graph` has been reworked to use:
- Jinja templates
- builder objects to construct the template context when DOT graphs are requested.
This allowed to add a new colored output for DOT graphs that highlights both
the dependency types and the nodes that are needed at runtime for a given spec.
Caches used by repositories don't reference the global spack.repo.path instance
anymore, but get the repository they refer to during initialization.
Spec.virtual now use the index, and computation done to compute the index
use Repository.is_virtual_safe.
Code to construct mock packages and mock repository has been factored into
a unique MockRepositoryBuilder that is used throughout the codebase.
Add debug print for pushing and popping config scopes.
Changed spack.repo.use_repositories so that it can override or not previous repos
spack.repo.use_repositories updates spack.config.config according to the modifications done
Removed a peculiar behavior from spack.config.Configuration where push would always
bubble-up a scope named command_line if it existed
- [x] add `concretize.lp`, `spack.yaml`, etc. to licensed files
- [x] update all licensed files to say 2013-2021 using
`spack license update-copyright-year`
- [x] appease mypy with some additions to package.py that needed
for oneapi.py
* Added a function that concretizes specs together
* Specs concretized together are copied instead of being referenced
This makes the specs different objects and removes any reference to the
fake root package that is needed currently for concretization.
* Factored creating a repository for concretization into its own function
* Added a test on overlapping dependencies
Adds four new sub-commands to the buildcache command:
1. save-yaml: Takes a root spec and a list of dependent spec names,
along with a directory in which to save yaml files, and writes out
the full spec.yaml for each of the dependent specs. This only needs
to concretize the root spec once, then indexes it with the names of
the dependent specs.
2. check: Checks a spec (via either an abstract spec or via a full
spec.yaml) against remote mirror to see if it needs to be rebuilt.
Comparies full_hash stored on remote mirror with full_hash computed
locally to determine whether spec needs to be rebuilt. Can also
generate list of specs to check against remote mirror by expanding
the set of release specs expressed in etc/spack/defaults/release.yaml.
3. get-buildcache-name: Makes it possible to attempt to read directly
the spec.yaml file on a remote or local mirror by providing the path
where the file should live based on concretizing the spec.
4. download: Downloads all buildcache files associated with a spec
on a remote mirror, including any .spack, .spec, and .cdashid files
that might exist. Puts the files into the local path provided on
the command line, and organizes them in the same hierarchy found on
the remote mirror
This commit also refactors lib/spack/spack/util/web.py to expose
functionality allowing other modules to read data from a url.
