In addition to `list_url` make sure the package has the `url` attribute
set before attempting to add urls from a list. This is to cover the case
where there may be a `list_url` specified in tandem with a
`url_for_version`.
This commit will make urls from list_url only checked if `list_url` is
set in the package file. This makes more sense as there is no need to
check for those if the attribute is not present. If `url` is present and
`list_url` is not then it would result in the same url. If
`url_for_version` is used then that will not work anyway.
This PR allows archive file retrieval from urls derived from the
`list_url` setting in a package file. This allows for continued
retrieval of checksummed archive files even when they are moved to a new
remote location when a package is updated upstream.
Set up the environment for the Intel compilers and tools. This commit
does the following:
- Unset variables that were incorrect from the auto guess prefix
inspections.
- Add a RemovePath environment_modifications_formats for dotkit.
- Set the module environment variables appropriate for the different
variants.
- Change the component logic so that the '+all' variant works. It was
getting split by letter and leaving COMPONENTS empty.
- Added a variant checking function.
- Added NONRPM_DB_DIR to the silent.cfg so that the product database
goes to the installation directory.
- With the product database in prefix the code to remove the product
database file from the home directory is no longer needed and was
removed.
- Reformat the 'tools' variant description.
There are probably more variables needed for the '+tools' for the
'professional' product version but I do not have access to that.
- Default scope is versioned with spack and can be overridden by site
or user config.
- Default scope provides sensible default concretization preferences
for all of Spack.
- per-platform concretization scope can be added later (to force a
particular MPI on, e.g., Cray systems)
- Consolidated code to read spec.yaml and database index.yaml into
one method (`read_yaml_dep_specs()`) in spec.py.
- Code understands old hash format, tuple format, and dicts for dep
specs, for backward compatibility.
- Spec YAML now uses a dict with keys to represent dep specs (this is
more future-proof).
- Dep specs no longer contain !!py-tuple entries in YAML (only lists
properly YAML-ize)
- bump database version.
